Introduction
OntoNotes Release 5.0 is the final release of the OntoNotes project, a collaborative effort between BBN Technologies, the University of Colorado, the University of Pennsylvania and the University of Southern Californias Information Sciences Institute. The goal of the project was to annotate a large corpus comprising various genres of text (news, conversational telephone speech, weblogs, usenet newsgroups, broadcast, talk shows) in three languages (English, Chinese, and Arabic) with structural information (syntax and predicate argument structure) and shallow semantics (word sense linked to an ontology and coreference).
OntoNotes Release 5.0 contains the content of earlier releases -- OntoNotes Release 1.0 LDC2007T21, OntoNotes Release 2.0 LDC2008T04, OntoNotes Release 3.0 LDC2009T24 and OntoNotes Release 4.0 LDC2011T03 -- and adds source data from and/or additional annotations for, newswire (News), broadcast news (BN), broadcast conversation (BC), telephone conversation (Tele) and web data (Web) in English and Chinese and newswire data in Arabic. Also contained is English pivot text (Old Testament and New Testament text). This cumulative publication consists of 2.9 million words with counts shown in the table below.

The OntoNotes project built on two time-tested resources, following the Penn Treebank for syntax and the Penn PropBank for predicate-argument structure. Its semantic representation includes word sense disambiguation for nouns and verbs, with some word senses connected to an ontology, and coreference.
Data
Documents describing the annotation guidelines and the routines for deriving various views of the data from the database are included in the documentation directory of this release. The annotation is provided both in separate text files for each annotation layer (Treebank, PropBank, word sense, etc.) and in the form of an integrated relational database (ontonotes-v5.0.sql.gz) with a Python API to provide convenient cross-layer access.
It is a known issue that this release contains some non-validating XML files. The included tools, however, use a non-validating XML parser to parse the .xml files and load the appropriate values.
Tools
This release includes OntoNotes DB Tool v0.999 beta, the tool used to assemble the database from the original annotation files. It can be found in the directory tools/ontonotes-db-tool-v0.999b. This tool can be used to derive various views of the data from the database, and it provides an API that can implement new queries or views. Licensing information for the OntoNotes DB Tool package is included in its source directory.

In order to understand how the firm–project hybridisation process occurs, we present the results of an online survey of participants in the Debian project, as well as interviews with Debian Developers. We find that the intermingling of the commercial logic of the firm and the communal logic of the project requires rhetorical legitimation. We analyse the discourses used to legitimise firm–project cooperation as well as the organisational mechanisms which facilitate this cooperation. A first phase of legitimation, based on firm adoption of open licenses and developer self-fulfilment, aims to erase the commercial/communal divide. A second more recent phase seeks to professionalise work relations inside the project and, in doing so, challenges the social order which restricts participation in FOSS. Ultimately, hybridisation raises the question of the fair distribution of the profits firms derive from FOSS.","2021-05-01","2025-03-18 01:50:03","2025-03-18 01:50:03","2025-03-18 01:50:03","1157-1180","","5","23","","","‘Open source has won and lost the war’","","","","","","","EN","","","","","SAGE Journals","","Publisher: SAGE Publications","","/Users/mgone/Zotero/storage/B6SPYS83/O’Neil et al. - 2021 - ‘Open source has won and lost the war’ Legitimisi.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In practice, developers are often classified according to the dichotomy of core and peripheral roles. Typically, count-based operationalizations, which rely on simple counts of individual developer activities (e.g., number of commits), are used for this purpose, but there is concern regarding their validity and ability to elicit meaningful insights. To shed light on this issue, we investigate whether count-based operationalizations of developer roles produce consistent results, and we validate them with respect to developers' perceptions by surveying 166 developers. Improving over the state of the art, we propose a relational perspective on developer roles, using fine-grained developer networks modeling the organizational structure, and by examining developer roles in terms of developers' positions and stability within the developer network. In a study of 10 substantial open-source projects, we found that the primary difference between the count-based and our proposed network-based core-peripheral operationalizations is that the network-based ones agree more with developer perception than count-based ones. Furthermore, we demonstrate that a relational perspective can reveal further meaningful insights, such as that core developers exhibit high positional stability, upper positions in the hierarchy, and high levels of coordination with other core developers, which confirms assumptions of previous work.","2017-05-20","2025-03-18 02:09:59","2025-03-18 02:09:59","2025-03-17","164–174","","","","","","Classifying developers into core and peripheral","ICSE '17","","","","IEEE Press","Buenos Aires, Argentina","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/YQNXDP3W/Joblin et al. - 2017 - Classifying developers into core and peripheral a.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers’ positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-05-26","2025-03-18 02:10:08","2025-03-18 02:10:08","2025-03-18 02:10:08","86:1–86:29","","4","32","","","Hierarchical and Hybrid Organizational Structures in Open-source Software Projects","","","","","","","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/CFYGUHXL/Joblin et al. - 2023 - Hierarchical and Hybrid Organizational Structures .pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm–community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.","2005-05-01","2025-03-18 02:23:34","2025-03-18 02:23:34","2025-03-18 02:23:34","481-493","","4","34","","Research Policy","Relationships between open source software companies and communities","","","","","","","","","","","","ScienceDirect","","","","/Users/mgone/Zotero/storage/P3RW49SA/S0048733305000405.html","","","Open source software; Communities; Relationships","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study used purposeful sampling of companies that have an expressed interest in OS, and the survey was conducted using a set of pre-prepared questions. Its goal was to investigate the extent to which OS has influenced business thinking, as seen from the standpoint of stakeholders. We found that uptake is much higher than reported in earlier studies, but as with previous studies, activity is still concentrated in small and medium-sized enterprises (SMEs). There is increased evidence of interest beyond the simple use of OS components at the infrastructure level. Further, a significant proportion of the companies studied are supporting the OS community as well as benefiting from it.

With the increasing interest in the literature on continuous practices, it is important to systematically review and synthesize the approaches, tools, challenges, and practices reported for adopting and implementing continuous practices. This paper aimed at systematically reviewing the state of the art of continuous practices to classify approaches and tools, identify challenges and practices in this regard, and identify the gaps for future research. We used the systematic literature review method for reviewing the peer-reviewed papers on continuous practices published between 2004 and June 1, 2016. We applied the thematic analysis method for analyzing the data extracted from reviewing 69 papers selected using predefined criteria. We have identified 30 approaches and associated tools, which facilitate the implementation of continuous practices in the following ways: (1) reducing build and test time in continuous integration (CI); (2) increasing visibility and awareness on build and test results in CI; (3) supporting (semi-) automated continuous testing; (4) detecting violations, flaws, and faults in CI; (5) addressing security and scalability issues in deployment pipeline; and (6) improving dependability and reliability of deployment process. We have also determined a list of critical factors, such as testing (effort and time), team awareness and transparency, good design principles, customer, highly skilled and motivated team, application domain, and appropriate infrastructure that should be carefully considered when introducing continuous practices in a given organization. The majority of the reviewed papers were validation (34.7%) and evaluation (36.2%) research types. This paper also reveals that continuous practices have been successfully applied to both greenfield and maintenance projects. Continuous practices have become an important area of software engineering research and practice. While the reported approaches, tools, and practices are addressing a wide range of challenges, there are several challenges and gaps, which require future research work for improving the capturing and reporting of contextual information in the studies reporting different aspects of continuous practices; gaining a deep understanding of how software-intensive systems should be (re-) architected to support continuous practices; and addressing the lack of knowledge and tools for engineering processes of designing and running secure deployment pipelines.","2017","2025-03-18 04:36:29","2025-03-18 04:36:29","2025-03-18 04:36:29","3909-3943","","","5","","","Continuous Integration, Delivery and Deployment","","","","","","","","","","","","IEEE Xplore","","Conference Name: IEEE Access","","/Users/mgone/Zotero/storage/TUYSGS3V/Shahin et al. - 2017 - Continuous Integration, Delivery and Deployment A.pdf; /Users/mgone/Zotero/storage/MT2CYNK8/7884954.html","","","Organizations; Software engineering; Software; Systematics; empirical software engineering; Testing; systematic literature review; Bibliographies; Production; continuous delivery; continuous deployment; Continuous integration; continuous software engineering","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Yet, these platforms are contested battlegrounds where stakeholder power struggles reflect and influence broader societal turbulence. In the emerging era, alongside the blinding speed and global reach of the gig economy are looming specters of rentier capitalism, digi-serfdom, misinformation, data exploitation, digital addiction, and near-ungovernable algorithmic agents. To date, scholarly focus on digital platforms has been on their transactional features and impacts, dimensionalizing governance mechanisms as emanating from old economy conceptions of bottom-up or top-down checks and balances, or incentives and efficiencies. These emphases, while useful for understanding managerial control of digital platforms, largely ignore the extent to which digital platforms are contested organizational spaces, shaped by complex power dynamics. Foucault (1998: 63) asserted that power is everywhere, and that those who hold power are rarely well-understood by those who are subject to it. In seeking to rebalance and reorient digital platform research, we analyze and integrate existing research along four dimensions that shape platform power dynamics: actors, relations, faces, and struggle. We establish a future research agenda—including six testable propositions—that more thoroughly engages the critical, yet untapped, expertise of management scholars concerning platform power.","2025-01","2025-03-18 05:00:34","2025-03-18 05:00:34","2025-03-18 05:00:34","265-297","","1","19","","ANNALS","Digital Battlegrounds","","","","","","","","","","","","journals.aom.org (Atypon)","","Publisher: Academy of Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

But our field's understanding of what motivates people to contribute to OSS is still fundamentally grounded in studies from the early 2000s. With the changed landscape of OSS, it is very likely that motivations to join OSS have also evolved. Through a survey of 242 OSS contributors, we investigate shifts in motivation from three perspectives: (1) the impact of the new OSS landscape, (2) the impact of individuals' personal growth as they become part of OSS communities, and (3) the impact of differences in individuals' demographics. Our results show that some motivations related to social aspects and reputation increased in frequency and that some intrinsic and internalized motivations, such as learning and intellectual stimulation, are still highly relevant. We also found that contributing to OSS often transforms extrinsic motivations to intrinsic, and that while experienced contributors often shift toward altruism, novices often shift toward career, fun, kinship, and learning. OSS projects can leverage our results to revisit current strategies to attract and retain contributors, and researchers and tool builders can better support the design of new studies and tools to engage and support OSS development.","2021-05","2025-03-18 14:34:26","2025-03-18 14:34:26","2025-03-18 14:34:26","1046-1058","","","","","","The Shifting Sands of Motivation","","","","","","","","","","","","IEEE Xplore","","ISSN: 1558-1225","","/Users/mgone/Zotero/storage/DSFI4AVV/9402044.html; /Users/mgone/Zotero/storage/Z53YE8KH/Gerosa et al. - 2021 - The Shifting Sands of Motivation Revisiting What .pdf","","","Open source software; open source; motivation; Tools; Ecosystems; Industries; Teamwork; Engineering profession; incentive; Transforms","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","2021 IEEE/ACM 43rd International Conference on Software Engineering (ICSE)","","","","","","","","","","","","","","",""

Effectively identifying such information in the high volume of communications across the different project channels, such as chats, emails, and issue comments, requires automated recognition of emotions and their causes. To enable this automation, large-scale software engineering-specific datasets that can be used to train accurate machine learning models are required. However, such datasets are expensive to create with the variety and informal nature of software projects' communication channels.In this paper, we explore zero-shot LLMs that are pre-trained on massive datasets but without being fine-tuned specifically for the task of detecting emotion causes in software engineering: ChatGPT, GPT-4, and flan-alpaca. Our evaluation indicates that these recently available models can identify emotion categories when given detailed emotions, although they perform worse than the top-rated models. For emotion cause identification, our results indicate that zero-shot LLMs are effective at recognizing the correct emotion cause with a BLEU-2 score of 0.598. To highlight the potential use of these techniques, we conduct a case study of the causes of Frustration in the last year of development of a popular open-source project, revealing several interesting insights.","2024-04-12","2025-03-18 15:16:05","2025-03-18 15:16:05","2025-03-18","1–13","","","","","","","ICSE '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/SBDLTN86/Imran et al. - 2024 - Uncovering the Causes of Emotions in Software Deve.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers’ inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers’ breaks. About 94% of the surveyed core developers agreed with our state model of inactivity; 71% and 79% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (~45%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who pause their activity have a ~35 to ~55% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to ~21–26%, with a ~54% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.","2022-03-19","2025-03-19 15:07:08","2025-03-19 15:07:08","2025-03-19 15:07:08","76","","3","27","","Empir Software Eng","Will you come back to contribute?","","","","","","","en","","","","","Springer Link","","","","/Users/mgone/Zotero/storage/AUFX9MET/Calefato et al. - 2022 - Will you come back to contribute Investigating th.pdf","","","Retention; Disengagement; Abandonment; Open-source communities; Repository mining; Turnover","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors’ uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors’ motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms’ sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms’ sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer’s OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer’s projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.","2022-09","2025-03-19 15:08:30","2025-03-19 15:08:30","2025-03-19 15:08:30","867-886","","3","33","","","Flourish or Perish?","","","","","","","","","","","","pubsonline.informs.org (Atypon)","","Publisher: INFORMS","","","","","open-source software; difference-in-differences; external contributions; internal contributions; openness; technological acquisitions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It draws on a study of online observation of a virtual community, i.e. an open source software (OSS) community. The paper examines general and specific advantages and disadvantages of the observer roles in online settings by relating these roles to the same roles assumed in offline settings. The study suggests that under the right circumstances online and offline observation may benefit from being combined as they complement each other well. Quality issues and factors important to elicit trustworthy observational data from online study settings, such as OSS communities, are discussed. A proposition is made concerning how threats to credibility and transferability in relation to online observation (i.e. lack of richness and detail, risk of misunderstandings) can be diminished, while maintaining the level of dependability (which is potentially high due to a greater degree of anonymity and ""isolation"" in online settings). The paper thus suggests that the less participative the researcher's online observer role is, the more s/he should consider introducing offline data collection techniques rather than adopting a more participative role in the observed online setting. This methodological discussion forms the basis for making a well-considered choice of online observer role rather than passively sliding into a role assigned by the setting. © 2011 FQS.","2011","2025-03-25 17:23:31","2025-03-25 17:23:31","","","","3","12","","","","","","","","","","","","","","","","","Type: Article","","","","Open source software; Qualitative research; Research methodology; Social research; Open source; Online community; Open-source software; Risk; mailing lists; online data; Virtual community; Threat; Cooperation; Internet; Social networks; Reliability; Virtual Reality; Social Sciences: Comprehensive Works; article; Property; 0104:methodology and research technology; Choices; Methodology (Data Collection); observation; observer roles; open source software communities; research methods/tools","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open- source software projects and provide clear implications for the structure of future open-source communities.","2016-04-27","2025-03-25 19:20:35","2025-03-25 19:20:35","2025-03-25 19:20:35","13:1–13:29","","2","25","","","Inflow and Retention in OSS Communities with Commercial Involvement","","","","","","","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/LB62LWCB/Zhou et al. - 2016 - Inflow and Retention in OSS Communities with Comme.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The primary difficulty is that software development efforts are complex in terms of both the technical and social aspects of the engineering environment. This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data. For four of the five project success measures, the results indicate that the developed model represents the underlying data well and provides accurate predictions of open source project success indicators.","2009-05-18","2025-03-25 19:27:34","2025-03-25 19:27:34","2025-03-25","1–8","","","","","","","PROMISE '09","","","","Association for Computing Machinery","New York, NY, USA","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/5BSRU2DK/Beaver et al. - 2009 - Modeling success in FLOSS project groups.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper proposed Bayesian Network to construct the structure of interoperability and then learn the condition probability table of the structure.

It is unclear what role these peripheral developers play in the programming and communication efforts, as well as the temporary task-related sub-groups in the projects. We mine code-repository data and mailing-list discussions to model the relationships and contributions of developers in a social network and devise a method to analyze the temporal collaboration structures in communication and programming, learning about the strength and stability of social sub-groups in open-source software projects. Our method uses multi-modal social networks on a series of time windows. Previous work has reduced the network structure representing developer collaboration to networks with only one type of interaction, which impedes the simultaneous analysis of more than one type of interaction. We use both communication and version-control data of open-source software projects and model different types of interaction over time. To demonstrate the practicability of our measurement and analysis method, we investigate 10 substantial and popular open-source software projects and show that, if sub-groups evolve, modeling these sub-groups helps predict the future evolution of interaction levels of programmers and groups of developers.

In addition, we measured their self-efficacy before and after their participation. We found that what drove participants were intrinsic motivations, altruism, and internal values, which differed from previous work with older adults and with the general FOSS population. We also found that self-efficacy did not change significantly, even when participants encountered significant barriers or setbacks. The top 3 barriers were lack of communication, installation issues, and documentation issues. We found that asking for and receiving help, and avoiding difficult development environments were more likely to lead to success.

We have found that several OSS systems appear not to obey some of ""Lehman's laws"" of software evolution [5, 7], and that Linux in particular is continuing to grow at a geometric rate. Currently, we are working on a detailed study of the evolution of one of the subsystems of the Linux kernel: the SCSI drivers subsystem. We have found that cloning, which is usually considered to be an indicator of lazy development and poor process, is quite common and is even considered to be a useful practice.Second, we are developing a tool called Beagle to aid software maintainers in understanding how large systems have changed over time. Beagle integrates data from various static analysis and metrics tools and provides a query engine as well as navigable visualizations.

The paper summarizes our preliminary investigations into the evolution of the best known open source system: the Linux operating system kernel. Because Linux is large (over two million lines of code in the most recent version) and because its development model is not as tightly planned and managed as most industrial software processes, we had expected to find that Linux was growing more slowly as it got bigger and more complex. Instead, we have found that Linux has been growing at a super-linear rate for several years. The authors explore the evolution of the Linux kernel both at the system level and within the major subsystems, and they discuss why they think Linux continues to exhibit such strong growth.","2000-10","2025-03-26 14:59:22","2025-03-26 14:59:34","2025-03-26 14:59:22","131-142","","","","","","Evolution in open source software","","","","","","","","","","","","IEEE Xplore","","ISSN: 1063-6773","","/Users/mgone/Zotero/storage/URA3N8YR/Godfrey and Tu - 2000 - Evolution in open source software a case study.pdf; /Users/mgone/Zotero/storage/7PDU9NFR/883030.html","","","Software prototyping","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","Proceedings 2000 International Conference on Software Maintenance","","","","","","","","","","","","","","",""

This is especially important for ""infrastructure"" projects, such as critical libraries and programming languages that many other people depend on. Some projects have taken the approach of borrowing planning tools that originated in commercial development, despite the fact that these techniques were designed for very different contexts, e.g. strong top-down control and profit motives. Little research has been done to understand how these practices are adapted to a new context. In this paper, we examine the Rust project's use of roadmaps: how has an important OSS infrastructure project adapted an inherently top-down tool to the freewheeling world of OSS? We find that because Rust's roadmaps are built in part by summarizing what motivated developers most prefer to work on, they are in some ways more a description of the motivated labor available than they are a directive that the community move in a particular direction. They allow the community to avoid wasting time on unpopular proposals by revealing that there will be little help in building them, and encouraging work on popular features by making visible the amount of consensus in those features. Roadmaps generate a collective focus without limiting the full scope of what developers work on: roadmap issues consume proportionally more effort than other issues, but constitute a minority of the work done (i.e issues and pull requests made) by both central and peripheral participants. They also create transparency among and beyond the community into what central contributors' plans are, and allow more rational decision-making by providing a way for evidence about community needs to be linked to decision-making.","2021-04-22","2025-02-27 03:08:35","2025-03-26 15:45:04","2025-03-26 15:44:56","158:1–158:28","","CSCW1","5","","","""They Can Only Ever Guide""","","","","","","","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/4QFZHAYR/Klug et al. - 2021 - They Can Only Ever Guide How an Open Source Sof.pdf","","open source; collaboration; common pool resources; rust language","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system’s sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries. Specifically, we leveraged a weighted combination of semantics, lexical, and shallow features in conjunction with the Random Forest ensemble learning method. Finally, we discuss the practical applicability of our classifier for mapping and visualizing quality-related concerns into the codebase with an example from the Derby project. To summarize, this work represents an effort and an early awareness to improve the underlying management of issue tracking systems and stakeholder requirements in open-source communities.","2021-03","2025-03-26 15:54:43","2025-03-26 15:55:52","2025-03-26 15:54:43","12-23","","","","","","","","","","","","","","","","","","IEEE Xplore","","ISSN: 1534-5351","","/Users/mgone/Zotero/storage/YZNHDGGL/9425929.html; /Users/mgone/Zotero/storage/EUZWJWEF/Krasniqi and Agrawal - 2021 - Analyzing and Detecting Emerging Quality-Related C.pdf","","","Maintenance engineering; Tools; Visualization; Security; Semantics; Stakeholders; Computer bugs; Bug Reports; Issue Tracking Systems; Lexical Features; Quality Concerns; Semantic Features; Shallow Features","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","2021 IEEE International Conference on Software Analysis, Evolution and Reengineering (SANER)","","","","","","","","","","","","","","",""

The developers' sentiment in this process can have an impact on their working willingness and efficiency. Monitoring sentiment factors can help to improve OSS development and management. However, no method has been proposed to dynamically monitor the sentiment phenomena during the OSS development process. In this paper, an approach to detect Negative Sentiment-related Events (NSE) is proposed. It consists of two steps. The first step is to identify the burst interval of negative comments from open source projects, which corresponds to a NSE. The second step is to annotate this NSE with its event type.

This paper investigates developer collaboration networks in three OSS communities by data analytics. The results indicate that real networks are mainly characterized by the modular small-world structure, which is inherently correlated with the sub-project participation of developers. Most module members are single-dimensional developers whose coding-collaboration focuses on a small number of sub-projects (called the main dimension of the module), while a small proportion of module members are multi-dimensional developers who conduct coding-collaboration in the main dimension of different modules. These results may deepen our understandings of the collaborative pattern of OSS communities, and also have some reference value for the studies of open collaborative innovation in large-scale crowds.","2021-09-28","2025-02-27 03:09:13","2025-03-26 16:02:24","2025-03-26","84–91","","","","","","","DSIT 2021","","","","Association for Computing Machinery","New York, NY, USA","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/8ZTYM7Q7/Liu and Gui - 2021 - Structural Analysis of Collaboration Network in OS.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine the two peer review techniques used by the successful, mature Apache server project: review-then-commit and commit-then-review. Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects. We provide a comparison of the two Apache review techniques as well as a comparison of Apache review to inspection in an industrial project.

A primary reason for OSS project failure is the shock caused by the dropout of a core developer, which can jeopardize productivity and project survival. Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer. Our findings underscore the importance of a balanced approach in OSS project management, harmonizing productivity goals with resilience considerations.","2024-05-13","2025-02-27 03:09:15","2025-03-26 19:31:47","2025-03-26","706–709","","","","","","","WWW '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/TUY9EL3G/Russo Latona et al. - 2024 - Shock!

In this research, we look at FLOSS developers' relationships in terms of positive evaluations given by others. Using this perspective, we examine how FLOSS developers' reputation among members within and beyond the project community affects their projects' ability to attract new developers. We draw on Social Resource Theory (SRT) and hypothesize that developers with a high reputation among others enjoy high visibility and credibility, which in turn helps their projects to attract new members. Finally, we propose an evaluation approach for our research model that examines the reputation and project behavior of more than 1,000 FLOSS developers on a longitudinal base.","2014-05-29","2025-03-26 19:57:14","2025-03-26 19:57:22","2025-03-26","5–10","","","","","","Stars matter","SIGSIM-CPR '14","","","","Association for Computing Machinery","New York, NY, USA","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/X9DP8XHT/Schilling et al. - 2014 - Stars matter how FLOSS developers' reputation aff.pdf","","open source software development; attraction; free libre open source software; reputation; social resource theory","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The success of an open source software development (OSSD) community is often attributed to the underlying governance model, and a key component of these models is the decision-making (DM) process. While there have been studies on the decision-making processes publicized by OSS communities (e.g., through published process diagrams), little has been done to study decision-making processes that can be extracted using a bottom-up, data-driven approach, which can then be used to assess whether the publicized processes conform to the extracted processes. To bridge this gap, we undertook a large-scale data-driven study to understand how decisions are made in an OSSD community, using the case study of Python Enhancement Proposals (PEPs), which embody decisions made during the evolution of the Python language. Our main contributions are:(a) the design and development of a framework using information retrieval and natural language processing techniques to analyze the Python email archives (comprising 1.48 million emails), and(b) the extraction of decision-making processes that reveal activities that are neither explicitly mentioned in documentation published by the Python community nor identified in prior research work.

In contrast, research on the corresponding “receiving” side of the innovation process is scarce. We address this gap, studying how existing OSS code is reused and serves as an input to further OSS development. Our findings are based on a survey with 686 responses from OSS developers. As the most interesting results, our multivariate analyses of developers’ code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early - as the “credible promise” in OSS - leads to increased reuse. Finally, we identify developers’ interest to tackle difficult technical challenges as detrimental to efficient reuse-based innovation. Beyond OSS, we discuss the relevance of our findings for companies developing software and for the receiving side of open innovation processes in general.","2010-03-09","2025-03-26 20:05:28","2025-03-26 20:05:54","2025-03-26 20:05:28","","","","","","","Code Reuse in Open Source Software Development","","","","","","","en","","","","","papers.ssrn.com","","","","/Users/mgone/Zotero/storage/C7QMV3NE/Sojer and Henkel - 2010 - Code Reuse in Open Source Software Development Qu.pdf","","","Innovation; Software Development; Open Source Software; Code Reuse","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.","2015","2025-02-27 03:11:36","2025-03-26 20:07:25","2025-03-26 20:07:13","224-237","","1","26","","","Research Note","","","","","","","","","","","","JSTOR","","Publisher: INFORMS","","/Users/mgone/Zotero/storage/45AZPGEK/Spaeth et al. - 2015 - Research Note Perceived Firm Attributes and Intri.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Typically, the developers create a stable branch for each old stable version, deploy security patches on the branch, and release fixed versions at regular intervals. As such, old-version applications in production environments are protected from the disclosed vulnerabilities in a long time. However, the rapidly growing number of OSS vulnerabilities has greatly strained this patch deployment model, and a critical need has arisen for the security community to understand the practice of security patch management across stable branches. In this work, we conduct a large-scale empirical study of stable branches in OSS projects and the security patches deployed on them via investigating 608 stable branches belonging to 26 popular OSS projects as well as more than 2,000 security fixes for 806 CVEs deployed on stable branches. Our study distills several important findings: (i) more than 80% affected CVE-Branch pairs are unpatched; (ii) the unpatched vulnerabilities could pose a serious security risk to applications in use, with 47.39% of them achieving a CVSS score over 7 (High or Critical Severity); and (iii) the patch porting process requires great manual efforts and takes an average of 40.46 days, significantly extending the time window for N-day vulnerability attacks. Our results reveal the worrying state of security patch management across stable branches.

In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.","2025-03","2025-04-08 17:20:04","2025-04-08 17:20:04","","4","","1","33","","","","","","","","","","English","","","ABI/INFORM Global","3145911815","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Quality+enhancement+in+OSS+development+process%3A+a+quantitative+framework+approach&rft.au=.&rft.aulast=&rft.aufirst=&rft.date=2025-03-01&rft.volume=33&rft.issue=1&rft.spage=4&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-024-09705-0","Open source software; GitHub; Software quality; Resource allocation; Computers--Software; Source code; Decision analysis; Comparative analysis; Quality assessment; Operations research; Quantitative analysis; Multiple criteria decision making; Development process; Multi-criteria decision analysis; Multiple criterion; Project feasibility; Version control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-08 17:20:06","2025-04-08 17:20:06","","1449-1469","","4","63","","","","","","","","","","English","","","ABI/INFORM Global","3129871390","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Small+Business+Economics&rft.atitle=Financing+A+Free-for-All%3A+Crowdfunding+Open-Source+Software&rft.au=Bort%2C+James%3BMeoli%2C+Azzurra%3BSullivan%2C+David+W..&rft.aulast=Bort&rft.aufirst=James&rft.date=2024-12-01&rft.volume=63&rft.issue=4&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Small+Business+Economics&rft.issn=0921898X&rft_id=info:doi/10.1007%2Fs11187-023-00867-y","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business And Economics--Small Business; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-08 17:20:06","2025-04-08 17:20:06","","361","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","2783221355","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Resilience+in+the+Open+Source+Software+Community%3A+How+Pandemic+and+Unemployment+Shocks+Influence+Contributions+to+Others%27+and+One%27s+Own+Projects&rft.au=Malgonde%2C+Onkar+S%3BSaldanha%2C+Terence+J+V%3BMithas%2C+Sunil.&rft.aulast=Malgonde&rft.aufirst=Onkar&rft.date=2023-03-01&rft.volume=47&rft.issue=1&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2022%2F17256","Open source software; COVID-19; Computers; Resilience; Pandemics; Public health; Community; Open source; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Nature conservation; Resource conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023","2025-04-08 17:20:06","2025-04-08 17:20:06","","3106-3130","","5","49","","","","","","","","","","English","","","ABI/INFORM Global","2814541650","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Understanding+Mentors%26rsquo%3B+Engagement+in+OSS+Communities+via+Google+Summer+of+Code&rft.au=Tan%2C+Xin%3BZhou%2C+Minghui%3BZhang%2C+Li.&rft.aulast=Tan&rft.aufirst=Xin&rft.date=2023-01-01&rft.volume=49&rft.issue=5&rft.spage=3106&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2023.3242415","Open source software; Organizations; Mentors; Motivation; Data analysis; Students; Open-source software; Task analysis; Strategy; Mentoring; Sustainability; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; Computers--Software; taxonomy; Challenge; mentoring process; Mentorship; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success.

The purpose of this paper is to analyse the teachers’ motivation to contribute to OSS projects for teaching. A structural equation model (SEM) has been defined under the postulates of the Path-Goal leadership theory and Motivational Behaviour. This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader. Second, this study finds that motivating the participants of a project – teachers in this case – is highly recommended, in order to reach a successful adoption of OSS solutions for education.","2022-12","2025-04-08 17:20:06","2025-04-08 17:20:06","","1449-1463","","12","34","","","","","","","","","","English","","","ABI/INFORM Global","2731285764","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Analysis+%26+Strategic+Management&rft.atitle=The+impact+of+leadership+styles+and+motivations%3A+lessons+from+Open+Source+Software+projects+for+educational+organizations&rft.au=Racero%2C+F+Jos%C3%A9%3BBueno%2C+Salvador%3BGallego%2C+M+Dolores.&rft.aulast=Racero&rft.aufirst=F&rft.date=2022-12-01&rft.volume=34&rft.issue=12&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Technology+Analysis+%26+Strategic+Management&rft.issn=09537325&rft_id=info:doi/10.1080%2F09537325.2021.1963698","Open source software; Leadership; Motivation; motivations; Software; Open-source software; Intrinsic motivation; Open Source Software; Context; leadership; Education; teachers; Public domain; Leadership style; Multivariate statistical analysis; Structural equation modeling; Teachers; Teaching; Technology: Comprehensive Works; Transactional leadership; Transformational leadership","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust→CCBs and the CCBs→Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust→CCBs relationship. These findings are explained from several theoretical perspectives, which provide directions for future research and help community management to maintain sustained participation.","2022-09","2025-04-08 17:20:06","2025-04-08 17:20:06","","907-920","","5","62","","","","","","","","","","English","","","ABI/INFORM Global","2708632042","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Sustained+Participation+in+Open+Source+Software+Project+Communities&rft.au=Shi%2C+Zhengzhong%3BSun%2C+Hua.&rft.aulast=Shi&rft.aufirst=Zhengzhong&rft.date=2022-09-01&rft.volume=62&rft.issue=5&rft.spage=907&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2021.1949645","Open source software; Computers; Data analysis; Open source; Participation; Hypotheses; OSS; Software; diffusion of innovation; Trust; Public domain; Software project management; Qualitative analysis; Community participation; integrative model of trust; intellectual capital creation; social learning system; stage model; sustained participation; vector autoregressive model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022-01","2025-04-08 17:20:07","2025-04-08 17:20:07","","165-195","","1","23","","","","","","","","","","English","","","ABI/INFORM Global","2619733915","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/Ydh4M?_a=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&_s=zHoOSQHC7zGSY1Lrj1y6C2ajqNs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=A+Motivation-Hygiene+Model+of+Open+Source+Software+Code+Contribution+and+Growth&rft.au=Sharma%2C+Pratyush+Nidhi%3BDaniel%2C+Sherae+L%3BTingting+%28Rachel%29+Chung%3BGrover%2C+Varun.&rft.aulast=Sharma&rft.aufirst=Pratyush&rft.date=2022-01-01&rft.volume=23&rft.issue=1&rft.spage=165&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00712","Open source software; Motivation; Information systems; Growth; Open source; Software; Open-source software; Computers--Information Science And Information Theory; Public domain; Source code; Growth models; A Motivation-Hygiene Model of Open Source Software Code Contribution and Growth; Computer program; Hygiene","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the differential impacts of such social influence on developers' initial and sustained participation behaviors were largely overlooked in previous research. We empirically studied the impacts of two social influence mechanisms—word‐of‐mouth (WOM) and observational learning (OL)—on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.","2021-09","2025-04-08 17:20:07","2025-04-08 17:20:07","","1133-1147","","9","72","","","","","","","","","","English","","","ABI/INFORM Global","2558095618","","","Place: Hoboken Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Science+and+Technology&rft.atitle=Differential+impacts+of+social+influence+on+initial+and+sustained+participation+in+open+source+software+projects&rft.au=Yang%2C+Xuan%3BLi%2C+Xiao%3BHu%2C+Daning%3BWang%2C+Harry+Jiannan.&rft.aulast=Yang&rft.aufirst=Xuan&rft.date=2021-09-01&rft.volume=72&rft.issue=9&rft.spage=1133&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Science+and+Technology&rft.issn=23301635&rft_id=info:doi/10.1002%2Fasi.24481","Open source software; Learning; Platforms; Library And Information Sciences; Social research; Open source; Software; Open-source software; Social influence; Social Influences; Social networks; Software development; Public domain; Software Projects; Software development tools; Modeling (Psychology); Observational Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-08 17:20:07","2025-04-08 17:20:07","","8","","","49","","","","","","","","","","English","","","ABI/INFORM Global","2582094786","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/x0MyK?_a=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&_s=%2FlTTM3bDFac2N1veyo77qKjQ6No%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Episodic+Peripheral+Contributors+and+Technical+Dependencies+in+Open+Source+Software+%28OSS%29+Ecosystems&rft.au=Moon%2C+Eunyoung.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2021-01-01&rft.volume=49&rft.issue=&rft.spage=8&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04908","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been institutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous security in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed security controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption enables businesses to deliver time-to-market security ready applications and services with accelerated velocity and sustainable agility in a cost-effective way.","2020-10","2025-04-08 17:20:07","2025-04-08 17:20:07","","1-28","","","97","","","","","","","","","","English","","","ABI/INFORM Global","2454359046","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Computers+%26+Security&rft.atitle=Modeling+continuous+security%3A+A+conceptual+model+for+automated+DevSecOps+using+open-source+software+over+cloud+%28ADOC%29&rft.au=Kumar%2C+Rakesh%3BGoyal%2C+Rinkaj.&rft.aulast=Kumar&rft.aufirst=Rakesh&rft.date=2020-10-01&rft.volume=97&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Computers+%26+Security&rft.issn=01674048&rft_id=info:doi/10.1016%2Fj.cose.2020.101967","Open source software; Cloud computing; Automation; Security; Business; Cybersecurity; Software development; Assurance; Public domain; Economic; Computers--Electronic Data Processing; Codification; Workflow; Applications programs; Business process; DevOps; Performance measurement; Security controls","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-08 17:20:07","2025-04-08 17:20:07","","1439","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2447305472","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Takeoff+of+Open+Source+Software%3A+A+Signaling+Perspective+Based+on+Community+Activities&rft.au=Setia%2C+Pankaj%3BBayus%2C+Barry+L%3BRajagopalan%2C+Balaji.&rft.aulast=Setia&rft.aufirst=Pankaj&rft.date=2020-09-01&rft.volume=44&rft.issue=3&rft.spage=1439&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F12576","Open source software; Computers; Open source; Software; Open-source software; Signaling; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for‐profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-08 17:20:07","2025-04-08 17:20:07","","369-402","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2352536913","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+Third+Design+Space%3A+A+postcolonial+perspective+on+corporate+engagement+with+open+source+software+communities&rft.au=Kendall%2C+Kenneth+E%3BKendall%2C+Julie+E%3BGermonprez%2C+Matt%3BMathiassen%2C+Lars.&rft.aulast=Kendall&rft.aufirst=Kenneth&rft.date=2020-03-01&rft.volume=30&rft.issue=2&rft.spage=369&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12270","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Computers--Computer Systems; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-08 17:20:07","2025-04-08 17:20:07","","20","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2500501225","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/JGBVI?_a=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&_s=ZwMsI0CRPDfS%2Fx12%2Fam7rwPvXL8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Decision-making+Processes+in+Community-based+Free%2FLibre+Open+Source+Software-development+Teams+with+Internal+Governance%3A+An+Extension+to+Decision-making+Theory&rft.au=Eseryel%2C+U+Yeliz%3BKangning+Wei%3BCrowston%2C+Kevin.&rft.aulast=Eseryel&rft.aufirst=U&rft.date=2020-01-01&rft.volume=46&rft.issue=&rft.spage=20&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04620","Open source software; Decision making; Computers--Information Science And Information Theory; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-08 17:20:07","2025-04-08 17:20:07","","764","","3","30","","","","","","","","","","English","","","ABI/INFORM Global","2307721543","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Does+Superposition+Influence+the+Success+of+FLOSS+Projects%3F+An+Examination+of+Open-Source+Software+Development+by+Organizations+and+Individuals&rft.au=Medappa%2C+Poonacha+K%3BSrivastava%2C+Shirish+C.&rft.aulast=Medappa&rft.aufirst=Poonacha&rft.date=2019-09-01&rft.volume=30&rft.issue=3&rft.spage=764&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2018.0829","Open source software; Organizations; Motivation; Open source; Software engineering; Open-source software; Computer architecture; Ownership; Success; Computers--Information Science And Information Theory; Project management; Software development; Freeware; 51821:Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services; Modular design; Project Success; Superposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, a modified non-homogeneous Poisson process model is developed in an imperfect debugging environment by assuming that new faults may be introduced in fault detection and correction process. Then, the detection rate and remaining faults of previous release are considered in the modeling and analysis of reliability of the current release. The optimal version-update time is computed using multi-attribute utility theory for these software systems, considering the two main utility factors, namely, rapid release strategy and level of reliability. The proposed models are verified on real data sets and are compared with other existing models.

Only a few empirical studies investigate how the choice of components is conducted in industrial practice. This is important to understand to tailor research solutions to the needs of the industry. Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better.

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS. Cependant, ces recherches se sontprincipalement concentrées sur des projets reconnus et de grande envergure, tels que Linux ou Apache. Une investigation des projets moins connus permettrait une compréhension plus complete et d'éviter un taux d'échec important des projets OSS. Cette étude investigue donc la combi- naison de trois facteurs : les interactions des utilisateurs et développeurs, la pénétration du marché et le stade de développement, afin d'observer leur impact sur la popularité des projets OSSpeu connus. Nous a vons pour cela développé un modele empirique de la popularité des OSS, et avons testé nos hypotheses sur 657projets de logiciel libre. Les résultats de cette recherche montrent que la combinaison des trois facteurs a un impact positif sur la popularité des OSS. De plus, contrairement aux études précédentes, nos résultats révelent également que les interactions entre utilisateurs et développeurs ont un rôle plus important que les activités reliées á la résolution de bugs dans la réussite des projets. Cette recherche propose une nouvelle maniere de mesurer la popularité d'un projet OSS et offrant ainsi aux organisations une meilleure compréhension.","2017-10","2025-04-08 17:20:07","2025-04-08 17:20:07","","47-74,117","","3","22","","","","","","","","","","English","","","ABI/INFORM Global","1969517670","","","Place: Paris Publisher: Editions ESKA","","; ","https://media.proquest.com/media/hms/PFT/1/g3eZ3?_a=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&_s=TDPmpbTuX3nLSv9pl2dBP8w0%2F4M%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Syst%C3%A8mes+d%27Information+et+Management&rft.atitle=OSS+popularity%3A+Understanding+the+relationship+between+user-developer+interaction%2C+market+potential+and+development+stage&rft.au=Cheruy%2C+Cl%C3%A9mence%3BRobert%2C+Frank%3BBelbaly%2C+Nassim.&rft.aulast=Cheruy&rft.aufirst=Cl%C3%A9mence&rft.date=2017-10-01&rft.volume=22&rft.issue=3&rft.spage=47&rft.isbn=&rft.btitle=&rft.title=Syst%C3%A8mes+d%27Information+et+Management&rft.issn=12604984&rft_id=info:doi/","Open source software; Information systems; Business And Economics--Management; Hypotheses; Open-source software; Linux; Success; Social; Social networks; Software quality; Public domain; Freeware; Business metrics; Developer; Investigations; Management science; Market penetration; Market potential; Popularity; User services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume – suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017","2025-04-08 17:20:07","2025-04-08 17:20:07","","43-66","","2","29","","","","","","","","","","English","","","ABI/INFORM Global","2866855510","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/wC7YX?_a=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&_s=AH2MYk0kmnJKLtLEtVIDIizdS%2Bw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+and+End+User+Computing&rft.atitle=Developers%2C+Quality+Control+and+Download+Volume+in+Open+Source+Software+%28OSS%29+Projects&rft.au=Hill%2C+Geoffrey%3BDatta%2C+Pratim%3BCandice+Vander+Weerdt.&rft.aulast=Hill&rft.aufirst=Geoffrey&rft.date=2017-04-01&rft.volume=29&rft.issue=2&rft.spage=43&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+and+End+User+Computing&rft.issn=15462234&rft_id=info:doi/10.4018%2FJOEUC.2017040103","Open source software; Open source; Software; Open-source software; Open Source Software; Quality control; Segmented Regression; Software development; Computers--Electronic Data Processing; Developer Limit; Downloading; Quality Control; Quality Control Index; Regression Discontinuity; Tragedy of the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While a large body of studies focuses on the importance of developers' reputations in their participation motivations, there is still lack of understanding for two issues. First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

In this research, we advance on such studies through an integrated FLOSS evaluation-selection model with a risk-based decision-making approach. Our model was built upon the other two literatures, and it was structured as a multi-attribute decision-making (MADM) model which contains 12 variables grouped in four risk categories: financial, organisational, end user, and technical ones. We illustrated its utilisation in the domain of information technology service management (ITSM) FLOSS tools.

Passive users play a critical role in the adoption and diffusion of OSS, and we need more research to understand their behaviors and motivations. We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.","2015-08","2025-04-08 17:20:08","2025-04-08 17:20:08","","674-706","","8","16","","","","","","","","","","English","","","ABI/INFORM Global","1711618000","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/OBJ/QFcWV?_a=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%3D%3D&_s=NukQhHdoSs7AKmjonN2p29jHjz0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Loyalty%2C+Ideology%2C+and+Identification%3A+An+Empirical+Study+of+the+Attitudes+and+Behaviors+of+Passive+Users+of+Open+Source+Software&rft.au=Choi%2C+Namjoo%3BChengalur-Smith%2C+Indushobha%3BNevo%2C+Saggi.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-08-01&rft.volume=16&rft.issue=8&rft.spage=674&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Sociology; Identification; Information systems; Community; Studies; User behavior; Marketing; Virtual communities; Open source; Hypotheses; Open-source software; Consumer behavior; Research; Success; Computers--Information Science And Information Theory; Software development; Loyalty; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; 7100:Market research; Consciousness; Ideology; Usability testing; User","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project’s time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project’s progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-08 17:20:08","2025-04-08 17:20:08","","116","","1","32","","","","","","","","","","English","","","ABI/INFORM Global","1697517813","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+Information+Systems&rft.atitle=Exploitation+and+Exploration+Networks+in+Open+Source+Software+Development%3A+An+Artifact-Level+Analysis%3A+JMIS&rft.au=Temizkan%2C+Orcun%3BKumar%2C+Ram+L.&rft.aulast=Temizkan&rft.aufirst=Orcun&rft.date=2015-07-01&rft.volume=32&rft.issue=1&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+Information+Systems&rft.issn=07421222&rft_id=info:doi/","Open source software; Political Science; Studies; Open source; Software engineering; Software; Open-source software; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-08 17:20:08","2025-04-08 17:20:08","","119-139","","1","39","","","","","","","","","","English","","","ABI/INFORM Global","1655249846","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/Q0uKV?_a=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&_s=c3Lp6TqythFY%2BWrN%2BTvJkpa1pVs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=Raising+the+general+public%27s+awareness+and+adoption+of+open+source+software+through+social+Q%26amp%3BA+interactions&rft.au=Choi%2C+Namjoo%3BYi%2C+Kwan.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-01-01&rft.volume=39&rft.issue=1&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/","Open source software; Motivation; Qualitative research; Studies; Computers--Internet; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1,409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. They also reproduced the results on new data provided by Mozilla. The authors constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-08 17:20:08","2025-04-08 17:20:08","","127-143","","2","39","","","","","","","","","","English","","","ABI/INFORM Global","1929783648","","","Place: Ahmedabad Publisher: Sage Publications, New Delhi India","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Vikalpa&rft.atitle=The+Emergence+of+an+Organizational+Field%3A+The+Case+of+Open+Source+Software&rft.au=Ojha%2C+Abhoy+K%3BRao%2C+Ravi+Anand.&rft.aulast=Ojha&rft.aufirst=Abhoy&rft.date=2014-04-01&rft.volume=39&rft.issue=2&rft.spage=127&rft.isbn=&rft.btitle=&rft.title=Vikalpa&rft.issn=02560909&rft_id=info:doi/10.1177%2F0256090920140211","Open source software; Business And Economics--Management; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them. Several implications for research and practice, and directions for future research are provided.","2014","2025-04-08 17:20:08","2025-04-08 17:20:08","","260-275","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","1660948775","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/bsfLV?_a=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&_s=zrtihhrjnuKV9%2BUVmos5%2B4c%2Bllg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+application+profiles+and+development+characteristics+of+library+Open+Source+Software+projects&rft.au=Choi%2C+Namjoo.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2014-04-01&rft.volume=32&rft.issue=2&rft.spage=260&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2FLHT-09-2013-0127","Open source software; Community; Research methodology; Studies; Open source; Libraries; Open-source software; Licenses; Success; Data collection; Software development; Programming languages; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; Library And Information Sciences--Computer Applications; 51921:Libraries and Archives; Academic libraries; Institutional repositories; Archival description; Datasets; Integrated library systems--ILS; Integrated library systems-ILS; Internet resources","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-08 17:20:08","2025-04-08 17:20:08","","477-512","","4","34","","","","","","","","","","English","","","ABI/INFORM Global","1510748443","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/7E55V?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yPWuXs0jr4o83q1fDVJWcSjQgII%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=International+Journal+of+Operations+%26+Production+Management&rft.atitle=Risk+of+adopting+mission-critical+OSS+applications%3A+an+interpretive+case+study&rft.au=Poba-Nzaou%2C+Placide%3BRaymond%2C+Louis%3BFabi%2C+Bruno.&rft.aulast=Poba-Nzaou&rft.aufirst=Placide&rft.date=2014-04-01&rft.volume=34&rft.issue=4&rft.spage=477&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Operations+%26+Production+Management&rft.issn=01443577&rft_id=info:doi/10.1108%2FIJOPM-03-2012-0117","Open source software; Information technology; Business And Economics--Management; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

We hypothesize that when an IPR enforcement action is filed, user interest and developer activity will be negatively affected in two types of related OSS projects - those that display technology overlap with the OSS application in dispute and business projects that are specific to the disputed OSS platform. We examine two widely publicized lawsuits-SCO v. IBM and FireStar/DataTern v. Red Hat-using data from SourceForge.net. Our difference-in-difference estimates show that in the months following the filing of SCO v. IBM, OSS projects that exhibit high technology overlap with the disputed OSS experienced a 15% greater decline in user interest and 45% less developer activity than projects in the control group; OSS projects that are intended for business and specific to the disputed OSS platform had a 34% greater decline in user interest and 86% less developer activity than the control group. We find similar results following the filing of FireStar/DataTern v. Red Hat. Our results are also robust to a variety of robustness checks, including a falsification exercise and subsample analyses.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated 'copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the 'new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11","2025-04-08 17:20:09","2025-04-08 17:20:09","","597-625","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2089824849","","","Place: Abingdon Publisher: Taylor & Francis LLC","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Free software; Property; Capitalism; Economic theory; Free and open-source software; Profitability; Profits; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One reason for this is project stagnation after developers quit their projects. This fact has motivated researchers to examine the factors that influence developers' intention to continue their participation. One factor is trust among developers. The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey. Our findings indicate that cooperative norms and effective communication engender trust, whereas an accreditation mechanism eliminates distrust. Additionally, trust positively influences their intention to continue participating, whereas distrust negatively influences it.

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the ""virtuous circle"" supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other. Each of these findings is related to the sustainability of these projects.","2013-01","2025-04-08 17:20:09","2025-04-08 17:20:09","","13-19","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473072","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/r92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=w1JsQafjriUDvJXmxD%2Fvc6puLsw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=Sustainability+in+Open+Source+Software+Commons%3A+Lessons+Learned+from+an+Empirical+Study+of+SourceForge+Projects&rft.au=Schweik%2C+Charles+M.&rft.aulast=Schweik&rft.aufirst=Charles&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=13&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; institutional analysis; Collective action; Business And Economics; Collaboration; Open source; open source software; Hypotheses; Open-source software; Research; Success; commons; Sustainable development; Sustainability; Public domain; Software Projects; Programmers; Books; Variables; Information commons; internet-based collaboration; SourceForge","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-08 17:20:09","2025-04-08 17:20:09","","32-39","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473053","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/y42HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=2t9cyrsjrGTKotUlU5ETuqoVg%2F4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=The+Evolving+Role+of+Open+Source+Software+in+Medicine+and+Health+Services&rft.au=Ingram%2C+David%3BSevket+Seref+Arikan.&rft.aulast=Ingram&rft.aufirst=David&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Research & development--R&D; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-08 17:20:09","2025-04-08 17:20:09","","28-36","","12","2","","","","","","","","","","English","","","ABI/INFORM Global","1614473125","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/Z92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=GbZFrwogPCXpMB86F2AnR11z97U%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=An+Enterprise+Perspective+on+Customer+Value+Propositions+for+Open+Source+Software&rft.au=Shanker%2C+Aparna.&rft.aulast=Shanker&rft.aufirst=Aparna&rft.date=2012-12-01&rft.volume=2&rft.issue=12&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help ""transfer"" their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

Yet many unanswered questions exist regarding why certain FOSS projects succeed while others fail. Drawing on social capital theory and human agency theory, this study proposes that FOSS projects stand a better chance of success if they possess desirable social network capital and adopt effective strategies. It further argues that valuable social network capital and effective strategies produce greater returns together than they do alone. The results of an empirical analysis reveal significant positive interactions between social capital variables and human agency/strategy variables, highlighting the importance of complementarity between social network ties and strategies in shaping the outcome of FOSS projects.

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS.

By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net.

OSS projects evolve and transform over time; therefore success must be examined longitudinally over a period of time. In this research, we examine two measures of project success: project popularity and developer activity, of 283 OSS projects over a span of 3 years, in order to observe changes over time. A comprehensive research model of OSS success is developed which includes both extrinsic and intrinsic attributes. Results show that while many of the hypothesized relationships are supported, there were marked differences in some of the relationships at different points in time lending support to the notion that different factors need to be emphasized as the OSS project unfolds over time.

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-08 17:20:10","2025-04-08 17:20:10","","156-187","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1018105738","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/wxbVU?_a=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%3D%3D&_s=X0oQ4nOZDi9uA5E9tyFKZJTP08c%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Information+Technology+%26+People&rft.atitle=Adoption+of+free%2Flibre+open+source+software+in+public+organizations%3A+factors+of+impact&rft.au=Rossi%2C+Bruno%3BRusso%2C+Barbara%3BSucci%2C+Giancarlo.&rft.aulast=Rossi&rft.aufirst=Bruno&rft.date=2012-04-01&rft.volume=25&rft.issue=2&rft.spage=156&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593841211232677","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Technology; Case studies; Technology adoption; Migration; Adoption; Case study; 5240:Software & systems; Public domain; Innovations; Public sector; 9130:Experimental/theoretical; Open standards; Cost control; Business process re-engineering; Disruptive innovation; Environmental factor; Library And Information Sciences--Computer Applications; Software services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

So it was important to reassess the factors enabling OSS adoption in order to enhance OSS utilization within public sector organisations. This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-08 17:20:10","2025-04-08 17:20:10","","","","2","17","","","","","","","","","","English","","","ABI/INFORM Global","2546081220","","","Place: Wollongong Publisher: Australasian Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/na1qJ?_a=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%3D%3D&_s=N0WDCOWv2H3E1ddURTiZTg8qVwo%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Australasian+Journal+of+Information+Systems&rft.atitle=Enablers+of+Open+Source+Software+adoption%3A+A+case+study+of+APS+organisations&rft.au=Gurusamy%2C+Kavitha%3BCampbell%2C+John.&rft.aulast=Gurusamy&rft.aufirst=Kavitha&rft.date=2012-01-01&rft.volume=17&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Australasian+Journal+of+Information+Systems&rft.issn=14498618&rft_id=info:doi/10.3127%2Fajis.v17i2.731","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Computers--Computer Systems; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

This phenomenon is also known as ""Inner Source"". While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Following an initial systematic literature review to generate seed category data constructs, the authors performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques.","2011-12","2025-04-08 17:20:10","2025-04-08 17:20:10","","1319","","12","53","","","","","","","","","","English","","","ABI/INFORM Global","894730546","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=A+comparative+study+of+challenges+in+integrating+Open+Source+Software+and+Inner+Source+Software&rft.au=Stol%2C+Klaas-Jan%3BBabar%2C+Muhammad+Ali%3BAvgeriou%2C+Paris%3BFitzgerald%2C+Brian.&rft.aulast=Stol&rft.aufirst=Klaas-Jan&rft.date=2011-12-01&rft.volume=53&rft.issue=12&rft.spage=1319&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Open source; Software engineering; Software; Open-source software; Software development; 5240:Software & systems; Public domain; Systems development; Computers--Data Base Management; 9130:Experimental/theoretical; Systems integration; Comparative studies; Inner source; System integration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ''joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

OSS development takes online community as its organizational form, and developers voluntarily work for the project. In the project execution process, control aligns individual behaviors toward the organizational goals via the Internet and becomes critical to the success of OSS projects. This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community. The study contributes to a better understanding of OSS project organizations and processes, and provides advice for OSS development.","2011","2025-04-08 17:20:10","2025-04-08 17:20:10","","26-42","","1","22","","","","","","","","","","English","","","ABI/INFORM Global","2954642973","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/FF6YX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=6d%2Bi6am9M1LDqVW0E%2Fp1TGT7Yvg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=A+Study+of+Open+Source+Software+Development+from+Control+Perspective&rft.au=Lin%2C+Zhangxi%3BXu%2C+Bo%3BXu%2C+Yan.&rft.aulast=Lin&rft.aufirst=Zhangxi&rft.date=2011-01-01&rft.volume=22&rft.issue=1&rft.spage=26&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2011010102","Open source software; Open source; Software Development; Software; Open-source software; Software development; Control; Open Source Software (OSS); Software industry; Computers--Data Base Management; Industrial development; Open; OSS Development; Outcome; Project Management; Self-control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Behind a successful oss project lies a community of actors, ranging from core developers to passive users, held together by a flexible governance structure and membership, leadership and contribution policies that align their interests. The motivation behind individuals participating in oss projects can be, among others, social, ideological, hedonistic, or signaling, while companies gain from their access to high-quality, innovative projects and an increase in their reputation and visibility. Nowadays many business models rely on oss as a product through the provision of associated services, or in coexistence with proprietary software, hardware, services, or licensing. The numerous oss licenses mainly differ on how they treat derived software: some contain provisions that maintain its availability in open source form while others allow more flexibility. Through its widespread adoption, oss is affecting the software industry, science, engineering, research, teaching, the developing countries, and the society at large through its ability to democratize technology and innovation.","2011","2025-04-08 17:20:10","2025-04-08 17:20:10","","187-347","","3-4","4","","","","","","","","","","English","","","ABI/INFORM Global","2695489045","","","Place: Hanover Publisher: Now Publishers Inc","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.atitle=Open+Source+Software%3A+A+Survey+from+10%2C000+Feet&rft.au=Androutsellis-Theotokis%2C+Stephanos%3BSpinellis%2C+Diomidis%3BKechagia%2C+Maria%3BGousios%2C+Georgios.&rft.aulast=Androutsellis-Theotokis&rft.aufirst=Stephanos&rft.date=2011-01-01&rft.volume=4&rft.issue=3-4&rft.spage=187&rft.isbn=&rft.btitle=&rft.title=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.issn=15719545&rft_id=info:doi/10.1561%2F0200000026","Open source software; Leadership; Information systems; Open source; Software engineering; Software license; Software; Open-source software; Psychology; Operations management; Computers--Information Science And Information Theory; Information management; Software development; Public domain; Freeware; Source code; Developing countries--LDCs; Software distribution; Proprietary software; Engineering education; Licensing (technology); Software licenses; Visibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

HFOSS also integrates two volunteer-rich communities that have much in common: the humanitarian community and the open source community.

Recently, the focus has shifted toward an examination of a newer construct -temporal dispersion (TD). The study of TD so far has been constrained mostly to conceptual work. This study furthers the understanding of TD through an empirical investigation of its relationship with open source software (OSS) team performance. In this paper, hypotheses are developed based on coordination theory, and analyses are performed using data collected from multiple archival sources comprising 100 OSS development teams. Results indicate that TD positively affects development speed and quality and that software complexity moderates the relation between TD and software quality. Theoretical and practical implications are discussed.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-08 17:20:11","2025-04-08 17:20:11","","656","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","196420145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Using+the+DEMO+methodology+for+modeling+open+source+software+development+processes&rft.au=Huysmans%2C+Philip%3BVen%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Huysmans&rft.aufirst=Philip&rft.date=2010-06-01&rft.volume=52&rft.issue=6&rft.spage=656&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Computers--Data Base Management; Ontology; Demo; Process modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and tribal knowledge that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-08 17:20:11","2025-04-08 17:20:11","","211-223","","2","28","","","","","","","","","","English","","","ABI/INFORM Global","521142269","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/qPQuT?_a=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&_s=R3D%2FTgQI5szaHaGdFb%2BVEn%2FrVUA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+economy+of+free+and+open+source+software+in+the+preservation+of+digital+artefacts&rft.au=Morrissey%2C+Sheila.&rft.aulast=Morrissey&rft.aufirst=Sheila&rft.date=2010-04-01&rft.volume=28&rft.issue=2&rft.spage=211&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2F07378831011047622","Open source software; Studies; Open source; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Library And Information Sciences--Computer Applications; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article, we examine change in cognitive complexity and its impacts on maintenance in the context of open source software (OSS). Relationships of the change in cognitive complexity with the change in the number of reported bugs, time taken to fix the bugs, and contributions from new developers are examined and are all found to be statistically significant. In addition, several control variables, such as software size, age, development status, and programmer skills are included in the analyses. The results have strong implications for OSS project administrators; they must continually measure software complexity and be actively involved in managing it in order to have successful and sustainable OSS products.

Our analysis draws on a large sample of projects registered at Sourceforge.net, the world's largest incubator of open source software activity. We test the hypothesis that skill variety of participants is associated with project performance. We also explore whether the level of modularization of project activities is correlated with performance. Our econometric estimations show that skill heterogeneity is associated with project survival and performance. However, the relationship between skill diversity and performance is non-monotonic. Design modularity is also positively associated with the performance of the project. Finally, the interaction between skill heterogeneity and modularity is negatively associated with performance.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.

While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

The main results are that if Norden-Rayleigh-based approaches are used, they need to be complemented in order to account for the addition of new features during a product life cycle, and that programmer-participation based effort models result in distinctly lower estimations of effort than those based on output metrics, such as lines of code.

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-08 17:20:12","2025-04-08 17:20:12","","449-462","","5","16","","","","","","","","","","English","","","ABI/INFORM Global","212365312","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/b6OaT?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yiXUHeA3Bd5m9qlApbZJ63Be1aM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Management+%26+Computer+Security&rft.atitle=Evaluating+the+performance+of+open+source+software+projects+using+data+envelopment+analysis&rft.au=Wray%2C+Barry%3BMathieu%2C+Richard.&rft.aulast=Wray&rft.aufirst=Barry&rft.date=2008-10-20&rft.volume=16&rft.issue=5&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Information+Management+%26+Computer+Security&rft.issn=09685227&rft_id=info:doi/10.1108%2F09685220810920530","Open source software; Studies; Productivity; Business And Economics--Management; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-08 17:20:12","2025-04-08 17:20:12","","142-156","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","211770348","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aQ4UT?_a=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&_s=skz%2By9xiJklpExxCBn8Dys3vIXk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Innovation+Management&rft.atitle=Online+innovation%3A+the+case+of+open+source+software+development&rft.au=Vujovic%2C+Sladjana%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=Vujovic&rft.aufirst=Sladjana&rft.date=2008-01-01&rft.volume=11&rft.issue=1&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Innovation+Management&rft.issn=14601060&rft_id=info:doi/10.1108%2F14601060810845268","Open source software; Innovation; Communication; Information technology; Studies; Business And Economics--Management; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Public domain; Technological change; Innovations; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Following a case study methodology, we examined developer interaction data from three active and successful FLOSS projects using qualitative research methods, specifically inductive content analysis, to identify the task-assignment mechanisms used by the participants. We found that 'self-assignment' was the most common mechanism across three FLOSS projects. This mechanism is consistent with expectations for distributed and largely volunteer teams.

Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

Under what conditions can it be employed in other contexts? ""Collective invention"" regimes usually ended when a dominant design emerged. This is not the case with OSS. Firstly, the OSS community developed the institutional innovation of OSS licenses enabling OSS software to survive as a common property. Secondly, these licenses are mainly enforced by pro-socially motivated contributors. We characterize the conditions under which OSS communities develop and sustain pro-social commitments. We point out the vulnerability of these conditions to developments in patent legislation.

Little attention has been paid to individuals who spend valuable time in lists helping participants on some mundane yet vital project activities. Using three Debian lists as a case study we investigate the impact of knowledge brokers and their associated activities in open source projects. Social network analysis was used to visualize how participants are affiliated with the lists. The network topology reveals substantial community participation. The consequence of collaborating in mundane activities for the success of open source software projects is discussed. The direct beneficiaries of this research are in the identification of knowledge experts in open source software projects.

This survey-based study, conducted with 402 active LUG members representing 191 different LUGs from 23 countries and employing structural equation modeling methodology, supports the proposed model. Furthermore, we find that the Linux user's experience level moderates the extent of the LUG's social influence and its impact on the user's participation.

This paper develops and tests a model of the impacts of license restrictiveness and organizational sponsorship on two indicators of success: user interest in, and development activity on, open source software development projects. Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.

MBSD takes advantage of the OMG MDA (model-driven architecture) technology. The system architecture of MBSD and its operation and implementation are presented.

Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied - especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-08 17:20:13","2025-04-08 17:20:13","","227-238","","2","44","","","","","","","","","","English","","","ABI/INFORM Global","222420968","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/ORIG/5/G0cEE?_a=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&_s=SVgzekDe95rQdVHfJ2Zo%2BltJgw0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Systems+Journal&rft.atitle=The+value+of+open+standards+and+open-source+software+in+government+environments&rft.au=Simon%2C+K+D.&rft.aulast=Simon&rft.aufirst=K&rft.date=2005-04-01&rft.volume=44&rft.issue=2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=IBM+Systems+Journal&rft.issn=00188670&rft_id=info:doi/","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-08 17:20:13","2025-04-08 17:20:13","","","","2","48","","","","","","","","","","English","","","ABI/INFORM Global","237056523","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Open+source+software+for+medical+image+processing+and+visualization&rft.au=Yoo%2C+Terry+S%3BAckerman%2C+Michael+J.&rft.aulast=Yoo&rft.aufirst=Terry&rft.date=2005-02-01&rft.volume=48&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/10.1145%2F1042091.1042120","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Research & development--R&D; United States--US; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Computers--Data Communications And Data Transmission Systems; Digital image processing; Image; Medical imaging","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This observation, however, has not been discussed in much detail and critically addressed by the software engineering community. Most of the claims associated with open source appear to be weakly motivated and articulated. For this reason, this paper proposes some qualitative reflections and observations on the nature of open source software and on the most popular and important claims associated with the open source approach. The ultimate goal of the paper is to identify the concepts and intuitions that are really peculiar to open source, and to distinguish them from features and aspects that can be equally applied to or found in proprietary software.

This research investigates the evolution of open source software using a case study of the Samba project. Through the application of both qualitative and quantitative techniques, Samba's software development and evolution over a seven-year period are tracked and assessed. This assessment and the findings of similar, previously reported studies lead us to propose a general framework for the evolution and the key drivers of open source software evolution.

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-08 17:20:13","2025-04-08 17:20:13","","94-112","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","821692253","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/8v97U?_a=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&_s=pUsDcFs3MVZkPLVZxMuyqK90UPQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Open+source+software+and+software+patents%3A+A+constitutional+perspective&rft.au=Pfaffenberger%2C+Bryan.&rft.aulast=Pfaffenberger&rft.aufirst=Bryan&rft.date=1999-10-01&rft.volume=12&rft.issue=3&rft.spage=94&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-999-1029-x","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-08 17:20:50","2025-04-08 17:38:18","","1449-1469","","4","63","","","","","","","","","","English","","","ABI/INFORM Global","3129871390","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Small+Business+Economics&rft.atitle=Financing+A+Free-for-All%3A+Crowdfunding+Open-Source+Software&rft.au=Bort%2C+James%3BMeoli%2C+Azzurra%3BSullivan%2C+David+W..&rft.aulast=Bort&rft.aufirst=James&rft.date=2024-12-01&rft.volume=63&rft.issue=4&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Small+Business+Economics&rft.issn=0921898X&rft_id=info:doi/10.1007%2Fs11187-023-00867-y","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business And Economics--Small Business; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores activities that contribute to the long-term well-being of public-sector FOSS ecosystems, focusing on public-sector entities as orchestrators and keystone players. A qualitative multi-case study of three ecosystems was conducted, with data collected through interviews, participant observation, and analysis of online discussion forums. The study presents a model for health-sustaining activities in public-sector FOSS ecosystems. Orchestrators and keystone players are found to engage in health-sustaining activities through rulemaking, role creation, and tool provision, hinting at the explanatory potential of Activity Theory. Furthermore, the study identifies key challenges in orchestrating public sector FOSS ecosystems, such as institutional misalignment and conflicting policy frameworks, highlighting these as critical areas for future research.","2024","2025-04-08 17:20:50","2025-04-08 17:20:50","","","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","3152500844","","","Place: Aalborg Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/lP17b?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=CbtWqrxs3u%2BJGoCCoKC1Vx6zM30%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Scandinavian+Journal+of+Information+Systems&rft.atitle=Health+and+Orchestration+of+Public-Sector+Open-Source+Software+Ecosystems+Roles%2C+rules+and+tools&rft.au=Henttonen%2C+Katja+M%3BPulkkinen%2C+Mirja%3BTyrvainen%2C+Pasi.&rft.aulast=Henttonen&rft.aufirst=Katja&rft.date=2024-01-01&rft.volume=36&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Scandinavian+Journal+of+Information+Systems&rft.issn=09050167&rft_id=info:doi/","Open source software; governance; FOSS; Computers; Free software; open-source software; software ecosystem; Public domain; ecosystem health; Misalignment; orchestration; Players; public sector; Public sector; Qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the authors develop a set of hypotheses based on the knowledge barriers framework that examines how OSS communities can encourage contributions from newcomers.Design/methodology/approachEmploying longitudinal data from the source code repositories of 232 OSS projects over a two-year period, the authors employ a Poisson-based mixed model to test how community characteristics, such as the main drivers of knowledge-based costs, relate to newcomers' contributions.FindingsThe results indicate that community characteristics, such as programming language choice, documentation effort and code structure instability, are the main drivers of knowledge-based contribution costs. The findings also suggest that managing these costs can result in more inclusive OSS communities, as evidenced by the number of contributing newcomers; the authors highlight the importance of maintaining documentation efforts for OSS communities.Originality/valueThis paper assumes that motivational factors are a necessary but insufficient condition for newcomer participation in OSS projects and that the cost to participation should be considered.

To the best of the authors' knowledge, this is the first empirical study that does not limit data collection to a single hosting platform (e.g., SourceForge), which improves the generalizability of the findings.","2024","2025-04-08 17:20:50","2025-04-08 17:32:43","","665-689","","3","34","","","","","","","","","","English","","","ABI/INFORM Global","3056990363","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","/Users/mgone/Zotero/storage/UPE898SZ/AlMarzouq et al. - 2024 - An empirical examination of newcomer contribution .pdf; ; ","https://media.proquest.com/media/hms/PFT/1/P8yWY?_a=ChgyMDI1MDQwODE3MTAxNjg4ODo5MzA4NjESBTk5OTQxGgpPTkVfU0VBUkNIIg4xNjUuMTI0Ljg1LjEyOSoFNDY4OTYyCjMwNTY5OTAzNjM6DURvY3VtZW50SW1hZ2VCATBSBk9ubGluZVoCRlRiA1BGVGoKMjAyNC8wMS8wMXIKMjAyNC8xMi8zMXoAggElUC0xMDAwMDAxLTEyODYxLUNVU1RPTUVSLW51bGwtMTE0NDQwMpIBBk9ubGluZcoBVE1vemlsbGEvNS4wIChNYWNpbnRvc2g7IEludGVsIE1hYyBPUyBYIDEwLjE1OyBydjoxMzcuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC8xMzcuMNIBElNjaG9sYXJseSBKb3VybmFsc5oCB1ByZVBhaWSqAitPUzpFTVMtTWVkaWFMaW5rc1NlcnZpY2UtZ2V0TWVkaWFVcmxGb3JJdGVtygIPQXJ0aWNsZXxGZWF0dXJl0gIBWfICAPoCAU6CAwNXZWKKAxxDSUQ6MjAyNTA0MDgxNzEwMTY4ODg6Mjg3MDUw&_s=H8xbI7qc%2B7%2BbgltWyGELYBVrCd0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Internet+Research&rft.atitle=An+empirical+examination+of+newcomer+contribution+costs+in+established+OSS+communities%3A+a%26nbsp%3Bknowledge-based+perspective&rft.au=AlMarzouq%2C+Mohammad%3BGrover%2C+Varun%3BThatcher%2C+Jason%3BKlein%2C+Rich.&rft.aulast=AlMarzouq&rft.aufirst=Mohammad&rft.date=2024-01-01&rft.volume=34&rft.issue=3&rft.spage=665&rft.isbn=&rft.btitle=&rft.title=Internet+Research&rft.issn=10662243&rft_id=info:doi/10.1108%2FINTR-08-2022-0594","Newcomers; Open source software; Innovation; Computers--Internet; Participation; OSS; Data Collection; Knowledge sharing; Sustainability; Data collection; Documentation; Costs; Programming languages; Mixed-methods; Source code; Impact fees; Community Action; Community Relations; Congruence (Psychology); Coordination costs; Knowledge barriers; Knowledge Level; Learning costs; Learning Processes; Software projects; Trust (Psychology)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace. Using stakeholder theory, we identified stakeholder groups within a single OSS project to demonstrate their distinct interests and how these interests influence their value creation activities over time.

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-08 17:20:50","2025-04-08 17:55:54","","361","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","2783221355","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","; /Users/mgone/Zotero/storage/U6MJWPZX/Malgonde et al. - 2023 - Resilience in the Open Source Software Community .pdf","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Resilience+in+the+Open+Source+Software+Community%3A+How+Pandemic+and+Unemployment+Shocks+Influence+Contributions+to+Others%27+and+One%27s+Own+Projects&rft.au=Malgonde%2C+Onkar+S%3BSaldanha%2C+Terence+J+V%3BMithas%2C+Sunil.&rft.aulast=Malgonde&rft.aufirst=Onkar&rft.date=2023-03-01&rft.volume=47&rft.issue=1&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2022%2F17256","Open source software; COVID-19; Computers; pandemic; Resilience; Pandemics; Public health; Community; unemployment; Open source; open source software; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Open source software community; Nature conservation; Resource conservation; digital resilience; exogenous shock; IT knowledge workers; IT professionals","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023","2025-04-08 17:20:51","2025-04-08 18:01:48","","3106-3130","","5","49","","","","","","","","","","English","","","ABI/INFORM Global","2814541650","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Understanding+Mentors%26rsquo%3B+Engagement+in+OSS+Communities+via+Google+Summer+of+Code&rft.au=Tan%2C+Xin%3BZhou%2C+Minghui%3BZhang%2C+Li.&rft.aulast=Tan&rft.aufirst=Xin&rft.date=2023-01-01&rft.volume=49&rft.issue=5&rft.spage=3106&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2023.3242415","Open source software; Organizations; Mentors; Motivation; Data analysis; Students; Open-source software; Task analysis; Strategy; Mentoring; Sustainability; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; Computers--Software; taxonomy; Challenge; mentoring process; Mentorship; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers’ early careers and hence shed light on future research in this direction.","2023","2025-04-08 17:20:51","2025-04-08 19:00:55","","529-548","","2","49","","","","","","","","","","English","","","ABI/INFORM Global","2776777604","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Off+to+a+Good+Start%3A+Dynamic+Contribution+Patterns+and+Technical+Success+in+an+OSS+Newcomer%26rsquo%3Bs+Early+Career&rft.au=Yang%2C+Yue%3BWang%2C+Yi%3BRedmiles%2C+David.&rft.aulast=Yang&rft.aufirst=Yue&rft.date=2023-01-01&rft.volume=49&rft.issue=2&rft.spage=529&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2022.3156071","Careers; open source; Task analysis; Ecosystems; Success; Documentation; Engineering profession; Codes; Correlation; Newcomer; Focusing; Statistical analysis; Computers--Software; Empirical analysis; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A structural equation model (SEM) has been defined under the postulates of the Path-Goal leadership theory and Motivational Behaviour. This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader.

With the lens of the integrative model of trust (IMoT), hypotheses regarding interactions between trust and community citizenship behaviors (CCBs – as OSSPC participating activities) are developed. Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust→CCBs and the CCBs→Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust→CCBs relationship. These findings are explained from several theoretical perspectives, which provide directions for future research and help community management to maintain sustained participation.","2022-09","2025-04-08 17:20:51","2025-04-08 17:57:23","","907-920","","5","62","","","","","","","","","","English","","","ABI/INFORM Global","2708632042","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Sustained+Participation+in+Open+Source+Software+Project+Communities&rft.au=Shi%2C+Zhengzhong%3BSun%2C+Hua.&rft.aulast=Shi&rft.aufirst=Zhengzhong&rft.date=2022-09-01&rft.volume=62&rft.issue=5&rft.spage=907&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2021.1949645","Open source software; Computers; Data analysis; Open source; Participation; Hypotheses; OSS; Software; diffusion of innovation; Trust; Public domain; Software project management; Qualitative analysis; Community participation; integrative model of trust; intellectual capital creation; social learning system; stage model; sustained participation; vector autoregressive model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022-01","2025-04-08 17:20:51","2025-04-08 17:30:27","","165-195","","1","23","","","","","","","","","","English","","","ABI/INFORM Global","2619733915","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/Ydh4M?_a=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&_s=zHoOSQHC7zGSY1Lrj1y6C2ajqNs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=A+Motivation-Hygiene+Model+of+Open+Source+Software+Code+Contribution+and+Growth&rft.au=Sharma%2C+Pratyush+Nidhi%3BDaniel%2C+Sherae+L%3BTingting+%28Rachel%29+Chung%3BGrover%2C+Varun.&rft.aulast=Sharma&rft.aufirst=Pratyush&rft.date=2022-01-01&rft.volume=23&rft.issue=1&rft.spage=165&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00712","Open source software; Motivation; Information systems; Growth; Open source; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Public domain; Source code; Growth models; A Motivation-Hygiene Model of Open Source Software Code Contribution and Growth; Computer program; Hygiene; Change Over Time; Code Contribution; Multilevel Growth Analysis; Payment; Value Fit","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-08 17:20:51","2025-04-08 17:37:22","","8","","","49","","","","","","","","","","English","","","ABI/INFORM Global","2582094786","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/x0MyK?_a=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&_s=%2FlTTM3bDFac2N1veyo77qKjQ6No%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Episodic+Peripheral+Contributors+and+Technical+Dependencies+in+Open+Source+Software+%28OSS%29+Ecosystems&rft.au=Moon%2C+Eunyoung.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2021-01-01&rft.volume=49&rft.issue=&rft.spage=8&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04908","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A myriad of Open Source Software (OSS) projects are available in the community for this purpose, however, many companies may remain reluctant to adopt them as the cornerstone for their new evolved systems that can work at scale. Ownership, security, quality concerns, or support confidence are widely common reasons. Furthermore, these concerns are intensified when the OSS is to take part in critical sections of the evolved system. Using a complex case study from Zalando, this article aims to give some light to both researchers and practitioners into the use of OSS to drive this evolution, and the impact that the OSS can have on the adopting system.","2021","2025-04-08 17:20:51","2025-04-08 17:54:08","","34-41","","1","23","","","","","","","","","","English","","","ABI/INFORM Global","2483254650","","","Place: Washington Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IT+Professional+Magazine&rft.atitle=Open+Source+Software+as+the+Main+Driver+for+Evolving+Software+Systems+Toward+a+Distributed+and+Performant+E-Commerce+Platform%3A+A+Zalando+Fashion+Store+Case+Study&rft.au=Vera-Baquero%2C+Alejandro%3BPhelan%2C+Owen%3BSlowinski%2C+Pawel%3BHannon%2C+John.&rft.aulast=Vera-Baquero&rft.aufirst=Alejandro&rft.date=2021-01-01&rft.volume=23&rft.issue=1&rft.spage=34&rft.isbn=&rft.btitle=&rft.title=IT+Professional+Magazine&rft.issn=15209202&rft_id=info:doi/10.1109%2FMITP.2020.2994993","Open source software; Productivity; Software; Open-source software; Computer architecture; Evolution; Case studies; Estimation; Reliability; Reliability engineering; Distributed computing; Public domain; Engineering; Software system; Elasticity; Microservices","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-08 17:20:52","2025-04-08 17:59:07","","1439","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2447305472","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Takeoff+of+Open+Source+Software%3A+A+Signaling+Perspective+Based+on+Community+Activities&rft.au=Setia%2C+Pankaj%3BBayus%2C+Barry+L%3BRajagopalan%2C+Balaji.&rft.aulast=Setia&rft.aufirst=Pankaj&rft.date=2020-09-01&rft.volume=44&rft.issue=3&rft.spage=1439&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F12576","Open source software; Computers; Open source; Software; Open-source software; Signaling; product quality; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff; signaling; takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for‐profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-08 17:20:52","2025-04-08 17:59:12","","369-402","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2352536913","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+Third+Design+Space%3A+A+postcolonial+perspective+on+corporate+engagement+with+open+source+software+communities&rft.au=Kendall%2C+Kenneth+E%3BKendall%2C+Julie+E%3BGermonprez%2C+Matt%3BMathiassen%2C+Lars.&rft.aulast=Kendall&rft.aufirst=Kenneth&rft.date=2020-03-01&rft.volume=30&rft.issue=2&rft.spage=369&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12270","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Computers--Computer Systems; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-08 17:20:52","2025-04-08 17:35:44","","20","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2500501225","","","Place: Atlanta Publisher: Association for Information Systems","","; /Users/mgone/Zotero/storage/K8DFKNBG/Eseryel et al. - 2020 - Decision-making Processes in Community-based Free.pdf; ","https://media.proquest.com/media/hms/PFT/1/JGBVI?_a=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&_s=ZwMsI0CRPDfS%2Fx12%2Fam7rwPvXL8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Decision-making+Processes+in+Community-based+Free%2FLibre+Open+Source+Software-development+Teams+with+Internal+Governance%3A+An+Extension+to+Decision-making+Theory&rft.au=Eseryel%2C+U+Yeliz%3BKangning+Wei%3BCrowston%2C+Kevin.&rft.aulast=Eseryel&rft.aufirst=U&rft.date=2020-01-01&rft.volume=46&rft.issue=&rft.spage=20&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04620","Open source software; Decision making; OSS; Decision Making; Computers--Information Science And Information Theory; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution; Decision Process; F/LOSS; Free/Libre Open Source Software Development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While about half of respondents confirmed using OSS, the authors found surprisingly low levels of intent to adopt from current non-adopters.Practical implicationsThis research offers insights for promoting OSS adoption. Also, it provides funding agencies and administrators with guidelines to encourage successful deployment of OSS in higher education.Originality/valueWhile extant research is mostly anecdotal, this research draws from an online survey to snap-shot the current state of OSS adoption in US academic libraries and provides a baseline for practice and research.","2019","2025-04-08 17:20:52","2025-04-08 17:57:59","","641-659","","4","37","","","","","","","","","","English","","","ABI/INFORM Global","2308435090","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/DsyOJ?_a=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&_s=uVzfcu7K0PQpsfHIgCgr2uOWIGc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+context+and+state+of+open+source+software+adoption+in+US+academic+libraries&rft.au=Choi%2C+Namjoo%3BPruett%2C+Joseph+A.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2019-10-01&rft.volume=37&rft.issue=4&rft.spage=641&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2FLHT-02-2019-0042","Open source software; Higher education; Data analysis; Open source; Software; Libraries; Open-source software; Usability; Research; Case studies; Technology adoption; Software quality; Public domain; Proprietary; United States--US; Cost control; Developing countries--LDCs; Library And Information Sciences--Computer Applications; 51921:Libraries and Archives; Barrier; Academic libraries; Institutional repositories; Library; Integrated library systems-ILS; Internet resources; Survey; Academic library; Driver; Electronic resources management; Information technology adoption; University libraries; USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-08 17:20:52","2025-04-08 17:36:45","","764","","3","30","","","","","","","","","","English","","","ABI/INFORM Global","2307721543","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Does+Superposition+Influence+the+Success+of+FLOSS+Projects%3F+An+Examination+of+Open-Source+Software+Development+by+Organizations+and+Individuals&rft.au=Medappa%2C+Poonacha+K%3BSrivastava%2C+Shirish+C.&rft.aulast=Medappa&rft.aufirst=Poonacha&rft.date=2019-09-01&rft.volume=30&rft.issue=3&rft.spage=764&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2018.0829","Open source software; Organizations; Motivation; collaboration; motivation; Open source; econometrics; Software engineering; Open-source software; Computer architecture; Ownership; Success; Computers--Information Science And Information Theory; virtual teams; Project management; open-source software; Software development; Freeware; 51821:Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services; Modular design; Project Success; Superposition; information systems (IS) development; project success; superposition; task structure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, a modified non-homogeneous Poisson process model is developed in an imperfect debugging environment by assuming that new faults may be introduced in fault detection and correction process. Then, the detection rate and remaining faults of previous release are considered in the modeling and analysis of reliability of the current release. The optimal version-update time is computed using multi-attribute utility theory for these software systems, considering the two main utility factors, namely, rapid release strategy and level of reliability. The proposed models are verified on real data sets and are compared with other existing models.

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS. Cependant, ces recherches se sontprincipalement concentrées sur des projets reconnus et de grande envergure, tels que Linux ou Apache. Une investigation des projets moins connus permettrait une compréhension plus complete et d'éviter un taux d'échec important des projets OSS. Cette étude investigue donc la combi- naison de trois facteurs : les interactions des utilisateurs et développeurs, la pénétration du marché et le stade de développement, afin d'observer leur impact sur la popularité des projets OSSpeu connus. Nous a vons pour cela développé un modele empirique de la popularité des OSS, et avons testé nos hypotheses sur 657projets de logiciel libre.

We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.","2015-08","2025-04-08 17:20:53","2025-04-08 17:20:53","","674-706","","8","16","","","","","","","","","","English","","","ABI/INFORM Global","1711618000","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/OBJ/QFcWV?_a=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%3D%3D&_s=NukQhHdoSs7AKmjonN2p29jHjz0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Loyalty%2C+Ideology%2C+and+Identification%3A+An+Empirical+Study+of+the+Attitudes+and+Behaviors+of+Passive+Users+of+Open+Source+Software&rft.au=Choi%2C+Namjoo%3BChengalur-Smith%2C+Indushobha%3BNevo%2C+Saggi.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-08-01&rft.volume=16&rft.issue=8&rft.spage=674&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Sociology; Identification; Information systems; Community; Studies; User behavior; Marketing; Virtual communities; Open source; Hypotheses; Open-source software; Consumer behavior; Research; Success; Computers--Information Science And Information Theory; Software development; Loyalty; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; 7100:Market research; Consciousness; Ideology; Usability testing; User","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-08 17:20:53","2025-04-08 17:38:02","","116","","1","32","","","","","","","","","","English","","","ABI/INFORM Global","1697517813","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+Information+Systems&rft.atitle=Exploitation+and+Exploration+Networks+in+Open+Source+Software+Development%3A+An+Artifact-Level+Analysis%3A+JMIS&rft.au=Temizkan%2C+Orcun%3BKumar%2C+Ram+L.&rft.aulast=Temizkan&rft.aufirst=Orcun&rft.date=2015-07-01&rft.volume=32&rft.issue=1&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+Information+Systems&rft.issn=07421222&rft_id=info:doi/","Open source software; social networks; Political Science; Studies; Open source; software development; open source software development; Software engineering; Software; Open-source software; team formation; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration; project success; exploitation and exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-08 17:20:53","2025-04-08 17:55:29","","119-139","","1","39","","","","","","","","","","English","","","ABI/INFORM Global","1655249846","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/Q0uKV?_a=ChgyMDI1MDQwODE3MTAxNjg4ODo5MzA4NjESBTk5OTQxGgpPTkVfU0VBUkNIIg4xNjUuMTI0Ljg1LjEyOSoFMjcxNjMyCjE2NTUyNDk4NDY6DURvY3VtZW50SW1hZ2VCATBSBk9ubGluZVoCRlRiA1BGVGoKMjAxNS8wMS8wMXIKMjAxNS8wMi8xNHoAggElUC0xMDAwMDAxLTEyODYxLUNVU1RPTUVSLW51bGwtMTE0NDQwMpIBBk9ubGluZcoBVE1vemlsbGEvNS4wIChNYWNpbnRvc2g7IEludGVsIE1hYyBPUyBYIDEwLjE1OyBydjoxMzcuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC8xMzcuMNIBElNjaG9sYXJseSBKb3VybmFsc5oCB1ByZVBhaWSqAitPUzpFTVMtTWVkaWFMaW5rc1NlcnZpY2UtZ2V0TWVkaWFVcmxGb3JJdGVtygIPQXJ0aWNsZXxGZWF0dXJl0gIBWfICAPoCAU6CAwNXZWKKAxxDSUQ6MjAyNTA0MDgxNzEwMTY4ODg6Mjg3MDUw&_s=c3Lp6TqythFY%2BWrN%2BTvJkpa1pVs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=Raising+the+general+public%27s+awareness+and+adoption+of+open+source+software+through+social+Q%26amp%3BA+interactions&rft.au=Choi%2C+Namjoo%3BYi%2C+Kwan.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-01-01&rft.volume=39&rft.issue=1&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/","Open source software; Motivation; Qualitative research; Studies; Computers--Internet; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. They also reproduced the results on new data provided by Mozilla. The authors constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-08 17:20:53","2025-04-08 17:20:53","","127-143","","2","39","","","","","","","","","","English","","","ABI/INFORM Global","1929783648","","","Place: Ahmedabad Publisher: Sage Publications, New Delhi India","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Vikalpa&rft.atitle=The+Emergence+of+an+Organizational+Field%3A+The+Case+of+Open+Source+Software&rft.au=Ojha%2C+Abhoy+K%3BRao%2C+Ravi+Anand.&rft.aulast=Ojha&rft.aufirst=Abhoy&rft.date=2014-04-01&rft.volume=39&rft.issue=2&rft.spage=127&rft.isbn=&rft.btitle=&rft.title=Vikalpa&rft.issn=02560909&rft_id=info:doi/10.1177%2F0256090920140211","Open source software; Business And Economics--Management; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment.

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-08 17:20:54","2025-04-08 17:56:07","","477-512","","4","34","","","","","","","","","","English","","","ABI/INFORM Global","1510748443","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/7E55V?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yPWuXs0jr4o83q1fDVJWcSjQgII%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=International+Journal+of+Operations+%26+Production+Management&rft.atitle=Risk+of+adopting+mission-critical+OSS+applications%3A+an+interpretive+case+study&rft.au=Poba-Nzaou%2C+Placide%3BRaymond%2C+Louis%3BFabi%2C+Bruno.&rft.aulast=Poba-Nzaou&rft.aufirst=Placide&rft.date=2014-04-01&rft.volume=34&rft.issue=4&rft.spage=477&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Operations+%26+Production+Management&rft.issn=01443577&rft_id=info:doi/10.1108%2FIJOPM-03-2012-0117","Open source software; Information technology; Business And Economics--Management; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical; IT adoption; IT risk management; SME","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

We hypothesize that when an IPR enforcement action is filed, user interest and developer activity will be negatively affected in two types of related OSS projects - those that display technology overlap with the OSS application in dispute and business projects that are specific to the disputed OSS platform. We examine two widely publicized lawsuits-SCO v. IBM and FireStar/DataTern v. Red Hat-using data from SourceForge.net. Our difference-in-difference estimates show that in the months following the filing of SCO v. IBM, OSS projects that exhibit high technology overlap with the disputed OSS experienced a 15% greater decline in user interest and 45% less developer activity than projects in the control group; OSS projects that are intended for business and specific to the disputed OSS platform had a 34% greater decline in user interest and 86% less developer activity than the control group. We find similar results following the filing of FireStar/DataTern v. Red Hat. Our results are also robust to a variety of robustness checks, including a falsification exercise and subsample analyses.

One reason for this is project stagnation after developers quit their projects. This fact has motivated researchers to examine the factors that influence developers' intention to continue their participation. One factor is trust among developers. The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey. Our findings indicate that cooperative norms and effective communication engender trust, whereas an accreditation mechanism eliminates distrust. Additionally, trust positively influences their intention to continue participating, whereas distrust negatively influences it.

Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the ""virtuous circle"" supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other. Each of these findings is related to the sustainability of these projects.","2013-01","2025-04-08 17:20:54","2025-04-08 17:57:15","","13-19","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473072","","","Place: Ottawa Publisher: Talent First Network","","; ; /Users/mgone/Zotero/storage/RP3K73YJ/Schweik - 2013 - Sustainability in Open Source Software Commons Le.pdf","https://media.proquest.com/media/hms/OBJ/r92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=w1JsQafjriUDvJXmxD%2Fvc6puLsw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=Sustainability+in+Open+Source+Software+Commons%3A+Lessons+Learned+from+an+Empirical+Study+of+SourceForge+Projects&rft.au=Schweik%2C+Charles+M.&rft.aulast=Schweik&rft.aufirst=Charles&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=13&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; institutional analysis; Collective action; Business And Economics; Collaboration; Open source; open source software; Hypotheses; Open-source software; Research; Success; commons; Sustainable development; Sustainability; Public domain; Software Projects; Programmers; Books; Variables; Information commons; internet-based collaboration; SourceForge","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-08 17:20:54","2025-04-08 17:58:26","","32-39","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473053","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/y42HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=2t9cyrsjrGTKotUlU5ETuqoVg%2F4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=The+Evolving+Role+of+Open+Source+Software+in+Medicine+and+Health+Services&rft.au=Ingram%2C+David%3BSevket+Seref+Arikan.&rft.aulast=Ingram&rft.aufirst=David&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Research & development--R&D; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-08 17:20:55","2025-04-08 17:32:53","","28-36","","12","2","","","","","","","","","","English","","","ABI/INFORM Global","1614473125","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/Z92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=GbZFrwogPCXpMB86F2AnR11z97U%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=An+Enterprise+Perspective+on+Customer+Value+Propositions+for+Open+Source+Software&rft.au=Shanker%2C+Aparna.&rft.aulast=Shanker&rft.aufirst=Aparna&rft.date=2012-12-01&rft.volume=2&rft.issue=12&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help ""transfer"" their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

Yet many unanswered questions exist regarding why certain FOSS projects succeed while others fail. Drawing on social capital theory and human agency theory, this study proposes that FOSS projects stand a better chance of success if they possess desirable social network capital and adopt effective strategies. It further argues that valuable social network capital and effective strategies produce greater returns together than they do alone. The results of an empirical analysis reveal significant positive interactions between social capital variables and human agency/strategy variables, highlighting the importance of complementarity between social network ties and strategies in shaping the outcome of FOSS projects.

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS.

By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.","2012-04","2025-04-08 17:20:55","2025-04-08 17:38:43","","920","","4","85","","","","","","","","","","English","","","ABI/INFORM Global","925777279","","","Place: New York Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Systems+and+Software&rft.atitle=Free+and+Open+Source+Software+versus+Internet+content+filtering+and+censorship%3A+A+case+study&rft.au=Shirazi%2C+Farid.&rft.aulast=Shirazi&rft.aufirst=Farid&rft.date=2012-04-01&rft.volume=85&rft.issue=4&rft.spage=920&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Systems+and+Software&rft.issn=01641212&rft_id=info:doi/","Open source software; Studies; Censorship; Open source; Software packages; Open Source Software; ICT; Internet; P2P; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Computers--Software; Free and open-source software; Systems design; 9178:Middle East; Filtering software; Iran; Communication discourse; Filtering","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects evolve and transform over time; therefore success must be examined longitudinally over a period of time. In this research, we examine two measures of project success: project popularity and developer activity, of 283 OSS projects over a span of 3 years, in order to observe changes over time. A comprehensive research model of OSS success is developed which includes both extrinsic and intrinsic attributes. Results show that while many of the hypothesized relationships are supported, there were marked differences in some of the relationships at different points in time lending support to the notion that different factors need to be emphasized as the OSS project unfolds over time.

One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

So it was important to reassess the factors enabling OSS adoption in order to enhance OSS utilization within public sector organisations. This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-08 17:20:55","2025-04-08 17:37:10","","","","2","17","","","","","","","","","","English","","","ABI/INFORM Global","2546081220","","","Place: Wollongong Publisher: Australasian Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/na1qJ?_a=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%3D%3D&_s=N0WDCOWv2H3E1ddURTiZTg8qVwo%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Australasian+Journal+of+Information+Systems&rft.atitle=Enablers+of+Open+Source+Software+adoption%3A+A+case+study+of+APS+organisations&rft.au=Gurusamy%2C+Kavitha%3BCampbell%2C+John.&rft.aulast=Gurusamy&rft.aufirst=Kavitha&rft.date=2012-01-01&rft.volume=17&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Australasian+Journal+of+Information+Systems&rft.issn=14498618&rft_id=info:doi/10.3127%2Fajis.v17i2.731","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Computers--Computer Systems; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

This phenomenon is also known as ""Inner Source"". While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Following an initial systematic literature review to generate seed category data constructs, the authors performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques.","2011-12","2025-04-08 17:20:56","2025-04-08 17:29:28","","1319","","12","53","","","","","","","","","","English","","","ABI/INFORM Global","894730546","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","; /Users/mgone/Zotero/storage/GBTD6URT/Stol et al. - 2011 - A comparative study of challenges in integrating O.pdf","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=A+comparative+study+of+challenges+in+integrating+Open+Source+Software+and+Inner+Source+Software&rft.au=Stol%2C+Klaas-Jan%3BBabar%2C+Muhammad+Ali%3BAvgeriou%2C+Paris%3BFitzgerald%2C+Brian.&rft.aulast=Stol&rft.aufirst=Klaas-Jan&rft.date=2011-12-01&rft.volume=53&rft.issue=12&rft.spage=1319&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Empirical studies; Open source; Software engineering; Software; Open-source software; Open Source Software; Software development; Challenges; Case study; 5240:Software & systems; Public domain; Systems development; Computers--Data Base Management; 9130:Experimental/theoretical; Systems integration; Comparative studies; Inner source; System integration; Inner Source","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For these companies, choosing the correct license determines business success. When the available open source stack and licensing options grow, so does the need to understand the interplay among licensing, sourcing decisions, and business goals. A model of license choice emphasizes different licenses and rationalizes the choice of an open source software (OSS) license. This is crucial for smaller companies and start-ups that don't have the tools and knowledge to perform a thorough investigation of all the consequences of their license choice every time they employ OSS.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ''joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

In the project execution process, control aligns individual behaviors toward the organizational goals via the Internet and becomes critical to the success of OSS projects. This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community. The study contributes to a better understanding of OSS project organizations and processes, and provides advice for OSS development.","2011","2025-04-08 17:20:56","2025-04-08 18:34:12","","26-42","","1","22","","","","","","","","","","English","","","ABI/INFORM Global","2954642973","","","Place: Hershey Publisher: IGI Global","","; ; /Users/mgone/Zotero/storage/CWBP9XLY/Lin et al. - 2011 - A Study of Open Source Software Development from C.pdf","https://media.proquest.com/media/hms/PFT/1/FF6YX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=6d%2Bi6am9M1LDqVW0E%2Fp1TGT7Yvg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=A+Study+of+Open+Source+Software+Development+from+Control+Perspective&rft.au=Lin%2C+Zhangxi%3BXu%2C+Bo%3BXu%2C+Yan.&rft.aulast=Lin&rft.aufirst=Zhangxi&rft.date=2011-01-01&rft.volume=22&rft.issue=1&rft.spage=26&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2011010102","Open source software; Open source; Software Development; Software; Open-source software; Software development; Control; Open Source Software (OSS); Software industry; Computers--Data Base Management; Industrial development; Open; OSS Development; Outcome; Project Management; Self-control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recently, the focus has shifted toward an examination of a newer construct -temporal dispersion (TD). The study of TD so far has been constrained mostly to conceptual work. This study furthers the understanding of TD through an empirical investigation of its relationship with open source software (OSS) team performance. In this paper, hypotheses are developed based on coordination theory, and analyses are performed using data collected from multiple archival sources comprising 100 OSS development teams. Results indicate that TD positively affects development speed and quality and that software complexity moderates the relation between TD and software quality.

Drawing on impression-management literature, especially first-impression management, the authors explore the potential role that the initial presentation of new OSS projects plays in attracting developers. The article presents preliminary findings from a pilot study including interviews and an exploratory quantitative analysis for further research.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-08 17:20:57","2025-04-08 18:14:01","","656","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","196420145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Using+the+DEMO+methodology+for+modeling+open+source+software+development+processes&rft.au=Huysmans%2C+Philip%3BVen%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Huysmans&rft.aufirst=Philip&rft.date=2010-06-01&rft.volume=52&rft.issue=6&rft.spage=656&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Computers--Data Base Management; Ontology; Demo; Process modeling; DEMO; Enterprise ontology; Software process modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our analysis draws on a large sample of projects registered at Sourceforge.net, the world's largest incubator of open source software activity. We test the hypothesis that skill variety of participants is associated with project performance. We also explore whether the level of modularization of project activities is correlated with performance. Our econometric estimations show that skill heterogeneity is associated with project survival and performance. However, the relationship between skill diversity and performance is non-monotonic. Design modularity is also positively associated with the performance of the project. Finally, the interaction between skill heterogeneity and modularity is negatively associated with performance.

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

A large data set retrieved from a project repository is used to test these hypotheses. The main results are that if Norden-Rayleigh-based approaches are used, they need to be complemented in order to account for the addition of new features during a product life cycle, and that programmer-participation based effort models result in distinctly lower estimations of effort than those based on output metrics, such as lines of code.

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-08 17:20:58","2025-04-08 17:20:58","","449-462","","5","16","","","","","","","","","","English","","","ABI/INFORM Global","212365312","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/b6OaT?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yiXUHeA3Bd5m9qlApbZJ63Be1aM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Management+%26+Computer+Security&rft.atitle=Evaluating+the+performance+of+open+source+software+projects+using+data+envelopment+analysis&rft.au=Wray%2C+Barry%3BMathieu%2C+Richard.&rft.aulast=Wray&rft.aufirst=Barry&rft.date=2008-10-20&rft.volume=16&rft.issue=5&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Information+Management+%26+Computer+Security&rft.issn=09685227&rft_id=info:doi/10.1108%2F09685220810920530","Open source software; Studies; Productivity; Business And Economics--Management; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

In this article we investigate the structure and the coordination practices adopted by development teams during the bug-fixing process, which is considered one of main areas of FLOSS project success. In particular, based on a codification of the messages recorded in the bug tracking system of four projects, we identify the accomplished tasks, the adopted coordination mechanisms, and the role undertaken by both the FLOSS development team and the FLOSS community. We conclude with suggestions for further research.","2008","2025-04-08 17:20:58","2025-04-08 17:34:11","","1-30","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954644395","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/KG6YX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=UXaG9bW1%2BZYM5VLhEFi9BtuwzX0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Bug+Fixing+Practices+within+Free%2FLibre+Open+Source+Software+Development+Teams&rft.au=Crowston%2C+Kevin%3BScozzi%2C+Barbar.&rft.aulast=Crowston&rft.aufirst=Kevin&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040101","Open source software; Open source; software development; Software; Open-source software; Coordination; Teams; Software development; Distributed computing; Computers--Data Base Management; Tracking systems; Bulletin boards; Codification; Fixing; free/libre open source software; bug-fixing processes; coordination practices","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-08 17:20:59","2025-04-08 17:53:52","","142-156","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","211770348","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aQ4UT?_a=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&_s=skz%2By9xiJklpExxCBn8Dys3vIXk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Innovation+Management&rft.atitle=Online+innovation%3A+the+case+of+open+source+software+development&rft.au=Vujovic%2C+Sladjana%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=Vujovic&rft.aufirst=Sladjana&rft.date=2008-01-01&rft.volume=11&rft.issue=1&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Innovation+Management&rft.issn=14601060&rft_id=info:doi/10.1108%2F14601060810845268","Open source software; Innovation; Communication; Information technology; Studies; Business And Economics--Management; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Communication technologies; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Open systems; Public domain; Technological change; Innovations; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Following a case study methodology, we examined developer interaction data from three active and successful FLOSS projects using qualitative research methods, specifically inductive content analysis, to identify the task-assignment mechanisms used by the participants. We found that 'self-assignment' was the most common mechanism across three FLOSS projects. This mechanism is consistent with expectations for distributed and largely volunteer teams. We conclude by discussing whether these emergent practices can be usefully transferred to mainstream practice and indicating directions for future research.

Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

Secondly, these licenses are mainly enforced by pro-socially motivated contributors. We characterize the conditions under which OSS communities develop and sustain pro-social commitments. We point out the vulnerability of these conditions to developments in patent legislation.

This paper develops and tests a model of the impacts of license restrictiveness and organizational sponsorship on two indicators of success: user interest in, and development activity on, open source software development projects. Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.

Service discovery is an essential mechanism to achieve this goal. Driven primarily by the OSS requirements, this paper proposes a new service discovery methodology for next generation OSS -- model-based service discovery (MBSD). MBSD takes advantage of the OMG MDA (model-driven architecture) technology. The system architecture of MBSD and its operation and implementation are presented. The proposed methodology is briefly validated through an OSS scenario.

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-08 17:21:00","2025-04-08 17:21:00","","","","2","48","","","","","","","","","","English","","","ABI/INFORM Global","237056523","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Open+source+software+for+medical+image+processing+and+visualization&rft.au=Yoo%2C+Terry+S%3BAckerman%2C+Michael+J.&rft.aulast=Yoo&rft.aufirst=Terry&rft.date=2005-02-01&rft.volume=48&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/10.1145%2F1042091.1042120","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Research & development--R&D; United States--US; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Computers--Data Communications And Data Transmission Systems; Digital image processing; Image; Medical imaging","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This observation, however, has not been discussed in much detail and critically addressed by the software engineering community. Most of the claims associated with open source appear to be weakly motivated and articulated. For this reason, this paper proposes some qualitative reflections and observations on the nature of open source software and on the most popular and important claims associated with the open source approach. The ultimate goal of the paper is to identify the concepts and intuitions that are really peculiar to open source, and to distinguish them from features and aspects that can be equally applied to or found in proprietary software.

This research investigates the evolution of open source software using a case study of the Samba project. Through the application of both qualitative and quantitative techniques, Samba's software development and evolution over a seven-year period are tracked and assessed. This assessment and the findings of similar, previously reported studies lead us to propose a general framework for the evolution and the key drivers of open source software evolution.

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-08 17:21:00","2025-04-08 17:21:00","","94-112","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","821692253","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/8v97U?_a=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&_s=pUsDcFs3MVZkPLVZxMuyqK90UPQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Open+source+software+and+software+patents%3A+A+constitutional+perspective&rft.au=Pfaffenberger%2C+Bryan.&rft.aulast=Pfaffenberger&rft.aufirst=Bryan&rft.date=1999-10-01&rft.volume=12&rft.issue=3&rft.spage=94&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-999-1029-x","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Usability is a clear concept that encompassing both task and user characteristics as well as functionality. Usability is an essential factor that affects user acceptance and OSS sustainability, which is considered as the key to the success of the OSS. To some extent, usability is one concern of the larger issue of system acceptability and sustainability. Therefore, usability is an important factor that needs to be considered since the software that is not usable is not going to be sustainable. The objective of this paper is to review researchers' efforts to improve, investigate, and evaluate the usability factor that may affect the OSS acceptability and sustainability and map the research scenery from the articles into a comprehensible structured taxonomy, which would help the researchers to identify different research gaps of this field. A survey of the usability in OSS conducted and 6033 studies identified by a search in four scholarly databases using a query that includes the keywords (usability or learnability or efficiency or satisfaction) and (open source software or OSS). A total of 46 studies are selected. By manually searching in ACM, Springer, and Google Scholar five other studies identified, and thus a total of 51 studies were the final set that includes in this paper. Based on research topics, a taxonomy created and divided into four principal categories which improve OSS usability, analyze OSS usability, evaluate OSS usability, and select and adopt OSS. A comprehensive overview and synthesis of these categories are presented as well. This paper contributes to identifying the possible opportunities and gaps for enabling the participation of interested researchers in this research area. And give possibilities for extending the use of usability research and practices to create more sustainable software. Also, helps in selecting suitable OSS among the alternatives.","2019","2025-04-08 17:21:57","2025-04-08 17:21:57","","65913-65933","","","7","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","open source software; sustainability; Usability; satisfaction; efficiency; learnability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Information, communication and information technology have made developing business becomes very competitive. It is very crucial for companies to have fast and accurate access to mission-critical business information in order to maintain its competitiveness. The ability to establish network connections between the existing systems becomes a must in order to optimize the use of critical information. To realize this, the implementation of system integration looks promising. However, system integration process is not an easy task because it involves variety of systems with different organizations backgrounds. The main objective of this paper is to propose an integration model that is generic and easily adapted by many organizations. The Information Management Division, Public Sector Department in Malaysia is chosen as a case study. The systems used in this department will be analyzed and problems faced will be identified. Research methodology conducted includes the Analysis Phase, Design Phase, Development Phase and Testing Phase. In order to support the proposed model, prototype called myIntegration is implemented based on OpenSyncro. OpenSyncro is an open source software (OSS) meant for Enterprise Application Integration (EAI). The Testing Phase was carried out by taking into account the actual test scenario involving the Department A (owner of the Malaysian Personal Record) and Department B (Human Resources Manager of Malaysian Civil Servants). Tests conducted have shown that the exchange of information between the Department A and B have been successfully realized. The finding from this research, where a new integration model has been created, can be referred by any government or private organizations in developing their systems integration facilities. The model also besides reducing the requirement of hardware; also reduces the dependency to proprietary products. In addition, the prototype developed, which based on OpenSyncro is capable in providing an alternative solution to the IT community to anchor any systems integration project at a lower cost and in a user friendly environment.","2011","2025-04-08 17:21:57","2025-04-08 17:21:57","","13-18","","","","","","","","","","","ACAD CONFERENCES LTD","CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND","English","","","","","","","Type: Proceedings Paper","","","","open source software; Enterprise Application Integration (EAI); integration model; middleware solution; system integration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However empirical studies on modularity of OSS systems have resulted in confusing results. To account for underlying mechanisms of those confusing results, we systematically examine widely studied OSS projects. Based on our systematic review on technical and organizational structures, we suggest that organizational circumstances of OSS production are at least in a continuum of tightly-coupled and loosely- coupled organizational circumstances of production in which both geographically distributed volunteers and paid developers with organizational ties work together (albeit separately over time). Furthermore, organizational circumstances of OSS production appear to be dynamic, as firms move in and out of OSS production communities over time. In essence we argue that the reason for the confusing empirical results was a persistent assumption that organizational circumstances of OSS production are static or unitary; rather what matters is the organizational circumstances of production in any episode of contribution. This research agenda paper proposes future inquiries to develop a comprehensive picture of ecological shift in different levels of system modularity and organizational circumstances of OSS production over time and through episodes.","2014","2025-04-08 17:21:57","2025-04-08 17:21:57","","","","","","","","","","","","","ASSOC INFORMATION SYSTEMS","P.O.

Since then, European universities have been involved in the development of the so-called European Higher Education Area (EHEA), including the adoption of a system of easily readable and comparable degrees, the European co-operation in quality assurance, and the promotion of mobility and European dimension in higher education. In this framework, the use of Free Open Source Software (FOSS) could provide several advantages, related to both the freedom given to users and the strengths of its peer-to-peer development model. In fact, some of the most outstanding characteristics of the FOSS (free, democratic, sustainable and technologically competitive educational model, cooperative and competitive relationships,.) result to be coincident with the main aims of the European Higher Education Area. In this paper we describe the role that this Free Open Source Software could play in the University context, also providing some statistical evidence about FOSS penetration and its recent evolution. Furthermore, since the implementation of the new university degrees can be considered as a “break point”, we briefly describe our FOSS experiences at the University of Oviedo, involving Statistics and Econometrics. Finally, we summarize the conclusions and describe the main challenges that FOSS must face during the coming years.","2012","2025-04-08 17:21:57","2025-04-08 17:21:57","","4841-4846","","","","","","","EDULEARN Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1117 Type: Proceedings Paper","","","","FOSS; Econometrics; Bologna Process; EHEA; Gretl; University","","Chova, LG; Torres, IC; Martinez, AL","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume - suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017-06","2025-04-08 17:21:57","2025-04-08 17:36:18","","43-66","","2","29","","","","","","","","","","English","","","","","","","Place: 701 E CHOCOLATE AVE, STE 200, HERSHEY, PA 17033-1240 USA Publisher: IGI GLOBAL Type: Article","","; ","https://media.proquest.com/media/hms/PFT/1/wC7YX?_a=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&_s=AH2MYk0kmnJKLtLEtVIDIizdS%2Bw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+and+End+User+Computing&rft.atitle=Developers%2C+Quality+Control+and+Download+Volume+in+Open+Source+Software+%28OSS%29+Projects&rft.au=Hill%2C+Geoffrey%3BDatta%2C+Pratim%3BCandice+Vander+Weerdt.&rft.aulast=Hill&rft.aufirst=Geoffrey&rft.date=2017-04-01&rft.volume=29&rft.issue=2&rft.spage=43&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+and+End+User+Computing&rft.issn=15462234&rft_id=info:doi/10.4018%2FJOEUC.2017040103","Open source software; Open source; Software; Open-source software; Open Source Software; Quality control; Segmented Regression; Software development; Computers--Electronic Data Processing; Developer Limit; Downloading; Quality Control; Quality Control Index; Regression Discontinuity; Tragedy of the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""
-"2Q9M5RA4","journalArticle","2024","Moon, Eunyoung; Howison, James","A dynamic perspective on software modularity in open source software (OSS) development: A configurational approach","INFORMATION AND ORGANIZATION","","1471-7727","10.1016/j.infoandorg.2023.100499","","To reduce technical and task interdependencies, modularization has been considered important in OSS development. However, the existing literature implicitly takes a static view that software structure and organizational structure are established early on and change slowly over time, if at all. Such a view does not fully reflect the complex and dynamic nature of software development and tends to overlook the role played by human agents as they ramp involvement up and down over time. This study considers that coordination practice plays an important role in altering technical interdependencies in OSS development. This study investigates coordination practices that result in changes in software coupling-in particular, increases in software coupling. This study automatically analyzes the code in 72 software releases and 1033 task episodes of three successful OSS projects-GNU grep, IPython, and Scikit-image. This study takes a fine-grained practice-oriented perspective that views the way that the work is done as constituting the organization. In our conceptualization, OSS contributors use a configuration of multiple organizational elements, enacted and varying across specific episodes of practice. In line with this perspective, this study takes a configurational approach, uses fuzzy-set qualitative comparative analysis (fsQCA) to analyze episodes that led to decreases, no changes, and increases in software coupling during the inter-release periods in which the level of software coupling increased significantly, which we call focal period. We find that co-work involving multiple individuals tends to result in code that adds technical dependencies (increases in software coupling) during the focal period.

Influenced by the “creative elements” of OSS, individuals in organizations often forget that the end result of software implementation is to improve productivity, thereby creating a negative impression on OSS implementation strategy as a whole. In this study, we argue that fit between the individual's task, values and work demands can influence or hinder the sustained use of OSS. We explore how task-technology fit and two dimensions of person-organization fit (value-based fit and demand-ability fit) interact with each other to influence productivity performance. Using survey data, we find that congruence between the organization's OSS values and the individual user's OSS values (value-based fit), decreases productivity performance, whereas, fit between an individual's OSS skills and the organizational task demands (demandability fit), increases productivity performance.

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project's time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project's progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.","2015-06","2025-04-08 17:21:58","2025-04-08 17:33:34","","1-23","","2","7","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","; ","https://media.proquest.com/media/hms/PFT/1/VW9VI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=loezPgn1rKCLMKeitMCXhMNka4U%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Pacific+Asia+Journal+of+the+Association+for+Information+Systems&rft.atitle=Application+of+Survival+Model+to+Understand+Open+Source+Software+Release&rft.au=Sen%2C+Ravi%3BNelson%2C+Matthew%3BChandrasekar+Subramaniam.&rft.aulast=Sen&rft.aufirst=Ravi&rft.date=2015-07-01&rft.volume=7&rft.issue=2&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Pacific+Asia+Journal+of+the+Association+for+Information+Systems&rft.issn=19437536&rft_id=info:doi/10.17705%2F1pais.07201","Open source software; Open source; FLOSS; OSS; Software; Survival analysis; Open-source software; Open source project; Success; Computers--Computer Systems; survival; Public domain; OSS popularity; hazard; ordinal regression; OSS success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We are based on previous literature about creating institutions to governing the commons. One of the key goals is institutional reporting to members of the community, so we believe that a reporting model based on social responsibility framework is clearly suitable for this purpose. Social responsibility and sustainability are about enabling organizations to incorporate creation of social, environmental and economic value into core strategy and operations; their reporting is key to create value for organizations, their stakeholders and society as a whole. To reach our goal, we asked a panel of open source experts their opinion about the key success factors and other relevant variables for the purpose of recommending a methodology to calculate specific indicators to be disclosed on social responsibility reports.","2015","2025-04-08 17:21:58","2025-04-08 17:21:58","","369-397","","1","9","","","","","","","","","","English","","","","","","","Place: Unit 3N, 6 Osborn Street, LONDON, E1 6TD, ENGLAND Publisher: UBIQUITY PRESS LTD Type: Article","","","","peer production; open source software; sustainability; social responsibility; Free software; reporting","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

Survivability, critical for maintaining project quality and trustworthiness, is closely linked to issue activity, as unresolved issues reflect a decline in maintenance capacity and problem-solving ability. Thus, analyzing issue retention rates provides valuable insights into a project's health. This study evaluates OSS survivability by identifying the features that influence issue activity and analyzing their relationships with survivability. Kaplan-Meier survival analysis is employed to quantify issue activity and visualize trends in unresolved issue rates, providing a measure of project maintenance dynamics. A random forest model is used to examine the relationships between project features-such as popularity metrics, community engagement, code complexity, and project age-and issue retention rates. The results show that stars significantly reduce issue retention rates, with rates dropping from 0.62 to 0.52 as stars increase to 4000, while larger codebases, higher cyclomatic complexity, and older project age are associated with unresolved issue rates, rising by up to 15%. Forks also have a nonlinear impact, initially stabilizing retention rates but increasing unresolved issues as contributions became unmanageable. By identifying these critical factors and quantifying their impacts, this research offers actionable insights for OSS project managers to enhance project survivability and address key maintenance challenges, ensuring sustainable long-term success.","2025-01","2025-04-08 17:21:59","2025-04-08 17:21:59","","","","2","15","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open source software; software maintenance; survivability; Kaplan-Meier survival function; random forest","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

System changes are often done without considering their effects on the system structure. These changes often introduce structural anomalies between the concrete (as-built) and the conceptual (as-designed) architecture which can impede program understanding. The problem of architectural drift is especially pronounced in open source systems, where many developers work in isolation on distinct features with little co-ordination. In this paper we present our experiences with repairing the architectures of two large open source systems (the Linux operating system kernel and the VIM text editor) to aid program understanding. For both systems, we were successful in removing many structural anomalies from their architectures.","2000","2025-04-08 17:21:59","2025-04-08 17:21:59","","48-59","","","","","","","INTERNATIONAL WORKSHOP ON PROGRAM COMPREHENSION","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc, Tech Comm Software Engn ISSN: 1092-8138 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""
-"BHYYBLEH","journalArticle","2001","McGowan, D","Legal implications of open-source software","UNIVERSITY OF ILLINOIS LAW REVIEW","","0276-9948","","","The proliferation of computer technology and the advent of the Internet have created many new relationships and problems that raise questions about traditional legal and economic principles. The development of “open-source” or “free” software is an example of this phenomenon. Unlike the traditional producers of computer software - Microsoft for example - open-source software is often developed by computer programmers from all over the world, each submitting contributions to the code, and distributed without charge or for a minimal fee. Open-source software is generally passed from programmer to programmer, with the understanding that improvements may be made, but that the improvements must be distributed freely, without any attempt to “privatize” the program. The existence of such relationships among programmers raise several interesting questions. First, how do large-scale open-source projects come into being? One open-source project, the GNU/Linux operating system, even threatens the market share of Microsoft's operating systems - a feat that calls traditional economic theories on the operation of the firm into question. A more important question is whether the open-source model is sustainable and generalizable. Ultimately, one wonders what role the law will play in the open-source community - a community that seems to operate in the absence of traditional legal principles. In this article, which was introduced at the University of Illinois College of Law Symposium on Intellectual Property Challenges in the Next Century, Professor McGowan addresses these questions. Using the GNU/Linux operating system as a case study, he probes the organization of the open-source community and the philosophies of its leading members in order to understand how traditional firm models, intellectual property, and contract law might apply. Professor McCowan concludes by reviewing recent attempts by courts to impose traditional principles in computer software transaction disputes. Ultimately, it appears that the open-source community cannot be neatly categorized.

However, if OSS have few contributors and are lacking in maintenance activities, such as bug fixes, are used, it can lead to significant costs and resource allocation due to maintenance discontinuation. Since OSS are developed by a diverse group of contributors, the consistency of their involvement may vary, making continuous support and maintenance unpredictable. Therefore, it is necessary to identify the status of each OSS to avoid increased maintenance costs when selecting OSS for use. To address these issues, we use polynomial regression to predict trends in bug-fixing activities and evaluate the survivability of OSS accordingly. We predict the trend of bug-fixing activities in OSS, using factors such as popularity, number of contributors, and code complexity. A lower trend value indicates more vigorous activity. In this paper, we conduct data collection and extraction, generating model, and model testing and evaluation to predict survivability using these data. After collecting data through various tools, the models of different degrees are generated using K-fold cross-validation. The model with the highest performance is selected based on the RMSE (Root Mean Squared Error) and RSE (Residual Standard Error). Then, the chosen model is employed to predict the survivability of OSS and compare it with actual outcomes. This method is experimented with on OSS used in the KakaoTalk commercial messenger app. As a result, several OSS are predicted to have low survivability, and among them, five are analyzed. It is observed that, in reality, activities such as delayed or discontinued release updates occurred. These findings can support OSS users in selecting OSS for cost-saving purposes and alert OSS administrators to the need for solutions to ensure project survival.","2024-04","2025-04-08 17:21:59","2025-04-08 17:21:59","","","","7","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","GitHub; open source software; software maintainability; polynomial regression; survivability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.","2009","2025-04-08 17:21:59","2025-04-08 17:36:11","","532-549","","3-4","109","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","; /Users/mgone/Zotero/storage/92FUTPR3/Casalo et al. - 2009 - Determinants of success in open source software ne.pdf; ","https://media.proquest.com/media/hms/OBJ/zudiT?_a=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&_s=8lhX7MA2qul1DMgk4JEc8k5yJeA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Industrial+Management+%26+Data+Systems&rft.atitle=Determinants+of+success+in+open+source+software+networks&rft.au=Casal%C3%B3%2C+Luis+V%3BCisneros%2C+Jes%C3%BAs%3BFlavi%C3%A1n%2C+Carlos%3BGuinal%C3%ADu%2C+Miguel.&rft.aulast=Casal%C3%B3&rft.aufirst=Luis&rft.date=2009-05-01&rft.volume=109&rft.issue=4&rft.spage=532&rft.isbn=&rft.btitle=&rft.title=Industrial+Management+%26+Data+Systems&rft.issn=02635577&rft_id=info:doi/10.1108%2F02635570910948650","Open source software; Studies; Collaboration; Open source; Participation; Hypotheses; Software; Open-source software; Consumer behavior; Success; Satisfaction; Brand loyalty; Internet; Social networks; Open systems; Loyalty; Users; Public domain; Reputations; 9130:Experimental/theoretical; Business And Economics--Computer Applications; 7100:Market research; 5250:Telecommunications systems & Internet communications; Consumer behaviour; Reputation; Corporate image; Social networking service; User studies","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since there is no central mechanism that governs the process of team formation, it is interesting to investigate if there are any significant correlations between project quality and the characteristics of the team members. However, for such analysis to be possible, we need good metrics of a project quality. This paper develops two such metrics, first one reflecting project's popularity, and the second one - the quality of support offered by team members to users. The first metric is based on the number of `stars' a project is given by other GitHub members, the second is obtained using survival analysis techniques applied to issues reported on the project by its users. After developing the metrics we have gathered characteristics of several GitHub projects and analyzed their influence on the project quality using statistical regression techniques.","2014","2025-04-08 17:21:59","2025-04-08 17:21:59","","80-94","","","8851","","","","Lecture Notes in Computer Science","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: Microsoft Res; Facebook; Yahoo Labs; Stanford, Ctr Computat Soc Sci; Barcelona Media; SocialSensor; IEEE Special Tech Community Social Networking ISSN: 0302-9743 Type: Proceedings Paper","","","","OSS; online collaboration; survival analysis; performance metrics","","Aiello, LM; McFarland, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we present the CrOSSD project, which aims to build a database of OSS projects and measure their current project “health” status. In the project, we will use both quantitative and qualitative metrics to evaluate the health of OSS projects. The quantitative metrics will be gathered through automated crawling of meta information such as the number of contributors, commits and lines of code. Qualitative metrics will be gathered for selected “critical” projects through manual analysis and automated tools, including aspects such as sustainability, funding, community engagement and adherence to security policies. The results of the analysis will be presented on a user-friendly web platform, which will allow users to view the health of individual OSS projects as well as the overall health of the OSS ecosystem. With this approach, the CrOSSD project provides a comprehensive and up-to-date view of the health of OSS projects, making it easier for developers, maintainers and other stakeholders to understand the health of OSS projects and make informed decisions about their use and maintenance.","2023","2025-04-08 17:21:59","2025-04-08 17:59:44","","156-159","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Amazon Science; Baidu; Megagon Labs; Zhipu AI; Google; Booking Com; eBay; Bloomberg Engn; Netflix; ACM SIGWEB; Univ Texas Austin, Sch Informat; Data World; Inst Fdn Machine Learning Type: Proceedings Paper","","","","software security; open-source software; open-source health; quality monitoring","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.","2013-08","2025-04-08 17:22:00","2025-04-08 17:52:53","","619-643","","4","44","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","/Users/mgone/Zotero/storage/KMV97M3K/Peng et al. - 2013 - Learning and Open Source Software License Choice.pdf; ","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Decision+Sciences&rft.atitle=Learning+and+Open+Source+Software+License+Choice&rft.au=Peng%2C+Gang%3BMu%2C+Jifeng%3BDi+Benedetto%2C+C+Anthony.&rft.aulast=Peng&rft.aufirst=Gang&rft.date=2013-08-01&rft.volume=44&rft.issue=4&rft.spage=619&rft.isbn=&rft.btitle=&rft.title=Decision+Sciences&rft.issn=00117315&rft_id=info:doi/","Open source software; Leadership; Studies; Business And Economics--Management; Open source; Software license; Open-source software; Open Source Software; License; Social Networks; Decision-making; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Proprietary; Decision analysis; Licensing; Organizational learning; Experiential learning; Experiential Learning; License Choice; Vicarious Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of “going open source” and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

Substantial research was done to investigate central projects such as Linux kernel but we have only a limited understanding of how the periphery of the larger OSS ecosystem is interconnected through technical dependencies, code sharing, and knowledge flows. We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-08 17:22:00","2025-04-08 17:22:00","","3","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Assoc Comp Machinery Special Interest Grp Software Engn Type: Proceedings Paper","","","","Software Ecosystems; Empirical Software Engineering; Software Measurement","","Dumas, M; Pfahl, D; Apel, S; Russo, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While open source software has similarly distributed decision making and involves code and information flows similar to those in ordinary supply chains, the actual networks necessary to quantify and communicate risks in software supply chains have not been constructed on large scale. This work proposes to close this gap by measuring dependency, code reuse, and knowledge flow networks in open source software. We have done preliminary work by developing suitable tools and methods that rely on public version control data to measure and comparing these networks for R language and emberjs packages. We propose ways to calculate the three networks for the entirety of public software, evaluate their accuracy, and to provide public infrastructure to build risk assessment and mitigation tools for various individual and organizational participants in open sources software. We hope that this infrastructure will contribute to more predictable experience with OSS and lead to its even wider adoption.","2018","2025-04-08 17:22:00","2025-04-08 17:22:00","","458-459","","","","","","","Proceedings of the IEEE-ACM International Conference on Software Engineering Companion","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; Microsoft Res ISSN: 2574-1926 Type: Proceedings Paper","","","","open source; software supply chain; knowledge flow; risk management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sample of open source projects includes all mature projects driven by the Eclipse Foundation as of February 2008. Three types of project diversity were used: i) organizational - measured by number of committers per organization per project, ii) contribution - measured by the number of commits made per organization per project, and iii) technical - measured by the number of commits made per given software file type. Success was measured by means of i) economic metrics, including the number of corporate adoptions and the number of jobs postings including the project name, and ii) development metrics, including the project popularity and the growth of the intensity of members' activity. The paper makes two main contributions. First, we contribute to the literature on open source software and diversity. Second, we introduce economic success metrics to the empirical assessment of open source software project success.","2009","2025-04-08 17:22:00","2025-04-08 17:22:00","","155-168","","","26","","","","Lecture Notes in Business Information Processing","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: Talent First Net; Univ Ottawa, Telfer Sch Business; Carleton Univ; Univ Quebec; HEC Montreal; Univ Neuchatel ISSN: 1865-1348 Type: Proceedings Paper","","/Users/mgone/Zotero/storage/N3XPCKB3/Enayat et al. - 2009 - Impact of Diversity on Open Source Software.pdf","","","","Babin, G; Kropf, P; Weiss, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Comparing to traditional software engineering approach, we found this approach is absolutely reversed. Open source development and delivery occurs on Internet time. Developers are not confined to a geographic area. They work voluntarily on a project of their choice; they are not forced to join a particular project just because it needs more developers or the project has a high degree of urgency. Developers work for peer-recognition and self-satisfaction. In the open source community, each and every project has an equal priority. Software designed under open source is not released until the project owner thinks that the software has reached a functional stage. One of the success stories is the Linux operating system. Open Source software is always in an evolutionary stage: it never reaches a final stage. As new requirements emerge the software is enhanced by the user/developers. In this paper, we give an introduction to the insights of open source software development. We then elucidate the perceived benefits and point out the differences between open source and closed source software development approaches. At the end we propose a new model for open source software development.","2003","2025-04-08 17:22:00","2025-04-08 17:22:00","","136-143","","","","","","","","","","","INT INST INFORMATICS & SYSTEMICS","14269 LORD BARCLAY DR, ORLANDO, FL 32837 USA","English","","","","","","","Backup Publisher: Int Inst Informat & System Type: Proceedings Paper","","","","","","Callaos, N; Lesso, W; Schewe, KD; Atlam, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects. (C) 2013 Elsevier B.V.

Accordingly, various articles in the literature assess the quality and success of OSS, by using different quality attributes and metrics and different approaches. Though this variety can be considered as a positive indicator of research interest and maturation on one side, it creates a kind of jungle in defining and understanding the terms `quality' and `success' on the other side. Based on this challenge, in this study, we targeted a systematic mapping (SM) of the articles on quality and success of OSS. More than 474 articles have appeared in this area between the years 2002 and 2017, and the final pool of 128 articles is obtained by defining and applying inclusion and exclusion criteria. SM was employed to develop a classification scheme and categorized the existing body of articles with respect to five research questions (RQs) on: contribution and research types, quality criteria and metrics, success criteria and metrics, the relation of quality and success, and demographics. We observed that the majority of the articles assess the concept of quality as `code quality', whereas the concept of success is mostly perceived as `market success' and/or `developer activity'. Moreover, the metrics of `contributing developers/users', and the quality attribute of `functionality' are the quality criteria most employed in the assessment of success.","2019","2025-04-08 17:22:01","2025-04-08 17:22:01","","363-370","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","open source; OSS; software metrics; success; software; quality; systematic mapping","","Staron, M; Capilla, R; Skavhaug, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (Von Hippel and Von Krogh, 2003, 2006), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that - (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described. (C) 2013 Elsevier B.V.

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lockin, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-04-08 17:22:01","2025-04-08 17:22:01","","7-12","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives-voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study I investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.

The traditional market failure argument suggests that innovation is characterized by high investment and low copy cost, and firms have difficulty in internalizing the fruits of their innovative effort. Thus, technology firms are seeking more patents, expanding their scope and overhauling their business models around intellectual property. Yet paradoxically, with the progress and development of information technology, open source software (OSS) plays an important role in expanding enterprise informatization. For example, Linux is developed quickly by this open way. Some firms have found the ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is one example. In this article, the author introduces a model of OSS based on its network effects to understand how the enterprises decide their activities in this open market competition. This article describes the inherent reasons of open source movement from the view of the oligopoly structure. At the same time, this article analyses the effect of leader enterprise and follower enterprise on market structure and the different activities of these enterprises after the source has been opened. Finally, we make suggestions that companies at the leading edge are often in such a strong position that they do need the support of down-streams companies to broaden their technologies successfully and to decrease their risks in order to leverage the value of the technological portfolio. On the other hand, this article suggests that follower enterprises have incentive to take part in the development of open-source software only when the market has grown up.","2008","2025-04-08 17:22:02","2025-04-08 17:22:02","","669+","","","254","","","","International Federation for Information Processing","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","ISSN: 1571-5736 Type: Proceedings Paper","","","","open source software; enterprise normalization; OSS model","","Xu, LD; Tjoa, AM; Chaudhry, SS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs. closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.","2015","2025-04-08 17:22:02","2025-04-08 17:22:02","","215-228","","","37","","","","Routledge Studies in Innovation Organization and Technology","","","","ROUTLEDGE","29 W 35TH ST, NEW YORK, NY 10001 USA","English","","","","","","","Type: Article; Book Chapter","","","","gradual concept of openness; tangible open source products; vale capture","","Herstatt, C; Ehls, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Studying the evolution of software and understanding it is a vocal topic of study in software engineering. One of the primary concepts of software evolution is that the internal quality of a software system declines when it evolves. In this paper, the method of evolution of the internal quality of object-oriented open-source software systems has been examined by applying a software metric approach. More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics. The results and observations of this research include: (i) there is a significant difference between different systems concerning the LOC variable (ii) there is a significant correlation between all pairwise comparisons of internal quality metrics, and (iii) the effect of complexity and inheritance on the LOC was positive and significant, while the effect of Coupling and Cohesion was not significant.","2021-06","2025-04-08 17:22:02","2025-04-08 17:22:02","","","","12","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","software evolution; software engineering; software metrics; internal quality; open-source software systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Over time, organizations face the OSS adoption challenge strengthening mainly its internal and technical elements. However, the rapid changes on business dynamics, and the comprehensiveness and fast development of open paradigms, show us that a new set of conditions must be satisfied to reach a successfully OSS adoption. These conditions, considered as a critical success factors, involve a wide range of resources, capacities and skills, both in internal and external scopes. Hence, although adopter organizations should be better prepared to face the challenges related to collaborative innovation, they do not have a systematic approach to value its readiness level to face the adoption challenges. In this context, the present research work proposes a model to assess the organizational readiness, considering the adopter as part of a live business ecosystem, where the relationships originated on co-development with developers' communities, have mutual business impact at strategic, tactic, and operative level.","2021","2025-04-08 17:22:02","2025-04-08 17:22:02","","800-807","","","","","","","","","","","SCITEPRESS","AV D MANUELL, 27A 2 ESQ, SETUBAL, 2910-595, PORTUGAL","English","","","","","","","Backup Publisher: INSTICC Type: Proceedings Paper","","","","Open Source Software Adoption; Open Innovation; Organizational Readiness Assessment","","Filipe, J; Smialek, M; Brodsky, A; Hammoudi, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article we argue that disadvantage is more due to gendered behavior than to categorical discrimination: women are at a disadvantage because of what they do, rather than because of who they are. Using data on entire careers of users from GitHub.com, we develop a measure to capture the gendered pattern of behavior: We use a random forest prediction of being female (as opposed to being male) by behavioral choices in the level of activity, specialization in programming languages, and choice of partners. We test differences in success and survival along both categorical gender and the gendered pattern of behavior. We find that 84.5% of women's disadvantage (compared to men) in success and 34.8% of their disadvantage in survival are due to the female pattern of their behavior. Men are also disadvantaged along their interquartile range of the female pattern of their behavior, and users who don't reveal their gender suffer an even more drastic disadvantage in survival probability. Moreover, we do not see evidence for any reduction of these inequalities in time. Our findings are robust to noise in gender recognition, and to taking into account particular programming languages, or decision tree classes of gendered behavior. Our results suggest that fighting categorical gender discrimination will have a limited impact on gender inequalities in open source software development, and that gender hiding is not a viable strategy for women.","2019-07-06","2025-04-08 17:22:02","2025-04-08 17:22:02","","","","","8","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Open source; Software development; Gender inequality; Gendered behavior","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, newcomers face many barriers when making their first contribution, leading in many cases to dropouts. Due to the collaborative nature of community-based OSS projects, newcomers may be susceptible to social barriers, such as communication breakdowns and reception issues. In this article, we report a two-phase study aimed at better understanding social barriers faced by newcomers. In the first phase, we qualitatively analyzed the literature and data collected from practitioners to identify barriers that hinder newcomers' first contribution. We designed a model composed of 58 barriers, including 13 social barriers. In the second phase, based on the barriers model, we developed FLOSScoach, a portal to support newcomers making their first contribution. We evaluated the portal in a diary-based study and found that the portal guided the newcomers and reduced the need for communication. Our results provide insights for communities that want to support newcomers and lay a foundation for building better onboarding tools. The contributions of this paper include identifying and gathering empirical evidence of social barriers faced by newcomers; understanding how social barriers can be reduced or avoided by using a portal that organizes proper information for newcomers (FLOSScoach); presenting guidelines for communities and newcomers on how to reduce or avoid social barriers; and identifying new streams of research.","2019-04","2025-04-08 17:22:02","2025-04-08 17:22:02","","247-290","","1-2","28","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Joining; Newcomers; Onboarding; Open source software; Online communities; FLOSS; Socialization; Challenges; Difficulties; Beginners; Entry; New contributor; Newbies; Qualitative study; Social barriers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most of the educational organizations have already adopted smart learning environment by upgrading their infrastructure and with proper capacity building among staff members. But in the education sector, sustainability of technology is always being a challenge. To develop learning materials, many institutions have already started using free and open source software (FOSS) tools. FOSS gives freedom to the developer with the provision of various customization options as per the requirements of the class or subject. Moreover, in the longer run, free and open source software could be considered as the best option in education for e-learning implementation, for sustainability. There are many tools which are available for e-learning resource development. Some of them are available online and some are available as an installer for the various platform. In order to adapt ICT in education, especially in non-IT specialization, the faculty members need the training to learn and implement these tools in their classes. But there are many tools, which are specially designed for educators with basic knowledge of computers. Educators can plan their sessions, based on content, duration as well as the level of the subject and the students. This research paper will highlight various aspects of the implementation of FOSS, in education by using such easy-to-implement tools and techniques. This would provide general guidelines for the development of various e-learning solutions for technology-enhanced teaching and learning practices in higher education.","2017","2025-04-08 17:22:02","2025-04-08 17:57:37","","1075-1079","","","","","","","","","","","INT ORGANIZATION CENTER ACAD RESEARCH","YUNUS EMRE CAD AKASYA SK NO 22, UGUR MUMCU, ISTANBUL, KARTAL 00000, TURKEY","English","","","","","","","Backup Publisher: Int Org Ctr Acad Res Type: Proceedings Paper","","","","technology; innovation; Open Source Software; Linux; Free and open source software; E-learning; Enhanced teaching and learning practices; Interactive educational tools; Multimedia in education; Sustainability in education; Technology-enhanced learning; education technology; information systems","","Uslu, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To more effectively manage and progress the projects, it is important and beneficial to rank the programmers and thus, predict the developer candidates. In this work, we propose to combine machine learning techniques with existing complex network node ranking algorithms to improve the prediction results. Specifically, we have made the following contributions: (1), we have designed a novel machine learning-based classifier with significantly improved prediction performance; (2), we have constructed and tested various networks built based on the programmer email communication information; and (3), we have used real-world project data to compare different techniques and validate our methods. Experimental results demonstrate that our technique reduces the error rate by 25% compared with the second best. Moreover, we discover that the KK nearest neighbor (KNN)-based machine learning algorithm and non-directional temporal network with a time window of 1-3 months give the best prediction results.","2018-06","2025-04-08 17:22:02","2025-04-08 17:22:02","","845-868","","6","28","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","machine learning; Open source software; complex network; ranking algorithm","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In 2005, several university libraries, university college libraries and other research libraries met and discussed a joint effort to create institutional archives. The meeting resulted in the Pepia project with BIBSYS as a software partner. The project group decided to use the open source system DSpace as a software platform. A standard DSpace installation runs on a Tomcat servlet container. BIBSYS does not use this container, and we therefore needed to configure DSpace to get it to run successfully on our server. In addition we had some problems with integrating the DSpace development structure with our integrated development environment. Further we needed to create a new build process that effectively could build more than 30 applications from one source code. These changes were quite time consuming, but they were necessary so that we could have an efficient work environment. Out of the box DSpace has many of the functionalities that an institutional archive requires. In spite of this we needed to alter some of the functionality, especially the user management system. DSpace is a complex system, but with the active community we could get the help we needed. BIBSYS Brage, the result of the Pepia project, was launched as a beta version in December 2006. We look forward to develop BIBSYS Brage further, and are confidant that it will become a great system for the consortium.","2007-12","2025-04-08 17:22:03","2025-04-08 17:22:03","","","","19","","","","","","","","","","","English","","","","","","","Place: C ADOLF FLORENSA S-N, BARCELONA, 08028, SPAIN Publisher: UNIV BARCELONA, SERVEI PUBLICACIONS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To detect such vulnerabilities, finding OSS reuses in COTS software has become imperative. While scalable to tens of thousands of OSS projects, existing binary-to-source matching approaches are severely imprecise in analyzing COTS software products, since they support only a limited number of code features, compute matching scores only approximately in measuring OSS reuses, and neglect the code structures in OSS projects. We introduce a novel binary-to-source matching approach, called B2SFINDER1, to address these limitations. First of all, B2SFINDER can reason about seven kinds of code features that are traceable in both binary and source code. In order to compute matching scores precisely, B2SFINDER employs a weighted feature matching algorithm that combines three matching methods (for dealing with different code features) with two importance-weighting methods (for computing the weight of an instance of a code feature in a given COTS software application based on its specificity and occurrence frequency). Finally, B2SFINDER identifies different types of code reuses based on matching scores and code structures of OSS projects. We have implemented B2SFINDER using an optimized data structure. We have evaluated B2SFINDER using 21991 binaries from 1000 popular COTS software products and 2189 candidate OSS projects. Our experimental results show that B2SFINDER is not only precise but also scalable. Compared with the state of the art, B2SFINDER has successfully found up to 2.15x as many reuse cases in 53.85 seconds per binary file on average. We also discuss how B2SFINDER can be leveraged in detecting OSS reuse vulnerabilities in practice.","2019","2025-04-08 17:22:03","2025-04-08 17:22:03","","1038-1049","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Comp Soc Tech Council Software Engn; ACM Special Interest Grp Artificial Intelligence; ACM Special Interest Grp Software Engn Type: Proceedings Paper","","","","OSS; Code Reuse; Binary-to-Source Matching; Code Feature; COTS Software; One-Day Vulnerability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This process is reviewed and illustrated with OsiriX, a fast DICOM viewer program for the Apple Macintosh. Materials and methods OsiriX is an oss for the Apple Macintosh under Mac OS X v10.4 or higher specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: multiplanar reconstruction, surface rendering, volume rendering and maximum Intensity projection. All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT). OsiriX was developed using the Apple Xcode development environment and Cocoa framework as both a DICOM PACS workstation for medical imaging and an image processing software package for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging. Results OsiriX is an open source program by Antoine Rosset, a radiologist and software developer, was designed specifically for the needs of advanced imaging modalities. The software program turns an Apple Macintosh into a DICOM PACS workstation for medical imaging and image processing. OsiriX is distributed free of charge under the GNU General Public License and its source code is available to anyone. This system illustrates how open software development for medical imaging tools can be successfully designed, implemented and disseminated. Conclusion oss development can provide useful cost effective tools tailored to specific needs and clinical tasks. The integrity and quality assurance of open software developed by a community of users does not follow the traditional conformance and certification required for commercial medical software programs. However, open software can lead to innovative solutions designed by users better suited for specific tasks.","2006-12","2025-04-08 17:22:03","2025-04-08 17:22:03","","187-196","","4","1","","","","","","","","","","English","","","","","","","Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Maintenance effort is usually measured in person-hours used to perform a maintenance task. However, maintenance effort data are usually only available for strictly managed software, such as closed-source software. In other software projects that do not have complete maintenance records, especially some open-source software, there are no direct data for maintenance effort, which precludes the establishment of a maintenance effort model. In this paper, we report a series of studies aimed at presenting a method for indirectly predicting the maintenance effort of open-source software. This report covers two parts of our research. First, we examine the maintenance data from NASA SEL closed-source software projects and identify some software measures that can be used to indirectly represent maintenance effort. Second, based on the findings in the first part, we analyze 121 recent versions of Linux, and use linear regression to construct two indirect maintenance effort models for the Linux project. Our study demonstrates the applicability of this approach to indirectly predicting the maintenance effort and improving the software maintenance process.

These challenges of understanding and evolving existing code can be illustrated in academic settings by leveraging the rich and varied volume of Open Source Software (OSS) code. To teach SE with OSS, however, it is necessary to select uniform projects of appropriate size and complexity. This paper reports on our search for suitable OSS projects to teach an introductory SE course with a focus on maintenance and evolution. The search turned out to be quite labor intensive and cumbersome, contrary to our expectations that it would be quick and simple. The chosen projects successfully demonstrated the maintenance challenges, highlighting the promise of using OSS. The burden of selecting projects, however, may impede widespread integration of OSS into SE and other computing courses.","2014","2025-04-08 17:22:03","2025-04-08 17:22:03","","397-402","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM Special Interest Grp Comp Sci Educ Type: Proceedings Paper","","","","Open Source; Maintenance; Software Engineering; Program Comprehension","","Dougherty, J; Nagel, K; Decker, A; Eiselt, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most of the research studies have focused on identifying individual personal motives for participating in the development of an OSS project, analyzing specific solutions, or the OSS movement, itself. No studies have been found which have undertaken research on the impact of user experience and training on OSS. The study reported here sought to identify factors that predict acceptance of technologies based on OSS after training in these solutions. A research model based on the Technology Acceptance Model (Davis, 1989) was developed. Furthermore, the possible moderating effects of users' gender, age and level of education were analyzed. It was found that external determinants such as user training, user fit, technological complexity and trainers' support were important indicators in the success of adopting these solutions.

Open Source Software (OSS) has becoming widely adopted by commercial, public and academic organisations. Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world! OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization's success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems. The main aim of this paper is to measure the evolution of OSS using, Eclipse Metrics (EM), with Guice software (GS) as a case study. In addition, this paper gives a brief literature review on OSS and how it has evolved.","2009","2025-04-08 17:22:03","2025-04-08 17:58:20","","211-218","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","/Users/mgone/Zotero/storage/9PJA2Y8W/Al-Ajlan - 2009 - The Evolution of Open Source Software using Eclips.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the discrete modeling framework has been proposed to study the reliability growth process of OSS systems with multiple releases. The proposed model is based upon the assumption that during up-gradation some new faults are introduced in the code in addition to the left over fault content of the previous version. To validate our model, we have chosen two successful open source projects-Mozilla and Apache for its multi release failure datasets. Graphs representing goodness of fit of the proposed model have been drawn. The parameter estimates and measures of goodness of fit criteria suggest that the proposed software reliability growth model for multi-release OSS fits the actual datasets very well. An optimal release policy has been formulated by taking into account the cost of fault removal during testing and operational phases and reliability targets pre-specified by the decision makers. In addition, numerical example along with the sensitivity analysis has been provided to illustrate optimal release policy.","2018-04","2025-04-08 17:22:04","2025-04-08 17:22:04","","","","2","15","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","Open source software; discrete software reliability growth model; fault removal process; multi-release software system; release time","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Yet, newcomers face a steep learning curve during OSS onboarding in which they must overcome a multitude of technical, social, and knowledge barriers. To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., “good first issues”), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.","2023","2025-04-08 17:22:04","2025-04-08 17:54:36","","324-336","","","","","","","International Conference on Software Engineering-Software Engineering Education and Training","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISSN: 2832-756X Type: Proceedings Paper","","","","open source software; open source onboarding; software engineering education","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In spite of having these benefits, numerous challenges can be faced during the multi-release OSS development. Some of the challenges can be the generation of errors during the addition of new features. To address the changing fault detection process, a change point phenomenon is considered so as to give more practicality to the model.

The culture and norms of FLOSS appear to be formulated by what is privileged/marginalized by men in the context of FLOSS, and such men's valuing is likely to threaten women FLOSS participants' face. Our findings are 1) in the FLOSS context, there are gender-based differences in determining what threatens face on the basis of gendered expectations of what is polite, and 2) women-dominated FLOSS participants are “practically” polite in software development practices.

However, the impacts of microblogging follower network on OSS project success are rarely studied. In this study, we adopt a social network perspective to identify and hypothesize that three microblogging network mechanisms will positively affect OSS project success through knowledge sharing, and attracting more skillful and eminent developers. Using longitudinal data from a large online OSS community called Ohloh, we empirically examine the impacts of various factors for these two type of mechanisms on the commercial and technological successes of OSS projects. We found that preferential attachment and structure hole factors are supported, while accumulative advantage factors are partially supported. Our findings may provide insights for OSS stakeholders to effectively manage microblogging techniques for achieving project success.","2013","2025-04-08 17:22:04","2025-04-08 17:22:04","","3178-3186","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc; Univ Hawaii, Shidler Coll Business ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because students are accustomed to gathering information using commercial search engines, they can overlook high-quality library resources. To connect with student researchers when they need library resources, many libraries have built online research guides tied to specific subjects and courses. These guides can address specific assignments where research is required, and course instructors can point students to the guides to assist them in completing their research assignments successfully. In 2006, Oregon State University (OSU) Libraries developed an open source software product called Library a la Carte that librarians can use to construct research guides easily and quickly. The code was made available to other libraries, and a number of institutions have adopted the tool. A successful user community has grown up around Library a la Carte, but development up to this point has been the sole responsibility of OSU Libraries. We are now embarking on building a robust developer community, to contribute code, to build additional features and to take Library a la Carte into the future. As part of our plan to move forward, we are testing a hosted (cloud-based) version of the software. This paper introduces Library a la Carte, presents what was learned from the test and discusses moving forward with building a developer community. In addition, we touch on the benefits and challenges of building and sustaining an open source product from the ground up.","2012","2025-04-08 17:22:05","2025-04-08 17:22:05","","6471-6476","","","","","","","INTED Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION A& DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1079 Type: Proceedings Paper","","","","open source software; cloud computing; libraries; library guides","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We compare successful and unsuccessful projects on volume of communication and on use of inclusive pronouns as an indication of efforts to create intimacy among team members. An innovation of the paper is that use of inclusive pronouns is measured using natural language processing techniques. We also compare the volume and content of communication produced by core (committer) and peripheral members and by those peripheral members who are later elected to be core members.

This paper investigates the contribution of Free/Libre Open-Source Software (FLOSS) towards fair, and conflict-free practices through promoting collaboration, transparency, and resource accessibility. Our study investigates how the adoption of decentralized online social networks (DOSN) like Mastodon (microblogging) and PeerTube (video sharing), which operate on the ActivityPub protocol, contributes to sustainable practices within the electronics sector by fostering a federated universe (Fediverse). It is demonstrated how FLOSS, in the form of Alternative Mobile Operating Systems (AMOS) including Android open-source custom ROMs or mobile Linux systems, gain traction due to enhanced privacy protection, improved usability through tracker-free software and alternative app stores, and adherence to EU directives on the right to self-repair. As AMOS mature for everyday use, they attract consumers, thereby contributing towards sustainable electronics development. Furthermore, the Fediverse's Application Programming Interfaces (APIs) enable seamless information exchange between instances, allowing for nuanced moderation that safeguards user privacy. This approach contrasts with centralized commercial networks, where algorithm-driven operations often prioritize profit over user well-being.","2024","2025-04-08 17:22:05","2025-04-08 17:22:05","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","","","FLOSS; sustainability; Fediverse; alternative mobile operating systems (AMOS); decentralized","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we describe an empirical study to investigate the mechanisms and behaviours that developers use to find code changes they are competent to review. We also explore how stakeholders interact with one another during the review process. We manually examine hundreds of reviews across five high profile OSS projects.

The overall success of peer code review, commonly used in open source projects, has likely contributed strongly to this success. Code review is an emotionally loaded practice, with public exposure of reputation and ample opportunities for conflict. We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process. It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market. In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-04-08 17:22:05","2025-04-08 18:14:36","","1073-1083","","","","","","","International Conference on Software Engineering","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE Comp Soc, Tech Comm Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","open source; Motivation; motivation; Open Source; code review; Code Review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study shows that open source software has certain facets; code, community, coordination mechanisms, license and documentation. Each facet is not stable; indeed, it is changing and mutable. This creates possibilities, potential but also recalcitrance, and barriers. The interesting point of departure of our study is how open source software a much touted transparent and open phenomenon is by its nuanced and layered mutability able to make the process and practices surrounding it less visible.

The open source community-led software DSpace has had great success encouraging the creation of national user groups; in the UK, North America, and Germany, the Groups have been active for many years. However, it was in 2018, thanks to a renewed focus on international engagement and more diverse representation of the global community in governance groups, that the national communities entered into a new phase: 15 new national User Groups have been formed all over the world since then, while the German user group evolved into the “DSpace-Konsortium Deutschland”, founded by 25 institutions, marking a pivotal point for membership options and National User Group participation within DSpace Governance.

In GitHub, developers are allowed to fork repositories and copy repositories without asking for permission, which make contribution to projects much easier than it has ever been. It is significant to predict the number of forks for open source software projects. The prediction can help GitHub to recommend popular projects, and guide developers to find projects which are likely to succeed and worthy of their contribution. In this paper, we use stepwise regression and design a model to predict the number of forks for open source software projects. Then we collect datasets of 1,000 repositories through GitHub's APIs. We use datasets of 700 repositories to compute the weight of attributes and realize the model. Then we use other 300 repositories to verify the prediction accuracy of our model. Advantages of our model include: (1) Some attributes used in our model are new. This is because GitHub is different from traditional open source software platforms and has some new features. These new features are used to build our model. (2) Our model uses project information within t month after its creation, and predicts the number of forks in the month T (t < T). It allows users to set the combination of time parameters and satisfy their own needs. (3) Our model predicts the exact number of forks, rather than the range of the number of forks (4) Experiments show that our model has high prediction accuracy. For example, we use project information with 3 months to prediction the number of forks in month 6 after its creation. The correlation coefficient is as high as 0.992, and the median number of absolute difference between prediction value and actual value is only 1.8. It shows that the predicted number of forks is very close to the actual number of forks. Our model also has high prediction accuracy when we set other time parameters.","2014","2025-04-08 17:22:06","2025-04-08 17:22:06","","40-47","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Type: Proceedings Paper","","/Users/mgone/Zotero/storage/Q3ZNYSB6/Chen et al. - 2014 - Predicting the Number of Forks for Open Source Sof.pdf","","Open Source Software; Fork","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The health of ecosystems is an important prerequisite for a long term sustainable OSS (Open Source Software) tool-chain in the MDD area, which can aid strategic decision making for potential adoption within a company context. We have established details on the extent to which developers and users are active in two specific OSS ecosystems, and identified organisational influence for both ecosystems. We find that the investigated tools are promising regarding the health of their ecosystems, and a natural next step for the company would be to proceed with a pilot study in order to analyse the effectiveness of the investigated tools in company contexts.","2011","2025-04-08 17:22:06","2025-04-08 17:22:06","","348+","","","365","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: CAPES, Minist Educ, Coordinat Improvement Higher Educ Personnel; CNPQ, Minist Sci & Tecnol, Natl Council Sci & Technol Dev; FAPESB, State Bahia Res Agcy; Petrobras ISSN: 1868-4238 Type: Proceedings Paper","","","","","","Hissam, SA; Russo, B; Neto, MGD; Kon, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making `good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.","2009","2025-04-08 17:22:06","2025-04-08 18:54:09","","51-71","","1","74","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Ethnos&rft.atitle=Freedom+Imagined%3A+Morality+and+Aesthetics+in+Open+Source+Software+Design&rft.au=Leach%2C+James%3BNafus%2C+Dawn%3BKrieger%2C+Bernhard.&rft.aulast=Leach&rft.aufirst=James&rft.date=2009-03-01&rft.volume=74&rft.issue=1&rft.spage=51&rft.isbn=&rft.btitle=&rft.title=Ethnos&rft.issn=00141844&rft_id=info:doi/10.1080%2F00141840902751188","ethics; Ethics; Software; Technology; Imagination; freedom; article; Property; Computer Software; sociology of technology; 1772:sociology of science; Ideologies; Morality; Social Dynamics; progress; social form","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some countries have successfully created extensive information technology infrastructures, yet software use continues to be reliant on pirated sources. The experiences of licensing regulation violations and increasing virus attacks indicate that part of the problem is a consequence of dependencies created by the use of proprietary software within resourcescarce economies. Recent growth in the use of free and open-source software (FOSS) by various public-and private-sector agencies suggests an alternative path to software self-suffciency for a resource-scarce country like Cuba. There is, however, an interesting background to current software use within Cuba that makes it unique among several less-developed countries. Apart from the well-known advantages, FOSS use could be essential to shape the future scenario of Cuba. The present paper first delineates some of the Cuban background, basically characterized by lack of freedom in technology ownership and access to external information. The potential of FOSS use within existing conditions in Cuba is then analyzed. Finally, conclusions are provided on the basis of a survey carried out in Cuba, arguing that there needs to be stronger political will to reduce gaps between goals and implementation reality to achieve intrinsic advantages of FOSS use successfully.","2006","2025-04-08 17:22:06","2025-04-08 17:22:06","","1-17","","1","3","","","","","","","","","","English","","","","","","","Place: UNIV SOUTHERN CALIFORNIA, KERCKHOFF HALL, 734 W ADAMS BLVD, MC7725, LOS ANGELES, CA 90089 USA Publisher: USC ANNENBERG PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Having tried both ways allows us to retrospectively; compare the effectiveness of “from scratch” implementation versus software evolution. By using the code bases of GNU GCC and Linux for the adaptation approach we gained valuable experiences with the comprehension and adaptation of large but sparsely documented code bases. In most cases, the adaptation of existing software proved to be by-far more effective than implementing from scratch. Surprisingly, the effort needed to comprehend the existing voluminous source codes repeatedly proved to be less than expected. In this paper we discuss our positive and negative experiences and the various factors influencing success and failure.

Against conventional wisdom this approach has been wildly successful in the general software market-probably because the openness lets programmers the world over obtain, critique, use, and build upon the source code without licensing fees. Linux, a UNIX-like operating system, is the best known success. But computer scientists at the University of California, Berkeley began the tradition of software sharing in the mid 1970s with BSD UNIX and distributed the major internet network protocols as source code without a fee. Medical informatics has its own history of Open Source distribution: Massachusetts General's COSTAR and the Veterans Administration's VISTA software have been distributed as source code at no cost for decades. Bioinformatics, our sister field, has embraced the Open Source movement and developed rich libraries of open-source software. Open Source has now gained a tiny foothold in health care (OSCAR GEHR, OpenEMed). Medical informatics researchers and funding agencies should support and nurture this movement. In a world where open-source modules were integrated into operational health care systems, informatics researchers would have real world niches into which they could engraft and test their software inventions. This could produce a burst of innovation that would help solve the many problems of the health care system. We at the Regenstrief Institute are doing our part by moving all of our development to the open-source model. (C) 2002 Elsevier Science Ireland Ltd.

To this end, we contribute a process for decomposing trust in a complex large-scale system into key trust relationships, systematically identifying behavior-based indicators for the components of trust for a given relationship, and in turn operationalizing data-driven metrics for those indicators, allowing for the wide-scale measurement of trust in practice.","2024","2025-04-08 17:22:07","2025-04-08 17:22:07","","57-61","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc Type: Proceedings Paper","","/Users/mgone/Zotero/storage/EIEBXIU2/Boughton et al. - 2024 - Decomposing and Measuring Trust in Open-Source Sof.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This software metrics is formulated by analyzing modularity traits such as size, complexity, cohesion, and coupling of 59 Java-based OSS Projects from sourceforge. net using SONAR tool. These OSS Projects are selected since they have been downloaded more than 100K times and believed to have the required modularity trait to be successful. The software metrics related to modularity in class, package and system level of these projects are extracted and analyzed. The similarities found are then analyzed to determine the class quality, package quality, and then combined with system architecture measure to formulate the Modularity Index.

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer. Finally, we develop a committer-identification model to assist OSS projects identifying future committers.","2014","2025-04-08 17:22:07","2025-04-08 17:22:07","","47-56","","","","","","","International Conference on Quality Software","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Reliabil Soc; UT Dallas; IEEE Comp Soc ISSN: 1550-6002 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the energy sector has not yet embraced open-source software to the same level. We discuss how existing open-source software principles can be applied to the unique challenges of the energy sector during the transition towards higher penetration of renewable energy resources. To provide an overview of the current state of the open-source software landscape, we collected and analyzed 388 open-source projects, in terms of project activities, community composition, relevant licenses, and commonly used programming languages.

However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma, allowing for early diagnosis and intervention. We have developed Specvis, a free and open-source application written in Java programming language that can run on any personal computer to meet this requirement (http://www. specvis. pl/). Specvis was tested on glaucomatous, retinitis pigmentosa and stroke patients and the results were compared to results using the Medmont M700 Automated Static Perimeter. The application was also tested for inter-test intrapersonal variability. The results from both validation studies indicated low inter-test intrapersonal variability, and suitable reliability for a fast and simple assessment of visual field impairment. Specvis easily identifies visual field areas of zero sensitivity and allows for evaluation of its levels throughout the visual field. Thus, Specvis is a new, reliable application that can be successfully used for visual field examination and can fill the gap between confrontation and perimetry tests. The main advantages of Specvis over existing methods are its availability (free), affordability (runs on any personal computer), and reliability (comparable to high-cost solutions).","2017-10-13","2025-04-08 17:22:07","2025-04-08 17:22:07","","","","10","12","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We develop a research model and present hypotheses that should be tested in the future. To empirically assess this model, we intend to survey OSS project members through the largest development platform Sourceforge.

However, the problematic nature of OSS adoption is readily evidenced in the fairly frequent reports of problems, unforeseen hold-ups, and outright abandonment of OSS implementation over time. Beaumont Hospital, an Irish public sector organization, have embarked on the adoption of a range of OSS applications over several years, some of which have been successfully deployed and remain in live use within the organisation, whereas others, despite achieving high levels of assimilation over a number of years, have not been ultimately retained in live use in the organization. Using a longitudinal case study, we discuss in depth the deployment process for two OSS applications - the desktop application suite whose deployment was unsuccessful ultimately, and the email application which was successfully deployed. To our knowledge, this is the first such in-depth study into successful and unsuccessful OSS implementation. Given that our study was a longitudinal one in a single organization, we can control a number of potentially important influencing elements which would not be possible if multiple organizations were involved. In particular, the complex interaction of issues to do with voluntariness of adoption, image, trialability and absorptive capacity were critical influences in the process.","2007","2025-04-08 17:22:07","2025-04-08 17:54:02","","IS33","","","","","","","","","","","INSTICC-INST SYST TECHNOLOGIES INFORMATION CONTROL & COMMUNICATION","AVENIDA D MANUEL L, 27A 2 ESQUERDO, SETUBAL, 2910-595, PORTUGAL","English","","","","","","","Backup Publisher: INSTICC; Workflow Management Coalit; Interdisciplinary Inst Collaborat & Res Enterprise Syst & Technol Type: Proceedings Paper","","","","","","Filipe, J; Helfert, M; Shishkov, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Similarly, testability is a residual software property which the developers and users no longer ignore. This is because if the testability of software is high, the test effort and development cost decrease proportionally. This is the case because test effort is highly affected by testability. In this paper, we investigate the relationship between test effort and success of the open source software by employing source codes and easily accessible parameters from the repository. Moreover, the proposed methods are empirically examined by analyzing 17 open source software projects. According to the empirical results, a meaningful positive correlation is obtained between test effort and success.

There are many open-source architecture frameworks for UAS that claim the autonomous operation of UAS, but they still have two main open issues: (1) level of autonomy, being in most of the cases limited and (2) versatility, being most of them designed specifically for some applications or aerial platforms. As a response to these needs and issues, this paper presents Aerostack, a system architecture and open-source multi-purpose software framework for autonomous multi-UAS operation. To provide higher degrees of autonomy, Aerostack's system architecture integrates state of the art concepts of intelligent, cognitive and social robotics, based on five layers: reactive, executive, deliberative, reflective, and social. To be a highly versatile practical solution, Aerostack's open-source software framework includes the main components to execute the architecture for fully autonomous missions of swarms of UAS; a collection of ready-to-use and flight proven modular components that can be reused by the users and developers; and compatibility with five well known aerial platforms, as well as a high number of sensors.

Based on the detected community structures, the system analyzes and visualizes the community evolution history of a project with a set of semantic-rich events, and quantify the strength of community evolution with respect to different events with a series of indexes. Built-in support to quantitative analysis and machine learning tasks based on the quantitative evolutionary events are provided.

Several OSS systems have achieved significant market success but they are rather server-side applications, such as the Apache Web server, MySQL database server, or other components of IT infrastructure. On the other hand, penetration of OSS systems on the market of desktop applications is rather limited and it is virtually dominated by products of one software vendor, i.e., Microsoft. In this chapter, the benefits and barriers of OSS implementation in Poland are investigated. Based on the well-known technology organization environment model of IT technology adoption of a simple model was developed and evaluated empirically, based on the data from the survey of 178 enterprises and public institutions. Statistical analysis using partial least squares (PLS) was performed. Of the four factors considered to determine adoption decisions (benefits, costs, environment, and organization), it was found that only perceived benefits and environment are significant.","2009","2025-04-08 17:22:08","2025-04-08 17:22:08","","461+","","","","","","","","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","Type: Proceedings Paper","","","","Open source software; Software adoption; Statistical survey","","Papadopoulos, GA; Wojtkowski, G; Wojtkowski, W; Wrycza, S; Zupancic, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although this data source has weaknesses, this involvement in the research process has considerable pedagogical value in teaching students research methodology. Statement of the Problem Most common software packages used to manage participant pools tend to be expensive, to the extent that it prohibits access for small institutions and departments. Literature Review Highlighting the problem, we cite research related to using undergraduates as participants, pedagogical value of these experiences, and current trends in software distribution. We then provide evidence of successful implementation of open-source software (OSS) in educational settings, and conclude with OSS options capable of addressing the problem of access. Teaching Implications By providing students research experiences, both as a researcher and as a participant, we enhance their understanding of this process. Secondary to this, we can foster within them a skill set that is valuable to disciplines outside of academia. Conclusion The implementation of an OSS system to manage research participants provides a cost-effective means to expand the learning and research opportunities of available to students.","2022-05-29","2025-04-08 17:22:08","2025-04-08 17:22:08","","","","","","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article; Early Access","","","","methodology; experiential learning; participant pool; recruitment; surveys","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The objective: to explore the evolution of a long-lived open source project with the intention of learning how code evolution has progressed over time. This investigation provides a case study of Nethack, an enormously popular open source game that has been in development for more than a decade. The Goal Question Metric approach was employed to derive measurement goals for the evaluation of open source software (OSS) evolution in Nethack. According to Lehman's laws, the incremental growth size of successive releases tends to decline during the active life of an evolving program. Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased. These findings raise questions concerning the evolution of other OSS applications.","2006","2025-04-08 17:22:09","2025-04-08 17:22:09","","47+","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: NASA Software Engn Lab; NASA Goddard Space Flight Ctr, Informat Syst Div; IEEE Comp Soc, TCSE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The lack of established metrics makes it difficult to formulate such strategy. While many projects have been formed and created, only a few managed to remain active. With the majority of these projects failing, firms need a reliable set of criteria to assess what makes a project appealing not only to developers but also to visitors, users and commercial sponsors. In this paper, we develop a theoretical model to explore the contextual and causal factors of project attractiveness in inducing activities such as source code contribution, software maintenance, and usage. We test our model with data derived from more than 4000 projects spanning 4 years. Our main findings include that projects' set of conditions such as license restrictiveness and their available resources provide the context that directly influence the amount of work activities observed in the projects. It was also found that indirect and unintended contributions such as recommending software, despite of being non-technical, cannot be ignored for project activeness, diffusion and sustainability. Finally, our analysis provide evidence that higher attractiveness leads to more code-related activities with the downside of slowing down responsiveness to address projects' tasks, such as the implementation of new features and bug fixes. Our model underscores the significance of the reinforcing effects of attractiveness and work activities in open source projects, giving us the opportunity to discuss strategies to manage common traps such as the liability of newness. We conclude by discussing the applicability of the research model to other user-led initiatives. (C) 2012 Elsevier B.V.

This study considers if it is possible from an organizational perspective for small to medium-sized cities to provide services and conduct business using only open source software (OSS). We examine characteristics of municipal government that may influence the adoption of OSS for the delivery of services and to conduct city business. Three characteristics are considered to develop an understanding of city behavior with respect to OSS: capability, discipline, and cultural affinity. Each of these general characteristics contributes to the successful adoption and deployment of OSS by cities. Our goal was to determine the organizational characteristics that promote the adoption of OSS. We conducted a survey to support this study resulting in 3316 responses representing 1286 cities in the Unites States and Canada. We found most cities do not have the requisite characteristics to successfully adopt OSS on a comprehensive scale and most cities not currently using OSS have not future plans for OSS.","2009","2025-04-08 17:22:09","2025-04-08 17:22:09","","1044+","","","","","","","Lecture Notes in Engineering and Computer Science","","","","INT ASSOC ENGINEERS-IAENG","UNIT 1, 1-F, 37-39 HUNG TO ROAD, KWUN TONG, HONG KONG, 00000, PEOPLES R CHINA","English","","","","","","","Backup Publisher: IAENG Soc Artificial Intelligence; IAENG Soc Bioinformat; IAENG Soc Comp Sci; IAENG Soc Data Min; IAENG Soc Elect Engn; IAENG Soc Imaging Engn; IAENG Soc Ind Engn; IAENG Soc Internet Comp & Web Serv; IAENG Soc Oper Res; IAENG Soc Sci Comp; IAENG Soc Software Engn; IAENG Soc Wireless Networks; IAENG Soc HIV/AIDS ISSN: 2078-0958 Type: Proceedings Paper","","","","Open Source Software; City Government; Municipal Government","","Ao, SI; Douglas, C; Grundfest, WS; Burgstone, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These have been used as the basis to support the discovery of successful genetic modifications of the microbial metabolism to address industrial goals. However, the use of these methods has been restricted to bioinformaticians or other expert researchers. The main aim of this work is, therefore, to provide a user-friendly computational tool for Metabolic Engineering applications. Results: OptFlux is an open-source and modular software aimed at being the reference computational application in the field. It is the first tool to incorporate strain optimization tasks, i.e., the identification of Metabolic Engineering targets, using Evolutionary Algorithms/Simulated Annealing metaheuristics or the previously proposed OptKnock algorithm. It also allows the use of stoichiometric metabolic models for (i) phenotype simulation of both wild-type and mutant organisms, using the methods of Flux Balance Analysis, Minimization of Metabolic Adjustment or Regulatory on/off Minimization of Metabolic flux changes, (ii) Metabolic Flux Analysis, computing the admissible flux space given a set of measured fluxes, and (iii) pathway analysis through the calculation of Elementary Flux Modes. OptFlux also contemplates several methods for model simplification and other pre-processing operations aimed at reducing the search space for optimization algorithms. The software supports importing/exporting to several flat file formats and it is compatible with the SBML standard. OptFlux has a visualization module that allows the analysis of the model structure that is compatible with the layout information of Cell Designer, allowing the superimposition of simulation results with the model graph. Conclusions: The OptFlux software is freely available, together with documentation and other resources, thus bridging the gap from research in strain optimization algorithms and the final users. It is a valuable platform for researchers in the field that have available a number of useful tools. Its open-source nature invites contributions by all those interested in making their methods available for the community. Given its plug-in based architecture it can be extended with new functionalities. Currently, several plug-ins are being developed, including network topology analysis tools and the integration with Boolean network based regulatory models.","2010-04-19","2025-04-08 17:22:09","2025-04-08 17:22:09","","","","","4","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper proposes a system security assessment method that integrates the risk relationships of open source software (OSS). Firstly, an OSS risk propagation relationship graph is constructed, and the Fuzzy Analytic Hierarchy Process (FAHP)-entropy weight method is adopted to allocate weights to the weakness assessment indicators of OSS, thereby improving the accuracy of quantifying OSS propagation risks. Then, on the attack graph, the analysis of threat values to host nodes and the probability of successful attack paths are optimized from three perspectives: vulnerabilities, OSSSC, and hosts. Experimental results demonstrate that this method, by combining open source risk factors and conducting multi-dimensional analysis, can more effectively assess the security threats faced by systems, providing a more accurate basis for security defense.","2024","2025-04-08 17:22:10","2025-04-08 17:22:10","","21-27","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: N Minzu Univ; Xidian Univ; Future Univ Hakodate; Chuzhou Univ; Ikueikan Univ Type: Proceedings Paper","","","","host status; OSSSC; system security; vulnerability assessment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Closed-loop experiments provide unique insights into brain dynamics and function. To facilitate a wide range of closed-loop experiments, we created an open-source software platform that enables high-performance real-time processing of streaming experimental data. Approach. We wrote Falcon, a C++ multi-threaded software in which the user can load and execute an arbitrary processing graph. Each node of a Falcon graph is mapped to a single thread and nodes communicate with each other through thread-safe buffers. The framework allows for easy implementation of new processing nodes and data types. Falcon was tested both on a 32-core and a 4-core workstation. Streaming data was read from either a commercial acquisition system (Neuralynx) or the open-source Open Ephys hardware, while closed-loop TTL pulses were generated with a USB module for digital output. We characterized the round-trip latency of our Falcon-based closed-loop system, as well as the specific latency contribution of the software architecture, by testing processing graphs with up to 32 parallel pipelines and eight serial stages. We finally deployed Falcon in a task of real-time detection of population bursts recorded live from the hippocampus of a freely moving rat. Main results. On Neuralynx hardware, round-trip latency was well below 1 ms and stable for at least 1 h, while on Open Ephys hardware latencies were below 15 ms. The latency contribution of the software was below 0.5 ms. Round-trip and software latencies were similar on both 32- and 4-core workstations. Falcon was used successfully to detect population bursts online with similar to 40 ms average latency. Significance. Falcon is a novel open-source software for closed-loop neuroscience. It has sub-millisecond intrinsic latency and gives the experimenter direct control of CPU resources. We envisage Falcon to be a useful tool to the neuroscientific community for implementing a wide variety of closed-loop experiments, including those requiring use of complex data structures and real-time execution of computationally intensive algorithms, such as population neural decoding/encoding from large cell assemblies.","2017-08","2025-04-08 17:22:10","2025-04-08 17:22:10","","","","4","14","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP PUBLISHING LTD Type: Article","","","","open-source software; closed-loop neuroscience; multi-threaded software; online burst detection; real-time processing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. Methods: This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Observations: Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Conclusion: Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future. The impact of these new technologies is particularly effective in image communication, PACS and teleradiology. (C) 2010 Elsevier Ireland Ltd.

The PCA denoising method is applied to ten scans of EBSPs from the same region of interest of a recrystallised nickel sample acquired with a decreasing S/N, achieved by reducing the exposure time while increasing the camera gain accordingly. That PCA denoising increases S/N in EBSPs is demonstrated by comparing indexing success rates after both Hough and dictionary indexing (HI and DI) of the Ni patterns having undergone one of four processing routes: i) standard static and dynamic background corrections (standard corrections), ii) standard corrections and pattern averaging with the four closest neighbours, iii) standard corrections and PCA denoising, and iv) standard corrections and pattern averaging followed by PCA denoising. Both pattern averaging and PCA denoising increases the indexing success rates for both indexing approaches for the studied Ni scans, with the former processing route providing the better success rates. The best success rates are obtained after pattern averaging followed by PCA denoising. The potential of PCA denoising to reveal additional pattern details compared to standard corrections and pattern averaging is demonstrated in a pattern from an orthoclase (KAlSi3O8) grain in a geological sample. Software code, and the Ni data sets, are released alongside this article as part of KIKUCHIPY, an open-source software package dedicated to processing and analysis of EBSPs.","2020","2025-04-08 17:22:10","2025-04-08 17:22:10","","","","","891","","","","IOP Conference Series-Materials Science and Engineering","","","","IOP PUBLISHING LTD","DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND","English","","","","","","","Backup Publisher: European Microbeam Anal Soc; Ametek GmbH, Edax Business Unit; Ametek, CAMECA Business Unit; Bruker Nano GmbH; European Commiss, JRC Directorate G Nucl Safety & Secur; Jeol; Micro Nano; Norwegian Univ Sci & Technol; Probe Software; NordicNano Solut AB; Target Messtechnik; TESCAN ORSAY HOLDING a s; Thermo Fisher Sci ISSN: 1757-8981 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While intra-operative ultrasound (iUS) guidance has shown clear potential to reduce surgery time, compared with clinical computed tomography (CT) guidance, rapid registration aiming to correct for patient misalignment has not been addressed. In this article, we present an open-source platform for pedicle screw navigation using iUS imaging. The alignment method is based on rigid registration of CT to iUS vertebral images and has been designed for fast and fully automatic patient re-alignment in the operating room. Two steps are involved: first, we use the iUS probe's trajectory to achieve an initial coarse registration; then, the registration transform is refined by simultaneously optimizing gradient orientation alignment and mean of iUS intensities passing through the CT-defined posterior surface of the vertebra. We evaluated our approach on a lumbosacral section of a porcine cadaver with seven vertebral levels. We achieved a median target registration error of 1.47 mm (100% success rate, defined by a target registration error <2 mm) when applying the probe's trajectory initial alignment. The approach exhibited high robustness to partial visibility of the vertebra with success rates of 89.86% and 88.57% when missing either the left or right part of the vertebra and robustness to initial misalignments with a success rate of 83.14% for random starts within +/- 20 degrees rotation and +/- 20 mm translation. Our graphics processing unit implementation achieves an efficient registration time under 8 s, which makes the approach suitable for clinical application.

We compare successful and unsuccessful projects on volume of communication by core (committer) and peripheral community members and on use of inclusive pronouns as an indication of efforts to create intimacy among team members. An innovation of the paper is that use of inclusive pronouns is measured using natural language processing techniques.

To lead an OSS project to a successful conclusion, researchers study how developers change source codes called patches in project repositories. In existing studies, we found an argument in the conventional patch acceptance detection procedure. It was so simplified that it omitted important cases from the analysis, and would lead researchers to wrong conclusions. In this research, we propose an algorithm to overcome the problem. To prove out our algorithm, we constructed a framework and conducted two case studies.

Open-source software allows members of the public to study, customize, and operate their own local copies of the software and source code, often without monetary fees. As such, releasing SAGES as open-source software assures prospective users that they retain complete control over the health data collected by SAGES-based systems, and aligns well with the model of self-sustainability intended for the operation of SAGES systems in resource-limited settings. Preparing two SAGES tools, OpenESSENCE and SAGES Mobile, for release as open-source software projects entailed a multifaceted, months-long effort that spanned policy, technical, and community considerations.

In such platforms, developers have to collaborate and deal with issues of collaboration in open-source software development. Although collaboration is challenging, collaborative development produces better software systems than any developer could produce alone. Several approaches have investigated collaboration challenges, for instance, by proposing or evaluating models and tools to support collaborative work. Despite the undeniable importance of the existing efforts in this direction, there are few works on collaboration from perspectives of developers. In this work, we aim to investigate the perceptions of open-source software developers on collaborations, such as motivations, techniques, and tools to support global, productive, and collaborative development. Following an ad hoc literature review, an exploratory interview study with 12 open-source software developers from GitHub, our novel approach for this problem also relies on an extensive survey with 121 developers to confirm or refute the interview results. We found different collaborative contributions, such as managing change requests. Besides, we observed that most collaborators prefer to collaborate with the core team instead of their peers. We also found that most collaboration happens in software development (60%) and maintenance (47%) tasks. Furthermore, despite personal preferences to work independently, developers still consider collaborating with others in specific task categories, for instance, software development. Finally, developers also expressed the importance of the social coding platforms, such as GitHub, to support maintainers, and contributors in making decisions and developing tasks of the projects. Therefore, these findings may help project leaders optimize the collaborations among developers and reduce entry barriers. Moreover, these findings may support the project collaborators in understanding the collaboration process and engaging others in the project.","2023-05","2025-04-08 17:22:10","2025-04-08 17:22:10","","","","5, SI","35","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","distributed collaboration; collaborative software development; collaboration in software development; open-source software projects; sustained developer community participation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although existing research recognizes the importance of trust, there is a lack of an effective and scalable computational method to measure trust in an OSS community. Consequently, OSS project members must rely on subjective inferences based on fragile and incomplete information for trust-related decision making. We propose an automated approach to assist a developer in identifying the trustworthiness of another developer. Our two-fold approach, first, computes direct trust between developer pairs who have interacted previously by analyzing their interactions via natural language processing. Second, we infer indirect trust between developers who have not interacted previously by constructing a community-wide developer network and propagating trust in the network. A large-scale evaluation of our approach on a GitHub dataset consisting of 24,315 developers shows that contributions from trusted developers are more likely to be accepted to a project compared to contributions from developers who are distrusted or lacking trust from project members. Further, we develop a pull request classifier that exploits trust metrics to effectively predict the likelihood of a pull request being accepted to a project, demonstrating the practical utility of our approach.","2019-12-30","2025-04-08 17:22:10","2025-04-08 17:22:10","","","","12","14","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We extract a series of measures based on those used in traditional inspection experiments. We measure the frequency of review, the size of the contribution under review, the level of participation during review, the experience and expertise of the individuals involved in the review, the review interval, and the number of issues discussed during review. We create statistical models of the review efficiency, review interval, and effectiveness, the issues discussed during review, to determine which measures have the largest impact on review efficacy. We find that OSS peer reviews are conducted asynchronously by empowered experts who focus on changes that are in their area of expertise. Reviewers provide timely, regular feedback on small changes.

An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweight open source systems for patient and sample information management. Results: We present a web-based tool for submission, management and retrieval of sample and research subject data. The system secures confidentiality by separating anonymized sample information from individuals' records. It is simple and generic, and can be customised for various biomedical studies.

However, since reused components are (by definition) generic, they need to be customized and integrated into a specific system before they can be useful. Since this integration is system-specific, the integration effort is non-negligible and increases maintenance costs, especially if more than one component needs to be integrated. This paper performs an empirical study of multi-component integration in the context of three successful open source distributions (Debian, Ubuntu and FreeBSD). Such distributions integrate thousands of open source components with an operating system kernel to deliver a coherent software product to millions of users worldwide. We empirically identified seven major integration activities performed by the maintainers of these distributions, documented how these activities are being performed by the maintainers, then evaluated and refined the identified activities with input from six maintainers of the three studied distributions. The documented activities provide a common vocabulary for component integration in open source distributions and outline a roadmap for future research on software integration.","2016-06","2025-04-08 17:22:11","2025-04-08 17:22:11","","960-1001","","3","21","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","/Users/mgone/Zotero/storage/W86QK8JJ/Adams et al. - 2016 - An empirical study of integration activities in di.pdf","","Debian; Software reuse; Open source distributions; Software integration; Ubuntu and FreeBSD","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores a prediction method based on fuzzy time series for predicting the future commit activity in open source software (OSS) projects. The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems. It is found that the predicted results of the computational method outperform various ARIMA models. Towards the end, a commit prediction model is used for each project to analyse the trends in their commit activity.","2016-10","2025-04-08 17:22:11","2025-04-08 17:22:11","","136-146","","5","10","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","public domain software; open source software projects; OSS projects; time series; ARIMA model; autoregressive integrated moving average models; autoregressive moving average processes; commit activity prediction; development community; fuzzy analysis; fuzzy set theory; fuzzy time series-based prediction method; software development management; software evolution prediction; time variant difference parameter","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.","2015-03","2025-04-08 17:22:11","2025-04-08 17:22:11","","224-237","","1","26","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software; intrinsic motivation; firm attributes; firm sponsorship; voluntary contributions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software is a recent and important example. Copyright restrictions on open-source projects stipulate that any user may modify the software so long as any resulting innovation is freely available to all. In economic parlance, the innovation is a public good. The economic theory of public-good provision raises a number of important questions. Who contributes to such a project, and who free rides? How might a social planner exploit the interdependence of project components to encourage contributions? Under what conditions will such actions result in successful provision? Using a simple game-theoretic framework and recent results from the study of equilibrium selection, we attempt to answer these questions. Under reasonable assumptions of asymmetry and less than complete information, the most efficient providers will contribute. Contributions can be elicited by `integrating' the provision process when providers are sufficiently optimistic about the success of the project. Otherwise, the social planner may be better off `separating' the components so that individual contributions are independent of each other. The analysis yields recommendations for the leaders of open-source projects and other similar collective-action problems.","2002","2025-04-08 17:22:11","2025-04-08 17:37:30","","446-461","","4","18","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Oxford+Review+of+Economic+Policy&rft.atitle=EQUILIBRIUM+SELECTION+AND+PUBLIC-GOOD+PROVISION%3A+THE+DEVELOPMENT+OF+OPEN-SOURCE+SOFTWARE&rft.au=Myatt%2C+David+P%3BWallace%2C+Chris.&rft.aulast=Myatt&rft.aufirst=David&rft.date=2002-12-01&rft.volume=18&rft.issue=4&rft.spage=446&rft.isbn=&rft.btitle=&rft.title=Oxford+Review+of+Economic+Policy&rft.issn=0266903X&rft_id=info:doi/","Open source software; Collective action; Business And Economics; Copyright; Linux; Success; Operating systems; Public domain; Innovations; Programmers; Public good; Externality; Wildlife conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there were few developers being paid directly for maintaining OSS projects in the past. The GitHub Sponsors program that brings financial supports to the general OSS developers in GitHub-the world's largest OSS platform may make a difference on this situation in the future. In this paper, we present a data set on GitHub Sponsors and conduct a data-driven study to analyze the participants of the program and the impact of sponsorships to developers' activities and their projects' outcomes and qualities. The results of our survey suggest that most developers state they will contribute more with sponsorships and provide some privilege for their sponsors. And through quantitative study, we find that developers make more contributions on GitHub after they got/offered sponsorships. Moreover, gaining sponsorship also has a weakly positive impact on developers' collaborators that did not get sponsorship. And not only developers, but their own or contributed projects also can be motivate by sponsorships. Our findings are useful to the community by understanding the impact of sponsorships on users' activities and projects' progress and sustainability, and helping the managers to improve the current financial support mechanism.","2022","2025-04-08 17:22:11","2025-04-08 17:22:11","","924-933","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc Type: Proceedings Paper","","","","Open Source Software; Data-Driven Study; Financial Support; GitHub Sponsors","","Leong, HV; Sarvestani, SS; Teranishi, Y; Cuzzocrea, A; Kashiwazaki, H; Towey, D; Yang, JJ; Shahriar, H","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Unfortunately, there is Pareto principle in OSSD projects, and a large number of OSSD projects have little influence, many projects a re unable to attract user interest. Therefore, it is important to understand the factors affecting OSSD project success as measured by project popularity. While technical factors such as license and compatibility with certain operating systems have a direct influence on the popularity of OSSD projects, development-related factors also have latent impacts on the popularity of OSSD projects. Therefore, we collect data on 445 projects and successfully build a structural equation model (SEM) which depicts the inherent relationships between development-related factors and OSSD project popularity.

Cross-language software similarity detection is inherently more challenging due to variations in language, application structures, support libraries used, and naming conventions. In this paper we propose a novel model, CroLSim, to detect similar software applications across different programming languages. We define a semantic relationship among cross-language libraries and API methods (both local and third party) using functional descriptions and a word-vector learning model. Our experiments show that CroLSim can successfully detect cross-language similar software applications, which outperforms all existing approaches (mean average precision rate of 0.65, confidence rate of 3.6, and 75% highly rated successful queries). Furthermore, we applied CroLSim to a source code repository to see whether our model can recommend cross-language source code fragments if queried directly with source code. From our experiments we found that CroLSim can recommend cross-language functional similar source code when source code is directly used as a query (average precision=0.28, recall=0.85, and F-Measure=0.40).

OSS project success is reflected in two forms: popularity and knowledge creation. Extending the extant OSS literature, we theorize a contingent role of interproject connectedness. In particular, we posit three points: (1) an OSS project with more structural holes achieves higher popularity; (2) an OSS project with fewer structural holes yields higher knowledge creation; and (3) these two relationships are enhanced by an increase in project maturity. Using a dataset longitudinally collected from SourceForge.net, we found that OSS projects with widespread connectedness are more popular. This is especially so for those OSS projects in the mid-mature stage. We also found that OSS projects with a cohesive network achieve higher knowledge creation, irrespective of their maturity. Findings from our study can contribute to OSS literature by identifying OSS projects that are more likely to be successful.","2021-03","2025-04-08 17:22:12","2025-04-08 17:22:12","","","","1","30","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","/Users/mgone/Zotero/storage/9QQM3RFB/Sutanto et al. - 2021 - The contingent role of interproject connectedness .pdf","","Open source software; Popularity; Maturity; Interproject connectedness; Knowledge creation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This surge in unmanned aerial vehicles has increased attention towards monitoring tasks in vital areas, such as urban spaces for security, surveillance or Internet of the Things applications. In this sense, we propose an open-source software-in-the-loop approach that integrates the complete navigation experience, accounting for potential wind-related effects, and providing realistic 3D modeling of scenarios encompassing open spaces in city landscapes. Our work introduces a wind perturbation estimation strategy, which models the wind effect as an external force along the Zaxis based on altitude variations from real flights. Validation was conducted using real data flights with a quadrotor aiding the navigation with Ardupilot and QgroundControl as a ground station. To complement the experiments we include a small test with a fixed-wing plane to asses the software-in-the-loop accuracy on larger trajectories. Results demonstrate successful tracking of altitude variations, yielding errors below 10% relative to the home position in experiments with average trajectory lengths of 150 m in two scenarios in Quito. The software-in-the-loop simulation aimed to replicate wind conditions specific to the date and time of real data acquisition, providing a platform to emulate possible improvements and assess UAV performance before deployment in actual missions. This research not only contributes to the optimization of monitoring capabilities but also serves as a valuable tool for assessing UAV missions in diverse and dynamic environments.","2024","2025-04-08 17:22:12","2025-04-08 17:22:12","","1453-1460","","","","","","","International Conference on Unmanned Aircraft Systems","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE ISSN: 2373-6720 Type: Proceedings Paper","","","","Ardupilot; Gazebo; ROS; Software-in-the-loop; wind perturbation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of orthopaedic and dental implants it was found that geometry and surface topography are crucial for short and long-term success of the implant, due to its effects in osseointegration. Properties of implant surfaces have been studied in the last decade in a concentrated effort to improve osseointegration process and implant success. Several researchers have proved that roughness of implant surface is related to healing time and integration between the implants and the bone, but the parameters on the surface creation are not fully controllable with current processes. In this work, computational algorithms are proposed for implant surface design in order to control the parameters required for this application. As a result it is presented an open-source software tool, called POMES - Porous and Modifications for Engineering Surfaces - , to design porous/roughness on top of surfaces in any geometry. Additionally, an example model was fabricated using POMES and additive manufacturing. (C) 2015 The Authors.

In the context of open source software, there is no single and non-controversial measure of usage, though. Still, one of the most used and readily available measure is data about projects downloads. Nevertheless, download counts and averages do not convey as much information as the patterns in the original downloads time series. In this research, we propose a method to increase the expressiveness of mere download rates by considering download patterns against software releases. We apply experimentally our method to the most downloaded projects of Source Forge's history crawled through the FLOSSMole repository. Findings show that projects with similar usage can have indeed different levels of sensitivity to releases, revealing different behaviors of users. Future research will develop further the pattern recognition approach to automatically categorize open source projects according to their download patterns.","2010","2025-04-08 17:22:12","2025-04-08 17:22:12","","252-267","","","319","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: Int Federat Informat Proc Work Grp 2 13 ISSN: 1868-4238 Type: Proceedings Paper","","/Users/mgone/Zotero/storage/N9YZA6EX/Rossi et al. - 2010 - Download Patterns and Releases in Open Source Soft.pdf","","Open source software projects; repository mining; software releases","","Agerfalk, P; Boldyreff, C; GonzalezBarahona, JM; Madey, GR; Noll, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are continuing debates over the future of software and, in particular, the competition between OSS and proprietary software. Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. The government environment is changing rapidly in areas as diverse as homeland security and social services. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied-especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-08 17:22:12","2025-04-08 17:59:19","","227-238","","2","44","","","","","","","","","","English","","","","","","","Place: 1 NEW ORCHARD ROAD, ARMONK, NY 10504 USA Publisher: IBM CORP Type: Article","","; ","https://media.proquest.com/media/hms/ORIG/5/G0cEE?_a=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&_s=SVgzekDe95rQdVHfJ2Zo%2BltJgw0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Systems+Journal&rft.atitle=The+value+of+open+standards+and+open-source+software+in+government+environments&rft.au=Simon%2C+K+D.&rft.aulast=Simon&rft.aufirst=K&rft.date=2005-04-01&rft.volume=44&rft.issue=2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=IBM+Systems+Journal&rft.issn=00188670&rft_id=info:doi/","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results indicated that contribution intention is significantly affected by social identity, which includes cognitive, affective and evaluative identity. In addition, the researchers found that the subjective norm has a negative effect on contribution intention.

Root characteristics like length, diameter and volume are critical to measure to understand plant and soil functions. RhizoVision Explorer is an open-source software designed to enable researchers interested in roots by providing an easy-to-use interface, fast image processing and reliable measurements. The default broken roots mode is intended for roots sampled from pots and soil cores, washed and typically scanned on a flatbed scanner, and provides measurements like length, diameter and volume. The optional whole root mode for complete root systems or root crowns provides additional measurements such as angles, root depth and convex hull. Both modes support providing measurements grouped by defined diameter ranges, the inclusion of multiple regions of interest and batch analysis. RhizoVision Explorer was successfully validated against ground truth data using a new copper wire image set. In comparison, the current reference software, the commercial WinRhizo (TM), drastically underestimated volume when wires of different diameters were in the same image. Additionally, measurements were compared with WinRhizo (TM) and IJ_Rhizo using a simulated root image set, showing general agreement in software measurements, except for root volume. Finally, scanned root image sets acquired in different labs for the crop, herbaceous and tree species were used to compare results from RhizoVision Explorer with WinRhizo (TM). The two software showed general agreement, except that WinRhizo (TM) substantially underestimated root volume relative to RhizoVision Explorer. In the current context of rapidly growing interest in root science, RhizoVision Explorer intends to become a reference software, improve the overall accuracy and replicability of root trait measurements and provide a foundation for collaborative improvement and reliable access to all.","2021-09-13","2025-04-08 17:22:13","2025-04-08 17:22:13","","","","6","13","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","Ground truth; phenomics; phenotyping; rhizosphere; root system architecture; traits","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Design/methodology/approach - Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. Findings - There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and “tribal knowledge” that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. Originality/value - The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-08 17:22:13","2025-04-08 17:58:09","","211-223","","2","28","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LIMITED Type: Article","","; ","https://media.proquest.com/media/hms/OBJ/qPQuT?_a=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&_s=R3D%2FTgQI5szaHaGdFb%2BVEn%2FrVUA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+economy+of+free+and+open+source+software+in+the+preservation+of+digital+artefacts&rft.au=Morrissey%2C+Sheila.&rft.aulast=Morrissey&rft.aufirst=Sheila&rft.date=2010-04-01&rft.volume=28&rft.issue=2&rft.spage=211&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2F07378831011047622","Open source software; Studies; Open source; Software tools; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Library And Information Sciences--Computer Applications; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As knowledge-based firms, COSS companies' success depends heavily on the interplay among intangible resources such as human capital, relational capital, structural capital, and software quality. To observe these relationships, we conducted a hypothesis-testing questionnaire-type survey involving 200 software development experts and professionals working at 60 multinational COSS companies. Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model. Therefore, COSS companies may need to prioritize software quality as it is the most critical variable impacting the success of COSS companies.","2022","2025-04-08 17:22:13","2025-04-08 17:22:13","","46490-46503","","","10","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","Open source software; Software; software quality; Companies; Knowledge management; Software quality; Commercial open-source software; company success; Integrated circuits; intellectual capital; Knowledge based systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The stability and longevity of this group of most active developers are crucial for the success of the project. While there has been prior work on identifying key individuals in open source development, little attention has been devoted to the identification of cross-cutting core individuals (boundary spanners) whose responsibilities span across different functional areas of open source development (e.g., who are involved both in development-centric activities and user-centric activities). To address this gap, we propose an approach to identify the core cross-cutting members and their roles within the community through analyzing email communication repositories. We use Social Network Analysis (SNA) tools to identify the most active core members in different forums (that have different focus such as Python-dev that focuses on language evolution and Python Lists that focus on user support), and their activities over time, thus identifying the core developers and their involvement in different community mailing lists. Based on the involvement of a core developer and the overall social structure of the network of core developers, we also present an approach for identifying a potential replacement for a community administrator that steps down. Using email repositories of six main Python forums as the case study domain, we computed several social network analysis metrics to characterize the core developers and their importance in the Python community.","2017","2025-04-08 17:22:13","2025-04-08 17:22:13","","308-317","","","","","","","Asia-Pacific Software Engineering Conference","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","ISSN: 1530-1362 Type: Proceedings Paper","","","","Social Network Analysis; Python; Open Source Software Development; Community Development","","Lv, J; Zhang, H; Hinchey, M; Liu, X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adopted a mixed method of structural equation modeling (SEM) and artificial neural network (ANN) to conduct data analysis. The results indicated that perceived justice, which includes distributive justice, procedural justice and interactional justice, has significant effects on trust and satisfaction, both of which further determine contribution intention.

Including function points and its variants, there are several size measures and corresponding measurement methods that can be used for effort estimation. However, in most of the projects, there is limited amount of information available in the early stages and significant effort is spent for size measurement and effort estimation with such methods. This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software. For this purpose, we consider open source project management and game software. We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., conceptual) and solution domain (i.e., design) models. The results reveal a high correlation between the number of conceptual classes in the problem domain model and the number of software classes constituting the corresponding software. The results suggest that it is possible to use problem domain descriptions in the early stages of software development projects to make plausible predictions for the size of the software.","2014","2025-04-08 17:22:13","2025-04-08 17:35:23","","81-84","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","/Users/mgone/Zotero/storage/A8NIPSY5/Ayyildiz and Kocyigit - 2014 - Correlations Between Problem Domain and Solution D.pdf","","conceptual models; linear regression model for size estimation; size estimation","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.","2011","2025-04-08 17:22:13","2025-04-08 17:32:07","","88-122","","1","12","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","; ","https://media.proquest.com/media/hms/OBJ/2tQAU?_a=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&_s=%2BlQ%2BKlAJsNgb7RBVOrEzuNfGPv8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Adopting+Free%2FLibre%2FOpen+Source+Software+Practices%2C+Techniques+and+Methods+for+Industrial+Use*&rft.au=Torkar%2C+Richard%3BMinoves%2C+Pau%3BGarrig%C3%B3s%2C+Janina.&rft.aulast=Torkar&rft.aufirst=Richard&rft.date=2011-01-01&rft.volume=12&rft.issue=1&rft.spage=88&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Advantages; Information systems; Studies; Open source; Software; Open-source software; Linux; Methods; Computers--Information Science And Information Theory; Models; Software development; Software quality; 9130:Experiment/theoretical treatment; Public domain; 51321:Software Publishers; Software industry; Industrial development; Industrialisation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Creating this technology requires designing, implementing, debugging and testing software applications on a continual basis. Furthermore current software development is typically performed in a distributed environment involving many developers. While the use of open-source software may create collaborative communities that enhance overall technology exchange, it does nothing directly to manage change nor does it address the quality of the underlying software. This paper describes a software development process that has proven vital to the success of the widely used open-source toolkits ITK (itk.org) and VTK (vtk.org). This process facilitates cross-platform development, includes automatic documentation generation, integrates continuous testing, and posts the results of the process on publicly accessible web pages. The net result is that a responsive feedback loop is created between the developers in the community and automated processes to measure software quality. With this process software converges towards better software as long as the process is enforced. The tools described here are open-source and available for use in academic and commercial applications.","2004","2025-04-08 17:22:13","2025-04-08 17:22:13","","648-651","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Specific and practical steps are recommended to provide a foundation for graduate students, supervisors, administrators, and members of the OSS community to help overcome these obstacles. In conclusion, the objective of these recommendations is to describe a possible framework that individuals from across the scientific community can adapt to their needs and facilitate a sustainable feedback loop between graduate students and OSS.","2020-05-07","2025-04-08 17:22:13","2025-04-08 17:22:13","","289-303","","","5","","","","","","","","","","English","","","","","","","Place: 65 AURIGA DR, SUITE 203, OTTAWA, ON K2E 7W6, CANADA Publisher: CANADIAN SCIENCE PUBLISHING Type: Article","","","","open-source software; academic culture; computational research; graduate students","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In addition to this rapid growth in the population of older adults, there is also rapid growth of free/open source software projects (FOSS). Despite the increasing diversity of FOSS's user base, FOSS's developer base is quite homogeneous, comprised mainly of 20-something year old males. This lack of diversity could be detrimental to the community, as many voices of end users are not heard. I aim to increase age diversity in free/open source software communities by investigating how to involve older adults.

Dolores; Bueno, Salvador","ORGANIZATIONAL AND MOTIVATIONAL FACTORS FOR IMPLEMENTING ENTERPRISE SOLUTIONS BASED ON OPEN SOURCE SOFTWARE","RELATIONAL DATABASES AND OPEN-SOURCE SOFTWARE DEVELOPMENTS","978-1-61668-436-5","","","","Organizations implement Enterprise solutions, mainly Enterprise Resource Planning (ERP) systems, with the aim of attaining operational efficiency and the incorporation into new markets through the real time information flow control of the entire organization. However, ERP systems are complex tools, particularly for small and medium size enterprises (SMEs). For this reason, new ERP configurations have arisen, such as Open Source Software-ERP (OSS-ERP). In the website Sourceforge.net, we can identify 2058 projects about OSS-ERP, although all of them have not had an impact on the ERP market. This data is indicative of the increasing relevance of this enterprise solution for organizations. At this moment, the OSS-ERP vendors with a greater diffusion are Compiere, Openbravo, Abanq (previously FacturaLux), ERP5, Tiny ERP, Fisterra, OFBiz, SQL-Ledger and WebERP. OSS-ERP has three relevant advantages for organizations: (1) increased adaptability, (2) decreased reliance on a single supplier, (3) reduced costs. OSS-ERP generally include the necessary functions to integrally manage all the activities of a company. Due to their high flexibility, these tools can be adapted to the client's specific needs. Furthermore, as OSS-ERP are based on open software technologies, organizations do not have to pay licenses or exclusive contracts. With the collaboration of partners, OSS-ERP vendors receive benefits for the support services. Research in OSS has identified individual personal motives for using OSS software, analyzing specific OSS solutions, or the OSS movement itself. The literature in Enterprise solutions has also analyzed the main organizational factors for successfully implementing an ERP system. However, OSS-ERP is a research topic barely analyzed by the literature. This paper's aim is to specifically focus on the organizational and motivational factors for implementing OSS-ERP. The authors developed a research work for testing the impact of organizational and motivational factors on the implementation of OSS-ERP by means of a survey of organizations with OSS-ERP and OSS-ERP users.","2010","2025-04-08 17:22:13","2025-04-08 17:22:13","","257-273","","","","","","","Computer Science Technology and Applications","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Taylor, JR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers' positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-07","2025-04-08 17:22:14","2025-04-08 17:22:14","","","","4","32","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","/Users/mgone/Zotero/storage/RJY456KT/Joblin et al. - 2023 - Hierarchical and Hybrid Organizational Structures .pdf","","hierarchy; developer networks; Open-source software projects; organizational structure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to meet user needs and functional changes, open-source software continuously improves its software quality through successive releases. Due to the iterative development process of open-source software, open-source software testing also requires continuous learning to understand the changes in the software. Therefore, the fault detection process of open-source software involves a learning process. Additionally, the complexity and uncertainty of the open-source software development process also lead to stochastically introduced faults when troubleshooting in the open-source software debugging process. Considering the phenomenon of learning factors and the random introduction of faults during the testing process of open-source software, this paper proposes a reliability modeling method for open-source software that considers learning factors and the random introduction of faults. Least square estimation and maximal likelihood estimation are used to determine the model parameters. Four fault data sets from Apache open-source software projects are used to compare the model performances. Experimental results indicate that the proposed model is superior to other models. The proposed model can accurately predict the number of remaining faults in the open-source software and be used for actual open-source software reliability evaluation.","2024-01","2025-04-08 17:22:14","2025-04-08 17:22:14","","","","2","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source software; learning factors; software reliability model; stochastic differential equation; stochastically introduced faults","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many projects leverage the contribution of outsiders, and the sustainability of the project relies on retaining some of these newcomers. This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review; (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects; (iii) 24 responses to a questionnaire sent to 9 OSS projects; and (iv) semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practitioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteristics, reception issues, orientation, technical hurdles, and documentation problems. We could observe recurrent barriers evidenced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-08 17:22:14","2025-04-08 17:55:18","","51+","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Univ Fed Alagoas; Ufal; CAPES; Conselho Nacl Desenvolvimento Cientifico & Tecnologico; Ines; Google; Inst Fed Alagoas; Aloo Telecom; Alagoas Governo Estado, Secretaria Estado Turismo; Maceio Convent & Visitors Bur; Soc Brasileira Computacao; Josi Mendes Consultoria & Eventos; Transamerica Turismo; IEEE Comp Soc Type: Proceedings Paper","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions.

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context. We conclude by discussing governance issues related to the disciplined use and reuse of open source and areas for further improvements.","2022","2025-04-08 17:22:14","2025-04-08 17:54:47","","154-163","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Siemens; Pure Syst; Assoc Comp Machin; Graz Univ Tech; Itk Engn; Combeenation; Select Arts; Stream Diver; Hitec; Stadt Graz.at; Elsevier Journal Syst & Software Type: Proceedings Paper","","","","open source software; dependencies; NPM; DevSecOps; maven; Maven","","Felfernig, A; Fuentes, L; Cleland-Huang, J; Assuncao, WKG; Falkner, A; Azanza, M; Luaces, MAR; Bhushan, M; Semini, L; Devroey, X; Werner, CML; Seidl, C; Le, VM; Horcas, JM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A total of 220 patients (1020 observations) who received vancomycin TDM services were included in the dataset. A population PK analysis was performed using non-linear mixed effects modeling, and a covariate evaluation was conducted. A two-compartment model with first-order elimination best explained the vancomycin PK, with estimates of 2.82 L/h, 31.8 L, 11.7 L/h, and 75.4 L for CL, V-1, Q, and V-2, respectively. In the covariate analysis, weight correlated with the volume of the peripheral compartment, and creatinine clearance, hemodialysis, and continuous renal replacement therapy treatments contributed to the clearance of vancomycin. The results show the clear need to optimize the PK parameters used for TDM in Korean patients. Specifically, V-1 should be smaller for Korean patients, and renal replacement therapies should be considered in TDM practice.

The techniques for performing inspections have been well studied in industry; in OSS development, peer reviews are less well understood. We examine the two peer review techniques used by the successful, mature Apache server project: review-then-commit and commit-then-review. Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects. We provide a comparison of the two Apache review techniques as well as a comparison of Apache review to inspection in an industrial project. We conclude that Apache reviews can be described as (1) early, frequent reviews (2) of small, independent, complete contributions (3) conducted asynchronously by a potentially large, but actually small, group of self-selected experts (4) leading to an efficient and effective peer review technique.","2008","2025-04-08 17:22:14","2025-04-08 17:22:14","","541-550","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: ACM SIGSOFT; IEEE CSE; Univ Paderborn; Univ Leipzig; SIEMENS; Zuhlke; Adesso; Deutsch Telekom Labs; sd&m; Werum; Microsoft Res; IBM; i nemis; dSPACE Type: Proceedings Paper","","","","Open source software; Peer review; Inspection; Mining software repositories (email)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conduct an explorative case study at Siemens AG. Siemens introduced a formal template process which can be adapted by the organizational units according to their demands. Results show that the extent to which the process is implemented depends on the level of closeness to core intellectual property of the organizational unit and the intensity of the involvement in OSS communities.

An Open Source Software Development (OSSD) process model to enhance the survivability of OSSD projects is needed. This research uses the grounded theory approach to derive a Phase-Role-Skill-Responsibility (PRSR) OSSD process model. The three OSSD process phases – Launch Stage, Before the First Release, and Between Releases – address the characteristics of the OSSD process as well as factors that influence the OSSD process. In the PRSR model, different roles/actors are required to have different skills and responsibilities corresponding to each of the three OSSD process phases.

It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects.","2024-05","2025-04-08 17:22:14","2025-04-08 17:22:14","","","","5","36","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","software evolution; assessment model; open source software engineering; software resilience","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We empirically investigate different types of conflict in Free and Open Source Software development teams, their antecedents and impact on developers' sustained participation. Following a survey of 222 FOSS developers, we find conflict to have an overall negative effect on developer retention. Furthermore, different types of conflict have varying impact on outcomes. In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes. Though we find structural factors like task interdependence and geographical distribution increase overall conflict levels in FOSS teams, participatory decision-making and a transformational leadership style have an ameliorating effect.

The study investigates factors that affect the selection of software for public sector information systems with, an emphasis on how Free and Open Source Software ( FOSS) is used and could be used in such projects. The objectives of the study are as follows. The study aims to identify factors that affect the adoption of Software in Sri Lankan government sector projects. In addition to this it identifies features that are considered as important in such large Information Systems, and how they relate to Open Source Software adoption in the context of the public sector in Sri Lanka. The findings are analyzed and suitable recommendations are presented for better selection of software in the public sector. The work is important as it identifies and highlights factors that affect the choice of software in the public sector. This is important for several categories of people. It is of importance to the strategic management and policy makers to know what drives the information system procurement decisions in order to make more relevant policies and guidelines that are congruent with the needs in government sector departments. It is useful when advocating new technologies and information systems. This is especially true when advocating the use of Free and Open Source software for the use in the public sector in a wholesome and sustainable manner. The research is also important to software vendors and solution providers to the public sector in identifying what factors need to be taken in to account when bidding for public sector IS projects. The research is of a qualitative nature. It consists of multiple case studies of selected government sector departments and projects in Sri Lanka. The study investigates information systems developed by internal staff, developed by external consultants, procured systems, system implementation via private public partnerships (PPP) and projects guided by the Information and Communication Technology Agency (ICTA) of Sri Lanka. Data was gathered through interviews of staff at different levels of selected government sector Information Systems projects. The data was comparatively analyzed on a case by case basis to identify common patterns and trends among the investigated organizations and projects. The identified factors affecting the choice of software include the cost, technical specifications, bidder's expertise in selected technology and user's expertise in selected technology amongst other factors described in the full paper. The study identifies patterns between the choice of software - FOSS or non FOSS, and these identified factors. Based on these, recommendations are given to adopt and benefit from the use of FOSS in public sector enterprise level software projects.","2011","2025-04-08 17:22:15","2025-04-08 17:22:15","","239-252","","","","","","","","","","","ACAD CONFERENCES LTD","CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND","English","","","","","","","Type: Proceedings Paper","","","","free and open source software; government; enterprise software; software adoption","","Grant, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the differential impacts of such social influence on developers' initial and sustained participation behaviors were largely overlooked in previous research. We empirically studied the impacts of two social influence mechanisms-word-of-mouth (WOM) and observational learning (OL)-on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.","2021-09","2025-04-08 17:22:15","2025-04-08 17:36:26","","1133-1147","","9","72","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","/Users/mgone/Zotero/storage/46WSQ75S/Yang et al. - 2021 - Differential impacts of social influence on initia.pdf; ","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Science+and+Technology&rft.atitle=Differential+impacts+of+social+influence+on+initial+and+sustained+participation+in+open+source+software+projects&rft.au=Yang%2C+Xuan%3BLi%2C+Xiao%3BHu%2C+Daning%3BWang%2C+Harry+Jiannan.&rft.aulast=Yang&rft.aufirst=Xuan&rft.date=2021-09-01&rft.volume=72&rft.issue=9&rft.spage=1133&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Science+and+Technology&rft.issn=23301635&rft_id=info:doi/10.1002%2Fasi.24481","Open source software; Learning; Platforms; Library And Information Sciences; Social research; Open source; Software; Open-source software; Social influence; Social Influences; Social networks; Software development; Public domain; Software Projects; Software development tools; Modeling (Psychology); Observational Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, integrating external and internal sources of social capital is challenging and identifying appropriate integration strategies is crucial for the success of such endeavors. This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success. We also show that when development environment difference is moderate, the impact of role diversity is the most positive. We present the implications of these findings for theory and practice.","2018-09","2025-04-08 17:22:15","2025-04-08 17:22:15","","237-256","","3","27","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Success; Diversity; Open source projects; Connectedness; Development difference; Participant difference","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Abstractions of MPL systems are derived as finite-state transition systems. A transition system is obtained first by partitioning the state space of the MPL system into finitely many regions and then by associating a unique state of the transition system to each partitioning region. Relations among the states of the transition system are then set up based on the underlying dynamical transitions between the corresponding partitioning regions of the MPL state space. In order to establish formal equivalences, the obtained finite abstractions are proven either to simulate or to bisimulate the original MPL system. The approach enables the study of general properties of the original MPL system formalized as logical specifications, by verifying them over the finite abstraction via model checking. The article presents a new, extended and improved implementation of a software tool (available online) for the discussed formal abstraction of MPL systems, and is tested on a numerical benchmark against a previous version.","2016-03","2025-04-08 17:22:15","2025-04-08 17:22:15","","109-145","","1, SI","26","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Bisimulations; Difference-bound matrices; Discrete-event systems; Max-plus algebra; Model abstractions; Model checking; Piece-wise affine systems; Transition systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from ultra-high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically. Efficient analysis to find potentially toxic compounds in alternative foods and resilient foods. Identification of potentially unsafe products without the use of live animal testing.

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 7 0 0; 0 0 0 bug reports obtained from the BUGZILLA installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3% with an associated recall of 38.9%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.","2013","2025-04-08 17:22:15","2025-04-08 17:22:15","","1032-1041","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM Special Interest Grp Software Engn; IEEE Comp Soc; Tech Council Software Engn Type: Proceedings Paper","","","","","","Notkin, D; Cheng, BHC; Pohl, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is time-consuming because of the bioinformatics processes involved, including sequence trimming, consensus sequence generation, and public database searches. We developed a simple and fully automated software that enabled species-level identification of NTM from trace files, SnackNTM (https://github.com/Young-gonKim/SnackNTM). Methods: JAVA programing language was used for software development. The SnackNTM diagnostic algorithm utilized 16S rRNA gene sequences, according to the Clinical & Laboratory Standards Institute guidelines, and an rpoB gene region was adjunctively utilized to narrow down the species. The software performance was validated using trace files of 234 clinical cases, comprising 217 consecutive cases and 17 additionally selected cases of unique species. Results: SnackNTM could analyze multiple cases at once, and all the bioinformatics processes required for sequence-based NTM identification were automatically performed with a single mouse click. SnackNTM successfully identified 95.9% (208/217) of consecutive clinical cases, and the results showed 99.0% (206/208) agreement with manual classification results. SnackNTM successfully identified all 17 cases of unique species. In a processing time comparison test, the analysis and reporting of 30 cases, which took 150 minutes manually, took only 40 minutes with SnackNTM. Conclusions: SnackNTM is expected to reduce the workload for NTM identification, especially in clinical laboratories that process large numbers of cases.","2022-03","2025-04-08 17:22:16","2025-04-08 17:22:16","","213-248","","2","42","","","","","","","","","","English","","","","","","","Place: A505-ASTERIUM SEOUL, 372 HANGANG-DAERO, YONGSAN-GU, SEOUL, 04323, SOUTH KOREA Publisher: KOREAN SOC LABORATORY MEDICINE Type: Article","","","","16S rRNA gene; Nontuberculous mycobacteria; NTM identification; rpoB; SnackNTM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. Conclusion: We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care. (C) 2009 Elsevier Ireland Ltd.

Objective: This work is aimed at studying the communication functions of bug comments and their associations with fast and complete bug fixing in OSS development. Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist. The results of this work could be used to improve corrective tasks in OSS development and some other specific linguistic aspects should be studied in detail in OSS communities.","2021-08","2025-04-08 17:22:16","2025-04-08 17:22:16","","","","","136","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Machine learning; Bug fixing; Communication function; Corrective maintenance; Issue Tracking System; Open Source Software development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity. (C) 2019 The Authors.

Here we describe the Brain Modeling ToolKit (BMTK), a software suite for building models and performing simulations at multiple levels of resolution, from biophysically detailed multi-compartmental, to point-neuron, to population-statistical approaches. Leveraging the SONATA file format and existing software such as NEURON, NEST, and others, BMTK offers a consistent user experience across multiple levels of resolution. It permits highly sophisticated simulations to be set up with little coding required, thus lowering entry barriers to new users. We illustrate successful applications of BMTK to large-scale simulations of a cortical area. BMTK is an open-source package provided as a resource supporting modeling-based discovery in the community.","2020-11","2025-04-08 17:22:16","2025-04-08 17:22:16","","","","11","16","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications. By our plug-in, information about measured physiological processes can be obtained and transferred into clinical practice.","2013-04","2025-04-08 17:22:16","2025-04-08 17:22:16","","344-352","","2","26","","","","","","","","","","English","","","","","","","Place: 233 SPRING ST, NEW YORK, NY 10013 USA Publisher: SPRINGER Type: Article","","","","Algorithms; Image processing; Computer-assisted; Magnetic resonance imaging; Perfusion","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In many Open Source Softoware Development (OSSD) communities, DM processes lie buried amongst vast amounts of publicly available data. Hidden within this data lie the rationale for decisions that led to the evolution and maintenance of software products. While there have been some efforts to extract DM processes from publicly available data, the rationale behind `boo' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million mails. This paper makes two main contributions. First. it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second. it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven. bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement).

To estimate whether a state ofsocio-technical congruenceis achieved, which is associated with software quality and project success, we assess the alignment of collaboration and communication in such software projects in terms ofcoordination requirements. By means of an empirical study on a substantial set of large-scale open-source software projects-the development histories of all projects sum up to over 180 years-we aim at shedding light on this issue. To this end, to take a more semantic view on this phenomenon in comparison to previous work, we do not only identify coordination requirements arising from files and functions only, but also those arising from features. We found that open-source developers fulfill coordination requirements intentionally, but mostly those coordination requirements that arise from coupled source-code artifacts, while they resolve simpler ones independently. Furthermore, neither of the considered abstraction levels of source-code artifacts (files, functions, features) is more suitable to construct coordination requirements with respect to their fulfillment. This finding strongly indicates that features do not play an as important role in the development process as expected and commonly believed by the research community in the area of feature-oriented and feature-driven development. Finally, we identified notable evolutionary trends in the fulfillment of coordination requirements and showed that far-reaching social events (such as organizational issues) have a huge impact on their fulfillment, both negatively and positively. The key findings of our empirical study are that socio-technical relations are important to understand open-source development communities and that the incorporation of different abstraction levels for developer collaboration does yield important insights to further improve the evolution in open-source software projects.","2020-11","2025-04-08 17:22:16","2025-04-08 17:22:16","","4379-4426","","6","25","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Socio-technical congruence; Codeface; Configurable systems; Coordination requirements; Coronet; Feature-oriented software development; Features; Open-source software systems; Social-network analysis; Software product lines","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While existing research in the area has offered a rich foundation, we know little about how developers' perceptions of fit with the project environment may be moderated by the sense of ownership they have toward the project and how it may impact their turnover intentions. Using survey data from 574 GitHub developers, we tested a model to examine the impact of Person-Organization fit and psychological ownership on developers' turnover intentions.

This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 %, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 %. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic. These insights provide various stakeholders, including individuals, organizations, and policymakers, with vital knowledge to prepare for future disruptions, foster sustainable resilience, and adeptly navigate the evolving landscape of remote work in a postpandemic world.","2023-12","2025-02-27 03:12:47","2025-04-17 15:38:12","","","","10","52","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","/Users/mgone/Zotero/storage/VAVFS56S/Hu et al. - 2023 - The impacts of lockdown on open source software co.pdf; /Users/mgone/Zotero/storage/GCPFIJ5M/S0048733323001695.html","","Open source software; COVID-19; Face-to-face interactions; Lockdown; Work productivity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although it is well-known that OSS contributors have different involvements (e.g., while some developers drive the project, there is a long tail of peripheral developers), little is known about how the contributor's degree of participation can influence the build status of an OSS project. Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result. Our results suggest that there is no representative difference between their build success (they are similar in 85% of the analyzed projects), meaning that being a casual contributor is not a strong indicator for creating failing builds. Also, factors like the size of their contributions and the number of project configurations (jobs) have the potential of impacting the build success.","2017","2025-04-08 17:22:17","2025-04-08 17:39:31","","475-478","","","","","","","IEEE International Working Conference on Mining Software Repositories","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISSN: 2160-1852 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when “simple stupid bugs” were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub. Leveraging a statistical survival model and other non-parametric statistical tests, we found that there were two main categories of categorical variables that affect a bug's life; Time Factors and Author Factors. We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time. These findings will provide vital insight to help the open-source community mitigate the abundance of code and can be used in future research to aid in bug-finding programs.","2023-03","2025-04-08 17:22:17","2025-04-08 17:22:17","","","","5","13","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","survival analysis; bug fixes; one-line bugs; statistical analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

EBA involves the use of psychometric instruments to gather data that can inform clinical decision-making, inform policymakers, and serve as a basis for research and quality management. Despite its potential, EBA is often hindered by barriers such as workload and cost, leading to its underutilization. Regarding low- and middle-income countries (LMIC), the implementation of EBA is recognized as a key strategy to address and close the prevalent mental health treatment gap.To simplify the application of EBA including in LMIC, an international team of researchers and practitioners from Tanzania, Kosovo, Chile, and Switzerland developed the Mental Health Information Reporting Assistant (MHIRA). MHIRA is an open-source electronic health record that streamlines EBA by digitising psychometric instruments and organising patient data in a user-friendly manner. It provides immediate and convenient reports to inform clinical decision-making.The current article provides a comprehensive overview of the features and technical details of MHIRA, as well as insights from four implementation scenarios. The experience gained during the implementations as well as the user-feedback suggests that MHIRA has the potential to be successfully implemented in a variety of clinical contexts and simplify the use of EBA. However, further research is necessary to establish its potential to sustainably transform healthcare services and impact patient outcomes.In conclusion, MHIRA represents an important step in promoting the widespread adoption of EBA in mental health. It offers a promising solution to the barriers that have limited the use of EBA in the past and holds the potential to improve patient outcomes and support the ongoing efforts to address gaps in mental health care.","2023-10-02","2025-04-08 17:22:17","2025-04-08 17:22:17","","","","1","23","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Software; Open-source; Digital; Electronic health record; Evidence-based assessment; Implementation sciences; Low- and middle-income countries; Mental health","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context.

Although some of the hosted projects are growing and have many developers, most projects are organized by a few developers and face difficulties in terms of sustainability. OSS projects depend mainly on volunteer developers, and attracting and retaining these volunteers are major concerns of the project stakeholders. To investigate the population structures of OSS development communities in detail and conduct software analytics to obtain actionable information, we apply a demographic approach. Demography is the scientific study of population and seeks to identify the levels and trends in the size and components of a population. This paper presents a case study, investigating the characteristics of the population structures of OSS projects on GitHub, and shows population projections generated with the well-known cohort component method. We found that there are four types of population structures in OSS development communities in terms of experiences and contributions. In addition, we projected the future population accurately using a cohort component population projection method. This method predicts a population of the next period using a survival rate calculated from past population. To the best of our knowledge, this is the first study that applied demography to the field of OSS research. Our approach addressing OSS-related problems based on demography will bring new insights, since studying population is novel in OSS research. Understanding current and future structures of OSS projects can help practitioners to monitor a project, gain awareness of what is happening, manage risks, and evaluate past decisions.","2016-05","2025-04-08 17:22:17","2025-04-08 17:22:17","","1304-1315","","5","E99D","","","","","","","","","","English","","","","","","","Place: KIKAI-SHINKO-KAIKAN BLDG, 3-5-8, SHIBA-KOEN, MINATO-KU, TOKYO, 105-0011, JAPAN Publisher: IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG Type: Article","","","","OSS; demography; software development communities; software population pyramids","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The gains obtained from the reuse of community-developed libraries may be offset by the cost of detecting, assessing, and mitigating their vulnerabilities in a timely manner. In this paper we present a novel method to detect, assess and mitigate OSS vulnerabilities that improves on state-of-the-art approaches, which commonly depend on metadata to identify vulnerable OSS dependencies. Our solution instead is code-centric and combines static and dynamic analysis to determine the reachability of the vulnerable portion of libraries used (directly or transitively) by an application. Taking this usage into account, our approach then supports developers in choosing among the existing non-vulnerable library versions. Vulas, the tool implementing our code-centric and usage-based approach, is officially recommended by SAP to scan its Java software, and has been successfully used to perform more than 250000 scans of about 500 applications since December 2016.

For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.","2010","2025-04-08 17:22:17","2025-04-08 17:22:17","","","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","ISSN: 1063-6773 Type: Proceedings Paper","","","","software metrics; software quality; open-source software; Software maintenance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, even after 20 years of intense research in this field, perfusion imaging still remains a research tool without a broad clinical usage. One problem is the lack of standardization in technical aspects which have to be considered for successful quantitative evaluation; the second problem is a lack of tools that allow a direct integration into the diagnostic workflow in radiology. Results: Five compartment models, namely, a one compartment model (1CP), a two compartment exchange (2CXM), a two compartment uptake model (2CUM), a two compartment filtration model (2FM) and eventually the extended Toft's model (ETM) were implemented as plugin for the DICOM workstation OsiriX. Moreover, the plugin has a clean graphical user interface and provides means for quality management during the perfusion data analysis. Based on reference test data, the implementation was validated against a reference implementation. No differences were found in the calculated parameters. Conclusion: We developed open source software to analyse DCE-MRI perfusion data. The software is designed as plugin for the DICOM Workstation OsiriX. It features a clean GUI and provides a simple workflow for data analysis while it could also be seen as a toolbox providing an implementation of several recent compartment models to be applied in research tasks. Integration into the infrastructure of a radiology department is given via OsiriX. Results can be saved automatically and reports generated automatically during data analysis ensure certain quality control.","2016-01-14","2025-04-08 17:22:17","2025-04-08 17:22:17","","","","","16","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Open source software; Data analysis; Workflow; Compartment models; Dce-mri","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Due to their cell-mimicking properties, GUITs have become a widespread experimental tool in synthetic biology to study membrane properties and cellular processes. In stark contrast to the experimental progress, quantitative analysis of GUV microscopy images has received much less attention. Currently, most analysis is performed either manually or with custom-made scripts, which makes analysis time-consuming and results difficult to compare across studies. To make quantitative GUV analysis accessible and fast, we present DisGUVery, an open-source, versatile software that encapsulates multiple algorithms for automated detection and analysis of GUVs in microscopy images. With a performance analysis, we demonstrate that DisGUVery's three vesicle detection modules successfully identify GUVs in images obtained with a wide range of imaging sources, in various typical GUV experiments. Multiple predefined analysis modules allow the user to extract properties such as membrane fluorescence, veside shape, and internal fluorescence from large populations. A new membrane segmentation algorithm facilitates spatial fluorescence analysis of nonspherical vesicles. Altogether, DisGUVery provides an accessible tool to enable high-throughput automated analysis of GUVs, and thereby to promote quantitative data analysis in synthetic cell research.","2023-01-20","2025-04-08 17:22:18","2025-04-08 17:22:18","","120-135","","1","12","","","","","","","","","","English","","","","","","","Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC Type: Article","","","","open-source software; bottom-up reconstitution; giant unilamellar vesicles; image analysis; object detection; synthetic cell","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm's practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems. (C) 2017 The Authors.

Mentoring allows contributors to improve their technical skills and learn about the protocols and cultural norms of the project. However, mentoring has its challenges: mentors sometimes feel unappreciated, and mentees may have mismatched interests or lack interpersonal skills. Existing research has investigated the different challenges of mentoring in different OSS contexts, but we lack a holistic understanding. Objective: A comprehensive understanding of the current practices and challenges of mentoring in OSS is needed to implement appropriate strategies to facilitate mentoring. Method: This study presents a systematic literature review investigating how literature has characterized mentoring practices in OSS, including their challenges and the strategies to mitigate them. We retrieved 232 studies from four digital libraries. Out of these, 21 were primary studies. Using this, we performed backward and author snowballing, adding another 27 studies. We conducted a completeness check by reviewing the references of the 4 most relevant primary studies, which resulted in us adding 1 additional study. We then conducted a full-text review and evaluated the studies using a set of criteria; as a result, 10 papers were excluded. We then employed an open-coding approach to analyze, aggregate, and synthesize the selected studies. Results: We reviewed 39 studies to investigate the different facets of mentoring in OSS, encompassing motivations, goals, channels, and contributor dynamics. We then identified 13 challenges associated with mentoring in OSS, which fall into three categories: social, process, and technical. We also present a quick-reference strategy catalog to map these strategies to challenges for mitigation. Conclusions: Our study serves as a guideline for researchers and practitioners about mentoring challenges and potential strategies to mitigate these challenges.","2024-07","2025-04-08 17:22:18","2025-04-08 17:22:18","","","","","171","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source; Mentoring; Literature review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.","2021-09-25","2025-04-08 17:22:18","2025-04-08 17:22:18","","","","1","13","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Deep learning; De novo drug design; Graphical user interface; Molecule generation; Web application","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially influence how a new OSS project chooses among such licenses and how the experiences of the project manager of a new OSS project with particular licenses affects its susceptibility to this social influence. We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Our results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its inter-project social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. We also find that managers of new projects who have been members of more successful prior OSS projects and who have greater depth and diversity, of experience in the OSS community are less susceptible to social influence. Finally, we find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license. These results have implications for research on innovation adoption and diffusion, open source software licensing, and the governance of economic exchange.","2013-09","2025-04-08 17:22:18","2025-04-08 17:22:18","","539-560","","3","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","/Users/mgone/Zotero/storage/K95ZF69M/Singh and Phelps - 2013 - Networks, Social Influence, and the Choice Among C.pdf","","social networks; social influence; innovation adoption and diffusion; open source software license","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

MOOC is a course-Open, Participatory, Distributed and Lifelong networked learning. It has facility of various courses, with start, end dates and participants. It's a way to connect and collaborate while developing digital skills an engage in a learning process. It is an EVENT around which people who care about a topic can gather and talk about it in a structured way. MOOC can promote the network learning for lifelong. People that have reputations for interesting skills and innovative thinking besides a topic, collaborate by opening an online course covering that topic. Anyone can join it. In a MOOC we can choose what we want to do, how we want to participate and we can decide if we have been successful, just like an existing atmosphere. Tutorials on almost all the Free open source are run by Spoken tutorials which is available on the internet and is provided by the team of spoken tutorial project. In this analysis we have mentioned all the steps of spoken tutorial courses and have took a survey from computer engineering students who are currently being taught Linux as their course laboratory and subject. This survey contained the questions related to the spoken tutorial for FOSS Linux and mode to organize the workshop.","2013","2025-04-08 17:22:18","2025-04-08 17:22:18","","411+","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Educ Soc Type: Proceedings Paper","","","","FOSS; survey; Linux; MOOC; Spoken-Tutorial","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding contributor behavior within large Free/Open Source Software projects - A socialization perspective","JOURNAL OF STRATEGIC INFORMATION SYSTEMS","","0963-8687","10.1016/j.jsis.2017.03.001","","Attracting new contributors is a necessary but not a sufficient condition, to ensure the survival and long-term success of Free/Open Source Software (FOSS) projects. The well-being of a FOSS project depends on the turning of project newcomers into `good contributors' that is to say into individuals that substantially contribute to the project - but also that perform citizenship behaviors that protect and nurture its community. This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness. Theoretical and practical implications are discussed. (C) 2017 Elsevier B.V.

The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the “institutional design” of the ASF could aid in producing the OSS public good by providing services that projects require.","2022","2025-04-08 17:22:19","2025-04-08 17:22:19","","64-77","","1","16","","","","","","","","","","English","","","","","","","Place: Unit 3N, 6 Osborn Street, LONDON, E1 6TD, ENGLAND Publisher: UBIQUITY PRESS LTD Type: Article","","","","institutional analysis; open source software; commons; public goods; cost-benefit analysis; common-pool resource; policy analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been in-stitutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous se-curity in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed secu-rity controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption en-ables businesses to deliver time-to-market security ready applications and services with accelerated ve-locity and sustainable agility in a cost-effective way.

The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context.

Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a “safety net” for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and “living” design documentation. Rapid-cycle development or “agile” methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as “executable requirements.” Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the “executable requirements” are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.","2018-06","2025-04-08 17:22:19","2025-04-08 17:22:19","","80-90","","2","6","","","","","","","","","","English","","","","","","","Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC Type: Article","","","","agile methods; clinical decision support systems; electronic health records; software validation; software verification; test driven development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study. We reveal that Landsat 8 data combined with texture analysis can accurately detect these artificial landmarks across the heterogeneous environment of OROAFR; 75.68% of artificial water points within the site were successfully identified and false positive detection rate was minimal at 7.69%. The methodological framework developed for this work, based on the treatment of freely available satellite data using open source software, adds to other works attempting to help monitor threats to biodiversity in desert ecosystems, enabling up-to-date information on the level of anthropogenic activities in these habitats to be easily and regularly collected.","2015-10","2025-04-08 17:22:20","2025-04-08 17:22:20","","61-72","","1","1","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN, NJ 07030 USA Publisher: WILEY Type: Article","","","","open source; Anthropogenic activity; deserts; land use change; remote sensing; satellite data","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

New technological innovations have greatly facilitated e-learning and have made it conducive to those who can afford. Developed countries have significantly benefited from these innovations whereas developing economies are still battling with the many challenges that have hindered e-learning success. The advent of Web 2.0 and Free Open Source Software (FOSS) would have been seen as the breakthrough for the developing economies to embrace e-learning. However, many factors still impede the utilization of these technologies for e-learning. The major objective of this paper is to discuss the factors that hinder institutions from utilizing Web 2.0 and FOSS for e-learning. Content analysis was used to evaluate the factors that had been identified in literature and to tally them according to their frequency. 36 factors were deduced and analyzed using structural equation modeling (SEM) method. Results indicated that technological factors predominantly impact on the utilization of Web 2.0 and FOSS for e-learning. The framework of this study serves as a guideline in the use of Web 2.0 and FOSS technologies for e-learning.","2012","2025-04-08 17:22:20","2025-04-08 17:22:20","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","","","Structural equation modeling; e-learning in developing countries; Pedagogy 2.0; Web 2.0/FOSS technologies","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On these platforms, various information is obtained from developer activities that can then be used as developer metrics to solve a variety of challenges. In this study, we proposed new developer metrics extracted from the issue, commit, and pull request activities of developers on GitHub. We created developer metrics from the individual activities and combined certain activities according to some common traits. To evaluate these metrics, we created an item-based project recommendation system. In order to validate this system, we calculated the similarity score using two methods and assessed top-n hit scores using two different approaches. The results for all scores with these methods indicated that the most successful metrics were binary_issue_related, issue_commented, binary_pr_related, and issue_opened. To verify our results, we compared our metrics with another metric generated from a very similar study and found that most of our metrics gave better scores that metric. In conclusion, the issue feature is more crucial for GitHub compared with other features. Moreover, commenting activity in projects can be equally as valuable as code contributions. The most of binary metrics that were generated, regardless of the number of activities, also showed remarkable results. In this context, we presented improvable and noteworthy developer metrics that can be used for a wide range of open-source software development challenges, such as user characterization, project recommendation, and code review assignment.","2021-02","2025-04-08 17:22:20","2025-04-08 17:22:20","","","","3","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open source; GitHub; pull request; commit; developer metric; issue; project recommendation system","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors (”problem solvers”) tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs (”problems”) tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between “core” and “peripheral” members identified exclusively on the basis of their individual level of contribution to the project.

Past work has focused on characterizing the main differences between OSS and traditional forms of software RE. In this effort we focus on differences in RE activity in OSS. RE is characterized as a socio-technical distributed cognitive (DCog) activity where multiple actors deploy artifacts to `compute' requirements. To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community. Finally the velocity of change in technological requirements influence the project's documentation practices of requirements with the level of design consistency desired in the end product influencing the decision-making channels used in the development endeavor.","2016","2025-04-08 17:22:20","2025-04-08 17:22:20","","4982-4991","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Pacific Res Inst Informat Syst & Management; Univ Hawaii Manoa, Shidler Coll Business, Dept IT Management; IBM; Provalis Res; Int Soc Serv Innovat Profess; Teradata; Univ Network; IEEE Comp Soc ISSN: 1060-3425 Type: Proceedings Paper","","/Users/mgone/Zotero/storage/8CCUQ5QT/Gopal et al. - 2016 - Attributes of Open Source Software Requirements - .pdf","","","","Bui, TX; Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Chemical processes are invariably described by non-linear equations such as chemical reaction kinetics, flow-pressure relationships and physical properties. Dynamic simulation of such systems involves the solution of sets of non-linear differential and algebraic equations. There is also uncertainty associated with the model equations themselves (model uncertainty), their parameters (parametric uncertainty) and the inputs into the model (input uncertainty). Tools that aid chemical engineers in the solution of these problems have been successfully commercialised and enjoy a measure of success, although the adoption of dynamic and stochastic simulation packages is lagging behind the steady-state flowsheeting tools. Commercial software solutions can be prohibitively expensive in addition to confining users to adhere to proprietary standards. The Free Software and Open Source movements have made inroads into providing non-proprietary alternatives to many commercial software packages, which has encouraged the adoption of open standards. This work presents a framework for the development of stochastic dynamic simulations of chemical processes using only free and open source software. The large problem of stochastic dynamic simulation has been broken down into stages: 1. Input modelling using Markov chain models trained on process data or seeded by hand in addition to stationary distribution models. This enables dynamic scenarios to be handled with the minimum of special case code generation. 2. Process modelling using an object-oriented approach in the Modelica language. Modelica has an actively developed open source implementation called OpenModelica and is an open standard modelling language. 3. Monte Carlo simulation using extensions to the OpenModelica compiler that ease parallel simulations 4. Postprocessing, including visualisation and statistical analysis. Statistics that are generated can be used for control evaluation purposes. The Tennessee-Eastman challenge process is used to illustrate its capabilities.","2011","2025-04-08 17:22:20","2025-04-08 17:22:20","","146-150","","","29","","","","Computer-Aided Chemical Engineering","","","","ELSEVIER SCIENCE BV","SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS","English","","","","","","","ISSN: 1570-7946 Type: Proceedings Paper","","","","Open Source; Segmentation; stochastic modelling","","Pistikopoulos, EN; Georgiadis, MC; Kokossis, AC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is debatable whether they should be used in open-source software (OSS) initiatives. There are studies examining the SRGMs' applicability in the OSS setting, but their scope is constrained by the models and projects they take into account, which could result in inconsistent findings. In this paper, the available SRGMs in the backdrop of OSS have been scrutinized and limitations have been identified. To address these limitations, a modification to the SRGMs using fuzzy neural networks (FNNs) has been proposed. In this paper, various SRGMs have been reviewed and sharp distinction among the same has been made, taking their respective failure intensity and mean value function under consideration. Through the failure intensity of software, it becomes a cakewalk to identify and predict the faults even before they actually arise and necessary and timely action may be initiated. After duly considering the review and contrast between the factors, a FNN model has been suggested for determination of software reliability differing with values of failure intensity and mean value function. First software failure data from a number of open-source software (OSS) projects have been gathered as part of the methodology used to modify traditional SRGMs. The proposed model gives out a high reliability rate and a low failure intensity. The most important factor is that it caters for the faults that are current and are being faced by the users on day to basis currently. It was found that the proposed model has a high success rate with the value of 82.6950937% which is considered as a successful result for software. The suggested FNN model may have a potential impact on the field of software reliability since FNN can handle the ambiguity and imprecision in the software failure data that are typical in open-source projects.","2023-07-04","2025-04-08 17:22:20","2025-04-08 17:22:20","","","","","","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article; Early Access","","","","Software reliability; Software reliability growth model; Failure intensity function; Fuzzy neural network (FNN); Logistic growth; Mean value function","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These volunteers, commonly referred to as OSS project community, serve as the foundation of the OSS project, fostering its creation and sustenance and providing long-term support. The quality and sustainability of the OSS project is reliant upon the development and structure of the self-governing community. When a business organization plans to acquire an OSS solution, it not only takes into consideration the factors such as reliability, security, and scalability but also attaches significant importance to the likelihood of the OSS project being maintained and supported in the future so that it can rely on it as a stable and secure technology solution. Modern cloud-based software hosting platforms, such as GitHub, offer a range of options for automatically and freely accessing the complete development history of millions of OSS projects. This easy availability of detailed development history has enabled researchers to analyze and draw quantitative and scientific inferences about the quality of an OSS project which generally involves assessing three aspects, namely, software product, development process, and project community. With focus on project community part, a Framework for Assessment and Ranking of OSS Community is being presented in the current research work, following a detailed examination of the largest source code hosting and project collaboration platform, GitHub. Technique for Order of Preference by Similarity to Ideal Solution from Multi-Criteria Decision-Making toolkit has been utilized for assessing the quality of the project community. The framework has been validated by applying it on nine OSS projects and comparing the results with the outcomes obtained through an existing OSS evaluation methodology. The comparative analysis demonstrated that the proposed framework aligns with the aforementioned evaluation methodology while offering an opportunity for in-depth analysis on the dynamics of volunteer communities, which is lacking in previous evaluation methods. These insights can prove valuable for both potential adopters and project maintainers, aiding them in making informed strategic decisions. Framework for Project Community Assessment and Ranking follows a phased approach where first phase involves OSS project identification, second phase defines assessment criteria, in third phase data is fetched, stored and metrics are computed; and the last phase involves final Quality Assessment and Ranking. The framework will aid both corporate entities and individual practitioners in identifying an open source project with a robust volunteer community capable of producing a product of exceptional quality.image","2024-07","2025-04-08 17:22:20","2025-04-08 17:22:20","","","","7","36","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","open source software; software quality; multi-criteria decision-making; project community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An increasing rate of urban growth and urban sprawl could induce changes in land use as well as land transformation. However, accurate and up-to-date information about LULC is required for providing better understanding and assessing the environmental consequences of such changes. In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80% and 80.40% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification. To summarize, ArcGIS and QGIS software are reliable to be used in the land cover classification.","2020","2025-04-08 17:22:20","2025-04-08 17:22:20","","","","","540","","","","IOP Conference Series-Earth and Environmental Science","","","","IOP PUBLISHING LTD","DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND","English","","","","","","","Backup Publisher: Inst Geospatial & Remote Sensing Malaysia; Univ Putra Malaysia; Sc & Technol Res Inst Def; Univ Teknologi Malaysia; Univ Utara Malaysia; Int Islam Univ Malaysia; Forest Res Inst Malaysia; GIS Innovat Sdn Bhd; GPS Lands M Sdn Bhd; IEEE Geoscience & Remote Sensing Soc, Malaysia Chapter ISSN: 1755-1307 Type: Proceedings Paper","","","","","","Omar, H; Shariff, ARM; Sathyamoorthy, D; Mat, RC; Tarmidi, Z; Ismail, MH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.","2021-12-02","2025-04-08 17:22:20","2025-04-08 17:22:20","","","","12","23","","","","","","","","","","English","","","","","","","Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC Type: Article","","","","sustainability; open-source software; cancer informatics; financial model; licensing model; product management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This may be achieved via education, training, consulting, hosting, and certification not only in terms of tools and platforms but also methodologies, studies, and best practices. Based on the experience of QualiPSo Competence Centres, we observe how such a Network is working as a mechanism for sharing success stories, failures, questions, recommendations, best practices, and any kind of information that could help the establishment of a solid international collaborative environment for supporting quality in FLOSS. New Competence Centres are invited to the QualiPSo Network after their proposals are evaluated by the QualiPSo Competence Centres Board to ensure that the prospective Competence Centre is compliant with the QualiPSo Network Agreement, sharing a common vision and ethics. Each Competence Centre acts in its geographical region to increase the awareness of FLOSS and to better prepare the IT workforce for developing and using FLOSS based solutions. As of 2009, the process for Competence Centre creation is sustainable and reusable; guidelines for establishing proposals and opening new Competence Centres have been created, and promotion of Qualipso Competence Centres is done world wide from India to USA thanks to key initiatives such as the Open World Forum and the FLOSS Competence Centre Summit.

According to this, the design of an integrated tourism management system is here discussed. The tourism management system is developed for the Insubria Region within the INSUBRIPARKS project, funded by the Interreg program of the European Union. The Insubria is a historical-geographical area stretches between Northern Italy and Southern Switzerland embedding a valuable historical and natural heritage. Nevertheless, the tourism potential of the region is not fully exploited due to a fragmented political context within the geographical area that extends across different local and national jurisdictions. The final goal of the project to increase tourism attractiveness of the Insubria Region through the provision of physical infrastructure, the development and promotion of new tourism experiences, and the deployment of a standardized Information Technology infrastructure to support cross-border land management and marketing operations. Central to this paper is the preliminary design of this infrastructure that will provide tools for supporting information generating and consuming among project partners and external stakeholders. The design phase leverages exclusively Free and Open Source Software. Alongside the preliminary architecture, both use cases and user requirements are discussed together with the expected benefits deriving from the co-creation of best tourism management practices by means of open and shared software platforms.","2019","2025-04-08 17:22:20","2025-04-08 17:22:20","","179-183","","","42-4","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences","","","","INTL SOC PHOTOGRAMMETRY & REMOTE SENSING-ISPRS","LEIBNIZ UNIV HANNOVER, INST PHOTOGRAMMETRY & GEOINFORMATION, NIENBURGER STR 1, HANNOVER, HANNOVER, GERMANY","English","","","","","","","Backup Publisher: ISPRS ISSN: 1682-1750 Issue: W14 Type: Proceedings Paper","","","","Cross-Border Cooperation; FOSS4G; Natural Heritage Management; Sustainable Tourism","","Brovelli, MA; Marin, AF","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Urban environments must therefore be at the heart of any global energy transition. Furthermore, land availability is a limiting factor for renewable deployment and rooftop PV thus offers a clear advantage. This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 % of the total electricity consumption of the city and where 50 % of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies. Additionally, this article provides valuable information, such as rooftop usability factors, and an overall reduction factor (CT), useful to extend RPVP assessment to larger areas using constant value methods.","2025-03-15","2025-04-08 17:22:21","2025-04-08 17:22:21","","","","","331","","","","","","","","","","English","","","","","","","Place: PO BOX 564, 1001 LAUSANNE, SWITZERLAND Publisher: ELSEVIER SCIENCE SA Type: Article","","","","Open-source software; Energy return on investment (EROI); Geographic information systems (GIS); Net energy analysis (NEA); Photovoltaic potential; Rooftop photovoltaics (RPV)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On this rationale, this study was carried out to explore the applicability of the concept of converging `Free and Open Source Software (FOSS)' to promote sustainable knowledge sharing amongst the agricultural communities in Sri Lanka. A multi-stage community consultative process with a set of designated officials (”Sponsors”) and a series of semi-structured questionnaire survey with a cross section of smallholder agriculture farmers (n=246), were carried out in the Batticaloa, Kurunegala and Puttalam districts to gather the baseline data. This was followed by a number of field experiments (”Campaigns”) with the farmers (n=340) from same geographical areas. The two FOSS, namely: (1) “FrontlineSMS” for `Text Messaging' and (2) “FreedomFone” for `Interactive Voice Responses', were applied to evaluate the effectiveness of knowledge sharing within the farming communities. It was found that FOSS intervention increases the `Text messaging' and `Voice Call' usage in day-to-day agricultural communication by 26 and 8 percent, respectively. The demographic factors like age and educational level of the farmers have a positive influence on the knowledge sharing process. And also the `Mobile Telephony' was the most extensive mode of communication within the communities. The outcome of analysis, as a whole, implies that, with a fitting mechanism in place, this approach can be promoted as a “drive for positive changes” in agriculture-based rural communities in developing countries like Sri Lanka, and those in South and East Asia with similar socioeconomic and cultural perspectives.","2017","2025-04-08 17:22:21","2025-04-08 17:22:21","","351-359","","2","111","","","","","","","","","","English","","","","","","","Place: VIA ANTONIO COCCHI 4, FLORENCE, 50131, ITALY Publisher: AGENZIA ITALIANA COOPERAZIONE SVILUPPO-ITALIAN DEV COOP AGENCY Type: Article","","","","FOSS; Information; Knowledge sharing; Agricultural community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

SU2 is one of these open -source tools. Unlike other open -source alternatives, SU2 is equipped with boundary condition types, solvers and methods that are especially developed for the analysis and design of turbomachinery. The aim of this work is to explore and investigate the capabilities of SU2 in the prediction of performance parameters of radial compressors. Two different single stage shrouded compressor geometries, one with a vaneless diffuser and the other with a vaned diffuser have been investigated with steady state CFD. The compressors were designed by MAN Energy Solutions Schweiz AG. Computational results with SU2 showed a satisfactory agreement with both the experimental data and reference CFD solutions obtained with Fidelity Flow, which is formerly known as Numeca Fine TURBO. Only at the relatively higher mass flow rates the difference between references and SU2 were higher compared to other operating points. After performance parameters were successfully calculated with SU2, the optimization tools that come with SU2 were also used. A 2D adjoint optimization study on the vane of the vaned diffuser was carried out. The study was carried out at a single operating point that is close to choke conditions. The loss generated by the large separated flow region at the suction side of the diffuser vane was reduced by 0.55 % in the optimized geometry using minimal modifications on the existing vane geometry to keep the performance of the compressor intact at other operating points. However, the resulting modification increased the total pressure loss by 0.86 % at one of the design operating points. This performance penalty could be due to the discontinuity in the vane geometry generated by the optimizer. Overall, the study shows that SU2 has the basic numerical schemes and models that are required for the analysis of radial turbomachinery flows and geometry optimization.","2023","2025-04-08 17:22:21","2025-04-08 17:22:21","","233-242","","2","43","","","","","","","","","","English","","","","","","","Place: TIBTD MAKINA MUHENDISLIGI BOLUMU ODTU, ANKARA, 06531, Turkiye Publisher: TURKISH SOC THERMAL SCIENCES TECHNOLOGY Type: Article","","","","Optimization; Open-source; Compressor; Computational Fluid Dynamics; SU2; Turbomachinery","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio [finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

In these studies, segmentation and quantification of myocardial infarct lesion are often performed with a commercial software or an in-house closed-source code development thus creating a barrier for reproducible research. This paper introduces CMRSegTools: an open-source application software designed for the segmentation and quantification of myocardial infarct lesion enabling full access to state-of-the-art segmentation methods and parameters, easy integration of new algorithms and standardised results sharing. This post-processing tool has been implemented as a plug-in for the OsiriX/Horos DICOM viewer leveraging its database management functionalities and user interaction features to provide a bespoke tool for the analysis of cardiac MR images on large clinical cohorts. CMRSegTools includes, among others, user-assisted segmentation of the left-ventricle, semi- and automatic lesion segmentation methods, advanced statistical analysis and visualisation based on the American Heart Association 17-segment model. New segmentation methods can be integrated into the plug-in by developing components based on image processing and visualisation libraries such as ITK and VTK in C++ programming language. CMRSegTools allows the creation of training and testing data sets (labeled features such as lesion, microvascular obstruction and remote ROI) for supervised Machine Learning methods, and enables the comparative assessment of lesion segmentation methods via a single and integrated platform.

The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was “Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang” held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes. Field work activity conducted and confirmed the changes that occurred in the study areas. Our study shows that all of the two districts exhibit successfulness of the plantation program. Ground truth survey confirmed that the successfulness of the plantation program is due to the participation of communities in the area of study. This study also shows that by using open source software and freely available satellite images, the fast, robust, and reliable data as an initial step to monitor both short-term and long-term plantation program can be collected effectively and inexpensively.","2017-08","2025-04-08 17:22:21","2025-04-08 17:22:21","","251-259","","3","9","","","","","","","","","","English","","","","","","","Place: IR SUTAMI 36 A, SURAKARTA, 57126, INDONESIA Publisher: UNIV SEBELAS MARET Type: Article","","","","Classification; remote sensing; Indramayu; Landsat TM/ETM+/OLI; mangroves; Subang","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are several factors that affect a developer's decision to join an OSS project, yet little research examined the influence of third-party assessments on a developer's intention to join a project. Drawing on signaling theory, this manuscript explores how third-party assessment can influence a developers' decision to join an OSS project. In order to test it, vignette survey study was conducted manipulating reputation, development experience, and a number of current OSS projects of existing developers in the OSS project. The findings suggest that all three signals have a positive influence on developer's decision to join the OSS project. This suggests that projects seeking to expand the number of contributing developers should consider offering information about its “star developers”.","2018","2025-04-08 17:22:21","2025-04-08 17:22:21","","","","","","","","","","","","","ASSOC INFORMATION SYSTEMS","P.O.

Students use OSS applications and systems in their courses on programming, operating systems, DBMS. web development to name but a few. Studying OSS projects from both a product and a process view also forms part of the software engineering curriculum at various universities. Many students have taken part in OSS projects as well as developers. At the University of Lincoln, under the Undergraduate Research Opportunities Scheme (UROS), undergraduate student researchers have the chance to work over the summer embedded within an existing research centre on a UROS project. Here two such projects within the Centre for Research in Open Source Software (CROSS) are described: Collaborative Development for the XO Laptop (CODEX) and Software Modularity in Open Source Software (SoMOSS). The CODEX project focused on creating resources to support students undertaking software application development for the XO laptop, and the SoMOSS project focused on architectural studies of OSS instant messaging software. Both projects achieved successful research outcomes; more importantly, both student researchers benefited directly from the encouragement and concrete assistance that they received through interaction with the wider OSS research community. Both projects are ongoing and present further research opportunities for students.","2009","2025-04-08 17:22:22","2025-04-08 17:22:22","","340-350","","","299","","","","International Federation for Information Processing","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","Backup Publisher: IFIP WG 2 13 ISSN: 1571-5736 Type: Proceedings Paper","","","","","","Boldyreff, C; Crowston, K; Lundell, B; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of biological sciences, information commons, such as public biobanks and free/libre open source software (FLOSS), are of paramount importance for both research and the bioeconomy. In a time of digitalization, however, information commons are vulnerable to violations, such as the free-rider problem, that render the commons unsustainable. Consequently, it has been argued that the enclosure of the informational common resources is the only means to effectively exploit them. Given the social and economic importance of the information commons, the new digital environment in biology and health requires governance innovation that will regulate the social embedding of the commons and their relationship to the free market, that is, a new political economy is needed. In this context, the need for a core common infrastructure, stretching from the physical to the logical and content layer of the information environment, that will guarantee the protection of the commons from both violations and enclosures, has been highlighted. Focusing on the interaction between two biological/bioinformatics commons, namely public biobanks and the FLOSS, we have set up an ecosystem relying on a blockchain technology. The proposed governance mechanism protects the information commons from the free-rider problem and guarantees their sustainability without hampering their operational framework. Our model demonstrates the interdependence and protection of the information commons not as an abstract theoretical exercise, but rather as a physical reality on the digital ontological matrix.","2020-05-01","2025-04-08 17:22:22","2025-04-08 17:22:22","","278-285","","5","24","","","","","","","","","","English","","","","","","","Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC Type: Article","","","","digitalization; political economy; blockchain; free; libre open source software; public biobanks; the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Key considerations when considering prognostic enrichment include: clinical trial sample size; the number of patients one must screen to enroll the trial; and total patient screening costs and total per-patient trial costs. The Biomarker Prognostic Enrichment Tool for Survival Outcomes (BioPETsurv) is a suite of methods for estimating these elements to evaluate a prognostic enrichment biomarker and/or plan a prognostically enriched clinical trial with a time-to-event primary endpoint. BioPETsurv allows investigators to analyze data on a candidate biomarker and potentially censored survival times. Alternatively, BioPETsurv can simulate data to match a particular clinical setting. BioPETsurv's data simulator enables investigators to explore the potential utility of a prognostic enrichment biomarker for their clinical setting. Results demonstrate that both modestly prognostic and strongly prognostic biomarkers can improve trial metrics such as reducing sample size or trial costs. In addition to the quantitative analysis provided by BioPETsurv, investigators should consider the generalizability of trial results and evaluate the ethics of trial eligibility criteria. BioPETsurv is freely available as a package for theRstatistical computing platform, and as a webtool at www.prognosticenrichment.com/surv.","2020-09-18","2025-04-08 17:22:22","2025-04-08 17:22:22","","","","9","15","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While 3DP has gained tremendous popularity, it remains a daunting and perceptibly time-consuming process for the inexperienced user, with most turning to commercially printed products. Commercial vendors are expensive. We propose that 3DP is feasible for the inexperienced user with the appropriate knowledge and tools.Methods: A 3DP protocol was created for model design and printing using open-source software and a low-cost desktop printer. It was betatested by 3 inexperienced users. The fidelity of the protocol was then tested in direct comparison to industry models made for 3 patients undergoing mandibular distraction osteogenesis, using standard cephalometric measurements.Results: All inexperienced testers were able to successfully create a 3D model using the easy-to-follow protocol without the use of any other resources. The models were created in a mean time of 170 minutes. All cephalometric measurements on the open-source printed models were equal to within 0.5 to 1.0 mm of the respective industry models.Conclusions: As the 3DP process is simplified and desktop printers and materials become more affordable, we anticipate that its implementation will become more commonplace.

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage. The empirical investigation in this paper shows that the switching points of stages have meaningful associations with the release dates.","2014","2025-04-08 17:22:22","2025-04-08 17:22:22","","207-212","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nowadays, it is becoming challenging to procure bone legally, resulting in medical students' inadequacy of bone. Plaster -of -Paris or resin bone models sold on the market are less detailed than real bones. Aims and objectives This study aims to create a three-dimensional (3D)-printed human bone model with free, open-source software and fused deposition modelling (FDM) 3D printers, compare its accuracy with the original bones and validate it with a textbook description. Methods Scapula and hip bone models were produced using open-source software 3D Slicer from computed tomography (CT) data from the “New Mexico Decedent Image Database”. After automated segmentation, bones were edited manually with tools in a 3D Slicer (https://www.slicer.org/) and Meshmixer software (Autodesk Inc., San Rafael, California, United States) and 3D bone models were printed using polylactic (PLA) filament. Results and discussions 3D digital models of both bones were successfully created with the maximum possible accuracy with an FDM 3D printer. A 3D digital replica of the scapula obtained after segmentation retained most anatomical features except for the glenoid cavity, as the head of the humerus obscured the glenoid cavity. The 3D digital skeleton of the hip bone retained all anatomical features except articulating surfaces, such as the acetabulum and auricular surface ilium, which were obscured by the head of the femur and sacrum. A few morphological features of both bones differed from the original dry bone, and a few finer details were unclear in the iliac fossa and ischium. After manual editing and post -processing, the final physical model obtained has all the features.

This paper seeks to broaden the research on virtual communities by applying the theory of competency rallying (TCR) in a longitudinal manner to examine the impact of task identification, task assignment, task execution and task management on user interest in open source software (OSS) projects defined by popularity and communication. The aim of this paper is: (I) re-conceptualizing the concept of user interest and broadening our understanding of user interest by incorporating users' post-usage behaviors, (2) examining the effect of various tasks involved in an OSS project's key processes of defect-fixing and feature-enhancement on user interest. The current study found that project popularity is positively influenced by task assignment, task execution and task management. Additionally, user communication was found to be positively impacted by task identification and task execution. The data collected from 1178 OSS projects in a longitudinal manner (at 3 time points over a period of 16 months) confirmed the expectations from TCR and also demonstrated that over time the effects that development of competencies and managing short term cooperative work have on project success might increase, while the impact of identifying market needs and marshalling competencies may not significantly change.

In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere.

Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.","2007-05","2025-04-08 17:22:22","2025-04-08 17:22:22","","211-235","","2","93","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","free and open source software; artifact; Bruno Latour; public sphere theory; socio-technical deliberation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work introduces Dareplane, a modular and broad technology-agnostic open source software platform for brain-computer interface (BCI) research with an application focus on adaptive deep brain stimulation (aDBS). One difficulty for investigating control approaches for aDBS resides with the complex setups required for aDBS experiments, a challenge Dareplane tries to address. Approach. The key features of the platform are presented and the composition of modules into a full experimental setup is discussed in the context of a Python-based orchestration module. The performance of a typical experimental setup on Dareplane for aDBS is evaluated in three benchtop experiments, covering (a) an easy-to-replicate setup using an Arduino microcontroller, (b) a setup with hardware of an implantable pulse generator, and (c) a setup using an established and CE certified external neurostimulator. The full technical feasibility of the platform in the aDBS context is demonstrated in a first closed-loop session with externalized leads on a patient with Parkinson's disease receiving DBS treatment and further in a non-invasive BCI speller application using code-modulated visual evoked potential (c-VEP). Main results. The platform is implemented and open-source accessible on https://github.com/bsdlab/Dareplane. Benchtop results show that performance of the platform is sufficient for current aDBS latencies, and the platform could successfully be used in the aDBS experiment. The timing-critical c-VEP speller could be successfully implemented on the platform achieving expected information transfer rates. Significance. The Dareplane platform supports aDBS setups, and more generally the research on neurotechnological systems such as BCIs. It provides a modular, technology-agnostic, and easy-to-implement software platform to make experimental setups more resilient and replicable.","2025-04-01","2025-04-08 17:22:23","2025-04-08 17:22:23","","","","2","22","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP Publishing Ltd Type: Article","","","","open source software; brain-computer interface; brain-machine interface; c-VEP; closed-loop; deep brain stimulation; electrophysiology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then, it has become practically essential for identifying bacteria in microbiological diagnostic laboratories. In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from. MSProfileR has been developed in the R environment and offers a user-friendly web interface using the R Shiny framework. It is available on Microsoft Windows as a web browser application by simple navigation using the link of the package on Github v.3.10.0. MSProfileR is therefore accessible to non-computer specialists and is freely available to the scientific community. We evaluated MSProfileR using two datasets including exclusively MS spectra from arthropods. In addition to coherent sample classification, outlier MS spectra were detected in each dataset confirming the value of MSProfileR.","2024-06","2025-04-08 17:22:23","2025-04-08 17:22:23","","","","2","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","Github; R package; arthropod vectors; MALDI-TOF MS; quality control; rstudio; Shiny interface","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In that community, companies always play auxiliary roles, and integrate the result of OSS into their business activities. However, in the Eclipse open source software community, the main role of OSS development activities is taken over by companies. The relationship between individuals and companies is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of a company. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify a structure of co-creation in an OSS ecosystem led by companies considering the Eclipse community as one particular case. It also constructs a co-creation process model to promote sustainable development for an OSS ecosystem following two axes 1) value sharing and value acquisition, and 2) quantitative development and qualitative development.

This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

Although multitude of studies have provided effective models for OSS sustainability, their practical implications have been lacking because most identified features are not amenable to direct tuning by developers (e.g., levels of communication, number of commits per project). In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed a comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs). The ReACTs are practical advice with specific steps, found in prior work to associate with tangible results. Starting from a set of sustainability-related features, this study contributes 105 ReACTs to the SE community by analyzing 186 published articles. Moreover, this study introduces a newly developed tool (ReACTive) designed to enhance the exploration of ReACTs through visualization across various facets of the OSS ecosystem. The ReACTs idea opens new avenues for connecting SE metrics to actionable research in SE in general.","2024","2025-04-08 17:22:23","2025-04-08 17:39:05","","457-461","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSOFT; Huawei; Technol Innovat Inst; Google; JetBrains; Uber Type: Proceedings Paper","","","","Open Source Software; Sustainability; Literature Review; Research Actionable","","D'Amorim, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ability of the variometric approach to detect short-term dynamic behaviors in real-time mode in applications such as Global Navigation Satellite Systems (GNSS)-seismology and structural health monitoring is demonstrated, the demand for open-source VA software is increasing. However, open-source software that is capable of VA processing in real-time mode based on single- and dual-frequency multi-GNSS observations is scarce. In view of this fact, we have developed an open-source VA processing software called PPPH-VA that can evaluate single- and dual-frequency multi-GNSS observations in real-time mode. PPPH-VA is developed in the MATLAB environment, and it can simultaneously process GPS, GLONASS, Galileo, BeiDou-2, and BeiDou-3 data with the VA technique in real-time mode, employing both single- and dual-frequency observations. We evaluated PPPH-VA using shake table experiments based on real data, and the results demonstrate that it provides high accuracy in terms of detection of dynamic displacements. Toolbox can successfully detect the dominant frequencies of short-term dynamic behaviors and is capable of determining the amplitude values corresponding to the peak frequency at the sub-mm level. Moreover, in the time domain, it can obtain dynamic behaviors with an accuracy of millimeters.","2024-01","2025-04-08 17:22:23","2025-04-08 17:22:23","","","","1","28","","","","","","","","","","English","","","","","","","Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG Type: Article","","","","Open-source software; Dynamic displacement; High-rate; Multi-GNSS; PPPH-VA; Real-time; Variometric approach","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most large and complex software packages partitioned across multiple portals and involve many users - each with their role in the software package; those users have different perspectives on the software package, defined by their knowledge, responsibilities, and commitments. Thus, a multi-perspective approach has been used in usability evaluation to overcome the challenge of inconsistency between users' perspectives; the inconsistency challenge would lead to an ill-advised decision on the selection of a suitable OSS. This study aimed to assist the public and private organizations in evaluating and selecting the most suitable OSS. The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.","2023-01","2025-04-08 17:22:23","2025-04-08 17:22:23","","187-277","","01","22","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","evaluation; selection; open-source software (OSS); benchmarking; BWM; decision matrix; Multi-criteria decision making (MCDM); VIKOR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project's capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of subtopics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance.

Since then countless libraries across the United States have used the program to create online tutorials in order to teach a variety of information literacy skills including how to search databases, how to evaluate websites, how to create better searches, and how to search for medical information. The Guide on the Side was created by a group of University of Arizona librarians in order to replicate the hands-on experience students received when they attended a library session on how to use a research database. Librarians aimed to give students the guided instruction they received in face-to-face sessions. Sophisticated research databases are often difficult for undergraduate students to use, and they need both background knowledge and repeated practice to use a database successfully. With the Guide on the Side, students are presented with authentic tasks and are able to conduct “live” searches as they are guided through the database. Through these activities, they learn how to locate the information they need quickly. Although a valuable and easy to use software program, instructors and librarians are often at a loss for how to create tutorials that are appealing to students and that are aligned with best practices for online instruction. This paper will focus on best practices when using the Guide on the Side. These best practices have been developed by the author and are based on current educational research focused on online instruction and on usability studies conducted using the Guide on the Side. This paper discusses the development of the Guide on the Side, how to download it, and how to implement these best practices in order to create learning experiences for students that are both engaging and effective.","2017","2025-04-08 17:22:23","2025-04-08 17:22:23","","395-400","","","","","","","INTED Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1079 Type: Proceedings Paper","","","","information literacy; guide on the side; library; online instruction; tutorials","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we here propose an information system that facilitates the use of BIM for geo-analysis purposes. BIM4GeoA is a concept for combining existing open source software and open specification for efficient data management and analysis of Building Information within its boarder context. The core components are the spatial database PostgreSQL/PostGIS, the building information server, the industrial foundation class (IFC), the Google Earth 3D viewer, and the existing 3D OGC standard (KML, CityGML). This paper presents the procedure used to enable the development of this new expert system as applied to the context of 3D Web GIS. A thorough analysis of the strength and weakness of these different components has been undertaken to employ it is strength and override its weakness. The system architecture is operationally used in developing different applications for the management of a university campus; a large potential is provided for operational tasks of facility management department, such as utilities infrastructure, as well as public community (student, staff) like routing application, searching for a person with defined criteria.","2010","2025-04-08 17:22:23","2025-04-08 17:22:23","","45-49","","","38-4","","","","International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences","","","","COPERNICUS GESELLSCHAFT MBH","BAHNHOFSALLE 1E, GOTTINGEN, 37081, GERMANY","English","","","","","","","Backup Publisher: Int Soc Photogrammetry & Remote Sensing ISSN: 2194-9034 Issue: W15 Type: Proceedings Paper","","","","Open Source; Information system; 3D GIS; BIM; CAD; Open Specification","","Kolbe, TH; Konig, G; Nagel, C","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. “simple”, intermediate” or “complex”, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.","2020-07-15","2025-04-08 17:22:24","2025-04-08 17:22:24","","","","","266","","","","","","","","","","English","","","","","","","Place: 24-28 OVAL RD, LONDON NW1 7DX, ENGLAND Publisher: ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD Type: Article","","","","Remote sensing; Cover estimation; Ecological monitoring; Guidos toolbox; Invasive alien species; Morphological spatial pattern analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.","2001-10","2025-04-08 17:22:24","2025-04-08 17:22:24","","277-304","","4","11","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","trust; control; McDonaldization; networked organization; rationalization; virtual organization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess “proof” of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and activities match those in their paid employment. Following a cohort of OSS programmers over a six-year period, we empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, our findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18% increase in wages. Moreover, we find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management. These findings suggest that rank within an OSS meritocracy is a credible and precise signal of participants' productive capacity and that participants' roles and activities in an OSS community have additional financial value when aligned with their paid employment.","2013-09","2025-04-08 17:22:24","2025-04-08 17:22:24","","520-538","","3","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software; signaling theory; job matching theory; labor economics; software industry","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V.

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.","2013-12","2025-04-08 17:22:24","2025-04-08 17:22:24","","361-370","","4","38","","","","","","","","","","English","","","","","","","Place: TWO COMMERCE SQ, 2001 MARKET ST, PHILADELPHIA, PA 19103 USA Publisher: LIPPINCOTT WILLIAMS & WILKINS Type: Article","","","","open source software; qualitative research; health information technology; hospital administration; vendors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.","2009-07-17","2025-04-08 17:22:24","2025-04-08 17:22:24","","","","","8","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, cognitively translating 2D images to surgical settings can be difficult and lead to sub-optimal resections. Lymph node dissection can be challenging due to the inability to locate small metastatic lesions, and their proximity to at-risk organ(s). 3D volume rendered (3D-VR) patient specific images can help to address these challenges. We created patient-specific 3D-VR images using freely available open-source programs. Methods: This study included patients part of the clinical trial NCT04857502. Patients received a PET/CT prior to radioguided surgery. 3D Slicer was used to segment anatomy of interest (organs and tumor lesion(s)). After segmentation, the data was exported as an .OBJ file with an accompanying .MTL file. Manipulation of the .MTL file to restore model properties to the .OBJ file, were completed and both files were uploaded into Autodesk Viewer. Surgeons then received an email link to access the finished 3D-VR model on their smartphone or laptop for peri-operative preparation and/or guidance. Results: The method was used in a series of 14 patients with prostate cancer undergoing pelvic lymph node dissection with PSMA-radioguided robotic surgery using pre-operative PSMA PET/CT images acquired on average 103 +/- 69 days prior to resection. The creation of the 3D-VR models was successfully conducted in all 14 cases. In all cases, the lesions identified on the pre-operative PET/CT imaging 3D-VR models were successfully removed during surgery. Conclusion: We created patient-specific anatomical 3D-VR models that the surgeons can use for pre-surgical planning and intraoperative tumor localization, by applying free, open-source software that could be used in any procedure requiring careful and strategical planning.","2025-04","2025-04-08 17:22:24","2025-04-08 17:22:24","","10-16","","","236","","","","","","","","","","English","","","","","","","Place: 525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA Publisher: ACADEMIC PRESS INC ELSEVIER SCIENCE Type: Article","","","","3D imaging; 3D volume rendered models; Anatomical models; Pelvic lymph node dissection; PET/CT; PSMA; Radioguided surgery; Surgical planning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this experience report, which is an invited extension of a recently published work [1], we first analyze both functional and non-functional JIT requirements from three successful open source software (OSS) projects, including Firefox, Lucene, and Mylyn, to explore the common activities that shaped those requirements. We identify a novel refinement and resolution process that all studied requirements followed from their inception to complete realization and subsequent release. Noticing some interesting phenomena more specific to non-functional requirements (NFRs), we conduct a second study examining 50 NFRs from the aforementioned three subject systems. This study reveals a slightly different process followed in the refinement and resolution of NFRs. It also provides further evidence that NFR refinement and resolution activities focus more on implementation refinement rather than requirement elaboration in the studied systems. Our research provides new insights into how OSS project teams create quality features from simple initial descriptions of JIT requirements, uncovers activities more particular to JIT requirements engineering (RE) for NFRs, and opens new avenues for further research in the emerging JIT RE field.","2019-06","2025-04-08 17:22:24","2025-04-08 17:22:24","","24-33","","","14","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Functional requirements; Just-in-time requirements; Non-functional requirements; Refinement; Resolution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-08 17:22:25","2025-04-08 17:37:16","","2366-2380","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSAC; Huawei; Natl Sci Fdn; Technol Innovat Inst; Twenty Second Century Dora Technol; Ant Res; IBM; TikTok; Abelian; Input Outut Type: Proceedings Paper","","","","patch backporting; patch semantics; patch type; Patch backporting; Patch Semantics; Patch type","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we assume that the number of fault-detections observed on the bug tracking system tends to infinity, and discuss a method of statistical process control (SPC) for OSS projects by applying the logarithmic Poisson execution time model as a software reliability growth model (SRGM) based on a nonhomogeneous Poisson process (NHPP). Then, we propose a control chart method based on the logarithmic Poisson execution time model for judging the statical stability state, and estimating the additional development time for attaining the objective software failure intensity, i.e., the target value of the instantaneous fault-detection rate per unit time. We also discuss an optimal software release problem for determining the optimum time when to stop OSS development and to transfer it to user operation. Further, numerical illustrations for SPC are shown by applying the actual fault-count data observed on the bug tracking system.","2016-10","2025-04-08 17:22:25","2025-04-08 17:22:25","","","","5","23","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","Open source software (OSS); additional development time; control chart; logarithmic Poisson execution time model; software reliability growth model (SRGM); statistical process control (SPC)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We have developed a new generic software package for the solution of inverse problems implementing the Ensemble Smoother with Multiple Data Assimilation (genES-MDA). It is an open-source, platform-independent Python-based program. Its aim is to facilitate the management and configuration of the ES-MDA through several programming tools that help in the preparation of the different steps of ES-MDA. genES-MDA has a flexible workflow that can be easily adapted for the implementation of different variants of the ensemble Kalman filter and for the solution of generic inverse problems. This paper presents a description of the package and some application examples. genES-MDA has been tested in three synthetic case studies: the solution of the reverse flow routing for the estimation of the inflow hydrograph to a river reach using observed water levels and a calibrated forward model of the river system, the identification of a hydraulic conductivity field using piezometric observations and a known forward flow model, and the estimation of the release history of a contaminant spill in an aquifer from measured concentration data and a known flow and transport model. The results of all these tests have demonstrated the flexibility of genES-MDA and its capabilities to efficiently solve different types of inverse problems.","2022-10","2025-04-08 17:22:25","2025-04-08 17:22:25","","","","","167","","","","","","","","","","English","","","","","","","Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND Publisher: PERGAMON-ELSEVIER SCIENCE LTD Type: Article","","","","Python; Covariance localization and inflation; Stochastic inverse modeling; Uncertainty characterization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We show this framework by calculating spatial indicators-for 25 diverse cities in 19 countries-of urban design and transport features that support health and sustainability. We link these indicators to cities' policy contexts, and identify populations living above and below critical thresholds for physical activity through walking.

In this work we focus our attention on what is perceived of a source code when investigating its structure. We do this considering that structure as a proxy for the conceptual architecture of the application. A metric is developed based on some current assumptions, and it is tested over a sample of Open Source projects. What is interesting to note, is that refactoring efforts are clearly visible when intended as reduction of complexity of source code. Our second observation is that, based on what an Open Source software currently does, i.e. its application domain, there's a threshold value that several projects tend to.","2004","2025-04-08 17:22:25","2025-04-08 17:37:44","","58-66","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc, TCSE; Nokia; TietoEnator; Tampere Univ Tech ol; Acad Finland; Reengineering Forum Type: Proceedings Paper","","/Users/mgone/Zotero/storage/FCAMGIYZ/Capiluppi et al. - 2004 - Evolution of understandability in OSS projects.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Model predictive control (MPC) has been shown to be a successful control strategy generally and as well as for managing urban drainage specifically. This research describes and demonstrates the implementation of MPC for urban drainage systems using open source software (Python and The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM5). The system was demonstrated using a simplified use case in which an actively-controlled outlet of a detention pond is simulated. The control of the pond's outlet influences the flood risk of a downstream node. For each step in the SWMM5 model, a series of policies for controlling the outlet are evaluated. The best policy is then selected using an evolutionary algorithm. The policies are evaluated against an objective function that penalizes primarily flooding and secondarily deviation of the detention pond level from a target level. Freely available Python libraries provide the key functionality for the MPC workflow: step-by-step running of the SWMM5 simulation, evolutionary algorithm implementation, and leveraging parallel computing. For perspective, the MPC results were compared to results from a rule-based approach and a scenario with no active control. The MPC approach produced a control policy that largely eliminated flooding (unlike the scenario with no active control) and maintained the detention pond's water level closer to a target level (unlike the rule-based approach).","2019","2025-04-08 17:22:25","2025-04-08 17:22:25","","988-992","","","","","","","Green Energy and Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","ISSN: 1865-3529 Type: Proceedings Paper","","","","Active stormwater control; Flood prevention; Low-relief coastal cities; Model predictive control","","Mannina, G","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.","2016","2025-04-08 17:22:25","2025-04-08 17:22:25","","37-44","","","","","","","Proceedings of the European Conference on Knowledge Management","","","","ACAD CONFERENCES LTD","CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND","English","","","","","","","ISSN: 2048-8963 Type: Proceedings Paper","","","","knowledge sharing; communities of practice; clusters; free software communities; sharing profiles","","Moffett, S; Galbraith, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11-01","2025-04-08 17:22:25","2025-04-08 17:38:57","","597-625","","4","42","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","; ; ","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Volunteers; Social Networks; Free software; Cooperation; article; Property; Computer Software; Capitalism; social change & economic development; Economic theory; Free and open-source software; Profitability; Profits; Values; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations; 0715:social change and economic development; Economic Sectors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computed tomography (CT) is commonly used to overcome projection errors in two-dimensional angular measurements of dog hindlimb alignment. Three-dimensional volume rendering (VR) techniques permit virtual positioning and variable projection, but the final CT-image that defines the projection plane for angular measurements remains two-dimensional.Objective We wanted to develop a true three-dimensional open-source technique to measure the alignments of the hind limbs of dogs in CT scanners.Methods We developed an open-source 3D Slicer plug-in, to perform angular measurements using vector calculations in three-dimensional space. In 113 CT-scans of canine pelvic limbs, femoral torsion, femoral varus, femorotibial rotation, tibial torsion, tibial varus and tibiotalar rotation angles were calculated and compared to an already validated technique using VoXim (R).Results Reference points were identified and measurements were possible in the 113 acquisitions. The greatest difference between the two techniques was 1.4 degrees at only one tibial torsion angle. Mean values for all Bland-Altman plots did not show significant differences and were less than 0.07 degrees for all comparisons.Discussion Based on these results we considered angular measurements of canine hind limb alignment in CT scans using the 3D Slicer extension program sufficiently accurate for clinical orthopedic and surgical purposes in veterinary medicine.Conclusion With our open-source 3D Slicer extension software, we provide a free accessible tool for veterinary orthopedic surgeons and thus we hope to improve angular measurements in CT-scans of canine hind limb deformities through true three-dimensionality.","2024-03-29","2025-04-08 17:22:25","2025-04-08 17:22:25","","","","3","19","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: Ten STL dental and maxillofacial models were obtained from various imaging technologies, including intraoral scanners, computer-aided design (CAD) software, and cone-beam computed tomography (CBCT), and saved as STL files. ChatGPT was used to generate Python scripts in Blender for mesh simplification and data compression, which were then saved as .py files. The models were regenerated from these scripts in Blender, and their accuracy was assessed using GOM Inspect software, comparing trueness and precision. Statistical analysis, including Kruskal-Wallis and Mann-Whitney tests, was conducted to evaluate differences in file sizes between the original, Python-generated, and regenerated STL files, with statistical analyses performed at a level of significance alpha=0.05. Results: The scripting-based technique was successfully utilized in ChatGPT to generate Python script code for accessing comprehensive data on STL models, utilizing Blender's scripting functionality. This approach enabled the generation, regeneration, and visualization of STL models, resulting in significantly smaller file sizes for both the Python script and regenerated STL files compared to the original STL files (p < 0.001). No significant differences in trueness were observed, with deviations ranging from 0.0 m to 6.8 mu m, and all regenerated STL models demonstrated perfect precision. Additionally, a proportional relationship was noted between the original STL file sizes and processing times. Conclusions: The scripting-based approach proved to be effective in coding, storing, and regenerating STL dental data with reduced file sizes and efficient processing times without compromising the accuracy. Clinical Significance: Various STL dental models of patients can be coded, stored, and regenerated to be used again within efficient processing time without affecting the accuracy.","2025-05","2025-04-08 17:22:26","2025-04-08 17:22:26","","","","","156","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Dentistry; Open-source software; 3d data management; accuracy; Blender scripting; Stl file optimization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace.

The framework we proposed is composed of three components, interventions design, democratization, and execution. We believe that this process will work for other FOSS communities too.

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.","2018-05","2025-04-08 17:22:26","2025-04-08 17:22:26","","","","5","10","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","QGIS; remote sensing; global warming; land surface temperature; Landsat-8; semi-automatic classification plugin; urban heat island; urbanization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computational intelligence (CI) in general and particle swarm optimization (PSO) algorithms in particular have been shown to accelerate finding optimal printing parameters. Unfortunately, the implementation of CI has been prohibitively complex for noncomputer scientists. To overcome these limitations, this article develops, tests, and validates PSO Experimenter, an easy-to-use open-source platform based around the PSO algorithm and applies it to optimizing recycled materials. Specifically, PSO Experimenter is used to find optimal printing parameters for a relatively unexplored potential distributed recycling and additive manufacturing (DRAM) material that is widely available: low-density polyethylene (LDPE). LDPE has been used to make filament, but in this study for the first time it was used in the open source fused particle fabrication/fused granular fabrication system. PSO Experimenter successfully identified functional printing parameters for this challenging-to-print waste plastic. The results indicate that PSO Experimenter can provide 97% reduction in research time for 3D printing parameter optimization.

What can we do to incentivize developers to write code? We started the study by introducing the population pyramid visualization to software development communities, called software population pyramids, and found a typical pattern in shapes. This pattern comes from the differences in attracting coding contributors and discussion contributors. To understand the causes of the differences, we then build game-theoretical models of the contribution situation. Based on these results, we again analyzed the projects empirically to support the outcome of the models, and found empirical evidence. The answers to the initial questions are clear. To incentivize developers to code, the projects should prepare documents, or the projects or third parties should hire developers, and these are what sustainable projects in GitHub did in reality. In addition, making innovations to reduce the writing costs can also have an impact in attracting coding contributors.","2015","2025-04-08 17:22:26","2025-04-08 17:34:40","","15-21","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE COMP SOC; TCSE; ACM; SIGSOFT Type: Proceedings Paper","","","","OSS; Game Theory; Population Pyramids","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways. This may be due primarily to the fact that open source ultimately produces greater value on both the use and production sides, implying an impact on welfare. This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market. To support this, a market concentration index, the HHI index, is tested over the case of web servers. As a result the study reveals that under the appropriate conditions, OSS call have a positive impact on welfare.","2008","2025-04-08 17:22:27","2025-04-08 17:22:27","","1-26","","","","","","","Social Issues Justice and Status","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Stroud, BH; Corbin, SE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose RecGFI, an effective practical approach for the recommendation of good first issues to newcomers, which can be used to relieve maintainers' burden and help newcomers onboard. RecGFI models an issue with features from multiple dimensions (content, background, and dynamics) and uses an XGBoost classifier to generate its probability of being a GFI. To evaluate RecGFI, we collect 53,510 resolved issues among 100 GitHub projects and carefully restore their historical states to build ground truth datasets. Our evaluation shows that RecGFI can achieve up to 0.853 AUC in the ground truth dataset and outperforms alternative models. Our interpretable analysis of the trained model further reveals interesting observations about GFI characteristics. Finally, we report latest issues (without GFI-signaling labels but recommended as GFI by our approach) to project maintainers among which 16 are confirmed as real GFIs and five have been resolved by a newcomer.","2022","2025-04-08 17:22:27","2025-04-08 17:55:34","","1830-1842","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; Assoc Comp Machinery, Special Interest Grp Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","open-source software; onboarding; good first issues","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key factor for the success of a free software project is its development dynamics, dependent on the attraction and retention of users and developers. The license plays an important role in this scenario, because by imposing restrictions on the use of the source code it attracts potential contributors in a different way. The degree of restriction of the license and an indicator of success of free software were related: the time between stages, that is, the time spent to evolve through the various stages of development.

To keep this foundation intact, the open source community needs to actively invest in sustainable approaches to bring in new contributors and nurture existing ones. We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a “rising contributor” badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.","2022","2025-04-08 17:22:27","2025-04-08 17:33:51","","36-40","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery Type: Proceedings Paper","","","","open source; maintainers; social good","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Harmonizing processes and analytical lenses for determining preparation for UX maturity are still challenging, and studies to create them are limited. The analysis is ad hoc and based on the actors ` will and experiences. This study proposes and validates analytical lenses.

The success of open source software is known to be attributable to a massive number of contributors engaging in the development process. However, an efficient open source software project is not guaranteed simply by active participation by many; a coordination mechanism is needed to seamlessly manage the multi-party collaboration. On this basis, this study aimed to examine the internal regulatory processes based on Git and GitHub, which serve as such a mechanism, and redefine the efficiency of open source software projects to fully reflect them. For this purpose, a two-stage data envelopment analysis was used to measure the project efficiency reflecting the internal processes. Moreover, this study considered the Kruskal-Wallis test and Tobit regression analysis to examine the effects of the participation by many on an open source software project based on the newly defined efficiency. Results show that a simple increase in contributors can be poisonous in terms of the efficiency of open source software projects.","2018-09","2025-04-08 17:22:28","2025-04-08 17:22:28","","","","9","10","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","GitHub; collaboration; Git; open source software projects; efficiency; data envelopment analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The concept of “trust” in social networking has been successfully applied to facilitate choice in similar situations. We propose a social network-based approach to quality assessment and evaluation of F/OSS applications. The proposed system utilises the community formed around F/OSS projects to produce meaningful recommendations based on specific user preferences. We suggest that such an approach would overcome some of the difficulties complicating user choice by making useful suggestions and can fit seamlessly within the structure of the majority of F/OSS projects. The main focus of this work is on the end users of free and open source software and not on the developers of the software.

It has been reported that less than 10% of Open Source Software (OSS) contributors in GitHub are women. Although related qualitative and quantitative studies point out the gender gap, the technical and social interaction of females within OSS still remain unexplored and largely misunderstood. As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions. Thus, we propose to answer the questions: where are females in OSS projects? How they evolve? and How they contribute to the sustainability of the OSS social capital?. We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity. We found that females are extremely underrepresented within OSS communities, but when they participate they are productive just as males, they evolve following relatively the same patterns than males and remain more involved in projects than males.","2019","2025-04-08 17:22:28","2025-04-08 17:22:28","","308-319","","","","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","Backup Publisher: IFIP WG 5 5 COVE Co Operat infrastructure Virtual Enterprises & Elect Business; Soc Collaborat Networks; Politecnico Torino; Nova Univ Lisbon; UNINOVA; Univ Amsterdam ISSN: 1868-4238 Type: Proceedings Paper","","","","Open Source Software; Social Network Analysis; Diversity; Gender; Socio-Technical interactions","","CamarinhaMatos, LM; Afsarmanesh, H; Antonelli, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To capture structural information of source files in call graph, we use node2vec algorithm to convert file entities within projects into knowledge mappings within low-dimensional space, based on which we further propose four features to capture the work status and social relationship of developers. We then design a recommender system using random forest method to recommend appropriate experts for the developers.

From large technology companies to startups, companies are participating in the OSS ecosystem by open-sourcing their technology, sponsoring projects through funding or paid developer time. However, our understanding of the OSS ecosystem is rooted in the “old world” model where individual contributors sustain OSS projects. In this work, we create a more comprehensive understanding of the hybrid OSS landscape by investigating what motivates companies to contribute and how they contribute to OSS. We conducted interviews with 20 participants who have different roles (e.g., CEO, OSPO Lead, Ecosystem Strategist) at 17 different companies of different sizes from large companies (e.g. Microsoft, RedHat, Google, Spotify) to startups. Data from semi-structured interviews reveal that company motivations can be categorized into four levels (Founders' Vision, Reputation, Business Advantage, and Reciprocity) and companies participate through different mechanisms (e.g., Developers' Time, Mentoring Time, Advocacy & Promotion Time), each of which tie to the different types of motivations. We hope our findings nudge more companies to participate in the OSS ecosystem, helping make it robust, diverse, and sustainable.","2023","2025-04-08 17:22:29","2025-04-08 17:56:11","","2617-2629","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; Melbourne Convent Bur; State Govt Victoria; CSIRO; Huawei; Monash Univ; Meta; Google; AWS; Monash Univ; Dragon Testing Technol; IBM; Univ Melbourne; RMIT Univ ISSN: 0270-5257 Type: Proceedings Paper","","/Users/mgone/Zotero/storage/D73KUWH6/Guizani et al. - 2023 - Rules of Engagement Why and How Companies Partici.pdf","","open source; motivations; OSS; Open Source; diversity; companies in open source","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These projects often provide onboarding guidelines in their `CONTRIBUTING' files (e.g., CONTRIBUTING.md on GitHub). These files explain, for example, how to find open tasks, implement solutions, and submit code for review. However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions' adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file. Our approach may help community builders identify missing information in the project ecosystem they maintain and newcomers can understand what to expect in CONTRIBUTING files.","2023","2025-04-08 17:22:29","2025-04-08 17:36:39","","16-28","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei Type: Proceedings Paper","","","","open source; software engineering; FLOSS; novices; onboarding","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We thus suggest that partner recommendation across different roles may benefit both the users and developers, i.e., once we are able to make successful recommendation for those in need, it may dramatically contribute to the productivity of developers and the enthusiasm of users, thus further boosting OSS projects' development. Motivated by this potential, we model the partner recommendation as link prediction task from email data via network embedding methods. In this article, we introduce time-series snapshot network (TSSN) that is a mixture network to model the interactions among users and developers. Based on the established TSSN, we perform temporal biased walk (TBW) to automatically capture both temporal and structural information of the email network, i.e., the behavioral similarity between individuals in the OSS email network. Experiments on ten Apache data sets demonstrate that the proposed TBW significantly outperforms a number of advanced random walk-based embedding methods, leading to the state-of-the-art recommendation performance.","2022-08","2025-04-08 17:22:29","2025-04-08 17:22:29","","1048-1059","","4","9","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","social network; Productivity; Task analysis; Sustainable development; Social networking (online); Data models; Synchronization; open-source software (OSS); Link prediction; network embedding; partner recommendation; random walk; Search problems; temporal network","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, research on the structural stability of the evolving developer collaboration network in OSS communities is relatively insufficient. In this paper, according to the software version sequence, we construct the corresponding developer collaboration network of the Angular OSS community and then analyse this network's structural stability during network evolution. The results show that the network always presents an economical modular small-world structure during its evolution. The maintenance of the structure is related to a cohesive core, which is composed of two types of nodes (i.e., hubs and connectors). The hubs organize noncore nodes to form modules, while connectors facilitate the formation of inter-module connections. The overall results highlight the important role of core developers in the sustainable development of OSS communities and may provide a reference for community initiators to implement protection strategies for core developers.","2022-07-08","2025-04-08 17:22:29","2025-04-08 17:22:29","","","","7","17","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","/Users/mgone/Zotero/storage/2IPIKWEM/Peng et al. - 2022 - Structural stability of the evolving developer col.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we report about our experience in using SCRUM for the development of an Open Source Software Java tool. With this work, we aim at answering the following research questions: 1) is it possible to switch successfully to the SCRUM methodology in an ongoing Open Source Software development process? 2) is it possible to apply SCRUM when the developers are geographically distributed? 3) does SCRUM help improve the quality of the product and the productivity of the process? We answer to these questions by identifying a set of measures and by comparing the data we collected before and after the introduction of SCRUM. The results seem to show that SCRUM can be introduced and used in an ongoing geographically distributed Open Source Software process and that it helps control the development process better.","2010","2025-04-08 17:22:29","2025-04-08 17:22:29","","147-159","","","48","","","","Lecture Notes in Business Information Processing","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","ISSN: 1865-1348 Type: Proceedings Paper","","","","OSS; agile methods; Open-source Software; process improvement evaluation; SCRUM","","Sillitti, A; Martin, A; Wang, XF; Whitworth, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such capstone projects may be student-designed, instructor-designed, designed in conjunction with outside companies, or integrated with ongoing free and open source (FOSS) projects. The literature shows that the FOSS approach has attracted a great deal of interest, in particular when implemented with projects that have humanitarian goals (HFOSS). In this article, we describe five unique models from five distinct types of institutions for incorporating sustained FOSS or HFOSS (alternatively H/FOSS) project work into capstone experiences or courses. The goal is to provide instructors wishing to integrate open source experiences into their curriculum with additional perspectives and resources to help in adapting this approach to the specific needs and goals of their institution and students. All of the models presented are based on sustained engagement with H/FOSS projects that last at least one semester and often more. Each model is described in terms of its characteristics and how it fits the needs of the institution using the model. Assessment of each model is also presented. We then discuss the themes that are common across the models, such as project selection, team formation, mentoring, and student assessment. We examine the choices made by each model, as well as the challenges faced. We end with a discussion how the models have leveraged institutional initiatives and collaborations with outside organizations to address some of the challenges associated with these projects.","2018-07","2025-04-08 17:22:30","2025-04-08 17:30:40","","","","2, SI","18","","","","","","","","","","English","","","","","","","Place: 2 PENN PLAZA, STE 701, NEW YORK, NY 10121-0701 USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","FOSS; Open source; capstones; HFOSS; humanitarian; projects","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Owing to the unrestricted access to source code, version control information, and bug tracking database, a comprehensive study on the Development Process associated with an OSS project is feasible. In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.","2025-03","2025-04-08 17:22:30","2025-04-08 17:22:30","","","","1","33","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Open source software; GitHub; Software quality; Operations research; Development process; Multi-criteria decision analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The ADC can record a temporal signal produced by chromatography and flow-injection analysis. It has two voltage measurement ranges: +/- 2.048 V and +/- 1.024 V, respectively, with 14-bit resolution and a four samples s(-1) sampling rate. The voltage resolution is 0.25 mV and 0.125 mV per one ADC reading for +/- 2.048 V and +/- 1.024 V, respectively. Its dimensions were 100x70x30 mm, and mass was 110 g. We have evaluated its performance, including the linearity and the difference between the two devices. For +/- 1.024 V range, the calibration curve for one ADC and another was D = 7954V 5 and D = 7946V + 30, respectively, where D is an ADC reading, and V is an input voltage. For another range, it was D = 3972V - 3 and D = 3968V + 15, respectively. Their slopes and intercept agreed with each other, and had good linearity, R-2 > 0.9999.

The copyright regime is so restrictive that it turns a normal learning process into a series of potential copyright violations. The Free Software Movement (FSM) represents a substantial community effort to counter this trend. It seeks to supersede the copyright regime by offering the `Copyleft' licensing mode, which facilitates the formation of a cooperative, resource- sharing community. The FSM has been so successful that it has challenged the utilitarian values presumed in copyright law, has fuelled widespread reassessment of copyright law, and has influenced many who engage in various creative activities. Claiming to bear similar values, Creative Commons (CC) provides licensing models for people to waive some rights granted to them. However, CC differs from the FSM in significant ways. Most notably, the flexible CC licensing model weakens the firm philosophical and political ground which binds FSM advocates together. Hence, although CC's rapid growth seems to signal its success, it is questionable whether such success is as enduring as the FSM's, or if it is leading to a different result. While CC champions the author's freedom to decide how to use his or her bundle of property rights granted by copyright law, the FSM advocates the freedom to build and live in an alternative, vital and self- sustaining community. The existence of such an alternative model not only allows these particular participants to be independent from the proprietary world, but also may empower the rest of society to imagine different kinds of relationships between human beings and their creative activities.","2006-12","2025-04-08 17:22:30","2025-04-08 17:22:30","","337-347","","4, SI","4","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We model the individual's chances to become a valuable contributor through her capacity, willingness, and the opportunity to contribute at the time of joining. Using issue tracking data of Mozilla and Gnome, we find that the probability for a new joiner to become a Long Term Contributor (LTC) is associated with her willingness and environment. Specifically, during their first month, future LTCs tend to be more active and show more community-oriented attitude than other joiners. Joiners who start by commenting on instead of reporting an issue or ones who succeed to get at least one reported issue to be fixed, more than double their odds of becoming an LTC. The micro-climate with a productive and clustered peer group increases the odds. On the contrary, the macro-climate with high project popularity and the micro-climate with low attention from peers reduce the odds.

Current literature explains the contributors' lifecycle, starting with the motivations that drive people to contribute and barriers to joining OSS projects, covering developers' evolution until they become core members. However, the stages when developers leave the projects are still weakly explored and are not well-defined in existing developers' lifecycle models. In this position paper, we enrich the knowledge about the leaving stage by identifying sleeping and dead states, representing temporary and permanent brakes that developers take from contributing. We conducted a preliminary set of semi-structured interviews with active developers. We analyzed the answers by focusing on defining and understanding the reasons for the transitions to/from sleeping and dead states. This paper raises new questions that may guide further discussions and research, which may ultimately benefit OSS communities.","2019","2025-04-08 17:22:30","2025-04-08 18:14:26","","9-16","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc Type: Proceedings Paper","","","","communities; open source; developers turnover; project abandonment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

ESE (endoscopic submucosal excavation) is widely used for the treatment of digestive diseases. The dental floss traction (DFT) method has been successfully used to facilitate ESE to resect mucosal lesions such as early gastric cancer. DFT has not been used in ESE to remove submucosal masses. This study aimed to examine the efficacy of DFT-assisted ESE (DFT- ESE) for the removal of submucous masses. Methods. From March 2017 to May 2017, a total of 12 patients with gastric submucosal masses at the First Affiliated Hospital of Nanchang University, Jiangxi, China, were enrolled. The tumor characteristics, en bloc resection rates, complications, and outcomes on follow-up were evaluated for all patients. Results. The 12 submucosal tumors were completely removed by DFT- ESE. Nine were gastrointestinal stromal tumors. Two were Schwannoma, located in the greater curvature of the gastric corpus. One was gastric ectopic pancreas. All the resected tumors were removed completely with intact tumor capsules. There was no more bleeding or perforation after the endoscopic closure of the perforation or the wound after the DFT-ESE, and no recurrences were identified at the time of follow-up. Conclusions. The DFT method efficiently and safely facilitated the ESE procedure during the resection of gastric submucosal tumors.

Our vision, BugExchange, is a system that curates tasks from OSS projects to help train newcomers. While evaluating and executing these tasks, newcomers can gain an understanding about the project, its technology, and concepts. There are many challenges in designing such a system. For example, identifying the information needs of newcomers, creating task recommendations that match newcomers' skills and career goals, and providing mentoring and networking support.

In spite of the success produced with existing mining techniques, emerging questions about FLOSS data require alternative and more appropriate ways to explore and analyse such data. In this paper, we explore a different perspective called process mining. Process mining has been proved to be successful in terms of tracing and reconstructing process models from data logs (event logs). The chief objective of our analysis is threefold.

Proper empirical methods that can shed light into FLOSS development are desirable. In this paper, we propose an empirical method to validate a software development model for FLOSS, the Adapted Staged Model for FLOSS. We mined some selected metrics from Apache Ivy and study their evolution using S-shaped curves. Our results indicate that S-shaped curves can model software evolution well for Ivy.

Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system's sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries. Specifically, we leveraged a weighted combination of semantics, lexical, and shallow features in conjunction with the Random Forest ensemble learning method. Finally, we discuss the practical applicability of our classifier for mapping and visualizing quality-related concerns into the codebase with an example from the Derby project. To summarize, this work represents an effort and an early awareness to improve the underlying management of issue tracking systems and stakeholder requirements in open-source communities.","2021","2025-04-08 17:22:31","2025-04-08 17:22:31","","12-23","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process.

The objective of this research is to empirically examine the Brooks' Law in a Free Software context. The principle is separated out into its two primary premises: the first is based on a developer's ability to become productive when joining a new team; the second premise relates to the quality of coordination as the team grows. Three large projects are studied for this purpose: KDE, Plone and Evince. Based on empirical evidence, the paper provides two main contributions: based on the first premise of Brooks' Law, it claims that coordination costs increase only in a very specific phase for Free Software projects. After that, these costs become quasi-constant. Secondly, it shows that a ramp up period exists in Free Software projects, and this period marks the divide between projects that are successful at engaging new contributors from others that only benefit from occasional new contributors.","2009","2025-04-08 17:22:31","2025-04-08 17:22:31","","319-328","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Learning communities can still learn strategies of communication, organization and socialization from these communities, as well as the value of motivation and the importance of freedom and circulation of knowledge in order to build up efficient communities. We can also gain the understanding that the success of these communities depends on the fact that they are educational communities, therefore education studies can convey values, models and a culture of sharing to other sectors as well, such as the one taken into consideration: Free Software Communities.

Although industrial applications traditionally rely on PLC-based hardware and, in any case, proprietary software, i.e. operating systems and development tools, in recent years dramatic improvements in hardware computer power and free software quality made realistic the employment of architectures based on PC-compatible hardware and GNU/Linux software, more common in the research community. The advantages of a free infrastructure, that can become the terrain of fruitful cooperation between research institutions and companies, can be exploited mainly in fields, in which the added value is in the application, i.e. in mechanical and algorithmic solutions, and where the point of view is that of aware users of an infrastructure, rather than of R&D competitors. This is the case of the project presented in the following, representing a success story in which the discussion between a research group and a small enterprise led to the identification of the requirements and the joined development of a common software infrastructure. When the project started in 2004, both partners, i.e. the Autonomous robotic systems and control group of CNR-ISSIA and Green Project Srl, had to substitute the obsolete platforms of their marine robots and marking machines for casting products in steelworks with a stable software and hardware infrastructure able of transparently integrating technological improvements while remaining compatible with the past (backward compatibility). On the basis of considerations, discussed below, about system reliability, development and maintenance costs (including human resources), foreseen compatibility and general technical soundness, the choice was to verify the possibility of using standard GNU/Linux for embedded real-time applications. The result is the main technical contribution of this chapter, i.e. the practical demonstration of the possibility of using standard GNU/Linux for implementing embedded real-time control systems working up to a sampling frequency of at most 2 Khz. Furthermore, four years later, the developed system is still demonstrating its capabilities transparently integrating technological improvements and increasing more and more its performance thanks to the new real-time properties of the Linux kernel. A first operative release of the platform was completed in 2005 and integrated with the CNR-ISSIA Charlie unmanned surface vehicle (USV) for robotics research. A second application was the porting to the platform of the software of the control system of Hammer, a steelwork industrial machine used for marking continuous casting products, developed by Greenproject s.r.l. At the moment, the platform is supporting the development of the ALANIS (Aluminium Autonomous Navigator for Intelligent Sampling) USV1 for surface and underwater coastal monitoring. Moreover, the integration with generic field buses and image acquisition systems is being carried out. After an introduction reporting a summary of related research in the field and a discussion of the platform requirements, the key points of the followed methodology for making GNU/Linux real-time will be presented. Finally, two applications, a research one and an industrial one, pointing out the basic real-time structures that the platform is required to implement, will be described.","2010","2025-04-08 17:22:31","2025-04-08 17:29:55","","201-216","","","","","","","Computer Science Technology and Applications","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Komarov, F; Bestuzhev, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is a clonal B-cell disorder characterized by the proliferation of malignant plasma cells in the bone marrow, the presence of monoclonal serum immunoglobulin, and osteolytic lesions. An increasing amount of evidence shows that the interactions of MM cells and the bone microenvironment play a significant role, suggesting that these interactions may be good targets for therapy. The osteopontin-derived collagen-binding motif-bearing peptide NIPEP-OSS stimulates biomineralization and enhances bone remodeling dynamics. Due to its unique targeted osteogenic activity with a broad safety margin, we evaluated the potential of NIPEP-OSS for anti-myeloma activity using MM bone disease (MMBD) animal models. In a 5TGM1-engrafted NSG model, the survival rates of the control and treated groups were significantly different (p = 0.0014), with median survival times of 45 and 57 days, respectively. The bioluminescence analyses showed that myeloma slowly developed in the treated mice compared to the control mice in both models. NIPEP-OSS enhanced bone formation by increasing biomineralization in the bone. We also tested NIPEP-OSS in a well-established 5TGM1-engrafted C57BL/KaLwRij model. Similar to the previous model, the median survival times of the control and treated groups were significantly different (p = 0.0057), with 46 and 63 days, respectively. In comparison with the control, an increase in p1NP was found in the treated mice.

The difference between free software and open source ideology may influence founders, resulting in different types of companies being created. Specifically, the relationship between free/libre software ideology and social entrepreneurships is investigated. This paper presents seven case studies of businesses, five of which were founded by people who identify with the free/libre software movement. The result is a theory that small businesses founded by free/libre software advocates have three characteristics of social entrepreneurships. First, social benefit is prioritized over wealth creation.

During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS. These results suggest that an inter-family succession of Betaproteobacteria occurred in response to colonization by mosses, followed by plants.","2019-09-25","2025-04-08 17:22:32","2025-04-08 17:22:32","","268-277","","3","34","","","","","","","","","","English","","","","","","","Place: C/O DR.

Travel times allow to estimate the potential for interaction between people and places, and is therefore a vital measure for understanding the functioning, sustainability, and equity of cities. Here, we provide an open travel time matrix dataset that describes travel times between the centroids of all cells in a grid (N = 13,132) covering the metropolitan area of Helsinki, Finland. The travel times recorded in the dataset follow a door-to-door approach that provides comparable travel times for walking, cycling, public transport and car journeys, including all legs of each trip by each mode, such as the walk to a bus stop, or the search for a parking spot. We used the r5py Python package, that we developed specifically for this computation. The data are sensitive to diurnal variations and to variations between people (e.g. slow and fast walking speed). We validated the data against the Google Directions API and present use cases from a planning practice. The five key principles that guided the data set design and production - comparability, simplicity, reproducibility, transferability, and sensitivity to temporal and interpersonal variations - ensure that urban and transport planners, business and researchers alike can use the data in a wide range of applications.","2024-08-09","2025-04-08 17:22:32","2025-04-08 17:22:32","","","","1","11","","","","","","","","","","English","","","","","","","Place: HEIDELBERGER PLATZ 3, BERLIN, 14197, GERMANY Publisher: NATURE PORTFOLIO Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Meanwhile, software companies have successfully launched programs like Google Summer of Code (GSoC) and FindBugs “fixit” to contribute to open-source projects. Inspired by the success of these programs, we propose GitHub-OSS Fixit, a team-based course project where students are taught to contribute to open-source Java projects by fixing bugs reported in GitHub. We described our course outline to teach students SE concepts by encouraging the usages of several automated program analysis tools. We also included the carefully designed instructions that we gave to students for participating in GitHub-OSS Fixit. As all lectures and labs are conducted online, we think that our course design could help in guiding future online SE courses. Overall, our survey results show that students think that GitHub-OSS Fixit could help them to improve many skills and apply the knowledge taught in class. In total, 154 students have submitted 214 pull requests to 24 different Java projects, in which 93 of them have been merged, and 46 have been closed by developers.","2021","2025-04-08 17:22:32","2025-04-08 17:22:32","","1-10","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT Type: Proceedings Paper","","","","software engineering; Open-source software; program repair","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, our objective was to advance the practicality of drug-coated floss as an intra gum pocket drug delivery system. The initial design of this delivery system has been previously reported by us. Here, we advance the concept further through in vitro and in vivo evaluation. A floss piece was dip coated in the middle section with model molecules leaving free ends for holding. Porcine gum tissues were used ex vivo and in vivo to evaluate the coated floss, including effect of coating thickness on delivery efficiency, ability to deliver more than one type of molecule (one hydrophilic and one hydrophobic), mechanical properties using a scratch test, and finally retention of delivered material in vivo in the porcine model. After reaching a certain coating thickness, the delivery efficiency of the coated floss decreased, indicating the presence of an optimal coating thickness. Hydrophobic and hydrophilic molecules were successfully coated and delivered with high efficiency into gum pockets. The scratch test indicated that the coatings were resilient. Lastly, the in vivo analysis showed that the drug coating was delivered into the porcine gum pocket with about 65% efficiency, and the coatings could maintain extended residency within the gum pocket despite the native adverse environment of the oral cavity. Overall, this data shows that drug-coated floss can act as a drug delivery vehicle and has potential to provide a minimally invasive and practical method for the delivery of drugs into the gum pockets.","2022-06-29","2025-04-08 17:22:32","2025-04-08 17:22:32","","28663-28670","","25","14","","","","","","","","","","English","","","","","","","Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC Type: Article","","","","floss; coated; drug; gingivitis; gum; mouth; oral cavity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We have researched on Commercial Off the Shelf (COTS) devices (such mobile phones and tablets) to implement adhoc networking using open source software (OSS) such as Serval Mesh, MANET Manager, WiFi Tether applications. We have also modified the TrevE-Mod WiFi Tether application to work successfully with MANET Manager and Linux/ Windows based Personal Computers (PCs) in an adhoc network. The results achieved by performance evaluation tools and testing of VoIP applications have proved it to be satisfactory. We have also satisfactorily implemented, configured and tested point to point Virtual Private Network (VPN) between MANET nodes using OSS (VPN Server, OpenVPN for Android, OpenVPN Connect).

To determine the ideal time to apply an implant after augmentation with Bio-Oss Collagen and to observe if there are differences in the age of the patients and the sex, the aim of this randomized controlled clinical trial was to compare the post-extraction changes in angiogenic and osteogenic aspects during spontaneous bone regeneration with those during socket preservation using Bio-Oss Collagen. Sixty-six patients were included in this study. After 8-12 weeks, bone biopsies were embedded in paraffin and histological and immune-histological investigated. Using qRT-PCR bone (Alpl, Bglap, Runx2) and angiogenic markers (VEGF, caveolin-1) were identified. The histomorphometric analysis of all examined samples showed no differences between treated and untreated sockets, but a tissue compression. After classification in bone regeneration stages, more samples with woven bone were present in treated sockets than in controls. The Alpl expression correlates with increase in mature bone tissue. In treated sockets a significant decrease in CD34 and caveolin-1 protein expression was found. Additionally, a significant increase of Runx2 and VEGF mRNA was detected in patients younger than 50 years. Thus, all specimens showed ossification in different stages after eight weeks of healing. The treated group gives an earlier stage of ossification than controls, but produces densified tissue with greater volume fraction. It can be assumed that successful implant placement in Bio-Oss Collagen augmented extraction sockets is possible after eight weeks of bone healing. (C) 2021 Elsevier B.V.

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.","2014","2025-04-08 17:22:33","2025-04-08 17:22:33","","401-412","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery Special Interest Grp Software Engn; CVIC SE; NSF; Microsoft Res; Huawei; Neusoft; Siemens; Yonyou; Hong Kong Univ Sci & Technol; Google; Radica; Samsung Res Amer; IBM Res; TCL; CCC Type: Proceedings Paper","","","","sequence analysis; layered network; Markov entropy; structural complexity; Time-series","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of minimization reduces differences that might arise by chance between the study arms in the distribution of patient characteristics such as gender, ethnicity and age. However, unlike randomization, minimization requires real time assessment of each new participant with respect to the preceding distribution of relevant participant characteristics within the different arms of the study. For multi-site studies, this necessitates centralized computational analysis that is shared between all study locations. Unfortunately, there is no suitable freely available open source or free software that can be used for this purpose. OxMaR was developed to enable researchers in any location to use minimization for patient allocation and to access the minimization algorithm using any device that can connect to the internet such as a desktop computer, tablet or mobile phone. The software is complete in itself and requires no special packages or libraries to be installed. It is simple to set up and run over the internet using online facilities which are very low cost or even free to the user. Importantly, it provides real time information on allocation to the study lead or administrator and generates real time distributed backups with each allocation. OxMaR can readily be modified and customised and can also be used for standard randomization. It has been extensively tested and has been used successfully in a low budget multi-centre study. Hitherto, the logistical difficulties involved in minimization have precluded its use in many small studies and this software should allow more widespread use of minimization which should lead to studies with better matched control and experimental arms. OxMaR should be particularly valuable in low resource settings.","2014-10-29","2025-04-08 17:22:33","2025-04-08 17:22:33","","","","10","9","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whether a project participant is initiated as a developer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e. g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving developer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e. OSS developers patch submission activities. We use these sets to predict whether a project participant will become a developer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a developer. Further, we find that this is true to the extent that other predictors, e. g. patch submission info, need not be included in the models. In addition, we show that future developers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10% of the three month data's predictions. Finally, we find that it is easier to become a developer earlier in the projects lifecycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2013","2025-04-08 17:22:33","2025-04-08 17:56:27","","340-349","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Software Improvement Grp; Lab Qual Software ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play a crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process. In detail, we analyze what review feedbacks encourage a contributor to continue with OSS project. Using a Qt project dataset, we build a prediction model to identify a LTC. We find that not only contributor's activities, but also a reviewer feedbacks, useful in identifying LTCs.","2018","2025-04-08 17:22:33","2025-04-08 17:22:33","","109-113","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Int Assoc & Comp & Informat Sci; IEEE Comp Soc Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation. We demonstrate how OSS and systematic conservation planning can be taken to the wider community to produce on-the-fly outputs. Our novel approach has the potential to build partnerships with community groups and give the community a sense of ownership in the decision-making process. It is more likely that conflicts will be minimised and negotiation hastened for a better MPA zoning outcome for all.","2005","2025-04-08 17:22:33","2025-04-08 17:22:33","","1525-1531","","","","","","","","","","","UNIV WESTERN AUSTRALIA","NEDLANDS, WA, AUSTRALIA","English","","","","","","","Type: Proceedings Paper","","","","GIS; Conservation Planning; Decision Support; Marine Protected Areas; Public Participation","","Zerger, A; Argent, RM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails. These emails contain decisions for 466 Python Enhancement Proposals (PEPs) that document the language's evolution.

In their article, the authors make a strong case that “reset thinking” geared towards a more “sustainable” redesign of the global economy promotes extensive state interventionism and cronyism capitalism, and therefore reject the idea of a need for “a funda-mental rethink of existing management theory”. Whereas I do agree with the authors on most points, I am less convinced that “existing management theory” will suffice to address the problem of “reset thinking”. In this article, I demonstrate that the economy-bias of existing theories is a gateway for “reset thinking” geared towards an allegedly necessary re-/socialisation of management and organisation. A research agenda on cronyism must therefore be complemented by one on privilege and hierarchy not only as undesirable side-effects of cronyism, but also as desired outcomes of advocacy for specific minorities or missions. As self-identifications with group interests or calls for missions have become popular in management theory, I conclude that this new appetite for privilege might undermine not only the higher ideals of many management theorists, but also the foundations of modern society.","2023-09","2025-04-08 17:22:33","2025-04-08 17:22:33","","","","3","39","","","","","","","","","","English","","","","","","","Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Management theory; Conservatism; Cronyism; Restorism; Stratification; The Great Reset","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Deep learning frameworks have been proposed to facilitate the development of such software systems, among which, PYTORCH and TENSORFLOW stand out as notable examples. Considerable attention focuses on exploring software engineering practices and addressing diverse technical aspects in developing and deploying deep learning frameworks and software systems. Despite these efforts, little is known about the open source software communities involved in the development of deep learning frameworks. In this article, we perform a comparative investigation into the open source software communities of the two representative deep learning frameworks, PYTORCH and TENSORFLOW. To facilitate the investigation, we compile a dataset of 2,792 and 3,288 code commit authors, along with 9,826 and 19,750 participants engaged in issue events on GITHUB, from the two communities, respectively. With the dataset, we first characterize the structures of the two communities by employing four operationalizations to classify contributors into various roles and inspect the contributions made by common contributors across the two communities. We then conduct a longitudinal analysis to characterize the evolution of the two communities across various releases, in terms of the numbers of contributors with various roles and role transitions among contributors. Finally, we explore the causal effects between community characteristics and the popularity of the two frameworks. We find that the TENSORFLOW community harbors a larger base of contributors, encompassing a higher proportion of core developers and a more extensive cohort of active users compared to the PYTORCH community. In terms of the technical background of the developers, 64.4% and 56.1% developers in the PYTORCH and TENSORFLOW communities are employed by the leading companies of the corresponding open source software projects, Meta and Google, respectively; 25.9% and 21.9% core developers in the PYTORCH and TENSORFLOW communities possess Ph.D. degrees, while 77.2% and 77.7% contribute to other machine learning or deep learning open source projects, respectively. Developers contributing to both communities demonstrate spatial and temporal similarities to some extent in their pull requests across the respective projects. The evolution of contributors with various roles exhibits a consistent upward trend over time in the PYTORCH community. Conversely, a noticeable turning point in the growth of contributors characterizes the evolution of the TENSORFLOW community. Both communities show a statistically significant decreasing trend in the inflow rates of core developers. Furthermore, we observe statistically significant causal effects between the expansion of communities and retention of core developers and the popularity of deep learning frameworks. Based on our findings, we discuss implications, provide recommendations for sustaining open source software communities of deep learning frameworks, and outline directions for future research.","2025-03","2025-04-08 17:22:33","2025-04-08 18:13:44","","","","3","34","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","/Users/mgone/Zotero/storage/RC3JA7V8/Chen et al. - 2025 - Understanding the OSS Communities of Deep Learning.pdf","","GitHub; community evolution; Deep learning; developer classification","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study investigates the impact of co-membership taking into account the alternative mechanism of watching under the setting of OSS development at GitHub. It finds that both co-membership and watching contribute positively to OSS success, and thus shows the co-existence of both experiential learning and vicarious learning for OSS development.

For this system, the soft-output (SO) detector was recently proposed where a soft-metric (e.g., a log-likelihood ratio (LLR)) is computed from a hard-decision channel output by introducing a novel distance measure in the binary Hamming space. This makes it possible to be naturally incorporated into the state-of-the-art channel codes (e.g., low-density parity-check code or polar code). In this paper, we further improve the performance of the SO detector by exploiting a priori information (e.g., the previously decoded messages), which is called the one-bit successive-cancellation soft-output (OSS) detector. The key idea of the proposed OSS detector is that each user k's message is decoded sequentially via the associated channel decoder k in ascending order and a refined search-space is constructed using the previously decoded messages (i.e., the enhanced LLRs are generated). We then present a multiple OSS detector by taking into account a more practical scenario where the BS is equipped with multiple channel decoders. In addition, we propose an efficient way to determine a good decoding order by introducing a novel set-distance measure. Finally, simulation results demonstrate that the proposed OSS detector can significantly improve the existing SO detector for the coded MU-MIMO systems with one-bit ADCs.","2019","2025-04-08 17:22:34","2025-04-08 17:22:34","","27172-27182","","","7","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","Massive MIMO; multiuser MIMO detection; one-bit analog-to-digital converter (ADC); soft-output decoding.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to assist designers, many effective tools have been developed to support collaborative engineering, whose implementation is perceived as complex. Nowadays, industrial scenarios encourage companies to adopt PLM solutions, even if, sometimes, they can't understand the benefits. On the other hand, many free solutions with comparable functionalities are developed, which have been increasingly successful. In this article, we test different associations of software to make a comparison between free software and market solutions. In this experiment, 24 students in a Master's Degree course aimed to design mechanical products by using software to assist collaborative distributed design, using two different configurations. This experiment allowed us to compare design functionalities between free and commercial solutions, in order to determine ways to improve efficiency in a collaborative distributed design situation. Finally, the feedback generated in this experiment allowed us to adapt training practices in engineering education.","2012","2025-04-08 17:22:34","2025-04-08 17:22:34","","547-558","","","388","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: Int Federat Informat Proc Working Grp 5 1; PCO Innovat; Dassault Syst; Audros; Strategy Consulting & Innovat Prod Engn Inc; GPA; Lab Ingn Produits Procedes & Syst; CRIAQ ISSN: 1868-4238 Type: Proceedings Paper","","","","communication; free software; Engineering education; PLM","","Rivest, L; Bouras, A; Louhichi, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.","2016-05","2025-04-08 17:22:34","2025-04-08 17:51:45","","","","2","25","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","Measurement; natural experiment; Human Factors; commercial involvement; contributor inflow; contributor retention; extent and intensity of involvement; Hybrid project","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to mitigate the impact of natural hazards on European economies and societies, improved risk assessment, and management needs to be pursued. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models have become an important part of flood risk management (FRM). In this context, free and open-source (FOSS) geospatial models provide better and more complete information to stakeholders regarding their compliance with the Flood Directive (2007/60/EC) for effective and collaborative FRM. A geospatial model is an essential tool to address the European challenge for comprehensive and sustainable FRM because it allows for the use of integrated social and economic quantitative risk outcomes in a spatio-temporal domain. Moreover, a FOSS model can support governance processes using an interactive, transparent and collaborative approach, providing a meaningful experience that both promotes learning and generates knowledge through a process of guided discovery regarding flood risk management. This article aims to organize the available knowledge and characteristics of the methods available to give operational recommendations and principles that can support authorities, local entities, and the stakeholders involved in decision-making with regard to flood risk management in their compliance with the Floods Directive (2007/60/EC).","2015-12","2025-04-08 17:22:34","2025-04-08 17:22:34","","2704-2727","","4","4","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source; GIS; flood risk management; flood risk model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various quantities of fiber were employed to obtain nonwoven mats with a fiber content ranging from 5 to 35 kg/m3. Thermal conductivity and thermal diffusivity were measured across diverse relative humidity levels and temperatures. Simultaneously, milkweed floss samples were exposed to identical environmental conditions to assess the moisture regain and specific heat capacities of the fiber. The specific heat capacity of milkweed and thermal conductivity of the nonwovens exhibited a linear increase with temperature. The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content. The thermal insulation properties of the nonwovens remained partially stable below 30% relative humidity but substantially deteriorated at higher levels. The nonwovens exhibited optimal thermal insulation properties at a fiber content between 20 and 25 kg/m3. The results of this study highlighted several technical advantages of employing milkweed floss as a sustainable and lightweight solution for thermal insulation.","2024-01","2025-04-08 17:22:34","2025-04-08 17:22:34","","","","1","8","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","milkweed floss; nonwoven mat; R-value; seed fibers; specific heat capacity; thermal conductivity; thermal resistance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Core contributors and peripheral contributors work together to create a successful project, each playing a different role. One-Time Contributors (OTCs), who are on the very fringe of the peripheral developers, are largely unstudied despite offering unique insights into the development process. In a prior survey, we identified OTCs and discovered their motivations and barriers. Aims: The objective of this study is to corroborate the survey results and provide a better understand of OTCs. We compare OTCs to other peripheral and core contributors to determine whether they are distinct. Method: We mined data from the same code-review repository used to identify survey respondents in our previous study. After identifying each contributor as core, periphery, or OTC, we compared them in terms of patch size, time interval from submission to decision, the nature of their conversations, and patch acceptance rates. Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate. The peripheral developers fall in between the OTCs and the core contributors. Conclusion: OTCs do, in fact, face the barriers identified in our prior survey. They represent a distinct group of contributors compared to core and peripheral developers.","2017","2025-04-08 17:22:34","2025-04-08 17:22:34","","1-10","","","","","","","International Symposium on Empirical Software Engineering and Measurement","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: ACM; IEEE; IEEE Comp Soc; IBM ISSN: 1938-6451 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key success factor is to respond to customers' desires to choose the billing scheme that suits their needs, to subscribe to all services as a service package, and to pay for them via a single bill regardless of service type, service location, service providers and network operators. Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task. This paper presents key OSS functions and an information model that tackle this complexity. Challenges are described and requirements are defined. Related efforts are highlighted, and the context surrounding this work is laid out in detail.

It is believed that the seed flosses of common milkweed, Asclepias Syriraca, may be a promising reinforcing fiber given its uncommon hollow microstructure that is associated with both high specific properties and outstanding insulating capacities. This study presents an overview of the properties of milkweed floss and its potential use in reinforced-polymer composites. Milkweed flosses from Quebec were analyzed to determine their overall dimensions, density, porosity, coefficient of acoustic absorption, thermal conductivity, thermal resistance, and elastic modulus. In parallel, a portion of milkweed fibers was treated with acetone to modify their surface, and the properties of the treated fibers were measured and compared against the characteristics of the original fibers. Infrared spectroscopy was employed to assess differences between the chemical groups on the surface of treated and native fibers. The treatment with acetone removed fatty acids, waxes, and free sugars from the fibers' surface. The acetone treatment did not affect the fibers' microstructure nor their acoustic absorption capacity. The acetone-treated fibers showed greater thermal resistance and a higher thermal conductivity than native milkweed floss. The elastic modulus of milkweed decreased by nearly 49% after the acetone treatment.","2023-04-24","2025-04-08 17:22:34","2025-04-08 17:22:34","","","","1","20","","","","","","","","","","English","","","","","","","Place: 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA Publisher: TAYLOR & FRANCIS INC Type: Article","","","","fiber microstructure; mechanical properties; Natural hollow fibers; reinforcing fiber; thermal properties; thermo-acoustic insulation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94% of the surveyed core developers agreed with our state model of inactivity; 71% and 79% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26%, with a similar to 54% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.","2022-05","2025-04-08 17:22:35","2025-04-08 17:22:35","","","","3","27","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Retention; Disengagement; Abandonment; Open-source communities; Repository mining; Turnover","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The recent growth in demand for professional software engineers has led to increased contributions to, and usage of, OSS. However, there is limited understanding of the factors affecting how developers, and how new or student developers in particular, decide which OSS projects to contribute to, a process critical to OSS sustainability, access, adoption, and growth. To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (p < 0.0001, effect size = 0.84), student motivation (p < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (p < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner. Our findings may help improve the experience for new developers participating in OSS4SG and the quality of their contributions. We also hope our work helps educators, project leaders, and contributors to build a mutually-beneficial framework for the future growth of OSS4SG.","2023","2025-04-08 17:22:35","2025-04-08 17:29:39","","3-15","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei Type: Proceedings Paper","","","","Open Source Software; CS Education; Social Good","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whether a project participant is initiated as a committer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e.g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving committer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different Apache Software Foundation OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e., OSS developers' patch submission activities. We use these sets to predict whether a project participant will become a committer, and to characterize their socialization patterns around the time of becoming committer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a committer. Further, we find that this is true to the extent that other predictors, e.g., patch submission info, need not be included in the models. In addition, we show that future committers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10 % of the three month data's predictions. Interestingly, we find that on average, for each project, one's level of socialization ramps up before the time of becoming a committer. After obtaining committer status, their social behavior is more individualized, falling into few distinct modes of behavior. In a significant number of projects, immediately after the initiation there is a notable social cooling-off period. Finally, we find that it is easier to become a committer earlier in the projects life cycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2015-10","2025-04-08 17:22:35","2025-04-08 17:22:35","","1318-1353","","5","20","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Open source software; Logistic regression; Developer initiation; Email social networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While code reviews are a common measure to catch bugs during development, they lack scalability, are error-prone, and time-consuming [2,38,41]. Thus, static analysis tools like Semgrep emerged to provide programmatic feedback on code. But static analyses often show low precision, which can jeopardize utility. In this case study, we investigate precision rates for Semgrep OSS for common web weaknesses from the OWASP Top 10 [35]. We explore method and tool limitations in weakness detection, OWASP classes, and Semgrep's public PHP rule set. We apply the latter to 300 open source applications, invest 34 h in manual sample validation, and derive precision rates for each OWASP class. Our validation shows that the rules correctly detected weaknesses for seven OWASP classes with 86% precision, demonstrating the tool's utility. Yet, we estimate that most findings are not exploitable (81%). Thus, there is still considerable assessment overhead for users.

Our results show that successful FLOSS teams demonstrate a truly global distribution of members, who perform different types of work so as to achieve consistent round-the-clock development, without any apparent ill effects on team productivity and the quality of the resulting outcomes. Cooperation between team members is abundant, especially at more complex work items, and does not seem to be affected by distance; only mentoring relationships appear in some cases to be easier to cultivate between individuals living closer together.

It will be shown how a Volume Conductor Model (VCM) is constructed and examined using Python-controlled algorithms for generation, discretization and adaptive mesh refinement of the computational domain, as well as for incorporation of heterogeneous and anisotropic properties of the tissue and allocation of neuron models. The utilization of the platform is facilitated by a collection of predefined input setups and quick visualization routines. The accuracy of a VCM, created and optimized by the platform, was estimated by comparison with a commercial software. The results demonstrate no significant deviation between the models in the electric potential distribution. A qualitative estimation of different physics for the VCM shows an agreement with previous computational studies. The proposed computational platform is suitable for an accurate estimation of electric fields during DBS in scientific modeling studies. In future, we intend to acquire SDA and EMA approval. Successful incorporation of open-source software, controlled by in-house developed algorithms, provides a highly automated solution. The platform allows for optimization and uncertainty quantification (UQ) studies, while employment of the open-source software facilitates accessibility and reproducibility of simulations.","2020-07","2025-04-08 17:22:35","2025-04-08 17:22:35","","","","7","16","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, previous work shows that OSS newcomers often face several barriers to contribute, which lead them to lose motivation and even give up on contributing. A well-known way to help newcomers overcome initial contribution barriers is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in OSS projects. Studying mentors' perspectives on the barriers that newcomers face play a vital role in improving onboarding processes; yet, OSS mentors face their own barriers, which hinder the effectiveness of the strategy. Since little is known about the barriers mentors face, in this paper, we investigate the barriers that affect mentors and their newcomer mentees. We interviewed mentors from OSS projects and qualitatively analyzed their answers. We found 44 barriers: 19 that affect mentors; and 34 that affect newcomers (9 affect both newcomers and mentors). Interestingly, most of the barriers we identified (66%) have a social nature. Additionally, we identified 10 strategies that mentors indicated to potentially alleviate some of the barriers. Since gender-related challenges emerged in our analysis, we conducted nine follow-up structured interviews to further explore this perspective. The contributions of this paper include: identifying the barriers mentors face; bringing the unique perspective of mentors on barriers faced by newcomers; unveiling strategies that can be used by mentors to support newcomers; and investigating gender-specific challenges in OSS mentorship. Mentors, newcomers, online communities, and educators can leverage this knowledge to foster new contributors to OSS projects.","2018-12","2025-04-08 17:22:35","2025-04-08 17:22:35","","679-714","","3-6, SI","27","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article; Proceedings Paper","","","","Onboarding; Open source software; Challenges; Coach; Difficulties; Joining process; Mentor; Newbie; Newcomer; Novice; Obstacles; Tutor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most OTCs primarily made contributions to fix bugs that impeded their work and did not plan on becoming long term contributors.

Using social capital theory in a mixed methods case study, we compare entrepreneur and non-entrepreneur behaviors to investigate how entrepreneurs build social capital within an OSS community. This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation). Given the liabilities of newness and smallness as well as other challenges faced by entrepreneurs, applying an open innovation strategy in OSS communities could be one approach where entrepreneurs, by developing and freely revealing their intellectual property to the community, share their way to success via OSS-infused entrepreneurial business ventures.","2019-03","2025-04-08 17:22:35","2025-04-08 17:22:35","","23-40","","1","29","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Social capital; Entrepreneurship; Mixed methods case study; OSS Online communities; Virtual worlds","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As a first implementation, it is assumed that the forward models are perfect and that the radar data are sampled at the analysis grid points. A general purpose nonhydrostatic compressible model is used with the inclusion of complex multiclass ice microphysics. New aspects of this study compared to previous work include the demonstration of the ability of the EnKF method to retrieve multiple microphysical species associated with a multiclass ice microphysics scheme, and to accurately retrieve the wind and thermodynamic variables. Also new are the inclusion of reflectivity observations and the determination of the relative role of the radial velocity and reflectivity data as well as their spatial coverage in recovering the full-flow and cloud fields. In general, the system is able to reestablish the model storm extremely well after a number of assimilation cycles, and best results are obtained when both radial velocity and reflectivity data, including reflectivity information outside of the precipitation regions, are used. Significant positive impact of the reflectivity assimilation is found even though the observation operator involved is nonlinear. The results also show that a compressible model that contains acoustic modes, hence the associated error growth, performs at least as well as an anelastic model used in previous EnKF studies at the cloud scale. Flow-dependent and dynamically consistent background error covariances estimated from the forecast ensemble play a critical role in successful assimilation and retrieval. When the assimilation cycles start from random initial perturbations, better results are obtained when the updating of the fields that are not directly related to radar reflectivity is withheld during the first few cycles. In fact, during the first few cycles, the updating of the variables indirectly related to reflectivity hurts the analysis. This is so because the estimated background covariances are unreliable at this stage of the data assimilation process, which is related to the way the forecast ensemble is initialized. Forecasts of supercell storms starting from the best-assimilated initial conditions are shown to remain very good for at least 2 It.","2005-07","2025-04-08 17:22:35","2025-04-08 17:22:35","","1789-1807","","7","133","","","","","","","","","","English","","","","","","","Place: 45 BEACON ST, BOSTON, MA 02108-3693 USA Publisher: AMER METEOROLOGICAL SOC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, low retention of sEVs affects their therapeutic effects. Clinically used natural substitute inorganic bovine bone mineral (Bio-Oss) bone powder lacks high compactibility and efficient osteo-inductivity that limit its clinical application in repairing large bone defects. In this study, a poly ethylene glycol/hyaluronic acid (PEG/HA) hydrogel was used to stabilize Bio-Oss and incorporate rat bone marrow stem cell-derived sEVs (rBMSCs-sEVs) to engineer a PEG/HA-Bio-Oss (PEG/HA-Bio) composite scaffold. Encapsulation and sustained release of sEVs in hydrogel scaffold can enhance the retention of sEVs in targeted area, achieving long-lasting repair effect. Meanwhile, synergistic administration of sEVs and Bio-Oss in cranial defect can improve therapeutic effects. The PEG/HA-Bio composite scaffold showed good mechanical properties and biocompatibility, supporting the growth of rBMSCs. Furthermore, sEVs enhanced in vitro cell proliferation and osteogenic differentiation of rBMSCs. Implantation of sEVs/PEG/HA-Bio in rat cranial defect model promoted in vivo bone regeneration, suggesting the great potential of sEVs/PEG/HA-Bio composite scaffold for bone repair and regeneration.

It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS.

The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better.

It was noteworthy that the regeneration of alveolar bone was rapidly promoted to be shortened from the ordinary 3 months to 2 weeks. The nanoparticles designed by us according to the oral environment could protect microRNA from various enzymes and electrolytes attack, leading to a steady, continuous, and efficient delivery of gene.

Therefore, the use of biomaterials/scaffolds for maxillofacial bone regrowth has been attracting great interest from many surgical specialties and experts. Many approaches have been devised in order to create an optimal bone scaffold capable of achieving desirable degrees of bone integration and osteogenesis. Osteogenesis represents a complex physiological process involving multiple cooperating systems. A tight relationship between the immune and skeletal systems has lately been established using the concept of “osteoimmunology,” since various molecules, particularly those regulating immunological and inflammatory processes, are shared. Inflammatory mediators are now being implicated in bone remodeling, according to new scientific data. In this study, a profiler PCR array was employed to evaluate the expression of cytokines and chemokines in human adipose derived-mesenchymal stem cells (hASCs) cultured on porous hydroxylapatite (HA)/Collagen derived Bio-Oss((R))/Avitene scaffolds, up to day 21. In hASCs grown on the Bio-Oss((R))/Avitene biomaterial, 12 differentially expressed genes (DEGs) were found to be up-regulated, together with 12 DEG down-regulated. Chemokine CCL2, which affects bone metabolism, tested down-regulated. Interestingly, the Bio-Oss((R))/Avitene induced the down-regulation of pro-inflammatory inter-leukin IL-6. In conclusion, our investigation carried out on the Bio-Oss((R))/Avitene scaffold indicates that it could be successfully employed in maxillofacial surgery. Indeed, this composite material has the advantage of being customized on the basis of the individual patients favoring a novel personalized medicine approach.","2022-06-27","2025-04-08 17:22:36","2025-04-08 17:22:36","","","","","10","","","","","","","","","","English","","","","","","","Place: AVENUE DU TRIBUNAL FEDERAL 34, LAUSANNE, CH-1015, SWITZERLAND Publisher: FRONTIERS MEDIA SA Type: Article","","","","biomaterial; chemokine; cytokine; immunomodulation; osteogenic differentiation; stem cells","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The aim of this study was to assess the adhesion and migration of dental stem cells on human pulp ceiling cavities filled with these endodontic materials in an experimental model, which mimics the clinical conditions of regenerative endodontics. Cavities were formed, by a homemade mold, on untouched third molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities' surface and their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three materials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential morphology. Moreover, variations were observed when comparing cells numbers on cavity's filling versus the surrounding dentine disc. The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss. This was confirmed in the migration assay where a statistically significant lower number of cells migrated towards Bio-Oss as compared to MTA and dentin chips. This study highlights that MTA and dentin chips have a greater potential compared to Bio-Oss regarding the attraction of dental stem cells and are good candidates for bioengineered pulp regeneration.","2015","2025-04-08 17:22:36","2025-04-08 17:22:36","","","","","2015","","","","","","","","","","English","","","","","","","Place: ADAM HOUSE, 3RD FLR, 1 FITZROY SQ, LONDON, W1T 5HF, ENGLAND Publisher: HINDAWI LTD Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS and PEG were administered in 2 doses on the day before colonoscopy. Primary endpoint included proportion of patients with successful overall preparation (4-point scale). Secondary endpoints included overall and segmental bowel cleansing (Boston Bowel Preparation Scale; BBPS), completed colonoscopies, duration of examination, time to cecal intubation, proportion of nasogastric tubes (NGTs), adverse events (AEs) and acceptability.Results: Successful cleansing was achieved in 71.4% and 79.0% of patients receiving OSS and PEG, respectively [adjusted difference -7.61 (95% confidence interval, CI, -18.45 to 3.24); P = 0.0907].

In order to effectively promote the growth of online secondhand markets, this paper designs and validates a scale to assess customer perception of the service quality of secondhand products purchased via online platforms. Complementarily, the paper assesses how each of the different dimensions that configure the scale contributes to explaining the fulfillment of customers' expectations. The scale is defined by 23 items and is arranged in 5 dimensions from the literature on online commerce as well as on the sharing economy. A sample of 200 questionnaires is used for exploratory factor analysis. A second sample of 507 users is used for confirmatory factor analysis. The quality perceived by online customers of secondhand products depends on the quality of the interactions that they have with the website, with the vendor, and with the product. The dimension that contributes the most to customer fulfillment of expectations is product quality. Findings identify the items that contribute the most to quality perception and fulfillment of expectations, facilitating the development of more effective strategies for platform owners and vendors who want to attract and retain customers of secondhand products. Complementarily, these findings are useful to businesses and governments that want to promote a more sustainable economy by reducing consumption of new products and promoting reutilization of existing ones.","2020-11","2025-04-08 17:22:36","2025-04-08 17:22:36","","","","21","12","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","online; quality; fulfillment of expectations; secondhand","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: Sixty-eight patients who had difficulty in cannulation into the papilla located at the lower, left, or right side of the periampullary diverticulum upon endoscopic retrograde cholangiopancreatography (ERCP) were recruited at Taizhou Hospital from July 2016 to June 2020. A random number table was used to divide the patients into an intervention (with titanium clip-dental floss traction) group and a control group (n=34 in each group). Patients in both groups underwent ERCP. The cannulation time, cannulation success rate, incidence of postprocedural complications after ERCP, hospitalization time, and hospitalization expenses in the 2 groups were compared. Result: The cannulation time was 15.3 +/- 4.1 minutes in the intervention group, which was less than that in the control group (25.7 +/- 6.5 min). The cannulation success rate was 77 +/- 12.1% in the intervention group, which was higher than that in the control group (43 +/- 16.7%). Postprocedural complications occurred in 2 patients in the intervention group and 6 patients in the control group, with no significant differences.

From August to November 2014, a total of 95 patients with 104 gastric epithelial neoplasms underwent DFC-ESD (DFC group). Historical controls treated by conventional ESD (control group) were individually matched to cases at a 1:1 ratio by lesion location, ulcer findings, resected specimen size, and the proficiency of the operator (trainee/expert). The outcomes of the procedure in the two groups were then compared. The mean +/- A SD procedure time was 43 +/- A 24 min in the DFC group and 52 +/- A 30 min in the control group (P < 0.01). Fewer lesions in the DFC group needed > 80 min compared with the control group (3-vs-16 cases, P = 0.01). There were no significant differences in adverse events between the groups. Perforation and delayed bleeding occurred in one and four lesions, respectively, in the DFC group, and three and nine in the control group. En bloc resection was achieved in all cases.

Considering that traditional salinity reconstruction methods often suffer from various factors such as additional constraints, priori physical assumptions and large of specific regression coefficients, a generative adversarial networks (GANs) based deep learning (DL) framework is proposed to directly construct a near real-time, high-resolution daily three-dimensional ocean subsurface salinity (3D OSS) dataset from a data driven perspective in this study. Four models with different structural combinations are designed in the China's marginal seas. Experimental results demonstrate that the models can successfully reconstruct the high-precision and high-resolution 3D OSS on a daily scale in 12 depth levels (from 2 m to 200 m). The asymmetric inception3DGAN model with all enhanced structures has the highest accuracy, the average root-mean-squared error (RMSE) is 0.135psu, the average coefficient of determination (R2) is 0.5641 and the percent bias is 0.436%. Comparing with model without enhanced structures, the average RMSE is decreased by 22.41% when adding all the enhancement structures. Besides, temporal and spatial error analysis are also conducted to evaluate the models' performance from different aspects. Finally, the model results are used to analyze common ocean elements, such as water mass properties, dynamic fields and geostrophic velocity fields, demonstrating that the 3D OSS dataset construction approach proposed in this study not only provides some new insights into ocean observations, but also has high application values.","2023-08","2025-04-08 17:22:36","2025-04-08 17:22:36","","","","","184","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Deep learning; Data-driven; Generative adversarial networks; Ocean subsurface salinity; T-S mapping","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Increasingly complex simulations are used to assess similarities and differences between the two models' components. The simulations presented here are forced by ocean currents from a Finite Volume Community Ocean Model (FVCOM) implementation that has excellent skill in representing tidal motion, and with observed wind data that compensates for a coarse vertical ocean model resolution. The comprehensive comparison between GNOME and BLOSOM presented here, should aid modelers in interpreting their results. Beyond many similarities, aspects where both models are distinct are highlighted. Some suggestions for improvement are included, e.g., the inclusion of temporal interpolation of the forcing fields (BLOSOM) or the inclusion of a deflection angle option when parameterizing wind-driven processes (GNOME). Overall, GNOME and BLOSOM perform similarly, and are found to be complementary oil spill models. This paper also sheds light on what drove the historical Point Wells spill, and serves the additional purpose of being a learning resource for those interested in oil spill modeling. The increasingly complex approach used for the comparison is also used, in parallel, to illustrate the approach an oil spill modeler would typically follow when trying to hindcast or forecast an oil spill, including detailed technical information on basic aspects, like choosing a computational time step. We discuss our successful hindcast of the 2003 Point Wells oil spill that, to our knowledge, had remained unexplained. The oil spill models' solutions are compared to the historical Point Wells' oil trajectory, in time and space, as determined from overflight information. Our hindcast broadly replicates the correct locations at the correct times, using accurate tide and wind forcing. While the choice of wind coefficient we use is unconventional, a simplified analytic model supported by observations, suggests that it is justified under this study's circumstances. We highlight some of the key oceanographic findings as they may relate to other oil spills, and to the regional oceanography of the Salish Sea, including recommendations for future studies.","2018-09","2025-04-08 17:22:36","2025-04-08 17:22:36","","","","3","6","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","BLOSOM; Foss Barge; GNOME; hindcast; model comparison; ocean trajectory; oil spill model; Point Wells; Salish Sea; windage","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The Digital Video Broadcast Return Channel Satellite (DVB-RCS) NetOps vision for remote management and monitoring aims to provide visibility and Situational Awareness to required communities of interest as well as the ability to view and configure all the operational layers DVB-RCS, including the devices and technology, operations and management, and missions and objectives. An effective management and monitoring solution for DVB-RCS must provide the capability to centrally manage and monitor the system, interoperate between SATCOM and terrestrial networks, consolidate technology, standardize processes, and be proactive rather than reactive. The DISN OSS is DISA's enterprise-wide Service Oriented Architecture for information sharing, management, and monitoring capabilities, based on the Telecommunications Management Network industry standards. The DISN OSS puts the information into the hands of the operators and system managers while making the processes, tools, and technology transparent to the consumer.

The use of the male narrator is inseparably bound up with a number of compromises for the woman writer and for the female reader. But being thus `compromised' through vicariously living the experience of the masculine Other also allows the woman writer privileged insight into the complex processes of justification and rationalisation through which the masculine world-view is engendered and sustained in narrative; it allows her imaginatively to work through, and to see through, the tangle of cause and effect relations which are often illegitimately marshalled into support of that view, and to cast ironical and critical light on them.","2004-04","2025-04-08 17:22:36","2025-04-08 17:22:36","","230-250","","59","","","","","","","","","","","English","","","","","","","Place: CAHIERS VICTORIENS EDOUARDIENS PO 5043, 34032 MONTPELLIER-CEDEX, FRANCE Publisher: UNIV PAUL VALERY Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Satellite remote sensing is the optimal tool to provide such data. Images from Synthetic Aperture Radar (SAR) satellite sensors are preferably used as they work regardless of cloud coverage during image acquisition. However, processing of SAR is more complicated and the sensors have development potential. Dealing with such a complexity, current studies should aim to be reproducible, open, and built upon free and open-source software (FOSS). Thereby, the data can be reused to develop and validate new algorithms or improve the ones already in use. This paper presents a case study of crop classification from microwave remote sensing, relying on open data and open software only. We used 70 multitemporal microwave remote sensing images from the Sentinel-1 satellite. A high-resolution, high-precision digital elevation model (DEM) assisted the preprocessing. The multi-data approach (MDA) was used as a framework enabling to demonstrate the benefits of including external cadastral data. It was used to identify the agricultural area prior to the classification and to create land use/land cover (LULC) maps which also include the annually changing crop types that are usually missing in official geodata. All the software used in this study is open-source, such as the Sentinel Application Toolbox (SNAP), Orfeo Toolbox, R, and QGIS.

However, no traction method using the thread and clip for duodenal ESD as described in this article has been reported to date. We report a case in which traction-assisted ESD using dental floss and a clip was successfully performed on a huge superficial nonampullary duodenal epithelial tumor accompanied by severe fibrosis caused by preoperative biopsies. A 65-year-old woman had a 55-mm flat-elevated tumor in the second part of the duodenum. Severe fibrosis of the submucosal layer was expected due to repeated biopsies at the same site by the patient's previous endoscopist. We selected ESD for this lesion, and the initial incision was started from the side proximal to the lesion, but it was difficult to insert the scope under the submucosal layer directly beneath the biopsy scar. Therefore, traction with an endoclip and dental floss was performed to lift the lesion. Excellent traction allowed safe resection of the fibrotic part under accurate visual observation. Finally, the lesion was resected en bloc without adverse events. Traction-assisted ESD using dental floss and a clip is likely to be an effective adjunctive technique for quick, safe, and successful resection of lesions in the duodenum on which it is difficult to perform ordinary ESD and that have a high probability of intraoperative perforation and massive bleeding.","2019-04","2025-04-08 17:22:36","2025-04-08 17:22:36","","179-181","","2","3","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","dental floss; duodenal endoscopic submucosal dissection; severe fibrosis; superficial nonampullary duodenal epithelial tumor; traction-assisted endoscopic submucosal dissection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bio-Oss (R) is a deproteinized, sterilized bovine bone that has been extensively used in bone regeneration procedures. The aim of the present study was a comparative light, scanning, and electron microscopy evaluation of the interface between Bio-Oss (R) and bone in specimens retrieved after sinus augmentation procedures. Under light microscopy, most of the particles were surrounded by newly formed bone, while in a few cases, at the interface of some particles it was possible to observe marrow spaces and biological fluids. Under scanning electron microscopy, in most cases, the particle perimeter appeared lined by bone that was tightly adherent to the biomaterial surface. Transmission electron microscopy showed that the bone tissue around the biomaterial showed all the phases of the bone healing process. In some areas, randomly organized collagen fibers were present, while in other areas, newly formed compact bone was present. In the first bone lamella collagen fibers contacting the Bio-Oss (R) surface were oriented at 243.73 +/- 7.12 degrees (mean +/- SD), while in the rest of the lamella they were oriented at 288.05 +/- 4.86 degrees (mean +/- SD) with a statistically significant difference of 44.32 degrees (p < 0.001). In the same areas the intensity of gray value was 172.56 +/- 18.15 (mean +/- SD) near the biomaterial surface and 158.71 +/- 21.95 (mean +/- SD) in the other part of the lamella with an unstatistically significant difference of 13.79 (P = 0.071). At the bone-biomaterial interface there was also an electron-dense layer similar to cement lines. This layer had a variable morphology being, in some areas, a thin line, and in other areas, a thick irregular band. The analyses showed that Bio-Oss (R) particles do not interfere with the normal osseous healing process after sinus lift procedures and promote new bone formation. In conclusion, this study serves as a better understanding of the morphollogic characteristics of Bio-Oss (R) and its interaction with the surrounding tissues.

Preliminary method for the A50 road link (Eindhoven-Oss, The Netherlands)","ECOLOGICAL ENGINEERING","","0925-8574","10.1016/S0925-8574(96)00024-9","","After years of efforts to avoid or reduce the impact of infrastructure projects on nature, the principle of ecological compensation has been incorporated in Dutch governmental policy. Ecological compensation aims to recover those ecological functions and natural values that still remain affected after maximum effort has been made to reduce the impact of the intervention (mitigation). The accepted aim of current policy is thus no-net-loss of area and quality by means of mitigative and compensatory measures. As part sf the planning process for construction of a stretch of road in The Netherlands, viz,, the A50 road link in the province of North Brabant, a Nature Compensation Plan (NCP) was required to be drawn up. This work has recently been completed by the Regional Directorate of Public Works and Water Management, the initiator of the intervention. The NCP, initially presented as a Draft Plan, was drawn up by the Regional Directorate using a preliminary method designed by the Centre of Environmental Science of Leiden University for deriving compensatory measures. After an opportunity for public comment, the Draft Plan was revised to form a Final NCP. This article describes, firstly, the preliminary method for deriving ecological compensatory measures. The method starts by quantifying the effects of habitat loss, habitat disturbance (by changes in noise emissions, in the water table and in outdoor recreational patterns), barrier action and fauna casualties. Following mitigation of impacts on nature, compensation for non-mitigable effects focuses successively on area size, derived from the impact on breeding birds, and on area quality, derived from the habitat requirements of the vegetation and fauna groups affected by the road. Guidelines for identifying appropriate locations for compensation are also formulated. Secondly, the compensation method is applied to calculate the mitigative and compensatory measures for the A50 trajectory between Eindhoven and Oss. Thirdly, two comparisons are made: the Draft NCP is compared with the results of the preliminary method, and the Draft and the Final NCP are compared with one another in order to identify the role of the interest groups that played a major role in commenting on the Draft Plan. Finally, realization of the compensatory measures and development of the preliminary method itself are discussed. On the basis of the experience with the A50 case study, a more robust compensation method for road projects is to be developed.","1996-12","2025-04-08 17:22:37","2025-04-08 17:22:37","","327-349","","4","7","","","","","","","","","","English","","","","","","","Place: PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS Publisher: ELSEVIER SCIENCE BV Type: Article; Proceedings Paper","","","","mitigation; barrier action; fauna casualties; habitat disturbance; habitat loss; no-net-loss of area and quality; road infrastructure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of present study was to fully characterize our anorganic bone, InterOss (R), by physical and chemical methods and to compare it with another anorganic bone, Bio-Oss (R) that has been commercially distributed in dental bone graft substitute market since 1995. InterOss (R) anorganic bone had been successfully prepared by chemical treatment (NaOH and H2O2) and low temperature (350 degrees C) annealing process with an extremely low heating rate (<0.3 degrees C min(-1)). Commercially available Bio-Oss (R) anorganic bone was chosen for comparison. The physical and chemical analysis indicated that the pore structure, microstructure, phase structure, and chemical composition of InterOss (R) is substantially equivalent to that of Bio-Oss (R). The BET analysis also showed that the inner surface area of InterOss (R) is comparatively higher than that of Bio-Oss (R). Specially, the protein analysis showed that the content of residual protein of InterOss (R) is relatively lower than that of Bio-Oss (R). Based on an equivalency to Bio-Oss (R) in terms of physical and chemical characterization with both higher inner surface area and lower residual protein content, the InterOss (R) can be a promising candidate as dental bone grafting material in periodontal and maxillofacial surgery.

The antioxidant tea polyphenol (TPP) was embedded into W/O microemulsion, which was further encapsulated into multiple emulsion (Multi-E) together with functional soluble dietary fiber (SDF). The physicochemical properties indicated that the nanoemulsion-based edible film (NEF) improved the morphology of FF and reduced the crystallinity of the film by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water vapor permeability increased gradually and rose to only 0.99% after 5 h, resulting in the water activity of FF at a low level (<= 0.51) during the storage period. The TPP inside was released at a constant rate (<= 18.10%) on the surface, and such a rate was accelerated in the simulated gastrointestinal environment, especially in intestine reaching 60.12% after 5 h of digestion. Besides, the effect of NEF on the flavor was also evaluated and the contents of ketones, phenols, and pyrazines increased, which displayed a regulating effect on the overall flavor of FF by blocking the external moisture and suppressing the microorganism activity. In summary, the NEF effectively enhanced the flavor and taste of FF, controlled the release of TPP, and reduced the water activity during the storage, thereby extending the shelf life.","2022-07","2025-04-08 17:22:37","2025-04-08 17:22:37","","2370-2380","","7","10","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","controlled release; fish floss; nanoemulsion-based edible coating; shelf life; water activity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. Conclusions and Practical Implications. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.","2016-12","2025-04-08 17:22:37","2025-04-08 17:22:37","","974-978","","12","147","","","","","","","","","","English","","","","","","","Place: 211 E CHICAGO AVE, CHICAGO, IL 60611 USA Publisher: AMER DENTAL ASSOC Type: Article","","","","dental floss; allergy; chronic periodontitis; contact hypersensitivity; plasma cell; Treatment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various types of bone graft materials are used after a sinus lift. In our study, a three-dimensional image analysis using a volume analyzer was performed to measure and compare the volume of demineralized bovine bone mineral (Bio-Oss (R)) and carbonate apatite (Cytrans (R)) after a sinus lift, as well as the amount of bone graft material resorption. Patient data were collected from cone-beam computed tomography images taken before, immediately following, and 6 months after the sinus lift. Using these images, both the volume and amount of resorption of each bone graft material were measured using a three-dimensional image analysis system. Results The amount of bone resorption in the Bio-Oss (R)-treated group was 25.2%, whereas that of the Cytrans (R)-treated group was 14.2%. A significant difference was found between the two groups (P < 0.001). Conclusions Our findings indicate that the volume of bone resorption was smaller in the Cytrans (R)-treated group than in the Bio-Oss (R)-treated group, suggesting that Cytrans (R) is more promising for successful implant treatments requiring a sinus lift.","2021-03-23","2025-04-08 17:22:37","2025-04-08 17:22:37","","","","1","7","","","","","","","","","","English","","","","","","","Place: SHIROYAMA TRUST TOWER 5F, 4-3-1 TORANOMON, MINATO-KU, TOKYO, 105-6005, JAPAN Publisher: SPRINGER JAPAN KK Type: Article","","","","Bio-Oss® CBCT; Cone-beam computed tomography; Cytrans® Dental implant; Maxillary sinus augmentation; Sinus lift","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The clip with line traction method was reported to improve ESD. However, there was no comparison with conventional ESD especially for trainees. We report here on the feasibility and efficacy of traction using dental floss with endoscopic clip to facilitate ESD versus conventional method for ESD trainees. Twenty simulated gastric lesions, paired with location and size, were created in porcine stomachs using a standard template. After a circular incision was made, submucosal dissection (control, n = 10) was performed with standard ESD, while the study (clip, n = 10) was performed with traction using dental floss and endoclip. Primary outcome was speed of submucosal dissection. Secondary outcome included frequency of submucosal injection and adverse event. Compared with controls, median procedure time was significantly shorter in the clip group (5.6 +/- A 1.1 vs. 13.6 +/- A 2.5 min, P = 0.003), with a significantly faster submucosal dissection time (1.8 +/- A 0.3 vs. 0.6 +/- A 0.1 cm(2)/min, P = 0.001) and less frequent submucosal injection (5.7 +/- A 0.6 vs. 8.5 +/- A 1.0 times, P = 0.024). There were no perforations in either group, but less adverse events (bleeding and injury to muscularis propria) in the clip group (1 vs. 7, P = 0.068, alpha = 0.1).

The purpose of this study was to radiologically evaluate the efficacy of using Bio-Oss Collagen with Concentrated Growth Factor (CGF) as grafting materials for OSFE with simultaneous implant placement in the atrophic maxilla after one year of functional loading.MethodsA total of 126 implants were placed for 123 patients. Our inclusion criteria were patients with Residual Bone Height (RBH) <= 5 whom underwent OSFE procedure and simultaneous implant placement with different grafting materials: Group A with no grafting materials, Group B with Bio-Oss bone graft, and Group C with Bio-Oss Collagen with CGF. The Implants Survival Rate (ISR) was the primary outcome variable. Secondary outcome variables included radiographic measurements assessed at four follow-up time points, the Implant Stability Quotient (ISQ), and bone density (B). Indicators of bone formation were compared at different time points. Appropriate statistical analyses were conducted, with statistical significance set at a P value of 0.05 for all tests.ResultsISR was 96%. A significant positive relationship was found between RBH and ISR, [r (126) = .359, p = .000]. Endo sinus bone gain indictors increased in both grafted groups as compared to the non-grafted group. Total Bone Resorption (TBR1) and (TBR2) significantly decreased in both grafted groups compared to the non-grafted group (P = .004, P = .000). Graft size (D) was a positive predictor for ISR at three time points: D0 (odds ratio [OR] 8.06; 95% CI 1.59 to 38.24; P = .010); D1 (OR 96.58; 95% CI 1.69 to 5.52; P = .027); D2 (OR 4.97; 95% CI 1.29 to 19.19; P = .020).

With advances in digital planning, surgical techniques, orthognathic surgery becomes increasingly safe, however, still a physiological factor that challenges the surgeon: bone repair. The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss (R) Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss (R)) and 10% collagen fibres in a block form and is sterilized by gamma-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss (R) Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss (R) Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.","2023-09-10","2025-04-08 17:22:37","2025-04-08 17:22:37","","","","","5","","","","","","","","","","English","","","","","","","Place: FLAT-RM C 16F, KINGS WING PLAZA 1, NO 3 KWAN ST, SHATIN, HONG KONG 00000, PEOPLES R CHINA Publisher: AME PUBLISHING COMPANY Type: Article","","","","biomaterial; Bio-Oss (R) Collagen; case report; orthognathic; Orthognathic surgery; pseudoarthrosis treatment; vertical chin augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Effective regeneration of bone defects resulting from peri-implantitis is crucial to maintaining the functionality of dental implants. Purpose of the Study: The study aimed to compare the effectiveness of fine-particle dentin and Bio-Oss in the reconstruction of bone defects caused by peri-implantitis. Materials and Methods: The study included a comprehensive radiological assessment of changes in bone density over time. Bone density was assessed using Hounsfield Units (HUs) as a measure of bone attenuation, with radiological assessments performed at 8- and 12-week intervals during the healing process. The study included participants ranging in age from 30 to 65 years. Fifty-seven patients were divided into three groups: 22 patients received small-particle dentin, 15 received Bio-Oss, and 20 controls without bone substitute material. Results: The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine dentin group, 85% in the Bio-Oss group, and 70% in the control group. The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine-dentin group, 85% in the Bio-Oss group, and 70% in the control group. Conclusions: Both fine-particle dentin and Bio-Oss significantly improved bone density compared to the control group.

Method and Result: A 77-year-old woman with a non-healing anteromedial chest wound presented with sudden hypotension and hemoptysis. The computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of ascending aorta, with sternal erosion close to the wound. Conventional open repair was not preferred due to possible contamination of interposition graft and difficult sternum closure. The feasibility of endografting was confirmed based on appropriate landing zones. After endografts modification at back table, we made a left minithoracotomy and establish a through-and-through body floss wire from left ventricular apex to femoral artery. Retrograde delivery over this wire from femoral artery to ascending aorta and deployment of endografts under rapid ventricular pacing support were performed smoothly. Final angiography showed no endoleaks with patent coronary and arch vessels. Further wound debridement was done at the same time and wound culture yielded tuberculosis. After completing anti-tuberculosis therapy, no recurrent infection occurred. Postoperative 6-month CT scan disclosed optimal result. Conclusion: With adequate landing zones and delicate surgical strategy, endografting with anti-tuberculosis therapy may be an alternative treatment for ascending aortic tuberculosis pseudoaneurysm.","2017-11","2025-04-08 17:22:37","2025-04-08 17:22:37","","","","","45","","","","","","","","","","English","","","","","","","Place: 360 PARK AVE SOUTH, NEW YORK, NY 10010-1710 USA Publisher: ELSEVIER SCIENCE INC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community - eZ Publish we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm. In addition, the results of our study highlight the central importance of an integrative IT platform in boundary management activities. (C) 2014 Elsevier Ltd.

We conducted a large, multicenter, prospective, observational study to confirm the REGOMA data in a real-world setting. Patients and methods: The major inclusion criteria were histologically confirmed diagnosis of glioblastoma according to the World Health Organization (WHO) 2016 classification and relapse after radiotherapy with concurrent/adjuvant temozolomide treatment, good performance status [Eastern Cooperative Oncology Group performance status (ECOG PS 0-1)] and good liver function. Regorafenib was administered at the standard dose of 160 mg/day for 3 weeks on/1 week off. Brain magnetic resonance imaging was carried out within 14 days before starting regorafenib and every 8-12 weeks. The primary endpoint was overall survival (OS). The secondary endpoints were progression -free survival (PFS), objective response rate, disease control rate (DCR), safety and health-related quality of life. The Response Assessment in Neuro-Oncology (RANO) criteria were used for response evaluation and Common Terminology Criteria for Adverse Events (CTCAE) version 5 for assessment of adverse events (AEs). Results: From September 2020 to October 2022, 190 patients with recurrent glioblastoma were enrolled from 30 cancer centers in Italy: their median age was 58.5 years [interquartile range (IQR) 53-67 years], 68% were male and 85 (44.7%) were in optimal clinical condition (ECOG PS 0). The number of patients taking steroids at baseline was 113 (60%); the second surgery was carried out in 39 (20.5%). O6-methylguanine-DNA methyltransferase (MGMT) was methylated in 80 patients (50.3%) and 147 (92.4%) of the patients analyzed had isocitrate dehydrogenase (IDH) wild type. The median follow-up period was 20 months (IQR 15.6-25.5 months). The median OS was 7.9 months ([95% confidence interval (CI) 6.5-9.2 months] and the median PFS was 2.6 months (95% CI 2.3-2.9 months). Radiological response was partial response and stable disease in 13 (7.3%) and 26 (14.6%) patients, respectively, with a DCR of 21.9%. The median number of regorafenib cycles per patient was 3 (IQR 2.0-4.0). Grade 3-4 drug-related adverse events were reported in 22.6% of patients. A dose reduction due to AEs was required in 36% of patients. No deaths were considered as treatment-related AEs.

We aimed to compare the impact of early palliative care including formal concertation with oncologists on decision for an additional line of chemotherapy compared with usual oncology care. Methods This randomized prospective study enrolled adult women with metastatic breast cancer and visceral metastases with a 3rd- or 4th-line chemotherapy (CT). Patients received usual oncology care with a palliative care consultation only upon patient or oncologist request (standard group, S) or were referred to systematic palliative care consultation including a regular concertation between palliative care team and oncologists (early palliative care group, EPC). The primary endpoint was the rate of an additional CT (4th or 5th line) decision. Quality of life, symptoms, social support and satisfaction were self-evaluated at 6 and 12 months, at treatment discontinuation or 3 months after discontinuation. Results From January 2009 to November 2012, two authorized cancer centers included 98 women (EPC: 50; S: 48). Thirty-seven (77.1%, 95%CI 62.7-88%) patients in the EPC group had a subsequent chemotherapy prescribed and 36 (72.0%, 95%CI 57.5-83.8%) in the S group (p = 0.646). No differences in symptom control and global quality of life were observed, but less deterioration in physical functioning was reported in EPC (EPC: 0 [- 53-40]; S: - 6; 7 [- 60 to - 20]; p = 0.027). Information exchange and communication were significant improved in EPC (exchange, EPC: - 8.3 [- 30 to + 7]; S: 0.0 [- 17 to + 23]; p = 0.024; communication, EPC: 12.5 [- 8 to - 37]; S: 0.0 [- 21 to + 17]; p = 0.004). Conclusion EPC in metastatic breast cancer patients did not impact the prescription rate of additional chemotherapy in patients a 3rd- or 4th-line chemotherapy for metastatic breast cancer; however, EPC may contribute to alleviate deterioration in physical functioning, while facilitating communication.","2023-01","2025-04-08 17:22:38","2025-04-08 17:22:38","","","","1","31","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Advanced breast cancer; Chemotherapy; Early palliative care; Supportive care","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on the results of the ISG/OS-1 study, the MAP regimen (methotrexate [MTX], doxorubicin [ADM] and cisplatin [CDP] with the addition of ifosfamide [IFO] in poor-responder patients) was investigated in patients with nonmetastatic osteosarcoma of the extremity (ISG/OS-Oss study). Patients and methods. Compared with the ISG/OS-1 study (cumulative doses: ADM 420 mg/m(2), MTX 120 g/m(2), CDP 600 mg/m(2), IFO 30 g/m(2)), the ISG/OS-Oss study reduced the number of MTX cycles from 10 to 5 (cumulative MTX dose: 60 g/m(2)) in order to diminish treatment duration and toxicity. Results. From January 2007 to June 2011, 171 patients (median age 16 years, 60% males) were registered. The limb salvage rate was 94% and the good pathologic response rate 51% (these figures were 92% and 48%, respectively, in the ISG/OS-1 study). At a median follow-up of 39 months (range, 4-80), the 5-year overall survival rate was 80% (95% CI, 73%-87%) and the event-free survival was 50% (95% CI, 39%-59%). For comparison, the 5-year overall and event-free survival rates in ISG/OS-1 were 73% (95% CI, 65%-81%) and 64% (95% CI, 56%-73%), respectively. Conclusions. This study confirms that in nonmetastatic osteosarcoma of the extremity, conservative surgery in more than 90% and a good pathologic response rate of 50% can be expected with primary chemotherapy based on the MAP regimen. The response and resection rates in the ISG/OS-Oss study are in the same range as those of the previous study, whereas the event-free survival is lower than that previously achieved. Since the only difference between the two studies was the cumulative dose of postoperatively given MTX, our data support the importance of the cumulative dose of MTX in the MAP regimen.","2014-12","2025-04-08 17:22:38","2025-04-08 17:22:38","","612-619","","6","100","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","methotrexate; neoadjuvant chemotherapy; osteosarcoma; tumor necrosis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Anorganic bovine bone (Bio-Oss) has been reported to be osteoconductive, and no inflammatory responses have been observed with the use of this biomaterial. One of the main questions pertaining to Bio-Oss concerns its biodegradation and substitution by host bone. Some investigators have observed rapid replacement by host bone, while other researchers observed slow resorptive activity or no resorption at all. The aim of the present study was to conduct a long-term histologic analysis of retrieved specimens in humans where Bio-Oss was used in sinus augmentation procedures. Specimens were retrieved from 20 patients after varying peri ods from 6 months to 4 years and were processed to obtain thin ground sections. Bio-Oss particles were surrounded for the most part by mature, compact bone. In some Haversian canals it was possible to observe small capillaries, mesenchymal cells, and osteoblasts in conjunction with new bone. No gaps were present at the interface between the Bio-Oss particles and newly formed bone, in specimens retrieved after 18 months and 4 years, it was also possible to observe the presence of osteoclasts in the process of resorbing the Bio-Oss particles and neighboring newly formed bone. Bio-Oss appears to be highly biocompatible and osteoconductive, is slowly resorbed in humans, and can be used with success as a bone substitute in maxillary sinus augmentation procedures.","1999-12","2025-04-08 17:22:38","2025-04-08 17:22:38","","835-840","","6","14","","","","","","","","","","English","","","","","","","Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC Type: Article","","","","anorganic bovine bone; biomaterials; sinus augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Three scaffolds, group A (seeded with BMSCs/bFGF), B (seeded with BMSCs/pVAX1) and C (cell-free), which had been cultured in vitro under standard cell culture conditions for 18 days, were implanted into mandibular defects under sterile conditions. Animals were sacrificed by anesthesia overdose 12 weeks following surgery and the scaffolds were extracted for bone mineral density and histological analyses. Results indicate that bFGF was successfully transfected into BMSCs. Proliferation and osteoblast differentiation of BMSCs were stimulated by bFGE: in vitro. No differences were identified in surface morphology for Bio-Oss loaded with variable groups of cells. At week 12 following implantation of Bio-Oss scaffolds, mineralization of BMSCs in Bio-Oss scaffolds was observed to be increased by bFGF. New bone and cartilage formation was revealed in hematoxylin and eosin-stained sections in Bio-Oss scaffolds and was most abundant in group A (BMSCs transfected with bFGF). In the current study, the bFGF gene was transfected into BMSCs and expressed successfully. bFGF promoted proliferation and differentiation of BMSCs in vitro and implantation of bFGF-expressing BMSCs combined with Bio-Oss enhanced new bone regeneration more effectively than traditional methods.","2013-01","2025-04-08 17:22:38","2025-04-08 17:22:38","","99-104","","1","7","","","","","","","","","","English","","","","","","","Place: POB 18179, ATHENS, 116 10, GREECE Publisher: SPANDIDOS PUBL LTD Type: Article","","","","Bio-Oss; basic fibroblast growth factor; bone marrow stromal cells; mandibular defect","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This involved a total of 15 sinus floor elevation procedures being carried out on 11 patients (average age of 49.6 years) according to the technique described by Tatum (1986). The subantral sinus cavity was augmented using bovine apatite combined with venous blood. After an average healing phase of 6.8 months, trephine burrs were used to take 22 bone biopsies from the augmented sinus region. Then 38 Branemark(R) implants were inserted in both the osteotomies resulting from bone sampling and in regular sites in the augmented posterior maxilla. Histomorphometric analysis of ground sections from the bone biopsies prepared according to the standard method of Donath & Breuner (1982) produced an average percentage of newly-formed bone of 14.7% (+/-5.0%) and a proportion of residual xenogenic bone substitute material of 29.7% (+/-7.8%). Some 29.1% (+/-8.1%) of the surface of the Bio-Oss(R) granulate was in direct contact with newly-formed bone. Histologically, newly-developed bone became evident, partly invaginating the particles of apatite and forming bridges in the form of trabeculae between the individual Bio-Oss(R) particles. Despite the absence of osteoclastic activity, the inward growth of bone indicates slow resorption of the xenogenic bone graft material. When the implants were uncovered, after an average healing phase of 6 months, 4 of the 38 implants had become loose. Of these 4 implants, 1 had to be subsequently explanted, while the others remained as “sleeping implants” and were not included in the implants superstructure.

Methods Medical records of Department of Oral and Maxillofacial Surgery of Shandong Provincial Hospital were screened for patients who had been treated with immediate implant implantation in the esthetic area using either MC (Allgens (R), Beijing Allgens Medical Science and Technology Co., Ltd., China) or Bio-Oss (Bio-Oss (R), Geistlich Biomaterials, Wolhusen, Switzerland), between January 2018 and December 2019. All patients fulfilling the in-/exclusion criteria and following followed for a minimum period of 1 year after surgery were enrolled into the presented study. Implant survival rate, radiographic, esthetic and patient satisfactory evaluations were performed. Results Altogether, 70 patients were included in the study; a total of 80 implants were inserted. All implants had good initial stability. The survival rate of implants was 100% at 1-year follow-up. The differences in horizontal and vertical bone loss between the MC group (0.72 +/- 0.26 mm, 1.62 +/- 0.84 mm) and the Bio-Oss group (0.70 +/- 0.52 mm, 1.57 +/- 0.88 mm) were no significant difference statistically no significant 6 months after permanent restoration. Similar results occurred at 12 months after permanent restoration functional loaded. Clinical acceptability defined by pink esthetic score (PES) >= 6 (6.07 +/- 1.62 vs. 6.13 +/- 1.41) was not significantly different between groups. Patient satisfaction estimated by visual analog scale (VAS) was similar (8.56 +/- 1.12 vs. 8.27 +/- 1.44), and the difference was no significant difference between the two groups.

To assess this issue, this paper describes a real-time root cause analysis mechanism, which can pinpoint an accurate root cause and identify the influence on services. We investigated an interworking mechanism; based on a web service interface between an inventory and fault management systems and developed prototypes of them as part of an operation support system (OSS), which is capable of managing not only a core network and a metro ring network, but also a customer network. By introducing a hierarchical circuit model in the inventory management system and the proposed scanning algorithm over multiple layers and domains implemented in the fault management system, our developed root cause analysis was successfully verified using the testbed network environment; indicating relatively fast and scalable operation.","2009","2025-04-08 17:22:39","2025-04-08 17:22:39","","141-144","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IFIP; IEEE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Long-term follow-up of implants placed in BCP after sinus augmentation is still missing. Purpose: The primary aim of the study was to compare survival rates and marginal bone loss of Straumann SLActive implants placed in either BCP (test) or Bio-Oss (R) (DBB) (control) after sinus floor augmentation. The secondary aim was to calculate graft sinus height at different time points. Materials and Methods: Bilateral sinus floor augmentation was performed in a split mouth model. Eleven patients (mean age 67 years) received 100% BCP on one side and 100% DBB on the contralateral side. After 8 months of graft healing, 62 Straumann SLActive implants were placed. After 5 years of functional loading (6 years after augmentation) of implants, marginal bone levels and grafted sinus height were measured, and implant survival and success rates were calculated. Results: After 5 years of loading, all prosthetic constructions were in function although two implants were lost in each grafting material. The overall implant survival rate was 93.5% (91.7% for BCP, 91.3% for DBB, and 100% for residual bone). The success rates were 83.3% and 91.3% for BCP and DBB, respectively. There was no statistically significant difference in mean marginal bone level after 5 years between BCP (1.4 +/- 1.2 mm) and DBB (1.0 +/- 0.7 mm). Graft height reduction (GHR) after 6 years was limited to 6.6% for BCP and 5.8% for DBB. Conclusion: In this limited RCT study, the choice of biomaterial used for sinus floor augmentation did not seem to have any impact on survival rates and marginal bone level of the placed implants after 5 years of functional loading and GHR was minimal.","2016-10","2025-04-08 17:22:39","2025-04-08 17:22:39","","926-936","","5","18","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","biphasic calcium phosphate; bone substitutes; deproteinized bovine bone; sinus floor augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we evaluated biopsies of grafted bone with a mixture of autologous bone and Bio-Oss((R)) or BoneCeramic((R)) after two different healing time periods to understand the molecular process underlying bone formation after MSFE. Material and methodsSeven patients, following a bilateral split-mouth design model and needing a MSFE to allow implant placement, were recruited for this study. Right or left sinuses were grafted with autologous maxillary bone combined either with Bio-Oss((R)) or BoneCeramic((R)), respectively. Twenty biopsies were taken at the time of implant insertion after 4-5months or 6-8months of MSFE, and analyzed by micro-computed tomography (microCT) and gene-expression analysis. ResultsMicroCT analysis revealed no differences in the morphometric parameters or BMD either after 4-5months or 6-8months of MSFE between Bio-Oss((R)) and BoneCeramic((R)). At molecular level, a higher expression of bone forming gene Runx2 was observed after 4-5months of MSFE in the Bio-Oss((R)) compared with the BoneCeramic((R)) group. ConclusionsOur results indicate that differences found at the molecular level between Bio-Oss((R)) and BoneCeramic((R)) are not translated to important differences in the 3D microstructure and BMD of the grafted bone.","2015-06","2025-04-08 17:22:39","2025-04-08 17:22:39","","727-735","","6","26","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","bone graft; clinical study; dental implant; gene expression; maxillary sinus floor elevation (MSFE); micro-computed tomography (microCT)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, patient's perception of recovery and satisfaction with the surgical intervention are rarely reported. The objective of the present randomized controlled trial was to assess patient's perception of recovery after osteotome-mediated sinus floor elevation with Bio-Oss collagen compared with no grafting material. Forty healthy patients were randomly allocated to Bio-Oss collagen or no grafting material. Oral health-related quality of life was assessed by Oral Health Impact Profile-14 at enrollment. Patient's perception of recovery was assessed by self-administrated questionnaires and visual analog scale evaluating pain, social and working isolation, physical appearance, duration and quality of life alterations, eating and speaking ability, diet variations, and sleep impairment after 1 week and 1 month, respectively. Descriptive statistics was expressed as mean percentage with standard deviation. Correlation between impaired oral health-related quality of life, age, gender, and recovery were assessed by T test. Level of significance was 0.05. Results Osteotome-mediated sinus floor elevation is associated with high patient satisfaction, limited postoperative discomfort, and willingness to undergo similar surgery. Influence on patient's daily life activities seems to be minimal and limited to the first postoperative days. Most patients managed to return to work and their routine daily activities after 0-2 days. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery. However, number of days with pain, eating difficulties, and sleep disturbances were significantly increased with Bio-Oss collagen compared with no grafting material (P<0.05).

The LIG sensors are fabricated on polyimide (PI) Flexible Printed Circuit Board (FPCB) through CO2 infrared laser direct-write method. The LIG sensors provide repeatable high-precision temperature sensing, humidity measurement, and strain detection capability. The temperature sensing characterization shows the resistive LIG sensor has a sensitivity of -0.0493 %/degrees C, the linear fit R-square factors = 0.9973 across -40 degrees C to 125 degrees C. The capacitive humidity sensor achieves a normalized response of 2260% at 95% relative humidity (RH). Our proposed AFE chip contains a hybrid folded-cascode Operational Amplifier (OPAMP) with 92 dB gain and 12.5 MHz Gain Bandwidth Product (GBW), and a 14-bit 10 MHz Successive Approximation Register Analog-to-Digital Converter (SAR ADC). Designed using open-source analog flow and fabricated in GF180 OpenPDK, the AFE chip serves as a flexible and universal readout platform, adaptable for various sensing applications. A real-time demonstration of finger bending detection, with readings output by the AFE Chip, is performed to validate the system functionalities and robustness. The temperature, humidity, strain sensing capability provide by the wearable system are attractive for personal healthcare application.

When the capacity was 0.4 g (CA0.4), MS/Bi2O3 @Cu-MOF showed good photocatalytic activity, and the inactivation rate of M. aeruginosa reached 74.462% after 120 h. MS/Bi2O3 @Cu-MOF-CA0.4 showed a large specific surface area of 30.490 m2/g and an average pore size of 22.862 nm, belonging to mesoporous materials. After 120 h of treatment, the content of soluble protein in the MS/Bi2O3 @Cu-MOF-CA0.4 treatment group decreased to 0.365 mg/L, the content of chlorophyll a (chla) was 0.023 mg/L, the content of malondialdehyde (MDA) increased to 3.168 nmol/mgprot, and the contents of various antioxidant enzymes experienced drastic changes, first increasing and then decreasing. The photocatalytic process generated center dot OH and center dot O2-, which played key role in inactivating the algae cells. Additionally, the release of Cu2+ and adsorption of the material also contributed to the process.","2024-03-05","2025-04-08 17:22:39","2025-04-08 17:22:39","","","","","465","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Algae inactivation; Crosslinking reaction; Floating carrier; Microcystis aeruginosa; Photocatalysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We retrospectively collected data on advanced NSCLC not receiving a first-line platinum combination, focusing on clinical selection criteria. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor performance status. A single agent chemotherapy was offered with the prevalence of oral metronomic vinorelbine. In the whole population, progression-free survival and overall survival ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. Limited evidence is available concerning the selection criteria and the outcomes of platinum unfit newly diagnosed advanced NSCLC patients receiving single-agent chemotherapy. We retrospectively collected data on consecutive, stage IIIB-IV, EGFR/ALK negative and PD-L1 < 50% NSCLC patients treated with first-line single agent chemotherapy. Baseline characteristics, outcome measures and toxicities were recorded, as well as criteria according to which treatment selection was made and what percentage of patients did not receive a first-line platinum-based chemotherapy. Two-hundred and twenty-one patients were included. Median age was 79 (range 56-92) years, M/F 165(74.6%)/56(25.4%), ECOG performance status (PS) 0/1/ >= 2 23(10.9%)/94(42.5%)/103(46.6%), with a median of two serious comorbidities. A median of 25% (range 10%-30%) of newly diagnosed NSCLC did not receive a first-line platinum combination. Clinical criteria according to which decision was made were older age (76.5%), comorbidities (72%), poor PS (55.2%) and familiar or social issues (10%). Single-agent treatment consisted of oral metronomic vinorelbine (MetV 78.6%), gemcitabine (Gem 10%), oral standard vinorelbine (Vin 8.2%) and other (O 3.2%). Median progression-free survival (PFS) and overall survival (OS) of single agent treatments ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. All grade toxicities did not differ among single agents, while grade 3-4 toxicities were less frequent with MetV. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor PS. An oral treatment was frequently proposed with MetV being the most frequent choice according to its safety profile.","2022-12","2025-04-08 17:22:39","2025-04-08 17:22:39","","","","24","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","elderly; low performance status; metronomic; non-small cell lung cancer; single agent chemotherapy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, controversy exists regarding the need to cover the lateral osteotomy site with a membrane. Also, the healing period before loading remains undefined when machined-surface implants are placed. Twenty-nine patients showing reduced bone volume in the posterior maxilla had 61 Branemark System implants placed in 30 sinuses augmented with a lateral osteotomy approach. Sinuses grafted with Bio-Oss and covered with a collagen membrane Bio-Gide (M+) received 29 implants, while grafted but uncovered sites (M-) received 32 implants. An immediate procedure was followed to place 41 implants and a staged procedure was used for 20 implants, Abutment connection was made in 2 distinct postoperative periods: 6 to 9 months and over 9 months. The patients were followed for an average of 22.4 months. The survival rate of the implants was dependent on the postoperative healing time and membrane presence. In case of the immediate procedure and in M- sites, when residual bone height was less than 5 mm, more failures occurred when the loading was done at 6 to 9 months than after 9 months. No failures occurred in the M- series when a staged approach was followed. The overall survival rate was 78.1% for the M- sites and 93.1% for the M+ sites. No failures occurred (0/35) in the control implants placed in adjacent native bone. Implant survival rate was related to the quality of the reconstructed cortical plate and to implant length. The concomitant use of a collagen barrier to cover the osteotomy site, when machined-surface implants were used in sinus grafting, seemed to improve the quality of the graft healing and survival rate of the implants loaded between 6 and 9 months after placement.","2001-10","2025-04-08 17:22:39","2025-04-08 17:22:39","","713-721","","5","16","","","","","","","","","","English","","","","","","","Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC Type: Article","","","","bone grafting; endosseous dental implants; maxillary sinus; membranes","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the evaluation of its success is limited to histological analysis, and its effects on mechanical hardness remain to be investigated. This study investigated mechanical strength in support of histological findings, specifically for tissue-engineered bone with mesenchymal stem cells (MSCs) and platelet-rich-plasma (PRP). Initially, teeth were extracted, and bone defects on both sides of the mandible were prepared with a trephine bar. The defects were implanted by using the following graft materials: 1) PRP, 2) PRP and dog MSCs (dMSCs), 3) autogenous bone (PCBM), 4) bone substitute (Bio-Oss (R)), and 5) control (defects only). After 2, 4, 8, and 12 weeks of implantation, the defects were histologically assessed to examine their mechanical properties. According to histological observations, the dMSCs/PRP groups had well-formed mature bone compared with the control (defects only), Bio-Oss (R), and PRP groups. The Vickers hardness test values were 8 (control), 9 (PRP), not detected (Bio-Oss (R)), 11 (PCBM), and 17 (dMSCs/PRP) after 2 weeks. Therefore, tissue-engineered bone can be used for early stage bone regeneration from the viewpoint of histology and mechanical properties.

This practice often renders the product superior to more centralized models such as those used in commercial software companies. How is such a phenomenon possible in a time where nothing seems to be acquirable save by purchase? Niels C. TAUBERT's book Productive Anarchy? Networks of Open Source Software Development aims at a sociological understanding of the prerequisites and conditions for the success of open source software. One of the conclusions of TAUBERT's book is that the process of open software development needs to be understood as adaptive and experimental. A continuous feedback between the context of production and the context of application is the basis for robust and successful software production. One of the surprising results of the book is that the most important requirement for this feedback process is a set of norms-neutrality, communism, disinterestedness, and universalism-norms that Robert MERTON associated with academic science in the 1940s. If TAUBERT is right that these norms are to be found outside the world of institutional science in open source software development projects today, then his case study can be seen as an indicator for a new form of knowledge production in the 21st century, where the social relevance and responsibility of a research process are keys to successful innovation. With this book, which deserves a wide readership, TAUBERT makes an important contribution to our understanding of the successful organization of technology development. References.

It is argued that the success of this new innovation model is greatly facilitated by a well balanced portfolio of intrinsic & extrinsic motivation, low costs for contributors & governance mechanisms that do not crowd out intrinsic motivation. 96 References.

For the OSS projects to stay sustainable, i.e., viable and maintained over time without interruption or weakening, maintenance labor requires an underlying infrastructure to be supported and secured. Aims: Using the construct of human infrastructure, our study aims to investigate how maintenance labor can be supported and secured to enable the creation and maintenance of sustainable OSS projects, viewed from the maintainers’ perspective. Method: In our exploration, we interviewed ten maintainers from nine well-adopted OSS projects. We coded the data in two steps using investigator-triangulation. Results: We constructed a framework of infrastructure design that provide insight for OSS projects in the design of their human infrastructure. The framework specifically highlight the importance of human factors, e.g., securing a work-life balance and proactively managing social pressure, toxicity, and diversity. We also note both differences and overlaps in how the infrastructure needs to support and secure maintenance labor from maintainers and the wider OSS community, respectively. Funding is specifically highlighted as an important enabler for both types of resources. Conclusions: The study contributes to the qualitative understanding of the importance, sensitivity, and risk for depletion of the maintenance labor required to build and maintain healthy OSS projects. Human infrastructure is pivotal in ensuring that maintenance labor is sustainable, and by extension the OSS projects on which we all depend.","2024","2025-04-08 17:24:50","2025-04-08 17:24:50","","37–48","","","","","","","ESEM '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Barcelona, Spain","","","","Open Source Software; Human Factors; Sustainability; Community Health; Maintainers; Project Health","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.","2023","2025-04-08 17:24:50","2025-04-08 17:58:49","","180–190","","","","","","","dg.o '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Gda?sk, Poland","","","","GitHub; open source software; government; barriers; benefits; citizen engagement; evidence","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Substantial research was done to investigate central projects such as Linux kernel but we have only a limited understanding of how the periphery of the larger OSS ecosystem is interconnected through technical dependencies, code sharing, and knowledge flows. We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-08 17:24:50","2025-04-08 17:24:50","","3","","","","","","","ESEC/FSE 2019","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Tallinn, Estonia","","","","Software Ecosystems; Empirical Software Engineering; Software Measurement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors’ learning processes is an important research area in OSS.This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education.

To bridge this gap, we undertook a large-scale data-driven study to understand how decisions are made in an OSSD community, using the case study of Python Enhancement Proposals (PEPs), which embody decisions made during the evolution of the Python language. Our main contributions are:(a) the design and development of a framework using information retrieval and natural language processing techniques to analyze the Python email archives (comprising 1.48 million emails), and(b) the extraction of decision-making processes that reveal activities that are neither explicitly mentioned in documentation published by the Python community nor identified in prior research work.

Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSS coach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process.

We conducted a pilot diary study to explore motivations, barriers, and the contribution processes of first-time contributors in a real time, qualitative manner. In addition, we measured their self-efficacy before and after their participation. We found that what drove participants were intrinsic motivations, altruism, and internal values, which differed from previous work with older adults and with the general FOSS population. We also found that self-efficacy did not change significantly, even when participants encountered significant barriers or setbacks. The top 3 barriers were lack of communication, installation issues, and documentation issues.

We refer to the production of software primarily for the benefit of developers as reflexivity, and we evaluate the applicability of this concept to open source software (OSS) by studying SourceForge projects. Objective: The goal of this research is to test Eric Raymond's assertions with respect to OSS success factors. Method: We present four criteria by which to assess project reflexivity in SourceForge. These criteria are based on three specific indicators: intended audiences, relevant topics, and supported operating systems. Results: We show in this short paper that 68% of SourceForge projects are likely reflexive (in the sense described by Raymond). Further, 76% of projects exceeding one million downloads are reflexive, 79% for projects exceeding ten million downloads, and 89% for projects exceeding one hundred million downloads. Conclusion: These results tentatively support Raymond's assertions that 1) OSS projects tend to be reflexive and 2) reflexive OSS projects tend to be more successful than irreflexive projects.

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization that naturally fix them during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-08 17:25:09","2025-04-08 18:14:17","","97–106","","","","","","","DSN '00","","","","IEEE Computer Society","USA","","","","","","","","","","","","Software; Faults; Heisenbugs; Recovery; Transient","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Structural complexity, an architectural concern, makes software projects more difficult to understand, and consequently more difficult to maintain and evolve. The contributors in a free software project exhibit different levels of participation in the project, and can be categorized as core and peripheral developers. Research aim: This research aims at characterising the changes made to the source code of 7 web server projects written in C with respect to the amount of structural complexity added or removed and the developer level of participation. Method: We performed a observational study with historical data collected from the version control repositories of those projects, recording structural complexity information for each change as well as identifying each change as performed by a core or a peripheral developer. Results and conclusions: We have found that core developers introduce less structural complexity than peripheral developers in general, and that in the case of complexity-reducing activities, core developers remove more structural complexity than peripheral developers.

The primary difficulty is that software development efforts are complex in terms of both the technical and social aspects of the engineering environment. This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data.

Companies get involved in FLOSS projects to acquire user innovations [3, 12], to reduce costs [8, 11], to make money on complementary services [13], etc. Such intense involvement may change the nature of FLOSS development and pose critical challenges for the sustainability of the projects. For example, it has been found that a company's full control and intense involvement is associated with a decrease of volunteer inflow [13]. Sometimes a project may fail after one company pulls resources from the project [13]. This raises concerns about the domination of one company in a project. In large projects like OpenStack, there are often hundreds of companies involved in contributing code. Despite substantial researches on commercial participation, whether or not one company dominates a project and the impact of such domination has never been explicitly explored. We investigate four main projects of OpenStack, a large ecosystem that has had a tremendous impact on computing and society, to answer the following research questions: Does one company dominate the project's development (RQ1)?

Recent research has linked these problems to the values of Lyapunov exponents for the forward-dynamics, which describe the growth or shrinkage of infinitesimal perturbations. Here, we propose gradient flossing, a novel approach to tackling gradient instability by pushing Lyapunov exponents of the forward dynamics toward zero during learning. We achieve this by regularizing Lyapunov exponents through backpropagation using differentiable linear algebra. This enables us to ""floss"" the gradients, stabilizing them and thus improving network training. We demonstrate that gradient flossing controls not only the gradient norm but also the condition number of the long-term Jacobian, facilitating multidimensional error feedback propagation. We find that applying gradient flossing prior to training enhances both the success rate and convergence speed for tasks involving long time horizons. For challenging tasks, we show that gradient flossing during training can further increase the time horizon that can be bridged by backpropagation through time. Moreover, we demonstrate the effectiveness of our approach on various RNN architectures and tasks of variable temporal complexity. Additionally, we provide a simple implementation of our gradient flossing algorithm that can be used in practice. Our results indicate that gradient flossing via regularizing Lyapunov exponents can significantly enhance the effectiveness of RNN training and mitigate the exploding and vanishing gradients problem.","2023","2025-04-08 17:25:10","2025-04-08 17:25:10","","","","","","","","","NIPS '23","","","","Curran Associates Inc.","Red Hook, NY, USA","","","","","","","","event-place: New Orleans, LA, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper builds on previous work about defining success in FLOSS projects by taking a collective action perspective. We first report the results of interviews with FLOSS developers regarding our ideas about success and failure in FLOSS projects. Building on those interviews and previous work, we then describe our criteria for defining success/tragedy in FLOSS commons. Finally, we discuss the results of a preliminary classification of nearly all projects hosted on Sourceforge.net as of August 2006.","2007","2025-04-08 17:25:10","2025-04-08 17:40:10","","11","","","","","","","FLOSS '07","","","","IEEE Computer Society","USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Meanwhile, software companies have successfully launched programs like Google Summer of Code (GSoC) and FindBugs ""fixit"" to contribute to open-source projects. Inspired by the success of these programs, we propose GitHub-OSS Fixit, a team-based course project where students are taught to contribute to open-source Java projects by fixing bugs reported in GitHub. We described our course outline to teach students SE concepts by encouraging the usages of several automated program analysis tools. We also included the carefully designed instructions that we gave to students for participating in GitHub-OSS Fixit. As all lectures and labs are conducted online, we think that our course design could help in guiding future online SE courses. Overall, our survey results show that students think that GitHub-OSS Fixit could help them to improve many skills and apply the knowledge taught in class. In total, 154 students have submitted 214 pull requests to 24 different Java projects, in which 93 of them have been merged, and 46 have been closed by developers.","2021","2025-04-08 17:25:10","2025-04-08 17:25:10","","1–10","","","","","","","ICSE-JSEET '21","","","","IEEE Press","","","","","","","","","Place: Virtual Event, Spain","","","","software engineering; open-source software; program repair","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the last four years, the HFOSS Project has received material support from several partners, including the National Science Foundation, Accenture, Google, and Mozilla. This support has enabled the Project to expand its reach to add new college and university partners and to add more humanitarian software projects. Contributions to the HFOSS Project come from professionals in academia, IT organizations, and non-profit organizations that engage undergraduate students in courses, research projects, and summer internship experiences. Its curriculum is accessible to a wide range of undergraduates, since it includes courses for non- majors as well as computer science and engineering majors.

While code reviews are a common measure to catch bugs during development, they lack scalability, are error-prone, and time-consuming [2, 38, 41]. Thus, static analysis tools like Semgrep emerged to provide programmatic feedback on code. But static analyses often show low precision, which can jeopardize utility.In this case study, we investigate precision rates for Semgrep OSS for common web weaknesses from the OWASP Top 10 [35]. We explore method and tool limitations in weakness detection, OWASP classes, and Semgrep’s public PHP rule set. We apply the latter to 300 open source applications, invest 34 h in manual sample validation, and derive precision rates for each OWASP class.Our validation shows that the rules correctly detected weaknesses for seven OWASP classes with 86% precision, demonstrating the tool’s utility. Yet, we estimate that most findings are not exploitable (81%). Thus, there is still considerable assessment overhead for users. Our work further highlights that only a subset of weaknesses are detectable, as dimensions such as runtime context and insecure design remain hidden. Finally, we advise practitioners to not exclusively rely on public rules, as translating application-specific business logic and design choices may open up to the detection of previously uncovered weaknesses.","2024","2025-04-08 17:25:10","2025-04-08 17:25:10","","64–83","","","","","","","","","","","Springer-Verlag","Berlin, Heidelberg","","","","","","","","event-place: Lausanne, Switzerland","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given their importance, understanding the resilience of OSS projects is paramount. A primary reason for OSS project failure is the shock caused by the dropout of a core developer, which can jeopardize productivity and project survival. Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer. Our findings underscore the importance of a balanced approach in OSS project management, harmonizing productivity goals with resilience considerations.","2024","2025-04-08 17:25:10","2025-04-08 17:25:10","","706–709","","","","","","","WWW '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Singapore, Singapore","","","","causal inference; resilience; online collaboration networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results indicate that real networks are mainly characterized by the modular small-world structure, which is inherently correlated with the sub-project participation of developers. Most module members are single-dimensional developers whose coding-collaboration focuses on a small number of sub-projects (called the main dimension of the module), while a small proportion of module members are multi-dimensional developers who conduct coding-collaboration in the main dimension of different modules.

To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.","2021","2025-04-08 17:25:28","2025-04-08 17:52:59","","1020–1032","","","","","","","ICSE '21","","","","IEEE Press","","","","","","","","","Place: Madrid, Spain","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In addition, we present valuable ways in which this data has been and can be used.","2007","2025-04-08 17:25:28","2025-04-08 17:36:01","","26","","","","","","","MSR '07","","","","IEEE Computer Society","USA","","","","","","","","","","/Users/mgone/Zotero/storage/MZMCLSRT/Bird et al. - 2007 - Detecting Patch Submission and Acceptance in OSS P.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Continuous awareness of the product release status is required. Release readiness is a time-dependent attribute of the status of the product release, which aggregates the degree of satisfaction of a portfolio of release process and product measures.Goal: At different stages of a release cycle, the goal is to understand frequencies and pattern of occurrence of factors affecting project success by restricting the status of release readiness (called bottlenecks).Method: As a form of explorative case study research, we analyzed ten open source software (OSS) projects taken from the GitHub repository. As a retrospective study covering a period of 28 weeks, we monitored eight release readiness attributes and identified their impact on release readiness over time across the ten projects.Results: Feature completion rate, Bug fixing rate, and Features implemented were observed as the most frequent bottlenecks. The most frequent transition between bottlenecks is from Pull-request completion rate to Bug fixing rate. With the exception of Pull-request completion rate, no significant differences were found in occurrence of bottleneck factors between early and late stage of the release cycle.Conclusions: We received an initial understanding of the most frequent bottleneck factors for release readiness and their likelihood of subsequent occurrence. This is intended to guide the effort spent on improving release engineering.","2014","2025-04-08 17:25:28","2025-04-08 17:25:28","","","","","","","","","ESEM '14","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Torino, Italy","","/Users/mgone/Zotero/storage/59F8VSI3/Al Alam et al. - 2014 - Monitoring bottlenecks in achieving release readin.pdf","","release readiness; bottleneck identification; exploratory case study; retrospective analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, using LIWC dimensions that are correlated with the big five personality traits, we assess the personality of four top developers against a baseline for the entire mailing list. The two developers that were responsible for the major Apache releases had similar personalities. Their personalities were different from the baseline and the other developers. Second, the first and last 50 emails for two top developers who have left the project are examined. The analysis shows promise in understanding why developers join and leave a project.

But many OSS projects do not become sustainable, resulting in abandonment and even risks for the world's digital infrastructure. Prior work has looked at the reasons for this mainly from two very different perspectives. In software engineering, the focus has been on understanding success and sustainability from the socio-technical perspective: the OSS programmers' day-to-day activities and the artifacts they create. In institutional analysis, on the other hand, emphasis has been on institutional designs (e.g., policies, rules, and norms) that structure project governance. Even though each is necessary for a comprehensive understanding of OSS projects, the connection and interaction between the two approaches have been barely explored.In this paper, we make the first effort toward understanding OSS project sustainability using a dual-view analysis, by combining institutional analysis with socio-technical systems analysis. In particular, we (i) use linguistic approaches to extract institutional rules and norms from OSS contributors' communications to represent the evolution of their governance systems, and (ii) construct socio-technical networks based on longitudinal collaboration records to represent each project's organizational structure. We combined the two methods and applied them to a dataset of developer digital traces from 253 nascent OSS projects within the Apache Software Foundation (ASF) incubator. We find that the socio-technical and institutional features relate to each other, and provide complimentary views into the progress of the ASF's OSS projects. Refining these combined analyses can help provide a more precise understanding of the synchronization between the evolution of institutional governance and organizational structure.","2022-11","2025-04-08 17:25:45","2025-04-17 15:38:01","","","","CSCW2","6","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","/Users/mgone/Zotero/storage/XG5WVGUM/Yin et al. - 2022 - Open Source Software Sustainability Combining Ins.pdf","","institutional design; OSS sustainability; socio-technical systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We report findings from an interview-based study with contributors and maintainers working in a wide range of F/OSS projects. Maintainers of F/OSS projects do not just maintain software code in a more traditional software engineering understanding of the term: fixing bugs, patching security vulnerabilities, and updating dependencies. F/OSS maintainers also perform complex and often-invisible interpersonal and organizational work to keep their projects operating as active communities of users and contributors. We particularly focus on how this labor of maintaining and sustaining changes as projects and their software grow and scale across many dimensions.

Comput.","","","10.1145/3290837","https://doi.org/10.1145/3290837","Participation by product users is critical to success in free, open-source software (FOSS) software communities as they originate and develop valuable ideas for product innovation that are unlikely to originate from the core software development community. Users tend to be involved at the periphery of FOSS communities, suggesting new product ideas, highlighting problems with user documentation, or explaining when the product design fails to fit with the needs of their local user application domain. As an increasing number of FOSS projects employ a hybrid participation model that combines volunteer effort with paid software development effort or product support, it can be difficult for non-developer users to participate in product innovation. In colocated organizations, it is theorized that peripheral participants learn how to engage with the practices and cultural identity of a community through a sociocultural apprenticeship known as legitimate peripheral participation. But we have little literature that explores how legitimate peripheral participation is enabled in online communities.The research study presented in this article explores how participation by peripheral users in a hybrid FOSS project is afforded by participation architecture channels and community mechanisms that mediate two forms of engagement: a “cognitive apprenticeship” that introduces participants to situated domain activity, such as the community processes involved in product innovation, and a “social apprenticeship” by which participants become enculturated in the system of meanings, values, norms, and behaviors that govern community/participant identity. We identified five stages of community innovation, analyzing sociotechnical affordances of the online participation architecture that enable peripheral participants to internalize the meanings of community practice and to develop a social identity within the FOSS community. Our contribution to theory is provided by the substantive explanation of the cognitive and social translations that enable legitimate peripheral participation in online communities, mediated by sociotechnical access channels and mechanisms that afford two contrasting forms of opportunities for action: those resulting from interactions between a goal-oriented actor and the technology platform features or channels of participation, and those associated with the social structures, roles, and relationships underpinning community interactions. Neither of these is sufficient without the other. Our contribution to practice is provided by an explanation of how four distinct categories of affordance provide these cognitive and social apprenticeship benefits, allowing participation architecture designers to cater to all forms of peripheral user participation. We conclude that the technical affordances of a typical FOSS community participation architecture are insufficient to mediate peripheral participation by nontechnical users. Meaningful participation is mediated by interactions between boundary spanners who play knowledge-brokering and organizational bridging roles. The combination of technical and social affordances enables peripheral participants to acquire an interior view of community practices and social culture and in turn to introduce new ideas, new values, and new rationales to produce a generative dance of innovation that percolates through the community.","2018-12","2025-04-08 17:25:45","2025-04-08 17:25:45","","","","4","1","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","innovation; affordances; hybrid-FOSS community; Legitimate peripheral participation; participation architecture; user participation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given this characteristic, OSS communities have been studied as technical communities, where stakeholders join and evolve in their careers based on their (often voluntary) code contributions to the project. However, the OSS landscape is slowly changing with more people and companies getting involved in OSS. This means that projects now need people in non-technical roles and activities to keep the project sustainable and evolving. In this paper, we focus on understanding the roles and activities that are part of the current OSS landscape and the different career pathways in OSS. By conducting and analyzing 17 interviews with OSS contributors who are well known in the community, we provide empirical evidence of the existence and importance of community-centric roles (e.g advocate, license manager, community founder) in addition to the well-known project-centric ones (e.g maintainer, core member). However, the community-centric roles typically remain hidden, since these roles may not leave traces in software repositories typically analyzed by researchers. We found that people can build a career in OSS through different roles and activities, with different backgrounds, including those not related to writing software. Furthermore, people's career pathways are fluid, moving between project and community-centric roles. Our work highlights that communities and researchers need to take action to acknowledge the importance of these varied roles, making these roles visible and well-recognized, which can ultimately help attract and retain more people in the OSS projects.","2020-10","2025-04-08 17:25:45","2025-04-08 17:25:45","","","","CSCW2","4","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open-source; collaborative development; career; role","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

-"WV2N6X5X","journalArticle","","Balle, Andrea Raymundo; Oliveira, Mírian","Knowledge Sharing Profiles in Free Software Communities","","","","","","Knowledge is an obtainable, renewable, dynamic, context-dependent resource that is capable of providing competitive advantage in organizations. Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people’s intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.","","2025-04-14 17:38:53","2025-04-14 17:38:53","","","","","","","","","","","","","","","en","","","","","Zotero","","","","/Users/mgone/Zotero/storage/A2NTPWRP/Balle and Oliveira - Knowledge Sharing Profiles in Free Software Commun.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study’s empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project’s potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.","2009-05-01","2025-04-14 17:39:20","2025-04-14 17:40:12","2025-04-14 17:39:20","739-750","","5","82","","Journal of Systems and Software","","","","","","","","","","","","","ScienceDirect","","","","/Users/mgone/Zotero/storage/2S4P5X4A/Beecher et al. - 2009 - Identifying exogenous drivers and evolutionary sta.pdf; ; /Users/mgone/Zotero/storage/4HKCV5AG/S0164121208002409.html","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Systems+and+Software&rft.atitle=Identifying+exogenous+drivers+and+evolutionary+stages+in+FLOSS+projects&rft.au=Beecher%2C+Karl%3BCapiluppi%2C+Andrea%3BBoldyreff%2C+Cornelia.&rft.aulast=Beecher&rft.aufirst=Karl&rft.date=2009-05-01&rft.volume=82&rft.issue=5&rft.spage=739&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Systems+and+Software&rft.issn=01641212&rft_id=info:doi/","Open source software; Studies; Open-source software; Success; Project management; Open Source software; Software evolution; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Project; Software project management; Computers--Software; Floss; Object repository; Software repositories","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

Once software complexity is one of the most important attributes to determine software maintainability, controlling its level in the system evolution process makes the software easier to maintain, reducing the maintainability costs. Otherwise, uncontrolled complexity makes the maintenance and enhancement process lengthy, more costly and some times it can contribute to the system abandonment.

Where appropriate, our approach to scoping the field is contrasted with the procedures followed in systematic reviews. We emphasize how including a consultation exercise in this sort of study may enhance the results, making them more useful to policy makers, practitioners and service users.

We argue that while rightly stressing human agency they also create a false dichotomy between agential and environmental factors in the explanation.

However, there has been little focus on developing valid frameworks that enable critical evaluation and common understanding of factors influencing OSS adoption. This paper seeks to address this shortcoming by presenting a theory-grounded framework for exploring these factors and explaining their influence on OSS adoption, with the context of study being small- to medium-sized Information Technology (IT) businesses in the U.K. The framework has implications for this type of business - and, we will suggest, more widely - as a frame of reference for understanding, and as tool for evaluating benefits and challenges in, OSS adoption. It also offers researchers a structured way of investigating adoption issues and a base from which to develop models of OSS adoption. The study reported in this paper used the Decomposed Theory of Planned Behaviour (DTPB) as a basis for the research propositions, with the aim of: (i) developing a framework of empirical factors that influence OSS adoption; and (ii) appraising it through case study evaluation with 10 U.K. Small- to medium-sized enterprises in the IT sector. The demonstration of the capabilities of the framework suggests that it is able to provide a reliable explanation of the complex and subjective factors that influence attitudes, subjective norms and control over the use of OSS. The paper further argues that the DTPB proved useful in this research area and that it can provide a variety of situation-specific insights related to factors that influence the adoption of OSS.

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.

An expanded version of Gallivan's (2001) framework of contingent authority innovation describes the way new policies extended through the public structure of the country. Findings indicate that Venezuela's FLOSS migration process fuses the agendas of social inclusion, sovereignty, and freedom that the government is pursuing with the availability of a ""Free Libre"" technology. The present project specifically contributes to the literature that examines information and communication technology policies and their impact on developing countries. In addition, the theoretical expansion of Gallivan's framework can apply to other governmental technological adoptions where ideology and politics play critical roles.

Since software development is a creative task, the motivation of open source programmers can be compared to individuals in creative industries (Caves 2002). This paper summarizes the important trends in the research on motivation in open source and identifies variables that should be included in future research. Specifically, the current literature favors a taxonomy that considers two components of motivation--intrinsic (e.g., fun, flow, learning, community) and extrinsic (e.g., financial rewards, improving future job prospects, signaling quality). I make a case for incorporating both elements in developing an integrative theory about developer motivation. Three elements are identified as being unique to FLOSS development-diversity of project structures, co-existence of companies and communities and co-existence of creative and commercial elements. The important empirical evidence on FLOSS developer motivation is presented and analyzed. Four factors are identified as important mitigating and moderating factors in the conversation surrounding developer motivation- financial incentives, nature of task, group size and group structure. The role of these factors on developer motivation is discussed.[PUBLICATION ABSTRACT]","2006","2025-04-25 15:22:17","2025-04-25 15:22:17","","17-39","","4","18","","","","","","","","","","English","","","ABI/INFORM Global","840525397","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/rr87U?_a=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%3D%3D&_s=L%2FVcdfGFikGd87pIWhrmzIOnvy0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=On+the+intrinsic+and+extrinsic+motivation+of+free%2Flibre%2Fopen+source+%28FLOSS%29+developers&rft.au=Krishnamurthy%2C+Sandeep.&rft.aulast=Krishnamurthy&rft.aufirst=Sandeep&rft.date=2006-01-01&rft.volume=18&rft.issue=4&rft.spage=17&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-006-1002-x","Open source software; Sociology; Motivation; Open source; Open-source software; Software development; Developer; Creative industries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I suggest that the support for non-proprietary software (collectively FLOSS) allows developing countries to comply with their multi-lateral commitments and support the potential development of local software development. Because of the General Public License's dependence on copyright law, the deployment of FLOSS allows compliance with the Trade Related Aspects of Intellectual Property Rights (TRIPs) agreement, while at the same time facilitating the development of a local software 'community'.

One could argue that Free Software Foundation is using copyright to enforce their free software licenses as aggressively as the Business Software Alliance is enforcing its clients' copyrights. We will show that the reality is more complex and that there is a significant difference: the free software community uses primarily non-legal enforcement methods and trusts on social norms. We argue that free software could be used as a tool to make copyright more accepted in the less developed world because of its positive connection with copyright and community based approach. We explain why strong copyright is also in the interest of free software developers.

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and tribal knowledge that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 15:22:17","2025-04-25 15:22:17","","211-223","","2","28","","","","","","","","","","English","","","ABI/INFORM Global","521142269","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/qPQuT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzODA3NjIJNTIxMTQyMjY5Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTAvMDQvMDFyCjIwMTAvMDYvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=NwdJ61IfH0rCBSU3j8JRJOfAADI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+economy+of+free+and+open+source+software+in+the+preservation+of+digital+artefacts&rft.au=Morrissey%2C+Sheila.&rft.aulast=Morrissey&rft.aufirst=Sheila&rft.date=2010-04-01&rft.volume=28&rft.issue=2&rft.spage=211&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2F07378831011047622","Open source software; Studies; Open source; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Library And Information Sciences--Computer Applications; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, this expansion has also brought significant security challenges, particularly introducing and propagating software vulnerabilities. Despite the use of machine learning and formal methods to tackle these issues, there remains a notable gap in comprehensive surveys that summarize and analyze both Vulnerability Detection (VD) and Security Patch Detection (SPD) in OSS. This article seeks to bridge this gap through an extensive survey that evaluates 127 technical studies published between 2014 and 2023, structured around the Vulnerability-Patch lifecycle. We begin by delineating the six critical events that constitute the Vulnerability-Patch lifecycle, leading to an in-depth exploration of the Vulnerability-Patch ecosystem. We then systematically review the databases commonly used in VD and SPD, and analyze their characteristics. Subsequently, we examine existing VD methods, focusing on traditional and deep learning based approaches. Additionally, we organize current security patch identification methods by kernel type and discuss techniques for detecting the presence of security patches. Based on our comprehensive review, we identify open research questions and propose future research directions that merit further exploration.","2025-01","2025-04-25 15:22:17","2025-04-25 15:22:17","","1","","1","57","","","","","","","","","","English","","","ABI/INFORM Global","3156169971","","","Place: Baltimore Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=ACM+Computing+Surveys&rft.atitle=Vulnerabilities+and+Security+Patches+Detection+in+OSS%3A+A+Survey&rft.au=Lin%2C+Ruyan%3BFu%2C+Yulong%3BYi%2C+Wei%3BYang%2C+Jincheng%3BCao%2C+Jin%3BDong%2C+Zhiqiang%3BXie%2C+Fei%3BLi%2C+Hui.&rft.aulast=Lin&rft.aufirst=Ruyan&rft.date=2025-01-01&rft.volume=57&rft.issue=1&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=ACM+Computing+Surveys&rft.issn=03600300&rft_id=info:doi/10.1145%2F3694782","Open source software; Computers; Software reliability; Deep learning; Security; Machine learning; Formal method; Identification methods; Vulnerability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While these initiatives hold significant promise, they frequently encounter hurdles like poor productivity, leading to premature demise. This study explores activities that contribute to the long-term well-being of public-sector FOSS ecosystems, focusing on public-sector entities as orchestrators and keystone players. A qualitative multi-case study of three ecosystems was conducted, with data collected through interviews, participant observation, and analysis of online discussion forums. The study presents a model for health-sustaining activities in public-sector FOSS ecosystems. Orchestrators and keystone players are found to engage in health-sustaining activities through rulemaking, role creation, and tool provision, hinting at the explanatory potential of Activity Theory. Furthermore, the study identifies key challenges in orchestrating public sector FOSS ecosystems, such as institutional misalignment and conflicting policy frameworks, highlighting these as critical areas for future research.","2024","2025-04-25 15:22:17","2025-04-25 15:22:17","","","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","3152500844","","","Place: Aalborg Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/lP17b?_a=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%3D%3D&_s=puvyoHces6UrwrEs9hl2EOHFTb4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Scandinavian+Journal+of+Information+Systems&rft.atitle=Health+and+Orchestration+of+Public-Sector+Open-Source+Software+Ecosystems+Roles%2C+rules+and+tools&rft.au=Henttonen%2C+Katja+M%3BPulkkinen%2C+Mirja%3BTyrvainen%2C+Pasi.&rft.aulast=Henttonen&rft.aufirst=Katja&rft.date=2024-01-01&rft.volume=36&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Scandinavian+Journal+of+Information+Systems&rft.issn=09050167&rft_id=info:doi/","Open source software; governance; FOSS; Computers; Free software; open-source software; software ecosystem; Public domain; ecosystem health; Misalignment; orchestration; Players; public sector; Public sector; Qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine how projects engage in distinct ""discursive modulation practices"" to imprint the community's shared core doctrines and design principles onto the software thereby shaping its novelty and complexity. We borrow the concept of modulation from audio synthesis to explain how a preexisting signal-in our case, the ongoing community discourse-is modulated to produce varying sounds-in our case, the novelty and complexity of the software. The concept of modulation offers a lens to understand how emergent, community-wide development activities are influenced by filtering discursive positions and mixing those positions, thereby shaping the artifact's novelty and complexity. Our research shows that the modulation of novelty exhibits a range from ""proximal"" to ""distal"" searches for new features, while the modulation of complexity varies between ""integration"" and ""deprecation."" By drawing on these concepts, we formulate a theory that explains how modulation results in alternative OSS community approaches to shaping software novelty and complexity and how this process reflects and is reflected in the resulting software artifact.","2024-12","2025-04-25 15:22:17","2025-04-25 15:22:17","","1395","","4","48","","","","","","","","","","English","","","ABI/INFORM Global","3151242275","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Discursive+Modulation+in+Open+Source+Software%3A+How+Online+Communities+Shape+Novelty+and+Complexity&rft.au=Lindberg%2C+Aron%3BBerente%2C+Nicholas%3BHowison%2C+James%3BLyytinen%2C+Kalle.&rft.aulast=Lindberg&rft.aufirst=Aron&rft.date=2024-12-01&rft.volume=48&rft.issue=4&rft.spage=1395&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2023%2F16872","Open source software; Computers; Virtual communities; Software engineering; Social networks; Software development; Innovations; Hierarchies; Complexity; Artifacts; Collaborative learning; Modulation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 15:22:17","2025-04-25 15:22:17","","1449-1469","","4","63","","","","","","","","","","English","","","ABI/INFORM Global","3129871390","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Small+Business+Economics&rft.atitle=Financing+A+Free-for-All%3A+Crowdfunding+Open-Source+Software&rft.au=Bort%2C+James%3BMeoli%2C+Azzurra%3BSullivan%2C+David+W..&rft.aulast=Bort&rft.aufirst=James&rft.date=2024-12-01&rft.volume=63&rft.issue=4&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Small+Business+Economics&rft.issn=0921898X&rft_id=info:doi/10.1007%2Fs11187-023-00867-y","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business And Economics--Small Business; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Best practices suggest employing UX Capability Maturity Models (UXCMMs), which often specify an evolutionary plateau toward developing a UX-matured system and quantify organizational UX maturity into maturity levels ranging from no or ad hoc improvement to integrated continuous improvement. Numerous generically developed UXCMMs exist. However, none is created for the FOSS community, and less information is available to support their perfect match. Thus, raise suspicions if they have proper UX maturity influencing factors (UXMIFs) for the FOSS community or measure the right thing. The FOSS community differs from traditional software-developing communities and may have different dynamics and UXMIFs, necessitating unique and new methodologies for their discovery. This study, therefore, aims to identify the FOSS community’s UXMIFs and evaluate the community’s knowledge of UX maturity-related concepts. Its findings may help future researchers, practitioners, and other FOSS developers to develop UXCMMs exclusive to the FOSS community. The study’s design is both qualitative and quantitative. It adopted a systematic literature review, interviews, fuzzy Delphi Method, and thematic analysis to collect and analyze data and present the findings. The study’s sample included sixty-two active FOSS projects, fifteen FOSS stakeholders, and twelve UX experts. The outcome shows that 84% of UX experts agreed on the thirty-six FOSS’s UXMIFs with threshold d = 0.143 and crisp values greater than α-cut = 0.5. User feedback and adopted technologies were ranked first, while learnability and use speed were ranked last. Similarly, FOSS stakeholders have shown a shared understanding of UX maturity, connected concepts, and impacting factors.","2024-11","2025-04-25 15:22:17","2025-04-25 15:22:17","","7162-7178","","22","40","","","","","","","","","","English","","","ABI/INFORM Global","3128679414","","","Place: Norwood Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Human+-+Computer+Interaction&rft.atitle=The+Factors+Affecting+User+Experience+Maturity+in+Free+and+Open+Source+Software+Community%3A+An+Empirical+Study&rft.au=Namayala%2C+Phesto+P%3BKondo%2C+Tabu+S%3BMselle%2C+Leonard+J.&rft.aulast=Namayala&rft.aufirst=Phesto&rft.date=2024-11-01&rft.volume=40&rft.issue=22&rft.spage=7162&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Human+-+Computer+Interaction&rft.issn=10447318&rft_id=info:doi/10.1080%2F10447318.2023.2262270","Open source software; Interviews; Qualitative research; User experience; Literature reviews; Qualitative analysis; Best practice; Continuous improvement; Delphi method; free and open-source software; Fuzzy Delphi Method; maturity; Sociology--Computer Applications; UX maturity influencing factors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the security communities realize some limitations when they put most existing proposals into practice. The challenges are mainly concerned with (i) fine-grained unknown attack detection and (ii) ever-changing legitimate traffic adaptation. To tackle these problem, we present three key design norms. The core idea is to construct a model to split the data distribution hyperplane and leverage the concept of isolation, as well as advance the incremental model update. We utilize the isolation tree as the backbone to design our model, named FOSS, to echo back three norms. By analyzing the popular dataset of network intrusion traces, we show that FOSS significantly outperforms the state-of-the-art methods. Further, we perform an initial deployment of FOSS by working with the Internet Service Provider (ISP) to detect distributed denial of service (DDoS) attacks. With real-world tests and manual analysis, we demonstrate the effectiveness of FOSS to identify previously-unseen attacks in a fine-grained manner.","2024","2025-04-25 15:22:18","2025-04-25 15:22:18","","3945-3960","","5","32","","","","","","","","","","English","","","ABI/INFORM Global","3117135702","","","Place: New York Publisher: The Institute of Electrical and Electronics Engineers, Inc.

The path analysis and bootstrap samples revealed that customers who exhibit a high innate innovativeness and feel that they belong in the online community show a greater motivation towards platform exploration and participation in co-creation. Moreover, the effect of this synergic interaction on their co-creation participation was partially mediated by the normative dimension of their intrinsic motivation, while the hedonic dimension was not a strong predictor of co-creation contributions.

The study aims to assist a community of OSS developers in quantifying the product’s reliability. This research proposes reliability growth models for OSS by incorporating dynamicity in the debugging process. For this, stochastic differential equation-based analytical models are developed to represent the instantaneous rate of error generation. The fault introduction rate is modeled using exponential and Erlang distribution functions. The empirical applications of the proposed methodology are verified using the real-life failure data of the Open Source Software projects, GNU Network Object Model Environment, and Eclipse. A soft computing technique, Genetic Algorithm, is applied to estimate model parameters. Cross-validation is also performed to examine the forecasting efficacy of the model. The predictive power of the developed models is compared with various benchmark studies. The data analysis is conducted using the R statistical computing software. The results demonstrate the proposed models’ efficacy in parameter estimation and predictive performance. In addition, the optimal release time policy based on the proposed mathematical models is presented by formulating the optimization model that intends to minimize the total cost of software development under reliability constraints. The numerical illustration and sensitivity analysis exhibit the proposed problem's practical significance. The findings of the numerical analysis exemplify the proposed study's capability of decision-making under uncertainty.","2024-09","2025-04-25 15:22:18","2025-04-25 15:22:18","","531-569","","1","340","","","","","","","","","","English","","","ABI/INFORM Global","3098031040","","","Place: New York Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Annals+of+Operations+Research&rft.atitle=Stochastic+debugging+based+reliability+growth+models+for+Open+Source+Software+project&rft.au=Singhal%2C+Shakshi%3BKapur%2C+P.+K.%3BKumar%2C+Vivek%3BPanwar%2C+Saurabh.&rft.aulast=Singhal&rft.aufirst=Shakshi&rft.date=2024-09-01&rft.volume=340&rft.issue=1&rft.spage=531&rft.isbn=&rft.btitle=&rft.title=Annals+of+Operations+Research&rft.issn=02545330&rft_id=info:doi/10.1007%2Fs10479-023-05240-6","Open source software; Computers; Data analysis; Software reliability; Software development; Genetic algorithms; Public domain; Performance prediction; Industrial development; Cost analysis; Debugging; Differential equations; Distribution functions; Effectiveness; Error analysis; Growth models; Industry 4.0; Mathematical analysis; Numerical analysis; Optimization models; Parameter estimation; Parameter sensitivity; Probability distribution functions; Sensitivity analysis; Soft computing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In turn, specifying and evaluating OSS quality has become a significant challenge for OSS adoption in organizations that are inclined to use them. Although many OSS quality models have been proposed in the literature, the dynamic and diverse nature of OSS has caused these models to be heterogeneous in terms of structure and content. This has adversely affected the standardization of evaluations and led to the evaluation results obtained from different OSS quality models for the same purpose being incomparable and sometimes unreliable. Therefore, in this study, a meta-model for OSS quality (OSS-QMM), which employs a unified structure from existing quality models and enables the derivation of homogeneous models, has been proposed. For this purpose, a systematic and laborious effort has been spent via a step-based meta-model creation process including review-and-revise iterations. In order to validate the OSS-QMM, case study and expert opinion methods have been applied to answer three research questions (RQs) targeted to investigate practical applicability, results comparability, and effectiveness of using the meta-model. Multiple and embedded case study designs have been employed for evaluating three real ERP systems, and 20 subject matter experts have been interviewed during the validation process. The results of multi-faceted empirical studies have indicated that the OSS-QMM has addressed solving problems in OSS quality evaluation and its adoption with high degrees of confidence.","2024-06","2025-04-25 15:22:18","2025-04-25 15:22:18","","487-541","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","3070116394","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Quality+evaluation+meta-model+for+open-source+software%3A+multi-method+validation+study&rft.au=Y%C4%B1lmaz%2C+Nebi%3BTarhan%2C+Ay%C3%A7a+Koluk%C4%B1sa.&rft.aulast=Y%C4%B1lmaz&rft.aufirst=Nebi&rft.date=2024-06-01&rft.volume=32&rft.issue=2&rft.spage=487&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-023-09658-w","Open source software; Software; Case studies; Software quality; Enterprise resource planning; Public domain; Computers--Software; Quality assessment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Mostramos que una gestión sinérgica de la marca y la comunidad de desarrolladores – manteniendo un alto grado de control sobre ambas – puede permitir la explotación de sus complementariedades.","2024","2025-04-25 15:22:18","2025-04-25 15:22:18","","52-66","","1","28","","","","","","","","","","English","","","ABI/INFORM Global","3015030030","","","Place: Montréal Publisher: Management International","","; ","https://media.proquest.com/media/hms/PFT/1/LWlkX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=BuzVbQbhYSCwcSZJpONq7SIDfp0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+International&rft.atitle=Le+r%26ocirc%3Ble+de+la+marque+dans+le+business+model+des+%26eacute%3Bditeurs+de+logiciels+open+source%26nbsp%3B%3A+une+%26eacute%3Btude+de+cas&rft.au=Corbel%2C+Pascal%3BKadji+Ngassam%2C+Martial.&rft.aulast=Corbel&rft.aufirst=Pascal&rft.date=2024-01-01&rft.volume=28&rft.issue=1&rft.spage=52&rft.isbn=&rft.btitle=&rft.title=Management+International&rft.issn=12061697&rft_id=info:doi/10.59876%2Fa-bbwn-wasa","Open source software; Business And Economics--Management; Open source; Business model; appropriation; open-source software; Business models; Technological change; Innovations; apropiación; brand; business model; logiciel open source; marca; marque; modelo de negocio; software de código abierto","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article we investigate the structure and the coordination practices adopted by development teams during the bug-fixing process, which is considered one of main areas of FLOSS project success. In particular, based on a codification of the messages recorded in the bug tracking system of four projects, we identify the accomplished tasks, the adopted coordination mechanisms, and the role undertaken by both the FLOSS development team and the FLOSS community. We conclude with suggestions for further research.","2008","2025-04-25 15:22:18","2025-04-25 15:22:18","","1-30","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954644395","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/KG6YX?_a=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%3D%3D&_s=iDEkf1pug8ELx6vBEmykANluda0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Bug+Fixing+Practices+within+Free%2FLibre+Open+Source+Software+Development+Teams&rft.au=Crowston%2C+Kevin%3BScozzi%2C+Barbar.&rft.aulast=Crowston&rft.aufirst=Kevin&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040101","Open source software; Open source; Software; Open-source software; Coordination; Teams; Software development; Distributed computing; Computers--Data Base Management; Tracking systems; Bulletin boards; Codification; Fixing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS development takes online community as its organizational form, and developers voluntarily work for the project. In the project execution process, control aligns individual behaviors toward the organizational goals via the Internet and becomes critical to the success of OSS projects. This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community. The study contributes to a better understanding of OSS project organizations and processes, and provides advice for OSS development.","2011","2025-04-25 15:22:18","2025-04-25 15:40:34","","26-42","","1","22","","","","","","","","","","English","","","ABI/INFORM Global","2954642973","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/FF6YX?_a=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%3D%3D&_s=eR6mIJMXjWbAL%2Fsn%2Bk7epfAXKLA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=A+Study+of+Open+Source+Software+Development+from+Control+Perspective&rft.au=Lin%2C+Zhangxi%3BXu%2C+Bo%3BXu%2C+Yan.&rft.aulast=Lin&rft.aufirst=Zhangxi&rft.date=2011-01-01&rft.volume=22&rft.issue=1&rft.spage=26&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2011010102","Open source software; Open source; Software Development; Software; Open-source software; Software development; Control; Open Source Software (OSS); Software industry; Computers--Data Base Management; Industrial development; Open; OSS Development; Outcome; Project Management; Self-control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, using the GINI coefficient as a measure of inequality within the developer group.","2008","2025-04-25 15:22:18","2025-04-25 15:22:18","","31-57","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954642921","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/VE6YX?_a=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%3D%3D&_s=%2FKtwwtxNqxDUu%2FrbSm1WOFgxmxw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Exploring+the+Effects+of+Process+Characteristics+on+Products+Quality+in+Open+Source+Software+Development&rft.au=Koch%2C+Stefan%3BNeumann%2C+Christian.&rft.aulast=Koch&rft.aufirst=Stefan&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=31&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040102","Open source software; Open source; Software; Software development; Product design; Impact analysis; Public domain; Computers--Data Base Management; Source code; Gini coefficient; Repositories","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However (1) the adoption of BI tools remains relatively low (2) the acquisition costs of proprietary BI tools are relatively high and (3) the level of satisfaction with these BI tools remain low. Given the potential of open source BI (OSBI) tools, there is a need for analyzing barriers that prevent organizations from adopting OSBI. Drawing a systematic review and a Qualitative Survey of BI Experts, this study proposes a framework that categorizes and structures 23 barriers to OSBI adoption by organizations including 4 that were identified by BI Experts but not explicitly found in the literature.

In recent years, this phenomenon has increasingly manifested in virtual collaborative spaces such as open‐source software communities because of the advancement in the use of online technologies and the heightened need for distance work. However, it is still unclear which underlying mechanisms foster collaboration in these spaces. By using the Linux kernel open‐source software community as a case study, we analyze data from the linux‐pci@vger.kernel.org mailing list to model the influence of proximity on the likelihood of collaboration between individuals. Our dataset is composed of 10,513 message replies to the PCI mailing list posted by its 654 active members in the years 2013 to 2015. Our results show that geographical proximity does not have a direct impact on collaboration, while organizational features defined by institutional and organizational proximity do significantly affect collaboration.

In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace. Using stakeholder theory, we identified stakeholder groups within a single OSS project to demonstrate their distinct interests and how these interests influence their value creation activities over time. Collectively, these interests enable the project's long-term development.","2023","2025-04-25 15:22:18","2025-04-25 15:22:18","","3048-3078","","7","36","","","","","","","","","","English","","","ABI/INFORM Global","2919795922","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/yExBX?_a=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%3D%3D&_s=z0viFxlTm14pG0ZvB1tVTH8hCe4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=How+do+different+stakeholder+groups+within+an+open+source+software+project+influence+the+project%27s+development%3A+a+case+study+of+OpenSimulator&rft.au=Paul+Di+Gangi%3BTeigland%2C+Robin%3BYetis%2C+Zeynep.&rft.aulast=Paul+Di+Gangi&rft.aufirst=&rft.date=2023-10-01&rft.volume=36&rft.issue=7&rft.spage=3048&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-10-2021-0751","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Research; Success; Text analysis; Strategy; Case studies; Virtual community; Stakeholders; Software testing; Case study; Public domain; Investigations; Software project management; Entrepreneurs; Value creation; Value proposition; Library And Information Sciences--Computer Applications; Small & medium sized enterprises-SME; Academic staff; FLOSS (Open source software); Formal organization; Mailing lists; OpenSimulator; Stakeholder theory; Time use; Virtual world","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software maintenance is required to fix bugs, to add new features, to improve performance, and/or to adapt to a changed environment. In this article, we examine change in cognitive complexity and its impacts on maintenance in the context of open source software (OSS). Relationships of the change in cognitive complexity with the change in the number of reported bugs, time taken to fix the bugs, and contributions from new developers are examined and are all found to be statistically significant. In addition, several control variables, such as software size, age, development status, and programmer skills are included in the analyses. The results have strong implications for OSS project administrators; they must continually measure software complexity and be actively involved in managing it in order to have successful and sustainable OSS products.

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume – suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017","2025-04-25 15:22:19","2025-04-25 15:22:19","","43-66","","2","29","","","","","","","","","","English","","","ABI/INFORM Global","2866855510","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/wC7YX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=QS%2FEW1SXZDT0EEcTLA0f0RbsTzY%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+and+End+User+Computing&rft.atitle=Developers%2C+Quality+Control+and+Download+Volume+in+Open+Source+Software+%28OSS%29+Projects&rft.au=Hill%2C+Geoffrey%3BDatta%2C+Pratim%3BCandice+Vander+Weerdt.&rft.aulast=Hill&rft.aufirst=Geoffrey&rft.date=2017-04-01&rft.volume=29&rft.issue=2&rft.spage=43&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+and+End+User+Computing&rft.issn=15462234&rft_id=info:doi/10.4018%2FJOEUC.2017040103","Open source software; Open source; Software; Open-source software; Open Source Software; Quality control; Segmented Regression; Software development; Computers--Electronic Data Processing; Developer Limit; Downloading; Quality Control; Quality Control Index; Regression Discontinuity; Tragedy of the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standardization in OSS quality is of vital importance as a communication vehicle for stakeholders in identifying and selecting high-quality products. Thus, meta-models help to define a standardized language and enable to propose quality models that can be used to perform comparable measurements.ObjectiveConsidering the lack of a comprehensive meta-model of OSS quality in the literature, there appears a need to see a more complete picture of OSS quality and to represent its concepts more formally. Therefore, in this study, it is aimed to develop a solid base for a comprehensive meta-model of OSS quality to create a common understanding among stakeholders.MethodA systematic way has been followed toward developing a common structure, defining a consistent terminology and, finally, providing a meta-model of OSS quality. In this context, (1) the common structure of the quality models for OSS has been investigated, (2) the terms of the general-purpose meta-models of software quality have been analyzed based on the international standards, and (3) the terms of the quality models for OSS have been mapped with the elements of these meta-models.ResultsAn initial meta-model of OSS quality, which employs a unified structure from the OSS quality models and eliminates the inconsistencies determined in the general-purpose meta-models of software quality, has been proposed and an implementation of this meta-model has been demonstrated.ConclusionThis initial meta-model of OSS quality with a standard terminology can be taken as a guide by researchers who will propose or revise their OSS quality models. It will allow developing multiple OSS quality models with homogenous structure and terms, and also enable comparing the evaluation results obtained by these models.","2023-09","2025-04-25 15:22:19","2025-04-25 15:22:19","","721-773","","3","31","","","","","","","","","","English","","","ABI/INFORM Global","2859386662","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/v6eiU?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyOTEwNjIKMjg1OTM4NjY2MjoNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDIzLzA5LzAxcgoyMDIzLzA5LzMwegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAg9BcnRpY2xlfEZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=wb6Jpkyf0TWqIBbsCGHf2Lyhalk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Matching+terms+of+quality+models+and+meta-models%3A+toward+a+unified+meta-model+of+OSS+quality&rft.au=Y%C4%B1lmaz%2C+Nebi%3BTarhan%2C+Ay%C3%A7a+Koluk%C4%B1sa.&rft.aulast=Y%C4%B1lmaz&rft.aufirst=Nebi&rft.date=2023-09-01&rft.volume=31&rft.issue=3&rft.spage=721&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-022-09603-3","Open source software; OSS; Software; Open-source software; Context; Software quality; Terminology; Standardization; Computers--Software; Meta-model; Metamodeling; Quality evaluation; Quality measurement; Quality metrics; Quality model; Quality standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The model is extracted to support source code reusing and revising as the two primary targets of OSS through a systematic review of related documents.Design/methodology/approachConducting a systematic review, all the software reusing criteria are identified and introduced to the web of data by an ontology for OSS (O4OSS). The software semantic model introduced in this paper explores OSS through triple expressions in which the O4OSS properties are predicates.FindingsThis model improves the quality of web data by describing software in a structured machine–human readable profile, which is linked to the related data that was previously published on the web. Evaluating the OSS semantic model is accomplished through comparing it with previous approaches, comparing the software structured metadata with profile index of software in some well-known repositories, calculating the software retrieval rank and surveying domain experts.Originality/valueConsidering context-specific information and authority levels, the proposed software model would be applicable to any open and close software. Using this model to publish software provides an infrastructure of connected meaningful data and helps developers overcome some specific challenges. By navigating software data, many questions which can be answered only through reading multiple documents can be automatically responded on the web of data.","2023","2025-04-25 15:22:19","2025-04-25 15:38:42","","685-707","","4","75","","","","","","","","","","English","","","ABI/INFORM Global","2830442491","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/vsAXS?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=MSd3SwkOlhi0fHhVlE4D7wu73Ro%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Aslib+Journal+of+Information+Management&rft.atitle=A+semantic+model+to+publish+open+source+software+on+the+web+of+data&rft.au=Mosharraf%2C+Maedeh.&rft.aulast=Mosharraf&rft.aufirst=Maedeh&rft.date=2023-07-01&rft.volume=75&rft.issue=4&rft.spage=685&rft.isbn=&rft.btitle=&rft.title=Aslib+Journal+of+Information+Management&rft.issn=20503806&rft_id=info:doi/10.1108%2FAJIM-09-2021-0280","Open source software; Library And Information Sciences; Collaboration; Open source; Software; Open-source software; Software packages; Metadata; Natural language; Semantics; Open data; Software development; Systematic review; Public domain; Source code; Documents; Linked data; Linked Data; Moodle; Ontology; Publishing; Semantic model; Semantic web; Software model; Web of data","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A prime example for this phenomenon is open source software (OSS) development, where multiple actors contribute to a public good, which is also integrated into company-owned software products. Despite the importance of aligning community work on the public good with own in-house development efforts, firms have limited options to directly control the OSS project or the project's outcome. This research reflects on resource deployment control, a control mode in which firms assign own developers to work for an OSS project to influence the OSS project, and tests hypotheses on individual developer levels.Design/methodology/approachThis research tests the effect of perceived resource deployment control on opinion leadership by analyzing employed Linux kernel developers.FindingsThe findings show that developers who perceive being assigned to an OSS project to enact control also exhibit opinion leadership. This research also investigates boundary conditions such as the OSS business model a firm operates and the reputation developers assign to the developers' employer.Originality/valueThis research is the first that is devoted to resource deployment control, and the research closes with a discussion of implications for control theory and the management of innovation beyond firm boundaries.","2023","2025-04-25 15:22:19","2025-04-25 15:22:19","","1645-1668","","4","36","","","","","","","","","","English","","","ABI/INFORM Global","2808164080","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/FztSR?_a=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%3D%3D&_s=Zh%2B34DtfoD4Yld7S8M4N0fMj1oE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=Innovating+beyond+firm+boundaries%3A+resource+deployment+control+in+open+source+software+development&rft.au=Schaarschmidt%2C+Mario.&rft.aulast=Schaarschmidt&rft.aufirst=Mario&rft.date=2023-05-20&rft.volume=36&rft.issue=4&rft.spage=1645&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-08-2021-0624","Open source software; Innovation; Leadership; Information systems; Boundaries; Information technology; Collaboration; Open source; Open-source software; Linux; Companies; Intellectual property; Software development; Business models; Control theory; Public domain; Systems development; Innovations; Research & development--R&D; Employees; Library And Information Sciences--Computer Applications; Assignment; Boundary conditions; Community work; Deployment; Developer survey; Open source business model; Opinion leadership; Perceived control; Resource deployment control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks.Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.Originality/value This study is the first attempt to consider the network metrics in both module networks of the technical sub-system and developer networks of the social sub-system to better understand their influences on project success.","2023","2025-04-25 15:22:19","2025-04-25 15:22:19","","895-915","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","2787783369","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/HROxQ?_a=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%3D%3D&_s=K%2FslBwH0OOutLsUnP1mOAPTsYXY%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=Social-technical+network+effects+in+open+source+software+communities%3A+understanding+the+impacts+of%26nbsp%3Bdependency+networks+on%26nbsp%3Bproject+success&rft.au=Wu%2C+Jiang%3BHuang%2C+Xiao%3BWang%2C+Bin.&rft.aulast=Wu&rft.aufirst=Jiang&rft.date=2023-02-15&rft.volume=36&rft.issue=2&rft.spage=895&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-09-2021-0684","Design; Open source software; Social network analysis; Information technology; Collaboration; Open source; Software engineering; Software; Computer architecture; Software reliability; Research; Success; Teams; Social networks; Software development; Software quality; Public domain; Investigations; Project Success; Network effect; Social network; Library And Information Sciences--Computer Applications; Dependency; Closeness; Dependency network; Dependency networks; Modules; Open source software community; Social-technical system","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software.Design/methodology/approach>A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76%.Findings>The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff.Research limitations/implications>This study is geographically limited to the university libraries in Islamabad.Practical implications>This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries.Originality/value>This study concludes that the development of IRs in university libraries is a need of the hour. Although the launching of IRs requires certain skills and competencies, Pakistani librarians can overcome these challenges by mastering the ICT skills.","2023","2025-04-25 15:22:19","2025-04-25 15:22:19","","47-55","","1","51","","","","","","","","","","English","","","ABI/INFORM Global","2761066259","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/qXtPQ?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=q97LwmwamKrUnhQo4p8fi9qVmUI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Discovery+and+Delivery&rft.atitle=Open+source+software+adoption+for+development+of+institutional+repositories+in+university+libraries+of+Islamabad&rft.au=Muhammad+Kabir+Khan%3BArslan+Sheikh.&rft.aulast=Muhammad+Kabir+Khan&rft.aufirst=&rft.date=2023-01-01&rft.volume=51&rft.issue=1&rft.spage=47&rft.isbn=&rft.btitle=&rft.title=Information+Discovery+and+Delivery&rft.issn=23986247&rft_id=info:doi/10.1108%2FIDD-10-2021-0113","Open source software; Library And Information Sciences; Open source; Open-source software; Dissertations & theses; 51921:Libraries and Archives; Digital libraries; Digital preservation; Academic libraries; Digital library; Digital library system; Free softwares; Institutional repositories; Institutional repository; Islamabad Pakistan; Librarians’ challenges; Librarians’ perceptions; Library; Library science; Pakistan; Repository","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper analyzes the governance of these organizations from the perspective of their structure and control, considering the development trajectory of three community-based free software projects in Brazil. Results show that the constant need to produce modern technologies gives rise to external pressures that promote change - albeit temporary - in the governance of these projects, making them resemble a cathedral more than a bazaar. Governance does not follow a cycle of sequential improvement; it changes depending on the external organizational actors present, such as sponsors. This suggests the need for strategic and flexible governance to deal with the acquisition and allocation of organizational resources. Governance of the projects described here varies along a spectrum of (in)formality that allows both production models - cathedral or bazaar - to exist in the same organization at different periods.","2022-02","2025-04-25 15:22:20","2025-04-25 15:22:20","","1-17","","1","62","","","","","","","","","","English","","","ABI/INFORM Global","2623909517","","","Place: São Paulo Publisher: Fundação Getulio Vargas","","; ","https://media.proquest.com/media/hms/PFT/1/jxy7M?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgYxMDU3ODkyCjI2MjM5MDk1MTc6DURvY3VtZW50SW1hZ2VCATBSBk9ubGluZVoCRlRiA1BGVGoKMjAyMi8wMS8wMXIKMjAyMi8wMi8yOHoAggElUC0xMDAwMDAxLTEyODYxLUNVU1RPTUVSLW51bGwtMTE0NDQwMpIBBk9ubGluZcoBVE1vemlsbGEvNS4wIChNYWNpbnRvc2g7IEludGVsIE1hYyBPUyBYIDEwLjE1OyBydjoxMzUuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC8xMzUuMNIBElNjaG9sYXJseSBKb3VybmFsc5oCB1ByZVBhaWSqAitPUzpFTVMtTWVkaWFMaW5rc1NlcnZpY2UtZ2V0TWVkaWFVcmxGb3JJdGVtygIPQXJ0aWNsZXxGZWF0dXJl0gIBWfICAPoCAVmCAwNXZWKKAxxDSUQ6MjAyNTAyMjcwMjA0MDc2MTM6NjY5NzMy&_s=BGaGruidEWusyM75C8u5eUdG78o%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revista+de+Administra%C3%A7%C3%A3o+de+Empresas&rft.atitle=TRANSFORMATION+OF+FREE+AND+OPEN+SOURCE+SOFTWARE+DEVELOPMENT+PROJECTS%3A+GOVERNANCE+BETWEEN+THE+CATHEDRAL+AND+BAZAAR&rft.au=Ferraz%2C+Isabela+Neves%3BDos+Santos%2C+Carlos+Denner.&rft.aulast=Ferraz&rft.aufirst=Isabela&rft.date=2022-01-01&rft.volume=62&rft.issue=1&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Revista+de+Administra%C3%A7%C3%A3o+de+Empresas&rft.issn=00347590&rft_id=info:doi/10.1590%2FS0034-759020220104","Open source software; Business And Economics--Management; Virtual communities; Open source; Transformation; Governance; Software development; Freeware; Resource allocation; Bureaucracy; Development programs","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022-01","2025-04-25 15:22:20","2025-04-25 15:37:51","","165-195","","1","23","","","","","","","","","","English","","","ABI/INFORM Global","2619733915","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/Ydh4M?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=I9YhzKEzKqnQYd%2FlycaVgvqO4Cc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=A+Motivation-Hygiene+Model+of+Open+Source+Software+Code+Contribution+and+Growth&rft.au=Sharma%2C+Pratyush+Nidhi%3BDaniel%2C+Sherae+L%3BTingting+%28Rachel%29+Chung%3BGrover%2C+Varun.&rft.aulast=Sharma&rft.aufirst=Pratyush&rft.date=2022-01-01&rft.volume=23&rft.issue=1&rft.spage=165&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00712","Open source software; Motivation; Information systems; Growth; Open source; Software; Open-source software; Computers--Information Science And Information Theory; Public domain; Source code; Growth models; A Motivation-Hygiene Model of Open Source Software Code Contribution and Growth; Computer program; Hygiene","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 15:22:20","2025-04-25 15:22:20","","8","","","49","","","","","","","","","","English","","","ABI/INFORM Global","2582094786","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/x0MyK?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNjQyNTIKMjU4MjA5NDc4NjoNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDIxLzAxLzAxcgoyMDIxLzEyLzMxegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAg9BcnRpY2xlfEZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=uaAEFLA0RlKKUmWt5wvgE5szUa4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Episodic+Peripheral+Contributors+and+Technical+Dependencies+in+Open+Source+Software+%28OSS%29+Ecosystems&rft.au=Moon%2C+Eunyoung.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2021-01-01&rft.volume=49&rft.issue=&rft.spage=8&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04908","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Choice process episodes were selected as the unit of analysis and were coded for the task trigger and topic. The impact of these factors on participation (i.e. the numbers of participants and messages) was assessed by regression.FindingsThe results reveal differences in participation related to different task triggers and task topics. Further, the results suggest the mediating role of the number of participants in the relationships between task characteristics and the number of messages. The authors also speculate that project type serves as a boundary condition restricting the impacts of task characteristics on the number of participants and propose this relationship for future research.Research limitations/implicationsEmpirical support was provided to the important effects of different task characteristics on individual participation behaviors in FLOSS development tasks.Practical implicationsThe findings can help FLOSS participants understand participation patterns in different tasks and choose the types of tasks to attend to.Originality/valueThis research explores the impact of task characteristics on participation in FLOSS development at the task level, while prior research on participation in FLOSS development has focused mainly on factors at the individual and/or project levels.","2021","2025-04-25 15:22:20","2025-04-25 15:22:20","","1177-1202","","4","31","","","","","","","","","","English","","","ABI/INFORM Global","2550176960","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/TmssJ?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=H5D3nvUhF2oBsTBAEDsGKUrVvmM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Internet+Research&rft.atitle=Participation+in+community-based+free%2Flibre+open+source+software+development+tasks%3A+the+impact+of+task+characteristics&rft.au=Kangning+Wei%3BCrowston%2C+Kevin%3BEseryel%2C+U+Yeliz.&rft.aulast=Kangning+Wei&rft.aufirst=&rft.date=2021-01-01&rft.volume=31&rft.issue=4&rft.spage=1177&rft.isbn=&rft.btitle=&rft.title=Internet+Research&rft.issn=10662243&rft_id=info:doi/10.1108%2FINTR-03-2020-0112","Open source software; Behavior; Social interaction; Computers--Internet; Open source; Participation; Electronic mail; Open-source software; Coordination; Research; Free/libre open source software (FLOSS); Teams; Messages; Software development; Crowdsourcing; Public domain; Freeware; Empirical analysis; Computer Software; Free and open-source software; Community Relations; Boundary conditions; Community participation; Interpersonal Relationship; Leadership Effectiveness; Longitudinal Studies; Task characteristics; Work Environment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So it was important to reassess the factors enabling OSS adoption in order to enhance OSS utilization within public sector organisations. This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-25 15:22:20","2025-04-25 15:22:20","","","","2","17","","","","","","","","","","English","","","ABI/INFORM Global","2546081220","","","Place: Wollongong Publisher: Australasian Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/na1qJ?_a=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&_s=xNWN%2FZf9JyIZADy5hXjgvNRqXn0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Australasian+Journal+of+Information+Systems&rft.atitle=Enablers+of+Open+Source+Software+adoption%3A+A+case+study+of+APS+organisations&rft.au=Gurusamy%2C+Kavitha%3BCampbell%2C+John.&rft.aulast=Gurusamy&rft.aufirst=Kavitha&rft.date=2012-01-01&rft.volume=17&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Australasian+Journal+of+Information+Systems&rft.issn=14498618&rft_id=info:doi/10.3127%2Fajis.v17i2.731","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Computers--Computer Systems; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The exploratory research was a preliminary contact with the investigated field to make the arguments presented more reliable. Among the reflections, it is observed that even though it is possible to distinguish community-based free software projects from traditional organizations, a crucial factor not always considered are the transformations resulting from the development of these projects.

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 15:22:20","2025-04-25 15:22:20","","20","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2500501225","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/JGBVI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=TumiZGundAt%2FGKwb2yVCFBQfkxQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Decision-making+Processes+in+Community-based+Free%2FLibre+Open+Source+Software-development+Teams+with+Internal+Governance%3A+An+Extension+to+Decision-making+Theory&rft.au=Eseryel%2C+U+Yeliz%3BKangning+Wei%3BCrowston%2C+Kevin.&rft.aulast=Eseryel&rft.aufirst=U&rft.date=2020-01-01&rft.volume=46&rft.issue=&rft.spage=20&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04620","Open source software; Decision making; Computers--Information Science And Information Theory; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.

Special emphasis is placed on the legal ramifications of this alternative approach to business software development and a long, complex lawsuit that threatens to restructure the open source philosophy. It is not surprising that commercial software companies have attacked Linux and other open source software packages. A legal attack from a company called SCO could jeopardize the future of open source software, with users and potential users of open source software fearful of previously unasserted intellectual property lawsuits. On Mar 6, 2003, the SCO Group initiated a civil lawsuit again IBM, claiming damages that were later increased to $5 billion. The possibility that SCO could have some proprietary claim to Linux is negated by the free software community's willingness to rewrite any offending code. At this time, there is little reason for organizations using Linux and other open source programs to fear the results of the SCO litigation.","2006-08","2025-04-25 15:22:20","2025-04-25 15:22:20","","5-9","","3","15","","","","","","","","","","English","","","ABI/INFORM Global","229508326","","","Place: New York Publisher: Taylor & Francis Ltd.","","; ","https://media.proquest.com/media/hms/OBJ/LlDET?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU1MjQzMzIJMjI5NTA4MzI2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDcvMDFyCjIwMDYvMDgvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=zj9yCFENJ0rmQFajcsF%2Brl076qI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Security&rft.atitle=Open+Source+Software+and+the+SCO+Litigation&rft.au=Freeman%2C+Edward+H.&rft.aulast=Freeman&rft.aufirst=Edward&rft.date=2006-07-01&rft.volume=15&rft.issue=3&rft.spage=5&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Security&rft.issn=1065898X&rft_id=info:doi/","Open source software; Computers; Open source; Computer science; Open-source software; Linux; Operating systems; Intellectual property; Software development; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; United States--US; 9190:United States; Books; Personal computers; Litigation; 4330:Litigation; Computers--Computer Security; Damage claims; Lawsuit","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The open-source movement's unique development practices are challenging the traditional views of how innovation should work. Some people suggest open-source software developers freely reveal and share because they garner personal benefits from doing so, such as learning to develop complex software. Open-source projects can be started by anyone with the appropriate programming skills and motives. In the future, some managers may encourage the use of open-source software in their own firms. Others may attempt to build a business based on distributing and servicing open-source software. The open-source software movement also provides important management lessons regarding the most effective ways to structure and implement innovation. The lessons of open-source projects demonstrate the value of specialization through self-selection and how norms of meritocracy and peer recognition help ensure product quality.","2003","2025-04-25 15:22:20","2025-04-25 15:22:20","","14-18","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","224965356","","","Place: Cambridge Publisher: Massachusetts Institute of Technology, Cambridge, MA","","; ","https://media.proquest.com/media/hms/OBJ/cGueT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNjE0MjIJMjI0OTY1MzU2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDMvMDQvMDFyCjIwMDMvMDYvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=J%2FZUXiYkA9J3hvZ6bxOviM2uR3Q%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIT+Sloan+Management+Review&rft.atitle=Open-source+software+development&rft.au=Georg+von+Krogh.&rft.aulast=Georg+von+Krogh&rft.aufirst=&rft.date=2003-04-01&rft.volume=44&rft.issue=3&rft.spage=14&rft.isbn=&rft.btitle=&rft.title=MIT+Sloan+Management+Review&rft.issn=15329194&rft_id=info:doi/","Open source software; Innovation; Business And Economics--Management; Open source; Software; Open-source software; Licenses; Product development; Trends; Internet; Software development; Meritocracy; 5240:Software & systems; Public domain; Freeware; Developer; Innovations; United States--US; 9190:United States; Defense contracts; Laboratories; Organization studies; Open; Programmer; Public good; Computer programming; Projects; Self-selection bias; User needs","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper reviews relevant literature related to international operations of knowledge-intensive firms, especially in the software industry. Theoretical development is based here on a combination of the network approach, international new venture theory and inward-outward internationalization. The findings in this study suggest that the international activities of OSS firms can be divided into project activities and business activities. Project activities include inward and outward linkages, and partner identification. Business activities include domestic and partner network activities that can lead to international business as well. For scholars, the framework provides a new approach to explain many international activities of OSS firms by integrating three international business theories. In addition, it provides good starting point for further empirical examination. The framework helps managers gain a better understanding of complex circumstances embedded into the international activities of OSS firms. With that better understanding, the managers can focus their activities, which helps further to improve their firms' competitiveness engendered by the international activities in the OSS development. The framework developed in this study is believed to be the first serious attempt to provide a deeper theoretical understanding of international activities of OSS firms.

Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied - especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 15:22:21","2025-04-25 15:22:21","","227-238","","2","44","","","","","","","","","","English","","","ABI/INFORM Global","222420968","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/ORIG/5/G0cEE?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzNTA3MjIJMjIyNDIwOTY4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDUvMDEvMDFyCjIwMDUvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=YMjkzlzFjF9WOvmW0OmRjMMrL1E%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Systems+Journal&rft.atitle=The+value+of+open+standards+and+open-source+software+in+government+environments&rft.au=Simon%2C+K+D.&rft.aulast=Simon&rft.aufirst=K&rft.date=2005-04-01&rft.volume=44&rft.issue=2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=IBM+Systems+Journal&rft.issn=00188670&rft_id=info:doi/","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Evidence shows that OSS fails in many cases to displace dominant market leaders even in the case of user's unhappiness with the prevalent solution, while in some others OSS is adopted without a clear advantage. Using a qualitative research approach, we highlight the existence of a new context, in which the adoption of Linux-based OSS platforms by companies is not led only by traditional drivers. User communities and broader social responsibility considerations have been found to exert some degrees of pressure on the IT decision maker. Through the analysis of some significant cases we propose a framework that helps to depict under which conditions significant OSS adoption may unfold.","2006-03","2025-04-25 15:22:21","2025-04-25 15:22:21","","85-103","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","222358351","","","Place: Paris Publisher: Editions ESKA","","; ","https://media.proquest.com/media/hms/OBJ/0BfAT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0NjA4NjIJMjIyMzU4MzUxOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDMvMDFyCjIwMDYvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=D3MOuGnnEx1X%2FpNp2n3oJAcKa%2Bk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Syst%C3%A8mes+d%27Information+et+Management&rft.atitle=An+Exploratory+Framework+for+Assessing+Open+Source+Software+Adoption&rft.au=Miralles%2C+Francesc%3BSieber%2C+Sandra%3BValor%2C+Josep.&rft.aulast=Miralles&rft.aufirst=Francesc&rft.date=2006-03-01&rft.volume=11&rft.issue=1&rft.spage=85&rft.isbn=&rft.btitle=&rft.title=Syst%C3%A8mes+d%27Information+et+Management&rft.issn=12604984&rft_id=info:doi/","Open source software; Decision making; Qualitative research; Research methodology; Information technology; Studies; Business And Economics--Management; Open source; Software; Open-source software; Technology adoption; 5240:Software & systems; Public domain; Economic; Technological change; Systems development; 9130:Experimental/theoretical; 9175:Western Europe; France; Social responsibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through an empirical, interpretive case study and a literature review utilising the metaphor of text in the analysis, this paper provides a refined conceptualisation of user participation in OSS development. The paper reveals that different kinds of meanings have been attached to users and to their participation. User participation is both direct and indirect in the OSS development context. Some user groups actively take part in OSS development, while others are merely represented in it. Different kinds of intermediaries representing the users are identified. The research is based on one case study on a small but active OSS project with an interest in users. Other kinds of OSS projects should be analysed. The analysis was focused on a discussion forum, but users can take part in OSS development by other means as well. Paths for future work should include the gathering of more varied empirical data. The findings indicate that users can provide feedback to the development through discussion forums in the distributed environment, but there is a need to support the users in doing so and the developers in analysing the data. The importance of different kinds of intermediaries representing the users is highlighted. The paper provides thorough empirical insights and a refined conceptualisation of user participation addressing the currently weakly empirically explored OSS development context.","2009","2025-04-25 15:22:21","2025-04-25 15:22:21","","132-156","","2","22","","","","","","","","","","English","","","ABI/INFORM Global","222338127","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/FwwiT?_a=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&_s=NdT%2BgoS1qDJ7PNo2VOsmhjgpBak%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=%26quot%3BConstructing+the+users%26quot%3B+in+open+source+software+development%3A+An+interpretive+case+study+of+user+participation&rft.au=Iivari%2C+Netta.&rft.aulast=Iivari&rft.aufirst=Netta&rft.date=2009-04-01&rft.volume=22&rft.issue=2&rft.spage=132&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593840910962203","Design; Open source software; Decision making; Qualitative research; Information technology; Studies; User behavior; Open source; Participation; Software engineering; Software; Open-source software; Usability; Empowerment; Software development; Case study; 5240:Software & systems; Public domain; End users; Literature review; 9130:Experimental/theoretical; Industrial democracy; Library And Information Sciences--Computer Applications; Systems design; Human-computer interaction; Intermediary; Traditions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The dependence of OR on software implies that the ways in which software is developed, managed, and distributed can have a significant impact on the field. Open source is a relatively new software development and distribution model which offers advantages over current practices. Its viability depends on the precise definition of open source, on the culture of a distributed developer community, and on a version-control system which makes distributed development possible. In this paper, we review open-source philosophy and culture, and present the goals and status of COIN-OR.","2003-01","2025-04-25 15:22:21","2025-04-25 15:22:21","","57-66","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","220690110","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/OBJ/eiZTT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0MTEyMzIJMjIwNjkwMTEwOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDMvMDEvMDFyCjIwMDMvMDEvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=oig6YOxcjBpD8xE4hgp6afot6Gw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Journal+of+Research+and+Development&rft.atitle=The+common+optimization+INterface+for+operations+research%3A+Promoting+open-source+software+in+the+operations+research+community&rft.au=Lougee-Heimer%2C+R.&rft.aulast=Lougee-Heimer&rft.aufirst=R&rft.date=2003-01-01&rft.volume=47&rft.issue=1&rft.spage=57&rft.isbn=&rft.btitle=&rft.title=IBM+Journal+of+Research+and+Development&rft.issn=00188646&rft_id=info:doi/","Open source software; Computers; Collaboration; Open source; Libraries; Open-source software; Peer review; Software development; Algorithms; Mathematical programming; Optimization; Public domain; Technology: Comprehensive Works; Researchers; 51921:Libraries and Archives; Application programming interface; Interfaces; Mathematical optimization; Operations research; Software distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research examines why governments choose to migrate and what factors affect implementation. Drawing on a comparative case study of four cities, I find that governments decide to migrate for a range of factors, but are driven more by democratic values such as independence and self-determination than by a desire to cut costs or save money. I also find that implementation is affected by a variety factors but in particular by information technology's place within a city's organizational structure.

Software, however, is increasingly developed in open source software (OSS) forms which have several unique characteristics. In this study, we approach OSS RE as a sociotechnical, distributed cognitive process where distributed actors ""compute"" requirements- i.e., transform requirements-related knowledge into forms that foster a shared understanding of what the software is going to do and how it can be implemented. Such computation takes place through social sharing of knowledge and the use of heterogeneous artifacts. To illustrate the value of this approach, we conduct a case study of a popular OSS project, Rubinius-a runtime environment for the Ruby programming language-and identify ways in which cognitive workload associated with RE becomes distributed socially, structurally, and temporally across actors and artifacts. We generalize our observations into an analytic framework of OSS RE, which delineates three stages of requirements computation: excavation, instantiation, and testing-in-the-wild. We show how the distributed, dynamic, and heterogeneous computational structure underlying OSS development builds an effective mechanism for managing requirements. Our study contributes to sorely needed theorizing of appropriate RE processes within highly distributed environments as it identifies and articulates several novel mechanisms that undergird cognitive processes associated with distributed forms of RE.","2018","2025-04-25 15:22:21","2025-04-25 15:22:21","","1217-1252","","12","19","","","","","","","","","","English","","","ABI/INFORM Global","2172619875","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/auQH8?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=vxhN6j%2Be8Fs0IkGVdmku2nHlfT0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=%26quot%3BComputing%26quot%3B+Requirements+for+Open+Source+Software%3A+A+Distributed+Cognitive+Approach&rft.au=Xiao%2C+Xuan%3BLindberg%2C+Aron%3BHansen%2C+Sean%3BLyytinen%2C+Kalle.&rft.aulast=Xiao&rft.aufirst=Xuan&rft.date=2018-01-01&rft.volume=19&rft.issue=12&rft.spage=1217&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00525","Open source software; Interviews; Cognition; Information systems; Theory; Open source; Software engineering; Software; Open-source software; Knowledge; Research; Case studies; Computers--Information Science And Information Theory; Software development; Codes; Requirements engineering; Programming languages; Agile software development; Distributed computing; Public domain; Engineering; Cognition & reasoning; 51921:Libraries and Archives; Artifacts; Archives & records; Computation; Keywords; Requirements analysis; Verbal communication","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach – This paper uses the case study approach based on mixed methods: literature reviews and news searches, electronic surveys, qualitative interviews and observations. It combines discussions from several research projects as well as previous publications to present the scope of commercial choices within open source software and their consequences. Findings – The findings show that higher levels of involvement in open source software communities poses important questions about the balance between economic, technological, and social logics as well as the benefits of being autonomous, having access to collaborative networks and minimizing risks related to free-riding. There are six levels of commercial involvement in open source communities, and each of them is characterized by a different dilemma. Originality/value – The paper sheds light on the various level of involvement of business in open source movement and emphasize that the popularized “open innovation” concept is only the first step in real involvement and paradigm shift.","2016","2025-04-25 15:22:21","2025-04-25 15:22:21","","344-360","","3","29","","","","","","","","","","English","","","ABI/INFORM Global","2154276377","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/FIlx7?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=7%2FgAt8bWHwx7LBuGjUr96mUn598%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Change+Management&rft.atitle=Dilemmas+within+commercial+involvement+in+open+source+software&rft.au=Ciesielska%2C+Malgorzata%3BWestenholz%2C+Ann.&rft.aulast=Ciesielska&rft.aufirst=Malgorzata&rft.date=2016-04-01&rft.volume=29&rft.issue=3&rft.spage=344&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Change+Management&rft.issn=09534814&rft_id=info:doi/10.1108%2FJOCM-04-2013-0058","Open source software; Interviews; Community; Qualitative research; Business And Economics--Management; Open source; Participation; Software; Open-source software; Linux; Venture capital; Software development; Codes; Business models; Mixed-methods; Case study; Public domain; Surveys & questionnaires; Freeware; Innovations; Open innovation; Literature reviews; Open; Commercialization; Contradictory institutional logics; Dilemma","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The focus of the paper lies in a proof-of-concept for a novel means to develop and execute pervasive services, with simplicity and maintainability as prime drivers. The essence of this approach is the novel integration of the policy-based management (PBM) techniques and the model-driven architecture (MDA) techniques for specifying pervasive services and their behaviour, together with auto-generation of middleware implementation and policy enablement. The presence of policies provides pervasive services with the high flexibility and adaptability needed for dealing with changing environments and resource availabilities, while the introduction of MDA for defining pervasive service information models fundamentally solves the information modelling puzzle of current policy-based approaches. Additionally, MDA's middleware-neutral feature benefits the smooth evolution of pervasive services as a piece of software artefact in the face of heterogeneous devices and platforms. A preliminary case study has demonstrated the practical feasibility and benefits of this approach. The case study revolves around an ICT service called TEANU - transparent enterprise access for nomadic user. The service provides a means for nomadic users to maintain a secure access to their enterprise network in the presence of multiple access network providers with different service level guarantees.

This paper focuses on for-profit organizations that release software products under OSS licenses, and argues that variations in their endowments of intellectual property rights, namely patents and trademarks, help to determine which firms will tend to incorporate OSS into commercial products. We explain whether and under what conditions preexisting stocks of intellectual property rights can be useful complementary assets that allow firms to benefit directly or indirectly from commercializing OSS products, and test our hypotheses on a novel data set built on firms' announcements of OSS product releases in the specialized press between 1995 and 2003. We find three robust results: (a) firms with large stocks of software patents are more likely to release OSS products; (b) firms with large stocks of software trademarks are less likely to release OSS products; (c) firms with large stocks of hardware trademarks are more likely to release OSS products.

Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach – To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents’ opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings – The analysis of the data reveals that the individual participant’s satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value – Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members’ satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.","2015","2025-04-25 15:22:22","2025-04-25 15:22:22","","791-813","","4","19","","","","","","","","","","English","","","ABI/INFORM Global","2138080131","","","Place: Kempston Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/KZxi7?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0Njk1NzIKMjEzODA4MDEzMToNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDE1LzA3LzAxcgoyMDE1LzA4LzMxegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAg9BcnRpY2xlfEZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=%2B16Ipv0d5ANX8qBpgWJAhLCfOjM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Knowledge+Management&rft.atitle=Knowledge+sharing+in+open+source+software+communities%3A+motivations+and+management&rft.au=Iskoujina%2C+Zilia%3BRoberts%2C+Joanne.&rft.aulast=Iskoujina&rft.aufirst=Zilia&rft.date=2015-07-01&rft.volume=19&rft.issue=4&rft.spage=791&rft.isbn=&rft.btitle=&rft.title=Journal+of+Knowledge+Management&rft.issn=13673270&rft_id=info:doi/10.1108%2FJKM-10-2014-0446","Open source software; Online communities; Motivation; Community; Data analysis; Qualitative research; Business And Economics--Management; Collaboration; Virtual communities; Open source; Online community; Software; Open-source software; Product development; Management; Quantitative research; Factor analysis; Regression analysis; Knowledge management; Knowledge sharing; Project management; Public domain; Surveys & questionnaires; Research & development--R&D; Literature reviews; Correlation analysis; Explicit knowledge; Open source software communities; Open source software projects; Tacit knowledge; Test procedures; Work environment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper inductively derives a framework for understanding participation from the perspective of the individual software developer based on data from two software communities with different governance structures. In both communities, a need for software-related improvements drives initial participation. The majority of participants leave the community once their needs are met, however, a small subset remains involved. For this set of developers, motives evolve over time and participation becomes a hobby. These hobbyists are critical to the long-term viability of the software code: They take on tasks that might otherwise go undone and work to maintain the simplicity and modularity of the code. Governance structures affect this evolution of motives. Implications for firms interested in implementing hybrid strategies designed to combine the advantages of open source software development with proprietary ownership and control are discussed.

The notion of the OS business model is discussed in the light of a substantial body of theoretical literature concerning strategic management and the economics of innovation, as well as specialized literature on OS. Empirical evidence based on a survey of 146 Italian software firms shows that firms have adapted to an environment dominated by incumbent standards by combining the offering of proprietary and OS software under different licensing schemes, thus choosing a hybrid business model. The paper examines the determinants of the degree of openness toward OS and discusses the stability of hybrid models in the evolution of the industry.

This survey-based study, conducted with 402 active LUG members representing 191 different LUGs from 23 countries and employing structural equation modeling methodology, supports the proposed model. Furthermore, we find that the Linux user's experience level moderates the extent of the LUG's social influence and its impact on the user's participation.

Enterprises that are still discouraged by the task of converting existing software might find that modernization building blocks can make that task easier. Adapting or converting to OSS need not be overwhelming as this case study shows. There are many ways to use OSS in the enterprise, ranging from a few components to single applications, suites of related applications, and complete enterprise solutions.With such a diversity of applications, OSS use is even more attractive, yet it is not a trivial undertaking. The logistics of moving to OSS need not be daunting, however, if the organization considers the entire modernization plan, considers what various application types require, and does not undertake too much conversion at once.","2007-08","2025-04-25 15:22:22","2025-04-25 15:22:22","","28-33","","4","9","","","","","","","","","","English","","","ABI/INFORM Global","206314923","","","Place: Washington Publisher: IEEE Computer Society","","; ","https://media.proquest.com/media/hms/OBJ/EotNT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzMjY4NjIJMjA2MzE0OTIzOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDcvMDcvMDFyCjIwMDcvMDgvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=AI26cIb%2B2CTO0QHZuI0xHTHgLr8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IT+Professional+Magazine&rft.atitle=Open+Source+Software%3A+Is+It+Worth+Converting%3F&rft.au=Laplante%2C+Phillip%3BGold%2C+Anthony%3BCostello%2C+Thomas.&rft.aulast=Laplante&rft.aufirst=Phillip&rft.date=2007-07-01&rft.volume=9&rft.issue=4&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=IT+Professional+Magazine&rft.issn=15209202&rft_id=info:doi/10.1109%2FMITP.2007.72","Open source software; Open source; Software engineering; Software; Open-source software; Linux; Documentation; Software development; Software quality; Interoperability; 5240:Software & systems; Public domain; 2500:Organizational behavior; Innovations; Organization theory; United States--US; Engineering; 9190:United States; 2310:Planning; Open; Corporate planning; Modernization; Software modernization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

South Africa is Botswana's neighbor and both countries are leading economies in Africa. Design/methodology/approach - The paper draws on a survey that was carried out in information communication technology (ICT)-intensive government ministries in Botswana in May 2008. The study sought to establish availability of policy framework, level of usage of open source software, government support, motivations for implementing open source software in government, availability of skills, attitude of it managers in government toward open source software and challenges of open source software deployment in the public sector. The population of the study consisted of information technology (IT) managers who were purposively selected from ICT-intensive government ministries and interviewed. The study was extended to cover South Africa through review of literature on the same issues as those studied in Botswana. Findings - Compared with other countries in developed and developing countries including South Africa, there is limited use of open source software in the public sector in Botswana. However, IT managers in government of Botswana demonstrate a positive attitude toward open source software, and seem to have adequate understanding of its potential benefits. Comparatively, South African government provides support for harnessing open source software; awareness among top government officials is high and attitude toward open source software seems positive; skills are generally available and hardly any challenges of using open source software were identified. Research limitations/implications - This study was limited to purposively selected government ministries which are ICT-intensive in Botswana, while for South Africa, the study was based on secondary sources of data and focused on deployment of open source software in government agencies. Practical implications - Despite the increasing deployment of open source software in government across the world, the Botswanan government is yet unlikely to put in place an enabling open source software policy to harness the potential of the Software. Originality/value - Open source software deployment in government across the world is gaining momentum purportedly to enhance universal access, reduce costs associated with commercial software bridge the digital divide, grow indigenous IT skills, etc. Botswana and South Africa are the economic frontline states in Africa, and their leadership role in this matter among counterparts on the African continent is pertinent.

A key paradox of the global Internet is that it allows individual and collective decision making to co-exist with each other. Open source software (OSS) communities are a globally accelerating phenomenon. OSS refers to groups of programs that allow the free use of the software and further the code sharing to the general and corporate users of the software. The combination of private provision and public knowledge and software, and the seeming paradox of economic versus social motivations have stimulated a wide debate between researchers and policymakers. In this article, we analyze OSS communities from the viewpoint of ""intrinsic motivation,"" knowledge creation, and collective Internet governance. We believe that the growth of global OSS has fundamental implications for business ethics and the governance of the global Internet in the twenty-first century.

For this reason, this work aims to explore some of the effects of participation in a virtual brand community on consumer behaviour. The paper proposes the positive effects of participation in a virtual community on both consumer trust and loyalty to the product, brand or organisation around which the community is developed. In addition, it also proposes a positive effect of trust on consumer loyalty. After the validations of measurement scales, the hypotheses are contrasted through structural modelling. The data, obtained through a web survey using members of several free software virtual communities, show that participation in the activities carried out in a virtual community may foster consumer trust and loyalty to the mutual interest of the community (the free software in this case). In addition, the study also found a positive and significant effect of consumer trust on loyalty.","2007","2025-04-25 15:22:23","2025-04-25 15:22:23","","775-792","","6","31","","","","","","","","","","English","","","ABI/INFORM Global","194497941","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/FZrPT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNzE2MzIJMTk0NDk3OTQxOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDcvMTEvMDFyCjIwMDcvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=UdBSJueYZxEVhjUmemvKTzm2iOg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=The+impact+of+participation+in+virtual+brand+communities+on+consumer+trust+and+loyalty%3A+The+case+of+free+software&rft.au=Casal%C3%B3%2C+Luis%3BFlavi%C3%A1n%2C+Carlos%3BGuinal%C3%ADu%2C+Miguel.&rft.aulast=Casal%C3%B3&rft.aufirst=Luis&rft.date=2007-11-01&rft.volume=31&rft.issue=6&rft.spage=775&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/10.1108%2F14684520710841766","Communication; Social interaction; Community; Qualitative research; Studies; Computers--Internet; Virtual communities; Participation; Software; Consumer behavior; Group Dynamics; Consumers; Brand loyalty; Virtual community; Internet; Trust; Computer Mediated Communication; Social networks; Loyalty; Surveys & questionnaires; 9130:Experimental/theoretical; 7100:Market research; 5250:Telecommunications systems & Internet communications; Community Relations; Brand; Brand community; Community Involvement; Consumer behaviour; Customer retention; Electronic Mail; Information Sources; Literature Reviews; Virtual networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data.Design/methodology/approachThe methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample.FindingsThe quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning.Research limitations/implicationsThe results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning.Practical implicationsThis study allows the authors to highlight two main practical contributions for OSSCs’ directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables.Originality/valueThis paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).","2017","2025-04-25 15:22:23","2025-04-25 15:22:23","","534-554","","4","30","","","","","","","","","","English","","","ABI/INFORM Global","1915493022","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/FHmT7?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=U6iPPuKsbLfn2Ug5EJ3Vyj54%2B2w%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Enterprise+Information+Management&rft.atitle=How+do+Open+Source+software+companies+respond+to+institutional+pressures%3F+A+business+model+perspective&rft.au=Mouakhar%2C+Khaireddine%3BTellier%2C+Alb%C3%A9ric.&rft.aulast=Mouakhar&rft.aufirst=Khaireddine&rft.date=2017-07-01&rft.volume=30&rft.issue=4&rft.spage=534&rft.isbn=&rft.btitle=&rft.title=Journal+of+Enterprise+Information+Management&rft.issn=17410398&rft_id=info:doi/10.1108%2FJEIM-05-2015-0041","Open source software; Library And Information Sciences; Collaboration; Open source; Open-source software; Business model; Business models; Public domain; 51321:Software Publishers; Software industry; Strategic management; Value creation; Empirical analysis; Qualitative analysis; 14.14:COMMUNICATIONS AND INFORMATION TECHNOLOGY - SOFTWARE; Accommodation; Aggregates; Business competition; Quantitative analysis; Social activism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hierarchical configurations have been used to structure processes, overcome resistance and get things done. But is deliberate change also possible without formal structures and hierarchical influence? Design/methodology/approach This longitudinal, qualitative study investigates an open-source software (OSS) community named TYPO3. This case exhibits no formal hierarchical attributes. The study is based on mailing lists, interviews and observations. Findings The study reveals that deliberate change is indeed achievable in a non-hierarchical collaborative OSS community context. However, it presupposes the presence and active involvement of informal change agents. The paper identifies and specifies four key drivers for change agents' influence. Originality/value The findings contribute to organisational analysis by providing a deeper understanding of the importance of leadership in making deliberate change possible in non-hierarchical settings. It points to the importance of ""change-by-conviction"", essentially based on voluntary behaviour. This can open the door to reducing the negative side effects of deliberate change also for hierarchical organisations.","2017","2025-04-25 15:22:23","2025-04-25 15:22:23","","346-374","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1896276387","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/00TF7?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=VFG1%2F%2Fkpv60j9SnR5Iuidh4BRhA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Organizational+Analysis&rft.atitle=Deliberate+change+without+hierarchical+influence%3F+The+case+of+collaborative+OSS+communities&rft.au=N%C3%B8rskov%2C+Sladjana%3BKesting%2C+Peter%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=N%C3%B8rskov&rft.aufirst=Sladjana&rft.date=2017-03-01&rft.volume=25&rft.issue=2&rft.spage=346&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Organizational+Analysis&rft.issn=19348835&rft_id=info:doi/10.1108%2FIJOA-08-2016-1050","Science; Open source software; Interviews; Leadership; Qualitative research; Business And Economics--Management; Collaboration; Participation; Open-source software; Linux; Public domain; Freeware; Collaborative; Reputations; Strategic management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The projects and developers co-evolve in an ecosystem. To keep healthy evolution of such OSS ecosystems, there is a need of attracting and retaining developers, particularly project leaders and core developers who have major impact on the project and the whole team. Therefore, it is important to figure out the factors that influence developers' chance to evolve into project leaders and core developers. To identify such factors, we conducted a case study on the GNOME ecosystem. First, we collected indicators reflecting developers' subjective willingness to contribute to the project and the project environment that they stay in. Second, we calculated such indicators based on the GNOME dataset. Then, we fitted logistic regression models by taking as independent variables the resulting indicators after eliminating the most collinear ones, and taking as a dependent variable the future developer role (the core developer or project leader). The results showed that part of such indicators (e.g., the total number of projects that a developer joined) of subjective willingness and project environment significantly influenced the developers' chance to evolve into core developers and project leaders. With different validation methods, our obtained model performs well on predicting developmental core developers, resulting in stable prediction performance (0.770, F-value).","2017-03","2025-04-25 15:22:23","2025-04-25 15:22:23","","396-414","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","1875688833","","","Place: Beijing Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/xdbAX?_a=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&_s=ikTHU0ejKcL%2BRbadEjSt0YQrJag%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Computer+Science+and+Technology&rft.atitle=Developer+Role+Evolution+in+Open+Source+Software+Ecosystem%3A+An+Explanatory+Study+on+GNOME&rft.au=Cheng%2C+Can%3BLi%2C+Bing%3BLi%2C+Zeng-Yang%3BZhao%2C+Yu-Qi%3BLiao%2C+Feng-Ling.&rft.aulast=Cheng&rft.aufirst=Can&rft.date=2017-03-01&rft.volume=32&rft.issue=2&rft.spage=396&rft.isbn=&rft.btitle=&rft.title=Journal+of+Computer+Science+and+Technology&rft.issn=10009000&rft_id=info:doi/10.1007%2Fs11390-017-1728-9","Science; Open source software; Computers; Leadership; Studies; Collaboration; Open source; Computer science; Software; Regression analysis; Evolution; Case studies; Software development; Software ecosystem; Public domain; Software Projects; Developer; Dependent variables; Independent variables; Indicators; Logistic regression; Performance prediction; Regression models; Research & development--R&D; United States--US","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

HFOSS also integrates two volunteer-rich communities that have much in common: the humanitarian community and the open source community.

As legal entities, OSSF help communities attain their long-term goals, hold community assets, provide resources to communities, and balance interests amongst different stakeholders. When OSS started to draw more business interests, commercial companies became involved with open source communities. The emergence of OSSF provides a good platform and opportunities for companies to exert their influence in a more direct way. This article summarizes the author's recent research regarding the relationships between company involvement, governance, revenue, and OSSF. Key findings in the research reported in this article contribute to the existing literature on open source and non-profits.

OSS continues to gain momentum worldwide due to its low entry barrier, high quality and customizability. More information technology (IT) decision makers are favoring OSS over traditional packaged software as it becomes more aligned with organizational needs. OSS is now part of the IT mainstream, supporting many of the world's largest companies and government institutions. The role of OSS continues to expand, from deep within the infrastructure to the key applications that drive a business. Proprietary software vendors have sales and marketing teams to inform their customer base and provide detailed responses to RFIs (Requests for Information), RFPs (Requests for Proposal) or RFQs (Requests for Quotation). While many open source products and projects do not measure up to the EQS Directory standards, they can still be used in certain situations.","2008-05","2025-04-25 15:22:24","2025-04-25 15:22:24","","17-20","","","","","","","","","","","","","English","","","ABI/INFORM Global","1694724631","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/kteiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk0NzI0NjMxOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDgvMDUvMDFyCjIwMDgvMDUvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=sYjYBZWb6e6Qa62AdI4CyHRsu4c%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=OSS+FOR+CORPORATE+IT&rft.au=von+Rotz%2C+Bruno.&rft.aulast=von+Rotz&rft.aufirst=Bruno&rft.date=2008-05-01&rft.volume=&rft.issue=&rft.spage=17&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Infrastructure; Information technology; Business And Economics; Open source; Open-source software; Software packages; Software design; Trends; Software development; Software quality; 5240:Software & systems; Public domain; United States--US; 9190:United States; Corporation; Customer relationship management; Ratings & rankings; Request for proposal","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open sourcing software developments means sharing technology and resources with communities worldwide to help eliminate the digital divide, create economic opportunity, and support equal access to technology. Therefore, a methodological approach is needed to assess properly the performance and the value generation potential and to put such measure into organizational reports. International financial reporting framework is checked over conditions to allow value recognition of open sourced assets. Linux kernel development value is estimated to reflect worth of open source developments despite absence of book value due to inexistence of a single cost source. Several attempts to estimate a valuation of open source software have been performed previously. However, this study is the first to judge suitability of accounting framework to report on this value. The main finding is that open sourced assets do not fully accomplish conditions to be included in financial reports. We seek to stimulate academic and professional debate about the pursuit of valuation of a large and efficient ecosystem of software innovation, freely available to society.","2013-04","2025-04-25 15:22:24","2025-04-25 15:22:24","","3-16","","1","3","","","","","","","","","","Portuguese","","","ABI/INFORM Global","1692031926","","","Place: Senhor do Bonfim Publisher: Universidade do Estado da Bahia (UNEB) - Departamento de Ciências Humanas","","; ","https://media.proquest.com/media/hms/ORIG/1/Z65xB?_a=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%3D%3D&_s=%2FGKZ1afCSon8%2FPZtrUCYGuUXSwc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revista+de+Gest%C3%A3o%2C+Finan%C3%A7as+e+Contabilidade&rft.atitle=VALUATION+OF+OPEN+SOURCE+SOFTWARE%3A+HOW+DO+YOU+PUT+A+VALUE+ON+FREE%3F&rft.au=Garc%C3%ADa-Garc%C3%ADa%2C+Jesus%3BMar%C3%ADa+Isabel+Alonso+de+Magdaleno.&rft.aulast=Garc%C3%ADa-Garc%C3%ADa&rft.aufirst=Jesus&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=3&rft.isbn=&rft.btitle=&rft.title=Revista+de+Gest%C3%A3o%2C+Finan%C3%A7as+e+Contabilidade&rft.issn=&rft_id=info:doi/","Open source software; Business And Economics; open source software; Models; Statistical analysis; 5240:Software & systems; 9130:Experimental/theoretical; 4120:Accounting policies & procedures; accounting standards; Accounting standards; Financial reporting; Intangible assets","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 15:22:24","2025-04-25 15:22:24","","119-139","","1","39","","","","","","","","","","English","","","ABI/INFORM Global","1655249846","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/Q0uKV?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=R25kjKINZviPGbD5HDw%2FPkyDgc4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=Raising+the+general+public%27s+awareness+and+adoption+of+open+source+software+through+social+Q%26amp%3BA+interactions&rft.au=Choi%2C+Namjoo%3BYi%2C+Kwan.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-01-01&rft.volume=39&rft.issue=1&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/","Open source software; Motivation; Qualitative research; Studies; Computers--Internet; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

Results of the research suggest that: i) the actions of an open source software foundation are centered around one of three groups: Members, Chairman/President/Executive Director, and Board of Directors; ii) in only one of the six foundations is the Board of Directors responsible for both the community and the product; and iii) artificial neural network analysis of the content of bylaws provides unbiased insights of the power structure of open source software foundations.

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lock-in, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-04-25 15:22:24","2025-04-25 15:22:24","","7-12","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473085","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/nB2HV?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM0NTAwMgoxNjE0NDczMDg1Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTMvMDEvMDFyCjIwMTMvMDEvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCD0FydGljbGV8RmVhdHVyZdICAVnyAgD6AgFZggMDV2ViigMcQ0lEOjIwMjUwMjI3MDIwNDA3NjEzOjY2OTczMg%3D%3D&_s=NZyVa1ltHqsMgZMPP3rqT9Il6aw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=Code+Forking%2C+Governance%2C+and+Sustainability+in+Open+Source+Software&rft.au=Nyman%2C+Linus%3BLindman%2C+Juho.&rft.aulast=Nyman&rft.aufirst=Linus&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=7&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Business And Economics; Open source; open source software; Software; innovation; Open-source software; sustainability; Sustainability; Social; Software development; Public domain; Code; code forking; Freeware; planned obsolescence","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 15:22:24","2025-04-25 15:22:24","","32-39","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473053","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/y42HV?_a=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%3D%3D&_s=Nm%2Bs3gRvmsj2phuAD0rARjfdGCg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=The+Evolving+Role+of+Open+Source+Software+in+Medicine+and+Health+Services&rft.au=Ingram%2C+David%3BSevket+Seref+Arikan.&rft.aulast=Ingram&rft.aufirst=David&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Research & development--R&D; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within the context of a knowledge-based economy, this sort of approach appears exemplary for a growing number of industrial activities in which the amount of knowledge that has to be mastered is too large for a single agent, however powerful. Considering knowledge as a mutual resource requires a rethinking of the value chain concept, since cash flow is derived from use of the knowledge base (services, complementary products), not from the knowledge itself. In a classical industrial economics perspective, this reshaping of the value chain must be analyzed not only at the global ecosystem level (who produces what, between firms and universities, users and producers, etc.), but also at the industrial level (once the industry's role has been identified, how does it organize itself?). In this article, we argue for a more structured and global analysis, based on the tools of industrial economics, and thus starting from the basic conditions of the computer market and of the buyers' competence in software development (the ""dominant user's skill"").","2011","2025-04-25 15:22:24","2025-04-25 15:22:24","","39-64","","136","","","","","","","","","","","English","","","ABI/INFORM Global","1586117409","","","Place: Brussels Publisher: Editions De Boeck Superieur","","; ","https://media.proquest.com/media/hms/OBJ/zKIGV?_a=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%3D%3D&_s=ZcfgsSodIWlaAtubQXMmN1s8MVw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revue+d%27%C3%89conomie+Industrielle&rft.atitle=FLOSS+IN+AN+INDUSTRIAL+ECONOMICS+PERSPECTIVE&rft.au=Jullien%2C+Nicolas%3BZimmermann%2C+Jean-Beno%C3%AEt.&rft.aulast=Jullien&rft.aufirst=Nicolas&rft.date=2011-10-01&rft.volume=&rft.issue=136&rft.spage=39&rft.isbn=&rft.btitle=&rft.title=Revue+d%27%C3%89conomie+Industrielle&rft.issn=01543229&rft_id=info:doi/","Open source software; Computers; Information technology; Open-source software; Competition; Operating systems; Economics; Software development; Organizational behavior; Computer industry; 5240:Software & systems; 2500:Organizational behavior; 9175:Western Europe; Industrial economics; Value chain; 1130:Economic theory; Competitive advantage; Free and open-source software; 33411:Computer and Peripheral Equipment Manufacturing; Business And Economics--Production of Goods And Services; Floss; France; Computer based modeling; Expert systems; Generic products; Industrial organization; Knowledge base","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Specifically, I posit that within an organization 's IT department, OSS opinion leaders should have different social network profiles in terms of degree of centrality, betweenness, closeness and in-degree centrality from their peers who are not OSS opinion leaders. I also postulate that differences exist in the two groups' demographic characteristics such as age, educational level, tenure in organization, position in organization, and personality profiles such as openness and extraversiOn. A field survey using Social Network Analysis technique was carried out to test the hypotheses. Based on the findings, important theoretical and practical implications are identified.","2014","2025-04-25 15:22:25","2025-04-25 15:22:25","","1-10","","4","54","","","","","","","","","","English","","","ABI/INFORM Global","1548674998","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","; ","https://media.proquest.com/media/hms/OBJ/dDdCV?_a=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&_s=O3Shm2d9ZOwTn3CGWIOKZPqONhE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=SOCIAL+CAPITAL+CHARACTERISTICS+OF+OPEN+SOURCE+SOFTWARE+OPINION+LEADERS&rft.au=Yan%2C+Li.&rft.aulast=Yan&rft.aufirst=Li&rft.date=2014-07-01&rft.volume=54&rft.issue=4&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/","Open source software; Computers; Leadership; Communication; Social network analysis; China; Social capital; Studies; Open source; Open-source software; Technology adoption; Influence; Power; Social networks; 9130:Experiment/theoretical treatment; Public domain; 9179:Asia & the Pacific; 1220:Social trends & culture; Employees; Perceptions; 5220:Information technology management; Opinion leadership; Communications networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is a complicated social process to understand. OSS is a multi-faceted phenomenon including code, a licensing structure, a community, development best practices, a method of diffusion. However, the current OSS collaborative researches place too much emphasis on collaborative behaviors, but ignore the study on collaborative process. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and level of collaboration between collaborators. Based on the definition of three types of contact behavior, this paper presents an approach to measuring the contact relationship intensity. Based on introducing and improving TF-IDF (term frequency-inverse document frequency), this paper presents the methods for calculating tag weights and work similarity between collaborators. Finally, by evaluating the model using data from the OSS website www.Codeplex .com, we verify that our model outperforms conventional models in both describing and forecasting collaborative behavior.

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help ""transfer"" their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

Different approaches for introducing usability activities into SW development have not yet been evaluated with respect to open source software (OSS). This paper tests the introduction of usability activities through four empirical case studies in the OSS development context. Case studies were carried out using four OSS projects that were not commercially supported. Empirical analysis suggests that usability specialists should become members of the OSS community, but, at the same time, should keep an objective view. The usability activities had substantially more impact when specialists introduced and carried them out as fellow members of the OSS community than as usability consultants from outside the community. The importance of management commitment for usability activities is discussed in the OSS context. The challenge of adapting usability and OSS development philosophies together should be researched further.

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 15:22:25","2025-04-25 15:42:03","","156-187","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1018105738","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/wxbVU?_a=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&_s=5S7bea3gFvTMEM%2F05u2ZFWpFKOA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Information+Technology+%26+People&rft.atitle=Adoption+of+free%2Flibre+open+source+software+in+public+organizations%3A+factors+of+impact&rft.au=Rossi%2C+Bruno%3BRusso%2C+Barbara%3BSucci%2C+Giancarlo.&rft.aulast=Rossi&rft.aufirst=Bruno&rft.date=2012-04-01&rft.volume=25&rft.issue=2&rft.spage=156&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593841211232677","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Technology; Case studies; Technology adoption; Migration; Adoption; Case study; 5240:Software & systems; Public domain; Innovations; Public sector; 9130:Experimental/theoretical; Open standards; Cost control; Business process re-engineering; Disruptive innovation; Environmental factor; Library And Information Sciences--Computer Applications; Software services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper aims to illustrate that if Free and/or Open Source Software is to be used as a building block to bridge the ""digital divide"" a more social and environmental perspective, which embraces the philosophy behind the software, needs to complement the technical perspective. The human environmental model is presented as a useful alternative which, if embraced, can inform more holistic information and communication technology (ICT) policies. Design/methodology/approach - Through a review of diffusion of innovations models an alternative diffusion framework is described and applied to an interpretive open source case study in South Africa. Findings - Contemporary diffusion and innovation models are narrowly focused on IT as a purely technological linear phenomenon. This perspective also underlies many ICT policies. A more socio-technical adoption model can assist in providing a more holistic approach to ICT policy development. Originality/value - The application of a new innovation model, the human environmental model, to ICT policy provides a holistic framework in which the complexity of the innovation process can be reflected in policy. Such an approach to ICT policy formulation will assist with broadening the perspective of policy makers from IT as a technical solution to IT as part of a socio-technical solution and recognise the duality of the innovation process.","2010","2025-04-25 15:22:25","2025-04-25 15:22:25","","108-123","","1","8","","","","","","","","","","English","","","ABI/INFORM Global","1011911286","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/mpsTU?_a=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&_s=8%2FidtJ78c4ZfaFFFTieuCb%2F0c%2BA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.atitle=A+human+environmentalist+approach+to+diffusion+in+ICT+policies%3A+A+case+study+of+the+FOSS+policy+of+the+South+African+Government&rft.au=Weilbach%2C+Lizette%3BByrne%2C+Elaine.&rft.aulast=Weilbach&rft.aufirst=Lizette&rft.date=2010-01-01&rft.volume=8&rft.issue=1&rft.spage=108&rft.isbn=&rft.btitle=&rft.title=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.issn=1477996X&rft_id=info:doi/10.1108%2F14779961011024837","Philosophy; Information technology; Studies; Open-source software; Diffusion; Organizational change; Economic; Technological change; Innovations; Perceptions; Business process reengineering; Communication channels; Departments; Developing countries--LDCs; Diffusion of innovations; Environmental modeling; Environmentalists","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In more recent years, FOSS is becoming an increasingly important element in strategies for development and implementation of information and communication technologies also in developing countries. Mainstream research on FOSS has catered to the underlying principles or freedom, open organizational forms, and on its economical aspects. The purpose of this paper is to shed new light on the actual consequences of FOSS, often left in the background. Design/methodology/approach - The paper examines where FOSS principles' assumptions are likely to be more evident: in contexts of developing countries, which are geographically and organizationally far from the original environment of FOSS. A mixed methodology characterizes this work: quantitative and qualitative methods bring readers' attention to unusual empirical settings and downplayed organizational processes of information technology (IT) implementation and adoption. Findings - The consequences of FOSS on IT implementation and actual use are ambivalent. It is argued that FOSS adoption does not happen spontaneously, neither by decree, and that the relevance of open technologies as public goods remains in the different role of local actual technical and organizational capabilities, and environment conditions. Originality/value - Such a focus complements existing studies on the economical relevance of FOSS, which are not the focus of this paper.","2010","2025-04-25 15:22:26","2025-04-25 15:22:26","","42-56","","1","8","","","","","","","","","","English","","","ABI/INFORM Global","1011911065","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/6lsTU?_a=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%3D%3D&_s=%2BFbGY6VK%2BngJpAtQmuKRq7ybKEA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.atitle=Free+and+Open+Source+Software+in+developing+contexts%3A+From+open+in+principle+to+open+in+the+consequences&rft.au=Miscione%2C+Gianluca%3BJohnston%2C+Kevin.&rft.aulast=Miscione&rft.aufirst=Gianluca&rft.date=2010-01-01&rft.volume=8&rft.issue=1&rft.spage=42&rft.isbn=&rft.btitle=&rft.title=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.issn=1477996X&rft_id=info:doi/10.1108%2F14779961011024800","Open source software; India; Politics; Philosophy; Decision making; Information technology; Studies; Open source; Software; Competition; Technology adoption; Influence; Costs; South Africa; Public domain; Economic; Technological change; Proprietary; Free and open-source software; Developing countries--LDCs; Developing country; Small & medium sized enterprises-SME; Computer literacy; Development strategies; Environmental impact; Information and communications technology; National security; Skill development; Skills","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted an abductive, computationally intensive study of eight OSS projects, using relational event modeling to analyze 1,169,489 actions covering 93 major software releases. The process of entrainment that we identify involves three task allocation mechanisms: (1) developer-issue inertia, (2) developer contribution frequency, and (3) issue popularity. Our analysis demonstrates that these mechanisms and the phases of the release cycle entrain each other. Before a major release, developers engage in a concentrated mobilization phase, whereby they democratize development activity and increasingly allocate community contributions to the set of issues related to the release. After a major release, the extended cleanup phase garners a greater share of development work from recently highly active developers and dilutes the activity of these developers across a wider range of issues. Our theorizing suggests that major releases constitute important events around which OSS communities self-organize and we characterize how this occurs. Our research contributes to theorizing on organizing in OSS communities by explaining how self-organizing task allocation interacts with release cycles through the mechanism of entrainment. We also contribute to the literature on entrainment by showing how it may unfold in the context of online peer production communities such as OSS.","2024-03","2025-04-25 15:23:16","2025-04-25 15:23:16","","67","","1","48","","","","","","","","","","English","","","ABI/INFORM Global","3076685766","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Entrainment+of+Task+Allocation+and+Release+Cycles+in+Open+Source+Software+Development&rft.au=Lindberg%2C+Aron%3BSchecter%2C+Aaron%3BBerente%2C+Nicholas%3BHennel%2C+Phil%3BLyytinen%2C+Kalle.&rft.aulast=Lindberg&rft.aufirst=Aron&rft.date=2024-03-01&rft.volume=48&rft.issue=1&rft.spage=67&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2023%2F16789","Open source software; Computers; Software; Software development; Optimization; Public domain; Resource allocation; Impact fees; Entrainment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We investigated 355 F/OSS software package websites for the presence of codes of conduct and then analyzed these for diversity elements. Qualitative content analysis of the websites shows that less than 10% (28) of the analyzed websites had some type of community rules such as CoC. In-depth analysis of the CoCs demonstrated many discrepancies in the terminology, length, enforcement, and adoption of codes of conduct. To investigate the usage of these CoCs, we investigate five women-focused OSS discussion forums. This analysis shows the value of creating/adopting a CoC and the impact CoC can have on the participation of women. We also present the challenges in the usage and enforcement of CoCs as discussed by women of these forums. We conclude with recommendations for better enforcement of CoC and reflection on the ethical underpinnings of CoC as a tool to improve diversity and inclusion in OSS.","2022-06","2025-04-25 15:23:16","2025-04-25 15:23:16","","581-620","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2681285630","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/f2aON?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=ZpVx1S6wrFO46n7oTR4%2BxuUtGlY%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Codes+of+conduct+in+Open+Source+Software%26mdash%3Bfor+warm+and+fuzzy+feelings+or+equality+in+community%3F&rft.au=Singh%2C+Vandana%3BBongiovanni%2C+Brice%3BBrandon%2C+William.&rft.aulast=Singh&rft.aufirst=Vandana&rft.date=2022-06-01&rft.volume=30&rft.issue=2&rft.spage=581&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-020-09543-w","Open source software; Community; Open source; Online community; Software; Open-source software; Software packages; Diversity; Content analysis; Public domain; Freeware; Computers--Software; Multiculturalism & pluralism; Qualitative analysis; Websites; Community participation; Code of conduct; Diversity and inclusion; Enforcement; Gender and IT; Woman; Women in open source","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considering the characteristics of OSS development and management projects, operation performance measures for OSS project management will take an irregular fluctuation in the long term of operation, because several developer and many users are closely related to the maintenance of OSS. Also, OSS projects will heavily depend the environment of internet network. This paper focuses on the irregular fluctuation of operation performance measures for OSS project management. We apply the double jump diffusion process models to the noisy cases in the operation of OSS. In particular, the maintenance effort is estimated by the stochastic differential equation model in terms of OSS project management. Moreover, we propose the method of maintenance effort management based on the double jump diffusion process model considering the irregular fluctuation of performance for OSS projects. Thereby, it will be helpful for the OSS developers and managers to understand the maintenance effort status of OSS from the standpoint of OSS project management.

While we can attribute identified peripheral contributions (IPC) to specific individuals and OSS projects need them to succeed, one cannot trace back anonymous peripheral contributions (APC), and they can have both positive and negative ramifications for project development. Open platforms and managers face a challenging design choice in deciding whether to allow APC and for which tasks or what type of projects. We examine the impact that the ratio between APC and IPC has on OSS project performance. Our results suggest that the OSS projects perform the best when they contain a uniform anonymity level (i.e., they contain predominantly APC or predominantly IPC). However, our results also suggest that OSS projects have lower performance when the ratio between APC and IPC nears one (i.e., they contain close to the same number of APC and IPC). Furthermore, our results suggest that these results differ depending on the type of application that a project develops. Our study contributes to the ongoing debate about the implications of anonymity for online communities and informs managers about the effect that anonymous contributions have on their projects.","2020-09","2025-04-25 15:23:16","2025-04-25 15:23:16","","146-171","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","2499402496","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/Z6AVI?_a=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%3D%3D&_s=OU4G4vhkgPLL%2F9GCRiloqaHyxSc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=AIS+Transactions+on+Human-Computer+Interactions&rft.atitle=The+Impact+of+Anonymous+Peripheral+Contributions+on+Open+Source+Software+Development&rft.au=Daniel%2C+Sherae+L%3BTing-Ting+%28Rachel%29+Chung%3BSharma%2C+Pratyush+Nidhi.&rft.aulast=Daniel&rft.aufirst=Sherae&rft.date=2020-09-01&rft.volume=12&rft.issue=3&rft.spage=146&rft.isbn=&rft.btitle=&rft.title=AIS+Transactions+on+Human-Computer+Interactions&rft.issn=&rft_id=info:doi/10.17705%2F1thci.00133","Open source software; Computers; Privacy; Open source; Online community; Software; Open-source software; Open Source Software; Anonymity; Managers; Peer Production; Software development; Public domain; Anonymous Peripheral Contribution; Project development; Project Performance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These offer an opportunity to evaluate the generalizability of the original study to projects of different sizes and amount of activity, yet similar otherwise to the project in the original study. Another extension is the use of an additional control variable, length of activity sequence, which proves to have substantial implications of the study’s focal relationships. We find that three out of the four projects we analyze support the findings of the original study as it pertains to four relationships in the original study: order variation and developer interdependencies, activity variation and developer interdependencies, order variation and development interdependencies, and development and developer interdependencies. We also discuss the implications of our findings, especially in cases where the replication results differ from those in the original study and offer suggestions for future research that can help advance this stream of research.","2020","2025-04-25 15:23:16","2025-04-25 15:23:16","","14","","","6","","","","","","","","","","English","","","ABI/INFORM Global","2499402545","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/P8BUI?_a=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%3D%3D&_s=de4bXNlJyrljqUKWItXwCZkugxk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=AIS+Transactions+on+Replication+Research&rft.atitle=Coordinating+Interdependencies+in+an+Open+Source+Software+Project%3A+A+Replication+of+Lindberg%2C+et+al.&rft.au=Bradley%2C+Randy%3BMockus%2C+Audris%3BMa%2C+Yuxing%3BZaretzki%2C+Russell%3BBichescu%2C+Bogdan.&rft.aulast=Bradley&rft.aufirst=Randy&rft.date=2020-01-01&rft.volume=6&rft.issue=&rft.spage=14&rft.isbn=&rft.btitle=&rft.title=AIS+Transactions+on+Replication+Research&rft.issn=&rft_id=info:doi/10.17705%2F1atrr.00057","Open source software; Open source; Software; Open-source software; Open Source Software; Coordination; Replication; Public domain; Sciences: Comprehensive Works; Software project management; Interdependencies","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Similarly, the software project life-spans are related to some internal or external characteristics. Analyzing the relations between these characteristics and the project life-span, may help developers, investors, and contributors to control the development cycle of the software project. The paper provides an insight on the project life-span for a free open source software ecosystem. The statistical analysis of some project characteristics in GitHub is presented, and we find that the choices of programming languages, the number of files, the label format of the project, and the relevant membership expressions can impact the life-span of a project. Based on these discovered characteristics, we also propose a prediction model to estimate the project life-span in open source software ecosystems. These results may help developers reschedule the project in open source software ecosystem.","2019-08","2025-04-25 15:23:16","2025-04-25 15:38:18","","1382-1391","","4","24","","","","","","","","","","English","","","ABI/INFORM Global","1992797490","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/z90ZA?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=iAyKXLD0BsgqHguvU0xopSL2oz8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Mobile+Networks+and+Applications&rft.atitle=A+Prediction+Model+of+the+Project+Life-Span+in+Open+Source+Software+Ecosystem&rft.au=Liao%2C+Zhifang%3BZhao%2C+Benhong%3BLiu%2C+Shengzong%3BJin%2C+Haozhi%3BHe%2C+Dayu%3BLiu%2C+Yang%3BZhang%2C+Yan%3BWu%2C+Jinsong.&rft.aulast=Liao&rft.aufirst=Zhifang&rft.date=2019-08-01&rft.volume=24&rft.issue=4&rft.spage=1382&rft.isbn=&rft.btitle=&rft.title=Mobile+Networks+and+Applications&rft.issn=1383469X&rft_id=info:doi/10.1007%2Fs11036-018-0993-3","Open source software; GitHub; Computers--Computer Networks; Open source; Software engineering; Software; Software ecosystems; Programming languages; Statistical analysis; Software ecosystem; Public domain; Freeware; Mathematical models; Software project management; Open source software ecosystem; Project characteristics; Project life-span","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By the turn of the millennium, FOSS developers had created the GNU/Linux operating system and several other significant products. FOSS is now a crucial part of the networked world, providing both software—for example web servers, desktop environments, and the FOSS-derived Android operating system that powers the majority of the world's mobile phones—and many of the programming languages in which that software is written. In one crucial respect (the production of the so-called ""kernel"" of the system) this effort stalled, and only the efforts of a project initiated in 1991 by Finnish student Linus Torvalds enabled the production of a complete operating system, usually simply called Linux.","2019-04","2025-04-25 15:23:16","2025-04-25 15:23:16","","655-657","","2","60","","","","","","","","","","English","","","ABI/INFORM Global","2273232637","","","Place: Baltimore Publisher: Johns Hopkins University Press","","; ","https://media.proquest.com/media/hms/PFT/1/ndmoA?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzNTE4MjIKMjI3MzIzMjYzNzoNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDE5LzA0LzAxcgoyMDE5LzA0LzMwegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAgZSZXZpZXfSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Uin3nZ16VqS1y7MAHZFlsXycJTE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+and+Culture&rft.atitle=For+Fun+and+Profit%3A+A+History+of+the+Free+and+Open+Source+Software+Revolution+by+Christopher+J.+Tozzi+%28review%29&rft.au=Priestley%2C+Mark.&rft.aulast=Priestley&rft.aufirst=Mark&rft.date=2019-04-01&rft.volume=60&rft.issue=2&rft.spage=655&rft.isbn=&rft.btitle=&rft.title=Technology+and+Culture&rft.issn=0040165X&rft_id=info:doi/10.1353%2Ftech.2019.0058","Open source software; Russia; Open source; Software; Open-source software; Linux; Operating systems; Social; Free software; Software development; Programming languages; Servers; Public domain; Technological change; Freeware; Smartphones; Technology: Comprehensive Works; Books; France; Commercialization; Android; Finnish language; Mobile operating systems; Mobile phones; Monographs; Revolutions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considering the characteristics of OSS development and management projects, operation performance measures for OSS project management will take an irregular fluctuation in the long term of operation, because several developer and many users are closely related to the maintenance of OSS. Also, OSS projects will heavily depend the environment of internet network. This paper focuses on the irregular fluctuation of operation performance measures for OSS project management. We apply the double jump diffusion process models to the noisy cases in the operation of OSS. In particular, the maintenance effort is estimated by the stochastic differential equation model in terms of OSS project management. Moreover, we propose the method of maintenance effort management based on the double jump diffusion process model considering the irregular fluctuation of performance for OSS projects. Thereby, it will be helpful for the OSS developers and managers to understand the maintenance effort status of OSS from the standpoint of OSS project management. Also, we analyze actual data to show numerical examples of the proposed models with the characteristics considering noisy and jump of OSS projects.","2019-02","2025-04-25 15:23:17","2025-04-25 15:23:17","","1-16","","","","","","","","","","","","","English","","","ABI/INFORM Global","2182956604","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/7EsS8?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=QGw0xhrKfxFDDZrSZK8OfAWFV%2FU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Annals+of+Operations+Research&rft.atitle=Maintenance+effort+management+based+on+double+jump+diffusion+model+for+OSS+project&rft.au=Tamura%2C+Yoshinobu%3BYamada%2C+Shigeru.&rft.aulast=Tamura&rft.aufirst=Yoshinobu&rft.date=2019-02-01&rft.volume=&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Annals+of+Operations+Research&rft.issn=02545330&rft_id=info:doi/10.1007%2Fs10479-019-03170-w","Open source software; Computers; Open-source software; Diffusion; Project management; Maintenance; Mathematical models; Differential equations; Operations research; Operation support systems; Double jump diffusion process model; Maintenance effort; Variation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thereby it is important to release multiple version software products in order to add new features in the next release and fix remaining faults from previous release. In this paper, we develop a multi-release software reliability model with consideration of the remaining software faults from previous release and the new introduced-faults (from newly added features). Additionally, dependent fault detection process is taken into account in this research. In particular, the detection of a new fault for developing the next release depends on the detection of the remaining faults from previous release and the detection of the new introduced-faults.

Richard Stallman, founder of the Free software movement, has argued that creating and distributing non-Free software is always a moral injustice. In this essay, I try to identify the ethical foundations of Stallmanism. I identify three major trends in Stallman’s thinking—libertarian, utilitarian, and communitarian—and I argue that none is sufficient to justify the radical claim that distributing non-Free software is always wrong (unless we accept extremely demanding ethical standards that Stallman himself does not consistently endorse). I recommend thinking of Stallmanism as an attempt to optimize the satisfaction of a number of core values, including freedom, cooperation, and happiness, and I stress the importance of connecting the Free software movement to other political struggles against oppression.","2018-09","2025-04-25 15:23:17","2025-04-25 15:23:17","","437-453","","3","31","","","","","","","","","","English","","","ABI/INFORM Global","1969424199","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/wWvp6?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=w0jz8lM3JLz46ko1Q3GYSOz5Sh4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Philosophy+%26+Technology&rft.atitle=Is+Proprietary+Software+Unjust%3F+Examining+the+Ethical+Foundations+of+Free+Software&rft.au=Rappaport%2C+Jesse.&rft.aulast=Rappaport&rft.aufirst=Jesse&rft.date=2018-09-01&rft.volume=31&rft.issue=3&rft.spage=437&rft.isbn=&rft.btitle=&rft.title=Philosophy+%26+Technology&rft.issn=22105433&rft_id=info:doi/10.1007%2Fs13347-017-0294-y","Open source software; Sociology; Ethics; Software; Free software; Freeware; Source code; Communitarianism; Computer ethics; Libertarianism; Stallman; Utilitarianism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Le premier, celui de l’immatériel, consiste à aborder le cyberespace comme un monde informationnel doté de propriétés distinctes de celles du monde physique. Le second, celui de la déterritorialisation, présente les collectifs en ligne comme détachés de tout ancrage territorial. L’article montre la manière dont ces lieux communs habitent la culture du logiciel libre, en revenant aux origines de celle-ci au sein du AI Lab du MIT, en examinant l’influence exercée sur elle par la pensée cybernétique et en analysant le processus d’extension et de globalisation du free software. L’article développe également une critique de ces topoï, en montrant qu’ils contribuent à occulter la continuité entre les transformations du monde numérique et celles du reste de la société. La conclusion revient sur l’essor récent du mouvement maker, fortement influencé par le logiciel libre, et met en avant la persistance des enjeux liés à la matière et au territoire, y compris au sein de la culture numérique.Alternate abstract:This article questions two ideas that have become commonplace in digital culture, and particularly in free software culture. The first one is the idea that cyberspace is an immaterial (or informational) space, exhibiting properties that are radically distinct from the ones of the material world. The second one is the idea of deterritorialization, according to which online communities are indifferent to the geographical reality of the territory. The article explains how these commonplace assumptions pervade free software culture, tracing their history back to cybernetics and the AI Lab at the MIT, and analyzing the globalization of free software culture since the 1990s. It also criticizes these topoï that often conceal how the transformations of the digital world are intertwined with the transformations of society at large. The conclusion tackles the emergence of the maker movement (which is strongly tied to free software culture) and insists on the persistence of issues related to materiality and territory, even within digital culture.?","2018","2025-04-25 15:23:17","2025-04-25 15:23:17","","15-32","","1","20","","","","","","","","","","French","","","ABI/INFORM Global","2169345044","","","Place: Cachan Publisher: Lavoisier","","; ","https://media.proquest.com/media/hms/PFT/1/OHRF8?_a=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%3D%3D&_s=nNLe%2BrM1H5B2Uuyi2WPZVXtPtx0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Ge%CC%81ographie%2C+Economie%2C+Socie%CC%81te%CC%81&rft.atitle=Mati%26egrave%3Bre+et+territoire+dans+la+culture+du+logiciel+libre&rft.au=BROCA%2C+S%C3%A9bastien.&rft.aulast=BROCA&rft.aufirst=S%C3%A9bastien&rft.date=2018-01-01&rft.volume=20&rft.issue=1&rft.spage=15&rft.isbn=&rft.btitle=&rft.title=Ge%CC%81ographie%2C+Economie%2C+Socie%CC%81te%CC%81&rft.issn=1295926X&rft_id=info:doi/10.3166%2Fges.20.+2017.0027","free software; Software; cybernetics; Colonies & territories; Geography; Internet; Culture; Freeware; Globalization; Cybernetics; cybernétique; déterritorialisation; deterritorialization; Deterritorialization; immaterial; immatériel; logiciel libre; makers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Providing business strategy to benefit from volunteer developers for the purpose of contributing to existing projects, as well as initiating new OSS projects is of utmost significance for companies in that industry. Therefore, it is important to figure out how groups of volunteer developers are formed as new developers join existing projects, and it is even more important to investigate what causes these developers to initiate new projects. The authors investigate network structure as a causal factor for both new project initiation within a group (representing group innovation) as well as new developers joining existing projects within a group (representing group growth). The authors develop four hypotheses. 1. Intra-group coupling has a positive impact on group growth, 2. Inter-group coupling has a positive impact on group innovation, 3. Inter-group structural hole has a positive impact on group innovation, 4. There is a trade-off between the effects of inter-group structural hole and inter-group coupling on group innovation. The authors test these four hypotheses using data from OSS. Developers contributing to project tasks in groups other than their own can explore novel ideas for new project creation, because they can benefit from sharing knowledge, whereas developers contributing to project tasks inside their own group exploit ideas to improve those existing projects with better inside-group search possibility; and this demands more developers to join those group projects.","2017","2025-04-25 15:23:17","2025-04-25 15:23:17","","7-18","","1","15","","","","","","","","","","English","","","ABI/INFORM Global","2221307949","","","Place: Sumy Publisher: Business Perspectives Ltd.","","; ","https://media.proquest.com/media/hms/PFT/1/oiYA9?_a=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%3D%3D&_s=g3BXggG%2BVDYuRpLQ5xm2lAxzvJs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Problems+and+Perspectives+in+Management&rft.atitle=Network+tie+structure+causing+OSS+group+innovation+and+growth&rft.au=Behfar%2C+Stefan+Kambiz%3BTurkina%2C+Ekaterina%3BBurger-Helmchen%2C+Thierry.&rft.aulast=Behfar&rft.aufirst=Stefan&rft.date=2017-01-01&rft.volume=15&rft.issue=1&rft.spage=7&rft.isbn=&rft.btitle=&rft.title=Problems+and+Perspectives+in+Management&rft.issn=17277051&rft_id=info:doi/10.21511%2Fppm.15%281%29.2017.01","Open source software; Innovation; Business And Economics--Management; open source software; Hypotheses; Open-source software; Product development; Volunteers; Innovations; cluster management; network management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Free software is the best choice when the reduction of production costs is necessary; nevertheless, the quality of free software may vary. This paper probably does not include all of the free software, but tries to describe or mention at least the most interesting programs. The first part of this paper summarizes the essential knowledge about UAVs, including the fundamentals of flight mechanics and aerodynamics, and the structure of a UAV system. The second section generally explains the modelling and simulation of a UAV. In the main section, more than 50 free programs for the design, analysis, modelling, and simulation of a UAV are described. Although the selection of the free software has been focused on small subsonic UAVs, the software can also be used for other categories of aircraft in some cases; e.g. for MAVs and large gliders. The applications with an historical importance are also included. Finally, the results of the analysis are evaluated and discussed--a block diagram of the free software is presented, possible connections between the programs are outlined, and future improvements of the free software are suggested.","2016-09","2025-04-25 15:23:17","2025-04-25 15:23:17","","449-514","","3","23","","","","","","","","","","English","","","ABI/INFORM Global","1814065468","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/ORIG/1/jEVwB?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcxNDg2MzUyMgoxODE0MDY1NDY4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTYvMDkvMDFyCjIwMTYvMDkvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCD0FydGljbGV8RmVhdHVyZdICAVnyAgD6AgFOggMDV2ViigMcQ0lEOjIwMjUwMjI3MDIwNDA3NjEzOjY2OTczMg%3D%3D&_s=6%2Fhz06HHcsUY4H4%2FGWDS3X1Vc9o%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Archives+of+Computational+Methods+in+Engineering&rft.atitle=A+Survey+of+Free+Software+for+the+Design%2C+Analysis%2C+Modelling%2C+and+Simulation+of+an+Unmanned+Aerial+Vehicle&rft.au=Vogeltanz%2C+Tom%C3%A1s.&rft.aulast=Vogeltanz&rft.aufirst=Tom%C3%A1s&rft.date=2016-09-01&rft.volume=23&rft.issue=3&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Archives+of+Computational+Methods+in+Engineering&rft.issn=11343060&rft_id=info:doi/10.1007%2Fs11831-015-9147-y","Design; Software; Analysis; Free software; Informatics; Model; Freeware; Aircraft; Simulation; 33641:Aerospace Product and Parts Manufacturing; Aerial; Mathematics--Computer Applications; Mechanics; Reynolds number; Unmanned aerial vehicle; Unmanned aerial vehicles; Vehicles; Velocity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The rSCA package is efficient in dealing with both continuous and discrete variables, as well as nonlinear relationships between the variables. It divides the sample sets of dependent variables into different subsets (or subclusters) through a series of cutting and merging operations based upon the theory of multivariate analysis of variance (MANOVA). The modeling results are given by a cluster tree, which includes both intermediate and leaf subclusters as well as the flow paths from the root of the tree to each leaf subcluster specified by a series of cutting and merging actions. The rSCA package is a handy and easy-to-use tool and is freely available at http://cran.r-project.org/package=rSCA.

Passive users play a critical role in the adoption and diffusion of OSS, and we need more research to understand their behaviors and motivations. We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.","2015-08","2025-04-25 15:23:18","2025-04-25 15:23:18","","674-706","","8","16","","","","","","","","","","English","","","ABI/INFORM Global","1711618000","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/OBJ/QFcWV?_a=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&_s=Jhwwy9Bc3OJKaqpkwVBZtFS3DlI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Loyalty%2C+Ideology%2C+and+Identification%3A+An+Empirical+Study+of+the+Attitudes+and+Behaviors+of+Passive+Users+of+Open+Source+Software&rft.au=Choi%2C+Namjoo%3BChengalur-Smith%2C+Indushobha%3BNevo%2C+Saggi.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-08-01&rft.volume=16&rft.issue=8&rft.spage=674&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Sociology; Identification; Information systems; Community; Studies; User behavior; Marketing; Virtual communities; Open source; Hypotheses; Open-source software; Consumer behavior; Research; Success; Computers--Information Science And Information Theory; Software development; Loyalty; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; 7100:Market research; Consciousness; Ideology; Usability testing; User","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Likewise, the economic theory of the firm, building on Ronald Coase's (1937) seminal analysis, has become an increasingly important field in economics and management. Despite this resurgence, there is still little connection between the entrepreneurship literature and the literature on the firm, both in academia and in management practice. This book fills this gap by proposing and developing an entrepreneurial theory of the firm that focuses on the connections between entrepreneurship and management. Drawing on insights from Austrian economics, it describes entrepreneurship as judgmental decision made under uncertainty, showing how judgment is the driving force of the market economy and the key to understanding firm performance and organization.","2015-03","2025-04-25 15:23:18","2025-04-25 15:23:18","","239-241","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","1652167838","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/HXZKV?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgYzMjYzMTcyCjE2NTIxNjc4Mzg6DURvY3VtZW50SW1hZ2VCATBSBk9ubGluZVoCRlRiA1BGVGoKMjAxNS8wMy8wMXIKMjAxNS8wMy8zMXoAggElUC0xMDAwMDAxLTEyODYxLUNVU1RPTUVSLW51bGwtMTE0NDQwMpIBBk9ubGluZcoBVE1vemlsbGEvNS4wIChNYWNpbnRvc2g7IEludGVsIE1hYyBPUyBYIDEwLjE1OyBydjoxMzUuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC8xMzUuMNIBElNjaG9sYXJseSBKb3VybmFsc5oCB1ByZVBhaWSqAitPUzpFTVMtTWVkaWFMaW5rc1NlcnZpY2UtZ2V0TWVkaWFVcmxGb3JJdGVtygIGUmV2aWV30gIBWfICAPoCAU6CAwNXZWKKAxxDSUQ6MjAyNTAyMjcwMjA0MDc2MTM6NjY5NzMy&_s=C%2BtbN9CWyXwgb9UqOk4XQ%2FfgFZU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Entrepreneurship+and+Management+Journal&rft.atitle=Nicolai+J.+Foss%2C+Peter+G.+Klein%3A+Organizing+entrepreneurial+judgment%3A+a+new+approach+to+the+firm%3A+Cambridge+and+New+York%3A+Cambridge+University+Press%2C+2012+%28299+pages%29&rft.au=Howden%2C+David.&rft.aulast=Howden&rft.aufirst=David&rft.date=2015-03-01&rft.volume=11&rft.issue=1&rft.spage=239&rft.isbn=&rft.btitle=&rft.title=International+Entrepreneurship+and+Management+Journal&rft.issn=15547191&rft_id=info:doi/10.1007%2Fs11365-013-0276-1","Studies; Business And Economics--Management; Entrepreneurship; Economics; Entrepreneurs; Economic theory; Books; Austrian economics; Company; Court decisions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this, modelling was performed by considering the discrete aspects associated with transport systems with the continuous component of the carbon monoxide emissions from the fleet. The simulation models were constructed with the free and open-source software Ururau. The simulations searched to compare trade-offs of economic and environmental variables, in contrast to what is usually done in these types of systems, such as comparing economic variables with inventory variables. The results indicated that there is no direct relationship of proportionality between, for example, the delivery time and the total emissions produced by trucks.","2015-02","2025-04-25 15:23:18","2025-04-25 15:23:18","","27-42","","1","9","","","","","","","","","","English","","","ABI/INFORM Global","1650380574","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","; ","https://media.proquest.com/media/hms/OBJ/IAMKV?_a=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&_s=nZJkf43ERpwptag6xD22sgRw6fM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Simulation&rft.atitle=Free+and+Open-Source+Software+for+sustainable+analysis+in+logistics+systems+design&rft.au=De+Assis+Rangel%2C+Jo%C3%A3o+Jos%C3%A9%3BCordeiro%2C+Anna+Christine+Azevedo.&rft.aulast=De+Assis+Rangel&rft.aufirst=Jo%C3%A3o&rft.date=2015-02-01&rft.volume=9&rft.issue=1&rft.spage=27&rft.isbn=&rft.btitle=&rft.title=Journal+of+Simulation&rft.issn=17477778&rft_id=info:doi/10.1057%2Fjos.2014.17","Open source software; Computers; Open-source software; Customers; Logistics; Free software; Public domain; Systems design; Simulation; 42311:Automobile and Other Motor Vehicle Merchant Wholesalers; Discrete-event simulation; Greenhouse gas emissions; Suppliers; Supply chain management; Trucks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software--continue to--rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. Trust (i.e. full write-access) is 'backgrounded' by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.[PUBLICATION ABSTRACT]","2014-06","2025-04-25 15:23:18","2025-04-25 15:23:18","","157-169","","2","16","","","","","","","","","","English","","","ABI/INFORM Global","1527288756","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/m0B8V?_a=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&_s=LnBjH3HFlYs2ul1%2B0Dr9IIek9Ks%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Ethics+and+Information+Technology&rft.atitle=From+open-source+software+to+Wikipedia%3A+%27Backgrounding%27+trust+by+collective+monitoring+and+reputation+tracking&rft.au=de+Laat%2C+Paul+B.&rft.aulast=de+Laat&rft.aufirst=Paul&rft.date=2014-06-01&rft.volume=16&rft.issue=2&rft.spage=157&rft.isbn=&rft.btitle=&rft.title=Ethics+and+Information+Technology&rft.issn=13881957&rft_id=info:doi/10.1007%2Fs10676-014-9342-9","Open source software; Philosophy; Community; Social research; Collaboration; Open-source software; Wikipedia; Trust; Social networks; Public domain; Reputations; Reputation; Vandalism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them. Several implications for research and practice, and directions for future research are provided.","2014","2025-04-25 15:23:18","2025-04-25 15:23:18","","260-275","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","1660948775","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/bsfLV?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=%2Fro5Oh0NZVnix0Jp8rf8XWaKix8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+application+profiles+and+development+characteristics+of+library+Open+Source+Software+projects&rft.au=Choi%2C+Namjoo.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2014-04-01&rft.volume=32&rft.issue=2&rft.spage=260&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2FLHT-09-2013-0127","Open source software; Community; Research methodology; Studies; Open source; Libraries; Open-source software; Licenses; Success; Data collection; Software development; Programming languages; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; Library And Information Sciences--Computer Applications; 51921:Libraries and Archives; Academic libraries; Institutional repositories; Archival description; Datasets; Integrated library systems--ILS; Integrated library systems-ILS; Internet resources","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 15:23:18","2025-04-25 15:23:18","","477-512","","4","34","","","","","","","","","","English","","","ABI/INFORM Global","1510748443","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/7E55V?_a=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%3D%3D&_s=czJcKyeF4MxHe1iEAX3BJW6CDu4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=International+Journal+of+Operations+%26+Production+Management&rft.atitle=Risk+of+adopting+mission-critical+OSS+applications%3A+an+interpretive+case+study&rft.au=Poba-Nzaou%2C+Placide%3BRaymond%2C+Louis%3BFabi%2C+Bruno.&rft.aulast=Poba-Nzaou&rft.aufirst=Placide&rft.date=2014-04-01&rft.volume=34&rft.issue=4&rft.spage=477&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Operations+%26+Production+Management&rft.issn=01443577&rft_id=info:doi/10.1108%2FIJOPM-03-2012-0117","Open source software; Information technology; Business And Economics--Management; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we propose and validate two antecedents of organizational investment in internal human capital in the context of OSS adoption. They are (1) firm-specificity of OSS human capital, which denotes the extent to which the internal OSS human capital is strongly tied to the organization and cannot be equally well applied in other organizations, and (2) learning-related scale, which reflects the extent to which the organizational cost of learning OSS can be spread by applying the knowledge gained to other projects and business functions within the organization. Survey data collected from 114 senior Information Technology (IT) managers and professionals indicates that these two factors are positively associated with the investment in cultivating internal OSS human capital.

OSS requires firms to rethink the processes that facilitate value creation and capture. The objective of this paper is to theorise how firms create and capture value from OSS. We derive a model from extant research and refine it through the study of three inter-organisational networks. The findings reveal how a firm's ability to access a value network of complementors is crucial for effective value creation and capture. Two types of networks are evident: a high-density network of familiar partners and a low-density network of multiple, often unfamiliar, partners. Leveraging these networks depends on the level of commitment, volume of knowledge exchange and the alignment of objectives among participant firms. Effective governance is revealed as critical for creating and capturing value within both types of network; and depends on both formal and informal mechanisms.

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 15:23:19","2025-04-25 15:43:35","","28-36","","12","2","","","","","","","","","","English","","","ABI/INFORM Global","1614473125","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/Z92HV?_a=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%3D%3D&_s=ZdYPxuKLXrayO3DF6pRpkY8%2Bmbw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=An+Enterprise+Perspective+on+Customer+Value+Propositions+for+Open+Source+Software&rft.au=Shanker%2C+Aparna.&rft.aulast=Shanker&rft.aufirst=Aparna&rft.date=2012-12-01&rft.volume=2&rft.issue=12&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors suggest that the new paradigm of open innovation may impact a firm's adaptability and responsiveness under conditions of environmental flux. However, extending innovation capacity by opening the innovation process poses major challenges for firms. The aims of this study are to explore the characteristics of open innovation activity and to contemplate the role of strategic flexibility in the design of business models based upon open innovation. Design/methodology/approach - The study draws upon a qualitative research approach through a longitudinal case study in the field of open source software (OSS). The empirical case illustrates how an OSS firm utilizes signals in its environment to flexibly alter its business model. Findings - A business model that embodies open innovation raises dilemmas between open and closed innovation paradigms. However, the authors' case highlights that an ambidextrous approach that combines market orientation with the principles of open innovation increases profitability, shortens time to market through effective market access, and enhances innovation capability. Research limitations/implications - The results have profound implications for industrial marketers, managers, management consultants and business educators. They can use the insights gleaned from this research to guide the development of business models that involve open innovation. The results indicate that firms involved in open innovation need reactive strategic flexibility to cope with the environmental diversity and variability. However, this study analyzes a single case in the field of OSS and one should be cautious when generalizing the findings. Originality/value - This paper improves the understanding of the relationship between flexibility and market orientation. It combines two areas that have previously been discussed separately, i.e. market orientation and open innovation.","2012","2025-04-25 15:23:19","2025-04-25 15:23:19","","1368-1388","","10","46","","","","","","","","","","English","","","ABI/INFORM Global","1048638938","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aSgaU?_a=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%3D%3D&_s=Kt9ntKr6OUvNoPbrVZ%2FKo1MpGrk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Marketing&rft.atitle=Strategic+flexibility+in+open+innovation+-+designing+business+models+for+open+source+software&rft.au=Rajala%2C+Risto%3BWesterlund%2C+Mika%3BM%C3%B6ller%2C+Kristian.&rft.aulast=Rajala&rft.aufirst=Risto&rft.date=2012-10-01&rft.volume=46&rft.issue=10&rft.spage=1368&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Marketing&rft.issn=03090566&rft_id=info:doi/10.1108%2F03090561211248071","Open source software; Qualitative research; Studies; Business And Economics--Marketing And Purchasing; Open source; Open-source software; Competition; Business model; Intellectual property; Business models; Case study; 5240:Software & systems; Public domain; Freeware; Innovations; Open innovation; 9130:Experimental/theoretical; Competitive advantage; Closed innovation; Flexibility; Market orientation; Scholarly publishing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It shows revenue generation factor, cost efficiency factor and growth factor to have a positive influence on the OSS of Indian MFIs. Adjusted impairment loan loss allowance ratio, a portfolio risk factor and average loan size per borrower, a development factor, are seen to have a negative influence on OSS of Indian MFIs. The results thus infer five significant factors that Indian MFI managers must concentrate on to enhance the OSS of their organizations. The authors then discuss how mismanaging these five factors can deviate an MFI from its social goal of poverty alleviation. The crisis in Indian microfinance industry is explored to unveil the dangers involved in mismanagement of these factors. The paper concludes by stating that it is imperative for Indian MFI managers to introspect about their lending and recovery practices, so as to ensure that they manage the factors affecting their OSS, without exploiting the poor clientele.","2012","2025-04-25 15:23:19","2025-04-25 15:23:19","","448","","3","2","","","","","","","","","","English","","","ABI/INFORM Global","1417567674","","","Place: Karachi Publisher: Asian Economic and Social Society","","; ","https://media.proquest.com/media/hms/OBJ/nDvoU?_a=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%3D%3D&_s=hVAYAXGCnKFve08NUURz%2BdlefTk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Asian+Economic+and+Financial+Review&rft.atitle=Dangers+in+Mismanaging+the+Factors+Affecting+the+Operational+Self-Sustainability+%28OSS%29+of+Indian+Microfinance+Institutions+%28MFIs%29+-+An+Exploration+into+Indian+Microfinance+Crisis&rft.au=Nadiya%2C+M%3BOlivares-Polanco%2C+Francisco%3BRamanan%2C+T+Radha.&rft.aulast=Nadiya&rft.aufirst=M&rft.date=2012-04-01&rft.volume=2&rft.issue=3&rft.spage=448&rft.isbn=&rft.btitle=&rft.title=Asian+Economic+and+Financial+Review&rft.issn=23052147&rft_id=info:doi/","India; Business And Economics; Trends; Sustainability; Costs; Literature reviews; Poverty; Graduate students; Growth factors; Interest rates; Loan; Mechanical engineering; Microfinance; Microfinance Crisis; Mismanagement; Multiple regression analysis; Social goals","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One way federal procurement regulations advance public interest is by seeking ""optimal"" or ""best"" value in purchasing decisions. For each purchasing option, one determines the net benefit, which is a discounted difference between all present and future costs and benefits. This study considers the implications of pricing thresholds on government procurement processes in light of the advent and increasing use of free enterprise software. Researchers conducted a randomized Web-based survey of 138 government procurement officials (IT managers). The results indicate that free software may provide procurement officials with an opportunity to bypass institutionalized procurement best practices. The fieldwork indicates that IT purchases made through a full procurement process may enjoy a higher level of satisfaction than purchases of paid and free software acquired with limited or no procurement process review.","2012","2025-04-25 15:23:20","2025-04-25 15:23:20","","197-226,230","","2","41","","","","","","","","","","English","","","ABI/INFORM Global","1017544868","","","Place: Chicago Publisher: American Bar Association","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Public+Contract+Law+Journal&rft.atitle=GOVERNMENT+IT+PROCUREMENT+PROCESSES+AND+FREE+SOFTWARE&rft.au=Iansiti%2C+Marco.&rft.aulast=Iansiti&rft.aufirst=Marco&rft.date=2012-01-01&rft.volume=41&rft.issue=2&rft.spage=197&rft.isbn=&rft.btitle=&rft.title=Public+Contract+Law+Journal&rft.issn=00333441&rft_id=info:doi/","Law; Decision making; Information technology; Studies; Software; Free software; Government; Costs; Business models; 9130:Experiment/theoretical treatment; Freeware; United States--US; 9190:United States; 9550:Public sector; 5120:Purchasing; 5220:Information technology management; Best practice; Budgets; Government procurement; Government purchasing; Neutrality; Procurement; Public interest; Purchase options; User satisfaction","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on information gathered from the open-source website (www.osor.eu) we have built a database of open-source public interventions, establishing that public support in Europe for open-source software is usually reflected in direct adoption by a public partner or in positive statements about such adoption. Our analysis suggests that a serious analysis of the rationality, motivations and consequences of such public interventions involves a careful examination of the various roles of the public powers and the various categories of software involved. We provide empirical evidence that FOSS support is stronger in countries (i) where e-government services are more largely available, and (ii) where the domestic software industry is lagging behind. This evidence supports common views among FOSS advocates.","2011","2025-04-25 15:23:20","2025-04-25 15:23:20","","89-108","","136","","","","","","","","","","","English","","","ABI/INFORM Global","1586117312","","","Place: Brussels Publisher: Editions De Boeck Superieur","","; ","https://media.proquest.com/media/hms/OBJ/sGIGV?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgYzODY2MTQyCjE1ODYxMTczMTI6DURvY3VtZW50SW1hZ2VCATBSBk9ubGluZVoCRlRiA1BGVGoKMjAxMS8xMC8wMXIKMjAxMS8xMi8zMXoAggElUC0xMDAwMDAxLTEyODYxLUNVU1RPTUVSLW51bGwtMTE0NDQwMpIBBk9ubGluZcoBVE1vemlsbGEvNS4wIChNYWNpbnRvc2g7IEludGVsIE1hYyBPUyBYIDEwLjE1OyBydjoxMzUuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC8xMzUuMNIBElNjaG9sYXJseSBKb3VybmFsc5oCB1ByZVBhaWSqAitPUzpFTVMtTWVkaWFMaW5rc1NlcnZpY2UtZ2V0TWVkaWFVcmxGb3JJdGVtygIHRmVhdHVyZdICAVnyAgD6AgFOggMDV2ViigMcQ0lEOjIwMjUwMjI3MDIwNDA3NjEzOjY2OTczMg%3D%3D&_s=k%2B39lyKXr8S7K4tL52QHDuOJqjQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revue+d%27%C3%89conomie+Industrielle&rft.atitle=PUBLIC+INTERVENTION+FOR+FREE%2FOPEN+SOURCE+SOFTWARE&rft.au=Comino%2C+Stefano%3BManenti%2C+Fabio+M%3BRossi%2C+Alessandro.&rft.aulast=Comino&rft.aufirst=Stefano&rft.date=2011-10-01&rft.volume=&rft.issue=136&rft.spage=89&rft.isbn=&rft.btitle=&rft.title=Revue+d%27%C3%89conomie+Industrielle&rft.issn=01543229&rft_id=info:doi/","Open source software; Information technology; Open source; Software; Public policy; Intellectual property; Electronic government; 5240:Software & systems; Impact analysis; Public domain; 51321:Software Publishers; Software industry; Innovations; Code reuse; E-government; Public sector; 9175:Western Europe; 1130:Economic theory; Free and open-source software; Cost control; Business And Economics--Production of Goods And Services; 92114:Executive and Legislative Offices, Combined; Public administration; France; Computer based modeling; Intervention","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We argue to the contrary that contemporary business and economic trends definitively demonstrate the financial viability of an economy based on free software. But the argument for free software derives its true normative weight from social justice considerations: the evaluation of the basis for a software economy should be guided by consideration of the social and cultural states which are the ultimate goals of any economic arrangement. That is, the software economy should be evaluated in light of its ability to provide justice.

However, these have had less influence in China thus far, though there has been a rapid growth of free/open source software in China. This article argues that China now needs a different voice against the IPR dogma and should make a contribution to the international effort against intellectual monopoly, and the software industry could be where to start. On one hand, China should take further measures to promote the development of free/open source software. On the other hand, China needs to scrutinize and reform relevant economic and legal systems and adjust strategy for international negotiations, strengthening antitrust enforcement against software monopoly and taking a tough stance against software patents in international community.

Felin and N. J. Foss, 'The Endogenous Origins of Experience, Routines and Organizational Capabilities: The Poverty of Stimulus', published by the Journal of Institutional Economics. Although valuable points are raised, the assessment is largely off target because it is fixated on the implausible view that the literature assessed is strongly shaped by the tradition of behavioral psychology (B. F. Skinner and others). At the same time, important portions of the routines and capabilities literature that are highly relevant to the authors' substantive concerns, and which are plainly inconsistent with the main interpretive claim, are not considered.

Felin and N. J. Foss, 'The Endogenous Origins of Experience, Routines and Organizational Capabilities: The Poverty of Stimulus', published by the Journal of Institutional Economics. The emphasis here is on practice-based theories of organizational routines that are grounded in close, ethnographic observation of real routines. While this literature may be unfamiliar to some readers, it is relevant here because it specifically contradicts the core assertions made by Felin and Foss. Further, this literature provides a clear theoretical foundation for subsequent research on problems such as stability and change in routines, the nature of capabilities and dynamic capabilities, and complex ecologies of routines.

We present occupancy and patient scheduling models to help address these challenges. These patient flow models can be used to explore the relationship between procedure scheduling practices and the resulting occupancy on inpatient obstetrical units such as labor and delivery and postpartum. The models capture numerous important characteristics of inpatient obstetrical patient flow such as time of day and day of week dependent arrivals and length of stay, multiple patient types and clinical interventions, and multiple patient care units with inter-unit patient transfers. We have used these models in several projects at different hospitals involving design of procedure scheduling templates and analysis of inpatient obstetrical capacity. In the development of these models, we made heavy use of open source software tools and have released the entire project as a free and open source model and software toolkit.[PUBLICATION ABSTRACT]","2011-03","2025-04-25 15:23:20","2025-04-25 15:23:20","","56-73","","1","14","","","","","","","","","","English","","","ABI/INFORM Global","848542518; 20978855","","","Place: New york Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/uZM9U?_a=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%3D%3D&_s=JDm8z6cfbbW3FS8G2S9pPjburKU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Health+Care+Management+Science&rft.atitle=An+open+source+software+project+for+obstetrical+procedure+scheduling+and+occupancy+analysis&rft.au=Isken%2C+Mark+W%3BWard%2C+Timothy+J%3BLittig%2C+Steven+J.&rft.aulast=Isken&rft.aufirst=Mark&rft.date=2011-03-01&rft.volume=14&rft.issue=1&rft.spage=56&rft.isbn=&rft.btitle=&rft.title=Health+Care+Management+Science&rft.issn=13869620&rft_id=info:doi/10.1007%2Fs10729-010-9141-8","Open source software; Female; Studies; Software engineering; Open-source software; Patients; Humans; Hospitals; 5240:Software & systems; Public domain; 9130:Experimental/theoretical; 9175:Western Europe; International; 62211:General Medical and Surgical Hospitals; 8320:Health care industry; Appointments & Schedules; Births; Cesarean section; Cesarean Section -- statistics & numerical data; Efficiency, Organizational; Health care industry; Health Facilities And Administration; Induced labor; Labor, Induced -- statistics & numerical data; Length of stay; Obstetrics; Obstetrics & Gynecology Department, Hospital -- organization & administration; Postpartum period; Pregnancy; Process Assessment (Health Care) -- statistics & numerical data; Scheduling; Software Design; Time Factors; Vagina; Workforce planning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Adoption studies represent a particularly promising area for information system researchers to investigate the relationship between the specific properties of FLOSS and the processes of implementation and use. The goal of this article is to contribute to this field of research by discussing a former multi-targeted research agenda and by defining an empirically grounded framework for studying FLOSS adoption, drawing on the outcomes of an exploratory multiple case study involving sixteen Italian public administrations.","2011","2025-04-25 15:23:21","2025-04-25 15:23:21","","15","","","29","","","","","","","","","","English","","","ABI/INFORM Global","2500531784","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/MUCVI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=pMcJJjm%2FcpnVf3adQhdAWxHNR%2BQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Exploring+the+Interplay+Between+FLOSS+Adoption+and+Organizational+Innovation&rft.au=Spagnoletti%2C+Paolo%3BFederici%2C+Tommaso.&rft.aulast=Spagnoletti&rft.aufirst=Paolo&rft.date=2011-01-01&rft.volume=29&rft.issue=&rft.spage=15&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.02915","Innovation; Open source; Computers--Information Science And Information Theory; Organizational change; Organizational behavior; Adoption; Freeware; Innovations; public sector; Floss; Italy; Adoption study; FLOSS adoption; multiple case study; organizational innovation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the most interesting results, our multivariate analyses of developers' code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early-as the ""credible promise"" in OSS-leads to increased reuse. Finally, we identify developers' interest in tackling difficult technical challenges as detrimental to efficient reuse-based innovation. Beyond OSS, we discuss the relevance of our findings for companies developing software and for the receiving side of open innovation processes, in general.

Examining what motivates participants in OSS projects and how to enhance the effects of motivations has received increased attention in recent years. This study is prompted by the significant but detail-lacking examination of differential effects of various types of extrinsic motivations on participants' task effort in OSS projects and their interaction effects with participants' psychological states. Drawing upon self-determination theory, we establish four types of extrinsic motivations in OSS communities (i.e., external, introjected, identified, and integrated motivation) and investigate how these types affect task effort differently. Also, integrating self-determination theory with affective event theory, we study how satisfaction of needs for competence, autonomy, and relatedness moderates the relationships between extrinsic motivations and task effort. The research model is largely supported by data from 250 participants in various OSS projects. Theoretical contribution and practical implications are discussed.

Project communities and customer pipelines are not the same thing, although some participants belong to both groups. This creates confusion in the business and tension with the community. F/LOSS communities have been on the rise for the past two decades. Companies began to form around F/LOSS projects in the early 1990s, with some creating their own F/LOSS projects and some wrapping themselves around existing projects. This has created tension between company managers who are trying to earn profits from software that is ""available for free,"" and from developers in communities that do not necessarily want to create software for someone else's corporate gain. This happens regardless of whether the company created the F/LOSS-licensed project itself, or participates in external communities around other projects, or both. This article demonstrates that separating the concepts of community and customer, and of project and product, allows a business to manage clearly both challenges of developing an engaged community and maximizing profits.","2010-10","2025-04-25 15:23:21","2025-04-25 15:23:21","","5-13","","","","","","","","","","","","","English","","","ABI/INFORM Global","1695042597","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/gCfiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk1MDQyNTk3Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTAvMTAvMDFyCjIwMTAvMTAvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=iIQy0fuCTuZFWuw6MqauZu0jZFs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=Differentiating+Community+from+Customers+in+an+F%2FLOSS+Business&rft.au=Aslett%2C+Matthew%3BWalli%2C+Stephen.&rft.aulast=Aslett&rft.aufirst=Matthew&rft.date=2010-10-01&rft.volume=&rft.issue=&rft.spage=&rft.isbn=&rft.btitle=&rft.title=&rft.issn=&rft_id=info:doi/","Open source software; Community; Canada; Business And Economics; Collaboration; Marketing; Customers; Business; Internet; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Project; Research & development--R&D; Loss; 9172:Canada; Customer relationship management; 2400:Public relations; Customer; Product; Profit maximization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

Yet, in 1992, everyone agreed there was still much work to be done. Even today, you still strive for a desktop and server operating system, with all relevant applications, that grants complete software freedom. Hardware companies are not the only entity interested in phone operating systems. Google, ever-focused on routing human eyes to its controlled advertising, realizes that even more eyes will be on mobile computing platforms in the future. With this goal in mind, Google released the Android/Linux system, now available on a variety of phones in varying degrees of software freedom. Seeking software freedom on mobile devices will remain a complicated endeavour for some time. Your community should utilize the F/LOSS releases from companies, but should not forget that, until viable community forks exist, software freedom on these devices exists at the whim of these companies.","2010-03","2025-04-25 15:23:21","2025-04-25 15:23:21","","32-36","","","","","","","","","","","","","English","","","ABI/INFORM Global","1695041925","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/dheiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk1MDQxOTI1Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTAvMDMvMDFyCjIwMTAvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=dEhJVILFVrKGA02M%2F7vQfGgUbsE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=THE+STATE+OF+FREE+SOFTWARE+IN+MOBILE+DEVICES&rft.au=Kuhn%2C+Bradley+M.&rft.aulast=Kuhn&rft.aufirst=Bradley&rft.date=2010-03-01&rft.volume=&rft.issue=&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Computers; Canada; Business And Economics; Software; Libraries; Linux; Operating systems; Free software; Computer industry; 5240:Software & systems; Freeware; Proprietary; Smartphones; 33411:Computer and Peripheral Equipment Manufacturing; 9172:Canada; 51921:Libraries and Archives; Android; Advertising; Mobile; Mobile device","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The participants feel that they belong to the community and many also feel that they are recognised as part of the community.

Guest Editors: Wei Jiang and Anurag Agarwal and Regular papers This paper develops tests and validates a model for the antecedents of open source software (OSS) defects, using Data and Text Mining. The public archives of OSS projects are used to access historical data on over 5,000 active and mature OSS projects. Using domain knowledge and exploratory analysis, a wide range of variables is identified from the process, product, resource, and end-user characteristics of a project to ensure that the model is robust and considers all aspects of the system. Multiple Data Mining techniques are used to refine the model and data is enriched by the use of Text Mining for knowledge discovery from qualitative information. The study demonstrates the suitability of Data Mining and Text Mining for model building. Results indicate that project type, end-user activity, process quality, team size and project popularity have a significant impact on the defect density of operational OSS projects. Since many organizations, both for profit and not for profit, are beginning to use Open Source Software as an economic alternative to commercial software, these results can be used in the process of deciding what software can be reasonably maintained by an organization.

The purpose of this paper is to describe the software architecture. Design/methodology/approach - The DEM chosen uses position, orientation, velocity and angular velocity as independent variables of simulated particles which are subject to explicit leapfrog time-integration scheme (Lagrangian method). The three-dimensional dynamics equations based on the classical Newtonian approach for the second law of motion are used. The track of forces and moments acting on each particle is kept at every time step. Contact forces depend on the particle geometry overlap and material properties. The normal, tangential and moment components of interaction force are included. Findings - An effort is undertaken to extract the underlying object oriented abstractions in the DEM. These abstractions are implemented in C++, conform to object oriented design principles and use design patterns. Based on that, a software framework is developed in which the abstractions provide the interface where the modelling methods can be plugged-in. Originality/value - The resulting YADE-OPEN DEM framework is designed in a generic way which provides great flexibility when adding new scientific simulation code. Some of the advantages are that numerous simulation methods can be coupled within the same framework while plug-ins can import data from other software. In addition, this promotes code improvement through open-source development and allows feedback from the community. However implementing such models requires that one adheres to the framework design and the YADE framework is a new emerging software. To download the software see http : //yade.wikia.com webpage.

OSS/FS alternatives complicate an already complex information goods market plagued by piracy concerns. Although producer perspectives on software pricing and piracy controls have been addressed extensively, consumers' perspective and willingness to pay for commercial software is not very well understood. This paper empirically determines willingness to pay for a leading commercial software application (Microsoft Office) in the presence of an OSS/FS alternative. A contingent valuation approach is used to elicit willingness to pay for the application. The research design employs a 2 × 2 × 2 experiment to investigate the impact of preventive control, deterrence control, and OSS/FS alternative. The results indicate that the availability of an OSS/FS alternative has little impact on willingness to pay for Microsoft Office. However, piracy controls significantly increase willingness to pay for Microsoft Office, even in the presence of OSS/FS alternatives.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.

A number of highly influential papers have argued that the self-fulfilling nature of (even false) theories provides the underlying mechanism through which economics has adversely shaped not just social science but also management practice and individual behavior. We question these arguments and argue that there are important boundary conditions to theories falsely fulfilling themselves, boundary conditions that have hitherto been unexplored in organizational research, and boundary conditions that question the underlying premises used by organizational scholars and social scientists to attack economics. We specifically build on highly relevant findings from social psychology, philosophy, and organizational economics to show how (1) objective reality and (2) human nature provide two important boundary conditions for theories (falsely or otherwise) fulfilling themselves. We also defend organizational economics, specifically the use of high-powered incentives in organizations, and argue that self-interest (rightly understood) facilitates in creating beneficial individual and collective and societal outcomes.

Their initial experiences applying the tool in an R&D organization indicate that it helps establish a systematic project monitoring and control process by supporting or automating tasks. In this way, it presents an open, flexible, and free tool-integration solution for project management, illustrating that open-source tools might be appealing, especially for small organizations.

This is in spite of: 1. the rise in commercial development and support for F/LOSS, 2. the goal of most F/LOSS projects to incorporate improvements, which is actually a form of financial gain, 3. official definitions of ""commercial item"" that include F/LOSS, and 4. F/LOSS licenses and projects that clearly approve of commercial support. In reality there are two types of commercial software: proprietary software and F/LOSS. This paper provides examples for each of the four points mentioned, briefly notes some alternative terms, and ends with some conclusions, explaining why it is important to understand that F/LOSS software is almost always commercial.","2009-02","2025-04-25 15:23:22","2025-04-25 15:23:22","","25-33","","","","","","","","","","","","","English","","","ABI/INFORM Global","1695041145","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/SyeiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk1MDQxMTQ1Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDkvMDIvMDFyCjIwMDkvMDIvMjh6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Z%2FONeSv%2BFIZIROjIrDVn3%2F5s6x0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=F%2FLOSS+IS+COMMERCIAL+SOFTWARE&rft.au=Wheeler%2C+David+A.&rft.aulast=Wheeler&rft.aufirst=David&rft.date=2009-02-01&rft.volume=&rft.issue=&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Business And Economics; Open source; Software; Licenses; Linux; Business models; 5240:Software & systems; Public domain; United States--US; 9190:United States; 2310:Planning; Loss; Government purchasing; Nonprofit organizations; Commercialization; Royalties; Commercial; Commercial software; Investments; Proprietary software","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-25 15:23:22","2025-04-25 15:23:22","","449-462","","5","16","","","","","","","","","","English","","","ABI/INFORM Global","212365312","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/b6OaT?_a=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%3D%3D&_s=SoMHSxzncc%2FFgWIjigCYfocNCzU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Management+%26+Computer+Security&rft.atitle=Evaluating+the+performance+of+open+source+software+projects+using+data+envelopment+analysis&rft.au=Wray%2C+Barry%3BMathieu%2C+Richard.&rft.aulast=Wray&rft.aufirst=Barry&rft.date=2008-10-20&rft.volume=16&rft.issue=5&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Information+Management+%26+Computer+Security&rft.issn=09685227&rft_id=info:doi/10.1108%2F09685220810920530","Open source software; Studies; Productivity; Business And Economics--Management; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, when one plans to study the adequacy of open source software (OSS), it is necessary to have a method of qualification and selection adapted to the characteristics of this type of software and to precisely examine the constraints and risks specific to OSS. Since the open source field has a very broad scope, it is also necessary to use a qualification method that differentiates between numerous candidates to meet technical, functional and strategic requirements. The vast amount of available OSS software requires a methodology to allow for the evaluation of potential candidates to meet business requirements. The QSOS methodology allows for an iterative needs analysis for gauging the technical, functional, and strategic capabilities of OSS products.","2008-05","2025-04-25 15:23:22","2025-04-25 15:23:22","","10-16","","","","","","","","","","","","","English","","","ABI/INFORM Global","1694724606","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/NteiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk0NzI0NjA2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDgvMDUvMDFyCjIwMDgvMDUvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Nzc1rGWsZxtiJvHZ4KTJ%2FI3GuNU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=QUALIFICATION+%26amp%3B+SELECTION+OF+OSS&rft.au=Semeteys%2C+Rapha%C3%ABl.&rft.aulast=Semeteys&rft.aufirst=Rapha%C3%ABl&rft.date=2008-05-01&rft.volume=&rft.issue=&rft.spage=10&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Business And Economics; Open-source software; Licenses; Risk; Strategy; Qualifications; ISO standards; 5240:Software & systems; United States--US; 9190:United States; Component-based software engineering; Need; Qualification; Selection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Employees belonging to the open source movement often advocate the use of open source software within their organization. Hence, their belief in the underlying open source software ideology may influence the decision making on the adoption of open source software. This may result in an ideological—rather than pragmatic—decision. A recent study has shown that American organizations are quite pragmatic in their adoption decision. We argue that there may be circumstances in which there is more opportunity for ideological behavior. We therefore investigated the organizational adoption decision in Belgian organizations. Our results indicate that most organizations are pragmatic in their decision making. However, we have found evidence that suggests that the influence of ideology should not be completely disregarded in small organizations.","2008","2025-04-25 15:23:22","2025-04-25 15:23:22","","58-72","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954642502","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/XD6YX?_a=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%3D%3D&_s=ww6xE5v2UXxv23OVeBXco526Ds4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=The+Impact+of+Ideology+on+the+Organizational+Adoption+of+Open+Source+Software&rft.au=Ven%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Ven&rft.aufirst=Kris&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=58&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040103","Open source software; Organizations; Decision making; Open source; Software; Open-source software; Adoption; Computers--Data Base Management; Ideology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We begin by measuring the digital divide in these very different regions of the world. Our research demonstrates, both quantitatively and qualitatively, how the digital divide places populations in both regions at a disadvantage. Next we examine the role of these technologies in bridging the digital divide along three complementary dimensions. First, we show that both affordable technology and sound policy are necessary for digital inclusion. Second, we look at how these two technologies are extended, integrated, and customized in information and communication technology (ICT) solutions that are both creative and effective.

Qualitative data were collected over a four year period using a virtual ethnography in a study of free and open source software development and, in particular, a study of a free software community, GNUenterprise, located at www.gnuenterprise.org, which has the goal of developing a free enterprise resource planning software system. It is concluded that the ideology of the free software movement continues to be one of the factors which mobilize people to contribute to free and open source software development. This movement represents a new type of computerization movement which promotes the investment of time in learning a new software development process instead of investment of money in the acquisition and use of new technology. The research findings are limited by a detailed study of only one free software development project. This paper is of significance to software developers and managers of firms who wish to incorporate free and open source software into their companies. This research presents an original conceptual diagram and framework for how computerization movements have emerged into an occupational community.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-25 15:23:23","2025-04-25 15:23:23","","142-156","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","211770348","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aQ4UT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNjE2NDIJMjExNzcwMzQ4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDgvMDEvMDFyCjIwMDgvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=SAswoqID8hrBd8RAEe40nEM7N%2FU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Innovation+Management&rft.atitle=Online+innovation%3A+the+case+of+open+source+software+development&rft.au=Vujovic%2C+Sladjana%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=Vujovic&rft.aufirst=Sladjana&rft.date=2008-01-01&rft.volume=11&rft.issue=1&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Innovation+Management&rft.issn=14601060&rft_id=info:doi/10.1108%2F14601060810845268","Open source software; Innovation; Communication; Information technology; Studies; Business And Economics--Management; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Public domain; Technological change; Innovations; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This shift is not only redefining the software industry but also the way we teach and learn in our software engineering (SE) courses. But for many universities F/OSS is seen as an optional low cost technology to support the IT infrastructure and administrational duties. Few see F/OSS as an opportunity for students to learn the SE concepts and skills we teach. Furthermore, it is still an open question as to whether the F/OSS methodology can be effectively used to teach SE courses within the formally structured curriculum in most universities. This paper discusses F/OSS projects as bazaars of learning that offer a meaningful learning context. The discussion is centered on a pilot study in which students were involved in software testing in F/OSS projects. We present the teaching and learning framework we used in the pilot study and report on our experiences, lessons learned, and some practical problems we encountered. Our grading and evaluation approach show that the students did relatively well as bug hunters and reporters. Results from two online surveys indicate that students are motivated in participating in software testing in the bazaar, and they are willing to participate in project activities long after their graduation. The study reveals one possible way SE educators can teach and integrate F/OSS into their formal curricular structure.

On the negative side, this increasing dependence on computers has resulted in research that has become increasingly difficult to replicate. In this paper, we propose some basic standards to improve the production and reporting of computational results in economics for the purpose of accuracy and reproducibility. In particular, we make recommendations on four aspects of the process: computational practice, published reporting, supporting documentation, and visualization. Also, we reflect on current developments in the practice of computing and visualization, such as integrated dynamic electronic documents, distributed computing systems, open source software, and their potential usefulness in making computational and empirical research in economics more easily reproducible.

A case study is presented in a technological undergraduate course of a Federal Center of Technological Education. The study case presents the research and the development of an innovative model of management for the course. Finally, the authors defend that this model can be applied to other organizations based upon a series of results and conclusions.

Three projects were selected from SourceForge.net in terms of their similarities as well as their differences. Monthly data were extracted from the bug tracking systems in order to achieve a longitudinal view of the interaction pattern of each project. Social network analysis was used to generate the indices of social structure. The finding suggests that the interaction pattern of OSS projects evolves from a single hub at the beginning to a core/periphery model as the projects move forward.","2007","2025-04-25 15:23:23","2025-04-25 15:23:23","","25-40","","2","18","","","","","","","","","","English","","","ABI/INFORM Global","2954642984","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/vD6YX?_a=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%3D%3D&_s=YpJkHh7RL5XJbFdZMoXj0WZubjg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Social+Network+Structures+in+Open+Source+Software+Development+Teams&rft.au=Long%2C+Yuan%3BSiau%2C+Keng.&rft.aulast=Long&rft.aufirst=Yuan&rft.date=2007-01-01&rft.volume=18&rft.issue=2&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2007040102","Open source software; Social network analysis; Open source; Open-source software; Network analysis; Teams; Social networks; Software development; Computers--Data Base Management; Social network; Tracking systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We argue for the importance of studying open source software use and propose a framework to guide research in this area. The framework describes four main areas of investigation: the creation of OSS user communities, their characteristics, their contributions and how they change. For each area of the framework, we suggest several research questions that deserve attention.","2007","2025-04-25 15:23:23","2025-04-25 15:23:23","","68-80","","1","20","","","","","","","","","","English","","","ABI/INFORM Global","2931884467","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/bEmQX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=klft04rXJ8JdsnSiMgYFKEvM39o%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Resources+Management+Journal&rft.atitle=Beyond+Development%3A+A+Research+Agenda+for+Investigating+Open+Source+Software+User+Communities&rft.au=Jin%2C+Leigh%3BRobey%2C+Daniel%3BBoudreau%2C+Marie-Claude.&rft.aulast=Jin&rft.aufirst=Leigh&rft.date=2007-01-01&rft.volume=20&rft.issue=1&rft.spage=68&rft.isbn=&rft.btitle=&rft.title=Information+Resources+Management+Journal&rft.issn=10401628&rft_id=info:doi/10.4018%2Firmj.2007010105","Open source software; Information systems; Business And Economics--Management; Open source; Open-source software; Software development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Academics and practitioners have offered several suggestions to improve the usability of such software. However, a realistic assessment of OSS projects, specifically the motivations of OSS developers and their attitude toward software usability, lack of user feedback, and absence of usability experts in OSS projects, leads to the conclusion that strategies to improve OSS usability are unlikely to succeed anytime soon. The only exceptions will be OSS which enjoy sufficient financial support from individuals and organizations, and software that were developed by commercial software producers and later released under an open source license.","2007","2025-04-25 15:23:24","2025-04-25 15:23:24","","25","","","20","","","","","","","","","","English","","","ABI/INFORM Global","2500547773","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/jgCVI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Le83Zx8YqbLXdrH3QZy1qQV5GyE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Waiting+for+Usable+Open+Source+Software%3F+Don%27t+Hold+Your+Breath%21&rft.au=Sen%2C+Ravi.&rft.aulast=Sen&rft.aufirst=Ravi&rft.date=2007-01-01&rft.volume=20&rft.issue=&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.02025","Open source software; Open source; Software engineering; Software; Open-source software; Usability; Computers--Information Science And Information Theory; Software development; Software quality; Public domain","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper develops and tests a model of the impacts of license restrictiveness and organizational sponsorship on two indicators of success: user interest in, and development activity on, open source software development projects. Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.

Service discovery is an essential mechanism to achieve this goal. Driven primarily by the OSS requirements, this paper proposes a new service discovery methodology for next generation OSS -- model-based service discovery (MBSD). MBSD takes advantage of the OMG MDA (model-driven architecture) technology. The system architecture of MBSD and its operation and implementation are presented. The proposed methodology is briefly validated through an OSS scenario.

However, he defines knowledge in terms that make it amenable to a certain form of economic analysis, and thus overlooks potential insights from other perspectives. As soon as sociological issues are taken into account, the concept of knowledge has to be broadened, and also his theory of control. In particular, the role of the community or group in knowledge creation has to be allowed for. Although sociological and economics-based explanations are sometimes presented as conflicting alternatives, there is no inevitable reason why sociological and economics-based perspectives cannot be integrated in a common framework.","2006","2025-04-25 15:23:25","2025-04-25 15:23:25","","21-27","","1","10","","","","","","","","","","English","","","ABI/INFORM Global","200688856","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/MHKxS?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNTk1NzIJMjAwNjg4ODU2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=5cofK6cscbNkfIthyEbHHjAiWyU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+%26+Governance&rft.atitle=Knowledge+in+the+Theory+of+the+Firm+and+MNC%3A+Asset+or+Action%3F+A+Commentary+on+Foss+N.+%26quot%3BKnowledge+and+Organisation+in+the+Theory+of+the+MNC%26quot%3B&rft.au=Barnard%2C+Helena%3BCantwell%2C+John.&rft.aulast=Barnard&rft.aufirst=Helena&rft.date=2006-03-01&rft.volume=10&rft.issue=1&rft.spage=21&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+%26+Governance&rft.issn=13853457&rft_id=info:doi/10.1007%2Fs10997-005-3546-7","Sociology; Studies; Knowledge; Knowledge management; Knowledge economy; Economics; Control theory; 2500:Organizational behavior; 9130:Experimental/theoretical; 1130:Economic theory; Business And Economics--Banking And Finance; Economic theory; Multinational corporations; 1220:Social trends & culture; Communities of practice; Theory of the firm","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some governments have actually begun to procure FLOSS, whereas others have channeled public funds to large-scale FLOSS projects. This study demonstrates both the benefits and the risks of government policy favoring FLOSS from the perspective of economics, technology, and politics, and to further analyze whether these same policy goals can be achieved through government support of FLOSS. The most fundamental argument of the study is that, in lending its support to FLOSS, the difference between a government user and a business user is that the government should take into account society's long-term interests, not merely its own interests as a consumer.[PUBLICATION ABSTRACT]","2006","2025-04-25 15:23:25","2025-04-25 15:23:25","","113-141","","4","18","","","","","","","","","","English","","","ABI/INFORM Global","821676609","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/bX87U?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU3NTkzNzIJODIxNjc2NjA5Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=YM1BXdESXYlFxwNLnjdbPXVMORU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Government+policy+toward+open+source+software%3A+The+puzzles+of+neutrality+and+competition&rft.au=Lee%2C+Jyh-an.&rft.aulast=Lee&rft.aufirst=Jyh-an&rft.date=2006-01-01&rft.volume=18&rft.issue=4&rft.spage=113&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-006-1007-5","Open source software; Sociology; Open source; Open-source software; Public policy; Open data; Open innovation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We begin by answering perhaps the most basic question: what is the social structure of these teams? We conducted social network analyses of bug-fixing interactions from three repositories: Sourceforge, GNU Savannah and Apache Bugzilla. We find that some OSS teams are highly centralized, but contrary to expectation, others are not. Projects are mostly quite hierarchical on four measures of hierarchy, consistent with past research but contrary to the naive image of these projects. Furthermore, we find that the level of centralization is negatively correlated with project size, suggesting that larger projects become more modular, or possibly that becoming more modular is a key to growth. The paper makes a further methodological contribution by identifying appropriate analysis approaches for interaction data. We conclude by sketching directions for future research.[PUBLICATION ABSTRACT]","2006","2025-04-25 15:23:25","2025-04-25 15:23:25","","65-85","","4","18","","","","","","","","","","English","","","ABI/INFORM Global","821676606","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/wU87U?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU3NTkzNzIJODIxNjc2NjA2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=cZbfxGayBRxpOd3OqV05XabWcnA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Hierarchy+and+centralization+in+free+and+open+source+software+team+communications&rft.au=Crowston%2C+Kevin%3BHowison%2C+James.&rft.aulast=Crowston&rft.aufirst=Kevin&rft.date=2006-01-01&rft.volume=18&rft.issue=4&rft.spage=65&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-006-1004-8","Open source software; Remote work; Sociology; Social network analysis; Open source; Software; Open-source software; Hierarchy; Public domain; Centralisation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The paper briefly traces the economic significance of the software industry and the dominance in packaged software of the large US publishers, the phenomena of natural monopolies building in software packages, and the need for different industry structure for Europe, as it exhibits a small to medium-sized enterprise (SME) and system integrator structure. It then examines the balancing affects of OSS. The paper also addresses the role that poor software plays in creating new costs or externalities for its users when it fails, contrasting the robustness of open source in defect repair. The paper finds that the way forward in economic terms for Europe may well be to follow and encourage OSS for reasons of creating a strong software industry and for a counterbalance to current monopolistic trends. The paper's findings emphasise the need for investment, education and encouragement in OSS, by both the public and private sectors, to build a strong knowledge-based society in Europe. The paper introduces the ideas of the basic economic mechanisms of volume sales of software as a good, with analysis of the industry impacts of confluence of the network effect coupled with the law of increasing returns with volume to drive monopolistic positions in the proprietary software package industry.","2006","2025-04-25 15:23:25","2025-04-25 15:23:25","","12-31","","3","8","","","","","","","","","","English","","","ABI/INFORM Global","275029739","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/NWdDT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0MjU0MTIJMjc1MDI5NzM5Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=raMMlF7qwlgTC1gQ%2B98jvK4%2BZWw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Info+%3A+the+Journal+of+Policy%2C+Regulation+and+Strategy+for+Telecommunications%2C+Information+and+Media&rft.atitle=The+rain+forest+and+the+rock+garden%3A+the+economic+impacts+of+open+source+software&rft.au=Forge%2C+Simon.&rft.aulast=Forge&rft.aufirst=Simon&rft.date=2006-01-01&rft.volume=8&rft.issue=3&rft.spage=12&rft.isbn=&rft.btitle=&rft.title=Info+%3A+the+Journal+of+Policy%2C+Regulation+and+Strategy+for+Telecommunications%2C+Information+and+Media&rft.issn=14636697&rft_id=info:doi/10.1108%2F14636690610664633","Open source software; Productivity; Open source; Open-source software; Software packages; Communications; Economics; 5240:Software & systems; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Economic; Software industry; 9175:Western Europe; Network effect; United Kingdom--UK; Employees; Employment; Economic development; 1110:Economic conditions & forecasts; Consumer goods; Economic growth; Economic impact; Global economy; Gross Domestic Product--GDP; Rainforest; Rainforests; Sales; Tax revenues","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Aimed at enterprise-scale customers, these services range from the provision of IP-VPNs to full IT outsourcing, and span the range of infrastructure domains from desktop to data centre. The primary challenge lies not in the ICT infrastructure itself, but in the increasing demands placed upon the operational support systems (OSS) to deliver services holistically across the range of ICT operations. Based on BT's experience with corporate and government customers, this paper presents a detailed study of the ICT challenges on the OSS in achieving an end-to-end view of ICT service management. It proposes an architectural route forward and highlights BT's work on policy-based service management solutions.

Mass-market consumers can be divided between those who are informed about the existence of OSS and those who are uninformed. Since OSS producers have little incentive to advertise, there may be a substantial mass of uniformed consumers, leading to market failures that may justify government intervention. We study three government policies: (a) mandated adoption, whereby the government forces public agencies, schools, and universities to adopt OSS, (b) information provision, whereby the government informs the uninformed users about the existence and the characteristics of OSS, and (c) subsidy, whereby the government makes a payment to consumers if they adopt OSS. We show that mandated adoption and information provision may increase social welfare, but the subsidy always reduces it. When network externalities are added to the model, we show that mandated adoption and information provision may increase social welfare if they help the market to tip towards standardization.

It is an opportunity to diverge. We would therefore expect incompatible strains of software to develop, and consequently a demand for standardization to arise. However, this is only partly the case. In this paper we explore which other coordinative mechanisms are at work apart from committee standardization. We identify four other categories of coordinative mechanisms, and illustrate their relevance in OSS development. They complement committee standardization, can be used in standardization, and are sometimes an alternative to standardization.

Although resistance manifests itself in numerous ways, resistance to change is frequent when individuals are introduced to new ideas or innovations. This form of resistance can limit forward progress of either an individual or an organization. However, a few papers investigated possible positive roles of resistance in human life. This paper proposes that resistance can be a positive motivator to achieve change. Open source software (OSS) is a technological innovation that is laden with aspects of resistance. One of the initial motivations for the development of open source software was ""psychological reactance"" on the part of a few software developers. Reactance is a limited part of the overall construct of resistance; specifically, resistance caused by external threats to an individual's freedom of choice, which generally manifests itself affectively. This paper looks at the role of resistance as a motivator for technological innovation from the perspective of open source softwre development. It also presents techniques for overcoming resistance to the adoption of open source software. Specific techniques presented are the Alpha and Omega strategies for overcoming resistance. Alpha strategies work by attempting to increase the approach forces towards some goal. Conversely, Omega strategies attempt to decrease the avoidance forces, thereby removing resistance to change. Both techniques are used in the context of open source software development to motivate participants.","2004","2025-04-25 15:23:26","2025-04-25 15:23:26","","36","","","13","","","","","","","","","","English","","","ABI/INFORM Global","2500557958","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/0oCVI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Jqqm1SdxriyuNZlg3X%2Bd0e11DNg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Resistance+as+Motivation+for+Innovation%3A+Open+Source+Software&rft.au=Kavanagh%2C+Joseph+F.&rft.aulast=Kavanagh&rft.aufirst=Joseph&rft.date=2004-01-01&rft.volume=13&rft.issue=&rft.spage=36&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.01336","Open source software; Innovation; Motivation; Resistance; Open source; Open-source software; Computers--Information Science And Information Theory; Software development; Public domain; Innovations; Programmer; Reactance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The ""private investment"" model assumes returns to the innovator result from private goods and efficient regimes of intellectual property protection. The ""collective action"" model assumes that under conditions of market failure, innovators collaborate in order to produce a public good. The phenomenon of open source software development shows that users program to solve their own as well as shared technical problems, and freely reveal their innovations without appropriating private returns from selling the software. This paper proposes that open source software development is an exemplar of a compound ""private-collective"" model of innovation that contains elements of both the private investment and the collective action models and can offer society the ""best of both worlds"" under many conditions. A new set of research questions this model raises for scholars in organization science are described.","2003-04","2025-04-25 15:23:26","2025-04-25 15:23:26","","209-223","","2","14","","","","","","","","","","English","","","ABI/INFORM Global","213832398","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","; ","https://media.proquest.com/media/hms/OBJ/D51gT?_a=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%3D%3D&_s=0ARffPta%2Bf78rtxaNgkgiJ3O5ac%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Organization+Science&rft.atitle=Open+source+software+and+the+%26quot%3Bprivate-collective%26quot%3B+innovation+model%3A+Issues+for+organization+science&rft.au=Eric+von+Hippel%3BGeorg+von+Krogh.&rft.aulast=Eric+von+Hippel&rft.aufirst=&rft.date=2003-03-01&rft.volume=14&rft.issue=2&rft.spage=209&rft.isbn=&rft.btitle=&rft.title=Organization+Science&rft.issn=10477039&rft_id=info:doi/","Open source software; Innovation; Studies; Collective action; Business And Economics--Management; Collaboration; Artificial intelligence; Open-source software; Licenses; Incentives; Models; Software development; 5240:Software & systems; Public domain; Freeware; Innovations; Research & development--R&D; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; Defense contracts; Laboratories; Licensing; Organization science; Organization studies; Programmers; Research & development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Metadata is examined from the Linux Software Map (LSM), which documents many open source projects, and Sourceforge, one of the largest resources for open source developers.

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-25 15:23:27","2025-04-25 15:23:27","","94-112","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","821692253","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/8v97U?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU3NTkzNzIJODIxNjkyMjUzOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjE5OTkvMTAvMDFyCjE5OTkvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Qza5MQhKz7ImorWtd5i4IL1jV4k%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Open+source+software+and+software+patents%3A+A+constitutional+perspective&rft.au=Pfaffenberger%2C+Bryan.&rft.aulast=Pfaffenberger&rft.aufirst=Bryan&rft.date=1999-10-01&rft.volume=12&rft.issue=3&rft.spage=94&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-999-1029-x","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is difficult to further enrich the features of text encoding vectors. At the same time, most existing bug report classification methods ignore the submitter's personal information. To solve these problems, we construct nine personal information characteristics of bug report submitters in GitHub by survey. Then, we propose a GitHub bug report classification method named personal information fine‐tuning network (PIFTNet) based on transfer learning and the submitter's personal information. PIFTNet transfers the general text feature vectors in bidirectional encoder representation from transformers (BERT) to the domain of bug report classification by fine‐tuning the pre‐training parameters in BERT. It also combines the text characteristics and the characteristics of the submitter's personal information to construct the classification model. In addition, we propose a two‐stage training method to alleviate the catastrophic changes in the pre‐training parameters and loss of the initially learned knowledge caused by direct training of PIFTNet. We verify the proposed PIFTNet on the dataset extracted from GitHub and empirical results prove the effectiveness of PIFTNet.","2024-05","2025-04-25 15:24:13","2025-04-25 15:24:13","","","","5","41","","","","","","","","","","English","","","ABI/INFORM Global","3032788076","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Expert+Systems&rft.atitle=Classification+of+open+source+software+bug+report+based+on+transfer+learning&rft.au=Liao+Zhifang%3BWang%2C+Kun%3BZeng+Qi%3BLiu+Shengzong%3BZhang%2C+Yan%3BHe+Jianbiao.&rft.aulast=Liao+Zhifang&rft.aufirst=&rft.date=2024-05-01&rft.volume=41&rft.issue=5&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Expert+Systems&rft.issn=02664720&rft_id=info:doi/10.1111%2Fexsy.13184","Open source software; Computers--Artificial Intelligence; Personal information; Deep learning; Classification; Mathematical models; Debugging; Coding; Datasets; Bug report classification; Parameters; Submitter's personal information; Transfer learning; Tuning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, users often tend to acquire codes from the community and are reluctant to contribute their knowledge. Integrating the motivational theory and social capital theory, this article intends to explore users’ contribution in OSS communities. A mixed method of SEM and fsQCA was used to perform data analysis. We found that intrinsic motivations (flow experience and self-efficacy), extrinsic motivations (perceived reputation and reciprocity), social interaction ties, community identification, and common language positively affect users’ contribution intention. Trust has no effect on the contribution intention. The fsQCA results indicated that flow experience, perceived reputation, reciprocity and trust are the common core conditions of four configurations leading to contribution intention. The results suggest that OSS communities need to be concerned with users’ motivations and develop social capital in order to encourage their contribution.","2023-11","2025-04-25 15:24:13","2025-04-25 15:24:13","","1382-1393","","6","63","","","","","","","","","","English","","","ABI/INFORM Global","2884936915","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Examining+Users%26rsquo%3B+Contribution+in+Open+Source+Software+Communities&rft.au=Zhou%2C+Tao%3BYuan%2C+Qingqing.&rft.aulast=Zhou&rft.aufirst=Tao&rft.date=2023-11-01&rft.volume=63&rft.issue=6&rft.spage=1382&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2022.2155268","Open source software; Computers; contribution; Motivation; Social capital; Data analysis; Open source; Software; Open-source software; Reciprocity; fsQCA; Lingua franca; motivational theory; OSS community; Social factors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Two amendments are proposed. First, we add a new dimension to the framework, institutional competence (“where to own”), which denotes that individuals and firms have heterogeneous abilities to assess how an institutional environment affects the potential uses of a resource. Second, we argue that institutional uncertainty moderates the three original dimensions of the framework, impairing the exercise of ownership competence of some entrepreneurs and firms more than of others. We use examples from the literature to illustrate our arguments. We also discuss the implications of our analysis.Managerial SummaryThe ownership competence framework is built on the idea that business owners have different abilities to deploy resources and create value. Starting from this contribution, we shed light on the specific role that the institutional environment plays in the exercise of ownership competence. We argue that the ownership competence framework must explicitly consider where ownership takes place in order to explain the actions of entrepreneurs and firms. We also claim that institutional uncertainty can influence value creation in more subtle ways than indicated in the original formulation of the ownership competence framework. All in all, this article paves the way for institutional aspects to be considered more explicitly in the strategic analysis of ownership.","2023-08","2025-04-25 15:24:13","2025-04-25 15:24:13","","1939-1954","","8","44","","","","","","","","","","English","","","ABI/INFORM Global","2834858422","","","Place: Chicago Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Strategic+Management+Journal&rft.atitle=Disentangling+the+role+of+the+institutional+environment+in+the+ownership+competence+framework%3A+A+comment+on+Foss+et+al.+%282021%29&rft.au=Monteiro%2C+Guilherme+Fowler+A%3BBruno+Varella+Miranda.&rft.aulast=Monteiro&rft.aufirst=Guilherme+Fowler&rft.date=2023-08-01&rft.volume=44&rft.issue=8&rft.spage=1939&rft.isbn=&rft.btitle=&rft.title=Strategic+Management+Journal&rft.issn=01432095&rft_id=info:doi/10.1002%2Fsmj.3462","Institution; Uncertainty; Business And Economics--Management; Ownership; Companies; value creation; Strategic management; Business ownership; Competence; Entrepreneurs; Frame analysis; Institutional aspects; institutional competence; institutional environment; institutional uncertainty; Owners; ownership competence; Value creation; Value proposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The flaw led to risks in software used by government agencies, Web service providers such as Amazon Web Services and Apple iCloud, and even video games such as Minecraft. The Log4J issue earned a rare rating of 10 on the Common Vulnerability Scoring System, signaling the highest level of risk, and cybersecurity experts warned the effects could be felt for years until every affected program can be secured.

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-25 15:24:13","2025-04-25 15:24:13","","361","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","2783221355","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Resilience+in+the+Open+Source+Software+Community%3A+How+Pandemic+and+Unemployment+Shocks+Influence+Contributions+to+Others%27+and+One%27s+Own+Projects&rft.au=Malgonde%2C+Onkar+S%3BSaldanha%2C+Terence+J+V%3BMithas%2C+Sunil.&rft.aulast=Malgonde&rft.aufirst=Onkar&rft.date=2023-03-01&rft.volume=47&rft.issue=1&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2022%2F17256","Open source software; COVID-19; Computers; Resilience; Pandemics; Public health; Community; Open source; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Nature conservation; Resource conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023","2025-04-25 15:24:14","2025-04-25 15:24:14","","3106-3130","","5","49","","","","","","","","","","English","","","ABI/INFORM Global","2814541650","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Understanding+Mentors%26rsquo%3B+Engagement+in+OSS+Communities+via+Google+Summer+of+Code&rft.au=Tan%2C+Xin%3BZhou%2C+Minghui%3BZhang%2C+Li.&rft.aulast=Tan&rft.aufirst=Xin&rft.date=2023-01-01&rft.volume=49&rft.issue=5&rft.spage=3106&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2023.3242415","Open source software; Organizations; Mentors; Motivation; Data analysis; Students; Open-source software; Task analysis; Strategy; Mentoring; Sustainability; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; Computers--Software; taxonomy; Challenge; mentoring process; Mentorship; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader.

Building on existing OSS research, we explore norms with respect to collaboration, i.e., how developers assign, discuss, and complete tasks, in an orgsOSS project.

Widely shared reports indicate that gender differences may be specific to each region. However, how complete can these reports be with little to no research reflective of the Open Source Software (OSS) process and communities software is now commonly developed in? Our study presents a multi-region geographical analysis of gender inclusion on GitHub. This mixed-methods approach includes quantitatively investigating differences in gender inclusion in projects across geographic regions and investigate these trends over time using data from contributions to 21,456 project repositories. We also qualitatively understand the unique experiences of developers contributing to these projects through a survey that is strategically targeted to developers in various regions worldwide. Our findings indicate that gender diversity is low across all parts of the world, with no substantial difference across regions. However, there has been statistically significant improvement in diversity worldwide since 2014, with certain regions such as Africa improving at faster pace. We also find that most motivations and barriers to contributions (e.g., lack of resources to contribute and poor working environment) were shared across regions, however, some insightful differences, such as how to make projects more inclusive, did arise. From these findings, we derive and present implications for tools that can foster inclusion in open source software communities and empower contributions from everyone, everywhere.","2022","2025-04-25 15:24:14","2025-04-25 15:24:14","","3394-3409","","9","48","","","","","","","","","","English","","","ABI/INFORM Global","2714955135","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Including+Everyone%2C+Everywhere%3A+Understanding+Opportunities+and+Challenges+of+Geographic+Gender-Inclusion+in+OSS&rft.au=Gede+Artha+Azriadi+Prana%3BFord%2C+Denae%3BRastogi%2C+Ayushi%3BLo%2C+David%3BPurandare%2C+Rahul%3BNagappan%2C+Nachiappan.&rft.aulast=Gede+Artha+Azriadi+Prana&rft.aufirst=&rft.date=2022-01-01&rft.volume=48&rft.issue=9&rft.spage=3394&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2021.3092813","Open source software; GitHub; gender; software engineering; Software engineering; OSS; Software; Open-source software; diversity; Industries; empirical studies; Gender issues; Software development management; Europe; Public domain; Computers--Software; Industrial development; Gender; Gender aspects; Gender diversity; Gender gap; geographic regions; Geographical distribution; Inclusion; Toy manufacturing industry; Working conditions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While this model lowers the barrier to entry for OSS developers by synthesizing, automating and optimizing the contribution process, coordination among an increasing number of contributors remains as a challenge due to the asynchronous and self-organized nature of distributed development. In particular, duplicate contributions, where multiple different contributors unintentionally submit duplicate pull requests to achieve the same goal, are an elusive problem that may waste effort in automated testing, code review and software maintenance. While the issue of duplicate pull requests has been highlighted, to what extent duplicate pull requests affect the development in OSS communities has not been well investigated. In this paper, we conduct a mixed-approach study to bridge this gap. Based on a comprehensive dataset constructed from 26 popular GitHub projects, we obtain the following findings: (a) Duplicate pull requests result in redundant human and computing resources, exerting a significant impact on the contribution and evaluation process. (b) Contributors’ inappropriate working patterns and the drawbacks of their collaborating environment might result in duplicate pull requests. (c) Compared to non-duplicate pull requests, duplicate pull requests have significantly different features, e.g., being submitted by inexperienced contributors, being fixing bugs, touching cold files, and solving tracked issues. (d) Integrators choosing between duplicate pull requests prefer to accept those with early submission time, accurate and high-quality implementation, broad coverage, test code, high maturity, deep discussion, and active response. Finally, actionable suggestions and implications are proposed for OSS practitioners.","2022","2025-04-25 15:24:14","2025-04-25 15:24:14","","1309-1335","","4","48","","","","","","","","","","English","","","ABI/INFORM Global","2650298132","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Redundancy%2C+Context%2C+and+Preference%3A+An+Empirical+Study+of+Duplicate+Pull+Requests+in+OSS+Projects&rft.au=Li%2C+Zhixing%3BYu%2C+Yue%3BZhou%2C+Minghui%3BWang%2C+Tao%3BYin%2C+Gang%3BLong%2C+Lan%3BWang%2C+Huaimin.&rft.aulast=Li&rft.aufirst=Zhixing&rft.date=2022-01-01&rft.volume=48&rft.issue=4&rft.spage=1309&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2020.3018726","Automation; Collaboration; Tools; Context; Testing; Encoding; Computer bugs; Synchronization; social coding; Project; Computers--Software; Integrators; Cloning; distributed collaboration; Duplicate pull requests; pull-based development model; Redundancy; Reproduction (copying)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some questions are raised, such as: (1) To what extent do organizations linked with Collaborative Economy make use of Free and Open Source Software?, (2) What are the incentives that motivate the implementation of Free and Open Source Software in Collaborative Economy companies?, (3) What use do Collaborative Economy companies give to Free and Open Source Software?, and (4) Is there a greater use of Free and Open Source Software expected for the coming years among these organizations? To answer these questions, a study based on the Delphi method has been designed. To this end, a panel of 15 high-level experts in the field was formed.

For instance, open source software (OSS) is developed by mass collaboration on digital communities to provide software users free alternatives to commercial products. OSS is particularly valuable to meet the needs of numerous disadvantaged users for whom proprietary software is not affordable. While OSS projects are lack of formal organizational structure, project leaders play a significant role in initiating and managing these projects and eventually, influencing the degree to which the developed software is used and liked by users. Drawing on resource dependence theory, we investigate the impacts of two team‐level characteristics of OSS project leaders (ie, size and tenure) on how well the developed software can address users' needs, with regard to the quantity of software being used by users and the quality of software to users' satisfaction. Further, from a resource dependence perspective, we examine the moderating role of project leaders' network ties in shaping the contingency of these effects. By using a large‐scale dataset from 43 048 OSS development projects in SourceForge community, we find empirical evidence corroborating our theory. Taken together, our findings suggest the boundary‐spanning role of project leaders in developing digital social innovation.","2021-09","2025-04-25 15:24:14","2025-04-25 15:24:14","","672-694","","5","31","","","","","","","","","","English","","","ABI/INFORM Global","2559383916","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=Project+leaders+as+boundary+spanners+in+open+source+software+development%3A+A+resource+dependence+perspective&rft.au=John+Qi+Dong%3BG%C3%B6tz%2C+Sebastian+Johannes.&rft.aulast=John+Qi+Dong&rft.aufirst=&rft.date=2021-09-01&rft.volume=31&rft.issue=5&rft.spage=672&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12313","Open source software; Open source; software development; open source software; Open-source software; resource dependence theory; social innovation; Computers--Computer Systems; Software development; Public domain; Freeware; Project; Innovations; Organizational structure; User satisfaction; Contingency; digital innovation; project leaders; Resource dependence theory; Social innovation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-player game and examine how open-source licensing affects competition among an open-source originator, an open-source contributor, and a proprietor competing in an enterprise software market. In this regard, we examine (1) how quality investments and prices are endogenously determined in equilibrium, (2) how license restrictiveness impacts equilibrium investments and the quality of offerings, and (3) how license restrictiveness affects consumer surplus and social welfare. Although some in the open-source community often advocate restrictive licenses such as the GNU General Public License because it is not always in the best interest of the originator for the contributor to invest greater development effort, such licensing can actually be detrimental to both consumer surplus and social welfare when it exacerbates this incentive conflict. We find such an outcome in markets characterized by software providers with similar development capabilities yet cast in favor of the proprietor. In contrast, when these capabilities either become more dispersed or remain similar but tilt in favor of open source, a more restrictive license instead encourages greater effort from the OSS contributor, leads to higher OSS quality, and provides a larger societal benefit.","2021-05","2025-04-25 15:24:14","2025-04-25 15:24:14","","3041","","5","67","","","","","","","","","","English","","","ABI/INFORM Global","2536540439","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+Science&rft.atitle=Competition+Among+Proprietary+and+Open-Source+Software+Firms%3A+The+Role+of+Licensing+in+Strategic+Contribution&rft.au=August%2C+Terrence%3BChen%2C+Wei%3BZhu%2C+Kevin.&rft.aulast=August&rft.aufirst=Terrence&rft.date=2021-05-01&rft.volume=67&rft.issue=5&rft.spage=3041&rft.isbn=&rft.btitle=&rft.title=Management+Science&rft.issn=00251909&rft_id=info:doi/10.1287%2Fmnsc.2020.3674","Open source software; Software; Open-source software; Licenses; Incentives; Companies; Competition; Game theory; Markets; Public domain; Licensing; Business And Economics--Labor And Industrial Relations; Prices; Best interests; Economic value added; Equilibrium; Social welfare","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

What is the nature of these novel arrangements? Does volunteers’ participation remain critical for these ecosystems? Despite extensive research on commercial participation in OSS, the exact nature and extent of company contributions to OSS development, and the impact of this engagement may have on the volunteer community have not been clarified. To bridge the gap, we perform an exploratory study of OpenStack: a large OSS ecosystem with intense commercial participation. We quantify companies’ contributions via the developers that they provide and the commits made by those developers. We find that companies made far more contributions than volunteers and the distribution of the contributions made by different companies is also highly unbalanced. We observe eight unique contribution models based on companies’ commercial objectives and characterize each model according to three dimensions: contribution intensity, extent, and focus. Companies providing full cloud solutions tend to make both intensive (more than other companies) and extensive (involving a wider variety of projects) contributions. Usage-oriented companies make extensive but less intense contributions. Companies driven by particular business needs focus their contributions on the specific projects addressing these needs. Minor contributors include community players (e.g., the Linux Foundation) and research groups. A model relating the number of volunteers to the diversity of contribution shows a strong positive association between them.","2021","2025-04-25 15:24:14","2025-04-25 15:24:14","","2242-2259","","10","47","","","","","","","","","","English","","","ABI/INFORM Global","2582248219","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Companies%26rsquo%3B+Participation+in+OSS+Development%26ndash%3BAn+Empirical+Study+of+OpenStack&rft.au=Zhang%2C+Yuxia%3BZhou%2C+Minghui%3BMockus%2C+Audris%3BJin%2C+Zhi.&rft.aulast=Zhang&rft.aufirst=Yuxia&rft.date=2021-01-01&rft.volume=47&rft.issue=10&rft.spage=2242&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2019.2946156","Open source software; Cloud computing; software development; Software engineering; Software; Open-source software; Linux; Ecosystems; Companies; Biological system modeling; Computers--Software; Open source ecosystem; Company; commercial participation; contribution extent; contribution focus; contribution intensity; Openstack","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research investigates the variety of work practices used in public communication channels by company contributors to engage with and contribute to eight community OSS projects. Through interviews with contributors to the eight projects we draw on their experiences and insights to explore the motivations to use particular methods of contribution. We find that companies utilise work practices for contributing to community projects which are congruent with the circumstances and their capabilities that support their short- and long-term needs. We also find that companies contribute to community OSS projects in ways that may not always be apparent from public sources, such as employing core project developers, making donations, and joining project steering committees in order to advance strategic interests. The factors influencing contributor work practices can be complex and are often dynamic arising from considerations such as company and project structure, as well as technical concerns and commercial strategies.

Despite its ubiquity, there is a lack of empirical evidence to validate the relative position of each task cluster within the onion model. In this study, we map out the community structure of a large open source project and observe its bug‐fixing patterns to explore the relationship between tasks and structure. Our study makes three significant contributions. First, we find no empirical evidence to support the structural location of bug‐fixing tasks in the onion structure. Second, we find empirical evidence to support the core‐periphery continuum model linking an actor’s coreness to problem‐solving ability. Third, our results suggest that the importance and location of each task within the core‐periphery structure evolve over time.

While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 15:24:15","2025-04-25 15:24:15","","369-402","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2352536913","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+Third+Design+Space%3A+A+postcolonial+perspective+on+corporate+engagement+with+open+source+software+communities&rft.au=Kendall%2C+Kenneth+E%3BKendall%2C+Julie+E%3BGermonprez%2C+Matt%3BMathiassen%2C+Lars.&rft.aulast=Kendall&rft.aufirst=Kenneth&rft.date=2020-03-01&rft.volume=30&rft.issue=2&rft.spage=369&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12270","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Computers--Computer Systems; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 15:24:15","2025-04-25 15:24:15","","764","","3","30","","","","","","","","","","English","","","ABI/INFORM Global","2307721543","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Does+Superposition+Influence+the+Success+of+FLOSS+Projects%3F+An+Examination+of+Open-Source+Software+Development+by+Organizations+and+Individuals&rft.au=Medappa%2C+Poonacha+K%3BSrivastava%2C+Shirish+C.&rft.aulast=Medappa&rft.aufirst=Poonacha&rft.date=2019-09-01&rft.volume=30&rft.issue=3&rft.spage=764&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2018.0829","Open source software; Organizations; Motivation; Open source; Software engineering; Open-source software; Computer architecture; Ownership; Success; Computers--Information Science And Information Theory; Project management; Software development; Freeware; 51821:Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services; Modular design; Project Success; Superposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person–environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity. We discuss the implications of our findings for research and practice.","2019-09","2025-04-25 15:24:15","2025-04-25 15:24:15","","951","","3","43","","","","","","","","","","English","","","ABI/INFORM Global","2283390283","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Developer+Centrality+and+the+Impact+of+Value+Congruence+and+Incongruence+on+Commitment+and+Code+Contribution+Activity+in+Open+Source+Software+Communities&rft.au=Maruping%2C+Likoebe+M%3BDaniels%2C+Sherae+L%3BCataldo%2C+Marcelo.&rft.aulast=Maruping&rft.aufirst=Likoebe&rft.date=2019-09-01&rft.volume=43&rft.issue=3&rft.spage=951&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2019%2F13928","Open source software; Uncertainty; Computers; Collaboration; Open source; Software; Open-source software; Regression analysis; Social networks; Commitment; Public domain; Developer; Impact fees; Congruence; Polynomials","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors draw on a case study of the ‘Heidi bug’ discovered during the development of the Mozilla Firefox web browser to examine how ‘gendered talk’ was (en)‐acted to facilitate ‘bricolage’ in an online work environment. Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender‐balanced, women‐friendly and inclusive workplace certainly would benefit from a more diverse environment. This article highlights the gendered aspect of software development through examining the language use and mainstream ‘bricolage’ practice, and establishes a compelling ground for enlarging the talent pool to include more women and integrating gender ethics (e.g., raising awareness of sensitive language and design approaches) into computer ethics education.","2019-07","2025-04-25 15:24:15","2025-04-25 15:24:15","","1017-1031","","7","26","","","","","","","","","","English","","","ABI/INFORM Global","2257969279","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Gender%2C+Work+and+Organization&rft.atitle=Gendered+work+culture+in+free%2Flibre+open+source+software+development&rft.au=Yu%E2%80%90Wei+Lin%3Bden+Besten%2C+Matthijs.&rft.aulast=Yu%E2%80%90Wei+Lin&rft.aufirst=&rft.date=2019-07-01&rft.volume=26&rft.issue=7&rft.spage=1017&rft.isbn=&rft.btitle=&rft.title=Gender%2C+Work+and+Organization&rft.issn=09686673&rft_id=info:doi/10.1111%2Fgwao.12255","Open source software; Ethics; Qualitative research; Masculinity; Women; Business And Economics--Management; open innovation; Software; Feminism; Case studies; Internet; Software development; Case study; Public domain; Freeware; Property; Corporate culture; Free; Work environment; Consciousness; Computer ethics; Gender; Ability; Bricolage; Cultural change; free/libre open source software; gendered talks; Hegemony; heterohegemonic masculinity; Heterosexuality; humour; Ignorance; Language usage; Moral education; online virtual work space; Organizational culture; work cultures; Workplaces","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The studied branch focuses on developing Android phones. This paper presents contribution strategies and triggers for openness. These strategies include avoid forking OSS tools, empower developers to participate in the ecosystem, steer ecosystems through contributions, create business through differentiation, and create new ecosystems.

Knowledge can be shared among individuals, groups, and organizations. A free software community is a type of community of practice arranged around a specific free software, where the knowledge shared is complex and the knowledge sharing processes have scarcely been studied. This investigation aims to identify the profiles of knowledge sharing processes in free software communities and examine how 6 motivations for sharing knowledge in free software communities are associated with each of the clusters. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters were identified: Sporadic Sharer; Collector; Donator; and Constant Sharer. With the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators and Collectors. These results confirm the view of free software communities as communities of practice and highlight the importance of knowledge sharing in free software development cycle. The results reveal the importance of the Constant Sharer profile, which has the highest rates of donation and collection and is also the profile in which all the motivations appear with the highest values, indicating its key role in the functioning of free software communities.","2018-09","2025-04-25 15:24:15","2025-04-25 15:24:15","","143-152","","3","25","","","","","","","","","","English","","","ABI/INFORM Global","2082030930","","","Place: Chichester Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge+and+Process+Management&rft.atitle=The+life+cycle+process+of+knowledge+sharing+in+free+software+communities%3A+Sharing+profiles+and+motivations&rft.au=Balle%2C+Andrea+Raymundo%3BOliveira%2C+M%C3%ADrian.&rft.aulast=Balle&rft.aufirst=Andrea&rft.date=2018-07-01&rft.volume=25&rft.issue=3&rft.spage=143&rft.isbn=&rft.btitle=&rft.title=Knowledge+and+Process+Management&rft.issn=10924604&rft_id=info:doi/10.1002%2Fkpm.1569","Motivation; Business And Economics--Management; Software; Knowledge sharing; Free software; Software development; Freeware; Life cycle engineering; Communities of practice; Cluster analysis; Community of practice; Intellectual capital","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some others have investigated knowledge management among open-source-software (OSS) developers and discussed factors influencing knowledge transfer within development teams (e.g. Joshi and Sarker, 2006). In the domain of open source software (OSS) communities, more companies are now attempting to establish relationships to benefit from these potential value-creating communities; and project managers could in fact target different goals within software development teams including knowledge transfer within and between teams. We step forward to distinguish knowledge transfer within groups as opposed to knowledge transfer between groups; where relevant projects are bundled into separate strongly intra-connected groups. In knowledge management literature there is a trade-off between sparse network structures (Burt, 2000, 2002) versus dense network structures (Walker et al., 1997; Coleman, 1988). It is argued that the former facilitates the diffusion and generation of ideas among groups, while the latter affects the implementation of idea within each dense group. To our best knowledge, there has been no study to investigate the relationship between dense and sparse network structures. We propose that knowledge transfer within dense groups has a positive influence on knowledge transfer between sparse groups, in that intragroup density, group size, developers centrality and betweenness could impact intergroup coupling. To prove our hypothesis, we use a complex network of open source software (OSS) as the domain of interest, where developers represent nodes and two developers contributing to a project task represent a network tie. Developers contributing to tasks in groups other than their own can explore novel ideas via sharing knowledge, whereas developers contributing to tasks inside groups exploit ideas to improve those projects. We investigate the idea both analytically and empirically within 4 months, 8 months and 1 year lagged time, and finally show that intragroup density has a positive whereas developers’ centrality has a negative influence on intergroup coupling.","2018-02","2025-04-25 15:24:15","2025-04-25 15:24:15","","167","","1","38","","","","","","","","","","English","","","ABI/INFORM Global","2048526571","","","Place: Kidlington Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Management&rft.atitle=Knowledge+management+in+OSS+communities%3A+Relationship+between+dense+and+sparse+network+structures%3A+SSIS&rft.au=Behfar%2C+Stefan+Kambiz%3BTurkina%2C+Ekaterina%3BBurger-Helmchen%2C+Thierry.&rft.aulast=Behfar&rft.aufirst=Stefan&rft.date=2018-02-01&rft.volume=38&rft.issue=1&rft.spage=167&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Management&rft.issn=02684012&rft_id=info:doi/","Open source software; Community; Knowledge transfer; Open-source software; Knowledge management; Knowledge sharing; Information sharing; Centrality; Software development; Coupling; Public domain; 23721:Land Subdivision; Developers; Social Sciences: Comprehensive Works; Betweenness; Source code; Sparse network","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS.

Une investigation des projets moins connus permettrait une compréhension plus complete et d'éviter un taux d'échec important des projets OSS. Cette étude investigue donc la combi- naison de trois facteurs : les interactions des utilisateurs et développeurs, la pénétration du marché et le stade de développement, afin d'observer leur impact sur la popularité des projets OSSpeu connus. Nous a vons pour cela développé un modele empirique de la popularité des OSS, et avons testé nos hypotheses sur 657projets de logiciel libre.

The study proposes a theoretical framework, under the prism of which socio-economic, technological and institutional factors critical to eGovernment and OSS are revealed. The hypotheses are evaluated by means of an econometric model of simultaneous equations. In order to better gauge the results of the hypotheses, the model is evaluated over economic environments at different stages of development. Social development and OSS growth were found to be the most important facilitators for eGovernment maturity, across countries of all stages of development. Institutional quality, technological openness, freedom in press and the macro-economic environment exerted different weights of importance across different country groupings. Findings also suggest that technological infrastructure and innovation are important drivers for OSS growth across countries at all stages of development.

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 15:24:16","2025-04-25 15:24:16","","116","","1","32","","","","","","","","","","English","","","ABI/INFORM Global","1697517813","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+Information+Systems&rft.atitle=Exploitation+and+Exploration+Networks+in+Open+Source+Software+Development%3A+An+Artifact-Level+Analysis%3A+JMIS&rft.au=Temizkan%2C+Orcun%3BKumar%2C+Ram+L.&rft.aulast=Temizkan&rft.aufirst=Orcun&rft.date=2015-07-01&rft.volume=32&rft.issue=1&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+Information+Systems&rft.issn=07421222&rft_id=info:doi/","Open source software; Political Science; Studies; Open source; Software engineering; Software; Open-source software; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual developers contribute to developing the software, but do not hold the copyright to appropriate its value. This raises questions regarding motives behind such effort. We provide an integrated model of developers' incentives to describe OSS development and compare restrictive OSS licenses that force all modifications to be kept open with non-restrictive OSS licenses that allow proprietary ownership of modified works. Different incentives govern effort provision at different stages of the software development process. We show that open-source licenses can provide socially valuable software when a proprietary license fails to do so. We also show that restrictive OSS licenses generate greater effort provision in the design stage of software development relative to non-restrictive licenses. Endogenizing licensing choice, we find that a project leader chooses a non-restrictive OSS license if reputational concerns drive developers' incentives, a proprietary license when there is a large population of users in the market and a restrictive OSS license if user population is small but reputational benefit is high. Our results resonate well with empirical findings and suggest additional testable implications about the relationship between licensing and software project characteristics. Finally, we also find that the market under-provides restrictive OSS licenses relative to the efficient level, suggesting the need for subsidizing restrictive licenses in some cases.","2015-07","2025-04-25 15:24:17","2025-04-25 15:24:17","","1381","","3","15","","","","","","","","","","English","","","ABI/INFORM Global","1693624750","","","Place: Berkeley Publisher: Berkeley Electronic Press","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+B.E.+Journal+of+Economic+Analysis+%26+Policy&rft.atitle=Developers%27+Incentives+and+Open-Source+Software+Licensing%3A+GPL+vs+BSD&rft.au=Atal%2C+Vidya%3BShankar%2C+Kameshwari.&rft.aulast=Atal&rft.aufirst=Vidya&rft.date=2015-07-01&rft.volume=15&rft.issue=3&rft.spage=1381&rft.isbn=&rft.btitle=&rft.title=The+B.E.+Journal+of+Economic+Analysis+%26+Policy&rft.issn=21946108&rft_id=info:doi/","Open source software; Studies; Open source; Software engineering; Software license; Open-source software; Licenses; License; Software development; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; Developer; Proprietary; Licensing; 1130:Economic theory; Public good; Business And Economics--Economic Systems And Theories, Economic History; Economic models; Incentive","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This increasing attention is a result of the remarkable growth in the number of OSS applications in recent years. Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1,409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest. These findings have implications for both the OSS research community and OSS practitioners.","2015","2025-04-25 15:24:17","2025-04-25 15:24:17","","28","","1","25","","","","","","","","","","English","","","ABI/INFORM Global","1654703565","","","Place: Mahwah Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.atitle=Investigating+the+Interrelationships+among+Success+Measures+of+Open+Source+Software+Projects&rft.au=Ghapanchi%2C+Amir+Hossein.&rft.aulast=Ghapanchi&rft.aufirst=Amir&rft.date=2015-01-01&rft.volume=25&rft.issue=1&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.issn=10919392&rft_id=info:doi/","Open source software; Studies; Open source; Software; Open-source software; Success; Sustainability; Project management; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Software Projects; Project Success; Business And Economics--Computer Applications; Management theory; Release management; Sustainability management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. They also reproduced the results on new data provided by Mozilla. The authors constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants.

Currently, there exists no working operationalization available that can be used to determine the health of open source ecosystems. Health is typically looked at from a project scope, not from an ecosystem scope. With such an operationalization, stakeholders can make better decisions on whether to invest in an ecosystem: developers can select the healthiest ecosystem to join, keystone organizers can establish which governance techniques are effective, and end-users can select ecosystems that are robust, will live long, and prosper. Design research is used to create the health operationalization. The evaluation step is done using four ecosystem health projects from literature. The Open Source Ecosystem Health Operationalization is provided, which establishes the health of a complete software ecosystem, using the data from collections of open source projects that belong to the ecosystem. The groundwork is done, by providing a summary of research challenges, for more research in ecosystem health. With the operationalization in hand, researchers no longer need to start from scratch when researching open source ecosystems' health.","2014-11","2025-04-25 15:24:17","2025-04-25 15:24:17","","1508","","11","56","","","","","","","","","","English","","","ABI/INFORM Global","1552455145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Measuring+the+health+of+open+source+software+ecosystems%3A+Beyond+the+scope+of+project+health&rft.au=Jansen%2C+Slinger.&rft.aulast=Jansen&rft.aufirst=Slinger&rft.date=2014-11-01&rft.volume=56&rft.issue=11&rft.spage=1508&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Decision making; Studies; Open source; Software engineering; Software; Software ecosystem; 9130:Experiment/theoretical treatment; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Project; Computers--Data Base Management; Design research; Ecosystem health; End users; Operationalization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We propose a methodology -- based on situated analyses of a formal design process used in the Python project -- to identify the distribution of actual roles (implementation, interactive, group, and design oriented) performed by participants into and between the spaces (defining boundary spaces). This notion of roles is grounded in collaborative design activities performed online by participants. This way, our findings complete the core-periphery model of participation in OSS. Concerning the distribution of roles between spaces, we reveal a map of participation in OSS: The majority of participants are pure discussants, but all participants in the implementation spaces do also act in the discussion space, and few participants act at boundary spaces. Concerning the distribution of roles between participants in the discussion space, we reveal that interactions are structured by a central hub (occupied by key participants) and that, whereas design-oriented roles are spread among all participants, group-oriented roles are performed by one or two participants in the respective spaces and at their boundary. Finally, combination of roles reveals five individual profiles performed by participants. Our approach could be extended to other design situations to explore relationships between forms of participation -- in particular, those revealing use-oriented contributions -- performance, and quality of the design product. Finally, it could be a basis for specifying tools to monitor and manage community activity for both research issues and support of online community.

Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (0395 and 0400), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that -- (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described.

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving.

While prior research has explored the communal nature of open source software development among individual users, little research has explored whether these sharing concepts are also present in organizational use of open source software products. This study uses a theory integration approach to develop some initial insight into the differences between users and non-users of open source software. This study observed three groups of factors from six case studies of information sharing in the context of organizational open source software use. These factors were integrated with prior research in order to understand the physical and managerial barriers to, and enablers of, open source. The study proposes that open source users have more extensive knowledge sharing and teamwork practices in place, and are more tolerant of risk. The study also argues that open source users depended less on external technology support services but have more extensive information technology (IT) support structures.

Three configurations were identified: Defined Community, Open Community, and Authoritarian Community. Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team. The results provide guidance for practitioners about how to combine 19 identified governance mechanisms into effective project governance that stimulates productive participation.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.

Using detailed data collected from code repositories from SoureForge.com, we find that developer team structure and software architecture significantly moderate each other's effect on OSS development performance. Larger teams tend to produce more favorable project performance when the project being developed has a high level of structural interdependency while projects with a low level of structural interdependency require smaller teams in order to achieve better project performance. Meanwhile, centralized teams tend to have a positive impact on project performance when the OSS project has a high level of structural interdependency. However, when a project has a low level of structural interdependency, centralized teams can impair project performance. This study extends our understanding of information technology's deep engagement in organizational life and provides directions for open source practitioners to better organize their projects to achieve greater performance.

Recent examples appear to lend support to this, but there exist many detractors of OSS and resistance to the transformation it creates. Thus, it is relevant to take a closer look at the institutionalization of OSS. This paper evaluates the extent of OSS institutionalization in organizations. A practice or innovation is said to be institutionalized when it is taken-for-granted and its use becomes the norm. Drawing on institutional theory, the underlying concept of organizing vision and the rhetorical theory of diffusion of innovations, the authors analyze OSS institutionalization through the observation of the evolution of the public discourse about OSS and, simultaneously, the observation of the rate of adoption or diffusion of OSS in organizations.","2012-12","2025-04-25 15:24:18","2025-04-25 15:24:18","","1308","","12","54","","","","","","","","","","English","","","ABI/INFORM Global","1037945028","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Has+open+source+software+been+institutionalized+in+organizations+or+not%3F&rft.au=Marsan%2C+Josianne%3BPar%C3%A9%2C+Guy%3BWybo%2C+Michael+D.&rft.aulast=Marsan&rft.aufirst=Josianne&rft.date=2012-12-01&rft.volume=54&rft.issue=12&rft.spage=1308&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Institutionalization; Studies; Open source; Software engineering; Open-source software; Organizing vision; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Technological change; Organization theory; Computers--Data Base Management; Diffusion of innovations; Institutionalisation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, few studies have focused on the start-ups that enter the market just to exploit the new business opportunities stemming from the freely available technological knowledge developed by the FLOSS community (FLOSS-based start-ups). This paper aims to fill this gap by providing descriptive evidence about these firms. We address two main research questions: 1) What are the main features of FLOSS-based start-ups?; 2) What is their innovation process? We show that FLOSS-based start-ups follow a typical open innovation model that enables them to serve market niches that large incumbents are not structurally able to cover, profiting from the local production, distribution, and use of technological knowledge.

Developing these resources can be expensive and time consuming. Even when data and tools are intended for public re-use they often come with technical, legal, economic and social barriers that make them difficult to adopt, adapt and combine for use in new contexts. We focus on the promise of open, publically accessible software and data as well as crowdsourcing techniques to develop robust energy analysis tools that can deliver crucial, policy-relevant insight, particularly in developing countries, where planning resources are highly constrained -- and the need to adapt these resources and methods to the local context is high. We survey existing research, which argues that these techniques can produce high-quality results, and also explore the potential role that linked, open data can play in both supporting the modelling process and in enhancing public engagement with energy issues.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

In empirical organizational research, the analysis of two-mode networks is typically accomplished either by (a) decomposition of the dual structure into its two unimodal components defined in terms of indirect relations between entities of the same kind or (b) direct statistical analysis of individual two-mode dyads. Both strategies are useful, but neither is fully satisfactory. In this article, the authors introduce newly developed stochastic actor-based models for two-mode networks that may be adopted to redress the limitations of current analytical strategies. The authors specify and estimate the model in the context of data they have collected on the dual association between software developers and software problems observed during a complete release cycle of an open source software project. The authors discuss the general methodological implications of the models for organizational research based on the empirical analysis of two-mode networks.

In this paper, I use evidence from the United States and Canada to examine the distribution of these benefits and costs. I argue that although the rhetoric surrounding OSS is supported empirically, the benefits of OSS have been limited because of the way this technological project has evolved within its associated policy environment. That is, although ostensibly neutral, the policies and laws of both the U.S. and Canadian governments have tended to be positioned implicitly against the use of OSS both in the public sector and in the economy generally. In addition, OSS use and development requires a set of skills that are absent in many instances or create prohibitively high costs. Thus OSS is typically used by larger organizations, and its development is restricted to a mostly male, highly educated, high-income group of contributors. Therefore while the benefits of OSS are real, the distribution of these benefits is skewed.

To benefit from this opportunity, it is important to understand the strategic factors and future trends that affect the development of an efficient FLOSS economy in developing countries. This paper aims to examine the strategic factors and future trends that are likely to affect the development and deployment of FLOSS in Turkey. Based on the internal and external factors identified through the practice of technological foresight, a SWOT analysis will be carried out to identify the strengths, weaknesses, opportunities and threats for Turkey in creating a competitive software industry that can benefit from the advantages of FLOSS. Accordingly, with regard to the required technical infrastructure, an innovative/competitive business climate, skilled human resources and support for institutional structures, policy suggestions are outlined here that could be usefully implemented by government, industry and universities.

The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Following an initial systematic literature review to generate seed category data constructs, the authors performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source.

This in turn is influenced by three types of social capital - relational capital, cognitive capital and structural capital. In addition, this study also examines two moderating effects - the impact of technical complexity on the relationship between cognitive capital and expertise integration, and of task interdependence on the relationship between expertise integration and task completion. Through a field survey of 160 OSS members from five Taiwanese communities, there is support for some of the proposed hypotheses. Both reciprocity and centrality affect expertise integration as expected, but the influence of commitment and cognitive capital (including expertise and tenure) on expertise integration is not significant. Finally, expertise integration affects both team size and team effort, which in turn jointly influence task completion. This research contributes to advancing theoretical understanding of the effectiveness of free OSS development as well as providing OSS practitioners with insight into how to leverage social capital for improving the performance of OSS development.","2011-03","2025-04-25 15:24:19","2025-04-25 15:24:19","","195-219","","2","21","","","","","","","","","","English","","","ABI/INFORM Global","848569202","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+factors+that+affect+the+performance+of+open+source+software+development+-+the+perspective+of+social+capital+and+expertise+integration&rft.au=Chou%2C+Shih-Wei%3BHe%2C+Mong-Young.&rft.aulast=Chou&rft.aufirst=Shih-Wei&rft.date=2011-03-01&rft.volume=21&rft.issue=2&rft.spage=195&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fj.1365-2575.2009.00347.x","Open source software; Social capital; Studies; Open source; Open-source software; Computers--Computer Systems; Software development; 5240:Software & systems; Public domain; 9130:Experimental/theoretical; Effectiveness; Relational capital; Structural capital","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ''joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior.

Behind a successful oss project lies a community of actors, ranging from core developers to passive users, held together by a flexible governance structure and membership, leadership and contribution policies that align their interests. The motivation behind individuals participating in oss projects can be, among others, social, ideological, hedonistic, or signaling, while companies gain from their access to high-quality, innovative projects and an increase in their reputation and visibility. Nowadays many business models rely on oss as a product through the provision of associated services, or in coexistence with proprietary software, hardware, services, or licensing. The numerous oss licenses mainly differ on how they treat derived software: some contain provisions that maintain its availability in open source form while others allow more flexibility. Through its widespread adoption, oss is affecting the software industry, science, engineering, research, teaching, the developing countries, and the society at large through its ability to democratize technology and innovation.","2011","2025-04-25 15:24:19","2025-04-25 15:24:19","","187-347","","3-4","4","","","","","","","","","","English","","","ABI/INFORM Global","2695489045","","","Place: Hanover Publisher: Now Publishers Inc","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.atitle=Open+Source+Software%3A+A+Survey+from+10%2C000+Feet&rft.au=Androutsellis-Theotokis%2C+Stephanos%3BSpinellis%2C+Diomidis%3BKechagia%2C+Maria%3BGousios%2C+Georgios.&rft.aulast=Androutsellis-Theotokis&rft.aufirst=Stephanos&rft.date=2011-01-01&rft.volume=4&rft.issue=3-4&rft.spage=187&rft.isbn=&rft.btitle=&rft.title=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.issn=15719545&rft_id=info:doi/10.1561%2F0200000026","Open source software; Leadership; Information systems; Open source; Software engineering; Software license; Software; Open-source software; Psychology; Operations management; Computers--Information Science And Information Theory; Information management; Software development; Public domain; Freeware; Source code; Developing countries--LDCs; Software distribution; Proprietary software; Engineering education; Licensing (technology); Software licenses; Visibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at SourceForge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects.

This article considers the dynamics of value creation fuelling the proliferation of OSS and examines the business model factors that enable value capture. After interviewing leaders from over 20 OSS firms and organisations through early 2006, we found that three factors were consistently important in defining a vendor's adoption of a given business model: software licence choice, which takes into account intellectual property ownership; management of developer communities; and the unique features of the markets and product categories in which the vendor participates. Considering these factors, we characterise seven business models. One striking finding is that it is rare to find business-model purity. The majority of firms in our sample are pursuing either blended business models or multiple models simultaneously.

Drawing on impression-management literature, especially first-impression management, the authors explore the potential role that the initial presentation of new OSS projects plays in attracting developers. The article presents preliminary findings from a pilot study including interviews and an exploratory quantitative analysis for further research.

In this paper we examine how these employees' dual allegiance influences their knowledge sharing behaviour. We adopt Husted and Michailova's model on dual allegiance and knowledge sharing in inter-firm R&D collaborations to the context of open source software firms. We argue that the type of allegiance the individual holds towards their employing firm and the open source community has a strong influence of how they share knowledge with other community members. We use the examples of two open source software firms in New Zealand to ground the empirical inspiration of our paper and to illustrate our key ideas and arguments. We discuss the knowledge governance challenges imposed by employees' dual allegiance and how managers of open source software firms can balance the demands of the open source community and the interests of the clients.

In this article, the authors provide an overview of the project, along with some of the lessons learned and the challenges that remain. As a concept, HFOSS is clearly attractive to university computer science students and may help attract new students to computing. The HFOSS Project has expanded from its three initial schools, single corporate partner, and single software project into a vibrant community that today includes active faculty participants from eight US colleges and universities (and expressed interest from many more), industry representatives from five IT corporations, and ongoing software-development projects with two local nonprofit organizations and five international FOSS communities.","2009-08","2025-04-25 15:24:20","2025-04-25 15:24:20","","67","","8","52","","","","","","","","","","English","","","ABI/INFORM Global","237057193","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Revitalizing+Computing+Education+Through+Free+and+Open+Source+Software+for+Humanity&rft.au=Morelli%2C+Ralph%3BTucker%2C+Allen%3BDanner%2C+Norman%3Bde+Lanerolle%2C+Trishan+R%3BEllis%2C+Heidi+JC%3BIzmirli%2C+Ozgur%3BKrizanc%2C+Danny%3BParker%2C+Gary.&rft.aulast=Morelli&rft.aufirst=Ralph&rft.date=2009-08-01&rft.volume=52&rft.issue=8&rft.spage=67&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/","Open source software; Students; Software; Software development; 5240:Software & systems; Public domain; Software project management; United States--US; 9190:United States; Projects; 8306:Schools and educational services; College students; 61131:Colleges, Universities, and Professional Schools; Colleges & universities; Computers--Data Communications And Data Transmission Systems; Objectives; Progress","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.

However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives - voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study 1 investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

We suggest that the collaboration among maintainers tends to be influenced by different measures of code complexity.

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

However, different software systems follow different strategies to evolve, affecting both the release plan and the quality of these systems. In this paper, software evolution is considered as a self-organization process and the difference between closed-source software and open-source software is discussed in terms of self-organization. In particular, an empirical study of the evolution of Linux from version 2.4.0 to version 2.6.13 is reported. The study shows how open-source software systems self-organize to adapt to functional requirements and quality requirements.

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Building on information from an extensive dataset of secondary sources and 30 in-depth interviews, I show that de novo entrants have emerged in conjunction with a changing institutional infrastructure and a more pragmatic attitude toward firms that focus on technological benefits rather than ideology. To understand how these firms try to harness the work of these communities, I use the empirical data to derive a 2*2 matrix of different approaches. The X axis reflects whether or not the firms initiated a new community or relied on communities founded by peers, whereas the Y axis represents the degree of participation of the firm in the community. This taxonomy illustrates how de novo entrants are initiating new forms of communities or joining communities established by peers. This suggests that while many of the central pillars of FOSS remains, de novo entrants have emerged to find new ways of making business resulting in various implications for firm strategies and knowledge disclosure.

This manifests itself in the ability of open source communities to encourage critical peer review and the sharing of ideas. When these activities are important, the open source organizational form may do better than a proprietary organizational form. My results suggest why open source is particularly powerful when maintainability of software is critical, and also suggest that the founder of a software project may be more likely to choose open source if there is an existing dominant proprietary software project.

One way to achieve these ends is to implement eGovernment using free or open source software (FOSS). This will reduce dependence on software owned by major companies in developed countries. It could also promote an IP generating capacity in developing countries. An examination of the status of free or open source software in developing countries in Southeast Asia reveals that governments in these countries are aware of FOSS and wish to foster its use (but face considerable pressure to use proprietary software). This examination also reveals the presence of small but active groups seeking to develop and promote the use of free or open source software. This article is comprised of a discussion of FOSS (including that suitable for eGovernment), an explanation of the importance of FOSS for developing countries, a justification of governments centrality to the introduction of FOSS and a consideration of policies and initiatives undertaken by governments in developing countries in Southeast Asia.

From a constructionist perspective, the democratic effects of non-proprietary software are contingent on how the practice of free and open-source software is discursively represented and constituted as it is translated into new e-government systems. On these premises, an analysis of official discourse and government policy for non-proprietary software suggests that its introduction into government will bring more politics as usual rather than democratisation. Nevertheless, on the basis of an alternative discourse of ethics and freedom evident in the Free Software and Open Source communities, the authors of this paper envisage circumstances in which the discourse and practice of non-proprietary software contribute to opening-up and democratising e-government, by protecting and extending transparency and accountability in e-governments and by offering scope for technology to be shaped by citizens and associations as well as by administrators and private interests.

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-25 15:24:22","2025-04-25 15:24:22","","","","2","48","","","","","","","","","","English","","","ABI/INFORM Global","237056523","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Open+source+software+for+medical+image+processing+and+visualization&rft.au=Yoo%2C+Terry+S%3BAckerman%2C+Michael+J.&rft.aulast=Yoo&rft.aufirst=Terry&rft.date=2005-02-01&rft.volume=48&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/10.1145%2F1042091.1042120","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Research & development--R&D; United States--US; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Computers--Data Communications And Data Transmission Systems; Digital image processing; Image; Medical imaging","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Previous studies primarily touched on user activities in a few well-known open source projects but lack the empirical data to represent important issues facing the open source development community. This paper reports on a survey-based study that investigated user collaboration in open source development. Among the many interesting results, we found open source users themselves to be very experienced software developers. They are highly motivated to make their own contributions, work closely with developers on various tasks, and use electronic communication tools extensively. Users with different development experience and contributing to different category of projects tend to exhibit different motivations and behaviours. These findings confirm the differences between traditional and open source user collaboration and their implications for future open source evolution and management are given and discussed in this paper.

Working with data from the Apache and Mozilla projects, the study focuses on three aspects of open-source development. The first is the use of the open-source approach as a hedge against system complexity. The second is the adaptive learning mechanisms realized by the debugging process. The last is the learning curve effects of project-specific experience on bug cycle times. The results indicate that while open-source development is subject to positive learning effects, these effects are not universal, with some projects deriving more benefit than others.

First, the movement took off through the activity of a community that did not follow profit motivations. Second, a hierarchical co-ordination emerged without proprietary rights. Third, Open Source systems diffused in environments dominated by proprietary standard. The paper shows that recent developments in the theory of diffusion of technologies with network externality may help to explain these phenomena. A simulation model based on heterogeneous agents is developed in order to identify the relevant factors in the diffusion of the technology.

This model is efficient because of two related reasons: it avoids the inefficiencies of a strong intellectual property regime and it implements concurrently design and testing of software modules. The hazard of open-source is that projects can fork into competing versions. Open-source communities consist of governance structures that constitutionally minimize this danger.

We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors' uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors' motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms' sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms' sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer's OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer's projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.","2022-09","2025-04-25 15:25:17","2025-04-25 15:25:17","","867","","3","33","","","","","","","","","","English","","","ABI/INFORM Global","2718384104","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Flourish+or+Perish%3F+The+Impact+of+Technological+Acquisitions+on+Contributions+to+Open-Source+Software&rft.au=Chen%2C+Wei%3BJin%2C+Fujie%3BXue%2C+Ling.&rft.aulast=Chen&rft.aufirst=Wei&rft.date=2022-09-01&rft.volume=33&rft.issue=3&rft.spage=867&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2021.1086","Open source software; Uncertainty; Open source; Software; Open-source software; Computers--Information Science And Information Theory; Corporate governance; Project management; Public domain; Technological change; Innovations; Target acquisition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the lens of the integrative model of trust (IMoT), hypotheses regarding interactions between trust and community citizenship behaviors (CCBs – as OSSPC participating activities) are developed. Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust→CCBs and the CCBs→Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust→CCBs relationship. These findings are explained from several theoretical perspectives, which provide directions for future research and help community management to maintain sustained participation.","2022-09","2025-04-25 15:25:17","2025-04-25 15:25:17","","907-920","","5","62","","","","","","","","","","English","","","ABI/INFORM Global","2708632042","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Sustained+Participation+in+Open+Source+Software+Project+Communities&rft.au=Shi%2C+Zhengzhong%3BSun%2C+Hua.&rft.aulast=Shi&rft.aufirst=Zhengzhong&rft.date=2022-09-01&rft.volume=62&rft.issue=5&rft.spage=907&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2021.1949645","Open source software; Computers; Data analysis; Open source; Participation; Hypotheses; OSS; Software; diffusion of innovation; Trust; Public domain; Software project management; Qualitative analysis; Community participation; integrative model of trust; intellectual capital creation; social learning system; stage model; sustained participation; vector autoregressive model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

GaugeCam Remote Image Manager‐Educational 2 (GRIME2) is a mature, open‐source commercial friendly software application that automatically detects and measures water level in laboratory and field settings. The software relies on a dedicated target background for water line detection and image calibration. The system detects the change in pixel gray scale values associated with the intersection of the water level at the target surface. Fiducials on the target background are used to precisely create a pixel to real world coordinate transfer matrix and to correct for camera movement. The presented software package implements the algorithms and automates the water level measurement process, annotation of images with result overlays, creation of animations, and output of results to files that can be further analyzed in a spreadsheet or with R or Python. These GRIME2 features are illustrated using imagery from a coastal marsh field site. Tradeoffs between workflow and algorithm complexity and ease of use are discussed and future improvements are identified with the intention that this Findable, Accessible, Interoperable, and Reusable‐inspired software can be adopted, modified and improved by the user community. While image resolution, quality and other factors associated with field deployment (e.g., water surface roughness, sun glare, shadows, and bio‐fouling) will have an impact on measurement quality, previous controlled laboratory testing that did not manifest these issues showed potential for accuracy of ±3 mm (Gilmore et al., 2013, https://doi.org/10.1016/j.jhydrol.2013.05.011).","2022-08","2025-04-25 15:25:18","2025-04-25 15:25:18","","","","8","58","","","","","","","","","","English","","","ABI/INFORM Global","2707627947","","","Place: Washington Publisher: John Wiley & Sons, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Water+Resources+Research&rft.atitle=Technical+Note%3A+Open%E2%80%90Source+Software+for+Water%E2%80%90Level+Measurement+in+Images+With+a+Calibration+Target&rft.au=Chapman%2C+Kenneth+W%3BGilmore%2C+Troy+E%3BChapman%2C+Christian+D%3BBirgand%2C+Fran%C3%A7ois%3BMittelstet%2C+Aaron+R%3BHarner%2C+Mary+J%3BMehrubeoglu%2C+Mehrube%3BStranzl%2C+John+E%2C+Jr.&rft.aulast=Chapman&rft.aufirst=Kenneth&rft.date=2022-08-01&rft.volume=58&rft.issue=8&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Water+Resources+Research&rft.issn=00431397&rft_id=info:doi/10.1029%2F2022WR033203","Open source software; open source software; Quality assurance; Software; Software packages; Measurement; Imagery; Software development; Algorithms; Environmental; Laboratories; Workflow; Digital image processing; Annotations; Calibration; Coastal marshes; Earth Sciences--Hydrology; hydrology; image processing; Image processing; Image quality; Image resolution; Laboratory tests; pixel to world calibration; Pixels; Shadows; stage measurement; Surface roughness; Tidal marsh; Transfer matrices; Water; Water level; Water level measurement; Water levels; waterline detection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, this research has focused mainly on social/cultural factors, neglecting the software tools and infrastructure. To shed light on how OSS tools and infrastructure might factor into OSS barriers to entry, we conducted two studies: (1) a field study with five teams of software professionals, who worked through five use cases to analyze the tools and infrastructure used in their OSS projects; and (2) a diary study with 22 newcomers (9 women and 13 men) to investigate whether the barriers matched the ones identified by the software professionals. The field study produced a bleak result: software professionals found gender biases in 73 percent of all the newcomer barriers they identified. Further, the diary study confirmed these results: Women newcomers encountered gender biases in 63 percent of barriers they faced. Fortunately, many kinds of barriers and biases revealed in these studies could potentially be ameliorated through changes to the OSS software environments and tools.","2022","2025-04-25 15:25:18","2025-04-25 15:25:18","","241-259","","1","48","","","","","","","","","","English","","","ABI/INFORM Global","2619023727","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=How+Gender-Biased+Tools+Shape+Newcomer+Experiences+in+OSS+Projects&rft.au=Padala%2C+Hema+Susmita%3BMendez%2C+Christopher%3BFronchetti%2C+Felipe%3BSteinmacher%2C+Igor%3BSteine-Hanson%2C+Zoe%3BHilderbrand%2C+Claudia%3BHorvath%2C+Amber%3BHill%2C+Charles%3BSimpson%2C+Logan%3BBurnett%2C+Margaret%3BGerosa%2C+Marco%3BSarma%2C+Anita.&rft.aulast=Padala&rft.aufirst=Hema&rft.date=2022-01-01&rft.volume=48&rft.issue=1&rft.spage=241&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2020.2984173","Open source software; Infrastructure; newcomers; gender; Productivity; software engineering; Software; Open-source software; Tools; diversity; Documentation; Open source software (OSS); Cultural differences; Computers--Software; Software development tools; Gender; Diary studies; Field study; Human bias; Men; Problem-solving; Sexism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted a policy Delphi study involving 24 FLOSS community managers from 22 different communities. Our panel identified 16 concerns related to managing EV in FLOSS, which we ranked by prevalence. We also describe 65 practices for managing EV in FLOSS. Almost three-quarters of these practices are used by at least three community managers.

Network connections provide access to external knowledge in the community; the absorption and transfer of this new knowledge require appropriate internal knowledge and developer roles. With longitudinal data collected from 4,518 open source software development projects hosted at SourceForge, the authors show that knowledge breadth (depth) helps with the absorption of external knowledge achieved from network depth (breadth), but it inhibits the absorption of external knowledge obtained from network breadth (depth). Further, developer roles (e.g., bridge members, role diversity) can mitigate the negative consequences of suboptimal combinations and facilitate effective transfers of absorbed external knowledge across and within projects. These findings provide important theoretical and managerial implications for managing network connections, knowledge, and developer roles in open source software communities.","2020-12","2025-04-25 15:25:18","2025-04-25 15:25:18","","1651","","4","44","","","","","","","","","","English","","","ABI/INFORM Global","2472175612","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=More+Is+Not+Necessarily+Better%3A+An+Absorptive+Capacity+Perspective+on+Network+Effects+in+Open+Source+Software+Development+Communities&rft.au=Tang%2C+Tanya+%28Ya%29%3BFang%2C+Eric%28+Er%29%3BQualls%2C+William+J.&rft.aulast=Tang&rft.aufirst=Tanya&rft.date=2020-12-01&rft.volume=44&rft.issue=4&rft.spage=1651&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F13991","Open source software; Computers; Open source; Knowledge; Knowledge management; Social networks; Software development; Public domain; Network effect; Absorption; Absorptive capacity; Absorptivity; Knowledge acquisition; Knowledge community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although many data scientists and the high-performing companies that employ them seem to have developed robust methods to employ data sciences practices to achieve competitive advantages, there have been few attempts at defining and explaining how and why data science helps firms to achieve desired outcomes. In this paper, we describe how data science, which combines computer programming, domain knowledge, and analytic skillsets to scientifically extract insights from data, can be used to help meet the growing demand of analytic needs across an organization's value chain. This is done through the illustration of an applied data science initiative to a strategic sourcing problem via the use of open-source technology. In doing so, we contribute to the growing data science literature by demonstrating the application of unique data science capabilities. Moreover, the paper provides a tutorial on how to use a specific R package along with an actual case in which that package use used.","2020-10","2025-04-25 15:25:18","2025-04-25 15:36:15","","1","","","54","","","","","","","","","","English","","","ABI/INFORM Global","2505725296","","","Place: Kidlington Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Management&rft.atitle=A+data+science+and+open+source+software+approach+to+analytics+for+strategic+sourcing%3A+SSIS&rft.au=Boehmke%2C+Brad%3BHazen%2C+Benjamin%3BBoone%2C+Christopher+A%3BRobinson%2C+Jessica+L.&rft.aulast=Boehmke&rft.aufirst=Brad&rft.date=2020-10-01&rft.volume=54&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Management&rft.issn=02684012&rft_id=info:doi/10.1016%2Fj.ijinfomgt.2020.102167","Science; Open source software; Open-source software; Data science; Social Sciences: Comprehensive Works; Competitive advantage; Mathematical analysis; Computer programming; Skills; Analytics; R package; Sourcing; Strategic sourcing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 15:25:19","2025-04-25 15:25:19","","1439","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2447305472","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Takeoff+of+Open+Source+Software%3A+A+Signaling+Perspective+Based+on+Community+Activities&rft.au=Setia%2C+Pankaj%3BBayus%2C+Barry+L%3BRajagopalan%2C+Balaji.&rft.aulast=Setia&rft.aufirst=Pankaj&rft.date=2020-09-01&rft.volume=44&rft.issue=3&rft.spage=1439&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F12576","Open source software; Computers; Open source; Software; Open-source software; Signaling; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Faced with such challenges of increasingly complicated software design, large-scale refactoring that radically restructures the architecture of the software can be one of the solutions. In this study, we investigate and illustrate how OSS contributors accomplish large-scale refactoring in OSS development in which there is no significant corporate participation. In our observations, as the costs of coordination requirements rise, OSS contributors increase coordination capability to manage dependencies among multiple sources during the large-scale refactoring periods. Our findings suggest that OSS contributors episodically use traditional coordination mechanisms during the large-scale refactoring periods. Our study provides actionable insights into how OSS contributors make joint action that cannot be achieved by individuals working independently and use the provision of rewards in order to achieve a shared, explicit goal of large-scale refactoring.","2020","2025-04-25 15:25:19","2025-04-25 15:25:19","","150-184","","2","2","","","","","","","","","","English","","","ABI/INFORM Global","2453844031","","","Place: Geneva Publisher: Inderscience Enterprises Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Systems+and+Management&rft.atitle=Large-scale+refactoring+challenges+and+coordination+in+open+source+software+development&rft.au=Moon%2C+Eunyoung%3BHowison%2C+James.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2020-01-01&rft.volume=2&rft.issue=2&rft.spage=150&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Systems+and+Management&rft.issn=17513227&rft_id=info:doi/10.1504%2FIJISAM.2020.110552","Open source software; online communities; open source; Open source; coordination; Open-source software; Coordination; Computers--Information Science And Information Theory; Software development; Public domain; Code refactoring; collaborative work; Reward; software refactoring","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, these infrequent volunteers contribute to the sustainability of FLOSS projects, and should ideally be encouraged to continue participating, even if they cannot be persuaded to contribute regularly. Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature. Also, episodic volunteers make a wide range of value-added contributions other than code, and they should neither be expected nor coerced into becoming habitual volunteers.","2020","2025-04-25 15:25:19","2025-04-25 15:25:19","","962-980","","9","46","","","","","","","","","","English","","","ABI/INFORM Global","2444610198","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Uncovering+the+Periphery%3A+A+Qualitative+Survey+of+Episodic+Volunteering+in+Free%2FLibre+and+Open+Source+Software+Communities&rft.au=Barcomb%2C+Ann%3BKaufmann%2C+Andreas%3BRiehle%2C+Dirk%3BKlaas-Jan+Stol%3BFitzgerald%2C+Brian.&rft.aulast=Barcomb&rft.aufirst=Ann&rft.date=2020-01-01&rft.volume=46&rft.issue=9&rft.spage=962&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2018.2872713","Open source software; Community; Qualitative research; free software; open source software; Software; Open-source software; Task analysis; Volunteers; Community management; Companies; Sustainable development; Public domain; Freeware; Computers--Software; Lenses; Free and open-source software; episodic volunteering; Volunteering; peripheral developer; Periphery","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We consider two types of followers: developers (those directly involved in software development) and observers (those indirectly involved in it). We conduct a series of empirical investigations by using a longitudinal dataset of OSS projects hosted in GitHub, along with a survey and qualitative data. We find that followership can affect code reuse, but the effect depends on the nature of the follower (developer or observer). Overall, our study suggests that followership is important for code reuse in OSS because it enables participants to learn, and learning promotes code reuse.","2019-12","2025-04-25 15:25:19","2025-04-25 15:25:19","","1303","","4","43","","","","","","","","","","English","","","ABI/INFORM Global","2319173778","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Followership+in+an+Open-Source+Software+Project+and+its+Significance+in+Code+Reuse&rft.au=Jiang%2C+Qiqi%3BTan%2C+Chuan-Hoo%3BSia%2C+Choon+Ling%3BWei%2C+Kwok+Kee.&rft.aulast=Jiang&rft.aufirst=Qiqi&rft.date=2019-12-01&rft.volume=43&rft.issue=4&rft.spage=1303&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2019%2F14043","Open source software; Computers; Open source; Software; Open-source software; Software development; Public domain; Software project management; Software upgrading; Source code; Code reuse; Qualitative analysis; Computer programming; Datasets; Followership","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While working on OSS projects contributors acquire project related individualistic knowledge and gain experience and skills, which often remains unshared with others and is usually lost once contributors leave a project. All software development organisations face the problem of knowledge loss as employees leave, but this situation is exasperated in OSS projects where most contributors are volunteers with largely unpredictable engagement durations. Contributor turnover is inevitable due to the transient nature of OSS project workforces causing knowledge loss, which threatens the overall sustainability of OSS projects and impacts negatively on software quality and contributor productivity. Objective: The objective of this work is to deeply and systematically investigate the phenomenon of knowledge loss due to contributor turnover in OSS projects as presented in the state-of-the-art literature and to synthesise the information presented on the topic. Furthermore, based on the learning arising from our investigation it is our intention to identify mechanisms to reduce the overall effects of knowledge loss in OSS projects. Methodology: We use the snowballing methodology to identify the relevant literature on knowledge loss due to contributor turnover in OSS projects. This robust methodology for a literature review includes research question, search strategy, inclusion, exclusion, quality criteria, and data synthesis. The search strategy, and inclusion, exclusions and quality criteria are applied as a part of snowballing procedure. Snowballing is considered an efficient and reliable way to conduct a systematic literature review, providing a robust alternative to mechanically searching individual databases for given topics. Result: Knowledge sharing in OSS projects is abundant but there is no evidence of a formal strategy or practice to manage knowledge. Due to the dynamic and diverse nature of OSS projects, knowledge management is considered a challenging task and there is a need for a proactive mechanism to share knowledge in the OSS community for knowledge to be reused in the future by the OSS project contributors. From the collection of papers found using snowballing, we consolidated various themes on knowledge loss due to contributor turnover in OSS projects and identified 11 impacts due to knowledge loss in OSS projects, and 10 mitigations to manage with knowledge loss in OSS projects. Conclusion: In this paper, we propose future research directions to investigate integration of proactive knowledge retention practices with the existing OSS practices to reduce the current knowledge loss problem. We suggest that there is insufficient attention paid to KM in general in OSS, in particular there would appear to an absence of proactive measures to reduce the potential impact of knowledge loss. We also propose the need for a KM evaluation metric in OSS projects, similar to the ones that evaluate health of online communities, which should help to inform potential consumers of the OSS of the KM status on a project, something that is not existent today.","2019-06","2025-04-25 15:25:19","2025-04-25 15:25:19","","104","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2221225951","","","Place: Kidlington Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Management&rft.atitle=A+systematic+examination+of+knowledge+loss+in+open+source+software+projects%3A+SSIS&rft.au=Rashid%2C+Mehvish%3BClarke%2C+Paul+M%3BO%E2%80%99Connor%2C+Rory+V.&rft.aulast=Rashid&rft.aufirst=Mehvish&rft.date=2019-06-01&rft.volume=46&rft.issue=&rft.spage=104&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Management&rft.issn=02684012&rft_id=info:doi/10.1016%2Fj.ijinfomgt.2018.11.015","Open source software; Open source; Software; Open-source software; Strategy; Knowledge management; Methodology; Project management; Software development; Software quality; Systematic review; Public domain; Software Projects; Investigations; Social Sciences: Comprehensive Works; Literature reviews; Geographical distribution; Search methods; Snowballing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study measures the firm-level productivity impact of nonpecuniary (free) OSS and finds a positive and significant value-added return for firms that have an ecosystem of complementary capabilities. There is no such impact for firms without this ecosystem of complements. Dynamic panel analysis, instrumental variables, and a variety of robustness checks are used to address measurement error concerns and to add support for a more causal interpretation of the results. For firms with an ecosystem of complements, a 1% increase in the use of nonpecuniary OSS leads to an increase in value-added productivity of between 0.002% and 0.008%. This effect is smaller for larger firms, and the results indicate that prior research underestimates the amount of IT firms use.","2019-03","2025-04-25 15:25:19","2025-04-25 15:25:19","","1191","","3","65","","","","","","","","","","English","","","ABI/INFORM Global","2198542297","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+Science&rft.atitle=Open+Source+Software+and+Firm+Productivity&rft.au=Nagle%2C+Frank.&rft.aulast=Nagle&rft.aufirst=Frank&rft.date=2019-03-01&rft.volume=65&rft.issue=3&rft.spage=1191&rft.isbn=&rft.btitle=&rft.title=Management+Science&rft.issn=00251909&rft_id=info:doi/10.1287%2Fmnsc.2017.2977","Open source software; Productivity; Open source; Software; Open-source software; Measurement; Companies; Financial performance; Robustness; Public domain; Business And Economics--Labor And Industrial Relations; Economic value added; Instrumental variables estimation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Then, the detection rate and remaining faults of previous release are considered in the modeling and analysis of reliability of the current release. The optimal version-update time is computed using multi-attribute utility theory for these software systems, considering the two main utility factors, namely, rapid release strategy and level of reliability.

Often this takes the form of company employees devoting their time to contribute code to the efforts of projects in these communities. Ideology has traditionally served to motivate, coordinate, and guide volunteer contributions to OSS communities. As employees represent an increasing proportion of the participants in OSS communities, the role of OSS ideology in guiding their commitment and code contributions is unknown. In this research, we argue that OSS ideology misfit has important implications for companies and the OSS communities to which their employees contribute, since their engagement in such communities is not necessarily voluntary. We conceptualize two different types of misfit: OSS ideology under-fit, whereby an employee embraces an OSS ideology more than their coworkers or OSS community do, and OSS ideology over-fit, whereby an employee perceives that their coworkers or OSS community embrace the OSS ideology more strongly than the employee does. To develop a set of hypotheses about the implications of these two types of misfit for employee commitment to the company and commitment to the OSS community, we draw on self-determination theory. We test the hypotheses in a field study of 186 employees who participate in an OSS community. We find that OSS ideology under-fit impacts the company and the community in the same way: it decreases employee commitment to the company and commitment to the OSS community. In contrast, we find that OSS ideology over-fit increases commitment to the company but decreases commitment to the OSS community. Finally, we find that employees’ commitment to their company reinforces the impact of their commitment to the OSS community in driving ongoing code contributions. This provides a holistic view of OSS ideology and its impacts among an increasingly pervasive yet understudied type of participant in OSS research. It provides insights for companies that are considering assigning their employees to work in OSS communities as well as for OSS communities that are partnering with these companies.","2018-12","2025-04-25 15:25:19","2025-04-25 15:25:19","","1069","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2136026232","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Impact+of+Ideology+Misfit+on+Open+Source+Software+Communities+and+Companies&rft.au=Daniel%2C+Sherae+L%3BMaruping%2C+Likoebe+M%3BCataldo%2C+Marcelo%3BHerbsleb%2C+Jin.&rft.aulast=Daniel&rft.aufirst=Sherae&rft.date=2018-12-01&rft.volume=42&rft.issue=4&rft.spage=1069&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/","Open source software; Computers; Open source; Hypotheses; Software; Open-source software; Commitment; Impact analysis; Public domain; Employees; Software services; Community participation; Ideology; Self-determination","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A series of hypotheses about how distributed innovation (independent variables) influences knowledge sharing (mediating variable) and then affects the performance of OSS projects (dependent variable) are tested and approved. On the one side, we argue that developers will actively affect knowledge sharing in terms of participative motivation, social network and organisational culture. On the other hand, users may also affect the knowledge sharing when considering innovation willingness and capacity. It is interesting to find that social network is the most important factor in Chinese cases.

In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience.

In this research, we advance on such studies through an integrated FLOSS evaluation-selection model with a risk-based decision-making approach. Our model was built upon the other two literatures, and it was structured as a multi-attribute decision-making (MADM) model which contains 12 variables grouped in four risk categories: financial, organisational, end user, and technical ones. We illustrated its utilisation in the domain of information technology service management (ITSM) FLOSS tools. Hence, our model contributes to the FLOSS literature with the inclusion of the risk management approach and to the FLOSS evaluation-selection praxis with the provision of an innovative and essential risk-based model.","2016","2025-04-25 15:25:20","2025-04-25 15:25:20","","326","","4","16","","","","","","","","","","English","","","ABI/INFORM Global","1861798477","","","Place: Geneva Publisher: Inderscience Enterprises Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Technology+Policy+and+Management&rft.atitle=An+MADM+risk-based+evaluation-selection+model+of+free-libre+open+source+software+tools&rft.au=Mora%2C+Manuel%3BG%C3%B3mez%2C+Jorge+Marx%3BO%27Connor%2C+Rory+V%3BGelman%2C+Ovsei.&rft.aulast=Mora&rft.aufirst=Manuel&rft.date=2016-10-01&rft.volume=16&rft.issue=4&rft.spage=326&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Technology+Policy+and+Management&rft.issn=14684322&rft_id=info:doi/","Open source software; Decision making; Information technology; Studies; Open source; Software; Risk management; Programming tool; Technology: Comprehensive Works; Decision making models; IT service management; Multiple criteria decision making","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These decisions formed a coherent IP strategy in support of OSS. We find that IBM's actions stimulated new OSS product introductions by entrepreneurial firms and that their impact is increasing in the cumulativeness of innovation in the market and the extent to which patent ownership in the market is concentrated.","2016-09","2025-04-25 15:25:20","2025-04-25 15:25:20","","2668","","9","62","","","","","","","","","","English","","","ABI/INFORM Global","2677663077","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+Science&rft.atitle=Opening+Up+Intellectual+Property+Strategy%3A+Implications+for+Open+Source+Software+Entry+by+Start-up+Firms&rft.au=Wen%2C+Wen%3BCeccagnoli%2C+Marco%3BForman%2C+Chris.&rft.aulast=Wen&rft.aufirst=Wen&rft.date=2016-09-01&rft.volume=62&rft.issue=9&rft.spage=2668&rft.isbn=&rft.btitle=&rft.title=Management+Science&rft.issn=00251909&rft_id=info:doi/10.1287%2Fmnsc.2015.2247","Open source software; Innovation; Open source; Open-source software; Ownership; Patents; Companies; Intellectual property; Strategic planning; Innovations; Business And Economics--Labor And Industrial Relations; Startups; Patent; Company; Patent law","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It has been suggested that such small-scale and home-grown solutions (e.g. mobile phone apps), usually championed by social enterprises (SEs), are more likely to introduce pro-poor change than infrastructure heavy ICr initiatives designed by state and other international actors. In the Indian context, FOSS-based social innovations (Sis) introduced by SEs are helping poor communities tackle previously thought-to-be unresolvable socio-economic problems. An interesting question, therefore, would be: in what ways is the SE model and approach uniquely equipped to develop FOSS-based Sis that deliver pro-poor change? The empirical component of the research attempts to shed light on this question by uncovering the nuts and bolts of the development methodology deployed by an SE during the coding and launch of an FOSS-based SI. Findings highlight the significant role of the founder's social vision; the challenges of accurately capturing and translating to software developers the nature and nuance of social problems; and, the incumbent issues in putting together a methodology that creates active user engagement throughout the software development process, overcoming difficult barriers such as language and culture.","2016-07","2025-04-25 15:25:20","2025-04-25 15:25:20","","28","","","52/53","","","","","","","","","","English","","","ABI/INFORM Global","1798370797","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technovation&rft.atitle=Social+innovation+with+open+source+software%3A+User+engagement+and+development+challenges+in+India&rft.au=Bhatt%2C+Punita%3BAhmad%2C+Ali+J%3BRoomi%2C+Muhammad+Azam.&rft.aulast=Bhatt&rft.aufirst=Punita&rft.date=2016-06-01&rft.volume=52%2F53&rft.issue=&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technovation&rft.issn=01664972&rft_id=info:doi/","Open source software; Innovation; India; Studies; User behavior; Open source; 9130:Experiment/theoretical treatment; 9179:Asia & the Pacific; 8302:Software & computer services industry; Innovations; Technology: Comprehensive Works; 1220:Social trends & culture; 7100:Market research; Software services; Developing country; Social innovation; Customer engagement; Social change; Social enterprise","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The increased participation is an observable phenomenon; many researchers and practitioners assume that the practice of community sharing does not improve the bottom line, but rather believe the practice is altruistic in nature. Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, ""Why do for-profit corporations participate in the development of open source software?"" was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory. In this article, we examine interview responses and field study data from corporate members of open source communities to determine how they justify devoting time and effort to community engagement. Our study makes a contribution to open source software literature by revealing that numerous rational and emotional reasons exist for corporate participation in open source software development.","2016","2025-04-25 15:25:20","2025-04-25 15:25:20","","323-343","","4","26","","","","","","","","","","English","","","ABI/INFORM Global","1830348270","","","Place: Mahwah Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.atitle=Game+theory+and+open+source+contribution%3A+Rationale+behind+corporate+participation+in+open+source+software+development&rft.au=Kendall%2C+Julie+E.%3BKendall%2C+Kenneth+E.%3BGermonprez%2C+Matt.&rft.aulast=Kendall&rft.aufirst=Julie&rft.date=2016-01-01&rft.volume=26&rft.issue=4&rft.spage=323&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.issn=10919392&rft_id=info:doi/10.1080%2F10919392.2016.1228360","Open source software; Open source; open source software; Participation; Software; Open-source software; Game theory; open source communities; Software development; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; 9130:Experimental/theoretical; 2600:Management science/operations research; Business And Economics--Computer Applications; Cooperative game; Coopetition; Drama Theory; game theory","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the current work we investigate software licensing giving a critical and comparative overview of existing assistive approaches and tools. These approaches are centered on three main categories: license information identification from source code and binaries, software metadata stored in code repositories, and license modeling and associated reasoning actions.

We show that, contrary to standard predictions, additional contribution to the public good by the government or a new market entrant can lead to higher investments of all incumbent firms, that is, a crowding-in effect. This result occurs if the investment cost function is superadditive. We find that government contribution leads to larger crowding-in effects than subsidizing market entry if the price elasticity of demand with respect to the private good is large relative to the one with respect to the public good.

However, the incomplete understanding of the phenomenon has continued to prompt researchers to investigate factors that could increase the use and popularity of open source software (OSS). While a key antecedent for OSS use highlighted in the previous literature is the software quality, we propose that effective online user support is also necessary to increase its popularity. As an understudied area, this paper seeks to understand the role of online user support networks in facilitating OSS use. Based on the network embeddedness theory, it suggests that properties of the user support network i.e., variation in structural and junctional embeddedness, measured as the in-degree and betweenness centralizations respectively, would affect OSS popularity in terms of the number of active users and downloads of the software. Testing on a sample of 176 OSS projects from Sourceforge.net, we showed that a negative quadratic relationship exists between the variation in structural embeddedness of the OSS user support network and the software popularity. Further, as hypothesized, the variation in junctional embeddedness was found to positively impact the OSS popularity. Theoretical and practical implications of the study are discussed.","2014-08","2025-04-25 15:25:20","2025-04-25 15:25:20","","142","","","64","","","","","","","","","","English","","","ABI/INFORM Global","1558315974","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Decision+Support+Systems&rft.atitle=Uncovering+the+relationship+between+OSS+user+support+networks+and+OSS+popularity&rft.au=Sutanto%2C+Juliana%3BKankanhalli%2C+Atreyi%3BTan%2C+Bernard+CY.&rft.aulast=Sutanto&rft.aufirst=Juliana&rft.date=2014-08-01&rft.volume=64&rft.issue=&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=Decision+Support+Systems&rft.issn=01679236&rft_id=info:doi/","Open source software; Studies; Open-source software; Social networks; Software quality; 5240:Software & systems; 9130:Experiment/theoretical treatment; Computers--Automation; User services; Mathematical models; Proprietary","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In doing so, it offers new insights into the association between open innovation and diversification. We rely on arguments inspired by the literature and evidence collected through interviews with OSS SMEs' top managers to investigate factors that favor or hinder within-industry diversification. First, in line with the mainstream diversification literature, we focus attention on the role of firm size. Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products. Furthermore, we provide preliminary evidence that the practice of authorizing firm programmers to contribute autonomously to OSS projects of their own choice during working hours may be positively associated to within-industry diversification only if OSS SMEs possess adequate internal technological resources.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-25 15:25:21","2025-04-25 15:25:21","","127-143","","2","39","","","","","","","","","","English","","","ABI/INFORM Global","1929783648","","","Place: Ahmedabad Publisher: Sage Publications, New Delhi India","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Vikalpa&rft.atitle=The+Emergence+of+an+Organizational+Field%3A+The+Case+of+Open+Source+Software&rft.au=Ojha%2C+Abhoy+K%3BRao%2C+Ravi+Anand.&rft.aulast=Ojha&rft.aufirst=Abhoy&rft.date=2014-04-01&rft.volume=39&rft.issue=2&rft.spage=127&rft.isbn=&rft.btitle=&rft.title=Vikalpa&rft.issn=02560909&rft_id=info:doi/10.1177%2F0256090920140211","Open source software; Business And Economics--Management; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Adopting a sociolinguistic perspective, we conceptualize group maintenance behavior as interpersonal communication tactics -- specifically, social presence and politeness tactics -- that help maintain relationships among group members. Developer email messages were collected from two FLOSS projects with different development statuses, and their content was analyzed to identify frequently used group maintenance tactics. We then compared the group maintenance tactics used in the two projects, finding differences that reflect changes in the project work practices. Our work theoretically contributes to FLOSS research and has practical implications for FLOSS practitioners.

Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving. We discuss the applicability of relational events models in organizational research.

In doing so, we consider the content of potential information flows within the network and argue that the impact of network structure on technology adoption can be better understood by separately examining its impact from two groups of alters-current and potential adopters. We contend that increased network centrality and closure among current adopters contribute positively to adoption, whereas the same among potential adopters has exactly the opposite impact. Accordingly, we propose a dynamic view where the fraction of current adopters in the network positively moderates the impact of network centrality and closure. We empirically test the theory by analyzing the adoption of software version control technology by open source software projects. Our results strongly support the theory.

In recent years, firms motivated by revenues from software services markets have become the primary contributors to open-source development. In this paper we study the role of services in open source software development and explore the choice between open source and proprietary software. Specifically, our economic model jointly analyzes the investment and pricing decisions of the originators of software and of subsequent open-source contributors. We find that if a contributor is efficient in software development, the originator should adopt an open-source strategy, allowing the contributor to offer higher total quality and capture the higher end of the market while the originator focuses on providing software services to lower end consumers. Conversely, if the contributor is not efficient in development, the originator should adopt a proprietary software development strategy, gaining revenue from software sales and squeezing the contributor out of the services market. In certain cases an increase in originator development efficiency can result in increased contributor profits. Finally, we find that, somewhat counterintuitively, an increase in contributor development efficiency can reduce overall social welfare.

The current findings support the argument that OSS-adopting organizations can be clearly distinguished from their non-adopting counterparts in terms of their availability of internal OSS human capital, accessibility to external OSS human capital, organizational size, IT department size, and criticality of IT operation.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated 'copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the 'new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11","2025-04-25 15:25:21","2025-04-25 15:25:21","","597-625","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2089824849","","","Place: Abingdon Publisher: Taylor & Francis LLC","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Free software; Property; Capitalism; Economic theory; Free and open-source software; Profitability; Profits; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the US. This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? The authors interviewed the CIO, or equivalent position, at 17 not-for-profit and public hospitals across the US. Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk.","2013-12","2025-04-25 15:25:21","2025-04-25 15:25:21","","361","","4","38","","","","","","","","","","English","","","ABI/INFORM Global","1435635391","","","Place: Frederick Publisher: Lippincott Williams & Wilkins Ovid Technologies","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Health+Care+Management+Review&rft.atitle=The+use+and+role+of+open+source+software+applications+in+public+and+not-for-profit+hospitals+in+the+United+States&rft.au=Vest%2C+Joshua+R%3BStephens%2C+James+H.&rft.aulast=Vest&rft.aufirst=Joshua&rft.date=2013-10-01&rft.volume=38&rft.issue=4&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=Health+Care+Management+Review&rft.issn=03616274&rft_id=info:doi/","Open source software; Studies; Open source; Open-source software; Technology adoption; Hospitals; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; United States--US; 9190:United States; Cost control; Nonprofit organizations; Public; Nonprofit organization; 62211:General Medical and Surgical Hospitals; 8320:Health care industry; Health Facilities And Administration; Hospital; Medical technology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Following a cohort of OSS programmers over a six-year period, they empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, their findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18% increase in wages. Moreover, they find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management.","2013-09","2025-04-25 15:25:22","2025-04-25 15:42:36","","520-538,879,881","","3","24","","","","","","","","","","English","","","ABI/INFORM Global","1445136928","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=All+Are+Not+Equal%3A+An+Examination+of+the+Economic+Returns+to+Different+Forms+of+Participation+in+Open+Source+Software+Communities&rft.au=Hann%2C+Il-Horn%3BRoberts%2C+Jeffrey+A%3BSlaughter%2C+Sandra+A.&rft.aulast=Hann&rft.aufirst=Il-Horn&rft.date=2013-09-01&rft.volume=24&rft.issue=3&rft.spage=520&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/","Open source software; Studies; Productivity; Open source; Participation; Hypotheses; Software; Open-source software; Computers--Information Science And Information Theory; Internet; Project management; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; United States--US; 9190:United States; 1130:Economic theory; Employment; Labor economics; Labor market; Workers; Signal; Absenteeism; Employers; Performance; Wage; Wages & salaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Their results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its interproject social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. Finally, they find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license.","2013-09","2025-04-25 15:25:22","2025-04-25 15:25:22","","539-560,880-881","","3","24","","","","","","","","","","English","","","ABI/INFORM Global","1445136834","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Networks%2C+Social+Influence%2C+and+the+Choice+Among+Competing+Innovations%3A+Insights+from+Open+Source+Software+Licenses&rft.au=Singh%2C+Param+Vir%3BPhelps%2C+Corey.&rft.aulast=Singh&rft.aufirst=Param&rft.date=2013-09-01&rft.volume=24&rft.issue=3&rft.spage=539&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/","Open source software; Studies; Open source; Software license; Open-source software; Licenses; License; Social influence; Computers--Information Science And Information Theory; Project management; Social networks; Network; Software development; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; Technological change; Innovations; United States--US; 9190:United States; Licensing; Employees; 5250:Telecommunications systems & Internet communications; Employers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We approach these adoption challenges as a problem of gaining support for organizational innovation. Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are -- on average -- more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect. Suggestions for PCSS firms are presented and implications for innovation literature are discussed.

Interest in Spatial Databases is, however, more widespread - especially with the increasing understanding of the relevance of geospatial techniques to fields as diverse as anthropology and architecture. This article describes the development and evaluation of a self-paced hands-on course on Databases and Spatial Databases for CEGE students, presented to students to complement and enhance in-class teaching. The article focuses on both pedagogical elements of self-paced learning and the suitability of Free and Open Source Software and Open Data (PostgreSQL/PostGIS, Quantum GIS, Open Street Map) for the Spatial Databases curriculum. The resulting material was evaluated by a cohort of 25 students in 2010, and their feedback (very positive) and the overall results provide an interesting insight into suitable methods to employ when teaching technical subjects to a cohort having differing background skill levels.

Although researchers have studied some predictors of OSS project performance, there is a lack of empirical work that studies the impact of project capabilities on the performance of OSS projects. Therefore, this paper studies project capabilities as potential predictors of OSS project performance. The data, gathered from 607 OSS projects over time (in two snap-shots), were consistent with Dynamic Capability Theory (DCT). In other words, the results showed that in order to achieve higher project performance, OSS projects need to have strong capabilities in terms of proactive and efficient defect-removal as well as proactive and efficient functionality-enhancement. The implications of these results for the OSS research community are discussed, followed by recommendations for OSS practitioners.

However, while there is no shortage on research on individuals' motivation for contributing to open source, few have investigated the commercial companies' motivations for doing the same. A case study was conducted at three different companies from the IT service industry, to investigate three possible drivers: sale of complimentary services, innovation and opensourcing (outsourcing). We offer three conclusions. First, we identified three main drivers for contributing to open source, which are (a) selling complimentary services, (b) building greater innovative capability and (c) cost reduction through opensourcing to an external community. Second, while previous research has documented that the most important driver is selling complimentary services, we found that this picture is too simple. Our evidence points to a broader set of motivations, in the sense that all our cases exhibit combinations of the three drivers. Finally, our findings suggest that there might be a shift in how commercial companies view open source software. The companies interviewed have all expressed a moral obligation to contribute to open source.

The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.","2012-04","2025-04-25 15:25:23","2025-04-25 15:25:23","","920","","4","85","","","","","","","","","","English","","","ABI/INFORM Global","925777279","","","Place: New York Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Systems+and+Software&rft.atitle=Free+and+Open+Source+Software+versus+Internet+content+filtering+and+censorship%3A+A+case+study&rft.au=Shirazi%2C+Farid.&rft.aulast=Shirazi&rft.aufirst=Farid&rft.date=2012-04-01&rft.volume=85&rft.issue=4&rft.spage=920&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Systems+and+Software&rft.issn=01641212&rft_id=info:doi/","Open source software; Studies; Censorship; Open source; Software packages; Internet; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Computers--Software; Free and open-source software; Systems design; 9178:Middle East; Filtering software; Iran","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nonetheless, scholars have never tested this assertion. This paper takes a first step toward filling this gap. First, based on the high-tech entrepreneurship literature and the OSS research stream, we illustrate why collaborations with the OSS community should exert a positive effect on entrepreneurial ventures' innovation performance. Then, we provide a rigorous quantitative analysis of the innovation impact of these collaborations. Our econometric estimates indicate that entrepreneurial ventures collaborating with the OSS community exhibit superior innovation performance compared with their noncollaborating peers.

Compared with the prevailing proprietary approaches, open-source software products are developed by co-opting external developers and prospective users. Although a core group of developers might still play a key role in the initial design and development, a notable aspect of the open-source software paradigm is the role of peripheral developers in the enhancement and popularization of the product. Peripheral developers are not formal members of the core development team. They voluntarily contribute their time and creative talent in improving the quality of the product or in popularizing the product through word-of-mouth advocacy. As volunteers, they are not subject to the traditional hierarchical controls, nor are they contractually obligated. Peripheral developers represent a novel and unique aspect of open-source software development, and there is a greater interest in tapping their potential. However, there has been limited evidence about how and when their participation has beneficial impacts. We examine how peripheral developers contribute to product quality and diffusion by utilizing longitudinal data on 147 open-source software products. Hierarchical linear modeling analysis indicates that peripheral developers make significant contributions to product quality and diffusion, especially on projects that are in the more mature stages of product development.

These attributes make OSS an enticing technological choice for a company. Unfortunately, because most enterprises view technology as a proprietary differentiating element of their operation, little is known about the extent of OSS adoption in industry and the key drivers behind adoption decisions. In this article we examine factors and behaviors associated with the adoption of OSS and provide empirical findings through data gathered from the US Fortune-1000 companies. The data come from each company's web browsing and serving activities, gathered by sifting through more than 278 million web server log records and analyzing the results of thousands of network probes. We show that the adoption of OSS in large US companies is significant and is increasing over time through a low-churn transition, advancing from applications to platforms. Its adoption is a pragmatic decision influenced by network effects. It is likelier in larger organizations and those with many less productive employees, and is associated with IT and knowledge-intensive work and operating efficiencies.

Following a case study approach, the Apache Web server's market potential is estimated, forecasted and examined in terms of the socio-economic factors determining its diffusion, across different economic environments in developed versus developing countries. Market saturation is explored under the prism of three theoretical perspectives: the institutional, the endogenous and the exogenous growth theories. Findings suggest that Apache market saturation levels depend on both endogenous and exogenous to a country factors and that institutional quality plays an important role to the market potential. Implications for theory and public policy are discussed.

With dual licensing, a firm releases the same software product under both a traditional proprietary license and an open source one. We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of ""going open source"" and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

However, there have been conflicting reports on the extent to which this is true of the embedded software systems sector -- a large sector in Europe. This paper reports on attitudes towards Open Source software within that sector. Our results show a high level of acceptance of Open Source products with large, well established communities, and not only at the level of the operating system. Control over the software is seen as fundamentally important. Other key perceptions with Open Source are an easing of long-term maintenance problems and ready availability of support. The classical strengths of Open Source, namely mass inspection, ease of conducting trials, longevity and source code access for debugging, were at the forefront of thinking. However, there was an acknowledgement that more guidelines are needed for assessing Open Source software and incorporating it into products.

Drawing on research in information systems and sociology, this study develops and evaluates an integrated model for the acceptance of OSS. In addition to the traditional technology adoption variables the findings stress the importance of social identification as a key driver of OSS adoption. The proposed model provides a useful decision support tool for assessing and proactively designing interventions targeted at successful OSS adoption and diffusion.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

This paper seeks to identify how organizations adopt OSS, classify the literature according to these ways of adopting OSS, and with a focus on software development evaluate the research on adoption of OSS in organizations. Based on the systematic literature review method, the authors reviewed publications from 24 journals and seven conference and workshop proceedings, published between 1998 and 2008. From a population of 24,289 papers, the authors identified 112 papers that provide empirical evidence on how organizations actually adopt OSS. The authors show that adopting OSS involves more than simply using OSS products. The authors moreover provide a classification framework consisting of six distinctly different ways in which organizations adopt OSS. The authors find that existing research on OSS adoption does not sufficiently describe the context of the organizations studied, and it fails to benefit fully from related research fields.","2010-11","2025-04-25 15:25:24","2025-04-25 15:25:24","","1133","","11","52","","","","","","","","","","English","","","ABI/INFORM Global","751213257","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Adoption+of+open+source+software+in+software-intensive+organizations+-+A+systematic+literature+review&rft.au=Hauge%2C+%C3%98yvind%3BAyala%2C+Claudia%3BConradi%2C+Reidar.&rft.aulast=Hauge&rft.aufirst=%C3%98yvind&rft.date=2010-11-01&rft.volume=52&rft.issue=11&rft.spage=1133&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Open source; Open-source software; Technology adoption; Software development; Systematic review; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Computers--Data Base Management; Literature reviews","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

These organizations are voluntary in nature and rely on contributions from members to achieve their objectives. Examples include the Linux operating system and other FOSS projects, political movements, churches and religious groups, Habitat for Humanity, and similar charitable organizations. In this paper, we consider a world containing agents with heterogeneous abilities who may voluntarily choose to make effort contributions to one or more different public projects. Agents are motivated by a desire to be seen as significant contributors to important and valuable projects, the warm glow from the act of contributing, and a desire to directly enjoy the benefits of projects when complete. We find that contributions from others can be either strategic complements or substitutes. We show that Nash equilibria exist and study how agents' abilities and project quality affect the equilibrium levels of contributions.

These platforms are usually centered in a specific brand/product and their members are linked by a shared admiration to that brand. This paper analyzes one of the most powerful online collaborative platforms, the free software (FS) case, which involves a lot of virtual communities developed around products such as Linux or Android, the new Google's mobile operating system. Our purpose is to determine some of the main antecedents and consequences of the consumer involvement in this type of communities. Results have shown that satisfaction with a virtual community may increase the level of consumer participation in that community. At the same time, a greater identification with the virtual community may increase indirectly the consumer participation thanks to the enhancement of his/her satisfaction with the community. We have also found positive and significant effects of consumer identification and participation on the level of community promotion. Finally, positive and significant effects of consumer participation and satisfaction with the community on loyalty to the FS were also found. These findings allow us to conclude some interesting managerial implications.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-25 15:25:24","2025-04-25 15:25:24","","656","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","196420145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Using+the+DEMO+methodology+for+modeling+open+source+software+development+processes&rft.au=Huysmans%2C+Philip%3BVen%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Huysmans&rft.aufirst=Philip&rft.date=2010-06-01&rft.volume=52&rft.issue=6&rft.spage=656&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Computers--Data Base Management; Ontology; Demo; Process modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding the factors that affect the involvement and contributions of participants in OSS projects is of significance to facilitate project success. This paper investigates the effects of motivation on participant performance in OSS projects, drawing upon self-determination theory to examine how task effort (i. e., effort intensity and goal commitment) mediates the relationships between a spectrum of motivations and individual performance. The research model is supported by survey data from 204 participants in OSS projects. The theoretical contributions and managerial implications are discussed.

A recent literature has focused on the question of the business models explaining how and why firms may draw benefits from such involvement and their connected activities. They can be considered as the building blocks of a new modus operandi of an industry, built on an alternative approach to intellectual property management. Its prospects will depend on both the firms' willingness to rally and its ability to compete with the traditional proprietary approach. As a matter of fact, firms' involvement in FLOSS, while growing, remains very contrasted, depending on the nature of the products and the characteristics of the markets. This paper asks why for-profit firms contribute to FLOSS development and why some firms contribute more than others. The common explanation is that FLOSS is often a complement to proprietary software (or hardware or services) that the for-profit firm sells at a positive price. We present an alternative explanation based on the users' skill level. When users are skilled, opening the software is likely to result in a better product because the user base will contribute improvements (find bugs, write fixes and produce new features). We introduce the concept of the dominant user's skill and set up a theoretical model to better understand how it may condition the nature and outcome of the competition between a FLOSS firm and a proprietary firm. We discuss these results in the light of stylized facts drawn from recent trends in the software industry.

Nearly all open source software is free software; the two terms describe almost the same category of software. But they stand for views based on fundamentally different values. Open source is a development methodology; free software is a social movement. As the advocates of open source draw new users into the community, free software activists must work even more to bring the issue of freedom to those new users attention.","2009-06","2025-04-25 15:25:25","2025-04-25 15:25:25","","31","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","237063687","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Why+%26quot%3BOpen+Source%26quot%3B+Misses+the+Point+of+Free+Software&rft.au=Stallman%2C+Richard.&rft.aulast=Stallman&rft.aufirst=Richard&rft.date=2009-06-01&rft.volume=52&rft.issue=6&rft.spage=31&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/","Open source software; Community; Open source; Software; Free software; Freedom; 5240:Software & systems; Freeware; United States--US; 9190:United States; Open; Computers--Data Communications And Data Transmission Systems; Definitions; Differences","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.

Specifically, our research focused on learning effects of OSS projects and the factors that affect the learning process. The number and percentage of resolved bugs and bug resolution time of 118 SourceForge.net OSS projects were used to measure the learning effects. Projects were characterized by project type, number and experience of developers, number of bugs, and bug resolution time. Our results provided evidence of virtual organizational learning in OSS development projects and support for several factors as determinants of performance. Team size was a significant predictor, with mid-sized project teams functioning best. Teams of three to seven developers exhibited the highest efficiency over time and teams of eight to 15 produced the lowest mean time for bug resolution. Increasing the percentage of bugs assigned to specific developers or boosting developer participation in other OSS projects also improved performance. Furthermore, project type introduced variability in project team performance.

Respondents to an extensive web-survey's (FLOSS-US 2003) questions about their reasons for beginning to work FLOSS are classified according to their distinct ""motivational profiles"" by hierarchical cluster analysis. Over half of them also are matched to projects of known membership sizes, revealing that although some members from each of the clusters are present in the small, medium and large ranges of the distribution of project sizes, the mixing fractions for the large and the very small project ranges are statistically different. Among developers who changed projects, there is a discernable flow from the bottom toward the very small towards to large projects, some of which is motivated by individuals seeking to improve their programming skills. It is found that the profile of early motivation, along with other individual attributes, significantly affects individual developers' selections of projects from different regions of the size range.

These same institutions have also resulted in conflicts regarding community purposes and the quality and delivery of the community's output. We examine the institutional redesign undertaken to address these problems and derive implications for F/LOS communities and companies.

An important - but sometimes neglected - group of OSS users are Independent Software Vendors (ISVs). lSVs often develop their applications on top of OSS platform software. Frequently, this requires making several extensions and modifications to these OSS components. We identify a number of challenges that ISVs face in handling these extensions and modifications. Next, we describe several strategies ISVs can follow in maintaining these modifications. Finally, we suggest an opportunity for a closer collaboration between OSS projects and ISVs which could be mutually beneficial.

Following a case study methodology, we examined developer interaction data from three active and successful FLOSS projects using qualitative research methods, specifically inductive content analysis, to identify the task-assignment mechanisms used by the participants. We found that 'self-assignment' was the most common mechanism across three FLOSS projects. This mechanism is consistent with expectations for distributed and largely volunteer teams. We conclude by discussing whether these emergent practices can be usefully transferred to mainstream practice and indicating directions for future research.

We adapt a dynamic private-provision-of-public-goods model to reflect key aspects of the OSS phenomenon, such as play value or homo ludens payoff, user-programmers' and gift culture benefits.

This paper develops a framework of the OSS community ideology (including specific norms, beliefs, and values) and a theoretical model to show how adherence to components of the ideology impacts effectiveness in the OSS team. The model is based on the idea that the tenets of the OSS ideology motivate behaviors that enhance cognitive trust and communication quality and encourage identification with the project team, which enhances effective trust. Trust and communication in turn impact OSS team effectiveness. The research considers to kinds of effectiveness in OSS teams: the attraction and retention of developer input and the generation of project outputs. Hypotheses regarding antecedents to each are developed. Hypotheses are tested using survey and objective data on OSS projects. Results support the main thesis that OSS team ideology impacts OSS team effectiveness and reveal that different components impact effectiveness in different ways. Of particular interest is the finding that adherence to some ideological components was beneficial to the effectiveness of the team in terms of attracting and retaining input, but detrimental to the output of the team. Theoretical and practical implications are discussed.

Operations Support Systems (OSS) is one kind of EIS, which is becoming increasingly popular in the telecommunications industry. However, the academic research on knowledge management in OSS is sparse. In this paper, a knowledge management system for OSS is proposed in the framework of systems theory. Knowledge, knowledge management, organization and information technology are the four main interactive elements in the knowledge management system. The paper proposes that each subsystem of the OSS is to be equipped with knowledge management capacity, and the knowledge management of the OSS is to be realized through its subsystems.

Open source software (OSS) has challenged much of the traditional reasoning by suggesting that individuals behave altruistically and contribute to a public good, despite the opportunity to free-ride. The lion's share of the existing literature on OSS examines communities, that is, those individuals whom are already part of the OSS community. In contrast, this paper starts from users with the requisite skill to use and develop OSS. This group of skilled individuals could potentially invest into the development of OSS knowledge, but they may or may not do so in actuality. This paper, therefore, explores three issues, which have not been extensively explored in the literature, namely, (1) how frequently a group of skilled people use OSS, (2) reasons for differences among users and non-users in terms of use and attitudes, and (3) how frequently, and why, some users contribute to OSS projects (and thereby become developers). In doing so, we consider the opportunity costs of use and development of OSS, which has been largely neglected in the literature. We find that the individuals have a rather pragmatic attitude to firms and that many are active in both firms and OSS community, which raises many questions for future research about the role and influence of firms on the development and diffusion of OSS.

A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm-community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.

In the early parts of the paper it is argued that, although GNU/LINUX can generate substantial savings when used instead of the proprietary alternative in numerous institutional settings, the most telling opportunities for developing countries arise when this system is combined with other ways of reducing computing costs. Policy, therefore, should not only consist of substituting GNU/LINUX for proprietary software in running the latest and most expensive hardware, but also of lowering these latter costs themselves. Later sections focus on the link between the choice of software and path-dependency. It is suggested that the problem of proprietary lock-in in developing countries has been greatly accentuated by piracy of Microsoft operating systems and that the result is a stagnation of the technological capabilities in software that these countries need so badly.","2003","2025-04-25 15:25:26","2025-04-25 15:25:26","","25-33","","1","29","","","","","","","","","","English","","","ABI/INFORM Global","224652541","","","Place: Amsterdam Publisher: Bowker-Saur Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Information+Science&rft.atitle=Free+software+and+the+digital+divide%3A+Opportunities+and+constraints+for+developing+countries&rft.au=James%2C+Jeffrey.&rft.aulast=James&rft.aufirst=Jeffrey&rft.date=2003-01-01&rft.volume=29&rft.issue=1&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=Journal+of+Information+Science&rft.issn=01655515&rft_id=info:doi/10.1177%2F016555103762202041","Studies; Library And Information Sciences; Linux; Operating systems; Free software; 5240:Software & systems; Freeware; 9130:Experimental/theoretical; 9180:International; International; Cost control; Developing countries--LDCs; Developing country; Internet access; Digital divide; Digital; LDCs","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers’ early careers and hence shed light on future research in this direction.","2023","2025-04-25 15:26:03","2025-04-25 15:26:03","","529-548","","2","49","","","","","","","","","","English","","","ABI/INFORM Global","2776777604","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Off+to+a+Good+Start%3A+Dynamic+Contribution+Patterns+and+Technical+Success+in+an+OSS+Newcomer%26rsquo%3Bs+Early+Career&rft.au=Yang%2C+Yue%3BWang%2C+Yi%3BRedmiles%2C+David.&rft.aulast=Yang&rft.aufirst=Yue&rft.date=2023-01-01&rft.volume=49&rft.issue=2&rft.spage=529&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2022.3156071","Careers; open source; Task analysis; Ecosystems; Success; Documentation; Engineering profession; Codes; Correlation; Newcomer; Focusing; Statistical analysis; Computers--Software; Empirical analysis; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Several vulnerability scanners to detect known-vulnerable dependencies appeared in the last decade, however, there exists no case study investigating the impact of development practices, e.g., forking, patching, re-bundling, on their performance. This paper studies (i) types of modifications that may affect vulnerable open-source dependencies and (ii) their impact on the performance of vulnerability scanners. Through an empirical study on 7,024 Java projects developed at SAP , we identified four types of modifications: re-compilation, re-bundling, metadata-removal and re-packaging. In particular, we found that more than 87 percent (56 percent, resp.) of the vulnerable Java classes considered occur in Maven Central in re-bundled (re-packaged, resp.) form. We assessed the impact of these modifications on the performance of the open-source vulnerability scanners OWASP Dependency-Check (OWASP) and Eclipse Steady, GitHub Security Alerts, and three commercial scanners. The results show that none of the scanners is able to handle all the types of modifications identified.

Although the quality of developers’ contributions should be the only factor influencing the evaluation of the contributions to OSS projects, recent studies have shown that diversity issues are correlated with the acceptance or rejection of developers’ contributions. Objective: This paper assists this emerging state-of-the-art body on diversity research with the first empirical study that analyzes how developers’ perceptible race and ethnicity relates to the evaluation of the contributions in OSS. We also want to create awareness of the racial and ethnic diversity in OSS projects. Methodology: We performed a large-scale quantitative study of OSS projects in GitHub. We extracted the developers’ perceptible race and ethnicity from their names in GitHub using the Name-Prism tool and applied regression modeling of contributions (i.e, pull requests) data from GHTorrent and GitHub. Results: We observed that (1) among the developers whose perceptible race and ethnicity was captured by the tool, only 16.56 percent were perceptible as Non-White developers; (2) contributions from perceptible White developers have about 6–10 percent higher odds of being accepted when compared to contributions from perceptible Non-White developers; and (3) submitters with perceptible non-white races and ethnicities are more likely to get their pull requests accepted when the integrator is estimated to be from their same race and ethnicity rather than when the integrator is estimated to be White. Conclusion: Our initial analysis shows a low number of Non-White developers participating in OSS. Furthermore, the results from our regression analysis lead us to believe that there may exist differences between the evaluation of the contributions from different perceptible races and ethnicities. Thus, our findings reinforce the need for further studies on racial and ethnic diversity in software engineering to foster healthier OSS communities.","2022","2025-04-25 15:26:03","2025-04-25 15:26:03","","2955-2968","","8","48","","","","","","","","","","English","","","ABI/INFORM Global","2703102371","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=On+the+Relationship+Between+the+Developer%26rsquo%3Bs+Perceptible+Race+and+Ethnicity+and+the+Evaluation+of+Contributions+in+OSS&rft.au=Nadri%2C+Reza%3BRodriguez-Perez%2C+Gema%3BNagappan%2C+Meiyappan.&rft.aulast=Nadri&rft.aufirst=Reza&rft.date=2022-01-01&rft.volume=48&rft.issue=8&rft.spage=2955&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2021.3073773","Open source software; GitHub; Ethnicity; software development; open source software; Race; Software engineering; Open-source software; Tools; Psychology; Regression analysis; Multiculturalism; Gender issues; Software development management; Diversity; Cultural differences; Perceptible race and ethnicity diversity; Developer; Computers--Software; Empirical analysis; Ethnic group; Integrators; Multiculturalism & pluralism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Economics often pictures this phenomenon as a case of signalling: individuals engage in the volunteer programming of open-source software (OSS) as a labour-market signal resulting in a wage premium. Yet, this explanation could so far not be empirically tested. This article fills this gap by estimating an upper-bound composite wage premium of voluntary OSS contributions and by separating the potential signalling effect of OSS engagement from other effects. Although some 70% of OSS contributors believe that OSS involvement benefits their careers, we find no actual labour-market premium for OSS engagement. The presence of other motives, such as fun of play or altruism, renders OSS contributions too noisy to function as a signal.","2017-03","2025-04-25 15:26:03","2025-04-25 15:26:03","","1379-1394","","14","49","","","","","","","","","","English","","","ABI/INFORM Global","1881460983","","","Place: London Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Applied+Economics&rft.atitle=Is+there+a+wage+premium+for+volunteer+OSS+engagement%3F+-+signalling%2C+learning+and+noise&rft.au=Bitzer%2C+J%C3%BCrgen%3BGeishecker%2C+Ingo%3BSchr%C3%B6der%2C+Philipp+J.+H..&rft.aulast=Bitzer&rft.aufirst=J%C3%BCrgen&rft.date=2017-03-01&rft.volume=49&rft.issue=14&rft.spage=1379&rft.isbn=&rft.btitle=&rft.title=Applied+Economics&rft.issn=00036846&rft_id=info:doi/10.1080%2F00036846.2016.1218427","Open source software; peer production; Business And Economics; Open-source software; Noise; Engagement; open-source software; Public domain; Volunteering; D01; J24; J31; Signalling; voluntary work; wage formation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With it, they aim to empower and encourage development teams across organizations to perform small-scale, routine usability testing. A usability lab is, in essence, an observation platform for learning from the interaction between a participant and an application. Their experience shows that setting up an observation platform with enough quality for usability testing can be done with relative ease, without licensing fees or special platform requirements.

While the benefits resulting from network externality have been examined in the related literature, the effect of free offer on the diffusion of new software has not been formally analyzed. We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters. Our methodology is shown to be applicable for both fixed and dynamic pricing strategies.

Enormous research efforts have been devoted to understanding this phenomenon and trying to pursue a win-win result. To characterize the current research achievement and identify challenges, this article provides a comprehensive systematic literature review (SLR) of existing research on company participation in OSS. We collected 105 papers and organized them based on their research topics, which cover three main directions, i.e., participation motivation, contribution model, and impact on OSS development. We found that companies have diverse motivations from economic, technological, and social aspects, and no one study covered all the motivation categories. Existing studies categorize five main companies’ contribution models in OSS projects through their objectives and how they shape OSS communities. Researchers also explored how commercial participation affects OSS development, including companies, developers, and OSS projects. This study contributes to a comprehensive understanding of commercial participation in OSS development.

Our aim is to enable future research and tool development to increase efficiency and reduce the risks of copy-based reuse. We seek a better understanding of such reuse by measuring its prevalence and identifying factors affecting the propensity to reuse. To identify reused artifacts and trace their origins, our method exploits World of Code infrastructure. We begin with a set of theory-derived factors related to the propensity to reuse, sample instances of different reuse types, and survey developers to better understand their intentions. Our results indicate that copy-based reuse is common, with many developers being aware of it when writing code. The propensity for a file to be reused varies greatly among languages and between source code and binary files, consistently decreasing over time. Files introduced by popular projects are more likely to be reused, but at least half of reused resources originate from “small” and “medium” projects.

While far from an ideal approach, a common practice that OSS communities adopt to collaboratively address usability is through discussions on issue tracking systems (ITSs). However, there is little knowledge about the extent to which OSS community members engage in usability issue discussions, the aspects of usability they frequently target, and the characteristics of their collaboration around usability issue discussions. This knowledge is important for providing practical recommendations and research directions to better support OSS communities in addressing this important topic and improve OSS usability in general. To help achieve this goal, we performed an extensive empirical study on issues discussed in five popular OSS applications: three data science notebook projects (Jupyter Lab, Google Colab, and CoCalc) and two code editor projects (VSCode and Atom). Our results indicated that while usability issues are extensively discussed in the OSS projects, their scope tended to be limited to efficiency and aesthetics. Additionally, these issues are more frequently posted by experienced community members and display distinguishable characteristics, such as involving more visual communication and more participants. Our results provide important implications that can inform the OSS practitioners to better engage the community in usability issue discussion and shed light on future research efforts toward collaboration techniques and tools for discussing niche topics in diverse communities, such as the usability issues in the OSS context.","2024-04","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","CSCW1","8","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software; usability; issue tracking systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent work has pointed out two kinds of risks in these systems: that technical problems like bugs and vulnerabilities can spread through dependency links, and that relatively few developers are responsible for maintaining even the most widely used libraries. However, a more holistic diagnosis of systemic risk in software ecosystem should consider how these social and technical sources of risk interact and amplify one another. Motivated by the observation that the same individuals maintain several libraries within dependency networks, we present a methodological framework to measure risk in software ecosystems as a function of both dependencies and developers. In our models, a library’s chance of failure increases as its developers leave and as its upstream dependencies fail. We apply our method to data from the Rust ecosystem, highlighting several systemically important libraries that are overlooked when only considering technical dependencies. We compare potential interventions, seeking better ways to deploy limited developer resources with a view to improving overall ecosystem health and software supply chain resilience.","2024-02","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","1","3","","","","","","","","","","","","","","","","","Place: USA Publisher: Sage Publications, Inc.","","","","Open source software; networks; decentralized collaboration; social-technical systems; systemic risk","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers’ positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-05","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","4","32","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","hierarchy; developer networks; Open-source software projects; organizational structure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

But many OSS projects do not become sustainable, resulting in abandonment and even risks for the world's digital infrastructure. Prior work has looked at the reasons for this mainly from two very different perspectives. In software engineering, the focus has been on understanding success and sustainability from the socio-technical perspective: the OSS programmers' day-to-day activities and the artifacts they create. In institutional analysis, on the other hand, emphasis has been on institutional designs (e.g., policies, rules, and norms) that structure project governance. Even though each is necessary for a comprehensive understanding of OSS projects, the connection and interaction between the two approaches have been barely explored.In this paper, we make the first effort toward understanding OSS project sustainability using a dual-view analysis, by combining institutional analysis with socio-technical systems analysis. In particular, we (i) use linguistic approaches to extract institutional rules and norms from OSS contributors' communications to represent the evolution of their governance systems, and (ii) construct socio-technical networks based on longitudinal collaboration records to represent each project's organizational structure. We combined the two methods and applied them to a dataset of developer digital traces from 253 nascent OSS projects within the Apache Software Foundation (ASF) incubator. We find that the socio-technical and institutional features relate to each other, and provide complimentary views into the progress of the ASF's OSS projects. Refining these combined analyses can help provide a more precise understanding of the synchronization between the evolution of institutional governance and organizational structure.","2022-11","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","CSCW2","6","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","institutional design; OSS sustainability; socio-technical systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article systematically maps, aggregates, and synthesizes the state-of-the-art on women’s participation in OSS. It focuses on women contributors’ representation and demographics, how they contribute, their motivations and challenges, and strategies employed by communities to attract and retain women. We identified 51 articles (published between 2000 and 2021) that investigated women’s participation in OSS. We found evidence in these papers about who are the women who contribute, what motivates them to contribute, what types of contributions they make, challenges they face, and strategies proposed to support their participation. According to these studies, only about 5% of projects were reported to have women as core developers, and women authored less than 5% of pull-requests, but had similar or even higher rates of pull-request acceptances than men. Women make both code and non-code contributions, and their motivations to contribute include learning new skills, altruism, reciprocity, and kinship. Challenges that women face in OSS are mainly social, including lack of peer parity and non-inclusive communication from a toxic culture. We found 10 strategies reported in the literature, which we mapped to the reported challenges. Based on these results, we provide guidelines for future research and practice.","2022-08","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","4","31","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","bias; motivation; challenges; Gender; female","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study describes the conversations around adopting and crafting a code of conduct as well as those utilizing code of conduct for community governance. We conduct a qualitative analysis of a random sample of GitHub issues that involve the code of conduct. We find that codes of conduct are used both proactively and reactively to govern community behavior in project issues. Oftentimes, the initial addition of a code of conduct does not involve much community participation and input. However, a controversial moderation act is capable of inciting mass community feedback and backlash. Project maintainers balance the tension between disciplining potentially offensive forms of speech and encouraging broad and inclusive participation.

They are supported by peripheral developers, who contribute either via discussions or programming tasks, often for a limited time. It is unclear what role these peripheral developers play in the programming and communication efforts, as well as the temporary task-related sub-groups in the projects. We mine code-repository data and mailing-list discussions to model the relationships and contributions of developers in a social network and devise a method to analyze the temporal collaboration structures in communication and programming, learning about the strength and stability of social sub-groups in open-source software projects. Our method uses multi-modal social networks on a series of time windows. Previous work has reduced the network structure representing developer collaboration to networks with only one type of interaction, which impedes the simultaneous analysis of more than one type of interaction. We use both communication and version-control data of open-source software projects and model different types of interaction over time. To demonstrate the practicability of our measurement and analysis method, we investigate 10 substantial and popular open-source software projects and show that, if sub-groups evolve, modeling these sub-groups helps predict the future evolution of interaction levels of programmers and groups of developers. Our method allows maintainers and other stakeholders of open-source software projects to assess instabilities and organizational changes in developer interaction and can be applied to different use cases in organizational analysis, such as understanding the dynamics of a specific incident or discussion.","2021-11","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","2","31","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Coordination; open-source software; group structures; repository mining; tensor decomposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We particularly focus on how this labor of maintaining and sustaining changes as projects and their software grow and scale across many dimensions.

In this study, we explore an alternative way to organize a global software engineering course where students work on open source software development (OSSD) projects rather than in a multi-university collaboration setting. The results show that the new setup may provide core GSE challenges as well as challenges associated with software development outsourcing and challenges related to working on large open source software. The present article compares the experiences gained from running a combined GSE and OSSD course against the experiences gained from running a traditional GSE course. The two alternatives are compared in terms of students’ learning outcomes and course organization. The authors found that a combined GSE and OSSD course provides learning opportunities that are partly overlapping with, and partly complementary to, a traditional GSE course. The authors also found that the combined OSSD and GSE course was somewhat easier to organize because most of the activities took place in a single university setting. The authors used the extended GSE taxonomy for the comparison and found it to be a useful tool for this, although it had some limitations in expressive power. Therefore, two additional relationship dimensions are proposed that will further enrich the extended taxonomy in classifying GSE (and OSSD) projects.","2019-01","2025-04-25 15:26:48","2025-04-25 15:26:48","","","","2","19","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","OSS; Open Source Software Development; Global software engineering; GSE Education; GSE Taxonomy; Software Development Outsourcing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Organizations are also now adopting OSS, despite some reservations, particularly about the quality issues. Stability of software is one of the main features in software quality management that needs to be understood and accurately predicted. It deals with the impact resulting from software changes and argues that stable components lead to a cost-effective software evolution. Changes are most common phenomena present in OSS in comparison to proprietary software. This makes OSS system evolution a rich context to study and predict stability. Our objective in this work is to build stability prediction models that are not only accurate but also interpretable, that is, able to explain the link between the architectural aspects of a software component and its stability behavior in the context of OSS. Therefore, we propose a new approach based on classifiers combination capable of preserving prediction interpretability. Our approach is classifier-structure dependent. Therefore, we propose a particular solution for combining Bayesian classifiers in order to derive a more accurate composite classifier that preserves interpretability. This solution is implemented using a genetic algorithm and applied in the context of an OSS large-scale system, namely the standard Java API. The empirical results show that our approach outperforms state-of-the-art approaches from both machine learning and software engineering.","2014-04","2025-04-25 15:26:49","2025-04-25 15:26:49","","","","1","5","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Bayesian classifiers; genetic algorithm; Software stability prediction","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such systems save a great deal of effort over ad hoc ways of advertising, packaging, and transmitting useful libraries, but coordination among project teams is still needed when one package makes a breaking change affecting other packages. Ecosystems differ in their approaches to breaking changes, and there is no general theory to explain the relationships between features, behavioral norms, ecosystem outcomes, and motivating values. We address this through two empirical studies. In an interview case study, we contrast Eclipse, NPM, and CRAN, demonstrating that these different norms for coordination of breaking changes shift the costs of using and maintaining the software among stakeholders, appropriate to each ecosystem’s mission. In a second study, we combine a survey, repository mining, and document analysis to broaden and systematize these observations across 18 ecosystems. We find that all ecosystems share values such as stability and compatibility, but differ in other values. Ecosystems’ practices often support their espoused values, but in surprisingly diverse ways.

This is especially important for ""infrastructure"" projects, such as critical libraries and programming languages that many other people depend on. Some projects have taken the approach of borrowing planning tools that originated in commercial development, despite the fact that these techniques were designed for very different contexts, e.g. strong top-down control and profit motives. Little research has been done to understand how these practices are adapted to a new context. In this paper, we examine the Rust project's use of roadmaps: how has an important OSS infrastructure project adapted an inherently top-down tool to the freewheeling world of OSS? We find that because Rust's roadmaps are built in part by summarizing what motivated developers most prefer to work on, they are in some ways more a description of the motivated labor available than they are a directive that the community move in a particular direction. They allow the community to avoid wasting time on unpopular proposals by revealing that there will be little help in building them, and encouraging work on popular features by making visible the amount of consensus in those features. Roadmaps generate a collective focus without limiting the full scope of what developers work on: roadmap issues consume proportionally more effort than other issues, but constitute a minority of the work done (i.e issues and pull requests made) by both central and peripheral participants. They also create transparency among and beyond the community into what central contributors' plans are, and allow more rational decision-making by providing a way for evidence about community needs to be linked to decision-making.","2021-04","2025-04-25 15:26:49","2025-04-25 15:26:49","","","","CSCW1","5","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source; collaboration; common pool resources; rust language","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In addition to an appropriate software budget, activities such as installing security software, setting up user accounts, and configuring lab systems can require significant time and labor resources. In a conventional environment, it may also require a dedicated computer lab for each security class. In a given educational environment, obtaining these resources may be problematic.To mitigate these problems, we developed a ""hand on"" security design process that utilizes Live CDs and Open Source tools. By definition, a Live CD is a bootable CD that contains a complete operating system. Many Live CDs also include useful security utilities. In our security classes, we have utilized both general purpose Live CDs, such as Knoppix, and dedicated security centric Live CDs, such as Auditor.

However, in open-source software (OSS) development, stakeholders’ social interactions are often decentralized, iterative, and dynamic. Little is known about new requirements identification in OSS and the stakeholders’ organizational arrangements supporting such an activity. In this article, we investigate the theory of structural hole from the context of contributing new requirements in OSS projects. Structural hole theory suggests that stakeholders positioned in the structural holes in their social network are able to produce new ideas. In this study, we find that structural hole positions emerge in stakeholders’ social network and these positions are positively related to contributing a higher number of new requirements. We find that along with structural hole positions, stakeholders’ role is also an important part in identifying new requirements. We further observe that structural hole positions evolve over time, thereby identifying requirements to realize enriched features. Our work advances the fundamental understanding of the RE process in a decentralized environment and opens avenues for improved techniques supporting this process.","2015-09","2025-04-25 15:26:49","2025-04-25 15:26:49","","","","3","6","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","social capital; brokerage; open-source requirements engineering; Requirements identification; social information foraging theory; stakeholders’ social network; structural hole","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Further, we perform an initial deployment of FOSS by working with the Internet Service Provider (ISP) to detect distributed denial of service (DDoS) attacks.

Deep learning frameworks have been proposed to facilitate the development of such software systems, among which, PyTorch and TensorFlow stand out as notable examples. Considerable attention focuses on exploring software engineering practices and addressing diverse technical aspects in developing and deploying deep learning frameworks and software systems. Despite these efforts, little is known about the open source software communities involved in the development of deep learning frameworks.In this article, we perform a comparative investigation into the open source software communities of the two representative deep learning frameworks, PyTorch and TensorFlow. To facilitate the investigation, we compile a dataset of 2,792 and 3,288 code commit authors, along with 9,826 and 19,750 participants engaged in issue events on GitHub, from the two communities, respectively. With the dataset, we first characterize the structures of the two communities by employing four operationalizations to classify contributors into various roles and inspect the contributions made by common contributors across the two communities. We then conduct a longitudinal analysis to characterize the evolution of the two communities across various releases, in terms of the numbers of contributors with various roles and role transitions among contributors. Finally, we explore the causal effects between community characteristics and the popularity of the two frameworks.We find that the TensorFlow community harbors a larger base of contributors, encompassing a higher proportion of core developers and a more extensive cohort of active users compared to the PyTorch community. In terms of the technical background of the developers, 64.4% and 56.1% developers in the PyTorch and TensorFlow communities are employed by the leading companies of the corresponding open source software projects, Meta and Google, respectively; 25.9% and 21.9% core developers in the PyTorch and TensorFlow communities possess Ph.D. degrees, while 77.2% and 77.7% contribute to other machine learning or deep learning open source projects, respectively. Developers contributing to both communities demonstrate spatial and temporal similarities to some extent in their pull requests across the respective projects. The evolution of contributors with various roles exhibits a consistent upward trend over time in the PyTorch community. Conversely, a noticeable turning point in the growth of contributors characterizes the evolution of the TensorFlow community. Both communities show a statistically significant decreasing trend in the inflow rates of core developers. Furthermore, we observe statistically significant causal effects between the expansion of communities and retention of core developers and the popularity of deep learning frameworks. Based on our findings, we discuss implications, provide recommendations for sustaining open source software communities of deep learning frameworks, and outline directions for future research.","2025-02","2025-04-25 15:26:49","2025-04-25 15:26:49","","","","3","34","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","GitHub; community evolution; Deep learning; developer classification","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Comput.","","","10.1145/3290837","https://doi.org/10.1145/3290837","Participation by product users is critical to success in free, open-source software (FOSS) software communities as they originate and develop valuable ideas for product innovation that are unlikely to originate from the core software development community. Users tend to be involved at the periphery of FOSS communities, suggesting new product ideas, highlighting problems with user documentation, or explaining when the product design fails to fit with the needs of their local user application domain. As an increasing number of FOSS projects employ a hybrid participation model that combines volunteer effort with paid software development effort or product support, it can be difficult for non-developer users to participate in product innovation. In colocated organizations, it is theorized that peripheral participants learn how to engage with the practices and cultural identity of a community through a sociocultural apprenticeship known as legitimate peripheral participation. But we have little literature that explores how legitimate peripheral participation is enabled in online communities.The research study presented in this article explores how participation by peripheral users in a hybrid FOSS project is afforded by participation architecture channels and community mechanisms that mediate two forms of engagement: a “cognitive apprenticeship” that introduces participants to situated domain activity, such as the community processes involved in product innovation, and a “social apprenticeship” by which participants become enculturated in the system of meanings, values, norms, and behaviors that govern community/participant identity. We identified five stages of community innovation, analyzing sociotechnical affordances of the online participation architecture that enable peripheral participants to internalize the meanings of community practice and to develop a social identity within the FOSS community. Our contribution to theory is provided by the substantive explanation of the cognitive and social translations that enable legitimate peripheral participation in online communities, mediated by sociotechnical access channels and mechanisms that afford two contrasting forms of opportunities for action: those resulting from interactions between a goal-oriented actor and the technology platform features or channels of participation, and those associated with the social structures, roles, and relationships underpinning community interactions. Neither of these is sufficient without the other. Our contribution to practice is provided by an explanation of how four distinct categories of affordance provide these cognitive and social apprenticeship benefits, allowing participation architecture designers to cater to all forms of peripheral user participation. We conclude that the technical affordances of a typical FOSS community participation architecture are insufficient to mediate peripheral participation by nontechnical users. Meaningful participation is mediated by interactions between boundary spanners who play knowledge-brokering and organizational bridging roles. The combination of technical and social affordances enables peripheral participants to acquire an interior view of community practices and social culture and in turn to introduce new ideas, new values, and new rationales to produce a generative dance of innovation that percolates through the community.","2018-12","2025-04-25 15:26:50","2025-04-25 15:26:50","","","","4","1","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","innovation; affordances; hybrid-FOSS community; Legitimate peripheral participation; participation architecture; user participation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article, we describe five unique models from five distinct types of institutions for incorporating sustained FOSS or HFOSS (alternatively H/FOSS) project work into capstone experiences or courses. The goal is to provide instructors wishing to integrate open source experiences into their curriculum with additional perspectives and resources to help in adapting this approach to the specific needs and goals of their institution and students.

This article seeks to bridge this gap through an extensive survey that evaluates 127 technical studies published between 2014 and 2023, structured around the Vulnerability-Patch lifecycle. We begin by delineating the six critical events that constitute the Vulnerability-Patch lifecycle, leading to an in-depth exploration of the Vulnerability-Patch ecosystem. We then systematically review the databases commonly used in VD and SPD, and analyze their characteristics. Subsequently, we examine existing VD methods, focusing on traditional and deep learning based approaches. Additionally, we organize current security patch identification methods by kernel type and discuss techniques for detecting the presence of security patches.

We validated our findings through member checking with the interviewees as well as the ASF Diversity and Inclusion (D&I) committee. The contributions of this paper include: (1) an empirically-evidenced conceptual model of the 88 challenges that contributors face in a mature OSS foundation and (2) a set of 48 community-recommended strategies for alleviating these challenges.

However, the OSS landscape is slowly changing with more people and companies getting involved in OSS. This means that projects now need people in non-technical roles and activities to keep the project sustainable and evolving. In this paper, we focus on understanding the roles and activities that are part of the current OSS landscape and the different career pathways in OSS. By conducting and analyzing 17 interviews with OSS contributors who are well known in the community, we provide empirical evidence of the existence and importance of community-centric roles (e.g advocate, license manager, community founder) in addition to the well-known project-centric ones (e.g maintainer, core member). However, the community-centric roles typically remain hidden, since these roles may not leave traces in software repositories typically analyzed by researchers. We found that people can build a career in OSS through different roles and activities, with different backgrounds, including those not related to writing software. Furthermore, people's career pathways are fluid, moving between project and community-centric roles. Our work highlights that communities and researchers need to take action to acknowledge the importance of these varied roles, making these roles visible and well-recognized, which can ultimately help attract and retain more people in the OSS projects.","2020-10","2025-04-25 15:26:50","2025-04-25 15:26:50","","","","CSCW2","4","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open-source; collaborative development; career; role","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open- source software projects and provide clear implications for the structure of future open-source communities.","2016-04","2025-04-25 15:26:50","2025-04-25 15:26:50","","","","2","25","","","","","","","","","","","","","","","","","Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","natural experiment; commercial involvement; contributor inflow; contributor retention; extent and intensity of involvement; Hybrid project","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By identifying problems before they arise in production, it enhances the quality of the code. Finding the best reviewer for a code change, however, is extremely challenging especially in large scale, especially open source software stacks with cross functioning designs and collaborations among multiple developers and teams. Additionally, a review by someone who lacks knowledge and understanding of the code can result in high resource consumption and technical errors. The reviewers who have the specialty in both functioning (domain knowledge) and non-functioning areas of a commit are considered as the most qualified reviewer to look over any changes to the code. Quality attributes serve as the connection among the user requirements, delivered function description, software architecture and implementation through put the entire software stack cycle. In this study, we target on auto reviewer assignment in large scale software stacks and aim to build a self-learning, and self-correct platform for intelligently matching between a commit based on its quality attributes and the skills sets of reviewers. To achieve this, quality attributes are classified and abstracted from the commit messages and based on which, the commits are assigned to the reviewers with the capability in reviewing the target commits. We first designed machine learning schemes for abstracting quality attributes based on historical data from the OpenStack repository. Two models are built and trained for automating the classification of the commits based on their quality attributes using the manual labeling of commits and multi-class classifiers. We then positioned the reviewers based on their historical data and the quality attributes characteristics. Finally we selected the recommended reviewer based on the distance between a commit and candidate reviewers. In this paper, we demonstrate how the models can choose the best quality attributes and assign the code review to the most qualified reviewers. With a comparatively small training dataset, the models are able to achieve F-1 scores of 77% and 85.31%, respectively.","2023","2025-04-25 15:27:15","2025-04-25 15:27:15","","","","","","","","","ASE '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Rochester, MI, USA","","","","Machine Learning; Code Review; Commit Classification; Large-scale; MPNet; Open-source","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Typically, the vulnerability report contains affected versions of a software. However, despite the validation by security expert who discovers and vendors who review, the affected versions are not always accurate. Especially, the complexity of maintaining its accuracy increases significantly when dealing with multiple versions and their differences. Several advances have been made to identify affected versions. However, they still face limitations. First, some existing approaches identify affected versions based on repository-hosting platforms (i.e., GitHub), but these versions are not always consistent with those in package registries (i.e., Maven). Second, existing approaches fail to distinguish the importance of different vulnerable methods and patched statements in face of vulnerabilities with multiple methods and change hunks.To address these problems, this paper proposes a novel approach, Vision, to accurately identify affected library versions (ALVs) for vulnerabilities. Vision uses library versions from the package registry as inputs. To distinguish the importance of vulnerable methods and patched statements, Vision performs critical method selection and critical statement selection to prioritize important changes and their context. Furthermore, the vulnerability signature is represented by weighted inter-procedural program dependency graphs that incorporate critical methods and statements. Vision determines ALVs based on the similarities between these weighted graphs. Our evaluation demonstrates that Vision outperforms state-of-the-art approaches, achieving a precision of 0.91 and a recall of 0.94. Additionally, our evaluation shows the practical usefulness of Vision in correcting affected versions in existing vulnerability databases.","2024","2025-04-25 15:27:15","2025-04-25 15:27:15","","1447–1459","","","","","","","ASE '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Sacramento, CA, USA","","","","open source software; vulnerability quality; affected versions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context.

In the context of collaborative software development, producing sound architectural documentation, where architectural views play a central role, is a crucial aspect for effective teamwork. Despite their importance, the use of architectural views in open-source projects to date remains only marginally explored.Goal: We aim at conducting a comprehensive analysis on an extensive corpus of open-source architectural views. The goal is to understand (i) what the “history” of architectural views is, (ii) how architectural views are represented, and (iii) what architectural views are used for in the context of open-source projects.Methods: We leverage a software repository mining process to systematically construct a dataset of 15k architectural views. Then, we perform (i) a quantitative analysis on the metadata of all 15k views and (ii) a qualitative analysis on a statistically-relevant sample of 373 views.Results: Most projects rely on a single architectural view, which is often used to document a medium or high level description of the architecture. Views are usually created at either the beginning or at the end of a project, are rarely updated, and tend to be maintained by a single contributor. Views usually adopt an informal colored notation without a supporting legend and frequently report technologies used. Deployment and control flow are the most recurrent viewpoints, and commonly cover concerns related to software maintainability and functional suitability.Conclusion: The state of the practice about architectural views in open-source software systems seems to favor informal descriptions. Despite this, the effort needed to create views might hinder keeping views up to date, and a common syntactic ground between viewpoints seems hard to find. To address current needs, we speculate that a solution could lie in defining and popularizing versionable, templateable views that can be integrated in collaborative programming environments.","2024","2025-04-25 15:27:15","2025-04-25 15:45:48","","396–415","","","","","","","","","","","Springer-Verlag","Berlin, Heidelberg","","","","","","","","event-place: Luxembourg City, Luxembourg","","","","Open Source Software; Architectural Documentation; Architectural Views; Repository Mining","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, a common issue arises when incorporating third-party OSS accompanied with licenses, i.e., license incompatibility, which occurs when multiple licenses exist in one project and there are conflicts between them. Despite being problematic, fixing license incompatibility issues requires substantial efforts due to the lack of license understanding and complex package dependency. In this paper, we propose LiResolver, a fine-grained, scalable, and flexible tool to resolve license incompatibility issues for open source software. Specifically, it first understands the semantics of licenses through fine-grained entity extraction and relation extraction. Then, it detects and resolves license incompatibility issues by recommending official licenses in priority. When no official licenses can satisfy the constraints, it generates a custom license as an alternative solution.

Existing static analysis methods struggle with high false positive rates and are easily thwarted by obfuscation and dynamic code execution techniques. While dynamic analysis approaches offer improvements, they often suffer from capturing non-package behaviors and employing simplistic testing strategies that fail to trigger sophisticated malicious behaviors. To address these challenges, we present OSCAR, a robust dynamic code poisoning detection pipeline for NPM and PyPI ecosystems. OSCAR fully executes packages in a sandbox environment, employs fuzz testing on exported functions and classes, and implements aspect-based behavior monitoring with tailored API hook points. We evaluate OSCAR against six existing tools using a comprehensive benchmark dataset of real-world malicious and benign packages. OSCAR achieves an F1 score of 0.95 in NPM and 0.91 in PyPI, confirming that OSCAR is as effective as the current state-of-the-art technologies. Furthermore, for benign packages exhibiting characteristics typical of malicious packages, OSCAR reduces the false positive rate by an average of 32.06% in NPM (from 34.63% to 2.57%) and 39.87% in PyPI (from 41.10% to 1.23%), compared to other tools, significantly reducing the workload of manual reviews in real-world deployments. In cooperation with Ant Group, a leading financial technology company, we have deployed OSCAR on its NPM and PyPI mirrors since January 2023, identifying 10,404 malicious NPM packages and 1,235 malicious PyPI packages over 18 months. This work not only bridges the gap between academic research and industrial application in code poisoning detection but also provides a robust and practical solution that has been thoroughly tested in a real-world industrial setting.","2024","2025-04-25 15:27:16","2025-04-25 15:27:16","","1990–2001","","","","","","","ASE '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Sacramento, CA, USA","","","","NPM; PyPI; malicious code poisoning; OSS supply chain","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We analyze 17531 PRs of 18 OSS projects on GitHub, extracting 26 root causes of control-flow anomalies and 19 root causes of semantic anomalies.

We further discover and analyze the patterns of normal PR processes. We find that PRs in the non-fork model (42%) are far more likely than the fork model (5%) to bypass the review process, indicating a higher potential risk. Besides, we analyzed nine poisoned projects whose PR practices were indeed worse.

Therefore, researchers and OSS projects have proposed strategies to label tasks (a.k.a. issues). Several approaches relying on machine learning techniques, historical information, and textual analysis have been submitted. However, the results vary, and these approaches are still far from mainstream adoption, possibly because of a lack of good predictors. Inspired by previous research, we advocate that the prediction models might benefit from leveraging social metrics.In this research, we investigate how to assist the new contributors in finding a task when onboarding a new project. To achieve our goal, we predict the skills needed to solve an open issue by labeling them with the categories of APIs declared in the source code (API-domain labels) that should be updated or implemented. Starting from a case study using one project and an empirical experiment, we found the API-domain labels were relevant to select an issue for a contribution. In the sequence, we investigated employing interviews and a survey of what strategies maintainers the strategies believe the communities have to adopt to assist the new contributors in finding a task. We also studied how maintainers think about new contributors' strategies to pick a task. We found maintainers, frequent contributors, and new contributors diverge about the importance of the communities and new contributors' strategies.The ongoing research works in three directions: 1) generalization of the approach, 2) Use of conversation data metrics for predictions, 3) Demonstration of the approach, and 4) Matching contributors and tasks skills.By addressing the lack of knowledge about the skills in tasks, we hope to assist new contributors in picking tasks with more confidence.","2023","2025-04-25 15:27:16","2025-04-25 15:27:16","","311–313","","","","","","","ICSE '23","","","","IEEE Press","","","","","","","","","Place: Melbourne, Victoria, Australia","","","","machine learning; social network analysis; skills; mining software repositories; open-source software; labelling; ontology matching","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Central to the automation of these systems is the early detection of named entities, a task that is foundational yet fraught with challenges due to the need for domain-specific expert annotations amid a backdrop of specialized terminologies, making the process both costly and complex. In response to this challenge, our paper presents an innovative named entity recognition (NER) framework () tailored for the open-source software domain. Our method stands out by employing a distantly supervised, two-step annotation process that cleverly exploits language heuristics, bespoke lookup tables, external knowledge bases, and an active learning model. This multifaceted strategy not only elevates model performance but also addresses the critical hurdles of high costs and the dearth of expert annotators. A notable achievement of our approach is its capability to enable pre-large language models (pre-LLMs) to significantly outperform specially designed generic/domain specific LLMs for NER tasks.

For the OSS projects to stay sustainable, i.e., viable and maintained over time without interruption or weakening, maintenance labor requires an underlying infrastructure to be supported and secured. Aims: Using the construct of human infrastructure, our study aims to investigate how maintenance labor can be supported and secured to enable the creation and maintenance of sustainable OSS projects, viewed from the maintainers’ perspective. Method: In our exploration, we interviewed ten maintainers from nine well-adopted OSS projects. We coded the data in two steps using investigator-triangulation. Results: We constructed a framework of infrastructure design that provide insight for OSS projects in the design of their human infrastructure. The framework specifically highlight the importance of human factors, e.g., securing a work-life balance and proactively managing social pressure, toxicity, and diversity. We also note both differences and overlaps in how the infrastructure needs to support and secure maintenance labor from maintainers and the wider OSS community, respectively. Funding is specifically highlighted as an important enabler for both types of resources. Conclusions: The study contributes to the qualitative understanding of the importance, sensitivity, and risk for depletion of the maintenance labor required to build and maintain healthy OSS projects. Human infrastructure is pivotal in ensuring that maintenance labor is sustainable, and by extension the OSS projects on which we all depend.","2024","2025-04-25 15:27:16","2025-04-25 15:27:16","","37–48","","","","","","","ESEM '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Barcelona, Spain","","","","Open Source Software; Human Factors; Sustainability; Community Health; Maintainers; Project Health","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These laws, such as the European Union’s General Data Protection Regulation (GDPR), require software developers to meet privacy-related requirements when interacting with users’ data. Prior research describes the impact of such laws on software development, but only for commercial software. Although open-source software is commonly integrated into regulated software, and thus must be engineered or adapted for compliance, we do not know how such laws impact open-source software development. Aims: To understand how data privacy laws affect open-source software (OSS) development, we focus on the European Union’s GDPR, as it is the most prominent such law. We investigated how GDPR compliance activities influence OSS developer activity (RQ1), how OSS developers perceive fulfilling GDPR requirements (RQ2), the most challenging GDPR requirements to implement (RQ3), and how OSS developers assess GDPR compliance (RQ4). Method: We distributed an online survey to explore perceptions of GDPR implementations from open-source developers (N=56). To augment this analysis, we further conducted a repository mining study to analyze development metrics on pull requests (N=31,462) submitted to open-source GitHub repositories. Results: Our results suggest GDPR policies complicate OSS development and introduce challenges, primarily regarding the management of users’ data, implementation costs and time, and assessments of compliance. Moreover, we observed negative perceptions of the GDPR from OSS developers and significant increases in development activity, in particular metrics related to coding and reviewing, on GitHub pull requests related to GDPR compliance. Conclusions: Our findings provide future research directions and implications for improving data privacy policies, motivating the need for relevant resources and automated tools to support data privacy regulation implementation and compliance efforts in OSS.","2024","2025-04-25 15:27:17","2025-04-25 15:27:17","","325–336","","","","","","","ESEM '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Barcelona, Spain","","","","Open-Source Software; Data Privacy; Regulatory Compliance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Consequently, software engineers are adopting pre-trained models (PTMs) for their downstream applications. The dynamics of the PTM supply chain remain largely unexplored, signaling a clear need for structured datasets that document not only the metadata but also the subsequent applications of these models. Without such data, the MSR community cannot comprehensively understand the impact of PTM adoption and reuse.This paper presents the PeaTMOSS dataset, which comprises metadata for 281,638 PTMs and detailed snapshots for all PTMs with over 50 monthly downloads (14,296 PTMs), along with 28,575 open-source software repositories from GitHub that utilize these models. Additionally, the dataset includes 44,337 mappings from 15,129 downstream GitHub repositories to the 2,530 PTMs they use. To enhance the dataset's comprehensiveness, we developed prompts for a large language model to automatically extract model metadata, including the model's training datasets, parameters, and evaluation metrics. Our analysis of this dataset provides the first summary statistics for the PTM supply chain, showing the trend of PTM development and common shortcomings of PTM package documentation. Our example application reveals inconsistencies in software licenses across PTMs and their dependent projects. PeaTMOSS lays the foundation for future research, offering rich opportunities to investigate the PTM supply chain.

To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., ""good first issues""), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.","2023","2025-04-25 15:27:17","2025-04-25 15:27:17","","324–336","","","","","","","ICSE-SEET '23","","","","IEEE Press","","","","","","","","","Place: Melbourne, Australia","","","","open source software; open source onboarding; software engineering education","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

FOSS is subject to various legal terms and restrictions, depending on the type of open source license in force. Hence it is important to remain compliant with the FOSS license terms. Identifying the licenses that provide FOSS and understanding the terms of those licenses is not easy, especially when dealing with a large amount of reuse that is common in modern software development. Since reused software is often large, automated license analysis is needed to address these issues and support users in license compliant reuse of FOSS. However, existing license assessment tools can only identify the name and quantity of licenses embedded in software and thus cannot identify whether the licenses are being used safely and correctly. Moreover, they cannot provide a comprehensive analysis of the compatibility and potential risk that come with the term conflicts.In this paper, we propose DIKE, an automated tool that can perform license detection and conflict analysis for FOSS. First, DIKE extracts 12 terms under 3,256 unique open source licenses by manual analysis and Natural Language Processing (NLP) and constructs a license knowledge base containing the responsibilities of the terms. Second, DIKE scans all licenses from the code snippet for the input software and outputs the scan results in a tree structure. Third, the scan results match the license knowledge base to detect license conflicts from terms and conditions. DIKE designs two solutions for software with license conflicts: license replacement and code replacement. To demonstrate the effectiveness of DIKE, we first evaluate with the term extraction and responsibility classification, and the results show that their F1-scores reach 0.816 and 0.948, respectively. In addition, we conduct a measurement study of 16,341 popular projects from GitHub based on our proposed DIKE to explore the conflict of license usage in FOSS. The results show that 1,787 open source licenses are used in the project, and 27.2% of licenses conflict. Our new findings suggest that conflicts are prevalent in FOSS, warning the open source community about intellectual property risks.","2023","2025-04-25 15:27:17","2025-04-25 15:43:22","","495–505","","","","","","","ICSE-SEIP '23","","","","IEEE Press","","","","","","","","","Place: Melbourne, Australia","","","","free and open source software; natural language processing; license analysis; license conflict","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A fork is a copy of the original repository that can evolve independently from the parent repository, allowing developers to experiment with a code base or test new features without the danger of affecting the original project. A fork can result in changes that are pushed back to the original project or even evolve into an independent project. Some projects tend to be forked extensively to the point where their forks are also forked and form families of projects. In this work, we explore the motivation, the practices and the culture of forking open-source software repositories.

Many previous works are developer-centric and overlook the importance of end-user forums. As a result, end-users' expectations are seldom reflected in OSS development. To better understand user behaviors in OSS user forums, we carried out an empirical study analyzing about 1.3 million posts from user forums of four popular OSS applications: Zotero, Audacity, VLC, and RStudio. Through analyzing the contribution patterns of three common user types (end-users, developers, and organizers), we observed that end-users not only initiated most of the threads (above 96% of threads in three projects, 86% in the other), but also acted as the significant contributors for responding to other users' posts, even though they tended to lack confidence in their activities as indicated by psycho-linguistic analyses. Moreover, we found end-users more open, reflecting a more positive emotion in communication than organizers and developers in the forums. Our work contributes new knowledge about end-users' activities and behaviors in OSS user forums that the vital OSS stakeholders can leverage to improve end-user engagement in the OSS development process.","2022","2025-04-25 15:27:17","2025-04-25 15:27:17","","46–55","","","","","","","CHASE '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Pittsburgh, Pennsylvania","","","","open-source software; linguistic analysis; user forums","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Inspirational communication therefore appears as central to the process of leader emergence in virtual teams, even in a setting like OSS, where technical contributions have often been conceptualized as the sole pathway to gaining community recognition.

While a number of studies proposed novel methods of representing expertise within individual projects, these methods are difficult to apply at an ecosystem level. However, with the focus of software development shifting from monolithic to modular, a method of representing developers' expertise in the context of the entire OSS development becomes necessary when, for example, a project tries to find new maintainers and look for developers with relevant skills. Aim: We aim to address this knowledge gap by proposing and constructing the Skill Space where each API, developer, and project is represented and postulate how the topology of this space should reflect what developers know (and projects need). Method: we use the World of Code infrastructure to extract the complete set of APIs in the files changed by open source developers and, based on that data, employ Doc2Vec embeddings for vector representations of APIs, developers, and projects. We then evaluate if these embeddings reflect the postulated topology of the Skill Space by predicting what new APIs/projects developers use/join, and whether or not their pull requests get accepted. We also check how the developers' representations in the Skill Space align with their self-reported API expertise. Result: Our results suggest that the proposed embeddings in the Skill Space appear to satisfy the postulated topology and we hope that such representations may aid in the construction of signals that increase trust (and efficiency) of open source ecosystems at large and may aid investigations of other phenomena related to developer proficiency and learning.","2021","2025-04-25 15:27:17","2025-04-25 15:27:17","","995–1007","","","","","","","ICSE '21","","","","IEEE Press","","","","","","","","","Place: Madrid, Spain","","","","Open Source; Machine Learning; API; World of Code; API embedding; Developer embedding; Developer Expertise; Doc2Vec; Expertise; Project embedding; Skill Space; Vector Embedding","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.","2023","2025-04-25 15:27:18","2025-04-25 15:27:18","","180–190","","","","","","","dg.o '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Gda?sk, Poland","","","","GitHub; open source software; government; barriers; benefits; citizen engagement; evidence","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In many Open Source Software Development (OSSD) communities, DM processes lie buried amongst vast amounts of publicly available data. Hidden within this data lie the rationale for decisions that led to the evolution and maintenance of software products. While there have been some efforts to extract DM processes from publicly available data, the rationale behind 'how' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million emails. This paper makes two main contributions. First, it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second, it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven, bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement). Our approach can be applied to extract rationale in other OSSD communities that have similar governance structures.","2021","2025-04-25 15:27:18","2025-04-25 15:27:18","","1008–1019","","","","","","","ICSE '21","","","","IEEE Press","","","","","","","","","Place: Madrid, Spain","","","","decision-making; Python; causal extraction; heuristics; Open Source Software Development (OSSD); rationale; Rationale Miner","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In a similar way, community smells consider the sub-optimal patterns in the organizational and social structures of software teams. Related work performed empirical studies to identify the relationship between community smells and software smells at the architecture and code levels. However, how community smells relate with design smells is still unknown. Aims: In this paper, we empirically investigate the relationship between community smells and design smells during the evolution of software projects. Method: We apply three statistical methods: correlation, trend, and information gain analysis to empirically examine the relationship between community and design smells in 100 releases of 10 large-scale Apache open-source software projects. Results: Our results reveal that the relationship between community and design smells varies across the analyzed projects. We find significant correlations and trend similarities for one type of community smell (when developers work in isolation without peer communication—Missing Links) with design smells in most of the analyzed projects. Furthermore, the results of our statistical model disclose that community smells are more relevant for design smells compared to other community-related factors. Conclusion: Our results find that the relationship of community smells (in particular, the Missing Links smell) exists with design smells. Based on our findings, we discuss specific community smell refactoring techniques that should be done together when refactoring design smells so that the problems associated with the social and technical (design) aspects of the projects can be managed concurrently.","2022","2025-04-25 15:27:18","2025-04-25 15:44:58","","23–33","","","","","","","ESEM '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Helsinki, Finland","","","","Community Smells; Design Smells; Open-Source Development.; Social Smells; Socio-Technical Analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Existing software tools enable characterizing and measuring the amount of technical debt at selective granularity levels; by providing a computational model, they enable stakeholders to measure and ultimately control this phenomenon. Aims: In this paper we aim to study the evolution and characteristics of technical debt in open-source software. For this, we carry out a longitudinal study that covers the entire development history of several complex applications. The goal is to improve our understanding of how the amount and composition of technical debt changes in evolving software. We also study how new technical debt is introduced in software, as well as identify how developers handle its accumulation over the long term. Method: We carried out our evaluation using three complex, open-source Java applications. All 110 released versions, covering more than 10 years of development history for each application were analyzed using SonarQube. We studied how the amount, composition and history of technical debt changed during development, compared our results across the studied applications and present our most important findings. Results: For each application, we identified key versions during which large amounts of technical debt were added, removed or both. This had significantly more impact when compared to the lines of code or class count increases that generally occurred during development. However, within each version, we found high correlation between file lines of code and technical debt. We observed that the Pareto principle was satisfied for the studied applications, as 20% of issue types generated around 80% of total technical debt. Interestingly, there was a large degree of overlap between the issues that generated most of the debt across the studied applications. Conclusions: Early application versions showed greater fluctuation in the amount of existing technical debt. We found application size to be an unreliable predictor for the quantity of technical debt. Most debt was introduced in applications as part of milestone releases that expanded their feature set; likewise, we identified releases where extensive refactoring significantly reduced the level of debt. We also discovered that technical debt issues persist for a long time in source code, and their removal did not appear to be prioritized according to type or severity.","2020","2025-04-25 15:27:18","2025-04-25 15:27:18","","","","","","","","","ESEM '20","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Bari, Italy","","","","software evolution; open-source; software maintenance; static analysis; technical debt","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components.

This decision is partly justified due to the difficulty of bringing to the context of a classroom a real software project. The widespread presence of open source projects, however, is contributing to alleviating this problem. Several instructors have already adopted contributions to open source projects as part of their evaluation process, and these instructors reported many benefits, including the improvement on students' technical and social skills. However, little is known about the students' perceptions regarding the need to contribute to an open source project as part of a Software Engineering course. To better understand the students' challenges, benefits, and attitudes, we conducted 21 semi-structured interviews with students who took these courses in five different Brazilian universities. We also enriched this data with an analysis of commits performed in the repositories that students contributed to. We observed that even though some instructors chose the open source projects to students to work themselves, some students and even the open source community participated in the process of choosing projects and tasks.

However, the adoption of these projects in the classroom presents some obstacles, such as choosing the appropriate project, and the time and effort needed to prepare the classes and get used to the open source environment. In order to reduce the difficulties faced by instructors, we are working on developing a portal to catalog worked examples extracted from OSS projects to assist instructors. In this paper, we present the first steps towards creating this catalog, which is creating a pattern for guiding the structuring the worked examples. We are applying the Design Science Research paradigm. The activities reported in this paper regards the first Design Cycle, and were divided into three stages related to the elaboration and evaluation of the pattern for cataloging the worked examples. In these stages, we carried out focus groups and interviews with Software Engineering instructors, including the instantiation of the pattern to catalog actual worked examples. After each stage, we had a new and improved version of the pattern for cataloging the worked examples. Such pattern served as a basis to create the first version of the worked examples portal, which will be evaluated in the next stages of the research.","2020","2025-04-25 15:27:18","2025-04-25 15:27:18","","493–498","","","","","","","SBES '20","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Natal, Brazil","","","","Open Source Software; Software Engineering Education; Worked Examples","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors’ learning processes is an important research area in OSS.This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education. It is argued that collaboration with peers and consistent code contributions result in learning progress in OSS.

This work proposes to close this gap by measuring dependency, code reuse, and knowledge flow networks in open source software. We have done preliminary work by developing suitable tools and methods that rely on public version control data to measure and comparing these networks for R language and emberjs packages. We propose ways to calculate the three networks for the entirety of public software, evaluate their accuracy, and to provide public infrastructure to build risk assessment and mitigation tools for various individual and organizational participants in open sources software.

In this context, influencers are those who guide the development methods and disseminate patterns due to their popularity or status in the community. Especially in software ecosystems, the dynamics of interactions with interventions of external developers over a common technological platform leverage the effects of influence and still remains as a challenge. This paper presents an exploratory study on the sense of influence in open source software ecosystems, more specifically from the opinions of 95 developers who contribute to npm projects based on GitHub. To do so, qualitative data from a conducted survey research were analyzed based on Grounded Theory (GT) procedures. Based on two main categories (Technical and Social), we recognized aspects that reinforce some key characteristics of an influencer, e.g., 'status in the project', 'participation with code', 'participation with comments ', and 'content value'. However, some diverging aspects were observed, e.g., the difference between qualitative and quantitative responses related to 'long-time interaction with the project'. This study contributes with the identification of influencers' characteristics that can aid both researchers in further studies on open source software ecosystems and practitioners in strategies to manage project-based ecosystems.","2020","2025-04-25 15:27:19","2025-04-25 15:43:48","","137–146","","","","","","","SBES '20","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Natal, Brazil","","","","GitHub; Open Source; Influence; Software Ecosystems; npm; Social Developer","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project’s capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of sub-topics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project’s overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.","2022","2025-04-25 15:27:19","2025-04-25 15:27:19","","","","","","","","","OpenSym '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Madrid, Spain","","","","Health; Open Source Software; Sustainability; Software Ecosystem; Software Quality.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We argue that these aspects are important, however, technical security practice considering different social aspects of OSS development will assure the effectiveness and efficiency of the implementation of the tool. To mitigate this research gap, in this empirical study, we explore the current security culture in the OSS development phenomenon using a survey instrument with six evaluation dimensions: attitude, behavior, competency, subjective norms, governance, and communication. By exploring the current security culture in OSS communities, we can start to understand the influence of security on participants' security behaviors and decision-making, so that we can make realistic and practical suggestions.

This paper attempts to investigate whether the Open Source Software research produces results considered relevant to undergraduate students. This way we can provide feedback from the students, offering a way to produce useful and, consequently, more disseminated works among Open Source practitioners. To answer about the relevance of available work, we have tackled two questions: one about the scope of the studies and another about the quality perceived by them.

The scientific literature presents several techniques that can be used to recognize the user's emotional state. However, many techniques involve the use of sensors that can result in financial costs and cause discomfort to the user. In this scenario, the recognition of the emotional state through the analysis of facial expressions presents itself as a useful and practical approach, since it does not involve the use of sensors attached to the user's body and executed in different types of devices. Despite these advantages, software that allow the analysis of facial expressions for free are still incipient, and performance evaluation of this type of software usually is not available. In order to contribute to this context and assist researchers who need this type of software, this study presents a comparative analysis of two open-source emotion recognition software (""CLMTrackr"" and ""Face-api.js"") simulating different environmental conditions related to lighting and distance. Considering images from two datasets, we generate 8675 videos simulating 25 different environmental conditions.

The data were obtained both from the National Vulnerability Database (NVD), and from project-specific web resources, which we monitor on a continuous basis.From that data, we extracted a dataset that maps 624 publicly disclosed vulnerabilities affecting 205 distinct open-source Java projects, used in SAP products or internal tools, onto the 1282 commits that fix them.

Moreover, these scripts allow to complement the dataset with additional instances that are not security fixes (which is useful, for example, in machine learning applications).Our dataset has been successfully used to train classifiers that could automatically identify security-relevant commits in code repositories.

The analysis of open source community dynamics is a key capability in risk management practices focused on the integration of FLOSS in all types of organizations. We are conducting research in developing methodologies for managing risks of FLOSS adoption and deployment in various application domains. This paper is about the ability to systematically capture, filter, analyze, reason about, and build theories upon, the behavior of an open source community in combination with the structured elicitation of expert opinions on potential organizational business risk. The novel methodology presented here blends together qualitative and quantitative information as part of a wider analytics platform. The approach combines big data analytics with automatic scripting of scenarios that permits experts to assess risk indicators and business risks in focused tactical and strategic workshops. These workshops generate data that is used to construct Bayesian networks that map data from community risk drivers into statistical distributions that are feeding the platform risk management dashboard. A special feature of this model is that the dynamics of an open source community are tracked using social network metrics that capture the structure of unstructured chat data. The method is illustrated with a running example based on experience gained in implementing our approach in an academic smart environment setting including Mood bile, a Mobile Learning for Moodle (www.moodbile.org).

This is at odds with current practice of performance testing, which predominantely focuses on long-running tests against entire systems in production-like environments. Alternatively, software microbenchmarking attempts to establish a performance baseline for small code fragments in short time. This paper investigates the quality of microbenchmark suites with a focus on suitability to deliver quick performance feedback and CI integration. We study ten open-source libraries written in Java and Go with benchmark suite sizes ranging from 16 to 983 tests, and runtimes between 11 minutes and 8.75 hours. We show that our study subjects include benchmarks with result variability of 50% or higher, indicating that not all benchmarks are useful for reliable discovery of slowdowns. We further artificially inject actual slowdowns into public API methods of the study subjects and test whether test suites are able to discover them. We introduce a performance-test quality metric called the API benchmarking score (ABS). ABS represents a benchmark suite's ability to find slowdowns among a set of defined core API methods. Resulting benchmarking scores (i.e., fraction of discovered slowdowns) vary between 10% and 100% for the study subjects. This paper's methodology and results can be used to (1) assess the quality of existing microbenchmark suites, (2) select a set of tests to be run as part of CI, and (3) suggest or generate benchmarks for currently untested parts of an API.","2018","2025-04-25 15:27:20","2025-04-25 15:43:38","","119–130","","","","","","","MSR '18","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Gothenburg, Sweden","","","","empirical study; Java; continuous integration; Go; microbenchmarking; software performance testing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of Business Intelligence (BI) tools can contribute to the improvement of the organizational processes of these organizations. However, the high financial cost, in many cases, makes it impossible for public institutions to acquire proprietary BI solutions. An alternative is the use of solutions based on free and/or open source software. To identify, among the available OSS-based BI tools, which is the most appropriate for implementation in public bodies, it is necessary to apply some specific model for evaluation and selection. The literature describes several generic methods for assessing and comparing OSS. In this work, we select a suitable method and derive a model for the comparison and selection of OSS-based BI tools able to meet the demands of public organizations. In addition, through a case study, we demonstrate how this model can be used in the selection of a tool that can contribute to the improvement of information management in an organizational environment.","2018","2025-04-25 15:27:20","2025-04-25 15:45:25","","","","","","","","","SBSI '18","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Caxias do Sul, Brazil","","","","Open Source Software; Business intelligence; Software evaluation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The TOE (Technology, Organization and Environment) framework has been used to study the influence of technological, organizational, and environmental factors considered by companies when adopting OSS. In this work, we collected data through online surveys answered by workers in IT companies in the state of Minas Gerais, Brazil. The proposed model for determining the impact of each factor on the adoption of OSS and on the business model practiced by IT companies was evaluated by using structural equations. The results show that three groups of factors impact the way of OSS adoption. Organizational and technological factors are the most relevant, whereas for business models only environmental factors are relevant. The most relevant technological factor identified is ""reduced hardware and software costs""; the most relevant organizational factor is ""flexibility of IT structure""; and the most relevant environmental factor is ""reports of successful use of OSS"". We verified that IT companies in Minas Gerais use OSS in software development, either by incorporating OSS components into their software products or by employing OSS tools for software development.","2015","2025-04-25 15:27:20","2025-04-25 15:27:20","","371–378","","","","","","","SBSI '15","","","","Brazilian Computer Society","Porto Alegre, BRA","","","","","","","","event-place: Goiania, Goias, Brazil","","","","Open source software; Technology adoption; IT companies; TOE framework","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this context there are two main issues: on the one hand, software creation practices, based on collaboration and sharing, on the other hand, the respective end-user programming tools for artists, hobbyists or children. This tutorial presents a coherent overview of related work and our own experiences in the organization and running of maker workshops. It encompasses creative sessions whose final goal is to inspire the participants to experience open software practices and tools. This goal can divided into three sub-goals: 1) Technical (Interactivity, multimedia) 2) Artistic (poetic message, playful, experimental) 3) Open (sharing, reuse and participation). As a side effect of the study, the participants will cooperate and get to know each other and learn examples of new media prototyping tools and sharing platforms.

This large amount of data hampers people to make sense of implicit links between software projects, e.g., Dependencies, patterns, licenses. This context raises the question of what techniques and mechanisms can be used to help users and developers to link related pieces of information across software projects. In this paper, we propose a framework for a marketplace enhanced using linked open data (LOD) technology for linking software artifacts within projects as well as across software projects. The marketplace provides the infrastructure for collecting and aggregating software engineering data as well as developing services for mining, statistics, analytics and visualization of software data. Based on cross linking software artifacts and projects, the marketplace enables developers and users to understand the individual value of components and their relationship to bigger software systems. Improved understanding creates new business opportunities for software companies: users will be able to analyze and compare projects, developers can increase the visibility of their products, and hosts may offer plugins and services over the data to paying customers.","2015","2025-04-25 15:27:21","2025-04-25 15:27:21","","3651–3660","","","","","","","HICSS '15","","","","IEEE Computer Society","USA","","","","","","","","","","","","open source software; linked data; semantic web","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore we explore reasons for systematic variance in these processes so as to enable more effective OSS development practices. Drawing on theory of distributed cognition, we develop a language of cognitive translations, which occur within and across distributed social arrangements and structural conditions of sharing knowledge. This language provides micro-foundations for understanding how different modes of OSS development emerge. Through examining how generative characteristics of social and structural distributions in OSS shape distinct development pathways, we propose a theoretically derived typology explaining the characteristics, dynamics, and conditions for success of different modes of OSS development.","2014","2025-04-25 15:27:21","2025-04-25 15:27:21","","4568–4577","","","","","","","HICSS '14","","","","IEEE Computer Society","USA","","","","","","","","","","","","Open Source Software; Emergence; Modes; Typology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSS coach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process.

To teach SE with OSS, however, it is necessary to select uniform projects of appropriate size and complexity. This paper reports on our search for suitable OSS projects to teach an introductory SE course with a focus on maintenance and evolution. The search turned out to be quite labor intensive and cumbersome, contrary to our expectations that it would be quick and simple.

Architectural decay is caused by repeated changes to a system during its lifespan. Despite decay's prevalence, there is a relative dearth of empirical data regarding the nature of architectural changes that may lead to decay, and of developers' understanding of those changes. In this paper, we take a step toward addressing that scarcity by conducting an empirical study of changes found in software architectures spanning several hundred versions of 14 open-source systems. Our study reveals several new findings regarding the frequency of architectural changes in software systems, the common points of departure in a system's architecture during maintenance and evolution, the difference between system-level and component-level architectural change, and the suitability of a system's implementation-level structure as a proxy for its architecture.","2015","2025-04-25 15:27:22","2025-04-25 15:43:15","","235–245","","","","","","","MSR '15","","","","IEEE Press","","","","","","","","","Place: Florence, Italy","","","","software evolution; architectural change; architecture recovery; open-source systems; software architecture","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer.

Software measurement is a particularly important procedure, as it provides meaningful information about the software artifact. This procedure is even more emerging when we refer to open source software, where the need for shared knowledge is crucial for the maintenance and evolution of the code. A paradigm of open source project where code quality is especially important is the scientific language R. This paper aims to perform measurements on the R statistical open source software, examine the relationships among the observed metrics and special attributes of the R software and search for certain characteristics that define its behavior and structure. For this purpose, a random sample of 508 R packages has been downloaded from the CRAN repository of R and has been measured, using the SourceMonitor metrics tool. The resulted measurements, along with a significant number of specific attributes of the R packages, were examined and analyzed, leading to interesting conclusions such as the validity of a power law distribution regarding the majority of the sample's metrics and the absence of specific patterns due to the interdependencies among packages. Finally, the effects of the number of developers and the number of dependencies are investigated, in order to understand their impact on the metrics of the sample packages.","2012","2025-04-25 15:27:22","2025-04-25 15:45:15","","1–10","","","","","","","SEW '12","","","","IEEE Computer Society","USA","","","","","","","","","","","","software metrics; complexity analysis; Open Source software measurement; R project","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Apparently, this is also true for open-sourced software – most users would not compile the available source, and implicitly trust that the available binaries have been compiled from the published source code (i.e., no backdoor has been inserted in the binary). To verify that the official binaries indeed correspond to the released source, one can compile the source of a given application, and then compare the locally generated binaries with the developer-provided official ones. However, such simple verification is non-trivial to achieve in practice, as modern compilers, and more generally, toolchains used in software packaging, have not been designed with verifiability in mind. Rather, the output of compilers is often dependent on parameters that can be strongly tied to the building environment. In this paper, we analyze a widely-used encryption tool, TrueCrypt, to verify its official binary with the corresponding source. We first manually replicate a close match to the official binaries of sixteen most recent versions of TrueCrypt for Windows up to v7.1a, and then explain the remaining differences that can solely be attributed to non-determinism in the build process. Our analysis provides the missing guarantee on official binaries that they are indeed backdoor-free, and makes audits on TrueCrypt's source code more meaningful. Also, we uncover several sources of non-determinism in TrueCrypt's compilation process; these findings may help create future verifiable build processes.","2014","2025-04-25 15:27:22","2025-04-25 15:27:22","","16–25","","","","","","","ACSAC '14","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: New Orleans, Louisiana, USA","","","","tor; debian; bitcoin; deterministic build; reproducible build; TrueCrypt","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We present four metrics as a starting point–size, centralization, density and clusterness, that are most useful in revealing collaborative relationships in OSS development process.

To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community.

We perform an in-depth analysis of build failures in CI environments. Our approach links repository commits to data of corresponding CI builds. Using data from 14 open-source Java projects, we first identify 14 common error categories. Besides test failures, which are by far the most common error category (up to >80% per project), we also identify noisy build data, e.g., induced by transient Git interaction errors, or general infrastructure flakiness. Second, we analyze which factors impact the build results, taking into account general process and specific CI metrics. Our results indicate that process metrics have a significant impact on the build outcome in 8 of the 14 projects on average, but the strongest influencing factor across all projects is overall stability in the recent build history. For 10 projects, more than 50% (up to 80%) of all failed builds follow a previous build failure.

Designing maintenance-centric SE projects, however, is difficult because software code upon which these projects must be based is not readily available. Open Source Software (OSS) can alleviate this issue by offering a rich and varied volume of code. This rich diversity of OSS projects, however, presents the greatest hurdle in seamlessly selecting suitable projects for integration. To better understand the scope of this diversity, initially, we propose to manually select uniformly difficult projects of appropriate complexity. Ultimately, based on the experiences and insights acquired through the manual selection, we envision the development of a systematic methodology based on software metrics to ease the project selection process. Such a systematic methodology will pave the way for the adoption of the OSS-based approach at peer institutions, bringing us a step closer to injecting realism into SE projects.","2012","2025-04-25 15:27:23","2025-04-25 15:27:23","","9–12","","","","","","","EduRex '12","","","","IEEE Press","","","","","","","","","Place: Zurich, Switzerland","","","","maintenance; open source software; software metrics; evolution; predictive models","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

What strategies are adopted by the sponsor to influence the organizational structure of free software communities? Two constructs are central to the study: organizational structure and sponsorship. For this research, we adopted case study methodology and three free software communities were studied. In the analysis of the results it was evidenced that sponsors influence decision making, definition of community key roles, and a formalization of norms. In turn, non-sponsored communities were characterized by the centralization and informality of the norms.

This is important for Open Source Software (OSS) projects, which receive contributions from many one-time contributors. Focusing on OSS, our study qualitatively analyzed social barriers that hindered newcomers' first contributions. We defined a conceptual model composed of 58 barriers including 13 social barriers.

This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review, (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects, (iii) 24 responses to a questionnaire sent to 9 OSS projects, and (iv) semi-structured interviews with 36 sub-jects from 14 different projects, including newcomers and experi-enced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practi-tioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteris-tics, reception issues, orientation, technical hurdles, and docu-mentation problems. We could observe recurrent barriers evi-denced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-25 15:27:24","2025-04-25 15:27:24","","51–60","","","","","","","ARES '14","","","","IEEE Computer Society","USA","","","","","","","","","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Free open source software projects generally have one mailing list for developers and another one for users. This large number of mailing lists changes constantly and shows a great variety with respect to membership and topics covered. This makes them very difficult to monitor. One way of overcoming this Big Data Challenge is to identify some easily computable global indicators that can be used for instance to detect important events. We illustrate this approach here by making a social network analysis and comparison of developers' and users' mailing lists of four free open source software projects: CentOS, GnuPG, Mailman and Samba. We show that these mailing lists have some common characteristics: the number of messages, the time durations and the interlink times can be fitted using power and lognormal laws with suitable scales and parameters, for the interlink time, the analysis is done using the temporal delta density inspired by the delta density introduced by Viard and Latapy. This similarity between the characteristics of mailing lists also applies to the structure of dominant groups. For the time evolution of the number of messages, GnuPG exhibits a particular behavior. The interpretation of the different parameters gives very interesting insights into the membership and the type of topics covered by the mailing lists. The analysis carried out here and similar studies cited in this paper can therefore be considered as a first step towards the designing of building blocks for monitoring mailing lists.","2015","2025-04-25 15:27:24","2025-04-25 15:27:24","","728–732","","","","","","","BIGDATACONGRESS '15","","","","IEEE Computer Society","USA","","","","","","","","","","","","Big data; mailing list; characteristic time; complementary cumulative distribution; delta density; discussion thread; dominant member; free open source software project; lognormal law; outstanding event detection; power law","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our paper shows how politeness theory can be extended to the âpracticeâ of coding and non-coding work, and provides FLOSS communities with guidelines for involving and sustaining women participants in FLOSS development.","2013","2025-04-25 15:27:24","2025-04-25 15:27:24","","3168–3177","","","","","","","HICSS '13","","","","IEEE Computer Society","USA","","","","","","","","","","","","distributed collaboration; Free/Libre Open Source Software","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The work first explores the emergence and experience of conflict during the life cycle of a project. Different types and sources of conflict are identified, as well as their relationship with group outcomes. Various conflict types are expected to affect group function differently: some conflict sources may present a challenge, while others may prove necessary for successful group function. The dissertation expands theory and research on distributed work, in examining on-going processes of conflict in voluntary teams.

Our results indicate that FOSS project members possess rather sophisticated notions of software usability, which collectively mirror definitions commonly found in HCI textbooks. Our study also uncovered a wide range of practices that ultimately work to improve software usability. Importantly, these activities are typically based on close, direct interpersonal relationships between developers and their core users, a group of users who closely follow the project and provide high quality, respected feedback. These relationships, along with positive feedback from other users, generate social rewards that serve as the primary motivations for attending to usability issues on a day-to-day basis.

By mining 150 thousand commits from the Apache Software Foundation repository and employing object-oriented metrics reference values, we concluded that 91% of all established logical dependencies involve non-structurally related artifacts.

Based on the revision data of 22 OSS projects, we tracked the evolution of language usage and other artefacts such as documentation files, binaries and graphics files. In these systems several different languages and artefact types including C/C++, Java, XML, XSL, Makefile, Groovy, HTML, Shell scripts, CSS, Graphics files, JavaScript, JSP, Ruby, Phyton, XQuery, OpenDocument files, PHP, etc. have been used. We found that the amount of code written in different languages differs substantially. Some of our findings can be summarized as follows: (1) JavaScript and CSS files most often co-evolve with XSL; (2) Most Java developers but only every second C/C++ developer work with XML; (3) and more generally, we observed a significant increase of usage of XML and XSL during recent years and found that Java or C are hardly ever the only language used by a developer.

Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage.

With the emergence and popularity growth of social Q&A sites such as the StackExchange network (e.g., StackOverflow), this is beginning to change. Such sites offer different socio-technical incentives to their participants than mailing lists do, e.g., rich web environments to store and manage content collaboratively, or a place to showcase their knowledge and expertise more vividly to peers or potential recruiters. A key difference between StackExchange and mailing lists is gamification, i.e., StackExchange participants compete to obtain reputation points and badges. In this paper, we use a case study of R (a widely-used tool for data analysis) to investigate how mailing list participation has evolved since the launch of StackExchange. Our main contribution is the assembly of a joint data set from the two sources, in which participants in both the textttr-help mailing list and StackExchange are identifiable. This permits their activities to be linked across the two resources and also over time. With this data set we found that user support activities show a strong shift away from textttr-help. In particular, mailing list experts are migrating to StackExchange, where their behaviour is different. First, participants active both on textttr-help and on StackExchange are more active than those who focus exclusively on only one of the two. Second, they provide faster answers on StackExchange than on textttr-help, suggesting they are motivated by the emphgamified environment. To our knowledge, our study is the first to directly chart the changes in behaviour of specific contributors as they migrate into gamified environments, and has important implications for knowledge management in software engineering.","2014","2025-04-25 15:27:25","2025-04-25 15:27:25","","342–354","","","","","","","CSCW '14","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Baltimore, Maryland, USA","","","","open source; crowdsourced knowledge; gamification.; mailing lists; a; social q&","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The objective of this review is to obtain an overview of the existing studies in open source software evolution, with the intention of achieving an understanding of how software evolvability (i.e., a software system’s ability to easily accommodate changes) is addressed during development and evolution of open source software. The primary studies for this review were identified based on a pre-defined search strategy and a multi-step selection process. Based on their research topics, we have identified four main categories of themes: software trends and patterns, evolution process support, evolvability characteristics addressed in OSS evolution, and examining OSS at software architecture level. A comprehensive overview and synthesis of these categories and related studies is presented as well.","2010","2025-04-25 15:27:25","2025-04-25 15:40:43","","356–365","","","","","","","APSEC '10","","","","IEEE Computer Society","USA","","","","","","","","","","","","software evolution; open source software; systematic review; evolvability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To detect such vulnerabilities, finding OSS reuses in COTS software has become imperative. While scalable to tens of thousands of OSS projects, existing binary-to-source matching approaches are severely imprecise in analyzing COTS software products, since they support only a limited number of code features, compute matching scores only approximately in measuring OSS reuses, and neglect the code structures in OSS projects.We introduce a novel binary-to-source matching approach, called B2SFinder1, to address these limitations. First of all, B2SFinder can reason about seven kinds of code features that are traceable in both binary and source code. In order to compute matching scores precisely, B2SFinder employs a weighted feature matching algorithm that combines three matching methods (for dealing with different code features) with two importance-weighting methods (for computing the weight of an instance of a code feature in a given COTS software application based on its specificity and occurrence frequency). Finally, B2SFinder identifies different types of code reuses based on matching scores and code structures of OSS projects. We have implemented B2SFinder using an optimized data structure. We have evaluated B2SFinder using 21991 binaries from 1000 popular COTS software products and 2189 candidate OSS projects. Our experimental results show that B2SFinder is not only precise but also scalable. Compared with the state of the art, B2SFinder has successfully found up to 2.15x as many reuse cases in 53.85 seconds per binary file on average. We also discuss how B2SFinder can be leveraged in detecting OSS reuse vulnerabilities in practice.","2020","2025-04-25 15:27:25","2025-04-25 15:46:34","","1038–1049","","","","","","","ASE '19","","","","IEEE Press","","","","","","","","","Place: San Diego, California","","","","OSS; binary-to-source matching; code feature; code reuse; COTS software; one-day vulnerability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 700,000 bug reports obtained from the Bugzilla installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3% with an associated recall of 38.9%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.","2013","2025-04-25 15:27:26","2025-04-25 15:27:26","","1032–1041","","","","","","","ICSE '13","","","","IEEE Press","","","","","","","","","Place: San Francisco, CA, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Besides some much-reported benefits of this approach, using OSS products also presents new challenges. One such challenge is identifying relevant, high-quality OSS products among the hundreds of thousands that are available. One approach for doing that is to identify architectural patterns, since these patterns have a direct effect on a product's quality attributes, such as performance and reliability. However, there are no well-defined methods or tools available to identify architectural patterns.Research aim: Our goal is to identify approaches taken by novice software engineers that have no or little experience in identifying architectural patterns. We aim to get insight into how these novices tackle this problem, what challenges they encounter and what suggestions they have for improving this process.Method: We collected data from seven M. Sc. student teams that performed a pattern identification assignment. We conducted semi-structured interviews with eight students from two teams. We studied reflection reports from four teams that reported their experiences as part of their final report. Furthermore, during his M. Sc. course, one of the authors performed the assignment as a member of a team. We also included his experiences.Results and conclusions: We identified a number of approaches that students have taken in order to identify architectural patterns, as well as a number of challenges that they encountered in this task. Furthermore, based on suggestions from the students, we present a proposal to improve this process.","2010","2025-04-25 15:27:26","2025-04-25 15:27:26","","91–100","","","","","","","EASE'10","","","","BCS Learning & Development Ltd.","Swindon, GBR","","","","","","","","event-place: UK","","","","challenges; approaches; architectural patterns; pattern identification","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Determining the license of a package and assessing whether it depends on other software with incompatible licenses is not trivial. Although this task has been done in a labor intensive manner by software distributions, automatic tools to perform this analysis are highly desired. This paper proposes a method to understand licensing compatibility issues in software packages, and reports an empirical study aimed at auditing licensing issues in binary packages of the Fedora-12 GNU/Linux distribution. The objective of this study is (i) to understand how the license declared in packages is consistent with those of source code files, and (ii) to audit the licensing information of Fedora-12, highlighting cases of incompatibilities between dependent packages. The obtained results—supported by feedback received from Fedora contributors—show that there exist many nuances in determining the license of a binary package from its source code, as well as cases of license incompatibility issues due to package dependencies.","2010","2025-04-25 15:27:26","2025-04-25 15:27:26","","84–93","","","","","","","ICPC '10","","","","IEEE Computer Society","USA","","","","","","","","","","","","evolution; empirical study; mining software repositories; open source system; Software licensing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Universally accessible browsers require novel interaction modalities and additional functionalities, for which existing browsers tend to provide only partial solutions. Although functionality for Web accessibility can be found as open source and free software components, their reuse and integration is complex because they were developed in diverse implementation environments, following standards and conventions incompatible with the Web.To enable the integration of existing partial solutions within a mainstream Web browser environment, we have developed a middleware infrastructure, AMICO:WEB. This enables browser access to a wide variety of open source and free software components. The main contribution of AMICO:WEB is in enabling the syntactic interoperability between Web extension mechanisms and a variety of integration mechanisms used by open source and free software components. It also bridges the semantic differences between the high-level world of Web XML-based APIs and the low-level APIs of the device-oriented world.We discuss the design decisions made during the development of AMICO:WEB in the context of Web accessibility, using two typical usage scenarios: one describing a disabled user using a mainstream Web browser with additional interaction modalities; another describing a non-disabled user browsing in a suboptimal interaction situation.","2007","2025-04-25 15:27:27","2025-04-25 15:27:27","","15–24","","","","","","","W4A '07","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Banff, Canada","","","","open source software; user interfaces; middleware; software platform; web accessibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Introducing new technologies requires a ""proof of concept"" process in order to decide on the profitability of further development. Using Open Source software solutions in the BL helped make this process quicker and more efficient.The BL has been developing its proprietary Computer Generated Forces (CGF) for approximately 10 years. This CGF is mainly intended for simulating ground entities and has various capabilities for autonomous movement. Over the years, as the visual systems have improved and due to the introduction of urban environments simulation, the need for realistic movement characteristics, especially human, became important. An in-house solution, developed by the CGF team, appeared to consume too much development effort and was not extendable enough. After analyzing the problem and reviewing various third-party solutions, the CGF team decided on using an Open Source (OS) library called OpenSteer.Until recently, ground vehicle simulations in the BL used a low fidelity non-physical movement mode, based on ground clamping. In 2006 the BL got involved in research areas related to Unmanned Ground Vehicles (UGVs) and human-robotics interactions. During early research stages it became clear that it would be necessary to simulate the UGV dynamics in higher fidelity than was done before. The development team decided to initiate the ""proof of concept"" process before full scale development. Therefore a quick solution for a high-fidelity vehicle simulation was searched for. After a brief review of third party solutions, an OS library, Open Dynamics Engine (ODE) was chosen. Developing a UGV simulation required an autonomous movement model which appeared to have similar characteristics to the one developed by the CGF team based on OpenSteer. Since OpenSteer was not originally intended for simulating rigid-body vehicles, the development team faced the challenge of integrating both products, OpenSteer and ODE. This paper will describe the steps taken in order to assimilate OS products in the BL simulation test-bed and lessons learned.","2008","2025-04-25 15:27:27","2025-04-25 15:27:27","","","","","","","","","SCSC '08","","","","Society for Modeling & Simulation International","Vista, CA","","","","","","","","event-place: Edinburgh, Scotland","","","","open source software; licenses; copyleft; BSD; CGF; feasibility study; GPL; ground vehicle modeling; IDF Battle Lab; movement modeling; ODE; OpenSteer; test-bed; wrappers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper highlights the valuable semantic information of project descriptions and labels, proposes labeled software topic detection (LSTD), a hybrid approach combining topic models and ranking mechanisms to detect and enrich the topics of software by mining the large amount of textual software profiles, which can be employed to do software categorization and tag recommendation. L-STD makes use of labeled LDA to capture the semantic correlations between labels and descriptions and then construct the label-based topic-word matrix. Based on the generated matrix and the generality of labels, LSTD designs a simple yet efficient algorithm to detect the latent topics of software that expressed as relevant and popular labels. Comprehensive evaluations are conducted on the large-scale datasets of representative open source communities and the results validate the effectiveness of LSTD.","2012","2025-04-25 15:27:27","2025-04-25 15:27:27","","17–24","","","","","","","SoftwareMining '12","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Beijing, China","","","","open source software; topic detection; topic model; labeled LDA; software profile","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers from a variety of disciplines have turned their attention to the phenomenon of OSS development as a successful and intriguing form of Internet supported work.","2007","2025-04-25 15:27:27","2025-04-25 15:27:27","","165","","","","","","","HICSS '07","","","","IEEE Computer Society","USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper presents the state of the art of how to combine MDD methods with OS software development. The approach is called Open Models software development which is expected to combine the benefits of both worlds. The fundamental idea of Open Models development is to apply community-driven collaborative MDD. In this paper, Open Models development is exemplified by constructing Resource Availability Service (RAS). RAS is a web service for providing availability information about resources such as services, content, users and terminals.

For every type of application, there are a wide variety of alternatives. We observed that even if different applications that perform similar tasks and compiled with the same versions of the compiler and the libraries, they perform very differently while running on the same system. Sadly prior work in this area that compares two code bases for similarities does not help us in finding the reasons for the differences in performance.In this paper, we develop a tool, SoftMon, that can compare the codebases of two separate applications and pinpoint the exact set of functions that are disproportionately responsible for differences in performance. Our tool uses machine learning and NLP techniques to analyze why a given open-source application has a lower performance as compared to its peers, design bespoke applications that can incorporate specific innovations (identified by SoftMon) in competing applications, and diagnose performance bugs.In this paper, we compare a wide variety of large open-source programs such as image editors, audio players, text editors, PDF readers, mail clients and even full-fledged operating systems (OSs). In all cases, our tool was able to pinpoint a set of at the most 10-15 functions that are responsible for the differences within 200 seconds. A subsequent manual analysis assisted by our graph visualization engine helps us find the reasons. We were able to validate most of the reasons by correlating them with subsequent observations made by developers or from existing technical literature.

Although a large number of security learning materials are widely available in books, open literature or on the Internet, they are difficult for learners to understand the rationale of security topics and correlate the concepts with real software scenarios. We argue that the traditional approach, which usually organizes knowledge content topically, with security-centric, is not suitable to motivate learners and stimulate learners' interest. To tackle this learning issue, our research is focused on forging a contextualized learning environment for software security where learners can explore security knowledge and relate it to the context that they are familiar with. This learning system is developed base on our proposed context-based learning approach and based on ontological technologies. In this paper, we present our evaluation study in the open source software (OSS) development environment.

Participating in an existing HFOSS project, although ripe with learning opportunities, presents a number of hurdles for faculty and students. An alternative to joining an existing HFOSS project community is to participate in a faculty-led HFOSS project. These projects provide the instructor with more control over the learning environment, but often lack an active community outside of the classroom. This paper describes a multi-institutional effort to engage a community of developers in creating humanitarian open source projects to support their on-campus food pantries. Food insecurity on campus has become a national concern and many institutions have, or are starting, food pantries to support the student, staff, and faculty community. Starting a faculty-led HFOSS project involves making decisions not only about the features of the project but also about community norms, tool choices, project development workflow, and inter-institution cooperation. This paper provides an overview of the creation of LibreFoodPantry, a community who is developing a suite of projects that support on-campus food pantries. It describes instances of using LibreFoodPantry's projects in various classroom settings, the lessons learned from these experiences, and the resulting discussions and decisions made by the LibreFoodPantry Coordinating Committee. This process has led to a community dedicated to easing the on-ramp for faculty who want to help their students contribute to an HFOSS project.","2020","2025-04-25 15:27:28","2025-04-25 15:27:28","","441–447","","","","","","","SIGCSE '20","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Portland, OR, USA","","","","open source; software development; project management; computing for social good","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, a balance should be considered between the software cost and the cost of its technical support and reliability. In this article, a maintenance system for wind farms will be presented. It is connected to an information system for maintenance, called SMIT (Terology Integrated Modular System) as a general base to manage the assets and as a support strategic line to the evolution of this system, which incorporates on-condition maintenance modules, and the support to the research and development done around this theme. The SMIT system is based on a TCP/IP network, using a Linux server running a PostgreSQL database and Apache web server with PHP, and Octave and R software for numerical analysis. Maintenance technicians, chiefs, economic and production management personnel can access SMIT database through SMIT clients for Windows. In addition, this maintenance system for wind systems uses also special low cost hardware for data acquisition on floor level. The hardware uses a distributed TCP/IP network to synchronize SMIT server master clock through Precision Time Protocol. Usually, the manufactures construct, deploy and give the means for the suppliers to perform the wind system's maintenance. This is a very competitive area, where companies tend to hide the development details and implementations. Within this scenario, the development of maintenance management models for multiple wind equipments is important, and will allow countries to be more competitive in a growing market.

The objective: to explore the evolution of a long-lived open source project with the intention of learning how code evolution has progressed over time. This investigation provides a case study of Nethack, an enormously popular open source game that has been in development for more than a decade. The Goal Question Metric approach was employed to derive measurement goals for the evaluation of open source software (OSS) evolution in Nethack. According to Lehman's laws, the incremental growth size of successive releases tends to decline during the active life of an evolving program. Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased. These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased. These findings raise questions concerning the evolution of other OSS applications.","2006","2025-04-25 15:27:29","2025-04-25 15:27:29","","47–58","","","","","","","SEW '06","","","","IEEE Computer Society","USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They started by identifying key variables and their relationship, and mining data from the communities whose software solutions have been successfully implemented in the municipalities according to player reports available in BPS portal. Such as the relationships demonstrate, these players have been appropriated the knowledge related to solutions and created new business to support the modernization of public administration. Based on reports and statistical analysis, the authors could understand both the dynamic of the successful communities and the adoption phenomena by municipalities as a consequence of individual initiatives.

In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules.

At the same time, many software organizations are applying Scrum software development practices, for productivity and quality gains. Scrum calls for self-organizing teams, in which the development team has total control over its development process. However, OSS projects typically have their own processes and standards, which might not mesh well with a company's internal processes, such as Scrum. This paper presents an experience report from Sony Interactive Entertainment (SIE), where the ""toolchain CPU compiler"" team directly participates in the ""LLVM"" OSS project. The team ran into a number of difficulties when using Scrum to manage their development. In particular, the team often failed to complete Scrum sprints where tasks required interaction with the open source community. We look at how the team redefined task flows to alleviate these difficulties, and eventually evolved a highly modified process, dubbed TWINS (This Workflow Is Not Scrum). We assess the revised process, and compare it to other established agile methods, finding it bears a strong resemblance to Scrumban (the SIE team was not aware of Scrumban previously).

Given this fundamental initial paradox, it is perhaps hardly surprising that the OSS concept is characterised by contradictions, paradoxes and tensions throughout.

This paper summarizes our preliminary investigations into the evolution of the best known open source system: the Linux operating system kernel. Because Linux is large (over two million lines of code in the most recent version) and because its development model is not as tightly planned and managed as most industrial software processes, we had expected to find that Linux was growing more slowly as it got bigger and more complex. Instead, we have found that Linux has been growing at a super-linear rate for several years.

In this paper, we investigate how and why quasi-contributors (external developers who did not succeed in getting their contributions accepted to an OSS project) fail. To achieve our goal, we collected data from 21 popular, non-trivial GitHub projects, identified quasi-contributors, and analyzed their pull-requests. In addition, we conducted surveys with quasi-contributors, and projects' integrators, to understand their perceptions about nonacceptance. We found 10,099 quasi-contributors — about 70% of the total actual contributors — that submitted 12,367 nonaccepted pull-requests. In five projects, we found more quasi-contributors than actual contributors. About one-third of the developers who took our survey disagreed with the nonacceptance, and around 30% declared the nonacceptance demotivated or prevented them from placing another pull-request. The main reasons for pull-request nonacceptance from the quasi-contributors' perspective were ""superseded/duplicated pull-request"" and ""mismatch between developer's and team's vision/opinion."" A manual analysis of a representative sample of 263 pull-requests corroborated with this finding. We also found reasons related to the relationship with the community and lack of experience or commitment from the quasi-contributors. This empirical study is particularly relevant to those interested in fostering developers' participation and retention in OSS communities.","2018","2025-04-25 15:27:30","2025-04-25 15:42:41","","256–266","","","","","","","ICSE '18","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Gothenburg, Sweden","","","","newcomers; open source software; pull-requests; quasi-contributors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to reduce the mean time to resolve bugs, managers/leaders of open source projects need to identify and understand the bottleneck of a bug modification process in their own projects. In this paper, we propose an analysis method which represents a bug modification process using a bug tracking system as a state transition diagram and then calculates the amount of time required to transit between states.

System changes are often done without considering their effects on the system structure. These changes often introduce structural anomalies between the concrete (as-built) and the conceptual (as-designed) architecture, which can impede program understanding. The problem of architectural drift is especially pronounced in open source systems, where many developers work in isolation on distinct features with little co-ordination. In this paper, we present our experiences with repairing the architectures of two large open source systems (the Linux operating system kernel and the VIM text editor) to aid program understanding. For both systems, we were successful in removing many structural anomalies from their architectures.","2000","2025-04-25 15:27:31","2025-04-25 15:45:44","","48","","","","","","","IWPC '00","","","","IEEE Computer Society","USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this position paper, we present a short summary of two recent projects.First, we have performed a case study on the evolution of the Linux kernel [3], as well as some other open source software (OSS) systems. We have found that several OSS systems appear not to obey some of ""Lehman's laws"" of software evolution [5, 7], and that Linux in particular is continuing to grow at a geometric rate. Currently, we are working on a detailed study of the evolution of one of the subsystems of the Linux kernel: the SCSI drivers subsystem. We have found that cloning, which is usually considered to be an indicator of lazy development and poor process, is quite common and is even considered to be a useful practice.Second, we are developing a tool called Beagle to aid software maintainers in understanding how large systems have changed over time. Beagle integrates data from various static analysis and metrics tools and provides a query engine as well as navigable visualizations.

We analyze the trade-off between early and late release based on a two-sided network externality that explores how the release of free information benefits those who develop as well as those who consume.

However, many other FLOSS projects exist which provide a very rich body to study and understand. By focusing on more projects that perhaps do not gain the immediate attention of researchers, we hope to broaden our knowledge of the rich ecosystems within FLOSS.Specifically, the goal of the FLOSS-3 workshop (8th in a series at ICSE) is to bring together academic researchers, industry members, and FLOSS developers for the purpose of discussing topics including analyzing ""competing"" projects within FLOSS that share the same domain, performing data collection and analysis among many FLOSS projects, examining governance models within FLOSS projects, identifying licensing paradigms of FLOSS projects, discussing the interplay of corporate involvement within FLOSS projects, social and technical interactions between FLOSS projects, and dependency analysis and reuse between FLOSS projects.We believe that this workshop will also serve as a common bridge between the ACM/IEEE (ICSE) and (IFIP) OSS research communities, thereby providing a window for others in the Software Engineering community to interact with and learn more about the advances of research into FLOSS development and communities.","2010","2025-04-25 15:27:32","2025-04-25 15:27:32","","","","","","","","","","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Being able to identify the core members of a FLOSS development project is important because many of the processes necessary for successful projects likely involve core members differently than peripheral members, so analyses that mix the two groups will likely yield invalid results. We compare 3 analysis approaches to identify the core: the named list of developers, a Bradford's law analysis that takes as the core the most frequent contributors and a social network analysis of the interaction pattern that identifies the core in a core-and-periphery structure. We apply these measures to the interactions around bug fixing for 116 SourceForge projects. The 3 techniques identify different individuals as core members; examination of which individuals are identified leads to suggestions for refining the measures. All 3 measures though suggest that the core of FLOSS projects is a small fraction of the total number of contributors.","2006","2025-04-25 15:27:32","2025-04-25 15:27:32","","118.1","","","","","","","HICSS '06","","","","IEEE Computer Society","USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper develops a model where users choosing between proprietary software and OSS are heterogeneous in their expertise. The paper finds that as users become more skilled in OSS, the price of proprietary software will decline. Second, the equilibrium market structure is influenced by both users' expertise and network effects. It is not surprising that proprietary software can drive OSS out of the market in presence of network effect, but counter-intuitively, this happens when users are highly skilled in OSS. Third, in presence of network effect, OSS may survive in the market only when it is customizable by skilled users and therefore provides significant higher benefits to users than proprietary software.","2006","2025-04-25 15:27:32","2025-04-25 15:27:32","","166.1","","","","","","","HICSS '06","","","","IEEE Computer Society","USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Refactoring refers to the restructuring of software according to specific mechanics and principles. In this paper, we describe a tool that allows refactoring data across multiple versions of seven open-source software systems to be collected. The tool automates the identification of refactorings as program transformations between consecutive software releases. The same tool thus allowed an empirical analysis of software development across versions from the perspective of those transformations. We describe results for the systems analysed and point to key conclusions from our analysis. In particular, we investigate a problematic empirical question as to whether certain refactorings are related, i.e., they cannot be undertaken in isolation without other refactorings being undertaken in parallel. In this context, we focus specifically on the four most common refactorings identified by the tool from three of the open-source systems and use a dependency graph to inform conclusions about the empirical data extracted by the tool. An interesting result relating to some common refactorings is described.","2006","2025-04-25 15:27:32","2025-04-25 15:27:32","","1713–1720","","","","","","","SAC '06","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Dijon, France","","","","empirical analysis; dependencies; refactoring; object-oriented; tool","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It was found that peer review is generally considered very useful for detecting both defects and flaws in code, as well as being important in contributing to the quality of the software. It is suggested that OSS developers commit to quality through internalization - adopting the ideas as their own, as the majority of the developers indicated that they would perform peer reviews without management direction. Encouragement to perform peer reviews and an organizational culture of peer review make it more likely for the developers to perform peer review under their own initiative, but neither are essential.","2002","2025-04-25 15:27:33","2025-04-25 15:27:33","","340–350","","","","","","","ECSQ '02","","","","Springer-Verlag","Berlin, Heidelberg","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, we attempt to predict field defects by extending a software reliability model fitted to development defects. We find this approach to be infeasible, which motivates examining metrics-based field defect prediction. Then, we evaluate 139 predictors using established statistical methods: Kendallýs rank correlation, Pearsonýs rank correlation, and forward AIC model selection. The metrics we collect include product metrics, development metrics, deployment and usage metrics, and software and hardware configurations metrics. We find the number of messages to the technical discussion mailing list during the development period (a deployment and usage metric captured from mailing list archives) to be the best predictor of field defects.

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization that naturally fix them during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-25 15:27:33","2025-04-25 15:27:33","","97–106","","","","","","","DSN '00","","","","IEEE Computer Society","USA","","","","","","","","","","","","Software; Faults; Heisenbugs; Recovery; Transient","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The contributors in a free software project exhibit different levels of participation in the project, and can be categorized as core and peripheral developers. Research aim: This research aims at characterising the changes made to the source code of 7 web server projects written in C with respect to the amount of structural complexity added or removed and the developer level of participation. Method: We performed a observational study with historical data collected from the version control repositories of those projects, recording structural complexity information for each change as well as identifying each change as performed by a core or a peripheral developer. Results and conclusions: We have found that core developers introduce less structural complexity than peripheral developers in general, and that in the case of complexity-reducing activities, core developers remove more structural complexity than peripheral developers. These results demonstrate the importance of having a stable and healthy core team to the sustainability of free software projects.","2010","2025-04-25 15:27:33","2025-04-25 15:27:33","","21–29","","","","","","","SBES '10","","","","IEEE Computer Society","USA","","","","","","","","","","","","FLOSS; Free Software; Open Source software; Empirical Software Engineering; Core and Periphery; Structural Complexity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This rise to prominence can be attributed to the high quality and suitability of the software. This quality and suitability is achieved through an elaborate peer-review process performed by a large community of users, who act as co-developers to identify and correct software defects and add features. Although this process is crucial to the success of free software projects, there is more to the free software development than the creation of a 'bazaar'. In this paper we draw on existing free software projects to define a lifecycle model for free software. This paper then explores each phase of the lifecycle model and agrees that, while the bazaar phase attracts the most attention, it is the initial modular design that accommodates diverse interventions. Moreover, it is the period of transition from the initial group to the larger community based development that is crucial in determining whether a free software project will succeed or fail.","2004","2025-04-25 15:27:33","2025-04-25 15:27:33","","84–91","","","","","","","APSEC '04","","","","IEEE Computer Society","USA","","","","","","","","","","","","free software; development process; software lifecycle","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our methods are based on complex network and time-series analysis. We define the notion of a working rhythm as the average time spent on a commit task and we study the correlation between working rhythm and communication frequency. We build communication networks for code developers, and find that the developers with higher social status, represented by the nodes with larger number of outgoing or incoming links, always have faster working rhythms and thus contribute more per unit time to the projects. We also study the dependency between work (committing) and talk (communication) activities, in particular the effect of their interleaving. We introduce multi-activity time-series and quantitative measures based on activity latencies to evaluate this dependency. Comparison of simulated time-series with the real ones suggests that when work and talk activities are in proximity they may accelerate each other in OSS systems. These findings suggest that frequent communication before and after committing activities is essential for effective software development in distributed systems.","2012","2025-04-25 15:27:33","2025-04-25 15:27:33","","78–85","","","","","","","SOCIALINFORMATICS '12","","","","IEEE Computer Society","USA","","","","","","","","","","","","social network; open source software; committing rhythm; time-series; work and talk","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To verify these relationships, we analyzed 6,773 Free Software projects from the SourceForge.net repository. The results indicated that attractiveness is indeed correlated to some source code metrics. This suggests that measurable attributes of the project source code somehow affect the decision to contribute and adopt a Free Software project.

Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

Our results further suggest that service level agreements and process governance are good tools to guarantee satisfactory processing times.","2010","2025-04-25 15:27:34","2025-04-25 15:27:34","","188–197","","","","","","","COMPSAC '10","","","","IEEE Computer Society","USA","","","","","","","","","","","","empirical analysis; open source software; closed source software; development teams; failure processing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Floss-refactorings can be error-prone and require careful handling. However, little has been done to understand how refactorings and extra edits relate in practice. In this work, we propose a strategy for extracting floss-refactoring data. Moreover, we mine code repositories of 16 open-source projects and analyse commits with floss refactoring related to Extract Method. Our results show that developers often combine Extract Method with inner method extra edits (e.g., statement insert), with an expected increase of 8-16% of extra edits by each Extract Method.

The results indicate that real networks are mainly characterized by the modular small-world structure, which is inherently correlated with the sub-project participation of developers. Most module members are single-dimensional developers whose coding-collaboration focuses on a small number of sub-projects (called the main dimension of the module), while a small proportion of module members are multi-dimensional developers who conduct coding-collaboration in the main dimension of different modules.

Currently, FAQ chatbot is the most popular domain of use of dialog assistants. However, developing a chatbot project requires a full-stack team formed by numerous specialists, such as dialog designer, data scientist, software engineer, DevOps, business strategist and experts from the domain, which can be both time and resources consuming. Language processing can be particularly challenging in languages other than English due to the scarcity of training datasets.Most of the requirements of FAQ chatbots are similar, domain-specific, and projects could profit from Open Source Software (OSS) reuse. In this paper, we examine how OSS FAQ chatbot projects can benefit from reuse at the project level (black-box reuse). We present an experience report of a FLOSS FAQ chatbot project developed in Portuguese to an e-government service in Brazil. It comprises of the chatbot distribution service, as well as for analytics tool integrated and deployed on-premises. We identified assets that could be reused as a black-box and the assets that should be customized for a particular application. We categorized these assets in architecture, corpus, dialog flows, machine learning models, and documentation. This paper discusses how automation, pre-configuration, and templates can aid newcomers to develop chatbots in Portuguese without the need for specialized skills required from tools in chatbot architecture. Our main contribution is to highlight the issues non-English FAQ chatbots projects will likely face and the assets that can be reused. It allows non-chatbot experts to develop a quality-assured OSS FAQ chatbot in a shorter project cycle.","2019","2025-04-25 15:27:35","2025-04-25 15:27:35","","","","","","","","","OpenSym '19","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Skövde, Sweden","","","","open source; FLOSS; OSS; e-government; black-box reuse; conversational agents; experience report; FLOSS FAQ chatbot; portuguese chatbot","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Companies get involved in FLOSS projects to acquire user innovations [3, 12], to reduce costs [8, 11], to make money on complementary services [13], etc. Such intense involvement may change the nature of FLOSS development and pose critical challenges for the sustainability of the projects. For example, it has been found that a company's full control and intense involvement is associated with a decrease of volunteer inflow [13]. Sometimes a project may fail after one company pulls resources from the project [13]. This raises concerns about the domination of one company in a project. In large projects like OpenStack, there are often hundreds of companies involved in contributing code. Despite substantial researches on commercial participation, whether or not one company dominates a project and the impact of such domination has never been explicitly explored. We investigate four main projects of OpenStack, a large ecosystem that has had a tremendous impact on computing and society, to answer the following research questions: Does one company dominate the project's development (RQ1)?

I trace the learning trajectories of two participants from high school until they enter the professional workforce and beyond. I argue that FLOSS participation represents an ideal networked form of learning as it provides both socio-cognitive support for short term activities and also socio-temporal support for long term participation and learning.

Aims: In this paper, we examine the extent to which these problems still exist. We also study male and female contributors' perceptions of other contributors. Method: We surveyed participants from 15 FLOSS projects, asking a series of open-ended, closed-ended, and behavioral scale questions to gather information about the issue of gender in FLOSS projects. Results: Though many of those we surveyed expressed a positive sentiment towards females who participate in FLOSS projects, some were still strongly against their inclusion. Often, the respondents who were against inclusiveness also believed their own sentiments were the prevailing belief in the community, contrary to our findings. Others did not see the purpose of attempting to be inclusive, expressing the sentiment that a discussion of gender has no place in FLOSS. Conclusions: FLOSS projects have started to move forwards in terms of gender acceptance. However, there is still a need for more progress in the inclusion of gender-diverse contributors.","2019","2025-04-25 15:27:35","2025-04-25 15:27:35","","677–687","","","","","","","ICSE '19","","","","IEEE Press","","","","","","","","","Place: Montreal, Quebec, Canada","","","","open source; survey; gender; floss","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is unknown which skills are used in OSS development as well as OSS contributors' general attitudes towards skills in OSS. In this paper, we address this gap by administering a survey to a diverse set of 455 OSS contributors. Guided by these responses as well as prior literature on software development expertise and social factors of OSS, we develop a model of skills in OSS that considers the many contexts OSS contributors work in. This model has 45 skills in the following 9 categories: technical skills, working styles, problem solving, contribution types, project-specific skills, interpersonal skills, external relations, management, and characteristics. Through a mix of qualitative and quantitative analyses, we find that OSS contributors are actively motivated to improve skills and perceive many benefits in sharing their skills with others. We then use this analysis to derive a set of design implications and best practices for those who incorporate skills into OSS tools and platforms, such as GitHub.","2022","2025-04-25 15:27:35","2025-04-25 15:27:35","","170–182","","","","","","","ESEC/FSE 2022","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Singapore, Singapore","","","","survey; open source software; empirical study; skills","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level.In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-25 15:27:35","2025-04-25 15:27:35","","2366–2380","","","","","","","CCS '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Copenhagen, Denmark","","","","patch backporting; patch semantics; patch type","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions’ adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file.

Both deeply modify the way the computer resources are made available and monetized. They evolve between competition (e.g. open source software for desktop versus SaaS applications) and complementarity (e.g. cloud solutions based on open source components or cloud applications published under open source license). PaaSage is an open source integrated platform to support both design and deployment of cloud applications. The PaaSage consortium decided to publish the source code as open source. It needed a process for the open source license selection. Open source licensing scheme born before the development of cloud computing and evolved with the creation of new open source licenses suitable for SaaS applications. The license is a part of project governance and strongly influences the life of the project. In the context of the PaaSage European project, the issue of the open source license selection for cloud computing software has been addressed.

Meanwhile, software companies have successfully launched programs like Google Summer of Code (GSoC) and FindBugs ""fixit"" to contribute to open-source projects. Inspired by the success of these programs, we propose GitHub-OSS Fixit, a team-based course project where students are taught to contribute to open-source Java projects by fixing bugs reported in GitHub. We described our course outline to teach students SE concepts by encouraging the usages of several automated program analysis tools. We also included the carefully designed instructions that we gave to students for participating in GitHub-OSS Fixit. As all lectures and labs are conducted online, we think that our course design could help in guiding future online SE courses. Overall, our survey results show that students think that GitHub-OSS Fixit could help them to improve many skills and apply the knowledge taught in class. In total, 154 students have submitted 214 pull requests to 24 different Java projects, in which 93 of them have been merged, and 46 have been closed by developers.","2021","2025-04-25 15:27:36","2025-04-25 15:27:36","","1–10","","","","","","","ICSE-JSEET '21","","","","IEEE Press","","","","","","","","","Place: Virtual Event, Spain","","","","software engineering; open-source software; program repair","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs).

The effect of gender diversity in open source communities has gained increasing attention from practitioners and researchers. For instance, organizations such as the Python Software Foundation and the OpenStack Foundation started actions to increase gender diversity and promote women to top positions in the communities. Problem. Although the general underrepresentation of women (a.k.a. horizontal segregation) in open source communities has been explored in a number of research studies, little is known about the vertical segregation in open source communities—which occurs when there are fewer women in high level positions. Aims. To address this research gap, in this paper we present the results of a mixed-methods study on gender diversity and work practices of core developers contributing to open-source communities. Method. In the first study, we used mining-software repositories procedures to identify the core developers of 711 open source projects, in order to understand how common are women core developers in open source communities and characterize their work practices. In the second study, we surveyed the women core developers we identified in the first study to collect their perceptions of gender diversity and gender bias they might have observed while contributing to open source systems. Results. Our findings show that open source communities present both horizontal and vertical segregation (only 2.3% of the core developers are women). Nevertheless, differently from previous studies, most of the women core developers (65.7%) report never having experienced gender discrimination when contributing to an open source project. Finally, we did not note substantial differences between the work practices among women and men core developers. Conclusions. We reflect on these findings and present some ideas that might increase the participation of women in open source communities.","2020","2025-04-25 15:27:36","2025-04-25 15:27:36","","","","","","","","","ESEM '20","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Bari, Italy","","","","Core Developer; Gender Diversity; OSS Community; Vertical Segregation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hence, there is a constant race for defenders to find and patch them before attackers are able to exploit them. Measuring different aspects of this process is important in order to better understand it and improve the odds for defenders. (Aims) The human factor of the vulnerability discovery and patching process has received limited attention. Better knowledge of the characteristics of the people and organizations who discover and report security vulnerabilities can considerably enhance our understanding of the process, provide insights regarding the expended effort in vulnerability hunting, contribute to better security metrics, and help guide practical decisions regarding the strategy of projects to attract vulnerability researchers.(Method) In this paper, we present what is, to the best of our knowledge, the first large-scale empirical study on the people and organizations who report vulnerabilities in popular FLOSS projects. Collecting data from a multitude of publicly available sources (NVD, bug-tracking platforms, vendor advisories, source code repositories), we create a dataset of reporter information for 2193 unique reporting entities of 4756 CVEs affecting the Mozilla suite, Apache httpd, the PHP interpreter, and the Linux kernel. We use the dataset to investigate several aspects of the vulnerability discovery process, specifically regarding the distribution of contributions, their temporal characteristics, and the motivations of reporters.(Results) Among our results: around 80% of reports come from 20% of reporters; first time reporters are significant contributors to the yearly total in all 4 projects; productive reporters are specialized w.r.t. the project and vulnerability types; around half of all reports come from reporters acknowledging an affiliation.(Conclusions) Projects depend both on a core of dedicated and productive reporters, and on small contributions from a large number of community reporters. The generalized Pareto principle (the (1 - p)/p law) can be used as a metric for the concentration of contributions in the vulnerability-reporting ecosystem of a project.","2021","2025-04-25 15:27:36","2025-04-25 15:27:36","","","","","","","","","ESEM '21","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Bari, Italy","","","","empirical study; security metrics; vulnerability reporters","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Several educators reported its benefits and barriers within different contexts, goals, and areas of knowledge, bringing evidence that it is a feasible approach to address Software Engineering Education challenges.

One-Time Contributors (OTCs), who are on the very fringe of the peripheral developers, are largely unstudied despite offering unique insights into the development process. In a prior survey, we identified OTCs and discovered their motivations and barriers. Aims: The objective of this study is to corroborate the survey results and provide a better understand of OTCs. We compare OTCs to other peripheral and core contributors to determine whether they are distinct. Method: We mined data from the same code-review repository used to identify survey respondents in our previous study. After identifying each contributor as core, periphery, or OTC, we compared them in terms of patch size, time interval from submission to decision, the nature of their conversations, and patch acceptance rates. Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate. The peripheral developers fall in between the OTCs and the core contributors. Conclusion: OTCs do, in fact, face the barriers identified in our prior survey. They represent a distinct group of contributors compared to core and peripheral developers.","2017","2025-04-25 15:27:36","2025-04-25 15:45:52","","1–10","","","","","","","ESEM '17","","","","IEEE Press","","","","","","","","","Place: Markham, Ontario, Canada","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Contrary to traditional education practices, the high-level training required to fulfill this demand should rely on the principle that the learners are themselves responsible for their learning process, that they have control over this process, and that the process aims at developing cross-disciplinary and problem-driven competences, not only at acquiring content knowledge. However, such training requires the presence of a highly interactive, problem-oriented environment for technology-supported learning (or e-learning). This poster presents a doctoral research project, which aims at designing, validating and monitoring a collaborative e-learning environment based on the principles of Free/Libre Open Source Software (FLOSS). In order to validate its outcomes, the project will rely on two real-life professional training programs: in Software Engineering for software managers and in e-Government for public managers.

Given their importance, understanding the resilience of OSS projects is paramount. A primary reason for OSS project failure is the shock caused by the dropout of a core developer, which can jeopardize productivity and project survival. Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer. Our findings underscore the importance of a balanced approach in OSS project management, harmonizing productivity goals with resilience considerations.","2024","2025-04-25 15:27:37","2025-04-25 15:27:37","","706–709","","","","","","","WWW '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Singapore, Singapore","","","","causal inference; resilience; online collaboration networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To keep this foundation intact, the open source community needs to actively invest in sustainable approaches to bring in new contributors and nurture existing ones. We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a ""rising contributor"" badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.Open Source Software (OSS) plays an important role in the development and maintenance of software products that are widely deployed in different domains from computer science to astrophysics and cutting edge medicines research. Chances are there is an open source project for anyone to contribute to. With the recent deployment of the popular Linux open source project on Mars even the sky is no limit. However, OSS projects largely depend on volunteers and attracting, retaining, and keeping contributors engaged is a severe challenge.

It is also studied whether the effort to counteract this complexity is dependent on the repository, and the governance it gives to the hosted projects.The results of the paper are two-fold: on one side, it is shown that the repository hosting larger and more active projects presents more complex structures.

However, there is limited understanding of the factors affecting how developers, and how new or student developers in particular, decide which OSS projects to contribute to, a process critical to OSS sustainability, access, adoption, and growth. To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (𝑝 < 0.0001, effect size = 0.84), student motivation (𝑝 < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (𝑝 < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner. Our findings may help improve the experience for new developers participating in OSS4SG and the quality of their contributions.

The primary difficulty is that software development efforts are complex in terms of both the technical and social aspects of the engineering environment. This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data.

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails.

Typically, the developers create a stable branch for each old stable version, deploy security patches on the branch, and release fixed versions at regular intervals. As such, old-version applications in production environments are protected from the disclosed vulnerabilities in a long time. However, the rapidly growing number of OSS vulnerabilities has greatly strained this patch deployment model, and a critical need has arisen for the security community to understand the practice of security patch management across stable branches. In this work, we conduct a large-scale empirical study of stable branches in OSS projects and the security patches deployed on them via investigating 608 stable branches belonging to 26 popular OSS projects as well as more than 2,000 security fixes for 806 CVEs deployed on stable branches. Our study distills several important findings: (i) more than 80% affected CVE-Branch pairs are unpatched; (ii) the unpatched vulnerabilities could pose a serious security risk to applications in use, with 47.39% of them achieving a CVSS score over 7 (High or Critical Severity); and (iii) the patch porting process requires great manual efforts and takes an average of 40.46 days, significantly extending the time window for N-day vulnerability attacks. Our results reveal the worrying state of security patch management across stable branches. We hope our study can shed some light on improving the practice of patch management in OSS projects.","2022","2025-04-25 15:27:38","2025-04-25 15:27:38","","767–777","","","","","","","WWW '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Virtual Event, Lyon, France","","","","OSS Vulnerabilities; Patch Deployment Study; Security Patches","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Then, we employed a survey (n=30) to map the strategies to challenges and collect additional strategies. Our study identified 7 challenges and 13 strategies related to task recommendation. Strategies such as ""tagging the issues based on difficulty,"" ""adding documentation,"" ""assigning a small task first and then challenge the newcomers with bigger tasks,"" and ""dividing tasks into smaller pieces"" were frequently mentioned as ways to overcome multiple challenges.

Drawing on document-centric approaches we hypothesize that documents supporting asymmetric groups are likely to be more prescriptive and explicate their own use compared to documents supporting symmetric groups. Through exploratory analysis of two kinds of documents, used across three FLOSS projects, we find that documents supporting collaborators with asymmetric knowledge do appear to explicate their own use in more detail.

Alongside this analysis, we propose a novel approach to reuse such existing tests within projects that lack test code, hence leveraging the quality of such projects with minimal developer intervention.

This paper conducted an empirical study of an OSS project-ArgoUML. Unlike most previous studies regarding OSS email archives as a whole social network, our focus is on the quantitative analysis of a series of social networks produced in the process of OSS version evolution and module development.Through the empirical study, we have found that all the social network measures employed in this study are comparable to identify core developers of ArgoUML project. The frequency of co-occurrence of developers within the same topic is not a decisive factor to identify core developers. Developers within the same module communicate closely and frequently with each other. The more modules a developer developed, the more communication he (or she) will have with other developers. Although participants of developers' mailing lists are fluctuating in a large magnitude, the committers of the source code are kept stable in each version evolution. Moreover, the variation of committers of source code in version evolutions is almost unpredictable based on the variation of participants in developers' mailing lists.","2011","2025-04-25 15:27:39","2025-04-25 15:27:39","","71–80","","","","","","","IWPSE-EVOL '11","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Szeged, Hungary","","","","social network; open source; module community; version evolution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work copes with a relevant issue for this architecture, namely unresponsive components because of deadlocks and infinite loops. In particular, a monitor sends heartbeat messages to a component that should reply within a timeout. The timeout choice is tricky, since it should be dynamically adapted to the load conditions of the system. Therefore, our approach is based on an adaptive heartbeat mechanism, in which the timeout is estimated from past response times. We implement and compare three estimation algorithms for the choice of the timeout in the context of the Minix 3 OS.

Empirical software engineering researchers can mine the artifacts from these tools to better understand how FLOSS is made. As the landscape of distributed software development has grown and changed, the tools needed to make FLOSS have changed as well. There are three newer tools at the center of FLOSS development today: distributed version control based forges (like Github), programmer question-and-answer communities (like Stack Overflow), and paste bin tools (like Gist or Pastebin.com). These tools are extending and changing the toolset used for FLOSS development, and redefining what a software forge looks like. The main contributions of this paper are to describe each of these tools, to identify the data and artifacts available for mining from these tools, and to outline some of the ways researchers can use these artifacts to continue to understand how FLOSS is made.","2014","2025-04-25 15:27:39","2025-04-25 15:27:39","","3266–3275","","","","","","","HICSS '14","","","","IEEE Computer Society","USA","","","","","","","","","","","","software development; open source software; stack overflow; github; forges; pastebin; repositories","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The effect of this shift on project organization and developer collaboration is not well understood. In this paper, we use a theoretical argument to evaluate the appropriateness of using DVC in the context of two very common organization forms in OSS: a dictatorship and a peer group. We find that DVC facilitates large hierarchical communities as well as smaller groups of developers, while CVC allows for consensus-building by a peer group. We also find that the flexibility of DVC systems allows for diverse styles of developer collaboration. With CVC, changes flow up and down (and publicly) via a central repository. In contrast, DVC facilitates collaboration in which work output can flow sideways (and privately) between collaborators, with no repository being inherently more important or central. These sideways flows are a relatively new concept. Developers on the Linux project, who tend to be experienced DVC users, cluster around ""sandboxes:"" repositories where developers can work together on a particular topic, isolating their changes from other developers. In this work, we focus on two large, mature OSS projects to illustrate these findings. However, we suggest that social media sites like GitHub may engender other original styles of collaboration that deserve further study.","2013","2025-04-25 15:27:39","2025-04-25 15:27:39","","29–32","","","","","","","RELENG '13","","","","IEEE Press","","","","","","","","","Place: San Francisco, California","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.","2014","2025-04-25 15:27:39","2025-04-25 15:27:39","","401–412","","","","","","","FSE 2014","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Hong Kong, China","","","","sequence analysis; layered network; Markov entropy; structural complexity; Time-series","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We model the individual's chances to become a valuable contributor through their capacity, willingness, and the opportunity to contribute at the time of joining. Using issue tracking data of Mozilla and Gnome, we find that the probability for a new joiner to become a Long Term Contributor (LTC) is associated with her willingness and environment. Specifically, during their first month, future LTCs tend to be more active and show more community-oriented attitude than other joiners. Joiners who start by commenting on instead of reporting an issue or ones who succeed to get at least one reported issue to be fixed, more than double their odds of becoming an LTC. The macro-climate with high project relative sociality and the micro-climate with a large, productive, and clustered peer group increase the odds. On the contrary, the macro-climate with high project popularity and the micro-climate with low attention from peers reduce the odds. This implies that the interaction between individual's attitude and project's climate are associated with the odds that an individual would become a valuable contributor or disengage from the project. Our findings may provide a basis for empirical approaches to design a better community architecture and to improve the experience of contributors.","2012","2025-04-25 15:27:39","2025-04-25 15:27:39","","518–528","","","","","","","ICSE '12","","","","IEEE Press","","","","","","","","","Place: Zurich, Switzerland","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using this perspective, we examine how FLOSS developers' reputation among members within and beyond the project community affects their projects' ability to attract new developers.

From an evolutionary perspective, the picture is unclear - we still know relatively little about how, over time, changes tend to be applied by developers. Our conjecture is that an inheritance hierarchy will tend to grow ‘breadth-wise’ rather than ‘depth-wise’. This claim is made on the basis that developers will avoid extending depth in favour of breadth because of the inherent complexity of having to understand the functionality of superclasses. Thus the goal of our study is to investigate this empirically. We conduct an empirical study of seven Java Open-Source Systems (OSSs) over a series of releases to observe the nature and location of changes within the inheritance hierarchies. Results showed a strong tendency for classes to be added at levels one and two of the hierarchy (rather than anywhere else). Over 96% of classes added over the course of the versions of all systems were at level 1 or level 2. The results suggest that changes cluster in the shallow levels of a hierarchy; this is relevant for developers since it indicates where remedial activities such as refactoring should be focused.","2008","2025-04-25 15:27:40","2025-04-25 15:43:18","","269–278","","","","","","","ASWEC '08","","","","IEEE Computer Society","USA","","","","","","","","","","","","empirical; Evolution; Coupling; cohesion; Inheritance.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.","2021","2025-04-25 15:27:40","2025-04-25 15:27:40","","1020–1032","","","","","","","ICSE '21","","","","IEEE Press","","","","","","","","","Place: Madrid, Spain","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The framework uses 'agents' to represent developers and models the costs associated with first comprehending and then applying necessary changes to a fictitious code base. It also considers agent 'memory recall' of their own code as a fundamental part of the framework and the fact that, with higher numbers of developers, maintenance of a higher proportion of other developers' code (rather than their own) is an inevitable, yet realistic aspect. Through exploration of the results and data produced by the simulation, we are able to explore 'desirable' features that are part of simulating software evolution; as a discussion of the issues raised by the framework, we provide a set of class data from four open-source systems by way of comparison and show that trends in those systems are comparable with results generated by the simulation.

We therefore propose Open Collaborative Data (OCD) - a concept analogous to Open Source Software (OSS) - as a means to share data. In contrast to Open Data (OD), which e.g., governmental agencies provide to catalyze innovation, OCD is shared in open collaboration between commercial organizations, similar to OSS. To achieve this, there is a need for technical infrastructure (e.g., tools for version and access control), licence models, and governance models, all of which have to be tailored for data. However, as data may be sensitive for privacy, anonymization and obfuscation of data is also a research challenge. In this paper, we define the concept of Open Collaborative Data, demonstrate it by map data and image recognition examples, and outline a research agenda for OCD in software engineering as a basis for more efficient evolution of software systems.","2019","2025-04-25 15:27:40","2025-04-25 15:27:40","","25–28","","","","","","","ICSE-NIER '19","","","","IEEE Press","","","","","","","","","Place: Montreal, Quebec, Canada","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For example, end-user reviews help to identify missing features or inform developers about incorrect or unexpected software behavior. We believe that analyzing end-user reviews and utilizing analysis tools are a crucial step towards understanding the complete picture of the quality of a software product, as well as towards reasoning about the evolution history of it. In this paper, we investigate whether both methods correlate with one another. In other words, we explore if there exists a relationship between user satisfaction and the application's internal quality characteristics. To conduct our research, we analyze a total of 46 actual releases of three Android open source software (OSS) applications on the Google Play Store. For each release, we employ multiple static analysis tools to assess several aspects of the application's software quality. We retrieve and manually analyze the complete reviews after each release of each application from its store page, totaling 1004 reviews.

The objective of our work is to understand and model the dynamics of OSS design that take place in mailing list exchanges. We show how quotation practices can be used to locate design relevant data in discussion archives. OSS developers use quotation as a mechanism to maintain the discursive context. To retrace thematic coherence in the online discussions of a major OSS project, Python, we follow how messages are linked through quotation practices.

The Digital Video Broadcast - Return Channel Satellite (DVB-RCS) NetOps vision for remote management and monitoring aims to provide visibility and Situational Awareness to required communities of interest as well as the ability to view and configure all the operational layers DVB-RCS, including the devices and technology, operations and management, and missions and objectives.An effective management and monitoring solution for DVB-RCS must provide the capability to centrally manage and monitor the system, interoperate between SATCOM and terrestrial networks, consolidate technology, standardize processes, and be proactive rather than reactive. The DISN OSS is DISA's enterprise-wide Service Oriented Architecture for information sharing, management, and monitoring capabilities, based on the Telecommunications Management Network industry standards. The DISN OSS puts the information into the hands of the operators and system managers while making the processes, tools, and technology transparent to the consumer.This paper examines how DVB-RCS implemented the NetOps Portal as an immediate and interim solution to provide Situational Awareness to CENTCOM, as well as how leveraging the DISN OSS can help DVB-RCS achieve assured system and network availability, assured information protection, and assured information delivery in support of high-bandwidth, two-way services for the tactical Warfighter.","2009","2025-04-25 15:27:41","2025-04-25 15:27:41","","2378–2384","","","","","","","MILCOM'09","","","","IEEE Press","","","","","","","","","Place: Boston, Massachusetts, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Refactoring refers to the restructuring of software according to specific mechanics and principles. In this paper, we describe an analysis of the results from a tool whose purpose was to identify and extract refactorings from seven open-source Java systems. In particular, we analyzed the mechanics of the most commonly and least commonly applied refactorings to try and account for their frequency. Results showed the most common refactorings of the fifteen coined a 'Gang of Six', to be generally those with a high in-degree and low out-degree when mapped on a dependency graph; the same refactorings also featured strongly in the remedying of bad code smells. Remarkably and surprisingly, inheritance and encapsulationbased refactorings were found to have been applied relatively infrequently - we offer explanations for why this may be the case. The paper thus identifies 'core' refactorings central to many of the changes made by developers on open-source systems. While we can not guarantee that developers consciously undertake refactoring in any sense, the empirical results demonstrate that simple renaming and moving fields/methods between classes are common components of open-source system re-engineering. From a wider software engineering perspective, knowledge of what a modification will incur in likely sub-tasks is of value to developers whether working on open-source or other forms of software.","2006","2025-04-25 15:27:41","2025-04-25 15:27:41","","288–296","","","","","","","ISESE '06","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Rio de Janeiro, Brazil","","","","code smells; refactoring; taxonomy; testing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Secure kernel can protect user or system data from unauthorized and/or illegal accesses by applying various access control policies like DAC, MAC, RBAC, and so on. But, even if secure operating system is running under various access control policies, network traffic among these secure operating systems can be captured and exposed easily by network monitoring tools like packet sniffer if there is no protection policy for network traffic among secure operating systems. For this reason, protection for data within network traffic is as important as protection for data within local system. In this paper, we propose a secure operating system trusted channel, SOSTC, as a prototype of a simple secure network protocol that can protect network traffic among secure operating systems and can transfer security information of the subject.

The overall success of peer code review, commonly used in open source projects, has likely contributed strongly to this success. Code review is an emotionally loaded practice, with public exposure of reputation and ample opportunities for conflict. We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process. It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market. In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-04-25 15:28:40","2025-04-25 15:28:40","","1073-1083","","","","","","","International Conference on Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE Comp Soc, Tech Comm Software Engn","","","","","","","","","ISSN: 0270-5257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By identifying problems before they arise in production, it enhances the quality of the code. Finding the best reviewer for a code change, however, is extremely challenging especially in large scale, especially open source software stacks with cross functioning designs and collaborations among multiple developers and teams. Additionally, a review by someone who lacks knowledge and understanding of the code can result in high resource consumption and technical errors. The reviewers who have the specialty in both functioning (domain knowledge) and non-functioning areas of a commit are considered as the most qualified reviewer to look over any changes to the code. Quality attributes serve as the connection among the user requirements, delivered function description, software architecture and implementation through put the entire software stack cycle. In this study, we target on auto reviewer assignment in large scale software stacks and aim to build a self-learning, and self-correct platform for intelligently matching between a commit based on its quality attributes and the skills sets of reviewers. To achieve this, quality attributes are classified and abstracted from the commit messages and based on which, the commits are assigned to the reviewers with the capability in reviewing the target commits. We first designed machine learning schemes for abstracting quality attributes based on historical data from the OpenStack repository. Two models are built and trained for automating the classification of the commits based on their quality attributes using the manual labeling of commits and multi-class classifiers. We then positioned the reviewers based on their historical data and the quality attributes characteristics. Finally we selected the recommended reviewer based on the distance between a commit and candidate reviewers. In this paper, we demonstrate how the models can choose the best quality attributes and assign the code review to the most qualified reviewers. With a comparatively small training dataset, the models are able to achieve F-1 scores of 77% and 85.31%, respectively.","2022","2025-04-25 15:28:40","2025-04-25 15:28:40","","","","","","","","","IEEE ACM International Conference on Automated Software Engineering","","","","IEEE; Assoc Comp Machinery; Meta; IBM; Ford; Huawei; Google; IEEE Comp Soc; IEEE Tech Council Software Engn; Special Interest Grp Software Engn; ACM SIGAI; Oakland Univ, Sch Engn & Comp Sci","","","","","","","","","ISSN: 1527-1366","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the impact of such bots on maintenance tasks is still neglected. In this paper, we study how project maintainers experience code review bots. We surveyed 127 maintainers and asked about their expectations and perception of changes incurred by code review bots. Our findings reveal that the most frequent expectations include enhancing the feedback bots provide to developers, reducing the maintenance burden for developers, and enforcing code coverage. While maintainers report that bots satisfied their expectations, they also perceived unexpected effects, such as communication noise and newcomers' dropout. Based on these results, we provide a series of implications for bot developers, as well as insights for future research.","2020","2025-04-25 15:28:40","2025-04-25 15:28:40","","457-462","","","","","","","","","","","Univ Fed Rio Grande Norte; UERN; Loggi; Google; Conselho Nacl Desenvolvimento Cientifico & Tecnologico; Software Engn Team Res & Innovat; Inst Metropole Digital; UFRN, DIMAP","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By 2016 an estimated 95% of all commercial software packages will include OSS components. This pervasive adoption is not without risks for an industry that has experienced significant failures in product quality, timelines and delivery costs. Exhaustive testing of any software system and, specifically, of open source software components is usually not feasible due to limitations in time and resources. In risk-based testing approach test cases are selected and scheduled based on software risk analysis. This research introduces the strategy of risk-based adaptive testing of OSS by combining information on the OSS community ecosystem with risk-driven tests selection and scheduling strategy. A key feature of the proposed approach is the monitoring and analysis of OSS community dynamics, including chats and email communications, blogs, repositories of bugs and fixes, and more. The community and its dynamics are then monitored to detect anomaly communication between the community members. Our approach is demonstrated in the XWiki OSS, a Java-based environment that allows for the storing of structured data and the execution of server side scripts within the wiki interface.

Information, communication and information technology have made developing business becomes very competitive. It is very crucial for companies to have fast and accurate access to mission-critical business information in order to maintain its competitiveness. The ability to establish network connections between the existing systems becomes a must in order to optimize the use of critical information. To realize this, the implementation of system integration looks promising. However, system integration process is not an easy task because it involves variety of systems with different organizations backgrounds. The main objective of this paper is to propose an integration model that is generic and easily adapted by many organizations. The Information Management Division, Public Sector Department in Malaysia is chosen as a case study. The systems used in this department will be analyzed and problems faced will be identified. Research methodology conducted includes the Analysis Phase, Design Phase, Development Phase and Testing Phase. In order to support the proposed model, prototype called myIntegration is implemented based on OpenSyncro. OpenSyncro is an open source software (OSS) meant for Enterprise Application Integration (EAI). The Testing Phase was carried out by taking into account the actual test scenario involving the Department A (owner of the Malaysian Personal Record) and Department B (Human Resources Manager of Malaysian Civil Servants). Tests conducted have shown that the exchange of information between the Department A and B have been successfully realized. The finding from this research, where a new integration model has been created, can be referred by any government or private organizations in developing their systems integration facilities. The model also besides reducing the requirement of hardware; also reduces the dependency to proprietary products. In addition, the prototype developed, which based on OpenSyncro is capable in providing an alternative solution to the IT community to anchor any systems integration project at a lower cost and in a user friendly environment.","2011","2025-04-25 15:28:40","2025-04-25 15:28:40","","13-18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However empirical studies on modularity of OSS systems have resulted in confusing results. To account for underlying mechanisms of those confusing results, we systematically examine widely studied OSS projects. Based on our systematic review on technical and organizational structures, we suggest that organizational circumstances of OSS production are at least in a continuum of tightly-coupled and loosely- coupled organizational circumstances of production in which both geographically distributed volunteers and paid developers with organizational ties work together (albeit separately over time). Furthermore, organizational circumstances of OSS production appear to be dynamic, as firms move in and out of OSS production communities over time. In essence we argue that the reason for the confusing empirical results was a persistent assumption that organizational circumstances of OSS production are static or unitary; rather what matters is the organizational circumstances of production in any episode of contribution. This research agenda paper proposes future inquiries to develop a comprehensive picture of ecological shift in different levels of system modularity and organizational circumstances of OSS production over time and through episodes.","2014","2025-04-25 15:28:40","2025-04-25 15:28:40","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently women represent less than 24% of the computing workforce and that number is declining. On the other hand, the ratios of women in Open Source Software (OSS) projects are even lower. Aims: The primary objective of this study is to determine the level of gender diversity among popular OSS projects and identify the presence of gender biases that may discourage females' participation. Method: On this goal, we mined the code review repositories of ten popular OSS projects. We used a semi-automated approach followed by a manual validation to identify the genders of the active contributors. Results: Our results suggest that lack of gender diversity remains an ongoing issue among all the ten projects as each of the projects had less than 10% female developers. However, many of the projects also suffer from lack of inclusion of females to leadership positions. Although none of the projects suggest significant differences between male and female developers in terms of productivity based on three different measures, data from three out of the ten projects indicate technical biases against female developers with lower code acceptance rates as well as delayed feedback during code reviews. However, biases against females are not universal as majority of the projects do not discriminate against females. The two projects with the least ratios of female contributors as core developers showed the most biases against females. Conclusion: Based on our findings, we conclude that promoting and mentoring females to leadership positions may be an effective solution to foster gender diversity.","2019","2025-04-25 15:28:40","2025-04-25 15:28:40","","295-305","","","","","","","International Symposium on Empirical Software Engineering and Measurement","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; Brazilian Comp Soc; CESAR Sch; State Pernambuco Fdn Sci & Technol; Natl Council Sci & Technol Dev, Brazilian Minist Sci, Technol, Innovat, & Commun","","","","","","","","","ISSN: 1938-6451","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In our study, we broadly investigate whether and how these quality assurance approaches are being used in conjunction in the development of 1454 popular open source software projects on GitHub. Our study indicates that typically projects do not follow all quality assurance practices together with high intensity. In fact, we only observe weak correlation among some quality assurance practices. In general, our study provides a deeper understanding of how existing quality assurance approaches are currently being used in Java-based open source software development. Besides, we specifically zoom in on the more mature projects in our dataset, and generally we observe that more mature projects are more intense in their application of the quality assurance practices, with more focus on their ASAT usage, and code reviewing, but no strong change in their CI usage.","2024-08","2025-04-25 15:28:41","2025-04-25 15:28:41","","1408-1446","","8","54","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 15:28:41","2025-04-25 15:28:41","","194-244","","","49","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Usability is a clear concept that encompassing both task and user characteristics as well as functionality. Usability is an essential factor that affects user acceptance and OSS sustainability, which is considered as the key to the success of the OSS. To some extent, usability is one concern of the larger issue of system acceptability and sustainability. Therefore, usability is an important factor that needs to be considered since the software that is not usable is not going to be sustainable. The objective of this paper is to review researchers' efforts to improve, investigate, and evaluate the usability factor that may affect the OSS acceptability and sustainability and map the research scenery from the articles into a comprehensible structured taxonomy, which would help the researchers to identify different research gaps of this field. A survey of the usability in OSS conducted and 6033 studies identified by a search in four scholarly databases using a query that includes the keywords (usability or learnability or efficiency or satisfaction) and (open source software or OSS). A total of 46 studies are selected. By manually searching in ACM, Springer, and Google Scholar five other studies identified, and thus a total of 51 studies were the final set that includes in this paper. Based on research topics, a taxonomy created and divided into four principal categories which improve OSS usability, analyze OSS usability, evaluate OSS usability, and select and adopt OSS. A comprehensive overview and synthesis of these categories are presented as well. This paper contributes to identifying the possible opportunities and gaps for enabling the participation of interested researchers in this research area. And give possibilities for extending the use of usability research and practices to create more sustainable software. Also, helps in selecting suitable OSS among the alternatives.","2019","2025-04-25 15:28:41","2025-04-25 15:28:41","","65913-65933","","","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Only a small percentage of SA organisations have significant usage levels of OSS, with the majority of OSS users planning on maintaining their current levels of usage. It was observed that 67% of non-OSS users are considering OSS use in the future, with the majority of these respondents having made preliminary investigations into the viability of OSS use. Further results show an association between the size of an organisation and the usage of OSS, with smaller and medium sized enterprises using OSS more than larger organisations. It was also observed that the majority of training institutes perceive that there will be a growth in demand for OSS training within the next 5 years, which correlates with findings that the number of training workshops and institutes are increasing to accommodate the increase in demand.","2006","2025-04-25 15:28:41","2025-04-25 15:28:41","","1404-1419","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our results indicate that FOSS project members possess rather sophisticated notions of software usability, which collectively mirror definitions commonly found in HCI textbooks. Our study also uncovered a wide range of practices that ultimately work to improve software usability. Importantly, these activities are typically based on close, direct interpersonal relationships between developers and their core users, a group of users who closely follow the project and provide high quality, respected feedback. These relationships, along with positive feedback from other users, generate social rewards that serve as the primary motivations for attending to usability issues on a day-to-day basis. These findings suggest a need to reconceptualize HCI methods to better fit this culture of practice and its corresponding value system.","2010","2025-04-25 15:28:41","2025-04-25 15:28:41","","999-1008","","","","","","","","","","","Google; Microsoft; NSF; Yahoo Labs; ACM SIGCHI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then, European universities have been involved in the development of the so-called European Higher Education Area (EHEA), including the adoption of a system of easily readable and comparable degrees, the European co-operation in quality assurance, and the promotion of mobility and European dimension in higher education. In this framework, the use of Free Open Source Software (FOSS) could provide several advantages, related to both the freedom given to users and the strengths of its peer-to-peer development model. In fact, some of the most outstanding characteristics of the FOSS (free, democratic, sustainable and technologically competitive educational model, cooperative and competitive relationships,.) result to be coincident with the main aims of the European Higher Education Area. In this paper we describe the role that this Free Open Source Software could play in the University context, also providing some statistical evidence about FOSS penetration and its recent evolution. Furthermore, since the implementation of the new university degrees can be considered as a “break point”, we briefly describe our FOSS experiences at the University of Oviedo, involving Statistics and Econometrics.

However, the existing literature implicitly takes a static view that software structure and organizational structure are established early on and change slowly over time, if at all. Such a view does not fully reflect the complex and dynamic nature of software development and tends to overlook the role played by human agents as they ramp involvement up and down over time. This study considers that coordination practice plays an important role in altering technical interdependencies in OSS development. This study investigates coordination practices that result in changes in software coupling-in particular, increases in software coupling. This study automatically analyzes the code in 72 software releases and 1033 task episodes of three successful OSS projects-GNU grep, IPython, and Scikit-image. This study takes a fine-grained practice-oriented perspective that views the way that the work is done as constituting the organization. In our conceptualization, OSS contributors use a configuration of multiple organizational elements, enacted and varying across specific episodes of practice. In line with this perspective, this study takes a configurational approach, uses fuzzy-set qualitative comparative analysis (fsQCA) to analyze episodes that led to decreases, no changes, and increases in software coupling during the inter-release periods in which the level of software coupling increased significantly, which we call focal period. We find that co-work involving multiple individuals tends to result in code that adds technical dependencies (increases in software coupling) during the focal period. To illustrate this beyond our fuzzy-set analysis, we present and discuss three episodes in narrative detail. The fine-grained, configurational analysis in this study supports the idea that the organizing process is ongoing enactment. In this study, OSS systems are an amalgam of code that builds up in different episodes each possibly different organizational configurations, rather than thinking of the OSS systems or projects as static or singular.","2024-03","2025-04-25 15:28:41","2025-04-25 15:28:41","","","","1","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A good understanding of how developers work together could positively impact software development practices. In this paper, we investigate the collaboration habits of developers in project files by leveraging the World of Code (WoC) dataset and GitHub API. We first identify the collaboration level of developers within the project files, such as the source, test, documentation, and build files, using the Author Cross Entropy (ACE). From the results we find out that test files report the highest degree of collaboration among the developers, perhaps because collaboration is critical to ensure convergence of functionality tests. Furthermore, the source code files show the least degree of collaboration, perhaps because of code ownership and the complexity and difficulty in code modification. Secondly, given the widespread usage of the Python programming language, we investigate the Python code tokens that are more prone to change and collaboration. Our findings offer insights into the specific project files and Python code tokens that developers typically collaborate on in the opensource community. This information can be used by researchers and developers to enhance existing collaboration platforms and tools.","2023","2025-04-25 15:28:42","2025-04-25 15:28:42","","352-356","","","","","","","IEEE International Working Conference on Mining Software Repositories","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; GitHub; Huawei Canada","","","","","","","","","ISSN: 2160-1852","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An Examination of Open-Source Software Development by Organizations and Individuals","INFORMATION SYSTEMS RESEARCH","","1047-7047","10.1287/isre.2018.0829","","Collaboration through open superposition describes the dominant work orchestration mechanism observed in free (Libre) and open-source (FLOSS) software, wherein the software development occurs by the sequential layering of individual tasks. This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 15:28:42","2025-04-25 15:28:42","","764-786","","3","30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, ungoverned use of FLOSS components can result in legal and financial risks, and risks to a firm's intellectual property. To avoid these risks, companies must govern their FLOSS use through open source governance processes and by following industry best practices. A particular challenge is license compliance. To manage the complexity of governance and compliance, companies should use tools and well-defined processes. This paper investigates and presents industry requirements for FLOSS governance tools, followed by an evaluation of the suggested requirements. We chose eleven companies with an advanced understanding of open source governance and interviewed their FLOSS governance experts to derive a theory of industry requirements for tooling. We extended our previous work adding the requirement category on the architecture model for software products. We then analyzed the features of leading governance tools and used this analysis to evaluate two categories of our theory: FLOSS license scanning and FLOSS components in product bills of materials. The result is a list of FLOSS governance requirements. For practical relevance, we cast our theory as a requirements specification for FLOSS governance tools. (C) 2019 Elsevier Inc.

To propose a model for the acceptance of OSS; investigate the influence of the OSS characteristics, UTAUT constructs, and infrastructure factors on the acceptance of open source software system. It also examines the validity of UTAUT in the open source software context. Quantitative design has been used following the distribution of questionnaire among a sample of 255 individuals employed at public and private organizations (172 males and 83 females). Software quality, software interoperability, and software security had a significant impact on the performance expectancy (PE) (beta = 0.445, P < 0.001), (beta = 0.302, P < 0.001), (beta = 0.139, P < 0.05), respectively. Moreover, PE, cost, facilitating conditions, social influence SI and self-efficacy had a notable impact on the behavioral intention (beta = 0.275, P < 0.05), (beta = 0.229, P < 0.01), (beta = 0.136, P < 0.01), (beta = 0.220, P < 0.01) and (beta = 0.174, P < 0.01) respectively.

For example, toxic code review comments may raise pushback from an author to complete suggested changes. A toxic communication with another person may hamper future communication and collaboration. Research also suggests that toxicity disproportionately impacts newcomers, women, and other participants from marginalized groups. Therefore, toxicity is a barrier to promote diversity, equity, and inclusion. Since the occurrence of toxic communications is not uncommon among FOSS communities and such communications may have serious repercussions, the primary objective of my proposed dissertation is to automatically identify and mitigate toxicity during developers' textual interactions.

The projects and developers co-evolve in an ecosystem. To keep healthy evolution of such OSS ecosystems, there is a need of attracting and retaining developers, particularly project leaders and core developers who have major impact on the project and the whole team. Therefore, it is important to figure out the factors that influence developers' chance to evolve into project leaders and core developers. To identify such factors, we conducted a case study on the GNOME ecosystem. First, we collected indicators reflecting developers' subjective willingness to contribute to the project and the project environment that they stay in. Second, we calculated such indicators based on the GNOME dataset. Then, we fitted logistic regression models by taking as independent variables the resulting indicators after eliminating the most collinear ones, and taking as a dependent variable the future developer role (the core developer or project leader). The results showed that part of such indicators (e.g., the total number of projects that a developer joined) of subjective willingness and project environment significantly influenced the developers' chance to evolve into core developers and project leaders. With different validation methods, our obtained model performs well on predicting developmental core developers, resulting in stable prediction performance (0.770, F-value).","2017-03","2025-04-25 15:28:42","2025-04-25 15:28:42","","396-414","","2","32","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this study is to explore the status quo of educational application of FOSS and the trends from international perspectives and its implications for higher education in Hong Kong. Design/methodology/approach The method of cluster analysis was used in this study. The Web of Science database was used as the data source and all relevant literature for the year 2010-2020 on the theme of “FOSS” was collected for analysis. The information visualization software CiteSpace was used for citation visualization analysis, revealing the research results of FOSS worldwide, including hot spots and development trends. Findings This paper found that FOSS has become an important research area and is playing an important role in the reform and development of education. Meanwhile, the development and application of FOSS have regional imbalances and strong differentiation, including the educational sector. The paper also found that although FOSS has entered the stage of interdisciplinary development, the research and development of FOSS in the field of education is insufficient, which poses a huge challenge to decision-makers, teachers and students. Originality/value Implications for higher education in Hong Kong including: attach importance to and vigorously promote FOSS research and practice to benefit more teachers and students; teachers and students need to be trained for acquiring the awareness and skills of FOSS applications and formulate different strategies; the government should provide greater support to formulate and implement a short and middle-term development plan to facilitate the application of FOSS; and Hong Kong higher education institutions may strengthen exchanges and cooperation with counterparts around the world to jointly promote the development of FOSS.

OSS influences the way organizations develop, acquire, use and commercialize software. SECOs have emerged as a paradigm to understand dynamics and heterogeneity in collaborative software development. For this reason, SECOs appear as a valid instrument to analyze OSS systems. However, there are few studies that blend both topics together. Objective: The purpose of this study is to evaluate the current state of the art in OSS ecosystems (OS-SECOs) research, specifically: (a) what the most relevant definitions related to OSSECOs are; (b) what the particularities of this type of SECO are; and (c) how the knowledge about OSSECO is represented. Method: We conducted a systematic mapping following recommended practices. We applied automatic and manual searches on different sources and used a rigorous method to elicit the keywords from the research questions and selection criteria to retrieve the final papers. As a result, 82 papers were selected and evaluated. Threats to validity were identified and mitigated whenever possible. Results: The analysis allowed us to answer the research questions. Most notably, we did the following: (a) identified 64 terms related to the OSSECO and arranged them into a taxonomy; (b) built a genealogical tree to understand the genesis of the OSSECO term from related definitions; (c) analyzed the available definitions of SECO in the context of OSS; and (d) classified the existing modelling and analysis techniques of OSSECOs. Conclusion: As a summary of the systematic mapping, we conclude that existing research on several topics related to OSSECOs is still scarce (e.g., modelling and analysis techniques, quality models, standard definitions, etc.). This situation calls for further investigation efforts on how organizations and OSS communities actually understand OSSECOs. (C) 2017 Elsevier B.V.

Prior studies of open source governance have largely focused on its changing nature over time. In this work, we argue that the nature of governance varies across open source communities, and, in its evolution, multiple traces of authority may co-exist. We propose that such multiplicity can be understood by close examination of the authoritative structures embedded in coordination processes. We collected eight years of data on the coordination related to version control of the Linux kernel. Drawing on in-depth qualitative analysis, we investigate how coordination processes with different authoritative structures come together in the governance of open source software. We trace four coordination processes (autocratic clearing, oligarchic recursion, federated self-governance, and meritocratic idea-testing), each grounded in different authoritative structures (autocracy, oligarchy, federation, meritocracy) with their own form of legitimation. We offer a two-fold contribution in this paper. First, we enhance the open source governance literature by advancing a new theoretical perspective in which governance is seen as a configuration of coordination processes. Configurations give complementary support and are a source of tension and renewal. Second, we articulate a view on the conceptual relationship between governance and coordination where these concepts are understood as a duality, both working together to give rise to efficient and dynamic organizing in open source.","2017-06","2025-04-25 15:28:42","2025-04-25 15:28:42","","116-135","","2","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While natural ecosystems have been the subject of study for many decades, research on software ecosystems is more recent. For this reason, the ECOS research project aims to determine whether and how selected ecological models and theories from natural ecosystems can be adapted and adopted to understand and better explain how OSS projects (akin to biological species) evolve, and to determine what are the main factors that drive the success or popularity of these projects. Expressed in biological terms, we wish to use knowledge on the evolution of natural ecosystems to provide support aiming to optimize the fitness of OSS projects, and to increase the resistance and resilience of OSS ecosystems.","2014","2025-04-25 15:28:43","2025-04-25 15:28:43","","403-406","","","","","","","","","","","IEEE; IEEE Comp Soc; Tech Council Software Engn; Fnrs; FWO; Univ Antwerpen; Reengineering Forum","","","","","","","","","","","","","","","Demeyer, S; Binkley, D; Ricca, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For instance, open source software (OSS) is developed by mass collaboration on digital communities to provide software users free alternatives to commercial products. OSS is particularly valuable to meet the needs of numerous disadvantaged users for whom proprietary software is not affordable. While OSS projects are lack of formal organizational structure, project leaders play a significant role in initiating and managing these projects and eventually, influencing the degree to which the developed software is used and liked by users. Drawing on resource dependence theory, we investigate the impacts of two team-level characteristics of OSS project leaders (ie, size and tenure) on how well the developed software can address users' needs, with regard to the quantity of software being used by users and the quality of software to users' satisfaction. Further, from a resource dependence perspective, we examine the moderating role of project leaders' network ties in shaping the contingency of these effects. By using a large-scale dataset from 43 048 OSS development projects in SourceForge community, we find empirical evidence corroborating our theory. Taken together, our findings suggest the boundary-spanning role of project leaders in developing digital social innovation.","2021-09","2025-04-25 15:28:43","2025-04-25 15:28:43","","672-694","","5, SI","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, deciding a proper OSS to be adopted or to contribute to its development is a complex and error-prone task. Analyzing the OSS ecosystem (OSSECO) health may help providing information about: (1) the OSS itself (number of commits, days after the last release, etc.); and (2) their main actors (number of contributors, partners, etc.). There exist proposals that go further and provide aggregated high-level indicators (e.g. visibility as an aggregation of number of community events, number of partners, and other metrics). Nevertheless, there is a lack of useful OSSECO analysis tools to ease the decision making on which OSSECO has the health required by a potential OSS adopter or contributor. In this work, we provide OSS-CARE (OSSeCo heAlthy monitoR and analysEr), an OSS-independent, fully automatic, and real-time framework to assess OSSECO's health. OSS-CARE supports defining the ecosystem health objectives of potential OSS adopters, OSS contributors, and even OSS managers to inspect their provided health. These objectives are defined based on a well-established model characterizing health metrics that can be potentially aggregated by using a Bayesian network technique. Moreover, the integrated monitoring and analysis components perform an automated assessment of OSSECO's health by checking the fulfillment of the required health objectives. Furthermore, the result is shown in an appealing dashboard that may ease the complex decision making of which OSS to choose.","2023-07","2025-04-25 15:28:43","2025-04-25 15:28:43","","","","","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Over time, organizations face the OSS adoption challenge strengthening mainly its internal and technical elements. However, the rapid changes on business dynamics, and the comprehensiveness and fast development of open paradigms, show us that a new set of conditions must be satisfied to reach a successfully OSS adoption. These conditions, considered as a critical success factors, involve a wide range of resources, capacities and skills, both in internal and external scopes. Hence, although adopter organizations should be better prepared to face the challenges related to collaborative innovation, they do not have a systematic approach to value its readiness level to face the adoption challenges. In this context, the present research work proposes a model to assess the organizational readiness, considering the adopter as part of a live business ecosystem, where the relationships originated on co-development with developers' communities, have mutual business impact at strategic, tactic, and operative level.","2021","2025-04-25 15:28:43","2025-04-25 15:28:43","","800-807","","","","","","","","","","","INSTICC","","","","","","","","","","","","","","","Filipe, J; Smialek, M; Brodsky, A; Hammoudi, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of OSS does not harm security; on the contrary, it enhances it. Even with some drawbacks, OSS is highly reliable and maintained by a huge software community, thus decreasing implementation costs and increasing reliability. Moreover, it allows military software engineers to move away from proprietary applications and single-vendor contracts. Furthermore, it decreases the cost of long-term development and lifecycle management, besides avoiding vendor's lock in. Nevertheless, deploying OSS deserves an appropriate organization of its life cycle and maintenance, which has a relevant impact on the project's budget that cannot be overseen. In this paper, we will describe some of the major trends in OSS in Defense environments. The community for OSS has a pivotal role, since it is the core development unit. With Agile and the newest DevOps methodologies, government officials could leverage OSS capabilities, decreasing the Design (or Technical) Debt. Software for Defense purposes could perform better, increase the number of the releases, enhance coordination through the different IT Departments (and the community), and increase release automation, decreasing the probability of errors.","2016","2025-04-25 15:28:43","2025-04-25 15:28:43","","123-131","","","422","","","","Advances in Intelligent Systems and Computing","","","","","","","","","","","","","ISSN: 2194-5357","","","","","","Ciancarini, P; Sillitti, A; Succi, G; Messina, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Substantial research was done to investigate central projects such as Linux kernel but we have only a limited understanding of how the periphery of the larger OSS ecosystem is interconnected through technical dependencies, code sharing, and knowledge flows. We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-25 15:28:43","2025-04-25 15:28:43","","3","","","","","","","","","","","Assoc Comp Machinery; Assoc Comp Machinery Special Interest Grp Software Engn","","","","","","","","","","","","","","","Dumas, M; Pfahl, D; Apel, S; Russo, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Built-in support to quantitative analysis and machine learning tasks based on the quantitative evolutionary events are provided.

OSS is written collaboratively with the process and products publically observable, whereas the original laws were derived based on a very different context. The question then arises if Lehman's laws apply to modern day OSS software. The GitHub repository is the most comprehensive source of OSS projects and is used here to obtain data on how OSS projects have evolved. This work uses one hundred open source projects hosted on GitHub. Metrics are obtained via the provided API, using a purpose-built workbench and several of Lehman's laws are evaluated using the data available. Coupled with a critique of how judgements can be made from the data available, the study has discovered that the evidence does not support many of the laws. An important proviso with such an approach is the limitation on what data can be extracted and/or inferred from the GitHub API.

Therefore, adapting theories and statistical models of natural language evolution to code is expected to provide unique insights into software evolution. Our analysis in this paper is conducted using 2,000 OSS systems sampled from a broad range of application domains. Our results show that a) OSS projects exhibit a significant shift in their linguistic identity over time, b) different syntactic structures of code lexicon evolve differently, c) different factors of OSS development and different maintenance activities impact code lexicon differently. These insights lay out a preliminary foundation for modeling the linguistic history of OSS projects. In the long run, this foundation will be utilized to provide support for basic software maintenance and program comprehension activities, and gain new theoretical insights into the complex interplay between linguistic change and various system and human aspects of OSS development.","2019","2025-04-25 15:28:43","2025-04-25 15:28:43","","296-300","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lockin, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-04-25 15:28:44","2025-04-25 15:28:44","","7-12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there are numerous issues associated with OSS, including its influence on the total cost of ownership (TCO) and supportability and upgradeability risks. While savings from obtaining a free copy of the software can be significant, software accounts for an average of 10% of TCO, while the majority of the costs are associated with project staffing. OSS requires significant investment into staffing because it needs to be carefully selected, customized, and installed. In addition, global communities may gather and dissolve at their will, so guarantees of support, revision, and bug fixes are minimal. Yet companies can gain competitive advantage through an ability to customize software to address specific business issues and exercising control over development, revision schedules, and modifications. OSS is not a panacea from the rising software costs. Instead, it is a serious initiative that has benefits, disadvantages, and risks associated with it.","2007","2025-04-25 15:28:44","2025-04-25 15:28:44","","277-282","","","234","","","","INTERNATIONAL FEDERATION FOR INFORMATION PROCESSING","","","","IFIP WG2 13","","","","","","","","","ISSN: 1571-5736","","","","","","Feller, J; Fitzgerald, B; Scacchi, W; Sillitti, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A variety of open-source software ecosystems have emerged, for instance, GitHub, StackOverflow, and SourceForge. One of the most typical social-programming and code-hosting sites, GitHub, has amassed numerous open-source-software projects and developers in the same virtual collaboration platform. Since GitHub itself is a large open-source community, it hosts a collection of software projects that are developed together and coevolve. The great challenge here is how to identify the relationship between these projects, i.e., project relevance. Software-ecosystem identification is the basis of other studies in the ecosystem. Therefore, how to extract useful information in GitHub and identify software ecosystems is particularly important, and it is also a research area in symmetry. In this paper, a Topic-based Project Knowledge Metrics Framework (TPKMF) is proposed. By collecting the multisource dataset of an open-source ecosystem, project-relevance analysis of the open-source software is carried out on the basis of software-ecosystem identification. Then, we used our Spectral Clustering algorithm based on Core Project (CP-SC) to identify software-ecosystem projects and further identify software ecosystems. We verified that most software ecosystems usually contain a core software project, and most other projects are associated with it. Furthermore, we analyzed the characteristics of the ecosystem, and we also found that interactive information has greater impact on project relevance. Finally, we summarize the Topic-based Project Knowledge Metrics Framework.","2019-02","2025-04-25 15:28:44","2025-04-25 15:28:44","","","","2","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS has transformed how software is developed, distributed, and maintained. This increase in popularity has led to extensive research in various domains of OSS, such as evolution, adoption, community and development processes.With the passage of time the volume of academic studies increased in the area of OSS, including Systematic Literature Reviews (SLRs) and Systematic Mapping Studies (SMS), which have provided valuable insights into specific aspects of OSS. The OSS domain is vast, with many areas that are still under explored. The fragmented nature of the existing studies presents challenges for both researchers and practitioners in identifying comprehensive research trends, gaps, future directions, and the cohesive understanding of the broader trends within the field. The secondary studies synthesize the literature to highlight findings and gaps of an area. The fragmentation of OSS academic literature limits the ability of researchers to identify unexplored or under-researched areas. This also creates challenges for both practitioners and researchers, as they lack awareness of the best practices, tools, technologies, and methodologies in a OSS domain. This study is motivated by the need to consolidate the extensive research conducted in the OSS domain, providing a holistic view that can guide future investigations and practical applications. The rationale for conducting this research lies in the opportunity to aggregate and classify existing OSS research areas, topics, and future directions through a systematic tertiary study. By synthesizing the findings from secondary studies, this research aims to offer a meta-level understanding of the OSS field, uncovering overlooked areas and defining a research agenda. The systematic approach, guided by the established protocol of Kitchenham, ensures that the study is conducted rigorously, with a focus on comprehensiveness and reliability. Ultimately, this research seeks to contribute to the OSS community by highlighting key research areas that require further exploration, thereby advancing the field and supporting the continued growth and innovation within OSS development. A systematic tertiary study is performed to cover all the systematic secondary studies in the area of OSS. The guidelines of Kitchenham are used for designing the protocol. The protocol details the research objectives, scope, search strategy, data extraction, quality assessment and synthesis. The protocol is detailed in section three for transparency. We have identified seventy-four studies that consist of twenty-five SMS and forty-nine SLR. The literature is mapped to a published taxonomy of OSS by Aksulu and Wade, however, the future directions are thematically analyzed. The results of mapping show that the highest number of studies (forty-seven) are in the sub-category of “OSS categorization/research agenda”, whereas eight studies are mapped to the subcategory “OSS vs Proprietary”. Both of these sub-categories fall in the main category of “Conceptual”. The second major work is in the “OSS Production” category in the sub-categories of “Communities” (ten), “Process” (eight), “User and Developer Motivation” (nine), and “Self-Organization (Product and Community Evolution)” (six). Seven studies are also mapped to the sub-category of “Software Quality” in the main category of “Performance Metrics”. Other categories have fewer studies mapped to them. The areas identified, thematically, for future directions are “OSS contributors”, “OSS development process”, “OSS evolution and prediction”, “use of OSS in different domains”, and “OSS adoption/adaptation/integration”. The mapping between “key research areas” of systematic secondary studies and “taxonomy categories” shows that there is no or little research in some of the categories of taxonomy, having potential of future research. The future directions thematic analysis will also aid researchers and practitioners.","2024","2025-04-25 15:28:44","2025-04-25 15:28:44","","189952-189993","","","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Power relations are present in this context whenever an entity has the power of making other entities act as it wants them to act. Therefore, these power relations could affect collaboration within an OSSECO. Objective: This research aims at investigating power relations, their benefits and challenges, and providing an understanding of them within OSSECO. The goal is to provide power relations forms description together with the power relations dynamics associated with them. Method: A systematic mapping study was conducted to extract information about power relations (forms, dynamics, benefits, and challenges) from previous studies. At the end, 10 studies reporting power relations within OSSECO were selected. Next, the data extracted from those was analyzed to understand what power relations affect the OSSECO and how this happens. Based on the results, the power relation forms and dynamics within OSSECO are defined. Results: The systematic mapping study show that power relations are present and affect relationships and interactions within an OSSECO. Moreover, 5 power relations forms and 7 power relations dynamics within OSSECO are presented. Implications: Identifying power relations that might be present within an OSSECO would enable those who study or are members of the ecosystem's community to enhance power relations that support collaboration and to avoid those who can lead developers to leave the OSSECO.","2021","2025-04-25 15:28:44","2025-04-25 15:28:44","","187-193","","","434","","","","Lecture Notes in Business Information Processing","","","","Univ Oslo, Dept Informat","","","","","","","","","ISSN: 1865-1348","","","","","","Wang, X; Martini, A; NguyenDuc, A; Stray, V","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software managers and developers use several measures to measure and improve the quality of a software solution throughout the development process. These measures assess the quality of different software attributes, such as product size, cohesion, coupling, and complexity. Researchers and practitioners use software metrics to understand and improve software solutions and the processes used to develop them. Determining the relationship between software metrics aids in clarifying practical issues with regard to the relationship between the quality of internal and external software attributes. We conducted an empirical study on two open source systems (JEDIT and ANT) to study the defectiveness Evolution in Open Source Software Systems. The result reveals that a good designed software has lesser defects and have high cohesion. Moreover the study also revealed that defects are higher in initial versions and most corrected errors are from major classes in initial version. Removal of defects also reveals that a good software is consistently improved and feed backs are important part of open source systems. (C) 2016 The Authors.

Research in the area of customization of OSS is rare, however. The process after the deployment of an OSS within a company remains unknown. There is a danger that it is often unstructured and error-prone since OSS develops in a more complex way than proprietary software. Based on our literature study, modifications of open source code do occur also in organizations outside of the software industry. Customization of applications is more common than customization of infrastructure software in these organizations. Therefore, we examine the process of deployment and adaptation of an OSS application software over several update iterations in great detail. This examination shows that this process has similarities with the process of deployment of proprietary software but it also exhibits important differences. Based on this case study, we also suggest a process model for customization of OSS applications in user organizations.","2009","2025-04-25 15:28:44","2025-04-25 15:28:44","","129-142","","","299","","","","International Federation for Information Processing","","","","IFIP WG 2 13","","","","","","","","","ISSN: 1571-5736","","","","","","Boldyreff, C; Crowston, K; Lundell, B; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hence, an investigation is necessary to analyze the impact open community dynamics and the quality of the OSS, such as the level and trends in internal communications and content distribution. The analysis results provide inputs to drive selective testing for effective validation and verification of OSS components. The paper suggests an approach for monitoring community dynamics continuously, including communications like email and blogs, and repositories of bugs and fixes. Detection of patterns in the monitored behavior such as changes in traffic levels within and across clusters can be used in turn to drive testing efforts. Our proposal is demonstrated in the case of the XWiki OSS, a Java-based environment that allows for the storing of structured data and the execution of server side scripts within the wiki interface. We illustrate our concepts, methods and approach behind this approach for risk based testing of OSS.","2014","2025-04-25 15:28:44","2025-04-25 15:28:44","","309-321","","","8803","","","","Lecture Notes in Computer Science","","","","","","","","","","","","","ISSN: 0302-9743","","","","","","Margaria, T; Steffen, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we argue that fit between the individual's task, values and work demands can influence or hinder the sustained use of OSS. We explore how task-technology fit and two dimensions of person-organization fit (value-based fit and demand-ability fit) interact with each other to influence productivity performance. Using survey data, we find that congruence between the organization's OSS values and the individual user's OSS values (value-based fit), decreases productivity performance, whereas, fit between an individual's OSS skills and the organizational task demands (demandability fit), increases productivity performance.

-"J48HA5S6","journalArticle","2001","McGowan, D","Legal implications of open-source software","UNIVERSITY OF ILLINOIS LAW REVIEW","","0276-9948","","","The proliferation of computer technology and the advent of the Internet have created many new relationships and problems that raise questions about traditional legal and economic principles. The development of “open-source” or “free” software is an example of this phenomenon. Unlike the traditional producers of computer software - Microsoft for example - open-source software is often developed by computer programmers from all over the world, each submitting contributions to the code, and distributed without charge or for a minimal fee. Open-source software is generally passed from programmer to programmer, with the understanding that improvements may be made, but that the improvements must be distributed freely, without any attempt to “privatize” the program. The existence of such relationships among programmers raise several interesting questions. First, how do large-scale open-source projects come into being? One open-source project, the GNU/Linux operating system, even threatens the market share of Microsoft's operating systems - a feat that calls traditional economic theories on the operation of the firm into question. A more important question is whether the open-source model is sustainable and generalizable. Ultimately, one wonders what role the law will play in the open-source community - a community that seems to operate in the absence of traditional legal principles. In this article, which was introduced at the University of Illinois College of Law Symposium on Intellectual Property Challenges in the Next Century, Professor McGowan addresses these questions. Using the GNU/Linux operating system as a case study, he probes the organization of the open-source community and the philosophies of its leading members in order to understand how traditional firm models, intellectual property, and contract law might apply. Professor McCowan concludes by reviewing recent attempts by courts to impose traditional principles in computer software transaction disputes. Ultimately, it appears that the open-source community cannot be neatly categorized. Although many traditional firm theories - such as the formation of a hierarchy - and legal principles - such as copyright - do apply to the open-source model, these theories and principles are employed in creative ways not previously envisioned.","2001","2025-04-25 15:28:45","2025-04-25 15:28:45","","241-304","","1","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These attributes make OSS an enticing technological choice for a company. Unfortunately, because most enterprises view technology as a proprietary differentiating element of their operation, little is known about the extent of OSS adoption in industry and the key drivers behind adoption decisions. In this article we examine factors and behaviors associated with the adoption of OSS and provide empirical findings through data gathered from the US Fortune-1000 companies. The data come from each company's web browsing and serving activities, gathered by sifting through more than 278 million web server log records and analyzing the results of thousands of network probes. We show that the adoption of OSS in large US companies is significant and is increasing over time through a low-churn transition, advancing from applications to platforms. Its adoption is a pragmatic decision influenced by network effects. It is likelier in larger organizations and those with many less productive employees, and is associated with IT and knowledge-intensive work and operating efficiencies. (C) 2011 Elsevier Inc.

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers' positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-07","2025-04-25 15:28:45","2025-04-25 15:28:45","","","","4","32","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

National user groups can bolster these international communities by convening local events, championing the software to peers, welcoming and onboarding new contributors, raising money to support the broader community, and collecting important information on user's needs. The open source community-led software DSpace has had great success encouraging the creation of national user groups; in the UK, North America, and Germany, the Groups have been active for many years. However, it was in 2018, thanks to a renewed focus on international engagement and more diverse representation of the global community in governance groups, that the national communities entered into a new phase: 15 new national User Groups have been formed all over the world since then, while the German user group evolved into the “DSpace-Konsortium Deutschland”, founded by 25 institutions, marking a pivotal point for membership options and National User Group participation within DSpace Governance. This article will offer an overview of the historical development of the DSpace community and its governance model, as well as DuraSpace's international engagement strategy, including its benefits and challenges.

This paper analyzes the governance of these organizations from the perspective of their structure and control, considering the development trajectory of three communitybased free software projects in Brazil. Results show that the constant need to produce modern technologies gives rise to external pressures that promote change - albeit temporary - in the governance of these projects, making them resemble a cathedral more than a bazaar. Governance does not follow a cycle of sequential improvement; it changes depending on the external organizational actors present, such as sponsors. This suggests the need for strategic and flexible governance to deal with the acquisition and allocation of organizational resources. Governance of the projects described here varies along a spectrum of (in)formality that allows both production models - cathedral or bazaar - to exist in the same organization at different periods.","2022-02","2025-04-25 15:28:45","2025-04-25 15:28:45","","","","1","62","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent studies identified a variety of community smells and defined them as sub-optimal patterns connected to organizational-social structures in the software development community. To early detect and discover existence of potential community smells in a software project, we introduce, in this paper, a novel machine learning-based detection approach, named CSDETECTOR, that learns from various existing bad community development practices to provide automated support in detecting such community smells. In particular, our approach learns from a set of organizational-social symptoms that characterize the existence of potential instances of community smells in a software project. We built a detection model using Decision Tree by adopting the C4.5 classifier to identify eight commonly occurring community smells in software projects. To evaluate the performance of our approach, we conduct an empirical study on a benchmark of 74 open source projects from Github. Our statistical results show a high performance of CSDETECTOR, achieving an average accuracy of 96% and AUC of 0.94. Moreover, our results indicate that the CSDETECTOR outperforms two recent state-of-the-art techniques in terms of detection accuracy. Finally, we investigate the most influential community-related metrics to identify each community smell type. We found that the number of commits and developers per time zone, the number of developers per community, and the social network betweenness and closeness centrality are the most influential community characteristics.

Studying changes to the various characteristics of source code can help us understand the evolution of a software system. In this paper, the software evolution process is analyzed using a proposed Evolution curve (E-curve) method, which is based on information theoretic metrics of source code.

One of them is maintainability, which in turn is made up of measurable attributes. Previous studies have shown that documentation, by contributing to the comprehensibility of software, may have a positive effect on maintainability and, hence, software quality. This paper presents a study in which we analyzed Javadoc comments from 163 different open-source projects. Javadoc is the de facto standard for documenting source code files in Java projects, and although its syntax is less strict than in other (programming) languages, documentation written with Javadoc may contain violations. Our study focuses on the detection of different types of Javadoc violations as well as the source code elements affected by them. Also, by utilizing software repository mining techniques, we examined the history of the subject systems to gain further insights into the evolution of Javadoc violations. According to our results, about half of the source code elements have no Javadoc whatsoever. Among the different components of Javadoc comments (if present), the description of exceptions, by far, has the highest average ratio of violations. With regard to the types of affected elements, constructors and methods show very high average ratios. Also, we found that, on average, violations live more than two years. Nowadays, most integrated development environments (IDEs) for Java are capable of detecting missing Javadoc comments as well as comments with syntactic errors. However, our results indicate that the documentation of source code might be considered less important to developers or that these tools alone may not be sufficient for maintaining consistent documentation.","2021","2025-04-25 15:28:45","2025-04-25 15:28:45","","249-259","","","","","","","","","","","IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team.

OSS models are congenial for both private companies and public administrations since they provide software users and suppliers with highly responsive and innovative development models which are likely to reduce costs and to provide additional autonomy within critical technological domains. OSS are characterized by the distribution of source code to any developer interested in contributing to the provision of the code. License terms allow a developer to make unlimited copies of the source code which can be modified indefinitely by developers to fulfil particular needs. Each developer is then free to distribute her work and exploit it commercially depending on license terms. The U.S. Department of Defense (DoD) is currently introducing Open Source Software (OSS) development models through its Open Technology Development (OTD) project (Herz et al. 2006). OSS adoption is becoming popular for military purposes. Indeed, the digital transformation of the U.S. military has generated a strong need for new modes of software management. In this context, the OTD project tends to set up an innovative model for software acquisition, maintenance, updating, and renewing. Focusing on the adoption of Military Open Source Software (MOSS) models by the U.S. Department of Defense (DoD), this article suggests that the open nature of OSS development platforms induces significant organizational changes related to the acquisition, transformation and creation of a variety of OSS core capabilities. Furthermore, we suggest that the U.S. military organizations should perceive modularity in software architecture as a means to establish effective modes of knowledge management and innovation. Building on the distinction between architectural and component knowledge, we find that modular source code structuring facilitates the division, distribution and coordination of both architectural knowledge and component knowledge within heterogeneous OSS developers' communities.","2007","2025-04-25 15:28:46","2025-04-25 15:28:46","","53-59","","","","","","","","","","","","","","","","","","","","","","","","","","Remenyi, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world! OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization's success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems. The main aim of this paper is to measure the evolution of OSS using, Eclipse Metrics (EM), with Guice software (GS) as a case study.

Finding shows that software firms emphasize the co-creation of common value and partly react to the potential competitiveness on OSS ecosystems. Six themes about coopetition were identified, including spanning gatekeepers, securing communication, open-core sourcing and filtering shared code. Our work contributes to software engineering research with a rich description of coopetition in OSS ecosystems. Moreover, we also come up with several implications for software firms in pursing a harmony participation in OSS ecosystems.","2017","2025-04-25 15:28:46","2025-04-25 15:28:46","","146-160","","","304","","","","Lecture Notes in Business Information Processing","","","","","","","","","","","","","ISSN: 1865-1348","","","","","","Ojala, A; Olsson, HH; Werder, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Due to its size, it is difficult to grasp whether or not it has structure, and if so, what it may be. Our hackathon project aims to facilitate the understanding of the developer collaboration structure and relationships among projects based on the bi-graph of what projects developers contribute to by providing an interactive collaboration graph of this ecosystem, using the data obtained from World of Code [1] infrastructure. Our attempts to visualize the entirety of projects and developers were stymied by the inability of the layout and visualization tools to process the exceedingly large scale of the full graph. We used WoC to filter the nodes (developers and projects) and edges (developer contributions to a project) to reduce the scale of the graph that made it amenable to an interactive visualization and published the resulting visualizations. We plan to apply hierarchical approaches to be able to incorporate the entire data in the interactive visualizations and also to evaluate the utility of such visualizations for several tasks.","2021","2025-04-25 15:28:46","2025-04-25 15:28:46","","618-620","","","","","","","IEEE International Working Conference on Mining Software Repositories","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn","","","","","","","","","ISSN: 2160-1852","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects.

We are based on previous literature about creating institutions to governing the commons. One of the key goals is institutional reporting to members of the community, so we believe that a reporting model based on social responsibility framework is clearly suitable for this purpose. Social responsibility and sustainability are about enabling organizations to incorporate creation of social, environmental and economic value into core strategy and operations; their reporting is key to create value for organizations, their stakeholders and society as a whole.

Integrating the motivational theory and social capital theory, this article intends to explore users' contribution in OSS communities. A mixed method of SEM and fsQCA was used to perform data analysis. We found that intrinsic motivations (flow experience and self-efficacy), extrinsic motivations (perceived reputation and reciprocity), social interaction ties, community identification, and common language positively affect users' contribution intention. Trust has no effect on the contribution intention. The fsQCA results indicated that flow experience, perceived reputation, reciprocity and trust are the common core conditions of four configurations leading to contribution intention. The results suggest that OSS communities need to be concerned with users' motivations and develop social capital in order to encourage their contribution.","2023-11-02","2025-04-25 15:28:46","2025-04-25 15:28:46","","1382-1393","","6","63","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: “situated learning” (the process of acting knowledgeably and purposefully in the world) and “identity construction” (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code).

Besides this fact, it is recognized by the OSS community the need to understand OSS development process and its activities. Our goal is to investigate the state-of-art about OSS process through conducting a systematic literature review providing an overview of how the OSS community has been investigating OSS process over past years. We identified and summarized OSS process activities and their characteristics and translated them into an OSS macro process using BPMN notation. As a result, we systematically analyzed 33 studies presenting an overview of the OSS process research and a generalized OSS development macro process represented by BPMN notation with a detailed description of each OSS process activity and roles in OSS environment. We conclude that OSS process can be in practice further investigated by researchers. In addition, the presented OSS process can be used as a guide for OSS projects and be adapted according to each OSS project reality. It provides insights to managers and developers who want to improve their development process even in OSS and traditional environments. Finally, recommendations for OSS community regarding OSS process activities are provided.","2020","2025-04-25 15:28:46","2025-04-25 15:28:46","","135-144","","","","","","","IEEE International Enterprise Distributed Object Computing Conference-EDOC","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 2325-6354","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To address these challenges, businesses can use Open Source Software (OSS). Even though OSS provides many benefits, including high-quality software and substantial profit (Sohn & Mok, 2008), OSS also has a number of disadvantages. In several countries, governments have begun to recognize the importance of OSS and have started to adopt explicit policies on OSS (Cook & Horobin, 2006). Open Source Software holds several compelling benefits for businesses. Information on wide-ranging use and examples of OSS in organizations are scattered and sometimes skewed to a few OSS. The chapter identifies different OSS that are currently used or have the potential to substitute other proprietary software packages in business; how organizations share information and how OSS is used globally by organizations and governments and their implications thereof is reviewed.","2015","2025-04-25 15:28:46","2025-04-25 15:28:46","","1356-1368","","","","","","","","","","","","","","","","","","","","DOI: 10.4018/978-1-4666-7230-7.ch066","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics.

Nevertheless, user acceptance towards this type of technology has received very little attention. For this reason, the main purpose of the current study is to identify the variables and factors that have a direct effect on individual attitude towards OSS adoption.

The way the OSS products are developed and distributed is questioning the right to exclude others from using the goods and introduces the right to distribute and modify software for free. The economic impact of the Open Source Software contribution is significant, it has been estimated that it represents c.a. 30% of the software market. There is an increasing interest in studying OSS communities, however there have been a small number of studies investigating the general role of the OSS in the economic growth. Therefore the lack of theory linking the economic growth and OSS contribution represents the main theoretical problem of this paper. The goal of this article is to prove that the existence of OSS communities increases the quantity of non-rival and non-excludable goods, which - according to endogenous model of growth - leads to economic growth. Additionally the study findings undermine the neoclassical theory of property rights in terms of non-rival and non-excludable goods. The structure of the paper is organized as follows. In section 1 the article focuses on the literature addressing the role of the non-rival and non-excludable goods in the theory of growth and theory of property rights. Section 2, contains the literature review of the OSS socio-economic phenomena and argues that the neoclassical theory of rights is inadequate to explain OSS market existence. Section 3 of the paper summarizes the main conclusions and discusses the general motivation behind the creation of the non-excludable and non-rival goods as well as the diminishing role of the egoism as the origin of the economic growth. From the methodological point of view the paper represents a literature review and a critical analysis of the endogenous growth theory and the theory of property rights.","2015","2025-04-25 15:28:47","2025-04-25 15:28:47","","69-76","","2","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Models used in open software development are innovative in several ways, to the point that they are only recognized as valid models at all since they have actually produced mature and stable software more in a swift fashion. Some studies attempt to answer the OSS's development model, way to produce the quality products and distributed development model driven by motivated voluntary developers found in OSS. However, they are usually focused on handful projects and often miss to represent the whole world of OSS development. We analyze FLOSSMetrics database and SourceForge repository. By examining these, we attempt to identify 1) factual landscape of OSS projects, 2) correlation between different measures including developers' activities and consumers' interests. This analysis is also supplemented by empirical research on world re-known OSS projects to identify the implication of vendor-led OSS projects. We find that OSS projects are hardly to be seen as loci of future open innovation in several ways.

While open source software has similarly distributed decision making and involves code and information flows similar to those in ordinary supply chains, the actual networks necessary to quantify and communicate risks in software supply chains have not been constructed on large scale. This work proposes to close this gap by measuring dependency, code reuse, and knowledge flow networks in open source software. We have done preliminary work by developing suitable tools and methods that rely on public version control data to measure and comparing these networks for R language and emberjs packages. We propose ways to calculate the three networks for the entirety of public software, evaluate their accuracy, and to provide public infrastructure to build risk assessment and mitigation tools for various individual and organizational participants in open sources software. We hope that this infrastructure will contribute to more predictable experience with OSS and lead to its even wider adoption.","2018","2025-04-25 15:28:47","2025-04-25 15:28:47","","458-459","","","","","","","Proceedings of the IEEE-ACM International Conference on Software Engineering Companion","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; Microsoft Res","","","","","","","","","ISSN: 2574-1926","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Five open source software development communities are described, examined, and compared to help discover what differences may be observed. At least two dozen kinds of software informalisms are found to play a critical role in the elicitation, analysis, specification, validation, and management of requirements for developing OSS systems. Subsequently, understanding the roles these software informalisms take in a new formulation of the requirements development process for OSS is the focus of this study. This focus enables considering a reformulation of the requirements engineering process and its associated artifacts or (in)formalisms to better account for the requirements when developing OSS systems. Other findings identify how OSS requirements are decentralized across multiple informalisms, and to the need for advances in how to specify the capabilities of existing OSS systems.","2009","2025-04-25 15:28:47","2025-04-25 15:28:47","","467-494","","","14","","","","Lecture Notes in Business Information Processing","","","","","","","","","","","","","ISSN: 1865-1348","","","","","","Lyytinen, K; Loucopoulos, P; Mylopoulos, J; Robinson, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Comparing to traditional software engineering approach, we found this approach is absolutely reversed. Open source development and delivery occurs on Internet time. Developers are not confined to a geographic area. They work voluntarily on a project of their choice; they are not forced to join a particular project just because it needs more developers or the project has a high degree of urgency. Developers work for peer-recognition and self-satisfaction. In the open source community, each and every project has an equal priority. Software designed under open source is not released until the project owner thinks that the software has reached a functional stage. One of the success stories is the Linux operating system. Open Source software is always in an evolutionary stage: it never reaches a final stage. As new requirements emerge the software is enhanced by the user/developers. In this paper, we give an introduction to the insights of open source software development. We then elucidate the perceived benefits and point out the differences between open source and closed source software development approaches.

Consequently, creating and managing a security system is often the main form of precaution and it is the solution that guarantees better success rates.

There is no such impact for firms without this ecosystem of complements. Dynamic panel analysis, instrumental variables, and a variety of robustness checks are used to address measurement error concerns and to add support for a more causal interpretation of the results. For firms with an ecosystem of complements, a 1% increase in the use of nonpecuniary OSS leads to an increase in value- added productivity of between 0.002% and 0.008%.

These vulnerabilities are introduced by developers, some intentionally or negligently. In this paper, we work to quantify the relative risk that a given developer represents to a software project. We propose using empirical software engineering based analysis on the vast data made available by GitHub to create a Developer Risk Score (DRS) for prolific contributors on GitHub. The DRS can then be aggregated across a project as a derived vulnerability assessment, we call this the Computational Vulnerability Assessment Score (CVAS). The CVAS represents the correlation between the Developer Risk score across projects and vulnerabilities attributed to those projects. We believe this to be a contribution in trying to quantify risk introduced by specific developers across open source projects. Both of the risk scores, those for contributors and projects, are derived from an amalgamation of data, both from GitHub and outside GitHub. We seek to provide this risk metric as a force multiplier for the project maintainers that are responsible for reviewing code contributions. We hope this will lead to a reduction in the number of introduced vulnerabilities for projects in the Open Source ecosystem.","2022","2025-04-25 15:28:48","2025-04-25 15:28:48","","172-175","","","","","","","","","","","IEEE; IEEE Ukraine Sect; IEEE Ukraine Sect W MTT ED AP EP SSC Soc Joint Chapter; Lodz Univ Technol; NAS, Int Res & Training Ctr Informat Technologies & Syst; MES Ukraine; Ukrainian Project Management Assoc; Kharkiv Natl Univ Radioelectron; Lviv Polytechn Natl Univ","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In so doing, the initial goals of free software advocates are being dramatically expanded to include broader aims of digital freedom and social justice. Utilizing the concept of social movements from political sociology, this article first outlines the key aims and discourses surrounding the free software movement by discussing the emergence and development of F/OSS efforts such as the GNU/Linux operating system and the GNU Public License (GPL). Second, I provide examples of how the free software discourses have been adopted, altered, and expanded by a number of organized groups over the past decade. These groups, such as the Creative Commons, digital privacy advocates, and global development agencies, have adopted some of the core concepts of free software, while greatly expanding their meaning and purpose to suit their own advocacy aims. Finally, I argue that the adoption of free software discourse among these newer groups is also having a recursive effect upon the free software movement by encouraging free software advocates to conceptualize F/OSS as part of a broader movement of digital rights and social justice. In the conclusion, the prospects for the emergence of a larger technological and cultural freedom movement in the future are assessed.","2011","2025-04-25 15:28:48","2025-04-25 15:28:48","","223-239","","3, SI","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, “unresolved interdependencies” remain that cannot be addressed by such arm's length mechanisms. These interdependencies reflect, for example, unidentified or emerging knowledge-based dependencies between the community members or unaccounted relationships between ongoing community tasks. At the same time, online communities cannot resort to hierarchical coordination mechanisms such as incentives or command structures to address such interdependencies. So, how do they manage such interdependencies? To address this question, we conduct an exploratory, theory-generating case study involving qualitative and computational analyses of development activities within an open source software community: Rubinius. We analyze the ongoing management of interdependencies within the community and find that unresolved interdependencies are associated with alternatively structured sequences of activities, which we define as routines. In particular, we observe that two distinct classes of interdependencies-development and developer interdependencies-are associated with alternative forms of routine variation. We identify two generalized routine components-direct implementation and knowledge integration, which address these two distinct classes of unresolved interdependencies. In particular, direct implementation deals with development interdependencies within the code that are not already coordinated through modular interfaces, while knowledge integration resolves unaccounted interdependencies between developers. We conclude with implications for research into organizing principles for online communities and note the significance of our findings for the study of coordination in organization studies in general.","2016-12","2025-04-25 15:28:48","2025-04-25 15:28:48","","751-772","","4","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context. We conclude by discussing governance issues related to the disciplined use and reuse of open source and areas for further improvements.","2022","2025-04-25 15:28:48","2025-04-25 15:28:48","","154-163","","","","","","","","","","","Siemens; Pure Syst; Assoc Comp Machin; Graz Univ Tech; Itk Engn; Combeenation; Select Arts; Stream Diver; Hitec; Stadt Graz.at; Elsevier Journal Syst & Software","","","","","","","","","","","","","","","Felfernig, A; Fuentes, L; Cleland-Huang, J; Assuncao, WKG; Falkner, A; Azanza, M; Luaces, MAR; Bhushan, M; Semini, L; Devroey, X; Werner, CML; Seidl, C; Le, VM; Horcas, JM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper inductively derives a framework for understanding participation from the perspective of the individual software developer based on data from two software communities with different governance structures. In both communities, a need for software-related improvements drives initial participation. The majority of participants leave the community once their needs are met, however, a small subset remains involved. For this set of developers, motives evolve over time and participation becomes a hobby. These hobbyists are critical to the long-term viability of the software code: They take on tasks that might otherwise go undone and work to maintain the simplicity and modularity of the code. Governance structures affect this evolution of motives. Implications for firms interested in implementing hybrid strategies designed to combine the advantages of open source software development with proprietary ownership and control are discussed.","2006-07","2025-04-25 15:28:48","2025-04-25 15:28:48","","1000-1014","","7","52","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent examples appear to lend support to this, but there exist many detractors of OSS and resistance to the transformation it creates. Thus, it is relevant to take a closer look at the institutionalization of OSS. Objective: This paper evaluates the extent of OSS institutionalization in organizations. A practice or innovation is said to be institutionalized when it is taken-for-granted and its use becomes the norm. Method: Drawing on institutional theory, the underlying concept of organizing vision and the rhetorical theory of diffusion of innovations, we analyze OSS institutionalization through the observation of the evolution of the public discourse about OSS and, simultaneously, the observation of the rate of adoption or diffusion of OSS in organizations. Results: OSS has become institutionalized for many back-end applications and is gradually becoming institutionalized for some front-end applications, mainly in small and medium enterprises but also in organizations in the financial, publishing, education, government and public sectors. Using the rhetorical theory of diffusion of innovations in tandem with the concept of organizing vision, we provide a deep understanding of the institutionalization of OSS by showing that it has not only diffused among organizations, but is also taken-for-granted in thought and social action. The positive tone and prominence of the public discourse on OSS have an important role to play in its institutionalization. Conclusion: The institutionalization of OSS in organizations cannot be underestimated by IT and business executives as well as key players in the IT industry. Future research efforts should be pursued and directed toward the institutionalization of particular OSS applications in a variety of industries and geographic regions. (C) 2012 Elsevier B.V.

Several works have presented strategies to increase the on-boarding and engagement of new contributors, but little is known on how these diverse groups of developers self-organise to work together. To understand this, one must consider that, on one hand, platforms like GitHub provide a virtually unlimited development framework: any number of actors can potentially join to contribute in a decentralised, distributed, remote, and asynchronous manner. On the other, however, it seems reasonable that some sort of hierarchy and division of labour must be in place to meet human biological and cognitive limits, and also to achieve some level of efficiency. These latter features (hierarchy and division of labour) should translate into detectable structural arrangements when projects are represented as developer-file bipartite networks. Thus, in this paper we analyse a set of popular open source projects from GitHub, placing the accent on three key properties: nestedness, modularity and in-block nestedness - which typify the emergence of heterogeneities among contributors, the emergence of subgroups of developers working on specific subgroups of files, and a mixture of the two previous, respectively. These analyses show that indeed projects evolve into internally organised blocks. Furthermore, the distribution of sizes of such blocks is bounded, connecting our results to the celebrated Dunbar number both in off-and on-line environments. Our conclusions create a link between bio-cognitive constraints, group formation and online working environments, opening up a rich scenario for future research on (online) work team assembly (e.g. size, composition, and formation). From a complex network perspective, our results pave the way for the study of time-resolved datasets, and the design of suitable models that can mimic the growth and evolution of OSS projects.","2019-09-25","2025-04-25 15:28:48","2025-04-25 15:28:48","","","","","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The analysis can help developers, investors, and contributors, to decide which software ecosystem to invest in and where to invest. Another reason for making an analysis is to assist ecosystem coordinators in governing their ecosystem. The paper provides an insight on the free open source software ecosystem of Python. It presents an analysis of the software ecosystem itself and the different characteristics it has. Based upon the conducted analysis with the available dataset, the research concludes that the free open source software ecosystem of Python contains three ecosystem roles that define its ecosystem. Next to that, it has grown exponentially from 31 active developers in 2005 to 5,212 December 2012. These results can help set up a strategy for the future of the Python ecosystem. At this point in time, it is necessary to make arrangements for the ongoing growth of the Python ecosystem. Failing to do so can lead to a growing number of unusable features, and eventually advance to an unhealthy ecosystem.","2013","2025-04-25 15:28:49","2025-04-25 15:28:49","","13-18","","","","","","","IEEE International Conference on Digital Ecosystems and Technologies","","","","Inst Elect Elect Engineers; IEEE Ind Elect Soc; UC Berkeley; Stanford Univ; Hochschule Furtwangen; Curtin Univ Technol; Univ Studi Milano","","","","","","","","","ISSN: 2150-4938","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Communities are commonly defined as a group of people sharing common norms or values. The common interest of an OSS project is obvious: to develop software under an OSS license. When we look at the rather general definition of a community, we see that there is a similarity to the term `organization'. This paper draws parallels between OSS projects and the general elements of an organization and shows the different elements comprised in an OSS community: people, organization and assets. Each of those elements is enriched with examples from different research in the corresponding OSS research stream and provides a broad overview of the elements of OSS projects. With the help of this comparison, research on OSS can be made more focused and aligned with organizational research.","2018","2025-04-25 15:28:49","2025-04-25 15:28:49","","3-14","","","525","","","","IFIP Advances in Information and Communication Technology","","","","Harokopio Univ; IFIP WG 2 13","","","","","","","","","ISSN: 1868-4238","","","","","","Stamelos, I; GonzalezBarahona, JM; Varlamis, I; Anagnostopoulos, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This decision is partly justified due to the difficulty of bringing to the context of a classroom a real software project. The widespread presence of open source projects, however, is contributing to alleviating this problem. Several instructors have already adopted contributions to open source projects as part of their evaluation process, and these instructors reported many benefits, including the improvement on students' technical and social skills. However, little is known about the students' perceptions regarding the need to contribute to an open source project as part of a Software Engineering course. To better understand the students' challenges, benefits, and attitudes, we conducted 21 semi-structured interviews with students who took these courses in five different Brazilian universities. We also enriched this data with an analysis of commits performed in the repositories that students contributed to. We observed that even though some instructors chose the open source projects to students to work themselves, some students and even the open source community participated in the process of choosing projects and tasks. Students' contributions varied concerning both complexity (measured by the number of additions, deletions, and edited files) and diversity (measured regarding the different programming languages used). Among the benefits, students reported improving their technical skills and their self-confidence. Finally, some students found extremely important for instructors' being involved with open source initiatives (extra-classroom).","2019","2025-04-25 15:28:49","2025-04-25 15:28:49","","147-157","","","","","","","","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Comp Soc Tech Comm Software Engn; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologle Super; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif; ING; Nat Sci & Engn Res Council Canada; Prompt","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Numerous studies have extensively investigated how knowledge is acquired in these environments through a collaborative learning model that define a learning process. Such a learning process, identified either as a result of surveys or by means of questionnaires, can be depicted through a series of graphical representations indicating the steps FLOSS community members go through as they acquire and exchange skills. These representations are referred to as a-priori learning models. They are Petri net-like workflow nets (WF-net) that provide a visual representation of the learning process as it is expected to occur. These models are representations of a learning framework or paradigm in FLOSS communities. As such, the credibility of any models is estimated through a process of model verification and validation. Therefore in this paper, we analyze these models in comparison with the real behavior captured in FLOSS repositories by means of conformance verification in process mining. The purpose of our study is twofold. Firstly, the results of our analysis provide insights on the possible discrepancies that are observed between the initial theoretical representations of learning processes and the real behavior captured in FLOSS event logs, constructed from mailing archives.

In 2005, several university libraries, university college libraries and other research libraries met and discussed a joint effort to create institutional archives. The meeting resulted in the Pepia project with BIBSYS as a software partner. The project group decided to use the open source system DSpace as a software platform. A standard DSpace installation runs on a Tomcat servlet container. BIBSYS does not use this container, and we therefore needed to configure DSpace to get it to run successfully on our server. In addition we had some problems with integrating the DSpace development structure with our integrated development environment. Further we needed to create a new build process that effectively could build more than 30 applications from one source code. These changes were quite time consuming, but they were necessary so that we could have an efficient work environment. Out of the box DSpace has many of the functionalities that an institutional archive requires. In spite of this we needed to alter some of the functionality, especially the user management system. DSpace is a complex system, but with the active community we could get the help we needed. BIBSYS Brage, the result of the Pepia project, was launched as a beta version in December 2006.

Projects were characterized by project type, number and experience of developers, number of bugs, and bug resolution time. Our results provided evidence of virtual organizational learning in OSS development projects and support for several factors as determinants of performance. Team size was a significant predictor, with mid-sized project teams functioning best. Teams of three to seven developers exhibited the highest efficiency over time and teams of eight to 15 produced the lowest mean time for bug resolution. Increasing the percentage of bugs assigned to specific developers or boosting developer participation in other OSS projects also improved performance. Furthermore, project type introduced variability in project team performance. (c) 2008 Elsevier B.V.

However, limited research has been undertaken that examines and explains the practical mechanisms or work practices used by companies and their developers to pursue their commercial and technical objectives when engaging with OSS projects. This research investigates the variety of work practices used in public communication channels by company contributors to engage with and contribute to eight community OSS projects. Through interviews with contributors to the eight projects we draw on their experiences and insights to explore the motivations to use particular methods of contribution. We find that companies utilise work practices for contributing to community projects which are congruent with the circumstances and their capabilities that support their short- and long-term needs. We also find that companies contribute to community OSS projects in ways that may not always be apparent from public sources, such as employing core project developers, making donations, and joining project steering committees in order to advance strategic interests. The factors influencing contributor work practices can be complex and are often dynamic arising from considerations such as company and project structure, as well as technical concerns and commercial strategies. The business context in which software created by the OSS project is deployed is also found to influence contributor work practices.","2021-07-01","2025-04-25 15:28:49","2025-04-25 15:28:49","","1381-1401","","7","47","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines this corporatizing effect by studying the relationship between peer-oriented social structures and goal-oriented technical structures in the Plone community. Social structures are said to exhibit assortative mixing, a like attract like characteristic whereas technical structures exhibits an opposite effect of disassortative mixing. Our first finding suggests that the patterns of collaborative contributions and interdependences among software modules exhibit the characteristic of disassortative mixing. Specifically, Plone developers were more likely to contribute to modules that already have a high concentration of contributions, which in turn lead to an increase in module reuse over time. This finding contributes to the debate of whether social systems are strictly assortative, and technological systems strictly disassortative (Newman, 2002).

The data, in one hand, encapsulates the tacit knowledge on the evolution of the software itself. And, on the other hand, provides the history of communication and collaboration of the community. Acquisition and analysis of such data has been mostly manual or semi-automated and error-prone, mainly due to unstructured and substandard data representation. This increases the validity threat of the reported results and makes it incomparable across the studies. With the advancement of data management tools and technologies, many third party data providers are putting serious effort to provide OSS project's data in a standard and platform independent format. In this paper, we propose a framework to fully automate the analysis and visualization of OSS evolution data through the use of existing data services. As a proof of concept we implemented a tool named POMAZ. We demonstrate the applicability of the tool in the context of two related open source projects FFmpeg and GStreamer.","2013","2025-04-25 15:28:49","2025-04-25 15:28:49","","273-280","","","","","","","","","","","EMMi Lab; Tampere Univ Technol; Univ Tamepre; Tampere Univ Appl Sci; MindTrek Assoc","","","","","","","","","","","","","","","Lugmayr, A; Franssila, H; Karkkainen, H; Paavilainen, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects are typically organized as edge organizations lacking an explicit management regime to control and coordinate decentralized project work. However, a growing number of OSS projects are developing, delivering, and supporting large-scale software systems, displacing proprietary software alternatives. Recent empirical studies of OSS projects reveal that OSS developers often self-organize into organizational forms we characterize as evolving socio-technical interaction networks (STINs). STINs emerge in ways that effectively control semi-autonomous OSS developers and coordinate project activities, producing reliable and adaptive software systems. In this paper, we examine how practices and processes enable and govern OSS projects when coalesced and configured as contingent, socio-technical interaction networks. We draw on data sources and results from two ongoing case studies of governance activities and elements in a large OSS project.","2010","2025-04-25 15:28:49","2025-04-25 15:28:49","","130-142","","","319","","","","IFIP Advances in Information and Communication Technology","","","","Int Federat Informat Proc Work Grp 2 13","","","","","","","","","ISSN: 1868-4238","","","","","","Agerfalk, P; Boldyreff, C; GonzalezBarahona, JM; Madey, GR; Noll, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS represents an effective development model because it harnesses the decentralized efforts of many developers in a way that scales. As OSS developers work independently on interdependent modules, they create a larger cohesive whole in the form of an ecosystem, leaving traces of their contributions and collaborations. Data harvested from these traces enable the study of large-scale decentralized collaborative work. We present curated data on the activity of tens of thousands of developers in the Rust ecosystem and the evolving dependencies between their libraries. The data covers eight years of developer contributions to Rust libraries and can be used to reconstruct the ecosystem's development history, such as growing developer collaboration networks or dependency networks. These are complemented by data on downloads and popularity, tracking dynamics of use, visibility, and success over time. Altogether the data give a comprehensive view of several dimensions of the ecosystem.","2022-11-16","2025-04-25 15:28:50","2025-04-25 15:28:50","","","","1","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Like its financial counterpart, technical debt comprises a principal and an interest. Not addressing it in time leads to development crises, where focus and resources must be shifted to address existing issues. Existing software tools allow measuring the level of debt and pinpointing its sources, which can help practitioners control it. In the present paper we aim to investigate the prevalence, characteristics, and evolution of technical debt in several open-source applications. We used SonarQube to study 112 application versions that covered more than 15 years of development for each application. We studied the way debt characteristics and source code distribution evolved over the target applications' lifecycles. We addressed concerns regarding the accuracy of the analysis and illustrated some of the limitations of existing tools. We observed that a small number of issue types were responsible for most of the debt. We found that each application had its own technical debt particularities. As future work, we aim to expand our selection of analysis tools, leverage open data sets, and extend our investigation to other systems and types of software.","2022","2025-04-25 15:28:50","2025-04-25 15:28:50","","174-185","","","","","","","","","","","INSTICC","","","","","","","","","","","","","","","Kaindl, H; Mannion, M; Maciaszek, L","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the lens of the integrative model of trust (IMoT), hypotheses regarding interactions between trust and community citizenship behaviors (CCBs - as OSSPC participating activities) are developed. Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust -> CCBs and the CCBs -> Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust -> CCBs relationship. These findings are explained from several theoretical perspectives, which provide directions for future research and help community management to maintain sustained participation.","2022-09-03","2025-04-25 15:28:50","2025-04-25 15:28:50","","907-920","","5","62","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Python scripts, activated by Blender, allow to allocate data into a spatial database implemented through PostgreSQL and PostGis, that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, are so transferred in PostGIS. These information can be retrieved by Blender using other Python scripts, so Blender fully interacts with 3D data allocated in PostGIS. These data can be also accessed by many other clients, both directly using a database client, as using other protocols (like HTTP on the internet).

In this paper, we connect open source software from different communities with user feedbacks in StackOverflow, and explore the correlation between the popularity of posts and time. Finally we rank open source software through using information of connected posts in StackOverflow and compare our ranking result with several influential ranking results like DB-Engines and personal blogs.

The traditional market failure argument suggests that innovation is characterized by high investment and low copy cost, and firms have difficulty in internalizing the fruits of their innovative effort. Thus, technology firms are seeking more patents, expanding their scope and overhauling their business models around intellectual property. Yet paradoxically, with the progress and development of information technology, open source software (OSS) plays an important role in expanding enterprise informatization. For example, Linux is developed quickly by this open way. Some firms have found the ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is one example. In this article, the author introduces a model of OSS based on its network effects to understand how the enterprises decide their activities in this open market competition. This article describes the inherent reasons of open source movement from the view of the oligopoly structure. At the same time, this article analyses the effect of leader enterprise and follower enterprise on market structure and the different activities of these enterprises after the source has been opened. Finally, we make suggestions that companies at the leading edge are often in such a strong position that they do need the support of down-streams companies to broaden their technologies successfully and to decrease their risks in order to leverage the value of the technological portfolio. On the other hand, this article suggests that follower enterprises have incentive to take part in the development of open-source software only when the market has grown up.","2008","2025-04-25 15:28:51","2025-04-25 15:28:51","","669+","","","254","","","","International Federation for Information Processing","","","","","","","","","","","","","ISSN: 1571-5736","","","","","","Xu, LD; Tjoa, AM; Chaudhry, SS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although open source software is used widely, in this study the authors examine the adoption of open source software in the public sector. As such, the paper uses content analysis to review published articles on open source software in the public sector or government organizations between 2003 and 2012 across the regions (Africa, America, Asia, and Europe). The results suggest that that there is no-one-size-fit-all to open source software adoption benefits to the public sector in different regions. The results also show that technical benefits, vendor independence and customization are considered to be important for open source software adoption in public sector organizations. While this suggests that public sector organizations perceive open source software as one step towards vendor independence, customization is considered a very important benefit of open source software adoption in Asia than is the case in America.","2015","2025-04-25 15:28:51","2025-04-25 15:28:51","","2242-2251","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE Comp Soc; Univ Hawaii, Shidler Coll Business; Univ Hawaii, Dept EE; Univ Hawaii, Informat Sci Program; ONR; AFOSR; Natl Sci Fdn; IEEE Syst Sci & Cybernet Soc; ACM; SIAM; IEEE Hawaii Sect; IEEE Control Syst Soc; IEEE Grp Informat Theory; IEEE Grp Automat Control; ARO; Reg Med Program Hawaii; Univ Hawaii, Coll Business Adm; Nasdaq","","","","","","","","","ISSN: 1060-3425","","","","","","Bui, TX; Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding the structure of software systems can provide useful insights into software engineering efforts and can potentially help the development of complex system models applicable to other domains. In this paper, we analyze one of the most popular open-source Linux meta packages/distributions called the Gentoo Linux. In our analysis, we model software packages as nodes and dependencies among them as edges. Our empirical results show that the resulting Gentoo network cannot be easily explained by existing complex network models. This in turn motivates our research in developing two new network growth models in which a new node is connected to an old node with the probability that depends not only on the degree but also on the “age” of the old node. Through computational and empirical studies, we demonstrate that our models have better explanatory power than the existing ones. In an effort to further explore the properties of these new models, we also present some related analytical results. (C) 2008 Elsevier B.V.

In order to differentiate between an increasing variety of commercialization approaches, one may distinguish between projects with one dominating company, so called single vendor projects and those where more than one company is active, so called multi vendor projects. Furthermore, in order to structure different approaches, a project's history is equally of importance in terms of whether a project was initiated by a firm or a community. In this paper, we therefore analyze and compare single and multi vendor as well as firm initiated and community initiated OSS projects with regard to technical contribution of voluntary and paid project members.

The concept of peer governance describes the interaction and convergence of companies, foundations, voluntary users and professionals in its development. Methodology/approach: The research is based on the documentary method and an organizational history approach. For this, primary and secondary digital sources were collected: institutional and FLOSS sites, blogs, community lists, documents and platforms. Originality/Relevance: The work allows progress, from a sociotechnical perspective, in understanding FLOSS developments and the coevolution of their technical components and community dynamics. Main results: Three levels of governance are identified: 1. the software itself; 2. the community; 3. the ecosystem. Development cycles; community participation and organization; actors and business models, definitions and controversies, are analyzed. GNOME's trajectory is marked by the confluence of interests and coopetition between corporate actors and the FLOSS ecosystem. The life cycle shows a constant activity, which implies redefinition of its components, technological infrastructure and leadership. It is not exempt from controversies and bifurcations, similar to those evidenced in projects of this type. Theoretical/methodological contributions: It contributes to the concept of peer governance and its usefulness for case analysis. Reflection on data sources and research resources on the Internet is promoted. Social/managerial contributions: It contributes to the understanding of new forms of management and decision-making in technological development projects.","2020-12","2025-04-25 15:28:51","2025-04-25 15:28:51","","438-465","","3","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because of the growing national interest in OSS, we surveyed efforts of twenty major world economies, otherwise known as the Group-of-Twenty (G-20). We examined over forty-five national initiatives within the twenty countries and we were able to identify seven distinctive common strategies applied within the past ten years. Each strategy has been adapted by at least three countries. The result of the survey shows a significant growth in interest to support OSS by major economies. Based on the result of our survey we present a stepwise process to align the seven strategies to national objectives and market needs, and provide a prioritization scheme for strategy implementation.","2013","2025-04-25 15:28:51","2025-04-25 15:28:51","","","","","","","","","","","","","","","","","","","","","","","","","","","","Jakobs, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the widespread availability of several large software systems that have been developed using an “open source” development approach, we now have a chance to examine these systems in detail, and see if their evolutionary narratives are significantly different from commercially developed systems. This paper summarizes our preliminary investigations into the evolution of the best known open source system: the Linux operating system kernel. Because Linux is large (over two million lines of code in the most recent version) and because its development model is not as tightly planned and managed as most industrial software processes, we had expected to find that Linux was growing more slowly as it got bigger and more complex. Instead, we have found that Linux has been growing at a super-linear rate for several years. In this paper; we explore the evolution of the Linux kernel both at the system level and within the major subsystems, and we discuss why we think Linux continues to exhibit such strong growth.","2000","2025-04-25 15:28:51","2025-04-25 15:28:51","","131-142","","","","","","","PROCEEDINGS - IEEE INTERNATIONAL CONFERENCE ON SOFTWARE MAINTENANCE","","","","IEEE, Comp Soc Techn Council Software Engn","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These have been used as the basis to support the discovery of successful genetic modifications of the microbial metabolism to address industrial goals. However, the use of these methods has been restricted to bioinformaticians or other expert researchers. The main aim of this work is, therefore, to provide a user-friendly computational tool for Metabolic Engineering applications. Results: OptFlux is an open-source and modular software aimed at being the reference computational application in the field. It is the first tool to incorporate strain optimization tasks, i.e., the identification of Metabolic Engineering targets, using Evolutionary Algorithms/Simulated Annealing metaheuristics or the previously proposed OptKnock algorithm. It also allows the use of stoichiometric metabolic models for (i) phenotype simulation of both wild-type and mutant organisms, using the methods of Flux Balance Analysis, Minimization of Metabolic Adjustment or Regulatory on/off Minimization of Metabolic flux changes, (ii) Metabolic Flux Analysis, computing the admissible flux space given a set of measured fluxes, and (iii) pathway analysis through the calculation of Elementary Flux Modes. OptFlux also contemplates several methods for model simplification and other pre-processing operations aimed at reducing the search space for optimization algorithms. The software supports importing/exporting to several flat file formats and it is compatible with the SBML standard. OptFlux has a visualization module that allows the analysis of the model structure that is compatible with the layout information of Cell Designer, allowing the superimposition of simulation results with the model graph. Conclusions: The OptFlux software is freely available, together with documentation and other resources, thus bridging the gap from research in strain optimization algorithms and the final users. It is a valuable platform for researchers in the field that have available a number of useful tools. Its open-source nature invites contributions by all those interested in making their methods available for the community. Given its plug-in based architecture it can be extended with new functionalities. Currently, several plug-ins are being developed, including network topology analysis tools and the integration with Boolean network based regulatory models.","2010-04-19","2025-04-25 15:28:53","2025-04-25 15:28:53","","","","","4","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On these platforms, various information is obtained from developer activities that can then be used as developer metrics to solve a variety of challenges. In this study, we proposed new developer metrics extracted from the issue, commit, and pull request activities of developers on GitHub. We created developer metrics from the individual activities and combined certain activities according to some common traits. To evaluate these metrics, we created an item-based project recommendation system. In order to validate this system, we calculated the similarity score using two methods and assessed top-n hit scores using two different approaches. The results for all scores with these methods indicated that the most successful metrics were binary_issue_related, issue_commented, binary_pr_related, and issue_opened. To verify our results, we compared our metrics with another metric generated from a very similar study and found that most of our metrics gave better scores that metric. In conclusion, the issue feature is more crucial for GitHub compared with other features. Moreover, commenting activity in projects can be equally as valuable as code contributions. The most of binary metrics that were generated, regardless of the number of activities, also showed remarkable results. In this context, we presented improvable and noteworthy developer metrics that can be used for a wide range of open-source software development challenges, such as user characterization, project recommendation, and code review assignment.","2021-02","2025-04-25 15:28:53","2025-04-25 15:28:53","","","","3","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is especially true for open source software systems (OSSS), when many developers from different backgrounds interact, share their ideas and contribute towards the development and improvement of a software product. The evolution of an OSSS is a continuous process of source code development, adaptation, improvement and maintenance. Studying changes to the various characteristics of source code can help us understand the evolution of a software system. In this paper, the software evolution process is analyzed using a proposed Evolution curve (E-curve) method, which is an implementation language independent method based on information theoretic metrics.

Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach - To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents' opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings - The analysis of the data reveals that the individual participant's satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value - Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members' satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.","2015","2025-04-25 15:28:53","2025-04-25 15:28:53","","791-813","","4","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A matrix differentiating four types of OSSDPs: firm- versus community-initiated projects and one participating firm (single-vendor projects) versus many firms (multivendor projects), and accompanying hypotheses regarding a firm's participation for each type are developed. Using data from 83 Eclipse projects to test the hypotheses, findings indicate that (1) firms more actively employ both leadership and resource deployment in firm-initiated projects than in community-initiated ones and (2) firms are more likely to use resource deployment control over leadership control in multivendor projects.

This means that the end user does not have access to source code, cannot make changes to the software to suit individual needs, and the software cannot be redistributed. Open source software, on the other hand, allows its user access to source code, thereby allowing them to customize the software according to their needs and integrate it with existing software infrastructure: and, if need be, redistribute it. Open source software, therefore, has potential benefits for government agencies in terms of electronic service provision to general public.

This article considers the dynamics of value creation fuelling the proliferation of OSS and examines the business model factors that enable value capture. After interviewing leaders from over 20 OSS firms and organisations through early 2006, we found that three factors were consistently important in defining a vendor's adoption of a given business model: software licence choice, which takes into account intellectual property ownership; management of developer communities; and the unique features of the markets and product categories in which the vendor participates. Considering these factors, we characterise seven business models. One striking finding is that it is rare to find business-model purity.

The Air Traffic Management industry (ATM) is the only case considered in this paper. However, it is assumed that the regulatory advantage of OSS is not specific to that industry. The second proposal is about how to establish such a regulation through OSS. It is argued that the legal ownership of the OSS product should be assigned to a public organization, preferably to an organization that would be dedicated to monitor and promote the evolution of that product. The motivation for these proposals is based on the analysis of possible scenarios of OSS ownership in the case of ATM.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses.

Especially in the higher education sector, IT is playing a vital role in the advancement of teaching and learning practices. Most of the educational organizations have already adopted smart learning environment by upgrading their infrastructure and with proper capacity building among staff members. But in the education sector, sustainability of technology is always being a challenge. To develop learning materials, many institutions have already started using free and open source software (FOSS) tools. FOSS gives freedom to the developer with the provision of various customization options as per the requirements of the class or subject. Moreover, in the longer run, free and open source software could be considered as the best option in education for e-learning implementation, for sustainability. There are many tools which are available for e-learning resource development. Some of them are available online and some are available as an installer for the various platform. In order to adapt ICT in education, especially in non-IT specialization, the faculty members need the training to learn and implement these tools in their classes. But there are many tools, which are specially designed for educators with basic knowledge of computers. Educators can plan their sessions, based on content, duration as well as the level of the subject and the students. This research paper will highlight various aspects of the implementation of FOSS, in education by using such easy-to-implement tools and techniques. This would provide general guidelines for the development of various e-learning solutions for technology-enhanced teaching and learning practices in higher education.","2017","2025-04-25 15:28:54","2025-04-25 15:28:54","","1075-1079","","","","","","","","","","","Int Org Ctr Acad Res","","","","","","","","","","","","","","","Uslu, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, given the many complex and novel issues that surround the use of OSS, the process of OSS adoption is not well-understood. We investigated this issue using a framework derived from innovation adoption theory which was then validated in an organisation which had embarked on a large-scale of adoption of OSS. The framework comprised four macro-factors - external environment, organisational context, technological context and individual factors. We then investigated these factors in a large-scale survey. Overall, the findings suggest a significant penetration of OSS with general deployment in two industry sectors consultancy/sotware house and service/communication - and more limited deployment in government/public sector. However, the existence of a coherent and planned IT infrastructure based on proprietary; software served to impede adoption of OSS. Finally, individual-relevant factors such as support for the general OSS ideology and committed personal championship of OSS were found to be significant.","2005","2025-04-25 15:28:55","2025-04-25 15:28:55","","217-226","","","","","","","","","","","IEEE Comp Soc; ACM SIGSOFT","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects introduce particular challenges that have to be understood in order to gain the benefits. One such challenge is getting newcomers onboard into the projects effectively. Similar challenges may be present in other self-organised, virtual team environments. In this paper we present preliminary observations and results of in-progress research that studies the process of onboarding into virtual OSS teams. The study is based on a program created and conceived at Stanford University in conjunction with Facebook's Education Modernization program. It involves the collaboration of more than a dozen international universities and nine open source projects. More than 120 students participated in 2013. The students have been introduced to and supported by mentors experienced in the participating OSS projects.

To achieve our objective, we selected three complex, widely used target applications for which access to their entire development history and source code was available. To enable cross-application comparison, we restricted our selection to GUI-driven software developed on the Java platform. We focused our examination on released versions, resulting in 111 software releases included in our case study. These covered more than 10 years of development for each of the applications. For each version, we determined its maintainability using three distinct quantitative models of varying complexity. We examined the relation between software size and maintainability and studied the main drivers of important changes to software maintainability. We contextualized our findings using manual source code examination. We also carried out a finer grained evaluation at package level to determine the distribution of maintainability issues within application source code.

This process is reviewed and illustrated with OsiriX, a fast DICOM viewer program for the Apple Macintosh. Materials and methods OsiriX is an oss for the Apple Macintosh under Mac OS X v10.4 or higher specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: multiplanar reconstruction, surface rendering, volume rendering and maximum Intensity projection. All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT). OsiriX was developed using the Apple Xcode development environment and Cocoa framework as both a DICOM PACS workstation for medical imaging and an image processing software package for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging. Results OsiriX is an open source program by Antoine Rosset, a radiologist and software developer, was designed specifically for the needs of advanced imaging modalities. The software program turns an Apple Macintosh into a DICOM PACS workstation for medical imaging and image processing. OsiriX is distributed free of charge under the GNU General Public License and its source code is available to anyone. This system illustrates how open software development for medical imaging tools can be successfully designed, implemented and disseminated. Conclusion oss development can provide useful cost effective tools tailored to specific needs and clinical tasks. The integrity and quality assurance of open software developed by a community of users does not follow the traditional conformance and certification required for commercial medical software programs. However, open software can lead to innovative solutions designed by users better suited for specific tasks.","2006-12","2025-04-25 15:28:55","2025-04-25 15:28:55","","187-196","","4","1","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Data model can be accessed by desktop application as well as from Internet. This second option is becoming today the most requested. But in order to share 3D data model through Internet it is necessary to configure a suitable system. A 3D model can be shared on Internet in different ways. It is possible to incorporate a model inside an executable or 3D PDF file or build something like a multimedia application (i.e. flash based). However a better option is to put a model inside a geospatial database and build suitable web services to access it using Internet browsers. This second option can be performed using different solutions for web servers, development platforms and programming languages. Fundamental for this option is the construction of the model that should be structured, according a conceptual model to be replicable and interoperable. Hence, the model should be stored in a geospatial database in order to be accessed by an application running under a web server, so allowing access to the model. All this is the object of the research-Management and use of distributed 3D data by open source WebGIS software-that is part of the Italian PRIN 2007 research project: Interoperability and cooperative management of geographic, dynamic, multi-dimensional and distributed data with Free and Open Source GIS (Principal investigator Paolo Zatelli), aimed to build urban and suburban 3D models with CAD software or solid modellers, share them with a 3D Web Feature Service Open Geospatial Consortium web feature service like, and them using Internet browsers all done using only free and open source software. The research work, here illustrated, which was funded by previous research project, deals with the construction of a suitable model and the storage of the model inside a geospatial database. The work is based on the use of free and open source software; Blender and PostgreSQL with PostGIS have been used, respectively, to draw objects of the model and save their data with the help of some Python scripts; the server side part of the system has been realized using Tomcat with servlets and applets all written in Java. Buildings have been modelled according to GIANT3D model (Geographical Interoperable Advanced Numerical Topological 3-Dimensional Model) previously developed in the research “PRIN 2004”, regarding “Evolved structure of numerical cartography for GIS and WebGIS”. Python scripts, activated by Blender, allow saving data into a spatial database implemented through PostgreSQL and PostGIS that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, is so transferred in PostGIS.

These challenges of understanding and evolving existing code can be illustrated in academic settings by leveraging the rich and varied volume of Open Source Software (OSS) code. To teach SE with OSS, however, it is necessary to select uniform projects of appropriate size and complexity. This paper reports on our search for suitable OSS projects to teach an introductory SE course with a focus on maintenance and evolution. The search turned out to be quite labor intensive and cumbersome, contrary to our expectations that it would be quick and simple. The chosen projects successfully demonstrated the maintenance challenges, highlighting the promise of using OSS. The burden of selecting projects, however, may impede widespread integration of OSS into SE and other computing courses.","2014","2025-04-25 15:28:55","2025-04-25 15:28:55","","397-402","","","","","","","","","","","Assoc Comp Machinery; ACM Special Interest Grp Comp Sci Educ","","","","","","","","","","","","","","","Dougherty, J; Nagel, K; Decker, A; Eiselt, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Increasing the amount of students that pursue STEM majors is important because the projected job growth in the STEM field compared to non-STEM jobs is 33%. OSALT provides cost-effective alternatives to commercial products such as Microsoft Office Suite and Adobe Photoshop. Second, creating Virtual Machines (VMs) is another avenue to teach complex concepts in computer science, engineering, and Information Technology (IT). Third, cloud computing is an inexpensive way for clients to access information from multiple locations and devices. Fourth, universities can use the Operating System (OS) Linux and its various distributions as replacements for commercial operating systems like Windows in order to reduce IT costs.

To assess the state of marine fish and zooplankton, population surveys are often repeated annually using standardized sampling protocols and analysis techniques to establish trustworthy stock status. However, although transparency and repeatability are recognised as important principles of this process, it is often difficult to obtain comprehensive documentation of metadata and data processing steps. This is particularly challenging for workflows that include manual processing steps. StoX was principally built to process research-vessel survey data, and we have included several standard survey estimation models. The software was developed to be robust and versatile and aimed at the open source community, such that users could easily build their own models. StoX is fully integrated with R to utilize the large number of R-packages and enable any StoX function and stock estimation model to be controlled using R. There has been a large need for a freely available software for research-vessel survey estimation, and StoX is tested in surveys carried out in four continents and is the official tool for many important fish stock surveys. The basic workflow and transparency principles of StoX, together with a customizable GUI, makes StoX applicable for any geographically coded surveys. Future versions of StoX will include statistical models to estimate the catch composition in commercial fisheries. In fields such as conservation management, there is also a need to document the estimation methods, and additional estimation and analyses models, including biodiversity indices are currently implemented. In parallel, we envision a closer web service integration with existing international and national data centres.","2019-09","2025-04-25 15:28:55","2025-04-25 15:28:55","","1523-1528","","9","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context. Can rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 15:28:55","2025-04-25 15:28:55","","1449-1469","","4","63","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We propose an open source software platform for the planning of image-guided interstitial ablation procedures, providing generic functionality and support for specialized plug-ins. METHODS: The patient's image data is loaded or streamed into the system and the relevant structures are segmented. The user places fiducial points as ablation needle entries and tips, sets the ablation times, and the thermal dose is calculated by a dose engine. The thermal dose is then visualized on the 2D image slices and 3D rendering using a combination of isodose lines and surfaces. Quantitative feedback is provided by dose volume histograms. The treatment plan can be iteratively edited until satisfactory dose distribution is achieved. We performed a usability study with eight novice users in which they were asked to create a satisfactory treatment plan. RESULTS: Interventionists can use the proposed system to create and visualize thermal ablation plans. Researchers can use the platform to create a wide range of specialized applications by adding plug-ins for various types of ablation methods, thermal models, and dose calculation engines. Existing extensions of the platform can provide real-time imaging and tracked or robotic navigation to aid the user in optimal needle placement. From our usability study, the users found the visual information well represented and the platform intuitive to use. The users averaged 4.4 recalculation attempts before finding an optimal treatment, which was evaluated as 100% necrosis of the tumor. CONCLUSION: The developed platform fulfills a demand for a universal and shared ablation planning system. While also being supported by the state-of-the-art development of specialized plug-ins, the open source system can adapt to the desired dose calculation or ablation procedure.","2021","2025-04-25 15:28:56","2025-04-25 15:28:56","","","","","11315","","","","Proceedings of SPIE","","","","SPIE","","","","","","","","","ISSN: 0277-786X","","","","","","Fei, B; Linte, CA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is the first step for any process involving identification, time series analysis or change detection using a large set of imagery over a region. Most of the reliable procedures involve time consuming and laborious manual methods of finding the corresponding matching features of the input image with respect to reference. Also the process, as it involves human interaction, does not converge with multiple operations at different times. Automated procedures rely on accurately determining the matching locations or points from both the images under comparison and the procedures are robust and consistent over time. Different algorithms are available to achieve this, based on pattern recognition, feature based detection, similarity techniques etc. In the present study and implementation, Correlation based methods have been used with a improvement over newly developed technique of identifying and pruning the false points of match. Free and Open Source Software (FOSS) have been used to develop the methodology to reach a wider audience, without any dependency on COTS (Commercially off the shelf) software. Standard deviation from foci of the ellipse of correlated points, is a statistical means of ensuring the best match of the points of interest based on both intensity values and location correspondence. The methodology is developed and standardised by enhancements to meet the registration requirements of remote sensing imagery. Results have shown a performance improvement, nearly matching the visual techniques and have been implemented in remote sensing operational projects. The main advantage of the proposed methodology is its viability in production mode environment. This paper also shows that the visualization capabilities of MapWinGIS, GDAL's image handling abilities and OSSIM's correlation facility can be efficiently integrated to effectively use in remote sensing based production environment.","2014","2025-04-25 15:28:56","2025-04-25 15:28:56","","1121-1128","","","40-8","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences","","","","ISPRS Tech Commiss; Int Soc Photogrammetry & Remote Sensing; Indian Soc Remote Sensing; Indian Soc Geomat","","","","","","","","","ISSN: 1682-1750","","","","","","Dadhwal, VK; Diwakar, PG; Seshasai, MVR; Raju, PLN; Hakeem, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Industrial users adopting to OSS and the underlying concepts need to consider changing their software development practices and organization in order to benefit from the OSS model. These changes may involve both technical and non-technical aspects. Openness and collaboration with a community are two non-technical concepts that may require such changes, while evaluating OSS products or evaluating different strategies for integrating OSS products are two technical aspects that may require adoption. The objective of this paper is to create an awareness for the adoption of OSS in an industrial context. OSS can be used in different ways. Four categories of using OSS are presented by discussing motivation, implication and experience for each category. The main conclusion from this work is that organizations should have a realistic expectation of both the designated benefits and extension of organizational changes necessary to adopt to OSS.

Architectural decay is caused by repeated, sometimes careless changes to a system during its lifespan. Despite decay's prevalence, there is a relative dearth of empirical data regarding the nature of architectural changes that may lead to decay, and of developers' understanding of those changes. In this paper, we take a step toward addressing that scarcity by introducing an architecture recovery framework, ARCADE, for conducting large-scale replicable empirical studies of architectural change across different versions of a software system. ARCADE includes two novel architectural change metrics, which are the key to enabling large-scale empirical studies of architectural change. We utilize ARCADE to conduct an empirical study of changes found in software architectures spanning several hundred versions of 23 open-source systems. Our study reveals several new findings regarding the frequency of architectural changes in software systems, the common points of departure in a system's architecture during the system's maintenance and evolution, the difference between system-level and component-level architectural change, and the suitability of a system's implementation-level structure as a proxy for its architecture.","2017-06","2025-04-25 15:28:56","2025-04-25 15:28:56","","1146-1193","","3","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems. It is found that the predicted results of the computational method outperform various ARIMA models.

Recent studies on emergent leadership shed light on additional dimensions such as intellectual stimulation in collaborative communications. This paper aims to mine communication styles and identify emergent leadership behaviors in OSS communities, using issue comments data. We start with the construction of 6 categories of leadership behaviors based on existing leadership studies. Then, we manually label leadership behaviors in 10,000 issue comments from 10 OSS projects, and extract 304 heuristic linguistic patterns which represent different types of emergent leadership behaviors in flexible and concise manners. Next, an automated algorithm is developed to merge and consolidate different pattern sets extracted from multiple projects into a final pattern ranking list, which can be applied for the automatic leadership identification. The evaluation results show that iLead can achieve a median precision of 0.82 and recall of 0.78, outperforming ten machine/deep learning baselines. We argue that emergent leadership behaviors in issue discussion should be taken into consideration to broaden existing OSS leadership viewpoints.","2023","2025-04-25 15:28:56","2025-04-25 15:28:56","","73-84","","","","","","","IEEE International Conference on Software Analysis Evolution and Reengineering","","","","IEEE; IEEE Comp Soc; Macau Univ Sci & Technol","","","","","","","","","ISSN: 1534-5351","","","","","","Zhang, T; Xia, X; Novielli, N","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They were individuals who, despite their affiliation, contributed to the project on their own. They decided which project to join, and their contributions were personal in nature, even when in some cases they were employees of companies with some interests in the project. GNU, the first of such communities, and some others that emerged during the late 1980s and 1990s, followed this pattern. During the 1990s corporate interests started to have a role in some FLOSS communities. Companies hired people from those communities to gain influence, or tasked their employees to contribute to them, again with the idea of influencing their decisions. During the 2000s, corporate communities, in which companies are first-class citizens, have emerged, changing the rules and redefining the role of volunteers and non-affiliated individuals. However, the role of developers, with independence of the company for which they work, is still important even in these communities. This paper addresses this transition from volunteer-based to company-based development communities, and explores the structure and behavior of the latter.","2013-09","2025-04-25 15:28:56","2025-04-25 15:28:56","","173-180","","5, SI","55","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As techniques for acquiring images increase in complexity, resulting in larger multidimensional datasets, imaging software must adapt. ImageJ is an open-source image analysis software platform that has aided researchers with a variety of image analysis applications, driven mainly by engaged and collaborative user and developer communities. The close collaboration between programmers and users has resulted in adaptations to accommodate new challenges in image analysis that address the needs of ImageJ's diverse user base. ImageJ consists of many components, some relevant primarily for developers and a vast collection of user-centric plugins. It is available in many forms, including the widely used Fiji distribution. We refer to this entire ImageJ codebase and community as the ImageJ ecosystem. Here we review the core features of this ecosystem and highlight how ImageJ has responded to imaging technology advancements with new plugins and tools in recent years. These plugins and tools have been developed to address user needs in several areas such as visualization, segmentation, and tracking of biological entities in large, complex datasets. Moreover, new capabilities for deep learning are being added to ImageJ, reflecting a shift in the bioimage analysis community towards exploiting artificial intelligence. These new tools have been facilitated by profound architectural changes to the ImageJ core brought about by the ImageJ2 project. Therefore, we also discuss the contributions of ImageJ2 to enhancing multidimensional image processing and interoperability in the ImageJ ecosystem.","2021-01","2025-04-25 15:28:57","2025-04-25 15:28:57","","234-249","","1, SI","30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are continuing debates over the future of software and, in particular, the competition between OSS and proprietary software. Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. The government environment is changing rapidly in areas as diverse as homeland security and social services. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied-especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 15:28:57","2025-04-25 15:28:57","","227-238","","2","44","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach This study focuses on dependencies using three network metrics - degree centrality, betweenness centrality and closeness centrality - in developer and module networks. A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks. Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success. Originality/value This study is the first attempt to consider the network metrics in both module networks of the technical sub-system and developer networks of the social sub-system to better understand their influences on project success.","2023-03-21","2025-04-25 15:28:57","2025-04-25 15:28:57","","895-915","","2","36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the context of a field investigation of these risks, several potential scenarios of OSS risk to organizations were identified, with two of them appearing as primary. The first primary scenario is the potential loss of control over revenue generating proprietary software when OSS source code and proprietary software source code are mixed together in one primary software works. The second primary risk scenario is the potential loss of control over software products or services offered within an organization due to legal disputes about intellectual property (IP).

Test results are automatically published to a format capable of being consumed by script catalogues and social coding sites. This would serve as an independent signal of script trustworthiness and quality to script consumers and would allow developers to be made quickly aware of quality issues. As a result, potential consumers of scripts can be assured that a script is likely to work when applied to their particular environment.

Investigating the types of norms that exist in open source projects and their efficacy (i.e. the usage of norms) in enabling smoother functioning however has not received much attention from the normative multi-agent systems (NorMAS) community. This paper makes two contributions in this regard. First, it presents norm compliance results from a case study involving three open source Java projects. Second, it presents an architecture for mining norms from open source projects. It also discusses the opportunities presented by the domain of software repositories for the study of norms. In particular, it points towards how norms can be mined by leveraging and extending prior work in the areas of Normative Multi-Agent Systems (NorMAS) and mining software repositories.","2014","2025-04-25 15:28:57","2025-04-25 15:28:57","","26-39","","","8316","","","","Lecture Notes in Artificial Intelligence","","","","Special Interest Grp Agent Mining Interact and Integrat","","","","","","","","","ISSN: 0302-9743","","","","","","Cao, L; Zeng, Y; Symeonidis, AL; Gorodetsky, V; Muller, JP; Yu, PS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hence, information about the rate of diffusion could be useful to decision makers and support them in justifying their decisions. We study a variety of technology diffusion models and their application to OSS. Epidemic, Probit, and Bass models are compared on their interpretations of technology diffusion.

Generally, bugs are reported, fixed, verified and closed. However, in some cases bugs have to be re-opened. Re-opened bugs increase maintenance costs, degrade the overall user-perceived quality of the software and lead to unnecessary rework by busy practitioners. In this paper, we study and predict re-opened bugs through a case study on three large open source projects-namely Eclipse, Apache and OpenOffice. We structure our study along four dimensions: (1) the work habits dimension (e.g., the weekday on which the bug was initially closed), (2) the bug report dimension (e.g., the component in which the bug was found) (3) the bug fix dimension (e.g., the amount of time it took to perform the initial fix) and (4) the team dimension (e.g., the experience of the bug fixer). We build decision trees using the aforementioned factors that aim to predict re-opened bugs. We perform top node analysis to determine which factors are the most important indicators of whether or not a bug will be re-opened. Our study shows that the comment text and last status of the bug when it is initially closed are the most important factors related to whether or not a bug will be re-opened. Using a combination of these dimensions, we can build explainable prediction models that can achieve a precision between 52.1-78.6 % and a recall in the range of 70.5-94.1 % when predicting whether a bug will be re-opened. We find that the factors that best indicate which bugs might be re-opened vary based on the project. The comment text is the most important factor for the Eclipse and OpenOffice projects, while the last status is the most important one for Apache. These factors should be closely examined in order to reduce maintenance cost due to re-opened bugs.","2013-10","2025-04-25 15:28:57","2025-04-25 15:28:57","","1005-1042","","5","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This large amount of data hampers people to make sense of implicit links between software projects, e.g., dependencies, patterns, licenses. This context raises the question of what techniques and mechanisms can be used to help users and developers to link related pieces of information across software projects. In this paper, we propose a framework for a marketplace enhanced using linked open data (LOD) technology for linking software artifacts within projects as well as across software projects. The marketplace provides the infrastructure for collecting and aggregating software engineering data as well as developing services for mining, statistics, analytics and visualization of software data. Based on cross-linking software artifacts and projects, the marketplace enables developers and users to understand the individual value of components and their relationship to bigger software systems. Improved understanding creates new business opportunities for software companies: users will be able to analyze and compare projects, developers can increase the visibility of their products, and hosts may offer plugins and services over the data to paying customers.","2015","2025-04-25 15:28:57","2025-04-25 15:28:57","","3651-3660","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE Comp Soc; Univ Hawaii, Shidler Coll Business; Univ Hawaii, Dept EE; Univ Hawaii, Informat Sci Program; ONR; AFOSR; Natl Sci Fdn; IEEE Syst Sci & Cybernet Soc; ACM; SIAM; IEEE Hawaii Sect; IEEE Control Syst Soc; IEEE Grp Informat Theory; IEEE Grp Automat Control; ARO; Reg Med Program Hawaii; Univ Hawaii, Coll Business Adm; Nasdaq","","","","","","","","","ISSN: 1060-3425","","","","","","Bui, TX; Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While a number of studies proposed novel methods of representing expertise within individual projects, these methods are difficult to apply at an ecosystem level. However, with the focus of software development shifting from monolithic to modular, a method of representing developers' expertise in the context of the entire OSS development becomes necessary when, for example, a project tries to find new maintainers and look for developers with relevant skills. Aim: We aim to address this knowledge gap by proposing and constructing the Skill Space where each API, developer, and project is represented and postulate how the topology of this space should reflect what developers know (and projects need). Method: we use the World of Code infrastructure to extract the complete set of APIs in the files changed by open source developers and, based on that data, employ Doc2Vec embeddings for vector representations of APIs, developers, and projects. We then evaluate if these embeddings reflect the postulated topology of the Skill Space by predicting what new APIs/projects developers use/join, and whether or not their pull requests get accepted. We also check how the developers' representations in the Skill Space align with their self-reported API expertise. Result: Our results suggest that the proposed embeddings in the Skill Space appear to satisfy the postulated topology and we hope that such representations may aid in the construction of signals that increase trust (and efficiency) of open source ecosystems at large and may aid investigations of other phenomena related to developer proficiency and learning.","2021","2025-04-25 15:28:57","2025-04-25 15:28:57","","995-1007","","","","","","","International Conference on Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT","","","","","","","","","ISSN: 0270-5257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this, the generation of defect reports which reports the classes that are defective and computes the required software metrics is required. This process should be fully automated. Various data analysis research techniques and algorithms can be applied on this produced data set and this information can be very helpful for the developers and the organization as a whole for the prediction of bugs for future purposes and for analysis of the quality of the software being produced. The various issues addressed in this paper are (1) selection of suitable projects as input for the tool, (2) a mechanism to trace the whole project code history and identifying the classes present, (3) the criteria for classifying a class as defective, (4) method to generate most accurate software metrics for the classes, (5) combining all the data into a final representable format.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs. closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.","2015","2025-04-25 15:28:58","2025-04-25 15:28:58","","215-228","","","37","","","","Routledge Studies in Innovation Organization and Technology","","","","","","","","","","","","","","","","","","","Herstatt, C; Ehls, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help “transfer” their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more “open” and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as “porting,” the “kernel,” “copyleft,” and “forking” that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.","2012","2025-04-25 15:28:58","2025-04-25 15:28:58","","234-243","","3","71","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This dataset seeks to encourage the studies of OSS-wide copy-based reuse by providing copying activity data that captures whole-file reuse in nearly all OSS. To accomplish that, we develop approaches to detect copy-based reuse by developing an efficient algorithm that exploits World of Code infrastructure: a curated and cross referenced collection of nearly all open source repositories.

The methodology used in this research is modifiable for different purposes and is based on obtaining the best results from using open-source resources and knowledge of cartography. Lake Zebrus is an example how to perform accurate and state of the art bathymetric survey in a short time period. The area of Lake Zebrus is 417.57 ha. The lake has a small crooked coastline. Lake Zebrus has a maximum depth of 4.45 m and an average depth of 1.48 m. Results from the bathymetric survey can be used for further research based on depth data. The research tasks are accomplished as the methodology selected is repeatable in the other lakes. The research results prove that this methodology can be used for a bathymetric survey and it is possible to obtain high-definition results using open-source resources.","2020-11","2025-04-25 15:28:58","2025-04-25 15:28:58","","239-248","","3, SI","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since there is no central mechanism that governs the process of team formation, it is interesting to investigate if there are any significant correlations between project quality and the characteristics of the team members. However, for such analysis to be possible, we need good metrics of a project quality. This paper develops two such metrics, first one reflecting project's popularity, and the second one - the quality of support offered by team members to users.

Open source repositories typically contains vast amounts of information, much of it unstructured, meaning that even if a question has previously been discussed and dealt with it is not a trivial task to locate it. This can lead to rework and confusion amongst developers and possibly deter new developers from getting involved in the project in the first place. This paper will present the case for an open source software development ontology. Such an ontology would enable better categorization of information and the development of sophisticated knowledge portals in order to better organize community knowledge and increase efficiency in the open source development process.","2006","2025-04-25 15:28:58","2025-04-25 15:28:58","","65-75","","","203","","","","INTERNATIONAL FEDERATION FOR INFORMATION PROCESSING","","","","Int Federat Informat Proc, TC2 WG 2 13; COCOS; Gruppo Engn; AICA","","","","","","","","","ISSN: 1571-5736","","","","","","Damiani, E; Fitzgerald, B; Scacchi, W; Scotto, M; Succi, G","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, most existing community detection methods are designed for homogeneous networks, whereas the OSS ecosystem is a heterogeneous network. Therefore, we propose a meta-path-based method for heterogeneous community detection in the OSS ecosystem (METHODS). METHODS comprises four steps. Firstly, a heterogeneous information network is constructed based on meta-paths. Secondly, the Canopy algorithm is used to obtain the number of initial communities. Thirdly, the skip-gram model is used to identify seed nodes for community detection. Finally, METHODS detects heterogeneous communities around the seed nodes. By defining a series of evaluation metrics and verifying these on GitHub datasets, METHODS achieves the best performance of all the other methods. Moreover, the case studies on GitHub also shows METHODS can discover latent communities whose members are potentially relevant.","2023-10","2025-04-25 15:28:59","2025-04-25 15:28:59","","","","","162","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We aimed to develop an e-learning course to allow healthcare workers (HCWs) to learn these contents through a self-paced online format.Methods We developed an interactive hygiene training for HCWs of a tertiary care hospital using different content types of the HTML-5 package (H5P) plugin embedded into a Moodle-based learning management system. We evaluated the course using a short online questionnaire.Results We present various suitable topics for online hygiene trainings as well as their implementation in an e-learning course. Examples include content on hand hygiene indications and techniques, information on multidrug-resistant organisms and other current topics in infection control. HCWs reported high overall satisfaction, perceived increase in knowledge, practical relevance as well as good usability and comprehensibility.Discussion Currently available commercial and non-commercial hygiene trainings present a number of specific advantages but also drawbacks. The presented approach combines the advantages of both approaches. The majority of the presented content can be readily adapted to suit various hospitals and care facilities or serve as inspiration for creating similar courses while remaining cost-effective.Conclusion H5P course presentations are a low-threshold, cost-effective way to implement digital hygiene trainings in a wide variety of clinical settings.","2024-10-29","2025-04-25 15:28:59","2025-04-25 15:28:59","","","","4","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this purpose, it is becoming common to employ open-source microcontroller platforms, such as the Arduino. These boards and associated integrated software development environments provide affordable yet powerful solutions for the implementation of hardware control of transducers and acquisition of signals from detectors and sensors. It is, however, a challenge to write programs that allow interactive use of such arrangements from a personal computer. This task is particularly complex if some of the included hardware components are connected directly to the computer and not via the microcontroller. A graphical user interface framework, lnstrumentino, was therefore developed to allow the creation of control programs for complex systems with minimal programming effort. By writing a single code file, a powerful custom user interface is generated, which enables the automatic running of elaborate operation sequences and observation of acquired experimental data in real time.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs. closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.","2010-09","2025-04-25 15:28:59","2025-04-25 15:28:59","","248-256","","3","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such systems save a great deal of effort over ad hoc ways of advertising, packaging, and transmitting useful libraries, but coordination among project teams is still needed when one package makes a breaking change affecting other packages. Ecosystems differ in their approaches to breaking changes, and there is no general theory to explain the relationships between features, behavioral norms, ecosystem outcomes, and motivating values. We address this through two empirical studies. In an interview case study, we contrast Eclipse, NPM, and CRAN, demonstrating that these different norms for coordination of breaking changes shift the costs of using and maintaining the software among stakeholders, appropriate to each ecosystem's mission. In a second study, we combine a survey, repository mining, and document analysis to broaden and systematize these observations across 18 ecosystems. We find that all ecosystems share values such as stability and compatibility, but differ in other values. Ecosystems' practices often support their espoused values, but in surprisingly diverse ways.

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors (”problem solvers”) tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs (”problems”) tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between “core” and “peripheral” members identified exclusively on the basis of their individual level of contribution to the project.

This fact has motivated researchers to examine the factors that influence developers' intention to continue their participation. One factor is trust among developers. The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey.

These volunteers, commonly referred to as OSS project community, serve as the foundation of the OSS project, fostering its creation and sustenance and providing long-term support. The quality and sustainability of the OSS project is reliant upon the development and structure of the self-governing community. When a business organization plans to acquire an OSS solution, it not only takes into consideration the factors such as reliability, security, and scalability but also attaches significant importance to the likelihood of the OSS project being maintained and supported in the future so that it can rely on it as a stable and secure technology solution. Modern cloud-based software hosting platforms, such as GitHub, offer a range of options for automatically and freely accessing the complete development history of millions of OSS projects. This easy availability of detailed development history has enabled researchers to analyze and draw quantitative and scientific inferences about the quality of an OSS project which generally involves assessing three aspects, namely, software product, development process, and project community. With focus on project community part, a Framework for Assessment and Ranking of OSS Community is being presented in the current research work, following a detailed examination of the largest source code hosting and project collaboration platform, GitHub. Technique for Order of Preference by Similarity to Ideal Solution from Multi-Criteria Decision-Making toolkit has been utilized for assessing the quality of the project community. The framework has been validated by applying it on nine OSS projects and comparing the results with the outcomes obtained through an existing OSS evaluation methodology. The comparative analysis demonstrated that the proposed framework aligns with the aforementioned evaluation methodology while offering an opportunity for in-depth analysis on the dynamics of volunteer communities, which is lacking in previous evaluation methods. These insights can prove valuable for both potential adopters and project maintainers, aiding them in making informed strategic decisions. Framework for Project Community Assessment and Ranking follows a phased approach where first phase involves OSS project identification, second phase defines assessment criteria, in third phase data is fetched, stored and metrics are computed; and the last phase involves final Quality Assessment and Ranking. The framework will aid both corporate entities and individual practitioners in identifying an open source project with a robust volunteer community capable of producing a product of exceptional quality.image","2024-07","2025-04-25 15:28:59","2025-04-25 15:28:59","","","","7","36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, a common issue arises when incorporating third-party OSS accompanied with licenses, i.e., license incompatibility, which occurs when multiple licenses exist in one project and there are conflicts between them. Despite being problematic, fixing license incompatibility issues requires substantial efforts due to the lack of license understanding and complex package dependency. In this paper, we propose LiResolver, a fine-grained, scalable, and flexible tool to resolve license incompatibility issues for open source software. Specifically, it first understands the semantics of licenses through fine-grained entity extraction and relation extraction. Then, it detects and resolves license incompatibility issues by recommending official licenses in priority. When no official licenses can satisfy the constraints, it generates a custom license as an alternative solution. Comprehensive experiments demonstrate the effectiveness of LiResolver, with 4.09% false positive (FP) rate and 0.02% false negative (FN) rate for incompatibility issue localization, and 62.61% of 230 real-world incompatible projects resolved by LiResolver.

To alleviate this problem, we propose an approach to automatically generate repository tag based on a neural network and LDA by utilizing package dependencies and readme among OSS in communities. We design an algorithm for extracting the tag features of dependent OSS packages and build dependent feature vectors for OSS. We then combine the vectors with topic of OSS readme file as input to train the neural network and obtain the tag distribution probability of OSS, and subsequently, recommend tags for OSS.

We, first, analyze the general structure of the social networks, e.g., graph distances and the degree distribution of the social networks. Our social network structure analysis confirms a power-law degree distribution and small-world characteristics. However, the degree mixing pattern shows that high degree nodes tend to connect more with low degree nodes suggesting a collaboration between experts and newbie developers. We further conduct the same analysis on affiliation networks and find that contributors tend to participate in projects of similar team sizes. Second, we study the correlation between various social factors (e.g., closeness and betweenness centrality, clustering coefficient and tie strength) and the productivity of the contributors in terms of the amount of contribution and commitment to OSS projects. The analysis is conducted under the contexts of global and local networks, where a global network analysis considers a developer's connectivity in the whole OSS community network, whereas a local network analysis considers a developer's connectivity within a team network that is affiliated to a project. The analysis demonstrates evident influence of the social factors on the developers' overall productivity.","2015","2025-04-25 15:29:00","2025-04-25 15:29:00","","57-75","","","","","","","Lecture Notes in Social Networks","","","","","","","","","","","","","ISSN: 2190-5428 DOI: 10.1007/978-3-319-19003-7_4","","","","","","Kazienko, P; Chawla, N","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the high frequency of use of open source licenses, there has been little work about whether software developers understand the open source licenses that they use. To help understand whether or not developers understand the open source licenses they use, we conducted a survey that posed development scenarios involving three popular open source licenses (GNU GPL 3.0, GNU LGPL 3.0 and MPL 2.0) both alone and in combination. The 375 respondents to the survey, who were largely developers, gave answers consistent with those of a legal expert's opinion in 62% of 42 cases. Although developers clearly understood cases involving one license, they struggled when multiple licenses were involved. To understand the context in which licensing issues arise in practice, we analyzed real-world questions posed by developers about the three licenses considered in the survey on online question-and-answer communities. We also interviewed practicing developers about license interaction problems they have faced. Among several lessons, we learnt that licensing issues can constrain software evolution and that developers are cautious of more restrictive licenses. Our results indicate a need for tool support to help guide developers in understanding the structure of the code and the technical details of a project while taking into account the exact requirements imposed by the licenses involved.","2019-02","2025-04-25 15:29:00","2025-04-25 15:29:00","","211-239","","1","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Clinica aims for researchers to (i) spend less time on data management and processing, (ii) perform reproducible evaluations of their methods, and (iii) easily share data and results within their institution and with external collaborators. The core of Clinica is a set of automatic pipelines for processing and analysis of multimodal neuroimaging data (currently, T1-weighted MRI, diffusion MRI, and PET data), as well as tools for statistics, machine learning, and deep learning. It relies on the brain imaging data structure (BIDS) for the organization of raw neuroimaging datasets and on established tools written by the community to build its pipelines. It also provides converters of public neuroimaging datasets to BIDS (currently ADNI, AIBL, OASIS, and NIFD). Processed data include image-valued scalar fields (e.g., tissue probability maps), meshes, surface-based scalar fields (e.g., cortical thickness maps), or scalar outputs (e.g., regional averages). These data follow the ClinicA Processed Structure (CAPS) format which shares the same philosophy as BIDS. Consistent organization of raw and processed neuroimaging files facilitates the execution of single pipelines and of sequences of pipelines, as well as the integration of processed data into statistics or machine learning frameworks. The target audience of Clinica is neuroscientists or clinicians conducting clinical neuroscience studies involving multimodal imaging, and researchers developing advanced machine learning algorithms applied to neuroimaging data.","2021-08-13","2025-04-25 15:29:00","2025-04-25 15:29:00","","","","","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. Methods: This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Observations: Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Conclusion: Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future. The impact of these new technologies is particularly effective in image communication, PACS and teleradiology. (C) 2010 Elsevier Ireland Ltd.

Open Source Software (OSS) projects have been an alternative to support education in Software Engineering, as they allow contact with real development projects and environments. However, the adoption of these projects in the classroom presents some obstacles, such as choosing the appropriate project, and the time and effort needed to prepare the classes and get used to the open source environment. In order to reduce the difficulties faced by instructors, we are working on developing a portal to catalog worked examples extracted from OSS projects to assist instructors. In this paper, we present the first steps towards creating this catalog, which is creating a pattern for guiding the structuring the worked examples. We are applying the Design Science Research paradigm. The activities reported in this paper regards the first Design Cycle, and were divided into three stages related to the elaboration and evaluation of the pattern for cataloging the worked examples. In these stages, we carried out focus groups and interviews with Software Engineering instructors, including the instantiation of the pattern to catalog actual worked examples. After each stage, we had a new and improved version of the pattern for cataloging the worked examples. Such pattern served as a basis to create the first version of the worked examples portal, which will be evaluated in the next stages of the research.","2020","2025-04-25 15:29:00","2025-04-25 15:29:00","","493-498","","","","","","","","","","","Univ Fed Rio Grande Norte; UERN; Loggi; Google; Conselho Nacl Desenvolvimento Cientifico & Tecnologico; Software Engn Team Res & Innovat; Inst Metropole Digital; UFRN, DIMAP","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The key project mission is to liberate scientific climate data, making it equitable and freely accessible to everyone. The #semantic Climate community achieves this through two central activities, namely collaborative open notebook science, and citizen engagement. The first activity is research oriented and involves creation of a proof-of-concept software toolkit that uses AI over NLP to transform locked literature (such as PDF documents) into semantic, hypermedia form. This is a non-trivial task, that has haunted developers for over three decades, and the #semantic Toolkit makes complex climate reports not just easily accessible, but also processable by machines, embedded in the Global Knowledge Graph and thereby connected to multilingual resources. The second activity is where the #semantic Climate community engages citizens in climate action and awareness through interactive hackathons, open and transparent working practices, and using Git versioning. From a citizen science perspective, this includes designing community outreach activities (games), giving attribution to all participants, and engaging the wider public in the culture and practices of science (verifiable knowledge, review, data science, modern infrastructure use, etc). This article is an overview of the #semantic Climate community building efforts, and how the project employs strategies, techniques, and ideas from the fields of Open Notebook Science.

The stability and longevity of this group of most active developers are crucial for the success of the project. While there has been prior work on identifying key individuals in open source development, little attention has been devoted to the identification of cross-cutting core individuals (boundary spanners) whose responsibilities span across different functional areas of open source development (e.g., who are involved both in development-centric activities and user-centric activities). To address this gap, we propose an approach to identify the core cross-cutting members and their roles within the community through analyzing email communication repositories. We use Social Network Analysis (SNA) tools to identify the most active core members in different forums (that have different focus such as Python-dev that focuses on language evolution and Python Lists that focus on user support), and their activities over time, thus identifying the core developers and their involvement in different community mailing lists. Based on the involvement of a core developer and the overall social structure of the network of core developers, we also present an approach for identifying a potential replacement for a community administrator that steps down. Using email repositories of six main Python forums as the case study domain, we computed several social network analysis metrics to characterize the core developers and their importance in the Python community.","2017","2025-04-25 15:29:01","2025-04-25 15:29:01","","308-317","","","","","","","Asia-Pacific Software Engineering Conference","","","","","","","","","","","","","ISSN: 1530-1362","","","","","","Lv, J; Zhang, H; Hinchey, M; Liu, X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine how projects engage in distinct “discursive modulation practices” to imprint the community's shared core doctrines and design principles onto the software thereby shaping its novelty and complexity. We borrow the concept of modulation from audio synthesis to explain how a preexisting signal-in our case, the ongoing community discourse-is modulated to produce varying sounds-in our case, the novelty and complexity of the software. The concept of modulation offers a lens to understand how emergent, community-wide development activities are influenced by filtering discursive positions and mixing those positions, thereby shaping the artifact's novelty and complexity. Our research shows that the modulation of novelty exhibits a range from “proximal” to “distal” searches for new features, while the modulation of complexity varies between “integration” and “deprecation.” By drawing on these concepts, we formulate a theory that explains how modulation results in alternative OSS community approaches to shaping software novelty and complexity and how this process reflects and is reflected in the resulting software artifact.","2024-12","2025-04-25 15:29:01","2025-04-25 15:29:01","","1395-1422","","4","48","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The metadata about a change includes a change message to record the intention of the change. Classification of changes, based on change messages, into different change types has been explored in the past to understand the evolution of software systems from the perspective of change size and change density only. However, software evolution analysis based on change classification with a focus on change evolution patterns is still an open research problem. This study examines change messages of 106 OSS projects, as recorded in the git repository, to explore their evolutionary patterns with respect to the types of changes performed over time. An automated keyword-based classifier technique is applied to the change messages to categorize the changes into various types (corrective, adaptive, perfective, preventive, and enhancement). Cluster analysis helps to uncover distinct change patterns that each change type follows. We identify three categories of 106 projects for each change type: high activity, moderate activity, and low activity. Evolutionary behavior is different for projects of different categories. The projects with high and moderate activity receive maximum changes during 76-81 months of the project lifetime. The project attributes such as the number of committers, number of files changed, and total number of commits seem to contribute the most to the change activity of the projects. The statistical findings show that the change activity of a project is related to the number of contributors, amount of work done, and total commits of the projects irrespective of the change type. Further, we explored languages and domains of projects to correlate change types with domains and languages of the projects. The statistical analysis indicates that there is no significant and strong relation of change types with domains and languages of the 106 projects.","2018-12","2025-04-25 15:29:01","2025-04-25 15:29:01","","1105-1124","","6","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The case study consisted of semi-structured interviews with the participants involved in the migration. The interviews centered on the contribution of stakeholder collaboration during the software migration using a boundary critique. The results suggest that stakeholder collaboration can contribute to open source software migration. From a managerial perspective, business leaders must understand the value of stakeholder collaboration in open source software migration. Boundary critique can be an important tool for achieving broader collaboration of stakeholders.","2013","2025-04-25 15:29:01","2025-04-25 15:29:01","","194-208","","","","","","","","","","","","","","","","","","","","DOI: 10.4018/978-1-4666-2151-0.ch012","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These techniques show promise for applications such as structural health monitoring. However, video-based approaches to measuring structural dynamics are not as sensitive as on-contact sensor-based techniques. Furthermore, because video-based techniques involve capturing a 2D perspective projection of the 3D environment, there is an added complication in extracting calibrated quantitative measurements from these systems. In many applications, it would be advantageous to deploy networks, or arrays of imagers for monitoring large-scale infrastructure from different perspectives. Often, computer vision techniques, such as multi-view stereo, benefit from knowledge of the position and orientation of the cameras. Unfortunately, accurately knowing this information can lead to increased setup costs. Furthermore, it is not always clear what arrangement of cameras would be sufficient for any given infrastructure monitoring applications. In addition, the performance of arrays of imagers is affected by factors such as lighting conditions and weather. There may also be significant restrictions on the physical locations where imagers are allowed to be placed. For these reasons, it is advantageous to have tools to aid in the design and development of imager-based sensor networks for structural dynamics applications. In this work, we demonstrate the use of open-source computer graphics software for simulating the behavior of imagers observing dynamic structures. We demonstrate the ability to use these tools to plan the deployment of imager-based sensor networks to rapidly test and develop algorithms and techniques for video-based structural dynamics.","2024","2025-04-25 15:29:01","2025-04-25 15:29:01","","19-26","","","","","","","Conference Proceedings of the Society for Experimental Mechanics Series","","","","Soc Expt Mech","","","","","","","","","ISSN: 2191-5644","","","","","","DiMaio, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects.","2024-05","2025-04-25 15:29:01","2025-04-25 15:29:01","","","","5","36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thus the existing software systems must evolve to conform to these requirements. The model which currently address this kind of concern is SOA (Service Oriented Architecture). This article deals with the reuse of ADempiere within the framework of the implementation of a service oriented ERP. To operate the migration of the existing code, firstly we reconstituted the architecture of this ERP. This operation made it possible to acquire the technical knowledge necessary to develop services by injection of dependence. The new software resulting from this operation distinctly separates the presentation tier from the back-end. The back-end tier exposes a set of Web services which encapsulates the code of ADempiere. These services can either be in a synchronous way throughout the Spring XFire technology, or in an asynchronous way through Apache ActiveMQ technology.","2009","2025-04-25 15:29:01","2025-04-25 15:29:01","","33-38","","","","","","","","","","","Networked European Software & Serv Initiative","","","","","","","","","","","","","","","Boness, K; Fernandes, JM; Hall, JG","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This issue is worsened by the scarcity of cybersecurity professionals. Moreover, the specialization required for cybersecurity expertise is both costly and time-consuming. In light of these challenges, this study has concentrated on automating cybersecurity processes, particularly those pertaining to continuous vulnerability detection. A cybersecurity vulnerability scanner was developed, which is freely available to the community and does not necessitate any prior expertise from the operator. The effectiveness of this tool was evaluated by IT companies and systems engineers, some of whom had no background in cybersecurity. The findings indicate that the scanner proved to be efficient, precise, and easy to use.

While a large body of studies focuses on the importance of developers' reputations in their participation motivations, there is still lack of understanding for two issues. First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

Although this strategy has clear benefits, it does not place enough care in training students to face complex, non-trivial legacy software projects. To bridge this gap, novel SE courses are leveraging the rich variety of open-source software (OSS) projects to illustrate how these methodologies and concepts are applied to existing, non-trivial software systems. To better understand the benefits, challenges, and opportunities of this transition, in this paper, we interview seven SE professors that changed their academic setting to aspire students to comprehend, maintain, and evolve OSS systems as part of their SE course. We found that there are different ways to make use of OSS projects in SE courses in terms of project choice, assessment, and learning goals. Moreover, we evidence clear benefits of this approach, including improving students' social and technical skills, and helping students enhancing their resume. Also, we observed that this strategy comes with costs: the activity demands effort and time from the professor and the barrier for one getting involved with and, therefore, placing a meaningful contribution, in an OSS community is often high.","2017","2025-04-25 15:29:01","2025-04-25 15:29:01","","117-121","","","","","","","Conference on Software Engineering Education and Training","","","","IEEE; Reliability Soc; Armstrong State Univ","","","","","","","","","ISSN: 1093-0175","","","","","","Washizaki, H; Mead, N","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software, however, is increasingly developed in open source software (OSS) forms which have several unique characteristics. In this study, we approach OSS RE as a sociotechnical, distributed cognitive process where distributed actors “compute” requirements- i.e., transform requirements-related knowledge into forms that foster a shared understanding of what the software is going to do and how it can be implemented. Such computation takes place through social sharing of knowledge and the use of heterogeneous artifacts. To illustrate the value of this approach, we conduct a case study of a popular OSS project, Rubinius-a runtime environment for the Ruby programming language-and identify ways in which cognitive workload associated with RE becomes distributed socially, structurally, and temporally across actors and artifacts. We generalize our observations into an analytic framework of OSS RE, which delineates three stages of requirements computation: excavation, instantiation, and testing-in-the-wild. We show how the distributed, dynamic, and heterogeneous computational structure underlying OSS development builds an effective mechanism for managing requirements. Our study contributes to sorely needed theorizing of appropriate RE processes within highly distributed environments as it identifies and articulates several novel mechanisms that undergird cognitive processes associated with distributed forms of RE.","2018","2025-04-25 15:29:01","2025-04-25 15:29:01","","1217-1252","","12","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results show that the new setup may provide core GSE challenges as well as challenges associated with software development outsourcing and challenges related to working on large open source software. The present article compares the experiences gained from running a combined GSE and OSSD course against the experiences gained from running a traditional GSE course. The two alternatives are compared in terms of students' learning outcomes and course organization. The authors found that a combined GSE and OSSD course provides learning opportunities that are partly overlapping with, and partly complementary to, a traditional GSE course. The authors also found that the combined OSSD and GSE course was somewhat easier to organize because most of the activities took place in a single university setting. The authors used the extended GSE taxonomy for the comparison and found it to be a useful tool for this, although it had some limitations in expressive power. Therefore, two additional relationship dimensions are proposed that will further enrich the extended taxonomy in classifying GSE (and OSSD) projects.","2019-02","2025-04-25 15:29:01","2025-04-25 15:29:01","","","","2, SI","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual developers contribute to developing the software, but do not hold the copyright to appropriate its value. This raises questions regarding motives behind such effort. We provide an integrated model of developers' incentives to describe OSS development and compare restrictive OSS licenses that force all modifications to be kept open with non-restrictive OSS licenses that allow proprietary ownership of modified works. Different incentives govern effort provision at different stages of the software development process. We show that open-source licenses can provide socially valuable software when a proprietary license fails to do so. We also show that restrictive OSS licenses generate greater effort provision in the design stage of software development relative to non-restrictive licenses. Endogenizing licensing choice, we find that a project leader chooses a non-restrictive OSS license if reputational concerns drive developers' incentives, a proprietary license when there is a large population of users in the market and a restrictive OSS license if user population is small but reputational benefit is high. Our results resonate well with empirical findings and suggest additional testable implications about the relationship between licensing and software project characteristics.

Mass-market consumers can be divided between those who are informed about the existence of OSS and those who are uninformed. Since OSS producers have little incentive to advertise, there may be a substantial mass of uniformed consumers, leading to market failures that may justify government intervention. We study three government policies: (a) mandated adoption, whereby the government forces public agencies, schools, and universities to adopt OSS, (b) information provision, whereby the government informs the uninformed users about the existence and the characteristics of OSS, and (c) subsidy, whereby the government makes a payment to consumers if they adopt OSS. We show that mandated adoption and information provision may increase social welfare, but the subsidy always reduces it. When network externalities are added to the model, we show that mandated adoption and information provision may increase social welfare if they help the market to tip towards standardization.","2005-03","2025-04-25 15:29:02","2025-04-25 15:29:02","","217-240","","2","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The focus of the project has been on managing the evolution of Free and Open Source Software distributions. Evolution of these distributions is realized through the upgrade, the addition, and the removal of software packages. The project has two main objectives: (i) develop a model-based approach to safely support the upgrade of FOSS systems, (ii) develop better algorithms and tools to plan upgrade paths based on various information sources about software packages and on optimization criteria. The paper focuses on the first objective of the project. The main result of this objective is an approach that promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e. g., configuration incoherences) and dynamic aspects (e. g., the execution of configuration scripts) are taken into account, improving over the state of the art of package managers.","2013","2025-04-25 15:29:02","2025-04-25 15:29:02","","56-63","","","8166","","","","Lecture Notes in Computer Science","","","","","","","","","","","","","ISSN: 0302-9743","","","","","","Gorbenko, A; Romanovsky, A; Kharchenko, V","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The complexity of today's opensource supply chains results in a significant attack surface, giving attackers numerous opportunities to reach the goal of injecting malicious code into open-source artifacts that is then downloaded and executed by victims. This work proposes a general taxonomy for attacks on opensource supply chains, independent of specific programming languages or ecosystems, and covering all supply chain stages from code contributions to package distribution. Taking the form of an attack tree, it covers 107 unique vectors, linked to 94 realworld incidents, and mapped to 33 mitigating safeguards. User surveys conducted with 17 domain experts and 134 software developers positively validated the correctness, comprehensiveness and comprehensibility of the taxonomy, as well as its suitability for various use-cases.

We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects. (C) 2013 Elsevier B.V.

In this paper, we explore how to measure trust in open source supply chains with the goal of developing robust measures for trust based on the behaviors of developers in the community. To this end, we contribute a process for decomposing trust in a complex large-scale system into key trust relationships, systematically identifying behavior-based indicators for the components of trust for a given relationship, and in turn operationalizing data-driven metrics for those indicators, allowing for the wide-scale measurement of trust in practice.","2024","2025-04-25 15:29:02","2025-04-25 15:29:02","","57-61","","","","","","","","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our analysis aims at determining and discussing patterns of failure occurrences in the three OSS products to be used to predict reliability behaviour of future releases. Our findings indicate that in the three cases, failures occurrences follow a predetermined pattern, which shows: a) an initial stage in which the community learns the new version b) after this first period a rapid increase of the failure detection rate until c) very few failures are left and the discovery of a new failure discovery is rare. This is the stage in which the version can be considered reliable.","2010","2025-04-25 15:29:03","2025-04-25 15:29:03","","268-280","","","319","","","","IFIP Advances in Information and Communication Technology","","","","Int Federat Informat Proc Work Grp 2 13","","","","","","","","","ISSN: 1868-4238","","","","","","Agerfalk, P; Boldyreff, C; GonzalezBarahona, JM; Madey, GR; Noll, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, newcomers face many barriers when making their first contribution, leading in many cases to dropouts. Due to the collaborative nature of community-based OSS projects, newcomers may be susceptible to social barriers, such as communication breakdowns and reception issues. In this article, we report a two-phase study aimed at better understanding social barriers faced by newcomers. In the first phase, we qualitatively analyzed the literature and data collected from practitioners to identify barriers that hinder newcomers' first contribution. We designed a model composed of 58 barriers, including 13 social barriers. In the second phase, based on the barriers model, we developed FLOSScoach, a portal to support newcomers making their first contribution. We evaluated the portal in a diary-based study and found that the portal guided the newcomers and reduced the need for communication. Our results provide insights for communities that want to support newcomers and lay a foundation for building better onboarding tools. The contributions of this paper include identifying and gathering empirical evidence of social barriers faced by newcomers; understanding how social barriers can be reduced or avoided by using a portal that organizes proper information for newcomers (FLOSScoach); presenting guidelines for communities and newcomers on how to reduce or avoid social barriers; and identifying new streams of research.","2019-04","2025-04-25 15:29:03","2025-04-25 15:29:03","","247-290","","1-2","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adopt Husted and Michailova's model on dual allegiance and knowledge sharing in inter-firm R&D collaborations to the context of open source software firms. We argue that the type of allegiance the individual holds towards their employing firm and the open source community has a strong influence of how they share knowledge with other community members. We use the examples of two open source software firms in New Zealand to ground the empirical inspiration of our paper and to illustrate our key ideas and arguments. We discuss the knowledge governance challenges imposed by employees' dual allegiance and how managers of open source software firms can balance the demands of the open source community and the interests of the clients.","2010-09","2025-04-25 15:29:03","2025-04-25 15:29:03","","314-326","","3","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Communications and collaborations are essential for the success of projects. Usually, the most active and productive programmers are awarded with promotion to developers. To more effectively manage and progress the projects, it is important and beneficial to rank the programmers and thus, predict the developer candidates. In this work, we propose to combine machine learning techniques with existing complex network node ranking algorithms to improve the prediction results. Specifically, we have made the following contributions: (1), we have designed a novel machine learning-based classifier with significantly improved prediction performance; (2), we have constructed and tested various networks built based on the programmer email communication information; and (3), we have used real-world project data to compare different techniques and validate our methods. Experimental results demonstrate that our technique reduces the error rate by 25% compared with the second best. Moreover, we discover that the KK nearest neighbor (KNN)-based machine learning algorithm and non-directional temporal network with a time window of 1-3 months give the best prediction results.","2018-06","2025-04-25 15:29:03","2025-04-25 15:29:03","","845-868","","6","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Altmetrics cannot be confined to traditional measurable indicators. That the importance of the open source software used, and its position in the online community is itself a strong measure for academic impact and success, which is all too often overlooked in research. The research can also conclude that the multiplexing of software online, through the citation of a citation, ultimately leads to an online peered review system within the community, effectively developing and maintaining through open use software itself.

Therefore, researchers and OSS projects have proposed strategies to label tasks (a.k.a. issues). Several approaches relying on machine learning techniques, historical information, and textual analysis have been submitted. However, the results vary, and these approaches are still far from mainstream adoption, possibly because of a lack of good predictors. Inspired by previous research, we advocate that the prediction models might benefit from leveraging social metrics. In this research, we investigate how to assist the new contributors in finding a task when onboarding a new project. To achieve our goal, we predict the skills needed to solve an open issue by labeling them with the categories of APIs declared in the source code (API-domain labels) that should be updated or implemented. Starting from a case study using one project and an empirical experiment, we found the API-domain labels were relevant to select an issue for a contribution. In the sequence, we investigated employing interviews and a survey of what strategies maintainers the strategies believe the communities have to adopt to assist the new contributors in finding a task. We also studied how maintainers think about new contributors' strategies to pick a task. We found maintainers, frequent contributors, and new contributors diverge about the importance of the communities and new contributors' strategies. The ongoing research works in three directions: 1) generalization of the approach, 2) Use of conversation data metrics for predictions, 3) Demonstration of the approach, and 4) Matching contributors and tasks skills. By addressing the lack of knowledge about the skills in tasks, we hope to assist new contributors in picking tasks with more confidence.","2023","2025-04-25 15:29:04","2025-04-25 15:29:04","","311-313","","","","","","","Proceedings of the IEEE-ACM International Conference on Software Engineering Companion","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; Melbourne Convent Bur; State Govt Victoria; CSIRO; Huawei; Monash Univ; Meta; Google; AWS; Monash Univ; Dragon Testing Technol; IBM; Univ Melbourne; RMIT Univ","","","","","","","","","ISSN: 2574-1926","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To do this, I begin by striking a dialectic between John Milbank's theological and David Graeber's anthropological conceptions of gift economies, illuminating crucial aspects of each to uncover what alternative economic principles are applicable to standard capitalist economic ideologies. I then turn to a practical application of where these gift economy ideologies are already being utilized to a degree, arguing specifically that open source software provides an alternative economic logic for countless members of the technology sector. On a broad level, I hope to show that capitalism provides the means to alter itself within its own ethos, as certain economic ideologies like gift economies - could potentially assuage those economic models that contribute to economic inequality. By accentuating these alternative logics within technology firms, they can be expanded and made more substantial, subsequently altering capitalism from the inside out.","2017","2025-04-25 15:29:04","2025-04-25 15:29:04","","5-21","","1","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study aims at providing an overview of the current practice of OpenMP usage in open source projects. We focus our study on the considerations necessary for efficient OpenMP usage, as parallelizing an application with OpenMP comes with a certain overhead necessary for thread creation and management. For this purpose, we developed a binary analysis tool that automatically estimates the complexity of a parallel region allowing a comparison with the complexity of thread creation and management overhead in bluk. We applied this tool on a large set of 537 open source applications. Specifically, we want to answer the question: “To what extent is the usage of OpenMP in general following known good practices from the HPC community?” In particular, we find that 45% of projects contain at least one example of a rather simple parallel region. In these cases, it is questionable whether parallelization is worth the overhead necessary for thread creation and management. We also observe from the codes analysed that the style of using OpenMP apparently did not change over the last decade.

However, current FRAP/iFRAP analysis methods suffer from simplified assumptions about sample geometry, bleaching/photo-conversion inhomogeneities, and the underlying reaction-diffusion kinetics. To address these shortcomings, we developed the software PyFRAP, which fits numerical simulations of three-dimensional models to FRAP/iFRAP data and accounts for bleaching/photoconversion inhomogeneities. Using PyFRAP we determined the diffusivities of fluorescent molecules spanning two orders of magnitude in molecular weight. We measured the tortuous effects that cell-like obstacles exert on effective diffusivity and show that reaction kinetics can be accounted for by model selection. These applications demonstrate the utility of PyFRAP, which can be widely adapted as a new extensible standard for FRAP analysis.","2018-04-20","2025-04-25 15:29:04","2025-04-25 15:29:04","","","","","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding the type of residual bugs is fundamental for adopting proper countermeasures in current and future software releases. Depending on the fault triggering conditions that lead to a failure, developers can introduce fault-tolerance mechanisms and plan verification and validation strategies.

However, while there is no shortage on research on individuals' motivation for contributing to open source, few have investigated the commercial companies' motivations for doing the same. A case study was conducted at three different companies from the IT service industry, to investigate three possible drivers: sale of complimentary services, innovation and opensourcing (outsourcing). We offer three conclusions. First, we identified three main drivers for contributing to open source, which are (a) selling complimentary services, (b) building greater innovative capability and (c) cost reduction through opensourcing to an external community. Second, while previous research has documented that the most important driver is selling complimentary services, we found that this picture is too simple. Our evidence points to a broader set of motivations, in the sense that all our cases exhibit combinations of the three drivers. Finally, our findings suggest that there might be a shift in how commercial companies view open source software. The companies interviewed have all expressed a moral obligation to contribute to open source. (C) 2011 Elsevier Ltd.

To validate such claims, researchers have conducted case studies of “successful” open source development projects. This case study of the FreeBSD project provides further understanding of open source development. The FreeBSD development process is fairly well-defined with proscribed methods for determining developer responsibilities, dealing with enhancements and defects, and for managing releases. Compared to the Apache project, FreeBSD uses a smaller set of core developers that implement a smaller portion of the system, and uses a more well-defined testing process. FreeBSD and Apache have a similar ratio of core developers to (1) people involved in adapting and debugging the system, and (2) people who report problems. Both systems have similar defect densities, and the developers are also users in both systems.","2004","2025-04-25 15:29:04","2025-04-25 15:29:04","","96-105","","","","","","","","","","","IEEE Comp Soc, TCSE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS/FS alternatives complicate an already complex information goods market plagued by piracy concerns. Although producer perspectives on software pricing and piracy controls have been addressed extensively, consumers' perspective and willingness to pay for commercial software is not very well understood. This paper empirically determines willingness to pay for a leading commercial software application (Microsoft Office) in the presence of an OSS/FS alternative. A contingent valuation approach is used to elicit willingness to pay for the application. The research design employs a 2 x 2 x 2 experiment to investigate the impact of preventive control, deterrence control, and OSS/FS alternative. The results indicate that the availability of an OSS/FS alternative has little impact on willingness to pay for Microsoft Office.

Compared with the prevailing proprietary approaches, open-source software products are developed by co-opting external developers and prospective users. Although a core group of developers might still play a key role in the initial design and development, a notable aspect of the open-source software paradigm is the role of peripheral developers in the enhancement and popularization of the product. Peripheral developers are not formal members of the core development team. They voluntarily contribute their time and creative talent in improving the quality of the product or in popularizing the product through word-of-mouth advocacy. As volunteers, they are not subject to the traditional hierarchical controls, nor are they contractually obligated. Peripheral developers represent a novel and unique aspect of open-source software development, and there is a greater interest in tapping their potential. However, there has been limited evidence about how and when their participation has beneficial impacts. We examine how peripheral developers contribute to product quality and diffusion by utilizing longitudinal data on 147 open-source software products. Hierarchical linear modeling analysis indicates that peripheral developers make significant contributions to product quality and diffusion, especially on projects that are in the more mature stages of product development.","2012-03","2025-04-25 15:29:05","2025-04-25 15:29:05","","144-163","","1","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In recent years, firms motivated by revenues from software services markets have become the primary contributors to open-source development. In this paper we study the role of services in open source software development and explore the choice between open source and proprietary software. Specifically, our economic model jointly analyzes the investment and pricing decisions of the originators of software and of subsequent open-source contributors. We find that if a contributor is efficient in software development, the originator should adopt an open-source strategy, allowing the contributor to offer higher total quality and capture the higher end of the market while the originator focuses on providing software services to lower end consumers. Conversely, if the contributor is not efficient in development, the originator should adopt a proprietary software development strategy, gaining revenue from software sales and squeezing the contributor out of the services market. In certain cases an increase in originator development efficiency can result in increased contributor profits. Finally, we find that, somewhat counterintuitively, an increase in contributor development efficiency can reduce overall social welfare.","2013-12","2025-04-25 15:29:05","2025-04-25 15:29:05","","1068-1086","","4","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As an example, software used to determine whether a user has appropriate security clearance might be scattered throughout the many modules, which require this check. Utilising AOP, “aspects” are “woven” into the software either in a “static” method, during compilation, or a “dynamic” method while the program is executing. The “join points” in a program are the points where these aspects are applied. The “aspect” code is written once and “woven” in to the modules at join points. Typical aspects involve logging changes to a database and monitoring memory usage. Our focus is on aspects related to security and intrusion incident detection. Dynamic weaving allows aspects to be woven in and out as the program is executing. However the base code often must be compiled with additional “syntactic sugar” - additions that are required for the later connection of dynamic aspects. This paper presents a new technique to enable dynamically loaded security modules to be added into existing C/C++ code on the fly while the program is executing. Our tool is a Run-Time Event Monitoring System called “dynamicHook”, implemented on a standard Linux platform using existing Linux tools, which tests each potential join point for the required activation of advice. Our system does not need to modify the executable files, but instead we compile in special “linkage” between the base code and potential aspects which are then called as dynamically linked routines located in shared libraries. Our scheme does not require any new syntax or language extensions or rely on code transformations; we thus use it for adding intrusion detection methodologies to pre-existing off-the-shelf open source software.","2007","2025-04-25 15:29:05","2025-04-25 15:29:05","","147-154","","","","","","","","","","","","","","","","","","","","","","","","","","Armistead, L","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. Design/methodology/approach - The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. Findings - The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain. Last, but not least, it blurs the boundary between development and use, since the developer remains the key user. Research limitations/implications - The paper addresses the implications for future research in the area. Practical implications - The paper addresses implications for practitioners directly involved in innovation and product development. Originality/value - This paper develops a conceptual framework for understanding product development based on non-proprietary knowledge, which cannot be adequately accounted for by traditional corporate innovation theory alone.","2008","2025-04-25 15:29:05","2025-04-25 15:29:05","","142+","","1","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Fusing and organizing many different ideas, opinions, and interpretations into a coherent and acceptable plan or project evaluation is challenging. This is especially true when seeking contributions from a large number of participants, especially when not all can participate in group discussions, or when some prefer to contribute their perspectives anonymously. One of the major breakthroughs in the area of evaluation and program planning has been the use of graphical tools to represent the brainstorming process. This provides a quantitative framework for organizing ideas and general concepts into simple-to-interpret graphs. We developed a new, open-source concept mapping software called R-CMap, which is implemented in R. This software provides a graphical user interface to guide users through the analytical process of concept mapping. The R-CMap software allows users to generate a variety of plots, including cluster maps, point rating and cluster rating maps, as well as pattern matching and go-zone plots. Additionally, R-CMap is capable of generating detailed reports that contain useful statistical summaries of the data. The plots and reports can be embedded in Microsoft Office tools such as Word and PowerPoint, where users may manually adjust various plot and table features to achieve the best visual results in their presentations and official reports. The graphical user interface of R-CMap allows users to define cluster names, `change the number of clusters, select rating variables for relevant plots, and importantly, select subsets of respondents by demographic criteria. The latter is particularly useful to project managers in order to identify different patterns of preferences by subpopulations. R-CMap is user-friendly, and does not require any programming experience. However, proficient R users can add to its functionality by directly accessing built-in functions in R and sharing new features with the concept mapping community. (C) 2016 Elsevier Ltd.

What type of knowledge is lost and how knowledge loss impacts the productivity of the FLOSS contributors that remain in a project is not known. Further, little is known about the barriers associated with the re-acquirement of lost knowledge types. There are many open questions, such as what are best practices and guidelines to retain knowledge lost by type while considering the relevant barriers. The main contribution of my research will be to provide an understanding of what type of knowledge is lost and its impact on the productivity of the contributor. Best practices and guidelines will also be contributed to retain knowledge lost by type and will be evaluated in FLOSS communities for their effectiveness.","2016","2025-04-25 15:29:06","2025-04-25 15:29:06","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our brief review on free and open source software (FOSS) packages points out the existence of software offering a wide range of functionality, all the way from approximate semiempirical calculations with tight-binding density functional theory to sophisticated ab initio wave function methods such as coupled-cluster theory, covering both molecular and solid-state systems. Combined with the remarkable increase in the computing power of personal devices, which now rivals that of the fastest supercomputers in the world in the 1990s, we demonstrate that a decentralized model for teaching computational chemistry is now possible thanks to FOSS packages, enabling students to perform reasonable modeling on their own computing devices in the bring your own device (BYOD) scheme. FOSS software can be made trivially simple to install and keep up to date, eliminating the need for departmental support, and also enables comprehensive teaching strategies, as various algorithms' actual implementations can be used in teaching. We exemplify what kinds of calculations are feasible with four FOSS electronic structure programs, assuming only extremely modest computational resources, to illustrate how FOSS packages enable decentralized approaches to computational chemistry education within the BYOD scheme. FOSS also has further benefits driving its adoption: the open access to the source code of FOSS packages democratizes the science of computational chemistry, and FOSS packages can be used without limitation also beyond education, in academic and industrial applications, for example.

In turn, specifying and evaluating OSS quality has become a significant challenge for OSS adoption in organizations that are inclined to use them. Although many OSS quality models have been proposed in the literature, the dynamic and diverse nature of OSS has caused these models to be heterogeneous in terms of structure and content. This has adversely affected the standardization of evaluations and led to the evaluation results obtained from different OSS quality models for the same purpose being incomparable and sometimes unreliable. Therefore, in this study, a meta-model for OSS quality (OSS-QMM), which employs a unified structure from existing quality models and enables the derivation of homogeneous models, has been proposed. For this purpose, a systematic and laborious effort has been spent via a step-based meta-model creation process including review-and-revise iterations. In order to validate the OSS-QMM, case study and expert opinion methods have been applied to answer three research questions (RQs) targeted to investigate practical applicability, results comparability, and effectiveness of using the meta-model. Multiple and embedded case study designs have been employed for evaluating three real ERP systems, and 20 subject matter experts have been interviewed during the validation process. The results of multi-faceted empirical studies have indicated that the OSS-QMM has addressed solving problems in OSS quality evaluation and its adoption with high degrees of confidence.","2024-06","2025-04-25 15:29:06","2025-04-25 15:29:06","","487-541","","2","32","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A virtual social network is therefore formed through a mailing list, in which, each subscriber could be a node of the network, and the communications (email messages) could be the links of the network. Due to the virtual property of this network, physical (geographical) distance between network nodes is usually considered irrelevant. Instead, what is more important is the conceptual distance that captures the key properties of this virtual network. This paper studies the open-source software developer network. Two types representation of the conceptual distance, message reply distance and common keyword distance, are defined. Appling these two types of conceptual distances, the mailing list of Linux kernel project is mined and virtual networks are constructed and analyzed. The evolution of Linux Kernel Mailing List social network is studied, where Mantel test is used to study the similarities and correlations between social networks. The study shows that in open-source software projects, (1) conceptual distances could be the key components in constructing the workspace of the developer network, and (2) Mantel test could be a powerful tool in studying the network.","2010","2025-04-25 15:29:06","2025-04-25 15:29:06","","89-104","","","","","","","Computer Science Technology and Applications","","","","","","","","","","","","","","","","","","","Taylor, JR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The accuracy of image orientation and camera calibration significantly affects the quality and accuracy of all subsequent photogrammetric processes, such as determining the spatial coordinates of individual points or 3D modeling. In the context of artificial vision, the full-field analysis procedure is used, which leads to the so-called Strcture from Motion (SfM), which includes the simultaneous determination of the camera's internal and external orientation parameters and the 3D model. The procedures were designed and developed by means of a photogrammetric system, but the greatest development and innovation of these procedures originated from the computer vision from the late 90s, together with the SfM method. The reconstructions on this method have been useful for visualization purposes and not for photogrammetry and mapping. Thanks to advances in computer technology and computer performance, a large number of images can be automatically oriented in a coordinate system arbitrarily defined by different algorithms, often available in open source software (VisualSFM, Bundler, PMVS2, CMVS, etc.) or in the form of Web services (Microsoft Photosynth, Autodesk 123D Catch, My3DScanner, etc.). However, it is important to obtain an assessment of the accuracy and reliability of these automated procedures. This paper presents the results obtained from the dome low close range photogrammetric surveys and processed with some open source software using the Structure from Motion approach: VisualSfM, OpenDroneMap (ODM) and Regard3D. Photogrammetric surveys have also been processed with the Photoscan commercial software by Agisoft. For the photogrammetric survey we used the digital camera Canon EOS M3 (24.2 Megapixel, pixel size 3.72 mm). We also surveyed the dome with the Faro Focus 3D TLS. Only one scan was carried out, from ground level, at a resolution setting of 1/4 with 3x quality, corresponding to a resolution of 7 mm / 10 m. Both TLS point cloud and Photoscan point cloud were used as a reference to validate the point clouds coming from VisualSFM, OpenDroneMap and Regards3D. The validation was done using the Cloud Compare open source software.","2019","2025-04-25 15:29:06","2025-04-25 15:29:06","","239-245","","","42-4","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences","","","","ISPRS","","","","","","","","","ISSN: 1682-1750 Issue: W14","","","","","","Brovelli, MA; Marin, AF","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The main reason for this is the potential that it provides for reducing development effort and increasing the end-product quality. At the same time, Open-Source Software (OSS) repositories are nowadays flourishing and can facilitate the reuse process, through the provision of a variety of software artifacts. However, up-to-date OSS reuse processes have mostly been opportunistic, leading to not fully capitalizing existing reuse potentials. In this study we propose a process (namely REACT) for improving planned OSS reuse practices, i.e., we define the activities that a software engineer can perform to reuse OSS artifacts. To illustrate the applicability of REACT, we provide an example, in which a mobile application is developed based upon the reuse of OSS artifacts. To validate the proposed process we compared the effort required to develop the application with and without adapting REACT process. Our preliminary results suggest that REACT may reduce up to 50% the effort required to build an application from scratch.","2018","2025-04-25 15:29:06","2025-04-25 15:29:06","","251-254","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The overall philosophy is to leverage best-in-class open source standards for medical image processing, parallel flow computation, geometric solid modelling, data assimilation, and mesh generation. It is actively used by researchers in Europe, North and South America, Asia, and Australia. It has been applied to numerous clinical problems; we illustrate applications of CRIMSON to real-world problems using examples ranging from pre-operative surgical planning to medical device design optimization. Author summary We provide the first full presentation in the literature of CRIMSON, the Cardiovascular Integrated Modelling and Simulation Package. CRIMSON consists of a graphical user interface desktop computer program for creating geometric models of blood vessels from medical imaging scans, specifying parameters such as the stiffness of the artery walls, the resistance of connected vessels which are not visible on the scans, and determining the appropriate parameters for all aspects of the model. CRIMSON additionally consists of the Flowsolver, a high-performance computing package which simulates the flow of blood through the models created in the graphical user interface. Whilst several packages which can simulate blood flow exist, most target general fluid simulations, and this lack of specialisation means that blood flow simulation is harder to perform, and can require ad hoc (and potentially scientifically-limiting) workflow decisions. CRIMSON's specialisation deals with these problems, as well as presenting a number of unique features which are unavailable elsewhere.","2021-05","2025-04-25 15:29:07","2025-04-25 15:29:07","","","","5","17","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm-community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.

However, the current strategies deployed by law enforcement to combat cybercrime have proven ineffective. Borne out of traditional notions of criminal behavior, these strategies and tactics are often ill-suited to prevent or punish cybercrime, which often defies the traditional notions of criminal behavior bounded by the corporeal world such as scale and proximity. This Comment argues that a more effective methodology in the fight against cybercrime is to develop a model of community policing, in which the power to deter and prevent cybercrime is divested into the hands of individual computer users. One such strategy for achieving effective community policing against cybercrime is through the increased use of open-source soft-ware, software in which users are given access to the underlying source code and may make modifications to that source code in order to ameliorate vulnerabilities that may enable cybercrime. This Comment looks at the development of traditional community policing strategies and argues that the increased use of open source software-spurned by greater involvement by government and corporations-may be a more effective technique in the fight against cybercrime.","2007","2025-04-25 15:29:07","2025-04-25 15:29:07","","601-629","","2","97","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The properties of OSS further complicate product assessment and maintenance for developers. This paper proposes a model for the iterative and multi-release OSS development process. Unlike traditional methods that oversimplify the problem by reducing the multi-decision space into a single-objective optimization problem, our approach suggests employing Multi-objective Evolutionary Algorithms (MOEAs) to solve the Optimal Release Time Planning Problem, enabling the simultaneous maximization of reliability and minimization of cost. We consider testing cost and system reliability, two critical dimensions, as the primary objectives, while also incorporating testing resource consumption as the third objective. The Non-dominated Sorting Genetic Algorithm II (NSGA-II) is chosen as the primary method for its effectiveness in MOEAs, with a special scenario outlined in the paper where NSGA-II may not guarantee optimal solutions. Demonstrating the practicality of our proposed method, we utilize open source data to assess release time and illustrate its superiority to NSGA-II. Numerical examples further showcase the model's effectiveness.","2023","2025-04-25 15:29:07","2025-04-25 15:29:07","","112248-112262","","","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Aligned with work that builds on the notion that an OSS development is tightly interrelated with its social environment (i.e., the OSS community), this study examines the relationship between interproject structure and OSS project success. OSS project success is reflected in two forms: popularity and knowledge creation. Extending the extant OSS literature, we theorize a contingent role of interproject connectedness. In particular, we posit three points: (1) an OSS project with more structural holes achieves higher popularity; (2) an OSS project with fewer structural holes yields higher knowledge creation; and (3) these two relationships are enhanced by an increase in project maturity. Using a dataset longitudinally collected from SourceForge.net, we found that OSS projects with widespread connectedness are more popular. This is especially so for those OSS projects in the mid-mature stage. We also found that OSS projects with a cohesive network achieve higher knowledge creation, irrespective of their maturity. Findings from our study can contribute to OSS literature by identifying OSS projects that are more likely to be successful.","2021-03","2025-04-25 15:29:07","2025-04-25 15:29:07","","","","1","30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-forprofit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 15:29:07","2025-04-25 15:29:07","","32-39","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Stability of software is one of the main features in software quality management that needs to be understood and accurately predicted. It deals with the impact resulting from software changes and argues that stable components lead to a cost-effective software evolution. Changes are most common phenomena present in OSS in comparison to proprietary software. This makes OSS system evolution a rich context to study and predict stability. Our objective in this work is to build stability prediction models that are not only accurate but also interpretable, that is, able to explain the link between the architectural aspects of a software component and its stability behavior in the context of OSS. Therefore, we propose a new approach based on classifiers combination capable of preserving prediction interpretability. Our approach is classifier-structure dependent. Therefore, we propose a particular solution for combining Bayesian classifiers in order to derive a more accurate composite classifier that preserves interpretability. This solution is implemented using a genetic algorithm and applied in the context of an OSS large-scale system, namely the standard Java API. The empirical results show that our approach outperforms state-of-the-art approaches from both machine learning and software engineering.","2014-04","2025-04-25 15:29:07","2025-04-25 15:29:07","","","","1","5","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In that community, companies always play auxiliary roles, and integrate the result of OSS into their business activities. However, in the Eclipse open source software community, the main role of OSS development activities is taken over by companies. The relationship between individuals and companies is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of a company. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify a structure of co-creation in an OSS ecosystem led by companies considering the Eclipse community as one particular case. It also constructs a co-creation process model to promote sustainable development for an OSS ecosystem following two axes 1) value sharing and value acquisition, and 2) quantitative development and qualitative development. Some mechanisms that drive this process are embedded everywhere in the Eclipse ecosystem.","2011","2025-04-25 15:29:08","2025-04-25 15:29:08","","","","","","","","","","","","","Portland State Univ, Maseeh Coll Engn & Comp Sci, Dept Engn & Technol Management; Portland State Univ, Off Informat Technol; IKON Off Solut","","","","","","","","","","","","","","","Kocaoglu, DF; Anderson, TR; Daim, TU","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Studying OSS is of particular interest: (1) to investigate socio-technical settings supporting user participation to the design process, which is considered to be the major strength of OSS design; (2) to gain insights into supporting the changing nature of the software industry, which is becoming more and more distributed and global, and which is thus increasingly making use of OSS design tools and methods. In this research, we characterized effective roles of participants, i.e. participation, on the basis of activities analysis in three online interaction spaces (discussion, documentation and implementation) during a continuous “pushed-by-users” design process of the Python project. Participation is targeted through a methodology articulating: (1) structural analyses (organization of the discussions, regularity and involvement of participants, quotes-based social network) in usage-oriented and development-oriented mailing lists of the projects' discussion space; (2) actions to the code and documentation made by participants in the implementation and documentation spaces. Besides the importance of the users' contribution to the process, OSS design is fostered by some key-participants, the cross-participants, who act as boundary spanners between the developers and the users, helping them to go beyond some barriers to participation. These findings can be reinforced developing software to automate the structural analysis of discussions and actions to the code and documentation. (C) 2008 Elsevier B.V.

The study revealed that while the OSSD learning environment motivated students to engage in real-world projects, tensions arose between the the innovative learning environment and the students' self-processes-their perceptions, expectations, beliefs, goals, and values. Most importantly, this study demonstrated key interplays between project authenticity and learner characteristics, which resulted in different identity representations and different perceptions among students, which in turn affected students' goal orientations, motivation to work on projects, commitment to team collaboration, attitudes toward expert coaching and feedback, and the use of collaborative technologies.","2010","2025-04-25 15:29:08","2025-04-25 15:29:08","","94-120","","2","4","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They are supported by peripheral developers, who contribute either via discussions or programming tasks, often for a limited time. It is unclear what role these peripheral developers play in the programming and communication efforts, as well as the temporary task-related sub-groups in the projects. We mine code-repository data and mailing-list discussions to model the relationships and contributions of developers in a social network and devise a method to analyze the temporal collaboration structures in communication and programming, learning about the strength and stability of social sub-groups in open-source software projects. Our method uses multi-modal social networks on a series of time windows. Previous work has reduced the network structure representing developer collaboration to networks with only one type of interaction, which impedes the simultaneous analysis of more than one type of interaction. We use both communication and version-control data of open-source software projects and model different types of interaction over time. To demonstrate the practicability of our measurement and analysis method, we investigate 10 substantial and popular open-source software projects and show that, if sub-groups evolve, modeling these sub-groups helps predict the future evolution of interaction levels of programmers and groups of developers. Our method allows maintainers and other stakeholders of open-source software projects to assess instabilities and organizational changes in developer interaction and can be applied to different use cases in organizational analysis, such as understanding the dynamics of a specific incident or discussion.","2022-04","2025-04-25 15:29:08","2025-04-25 15:29:08","","","","2","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Decentralized development and open collaboration in open source projects introduce unique challenges: code submissions from unknown entities, limited personpower for commit or dependency reviews, and bringing new contributors up-to-date in projects' best practices & processes. In 27 in-depth, semi-structured interviews with owners, maintainers, and contributors from a diverse set of open source projects, we investigate their security and trust practices. For this, we explore projects' behind-the-scene processes, provided guidance & policies, as well as incident handling & encountered challenges. We find that our participants' projects are highly diverse both in deployed security measures and trust processes, as well as their underlying motivations. Based on our findings, we discuss implications for the open source software ecosystem and how the research community can better support open source projects in trust and security considerations.

However, the number of new vulnerabilities keeps increasing in today's OSS systems. With today's increasingly important and complex OSS, lacking software security knowledge to handle security vulnerabilities in OSS development will result in more breaches that are serious in the future. Learning software security is a difficult and challenging task since the domain is quite context specific and the real project situation is necessary to apply the security concepts within the specific system. Many OSS proponents believe that the OSS community offers significant learning opportunities from its best practices. However, studies that specifically explore security knowledge sharing and learning in OSS communities are scarce. This research is intended to fill this gap by empirically investigating factors that affect knowledge sharing and learning about software security and the relationship among them. A conceptual model is proposed that helps to conceptualize the linkage between socio-technical practices and software security learning processes in OSS communities. A questionnaire and statistical analytical techniques were employed to test hypothesized relationships in the model to gain a better understanding of this research topic.","2018-12","2025-04-25 15:29:08","2025-04-25 15:29:08","","","","4","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, we report from a case study of X-Road, an originally Estonian eGovernment project for creating a data sharing infrastructure, which today is also used in other countries. We present the main characteristics of X-Road from the point of view of Government 3.0, how the X-Road project is organized, compare its organization to other OSS projects, identify who contributes to the project, and point out what challenges are perceived by their stakeholders.

In many Open Source Softoware Development (OSSD) communities, DM processes lie buried amongst vast amounts of publicly available data. Hidden within this data lie the rationale for decisions that led to the evolution and maintenance of software products. While there have been some efforts to extract DM processes from publicly available data, the rationale behind `boo' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million mails. This paper makes two main contributions. First. it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second. it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven. bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement). Our approach can be applied to extract rationale in other OSSD communities that have similar governance structures.","2021","2025-04-25 15:29:08","2025-04-25 15:29:08","","1008-1019","","","","","","","International Conference on Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT","","","","","","","","","ISSN: 0270-5257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Instead, we are in a new age where software is developed by a networked community of individuals and organizations, which base their relations to each other on mutual interest. Paradoxically, recent research suggests that software development can actually be jointly-developed by rival firms. For instance, it is known that the mobile-device makers Apple and Samsung kept collaborating in open source projects while running expensive patent wars in the court. Taking a case study approach, we explore how rival firms collaborate in the open source arena by employing a multi-method approach that combines qualitative analysis of archival data (QA) withmining software repositories (MSR) and Social Network Analysis (SNA). While exploring collaborative processes within the OpenStack ecosystem, our research contributes to Software Engineering research by exploring the role of groups, sub-communities and business models within a high-networked open source ecosystem. Surprising results point out that competition for the same revenue model (i.e., operating conflicting business models) does not necessary affect collaboration within the ecosystem. Moreover, while detecting the different sub-communities of the OpenStack community, we found out that the expected social tendency of developers to work with developers from same firm (i.e., homophony) did not hold within the OpenStack ecosystem. Furthermore, while addressing a novel, complex and unexplored open source case, this research also contributes to the management literature in coopetition strategy and high-tech entrepreneurship with a rich description on how heterogeneous actors within a high-networked ecosystem (involving individuals, startups, established firms and public organizations) joint-develop a complex infrastructure for big-data in the open source arena.","2015-07-24","2025-04-25 15:29:08","2025-04-25 15:29:08","","","","","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations.

Conflicting agendas may create miss-alignment with the firm's internal requirements strategy. In communities with meritocratic governance or with aspects thereof, a firm has the opportunity to affect the RE process in line with their own agenda by gaining influence through active and symbiotic engagements. Objective: The focus of this study has been to identify what aspects that firms should consider when they assess their need of influencing the RE process in an OSS community, as well as what engagement practices that should be considered in order to gain this influence. Method: Using a design science approach, 21 interviews with 18 industry professionals from 12 different software-intensive firms were conducted to explore, design and validate an artifact for the problem context. Results: A Community Strategy Framework (CSF) is presented to help firms create community strategies that describe if and why they need influence on the RE process in a specific (meritocratic) OSS community, and how the firm could gain it. The framework consists of aspects and engagement practices. The aspects help determine how important an OSS project and its community is from business and technical perspectives. A community perspective is used when considering the feasibility and potential in gaining influence. The engagement practices are intended as a tool-box for how a firm can engage with a community in order to build influence needed. Conclusion: It is concluded from interview-based validation that the proposed CSF may provide support for firms in creating and tailoring community strategies and help them to focus resources on communities that matter and gain the influence needed on their respective RE processes.","2019-08","2025-04-25 15:29:08","2025-04-25 15:29:08","","102-114","","","112","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently, there exists no working operationalization available that can be used to determine the health of open source ecosystems. Health is typically looked at from a project scope, not from an ecosystem scope. Objectives: With such an operationalization, stakeholders can make better decisions on whether to invest in an ecosystem: developers can select the healthiest ecosystem to join, keystone organizers can establish which governance techniques are effective, and end-users can select ecosystems that are robust, will live long, and prosper. Method: Design research is used to create the health operationalization. The evaluation step is done using four ecosystem health projects from literature. Results: The Open Source Ecosystem Health Operationalization is provided, which establishes the health of a complete software ecosystem, using the data from collections of open source projects that belong to the ecosystem. Conclusion: The groundwork is done, by providing a summary of research challenges, for more research in ecosystem health.

What strategies are adopted by the sponsor to influence the organizational structure of free software communities? Two constructs are central to the study: organizational structure and sponsorship. For this research, we adopted case study methodology and three free software communities were studied. In the analysis of the results it was evidenced that sponsors influence decision making, definition of community key roles, and a formalization of norms.

Such coupling has been developed before, but, to the best of our knowledge, no detailed discussion of the programming issues to be faced in order to attain efficient implementation on parallel architectures, has ever been presented to date. In this paper, we describe in detail the underlying multi-scale models, their coupling procedure, along side with a description of the relevant input variables, to facilitate third-parties usage. The code is designed to exploit parallel computing platforms, taking advantage also of the recent AVX-512 instruction set. We focus on LBsoft structure, functionality, parallel implementation, performance and availability, so as to facilitate the access to this computational tool to the research community in the field.

OSS project leaders implement quality controls to improve the quality of developed products. They may not be aware that their implementation of quality controls produces a side effect-quality controls signal unobservable project quality to volunteers and promote volunteers' continued participation intentions (VCPI). We focus on two quality controls-accreditation and code acceptance, which, respectively, map to the input and output quality of an OSS project-and compare their respective effects on VCPI in community-founded and spinout projects. We propose that accreditation and code acceptance influence VCPI by signaling unobservable input and output quality to volunteers. As we focus on continued participation, we theorize as to how volunteers' tenure in OSS projects moderates the relationships between the signaling effects of input and output quality controls and VCPI. Furthermore, we theorize as to how the OSS project type moderates the effects of quality controls on VCPI. We surveyed 304 volunteers from 40 OSS projects and constructed a two-level model of project and developer factors to explain VCPI. Our findings indicate that both accreditation and code acceptance enhance VCPI. The signaling effects on VCPI associated with accreditation decline with volunteer tenure, but those associated with code acceptance do not. Accreditation and code acceptance influence VCPI, with community-founded projects exhibitingweaker direct positive effects and spinout projects exhibiting stronger direct positive effects. We discuss the theoretical and practical implications of these findings.","2017-09","2025-04-25 15:29:09","2025-04-25 15:29:09","","603-625","","3","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These communities' survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSScoach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process. However, there is also some indication that FLOSScoach did not lower the technical barriers.","2015","2025-04-25 15:29:09","2025-04-25 15:29:09","","160-169","","","","","","","","","","","ThoughtWorks; AvenueCode; Google; take.net; RARO Labs; Avanti; IBM; CNPq; CAPES; FAPEMIG; UFmG; PUC Minas; CEFET MG","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although OSS is usually free of charge, its diffusion remains limited, Should government intervene to promote the diffusion of OSS, and offer potential adopters some learning or financial support? This paper examines whether public subsidies for OSS are socially desirable. and how the extent of compatibility between OSS and proprietary software (PS) might influence the optimal subsidy offered. We consider a mixed duopoly model in which a PS company competes with an OSS community. Users are heterogeneous in their ability to use OSS, and their utility depends on the number of users who adopt the same or compatible software (existence of network externalities). Four situations are distinguished: full compatibility between OSS and PS, full incompatibility, and one-way compatibility (either only OSS or PS is compatible). We show that if the government places more weight on consumer surplus. public subsidies are welfare-enhancing. But the optimal subsidy level is larger with full compatibility and PS compatibility than full incompatibility and OSS compatibility. These results suggest that government policy towards OSS should be conditional on the degree of compatibility between PS and OSS.","2014","2025-04-25 15:29:09","2025-04-25 15:29:09","","1174-1184","","2","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It has received considerable attention in the scientific literature, but mostly in the professional press. In fact, there is much debate over its actual commercial and organizational value. Since the public discourse accompanying an IT may influence adoption decisions, it is important to consider IT specialists' perceptions of the discourse on OSS. In this study, we investigated the relationship between IT specialists' profiles, IT specialists' reception of the public discourse on OSS, and their organizations' receptivity to OSS. Drawing on the socio-cognitive perspective of IT innovation adoption and the organizing vision theory, a survey of 271 IT specialists was conducted to examine these issues. Our results indicate that a majority of IT specialists in our sample are rather neutral about the OSS concept conveyed in the public discourse. However, our sample also comprises respondents with more extreme perceptions who can be classified as either supporters or detractors. Our results indicate that detractors have more years of experience but have been less exposed to OSS than supporters, and that IT specialists' perceptions of the OSS concept are positively associated with their organizations' openness to OSS adoption and, to a lesser extent, with the existence of an organizational policy that favors OSS adoption. Altogether, our findings provide strong support for the organizing vision theory and the idea that the popularity of an IT innovation concept favors the adoption of the material IT innovation in organizations. By providing a preliminary test of a nomological network of IT specialists' perceptions of the OSS concept, our study offers insights as to why organizations may or may not take OSS into account in their software procurement decisions.

NAICS is the industry classification scheme used by the governments of Canada, Mexico and the United States to carry out their respective economic censuses. NAICS is considered a rational system that uses the underlying economic principle of similar production processes as the basis for its classes. For the Information Sector of the economy, as formulated in NAICS, a key production process is the acquisition and defense of copyright. With open source, copyleft licensing eliminates copyright acquisition and protection as major production processes, suggesting that the open source software industry warrants a separate NAICS category. More importantly, our analysis suggests that NAICS cannot be understood as a taxonomy of objective economic activity but is instead a politically and historically contingent system of data classification.","2005","2025-04-25 15:29:09","2025-04-25 15:29:09","","117-127","","3","32","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although field surveys using these methods are relatively straightforward, ERT and IP data require the application of inverse methods prior to any interpretation. Several established non-commercial inversion codes exist, but they typically require advanced knowledge to use effectively. ResIPy was developed to provide a more intuitive, user-friendly, approach to inversion of geoelectrical data, using an open source graphical user interface (GUI) and a Python application programming interface (API). ResIPy utilizes the mature R2/cR2 inversion codes for ERT and IP, respectively. The ResIPy GUI facilitates data importing, data filtering, error modeling, mesh generation, data inversion and plotting of inverse models. Furthermore, the easy to use design of ResIPy and the help provided inside makes it an effective educational tool. This paper highlights the rationale and structure behind the interface, before demonstrating its capabilities in a range of environmental problems.

Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased.

For optimal impact, the limited time and effort for complexity control, called anti-regressive work, should be applied to the elements of the system which are frequently changed and are complex. Based on this, we propose a maintenance guidance model (MGM) which is tested against real-world data. MGM takes into account several dimensions of complexity: size, structural complexity and coupling. Results show that maintainers of the eight open source systems studied tend, in general, to prioritize their anti-regressive work in line with the predictions given by our MGM, even though, divergences also exist. MGM offers a history-based alternative to existing approaches to the identification of elements for anti-regressive work, most of which use static code characteristics only.","2007","2025-04-25 15:29:10","2025-04-25 15:29:10","","114+","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE; IEEE Comp Soc; IEEE France Sect; TCSE; IEEE Comp Soc, Tech Council Software Engn; Reeng Forum; Univ Waterloo; Univ Studi Sannio","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Involving student teams in real-world projects developed by professional software engineers for actual users is invaluable. Free and Open Source Software (FOSS) has emerged as an important approach to creating, managing, and distributing software products. Involvement in a FOSS project provides students with experience developing within a professional environment, with a professional community, and has the additional benefit that all communication and artifacts are publicly accessible. Humanitarian Free and Open Source Software (HFOSS) projects benefit the human condition in some manner. They can range from disaster management to microfinance to election-monitoring applications. This article discusses the benefits and challenges of students participating in HFOSS projects within the context of undergraduate computing degree programs. This article reports on a 6-year study of students' self-reported attitudes and learning from participation in an HFOSS project. Results indicate that working on an HFOSS project increases interest in computing.

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as “joiners”) can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.","2011-01","2025-04-25 15:29:10","2025-04-25 15:29:10","","208-238","","1","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The software is developed in Objective-C on a Macintosh platform under the MacOS X operating system using the GNUstep development environment. It also benefits from the extremely fast and optimized 3D graphic capabilities of the OpenGL graphic standard widely used for computer games optimized for taking advantage of any hardware graphic accelerator boards available. In the design of the software special attention was given to adapt the user interface to the specific and complex tasks of navigating through large sets of image data. An interactive jog-wheel device widely used in the video and movie industry was implemented to allow users to navigate in the different dimensions of an image set much faster than with a traditional mouse or on-screen cursors and sliders. The program can easily be adapted for very specific tasks that require a limited number of functions, by adding and removing tools from the program's toolbar and avoiding an overwhelming number of unnecessary tools and functions. The processing and image rendering tools of the software are based on the open-source libraries ITK and VTK.

The culture and norms of FLOSS appear to be formulated by what is privileged/marginalized by men in the context of FLOSS, and such men's valuing is likely to threaten women FLOSS participants' face. Our findings are 1) in the FLOSS context, there are gender-based differences in determining what threatens face on the basis of gendered expectations of what is polite, and 2) women-dominated FLOSS participants are “practically” polite in software development practices. These findings were explored through an in-depth analysis of interaction episodes on the email list, archival public interview data of women FLOSS developers, FLOSS development environment, and instructive materials shared in public. Our paper shows how politeness theory can be extended to the “practice” of coding and non-coding work, and provides FLOSS communities with guidelines for involving and sustaining women participants in FLOSS development.","2013","2025-04-25 15:29:10","2025-04-25 15:29:10","","3168-3177","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE Comp Soc; Univ Hawaii, Shidler Coll Business","","","","","","","","","ISSN: 1060-3425","","","","","","Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study aims to assist a community of OSS developers in quantifying the product's reliability. This research proposes reliability growth models for OSS by incorporating dynamicity in the debugging process. For this, stochastic differential equation-based analytical models are developed to represent the instantaneous rate of error generation. The fault introduction rate is modeled using exponential and Erlang distribution functions. The empirical applications of the proposed methodology are verified using the real-life failure data of the Open Source Software projects, GNU Network Object Model Environment, and Eclipse. A soft computing technique, Genetic Algorithm, is applied to estimate model parameters. Cross-validation is also performed to examine the forecasting efficacy of the model. The predictive power of the developed models is compared with various benchmark studies. The data analysis is conducted using the R statistical computing software. The results demonstrate the proposed models' efficacy in parameter estimation and predictive performance. In addition, the optimal release time policy based on the proposed mathematical models is presented by formulating the optimization model that intends to minimize the total cost of software development under reliability constraints.

Closed-loop experiments provide unique insights into brain dynamics and function. To facilitate a wide range of closed-loop experiments, we created an open-source software platform that enables high-performance real-time processing of streaming experimental data. Approach. We wrote Falcon, a C++ multi-threaded software in which the user can load and execute an arbitrary processing graph. Each node of a Falcon graph is mapped to a single thread and nodes communicate with each other through thread-safe buffers. The framework allows for easy implementation of new processing nodes and data types. Falcon was tested both on a 32-core and a 4-core workstation. Streaming data was read from either a commercial acquisition system (Neuralynx) or the open-source Open Ephys hardware, while closed-loop TTL pulses were generated with a USB module for digital output. We characterized the round-trip latency of our Falcon-based closed-loop system, as well as the specific latency contribution of the software architecture, by testing processing graphs with up to 32 parallel pipelines and eight serial stages. We finally deployed Falcon in a task of real-time detection of population bursts recorded live from the hippocampus of a freely moving rat. Main results. On Neuralynx hardware, round-trip latency was well below 1 ms and stable for at least 1 h, while on Open Ephys hardware latencies were below 15 ms. The latency contribution of the software was below 0.5 ms. Round-trip and software latencies were similar on both 32- and 4-core workstations. Falcon was used successfully to detect population bursts online with similar to 40 ms average latency. Significance. Falcon is a novel open-source software for closed-loop neuroscience. It has sub-millisecond intrinsic latency and gives the experimenter direct control of CPU resources. We envisage Falcon to be a useful tool to the neuroscientific community for implementing a wide variety of closed-loop experiments, including those requiring use of complex data structures and real-time execution of computationally intensive algorithms, such as population neural decoding/encoding from large cell assemblies.","2017-08","2025-04-25 15:29:11","2025-04-25 15:29:11","","","","4","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To provide a more accurate and realistic reflection of the fire development, the current paper develops a generic middleware which interfaces between the computational fluid dynamics (CFD) software Fire Dynamics Simulator (FDS) and the finite element (FE) analysis software OpenSees. This framework enables a fully integrated simulation of a realistic fire scenario including the heat transfer through the structure and the resulting thermo-mechanical response. The proposed framework is open-source and freely available and therefore can be used and further developed by researchers and practicing engineers and customised to their requirements. This paper shows validation against two sets of experimental results and one real fire incident. A number of different types of thermal boundary conditions such as gas temperatures and heat fluxes, are obtained from the CFD analysis and are then used in the subsequent heat transfer and thermo-mechanical analysis. The primary advantage of this computational tool is that it provides consultants and designers with the means to undertake large-scale projects requiring performance-based fire engineering solutions.","2023-10","2025-04-25 15:29:11","2025-04-25 15:29:11","","","","","140","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The degree distributions of links in both the in-directed and out-directed dependency networks follow Zipf's law for the intermediate nodes, but the heavily linked nodes and the poorly linked nodes deviate from this trend and exhibit finite-size effects. The finite-size parameters make a quantitative distinction between the in-directed and out-directed networks. For the out-degree distribution, the initial condition for a dynamic evolution corresponds to the limiting count of the most heavily linked nodes that the out-directed network can finally have. The number of nodes contributing out-directed links grows with every generation of software release, but this growth ultimately saturates toward a terminal value, due to the finiteness of semantic possibilities in the network.","2014","2025-04-25 15:29:11","2025-04-25 15:29:11","","71-92","","1","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The OSS community has some special characteristics (such as worldwide geographical distribution of both users and developers and missing resources) which are an obstacle to the direct adoption of many usability techniques as specified in the human-computer interaction (HCI) field. Objective: The aim of this research is to adapt and evaluate the feasibility of applying four usability techniques: user profiles, personas, direct observation and post-test information to four OSS projects from the viewpoint of the development team. Method: The applied research method was a multiple case study of the following OSS projects: Quite Universal Circuit Simulator, PSeInt, FreeMind and OpenOffice Writer. Results: We formalized the application procedure of each of the adapted usability techniques. We found that either there were no procedures for adopting usability techniques in OSS or they were not fully systematized. Additionally, we identified the adverse conditions that are an obstacle to their adoption in OSS and propose the special adaptations required to overcome the obstacles. To avoid some of the adverse conditions, we created web artefacts (online survey, wiki and forum) that are very popular in the OSS field. Conclusion: It is necessary to adapt usability techniques for application in OSS projects considering their idiosyncrasy. Additionally, we found that there are obstacles (for example, number of participant users, biased information provided by developers) to the application of the techniques. Despite these obstacles, it is feasible to apply the adapted techniques in OSS projects.","2019-03","2025-04-25 15:29:11","2025-04-25 15:29:11","","48-64","","","107","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Larger teams tend to producemore favorable project performance when the project being developed has a high level of structural interdependency while projects with a low level of structural interdependency require smaller teams in order to achieve better project performance. Meanwhile, centralized teams tend to have a positive impact on project performance when the OSS project has a high level of structural interdependency. However, when a project has a low level of structural interdependency, centralized teams can impair project performance.

However, ERP systems are complex tools, particularly for small and medium size enterprises (SMEs). For this reason, new ERP configurations have arisen, such as Open Source Software-ERP (OSS-ERP). In the website Sourceforge.net, we can identify 2058 projects about OSS-ERP, although all of them have not had an impact on the ERP market. This data is indicative of the increasing relevance of this enterprise solution for organizations. At this moment, the OSS-ERP vendors with a greater diffusion are Compiere, Openbravo, Abanq (previously FacturaLux), ERP5, Tiny ERP, Fisterra, OFBiz, SQL-Ledger and WebERP. OSS-ERP has three relevant advantages for organizations: (1) increased adaptability, (2) decreased reliance on a single supplier, (3) reduced costs. OSS-ERP generally include the necessary functions to integrally manage all the activities of a company. Due to their high flexibility, these tools can be adapted to the client's specific needs. Furthermore, as OSS-ERP are based on open software technologies, organizations do not have to pay licenses or exclusive contracts. With the collaboration of partners, OSS-ERP vendors receive benefits for the support services. Research in OSS has identified individual personal motives for using OSS software, analyzing specific OSS solutions, or the OSS movement itself. The literature in Enterprise solutions has also analyzed the main organizational factors for successfully implementing an ERP system. However, OSS-ERP is a research topic barely analyzed by the literature. This paper's aim is to specifically focus on the organizational and motivational factors for implementing OSS-ERP. The authors developed a research work for testing the impact of organizational and motivational factors on the implementation of OSS-ERP by means of a survey of organizations with OSS-ERP and OSS-ERP users.","2010","2025-04-25 15:29:11","2025-04-25 15:29:11","","257-273","","","","","","","Computer Science Technology and Applications","","","","","","","","","","","","","","","","","","","Taylor, JR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, DNNs alone are susceptible to obvious mistakes that violate simple, common sense concepts and are limited in their ability to use explicit knowledge to guide their search and decision making. While overall DNN performance metrics may be good, these obvious errors, coupled with a lack of explainability, have prevented widespread adoption for crucial tasks such as medical image analysis. The purpose of this paper is to introduce SimpleMind, an open-source software environment for Cognitive AI focused on medical image understanding. It allows creation of a knowledge base that describes expected characteristics and relationships between image objects in an intuitive human-readable form. The knowledge base can then be applied to an input image to recognize and understand its content. SimpleMind brings thinking to DNNs by: (1) providing methods for reasoning with the knowledge base about image content, such as spatial inferencing and conditional reasoning to check DNN outputs; (2) applying process knowledge, in the form of general-purpose software agents, that are dynamically chained together to accomplish image preprocessing, DNN prediction, and result post-processing, and (3) performing automatic co-optimization of all knowledge base parameters to adapt agents to specific problems. SimpleMind enables reasoning on multiple detected objects to ensure consistency, providing cross-checking between DNN outputs. This machine reasoning improves the reliability and trustworthiness of DNNs through an interpretable model and explainable decisions. Proof-of-principle example applications are provided that demonstrate how SimpleMind supports and improves deep neural networks by embedding them within a Cognitive AI environment.","2023-04-13","2025-04-25 15:29:11","2025-04-25 15:29:11","","","","4","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This interest stems not only from cost savings, but also from benefits concerning reproducibility and collaboration. Technical challenges hamper practical reproducibility, especially when multiple software packages are required to conduct an analysis. In this study, we use containerization to package a GEOBIA workflow in a well-defined FOSS environment. We explore the approach using two software stacks to perform an exemplary analysis detecting destruction of buildings in bi-temporal images of a conflict area. The analysis combines feature extraction techniques with segmentation and object-based analysis to detect changes using automatically-defined local reference values and to distinguish disappeared buildings from non-target structures. The resulting workflow is published as FOSS comprising both the model and data in a ready to use Docker image and a user interface for interaction with the containerized workflow. The presented solution advances GEOBIA in the following aspects: higher transparency of methodology; easier reuse and adaption of workflows; better transferability between operating systems; complete description of the software environment; and easy application of workflows by image analysis experts and non-experts. As a result, it promotes not only the reproducibility of GEOBIA, but also its practical adoption.","2017-03","2025-04-25 15:29:11","2025-04-25 15:29:11","","","","3","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Commonly, they emerge from one product when there is a need to create tailored variants, or from existing variants created in an ad-hoc way once their separated maintenance and evolution become challenging. Despite the vast literature about re-engineering systems into SPLs and related technical approaches, there is a lack of detailed analysis of the process itself and the effort involved. In this paper, we provide and analyze empirical data of the extraction processes of two open-source case studies, namely ArgoUML and Phaser. Both cases emerged from the transition of a monolithic system into an SPL. The analysis relies on information mined from the version control history of their respective source-code repositories and the discussion with developers that took part in the process. Unlike previous works that focused mostly on the structural results of the final SPL, the contribution of this study is an in-depth characterization of the processes. With this work, we aimed at providing a deeper understanding of the strategies for SPL extraction and their implications. Our results indicate that the source code changes can range from almost a fourth to over half of the total lines of code. Developers may or may not use branching strategies for feature extraction. Additionally, the problems faced during the extraction process may be due to lack of tool support, complexity on managing feature dependencies and issues with feature constraints. We made publicly available the datasets and the analysis scripts of both case studies to be used as a baseline for extractive SPL adoption research and practice.","2022-07","2025-04-25 15:29:12","2025-04-25 15:29:12","","","","4","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Meta-analysis and meta-regression are statistical methods for synthesizing and modelling the results of different studies, and are critical research synthesis tools in ecology and evolutionary biology (E&E). However, many E&E researchers carry out meta-analyses using software that is limited in its statistical functionality and is not easily updatable. It is likely that these software limitations have slowed the uptake of new methods in E&E and limited the scope and quality of inferences from research syntheses. 2. We developed OpenMEE: Open Meta-analyst for Ecology and Evolution to address the need for advanced, easy-to-use software for meta-analysis and meta-regression. OpenMEE has a cross-platform, easy-to-use graphical user interface (GUI) that gives E&E researchers access to the diverse and advanced statistical functionalities offered in R, without requiring knowledge of R programming. 3. OpenMEE offers a suite of advanced meta-analysis and meta-regression methods for synthesizing continuous and categorical data, including meta-regression with multiple covariates and their interactions, phylogenetic analyses, and simple missing data imputation. OpenMEE also supports data importing and exporting, exploratory data analysis, graphing of data, and summary table generation. 4. As intuitive, open-source, free software for advanced methods in meta-analysis, OpenMEE meets the current and pressing needs of the E&E community for teaching meta-analysis and conducting high-quality syntheses. Because OpenMEE's statistical components are written in R, new methods and packages can be rapidly incorporated into the software. To fully realize the potential of OpenMEE, we encourage community development with an aim to advance the capabilities of meta-analyses in E&E.","2017-08","2025-04-25 15:29:12","2025-04-25 15:29:12","","941-947","","8","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We analyze the posting and replying activities of the participants by counting the number of email messages they posted to the lists and the number of replies they made to questions others posted. We found out that participants interact and share their knowledge a lot, their positing activity is fairly highly correlated with their replying activity, the characteristics of posting and replying activities are different for different kinds of lists, and the knowledge sharing activity of self-organizing Free/Open Source communities could best be explained in terms of what we called “Fractal Cubic Distribution” rather than the power-law distribution mostly reported in the literature.

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 15:29:12","2025-04-25 15:29:12","","484-510","","","46","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study investigates factors that affect the selection of software for public sector information systems with, an emphasis on how Free and Open Source Software ( FOSS) is used and could be used in such projects. The objectives of the study are as follows. The study aims to identify factors that affect the adoption of Software in Sri Lankan government sector projects. In addition to this it identifies features that are considered as important in such large Information Systems, and how they relate to Open Source Software adoption in the context of the public sector in Sri Lanka. The findings are analyzed and suitable recommendations are presented for better selection of software in the public sector. The work is important as it identifies and highlights factors that affect the choice of software in the public sector. This is important for several categories of people. It is of importance to the strategic management and policy makers to know what drives the information system procurement decisions in order to make more relevant policies and guidelines that are congruent with the needs in government sector departments. It is useful when advocating new technologies and information systems. This is especially true when advocating the use of Free and Open Source software for the use in the public sector in a wholesome and sustainable manner. The research is also important to software vendors and solution providers to the public sector in identifying what factors need to be taken in to account when bidding for public sector IS projects. The research is of a qualitative nature. It consists of multiple case studies of selected government sector departments and projects in Sri Lanka. The study investigates information systems developed by internal staff, developed by external consultants, procured systems, system implementation via private public partnerships (PPP) and projects guided by the Information and Communication Technology Agency (ICTA) of Sri Lanka. Data was gathered through interviews of staff at different levels of selected government sector Information Systems projects. The data was comparatively analyzed on a case by case basis to identify common patterns and trends among the investigated organizations and projects. The identified factors affecting the choice of software include the cost, technical specifications, bidder's expertise in selected technology and user's expertise in selected technology amongst other factors described in the full paper. The study identifies patterns between the choice of software - FOSS or non FOSS, and these identified factors. Based on these, recommendations are given to adopt and benefit from the use of FOSS in public sector enterprise level software projects.","2011","2025-04-25 15:29:12","2025-04-25 15:29:12","","239-252","","","","","","","","","","","","","","","","","","","","","","","","","","Grant, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Previous work done by Hinds [5] suggested social network structure was instrumental towards the success of an OSS project, as measured by activity and output. The follow-up paper by Thuds [4] discovered that his hypotheses, based on social network theory and previous research on the importance of subgroup connectedness, were vastly different than the results of his study of over 100 successful OSS projects. He concluded that the social network structure had no significant effect on project success We outline how his approach disregarded potentially important factors and through a new study evaluate the role of the OSS developer network as it pertains to long-term project popularity. We also present an initial investigation into the adequacy of using the SourceForge activity percentile as a long-term success metric In contrast with Hinds, we show that previously existing developer-developer ties are an indicator of past and future project popularity.","2010","2025-04-25 15:29:12","2025-04-25 15:29:12","","2887-2896","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","Univ Hawaii, Shidler Coll Business","","","","","","","","","ISSN: 1060-3425","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The developers' sentiment in this process can have an impact on their working willingness and efficiency. Monitoring sentiment factors can help to improve OSS development and management. However, no method has been proposed to dynamically monitor the sentiment phenomena during the OSS development process. In this paper, an approach to detect Negative Sentiment-related Events (NSE) is proposed. It consists of two steps. The first step is to identify the burst interval of negative comments from open source projects, which corresponds to a NSE. The second step is to annotate this NSE with its event type. To support this approach, the types of NSEs in OSS projects are defined through an empirical study and classifiers are trained to annotate event types automatically. Moreover, conversation disentanglement techniques are employed to make the comments extracted more complete. Finally, the factors that have an influence on NSEs in the OSS project are studied.","2021","2025-04-25 15:29:12","2025-04-25 15:29:12","","92-100","","","","","","","Asia-Pacific Software Engineering Conference","","","","Minist Sci & Technol; Taipei Med Univ; Acad Sinica; Foxconn Technol Grp; PremiumSoft","","","","","","","","","ISSN: 1530-1362","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The technique can be also used lighting analysis of both external (to the building) as well as for internal spaces. An architectural model built in SketchUp (free) CAD software is exported in two different forms for the Radiance Lighting Simulation Suite to provide the lighting analysis. The different exports formats allow the 3D CAD model to be accessed directly via Radiance for full lighting analysis or via the Blender Animation program for a graphical user interface limited option analysis.

Despite concerns that reviews may be ignored, or that discussions will deadlock because too many uninformed stakeholders are involved, we find that this approach works well in practice. In this paper, we describe an empirical study to investigate the mechanisms and behaviours that developers use to find code changes they are competent to review. We also explore how stakeholders interact with one another during the review process. We manually examine hundreds of reviews across five high profile OSS projects. Our findings provide insights into the simple, community-wide techniques that developers use to effectively manage large quantities of reviews.

In order to investigate the importance of AK of OSS components in integration, we conducted an exploratory empirical study. Based on in-depth interviews with 12 IT professionals, this paper presents insights into the following questions: 1) what AK of OSS is needed? 2) Why is AK of OSS needed? 3) Is AK of OSS generally available? And 4) what is the relative importance of AK? Based on these new insights, we provide a research agenda to further the research field of software architecture in OSS.","2011","2025-04-25 15:29:12","2025-04-25 15:29:12","","142+","","","365","","","","IFIP Advances in Information and Communication Technology","","","","CAPES, Minist Educ, Coordinat Improvement Higher Educ Personnel; CNPQ, Minist Sci & Tecnol, Natl Council Sci & Technol Dev; FAPESB, State Bahia Res Agcy; Petrobras","","","","","","","","","ISSN: 1868-4238","","","","","","Hissam, SA; Russo, B; Neto, MGD; Kon, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article, the author examines the case of the “circuit riders,” a progressive technology movement in the United States that promotes information technology use among nonprofit and grassroots organizations, to show how a particular technology is politicized through field-level interactions. Applying and contributing to actor-network theory, the author finds that translation takes place as an organizational process by which actors associate the ideals of the technology in question with their political ideals and then attempt to enroll other actors to accept the resultant associations.

This paper presents the state of the art of how to combine MDD methods with OS software development. The approach is called Open Models software development which is expected to combine the benefits of both worlds. The fundamental idea of Open Models development is to apply community-driven collaborative MDD. In this paper, Open Models development is exemplified by constructing Resource Availability Service (RAS). RAS is a web service for providing availability information about resources such as services, content, users and terminals. This paper shows that Open Models development is feasible from technical point of view although there are still great challenges in tooling. In addition, more empirical research is needed in studying attractiveness of Open Models.","2009","2025-04-25 15:29:12","2025-04-25 15:29:12","","185-190","","","","","","","","","","","Networked European Software & Serv Initiative","","","","","","","","","","","","","","","Boness, K; Fernandes, JM; Hall, JG","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article aims at developing a research model for investigating the antecedents of OSS adoption decisions in HCOs. Methods: Based on a conceptual framework derived from a synthesis of the literature on IT adoption in organizations, we conducted 18 semi-structured interviews with IT experts from all levels of the Province of Quebec's health and social services sector in Canada. We also interviewed 10 IT suppliers in the province. A qualitative data analysis of the interviews was performed to identify major antecedents of OSS adoption decisions in HCOs. Results: Eight factors associated with three distinct theoretical perspectives influence OSS adoption. More specifically, they are associated with the classical diffusion of innovations theory, the theory of resources, as well as institutional theory and its spin-off, the organizing vision theory. The factors fall under three categories: the characteristics of OSS as an innovation, the characteristics of the HCO with respect to its ability to absorb OSS, and the characteristics of the external environment with respect to institutional pressures and public discourse surrounding OSS. We shed light on two novel factors that closely interact with each other: (1) interest of the health care community in the public discourse surrounding OSS, and (2) clarity, consistency and richness of this discourse, whether found in magazines or other media. Conclusions: OSS still raises many questions and presents several challenges for HCOs. It is crucial that the different factors that explain an HCO's decision on OSS adoption be considered simultaneously. Doing so allows a better understanding of HCOs' rationale when deciding to adopt, or not to adopt, OSS. (C) 2013 Elsevier Ireland Ltd.

Due to the rising dominance of OSS in the software industry; not only practitioners, but researchers as well as academicians are also keen to understand the OSS development and evolution process. Several studies have been conducted in the past in this regard. Most of the existing work relates to growth analysis of OSS projects using source code level metrics. Lately, metrics related to change activity have also been included to understand OSS evolution. Change activity as recorded in Source Code Management (SCM) systems is used in a few cases. Most of the work deals with finding change size, and change effort distributions. A few studies do change profile analysis as OSS systems evolve. But that is restricted to a few of the change categories, e.g., adaptive v/s non-adaptive changes, corrective v/s non-corrective changes. This research study explores change profiles of 106 OSS systems by extracting change type information from their SCM repositories and then categorizing these changes automatically into five different categories - corrective, adaptive, perfective, preventive, and enhancement related. The idea is to understand the way OSS projects undergo change through long periods of time. The results indicate that change behavior of the OSS projects is different for different types of changes.","2016","2025-04-25 15:29:13","2025-04-25 15:29:13","","741-745","","","10027","","","","Lecture Notes in Computer Science","","","","Norwegian Res Council","","","","","","","","","ISSN: 0302-9743","","","","","","Abrahamsson, P; Jedlitschka, A; Duc, AN; Felderer, M; Amasaki, S; Mikkonen, T","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To achieve this goal, publiclyavailable data about doctors in the state of Virginia and hospitals across the United States was gathered. Visualizations were created to answer potential patient questions about doctors, such as which nearby practitioner has the most experience. Data from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, in conjunction with Census Bureau data, was explored. The census information facilitated classification of each hospital as urban or rural based on location. Multiple linear regression and random forest analysis were used to determine which elements of patient experience most influence whether a patient would recommend a hospital. Outputs from the multiple linear regression models indicated that of the statistically significant predictors, doctor communication and staff responsiveness most impacted recommendation scores in rural hospitals, and nurse communication and pain management were the most impactful for urban hospitals. Random forest analysis indicated that staff responsiveness and nurse communication were the most important variables in determining high or low recommendation scores for rural hospitals, and care transition and nurse communication were the most important variables for urban hospitals. These results will be used to create filtering options for the SEMOSS patient portal.","2017","2025-04-25 15:29:13","2025-04-25 15:29:13","","144-149","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our narratives indicate that for both cases there was strong goodwill towards open source yet the trajectories of implementation differed widely. Drawing upon ideas of change(ing), mutability and materiality we unpack the process of adoption. The study shows that open source software has certain facets; code, community, coordination mechanisms, license and documentation. Each facet is not stable; indeed, it is changing and mutable. This creates possibilities, potential but also recalcitrance, and barriers. The interesting point of departure of our study is how open source software a much touted transparent and open phenomenon is by its nuanced and layered mutability able to make the process and practices surrounding it less visible. It concludes with clear policy recommendations developing from this research that could help to make open source adoption more sustainable in the public sector. (c) 2015 Elsevier Inc.

The Visualization platform is scalable and can be applied to urban environments, provided open source files be used; CityGML is an open standard based on a geometry -driven Ontology which is compatible with this approach. We illustrate our results with examples concerning to very damaged churches and a urban district of Segovia (World Cultural Heritage). Their connection with appropriate database eases the building evolution and interventions tracking. We have incorporated some preliminary examples to illustrate Advanced Visualization Tools and architectural e-Learning software platform which have been created for assessing conservation and restoration tasks in very damaged buildings. First version of the Advanced Visualization application has been developed in the framework of ADISPA Spanish Project Results.

Agent based model is a type of computing model that can simulate the behaviors and interactions between autonomous entities. With agent based models, we can simulate the self-organization process of open source software development by simulating contributors' behaviors. Therefore, we design an agent-based simulation system for open source software development, which are implemented with the Java Agent Development framework. In experiments, we obtain the simulation results by inputting historical behavior information of open source repositories on GitHub. Then we compare the results of various models. Finally, by adjusting input parameters for issue resolution process, we analyze the impact of these parameters, which shows this system also helps understand how to control the open source software development process.","2020","2025-04-25 15:29:13","2025-04-25 15:29:13","","164-170","","","","","","","IEEE World Congress on Services","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 2378-3818","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

South Africa is Botswana's neighbor and both countries are leading economies in Africa. Design/methodology/approach - The paper draws on a survey that was carried out in information communication technology (ICT)-intensive government ministries in Botswana in May 2008. The study sought to establish availability of policy framework, level of usage of open source software, government support, motivations for implementing open source software in government, availability of skills, attitude of it managers in government toward open source software and challenges of open source software deployment in the public sector. The population of the study consisted of information technology (IT) managers who were purposively selected from ICT-intensive government ministries and interviewed. The study was extended to cover South Africa through review of literature on the same issues as those studied in Botswana. Findings - Compared with other countries in developed and developing countries including South Africa, there is limited use of open source software in the public sector in Botswana. However, IT managers in government of Botswana demonstrate a positive attitude toward open source software, and seem to have adequate understanding of its potential benefits. Comparatively, South African government provides support for harnessing open source software; awareness among top government officials is high and attitude toward open source software seems positive; skills are generally available and hardly any challenges of using open source software were identified. Research limitations/implications - This study was limited to purposively selected government ministries which are ICT-intensive in Botswana, while for South Africa, the study was based on secondary sources of data and focused on deployment of open source software in government agencies. Practical implications - Despite the increasing deployment of open source software in government across the world, the Botswanan government is yet unlikely to put in place an enabling open source software policy to harness the potential of the Software. Originality/value - Open source software deployment in government across the world is gaining momentum purportedly to enhance universal access, reduce costs associated with commercial software bridge the digital divide, grow indigenous IT skills, etc. Botswana and South Africa are the economic frontline states in Africa, and their leadership role in this matter among counterparts on the African continent is pertinent.","2010","2025-04-25 15:29:13","2025-04-25 15:29:13","","63-80","","1","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand.

The current mobile platform market is witnessing a platforms-war with big players such as Apple, Google, Nokia and Microsoft in a major role. An important aspect of today's mobile platform market is the contributions made through open source initiatives which promote innovation. This paper gives an insight into the open-source software strategies of the leading players and its implications on the market. It first gives a precise overview of the past leading to the current mobile platform market share state. Then it briefs about the open-source software components used and released by Apple, Google and Nokia platforms, leading to their mobile platform strategies with regard to open source.

However, this task is far from trivial, since such projects are sometimes not easy to understand and adapt to target systems, whereas at the same time the reusable assets are not obvious to identify. In this study, we assess open source software projects, with respect to their reusability, i.e., the easiness to adapt them in a new system. By taking into account that domain-specific reuse is more beneficial than domain-agnostic; we focus this study on identifying the application domains that contain the most reusable software projects. To achieve this goal, we compared the reusability of approximately 600 OSS projects from ten application domains through a case study. The results of the study suggested that in every aspect of reusability, there are different dominant application domains. However, Science and Engineering Applications and Software Development Tools, have proven to be the ones that are the most reuse-friendly. Based on this observation, we suggest software engineers, who are focusing on the specific application domains, to consider reusing assets from open source software projects. (C) 2017 Elsevier Inc.

The potential for sustainability of such tools needs to assessed prior to any organisational adoption.

For the company it was interesting to explore the two Open Source modelling tools Topcased and Papyrus for potential adoption. The focus for our case study is on assessing the health of the ecosystems for the two investigated Open Source projects by means of quantitative analysis of publically available data sources about Open Source projects. The health of ecosystems is an important prerequisite for a long term sustainable OSS (Open Source Software) tool-chain in the MDD area, which can aid strategic decision making for potential adoption within a company context. We have established details on the extent to which developers and users are active in two specific OSS ecosystems, and identified organisational influence for both ecosystems. We find that the investigated tools are promising regarding the health of their ecosystems, and a natural next step for the company would be to proceed with a pilot study in order to analyse the effectiveness of the investigated tools in company contexts.","2011","2025-04-25 15:29:13","2025-04-25 15:29:13","","348+","","","365","","","","IFIP Advances in Information and Communication Technology","","","","CAPES, Minist Educ, Coordinat Improvement Higher Educ Personnel; CNPQ, Minist Sci & Tecnol, Natl Council Sci & Technol Dev; FAPESB, State Bahia Res Agcy; Petrobras","","","","","","","","","ISSN: 1868-4238","","","","","","Hissam, SA; Russo, B; Neto, MGD; Kon, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making `good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.","2009","2025-04-25 15:29:13","2025-04-25 15:29:13","","51-71","","1","74","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for-profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 15:29:14","2025-04-25 15:29:14","","369-402","","2","30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such a scenario sometimes leads to a situation in which while an architect claims the use of a secure architecture in the form of some tactic, the corresponding source code does not support the claim. To bridge this gap, the first critical step is to verify whether the source code reflects at least some of the structural or behavioral features required for a tactic. In this study, we examine the extent of this discrepancy between an architect's vision of what security tactics need to be adopted in the software and the actual implementation. We accomplish this research goal by 1) exploring an architect's intention to use security tactics, 2) checking whether the tactic is manifested in the design, and finally 3) recovering the evidence of efforts to implement the design in the source code. To avoid limitations to accessing documentation and source code, we use open source projects to conduct our research.","2016-09","2025-04-25 15:29:14","2025-04-25 15:29:14","","1195-1204","","3","65","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open Source Software (OSS) furnishes a valuable source of realistic, sizeable projects for inculcating the appreciation and skills involved in code comprehension and evolution. This paper describes experiences and lessons learnt in using OSS projects to teach an introductory, sophomore/junior-level SE course with an emphasis on comprehension, maintenance, and evolution. Students' reactions and undertakings, acquired through participant observation and homework assignments, suggest that OSS can meaningfully illustrate comprehension and evolution difficulties. Finally, it describes the characteristics of OSS projects that are conducive to highlighting maintenance challenges.","2013","2025-04-25 15:29:14","2025-04-25 15:29:14","","","","","","","","","Frontiers in Education Conference","","","","Inst Elect & Elect Engineers Comp Soc; Amer Soc Engn Educ, Educ Res Methods Div; Inst Elect & Elect Engineers; Inst Elect & Elect Engineers Educ Soc","","","","","","","","","ISSN: 0190-5848","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Firstly, the OSS community developed the institutional innovation of OSS licenses enabling OSS software to survive as a common property. Secondly, these licenses are mainly enforced by pro-socially motivated contributors. We characterize the conditions under which OSS communities develop and sustain pro-social commitments. We point out the vulnerability of these conditions to developments in patent legislation.

While these GDM processes have attracted the attention of researchers, the rationale behind decisions, that is, how decisions are made that enhance the OSS, have not received much attention. This work bridges this gap by extracting these rationales from a large open source repository comprising 1.55 million emails available in Python development archives. This work makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs information retrieval, natural language processing, and heuristics-based techniques. Using these techniques, it extracts the rationale behind specific decisions (for example, whether a new module was added based on core developer consensus or a benevolent dictator's pronouncement). This work unearths 11 such rationales behind decisions in the Python community and thus makes a knowledge contribution. It also analyzes the prevalence of these rationales across all PEPs and three sub-types of PEPs: Process, Informational, and Standard Track PEPs. The effectiveness of our contributions has been positively evaluated using quantitative and qualitative approaches (e.g., comparison against baselines for rationale identification showed up to 47% improvement in the most conservative case, and feedback from the Python steering committee showed the accurate identification of rationales respectively). The approach proposed in this work can be used and extended to discover the rationale behind decisions that remain hidden in communication repositories of other OSS projects, which will make the decision-making (DM) process transparent to stakeholders and encourage decision-makers to be more accountable.","2024-04","2025-04-25 15:29:14","2025-04-25 15:29:14","","","","4","36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although developers may find useful software assets to reuse from OSS for their projects, they usually experience difficulties in solving problems that occur while integrating the assets to their own software. We investigated data from major open source environments such as Sourceforge. net and GitHub, and learned that there is a common pattern of solving reuse-related problems in OSS. To analyze the pattern in detail, we have developed an ontological model to formally represent the symptoms and causes of the reuse-related problems, and the correlations between them. Based on this model, we collected data from Sourceforge. net, and built a knowledge base for the most common problem type. We extracted the core types of symptoms and causes for the problem type and calculated the number of correlations between the types of symptoms and causes. We found that there exist correlations between the symptoms and causes that are extracted from the discussion threads for the problem type, and about 60% of them are statistically significant. We also conducted a study to understand the effective timing of recommending solutions to the developers by analyzing the recall rates of finding the causes of the problems in a timeline. We figured that most of the important causes of a problem are discussed at the beginning of the forum discussion. This leads us to the conclusion that recommending the causes of a problem early by using our knowledge framework may help developers spend less amount of time to solve the problem (around 50% less time than solving the problem without using our framework).","2015-08","2025-04-25 15:29:14","2025-04-25 15:29:14","","1077-1103","","6","25","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The approach itself, however, has never been studied. In this paper we take the first step to formalising the Debased architecture assessment of Java Open Source software. We present two aggregate measures: average normalised distance from the train sequence D, and parameter of the fitted statistical model a. Applying these measures to a carefully selected collection of benchmarks we obtain a set of reference values that can be used to assess quality of a system architecture.

Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender-balanced, women-friendly and inclusive workplace certainly would benefit from a more diverse environment.

Here we show that, while initially developed to analyze hyperspectral two-dimensional (spatial) maps, this tool can be beneficial as well to anyone interested in measuring spectral variations over one or two dimensions, these dimensions being time, temperature, and so on. Different possibilities offered by the software (preprocessing, simultaneous analysis of replicas, of different conditions, ROT calculation, multivariate analysis, determination of reaction rate constant and of Arrhenius plot) are illustrated with two examples. The first example is the Fourier transform infrared spectroscopy (FTIR) follow-up of the saponification of oil by lead compounds. The disappearance of reagent (oil) and formation of products (lead carboxylates and glycerol) can be easily followed and quantified.

In this paper, we conducted a 661-participants online survey to investigate the perspectives and practices of developers towards OSS licenses. The user study revealed an indeed need for an automated tool to facilitate license understanding. Motivated by the user study and the fast growth of licenses in the community, we propose the first study towards automated license summarization. Specifically, we released the first high quality text summarization dataset and designed two tasks, i.e., license text summarization (LTS), aiming at generating a relatively short summary for an arbitrary license, and license term classification (LTC), focusing on the attitude inference towards a predefined set of key license terms (e.g., Distribute). Aiming at the two tasks, we present LiSum, a multi-task learning method to help developers overcome the obstacles of understanding OSS licenses. Comprehensive experiments demonstrated that the proposed jointly training objective boosted the performance on both tasks, surpassing state-of-the-art baselines with gains of at least 5 points w.r.t.

However, to strive as a new kind of organization, open source must provide production gains, which in turn should be measurable. The open source movement is particularly interesting to study for this reason. Here, we confront and discuss two contrasting views, which were reported in the literature recently. On the one hand, Sornette et al. (2014) uncovered a superlinear production mechanism, which quantifies Aristotle adage: “the whole is more than the sum of its parts”. On the other hand, Scholtes et al. (2016) found opposite results, and referred to Maximilien Ringelmann, a French agricultural engineer (1861-1931), who discovered the tendency for individual members of a group to become increasingly less productive as the size of their group increases (Ringelmann, 1913). Since Ringelmann, the topic of collective intelligence has interested numbers of researchers in social sciences and social psychology (Woolley et al., 2010), as well as practitioners in management aiming at improving the performance of their team (Woolley et al., 2015). In most research and practice case studies, the Ringelmann effect has been found to hold, while, in contrast, the superlinear effect found by Sornette et al. is novel and may challenge common wisdom (Sornette et al., 2014). Here, we compare these two theories, weigh their strengths and weaknesses, and discuss how they have been tested with empirical data. We find that they may not contradict each other as much as was claimed by Scholtes et al. (2016). (C) 2019 Elsevier B.V.

Some countries have successfully created extensive information technology infrastructures, yet software use continues to be reliant on pirated sources. The experiences of licensing regulation violations and increasing virus attacks indicate that part of the problem is a consequence of dependencies created by the use of proprietary software within resourcescarce economies. Recent growth in the use of free and open-source software (FOSS) by various public-and private-sector agencies suggests an alternative path to software self-suffciency for a resource-scarce country like Cuba. There is, however, an interesting background to current software use within Cuba that makes it unique among several less-developed countries. Apart from the well-known advantages, FOSS use could be essential to shape the future scenario of Cuba. The present paper first delineates some of the Cuban background, basically characterized by lack of freedom in technology ownership and access to external information. The potential of FOSS use within existing conditions in Cuba is then analyzed. Finally, conclusions are provided on the basis of a survey carried out in Cuba, arguing that there needs to be stronger political will to reduce gaps between goals and implementation reality to achieve intrinsic advantages of FOSS use successfully.","2006","2025-04-25 15:29:15","2025-04-25 15:29:15","","1-17","","1","3","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To begin with, the article defines the term “source code” in reference to software” and it also explains the terms “open source” and “free software.” Moreover, it introduces the definition of Free/Open-Source Software (FOSS). In the following part of the article, Konat offers a microeconomic analysis of “strategic forking” to determine the motives guiding software engineers taking part in FOSS projects. The problem is discussed from the perspective of the theory of public goods, the demand-side approach to innovation, and other theories concerned with issues such as “hackers' ethic” and “ego boosting.” Konat pays special attention to describing the “strategic forking” phenomenon with the use of classical microeconomic and enterprise theory tools developed by researchers Jean Tirole and Josh Lerner. The author follows up with a comprehensive analysis of strategic forking as a key to explaining a fundamental discrepancy in the assessment of the motives that guide programmers taking part in the development of open-source software. The analysis focuses on the definition of strategic forking, the conditions determining this trend and its direct causes. Konat also looks at the implications of strategic forking and the factors due to which this approach has not become more widespread around the world. The article closes with a review of issues that require further analysis, according to Konat. These include the issue of software distribution.","2008-10","2025-04-25 15:29:15","2025-04-25 15:29:15","","23-43","","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The FL capability is especially important to domains such as biomedicine and smart grid, where data may not be shared freely or stored at a central location because of policy regulations. Thanks to the capability of learning from decentralized datasets, FL is now a rapidly growing research field, and numerous FL frameworks have been developed. In this work we introduce APPFL, the Argonne Privacy-Preserving Federated Learning framework. APPFL allows users to leverage implemented privacy-preserving algorithms, implement new algorithms, and simulate and deploy various FL algorithms with privacy-preserving techniques. The modular framework enables users to customize the components for algorithms, privacy, communication protocols, neural network models, and user data. We also present a new communication-efficient algorithm based on an inexact alternating direction method of multipliers.

Although the concept of freedom is mostly prominent with the OSS innovation process, less than 2% of the contributors are women in this male-dominated area. Minorities, including women, are often ignored in its process. This paper presents the case of lack of participation from women in the OSS innovation process. Lack of participation and contributions from women in OSS innovation creates an imbalanced population in the OSS-based knowledge demography and an unbalanced proportion of gender distribution. Based on a comprehensive review, this paper aims to suggest a Constructivist-Technofeminist-OSS Innovation Process framework for understanding female contributions in OSS innovation, not only from a singular point of technical view, but also from social constructivist and feminist perspectives.","2012","2025-04-25 15:29:15","2025-04-25 15:29:15","","113-129","","","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is growing rapidly and gaining market share in both industry (e. g., Linux and Mozilla) as well as academia (e.g, Moodle, Greenfoot, and Drupal). OSS projects have a culture built on volunteer participation to support software development. Computing degree programs desire to involve students in large-scale software projects to provide students with real-world experience and an understanding of the issues found in large, complex software projects. Involving computing students in OSS projects serves both the OSS community by providing development resources for the project while also serving the academic community by providing access to large software projects in which students can gain experience. However, the marriage of student and OSS project presents some challenges including identification of approachable OSS projects, creation of appropriate educational infrastructure, evaluation and grading, and more. Panelists will address the factors that contribute to student success in an OSS project.","2010","2025-04-25 15:29:15","2025-04-25 15:29:15","","","","","","","","","Frontiers in Education Conference","","","","IEEE","","","","","","","","","ISSN: 0190-5848","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to consider the effect of each software component on the reliability of an entire system, we propose a new approach to user-oriented software reliability assessment by creating a fusion of neural network and software reliability growth modeling. In this paper, we show application examples of component-oriented software reliability assessment based on neural network and software reliability growth modeling for the OSS.

These conflicts may induce developer turnover intention towards the organization and the OSS community. This research seeks to identify identification-related determinants that drive turnover intention by surveying Linux kernel developers (N = 321).

We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially influence how a new OSS project chooses among such licenses and how the experiences of the project manager of a new OSS project with particular licenses affects its susceptibility to this social influence. We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Our results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its inter-project social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. We also find that managers of new projects who have been members of more successful prior OSS projects and who have greater depth and diversity, of experience in the OSS community are less susceptible to social influence. Finally, we find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license. These results have implications for research on innovation adoption and diffusion, open source software licensing, and the governance of economic exchange.","2013-09","2025-04-25 15:29:15","2025-04-25 15:29:15","","539-560","","3","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this position paper, we draw attention to another perspective: scientific insight itself is a complex and collaborative artifact under continuous development and in need of continuous quality assurance, and as such, has many parallels to software artifacts. Considering current calls for more open, collaborative and reproducible science; increasing demands for public accountability on matters of scientific integrity and credibility; methodological challenges coming with transdisciplinary science; political and communication tensions when scientific insight on societally relevant topics is to be translated to policy; and struggles to incentivize and reward academics who truly want to move into these directions beyond traditional publishing habits and cultures, we make the parallels between the emerging open science requirements and concepts already well-known in (open-source) software engineering research more explicit. We argue that the societal impact of software engineering expertise can reach far beyond the software engineering research community, and call upon the community members to proactively help driving the necessary systems and cultural changes towards more open and accountable research.","2023","2025-04-25 15:29:15","2025-04-25 15:29:15","","150-156","","","","","","","International Conference on Software Engineering-Software Engineering in Society Track","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc","","","","","","","","","ISSN: 2832-7608","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer. Finally, we develop a committer-identification model to assist OSS projects identifying future committers.","2014","2025-04-25 15:29:16","2025-04-25 15:29:16","","47-56","","","","","","","International Conference on Quality Software","","","","IEEE Reliabil Soc; UT Dallas; IEEE Comp Soc","","","","","","","","","ISSN: 1550-6002","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Defined as the effort spent to re-do some work, rework implies big costs given the fact that the time spent on rework does not count to the improvement of the project. Predicting and controlling rework causes is a valuable asset for companies, which maintain closed policies on choosing team members and assigning activities to developers. However, a trending growth in development consists in Open Source Software (OSS) projects. This is a totally new and diverse environment, in the sense that not only the projects but also their resources, e.g., developers change dynamically. There is no guarantee that developers will follow the same methodologies and quality policies as in a traditional and closed project. In such world, identifying rework causes is a necessary step to reduce project costs and to help project managers to better define their strategies. We observed that in real OSS projects there are no fixed team, but instead, developers assume some kind of auction in which the activities are assigned to the most interested and less-cost developer. This lead us to think that a more complex auctioning mechanism should not only model the task allocation problem, but also consider some other factors related to rework causes. By doing this, we could optimise the task allocation, improving the development of the project and reducing rework. In this paper we presented MAESTROS, a Multi-Agent System that implements an auction mechanism for simulating task allocation in OSS. Experiments were conducted to measure costs and rework with different project characteristics. We analysed the impact of introducing a Q-learning reinforcement algorithm on reducing costs and rework. Our findings correspond to a reduction of 31% in costs and 11% in rework when compared with the simple approach. Improvements to MAESTROS include real projects data analysis and a real-time mechanism to support Project Management decisions.","2016","2025-04-25 15:29:16","2025-04-25 15:29:16","","61-73","","","616","","","","Studies in Computational Intelligence","","","","","","","","","","","","","ISSN: 1860-949X","","","","","","Novais, P; Camacho, D; Analide, C; Seghrouchni, AE; Badica, C","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Traditionally, RE has been considered as a centralized, collocated, and phase-specific process. However, in open-source software (OSS) development environment, the core RE activities are iterative and dynamic and follow a rather decentralized software engineering paradigm. This crosscutting characteristic of open-source RE can be conceptualized using the “Twin Peaks” model that weaves RE together with software architecture. Although many weaving mechanisms have been proposed in recent years, lack of theoretical underpinning limits a mechanism's applicability and usefulness in different scenarios. In this research proposal, we hypothesize stakeholders' social interaction as an ecologically valid weaving mechanism of the “Twin Peaks” in open-source RE. We further outline a concrete research plan to examine the generalizability of this weaving mechanism for three activities: requirements identification, requirements implementation, and creativity in RE. Carrying out this research plan will enable us to gain valuable insights to generate guidelines for enhancing software engineering practice in relevant areas.","2014","2025-04-25 15:29:16","2025-04-25 15:29:16","","467-472","","","","","","","International Requirements Engineering Conference","","","","IEEE; Iowa State Univ, Coll Liberal Arts & Sci; VISITBLEKINGESE; BLEKINGE TEKNISKA HOGSKOLA; CISCO; LANSSTYRELSEN BLEKINGE LAN; VISITKARLSKRONA","","","","","","","","","ISSN: 2332-6441","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process. In detail, we analyze what review feedbacks encourage a contributor to continue with OSS project. Using a Qt project dataset, we understand review feedback which affected contribution period of the developer.","2017","2025-04-25 15:29:16","2025-04-25 15:29:16","","571-572","","","","","","","","","","","IEEE; Tech Council Software Egng; IEEE Comp Soc; Alpen Adria Univ Klagenfurt","","","","","","","","","","","","","","","Pinzger, M; Bavota, G; Marcus, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With respect to Java, divergence is where possible avoided ex ante, whereas for Linux divergence is foremost reduced ex post. The conclusion discusses this difference and the implications of both types of coordination in respect to interoperability. (c) 2004 Elsevier B.V.

The naturally evolving structure of collaborative relationships among software developers is a major distinction between the OSS development model and the traditional development model. Conventional statistical methods that focus on individual cases and their attributes cannot properly inform the management of the naturally evolving collaborative relationships in open source project. We emphasize social network analysis as a method especially suitable for management of open source development projects, because it focuses on relations among individuals rather than attributes of individual cases. We show how open source development can be represented as a collaboration network graph and how the network can be characterized by various network structure metrics. We present four metrics as a starting point size, centralization, density and clusterness; that are most useful in revealing collaborative relationships in OSS development process. We discuss how to generate collaboration network for OSS projects and how to calculate the metrics. We further describe how these metrics can assist in effective management of open source software development process.

However, a balance should be considered between the software cost and the cost of its technical support and reliability. In this article, a maintenance system for wind farms will be presented. It is connected to an information system for maintenance, called SNIFF (Terology Integrated Modular System) as a general base to manage the assets and as a support strategic line to the evolution of this system, which incorporates on-condition maintenance modules, and the support to the research and development done around this theme. The SMIT system is based on a TCP/IP network, using a Linux server running a PostgreSQL database and Apache web server with PHP, and Octave and R software for numerical analysis. Maintenance technicians, chiefs, economic and production management personnel can access SMIT database through SMIT clients for Windows. In addition, this maintenance system for wind systems uses also special low cost hardware for data acquisition on floor level. The hardware uses a distributed TCP/IP network to synchronize SMIT server master clock through Precision Time Protocol. Usually, the manufactures construct, deploy and give the means for the suppliers to perform the wind system's maintenance. This is a very competitive area, where companies tend to hide the development details and implementations. Within this scenario, the development of maintenance management models for multiple wind equipments is important, and will allow countries to be more competitive in a growing market.

Often this takes the form of company employees devoting their time to contribute code to the efforts of projects in these communities. Ideology has traditionally served to motivate, coordinate, and guide volunteer contributions to OSS communities. As employees represent an increasing proportion of the participants in OSS communities, the role of OSS ideology in guiding their commitment and code contributions is unknown. In this research, we argue that OSS ideology misfit has important implications for companies and the OSS communities to which their employees contribute, since their engagement in such communities is not necessarily voluntary. We conceptualize two different types of misfit: OSS ideology under-fit, whereby an employee embraces an OSS ideology more than their coworkers or OSS community do, and OSS ideology over-fit, whereby an employee perceives that their coworkers or OSS community embrace the OSS ideology more strongly than the employee does. To develop a set of hypotheses about the implications of these two types of misfit for employee commitment to the company and commitment to the OSS community, we draw on self-determination theory. We test the hypotheses in a field study of 186 employees who participate in an OSS community. We find that OSS ideology under-fit impacts the company and the community in the same way: it decreases employee commitment to the company and commitment to the OSS community. In contrast, we find that OSS ideology over-fit increases commitment to the company but decreases commitment to the OSS community. Finally, we find that employees' commitment to their company reinforces the impact of their commitment to the OSS community in driving ongoing code contributions. This provides a holistic view of OSS ideology and its impacts among an increasingly pervasive yet understudied type of participant in OSS research. It provides insights for companies that are considering assigning their employees to work in OSS communities as well as for OSS communities that are partnering with these companies.","2018-12","2025-04-25 15:29:17","2025-04-25 15:29:17","","1069+","","4","42","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving.

However, the practice of report-back and the content shared is often limited by the time-intensive process of personalizing reports. Software tools that automate creation of individualized reports have been built for specific studies, but are largely not open-source or broadly modifiable. We created an open-source and generalizable tool, called the Macro for the Compilation of Report-backs (MCR), to automate compilation of health study reports. We piloted MCR in two environmental exposure studies in Massachusetts, USA, and interviewed research team members (n = 7) about the impact of MCR on the report-back process. Researchers using MCR created more detailed reports than during manual report-back, including more individualized numerical, text, and graphical results. Using MCR, researchers saved time producing draft and final reports. Researchers also reported feeling more creative in the design process and more confident in report-back quality control. While MCR does not expedite the entire report-back process, we hope that this open-source tool reduces the barriers to personalizing health study reports, promotes more equitable access to individualized data, and advances self-determination among participants.","2021-06","2025-04-25 15:29:17","2025-04-25 15:29:17","","","","11","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In OSS, sharing the experiences of solving similar problems among developers usually plays an important role in reducing problem-solving efforts. We analyzed how developers interact with each other to solve problems in OSS, and found that there is a common pattern of exchanging information about symptoms and causes of a problem. In particular, we found that many problems involve multiple symptoms and causes and it is critical to identify those symptoms and causes early to solve the problems more efficiently. We developed a Bayesian network based approach to semiautomatically construct a knowledge base for dealing with problems, and to recommend potential causes of a problem based on multiple symptoms reported in OSS. Our experiments showed that the approach is effective to recommend the core causes of a problem, and contributes to solving the problem in an efficient manner. (C) 2016 Elsevier Inc.

The authors suggest that the new paradigm of open innovation may impact a firm's adaptability and responsiveness under conditions of environmental flux. However, extending innovation capacity by opening the innovation process poses major challenges for firms. The aims of this study are to explore the characteristics of open innovation activity and to contemplate the role of strategic flexibility in the design of business models based upon open innovation. Design/methodology/approach - The study draws upon a qualitative research approach through a longitudinal case study in the field of open source software (OSS). The empirical case illustrates how an OSS firm utilizes signals in its environment to flexibly alter its business model. Findings - A business model that embodies open innovation raises dilemmas between open and closed innovation paradigms. However, the authors' case highlights that an ambidextrous approach that combines market orientation with the principles of open innovation increases profitability, shortens time to market through effective market access, and enhances innovation capability. Research limitations/implications - The results have profound implications for industrial marketers, managers, management consultants and business educators. They can use the insights gleaned from this research to guide the development of business models that involve open innovation. The results indicate that firms involved in open innovation need reactive strategic flexibility to cope with the environmental diversity and variability. However, this study analyzes a single case in the field of OSS and one should be cautious when generalizing the findings. Originality/value - This paper improves the understanding of the relationship between flexibility and market orientation. It combines two areas that have previously been discussed separately, i.e. market orientation and open innovation.","2012","2025-04-25 15:29:17","2025-04-25 15:29:17","","1368-1388","","10","46","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The number of articles available and the number of tracks or workshops on this topic in most relevant IS Conferences is high. The usability of Open Source Software has been scarcely considered until few years ago, probably due to the particular role that the user has in such a development environment. In Open Source software development, users and developers are not so different. Anyhow, the diffusion of the Open Source software outside the development community contributes to sharpen the distinction among these two groups that are no longer equivalent. This circumstance has contributed to increase the interest on usability of Open Source software. Nevertheless, studies on end-users in Open Source contexts are still young. This paper introduces a pilot study on end user's perception of Open Source software. The aim of this pilot study is to identify how the end user perceives the Open Source software (in terms of Usability, Functionality, Reliability, Efficiency and Quality in Use).","2010","2025-04-25 15:29:17","2025-04-25 15:29:17","","549+","","","","","","","","","","","Assoc Informat Syst, Italian Chapter","","","","","","","","","","","","","","","DAtri, A; Sacca, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A prime example for this phenomenon is open source software (OSS) development, where multiple actors contribute to a public good, which is also integrated into company-owned software products. Despite the importance of aligning community work on the public good with own in-house development efforts, firms have limited options to directly control the OSS project or the project's outcome. This research reflects on resource deployment control, a control mode in which firms assign own developers to work for an OSS project to influence the OSS project, and tests hypotheses on individual developer levels. Design/methodology/approach This research tests the effect of perceived resource deployment control on opinion leadership by analyzing employed Linux kernel developers. Findings The findings show that developers who perceive being assigned to an OSS project to enact control also exhibit opinion leadership. This research also investigates boundary conditions such as the OSS business model a firm operates and the reputation developers assign to the developers' employer. Originality/value This research is the first that is devoted to resource deployment control, and the research closes with a discussion of implications for control theory and the management of innovation beyond firm boundaries.","2023-05-04","2025-04-25 15:29:17","2025-04-25 15:29:17","","1645-1668","","4","36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A preliminary study was done to explore the state of OSS implementation among government agencies since the launch of the Malaysian Public Sector OSS Master Plan on July 16, 2004. Semi-structured face-to-face interviews using open-ended questions were conducted with IT managers and IT officers in the Northern Region of Peninsular Malaysia. The preliminary study aimed at investigating the usage of OSS and proprietary software, the level of OSS utilisation, the level of OSS knowledge and training of ICT and non-ICT staff, software development and acquisition model, internal OSS manpower capabilities and skills, the user's perception of the advantages of OSS, the user's perception of the risks of OSS, and the problems or barriers in OSS implementation. The results of interviews show that there are many problems or barriers in OSS implementation, e.g. lack of internal OSS expertise, lack of OSS policy, and lack of top management support. Therefore, this study will test the hypotheses on the success factors to OSS implementation in the public sector and to propose a framework for successful OSS implementation in the Malaysian Public Sector. A quantitative approach using survey method via questionnaire will be performed to answer the research question where simple random sampling will be used.

According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at Source Forge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects.","2010","2025-04-25 15:29:17","2025-04-25 15:29:17","","179-210","","3","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, a community-driven wind turbine baseline controller, the Delft Research Controller (DRC), is presented. The DRC is applicable to high-fidelity simulation software that uses the DISCON controller interface. The controller distinguishes itself by the variety of available control and estimation implementations, its ease of use, and the universal applicability to wind turbine models. Secondly, in the wake of the DRC, the SimulinkDRC graphical controller design and compilation environment has been developed. Users having access to Simulink can benefit from the convenient way of controller development the tool provides. Finally, the FASTTool has been developed for educational purposes, by focusing on the graphical aspect of wind turbine (controller) design. The tool simplifies interaction with the advanced FAST simulation software, by comprehensive visualizations and analysis tools.

OpenIFEM is a C++ implementation of the modified immersed finite element method (mIFEM) to solve fluid-structure interaction (FSI) problems. This software is modularly built to perform multiple tasks including fluid dynamics (incompressible and slightly compressible fluid models), linear and nonlinear solid mechanics, and fully coupled fluid-structure interactions. Most of open-source software packages are restricted to certain discretization methods; some are under-tested, under-documented, and lack modularity as well as extensibility. OpenIFEM is designed and built to include a set of generic classes for users to adapt so that any fluid and solid solvers can be coupled through the FSI algorithm. In addition, the package utilizes well-developed and tested libraries. It also comes with standard test cases that serve as software and algorithm validation. The software can be built on cross-platform, i.e., Linux, Windows, and Mac OS, using CMake. Efficient parallelization is also implemented for high-performance computing for large-sized problems. OpenIFEM is documented using Doxygen and publicly available to download on GitHub. It is expected to benefit the future development of FSI algorithms and be applied to a variety of FSI applications.","2019","2025-04-25 15:29:18","2025-04-25 15:29:18","","91-124","","1","119","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS permits users to access source code for assessment, amendment, and redistribution, which offers low dependency on a vendor without license or maintenance cost. This paper investigates and analyzes OSS adoption factors for “critical IT infrastructure” by conducting a comprehensive review of the relevant literature. Furthermore, this paper proposes a framework that can help the critical IT industry to have increased confidence in OSS. The proposed framework utilizes the organizing logic of the Technology, Organization, and Environment (TOE) framework, recommends factors that were recognized by critically scrutinizing the studies found in the available literature. To validate the framework, a questionnaire-based survey was conducted targeting IT experts in critical sectors. The data integrity of survey results was analyzed using Cronbach's alpha.

We demonstrate its application with an oil and gas extraction facility in Colombia. OPAL is the first tool to provide direct consideration of the distribution of ecosystem service benefits among people in a mitigation context. Previous biodiversity-focused efforts led to redistribution or loss of ecosystem services with environmental justice implications. Joint consideration of biodiversity and ecosystem services enables targeting of offsets to benefit both nature and society.

Focusing on the Python community, our study examines a “pushed-by-users” design proposal through the discussions occurring in two mailing-lists: one, user-oriented and the other, developer-oriented. To characterize the links between users and developers, we investigate the activities and references (knowledge sharing) performed by the contributors to these two mailing-lists. We found that the participation of users remains local to their community. However, several key participants act as boundary spanners between the user and the developer communities. This emerging role is characterized by cross-participation in parallel same-topic discussions in both mailing-lists, cohesion between cross-participants, the occupation of a central position in the social network linking users and developers, as well as active, distinctive and adapted contributions. The user championing the proposal acts as a key boundary spanner coordinating the process and using explicit linking strategies. We argue that OSS design may be considered as a form of “role emerging design”, i.e. design organized and pushed through emerging roles and through a balance between these roles. The OSS communities seem to provide a suitable socio-technical environment to enable such role emergence. (C) 2007 Elsevier Ltd.

Focusing on OSS, our study qualitatively analyzed social barriers that hindered newcomers' first contributions. We defined a conceptual model composed of 58 barriers including 13 social barriers. The barriers were identified from a qualitative data analysis considering different sources: a systematic literature review; open question responses gathered from OSS projects' contributors; students contributing to OSS projects; and semi-structured interviews with 36 developers from 14 different projects. This paper focuses on social barriers and its contributions include gathering empirical evidence of the barriers faced by newcomers, organizing and better understanding these barriers, surveying the literature from the perspective of the barriers, and identifying new potential research streams.","2015","2025-04-25 15:29:18","2025-04-25 15:29:18","","1379-1392","","","","","","","","","","","Assoc Comp Machinery; ACM SIGCHI; Facebook; Natl Sci Fdn; Microsoft Res; GRAND; Bloomberg; IBM Res; NW Univ; Simon Fraser Univ; SFU Sch Interact Arts & Technol; Google","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Developers of Python are geographically distributed and work online asynchronously. The objective of our study is to understand and to model the dynamics of the OSS design process that takes place in mailing list exchanges. We develop a method to study distant and asynchronous collaborative design activity based on an analysis of quoting practices. We analyze and visualize three aspects of the online dynamics: social, thematic temporal, and design. We show that roles emerge during discussions according to the involvement and the position of the participants in the discussions and how they influence participation in the design discussions. In our analysis of the thematic temporal dynamics of discussion, we examine how themes of discussion emerge, diverge, and are refined over time. To understand the design dynamics, we perform a content analysis of messages exchanged between developers to reveal how the online discussions reflect the “work flow” of the project: it provides us with a picture of the collaborative design process in the OSS community. These combined results clarify how knowledge and artefacts are elaborated in this epistemic, exploration-oriented, OSS community. Finally, we outline the need to automate of our method to extend our results. The proposed automation could have implications for both researchers and participants in OSS communities.

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 7 0 0; 0 0 0 bug reports obtained from the BUGZILLA installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3% with an associated recall of 38.9%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.","2013","2025-04-25 15:29:18","2025-04-25 15:29:18","","1032-1041","","","","","","","","","","","Assoc Comp Machinery; ACM Special Interest Grp Software Engn; IEEE Comp Soc; Tech Council Software Engn","","","","","","","","","","","","","","","Notkin, D; Cheng, BHC; Pohl, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Parametrising such models to conform to the multitude of available experimental constraints is a global nonlinear optimisation problem with a complex fitness landscape, requiring numerical techniques to find suitable approximate solutions. Stochastic optimisation approaches, such as evolutionary algorithms, have been shown to be effective, but often the setting up of such optimisations and the choice of a specific search algorithm and its parameters is non-trivial, requiring domain-specific expertise. Here we describe BluePyOpt, a Python package targeted at the broad neuroscience community to simplify this task. BluePyOpt is an extensible framework for data-driven model parameter optimisation that wraps and standardises several existing open-source tools. It simplifies the task of creating and sharing these optimisations, and the associated techniques and knowledge. This is achieved by abstracting the optimisation and evaluation tasks into various reusable and flexible discrete elements according to established best-practices. Further, BluePyOpt provides methods for setting up both small- and large-scale optimisations on a variety of platforms, ranging from laptops to Linux clusters and cloud-based compute infrastructures.

In this study, we generated the static function-call graphs of several open-source software systems, where functions were the most basic type of interacting elements calling each other. Then, we analyzed the call graphs both visually and topologically using the techniques of complex network analysis. We found the call graphs to reveal scale-free and small-world network properties similar to the findings of the previous studies.

At the same time, many software organizations are applying Scrum software development practices, for productivity and quality gains. Scrum calls for self-organizing teams, in which the development team has total control over its development process. However, OSS projects typically have their own processes and standards, which might not mesh well with a company's internal processes, such as Scrum. This paper presents an experience report from Sony Interactive Entertainment (SIE), where the “toolchain CPU compiler” team directly participates in the “LLVM” OSS project. The team ran into a number of difficulties when using Scrum to manage their development. In particular, the team often failed to complete Scrum sprints where tasks required interaction with the open source community. We look at how the team redefined task flows to alleviate these difficulties, and eventually evolved a highly modified process, dubbed TWINS (This Workflow Is Not Scrum). We assess the revised process, and compare it to other established agile methods, finding it bears a strong resemblance to Scrumban (the SIE team was not aware of Scrumban previously). The TWINS framework presented here may help other organizations who develop software in-house and engage in OSS projects, to gain the best of both worlds.","2019","2025-04-25 15:29:18","2025-04-25 15:29:18","","24-33","","","","","","","","","","","IEEE; ACM; IEEE Comp Soc","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity. (C) 2019 The Authors.

One way to achieve these ends is to implement eGovernment using free or open source software (FOSS). This will reduce dependence on software owned by major companies in developed countries. It could also promote an IP generating capacity in developing countries. An examination of the status of free or open source software in developing countries in Southeast Asia reveals that governments in these countries are aware of FOSS and wish to foster its use (but face considerable pressure to use proprietary software). This examination also reveals the presence of small but active groups seeking to develop and promote the use of free or open source software. This article is comprised of a discussion of FOSS (including that suitable for eGovernment), an explanation of the importance of FOSS for developing countries, a justification of government's centrality to the introduction of FOSS and a consideration of policies and initiatives undertaken by governments in developing countries in Southeast Asia.

The greenhouse was equipped with roof and side wall ventilators. The ventilation rate was calculated via an equation where both wind and buoyancy effect were taken into consideration. The goal of this research was to develop an inexpensive system that could be used by the producers as a reliable and accurate tool for measuring environmental parameters inside greenhouses and other agricultural buildings.

Users on Stack Overflow actively revise posted code snippets, sometimes addressing bugs and vulnerabilities. Accordingly, developers that reuse code from Stack Overflow should treat it like any other evolving code dependency and be vigilant about updates. It is unclear whether developers are doing so, to what extent outdated code snippets from Stack Overflow are present in GitHub projects, and whether developers miss security-relevant updates to reused snippets. To shed light on those questions, we devised a method to 1) detect outdated code snippets versions from 1.5M Stack Overflow snippets in 11,479 popular GitHub projects and 2) detect security-relevant updates to those Stack Overflow code snippets not reflected in those GitHub projects. Our results show that developers did not update dependent code snippets when those evolved on Stack Overflow. We found that 2,405 code snippet versions reused in 2,109 GitHub projects were outdated, with 43 projects missing fixes to bugs and vulnerabilities on Stack Overflow. Those 43 projects containing outdated, insecure snippets were forked on average 1,085 times (max. 16,121), indicating that our results are likely a lower bound for affected code bases. An important insight from our work is that treating Stack Overflow code as purely static code impedes holistic solutions to the problem of copying insecure code from Stack Overflow. Instead, our results suggest that developers need tools that continuously monitor Stack Overflow for security warnings and code fixes for reused code snippets and not only warn during copy-pasting.","2024","2025-04-25 15:29:19","2025-04-25 15:29:19","","1083-1101","","","","","","","IEEE Symposium on Security and Privacy","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 1081-6011","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open data standards are co-created in open communities for unifying the exchange of information. The SPDX (R) specification is such an open data standard to explicate and share OSS risk information. The development and subsequent adoption of SPDX raises the questions of how organizations make sense of SPDX when improving their own risk management routines, and of how a community benefits from the experiential knowledge that is contributed back by organizational adopters.

Traditional methods of measuring node influence only consider some topology characteristics of the network, so the results are one-sided. Because there are different interactive behaviors among users in the community, it is necessary to mine more interaction information, so as to give a more comprehensive measure of node influence. In view of this, this paper proposes a method to maximize the node influence of open source software community based on a probability propagation model. Firstly, according to the relationship of users and their interactive records on projects, this paper quantifies the feedback of users on the project from three aspects (i.e. approve, save and modify) and establishes a new probability propagation model between users. Secondly, this paper proposes an algorithm(SIUF) to evaluate users' influence in the open source software community based on the probability propagation model. The algorithm fully considers the interaction behavior of users in the community. In the first stage, the user's own activity is taken as the initial ranking. In the second stage, the influence of neighbor nodes is taken into account, and the SIUF value of nodes is accumulated while the rich club effect is weakened. Finally, the proposed theory and method are applied to GitHub, a typical open source software community, and the correctness and effectiveness of this method are verified from influence spread and speed.","2023-08","2025-04-25 15:29:19","2025-04-25 15:29:19","","2386-2395","","4","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Precision fertilization and irrigation is an effective method to solve this problem. In order to precisely control plant fertilization and irrigation, a monitoring system is designed and implemented using open-source software, loose communication structure, industrial control computer (IPC), programmable logic controller (PLC), and control and monitoring devices. The control command management subsystem of the system's upper computer is built using GoWin IPC, cloud server, mobile devices, and 4G wireless network. Each application running in the upper computer is developed using open-source software such as PostgreSQL, Smobiler, etc. The fertilization and irrigation monitoring subsystem of the lower computer was built using HollySys PLC model LE5107L and different sensors for various data parameters as control units. The system allows real-time remote monitoring and control of agricultural precision fertilization and irrigation through mobile applications, with an average communication delay of 1.45 s between the upper and lower units, and less than 3 s overall, allowing for longterm stable communication. The current system can adapt to the variable environment in the field and has been operating stably in the field for 2 months.

Objectives include opportunities for improving reputation, managing suppliers, managing partners and competitors, and exploiting externally available knowledge and resources. Complexities include risk of loosing control, risk of giving away competitive advantage, risk of creating negative exposure, costs of contributing, and the possibility and need to contribute to an existing or new community.

An alternative to joining an existing HFOSS project community is to participate in a faculty-led HFOSS project. These projects provide the instructor with more control over the learning environment, but often lack an active community outside of the classroom. This paper describes a multi-institutional effort to engage a community of developers in creating humanitarian open source projects to support their on-campus food pantries. Food insecurity on campus has become a national concern and many institutions have, or are starting, food pantries to support the student, staff, and faculty community. Starting a faculty-led HFOSS project involves making decisions not only about the features of the project but also about community norms, tool choices, project development workflow, and inter-institution cooperation. This paper provides an overview of the creation of Libre Food Pantry, a community who is developing a suite of projects that support on-campus food pantries. It describes instances of using Libre Food Pantry's projects in various classroom settings, the lessons learned from these experiences, and the resulting discussions and decisions made by the Libre Food Pantry Coordinating Committee. This process has led to a community dedicated to easing the on-ramp for faculty who want to help their students contribute to an HFOSS project.","2020","2025-04-25 15:29:19","2025-04-25 15:29:19","","441-447","","","","","","","","","","","Assoc Comp Machinery, Special Interest Grp Comp Sci Educ; Assoc Comp Machinery","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To estimate whether a state ofsocio-technical congruenceis achieved, which is associated with software quality and project success, we assess the alignment of collaboration and communication in such software projects in terms ofcoordination requirements. By means of an empirical study on a substantial set of large-scale open-source software projects-the development histories of all projects sum up to over 180 years-we aim at shedding light on this issue. To this end, to take a more semantic view on this phenomenon in comparison to previous work, we do not only identify coordination requirements arising from files and functions only, but also those arising from features. We found that open-source developers fulfill coordination requirements intentionally, but mostly those coordination requirements that arise from coupled source-code artifacts, while they resolve simpler ones independently. Furthermore, neither of the considered abstraction levels of source-code artifacts (files, functions, features) is more suitable to construct coordination requirements with respect to their fulfillment. This finding strongly indicates that features do not play an as important role in the development process as expected and commonly believed by the research community in the area of feature-oriented and feature-driven development. Finally, we identified notable evolutionary trends in the fulfillment of coordination requirements and showed that far-reaching social events (such as organizational issues) have a huge impact on their fulfillment, both negatively and positively. The key findings of our empirical study are that socio-technical relations are important to understand open-source development communities and that the incorporation of different abstraction levels for developer collaboration does yield important insights to further improve the evolution in open-source software projects.","2020-11","2025-04-25 15:29:19","2025-04-25 15:29:19","","4379-4426","","6","25","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Apart from its typical RE process, there is a competing process, external to the firm and inherent to the firm's ecosystem. When trying to impose an agenda in competition with other firms, and aiming to align internal product planning with the ecosystem's RE process, firms need to consider who and how influential the other stakeholders are, and what their agendas are. The aim of the presented research is to help firms identify and analyze stakeholders in OSS ecosystems, in terms of their influence and interactions, to create awareness of their agendas, their collaborators, and how they invest their resources. To arrive at a solution artifact, we applied a design science research approach where we base artifact design on the literature and earlier work. A stakeholder influence analysis (SIA) method is proposed and demonstrated in terms of applicability and utility through a case study on the Apache Hadoop OSS ecosystem. SIA uses social network constructs to measure the stakeholders' influence and interactions and considers the special characteristics of OSS RE to help firms structure their stakeholder analysis processes in relation to an OSS ecosystem. SIA adds a strategic aspect to the stakeholder analysis process by addressing the concepts of influence and interactions, which are important to consider while acting in collaborative and meritocratic RE cultures of OSS ecosystems.","2020-03","2025-04-25 15:29:20","2025-04-25 15:29:20","","115-130","","1","25","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the immense success of several mainstream OSS projects such as Mozilla, Linux, and Apache, a vast majority of such projects fail to sustain their development due to high levels of developer turnover. While existing research in the area has offered a rich foundation, we know little about how developers' perceptions of fit with the project environment may be moderated by the sense of ownership they have toward the project and how it may impact their turnover intentions. Using survey data from 574 GitHub developers, we tested a model to examine the impact of Person-Organization fit and psychological ownership on developers' turnover intentions. Our results suggest that two relevant dimensions of fit, namely, value and demands-abilities fit, negatively impact turnover intentions and that their sense of ownership moderates these effects.","2015","2025-04-25 15:29:20","2025-04-25 15:29:20","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Best practices suggest employing UX Capability Maturity Models (UXCMMs), which often specify an evolutionary plateau toward developing a UX-matured system and quantify organizational UX maturity into maturity levels ranging from no or ad hoc improvement to integrated continuous improvement. Numerous generically developed UXCMMs exist. However, none is created for the FOSS community, and less information is available to support their perfect match. Thus, raise suspicions if they have proper UX maturity influencing factors (UXMIFs) for the FOSS community or measure the right thing. The FOSS community differs from traditional software-developing communities and may have different dynamics and UXMIFs, necessitating unique and new methodologies for their discovery. This study, therefore, aims to identify the FOSS community's UXMIFs and evaluate the community's knowledge of UX maturity-related concepts. Its findings may help future researchers, practitioners, and other FOSS developers to develop UXCMMs exclusive to the FOSS community. The study's design is both qualitative and quantitative. It adopted a systematic literature review, interviews, fuzzy Delphi Method, and thematic analysis to collect and analyze data and present the findings. The study's sample included sixty-two active FOSS projects, fifteen FOSS stakeholders, and twelve UX experts. The outcome shows that 84% of UX experts agreed on the thirty-six FOSS's UXMIFs with threshold d = 0.143 and crisp values greater than alpha-cut = 0.5. User feedback and adopted technologies were ranked first, while learnability and use speed were ranked last.

Our analysis covers 705 official releases and a combined 108years of evolution. We first tried to confirm Lehman's eight laws of software evolution on these projects using statistical hypothesis testing. Our findings indicate that only the laws of continuing change and continuing growth are confirmed for all programs, whereas the other six laws are violated by some programs, or can be both confirmed and invalidated, depending on the laws' operational definitions. Second, we analyze the growth rate for projects' development and maintenance branches, and the distribution of software changes. We find similarities in the evolution patterns of the programs we studied, which brings us closer to constructing rigorous models for software evolution.

For this estimation, often prediction models are used which can be learned from project data. In this paper, an approach for the usage of agent-based simulation for the prediction of software evolution trends is presented. The specialty of the proposed approach lies in the automated parameter estimation for the instantiation of project-specific simulation models. We want to assess how well a baseline model using average (commit) behavior of the agents (i.e., the developers) performs compared to models where different amount of project-specific data is fed into the simulation model. The approach involves the interplay between the mining framework and simulation framework. Parameters to be estimated include, e.g., file change probabilities of developers and the team constellation reflecting different developer roles. The structural evolution of software projects is observed using change coupling graphs based on common file changes. For the validation of simulation results, we compare empirical with simulated results. Our results showed that an average simulation model can mimic general project growth trends like the number of commits and files well and thus, can help project managers in, e.g., controlling the onboarding of developers. Besides, the simulated co-change evolution could be improved significantly using project-specific data.","2021-05","2025-04-25 15:29:20","2025-04-25 15:29:20","","","","1","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Overland flooding, the most common type of flooding event usually occurs when rivers or streams overflow their banks as a result of heavy rainfalls or fast snowmelt. In European Union, flood defence management is an essential part of the integrated water management and the European Commission Directive 2007/60, regarding the estimation and management of the flood risks, states that all the member countries have to achieve flood risks maps till the end of 2013. Flood hazard maps must be created to help the communities in finding out which are the different flood risk areas and to provide public awareness and useful information to local authorities and decisions makers in case of possible flood events. Flood risk areas should be also identified and delimited for future land use and development. The development of risk maps assumes the existence and access to extensive databases, detailed maps and GIS data depots for most of the necessary information, as well as expensive software (i.e. ArcGIS, MIKE) and skilled experts. Unfortunately, these criteria are not always met. This paper presents an alternative method to prepare preliminary floodplain maps, based on the use of Autodesk products and Open Source software. The purpose of the method is to introduce basic satellite image display and processing techniques using open source software and freely available satellite data to allow floodplain maps development without using expensive software and unaffordable data. The method consists in DTM (Digital Terrain Model) generation, rivers and watershed delineation and hydraulic modelling in order to generate floodplain maps.","2013","2025-04-25 15:29:20","2025-04-25 15:29:20","","481+","","","","","","","International Multidisciplinary Scientific GeoConference-SGEM","","","","","","","","","","","","","ISSN: 1314-2704","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently, RR estimating instrumentation is specialized and bulky, therefore unsuitable for remote health monitoring. Previously, RR was estimated using proprietary software that extract surface electrocardiogram (ECG) waveform features obtained at several thoracic locations. However, developing a non-proprietary method that uses minimal ECG leads, generally available from mobile cardiac monitors is highly desirable. Here, we introduce an open-source and well-documented Python-based algorithm that estimates RR requiring only single-stream ECG signals. The algorithm was first developed using ECGs from awake, spontaneously breathing adult human subjects. The algorithm-estimated RRs exhibited close linear correlation to the subjects' true RR values demonstrating an R-2 of 0.9092 and root mean square error of 2.2 bpm. The algorithm robustness was then tested using ECGs generated by the ischemic hearts of anesthetized, mechanically ventilated sheep. Although the ECG waveforms during ischemia exhibited severe morphologic changes, the algorithm-determined RRs exhibited high fidelity with a resolution of 1 bpm, an absolute error of 0.07 +/- 0.07 bpm, and a relative error of 0.67 +/- 0.64%. This optimized Python-based RR estimation technique will likely be widely adapted for remote lung function assessment in patients with cardiopulmonary disease.","2024-01-02","2025-04-25 15:29:20","2025-04-25 15:29:20","","","","1","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It implements two different working modes: exploration, where the impact of decisions may be assessed before making them; and continuous assessment, where risk variables (and their possible consequences on business goals) are continuously monitored and reported to decision-makers. The blackboard-oriented architecture of the platform defines several interfaces for the identified techniques, allowing new techniques to be plugged in.","2015","2025-04-25 15:29:20","2025-04-25 15:29:20","","124-133","","","451","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 2 13; Google","","","","","","","","","ISSN: 1868-4238","","","","","","Damiani, E; Frati, F; Riehle, D; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We draw parallels to the business case for commercial software products (COTS). Compared with COTS, OSS products seem to have several advantages, but based on existing literature and a case study, we develop and discuss the hypothesis that a major barrier may be the “customer's” uncertainty and unfamiliarity with OSS vendor relationships. We find that corporate governance and architecture needs to be accounted for in both COTS and OSS.

Furthermore, we propose the optimal blocking concept to represent the cost of repairing the entire propagation path, in order to measure the severity of the project's vulnerability. As for the purpose of providing effective suggestions on vulnerability repairing, we model the optimal blocking calculation as the network flow minimal separate problem, then calculate the network maximal flux to obtain the key dependencies with risks.

An important open question is related with the investigation of how undergraduate students perceive the relevance of open source software literature. To address this question, we conducted a survey at University of Brasilia (UnB) where 500 undergraduate students were invited to rate the relevance of research ideas contained in papers that were published over a period of ten years. This paper attempts to investigate whether the Open Source Software research produces results considered relevant to undergraduate students. This way we can provide feedback from the students, offering a way to produce useful and, consequently, more disseminated works among Open Source practitioners. To answer about the relevance of available work, we have tackled two questions: one about the scope of the studies and another about the quality perceived by them. For the first one, a systematic mapping was conducted, revealing a set of works composed by a great diversity of results. Than, we applied a Survey in which students could evaluate the relevance of these gathered works. The available open source software research works seem to be very diverse and were considered useful for students that contribute to the Open Source Projects. 77.01% of respondents answered that research conducted in the Open Source Community is relevant and important to the community, as well as to their professional and academic lives.","2019","2025-04-25 15:29:21","2025-04-25 15:29:21","","12-16","","","","","","","","","","","TecnoTRENDS Tecnologia Educac; Google; Univ Fed Bahia, Inst Matematica & Estatistica, Dept Ciencia Computacao","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Efficient maintenance within short release cycles depends highly on the underlying source code structure, in the sense that complex modules are more difficult to maintain. In this paper we attempt to unveil and discuss relationships between maintenance productivity, the structural quality of the source code and process metrics like the type of a release and the number of downloads. To achieve this goal, we developed a Bayesian Belief Network (BBN) involving several maintainability predictors and three managerial indices for maintenance (i.e., duration, production, and productivity) on 20 open source software projects. The results suggest that maintenance duration depends on inheritance, coupling, and process metrics. On the other hand maintenance production and productivity depend mostly on code quality metrics.","2016","2025-04-25 15:29:21","2025-04-25 15:29:21","","32-44","","","472","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 2 13; Software Ctr; Informat & Commun Technol; Business Reg Goteborg","","","","","","","","","ISSN: 1868-4238","","","","","","Crowston, K; Hammouda, I; Lundell, B; Robles, G; Gamalielsson, J; Lindman, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we have developed a grand potential-based nonlinear phase-field model to study the electrodeposition of lithium as relevant for a lithium metal anode, using open-source software package MOOSE. The dynamic morphological evolution under a large/small overpotential is studied in two dimensions, revealing important dendrite growth/stable deposition patterns. The corresponding temporal spatial distributions of ion concentration, overpotential, and driving force are studied, which demonstrate an intimate, dynamic competition between ion transport and electrochemical reactions, resulting in vastly different growth patterns. On the basis of the understanding from this model, we propose a “compositionally graded electrolyte” with higher local ion concentration as a way to potentially suppress dendrite formation. Given the importance of morphological evolution for lithium metal electrodes, widespread applications of phase-field models have been limited in part due to in-house or proprietary software. In order to spur growth of this field, we make all files available to enable future studies to study the many unsolved aspects related to morphology evolution of lithium metal electrodes.","2018-07","2025-04-25 15:29:21","2025-04-25 15:29:21","","1737-1743","","7","3","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A version control system records all information about these changes. Several research studies in the past have studied the historical records of changes of open source software (OSS) projects and found them useful for understanding the software evolution process. However, most of them investigate the distributions of changes types, change size, and change effort in an isolated manner. There is no work, to the best of our knowledge, which takes a combined view of various dimensions of a change. This study examines the change activity in 106 OSS projects from three points of view: change purpose (type), change size, and change effort. The common patterns in change type, change size, and change effort are highlighted using the burst detection technique. The burst detection technique helps in identifying the peaks in the time series and compares them with the peaks of other time series. The results indicate that the change-type activity of OSS projects is significantly related with change effort, and change size for high and moderate-activity clusters. Though for low-activity cluster, this commonality of patterns is not there for all types of changes.","2017-12","2025-04-25 15:29:21","2025-04-25 15:29:21","","329-337","","6","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These efforts aim to identify common elements in the development process between multiple open source software (OSS) projects. However, the complexity inherent to OSSD process modeling puts significant demands on the modeling language. Objective: In this paper, we propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. Method: We investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. DEMO models were constructed to describe the NetBeans Requirements and Release process. In addition, the quality of these DEMO models was evaluated using a quality framework for conceptual modeling. Results: Our results showed that our DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. In addition, the evaluation of the models developed in this paper by using the quality framework for conceptual modeling showed that the models were of high quality. Conclusions: We have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models. However, given some potential drawbacks with respect to understandability and implementability, we primarily propose the use of DEMO within OSSD process modeling as an analysis tool that should be complemented with other techniques and models for communication and reenactment purposes.

The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

Moreover, there is no need to acquire skills in geographical information system (GIS) or programming languages for image analysis. Three use cases illustrated the software's functionality. The first involved monitoring the growth of sugar beet varieties in an experimental field using an unmanned aerial vehicle (UAV), where differences among varieties were detected through estimates of crop height, coverage, and volume index. Second, mixed varieties of potato crops were estimated using a UAV and varietal differences were observed from the estimated phenotypic traits. A strong correlation was observed between the manually measured crop height and UAV-estimated crop height. Finally, using a multicamera array attached to a tractor, the height, coverage, and volume index of the 3 potato varieties were precisely estimated. PREPs software is poised to be a useful tool that allows anyone without prior knowledge of programming to extract crop traits for phenotyping.","2024-08-09","2025-04-25 15:29:22","2025-04-25 15:29:22","","","","","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In a recent series of papers (DE MENEZES M. A. and BARABASI A.-L., Phys. Rev. Lett., 92 ( 2004) 28701; 93 ( 2004) 68701; YOOK S. H. and de MENEZES M. A., Europhys. Lett., 72 ( 2005) 541), de Menezes and co-workers have shown how to separate internal dynamics from external fluctuations by capturing the simultaneous activity of many system's components. In spite of software development being a planned activity, the analysis of fluctuations reveals how external driving forces can be only observed at weekly and higher time scales. Hourly and higher change frequencies mostly relate to internal maintenance activities. There is a crossover from endogenous to exogenous activity depending on the average number of. le changes. This new evidence suggests that software development is a non-homogeneous design activity where stronger efforts focus in a few project files. The crossover can be explained with a Langevin equation associated to the cascading process, where changes to any. le trigger additional changes to its neighbours in the software network. In addition, analysis of fluctuations enables us to detect whether a software system can be decomposed into several subsystems with different development dynamics.

Selected case example","RECHTSMEDIZIN","","0937-9819","10.1007/s00194-015-0067-9","","The identification of an unknown deceased person is an important task in forensic anthropology. There are various methods for identification, such as fingerprinting, odontostomatology and genetic fingerprinting, which presuppose the existence of reference material of the missing person; however, if there is no evidence of a person's identity the only possibility is often the use of forensic facial soft tissue reconstruction. This method is based on the high recognition level of a human face on the basis of bony structures of the skull and its anatomical features. The aim of this study was the design and application of a novel process for a computer-aided 3D facial soft tissue reconstruction on the basis of digital photographs of a skull. The facial soft tissue reconstruction was carried out on a selected forensic case and based on open source software. A complete facial soft tissue reconstruction of the deceased person was created based on 76 photographs of the skull taken with a Nikon D7100 SLR digital camera. The results show that for actual comparison images similar reconstruction results can be achieved. In addition, a model library for facial features was created. The presented workflow of a computer-aided 3D facial soft tissue reconstruction based on open source software is a cost-effective and flexible alternative to conventional reconstruction methods. It could be demonstrated that comparable reconstruction results can be achieved. Whether the reconstruction result actually leads to the recognition of the person depends on many other factors.","2016-04","2025-04-25 15:29:22","2025-04-25 15:29:22","","83-89","","2","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Yet, newcomers face a steep learning curve during OSS onboarding in which they must overcome a multitude of technical, social, and knowledge barriers. To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., “good first issues”), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.","2023","2025-04-25 15:29:23","2025-04-25 15:29:23","","324-336","","","","","","","International Conference on Software Engineering-Software Engineering Education and Training","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc","","","","","","","","","ISSN: 2832-756X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To maximize the potential of pCT it is necessary to develop advanced reconstruction algorithms that can accurately recover relative proton stopping power maps. This study aims to integrate pCT into STIR (Software for Tomographic Image Reconstruction), a popular Multi-Platform Object-Oriented framework for reconstruction in tomographic imaging to benefit from its software infrastructure. Open source STIR library is currently suitable for reconstructing and manipulating data from Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT), which are based on cylindrical scanner geometries. Although pCT has a non-cylindrical geometry, STIR provides the framework for single event detection and modelling of the proton interactions. This initial implementation includes classes and functions with new features such as general proton scanner geometry, binning of list mode proton data into sinograms and uses analytical reconstruction algorithms already available in STIR. The structure of the new implemented features is discussed. Future work will include additional components to establish STIR as a potential toolkit for pCT image reconstruction.","2019","2025-04-25 15:29:23","2025-04-25 15:29:23","","","","","","","","","IEEE Nuclear Science Symposium and Medical Imaging Conference","","","","IEEE","","","","","","","","","ISSN: 1095-7863","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

GNSS is a high-accuracy technique that is widely used today for monitoring and detecting deformations in the earth's crust and engineering structures. However, difficulties are encountered in the evaluation of measurements due to the intensive use of statistics in deformation analysis and the high numerical calculation load. Considering the possible consequences of deformations in the earth's crust and engineering structures, strategies and evaluation software are needed to determine them quickly. In this study, an open-source software that can be used in the analysis of deformation surveys carried out in campaigns with the static GNSS technique were developed by using R programming language since open-source deformation analysis software is missing in the field of deformation analysis. The method chosen for the determination of deformations is presented. The general features of the developed software are introduced, and a case study was carried out to test the computational performance of the software and to investigate which parameters are effective in determining the amount of deformation in GNSS networks correctly. As a result of the study, it was seen that ambiguity resolution rates and ionospheric activity affect the accuracy of the deformations determined in GNSS networks.","2022-09","2025-04-25 15:29:23","2025-04-25 15:29:23","","2051-2062","","3","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, frequent personnel turnover and lack of organizational management makes it difficult to capture the actual development effort. Various OSS maintenance effort estimation approaches have been developed to provide a way to understand and estimate development effort. The goal of this study is to identify the current state of art of the existing maintenance effort estimation approaches for OSS. We performed a systematic literature review on the relevant studies published in the period between 2000-2015 by both automatic and manual searches from different sources. We derived a set of keywords from the research questions and established selection criteria to carefully choose the papers to evaluate. 29 out of 3,312 papers were selected based on a well designed selection process. Our results show that the commonly used OSS maintenance effort estimation methods are actual effort estimation and maintenance activity time prediction; the most commonly used metrics and factors for actual effort estimation are source code measurements and people related metrics; the most commonly mentioned activity for maintenance activity time prediction is bug fixing. Accuracy measures and cross validation is used for validating the estimation models. Based on the above findings, we identified the issues in evaluation methods for actual maintenance effort estimations and the needs for quantitative OSS maintenance effort inference from size-related metrics. Meanwhile, we highlighted individual contribution and performance measurement as a novel and promising research area.","2016","2025-04-25 15:29:23","2025-04-25 15:29:23","","32-43","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn; NC State Univ","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Voxelized anatomical models are used in numerous applications including the computation of specific absorption rates associated with cell phone transmission energies, radiation therapy, and electromagnetic dosimetry simulation. Other applications range from the study of ergonomics to the design of clothing. Typically, the anatomical pose of a voxelized model is limited by the imaging device used to acquire the source anatomical data; however, absorption of emitted energies and the fit of clothes will change based on anatomic pose. Bender provides an intuitive, workflow-based user-interface to an extensible framework for changing the pose of anatomic models. Bender is implemented as a customized version of 3D Slicer, an image analysis and visualization framework that is widely used in the medical computing research community. The currently available repositioning methods in Bender are based on computer-graphics techniques for rigging, skinning, and resampling voxelized anatomical models.

Survivability, critical for maintaining project quality and trustworthiness, is closely linked to issue activity, as unresolved issues reflect a decline in maintenance capacity and problem-solving ability. Thus, analyzing issue retention rates provides valuable insights into a project's health. This study evaluates OSS survivability by identifying the features that influence issue activity and analyzing their relationships with survivability. Kaplan-Meier survival analysis is employed to quantify issue activity and visualize trends in unresolved issue rates, providing a measure of project maintenance dynamics. A random forest model is used to examine the relationships between project features-such as popularity metrics, community engagement, code complexity, and project age-and issue retention rates. The results show that stars significantly reduce issue retention rates, with rates dropping from 0.62 to 0.52 as stars increase to 4000, while larger codebases, higher cyclomatic complexity, and older project age are associated with unresolved issue rates, rising by up to 15%. Forks also have a nonlinear impact, initially stabilizing retention rates but increasing unresolved issues as contributions became unmanageable. By identifying these critical factors and quantifying their impacts, this research offers actionable insights for OSS project managers to enhance project survivability and address key maintenance challenges, ensuring sustainable long-term success.","2025-01","2025-04-25 15:29:23","2025-04-25 15:29:23","","","","2","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

CoRain is a free and open source software written in R language that could greatly help analyzing inhomogeneity caused by rainfall measuring instruments. CoRain compares two parallel rain series (with an overlapping period) and tries to highlight overestimations and underestimations due to rain gauges in a specific condition, so that the user can consider it for future analysis. CoRain offers many information on the two analyzed series, starting with cleaning input data, comparing them and classifying rainy days by severity. CoRain is a cross-platform software, easily adaptable to different needs, that takes in input a single text file with daily information of the two rain series and outputs tables (in CSV format) and plots (as PNG images) that help in the interpretation of the data. Use of the program is very simple: the execution can be either interactive or non-interactive.

We use SME to combine two well-known modelling methods, namely goal-oriented models (using i*) and business process models (using BPMN), with a pre-existing catalogue of goal-oriented OSS adoption strategy models. First, we define a repository of reusable method chunks, including the guidelines to apply them.

Assessing and monitoring the dynamics of phenology is relevant to support several decisions in order to improve the efficiency of several farming practices. An open source application QPhenoMetrics - implemented in QGIS software that estimates vegetation phenology metrics is presented, using Earth Observation Systems (EOS) based time-series of Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) as proxies for phenology. QPhenoMetrics is characterized by freely-usable and updatable code, acceptance of satellite images or text formats, time-series analysis toolbox allowing the selection of region of interest with statistical quality assessment for Vegetation Indices (VI), and estimation of ensemble metrics. The application is structured in three components: (i) input data; (ii) pre-processing of the VI time-series and several fitting methods and (iii) computation of the phenological metrics. QPhenoMetrics produces a plot with the VI time-series and corresponding phenology metrics, and a spreadsheet is created with a list of NDVI or EVI values estimated using the selected fitting method. To evaluate the application, two main Portuguese crops, vineyards and maize, and MOD13 data from MODIS sensor during 2011-2012 were considered. QPhenoMetrics was validated with vineyard phenology observations (2007-2011). A comparative analysis with software products TimeSat and Spirits was also performed. It was concluded that QPhenoMetrics can be very useful for common users to extract phenology information for 16 daily MODIS data in HDF format, text files with NDVI/EVI data and ASCII files, through a simple and intuitive graphic interface. Furthermore, the user can evaluate the quality assessment of VI of the images used.

One of the common practices during software development is the reuse of code. It can be achieved by utilizing libraries, frameworks, and other reusable components. Practically, when a fault is detected in replicated code, developers must check for similar faults in other copies, as there is a dependency between faults. To prevent recurrence of observed failures, developers must remove the corresponding leading fault and any related dependent faults. Many software reliability growth models (SRGMs) have been proposed and studied in the past, but most SRGMs assume that developers usually detect only one fault causing a failure. In actuality, it is necessary to consider the possibility of detecting multiple faults that may share similarities or dependencies. Additionally, some SRGMs rely on specific assumptions that may not always be valid, such as perfect debugging and/or immediate debugging. In this study, the modified diffusion models are proposed to handle these unrealistic situations, and are expected to better capture the dynamics of open source software (OSS) development. Experiments using real OSS data show that the proposed models can accurately describe the fault correction process of OSS. Finally, an optimal software release policy is proposed and studied. This policy takes into account some factors, including the remaining number of faults in the software, the expenses associated with identifying and rectifying those faults, and the level of market demand for the software. By considering these factors, developers can determine the optimal time to release the software to the market.","2023","2025-04-25 15:29:24","2025-04-25 15:29:24","","51631-51646","","","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the hope of facilitating this exploration and promoting the reproducibility of geophysical simulations and inversions, we have developed the open-source software package SimPEG. The software has been designed to be modular and extensible, with the goal of allowing researchers to interrogate all of the components and to facilitate the exploration of new inversion strategies. We present an overview of the software in its application to airborne electromagnetics and demonstrate its use for visualising fields and fluxes in a forward simulation, as well as its flexibility in formulating and solving the inverse problem. We invert a line of airborne time-domain electromagnetic data over a conductive vertical plate using a 1D voxel inversion, a 2D voxel inversion and a parametric inversion, where all of the forward modelling is done on a 3D grid.

Over the past years, several vulnerabilities have been found in popular open-source libraries like OpenSSL and FFmpeg. Mobile applications that include such libraries inherit these flaws, which make them vulnerable. Fortunately, the open-source community is responsive and patches are made available within days. However, mobile application developers are often left unaware of these flaws. The App Security Improvement Program (ASIP) is a commendable effort by Google to notify application developers of these flaws, but recent work has shown that many developers do not act on this information. Our work addresses vulnerable mobile applications through automatic binary patching from source patches provided by the OSS maintainers and without involving the developers. We propose novel techniques to overcome difficult challenges like patching feasibility analysis, source-code-to-binary-code matching, and in-memory patching. Our technique uses a novel variability-aware approach, which we implement as OSSPATCHER. We evaluated OSSPATCHER with 39 OSS and a collection of 1,000 Android applications using their vulnerable versions. OSSPATCHER generated 675 function-level patches that fixed the affected mobile applications without breaking their binary code. Further, we evaluated 10 vulnerabilities in popular apps such as Chrome with public exploits, which OSSPATCHER was able to mitigate and thwart their exploitation.","2019","2025-04-25 15:29:24","2025-04-25 15:29:24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is an open-source tool distributed under LGPL license, written in Java and based on the Chemistry Development Kit. Ambit-GCM provides an environment for creating models of molecular properties using additive schemes of zero, first or second orders. Ambit-GCM supports a set of local atomic attributes used for dynamic configuration of desired atom descriptions, which are applied to define fragments of different sizes. All defined groups are exhaustively generated for each molecule from a training set of compounds and combined to form the basic set of GCM fragments. Additionally, Ambit-GCM users can define correction factors via custom SMARTS notations or add externally calculated molecular descriptors. A molecular property model is obtained as a sum over all found groups by multiplying each group or correction factor frequency to its corresponding contribution. Multiple linear regression analysis (MLRA) is used for group contributions calculation. Ambit-GCM performs full statistical characterization of the obtained MLRA models via various validation techniques: external tests validation, cross validation, y-scrambling, etc. The software can be optionally used only for molecule fragmentation combined with an external statistical modelling package for further processing. Ambit-GCM example usage and test cases are given.","2019-08","2025-04-25 15:29:25","2025-04-25 15:29:25","","","","8-9, SI","38","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Static metrics for defect density prediction require extraction of abstract information from the code. Repository metrics, on the other hand, are easy to extract from the repository data sets. In this paper, an analysis has been performed over repository metrics of open source software. Further, defect density is being predicted using these metrics individually and jointly.

Making decisions about quality and adoption involves analysing code, documentation, online discussions, and issue trackers. There is too much information to process manually and it is common that uninformed decisions have to be made with detrimental effects. CROSSMINER aims to remedy this by automatically extracting the required knowledge and injecting it into the developers' Integrated Development Environments (IDE), at the time they need it to make design decisions. This allows them to reduce their effort in knowledge acquisition and to increase the quality of their code. CROSSMINER uniquely combines advanced software project analyses with online IDE monitoring.

The positive economical results of the project made software reuse a common practice at Orbotech. Further experimentation of reusing Open Source Software (OSS) demonstrated the high potential of that approach, when carefully integrated with the standard organizational development process. The conclusions from Orbotech experience are that when carefully planned and implemented, software reuse provides the anticipated benefits of cost reduction, improved quality and shorter Time-to-Market. The reuse of OSS may provide even higher benefits than conventional software reuse. Nevertheless, as in many cases before, implementation of software reuse requires management support and commitment, as well as acceptance by the developers themselves. As such, software reuse implementation proves to be a complex task that needs to be tailored specifically to the implementing organization.","2005","2025-04-25 15:29:25","2025-04-25 15:29:25","","110-117","","","","","","","","","","","IEEE Comp Soc, Israeli Chapter; Israeli Users Assoc Adv Technologies Elect Ind","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Second, most pipelines are implemented in special hardware, resulting in limited flexibility of implemented processing steps on such platforms. With SUPRA, we propose an open-source pipeline for fully software-defined ultrasound processing for real-time applications to alleviate these problems. Covering all steps from beamforming to output of B-mode images, SUPRA can help improve the reproducibility of results and make modifications to the image acquisition mode accessible to the research community. We evaluate the pipeline qualitatively, quantitatively, and regarding its run time. The pipeline shows image quality comparable to a clinical system and backed by point spread function measurements a comparable resolution. Including all processing stages of a usual ultrasound pipeline, the run-time analysis shows that it can be executed in 2D and 3D on consumer GPUs in real time. Our software ultrasound pipeline opens up the research in image acquisition. Given access to ultrasound data from early stages (raw channel data, radiofrequency data), it simplifies the development in imaging. Furthermore, it tackles the reproducibility of research results, as code can be shared easily and even be executed without dedicated ultrasound hardware.","2018-06","2025-04-25 15:29:25","2025-04-25 15:29:25","","759-767","","6, SI","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These commands are in an intuitive format which provides great flexibility and allows quick and easy adaptation to various measurement needs. For each of these commands, the iC-framework calls a corresponding Java method that addresses the specified instrument to perform the desired task.

Because students are accustomed to gathering information using commercial search engines, they can overlook high-quality library resources. To connect with student researchers when they need library resources, many libraries have built online research guides tied to specific subjects and courses. These guides can address specific assignments where research is required, and course instructors can point students to the guides to assist them in completing their research assignments successfully. In 2006, Oregon State University (OSU) Libraries developed an open source software product called Library a la Carte that librarians can use to construct research guides easily and quickly. The code was made available to other libraries, and a number of institutions have adopted the tool. A successful user community has grown up around Library a la Carte, but development up to this point has been the sole responsibility of OSU Libraries. We are now embarking on building a robust developer community, to contribute code, to build additional features and to take Library a la Carte into the future. As part of our plan to move forward, we are testing a hosted (cloud-based) version of the software. This paper introduces Library a la Carte, presents what was learned from the test and discusses moving forward with building a developer community.

The open source characteristics of the platform allow to consider this an initiative “ad includendum” (looking for inclusion of other entities), as further research institutions, private developers etc. may contribute to the platform development. Through creating a common environment among water research/professionals, policy makers and implementers, FREEWAT main impact will be on enhancing science- and participatory approach and evidence-based decision making in water resource management, hence producing relevant and appropriate outcomes for policy implementation. The Consortium is constituted by partners from various water sectors from 10 EU countries, plus Turkey and Ukraine. Synergies with the UNESCO HOPE initiative on free and open source software in water management greatly boost the value of the project. Large stakeholders involvement is thought to guarantee results dissemination and exploitation.","2015-04","2025-04-25 15:29:26","2025-04-25 15:29:26","","252-255","","","35","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Results from a meta-analysis of all clinical trials (up to 2011) indicated a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. Our objective of this study is to build a virtual breast phantom lab in the public domain that can be used for rigorous imaging testing of this kind. Main thrust of this work is to streamline biomedical ultrasound simulations in conjunction with anatomically complex (software) phantoms by leveraging existing open source software packages including K-wave or Field II (acoustic simulation), VTK (data visualization and processing), FEBio (biomechanical deformation) and Tetgen (mesh generation). The integration of these four open source packages was based on a simple message-passing scheme to facilitate its use among imaging scientists. In this study, we demonstrated that a complex and heterogeneous (virtual) breast phantom can be derived from medical imaging data, i.e. publically available Visible Human Project data through US National Institutes of Health. Three volumes of interest were selected from the proposed virtual breast phantom to perform acoustic simulations using a virtual linear array transducer (6MHz and 80% bandwidth). Our initial results showed that simulated B-mode images accurately represented the underlying complex but known medium. In order to demonstrate applications in elastography, the virtual breast phantom was also deformed using finite element simulations. The resultant simulated strain image depicted complex patterns that were normally seen in clinical data. In conclusion, the proposed virtual software infrastructure can perform sophisticated ultrasound simulations in conjunction with complex and heterogeneous media. It is our intent that, in the future, the proposed virtual software infrastructure will be available to the research community for use in creation complex imaging benchmark tests for algorithm testing and validation. Furthermore, the proposed virtual platform can also be tailored to meet specific research needs by potential users themselves in an open science fashion. Collectively, these activities will accelerate development of ultrasound imaging including elastography.","2014","2025-04-25 15:29:26","2025-04-25 15:29:26","","1841-1844","","","","","","","IEEE International Ultrasonics Symposium","","","","IEEE","","","","","","","","","ISSN: 1948-5719","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While this model lowers the barrier to entry for OSS developers by synthesizing, automating and optimizing the contribution process, coordination among an increasing number of contributors remains as a challenge due to the asynchronous and self-organized nature of distributed development. In particular, duplicate contributions, where multiple different contributors unintentionally submit duplicate pull requests to achieve the same goal, are an elusive problem that may waste effort in automated testing, code review and software maintenance. While the issue of duplicate pull requests has been highlighted, to what extent duplicate pull requests affect the development in OSS communities has not been well investigated. In this paper, we conduct a mixed-approach study to bridge this gap. Based on a comprehensive dataset constructed from 26 popular GitHub projects, we obtain the following findings: (a) Duplicate pull requests result in redundant human and computing resources, exerting a significant impact on the contribution and evaluation process. (b) Contributors' inappropriate working patterns and the drawbacks of their collaborating environment might result in duplicate pull requests. (c) Compared to non-duplicate pull requests, duplicate pull requests have significantly different features, e.g., being submitted by inexperienced contributors, being fixing bugs, touching cold files, and solving tracked issues. (d) Integrators choosing between duplicate pull requests prefer to accept those with early submission time, accurate and high-quality implementation, broad coverage, test code, high maturity, deep discussion, and active response. Finally, actionable suggestions and implications are proposed for OSS practitioners.","2022-04-01","2025-04-25 15:29:26","2025-04-25 15:29:26","","1309-1335","","4","48","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is very important for open source projects to be impactful, i.e., to attract attentions from the open source development community, so as to gain support on development, testing as well as maintenance from the community. However, the question of what factors affect open source project impact, remains largely open. Given the numerous confounding factors and the complex correlations among the factors, it is a challenge to answer the question. In this study, we gather a large dataset from GitHub and provide empirical insights on this question base on a data-driven approach.

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project's capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of subtopics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project's overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.","2022","2025-04-25 15:29:26","2025-04-25 15:29:26","","","","","","","","","","","","","Univ Rey Juan Carlos; Vicerrectorado Extens Univ; GsyC/LibreSoft Res Grp; Programamos.es; John Ernest Fdn; ACM In Cooperat; SIGSOFT; SIGWEB","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is essential to differentiate between the unethical act of plagiarism and the legitimate use of open-source resources. Existing copyright protection measures, such as license design, inadequately address copyright ownership and protection issues. Furthermore, they fail to detect plagiarism methods for open-source hardware projects, such as circuit location modification. To address these challenges, this paper proposes a blockchain-based copyright management scheme, which introduces a general originality detection model based on community detection, extracting adjustable granularity digests from code and design files. These digests are stored on a peer-to-peer blockchain, enabling nodes to verify the originality via smart contracts. Additionally, the scheme improves the storage structure, protecting the rights of authors and contributors. Experimental results demonstrate the effectiveness and runtime efficiency of the proposed model in extracting digests for blockchain storage while maintaining verification accuracy. The scheme offers enhanced generality, practical performance, and suitability for distributed development and maintenance, with considerable implications for evidence gathering, fostering innovation and integrity.","2025-06","2025-04-25 15:29:26","2025-04-25 15:29:26","","1157-1173","","3","30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the increased complexity of computer systems and a variety of applications, it is hard for software developers to master the expertise required to deal with the variety of security concepts, methods, and technologies that are required in software projects. Although a large number of security learning materials are widely available in books, open literature or on the Internet, they are difficult for learners to understand the rationale of security topics and correlate the concepts with real software scenarios. We argue that the traditional approach, which usually organizes knowledge content topically, with security-centric, is not suitable to motivate learners and stimulate learners' interest. To tackle this learning issue, our research is focused on forging a contextualized learning environment for software security where learners can explore security knowledge and relate it to the context that they are familiar with. This learning system is developed base on our proposed context-based learning approach and based on ontological technologies. In this paper, we present our evaluation study in the open source software (OSS) development environment. Our results demonstrate that contextualized learning can help OSS developers identify their necessary security information, improve learning efficiency and make security knowledge more meaningful for their software development tasks","2019","2025-04-25 15:29:26","2025-04-25 15:29:26","","","","","","","","","","","","","SBA Res; Univ Kent","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted an abductive, computationally intensive study of eight OSS projects, using relational event modeling to analyze 1,169,489 actions covering 93 major software releases. The process of entrainment that we identify involves three task allocation mechanisms: (1) developer -issue inertia, (2) developer contribution frequency, and (3) issue popularity. Our analysis demonstrates that these mechanisms and the phases of the release cycle entrain each other. Before a major release, developers engage in a concentrated mobilization phase, whereby they democratize development activity and increasingly allocate community contributions to the set of issues related to the release. After a major release, the extended cleanup phase garners a greater share of development work from recently highly active developers and dilutes the activity of these developers across a wider range of issues. Our theorizing suggests that major releases constitute important events around which OSS communities self -organize and we characterize how this occurs. Our research contributes to theorizing on organizing in OSS communities by explaining how selforganizing task allocation interacts with release cycles through the mechanism of entrainment. We also contribute to the literature on entrainment by showing how it may unfold in the context of online peer production communities such as OSS.","2024-03","2025-04-25 15:29:26","2025-04-25 15:29:26","","67-94","","1","48","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In both academic and industry data analytics, open-source software (OSS) has gained massive popularity. Collaborative source code allows students to interact with researchers, code developers, and users from a variety of disciplines. Based on the authors' experiences as graduate students and coding instructors, this paper provides a unique overview of the obstacles that graduate students face in obtaining the knowledge and skills required to complete their research and in transitioning from an OSS user to a contributor: psychological, practical, and cultural barriers and challenges specific to graduate students including cognitive load in graduate school, the importance of a knowledgeable mentor, seeking help from both the online and local communities, and the ongoing campaign to recognize software as research output in career and degree progression. Specific and practical steps are recommended to provide a foundation for graduate students, supervisors, administrators, and members of the OSS community to help overcome these obstacles. In conclusion, the objective of these recommendations is to describe a possible framework that individuals from across the scientific community can adapt to their needs and facilitate a sustainable feedback loop between graduate students and OSS.","2020-05-07","2025-04-25 15:29:27","2025-04-25 15:29:27","","289-303","","","5","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, migration to open source software has its own risks, such as training of employee, lack of compatibility, and support. Reviewing numerous papers found in the literature, this study aims to collect a complete list of risks that may influence the open source migration process as much as possible. It also provides a new categorization of the risks by which each risk is classified based on its type (organizational, technical, and environmental), and its time of occurrence (before, during, and after migration). Moreover, this paper proposes a number of conceivable measures to mitigate each risk; some of them are proposed for the first time in this area of research. The results of this study can help organizations' decision makers to make better decisions in the open source migration process.","2017","2025-04-25 15:29:27","2025-04-25 15:29:27","","134-139","","","","","","","","","","","Int Assoc Comp Sci & Informat Technol","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many projects leverage the contribution of outsiders, and the sustainability of the project relies on retaining some of these newcomers. This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review; (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects; (iii) 24 responses to a questionnaire sent to 9 OSS projects; and (iv) semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practitioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteristics, reception issues, orientation, technical hurdles, and documentation problems. We could observe recurrent barriers evidenced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-25 15:29:27","2025-04-25 15:29:27","","51+","","","","","","","","","","","Univ Fed Alagoas; Ufal; CAPES; Conselho Nacl Desenvolvimento Cientifico & Tecnologico; Ines; Google; Inst Fed Alagoas; Aloo Telecom; Alagoas Governo Estado, Secretaria Estado Turismo; Maceio Convent & Visitors Bur; Soc Brasileira Computacao; Josi Mendes Consultoria & Eventos; Transamerica Turismo; IEEE Comp Soc","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there is a lack of studies in literature that shed light into the evaluation of OSS by organizations. In this article, a method to evaluate reliability and maintainability of OSS by using both code-based and community-based aspects is proposed through the synthesis of existing studies in literature. To perform code-based evaluation, some internal attributes of the most recent quality model, ISO/IEC 25010, are selected and object-oriented C&K metrics are employed in an attempt to measure these attributes. To perform community-based evaluation, metrics derived from historical data such as e-mailing lists, problem reports, frequently asked questions, and etc. are utilized to identify and satisfy information needs as conformant to ISO/IEC 15939 standard for software measurement process. The two-dimensional method was used in selection of the Java build tools written in Java, and the results obtained by applying the proposed method and the results obtained by using OSMM and OpenBRR which are common methods in the literature were compared. According to the evaluation and comparison results, the results obtained with the existing models confirm each other and the results obtained with the proposed method.","2019","2025-04-25 15:29:27","2025-04-25 15:29:27","","1807-1829","","4","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Specifically, we analyze the change history of these systems at commit level to investigate: (i) whether developers perform refactoring operations and, if so, which are more diffused and (ii) when refactoring operations are applied, and (iii) which are the main developer-oriented factors leading to refactoring. Based on our results, future research can focus on enabling automatic support for less frequent refactorings and on recommending refactorings based on the developer's workload, project's maturity and developer's commitment to the project.

Genomic selection (GS) predicts genomic breeding values (GEBV) using dense genetic markers. Single-stage models predict GEBVs from phenotypic observations in one step, fully accounting for the entire variance-covariance structure among genotypes, but face computational challenges. Two-stage models, preferred for their simplicity and efficiency, first calculate adjusted genotypic means accounting for spatial variation within each environment, then use these means to predict GEBVs. However, unweighted (UNW) two-stage models assume independent errors among adjusted means, neglecting correlations among estimation errors. Here, we show that fully-efficient two-stage models perform similarly to UNW models for randomized complete block designs but substantially better for augmented designs. Our simulation studies demonstrate the impact of the fully-efficient methodology on prediction accuracy across different implementations and scenarios. Incorporating non-additive effects and augmented designs significantly improved accuracy, emphasizing the synergy between design and model strategy. Consistent performance requires the estimation error covariance to be incorporated into a random effect (Full_R model) rather than into the residuals. Our results suggest that the fully-efficient methodology, particularly the Full_R model, should be more prevalent, especially as GS increases the appeal of sparse designs. We also provide a comprehensive theoretical background and open-source R code, enhancing understanding and facilitating broader adoption of fully-efficient two-stage models in GS. Here, we offer insights into the practical applications of fully-efficient models and their potential to increase genetic gain, demonstrating a 13.80%\textbackslashdocumentclass[12pt]{minimal} \textbackslashusepackage{amsmath} \textbackslashusepackage{wasysym} \textbackslashusepackage{amsfonts} \textbackslashusepackage{amssymb} \textbackslashusepackage{amsbsy} \textbackslashusepackage{mathrsfs} \textbackslashusepackage{upgreek} \textbackslashsetlength{\textbackslashoddsidemargin}{-69pt} \textbackslashbegin{document}\13.80\textbackslash%\textbac kslashend{document} improvement after five selection cycles when moving from UNW to Full_R models.","2025-02-04","2025-04-25 15:29:27","2025-04-25 15:29:27","","","","1","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper constructs the developer collaboration network of the Cloud Foundry OSS community by coding-collaboration relationships, and then analyses the structure and evolution of the constructed network. The results show that a modular pattern centering on a few developers gradually emerges in the developer collaboration network after an evolutionary process of three stages. Core developers have completed a large proportion of the development work and played a coordinating role in development activities, while the periphery developers submit code to specific sub-projects according to their technical background, which complements the core developers' work. Furthermore, the modules of the developer collaboration network are intrinsically related to the sub-projects and continuously contribute code for the corresponding subprojects during the evolutionary process. These results may deepen our understandings of the collaborative pattern of OSS communities, and also have some reference value for the studies of open collaborative innovation in large scale crowds.","2019","2025-04-25 15:29:27","2025-04-25 15:29:27","","87-105","","","1103","","","","Communications in Computer and Information Science","","","","Int Soc Knowledge & Syst Sci","","","","","","","","","ISSN: 1865-0929","","","","","","Chen, J; Huynh, V; Nguyen, GN; Tang, X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects.

Its validation was performed by using smartphone cameras to record video and open-source portable software tools (OpenCap and Pose2Sim). The results show that the sensor is capable of providing the joint angle with appreciable accuracy, with a maximum error of about 4 degrees, falling within the mean error of the validation tools, and a larger error only for angles at the extremes of the analyzed range of motion.

In such platforms, developers have to collaborate and deal with issues of collaboration in open-source software development. Although collaboration is challenging, collaborative development produces better software systems than any developer could produce alone. Several approaches have investigated collaboration challenges, for instance, by proposing or evaluating models and tools to support collaborative work. Despite the undeniable importance of the existing efforts in this direction, there are few works on collaboration from perspectives of developers. In this work, we aim to investigate the perceptions of open-source software developers on collaborations, such as motivations, techniques, and tools to support global, productive, and collaborative development. Following an ad hoc literature review, an exploratory interview study with 12 open-source software developers from GitHub, our novel approach for this problem also relies on an extensive survey with 121 developers to confirm or refute the interview results. We found different collaborative contributions, such as managing change requests. Besides, we observed that most collaborators prefer to collaborate with the core team instead of their peers. We also found that most collaboration happens in software development (60%) and maintenance (47%) tasks. Furthermore, despite personal preferences to work independently, developers still consider collaborating with others in specific task categories, for instance, software development. Finally, developers also expressed the importance of the social coding platforms, such as GitHub, to support maintainers, and contributors in making decisions and developing tasks of the projects. Therefore, these findings may help project leaders optimize the collaborations among developers and reduce entry barriers. Moreover, these findings may support the project collaborators in understanding the collaboration process and engaging others in the project.","2023-05","2025-04-25 15:29:27","2025-04-25 15:29:27","","","","5, SI","35","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The “private investment” model assumes returns to the innovator result from private goods and efficient regimes of intellectual property protection. The “collective action” model assumes that under conditions of market failure, innovators collaborate in order to produce a public good. The phenomenon of open source software development shows that users program to solve their own as well as shared technical problems, and freely reveal their innovations without appropriating private returns from selling the software. In this paper, we propose that open source software development is an exemplar of a compound “private-collective” model of innovation that contains elements of both the private investment and the collective action models and can offer society the “best of both worlds” under many conditions. We describe a new set of research questions this model raises for scholars in organization science. We offer some details regarding the types of data available for open source projects in order to ease access for researchers who are unfamiliar with these, and also offer some advice on conducting empirical studies on open source software development processes.","2003-04","2025-04-25 15:29:27","2025-04-25 15:29:27","","209-223","","2","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Different characteristics of bugs, such as severity, priority, and time to fix, provide a clear picture of an ITS. Nevertheless, such information may be misleading. For example, the exact time and the effort spent on a bug might be significantly different from the actual reporting time and the fixing time. Similarly, these values may be subjective, e.g., severity and priority values are assigned based on the intuition of a user or a developer rather than a structured and well-defined procedure. Hence, we explore the evolution of the bug dependency graph together with priority and severity levels to explore the actual triage process. Inspired by the idea of the “Wayback Machine “for the World Wide Web, we aim to reconstruct the historical decisions made in the ITS. Therefore, any bug prioritization or bug triage algorithms/scenarios can be applied in the same environment using our proposed ITS Wayback Machine. More importantly, we track the evolutionary metrics in the ITS when a custom triage/prioritization strategy is employed. We test the efficiency of the proposed algorithm using data extracted from three open-source projects. Our empirical study sheds light on the overlooked evolutionary metrics - e.g., overdue bugs and developers' loads - which are facilitated via our proposed past-event re-generator.

Extracting and analyzing useful plant phenotypic traits from hyperspectral images represents a major bottleneck for plant science and breeding communities. This study aims to present a stand-alone easy-to-use software platform called HSI-PP to process and analyze hyperspectral images for high-throughput plant phenotyping. The HSI-PP software integrates pre-processing, feature extraction, and modeling functions. The application of HSI-PP is exemplified by investigating the response of different Arabidopsis thaliana genotypes to drought stress, and the impact of various imaging angles on predicting the canopy nitrogen content (CNC) of oilseed rape (Brassica napus L.). The results showed that HSI-PP can process 10 GB on an ordinary PC in time ranging from 30 to 73 min according to image size and the complexity of the pipeline. HSI-PP extracted multiple phenotyping traits (spectral, textural, and morphological) of Arabidopsis thaliana from a large image dataset (104 GB) within five hours. The fusion of these features achieved higher accuracy (94%) than only using spectral information (85%) as early as day 4 after drought stress treatment. For oilseed rape, about 384 GB image data was processed within eighteen hours, and it was found that the tilted imaging angle of 75 had the optimized PLSR fitting (0.83) to the ground truth. The results demonstrate that HSI-PP is a stand-alone, automated, and open-source hyperspectral image processing platform adapted to various applications in plant phenotyping without requiring professional programming skills to serve the plant research community.","2022-09","2025-04-25 15:29:28","2025-04-25 15:29:28","","","","","200","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Following a survey of 222 FOSS developers, we find conflict to have an overall negative effect on developer retention. Furthermore, different types of conflict have varying impact on outcomes. In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes.

However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 15:29:28","2025-04-25 15:29:28","","1439-1458","","3","44","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The lack of efficient tools to accurately model tissue structures and subsequently perform quantitative multiphysics modeling greatly impedes the clinical translation of these modalities. Aim: Although the mesh-based Monte Carlo (MMC) method expands our capabilities in simulating complex tissues using tetrahedral meshes, the generation of such domains often requires specialized meshing tools, such as Iso2Mesh. Creating a simplified and intuitive interface for tissue anatomical modeling and optical simulations is essential toward making these advanced modeling techniques broadly accessible to the user community. Approach: We responded to the above challenge by combining the powerful, open-source three-dimensional (3D) modeling software, Blender, with state-of-the-art 3D mesh generation and MC simulation tools, utilizing the interactive graphical user interface in Blender as the front-end to allow users to create complex tissue mesh models and subsequently launch MMC light simulations. Results: Here, we present a tutorial to our Python-based Blender add-on-BlenderPhotonics- to interface with Iso2Mesh and MMC, which allows users to create, configure and refine complex simulation domains and run hardware-accelerated 3D light simulations with only a few clicks. We provide a comprehensive introduction to this tool and walk readers through five examples, ranging from simple shapes to sophisticated realistic tissue models. Conclusions: BlenderPhotonics is user friendly and open source, and it leverages the vastly rich ecosystem of Blender. It wraps advanced modeling capabilities within an easy-to-use and interactive interface. The latest software can be downloaded at http://mcx.space/bp. (C) The Authors.

On this rationale, this study was carried out to explore the applicability of the concept of converging `Free and Open Source Software (FOSS)' to promote sustainable knowledge sharing amongst the agricultural communities in Sri Lanka. A multi-stage community consultative process with a set of designated officials (”Sponsors”) and a series of semi-structured questionnaire survey with a cross section of smallholder agriculture farmers (n=246), were carried out in the Batticaloa, Kurunegala and Puttalam districts to gather the baseline data. This was followed by a number of field experiments (”Campaigns”) with the farmers (n=340) from same geographical areas. The two FOSS, namely: (1) “FrontlineSMS” for `Text Messaging' and (2) “FreedomFone” for `Interactive Voice Responses', were applied to evaluate the effectiveness of knowledge sharing within the farming communities. It was found that FOSS intervention increases the `Text messaging' and `Voice Call' usage in day-to-day agricultural communication by 26 and 8 percent, respectively. The demographic factors like age and educational level of the farmers have a positive influence on the knowledge sharing process. And also the `Mobile Telephony' was the most extensive mode of communication within the communities. The outcome of analysis, as a whole, implies that, with a fitting mechanism in place, this approach can be promoted as a “drive for positive changes” in agriculture-based rural communities in developing countries like Sri Lanka, and those in South and East Asia with similar socioeconomic and cultural perspectives.","2017","2025-04-25 15:29:28","2025-04-25 15:29:28","","351-359","","2","111","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Among these new technologies is fiber photometry, a technique wherein an implanted fiber optic is used to record signals from genetically encoded fluorescent sensors in bulk tissue. Fiber photometry has been widely adapted due to its cost-effectiveness, ability to examine the activity of neurons with specific anatomical or genetic identities, and the ability to use these highly modular systems to record from one or more sensors or brain sites in both superficial and deep-brain structures. Despite these many benefits, one major hurdle for laboratories adopting this technique is the steep learning curve associated with the analysis of fiber photometry data. This has been further complicated by a lack of standardization in analysis pipelines. In the present communication, we present pMAT, a `photometry modular analysis tool' that allows users to accomplish common analysis routines through the use of a graphical user interface.

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities. (C) 2013 The Authors. Published by Elsevier Inc.

First, according to the snowball sampling data collection method and the grounded theory, the data is collected and processed. Second, by designing evaluation indicators and utility functions, the projection pursuit classification model of the natural ecosystem is evaluated and combined with a real-coded accelerated genetic algorithm, thereby designing the health measure model.

OSS projects depend mainly on volunteer developers, and attracting and retaining these volunteers are major concerns of the project stakeholders. To investigate the population structures of OSS development communities in detail and conduct software analytics to obtain actionable information, we apply a demographic approach. Demography is the scientific study of population and seeks to identify the levels and trends in the size and components of a population. This paper presents a case study, investigating the characteristics of the population structures of OSS projects on GitHub, and shows population projections generated with the well-known cohort component method. We found that there are four types of population structures in OSS development communities in terms of experiences and contributions. In addition, we projected the future population accurately using a cohort component population projection method. This method predicts a population of the next period using a survival rate calculated from past population. To the best of our knowledge, this is the first study that applied demography to the field of OSS research. Our approach addressing OSS-related problems based on demography will bring new insights, since studying population is novel in OSS research. Understanding current and future structures of OSS projects can help practitioners to monitor a project, gain awareness of what is happening, manage risks, and evaluate past decisions.","2016-05","2025-04-25 15:29:28","2025-04-25 15:29:28","","1304-1315","","5","E99D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process.

Based on a pragmatic framework, the prospects of integrating OSS in a traditional software engineering curriculum are outlined and concerns in realizing them are given. In doing so, the cases of the adoption of OSS process model, use of OSS as a Computer Aided Software Engineering (CASE) tool, OSS as a standalone sub-system, and open source code reuse are considered. We present some of the trade-offs that could help educators in decision making towards the use of the OSS environment in software engineering pedagogical contexts. The significance of openly accessible content in general and its relation to OSS in particular is briefly highlighted.","2007","2025-04-25 15:29:29","2025-04-25 15:29:29","","45-64","","","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm's practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems. (C) 2017 The Authors.

Such an incorporation of COTS tools into an overall open-source approach completely annihilates the actual open-source advantages and goals. In this tool paper, we demonstrate how we eliminated a COTS tool from the otherwise open-source-based generation and evolution workflow of the domain-specific modeling language East-Adl, used in the automotive industry to describe a variety of interdisciplinary aspects of vehicle systems. By switching to a pure open-source solution, East-Adl becomes easier to inspect, evolve, and develop a community around.

For example, contributors must protect authentication credentials for software repositories, code-signing keys, and their systems from malware. Previous incidents illustrated that open-source contributors struggle with protecting their development environment. In contrast to companies, open-source software projects cannot easily enforce security guidelines for development environments. Instead, contributors' security setups are likely heterogeneous regarding chosen technologies and strategies. To the best of our knowledge, we perform the first in-depth qualitative investigation of the security of open-source software contributors' individual security setups, their motivation, decision-making, and sentiments, and the potential impact on open-source software supply chain security. Therefore, we conduct 20 semi-structured interviews with a diverse set of experienced contributors to critical open-source software projects. Overall, we find that contributors have a generally high affinity for security. However, security practices are rarely discussed in the community or enforced by projects. Furthermore, we see a strong influence of social mechanisms, such as trust, respect, or politeness, further impeding the sharing of security knowledge and best practices. We conclude our work with a discussion of the impact of our findings on open-source software and supply chain security, and make recommendations for the open-source software community.","2024","2025-04-25 15:29:29","2025-04-25 15:29:29","","1065-1082","","","","","","","IEEE Symposium on Security and Privacy","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 1081-6011","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Variability in these systems not only occurs in functionality, but also in quality attributes (e. g., security, reliability, dependability). Furthermore, variability in functionality and variability in quality attributes affect each other. Recently, open source communities have adopted microblogging to document and share software engineering knowledge. Microblogging dissolves boundaries between developers and other stakeholders (e.g., end users). This facilitates the involvement of many different non-technical stakeholders in the software development process. In this paper, we investigate the feasibility and suitability of utilizing microblogs to identify and analyze dependability information about open source software systems. We use the example of the currently most popular microblogging infrastructure (Twitter) and a widely used open source content management system (Drupal). Our results indicate that even though open source communities frequently share information on Twitter, challenges exist for extracting and analyzing dependability information. Furthermore, a better understanding is needed to describe the relation between issues reported by user communities in microblogs, and issues and actions documented by developer communities in change logs and release information.","2013","2025-04-25 15:29:29","2025-04-25 15:29:29","","321-325","","","","","","","","","","","IEEE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although existing research recognizes the importance of trust, there is a lack of an effective and scalable computational method to measure trust in an OSS community. Consequently, OSS project members must rely on subjective inferences based on fragile and incomplete information for trust-related decision making. We propose an automated approach to assist a developer in identifying the trustworthiness of another developer. Our two-fold approach, first, computes direct trust between developer pairs who have interacted previously by analyzing their interactions via natural language processing. Second, we infer indirect trust between developers who have not interacted previously by constructing a community-wide developer network and propagating trust in the network. A large-scale evaluation of our approach on a GitHub dataset consisting of 24,315 developers shows that contributions from trusted developers are more likely to be accepted to a project compared to contributions from developers who are distrusted or lacking trust from project members. Further, we develop a pull request classifier that exploits trust metrics to effectively predict the likelihood of a pull request being accepted to a project, demonstrating the practical utility of our approach.","2019-12-30","2025-04-25 15:29:29","2025-04-25 15:29:29","","","","12","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because OSS development is community based, unlike commercial software, the lack of good documentation or the maintenance of manuals is one of the main problems of using OSS. Due to its rapid development, OSS manuals become easily obsolete. Moreover, the installation or the usage varies depending on the operating system. To solve the documentation problems, Murakami et al. proposed a method of automatically generating a web manual for installing an OSS by editing the log information recorded during the installation process. Unfortunately, the web manual generated by this system was not suitable for wide use in learning management systems. Therefore, this paper extends the system by Murakami et al. to one with the ability to deliver an automatically generated Web manual on an e-learning management system, modify the content of the manual, and skip unnecessary information in the learning process.

We address this gap, studying how existing OSS code is reused and serves as an input to further OSS development. Our findings are based on a survey with 686 responses from OSS developers. As the most interesting results, our multivariate analyses of developers' code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early-as the “credible promise” in OSS-leads to increased reuse. Finally, we identify developers' interest in tackling difficult technical challenges as detrimental to efficient reuse-based innovation.

We examine two kinds of problem/project-behaviors: Individuals can set up projects around the formulation of new problems or join existing projects and define and/or work on subproblems within an existing problem. The choice between these two behaviors is influenced by the mode of communication. A communication mode with little a priori structure is the best mode for communicating about new problems (i.e., formulating a problem); empirically, it is associated with project launching behaviors. In contrast, more structured communication fits subproblems better and is related to project joining behaviors. Our hypotheses derive support from data from the FOSS community.Managerial summary: We study how the way in which individuals communicate influence the project-behaviors they engage in. We find that relatively unstructured communication is associated with the setting up new projects, while communication that is structured around an artifact is associated with joining projects. Our findings hold implications for understanding how management may influence project behaviors and problem-solving: Firms that need to concentrate on more incremental problem-solving efforts (e.g., because a sufficient number of attractive problems have already been defined) should create environments in which interaction is undertaken mainly via artifacts. On the other hand, if firms seek to generate new problems (e.g., new strategic opportunities), they should create environments in which open-ended, verbal conversation is relatively more important than artifact-based communication.

The techniques for performing inspections have been well studied in industry; in OSS development, software peer reviews are not as well understood. To develop an empirical understanding of OSS peer review, we examine the review policies of 25 OSS projects and study the archival records of six large, mature, successful OSS projects. We extract a series of measures based on those used in traditional inspection experiments. We measure the frequency of review, the size of the contribution under review, the level of participation during review, the experience and expertise of the individuals involved in the review, the review interval, and the number of issues discussed during review. We create statistical models of the review efficiency, review interval, and effectiveness, the issues discussed during review, to determine which measures have the largest impact on review efficacy. We find that OSS peer reviews are conducted asynchronously by empowered experts who focus on changes that are in their area of expertise. Reviewers provide timely, regular feedback on small changes. The descriptive statistics clearly show that OSS review is drastically different from traditional inspection.","2014-08","2025-04-25 15:29:30","2025-04-25 15:29:30","","","","4, SI","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Examining what motivates participants in OSS projects and how to enhance the effects of motivations has received increased attention in recent years. This study is prompted by the significant but detail-lacking examination of differential effects of various types of extrinsic motivations on participants' task effort in OSS projects and their interaction effects with participants' psychological states. Drawing upon self-determination theory, we establish four types of extrinsic motivations in OSS communities (i.e., external, introjected, identified, and integrated motivation) and investigate how these types affect task effort differently. Also, integrating self-determination theory with affective event theory, we study how satisfaction of needs for competence, autonomy, and relatedness moderates the relationships between extrinsic motivations and task effort. The research model is largely supported by data from 250 participants in various OSS projects.

However, the form that data sharing took in genomics was a result of specific technological practices. Biologists developed and adopted technologies of the nascent World Wide Web and Free and Open Source Software (FOSS) communities for sharing biological information. These technologies supported decentralized, collaborative, and nonproprietary modes of production in biology. Such technologies were appealing not merely because they were expedient for genomic work but because they also offered a way of promoting a particular form of genomic practice. As the genome sequencing centers scaled up their sharing efforts, a small group of computer-savvy biologists used these tools to promote the interests of the public genome sequencing effort. The agreements at Bermuda should be understood as part of this attempt to foster a particular form of genomic work.","2015","2025-04-25 15:29:30","2025-04-25 15:29:30","","465-503","","4","50","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Later, during the analysis phase of the study, the researcher splits the recorded data trace into smaller sections, analyzes each section separately by finding a mean or fitting against a specified function, and uses the analysis results in the study. Here, we present the software that allows to analyze these data traces in a manner that ensures repeatability of the analysis and simplifies the application of FAIR (findability, accessibility, interoperability, and reusability) principles in such studies. At the same time, it simplifies the routine data analysis pipeline and gives access to a fast overview of the analysis results. For that, the software supports reading the raw data, processing the data as specified in the protocol, and storing all intermediate results in the laboratory database. The software can be extended by study- or hardware-specific modules to provide the required data import and analysis facilities. To simplify the development of the data entry web interfaces, that can be used to enter data describing the experiments, we released a web framework with an example implementation of such a site. The software is covered by open-source license and is available through several online channels. Author summary In biological and other types of experiments, we frequently record changes of some parameters in time or space. It is common to analyze the data by splitting the recording into smaller sections and relating it to some changes induced by the researchers. The steps involved in the analysis are: splitting of the data, fitting them to some function, relating the fit result to the change in the environment, and normalization. These steps are frequently done through several software packages, spreedsheets, and manual copy and paste between the programs. The software presented in this work allows to make all these analysis steps in one database in a manner that is easy, can be reproduced by others, and clearly tracks the history of all the analysis steps. In addition, it allows to link the experimental data with the description of the experiment, making it simple to perform tasks such as normalization of the recorded values, relating experimental recordings to the sample or animal, as well as extracting data from the laboratory database for publishing. The software is written to be easily extendable by user-defined modules to fit the analysis pipelines and is expected to improve the data analysis practices in research.","2020-12","2025-04-25 15:29:30","2025-04-25 15:29:30","","","","12","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The software currently calculates 797 descriptors (663 1D, 2D descriptors, and 134 3D descriptors) and 10 types of fingerprints. These descriptors and fingerprints are calculated mainly using The Chemistry Development Kit. Some additional descriptors and fingerprints were added, which include atom type electrotopological state descriptors, McGowan volume, molecular linear free energy relation descriptors, ring counts, count of chemical substructures identified by Laggner, and binary fingerprints and count of chemical substructures identified by Klekota and Roth. Methods: PaDEL-Descriptor was developed using the Java language and consists of a library component and an interface component. The library component allows it to be easily integrated into quantitative structure activity relationship software to provide the descriptor calculation feature while the interface component allows it to be used as a standalone software. The software uses a Master/Worker pattern to take advantage of the multiple CPU cores that are present in most modern computers to speed up calculations of molecular descriptors. Results: The software has several advantages over existing standalone molecular descriptor calculation software. It is free and open source, has both graphical user interface and command line interfaces, can work on all major platforms (Windows, Linux, MacOS), supports more than 90 different molecular file formats, and is multithreaded. Conclusion: PaDEL-Descriptor is a useful addition to the currently available molecular descriptor calculation software.

Moreover, society may greatly benefit when software originators choose an open-source development strategy as their products become widely available, readily customizable, and open to community contributions. In this study, we present an economic model to study how software licensing attributes affect a software originator's decisions, aiming to provide policy makers with insights into how welfare-improving, open-source outcomes can be incentivized. We show that when a competing contributor is apt at reaping the benefits of software development investment, a less restrictive open source license (e.g., Berkeley Software Distribution, or BSD style) can improve welfare. On the other hand, when the originator is better at leveraging investment and service costs are high, a more restrictive license (e.g., General Public License, or GPL style) can be best for social welfare even when a contributor can cost-efficiently develop the software.","2018-03","2025-04-25 15:29:30","2025-04-25 15:29:30","","186-205","","1","29","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite recent advances in imaging techniques, the application of unbiased computational image analysis methods for morphodynamic quantification is rare. For example, manual analysis using kymographs is still commonplace, often caused by lack of access to user-friendly, automated tools. We now describe software designed for the automated quantification of cell migration and morphodynamics. Implemented as a plug-in for the open-source platform, ImageJ, ADAPT is capable of rapid, automated analysis of migration and membrane protrusions, together with associated fluorescently labeled proteins, across multiple cells. We demonstrate the ability of the software by quantifying variations in cell population migration rates on different extracellular matrices. We also show that ADAPT can detect and morphologically profile filopodia. Finally, we have used ADAPT to compile an unbiased description of a “typical” bleb formed at the plasma membrane and quantify the effect of Arp2/3 complex inhibition on bleb retraction.","2015-04-13","2025-04-25 15:29:30","2025-04-25 15:29:30","","163-180","","1","209","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This quality degradation effect, called entropy, is a cause for higher maintenance costs. In the Open Source context, the quality of code is a fundamental tenet of open software developers. As a consequence, the quality degradation principle measured by entropy cannot be assumed to be valid. The goal of the paper is to analyze the entropy of Open Source applications by measuring the evolution of maintenance costs over time. Analyses are based on cost data collected from a sample of 1251 Open Source application versions, compared with the costs estimated with a traditional model for proprietary software. Findings indicate that Open Source applications are less subject to entropy, have lower maintenance costs and also a lower need for maintenance interventions aimed at restoring quality. Finally, results show that a lower entropy is favored by greater functional simplicity.","2007","2025-04-25 15:29:31","2025-04-25 15:29:31","","34-43","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE; IEEE Comp Soc; IEEE France Sect; TCSE; IEEE Comp Soc, Tech Council Software Engn; Reeng Forum; Univ Waterloo; Univ Studi Sannio","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.","2015-03","2025-04-25 15:29:31","2025-04-25 15:29:31","","224-237","","1","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them.

However, the problematic nature of OSS adoption is readily evidenced in the fairly frequent reports of problems, unforeseen hold-ups, and outright abandonment of OSS implementation over time. Beaumont Hospital, an Irish public sector organization, have embarked on the adoption of a range of OSS applications over several years, some of which have been successfully deployed and remain in live use within the organisation, whereas others, despite achieving high levels of assimilation over a number of years, have not been ultimately retained in live use in the organization. Using a longitudinal case study, we discuss in depth the deployment process for two OSS applications - the desktop application suite whose deployment was unsuccessful ultimately, and the email application which was successfully deployed. To our knowledge, this is the first such in-depth study into successful and unsuccessful OSS implementation. Given that our study was a longitudinal one in a single organization, we can control a number of potentially important influencing elements which would not be possible if multiple organizations were involved. In particular, the complex interaction of issues to do with voluntariness of adoption, image, trialability and absorptive capacity were critical influences in the process.","2007","2025-04-25 15:29:31","2025-04-25 15:29:31","","IS33","","","","","","","","","","","INSTICC; Workflow Management Coalit; Interdisciplinary Inst Collaborat & Res Enterprise Syst & Technol","","","","","","","","","","","","","","","Filipe, J; Helfert, M; Shishkov, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One fruitful approach to studying this process is to record from neurons using patch-clamp electrodes, fill the recorded neurons with a substance that allows subsequent staining, reconstruct the three-dimensional architectures of the dendrites, and use the resulting functional and structural data to develop computer models of dendritic integration. Accurately producing quantitative reconstructions of dendrites is typically a tedious process taking many hours of manual inspection and measurement. Here we present ShuTu, a new software package that facilitates accurate and efficient reconstruction of dendrites imaged using bright-field microscopy. The program operates in two steps: (1) automated identification of dendritic processes, and (2) manual correction of errors in the automated reconstruction. This approach allows neurons with complex dendritic morphologies to be reconstructed rapidly and efficiently, thus facilitating the use of computer models to study dendritic structure-function relationships and the computations performed by single neurons.","2019-10-31","2025-04-25 15:29:31","2025-04-25 15:29:31","","","","","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here we introduce AxonSeg, which allows to perform automatic axon and myelin segmentation on histology images, and to extract relevant morphometric information, such as axon diameter distribution, axon density and the myelin g-ratio. AxonSeg includes a simple and intuitive MATLABbased graphical user interface (GUI) and can easily be adapted to a variety of imaging modalities. The main steps of AxonSeg consist of: (i) image pre-processing; (ii) pre-segmentation of axons over a cropped image and discriminant analysis (DA) to select the best parameters based on axon shape and intensity information; (iii) automatic axon and myelin segmentation over the full image; and (iv) atlas-based statistics to extract morphometric information. Segmentation results from standard optical microscopy (OM), SEM and coherent anti-Stokes Raman scattering (CARS) microscopy are presented, along with validation against manual segmentations.

Many previous works are developer-centric and overlook the importance of end-user forums. As a result, end-users' expectations are seldom reflected in OSS development. To better understand user behaviors in OSS user forums, we carried out an empirical study analyzing about 1.3 million posts from user forums of four popular OSS applications: Zotero, Audacity, VLC, and RStudio. Through analyzing the contribution patterns of three common user types (end-users, developers, and organizers), we observed that end-users not only initiated most of the threads (above 96% of threads in three projects, 86% in the other), but also acted as the significant contributors for responding to other users' posts, even though they tended to lack confidence in their activities as indicated by psycho-linguistic analyses. Moreover, we found end-users more open, reflecting a more positive emotion in communication than organizers and developers in the forums.

However, there were few developers being paid directly for maintaining OSS projects in the past. The GitHub Sponsors program that brings financial supports to the general OSS developers in GitHub-the world's largest OSS platform may make a difference on this situation in the future. In this paper, we present a data set on GitHub Sponsors and conduct a data-driven study to analyze the participants of the program and the impact of sponsorships to developers' activities and their projects' outcomes and qualities. The results of our survey suggest that most developers state they will contribute more with sponsorships and provide some privilege for their sponsors. And through quantitative study, we find that developers make more contributions on GitHub after they got/offered sponsorships. Moreover, gaining sponsorship also has a weakly positive impact on developers' collaborators that did not get sponsorship. And not only developers, but their own or contributed projects also can be motivate by sponsorships. Our findings are useful to the community by understanding the impact of sponsorships on users' activities and projects' progress and sustainability, and helping the managers to improve the current financial support mechanism.","2022","2025-04-25 15:29:31","2025-04-25 15:29:31","","924-933","","","","","","","","","","","IEEE; IEEE Comp Soc","","","","","","","","","","","","","","","Leong, HV; Sarvestani, SS; Teranishi, Y; Cuzzocrea, A; Kashiwazaki, H; Towey, D; Yang, JJ; Shahriar, H","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Cross-language software similarity detection is inherently more challenging due to variations in language, application structures, support libraries used, and naming conventions. In this paper we propose a novel model, CroLSim, to detect similar software applications across different programming languages. We define a semantic relationship among cross-language libraries and API methods (both local and third party) using functional descriptions and a word-vector learning model. Our experiments show that CroLSim can successfully detect cross-language similar software applications, which outperforms all existing approaches (mean average precision rate of 0.65, confidence rate of 3.6, and 75% highly rated successful queries). Furthermore, we applied CroLSim to a source code repository to see whether our model can recommend cross-language source code fragments if queried directly with source code. From our experiments we found that CroLSim can recommend cross-language functional similar source code when source code is directly used as a query (average precision=0.28, recall=0.85, and F-Measure=0.40).

Excel is used as the front end for the software, which is written in Visual Basic. Case studies are used to demonstrate the broad range of structures that can be designed using the software, including: precisely controlled specimens for printer calibration, parametric specimens for hardware characterisation utilising hundreds of unique parameter combinations, novel mathematically defined lattice structures, and previously inconceivable 3D geometries that are impossible for traditional slicing software to achieve. The FullControl design approach enables unconstrained freedom to create nonplanar 3D print-paths and break free from traditional restrictions of layerwise print-path planning. It also allows nozzle movements to be carefully designed both during extrusion and while travelling between disconnected extrusion volumes - to overcome inherent limitations of the printing process or to improve capabilities for challenging materials. An industrial case study shows how explicit print-path design improved printer reliability, production time, and print quality for a production run of over 1000 parts. FullControl GCode Designer offers a general framework for unconstrained design and is not limited to a particular type of structure or hardware; transferability to lasers and other manufacturing processes is discussed. Parametric design files use a few bytes or kilobytes of data to describe all details that are sent to the printer, which greatly improves shareability by eliminating any risk of errors being introduced during STL file conversion or due to different users having inconsistent slicer settings. Adjustable parameters allow GCode for revised designs to be produced instantly, instead of the laborious traditional routine using multiple software packages and file conversions. The FullControl design concept offers new opportunities for creative and high-precision use of additive manufacturing systems. It facilitates design for additive manufacturing (DfAM) at the smallest possible scale based on the fundamental nature of the process (i.e. assembly of individual extrusions). The software and source code are provided as supplementary data and ongoing updates to improve functionality and the user interface will be available at www.fullcontrolgcode.com.","2021-10","2025-04-25 15:29:32","2025-04-25 15:29:32","","","","","46","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we give an update the state of knowledge to the current situation of gender in FLOSS, by analyzing the results of surveying more than 2,000 contributors to FLOSS projects in 2013, of which more than 200 were women. Our findings confirm that women enter the FLOSS community later than men, do primarily other tasks than coding, participate less if they have children, and have slightly different reasons to enter (and to stay in) the development communities they join. However, we also find evidence that women are joining FLOSS projects in higher numbers in recent years, and that the share of women devoting few hours per week to FLOSS and full-time dedication is higher than for men. All in all, comparing our results with the ones from the 2000s, the context of participation of women in FLOSS has not changed much.","2016","2025-04-25 15:29:32","2025-04-25 15:29:32","","163-173","","","472","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 2 13; Software Ctr; Informat & Commun Technol; Business Reg Goteborg","","","","","","","","","ISSN: 1868-4238","","","","","","Crowston, K; Hammouda, I; Lundell, B; Robles, G; Gamalielsson, J; Lindman, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open source software (OSS) has challenged much of the traditional reasoning by suggesting that individuals behave altruistically and contribute to a public good, despite the opportunity to free-ride. The lion's share of the existing literature on OSS examines communities, that is, those individuals whom are already part of the OSS community. In contrast, this paper starts from users with the requisite skill to use and develop OSS. This group of skilled individuals could potentially invest into the development of OSS knowledge, but they may or may not do so in actuality. This paper, therefore, explores three issues, which have not been extensively explored in the literature, namely, (1) how frequently a group of skilled people use OSS, (2) reasons for differences among users and non-users in terms of use and attitudes, and (3) how frequently, and why, some users contribute to OSS projects (and thereby become developers). In doing so, we consider the opportunity costs of use and development of OSS, which has been largely neglected in the literature. We find that the individuals have a rather pragmatic attitude to firms and that many are active in both firms and OSS community, which raises many questions for future research about the role and influence of firms on the development and diffusion of OSS.","2005","2025-04-25 15:29:32","2025-04-25 15:29:32","","617-635","","7","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software is a recent and important example. Copyright restrictions on open-source projects stipulate that any user may modify the software so long as any resulting innovation is freely available to all. In economic parlance, the innovation is a public good. The economic theory of public-good provision raises a number of important questions. Who contributes to such a project, and who free rides? How might a social planner exploit the interdependence of project components to encourage contributions? Under what conditions will such actions result in successful provision? Using a simple game-theoretic framework and recent results from the study of equilibrium selection, we attempt to answer these questions. Under reasonable assumptions of asymmetry and less than complete information, the most efficient providers will contribute. Contributions can be elicited by `integrating' the provision process when providers are sufficiently optimistic about the success of the project. Otherwise, the social planner may be better off `separating' the components so that individual contributions are independent of each other. The analysis yields recommendations for the leaders of open-source projects and other similar collective-action problems.","2002","2025-04-25 15:29:32","2025-04-25 15:29:32","","446-461","","4","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The explosion of the World Wide Web, dynamic nature of information technologies, like open source; and with escalation of electronics resources showed the way of Automated Library System (ALS). These changes are replicated in the conceptual differences between the ALS and the Integrated Library System (ILS). The ALS is acknowledged as simply a database to house and retrieve a library's holdings while ILS is acknowledged as robust clusters of systems including every process and module linked to library processes. This article presents an aspect on the evolving features of some commonly adopted Open-Source ILS Software (Koha, NewGenLib, and Evergreen) which had encouraged ALS to ILS, as well as justifications and barriers to the use of open source. Open source library management software is a solution to reducing that cost. The research describes in brief about the feature of some of the open source digital library software like Greenstone, DSpace E-Prints and integrated library software Koha NewGenlib. Evergreen ILS etc., which are useful for developing ILS and institutional repositories software in academic libraries. Free and Open Source Software (FOSS) is offered as a balancing solution to meet librarians' objectives without giving up excellence.

Especially, OSS (Open Source Software) systems which serve as key components of critical infrastructures in the society are still ever-expanding now. We focus on OSS developed under open source project. In case of considering the effect of the debugging process on an entire system in the development of a method of reliability assessment for open source project, it is necessary to grasp the deeply-intertwined factors, such as programming path, size of each component, skill of fault reporter, and so on. In order to consider the effect of each software component on the reliability of an entire system under such open source software development, we propose a new approach to software reliability assessment by creating a fusion of neural networks and a software reliability growth model. Also, it has been necessary to manage the software development process in terms of reliability, effort, and version-upgrade time. In this paper, we find the optimal total version-upgrade time based on the total expected software maintenance effort.","2007","2025-04-25 15:29:32","2025-04-25 15:29:32","","53+","","","","","","","IEEE International Conference on Systems Man and Cybernetics Conference Proceedings","","","","IEEE","","","","","","","","","ISSN: 1062-922X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article systematically maps, aggregates, and synthesizes the state-of-the-art on women's participation in OSS. It focuses on women contributors' representation and demographics, how they contribute, their motivations and challenges, and strategies employed by communities to attract and retain women. We identified 51 articles (published between 2000 and 2021) that investigated women's participation in OSS. We found evidence in these papers about who are the women who contribute, what motivates them to contribute, what types of contributions they make, challenges they face, and strategies proposed to support their participation. According to these studies, only about 5% of projects were reported to have women as core developers, and women authored less than 5% of pull-requests, but had similar or even higher rates of pull-request acceptances than men. Women make both code and non-code contributions, and their motivations to contribute include learning new skills, altruism, reciprocity, and kinship. Challenges that women face in OSS are mainly social, including lack of peer parity and non-inclusive communication from a toxic culture. We found 10 strategies reported in the literature, which we mapped to the reported challenges. Based on these results, we provide guidelines for future research and practice.","2022-10","2025-04-25 15:29:32","2025-04-25 15:29:32","","","","4","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Like financial debt, it consists of the principal and an interest. Debt is usually paid back through code rewrites, refactoring, or the introduction of test code. When unchecked, interest can accumulate over time and lead to development crises where focus and resources must be shifted to resolve existing debt before the development process can be resumed. Existing software tooling allows practitioners to quantify the level of debt and identify its sources, allowing decision makers to measure and control it. We propose a detailed exploration of the characteristics of source code technical debt over the lifetime of several popular open-source applications. We employed a SonarQube instance configured for longitudinal analysis to study all publicly released versions of the target applications, amounting to over 15 years' worth of releases for each. We found that a small number of issue types were responsible for most of the debt and observed that refactoring reduced debt levels across most application packages. We observed increased variance in technical debt distribution and composition in early application versions, which lessened once applications matured. We addressed concerns regarding the accuracy of SonarQube estimations and illustrated some of its limitations. We aim to continue our research by including additional tools to characterize debt, leverage existing open data sets and extend our exploration to include additional applications and types of software.","2023","2025-04-25 15:29:32","2025-04-25 15:29:32","","292-314","","","1829","","","","Communications in Computer and Information Science","","","","INSTICC","","","","","","","","","ISSN: 1865-0929","","","","","","Kaindl, H; Mannion, M; Maciaszek, LA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the same time, it is important to understand which issues practitioners face when they are using a specific open source license, when they are developing new open source software products or when they are reusing open source software. In this work, we examine questions posed about open source software licensing using data from the following Stack Exchange sites: Stack Overflow, Software Engineering, Open Source and Law. We analyze the indication of specific licenses and topics in the questions, investigate the attention the posts receive and trends over time, whether appropriate answers are provided and which type of questions are asked. Our results indicate that practitioners need, among other, clarifications about licensing specific software when other licenses are used, and for understanding license content. The results of the study can be useful for educators and employers, organizations that are authoring open source software licenses and developers for understanding the issues faced when using licenses, whereas they are relevant to other software engineering research areas, such as software reusability.

In particular, sensor data sharing, known as cooperative perception, is a crucial technique to accommodate vulnerable road users in a cooperative intelligent transport system (ITS). In this regard, open-source software plays a significant role in prototyping, validation, and deployment. Specifically, in the developer community, Autoware is a popular open-source software for self-driving vehicles, and OpenC2X is an open-source experimental and prototyping platform for cooperative ITS. This paper reports on a system named AutoC2X to enable cooperative perception by using OpenC2X for Autoware-based autonomous vehicles. The developed system is evaluated by conducting field experiments involving real hardware. The results demonstrate that AutoC2X can deliver the cooperative perception message within 100 ms in the worst case.","2020","2025-04-25 15:29:33","2025-04-25 15:29:33","","","","","","","","","IEEE Vehicular Technology Conference VTC","","","","IEEE; IEEE Vehicular Technol Soc","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This results in multiple versions or evolving nature of a software. Identification of parts of a software that are more prone to changes than others is one of the important activities. Identifying change prone classes will help developers to take focused and timely preventive actions on the classes of the software with similar characteristics in the future releases. In this paper, we have studied the relationship between various object oriented (OO) metrics and change proneness. We collected a set of OO metrics and change data of each class that appeared in two versions of an open source dataset, `Java TreeView', i.e., version 1.1.6 and version 1.0.3. Besides this, we have also predicted various models that can be used to identify change prone classes, using machine learning and statistical techniques and then compared their performance. The results are analyzed using Area Under the Curve (AUC) obtained from Receiver Operating Characteristics (ROC) analysis. The results show that the models predicted using both machine learning and statistical methods demonstrate good performance in terms of predicting change prone classes. Based on the results, it is reasonable to claim that quality models have a significant relevance with OO metrics and hence can be used by researchers for early prediction of change prone classes.","2013-12","2025-04-25 15:29:33","2025-04-25 15:29:33","","","","6, SI","20","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This surge in unmanned aerial vehicles has increased attention towards monitoring tasks in vital areas, such as urban spaces for security, surveillance or Internet of the Things applications. In this sense, we propose an open-source software-in-the-loop approach that integrates the complete navigation experience, accounting for potential wind-related effects, and providing realistic 3D modeling of scenarios encompassing open spaces in city landscapes. Our work introduces a wind perturbation estimation strategy, which models the wind effect as an external force along the Zaxis based on altitude variations from real flights. Validation was conducted using real data flights with a quadrotor aiding the navigation with Ardupilot and QgroundControl as a ground station. To complement the experiments we include a small test with a fixed-wing plane to asses the software-in-the-loop accuracy on larger trajectories. Results demonstrate successful tracking of altitude variations, yielding errors below 10% relative to the home position in experiments with average trajectory lengths of 150 m in two scenarios in Quito. The software-in-the-loop simulation aimed to replicate wind conditions specific to the date and time of real data acquisition, providing a platform to emulate possible improvements and assess UAV performance before deployment in actual missions. This research not only contributes to the optimization of monitoring capabilities but also serves as a valuable tool for assessing UAV missions in diverse and dynamic environments.","2024","2025-04-25 15:29:33","2025-04-25 15:29:33","","1453-1460","","","","","","","International Conference on Unmanned Aircraft Systems","","","","IEEE","","","","","","","","","ISSN: 2373-6720","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although a plethora of software for the acquisition of eye-tracking data exists, they often exhibit critical issues when pervasive eye tracking is considered, e. g., closed source, costly eye tracker hardware dependencies, and requiring a human supervisor for calibration. In this paper, we introduce EyeRecToo, an open-source software for real-time pervasive head-mounted eye-tracking. Out of the box, EyeRecToo offers multiple real-time state-of-the-art pupil detection and gaze estimation methods, which can be easily replaced by user implemented algorithms if desired. A novel calibration method that allows users to calibrate the system without the assistance of a human supervisor is also integrated. Moreover, this software supports multiple head-mounted eye-tracking hardware, records eye and scene videos, and stores pupil and gaze information, which are also available as a real-time stream. Thus, EyeRecToo serves as a framework to quickly enable pervasive eye-tracking research and applications.

This focus on growth generated by the community is referred to as “single factor” growth and is an assumption shared by literature on the diffusion of innovation. The purpose of this research is to attempt to fit a logistic model to a well-known OSS project as a confirmatory exercise supporting the use of a single factor growth model as suggested by the literature. The results show that a logistic model, or any kind of single factor model, is inadequate to describe the diffusion of the OSS project. The paper then explains conceptually and illustrates mathematically why single factor models cannot fully represent the diffusion of any OSS project. A well-known two-factor model drawn from the marketing literature is presented, shown to solve the problem of single factor models, and used to illustrate the importance of marketing in OSS projects. This research suggests that the OSS literature may be overemphasizing the importance of the size of the user and developer community during the initial stages of growth and that during these stages the diffusion of the OSS project is primarily driven by external forces such as advertising or marketing efforts.","2009","2025-04-25 15:29:33","2025-04-25 15:29:33","","91-101","","2","38","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, in the field of civil engineering, the use of structural reliability methods unfortunately remains limited to specific cases. Most of the software available has still a limited range concerning wide parametric studies for analysis with reliability methods in civil engineering. This paper describes a new open-source software library as an effective tool for reliability analysis in civil engineering. The goal is to facilitate the adoption of reliability methods among engineers in practice as well as to provide an open platform for further scientific collaboration. The new library is being developed as a so-called “R package” in open-source programming software “R”. The package is capable of carrying out systematic parameter studies using different probabilistic reliability methods, as FORM, SORM, Monte Carlo Simulation. Based on this, an overview on the probabilistic reliability methods implemented in the package as well as results of parametric studies is given. The performance of the package will be shown with a parametric study on a practical example. Most important results of the parametric study as well as the correctness of different reliability methods will be described in the paper. By describing probabilistic methods using an example in practice, engineers can get a basic understanding behind the ideas of probability theories. Further work will result in large parameter studies, which will support the development of a new guideline for reliability in civil engineering. This guideline describes techniques of code calibration as well as to determine new partial safety factors (e.g. for non-metallic reinforced concrete, fixing anchors, etc.). Furthermore, advanced reliability methods (e.g. Monte Carlo with Subset Sampling) will be implemented in the new R package.","2021","2025-04-25 15:29:33","2025-04-25 15:29:33","","405-415","","","153","","","","Lecture Notes in Civil Engineering","","","","Univ Minho; Inst Sustainabil & Innovat Structural Engn","","","","","","","","","ISSN: 2366-2557","","","","","","Matos, JC; Lourenco, PB; Oliveira, DV; Branco, J; Proske, D; Silva, RA; Sousa, HS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper develops a framework of the OSS community ideology (including specific norms, beliefs, and values) and a theoretical model to show how adherence to components of the ideology impacts effectiveness in OSS teams. The model is based on the idea that the tenets of the OSS ideology motivate behaviors that enhance cognitive trust and communication quality and encourage identification with the project team, which enhances affective trust. Trust and communication in turn impact OSS team effectiveness. The research considers two kinds of effectiveness in OSS teams: the attraction and retention of developer input and the generation of project outputs. Hypotheses regarding antecedents to each are developed. Hypotheses are tested using survey and objective data on OSS projects. Results support the main thesis that OSS team members' adherence to the tenets of the OSS community ideology impacts OSS team effectiveness and reveal that different components impact effectiveness in different ways. Of particular interest is the finding that adherence to some ideological components was beneficial to the effectiveness of the team in terms of attracting and retaining input, but detrimental to the output of the team.

The absence of comprehensive security assessment as well as a consolidated and ubiquitous roadmap for vulnerability patching and security hardening, makes open-source solution a risk for widespread enterprise use. This paper introduces a security assurance approach which addresses open-source hardware and software shortcoming in an end-to-end manner, by providing a logical decomposition of any such module into four distinct component layers: device, network, application and cognitive. This allows highly focused security assessment, taking into consideration the specific characteristics of each layer. In addition, the paper provides an approach on how open-source solution security can be improved, through decomposition, layered vulnerability mitigation and specialized security hardening techniques.

Such models can be used for patient and trainee education, and potentially for surgical planning. Currently, 3-D printed models are more commonly used, but they are static, showing only one selected phase of the cardiac cycle. Second, they are limited by the selection of clipping planes before printing. Four-dimensional segmentation and virtual reality visualization overcome these limitations.

The critical issue in robot audition is real-time processing in noisy environments with high flexibility to support various kinds of robots and hardware configurations. This paper presents open-source robot audition software, called “HARK”, which includes sound source localization, separation, and automatic speech recognition (ASR). Since separated sounds suffer from spectral distortion due to separation, HARK generates a temporal-frequency map of reliability called “missing feature mask”, for features of separated sounds. Then separated sounds are recognized by the Missing-Feature Theory (MFT) based ASR with missing feature masks. HARK is implemented on the middleware called “FlowDesigner” to share intermediate audio data, which provides real-time processing. HARK's performance in recognition of noisy/simultaneous speech is shown by using three humanoid robots, Honda ASIMO, SIG2 and Robovie with different microphone layouts.","2008","2025-04-25 15:29:34","2025-04-25 15:29:34","","709-714","","","","","","","IEEE-RAS International Conference on Humanoid Robots","","","","IEEE; RAS","","","","","","","","","ISSN: 2164-0572","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Root characteristics like length, diameter and volume are critical to measure to understand plant and soil functions. RhizoVision Explorer is an open-source software designed to enable researchers interested in roots by providing an easy-to-use interface, fast image processing and reliable measurements. The default broken roots mode is intended for roots sampled from pots and soil cores, washed and typically scanned on a flatbed scanner, and provides measurements like length, diameter and volume. The optional whole root mode for complete root systems or root crowns provides additional measurements such as angles, root depth and convex hull. Both modes support providing measurements grouped by defined diameter ranges, the inclusion of multiple regions of interest and batch analysis. RhizoVision Explorer was successfully validated against ground truth data using a new copper wire image set. In comparison, the current reference software, the commercial WinRhizo (TM), drastically underestimated volume when wires of different diameters were in the same image. Additionally, measurements were compared with WinRhizo (TM) and IJ_Rhizo using a simulated root image set, showing general agreement in software measurements, except for root volume. Finally, scanned root image sets acquired in different labs for the crop, herbaceous and tree species were used to compare results from RhizoVision Explorer with WinRhizo (TM). The two software showed general agreement, except that WinRhizo (TM) substantially underestimated root volume relative to RhizoVision Explorer. In the current context of rapidly growing interest in root science, RhizoVision Explorer intends to become a reference software, improve the overall accuracy and replicability of root trait measurements and provide a foundation for collaborative improvement and reliable access to all.","2021-09-13","2025-04-25 15:29:34","2025-04-25 15:29:34","","","","6","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These experiments are executed by training the model under observation with varying configurations. Since executing a typical training run can take days even on proven acceleration fabrics such as Graphics Processing Units (GPU), properly managing training data, avoiding human error in configuration preparations and securing the repeatability of the experiments are of utmost importance. In this paper, we present two open source software tools that aim to achieve these goals, namely, a Dataset Manager (DatumAid) tool and a Training Automation Manager (OrchesTrain) tool. DatumAid is a software tool that integrates with Computer Vision Annotation Tool (CVAT) to facilitate the management of annotated datasets. By adding additional functionality, DatumAid allows users to filter labeled data, manipulate datasets, and export datasets for training purposes. The tool adopts a simple code structure while providing flexibility to users through configuration files. OrchesTrain aims to automate model training process by facilitating rapid preparation and training of models in the desired style for the intended tasks. Users can seamlessly integrate their models prepared in the PyTorch library into the system and leverage the full capabilities of OrchesTrain. It enables the simultaneous or separate usage of Wandb, MLflow, and TensorBoard loggers. To ensure reproducibility of the conducted experiments, all configurations and codes are saved to the selected logger in an appropriate structure within a YAML file along with the serialized model files. Both software tools are publicly available on GitHub.","2023","2025-04-25 15:29:34","2025-04-25 15:29:34","","1814-1818","","","","","","","IEEE ACM International Conference on Automated Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc","","","","","","","","","ISSN: 1527-1366","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For many applications, it is desirable to partition the measured fluxes into constitutive components: the water vapor flux into transpiration and direct evaporation components, and the carbon dioxide flux into photosynthesis and respiration components. The flux variance similarity (FVS) partitioning method is based on flux variance similarity relationships and correlation analyses of high-frequency eddy covariance data (Scanlon and Sahu, 2008; Scanlon and Kustas, 2010, 2012). The FVS method is relatively complex computationally, and that complexity has likely been an impediment to greater use and testing of the procedure. In this work, we present a new algebraic solution to the key computational task in the partitioning algorithm, which significantly simplifies the FVS method. We also introduce Fluxpart, a free and open source Python 3 module that implements the FVS partitioning procedure. Example flux partitioning calculations are presented.","2018-05-01","2025-04-25 15:29:34","2025-04-25 15:29:34","","218-224","","","253","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We introduce here a new open source software tool, rNMR, which provides a simple graphics-based method for visualizing, identifying, and quantifying metabolites across multiple one- or two-dimensional NMR spectra. rNMR differs from existing software tools for NMR spectroscopy in that analyses are based on regions of interest (ROIs) rather than peak lists. ROIs contain all of the underlying NMR data within user-defined chemical shift ranges. ROIs can be inspected visually, and they support robust quantification of NMR signals. ROI-based analyses support simultaneous views of metabolite signals from up to hundreds of spectra, and ROI boundaries can be adjusted dynamically to ensure that signals corresponding to assigned atoms are analyzed consistently throughout the dataset. We describe how rNMR greatly reduces the time required for robust bioanalytical analysis of complex NMR data. An rNMR analysis yields a compact and transparent way of archiving the results from a metabolomics study so that it can be examined and evaluated by others. The rNMR website at http://rnmr.nmrfam.wisc.edu offers downloadable versions of rNMR for Windows, Macintosh, and Linux platforms along with extensive help documentation, instructional videos, and sample data.

A recent literature has focused on the question of the business models explaining how and why firms may draw benefits from such involvement and their connected activities. They can be considered as the building blocks of a new modus operandi of an industry, built on an alternative approach to intellectual property management. Its prospects will depend on both the firms' willingness to rally and its ability to compete with the traditional `proprietary' approach. As a matter of fact, firms' involvement in FLOSS, while growing, remains very contrasted, depending on the nature of the products and the characteristics of the markets. This paper asks why for-profit firms contribute to FLOSS development and why some firms contribute more than others. The common explanation is that FLOSS is often a complement to proprietary software (or hardware or services) that the for-profit firm sells at a positive price. We present an alternative explanation based on the users' skill level. When users are skilled, opening the software is likely to result in a better product because the user base will contribute improvements (find bugs, write fixes and produce new features). We introduce the concept of the dominant user's skill and set up a theoretical model to better understand how it may condition the nature and outcome of the competition between a FLOSS firm and a proprietary firm. We discuss these results in the light of stylized facts drawn from recent trends in the software industry.

However, the problematic nature of OSS adoption is readily evidenced in the fairly frequent reports of problems, unforeseen hold-ups, and outright abandonment of OSS implementation over time. Beaumont Hospital, an Irish public sector organization, have embarked on the adoption of a range of OSS applications over several years, some of which have been successfully deployed and remain in live use within the organisation, whereas others, despite achieving high levels of assimilation over a number of years, have not been ultimately retained in live use in the organization. Using a longitudinal case study, we discuss in depth the deployment process for two OSS applications - the desktop application suite whose deployment was unsuccessful ultimately, and the email application which was successfully deployed. To our knowledge, this is the first such in-depth study into successful and unsuccessful OSS implementation. Given that our study was a longitudinal one in a single organization, we can control a number of potentially important influencing elements which would not be possible if multiple organizations were involved. In particular, the complex interaction of issues to do with voluntariness of adoption, image, trialability and absorptive capacity were critical influences in the process.","2007","2025-04-25 15:29:34","2025-04-25 15:29:34","","IS33","","","","","","","","","","","INSTICC; Workflow Management Coalit; Interdisciplinary Inst Collaborat & Res Enterprise Syst & Technol","","","","","","","","","","","","","","","Filipe, J; Helfert, M; Shishkov, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of biological sciences, information commons, such as public biobanks and free/libre open source software (FLOSS), are of paramount importance for both research and the bioeconomy. In a time of digitalization, however, information commons are vulnerable to violations, such as the free-rider problem, that render the commons unsustainable. Consequently, it has been argued that the enclosure of the informational common resources is the only means to effectively exploit them. Given the social and economic importance of the information commons, the new digital environment in biology and health requires governance innovation that will regulate the social embedding of the commons and their relationship to the free market, that is, a new political economy is needed. In this context, the need for a core common infrastructure, stretching from the physical to the logical and content layer of the information environment, that will guarantee the protection of the commons from both violations and enclosures, has been highlighted. Focusing on the interaction between two biological/bioinformatics commons, namely public biobanks and the FLOSS, we have set up an ecosystem relying on a blockchain technology. The proposed governance mechanism protects the information commons from the free-rider problem and guarantees their sustainability without hampering their operational framework. Our model demonstrates the interdependence and protection of the information commons not as an abstract theoretical exercise, but rather as a physical reality on the digital ontological matrix.","2020-05-01","2025-04-25 15:29:34","2025-04-25 15:29:34","","278-285","","5","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects.

As organizations increasingly contribute to and rely on OSS as part of their strategy, understanding how they can collaborate to build software holds importance for the future of software development. This study collects a unique dataset of development tasks from a large orgsOSS project spanning over two years and seven releases. Building on existing OSS research, we explore norms with respect to collaboration, i.e., how developers assign, discuss, and complete tasks, in an orgsOSS project. Interestingly, our analysis reveals that developers in orgsOSS do not always adhere to ideals of widespread sharing and participation espoused by traditional OSS, however some developer and task characteristics helped foster these ideals. Based on these and other findings, we develop a set of propositions and associated collaboration mechanisms that are important to future orgsOSS and other similarly structured software development projects.","2022-10-01","2025-04-25 15:29:34","2025-04-25 15:29:34","","3969-3987","","10","48","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In many urban areas (or agroecosystems), the practice of illegal waste disposing by commercial activities, by abandoning it in the countryside rather than spending economic resources to ensure correct disposal, is widespread. This causes an accumulation of waste in these areas (which can also be protected natural areas), which are then also set on fire to reduce their volume. Obviously, the repercussions of such actions are many. The burning of waste releases contaminants into the environment such as dioxins, polychlorinated biphenyls and furans, and deposits other elements on the soil, such as heavy metals, which, by leaching and percolating, contaminate water resources such as rivers and aquifers. The main objective is the design and implementation of monitoring programs against specific illicit activities that take into account territorial peculiarities. This advanced approach leverages AI and GIS environments to interpret environmental states, providing an understanding of ongoing phenomena. The methodology used is based on the implementation of mathematical and AI algorithms, integrated into a GIS environment to address even large-scale environmental issues, improving the spatial and temporal precision of the analyses and allowing the customization of monitoring programs in urban and peri-urban environments based on territorial characteristics. The results of the application of the methodology show the percentages of the different types of waste found in the agroecosystems of the study area and the degree of concentration, allowing the identification of similar areas with greater criticality. Subsequently, through network and nearest neighbour analysis, it is possible to start targeted checks.","2024-03","2025-04-25 15:29:34","2025-04-25 15:29:34","","","","1","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through a structured literature review, empirical surveys, and comparative analyses of projects like webpack and babel, the study develops a comprehensive set of metrics, including team health, project activity, and others. These metrics are quantified and validated, as demonstrated in a case study on AngularJs. The outcomes provide a novel framework for evaluating maintainability in open-source software, offering essential insights for sustainable development and maintenance within the complex environment of software supply chains.","2024","2025-04-25 15:29:34","2025-04-25 15:29:34","","220-231","","","","","","","IEEE Annual International Computer Software and Applications Conference","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 2836-3787","","","","","","Shahriar, H; Ohsaki, H; Sharmin, M; Towey, D; Majumder, AKMJA; Hori, Y; Yang, JJ; Takemoto, M; Sakib, N; Banno, R; Ahamed, SI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Another important part of spatial epidemiology is testing whether patients suffering from a disease are more, or less, exposed to environmental factors of interest than adequately defined controls. Both approaches involve determining the number of cases and controls (or population at risk) in specific zones. For cluster searches, this often must be done for millions of different zones. Doing this by calculating distances can lead to very lengthy computations. In this work we discuss the computational advantages of geographical grid-based methods, and introduce an open source software (FGBASE) which we have created for this purpose. Methods: Geographical grids based on the Lambert Azimuthal Equal Area projection are well suited for spatial epidemiology because they preserve area: each cell of the grid has the same area. We describe how data is projected onto such a grid, as well as grid-based algorithms for spatial epidemiological data-mining. The software program (FGBASE), that we have developed, implements these grid-based methods. Results: The grid based algorithms perform extremely fast. This is particularly the case for cluster searches. When applied to a cohort of French Type 1 Diabetes (T1D) patients, as an example, the grid based algorithms detected potential clusters in a few seconds on a modern laptop. This compares very favorably to an equivalent cluster search using distance calculations instead of a grid, which took over 4 hours on the same computer. In the case study we discovered 4 potential clusters of T1D cases near the cities of Le Havre, Dunkerque, Toulouse and Nantes. One example of environmental analysis with our software was to study whether a significant association could be found between distance to vineyards with heavy pesticide. None was found. In both examples, the software facilitates the rapid testing of hypotheses. Conclusions: Grid-based algorithms for mining spatial epidemiological data provide advantages in terms of computational complexity thus improving the speed of computations. We believe that these methods and this software tool (FGBASE) will lower the computational barriers to entry for those performing epidemiological research.","2014-10-30","2025-04-25 15:29:35","2025-04-25 15:29:35","","","","","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While prior research has explored the communal nature of open source software development among individual users, little research has explored whether these sharing concepts are also present in organizational use of open source software products. This study uses a theory integration approach to develop some initial insight into the differences between users and non-users of open source software. This study observed three groups of factors from six case studies of information sharing in the context of organizational open source software use. These factors were integrated with prior research in order to understand the physical and managerial barriers to, and enablers of, open source. The study proposes that open source users have more extensive knowledge sharing and teamwork practices in place, and are more tolerant of risk. The study also argues that open source users depended less on external technology support services but have more extensive information technology ( IT) support structures.

However, current CI/CD pipelines suffer from malicious code and severe vulnerabilities. Even worse, people have not been fully aware of its attack surfaces and the corresponding impacts. Therefore, in this paper, we conduct a large-scale measurement and a systematic analysis to reveal the attack surfaces of the CI/CD pipeline and quantify their security impacts. Specifically, for the measurement, we collect a data set of 320,000+ CI/CD pipeline-configured GitHub repositories and build an analysis tool to parse the CI/CD pipelines and extract security-critical usages. Our measurement reveals that the script runtimes are prone to code hiding while the script usage update is not in time, giving attackers chances to hide malicious code and exploit existing vulnerabilities. Moreover, even the scripts from verified creators may contain severe vulnerabilities. Besides current CI/CD ecosystem heavily relies on several core scripts, which may lead to a single point of failure. While the CI/CD pipelines contain sensitive information/operations, making them the attacker's favorite targets. Inspired by the measurement findings, we abstract the threat model and the attack approach toward CI/CD pipelines, followed by a systematic analysis of attack surfaces, attack strategies, and the corresponding impacts. We further launch case studies on five attacks in real-world CI/CD environments to validate the revealed attack surfaces. Finally, we give suggestions on mitigating attacks on CI/CD scripts, including securing CI/CD configurations, securing CI/CD scripts, and improving CI/CD infrastructure.","2024-01","2025-04-25 15:29:35","2025-04-25 15:29:35","","403-418","","1","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A business model perspective","JOURNAL OF ENTERPRISE INFORMATION MANAGEMENT","","1741-0398","10.1108/JEIM-05-2015-0041","","Purpose - Open Source software companies (OSSCs) are confronted with institutional pressures from Open Source software (OSS) communities. They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data. Design/methodology/approach - The methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample. Findings - The quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning. Research limitations/implications - The results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning. Practical implications - This study allows the authors to highlight two main practical contributions for OSSCs' directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables. Originality/value - This paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).","2017","2025-04-25 15:30:49","2025-04-25 15:30:49","","534-554","","4","30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We show that, contrary to standard predictions, additional contribution to the public good by the government or a new market entrant can lead to higher investments of all incumbent firms, that is, a crowding-in effect. This result occurs if the investment cost function is superadditive. We find that government contribution leads to larger crowding-in effects than subsidizing market entry if the price elasticity of demand with respect to the private good is large relative to the one with respect to the public good. Our results are robust to extensions in the timing and the mode of competition. (C) 2014 Elsevier B.V.

Governments and organizations are beginning to adopt OSS on a large scale and several governmental initiatives have encouraged the use of OSS in the private sector. One major issue for the government and private sector is the selection of appropriate OSS. This paper uses new internal quality characteristics for selecting OSS that can be added to the dimensions of DeLone and McLean information systems' model. Through this study, the quality characteristics are organized in a two level hierarchy, which list characteristics and sub-characteristics that are interconnected with three main dimensions: system quality, information quality and service quality. These characteristic dimensions are tailored to the criteria having been built from literature study and standard for software quality and guidelines. This paper presents case study results of applying the proposed quality characteristic on eight different open source software that are divided between open source network tools and learning management systems.

However, with the emergence of new environmental design tasks, addressing all possible use cases and tasks is challenging and cannot be covered by a single tool. Urban-scale analysis at this level of complexity often requires linking multiple emerging tools, rather than using a single tool, to adequately evaluate a variety of possible fields in urban environmental design. To achieve this, flexible platforms are needed to support multiple input formats (e.g., geometric and non-geometric building properties), enabling the mapping of such inputs to underlying simulation engines. This paper provides an overview of the open-source URBANopt Software Development Kit (SDK) for modeling high-performance buildings and energy systems at a district scale. URBANopt's flexible SDK is composed of several modules that can be customized to integrate with other tools and generate new workflows to perform urban environmental design tasks, such as capturing interactions between individual buildings, district energy systems, distributed energy resources, and the electric distribution grid. We describe the functionality of the core SDK modules in URBANopt (called Core Gem, GeoJSON Gem, and Scenario Gem) and discuss the flexibility of these modules as a means of integration with a variety of tools. We also document and demonstrate technical details of writing and combining new modules to create customized workflows. Finally, we present a case study that uses the URBANopt SDK to model a hypothetical mixed-use urban project and simulate various scenarios to meet district energy performance goals.","2020","2025-04-25 15:30:50","2025-04-25 15:30:50","","293-301","","","","","","","ASHRAE/IBPSA-USA Building Simulation Conference","","","","ASHRAE; IBPSA USA","","","","","","","","","ISSN: 2574-6308","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications.

A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field.

Each of these tools typically excels at one type of analysis, such as of microarrays, of metabolic networks and of predicted protein structure. A crucial challenge is to combine the capabilities of these (and other forthcoming) data resources and tools to create a data exploration and analysis environment that does justice to the variety and complexity of systems biology data sets. A solution to this problem should recognize that data types, formats and software in this high throughput age of biology are constantly changing. Results: In this paper we describe the Gaggle -a simple, open-source Java software environment that helps to solve the problem of software and database integration. Guided by the classic software engineering strategy of separation of concerns and a policy of semantic flexibility, it integrates existing popular programs and web resources into a user-friendly, easily-extended environment. We demonstrate that four simple data types (names, matrices, networks, and associative arrays) are sufficient to bring together diverse databases and software. We highlight some capabilities of the Gaggle with an exploration of Helicobacter pylori pathogenesis genes, in which we identify a putative ricin-like protein -a discovery made possible by simultaneous data exploration using a wide range of publicly available data and a variety of popular bioinformatics software tools. Conclusion: We have integrated diverse databases (for example, KEGG, BioCyc, String) and software (Cytoscape, DataMatrixViewer, R statistical environment, and TIGR Microarray Expression Viewer). Through this loose coupling of diverse software and databases the Gaggle enables simultaneous exploration of experimental data (mRNA and protein abundance, protein-protein and protein-DNA interactions), functional associations (operon, chromosomal proximity, phylogenetic pattern), metabolic pathways (KEGG) and Pubmed abstracts (STRING web resource), creating an exploratory environment useful to `web browser and spreadsheet biologists', to statistically savvy computational biologists, and those in between.

OSS requires firms to rethink the processes that facilitate value creation and capture. The objective of this paper is to theorise how firms create and capture value from OSS. We derive a model from extant research and refine it through the study of three inter-organisational networks. The findings reveal how a firm's ability to access a value network of complementors is crucial for effective value creation and capture. Two types of networks are evident: a high-density network of familiar partners and a low-density network of multiple, often unfamiliar, partners. Leveraging these networks depends on the level of commitment, volume of knowledge exchange and the alignment of objectives among participant firms. Effective governance is revealed as critical for creating and capturing value within both types of network; and depends on both formal and informal mechanisms.","2013-09","2025-04-25 15:30:50","2025-04-25 15:30:50","","569-588","","5, SI","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Findings: This study mainly finds that the presence of commercial open source software can lead to the decrease of the software price and profit for proprietary software producer, while the consumer surplus and social welfare will be increased. However, it does not necessarily cause the decline in the market share for proprietary software producer.

Their fate can be predicted using reactive transport models that describe reaction and advective and dispersive movement of these components in their natural environment. Recently a number of software packages have been implemented in the open source software R that allow one to implement reactive transport models. Central to this is the ReacTran R-package, a comprehensive collection of functions for modeling reactive components that may be distributed over multiple phases, whose dynamics are coupled through biological and geochemical reactions, and that are transported in one-, two- or three-dimensional domains with simple geometries. Dedicated solution methods are in R-packages deSolve and rootSolve. The modeling packages facilitate the simulation of reaction and transport of components for spatial scales ranging from micrometers to kilometers and spanning multiple time-scales. As they are influenced in similar ways, the same functions can solve biogeochemical models of the sediment, groundwater, rivers, estuaries, lakes or water columns, experimental setups, or even describe reaction and transport within flat, cylindrical or spherical bodies, such as organisms, aggregates, or the dispersion of individuals on flat surfaces and so on. We illustrate the use of R for reactive transport modeling by three applications spanning several orders of magnitude with respect to spatial and temporal scales. They comprise (1) a model of an experimental flow-through sediment reactor, where fitting so-called breakthrough curves are used to derive sulfate reduction rates in an estuarine sediment, (2) a conservative and reactive tracer addition experiment in a small stream, which implements the concept of river spiraling, and (3) a 2-D and 3-D model that describes oxygen dynamics in the upper layers of the sediment, interspersed with several hotspots of increased reaction intensities. The packages ReacTran, deSolve and rootSolve are implemented in the software R and thus available for all popular platforms (Linux, Windows, Mac). Models implemented using this software are short and easily readable, yet they are efficiently solved. This makes R extremely well suited for rapid model prototyping. (C) 2011 Elsevier Ltd.

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Design/methodology/approach - Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. Findings - There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and “tribal knowledge” that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. Originality/value - The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 15:30:50","2025-04-25 15:30:50","","211-223","","2","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, rising the GINI coefficient as a measure of inequality within the developer group.","2008-06","2025-04-25 15:30:50","2025-04-25 15:30:50","","31-57","","2","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project.

This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software. Design/methodology/approach A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76%. Findings The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff. Research limitations/implications This study is geographically limited to the university libraries in Islamabad. Practical implications This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries. Originality/value This study concludes that the development of IRs in university libraries is a need of the hour. Although the launching of IRs requires certain skills and competencies, Pakistani librarians can overcome these challenges by mastering the ICT skills.","2023-01-06","2025-04-25 15:30:51","2025-04-25 15:30:51","","47-55","","1","51","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For over a decade, the digital communities around the globe have used FOSS packages not only as an inexpensive way to access to information available on Internet, but also to disseminate thoughts, opinions and concerns about various socio-political and economic matters. Proxy servers and FOSS played a vital role in helping citizens in repressed countries to bypass the state imposed Internet content filtering and censorship practices. On the one hand, proxy servers act as redirectors to websites, and on the other hand, many of these servers are the main source for downloading FOSS anti-filtering software packages. These packages can provide secure web surfing via anonymous web access, data encryption. IP address masking, location concealment, browser history and cookie clean-ups but they also provide proxy software updates as well as domain name updates. The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In particular, they are poorly adapted to the slow Internet connections in many developing countries such as Iran. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.

A systematic literature review (SLR) is employed for the identification of potential risk factors in OSS whereas questionnaire survey is used to validate the findings of the SLR from the relevant expert community. In the second round another SLR is carried out to identify the practices for softening the effect of risk-factors in OSS development. A total of 14 risk factors from the developers' perspective are identified via SLR in OSS. Amid the risk factors identified bugs, insufficient product documentation, and lack of communication and coordination among developers are considered the most important Further, we performed a secondary SLR to identify the practices for mitigating the effects of the risk factors in OSS. Therefore, a total of 31 practices for mitigating and addressing the risk factors in OSS were identified. In this work, we identified 14 risk factors and 31 practices for mitigating the critical risk factors, through SLR for adapting OSS development from developers' perspectives. We argue that focusing on the identified risk factors would minimize the risks associated with OSS.

However, it has also brought important IT security risks that are impacting the OSS IT adoption decision-making process. The recent Heartbleed bug demonstrated the grandeur of the issue. While much of the noise relates to the amplification of perceived risks by the popular mass media coverage, the effect is that many enterprises, mainly for risk reasons, have still chosen not to adopt OSS. We investigated “how do information security related characteristics of OSS affect the risk perception and adoption decision of OSS” by conducting an online survey of 188 IT decision-makers. The proposed Open Source Risk Adoption Model offers novel insights on the importance of the perceived risk antecedents. Our research brings new theoretical contributions, such as understanding the perceived IT security risk (PISR) relationship with adoption intention (AI) in the OSS context, for researchers and important insights for IT information professionals.

Software documentation for these libraries is crucial in helping programmers/analysts know what libraries are available and how to use them. Yet documentation for open source software libraries is widely considered low-quality. This article is a collaboration between CSCW researchers and contributors to data analytics OSS libraries, based on ethnographic fieldwork and qualitative interviews. We examine several issues around the formats, practices, and challenges around documentation in these largely volunteer-based projects. There are many different kinds and formats of documentation that exist around such libraries, which play a variety of educational, promotional, and organizational roles. The work behind documentation is similarly multifaceted, including writing, reviewing, maintaining, and organizing documentation. Different aspects of documentation work require contributors to have different sets of skills and overcome various social and technical barriers. Finally, most of our interviewees do not report high levels of intrinsic enjoyment for doing documentation work (compared to writing code). Their motivation is affected by personal and project-specific factors, such as the perceived level of credit for doing documentation work versus more `technical' tasks like adding new features or fixing bugs. In studying documentation work for data analytics OSS libraries, we gain a new window into the changing practices of data-intensive research, as well as help practitioners better understand how to support this often invisible and infrastructural work in their projects.","2018-12","2025-04-25 15:30:51","2025-04-25 15:30:51","","767-802","","3-6, SI","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The dependence of OR on software implies that the ways in which software is developed, managed, and distributed can have a significant impact on the field. Open source is a relatively new software development and distribution model which offers advantages over current practices.

Respondents to an extensive web-survey's (FLOSS-US 2003) questions about their reasons for beginning to work FLOSS are classified according to their distinct “motivational profiles” by hierarchical cluster analysis. Over half of them also are matched to projects of known membership sizes, revealing that although some members from each of the clusters are present in the small, medium and large ranges of the distribution of project sizes, the mixing fractions for the large and the very small project ranges are statistically different. Among developers who changed projects, there is a discernable flow from the bottom toward the very small towards to large projects. some of which is motivated by individuals seeking to improve their programming skills. It is found that the profile of early motivation, along with other individual attributes, significantly affects individual developers' selections of projects from different regions of the size range.

The absence of GPS in extraplanetary environments prevents surface vehicles from knowing their exact location, which raises the need for an alternative positioning system. Traditional methods, such as visual odometry cross-referenced with digital elevation maps, are limited by their dependence on human input and pre-existing space infrastructure. This paper outlines and characterizes a global position determination algorithm intended for planetary surface vehicles in GPS-denied environments without any prior knowledge. The localization algorithm receives images of the stars from a visible camera and tilt measurements from an inclinometer, derives star locations and a gravity vector, and combines these signals to generate an onboard position determinant. This paper contributes (i) the first open-source planetary global localization algorithm based on stars, (ii) a sensor suite design derived of solely commercial-off-the-shelf (COTS) components, and (iii) an unprecedented physical experiment and characterization from this algorithm on Earth's surface. The resulting position determinant is on average 100km from the testing location, consistent across various time and surface inclines. This result is compared to theoretical performance, state-of-the-art sensor performance, and other global localization methods. This achieved determinant error offers a starting point toward localization improvement with more capable sensors and the incorporation of multiple historical determinants for state estimation.","2024","2025-04-25 15:30:52","2025-04-25 15:30:52","","158-164","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 %, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 %. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic. These insights provide various stakeholders, including individuals, organizations, and policymakers, with vital knowledge to prepare for future disruptions, foster sustainable resilience, and adeptly navigate the evolving landscape of remote work in a postpandemic world.","2023-12","2025-04-25 15:30:52","2025-04-25 15:30:52","","","","10","52","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, as the data becomes more complex and larger, SQL data processing becomes more difficult and costly. Typical problems include changing SQL queries and data schema resolution in complex dependencies by hand. In addition, human errors can lead to complex cyclic dependency problems. To mitigate these problems, we developed AlphaSQL: an open-source software tool for SQL data processing. AlphaSQL mainly supports three techniques to automate data preparation by SQL: (1) extracting a directed acyclic graph (DAG) based on dependencies between SQL and data, (2) validating the schema included in the whole DAG, and (3) parallelizing the queries based on the DAG. We applied AlphaSQL to a real-world data analysis and machine learning project where we analyzed 1445 logs obtained from static validation for git commits and 3243 execution logs. Our analysis showed that AlphaSQL detected various errors with high precision and recall, part of which existing tools could not catch (e.g., missing resources and schema mismatches). AlphaSQL would enable more maintainable data management using SQL.","2022","2025-04-25 15:30:52","2025-04-25 15:30:52","","38-45","","","","","","","IEEE International Conference on Data Engineering Workshop","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 1943-2895","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Consequently, software engineers are adopting pre-trained models (PTMs) for their downstream applications. The dynamics of the PTM supply chain remain largely unexplored, signaling a clear need for structured datasets that document not only the metadata but also the subsequent applications of these models. Without such data, the MSR community cannot comprehensively understand the impact of PTM adoption and reuse. This paper presents the PeaTMOSS dataset, which comprises metadata for 281,638 PTMs and detailed snapshots for all PTMs with over 50 monthly downloads (14,296 PTMs), along with 28,575 open-source software repositories from GitHub that utilize these models. Additionally, the dataset includes 44,337 mappings from 15,129 downstream GitHub repositories to the 2,530 PTMs they use. To enhance the dataset's comprehensiveness, we developed prompts for a large language model to automatically extract model metadata, including the model's training datasets, parameters, and evaluation metrics. Our analysis of this dataset provides the first summary statistics for the PTM supply chain, showing the trend of PTM development and common shortcomings of PTM package documentation. Our example application reveals inconsistencies in software licenses across PTMs and their dependent projects. PeaTMOSS lays the foundation for future research, offering rich opportunities to investigate the PTM supply chain. We outline mining opportunities on PTMs, their downstream usage, and crosscutting questions. Our artifact is available at https://github.com/PurdueDualityLab/PeaTMOSS-Artifact.

The study is conducted on 13 open source systems comprising over 14 MLOC. Each for-loop is statically analyzed to determine if it can be parallelized or not. A for-loop that can be parallelized is termed a free-loop. Free-loops can be easily parallelized using tools such as OpenMP. For the loops that cannot be parallelized, the various inhibitors to parallelization are determined and tabulated. The data shows that the most prevalent inhibitor by far, is functions called within for-loops that have side effects. This single inhibitor poses the greatest challenge in adapting and re-engineering systems to better utilize modern multi-core architectures. This fact is somewhat contradictory to the literature, which is primarily focused on the removal of data dependencies within loops. Results of this paper also show that function calls via function pointers and virtual methods have very little impact on the for-loop parallelization process. Historical data over a 10-year period of inhibitor counts for the set of systems studied is also presented. It shows that there is little change in the potential for parallelization of loops over time.","2016-06","2025-04-25 15:30:52","2025-04-25 15:30:52","","1272-1301","","3","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.","2016","2025-04-25 15:30:53","2025-04-25 15:30:53","","37-44","","","","","","","Proceedings of the European Conference on Knowledge Management","","","","","","","","","","","","","ISSN: 2048-8963","","","","","","Moffett, S; Galbraith, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.","2021-12-02","2025-04-25 15:30:53","2025-04-25 15:30:53","","","","12","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the 1850s, scientific writers including Auguste Comte, Herbert Spencer, and G. H. Lewes redefined biological life as dependent on an abstraction called a “medium” or “environment”- a term that united all the objects, substances, and forces in an organism's physical surroundings into a singular entity. Eliot in The Mill on the Floss draws out the ecological potential of this new biological concept by imbuing the described backgrounds of her novel with a lyrical affect I call “environmental desire,” a diffuse longing for ambient contact with one's formative medium that offers an ethical alternative to the possessive and object-driven forms of desire that drive the plot of a traditional Bildungsroman. Maggie Tulliver's marriage plot is structured by a tension between environmental desire and possessive desire, in which her erotic desire for Stephen Guest competes with a more diffuse environmental desire that attaches to the novel's described backgrounds. Ultimately, the new environment concept enables Eliot to reconceive the Bildungsroman's usual opposition between self and world as a relationship of nourishment and dependency rather than struggle, and invites a reconsideration of the ecological role of description in the Bildungsroman genre.","2021-09","2025-04-25 15:30:53","2025-04-25 15:30:53","","192-222","","2","76","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, high-quality code comments or method names are often unavailable due to tight project schedules or other reasons in open-source software ecosystems such as Github. Therefore, in this work, we try to use deep learning models to generate appropriate code comments or method names to help software development and maintenance, which requires a non-trivial understanding of the code. Therefore, we propose a Graph neural network enhanced Transformer model (GTrans for short) to learn code representation to understand code better. Specifically, GTrans learns code representation from code sequences and graphs. We use a Transformer encoder to capture the global representation from code sequence and a graph neural network (GNN) encoder to focus on the local details in the code graph, and then use a decoder to combine both global and local representations by attention mechanism. We use three public datasets collected from GitHub to evaluate our model. In an extensive evaluation, we show that GTrans outperforms the state-of-the-art models up to 3.8% increase in METEOR metrics on code comment generation and outperforms the state-of-the-art models by margins of 5.8%-9.4% in ROUGE metrics on method name generation after some adjustments on the structure. Empirically, we find the method name generation task depends on more local information than global, and the code comment generation task is in contrast.

Design/methodology/approach - Data were collected using a structured questionnaire, and semi-structured in-depth interviews were conducted among 20 academic and 20 research libraries in Beijing, China. The convenient sampling technique was used to collect data. The data collected were interpreted using descriptive statistics and independent t-test. Findings - The results reveal that Chinese research and academics libraries depend mostly upon commercial software and place a great deal of trust on locally produced free software. This situation may be caused due to the lack of professional knowledge in OSS and lack of appropriate technical expertise. Although there were a sufficient number of librarians who have shown interest in OSS, they did not enthusiastically agree to implement it in their libraries. Furthermore, the interviews highlighted the professionals' opinion that most librarians are reluctant to adopt OSS due to the risk factor, lack of professional expertise, insufficient interest of the Chinese Government and lack of professional training. Originality/value - The findings are useful for the Chinese LIS community, software developers, technology administrators and library administrators. In particular, it is beneficial for research and academic libraries of China to adapt OSS for library management and provide better library services and sources to their library users.","2018","2025-04-25 15:30:53","2025-04-25 15:30:53","","180-192","","3","67","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The topic of bugs has been extensively investigated and reported in the literature. Unfortunately, the existential question of all “whether a reported bug will be fixed or not” has not received much attention. The paper presents an empirical study on four open source projects to examine the factors that influence the likelihood of a bug getting fixed or not. Overall, our study can be contextualized as a conceptual replication of a previous study on Microsoft systems from a commercial domain. The similarities and differences in terms of the design, execution, and results between the two studies are discussed. It was observed from these systems that the reputations of the reporter and assigned developer to fix it, and the number of comments on a bug have the most substantial impact on its probability to get fixed. Moreover, we formulated a predictive model from features available as soon as a bug is reported to estimate whether it will be fixed or not. Intra and inter (cross) project validations were performed. Precision and Recall metrics were used to assess the predictive model. Their values were recorded in the 60% to 70% range.","2018","2025-04-25 15:30:53","2025-04-25 15:30:53","","299-310","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since supply chain vulnerabilities are a well-known concern, especially with open source systems, approaches in the literature mainly focus on identifying and patching such vulnerability. Frequently, however, a vulnerability patch is not immediately propagated to earlier releases that have been inherited by dependents, leaving residual vulnerabilities in supply chains. Our work addresses this challenge and develops a simple approach to iteratively explore the attack surface of supply chain residual vulnerabilities in open source projects. We have assessed our search scheme on 50 GitHub-hosted projects having high stars and forks: we mine their bug fix commits and identify buggy package versions to track the affected dependents and estimate the potential attack surface. We find that many projects fix their vulnerable issues by update their dependency versions, and version inheritance is a significant cause of supply chain attacks for open source projects.","2021","2025-04-25 15:30:53","2025-04-25 15:30:53","","493-502","","","","","","","IEEE International Conference on Software Quality Reliability and Security","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 2693-9185","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This feedback is generally reported in the form of new issues for the project, managed by the so-called issue-trackers. One of the features provided by most issue-trackers is the possibility to define a set of labels/tags to classify the issues and, at least in theory, facilitate their management. Nevertheless, there is little empirical evidence to confirm that taking the time to categorize new issues has indeed a beneficial impact on the project evolution. In this paper we analyze a population of more than three million of GitHub projects and give some insights on how labels are used in them. Our preliminary results reveal that, even if the label mechanism is scarcely used, using labels favors the resolution of issues. Our analysis also suggests that not all projects use labels in the same way (e.g., for some labels are only a way to prioritize the project while others use them to signal their temporal evolution as they move along in the development workflow). Further research is needed to precisely characterize these label “families” and learn more the ideal application scenarios for each of them.","2015","2025-04-25 15:30:53","2025-04-25 15:30:53","","550-554","","","","","","","","","","","Polytechnique Montreal, Dept Genie Informatique Genie Logiciel; Google Montreal; IEEE Comp Soc; Reengineering Forum; SAP Montreal Labs; Techn Council Software Engn; Tourisme Montreal","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The empirical study is conducted with the help of four open source datasets. Eleven bad smells are identified and is considered as maintenance effort. Results of this study show that GEP algorithm performs better than machine learning classifiers; hence it can be used as sound alternative in the prediction of software maintainability.

Many discussions have been aimed to decide whether or not OSS can be considered a COTS without reaching the unanimous consensus of the different international communities. This paper abandons any theoretical aspect of that question and focuses on the practical steps to follow when assembling component-based systems using also OSS components. All the activities normally performed when integrating COTS in a in-house built software are reviewed with the intention of underlining if the availability of the source code (and its possible exploitation) makes any difference. Moreover this article analyzes all the activities to perform when using OSS in a component-based system that are not necessary when using COTS. The purpose of this paper is to provide a guideline for the correct use of OSS within component-based systems, and not to answer whether OSS are considered or not COTS, leaving this task to the reader.","2005","2025-04-25 15:30:54","2025-04-25 15:30:54","","301-310","","","3412","","","","LECTURE NOTES IN COMPUTER SCIENCE","","","","European Software Inst; Carnegie Mellon Software Engn Inst; Natl Res Council Canada; Minist Educ & Ciencia; Bizkaiko Foru Aldundia; Diputac Foral Bizkaia","","","","","","","","","ISSN: 0302-9743","","","","","","Franch, X; Port, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The organizational commitment of OSS developers to quality is also explored. A comprehensive web-based questionnaire was completed by OSS and traditional developers. It was found that peer review is generally considered very useful for detecting both defects and flaws in code, as well as being important in contributing to the quality of the software. It is suggested that OSS developers commit to quality through internalization - adopting the ideas as their own, as the majority of the developers indicated that they would perform peer reviews without management direction. Encouragement to perform peer reviews and an organizational culture of peer review make it more likely for the developers to perform peer review under their own initiative, but neither are essential.","2002","2025-04-25 15:30:54","2025-04-25 15:30:54","","340-350","","","2349","","","","Lecture Notes in Computer Science","","","","Nokia Oyj; Amer Soc Qual; Helsinki Univ Technol; QPR Software Oyj Plc; SecGo Grp Oy; Siemens; Solid Informat Technol Oy; Sonera Oyj; Stonesoft Oyj; TietoEnator Oyj","","","","","","","","","ISSN: 0302-9743","","","","","","Kontio, J; Conradi, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, understanding how and why it occurs is important. To date, researchers have examined code reuse in OSS largely from the perspective of leaders. We show why followers must be considered as well. “Followers” are people who have had previous contacts with an individual from another project and who continue to associate with him or her. We consider two types of followers: developers (those directly involved in software development) and observers (those indirectly involved in it). We conduct a series of empirical investigations by using a longitudinal dataset of OSS projects hosted in GitHub, along with a survey and qualitative data. We find that followership can affect code reuse, but the effect depends on the nature of the follower (developer or observer). Overall, our study suggests that followership is important for code reuse in OSS because it enables participants to learn, and learning promotes code reuse.","2019-12","2025-04-25 15:30:54","2025-04-25 15:30:54","","1303+","","4","43","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

More specifically, the software bug fixing process of OSS can be considered to show effects of the long-term operation and/or periodicity due to the multiple version-up procedures, in addition to the common reliability growth phenomenon observed in the relatively short-term software testing. In this article we propose a stochastic point process approach to represent the long-term effect and the periodicity effect of OSS with the actual OSS bug fixing data.

In SRGM, the degree of reliability growth may fluctuate greatly according to change in the internal state of the software. It is called the change point (CP). Several researchers proposed the SRGM considering CP. In the open source software (OSS), there are many projects that continue development even after the software is released. Therefore, major updates with breaking changes may occur in it. The major updates can be a factor that causes a CP because it greatly changes the internal state of the OSS. This paper focuses on the relationship between CP and software updates. We collect OSS fault data from a bug tracking system. Moreover, we examine the behavior of SRGM before and after software updates. Furthermore, we discuss the applicability of SRGM for CP in OSS. Also, we compare the proposed model based on CP with the model without CP. As a result, we have confirmed that the SRGM can evaluate the reliability in the environment with major updates. Moreover, the proposed method performs better than without considering CP model. Especially, the exponential model's mean value function is the suitable method to assess the OSS reliability for the proposed method.","2024-08","2025-04-25 15:30:54","2025-04-25 15:30:54","","","","04","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This end-to-end scheme combines multiple state-of-the-art techniques and provides an easy-to-use software package for real-time 3D model reconstruction and offline texture mapping. The main innovation lies in various Structure-from-Motion (SfM) techniques that are used with additional depth data to yield high-quality 3D models in real-time and at low cost. The functionality of Open3DGen has been validated on AMD Ryzen 3900X CPU and Nvidia GTX1080 GPU.

However, in a research context it would often be useful to be able to modify this code and/or to have full control over all these parameters from researcher-written software. In the case of the STAR Cryoelectronics PCI/PFL family of SQUID control electronics, the supplied software contains modules for automatic tuning and noise characterization, but does not provide an interface for user code. On the other hand, the Magnicon SQUIDViewer software package includes a public application programming interface, but lacks auto-tuning and noise characterization features. To overcome these and other limitations, we are developing an “open-source” framework for controlling SQUID electronics, which should provide maximal interoperability with user software, a unified user interface for electronics from different manufacturers, and a flexible platform for the rapid development of customized SQUID auto-tuning and other advanced features.

Using a conventional protocol to fabricate IHS from casts of the initial situation or the wax-up can be challenging, time-consuming, and sometimes frustrating. A digital workflow makes this process quicker and more convenient. The IHS must be first designed with computer-aided design (CAD), then fabricated with computer-aided manufacture (CAM). Proprietary dental software is commonly used for the design process but needs to be purchased. Objective: To describe a step-by-step technique for designing an IHS for posterior relining with open-source software. Methods: This paper describes a straightforward procedure to design an IHS from a dental scan of the initial situation or a digital wax-up for an esthetic and functional temporary rehabilitation. Results: An IHS can be quickly designed using open-source software by copying an existing restoration or a conventional or digital wax-up. Then, the design can be 3D printed using a biocompatible resin. Conclusions: The clinician can use open-source software to design IHSs, which are then 3D printed using a biocompatible resin. Clinical relevance: The clinician can design IHSs from a dental scan of the initial situation or a wax-up using opensource software by following the step-by-step protocol outlined in this paper.

We developed the snow parameter processing software GiRsnow, based on GNSS-IR tools and a MATLAB environment, to obtain robust and effective retrievals.

For every type of application, there are a wide variety of alternatives. We observed that even if different applications that perform similar tasks and compiled with the same versions of the compiler and the libraries, they perform very differently while running on the same system. Sadly prior work in this area that compares two code bases for similarities does not help us in finding the reasons for the differences in performance. In this paper, we develop a tool, SoftMon, that can compare the codebases of two separate applications and pinpoint the exact set of functions that are disproportionately responsible for differences in performance. Our tool uses machine learning and NLP techniques to analyze why a given open-source application has a lower performance as compared to its peers, design bespoke applications that can incorporate specific innovations (identified by SoftMon) in competing applications, and diagnose performance bugs. In this paper, we compare a wide variety of large open-source programs such as image editors, audio players, text editors, PDF readers, mail clients and even full-fledged operating systems (OSs). In all cases, our tool was able to pinpoint a set of at the most 10-15 functions that are responsible for the differences within 200 seconds. A subsequent manual analysis assisted by our graph visualization engine helps us find the reasons. We were able to validate most of the reasons by correlating them with subsequent observations made by developers or from existing technical literature. The manual phase of our analysis is limited to 30 minutes (tested with human subjects).","2020","2025-04-25 15:30:55","2025-04-25 15:30:55","","397-408","","","","","","","IEEE International Working Conference on Mining Software Repositories","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; Korean Inst Informat Scientists & Engineers","","","","","","","","","ISSN: 2160-1852","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This phenomenon has been studied extensively, including multiple numerical models that have been formulated to predict the density distribution and its evolution in several bone types. However, despite these models, bone remodeling mechanism under different stimuli is still not well understood. We implemented a recently proposed electromechanically driven bone remodeling model that encompasses both mechanical and therapeutic electrical stimuli using an open-source software framework, and studied a two-dimensional (2D) plate model and a femur bone model, respectively. For discretization, we employed the finite element method (FEM) for the spatial quantities and Euler scheme for the time derivatives. The simulation results demonstrate that the density distribution is changed under electrical stimulation, generally resulting in a greater mass deposition. This study supports the possibility of enhancing and accelerating the bone remodeling process via simultaneous application of electrical and mechanical stimulus.","2019","2025-04-25 15:30:55","2025-04-25 15:30:55","","6466-6471","","","","","","","IEEE Engineering in Medicine and Biology Society Conference Proceedings","","","","","","","","","","","","","ISSN: 1557-170X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Organizations are also now adopting open source software, despite some reservations in particular regarding the provision and availability of support. One of the greatest concerns about free and open source software is the availability of post release support and the handling of for support. A common belief is that there is no appropriate support available for this class of software, while an alternative argument is that due to the active involvement of Internet users in online forums, there is in fact a large resource available that communicates and manages the management of support requests. The research model of this empirical investigation establishes and studies the relationship between open source software support requests and online public forums. The results of this empirical study provide evidence about the realities of support that is present in open source software projects.

This model is a liquid-solid mixture model inspired from the pioneer work of Bennon and Incropera, including mass, momentum, energy and species conservation equations. In particular, the energy conservation equation is formulated with the temperature variable, the thermosolutal convection is accounted for through the Boussinesq approximation and the interdendritic flow in the mushy zone is governed by the Darcy's law. Furthermore, a rigid solid phase is assumed and classical microsegregation models are used featuring lever-rule or Gulliver-Scheil assumptions. At the discrete level, a first-order upwind scheme is implemented with a SIMPLEC approach to solve the velocity-pressure coupling. The other couplings involving temperature and concentration fields are efficiently solved performing sub-loops with a PISO-like approach. The overall scheme is mainly implicit with additional treatments to ensure the equilibrium between the hydrostatic pressure gradient and the buoyant forces, and to deal properly with solid zones. The segregation predictions offered by the model are validated against both academic test case and industrial ingot configurations. A convergence study is also led focusing on time step and mesh size sensitivities.","2020","2025-04-25 15:30:55","2025-04-25 15:30:55","","","","","861","","","","IOP Conference Series-Materials Science and Engineering","","","","","","","","","","","","","ISSN: 1757-8981","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We briefly discuss the main principles behind the new software, its architecture, and directions for its further development. The use of the software is illustrated by examples of a turbine blade. In the first example, the turbine blade is reconstructed automatically from a structured point cloud. Another example is the interactive reconstruction of the turbine blade from an unstructured surface triangulation. In both the cases, we use a surface skinning strategy enhanced by a curve fairing operator. We show that the modified skinning operator does not minimize the total bending energy of the surface, but yields a smooth patch where input inaccuracies are compensated for. The reconstruction result is a parametric model of the turbine blade where the design variables are the coordinates of the poles for each profile curve. The proposed software architecture can be used for partial or complete parameterization of reconstructed CAD models with the aim of their subsequent optimization.","2019-07","2025-04-25 15:30:55","2025-04-25 15:30:55","","202-212","","4","45","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Specifically, our MATLAB application, ReflectSim, employs an adapted transfer matrix method simulation and can account for the effects of several critical material design parameters, including interfacial roughness and layer geometry, to determine the reflectance spectrum of user-defined 1D-PCs. By packing our codes into a graphical user interface, this software is simple to use and bypass the requirement of any coding experiences from users, which can be widely used as an education tool in high school/undergraduate classrooms and K-12 outreach activities.

Therefore, the IETF has started the development of HTTP 2.0, which is based on Google's SPDY proposal and already supported by several major companies, e. g., Facebook, Twitter, Akamai, Mozilla and obviously Google. Furthermore, Content Centric Networking (CCN) is another novel approach for future networks that is considered as an revolutionary approach compared to HTTP 2.0. The CCN communication paradigm is completely different and does not rely on direct connections between hosts, it rather focuses on the content.

A hidden Markov model (HMM) is proposed that allows us to investigate (1) the extent to which individuals learn from their own experience and from interactions with peers, (2) whether an individual's ability to learn from these activities varies as she evolves/learns over time, and (3) to what extent individual learning persists over time. We calibrate the model based on six years of detailed data collected from 251 developers working on 25 OSS projects hosted at Sourceforge. Using the HMM, three latent learning states (high, medium, and low) are identified, and the marginal impact of learning activities on moving the developer between these states is estimated. Our findings reveal different patterns of learning in different learning states. Learning from peers appears to be the most important source of learning for developers across the three states. Developers in the medium learning state benefit the most through discussions that they initiate. On the other hand, developers in the low and the high states benefit the most by participating in discussions started by others. While in the low state, developers depend entirely upon their peers to learn, whereas in the medium or high state, they can also draw upon their own experiences. Explanations for these varying impacts of learning activities on the transitions of developers between the three learning states are provided. The HMM is shown to outperform the classical learning curve model. The HMM modeling of this study contributes to the development of a theoretically grounded understanding of learning behavior of individuals. Such a theory and associated findings have important managerial and operational implications for devising interventions to promote learning in a variety of settings.","2011-12","2025-04-25 15:30:56","2025-04-25 15:30:56","","790-807","","4","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The techniques for performing inspections have been well studied in industry; in OSS development, peer reviews are less well understood. We examine the two peer review techniques used by the successful, mature Apache server project: review-then-commit and commit-then-review. Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects. We provide a comparison of the two Apache review techniques as well as a comparison of Apache review to inspection in an industrial project. We conclude that Apache reviews can be described as (1) early, frequent reviews (2) of small, independent, complete contributions (3) conducted asynchronously by a potentially large, but actually small, group of self-selected experts (4) leading to an efficient and effective peer review technique.","2008","2025-04-25 15:30:56","2025-04-25 15:30:56","","541-550","","","","","","","","","","","ACM SIGSOFT; IEEE CSE; Univ Paderborn; Univ Leipzig; SIEMENS; Zuhlke; Adesso; Deutsch Telekom Labs; sd&m; Werum; Microsoft Res; IBM; i nemis; dSPACE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In accordance with such a penetration of the Internet, it is increasing public awareness of the importance of online real-time and interactive functions. Therefore, software development environment has been changing into new development paradigms such as concurrent distributed development environment and the so-called open source project by using network computing technologies. Especially, such OSS (Open Source Software) systems which serve as key components of critical infrastructures in our society are still ever-expanding now. In this paper, we propose a software reliability growth model based on stochastic differential equations in order to consider the active state of the open source project. Especially, we assume that the software failure intensity depends on the time, and the software fault-report phenomena on the bug tracking system keep an irregular state. Also, we analyze actual software fault count data to show numerical examples of software reliability assessment for the OSS. Moreover, we compare our model with the conventional model based on stochastic differential equations in terms of goodness-of-fit for actual data.

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use Of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are also likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization, that naturally fix themselves during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-25 15:30:56","2025-04-25 15:30:56","","97-106","","","","","","","","","","","IEEE Comp Soc, Tech Comm Fault Tolerant Comp; IFIP Working Grp 10 4 Dependable Comp & Fault Tolerance; AT&T; Lucent Technologies; Compaq Comp Corp; Georgia Inst Technol; IBM Corp; LAAS CNRS; Microsoft Corp","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Results of isolated simulations may be not accurate enough on the system level. Free and open available tools like GridLAB-D, PSAT, OpenModelica and 4DIAC are well known and widely used because of their excellent domain specific expertise. With co-simulation approaches the individual strengths of each tool can be exploited to model and simulate the various aspects of complex smart grids. The achieved level of detail and realism potentially surpasses the results that the individual analyses would gain. This paper demonstrates a local smart charging control strategy implemented with the IEC 61499-based standard for distributed control systems. It is simulated with different electric vehicle driving patterns, modeled with the multi-agent environment GridLAB-D. Battery models are defined in OpenModelica and embedded as individual dynamic loads. The power system is simulated using PSAT.

Direct measurements of turbulent fluxes are very challenging and sparse, and do not span the full range of environmental conditions that exist over the ocean. This means that empirical “bulk formulae” parameterizations that relate direct flux observations to concurrent measurements of the mean meteorological and sea surface variables contain considerable uncertainty. In this paper, we present a Python 3.6 (or higher) open-source software package “AirSeaFluxCode” for the computation of the heat (latent and sensible) and momentum fluxes. Ten different parameterizations are included, each based on published descriptions or code and each derived from a different set of observations, or different assumptions about the turbulent exchange processes. They represent a range of current expert opinion on how the fluxes depend on mean properties and can be used to explore uncertainty in calculated fluxes. AirSeaFluxCode also allows the adjustment of the mean meteorological input parameters (air temperature, humidity and wind speed) from the height at which they are obtained to a user-defined output height. This height adjustment enables the comparison of measurements, or model-derived values, made at different heights above sea-level. The parameterizations calculate the fluxes using input parameters that are relatively easily to measure, or are available as model output: wind speed, air temperature, sea surface temperature, atmospheric pressure and humidity. Where original code is available we have compared its output with that of AirSeaFluxCode. Any changes made to increase consistency across algorithms by standardizing computational methods or calculation of meteorological variables, for example, are discussed and the impacts quantified: these are shown to be insignificant except for a few cases where conditions were extreme, and AirSeaFluxCode is shown to be robust. We also investigate the impact on the fluxes caused by different assumptions about the exchange processes, or the choices inherent in the implementation of the parameterizations. For example, sea surface temperature usually refers to data typically obtained at depths of between 1 and 10 m. However, since some parameterizations require a “skin” sea surface temperature, code that adjusts temperature at depth to skin temperature is included: this has a very significant impact on the fluxes. Selecting a parameterization that is appropriate for the available sea surface temperature will avoid the need to adjust the sea temperature data and the uncertainties associated with that adjustment, and will also avoid the biases due to use of the “wrong” measure of temperature. Significant differences also resulted from assumptions about the size of reduction in sea surface humidity to account for salinity effects: the uncertainty in the reduction factor needs to be quantified in future analyses. Fluxes in extreme conditions are particularly uncertain since the transfer coefficients in the different parameterizations vary most at very high and very low wind speeds. Low wind speeds are also challenging for numerical implementation since choices have to be made regarding: convergence criteria for the iterative calculation, inclusion of a parameterization for convective gustiness, or application of ad hoc limits to various parameters. All of these choices can significantly affect the flux estimates for light winds.","2023-02-06","2025-04-25 15:30:56","2025-04-25 15:30:56","","","","","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As nations increasingly rely on knowledge assets to grow, the adoption of OSS will have profound economic consequences. This paper identifies the mechanisms inherent to OSS production that help fuel innovation in knowledge-based economies. As a collaborative and open production model, OSS is conceptualized as a prototype of open innovation. Drawing on US employment projections for 2008-2018, the authors' analysis predicts OSS will have a positive impact on employment growth in well-paid salary jobs across multiple sectors of the US economy. OSS-related software development jobs are widely diffuse throughout the economy, help build a skilled labour force and offer wages significantly above the national average. OSS is thus believed to be a strong contributor to growth in high-value employment in the US. The authors also posit that, as industries are exposed to the benefits of OSS as a result of the broad diffusion of OSS-related jobs, open innovation processes outside software development may be adopted through a process of learning and imitation.","2015","2025-04-25 15:30:56","2025-04-25 15:30:56","","528-560","","","","","","","","","","","","","","","","","","","","DOI: 10.4018/978-1-4666-7230-7.ch029","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of FOSS (Free and Open Source Software) systems, many upgrade errors cannot be discovered by current upgrade managers and then a system upgrade can potentially lead the system to an inconsistent and incoherent state. Objective: The objective of this paper is to propose an approach to simulate the upgrade of complex systems in order to predict errors before they affect the real system. Method: The approach promotes the use of model-driven engineering techniques to simulate the upgrade of complex systems. The basic idea is to have a model-based description of the system to be upgraded and to make use of model transformations to perform the upgrade on a source model so to obtain a target model representing the state of the upgraded system. Results: We provide an implementation of the simulator, which is tailored to FOSS systems. The architecture of the simulator is distribution independent so that it can be easily instantiated to specific distributions. The simulator takes into account also pre and post-installation scripts that equip each distribution package. This feature is extremely important since maintainer scripts are full-fledged programs that are run with system administration rights. Conclusions: The paper shows the kind of errors the simulator is able to predict before upgrading the real system, and how the approach improves the state of the art of package managers while integrated in real Linux distribution installations.

Currently coupled computations solve the same governing equations using different coupling methods, which can be sorted into two categories: loose coupling and tight coupling. This paper proposes and verifies a third coupling approach called “the Integrated Tight Coupling (ITC) method”. The mathematical equations in the nuclear fuel are rearranged to be integrated via a novel concept of the energy-group function. In addition, the data from the neutron cross section library can be used directly. The ITC method is implemented using two open-source codes: the DRAGON code and OpenFOAM. Additionally, a coupled computation using these two codes is new and has not been done. The ITC method is verified using a 1.5-D (1-D neutronics and 2-D thermal-hydraulics) symmetric unit cell example. The mesh of the tightly integrated computation is 25% coarser than the loosely coupled one. Starting from a similar initial guess, the number of iterations for the ITC method is 24% fewer than that for the loosely coupled computation to reach the same accuracy.

With further improvement and additional testing, the ITC method has the potential to be incorporated with other neutronics and thermal-hydraulics codes. (C) 2015 Elsevier Ltd.

An abundant amount of effort has been put by the research community to develop software maintainability prediction (SMP) models by relating software metrics to the maintainability of modules or classes. When software classes demanding the high maintainability effort (HME) are less as compared to the low maintainability effort (LME) classes, the situation leads to imbalanced datasets for training the SMP models. The imbalanced class distribution in SMP datasets could be a dilemma for various ML techniques because, in the case of an imbalanced dataset, minority class instances are either misclassified by the ML techniques or get discarded as noise. The recent development in predictive modeling has ascertained that ensemble techniques can boost the performance of ML techniques by collating their predictions. Ensembles themselves do not solve the class-imbalance problem much. However, aggregation of ensemble techniques with the certain techniques to handle class-imbalance problem (e.g., data resampling) has led to several proposals in research. This paper evaluates the performance of ensembles for the class-imbalance in the domain of SMP. The ensembles for class-imbalance problem (ECIP) are the modification of ensembles which pre-process the imbalanced data using data resampling before the learning process. This study experimentally compares the performance of several ECIP using performance metrics Balance and g-Mean over eight Apache software datasets. The results of the study advocate that for imbalanced datasets, ECIP improves the performance of SMP models as compared to classic ensembles.","2020-10","2025-04-25 15:30:57","2025-04-25 15:30:57","","","","5, SI","27","","","","","","","","","","","","","","","","","Publisher: Univ Delhi, Dept Operat Res; Soc Reliabil Engn Qual & Operat Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thus, today's professional OSS projects receive contributions from hobbyists, universities, research centers, as well as software vendors and user firms. Theorists have referred to this kind of combined public and private investments in innovation creation as private-collective innovation. In particular, the private-collective innovation model seeks to explain why firms privately invest resources to create artifacts that share the characteristics of non-rivalry and non-excludability. The aim of this research is to investigate how different contributor groups associated with public and increasing private interests interact in an OSS development project. The results of the study show that the balance between private and collective contributors in the Linux kernel development seems to be changing to an open source project that is mostly developed jointly by private companies.","2015","2025-04-25 15:30:57","2025-04-25 15:30:57","","299-313","","","9373","","","","Lecture Notes in Computer Science","","","","IFIP Working Grp 6 11","","","","","","","","","ISSN: 0302-9743","","","","","","Janssen, M; Mantymaki, M; Hidders, J; Klievink, B; Lamersdorf, W; VanLoenen, B; Zuiderwijk, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Business process management is intended to implement efficient and customer orientated processes whereby the simulation of business processes can be used to evaluate the quality of processes and to identify areas of improvements. Since real business processes usually contain decision processes which can be solved by optimization systems, it makes sense to,combine the simulation and the optimization of business processes. (Marz et.al. 2010, p 3ff.) As an example of a reasonable combined simulation and optimization of business processes, the navigation in a road network is discussed in this paper. Consider vehicles seeking the fastest route from a starting node to a target node using a navigation system. The amount of time spent driving on an arc is influenced by the distance and the amount of the vehicles on this arc and is continuously changing. The structure of the road network and the traffic within the network is described in a simulation model while the fastest path decisions of each vehicle are made by using an optimization system. There is obviously a relationship between the individual decisions made for each of the vehicles and the state of the entire network. The aim of this paper is to describe how a combined simulation and optimization of business processes can be created through using EPC-Simulator (Muller 2012) as a simulation system and CMPL (Steglich and Schleiff 2010) as an optimization system where the network traffic simulation is used exemplarily.","2013","2025-04-25 15:30:57","2025-04-25 15:30:57","","808+","","","","","","","","","","","European Council Modelling & Simulat; Aalesund Univ Coll; Res Council Norway; More & Romsdal Cty Municipal; Rolls Royce Marine; Offshore Simulator Ctr AS; Farstad Shipp; Sparebanken More; Tekna; Norwegian Maritime Competence Ctr","","","","","","","","","","","","","","","Rekdalsbakken, W; Bye, RT; Zhang, H","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While already being used for clinical application, the complex interplay between these parameters requires thorough validation via simulations. These simulations required a realistic, controlled and adaptable model of the white matter axons with the surrounding myelin sheath. While there already exist useful algorithms to perform this task, none of them combine optimisation of axon packing, presence of myelin sheath and availability as free and open source software. Here, we introduce a novel disk packing algorithm that addresses these issues. The performance of the algorithm is tested in term of reproducibility over 50 runs, resulting density, and stability over iterations. This tool was then used to derive multiple values of FVF and to study the impact of this parameter on fr and MVF in light of the known microstructure based on histology sample. The standard deviation of the axon density over runs was lower than 10(-3) and the expected hexagonal packing for monodisperse disks was obtained with a density close to the optimal density (obtained: 0.892, theoretical: 0.907). Using an FVF ranging within [0.58, 0.82] and a mean inter-axon gap ranging within [0.1, 1.1] mu m, MVF ranged within [0.32, 0.44] and fr ranged within [0.39, 0.71], which is consistent with the histology. The proposed algorithm is implemented in the open-source software AxonPacking (hups://github.comineuropoly/ axonpacking) and can be useful for validating diffusion models as well as for enabling researchers to study the interplay between microstructure parameters when evaluating qMRI methods.","2017-01-31","2025-04-25 15:30:57","2025-04-25 15:30:57","","","","","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It has been suggested that such small-scale and home-grown solutions (e.g. mobile phone apps), usually championed by social enterprises (SEs), are more likely to introduce pro-poor change than infrastructure heavy ICT initiatives designed by state and other international actors. In the Indian context, FOSS-based social innovations (SIs) introduced by SEs are helping poor communities tackle previously thought-to-be unresolvable socio-economic problems. An interesting question, therefore, would be: in what ways is the SE model and approach uniquely equipped to develop FOSS-based SIs that deliver pro-poor change? The empirical component of the research attempts to shed light on this question by uncovering the nuts and bolts of the development methodology deployed by an SE during the coding and launch of an FOSS-based SI. Findings highlight the significant role of the founder's social vision; the challenges of accurately capturing and translating to software developers the nature and nuance of social problems; and, the incumbent issues in putting together a methodology that creates active user engagement throughout the software development process, overcoming difficult barriers such as language and culture.

However, these infrequent volunteers contribute to the sustainability of FLOSS projects, and should ideally be encouraged to continue participating, even if they cannot be persuaded to contribute regularly. Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature. Also, episodic volunteers make a wide range of value-added contributions other than code, and they should neither be expected nor coerced into becoming habitual volunteers.","2020-09-01","2025-04-25 15:30:57","2025-04-25 15:30:57","","962-980","","9","46","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The controller plays the role of the `brain' that dictates the intelligent part of SDN technology. Various versions of SDN controllers exist as a response to the diverse demands and functions expected of them. There are several SDN controllers available in the open market besides a large number of commercial controllers; some are developed to meet carrier-grade service levels and one of the recent trends in open-source SDN controllers is the Open Network Operating System (ONOS). This paper presents a comparative study between open source SDN controllers, which are known as Network Controller Platform (NOX), Python-based Network Controller (POX), component-based SDN framework (Ryu), Java-based OpenFlow controller (Floodlight), OpenDayLight (ODL) and ONOS. The discussion is further extended into ONOS architecture, as well as, the evolution of ONOS controllers. This article will review use cases based on ONOS controllers in several application deployments. Moreover, the opportunities and challenges of open source SDN controllers will be discussed, exploring carrier- grade ONOS for future real-world deployments, ONOS unique features and identifying the suitable choice of SDN controller for service providers. In addition, we attempt to provide answers to several critical questions relating to the implications of the open-source nature of SDN controllers regarding vendor lock-in, interoperability, and standards compliance, Similarly, real-world use cases of organizations using open-source SDN are highlighted and how the open-source community contributes to the development of SDN controllers. Furthermore, challenges faced by open-source projects, and considerations when choosing an open-source SDN controller are underscored. Then the role of Artificial Intelligence (AI) and Machine Learning (ML) in the evolution of open-source SDN controllers in light of recent research is indicated. In addition, the challenges and limitations associated with deploying open-source SDN controllers in production networks, how can they be mitigated, and finally how open- source SDN controllers handle network security and ensure that network configurations and policies are robust and resilient are presented. Potential opportunities and challenges for future Open SDN deployment are outlined to conclude the article.","2024","2025-04-25 15:30:58","2025-04-25 15:30:58","","747-800","","1","80","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We used procedures of Grounded Theory-open and axial coding-to analyze the data. We found that newcomers are not confident enough to choose their initial task and they need information about the tasks or direction from the community to support choosing a task more suitable for them.

For laboratory lectures, we need a tool that is complete and easy to use. In this work we present a Java library which is oriented to teaching. This means that we have designed and built the library thinking in readability and understanding instead of efficiency. In this paper we present the open source project JavaVis, oriented to Computer Vision teaching. It consists of a framework with several features that make it useful for that purpose. It was designed to be easy to use: the user does not have to deal with internal structures and graphical interface, and adding a new algorithm is a simple task. We have developed three different modules, based on three different needs we have noticed in our subjects. The first one is a basic library for image processing. Besides the previously commented features, it supports geometrical data (edges, segments, points, etc.). The second module is based on the same working schema as the first one, but applied to 3D data. These two modules are enough for testing many well-known algorithms. They also suit the programming needs of students and teachers, as they can easily develop their own algorithms for the JavaVis framework. All JavaVis functions can be launched both from command line, as well as with the JavaVis Graphical User Interface. Finally we have extended JavaVis with a third module consisting of a visual desktop where different Computer Vision functions can be easily placed and connected.

Different persons provide diverse know-how about modeling and simulating engineering and/or business problems, about search and optimization methods, and about new software trends to implement them into software. This paper describes the approach how an optimization framework based on evolutionary algorithms and other methods is developed in subsequent projects with application engineers and software developers cooperatively working together guaranteeing a sophisticated knowledge transfer. Therefore, particular knowledge management aspects are emphasized. As result, the optimization platform OpenOpal and the ideas behind its software architecture, supporting the know-how transfer, are presented. In order to continuously improve this optimization framework it is transferred into an open-source software initiative. The objective is to broaden the user group by increasing the number of knowledge contributors both from academia - integrating and testing newly developed optimization methods - and from various engineering areas - providing real-world problems to be solved.","2010","2025-04-25 15:30:58","2025-04-25 15:30:58","","","","","","","","","IEEE Congress on Evolutionary Computation","","","","IEEE; IEEE Computat Intelligence Soc; Int Neural Network Soc; Evolut Program Soc; IET","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The governing equations underlying MASCARET are the shallow water equations for unsteady flow propagation and the advection-dispersion equation for water quality and contaminant transport. The hydraulic component accounts for floodplains and storage areas, and flow at channel junction can be treated using a 2-D approach. Additionally, flood propagation over dry beds (e. g. dam-break flows) and non-hydrostatic waves can be simulated. The user interface FUDAA-MASCARET manages the input data, allocation of parameters, running of simulations and viewing outputs. MASCARET can be easily compiled as a dynamic library, offering special interfaces to be used with three main steps: Initialization, Run and Finalization of the calculation. With these features, MASCARET can be coupled or integrated to other softwares without requiring significant efforts. Since July 2011, MASCARET is worldwide distributed as an open-source code. In this paper, are presented various applications of this tool covering both flow hydrodynamic and water quality. Model-data comparisons show the performance of the modeling framework, and demonstrate the interest of this open-source software for the scientific community.","2012","2025-04-25 15:30:58","2025-04-25 15:30:58","","1169-1174","","","","","","","","","","","Colegio Ingenieros Civiles Costa Rica; Int Assoc Hydro Environm Engn & Res, Comm Fluvial Hydraul","","","","","","","","","","","","","","","Munoz, RM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The increased participation is an observable phenomenon; many researchers and practitioners assume that the practice of community sharing does not improve the bottom line, but rather believe the practice is altruistic in nature. Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, Why do for-profit corporations participate in the development of open source software? was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory. In this article, we examine interview responses and field study data from corporate members of open source communities to determine how they justify devoting time and effort to community engagement. Our study makes a contribution to open source software literature by revealing that numerous rational and emotional reasons exist for corporate participation in open source software development.","2016","2025-04-25 15:30:58","2025-04-25 15:30:58","","323-343","","4","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They use various technologies to create solutions that boost and advance healthcare systems and healthcare delivery. Open-source software (OSS) technology has become an essential component of startups' toolkits, providing various advantages, such as free access to source codes and opportunities for innovation. Research on OSS in healthcare startups is limited, so our study aims to investigate how healthtech startups perceive the influence of OSS on product development and to identify the challenges they face. To meet this objective, we conducted an empirical study with six health-tech startups, using semi-structured interviews. Thematic analysiswas performed on the collected data to identify common themes and subthemes related to the research objective. The findings showed that health-tech startups benefit from the cost efficiency, scalability, and customization of OSS. Open-source software tools, reshape development and promote efficient code management, provide community support, and reduce costs. However, they demand OSS knowledge, management of updates, regulatory compliance, and heightened cybersecurity. Our study adds to the body of knowledge on OSS and healthcare startups and the connection between them. We provide recommendations for health-tech startups, such as embracing OSS tools for their benefits, investing in education and training, and engaging with the OSS community for comprehensive support in their product development processes.","2024","2025-04-25 15:30:58","2025-04-25 15:30:58","","265-282","","","500","","","","Lecture Notes in Business Information Processing","","","","","","","","","","","","","ISSN: 1865-1348","","","","","","Hyrynsalmi, S; Munch, J; Smolander, K; Melegati, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The gains obtained from the reuse of community-developed libraries may be offset by the cost of detecting, assessing, and mitigating their vulnerabilities in a timely manner. In this paper we present a novel method to detect, assess and mitigate OSS vulnerabilities that improves on state-of-the-art approaches, which commonly depend on metadata to identify vulnerable OSS dependencies. Our solution instead is code-centric and combines static and dynamic analysis to determine the reachability of the vulnerable portion of libraries used (directly or transitively) by an application. Taking this usage into account, our approach then supports developers in choosing among the existing non-vulnerable library versions. Vulas, the tool implementing our code-centric and usage-based approach, is officially recommended by SAP to scan its Java software, and has been successfully used to perform more than 250000 scans of about 500 applications since December 2016.

For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.","2010","2025-04-25 15:30:58","2025-04-25 15:30:58","","","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, much of the academic research on OSS has focused on individual rather than organizational issues. Hence while there is some understanding of why individual developers and users opt for particular OSS applications, relatively little is known about the adoption of OSS as a software acquisition policy. This paper presents a study of 13 managers in the secondary software sector in Europe, and examines how their perceptions of the benefits and drawbacks of OSS affected their decision to adopt an open source policy for software in their companies. The study reveals how their perceptions of the business and technical benefits and drawbacks of OSS influenced the technological, organizational, environmental and individual factors considered within the adoption process. The findings reveal that many of these factors are similar to those reported by previous work on the adoption of innovation, leading us to conclude that organizational processes for the adoption of open innovation are reliant on the practices for closed innovation despite frequently cited loss of organizational control associated with open innovation.","2010-02","2025-04-25 15:30:59","2025-04-25 15:30:59","","76-95","","1","41","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

When the measurement data is assumed to be obtained on a uniform grid which is staggered with respect to the discretization of the parameter volume, the resulting kernel sensitivity matrices exhibit block-Toeplitz-Toeplitzblock (BTTB) structure. These matrices are symmetric for the gravity problem but unsymmetric for the magnetic problem. In each case, the structure facilitates fast forward computation using two-dimensional fast Fourier transforms. The construction of the kernel matrices and the application of the transform for fast forward multiplication, for each problem, is carefully described. But, for purposes of comparison with the non-transform approach, the generation of the unique entries that define a given kernel matrix is also explained. It is also demonstrated how the matrices, and hence transforms, are adjusted when padding around the volume domain is introduced. The transform algorithms for fast forward matrix multiplication with the sensitivity matrix and its transpose, without the direct construction of the relevant matrices, are presented. Numerical experiments demonstrate the significant reduction in computation time and memory requirements that are achieved using the transform implementation. Thus, it becomes feasible, both in terms of reduced memory requirements and computational time, to implement the transform algorithms for large three-dimensional volumes. All presented algorithms, including with variable padding, are coded for optimal memory, storage and computation as an open source MATLAB code which can be adapted for any convolution kernel which generates a BTTB matrix, whether or not it is symmetric. This work, therefore, provides a general tool for the efficient simulation of gravity and magnetic field data, as well as any formulation which admits a sensitivity matrix with the required structure.","2020-11","2025-04-25 15:30:59","2025-04-25 15:30:59","","","","","144","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The scientific literature presents several techniques that can be used to recognize the user's emotional state. However, many techniques involve the use of sensors that can result in financial costs and cause discomfort to the user. In this scenario, the recognition of the emotional state through the analysis of facial expressions presents itself as a useful and practical approach, since it does not involve the use of sensors attached to the user's body and executed in different types of devices. Despite these advantages, software that allow the analysis of facial expressions for free are still incipient, and performance evaluation of this type of software usually is not available. In order to contribute to this context and assist researchers who need this type of software, this study presents a comparative analysis of two open-source emotion recognition software (”CLMTrackr” and “Face-api.js”) simulating different environmental conditions related to lighting and distance. Considering images from two datasets, we generate 8675 videos simulating 25 different environmental conditions.

Greenhouse environment parameters measured were air temperature, relative humidity, and carbon dioxide (CO2) concentration. The ranges of the temperature, relative humidity, and CO2 concentration were -40 to 120 degrees C, 0 to 100%, and 0 to 10,000 ppm, respectively. A 128 x 64 graphic LCD display was used for real-time monitoring of the greenhouse environments. An Arduino Uno R3 consisted of a USB interface for communicating with a computer, 6 analog inputs, and 14 digital input/output pins. A temperature/relative humidity sensor was connected to digital pins 2 and 3. A CO2 sensor was connected to digital pins 12 and 13. The LCD was connected to digital pin 1 (TX). The sketches were programmed with the Arduino Software (IDE). A measurement system including the Arduino board, sensors, and accessories was developed (totaling $244).

Free open source software projects generally have one mailing list for developers and another one for users. This large number of mailing lists changes constantly and shows a great variety with respect to membership and topics covered. This makes them very difficult to monitor. One way of overcoming this Big Data Challenge is to identify some easily computable global indicators that can be used for instance to detect important events. We illustrate this approach here by making a social network analysis and comparison of developers' and users' mailing lists of four free open source software projects: CentOS, GnuPG, Mailman and Samba. We show that these mailing lists have some common characteristics : the number of messages, the time durations and the interlink times can be fitted using power and lognormal laws with suitable scales and parameters; for the interlink time, the analysis is done using the temporal delta density inspired by the delta density introduced by Viard and Latapy. This similarity between the characteristics of mailing lists also applies to the structure of dominant groups. For the time evolution of the number of messages, GnuPG exhibits a particular behavior. The interpretation of the different parameters gives very interesting insights into the membership and the type of topics covered by the mailing lists. The analysis carried out here and similar studies cited in this paper can therefore be considered as a first step towards the designing of building blocks for monitoring mailing lists.","2015","2025-04-25 15:30:59","2025-04-25 15:30:59","","728-732","","","","","","","IEEE International Congress on Big Data","","","","IEEE; IEEE Comp Soc; Serv Comp; Serv Soc; Comp Cloud; Serv Comp; BIG Data; Hp; IBM; ERICSSON; SAP; IBM Res; HUAWEI; OMG Object Management Grp; IEEE Cloud Comp; Business Proc Integrat & Management; IT Profess; Intl Journal Web Serv Res; Comp Now Access Discover Engage; IEEE Transact Serv Comp","","","","","","","","","ISSN: 2379-7703","","","","","","Barbara, C; Khan, L","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Owing to the uncertainty and complexity of OSS development, testing and debugging environments, OSS are completed dynamically. When detected faults are removed for OSS, they are likely to introduce new faults. Moreover, under the different OSS debugging environments, fault introduction will show different changes. For example, the fault introduction rate shows a decrease change, or increasing first and then decreasing change over time. Considering the complex and dynamic changes in fault introduction, an OSS reliability model that fault introduction obeys a generalized inflection S-shaped distribution is proposed in this paper. Experimental results indicate that the fitting and predictive performance of the proposed model is good. The established model in this paper can adapt the dynamical and complicated changes of fault introduction during OSS debugging. Moreover, the established model can accurately forecast the number of remaining faults in OSS, and assist developers to evaluate the actual OSS reliability.","2022-09","2025-04-25 15:30:59","2025-04-25 15:30:59","","","","9","4","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the substantive economic and efficiency-related implications of OSS adoption, there is surprisingly little research into the determinants of the diffusion of OSS across public sector jurisdictions. In this article we explore the variation in OSS adoption among Dutch local administrations. The Dutch central government adopted a policy to stimulate the use of OSS in the public sector, but the non-mandatory character of the policy resulted in great differences in the degree of adoption of OSS at the local level. Using data from a new survey of municipalities in the Netherlands and proportional odds statistical models to analyze the data, we show that the degree of OSS adoption crucially depends on the presence of boundary spanners and political commitment within the local government On the other hand, oft-suspected factors like financial stress and jurisdiction size have no discernible effects. Our findings have implications for understanding the spread of OSS in the public sector and for public policies designed to encourage OSS diffusion.

J.","PING-Mapper: Open-Source Software for Automated Benthic Imaging and Mapping Using Recreation-Grade Sonar","EARTH AND SPACE SCIENCE","","","10.1029/2022EA002469","","The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation-grade side-scan sonar systems are increasingly used to aid scientific inquiries in aquatic environments due to their relative low-cost, ease of operation, low-weight, and ease of mounting on a variety of vessels. However, existing procedures and software for post-processing these data are either limited, closed source, or fail on data from new sonar models, limiting the development of reproducible workflows. Here, we present PING-Mapper, an open-source and freely available side-scan sonar post-processing toolset for processing and mapping sonar recordings from popular Humminbird instruments. The modular software automatically: (a) decodes sonar recordings from any Humminbird system, (b) exports ping attributes from every sonar channel, (c) uses sonar sensor depth for water column removal, and (d) exports sonogram tiles and georectified mosaics. Sonar channels are processed in parallel for quick decoding and metadata extraction. Major processing wokflows, including georectification and image export, are optimized to scale with computing resources. The software has been extensively tested using data from several rivers of varying character and distribution of depths, but could also be used in estuarine and lacustrine environments. Usage of PING-Mapper is illustrated in three case studies focused on mapping large woody debris, bathymetric mapping, and visual interpretation and mapping of substrates for selected reaches of the Pearl and Pascagoula river systems in Mississippi. Plain Language Summary Side-scan sonar instruments provide a way to survey and visualize the bottom of rivers, lakes, or oceans. Since the early 2000s, companies catering predominantly to anglers have manufactured recreation-grade side-scan sonar systems to aid fishermen in locating fish and identifying potential hazards. Scientists seeking to understand and manage aquatic habitats used these systems to create grayscale images of water bottoms because they are inexpensive, easy to operate, and require minimal mounting equipment on the boat. Software has been created by companies to process these data, but the underlying processing workflow and computer code are not publicly available, making it difficult to reproduce and compare results across studies. Other publicly available approaches and software are either outdated, not maintained, or not free. That is why we made PING-Mapper, a freely available software developed in an increasingly popular programming language called Python. We designed the software to work on any computer to export the data sets quickly and efficiently. The scientific use of exported data sets is demonstrated with three case studies focused on locating and mapping targets (specifically large trees and branches), creating depth maps, and visually discerning the distributions of common substrates, such as sand and cobble.","2022-09","2025-04-25 15:30:59","2025-04-25 15:30:59","","","","9","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The proposed model quantifies the complexity in the source code using the Shannon entropy measure. In addition, the issues fixing growth behavior is viewed as a function of continuation time of the software in the field environment and amount of uncertainty or complexity present in the source code. Therefore, a two-dimensional function called Cobb-Douglas production function is applied to model the intensity function of the issues fixing rate. Furthermore, the rate of fixing the different issue types is considered variable that may alter after certain time points. Thus, this study incorporates the concept of multiple change-points to predict and assess the fixing behavior of issues in the software system. The performance of the proposed model is validated by fitting the proposed model to the actual issues data of three open-source projects. Findings of the data analysis exhibit excellent prediction and estimation capability of the model.","2020-10","2025-04-25 15:30:59","2025-04-25 15:30:59","","","","5, SI","27","","","","","","","","","","","","","","","","","Publisher: Univ Delhi, Dept Operat Res; Soc Reliabil Engn Qual & Operat Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-player game and examine how open-source licensing affects competition among an open-source originator, an open-source contributor, and a proprietor competing in an enterprise software market. In this regard, we examine (1) how quality investments and prices are endogenously determined in equilibrium, (2) how license restrictiveness impacts equilibrium investments and the quality of offerings, and (3) how license restrictiveness affects consumer surplus and social welfare. Although some in the open-source community often advocate restrictive licenses such as theGNUGeneral Public License because it is not always in the best interest of the originator for the contributor to invest greater development effort, such licensing can actually be detrimental to both consumer surplus and social welfare when it exacerbates this incentive conflict. We find such an outcome in markets characterized by software providers with similar development capabilities yet cast in favor of the proprietor. In contrast, when these capabilities either become more dispersed or remain similar but tilt in favor of open source, a more restrictive license instead encourages greater effort from the OSS contributor, leads to higher OSS quality, and provides a larger societal benefit.","2021-05","2025-04-25 15:31:00","2025-04-25 15:31:00","","3041-3066","","5","67","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By knowing this licensing effect through scientific publications and their experience, project managers became able to act strategically, loosening up the restrictions associated with their source code due to sponsor interests, for example; or the contrary, tightening restrictions up to guarantee source code openness, adhering to the “forever free” strategy. But, have project managers behaved strategically like that, changing their projects license? Up to this paper, we did not know if and what types of changes in these legal allowances project managers have made and, more importantly, whether such managerial interventions are associated with variations in intervened project attractiveness (i.e., related to their numbers of web hits, downloads and members). This paper accomplishes these two goals and demonstrates that: 1) managers of free and open source software projects do change the distribution rights of their source code through a change in the (group of) license(s) adopted; and 2) variations in attractiveness are associated with the strategic choice of a licensing schema. To reach these conclusions, a unique dataset of open source projects that have changed license was assembled in a comparative form, analyzing intervened projects over its monthly periods of different licenses. Based on a sample of more than 3500 active projects over 44 months obtained from the FLOSSmole repository of Sourceforge.net, 756 projects that had changed their source code distribution allowances and restrictions were identified and analyzed. A dataset on these projects' type of changes was assembled to enable a descriptive and exploratory analysis of the types of license interventions observed over a period of almost four years anchored on projects' attractiveness. More than 35 types of interventions were detected. The results indicate that variations in attractiveness after a license intervention are not symmetric; that is, if a change from license schema A to B is beneficial to attractiveness, a change from B to A is not necessarily prejudicial. This and other interesting findings are discussed in detail. In general, the results here reported support the current literature knowledge that the restrictions imposed by the license on the source code distribution are associated with market success vis-a-vis project attractiveness, but they also suggest that the state-of-the-science is superficial in terms of what is known about why these differences in attractiveness can be observed. The complexity of the results indicates to free software managers that no licensing schema should be seen as the right one, and its choice should be carefully made, considering project strategic goals as perceived relevant to stakeholders of the application and its production. These conclusions create awareness of several limitations of our current knowledge, which are discussed along with guidelines to understand them deeper in future research endeavors.","2017-08-07","2025-04-25 15:31:00","2025-04-25 15:31:00","","","","","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This free collaboration gathers globally distributed teams. Similarly, it is common today to view businesses and other human organisations as ecosystems, where several participating companies and organisations cooperate and compete together. As an example, Free/Libre Open Source Software ( FLOSS) development is one area where community driven development provides a plausible platform for both development of products and establishing a software ecosystem where a set of businesses contribute their own innovations. Equally, open and informal learning environments and open innovation platforms are also gaining ground. While such initiatives are not limited to any specific area, they typically offer a technological, legal, social, and economic framework for development, relying always on people as open development would not exist without the active participation of them. This paper explores the participation of master students in FLOSS projects, while merging two different settings of learning: formal and open/informal education.","2016","2025-04-25 15:31:00","2025-04-25 15:31:00","","201-206","","","","","","","Proceedings on the European Conference of e-Learning","","","","","","","","","","","","","ISSN: 2048-8637","","","","","","Novotna, J; Jancarik, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Appropriate management tools in free software, in addition to reducing the necessary investments in software, enable the development of new functionalities and also provide for local technological development. An association is made between free software and social technology, due to their mutual characteristics, in which technology is developed and shared by the community, providing autonomy and independence. The objective is to raise knowledge and application of information technology governance using free tools. To achieve this goal, a literature review on IT governance and free software was carried out, with a focus on Gestionnaire Libre de Parc Informatique (GLPI). Then, a research with exploratory-descriptive objective, qualitative-quantitative approach, with field research procedures and case study was carried out. Data were obtained through the application of a questionnaire, being the case unit the Federal Institute of Sao Paulo. It was applied as analysis method: content analysis, comparative analysis and, finally, a descriptive analysis. As a result, it was observed that governance brings the proposal of transparency in the use of technologies, human resources and actions performed in society, by society and for society. It is concluded that the results achieved can contribute to expand the knowledge about the application of information technology governance practices and the use of free software in that institution and other related institutions, improvement in the services rendered to the population.","2022-12","2025-04-25 15:31:00","2025-04-25 15:31:00","","1-17","","","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Free software communities can be considered communities of practice, since they aggregate people interested in donating and collecting, that is, sharing knowledge about free software. According to the literature, the donation and collection of knowledge are motivated by different factors and these motivations may vary depending on the context. Free software communities may include members from different countries and backgrounds, which can make keeping such communities active and vigorous a challenge. This study aims to identify the motivations for knowledge sharing behaviour that are susceptible to leadership actions in free software communities. The research was carried out in three phases. First, a qualitative study involving twenty semi-structured interviews was conducted among members of a free software community, who suggested sixteen motivations for knowledge sharing behaviour. These motivations were then organized into three groups, each with a specific focus: three motivations only influence knowledge collection and focus on the knowledge itself; nine motivations only influence knowledge donation and focus on the individual; and four motivations influence both knowledge collection and knowledge donation, and focus on the relationships among individuals. After that, based on the groups of motivation identified in the previous phase, five leaders from different communities of practice were interviewed with the aim of identifying the main motivations that would be susceptible to their actions, which were knowledge quality, ease of access to knowledge, recognition, community support for knowledge sharing, learning and professional reasons. Finally, these six main motivations indicated by the leaders were tested in a quantitative phase involving 260 members of different free software communities. The results show that learning and ease of access to knowledge influence knowledge collection; recognition, community support for knowledge sharing and knowledge collection influence knowledge donation; and professional reasons influence both knowledge collection and knowledge donation in the context of free software communities.","2015","2025-04-25 15:31:00","2025-04-25 15:31:00","","86-94","","","","","","","Proceedings of the European Conference on Knowledge Management","","","","","","","","","","","","","ISSN: 2048-8963","","","","","","Massaro, M; Garlatti, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is not until this method is examined more closely that its many advantages can be realised. The method can, however, seem very disorgamsed especially when compared with traditional proprietary development styles. A key difference between these two development approaches lies in the management of projects, and perhaps as a consequence, in the level of formality in the community environment. This paper presents the results of empirical survey research investigating FOSS community participants' views on the level of formality in FOSS, and the way in which this affects both development and support provision activities.

In this article, we propose SCGM (Software Community Graph Model), a new class of graph models to define the OSS development community. Based on the SCGM, we propose a structural analysis method of OSS development community evolution. To automate the analysis method, a prototype system is implemented with the graph DB Neo4j. We applied the proposed method and prototype system to four major machine learning OSS communities, Caffe, Chainer, Jubatus, and Tensorflow, for over five years on GitHub. From the analysis, we discovered three novel characteristics of community evolution, 1) three layered community evolution models consisting of the Core, Semi-core and Non-core members, 2) three developer growth patterns in terms of contribution behavior, and 3) evolutional changes according to the interaction among developers, which is a major contribution of this work. Based on the experiments, we demonstrate the validity and effectiveness of the proposed method.","2018","2025-04-25 15:31:00","2025-04-25 15:31:00","","292-297","","","","","","","Proceedings International Computer Software and Applications Conference","","","","IEEE Comp Soc","","","","","","","","","ISSN: 0730-3157","","","","","","Reisman, S; Ahamed, SI; Demartini, C; Conte, T; Liu, L; Claycomb, W; Nakamura, M; Tovar, E; Cimato, S; Lung, CH; Takakura, H; Yang, JJ; Akiyama, T; Zhang, Z; Hasan, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this work, we utilize the World Of Code dataset, which contains commit activity data for millions of OSS projects, to build collaboration networks for ten popular programming language ecosystems, containing in total over 290M commits across over 18M projects. We build a collaboration graph representation for each language ecosystem, having authors and projects as nodes, which enables various forms of social network analysis on the scale of language ecosystems. Moreover, we capture the information on the ecosystems' evolution by slicing each network into 30 historical snapshots. Additionally, we calculate multiple collaboration metrics that characterise the ecosystems' states. We make the resulting dataset publicly available% including the constructed graphs and the pipeline enabling the analysis of more ecosystems.","2023","2025-04-25 15:31:00","2025-04-25 15:31:00","","663-667","","","","","","","IEEE International Conference on Software Analysis Evolution and Reengineering","","","","IEEE; IEEE Comp Soc; Macau Univ Sci & Technol","","","","","","","","","ISSN: 1534-5351","","","","","","Zhang, T; Xia, X; Novielli, N","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Notwithstanding the strengths of GEs, they lack support for many common GIS file formats, and there exist only limited georeferencing possibilities. Visualizing large-scale geolocations involves high authoring costs, and the shortcomings of GEs further complicate the workflow. In this paper, we present a workflow and its implementation for creating large immersive virtual environments that accurately represent real-world urban areas. The benefits of the presented development are threefold. First, it makes the process more efficient by automating multiple steps and incorporating a large portion of the workflow inside the GE. Second, it facilitates an interactive framework by allowing the developer to efficiently extend the scene components with functionalities and interactions. Third, it entirely relies on open-source software and data, making it suitable for many non-commercial domains. To showcase the effectiveness of the tool, we created a virtual replica of an actual city consisting of the terrain, the streets, and the buildings.","2022","2025-04-25 15:31:00","2025-04-25 15:31:00","","103-114","","","","","","","VISIGRAPP","","","","","","","","","","","","","ISSN: 2184-4321","","","","","","Sousa, AA; Debattista, K; Bouatouch, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The present research aims to introduce a new architecture proposal for migrating traditional (automation) to smart (digitization) factories, implemented through open-source software. The proposed architecture is integrated, for the first time, by the interconnection of six main elements: cyber-physical systems, edge computing, artificial intelligence, cloud computing, data analytics, and cybersecurity; the research describes in detail their definitions, sub-elements, the interconnection between elements, and the minimum requirements for implementation. The test of the proposed smart factory was done through a scale smart factory pilot testing for a pick and place process, where the assembly of wood pieces from the geometric Tangram's puzzle was required; for this reason, the pilot testing includes a six-degree-of-freedom robot arm, a conveyor, a vision system, and a storage area. The case study conducted in this research allowed the assembly of four puzzles (fish, house, rocket, and swan) that were assembled with four different batches of pieces. The implementation allowed testing flexibility and adaptability. The final assembly reports included the status of assembly, the number of pieces assembled, the number of pieces stored, the assembly sequence, and the assembly time. Similarly, the development of the SCADA system allowed asset control as well as asset monitoring. The KPIs of the assembly process measured productivity (OTD) and time tracking (ATCT and TA) of the 16 tests, founding that the interconnection and digitization of the scale manufacturing cell were fully integrated and allowed repeatability; the proposed SF architecture represents an alternative for the small and medium automated factories to achieve interconnection and digitization, and it is ready to be tested in a more complex scenario.","2023","2025-04-25 15:31:01","2025-04-25 15:31:01","","101727-101749","","","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

UISCEmod contains both experimental and lumped hydrological models, and the calibration process is automated following a Bayesian approach. The main outputs of UISCEmod include volume, stage, inflow and outflow model time series, calibrated model parameters, and the associated uncertainties. UISCEmod was evaluated at 16 representative sites in Ireland obtaining Nash-Sutcliffe Efficiency (NSE) and Kling-Gupta Efficiency (KGE) above 0.85 for both stage and volume time series for most of the sites, showing its potential for covering the need for a simple, pragmatic, and flexible framework for modelling water levels in ephemeral karstic wetlands with relatively limited input data requirements.","2023-09","2025-04-25 15:31:01","2025-04-25 15:31:01","","","","","167","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Importantly, obtained data can be directly used for multiple applications in fields such as fundamental biology, toxicology, or medicine. Particle movement in biorelevant media can be readily monitored using microscopy and converted into time-resolved trajectories using freely available tracking software. However, translation into tangible and meaningful parameters is time consuming and not always intuitive. We developed new software-MPTHub-as an open-access, standalone, user-friendly tool for the rapid and reliable analysis of particle trajectories extracted from video microscopy. The software was programmed using Python and allowed to import and analyze trajectory data, as well as to export relevant data such as individual and ensemble time-averaged mean square displacements and effective diffusivity, and anomalous transport exponent. Data processing was reliable, fast (total processing time of less than 10 s), and required minimal memory resources (up to a maximum of around 150 MB in random access memory). Demonstration of software applicability was conducted by studying the transport of different polystyrene nanoparticles (100-200 nm) in mucus surrogates. Overall, MPTHub represents a freely available software tool that can be used even by inexperienced users for studying the transport of particles in biorelevant media.","2022-06","2025-04-25 15:31:01","2025-04-25 15:31:01","","","","11","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The inclusion of coupled processes in simulation models is challenged by the high aspect ratio of the fractures, the complex geometry of fracture networks, and the crucial impact of processes that completely change characteristics on the fracture-rock interface. This paper provides a general discussion of design principles for introducing fractures in simulators, and defines a framework for integrated modeling, discretization, and computer implementation. The framework is implemented in the open-source simulation software PorePy, which can serve as a flexible prototyping tool for multiphysics problems in fractured rocks. Based on a representation of the fractures and their intersections as lower-dimensional objects, we discuss data structures for mixed-dimensional grids, formulation of multiphysics problems, and discretizations that utilize existing software. We further present aPythonimplementation of these concepts in the PorePy open-source software tool, which is aimed at coupled simulation of flow and transport in three-dimensional fractured reservoirs as well as deformation of fractures and the reservoir in general. We present validation by benchmarks for flow, poroelasticity, and fracture deformation in porous media. The flexibility of the framework is then illustrated by simulations of non-linearly coupled flow and transport and of injection-driven deformation of fractures.

Although researchers have studied some predictors of OSS project performance, there is a lack of empirical work that studies the impact of project capabilities on the performance of OSS projects. Therefore, this paper studies project capabilities as potential predictors of OSS project performance. The data, gathered from 607 OSS projects over time (in two snap-shots), were consistent with Dynamic Capability Theory (DCT). In other words, the results showed that in order to achieve higher project performance, OSS projects need to have strong capabilities in terms of proactive and efficient defect-removal as well as proactive and efficient functionality-enhancement. The implications of these results for the OSS research community are discussed, followed by recommendations for OSS practitioners. (C) 2011 Elsevier Ltd. APM and IPMA.

The structure of the mitral and tricuspid valves in biventricular hearts has previously been shown to be associated with valve dysfunction. However, the three-dimensional (3D) structure of the entire unrepaired CAVC valve has not been quantified. Understanding the 3D structure of the CAVC may inform optimized repair.Methods: Novel open-source work flows were created in SlicerHeart for the modeling and quantification of CAVC valves on the basis of 3D echocardiographic images. These methods were applied to model the annulus, leaflets, and papillary muscle (PM) structure of 35 patients (29 with trisomy 21) with CAVC using trans -thoracic 3D echocardiography. The mean leaflet and annular shapes were calculated and visualized using shape analysis. Metrics of the complete native CAVC valve structure were compared with those of normal mitral valves using the Mann-Whitney U test. Associations between CAVC structure and atrioventricular valve regurgitation were analyzed.Results: CAVC leaflet metrics varied throughout systole. Compared with normal mitral valves, the left CAVC PMs were more acutely angled in relation to the annular plane (P < .001). In addition, the anterolateral PM was laterally and inferiorly rotated in CAVC, while the posteromedial PM was more superiorly and laterally rotated, relative to normal mitral valves (P < .001). Lower native CAVC atrioventricular valve annular height and annular height-to-valve width ratio before repair were both associated with moderate or greater left atrio-ventricular valve regurgitation after repair (P < .01).Conclusions: It is feasible to model and quantify 3D CAVC structure using 3D echocardiographic images. The results demonstrate significant variation in CAVC structure across the cohort and differences in annular, leaflet, and PM structure compared with the mitral valve. These tools may be used in future studies to catalyze future research intended to identify structural associations of valve dysfunction and to optimize repair in this vulnerable and complex population.

The current study analyzes the effectiveness of machine learning (ML) techniques for the maintainability prediction of OSS systems. In this work large-scale empirical comparisons of thirteen classifiers over seven open source datasets were conducted followed by extensive statistical tests and post hoc analysis to establish the confidence on the performance of one ML technique over another. The results show two important findings: firstly, we observed that overall good prediction accuracy is achieved by almost all ML techniques; secondly the prediction models using genetically adaptive learning ML technique and group method of data handling (GMDH) technique perform better than the other ML techniques in the context of OSS systems. The outcome of this investigation would be helpful for developers in order to predict maintenance behavior of the software at the earlier stages of software development lifecycle (SDLC).

We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors' uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors' motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms' sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms' sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer's OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer's projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.","2021-12-22","2025-04-25 15:31:02","2025-04-25 15:31:02","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Objective: This work is aimed at studying the communication functions of bug comments and their associations with fast and complete bug fixing in OSS development. Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist.

We studied the impact of students' interactions with external collaborators on open source projects and found many similar outcomes between those who communicated remotely and those who communicated face-to-face. However, we also discovered that face-to-face interactions with local software professionals following the Localized Free and Open Source (LFOSS) model had particular advantages in teaching Agile methods, holding students accountable, and introducing professional networking opportunities.","2017","2025-04-25 15:31:02","2025-04-25 15:31:02","","22-27","","","","","","","","","","","Assoc Comp Machinery; ACM SIGCSE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research examines the reception of new contributors in three open source projects to discover whether there are differences in how established contributors respond to new contributors, and if so, what those differences are. Through statistical analysis of time to first response and sentiment analysis of that response to a new contributor's issue, we found that there is a difference in both the speed and content of responses to new contributors' issues as opposed to those of established contributors. This difference suggests that the open source projects we observed are attentive to whether an issue was created by a new contributor and may make an effort to respond in a welcoming manner.","2020","2025-04-25 15:31:02","2025-04-25 15:31:02","","","","","","","","","","","","","Assoc Informat Syst","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers typically test hypotheses on the controlling torques via forward computer models, which allow accepting or rejecting hypotheses on the basis of the fit of model-output plate velocities to kinematic reconstructions. Such models typically require a significant amount of input information (e.g., tectonic boundaries, structure of the lithosphere, lateral variations of rheology, among others) to appropriately model the tectonic system, and obtain sufficiently-realistic realizations of plate motions. Alternatively, the inverse problem approach takes the difference between the plate torque-balance at two distinct moments in time. This results in an equation in which (a) torques that have not varied through time are canceled out and (b) torques that instead have varied through time are linked to the resulting plate-motion change through a term that accounts for the plate shape and the rheology of the underlying asthenosphere. This approach sacrifices the capability to describe the different individual forces/torques acting upon a plate. Instead, it focuses on determining torque temporal variations, which significantly reduces the amount of input knowledge required. In this technical note we introduce MYRIAM, an open-source software that implements such an inverse approach. MYRIAM takes plate-motion temporal changes, and outputs an estimate of the torque variation required upon a plate to generate the input kinematic change. MYRIAM is released as an open-source repository hosted at GitHub, complete with source code and executable files for Windows and Unix-based operating systems. Plain Language Summary The outermost layer of the Earth, known as the lithosphere, is fragmented into plates that are in motion relative to each other. Through geological history, the motion of tectonic plates did not remain steady, and in fact important changes are now known to have occurred relatively fast, within a few million years. By virtue of Newton's laws of motion, these changes are all necessarily caused by the variation in one or more forces acting upon the plates, and therefore disrupt their force balance. Changing the motion of a plate is not an easy feat-for plates it requires overcoming the frictional resistance exerted by the underlying asthenosphere, a low-viscosity layer beneath the plates. The resulting motion change will depend on (a) the mechanical properties of the asthenosphere and (b) the amount of plate surface interacting with said asthenosphere (i.e., the basal area of the plate). All these considerations are taken into account by MYRIAM, an open-source, computationally-inexpensive software that estimates the force/torque variations required to produce a given change of plate motion.","2024-02","2025-04-25 15:31:02","2025-04-25 15:31:02","","","","2","25","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software-continue to-rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. Trust (i.e. full write-access) is `backgrounded' by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.","2014-06","2025-04-25 15:31:02","2025-04-25 15:31:02","","157-169","","2","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Static analyzers can be useful to software developers in detecting and locating code issues and, in addition, classifying their nature. The main problem of static analyzers, however, is that they may signal too many false alarms. Objective. In this paper, we investigate whether code issues that are detected by SpotBugs persist in software code, or if they get removed. We chose SpotBugs because it is one of the best-known and most used static analyzers. Method. We carried out an empirical study on five open-source Java programs and took into account two versions of each of them, to check whether the issues signaled by SpotBugs on the older version had been removed by the time the newer version was released. A total of 1,006 issues were signaled by SpotBugs. Results. Our results show that about half of the issues signaled disappeared between the two versions, but the correction rate was uneven across projects. Issues about the correctness of software code were more likely to be no longer present in the newer version than other types of warnings. Conclusions. Further investigations are required, to understand why some projects appear more active than others in correcting SpotBugs issues, and why very few high-severity warnings were observed in the analyzed code. Nonetheless, the fact that about half of the issues flagged by SpotBugs were removed indicates that the tool is effective in detecting incorrect or otherwise problematic code.","2020","2025-04-25 15:31:02","2025-04-25 15:31:02","","144-151","","","1266","","","","Communications in Computer and Information Science","","","","Univ Algarve; ACM; Quidgest; ATOS","","","","","","","","","ISSN: 1865-0929","","","","","","Shepperd, M; Abreu, FBE; DaSilva, AR; Perez-Castillo, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Unfortunately, external quality metrics can only be calculated after costly software has been developed and deployed for end -users to utilize. Here, we present a method for mining data from freely available open source codebases written in Java to train a Random Forest classifier to predict which files are likely to be external quality hotspots based on their internal quality metrics with over 75% accuracy. We also used the trained model to predict hotspots for a Java project whose data was not used to train the classifier and achieved over 75% accuracy again, demonstrating the method's general applicability to different projects.","2018-03","2025-04-25 15:31:02","2025-04-25 15:31:02","","311-331","","3","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These software packages are now routinely used by researchers and clinicians, and have contributed to important breakthroughs for the understanding of brain anatomy and function. However, no software package exists to process mpMRI data of the spinal cord. Despite the numerous clinical needs for such advanced mpMRI protocols (multiple sclerosis, spinal cord injury, cervical spondylotic myelopathy, etc.), researchers have been developing specific tools that, while necessary, do not provide an integrative framework that is compatible with most usages and that is capable of reaching the community at large. This hinders cross-validation and the possibility to perform multi-center studies. In this study we introduce the Spinal Cord Toolbox (SCT), a comprehensive software dedicated to the processing of spinal cord MRI data. SCT builds on previously-validated methods and includes state-of-the-art MM templates and atlases of the spinal cord, algorithms to segment and register new data to the templates, and motion correction methods for diffusion and functional time series. SCT is tailored towards standardization and automation of the processing pipeline, versatility, modularity, and it follows guidelines of software development and distribution. Preliminary applications of SCT cover a variety of studies, from cross-sectional area measures in large databases of patients, to the precise quantification of mpMRI metrics in specific spinal pathways. We anticipate that SCT will bring together the spinal cord neuroimaging community by establishing standard templates and analysis procedures.","2017-01-15","2025-04-25 15:31:02","2025-04-25 15:31:02","","24-43","","A","145","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bead-based multiplexed bioassays have many technical advantages, including near solution-phase kinetics, small sample volume requirements, many within-assay replicates to reduce measurement error, and, for some bead materials, the ability to synthesize analytes directly on beads via solid-phase synthesis. To allow bead-based multiplexing, analytes can be synthesized on spectrally encoded beads with a 1:1 linkage between analyte identity and embedded codes. Bead-bound analyte libraries can then be pooled and incubated with a fluorescently-labeled macromolecule of interest, allowing downstream quantification of interactions between the macromolecule and all analytes simultaneously via imaging alone. Extracting quantitative binding data from these images poses several computational image processing challenges, requiring the ability to identify all beads in each image, quantify bound fluorescent material associated with each bead, and determine their embedded spectral code to reveal analyte identities. Here, we present a novel open-source Python software package (the mrbles analysis package) that provides the necessary tools to: (1) find encoded beads in a bright-field microscopy image; (2) quantify bound fluorescent material associated with bead perimeters; (3) identify embedded ratiometric spectral codes within beads; and (4) return data aggregated by embedded code and for each individual bead. We demonstrate the utility of this package by applying it towards analyzing data generated via multiplexed measurement of calcineurin protein binding to MRBLEs (Microspheres with Ratiometric Barcode Lanthanide Encoding) containing known and mutant binding peptide motifs. We anticipate that this flexible package should be applicable to a wide variety of assays, including simple bead or droplet finding analysis, quantification of binding to non-encoded beads, and analysis of multiplexed assays that use ratiometric, spectrally encoded beads.","2019-03-22","2025-04-25 15:31:03","2025-04-25 15:31:03","","","","3","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications. By our plug-in, information about measured physiological processes can be obtained and transferred into clinical practice.","2013-04","2025-04-25 15:31:03","2025-04-25 15:31:03","","344-352","","2","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Text Mining techniques are used to categorize defect reports of five OSS projects. Significant variation in the defect resolution time amongst the resulting categories, for each of the sample projects, indicates that a text based classification of defect reports can be useful in early assessment of resolution time before source code level analysis.

Acting as a post-processing tool for a density-functional perturbation theory code (Quantum ESPRESSO) and WANNIER90, EPIq exploits the localization of the deformation potential in the Wannier function basis and the stationary properties of a force-constant functional with respect to the first-order perturbation of the electronic charge density to calculate many electron-phonon related properties with high accuracy and free from convergence issues related to Brillouin zone sampling. EPIq features include: the adiabatic and non-adiabatic phonon dispersion, superconducting properties (including the superconducting band gap in the Migdal-Eliashberg formulation), double-resonant Raman spectra and lifetime of excited carriers. The possibility to customize most of its input makes EPIq a versatile and interoperable tool. Particularly relevant is the interaction with the Stochastic Self-Consistent Harmonic Approximation (SSCHA) allowing anharmonic effects to be included in the calculation of electron -properties. The scalability offered by the Wannier representation combined with a straightforward workflow and easy-to-read input and output files make EPIq accessible to the wide condensed matter and material science communities.Program summaryProgram Title: EPIqCPC Library link to program files: https://doi .org /10 .17632 /f2syws66d7 .1Developer's repository link: https://gitlab .com /the -epiq-team /epiq Licensing provisions: GPLv3Programming language: FORTRAN95External routines: BLAS (http://www /netlib .org /blas), LAPACK (http://www .netlib .org /lapack), Quantum ESPRESSO (https://www .quantum -espresso .org/), wannier90 (https://wannier .org/)Nature of problem: Direct first principles calculation of quantities obtained via linear response methods in solid-state systems, such as the deformation potential, can be computationally demanding, hindering proper convergence.Solution method: An interpolation scheme exploiting the localization of the deformation potential in the Wannier function basis and the stationary properties of a force-constant functional with respect to the first- order perturbation of the electronic charge density is implemented in EPIq.

Unfortunately, there is no such software framework in the research community. This paper studies the combination of some open-source frameworks for high fidelity simulation of CRN. In particular, some challenges are highlighted for the combination of radio simulators (e.g. GNU Radio, CogWave) and network simulators (e.g. OMNeT++, ns3) at the level of network layer, data link layer and physical layer.

State-of-the-art characterization of sample materials related to these fields, deploying high-end instrumentation, allows for gathering large quantities of molecular composition data. One established technological platform is ultrahigh-resolution mass spectrometry, e.g., Fourier-transform mass spectrometry (FT-MS). However, the huge amounts of data acquired in FT-MS often result in tedious data treatment and visualization. FT-MS analysis of complex matrices can easily lead to single mass spectra with more than 10,000 attributed unique molecular formulas. Sophisticated software solutions to conduct these treatment and visualization attempts from commercial and noncommercial origins exist. However, existing applications have distinct drawbacks, such as focusing on only one type of graphic representation, being unable to handle large data sets, or not being publicly available. In this respect, we developed a software, within the international complex matrices molecular characterization joint lab (IC2MC), named “python tools for complex matrices molecular characterization” (PyC2MC). This piece of software will be open-source and free to use. PyC2MC is written under python 3.9.7 and relies on well-known libraries such as pandas, NumPy, or SciPy. It is provided with a graphical user interface developed under PyQt5. The two options for execution, (1) a user-friendly route with a prepacked executable file or (2) running the main python script through a Python interpreter, ensure a high applicability but also an open characteristic for further development by the community. Both are available on the GitHub platform (https://github.com/iC2MC/PyC2MC_viewer).","2023-04-05","2025-04-25 15:31:03","2025-04-25 15:31:03","","617-626","","4","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

E-portfolios with mobile capabilities allow even more flexibility. However, the development or acquisition of ePortfolio software is often costly, and at the same time, commercially available systems may not sufficiently fit the institution's needs. The aim of this study was to design and evaluate an ePortfolio system with mobile capabilities using a commercially free and open source software solution. Methods: We created an online ePortfolio environment using the blogging software WordPress based on reported capability features of such software by a qualitative weight and sum method. Technical implementation and usability were evaluated by 25 medical students during their clinical training by quantitative and qualitative means using online questionnaires and focus groups. Results: The WordPress ePortfolio environment allowed students a broad spectrum of activities - often documented via mobile devices - like collection of multimedia evidences, posting reflections, messaging, web publishing, ePortfolio searches, collaborative learning, knowledge management in a content management system including a wiki and RSS feeds, and the use of aid tools for studying. The students' experience with WordPress revealed a few technical problems, and this report provides workarounds. The WordPress ePortfolio was rated positively by the students as a content management system (67 % of the students), for exchange with other students (74 %), as a note pad for reflections (53 %) and for its potential as an information source for assessment (48 %) and exchange with a mentor (68 %). On the negative side, 74 % of the students in this pilot study did not find it easy to get started with the system, and 63 % rated the ePortfolio as not being user-friendly. Qualitative analysis indicated a need for more introductory information and training. Conclusions: It is possible to build an advanced ePortfolio system with mobile capabilities with the free and open source software WordPress. This allows institutions without proprietary software to build a sophisticated ePortfolio system adapted to their needs with relatively few resources. The implementation of WordPress should be accompanied by introductory courses in the use of the software and its apps in order to facilitate its usability.","2016-06-03","2025-04-25 15:31:04","2025-04-25 15:31:04","","","","","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This community faces a new and unusual situation. The traditional difficulties of gathering enough empirical data have been replaced by issues of dealing with enormous amounts of freely available public data from many disparate sources (online discussion forums, source code directories, bug reports, OSS Web portals, etc.). Consequently, these data are being discovered, gathered, analyzed, and used to support multidisciplinary research. However at present, no means exist for assembling these data under common access points and frameworks for comparative, longitudinal, and collaborative research across disciplines. Gathering and maintaining large F/OSS data collections reliably and making them usable present several research challenges. For example, current projects usually rely on direct access to, and mining of raw data from groups that generate it, and both of these methods require unique effort for each new corpus, or even for updating existing corpora. In this paper, we identify several needs and critical factors in F/OSS empirical research across disciplines, and suggest recommendations for design of a global research infrastructure for multi-disciplinary research into F/OSS development.","2008","2025-04-25 15:31:04","2025-04-25 15:31:04","","143+","","","275","","","","International Federation for Information Processing","","","","IFIP WG 2 3","","","","","","","","","ISSN: 1571-5736","","","","","","Russo, B; Damiani, E; Hissam, S; Lundell, B; Succi, G","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

Mobile sensing researchers often program data processing and analysis code from scratch even though many research teams collect data from similar mobile sensors, platforms, and devices. This leads to significant inefficiency in not being able to replicate and build on others' work, inconsistency in quality of code and results, and lack of transparency when code is not shared alongside publications. We provide an overview of Reproducible Analysis Pipeline for Data Streams (RAPIDS), a reproducible pipeline to standardize the preprocessing, feature extraction, analysis, visualization, and reporting of data streams coming from mobile sensors. RAPIDS is formed by a group of R and Python scripts that are executed on top of reproducible virtual environments, orchestrated by a workflow management system, and organized following a consistent file structure for data science projects. We share open source, documented, extensible and tested code to preprocess, extract, and visualize behavioral features from data collected with any Android or iOS smartphone sensing app as well as Fitbit and Empatica wearable devices. RAPIDS allows researchers to process mobile sensor data in a rigorous and reproducible way. This saves time and effort during the data analysis phase of a project and facilitates sharing analysis workflows alongside publications.","2021-11-18","2025-04-25 15:31:04","2025-04-25 15:31:04","","","","","3","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In-depth analysis of the CoCs demonstrated many discrepancies in the terminology, length, enforcement, and adoption of codes of conduct. To investigate the usage of these CoCs, we investigate five women-focused OSS discussion forums. This analysis shows the value of creating/adopting a CoC and the impact CoC can have on the participation of women. We also present the challenges in the usage and enforcement of CoCs as discussed by women of these forums.

A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study. We reveal that Landsat 8 data combined with texture analysis can accurately detect these artificial landmarks across the heterogeneous environment of OROAFR; 75.68% of artificial water points within the site were successfully identified and false positive detection rate was minimal at 7.69%. The methodological framework developed for this work, based on the treatment of freely available satellite data using open source software, adds to other works attempting to help monitor threats to biodiversity in desert ecosystems, enabling up-to-date information on the level of anthropogenic activities in these habitats to be easily and regularly collected.","2015-10","2025-04-25 15:31:04","2025-04-25 15:31:04","","61-72","","1","1","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This chapter uses coordination theory to analyze the bug fixing processes in the proprietary operating system development group of a large minicomputer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel. Three approaches to identifying dependencies and coordination mechanisms are presented. Mechanisms analyzed include those for task assignment, resource sharing, and managing dependencies between modules of source code. The proprietary development organization assigned problem reports to engineers based on the module that appeared to be in error, because engineers only worked on particular modules. Alternative task assignment mechanisms include assignment to engineers based on workload or voluntary assignment, as in Linux. In the proprietary process, modules of source code were not shared but, rather, were “owned” by one engineer, thus reducing the need for coordination. In Linux, where multiple developers can work on the same modules, alternative resource sharing mechanisms have been developed to manage source code. Finally, the proprietary developers managed dependencies between modules informally, relying on their personal knowledge of which other engineers used their code. The Linux process allows developers to change code in multiple modules, but emphasizes modularity to reduce the need to do so. By helping in the identification of dependencies in the bug fixing processes, drawing upon coordination theory streamlines bug fixing activities of a large mini-computer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel.","2008","2025-04-25 15:31:04","2025-04-25 15:31:04","","69-99","","","9","","","","Advances in Management Information Systems","","","","","","","","","","","","","ISSN: 1554-6152","","","","","","Grover, V; Markus, ML","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many open source software products are used to access and navigate through the Dark Web. Together they form the Dark Web open source software ecosystem. Research on this ecosystem is scarce and research on the ecosystem health is non-existent, even though ecosystem health is an useful indicator of the livelihood of an ecosystem. The goal of this research is to evaluate the health of the ecosystem through an assessment of Tor, I2P and GitHub. The Open Source Ecosystem Health Operationalization framework is used to help perform this assessment. Eight metrics from the framework are selected, which are measured using the data collected. Analysis of Tor and I2P metrics suggest that there has been an increase in Tor and I2P user activity in the recent past. Added knowledge, spin offs and forks and usage indicate active participation and interest in Tor and I2P. There has also been an increase in the number of active GitHub Dark Web projects. However, these GitHub projects are not well-connected and only a small number of projects have a large number of contributors. There is some variety among the GitHub software projects.

There are many methods which are being followed to make the students understand concepts. One such method is the use of CAD tools When computers came into class rooms, the need for CAD tools also arose [1]. They help the students to visualize many basic concepts which, they otherwise cannot see in the physical world. In this 21st century, dominated by social networking, the tools required to educate them have also come to be available in free of cost. Such tools are called open source software or FOSS tools. We have proposed a teaching methodology that involves the usage of open source software tools along with traditional teaching which enable the communication engineering students to understand complex concepts pertaining to the subject of Antenna and wave propagation. We carried out an experiment with forty students from fifth semester Electronics and Communication Engineering department. The students used a FOSS tool and gave a test based on designing of various antennas with desired radiation patterns by selecting different parameters before and after using the tool. The scores of the two tests show that there was an increase in the marks obtained by students in the test after using the tool. Thus the use of FOSS tool helped students perform better in the test. This may be because the tool has visualizations which help student understand the abstract concepts such as antenna radiation pattern and wave propagation.","2013","2025-04-25 15:31:05","2025-04-25 15:31:05","","101-104","","","","","","","IEEE International Conference on Technology for Education","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 2372-7217","","","","","","Kinshuk; Iyer, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the popularity of open-source software, we argue that the next job title can be predicted based on a candidate's past expertise in the open-source community. On the other hand, the career path can also affect the development of a talent's expertise. Motivated by the observation, we propose to predict the job titles of IT talents as a dual task of forecasting their expertise development in open-source software. To solve the task, we design a dual learning model DualJE that leverages both the data-level and model-level duality. Experimental results show that DualJE is effective and performs much better than comparative models.

To address this, our institution has developed an undergraduate course in which students contribute to Free and Open Source Software (FOSS) projects under the guidance of a dedicated mentor. By contributing to FOSS projects, students can: find a mentor or role model; collaborate with, participate in, and contribute to a welcoming and supporting community; and see that they can have real-world positive impact. This paper describes the course and our experiences in teaching it, and provides evidence that it can have a positive impact on diversity by increasing retention and improving students' confidence.","2018","2025-04-25 15:31:05","2025-04-25 15:31:05","","","","","","","","","","","","","IEEE Special Tech Community Broadening Participat","","","","","","","","","","","","","","","Payton, J; Thiruvathukal, GK; Burge, J; Stukes, F; Rankin, Y; Dillon, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the inaugural meeting, four special interest groups (SIGs) were established. The Software SIG was charged with identifying projects that focus on open-source software for image visualization and analysis. To date, two projects have been defined by the Software SIG. The eXtensible Imaging Platform project has produced a rapid application development environment that researchers may use to create targeted workflows customized for specific research projects. The Algorithm Validation Tools project will provide a set of tools and data structures that will be used to capture measurement information and associated needed to allow a gold standard to be defined for the given database against which change analysis algorithms can be tested.

Design/methodology/approach - A quantitative study was designed using choose tasks that were carried out via the email discourse on the developers' email fora in five FLOSS projects. Choice process episodes were selected as the unit of analysis and were coded for the task trigger and topic. The impact of these factors on participation (i.e. the numbers of participants and messages) was assessed by regression. Findings - The results reveal differences in participation related to different task triggers and task topics. Further, the results suggest the mediating role of the number of participants in the relationships between task characteristics and the number of messages. The authors also speculate that project type serves as a boundary condition restricting the impacts of task characteristics on the number of participants and propose this relationship for future research. Research limitations/implications - Empirical support was provided to the important effects of different task characteristics on individual participation behaviors in FLOSS development tasks. Practical implications - The findings can help FLOSS participants understand participation patterns in different tasks and choose the types of tasks to attend to. Originality/value - This research explores the impact of task characteristics on participation in FLOSS development at the task level, while prior research on participation in FLOSS development has focused mainly on factors at the individual and/or project levels.","2021-07-12","2025-04-25 15:31:05","2025-04-25 15:31:05","","1177-1202","","4","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is a complicated social process to understand. OSS is a multi-faceted phenomenon including code, a licensing structure, a community, development best practices, a method of diffusion. However, the current OSS collaborative researches place too much emphasis on collaborative behaviors, but ignore the study on collaborative process. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and level of collaboration between collaborators. Based on the definition of three types of contact behavior, this paper presents an approach to measuring the contact relationship intensity. Based on introducing and improving TF-IDF (term frequency-inverse document frequency), this paper presents the methods for calculating tag weights and work similarity between collaborators. Finally, by evaluating the model using data from the OSS websitewww.Codeplex.com, we verify that our model outperforms conventional models in both describing and forecasting collaborative behavior.","2014","2025-04-25 15:31:05","2025-04-25 15:31:05","","77-86","","1","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The Madagascar, based on Python, is usually supposed to be better in the development of processing technologies due to its capabilities of multidimensional data analysis and reproducibility. However, this open-source software has not been widely used so far for field data processing because of complicated interfaces and data structure system. To verify the effectiveness of the Madagascar software on field data, we applied it to a typical seismic data processing flow including data loading, geometry build-up, F-K filter, predictive deconvolution, velocity analysis, normal moveout correction, stack, and migration. The field data for the test were acquired in Gunsan Basin, Yellow Sea using a streamer consisting of 480 channels and 4 arrays of air-guns. The results at all processing step are compared with those processed with Landmark's ProMAX (SeisSpace R5000) which is a commercial processing software. Madagascar shows relatively high efficiencies in data IO and management as well as reproducibility. Additionally, it shows quick and exact calculations in some automated procedures such as stacking velocity analysis. There were no remarkable differences in the results after applying the signal enhancement flows of both software. For the deeper part of the substructure image, however, the commercial software shows better results than the open-source software. This is simply because the commercial software has various flows for de-multiple and provides interactive processing environments for delicate processing works compared to Madagascar. Considering that many researchers around the world are developing various data processing algorithms for Madagascar, we can expect that the open-source software such as Madagascar can be widely used for commercial-level processing with the strength of expandability, cost effectiveness and reproducibility.","2018-08","2025-04-25 15:31:05","2025-04-25 15:31:05","","171-182","","3","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We successfully applied the framework to implement a set of quality assurance interventions in the Robot Operating System community. The framework we proposed is composed of three components, interventions design, democratization, and execution. We believe that this process will work for other FOSS communities too.

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors' engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors' attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023-05-01","2025-04-25 15:31:06","2025-04-25 15:31:06","","3106-3130","","5","49","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Y.","Uncovering the relationship between OSS user support networks and OSS popularity","DECISION SUPPORT SYSTEMS","","0167-9236","10.1016/j.dss.2014.05.014","","The open source model of software development has become an attractive alternative to the traditional proprietary approach. However, the incomplete understanding of the phenomenon has continued to prompt researchers to investigate factors that could increase the use and popularity of open source software (ass). While a key antecedent for OSS use highlighted in the previous literature is the software quality, we propose that effective online user support is also necessary to increase its popularity. As an understudied area, this paper seeks to understand the role of online user support networks in facilitating OSS use. Based on the network embeddedness theory, it suggests that properties of the user support network i.e., variation in structural and junctional embeddedness, measured as the in-degree and betweenness centralizations respectively, would affect OSS popularity in terms of the number of active users and downloads of the software. Testing on a sample of 176 OSS projects from Sourceforge.net, we showed that a negative quadratic relationship exists between the variation in structural embeddedness of the OSS user support network and the software popularity. Further, as hypothesized, the variation in junctional embeddedness was found to positively impact the OSS popularity. Theoretical and practical implications of the study are discussed.

Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when “simple stupid bugs” were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub. Leveraging a statistical survival model and other non-parametric statistical tests, we found that there were two main categories of categorical variables that affect a bug's life; Time Factors and Author Factors. We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time. These findings will provide vital insight to help the open-source community mitigate the abundance of code and can be used in future research to aid in bug-finding programs.","2023-03","2025-04-25 15:31:06","2025-04-25 15:31:06","","","","5","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Quantitative analysis of AOSLO images typically requires manual grading, which is time consuming, and subjective; thus, automated algorithms are highly desirable. Previously developed automated methods are often reliant on ad hoc rules that may not be transferable between different imaging modalities or retinal locations. In this work, we present a convolutional neural network (CNN) based method for cone detection that learns features of interest directly from training data. This cone-identifying algorithm was trained and validated on separate data sets of confocal and split detector AOSLO images with results showing performance that closely mimics the gold standard manual process. Further, without any need for algorithmic modifications for a specific AOSLO imaging system, our fully-automated multi-modality CNN-based cone detection method resulted in comparable results to previous automatic cone segmentation methods which utilized ad hoc rules for different applications. We have made free open-source software for the proposed method and the corresponding training and testing datasets available online.","2017-07-26","2025-04-25 15:31:06","2025-04-25 15:31:06","","","","","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Calibration of fluorescence measurements from flow cytometry and plate reader spectrophotometry has been implemented previously, but the tools are disjointed. Here we pull together, and in some cases improve, extant methods into a single software tool, written as a package in the R statistical framework. The workflow is validated using Escherichia coli engineered to express green fluorescent protein (GFP) from a set of commonly used constitutive promoters. We then demonstrate the package's power by identifying the time evolution of distinct subpopulations of bacteria from bulk plate reader data, a task previously reliant on laborious flow cytometry or colony counting experiments.

Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio [finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing.

Unfortunately this goal has not been achieved mainly due to a lack of both tools and data management, as data must be gathered from different sources and in different formats. Compounding this problem is the fact that in some regions different water agencies are in charge of water supply as is the case in the Basin of Mexico, in which Mexico City and its Metropolitan Zone are located. The inhabitants of the Basin of Mexico, which comprises five different political entities and in which different agencies are in charge of water supply rely on the Basin's aquifer system as its main water supply source. However, a regional hydrogeological database in this area does not exist which is why the use of both a Relational Database Management System (RDMBS) and a Geographic Information System (GIS) is proposed in order to improve regional data management in the study area. Data stored in this new database, the Basin of Mexico Hydrogeological Database (BMHDB) comprise data on climatological, borehole and run-off variables, readily providing information for the development of hydrogeological models. A simple example is used to show how geostatistical analysis can be done using the data directly from the BMHDB. The structure of the BMHDB allows easy maintenance and updating, representing a valuable tool for the development of regional studies. (c) 2008 Elsevier Ltd.

Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 15:31:07","2025-04-25 15:31:07","","119-139","","1","39","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

GaugeCam Remote Image Manager-Educational 2 (GRIME2) is a mature, open-source commercial friendly software application that automatically detects and measures water level in laboratory and field settings. The software relies on a dedicated target background for water line detection and image calibration. The system detects the change in pixel gray scale values associated with the intersection of the water level at the target surface. Fiducials on the target background are used to precisely create a pixel to real world coordinate transfer matrix and to correct for camera movement. The presented software package implements the algorithms and automates the water level measurement process, annotation of images with result overlays, creation of animations, and output of results to files that can be further analyzed in a spreadsheet or with R or Python. These GRIME2 features are illustrated using imagery from a coastal marsh field site. Tradeoffs between workflow and algorithm complexity and ease of use are discussed and future improvements are identified with the intention that this Findable, Accessible, Interoperable, and Reusable-inspired software can be adopted, modified and improved by the user community. While image resolution, quality and other factors associated with field deployment (e.g., water surface roughness, sun glare, shadows, and bio-fouling) will have an impact on measurement quality, previous controlled laboratory testing that did not manifest these issues showed potential for accuracy of +/- 3 mm (Gilmore et al., 2013, ).","2022-08","2025-04-25 15:31:07","2025-04-25 15:31:07","","","","8","58","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The model has an outer layer exchanging radiation and heat with the environment and a stack of layers beyond modifying the thermal behavior. The orientation of the layer is defined by the normal vector of the surface. The innermost layer is at a constant or variable temperature called core temperature. All the layers have heat capacity and thermal conductivity. The outer layers properties are color (visible), emissivity (IR), coefficients of free and forced convection, and a factor for latent heat. The environmental parameters are air temperature, wind speed, relative humidity, irradiation of the sun, and thermal radiation of the sky and ground. The properties of the model (7 parameters) are fitted to minimize the difference between the prediction and a time series of measured temperatures. The size of the time series is one or more days with 288 values per day (5 minute resolution). The model is useable for very different objects like backgrounds (meadow, forest, rocks, sand, or bricks) or parts of objects like vehicles. The STANDCAM is a decoy of a vehicle and is used to constitute a thermal signature and is not classified. The STANDCAM has a complex CAD-Model with thousands of triangular facets that had to be simplified for the thermal simulation. The CAD model was available through WTD 52, an agency of the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw). Groups of elements of the model facing in the same direction and behaving similarly were cut out and grouped in distinct objects. The calculation of the temperature of the objects is based on measured environmental data and the model parameters are fitted on measured radiation temperatures of the objects and backgrounds. For the visualization the object is surrounded by a world texture. For the radiation temperature of the environment and the ground under the object measured air and meadow temperatures were used. The temperature is coded as a color from a palette (here we use a grey palette) and is updated regularly throughout the calculation of the scene for the selected view and is stored as a texture bitmap. The animation of the temperature textures is directly performed by BLENDER. The result of the visualization is available as movie that is watchable in real time or time lapse.","2018","2025-04-25 15:31:07","2025-04-25 15:31:07","","","","","10794","","","","Proceedings of SPIE","","","","SPIE","","","","","","","","","ISSN: 0277-786X","","","","","","Stein, KU; Schleijpen, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our laboratory exploits PCR techniques and Next Generation Sequencing (NGS) methods to perform high-throughput integration site monitoring in different clinical trials and scientific projects. Because of the huge amount of samples that we process every year, which result in hundreds of millions of sequencing reads, we need to standardize data management and tracking systems, building up a scalable and flexible structure with web-based interfaces, which are usually called Laboratory Information Management System (LIMS). Methods: We started collecting end-users' requirements, composed of desired functionalities of the system and Graphical User Interfaces (GUI), and then we evaluated available tools that could address our requirements, spanning from pure LIMS to Content Management Systems (CMS) up to enterprise information systems. Our analysis identified ADempiere ERP, an open source Enterprise Resource Planning written in Java J2EE, as the best software that also natively implements some highly desirable technological advances, such as the high usability and modularity that grants high use-case flexibility and software scalability for custom solutions. Results: We extended and customized ADempiere ERP to fulfil LIMS requirements and we developed adLIMS. It has been validated by our end-users verifying functionalities and GUIs through test cases for PCRs samples and pre-sequencing data and it is currently in use in our laboratories. adLIMS implements authorization and authentication policies, allowing multiple users management and roles definition that enables specific permissions, operations and data views to each user. For example, adLIMS allows creating sample sheets from stored data using available exporting operations. This simplicity and process standardization may avoid manual errors and information backtracking, features that are not granted using track recording on files or spreadsheets. Conclusions: adLIMS aims to combine sample tracking and data reporting features with higher accessibility and usability of GUIs, thus allowing time to be saved on doing repetitive laboratory tasks, and reducing errors with respect to manual data collection methods. Moreover, adLIMS implements automated data entry, exploiting sample data multiplexing and parallel/transactional processing. adLIMS is natively extensible to cope with laboratory automation through platform-dependent API interfaces, and could be extended to genomic facilities due to the ERP functionalities.","2015-06-01","2025-04-25 15:31:07","2025-04-25 15:31:07","","","","9","16","","","","","","","","","","","","","","","","","Publisher: Bioinformat Italian Soc","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Highspeed, high resolution imaging can reveal dynamic events such as changes in blood flow and responses to stimulation. Despite these benefits, commercially available scientific cameras rarely include software that is suitable for in-vivo imaging applications, making this highly versatile form of optical imaging challenging and time-consuming to implement. To address this issue, we have developed a novel, open-source software package to control high-speed, multispectral optical imaging systems. The software integrates a number of modular functions through a custom graphical user interface (GUI) and provides extensive control over a wide range of inexpensive IEEE 1394 Firewire cameras. Multispectral illumination can be incorporated through the use of off-the-shelf light emitting diodes which the software synchronizes to image acquisition via a programmed microcontroller, allowing arbitrary high-speed illumination sequences.

In this work, each bug report is endowed with a response variable (bug-fixing time), external to its words, that we are interested in predicting. To analyze the bug reports collections, we used a supervised Latent Dirichlet Allocation (sLDA), whose goal is to infer latent topics that are predictive of the response. The bug reports and the responses are jointly modeled, to find latent topics that will best predict the response variables for future unlabeled bug reports. With a fitted model in hand, we can infer the topic structure of an unlabeled bug report and then form a prediction of its response. sLDA adds to LDA a response variable connected to each bug report. Two different variants of the bag-of-words (BoW) model are used as baseline discriminative algorithms and also an unsupervised LDA is considered. To evaluate the proposed approach the defect tracking dataset of LiveCode, a well-known and large dataset, was used. Results show that SLDA improves recall of the predicted bug-fixing times compared to other BoW single topic or multi-topic supervised algorithms.","2022","2025-04-25 15:31:07","2025-04-25 15:31:07","","233-240","","","","","","","","","","","INSTICC","","","","","","","","","","","","","","","Kaindl, H; Mannion, M; Maciaszek, L","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within this literature, polycentric urban regions are commonly defined as territories that have multiple, proximately located (sub)centers and are characterized by balanced urban development. However, analytical-operational frameworks to identify and classify PURs are often ad hoc efforts to answer a specific research question and underlying work is often shelved rather than shared and/or made accessible. As a result, challenges associated with generalizability, reproducibility, and replicability clearly loom large in the urban polycentricity literature. Against this backdrop, this article describes the discrepancy between a rich debate on polycentricity and the paucity of tools enabling the disambiguation and reproducibility of results claimed by various authors around this polysemic concept. We present an online and open tool-PURban-that brings together the major analytical-operational frameworks and data sets in urban polycentricity research and allows parametrizing key operational choices. To illustrate the tool, we demonstrate how it facilitates the identification, mapping and analysis of degrees of morphological polycentricity in European urban systems.

In recent years, dose-surface maps (DSMs) have become increasingly popular for characterization of spatial dose distributions and identification of radiosensitive subregions for hollow organs. However, methodological variations and lack of open-source, publicly offered code-sharing between research groups have limited reproducibility and wider adoption. Purpose This paper presents rtdsm, an open-source software for DSM calculation with the intent to improve the reproducibility of and the access to DSM-based research in medical physics and radiation oncology. Methods A literature review was conducted to identify essential functionalities and prevailing calculation approaches to guide development. The described software has been designed to calculate DSMs from DICOM data with a high degree of user customizability and to facilitate DSM feature analysis. Core functionalities include DSM calculation, equivalent dose conversions, common DSM feature extraction, and simple DSM accumulation. Results A number of use cases were used to qualitatively and quantitatively demonstrate the use and usefulness of rtdsm. Specifically, two DSM slicing methods, planar and noncoplanar, were implemented and tested, and the effects of method choice on output DSMs were demonstrated. An example comparison of DSMs from two different treatments was used to highlight the use cases of various built-in analysis functions for equivalent dose conversion and DSM feature extraction. Conclusions We developed and implemented rtdsm as a standalone software that provides all essential functionalities required to perform a DSM-based study. It has been made freely accessible under an open-source license on Github to encourage collaboration and community use.","2022-11","2025-04-25 15:31:08","2025-04-25 15:31:08","","7327-7335","","11","49","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They provide critical information and enhance environmental integrity in planning and development of GHG mitigation policy. The characteristics of a high quality inventory are that it follows good practice according to the IPCC guidelines. The key components of good practice are that the inventory is transparent to others, has accurate and complete emissions estimates for all gases, sources and sinks; has consistent application of methods across time; and is comparable to inventories from other countries [1]. While developed countries struggle with implementation of good practice, most can produce reasonably high quality inventories [2]. However, the task is more challenging in low lying pacific island countries. Some of the specific challenges include: lack of clarity on roles and responsibilities of agencies in preparing inventories; small teams with limited resources; difficulty in retaining expertise; incomplete or non-existent activity data; inconsistent data between inventories; absence of an archiving system for previous inventories; no QA/QC plan [3]. As part of the UN-REDD Programme project on “Strengthening Regional Support to National Forest Monitoring Systems for REDD+ in the Pacific” a Regional Monitoring System has been developed to support low lying pacific island countries (Republic of Palau, Tuvalu, Cook Islands, Tonga, Republic of Kiribati, and Federated States of Micronesia). Using the Republic of Palau as a case study, we present this system and focus on four main challenges; 1) improving activity data compilation through systematic land use assessment 2) application of simple land use mapping algorithms 3) application of a regional geo-spatial portal to support improved data management 4) application of open-source land use analysis systems to help manage and analyze inventory data.","2015","2025-04-25 15:31:08","2025-04-25 15:31:08","","3361-3364","","","","","","","IEEE International Symposium on Geoscience and Remote Sensing IGARSS","","","","IEEE","","","","","","","","","ISSN: 2153-6996","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Clients may struggle to select the best OSS-LMS package from a wide range of options, leading to a complex multi-criteria group decision -making (MCGDM) problem. This evaluates OSS-LMS packages based on several criteria like us-ability, functionality, e-learning standards, reliability, activity tracking, course development, assess-ment, backup and recovery, error reporting, efficiency, operating system compatibility, computer -managed instruction, authentication, authorization, troubleshooting, maintenance, upgrading, and scalability. Handling uncertain data is a vital aspect of OSS-LMS package evaluation. To tackle MCGDM issues, this study presents a consensus weighted sum product (c-WASPAS) method which is applied to an educational OSS-LMS package selection problem to evaluate four OSS-LMS pack-ages, namely ATutor, eFront, Moodle, and Sakai. The findings indicate that the priority order of alternatives is Moodle > Sakai > eFront > ATutor and, therefore, MOODLE is the best OSS-LMS package for the case study. A sensitivity analysis of criteria weights is also conducted, as well as a comparative study, to demonstrate the effectiveness of the proposed method. It is essential to note that proper OSS-LMS package evaluation is crucial to avoid negative impacts on organizational per-formance. By addressing MCGDM issues and dealing with uncertain information, the c-WASPAS method presented in this study can assist clients in selecting the most appropriate OSS-LMS pack-age from multiple alternatives. The findings of this study can benefit educational institutions and other organizations that rely on OSS-LMS packages to run their operations.","2023","2025-04-25 15:31:08","2025-04-25 15:31:08","","529-556","","3","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Through an empirical, interpretive case study and a literature review utilising the metaphor of text in the analysis, this paper provides a refined conceptualisation of user participation in OSS development. Findings - The paper reveals that different kinds of meanings have been attached to users and to their participation. User participation is both direct and indirect in the OSS development context. Some user groups actively take part in OSS development, while others are merely represented in it. Different kinds of intermediaries “representing the users” are identified. Research limitations/implications - The research is based on one case study on a small but active OSS project with an interest in users. Other kinds of OSS projects should be analysed. The analysis was focused on a discussion forum, but users can take part in OSS development by other means as well. Paths for future work should include the gathering of more varied empirical data. Practical implications - The findings indicate that users can provide feedback to the development through discussion forums in the distributed environment, but there is a need to support the users in doing so and the developers in analysing the data. The importance of different kinds of intermediaries “representing the users” is highlighted. Originality/value - The paper provides thorough empirical insights and a refined conceptualisation of user participation addressing the currently weakly empirically explored OSS development context.","2009","2025-04-25 15:31:08","2025-04-25 15:31:08","","132-156","","2","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This would help software developers to judiciously allocate the resources used for testing and maintenance. Software metrics can be used for constructing various classification models which can be used for timely identification of change prone classes. Search based algorithms which form a subset of machine learning algorithms can be utilized for constructing prediction models to identify change prone classes of software. Search based algorithms use a fitness function to find the best optimal solution among all the possible solutions. In this work, we analyze the effectiveness of hybridized search based algorithms for change prediction. In other words, the aim of this work is to find whether search based algorithms are capable for accurate model construction to predict change prone classes. We have also constructed models using machine learning techniques and compared the performance of these models with the models constructed using Search Based Algorithms. The validation is carried out on two open source Apache projects, Rave and Commons Math. The results prove the effectiveness of hybridized search based algorithms in predicting change prone classes of software. Thus, they can be utilized by the software developers to produce an efficient and better developed software. (C) 2016 Elsevier Ltd.

Here, we present an R packagecalled IsoMatchMS for the automated annotation ofMALDI-MS data for multiple datatypes: intact proteins, peptides, andglycans. This tool accepts already derived molecular formulas or,for proteomics applications, can derive molecular formulas from alist of input peptides or proteins including proteins with post-translationalmodifications.

Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.","2021-09-25","2025-04-25 15:31:08","2025-04-25 15:31:08","","","","1","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is mainly developed by developers, volunteers, and users all over the world, but its reliability has been widely questioned. When OSS faults are detected, volunteers or users send them to developers by email or network. After the developer confirms the fault, it will be randomly assigned to the debugger who may be a developer, a volunteer, or a user. These open source community contributors also have the phenomenon of learning when removing faults. When the detected faults are removed, the number of introduced faults decreases gradually. Therefore, this study proposes a software reliability model with the decreasing trend of fault introduction in the process of OSS development and testing. The validity of the proposed model and the accuracy of estimating residual faults are verified by experiments. The proposed model can be used to evaluate the reliability and predict the remaining faults in the actual OSS development and testing process.","2022","2025-04-25 15:31:08","2025-04-25 15:31:08","","","","5","17","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We are dependent on software controlled by global technology giants. The dependence on commonly used services and platforms provided by Microsoft, Google or Amazon must be removed to achieve digital sovereignty. Open-source software has been readily available for a long time, but studies looking into excluding all proprietary software from working life are scarce. This paper investigates the feasibility of replacing proprietary software as a step towards digital sovereignty. The ability to self-host services is key to ensuring independence, and the ability to verify software code is key to ensuring integrity. Therefore open-source code and transparency are transient properties for sovereign software. We present problems by mapping the problematic software used by teachers, researchers and student assistants at Arcada UAS with a varied set of requirements on the digital tools of their daily lives. We research alternatives and deploy a suite of software compatible with EU policies on digital sovereignty. We rely on many services offered by tech giants in our professional lives. There are several open-source software suites that can be self-hosted and that have permissive licenses for business use. Extensive technical knowledge is required for the deployment of software. Most daily tasks can be accomplished by using sovereign software, although not all needs of the test group were met. Companies can deploy sovereign software for most daily tasks, reducing dependency on tech giants. However, software adoption was low. Arcadas IT-support does not host, enforce or endorse the usage of sovereign software. Public code repositories enable independent code verification, in contrast to proprietary software. Some software cannot be easily replaced, and digital habits are hard to change.","2024","2025-04-25 15:31:08","2025-04-25 15:31:08","","106-113","","","1027","","","","Lecture Notes in Networks and Systems","","","","Fac Arcada Univ Appl Sci; Int Assoc Online Engn, Global Online Lab Consortium; Phoenix Contact; Int Educ Network; Edunet World Assoc; Air France; KLM","","","","","","","","","ISSN: 2367-3370","","","","","","Auer, ME; Langmann, R; May, D; Roos, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Low-cost spectroscopy is one such application and mobile phone camera-based instruments have been used in pollution monitoring, medical applications in developing countries and vegetation analysis. Can such an instrument be developed and tested to assist with automated detection of materials, possibly from space? We tested two spectrometer designs inside a two unit (2U) cubesat frame against a series of materials exhibiting phenomenology in the visible/near infrared (Vis/NIR) portion of the spectrum and vegetation groups. This was conducted in order to determine whether open source designs were capable of discriminating against similar materials, such as types of vegetation or types of iron-rich minerals.

The skeletal muscle chemoelectromechanical model is based on a bottom-up approach modeling the entire excitation-contraction pathway by strongly coupling a detailed biophysical model of a half-sarcomere to the propagation of action potentials along skeletal muscle fibers and linking cellular parameters to a transversely isotropic continuum-mechanical constitutive equation describing the overall mechanical behavior of skeletal muscle tissue. Since the multiscale model exhibits separable time scales, a special emphasis is placed on employing computationally efficient staggered solution schemes. Further, the implementation builds on the open-source software library OpenCMISS and uses state-of-the-art parallelization techniques taking advantage of the unique anatomical fiber architecture of skeletal muscles. OpenCMISS utilizes standardized data structures for geometrical aspects (FieldML) and cellular models (CellML). Both standards are designed to allow for a maximum flexibility, reproducibility, and extensibility. The results demonstrate the model's capability of simulating different aspects of nonisometric muscle contraction and efficiently simulating the chemoelectromechanical behavior in complex skeletal muscles such as the tibialis anterior muscle.","2013","2025-04-25 15:31:09","2025-04-25 15:31:09","","","","","2013","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Central to the automation of these systems is the early detection of named entities, a task that is foundational yet fraught with challenges due to the need for domain-specific expert annotations amid a backdrop of specialized terminologies, making the process both costly and complex. In response to this challenge, our paper presents an innovative named entity recognition (NER) framework (https://github. com/NeuralSentinel/DistALANER) tailored for the open-source software domain. Our method stands out by employing a distantly supervised, two-step annotation process that cleverly exploits language heuristics, bespoke lookup tables, external knowledge bases, and an active learning model. This multifaceted strategy not only elevates model performance but also addresses the critical hurdles of high costs and the dearth of expert annotators.

Researchers have studied a wide variety of motivations behind individuals' participation in OSS communities. In this study, we build upon the framework, rooted in self-deterministic and social practice theories, proposed by von Krogh et al. (2012) and develop a model of OSS contribution likelihood. We empirically validate the model with a large dataset from 2017 GitHub Open Source Survey that includes over 5,500 randomly selected OSS developers. Results indicate that short-term and/or tangible motivations (carrots) and long-term, value-based factors (rainbows) influence OSS developers' contribution likelihood. However, carrots are relatively more important. Further, we find that as internal self-efficacy increases, effect of OSS hiring behind contribution to OSS decreases.

Quantum Monte Carlo methods are a promising avenue of development as their core algorithm exhibits a number of favorable properties: it is highly parallel and scales favorably with the considered system size, with an accuracy that is limited only by the choice of the wave function Ansatz. The recently introduced machine-learned parametrizations of quantum Monte Carlo Ansatze rely on the efficiency of neural networks as universal function approximators to achieve state of the art accuracy on a variety of molecular systems. With interest in the field growing rapidly, there is a clear need for easy to use, modular, and extendable software libraries facilitating the development and adoption of this new class of methods. In this contribution, the DEEPQMC program package is introduced, in an attempt to provide a common framework for future investigations by unifying many of the currently available deep-learning quantum Monte Carlo architectures. Furthermore, the manuscript provides a brief introduction to the methodology of variational quantum Monte Carlo in real space, highlights some technical challenges of optimizing neural network wave functions, and presents example black-box applications of the program package. We thereby intend to make this novel field accessible to a broader class of practitioners from both the quantum chemistry and the machine learning communities.","2023-09-07","2025-04-25 15:31:09","2025-04-25 15:31:09","","","","9","159","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These organizations are voluntary in nature and rely on contributions from members to achieve their objectives. Examples include the Linux operating system and other FOSS projects, political movements, churches and religious groups, Habitat for Humanity, and similar charitable organizations. In this paper, we consider a world containing agents with heterogeneous abilities who may voluntarily choose to make effort contributions to one or more different public projects. Agents are motivated by a desire to be seen as significant contributors to important and valuable projects, the warm glow from the act of contributing, and a desire to directly enjoy the benefits of projects when complete. We find that contributions from others can be either strategic complements or substitutes. We show that Nash equilibria exist and study how agents' abilities and project quality affect the equilibrium levels of contributions.","2010-08","2025-04-25 15:31:09","2025-04-25 15:31:09","","665-689","","4","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At present, however, it still lacks a powerful, easy-to-use, and user-friendly professional software concerning generation and assessment of digital speckle pattern. Researchers have to reimplement the generation algorithms in literature by themselves, which is time-consuming and error-prone. This paper reports a free and open-source software, Glare, for generation and assessment of digital speckle pattern. Glare has functions including generating speckle patterns, rendering deformed images, assessing pattern quality, and presenting pattern recommendations: Glare can generate ellipse, polygon, and Gaussian speckle patterns; can render deformed images with underlying deformation fields of translation, stretch/compression, rotation, sinusoidal deformation, Gaussian deformation, and Portevin-Le Chatelier band deformation; can calculate key pattern quality assessment parameters such as speckle coverage, speckle size, systematic error, and random error; can produce optimized speckle pattern in form of vector image. The software realizes real-time deformed image rendering with the aid of fast initial value estimation algorithm for backward mapping and pattern pre-rendering technique, and improves the computational efficiency of sum of square of subset intensity gradients by integral image method. In general, the software can be used not only for scientific research and engineering applications in digital image correlation community but also for education of experimental mechanics, and therefore has broad prospects.","2022-01","2025-04-25 15:31:09","2025-04-25 15:31:09","","","","","148","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In biology, these systems have a direct relation to critical processes ranging from the movement of actin or assembly of viruses at cellular interfaces to the growth of amyloid plaques in neuro-degenerative diseases. In technology and applied sciences, synthetic macromolecules or fibrous objects such as carbon nanotubes are involved in countless applications. Accessing their intrinsic properties at the single molecule level, such as their molecular conformations or intrinsic stiffness, is central to the understanding of these systems, their properties, and the design of related applications. In this Perspective we introduce FiberApp a new tracking and analysis software based on a cascade of algorithms describing structural and topological features of objects characterized by a very high length-to-width aspect ratio, generally described as “fiber-like objects”. The program operates on images from any microscopic source (atomic force or transmission electron microscopy, optical, fluorescence, confocal, etc.), acquiring the spatial coordinates of objects by a semiautomated tracking procedure based on A* pathfinding algorithm followed by the application of active contour models and generating virtually any statistical, topological, and graphical output derivable from these coordinates. Demonstrative features of the software include statistical polymer physics analysis of fiber conformations, height, bond and pair correlation functions, mean-squared end-to-end distance and midpoint displacement, 2D order parameter, excess kurtosis, fractal exponent, height profile and its discrete Fourier transform, orientation, length, height, curvature, and kink angle distributions, providing an unprecedented structural description of filamentous synthetic and biological objects.","2015-03-10","2025-04-25 15:31:10","2025-04-25 15:31:10","","1269-1280","","5","48","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In Indonesia alone, 25% of South East Asia's mangroves are at a risk. The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was “Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang” held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes. Field work activity conducted and confirmed the changes that occurred in the study areas. Our study shows that all of the two districts exhibit successfulness of the plantation program. Ground truth survey confirmed that the successfulness of the plantation program is due to the participation of communities in the area of study. This study also shows that by using open source software and freely available satellite images, the fast, robust, and reliable data as an initial step to monitor both short-term and long-term plantation program can be collected effectively and inexpensively.","2017-08","2025-04-25 15:31:10","2025-04-25 15:31:10","","251-259","","3","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.","2001-10","2025-04-25 15:31:10","2025-04-25 15:31:10","","277-304","","4","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Taking imatinib (IMA) as an example, we developed an efficient workflow to describe IMA biodegradation with activated sludge (AS) from wastewater treatment plants (WWTP). IMA is a cytostatic pharmaceutical; a selective tyrosine kinase inhibitor used to treat chronic myeloid leukemia. Its reported ecotoxic, endocrine and genotoxic effects imply high risk for aquatic wildlife and human health, however its fate in the environment is not yet well known. The study was conducted in a batch biotransformation setup, at two AS concentration levels and in presence and absence of carbon source. Degradation profiles and formation of IMA transformation products (TPs) were investigated using UHPLC-QqOrbitrap-MS/MS which showed that IMA is readily biodegradable. TPs were determined using multivariate statistical analysis. Eight TPs were determined and tentatively identified, six of them for first time. Hydrolysis of amide bond, oxidation, demethylation, deamination, acetylation and succinylation are proposed as major biodegradation pathways. TP235, the product of amide bond hydrolysis, was detected and quantified in actual wastewaters, at levels around 1 ng/L. This calls for more studies on the environmental fate of IMA in order to properly asses the environmental risk and hazard associated to IMA and its TPs. (c) 2021 The Authors.

Most studies, based on a popular FLOSS repository (SourceForge). have concluded that the vast majority of projects are failures. This Study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities ire formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine.

Many individuals and organizations have purchased consumer-grade UAVs, and commonly acquire aerial photographs to map land cover. The resulting ultra-high-resolution (sub-decimeter-resolution) imagery has high information content, but automating the extraction of this information to create accurate, wall-to-wall land-cover maps is quite difficult. We introduce image-processing workflows that are based on open-source software and can be used to create land-cover maps from ultra-high-resolution aerial imagery. We compared four machine-learning workflows for classifying images. Two workflows were based on random forest algorithms. Of these, one used a pixel-by-pixel approach available in ilastik, and the other used image segments and was implemented with R and the Orfeo ToolBox. The other two workflows used fully connected neural networks and convolutional neural networks implemented with Nenetic. We applied the four workflows to aerial photographs acquired in the Great Basin (western USA) at flying heights of 10 m, 45 m and 90 m above ground level. Our focal cover type was cheatgrass (Bromus tectorum), a non-native invasive grass that changes regional fire dynamics. The most accurate workflow for classifying ultra-high-resolution imagery depends on diverse factors that are influenced by image resolution and land-cover characteristics, such as contrast, landscape patterns and the spectral texture of the land-cover types being classified. For our application, the ilastik workflow yielded the highest overall accuracy (0.82-0.89) as assessed by pixel-based accuracy.","2020-12","2025-04-25 15:31:10","2025-04-25 15:31:10","","487-497","","4, SI","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is important to deepen our understanding of spoofing attacks and develop resilient techniques to effectively combat this threat. Detecting and mitigating these attacks requires thorough testing, typically conducted in a laboratory environment through the establishment of a spoofing test-bed. The complexity, cost and resource demands of creating such a test-bed underscore the necessity of utilizing openly available datasets. To address this need, this paper introduces a new GNSS spoofing data repository from Finnish Geospatial Research Institute (FGI) named hereafter as `FGI-SpoofRepo'. This data repository consists of raw In-phase and Quadrature (I/Q) data of live recordings of GPS L1 C/A, Galileo E1, GPS L5, and Galileo E5a signals. These datasets encompass three distinct types of spoofing characteristics (synchronous, asynchronous, and meaconing), making them very useful example candidates of open data for testing the performance of any anti-spoofing techniques (be it detection or mitigation). The inclusion of live signals in multiple GNSS frequencies and the presence of cryptographic signatures in Galileo E1 signal make these datasets potential benchmarks for assessing the resilience performance of multi-frequency multi-constellation receivers. The analysis of the datasets is carried out with an open-source MATLAB-based software-defined receiver, FGI-GSRx. An updated version of FGI-GSRx, equipped with the necessary modifications for processing and analyzing the new datasets, is released alongside the datasets. Therefore, the GNSS research community can utilize the open-source FGI-GSRx or any third-party SDR to process the publicly available raw I/Q data for implementation, testing and validation of any new anti-spoofing technique. The results show that time-synchronous spoofing seamlessly takes over positioning solution, while time-asynchronous spoofing acts as noise or in some cases, completely prevent the receiver from providing a positioning solution. Signal re-acquisition during an ongoing spoofing attack (cold start), the receiver tends to lock onto the spoofing signal with the highest peak, posing a potential threat to GNSS receivers without assisted information. Overall, this research aims to advance the understanding of complex spoofing attacks on GNSS signals, providing insight into enhancing resilience in navigation systems.","2024-10","2025-04-25 15:31:10","2025-04-25 15:31:10","","","","4","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This perspective implicitly assumes that accessed network knowledge automatically gets absorbed and transferred to projects, so that building more and deeper network connections is beneficial: Drawing from an absorptive capacity perspective, this research challenges such conventional wisdom, arguing instead that the benefits depend on a project's absorptive capacity. Network connections provide access to external knowledge in the community; the absorption and transfer of this new knowledge require appropriate internal knowledge and developer roles. With longitudinal data collected from 4,518 open source software development projects hosted at Source-Forge, the authors show that knowledge breadth (depth) helps with the absorption of external knowledge achieved from network depth (breadth), but it inhibits the absorption of external knowledge obtained from network breadth (depth). Further, developer roles (e.g., bridge members, role diversity) can mitigate the negative consequences of suboptimal combinations and facilitate effective transfers of absorbed external knowledge across and within projects. These findings provide important theoretical and managerial implications for managing network connections, knowledge, and developer roles in open source software communities.","2020-12","2025-04-25 15:31:11","2025-04-25 15:31:11","","1651-1678","","4","44","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are-on average-more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect.

Different acquisition modes, such as whole-cell patch-clamp recordings in the current or voltage clamp configuration, capacitance measurements or single channel recordings from cultured cells as well as acute brain slices are routinely performed for these purposes. Nevertheless, multipurpose transparent and adaptable software tools to perform reproducible state-of-the-art analysis of multiple experiment types and to manage larger sets of experimental data are currently unavailable. Methods: Biophysical Essentials (BPE) was developed as an open-source full stack python software for transparent and reproducible analysis of electrophysiological recordings. For validation, BPE results were compared with manually analyzed single-cell patch-clamp data acquired from a human in vitro nociceptor-model and mouse dorsal root ganglia neurons. Results: While initially designed to improve time consuming and repetitive analysis steps, BPE was further optimized as a technical software solution for entire workflow processing including data acquisition, data preprocessing, normalization and visualization and of single recordings up to stacked calculations and statistics of multiple experiments. BPE can operate with different file formats from different amplifier systems and producers. An in-process database logs all analysis steps reproducible review and serves as a central storage point for recordings. Statistical testing as well as advanced analysis functions like Boltzmann-fitting and dimensional reduction methods further support the researchers' needs in projects involving electrophysiology techniques. Conclusions: BPE extends beyond available patch-clamp specific, open source - and commercial analysis tools in particular because of reproducible and sharable analysis workflows. BPE enables full analysis from raw data acquisition to publication ready result visualizations - all within one single program. Thereby, BPE significantly enhances transparency in the analytical process of patch-clamp data analysis. BPEs function scope is completely accessible through an easy-to-use graphical user interface eliminating the need for programing language proficiency as required by many community patch-clamp analysis frameworks and algorithms.","2024-10","2025-04-25 15:31:11","2025-04-25 15:31:11","","","","","255","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Free open-source software tools for documenting, analyzing, visualizing, and sharing using electronic notebooks","JOURNAL OF NEUROPHYSIOLOGY","","0022-3077","10.1152/jn.00137.2016","","Neurophysiology requires an extensive workflow of information analysis routines, which often includes incompatible proprietary software, introducing limitations based on financial costs, transfer of data between platforms, and the ability to share. An ecosystem of free open-source software exists to fill these gaps, including thousands of analysis and plotting packages written in Python and R, which can be implemented in a sharable and reproducible format, such as the Jupyter electronic notebook. This tool chain can largely replace current routines by importing data, producing analyses, and generating publication-quality graphics. An electronic notebook like Jupyter allows these analyses, along with documentation of procedures, to display locally or remotely in an internet browser, which can be saved as an HTML, PDF, or other file format for sharing with team members and the scientific community. The present report illustrates these methods using data from electrophysiological recordings of the musk shrew vagus-a model system to investigate gut-brain communication, for example, in cancer chemotherapy-induced emesis. We show methods for spike sorting (including statistical validation), spike train analysis, and analysis of compound action potentials in notebooks. Raw data and code are available from notebooks in data supplements or from an executable online version, which replicates all analyses without installing software-an implementation of reproducible research. This demonstrates the promise of combining disparate analyses into one platform, along with the ease of sharing this work. In an age of diverse, high-throughput computational workflows, this methodology can increase efficiency, transparency, and the collaborative potential of neurophysiological research.","2016-08","2025-04-25 15:31:11","2025-04-25 15:31:11","","252-262","","2","116","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage. The empirical investigation in this paper shows that the switching points of stages have meaningful associations with the release dates.","2014","2025-04-25 15:31:11","2025-04-25 15:31:11","","207-212","","","","","","","EUROMICRO Conference Proceedings","","","","Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro","","","","","","","","","ISSN: 1089-6503","","","","","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

LAMB addresses critical gaps in existing educational AI solutions by providing a framework specifically designed for the unique requirements of the education sector. It introduces novel features, including a modular architecture for seamless integration of AI assistants into existing LMS platforms and an intuitive interface for educators to create custom AI assistants without coding skills. Unlike existing AI tools in education, LAMB provides a comprehensive framework that addresses privacy concerns, ensures alignment with institutional policies, and promotes using authoritative sources. LAMB leverages the capabilities of large language models and associated generative artificial intelligence technologies to create generative intelligent learning assistants that enhance educational experiences by providing personalized learning support based on clear directions and authoritative fonts of information. Key features of LAMB include its modular architecture, which supports prompt engineering, retrieval-augmented generation, and the creation of extensive knowledge bases from diverse educational content, including video sources. The development and deployment of LAMB were iteratively refined using a minimum viable product approach, exemplified by the learning assistant: “Macroeconomics Study Coach,” which effectively integrated lecture transcriptions and other course materials to support student inquiries. Initial validations in various educational settings demonstrate the potential that learning assistants created with LAMB have to enhance teaching methodologies, increase student engagement, and provide personalized learning experiences. The system's usability, scalability, security, and interoperability with existing LMS platforms make it a robust solution for integrating artificial intelligence into educational environments. LAMB's open-source nature encourages collaboration and innovation among educators, researchers, and developers, fostering a community dedicated to advancing the role of artificial intelligence in education. This paper outlines the system architecture, implementation details, use cases, and the significant benefits and challenges encountered, offering valuable insights for future developments in artificial intelligence assistants for any sector.","2025-03","2025-04-25 15:31:11","2025-04-25 15:31:11","","","","","92","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In doing so, it offers new insights into the association between open innovation and diversification. We rely on arguments inspired by the literature and evidence collected through interviews with OSS SMEs' top managers to investigate factors that favor or hinder within-industry diversification. First, in line with the mainstream diversification literature, we focus attention on the role of firm size. Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products. Furthermore, we provide preliminary evidence that the practice of authorizing firm programmers to contribute autonomously to OSS projects of their own choice during working hours may be positively associated to within-industry diversification only if OSS SMEs possess adequate internal technological resources.

This paper seeks to broaden the research on virtual communities by applying the theory of competency rallying (TCR) in a longitudinal manner to examine the impact of task identification, task assignment, task execution and task management on user interest in open source software (OSS) projects defined by popularity and communication. The aim of this paper is: (I) re-conceptualizing the concept of user interest and broadening our understanding of user interest by incorporating users' post-usage behaviors, (2) examining the effect of various tasks involved in an OSS project's key processes of defect-fixing and feature-enhancement on user interest. The current study found that project popularity is positively influenced by task assignment, task execution and task management. Additionally, user communication was found to be positively impacted by task identification and task execution. The data collected from 1178 OSS projects in a longitudinal manner (at 3 time points over a period of 16 months) confirmed the expectations from TCR and also demonstrated that over time the effects that development of competencies and managing short term cooperative work have on project success might increase, while the impact of identifying market needs and marshalling competencies may not significantly change.

Since then, it has become practically essential for identifying bacteria in microbiological diagnostic laboratories. In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from. MSProfileR has been developed in the R environment and offers a user-friendly web interface using the R Shiny framework. It is available on Microsoft Windows as a web browser application by simple navigation using the link of the package on Github v.3.10.0. MSProfileR is therefore accessible to non-computer specialists and is freely available to the scientific community. We evaluated MSProfileR using two datasets including exclusively MS spectra from arthropods. In addition to coherent sample classification, outlier MS spectra were detected in each dataset confirming the value of MSProfileR.","2024-06","2025-04-25 15:31:11","2025-04-25 15:31:11","","","","2","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The well-being of a FOSS project depends on the turning of project newcomers into `good contributors' that is to say into individuals that substantially contribute to the project - but also that perform citizenship behaviors that protect and nurture its community. This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness.

Companies must govern their FLOSS use to avoid potential risks to their intellectual property resulting from the use of FLOSS components. A particular challenge is license compliance. To manage the complexity of license compliance, companies should use tools and well-defined processes to perform these tasks time and cost efficiently. This paper investigates and presents common industry requirements for FLOSS governance tools, followed by an evaluation of the suggested requirements by matching them with the features of existing tools. We chose 10 industry leading companies through polar theoretical sampling and interviewed their FLOSS governance experts to derive a theory of industry needs and requirements for tooling. We then analyzed the features of a governance tools sample and used this analysis to evaluate two categories of our theory: FLOSS license scanning and FLOSS in product bills of materials. The result is a list of FLOSS governance requirements based on our qualitative study of the industry, evaluated using the existing governance tool features.

This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success. We also show that when development environment difference is moderate, the impact of role diversity is the most positive. We present the implications of these findings for theory and practice.","2018-09","2025-04-25 15:31:12","2025-04-25 15:31:12","","237-256","","3","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using the concept of episodic volunteering (EV) from the general volunteering literature, we derive a model consisting of five key constructs that we hypothesize affect episodic volunteers' retention in FLOSS communities. To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated. Based on our findings, we offer suggestions for projects to incorporate and manage episodic volunteers, so as to better leverage this type of contributors and potentially improve projects' sustainability.","2019","2025-04-25 15:31:12","2025-04-25 15:31:12","","948-959","","","","","","","International Conference on Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE Comp Soc, Tech Comm Software Engn","","","","","","","","","ISSN: 0270-5257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the “institutional design” of the ASF could aid in producing the OSS public good by providing services that projects require.","2022","2025-04-25 15:31:12","2025-04-25 15:31:12","","64-77","","1","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some modalities, such as mammography, contain highly standardized imaging. In contrast, breast ultrasound imaging (BUS) can contain many irregularities not indicated by scan metadata, such as enhanced scan modes, sonographer annotations, or additional views. We present an open-source software solution for automatically processing clinical BUS datasets. The algorithm performs BUS scan filtering (flagging of invalid and non-B-mode scans), cleaning (dual-view scan detection, scan area cropping, and caliper detection), and knowledge extraction (BI-RADS Labeling and Measurement fields) from sonographer annotations. Its modular design enables users to adapt it to new settings. Experiments on an internal testing dataset of 430 clinical BUS images achieve >95% sensitivity and >98% specificity in detecting every type of text annotation, >98% sensitivity and specificity in detecting scans with blood flow highlighting, alternative scan modes, or invalid scans. A case study on a completely external, public dataset of BUS scans found that BUSClean identified text annotations and scans with blood flow highlighting with 88.6% and 90.9% sensitivity and 98.3% and 99.9% specificity, respectively. Adaptation of the lesion caliper detection method to account for a type of caliper specific to the case study demonstrates the intended use of BUSClean in new data distributions and improved performance in lesion caliper detection from 43.3% and 93.3% out-of-the-box to 92.1% and 92.3% sensitivity and specificity, respectively.

The morphometric quantification of these networks is essential to study the cellular phenotype. Commonly, the quantitative measurements are performed on 2D projections of the image stack, resulting in the loss of information in the third dimension. Currently available 3D image analysis tools rely on manual interactions with the software and are therefore not feasible for large datasets. Findings Here we present Qiber3D, an open-source image processing toolkit. The software package includes the essential image analysis procedures required for image processing, from the raw image to the quantified data. Optional pre-processing steps can be switched on/off depending on the input data to allow for analyzing networks from a variety of sources. Two reconstruction algorithms are offered to meet the requirements for a wide range of network types. Furthermore, Qiber3D's rendering capabilities enable the user to inspect each step of the image analysis process interactively to ensure the creation of an optimal workflow for each application. Conclusions Qiber3D is implemented as a Python package, and its source code is freely available at https://github.com/theia-dev/Qiber3D. The toolkit was designed using a building block principle to enable the analysis of a variety of structures, such as vascular networks, neuronal structures, or scaffolds from numerous input formats. While Qiber3D can be used interactively in the Python console, it is aimed at unsupervised automation to process large image datasets efficiently.","2022","2025-04-25 15:31:12","2025-04-25 15:31:12","","","","","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Free and open-source software (FOSS) presents a viable solution for facilitating the transfer of digital archives for permanent preservation. Despite the existence of FOSS policy in South Africa, the public sector has yet to fully use it to engage in the development and implementation of products for records management and archive preservation using open-source software. This study aims to explore the ingestion of digital archives into an approved long-term storage system through FOSS in South Africa with the view of developing a framework.Design/methodology/approachThe study adopted a qualitative research approach to collect data through interviews with purposively selected participants (records managers, archivists and IT officials) from national government departments that have implemented records management systems for digital curation of archives, as well as the National Archives and Records Services of South Africa (NARSSA), which regulates archives and records management, and the State Information Technology Agency, which regulates information technology in government.FindingsThe findings of the study suggest that the systematic transfer of digital materials from public entities to NARSSA, as required by statute, has not taken place.Research limitations/implicationsThe study specifically targeted national government departments that have implemented digital archives and records management systems.

This increase in digital recordings necessitates an increase in high-throughput methods of analysis for researchers. Specifically, there is a need in the community for open-source methods that are tailored to recordings of varying qualities and from multiple species collected in nature. We developed Chipper, a Python-based software to semi-automate both the segmentation of acoustic signals and the subsequent analysis of their frequencies and durations. For avian recordings, we provide widgets to best determine appropriate thresholds for noise and syllable similarity, which aid in calculating note measurements and determining song syntax. In addition, we generated a set of synthetic songs with various levels of background noise to test Chipper's accuracy, repeatability and reproducibility. Chipper provides an effective way to quickly generate quantitative, reproducible measures of birdsong. The cross-platform graphical user interface allows the user to adjust parameters and visualize the resulting spectrogram and signal segmentation, providing a simplified method for analysing field recordings. Chipper streamlines the processing of audio recordings with multiple user-friendly tools and is optimized for multiple species and varying recording qualities. Ultimately, Chipper supports the use of citizen-science data and increases the feasibility of large-scale multi-species birdsong studies.","2020-04","2025-04-25 15:31:12","2025-04-25 15:31:12","","524-531","","4","11","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a “safety net” for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and “living” design documentation. Rapid-cycle development or “agile” methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as “executable requirements.” Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the “executable requirements” are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.","2018-06","2025-04-25 15:31:12","2025-04-25 15:31:12","","80-90","","2","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Embedded functionality handles erroneous data point detection and removal, m tier identification through the use of clustering techniques, linking logbook and VMS data together in order to distinguish fishing from other activities, provide high-resolution maps of both fishing effort and -landings, interpolate vessel tracks, calculate indicators of fishing impact as listed under the Data Collection Framework at different spatio-temporal scales. Finally data can be transformed into other existing formats, for example to populate regional databases like FishFrame. This paper describes workflow examples of these features while online material allows a head start to perform these analyses. This software incorporates state-of-the art VMS and logbook analysing methods standardizing the process towards obtaining pan-European, or even worldwide indicators of fishing distribution and impact as required for spatial planning.

Analyzing these deformations allows a better understanding of the causes and mechanisms of the events. By using sub-pixel correlation on before- and after-event ortho-images obtained from high resolution satellite images it is possible to compute the displacement field with high planimetric resolution. In this paper, we focus on measuring the ground displacements due to seismotectonic events. The three sub-pixel correlators used are: COSI-Corr - developed by Caltech, a free, closed-source correlator, dependent on commercial software (ENVI) and widely used by the geoscience community for measuring ground displacement; Medicis - developed by CNES, also a closed-source correlator capable of measuring this type of deformation; and MicMac - developed by IGN, the free open-source correlator we study and tune for measuring fine ground displacements. We measured horizontal ground deformation using these three correlators on SPOT images in three study cases: the 2001 Kokoxili earthquake, the 2005 dyke intrusion in the Afar depression and the 2008 Yutian earthquake.

First, we have to model these signatures. In Lapierre et al. (2006), Lapierre et al. (2007) [3,4], we proposed an infrared (IR) ship signature simulation software (OSMOSIS) that can manage parametric emissivity. OSMOSIS comprises a smart computation time and memory management. Evaluating the effectiveness of an IR signature reduction method implies simulating the evolution of the IR signature with time. This requires a huge computation time. In this paper, we propose a novel hierarchical meshing strategy leading to an important reduction of the computation time. The time complexity of the algorithm is shown to be O(root N), where N is the requested number of facets of the mesh of the ship's surface. Then, we validate OSMOSIS on temperature measurements performed on an “L-shape” object. (C) 2009 Elsevier B.V.

Nowadays, open-source software is a viable substitute for proprietary software. This work presents a CFD analysis of the hydrodynamics of a finned tube using the OpenFOAM and SALOME Meca platforms. The results are compared with experimental data and CFD using the commercial software Fluent, both previously reported in the open literature. This work studies the fluid flow pattern around a tube with six 45-degree-angled fins, and the working fluid, air, is considered as an incompressible fluid. Special attention is paid to calculating the pressure coefficient distribution for the internal and external surfaces of the inclined fins. Open-source platforms allow researchers to visualize how the airflow interacts with the cylinder and the fin surfaces to form a fluid structure, formerly known as a horseshoe vortex system. The findings of the analysis of flow dynamics in the channel between inclined fins and in the wake help explain the results obtained in experimental tests and are relevant for the configuration of a bank of tubes with inclined fins.","2022-08","2025-04-25 15:31:13","2025-04-25 15:31:13","","","","8","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to describe the software architecture. Design/methodology/approach - The DEM chosen uses position, orientation, velocity and angular velocity as independent variables of simulated particles which are subject to explicit leapfrog time-integration scheme (Lagrangian method). The three-dimensional dynamics equations based on the classical Newtonian approach for the second law of motion are used. The track of forces and moments acting on each particle is kept at every time step. Contact forces depend on the particle geometry overlap and material properties. The normal, tangential and moment components of interaction force are included. Findings - An effort is undertaken to extract the underlying object oriented abstractions in the DEM. These abstractions are implemented in C++, conform to object oriented design principles and use design patterns. Based on that, a software framework is developed in which the abstractions provide the interface where the modelling methods can be plugged-in. Originality/value - The resulting YADE-OPEN DEM framework is designed in a generic way which provides great flexibility when adding new scientific simulation code. Some of the advantages are that numerous simulation methods can be coupled within the same framework while plug-ins can import data from other software. In addition, this promotes code improvement through open-source development and allows feedback from the community. However implementing such models requires that one adheres to the framework design and the YADE framework is a new emerging software.

The research is aimed at exploring how factors such as perceived ease of use (PEOU), compatibility, perceived risk, security, and cost-effectiveness influence OSS adoption. Using a quantitative research methodology, data was collected from 272 university decision-makers and analysed using Smart PLS 4. The results of the study indicate that factors such as PEOU, compatibility, perceived risk, security, and cost-effectiveness have a significant positive influence on the adoption of OSS.

As knowledge-based firms, COSS companies' success depends heavily on the interplay among intangible resources such as human capital, relational capital, structural capital, and software quality. To observe these relationships, we conducted a hypothesis-testing questionnaire-type survey involving 200 software development experts and professionals working at 60 multinational COSS companies. Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model. Therefore, COSS companies may need to prioritize software quality as it is the most critical variable impacting the success of COSS companies.","2022","2025-04-25 15:31:13","2025-04-25 15:31:13","","46490-46503","","","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to consider the effect of each software component on the reliability of an entire system under such open source software, we propose a new approach to software reliability assessment by creating a fusion of neural network and software reliability growth model based on stochastic differential equations. Also, we analyze actual software fault count data to show numerical examples of software reliability assessment for the open source software.","2007","2025-04-25 15:31:13","2025-04-25 15:31:13","","147+","","","","","","","","","","","Int Soc Sci & Appl Technol","","","","","","","","","","","","","","","Pham, H; Pham, H; Yamada, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

What we need to understand about this topic is on the process of producing software through cooperation of different efforts. Albeit many success reasons for these projects are inherently due to the application domain that the project develops, architectural and conceptual views of the code have to be considered as key factors when considering community efforts and joint decisions. In this work we focus our attention on what is perceived of a source code when investigating its structure. We do this considering that structure as a proxy for the conceptual architecture of the application. A metric is developed based on some current assumptions, and it is tested over a sample of Open Source projects. What is interesting to note, is that refactoring efforts are clearly visible when intended as reduction of complexity of source code. Our second observation is that, based on what an Open Source software currently does, i.e. its application domain, there's a threshold value that several projects tend to.","2004","2025-04-25 15:31:14","2025-04-25 15:31:14","","58-66","","","","","","","","","","","IEEE Comp Soc, TCSE; Nokia; TietoEnator; Tampere Univ Tech ol; Acad Finland; Reengineering Forum","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The analysis of past and current projects, governed by different organizations and communities, pointed out a variety of tasks that can be accomplished by citizens. In these studies, authors stressed suitability of smartphones for the fulfilment of various assignments given to citizens. Due to that, in this research, different smartphone applications for water quality monitoring were tested and analyzed. Despite the fact that many applications for water quality monitoring are freely available, none of them is open source.

However, the focus has primarily been on intra-project clones. Our work comprehensively investigates cross-project code clones in open-source software for Internet of Things (IoT) systems across multiple programming languages. This work addresses the prevalence of cross-project code clones in IoT systems and their impact on software maintainability. We collected 122 IoT system repositories in nine languages from GitHub and grouped them according to their primary functionality in IoT systems. We used MSCCD, a multilingual code clone detector to detect Type-3 code clones for each group. The results show that cross-project clones exist in more than 30% of the projects, particularly in communication-related functionalities. We tracked the historical evolution of these clones and classified them according to the revision history and changing trend of similarity. The results show that 95% cross-project clones are untouched. Moreover, clones with decreasing similarities were over 72%. Therefore, the same clone detector may no longer detect these clones. We also investigated whether these cross-project code clones lead to defect propagation by analyzing the commit message to determine the commits that fixed a defect. We identified nine defect propagation instances, of which seven remain unfixed. Our work contributes to understanding cross-project code clones, highlighting the importance of automated clone management tools for improving the quality and security of IoT system software to mitigate the risks associated with unresolved defects and inconsistencies in IoT software development.","2024","2025-04-25 15:31:14","2025-04-25 15:31:14","","179104-179118","","","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the context of applying open-source software, the differences in the numerical results due to different model parameters need to be investigated in detail. In this study, some benchmark problems have been solved with DualSPHysics to validate the estimation of wave impact pressure with violent breaking waves. We have demonstrated three main results: (i) as an alternative to the artificial viscosity traditionally used in DualSPHysics, a laminar viscosity model can also well reproduce the solutions to the existing benchmark problems in a violent flow field with the modified dynamic boundary condition; (ii) the dynamics of the gas phase is essential in the calculation of wave breaking with rapid gate opening; and (iii) if the density diffusion parameter is too large, the impact pressure may be underestimated. The practical contribution by this study is to find that DualSPHysics well reproduces complex breaking waves, including multi-phase gas-liquid flows, and that the wave impact pressure is accurate by comparison with existing experimental results. This allows us to understand the complex behavior of fluid-structure interactions in coastal engineering by means of DualSPHysics.","2021-10-02","2025-04-25 15:31:14","2025-04-25 15:31:14","","545-572","","4","63","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An increasing rate of urban growth and urban sprawl could induce changes in land use as well as land transformation. However, accurate and up-to-date information about LULC is required for providing better understanding and assessing the environmental consequences of such changes. In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80% and 80.40% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification. To summarize, ArcGIS and QGIS software are reliable to be used in the land cover classification.","2020","2025-04-25 15:31:14","2025-04-25 15:31:14","","","","","540","","","","IOP Conference Series-Earth and Environmental Science","","","","Inst Geospatial & Remote Sensing Malaysia; Univ Putra Malaysia; Sc & Technol Res Inst Def; Univ Teknologi Malaysia; Univ Utara Malaysia; Int Islam Univ Malaysia; Forest Res Inst Malaysia; GIS Innovat Sdn Bhd; GPS Lands M Sdn Bhd; IEEE Geoscience & Remote Sensing Soc, Malaysia Chapter","","","","","","","","","ISSN: 1755-1307","","","","","","Omar, H; Shariff, ARM; Sathyamoorthy, D; Mat, RC; Tarmidi, Z; Ismail, MH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community.

The influence of `digital sovereignty' in the EU's Cybersecurity Strategy on cybersecurity of open-source software","COMPUTER LAW & SECURITY REVIEW","","0267-3649","10.1016/j.clsr.2024.106078","","`Digital sovereignty' is the geopolitical mantra of the moment. A key agent of that policy shift, the European Union ('EU') has increasingly embraced `digital sovereignty' as both the ideological foundation and impetus for building its digital future in accordance with `European values and principles,' often driven by and intersecting with cybersecurity concerns as articulated in its 2020 Cybersecurity Strategy for the Digital Decade ('Strategy'). Yet it is impossible to consider cybersecurity without open-source software ('OSS'). Increasingly, the EU, USA and other Governments have recognised that fact in the wake of HeartBleed and Log4j incidents. OSS' decentralised governance and ubiquity, underpinning most software worldwide, may amplify vulnerabilities and adverse effects of cyberattacks, whilst its typically collaborative model of development and innovation often fosters valuable, open cybersecurity solutions. In navigating that policy tightrope of OSS as a double-edged sword for cybersecurity, the EU has adopted `closed' language of `digital sovereignty' that is ostensibly contrary to the `open' nature of OSS. That rhetorical duality is particularly pronounced since the EU described OSS as a tool for realising its `digital sovereignty,' in addition to policy support for `a global, open, interoperable cyberspace' alongside the pursuit of `digital sovereignty.' While there is a epistemic gap in understanding the relationship between the EU's rhetoric of `digital sovereignty' and reality, nascent studies indicate that it has a tangible effect on policy change in multiple digital spheres, generally furthering a degree of `control.' However, that relationship within the OSS cybersecurity context has underexplored and poorly understood, although that policy is a priority for the EU and may bear significant implications for OSS globally. Particularly analyzing the Cyber Resilience Act ('CRA') as key means for implementing the EU's Strategy and its first cybersecurity legislation that would comprehensively engage OSS if adopted by the Council, this article argues that the EU's desire to strengthening cybersecurity in OSS is generally welcome. Yet there is an ostensibly a disjunct between `digital sovereignty' that underpins that legislation and OSS cybersecurity, with too much control of OSS potentially proving counterproductive for EU cybersecurity. This paper illustrates that (i) it is imperative for the EU to address OSS cybersecurity; (ii) yet the lens of digital sovereignty is ostensibly a rough fit for that approach, considering OSS' philosophy and practice; and (iii) based on the CRA, EU's practice of translating `digital sovereignty' into policy change is mixed, leaving uncertain ramifications for OSS cybersecurity in the EU and beyond. On the one hand, it moves towards more `control' at least in determining definitional parameters and power dynamics with novel `stewardship' positions for certain OSS entities. That said, the EU generally seeks to leverage OSS to further their regional embrace of OSS rather than to exclude others. Ultimately, the EU has a valuable leadership opportunity to drive forward solutions to OSS cybersecurity in collaboration with others whilst avoiding fragmentation, keeping doors open in recognising that global challenges demand global solutions. That is in its enlightened self-interest.","2025-04","2025-04-25 15:31:14","2025-04-25 15:31:14","","","","","56","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person-environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity. We discuss the implications of our findings for research and practice.","2019-09","2025-04-25 15:31:14","2025-04-25 15:31:14","","951+","","3","43","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, obtaining Koc requires a significant amount of time and enormous expenditure. Thus, it is necessary to efficiently estimate Koc in the early stages of a chemical?s development. In this study, a quantitative structure-property relationship (QSPR) model was developed using calculated physicochemical properties and molecular descriptors with the OPEn structure-activity/property Relationship App (OPERA) and Mordred software using the largest available Koc dataset. Specifically, we compared the accuracies of the model using the light gradient boosted machine (LightGBM), a gradient boosting decision tree (GBDT) algorithm, with those of previous models. The experimental results suggested the potential to develop a QSPR model that will produce highly accurate Koc values using molecular descriptors and physicochemical properties. Unlike previous studies, the use of a combination of LightGBM, OPERA and Mordred enables the prediction of Koc for many chemicals with high accuracy. In this study, OPERA was used to calculate the physicochemical properties, and Mordred was used to calculate molecular descriptors. The wide range of chemicals covered by OPERA and Mordred enables the analysis of a diverse range of chemical compounds. We also report a method to tune the LightBGM program. The use of fast-processing software, such as LightGBM, enables parameter tuning of a method required to obtain best performance. Our research represents one of the few studies in the field of environmental chemistry to use LightGBM. Using physicochemical properties as well as molecular descriptors, we could develop highly accurate Koc prediction models when compared to prior studies. In addition, our QSPR models may be useful for preliminary environmental risk assessment without incurring significant costs during the early chemical developmental stage.","2021-05","2025-04-25 15:31:14","2025-04-25 15:31:14","","","","","196","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We then investigate the relationship of such behavior to what the formal policies prescribe, through their own governance priorities and how their members internalize them. Our findings indicate that a greater amount of policy over a governed topic doesn't elicit more governed activity on that topic, but does predict greater internalization by community members.

Each Competence Centre acts in its geographical region to increase the awareness of FLOSS and to better prepare the IT workforce for developing and using FLOSS based solutions. As of 2009, the process for Competence Centre creation is sustainable and reusable; guidelines for establishing proposals and opening new Competence Centres have been created, and promotion of Qualipso Competence Centres is done world wide from India to USA thanks to key initiatives such as the Open World Forum and the FLOSS Competence Centre Summit. This lecture will expose how these Competence Centres relate to each other, which governance model is used and, based on existing experiences, will describe how they currently operate in Europe and Brazil and what is planned in Italy, Belgium, Japan, and China for 2010.","2010","2025-04-25 15:31:15","2025-04-25 15:31:15","","348-353","","","319","","","","IFIP Advances in Information and Communication Technology","","","","Int Federat Informat Proc Work Grp 2 13","","","","","","","","","ISSN: 1868-4238","","","","","","Agerfalk, P; Boldyreff, C; GonzalezBarahona, JM; Madey, GR; Noll, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Metabolites are generally annotated with various database or structure based identifiers. Metabolite annotations in metabolic reconstructions may be incorrect or incomplete and thus need to be updated prior to their use. Genome-scale metabolic reconstructions generally include hundreds of metabolites. Manually updating annotations is therefore highly laborious. This prompted us to look for open-source software applications that could facilitate automatic updating of annotations by mapping between available metabolite identifiers. We identified three applications developed for the metabolomics and chemical informatics communities as potential solutions. The applications were MetMask, the Chemical Translation System, and UniChem. The first implements a “metabolite masking” strategy for mapping between identifiers whereas the latter two implement different versions of an InChI based strategy. Here we evaluated the suitability of these applications for the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We applied the best suited application to updating identifiers in Recon 2, the latest reconstruction of human metabolism. Results: All three applications enabled partially automatic updating of metabolite identifiers, but significant manual effort was still required to fully update identifiers. We were able to reduce this manual effort by searching for new identifiers using multiple types of information about metabolites. When multiple types of information were combined, the Chemical Translation System enabled us to update over 3,500 metabolite identifiers in Recon 2. All but approximately 200 identifiers were updated automatically. Conclusions: We found that an InChI based application such as the Chemical Translation System was better suited to the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We identified several features, however, that could be added to such an application in order to tailor it to this task.","2014-01-27","2025-04-25 15:31:15","2025-04-25 15:31:15","","","","","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This in turn is influenced by three types of social capital - relational capital, cognitive capital and structural capital. In addition, this study also examines two moderating effects - the impact of technical complexity on the relationship between cognitive capital and expertise integration, and of task interdependence on the relationship between expertise integration and task completion. Through a field survey of 160 OSS members from five Taiwanese communities, there is support for some of the proposed hypotheses. Both reciprocity and centrality affect expertise integration as expected, but the influence of commitment and cognitive capital (including expertise and tenure) on expertise integration is not significant. Finally, expertise integration affects both team size and team effort, which in turn jointly influence task completion. This research contributes to advancing theoretical understanding of the effectiveness of free OSS development as well as providing OSS practitioners with insight into how to leverage social capital for improving the performance of OSS development.","2011-03","2025-04-25 15:31:15","2025-04-25 15:31:15","","195-219","","2","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

FLOSS communities and products have been studied as complementary to proprietary software companies and products. In this paper we propone a business model for the software market, and in particular we analyze the competition between proprietary software firms and FLOSS firms. Our software market is a system where each agent is independent of each other in the choice about buying or selling software products or services. The proposed work aims to analyze the influence of FLOSS firms producing both software and services in vertical software markets, nowadays mostly dominated by large proprietary firms. The findings show that FLOSS firms are able to compete with proprietary firms, though in the end a monopoly or oligopoly of the latters emerges. The ousted FLOSS firms, however, survive longer than proprietary ones, when these are not able to compete in the market.","2011","2025-04-25 15:31:15","2025-04-25 15:31:15","","56-69","","","80","","","","Lecture Notes in Business Information Processing","","","","","","","","","","","","","ISSN: 1865-1348","","","","","","Regnell, B; VanDeWeerd, I; DeTroyer, O","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ability of the variometric approach to detect short-term dynamic behaviors in real-time mode in applications such as Global Navigation Satellite Systems (GNSS)-seismology and structural health monitoring is demonstrated, the demand for open-source VA software is increasing. However, open-source software that is capable of VA processing in real-time mode based on single- and dual-frequency multi-GNSS observations is scarce. In view of this fact, we have developed an open-source VA processing software called PPPH-VA that can evaluate single- and dual-frequency multi-GNSS observations in real-time mode. PPPH-VA is developed in the MATLAB environment, and it can simultaneously process GPS, GLONASS, Galileo, BeiDou-2, and BeiDou-3 data with the VA technique in real-time mode, employing both single- and dual-frequency observations. We evaluated PPPH-VA using shake table experiments based on real data, and the results demonstrate that it provides high accuracy in terms of detection of dynamic displacements. Toolbox can successfully detect the dominant frequencies of short-term dynamic behaviors and is capable of determining the amplitude values corresponding to the peak frequency at the sub-mm level. Moreover, in the time domain, it can obtain dynamic behaviors with an accuracy of millimeters.","2024-01","2025-04-25 15:31:15","2025-04-25 15:31:15","","","","1","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The objective of our work is twofold. First, our research aims to understand and model the dynamics of OSS design that take place in mailing list exchanges. Second, our more long term objective is to develop tools to assist OSS developers to extract and reconstruct design relevant information from previous discussions. We show how quotation practices can be used to locate design relevant data in discussion archives. OSS developers use quotation as a mechanism to maintain the discursive context. To retrace thematic coherence in the online discussions of a major OSS project, Python, we follow how messages are linked through quotation practices. We compare our quotation-based analysis with a more conventional, thread-based analysis of the (reply-to) links between messages. The advantages of a quotation-based analysis over a thread-based analysis are outlined. Our approach provides a means to analyze argumentation and design rationales and promises a novel means to discover design relevant information in the archives of online discussions. Our analysis reveals also the links between the social structure and elements in the discussion space and how it shapes influence in the design process.","2005","2025-04-25 15:31:15","2025-04-25 15:31:15","","301-320","","","","","","","","","","","Convivio; Univ Milano Bicocca, Dept Informat, Syst & Commun; Univ Milano","","","","","","","","","","","","","","","VandenBesselaar, P; DeMichelis, G; Preece, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement.

Hence, many models dealing with the calibration of ductile damage of materials have already been developed to predict failure initiation. Nevertheless, the challenge remains in obtaining an accurate representation of the fracture growth. Herein, an element deletion algorithm is developed and implemented into finite element open-source software. The deleted elements are replaced by new cells made of a virtual low-stiffness material. To better visualize the failure progression, the final model excludes these virtual cells from the representation. The functionality of the algorithm is tested through a series of two-dimensional simulations on three different geometries with a well-known behavior under uniaxial tension. Moreover, the failure response of a three-dimensional lattice structure is numerically investigated and compared against experimental data. The results of the two-dimensional simulations showed the capability of the algorithm to predict the onset of failure, crack nucleation, and fracture growth. Similarly, the onset and the initial fracture region were accurately captured in the three-dimensional case, with some convergence issues that prevent the visualization of the fracture growth. Overall, the results are encouraging, and the algorithm can be improved to introduce other computational functionalities.","2023-01","2025-04-25 15:31:15","2025-04-25 15:31:15","","","","1","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, proprietary packages seem still to be the first choice for herpetologists, thus involving non negligible costs for GIS technology adoption. Additional costs arise from environmental data, which are usually expensive, worsening in the case of large study areas.

Taking perspectives from both melodic recall and singing accuracy literature, we present results from two online experiments (N = 247; N = 910). On-the-fly audio transcription is produced via a probabilistic algorithm and scored via latent variable approaches. Measures of the ability to sing long notes indicate a three-dimensional principal components analysis solution representing pitch accuracy, pitch volatility and changes in pitch stability (proportion variance explained: 35%; 33%; 32%). For melody singing, a mixed-effects model uses features of melodic structure (e.g., tonality, melody length) to predict overall sung melodic recall performance via a composite score [R(2)c = .42; R(2)m = .16]. Additionally, two separate mixed-effects models were constructed to explain performance in singing back melodies in a rhythmic [R(2)c = .42; R(2)m = .13] and an arhythmic [R(2)c = .38; R(2)m = .11] condition. Results showed that the yielded SAA melodic scores are significantly associated with previously described measures of singing accuracy, the long note singing accuracy measures, demographic variables, and features of participants' hardware setup. Consequently, we release five R packages which facilitate deploying melodic stimuli online and in laboratory contexts, constructing audio production tests, transcribing audio in the R environment, and deploying the test elements and their supporting models. These are published as open-source, easy to access, and flexible to adapt.","2024-08","2025-04-25 15:31:15","2025-04-25 15:31:15","","4358-4384","","5","56","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A FLOSS project usually has a community around its project, organically producing informative resources to describe how, when, and why a particular change occurred in the source code or the development flow. Therefore, when studying this kind of project, collecting and analyzing texts and artifacts can promote a more comprehensive understanding of the phenomenon and the variety of organizational settings. However, despite the importance of examining Grey Literature (GL), such as technical reports, white papers, magazines, and blog posts for studying FLOSS projects, the GL Review is still an emerging technique in software engineering studies, lacking a well-established investigative methodology. To mitigate this gap, we present and discuss challenges and adaptations for the planning and execution of GL reviews in the FLOSS scenario. We provide a set of guidelines and lessons learned for further research, using, as an example, a review we are conducting on the Linux kernel development model.","2020","2025-04-25 15:31:16","2025-04-25 15:31:16","","89-92","","","","","","","","","","","IEEE; ACM; ACM SIGSOFT; IEEE Comp Soc; IEEE Tech Council Software Engn","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Urban environments must therefore be at the heart of any global energy transition. Furthermore, land availability is a limiting factor for renewable deployment and rooftop PV thus offers a clear advantage. This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 % of the total electricity consumption of the city and where 50 % of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies. Additionally, this article provides valuable information, such as rooftop usability factors, and an overall reduction factor (CT), useful to extend RPVP assessment to larger areas using constant value methods.","2025-03-15","2025-04-25 15:31:16","2025-04-25 15:31:16","","","","","331","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Global action plans to address non-communicable diseases (NCDs) recognise the centrality of community engagement to create an enabling environment within which to address risk factors. Study design: In this article, we describe and critically reflect on a cocreated community engagement approach to address type 2 diabetes in the southern plains of Nepal. We coproduced the engagement approach with 40 artists from the Janakpur Women's Development Centre to create an environment for dialogue about diabetes and NCD risk between artists and the general public. Methods: We used participatory action research to produce contextually relevant interactive methods and materials. Methods included artists' peer research to inform creative workshops, a drama performed in 19 villages and a two-day funfair in a public park. We used qualitative and participatory methods to analyse the effect of this engagement and reflect on lessons learned. Results: Around 2000 people saw the drama, and around 4000 people attended the funfair. Community dialogue about prevention of diabetes was facilitated by drama and through games and songs at the funfair. Artists grew confident to interact with their peers and drama audiences about the causes of diabetes and prevention strategies. Despite crowds at the funfair, it was difficult to reach women because the venue was often used by men and boys, and patriarchal norms prevent women from free movement. Village interactions were able to engage a more mixed audience. Conclusion: Innovative, asset-based community engagement about diabetes and other NCDs at scale is possible through locating, building on and strengthening community resources to address local health issues. Engagement could be enhanced by considering the gendered nature of community engagement spaces and by increasing opportunities for interaction between artists and the general public through more intimate and large-scale events.

The development of multiple chemical derivatization strategies and bioinformatic software is responsible for some of the greatest analytical gains in the field of glycomics. The INLIGHT strategy is a chemical derivatization technique using hydrazide chemistry to derivatize the reducing end of N-linked glycans and incorporates either a natural (NAT, C-12(6)) or a stable-isotope label (SIL, C-13(6)) to carry out relative quantification. Here we present GlycoHunter, a user-friendly software created in MATLAB that enables researchers to accurately and efficiently process MS1 glycomics data where a NAT and SIL pair is generated for relative quantification, including but not limited to, INLIGHT. GlycoHunter accepts the commonly used data file formats imzML and mzXML and effectively identifies all peak pairs associated with NAT- and SIL-labeled N-linked glycans using MS1 data.

Researchers have suggested that the corporatization of FLOSS affords opportunities for creating an inclusive workforce. To understand the potential for firms to increase diversity, we conducted a mixed-methods study of diversity and corporate engagement in FLOSS projects. We integrate the results of a qualitative survey and a big data analysis to understand developer perceptions of corporate engagement and its association with gender and geographic diversity. In the qualitative component, we collected responses from 64 FLOSS contributors to elicit their perspectives on corporate engagement. In the quantitative component, we analyzed GitHub data from 38 projects and 9,990 contributors to investigate differences in participation and diversity based on corporate engagement. We find that contributors vary across dimensions that can inform diversity interventions: stances toward corporations and orientation towards individual/collective benefits. Our results suggest that corporate engagement may limit a project's contributor base and geographic diversity. Yet, organizations subsidizing FLOSS have opportunities to increase access to projects which would benefit diversity. This research serves to identify individual and organizational factors which may harm and help diversity initiatives.","2024-11","2025-04-25 15:31:16","2025-04-25 15:31:16","","","","","217","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the technical skills required to extract tailored information about land cover dynamics from these open-access geospatial data often limit their use by those making landscape management decisions. Using Dartmoor National Park as an example, we demonstrate an open-source toolkit which uses open-source software (QGIS and RStudio) to process freely available Sentinel-2 and public LiDAR data sets to produce fine scale (10 m(2) grain size) land cover maps. The toolbox has been designed for use by staff within the national park, for example, enabling land cover maps to be updated as required in the future. An area of 945 km(2) was mapped using a trained random forest classifier following a classification scheme tailored to the needs of the national park. A 2019 land cover map had an overall user's accuracy of 79%, with 13 out of 17 land cover classes achieving greater than 70% accuracy. Spatially, accuracy was related via logistical regression to blue band surface reflectance in the spring and topographic slope derived from LiDAR (1 m resolution), with greater accuracy in steeper terrain and areas exhibiting higher blue reflectance. Between an earlier (2017-2019) and later (2019-2021) time frame, 8% of pixels changed, most of the change by area occurred in the most common classes. However, the largest proportional increase occurred in Upland Meadows, Lowland Meadows and Blanket Bog, all habitats subject to restoration efforts. Identifying areas of change enables future field work to be better targeted. We discuss the application of this mapping to land management within the Dartmoor national park and of the potential of tailored land cover and land cover change mapping, via this toolbox, to evidence-based environmental decision-making more widely.","2022-06","2025-04-25 15:31:16","2025-04-25 15:31:16","","","","3","3","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In contrast to shotgun proteomics, proteins/peptides can be detected directly from biological tissues and correlated to its morphology leading to a gain of crucial clinical information. However, direct identification of the detected molecules is currently challenging for MALDI-IMS, thereby compelling researchers to use complementary techniques and resource intensive experimental setups. Despite these strategies, sufficient information could not be extracted because of lack of an optimum data combination strategy/software. Here, we introduce a new open-source software ImShot that aims at identifying peptides obtained in MALDI-IMS. This is achieved by combining information from IMS and shotgun proteomics (LC-MS) measurements of serial sections of the same tissue. The software takes advantage of a two group comparison to determine the search space of IMS masses after deisotoping the corresponding spectra. Ambiguity in annotations of IMS peptides is eliminated by introduction of a novel scoring system that identifies the most likely parent protein of a detected peptide in the corresponding IMS dataset. Thanks to its modular structure, the software can also handle LC-MS data separately and display interactive enrichment plots and enriched Gene Ontology terms or cellular pathways. The software has been built as a desktop application with a conveniently designed graphic user interface to provide users with a seamless experience in data analysis. ImShot can run on all the three major desktop operating systems and is freely available under Massachusetts Institute of Technology license.","2022-06","2025-04-25 15:31:16","2025-04-25 15:31:16","","","","6","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Collectively, these data can be analyzed for such purposes as disease diagnosis or phenotype classification. One family of algorithms that has proven useful for disease classification is based on relative expression analysis and includes the Top-Scoring Pair (TSP), k-Top-Scoring Pairs (k-TSP), Top-Scoring Triplet (TST) and Differential Rank Conservation (DIRAC) algorithms. These relative expression analysis algorithms hold significant advantages for identifying interpretable molecular signatures for disease classification, and have been implemented previously on a variety of computational platforms with varying degrees of usability. To increase the user-base and maximize the utility of these methods, we developed the program AUREA (Adaptive Unified Relative Expression Analyzer)-a cross-platform tool that has a consistent application programming interface (API), an easy-to-use graphical user interface (GUI), fast running times and automated parameter discovery. Results: Herein, we describe AUREA, an efficient, cohesive, and user-friendly open-source software system that comprises a suite of methods for relative expression analysis. AUREA incorporates existing methods, while extending their capabilities and bringing uniformity to their interfaces. We demonstrate that combining these algorithms and adaptively tuning parameters on the training sets makes these algorithms more consistent in their performance and demonstrate the effectiveness of our adaptive parameter tuner by comparing accuracy across diverse datasets. Conclusions: We have integrated several relative expression analysis algorithms and provided a unified interface for their implementation while making data acquisition, parameter fixing, data merging, and results analysis `point- and -click' simple.

But is deliberate change also possible without formal structures and hierarchical influence? Design/methodology/approach - This longitudinal, qualitative study investigates an open-source software (OSS) community named TYPO3. This case exhibits no formal hierarchical attributes. The study is based on mailing lists, interviews and observations. Findings - The study reveals that deliberate change is indeed achievable in a non-hierarchical collaborative OSS community context. However, it presupposes the presence and active involvement of informal change agents. The paper identifies and specifies four key drivers for change agents' influence. Originality/value - The findings contribute to organisational analysis by providing a deeper understanding of the importance of leadership in making deliberate change possible in non-hierarchical settings. It points to the importance of “change-by-conviction”, essentially based on voluntary behaviour.

In this era where most of the similar processes are automated, manual application may result in excessive time consumption, unnecessary use of qualified work-force, and is also open to error. A software that automates these processes for neuropsychological tests used for dementia assessment may overcome these issues. Methods: We aimed to develop a free, open source software not requiring specialized training, which would optimise the calculation, preparation of personal reports and archiving processes of neuropsychological tests, hence would easily be incorporated in to the daily work of psychologists. We've used Python 3.6 as the programming language, and JSON was used as the data interchange format to allow for personal alterations in the content. The tests were selected among those which are in common use for neuropsychological evaluation of adults in Turkey, with available norm values. (Funding: TUBITAK 214S048). Results: PsiNorm was developed, comprising widely used standardized tests for cognitive evaluation of adults in Turkey.

Our methods are based on complex network and time-series analysis. We define the notion of a working rhythm as the average time spent on a commit task and we study the correlation between working rhythm and communication frequency. We build communication networks for code developers, and find that the developers with higher social status, represented by the nodes with larger number of outgoing or incoming links, always have faster working rhythms and thus contribute more per unit time to the projects. We also study the dependency between work (committing) and talk (communication) activities, in particular the effect of their interleaving. We introduce multi-activity time-series and quantitative measures based on activity latencies to evaluate this dependency. Comparison of simulated time-series with the real ones suggests that when work and talk activities are in proximity they may accelerate each other in OSS systems. These findings suggest that frequent communication before and after committing activities is essential for effective software development in distributed systems.","2012","2025-04-25 15:31:16","2025-04-25 15:31:16","","78-85","","","","","","","","","","","Acad Sci & Engn; IEEE Comp Soc","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The quantification of tumor heterogeneity with molecular images, by analyzing the local or global variation in the spatial arrangements of pixel intensity with texture analysis, possesses a great clinical potential for treatment planning and prognosis. To address the lack of available software for computing the tumor heterogeneity on the public domain, we develop a software package, namely, Chang-Gung Image Texture Analysis (CGITA) toolbox, and provide it to the research community as a free, open-source project. Methods. With a user-friendly graphical interface, CGITA provides users with an easy way to compute more than seventy heterogeneity indices. To test and demonstrate the usefulness of CGITA, we used a small cohort of eighteen locally advanced oral cavity (ORC) cancer patients treated with definitive radiotherapies. Results. In our case study of ORC data, we found that more than ten of the current implemented heterogeneity indices outperformed SUVmean for outcome prediction in the ROC analysis with a higher area under curve (AUC). Heterogeneity indices provide a better area under the curve up to 0.9 than the SUVmean and TLG (0.6 and 0.52, resp.). Conclusions. CGITA is a free and open-source software package to quantify tumor heterogeneity from molecular images. CGITA is available for free for academic use at http://code.google.com/p/cgita.","2014","2025-04-25 15:31:16","2025-04-25 15:31:16","","","","","2014","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The most popular software for landscape metrics evaluation is FRAGSTATS, which is free to use but does not have free or open source software (FOSS). Therefore, FOSS implementations, such as QGIS's LecoS plugin and GRASS' r.li modules suite, were developed. While metrics are defined in the same way, the “cell neighborhood” parameter, specifying the configuration of the moving window used for the analysis, is managed differently: FRAGSTATS can use values of 4 or 8 (8 is default), LecoS uses 8 and r.li 4. Tests were performed to evaluate the landscape metrics variability depending on the “cell neighborhood” values: some metrics, such as “edge density” and “landscape shape index”, do not change, other, for example “patch number”, “patch density”, and “mean patch area”, vary up to 100% for real maps and 500% for maps built to highlight this variation. A review of the scientific literature was carried out to check how often the value of the “cell neighborhood” parameter is explicitly declared. A method based on the “aggregation index” is proposed to estimate the effect of the uncertainty on the “cell neighborhood” parameter on landscape metrics for different maps.","2019-12","2025-04-25 15:31:16","2025-04-25 15:31:16","","","","12","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

User participation is becoming a relevant topic of research in the OSS development context. Though it has not been examined much to date, the OSS development context has been argued to advocate a particular type of participatory design, which can now be scrutinised in its natural setting as it evolves. Two interpretive case studies on user participation in OSS development are included in this article. The first examines a traditional community OSS development project; the second concentrates on the company OSS development context, the case being a software development unit of a global corporation involved in OSS development. Through analysis of the cases, different forms of participatory design (PD), especially of distributed PD, are identified. Distributed PD is interpreted to include gaining an understanding of users' current practices, redesigning them together with users and gathering feedback from users related to the solutions. Different kinds of roles are available to users, as well as to for intermediaries `representing users'. Especially, the importance of online forum-based and intermediary-driven PD is emphasised in this article.

Constructing simulations to assess the effect of the penetration of distributed generation on electrical distribution networks has become of great importance for Distribution Network Operators (DNOs). This paper proposes a simulation strategy based on open-source platforms and the integration of scripting tools for the rapid modeling of large-scale electrical distribution circuits with distributed renewable generation. The implementation is based on the adaptation of a tool called QGIS2OpenDSS, which creates OpenDSS distribution network models directly from an open-source geographic information system, QGIS. The plugin's capabilities are demonstrated using a real distribution feeder with more than 60% penetration of renewable generation based on photovoltaic systems. These simulations are carried out using real data from a circuit provided by a DNO in the Dominican Republic, which is used to demonstrate how this approach provides a more accessible and flexible way to simulate and assess the effect of Distributed Energy Resources (DERs) in medium voltage (MV) and low voltage (LV) networks, enabling utilities to evaluate system performance and identify potential issues. The integration of this open-source tool within the DNO software stack enables users to apply it according to specific project needs, enhancing their capability to analyze and manage high DER penetration levels, aiding in better planning, operation, and decision-making processes related to renewable energy projects.","2024-06","2025-04-25 15:31:17","2025-04-25 15:31:17","","","","12","17","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Interpreting this data involves inferring the masses and abundances of biomolecules injected into the instrument. Because of the inherent complexity of mass spectral patterns produced by these biomolecules, the analysis is significantly enhanced by using visualization capabilities to inspect and confirm results. In this paper we describe Decon2LS, an open-source software package for automated processing and visualization of high-resolution MS data. Drawing extensively on algorithms developed over the last ten years for ICR2LS, Decon2LS packages the algorithms as a rich set of modular, reusable processing classes for performing diverse functions such as reading raw data, routine peak finding, theoretical isotope distribution modelling, and deisotoping. Because the source code is openly available, these functionalities can now be used to build derivative applications in relatively fast manner. In addition, Decon2LS provides an extensive set of visualization tools, such as high performance chart controls. Results: With a variety of options that include peak processing, deisotoping, isotope composition, etc, Decon2LS supports processing of multiple raw data formats. Deisotoping can be performed on an individual scan, an individual dataset, or on multiple datasets using batch processing. Other processing options include creating a two dimensional view of mass and liquid chromatography (LC) elution time features, generating spectrum files for tandem MS data, creating total intensity chromatograms, and visualizing theoretical peptide profiles. Application of Decon2LS to deisotope different datasets obtained across different instruments yielded a high number of features that can be used to identify and quantify peptides in the biological sample. Conclusion: Decon2LS is an efficient software package for discovering and visualizing features in proteomics studies that require automated interpretation of mass spectra. Besides being easy to use, fast, and reliable, Decon2LS is also open-source, which allows developers in the proteomics and bioinformatics communities to reuse and refine the algorithms to meet individual needs.

Therefore, this research aims to see if open source software has the potential to influence the cybersecurity market that is currently dominated by proprietary software. However, in order to accomplish such a task, certain conditions must be met. Such as understanding of the history behind open source software, the positive and negative influences it carries when dealing with this type of software. As well as compare and contrast current proprietary solutions with open source solutions, in order to grasp the potential economic impact of open source software leading onwards into the future. The ideal findings would be to outline the factors that are holding back open source software, and whether these factors are adjustable or correctable over time. Another aim is to highlight the potential financial benefit that comes from switching to or prioritizing OSS security solutions. As well as come up with any recommendations that would help aid businesses and organizations when it comes to obtaining suitable OSS security solutions.","2019","2025-04-25 15:31:17","2025-04-25 15:31:17","","115-127","","","","","","","Advances in Science Technology & Innovation","","","","Amer Univ","","","","","","","","","ISSN: 2522-8714","","","","","","AlMasri, A; Curran, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key challenge in DFN model parameterization is that parameters measured from cell tear-down experiments cannot be directly used in simulations, and parameter identification is required to accurately reflect real-world battery dynamics However, existing open-source DFN codes lack the capability to perform parameter identification and operate in open-loop mode. COBRAPRO addresses this gap by implementing a systematic parameterization pipeline to accurately determine parameters using battery current and voltage data. Concepts from structural and practical identifiability are utilized to determine parameters that can be fixed to their experimental values and parameters that are suitable for optimization. In the parameter identification process, particle swarm optimization is used to minimize the error between experimental data and simulation results. Additionally, COBRAPRO incorporates a robust method to determine consistent initial conditions and utilizes a fast numerical solver for improved performance. We demonstrate COBRAPRO's parameter identification framework on reference performance test data obtained from LG INR21700-M50T cells. The parameterized model is validated against driving cycle data, showing good agreement between the experimental and simulation results.","2024-09-02","2025-04-25 15:31:17","2025-04-25 15:31:17","","","","9","171","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose a multiplex bipartite network ranking model, M-BiRank, to co-rank developers and projects using multiple developer-project interactions. Firstly, multiple developer-project interactions such as commit, issue, and watch are extracted and a multiplex developer-project bipartite network is constructed. Secondly, a random layer is selected from this multiplex bipartite network and initial ranking scores are calculated for developers and projects using BiRank. Finally, initial ranking scores diffuse to other layers and mutual reinforcement is taken into consideration to iteratively calculate ranking scores of developers and projects in different layers.

In such perspective, it has become common place to refer to FOSS as a manifestation of collective intelligence where deliverables and artefacts emerge by virtue of mere cooperation, with no need for supervising leadership. We show that this assumption is based on limited understanding of the software development process, and may lead to wrong conclusions as to the potential of peer production. The development of a less than trivial piece of software, irrespective of whether it be FOSS or proprietary, is a complex cooperative effort requiring the participation of many (often thousands of) individuals. A subset of the participants always play the role of leading system and subsystem designers, determining architecture and functionality; the rest of the people work “underneath” them in a logical, functional sense. While new and powerful forces, including FOSS, are clearly at work in the post-industrial, networked economy, the currently ingenuous stage of research in the field of collective intelligence and networked cooperation must give way to a deeper level of consciousness, which requires an understanding of the software development process.","2010","2025-04-25 15:31:17","2025-04-25 15:31:17","","285-292","","","","","","","","","","","","","","","","","","","","","","","","","","Tsui, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Key examples of this include identification of ripening stages of fruit such as tomatoes and the determination of chlorophyll content as an indicator of plant health. While methods exist for determining these important phenotypes, they often require proprietary software or require coding knowledge to adapt existing code.ResultsWe provide a set of free and open-source Python scripts that, without any adaptation, are able to perform background correction and colour correction on images using a ColourChecker chart. Further scripts identify objects, use an object of known size to calibrate for size, and extract the average colour of objects in RGB, Lab, and YUV colour spaces. We use two examples to demonstrate the use of these scripts. We show the consistency of these scripts by imaging in four different lighting conditions, and then we use two examples to show how the scripts can be used. In the first example, we estimate the lycopene content in tomatoes (Solanum lycopersicum) var. Tiny Tim using fruit images and an exponential model to predict lycopene content. We demonstrate that three different cameras (a DSLR camera and two separate mobile phones) are all able to model lycopene content. The models that predict lycopene or chlorophyll need to be adjusted depending on the camera used. In the second example, we estimate the chlorophyll content of basil (Ocimum basilicum) using leaf images and an exponential model to predict chlorophyll content.ConclusionA fast, cheap, non-destructive, and inexpensive method is provided for the determination of the size and colour of plant materials using a rig consisting of a lightbox, camera, and colour checker card and using free and open-source scripts that run in Python 3.8.

Our approach utilizes newly derived analytic gradients for maximizing the transition probability (based on a norm-conserving Crank-Nicolson propagation scheme) for driving a system from a known initial quantum state to another desired state. The NIC-CAGE code is written in the MATLAB and Python programming environments to aid in its readability and general accessibility to both users and practitioners.

Therefore, how to choose an appropriate SRGM for software reliability evaluation in the current software development and testing environment is an important practical issue. In this study, we proposed a weighted Grey relational analysis method to select the optimal SRGMs, including closed- and open-source SRGMs, as well as perfect and imperfect debugging SRGMs. To effectively validate the effectiveness of the proposed method, we used 12 SRGMs, 11 model evaluation criteria, and 2 successive versions of open-source software fault datasets. Results of this study indicated that the proposed method can select the optimal SRGM in the current software development and testing environment.

It simulates the macro- and micromixing scales, and the complete energy and population balance equations during crystal nucleation and growth. The model is based on the Reynolds-Averaged-Navier-Stokes equation, coupled with a three-environment presumed probability density function model, and the spatially varying population balance equation semidiscretized using a high resolution finite-volume method. openCrys is implemented in C++ object oriented programming language using the open-source CFD package OpenFOAM. The software is used to compare the performance of dual impinging jet, coaxial, and radial crystallizers. It is shown that improving the micromixing does not necessarily result in a narrower crystal size distribution when temperature effects are taken into account. The complex interplay of crystallizer kinetics and momentum, mass, and heat transfer makes the selection of the best mixer for a particular application to be nonobvious, which motivates the development and application of high-fidelity multiscale simulations for the design of antisolvent crystallizers.","2018-08-29","2025-04-25 15:31:17","2025-04-25 15:31:17","","11702-11711","","34","57","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As there is currently no single diagnostic gold standard test, PCD is diagnosed by a combination of several methods comprising genetic testing and the examination of the ciliary structure and function. Among the approved diagnostic methods, only high-speed video microscopy (HSVM) allows to directly observe the ciliary motion and therefore, to directly assess ciliary function. In the present work, we present our recently developed freely available open-source software - termed “Cilialyzer”, which has been specifically designed to support and facilitate the analysis of the mucociliary activity in respiratory epithelial cells captured by high-speed video microscopy.Methods: In its current state, the Cilialyzer software enables clinical PCD analysts to load, preprocess and replay recorded image sequences as well as videos with a feature-rich replaying module facilitating the commonly performed qualitative visual assessment of ciliary function (including the assessment of the ciliary beat pattern). The image processing methods made accessible through an intuitive user interface allow clinical specialists to comfortably compute the ciliary beating frequency (CBF), the activity map and the “frequency correlation length” - an observable getting newly introduced. Furthermore, the Cilialyzer contains a simple-to-use particle tracking interface to determine the mucociliary transport speed.Results: Cilialyzer is fully written in the Python programming language and freely available under the terms of the MIT license. The proper functioning of the computational analysis methods constituting the Cilialyzer software is demonstrated by using simulated and representative sample data from clinical practice. Additionally, the software was used to analyze high-speed videos showing samples obtained from healthy controls and genetically confirmed PCD cases (DNAI1 and DNAH11 mutations) to show its clinical applicability.Conclusions: Cilialyzer serves as a useful clinical tool for PCD analysts and provides new quantitative information awaiting to be clinically evaluated using cohorts of PCD. As Cilialyzer is freely available under the terms of a permissive open-source license, it serves as a ground frame for further development of computational methods aiming at the quantification and automation of the analysis of mucociliary activity captured by HSVM.","2023-11","2025-04-25 15:31:17","2025-04-25 15:31:17","","","","","241","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Owing to the increase in demand for software products in various fields (big data, artificial intelligence, the Internet of Things, etc.), the software industry has expanded more than ever before. Therefore, software reliability has become very important, and efforts are being made to increase it. One of these efforts is the development of software reliability models (SRMs). SRMs have been studied for a long time as a model that predicts software reliability by using the number of software faults. Software failures can occur for several reasons, including independent software faults such as code errors and software hangs, as well as dependent cases where code errors lead to other software faults. Recently, due to the diversity of software operating environments, software faults are more likely to occur in a dependent manner, and, for this reason, they are likely to increase rapidly from the beginning and progress slowly to the maximum number thereafter. In addition, many large companies have focused on open-source software (OSS) development, and OSS is being developed by many users. In this study, we propose a new SRM that considers the number of finite faults and dependent faults, and examine the goodness-of-fit of a new SRM and other existing non-homogeneous Poisson process models based on the OSS datasets. Through numerical examples, the proposed model demonstrated a significantly better goodness-of-fit when compared to other existing models, and it also exhibited better results on the newly proposed integrated criteria.","2023","2025-04-25 15:31:17","2025-04-25 15:31:17","","11785-11804","","7","20","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Global optimization methods, which provide a robust methodology, and metaheuristics in particular have proven to be the most efficient methods for many applications. Despite their utility, there is a limited availability of metaheuristic tools. Results: We present MEIGO, an R and Matlab optimization toolbox (also available in Python via a wrapper of the R version), that implements metaheuristics capable of solving diverse problems arising in systems biology and bioinformatics. The toolbox includes the enhanced scatter search method (eSS) for continuous nonlinear programming (cNLP) and mixed-integer programming (MINLP) problems, and variable neighborhood search (VNS) for Integer Programming (IP) problems. Additionally, the R version includes BayesFit for parameter estimation by Bayesian inference. The eSS and VNS methods can be run on a single-thread or in parallel using a cooperative strategy.

This paper examines the development of a web GIS application as part of an emission inventory system that produces maps and files with spatial allocated emissions in a grid format. The study is not confined in the maps produced but also presents the features and capabilities of a web application that can be used by every user even without any prior knowledge of the GIS field. The development of the application was based on open source software tools such as MapServer for the GIS functions, PostgreSQL and PostGIS for the data management and HTML, PHP and JavaScript as programming languages. In addition, background processes are used in an innovative manner to handle the time consuming and computational costly procedures of the application. Furthermore, a web map service was created to provide maps to other clients such as the Google Maps API v3 that is used as part of the user interface. The output of the application includes maps in vector and raster format, maps with temporal resolution on daily and hourly basis, grid files that can be used by air quality management systems and grid files consistent with the European Monitoring and Evaluation Programme Grid. Although the system was developed and validated for the Republic of Cyprus covering a remarkable wide range of pollutant and emissions sources, it can be easily customized for use in other countries or smaller areas, as long as geospatial and activity data are available.

A popular example of open innovation has been open source software (OSS). The key issues facing organizational decision makers considering OSS strategies is, how does the firm create value for the customer while simultaneously extracting value for itself? However, the adoption of OSS as part of an open innovation strategy is a recent phenomenon and many unanswered questions remain. Taking the viewpoint of seven IS/IT decision makers in European firms, this paper reveals how decision makers considered aspects of value creation, capture, and networking in making decisions on adopting open source software. The findings reveal that while decision makers look to open innovation for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.","2008","2025-04-25 15:31:18","2025-04-25 15:31:18","","229+","","","287","","","","International Federation for Information Processing","","","","IFIP TC8 WG8 6; Spanish Minist Sci & Innovat; IBM; Ericsson; Madrid City Council; Telefon Invest & Desarrollo; Univ Politen Madrid","","","","","","","","","ISSN: 1571-5736","","","","","","Leon, G; Bernardos, AM; Casar, JR; Kautz, K; DeGross, JI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Method: To reach this aim, we studied the processes and the information considered by the major OSS assessment models. Then we carried out a case study to identify which information can be automatically retrieved from the main OSS platforms, namely GitHub, SonarCloud, and StackExchange. Finally, we characterized the maturity of the projects available on these three platforms. Results: Projects available on the three platforms are commonly old, stable, and mature ones. Moreover, thanks to the API provided, we were able to extract most of the information not commonly accessible from the main website.

On one hand, most FOSS systems are based on very fine-grained units of software deployment - called packages - which promote system evolution; on the other hand, FOSS systems are among the largest software systems known and require sophisticated static and dynamic conditions to be verified, in order to successfully deploy upgrades on users' machines. The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V.

While nowadays new objects are mostly detected in larger sky surveys, several follow-up observations are usually needed for each object to improve the accuracy of orbit determination. In particular objects orbiting close to Earth, so called Near-Earth Objects (NEOs) are of special concern as a small but not negligible fraction of them can have a non-zero impact probability with Earth. Additionally, the observation of manmade space debris and tracking of satellites falls in the same class measurements. Telescopes for these follow-up observations are mainly in a aperture class between 1 m down to approximately 25 cm. These telescopes are often hosted by amateur observatories or dedicated companies like 6ROADS specialized on this type of observation. With upcoming new NEO search campaigns by very wide field of view telescopes, like the Vera C. Rubin Observatory, NASA's NEO surveyor space mission and ESA's Flyeye telescopes, the number of NEO discoveries will increase dramatically. This will require an increasing number of useful telescopes for follow-up observations at different geographical locations. While well-equipped amateur astronomers often host instruments which might be capable of creating useful measurements, both observation planning and scheduling, and also analysis are still a major challenge for many observers. In this work we present a fully robotic planning, scheduling and observation pipeline that extends the widely used open-source cross-platform software KStars/Ekos for Instrument Neutral Distributed Interface (INDI) devices. The method consists of algorithms which automatically select NEO candidates with priority according to ESA's Near-Earth Object Coordination Centre (NEOCC). It then analyses detectable objects (based on limiting magnitudes, geographical position, and time) with preliminary ephemeris from the Minor Planet Center (MPC). Optimal observing slots during the night are calculated and scheduled. Immediately before the measurement the accurate position of the minor body is recalculated and finally the images are taken. Besides the detailed description of all components, we will show a complete robotic hard- and software solution based on our methods.","2022-10-03","2025-04-25 15:31:18","2025-04-25 15:31:18","","","","","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These tests have also proved useful to assess the non-motor symptoms in the animal models of movement disorders such as Parkinson's disease and Huntington's disease. Manual analysis of FST and TST is a time-consuming exercise and has large observer-to-observer variability. Automation of behavioral analysis alleviates these concerns, but there are no easy-to-use open-source tools for such analysis. Here, we describe the development of Depression Behavior Scorer (DBscorer), an open-source program installable on Windows, with an intuitive graphical user interface (GUI), that helps in accurate quantification of immobility behavior in FST and TST from video analysis. Several calibration options allow customization of various parameters to suit the experimental requirements. Apart from the readout of time spent immobile, DBscorer also provides additional data and graphics of immobility/mobility states across time revealing the evolution of behavioral despair over the duration of the test and allows the analysis of additional parameters. Such comprehensive analysis allows a more nuanced understanding of the expression of behavioral despair in FST and TST. We believe that DBscorer would make analysis of behavior in FST and TST unbiased, automated and rapid, and hence prove to be helpful to the wider neuroscience community.","2021-12","2025-04-25 15:31:18","2025-04-25 15:31:18","","","","6","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

The aim of this study was to compare the gliding capacities of different flosses with major differences in structure and experimental behavior in vivo. Methods: In a clinical, single-blind, crossover study of 27 subjects, the forces necessary for passing all 14 proximal contacts between the first premolars were measured using 2 polytetrafluoroethylene (PTFE)-based flosses, 2 nylon-based flosses, and 1 nylon-based tape. The flosses were fixed in a special holder with strain gauges, which allowed registration of the maximum forces at insertion into and removal from the interdental area. Results: In most contacts, the PTFE flosses needed less force compared to the nylon flosses. The range between the flosses was higher in the mandible compared to the maxilla and increased from the mesially located contacts to the more distally located contacts. The nylon tape required higher forces at insertion for all maxillary contacts. All other flosses proved to be equivalent at these contacts. Conclusions: PTFE flosses are superior to nylon flosses in terms of passing stronger proximal contacts in both directions. Due to gliding differences between different types of floss, the selection of a floss has the potential of compensating intra- and interindividual variation in contact strengths.","2001-05","2025-04-25 15:31:19","2025-04-25 15:31:19","","672-678","","5","72","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They are made of thousands of components (software packages) evolving rapidly without centralized coordination. The upgrade of FOSS systems is managed by meta-installers, which solve package dependencies and conflicts and lead the system to a new system configuration by installing or removing packages. Current tools are able to predict a very limited set of upgrade faults before deployment, and this leaves a wide range of faults unpredicted. In this paper, we focus on faults that remain unpredicted, for example, missing packages, packages that are not properly installed, and missing services, with the aim of providing a solution for them. Specifically, in this paper, we propose a model-driven approach and supporting tools to prevent specific classes of system configuration faults before performing the real upgrade. Once the system configuration is represented as a model, the configuration model is evaluated by means of queries, each devoted to discover a specific class of faults. The approach is intrinsically extensible so that user communities can add new queries when new classes of faults are identified. The approach has been validated by executing the fault detector on configuration models in which faults have been intentionally injected and by analyzing produced results.

In this paper, according to the software version sequence, we construct the corresponding developer collaboration network of the Angular OSS community and then analyse this network's structural stability during network evolution. The results show that the network always presents an economical modular small-world structure during its evolution. The maintenance of the structure is related to a cohesive core, which is composed of two types of nodes (i.e., hubs and connectors). The hubs organize noncore nodes to form modules, while connectors facilitate the formation of inter-module connections.

The method EVfold broke new ground using mean-field Direct Coupling Analysis (EVfold-mfDCA); the method PSICOV applied a related concept by estimating a sparse inverse covariance matrix. Both methods (EVfold-mfDCA and PSICOV) are publicly available, but both require too much CPU time for interactive applications. On top, EVfold-mfDCA depends on proprietary software. Results: Here, we present FreeContact, a fast, open source implementation of EVfold-mfDCA and PSICOV. On a test set of 140 proteins, FreeContact was almost eight times faster than PSICOV without decreasing prediction performance. The EVfold-mfDCA implementation of FreeContact was over 220 times faster than PSICOV with negligible performance decrease. EVfold-mfDCA was unavailable for testing due to its dependency on proprietary software.

Existing literature on user innovation and usability is reviewed, after which usability innovation is empirically explored in OSS development. The interpretive ease study shows that usability innovations emerge and evolve in OSS development. They emerge after a user recognizes a need, after which she invents a fix to meet the need, thereafter needing a developer to realize the fix in the OSS. Afterwards, the user experiments with the solution and may provide feedback, which again may lead to the developer adjusting the OSS accordingly.

Some others have investigated knowledge management among open-source-software (OSS) developers and discussed factors influencing knowledge transfer within development teams (e.g. Joshi and Sarker, 2006). In the domain of open source software (OSS) communities, more companies are now attempting to establish relationships to benefit from these potential value-creating communities; and project managers could in fact target different goals within software development teams including knowledge transfer within and between teams. We step forward to distinguish knowledge transfer within groups as opposed to knowledge transfer between groups; where relevant projects are bundled into separate strongly intra-connected groups. In knowledge management literature there is a trade-off between sparse network structures (Burt, 2000, 2002) versus dense network structures (Walker et al., 1997; Coleman, 1988). It is argued that the former facilitates the diffusion and generation of ideas among groups, while the latter affects the implementation of idea within each dense group. To our best knowledge, there has been no study to investigate the relationship between dense and sparse network structures. We propose that knowledge transfer within dense groups has a positive influence on knowledge transfer between sparse groups, in that intragroup density, group size, developers centrality and betweenness could impact intergroup coupling. To prove our hypothesis, we use a complex network of open source software (OSS) as the domain of interest, where developers represent nodes and two developers contributing to a project task represent a network tie. Developers contributing to tasks in groups other than their own can explore novel ideas via sharing knowledge, whereas developers contributing to tasks inside groups exploit ideas to improve those projects. We investigate the idea both analytically and empirically within 4 months, 8 months and 1 year lagged time, and finally show that intragroup density has a positive whereas developers' centrality has a negative influence on intergroup coupling.","2018-02","2025-04-25 15:31:19","2025-04-25 15:31:19","","167-174","","1","38","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our software implements the digital generation of various types of error signals, from an analog input through the application of loop filters of high complexity and real-time gain adjustment for multiple analog output signals, including different algorithms for resonance search, lock acquisition sequences, and in-loop gain optimization. Furthermore, all necessary diagnostic instruments, such as an oscilloscope, a network analyzer, and a spectrum analyzer, are integrated into our software. Apart from providing a quickly scalable, automatic feedback controller, the lock performance that can be achieved by using PyRPL with imperfect equipment, such as piezoelectric transducers and noisy amplifiers, is better than the one achievable with standard analog controllers due to the higher complexity of implementable filters and possibilities of nonlinear operations in the FPGA. This drastically reduces the cost of added complexity when introducing additional feedback loops to an experiment. The open-source character also distinguishes PyRPL from commercial solutions, as it allows users to customize functionalities at various levels, ranging from the easy integration of PyRPL-based feedback controllers into existing setups to the modification of the FPGA functionality.

In this paper, we study the connection between OSS adoption risks and OSS adopter organizations' business goals.

OSS has existed as a model for developing computer applications and software since the 1950s. However, OSS has only found its way into the public arena within the past decade due to some major projects gaining significant market share from commercial developers such as Microsoft. Research in the area of OSS has become more extensive in recent years and has examined areas such as motivation of programmers as well as the benefits of OSS. However, literature focusing on the actual implementation of OSS is more limited with only Fitzgerald and Kenny [(2004). Developing an information infrastructure with Open Source Software. IEEE Software, 50-55] providing any substantial analysis of how it might be achieved. In this paper the focus is on OSS use and implementation within the UK public sector. This sector has a history of resource wastage and underperforming information systems. The underpinning issues of motivation and benefits to organisations will be addressed along with the difficulties that the UK Government faces in adopting an OSS strategy. Section 2 examines the existing literature in the area and explores why OSS should be adopted and implemented by the public sector in the UK. Section 3 considers the research approach taken and the results obtained from considering the implementation of OSS in eight government organisations. Section 4 concludes with a discussion and some implications for those organisations in the public sector who might wish to take this approach.

In most ecological studies, only a single similarity cutoff value is used for sequence identification. This is not sufficient since the most commonly used DNA markers are known to vary widely in terms of inter- and intraspecific variability. We address this problem by presenting a new tool, dnabarcoder, to predict local similarity cutoffs and measure the resolving powers of a biomarker for sequence identification for different clades of fungi. It was shown that the predicted similarity cutoffs varied significantly between the clades of a recently released ITS DNA barcode data set from the CBS culture collection of the Westerdijk Fungal Biodiversity Institute. When classifying a large public fungal ITS data set-the UNITE database-against the barcode data set, the local similarity cutoffs assigned fewer sequences than the traditional cutoffs used in metabarcoding studies. However, the obtained accuracy and precision were significantly improved. Our study showed that it might be better to extract the ITS region from the ITS barcodes to optimize taxonomic assignment accuracy. Furthermore, 15.3, 25.6, and 26.3% of the fungal species of the barcode data set were indistinguishable by full-length ITS, ITS1, and ITS2, respectively. Except for these indistinguishable species, the resolving powers of full-length ITS, ITS1, and ITS2 sequences were similar at the species level. Nevertheless, the complete ITS region had a better resolving power at higher taxonomic levels.","2022-10","2025-04-25 15:31:19","2025-04-25 15:31:19","","2793-2809","","7","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It was first published in 2009 and since then several related projects are on-going. Its objective is the investigation of strategies for enhancing the accuracy of low-cost single-frequency GPS receivers, mainly by relative positioning with respect to a base station and by a tailored extended Kalman filter working directly on code and phase observations. In this paper, the positioning algorithms implemented in goGPS are presented, emphasizing the modularity of the software design; two specific strategies to support the navigation with low-cost receivers are also proposed and discussed, namely an empirical observation weighting function calibrated on the receiver signal-to-noise ratio and the inclusion of height information from a digital terrain model as an additional observation in the Kalman filter. The former is crucial when working with high-sensitivity receivers, while the latter can significantly improve the positioning in the vertical direction. The overall goGPS positioning accuracy is assessed by comparison with a dual-frequency receiver and with the positioning computed by a standard low-cost receiver. The benefits of the calibrated weighting function and the digital terrain model are investigated by an experiment in a dense urban environment. It comes out that the use of goGPS and low-cost receivers leads to results comparable with those obtained by higher level receivers; goGPS has good performances also in a dense urban environment, where its additional features play an important role.","2013-11","2025-04-25 15:31:19","2025-04-25 15:31:19","","","","11","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

NP3 MS Workflow adds improved computing of the MS2 spectra in an LC-MS/MS data set and provides tools for automatic [M + H](+) ion deconvolution using fragmentation rules; chemical structural annotation against MS2 databases; and relative quantification of the precursor ions for bioactivity correlation scoring. The software will be presented with case studies and comparisons with equivalent tools currently available.

The productivity of such development teams, i.e., how their size is related to the produced output, is an important consideration for project and schedule management as well as for cost estimation. The majority of studies in empirical software engineering suggest that - due to coordination overhead - teams of collaborating developers become less productive as they grow in size. This phenomenon is commonly paraphrased as Brooks' law of software project management, which states that “adding manpower to a software project makes it later”. Outside software engineering, the non-additive scaling of productivity in teams is often referred to as the Ringelmann effect, which is studied extensively in social psychology and organizational theory. Conversely, a recent study suggested that in Open Source Software (OSS) projects, the productivity of developers increases as the team grows in size. Attributing it to collective synergetic effects, this surprising finding was linked to the Aristotelian quote that “the whole is more than the sum of its parts”. Using a data set of 58 OSS projects with more than 580,000 commits contributed by more than 30,000 developers, in this article we provide a large-scale analysis of the relation between size and productivity of software development teams. Our findings confirm the negative relation between team size and productivity previously suggested by empirical software engineering research, thus providing quantitative evidence for the presence of a strong Ringelmann effect. Using fine-grained data on the association between developers and source code files, we investigate possible explanations for the observed relations between team size and productivity. In particular, we take a network perspective on developer-code associations in software development teams and show that the magnitude of the decrease in productivity is likely to be related to the growth dynamics of co-editing networks which can be interpreted as a first-order approximation of coordination requirements.","2016-04","2025-04-25 15:31:20","2025-04-25 15:31:20","","642-683","","2","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere. I argue that these competing views are consequential, for they link technical artifacts and political agents in practice, by way of aspirations, obligations, and forms of authority. Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.","2007-05","2025-04-25 15:31:20","2025-04-25 15:31:20","","211-235","","2","93","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, I will demonstrate how open source software may be used for achieving similar purposes. However, the interplay between local copyright law, public procurement law and open source community norms creates many issues relating to the legal status and ownership in modified software, based on open source. This is especially so in the case of so-called copyleft open source licenses, where a collision occurs between copyright, as an absolute right enforceable against the world, and the copyleft provisions of license agreements, which may be treated as “rights in personam” enforceable only against the licensee. The exclusive right to derivative software as an independent object of copyright, may come into conflict with restrictions inherited from incoming copyleft licenses. This paper provides an overview and analysis of such problems faced by Russian software developers, attempting to comply with Russian import substitution provisions, by using open source components. Although it is based on Russian law, it may be applicable to other jurisdictions, since general aspects of copyright law and its interaction with private international law and contract law drive it. The paper concludes that the developer of software, containing code licensed under GEL or other copyleft provisions, receives full exclusive right to the derivative software and can commercialize it as he sees appropriate, subject only to possible claims of breach of contract rather than copyright infringement. This opens wide perspectives for using open source components regardless of the type of license used as bricks for building a de-globalized economy and society based on principles of information sovereignty.

VO(2)FITTING was developed in Shiny, a web application framework for R language. Validation VO2 datasets with both noisy and non-noisy data were developed and applied to widely-used models (n = 7) for describing different intensity transitions to verify concurrent validity. Subsequently, we then conducted an experiment with age-group swimmers as an example, illustrating how VO(2)FITTING can be used to model VO2 kinetics. Perfect fits were observed, and parameter estimates perfectly matched the known inputted values for all available models (standard error = 0; p < 0.001).

For example, the size and shape of activated sludge flocs can indicate the conditions at the microscale, and also directly affect how well the sludge settles in a clarifier. Particle size and shape are both misleadingly `simple' measurements. Many subtle issues, often unaddressed in informal protocols, can arise when sampling, imaging, and analyzing particles. Sampling methods may be biased or not provide enough statistical power. The samples themselves may be poorly preserved or undergo alteration during immobilization. Images may not be of sufficient quality; overlapping particles, depth of field, magnification level, and various noise can all produce poor results. Poorly specified analysis can introduce bias, such as that produced by manual image thresholding and segmentation. Affordability and throughput are desirable alongside reproducibility. An affordable, high throughput method can enable more frequent particle measurement, producing many images containing thousands of particles. A method that uses inexpensive reagents, a common dissecting microscope, and freely-available open source analysis software allows repeatable, accessible, reproducible, and partially-automated experimental results. Further, the product of such a method can be well-formatted, well-defined, and easily understood by data analysis software, easing both within-lab analyses and data sharing between labs. We present a protocol that details the steps needed to produce such a product, including: sampling, sample preparation and immobilization in agar, digital image acquisition, digital image analysis, and examples of experiment-specific figure generation from the analysis results. We have also included an open-source data analysis pipeline to support this protocol.","2019-01","2025-04-25 15:31:20","2025-04-25 15:31:20","","","","143","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the geomorphologic survey, different landforms have been identified in the area, including structural, anthropogenic, fluvial, karst, and slope forms. In particular, the majority of the slope forms are complex (from topple to rotational slides and falls), but there are also minor forms like debris flows and mudslides. To manage geomorphological data, an Open Source GIS was used, which contained the following components: QuantumGIS, System for Automated Geoscientific Analyses (SAGA), GIS and Geographic Resources Analysis Support System (GRASS), GIS for Digital Elevation Model (DEM) generation. A key aim was to make the project-derived data available over the Web. This was achieved using MapServer which allows for the representation of the derived geospatial data with pMapper providing the graphical Web interface. Our study highlights the process dynamics of run-off erosion in Olvera derived through the use of advanced computer-based mapping tools.

This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

The advantages of crowdsourcing include a higher volume of requirements reflecting a more comprehensive array of use cases and a more engaged and committed user base. Researchers cite the inability of project teams to effectively manage an increasing volume of system requirements as a possible drawback. This paper analyzes a data set consisting of project management artifacts from 562 open-source software (OSS) projects to determine how OSS project performance varies as the share of crowdsourced requirements increases using six measures of effectiveness: requirement close-out time, requirement response time, average comment activity, the average number of requirements per crowd member, the average retention time for crowd members, and the total volume of requirements. Additionally, the models measure how the impact of increasing the share of crowdsourced requirements changes with stakeholder network structure. The analysis shows that stakeholder network structure impacts OSS performance outcomes and that the effect changes with the share of crowdsourced requirements. OSS projects with more concentrated stakeholder networks perform the best. The results indicate that requirements crowdsourcing faces diminishing marginal returns. OSS projects that crowdsource more than 70% of their requirements benefit more from implementing processes to organize and prioritize existing requirements than from incentivizing the crowd to generate additional requirements. Analysis in the paper also suggests that OSS projects could benefit from employing CrowdRE techniques and assigning dedicated community managers to more effectively channel input from the crowd.","2021-12","2025-04-25 15:31:20","2025-04-25 15:31:20","","509-534","","4","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Model predictive control (MPC) has been shown to be a successful control strategy generally and as well as for managing urban drainage specifically. This research describes and demonstrates the implementation of MPC for urban drainage systems using open source software (Python and The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM5). The system was demonstrated using a simplified use case in which an actively-controlled outlet of a detention pond is simulated. The control of the pond's outlet influences the flood risk of a downstream node. For each step in the SWMM5 model, a series of policies for controlling the outlet are evaluated. The best policy is then selected using an evolutionary algorithm. The policies are evaluated against an objective function that penalizes primarily flooding and secondarily deviation of the detention pond level from a target level. Freely available Python libraries provide the key functionality for the MPC workflow: step-by-step running of the SWMM5 simulation, evolutionary algorithm implementation, and leveraging parallel computing. For perspective, the MPC results were compared to results from a rule-based approach and a scenario with no active control. The MPC approach produced a control policy that largely eliminated flooding (unlike the scenario with no active control) and maintained the detention pond's water level closer to a target level (unlike the rule-based approach).","2019","2025-04-25 15:31:21","2025-04-25 15:31:21","","988-992","","","","","","","Green Energy and Technology","","","","","","","","","","","","","ISSN: 1865-3529","","","","","","Mannina, G","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This combination of organizational needs and freeware trends led a group of professors from the Faculty of Library and Information Science (UB) and members of the Work Group on Free Software for Information Professionals (Cobdc) to create a virtual laboratory for the use of free software for library applications, as a contribution to the professional community.","2008-02","2025-04-25 15:31:21","2025-04-25 15:31:21","","71-77","","1","17","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Small opaque chambers can be used to measure leaf, stem and soil respiration. Larger transparent chambers can be used to measure net ecosystem exchange of CO2, and small jars often serve this purpose for laboratory incubations of soil and plant material. We developed an Android application (app), called Flux Puppy, to facilitate chamber-based flux measurements in the field and laboratory. The app is designed to run on an inexpensive handheld Android device, such as a tablet or phone, and it has a graphical user interface that communicates with a LI-COR LI-820 and LI-830 (CO2) or LI-840 and LI-850 (CO2/H2O) infrared gas analyzer. The app logs concentrations of CO2 and H2O, cell temperature and pressure at 1 Hz, displays the output graphically, and calculates the linear regression slope, R-squared, and standard error of the CO2 time series. A metadata screen allows users to enter operator, site, and plot information, as well as take a photograph using the Android device's built-in camera, and log measurement location using the device GPS. Additionally, there is a notes field, which can be revised after the measurements are taken. Data files (the 1 s raw data, photograph, and metadata including statistics calculated from the raw data) are then transmitted off the device through file sharing options (Gmail, Outlook, Google Drive, Dropbox etc.). Because Flux Puppy code is open-source (available on GitHub) and the flux measurement system we describe is relatively inexpensive and straightforward to assemble, it should be of broad interest to the carbon cycling community.","2019-08-15","2025-04-25 15:31:21","2025-04-25 15:31:21","","1-6","","","274","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We cast the subspace segmentation problem as that of choosing the best subset of linear subspaces from a set of candidate subspaces constructed from the data. Under this formulation, subspace segmentation corresponds to facility location, a well studied operational research problem. Approximate solutions to this NP-hard optimization problem can be found by performing maximum-a-posteriori (MAP) inference in a probabilistic graphical model.

These formal standards are needed in the telecommunications market to achieve functional interoperability. The standardization process takes years, and then a vendor still needs to implement the resulting standard in a product. This prevents service providers (SPs) who are willing to venture into new domains from doing so at a fast pace. With the development of software-defined networking (SDN) and network function virtualization (NFV), opensource technology is emerging as a new option in the telecommunications market. In contrast to SDOs, open-source software (OSS) communities create a product that may implicitly define a de-facto standard based on market consensus. Therefore, SPs are drawn to OSS, but they face technical, procedural, legal, and cultural challenges due to their lack of experience with open software development. The question therefore arises, how the interaction between OSS communities, SDOs, and industry fora (IF) can be organized to tackle these challenges. This article examines the evolving roles of OSS communities, IF, and SDOs, and places them in an NFV/SDN context. It sketches the differences between these roles and provides guidelines on how the interaction between them can turn into a mutually beneficial relationship that balances the conflicting goals of timely development on the one hand and technical excellence, openness, and fairness on the other, to reach their common goal of creating flexible and efficient telecommunications networks.","2016-03","2025-04-25 15:31:21","2025-04-25 15:31:21","","46-53","","S","54","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The workflow runs on the open-source image analysis software and efficiently separates desired features from low-contrast scanned images. The new workflow is a two-step technique using contrast enhancement and automated feature segmentation to generate noise-free binary images. The results of binary images using the proposed workflow and using a conventional thresholding technique are analyzed to show the quality of the proposed method. The paper also presents a workflow of estimating the structural geometries of features in two and three dimensions. The results of the structural feature analyses and computational time were compared between the open-source (ImageJ) and commercial image analysis software (Bruker Computed Tomography Analyzer). The commercial software was more computationally efficient, but the task-specific macros in open-source software enabled the user-desired automation in image processing and data extraction of desired structural features of comparable quality.","2022-10","2025-04-25 15:31:21","2025-04-25 15:31:21","","2011-2024","","5, SI","39","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To understand how these firms try to harness the work of these communities, I use the empirical data to derive a 22 matrix of different approaches. The X axis reflects whether or not the firms initiated a new community or relied on communities founded by peers, whereas the Y axis represents the degree of participation of the firm in the community. This taxonomy illustrates how de novo entrant are initiating new forms of communities or joining communities established by peers.

Various thematic maps such as lithology/hydrogeology, soil, land-cover/use, slope, lineament density, drainage density and rainfall distribution were integrated in QGIS software. Vector input layers were rasterized and resampled using QGIS wrap projection function to make sure that the grid cells are of the same size. Reclassification using SAGA and GRASS reclass algorithms in QGIS was carried out to realign the factor classes in a consistent scale, and reclassification to a scale of 1 to 5 was carried out to harmonize the results. The study identified a number of potential areas for groundwater recharge, groundwater exploration, groundwater development and potential areas for artificial groundwater recharge. Potential groundwater recharge zones for the Singida semi-arid fractured aquifer are restricted to areas with high lineament density, cultivated areas, grassland and flat to gentle slopes. The potential of groundwater recharge is also observed in areas with low drainage density. The delineated zones provide a good understanding of the potential recharge zones, which are a starting point for recharge zone protection. This blended approach can be utilized for carrying out suitability analysis using the weighted overlay analysis approach. Areas designated good and very good are recommended for artificial recharging structures as an alternative technique for enhancing groundwater recharge through rainwater harvesting. This will help to augment groundwater storage in this semi-arid environment.","2020-06","2025-04-25 15:31:21","2025-04-25 15:31:21","","","","2","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We model the individual's chances to become a valuable contributor through her capacity, willingness, and the opportunity to contribute at the time of joining. Using issue tracking data of Mozilla and Gnome, we find that the probability for a new joiner to become a Long Term Contributor (LTC) is associated with her willingness and environment. Specifically, during their first month, future LTCs tend to be more active and show more community-oriented attitude than other joiners. Joiners who start by commenting on instead of reporting an issue or ones who succeed to get at least one reported issue to be fixed, more than double their odds of becoming an LTC. The micro-climate with a productive and clustered peer group increases the odds. On the contrary, the macro-climate with high project popularity and the micro-climate with low attention from peers reduce the odds. This implies that the interaction between individual's attitude and project's climate are associated with the odds that an individual would become a valuable contributor or disengage from the project.

Modeling Participant's Initial Behavior","IEEE TRANSACTIONS ON SOFTWARE ENGINEERING","","0098-5589","10.1109/TSE.2014.2349496","","Motivation: To survive and succeed, FLOSS projects need contributors able to accomplish critical project tasks. However, such tasks require extensive project experience of long term contributors (LTCs). Aim: We measure, understand, and predict how the newcomers' involvement and environment in the issue tracking system (ITS) affect their odds of becoming an LTC. Method: ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. We also reproduced the results on new data provided by Mozilla. Results: We constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants. Newcomers who are able to get at least one issue reported in the first month to be fixed, doubled their odds of becoming an LTC. The macro-climate with high project popularity and the micro-climate with low attention from peers reduced the odds. The precision of LTC prediction was 38 times higher than for a random predictor. We were able to reproduce the results with new Mozilla data without losing the significance or predictive power of the previously published model. We encountered unexpected changes in some attributes and suggest ways to make analysis of ITS data more reproducible. Conclusions: The findings suggest the importance of initial behaviors and experiences of new participants and outline empirically-based approaches to help the communities with the recruitment of contributors for long-term participation and to help the participants contribute more effectively.

We notably show that such distributions have the characteristics of a small world network: there are only a few important packages, and many less important packages. Identifying the important packages can help editors focus their efforts on parts of the distribution where errors will have important consequences.","2014","2025-04-25 15:31:22","2025-04-25 15:31:22","","417-429","","","8368","","","","Lecture Notes in Computer Science","","","","","","","","","","","","","ISSN: 0302-9743","","","","","","Counsell, S; Nunez, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Among the various techniques available, photoplethysmography stands out as particularly promising for assessing vital signs such as heart rate, respiratory rate, oxygen saturation, and blood pressure. Despite the efficacy of this method, many commercially available wearables, bearing Conformit & eacute; Europ & eacute;enne marks and the approval of the Food and Drug Administration, are often integrated within proprietary, closed data ecosystems and are very expensive. In an effort to democratize access to affordable wearable devices, our research endeavored to develop an open-source photoplethysmographic sensor utilizing off-the-shelf hardware and open-source software components. The primary aim of this investigation was to ascertain whether the combination of off-the-shelf hardware components and open-source software yielded vital-sign measurements (specifically heart rate and respiratory rate) comparable to those obtained from more expensive, commercially endorsed medical devices. Conducted as a prospective, single-center study, the research involved the assessment of fifteen participants for three minutes in four distinct positions, supine, seated, standing, and walking in place. The sensor consisted of four PulseSensors measuring photoplethysmographic signals with green light in reflection mode. Subsequent signal processing utilized various open-source Python packages. The heart rate assessment involved the comparison of three distinct methodologies, while the respiratory rate analysis entailed the evaluation of fifteen different algorithmic combinations. For one-minute average heart rates' determination, the Neurokit process pipeline achieved the best results in a seated position with a Spearman's coefficient of 0.9 and a mean difference of 0.59 BPM. For the respiratory rate, the combined utilization of Neurokit and Charlton algorithms yielded the most favorable outcomes with a Spearman's coefficient of 0.82 and a mean difference of 1.90 BrPM. This research found that off-the-shelf components are able to produce comparable results for heart and respiratory rates to those of commercial and approved medical wearables.","2024-06","2025-04-25 15:31:22","2025-04-25 15:31:22","","","","12","24","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using a large sample of open source software projects, the empirical findings suggest project performance should be distinguished as internal (technical performance) and external (market performance) to understand the effects of open innovation strategy. Technical performance is enhanced with a coupled open innovation strategy that leverages both high outbound open innovation and high inbound open innovation, in conjunction with low team role diversity. However, an inbound open innovation strategy is optimal for market performance, particularly when team role diversity is high.

Most large and complex software packages partitioned across multiple portals and involve many users - each with their role in the software package; those users have different perspectives on the software package, defined by their knowledge, responsibilities, and commitments. Thus, a multi-perspective approach has been used in usability evaluation to overcome the challenge of inconsistency between users' perspectives; the inconsistency challenge would lead to an ill-advised decision on the selection of a suitable OSS. This study aimed to assist the public and private organizations in evaluating and selecting the most suitable OSS. The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.","2023-01","2025-04-25 15:31:22","2025-04-25 15:31:22","","187-277","","01","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As one important module in the GREAT software, GREAT-UPD was developed for multi-GNSS and multi-frequency uncalibrated phase delay (UPD) estimation. It can provide extra-wide-lane (EWL), wide-lane (WL), and narrow-lane (NL) UPDs for GPS, GLONASS, Galileo and BDS (GREC) satellites for precise point positioning (PPP) ambiguity resolution (AR) in a multi-GNSS and multi-frequency environment. The open-source GREAT-UPD software is written in C + + 11 language following object-oriented principles and can be compiled and run on several popular operating systems, such as Windows, Linux, and Macintosh. Observations from 222 stations spanning days from DOY 091 to 120 were used to conduct multi-GNSS and multi-frequency UPD estimation and PPP AR. Results indicate that GREAT-UPD can generate stable and reliable UPD products with multi-GNSS and multi-frequency observations. After applying the UPD corrections, the multi-frequency GREC PPP AR was achieved with the averaged time to first fix of 9.0 min.

We develop a formal model where both volunteers (agents setting their agendas freely) and firm's employees (agents whose agenda is mostly set by their employer) participate in the creation of a common artifact. In this framework, we discuss how firms can influence the architecture of the emerging product to assure fast and performant development and a desirable distribution of innovative labor within the project team. We find that closing the project only to employees implies high speed and performance if employees are given autonomy in certain dimensions and are directed in others. In this case, however, we observe a trade-off in terms of ideal core-periphery division of labor on one side and development speed and performance on the other side. At the opposite extreme, creating a volunteer-only project can ease the trade-off but assures positive results only if the firm is able to set up an entry mechanism that “surgically” selects volunteers with specific preferences. A mixture of both employees and volunteers can strike a good balance, relaxing the two constraints.","2022-11-19","2025-04-25 15:31:23","2025-04-25 15:31:23","","1358-1386","","6","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, there has been a surge in deep learning and computer vision techniques to analyse digital images. Common practice in this area is to use image pre-processing and augmentation to prevent bias and overfitting, creating a more robust deep learning model. This generally requires consultation of documentation for multiple coding libraries, as well as trial and error to ensure that the techniques used on the images are appropriate. Herein we introduce HistoClean; a user-friendly, graphical user interface that brings together multiple image processing modules into one easy to use toolkit. HistoClean is an application that aims to help bridge the knowledge gap between pathologists, biomedical scientists and computer scientists by providing transparent image augmentation and pre-processing techniques which can be applied without prior coding knowledge. In this study, we utilise HistoClean to pre-process images for a simple convolutional neural network used to detect stromal maturity, improving the accuracy of the model at a tile, region of interest, and patient level. This study demonstrates how HistoClean can be used to improve a standard deep learning workflow via classical image augmentation and pre-processing techniques, even with a relatively simple convolutional neural network architecture.

The approach offers a way to capture motion adapted from the film industry in which markers placed on the skin of the face can be tracked with a pattern-matching algorithm. The method records and postprocesses raw facial movement data (coordinates per frame) of distinctly placed markers and is intended for use in facial expression research (e.g., microexpressions) in laboratory settings. Due to the explicit use of specifically placed, artificial markers, the procedure offers the simultaneous measurement of several emotionally relevant markers in a (psychometrically) objective and artifact-free way, even for facial regions without natural landmarks (e.g., the cheeks). In addition, the proposed procedure is fully based on open-source software and is transparent at every step of data processing. Two worked examples demonstrate the practicability of the proposed procedure: In Study 1(N=39), the participants were instructed to show the emotions happiness, sadness, disgust, and anger, and in Study 2 (N=113), they were asked to present both a neutral face and the emotions happiness, disgust, and fear. Study 2 involved the simultaneous tracking of 14 markers for approximately 12 min per participant with a time resolution of 33 ms. The measured facial movements corresponded closely to the assumptions of established measurement instruments (EMFACS, FACSAID, Friesen & Ekman, 1983; Ekman & Hager, 2002). In addition, the measurement was found to be very precise with sub-second, sub-pixel, and sub-millimeter accuracy.","2019-04","2025-04-25 15:31:23","2025-04-25 15:31:23","","747-768","","2","51","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Methods which deliver composite data reflecting the mean values of biomarkers from cell populations risk losing subpopulation dynamics that reflect the heterogeneity of the studied biological system. In keeping with this, traditional approaches are being replaced by, or supported with, more sophisticated forms of cellular assay developed to allow assessment by high-content microscopy. These assays potentially generate large numbers of images of fluorescent biomarkers, which enabled by accompanying proprietary software packages, allows for multi-parametric measurements per cell. However, the relatively high capital costs and overspecialization of many of these devices have prevented their accessibility to many investigators. Described here is a universally applicable workflow for the quantification of multiple fluorescent marker intensities from specific subcellular regions of individual cells suitable for use with images from most fluorescent microscopes. Key to this workflow is the implementation of the freely available Cell Profiler software(1) to distinguish individual cells in these images, segment them into defined subcellular regions and deliver fluorescence marker intensity values specific to these regions.

However, the workflow presented here can be applied to analysis of data from other means of cell perturbation (e.g., compound screens) and other forms of fluorescence based cellular markers and thus should be useful for a wide range of laboratories.","2014-12","2025-04-25 15:31:23","2025-04-25 15:31:23","","","","94","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The software implements a model to explain the allelic peak height on a continuous scale in order to carry out weight-of-evidence calculations for profiles which could be from a mixture of contributors. Through a properly parameterized model we are able to do inference on mixture proportions, the peak height properties, stutter proportion and degradation. In addition, EuroForMix includes models for allele drop-out, allele drop-in and sub-population structure. EuroForMix supports two inference approaches for likelihood ratio calculations. The first approach uses maximum likelihood estimation of the unknown parameters. The second approach is Bayesian based which requires prior distributions to be specified for the parameters involved. The user may specify any number of known and unknown contributors in the model, however we find that there is a practical computing time limit which restricts the model to a maximum of four unknown contributors. EuroForMix is the first freely open source, continuous model (accommodating peak height, stutter, drop-in, drop-out, population substructure and degradation), to be reported in the literature. It therefore serves an important purpose to act as an unrestricted platform to compare different solutions that are available. The implementation of the continuous model used in the software showed close to identical results to the R-package DNAmixtures, which requires a HUGIN Expert license to be used. An additional feature in EuroForMix is the ability for the user to adapt the Bayesian inference framework by incorporating their own prior information. (C) 2015 Elsevier Ireland Ltd.

Education studies have also analysed the importance of these communities in spreading and sharing knowledge and educational culture has looked to these organizational forms for inspiration. At the same time, the link between these experiences and the development of pedagogical models emerging from cognitive sciences, systemic theory and the new forms of constructivism, which have generated a fruitful theory/practice circle, has been reinforced. The aim of this paper is to analyse the particular type of organizational, communicative and productive context of Open Communities: Free Software Communities, to understand how they work, their efficacy and to show their close link with dynamics and relations of an educational, formative and didactic type. Learning communities can still learn strategies of communication, organization and socialization from these communities, as well as the value of motivation and the importance of freedom and circulation of knowledge in order to build up efficient communities. We can also gain the understanding that the success of these communities depends on the fact that they are educational communities, therefore education studies can convey values, models and a culture of sharing to other sectors as well, such as the one taken into consideration: Free Software Communities. The study has been conducted with a research methodology of the phenomenological type thanks to a theoretical study and observation of different free software communities, visiting websites, chats, wiki pages, forums and other channels of discussion and collaboration.","2017","2025-04-25 15:31:23","2025-04-25 15:31:23","","8395-8401","","","","","","","EDULEARN Proceedings","","","","","","","","","","","","","ISSN: 2340-1117","","","","","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Code clones are introduced in the software system by the adoption of common code reuse practices by FOSS developers. This has led the clone research community to observe the effects of code clones on the code quality of FOSS projects. Although code clones are not always harmful but they might become critical to large scale and evolving software systems such as FOSS projects. Research in this paper reveals the importance and need for improving code quality of FOSS projects by implementing an effective clone management system integrated in the FOSS development environment. This paper proposes a clone management framework that ensures effective clone evolution tracking and visualization in FOSS projects. This framework will appear as a baseline to initiate the efforts towards improving code quality by the implementation of a versatile clone management system for FOSS development.","2017","2025-04-25 15:31:23","2025-04-25 15:31:23","","253-258","","","","","","","","","","","Higher Educ Commiss; IEEE; Pakistan Software Export Board; UBL; Bank Alfalah Islam; NAFA; Optcl; EES INT; ERN; ABN; British Canadian Int Educ Ltd; Univ York","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

What is the nature of these novel arrangements? Does volunteers' participation remain critical for these ecosystems? Despite extensive research on commercial participation in OSS, the exact nature and extent of company contributions to OSS development, and the impact of this engagement may have on the volunteer community have not been clarified. To bridge the gap, we perform an exploratory study of OpenStack: a large OSS ecosystem with intense commercial participation. We quantify companies' contributions via the developers that they provide and the commits made by those developers. We find that companies made far more contributions than volunteers and the distribution of the contributions made by different companies is also highly unbalanced. We observe eight unique contribution models based on companies' commercial objectives and characterize each model according to three dimensions: contribution intensity, extent, and focus. Companies providing full cloud solutions tend to make both intensive (more than other companies) and extensive (involving a wider variety of projects) contributions. Usage-oriented companies make extensive but less intense contributions. Companies driven by particular business needs focus their contributions on the specific projects addressing these needs. Minor contributors include community players (e.g., the Linux Foundation) and research groups. A model relating the number of volunteers to the diversity of contribution shows a strong positive association between them.","2021-10-01","2025-04-25 15:31:24","2025-04-25 15:31:24","","2242-2259","","10","47","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These projects often provide onboarding guidelines in their `CONTRIBUTING' files (e.g., CONTRIBUTING.md on GitHub). These files explain, for example, how to find open tasks, implement solutions, and submit code for review. However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions' adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file. Our approach may help community builders identify missing information in the project ecosystem they maintain and newcomers can understand what to expect in CONTRIBUTING files.","2023","2025-04-25 15:31:24","2025-04-25 15:31:24","","16-28","","","","","","","","","","","Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei","","","","","","","","","","","","","","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Architectural decay is, potentially, a major issue in Free/Libre/Open Source Software (FLOSS) projects, since developers sporadically joining FLOSS projects do not always have a clear understanding of the underlying architecture, and may break the overall conceptual structure by several small changes to the code base. This paper investigates whether the structure of a FLOSS system and its decay can also be influenced by the repository in which it is retained: specifically, two FLOSS repositories are studied to understand whether the complexity of the software structure in the sampled projects is comparable, or one repository hosts more complex systems than the other It is also studied whether the effort to counteract this complexity is dependent on the repository, and the governance it gives to the hosted projects. The results of the paper are two-fold: on one side, it is shown that the repository hosting larger and more active projects presents more complex structures. On the other side, these larger and more complex systems benefit from more anti-regressive work to reduce this complexity.","2009","2025-04-25 15:31:24","2025-04-25 15:31:24","","169-178","","","","","","","European Conference on Software Maintenance and Reengineering","","","","IEEE Comp Soc","","","","","","","","","ISSN: 1944-2793","","","","","","Winter, A; Knodel, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose to embed all the knowledge about each OSS adoption strategy into an i* model that can be used in the intentional modeling of the organization. These models describe the consequences of adopting one such strategy or another: which are the business goals that are supported, which are the resources that emerge, etc. To this aim, we first enumerate the main existing OSS adoption strategies, next we formulate an ontology that comprises the activities and resources that characterise these strategies, then based on the experience of 5 industrial partners of the RISCOSS EU-funded project, we explore how these elements are managed in each strategy and formulate the corresponding model using the i* framework.","2014","2025-04-25 15:31:24","2025-04-25 15:31:24","","349-362","","","8824","","","","Lecture Notes in Computer Science","","","","Penn State Univ; Singapore Management Univ TCS, iCity Lab; BYU, Marriott Sch Management; Aalto Univ; QUT","","","","","","","","","ISSN: 0302-9743","","","","","","Yu, E; Dobbie, G; Jarke, M; Purao, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. “simple”, intermediate” or “complex”, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.","2020-07-15","2025-04-25 15:31:24","2025-04-25 15:31:24","","","","","266","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Field defect predictions for open source soft-ware systems may allow organizations to make informed decisions regarding open source software components. In this paper, we remotely measure and analyze predictors (metrics available before release) mined from established data sources (the code repository and the request tracking system) as well as a novel source of data (mailing list archives) for nine releases of OpenBSD. First, we attempt to predict field defects by extending a software reliability model fitted to development defects. We find this approach to be infeasible, which motivates examining metrics-based field defect prediction. Then, we evaluate 139 predictors using established statistical methods: Kendall's rank correlation, Pearson's rank correlation, and forward AIC model selection. The metrics we collect include product metrics, development metrics, deployment and usage metrics, and software and hardware configurations metrics. We find the number of messages to the technical discussion mailing list during the development period (a deployment and usage metric captured from mailing list archives) to be the best predictor of field defects. Our work identifies predictors of field defects in commonly available data sources for open source software systems and is a step towards metrics-based field defect prediction for quantitatively-based decision making regarding open source software components.","2005","2025-04-25 15:31:25","2025-04-25 15:31:25","","288-297","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.","2013-12","2025-04-25 15:31:25","2025-04-25 15:31:25","","361-370","","4","38","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.","2009-07-17","2025-04-25 15:31:25","2025-04-25 15:31:25","","","","","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper aims to explore the mechanism of knowledge sharing in OSS projects from the perspective of developers in China. A quantitative method with the analysis of 403 valid questionnaires is adopted. A series of hypotheses about how distributed innovation (independent variables) influences knowledge sharing (mediating variable) and then affects the performance of OSS projects (dependent variable) are tested and approved. On the one side, we argue that developers will actively affect knowledge sharing in terms of participative motivation, social network and organisational culture. On the other hand, users may also affect the knowledge sharing when considering innovation willingness and capacity. It is interesting to find that social network is the most important factor in Chinese cases. It is strongly recommended to strengthen the collaboration between software companies and OSS communities.","2017-01","2025-04-25 15:31:25","2025-04-25 15:31:25","","1-22","","1","29","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Celeris is an open source software which needs minimum preparation to run on a Windows machine. The software solves the extended Boussinesq equations using a hybrid finite volume finite difference method and supports moving shoreline boundaries. The simulation and visualization are performed on the GPU using Direct3D libraries, which enables the software to run faster than real-time. Celeris provides a first-of-its-kind interactive modeling platform for coastal wave applications and it supports simultaneous visualization with both photorealistic and colormapped rendering capabilities. We validate our software through comparison with three standard benchmarks for non-breaking and breaking waves. Program summary Program title: Celeris Program Files doi: http://dx.doi.org/10.17632/5djwvf5x5k.1 Licensing provisions: GNU General Public License 3 (GPL) Programming language: C++, HLSL Nature of problem: Boussinesq-type models provide the research-level accuracy needed for modeling wave propagation in coastal zones. However the current models, both commercial and open source, do not provide means for real-time computation, nor provide model interactivity and concurrent visualization. In order to achieve a real-time simulation speed in current parallelized models, dozens to hundreds of CPU cores are needed. Celeris is an interactive software which provides faster than real-time simulation and visualization speed on an average user laptop. The novelty of this software is its interactive environment, which allows the user to modify the model and field parameters as the model is running, and to see the effect of these changes immediately. Solution method: A hybrid finite volume-finite difference scheme is used to solve the extended Boussinesq equations. The solver is parallelized using shader programming with Direct3D libraries. Visualization is also performed with the same libraries. (C) 2017 Elsevier B.V.

We have developed a new generic software package for the solution of inverse problems implementing the Ensemble Smoother with Multiple Data Assimilation (genES-MDA). It is an open-source, platform-independent Python-based program. Its aim is to facilitate the management and configuration of the ES-MDA through several programming tools that help in the preparation of the different steps of ES-MDA. genES-MDA has a flexible workflow that can be easily adapted for the implementation of different variants of the ensemble Kalman filter and for the solution of generic inverse problems. This paper presents a description of the package and some application examples. genES-MDA has been tested in three synthetic case studies: the solution of the reverse flow routing for the estimation of the inflow hydrograph to a river reach using observed water levels and a calibrated forward model of the river system, the identification of a hydraulic conductivity field using piezometric observations and a known forward flow model, and the estimation of the release history of a contaminant spill in an aquifer from measured concentration data and a known flow and transport model. The results of all these tests have demonstrated the flexibility of genES-MDA and its capabilities to efficiently solve different types of inverse problems.","2022-10","2025-04-25 15:31:25","2025-04-25 15:31:25","","","","","167","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Motile cilia move fluid flow or propel cells, while also fulfill sensory functions. Primary cilia are immotile and act as a cellular antenna, translating environmental cues into cellular responses. Ciliary dysfunction leads to severe diseases, commonly termed ciliopathies. The molecular details underlying ciliopathies and ciliary function are, however, not well understood. Since cilia are small subcellular compartments, imaging-based approaches have been used to study them. However, tools to comprehensively analyze images are lacking. Automatic analysis approaches require commercial software and are limited to 2D analysis and only a few parameters. The widely used manual analysis approaches are time consuming, user-biased, and difficult to compare. Here, we present CiliaQ, a package of open-source, freely available, and easy-to-use ImageJ plugins. CiliaQ allows high-throughput analysis of 2D and 3D, static or time-lapse images from fluorescence microscopy of cilia in cell culture or tissues, and outputs a comprehensive list of parameters for ciliary morphology, length, bending, orientation, and fluorescence intensity, making it broadly applicable. We envision CiliaQ as a resource and platform for reproducible and comprehensive analysis of ciliary function in health and disease.","2021-02","2025-04-25 15:31:25","2025-04-25 15:31:25","","","","2","44","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is particularly challenging in Free and Open Source Software (FOSS) ecosystems, in which hundreds of loosely connected developers and their projects are coordinated to release software to a schedule. To better understand this process and its challenges, we analyzed over two and half years of communication in the GNOME ecosystem and studied developers' interactions. Through a case study, we cataloged communication channels, determined the main channel from which we categorized high level communication and coordination activities spanning five releases, and triangulated our results by interviewing ten key developers. We found that a release schedule, influence (instead of direct control), and diversity are the main factors that positively impact the release process in the GNOME ecosystem. We report a set of lessons learned that encapsulates our understanding of how the Release Management process function in a FOSS ecosystem, we learned that: (1) ensure that the release team follows the main communication channels used by developers, (2) provide a common place for coordination for an ecosystem, (3) consider including both good technical and social skills in a release team, (4) aim for a diverse release team, (5) based on lack of power, lobbying and consensus based management must be followed, (6) help the release team in the coordination process with a well defined schedule, and (7) release team work is different from regular software work. Our results can help organizations build better large-scale teams and show that research focused on individual projects might miss important parts of the picture.","2017-08-30","2025-04-25 15:31:25","2025-04-25 15:31:25","","","","","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-25 15:31:25","2025-04-25 15:31:25","","2366-2380","","","","","","","","","","","Assoc Comp Machinery; ACM SIGSAC; Huawei; Natl Sci Fdn; Technol Innovat Inst; Twenty Second Century Dora Technol; Ant Res; IBM; TikTok; Abelian; Input Outut","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this research was to evaluate milkweed floss as an insulative fill material and to compare its performance to other insulators. Seven identical jackets were constructed using different fill materials matched on a per unit weight basis. The insulation (clo) values for the jackets were measured using a standing, heated manikin in an environmental chamber. Thickness (loft), compression, resiliency, and hand were also measured. Several performance characteristics were evaluated before and after cleaning. The results show that milkweed floss blended with down has insulative properties similar to down. Down is superior to milkweed floss in loftiness and compressibility, which influence product performance, but the properties of milkweed floss can be enhanced by blending with down.","1991-04","2025-04-25 15:31:26","2025-04-25 15:31:26","","203-210","","4","61","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Finding an appropriate task to start with is a common entrance barrier for newcomers. Poor code quality contributes to difficulties in the onboarding process and limits contributor satisfaction in general. In turn, dissatisfied developers tend to exacerbate problems with system integrity. Poorly designed systems are difficult to maintain and extend. Users can often directly experience these issues as instabilities in system behavior. Thus code quality is a key issue for users and contributors in FOSS. We present a case study on the interactions between code quality and contributor experience in the real-world FOSS project Catrobat.

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.","2014","2025-04-25 15:31:26","2025-04-25 15:31:26","","401-412","","","","","","","","","","","Assoc Comp Machinery Special Interest Grp Software Engn; CVIC SE; NSF; Microsoft Res; Huawei; Neusoft; Siemens; Yonyou; Hong Kong Univ Sci & Technol; Google; Radica; Samsung Res Amer; IBM Res; TCL; CCC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The outliers were removed by the OCSVM (one-class support vector machine) model, and the unique mapping relationship between the strain value and the deformation variables (three directions of x-, y-, and z-axis) at each point was completed by a neural-network model. The test results show that the maximum error of the measuring point in the direction of the three coordinate axes: the x-axis is 2.01%, the y-axis is 29.49%, and the z-axis is 15.52%.

Therefore, organizations are increasingly becoming OSS adopters, either as a result of a strategic decision or because it is almost unavoidable nowadays, given the fact that most commercial software also relies at some extent in OSS infrastructure. The way in which organizations adopt OSS affects and shapes their businesses. Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. In this paper, we propose to model OSS adoption strategies using a goal-oriented notation, in which different actors state their objectives and dependencies on each other. These models describe the consequences of adopting one such strategy or another: which are the strategic and operational goals that are supported, which are the resources that emerge, etc. The models rely on an OSS ontology, built upon a systematic literature review, which comprises the activities and resources that characterize these strategies. Different OSS adoption strategy models arrange these ontology elements in diverse ways. In order to assess which is the OSS adoption strategy that better fits the organization needs, the notion of model coverage is introduced, which allows to measure the degree of concordance among every strategy with the model of the organization by comparing the respective models. The approach is illustrated with an example of application in a big telecommunications company. (C) 2015 Elsevier B.V.

There is an ever-present need for readily available information and sophisticated means of communication. As a result, information and communication technologies are being deployed for application in various fields of endeavour some of which include virtual offices. A virtual office is essentially a simulated corporate environment that gives subscribers access to collaborative work related features, which act as a means of improving the way work is carried out in an organisation. Several organisations opt for the software services rendered by virtual offices because of their cost effectiveness and tendency to boost the collective productivity of these organisations. For reasons as such, the existence of virtual office software suites have become rampant, but the availability of its services are at a cost. This paper reports the design and implementation of an Educational Virtual Office using Free and Open-Source Software (FOSS) to relieve corporate organisations of the costly burdens of existing proprietary virtual office software. Tools used in achieving this feat are Drupal Web Content Management System (WCMS), readily available FOSS and a couple of other freeware, intelligently integrated to form a composite suite. The developed educational virtual office suite was deployed in the Department of Electrical and Information Engineering of Covenant University. A usability (user satisfaction) test was conducted. Analysis of the test results showed that questions related to user satisfaction scored more “Strongly Agree” and “Agree” points than “Disagree” and “Strongly Disagree”. This is a pointer to the fact that features such as the GUI of the web application and its navigation proved to have little or no challenges as at when the tests were carried out.

Furthermore, some FOSS characteristics, such as (1) the advance of this movement and (2) the attractiveness that contributes the voluntary and cooperative work, have increased the interest of the users towards free software. Traditionally, research in FOSS has focused on identifying individual personal motives for participating in the development of a FOSS project, analyzing specific FOSS solutions, or the FOSS movement itself. Nevertheless, the advantages of the FOSS for users and the effect of the demographic dimensions on user acceptance for FOSS have been two research topics with little attention. Specifically, this paper's aim is to focus on the influence of the user experience with FOSS the FOSS acceptance.

We describe four active Education-Oriented H/FOSS projects and introduce a framework for illustrating different models of H/FOSS engagement. The framework is used to structure a discussion of the considerations and trade-offs of different engagement models, and highlights particular models that have been used to engage students and faculty in our four Education-Oriented H/FOSS projects. The framework positions projects along dimensions of professor involvement, responsibility for project hosting/management, mode of student knowledge and skill acquisition, and the curricular engagement goals. In doing so it broadly captures trade-offs that exist between the level of institutional resources used and the level of student independence required. It is anticipated this framework and the discussion that it organizes will be useful to faculty a) in evaluating the appropriateness of particular H/FOSS projects for use in their courses and curriculum and b) as guidance to those considering the creation of new Education-Oriented H/FOSS projects.","2023","2025-04-25 15:31:26","2025-04-25 15:31:26","","409-415","","","","","","","","","","","Assoc Comp Machinery; ACM Special Interest Grp Comp Sci Educ","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With recent trends such as mass customization or Industry 4.0, there is an increasing need for automation systems to be dynamic. Changing parts of the software of today's automation systems, however, typically requires rebooting the controller, which makes software updates a complex and costly endeavor often despised by operators. This article presents an approach to updating the software of automation systems at runtime without disrupting the system's operation. This is achieved with a combination of a component-based architecture, cyclic application execution, and a state transfer mechanism between the original and the updated version of a component. We validate our solution with a case study in which we update the control algorithm of a magnetic levitation device running at cycles of 1 kHz without dropping the ball.","2014","2025-04-25 15:31:27","2025-04-25 15:31:27","","","","","","","","","","","","","Univ Politecnica Catalunya; IEEE Ind Elect Soc; IEEE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Enhanced collaboration, ad hoc access to tools, data and high-performance processing facilities are some of the gains to be made. Scientific workflows are concerned with, amongst others, supporting the repeatability and provenance of experiments. In context of three sets of research (wildfire research, flood modelling and the linking of disease outbreaks to multi-scale environmental conditions), we describe our efforts to provide geospatial capability for scientific workflow software environments to support researchers in exploring, integrating and visualising earth observation and geographic data in conjunction with other research data. We note that functionalities for data ingest (raster and vector), data transformation (reprojection and simplification), data export and spatial overlay operations commonly are required. We find a relative lack of support for geospatial data, services and these functions within several Free and Open Source Software (FOSS) scientific workflow packages. Furthermore, we highlight some software development and data encoding challenges faced when utilising various FOSS geospatial libraries within these scientific workflow environments.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11-01","2025-04-25 15:31:27","2025-04-25 15:31:27","","597-625","","4","42","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use.

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails. These emails contain decisions for 466 Python Enhancement Proposals (PEPs) that document the language's evolution.

It allowed users to filter patient groups by 17 different criteria and investigate antimicrobial use, microbiological diagnostic use and results including antimicrobial resistance, and outcome in length of stay. Furthermore, with RadaR, results can be stratified and grouped to compare defined patient groups on the basis of individual patient features. Conclusions: AMS teams can use RadaR to identify areas within their institutions that might benefit from increased support and targeted interventions. It can be used for the assessment of diagnostic and therapeutic procedures and for visualizing and communicating analyses. RadaR demonstrated the feasibility of developing software tools for use in infection management and for AMS teams in an open-source approach, thus making it free to use and adaptable to different settings.","2019-06-11","2025-04-25 15:31:27","2025-04-25 15:31:27","","","","6","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This decision is partly justified by the difficulty of bringing real software projects to the classroom. The ubiquity of Open Source Software (OSS) projects contributes to mitigating this problem. Several instructors already make use of contribution to OSS as part of the teaching and evaluation process in their courses. However, little is known about how students perceive the approach of contributing to OSS projects in the context of a Software Engineering course. This paper aims to uncover challenges and benefits from the students' perspective. To achieve this, we conducted14 semi-structured interviews with students who attended to this kind of courses in five different Brazilian universities, resulting in findings not so well known. For example, we noticed that, although instructors point to the projects that students are required to contribute to, students (and the project community) are involved in the process of choosing projects and tasks (issues). We also identified that students' contributions vary in terms of number of lines added and removed in commits, as well as the use of different programming languages.","2018","2025-04-25 15:31:27","2025-04-25 15:31:27","","260-269","","","","","","","","","","","Faber Castell; B2W Digital; UOL; CeMEAI; Google; Univ Sao Paulo, Inst Ciencias Matematicas Computacao; Univ Fed Sao Carlos; Inst Fed Sao Paulo; IBM; Monitora","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The article examines how students, who were trained in OSS, are motivated to continue using it. A conceptual model based on Self-Determination Theory and the Technological Acceptance Model (TAM) was defined in order to test the behavioral intention to use OSS, comprising six constructs: (1) autonomy, (2) competence, (3) relatedness, (4) perceived ease of use, (5) perceived usefulness and (6) behavioral intention to use. A survey was designed for data collection. The participants were recent secondary school graduates, and all of them had received mandatory OSS training. A total of 352 valid responses were used to test the proposed structural model, which was performed using the Lisrel software. The results clearly confirmed the positive influence of the intrinsic motivations; autonomy and relatedness, to improve perceptions regarding the usefulness and ease of use of OSS, and; therefore, on behavioral intention to use OSS. In addition, the implications and limitations of this study are considered.","2020-02","2025-04-25 15:31:27","2025-04-25 15:31:27","","","","8","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Methods: CBCT scans were retrieved from endodontic records of two patients. Threedimensional virtual models, voxel counting, volumetric measurement (mm(3)) and mean intensity of the periapical lesion were performed with ITK-SNAP v. 3.0 software. Threedimensional models of the lesions were aligned and overlapped through the MeshLab software, which performed an automatic recording of the anatomical structures, based on the best fit. Qualitative and quantitative analyses of the changes in lesions size after treatment were performed with the 3DMeshMetric software. Results: The ITK-SNAP v. 3.0 showed the smaller value corresponding to the voxel count and the volume of the lesion segmented in yellow, indicating reduction in volume of the lesion after the treatment. A higher value of the mean intensity of the segmented image in yellow was also observed, which suggested new bone formation. Colour mapping and “point value” tool allowed the visualization of the reduction of periapical lesions in several regions. Conclusions: Researchers and clinicians in the monitoring of endodontic periapical lesions have the opportunity to use open-source software.","2016","2025-04-25 15:31:27","2025-04-25 15:31:27","","","","1","46","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, these models lack consensus between scholars as well as standard bodies on a specific set of usability evaluation criteria. Retaining irrelevant criteria and omitting essential ones will mislead the direction of the usability evaluation. Objective: This study introduces a three-step method to develop a usability evaluation model in the context of OSS. Method: The fuzzy Delphi method has been employed to unify the usability evaluation criteria in the context of OSS. The first step in the method is the usability criteria analysis, which involves redefining and restructuring all collected usability criteria reported in the literature. The second step is fuzzy Delphi analysis, which includes the design and validates the fuzzy Delphi instrument and the utilisation of the fuzzy Delphi method to analyse the fuzziness consensus of experts' opinions on the usability evaluation criteria. The third step is the proposal of the OSS usability evaluation model. Results: A total of 124 usability criteria were identified, redefined, and restructured by creating groups of related meaning criteria. The result of the groupings generated 11 main criteria; the findings of the fuzzy Delphi narrowed down the criteria to only seven. The final set of criteria was sent back to the panellists for reconsideration of their responses. The panellists verified that these criteria are suitable in the evaluation of the usability of OSS. Discussion: The empirical analysis confirmed that the proposed evaluation model is acceptable in assessing the usability of OSS. Therefore, this model can be used as a reference metric for OSS usability evaluation which will have a practical benefit for the community in public and private organisations in helping the decision-maker to select the best OSS software package amongst the alternatives.","2021-02","2025-04-25 15:31:27","2025-04-25 15:31:27","","","","","130","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key factor for the success of a free software project is its development dynamics, dependent on the attraction and retention of users and developers. The license plays an important role in this scenario, because by imposing restrictions on the use of the source code it attracts potential contributors in a different way. The degree of restriction of the license and an indicator of success of free software were related: the time between stages, that is, the time spent to evolve through the various stages of development. The results indicated that projects licensed under non-restrictive terms progress faster than projects licensed under highly restrictive terms and that projects with restrictive licenses progress slower than projects with non-restrictive or highly restrictive licenses.","2015","2025-04-25 15:31:28","2025-04-25 15:31:28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this sense, refactoring edits aim at improving structural aspects of a code without changing its external behavior. However, studies show that developers tend to combine in a single commit refactorings and behavior-changing edits (extra edits) - floss-refactoring. Floss-refactorings can be error-prone and require careful handling. However, little has been done to understand how refactorings and extra edits relate in practice. In this work, we propose a strategy for extracting floss-refactoring data. Moreover, we mine code repositories of 16 open-source projects and analyse commits with floss refactoring related to Extract Method. Our results show that developers often combine Extract Method with inner method extra edits (e.g., statement insert), with an expected increase of 8-16% of extra edits by each Extract Method. Moreover, some statements are more likely to be changed depending on the extra edit performed.","2020","2025-04-25 15:31:28","2025-04-25 15:31:28","","1532-1539","","","","","","","","","","","ACM; Masaryk Univ Czechia; Microsoft Res; ACM Special Interest Grp Appl Comp; Natl Inst Technol Calicut","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The produced material is basically made up of videos together with appropriate explanatory comments that show how to estimate and validate a general linear model by using specialized econometric software. The election of the econometric packages Gretl and R is not arbitrary but responds to the need to provide to students reliable tools that may be freely used in their professional future without being subject to licensing fees. The main goal is to focus on the learning process in the students providing them more than only pages filled with formulas (often incomprehensible to the student).

The extracted cellulose had mainly a-cellulose as the other components hemicellulose and lignin were significantly removed during cellulose extraction process. The FTIR spectra also indicated that the chemical treatments extensively removed hemicellulose and lignin from the pristine milkweed floss. SEM technique was used to investigate the surface morphology of the pristine milkweed floss and extracted cellulose. The intensity of the crystalline peak in the X-ray diffractograms of the extracted cellulose was higher than that of pristine milkweed. Further, the XRD results indicated a structural transformation of cellulose I (pristine milkweed) to cellulose II (extracted cellulose) because of the chemical treatments. The extracted cellulose, which is a high biomass, had better thermal stability than the pristine milkweed floss owing to removal of non-cellulosic components.","2017","2025-04-25 15:31:28","2025-04-25 15:31:28","","2677-2683","","17","52","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We consider: the variability of mathematical representation techniques on which the theoretical foundations of formal methods are based; formal methods multidisciplinarity; their capability to serve at a meta-level in providing the semantics of programming languages, specification and modelling languages as well as higher- level and domain-specific formal notations; and, finally, how some of these higher-level and domain-specific notations may be lifted at an interdisciplinary level. Within this historical review, we are inspired by Luis Barbosa's “components as coalgebras” approach in seeing that the duality data-process is underlying all those aspects of formal methods. We also see that such a duality may not only be expressed in universal terms within category theory, but may also be characterised in practical terms and focused applications by two distinct logic paradigms, equational logic for the data and rewriting logic for the process, by two modelling directions, forward process definitions and backward data-driven process transformations, and by the distinction between syntax, defined by the data structures, and semantics, provided by rewrite rules. We use the Maude modelling language to illustrate the application of the data- process duality. In fact, Maude use equational logic to define data types and rewriting logic to express system evolution. Illustrative examples are from the areas of cognitive science and human- computer interaction (HCI). We then define a data-driven model transformation, which we call elaborative mining, , which adopts a backward perspective to recover a behaviour that was observed in real life but was not predicted forward by the original model. Finally, we see how the “open source software bazaar”, which is a metaphor for the apparently chaotic open source development process, offers us a big data context to lift the driving process for model transformation from deterministic to statistical.","2025-01","2025-04-25 15:31:28","2025-04-25 15:31:28","","","","","142","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We used the following theoretical foundations: ludic narratives and video games, digital reading in a hybrid context (coexistence of paper and screen) and free software in education. The data collected were analyzed with grounded theory procedures to construct the following categories of analysis of the digital reading comprehension of children: literal comprehension, inferential comprehension, inferential comprehension of literary elements and comprehension of the ludic structure and.

Documenting and disseminating the public works heritage have now come of age, digitally speaking, with the adoption of new technologies both to further research on and heighten the esteem attributed to the public works heritage. Nonetheless, academic discourse rarely describes procedures for the 3D digitisation of heritage works comprehensible to non-expert readers with limited resources. Taking that premise as a starting point, with special attention to the determinants of the public works heritage, this article aims to define the general, open-source methodology covering 3D model data capture, information processing and optimisation. The article also discusses model dissemination strategies using free platforms and low-cost tools. The general discussion is illustrated with the case study of Ariza Bridge in Spain. This Renaissance-style structure dates from the second half of the sixteenth century. Despite its listing as a cultural heritage asset, the monument was flooded by the Giribaile reservoir waters in 1998 and is now only wholly visible during droughts. The application, developed with open-source software and implemented with free platforms and low-cost tools, features geo-referencing and is designed to be accessible to non-expert users. The methodology proposed is intended as a suitable instrument for the sustainable study, valorisation and dissemination of the built heritage.","2021-12","2025-04-25 15:31:28","2025-04-25 15:31:28","","","","23","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Addressing a significant knowledge gap affecting this structural type, the study reveals how daily and seasonal fluctuations in environmental factors have a notable influence on its experimental modal parameters. A robust frequency-domain tracking algorithm is first developed to identify and follow the evolution of modal parameters over time, exploiting ambient vibration recordings acquired at sub-daily intervals on the structures. The procedure is systematically applied to the entire portfolio of case-study buildings and, in the first year of training, integrated with measurements of environmental parameters provided by nearby weather stations. The multivariate regression analysis indicates that temperature variation is the primary driver of the observed wandering of natural frequencies. The frequency-temperature relationship shows a positive correlation above zero degrees and, in several cases, a significant degree of nonlinearity already present in low-frequency global modes. Simple predictive models are proposed to address such nonlinear behavior, including freezing conditions and accounting for internal heating during winter. Leveraging these novel insights, the work develops strategies to improve the efficiency of data acquisition protocols and training periods, enabling the near-future extension of real-time condition assessment methodologies to the entire OSS network.","2024-09-10","2025-04-25 15:31:28","2025-04-25 15:31:28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The halloysite-mediated satellite-core material displays a photocatalytic of H-2 evolution performance with the highest evolution rate of 137.0 mu mol g(-1) h(-1) in visible light condition with no co-catalysts, and is similar to 3.4 times that of bulk g-C3N4, mainly benefiting from the reduced nanometer size of debris g-C3N4 and enhanced interface dispersion ability by HNTs, resulting in ameliorative separation efficiency of photogenerated charge carriers.

First, this study is based on ethnographic research of free software projects and uses the resulting thick description to determine the meaning of sharing in this context. Second, the current literature on sharing usually takes user-generated content (UGC) platforms as its empirical reference, resulting in identifying a distinct meaning of sharing in this context. By combining the two sets of findings into a single narrative, this study makes three points: (1) the academic discourse on free software conceptualizing it as a form of gift-giving antithetical to the ways of capitalist production needs to be revised; (2) the use of sharing in the context of UGC platforms relies heavily on references to the culture of free software; (3) although representatives from both contexts claim to be taking part in the same sharing practices, there are substantial differences in the type of information being shared, the explicitness of the sharing mechanisms, and the organizational context of monetization of the shared objects.","2019","2025-04-25 15:31:28","2025-04-25 15:31:28","","1295-1309","","9","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Organizations adopt OSS in very diverse ways. The way in which they adopt OSS affects and shapes their businesses. Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. However, there is a lack of support for assessing the impact of the OSS adoption over the business of the adopter organizations. Based on the goal-oriented characterization of some OSS adoption strategies, in this paper, we propose a preliminary approach to assess the business impact of the OSS adoption strategies over the adopter organizations. The proposal is based on the Business Model Canvas and graph theory notions to support the elicitation and assessment of the impact of each goal over the adopter organization. We illustrate the application of the approach in the context of a telecommunications company.","2015","2025-04-25 15:31:28","2025-04-25 15:31:28","","289-305","","","235","","","","Lecture Notes in Business Information Processing","","","","IFIP WG 8 1","","","","","","","","","ISSN: 1865-1348","","","","","","Ralyte, J; Espana, S; Pastor, O","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, identifying a project appropriate for student involvement can be a difficult task. There are a huge number of possible FOSS projects with a wide range of sizes, complexity, and domains. The presenters of this workshop have developed an approach to FOSS project identification [1] which is based on several years of experience with student participation in FOSS projects. The approach is based on humanitarian FOSS (HFOSS) as those projects have been shown to motivate students [2].

For example, maintainers help lead the project and promote its longevity, technical writers assist with documentation, bug reporters identify defects in software, and developers program the software. However, it is unknown which skills are used in OSS development as well as OSS contributors' general attitudes towards skills in OSS. In this paper, we address this gap by administering a survey to a diverse set of 455 OSS contributors. Guided by these responses as well as prior literature on software development expertise and social factors of OSS, we develop a model of skills in OSS that considers the many contexts OSS contributors work in. This model has 45 skills in the following 9 categories: technical skills, working styles, problem solving, contribution types, project-specific skills, interpersonal skills, external relations, management, and characteristics. Through a mix of qualitative and quantitative analyses, we find that OSS contributors are actively motivated to improve skills and perceive many benefits in sharing their skills with others. We then use this analysis to derive a set of design implications and best practices for those who incorporate skills into OSS tools and platforms, such as GitHub.","2022","2025-04-25 15:31:29","2025-04-25 15:31:29","","170-182","","","","","","","","","","","Assoc Comp Machinery; ACM SIGSOFT; Natl Univ Singapore; Sea Ltd; Amazon Web Serv; Dragon Testing; Microsoft Res; Ant Grp; Google; Meta; Naver; Huawei; Zilliqa; KAIST","","","","","","","","","","","","","","","Roychoudhury, A; Cadar, C; Kim, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To reach this aim, we designed the structure of the dataset by studying OSS characteristics and we mined both SourceForge and Github repositories in order to constitute the data collection. We then proceeded to the evaluation step by running a set of well-known recommendation algorithms within Recommender101 and Librec frameworks on the OSS dataset.

However, the stages when developers leave the projects are still weakly explored and are not well-defined in existing developers' lifecycle models. In this position paper, we enrich the knowledge about the leaving stage by identifying sleeping and dead states, representing temporary and permanent brakes that developers take from contributing. We conducted a preliminary set of semi-structured interviews with active developers.

The network of `communities' emerging from this analysis links sub-groups of densely connected developers, sub-groups that are smaller than the components of the network but larger than the teams working on single projects. Our results reveal the complexity of this meso-level structure, where several dense sub-groups of developers are connected by sparse collaboration among different sub-groups. We discuss the theoretical implications of our findings with reference to the wider literature on collaboration networks and potential for innovation.

The problems we faced were the lack of a centralized user management, insufficient scaling of our communication channels, and the necessity to adapt agile development techniques to remote collaboration. To solve the problems we decided to use a mix of open source tools (Git, IRC, LDAP) and commercial solutions (Jira, Confluence, GitHub) because we believe that this mix best fits our needs. Other projects can benefit from the lessons we learned during the reorganization of our knowledge base and communication tools, as infrastructure changes can be very labor-intensive and time-consuming.","2015","2025-04-25 15:31:29","2025-04-25 15:31:29","","13-22","","","451","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 2 13; Google","","","","","","","","","ISSN: 1868-4238","","","","","","Damiani, E; Frati, F; Riehle, D; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have extensively studied the human aspects of the OSS paradigm from the point of view of community formation to community evolution. A few studies relate community dynamics with OSS product attributes such as code quality. However, the impact of community dynamics on non-code contributions such as commits has not been explored. In this paper, the aim is to analyze the impact of community dynamics on syntactic quality of commit messages of an OSS project. We first propose and validate a commit message quality model, and then use that model to analyze the OSS projects. Empirical analysis of seven OSS projects available in the Git repository shows that a small group of contributors active at the same time in a project leads to high syntactic quality contributions. These observations may prove useful to developers as well as project managers who need quantifiable techniques for monitoring the OSS projects.","2018","2025-04-25 15:31:30","2025-04-25 15:31:30","","61-76","","","525","","","","IFIP Advances in Information and Communication Technology","","","","Harokopio Univ; IFIP WG 2 13","","","","","","","","","ISSN: 1868-4238","","","","","","Stamelos, I; GonzalezBarahona, JM; Varlamis, I; Anagnostopoulos, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The effect of this shift on project organization and developer collaboration is not well understood. In this paper, we use a theoretical argument to evaluate the appropriateness of using DVC in the context of two very common organization forms in OSS: a dictatorship and a peer group. We find that DVC facilitates large hierarchical communities as well as smaller groups of developers, while CVC allows for consensus-building by a peer group. We also find that the flexibility of DVC systems allows for diverse styles of developer collaboration. With CVC, changes flow up and down (and publicly) via a central repository. In contrast, DVC facilitates collaboration in which work output can flow sideways (and privately) between collaborators, with no repository being inherently more important or central. These sideways flows are a relatively new concept. Developers on the Linux project, who tend to be experienced DVC users, cluster around “sandboxes:” repositories where developers can work together on a particular topic, isolating their changes from other developers. In this work, we focus on two large, mature OSS projects to illustrate these findings. However, we suggest that social media sites like GitHub may engender other original styles of collaboration that deserve further study.","2013","2025-04-25 15:31:30","2025-04-25 15:31:30","","29-32","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, this expansion has also brought significant security challenges, particularly introducing and propagating software vulnerabilities. Despite the use of machine learning and formal methods to tackle these issues, there remains a notable gap in comprehensive surveys that summarize and analyze both Vulnerability Detection (VD) and Security Patch Detection (SPD) in OSS. This article seeks to bridge this gap through an extensive survey that evaluates 127 technical studies published between 2014 and 2023, structured around the Vulnerability-Patch lifecycle. We begin by delineating the six critical events that constitute the Vulnerability-Patch lifecycle, leading to an in-depth exploration of the Vulnerability-Patch ecosystem. We then systematically review the databases commonly used in VD and SPD, and analyze their characteristics. Subsequently, we examine existing VD methods, focusing on traditional and deep learning based approaches. Additionally, we organize current security patch identification methods by kernel type and discuss techniques for detecting the presence of security patches. Based on our comprehensive review, we identify open research questions and propose future research directions that merit further exploration.","2025-01","2025-04-25 15:31:30","2025-04-25 15:31:30","","","","1","57","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bioinformatics, a core component of omics research, is one of the disciplines that first employed Free/Libre Open Source Software (FLOSS), and thus provided a fertile ground for its further development. Understanding the use and characteristics of FLOSS deployed in the omics field is valuable for future innovation strategies, policy and funding priorities. We conducted a bibliometric, longitudinal study of the use of FLOSS in sepsis omics research from 2011 to 2015 in the United States, EU-28 and China. Because sepsis is an interdisciplinary field at the intersection of multiple omics technologies and medical specialties, it was chosen as a model innovation ecosystem for this empirical analysis, which used publicly available data. Despite development of and competition from proprietary commercial software, scholars in omics continue to employ FLOSS routinely, and independent of the type of omics technology they work with. The number of articles using FLOSS increased significantly over time in the EU-28, as opposed to the United States and China (R=0.96, p=0.004). Furthermore, in an era where sharing of knowledge is being strongly advocated and promoted by public agencies and social institutions, we discuss possible correlations between the use of FLOSS and various funding sources in omics research. These observations and analyses provide new insights into the use of FLOSS in sepsis omics research across three (supra)national regions. Further benchmarking studies are warranted for FLOSS trends in other omics fields and geographical settings. These could, in time, lead to the development of new composite innovation and technology use metrics in omics systems sciences and bioinformatics communities.","2018-05","2025-04-25 15:31:30","2025-04-25 15:31:30","","365-372","","5","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For such software development paradigm, how to evaluate the skills of the developers comprehensively and automatically is critical. However, most of the existing researches assess the developers based on the “Implementation” aspects, such as the artifacts they created or edited. They ignore the developers' contributions in “Social collaboration” aspects, such as answering questions, giving advices, making comments or creating social connections. In this paper, we propose a novel model which evaluate the individuals' skills from both “Implementation” and “Social collaboration” aspects. Our model defines four metrics from muti-dimensions, including collaboration index, technical skill, community influence and development contribution.

In an earlier article, a proof-of-concept for a computer-aided visualization tool (also named STEVE, version 1.0) for stochastic theory education in water resources engineering was articulated [see, Schwenk et al. Comput. Appl. Eng. Educ., 2008, in press). Using lava Native Interfacing, it was shown that STEVE 1.0 could wrap a space time stochastic model written in any computer language and be independent of any specific language compiler during tool usage. This article describes the general philosophy, software design, and classroom usage for STEVE with significant improvements on visualization and user-friendliness (hence, rightfully called version 2.0). The software was created using the C++ programming language with the Microsoft Windows Applications Programming Interface (API). OpenGL was used for the visualization display, and the OpenGL Utility Toolkit (GLUT) was used to visualize text inside the OpenGL window. The instructor-specified simulation program on stochastic theory was written in Fortran 77. The application has user-friendly options for modifying input data and parameter specifications as desired by the instructor or the student user. STEVE 2.0 has been tested with the Windows XP and Windows Vista operating systems. For the benefit of interested users and software makers, we also provide the software application, a short tutorial and all pertinent source codes as freeware for download on our STEVE homepage at http://iweb.tntech.edu/saswe/steve.html.

The sensor, based on instantaneous measurements, functions as a position server for dual-axis solar trackers in photovoltaic plants. The proposed device has been developed with free software and hardware, which makes it a pioneering solution because it is open and accessible as well as capable of being improved by the scientific community, thereby contributing to the rapid advancement of technology. In addition, the device includes an algorithm developed ex professo that makes it possible to predetermine the regions of the celestial sphere for which, according to the geometric characteristics of the PV plant, there would be shading between the panels. In this way, solar trackers do not have to locate the Sun's position at all times according to astronomical models, while taking into account factors such as shadows or cloudiness that also affect levels of incident irradiance on solar collectors. Therefore, with this device, it is possible to provide photovoltaic plants with dual-axis solar tracking with a low-cost device that helps to optimise the trajectory of the trackers and, consequently, their radiative capture and energy production.","2021-02","2025-04-25 15:31:30","2025-04-25 15:31:30","","","","3","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of model organisms, the data available are numerous, given the degree of redundancy in the deposited EST data. There are several available bioinformatics tools that can be used to mine this data; however, using them requires a certain level of expertise: the tools have to be used sequentially with accompanying format conversion and steps like clustering and assembly of sequences become time-intensive jobs even for moderately sized datasets. We report here a pipeline of open source software extended to run on multiple CPU architectures that can be used to mine large EST datasets for SNPs and identify restriction sites for assaying the SNPs so that cost-effective CAPS assays can be developed for SNP genotyping in genetics and breeding applications. At the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the pipeline has been implemented to run on a Paracel high-performance system consisting of four dual AMD Opteron processors running Linux with MPICH. The pipeline can be accessed through user-friendly web interfaces at http://hpc.icrisat.cgiar.org/PBSWeb and is available on request for academic use. We have validated the developed pipeline by mining chickpea ESTs for interspecies SNPs, development of CAPS assays for SNP genotyping, and confirmation of restriction digestion pattern at the sequence level.

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.","2018-05","2025-04-25 15:31:30","2025-04-25 15:31:30","","","","5","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research seeks to address the existing gap in accessible tools for high-throughput analysis of endothelial tube formation and cell invasion in vitro, facilitating the rapid assessment of drug sensitivity.MethodsOur approach involved annotating over 1000 2 mm Z-stacks of cancer and endothelial cell co-culture model and training machine learning models to automatically calculate cell coverage, cancer invasion depth, and microvessel dynamics. Specifically, cell coverage area was computed using focus stacking and Gaussian mixture models to generate thresholded Z-projections. Cancer invasion depth was determined using a ResNet-50 binary classification model, identifying which Z-planes contained invaded cells and measuring the total invasion depth. Lastly, microvessel dynamics were assessed through a U-Net Xception-style segmentation model for vessel prediction, the DisPerSE algorithm to extract an embedded graph, then graph analysis to quantify microvessel length and connectivity. To further validate our software, we reanalyzed an image set from a high-throughput drug screen involving a chemotherapy agent on a 3D cervical and endothelial co-culture model. Lastly, we applied this software to two naive image datasets from coculture lumen and microvascular fragment models.ResultsThe software accurately measured cell coverage, cancer invasion, and microvessel length, yielding drug sensitivity IC50 values with a 95% confidence level compared to manual calculations. This approach significantly reduced the image processing time from weeks down to h. Furthermore, the software was able to calculate cell coverage, microvessel length, and invasion depth from two additional microphysiological models that were imaged with confocal microscopy, highlighting the versatility of the software.ConclusionsOur free and open source software offers an automated solution for quantifying 3D cell behavior in microphysiological models assessed using non-confocal microscopy, providing the broader Cellular and Molecular Bioengineering community with an alternative to standard confocal microscopy paired with proprietary software.This software can be found in our GitHub repository: https://github.com/fogg-lab/tissue-model-analysis-tools.","2024-10-10","2025-04-25 15:31:30","2025-04-25 15:31:30","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A large number of studies are published on different aspects of OSS evolution. Different metrics, models, processes and tools are presented for predicting the evolution of OSS studies. These studies foster researchers for contemporary and comprehensive review of literature on OSS evolution prediction. We present a systematic mapping that covers two contexts of OSS evolution studies conducted so far, i.e., OSS evolution prediction and OSS evolution process support. We selected 98 primary studies from a large dataset that includes 56 conference, 35 journal and 7 workshop papers. The major focus of this systematic mapping is to study and analyze metrics, models, methods and tools used for OSS evolution prediction and evolution process support. We identified 20 different categories of metrics used by OSS evolution studies and results show that SLOC metric is largely used. We found 13 different models applied to different areas of evolution prediction and auto-regressive integrated moving average models are largely used by researchers. Furthermore, we report 13 different approaches/methods/tools in existing literature for the evolution process support that address different aspects of evolution.","2017-08","2025-04-25 15:31:30","2025-04-25 15:31:30","","3465-3502","","8","42","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS. These results suggest that an inter-family succession of Betaproteobacteria occurred in response to colonization by mosses, followed by plants.","2019-09-25","2025-04-25 15:31:30","2025-04-25 15:31:30","","268-277","","3","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to detect types, and establish similarities, among Free/Libre/Open Source Software (FLOSS) systems, this paper considers three modular characteristics (functions, files and folders) and their evolution: how they are evolving with size, if they are constant across systems, and whether recurring evolutionary patterns are observed. Using these various-grained characteristics, a set of models for the evolution of modularization are extracted from evolving systems, and then used to extract similarities and types from a wide sample of FLOSS projects. This paper provides three contributions: first, it shows that several models are needed to encompass the variety of modularization patterns; second, it provides three types of models (uni-variate, bi-variate and tri-variate) for the evolution of modularization, with significant goodness-of-fit's. Finally, it shows that two of these patterns alone can interpolate the modular characteristics of the vast majority of a random choice of FLOSS projects.","2009","2025-04-25 15:31:30","2025-04-25 15:31:30","","3-19","","","299","","","","International Federation for Information Processing","","","","IFIP WG 2 13","","","","","","","","","ISSN: 1571-5736","","","","","","Boldyreff, C; Crowston, K; Lundell, B; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

From large technology companies to startups, companies are participating in the OSS ecosystem by open-sourcing their technology, sponsoring projects through funding or paid developer time. However, our understanding of the OSS ecosystem is rooted in the “old world” model where individual contributors sustain OSS projects. In this work, we create a more comprehensive understanding of the hybrid OSS landscape by investigating what motivates companies to contribute and how they contribute to OSS. We conducted interviews with 20 participants who have different roles (e.g., CEO, OSPO Lead, Ecosystem Strategist) at 17 different companies of different sizes from large companies (e.g. Microsoft, RedHat, Google, Spotify) to startups. Data from semi-structured interviews reveal that company motivations can be categorized into four levels (Founders' Vision, Reputation, Business Advantage, and Reciprocity) and companies participate through different mechanisms (e.g., Developers' Time, Mentoring Time, Advocacy & Promotion Time), each of which tie to the different types of motivations. We hope our findings nudge more companies to participate in the OSS ecosystem, helping make it robust, diverse, and sustainable.","2023","2025-04-25 15:31:31","2025-04-25 15:31:31","","2617-2629","","","","","","","International Conference on Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; Melbourne Convent Bur; State Govt Victoria; CSIRO; Huawei; Monash Univ; Meta; Google; AWS; Monash Univ; Dragon Testing Technol; IBM; Univ Melbourne; RMIT Univ","","","","","","","","","ISSN: 0270-5257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We foresee increasing costs for data collection and maintenance, leading to the risk of development budgets eaten up by commodity features, thus leaving little resources for differentiation and innovation. We therefore propose Open Collaborative Data (OCD) - a concept analogous to Open Source Software (OSS) as a means to share data. In contrast to Open Data (OD), which e.g., governmental agencies provide to catalyze innovation, OCD is shared in open collaboration between commercial organizations, similar to OSS. To achieve this, there is a need for technical infrastructure (e.g., tools for version and access control), licence models, and governance models, all of which have to be tailored for data. However, as data may be sensitive for privacy, anonymization and obfuscation of data is also a research challenge. In this paper, we define the concept of Open Collaborative Data, demonstrate it by map data and image recognition examples, and outline a research agenda for OCD in software engineering as a basis for more efficient evolution of software systems.","2019","2025-04-25 15:31:31","2025-04-25 15:31:31","","25-28","","","","","","","","","","","IEEE; Assoc Comp Machinery; IEEE CS; IEEE CS Tech Comm Software Engn; Assoc Comp Machinery Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif; ING; Natl Sci & Engn Res Council Canada; Prompt","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Empirical software engineering researchers can mine the artifacts from these tools to better understand how FLOSS is made. As the landscape of distributed software development has grown and changed, the tools needed to make FLOSS have changed as well. There are three newer tools at the center of FLOSS development today: distributed version control based forges (like Github), programmer question-and-answer communities (like Stack Overflow), and pastebin tools (like Gist or Pastebin.com). These tools are extending and changing the toolset used for FLOSS development, and redefining what a software forge looks like.

This quality and suitability is achieved through an elaborate peer-review process performed by a large community of users, who act as co-developers to identify and correct software defects and add features. Although this process is crucial to the success of free software projects, there is more to the free software development than the creation of a `bazaar'. In this paper we draw on existing free software projects to define a lifecycle model for free software. This paper then explores each phase of the lifecycle model and agrees that, while the bazaar phase attracts the most attention, it is the initial modular design that accommodates diverse interventions. Moreover, it is the period of transition from the initial group to the larger community based development that is crucial in determining whether a free software project will succeed or fail.","2004","2025-04-25 15:31:31","2025-04-25 15:31:31","","84-91","","","","","","","","","","","Korea Informat Sci Soc; Korea Soc Engn Fdn; Samsung Elect; Samsung SDS; LG Elect; Korea IT Ind Promto Agcy; Elect & Telecommun Res Inst","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Among these principles, “Brooks' Law” has been questioned in the Free Software context: large teams of developers, contrary to the law, will not need an increasingly growing number of communication channels. As advocates claim, this is due to the internal characteristics of the Free Software process: the high modularity of the code helps developers to work on comparted sections, without the need to coordinate with all other contriutors. This paper examines Brooks' Law in a Free Software context, and it studies the interaction of contributors to a large Free Software project, KDE. The network of interactions is analyzed and a summary term, the “compaction”, is dynamically evaluated to test how the coordination mechanism evolves over time in the project. This paper argues that the claim of advocates holds true, but with limitations: in the KDE project, the few initial developers needed a significant amount of communication. The growth of KDE brought the need to break the number of overall communication channels to a significant extent. Finally, an established amount of 300 developers currently needs the same amount of communication as when the developers were only 10. We interpret this result by arguing that Brooks' Law holds true among the core developers of any large Free Software project.","2009","2025-04-25 15:31:31","2025-04-25 15:31:31","","274-283","","","299","","","","International Federation for Information Processing","","","","IFIP WG 2 13","","","","","","","","","ISSN: 1571-5736","","","","","","Boldyreff, C; Crowston, K; Lundell, B; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The modeling approach considers residual gravity field functionals generated by the well-known remove-compute-restore (RCR) technique where the long and short wavelength parts of the gravity signal are provided by a global geopotential model (GGM) and digital terrain model (DTM), respectively. A new data-adaptive network design methodology called k-SRBF is used to construct a network of SRBFs. The appropriate bandwidths (depths) are chosen using the generalized cross-validation (GCV) technique. The unknown SRBFs coefficients are estimated by applying the least-squares method where the extended Gauss Markov Model (GMM) with additional prior information is applied if the normal equation matrix is ill-conditioned. In such a case, the optimal regularization parameter is determined by variance component estimation (VCE). By utilizing parallel processing in every stage of the RCR technique, including creating the design matrix, the computational time is remarkably decreased relative to the number of processors used in the modeling. The performance of the software has been tested and validated in the Auvergne test area (France) on the basis of real terrestrial gravity data. The differences between estimated and observed height anomaly points (GNSS/leveling) amount to about 3 cm in terms of standard deviation (STD) for all kernels indicating that the SRBF_Soft possesses the capability to be applied in regional gravity field modeling as an efficient and reliable software.","2022-06","2025-04-25 15:31:32","2025-04-25 15:31:32","","1341-1353","","2","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper is to discover the individualized contribution features of developers by latent Dirichlet allocation (LDA) approach. Dominant latent topics of each developer and the corresponding topic coverage degree are extracted from the source codes committed to the project repository, and such topic model is validated to be feasible for representing the individualized contribution features by statistics tests. Four types of topic evolution patterns are observed from the commit history of a developer. Temporal locality is partially exhibited in the topic evolution but there usually exhibit drastic changes between time-adjacent contributions of a developer. Respective proportions of the four evolution patterns and the degree of temporal locality in the topic evolution delineate a developer's individualized working habits in the time dimension. It is also proved that the correlation among the topic models of different developers is not equivalent to the real social collaborations among them. The outcome of this study would help OSS project coordinators get deep understanding on the work preferences and behavioral patterns of team members, thus facilitate project coordination activities such as task allocations.","2017-02","2025-04-25 15:31:32","2025-04-25 15:31:32","","91-124","","1","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To address the research gap, we conduct an empirical study based on the 5W1H model and data mining from five popular OSS projects on GitHub. We find that links originating from a PR are more common than the other three types of links, and links are more frequently created in Documentation. We also find that average duration between development units' create time in a link is half a year.

-"JKQX2PER","conferencePaper","2002","Spadaro, P","Sediment sequential risk mitigation at Thea Foss Waterway Superfund Site","MANAGEMENT OF CONTAMINATED SEDIMENTS","1-57477-128-0","","","","Sequential risk mitigation is a three-phase process designed to: (1) reduce the ecological and human health risks posed by highly contaminated sediments through confinement or capping; (2) reduce the risks associated with moderate levels of pollution on a less urgent schedule and at lower cost; and (3) address areas of limited contamination through a combination of natural attenuation and enhanced natural attenuation. Natural attenuation has as its basis the observation that ecosystem recovery appears to be largely a function of time. Sediment decomposition and the mixing of old sediments by bottom-dwelling organisms contribute to reduced contaminant concentrations. Knowledge of these processes is critical to the development of ecosystem recovery and waste management strategies. To evaluate the applicability of natural attenuation, information should be collected to determine whether surface sediment chemical concentrations will reach cleanup standards within a 10-year period through a combination of natural attenuation and adequate source control. The remedial design for the Thea Foss Waterway Superfund Site in Tacoma, Washington, employs the sequential risk mitigation approach. The EPA has selected a remedy involving natural attenuation (21 acres [8.4 hectares]), enhanced natural attenuation (4 acres [1.6 hectares]), dredging (650,000 cubic yards [494,000 cubic meters]), and capping (30 acres [12 hectares]) of this 8,000-foot (2,438-meter)-long waterway. The dredged material will be disposed of in a near-shore confined disposal facility. Specialized design elements include sorbent capping of active oil seeps, about 400 feet (122 meters) of permanent sheet pile bulkhead, and other features related to long-term monitoring of the remedy and to controlling contaminant sources.","2002","2025-04-25 15:31:32","2025-04-25 15:31:32","","201-209","","","","","","","","","","","Battelle Geneva Res Ctr; Azienda Multiservizi Ambientali Veneziana","","","","","","","","","","","","","","","Porta, A; Hinchee, RE; Pellei, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The aim of this research is to 1) identify what should be learnt about software development through regular participation in a FLOSS project/community, and 2) assess the didactic potential of this kind of non-standard learning experiences. To this aim we resorted to a participatory research action approach and qualitative methods, namely case studies combining direct observation and interviews.","2013","2025-04-25 15:31:32","2025-04-25 15:31:32","","208-214","","","8224","","","","Lecture Notes in Computer Science","","","","","","","","","","","","","ISSN: 0302-9743","","","","","","Antunes, P; Gerosa, MA; Sylvester, A; Vassileva, J; DeVreede, GJ","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The spread of diseases like influenza depends on the mixing patterns within the population, and these mixing patterns depend in part on local factors including the spatial distribution and age structure of the population, the distribution of size and composition of households, employment status and commuting patterns of adults, and the size and age structure of schools. Finally, public health planners must take into account the health behavior patterns of the population, patterns that often vary according to socioeconomic factors such as race, household income, and education levels. Results: FRED (a Framework for Reconstructing Epidemic Dynamics) is a freely available open-source agent-based modeling system based closely on models used in previously published studies of pandemic influenza. This version of FRED uses open-access census-based synthetic populations that capture the demographic and geographic heterogeneities of the population, including realistic household, school, and workplace social networks. FRED epidemic models are currently available for every state and county in the United States, and for selected international locations. Conclusions: State and county public health planners can use FRED to explore the effects of possible influenza epidemics in specific geographic regions of interest and to help evaluate the effect of interventions such as vaccination programs and school closure policies. FRED is available under a free open source license in order to contribute to the development of better modeling tools and to encourage open discussion of modeling tools being used to evaluate public health policies. We also welcome participation by other researchers in the further development of FRED.","2013-10-08","2025-04-25 15:31:32","2025-04-25 15:31:32","","","","","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The transformation of the measured reflection coefficient to complex permittivity is performed based on three different methods. The software library contains the dielectric spectra of common reference liquids, which can be used to transform the reflection coefficient into the dielectric spectra. Several Python routines that are commonly employed (e.g., SciPy and NumPy) in the field of science and engineering are required only so that the users can alter the software structure depending on their needs. The modeling algorithm exploits the Markov Chain Monte Carlo method for the data regression. The discrete relaxation models can be built by a proper combination of well-known relaxation models. In addition to these models, electrode polarization, a typical measurement artifact for interpreting dielectric spectra, can be incorporated into the modeling algorithm. A continuous relaxation model, which solves the Fredholm integral equation of the first kind (a mathematically ill-posed problem), is also included. This open-source software enables users to freely adjust the physical parameters to obtain physical insight into their materials under test and will be consistently updated for more accurate measurement and interpretation of dielectric spectra in an automated manner. This work describes the theoretical and mathematical background of the software, lays out the workflow, and validates the software functionality based on both synthetic and empirical data included in the software.

The obtained dielectric spectra can be useful for understanding the relaxation processes in an arbitrary fluid. Solution method: The reflection coefficient data is obtained as a text format from a Vector Network Analyzer (VNA). This text data is parsed into a Numpy array. Three different modules (Stuchly, Marsland, and Komarov) can be used to transform the parsed reflection coefficient data into complex permittivity as a function of the measurement frequency. The resultant dielectric spectra can be dissected and interpreted by fitting either discrete relaxation model(s) based on the Markov Chain Monte Carlo algorithm or a continuous relaxation model by applying the Zasetsky-Buchner method.

The research highlights the highly transient behavior of fast flood flows, particularly when carrying debris, and their effect on bridge superstructures. Utilizing a Digital Elevation Model to extract cross-sectional and elevation data, the research examined 23 profiles over 800 m of the river. The results indicate that the maximum allowable water depth in front of the bridge is 4.73 m, with a Manning's coefficient of 0.03 and a longitudinal slope of 9 m per kilometer. Therefore, a novel method to identify the risks through HEC-RAS modeling significantly improves the conservation of masonry bridges by providing precise topographical and hydrological data for accurate simulations. Moreover, the detailed information obtained from LIDAR and UAV photogrammetry about the bridge's materials and structures can be incorporated into the conservation models. This comprehensive approach ensures that preservation efforts are not only addressing the immediate hydrodynamic threats but are also informed by a thorough understanding of the bridge's structural and material conditions. Understanding rating curves is essential for water management and flood forecasting, with the study confirming a Manning roughness coefficient of 0.03 as suitable for smooth open-channel flows and emphasizing the importance of geomorphological conditions in hydraulic simulation.","2024-08","2025-04-25 15:31:33","2025-04-25 15:31:33","","","","16","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This trend, as well as technological advancements in the unmanned aerial vehicle (UAV) industry, have opened blue skies for both researchers and surveyors. In this study, we aimed to assess the quality of the sparse point cloud obtained with a consumer UAV and a FOSS. To achieve this goal, we also process the same image dataset with a commercial software package using its results as a term of comparison. Various analyses were conducted, such as the image residuals analysis, the statistical analysis of GCPs and CPs errors, the relative accuracy assessment, and the Cloud-to-Cloud distance comparison. A support survey was conducted to measure 16 markers identified on the object. In particular, 12 of these were used as ground control points to scale the 3D model, while the remaining 4 were used as check points to assess the quality of the scaling procedure by examining the residuals. Results indicate that the sparse clouds obtained are comparable. MicMac (R) has mean image residuals equal to 0.770 pixels while for Metashape (R) is 0.735 pixels. In addition, the 3D errors on control points are similar: the mean 3D error for MicMac (R) is equal to 0.037 m with a standard deviation of 0.017 m, whereas for Metashape (R), it is 0.031 m with a standard deviation equal to 0.015 m. The present work represents a preliminary study: a comparison between software packages is something hard to achieve, given the secrecy of the commercial software and the theoretical differences between the approaches.

During their service life, they are subject to deterioration which may reduce their safety and functionality. The detection of bridge damage is necessary for proper maintenance activities. To date, assessing the health status of the bridge and all its elements is carried out by identifying a series of data obtained from visual inspections, which allows the mapping of the deterioration situation of the work and its conservation status. There are, however, situations where visual inspection may be difficult or impossible, especially in critical areas of bridges, such as the ceiling and corners. In this contribution, the authors acquire images using a prototype drone with a low-cost camera mounted upward over the body of the drone. The proposed solution was tested on a bridge in the city of Turin (Italy). The captured data was processed via photogrammetric process using the opensource Micmac solution. Subsequently, a procedure was developed with FOSS tools for the segmentation of the orthophoto of the intrados of the bridge and the automatic classification of some defects found on the analyzed structure. The paper describes the adopted approach showing the effectiveness of the proposed methodology.","2022","2025-04-25 15:31:33","2025-04-25 15:31:33","","298-312","","","1507","","","","Communications in Computer and Information Science","","","","Italian Federat Sci Assoc Territorial & Environm Informat","","","","","","","","","ISSN: 1865-0929","","","","","","BorgognoMondino, E; Zamperlin, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is known that for the unidirectional composites the most significant distortion of the structure of the host material takes place when the optical fiber is embedded perpendicular to the direction of the reinforcement of the composite material layers. However, the internal structure of the composites with woven layer reinforcement scheme is significantly different. And the embedding of such a foreign object as an optical fiber can cause a basically other, as compared to unidirectional composites, change in the internal structure. Cross-sectional studies were performed using an optical microscope. The analysis of cross-sections of PCM samples was carried out with the aim of studying the changes in the structure of the layered composite with woven fabric reinforcement due to the embedding of the fiber-optic sensors. A comparison of the obtained images showed that the microstructure of the studied samples is better seen on polished surfaces. In the absence of polishing on a number of samples, the optical fiber is not visually noticeable or poorly distinguishable. Analysis of the obtained images showed that there is an insignificant distortion of the internal structure of the material in the area with embedded optical fiber without the formation of a resin pocket for all studied GFRP samples. At the same time, when analyzing CFRP samples, the effect of embedding of the optical fiber on the microstructure of the composite was not observed. 2019 The Authors.

The focus of the paper lies in a proof-of-concept for a novel means to develop and execute pervasive services, with simplicity and maintainability as prime drivers. The essence of this approach is the novel integration of the policy-based management (PBM) techniques and the model-driven architecture (MDA) techniques for specifying pervasive services and their behaviour, together with auto-generation of middleware implementation and policy enablement. The presence of policies provides pervasive services with the high flexibility and adaptability needed for dealing with changing environments and resource availabilities, while the introduction of MDA for defining pervasive service information models fundamentally solves the information modelling puzzle of current policy-based approaches. Additionally, MDA's middleware-neutral feature benefits the smooth evolution of pervasive services as a piece of software artefact in the face of heterogeneous devices and platforms. A preliminary case study has demonstrated the practical feasibility and benefits of this approach. The case study revolves around an ICT service called TEANU - transparent enterprise access for nomadic user. The service provides a means for nomadic users to maintain a secure access to their enterprise network in the presence of multiple access network providers with different service level guarantees.","2005-07","2025-04-25 15:31:33","2025-04-25 15:31:33","","162-174","","3","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thus, the Delphi methodology was applied to a panel of experts with two aims: (1) to know managers' perceptions about organizational users' motivations toward OSS after receiving OSS training and (2) to develop a forecasting study to examine the OSS diffusion in the medium term in companies and educational centers. In this context, the Self-Determination Theory (SDT) was the theoretical approach through which we identified the motivational factors. Specifically, three SDT motivations were added: (1) autonomy, (2) competence and (3) relatedness. The 104 selected experts were managers from companies with employees who have studied in educational centers where OSS usage is mandatory. The results show that managers perceive that OSS training incentivizes OSS implementations in companies. At the same time, user motivations are considered to be extremely relevant, especially autonomy.

In order to address this knowledge gap, we proposed a NLP-based approach to predict the programming behaviors in OSS (Open Source Software) communities. The proposed approach i) embeds the historical programming behavior data of a project into a multi-dimensional vector space to capture the potential laws in the data, ii) forms an eigenvector matrix reflecting the semantic relationship of the development behavior data, and predicts the next programming behavior of a specific developer based on the eigenvector matrix. Our experiments on five OSS projects show that the prediction accuracy rate of the proposed prediction approach can reach up to about 50%, indicating that it can summarize the development behavior data law and effectively predict the programming behavior of developers.

These cylinders offer light weight, corrosion resistance, dimensional stability, and the ability to store more air than equivalent metal tanks. The design methodology currently used for composite tanks, however, cannot yet guarantee their safe operation. Accordingly, the U.S. Department of Transportation (DOT) is unable to issue full certification of filament-wound tanks. Rather, some types of composite pressure tanks currently are manufactured under DOT Exemption, TC Regulation 3FCM. The composite tank industry would benefit by improving the safety of operating these tanks. The interest in developing composite pressure tanks is here and the manufacturing technology is mature. What is needed, however, is a means of insuring that composite tanks are as safe to operate as metal tanks. This will facilitate DOT certification and appeal to consumers. This paper discusses a fiber optic sensor system embedded into the composite shell wall as a structural health monitor. Using a simple, low-cost optical fiber sensor and a modified commercial connector, “smart” tanks can be monitored continuously for structural integrity. The opportunity to provide such continuity in structural health monitoring should have a significant positive impact on obtaining DOT certifications and extending product useful life. This paper presents the results of a design program to develop a new filament-wound composite cylinder containing a fiber-optic sensor system (FOSS). The purpose of FOSS is to monitor the structural integrity of the composite material each time the tank is refilled with pressurized gas. Continuous monitoring for material degradation will be an important factor that determines tank recertification intervals and useful tank life. One of the greatest challenges of this design program has been to develop an optical connector that allows external instrumentation to be “plugged into” the composite wall to read optical signals that correlate with structural health. “While embedding fiber sensors has become routine, ingress to and egress from the embedded units remain a major stumbling block” (Spillman, 1995). A simple modification to a commercial connector is proposed for this application. The design and manufacture of the prototype FOSS cylinder shown in Figure 1 are described in this paper. Connector performance and the overall performance of a prototype Type III tank consisting of an aluminum liner, an E-glass/epoxy filament-wound overwrap, and an embedded FOSS are discussed. Results of a pressure test to assess FOSS performance are presented.","2001","2025-04-25 15:31:33","2025-04-25 15:31:33","","191-196","","","","","","","International Offshore and Polar Engineering Conference Proceedings","","","","Int Soc Offshore & Polar Engineers; Canadian Assoc Petr Producers; Amer Soc Civil Engineers, Engn Mech Div; Korea Comm Ocean Resources & Engn; Canadian Soc Civil Engineers, Engn Mech Div; Chinese Soc Ocean Engineers; Chinese Soc Naval Architects & Marine Engineers; Chinese Soc Theoret & Appl Mech; Russian Acad Sci; Singapore Struct Steel Soc; Norwegian Petr Soc; Inst Engineers Australia; Kansai Soc Naval Architects; IRO; Tech Res Ctr Finland; Soc Mat Sci; Offshore Engn Soc; Ukraine Soc Mech Engineers; IFREMER; Scott Polar Res Inst; Inst Engineers Indones; Brazilian Soc Naval Architects & Marine Engineers; Korean Soc Civil Engineers","","","","","","","","","ISSN: 1098-6189","","","","","","Langen, I; Yao, T; Koo, J; Knapp, RH; Chung, JS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In industry, large organizations see dedicated software engineering resources within a networking team. However, in the broader industry, it is more common to see traditional network engineers working on network automation. With the growth of Free and Open Source Software (FOSS), network automation software solutions also started to adhere to this development model. However, as it is known from the literature, onboarding to FOSS projects is not a trivial task and may be more challenging for people without a software development background. In this paper, we study network automation FOSS projects, which are seeing a large number of new contributors who do not have traditional software engineering skills. We analyze a set of data collected from pull requests and issues collected from 81 GitHub projects (71 network automation projects, and 10 top-projects from other domains), to identify the characteristics that are specific to first-time project contributors in the network automation domain. Our results show that pull requests in the Network Automation domain differ from those in the Top-10 set and the existing literature. At the same time that Network Automation projects are more inclusive (rejection rate: 12% vs. 28% on Top-10), the pull request latency is longer in this specific domain, especially for first-timers.","2020","2025-04-25 15:31:33","2025-04-25 15:31:33","","324-335","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 1063-6773","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This analytic distinction presents some limitations in explaining how coordination is reached in organizations characterized by distributed teams, scarce face to face meetings and fuzzy and changing lines of authority, as in free/libre open source software (FLOSS) development. Analyzing empirical illustrations from two FLOSS projects, we highlight the existence of a peculiar model, stigmergic coordination, which includes aspects of both implicit and explicit mechanisms. The work product itself (implicit) and the characteristics under which it is shared (explicit) play an under-appreciated role in helping software developers manage dependencies as they arise. We develop this argument beyond the existing literature by working with an existing coordination framework, considering the role that the codebase itself might play at each step. We also discuss the features and the practices to support stigmergic coordination in distributed teams, as well as recommendations for future research. (C) 2016 The Authors.

Thousands of these projects are collaboratively driven by communities following a shared vision. But governing open communities towards this shared vision comes along with various difficulties. In general, agile methods allow to manage such systems of collaborative development and constant change. But as this work shows, the agile approach not only provides chances in open settings. A variety of challenges occur that need to be considered. The case of Catrobat, a Free/Libre Open Source project, shows that although open source development and agile methods evolved over the last years, the dynamics of open communities still challenge the agile way. However, evaluating and understanding these dynamics, as well as introducing agile elements, such as the role of product owners, can be beneficial for managing open systems and to drive it into a common direction together with the contributors.","2018","2025-04-25 15:31:33","2025-04-25 15:31:33","","1-6","","","","","","","IEEE Conference on Open Systems","","","","IEEE Comp Soc","","","","","","","","","ISSN: 2381-3474","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of Free and Open Source Software (FOSS) projects is one attractive approach for providing students with easy access to a complex, ongoing project of size that is supported by a professional community. Humanitarian FOSS (HFOSS) projects hold the additional appeal to students of developing software that will benefit the human condition. However, student involvement in HFOSS projects can be somewhat unpredictable and less controllable than the development of home-grown projects or projects with an industry partner. Student participation in an HFOSS project means that students are dependent, at least somewhat, on the goals, schedule, and constraints of the HFOSS project itself. Therefore, learning is somewhat reliant on the progress of the HFOSS project. This paper presents results of a multi-year study of student perceptions of learning related to software engineering knowledge and skills while involved in an HFOSS project. The paper includes a background of work in student participation in HFOSS, an outline of the study approach and an explanation of the results.

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways. This may be due primarily to the fact that open source ultimately produces greater value on both the use and production sides, implying an impact on welfare. This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market. To support this, a market concentration index, the HHI index, is tested over the case of web servers. As a result the study reveals that under the appropriate conditions, OSS call have a positive impact on welfare.","2008","2025-04-25 15:31:33","2025-04-25 15:31:33","","1-26","","","","","","","Social Issues Justice and Status","","","","","","","","","","","","","","","","","","","Stroud, BH; Corbin, SE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open source software solutions offer great opportunities for cost reduction and quality improvement, especially for small and medium enterprises that typically have to address major difficulties due to the limited resources available for selecting and adopting a new software system. Objective: This paper aims to provide support for selecting the open source software that is most suitable to the specific needs of an enterprise from among the options offering equivalent or overlapping functionality. Method: This paper proposes a framework for evaluating the quality and functionality of open source software systems. The name of the framework is EFFORT (Evaluation Framework for Free/Open souRce projecTs). It supports the evaluation of product quality, community trustworthiness and product attractiveness. The framework needs to be customised to the analysis of software systems for a specific context. Results: The paper presents the customisation of EFFORT for evaluating Enterprise Resource Planning (ERP) open source software systems. The customised framework was applied to the evaluation and comparison of five ERP open source software systems. The results obtained permitted both the refinement of the measurement framework and the identification of the ERP open source software system that achieved the highest score for each chosen characteristic. Conclusion: EFFORT is a useful tool for evaluating and selecting an open source software system. It may significantly reduce the amount of negotiation conducted among an enterprise's members and reduce the time and cost required for gathering and interpreting data. The EFFORT framework also considers the users' opinions by introducing relevance markers associated with the metrics and questions in the data aggregation process. (C) 2013 Elsevier B.V.

A family of electronic shooting simulators “STrIzh” of four levels of implementation: initial, basic, professional and special is described. Structural diagrams of different configurations are given, functional purpose and capabilities of each level of simulators are shown. The initial level allows independent assemble the simulator from publicly available elements (laptop, webcam, weapon layouts, IR LEDs), which can contribute to widespread use both in schools and at home, but is low in accuracy and manufacturabili (requires daily calibration). The basic level also allows independent assemble the simulator, and less publicly available elements (laptop, projector, mockup weapons, laser emitters, FHD camera), which allows to be used both in schools and in DOSAAF structures, and has acceptable accuracy and manufacturability (a weekly calibration is enough, but assembling a mock-up weapon with laser emitters requires adjustments). It is recommended to limit the special level to virtual reality simulators, including a helmet with a smartphone and a mockup of a weapon with its smartphone which also contributes to its public availability and widespread use. The simulator software algorithm should fully support all implementation levels with different configurations and include a multimedia shooting training system. Mathematical models of external ballistics of thrown equipment for Kalashnikov assault rifle, Makarov pistol, hand-held anti-tank grenade launcher 7 products are described in detail, taking into account changes in atmospheric factors (temperature, air pressure, wind force) and dispersion of various types of ammunition. The above review of rifle simulators and their experience revealed the main trends of improvement - use of virtual reality and training not only direct shooting skills, but also training in the eligibility of the use of weapons, safe handling of them and even tactical interaction in the group.","2023","2025-04-25 15:31:34","2025-04-25 15:31:34","","251-267","","4","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation. We demonstrate how OSS and systematic conservation planning can be taken to the wider community to produce on-the-fly outputs. Our novel approach has the potential to build partnerships with community groups and give the community a sense of ownership in the decision-making process. It is more likely that conflicts will be minimised and negotiation hastened for a better MPA zoning outcome for all.","2005","2025-04-25 15:31:34","2025-04-25 15:31:34","","1525-1531","","","","","","","","","","","","","","","","","","","","","","","","","","Zerger, A; Argent, RM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design and requirements are kept more as informal knowledge, rather than formally described and assessed. This paper attempts to recover the SE concepts of software design and architectures from three FLOSS case studies, sharing the same application domain (i.e., Instant Messaging). Its first objective is to determine whether a common architecture emerges from the three systems, which can be used as shared knowledge for future applications. The second objective is to determine whether these architectures evolve or decay during the evolution of these systems. The results of this study are encouraging: albeit no explicit effort was done by FLOSS developers to define a high-level view of the architecture, a common shared architecture could be distilled for the Instant Messaging application domain. It was also found that, for two of the three systems, the architecture becomes better organised, and the components better specified, as long as the system evolves in time.","2009","2025-04-25 15:31:34","2025-04-25 15:31:34","","34-46","","","299","","","","International Federation for Information Processing","","","","IFIP WG 2 13","","","","","","","","","ISSN: 1571-5736","","","","","","Boldyreff, C; Crowston, K; Lundell, B; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, that is not the only charge that propels contributions-growing interest in open source has also been attributed to software developers deciding to use their technical skills to benefit a common societal good. To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.","2021","2025-04-25 15:31:34","2025-04-25 15:31:34","","1020-1032","","","","","","","International Conference on Software Engineering","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT","","","","","","","","","ISSN: 0270-5257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We propose a method to visualize software's structural differences using call graph. We have applied the method to a product development process and found that our method helps developers to speed up the application of OSS updates and reduce update errors.

Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

Individual object motions typically display a level of dynamic regularity reflecting the existence of an underlying physics or biology. Best results are obtained when this local information is exploited. Additionally, if the particle number is known to be approximately constant, a large number of tracking scenarios may be rejected on the basis that they are not compatible with a known maximum particle velocity. This represents information of a global nature, which should ideally be exploited too. Some time ago, we devised an efficient algorithm that exploited both types of information. The tracking task was reduced to a max-flow min-cost problem instance through a novel graph structure that comprised vertices representing objects from three consecutive image frames. The algorithm is explained here for the first time. A user-friendly implementation is provided, and the specific relaxation mechanism responsible for the method's effectiveness is uncovered. The software is particularly competitive for complex dynamics such as dense antiparallel flows, or in situations where object displacements are considerable. As an application, we characterize a remarkable vortex structure formed by bacteria engaged in interstitial motility.","2013-04","2025-04-25 15:31:34","2025-04-25 15:31:34","","451-460","","2","19","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach re-scales Marchs (1991) framework and applies it to characterize the innovation system of a distributed organization of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two coupled processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from lurking (not contributing or contributing to projects without becoming a member) to laboring (joining one or more projects as members), and to launching (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered developers fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platforms global dynamics.","2008-08","2025-04-25 15:31:35","2025-04-25 15:31:35","","647-710","","4","17","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is also due to the fact that many teachers consume much more resources and also the difficulties faced by teachers and developers in reusing their resources in other environments because they were initially designed for a specific environment.

This is multi-platform software developed in the Java programming language, designed with a remarkably user-friendly graphical interface for the computation of a collection of information-theoretic functions adapted for rank-based unsupervised and supervised feature selection tasks. A total of 20 feature selection parameters are presented, with the unsupervised and supervised frameworks represented by 10 approaches in each case. Several information-theoretic parameters traditionally used as molecular descriptors (MDs) are adapted for use as unsupervised rank-based feature selection methods. On the other hand, a generalization scheme for the previously defined differential Shannon's entropy is discussed, as well as the introduction of Jeffreys information measure for supervised feature selection. Moreover, well-known information-theoretic feature selection parameters, such as information gain, gain ratio, and symmetrical uncertainty are incorporated to the IMMAN software (http://mobiosd-hub.com/imman-soft/), following an equal-interval discretization approach. IMMAN offers data pre-processing functionalities, such as missing values processing, dataset partitioning, and browsing. Moreover, single parameter or ensemble (multi-criteria) ranking options are provided. Consequently, this software is suitable for tasks like dimensionality reduction, feature ranking, as well as comparative diversity analysis of data matrices. Simple examples of applications performed with this program are presented.

The Mill on the Floss is thus a novel whose structure is wholly based on the blending of several types and subgenres. The novel itself depends on the combination of several discourses, which enrich each other and obliquely create the conditions of their compatibility. The very end of the novel thus benefits from the melodramatic dimension and tradition it seems to imitate, whereas the novel itself cannot be termed a melodrama.

The main objectives of this study were: registration of material creep (growth of strain with time at constant external load) and subsequent (after removal of load) recovery of strain using surface mounted and embedded fiber-optic strain sensors.","2019","2025-04-25 15:31:35","2025-04-25 15:31:35","","","","","581","","","","IOP Conference Series-Materials Science and Engineering","","","","Russian Acad Sci, Ural Branch, Inst Continuous Media Mech","","","","","","","","","ISSN: 1757-8981","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The solver surpasses the capabilities of similar open-source projects by considering a wide range of physical effects, e.g. multiple phases, melting, solidification, evaporation, and laser beam heat sources with an arbitrary intensity distribution and thus makes it an appealing framework, especially for the simulation of the laser powder bed fusion (LPBF) process. Herein, all relevant details and derivation considering the Marangoni effect are provided and validated by means of a benchmark problem by comparing the obtained results with the available analytical solution, with the results obtained from a commercial CFD tool and with the results of other authors. The modified solver is additionally validated by comparing the results from LPBF simulations with experimental data. Furthermore, the influence of the surface tension modeling on the mushy region is investigated.

Although multitude of studies have provided effective models for OSS sustainability, their practical implications have been lacking because most identified features are not amenable to direct tuning by developers (e.g., levels of communication, number of commits per project). In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed a comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs). The ReACTs are practical advice with specific steps, found in prior work to associate with tangible results. Starting from a set of sustainability-related features, this study contributes 105 ReACTs to the SE community by analyzing 186 published articles. Moreover, this study introduces a newly developed tool (ReACTive) designed to enhance the exploration of ReACTs through visualization across various facets of the OSS ecosystem.

Once software complexity is one of the most important attributes to determine software maintainability, controlling its level in the system evolution process makes the software easier to maintain, reducing the maintainability costs. Otherwise, uncontrolled complexity makes the maintenance and enhancement process lengthy, more costly and some times it can contribute to the system abandonment.

Their low budget characteristics make the vertical applications these users need natural targets for free/open source software (F/OSS) development efforts. The lack of technological challenges however, does not motivate experienced programmers to specify, code and test verticals. We are thus left with a problem of developing verticals which do not attract ROSS volunteers and whose end-users are not even able to specify them (they are IT naive) nor pay for professional help to do the job for them. This paper proposes a solution to such a problem. The solution is organized in the form of a university level F/OSS vertical development contest, which involves computer science professors as project leaders and students as “volunteered” programmers. Quality of the produced software is guaranteed by means of contest infrastructure, services, support kits which bring vertical seed code, coding and documentation standards and code reviews by the contest steering committee members. One such contest is being carried out in Brazil with the engagement of 5 universities to gain experience and evaluate contest risks, effectiveness and running processes. Results so far are encouraging having produced an already useful city government application. Results also indicated required adjustments in the technical details and procedures but also high levels of professor and student motivation. A nation-wide contest to produce more verticals for small city governments is scheduled to happen next.","2007","2025-04-25 15:31:36","2025-04-25 15:31:36","","197-204","","","4","","","","Information and Communication Technologies and the Knowledge Economy","1-2","","","","","","","","","","","","ISSN: 1574-1230","","","","","","Cunningham, P; Cunningham, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this reason, this work aims to explore some of the effects of participation in a virtual brand community on consumer behaviour. Design/methodology/approach - The paper proposes the positive effects of participation in a virtual community on both consumer trust and loyalty to the product, brand or organisation around which the community is developed. In addition, it also proposes a positive effect of trust on consumer loyalty. After the validations of measurement scales, the hypotheses are contrasted through structural modelling. Findings - The data, obtained through a web survey using members of several free software virtual communities, show that participation in the activities carried out in a virtual community may foster consumer trust and loyalty to the mutual interest of the community (the free software in this case). In addition, the study also found a positive and significant effect of consumer trust on loyalty. Research limitations/implications - Data were collected thanks to a web survey using Spanish-speaking subjects. Practical implications - The high costs every company has to face in order to get new customers make it increasingly necessary to reinforce the ties established with customers. In this respect, this study has shown that managers may foster consumer trust and loyalty by developing virtual brand communities and promoting consumers' participation in them. Originality/value - Most of the works that are focused on virtual communities have been conducted at the conceptual level. Thus, with the aim of moving on this topic, this study analyses empirically the effects of participation in a virtual brand community on consumer behaviour.","2007","2025-04-25 15:31:36","2025-04-25 15:31:36","","775-792","","6","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key success factor is to respond to customers' desires to choose the billing scheme that suits their needs, to subscribe to all services as a service package, and to pay for them via a single bill regardless of service type, service location, service providers and network operators. Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task. This paper presents key OSS functions and an information model that tackle this complexity. Challenges are described and requirements are defined.

For this reason, scanner manufacturers provide researchers with programming frameworks that give full control over the whole procedure. The drawback is that these environments are complex, and the code is non-portable and covered by non-disclosure agreements. In this article, a simplified framework based on a free scripting language (Lua) is presented. It is oriented to the development of postprocessing algorithms that are seamlessly integrated with the pipeline of a commercial scanner. The structure privileges simplicity over performance, to be quickly learned and used by researchers and students who might not be acquainted with low-level programming languages. Common postprocessing algorithms (contrast modulation, pixelwise fitting, phase-contrast imaging) could be implemented with similar to 100 logical lines of code or less, using a syntax that is similar to the Matlab programming language. The average performance of the reconstruction was lower with respect to the native implementation, but superior to offline postprocessing on a desktop computer, without the bottleneck of offline data export.

In revision hip arthroplasty (RHA), establishing the center of rotation (COR) can be technically challenging due to the acetabular bone destruction that is usually present, particularly in severe cases such as Paprosky type II and III defects. The aim of this study was to demonstrate the use of open-source medical image reconstruction software and low-cost 3D anatomical models in pre-surgical planning of RHA. Methods. A total of 10 patients, underwent RHA and were included in the study. Computed tomography (CT) scans were performed for all cases, before surgery and approximately 1 week after the procedure. The reconstruction of CT data, 3D virtual planning of the COR and positioning of acetabular cups, including their inclination and anteversion angles, was carried out using the free open source software platform 3D Slicer. In addition, anatomical models of the pelvis were built on a desktop 3D printer from polylactic acid (PLA). Preoperative and postoperative reconstructed imaging data were compared for each patient, and the position of the acetabular cups as well as the COR were evaluated for each case. Results. Analysis of the pre- and post-op center of rotation position data indicated statistically insignificant differences for the location of the COR on the X-axis (1.5 mm, t = 0.5741, p = 0.5868) with a fairly strong correlation of the results (r = -0.672, p = 0.0982), whilst for the location of the COR in the Y and Z-axes, there was statistical dependence (Y axis, 4.7 mm, t = 3.168 and p = 0.0194; Z axis, 1.9 mm, t = 1.887 and p = 0.1081). A strong correlation for both axes was also observed (Y and Z) (Y-axis, r = 0.9438 and p = 0.0014; Z-axis, r = 0.8829 and p = 0.0084). Analysis of inclination angle values showed a statistically insignificant difference between mean values (3.9 degrees, t = 1.111, p = 0.3092) and a moderate correlation was found between mean values (r = -0.4042, p = 0.3685). Analysis of the anteversion angle showed a statistically insignificant difference between mean values (1.9 degrees, t = 0.8671, p = 0.4192), while a moderate correlation between mean values was found (r = -0.4782, p = 0.2777). Conclusions. Three-dimensional reconstruction software, together with low-cost anatomical models, are very effective tools for pre-surgical planning, which have great potential use in orthopedic surgery, particularly RHA. In up and in- and up and out-type defects, it is essential to establish a new COR and to identify three support points within the revision acetabulum in order to correctly position acetabular cups.","2023-08","2025-04-25 15:31:36","2025-04-25 15:31:36","","","","15","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Methods We measured the PM2.5 (particulate matter with aerodynamic diameter <2.5m) mass concentration in moxa smoke and the oxidative capacity of PM2.5 and moxa ash (using a plasmid scission assay in whole and water-soluble fractions) in the by-products of moxibustion produced from burning moxa floss of different ratios (3:1 or 15:1) and duration of storage (3 or 10years) in three simulated moxibustion clinics. Results PM2.5 mass concentration was 224.28, 226.39 and 210.56g/m(3) for samples A (3years and 3:1 ratio), B (3years and 15:1 ratio), and C (10years and 3:1 ratio), respectively. Average D-500 oxidative damage of PM2.5 was 29.42%, 29.16% and 27.01% and that of moxa ash was 22.78%, 20.60% and 21.42% for samples A, B and C, respectively. PM2.5 demonstrated a significantly greater oxidative capacity than moxa ash (p<0.05). Conclusions The oxidative DNA damage induced by individual PM2.5 following moxibustion was lower than that reported in other environments. However, PM2.5 mass concentration after moxibustion is still relatively high. We would recommend ensuring adequate ventilation during moxibustion to reduce any possible risks. Further studies are needed to better define the potential impact of particles in moxibustion by-products on human health.","2016-04","2025-04-25 15:31:37","2025-04-25 15:31:37","","101-106","","2","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The field study produced a bleak result: software professionals found gender biases in 73 percent of all the newcomer barriers they identified. Further, the diary study confirmed these results: Women newcomers encountered gender biases in 63 percent of barriers they faced.

In this paper, we investigate that facet of software using a configurable simulation framework as a basis. The framework uses `agents' to represent developers and models the costs associated with first comprehending and then applying necessary changes to a fictitious code base. It also considers agent `memory recall' of their own code as a fundamental part of the framework and the fact that, with higher numbers of developers, maintenance of a higher proportion of other developers' code (rather than their own) is an inevitable, yet realistic aspect. Through exploration of the results and data produced by the simulation. We are able to explore `desirable' features that are part of simulating software evolution; as a discussion of the issues raised by the framework, we provide a set of class data from four open-source systems by way of comparison and show that trends in those systems are comparable with results generated by the simulation. The paper thus provides evidence that we can use simulation tools to help model evolving systems, whether based on default settings or user-configurable settings.","2009","2025-04-25 15:31:37","2025-04-25 15:31:37","","13+","","","","","","","Australian Software Engineering Conference","","","","Australian Comp Soc; Engineers Australia; asCSA; Bond Univ; Davies Collison Cave; E-HEALTH; Griffith Univ; Hearne; K J Ross & Assoc; Fac Sci & Technol; SUNCORP; SWiNBURNE; Thought Works; Univ Queensland; Invensys Westinghouse","","","","","","","","","ISSN: 1530-0803","","","","","","Fidge, C","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Clinical use with prostate gold fiducial markers is presented. Methods Projections of regions of interest (ROI) in the reference frame of the electronic portal imaging device are computed offline for different gantry angles before the first treatment fraction. During treatment delivery, the contrast of portal images is automatically adjusted using a histogram equalization algorithm. The projections associated with the current gantry angle are then superimposed on the images in real time. This allows the therapist to evaluate if the imaged structures of interest remain within their respective contours during treatment delivery and to potentially interrupt the treatment if deemed necessary. The spatial accuracy of the method was evaluated by imaging a ball bearing phantom in a set-up where the position of the projected ROI is highly sensitive to gantry angle errors. The visibility of fiducial markers during one fraction of seven different volumetric modulated arc therapy (VMAT) prostate treatments is characterized. Results The geometric validation showed a negligible systematic error mu < 0.1 mm for the position of the projections. The random errors associated with the time accuracy of the gantry angle readout were characterized by standard deviations sigma <= 0.6 mm. The VMAT clinical treatments showed that the fiducial markers were frequently visible, allowing for a meaningful clinical use. Conclusions The results demonstrate that the method presented is sufficiently accurate to be used for intrafraction monitoring of patients. The fact that this method could be implemented on many modern linacs at little to no cost and with no additional dose delivered to the patients makes this solution very attractive for improving patient care and safety in radiation therapy.","2020-08","2025-04-25 15:31:37","2025-04-25 15:31:37","","173-182","","8","21","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although industrial applications traditionally rely on PLC-based hardware and, in any case, proprietary software, i.e. operating systems and development tools, in recent years dramatic improvements in hardware computer power and free software quality made realistic the employment of architectures based on PC-compatible hardware and GNU/Linux software, more common in the research community. The advantages of a free infrastructure, that can become the terrain of fruitful cooperation between research institutions and companies, can be exploited mainly in fields, in which the added value is in the application, i.e. in mechanical and algorithmic solutions, and where the point of view is that of aware users of an infrastructure, rather than of R&D competitors. This is the case of the project presented in the following, representing a success story in which the discussion between a research group and a small enterprise led to the identification of the requirements and the joined development of a common software infrastructure. When the project started in 2004, both partners, i.e. the Autonomous robotic systems and control group of CNR-ISSIA and Green Project Srl, had to substitute the obsolete platforms of their marine robots and marking machines for casting products in steelworks with a stable software and hardware infrastructure able of transparently integrating technological improvements while remaining compatible with the past (backward compatibility). On the basis of considerations, discussed below, about system reliability, development and maintenance costs (including human resources), foreseen compatibility and general technical soundness, the choice was to verify the possibility of using standard GNU/Linux for embedded real-time applications. The result is the main technical contribution of this chapter, i.e. the practical demonstration of the possibility of using standard GNU/Linux for implementing embedded real-time control systems working up to a sampling frequency of at most 2 Khz. Furthermore, four years later, the developed system is still demonstrating its capabilities transparently integrating technological improvements and increasing more and more its performance thanks to the new real-time properties of the Linux kernel. A first operative release of the platform was completed in 2005 and integrated with the CNR-ISSIA Charlie unmanned surface vehicle (USV) for robotics research. A second application was the porting to the platform of the software of the control system of Hammer, a steelwork industrial machine used for marking continuous casting products, developed by Greenproject s.r.l. At the moment, the platform is supporting the development of the ALANIS (Aluminium Autonomous Navigator for Intelligent Sampling) USV1 for surface and underwater coastal monitoring. Moreover, the integration with generic field buses and image acquisition systems is being carried out. After an introduction reporting a summary of related research in the field and a discussion of the platform requirements, the key points of the followed methodology for making GNU/Linux real-time will be presented. Finally, two applications, a research one and an industrial one, pointing out the basic real-time structures that the platform is required to implement, will be described.","2010","2025-04-25 15:31:37","2025-04-25 15:36:52","","211-225","","","","","","","Computer Science Technology and Applications","","","","","","","","","","","","","","","","","","","Hayes, M; Johansen, I","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Goal. The goal of the investigation documented in this paper is to obtain a clear picture about the introduction of Open Source Software technologies in the Public Administration, the obstacles to their adoption, and the willingness of stakeholders to proceed with their introduction. Method. We carried out a qualitative and quantitative survey that was submitted to a representative part of the Public Administrations in Lombardy. Results. The analysis of the qualitative and quantitative information shows that several Public Administrations are already using Open Source Software technologies, though not in all application areas. The savings are one frequently cited incentive to the adoption of Open Source Software. However, one obstacle is the fact that a comprehensive law on software in the Public Administration has not yet been approved. Conclusions. Our analysis provides results that indicate a common understanding of incentives, obstacles, and opportunities for Open Source Software technologies in Public Administrations.","2015","2025-04-25 15:31:37","2025-04-25 15:31:37","","114-123","","","451","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 2 13; Google","","","","","","","","","ISSN: 1868-4238","","","","","","Damiani, E; Frati, F; Riehle, D; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It has been reported that less than 10% of Open Source Software (OSS) contributors in GitHub are women. Although related qualitative and quantitative studies point out the gender gap, the technical and social interaction of females within OSS still remain unexplored and largely misunderstood. As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions. Thus, we propose to answer the questions: where are females in OSS projects? How they evolve? and How they contribute to the sustainability of the OSS social capital?. We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity. We found that females are extremely underrepresented within OSS communities, but when they participate they are productive just as males, they evolve following relatively the same patterns than males and remain more involved in projects than males.","2019","2025-04-25 15:31:37","2025-04-25 15:31:37","","308-319","","","","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 5 5 COVE Co Operat infrastructure Virtual Enterprises & Elect Business; Soc Collaborat Networks; Politecnico Torino; Nova Univ Lisbon; UNINOVA; Univ Amsterdam","","","","","","","","","ISSN: 1868-4238","","","","","","CamarinhaMatos, LM; Afsarmanesh, H; Antonelli, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Two feature that makes them particularly attractive are their interactive nature and easy testing during the model development process. However, they are less suited for operation as production level models due to their slow simulation performance. This paper presents a new extension to the EDD that offers C++ model performance coupled with the convenience of EDD modelling. The extended form of the EDD is called a Verilog-A EDD or VAEDD for short. It has the same structure as the standard EDD but is built around compiled Verilog-A module code, which in turn is translated to C++ code and dynamically linked to the main body of the simulator code. Essentially a VAEDD is a tiny Verilog-A module with a standardised internal code structure. To demonstrate the interactive approach to compact model building with VAEDD components the design and testing of a high power SiC Schottky barrier diode is included in the main body of the text.","2019","2025-04-25 15:31:37","2025-04-25 15:31:37","","92-97","","","","","","","","","","","IEEE; Lodz Univ Technol, Dept Microelectron & Comp Sci; Warsaw Univ Technol, Inst Microelectron & Optoelectron; Poland Sect IEEE ED & CAS Chapters; Polish Acad Sci, Comm Elect & Telecommunicat, Sect Microelectron & Electron Technol; Polish Acad Sci, Comm Elect & Telecommunicat, Sect Signals, Elect Circuits & Syst; Int Union Radio Sci, Polish Natl Comm, Commiss Elect & Photon","","","","","","","","","","","","","","","Napieralski, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These platforms are usually centered in a specific brand/product and their members are linked by a shared admiration to that brand. This paper analyzes one of the most powerful online collaborative platforms, the free software (FS) case, which involves a lot of virtual communities developed around products such as Linux or Android, the new Google's mobile operating system. Our purpose is to determine some of the main antecedents and consequences of the consumer involvement in this type of communities. Results have shown that satisfaction with a virtual community may increase the level of consumer participation in that community. At the same time, a greater identification with the virtual community may increase indirectly the consumer participation thanks to the enhancement of his/her satisfaction with the community. We have also found positive and significant effects of consumer identification and participation on the level of community promotion. Finally, positive and significant effects of consumer participation and satisfaction with the community on loyalty to the FS were also found. These findings allow us to conclude some interesting managerial implications. (C) 2010 Elsevier Ltd.

To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters were identified: Sporadic Sharer; Collector; Donator; and Constant Sharer. With the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators and Collectors. These results confirm the view of free software communities as communities of practice and highlight the importance of knowledge sharing in free software development cycle. The results reveal the importance of the Constant Sharer profile, which has the highest rates of donation and collection and is also the profile in which all the motivations appear with the highest values, indicating its key role in the functioning of free software communities.","2018-09","2025-04-25 15:31:37","2025-04-25 15:31:37","","143-152","","3","25","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Investigating the inactivity of OSS core developers in GitHub","EMPIRICAL SOFTWARE ENGINEERING","","1382-3256","10.1007/s10664-021-10012-6","","Several Open-Source Software (OSS) projects depend on the continuity of their development communities to remain sustainable. Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94% of the surveyed core developers agreed with our state model of inactivity; 71% and 79% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26%, with a similar to 54% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.","2022-05","2025-04-25 15:31:38","2025-04-25 15:31:38","","","","3","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the use of these tools for education purposes faces important barriers: the availability of the resources, the cost and the students' perception, among many others. These problems might be overcome by the use of free software simulators. In this paper, we present several experiences using free software tools in engineering Higher Education courses. The experiences shown cover several courses of different engineering Degrees: “Electronics and Automation”, “Electrical Engineering”, “Computing” and “Industrial Technologies”. These tools have been used in teaching activities for several years. As a result, the perceptions, gained experience and views of the teachers involved in the different courses are presented and discussed. Teachers specially valued the independence of the tools from commercial policies, as well as the suppression of expensive licenses. Additionally, they perceived that students understood better the simulations performed since all the parts of the tools could be freely accessed. They also remarked the possibility of changing the code at low level and fuse different free software projects together, what is not possible with the commercial tools. In addition, free software resources allowed students to start in a very common world currently, the collaborative communities, which may be of great importance in their future professional activities. However, teachers involved in these experiences also detected several drawbacks. In some cases, free software simulators are less robust than their commercial alternatives, which usually pay special attention at the design, being perceived by students as a signal of higher quality. In some simulators the documentation is incomplete, and there is a lack of easy-to-use examples which hinders the use of the tool by low-experienced users such as first-year students. The opportunities and threats faced by these tools are also discussed, concluding that when selecting an educational resource, the free software resources must be considered as perfectly valid options in the same conditions as the proprietary solutions.","2016","2025-04-25 15:31:38","2025-04-25 15:31:38","","8653-8662","","","","","","","EDULEARN Proceedings","","","","","","","","","","","","","ISSN: 2340-1117","","","","","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

What can we do to incentivize developers to write code? We started the study by introducing the population pyramid visualization to software development communities, called software population pyramids, and found a typical pattern in shapes. This pattern comes from the differences in attracting coding contributors and discussion contributors. To understand the causes of the differences, we then build game-theoretical models of the contribution situation. Based on these results, we again analyzed the projects empirically to support the outcome of the models, and found empirical evidence. The answers to the initial questions are clear. To incentivize developers to code, the projects should prepare documents, or the projects or third parties should hire developers, and these are what sustainable projects in GitHub did in reality. In addition, making innovations to reduce the writing costs can also have an impact in attracting coding contributors.","2015","2025-04-25 15:31:38","2025-04-25 15:31:38","","15-21","","","","","","","","","","","IEEE COMP SOC; TCSE; ACM; SIGSOFT","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As a society advancing towards the democratization of information and collaborative processes, the researchers should not only focus on improving the efficacy of filters, but should also consider the users' needs with a view toward improving the usability and accessibility of the filters in order to develop tools that will provide solutions to the challenges facing this field of study. In this work, we describe the Hybrid Overlap Filter (HyOF), a new filtering algorithm implemented in the free R software environment. The flow diagram of HyOF differs in the following ways from that of other filters developed to date: (1) the algorithm is formed by a combination of sequentially operating functions (i.e., the output of the first function provides the input of the second), which are capable of functioning independently and thus enabling integration of these functions with other filtering algorithms; (2) the variable penetrability is defined and used, along with slope and elevation, to identify ground points; (3) prior to selection of the seed points, the original point cloud is processed with the aim of removing points corresponding to buildings; and (4) a new method based on a moving window, with longitudinal overlap between windows and transverse overlap between passes, is used to select the seed points. Our hybrid filtering method is tested using 15 reference samples acquired by the International Society of Photogrammetry and Remote Sensing (ISPRS) and is evaluated in comparison with 33 existing filtering algorithms. The results show that our hybrid filtering method produces an average total error of 3.34% and an average Kappa coefficient of 92.62%. The proposed algorithm is one of the most accurate filters that has been tested with the ISPRS reference samples.","2020-04","2025-04-25 15:31:38","2025-04-25 15:31:38","","","","7","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In fact, geographic information has unique intrinsic features, which makes it a natural indexing mechanism for spatial data. Due to its high cost and upgrade dynamics, this information should be available for reuse and should be managed and maintained by those responsible for producing it as part of management interventions in the territory. Therefore, it is important that different spatial data infrastructures, developed at different hierarchical levels, coexist and communicate in an interoperable way so that they can constitute a spatial basis of reference that facilitates the integration with other sectorial applications. This ongoing work proposes the implementation of a regional spatial data infrastructure based on free software, in compliance with the principles of the EU INSPIRE Directive and with the OGC standards.","2012","2025-04-25 15:31:38","2025-04-25 15:31:38","","","","","","","","","Iberian Conference on Information Systems and Technologies","","","","Univ Politecnica Madrid (UPM), Asociacion Iberica Sistemas & Tecnologias Informacion (AISTI)","","","","","","","","","ISSN: 2166-0727","","","","","","Rocha, A; CalvoManzano, JA; Reis, LP; Cota, MP","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this ecological problem, the strict restriction and requirement limit the development of management about algae bloom. To select the most suitable strategy from various algae control methods, we propose case-based reasoning-optimal strategy selection (CBR-OSS) model. It builds case library and complex network by extracting the factors of algae management. This model regards the complex network as a directive network to reflect dynamic characteristic and weights of key factors. To improve decision efficiency, it defines the restriction slots and condition slots in directive network. As the inference engine, these slots exclude the unsuitable cases and avoid the redundancy computation so that the model can calculate the similarity between the target water body and screen cases in the process of decision case matcher. This process finds the best matching case and recommended measures by intuitionistic fuzzy rough sets. To verify the model, Kunming Lake and other 20 lakes are simulated with the proposed method. The results accord with expert advice and the model outperforms in accuracy, operation time, expert participation and flexibility.","2019-11","2025-04-25 15:31:38","2025-04-25 15:31:38","","1-12","","","167","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Motivated by this potential, we model the partner recommendation as link prediction task from email data via network embedding methods. In this article, we introduce time-series snapshot network (TSSN) that is a mixture network to model the interactions among users and developers. Based on the established TSSN, we perform temporal biased walk (TBW) to automatically capture both temporal and structural information of the email network, i.e., the behavioral similarity between individuals in the OSS email network. Experiments on ten Apache data sets demonstrate that the proposed TBW significantly outperforms a number of advanced random walk-based embedding methods, leading to the state-of-the-art recommendation performance.","2022-08","2025-04-25 15:31:38","2025-04-25 15:31:38","","1048-1059","","4","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To explore and understand problems and challenges of current system requirement-OSS component matching and mismatches resolution practices in software development projects that integrate one or more OSS components into their software products. Semi-structured in-depth interviews with 25 respondents that have performed RE activities in software development projects that integrate OSS components in 25 different software development companies in Spain, Norway, Sweden, and Denmark. The study uncovers 15 observations regarding system requirements-OSS components matching and mismatch resolution practices used in industrial projects that integrate OSS components. The assessed projects focused mainly on pre-release stages of software applications that integrate OSS components in an opportunistic way. The results also provide details of a set of previously unexplored scenarios when solving system requirement-OSS component mismatches; and clarify some challenges and related problems. For instance, although licensing issues and the potential changes in OSS components by their corresponding communities and/or changes in system requirements have been greatly discussed in the RE literature as problems for OSS component integration, they did not appear to be relevant in our assessed projects. Instead, practitioners highlighted the problem of getting suitable OSS component documentation/information.","2018-12","2025-04-25 15:31:39","2025-04-25 15:31:39","","3073-3128","","6","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In such areas, ranging from environmental monitoring to precision agriculture, the ortophotos are the most commonly requested digital photogrammetric product. In fact, by using a GIS platform, the ortophotos can enable the integration of radiometric and spectral image data with the geographic and cartographic data and allow us to expand the spatial analysis to other types of attribute data. In this paper we present a methodology for the automatic production of ortophotos in urban areas by using UAVs and open source photogrammetric software. The potential and limits of this technology are assessed in the context of updating a municipal spatial database. The results show that the synergistic use of UAVs and open source photogrammetric software can be effectively used to produce ortophototos of small urban areas with an excellent quality/price ratio.","2015","2025-04-25 15:31:39","2025-04-25 15:31:39","","705-722","","","","","","","Documentos","","","","Univ Coimbra, Fac Master Geog Informat Technologies; Vasco Gama Pastelarias; Municipia; PRAXIS; Porto Editora; Escola Profiss Profitecla; Delta Cafes; Unicer; Faunalia; DIGITalGEO; APEDI; MundoGEO; Inst Geo Direito; gvSIG Asociac; Distico; Turismo Centro Portugal; iNSEC; FCT; Centro Estudos Geografia Ordenamento Territorio; DMat; DEI; Direcao Geral Territorio; Inst Geografico Excercilo; Ordem Engn, Regiao Centro","","","","","","","","","","","","","","","DosSantos, JG; Fonte, C; DeFigueiredo, RF; Cardoso, A; Goncalves, G; Almeida, JP; Baptista, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various projects are in hand by different organizations to explore and implement the Mobile Adhoc Networking (MANET) feature on Android based devices due to their peculiar infrastructure-less requirements (such as disaster management, nomadic battle fields having no communication infrastructure, search and rescue operations etc). These projects carrying out research on MANETs have successfully implemented adhoc networking on few targeted devices, hence implementation of Mobile Adhoc Network (MANET) on every new Android based device is quite challenging in nature. We have researched on Commercial Off the Shelf (COTS) devices (such mobile phones and tablets) to implement adhoc networking using open source software (OSS) such as Serval Mesh, MANET Manager, WiFi Tether applications. We have also modified the TrevE-Mod WiFi Tether application to work successfully with MANET Manager and Linux/ Windows based Personal Computers (PCs) in an adhoc network. The results achieved by performance evaluation tools and testing of VoIP applications have proved it to be satisfactory. We have also satisfactorily implemented, configured and tested point to point Virtual Private Network (VPN) between MANET nodes using OSS (VPN Server, OpenVPN for Android, OpenVPN Connect). The application of standards based security algorithms (for authentication and encryption in VPNs) demonstrates that these technologies can be effectively used for secure collaboration in adhoc environments as well.","2016","2025-04-25 15:31:39","2025-04-25 15:31:39","","485-492","","","","","","","","","","","Honeywell Int Inc; Knowledge Based Syst Inc; Ball Aerosp & Technologies Corp; Intel Corp; Microsoft Res; Springer Verlag","","","","","","","","","","","","","","","Smari, WW","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nowadays, pork floss is known to consumers as a leisure food. It is made from pork through a unique process in which the muscle fibers become flaky or granular and tangled. In this study, a deep learning-based approach is proposed to detect the quality characteristics of pork floss structure. Describe that the experiments were conducted using widely recognized brands of pork floss available in the grocery market, omitting the use of abbreviations. A total of 8000 images of eight commercially available pork flosses were collected and processed using sharpening, image gray coloring, real-time shading correction, and binarization. After the machine learning model learned the features of the pork floss, the images were labeled using a manual mask. The coupling of residual enhancement mask and region-based convolutional neural network (CRE-MRCNN) based deep learning framework was used to segment the images. The results showed that CRE-MRCNN could be used to identify the knot features and pore features of different brands of pork floss to evaluate their quality. The combined results of the models based on the sensory tests and machine vision showed that the pork floss from TC was the best, followed by YJJ, DD and HQ. This also shows the potential of machine vision to help people recognize the quality characteristics of pork floss structure.","2023","2025-04-25 15:31:39","2025-04-25 15:31:39","","","","","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As such access to PHC services is an important factor to ensure good health of a community. While the need to provide equal and easy access to PHC is well understood, the approaches informing the decision-making process to improve the access tend to face a number of challenges in the developing world. Use of conventional Information and Communication Technologies (ICTs) comes with requisite financial costs which Free and Open Source Software (FOSS) ICT technologies have the potential to help lower among other benefits. In this study, the confluence of spatial accessibility tools provided by FOSS technologies, specifically PostgreSQL/PostGIS and QGIS, was explored to inform decision making in PHC accessibility in Zomba, Malawi. The results show that the household population (P) that is within the threshold time was 8, representing % of all households having access to health care. The mean accessibility score for the district was 0.010 and ranged from 0.00 to 0.231. While the findings provide, arguably, spatially objective PHC accessibility data to inform policy direction and also reveals accessibility to PHC in Malawi to be lower than reported, the study also reveals the usefulness of FOSS technologies, in the developing world. Use of FOSS facilitated incremental setup of the model thereby allowing to run the model with limited processing power. That notwithstanding, the study adds to the formal scientific research on the use of relational spatial analysis in the developing world.","2019","2025-04-25 15:31:39","2025-04-25 15:31:39","","189-195","","","42-4","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences","","","","ISPRS","","","","","","","","","ISSN: 1682-1750 Issue: W14","","","","","","Brovelli, MA; Marin, AF","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The challenge facing most organizations is how to evaluate OSS adoption benefits. OSS adoption is a complex phenomenon which requires an interdisciplinary approach to understand the socio-technical, political, economic and legal benefits. The complexity of the OSS phenomenon has resulted in fiercely contested, contradictory rhetorical discussions among divided parties with no conclusive general agreement. The one size fits all approach is fundamentally flawed for evaluating OSS benefits in organizations as they are both subjective and contextual. In this paper we propose a framework to balance the needs of hard (objective) benefits and soft (subjective) benefits of OSS adoption in public sector organizations. This paper proposes a framework to evaluate benefits of OSS adoption in public-sector organizations, since one-size-fits-all approaches have shortcomings to complex phenomena.","2013","2025-04-25 15:31:39","2025-04-25 15:31:39","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A further, cross-cutting characterization of developers could be achieved by associating developers with “time slots”, and different patterns of activity and effort could be associated to such slots. Such analysis, if replicated, could be used not only to compare different FLOSS communities, and to evaluate their stability and maturity, but also to determine within projects, how the effort is distributed in a given period, and to estimate future needs with respect to key points in the software life-cycle (e.g., major releases). This study analyses the activity patterns within the Linux kernel project, at first focusing on the overall distribution of effort and activity within weeks and days; then, dividing each day into three 8-hour time slots, and focusing on effort and activity around major releases. Such analyses have the objective of evaluating effort, productivity and types of activity globally and around major releases. They enable a comparison of these releases and patterns of effort and activities with traditional software products and processes, and in turn, the identification of company-driven projects (i.e., working mainly during office hours) among FLOSS endeavors. The results of this research show that, overall, the effort within the Linux kernel community is constant (albeit at different levels) throughout the week, signalling the need of updated estimation models, different from those used in traditional 9am-5pm, Monday to Friday commercial companies. It also becomes evident that the activity before a release is vastly different from after a release, and that the changes show an increase in code complexity in specific time slots (notably in the late night hours), which will later require additional maintenance efforts.","2013-02","2025-04-25 15:31:39","2025-04-25 15:31:39","","60-88","","1","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article, the bug closure process that is followed by a community of an open source software project is investigated in order to perform process conformance checking. Actual data that reveal the process steps have been extracted from the project's Bugzilla database and have been used as input in Disco process mining tool. The data includes extracted information for more than 19,000 bugs for the past 15 years in a csv form, formatted appropriately to construct an event log suitable for process mining. The extracted models have been compared to the process described in the project's blogs and wikis by the community. The same models are also compared to the bug closure process that Bugzilla suggests to be used by the projects using this software for bug tracking purposes. The findings reveal that indeed the process followed in the OSS project is very similar to the declared one but variations do occur under specific circumstances. However, the process is not identical to the one proposed by Bugzilla suggesting that each OSS project can customize its processes in order to better address the needs of the project and the community.

A methodology to integrate GIS and statistics in morphometric analysis is presented for the most usual morphometric parameters-hypsometry, slope, aspect, swath profiles, lineaments and drainage density, surface roughness, isobase and hydraulic gradient. The GIS used was the Geographic Resources Analysis Support System (GRASS-GIS), an open-source project that offers an integrated environment for raster and vector analysis, image processing and maps/graphics creation. Statistical analysis of parameters can be carried out on R, a system for statistical computation and graphics, through an interface with GRASS that allows raster maps and points files to be treated as variables for analysis. The basic element for deriving morphometric maps is the digital elevation model (DEM). It can be interpolated from scattered points or contours, either in raster or vector format; it is also possible to use DEMs from NASA's Shuttle Radar Topographic Mission, with 30 m of ground resolution for the USA and 90 m for other countries. Proposed methodology can be adapted according to necessities and available tools.

Currently, FAQ chatbot is the most popular domain of use of dialog assistants. However, developing a chatbot project requires a full-stack team formed by numerous specialists, such as dialog designer, data scientist, software engineer, DevOps, business strategist and experts from the domain, which can be both time and resources consuming. Language processing can be particularly challenging in languages other than English due to the scarcity of training datasets. Most of the requirements of FAQ chatbots are similar, domain-specific, and projects could profit from Open Source Software (OSS) reuse. In this paper, we examine how OSS FAQ chatbot projects can benefit from reuse at the project level (black-box reuse). We present an experience report of a FLOSS FAQ chatbot project developed in Portuguese to an e-government service in Brazil. It comprises of the chatbot distribution service, as well as for analytics tool integrated and deployed on-premises. We identified assets that could be reused as a black-box and the assets that should be customized for a particular application. We categorized these assets in architecture, corpus, dialog flows, machine learning models, and documentation. This paper discusses how automation, pre-configuration, and templates can aid newcomers to develop chatbots in Portuguese without the need for specialized skills required from tools in chatbot architecture. Our main contribution is to highlight the issues non-English FAQ chatbots projects will likely face and the assets that can be reused. It allows non-chatbot experts to develop a quality-assured OSS FAQ chatbot in a shorter project cycle.","2019","2025-04-25 15:31:39","2025-04-25 15:31:39","","","","","","","","","","","","","Univ Skovde; Swedish Competit Author; ACM Special Interest Grp Software Engn; ACM SIGWEB; ACM In Cooperat","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach could provide developing countries with many benefits like: saving in cost of development, higher quality, providing opportunity for knowledge and technology transfer etc. In spite of this potential benefits, statistics about success of OSS projects in developing countries is not promising. This paper investigates the main challenges and difficulties which we recognized as the major obstacles in OSS development in developing countries.

When collaborating with other firms whose sought values are conflicts of interests, firms may behave uncooperatively leading to harmful impacts on the common goal. Aim: This study explores how software firms both collaborate and compete in OSS projects. Method: We adopted a mixed research method on three OSS projects. Result: We found that commercial firms participating in community-initiated OSS projects collaborate in various ways across the organizational boundaries. While most of firms contribute little, a small number of firms that are very active and account for large proportions of contributions. We proposed a conceptual model to explain for coopetition among software firms in OSS projects. The model shows two aspects of coopetition can be managed at the same time based on firm gatekeepers. Conclusion: Firms need to operationalize their coopetition strategies to maximize value gained from participating in OSS projects.","2019","2025-04-25 15:31:40","2025-04-25 15:31:40","","37-62","","1","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The evaluation and comparison of more than one examination is time-consuming and prone to create errors. Using the free software environment R we developed a solution to average the data of multiple examinations and to allow a comparison of different patient groups. Methods: Data of single mfERG recordings as exported in .csv format from a RETIport 21 system (version 7/03, Roland Consult) or manually compiled .csv files are the basis for the calculations. The R software extracts response densities and implicit times of N1 and P1 for the sum response, each ring eccentricity, and each single hexagon. Averages can be calculated for as many subjects as needed. The mentioned parameters can then be compared to another group of patients or healthy subjects. Application of the software is illustrated by comparing 11 patients with chloroquine maculopathy to a control group of 7 healthy subjects. Results: The software scripts display response density and implicit time 3D plots of each examination as well as of the group averages. Differences of the group averages are presented as 3D and grayscale 2D plots. Both groups are compared using the t-test with Bonferroni correction. The group comparison is furthermore illustrated by the average waveforms and by boxplots of each eccentricity. Conclusions: This software solution on the basis of the programming language R facilitates the clinical and scientific use of the mfERG and aids in interpretation and analysis.","2018-01","2025-04-25 15:31:40","2025-04-25 15:31:40","","87-93","","1","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Consequently, network management as we have known it up to now, with its silos and rigid approach, cannot meet these expectations. If we add the Internet of Things, the network has to become dynamic, adaptable and flexible. In this context, the industry and forums have specified and standardized a new architecture based on Software Defined Network (SDN), Network Function Virtualization, and Orchestration. These new paradigms, and especially Orchestration, will have a great impact on the Legacy Network Management Systems and the Operations Support System (OSS). We present a state of the art review of the main architecture approaches in the SDN standardization forums and discuss the place of the Orchestration in these different architectures. Then we focus on the Orchestration at the application layer and show how, together with SDN and Network Function Virtualization, they influence the Operation and Business Support Systems of next-generation network management. Finally, we analyze the roles and functions of this Orchestrator with regard to upper management, as well as the several open challenges in this domain.","2019-02","2025-04-25 15:31:40","2025-04-25 15:31:40","","17-31","","","62","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using social capital theory in a mixed methods case study, we compare entrepreneur and non-entrepreneur behaviors to investigate how entrepreneurs build social capital within an OSS community. This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation). Given the liabilities of newness and smallness as well as other challenges faced by entrepreneurs, applying an open innovation strategy in OSS communities could be one approach where entrepreneurs, by developing and freely revealing their intellectual property to the community, share their way to success via OSS-infused entrepreneurial business ventures.","2019-03","2025-04-25 15:31:40","2025-04-25 15:31:40","","23-40","","1","29","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper studies (i) types of modifications that may affect vulnerable open-source dependencies and (ii) their impact on the performance of vulnerability scanners. Through an empirical study on 7,024 Java projects developed at SAP, we identified four types of modifications: re-compilation, re-bundling, metadata-removal and re-packaging. In particular, we found that more than 87 percent (56 percent, resp.) of the vulnerable Java classes considered occur in Maven Central in re-bundled (re-packaged, resp.) form. We assessed the impact of these modifications on the performance of the open-source vulnerability scanners OWASP Dependency-Check (OWASP) and Eclipse Steady, GitHub Security Alerts, and three commercial scanners. The results show that none of the scanners is able to handle all the types of modifications identified.

The OSS technique allows for the rapid calculation of radiance for any class of multispectral, hyperspectral, or ultraspectral sensors at any spectral resolution operating in any region from microwave through UV wavelengths by selecting and appropriately weighting the monochromatic points that contribute over the sensor bandwidth. This allows for the calculation to be performed at a small number of spectral points while retaining the advantages of a monochromatic calculation such as exact treatment of multiple scattering and/or polarization. The OSS method is well suited for remote sensing applications which require extremely fast and accurate radiative transfer calculations: atmospheric compensation, spectral and spatial feature extraction, multi-sensor data fusion, sub-pixel spectral analysis, qualitative and quantitative spectral analysis, sensor design and data assimilation. The OSS was recently awarded a U.S. Patent (#6,584,405) and is currently used as part of the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) CrIS, CMIS, and OMPS-IR environmental parameter retrieval algorithms. This paper describes the theoretical basis and development of OSS and shows examples of the application and validation of this technique for a variety of different sensor types and applications.","2004","2025-04-25 15:31:40","2025-04-25 15:31:40","","368-374","","","5425","","","","PROCEEDINGS OF THE SOCIETY OF PHOTO-OPTICAL INSTRUMENTATION ENGINEERS (SPIE)","","","","SPIE","","","","","","","","","ISSN: 0277-786X","","","","","","Shen, SS; Lewis, PE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The social and technical activities of developers evolve together, and as they link to each other they get organized in a network of changing socio-technical connections. Traces of those activities, or behaviors, are typically visible to all, in project repositories and through communication between them. Thus, in principle it may be possible to study those traces to tell which of the observable socio-technical behaviors of developers in these projects are responsible for the forming of persistent links between them. It may also be possible to tell the extent to which links participate in the spread of potential behavioral influences. Since OSS projects change in both social and technical activity over time, static approaches, that either ignore time or simplify it to a few slices, are frequently inadequate to study these networks. On the other hand, ad-hoc dynamic approaches are often only loosely supported by theory and can yield misleading findings. Here we adapt the stochastic actor-oriented models from social network analysis. These models enable the study of the interplay between behavior, influence and network architecture, for dynamic networks, in a statistically sound way. We apply the stochastic actor-oriented models in case studies of two Apache Software Foundation projects, and study code ownership and developer productivity as behaviors. For those, we find evidence of significant social selection effects (homophily) in both projects, but in different directions. However, we find no evidence for the spread (social influence) of either code ownership or developer productivity behaviors through the networks.","2017-02","2025-04-25 15:31:40","2025-04-25 15:31:40","","407-435","","1","22","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our study revealed that Japanese IT companies are rather free riders of OSS, the volume of development contributions are far less than that of utilization. From our previous studies, it was anticipated that some OSS-related factors were affecting the business growth; however, clear evidence has not been found. In autumn 2014, we conducted the questionnaire survey for the third time and this paper presents the survey results as the second report of the continued research. We constructed the simplified Logistic Model to investigate the influential factors on business growth. However, no clear evidence was found as the same as the previous study.

While the benefits resulting from network externality have been examined in the related literature, the effect of free offer on the diffusion of new software has not been formally analyzed. We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters. Our methodology is shown to be applicable for both fixed and dynamic pricing strategies.","2009","2025-04-25 15:31:41","2025-04-25 15:31:41","","207-239","","3","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The ADC can record a temporal signal produced by chromatography and flow-injection analysis. It has two voltage measurement ranges: +/- 2.048 V and +/- 1.024 V, respectively, with 14-bit resolution and a four samples s(-1) sampling rate. The voltage resolution is 0.25 mV and 0.125 mV per one ADC reading for +/- 2.048 V and +/- 1.024 V, respectively. Its dimensions were 100x70x30 mm, and mass was 110 g. We have evaluated its performance, including the linearity and the difference between the two devices. For +/- 1.024 V range, the calibration curve for one ADC and another was D = 7954V 5 and D = 7946V + 30, respectively, where D is an ADC reading, and V is an input voltage. For another range, it was D = 3972V - 3 and D = 3968V + 15, respectively. Their slopes and intercept agreed with each other, and had good linearity, R-2 > 0.9999. We have then successfully applied it to the sequential injection analysis (SIA) of chromium(VI) using diphenylcarbazide as a coloring reagent.

Having a good knowledge of molecular structure is crucial to work out polarity of compounds, intermolecular forces and their relationship with properties. In addition, it is very important to understand the inorganic systems that explain the behaviour of atoms, ions and molecules in understanding the phenomena of organic chemistry [2]. Therefore, the understanding of spatial structures is central to the discipline of chemistry. However, in textbooks molecular structures are represented as two-dimensional objects and as result, students might find difficult to switch from 2D to 3D structures or images. Using 3 dimensional models help students acquire a better understanding of molecular geometry and encourage active learning. Computer visualizations now offer an interesting possible alternative to concrete or physical models [3]. Jmol is one of the most prevalent molecular visualization tools in STEM education. It is a free open source software for interactive molecular visualization. This work describes the implementation of the Jmol visualization tool in a module on General Chemistry for Engineers during the academic year 2016-2017. The goals were three-fold. Firstly, to use the Jmol visualization application as a teaching tool for classroom demonstration. Then, to provide students with the skills to use the molecular visualization tool for their own learning process. Finally, to actively engage students with generation and manipulation of molecular models. Jmol application was used during Lectures to teach about molecular structure. Students then had to download and use the application on their own to complete several worksheets. Later on, Jmol molecular models were also used to aid student understanding of organic chemistry, including isomerism. Additional worksheets and assignments involved the use of Jmol visualization tool. The evaluation of the software implementation on the module was carried out by marking the worksheets and by a survey that was conducted among the students.","2017","2025-04-25 15:31:41","2025-04-25 15:31:41","","9355-9359","","","","","","","EDULEARN Proceedings","","","","","","","","","","","","","ISSN: 2340-1117","","","","","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To achieve this they had to use strategies which allowed them to reach the minimum adaptation development and in this way they could face changes imposed by the market.

In this work we describe some strategies based on free software which can be applied in process reengineering to achieve this goal. In this process is taken into account the emergence of free software which has allowed companies venturing into new ways of performing this reengineering because, by means of collaborative work, they reduced time and costs for many of their processes.","2014-08","2025-04-25 15:31:41","2025-04-25 15:31:41","","197-206","","","42","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there is often a high turnover among contributors (in some projects as high as 80%). The survivability of contributors is influenced by various factors, including their demographics. Research on contributors' survivability must, therefore, consider diversity factors. This study longitudinally analyzed the impact of demographic attributes on survivability in the Flutter community through the lens of gender, region, and compensation. The preliminary analysis reveals that affiliated or Western contributors have a higher survival probability than volunteer or Non-Western contributors. However, no significant difference was found in the survival probability between men and women.","2023","2025-04-25 15:31:41","2025-04-25 15:31:41","","2213-2215","","","","","","","","","","","Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei","","","","","","","","","","","","","","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within the LAT collaboration we support Red Hat Linux, Windows, and are moving towards Mac OS as well for offline simulation, reconstruction and analysis tools. Early on it was decided to use one software system to run our simulations as well as ultimately handle the event processing for real data. We leveraged many existing HEP external libraries (Geant4, Gaudi Framework, ROOT, CLHEP, CMT) to ease the burden on our developers. This strategy of re-using existing software helped us pull together our system quickly and test during our beam tests and data challenges. Now, after launch, we are in a new phase of the project, where we must move forward to support modern operating systems and compilers to get us through the life of the mission. This means upgrading our external libraries as well, which are not under our direct control. Meanwhile, it is crucial to our production system that we carefully orchestrate all upgrades to insure stability. An additional hurtle is that our number of active developers has dwindled dramatically. Many of those left are Windows developers reliant on the Visual Studio development environment, while our user base and production system depend on our Linux distributions.

Our study presents a multi-region geographical analysis of gender inclusion on GitHub. This mixed-methods approach includes quantitatively investigating differences in gender inclusion in projects across geographic regions and investigate these trends over time using data from contributions to 21,456 project repositories. We also qualitatively understand the unique experiences of developers contributing to these projects through a survey that is strategically targeted to developers in various regions worldwide. Our findings indicate that gender diversity is low across all parts of the world, with no substantial difference across regions. However, there has been statistically significant improvement in diversity worldwide since 2014, with certain regions such as Africa improving at faster pace. We also find that most motivations and barriers to contributions (e.g., lack of resources to contribute and poor working environment) were shared across regions, however, some insightful differences, such as how to make projects more inclusive, did arise.

W. Henze “Das Flog der Medusa” (”The Raft of Medusa”), often seen as an example of Henze's political engagement. The author of the article concludes that the oratorio was recognized as a political composition in large part due to the accompanying circumstances of its creation and premiere, but not based on the original idea and its realisation. The author demonstrate “Das Flog der Medusa” like a example of the protest music as a direction that exposes not only fascism, but also any form of social inequality, violence against the person. The study of the features of choral style of “Das Flog der Medusa” reveals parallels in the textural structure between Henze's oratorio and Nono's works of the 1950s (”La victoire de Guernica”, “Il canto sospeso”, “Intolleranza 1960”). The use of political text resources, the operation of individual syllables and phonemes of a literary text, work with multilingual verbal rows, the active use of diagonal texture - all this brings together the choral works of two contemporaries. At the same time, Henze's composition also reflected the searches in the field of vocal timbre, characteristic of other composers of Darmstadt Summer Course - the use of various modifications of speech singing ( Sprech- gesang ), the latest techniques of vocal articulation (vocal tremolo, prolongation of the anterolingual vibrant). All this together allows us to talk about Henz's oratorio as one of the most peculiar choral compositions of the late 1960s.","2024","2025-04-25 15:31:41","2025-04-25 15:31:41","","23-33","","1","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There is a desire to establish means by which the shapes of planar polygons can be measured, characterized, and compared. I present the ShrinkShape2 toolbox, a completely redesigned set of end-user tools (an advancement of its precursor ShrinkShape) that is implemented seamlessly in the free and opensource R and SAGA GIS environments. This free, efficient, and accessible environment provides a multidimensional, rotation invariant, scale-controlled method for characterizing and comparing planar shapes and tools for visualizing results. ShrinkShape2 incrementally buffers polygons internally until the point of extinction; at each shrinking phase a series of summary metrics are computed to form spectra of index values that characterize general characteristics of shape structure and complexity. Demonstrations with simple synthetic shapes, political boundary maps, and a sample sub-Arctic pond demonstrate the ability to assess boundary complexity, pinch-points, and identify holes within larger shapes. For perfectly convex and compact shapes, perimeter decompositions will decrease linearly and area decompositions will decrease according to one limb of a second-order polynomial function relative to the cumulative shrinking distance.

This cross-sectional study was conducted with a sample of 402 preschool children aged 1-5 years, from Santa Cruz do Sul, a Southern city in Brazil. Mothers answered questions about environmental, demographic, and socioeconomic characteristics. Behavior variables as use of dental floss (study outcome) and dental attendance were also evaluated. Poisson regression analysis with robust variance through a hierarchical approach was used to investigate the association of explanatory variables for use of dental floss. Prevalence ratio (PR) and 95% confidence intervals (95%CI) were estimated. The mean sample age was 3.32 years (standard deviation [SD] 1.10). Of the included children, 291 (73.12%) did not use dental floss. The environmental model indicated that children who attended daycare (PR 2.53; 95%CI 1.39-4.60) and those whose parents were members of volunteer networks (RP 1.58; 95%CI 1.02-2.46) were more likely to use dental floss.

A vulnerability adds functionality to a system, as it allows an adversary to misuse or abuse the system, while a canonical bug is an incomplete or incorrect implementation of a requirement, and thus degrades the functionality of the system. This difference can affect the fixing process of vulnerabilities. By mining the repositories of 6 open source projects, we characterize the differences in the fixing process between vulnerabilities and canonical bugs, highlighting critical issues which could represent challenges for future research. Results of our study demonstrate that: (i) more re-assignments (than the ones observed in canonical bugs) are required for finding the developers able to handle vulnerability-related bugs, (ii) developers' security-related skills should be profiled, to improve the efficiency of the security bug assignment tasks, and, consequently, reduce the re-assignments, and (iii) vulnerabilities require more effort, contributors and time to define the fixing strategy but smaller time to fix than canonical bugs.

Nowadays the equation has been extended in order to be applicable not only to sand beaches but also to gravel beaches. In this paper Phoebus user-friendly software for an automatic use of the extended parabolic bay shape equation is presented. The software enables both technical experts and non-professionals to conduct expeditious analysis in order to evaluate the evolution and equilibrium conditions of embayed littoral beaches lying between natural headlands or man-made structures, as well as to artificially recreate stable embayed beaches by building new artificial structures on open beaches. The software can be also used for coastal planning, to anticipate beach modifications in response to new building or to changes in pre-existing structures. Highlights 1. Development of a free software to automatically compute embayed beach planform 2. The system can be used on every type of beach image 3. The software allows to display the planform both for sand and gravel beaches 4. Software reliability was demonstrated for natural and artificial bay beaches.","2013-09","2025-04-25 15:31:42","2025-04-25 15:31:42","","165-173","","3","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The text aims to question the fact that the market develops proprietary software, as opposed to the collaborationist ideal of the free software movement, that enables digital inclusion and participation, which is intended to be adopted through public policies, extending its use to the public education agencies. It also discusses the concept of free software and its adoption in college education through resolutions adopted by the Brazilian state, analyzing the experience of the Journalism Course at Federal University of Uberlandia - UFU - on the use of free software Scribus. Methodologically, document research was used to find the data and information provided by the federal government and the object institution of the analysis. A comparison with a similar proprietary software model is made, highlighting that the use of free software is reliable, allowing to develop the communitarian and collaborationist spirit needed in the university environment, expanding the knowledge and not merely the “dressage at the pressing of buttons”. It is noted, based on the documents, that the initiative is still seen with resistance and its use, even in public CEIs (College Education Institutions), needs to be intensified.","2014-08","2025-04-25 15:31:42","2025-04-25 15:31:42","","207-222","","2","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Typically, the developers create a stable branch for each old stable version, deploy security patches on the branch, and release fixed versions at regular intervals. As such, old-version applications in production environments are protected from the disclosed vulnerabilities in a long time. However, the rapidly growing number of OSS vulnerabilities has greatly strained this patch deployment model, and a critical need has arisen for the security community to understand the practice of security patch management across stable branches. In this work, we conduct a large-scale empirical study of stable branches in OSS projects and the security patches deployed on them via investigating 608 stable branches belonging to 26 popular OSS projects as well as more than 2,000 security fixes for 806 CVEs deployed on stable branches. Our study distills several important findings: (i) more than 80% affected CVE-Branch pairs are unpatched; (ii) the unpatched vulnerabilities could pose a serious security risk to applications in use, with 47.39% of them achieving a CVSS score over 7 (High or Critical Severity); and (iii) the patch porting process requires great manual efforts and takes an average of 40.46 days, significantly extending the time window for N-day vulnerability attacks. Our results reveal the worrying state of security patch management across stable branches. We hope our study can shed some light on improving the practice of patch management in OSS projects.","2022","2025-04-25 15:31:42","2025-04-25 15:31:42","","767-777","","","","","","","","","","","Assoc Comp Machinery; ACM SIGWEB; LIRIS; Univ Lyon; Inst Natl Sci Appliquees; Eurecom","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is because both the quality of these software products is high enough for these applications and the support of software could fulfill the requirement. In general, when one wants to adopt OSS as a part of computer systems, it is required to examine the functional requirement (FR) for the OSS as well as nonfunctional requirement (NFR). In the previous paper, we focused on NFR of OSS and proposed an evaluation method based on the maturity model of OSS community. Based on the model, we tried to evaluate four major OSS communities. For the evaluation, we used human knowledge of targeted OSS community. However it was not clear how to evaluate individual OSS project in OSS community. In this paper, we focused on continuity of OSS project, as it is one of the most important factors for users to make a decision. In order to evaluate continuity, we proposed a growth model of OSS project, which is based on the size and activity of OSS Project. We evaluated the growth model using information retrieved from OSS communities from both OSS community sites and source code repositories. (C) 2015 The Authors.

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.","2016-05","2025-04-25 15:31:42","2025-04-25 15:31:42","","","","2","25","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As a case study, we extracted and analyzed the review process of Android Open Source Project (AOSP). To the best of our knowledge, this is the first research constructing social networks from mining a peer review repository.

Data from previous Studies were also reworked to fit into the themes being monitored. Temporal trends were evaluated using polynomial curve Fitting, which were confirmed by statistical analyses. The extracted trends indicate a steady increase in air temperature, relative humidity and annual rainfall, while wind speed declined. The standardized seasonal rainfall Shows all autumn trend that approximates the annual trend With amplitude of live years, while rainfall during the winter declines and inclines during above the long-term average during spring. Concurrently, sodium, sulfate and chloride soil concentrations increased rapidly in the late 1990s, together with increases ill the very fine sand fraction, which reflects the active erosion and deposition processes associated with recent human interference. There is a general process of recharging plant species diversity (long-term records; 122 perennials and 104 annuals) in the late 1990s following a sizeable decline; 26 perennials with declining density and spatial occupation call be considered at threat. Some of these species are transient and show a three-year cycle of species replacement (turnover when related to added species). The change ill the diversity of perennial species is allied to changes in rainfall, temperature and wind speed related to the climatic, salinity, bicarbonate, calcium, and Sulfate of the edaphic variables. This also applies to endangered species, where especially air temperature and Soil sulfates are the most determinant driving factors. Further, a shift of the rainfall above the long-term average from winter to spring elucidates the trend of change detected ill the diversity. It is concluded that the diversity of biotops (spatial heterogeneity in habitats) ill the area is the influential base for the biodiversity and is greatly affected by human impact. Concurrently, climatic changes and the associated environmental degradation of soil resources are more cyclic (recurring) phenomena, which reflect specific feedback effects oil biodiversity in the region.","2008","2025-04-25 15:31:42","2025-04-25 15:31:42","","289-309","","","","","","","","","","","UNESCO","","","","","","","","","","","","","","","Lee, C; Schaaf, T","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To overcome the problem of inherent computational complexity, a fractional-order filter is applied to approach the virtual controller and its fractional-order derivative in each step of the backstepping procedure. The barrier Lyapunov function (BLF) is employed to handle the state constraints, and finite-time stability criteria on the basis of fractional-order Lyapunov method are introduced to prove the finite-time convergence of the tracking error into a small region around the origin. It is shown that all the solutions of the closed-loop system are bounded, while the state constraints are satisfied within a predetermined finite time. Finally, two examples are provided to demonstrate the effectiveness of the presented control scheme.","2024-07-30","2025-04-25 15:31:42","2025-04-25 15:31:42","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The carriers must integrate their core legacy mainframe operation support systems (OSS) with new generation components that can handle the requirements posed by new service offerings, which means the NG-OSS should pay attention to customers rather than networks. This paper examines the legacy OSS frame with its main component and analysis which part should be weakened or converged, and which part should be enhanced or updated.

The corresponding model extends a recent optimization procedure introduced to describe flame propagation in heterogeneous media featuring composition variations (equivalence ratio and temperature) in the fresh reactants or containing residual burned gases (RBG). It is based on the use of an optimized virtual species and a tabulation of the pre-exponential coefficient of an Arrhenius law. The main results of high activation energy asymptotics (AEA) are first recalled to put in evidence the key parameters and the dependence of the ignition delay on the corresponding quantities. The optimization procedure is then applied to these parameters, namely, the pre-exponential factor K and the activation energy E-a of the associated single-step Arrhenius law. An efficient tabulation method benefiting from both rapid access and low storage is proposed for the composition variable (the mixture fraction, in the present case). Finally, the restitution of both ignition and propagation features is ensured through the consideration of the cross-over temperature. The performance of the resulting model is then assessed through comparisons with data obtained from detailed chemistry computations used as reference in several conditions of increasing complexity.

The method starts by randomly fragmenting a BAG, YAC or PAC to 8-12 kb pieces and subcloning those into lambda phage. Insert-ends of these clones are sequenced and overlapped to create a partial map. Complete sequencing is then done on a minimal tiling path of selected subclones, recursively focusing on those at the edges of contigs to facilitate mergers of clones across the entire target. To reduce manual labor, PCR processes have been adapted to prepare sequencing templates throughout the entire operation. The streamlined process can thus lend itself to further automation. The OSS approach is suitable for large-scale genomic sequencing, providing considerable flexibility in the choice of subclones or regions for more or less intensive sequencing. For example, subclones containing contaminating host cell DNA or cloning vector can be recognized and ignored with minimal sequencing effort; regions overlapping a neighboring clone already sequenced need not be redone; and segments containing tandem repeats or long repetitive sequences can be spotted early on and targeted for additional attention.","1997","2025-04-25 15:31:42","2025-04-25 15:31:42","","25-34","","","2985","","","","PROCEEDINGS OF THE SOCIETY OF PHOTO-OPTICAL INSTRUMENTATION ENGINEERS (SPIE)","","","","Int Biomed Opt Soc; Soc Photo Opt Instrumentat Engineers; Amer Soc Laser Med & Surg Inc","","","","","","","","","","","","","","","Cohn, GE; Soper, SA; Katzir, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the drying characteristics of Calotropis gigantea pods on microwave radiation by using different drying methods, different microwave powers, and different time periods, are studied, and the corresponding impacts on fiber quality are analyzed. The experimental results show that obtaining Calotropis gigantea seed fibers by microwave heating the pods is feasible. Compared to natural air drying and hot air drying, the microwave drying (MW can significantly improve the drying efficiency and reduce the drying time by more than 5 times. The microwave power has considerable influences on the drying rate. However, the fiber strength and break elongation are reduced with the increase of microwave power due to fiber structural change caused by the high temperature inside the pod. Compared with intermittent radiation, the moisture loss rate of the pods is greater in continuous radiation mode, but the pod internal temperature is higher, which is harmful to the quality of the fibers. Varying power radiation, which uses lower power first, then higher, could shorten drying time without impeding the pods' abdominal suture broadening.","2015","2025-04-25 15:32:40","2025-04-25 15:32:40","","251-258","","5","66","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, sometimes students are demotivated to contribute due to entrance barriers. On the other hand, gamification is widely used to engage and motivate people to accomplish tasks and improve their performance. The goal of this work is to analyze the use of gamification to orient and motivate undergraduate students to overcome onboarding barriers and engage to OSS projects. To achieve this goal, we implemented four gaming elements (Quests, Points, Ranking, and Levels) in GitLab and assessed the environment by means of a study conducted with 17 students, within a real OSS project (JabRef). At the end of the study, the students evaluated their experience through a questionnaire. We found that the Quest element helped to guide participants and keep them motivated and points helped by providing feedback on students' performed tasks. We conclude that the gamified environment oriented the students in an attempt to make a contribution and that gamification can motivate and orient newcomers' to engage to OSS projects.","2017","2025-04-25 15:32:40","2025-04-25 15:32:40","","36-42","","","","","","","","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; Assoc Comp Machinery Special Interest Grp Software Engn; EXACTAS UBA; Soc Argentina Informatica; Fundac Investigac & Desarrollo TIC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system's sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries. Specifically, we leveraged a weighted combination of semantics, lexical, and shallow features in conjunction with the Random Forest ensemble learning method. Finally, we discuss the practical applicability of our classifier for mapping and visualizing quality-related concerns into the codebase with an example from the Derby project. To summarize, this work represents an effort and an early awareness to improve the underlying management of issue tracking systems and stakeholder requirements in open-source communities.","2021","2025-04-25 15:32:40","2025-04-25 15:32:40","","12-23","","","","","","","","","","","IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The main users are biologists and related life scientists with no or little knowledge of image processing. In this review, we give an overview of available tools and guidelines about which tools the users should use to segment fluorescence micrographs. We selected 15 free tools and divided them into stand-alone, Matlab-based, ImageJ-based, free demo versions of commercial tools and data sharing tools. The review consists of two parts: First, we developed a criteria catalogue and rated the tools regarding structural requirements, functionality (flexibility, segmentation and image processing filters) and usability (documentation, data management, usability and visualization). Second, we performed an image processing case study with four representative fluorescence micrograph segmentation tasks with figure-ground and cell separation. The tools display a wide range of functionality and usability. In the image processing case study, we were able to perform figure-ground separation in all micrographs using mainly thresholding. Cell separation was not possible with most of the tools, because cell separation methods are provided only by a subset of the tools and are difficult to parametrize and to use. Most important is that the usability matches the functionality of a tool. To be usable, specialized tools with less functionality need to fulfill less usability criteria, whereas multipurpose tools need a well-structured menu and intuitive graphical user interface.","2015-01","2025-04-25 15:32:40","2025-04-25 15:32:40","","39-53","","1","257","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 15:32:41","2025-04-25 15:32:41","","477-512","","4","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Policy, therefore, should not only consist of substituting GNU/LINUX for proprietary software in running the latest and most expensive hardware, but also of lowering these latter costs themselves. Later sections focus on the link between the choice of software and path-dependency (i.e. the notion that if one system gets ahead, it tends to lock out alternatives in the manner described by Brian Arthur). We suggest that the problem of proprietary lock-in in developing countries has been greatly accentuated by piracy of Microsoft operating systems and that the result is a stagnation of the technological capabilities in software that these countries need so badly.","2003","2025-04-25 15:32:41","2025-04-25 15:32:41","","25-33","","1","29","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The goal of this work is to develop a model of integration of educational free software to the teaching-learning process of Artificial Intelligence. The authors use several research methods: historical-logical, analysis and synthesis, functional-structural-systemic and modeling. The model has three fundamental components. The conceptual component represents the principles and their theoretical foundations. The structural component represents the main elements that intervene in the integration. The instrumental component constitutes the materialization of the model and contains three stages: preparation, execution and evaluation.

It would be useful to understand how to get such a project to accept a process improvement proposal and hence to perform process innovation. We want to determine an effective and feasible qualitative research method for studying the above question. We present (narratively) a case study of how we worked towards and eventually found such a research method. The case involves four attempts at collecting suitable data about innovation episodes (direct participation (twice), polling developers for episodes, manually finding episodes in mailing list archives) and the adaptation of the Grounded Theory data analysis methodology. Direct participation allows gathering rather rich data, but does not allow for observing a sufficiently large number of innovation episodes. Polling developers for episodes did not prove to be useful. Using mailing list archives to find data to be analyzed is both feasible and effective. We also describe how the data thus found can be analyzed based on the Grounded Theory Method with suitable adjustments. By-and-large, our findings ought to apply to studying various phenomena in OSS development processes that are similarly heavyweight and infrequent. However, specific details may block this possibility and we cannot predict which details that might be. The amount of effort involved in direct participation approaches to qualitative research can easily be underestimated. Also, survey approaches are not well-suited for many process issues in OSS, because too few developers are sufficiently process-conscious. An approach based on passive observation is a viable alternative in the OSS context due to the availability of large amounts of fairly complete archival data.","2011-08","2025-04-25 15:32:41","2025-04-25 15:32:41","","514-537","","4, SI","16","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Henceforth, Literature witnesses the evolution of SRGMs in terms of different assumptions, parameters, performance etc. This study is an attempt to model reliability growth phenomenon for Open Source Software (OSS). As the development process followed by OSS significantly differs from proprietary software, traditional software engineering SDLC models can't be followed for its development. OSS development procedure does not incorporate a dedicated testing phase and therefore negligible effort expenditure is done on testing of software prior its release. The volume of volunteer participation in its operational phase thus becomes a significant criterion in the representation of its reliability growth. Also, the impact of sudden changes in fault detection process (change-point) due to several reasons like variations in fault density, irregular team size, volunteer expertise etc is captured in proposed SRGM. This paper suggests a reliability model based on user growth with the concept of change point to better cater the heterogeneity in software failure process. Failure data of GNOME 2.0 is used in this paper reliability growth analysis. Unknown parameters are estimated using Least Square Estimation regression technique. Performance inspection of proposed SRGM is carried out using goodness-of-fit criteria like Mean square error (MSE), Coefficient of Determination (R-2), Predictive Ratio Risk (PRR), and Predictive Power (PP). The study recommends that introduction of the change-point in SRGM improves prediction capability of the model and hence establishes an evidence of its applicability.","2017","2025-04-25 15:32:41","2025-04-25 15:32:41","","248-253","","","","","","","International Conference on Reliability Infocom Technologies and Optimization Trends and Future Directions","","","","Amity Univ Uttar Pradesh, Amity Inst Informat Technol; Comp Soc India; IEEE; IEEE UP Sect","","","","","","","","","ISSN: 2469-875X","","","","","","Shukla, B; Khatri, SK; Kapur, PK","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""
-"VMNYKMAY","journalArticle","2024","Luo, Du","Quantitative Analysis of Fish Morphology Through Landmark and Outline-based Geometric Morphometrics with Free Software","BIO-PROTOCOL","","","10.21769/BioProtoc.5087","","Morphology underpins key biological and evolutionary processes that remain elusive. This is in part due to the limitations in robustly and quantitatively analyzing shapes within and between groups in an unbiased and high- throughput manner. Geometric morphometrics (GM) has emerged as a widely employed technique for studying shape variation in biology and evolution. This study presents a comprehensive workflow for conducting geometric morphometric analysis of fish morphology. The step-by-step manual provides detailed instructions for using popular free software, such as the TPS series, MorphoJ, ImageJ, and R, to carry out generalized Procrustes analysis (GPA), principal component analysis (PCA), discriminant function analysis (DFA), canonical variate analysis (CVA), mean shape analysis, and thin plate spline analysis (TPS). The Momocs package in R is specifically utilized for in-depth analysis of fish outlines. In addition, selected functions from the dplyr package are used to assist in the analysis. The full process of fish outline analysis is covered, including extracting outline coordinates, converting and scaling data, defining landmarks, creating data objects, analyzing outline differences, and visualizing results. In conclusion, the current protocol compiles a detailed method for evaluating fish shape variation based on landmarks and outlines. As the field of GM continues to evolve and related software develops rapidly, the limitations associated with morphological analysis of fish are expected to decrease.

The intended software accounts for complex interrelations of the structural components as well as for mathematical optimization schemes. However, we emphasize the importance of an easy access to the code and the possibility to implement individual ideas. The claims and basic conditions demand a strategy, which is different to the software development of commercially used products. Due to the steady fluctuation of the software developers merely temporary teams and an unforced community of users result. Their feedback and loyalty to the software project are mainly based on individual benefit but may also be motivated by idealism. From our point of view, civil engineering has a broad base to use software development as an interface between education and profession. We discuss our experience for such a project and about an experiment to benefit from building up a social network in this context.

However, onboarding to an OSS project brings various challenges, including finding a suitable task among various open issues. Selecting an appropriate starter task requires newcomers to identify the skills needed to solve a project issue and avoiding tasks too far from their skill set. However, little is known about how effective newcomers are in identifying the skills needed to resolve an issue. We asked 154 undergrad students to evaluate issues from OSS projects and infer the skills needed to contribute. Students reported a total of 94 skills, which we classified into 10 categories. We compared the students' answers to those collected from 6 professional developers. In general, students misidentified and missed several skills (f-measure=0.37). Students had results closer to professional developers for skills related to database, operating infrastructure, programming concepts, and programming language, and they had worse results in identifying skills related to debugging and program comprehension. Our results can help educators who seek to use OSS as part of their courses and OSS communities that want to label newcomer-friendly issues to facilitate onboarding of new contributors.","2022","2025-04-25 15:32:41","2025-04-25 15:32:41","","174-183","","","","","","","European Conference on Software Maintenance and Reengineering","","","","IEEE; IEEE Comp Soc","","","","","","","","","ISSN: 1944-2793","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Meanwhile, software companies have successfully launched programs like Google Summer of Code (GSoC) and FindBugs “fixit” to contribute to open-source projects. Inspired by the success of these programs, we propose GitHub-OSS Fixit, a team-based course project where students are taught to contribute to open-source Java projects by fixing bugs reported in GitHub. We described our course outline to teach students SE concepts by encouraging the usages of several automated program analysis tools. We also included the carefully designed instructions that we gave to students for participating in GitHub-OSS Fixit. As all lectures and labs are conducted online, we think that our course design could help in guiding future online SE courses. Overall, our survey results show that students think that GitHub-OSS Fixit could help them to improve many skills and apply the knowledge taught in class.

By introducing the finite-time stability criteria from fractional-order Lyapunov method, it is verified that the tracking error converges to a small neighborhood near the zero and the full-state constraints are satisfied within a predetermined finite time.

In this study, our objective was to advance the practicality of drug-coated floss as an intra gum pocket drug delivery system. The initial design of this delivery system has been previously reported by us. Here, we advance the concept further through in vitro and in vivo evaluation. A floss piece was dip coated in the middle section with model molecules leaving free ends for holding. Porcine gum tissues were used ex vivo and in vivo to evaluate the coated floss, including effect of coating thickness on delivery efficiency, ability to deliver more than one type of molecule (one hydrophilic and one hydrophobic), mechanical properties using a scratch test, and finally retention of delivered material in vivo in the porcine model. After reaching a certain coating thickness, the delivery efficiency of the coated floss decreased, indicating the presence of an optimal coating thickness. Hydrophobic and hydrophilic molecules were successfully coated and delivered with high efficiency into gum pockets. The scratch test indicated that the coatings were resilient. Lastly, the in vivo analysis showed that the drug coating was delivered into the porcine gum pocket with about 65% efficiency, and the coatings could maintain extended residency within the gum pocket despite the native adverse environment of the oral cavity. Overall, this data shows that drug-coated floss can act as a drug delivery vehicle and has potential to provide a minimally invasive and practical method for the delivery of drugs into the gum pockets.","2022-06-29","2025-04-25 15:32:41","2025-04-25 15:32:41","","28663-28670","","25","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I trace the learning trajectories of two participants from high school until they enter the professional workforce and beyond. I argue that FLOSS participation represents an ideal networked form of learning as it provides both socio-cognitive support for short term activities and also socio-temporal support for long term participation and learning. It is a unique form of apprenticeship that exists concurrently with formal educational experiences but unlike traditional apprenticeship experiences it succeeds by spanning different spatialities - place/space and technology mix and temporal scales.","2018","2025-04-25 15:32:42","2025-04-25 15:32:42","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While previous research recognizes the significance of trust in an organizational setting, there is a lack of understanding in how trust is exhibited in OSS distributed teams, where there is an absence of direct, in-person communications. To foster trust and collaboration in OSS teams, we need to understand what trust is and how it is exhibited in written developer communications (e.g., pull requests, chats). In this paper, we first investigate various dimensions of trust to identify the ways trusting behavior can be observed in OSS. Next, we sample a set of 100 GitHub pull requests from Apache Software Foundation (ASF) projects, to analyze and demonstrate how each dimension of trust can be exhibited. Our findings provide preliminary insights into cues that might be helpful to automatically assess team dynamics and establish interpersonal trust in OSS teams, leading to successful and sustainable OSS.","2023","2025-04-25 15:32:42","2025-04-25 15:32:42","","19-24","","","","","","","International Conference on Software Engineering-New Ideas and Emerging Technologies Results Track","","","","IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; Melbourne Convent Bur; State Govt Victoria; CSIRO; Huawei; Monash Univ; Meta; Google; AWS; Monash Univ; Dragon Testing Technol; IBM; Univ Melbourne; RMIT Univ","","","","","","","","","ISSN: 2832-7624","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Four diamictons interbedded with glaciomarine and glaciofluvial sediments are exposed in a large gravel pit situated above the post-glacial marine limit. The interpretation of these sediments has implications for the history of both the inland ice and the Norwegian Channel Ice Stream. During a Middle Weichselian interstadial, a large glaciofluvial delta prograded into a shallow marine environment along the coast of Jaeren. A minor glacial advance deposited a gravelly journal of Quaternary Science diamicton, and a glaciomarine diamicton was deposited during a following marine transgression. This subsequently was reworked by grounded ice, forming a well-defined boulder pavement. The boulder pavement is followed by glaciomarine clay with a lower, laminated part and an upper part of sandy clay. The laminated clay probably was deposited under sea-ice, whereas more open glaciomarine conditions prevailed during deposition of the upper part. The clay is intersected by clastic dykes protruding from the overlying, late Weichselian till. Preconsolidation values from the marine clay suggest an ice thickness of at least 500 m during the last glacial phase. The large variations in sea-level probably are a combined effect of eustasy and glacio-isostatic changes caused by an inland ice sheet and an ice stream in the Norwegian Channel.

This paper presents and evaluates a maturity model (HAVOSS) for handling vulnerabilities in third party OSS and COTS components. The maturity model was designed by first reviewing industry interviews, current best practice guidelines and other maturity models. After that, the practices were refined through industry interviews, resulting in six capability areas covering in total 21 practices. These were then evaluated based on their importance according to industry experts. It is shown that the practices are seen as highly important, indicating that the model can be seen as a valuable tool when assessing strengths and weaknesses in an organization's ability to handle firmware updates.","2018","2025-04-25 15:32:42","2025-04-25 15:32:42","","81-97","","","11271","","","","Lecture Notes in Computer Science","","","","Leibniz Univ Hannover","","","","","","","","","ISSN: 0302-9743","","","","","","Kuhrmann, M; Schneider, K; Pfahl, D; Amasaki, S; Ciolkowski, M; Hebig, R; Tell, P; Klunder, J; Kupper, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

New so-called third generation (3G) or triple play services can be delivered to the market by means of using these architectures as well as respective IT support systems. Furthermore, various market players, stakeholders or alliances will come up at the telecommunications arena. The paper will systematic ally consider all these subject matters and elaborate that the use of New Generation Systems and Software (NGOSS) principles will leverage the OSS/BSS as well as IMS/SDP promise. In other words, to provide efficiently IMS/SDP based services requires an “IMS/SDP ready” OSS/BSS. There will be lots of well-known as well as quite a few new features to be provided by such an OSS/BSS. One example is that an “IMS/SDP ready” OSS/BSS does not only provide all the existing services very quickly.. it must also be able to support the design and creation of new types of services including new types of network/IT resources which allow these new kinds of services at all.

Trees that produce thousands of flowers at densities higher than that of herbs and produce much more nectar than the latter can be such keystone structures. However, there is a lack of specific information on trees, both native and alien, and their flower visitors in urban/suburban contexts, which blurs the conservation role that such species can perform. In 2019 and 2020, we thoroughly recorded the flower visitors to a silk-floss tree in suburban Guadalajara, Mexico. To our knowledge, this is the first comprehensive inventory of silk-floss tree flower visitors. We documented 79 species/morphospecies of insects; eight of birds, and one of mammals visiting the flowers. All, except two, are native to the region; three are endemic/quasi-endemic to Mexico. Besides direct and indirect floral resources, the silk-floss tree offered perches, resting/hiding cover, nesting substrate, and seed fibres used by several birds, and feeding substrate for gleaning insectivorous birds. Four species are on one or more conservation listings: monarch butterfly (endangered), pink-spotted swallowtail (vulnerable), sparkling-tailed hummingbird (threatened), and lesser long-nosed bat (near-threatened). Our data supports that small patches can enhance the quality of urban green spaces, and that rather than geographic origin, flower output drives visitation. Alien trees can be pollination enhancement `devices' for imperilled pollination networks. Silk-floss trees are a potential option for conservation-oriented urban greening, as well as to contribute to enhancing human enjoyment of nature, and provide opportunities for public outreach.","2023-12-31","2025-04-25 15:32:42","2025-04-25 15:32:42","","2028-2038","","45-48","57","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Automated support for retrieving relevant information and particularly for recognizing discussants' intentions (e.g., suggesting, complaining) can support analysts, and allow them to increase the performance of this task. Online discussions are almost synchronous written conversations that can be analyzed applying computational linguistic techniques that build on the speech act theory. Our approach builds on this observation. We propose to analyze OSS mailing-list discussions in terms of the linguistic and non-linguistic acts expressed by the participants, and provide a tool-supported speech-act analysis method.

In the past, forest landscape has changed dramatically, especially in periods of forest over-exploitation. Previous studies in some Trentino sub-regions (Val di Fassa, Paneveggio) have identified these changes and the current trend of forest growth at the expenses of open areas, such as pastures and grasslands, due to the abandonment of rural areas. This phenomenon leads to the rapid Alpine landscape change and profoundly affects the ecological features of mountain ecosystems. To be able to monitor and to take future actions about this trend it is fundamental to know in detail the historical situation of the progressive changes on the land use that occurred over Trentino. The work aims to comprehensively reconstruct the forest cover of whole Trentino at high resolution (5m x 5m pixels) using a series of maps spanning a long period, consisting in historical maps, aerial images, remote sensed information and historical archives. The datasets were archived, processed and analyzed using the Free and Open Source Software (FOSS) GIS GRASS and QGIS. Historical maps include Atlas Tyrolensis (dated 1770), Theresianischer Kataster (dated 1859) and Italian Kingdom Forest Map (IKFM) of 1936. The aerial imagery dataset includes aerial images taken in 1954, which have been orthorectified during this research, and orthophotos available for years 1973, 1994, 2000, 2006, 2010 and 2016. Remote sensed information includes Landsat and recent Lidar data, while historical archives consist mostly in Forest Management Plans available since around 1950. The versatility of the wide variety of modules supplied from the FOSS GRASS and QGIS enabled to perform a diverse set of analysis and pre-processing (e.g.:orthorectification) on a heterogeneous dataset of input images. We will focus on the different strategies and methodologies implemented in the FOSS GIS used to process the various types of geographic data, challenges for the future of the research and the fundamental role of the FOSS systems in this process. Quantifying forest change in the time-span of our dataset can be used to perform further analysis on ecosystem services, such as protection from soil erosion, and on modification of biome diversity and to create future change scenarios.","2019","2025-04-25 15:32:42","2025-04-25 15:32:42","","71-78","","","42-4","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences","","","","ISPRS","","","","","","","","","ISSN: 1682-1750 Issue: W14","","","","","","Brovelli, MA; Marin, AF","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, previous work shows that OSS newcomers often face several barriers to contribute, which lead them to lose motivation and even give up on contributing. A well-known way to help newcomers overcome initial contribution barriers is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in OSS projects. Studying mentors' perspectives on the barriers that newcomers face play a vital role in improving onboarding processes; yet, OSS mentors face their own barriers, which hinder the effectiveness of the strategy. Since little is known about the barriers mentors face, in this paper, we investigate the barriers that affect mentors and their newcomer mentees. We interviewed mentors from OSS projects and qualitatively analyzed their answers. We found 44 barriers: 19 that affect mentors; and 34 that affect newcomers (9 affect both newcomers and mentors). Interestingly, most of the barriers we identified (66%) have a social nature. Additionally, we identified 10 strategies that mentors indicated to potentially alleviate some of the barriers. Since gender-related challenges emerged in our analysis, we conducted nine follow-up structured interviews to further explore this perspective. The contributions of this paper include: identifying the barriers mentors face; bringing the unique perspective of mentors on barriers faced by newcomers; unveiling strategies that can be used by mentors to support newcomers; and investigating gender-specific challenges in OSS mentorship. Mentors, newcomers, online communities, and educators can leverage this knowledge to foster new contributors to OSS projects.","2018-12","2025-04-25 15:32:42","2025-04-25 15:32:42","","679-714","","3-6, SI","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Also, OSS projects will heavily depend the environment of internet network. This paper focuses on the irregular fluctuation of operation performance measures for OSS project management. We apply the double jump diffusion process models to the noisy cases in the operation of OSS. In particular, the maintenance effort is estimated by the stochastic differential equation model in terms of OSS project management. Moreover, we propose the method of maintenance effort management based on the double jump diffusion process model considering the irregular fluctuation of performance for OSS projects. Thereby, it will be helpful for the OSS developers and managers to understand the maintenance effort status of OSS from the standpoint of OSS project management. Also, we analyze actual data to show numerical examples of the proposed models with the characteristics considering noisy and jump of OSS projects.","2022-05","2025-04-25 15:32:43","2025-04-25 15:32:43","","411-426","","1, SI","312","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standardization in OSS quality is of vital importance as a communication vehicle for stakeholders in identifying and selecting high-quality products. Thus, meta-models help to define a standardized language and enable to propose quality models that can be used to perform comparable measurements.Objective Considering the lack of a comprehensive meta-model of OSS quality in the literature, there appears a need to see a more complete picture of OSS quality and to represent its concepts more formally. Therefore, in this study, it is aimed to develop a solid base for a comprehensive meta-model of OSS quality to create a common understanding among stakeholders.Method A systematic way has been followed toward developing a common structure, defining a consistent terminology and, finally, providing a meta-model of OSS quality. In this context, (1) the common structure of the quality models for OSS has been investigated, (2) the terms of the general-purpose meta-models of software quality have been analyzed based on the international standards, and (3) the terms of the quality models for OSS have been mapped with the elements of these meta-models.Results An initial meta-model of OSS quality, which employs a unified structure from the OSS quality models and eliminates the inconsistencies determined in the general-purpose meta-models of software quality, has been proposed and an implementation of this meta-model has been demonstrated.Conclusion This initial meta-model of OSS quality with a standard terminology can be taken as a guide by researchers who will propose or revise their OSS quality models. It will allow developing multiple OSS quality models with homogenous structure and terms, and also enable comparing the evaluation results obtained by these models.","2023-09","2025-04-25 15:32:43","2025-04-25 15:32:43","","721-773","","3","31","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, OSS, when viewed as a value creation process rather than `free' software, provides businesses with value through access to knowledge and innovation capacity resident in online communities. This conceptualisation, which we label `strategic open source' requires firms to rethink their strategy and processes as there is a shift in focus from ownership to openness and collaboration with external parties. Nonetheless, the emergence of OSS poses a puzzle for conceptions of organisational theory. Therefore, a theorising process is needed in order to develop a deeper understanding of how value is created and captured with OSS. Using a field study of eleven European firms, this paper explores the creation and capture of business value from strategic open source. The findings reveal that while decision makers look to open innovation initiatives like OSS for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.

Here we present a deployed system deriving detailed information on hemodynamics and vessel wall stresses from common tomography data in a simple and efficient way. The system is suited for direct use e.g. by radiologists or cardiologists in medical planning and clinical research settings. Up to now, detailed numerical simulations of similar kinds have required the effort of specialized, large, multi-disciplinary groups. The deployment of the new system is based on resources maintained by the nationally funded german MediGRID project. This assures broad accessibility, low or no set-up and maintenance costs and a high security level. The implementationdesign facilitates intuitive interactive usage for user-intensive parts and full exploitation of high-performance-computing for the computationally intensive components of the processing pipeline. Virtual vascular surgery is supported, including the placement of stents, clipping of aneurysms, and vessel dilation. The effect of such interventions can be explored, including parametric effects like stent position or porosity, as part of the intervention planning. Physical fields of interest like pressure, wall shear stress, blood flow volume rate, or their correlations can be inspected as time series or as interactive three-dimensional scenes. The grid related parts of the workflow are controlled readily over a web interface.","2009","2025-04-25 15:32:43","2025-04-25 15:32:43","","149+","","","25","","","","IFMBE Proceedings","","","","IUPESM; Int Org Med Phys (IOMP)","","","","","","","","","ISSN: 1680-0737 Issue: 5","","","","","","Dossel, O; Schlegel, WC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The voluntary, self-organizing distribution of decentralized labor and the distinct nature of some OSS projects intensifies this challenge. Mentors, who work closely with newcomers, develop strategies to recommend tasks. However, to date neither the challenges mentors face in recommending tasks nor their strategies have been formally documented or studied. In this paper, we interviewed mentors of well-established OSS projects (n=10) and qualitatively analyzed their answers to identify both challenges and strategies related to recommending tasks for newcomers. Then, we employed a survey (n=30) to map the strategies to challenges and collect additional strategies. Our study identified 7 challenges and 13 strategies related to task recommendation. Strategies such as “tagging the issues based on difficulty,” “adding documentation,” “assigning a small task first and then challenge the newcomers with bigger tasks:' and “dividing tasks into smaller pieces” were frequently mentioned as ways to overcome multiple challenges. Our results provide insights for mentors about the strategies OSS communities can use to guide their mentors and for tool builders who design automated support for task assignment.","2020","2025-04-25 15:32:43","2025-04-25 15:32:43","","","","","","","","","","","","","Univ Rey Juan Carlos; ACM In Cooperat; ACM Special Interest Grp Software Engn; ACM SIGWEB; Irish Software Res Ctr","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most organizations do not have access to sufficient and reliable forms of such data from past projects. As such, the existing SDEE methods suffer from low usage and accuracy. We propose an efficient SDEE method for open source software, which provides accurate and fast effort estimates. The significant contributions of our article are (i) novel SDEE software metrics derived from developer activity information of various software repositories, (ii) an SDEE dataset comprising the SDEE metrics' values derived from approximately 13,000 GitHub repositories from 150 different software categories, and (iii) an effort estimation tool based on SDEE metrics and a software description similarity model. Our software description similarity model is basically a machine learning model trained using the PVA on the software product descriptions of GitHub repositories. Given the software description of a newly envisioned software, our tool yields an effort estimate for developing it. Our method achieves the highest standardized accuracy score of 87.26% (with Cliff's d = 0.88 at 99.999% confidence level) and 42.7% with the automatically transformed linear baseline model.

In this study, OSs in eastern China were investigated to understand their diurnal evolution, source, and volatility using high-resolution mass spectrometry. In polluted days, we identified a total of 5,147 organic molecules, including 1,206 OS molecules. The average molecular weight (m.w.) and carbon chain length of OSs in this study exceeded the commonly recognized range (500 Da). OSs were mostly composed of newly formed low oxidation state compounds as well as aged aliphatic and aromatic ones. The number and abundance of aromatic and aliphatic OSs with low saturation, volatility, O/C-w as well as H/C-w increased greatly with rising PM2.5 concentrations. The daytime photo-oxidation resulted in a large number of high m.w. (HMW, > 500 Da) OSs. OSs with m.w. <500 Da, and many oxygen atoms were newly generated during the nighttime, mainly dominated by liquid-phase oxidation processes. The result of OSs with higher m.w. and lower volatility was due to increased dimerization and oligomerization. During pollution formatting, OSs with small DBE values (between 0 and 6) appeared; meanwhile, the number of highly unsaturated OSs with DBE > 7 (mainly aromatic OSs) increased by about 34%. This study is useful for clarifying the secondary formation and properties of HMW OSs in a polluted environment in China.","2024-05","2025-04-25 15:32:43","2025-04-25 15:32:43","","","","","301","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to ensure the timely delivery of a project, software providers offering this service choose to use Open Sources (OSS) as an alternative. Since OSS consist of an existing framework that can be implemented directly into the application, how far does this affect the complexity of the effort estimation? A number of research papers have outlined the efforts made to refine the complexity of this field. However, to our best knowledge a systematic overview of the research done on Web application development that involves OSS usage does not appear to exist. Hence, the aim of this paper is to conduct a systematic literature review (SLR) of OSS Web application development. For this purpose, 34 papers from a total of 67 papers were identified and studied. The findings of this study indicate that (a) no research has been carried out on the field mentioned; (b) there is no early effort estimation model for Web projects that involve the usage of OSS.

RCF-OSS correlated moderately with RCF accuracy memory and organization, however it seems to be measuring an independent aspect of performance, possibly strategy. Moderate Linear relationships were observed with executive function and memory measures. Considerable age-related variation in strategy formation was observed with significant maturity occurring between the ages of 7 years and 11 years. Surprisingly, older children used fragmented strategies more than the younger age groups. In conclusion, the RCF-OSS is a useful adjunct to traditional accuracy scoring procedures, and the normative data indicates that organizational skills may not consolidate until middle to late adolescence.","2001-02","2025-04-25 15:32:43","2025-04-25 15:32:43","","81-94","","1","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Methods We used open source software to build a data management system and an internet application with a Flex client on a Java application server with a MySQL database backend. The application is hosted on Amazon Elastic Compute Cloud. This solution named Phynx supports data management, Web-based display of electronic patient information, and interactive review of patient-level information in the individual clinical context. This system was applied to a dataset from the UK General Practice Research Database (GPRD). Results Our solution can be setup and customized with limited programming resources, and there is almost no extra cost for software. Access times are short, the displayed information is structured in chronological order and visually attractive, and selected information such as drug exposure can be blinded. External experts can review patient profiles and save evaluations and comments via a common Web browser. Conclusions Phynx provides a flexible and economical solution for patient-level review of electronic medical information from databases considering the individual clinical context. It can therefore make an important contribution to an efficient validation of outcome assessment in drug safety database studies.

In this framework, geographic information, and spatial data and tools such as UAVs (Unmanned Aerial Vehicles) and multispectral optical sensors play a crucial role in the geomatics as support techniques. PA needs software to store and process spatial data and the Free and Open Software System (FOSS) community kept pace with PA's needs: several FOSS software tools have been developed for data gathering, analysis, and restitution. The adoption of FOSS solutions, WebGIS platforms, open databases, and spatial data infrastructure to process and store spatial and nonspatial acquired data helps to share information among different actors with user-friendly solutions. Nevertheless, a comprehensive open-source platform that, besides processing UAV data, allows directly storing, visualising, sharing, and querying the final results and the related information does not exist. Indeed, today, the PA's data elaboration and management with a FOSS approach still require several different software tools. Moreover, although some commercial solutions presented platforms to support management in PA activities, none of these present a complete workflow including data from acquisition phase to processed and stored information. In this scenario, the paper aims to provide UAV and PA users with a FOSS-replicable methodology that can fit farming activities' operational and management needs. Therefore, this work focuses on developing a totally FOSS workflow to visualise, process, analyse, and manage PA data. In detail, a multidisciplinary approach is adopted for creating an operative web-sharing tool able to manage Very High Resolution (VHR) agricultural multispectral-derived information gathered by UAV systems. A vineyard in Northern Italy is used as an example to show the workflow of data generation and the data structure of the web tool. A UAV survey was carried out using a six-band multispectral camera and the data were elaborated through the Structure from Motion (SfM) technique, resulting in 3 cm resolution orthophoto. A supervised classifier identified the phenological stage of under-row weeds and the rows with a 95% overall accuracy. Then, a set of GIS-developed algorithms allowed Individual Tree Detection (ITD) and spectral indices for monitoring the plant-based phytosanitary conditions. A spatial data structure was implemented to gather the data at canopy scale. The last step of the workflow concerned publishing data in an interactive 3D webGIS, allowing users to update the spatial database. The webGIS can be operated from web browsers and desktop GIS. The final result is a shared open platform obtained with nonproprietary software that can store data of different sources and scales.","2021-04","2025-04-25 15:32:44","2025-04-25 15:32:44","","","","4","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Economics often pictures this phenomenon as a case of signalling: individuals engage in the volunteer programming of open-source software (OSS) as a labour-market signal resulting in a wage premium. Yet, this explanation could so far not be empirically tested. This article fills this gap by estimating an upper-bound composite wage premium of voluntary OSS contributions and by separating the potential signalling effect of OSS engagement from other effects. Although some 70% of OSS contributors believe that OSS involvement benefits their careers, we find no actual labour-market premium for OSS engagement. The presence of other motives, such as fun of play or altruism, renders OSS contributions too noisy to function as a signal.","2017","2025-04-25 15:32:44","2025-04-25 15:32:44","","1379-1394","","14","49","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The cornerstone of the proposed approach lies in the introduction of a fictive (or virtual) chemical species, the physical characteristics of which are set to recover some essential properties of combustion and flames. Special emphasis is presently placed on the capability of such a global kinetic scheme to recover three parameters that are recognized as the most influential in terms of turbulence chemistry interactions and turbulent premixed combustion regimes. These parameters are (i) the burnt gases temperature T-b, which settles the value of the thermal expansion factor tau = (T-b - T-u)/T-u, (ii) the propagation velocity delta(0)(L), which is mandatory to reproduce the flame dynamics, and (iii) the laminar premixed flame thickness delta(0)(L). In practice, the thermochemical properties of the fictive species (hereafter denoted by A(Phi)) are set to account for the impact of dissociation effects and partial oxidation of the fuel, i.e., presence of species other than H2O and CO2 in the burnt gases, which allows to recover a satisfactory estimate of T-b. The value of the pre-exponential factor associated to the single-step Arrhenius law is also optimized to reproduce the laminar flame propagation velocity. Finally, the transport characteristics are determined to recover a satisfactory estimate of the thermal flame thickness. The method is general in its principles and quite easy to implement. It is applicable to any couple of fuel and oxidizer. Attention is focused on the application of the method to any stoichiometry but it is also shown that the influence of both pressure and fresh reactants temperature can be recovered. The performance of the resulting optimized single step (OSS) chemistry models are assessed through a direct comparison with detailed chemistry results. Computations of one-dimensional laminar flames are performed with the OSS model using the cantera software for a wide range of pressure levels, fresh reactant temperatures, and equivalence ratios. Obtained results do show that the flame propagation velocity is correctly reproduced for the whole range of parameters, with a maximum value recovered in the vicinity of stoichiometry, a decrease towards rich conditions, and a satisfactory pressure dependence. Burnt gases temperature as well as thermal flame thickness values are also in excellent agreement with those issued from the reference detailed kinetics models. The OSS model is then used to perform direct numerical simulation (DNS) computations of flame kernel growths in both laminar and turbulent conditions. The comparison of obtained OSS results with detailed chemistry computations further confirms the relevance and performance of the proposed methodology. (C) 2018 The Combustion Institute.

Open Source Software (OSS) is recently becoming an important part of software industry. To this end, we conducted an exploratory study on assumptions in OSS development. We extracted and analyzed 9006 posts from the developer mailing list of Hibernate (a popular OSS project), in order to explore (1) assumption expression and (2) classification, (3) the trend of assumptions over time, and (4) related software artifacts of assumptions in OSS development.

The findings are: (1) most of the assumptions are expressed as “Feature Request” and “Solution Proposal”; (2) more than half of the identified assumptions are design assumptions and are made for software design; (3) assumptions exist in the whole OSS development lifecycle; and (4) the major category of related artifacts of assumptions is “Design Document”.","2018","2025-04-25 15:32:44","2025-04-25 15:32:44","","455-464","","","","","","","Asia-Pacific Software Engineering Conference","","","","Special Interest Grp Software Engn, Informat Proc Soc Japan","","","","","","","","","ISSN: 1530-1362","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In OSS architecture, overlay server nodes (OSN) are distributed across the core network architecture of the mobile operator and each node is responsible for both running the game applications and performing the overlay routing. The architecture allows third party game servers that are located outside the core network of the mobile operator to push the execution of delay and bandwidth constrained game components into the core to achieve better quality of service (QoS). When a game consists of multiple mutually exclusive game objects such that each object can be maintained independently, OSS allows per object QoS optimization via selecting the jointly optimal location (i.e. OSN) and overlay routes for each object. This fine-grain optimization benefits most when different objects have different QoS requirements and they are accessed by different users. OSS dynamically adapts to the changes in game and network conditions by switching to better OSN and overlay routes. Our performance analysis on different core network topologies and usage patterns demonstrates that OSS has significant advantages over the alternative peer to peer (P2P), proxy-server, and client-server architectures. The analysis also underlines the individual contributions of object placement and jointly performed overlay route optimization to the performance gain.","2006","2025-04-25 15:32:44","2025-04-25 15:32:44","","","","","","","","","IEEE Global Telecommunications Conference (Globecom)","","","","IEEE Commun Soc (ComSoc)","","","","","","","","","ISSN: 1930-529X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The copyright regime is so restrictive that it turns a normal learning process into a series of potential copyright violations. The Free Software Movement (FSM) represents a substantial community effort to counter this trend. It seeks to supersede the copyright regime by offering the `Copyleft' licensing mode, which facilitates the formation of a cooperative, resource- sharing community. The FSM has been so successful that it has challenged the utilitarian values presumed in copyright law, has fuelled widespread reassessment of copyright law, and has influenced many who engage in various creative activities. Claiming to bear similar values, Creative Commons (CC) provides licensing models for people to waive some rights granted to them. However, CC differs from the FSM in significant ways. Most notably, the flexible CC licensing model weakens the firm philosophical and political ground which binds FSM advocates together. Hence, although CC's rapid growth seems to signal its success, it is questionable whether such success is as enduring as the FSM's, or if it is leading to a different result. While CC champions the author's freedom to decide how to use his or her bundle of property rights granted by copyright law, the FSM advocates the freedom to build and live in an alternative, vital and self- sustaining community. The existence of such an alternative model not only allows these particular participants to be independent from the proprietary world, but also may empower the rest of society to imagine different kinds of relationships between human beings and their creative activities.","2006-12","2025-04-25 15:32:45","2025-04-25 15:32:45","","337-347","","4, SI","4","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to improve the grid qualities, the FOSS GMSH has been used to do three types of grid, unstructured hexahedral mesh, hybrid mesh and structured hexahedral mesh for the simulation of partial cavitation around a plane-convex hydrofoil. Numerical simulations have been carried out by using the FOSS OpenFOAM based on the Zwart cavitation model and the implicit large eddy simulation (ILES).

Specifically, the Structure from Motion (SfM) is an emerging topographic survey technique that addresses the problem of determining the 3D position of image descriptors to estimate three-dimensional structures. Thanks to the potential of SfM algorithm and the development of Unmanned Aerial Vehicles (UAVs) that allow the ondemand acquisition of high-resolution aerial images, it is possible to survey extended areas of the Earth surface and monitor active phenomena through multi-temporal surveys. However, the ability to detect remote and wide areas with a very high-resolution is countered by the need to capture large datasets which can limit the photogrammetric process, due to the need for high-performance hardware. This paper presents a photogrammetric workflow based on Free and Open-Source Software (FOSS), which is able to return different outputs and to manage a large amount of data in reasonable time, through the distribution of the most computationally expensive steps on computing clusters hosted by the ReCaS-Bari data center for scientific research. The results are given in terms of performance evaluations based on different computing configurations of the clusters and setups of the steps of the workflow. The HTC cluster test with a parallel SSH approach involved an important reduction of several hours in the processing time of thousands UAV images, especially compared to classic photogrammetric process on a single workstation with commercial software. A parallel test, aimed to validate the performance of a single sever of the new HPC cluster, involved really good results halving the processing time with respect to the HTC cluster test.","2021-12-25","2025-04-25 15:32:45","2025-04-25 15:32:45","","","","","105","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In their article, the authors make a strong case that “reset thinking” geared towards a more “sustainable” redesign of the global economy promotes extensive state interventionism and cronyism capitalism, and therefore reject the idea of a need for “a funda-mental rethink of existing management theory”. Whereas I do agree with the authors on most points, I am less convinced that “existing management theory” will suffice to address the problem of “reset thinking”. In this article, I demonstrate that the economy-bias of existing theories is a gateway for “reset thinking” geared towards an allegedly necessary re-/socialisation of management and organisation. A research agenda on cronyism must therefore be complemented by one on privilege and hierarchy not only as undesirable side-effects of cronyism, but also as desired outcomes of advocacy for specific minorities or missions. As self-identifications with group interests or calls for missions have become popular in management theory, I conclude that this new appetite for privilege might undermine not only the higher ideals of many management theorists, but also the foundations of modern society.","2023-09","2025-04-25 15:32:45","2025-04-25 15:32:45","","","","3","39","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through professional and occupational competences, individuals are able to deal with the requirements of the phenomenon of globalization. Therefore, many countries have been involved in the creation of quality assurance of educational systems in order to design more flexible curricula, more open to knowledge society. They meet the vast training needs, provide a variety of educational strategies and drive academic mobility and collaborative inter or multidisciplinary projects. In this respect, educational institutions are called to promote methodologies focused on the study of curriculum to diagnose and base the formulation of improvement plans for quality assurance. This project formulated a methodology to examine and determine the level of curricular flexibility. It was based on a prototype of an information system developed with free software that supported management indicators and represented different manifestations of flexibility. On the other hand, the Viable System Model provided the theoretical foundation to specify the study and the organizational diagnosis and to identify the information needs among defined sub-systems, including environment. The prototype of the information system was designed so that academic programs within a higher education institution have the capacity to structure several studies of curriculum flexibility over time in order to establish the necessary comparatives and to be a knowledge-based supply for future curriculum reforms and a basis for quality assurance processes.

Appropriate plaque control is therefore important. Dental floss is one instrument used to control plaque. The influence of guardians is an important factor in whether children use dental floss regularly. However, the use of dental floss among school-age children and the relationship between use and family background has yet to be examined. Aim: In this study, we conducted a questionnaire survey to examine rates of dental floss use and other related factors among elementary school children and their guardians. Methods: Surveys were sent to 298 guardians of children in grades 1-6 at an elementary school in Japan and 283 valid responses were received. Statistical analyses were carried out, with child's use of dental floss as a dependent variable and grade, sex, guardian assistance with child's tooth brushing, frequency of child's dental check-ups, and guardian's use of dental floss as independent variables. Results: The results revealed that 18.4% of children used dental floss compared with 52.7% of guardians, suggesting that the rate of usage among children is much lower than that among guardians. Logistic regression analysis further revealed that guardian's use of dental floss was significantly related to dental floss use among children.

However, there is a noticable vaccum in open-source OSS for a straightforward way for users and administrators to conduct data searches within object storage without fully utilizing the cloud infrastructure. In our research, we present Sherlock, a novel Content-Based Searching (CoBS) framework. Sherlock enhances search capabilities by using extra information from images and documents, incorporating this information into an Elasticsearch-powered database to enable content-driven searches. The framework operates through a two-stage process. First, it classifies the incoming data by type, directing images to an object detection model and processing documents for keyword extraction. Then, Elasticsearch catalogs the extracted data, facilitating searches based on content. The effectiveness of our searches is largely dependent on the precision of these models, which we improve by training them on large-scale datasets: the Microsoft COCO Dataset for multimedia content and the SemEval2017 Dataset for text documents. We further test our system's performance by integrating it with the open-source OSS, OpenStack Swift, and conducting real-world experiments with image uploads to evaluate how our model performs within Swift's object storage environments.","2024","2025-04-25 15:32:45","2025-04-25 15:32:45","","69456-69474","","","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The online fragment-free mass spectra of moxa floss pyrolysis products were obtained within 300-800degree celsius and characterized as hydrocarbons, nitrogenous and oxygenated compounds. The results indicate that pyrolysis temperature plays a leading role in the lowmolecular-weight product distribution, while the storage year has secondary effects. Controlling the pyrolysis temperature in a lower range (<650degree celsius) can effectively reduce the generation of benzene, toluene and other harmful substances. Aromatics could be released from the break of large molecules with aromatic structures and formed from the aromatization of small unstructured compounds at high temperatures. At the temperature lower than 400 degree celsius, short-year samples exhibit a higher intensity of oxygenated compounds. However, with the increase of storage years, nitrogenous heterocyclics such as pyrrole and pyridine are preferably formed at higher temperatures. In addition, increasing the storage year of moxa floss leads the TG curve to exhibit a lower maximum mass loss rate. These results will enrich the understanding of the storage year effect on the beneficial oxygencontaining components generation and the release of harmful components in the moxa floss pyrolysis.","2024-01","2025-04-25 15:32:45","2025-04-25 15:32:45","","","","","177","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The physicochemical properties of MCs are investigated by Raman spectra, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and nitrogen adsorption-desorption isotherms. Results show that MCs derived from moxa floss of different storage years by two facile approaches possess different morphologies: MCs by hydrothermal carbonization (denoted as MC-1, MC-2 and MC-3) exhibit porous nanosheet structures, the highest specific surface area is about 1788.6 m(2) g(-1), and the largest total pore volumes is around 0.8170 cm(3) g(-1), while MCs by direct pyrolysis (denoted as MC-4, MC-5 and MC-6) have basically blocky and rod-like morphologies, the highest specific surface area is about 1628.0 m(2) g(-1), and the largest total pore volume is around 0.7058 cm(3) g(-1). However, despite the different morphologies, all MCs possess a similar hierarchical porous structure, numerous heteroatom groups and good electrical conductivity. Therefore, these low-cost, biomass-derived porous carbons with promising capacitive performance are used for supercapacitors application with high performance, for example, the as-assembled supercapacitor based on MC-5 exhibits a high specific capacitance of 288.3 F g(-1) at 0.25 A g(-1), an excellent rate performance of 243.5 F g(-1) even at 30 A g(-1) with 84.5% capacitance retention of its initial specific capacitance, and an outstanding long-term cycling stability with 98.7% capacitance retention after 10 000 cycles at 5 A g(-1). Furthermore, the maximum energy density for these supercapacitors with an aqueous electrolyte in a two-electrode system is about 10.0 W h kg(-1) at a power density of 70.3 W kg(-1). Therefore, this work opens up a whole new field for the applications of moxa floss and this novel concept of moxa floss use is an extremely promising strategy for developing high-performance carbons with porous structures and heteroatom-doping from renewable sources.","2018","2025-04-25 15:32:45","2025-04-25 15:32:45","","16433-16443","","30","8","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This results in the need for constant adaptation and expansion of OSS/BSS1 used in mobile operator networks. Currently, adaptation and expansion strategies are poorly formalized and validated. In current state-of-the-art approaches, several iterations involving analysts and system architects are necessary, resulting in time and money consuming service development. The workflow design method proposed in this paper fills this gap. It employs a well-defined workflow and analysis model for developing and adapting OSS/BSS. The applicability of this novel approach is confirmed by a prototypically implemented design software tool which has been tested in a telecommunication enterprise. The developed tool provides automation of service planning, computational independent workflow design and its transformation into its realization model.

Many OSS projects are composed of a mix group of firm-paid and volunteer developers, with different motivations, collaboration practices and working styles. As OSS development consists of collaborative works in nature, it is important to know whether these differences have an impact on collaboration between difference types of stakeholders, which lead to an influence in the project outcomes. In this paper, we empirically investigate the firm-paid participation in resolving OSS evolution issues, the stakeholder collaboration and its impact on OSS issue resolution time. The results suggest that though a firm-paid assigned developer resolves much more issues than a volunteer developer does, there is no difference in issue resolution time between them. Besides, the more important factor that influences the issue resolution time comes from the collaboration among stakeholders rather than from individual characteristics.","2011","2025-04-25 15:32:46","2025-04-25 15:32:46","","1+","","","365","","","","IFIP Advances in Information and Communication Technology","","","","CAPES, Minist Educ, Coordinat Improvement Higher Educ Personnel; CNPQ, Minist Sci & Tecnol, Natl Council Sci & Technol Dev; FAPESB, State Bahia Res Agcy; Petrobras","","","","","","","","","ISSN: 1868-4238","","","","","","Hissam, SA; Russo, B; Neto, MGD; Kon, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The development of DCM is accompanied by numerous pathological mechanisms, including oxidative stress and chronic inflammation. Accordingly, the present study aimed to determine the effects of the sirtuin 6 (SIRT6) inhibitor OSS-128167 on DCM using a mouse model of streptozotocin (STZ)-induced diabetes and high glucose (HG)-treated cardiomyocytes. C57BL/6 mice were intraperitoneally injected with STZ for 5 days to simulate the diabetic cardiomyopathy model. Mice with STZ-induced diabetes (STZ-DM1) were orally administered OSS-128167 (20 or 50 mg/kg) through gavage every other day. The expression of SIRT6 in myocardial tissue was detected using western blotting. Tissue staining (hematoxylin and eosin and Masson's trichrome) was used to characterize myocardial structure, TUNEL fluorescent staining was used to detect myocardial apoptosis, and immunohistochemical staining was used to detect the expression of inflammatory factors in myocardial tissue. Dihydroethidium staining and a malondialdehyde (MDA) detection kit were used to detect the oxidative stress levels in myocardial tissues. In vitro, H9c2 cells were pre-incubated with OSS-128167 for 1 h and then stimulated with HG (33 mM) for various durations. Expression levels of fibrosis markers, collagen-1 and transforming growth factor (TGF)-beta, apoptosis-related proteins, Bax, Bcl-2 and cleaved-poly ADP-ribose polymerase, tumor necrosis factor-alpha and the oxidative stress metabolite, 3-nitrotyrosine were analyzed using western blotting and reverse transcription-quantitative PCR. Commercially available kits were used to detect the activity of caspase-3 and the content of MDA in the H9c2 cell line. The corresponding results demonstrated that OSS-128167 aggravated diabetes-induced cardiomyocyte apoptosis and fibrosis in mice. Mechanistically, OSS-128167 was revealed to increase the levels of inflammatory factors and reactive oxygen species (ROS) in vitro and in vivo. In conclusion, OSS-128167 facilitated the inflammatory response and promoted the production of ROS while aggravating DCM development. These findings indicated that SIRT6 may target two closely combined and interacting pathological processes, the inflammatory response and oxidative stress, and may serve as a potentially advantageous therapeutic target.","2021-05","2025-04-25 15:32:46","2025-04-25 15:32:46","","","","5","23","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

When packages are large, they often carry maintainability quality issues. In the literature, there is a lack of empirical evidence on the specific maintainability issues that occur when packages become too large. Our study fills this gap by performing relationship analysis of package size with respect to internal maintainability characteristics (coupling, cohesion, and complexity) using package-level metrics collected from 111 open-source Java projects provided in Qualitas Corpus. Our results show significantly higher main-tainability issues in large packages as indicated by the maintainability metrics. We also report strong relationships of package size with cohesion (represented by the number of connected components in a package) and complexity (measured by the number of internal relationships in a package). Based on these strong associations with package size, we show that these cohesion and complexity metrics can be used to identify large package refactoring opportunities. Furthermore, we also discuss why some maintainability metrics (e.g., coupling metrics) may not be useful for refactoring large packages.Editor's note: Open Science material was validated by the Journal of Systems and Software Open Science Board.(c) 2023 Elsevier Inc.

Many studies point out that most bugs that adversely affect the user's experience across versions of FLOSS projects are longlived bugs. However, proposed approaches that support bug fixing procedures do not consider the real-world lifecycle of a bug, in which bugs are often fixed very fast. This may lead to useless efforts to automate the bug management process. Objective: This study aims to confirm whether the number of long-lived bugs is significantly high in popular open-source projects and to characterize the population of long-lived bugs by considering the attributes of bug reports. We also aim to conduct a comparative study evaluating the prediction accuracy of five well-known machine learning algorithms and text mining techniques in the task of predicting long-lived bugs. Methods: We collected bug reports from six popular open-source projects repositories (Eclipse, Freedesktop, Gnome, GCC, Mozilla, and WineHQ) and used the following machine learning algorithms to predict long-lived bugs: K-Nearest Neighbor, Naive Bayes, Neural Networks, Random Forest, and Support Vector Machines. Results: Our results show that long-lived bugs are relatively frequent (varying from 7.2% to 40.7%) and have unique characteristics, confirming the need to study solutions to support bug fixing management. We found that the Neural Network classifier yielded the best results in comparison to the other algorithms evaluated. Conclusion: Research efforts regarding long-lived bugs are needed and our results demonstrate that it is possible to predict long-lived bugs with a high accuracy (around 70.7%) despite the use of simple prediction algorithms and text mining methods.","2021-04","2025-04-25 15:32:46","2025-04-25 15:32:46","","","","","132","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content. The thermal insulation properties of the nonwovens remained partially stable below 30% relative humidity but substantially deteriorated at higher levels.

Therefore, an efficient approach to evaluate the health status of the open-source project is needed. Unfortunately, although many approaches including metrics have been proposed, they are designed in arbitrary ways. In this paper, a math ematical tool, i.e., factor analysis, is used to build a health evaluation model for OSS projects. As far as we know, this is the first time that factor analysis has been applied to evaluate OSS projects. This model is based on GitHub data and uses the basic indexes that are closely related to the health status of the projects as the input. Then, six new synthetic metrics, namely community activity, project popularity, development activity, completeness, responsiveness and persistence are obtained through factor analysis, which can be used to calculate the overall health score of a project.

Increasingly complex simulations are used to assess similarities and differences between the two models' components. The simulations presented here are forced by ocean currents from a Finite Volume Community Ocean Model (FVCOM) implementation that has excellent skill in representing tidal motion, and with observed wind data that compensates for a coarse vertical ocean model resolution. The comprehensive comparison between GNOME and BLOSOM presented here, should aid modelers in interpreting their results. Beyond many similarities, aspects where both models are distinct are highlighted. Some suggestions for improvement are included, e.g., the inclusion of temporal interpolation of the forcing fields (BLOSOM) or the inclusion of a deflection angle option when parameterizing wind-driven processes (GNOME). Overall, GNOME and BLOSOM perform similarly, and are found to be complementary oil spill models. This paper also sheds light on what drove the historical Point Wells spill, and serves the additional purpose of being a learning resource for those interested in oil spill modeling. The increasingly complex approach used for the comparison is also used, in parallel, to illustrate the approach an oil spill modeler would typically follow when trying to hindcast or forecast an oil spill, including detailed technical information on basic aspects, like choosing a computational time step. We discuss our successful hindcast of the 2003 Point Wells oil spill that, to our knowledge, had remained unexplained. The oil spill models' solutions are compared to the historical Point Wells' oil trajectory, in time and space, as determined from overflight information.

While the choice of wind coefficient we use is unconventional, a simplified analytic model supported by observations, suggests that it is justified under this study's circumstances. We highlight some of the key oceanographic findings as they may relate to other oil spills, and to the regional oceanography of the Salish Sea, including recommendations for future studies.","2018-09","2025-04-25 15:32:46","2025-04-25 15:32:46","","","","3","6","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In her novels she searched for a view of life that would give modern man a sense of purpose, dignity and ethical direction. On reading Eliot's novels with the knowledge of her intellectual development, one must ask how this earnest agnostic could treat traditional religion so sympathetically, why she made the religious experience the subject of her creative work, and what moral truth she found religion to embody. It was the philosophy of the German anthropologist Ludwig Feuerbach, whose book The Essence of Christianity she translated in 1854, in combination with her own earlier experiences as a Christian, which led Eliot to her understanding of the subjective reality embodied in Christianity. `With the ideas of Feuerbach,' Eliot wrote, `I everywhere agree' (Haight, 1954-55, p.153). My paper attempts to show how the influence of Feuerbach achieves complexity and vitality in Eliot's novel The Mill on the Floss and how Eliot establishes her faith in firm and lasting relations, which could be attained through the adjustment of the individual to the community. This adjustment comes as a corollary to the protagonist's realization of the principles that promote love, respect, tolerance and sacrifice for others.","2018","2025-04-25 15:32:46","2025-04-25 15:32:46","","10-18","","3","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community - eZ Publish we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm. In addition, the results of our study highlight the central importance of an integrative IT platform in boundary management activities. (C) 2014 Elsevier Ltd.

There is one degree in Renewable Energy Engineering given at the Gipuzkoa Faculty of Engineering (Eibar). In the last year of their studies, students, can select one subject on Ocean Energy. In this subject, state-of-the-art operation and management techniques are taught to the students. Apart from the transmission of this knowlegde, the focus is practical and is based on hands-on computer real-life exercises, which involves not only intensive programming using a high-level software, but also the spatial representation of results. This is important because currently two major research and development lines can be identified as far as ocean energy is concerned. The first one is the analysis of prototypes that in the future will extensively extract electricity from wave farms. The second one is related to the resource itself, which implies the analysis and characterization of some ocean variables related to the extraction of energy. In many cases, the raw information on some oceanic variables of interest is available from institutions like the ECMWF http://www.ecmwf.int However a very extensive phase of data preprocessing is needed to extract useful information on wave energy potential. This will be an important task for future engineers involved in the spatial planning of oceanic energy facilities and in real-time forecasting and control of electricity obtained at wave farms. For this reason, students need to effectively learn to do all these tasks. R (https://www.cran.r-project.org/) is a freely available software that provides an optimum answer to these combined needs and teaching challenges due to its modular structure. R has a core module and nearly 8000 packages specifically developed for different purposes are also available. Packages like “RNetCDF”, “sp” “rgeos”, “rgdal”, “maps”, “maptools” and “mapdata” have been developed to make R work with full functionalities just like any high-level programming software. Incorporating R into the teaching activities of the subject “Ocean Energy” has represented an important step forward in the education of future engineers while providing them with real-life tools for their future jobs in wave farms.","2016","2025-04-25 15:32:47","2025-04-25 15:32:47","","8696-8702","","","","","","","EDULEARN Proceedings","","","","","","","","","","","","","ISSN: 2340-1117","","","","","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thus, an outstanding challenge in the Geosciences is to define workflows using free alternatives for Computed Tomography (CT) data processing, promoting data sharing, reproducibility, and the development of specific extensions. We present CroSSED, a processing sequence for 3D reconstructions of CT data, using 3DSlicer, a popular application in medical imaging. Its usefulness is exemplified in the study of burrows that have low-density contrast with respect to the host sediment. For geoscientists who have access to CT data and wish to reconstruct 3D structures, this method offers a wide range of possibilities and contributes to open-science and applied CT studies.","2020-08-14","2025-04-25 15:32:47","2025-04-25 15:32:47","","","","1","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These ideas are implemented as an open source module, SCRIBO, built on top of Olena, a generic and efficient image processing platform. Our solution features services such as preprocessing filters, text detection, page segmentation and document reconstruction (as XML, PDF or HTML documents).

This software is composed by a desktop user-friendly interface and an Abstract Programming Interface library. The former was created to simplify the configuration of the different options of the MDs, whereas the library was designed to allow its easy integration to other software for chemoinformatics applications. This program provides functionalities for data cleaning tasks and for batch processing of the molecular indices. In addition, it offers parallel calculation of the MDs through the use of all available processors in current computers. The studies of complexity of the main algorithms demonstrate that these were efficiently implemented with respect to their trivial implementation. Lastly, the performance tests reveal that this software has a suitable behavior when the amount of processors is increased. Therefore, the QuBiLS-MIDAS software constitutes a useful application for the computation of the molecular indices based on N-linear algebraic maps and it can be used freely to perform chemoinformatics studies.

The Digital Video Broadcast Return Channel Satellite (DVB-RCS) NetOps vision for remote management and monitoring aims to provide visibility and Situational Awareness to required communities of interest as well as the ability to view and configure all the operational layers DVB-RCS, including the devices and technology, operations and management, and missions and objectives. An effective management and monitoring solution for DVB-RCS must provide the capability to centrally manage and monitor the system, interoperate between SATCOM and terrestrial networks, consolidate technology, standardize processes, and be proactive rather than reactive. The DISN OSS is DISA's enterprise-wide Service Oriented Architecture for information sharing, management, and monitoring capabilities, based on the Telecommunications Management Network industry standards. The DISN OSS puts the information into the hands of the operators and system managers while making the processes, tools, and technology transparent to the consumer. This paper examines how DVB-RCS implemented the NetOps Portal as an immediate and interim solution to provide Situational Awareness to CENTCOM, as well as how leveraging the DISN OSS can help DVB-RCS achieve assured system and network availability, assured information protection, and assured information delivery in support of high-bandwidth, two-way services for the tactical Warfighter.","2009","2025-04-25 15:32:47","2025-04-25 15:32:47","","2378+","","","","","","","IEEE Military Communications Conference","","","","IEEE","","","","","","","","","ISSN: 2155-7578","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals' early career stages profoundly impact their long-term career success. However, newcomers' early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers' dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers' contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers' early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers' technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers' early careers and hence shed light on future research in this direction.","2023-02-01","2025-04-25 15:32:47","2025-04-25 15:32:47","","529-548","","2","49","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Cotton candy floss is a longstanding popular technique to prepare cotton like fibres in food applications. This study investigated the potential feasibility of using candy floss spinning (CFS) technique to generate new PLA-clay bionanocomposites with exfoliated morphology. The dispersion of nanoclay in PLA-clay bionanocomposites prepared by internal mixing, with and without candy floss spinning, as a masterbatch (having 20%wt nanoclay) and then diluted in twin screw extruder to different percentage of nanoclay loadings (1%, 2% and 4%, w/w), were compared in terms of their structures and properties. They were subjected to several tests: tensile and flexural tests, differential scanning calorimetry (DSC), simultaneous thermal analysis (STA), dynamic mechanical analysis (DMA), gel permeation chromatography (GPC), X-ray diffraction (XRD) study, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Overall, mechanical, and thermal properties of the bionanocomposites were improved in comparison to the neat PLA. Furthermore, XRD study exposed that bionanocomposites pre -pared by the CFS technique showed the disappearance of d001 basal peak, confirming generation of exfoliated microstructures, whereas the samples prepared solely by the internal mixing technique showed intercalated structure. Additionally, PLA-clay bionanocomposites prepared by the candy floss spinning technique exhibited prominent enhancement of mechanical as well as thermal properties compared to the ones prepared solely by internal mixing. These bionanocomposites possess great potential to find application as food packaging material.","2023-12","2025-04-25 15:32:47","2025-04-25 15:32:47","","","","","40","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our results show that successful FLOSS teams demonstrate a truly global distribution of members, who perform different types of work so as to achieve consistent round-the-clock development, without any apparent ill effects on team productivity and the quality of the resulting outcomes. Cooperation between team members is abundant, especially at more complex work items, and does not seem to be affected by distance; only mentoring relationships appear in some cases to be easier to cultivate between individuals living closer together.

These active sensors, namely synthetic aperture radar (SAR) satellites, provide systematic datasets for mapping land movements triggered from earthquakes, landslides, and so on. Copernicus, the European program for monitoring the environment, provides continuous radar datasets through the Sentinel-1 mission with an almost worldwide coverage. This paper aims to demonstrate how the use of open-access and freely distributed datasets such as those under the Copernicus umbrella, along with the exploitation of open-source radar processing software, namely the sentinel applications platform (SNAP) and SNAPHU tools, provided respectively by the European Space Agency (ESA) and the University of Stanford, can be used to extract an SAR interferogram in the wider area of Paphos, located in the western part of Cyprus.

However, as argued in this paper, the process of this vertical disintegration may be affected by high investments to software interface implementation and maintenance. Should the required efforts be large, the threshold for entering the market increases, thereby hampering the vertical disintegration process. This study examines the impact of the interface implementation efforts on the vertical market evolution in the case of the so-called operations support systems and business support systems (OSS/BSS) software, which are employed by the telecom operators in order to support their daily operations. The efforts are compared for two prototypical software vendors serving incumbent operators and new operators respectively. Total efforts are an order of magnitude larger in the former case. Furthermore, even if only latest network protocols are taken into account, the efforts are significantly larger in the former case, therefore requiring several times greater number of employees to implement them. Therefore, a conclusion is made that the OSS/BSS market is likely to polarize into the vertical submarket of large software vendors serving incumbent operators, and the submarket of small vendors serving young operators. The latter submarket, due to the lower entry threshold for new vendors is more likely to be vertically disintegrated.","2008","2025-04-25 15:32:48","2025-04-25 15:32:48","","80+","","","","","","","","","","","Inst Syst & Technol Informat, Control & Commun; Workflow Management Coalit, Proc Thought Leadership; IICREST","","","","","","","","","","","","","","","Cordeiro, J; Shishkov, B; Ranchordas, A; Helfert, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, they founded the Coordination of Information (COI) and subsequently, the Office of Strategic Services - OSS), naming General William Donovan as head of both. Right from the establishment of OSS, Donovan wanted to expand its operations to North African and Mediterranean battlefields in order for the American intelligence service to be able to direct special operations against the Axis Powers in Yugoslavia from there. The setting up of the bases required a considerable amount of effort and negotiation with the British secret services, as they were used to defending their own interests and leading intelligence position in the Balkans and would not permit the OSS to operate independently in Yugoslavia. Donovan thus established bases in Cairo and Bari, with a Yugoslav section operating within each. The principal tasks of the two sections were to train the personnel to be sent to Yugoslavia, to gather intelligence about Yugoslavia, organise assistance and support for Yugoslav resistance movements and compile intelligence obtained by the OSS from its missions from the occupied Yugoslav territory. Aided initially by the government in exile and later on by Partisan representatives in southern Italy, the Yugoslav sections trained numerous Yugoslays many of who were Slovenes and sent them back to Yugoslavia. These worked as wireless operators, cryptographers and interpreters mostly between Slovene and Croatian Partisans. Some Slovenes, American Slovenes in particular, carried out the functions of mission chiefs or instructors in the Yugoslav sections of the OSS. Although collaborators with the American intelligence service made important contribution to the common struggle against the Axis Powers, they were branded by the Partisan leadership towards the end of the war and after it for having worked with the Americans. Following the Tehran Conference in December 1943, the supply of aid for the resistance movements was directed to support the Partisan movement. Towards the end of the war and with the growth of the National Liberation Movement (NOG) in Yugoslavia, the role of the Yugoslav section gradually diminished It can be concluded that the activities of the Yugoslav sections in Cairo and Bari significantly influenced the development of resistance movements in Yugoslavia and Slovenia, both in terms of organising aid as well as training and sending the American missions to Yugoslavia.","2012","2025-04-25 15:32:48","2025-04-25 15:32:48","","809-826","","4","20","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Her men cultivate and punish their women when they resist naturalizing. Without denigrating the intelligence of women, von Arnim shows their unwitting complicity in their subjection. In The Pastor's Wife (1914) and in Vera (1921), the highly literate women have read the wrong books or missed the unfriendly truths about relationships in those they have read. The husbands and lovers make shallow use of philosophical and scientific reasoning to justify their control and enforce female uniformity deemed natural'. Darwin is misappropriated by the tyrannical Wemyss: evolutionary theories support his imperious dismissal of Lucy's aunt and friends. Wemyss's most monstrous actions suggest an atavistic patriarchal dominance like the hereditary reversion theorized by Samuel Butler as unconscious memory. Wemyss brings up the issue of England's inheritance, and a disturbing vision dawns as the philistine and self-appointed natural man subdues Lucy. Daphne du Maurier's Rebecca (1938) follows Vera's plot, but it does not interrogate naturalness in the same way. Entrapped in her husband's vision of a natural woman, the narrator registers Rebecca's wild transgressiveness as more powerful and universal than her own tamed naturalness.","2017","2025-04-25 15:32:48","2025-04-25 15:32:48","","115-129","","1-2, SI","28","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The RSS was scoured firstly in strongly alkaline electrolyzed water (SAEW, pH >= 11.5) consisting mainly of hydroxyl ions by boiling for 30 min and then treated by the traditional scouring procedure (without alkaline compounds), resulting in refined silk floss. The recycled SAEW containing sericin was separated by ultrafiltration into a retentate with a range of high molecular mass values accounting for 10% (w/w) of the cocoon shell and the filtrate was separated by nanofiltration into a purified H2O filtrate and a retentate containing oligopeptides and free amino acids, which can be used directly as food additives or in biological growth media. The ultrafiltration retentate was hydrolyzed by papain under three different conditions into three groups of sericin peptides with high, middle or low molecular mass. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and gel permeation high-performance liquid chromatography (GP-HPLC) showed the molecular mass of these sericin peptides was in the range 0.2-60, 0.2 -30 and 0.2-15 kDa. These clean products have a variety of applications, including coating materials for surface modification, cell culture media and food additives. The procedure described here could be applied to the manufacture of silk floss quilts and the process of refining raw silk, which results in three clean products of the silk protein fibroin (i.e. stripped of sericin) and reduces environmental pollution from scouring waste containing sericin.

The utilization of the platform is facilitated by a collection of predefined input setups and quick visualization routines. The accuracy of a VCM, created and optimized by the platform, was estimated by comparison with a commercial software. The results demonstrate no significant deviation between the models in the electric potential distribution. A qualitative estimation of different physics for the VCM shows an agreement with previous computational studies. The proposed computational platform is suitable for an accurate estimation of electric fields during DBS in scientific modeling studies. In future, we intend to acquire SDA and EMA approval.

Preliminary method for the A50 road link (Eindhoven-Oss, The Netherlands)","ECOLOGICAL ENGINEERING","","0925-8574","10.1016/S0925-8574(96)00024-9","","After years of efforts to avoid or reduce the impact of infrastructure projects on nature, the principle of ecological compensation has been incorporated in Dutch governmental policy. Ecological compensation aims to recover those ecological functions and natural values that still remain affected after maximum effort has been made to reduce the impact of the intervention (mitigation). The accepted aim of current policy is thus no-net-loss of area and quality by means of mitigative and compensatory measures. As part sf the planning process for construction of a stretch of road in The Netherlands, viz,, the A50 road link in the province of North Brabant, a Nature Compensation Plan (NCP) was required to be drawn up. This work has recently been completed by the Regional Directorate of Public Works and Water Management, the initiator of the intervention. The NCP, initially presented as a Draft Plan, was drawn up by the Regional Directorate using a preliminary method designed by the Centre of Environmental Science of Leiden University for deriving compensatory measures. After an opportunity for public comment, the Draft Plan was revised to form a Final NCP. This article describes, firstly, the preliminary method for deriving ecological compensatory measures. The method starts by quantifying the effects of habitat loss, habitat disturbance (by changes in noise emissions, in the water table and in outdoor recreational patterns), barrier action and fauna casualties. Following mitigation of impacts on nature, compensation for non-mitigable effects focuses successively on area size, derived from the impact on breeding birds, and on area quality, derived from the habitat requirements of the vegetation and fauna groups affected by the road. Guidelines for identifying appropriate locations for compensation are also formulated. Secondly, the compensation method is applied to calculate the mitigative and compensatory measures for the A50 trajectory between Eindhoven and Oss. Thirdly, two comparisons are made: the Draft NCP is compared with the results of the preliminary method, and the Draft and the Final NCP are compared with one another in order to identify the role of the interest groups that played a major role in commenting on the Draft Plan. Finally, realization of the compensatory measures and development of the preliminary method itself are discussed. On the basis of the experience with the A50 case study, a more robust compensation method for road projects is to be developed.","1996-12","2025-04-25 15:32:48","2025-04-25 15:32:48","","327-349","","4","7","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A Large-Scale Empirical Measurement Study on FOSS Vulnerability Lifetimes","PROCEEDINGS OF THE 31ST USENIX SECURITY SYMPOSIUM","978-1-939133-31-1","","","","How long do vulnerabilities live in the repositories of large, evolving projects? Although the question has been identified as an interesting problem by the software community in online forums, it has not been investigated yet in adequate depth and scale, since the process of identifying the exact point in time when a vulnerability was introduced is particularly cumbersome. In this paper, we provide an automatic approach for accurately estimating how long vulnerabilities remain in the code (their lifetimes). Our method relies on the observation that while it is difficult to pinpoint the exact point of introduction for one vulnerability, it is possible to accurately estimate the average lifetime of a large enough sample of vulnerabilities, via a heuristic approach. With our approach, we perform the first large-scale measurement of Free and Open Source Software vulnerability lifetimes, going beyond approaches estimating lower bounds prevalent in previous research. We find that the average lifetime of a vulnerability is around 4 years, varying significantly between projects (similar to 2 years for Chromium, similar to 7 years for OpenSSL). The distribution of lifetimes can be approximately described by an exponential distribution. There are no statistically significant differences between the lifetimes of different vulnerability types when considering specific projects. Vulnerabilities are getting older, as the average lifetime of fixed vulnerabilities in a given year increases over time, influenced by the overall increase of code age. However, they live less than non-vulnerable code, with an increasing spread over time for some projects, suggesting a notion of maturity that can be considered an indicator of quality. While the introduction of fuzzers does not significantly reduce the lifetimes of memory-related vulnerabilities, further research is needed to better understand and quantify the impact of fuzzers and other tools on vulnerability lifetimes and on the security of codebases.","2022","2025-04-25 15:32:48","2025-04-25 15:32:48","","359-376","","","","","","","","","","","USENIX Assoc; Meta; Google; NSF; Baidu; Chainlink; IBM; Intel Secur; Red Canary; Mercari; Paloalto; Technol Innovat Inst","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within wide limits topography and soil type, texture, and fertility seemed to be of minor importance, although milkweed appeared to grow best on well drained lighter soils of average to high fertility and was never found on poorly drained or highly acid soils. Milkweed appeared to find its most favorable environment on recently abandoned row-crop land and on recently cut-over stump land in situations where a sod of quackgrass or bluegrass had not been established. In Emmet County, probably the most densely infested county in the U.

Six wideband grating modules combine to cover the full band at R=300, each couples a long slit with 60-190 beams on the sky. OSS will have a total of 120,000 background-limited detector pixels in the six 2-D arrays which provide spatial and spectral coverage.

Further, the reliability of flood loss and risk estimates is fairly unknown, since flood loss models are scarcely validated. In the aftermath of flooding in August 2002 large data sets of flood losses were collected at affected properties in Germany. These data were used to derive multi-factorial loss models. This paper presents FLEMOps - the Flood Loss Estimation Model for the private sector, which estimates direct monetary flood losses of residential buildings and household contents considering water level, building type and building quality. In an additional model stage (FLEMOps+), the effects of private precautionary measures as well as of the contamination of the floodwater can be quantified. Together with census data and land use information the model is adapted for applications on the meso-scale. Further, different data sets of repair costs for single buildings and in whole municipalities were used to validate loss estimates on the micro- as well as on the meso-scale. First results show that the model FLEMOps+ outperforms simple stage-damage-functions.","2008","2025-04-25 15:32:49","2025-04-25 15:32:49","","315+","","","118","","","","WIT Transactions on Ecology and the Environment","","","","Univ Wolverhampton; Wessex Inst Technol; WIT Transact Ecol & Environm; Royal Inst Chartered Surveyors; Chartered Inst Loss Adjusters","","","","","","","","","ISSN: 1743-3541","","","","","","Proverbs, D; Brebbia, CA; PenningRowsell, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the mathematical solution of the 3D forward intersection with the analytical definition of spatial lines, resolved by the Minimum Distances Method, is still not widespread in the academic and professional environment. This mathematical modeling determines the 3D coordinates of a point located in the middle of the minimum distance between two or more spatial lines, which spatially “intersect” towards the observation point. This solution is more accurate than others presented in the literature because it simultaneously solves the problem of 3D determination of a point by the method of least squares, in addition to providing an estimate of the coordinate precision, which are inherent to the adjustment. This work, therefore, has the objective of explaining the Minimum Distances Method for the spatial intersection of targeted measurements with a Total Station from two or more known observation points for the 3D determination of inaccessible points located in corners of buildings. For the analysis of the method, a Python tool was developed for QGIS that calculates the 3D coordinates and generates the adjustment processing report, being applied with real observations of the Geodetic survey of the SUDENE building, in Recife-PE.

It allows the creation of live loads, and these are used in calculating the envelope of internal forces in bridge beams. Despite this, a significant number of projects, dissertations and theses in the area of bridges, especially in graduate courses, still do not use it in the analysis of life loads in bridge beams. In this sense, this project aims to encourage the use of Ftool to carry out structural analysis in beams of bridge beams, whether in determining the respective lines of influence or internal efforts; so that graduate students and researchers start to use it in their respective projects. Four numerical examples are developed and each one uses paid software, SAP2000, Ansys or GAP-GEL v1, and the results are compared with Ftool. In all examples, the variations in the results are less than 9%, in the worst case, but in most of them, this variation is less than 3%. These differences can be considered as acceptable, since, later, different coefficients are applied. Finally, the Ftool proved to be effective and robust, with reliable results and, therefore, recommended for the determination of the different internal and TTL efforts in the beams, due to different live loads acting on bridge decks composed of two, three, seven and eight beams.

However, it is not exactly sure how FLOSS developers think about bugs to be removed preferentially. Without a full understanding of FLOSS developers' perceptions of bug finding and fixing, researchers' efforts might remain far away from FLOSS developers' needs. In this study, we interview 322 notable GitHub developers about high impact bugs to understand FLOSS developers' needs for bug finding and fixing, and we manually inspect and classify developers' answers (bugs) by symptoms and root causes of bugs. As a result, we show that security and breakage bugs are highly crucial for FLOSS developers. We also identify what kinds of high impact bugs should be studied newly by the SE community to help FLOSS developers.","2019","2025-04-25 15:32:49","2025-04-25 15:32:49","","44-57","","","556","","","","IFIP Advances in Information and Communication Technology","","","","IFIP WG 2 13","","","","","","","","","ISSN: 1868-4238","","","","","","Bordeleau, F; Sillitti, A; Meirelles, P; Lenarduzzi, V","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A Preliminary Study on the Effect of Social Proof and Legitimization of Paltry Contributions in Donations to OSS","2019 IEEE 26TH INTERNATIONAL CONFERENCE ON SOFTWARE ANALYSIS, EVOLUTION AND REENGINEERING (SANER)","978-1-72810-591-8","","10.1109/saner.2019.8667974","","Open source communities have contributed widely to modern software development. The number of open source software (OSS) has increased rapidly in the past two decades. Most open source foundations (such as Eclipse, Mozilla and Apache) operate as non-profit; those foundations usually seek donations from users/developers to financially support their activities. Without such support, some projects might discontinue to develop, or even disappear. However, contributions to those foundations are usually solicited in a very simple and modest way, with no special promotions or attractions for such contributions. The aim of this study is to promote new strategies that can help to increase donations to OSS projects. We analyzed how existing donation pages are structured. We then introduce behavioral economics and psychological theories that have been used in other disciplines to promote donations in OSS. In particular, we used the social proof theory, i.e., where people tend to consider the actions of others in an attempt to reflect correct behavior when they choose their own actions, and legitimization of paltry contributions strategy i.e., using specific phrases such as “even a very small amount will help” to encourage donations. In this study, we conducted an experiment with University students to examine if those theories are effective in encouraging donations to OSS. Our initial results indicate that the two strategies were indeed effective in promoting donations, and showed that users were more open for donation compared to traditional methods. This is only a preliminary analysis - we aim to include more users in the future for a more comprehensive analysis. We anticipate that such techniques might help OSS projects to secure more donations in the future.","2019","2025-04-25 15:32:49","2025-04-25 15:32:49","","609-613","","","","","","","","","","","IEEE; IEEE Comp Soc; IEEE Comp Soc, Tech Council Software Engn; Zhejiang Univ","","","","","","","","","","","","","","","Wang, X; Lo, D; Shihab, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Intimate contact between newly formed bone and the particles of the graft was present. No overt signs of resorption of the graft particles were visible. Histomorphometric analysis revealed 63% of implant-bone contact in the zone of pre-existing bone, and 73% in the grafted zone. The area density of bone amounted to 27% in the non-grafted as compared to 28% in the grafted area.

In this paper, a microRNA-activated scaffold constituted of microRNA21 nanoparticles combined with porous Bio-Oss particles was designed for the use of accelerating the early stage healing of the alveolar bone. It was noteworthy that the regeneration of alveolar bone was rapidly promoted to be shortened from the ordinary 3 months to 2 weeks. The nanoparticles designed by us according to the oral environment could protect microRNA from various enzymes and electrolytes attack, leading to a steady, continuous, and efficient delivery of gene. With the aid of porous Bio-Oss, microRNA-21 released in situ and its effects on highly reducing the recovery time and improving the quality of newly formed bone at the alveolar site were confirmed for the first time. Great potential could be seen for the microRNA-mediated biofunctionalized scaffold on the future dental application.","2020-12-01","2025-04-25 15:32:50","2025-04-25 15:32:50","","","","","401","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The novel's return to an earlier stage in the development of capital places the 1830s of the story in dialogue with the 1860s of its narration, while inviting readers to compare the values of this earlier period to those of their own. Considering this comparative structure in relation to nineteenth-century ethnography and its interlocutors-including Auguste Comte, Ludwig Feuerbach, and Karl Marx-I read Edward Tulliver's primitive materialism and the Dodson sisters' fetishism as both humorous reactions and more earnest forms of resistance to this increasing abstraction. Eliot ultimately turns toward the figurative possibilities of sublimation as a way to bridge the concrete and the abstract, the particular and the general, will and affect, self and other. Sublimation-not liquidation-therefore serves as the more apt metaphor for sympathy in the novel.","2017-12","2025-04-25 15:32:50","2025-04-25 15:32:50","","338-373","","3","72","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Methods Five beagle dogs were used. Four premolars in the mandible (P-3(3), P-4(4)) were hemi-sected, the distal roots were removed and the fresh extraction socket filled with Bio-Oss (R) Collagen. The mucosa was mobilized and the extraction site was closed with interrupted sutures. The tooth extraction and grafting procedures were scheduled in such a way that biopsies representing 1 and 3 days, as well as 1, 2 and 4 weeks of healing could be obtained. The dogs were euthanized and perfused with a fixative. Each experimental site, including the distal socket area, was dissected. The sites were decalcified in EDTA, and serial sections representing the central part of the socket were prepared in the mesio-distal plane and parallel with the long axis of the extraction socket. Sections were stained in hematoxylin and eosin and were used for the overall characteristics of the tissues in the extraction socket. In specimens representing 1, 2 and 4 weeks of healing the various tissue elements were assessed using a morphometric point counting procedure. Tissue elements such as cells, fibers, vessels, leukocytes and mineralized bone were determined. In deparaffinized sections structures and cells positive for tartrate-resistant acid phosphatase activity (TRAP), alkaline phosphatase and osteopontin were identified. Results The biomaterial was first trapped in the fibrin network of the coagulum. Neutrophilic leukocytes [polymorphonuclear (PMN) cells] migrated to the surface of the foreign particles. In a second phase the PMN cells were replaced by multinuclear TRAP-positive cells (osteoclasts). The osteoclasts apparently removed material from the surface of the xenogeneic graft. When after 1-2 weeks the osteoclasts disappeared from the Bio-Oss (R) granules they were followed by osteoblasts that laid down bone mineral in the collagen bundles of the provisional matrix. In this third phase the Bio-Oss (R) particles became osseointegrated. Conclusions It was demonstrated that the incorporation of Bio-Oss (R) in the tissue that formed in an extraction wound involved a series of different processes.

The first one was aimed at defining and identifying Collaborative Economy practices linked to Andalusia's public universities. The second study searched for entrepreneurship sharing initiatives in the region. The results led to the following question about the nature of the Collaborative Economy: Is it possible to define these practices as postcapitalist initiatives and do they promote a fairer and more equalitarian society or do they respond to capital forces and simply aim to continue extracting and privatizing value which is socially generated? This article analyses a specific set of initiatives identified in Andalusia, those based on open source software and digital production.

While many laboratories have software that is used internally, reproducibility requires the availability of open-source software. Therefore, we here introduce the `SleepCycles' package for R, an open-source software package that identifies sleep cycles and their respective (non-) rapid eye movement ([N]REM) periods from sleep staging data. Additionally, each (N)REM period is subdivided into parts of equal duration (percentiles), which may be useful for further fine-grained analyses. The detection criteria used in the package are, with some adaptations, largely based on criteria originally proposed by Feinberg and Floyd (1979). The latest version of the package can be downloaded from the Comprehensive R Archives Network (CRAN). The package `SleepCycles' for R allows to identify sleep cycles and their respective NREM and REM periods from sleep staging results. Besides the cycle detection, NREM and REM periods are also split into parts of equal duration (percentiles) thereby allowing for a better temporal resolution across the night and comparisons of sleep cycles with different durations amongst different night recordings.

Bone tissue regeneration remains one of the most important issues of maxillofacial surgery. Restoration of the native structure of bone after osteoplasty is directly related to the process of revascularization, because the growing of blood vessels into the graft is a precondition for transport of osteogenic cells, growth factors necessary for further osteogenesis. Objectives. To determine the peculiarities of bone tissue regeneration after osteoplasty with BioOss (R) and compare it with autological bone graft. Material and Methods. Experimental study was conducted on 60 white rats (males, aged 6- 8 month, weight 270- 380 g). The area of dorsal surface of the shinbone was used for implantation. After opening access to the bone surface, one 2 mm-diameter defect was formed on each shinbone. One of those bone defects was filled with osteoplastic material and the opposite was healing under a blood clot. After that the wound in soft tissues was closed in layer by layer. The osteocalcin level in blood serum was determined by ELISA employing N-MID Osteocalcin (R) ELISA (IDS) test system(enzyme immunological test for the quantitative measurement of osteocalcin). The peculiarities of revascularization were studied by histologic method. Histologic specimen were stained using Schmorl technique (thionine with phenol trinitrate) and natural hematoxylin-eosin. Results. Mean values of osteocalcin concentration after BioOss implantation ranged from 2 +/- 0.06 ng/mL to 3.65 +/- 0.09 ng/mL; after autological bone graft transplant - from 1.88 +/- 0.09 ng/mLto 2.2 +/- 0.09 ng/mL. In the case of Bio-Oss use, the most active revascularization processes and the highest level of osteocalcin were registered on day 60.

OSS is an M-class mission to explore the Neptune system almost half a century after the flyby of the Voyager 2 spacecraft. Several discoveries were made by Voyager 2, including the Great Dark Spot (which has now disappeared) and Triton's geysers. Voyager 2 revealed the dynamics of Neptune's atmosphere and found four rings and evidence of ring arcs above Neptune. Benefiting from a greatly improved instrumentation, a mission as OSS would result in a striking advance in the study of the farthest planet of the solar system. Furthermore, OSS would provide a unique opportunity to visit a selected Kuiper Belt object subsequent to the passage of the Neptunian system. OSS would help consolidate the hypothesis of the origin of Triton as a Kuiper Belt object captured by Neptune, and to improve our knowledge on the formation of the solar system. The OSS probe would carry instruments allowing precise tracking of the spacecraft during the cruise. It would facilitate the best possible tests of the laws of gravity in deep space. These objectives are important for fundamental physics, as they test General Relativity, our current theoretical description of gravitation, but also for cosmology, astrophysics and planetary science, as General Relativity is used as a tool in all these domains. In particular, the models of solar system formation uses General Relativity to describe the crucial role of gravity. OSS is proposed as an international cooperation between ESA and NASA, giving the capability for ESA to launch an M-class mission towards the farthest planet of the solar system, and to a Kuiper Belt object. The proposed mission profile would allow to deliver a 500 kg class spacecraft. The design of the probe is mainly constrained by the deep space gravity test in order to minimize the perturbation of the accelerometer measurement.","2012-10","2025-04-25 15:32:50","2025-04-25 15:32:50","","203-242","","2, SI","34","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although social networks constructed in online environment can reduce such possibilities, it is not without limitations. One possible mechanism for learning and knowledge flow is direct watching and observation. This study investigates the impact of co-membership taking into account the alternative mechanism of watching under the setting of OSS development at GitHub. It finds that both co-membership and watching contribute positively to OSS success, and thus shows the co-existence of both experiential learning and vicarious learning for OSS development. Moreover, it finds the impact of co-membership is much stronger than watching. While the impact of co-membership may be biased in prior literature, this study confirms that co-membership is indeed an effective mechanism for constructing online social networks for knowledge flow.","2018","2025-04-25 15:32:50","2025-04-25 15:32:50","","4252-4260","","","","","","","","","","","Pacific Res Inst Informat Syst & Management; Shidler Coll Business; IBM; Bizgenics Fdn; Arizona Eller; AIS; Baylor Business Informat Syst; Int Soc Serv Innovat; St Johns Univ, Coll Profess Studies; Syracuse Univ, Sch Informat Stud","","","","","","","","","","","","","","","Bui, TX","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here we present a wide range of free and open source software tools that are used in biomedical sequencing workflows around the world today. Since its introduction in 2011 the variant call format (VCF) has been widely adopted for processing DNA and RNA variants in practically all population studies-as well as in somatic and germline mutation studies. The VCF format can represent single nucleotide variants, multi-nucleotide variants, insertions and deletions, and simple structural variants called and anchored against a reference genome.Here we present a spectrum of over 125 useful, complimentary free and open source software tools and libraries, we wrote and made available through the multiple vcflib, bio-vcf, cyvcf2, hts-nim and slivar projects. These tools are applied for comparison, filtering, normalisation, smoothing and annotation of VCF, as well as output of statistics, visualisation, and transformations of files variants. These tools run everyday in critical biomedical pipelines and countless shell scripts. Our tools are part of the wider bioinformatics ecosystem and we highlight best practices.We shortly discuss the design of VCF, lessons learnt, and how we can address more complex variation through pangenome graph formats, variation that can not easily be represented by the VCF format.","2022-05","2025-04-25 15:32:50","2025-04-25 15:32:50","","","","5","18","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to effectively promote the growth of online secondhand markets, this paper designs and validates a scale to assess customer perception of the service quality of secondhand products purchased via online platforms. Complementarily, the paper assesses how each of the different dimensions that configure the scale contributes to explaining the fulfillment of customers' expectations. The scale is defined by 23 items and is arranged in 5 dimensions from the literature on online commerce as well as on the sharing economy. A sample of 200 questionnaires is used for exploratory factor analysis. A second sample of 507 users is used for confirmatory factor analysis. The quality perceived by online customers of secondhand products depends on the quality of the interactions that they have with the website, with the vendor, and with the product. The dimension that contributes the most to customer fulfillment of expectations is product quality. Findings identify the items that contribute the most to quality perception and fulfillment of expectations, facilitating the development of more effective strategies for platform owners and vendors who want to attract and retain customers of secondhand products. Complementarily, these findings are useful to businesses and governments that want to promote a more sustainable economy by reducing consumption of new products and promoting reutilization of existing ones.","2020-11","2025-04-25 15:32:50","2025-04-25 15:32:50","","","","21","12","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to mitigate the impact of natural hazards on European economies and societies, improved risk assessment, and management needs to be pursued. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models have become an important part of flood risk management (FRM). In this context, free and open-source (FOSS) geospatial models provide better and more complete information to stakeholders regarding their compliance with the Flood Directive (2007/60/EC) for effective and collaborative FRM. A geospatial model is an essential tool to address the European challenge for comprehensive and sustainable FRM because it allows for the use of integrated social and economic quantitative risk outcomes in a spatio-temporal domain. Moreover, a FOSS model can support governance processes using an interactive, transparent and collaborative approach, providing a meaningful experience that both promotes learning and generates knowledge through a process of guided discovery regarding flood risk management. This article aims to organize the available knowledge and characteristics of the methods available to give operational recommendations and principles that can support authorities, local entities, and the stakeholders involved in decision-making with regard to flood risk management in their compliance with the Floods Directive (2007/60/EC).","2015-12","2025-04-25 15:32:50","2025-04-25 15:32:50","","2704-2727","","4","4","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considering that traditional salinity reconstruction methods often suffer from various factors such as additional constraints, priori physical assumptions and large of specific regression coefficients, a generative adversarial networks (GANs) based deep learning (DL) framework is proposed to directly construct a near real-time, high-resolution daily three-dimensional ocean subsurface salinity (3D OSS) dataset from a data driven perspective in this study. Four models with different structural combinations are designed in the China's marginal seas. Experimental results demonstrate that the models can successfully reconstruct the high-precision and high-resolution 3D OSS on a daily scale in 12 depth levels (from 2 m to 200 m). The asymmetric inception3DGAN model with all enhanced structures has the highest accuracy, the average root-mean-squared error (RMSE) is 0.135psu, the average coefficient of determination (R2) is 0.5641 and the percent bias is 0.436%. Comparing with model without enhanced structures, the average RMSE is decreased by 22.41% when adding all the enhancement structures. Besides, temporal and spatial error analysis are also conducted to evaluate the models' performance from different aspects. Finally, the model results are used to analyze common ocean elements, such as water mass properties, dynamic fields and geostrophic velocity fields, demonstrating that the 3D OSS dataset construction approach proposed in this study not only provides some new insights into ocean observations, but also has high application values.","2023-08","2025-04-25 15:32:50","2025-04-25 15:32:50","","","","","184","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, since users are not fully aware of existing features, when submitting new feature requests, redundant requests often appear in the new feature list. It is a waste of time and effort for project contributors to manually identify and reject them, especially in complex systems with many features. Our research is aiming to find a suitable solution to identify redundant feature requests in OSS projects. We have conducted a survey on a well-known Open Source community, Hibernate and gathered all of its feature requests up-to-date. Through studying and categorizing the characteristics of these feature requests, we have found that about 37% of the feature requests were rejected and the most common rejection reason was redundancy. Also we have found that it is very expensive to identify and resolve these redundant feature requests.

A typical procedure to create 3D printed splints is obtaining the geometry of a body segment using a 3D scanner, creating a 3D printable splint model based on the geometry of the body segment, and 3D printing the splint. As technologies of 3D scanning and 3D printing become mature gradually, the main challenge to fabricate 3D printed splint is to create 3D printable splint models. To solve this challenge, researchers have proposed various methods to design 3D splint models. However, most methods require extensive 3D modeling skills that medical professionals are lacking. In this work, a semi-automatic method is proposed to create a 3D printable model. Given the geometry of a body segment obtained through a 3D scanner, the method includes three key steps: (1) create a draft splint lattice structure, (2) optimize the splint structure, and (3) create a 3D printable model based on the optimized structure. All the software adopted for this method is free and readily available, and thus, there is no additional cost to convert from a scanned geometry of a body segment to a 3D printable splint model. Because the majority of the work is done automatically, with initial training, a medical professional should be able to create a 3D printable model using the proposed method, given the geometry of a body segment. The proposed method is demonstrated by creating a 3D printed wrist splint and the demo is uploaded into GitHub, a popular open-source platform.","2021-03-16","2025-04-25 15:32:51","2025-04-25 15:32:51","","","","3","13","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The rule established from the case of Foss vs. Harbottle, which paved way for exploitation of the minority shareholders, giving excessive power at the hands of the office-bearers, has always been a hindrance to secure a protection to the minority shareholders who do not get an opportunity to approach the Court for seeking justice as they are considered unauthorised to do so. The instances whereby the rights of the minority shareholders have been infringed or violated are enormous in number, and the requirement to secure an amicable environment for these small in shareholdings yet large numbers of shareholders has increased with time. Recently, in the judgment, considering the prevalence of the majority rule, the decision was given in favour of the majority shareholders of the Company, posing a threat to the position of the minority shareholders, yet again in the corporate world. Thus, the researcher here, attempts to critically analyse the majority rule, discussing in brief the case of Foss vs. Harbottle developed contrary to the interests of the minority shareholders, and appraise the exceptions provided under the Majority rule which also acts as a measure to protect the rights of minority shareholders. The researcher has tried to analyse the case of Cyrus Mistry trying to identifying as to how the Courts have failed to provide protection to the minority shareholders and this acts like a set back to the same.","2022","2025-04-25 15:32:51","2025-04-25 15:32:51","","4488-4493","","2","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If oral hygiene practice is poor, plaque easily accumulates on the tooth surface, especially in interproximal areas. To maintain a good oral environment, it is mandatory to remove or at least reduce the percentage of plaque formation from the oral cavity. To achieve this, interdental aids should be used along with toothbrushes, as cleansing the teeth only with a toothbrush is not effective. Various interdental aids, like interdental brushes, floss, toothpicks, etc., are now available on the market. The objective of the current survey was to rate knowledge as well as make a comparison between the cleaning effectiveness of interdental brushes and interdental floss to determine which was better at reducing plaque accumulation and, subsequently, dental caries. The survey was accessed by measuring individual plaque and gingival index before and after using interdental cleaning aids.Methodology The objective of the survey was to evaluate and analyze the efficiency of interdental brushes and interdental floss in maintaining oral hygiene among orthodontic patients residing in the Vidarbha region. After receiving approval from the Ethical Committee DMIHER(DU)/IEC/2023/721, a study was conducted over a 30-day period, focusing on a group of 100 individuals aged between 15 and 30 years, and their assessments were analyzed. The patient was briefed about the study and asked to make use of an interdental brush and interdental floss. The gingival index and plaque index were calculated on the same patients before and after the use of the interdental brush and interdental floss to determine which was better at reducing plaque accumulation on the surface of teeth. Descriptive analysis, unpaired for intergroup comparison, and paired T-tests for intragroup comparison were used. The software used was SPSS 24.0 (IBM Corp., Armonk, NY) and GraphPad Prism 7.0 (GraphPad Software, Inc., La Jolla, CA).Result Everyone's tooth surfaces naturally develop a thin layer of plaque biofilm, but the presence of heavy plaque deposits on teeth indicates poor dental hygiene, which can lead to various oral health issues. Failure to improve dental hygiene status can result in problems such as halitosis, gingival issues, periodontal disease, and eventually tooth loss. Dentists play a crucial role in raising awareness about these concerns among their patients and providing education on effective oral care practices, including the use of interdental aids in conjunction with toothbrushes. When comparing the effectiveness of interdental brushes and dental floss in removing plaque, interdental brushes have been found to be more efficient. They not only excel in plaque removal but also contribute to a reduction in gingival problems. The statistical analysis supports this, with a significant p-value of less than 0.01 for both the plaque index and gingival index when using interdental brushes, indicating their superior performance in maintaining oral health.Conclusion The study will help every individual improve their oral hygiene status with the help of an interdental aid and a toothbrush. This will reduce the chances of having gingival and periodontal diseases and eventually reduce the risk of tooth loss.","2023-09-29","2025-04-25 15:32:51","2025-04-25 15:32:51","","","","9","15","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: A comparison of two household surveys was carried out where mothers of the family were interviewed using a structured questionnaire in order to obtain demographic, behavioural and socioeconomic information. In total, 852 and 984 households were included in 1996 and 2009, respectively. Self-reported use of dental floss was assessed dichotomously (yes/no). Poisson regression models were fitted to study the association between sociodemographic variables with the use of dental floss. Proportion ratios (PR) and 95% confidence intervals (95% CI) were reported. Results: The proportion of dental floss use increased from 48% to 59% over 13 years. The probability of dental floss use increased 1.23 times from 1996 to 2009 (PR = 1.23; 95% CI 1.13-1.34). Households with mothers >= 50 years old presented a 28% lower probability of using dental floss than households with mothers <= 35 years old. In households with higher family income and higher educational level of the mother, probabilities of flossing were 90% and 97% higher.

This report describes a semiautomatic approach to decrease the manual reidentification error. This study evaluated the repeatability of surgical outcome measurements using the semiautomatic approach. Furthermore, a step-by-step guide is provided to enable researchers and clinicians to perform the 3D analysis by themselves. Materials and Methods: Evaluating surgical outcome consists of 2 parts. First, the scans are aligned at the anterior cranial base. Second, a semiautomatic approach is used to place 3 dental reference points at exactly the same sites of the pre-and postoperative maxilla. Because the maxilla is repositioned during surgery but otherwise unaltered, the reference points should be identical if the pre-and postoperative scans are aligned at the maxilla. Therefore, the authors propose the insertion of reference points on the preoperative scan and then repositioning a copy of the preoperative reference points relative to the postoperative scan. To align the reference points on the postoperative scan, the hard palate is used as a mutual maxillary reference structure. A reproducibility test was performed in 10 participants by analyzing the difference between repeated measurements. Results: Repeated linear measurements differed by less than 0.1 mm along all 3 axes (standard deviations, < 0.1 mm). The 2 largest differences between repeated measurements were 0.33 mm along the superoinferior axis and 0.29 along the anteroposterior axis. Repeated rotational measurements differed by less than 0.1 degrees around all 3 axes (standard deviations, <= 0.1 degrees). Conclusion: The semiautomatic approach showed excellent linear and angular repeatability. The algorithm can be implemented in the clinical evaluation of orthognathic surgical outcome and postoperative relapse.

Although the quality of developers' contributions should be the only factor influencing the evaluation of the contributions to OSS projects, recent studies have shown that diversity issues are correlated with the acceptance or rejection of developers' contributions. Objective: This paper assists this emerging state-of-the-art body on diversity research with the first empirical study that analyzes how developers' perceptible race and ethnicity relates to the evaluation of the contributions in OSS. We also want to create awareness of the racial and ethnic diversity in OSS projects. Methodology: We performed a large-scale quantitative study of OSS projects in GitHub. We extracted the developers' perceptible race and ethnicity from their names in GitHub using the Name-Prism tool and applied regression modeling of contributions (i.e, pull requests) data from GHTorrent and GitHub. Results: We observed that (1) among the developers whose perceptible race and ethnicity was captured by the tool, only 16.56 percent were perceptible as Non-White developers; (2) contributions from perceptible White developers have about 6-10 percent higher odds of being accepted when compared to contributions from perceptible Non-White developers; and (3) submitters with perceptible non-white races and ethnicities are more likely to get their pull requests accepted when the integrator is estimated to be from their same race and ethnicity rather than when the integrator is estimated to be White. Conclusion: Our initial analysis shows a low number of Non-White developers participating in OSS. Furthermore, the results from our regression analysis lead us to believe that there may exist differences between the evaluation of the contributions from different perceptible races and ethnicities. Thus, our findings reinforce the need for further studies on racial and ethnic diversity in software engineering to foster healthier OSS communities.","2022-08-01","2025-04-25 15:32:51","2025-04-25 15:32:51","","2955-2968","","8","48","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The endpoint of the baking process is traditionally determined by subjective human experts and indirect temperature measurements, which can often result in unstandardized production. Current colorimeters are unavailable for onsite measurement due to limitations associated with contact measurement and environmental temperature. Instead of the abovementioned human experts and tabletop colorimeters, a handheld colorimeter was built based on the expertise of human specialists and utilizing a tabletop colorimeter and other optical steps. First, the selected samples were used to determine the upper and lower limits distinguishing light, medium, and heavy baking levels by using a tabletop colorimeter. Second, independent light sources and spectrometers were utilized to choose the characteristic and reference wavelengths at 450 and 830 nm, separately. Third, the handheld colorimeter, instead of human expert observation, was designed with functions such as distance sensing and Internet of Things capabilities. The baked index was derived from the calibration reflection and established statistical models. Here, the calibration reflection was defined by the normalized intensity at 450 nm relative to 830 nm, and statistical models were founded from the determined samples of upper and lower limits at 95-700 mm. The developed handheld colorimeter demonstrated high agreement rates of 96.84% and 93.86% in separate comparisons with tabletop colorimeters and human experts, respectively. This work indicated the accurate and stable recognition of samples within two limits and overall. Field validation confirmed the performance of remote, economic, and onsite recognition against environmental temperature and noise.","2024-12-23","2025-04-25 15:32:51","2025-04-25 15:32:51","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of present study was to fully characterize our anorganic bone, InterOss (R), by physical and chemical methods and to compare it with another anorganic bone, Bio-Oss (R) that has been commercially distributed in dental bone graft substitute market since 1995. InterOss (R) anorganic bone had been successfully prepared by chemical treatment (NaOH and H2O2) and low temperature (350 degrees C) annealing process with an extremely low heating rate (<0.3 degrees C min(-1)). Commercially available Bio-Oss (R) anorganic bone was chosen for comparison. The physical and chemical analysis indicated that the pore structure, microstructure, phase structure, and chemical composition of InterOss (R) is substantially equivalent to that of Bio-Oss (R). The BET analysis also showed that the inner surface area of InterOss (R) is comparatively higher than that of Bio-Oss (R). Specially, the protein analysis showed that the content of residual protein of InterOss (R) is relatively lower than that of Bio-Oss (R). Based on an equivalency to Bio-Oss (R) in terms of physical and chemical characterization with both higher inner surface area and lower residual protein content, the InterOss (R) can be a promising candidate as dental bone grafting material in periodontal and maxillofacial surgery.

The antioxidant tea polyphenol (TPP) was embedded into W/O microemulsion, which was further encapsulated into multiple emulsion (Multi-E) together with functional soluble dietary fiber (SDF). The physicochemical properties indicated that the nanoemulsion-based edible film (NEF) improved the morphology of FF and reduced the crystallinity of the film by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water vapor permeability increased gradually and rose to only 0.99% after 5 h, resulting in the water activity of FF at a low level (<= 0.51) during the storage period. The TPP inside was released at a constant rate (<= 18.10%) on the surface, and such a rate was accelerated in the simulated gastrointestinal environment, especially in intestine reaching 60.12% after 5 h of digestion. Besides, the effect of NEF on the flavor was also evaluated and the contents of ketones, phenols, and pyrazines increased, which displayed a regulating effect on the overall flavor of FF by blocking the external moisture and suppressing the microorganism activity. In summary, the NEF effectively enhanced the flavor and taste of FF, controlled the release of TPP, and reduced the water activity during the storage, thereby extending the shelf life.","2022-07","2025-04-25 15:32:52","2025-04-25 15:32:52","","2370-2380","","7","10","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper tries to account for these problems, namely: (1) the Lewis base, or electron donor component, is much greater than the Lewis acid or electron-acceptor component because of the reference values for water chosen in the original GvOC theory. A direct comparison of the acidic component with the basic one of the same materials has no meaning. A new reference scale for water which is able to overcome this problem is suggested. For the calculation of acid-base components, a best-fit approach is proposed which does not require any starting information about the liquids or polymers and can yield estimates of the acid-base parameters for both the liquids and the polymers involved; (2) the strong dependence of the value of the acid-base components on the three liquids employed is due to ill-conditioning of the related set of equations, an intrinsic and purely mathematical feature which cannot be completely cured by any realistic improvement in experimental accuracy. To reduce or eliminate the effect, one only needs a proper set of liquids, representative of all kinds of different solvents: (3) the negative coefficients appear as a simple consequence of measurement uncertainty, combined with the possible ill-conditioning of the equation set. We cannot exclude, however, that in some cases they could have a different origin.","2000","2025-04-25 15:32:52","2025-04-25 15:32:52","","235-272","","2","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and methods Seventy-five adult subjects showing approximately 40% proximal gingival bleeding were randomized to receive OHt (1 session weekly over 8 weeks) using toothbrush and dental floss or toothbrush alone. The subjects were then followed over 180 days without professional guidance. Primary outcomes were mean interproximal Gingival Index (GI) and GI = 2 (gingival bleeding). Mixed linear models were used for the comparison between groups (p < 0.05). Results68 subjects received OHt, 48 subjects completed the 180-day follow-up. Subjects maintained adequate oral hygiene routines. Besides a reduction in gingival inflammation, no alterations in gingival status were observed among groups, subjects additionally instructed to use dental floss showing a mean interproximal GI = 2 of 12.8 +/- 2.5 compared with 19.8 +/- 2.2 for subjects limited to tooth brushing alone. Conclusions OHt intensive training promotes gingival health and maintenance lasting at least 6 months without professional supervision reinforcing important principles: (i) dental health professionals should dedicate time training and motivating their patients to reach adequate self-performed plaque control; and (ii) the adjunctive use of dental floss appears essential to reduce interproximal gingival inflammation in subjects with intact interdental papillae. Clinical relevance Dentists need to invest time in training/motivating/engage their patients to achieve adequate OH; adjunct flossing in subjects with papilla filling the interdental space appears essential to reach and maintain gingival health.

Trees in urban parks can play an important role in mitigating runoff and delivering other ecosystem services. Park managers, E-NGOs, citizen scientists and others are increasingly called upon to evaluate the possible consequences of changes in park management such as, e.g., tree removal. Here, we present an unorthodox approach to hydrological modelling and its potential use in local policy making regarding urban greenery. The approach consists of a minimalist field campaign to characterize vegetation and soil moisture status combined with a novel model calibration using freely available data and software. During modelling, we were able to obtain coefficients of determination (R-2) of 0.66 and 0.73 for probe-measured and simulated soil moisture under tree stand and park lawn land covers respectively. The results demonstrated that tree cover had a significant positive effect on the hydrological regime of the locality through interception, transpiration and effects on soil moisture. Simulations suggested that tree cover was twice as effective at mitigating runoff than park lawn and almost seven times better than impervious surfaces. In the case of a potential replacement of tree vegetation in favour of park lawn or impervious surfaces an increase in runoff of 14% and 81% respectively could be expected. The main conclusion drawn from our study was that such an approach can be a very useful tool for supporting local decision-making processes as it offers a freely available, cheap and relatively easy-to-use way to describe the hydrological consequences of landcover change (e.g., tree removal) with sufficient accuracy.

We introduce a novel method for determining the data of a weak electrolyte by the nonlinear regression of effective electrophoretic mobility versus buffer composition dependence when measured in a set of BGEs with various pH. To correct the experimental data for zero ionic strength we use the extended Debye-Huckel model and Onsager-Fuoss law with no simplifications. Contrary to contemporary approaches, the nonlinear regression is performed on limiting mobility data calculated by PeakMaster's correction engine, not on the raw experimental mobility data. Therefore, there is no requirement to perform all measurements at a constant ionic strength of the set of BGEs. We devised the computer program AnglerFish that performs the necessary calculations in a user-friendly fashion. All thermodynamic pKa values and limiting electrophoretic mobilities for arbitrarily charged substances having any number of ionic forms are calculated by one fit. The user input consists of the buffer composition of the set of BGEs and experimentally measured effective mobilities of the inspected weak electrolyte.","2020-04","2025-04-25 15:32:52","2025-04-25 15:32:52","","493-501","","7-8, SI","41","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the mass changes incurred by novel and more recently developed derivatizations are not accommodated by most spectral assignment programs, necessitating manual assignment which increases both the difficultly and the likelihood of error. AssignMALDI is a software tool designed to create glycan databases with customized derivatizations (labels) and automatically assign glycan masses in MALDI-TOF spectra using the new database. It can also average peak intensities across multiple spectra and prepare publication-ready assignment tables.

It applies to well-mixed surface water layers, including the epilimnion of stratified lakes, and the output data are average values over the considered water column. Based on intermediate formation yields from the parent compound via the different photochemical pathways, the software can also predict intermediate formation kinetics and overall yield. APEX is based on a photochemical model that has been validated against available field data of pollutant phototransformation, with good agreement between model predictions and field results. The APEX software makes allowance for different levels of knowledge of a photochemical system. For instance, the absorption spectrum of surface water can be used if known, or otherwise it can be modelled from the values of DOC. Also the direct photolysis quantum yield can be entered as a detailed wavelength trend, as a single value (constant or average), or it can be defined as a variable if unknown.

With advances in digital planning, surgical techniques, orthognathic surgery becomes increasingly safe, however, still a physiological factor that challenges the surgeon: bone repair. The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss (R) Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss (R)) and 10% collagen fibres in a block form and is sterilized by gamma-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss (R) Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss (R) Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.","2023-09-10","2025-04-25 15:32:52","2025-04-25 15:32:52","","","","","5","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted a large, multicenter, prospective, observational study to confirm the REGOMA data in a real-world setting. Patients and methods: The major inclusion criteria were histologically confirmed diagnosis of glioblastoma according to the World Health Organization (WHO) 2016 classification and relapse after radiotherapy with concurrent/adjuvant temozolomide treatment, good performance status [Eastern Cooperative Oncology Group performance status (ECOG PS 0-1)] and good liver function. Regorafenib was administered at the standard dose of 160 mg/day for 3 weeks on/1 week off. Brain magnetic resonance imaging was carried out within 14 days before starting regorafenib and every 8-12 weeks. The primary endpoint was overall survival (OS). The secondary endpoints were progression -free survival (PFS), objective response rate, disease control rate (DCR), safety and health-related quality of life. The Response Assessment in Neuro-Oncology (RANO) criteria were used for response evaluation and Common Terminology Criteria for Adverse Events (CTCAE) version 5 for assessment of adverse events (AEs). Results: From September 2020 to October 2022, 190 patients with recurrent glioblastoma were enrolled from 30 cancer centers in Italy: their median age was 58.5 years [interquartile range (IQR) 53-67 years], 68% were male and 85 (44.7%) were in optimal clinical condition (ECOG PS 0). The number of patients taking steroids at baseline was 113 (60%); the second surgery was carried out in 39 (20.5%). O6-methylguanine-DNA methyltransferase (MGMT) was methylated in 80 patients (50.3%) and 147 (92.4%) of the patients analyzed had isocitrate dehydrogenase (IDH) wild type. The median follow-up period was 20 months (IQR 15.6-25.5 months). The median OS was 7.9 months ([95% confidence interval (CI) 6.5-9.2 months] and the median PFS was 2.6 months (95% CI 2.3-2.9 months). Radiological response was partial response and stable disease in 13 (7.3%) and 26 (14.6%) patients, respectively, with a DCR of 21.9%. The median number of regorafenib cycles per patient was 3 (IQR 2.0-4.0). Grade 3-4 drug-related adverse events were reported in 22.6% of patients. A dose reduction due to AEs was required in 36% of patients. No deaths were considered as treatment-related AEs. Conclusions: This large, real -world observational study showed similar OS with better tolerability of regorafenib in patients with relapsed glioblastoma compared with the REGOMA study.","2024-04","2025-04-25 15:32:53","2025-04-25 15:32:53","","","","4","9","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Material and MethodsSurfaces of a novel particulate bovine bone graft, Moa-Bone((R)) were compared with Bio-Oss((R)) using scanning electron microscopy. Six sheep then had maxillary sinus grafting bilaterally, covered with BioGide((R)). Grafted maxillae were harvested after 4, 6 and 12weeks. Healing was described for half of each site using resin-embedded ground sections. For the other half, paraffin-embedded sections were examined using tartrate resistant acid phosphatase staining for osteoclast activity, runt-related transcription factor2 immunohistochemistry for pre-osteoblasts and osteoblasts and proliferating cell nuclear antigen for proliferative cells. ResultsMoa-Bone((R)) had a smoother, more porous fibrous structure with minimal globular particles compared with Bio-Oss((R)). After 4weeks, woven bone formed on both grafts and the Moa-Bone((R)) particles also showed signs of resorption. After 12weeks, Moa-Bone((R)) continued to be resorbed, however Bio-Oss((R)) did not; both grafts were surrounded by maturing lamellar bone. Moa-Bone((R)) was associated with earlier evidence of runt-related transcription factor 2-positive cells. Moa-Bone((R)) but not Bio-Oss((R)) was associated with strong tartrate resistant acid phosphatase-positive osteoclasts on the graft surface within resorption lacunae at both 4 and 6weeks post-grafting. ConclusionBoth materials supported osseous healing and maturation without inflammation. Moa-Bone((R)) showed marked osteoclast activity after 4 and 6weeks and demonstrated positive attributes for grafting, if complete remodeling of the graft within the site is desired. Further optimization of Moa-Bone((R)) for maxillofacial applications is warranted.","2018-02","2025-04-25 15:32:53","2025-04-25 15:32:53","","80-90","","1","53","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

During variable-parameter milling, particularly high-precision machining, machining parameters vary, and associated discrepancies in vibration signals are small. In this scenario, signal features that are extracted by hand or via deep learning methods cannot typically distinguish machining states via classification models. To solve this problem, a sequence labeling model developed using a stacked bidirectional long short-term memory network with a conditional random field layer (stacked-BiLSTM-CRF) is proposed in this study to automatically label and intercept vibration signals. The stacked BiLSTM receives the shallow features obtained by the short-time Fourier transform of the vibration signals and then outputs the extracted deep features to capture the before and after dependence of the signals. The stacked BiLSTM is then extended by stacking a CRF layer to explicitly model the dependence of signal labels. In a more accurate labeling scenario, the fast low-cost online semantic segmentation algorithm (FLOSS) is used to acquire more fine-grained signal boundary locations after obtaining the frame-level signal label using the stacked BiLSTM-CRF model. In addition, to evaluate model performance, a novel evaluation index for signal labeling is proposed. The feasibility and effectiveness of the proposed method are verified using the vibration signals collected from variable parameter cutting experiments, and results show that the proposed model achieves the best labeling performance of tested methods in nearly all scenarios.","2023-01","2025-04-25 15:32:53","2025-04-25 15:32:53","","","","","55","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The first concerns how the courtship plot of the nineteenth-century novel responded to, and helped to shape, scientific ideas of sexual competition and selection. In The Mill on the Floss (1860), George Eliot strikingly prefigures Darwin's later work on sexual selection, drawing from her own extensive knowledge of the wider debates within which evolutionary theory developed. Maggie Tulliver's characterisation allows Eliot to explore the ethical complexities raised by an increasingly powerful scientific naturalism, where biology is seen to be embedded within morality in newly specific ways. The second strand of the paper examines the extension of scientific method to human mind and motivation which constituted the new psychology. It argues that there are crucial continuities of long-established ethical and religious ideas within this increasingly naturalistic view of human mind and motivation. The contention that such ideas persist and are transformed, rather than simply jettisoned, is illustrated through the example of Thomas Henry Huxley's 1874 essay on automata. Turning finally to focus on Olive Schreiner's Undine (1929) and From Man to Man (1926), the paper explores the importance of these persistent ethical and religious ideas in two novels which remained unpublished during her lifetime. It argues that they produce both difficulty and opportunity for imagining love plots within the context of increasingly assertive biological and naturalistic accounts of human beings.","2009","2025-04-25 15:32:53","2025-04-25 15:32:53","","26-52","","1","14","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Five-millimeter bone defects were created in the cranial bones of 15, 15-week-old, male Sprague-Dawley rats, five of which were left unfilled (Group A), five were filled with Bio-Oss (R) (Group B), and five were filled with Bio-Oss (R) and a collagen membrane (Group C). They were evaluated by micro-computed tomography (micro-CT) Weeks 8 after bone defect creation. The animals were euthanized in Week 8, and tissue samples were taken. The sampled tissue was evaluated by the Kawamoto technique for preparing nondecalcified frozen sections. On micro-CT, radiopacities in the bone defects were evident in Groups B and C, but not in Group A. The amount of radiopacity tended to be greater in Group C than in Group B. Histologically, no new bone formation was observed in Group A. In Groups B and C, new bone formation around the Bio-Oss (R) was apparent and some osteoblastic cells were observed along the new bone. The Bio-Oss (R) was not absorbed up to Week 8, suggesting that it may be a potential bone regeneration scaffold. The combined use of a collagen membrane anchored the Bio-Oss (R) in close contact with the cranial bone, suggesting that it may help create a favorable environment for bone formation. The combination of Bio-Oss (R) and a collagen membrane in GBR may be useful for bone defect regeneration.","2018-01","2025-04-25 15:32:53","2025-04-25 15:32:53","","79-83","","1","27","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A compound library of 288 Schiff bases was designed based on compound 10, and a pharmacophore search was performed. Structural analysis of the top scoring hits and a docking study were used to select the best derivatives for the synthesis. Chemical synthesis and structural elucidation of compounds 16a-h were discussed. The antiproliferative activity of 16a-h was evaluated against three cancer (MCF7, A2780 and HT29, IC50 = 0.01-40.50 mu M) and one normal MRC5 (IC50 = 1.27-24.06 mu M) cell lines using the MTT assay. The results revealed the highest antiproliferative activity against MCF7 cells for 16g (IC50 = 0.01 mu M) with an exceptionally high selectivity index of (SI = 578). Cell cycle analysis of MCF7 cells treated with compound 16g revealed a cell cycle arrest at the G(2)/M phase. In addition, compound 16g induced a dose-dependent increase in apoptotic events in MCF7 cells compared to the control. In silico target prediction of compound 16g showed six potential targets that could mediate these activities. Molecular docking analysis of compound 16g revealed high binding affinities toward COX-2, MAP P38 alpha, EGFR, and CDK2. The results of the MD simulation revealed low RMSD values and high negative binding free energies for the two complexes formed between compound 16g with EGFR, and CDK2, while COX-2 was in the third order. These results highlighted a great potentiality for 16g to inhibit both CDK2 and EGFR. Taken together, the results mentioned above highlighted compound 16g as a potential anticancer agent.","2021-07","2025-04-25 15:32:53","2025-04-25 15:32:53","","","","13","26","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We investigated an interworking mechanism; based on a web service interface between an inventory and fault management systems and developed prototypes of them as part of an operation support system (OSS), which is capable of managing not only a core network and a metro ring network, but also a customer network.

AgHA was synthesized by a chemical precipitation method. After characterization, AgHA was mixed with Bio-Oss((R)) at three ratios: 1:1, 1:2, and 1:4 by weight. Then, Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were used to test the antibacterial activity of the mixture. Human periodontal ligament fibroblasts and rat bone marrow stromal cells were selected for cytocompatibility experiments. According to results, the peak value of the size of the AgHA was concentrated in the 100-200 nm range, and AgHA particles consisted of short rods. It was confirmed that the structure of AgHA was similar to that of standard hydroxyapatite. All three mixture ratios exhibited obvious antimicrobial properties, which increased with increasing AgHA. According to the effects on the expression of bacterial virulence genes, groups 1:1 and 1:2 both negatively affected Pg and Fn more significantly than group 1:4. Cytotoxicity experiments showed that 1:1 caused little cytotoxicity, while groups 1:2 and 1:4 exerted no significant cytotoxicity. Considering its biological compatibility and antibacterial activity, group 1:2 is the most recommended. (c) 2017 Wiley Periodicals, Inc.

The study objective was to validate two complementary indicators, i.e., the OIDP (Oral Impacts on Daily Performances) and Oral Satisfaction 0-10 Scale (OSS), in two qualitatively different socio-demographic samples of the Spanish adult population, and to analyse the factors affecting both perspectives of well-being. Methods: A cross-sectional study was performed, recruiting a Validation Sample from randomly selected Health Centres in Granada (Spain), representing the general population (n = 253), and a Working Sample (n = 561) randomly selected from active Regional Government staff, i. e., representing the more privileged end of the socio-demographic spectrum of this reference population. All participants were examined according to WHO methodology and completed an inperson interview on their oral impacts and oral satisfaction using the OIDP and OSS 0-10 respectively. The reliability and validity of the two indicators were assessed. An alternative method of describing the causes of oral impacts is presented. Results: The reliability coefficient (Cronbach's alpha) of the OIDP was above the recommended 0.7 threshold in both Validation and Occupational samples (0.79 and 0.71 respectively). Test-retest analysis confirmed the external reliability of the OSS (Intraclass Correlation Coefficient, 0.89; p < 0.001) Some subjective factors (perceived need for dental treatment, complaints about mouth and intermediate impacts) were strongly associated with both indicators, supporting their construct and criterion validity. The main cause of oral impact was dental pain. Several socio-demographic, behavioural and clinical variables were identified as modulating factors. Conclusion: OIDP and OSS are valid and reliable subjective measures of oral impacts and oral satisfaction, respectively, in an adult Spanish population.

The metabotropic glutamate receptors (mGlus) belong to family C of the G-protein-coupled receptors (GPCRs). The eight mGlus identified to date are classified into three groups based on their structure, preferred signal transduction mechanisms, and pharmacology (group I: mGlu(1) and mGlus; group II: mGlu(2) and mGlu(3); group III: mGlu(4), mGlu(6), mGlu(7), and mGlu(8)). Noncompetitive antagonists, also known as negative allosteric modulators (NAMs), of mGlus offer potential therapeutic applications in diseases such as pain, anxiety, gastresophageal reflux disease (GERD), Parkinson's disease (PD), fragile X syndrome, and addiction. The development of structure activity relationships (SAR) in a (3-cyano-5-fluorophenyl)biaryl series using our functional cell-based assay is described in this communication. Further characterization of a selected compound, 3-fluoro-(5-(2-methylbenzo[d]thiazol-5-yl)benzonitrile, in additional cell based assays as well as in vitro assays designed to measure its metabolic stability and protein binding indicated its potential utility as an in vivo tool. Subsequent evaluation of the same compound in a pharmacokinetic study using intraperitoneal dosing in mice showed good exposure in both plasma and brain samples. The compound was efficacious in a mouse marble burying model of anxiety, an assay known to be sensitive to mGlus antagonists. A new operant model of addiction termed operant sensation seeking (OSS) was chosen as a second behavioral assay. The compound also proved efficacious in the OSS model and constitutes the first reported example of efficacy with a small molecule mGlu(5) NAM in this novel assay.","2011-08","2025-04-25 15:32:53","2025-04-25 15:32:53","","471-482","","8","2","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A total of 2763 Asian Americans aged 20 and older were included in this analysis. The primary predictor, acculturation score, was determined by three questions: (i) language spoken at home (higher score for English), (ii) country of birth (higher score for United States) and (iii) length of time in the United States. Dental floss use, dental visits and unmet dental care needs were included as outcomes in this study. Descriptive statistics and logistic regressions were used to analyse the samples.ResultsAcculturation was significantly associated with dental health behaviours: Individuals with higher levels of acculturation were more likely than less acculturated individuals to use dental floss (81.0% vs. 63.9%, respectively) and visit the dentist regularly (76.7% vs. 66.9% respectively). Insurance status moderated the association between acculturation and dental visits: Acculturation was significantly associated with dental visits in the past year among insured individuals (OR = 1.70, 95% CI: 1.29-2.23), but not among uninsured individuals. Unmet dental care needs were present in 11.1% of participants. While costs and insurance were the top two determinants of access to care, individuals with and without insurance differed with regard to their third major reason for unmet dental care needs: Being `too busy' and not wanting to spend money on dental care.ConclusionsAmong the Asian population in the United States, those with high acculturation scores were more likely to engage in dental flossing and visit the dentist regularly compared to those Asians with lower acculturation scores. To encourage dental flossing and regular dental visits among Asians with lower acculturation scores, cultural adaptation and language accessibility suggests being considered. Future research is necessary to confirm the moderating effect of insurance status on the association between acculturation and regular dental visits. Additionally, our findings emphasize the impact of costs and insurance on access to dental care among Asians in the United States, highlighting the importance of future public health programmes in addressing these barriers.","2024-02","2025-04-25 15:32:53","2025-04-25 15:32:53","","101-110","","1","52","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results of maximum absolute errors and maximum relative errors (MREs) in SQSSTCPs/SSTCPs, induced by errors in LSTCPs or contact angles, show that most SQSSTCPs/SSTCPs can be evaluated at moderate accuracy from the lowest condition number liquid triplets, assuming that |Delta theta(i)|=1 degrees and [GRAPHICS] =0.1mN/m (i=1,2,3, k=LW, +, -). This confirms the validity of the vOCG approach. The accuracy of each SQSSTSCP/SSTCP declines with increasing theta(i) or decreasing parameter when theta(i)>0 or a critical value, provided the other two contact angles are kept fixed. This explains the underlying reasons for negative SQSSTCPs. At the scale proposed by vOCG, dimethyl sulphoxide is not suggested for use. Comparing with the MREs obtained at vOCG scale, considering the acidity of diiodomethane improves the accuracy of [GRAPHICS] ; using the scales proposed by Lee and Shen do not affect the accuracy of SSTCPs, but using the scale proposed by Della Volpe et al. improves the accuracy of SSTCPs at low theta(2) and theta(3) while declines that at high ones.

This increasing attention is a result of the remarkable growth in the number of OSS applications in recent years. Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest. These findings have implications for both the OSS research community and OSS practitioners.","2015-01-02","2025-04-25 15:53:55","2025-04-25 15:53:55","","28-46","","1","25","","","","","","","","","","English","","","","","","","Place: 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA Publisher: TAYLOR & FRANCIS INC Type: Article","","","","development sustainability; open source software project; OSS project success; software project management; success measures' interrelationships","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Survivability, critical for maintaining project quality and trustworthiness, is closely linked to issue activity, as unresolved issues reflect a decline in maintenance capacity and problem-solving ability. Thus, analyzing issue retention rates provides valuable insights into a project's health. This study evaluates OSS survivability by identifying the features that influence issue activity and analyzing their relationships with survivability. Kaplan-Meier survival analysis is employed to quantify issue activity and visualize trends in unresolved issue rates, providing a measure of project maintenance dynamics. A random forest model is used to examine the relationships between project features-such as popularity metrics, community engagement, code complexity, and project age-and issue retention rates. The results show that stars significantly reduce issue retention rates, with rates dropping from 0.62 to 0.52 as stars increase to 4000, while larger codebases, higher cyclomatic complexity, and older project age are associated with unresolved issue rates, rising by up to 15%. Forks also have a nonlinear impact, initially stabilizing retention rates but increasing unresolved issues as contributions became unmanageable. By identifying these critical factors and quantifying their impacts, this research offers actionable insights for OSS project managers to enhance project survivability and address key maintenance challenges, ensuring sustainable long-term success.","2025-01","2025-04-25 15:53:55","2025-04-25 15:53:55","","","","2","15","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open source software; software maintenance; survivability; Kaplan-Meier survival function; random forest","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most risks or security vulnerabilities, besides inadverted errors, originates from criminal activity, which anonymously thrives on the Web and can outbreak any organization, mainly for profit but sometimes just for the challenge of doing it. Consequently, creating and managing a security system is often the main form of precaution and it is the solution that guarantees better success rates.

System changes are often done without considering their effects on the system structure. These changes often introduce structural anomalies between the concrete (as-built) and the conceptual (as-designed) architecture which can impede program understanding. The problem of architectural drift is especially pronounced in open source systems, where many developers work in isolation on distinct features with little co-ordination. In this paper we present our experiences with repairing the architectures of two large open source systems (the Linux operating system kernel and the VIM text editor) to aid program understanding. For both systems, we were successful in removing many structural anomalies from their architectures.","2000","2025-04-25 15:53:55","2025-04-25 15:53:55","","48-59","","","","","","","INTERNATIONAL WORKSHOP ON PROGRAM COMPREHENSION","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc, Tech Comm Software Engn ISSN: 1092-8138 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""
-"EXB28DKV","journalArticle","2001","McGowan, D","Legal implications of open-source software","UNIVERSITY OF ILLINOIS LAW REVIEW","","0276-9948","","","The proliferation of computer technology and the advent of the Internet have created many new relationships and problems that raise questions about traditional legal and economic principles. The development of “open-source” or “free” software is an example of this phenomenon. Unlike the traditional producers of computer software - Microsoft for example - open-source software is often developed by computer programmers from all over the world, each submitting contributions to the code, and distributed without charge or for a minimal fee. Open-source software is generally passed from programmer to programmer, with the understanding that improvements may be made, but that the improvements must be distributed freely, without any attempt to “privatize” the program. The existence of such relationships among programmers raise several interesting questions. First, how do large-scale open-source projects come into being? One open-source project, the GNU/Linux operating system, even threatens the market share of Microsoft's operating systems - a feat that calls traditional economic theories on the operation of the firm into question. A more important question is whether the open-source model is sustainable and generalizable. Ultimately, one wonders what role the law will play in the open-source community - a community that seems to operate in the absence of traditional legal principles. In this article, which was introduced at the University of Illinois College of Law Symposium on Intellectual Property Challenges in the Next Century, Professor McGowan addresses these questions. Using the GNU/Linux operating system as a case study, he probes the organization of the open-source community and the philosophies of its leading members in order to understand how traditional firm models, intellectual property, and contract law might apply. Professor McCowan concludes by reviewing recent attempts by courts to impose traditional principles in computer software transaction disputes. Ultimately, it appears that the open-source community cannot be neatly categorized. Although many traditional firm theories - such as the formation of a hierarchy - and legal principles - such as copyright - do apply to the open-source model, these theories and principles are employed in creative ways not previously envisioned.","2001","2025-04-25 15:53:55","2025-04-25 15:53:55","","241-304","","1","","","","","","","","","","","English","","","","","","","Place: COLLEGE OF LAW-76 LAW BLDG 504 E PENNSYLVANIA AVE, CHAMPAIGN, IL 61820 USA Publisher: UNIV ILLINOIS Type: Article; Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, if OSS have few contributors and are lacking in maintenance activities, such as bug fixes, are used, it can lead to significant costs and resource allocation due to maintenance discontinuation. Since OSS are developed by a diverse group of contributors, the consistency of their involvement may vary, making continuous support and maintenance unpredictable. Therefore, it is necessary to identify the status of each OSS to avoid increased maintenance costs when selecting OSS for use. To address these issues, we use polynomial regression to predict trends in bug-fixing activities and evaluate the survivability of OSS accordingly. We predict the trend of bug-fixing activities in OSS, using factors such as popularity, number of contributors, and code complexity. A lower trend value indicates more vigorous activity. In this paper, we conduct data collection and extraction, generating model, and model testing and evaluation to predict survivability using these data. After collecting data through various tools, the models of different degrees are generated using K-fold cross-validation. The model with the highest performance is selected based on the RMSE (Root Mean Squared Error) and RSE (Residual Standard Error). Then, the chosen model is employed to predict the survivability of OSS and compare it with actual outcomes. This method is experimented with on OSS used in the KakaoTalk commercial messenger app. As a result, several OSS are predicted to have low survivability, and among them, five are analyzed. It is observed that, in reality, activities such as delayed or discontinued release updates occurred. These findings can support OSS users in selecting OSS for cost-saving purposes and alert OSS administrators to the need for solutions to ensure project survival.","2024-04","2025-04-25 15:53:55","2025-04-25 15:53:55","","","","7","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","GitHub; open source software; software maintainability; polynomial regression; survivability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: “situated learning” (the process of acting knowledgeably and purposefully in the world) and “identity construction” (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.","2009","2025-04-25 15:53:56","2025-04-25 15:53:56","","9-50","","4","25","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article; Proceedings Paper","","","","legitimate peripheral participation; communities of practice; qualitative study; open source projects; open source software community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.","2009","2025-04-25 15:53:56","2025-04-25 15:53:56","","532-549","","3-4","109","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Internet; Social networks; Open systems; Consumer behaviour; User studies","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the project, we will use both quantitative and qualitative metrics to evaluate the health of OSS projects. The quantitative metrics will be gathered through automated crawling of meta information such as the number of contributors, commits and lines of code. Qualitative metrics will be gathered for selected “critical” projects through manual analysis and automated tools, including aspects such as sustainability, funding, community engagement and adherence to security policies. The results of the analysis will be presented on a user-friendly web platform, which will allow users to view the health of individual OSS projects as well as the overall health of the OSS ecosystem. With this approach, the CrOSSD project provides a comprehensive and up-to-date view of the health of OSS projects, making it easier for developers, maintainers and other stakeholders to understand the health of OSS projects and make informed decisions about their use and maintenance.","2023","2025-04-25 15:53:56","2025-04-25 15:53:56","","156-159","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Amazon Science; Baidu; Megagon Labs; Zhipu AI; Google; Booking Com; eBay; Bloomberg Engn; Netflix; ACM SIGWEB; Univ Texas Austin, Sch Informat; Data World; Inst Fdn Machine Learning Type: Proceedings Paper","","","","software security; open-source software; open-source health; quality monitoring","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.","2013-08","2025-04-25 15:53:56","2025-04-25 15:53:56","","619-643","","4","44","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","Open Source Software; Social Networks; Decision-making; Experiential Learning; License Choice; Vicarious Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nowadays, it is almost impossible for people not using OSS in every interaction they have with technology. This fact is a tremendous success for OSS but such evolution and adoption has not always followed the intended path and some relevant deviations have occurred during such long journey. This paper provide an overview of the evolution of OSS in the three mentioned areas (research, technology, and business) highlighting the main aspects and identifying the current trends that will be the basis for its future evolution.","2019","2025-04-25 15:53:56","2025-04-25 15:53:56","","61-67","","","556","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","Backup Publisher: IFIP WG 2 13 ISSN: 1868-4238 Type: Proceedings Paper","","","","OSS business; OSS evolution; OSS research; OSS technology","","Bordeleau, F; Sillitti, A; Meirelles, P; Lenarduzzi, V","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With dual licensing, a firm releases the same software product under both a traditional proprietary license and an open source one. We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of “going open source” and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.","2011-03","2025-04-25 15:53:56","2025-04-25 15:53:56","","22-38","","1","22","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open-source software; business models; game theory; learning by doing; principal/agent; programmer compensation; programmer incentives; signalling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Substantial research was done to investigate central projects such as Linux kernel but we have only a limited understanding of how the periphery of the larger OSS ecosystem is interconnected through technical dependencies, code sharing, and knowledge flows. We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-25 15:53:56","2025-04-25 15:53:56","","3","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Assoc Comp Machinery Special Interest Grp Software Engn Type: Proceedings Paper","","","","Software Ecosystems; Empirical Software Engineering; Software Measurement","","Dumas, M; Pfahl, D; Apel, S; Russo, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While open source software has similarly distributed decision making and involves code and information flows similar to those in ordinary supply chains, the actual networks necessary to quantify and communicate risks in software supply chains have not been constructed on large scale. This work proposes to close this gap by measuring dependency, code reuse, and knowledge flow networks in open source software. We have done preliminary work by developing suitable tools and methods that rely on public version control data to measure and comparing these networks for R language and emberjs packages. We propose ways to calculate the three networks for the entirety of public software, evaluate their accuracy, and to provide public infrastructure to build risk assessment and mitigation tools for various individual and organizational participants in open sources software. We hope that this infrastructure will contribute to more predictable experience with OSS and lead to its even wider adoption.","2018","2025-04-25 15:53:56","2025-04-25 15:53:56","","458-459","","","","","","","Proceedings of the IEEE-ACM International Conference on Software Engineering Companion","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; Microsoft Res ISSN: 2574-1926 Type: Proceedings Paper","","","","open source; software supply chain; knowledge flow; risk management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the highly distributed and dynamic nature of OSS development, it is often described in unitary, monolithic terms - an unfortunate situation which masks considerable variance across OSS development processes. Therefore we explore reasons for systematic variance in these processes so as to enable more effective OSS development practices. Drawing on theory of distributed cognition, we develop a language of cognitive translations, which occur within and across distributed social arrangements and structural conditions of sharing knowledge. This language provides micro-foundations for understanding how different modes of OSS development emerge. Through examining how generative characteristics of social and structural distributions in OSS shape distinct development pathways, we propose a theoretically derived typology explaining the characteristics, dynamics, and conditions for success of different modes of OSS development.","2014","2025-04-25 15:53:57","2025-04-25 15:53:57","","4568-4577","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Univ Hawaii, Shidler Coll Business; IEEE Comp Soc ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Comparing to traditional software engineering approach, we found this approach is absolutely reversed. Open source development and delivery occurs on Internet time. Developers are not confined to a geographic area. They work voluntarily on a project of their choice; they are not forced to join a particular project just because it needs more developers or the project has a high degree of urgency. Developers work for peer-recognition and self-satisfaction. In the open source community, each and every project has an equal priority. Software designed under open source is not released until the project owner thinks that the software has reached a functional stage. One of the success stories is the Linux operating system. Open Source software is always in an evolutionary stage: it never reaches a final stage. As new requirements emerge the software is enhanced by the user/developers. In this paper, we give an introduction to the insights of open source software development. We then elucidate the perceived benefits and point out the differences between open source and closed source software development approaches. At the end we propose a new model for open source software development.","2003","2025-04-25 15:53:57","2025-04-25 15:53:57","","136-143","","","","","","","","","","","INT INST INFORMATICS & SYSTEMICS","14269 LORD BARCLAY DR, ORLANDO, FL 32837 USA","English","","","","","","","Backup Publisher: Int Inst Informat & System Type: Proceedings Paper","","","","","","Callaos, N; Lesso, W; Schewe, KD; Atlam, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects. (C) 2013 Elsevier B.V.

Accordingly, various articles in the literature assess the quality and success of OSS, by using different quality attributes and metrics and different approaches. Though this variety can be considered as a positive indicator of research interest and maturation on one side, it creates a kind of jungle in defining and understanding the terms `quality' and `success' on the other side. Based on this challenge, in this study, we targeted a systematic mapping (SM) of the articles on quality and success of OSS. More than 474 articles have appeared in this area between the years 2002 and 2017, and the final pool of 128 articles is obtained by defining and applying inclusion and exclusion criteria. SM was employed to develop a classification scheme and categorized the existing body of articles with respect to five research questions (RQs) on: contribution and research types, quality criteria and metrics, success criteria and metrics, the relation of quality and success, and demographics. We observed that the majority of the articles assess the concept of quality as `code quality', whereas the concept of success is mostly perceived as `market success' and/or `developer activity'. Moreover, the metrics of `contributing developers/users', and the quality attribute of `functionality' are the quality criteria most employed in the assessment of success.","2019","2025-04-25 15:53:57","2025-04-25 15:53:57","","363-370","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","open source; OSS; software metrics; success; software; quality; systematic mapping","","Staron, M; Capilla, R; Skavhaug, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (Von Hippel and Von Krogh, 2003, 2006), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that - (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described. (C) 2013 Elsevier B.V.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. Design/methodology/approach - The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. Findings - The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain. Last, but not least, it blurs the boundary between development and use, since the developer remains the key user. Research limitations/implications - The paper addresses the implications for future research in the area. Practical implications - The paper addresses implications for practitioners directly involved in innovation and product development. Originality/value - This paper develops a conceptual framework for understanding product development based on non-proprietary knowledge, which cannot be adequately accounted for by traditional corporate innovation theory alone.","2008","2025-04-25 15:53:57","2025-04-25 15:53:57","","142+","","1","11","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Innovation; Resource management; Communication technologies; Internet; Open systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lockin, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-04-25 15:53:57","2025-04-25 15:53:57","","7-12","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives-voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study I investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.

For loosely coupled forms of organization, such as open source systems (OSS) development projects, there are very few approaches to ensure the quality of project reporting; a promising approach can be to augment human reporting with data analysis based on the communication and state changes in an OSS project. In this paper we propose a concept and an initial measurement approach for event-based monitoring of OSS projects to better understand the actual benefit of tool-supported gathering, correlating and analyzing processes event data from the OSS community as a supplement for traditional software project monitoring data collection.

For the solution of the two-dimensional flow field, the k-omega SST and Langtry-Menter Transition SST (gamma-(R) over tildee theta(t)) turbulence models were employed, while the Transition SST (gamma-(R) over tildee theta(t)) model was used for three-dimensional analyses. All simulations were time-dependent and solved using pimpleCentralFoam, a pressure-based, semi-implicit hybrid solver. The obtained data were compared with experimental results and examined in detail. The findings revealed that the hybrid solver used, combined with the Transition SST (gamma-(R) over tildee theta(t)) turbulence model-frequently preferred for modeling transition to turbulence-worked efficiently together and produced results closely aligned with experimental data.

The traditional market failure argument suggests that innovation is characterized by high investment and low copy cost, and firms have difficulty in internalizing the fruits of their innovative effort. Thus, technology firms are seeking more patents, expanding their scope and overhauling their business models around intellectual property. Yet paradoxically, with the progress and development of information technology, open source software (OSS) plays an important role in expanding enterprise informatization. For example, Linux is developed quickly by this open way. Some firms have found the ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is one example. In this article, the author introduces a model of OSS based on its network effects to understand how the enterprises decide their activities in this open market competition. This article describes the inherent reasons of open source movement from the view of the oligopoly structure. At the same time, this article analyses the effect of leader enterprise and follower enterprise on market structure and the different activities of these enterprises after the source has been opened. Finally, we make suggestions that companies at the leading edge are often in such a strong position that they do need the support of down-streams companies to broaden their technologies successfully and to decrease their risks in order to leverage the value of the technological portfolio. On the other hand, this article suggests that follower enterprises have incentive to take part in the development of open-source software only when the market has grown up.","2008","2025-04-25 15:53:58","2025-04-25 15:53:58","","669+","","","254","","","","International Federation for Information Processing","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","ISSN: 1571-5736 Type: Proceedings Paper","","","","open source software; enterprise normalization; OSS model","","Xu, LD; Tjoa, AM; Chaudhry, SS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Over time, organizations face the OSS adoption challenge strengthening mainly its internal and technical elements. However, the rapid changes on business dynamics, and the comprehensiveness and fast development of open paradigms, show us that a new set of conditions must be satisfied to reach a successfully OSS adoption. These conditions, considered as a critical success factors, involve a wide range of resources, capacities and skills, both in internal and external scopes. Hence, although adopter organizations should be better prepared to face the challenges related to collaborative innovation, they do not have a systematic approach to value its readiness level to face the adoption challenges. In this context, the present research work proposes a model to assess the organizational readiness, considering the adopter as part of a live business ecosystem, where the relationships originated on co-development with developers' communities, have mutual business impact at strategic, tactic, and operative level.","2021","2025-04-25 15:53:59","2025-04-25 15:53:59","","800-807","","","","","","","","","","","SCITEPRESS","AV D MANUELL, 27A 2 ESQ, SETUBAL, 2910-595, PORTUGAL","English","","","","","","","Backup Publisher: INSTICC Type: Proceedings Paper","","","","Open Source Software Adoption; Open Innovation; Organizational Readiness Assessment","","Filipe, J; Smialek, M; Brodsky, A; Hammoudi, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey.

In this article we argue that disadvantage is more due to gendered behavior than to categorical discrimination: women are at a disadvantage because of what they do, rather than because of who they are. Using data on entire careers of users from GitHub.com, we develop a measure to capture the gendered pattern of behavior: We use a random forest prediction of being female (as opposed to being male) by behavioral choices in the level of activity, specialization in programming languages, and choice of partners. We test differences in success and survival along both categorical gender and the gendered pattern of behavior. We find that 84.5% of women's disadvantage (compared to men) in success and 34.8% of their disadvantage in survival are due to the female pattern of their behavior. Men are also disadvantaged along their interquartile range of the female pattern of their behavior, and users who don't reveal their gender suffer an even more drastic disadvantage in survival probability. Moreover, we do not see evidence for any reduction of these inequalities in time. Our findings are robust to noise in gender recognition, and to taking into account particular programming languages, or decision tree classes of gendered behavior. Our results suggest that fighting categorical gender discrimination will have a limited impact on gender inequalities in open source software development, and that gender hiding is not a viable strategy for women.","2019-07-06","2025-04-25 15:53:59","2025-04-25 15:53:59","","","","","8","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Open source; Software development; Gender inequality; Gendered behavior","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

However, there has been limited research on developers' abandonment, though it is found to have detrimental effect on quality and sustainability of OSS projects. This paper examines the impact of developer and project-related factors on developer abandonment in OSS projects. Factors include developer attributes: experience, role, coding language, and joining date, and project attributes: change complexity and sentiments in commit logs.

However, newcomers face many barriers when making their first contribution, leading in many cases to dropouts. Due to the collaborative nature of community-based OSS projects, newcomers may be susceptible to social barriers, such as communication breakdowns and reception issues. In this article, we report a two-phase study aimed at better understanding social barriers faced by newcomers. In the first phase, we qualitatively analyzed the literature and data collected from practitioners to identify barriers that hinder newcomers' first contribution. We designed a model composed of 58 barriers, including 13 social barriers. In the second phase, based on the barriers model, we developed FLOSScoach, a portal to support newcomers making their first contribution. We evaluated the portal in a diary-based study and found that the portal guided the newcomers and reduced the need for communication. Our results provide insights for communities that want to support newcomers and lay a foundation for building better onboarding tools. The contributions of this paper include identifying and gathering empirical evidence of social barriers faced by newcomers; understanding how social barriers can be reduced or avoided by using a portal that organizes proper information for newcomers (FLOSScoach); presenting guidelines for communities and newcomers on how to reduce or avoid social barriers; and identifying new streams of research.","2019-04","2025-04-25 15:53:59","2025-04-25 15:53:59","","247-290","","1-2","28","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Joining; Newcomers; Onboarding; Open source software; Online communities; FLOSS; Socialization; Challenges; Difficulties; Beginners; Entry; New contributor; Newbies; Qualitative study; Social barriers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Especially in the higher education sector, IT is playing a vital role in the advancement of teaching and learning practices. Most of the educational organizations have already adopted smart learning environment by upgrading their infrastructure and with proper capacity building among staff members. But in the education sector, sustainability of technology is always being a challenge. To develop learning materials, many institutions have already started using free and open source software (FOSS) tools. FOSS gives freedom to the developer with the provision of various customization options as per the requirements of the class or subject. Moreover, in the longer run, free and open source software could be considered as the best option in education for e-learning implementation, for sustainability. There are many tools which are available for e-learning resource development. Some of them are available online and some are available as an installer for the various platform. In order to adapt ICT in education, especially in non-IT specialization, the faculty members need the training to learn and implement these tools in their classes. But there are many tools, which are specially designed for educators with basic knowledge of computers. Educators can plan their sessions, based on content, duration as well as the level of the subject and the students. This research paper will highlight various aspects of the implementation of FOSS, in education by using such easy-to-implement tools and techniques. This would provide general guidelines for the development of various e-learning solutions for technology-enhanced teaching and learning practices in higher education.","2017","2025-04-25 15:53:59","2025-04-25 15:53:59","","1075-1079","","","","","","","","","","","INT ORGANIZATION CENTER ACAD RESEARCH","YUNUS EMRE CAD AKASYA SK NO 22, UGUR MUMCU, ISTANBUL, KARTAL 00000, TURKEY","English","","","","","","","Backup Publisher: Int Org Ctr Acad Res Type: Proceedings Paper","","","","Free and open source software; E-learning; Enhanced teaching and learning practices; Interactive educational tools; Multimedia in education; Sustainability in education; Technology-enhanced learning","","Uslu, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Communications and collaborations are essential for the success of projects. Usually, the most active and productive programmers are awarded with promotion to developers. To more effectively manage and progress the projects, it is important and beneficial to rank the programmers and thus, predict the developer candidates. In this work, we propose to combine machine learning techniques with existing complex network node ranking algorithms to improve the prediction results. Specifically, we have made the following contributions: (1), we have designed a novel machine learning-based classifier with significantly improved prediction performance; (2), we have constructed and tested various networks built based on the programmer email communication information; and (3), we have used real-world project data to compare different techniques and validate our methods. Experimental results demonstrate that our technique reduces the error rate by 25% compared with the second best. Moreover, we discover that the KK nearest neighbor (KNN)-based machine learning algorithm and non-directional temporal network with a time window of 1-3 months give the best prediction results.","2018-06","2025-04-25 15:53:59","2025-04-25 15:53:59","","845-868","","6","28","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","machine learning; Open source software; complex network; ranking algorithm","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Altmetrics cannot be confined to traditional measurable indicators. That the importance of the open source software used, and its position in the online community is itself a strong measure for academic impact and success, which is all too often overlooked in research. The research can also conclude that the multiplexing of software online, through the citation of a citation, ultimately leads to an online peered review system within the community, effectively developing and maintaining through open use software itself.

In 2005, several university libraries, university college libraries and other research libraries met and discussed a joint effort to create institutional archives. The meeting resulted in the Pepia project with BIBSYS as a software partner. The project group decided to use the open source system DSpace as a software platform. A standard DSpace installation runs on a Tomcat servlet container. BIBSYS does not use this container, and we therefore needed to configure DSpace to get it to run successfully on our server. In addition we had some problems with integrating the DSpace development structure with our integrated development environment. Further we needed to create a new build process that effectively could build more than 30 applications from one source code. These changes were quite time consuming, but they were necessary so that we could have an efficient work environment. Out of the box DSpace has many of the functionalities that an institutional archive requires. In spite of this we needed to alter some of the functionality, especially the user management system. DSpace is a complex system, but with the active community we could get the help we needed. BIBSYS Brage, the result of the Pepia project, was launched as a beta version in December 2006. We look forward to develop BIBSYS Brage further, and are confidant that it will become a great system for the consortium.","2007-12","2025-04-25 15:53:59","2025-04-25 15:53:59","","","","19","","","","","","","","","","","English","","","","","","","Place: C ADOLF FLORENSA S-N, BARCELONA, 08028, SPAIN Publisher: UNIV BARCELONA, SERVEI PUBLICACIONS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To detect such vulnerabilities, finding OSS reuses in COTS software has become imperative. While scalable to tens of thousands of OSS projects, existing binary-to-source matching approaches are severely imprecise in analyzing COTS software products, since they support only a limited number of code features, compute matching scores only approximately in measuring OSS reuses, and neglect the code structures in OSS projects. We introduce a novel binary-to-source matching approach, called B2SFINDER1, to address these limitations. First of all, B2SFINDER can reason about seven kinds of code features that are traceable in both binary and source code. In order to compute matching scores precisely, B2SFINDER employs a weighted feature matching algorithm that combines three matching methods (for dealing with different code features) with two importance-weighting methods (for computing the weight of an instance of a code feature in a given COTS software application based on its specificity and occurrence frequency). Finally, B2SFINDER identifies different types of code reuses based on matching scores and code structures of OSS projects. We have implemented B2SFINDER using an optimized data structure. We have evaluated B2SFINDER using 21991 binaries from 1000 popular COTS software products and 2189 candidate OSS projects. Our experimental results show that B2SFINDER is not only precise but also scalable. Compared with the state of the art, B2SFINDER has successfully found up to 2.15x as many reuse cases in 53.85 seconds per binary file on average. We also discuss how B2SFINDER can be leveraged in detecting OSS reuse vulnerabilities in practice.","2019","2025-04-25 15:53:59","2025-04-25 15:53:59","","1038-1049","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Comp Soc Tech Council Software Engn; ACM Special Interest Grp Artificial Intelligence; ACM Special Interest Grp Software Engn Type: Proceedings Paper","","","","OSS; Code Reuse; Binary-to-Source Matching; Code Feature; COTS Software; One-Day Vulnerability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This process is reviewed and illustrated with OsiriX, a fast DICOM viewer program for the Apple Macintosh. Materials and methods OsiriX is an oss for the Apple Macintosh under Mac OS X v10.4 or higher specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: multiplanar reconstruction, surface rendering, volume rendering and maximum Intensity projection. All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT). OsiriX was developed using the Apple Xcode development environment and Cocoa framework as both a DICOM PACS workstation for medical imaging and an image processing software package for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging. Results OsiriX is an open source program by Antoine Rosset, a radiologist and software developer, was designed specifically for the needs of advanced imaging modalities. The software program turns an Apple Macintosh into a DICOM PACS workstation for medical imaging and image processing. OsiriX is distributed free of charge under the GNU General Public License and its source code is available to anyone. This system illustrates how open software development for medical imaging tools can be successfully designed, implemented and disseminated. Conclusion oss development can provide useful cost effective tools tailored to specific needs and clinical tasks. The integrity and quality assurance of open software developed by a community of users does not follow the traditional conformance and certification required for commercial medical software programs. However, open software can lead to innovative solutions designed by users better suited for specific tasks.","2006-12","2025-04-25 15:53:59","2025-04-25 15:53:59","","187-196","","4","1","","","","","","","","","","English","","","","","","","Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors' learning processes is an important research area in OSS. This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education.

Maintenance effort is usually measured in person-hours used to perform a maintenance task. However, maintenance effort data are usually only available for strictly managed software, such as closed-source software. In other software projects that do not have complete maintenance records, especially some open-source software, there are no direct data for maintenance effort, which precludes the establishment of a maintenance effort model. In this paper, we report a series of studies aimed at presenting a method for indirectly predicting the maintenance effort of open-source software. This report covers two parts of our research. First, we examine the maintenance data from NASA SEL closed-source software projects and identify some software measures that can be used to indirectly represent maintenance effort. Second, based on the findings in the first part, we analyze 121 recent versions of Linux, and use linear regression to construct two indirect maintenance effort models for the Linux project. Our study demonstrates the applicability of this approach to indirectly predicting the maintenance effort and improving the software maintenance process.

These challenges of understanding and evolving existing code can be illustrated in academic settings by leveraging the rich and varied volume of Open Source Software (OSS) code. To teach SE with OSS, however, it is necessary to select uniform projects of appropriate size and complexity. This paper reports on our search for suitable OSS projects to teach an introductory SE course with a focus on maintenance and evolution.

It is growing in popularity, which has brought about an increase in research interest. Most of the research studies have focused on identifying individual personal motives for participating in the development of an OSS project, analyzing specific solutions, or the OSS movement, itself. No studies have been found which have undertaken research on the impact of user experience and training on OSS. The study reported here sought to identify factors that predict acceptance of technologies based on OSS after training in these solutions. A research model based on the Technology Acceptance Model (Davis, 1989) was developed. Furthermore, the possible moderating effects of users' gender, age and level of education were analyzed. It was found that external determinants such as user training, user fit, technological complexity and trainers' support were important indicators in the success of adopting these solutions.

Open Source Software (OSS) has becoming widely adopted by commercial, public and academic organisations. Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world! OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization's success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems. The main aim of this paper is to measure the evolution of OSS using, Eclipse Metrics (EM), with Guice software (GS) as a case study. In addition, this paper gives a brief literature review on OSS and how it has evolved.","2009","2025-04-25 15:54:00","2025-04-25 15:54:00","","211-218","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context. Can rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 15:54:00","2025-04-25 15:54:00","","1449-1469","","4","63","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","OSS; Open-source software; Entrepreneurship; Trust; Crowdfunding; L26; O30; O34; O36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the discrete modeling framework has been proposed to study the reliability growth process of OSS systems with multiple releases. The proposed model is based upon the assumption that during up-gradation some new faults are introduced in the code in addition to the left over fault content of the previous version. To validate our model, we have chosen two successful open source projects-Mozilla and Apache for its multi release failure datasets. Graphs representing goodness of fit of the proposed model have been drawn. The parameter estimates and measures of goodness of fit criteria suggest that the proposed software reliability growth model for multi-release OSS fits the actual datasets very well. An optimal release policy has been formulated by taking into account the cost of fault removal during testing and operational phases and reliability targets pre-specified by the decision makers. In addition, numerical example along with the sensitivity analysis has been provided to illustrate optimal release policy.","2018-04","2025-04-25 15:54:00","2025-04-25 15:54:00","","","","2","15","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","Open source software; discrete software reliability growth model; fault removal process; multi-release software system; release time","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

These communities' survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSScoach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process. However, there is also some indication that FLOSScoach did not lower the technical barriers.","2015","2025-04-25 15:54:01","2025-04-25 15:54:01","","160-169","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: ThoughtWorks; AvenueCode; Google; take.net; RARO Labs; Avanti; IBM; CNPq; CAPES; FAPEMIG; UFmG; PUC Minas; CEFET MG Type: Proceedings Paper","","","","open source; newcomers; onboarding; contribution barriers; self-efficacy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Yet, newcomers face a steep learning curve during OSS onboarding in which they must overcome a multitude of technical, social, and knowledge barriers. To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., “good first issues”), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.","2023","2025-04-25 15:54:01","2025-04-25 15:54:01","","324-336","","","","","","","International Conference on Software Engineering-Software Engineering Education and Training","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISSN: 2832-756X Type: Proceedings Paper","","","","open source software; open source onboarding; software engineering education","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as “joiners”) can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.","2011-01","2025-04-25 15:54:02","2025-04-25 15:54:02","","208-238","","1","14","","","","","","","","","","English","","","","","","","Place: 2455 ℡LER RD, THOUSAND OAKS, CA 91320 USA Publisher: SAGE PUBLICATIONS INC Type: Article","","","","latent class analysis; latent class growth models; latent growth models; longitudinal data analysis; quantitative: structural equation modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The culture and norms of FLOSS appear to be formulated by what is privileged/marginalized by men in the context of FLOSS, and such men's valuing is likely to threaten women FLOSS participants' face. Our findings are 1) in the FLOSS context, there are gender-based differences in determining what threatens face on the basis of gendered expectations of what is polite, and 2) women-dominated FLOSS participants are “practically” polite in software development practices. These findings were explored through an in-depth analysis of interaction episodes on the email list, archival public interview data of women FLOSS developers, FLOSS development environment, and instructive materials shared in public. Our paper shows how politeness theory can be extended to the “practice” of coding and non-coding work, and provides FLOSS communities with guidelines for involving and sustaining women participants in FLOSS development.","2013","2025-04-25 15:54:02","2025-04-25 15:54:02","","3168-3177","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc; Univ Hawaii, Shidler Coll Business ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the impacts of microblogging follower network on OSS project success are rarely studied. In this study, we adopt a social network perspective to identify and hypothesize that three microblogging network mechanisms will positively affect OSS project success through knowledge sharing, and attracting more skillful and eminent developers. Using longitudinal data from a large online OSS community called Ohloh, we empirically examine the impacts of various factors for these two type of mechanisms on the commercial and technological successes of OSS projects. We found that preferential attachment and structure hole factors are supported, while accumulative advantage factors are partially supported. Our findings may provide insights for OSS stakeholders to effectively manage microblogging techniques for achieving project success.","2013","2025-04-25 15:54:02","2025-04-25 15:54:02","","3178-3186","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc; Univ Hawaii, Shidler Coll Business ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because students are accustomed to gathering information using commercial search engines, they can overlook high-quality library resources. To connect with student researchers when they need library resources, many libraries have built online research guides tied to specific subjects and courses. These guides can address specific assignments where research is required, and course instructors can point students to the guides to assist them in completing their research assignments successfully. In 2006, Oregon State University (OSU) Libraries developed an open source software product called Library a la Carte that librarians can use to construct research guides easily and quickly. The code was made available to other libraries, and a number of institutions have adopted the tool. A successful user community has grown up around Library a la Carte, but development up to this point has been the sole responsibility of OSU Libraries. We are now embarking on building a robust developer community, to contribute code, to build additional features and to take Library a la Carte into the future. As part of our plan to move forward, we are testing a hosted (cloud-based) version of the software. This paper introduces Library a la Carte, presents what was learned from the test and discusses moving forward with building a developer community. In addition, we touch on the benefits and challenges of building and sustaining an open source product from the ground up.","2012","2025-04-25 15:54:02","2025-04-25 15:54:02","","6471-6476","","","","","","","INTED Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION A& DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1079 Type: Proceedings Paper","","","","open source software; cloud computing; libraries; library guides","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper investigates the contribution of Free/Libre Open-Source Software (FLOSS) towards fair, and conflict-free practices through promoting collaboration, transparency, and resource accessibility. Our study investigates how the adoption of decentralized online social networks (DOSN) like Mastodon (microblogging) and PeerTube (video sharing), which operate on the ActivityPub protocol, contributes to sustainable practices within the electronics sector by fostering a federated universe (Fediverse). It is demonstrated how FLOSS, in the form of Alternative Mobile Operating Systems (AMOS) including Android open-source custom ROMs or mobile Linux systems, gain traction due to enhanced privacy protection, improved usability through tracker-free software and alternative app stores, and adherence to EU directives on the right to self-repair. As AMOS mature for everyday use, they attract consumers, thereby contributing towards sustainable electronics development. Furthermore, the Fediverse's Application Programming Interfaces (APIs) enable seamless information exchange between instances, allowing for nuanced moderation that safeguards user privacy. This approach contrasts with centralized commercial networks, where algorithm-driven operations often prioritize profit over user well-being.","2024","2025-04-25 15:54:02","2025-04-25 15:54:02","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","","","FLOSS; sustainability; Fediverse; alternative mobile operating systems (AMOS); decentralized","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The overall success of peer code review, commonly used in open source projects, has likely contributed strongly to this success. Code review is an emotionally loaded practice, with public exposure of reputation and ample opportunities for conflict. We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process. It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market. In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-04-25 15:54:03","2025-04-25 15:54:03","","1073-1083","","","","","","","International Conference on Software Engineering","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE Comp Soc, Tech Comm Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","Motivation; Open Source; Code Review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study shows that open source software has certain facets; code, community, coordination mechanisms, license and documentation. Each facet is not stable; indeed, it is changing and mutable. This creates possibilities, potential but also recalcitrance, and barriers. The interesting point of departure of our study is how open source software a much touted transparent and open phenomenon is by its nuanced and layered mutability able to make the process and practices surrounding it less visible.

National user groups can bolster these international communities by convening local events, championing the software to peers, welcoming and onboarding new contributors, raising money to support the broader community, and collecting important information on user's needs. The open source community-led software DSpace has had great success encouraging the creation of national user groups; in the UK, North America, and Germany, the Groups have been active for many years. However, it was in 2018, thanks to a renewed focus on international engagement and more diverse representation of the global community in governance groups, that the national communities entered into a new phase: 15 new national User Groups have been formed all over the world since then, while the German user group evolved into the “DSpace-Konsortium Deutschland”, founded by 25 institutions, marking a pivotal point for membership options and National User Group participation within DSpace Governance.

In GitHub, developers are allowed to fork repositories and copy repositories without asking for permission, which make contribution to projects much easier than it has ever been. It is significant to predict the number of forks for open source software projects. The prediction can help GitHub to recommend popular projects, and guide developers to find projects which are likely to succeed and worthy of their contribution. In this paper, we use stepwise regression and design a model to predict the number of forks for open source software projects. Then we collect datasets of 1,000 repositories through GitHub's APIs. We use datasets of 700 repositories to compute the weight of attributes and realize the model. Then we use other 300 repositories to verify the prediction accuracy of our model. Advantages of our model include: (1) Some attributes used in our model are new. This is because GitHub is different from traditional open source software platforms and has some new features. These new features are used to build our model. (2) Our model uses project information within t month after its creation, and predicts the number of forks in the month T (t < T). It allows users to set the combination of time parameters and satisfy their own needs. (3) Our model predicts the exact number of forks, rather than the range of the number of forks (4) Experiments show that our model has high prediction accuracy. For example, we use project information with 3 months to prediction the number of forks in month 6 after its creation. The correlation coefficient is as high as 0.992, and the median number of absolute difference between prediction value and actual value is only 1.8. It shows that the predicted number of forks is very close to the actual number of forks. Our model also has high prediction accuracy when we set other time parameters.","2014","2025-04-25 15:54:03","2025-04-25 15:54:03","","40-47","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Type: Proceedings Paper","","","","Open Source Software; Fork","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The potential for sustainability of such tools needs to assessed prior to any organisational adoption. In this paper we report from a case study conducted in a consultancy company context aiming to investigate Open Source tools for MDD. For the company it was interesting to explore the two Open Source modelling tools Topcased and Papyrus for potential adoption. The focus for our case study is on assessing the health of the ecosystems for the two investigated Open Source projects by means of quantitative analysis of publically available data sources about Open Source projects. The health of ecosystems is an important prerequisite for a long term sustainable OSS (Open Source Software) tool-chain in the MDD area, which can aid strategic decision making for potential adoption within a company context. We have established details on the extent to which developers and users are active in two specific OSS ecosystems, and identified organisational influence for both ecosystems.

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making `good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.","2009","2025-04-25 15:54:03","2025-04-25 15:54:03","","51-71","","1","74","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","ethics; Software; freedom; progress; social form","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some countries have successfully created extensive information technology infrastructures, yet software use continues to be reliant on pirated sources. The experiences of licensing regulation violations and increasing virus attacks indicate that part of the problem is a consequence of dependencies created by the use of proprietary software within resourcescarce economies. Recent growth in the use of free and open-source software (FOSS) by various public-and private-sector agencies suggests an alternative path to software self-suffciency for a resource-scarce country like Cuba. There is, however, an interesting background to current software use within Cuba that makes it unique among several less-developed countries. Apart from the well-known advantages, FOSS use could be essential to shape the future scenario of Cuba. The present paper first delineates some of the Cuban background, basically characterized by lack of freedom in technology ownership and access to external information. The potential of FOSS use within existing conditions in Cuba is then analyzed. Finally, conclusions are provided on the basis of a survey carried out in Cuba, arguing that there needs to be stronger political will to reduce gaps between goals and implementation reality to achieve intrinsic advantages of FOSS use successfully.","2006","2025-04-25 15:54:03","2025-04-25 15:54:03","","1-17","","1","3","","","","","","","","","","English","","","","","","","Place: UNIV SOUTHERN CALIFORNIA, KERCKHOFF HALL, 734 W ADAMS BLVD, MC7725, LOS ANGELES, CA 90089 USA Publisher: USC ANNENBERG PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various authors have made research in this direction by applying different techniques in order to improve the reliability of open source software projects. In this work, an various machine learning models have been implemented to examine the reliability of the software.

Having tried both ways allows us to retrospectively; compare the effectiveness of “from scratch” implementation versus software evolution. By using the code bases of GNU GCC and Linux for the adaptation approach we gained valuable experiences with the comprehension and adaptation of large but sparsely documented code bases. In most cases, the adaptation of existing software proved to be by-far more effective than implementing from scratch. Surprisingly, the effort needed to comprehend the existing voluminous source codes repeatedly proved to be less than expected.

Against conventional wisdom this approach has been wildly successful in the general software market-probably because the openness lets programmers the world over obtain, critique, use, and build upon the source code without licensing fees. Linux, a UNIX-like operating system, is the best known success. But computer scientists at the University of California, Berkeley began the tradition of software sharing in the mid 1970s with BSD UNIX and distributed the major internet network protocols as source code without a fee. Medical informatics has its own history of Open Source distribution: Massachusetts General's COSTAR and the Veterans Administration's VISTA software have been distributed as source code at no cost for decades. Bioinformatics, our sister field, has embraced the Open Source movement and developed rich libraries of open-source software. Open Source has now gained a tiny foothold in health care (OSCAR GEHR, OpenEMed). Medical informatics researchers and funding agencies should support and nurture this movement. In a world where open-source modules were integrated into operational health care systems, informatics researchers would have real world niches into which they could engraft and test their software inventions. This could produce a burst of innovation that would help solve the many problems of the health care system.

To this end, we contribute a process for decomposing trust in a complex large-scale system into key trust relationships, systematically identifying behavior-based indicators for the components of trust for a given relationship, and in turn operationalizing data-driven metrics for those indicators, allowing for the wide-scale measurement of trust in practice.","2024","2025-04-25 15:54:04","2025-04-25 15:54:04","","57-61","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite many failures in these projects, there are some success stories with one of the identified success factors is modularity. This paper presents the first quantitative software metrics to measure modularity level of Java-based OSS Projects called Modularity Index. This software metrics is formulated by analyzing modularity traits such as size, complexity, cohesion, and coupling of 59 Java-based OSS Projects from sourceforge. net using SONAR tool. These OSS Projects are selected since they have been downloaded more than 100K times and believed to have the required modularity trait to be successful. The software metrics related to modularity in class, package and system level of these projects are extracted and analyzed. The similarities found are then analyzed to determine the class quality, package quality, and then combined with system architecture measure to formulate the Modularity Index. The case study of measuring Modularity Index during the evolution of JFreeChart project has shown that this software metrics is able to identify strengths and potential problems of the project.","2011-11","2025-04-25 15:54:04","2025-04-25 15:54:04","","52-58","","11","2","","","","","","","","","","English","","","","","","","Place: 19 BOLLING RD, BRADFORD, WEST YORKSHIRE, 00000, ENGLAND Publisher: SCIENCE & INFORMATION SAI ORGANIZATION LTD Type: Article","","","","software metrics; modularity; Java; Open source software projects; sourceforge; system architecture","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is growing rapidly and gaining market share in both industry (e. g., Linux and Mozilla) as well as academia (e.g, Moodle, Greenfoot, and Drupal). OSS projects have a culture built on volunteer participation to support software development. Computing degree programs desire to involve students in large-scale software projects to provide students with real-world experience and an understanding of the issues found in large, complex software projects. Involving computing students in OSS projects serves both the OSS community by providing development resources for the project while also serving the academic community by providing access to large software projects in which students can gain experience. However, the marriage of student and OSS project presents some challenges including identification of approachable OSS projects, creation of appropriate educational infrastructure, evaluation and grading, and more.

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer. Finally, we develop a committer-identification model to assist OSS projects identifying future committers.","2014","2025-04-25 15:54:04","2025-04-25 15:54:04","","47-56","","","","","","","International Conference on Quality Software","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Reliabil Soc; UT Dallas; IEEE Comp Soc ISSN: 1550-6002 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the energy sector has not yet embraced open-source software to the same level. We discuss how existing open-source software principles can be applied to the unique challenges of the energy sector during the transition towards higher penetration of renewable energy resources. To provide an overview of the current state of the open-source software landscape, we collected and analyzed 388 open-source projects, in terms of project activities, community composition, relevant licenses, and commonly used programming languages.

However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma, allowing for early diagnosis and intervention. We have developed Specvis, a free and open-source application written in Java programming language that can run on any personal computer to meet this requirement (http://www. specvis. pl/). Specvis was tested on glaucomatous, retinitis pigmentosa and stroke patients and the results were compared to results using the Medmont M700 Automated Static Perimeter. The application was also tested for inter-test intrapersonal variability. The results from both validation studies indicated low inter-test intrapersonal variability, and suitable reliability for a fast and simple assessment of visual field impairment. Specvis easily identifies visual field areas of zero sensitivity and allows for evaluation of its levels throughout the visual field. Thus, Specvis is a new, reliable application that can be successfully used for visual field examination and can fill the gap between confrontation and perimetry tests. The main advantages of Specvis over existing methods are its availability (free), affordability (runs on any personal computer), and reliability (comparable to high-cost solutions).","2017-10-13","2025-04-25 15:54:05","2025-04-25 15:54:05","","","","10","12","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the same time, we draw on Mobley's model of withdrawal decision process to hypothesize the relationship between dissatisfaction and perceived turnover. We develop a research model and present hypotheses that should be tested in the future.

Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them.

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg's motivation-hygiene framework, we explore how developers' perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022","2025-04-25 15:54:05","2025-04-25 15:54:05","","165-195","","1","23","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","Motivation; Open Source Software; Change Over Time; Code Contribution; Multilevel Growth Analysis; Payment; Value Fit","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Similarly, testability is a residual software property which the developers and users no longer ignore. This is because if the testability of software is high, the test effort and development cost decrease proportionally. This is the case because test effort is highly affected by testability. In this paper, we investigate the relationship between test effort and success of the open source software by employing source codes and easily accessible parameters from the repository. Moreover, the proposed methods are empirically examined by analyzing 17 open source software projects. According to the empirical results, a meaningful positive correlation is obtained between test effort and success. This implies the importance of preparing test scenarios and codes to obtain successful open source software project.","2019","2025-04-25 15:54:06","2025-04-25 15:54:06","","688-692","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","Turkish","","","","","","","Backup Publisher: IEEE; IEEE Turkey Sect Type: Proceedings Paper","","","","Open Source Software; Success; Software Quality; Test Effort","","Adali, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

Consequently, support in the exchange of data, information, and knowledge is becoming the key issue in computer technology today. The increasing volume of data available on the Web makes information retrieval a tedious and difficult task. Researchers are now exploring the possibility of creating a semantic web, in which meaning is made explicit, allowing machines to process and integrate web resources intelligently. The vision of the semantic web introduces the next generation of the Web by establishing a layer of machine-understandable data. The success of the semantic web depends on the easy creation, integration and use of semantic data, which will depend on web ontology. The faceted approach towards analyzing and representing knowledge given by S R Ranganathan would be useful in this regard. Ontology development in different fields is one such area where this approach given by Ranganathan could be applied.

There are many open-source architecture frameworks for UAS that claim the autonomous operation of UAS, but they still have two main open issues: (1) level of autonomy, being in most of the cases limited and (2) versatility, being most of them designed specifically for some applications or aerial platforms. As a response to these needs and issues, this paper presents Aerostack, a system architecture and open-source multi-purpose software framework for autonomous multi-UAS operation. To provide higher degrees of autonomy, Aerostack's system architecture integrates state of the art concepts of intelligent, cognitive and social robotics, based on five layers: reactive, executive, deliberative, reflective, and social. To be a highly versatile practical solution, Aerostack's open-source software framework includes the main components to execute the architecture for fully autonomous missions of swarms of UAS; a collection of ready-to-use and flight proven modular components that can be reused by the users and developers; and compatibility with five well known aerial platforms, as well as a high number of sensors. Aerostack has been validated during three years by its successful use on many research projects, international competitions and exhibitions. To corroborate this fact, this paper also presents Aerostack carrying out a fictional fully autonomous indoors search and rescue mission.","2016","2025-04-25 15:54:06","2025-04-25 15:54:06","","332-341","","","","","","","International Conference on Unmanned Aircraft Systems","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Robot & Automat Soc; IEEE CSS; MCA ISSN: 2373-6720 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These efforts aim to identify common elements in the development process between multiple open source software (OSS) projects. However, the complexity inherent to OSSD process modeling puts significant demands on the modeling language. Objective: In this paper, we propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. Method: We investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. DEMO models were constructed to describe the NetBeans Requirements and Release process. In addition, the quality of these DEMO models was evaluated using a quality framework for conceptual modeling. Results: Our results showed that our DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. In addition, the evaluation of the models developed in this paper by using the quality framework for conceptual modeling showed that the models were of high quality. Conclusions: We have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models. However, given some potential drawbacks with respect to understandability and implementability, we primarily propose the use of DEMO within OSSD process modeling as an analysis tool that should be complemented with other techniques and models for communication and reenactment purposes.

Despite that a lot of relevant research focusing on this topic, understanding the structures and dynamics of communities around open-source software projects remains a tedious and challenging task. As a result, an easily accessible and useful application that enables project developers to gain awareness of the status and development of the project communities is desirable. In this paper, we present MyCommunity, a web-based online application system to automatically extract communication-based community structures from social coding platforms such as GitHub. Based on the detected community structures, the system analyzes and visualizes the community evolution history of a project with a set of semantic-rich events, and quantify the strength of community evolution with respect to different events with a series of indexes. Built-in support to quantitative analysis and machine learning tasks based on the quantitative evolutionary events are provided. We demonstrate the usefulness of the system by presenting its ability in predicting project success or failure with the community evolution features. The results suggest the system achieves a prediction accuracy of 88.5% with commonly available machine learning models.","2022","2025-04-25 15:54:06","2025-04-25 15:54:06","","38-45","","","13724","","","","Lecture Notes in Computer Science","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","ISSN: 0302-9743 Type: Proceedings Paper","","","","Community evolution; Open source community analysis; Web-based application","","Chbeir, R; Huang, H; Silvestri, F; Manolopoulos, Y; Zhang, Y","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

-"HE4BA4WY","journalArticle","2012","Shanker, Aparna","An Enterprise Perspective on Customer Value Propositions for Open Source Software","TECHNOLOGY INNOVATION MANAGEMENT REVIEW","","1927-0321","","","Research on open source software (OSS) has examined value creation primarily from the perspective of the individuals and suppliers that create the software. The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 15:54:06","2025-04-25 15:54:06","","28-36","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The objective: to explore the evolution of a long-lived open source project with the intention of learning how code evolution has progressed over time. This investigation provides a case study of Nethack, an enormously popular open source game that has been in development for more than a decade. The Goal Question Metric approach was employed to derive measurement goals for the evaluation of open source software (OSS) evolution in Nethack. According to Lehman's laws, the incremental growth size of successive releases tends to decline during the active life of an evolving program. Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased. These findings raise questions concerning the evolution of other OSS applications.","2006","2025-04-25 15:54:06","2025-04-25 15:54:06","","47+","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: NASA Software Engn Lab; NASA Goddard Space Flight Ctr, Informat Syst Div; IEEE Comp Soc, TCSE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The lack of established metrics makes it difficult to formulate such strategy. While many projects have been formed and created, only a few managed to remain active. With the majority of these projects failing, firms need a reliable set of criteria to assess what makes a project appealing not only to developers but also to visitors, users and commercial sponsors. In this paper, we develop a theoretical model to explore the contextual and causal factors of project attractiveness in inducing activities such as source code contribution, software maintenance, and usage. We test our model with data derived from more than 4000 projects spanning 4 years. Our main findings include that projects' set of conditions such as license restrictiveness and their available resources provide the context that directly influence the amount of work activities observed in the projects. It was also found that indirect and unintended contributions such as recommending software, despite of being non-technical, cannot be ignored for project activeness, diffusion and sustainability. Finally, our analysis provide evidence that higher attractiveness leads to more code-related activities with the downside of slowing down responsiveness to address projects' tasks, such as the implementation of new features and bug fixes. Our model underscores the significance of the reinforcing effects of attractiveness and work activities in open source projects, giving us the opportunity to discuss strategies to manage common traps such as the liability of newness. We conclude by discussing the applicability of the research model to other user-led initiatives. (C) 2012 Elsevier B.V.

This study considers if it is possible from an organizational perspective for small to medium-sized cities to provide services and conduct business using only open source software (OSS). We examine characteristics of municipal government that may influence the adoption of OSS for the delivery of services and to conduct city business. Three characteristics are considered to develop an understanding of city behavior with respect to OSS: capability, discipline, and cultural affinity. Each of these general characteristics contributes to the successful adoption and deployment of OSS by cities. Our goal was to determine the organizational characteristics that promote the adoption of OSS. We conducted a survey to support this study resulting in 3316 responses representing 1286 cities in the Unites States and Canada. We found most cities do not have the requisite characteristics to successfully adopt OSS on a comprehensive scale and most cities not currently using OSS have not future plans for OSS.","2009","2025-04-25 15:54:07","2025-04-25 15:54:07","","1044+","","","","","","","Lecture Notes in Engineering and Computer Science","","","","INT ASSOC ENGINEERS-IAENG","UNIT 1, 1-F, 37-39 HUNG TO ROAD, KWUN TONG, HONG KONG, 00000, PEOPLES R CHINA","English","","","","","","","Backup Publisher: IAENG Soc Artificial Intelligence; IAENG Soc Bioinformat; IAENG Soc Comp Sci; IAENG Soc Data Min; IAENG Soc Elect Engn; IAENG Soc Imaging Engn; IAENG Soc Ind Engn; IAENG Soc Internet Comp & Web Serv; IAENG Soc Oper Res; IAENG Soc Sci Comp; IAENG Soc Software Engn; IAENG Soc Wireless Networks; IAENG Soc HIV/AIDS ISSN: 2078-0958 Type: Proceedings Paper","","","","Open Source Software; City Government; Municipal Government","","Ao, SI; Douglas, C; Grundfest, WS; Burgstone, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The utilization of OSS is essential as costs around the world continue to rise for education, institutions must become innovative in the ways they teach and grow Science, Technology, Engineering, & Mathematics (STEM) majors. To do this effectively professors and administrative staff should push toward the utilization of OSS and other available tools to enhance or supplement currently available tools with minimal integration costs. The OSS applications would allow students the ability to learn critical technological skills for success at small fraction of the cost. OSS also provides faculty members the ability to have students dissect source code, analyze network traffic, create virtual instances of real Operating Systems (OSs), and prepare students for low level software development. It is critical that all institutions look at alternatives in providing training and delivering educational material regardless of limitations going forward as the world continues to be more global due to the increased use of technologies everywhere. Through reviewing the available technology, possible implementations of these technologies, and the application of these items in industry could provide a starting point in integrating these tools into academia.

These have been used as the basis to support the discovery of successful genetic modifications of the microbial metabolism to address industrial goals. However, the use of these methods has been restricted to bioinformaticians or other expert researchers. The main aim of this work is, therefore, to provide a user-friendly computational tool for Metabolic Engineering applications. Results: OptFlux is an open-source and modular software aimed at being the reference computational application in the field. It is the first tool to incorporate strain optimization tasks, i.e., the identification of Metabolic Engineering targets, using Evolutionary Algorithms/Simulated Annealing metaheuristics or the previously proposed OptKnock algorithm. It also allows the use of stoichiometric metabolic models for (i) phenotype simulation of both wild-type and mutant organisms, using the methods of Flux Balance Analysis, Minimization of Metabolic Adjustment or Regulatory on/off Minimization of Metabolic flux changes, (ii) Metabolic Flux Analysis, computing the admissible flux space given a set of measured fluxes, and (iii) pathway analysis through the calculation of Elementary Flux Modes. OptFlux also contemplates several methods for model simplification and other pre-processing operations aimed at reducing the search space for optimization algorithms. The software supports importing/exporting to several flat file formats and it is compatible with the SBML standard. OptFlux has a visualization module that allows the analysis of the model structure that is compatible with the layout information of Cell Designer, allowing the superimposition of simulation results with the model graph. Conclusions: The OptFlux software is freely available, together with documentation and other resources, thus bridging the gap from research in strain optimization algorithms and the final users. It is a valuable platform for researchers in the field that have available a number of useful tools. Its open-source nature invites contributions by all those interested in making their methods available for the community. Given its plug-in based architecture it can be extended with new functionalities. Currently, several plug-ins are being developed, including network topology analysis tools and the integration with Boolean network based regulatory models.","2010-04-19","2025-04-25 15:54:07","2025-04-25 15:54:07","","","","","4","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper proposes a system security assessment method that integrates the risk relationships of open source software (OSS). Firstly, an OSS risk propagation relationship graph is constructed, and the Fuzzy Analytic Hierarchy Process (FAHP)-entropy weight method is adopted to allocate weights to the weakness assessment indicators of OSS, thereby improving the accuracy of quantifying OSS propagation risks. Then, on the attack graph, the analysis of threat values to host nodes and the probability of successful attack paths are optimized from three perspectives: vulnerabilities, OSSSC, and hosts. Experimental results demonstrate that this method, by combining open source risk factors and conducting multi-dimensional analysis, can more effectively assess the security threats faced by systems, providing a more accurate basis for security defense.","2024","2025-04-25 15:54:07","2025-04-25 15:54:07","","21-27","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: N Minzu Univ; Xidian Univ; Future Univ Hakodate; Chuzhou Univ; Ikueikan Univ Type: Proceedings Paper","","","","host status; OSSSC; system security; vulnerability assessment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Closed-loop experiments provide unique insights into brain dynamics and function. To facilitate a wide range of closed-loop experiments, we created an open-source software platform that enables high-performance real-time processing of streaming experimental data. Approach. We wrote Falcon, a C++ multi-threaded software in which the user can load and execute an arbitrary processing graph. Each node of a Falcon graph is mapped to a single thread and nodes communicate with each other through thread-safe buffers. The framework allows for easy implementation of new processing nodes and data types. Falcon was tested both on a 32-core and a 4-core workstation. Streaming data was read from either a commercial acquisition system (Neuralynx) or the open-source Open Ephys hardware, while closed-loop TTL pulses were generated with a USB module for digital output. We characterized the round-trip latency of our Falcon-based closed-loop system, as well as the specific latency contribution of the software architecture, by testing processing graphs with up to 32 parallel pipelines and eight serial stages. We finally deployed Falcon in a task of real-time detection of population bursts recorded live from the hippocampus of a freely moving rat. Main results. On Neuralynx hardware, round-trip latency was well below 1 ms and stable for at least 1 h, while on Open Ephys hardware latencies were below 15 ms. The latency contribution of the software was below 0.5 ms. Round-trip and software latencies were similar on both 32- and 4-core workstations. Falcon was used successfully to detect population bursts online with similar to 40 ms average latency. Significance. Falcon is a novel open-source software for closed-loop neuroscience. It has sub-millisecond intrinsic latency and gives the experimenter direct control of CPU resources. We envisage Falcon to be a useful tool to the neuroscientific community for implementing a wide variety of closed-loop experiments, including those requiring use of complex data structures and real-time execution of computationally intensive algorithms, such as population neural decoding/encoding from large cell assemblies.","2017-08","2025-04-25 15:54:07","2025-04-25 15:54:07","","","","4","14","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP PUBLISHING LTD Type: Article","","","","open-source software; closed-loop neuroscience; multi-threaded software; online burst detection; real-time processing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. Methods: This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Observations: Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Conclusion: Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future.

The PCA denoising method is applied to ten scans of EBSPs from the same region of interest of a recrystallised nickel sample acquired with a decreasing S/N, achieved by reducing the exposure time while increasing the camera gain accordingly. That PCA denoising increases S/N in EBSPs is demonstrated by comparing indexing success rates after both Hough and dictionary indexing (HI and DI) of the Ni patterns having undergone one of four processing routes: i) standard static and dynamic background corrections (standard corrections), ii) standard corrections and pattern averaging with the four closest neighbours, iii) standard corrections and PCA denoising, and iv) standard corrections and pattern averaging followed by PCA denoising. Both pattern averaging and PCA denoising increases the indexing success rates for both indexing approaches for the studied Ni scans, with the former processing route providing the better success rates. The best success rates are obtained after pattern averaging followed by PCA denoising. The potential of PCA denoising to reveal additional pattern details compared to standard corrections and pattern averaging is demonstrated in a pattern from an orthoclase (KAlSi3O8) grain in a geological sample. Software code, and the Ni data sets, are released alongside this article as part of KIKUCHIPY, an open-source software package dedicated to processing and analysis of EBSPs.","2020","2025-04-25 15:54:08","2025-04-25 15:54:08","","","","","891","","","","IOP Conference Series-Materials Science and Engineering","","","","IOP PUBLISHING LTD","DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND","English","","","","","","","Backup Publisher: European Microbeam Anal Soc; Ametek GmbH, Edax Business Unit; Ametek, CAMECA Business Unit; Bruker Nano GmbH; European Commiss, JRC Directorate G Nucl Safety & Secur; Jeol; Micro Nano; Norwegian Univ Sci & Technol; Probe Software; NordicNano Solut AB; Target Messtechnik; TESCAN ORSAY HOLDING a s; Thermo Fisher Sci ISSN: 1757-8981 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While intra-operative ultrasound (iUS) guidance has shown clear potential to reduce surgery time, compared with clinical computed tomography (CT) guidance, rapid registration aiming to correct for patient misalignment has not been addressed. In this article, we present an open-source platform for pedicle screw navigation using iUS imaging. The alignment method is based on rigid registration of CT to iUS vertebral images and has been designed for fast and fully automatic patient re-alignment in the operating room. Two steps are involved: first, we use the iUS probe's trajectory to achieve an initial coarse registration; then, the registration transform is refined by simultaneously optimizing gradient orientation alignment and mean of iUS intensities passing through the CT-defined posterior surface of the vertebra. We evaluated our approach on a lumbosacral section of a porcine cadaver with seven vertebral levels. We achieved a median target registration error of 1.47 mm (100% success rate, defined by a target registration error <2 mm) when applying the probe's trajectory initial alignment. The approach exhibited high robustness to partial visibility of the vertebra with success rates of 89.86% and 88.57% when missing either the left or right part of the vertebra and robustness to initial misalignments with a success rate of 83.14% for random starts within +/- 20 degrees rotation and +/- 20 mm translation. Our graphics processing unit implementation achieves an efficient registration time under 8 s, which makes the approach suitable for clinical application.

Preparing two SAGES tools, OpenESSENCE and SAGES Mobile, for release as open-source software projects entailed a multifaceted, months-long effort that spanned policy, technical, and community considerations.

In such platforms, developers have to collaborate and deal with issues of collaboration in open-source software development. Although collaboration is challenging, collaborative development produces better software systems than any developer could produce alone. Several approaches have investigated collaboration challenges, for instance, by proposing or evaluating models and tools to support collaborative work. Despite the undeniable importance of the existing efforts in this direction, there are few works on collaboration from perspectives of developers. In this work, we aim to investigate the perceptions of open-source software developers on collaborations, such as motivations, techniques, and tools to support global, productive, and collaborative development. Following an ad hoc literature review, an exploratory interview study with 12 open-source software developers from GitHub, our novel approach for this problem also relies on an extensive survey with 121 developers to confirm or refute the interview results. We found different collaborative contributions, such as managing change requests. Besides, we observed that most collaborators prefer to collaborate with the core team instead of their peers. We also found that most collaboration happens in software development (60%) and maintenance (47%) tasks. Furthermore, despite personal preferences to work independently, developers still consider collaborating with others in specific task categories, for instance, software development. Finally, developers also expressed the importance of the social coding platforms, such as GitHub, to support maintainers, and contributors in making decisions and developing tasks of the projects. Therefore, these findings may help project leaders optimize the collaborations among developers and reduce entry barriers. Moreover, these findings may support the project collaborators in understanding the collaboration process and engaging others in the project.","2023-05","2025-04-25 15:54:08","2025-04-25 15:54:08","","","","5, SI","35","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","distributed collaboration; collaborative software development; collaboration in software development; open-source software projects; sustained developer community participation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 15:54:08","2025-04-25 15:54:08","","116-150","","1","32","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","social networks; software development; open source software development; team formation; project success; exploitation and exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the “virtuous circle” supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other.

Although existing research recognizes the importance of trust, there is a lack of an effective and scalable computational method to measure trust in an OSS community. Consequently, OSS project members must rely on subjective inferences based on fragile and incomplete information for trust-related decision making. We propose an automated approach to assist a developer in identifying the trustworthiness of another developer. Our two-fold approach, first, computes direct trust between developer pairs who have interacted previously by analyzing their interactions via natural language processing. Second, we infer indirect trust between developers who have not interacted previously by constructing a community-wide developer network and propagating trust in the network. A large-scale evaluation of our approach on a GitHub dataset consisting of 24,315 developers shows that contributions from trusted developers are more likely to be accepted to a project compared to contributions from developers who are distrusted or lacking trust from project members. Further, we develop a pull request classifier that exploits trust metrics to effectively predict the likelihood of a pull request being accepted to a project, demonstrating the practical utility of our approach.","2019-12-30","2025-04-25 15:54:08","2025-04-25 15:54:08","","","","12","14","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We extract a series of measures based on those used in traditional inspection experiments. We measure the frequency of review, the size of the contribution under review, the level of participation during review, the experience and expertise of the individuals involved in the review, the review interval, and the number of issues discussed during review. We create statistical models of the review efficiency, review interval, and effectiveness, the issues discussed during review, to determine which measures have the largest impact on review efficacy. We find that OSS peer reviews are conducted asynchronously by empowered experts who focus on changes that are in their area of expertise. Reviewers provide timely, regular feedback on small changes. The descriptive statistics clearly show that OSS review is drastically different from traditional inspection.","2014-08","2025-04-25 15:54:09","2025-04-25 15:54:09","","","","4, SI","23","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","Measurement; Management; mining software repositories; Peer review; open-source software; inspection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweight open source systems for patient and sample information management. Results: We present a web-based tool for submission, management and retrieval of sample and research subject data. The system secures confidentiality by separating anonymized sample information from individuals' records. It is simple and generic, and can be customised for various biomedical studies. Information can be both entered and accessed using the same web interface. User groups and their privileges can be defined. The system is open-source and is supplied with an on-line tutorial and necessary documentation. It has proven to be successful in a large international collaborative project. Conclusion: The presented system closes the gap between the need and the availability of lightweight software solutions for managing information in biomedical studies involving human research subjects.","2007-02-09","2025-04-25 15:54:09","2025-04-25 15:54:09","","","","","8","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, since reused components are (by definition) generic, they need to be customized and integrated into a specific system before they can be useful. Since this integration is system-specific, the integration effort is non-negligible and increases maintenance costs, especially if more than one component needs to be integrated. This paper performs an empirical study of multi-component integration in the context of three successful open source distributions (Debian, Ubuntu and FreeBSD). Such distributions integrate thousands of open source components with an operating system kernel to deliver a coherent software product to millions of users worldwide. We empirically identified seven major integration activities performed by the maintainers of these distributions, documented how these activities are being performed by the maintainers, then evaluated and refined the identified activities with input from six maintainers of the three studied distributions. The documented activities provide a common vocabulary for component integration in open source distributions and outline a roadmap for future research on software integration.","2016-06","2025-04-25 15:54:09","2025-04-25 15:54:09","","960-1001","","3","21","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Debian; Software reuse; Open source distributions; Software integration; Ubuntu and FreeBSD","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores a prediction method based on fuzzy time series for predicting the future commit activity in open source software (OSS) projects. The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems. It is found that the predicted results of the computational method outperform various ARIMA models. Towards the end, a commit prediction model is used for each project to analyse the trends in their commit activity.","2016-10","2025-04-25 15:54:09","2025-04-25 15:54:09","","136-146","","5","10","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","public domain software; open source software projects; OSS projects; time series; ARIMA model; autoregressive integrated moving average models; autoregressive moving average processes; commit activity prediction; development community; fuzzy analysis; fuzzy set theory; fuzzy time series-based prediction method; software development management; software evolution prediction; time variant difference parameter","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.","2015-03","2025-04-25 15:54:09","2025-04-25 15:54:09","","224-237","","1","26","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software; intrinsic motivation; firm attributes; firm sponsorship; voluntary contributions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software is a recent and important example. Copyright restrictions on open-source projects stipulate that any user may modify the software so long as any resulting innovation is freely available to all. In economic parlance, the innovation is a public good. The economic theory of public-good provision raises a number of important questions. Who contributes to such a project, and who free rides? How might a social planner exploit the interdependence of project components to encourage contributions? Under what conditions will such actions result in successful provision? Using a simple game-theoretic framework and recent results from the study of equilibrium selection, we attempt to answer these questions. Under reasonable assumptions of asymmetry and less than complete information, the most efficient providers will contribute. Contributions can be elicited by `integrating' the provision process when providers are sufficiently optimistic about the success of the project. Otherwise, the social planner may be better off `separating' the components so that individual contributions are independent of each other. The analysis yields recommendations for the leaders of open-source projects and other similar collective-action problems.","2002","2025-04-25 15:54:09","2025-04-25 15:54:09","","446-461","","4","18","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there were few developers being paid directly for maintaining OSS projects in the past. The GitHub Sponsors program that brings financial supports to the general OSS developers in GitHub-the world's largest OSS platform may make a difference on this situation in the future. In this paper, we present a data set on GitHub Sponsors and conduct a data-driven study to analyze the participants of the program and the impact of sponsorships to developers' activities and their projects' outcomes and qualities. The results of our survey suggest that most developers state they will contribute more with sponsorships and provide some privilege for their sponsors. And through quantitative study, we find that developers make more contributions on GitHub after they got/offered sponsorships. Moreover, gaining sponsorship also has a weakly positive impact on developers' collaborators that did not get sponsorship. And not only developers, but their own or contributed projects also can be motivate by sponsorships. Our findings are useful to the community by understanding the impact of sponsorships on users' activities and projects' progress and sustainability, and helping the managers to improve the current financial support mechanism.","2022","2025-04-25 15:54:09","2025-04-25 15:54:09","","924-933","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc Type: Proceedings Paper","","","","Open Source Software; Data-Driven Study; Financial Support; GitHub Sponsors","","Leong, HV; Sarvestani, SS; Teranishi, Y; Cuzzocrea, A; Kashiwazaki, H; Towey, D; Yang, JJ; Shahriar, H","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

Unfortunately, there is Pareto principle in OSSD projects, and a large number of OSSD projects have little influence, many projects a re unable to attract user interest. Therefore, it is important to understand the factors affecting OSSD project success as measured by project popularity. While technical factors such as license and compatibility with certain operating systems have a direct influence on the popularity of OSSD projects, development-related factors also have latent impacts on the popularity of OSSD projects. Therefore, we collect data on 445 projects and successfully build a structural equation model (SEM) which depicts the inherent relationships between development-related factors and OSSD project popularity.

Cross-language software similarity detection is inherently more challenging due to variations in language, application structures, support libraries used, and naming conventions. In this paper we propose a novel model, CroLSim, to detect similar software applications across different programming languages. We define a semantic relationship among cross-language libraries and API methods (both local and third party) using functional descriptions and a word-vector learning model. Our experiments show that CroLSim can successfully detect cross-language similar software applications, which outperforms all existing approaches (mean average precision rate of 0.65, confidence rate of 3.6, and 75% highly rated successful queries). Furthermore, we applied CroLSim to a source code repository to see whether our model can recommend cross-language source code fragments if queried directly with source code. From our experiments we found that CroLSim can recommend cross-language functional similar source code when source code is directly used as a query (average precision=0.28, recall=0.85, and F-Measure=0.40).

Our aim is to explore the intersection between FOSS and computational reproducibility. We begin by situating FOSS in relation to other `open' initiatives, and specifically open science, open research, and open scholarship. In this context, we argue that anyone who actively contributes to the research process today is a computational researcher, in that they use computers to manage and store information. We then provide a primer to FOSS suitable for anyone concerned with research quality and sustainability-including researchers in any field, as well as support staff, administrators, publishers, funders, and so on. Next, we illustrate how the notions introduced in the primer apply to resources for scientific computing, with reference to the GNU Scientific Library as a case study. We conclude by discussing why the common interpretation of `open source' as `open code' is misplaced, and we use this example to articulate the role of FOSS in research and scholarship today.

OSS represents an effective development model because it harnesses the decentralized efforts of many developers in a way that scales. As OSS developers work independently on interdependent modules, they create a larger cohesive whole in the form of an ecosystem, leaving traces of their contributions and collaborations. Data harvested from these traces enable the study of large-scale decentralized collaborative work. We present curated data on the activity of tens of thousands of developers in the Rust ecosystem and the evolving dependencies between their libraries. The data covers eight years of developer contributions to Rust libraries and can be used to reconstruct the ecosystem's development history, such as growing developer collaboration networks or dependency networks. These are complemented by data on downloads and popularity, tracking dynamics of use, visibility, and success over time. Altogether the data give a comprehensive view of several dimensions of the ecosystem.","2022-11-16","2025-04-25 15:54:10","2025-04-25 15:54:10","","","","1","9","","","","","","","","","","English","","","","","","","Place: HEIDELBERGER PLATZ 3, BERLIN, 14197, GERMANY Publisher: NATURE PORTFOLIO Type: Article; Data Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Aligned with work that builds on the notion that an OSS development is tightly interrelated with its social environment (i.e., the OSS community), this study examines the relationship between interproject structure and OSS project success. OSS project success is reflected in two forms: popularity and knowledge creation. Extending the extant OSS literature, we theorize a contingent role of interproject connectedness. In particular, we posit three points: (1) an OSS project with more structural holes achieves higher popularity; (2) an OSS project with fewer structural holes yields higher knowledge creation; and (3) these two relationships are enhanced by an increase in project maturity. Using a dataset longitudinally collected from SourceForge.net, we found that OSS projects with widespread connectedness are more popular. This is especially so for those OSS projects in the mid-mature stage. We also found that OSS projects with a cohesive network achieve higher knowledge creation, irrespective of their maturity. Findings from our study can contribute to OSS literature by identifying OSS projects that are more likely to be successful.","2021-03","2025-04-25 15:54:10","2025-04-25 15:54:10","","","","1","30","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source software; Popularity; Maturity; Interproject connectedness; Knowledge creation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This surge in unmanned aerial vehicles has increased attention towards monitoring tasks in vital areas, such as urban spaces for security, surveillance or Internet of the Things applications. In this sense, we propose an open-source software-in-the-loop approach that integrates the complete navigation experience, accounting for potential wind-related effects, and providing realistic 3D modeling of scenarios encompassing open spaces in city landscapes. Our work introduces a wind perturbation estimation strategy, which models the wind effect as an external force along the Zaxis based on altitude variations from real flights. Validation was conducted using real data flights with a quadrotor aiding the navigation with Ardupilot and QgroundControl as a ground station. To complement the experiments we include a small test with a fixed-wing plane to asses the software-in-the-loop accuracy on larger trajectories. Results demonstrate successful tracking of altitude variations, yielding errors below 10% relative to the home position in experiments with average trajectory lengths of 150 m in two scenarios in Quito. The software-in-the-loop simulation aimed to replicate wind conditions specific to the date and time of real data acquisition, providing a platform to emulate possible improvements and assess UAV performance before deployment in actual missions. This research not only contributes to the optimization of monitoring capabilities but also serves as a valuable tool for assessing UAV missions in diverse and dynamic environments.","2024","2025-04-25 15:54:10","2025-04-25 15:54:10","","1453-1460","","","","","","","International Conference on Unmanned Aircraft Systems","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE ISSN: 2373-6720 Type: Proceedings Paper","","","","Ardupilot; Gazebo; ROS; Software-in-the-loop; wind perturbation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of orthopaedic and dental implants it was found that geometry and surface topography are crucial for short and long-term success of the implant, due to its effects in osseointegration. Properties of implant surfaces have been studied in the last decade in a concentrated effort to improve osseointegration process and implant success. Several researchers have proved that roughness of implant surface is related to healing time and integration between the implants and the bone, but the parameters on the surface creation are not fully controllable with current processes. In this work, computational algorithms are proposed for implant surface design in order to control the parameters required for this application. As a result it is presented an open-source software tool, called POMES - Porous and Modifications for Engineering Surfaces - , to design porous/roughness on top of surfaces in any geometry.

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-forprofit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 15:54:10","2025-04-25 15:54:10","","32-39","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, download counts and averages do not convey as much information as the patterns in the original downloads time series. In this research, we propose a method to increase the expressiveness of mere download rates by considering download patterns against software releases. We apply experimentally our method to the most downloaded projects of Source Forge's history crawled through the FLOSSMole repository. Findings show that projects with similar usage can have indeed different levels of sensitivity to releases, revealing different behaviors of users.

There are continuing debates over the future of software and, in particular, the competition between OSS and proprietary software. Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. The government environment is changing rapidly in areas as diverse as homeland security and social services. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied-especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 15:54:10","2025-04-25 15:54:10","","227-238","","2","44","","","","","","","","","","English","","","","","","","Place: 1 NEW ORCHARD ROAD, ARMONK, NY 10504 USA Publisher: IBM CORP Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The findings were analysed through the lens of administrative complexity associated with OSS adoption. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS.

Root characteristics like length, diameter and volume are critical to measure to understand plant and soil functions. RhizoVision Explorer is an open-source software designed to enable researchers interested in roots by providing an easy-to-use interface, fast image processing and reliable measurements. The default broken roots mode is intended for roots sampled from pots and soil cores, washed and typically scanned on a flatbed scanner, and provides measurements like length, diameter and volume. The optional whole root mode for complete root systems or root crowns provides additional measurements such as angles, root depth and convex hull. Both modes support providing measurements grouped by defined diameter ranges, the inclusion of multiple regions of interest and batch analysis. RhizoVision Explorer was successfully validated against ground truth data using a new copper wire image set. In comparison, the current reference software, the commercial WinRhizo (TM), drastically underestimated volume when wires of different diameters were in the same image. Additionally, measurements were compared with WinRhizo (TM) and IJ_Rhizo using a simulated root image set, showing general agreement in software measurements, except for root volume. Finally, scanned root image sets acquired in different labs for the crop, herbaceous and tree species were used to compare results from RhizoVision Explorer with WinRhizo (TM). The two software showed general agreement, except that WinRhizo (TM) substantially underestimated root volume relative to RhizoVision Explorer. In the current context of rapidly growing interest in root science, RhizoVision Explorer intends to become a reference software, improve the overall accuracy and replicability of root trait measurements and provide a foundation for collaborative improvement and reliable access to all.","2021-09-13","2025-04-25 15:54:10","2025-04-25 15:54:10","","","","6","13","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","Ground truth; phenomics; phenotyping; rhizosphere; root system architecture; traits","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Design/methodology/approach - Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. Findings - There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and “tribal knowledge” that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. Originality/value - The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 15:54:11","2025-04-25 15:54:11","","211-223","","2","28","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LIMITED Type: Article","","","","Software tools; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our experience in the design and implementation of the model provides useful insights into emerging ICT trends and the means for ISP providers to identify, at an early stage, the requirements for creating successful products and services ecosystem.","2013","2025-04-25 15:54:11","2025-04-25 15:54:11","","13-20","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Commun Soc; NICT; NTT; OKI; KDDI; NEC; Hitachi; Fujitsu; Mitsubishi Elect; Huawei Japan; Telkom SA; RIM; Int Telecommunicat Union; Inst Elect, Informat & Commun Engineers Japan Type: Proceedings Paper","","","","Cloud computing; ICT; Information assets; Information Services platform; Open Source Communities; Prosumers; Web Services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As knowledge-based firms, COSS companies' success depends heavily on the interplay among intangible resources such as human capital, relational capital, structural capital, and software quality. To observe these relationships, we conducted a hypothesis-testing questionnaire-type survey involving 200 software development experts and professionals working at 60 multinational COSS companies. Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model. Therefore, COSS companies may need to prioritize software quality as it is the most critical variable impacting the success of COSS companies.","2022","2025-04-25 15:54:11","2025-04-25 15:54:11","","46490-46503","","","10","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","Open source software; Software; software quality; Companies; Knowledge management; Software quality; Commercial open-source software; company success; Integrated circuits; intellectual capital; Knowledge based systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The stability and longevity of this group of most active developers are crucial for the success of the project. While there has been prior work on identifying key individuals in open source development, little attention has been devoted to the identification of cross-cutting core individuals (boundary spanners) whose responsibilities span across different functional areas of open source development (e.g., who are involved both in development-centric activities and user-centric activities). To address this gap, we propose an approach to identify the core cross-cutting members and their roles within the community through analyzing email communication repositories. We use Social Network Analysis (SNA) tools to identify the most active core members in different forums (that have different focus such as Python-dev that focuses on language evolution and Python Lists that focus on user support), and their activities over time, thus identifying the core developers and their involvement in different community mailing lists. Based on the involvement of a core developer and the overall social structure of the network of core developers, we also present an approach for identifying a potential replacement for a community administrator that steps down. Using email repositories of six main Python forums as the case study domain, we computed several social network analysis metrics to characterize the core developers and their importance in the Python community.","2017","2025-04-25 15:54:11","2025-04-25 15:54:11","","308-317","","","","","","","Asia-Pacific Software Engineering Conference","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","ISSN: 1530-1362 Type: Proceedings Paper","","","","Social Network Analysis; Python; Open Source Software Development; Community Development","","Lv, J; Zhang, H; Hinchey, M; Liu, X","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Including function points and its variants, there are several size measures and corresponding measurement methods that can be used for effort estimation. However, in most of the projects, there is limited amount of information available in the early stages and significant effort is spent for size measurement and effort estimation with such methods. This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software. For this purpose, we consider open source project management and game software. We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., conceptual) and solution domain (i.e., design) models. The results reveal a high correlation between the number of conceptual classes in the problem domain model and the number of software classes constituting the corresponding software. The results suggest that it is possible to use problem domain descriptions in the early stages of software development projects to make plausible predictions for the size of the software.","2014","2025-04-25 15:54:11","2025-04-25 15:54:11","","81-84","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","conceptual models; linear regression model for size estimation; size estimation","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments.

This paper describes a software development process that has proven vital to the success of the widely used open-source toolkits ITK (itk.org) and VTK (vtk.org). This process facilitates cross-platform development, includes automatic documentation generation, integrates continuous testing, and posts the results of the process on publicly accessible web pages. The net result is that a responsive feedback loop is created between the developers in the community and automated processes to measure software quality. With this process software converges towards better software as long as the process is enforced.

However, ERP systems are complex tools, particularly for small and medium size enterprises (SMEs). For this reason, new ERP configurations have arisen, such as Open Source Software-ERP (OSS-ERP). In the website Sourceforge.net, we can identify 2058 projects about OSS-ERP, although all of them have not had an impact on the ERP market. This data is indicative of the increasing relevance of this enterprise solution for organizations. At this moment, the OSS-ERP vendors with a greater diffusion are Compiere, Openbravo, Abanq (previously FacturaLux), ERP5, Tiny ERP, Fisterra, OFBiz, SQL-Ledger and WebERP. OSS-ERP has three relevant advantages for organizations: (1) increased adaptability, (2) decreased reliance on a single supplier, (3) reduced costs. OSS-ERP generally include the necessary functions to integrally manage all the activities of a company. Due to their high flexibility, these tools can be adapted to the client's specific needs. Furthermore, as OSS-ERP are based on open software technologies, organizations do not have to pay licenses or exclusive contracts. With the collaboration of partners, OSS-ERP vendors receive benefits for the support services. Research in OSS has identified individual personal motives for using OSS software, analyzing specific OSS solutions, or the OSS movement itself. The literature in Enterprise solutions has also analyzed the main organizational factors for successfully implementing an ERP system. However, OSS-ERP is a research topic barely analyzed by the literature. This paper's aim is to specifically focus on the organizational and motivational factors for implementing OSS-ERP. The authors developed a research work for testing the impact of organizational and motivational factors on the implementation of OSS-ERP by means of a survey of organizations with OSS-ERP and OSS-ERP users.","2010","2025-04-25 15:54:12","2025-04-25 15:54:12","","257-273","","","","","","","Computer Science Technology and Applications","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Taylor, JR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Findings From the survey, the authors identify significant barriers and drivers that US academic libraries may consider before adopting OSS and found that awareness itself is not a barrier. While about half of respondents confirmed using OSS, the authors found surprisingly low levels of intent to adopt from current non-adopters. Practical implications - This research offers insights for promoting OSS adoption. Also, it provides funding agencies and administrators with guidelines to encourage successful deployment of OSS in higher education.

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers' positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-07","2025-04-25 15:54:12","2025-04-25 15:54:12","","","","4","32","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","hierarchy; developer networks; Open-source software projects; organizational structure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to meet user needs and functional changes, open-source software continuously improves its software quality through successive releases. Due to the iterative development process of open-source software, open-source software testing also requires continuous learning to understand the changes in the software. Therefore, the fault detection process of open-source software involves a learning process. Additionally, the complexity and uncertainty of the open-source software development process also lead to stochastically introduced faults when troubleshooting in the open-source software debugging process. Considering the phenomenon of learning factors and the random introduction of faults during the testing process of open-source software, this paper proposes a reliability modeling method for open-source software that considers learning factors and the random introduction of faults. Least square estimation and maximal likelihood estimation are used to determine the model parameters. Four fault data sets from Apache open-source software projects are used to compare the model performances. Experimental results indicate that the proposed model is superior to other models. The proposed model can accurately predict the number of remaining faults in the open-source software and be used for actual open-source software reliability evaluation.","2024-01","2025-04-25 15:54:12","2025-04-25 15:54:12","","","","2","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source software; learning factors; software reliability model; stochastic differential equation; stochastically introduced faults","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review; (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects; (iii) 24 responses to a questionnaire sent to 9 OSS projects; and (iv) semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practitioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteristics, reception issues, orientation, technical hurdles, and documentation problems. We could observe recurrent barriers evidenced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-25 15:54:12","2025-04-25 15:54:12","","51+","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Univ Fed Alagoas; Ufal; CAPES; Conselho Nacl Desenvolvimento Cientifico & Tecnologico; Ines; Google; Inst Fed Alagoas; Aloo Telecom; Alagoas Governo Estado, Secretaria Estado Turismo; Maceio Convent & Visitors Bur; Soc Brasileira Computacao; Josi Mendes Consultoria & Eventos; Transamerica Turismo; IEEE Comp Soc Type: Proceedings Paper","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 15:54:12","2025-04-25 15:54:12","","156-187","","2","25","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Open source software; Open source; Diffusion; Case studies; Adoption; Diffusion theory; Public sector organizations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context. We conclude by discussing governance issues related to the disciplined use and reuse of open source and areas for further improvements.","2022","2025-04-25 15:54:12","2025-04-25 15:54:12","","154-163","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Siemens; Pure Syst; Assoc Comp Machin; Graz Univ Tech; Itk Engn; Combeenation; Select Arts; Stream Diver; Hitec; Stadt Graz.at; Elsevier Journal Syst & Software Type: Proceedings Paper","","","","open source software; dependencies; NPM; DevSecOps; Maven","","Felfernig, A; Fuentes, L; Cleland-Huang, J; Assuncao, WKG; Falkner, A; Azanza, M; Luaces, MAR; Bhushan, M; Semini, L; Devroey, X; Werner, CML; Seidl, C; Le, VM; Horcas, JM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A total of 220 patients (1020 observations) who received vancomycin TDM services were included in the dataset. A population PK analysis was performed using non-linear mixed effects modeling, and a covariate evaluation was conducted. A two-compartment model with first-order elimination best explained the vancomycin PK, with estimates of 2.82 L/h, 31.8 L, 11.7 L/h, and 75.4 L for CL, V-1, Q, and V-2, respectively. In the covariate analysis, weight correlated with the volume of the peripheral compartment, and creatinine clearance, hemodialysis, and continuous renal replacement therapy treatments contributed to the clearance of vancomycin. The results show the clear need to optimize the PK parameters used for TDM in Korean patients. Specifically, V-1 should be smaller for Korean patients, and renal replacement therapies should be considered in TDM practice. This final model was successfully applied in R shiny as open-source software for Koreans.","2019-05","2025-04-25 15:54:12","2025-04-25 15:54:12","","","","5","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source software; Korean; population pharmacokinetics; therapeutic drug management; vancomycin","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine the two peer review techniques used by the successful, mature Apache server project: review-then-commit and commit-then-review. Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects. We provide a comparison of the two Apache review techniques as well as a comparison of Apache review to inspection in an industrial project. We conclude that Apache reviews can be described as (1) early, frequent reviews (2) of small, independent, complete contributions (3) conducted asynchronously by a potentially large, but actually small, group of self-selected experts (4) leading to an efficient and effective peer review technique.","2008","2025-04-25 15:54:12","2025-04-25 15:54:12","","541-550","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: ACM SIGSOFT; IEEE CSE; Univ Paderborn; Univ Leipzig; SIEMENS; Zuhlke; Adesso; Deutsch Telekom Labs; sd&m; Werum; Microsoft Res; IBM; i nemis; dSPACE Type: Proceedings Paper","","","","Open source software; Peer review; Inspection; Mining software repositories (email)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use Of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are also likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization, that naturally fix themselves during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-25 15:54:12","2025-04-25 15:54:12","","97-106","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc, Tech Comm Fault Tolerant Comp; IFIP Working Grp 10 4 Dependable Comp & Fault Tolerance; AT&T; Lucent Technologies; Compaq Comp Corp; Georgia Inst Technol; IBM Corp; LAAS CNRS; Microsoft Corp Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conduct an explorative case study at Siemens AG. Siemens introduced a formal template process which can be adapted by the organizational units according to their demands. Results show that the extent to which the process is implemented depends on the level of closeness to core intellectual property of the organizational unit and the intensity of the involvement in OSS communities.

It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects.","2024-05","2025-04-25 15:54:12","2025-04-25 15:54:12","","","","5","36","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","software evolution; assessment model; open source software engineering; software resilience","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Following a survey of 222 FOSS developers, we find conflict to have an overall negative effect on developer retention. Furthermore, different types of conflict have varying impact on outcomes. In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes. Though we find structural factors like task interdependence and geographical distribution increase overall conflict levels in FOSS teams, participatory decision-making and a transformational leadership style have an ameliorating effect.

The study investigates factors that affect the selection of software for public sector information systems with, an emphasis on how Free and Open Source Software ( FOSS) is used and could be used in such projects. The objectives of the study are as follows. The study aims to identify factors that affect the adoption of Software in Sri Lankan government sector projects. In addition to this it identifies features that are considered as important in such large Information Systems, and how they relate to Open Source Software adoption in the context of the public sector in Sri Lanka. The findings are analyzed and suitable recommendations are presented for better selection of software in the public sector. The work is important as it identifies and highlights factors that affect the choice of software in the public sector. This is important for several categories of people. It is of importance to the strategic management and policy makers to know what drives the information system procurement decisions in order to make more relevant policies and guidelines that are congruent with the needs in government sector departments. It is useful when advocating new technologies and information systems. This is especially true when advocating the use of Free and Open Source software for the use in the public sector in a wholesome and sustainable manner. The research is also important to software vendors and solution providers to the public sector in identifying what factors need to be taken in to account when bidding for public sector IS projects. The research is of a qualitative nature. It consists of multiple case studies of selected government sector departments and projects in Sri Lanka. The study investigates information systems developed by internal staff, developed by external consultants, procured systems, system implementation via private public partnerships (PPP) and projects guided by the Information and Communication Technology Agency (ICTA) of Sri Lanka. Data was gathered through interviews of staff at different levels of selected government sector Information Systems projects. The data was comparatively analyzed on a case by case basis to identify common patterns and trends among the investigated organizations and projects. The identified factors affecting the choice of software include the cost, technical specifications, bidder's expertise in selected technology and user's expertise in selected technology amongst other factors described in the full paper. The study identifies patterns between the choice of software - FOSS or non FOSS, and these identified factors.

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 15:54:13","2025-04-25 15:54:13","","1439-1458","","3","44","","","","","","","","","","English","","","","","","","Place: UNIV MINNESOTA-SCH MANAGEMENT 271 19TH AVE SOUTH, MINNEAPOLIS, MN 55455 USA Publisher: SOC INFORM MANAGE-MIS RES CENT Type: Article","","","","Open source software; product quality; signaling; takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Previous work done by Hinds [5] suggested social network structure was instrumental towards the success of an OSS project, as measured by activity and output. The follow-up paper by Thuds [4] discovered that his hypotheses, based on social network theory and previous research on the importance of subgroup connectedness, were vastly different than the results of his study of over 100 successful OSS projects. He concluded that the social network structure had no significant effect on project success We outline how his approach disregarded potentially important factors and through a new study evaluate the role of the OSS developer network as it pertains to long-term project popularity. We also present an initial investigation into the adequacy of using the SourceForge activity percentile as a long-term success metric In contrast with Hinds, we show that previously existing developer-developer ties are an indicator of past and future project popularity.","2010","2025-04-25 15:54:13","2025-04-25 15:54:13","","2887-2896","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Univ Hawaii, Shidler Coll Business ISSN: 1060-3425 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research indicates that the success mode for open source software projects in China relies a lot on the project initiators. Project initiators not only contribute codes to aid the project directly, but also use their social capital to facilitate the project success. But no full play has been given to social network's effect on mass production and collaborative innovation. The authors suggest collaborative innovation which could lead to coherence of global collective wisdom, reduced development costs, and expanded source of innovation should be the further direction for the OSS project in emerging platforms.","2020-03","2025-04-25 15:54:13","2025-04-25 15:54:13","","28-43","","1","12","","","","","","","","","","English","","","","","","","Place: 701 E CHOCOLATE AVE, STE 200, HERSHEY, PA 17033-1240 USA Publisher: IGI GLOBAL Type: Article","","","","Project Success; Open Source Software Project; Project Initiator; Social Capital","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the differential impacts of such social influence on developers' initial and sustained participation behaviors were largely overlooked in previous research. We empirically studied the impacts of two social influence mechanisms-word-of-mouth (WOM) and observational learning (OL)-on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.","2021-09","2025-04-25 15:54:13","2025-04-25 15:54:13","","1133-1147","","9","72","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, integrating external and internal sources of social capital is challenging and identifying appropriate integration strategies is crucial for the success of such endeavors. This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success. We also show that when development environment difference is moderate, the impact of role diversity is the most positive.

Abstractions of MPL systems are derived as finite-state transition systems. A transition system is obtained first by partitioning the state space of the MPL system into finitely many regions and then by associating a unique state of the transition system to each partitioning region. Relations among the states of the transition system are then set up based on the underlying dynamical transitions between the corresponding partitioning regions of the MPL state space. In order to establish formal equivalences, the obtained finite abstractions are proven either to simulate or to bisimulate the original MPL system. The approach enables the study of general properties of the original MPL system formalized as logical specifications, by verifying them over the finite abstraction via model checking. The article presents a new, extended and improved implementation of a software tool (available online) for the discussed formal abstraction of MPL systems, and is tested on a numerical benchmark against a previous version.","2016-03","2025-04-25 15:54:13","2025-04-25 15:54:13","","109-145","","1, SI","26","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Bisimulations; Difference-bound matrices; Discrete-event systems; Max-plus algebra; Model abstractions; Model checking; Piece-wise affine systems; Transition systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from ultra-high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically.

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 7 0 0; 0 0 0 bug reports obtained from the BUGZILLA installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3% with an associated recall of 38.9%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.","2013","2025-04-25 15:54:14","2025-04-25 15:54:14","","1032-1041","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM Special Interest Grp Software Engn; IEEE Comp Soc; Tech Council Software Engn Type: Proceedings Paper","","","","","","Notkin, D; Cheng, BHC; Pohl, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is time-consuming because of the bioinformatics processes involved, including sequence trimming, consensus sequence generation, and public database searches. We developed a simple and fully automated software that enabled species-level identification of NTM from trace files, SnackNTM (https://github.com/Young-gonKim/SnackNTM). Methods: JAVA programing language was used for software development. The SnackNTM diagnostic algorithm utilized 16S rRNA gene sequences, according to the Clinical & Laboratory Standards Institute guidelines, and an rpoB gene region was adjunctively utilized to narrow down the species. The software performance was validated using trace files of 234 clinical cases, comprising 217 consecutive cases and 17 additionally selected cases of unique species. Results: SnackNTM could analyze multiple cases at once, and all the bioinformatics processes required for sequence-based NTM identification were automatically performed with a single mouse click. SnackNTM successfully identified 95.9% (208/217) of consecutive clinical cases, and the results showed 99.0% (206/208) agreement with manual classification results. SnackNTM successfully identified all 17 cases of unique species. In a processing time comparison test, the analysis and reporting of 30 cases, which took 150 minutes manually, took only 40 minutes with SnackNTM. Conclusions: SnackNTM is expected to reduce the workload for NTM identification, especially in clinical laboratories that process large numbers of cases.","2022-03","2025-04-25 15:54:14","2025-04-25 15:54:14","","213-248","","2","42","","","","","","","","","","English","","","","","","","Place: A505-ASTERIUM SEOUL, 372 HANGANG-DAERO, YONGSAN-GU, SEOUL, 04323, SOUTH KOREA Publisher: KOREAN SOC LABORATORY MEDICINE Type: Article","","","","16S rRNA gene; Nontuberculous mycobacteria; NTM identification; rpoB; SnackNTM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. Conclusion: We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care. (C) 2009 Elsevier Ireland Ltd.

For over a decade, the digital communities around the globe have used FOSS packages not only as an inexpensive way to access to information available on Internet, but also to disseminate thoughts, opinions and concerns about various socio-political and economic matters. Proxy servers and FOSS played a vital role in helping citizens in repressed countries to bypass the state imposed Internet content filtering and censorship practices. On the one hand, proxy servers act as redirectors to websites, and on the other hand, many of these servers are the main source for downloading FOSS anti-filtering software packages. These packages can provide secure web surfing via anonymous web access, data encryption. IP address masking, location concealment, browser history and cookie clean-ups but they also provide proxy software updates as well as domain name updates. The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In particular, they are poorly adapted to the slow Internet connections in many developing countries such as Iran. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net.

Objective: This work is aimed at studying the communication functions of bug comments and their associations with fast and complete bug fixing in OSS development. Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist. The results of this work could be used to improve corrective tasks in OSS development and some other specific linguistic aspects should be studied in detail in OSS communities.","2021-08","2025-04-25 15:54:14","2025-04-25 15:54:14","","","","","136","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Machine learning; Bug fixing; Communication function; Corrective maintenance; Issue Tracking System; Open Source Software development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity. (C) 2019 The Authors.

This phenomenon is also known as “Inner Source”. While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. Objective: The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Method: Following an initial systematic literature review to generate seed category data constructs, we performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques. Results: We have identified a number of challenges and approaches to address them, and compared the findings to challenges related to development with OSS products reported in the literature. We found that many challenges identified in the case study could be mapped to challenges related to integration of OSS. Conclusion: The results provide important insights into common challenges of developing with OSS and Inner Source and may help organizations to understand how to improve their software development practices by adopting certain OSSD practices. The findings also identify the areas that need further research. (C) 2011 Elsevier B.V.

We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications. By our plug-in, information about measured physiological processes can be obtained and transferred into clinical practice.","2013-04","2025-04-25 15:54:14","2025-04-25 15:54:14","","344-352","","2","26","","","","","","","","","","English","","","","","","","Place: 233 SPRING ST, NEW YORK, NY 10013 USA Publisher: SPRINGER Type: Article","","","","Algorithms; Image processing; Computer-assisted; Magnetic resonance imaging; Perfusion","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields.

In many Open Source Softoware Development (OSSD) communities, DM processes lie buried amongst vast amounts of publicly available data. Hidden within this data lie the rationale for decisions that led to the evolution and maintenance of software products. While there have been some efforts to extract DM processes from publicly available data, the rationale behind `boo' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million mails. This paper makes two main contributions. First. it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second. it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven. bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement). Our approach can be applied to extract rationale in other OSSD communities that have similar governance structures.","2021","2025-04-25 15:54:14","2025-04-25 15:54:14","","1008-1019","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT ISSN: 0270-5257 Type: Proceedings Paper","","","","decision-making; Python; causal extraction; heuristics; Open Source Software Development (OSSD); rationale; Rationale Miner","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To estimate whether a state ofsocio-technical congruenceis achieved, which is associated with software quality and project success, we assess the alignment of collaboration and communication in such software projects in terms ofcoordination requirements. By means of an empirical study on a substantial set of large-scale open-source software projects-the development histories of all projects sum up to over 180 years-we aim at shedding light on this issue. To this end, to take a more semantic view on this phenomenon in comparison to previous work, we do not only identify coordination requirements arising from files and functions only, but also those arising from features. We found that open-source developers fulfill coordination requirements intentionally, but mostly those coordination requirements that arise from coupled source-code artifacts, while they resolve simpler ones independently. Furthermore, neither of the considered abstraction levels of source-code artifacts (files, functions, features) is more suitable to construct coordination requirements with respect to their fulfillment. This finding strongly indicates that features do not play an as important role in the development process as expected and commonly believed by the research community in the area of feature-oriented and feature-driven development. Finally, we identified notable evolutionary trends in the fulfillment of coordination requirements and showed that far-reaching social events (such as organizational issues) have a huge impact on their fulfillment, both negatively and positively. The key findings of our empirical study are that socio-technical relations are important to understand open-source development communities and that the incorporation of different abstraction levels for developer collaboration does yield important insights to further improve the evolution in open-source software projects.","2020-11","2025-04-25 15:54:14","2025-04-25 15:54:14","","4379-4426","","6","25","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Socio-technical congruence; Codeface; Configurable systems; Coordination requirements; Coronet; Feature-oriented software development; Features; Open-source software systems; Social-network analysis; Software product lines","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 %, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 %. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic. These insights provide various stakeholders, including individuals, organizations, and policymakers, with vital knowledge to prepare for future disruptions, foster sustainable resilience, and adeptly navigate the evolving landscape of remote work in a postpandemic world.","2023-12","2025-04-25 15:54:15","2025-04-25 15:54:15","","","","10","52","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source software; COVID-19; Face-to-face interactions; Lockdown; Work productivity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

CI, in particular, is currently a standard development practice in open source software (OSS) projects. Although it is well-known that OSS contributors have different involvements (e.g., while some developers drive the project, there is a long tail of peripheral developers), little is known about how the contributor's degree of participation can influence the build status of an OSS project. Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result. Our results suggest that there is no representative difference between their build success (they are similar in 85% of the analyzed projects), meaning that being a casual contributor is not a strong indicator for creating failing builds. Also, factors like the size of their contributions and the number of project configurations (jobs) have the potential of impacting the build success.","2017","2025-04-25 15:54:15","2025-04-25 15:54:15","","475-478","","","","","","","IEEE International Working Conference on Mining Software Repositories","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISSN: 2160-1852 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when “simple stupid bugs” were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub. Leveraging a statistical survival model and other non-parametric statistical tests, we found that there were two main categories of categorical variables that affect a bug's life; Time Factors and Author Factors. We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time. These findings will provide vital insight to help the open-source community mitigate the abundance of code and can be used in future research to aid in bug-finding programs.","2023-03","2025-04-25 15:54:15","2025-04-25 15:54:15","","","","5","13","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","survival analysis; bug fixes; one-line bugs; statistical analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

EBA involves the use of psychometric instruments to gather data that can inform clinical decision-making, inform policymakers, and serve as a basis for research and quality management. Despite its potential, EBA is often hindered by barriers such as workload and cost, leading to its underutilization. Regarding low- and middle-income countries (LMIC), the implementation of EBA is recognized as a key strategy to address and close the prevalent mental health treatment gap.To simplify the application of EBA including in LMIC, an international team of researchers and practitioners from Tanzania, Kosovo, Chile, and Switzerland developed the Mental Health Information Reporting Assistant (MHIRA). MHIRA is an open-source electronic health record that streamlines EBA by digitising psychometric instruments and organising patient data in a user-friendly manner. It provides immediate and convenient reports to inform clinical decision-making.The current article provides a comprehensive overview of the features and technical details of MHIRA, as well as insights from four implementation scenarios. The experience gained during the implementations as well as the user-feedback suggests that MHIRA has the potential to be successfully implemented in a variety of clinical contexts and simplify the use of EBA. However, further research is necessary to establish its potential to sustainably transform healthcare services and impact patient outcomes.In conclusion, MHIRA represents an important step in promoting the widespread adoption of EBA in mental health.

However, these infrequent volunteers contribute to the sustainability of FLOSS projects, and should ideally be encouraged to continue participating, even if they cannot be persuaded to contribute regularly. Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature. Also, episodic volunteers make a wide range of value-added contributions other than code, and they should neither be expected nor coerced into becoming habitual volunteers.","2020-09-01","2025-04-25 15:54:15","2025-04-25 15:54:15","","962-980","","9","46","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","Open source software; free software; open source software; Task analysis; Community management; Companies; Sustainable development; Lenses; episodic volunteering; peripheral developer","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities. (C) 2013 The Authors. Published by Elsevier Inc.

Although some of the hosted projects are growing and have many developers, most projects are organized by a few developers and face difficulties in terms of sustainability. OSS projects depend mainly on volunteer developers, and attracting and retaining these volunteers are major concerns of the project stakeholders. To investigate the population structures of OSS development communities in detail and conduct software analytics to obtain actionable information, we apply a demographic approach. Demography is the scientific study of population and seeks to identify the levels and trends in the size and components of a population. This paper presents a case study, investigating the characteristics of the population structures of OSS projects on GitHub, and shows population projections generated with the well-known cohort component method. We found that there are four types of population structures in OSS development communities in terms of experiences and contributions. In addition, we projected the future population accurately using a cohort component population projection method. This method predicts a population of the next period using a survival rate calculated from past population. To the best of our knowledge, this is the first study that applied demography to the field of OSS research. Our approach addressing OSS-related problems based on demography will bring new insights, since studying population is novel in OSS research. Understanding current and future structures of OSS projects can help practitioners to monitor a project, gain awareness of what is happening, manage risks, and evaluate past decisions.","2016-05","2025-04-25 15:54:15","2025-04-25 15:54:15","","1304-1315","","5","E99D","","","","","","","","","","English","","","","","","","Place: KIKAI-SHINKO-KAIKAN BLDG, 3-5-8, SHIBA-KOEN, MINATO-KU, TOKYO, 105-0011, JAPAN Publisher: IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG Type: Article","","","","OSS; demography; software development communities; software population pyramids","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we present a novel method to detect, assess and mitigate OSS vulnerabilities that improves on state-of-the-art approaches, which commonly depend on metadata to identify vulnerable OSS dependencies. Our solution instead is code-centric and combines static and dynamic analysis to determine the reachability of the vulnerable portion of libraries used (directly or transitively) by an application. Taking this usage into account, our approach then supports developers in choosing among the existing non-vulnerable library versions.

For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.","2010","2025-04-25 15:54:15","2025-04-25 15:54:15","","","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","ISSN: 1063-6773 Type: Proceedings Paper","","","","software metrics; software quality; open-source software; Software maintenance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, even after 20 years of intense research in this field, perfusion imaging still remains a research tool without a broad clinical usage. One problem is the lack of standardization in technical aspects which have to be considered for successful quantitative evaluation; the second problem is a lack of tools that allow a direct integration into the diagnostic workflow in radiology. Results: Five compartment models, namely, a one compartment model (1CP), a two compartment exchange (2CXM), a two compartment uptake model (2CUM), a two compartment filtration model (2FM) and eventually the extended Toft's model (ETM) were implemented as plugin for the DICOM workstation OsiriX. Moreover, the plugin has a clean graphical user interface and provides means for quality management during the perfusion data analysis. Based on reference test data, the implementation was validated against a reference implementation. No differences were found in the calculated parameters. Conclusion: We developed open source software to analyse DCE-MRI perfusion data. The software is designed as plugin for the DICOM Workstation OsiriX. It features a clean GUI and provides a simple workflow for data analysis while it could also be seen as a toolbox providing an implementation of several recent compartment models to be applied in research tasks. Integration into the infrastructure of a radiology department is given via OsiriX.

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for-profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 15:54:15","2025-04-25 15:54:15","","369-402","","2","30","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","software development; open source software; metaphor; postcolonialism; Third Design Space; third space","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In stark contrast to the experimental progress, quantitative analysis of GUV microscopy images has received much less attention. Currently, most analysis is performed either manually or with custom-made scripts, which makes analysis time-consuming and results difficult to compare across studies. To make quantitative GUV analysis accessible and fast, we present DisGUVery, an open-source, versatile software that encapsulates multiple algorithms for automated detection and analysis of GUVs in microscopy images. With a performance analysis, we demonstrate that DisGUVery's three vesicle detection modules successfully identify GUVs in images obtained with a wide range of imaging sources, in various typical GUV experiments. Multiple predefined analysis modules allow the user to extract properties such as membrane fluorescence, veside shape, and internal fluorescence from large populations. A new membrane segmentation algorithm facilitates spatial fluorescence analysis of nonspherical vesicles. Altogether, DisGUVery provides an accessible tool to enable high-throughput automated analysis of GUVs, and thereby to promote quantitative data analysis in synthetic cell research.","2023-01-20","2025-04-25 15:54:16","2025-04-25 15:54:16","","120-135","","1","12","","","","","","","","","","English","","","","","","","Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC Type: Article","","","","open-source software; bottom-up reconstitution; giant unilamellar vesicles; image analysis; object detection; synthetic cell","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

E.","Motivating the contributions: An Open Innovation perspective on what to share as Open Source Software","JOURNAL OF SYSTEMS AND SOFTWARE","","0164-1212","10.1016/j.jss.2017.09.032","","Open Source Software (OSS) ecosystems have reshaped the ways how software-intensive firms develop products and deliver value to customers. However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm's practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems. (C) 2017 The Authors.

Mentoring allows contributors to improve their technical skills and learn about the protocols and cultural norms of the project. However, mentoring has its challenges: mentors sometimes feel unappreciated, and mentees may have mismatched interests or lack interpersonal skills. Existing research has investigated the different challenges of mentoring in different OSS contexts, but we lack a holistic understanding. Objective: A comprehensive understanding of the current practices and challenges of mentoring in OSS is needed to implement appropriate strategies to facilitate mentoring. Method: This study presents a systematic literature review investigating how literature has characterized mentoring practices in OSS, including their challenges and the strategies to mitigate them. We retrieved 232 studies from four digital libraries. Out of these, 21 were primary studies. Using this, we performed backward and author snowballing, adding another 27 studies. We conducted a completeness check by reviewing the references of the 4 most relevant primary studies, which resulted in us adding 1 additional study. We then conducted a full-text review and evaluated the studies using a set of criteria; as a result, 10 papers were excluded. We then employed an open-coding approach to analyze, aggregate, and synthesize the selected studies. Results: We reviewed 39 studies to investigate the different facets of mentoring in OSS, encompassing motivations, goals, channels, and contributor dynamics. We then identified 13 challenges associated with mentoring in OSS, which fall into three categories: social, process, and technical. We also present a quick-reference strategy catalog to map these strategies to challenges for mitigation. Conclusions: Our study serves as a guideline for researchers and practitioners about mentoring challenges and potential strategies to mitigate these challenges.","2024-07","2025-04-25 15:54:16","2025-04-25 15:54:16","","","","","171","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source; Mentoring; Literature review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.","2021-09-25","2025-04-25 15:54:16","2025-04-25 15:54:16","","","","1","13","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Deep learning; De novo drug design; Graphical user interface; Molecule generation; Web application","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially influence how a new OSS project chooses among such licenses and how the experiences of the project manager of a new OSS project with particular licenses affects its susceptibility to this social influence. We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Our results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its inter-project social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. We also find that managers of new projects who have been members of more successful prior OSS projects and who have greater depth and diversity, of experience in the OSS community are less susceptible to social influence. Finally, we find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license. These results have implications for research on innovation adoption and diffusion, open source software licensing, and the governance of economic exchange.","2013-09","2025-04-25 15:54:16","2025-04-25 15:54:16","","539-560","","3","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","social networks; social influence; innovation adoption and diffusion; open source software license","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By knowing this licensing effect through scientific publications and their experience, project managers became able to act strategically, loosening up the restrictions associated with their source code due to sponsor interests, for example; or the contrary, tightening restrictions up to guarantee source code openness, adhering to the “forever free” strategy. But, have project managers behaved strategically like that, changing their projects license? Up to this paper, we did not know if and what types of changes in these legal allowances project managers have made and, more importantly, whether such managerial interventions are associated with variations in intervened project attractiveness (i.e., related to their numbers of web hits, downloads and members). This paper accomplishes these two goals and demonstrates that: 1) managers of free and open source software projects do change the distribution rights of their source code through a change in the (group of) license(s) adopted; and 2) variations in attractiveness are associated with the strategic choice of a licensing schema. To reach these conclusions, a unique dataset of open source projects that have changed license was assembled in a comparative form, analyzing intervened projects over its monthly periods of different licenses. Based on a sample of more than 3500 active projects over 44 months obtained from the FLOSSmole repository of Sourceforge.net, 756 projects that had changed their source code distribution allowances and restrictions were identified and analyzed. A dataset on these projects' type of changes was assembled to enable a descriptive and exploratory analysis of the types of license interventions observed over a period of almost four years anchored on projects' attractiveness. More than 35 types of interventions were detected. The results indicate that variations in attractiveness after a license intervention are not symmetric; that is, if a change from license schema A to B is beneficial to attractiveness, a change from B to A is not necessarily prejudicial. This and other interesting findings are discussed in detail. In general, the results here reported support the current literature knowledge that the restrictions imposed by the license on the source code distribution are associated with market success vis-a-vis project attractiveness, but they also suggest that the state-of-the-science is superficial in terms of what is known about why these differences in attractiveness can be observed. The complexity of the results indicates to free software managers that no licensing schema should be seen as the right one, and its choice should be carefully made, considering project strategic goals as perceived relevant to stakeholders of the application and its production. These conclusions create awareness of several limitations of our current knowledge, which are discussed along with guidelines to understand them deeper in future research endeavors.","2017-08-07","2025-04-25 15:54:17","2025-04-25 15:54:17","","","","","8","","","","","","","","","","English","","","","","","","Place: Av.

Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.","2006-06","2025-04-25 15:54:17","2025-04-25 15:54:17","","126-144","","2","17","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source; software development; success; software licensing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding contributor behavior within large Free/Open Source Software projects - A socialization perspective","JOURNAL OF STRATEGIC INFORMATION SYSTEMS","","0963-8687","10.1016/j.jsis.2017.03.001","","Attracting new contributors is a necessary but not a sufficient condition, to ensure the survival and long-term success of Free/Open Source Software (FOSS) projects. The well-being of a FOSS project depends on the turning of project newcomers into `good contributors' that is to say into individuals that substantially contribute to the project - but also that perform citizenship behaviors that protect and nurture its community. This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness. Theoretical and practical implications are discussed. (C) 2017 Elsevier B.V.

Design/methodology/approach This study focuses on dependencies using three network metrics - degree centrality, betweenness centrality and closeness centrality - in developer and module networks. A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks. Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.

The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the “institutional design” of the ASF could aid in producing the OSS public good by providing services that projects require.","2022","2025-04-25 15:54:17","2025-04-25 15:54:17","","64-77","","1","16","","","","","","","","","","English","","","","","","","Place: Unit 3N, 6 Osborn Street, LONDON, E1 6TD, ENGLAND Publisher: UBIQUITY PRESS LTD Type: Article","","","","institutional analysis; open source software; commons; public goods; cost-benefit analysis; common-pool resource; policy analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help “transfer” their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more “open” and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as “porting,” the “kernel,” “copyleft,” and “forking” that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.","2012","2025-04-25 15:54:17","2025-04-25 15:54:17","","234-243","","3","71","","","","","","","","","","English","","","","","","","Place: 3000 UNITED FOUNDERS BLVD, STE 148, OKLAHOMA CITY, OK 73112 USA Publisher: SOC APPLIED ANTHROPOLOGY Type: Article","","","","open source software; community-based natural resource management; transferability; watershed management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been in-stitutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous se-curity in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed secu-rity controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption en-ables businesses to deliver time-to-market security ready applications and services with accelerated ve-locity and sustainable agility in a cost-effective way.

This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader.

Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a “safety net” for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and “living” design documentation. Rapid-cycle development or “agile” methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as “executable requirements.” Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the “executable requirements” are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.","2018-06","2025-04-25 15:54:17","2025-04-25 15:54:17","","80-90","","2","6","","","","","","","","","","English","","","","","","","Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC Type: Article","","","","agile methods; clinical decision support systems; electronic health records; software validation; software verification; test driven development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study.

On these platforms, various information is obtained from developer activities that can then be used as developer metrics to solve a variety of challenges. In this study, we proposed new developer metrics extracted from the issue, commit, and pull request activities of developers on GitHub. We created developer metrics from the individual activities and combined certain activities according to some common traits. To evaluate these metrics, we created an item-based project recommendation system. In order to validate this system, we calculated the similarity score using two methods and assessed top-n hit scores using two different approaches. The results for all scores with these methods indicated that the most successful metrics were binary_issue_related, issue_commented, binary_pr_related, and issue_opened. To verify our results, we compared our metrics with another metric generated from a very similar study and found that most of our metrics gave better scores that metric. In conclusion, the issue feature is more crucial for GitHub compared with other features. Moreover, commenting activity in projects can be equally as valuable as code contributions.

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors (”problem solvers”) tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs (”problems”) tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between “core” and “peripheral” members identified exclusively on the basis of their individual level of contribution to the project.

Past work has focused on characterizing the main differences between OSS and traditional forms of software RE. In this effort we focus on differences in RE activity in OSS. RE is characterized as a socio-technical distributed cognitive (DCog) activity where multiple actors deploy artifacts to `compute' requirements. To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community. Finally the velocity of change in technological requirements influence the project's documentation practices of requirements with the level of design consistency desired in the end product influencing the decision-making channels used in the development endeavor.","2016","2025-04-25 15:54:18","2025-04-25 15:54:18","","4982-4991","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Pacific Res Inst Informat Syst & Management; Univ Hawaii Manoa, Shidler Coll Business, Dept IT Management; IBM; Provalis Res; Int Soc Serv Innovat Profess; Teradata; Univ Network; IEEE Comp Soc ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Bui, TX; Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Chemical processes are invariably described by non-linear equations such as chemical reaction kinetics, flow-pressure relationships and physical properties. Dynamic simulation of such systems involves the solution of sets of non-linear differential and algebraic equations. There is also uncertainty associated with the model equations themselves (model uncertainty), their parameters (parametric uncertainty) and the inputs into the model (input uncertainty). Tools that aid chemical engineers in the solution of these problems have been successfully commercialised and enjoy a measure of success, although the adoption of dynamic and stochastic simulation packages is lagging behind the steady-state flowsheeting tools. Commercial software solutions can be prohibitively expensive in addition to confining users to adhere to proprietary standards. The Free Software and Open Source movements have made inroads into providing non-proprietary alternatives to many commercial software packages, which has encouraged the adoption of open standards. This work presents a framework for the development of stochastic dynamic simulations of chemical processes using only free and open source software. The large problem of stochastic dynamic simulation has been broken down into stages: 1. Input modelling using Markov chain models trained on process data or seeded by hand in addition to stationary distribution models. This enables dynamic scenarios to be handled with the minimum of special case code generation. 2. Process modelling using an object-oriented approach in the Modelica language. Modelica has an actively developed open source implementation called OpenModelica and is an open standard modelling language. 3. Monte Carlo simulation using extensions to the OpenModelica compiler that ease parallel simulations 4. Postprocessing, including visualisation and statistical analysis. Statistics that are generated can be used for control evaluation purposes. The Tennessee-Eastman challenge process is used to illustrate its capabilities.","2011","2025-04-25 15:54:18","2025-04-25 15:54:18","","146-150","","","29","","","","Computer-Aided Chemical Engineering","","","","ELSEVIER SCIENCE BV","SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS","English","","","","","","","ISSN: 1570-7946 Type: Proceedings Paper","","","","Open Source; Segmentation; stochastic modelling","","Pistikopoulos, EN; Georgiadis, MC; Kokossis, AC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is debatable whether they should be used in open-source software (OSS) initiatives. There are studies examining the SRGMs' applicability in the OSS setting, but their scope is constrained by the models and projects they take into account, which could result in inconsistent findings. In this paper, the available SRGMs in the backdrop of OSS have been scrutinized and limitations have been identified. To address these limitations, a modification to the SRGMs using fuzzy neural networks (FNNs) has been proposed. In this paper, various SRGMs have been reviewed and sharp distinction among the same has been made, taking their respective failure intensity and mean value function under consideration. Through the failure intensity of software, it becomes a cakewalk to identify and predict the faults even before they actually arise and necessary and timely action may be initiated. After duly considering the review and contrast between the factors, a FNN model has been suggested for determination of software reliability differing with values of failure intensity and mean value function. First software failure data from a number of open-source software (OSS) projects have been gathered as part of the methodology used to modify traditional SRGMs. The proposed model gives out a high reliability rate and a low failure intensity. The most important factor is that it caters for the faults that are current and are being faced by the users on day to basis currently. It was found that the proposed model has a high success rate with the value of 82.6950937% which is considered as a successful result for software. The suggested FNN model may have a potential impact on the field of software reliability since FNN can handle the ambiguity and imprecision in the software failure data that are typical in open-source projects.","2023-07-04","2025-04-25 15:54:18","2025-04-25 15:54:18","","","","","","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article; Early Access","","","","Software reliability; Software reliability growth model; Failure intensity function; Fuzzy neural network (FNN); Logistic growth; Mean value function","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These volunteers, commonly referred to as OSS project community, serve as the foundation of the OSS project, fostering its creation and sustenance and providing long-term support. The quality and sustainability of the OSS project is reliant upon the development and structure of the self-governing community. When a business organization plans to acquire an OSS solution, it not only takes into consideration the factors such as reliability, security, and scalability but also attaches significant importance to the likelihood of the OSS project being maintained and supported in the future so that it can rely on it as a stable and secure technology solution. Modern cloud-based software hosting platforms, such as GitHub, offer a range of options for automatically and freely accessing the complete development history of millions of OSS projects. This easy availability of detailed development history has enabled researchers to analyze and draw quantitative and scientific inferences about the quality of an OSS project which generally involves assessing three aspects, namely, software product, development process, and project community. With focus on project community part, a Framework for Assessment and Ranking of OSS Community is being presented in the current research work, following a detailed examination of the largest source code hosting and project collaboration platform, GitHub. Technique for Order of Preference by Similarity to Ideal Solution from Multi-Criteria Decision-Making toolkit has been utilized for assessing the quality of the project community. The framework has been validated by applying it on nine OSS projects and comparing the results with the outcomes obtained through an existing OSS evaluation methodology. The comparative analysis demonstrated that the proposed framework aligns with the aforementioned evaluation methodology while offering an opportunity for in-depth analysis on the dynamics of volunteer communities, which is lacking in previous evaluation methods. These insights can prove valuable for both potential adopters and project maintainers, aiding them in making informed strategic decisions. Framework for Project Community Assessment and Ranking follows a phased approach where first phase involves OSS project identification, second phase defines assessment criteria, in third phase data is fetched, stored and metrics are computed; and the last phase involves final Quality Assessment and Ranking. The framework will aid both corporate entities and individual practitioners in identifying an open source project with a robust volunteer community capable of producing a product of exceptional quality.image","2024-07","2025-04-25 15:54:18","2025-04-25 15:54:18","","","","7","36","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","open source software; software quality; multi-criteria decision-making; project community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An increasing rate of urban growth and urban sprawl could induce changes in land use as well as land transformation. However, accurate and up-to-date information about LULC is required for providing better understanding and assessing the environmental consequences of such changes. In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80% and 80.40% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification. To summarize, ArcGIS and QGIS software are reliable to be used in the land cover classification.","2020","2025-04-25 15:54:18","2025-04-25 15:54:18","","","","","540","","","","IOP Conference Series-Earth and Environmental Science","","","","IOP PUBLISHING LTD","DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND","English","","","","","","","Backup Publisher: Inst Geospatial & Remote Sensing Malaysia; Univ Putra Malaysia; Sc & Technol Res Inst Def; Univ Teknologi Malaysia; Univ Utara Malaysia; Int Islam Univ Malaysia; Forest Res Inst Malaysia; GIS Innovat Sdn Bhd; GPS Lands M Sdn Bhd; IEEE Geoscience & Remote Sensing Soc, Malaysia Chapter ISSN: 1755-1307 Type: Proceedings Paper","","","","","","Omar, H; Shariff, ARM; Sathyamoorthy, D; Mat, RC; Tarmidi, Z; Ismail, MH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.","2021-12-02","2025-04-25 15:54:18","2025-04-25 15:54:18","","","","12","23","","","","","","","","","","English","","","","","","","Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC Type: Article","","","","sustainability; open-source software; cancer informatics; financial model; licensing model; product management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Urban environments must therefore be at the heart of any global energy transition. Furthermore, land availability is a limiting factor for renewable deployment and rooftop PV thus offers a clear advantage. This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 % of the total electricity consumption of the city and where 50 % of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies. Additionally, this article provides valuable information, such as rooftop usability factors, and an overall reduction factor (CT), useful to extend RPVP assessment to larger areas using constant value methods.","2025-03-15","2025-04-25 15:54:18","2025-04-25 15:54:18","","","","","331","","","","","","","","","","English","","","","","","","Place: PO BOX 564, 1001 LAUSANNE, SWITZERLAND Publisher: ELSEVIER SCIENCE SA Type: Article","","","","Open-source software; Energy return on investment (EROI); Geographic information systems (GIS); Net energy analysis (NEA); Photovoltaic potential; Rooftop photovoltaics (RPV)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On this rationale, this study was carried out to explore the applicability of the concept of converging `Free and Open Source Software (FOSS)' to promote sustainable knowledge sharing amongst the agricultural communities in Sri Lanka. A multi-stage community consultative process with a set of designated officials (”Sponsors”) and a series of semi-structured questionnaire survey with a cross section of smallholder agriculture farmers (n=246), were carried out in the Batticaloa, Kurunegala and Puttalam districts to gather the baseline data. This was followed by a number of field experiments (”Campaigns”) with the farmers (n=340) from same geographical areas. The two FOSS, namely: (1) “FrontlineSMS” for `Text Messaging' and (2) “FreedomFone” for `Interactive Voice Responses', were applied to evaluate the effectiveness of knowledge sharing within the farming communities. It was found that FOSS intervention increases the `Text messaging' and `Voice Call' usage in day-to-day agricultural communication by 26 and 8 percent, respectively. The demographic factors like age and educational level of the farmers have a positive influence on the knowledge sharing process. And also the `Mobile Telephony' was the most extensive mode of communication within the communities. The outcome of analysis, as a whole, implies that, with a fitting mechanism in place, this approach can be promoted as a “drive for positive changes” in agriculture-based rural communities in developing countries like Sri Lanka, and those in South and East Asia with similar socioeconomic and cultural perspectives.","2017","2025-04-25 15:54:19","2025-04-25 15:54:19","","351-359","","2","111","","","","","","","","","","English","","","","","","","Place: VIA ANTONIO COCCHI 4, FLORENCE, 50131, ITALY Publisher: AGENZIA ITALIANA COOPERAZIONE SVILUPPO-ITALIAN DEV COOP AGENCY Type: Article","","","","FOSS; Information; Knowledge sharing; Agricultural community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

SU2 is one of these open -source tools. Unlike other open -source alternatives, SU2 is equipped with boundary condition types, solvers and methods that are especially developed for the analysis and design of turbomachinery. The aim of this work is to explore and investigate the capabilities of SU2 in the prediction of performance parameters of radial compressors. Two different single stage shrouded compressor geometries, one with a vaneless diffuser and the other with a vaned diffuser have been investigated with steady state CFD. The compressors were designed by MAN Energy Solutions Schweiz AG. Computational results with SU2 showed a satisfactory agreement with both the experimental data and reference CFD solutions obtained with Fidelity Flow, which is formerly known as Numeca Fine TURBO. Only at the relatively higher mass flow rates the difference between references and SU2 were higher compared to other operating points. After performance parameters were successfully calculated with SU2, the optimization tools that come with SU2 were also used. A 2D adjoint optimization study on the vane of the vaned diffuser was carried out. The study was carried out at a single operating point that is close to choke conditions. The loss generated by the large separated flow region at the suction side of the diffuser vane was reduced by 0.55 % in the optimized geometry using minimal modifications on the existing vane geometry to keep the performance of the compressor intact at other operating points. However, the resulting modification increased the total pressure loss by 0.86 % at one of the design operating points. This performance penalty could be due to the discontinuity in the vane geometry generated by the optimizer. Overall, the study shows that SU2 has the basic numerical schemes and models that are required for the analysis of radial turbomachinery flows and geometry optimization.","2023","2025-04-25 15:54:19","2025-04-25 15:54:19","","233-242","","2","43","","","","","","","","","","English","","","","","","","Place: TIBTD MAKINA MUHENDISLIGI BOLUMU ODTU, ANKARA, 06531, Turkiye Publisher: TURKISH SOC THERMAL SCIENCES TECHNOLOGY Type: Article","","","","Optimization; Open-source; Compressor; Computational Fluid Dynamics; SU2; Turbomachinery","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio [finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing.

In these studies, segmentation and quantification of myocardial infarct lesion are often performed with a commercial software or an in-house closed-source code development thus creating a barrier for reproducible research. This paper introduces CMRSegTools: an open-source application software designed for the segmentation and quantification of myocardial infarct lesion enabling full access to state-of-the-art segmentation methods and parameters, easy integration of new algorithms and standardised results sharing. This post-processing tool has been implemented as a plug-in for the OsiriX/Horos DICOM viewer leveraging its database management functionalities and user interaction features to provide a bespoke tool for the analysis of cardiac MR images on large clinical cohorts. CMRSegTools includes, among others, user-assisted segmentation of the left-ventricle, semi- and automatic lesion segmentation methods, advanced statistical analysis and visualisation based on the American Heart Association 17-segment model. New segmentation methods can be integrated into the plug-in by developing components based on image processing and visualisation libraries such as ITK and VTK in C++ programming language. CMRSegTools allows the creation of training and testing data sets (labeled features such as lesion, microvascular obstruction and remote ROI) for supervised Machine Learning methods, and enables the comparative assessment of lesion segmentation methods via a single and integrated platform. The plug-in has been successfully used by several CMR imaging studies.","2022-09-13","2025-04-25 15:54:19","2025-04-25 15:54:19","","","","9","17","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 15:54:19","2025-04-25 15:54:19","","119-139","","1","39","","","","","","","","","","English","","","","","","","Place: Floor 5, Northspring 21-23 Wellington Street, Leeds, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Open source software; Motivations; Open content; Social Q&A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In Indonesia alone, 25% of South East Asia's mangroves are at a risk. The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was “Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang” held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes.

There are several factors that affect a developer's decision to join an OSS project, yet little research examined the influence of third-party assessments on a developer's intention to join a project. Drawing on signaling theory, this manuscript explores how third-party assessment can influence a developers' decision to join an OSS project. In order to test it, vignette survey study was conducted manipulating reputation, development experience, and a number of current OSS projects of existing developers in the OSS project. The findings suggest that all three signals have a positive influence on developer's decision to join the OSS project. This suggests that projects seeking to expand the number of contributing developers should consider offering information about its “star developers”.","2018","2025-04-25 15:54:19","2025-04-25 15:54:19","","","","","","","","","","","","","ASSOC INFORMATION SYSTEMS","P.O.

Students use OSS applications and systems in their courses on programming, operating systems, DBMS. web development to name but a few. Studying OSS projects from both a product and a process view also forms part of the software engineering curriculum at various universities. Many students have taken part in OSS projects as well as developers. At the University of Lincoln, under the Undergraduate Research Opportunities Scheme (UROS), undergraduate student researchers have the chance to work over the summer embedded within an existing research centre on a UROS project. Here two such projects within the Centre for Research in Open Source Software (CROSS) are described: Collaborative Development for the XO Laptop (CODEX) and Software Modularity in Open Source Software (SoMOSS). The CODEX project focused on creating resources to support students undertaking software application development for the XO laptop, and the SoMOSS project focused on architectural studies of OSS instant messaging software. Both projects achieved successful research outcomes; more importantly, both student researchers benefited directly from the encouragement and concrete assistance that they received through interaction with the wider OSS research community. Both projects are ongoing and present further research opportunities for students.","2009","2025-04-25 15:54:19","2025-04-25 15:54:19","","340-350","","","299","","","","International Federation for Information Processing","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","Backup Publisher: IFIP WG 2 13 ISSN: 1571-5736 Type: Proceedings Paper","","","","","","Boldyreff, C; Crowston, K; Lundell, B; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of biological sciences, information commons, such as public biobanks and free/libre open source software (FLOSS), are of paramount importance for both research and the bioeconomy. In a time of digitalization, however, information commons are vulnerable to violations, such as the free-rider problem, that render the commons unsustainable. Consequently, it has been argued that the enclosure of the informational common resources is the only means to effectively exploit them. Given the social and economic importance of the information commons, the new digital environment in biology and health requires governance innovation that will regulate the social embedding of the commons and their relationship to the free market, that is, a new political economy is needed. In this context, the need for a core common infrastructure, stretching from the physical to the logical and content layer of the information environment, that will guarantee the protection of the commons from both violations and enclosures, has been highlighted. Focusing on the interaction between two biological/bioinformatics commons, namely public biobanks and the FLOSS, we have set up an ecosystem relying on a blockchain technology. The proposed governance mechanism protects the information commons from the free-rider problem and guarantees their sustainability without hampering their operational framework. Our model demonstrates the interdependence and protection of the information commons not as an abstract theoretical exercise, but rather as a physical reality on the digital ontological matrix.","2020-05-01","2025-04-25 15:54:20","2025-04-25 15:54:20","","278-285","","5","24","","","","","","","","","","English","","","","","","","Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC Type: Article","","","","digitalization; political economy; blockchain; free; libre open source software; public biobanks; the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Key considerations when considering prognostic enrichment include: clinical trial sample size; the number of patients one must screen to enroll the trial; and total patient screening costs and total per-patient trial costs. The Biomarker Prognostic Enrichment Tool for Survival Outcomes (BioPETsurv) is a suite of methods for estimating these elements to evaluate a prognostic enrichment biomarker and/or plan a prognostically enriched clinical trial with a time-to-event primary endpoint. BioPETsurv allows investigators to analyze data on a candidate biomarker and potentially censored survival times. Alternatively, BioPETsurv can simulate data to match a particular clinical setting. BioPETsurv's data simulator enables investigators to explore the potential utility of a prognostic enrichment biomarker for their clinical setting. Results demonstrate that both modestly prognostic and strongly prognostic biomarkers can improve trial metrics such as reducing sample size or trial costs. In addition to the quantitative analysis provided by BioPETsurv, investigators should consider the generalizability of trial results and evaluate the ethics of trial eligibility criteria. BioPETsurv is freely available as a package for theRstatistical computing platform, and as a webtool at www.prognosticenrichment.com/surv.","2020-09-18","2025-04-25 15:54:20","2025-04-25 15:54:20","","","","9","15","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although open source software (OSS) is not a new idea, several product development companies that operate in a market-driven context have started to use open source solutions as core software components in their products. Adopting open source core components implies a lower degree of control over software development and increased business risk associated with integrating differentiating contributions into the core release stream. Whether and how to adjust the current requirements management practices after the adoption of OSS components to fully benefit from the concept of open innovation has not yet been empirically explored. We outline experiences and challenges related to leveraging open innovation via engaging in OSS identified during 19 interviews with practitioners occupying different roles in the requirements management process at a large company followed by four validation interviews with other practitioners.

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.","2023","2025-04-25 15:54:20","2025-04-25 15:54:20","","180-190","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Elsevier; Digital Govt Soc; Gdansk Univ Technol, Res Univ Excellence Initiat; Fdn Lech Walesa Inst; Marshal Pomorskie Voivodeship; President City Gdansk; Rector Gdansk Univ Technol; Gdansk Univ Technol, Fac Management & Econ Type: Proceedings Paper","","","","GitHub; open source software; government; barriers; benefits; citizen engagement; evidence","","Sabatini, N; Hagen, L; Liao, HC; Cid, DD","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While 3DP has gained tremendous popularity, it remains a daunting and perceptibly time-consuming process for the inexperienced user, with most turning to commercially printed products. Commercial vendors are expensive. We propose that 3DP is feasible for the inexperienced user with the appropriate knowledge and tools.Methods: A 3DP protocol was created for model design and printing using open-source software and a low-cost desktop printer. It was betatested by 3 inexperienced users. The fidelity of the protocol was then tested in direct comparison to industry models made for 3 patients undergoing mandibular distraction osteogenesis, using standard cephalometric measurements.Results: All inexperienced testers were able to successfully create a 3D model using the easy-to-follow protocol without the use of any other resources. The models were created in a mean time of 170 minutes. All cephalometric measurements on the open-source printed models were equal to within 0.5 to 1.0 mm of the respective industry models.Conclusions: As the 3DP process is simplified and desktop printers and materials become more affordable, we anticipate that its implementation will become more commonplace. We describe a step-by-step, protocol using open-source software and affordable materials to create 3D models.","2022-03","2025-04-25 15:54:20","2025-04-25 15:54:20","","66-73","","1","3","","","","","","","","","","English","","","","","","","Place: 2455 ℡LER RD, THOUSAND OAKS, CA 91320 USA Publisher: SAGE PUBLICATIONS INC Type: Article","","","","open source; 3D printing; craniofacial; stereolithography","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage. The empirical investigation in this paper shows that the switching points of stages have meaningful associations with the release dates.","2014","2025-04-25 15:54:20","2025-04-25 15:54:20","","207-212","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nowadays, it is becoming challenging to procure bone legally, resulting in medical students' inadequacy of bone. Plaster -of -Paris or resin bone models sold on the market are less detailed than real bones. Aims and objectives This study aims to create a three-dimensional (3D)-printed human bone model with free, open-source software and fused deposition modelling (FDM) 3D printers, compare its accuracy with the original bones and validate it with a textbook description. Methods Scapula and hip bone models were produced using open-source software 3D Slicer from computed tomography (CT) data from the “New Mexico Decedent Image Database”. After automated segmentation, bones were edited manually with tools in a 3D Slicer (https://www.slicer.org/) and Meshmixer software (Autodesk Inc., San Rafael, California, United States) and 3D bone models were printed using polylactic (PLA) filament. Results and discussions 3D digital models of both bones were successfully created with the maximum possible accuracy with an FDM 3D printer. A 3D digital replica of the scapula obtained after segmentation retained most anatomical features except for the glenoid cavity, as the head of the humerus obscured the glenoid cavity. The 3D digital skeleton of the hip bone retained all anatomical features except articulating surfaces, such as the acetabulum and auricular surface ilium, which were obscured by the head of the femur and sacrum. A few morphological features of both bones differed from the original dry bone, and a few finer details were unclear in the iliac fossa and ischium. After manual editing and post -processing, the final physical model obtained has all the features.

This paper seeks to broaden the research on virtual communities by applying the theory of competency rallying (TCR) in a longitudinal manner to examine the impact of task identification, task assignment, task execution and task management on user interest in open source software (OSS) projects defined by popularity and communication. The aim of this paper is: (I) re-conceptualizing the concept of user interest and broadening our understanding of user interest by incorporating users' post-usage behaviors, (2) examining the effect of various tasks involved in an OSS project's key processes of defect-fixing and feature-enhancement on user interest. The current study found that project popularity is positively influenced by task assignment, task execution and task management. Additionally, user communication was found to be positively impacted by task identification and task execution. The data collected from 1178 OSS projects in a longitudinal manner (at 3 time points over a period of 16 months) confirmed the expectations from TCR and also demonstrated that over time the effects that development of competencies and managing short term cooperative work have on project success might increase, while the impact of identifying market needs and marshalling competencies may not significantly change.

In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere. I argue that these competing views are consequential, for they link technical artifacts and political agents in practice, by way of aspirations, obligations, and forms of authority. Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.","2007-05","2025-04-25 15:54:20","2025-04-25 15:54:20","","211-235","","2","93","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","free and open source software; artifact; Bruno Latour; public sphere theory; socio-technical deliberation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work introduces Dareplane, a modular and broad technology-agnostic open source software platform for brain-computer interface (BCI) research with an application focus on adaptive deep brain stimulation (aDBS). One difficulty for investigating control approaches for aDBS resides with the complex setups required for aDBS experiments, a challenge Dareplane tries to address. Approach. The key features of the platform are presented and the composition of modules into a full experimental setup is discussed in the context of a Python-based orchestration module. The performance of a typical experimental setup on Dareplane for aDBS is evaluated in three benchtop experiments, covering (a) an easy-to-replicate setup using an Arduino microcontroller, (b) a setup with hardware of an implantable pulse generator, and (c) a setup using an established and CE certified external neurostimulator. The full technical feasibility of the platform in the aDBS context is demonstrated in a first closed-loop session with externalized leads on a patient with Parkinson's disease receiving DBS treatment and further in a non-invasive BCI speller application using code-modulated visual evoked potential (c-VEP). Main results. The platform is implemented and open-source accessible on https://github.com/bsdlab/Dareplane. Benchtop results show that performance of the platform is sufficient for current aDBS latencies, and the platform could successfully be used in the aDBS experiment. The timing-critical c-VEP speller could be successfully implemented on the platform achieving expected information transfer rates. Significance. The Dareplane platform supports aDBS setups, and more generally the research on neurotechnological systems such as BCIs. It provides a modular, technology-agnostic, and easy-to-implement software platform to make experimental setups more resilient and replicable.","2025-04-01","2025-04-25 15:54:20","2025-04-25 15:54:20","","","","2","22","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP Publishing Ltd Type: Article","","","","open source software; brain-computer interface; brain-machine interface; c-VEP; closed-loop; deep brain stimulation; electrophysiology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then, it has become practically essential for identifying bacteria in microbiological diagnostic laboratories. In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from. MSProfileR has been developed in the R environment and offers a user-friendly web interface using the R Shiny framework. It is available on Microsoft Windows as a web browser application by simple navigation using the link of the package on Github v.3.10.0. MSProfileR is therefore accessible to non-computer specialists and is freely available to the scientific community. We evaluated MSProfileR using two datasets including exclusively MS spectra from arthropods. In addition to coherent sample classification, outlier MS spectra were detected in each dataset confirming the value of MSProfileR.","2024-06","2025-04-25 15:54:20","2025-04-25 15:54:20","","","","2","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","Github; R package; arthropod vectors; MALDI-TOF MS; quality control; rstudio; Shiny interface","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In that community, companies always play auxiliary roles, and integrate the result of OSS into their business activities. However, in the Eclipse open source software community, the main role of OSS development activities is taken over by companies. The relationship between individuals and companies is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of a company. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify a structure of co-creation in an OSS ecosystem led by companies considering the Eclipse community as one particular case. It also constructs a co-creation process model to promote sustainable development for an OSS ecosystem following two axes 1) value sharing and value acquisition, and 2) quantitative development and qualitative development. Some mechanisms that drive this process are embedded everywhere in the Eclipse ecosystem.","2011","2025-04-25 15:54:20","2025-04-25 15:54:20","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Portland State Univ, Maseeh Coll Engn & Comp Sci, Dept Engn & Technol Management; Portland State Univ, Off Informat Technol; IKON Off Solut Type: Proceedings Paper","","","","","","Kocaoglu, DF; Anderson, TR; Daim, TU","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

Although multitude of studies have provided effective models for OSS sustainability, their practical implications have been lacking because most identified features are not amenable to direct tuning by developers (e.g., levels of communication, number of commits per project). In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed a comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs). The ReACTs are practical advice with specific steps, found in prior work to associate with tangible results. Starting from a set of sustainability-related features, this study contributes 105 ReACTs to the SE community by analyzing 186 published articles. Moreover, this study introduces a newly developed tool (ReACTive) designed to enhance the exploration of ReACTs through visualization across various facets of the OSS ecosystem. The ReACTs idea opens new avenues for connecting SE metrics to actionable research in SE in general.","2024","2025-04-25 15:54:21","2025-04-25 15:54:21","","457-461","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSOFT; Huawei; Technol Innovat Inst; Google; JetBrains; Uber Type: Proceedings Paper","","","","Open Source Software; Sustainability; Literature Review; Research Actionable","","D'Amorim, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ability of the variometric approach to detect short-term dynamic behaviors in real-time mode in applications such as Global Navigation Satellite Systems (GNSS)-seismology and structural health monitoring is demonstrated, the demand for open-source VA software is increasing. However, open-source software that is capable of VA processing in real-time mode based on single- and dual-frequency multi-GNSS observations is scarce. In view of this fact, we have developed an open-source VA processing software called PPPH-VA that can evaluate single- and dual-frequency multi-GNSS observations in real-time mode. PPPH-VA is developed in the MATLAB environment, and it can simultaneously process GPS, GLONASS, Galileo, BeiDou-2, and BeiDou-3 data with the VA technique in real-time mode, employing both single- and dual-frequency observations. We evaluated PPPH-VA using shake table experiments based on real data, and the results demonstrate that it provides high accuracy in terms of detection of dynamic displacements. Toolbox can successfully detect the dominant frequencies of short-term dynamic behaviors and is capable of determining the amplitude values corresponding to the peak frequency at the sub-mm level. Moreover, in the time domain, it can obtain dynamic behaviors with an accuracy of millimeters.","2024-01","2025-04-25 15:54:21","2025-04-25 15:54:21","","","","1","28","","","","","","","","","","English","","","","","","","Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG Type: Article","","","","Open-source software; Dynamic displacement; High-rate; Multi-GNSS; PPPH-VA; Real-time; Variometric approach","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most large and complex software packages partitioned across multiple portals and involve many users - each with their role in the software package; those users have different perspectives on the software package, defined by their knowledge, responsibilities, and commitments. Thus, a multi-perspective approach has been used in usability evaluation to overcome the challenge of inconsistency between users' perspectives; the inconsistency challenge would lead to an ill-advised decision on the selection of a suitable OSS. This study aimed to assist the public and private organizations in evaluating and selecting the most suitable OSS. The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.","2023-01","2025-04-25 15:54:21","2025-04-25 15:54:21","","187-277","","01","22","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","evaluation; selection; open-source software (OSS); benchmarking; BWM; decision matrix; Multi-criteria decision making (MCDM); VIKOR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project's capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of subtopics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance.

Since then countless libraries across the United States have used the program to create online tutorials in order to teach a variety of information literacy skills including how to search databases, how to evaluate websites, how to create better searches, and how to search for medical information. The Guide on the Side was created by a group of University of Arizona librarians in order to replicate the hands-on experience students received when they attended a library session on how to use a research database. Librarians aimed to give students the guided instruction they received in face-to-face sessions. Sophisticated research databases are often difficult for undergraduate students to use, and they need both background knowledge and repeated practice to use a database successfully. With the Guide on the Side, students are presented with authentic tasks and are able to conduct “live” searches as they are guided through the database. Through these activities, they learn how to locate the information they need quickly. Although a valuable and easy to use software program, instructors and librarians are often at a loss for how to create tutorials that are appealing to students and that are aligned with best practices for online instruction. This paper will focus on best practices when using the Guide on the Side. These best practices have been developed by the author and are based on current educational research focused on online instruction and on usability studies conducted using the Guide on the Side. This paper discusses the development of the Guide on the Side, how to download it, and how to implement these best practices in order to create learning experiences for students that are both engaging and effective.","2017","2025-04-25 15:54:21","2025-04-25 15:54:21","","395-400","","","","","","","INTED Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1079 Type: Proceedings Paper","","","","information literacy; guide on the side; library; online instruction; tutorials","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we here propose an information system that facilitates the use of BIM for geo-analysis purposes. BIM4GeoA is a concept for combining existing open source software and open specification for efficient data management and analysis of Building Information within its boarder context. The core components are the spatial database PostgreSQL/PostGIS, the building information server, the industrial foundation class (IFC), the Google Earth 3D viewer, and the existing 3D OGC standard (KML, CityGML). This paper presents the procedure used to enable the development of this new expert system as applied to the context of 3D Web GIS. A thorough analysis of the strength and weakness of these different components has been undertaken to employ it is strength and override its weakness. The system architecture is operationally used in developing different applications for the management of a university campus; a large potential is provided for operational tasks of facility management department, such as utilities infrastructure, as well as public community (student, staff) like routing application, searching for a person with defined criteria.","2010","2025-04-25 15:54:21","2025-04-25 15:54:21","","45-49","","","38-4","","","","International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences","","","","COPERNICUS GESELLSCHAFT MBH","BAHNHOFSALLE 1E, GOTTINGEN, 37081, GERMANY","English","","","","","","","Backup Publisher: Int Soc Photogrammetry & Remote Sensing ISSN: 2194-9034 Issue: W15 Type: Proceedings Paper","","","","Open Source; Information system; 3D GIS; BIM; CAD; Open Specification","","Kolbe, TH; Konig, G; Nagel, C","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This rise to prominence can be attributed to the high quality and suitability of the software. This quality and suitability is achieved through an elaborate peer-review process performed by a large community of users, who act as co-developers to identify and correct software defects and add features. Although this process is crucial to the success of free software projects, there is more to the free software development than the creation of a `bazaar'. In this paper we draw on existing free software projects to define a lifecycle model for free software. This paper then explores each phase of the lifecycle model and agrees that, while the bazaar phase attracts the most attention, it is the initial modular design that accommodates diverse interventions. Moreover, it is the period of transition from the initial group to the larger community based development that is crucial in determining whether a free software project will succeed or fail.","2004","2025-04-25 15:54:22","2025-04-25 15:54:22","","84-91","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Korea Informat Sci Soc; Korea Soc Engn Fdn; Samsung Elect; Samsung SDS; LG Elect; Korea IT Ind Promto Agcy; Elect & Telecommun Res Inst Type: Proceedings Paper","","","","free software; development process; software lifecycle","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. “simple”, intermediate” or “complex”, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.","2020-07-15","2025-04-25 15:54:22","2025-04-25 15:54:22","","","","","266","","","","","","","","","","English","","","","","","","Place: 24-28 OVAL RD, LONDON NW1 7DX, ENGLAND Publisher: ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD Type: Article","","","","Remote sensing; Cover estimation; Ecological monitoring; Guidos toolbox; Invasive alien species; Morphological spatial pattern analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.","2001-10","2025-04-25 15:54:22","2025-04-25 15:54:22","","277-304","","4","11","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","trust; control; McDonaldization; networked organization; rationalization; virtual organization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess “proof” of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and activities match those in their paid employment. Following a cohort of OSS programmers over a six-year period, we empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, our findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18% increase in wages. Moreover, we find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management. These findings suggest that rank within an OSS meritocracy is a credible and precise signal of participants' productive capacity and that participants' roles and activities in an OSS community have additional financial value when aligned with their paid employment.","2013-09","2025-04-25 15:54:22","2025-04-25 15:54:22","","520-538","","3","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software; signaling theory; job matching theory; labor economics; software industry","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V.

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.","2013-12","2025-04-25 15:54:22","2025-04-25 15:54:22","","361-370","","4","38","","","","","","","","","","English","","","","","","","Place: TWO COMMERCE SQ, 2001 MARKET ST, PHILADELPHIA, PA 19103 USA Publisher: LIPPINCOTT WILLIAMS & WILKINS Type: Article","","","","open source software; qualitative research; health information technology; hospital administration; vendors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.","2009-07-17","2025-04-25 15:54:22","2025-04-25 15:54:22","","","","","8","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Lymph node dissection can be challenging due to the inability to locate small metastatic lesions, and their proximity to at-risk organ(s). 3D volume rendered (3D-VR) patient specific images can help to address these challenges. We created patient-specific 3D-VR images using freely available open-source programs. Methods: This study included patients part of the clinical trial NCT04857502. Patients received a PET/CT prior to radioguided surgery. 3D Slicer was used to segment anatomy of interest (organs and tumor lesion(s)). After segmentation, the data was exported as an .OBJ file with an accompanying .MTL file. Manipulation of the .MTL file to restore model properties to the .OBJ file, were completed and both files were uploaded into Autodesk Viewer. Surgeons then received an email link to access the finished 3D-VR model on their smartphone or laptop for peri-operative preparation and/or guidance. Results: The method was used in a series of 14 patients with prostate cancer undergoing pelvic lymph node dissection with PSMA-radioguided robotic surgery using pre-operative PSMA PET/CT images acquired on average 103 +/- 69 days prior to resection. The creation of the 3D-VR models was successfully conducted in all 14 cases. In all cases, the lesions identified on the pre-operative PET/CT imaging 3D-VR models were successfully removed during surgery. Conclusion: We created patient-specific anatomical 3D-VR models that the surgeons can use for pre-surgical planning and intraoperative tumor localization, by applying free, open-source software that could be used in any procedure requiring careful and strategical planning.","2025-04","2025-04-25 15:54:22","2025-04-25 15:54:22","","10-16","","","236","","","","","","","","","","English","","","","","","","Place: 525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA Publisher: ACADEMIC PRESS INC ELSEVIER SCIENCE Type: Article","","","","3D imaging; 3D volume rendered models; Anatomical models; Pelvic lymph node dissection; PET/CT; PSMA; Radioguided surgery; Surgical planning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this experience report, which is an invited extension of a recently published work [1], we first analyze both functional and non-functional JIT requirements from three successful open source software (OSS) projects, including Firefox, Lucene, and Mylyn, to explore the common activities that shaped those requirements. We identify a novel refinement and resolution process that all studied requirements followed from their inception to complete realization and subsequent release. Noticing some interesting phenomena more specific to non-functional requirements (NFRs), we conduct a second study examining 50 NFRs from the aforementioned three subject systems. This study reveals a slightly different process followed in the refinement and resolution of NFRs. It also provides further evidence that NFR refinement and resolution activities focus more on implementation refinement rather than requirement elaboration in the studied systems. Our research provides new insights into how OSS project teams create quality features from simple initial descriptions of JIT requirements, uncovers activities more particular to JIT requirements engineering (RE) for NFRs, and opens new avenues for further research in the emerging JIT RE field.","2019-06","2025-04-25 15:54:22","2025-04-25 15:54:22","","24-33","","","14","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Functional requirements; Just-in-time requirements; Non-functional requirements; Refinement; Resolution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-25 15:54:22","2025-04-25 15:54:22","","2366-2380","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSAC; Huawei; Natl Sci Fdn; Technol Innovat Inst; Twenty Second Century Dora Technol; Ant Res; IBM; TikTok; Abelian; Input Outut Type: Proceedings Paper","","","","Patch backporting; Patch Semantics; Patch type","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we assume that the number of fault-detections observed on the bug tracking system tends to infinity, and discuss a method of statistical process control (SPC) for OSS projects by applying the logarithmic Poisson execution time model as a software reliability growth model (SRGM) based on a nonhomogeneous Poisson process (NHPP). Then, we propose a control chart method based on the logarithmic Poisson execution time model for judging the statical stability state, and estimating the additional development time for attaining the objective software failure intensity, i.e., the target value of the instantaneous fault-detection rate per unit time. We also discuss an optimal software release problem for determining the optimum time when to stop OSS development and to transfer it to user operation. Further, numerical illustrations for SPC are shown by applying the actual fault-count data observed on the bug tracking system.","2016-10","2025-04-25 15:54:22","2025-04-25 15:54:22","","","","5","23","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","Open source software (OSS); additional development time; control chart; logarithmic Poisson execution time model; software reliability growth model (SRGM); statistical process control (SPC)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We have developed a new generic software package for the solution of inverse problems implementing the Ensemble Smoother with Multiple Data Assimilation (genES-MDA). It is an open-source, platform-independent Python-based program. Its aim is to facilitate the management and configuration of the ES-MDA through several programming tools that help in the preparation of the different steps of ES-MDA. genES-MDA has a flexible workflow that can be easily adapted for the implementation of different variants of the ensemble Kalman filter and for the solution of generic inverse problems. This paper presents a description of the package and some application examples. genES-MDA has been tested in three synthetic case studies: the solution of the reverse flow routing for the estimation of the inflow hydrograph to a river reach using observed water levels and a calibrated forward model of the river system, the identification of a hydraulic conductivity field using piezometric observations and a known forward flow model, and the estimation of the release history of a contaminant spill in an aquifer from measured concentration data and a known flow and transport model. The results of all these tests have demonstrated the flexibility of genES-MDA and its capabilities to efficiently solve different types of inverse problems.","2022-10","2025-04-25 15:54:22","2025-04-25 15:54:22","","","","","167","","","","","","","","","","English","","","","","","","Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND Publisher: PERGAMON-ELSEVIER SCIENCE LTD Type: Article","","","","Python; Covariance localization and inflation; Stochastic inverse modeling; Uncertainty characterization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We show this framework by calculating spatial indicators-for 25 diverse cities in 19 countries-of urban design and transport features that support health and sustainability. We link these indicators to cities' policy contexts, and identify populations living above and below critical thresholds for physical activity through walking.

We do this considering that structure as a proxy for the conceptual architecture of the application. A metric is developed based on some current assumptions, and it is tested over a sample of Open Source projects. What is interesting to note, is that refactoring efforts are clearly visible when intended as reduction of complexity of source code.

Model predictive control (MPC) has been shown to be a successful control strategy generally and as well as for managing urban drainage specifically. This research describes and demonstrates the implementation of MPC for urban drainage systems using open source software (Python and The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM5). The system was demonstrated using a simplified use case in which an actively-controlled outlet of a detention pond is simulated. The control of the pond's outlet influences the flood risk of a downstream node. For each step in the SWMM5 model, a series of policies for controlling the outlet are evaluated. The best policy is then selected using an evolutionary algorithm. The policies are evaluated against an objective function that penalizes primarily flooding and secondarily deviation of the detention pond level from a target level. Freely available Python libraries provide the key functionality for the MPC workflow: step-by-step running of the SWMM5 simulation, evolutionary algorithm implementation, and leveraging parallel computing. For perspective, the MPC results were compared to results from a rule-based approach and a scenario with no active control. The MPC approach produced a control policy that largely eliminated flooding (unlike the scenario with no active control) and maintained the detention pond's water level closer to a target level (unlike the rule-based approach).","2019","2025-04-25 15:54:23","2025-04-25 15:54:23","","988-992","","","","","","","Green Energy and Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","ISSN: 1865-3529 Type: Proceedings Paper","","","","Active stormwater control; Flood prevention; Low-relief coastal cities; Model predictive control","","Mannina, G","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.","2016","2025-04-25 15:54:23","2025-04-25 15:54:23","","37-44","","","","","","","Proceedings of the European Conference on Knowledge Management","","","","ACAD CONFERENCES LTD","CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND","English","","","","","","","ISSN: 2048-8963 Type: Proceedings Paper","","","","knowledge sharing; communities of practice; clusters; free software communities; sharing profiles","","Moffett, S; Galbraith, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

India is the largest consumer of water, with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11-01","2025-04-25 15:54:23","2025-04-25 15:54:23","","597-625","","4","42","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","open source; free software; reputational capital; copyleft; immaterial labour; new spirit of capitalism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computed tomography (CT) is commonly used to overcome projection errors in two-dimensional angular measurements of dog hindlimb alignment. Three-dimensional volume rendering (VR) techniques permit virtual positioning and variable projection, but the final CT-image that defines the projection plane for angular measurements remains two-dimensional.Objective We wanted to develop a true three-dimensional open-source technique to measure the alignments of the hind limbs of dogs in CT scanners.Methods We developed an open-source 3D Slicer plug-in, to perform angular measurements using vector calculations in three-dimensional space. In 113 CT-scans of canine pelvic limbs, femoral torsion, femoral varus, femorotibial rotation, tibial torsion, tibial varus and tibiotalar rotation angles were calculated and compared to an already validated technique using VoXim (R).Results Reference points were identified and measurements were possible in the 113 acquisitions. The greatest difference between the two techniques was 1.4 degrees at only one tibial torsion angle. Mean values for all Bland-Altman plots did not show significant differences and were less than 0.07 degrees for all comparisons.Discussion Based on these results we considered angular measurements of canine hind limb alignment in CT scans using the 3D Slicer extension program sufficiently accurate for clinical orthopedic and surgical purposes in veterinary medicine.Conclusion With our open-source 3D Slicer extension software, we provide a free accessible tool for veterinary orthopedic surgeons and thus we hope to improve angular measurements in CT-scans of canine hind limb deformities through true three-dimensionality.","2024-03-29","2025-04-25 15:54:23","2025-04-25 15:54:23","","","","3","19","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-25 15:54:23","2025-04-25 15:54:23","","361-390","","1","47","","","","","","","","","","English","","","","","","","Place: UNIV MINNESOTA-SCH MANAGEMENT 271 19TH AVE SOUTH, MINNEAPOLIS, MN 55455 USA Publisher: SOC INFORM MANAGE-MIS RES CENT Type: Article","","","","pandemic; unemployment; open source software; Open source software community; digital resilience; exogenous shock; IT knowledge workers; IT professionals","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: Ten STL dental and maxillofacial models were obtained from various imaging technologies, including intraoral scanners, computer-aided design (CAD) software, and cone-beam computed tomography (CBCT), and saved as STL files. ChatGPT was used to generate Python scripts in Blender for mesh simplification and data compression, which were then saved as .py files. The models were regenerated from these scripts in Blender, and their accuracy was assessed using GOM Inspect software, comparing trueness and precision. Statistical analysis, including Kruskal-Wallis and Mann-Whitney tests, was conducted to evaluate differences in file sizes between the original, Python-generated, and regenerated STL files, with statistical analyses performed at a level of significance alpha=0.05. Results: The scripting-based technique was successfully utilized in ChatGPT to generate Python script code for accessing comprehensive data on STL models, utilizing Blender's scripting functionality. This approach enabled the generation, regeneration, and visualization of STL models, resulting in significantly smaller file sizes for both the Python script and regenerated STL files compared to the original STL files (p < 0.001). No significant differences in trueness were observed, with deviations ranging from 0.0 m to 6.8 mu m, and all regenerated STL models demonstrated perfect precision. Additionally, a proportional relationship was noted between the original STL file sizes and processing times. Conclusions: The scripting-based approach proved to be effective in coding, storing, and regenerating STL dental data with reduced file sizes and efficient processing times without compromising the accuracy. Clinical Significance: Various STL dental models of patients can be coded, stored, and regenerated to be used again within efficient processing time without affecting the accuracy.","2025-05","2025-04-25 15:54:24","2025-04-25 15:54:24","","","","","156","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Dentistry; Open-source software; 3d data management; accuracy; Blender scripting; Stl file optimization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 15:54:24","2025-04-25 15:54:24","","484-510","","","46","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","OSS; Decision Making; Decision Process; F/LOSS; Free/Libre Open Source Software Development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.","2018-05","2025-04-25 15:54:24","2025-04-25 15:54:24","","","","5","10","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","QGIS; remote sensing; global warming; land surface temperature; Landsat-8; semi-automatic classification plugin; urban heat island; urbanization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computational intelligence (CI) in general and particle swarm optimization (PSO) algorithms in particular have been shown to accelerate finding optimal printing parameters. Unfortunately, the implementation of CI has been prohibitively complex for noncomputer scientists. To overcome these limitations, this article develops, tests, and validates PSO Experimenter, an easy-to-use open-source platform based around the PSO algorithm and applies it to optimizing recycled materials. Specifically, PSO Experimenter is used to find optimal printing parameters for a relatively unexplored potential distributed recycling and additive manufacturing (DRAM) material that is widely available: low-density polyethylene (LDPE). LDPE has been used to make filament, but in this study for the first time it was used in the open source fused particle fabrication/fused granular fabrication system. PSO Experimenter successfully identified functional printing parameters for this challenging-to-print waste plastic. The results indicate that PSO Experimenter can provide 97% reduction in research time for 3D printing parameter optimization. It is concluded that the PSO Experimenter is a user-friendly and effective free software for finding ideal parameters for the burgeoning challenge of DRAM as well as a wide range of other fields and processes.","2023-12-01","2025-04-25 15:54:24","2025-04-25 15:54:24","","1287-1300","","6","10","","","","","","","","","","English","","","","","","","Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC Type: Article","","","","fused particle fabrication; LDPE; particle swarm optimization; recycling; waste plastic","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We started the study by introducing the population pyramid visualization to software development communities, called software population pyramids, and found a typical pattern in shapes. This pattern comes from the differences in attracting coding contributors and discussion contributors. To understand the causes of the differences, we then build game-theoretical models of the contribution situation. Based on these results, we again analyzed the projects empirically to support the outcome of the models, and found empirical evidence. The answers to the initial questions are clear. To incentivize developers to code, the projects should prepare documents, or the projects or third parties should hire developers, and these are what sustainable projects in GitHub did in reality. In addition, making innovations to reduce the writing costs can also have an impact in attracting coding contributors.","2015","2025-04-25 15:54:24","2025-04-25 15:54:24","","15-21","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE COMP SOC; TCSE; ACM; SIGSOFT Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work also provides guidelines to implement an automatic tool that derives the implementation of routing deadlock-free policies within the connector from the dynamic behavior specification of the COM components. Deadlock is then prevented by inserting the synthesized connector within the system via COM composition mechanisms while letting the system COM servers unmodified.

Most studies, based on a popular FLOSS repository (SourceForge). have concluded that the vast majority of projects are failures. This Study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities ire formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success. (C) 2008 Elsevier Inc.

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways. This may be due primarily to the fact that open source ultimately produces greater value on both the use and production sides, implying an impact on welfare. This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market. To support this, a market concentration index, the HHI index, is tested over the case of web servers. As a result the study reveals that under the appropriate conditions, OSS call have a positive impact on welfare.","2008","2025-04-25 15:54:25","2025-04-25 15:54:25","","1-26","","","","","","","Social Issues Justice and Status","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Stroud, BH; Corbin, SE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose RecGFI, an effective practical approach for the recommendation of good first issues to newcomers, which can be used to relieve maintainers' burden and help newcomers onboard. RecGFI models an issue with features from multiple dimensions (content, background, and dynamics) and uses an XGBoost classifier to generate its probability of being a GFI. To evaluate RecGFI, we collect 53,510 resolved issues among 100 GitHub projects and carefully restore their historical states to build ground truth datasets. Our evaluation shows that RecGFI can achieve up to 0.853 AUC in the ground truth dataset and outperforms alternative models. Our interpretable analysis of the trained model further reveals interesting observations about GFI characteristics. Finally, we report latest issues (without GFI-signaling labels but recommended as GFI by our approach) to project maintainers among which 16 are confirmed as real GFIs and five have been resolved by a newcomer.","2022","2025-04-25 15:54:25","2025-04-25 15:54:25","","1830-1842","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; Assoc Comp Machinery, Special Interest Grp Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","open-source software; onboarding; good first issues","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key factor for the success of a free software project is its development dynamics, dependent on the attraction and retention of users and developers. The license plays an important role in this scenario, because by imposing restrictions on the use of the source code it attracts potential contributors in a different way.

To keep this foundation intact, the open source community needs to actively invest in sustainable approaches to bring in new contributors and nurture existing ones. We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a “rising contributor” badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.","2022","2025-04-25 15:54:25","2025-04-25 15:54:25","","36-40","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery Type: Proceedings Paper","","","","open source; maintainers; social good","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this case report was to demonstrate the retreatment of a female patient, dissatisfied with the instability of the compensatory orthodontic treatment, chin deviation, and forward inclination of the maxillary incisors, which was successfully treated with Minimal Presurgical Orthodontic approach associated with customized lingual brackets and virtual planning on the open-source Blender 3D software, where the post-surgical maxillary lingual brackets were also designed. Orthodontic preparation was performed in 5 months. After surgery, orthodontic treatment was finished with the aid of mini-implants and miniplates. The total treatment time was 18 months. Great facial and occlusal results were obtained and the patient was satisfied. Overall, all treatment steps were performed following a digital workflow and open-source software. It is possible to conclude that Minimal Presurgical Orthodontic Preparation was an excellent alternative for the retreatment of this patient with mandibular asymmetry and increased treatment expectations. Additionally, the surgical planning and design of lingual braces with open-source software can be considered useful and low-cost alternatives for orthodontists.","2023-03","2025-04-25 15:54:25","2025-04-25 15:54:25","","","","1","21","","","","","","","","","","English","","","","","","","Place: 62, RUE CAMILLE DESMOULINS, ISSY LES MOULINEAUX CEDEX, 92442, FRANCE Publisher: ELSEVIER MASSON SAS EDITEUR Type: Article","","","","Software; Adult treatment; Case report; Class III orthognathic; Facial asymmetry; Imaging; Lingual appliance; Orthodontics; surgery; Three-dimensional","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors' engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors' attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023-05-01","2025-04-25 15:54:25","2025-04-25 15:54:25","","3106-3130","","5","49","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","Organizations; Task analysis; Mentoring; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; taxonomy; mentoring process; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The success of open source software is known to be attributable to a massive number of contributors engaging in the development process. However, an efficient open source software project is not guaranteed simply by active participation by many; a coordination mechanism is needed to seamlessly manage the multi-party collaboration. On this basis, this study aimed to examine the internal regulatory processes based on Git and GitHub, which serve as such a mechanism, and redefine the efficiency of open source software projects to fully reflect them. For this purpose, a two-stage data envelopment analysis was used to measure the project efficiency reflecting the internal processes. Moreover, this study considered the Kruskal-Wallis test and Tobit regression analysis to examine the effects of the participation by many on an open source software project based on the newly defined efficiency.

The proposed system utilises the community formed around F/OSS projects to produce meaningful recommendations based on specific user preferences. We suggest that such an approach would overcome some of the difficulties complicating user choice by making useful suggestions and can fit seamlessly within the structure of the majority of F/OSS projects.

It has been reported that less than 10% of Open Source Software (OSS) contributors in GitHub are women. Although related qualitative and quantitative studies point out the gender gap, the technical and social interaction of females within OSS still remain unexplored and largely misunderstood. As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions. Thus, we propose to answer the questions: where are females in OSS projects? How they evolve? and How they contribute to the sustainability of the OSS social capital?. We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity. We found that females are extremely underrepresented within OSS communities, but when they participate they are productive just as males, they evolve following relatively the same patterns than males and remain more involved in projects than males.","2019","2025-04-25 15:54:26","2025-04-25 15:54:26","","308-319","","","","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","Backup Publisher: IFIP WG 5 5 COVE Co Operat infrastructure Virtual Enterprises & Elect Business; Soc Collaborat Networks; Politecnico Torino; Nova Univ Lisbon; UNINOVA; Univ Amsterdam ISSN: 1868-4238 Type: Proceedings Paper","","","","Open Source Software; Social Network Analysis; Diversity; Gender; Socio-Technical interactions","","CamarinhaMatos, LM; Afsarmanesh, H; Antonelli, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While previous research recognizes the significance of trust in an organizational setting, there is a lack of understanding in how trust is exhibited in OSS distributed teams, where there is an absence of direct, in-person communications. To foster trust and collaboration in OSS teams, we need to understand what trust is and how it is exhibited in written developer communications (e.g., pull requests, chats). In this paper, we first investigate various dimensions of trust to identify the ways trusting behavior can be observed in OSS. Next, we sample a set of 100 GitHub pull requests from Apache Software Foundation (ASF) projects, to analyze and demonstrate how each dimension of trust can be exhibited.

Data from semi-structured interviews reveal that company motivations can be categorized into four levels (Founders' Vision, Reputation, Business Advantage, and Reciprocity) and companies participate through different mechanisms (e.g., Developers' Time, Mentoring Time, Advocacy & Promotion Time), each of which tie to the different types of motivations.

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals' early career stages profoundly impact their long-term career success. However, newcomers' early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers' dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers' contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers' early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers' technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers' early careers and hence shed light on future research in this direction.","2023-02-01","2025-04-25 15:54:26","2025-04-25 15:54:26","","529-548","","2","49","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","open source; Task analysis; Ecosystems; Documentation; Engineering profession; Codes; Correlation; Focusing; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These projects often provide onboarding guidelines in their `CONTRIBUTING' files (e.g., CONTRIBUTING.md on GitHub). These files explain, for example, how to find open tasks, implement solutions, and submit code for review. However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions' adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file. Our approach may help community builders identify missing information in the project ecosystem they maintain and newcomers can understand what to expect in CONTRIBUTING files.","2023","2025-04-25 15:54:26","2025-04-25 15:54:26","","16-28","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei Type: Proceedings Paper","","","","open source; software engineering; FLOSS; novices; onboarding","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We thus suggest that partner recommendation across different roles may benefit both the users and developers, i.e., once we are able to make successful recommendation for those in need, it may dramatically contribute to the productivity of developers and the enthusiasm of users, thus further boosting OSS projects' development. Motivated by this potential, we model the partner recommendation as link prediction task from email data via network embedding methods. In this article, we introduce time-series snapshot network (TSSN) that is a mixture network to model the interactions among users and developers. Based on the established TSSN, we perform temporal biased walk (TBW) to automatically capture both temporal and structural information of the email network, i.e., the behavioral similarity between individuals in the OSS email network. Experiments on ten Apache data sets demonstrate that the proposed TBW significantly outperforms a number of advanced random walk-based embedding methods, leading to the state-of-the-art recommendation performance.","2022-08","2025-04-25 15:54:27","2025-04-25 15:54:27","","1048-1059","","4","9","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","social network; Productivity; Task analysis; Sustainable development; Social networking (online); Data models; Synchronization; open-source software (OSS); Link prediction; network embedding; partner recommendation; random walk; Search problems; temporal network","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, according to the software version sequence, we construct the corresponding developer collaboration network of the Angular OSS community and then analyse this network's structural stability during network evolution. The results show that the network always presents an economical modular small-world structure during its evolution. The maintenance of the structure is related to a cohesive core, which is composed of two types of nodes (i.e., hubs and connectors). The hubs organize noncore nodes to form modules, while connectors facilitate the formation of inter-module connections. The overall results highlight the important role of core developers in the sustainable development of OSS communities and may provide a reference for community initiators to implement protection strategies for core developers.","2022-07-08","2025-04-25 15:54:27","2025-04-25 15:54:27","","","","7","17","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The literature shows that the FOSS approach has attracted a great deal of interest, in particular when implemented with projects that have humanitarian goals (HFOSS).

Each model is described in terms of its characteristics and how it fits the needs of the institution using the model. Assessment of each model is also presented. We then discuss the themes that are common across the models, such as project selection, team formation, mentoring, and student assessment. We examine the choices made by each model, as well as the challenges faced.

In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.","2025-03","2025-04-25 15:54:27","2025-04-25 15:54:27","","","","1","33","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Open source software; GitHub; Software quality; Operations research; Development process; Multi-criteria decision analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of vendors. In other words, management of co-creation and competition are being conducted at the same time.

The copyright regime is so restrictive that it turns a normal learning process into a series of potential copyright violations. The Free Software Movement (FSM) represents a substantial community effort to counter this trend. It seeks to supersede the copyright regime by offering the `Copyleft' licensing mode, which facilitates the formation of a cooperative, resource- sharing community. The FSM has been so successful that it has challenged the utilitarian values presumed in copyright law, has fuelled widespread reassessment of copyright law, and has influenced many who engage in various creative activities. Claiming to bear similar values, Creative Commons (CC) provides licensing models for people to waive some rights granted to them. However, CC differs from the FSM in significant ways. Most notably, the flexible CC licensing model weakens the firm philosophical and political ground which binds FSM advocates together. Hence, although CC's rapid growth seems to signal its success, it is questionable whether such success is as enduring as the FSM's, or if it is leading to a different result. While CC champions the author's freedom to decide how to use his or her bundle of property rights granted by copyright law, the FSM advocates the freedom to build and live in an alternative, vital and self- sustaining community. The existence of such an alternative model not only allows these particular participants to be independent from the proprietary world, but also may empower the rest of society to imagine different kinds of relationships between human beings and their creative activities.","2006-12","2025-04-25 15:54:28","2025-04-25 15:54:28","","337-347","","4, SI","4","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We model the individual's chances to become a valuable contributor through her capacity, willingness, and the opportunity to contribute at the time of joining. Using issue tracking data of Mozilla and Gnome, we find that the probability for a new joiner to become a Long Term Contributor (LTC) is associated with her willingness and environment. Specifically, during their first month, future LTCs tend to be more active and show more community-oriented attitude than other joiners. Joiners who start by commenting on instead of reporting an issue or ones who succeed to get at least one reported issue to be fixed, more than double their odds of becoming an LTC. The micro-climate with a productive and clustered peer group increases the odds. On the contrary, the macro-climate with high project popularity and the micro-climate with low attention from peers reduce the odds. This implies that the interaction between individual's attitude and project's climate are associated with the odds that an individual would become a valuable contributor or disengage from the project. Our findings may provide a basis for empirical approaches to design a better community architecture and to improve the experience of contributors.","2012","2025-04-25 15:54:28","2025-04-25 15:54:28","","518-528","","","","","","","International Conference on Software Engineering","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: ACM Special Interest Grp Software Engn (SIGSOFT); IEEE Comp Soc Tech Council Software Engn (TCSE); Special Interest Grp Software Engn Swiss Informat Soc (SI-SE); Univ Zurich, Dept Informat; ACM; IEEE Comp Soc ISSN: 0270-5257 Type: Proceedings Paper","","","","open source; interaction of person and environment; Long Term Contributor; opportunity; willingness","","Glinz, M; Murphy, G; Pezze, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Modeling Participant's Initial Behavior","IEEE TRANSACTIONS ON SOFTWARE ENGINEERING","","0098-5589","10.1109/TSE.2014.2349496","","Motivation: To survive and succeed, FLOSS projects need contributors able to accomplish critical project tasks. However, such tasks require extensive project experience of long term contributors (LTCs). Aim: We measure, understand, and predict how the newcomers' involvement and environment in the issue tracking system (ITS) affect their odds of becoming an LTC. Method: ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. We also reproduced the results on new data provided by Mozilla. Results: We constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants. Newcomers who are able to get at least one issue reported in the first month to be fixed, doubled their odds of becoming an LTC. The macro-climate with high project popularity and the micro-climate with low attention from peers reduced the odds. The precision of LTC prediction was 38 times higher than for a random predictor. We were able to reproduce the results with new Mozilla data without losing the significance or predictive power of the previously published model. We encountered unexpected changes in some attributes and suggest ways to make analysis of ITS data more reproducible. Conclusions: The findings suggest the importance of initial behaviors and experiences of new participants and outline empirically-based approaches to help the communities with the recruitment of contributors for long-term participation and to help the participants contribute more effectively.

However, the stages when developers leave the projects are still weakly explored and are not well-defined in existing developers' lifecycle models. In this position paper, we enrich the knowledge about the leaving stage by identifying sleeping and dead states, representing temporary and permanent brakes that developers take from contributing. We conducted a preliminary set of semi-structured interviews with active developers. We analyzed the answers by focusing on defining and understanding the reasons for the transitions to/from sleeping and dead states.

ESE (endoscopic submucosal excavation) is widely used for the treatment of digestive diseases. The dental floss traction (DFT) method has been successfully used to facilitate ESE to resect mucosal lesions such as early gastric cancer. DFT has not been used in ESE to remove submucosal masses. This study aimed to examine the efficacy of DFT-assisted ESE (DFT- ESE) for the removal of submucous masses. Methods. From March 2017 to May 2017, a total of 12 patients with gastric submucosal masses at the First Affiliated Hospital of Nanchang University, Jiangxi, China, were enrolled. The tumor characteristics, en bloc resection rates, complications, and outcomes on follow-up were evaluated for all patients. Results. The 12 submucosal tumors were completely removed by DFT- ESE. Nine were gastrointestinal stromal tumors. Two were Schwannoma, located in the greater curvature of the gastric corpus. One was gastric ectopic pancreas. All the resected tumors were removed completely with intact tumor capsules. There was no more bleeding or perforation after the endoscopic closure of the perforation or the wound after the DFT-ESE, and no recurrences were identified at the time of follow-up. Conclusions.

Once software complexity is one of the most important attributes to determine software maintainability, controlling its level in the system evolution process makes the software easier to maintain, reducing the maintainability costs. Otherwise, uncontrolled complexity makes the maintenance and enhancement process lengthy, more costly and some times it can contribute to the system abandonment.

However, it has been criticized that FLOSS development is often considered as a homogeneous phenomenon grounded by assumptions rather than empirical evidence. Proper empirical methods that can shed light into FLOSS development are desirable. In this paper, we propose an empirical method to validate a software development model for FLOSS, the Adapted Staged Model for FLOSS. We mined some selected metrics from Apache Ivy and study their evolution using S-shaped curves. Our results indicate that S-shaped curves can model software evolution well for Ivy. Moreover, we demonstrated that our method can be used to identify successfully different stages of its development, validating part of the Adapted Staged Model for FLOSS.","2013","2025-04-25 15:54:28","2025-04-25 15:54:28","","468-471","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Software Improvement Grp; Lab Qual Software ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system's sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries. Specifically, we leveraged a weighted combination of semantics, lexical, and shallow features in conjunction with the Random Forest ensemble learning method. Finally, we discuss the practical applicability of our classifier for mapping and visualizing quality-related concerns into the codebase with an example from the Derby project. To summarize, this work represents an effort and an early awareness to improve the underlying management of issue tracking systems and stakeholder requirements in open-source communities.","2021","2025-04-25 15:54:28","2025-04-25 15:54:28","","12-23","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process. In detail, we analyze what review feedbacks encourage a contributor to continue with OSS project.

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 15:54:29","2025-04-25 15:54:29","","477-512","","4","34","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Open source software; Enterprise resource planning; Case study; IT adoption; IT risk management; SME","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although industrial applications traditionally rely on PLC-based hardware and, in any case, proprietary software, i.e. operating systems and development tools, in recent years dramatic improvements in hardware computer power and free software quality made realistic the employment of architectures based on PC-compatible hardware and GNU/Linux software, more common in the research community. The advantages of a free infrastructure, that can become the terrain of fruitful cooperation between research institutions and companies, can be exploited mainly in fields, in which the added value is in the application, i.e. in mechanical and algorithmic solutions, and where the point of view is that of aware users of an infrastructure, rather than of R&D competitors. This is the case of the project presented in the following, representing a success story in which the discussion between a research group and a small enterprise led to the identification of the requirements and the joined development of a common software infrastructure. When the project started in 2004, both partners, i.e. the Autonomous robotic systems and control group of CNR-ISSIA and Green Project Srl, had to substitute the obsolete platforms of their marine robots and marking machines for casting products in steelworks with a stable software and hardware infrastructure able of transparently integrating technological improvements while remaining compatible with the past (backward compatibility). On the basis of considerations, discussed below, about system reliability, development and maintenance costs (including human resources), foreseen compatibility and general technical soundness, the choice was to verify the possibility of using standard GNU/Linux for embedded real-time applications. The result is the main technical contribution of this chapter, i.e. the practical demonstration of the possibility of using standard GNU/Linux for implementing embedded real-time control systems working up to a sampling frequency of at most 2 Khz. Furthermore, four years later, the developed system is still demonstrating its capabilities transparently integrating technological improvements and increasing more and more its performance thanks to the new real-time properties of the Linux kernel. A first operative release of the platform was completed in 2005 and integrated with the CNR-ISSIA Charlie unmanned surface vehicle (USV) for robotics research. A second application was the porting to the platform of the software of the control system of Hammer, a steelwork industrial machine used for marking continuous casting products, developed by Greenproject s.r.l. At the moment, the platform is supporting the development of the ALANIS (Aluminium Autonomous Navigator for Intelligent Sampling) USV1 for surface and underwater coastal monitoring. Moreover, the integration with generic field buses and image acquisition systems is being carried out.

The objective of this research is to empirically examine the Brooks' Law in a Free Software context. The principle is separated out into its two primary premises: the first is based on a developer's ability to become productive when joining a new team; the second premise relates to the quality of coordination as the team grows. Three large projects are studied for this purpose: KDE, Plone and Evince. Based on empirical evidence, the paper provides two main contributions: based on the first premise of Brooks' Law, it claims that coordination costs increase only in a very specific phase for Free Software projects. After that, these costs become quasi-constant. Secondly, it shows that a ramp up period exists in Free Software projects, and this period marks the divide between projects that are successful at engaging new contributors from others that only benefit from occasional new contributors.","2009","2025-04-25 15:54:29","2025-04-25 15:54:29","","319-328","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Education studies have also analysed the importance of these communities in spreading and sharing knowledge and educational culture has looked to these organizational forms for inspiration. At the same time, the link between these experiences and the development of pedagogical models emerging from cognitive sciences, systemic theory and the new forms of constructivism, which have generated a fruitful theory/practice circle, has been reinforced. The aim of this paper is to analyse the particular type of organizational, communicative and productive context of Open Communities: Free Software Communities, to understand how they work, their efficacy and to show their close link with dynamics and relations of an educational, formative and didactic type. Learning communities can still learn strategies of communication, organization and socialization from these communities, as well as the value of motivation and the importance of freedom and circulation of knowledge in order to build up efficient communities. We can also gain the understanding that the success of these communities depends on the fact that they are educational communities, therefore education studies can convey values, models and a culture of sharing to other sectors as well, such as the one taken into consideration: Free Software Communities.

It is a clonal B-cell disorder characterized by the proliferation of malignant plasma cells in the bone marrow, the presence of monoclonal serum immunoglobulin, and osteolytic lesions. An increasing amount of evidence shows that the interactions of MM cells and the bone microenvironment play a significant role, suggesting that these interactions may be good targets for therapy. The osteopontin-derived collagen-binding motif-bearing peptide NIPEP-OSS stimulates biomineralization and enhances bone remodeling dynamics. Due to its unique targeted osteogenic activity with a broad safety margin, we evaluated the potential of NIPEP-OSS for anti-myeloma activity using MM bone disease (MMBD) animal models. In a 5TGM1-engrafted NSG model, the survival rates of the control and treated groups were significantly different (p = 0.0014), with median survival times of 45 and 57 days, respectively. The bioluminescence analyses showed that myeloma slowly developed in the treated mice compared to the control mice in both models. NIPEP-OSS enhanced bone formation by increasing biomineralization in the bone. We also tested NIPEP-OSS in a well-established 5TGM1-engrafted C57BL/KaLwRij model. Similar to the previous model, the median survival times of the control and treated groups were significantly different (p = 0.0057), with 46 and 63 days, respectively. In comparison with the control, an increase in p1NP was found in the treated mice. We concluded that NIPEP-OSS delays mouse myeloma progression via bone formation in MMBD mouse models.","2023-04-26","2025-04-25 15:54:29","2025-04-25 15:54:29","","","","9","15","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","bone anabolic agent; bone mineralization; multiple myeloma; multiple myeloma bone disease; NIPEP-OSS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The result is a theory that small businesses founded by free/libre software advocates have three characteristics of social entrepreneurships. First, social benefit is prioritized over wealth creation. Second, the business's social mission is not incidental but is furthered through its for-pro fit activities, rather than supported by the company's profits.

During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS. These results suggest that an inter-family succession of Betaproteobacteria occurred in response to colonization by mosses, followed by plants.","2019-09-25","2025-04-25 15:54:29","2025-04-25 15:54:29","","268-277","","3","34","","","","","","","","","","English","","","","","","","Place: C/O DR.

Here, we provide an open travel time matrix dataset that describes travel times between the centroids of all cells in a grid (N = 13,132) covering the metropolitan area of Helsinki, Finland. The travel times recorded in the dataset follow a door-to-door approach that provides comparable travel times for walking, cycling, public transport and car journeys, including all legs of each trip by each mode, such as the walk to a bus stop, or the search for a parking spot. We used the r5py Python package, that we developed specifically for this computation. The data are sensitive to diurnal variations and to variations between people (e.g. slow and fast walking speed). We validated the data against the Google Directions API and present use cases from a planning practice. The five key principles that guided the data set design and production - comparability, simplicity, reproducibility, transferability, and sensitivity to temporal and interpersonal variations - ensure that urban and transport planners, business and researchers alike can use the data in a wide range of applications.","2024-08-09","2025-04-25 15:54:29","2025-04-25 15:54:29","","","","1","11","","","","","","","","","","English","","","","","","","Place: HEIDELBERGER PLATZ 3, BERLIN, 14197, GERMANY Publisher: NATURE PORTFOLIO Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there are several limitations of existing studies that limit the wide adaptation of open-source projects in a classroom setting, including (1) the selected project is limited to one particular project, (2) most studies only investigated on its effect on teaching a specific SE concept, and (3) students may make mistakes in their contribution which leads to poor quality code. Meanwhile, software companies have successfully launched programs like Google Summer of Code (GSoC) and FindBugs “fixit” to contribute to open-source projects. Inspired by the success of these programs, we propose GitHub-OSS Fixit, a team-based course project where students are taught to contribute to open-source Java projects by fixing bugs reported in GitHub. We described our course outline to teach students SE concepts by encouraging the usages of several automated program analysis tools. We also included the carefully designed instructions that we gave to students for participating in GitHub-OSS Fixit. As all lectures and labs are conducted online, we think that our course design could help in guiding future online SE courses. Overall, our survey results show that students think that GitHub-OSS Fixit could help them to improve many skills and apply the knowledge taught in class. In total, 154 students have submitted 214 pull requests to 24 different Java projects, in which 93 of them have been merged, and 46 have been closed by developers.","2021","2025-04-25 15:54:29","2025-04-25 15:54:29","","1-10","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT Type: Proceedings Paper","","","","software engineering; Open-source software; program repair","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, our objective was to advance the practicality of drug-coated floss as an intra gum pocket drug delivery system. The initial design of this delivery system has been previously reported by us. Here, we advance the concept further through in vitro and in vivo evaluation. A floss piece was dip coated in the middle section with model molecules leaving free ends for holding. Porcine gum tissues were used ex vivo and in vivo to evaluate the coated floss, including effect of coating thickness on delivery efficiency, ability to deliver more than one type of molecule (one hydrophilic and one hydrophobic), mechanical properties using a scratch test, and finally retention of delivered material in vivo in the porcine model. After reaching a certain coating thickness, the delivery efficiency of the coated floss decreased, indicating the presence of an optimal coating thickness. Hydrophobic and hydrophilic molecules were successfully coated and delivered with high efficiency into gum pockets. The scratch test indicated that the coatings were resilient. Lastly, the in vivo analysis showed that the drug coating was delivered into the porcine gum pocket with about 65% efficiency, and the coatings could maintain extended residency within the gum pocket despite the native adverse environment of the oral cavity. Overall, this data shows that drug-coated floss can act as a drug delivery vehicle and has potential to provide a minimally invasive and practical method for the delivery of drugs into the gum pockets.","2022-06-29","2025-04-25 15:54:29","2025-04-25 15:54:29","","28663-28670","","25","14","","","","","","","","","","English","","","","","","","Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC Type: Article","","","","floss; coated; drug; gingivitis; gum; mouth; oral cavity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose a method of software reliability assessment based on a flexible hazard rate model considering the influence of installer application such as App Store of iOS and Android Market of Android OS. Also, we derive several reliability assessment measures. In particular, we show several numerical examples of reliability assessment for our hazard rate model. Then, we show that the proposed model can assist quality improvement for embedded OSS systems development.

These projects carrying out research on MANETs have successfully implemented adhoc networking on few targeted devices, hence implementation of Mobile Adhoc Network (MANET) on every new Android based device is quite challenging in nature. We have researched on Commercial Off the Shelf (COTS) devices (such mobile phones and tablets) to implement adhoc networking using open source software (OSS) such as Serval Mesh, MANET Manager, WiFi Tether applications. We have also modified the TrevE-Mod WiFi Tether application to work successfully with MANET Manager and Linux/ Windows based Personal Computers (PCs) in an adhoc network. The results achieved by performance evaluation tools and testing of VoIP applications have proved it to be satisfactory. We have also satisfactorily implemented, configured and tested point to point Virtual Private Network (VPN) between MANET nodes using OSS (VPN Server, OpenVPN for Android, OpenVPN Connect). The application of standards based security algorithms (for authentication and encryption in VPNs) demonstrates that these technologies can be effectively used for secure collaboration in adhoc environments as well.","2016","2025-04-25 15:54:30","2025-04-25 15:54:30","","485-492","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Honeywell Int Inc; Knowledge Based Syst Inc; Ball Aerosp & Technologies Corp; Intel Corp; Microsoft Res; Springer Verlag Type: Proceedings Paper","","","","OSS; VPN; COTS; adhoc network; MANET; tethering","","Smari, WW","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To determine the ideal time to apply an implant after augmentation with Bio-Oss Collagen and to observe if there are differences in the age of the patients and the sex, the aim of this randomized controlled clinical trial was to compare the post-extraction changes in angiogenic and osteogenic aspects during spontaneous bone regeneration with those during socket preservation using Bio-Oss Collagen. Sixty-six patients were included in this study. After 8-12 weeks, bone biopsies were embedded in paraffin and histological and immune-histological investigated. Using qRT-PCR bone (Alpl, Bglap, Runx2) and angiogenic markers (VEGF, caveolin-1) were identified. The histomorphometric analysis of all examined samples showed no differences between treated and untreated sockets, but a tissue compression. After classification in bone regeneration stages, more samples with woven bone were present in treated sockets than in controls. The Alpl expression correlates with increase in mature bone tissue. In treated sockets a significant decrease in CD34 and caveolin-1 protein expression was found. Additionally, a significant increase of Runx2 and VEGF mRNA was detected in patients younger than 50 years. Thus, all specimens showed ossification in different stages after eight weeks of healing. The treated group gives an earlier stage of ossification than controls, but produces densified tissue with greater volume fraction. It can be assumed that successful implant placement in Bio-Oss Collagen augmented extraction sockets is possible after eight weeks of bone healing. (C) 2021 Elsevier B.V.

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.","2014","2025-04-25 15:54:30","2025-04-25 15:54:30","","401-412","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery Special Interest Grp Software Engn; CVIC SE; NSF; Microsoft Res; Huawei; Neusoft; Siemens; Yonyou; Hong Kong Univ Sci & Technol; Google; Radica; Samsung Res Amer; IBM Res; TCL; CCC Type: Proceedings Paper","","","","sequence analysis; layered network; Markov entropy; structural complexity; Time-series","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of minimization reduces differences that might arise by chance between the study arms in the distribution of patient characteristics such as gender, ethnicity and age. However, unlike randomization, minimization requires real time assessment of each new participant with respect to the preceding distribution of relevant participant characteristics within the different arms of the study. For multi-site studies, this necessitates centralized computational analysis that is shared between all study locations. Unfortunately, there is no suitable freely available open source or free software that can be used for this purpose. OxMaR was developed to enable researchers in any location to use minimization for patient allocation and to access the minimization algorithm using any device that can connect to the internet such as a desktop computer, tablet or mobile phone. The software is complete in itself and requires no special packages or libraries to be installed. It is simple to set up and run over the internet using online facilities which are very low cost or even free to the user. Importantly, it provides real time information on allocation to the study lead or administrator and generates real time distributed backups with each allocation. OxMaR can readily be modified and customised and can also be used for standard randomization. It has been extensively tested and has been used successfully in a low budget multi-centre study. Hitherto, the logistical difficulties involved in minimization have precluded its use in many small studies and this software should allow more widespread use of minimization which should lead to studies with better matched control and experimental arms. OxMaR should be particularly valuable in low resource settings.","2014-10-29","2025-04-25 15:54:30","2025-04-25 15:54:30","","","","10","9","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whether a project participant is initiated as a developer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e. g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving developer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e. OSS developers patch submission activities. We use these sets to predict whether a project participant will become a developer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a developer. Further, we find that this is true to the extent that other predictors, e. g. patch submission info, need not be included in the models. In addition, we show that future developers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10% of the three month data's predictions. Finally, we find that it is easier to become a developer earlier in the projects lifecycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2013","2025-04-25 15:54:30","2025-04-25 15:54:30","","340-349","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Software Improvement Grp; Lab Qual Software ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play a crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process. In detail, we analyze what review feedbacks encourage a contributor to continue with OSS project. Using a Qt project dataset, we build a prediction model to identify a LTC. We find that not only contributor's activities, but also a reviewer feedbacks, useful in identifying LTCs.","2018","2025-04-25 15:54:30","2025-04-25 15:54:30","","109-113","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Int Assoc & Comp & Informat Sci; IEEE Comp Soc Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation. We demonstrate how OSS and systematic conservation planning can be taken to the wider community to produce on-the-fly outputs. Our novel approach has the potential to build partnerships with community groups and give the community a sense of ownership in the decision-making process. It is more likely that conflicts will be minimised and negotiation hastened for a better MPA zoning outcome for all.","2005","2025-04-25 15:54:30","2025-04-25 15:54:30","","1525-1531","","","","","","","","","","","UNIV WESTERN AUSTRALIA","NEDLANDS, WA, AUSTRALIA","English","","","","","","","Type: Proceedings Paper","","","","GIS; Conservation Planning; Decision Support; Marine Protected Areas; Public Participation","","Zerger, A; Argent, RM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails. These emails contain decisions for 466 Python Enhancement Proposals (PEPs) that document the language's evolution.

However, that is not the only charge that propels contributions-growing interest in open source has also been attributed to software developers deciding to use their technical skills to benefit a common societal good. To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.","2021","2025-04-25 15:54:30","2025-04-25 15:54:30","","1020-1032","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT ISSN: 0270-5257 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We found that although workers valued the flexibility of working from home, they had difficulty focusing on their work for sustained time periods and often felt isolated. This motivated them to use coworking spaces - physical spaces used as work space by workers not on the same team or even the same firm - as a critical part of their space ecology. In conjunction with their media ecology - a mix of communication technologies including IRC - the space/media mix allowed them to balance their work and personal lives.

This approach re-scales Marchs (1991) framework and applies it to characterize the innovation system of a distributed organization of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two coupled processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from lurking (not contributing or contributing to projects without becoming a member) to laboring (joining one or more projects as members), and to launching (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered developers fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platforms global dynamics.","2008-08","2025-04-25 15:54:31","2025-04-25 15:54:31","","647-710","","4","17","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whereas I do agree with the authors on most points, I am less convinced that “existing management theory” will suffice to address the problem of “reset thinking”. In this article, I demonstrate that the economy-bias of existing theories is a gateway for “reset thinking” geared towards an allegedly necessary re-/socialisation of management and organisation. A research agenda on cronyism must therefore be complemented by one on privilege and hierarchy not only as undesirable side-effects of cronyism, but also as desired outcomes of advocacy for specific minorities or missions. As self-identifications with group interests or calls for missions have become popular in management theory, I conclude that this new appetite for privilege might undermine not only the higher ideals of many management theorists, but also the foundations of modern society.","2023-09","2025-04-25 15:54:31","2025-04-25 15:54:31","","","","3","39","","","","","","","","","","English","","","","","","","Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Management theory; Conservatism; Cronyism; Restorism; Stratification; The Great Reset","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Deep learning frameworks have been proposed to facilitate the development of such software systems, among which, PYTORCH and TENSORFLOW stand out as notable examples. Considerable attention focuses on exploring software engineering practices and addressing diverse technical aspects in developing and deploying deep learning frameworks and software systems. Despite these efforts, little is known about the open source software communities involved in the development of deep learning frameworks. In this article, we perform a comparative investigation into the open source software communities of the two representative deep learning frameworks, PYTORCH and TENSORFLOW. To facilitate the investigation, we compile a dataset of 2,792 and 3,288 code commit authors, along with 9,826 and 19,750 participants engaged in issue events on GITHUB, from the two communities, respectively. With the dataset, we first characterize the structures of the two communities by employing four operationalizations to classify contributors into various roles and inspect the contributions made by common contributors across the two communities. We then conduct a longitudinal analysis to characterize the evolution of the two communities across various releases, in terms of the numbers of contributors with various roles and role transitions among contributors. Finally, we explore the causal effects between community characteristics and the popularity of the two frameworks. We find that the TENSORFLOW community harbors a larger base of contributors, encompassing a higher proportion of core developers and a more extensive cohort of active users compared to the PYTORCH community. In terms of the technical background of the developers, 64.4% and 56.1% developers in the PYTORCH and TENSORFLOW communities are employed by the leading companies of the corresponding open source software projects, Meta and Google, respectively; 25.9% and 21.9% core developers in the PYTORCH and TENSORFLOW communities possess Ph.D. degrees, while 77.2% and 77.7% contribute to other machine learning or deep learning open source projects, respectively. Developers contributing to both communities demonstrate spatial and temporal similarities to some extent in their pull requests across the respective projects. The evolution of contributors with various roles exhibits a consistent upward trend over time in the PYTORCH community. Conversely, a noticeable turning point in the growth of contributors characterizes the evolution of the TENSORFLOW community. Both communities show a statistically significant decreasing trend in the inflow rates of core developers. Furthermore, we observe statistically significant causal effects between the expansion of communities and retention of core developers and the popularity of deep learning frameworks. Based on our findings, we discuss implications, provide recommendations for sustaining open source software communities of deep learning frameworks, and outline directions for future research.","2025-03","2025-04-25 15:54:31","2025-04-25 15:54:31","","","","3","34","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","GitHub; community evolution; Deep learning; developer classification","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It finds that both co-membership and watching contribute positively to OSS success, and thus shows the co-existence of both experiential learning and vicarious learning for OSS development.

For this system, the soft-output (SO) detector was recently proposed where a soft-metric (e.g., a log-likelihood ratio (LLR)) is computed from a hard-decision channel output by introducing a novel distance measure in the binary Hamming space. This makes it possible to be naturally incorporated into the state-of-the-art channel codes (e.g., low-density parity-check code or polar code). In this paper, we further improve the performance of the SO detector by exploiting a priori information (e.g., the previously decoded messages), which is called the one-bit successive-cancellation soft-output (OSS) detector. The key idea of the proposed OSS detector is that each user k's message is decoded sequentially via the associated channel decoder k in ascending order and a refined search-space is constructed using the previously decoded messages (i.e., the enhanced LLRs are generated). We then present a multiple OSS detector by taking into account a more practical scenario where the BS is equipped with multiple channel decoders. In addition, we propose an efficient way to determine a good decoding order by introducing a novel set-distance measure. Finally, simulation results demonstrate that the proposed OSS detector can significantly improve the existing SO detector for the coded MU-MIMO systems with one-bit ADCs.","2019","2025-04-25 15:54:31","2025-04-25 15:54:31","","27172-27182","","","7","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","Massive MIMO; multiuser MIMO detection; one-bit analog-to-digital converter (ADC); soft-output decoding.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to assist designers, many effective tools have been developed to support collaborative engineering, whose implementation is perceived as complex. Nowadays, industrial scenarios encourage companies to adopt PLM solutions, even if, sometimes, they can't understand the benefits. On the other hand, many free solutions with comparable functionalities are developed, which have been increasingly successful. In this article, we test different associations of software to make a comparison between free software and market solutions. In this experiment, 24 students in a Master's Degree course aimed to design mechanical products by using software to assist collaborative distributed design, using two different configurations. This experiment allowed us to compare design functionalities between free and commercial solutions, in order to determine ways to improve efficiency in a collaborative distributed design situation.

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.","2016-05","2025-04-25 15:54:31","2025-04-25 15:54:31","","","","2","25","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","Measurement; natural experiment; Human Factors; commercial involvement; contributor inflow; contributor retention; extent and intensity of involvement; Hybrid project","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to mitigate the impact of natural hazards on European economies and societies, improved risk assessment, and management needs to be pursued. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models have become an important part of flood risk management (FRM). In this context, free and open-source (FOSS) geospatial models provide better and more complete information to stakeholders regarding their compliance with the Flood Directive (2007/60/EC) for effective and collaborative FRM. A geospatial model is an essential tool to address the European challenge for comprehensive and sustainable FRM because it allows for the use of integrated social and economic quantitative risk outcomes in a spatio-temporal domain. Moreover, a FOSS model can support governance processes using an interactive, transparent and collaborative approach, providing a meaningful experience that both promotes learning and generates knowledge through a process of guided discovery regarding flood risk management. This article aims to organize the available knowledge and characteristics of the methods available to give operational recommendations and principles that can support authorities, local entities, and the stakeholders involved in decision-making with regard to flood risk management in their compliance with the Floods Directive (2007/60/EC).","2015-12","2025-04-25 15:54:31","2025-04-25 15:54:31","","2704-2727","","4","4","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source; GIS; flood risk management; flood risk model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various quantities of fiber were employed to obtain nonwoven mats with a fiber content ranging from 5 to 35 kg/m3. Thermal conductivity and thermal diffusivity were measured across diverse relative humidity levels and temperatures. Simultaneously, milkweed floss samples were exposed to identical environmental conditions to assess the moisture regain and specific heat capacities of the fiber. The specific heat capacity of milkweed and thermal conductivity of the nonwovens exhibited a linear increase with temperature. The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content. The thermal insulation properties of the nonwovens remained partially stable below 30% relative humidity but substantially deteriorated at higher levels. The nonwovens exhibited optimal thermal insulation properties at a fiber content between 20 and 25 kg/m3. The results of this study highlighted several technical advantages of employing milkweed floss as a sustainable and lightweight solution for thermal insulation.","2024-01","2025-04-25 15:54:31","2025-04-25 15:54:31","","","","1","8","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","milkweed floss; nonwoven mat; R-value; seed fibers; specific heat capacity; thermal conductivity; thermal resistance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Core contributors and peripheral contributors work together to create a successful project, each playing a different role. One-Time Contributors (OTCs), who are on the very fringe of the peripheral developers, are largely unstudied despite offering unique insights into the development process. In a prior survey, we identified OTCs and discovered their motivations and barriers. Aims: The objective of this study is to corroborate the survey results and provide a better understand of OTCs. We compare OTCs to other peripheral and core contributors to determine whether they are distinct. Method: We mined data from the same code-review repository used to identify survey respondents in our previous study. After identifying each contributor as core, periphery, or OTC, we compared them in terms of patch size, time interval from submission to decision, the nature of their conversations, and patch acceptance rates. Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate. The peripheral developers fall in between the OTCs and the core contributors. Conclusion: OTCs do, in fact, face the barriers identified in our prior survey. They represent a distinct group of contributors compared to core and peripheral developers.","2017","2025-04-25 15:54:31","2025-04-25 15:54:31","","1-10","","","","","","","International Symposium on Empirical Software Engineering and Measurement","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: ACM; IEEE; IEEE Comp Soc; IBM ISSN: 1938-6451 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key success factor is to respond to customers' desires to choose the billing scheme that suits their needs, to subscribe to all services as a service package, and to pay for them via a single bill regardless of service type, service location, service providers and network operators. Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task. This paper presents key OSS functions and an information model that tackle this complexity. Challenges are described and requirements are defined. Related efforts are highlighted, and the context surrounding this work is laid out in detail.

It is believed that the seed flosses of common milkweed, Asclepias Syriraca, may be a promising reinforcing fiber given its uncommon hollow microstructure that is associated with both high specific properties and outstanding insulating capacities. This study presents an overview of the properties of milkweed floss and its potential use in reinforced-polymer composites. Milkweed flosses from Quebec were analyzed to determine their overall dimensions, density, porosity, coefficient of acoustic absorption, thermal conductivity, thermal resistance, and elastic modulus. In parallel, a portion of milkweed fibers was treated with acetone to modify their surface, and the properties of the treated fibers were measured and compared against the characteristics of the original fibers. Infrared spectroscopy was employed to assess differences between the chemical groups on the surface of treated and native fibers. The treatment with acetone removed fatty acids, waxes, and free sugars from the fibers' surface. The acetone treatment did not affect the fibers' microstructure nor their acoustic absorption capacity. The acetone-treated fibers showed greater thermal resistance and a higher thermal conductivity than native milkweed floss. The elastic modulus of milkweed decreased by nearly 49% after the acetone treatment.","2023-04-24","2025-04-25 15:54:32","2025-04-25 15:54:32","","","","1","20","","","","","","","","","","English","","","","","","","Place: 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA Publisher: TAYLOR & FRANCIS INC Type: Article","","","","fiber microstructure; mechanical properties; Natural hollow fibers; reinforcing fiber; thermal properties; thermo-acoustic insulation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94% of the surveyed core developers agreed with our state model of inactivity; 71% and 79% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26%, with a similar to 54% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.","2022-05","2025-04-25 15:54:32","2025-04-25 15:54:32","","","","3","27","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Retention; Disengagement; Abandonment; Open-source communities; Repository mining; Turnover","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The recent growth in demand for professional software engineers has led to increased contributions to, and usage of, OSS. However, there is limited understanding of the factors affecting how developers, and how new or student developers in particular, decide which OSS projects to contribute to, a process critical to OSS sustainability, access, adoption, and growth. To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (p < 0.0001, effect size = 0.84), student motivation (p < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (p < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner. Our findings may help improve the experience for new developers participating in OSS4SG and the quality of their contributions. We also hope our work helps educators, project leaders, and contributors to build a mutually-beneficial framework for the future growth of OSS4SG.","2023","2025-04-25 15:54:32","2025-04-25 15:54:32","","3-15","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei Type: Proceedings Paper","","","","Open Source Software; CS Education; Social Good","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whether a project participant is initiated as a committer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e.g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving committer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different Apache Software Foundation OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e., OSS developers' patch submission activities. We use these sets to predict whether a project participant will become a committer, and to characterize their socialization patterns around the time of becoming committer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a committer. Further, we find that this is true to the extent that other predictors, e.g., patch submission info, need not be included in the models. In addition, we show that future committers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10 % of the three month data's predictions. Interestingly, we find that on average, for each project, one's level of socialization ramps up before the time of becoming a committer.

While code reviews are a common measure to catch bugs during development, they lack scalability, are error-prone, and time-consuming [2,38,41]. Thus, static analysis tools like Semgrep emerged to provide programmatic feedback on code. But static analyses often show low precision, which can jeopardize utility. In this case study, we investigate precision rates for Semgrep OSS for common web weaknesses from the OWASP Top 10 [35]. We explore method and tool limitations in weakness detection, OWASP classes, and Semgrep's public PHP rule set. We apply the latter to 300 open source applications, invest 34 h in manual sample validation, and derive precision rates for each OWASP class. Our validation shows that the rules correctly detected weaknesses for seven OWASP classes with 86% precision, demonstrating the tool's utility. Yet, we estimate that most findings are not exploitable (81%). Thus, there is still considerable assessment overhead for users. Our work further highlights that only a subset of weaknesses are detectable, as dimensions such as runtime context and insecure design remain hidden. Finally, we advise practitioners to not exclusively rely on public rules, as translating application-specific business logic and design choices may open up to the detection of previously uncovered weaknesses.","2024","2025-04-25 15:54:32","2025-04-25 15:54:32","","64-83","","","14828","","","","Lecture Notes in Computer Science","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","Backup Publisher: German Informat Soc, Special Interest Grp - Secur Intrus Detect & Response ISSN: 0302-9743 Type: Proceedings Paper","","","","","","Maggi, F; Egele, M; Payer, M; Carminati, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It will be shown how a Volume Conductor Model (VCM) is constructed and examined using Python-controlled algorithms for generation, discretization and adaptive mesh refinement of the computational domain, as well as for incorporation of heterogeneous and anisotropic properties of the tissue and allocation of neuron models. The utilization of the platform is facilitated by a collection of predefined input setups and quick visualization routines. The accuracy of a VCM, created and optimized by the platform, was estimated by comparison with a commercial software. The results demonstrate no significant deviation between the models in the electric potential distribution. A qualitative estimation of different physics for the VCM shows an agreement with previous computational studies. The proposed computational platform is suitable for an accurate estimation of electric fields during DBS in scientific modeling studies. In future, we intend to acquire SDA and EMA approval. Successful incorporation of open-source software, controlled by in-house developed algorithms, provides a highly automated solution. The platform allows for optimization and uncertainty quantification (UQ) studies, while employment of the open-source software facilitates accessibility and reproducibility of simulations.","2020-07","2025-04-25 15:54:32","2025-04-25 15:54:32","","","","7","16","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, previous work shows that OSS newcomers often face several barriers to contribute, which lead them to lose motivation and even give up on contributing. A well-known way to help newcomers overcome initial contribution barriers is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in OSS projects. Studying mentors' perspectives on the barriers that newcomers face play a vital role in improving onboarding processes; yet, OSS mentors face their own barriers, which hinder the effectiveness of the strategy. Since little is known about the barriers mentors face, in this paper, we investigate the barriers that affect mentors and their newcomer mentees. We interviewed mentors from OSS projects and qualitatively analyzed their answers. We found 44 barriers: 19 that affect mentors; and 34 that affect newcomers (9 affect both newcomers and mentors). Interestingly, most of the barriers we identified (66%) have a social nature. Additionally, we identified 10 strategies that mentors indicated to potentially alleviate some of the barriers. Since gender-related challenges emerged in our analysis, we conducted nine follow-up structured interviews to further explore this perspective. The contributions of this paper include: identifying the barriers mentors face; bringing the unique perspective of mentors on barriers faced by newcomers; unveiling strategies that can be used by mentors to support newcomers; and investigating gender-specific challenges in OSS mentorship. Mentors, newcomers, online communities, and educators can leverage this knowledge to foster new contributors to OSS projects.","2018-12","2025-04-25 15:54:32","2025-04-25 15:54:32","","679-714","","3-6, SI","27","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article; Proceedings Paper","","","","Onboarding; Open source software; Challenges; Coach; Difficulties; Joining process; Mentor; Newbie; Newcomer; Novice; Obstacles; Tutor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using social capital theory in a mixed methods case study, we compare entrepreneur and non-entrepreneur behaviors to investigate how entrepreneurs build social capital within an OSS community. This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation). Given the liabilities of newness and smallness as well as other challenges faced by entrepreneurs, applying an open innovation strategy in OSS communities could be one approach where entrepreneurs, by developing and freely revealing their intellectual property to the community, share their way to success via OSS-infused entrepreneurial business ventures.","2019-03","2025-04-25 15:54:33","2025-04-25 15:54:33","","23-40","","1","29","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Social capital; Entrepreneurship; Mixed methods case study; OSS Online communities; Virtual worlds","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As a first implementation, it is assumed that the forward models are perfect and that the radar data are sampled at the analysis grid points. A general purpose nonhydrostatic compressible model is used with the inclusion of complex multiclass ice microphysics. New aspects of this study compared to previous work include the demonstration of the ability of the EnKF method to retrieve multiple microphysical species associated with a multiclass ice microphysics scheme, and to accurately retrieve the wind and thermodynamic variables. Also new are the inclusion of reflectivity observations and the determination of the relative role of the radial velocity and reflectivity data as well as their spatial coverage in recovering the full-flow and cloud fields. In general, the system is able to reestablish the model storm extremely well after a number of assimilation cycles, and best results are obtained when both radial velocity and reflectivity data, including reflectivity information outside of the precipitation regions, are used. Significant positive impact of the reflectivity assimilation is found even though the observation operator involved is nonlinear. The results also show that a compressible model that contains acoustic modes, hence the associated error growth, performs at least as well as an anelastic model used in previous EnKF studies at the cloud scale. Flow-dependent and dynamically consistent background error covariances estimated from the forecast ensemble play a critical role in successful assimilation and retrieval. When the assimilation cycles start from random initial perturbations, better results are obtained when the updating of the fields that are not directly related to radar reflectivity is withheld during the first few cycles. In fact, during the first few cycles, the updating of the variables indirectly related to reflectivity hurts the analysis. This is so because the estimated background covariances are unreliable at this stage of the data assimilation process, which is related to the way the forecast ensemble is initialized. Forecasts of supercell storms starting from the best-assimilated initial conditions are shown to remain very good for at least 2 It.","2005-07","2025-04-25 15:54:33","2025-04-25 15:54:33","","1789-1807","","7","133","","","","","","","","","","English","","","","","","","Place: 45 BEACON ST, BOSTON, MA 02108-3693 USA Publisher: AMER METEOROLOGICAL SOC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many approaches have been devised in order to create an optimal bone scaffold capable of achieving desirable degrees of bone integration and osteogenesis. Osteogenesis represents a complex physiological process involving multiple cooperating systems. A tight relationship between the immune and skeletal systems has lately been established using the concept of “osteoimmunology,” since various molecules, particularly those regulating immunological and inflammatory processes, are shared. Inflammatory mediators are now being implicated in bone remodeling, according to new scientific data. In this study, a profiler PCR array was employed to evaluate the expression of cytokines and chemokines in human adipose derived-mesenchymal stem cells (hASCs) cultured on porous hydroxylapatite (HA)/Collagen derived Bio-Oss((R))/Avitene scaffolds, up to day 21. In hASCs grown on the Bio-Oss((R))/Avitene biomaterial, 12 differentially expressed genes (DEGs) were found to be up-regulated, together with 12 DEG down-regulated. Chemokine CCL2, which affects bone metabolism, tested down-regulated. Interestingly, the Bio-Oss((R))/Avitene induced the down-regulation of pro-inflammatory inter-leukin IL-6. In conclusion, our investigation carried out on the Bio-Oss((R))/Avitene scaffold indicates that it could be successfully employed in maxillofacial surgery. Indeed, this composite material has the advantage of being customized on the basis of the individual patients favoring a novel personalized medicine approach.","2022-06-27","2025-04-25 15:54:33","2025-04-25 15:54:33","","","","","10","","","","","","","","","","English","","","","","","","Place: AVENUE DU TRIBUNAL FEDERAL 34, LAUSANNE, CH-1015, SWITZERLAND Publisher: FRONTIERS MEDIA SA Type: Article","","","","biomaterial; chemokine; cytokine; immunomodulation; osteogenic differentiation; stem cells","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The aim of this study was to assess the adhesion and migration of dental stem cells on human pulp ceiling cavities filled with these endodontic materials in an experimental model, which mimics the clinical conditions of regenerative endodontics. Cavities were formed, by a homemade mold, on untouched third molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities' surface and their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three materials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential morphology. Moreover, variations were observed when comparing cells numbers on cavity's filling versus the surrounding dentine disc. The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss. This was confirmed in the migration assay where a statistically significant lower number of cells migrated towards Bio-Oss as compared to MTA and dentin chips. This study highlights that MTA and dentin chips have a greater potential compared to Bio-Oss regarding the attraction of dental stem cells and are good candidates for bioengineered pulp regeneration.","2015","2025-04-25 15:54:33","2025-04-25 15:54:33","","","","","2015","","","","","","","","","","English","","","","","","","Place: ADAM HOUSE, 3RD FLR, 1 FITZROY SQ, LONDON, W1T 5HF, ENGLAND Publisher: HINDAWI LTD Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to effectively promote the growth of online secondhand markets, this paper designs and validates a scale to assess customer perception of the service quality of secondhand products purchased via online platforms. Complementarily, the paper assesses how each of the different dimensions that configure the scale contributes to explaining the fulfillment of customers' expectations. The scale is defined by 23 items and is arranged in 5 dimensions from the literature on online commerce as well as on the sharing economy. A sample of 200 questionnaires is used for exploratory factor analysis. A second sample of 507 users is used for confirmatory factor analysis. The quality perceived by online customers of secondhand products depends on the quality of the interactions that they have with the website, with the vendor, and with the product. The dimension that contributes the most to customer fulfillment of expectations is product quality. Findings identify the items that contribute the most to quality perception and fulfillment of expectations, facilitating the development of more effective strategies for platform owners and vendors who want to attract and retain customers of secondhand products. Complementarily, these findings are useful to businesses and governments that want to promote a more sustainable economy by reducing consumption of new products and promoting reutilization of existing ones.","2020-11","2025-04-25 15:54:33","2025-04-25 15:54:33","","","","21","12","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","online; quality; fulfillment of expectations; secondhand","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: Sixty-eight patients who had difficulty in cannulation into the papilla located at the lower, left, or right side of the periampullary diverticulum upon endoscopic retrograde cholangiopancreatography (ERCP) were recruited at Taizhou Hospital from July 2016 to June 2020. A random number table was used to divide the patients into an intervention (with titanium clip-dental floss traction) group and a control group (n=34 in each group). Patients in both groups underwent ERCP. The cannulation time, cannulation success rate, incidence of postprocedural complications after ERCP, hospitalization time, and hospitalization expenses in the 2 groups were compared. Result: The cannulation time was 15.3 +/- 4.1 minutes in the intervention group, which was less than that in the control group (25.7 +/- 6.5 min). The cannulation success rate was 77 +/- 12.1% in the intervention group, which was higher than that in the control group (43 +/- 16.7%). Postprocedural complications occurred in 2 patients in the intervention group and 6 patients in the control group, with no significant differences.

From August to November 2014, a total of 95 patients with 104 gastric epithelial neoplasms underwent DFC-ESD (DFC group). Historical controls treated by conventional ESD (control group) were individually matched to cases at a 1:1 ratio by lesion location, ulcer findings, resected specimen size, and the proficiency of the operator (trainee/expert). The outcomes of the procedure in the two groups were then compared. The mean +/- A SD procedure time was 43 +/- A 24 min in the DFC group and 52 +/- A 30 min in the control group (P < 0.01). Fewer lesions in the DFC group needed > 80 min compared with the control group (3-vs-16 cases, P = 0.01). There were no significant differences in adverse events between the groups. Perforation and delayed bleeding occurred in one and four lesions, respectively, in the DFC group, and three and nine in the control group. En bloc resection was achieved in all cases. No significant differences were found regarding curability of ESD between the groups. DFC effectively reduced ESD procedure time without increasing adverse events.

Considering that traditional salinity reconstruction methods often suffer from various factors such as additional constraints, priori physical assumptions and large of specific regression coefficients, a generative adversarial networks (GANs) based deep learning (DL) framework is proposed to directly construct a near real-time, high-resolution daily three-dimensional ocean subsurface salinity (3D OSS) dataset from a data driven perspective in this study. Four models with different structural combinations are designed in the China's marginal seas. Experimental results demonstrate that the models can successfully reconstruct the high-precision and high-resolution 3D OSS on a daily scale in 12 depth levels (from 2 m to 200 m). The asymmetric inception3DGAN model with all enhanced structures has the highest accuracy, the average root-mean-squared error (RMSE) is 0.135psu, the average coefficient of determination (R2) is 0.5641 and the percent bias is 0.436%. Comparing with model without enhanced structures, the average RMSE is decreased by 22.41% when adding all the enhancement structures. Besides, temporal and spatial error analysis are also conducted to evaluate the models' performance from different aspects. Finally, the model results are used to analyze common ocean elements, such as water mass properties, dynamic fields and geostrophic velocity fields, demonstrating that the 3D OSS dataset construction approach proposed in this study not only provides some new insights into ocean observations, but also has high application values.","2023-08","2025-04-25 15:54:33","2025-04-25 15:54:33","","","","","184","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Deep learning; Data-driven; Generative adversarial networks; Ocean subsurface salinity; T-S mapping","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Increasingly complex simulations are used to assess similarities and differences between the two models' components. The simulations presented here are forced by ocean currents from a Finite Volume Community Ocean Model (FVCOM) implementation that has excellent skill in representing tidal motion, and with observed wind data that compensates for a coarse vertical ocean model resolution. The comprehensive comparison between GNOME and BLOSOM presented here, should aid modelers in interpreting their results. Beyond many similarities, aspects where both models are distinct are highlighted. Some suggestions for improvement are included, e.g., the inclusion of temporal interpolation of the forcing fields (BLOSOM) or the inclusion of a deflection angle option when parameterizing wind-driven processes (GNOME). Overall, GNOME and BLOSOM perform similarly, and are found to be complementary oil spill models. This paper also sheds light on what drove the historical Point Wells spill, and serves the additional purpose of being a learning resource for those interested in oil spill modeling. The increasingly complex approach used for the comparison is also used, in parallel, to illustrate the approach an oil spill modeler would typically follow when trying to hindcast or forecast an oil spill, including detailed technical information on basic aspects, like choosing a computational time step. We discuss our successful hindcast of the 2003 Point Wells oil spill that, to our knowledge, had remained unexplained. The oil spill models' solutions are compared to the historical Point Wells' oil trajectory, in time and space, as determined from overflight information. Our hindcast broadly replicates the correct locations at the correct times, using accurate tide and wind forcing. While the choice of wind coefficient we use is unconventional, a simplified analytic model supported by observations, suggests that it is justified under this study's circumstances. We highlight some of the key oceanographic findings as they may relate to other oil spills, and to the regional oceanography of the Salish Sea, including recommendations for future studies.","2018-09","2025-04-25 15:54:33","2025-04-25 15:54:33","","","","3","6","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","BLOSOM; Foss Barge; GNOME; hindcast; model comparison; ocean trajectory; oil spill model; Point Wells; Salish Sea; windage","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of the male narrator is inseparably bound up with a number of compromises for the woman writer and for the female reader. But being thus `compromised' through vicariously living the experience of the masculine Other also allows the woman writer privileged insight into the complex processes of justification and rationalisation through which the masculine world-view is engendered and sustained in narrative; it allows her imaginatively to work through, and to see through, the tangle of cause and effect relations which are often illegitimately marshalled into support of that view, and to cast ironical and critical light on them.","2004-04","2025-04-25 15:54:33","2025-04-25 15:54:33","","230-250","","59","","","","","","","","","","","English","","","","","","","Place: CAHIERS VICTORIENS EDOUARDIENS PO 5043, 34032 MONTPELLIER-CEDEX, FRANCE Publisher: UNIV PAUL VALERY Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Satellite remote sensing is the optimal tool to provide such data. Images from Synthetic Aperture Radar (SAR) satellite sensors are preferably used as they work regardless of cloud coverage during image acquisition. However, processing of SAR is more complicated and the sensors have development potential. Dealing with such a complexity, current studies should aim to be reproducible, open, and built upon free and open-source software (FOSS). Thereby, the data can be reused to develop and validate new algorithms or improve the ones already in use. This paper presents a case study of crop classification from microwave remote sensing, relying on open data and open software only. We used 70 multitemporal microwave remote sensing images from the Sentinel-1 satellite. A high-resolution, high-precision digital elevation model (DEM) assisted the preprocessing. The multi-data approach (MDA) was used as a framework enabling to demonstrate the benefits of including external cadastral data. It was used to identify the agricultural area prior to the classification and to create land use/land cover (LULC) maps which also include the annually changing crop types that are usually missing in official geodata. All the software used in this study is open-source, such as the Sentinel Application Toolbox (SNAP), Orfeo Toolbox, R, and QGIS. The produced geodata, all input data, and several intermediate data are openly shared in a research database.

However, no traction method using the thread and clip for duodenal ESD as described in this article has been reported to date. We report a case in which traction-assisted ESD using dental floss and a clip was successfully performed on a huge superficial nonampullary duodenal epithelial tumor accompanied by severe fibrosis caused by preoperative biopsies. A 65-year-old woman had a 55-mm flat-elevated tumor in the second part of the duodenum. Severe fibrosis of the submucosal layer was expected due to repeated biopsies at the same site by the patient's previous endoscopist. We selected ESD for this lesion, and the initial incision was started from the side proximal to the lesion, but it was difficult to insert the scope under the submucosal layer directly beneath the biopsy scar. Therefore, traction with an endoclip and dental floss was performed to lift the lesion. Excellent traction allowed safe resection of the fibrotic part under accurate visual observation. Finally, the lesion was resected en bloc without adverse events. Traction-assisted ESD using dental floss and a clip is likely to be an effective adjunctive technique for quick, safe, and successful resection of lesions in the duodenum on which it is difficult to perform ordinary ESD and that have a high probability of intraoperative perforation and massive bleeding.","2019-04","2025-04-25 15:54:34","2025-04-25 15:54:34","","179-181","","2","3","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","dental floss; duodenal endoscopic submucosal dissection; severe fibrosis; superficial nonampullary duodenal epithelial tumor; traction-assisted endoscopic submucosal dissection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bio-Oss (R) is a deproteinized, sterilized bovine bone that has been extensively used in bone regeneration procedures. The aim of the present study was a comparative light, scanning, and electron microscopy evaluation of the interface between Bio-Oss (R) and bone in specimens retrieved after sinus augmentation procedures. Under light microscopy, most of the particles were surrounded by newly formed bone, while in a few cases, at the interface of some particles it was possible to observe marrow spaces and biological fluids. Under scanning electron microscopy, in most cases, the particle perimeter appeared lined by bone that was tightly adherent to the biomaterial surface. Transmission electron microscopy showed that the bone tissue around the biomaterial showed all the phases of the bone healing process. In some areas, randomly organized collagen fibers were present, while in other areas, newly formed compact bone was present. In the first bone lamella collagen fibers contacting the Bio-Oss (R) surface were oriented at 243.73 +/- 7.12 degrees (mean +/- SD), while in the rest of the lamella they were oriented at 288.05 +/- 4.86 degrees (mean +/- SD) with a statistically significant difference of 44.32 degrees (p < 0.001). In the same areas the intensity of gray value was 172.56 +/- 18.15 (mean +/- SD) near the biomaterial surface and 158.71 +/- 21.95 (mean +/- SD) in the other part of the lamella with an unstatistically significant difference of 13.79 (P = 0.071). At the bone-biomaterial interface there was also an electron-dense layer similar to cement lines. This layer had a variable morphology being, in some areas, a thin line, and in other areas, a thick irregular band. The analyses showed that Bio-Oss (R) particles do not interfere with the normal osseous healing process after sinus lift procedures and promote new bone formation. In conclusion, this study serves as a better understanding of the morphollogic characteristics of Bio-Oss (R) and its interaction with the surrounding tissues.

Preliminary method for the A50 road link (Eindhoven-Oss, The Netherlands)","ECOLOGICAL ENGINEERING","","0925-8574","10.1016/S0925-8574(96)00024-9","","After years of efforts to avoid or reduce the impact of infrastructure projects on nature, the principle of ecological compensation has been incorporated in Dutch governmental policy. Ecological compensation aims to recover those ecological functions and natural values that still remain affected after maximum effort has been made to reduce the impact of the intervention (mitigation). The accepted aim of current policy is thus no-net-loss of area and quality by means of mitigative and compensatory measures. As part sf the planning process for construction of a stretch of road in The Netherlands, viz,, the A50 road link in the province of North Brabant, a Nature Compensation Plan (NCP) was required to be drawn up. This work has recently been completed by the Regional Directorate of Public Works and Water Management, the initiator of the intervention. The NCP, initially presented as a Draft Plan, was drawn up by the Regional Directorate using a preliminary method designed by the Centre of Environmental Science of Leiden University for deriving compensatory measures. After an opportunity for public comment, the Draft Plan was revised to form a Final NCP. This article describes, firstly, the preliminary method for deriving ecological compensatory measures. The method starts by quantifying the effects of habitat loss, habitat disturbance (by changes in noise emissions, in the water table and in outdoor recreational patterns), barrier action and fauna casualties. Following mitigation of impacts on nature, compensation for non-mitigable effects focuses successively on area size, derived from the impact on breeding birds, and on area quality, derived from the habitat requirements of the vegetation and fauna groups affected by the road. Guidelines for identifying appropriate locations for compensation are also formulated. Secondly, the compensation method is applied to calculate the mitigative and compensatory measures for the A50 trajectory between Eindhoven and Oss. Thirdly, two comparisons are made: the Draft NCP is compared with the results of the preliminary method, and the Draft and the Final NCP are compared with one another in order to identify the role of the interest groups that played a major role in commenting on the Draft Plan. Finally, realization of the compensatory measures and development of the preliminary method itself are discussed. On the basis of the experience with the A50 case study, a more robust compensation method for road projects is to be developed.","1996-12","2025-04-25 15:54:34","2025-04-25 15:54:34","","327-349","","4","7","","","","","","","","","","English","","","","","","","Place: PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS Publisher: ELSEVIER SCIENCE BV Type: Article; Proceedings Paper","","","","mitigation; barrier action; fauna casualties; habitat disturbance; habitat loss; no-net-loss of area and quality; road infrastructure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of present study was to fully characterize our anorganic bone, InterOss (R), by physical and chemical methods and to compare it with another anorganic bone, Bio-Oss (R) that has been commercially distributed in dental bone graft substitute market since 1995. InterOss (R) anorganic bone had been successfully prepared by chemical treatment (NaOH and H2O2) and low temperature (350 degrees C) annealing process with an extremely low heating rate (<0.3 degrees C min(-1)). Commercially available Bio-Oss (R) anorganic bone was chosen for comparison. The physical and chemical analysis indicated that the pore structure, microstructure, phase structure, and chemical composition of InterOss (R) is substantially equivalent to that of Bio-Oss (R). The BET analysis also showed that the inner surface area of InterOss (R) is comparatively higher than that of Bio-Oss (R). Specially, the protein analysis showed that the content of residual protein of InterOss (R) is relatively lower than that of Bio-Oss (R). Based on an equivalency to Bio-Oss (R) in terms of physical and chemical characterization with both higher inner surface area and lower residual protein content, the InterOss (R) can be a promising candidate as dental bone grafting material in periodontal and maxillofacial surgery.

The antioxidant tea polyphenol (TPP) was embedded into W/O microemulsion, which was further encapsulated into multiple emulsion (Multi-E) together with functional soluble dietary fiber (SDF). The physicochemical properties indicated that the nanoemulsion-based edible film (NEF) improved the morphology of FF and reduced the crystallinity of the film by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water vapor permeability increased gradually and rose to only 0.99% after 5 h, resulting in the water activity of FF at a low level (<= 0.51) during the storage period. The TPP inside was released at a constant rate (<= 18.10%) on the surface, and such a rate was accelerated in the simulated gastrointestinal environment, especially in intestine reaching 60.12% after 5 h of digestion. Besides, the effect of NEF on the flavor was also evaluated and the contents of ketones, phenols, and pyrazines increased, which displayed a regulating effect on the overall flavor of FF by blocking the external moisture and suppressing the microorganism activity. In summary, the NEF effectively enhanced the flavor and taste of FF, controlled the release of TPP, and reduced the water activity during the storage, thereby extending the shelf life.","2022-07","2025-04-25 15:54:34","2025-04-25 15:54:34","","2370-2380","","7","10","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","controlled release; fish floss; nanoemulsion-based edible coating; shelf life; water activity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At 300 mu g/mL concentration, the SFSB extract exhibited the highest inhibition percentages of 83.33 and 86.67 for R. solani and F. oxysporum, respectively. In addition to its antimicrobial activity, SFSB extract exhibited strong antioxidant activity (IC50 value of 140.88 g/mL). HPLC analysis of the extract revealed the presence of various phenolic acids and flavonoids. Among these compounds, naringenin (18,698.83 mu g/g), chlorogenic acid (2727.49 mu g/g), ferulic acid (1276.18 mu g/g), syringic acid (946.26 mu g/g), gallic acid (812.34 mu g/g), and methyl gallate (651.73 mu g/g) were found to be the most abundant constituents. GCMS analysis showed that there were antimicrobial compounds like terpenoids, benzoic acid derivatives, phthalate esters, and different fatty acids. Isopropyl myristate was the most common compound, with a relative abundance of 55.61%. To our knowledge, this is the first investigation on the phytochemical composition and antimicrobial properties of SFSB extract. Consequently, utilizing SFSB extract could hold significant potential as a sustainable and natural approach for controlling and mitigating plant diseases.","2023-08","2025-04-25 15:54:34","2025-04-25 15:54:34","","","","8","9","","","","","","","","","","English","","","","","","","Place: MDPI AG, Grosspeteranlage 5, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","antibacterial; antifungal; antioxidant; DPPH; extract; GCMS; HPLC; ITS; phylogenetic; potato (Solanum tuberosum); silk floss","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. Conclusions and Practical Implications. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.","2016-12","2025-04-25 15:54:34","2025-04-25 15:54:34","","974-978","","12","147","","","","","","","","","","English","","","","","","","Place: 211 E CHICAGO AVE, CHICAGO, IL 60611 USA Publisher: AMER DENTAL ASSOC Type: Article","","","","dental floss; allergy; chronic periodontitis; contact hypersensitivity; plasma cell; Treatment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various types of bone graft materials are used after a sinus lift. In our study, a three-dimensional image analysis using a volume analyzer was performed to measure and compare the volume of demineralized bovine bone mineral (Bio-Oss (R)) and carbonate apatite (Cytrans (R)) after a sinus lift, as well as the amount of bone graft material resorption. Patient data were collected from cone-beam computed tomography images taken before, immediately following, and 6 months after the sinus lift. Using these images, both the volume and amount of resorption of each bone graft material were measured using a three-dimensional image analysis system. Results The amount of bone resorption in the Bio-Oss (R)-treated group was 25.2%, whereas that of the Cytrans (R)-treated group was 14.2%. A significant difference was found between the two groups (P < 0.001). Conclusions Our findings indicate that the volume of bone resorption was smaller in the Cytrans (R)-treated group than in the Bio-Oss (R)-treated group, suggesting that Cytrans (R) is more promising for successful implant treatments requiring a sinus lift.","2021-03-23","2025-04-25 15:54:34","2025-04-25 15:54:34","","","","1","7","","","","","","","","","","English","","","","","","","Place: SHIROYAMA TRUST TOWER 5F, 4-3-1 TORANOMON, MINATO-KU, TOKYO, 105-6005, JAPAN Publisher: SPRINGER JAPAN KK Type: Article","","","","Bio-Oss® CBCT; Cone-beam computed tomography; Cytrans® Dental implant; Maxillary sinus augmentation; Sinus lift","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We report here on the feasibility and efficacy of traction using dental floss with endoscopic clip to facilitate ESD versus conventional method for ESD trainees. Twenty simulated gastric lesions, paired with location and size, were created in porcine stomachs using a standard template. After a circular incision was made, submucosal dissection (control, n = 10) was performed with standard ESD, while the study (clip, n = 10) was performed with traction using dental floss and endoclip. Primary outcome was speed of submucosal dissection. Secondary outcome included frequency of submucosal injection and adverse event. Compared with controls, median procedure time was significantly shorter in the clip group (5.6 +/- A 1.1 vs. 13.6 +/- A 2.5 min, P = 0.003), with a significantly faster submucosal dissection time (1.8 +/- A 0.3 vs. 0.6 +/- A 0.1 cm(2)/min, P = 0.001) and less frequent submucosal injection (5.7 +/- A 0.6 vs. 8.5 +/- A 1.0 times, P = 0.024). There were no perforations in either group, but less adverse events (bleeding and injury to muscularis propria) in the clip group (1 vs. 7, P = 0.068, alpha = 0.1).

The purpose of this study was to radiologically evaluate the efficacy of using Bio-Oss Collagen with Concentrated Growth Factor (CGF) as grafting materials for OSFE with simultaneous implant placement in the atrophic maxilla after one year of functional loading.MethodsA total of 126 implants were placed for 123 patients. Our inclusion criteria were patients with Residual Bone Height (RBH) <= 5 whom underwent OSFE procedure and simultaneous implant placement with different grafting materials: Group A with no grafting materials, Group B with Bio-Oss bone graft, and Group C with Bio-Oss Collagen with CGF. The Implants Survival Rate (ISR) was the primary outcome variable. Secondary outcome variables included radiographic measurements assessed at four follow-up time points, the Implant Stability Quotient (ISQ), and bone density (B). Indicators of bone formation were compared at different time points. Appropriate statistical analyses were conducted, with statistical significance set at a P value of 0.05 for all tests.ResultsISR was 96%. A significant positive relationship was found between RBH and ISR, [r (126) = .359, p = .000]. Endo sinus bone gain indictors increased in both grafted groups as compared to the non-grafted group. Total Bone Resorption (TBR1) and (TBR2) significantly decreased in both grafted groups compared to the non-grafted group (P = .004, P = .000). Graft size (D) was a positive predictor for ISR at three time points: D0 (odds ratio [OR] 8.06; 95% CI 1.59 to 38.24; P = .010); D1 (OR 96.58; 95% CI 1.69 to 5.52; P = .027); D2 (OR 4.97; 95% CI 1.29 to 19.19; P = .020).

With advances in digital planning, surgical techniques, orthognathic surgery becomes increasingly safe, however, still a physiological factor that challenges the surgeon: bone repair. The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss (R) Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss (R)) and 10% collagen fibres in a block form and is sterilized by gamma-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss (R) Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss (R) Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.","2023-09-10","2025-04-25 15:54:35","2025-04-25 15:54:35","","","","","5","","","","","","","","","","English","","","","","","","Place: FLAT-RM C 16F, KINGS WING PLAZA 1, NO 3 KWAN ST, SHATIN, HONG KONG 00000, PEOPLES R CHINA Publisher: AME PUBLISHING COMPANY Type: Article","","","","biomaterial; Bio-Oss (R) Collagen; case report; orthognathic; Orthognathic surgery; pseudoarthrosis treatment; vertical chin augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Effective regeneration of bone defects resulting from peri-implantitis is crucial to maintaining the functionality of dental implants. Purpose of the Study: The study aimed to compare the effectiveness of fine-particle dentin and Bio-Oss in the reconstruction of bone defects caused by peri-implantitis. Materials and Methods: The study included a comprehensive radiological assessment of changes in bone density over time. Bone density was assessed using Hounsfield Units (HUs) as a measure of bone attenuation, with radiological assessments performed at 8- and 12-week intervals during the healing process. The study included participants ranging in age from 30 to 65 years. Fifty-seven patients were divided into three groups: 22 patients received small-particle dentin, 15 received Bio-Oss, and 20 controls without bone substitute material. Results: The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine dentin group, 85% in the Bio-Oss group, and 70% in the control group. The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine-dentin group, 85% in the Bio-Oss group, and 70% in the control group. Conclusions: Both fine-particle dentin and Bio-Oss significantly improved bone density compared to the control group. Fine-particle dentin is suitable for immediate bone regeneration due to its rapid initial regeneration, while Bio-Oss provides long-term support, ideal for maintaining implant stability over a longer period of time. The results highlight the importance of selecting appropriate bone replacement materials depending on the clinical scenario to improve patient outcomes after dental implant placement.","2024-08","2025-04-25 15:54:35","2025-04-25 15:54:35","","","","16","13","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","Bio-Oss; bone regeneration; bone substitute materials; periimplantitis; small-particle dentin","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Method and Result: A 77-year-old woman with a non-healing anteromedial chest wound presented with sudden hypotension and hemoptysis. The computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of ascending aorta, with sternal erosion close to the wound. Conventional open repair was not preferred due to possible contamination of interposition graft and difficult sternum closure. The feasibility of endografting was confirmed based on appropriate landing zones. After endografts modification at back table, we made a left minithoracotomy and establish a through-and-through body floss wire from left ventricular apex to femoral artery. Retrograde delivery over this wire from femoral artery to ascending aorta and deployment of endografts under rapid ventricular pacing support were performed smoothly. Final angiography showed no endoleaks with patent coronary and arch vessels. Further wound debridement was done at the same time and wound culture yielded tuberculosis. After completing anti-tuberculosis therapy, no recurrent infection occurred. Postoperative 6-month CT scan disclosed optimal result. Conclusion: With adequate landing zones and delicate surgical strategy, endografting with anti-tuberculosis therapy may be an alternative treatment for ascending aortic tuberculosis pseudoaneurysm.","2017-11","2025-04-25 15:54:35","2025-04-25 15:54:35","","","","","45","","","","","","","","","","English","","","","","","","Place: 360 PARK AVE SOUTH, NEW YORK, NY 10010-1710 USA Publisher: ELSEVIER SCIENCE INC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community - eZ Publish we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm.

We conducted a large, multicenter, prospective, observational study to confirm the REGOMA data in a real-world setting. Patients and methods: The major inclusion criteria were histologically confirmed diagnosis of glioblastoma according to the World Health Organization (WHO) 2016 classification and relapse after radiotherapy with concurrent/adjuvant temozolomide treatment, good performance status [Eastern Cooperative Oncology Group performance status (ECOG PS 0-1)] and good liver function. Regorafenib was administered at the standard dose of 160 mg/day for 3 weeks on/1 week off. Brain magnetic resonance imaging was carried out within 14 days before starting regorafenib and every 8-12 weeks. The primary endpoint was overall survival (OS). The secondary endpoints were progression -free survival (PFS), objective response rate, disease control rate (DCR), safety and health-related quality of life. The Response Assessment in Neuro-Oncology (RANO) criteria were used for response evaluation and Common Terminology Criteria for Adverse Events (CTCAE) version 5 for assessment of adverse events (AEs). Results: From September 2020 to October 2022, 190 patients with recurrent glioblastoma were enrolled from 30 cancer centers in Italy: their median age was 58.5 years [interquartile range (IQR) 53-67 years], 68% were male and 85 (44.7%) were in optimal clinical condition (ECOG PS 0). The number of patients taking steroids at baseline was 113 (60%); the second surgery was carried out in 39 (20.5%). O6-methylguanine-DNA methyltransferase (MGMT) was methylated in 80 patients (50.3%) and 147 (92.4%) of the patients analyzed had isocitrate dehydrogenase (IDH) wild type. The median follow-up period was 20 months (IQR 15.6-25.5 months). The median OS was 7.9 months ([95% confidence interval (CI) 6.5-9.2 months] and the median PFS was 2.6 months (95% CI 2.3-2.9 months). Radiological response was partial response and stable disease in 13 (7.3%) and 26 (14.6%) patients, respectively, with a DCR of 21.9%. The median number of regorafenib cycles per patient was 3 (IQR 2.0-4.0). Grade 3-4 drug-related adverse events were reported in 22.6% of patients. A dose reduction due to AEs was required in 36% of patients. No deaths were considered as treatment-related AEs. Conclusions: This large, real -world observational study showed similar OS with better tolerability of regorafenib in patients with relapsed glioblastoma compared with the REGOMA study.","2024-04","2025-04-25 15:54:35","2025-04-25 15:54:35","","","","4","9","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","glioblastoma; real-world; recurrent; REGOMA; regorafenib","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We aimed to compare the impact of early palliative care including formal concertation with oncologists on decision for an additional line of chemotherapy compared with usual oncology care. Methods This randomized prospective study enrolled adult women with metastatic breast cancer and visceral metastases with a 3rd- or 4th-line chemotherapy (CT). Patients received usual oncology care with a palliative care consultation only upon patient or oncologist request (standard group, S) or were referred to systematic palliative care consultation including a regular concertation between palliative care team and oncologists (early palliative care group, EPC). The primary endpoint was the rate of an additional CT (4th or 5th line) decision. Quality of life, symptoms, social support and satisfaction were self-evaluated at 6 and 12 months, at treatment discontinuation or 3 months after discontinuation. Results From January 2009 to November 2012, two authorized cancer centers included 98 women (EPC: 50; S: 48). Thirty-seven (77.1%, 95%CI 62.7-88%) patients in the EPC group had a subsequent chemotherapy prescribed and 36 (72.0%, 95%CI 57.5-83.8%) in the S group (p = 0.646). No differences in symptom control and global quality of life were observed, but less deterioration in physical functioning was reported in EPC (EPC: 0 [- 53-40]; S: - 6; 7 [- 60 to - 20]; p = 0.027).

Based on the results of the ISG/OS-1 study, the MAP regimen (methotrexate [MTX], doxorubicin [ADM] and cisplatin [CDP] with the addition of ifosfamide [IFO] in poor-responder patients) was investigated in patients with nonmetastatic osteosarcoma of the extremity (ISG/OS-Oss study). Patients and methods. Compared with the ISG/OS-1 study (cumulative doses: ADM 420 mg/m(2), MTX 120 g/m(2), CDP 600 mg/m(2), IFO 30 g/m(2)), the ISG/OS-Oss study reduced the number of MTX cycles from 10 to 5 (cumulative MTX dose: 60 g/m(2)) in order to diminish treatment duration and toxicity. Results. From January 2007 to June 2011, 171 patients (median age 16 years, 60% males) were registered. The limb salvage rate was 94% and the good pathologic response rate 51% (these figures were 92% and 48%, respectively, in the ISG/OS-1 study). At a median follow-up of 39 months (range, 4-80), the 5-year overall survival rate was 80% (95% CI, 73%-87%) and the event-free survival was 50% (95% CI, 39%-59%). For comparison, the 5-year overall and event-free survival rates in ISG/OS-1 were 73% (95% CI, 65%-81%) and 64% (95% CI, 56%-73%), respectively. Conclusions. This study confirms that in nonmetastatic osteosarcoma of the extremity, conservative surgery in more than 90% and a good pathologic response rate of 50% can be expected with primary chemotherapy based on the MAP regimen. The response and resection rates in the ISG/OS-Oss study are in the same range as those of the previous study, whereas the event-free survival is lower than that previously achieved. Since the only difference between the two studies was the cumulative dose of postoperatively given MTX, our data support the importance of the cumulative dose of MTX in the MAP regimen.","2014-12","2025-04-25 15:54:35","2025-04-25 15:54:35","","612-619","","6","100","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","methotrexate; neoadjuvant chemotherapy; osteosarcoma; tumor necrosis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Mean differences were expressed with the standard deviation and 95% confidence interval. The level of significance was 0.05. Survival of the suprastructures and implants was 100% with both treatment modalities. No significant difference in any of the outcome measures was observed between the test and control groups. High patient satisfaction and a significant improvement in quality of life were observed with both treatment modalities.

Anorganic bovine bone (Bio-Oss) has been reported to be osteoconductive, and no inflammatory responses have been observed with the use of this biomaterial. One of the main questions pertaining to Bio-Oss concerns its biodegradation and substitution by host bone. Some investigators have observed rapid replacement by host bone, while other researchers observed slow resorptive activity or no resorption at all. The aim of the present study was to conduct a long-term histologic analysis of retrieved specimens in humans where Bio-Oss was used in sinus augmentation procedures. Specimens were retrieved from 20 patients after varying peri ods from 6 months to 4 years and were processed to obtain thin ground sections. Bio-Oss particles were surrounded for the most part by mature, compact bone. In some Haversian canals it was possible to observe small capillaries, mesenchymal cells, and osteoblasts in conjunction with new bone. No gaps were present at the interface between the Bio-Oss particles and newly formed bone, in specimens retrieved after 18 months and 4 years, it was also possible to observe the presence of osteoclasts in the process of resorbing the Bio-Oss particles and neighboring newly formed bone. Bio-Oss appears to be highly biocompatible and osteoconductive, is slowly resorbed in humans, and can be used with success as a bone substitute in maxillary sinus augmentation procedures.","1999-12","2025-04-25 15:54:35","2025-04-25 15:54:35","","835-840","","6","14","","","","","","","","","","English","","","","","","","Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC Type: Article","","","","anorganic bovine bone; biomaterials; sinus augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

BMSCs obtained from rabbits were transfected with bFGF gene-encoding plasmids and proliferation rate and the differentiation marker alkaline phosphatase activity were measured. Following seeding into Bio-Oss collagen and 9-day culture in vitro, the surface morphology of the Bio-Oss was assessed using scanning electron microscopy analysis. Three mandibular defects were induced in the lower border of the bilateral mandibular ramus in each New Zealand white rabbit (total n=6). Three scaffolds, group A (seeded with BMSCs/bFGF), B (seeded with BMSCs/pVAX1) and C (cell-free), which had been cultured in vitro under standard cell culture conditions for 18 days, were implanted into mandibular defects under sterile conditions. Animals were sacrificed by anesthesia overdose 12 weeks following surgery and the scaffolds were extracted for bone mineral density and histological analyses. Results indicate that bFGF was successfully transfected into BMSCs. Proliferation and osteoblast differentiation of BMSCs were stimulated by bFGE: in vitro. No differences were identified in surface morphology for Bio-Oss loaded with variable groups of cells. At week 12 following implantation of Bio-Oss scaffolds, mineralization of BMSCs in Bio-Oss scaffolds was observed to be increased by bFGF. New bone and cartilage formation was revealed in hematoxylin and eosin-stained sections in Bio-Oss scaffolds and was most abundant in group A (BMSCs transfected with bFGF). In the current study, the bFGF gene was transfected into BMSCs and expressed successfully. bFGF promoted proliferation and differentiation of BMSCs in vitro and implantation of bFGF-expressing BMSCs combined with Bio-Oss enhanced new bone regeneration more effectively than traditional methods.","2013-01","2025-04-25 15:54:36","2025-04-25 15:54:36","","99-104","","1","7","","","","","","","","","","English","","","","","","","Place: POB 18179, ATHENS, 116 10, GREECE Publisher: SPANDIDOS PUBL LTD Type: Article","","","","Bio-Oss; basic fibroblast growth factor; bone marrow stromal cells; mandibular defect","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This involved a total of 15 sinus floor elevation procedures being carried out on 11 patients (average age of 49.6 years) according to the technique described by Tatum (1986). The subantral sinus cavity was augmented using bovine apatite combined with venous blood. After an average healing phase of 6.8 months, trephine burrs were used to take 22 bone biopsies from the augmented sinus region. Then 38 Branemark(R) implants were inserted in both the osteotomies resulting from bone sampling and in regular sites in the augmented posterior maxilla. Histomorphometric analysis of ground sections from the bone biopsies prepared according to the standard method of Donath & Breuner (1982) produced an average percentage of newly-formed bone of 14.7% (+/-5.0%) and a proportion of residual xenogenic bone substitute material of 29.7% (+/-7.8%). Some 29.1% (+/-8.1%) of the surface of the Bio-Oss(R) granulate was in direct contact with newly-formed bone. Histologically, newly-developed bone became evident, partly invaginating the particles of apatite and forming bridges in the form of trabeculae between the individual Bio-Oss(R) particles. Despite the absence of osteoclastic activity, the inward growth of bone indicates slow resorption of the xenogenic bone graft material. When the implants were uncovered, after an average healing phase of 6 months, 4 of the 38 implants had become loose. Of these 4 implants, 1 had to be subsequently explanted, while the others remained as “sleeping implants” and were not included in the implants superstructure.

Methods Medical records of Department of Oral and Maxillofacial Surgery of Shandong Provincial Hospital were screened for patients who had been treated with immediate implant implantation in the esthetic area using either MC (Allgens (R), Beijing Allgens Medical Science and Technology Co., Ltd., China) or Bio-Oss (Bio-Oss (R), Geistlich Biomaterials, Wolhusen, Switzerland), between January 2018 and December 2019. All patients fulfilling the in-/exclusion criteria and following followed for a minimum period of 1 year after surgery were enrolled into the presented study. Implant survival rate, radiographic, esthetic and patient satisfactory evaluations were performed. Results Altogether, 70 patients were included in the study; a total of 80 implants were inserted. All implants had good initial stability. The survival rate of implants was 100% at 1-year follow-up. The differences in horizontal and vertical bone loss between the MC group (0.72 +/- 0.26 mm, 1.62 +/- 0.84 mm) and the Bio-Oss group (0.70 +/- 0.52 mm, 1.57 +/- 0.88 mm) were no significant difference statistically no significant 6 months after permanent restoration. Similar results occurred at 12 months after permanent restoration functional loaded. Clinical acceptability defined by pink esthetic score (PES) >= 6 (6.07 +/- 1.62 vs. 6.13 +/- 1.41) was not significantly different between groups.

To assess this issue, this paper describes a real-time root cause analysis mechanism, which can pinpoint an accurate root cause and identify the influence on services. We investigated an interworking mechanism; based on a web service interface between an inventory and fault management systems and developed prototypes of them as part of an operation support system (OSS), which is capable of managing not only a core network and a metro ring network, but also a customer network. By introducing a hierarchical circuit model in the inventory management system and the proposed scanning algorithm over multiple layers and domains implemented in the fault management system, our developed root cause analysis was successfully verified using the testbed network environment; indicating relatively fast and scalable operation.","2009","2025-04-25 15:54:36","2025-04-25 15:54:36","","141-144","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IFIP; IEEE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Long-term follow-up of implants placed in BCP after sinus augmentation is still missing. Purpose: The primary aim of the study was to compare survival rates and marginal bone loss of Straumann SLActive implants placed in either BCP (test) or Bio-Oss (R) (DBB) (control) after sinus floor augmentation. The secondary aim was to calculate graft sinus height at different time points. Materials and Methods: Bilateral sinus floor augmentation was performed in a split mouth model. Eleven patients (mean age 67 years) received 100% BCP on one side and 100% DBB on the contralateral side. After 8 months of graft healing, 62 Straumann SLActive implants were placed. After 5 years of functional loading (6 years after augmentation) of implants, marginal bone levels and grafted sinus height were measured, and implant survival and success rates were calculated. Results: After 5 years of loading, all prosthetic constructions were in function although two implants were lost in each grafting material. The overall implant survival rate was 93.5% (91.7% for BCP, 91.3% for DBB, and 100% for residual bone). The success rates were 83.3% and 91.3% for BCP and DBB, respectively. There was no statistically significant difference in mean marginal bone level after 5 years between BCP (1.4 +/- 1.2 mm) and DBB (1.0 +/- 0.7 mm). Graft height reduction (GHR) after 6 years was limited to 6.6% for BCP and 5.8% for DBB. Conclusion: In this limited RCT study, the choice of biomaterial used for sinus floor augmentation did not seem to have any impact on survival rates and marginal bone level of the placed implants after 5 years of functional loading and GHR was minimal.","2016-10","2025-04-25 15:54:36","2025-04-25 15:54:36","","926-936","","5","18","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","biphasic calcium phosphate; bone substitutes; deproteinized bovine bone; sinus floor augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we evaluated biopsies of grafted bone with a mixture of autologous bone and Bio-Oss((R)) or BoneCeramic((R)) after two different healing time periods to understand the molecular process underlying bone formation after MSFE. Material and methodsSeven patients, following a bilateral split-mouth design model and needing a MSFE to allow implant placement, were recruited for this study. Right or left sinuses were grafted with autologous maxillary bone combined either with Bio-Oss((R)) or BoneCeramic((R)), respectively. Twenty biopsies were taken at the time of implant insertion after 4-5months or 6-8months of MSFE, and analyzed by micro-computed tomography (microCT) and gene-expression analysis. ResultsMicroCT analysis revealed no differences in the morphometric parameters or BMD either after 4-5months or 6-8months of MSFE between Bio-Oss((R)) and BoneCeramic((R)). At molecular level, a higher expression of bone forming gene Runx2 was observed after 4-5months of MSFE in the Bio-Oss((R)) compared with the BoneCeramic((R)) group. ConclusionsOur results indicate that differences found at the molecular level between Bio-Oss((R)) and BoneCeramic((R)) are not translated to important differences in the 3D microstructure and BMD of the grafted bone.","2015-06","2025-04-25 15:54:36","2025-04-25 15:54:36","","727-735","","6","26","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","bone graft; clinical study; dental implant; gene expression; maxillary sinus floor elevation (MSFE); micro-computed tomography (microCT)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, patient's perception of recovery and satisfaction with the surgical intervention are rarely reported. The objective of the present randomized controlled trial was to assess patient's perception of recovery after osteotome-mediated sinus floor elevation with Bio-Oss collagen compared with no grafting material. Forty healthy patients were randomly allocated to Bio-Oss collagen or no grafting material. Oral health-related quality of life was assessed by Oral Health Impact Profile-14 at enrollment. Patient's perception of recovery was assessed by self-administrated questionnaires and visual analog scale evaluating pain, social and working isolation, physical appearance, duration and quality of life alterations, eating and speaking ability, diet variations, and sleep impairment after 1 week and 1 month, respectively. Descriptive statistics was expressed as mean percentage with standard deviation. Correlation between impaired oral health-related quality of life, age, gender, and recovery were assessed by T test. Level of significance was 0.05. Results Osteotome-mediated sinus floor elevation is associated with high patient satisfaction, limited postoperative discomfort, and willingness to undergo similar surgery. Influence on patient's daily life activities seems to be minimal and limited to the first postoperative days. Most patients managed to return to work and their routine daily activities after 0-2 days. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery. However, number of days with pain, eating difficulties, and sleep disturbances were significantly increased with Bio-Oss collagen compared with no grafting material (P<0.05).

The LIG sensors are fabricated on polyimide (PI) Flexible Printed Circuit Board (FPCB) through CO2 infrared laser direct-write method. The LIG sensors provide repeatable high-precision temperature sensing, humidity measurement, and strain detection capability. The temperature sensing characterization shows the resistive LIG sensor has a sensitivity of -0.0493 %/degrees C, the linear fit R-square factors = 0.9973 across -40 degrees C to 125 degrees C. The capacitive humidity sensor achieves a normalized response of 2260% at 95% relative humidity (RH). Our proposed AFE chip contains a hybrid folded-cascode Operational Amplifier (OPAMP) with 92 dB gain and 12.5 MHz Gain Bandwidth Product (GBW), and a 14-bit 10 MHz Successive Approximation Register Analog-to-Digital Converter (SAR ADC). Designed using open-source analog flow and fabricated in GF180 OpenPDK, the AFE chip serves as a flexible and universal readout platform, adaptable for various sensing applications. A real-time demonstration of finger bending detection, with readings output by the AFE Chip, is performed to validate the system functionalities and robustness. The temperature, humidity, strain sensing capability provide by the wearable system are attractive for personal healthcare application.

PDLSCs and BMMSCs were obtained from the same canine donor. Twenty-four rats were randomly assigned to one of four experimental groups (n=6 each): group A (no-graft negative control), group B (Bio-Oss positive control), group C (BMMSC/Bio-Oss test group), and group D (PDLSC/Bio-Oss test group). Eight weeks post-transplantation, ectopic and in situ bone regeneration was evaluated by micro-computed tomography (mu-CT), histology, histomorphometry, and immunohistochemistry. The stem cell/Bio-Oss constructs were significantly superior to the controls in terms of their ability to promote osteogenesis (p<0.01), while the PDLSC/Bio-Oss construct tended to be superior to the BMMSC/Bio-Oss construct. Thus, engineered stem cell/Bio-Oss complexes can successfully reconstruct critical-size defects in rats, and PDLSCs and BMMSCs are both suitable as seed cells.","2014-08","2025-04-25 15:54:36","2025-04-25 15:54:36","","243-253","","2","29","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","Bio-Oss; bone marrow mesenchymal stem cell; Bone regeneration; comparative study; periodontal ligament stem cell; tissue-engineered bone","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the traditional powder materials were easy to agglomerate and settle, which led to the decrease of photocatalytic activity. The emergence of floating photocatalyst was important for the practical application of controlling harmful algal blooms. This study was based on the efficient powder photocatalyst bismuth oxide composite copper-metal organic framework (Bi2O3 @Cu-MOF), which was successfully loaded onto melamine sponge (MS) by sodium alginate immobilization to prepare a floating photocatalyst MS/Bi2O3 @Cu-MOF for the inactivation of Microcystis aeruginosa (M. aeruginosa) under visible light. When the capacity was 0.4 g (CA0.4), MS/Bi2O3 @Cu-MOF showed good photocatalytic activity, and the inactivation rate of M. aeruginosa reached 74.462% after 120 h. MS/Bi2O3 @Cu-MOF-CA0.4 showed a large specific surface area of 30.490 m2/g and an average pore size of 22.862 nm, belonging to mesoporous materials. After 120 h of treatment, the content of soluble protein in the MS/Bi2O3 @Cu-MOF-CA0.4 treatment group decreased to 0.365 mg/L, the content of chlorophyll a (chla) was 0.023 mg/L, the content of malondialdehyde (MDA) increased to 3.168 nmol/mgprot, and the contents of various antioxidant enzymes experienced drastic changes, first increasing and then decreasing. The photocatalytic process generated center dot OH and center dot O2-, which played key role in inactivating the algae cells. Additionally, the release of Cu2+ and adsorption of the material also contributed to the process.","2024-03-05","2025-04-25 15:54:36","2025-04-25 15:54:36","","","","","465","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Algae inactivation; Crosslinking reaction; Floating carrier; Microcystis aeruginosa; Photocatalysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We retrospectively collected data on advanced NSCLC not receiving a first-line platinum combination, focusing on clinical selection criteria. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor performance status. A single agent chemotherapy was offered with the prevalence of oral metronomic vinorelbine. In the whole population, progression-free survival and overall survival ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. Limited evidence is available concerning the selection criteria and the outcomes of platinum unfit newly diagnosed advanced NSCLC patients receiving single-agent chemotherapy. We retrospectively collected data on consecutive, stage IIIB-IV, EGFR/ALK negative and PD-L1 < 50% NSCLC patients treated with first-line single agent chemotherapy. Baseline characteristics, outcome measures and toxicities were recorded, as well as criteria according to which treatment selection was made and what percentage of patients did not receive a first-line platinum-based chemotherapy. Two-hundred and twenty-one patients were included. Median age was 79 (range 56-92) years, M/F 165(74.6%)/56(25.4%), ECOG performance status (PS) 0/1/ >= 2 23(10.9%)/94(42.5%)/103(46.6%), with a median of two serious comorbidities. A median of 25% (range 10%-30%) of newly diagnosed NSCLC did not receive a first-line platinum combination. Clinical criteria according to which decision was made were older age (76.5%), comorbidities (72%), poor PS (55.2%) and familiar or social issues (10%). Single-agent treatment consisted of oral metronomic vinorelbine (MetV 78.6%), gemcitabine (Gem 10%), oral standard vinorelbine (Vin 8.2%) and other (O 3.2%). Median progression-free survival (PFS) and overall survival (OS) of single agent treatments ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. All grade toxicities did not differ among single agents, while grade 3-4 toxicities were less frequent with MetV. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor PS. An oral treatment was frequently proposed with MetV being the most frequent choice according to its safety profile.","2022-12","2025-04-25 15:54:36","2025-04-25 15:54:36","","","","24","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","elderly; low performance status; metronomic; non-small cell lung cancer; single agent chemotherapy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, controversy exists regarding the need to cover the lateral osteotomy site with a membrane. Also, the healing period before loading remains undefined when machined-surface implants are placed. Twenty-nine patients showing reduced bone volume in the posterior maxilla had 61 Branemark System implants placed in 30 sinuses augmented with a lateral osteotomy approach. Sinuses grafted with Bio-Oss and covered with a collagen membrane Bio-Gide (M+) received 29 implants, while grafted but uncovered sites (M-) received 32 implants. An immediate procedure was followed to place 41 implants and a staged procedure was used for 20 implants, Abutment connection was made in 2 distinct postoperative periods: 6 to 9 months and over 9 months. The patients were followed for an average of 22.4 months. The survival rate of the implants was dependent on the postoperative healing time and membrane presence. In case of the immediate procedure and in M- sites, when residual bone height was less than 5 mm, more failures occurred when the loading was done at 6 to 9 months than after 9 months. No failures occurred in the M- series when a staged approach was followed. The overall survival rate was 78.1% for the M- sites and 93.1% for the M+ sites. No failures occurred (0/35) in the control implants placed in adjacent native bone. Implant survival rate was related to the quality of the reconstructed cortical plate and to implant length. The concomitant use of a collagen barrier to cover the osteotomy site, when machined-surface implants were used in sinus grafting, seemed to improve the quality of the graft healing and survival rate of the implants loaded between 6 and 9 months after placement.","2001-10","2025-04-25 15:54:36","2025-04-25 15:54:36","","713-721","","5","16","","","","","","","","","","English","","","","","","","Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC Type: Article","","","","bone grafting; endosseous dental implants; maxillary sinus; membranes","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study investigated mechanical strength in support of histological findings, specifically for tissue-engineered bone with mesenchymal stem cells (MSCs) and platelet-rich-plasma (PRP). Initially, teeth were extracted, and bone defects on both sides of the mandible were prepared with a trephine bar. The defects were implanted by using the following graft materials: 1) PRP, 2) PRP and dog MSCs (dMSCs), 3) autogenous bone (PCBM), 4) bone substitute (Bio-Oss (R)), and 5) control (defects only). After 2, 4, 8, and 12 weeks of implantation, the defects were histologically assessed to examine their mechanical properties. According to histological observations, the dMSCs/PRP groups had well-formed mature bone compared with the control (defects only), Bio-Oss (R), and PRP groups. The Vickers hardness test values were 8 (control), 9 (PRP), not detected (Bio-Oss (R)), 11 (PCBM), and 17 (dMSCs/PRP) after 2 weeks. Therefore, tissue-engineered bone can be used for early stage bone regeneration from the viewpoint of histology and mechanical properties.

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors ('problem solvers') tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs ('problems') tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between 'core' and 'peripheral' members identified exclusively on the basis of their individual level of contribution to the project.

Through an ethnographic approach to vital experiences of women in the Indian collective Linux-Chix, and holding a dialog with the experiences of non-organized women in the free software community in Colombia, this paper suggests these negotiations are going to be materialized primarily in the constitution of survival strategies from which certain civilizing projects are particularly vindicated, some of which seem to promote a Western paradigm of female subjectivity.

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making 'good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.

While some technologies are inherently political, other technologies become politicized through competition among different groups and organizations. How do seemingly apolitical technologies become politicized? In this article, the author examines the case of the ""circuit riders,"" a progressive technology movement in the United States that promotes information technology use among nonprofit and grassroots organizations, to show how a particular technology is politicized through field-level interactions. Applying and contributing to actor-network theory, the author finds that translation takes place as an organizational process by which actors associate the ideals of the technology in question with their political ideals and then attempt to enroll other actors to accept the resultant associations. Successful association depends on both discursive and organizational practices.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

In the project, we will use both quantitative and qualitative metrics to evaluate the health of OSS projects. The quantitative metrics will be gathered through automated crawling of meta information such as the number of contributors, commits and lines of code. Qualitative metrics will be gathered for selected “critical” projects through manual analysis and automated tools, including aspects such as sustainability, funding, community engagement and adherence to security policies. The results of the analysis will be presented on a user-friendly web platform, which will allow users to view the health of individual OSS projects as well as the overall health of the OSS ecosystem. With this approach, the CrOSSD project provides a comprehensive and up-to-date view of the health of OSS projects, making it easier for developers, maintainers and other stakeholders to understand the health of OSS projects and make informed decisions about their use and maintenance.","2023","2025-04-25 15:56:17","2025-04-25 15:56:17","","156–159","","","","","","","WWW '23 Companion","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Austin, TX, USA","","","","software security; open-source software; open-source health; quality monitoring","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context. We conclude by discussing governance issues related to the disciplined use and reuse of open source and areas for further improvements.","2022","2025-04-25 15:56:17","2025-04-25 15:56:17","","154–163","","","","","","","SPLC '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Graz, Austria","","","","open source software; dependencies; NPM; DevSecOps; maven","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For the OSS projects to stay sustainable, i.e., viable and maintained over time without interruption or weakening, maintenance labor requires an underlying infrastructure to be supported and secured. Aims: Using the construct of human infrastructure, our study aims to investigate how maintenance labor can be supported and secured to enable the creation and maintenance of sustainable OSS projects, viewed from the maintainers’ perspective. Method: In our exploration, we interviewed ten maintainers from nine well-adopted OSS projects. We coded the data in two steps using investigator-triangulation. Results: We constructed a framework of infrastructure design that provide insight for OSS projects in the design of their human infrastructure. The framework specifically highlight the importance of human factors, e.g., securing a work-life balance and proactively managing social pressure, toxicity, and diversity. We also note both differences and overlaps in how the infrastructure needs to support and secure maintenance labor from maintainers and the wider OSS community, respectively. Funding is specifically highlighted as an important enabler for both types of resources. Conclusions: The study contributes to the qualitative understanding of the importance, sensitivity, and risk for depletion of the maintenance labor required to build and maintain healthy OSS projects. Human infrastructure is pivotal in ensuring that maintenance labor is sustainable, and by extension the OSS projects on which we all depend.","2024","2025-04-25 15:56:17","2025-04-25 15:56:17","","37–48","","","","","","","ESEM '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Barcelona, Spain","","","","Open Source Software; Human Factors; Sustainability; Community Health; Maintainers; Project Health","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Stability requirements may necessitate fewer changes, compatible modifications, or security checks. Consequently, we conducted an analysis of 37,460 backports from 223,602 pull requests in open-source GitHub projects, aiming to identify types of incompatibilities encountered in real-life scenarios. We manually pinpointed various reasons why pull requests may lack compatibility with other versions, including contextual differences, varying dependencies, and statement-level alterations. This study constitutes the inaugural comprehensive characterization of changesets during the porting process across different versions with incompatibilities. The acquired insights can serve as a foundation for automated slicing and adaptation of changesets in stable software versions.","2024","2025-04-25 15:56:17","2025-04-25 15:56:17","","296–297","","","","","","","ICSE-Companion '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Lisbon, Portugal","","","","github; backport; commit; porting; pull-request","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., ""good first issues""), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained.

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.","2023","2025-04-25 15:56:18","2025-04-25 15:56:18","","180–190","","","","","","","dg.o '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Gda?sk, Poland","","","","GitHub; open source software; government; barriers; benefits; citizen engagement; evidence","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-25 15:56:18","2025-04-25 15:56:18","","3","","","","","","","ESEC/FSE 2019","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Tallinn, Estonia","","","","Software Ecosystems; Empirical Software Engineering; Software Measurement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project’s capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of sub-topics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project’s overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.","2022","2025-04-25 15:56:18","2025-04-25 15:56:18","","","","","","","","","OpenSym '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Madrid, Spain","","","","Health; Open Source Software; Sustainability; Software Ecosystem; Software Quality.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process.It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market.In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-04-25 15:56:18","2025-04-25 15:56:18","","1073–1083","","","","","","","ICSE '19","","","","IEEE Press","","","","","","","","","Place: Montreal, Quebec, Canada","","","","open source; motivation; code review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result. Our results suggest that there is no representative difference between their build success (they are similar in 85% of the analyzed projects), meaning that being a casual contributor is not a strong indicator for creating failing builds.

These communities' survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSS coach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process. However, there is also some indication that FLOSS coach did not lower the technical barriers.","2015","2025-04-25 15:56:18","2025-04-25 15:56:18","","160–169","","","","","","","SBES '15","","","","IEEE Computer Society","USA","","","","","","","","","","","","open source; newcomers; onboarding; contribution barriers; self-efficacy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In addition, we measured their self-efficacy before and after their participation. We found that what drove participants were intrinsic motivations, altruism, and internal values, which differed from previous work with older adults and with the general FOSS population. We also found that self-efficacy did not change significantly, even when participants encountered significant barriers or setbacks. The top 3 barriers were lack of communication, installation issues, and documentation issues. We found that asking for and receiving help, and avoiding difficult development environments were more likely to lead to success.

Objective: The goal of this research is to test Eric Raymond's assertions with respect to OSS success factors. Method: We present four criteria by which to assess project reflexivity in SourceForge. These criteria are based on three specific indicators: intended audiences, relevant topics, and supported operating systems. Results: We show in this short paper that 68% of SourceForge projects are likely reflexive (in the sense described by Raymond). Further, 76% of projects exceeding one million downloads are reflexive, 79% for projects exceeding ten million downloads, and 89% for projects exceeding one hundred million downloads. Conclusion: These results tentatively support Raymond's assertions that 1) OSS projects tend to be reflexive and 2) reflexive OSS projects tend to be more successful than irreflexive projects.

In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes.

This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software.

We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., Conceptual) and solution domain (i.e., Design) models. The results reveal a high correlation between the number of conceptual classes in the problem domain model and the number of software classes constituting the corresponding software. The results suggest that it is possible to use problem domain descriptions in the early stages of software development projects to make plausible predictions for the size of the software.","2014","2025-04-25 15:56:19","2025-04-25 15:56:19","","81–84","","","","","","","SEAA '14","","","","IEEE Computer Society","USA","","","","","","","","","","","","conceptual models; linear regression model for size estimation; size estimation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review, (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects, (iii) 24 responses to a questionnaire sent to 9 OSS projects, and (iv) semi-structured interviews with 36 sub-jects from 14 different projects, including newcomers and experi-enced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practi-tioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteris-tics, reception issues, orientation, technical hurdles, and docu-mentation problems. We could observe recurrent barriers evi-denced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-25 15:56:19","2025-04-25 15:56:19","","51–60","","","","","","","ARES '14","","","","IEEE Computer Society","USA","","","","","","","","","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To understand how this first contact influences future interactions, we studied eight mailing lists across four FOSS projects: MediaWiki, GIMP, PostgreSQL, and Subversion. We analyzed discussions initiated by newbies to determine the effect of gender, nationality, politeness, helpfulness and timeliness of response. We found that nearly 80% of newbie posts received replies, and that receiving timely responses, especially within 48 hours, was positively correlated with future participation.

Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world. OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization’s success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems.

Second, the business's social mission is not incidental but is furthered through its for-profit activities, rather than supported by the company's profits.

Second, the equilibrium market structure is influenced by both users' expertise and network effects. It is not surprising that proprietary software can drive OSS out of the market in presence of network effect, but counter-intuitively, this happens when users are highly skilled in OSS.

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization that naturally fix them during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-25 15:57:36","2025-04-25 15:57:36","","97–106","","","","","","","DSN '00","","","","IEEE Computer Society","USA","","","","","","","","","","","","Software; Faults; Heisenbugs; Recovery; Transient","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper then explores each phase of the lifecycle model and agrees that, while the bazaar phase attracts the most attention, it is the initial modular design that accommodates diverse interventions.

Structural complexity, an architectural concern, makes software projects more difficult to understand, and consequently more difficult to maintain and evolve. The contributors in a free software project exhibit different levels of participation in the project, and can be categorized as core and peripheral developers. Research aim: This research aims at characterising the changes made to the source code of 7 web server projects written in C with respect to the amount of structural complexity added or removed and the developer level of participation. Method: We performed a observational study with historical data collected from the version control repositories of those projects, recording structural complexity information for each change as well as identifying each change as performed by a core or a peripheral developer. Results and conclusions: We have found that core developers introduce less structural complexity than peripheral developers in general, and that in the case of complexity-reducing activities, core developers remove more structural complexity than peripheral developers. These results demonstrate the importance of having a stable and healthy core team to the sustainability of free software projects.","2010","2025-04-25 15:57:37","2025-04-25 15:57:37","","21–29","","","","","","","SBES '10","","","","IEEE Computer Society","USA","","","","","","","","","","","","FLOSS; Free Software; Open Source software; Empirical Software Engineering; Core and Periphery; Structural Complexity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs). The ReACTs are practical advice with specific steps, found in prior work to associate with tangible results. Starting from a set of sustainability-related features, this study contributes 105 ReACTs to the SE community by analyzing 186 published articles. Moreover, this study introduces a newly developed tool (ReACTive) designed to enhance the exploration of ReACTs through visualization across various facets of the OSS ecosystem.

We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

The primary difficulty is that software development efforts are complex in terms of both the technical and social aspects of the engineering environment. This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data. For four of the five project success measures, the results indicate that the developed model represents the underlying data well and provides accurate predictions of open source project success indicators.","2009","2025-04-25 15:57:37","2025-04-25 15:57:37","","","","","","","","","PROMISE '09","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Vancouver, British Columbia, Canada","","","","software engineering; FLOSS; agent-based simulation; Bayesian belief networks; data-based models","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Companies get involved in FLOSS projects to acquire user innovations [3, 12], to reduce costs [8, 11], to make money on complementary services [13], etc. Such intense involvement may change the nature of FLOSS development and pose critical challenges for the sustainability of the projects. For example, it has been found that a company's full control and intense involvement is associated with a decrease of volunteer inflow [13]. Sometimes a project may fail after one company pulls resources from the project [13]. This raises concerns about the domination of one company in a project. In large projects like OpenStack, there are often hundreds of companies involved in contributing code. Despite substantial researches on commercial participation, whether or not one company dominates a project and the impact of such domination has never been explicitly explored. We investigate four main projects of OpenStack, a large ecosystem that has had a tremendous impact on computing and society, to answer the following research questions: Does one company dominate the project's development (RQ1)?

Recent research has linked these problems to the values of Lyapunov exponents for the forward-dynamics, which describe the growth or shrinkage of infinitesimal perturbations. Here, we propose gradient flossing, a novel approach to tackling gradient instability by pushing Lyapunov exponents of the forward dynamics toward zero during learning. We achieve this by regularizing Lyapunov exponents through backpropagation using differentiable linear algebra. This enables us to ""floss"" the gradients, stabilizing them and thus improving network training. We demonstrate that gradient flossing controls not only the gradient norm but also the condition number of the long-term Jacobian, facilitating multidimensional error feedback propagation. We find that applying gradient flossing prior to training enhances both the success rate and convergence speed for tasks involving long time horizons. For challenging tasks, we show that gradient flossing during training can further increase the time horizon that can be bridged by backpropagation through time. Moreover, we demonstrate the effectiveness of our approach on various RNN architectures and tasks of variable temporal complexity. Additionally, we provide a simple implementation of our gradient flossing algorithm that can be used in practice. Our results indicate that gradient flossing via regularizing Lyapunov exponents can significantly enhance the effectiveness of RNN training and mitigate the exploding and vanishing gradients problem.","2023","2025-04-25 15:57:37","2025-04-25 15:57:37","","","","","","","","","NIPS '23","","","","Curran Associates Inc.","Red Hook, NY, USA","","","","","","","","event-place: New Orleans, LA, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level.In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-25 15:57:37","2025-04-25 15:57:37","","2366–2380","","","","","","","CCS '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Copenhagen, Denmark","","","","patch backporting; patch semantics; patch type","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions’ adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75% of the projects.

Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer. Our findings underscore the importance of a balanced approach in OSS project management, harmonizing productivity goals with resilience considerations.","2024","2025-04-25 15:57:38","2025-04-25 15:57:38","","706–709","","","","","","","WWW '24","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Singapore, Singapore","","","","causal inference; resilience; online collaboration networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

RecGFI models an issue with features from multiple dimensions (content, background, and dynamics) and uses an XGBoost classifier to generate its probability of being a GFI. To evaluate RecGFI, we collect 53,510 resolved issues among 100 GitHub projects and carefully restore their historical states to build ground truth datasets. Our evaluation shows that RecGFI can achieve up to 0.853 AUC in the ground truth dataset and outperforms alternative models. Our interpretable analysis of the trained model further reveals interesting observations about GFI characteristics. Finally, we report latest issues (without GFI-signaling labels but recommended as GFI by our approach) to project maintainers among which 16 are confirmed as real GFIs and five have been resolved by a newcomer.","2022","2025-04-25 15:57:38","2025-04-25 15:57:38","","1830–1842","","","","","","","ICSE '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","event-place: Pittsburgh, Pennsylvania","","","","open-source software; onboarding; good first issues","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Owing to the unrestricted access to source code, version control information, and bug tracking database, a comprehensive study on the Development Process associated with an OSS project is feasible. In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.","2025-03","2025-04-25 16:39:57","2025-04-25 16:39:57","","4","","1","33","","","","","","","","","","English","","","ABI/INFORM Global","3145911815","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Quality+enhancement+in+OSS+development+process%3A+a+quantitative+framework+approach&rft.au=.&rft.aulast=&rft.aufirst=&rft.date=2025-03-01&rft.volume=33&rft.issue=1&rft.spage=4&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-024-09705-0","Open source software; GitHub; Software quality; Resource allocation; Computers--Software; Source code; Decision analysis; Comparative analysis; Quality assessment; Operations research; Quantitative analysis; Multiple criteria decision making; Development process; Multi-criteria decision analysis; Multiple criterion; Project feasibility; Version control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This practice often renders the product superior to more centralized models such as those used in commercial software companies. How is such a phenomenon possible in a time where nothing seems to be acquirable save by purchase? Niels C. TAUBERT's book Productive Anarchy? Networks of Open Source Software Development aims at a sociological understanding of the prerequisites and conditions for the success of open source software. One of the conclusions of TAUBERT's book is that the process of open software development needs to be understood as adaptive and experimental. A continuous feedback between the context of production and the context of application is the basis for robust and successful software production. One of the surprising results of the book is that the most important requirement for this feedback process is a set of norms--neutrality, communism, disinterestedness, and universalism--norms that Robert MERTON associated with academic science in the 1940s. If TAUBERT is right that these norms are to be found outside the world of institutional science in open source software development projects today, then his case study can be seen as an indicator for a new form of knowledge production in the 21st century, where the social relevance and responsibility of a research process are keys to successful innovation. With this book, which deserves a wide readership, TAUBERT makes an important contribution to our understanding of the successful organization of technology development.

Usability is a clear concept that encompassing both task and user characteristics as well as functionality. Usability is an essential factor that affects user acceptance and OSS sustainability, which is considered as the key to the success of the OSS. To some extent, usability is one concern of the larger issue of system acceptability and sustainability. Therefore, usability is an important factor that needs to be considered since the software that is not usable is not going to be sustainable. The objective of this paper is to review researchers' efforts to improve, investigate, and evaluate the usability factor that may affect the OSS acceptability and sustainability and map the research scenery from the articles into a comprehensible structured taxonomy, which would help the researchers to identify different research gaps of this field. A survey of the usability in OSS conducted and 6033 studies identified by a search in four scholarly databases using a query that includes the keywords (usability or learnability or efficiency or satisfaction) and (open source software or OSS). A total of 46 studies are selected. By manually searching in ACM, Springer, and Google Scholar five other studies identified, and thus a total of 51 studies were the final set that includes in this paper. Based on research topics, a taxonomy created and divided into four principal categories which improve OSS usability, analyze OSS usability, evaluate OSS usability, and select and adopt OSS. A comprehensive overview and synthesis of these categories are presented as well. This paper contributes to identifying the possible opportunities and gaps for enabling the participation of interested researchers in this research area. And give possibilities for extending the use of usability research and practices to create more sustainable software. Also, helps in selecting suitable OSS among the alternatives.","2019","2025-04-25 16:48:48","2025-04-25 16:48:48","","65913-65933","","","7","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","open source software; sustainability; Usability; satisfaction; efficiency; learnability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Information, communication and information technology have made developing business becomes very competitive. It is very crucial for companies to have fast and accurate access to mission-critical business information in order to maintain its competitiveness. The ability to establish network connections between the existing systems becomes a must in order to optimize the use of critical information. To realize this, the implementation of system integration looks promising. However, system integration process is not an easy task because it involves variety of systems with different organizations backgrounds. The main objective of this paper is to propose an integration model that is generic and easily adapted by many organizations. The Information Management Division, Public Sector Department in Malaysia is chosen as a case study. The systems used in this department will be analyzed and problems faced will be identified. Research methodology conducted includes the Analysis Phase, Design Phase, Development Phase and Testing Phase. In order to support the proposed model, prototype called myIntegration is implemented based on OpenSyncro. OpenSyncro is an open source software (OSS) meant for Enterprise Application Integration (EAI). The Testing Phase was carried out by taking into account the actual test scenario involving the Department A (owner of the Malaysian Personal Record) and Department B (Human Resources Manager of Malaysian Civil Servants). Tests conducted have shown that the exchange of information between the Department A and B have been successfully realized. The finding from this research, where a new integration model has been created, can be referred by any government or private organizations in developing their systems integration facilities. The model also besides reducing the requirement of hardware; also reduces the dependency to proprietary products. In addition, the prototype developed, which based on OpenSyncro is capable in providing an alternative solution to the IT community to anchor any systems integration project at a lower cost and in a user friendly environment.","2011","2025-04-25 16:48:48","2025-04-25 16:48:48","","13-18","","","","","","","","","","","ACAD CONFERENCES LTD","CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND","English","","","","","","","Type: Proceedings Paper","","","","open source software; Enterprise Application Integration (EAI); integration model; middleware solution; system integration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However empirical studies on modularity of OSS systems have resulted in confusing results. To account for underlying mechanisms of those confusing results, we systematically examine widely studied OSS projects. Based on our systematic review on technical and organizational structures, we suggest that organizational circumstances of OSS production are at least in a continuum of tightly-coupled and loosely- coupled organizational circumstances of production in which both geographically distributed volunteers and paid developers with organizational ties work together (albeit separately over time). Furthermore, organizational circumstances of OSS production appear to be dynamic, as firms move in and out of OSS production communities over time. In essence we argue that the reason for the confusing empirical results was a persistent assumption that organizational circumstances of OSS production are static or unitary; rather what matters is the organizational circumstances of production in any episode of contribution. This research agenda paper proposes future inquiries to develop a comprehensive picture of ecological shift in different levels of system modularity and organizational circumstances of OSS production over time and through episodes.","2014","2025-04-25 16:48:48","2025-04-25 16:48:48","","","","","","","","","","","","","ASSOC INFORMATION SYSTEMS","P.O.

Since then, European universities have been involved in the development of the so-called European Higher Education Area (EHEA), including the adoption of a system of easily readable and comparable degrees, the European co-operation in quality assurance, and the promotion of mobility and European dimension in higher education. In this framework, the use of Free Open Source Software (FOSS) could provide several advantages, related to both the freedom given to users and the strengths of its peer-to-peer development model. In fact, some of the most outstanding characteristics of the FOSS (free, democratic, sustainable and technologically competitive educational model, cooperative and competitive relationships,.) result to be coincident with the main aims of the European Higher Education Area. In this paper we describe the role that this Free Open Source Software could play in the University context, also providing some statistical evidence about FOSS penetration and its recent evolution. Furthermore, since the implementation of the new university degrees can be considered as a “break point”, we briefly describe our FOSS experiences at the University of Oviedo, involving Statistics and Econometrics.

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 16:48:48","2025-04-25 16:48:48","","194-244","","","49","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","Open Source Software; Software Ecosystems; Episodic Volunteering; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume - suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017-06","2025-04-25 16:48:49","2025-04-25 16:48:49","","43-66","","2","29","","","","","","","","","","English","","","","","","","Place: 701 E CHOCOLATE AVE, STE 200, HERSHEY, PA 17033-1240 USA Publisher: IGI GLOBAL Type: Article","","","","Open Source Software; Segmented Regression; Developer Limit; Quality Control; Quality Control Index; Regression Discontinuity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the existing literature implicitly takes a static view that software structure and organizational structure are established early on and change slowly over time, if at all. Such a view does not fully reflect the complex and dynamic nature of software development and tends to overlook the role played by human agents as they ramp involvement up and down over time. This study considers that coordination practice plays an important role in altering technical interdependencies in OSS development. This study investigates coordination practices that result in changes in software coupling-in particular, increases in software coupling. This study automatically analyzes the code in 72 software releases and 1033 task episodes of three successful OSS projects-GNU grep, IPython, and Scikit-image. This study takes a fine-grained practice-oriented perspective that views the way that the work is done as constituting the organization. In our conceptualization, OSS contributors use a configuration of multiple organizational elements, enacted and varying across specific episodes of practice. In line with this perspective, this study takes a configurational approach, uses fuzzy-set qualitative comparative analysis (fsQCA) to analyze episodes that led to decreases, no changes, and increases in software coupling during the inter-release periods in which the level of software coupling increased significantly, which we call focal period. We find that co-work involving multiple individuals tends to result in code that adds technical dependencies (increases in software coupling) during the focal period. To illustrate this beyond our fuzzy-set analysis, we present and discuss three episodes in narrative detail. The fine-grained, configurational analysis in this study supports the idea that the organizing process is ongoing enactment. In this study, OSS systems are an amalgam of code that builds up in different episodes each possibly different organizational configurations, rather than thinking of the OSS systems or projects as static or singular.","2024-03","2025-04-25 16:48:49","2025-04-25 16:48:49","","","","1","34","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Online communities; Modularity; Configuration; Coupling; Open sources software; Organizing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An Examination of Open-Source Software Development by Organizations and Individuals","INFORMATION SYSTEMS RESEARCH","","1047-7047","10.1287/isre.2018.0829","","Collaboration through open superposition describes the dominant work orchestration mechanism observed in free (Libre) and open-source (FLOSS) software, wherein the software development occurs by the sequential layering of individual tasks. This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 16:48:49","2025-04-25 16:48:49","","764-786","","3","30","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","collaboration; motivation; econometrics; virtual teams; open-source software; information systems (IS) development; project success; superposition; task structure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using Cot its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

In this study, we argue that fit between the individual's task, values and work demands can influence or hinder the sustained use of OSS. We explore how task-technology fit and two dimensions of person-organization fit (value-based fit and demand-ability fit) interact with each other to influence productivity performance.

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project's time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project's progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.","2015-06","2025-04-25 16:48:49","2025-04-25 16:48:49","","1-23","","2","7","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","FLOSS; OSS; Open source project; survival; OSS popularity; hazard; ordinal regression; OSS success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust -> CCBs relationship.

To test the relationships hypothesized, we gathered data from 1409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

Survivability, critical for maintaining project quality and trustworthiness, is closely linked to issue activity, as unresolved issues reflect a decline in maintenance capacity and problem-solving ability. Thus, analyzing issue retention rates provides valuable insights into a project's health. This study evaluates OSS survivability by identifying the features that influence issue activity and analyzing their relationships with survivability. Kaplan-Meier survival analysis is employed to quantify issue activity and visualize trends in unresolved issue rates, providing a measure of project maintenance dynamics. A random forest model is used to examine the relationships between project features-such as popularity metrics, community engagement, code complexity, and project age-and issue retention rates. The results show that stars significantly reduce issue retention rates, with rates dropping from 0.62 to 0.52 as stars increase to 4000, while larger codebases, higher cyclomatic complexity, and older project age are associated with unresolved issue rates, rising by up to 15%. Forks also have a nonlinear impact, initially stabilizing retention rates but increasing unresolved issues as contributions became unmanageable. By identifying these critical factors and quantifying their impacts, this research offers actionable insights for OSS project managers to enhance project survivability and address key maintenance challenges, ensuring sustainable long-term success.","2025-01","2025-04-25 16:48:49","2025-04-25 16:48:49","","","","2","15","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open source software; software maintenance; survivability; Kaplan-Meier survival function; random forest","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

System changes are often done without considering their effects on the system structure. These changes often introduce structural anomalies between the concrete (as-built) and the conceptual (as-designed) architecture which can impede program understanding. The problem of architectural drift is especially pronounced in open source systems, where many developers work in isolation on distinct features with little co-ordination.

-"PHQEW3P6","journalArticle","2001","McGowan, D","Legal implications of open-source software","UNIVERSITY OF ILLINOIS LAW REVIEW","","0276-9948","","","The proliferation of computer technology and the advent of the Internet have created many new relationships and problems that raise questions about traditional legal and economic principles. The development of “open-source” or “free” software is an example of this phenomenon. Unlike the traditional producers of computer software - Microsoft for example - open-source software is often developed by computer programmers from all over the world, each submitting contributions to the code, and distributed without charge or for a minimal fee. Open-source software is generally passed from programmer to programmer, with the understanding that improvements may be made, but that the improvements must be distributed freely, without any attempt to “privatize” the program. The existence of such relationships among programmers raise several interesting questions. First, how do large-scale open-source projects come into being? One open-source project, the GNU/Linux operating system, even threatens the market share of Microsoft's operating systems - a feat that calls traditional economic theories on the operation of the firm into question. A more important question is whether the open-source model is sustainable and generalizable. Ultimately, one wonders what role the law will play in the open-source community - a community that seems to operate in the absence of traditional legal principles. In this article, which was introduced at the University of Illinois College of Law Symposium on Intellectual Property Challenges in the Next Century, Professor McGowan addresses these questions. Using the GNU/Linux operating system as a case study, he probes the organization of the open-source community and the philosophies of its leading members in order to understand how traditional firm models, intellectual property, and contract law might apply. Professor McCowan concludes by reviewing recent attempts by courts to impose traditional principles in computer software transaction disputes. Ultimately, it appears that the open-source community cannot be neatly categorized. Although many traditional firm theories - such as the formation of a hierarchy - and legal principles - such as copyright - do apply to the open-source model, these theories and principles are employed in creative ways not previously envisioned.","2001","2025-04-25 16:48:50","2025-04-25 16:48:50","","241-304","","1","","","","","","","","","","","English","","","","","","","Place: COLLEGE OF LAW-76 LAW BLDG 504 E PENNSYLVANIA AVE, CHAMPAIGN, IL 61820 USA Publisher: UNIV ILLINOIS Type: Article; Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, if OSS have few contributors and are lacking in maintenance activities, such as bug fixes, are used, it can lead to significant costs and resource allocation due to maintenance discontinuation. Since OSS are developed by a diverse group of contributors, the consistency of their involvement may vary, making continuous support and maintenance unpredictable. Therefore, it is necessary to identify the status of each OSS to avoid increased maintenance costs when selecting OSS for use. To address these issues, we use polynomial regression to predict trends in bug-fixing activities and evaluate the survivability of OSS accordingly. We predict the trend of bug-fixing activities in OSS, using factors such as popularity, number of contributors, and code complexity. A lower trend value indicates more vigorous activity. In this paper, we conduct data collection and extraction, generating model, and model testing and evaluation to predict survivability using these data. After collecting data through various tools, the models of different degrees are generated using K-fold cross-validation. The model with the highest performance is selected based on the RMSE (Root Mean Squared Error) and RSE (Residual Standard Error). Then, the chosen model is employed to predict the survivability of OSS and compare it with actual outcomes. This method is experimented with on OSS used in the KakaoTalk commercial messenger app. As a result, several OSS are predicted to have low survivability, and among them, five are analyzed. It is observed that, in reality, activities such as delayed or discontinued release updates occurred. These findings can support OSS users in selecting OSS for cost-saving purposes and alert OSS administrators to the need for solutions to ensure project survival.","2024-04","2025-04-25 16:48:50","2025-04-25 16:48:50","","","","7","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","GitHub; open source software; software maintainability; polynomial regression; survivability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: “situated learning” (the process of acting knowledgeably and purposefully in the world) and “identity construction” (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.","2009","2025-04-25 16:48:50","2025-04-25 16:48:50","","9-50","","4","25","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article; Proceedings Paper","","","","legitimate peripheral participation; communities of practice; qualitative study; open source projects; open source software community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.","2009","2025-04-25 16:48:50","2025-04-25 16:48:50","","532-549","","3-4","109","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Internet; Social networks; Open systems; Consumer behaviour; User studies","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, for such analysis to be possible, we need good metrics of a project quality. This paper develops two such metrics, first one reflecting project's popularity, and the second one - the quality of support offered by team members to users. The first metric is based on the number of `stars' a project is given by other GitHub members, the second is obtained using survival analysis techniques applied to issues reported on the project by its users.

In this paper, we present the CrOSSD project, which aims to build a database of OSS projects and measure their current project “health” status. In the project, we will use both quantitative and qualitative metrics to evaluate the health of OSS projects. The quantitative metrics will be gathered through automated crawling of meta information such as the number of contributors, commits and lines of code. Qualitative metrics will be gathered for selected “critical” projects through manual analysis and automated tools, including aspects such as sustainability, funding, community engagement and adherence to security policies. The results of the analysis will be presented on a user-friendly web platform, which will allow users to view the health of individual OSS projects as well as the overall health of the OSS ecosystem. With this approach, the CrOSSD project provides a comprehensive and up-to-date view of the health of OSS projects, making it easier for developers, maintainers and other stakeholders to understand the health of OSS projects and make informed decisions about their use and maintenance.","2023","2025-04-25 16:48:50","2025-04-25 16:48:50","","156-159","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Amazon Science; Baidu; Megagon Labs; Zhipu AI; Google; Booking Com; eBay; Bloomberg Engn; Netflix; ACM SIGWEB; Univ Texas Austin, Sch Informat; Data World; Inst Fdn Machine Learning Type: Proceedings Paper","","","","software security; open-source software; open-source health; quality monitoring","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.","2013-08","2025-04-25 16:48:51","2025-04-25 16:48:51","","619-643","","4","44","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","Open Source Software; Social Networks; Decision-making; Experiential Learning; License Choice; Vicarious Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With dual licensing, a firm releases the same software product under both a traditional proprietary license and an open source one. We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of “going open source” and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.","2011-03","2025-04-25 16:48:51","2025-04-25 16:48:51","","22-38","","1","22","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open-source software; business models; game theory; learning by doing; principal/agent; programmer compensation; programmer incentives; signalling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Substantial research was done to investigate central projects such as Linux kernel but we have only a limited understanding of how the periphery of the larger OSS ecosystem is interconnected through technical dependencies, code sharing, and knowledge flows. We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-25 16:48:51","2025-04-25 16:48:51","","3","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Assoc Comp Machinery Special Interest Grp Software Engn Type: Proceedings Paper","","","","Software Ecosystems; Empirical Software Engineering; Software Measurement","","Dumas, M; Pfahl, D; Apel, S; Russo, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While open source software has similarly distributed decision making and involves code and information flows similar to those in ordinary supply chains, the actual networks necessary to quantify and communicate risks in software supply chains have not been constructed on large scale. This work proposes to close this gap by measuring dependency, code reuse, and knowledge flow networks in open source software. We have done preliminary work by developing suitable tools and methods that rely on public version control data to measure and comparing these networks for R language and emberjs packages. We propose ways to calculate the three networks for the entirety of public software, evaluate their accuracy, and to provide public infrastructure to build risk assessment and mitigation tools for various individual and organizational participants in open sources software. We hope that this infrastructure will contribute to more predictable experience with OSS and lead to its even wider adoption.","2018","2025-04-25 16:48:51","2025-04-25 16:48:51","","458-459","","","","","","","Proceedings of the IEEE-ACM International Conference on Software Engineering Companion","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; Microsoft Res ISSN: 2574-1926 Type: Proceedings Paper","","","","open source; software supply chain; knowledge flow; risk management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the highly distributed and dynamic nature of OSS development, it is often described in unitary, monolithic terms - an unfortunate situation which masks considerable variance across OSS development processes. Therefore we explore reasons for systematic variance in these processes so as to enable more effective OSS development practices. Drawing on theory of distributed cognition, we develop a language of cognitive translations, which occur within and across distributed social arrangements and structural conditions of sharing knowledge. This language provides micro-foundations for understanding how different modes of OSS development emerge. Through examining how generative characteristics of social and structural distributions in OSS shape distinct development pathways, we propose a theoretically derived typology explaining the characteristics, dynamics, and conditions for success of different modes of OSS development.","2014","2025-04-25 16:48:51","2025-04-25 16:48:51","","4568-4577","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Univ Hawaii, Shidler Coll Business; IEEE Comp Soc ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sample of open source projects includes all mature projects driven by the Eclipse Foundation as of February 2008. Three types of project diversity were used: i) organizational - measured by number of committers per organization per project, ii) contribution - measured by the number of commits made per organization per project, and iii) technical - measured by the number of commits made per given software file type. Success was measured by means of i) economic metrics, including the number of corporate adoptions and the number of jobs postings including the project name, and ii) development metrics, including the project popularity and the growth of the intensity of members' activity. The paper makes two main contributions. First, we contribute to the literature on open source software and diversity.

Comparing to traditional software engineering approach, we found this approach is absolutely reversed. Open source development and delivery occurs on Internet time. Developers are not confined to a geographic area. They work voluntarily on a project of their choice; they are not forced to join a particular project just because it needs more developers or the project has a high degree of urgency. Developers work for peer-recognition and self-satisfaction. In the open source community, each and every project has an equal priority. Software designed under open source is not released until the project owner thinks that the software has reached a functional stage. One of the success stories is the Linux operating system. Open Source software is always in an evolutionary stage: it never reaches a final stage. As new requirements emerge the software is enhanced by the user/developers. In this paper, we give an introduction to the insights of open source software development. We then elucidate the perceived benefits and point out the differences between open source and closed source software development approaches. At the end we propose a new model for open source software development.","2003","2025-04-25 16:48:52","2025-04-25 16:48:52","","136-143","","","","","","","","","","","INT INST INFORMATICS & SYSTEMICS","14269 LORD BARCLAY DR, ORLANDO, FL 32837 USA","English","","","","","","","Backup Publisher: Int Inst Informat & System Type: Proceedings Paper","","","","","","Callaos, N; Lesso, W; Schewe, KD; Atlam, E","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects. (C) 2013 Elsevier B.V.

Accordingly, various articles in the literature assess the quality and success of OSS, by using different quality attributes and metrics and different approaches. Though this variety can be considered as a positive indicator of research interest and maturation on one side, it creates a kind of jungle in defining and understanding the terms `quality' and `success' on the other side. Based on this challenge, in this study, we targeted a systematic mapping (SM) of the articles on quality and success of OSS. More than 474 articles have appeared in this area between the years 2002 and 2017, and the final pool of 128 articles is obtained by defining and applying inclusion and exclusion criteria. SM was employed to develop a classification scheme and categorized the existing body of articles with respect to five research questions (RQs) on: contribution and research types, quality criteria and metrics, success criteria and metrics, the relation of quality and success, and demographics. We observed that the majority of the articles assess the concept of quality as `code quality', whereas the concept of success is mostly perceived as `market success' and/or `developer activity'. Moreover, the metrics of `contributing developers/users', and the quality attribute of `functionality' are the quality criteria most employed in the assessment of success.","2019","2025-04-25 16:48:52","2025-04-25 16:48:52","","363-370","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","open source; OSS; software metrics; success; software; quality; systematic mapping","","Staron, M; Capilla, R; Skavhaug, A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (Von Hippel and Von Krogh, 2003, 2006), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that - (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described. (C) 2013 Elsevier B.V.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. Design/methodology/approach - The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. Findings - The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain. Last, but not least, it blurs the boundary between development and use, since the developer remains the key user. Research limitations/implications - The paper addresses the implications for future research in the area. Practical implications - The paper addresses implications for practitioners directly involved in innovation and product development. Originality/value - This paper develops a conceptual framework for understanding product development based on non-proprietary knowledge, which cannot be adequately accounted for by traditional corporate innovation theory alone.","2008","2025-04-25 16:48:52","2025-04-25 16:48:52","","142+","","1","11","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Innovation; Resource management; Communication technologies; Internet; Open systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lockin, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-04-25 16:48:52","2025-04-25 16:48:52","","7-12","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Collaborative development of open source software (OSS) has witnessed an exponential increase in two decades. Our hypothesis is that software ecosystems bear many similarities with natural ecosystems. While natural ecosystems have been the subject of study for many decades, research on software ecosystems is more recent. For this reason, the ECOS research project aims to determine whether and how selected ecological models and theories from natural ecosystems can be adapted and adopted to understand and better explain how OSS projects (akin to biological species) evolve, and to determine what are the main factors that drive the success or popularity of these projects. Expressed in biological terms, we wish to use knowledge on the evolution of natural ecosystems to provide support aiming to optimize the fitness of OSS projects, and to increase the resistance and resilience of OSS ecosystems.","2014","2025-04-25 16:48:53","2025-04-25 16:48:53","","403-406","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Fnrs; FWO; Univ Antwerpen; Reengineering Forum Type: Proceedings Paper","","","","","","Demeyer, S; Binkley, D; Ricca, F","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The traditional market failure argument suggests that innovation is characterized by high investment and low copy cost, and firms have difficulty in internalizing the fruits of their innovative effort. Thus, technology firms are seeking more patents, expanding their scope and overhauling their business models around intellectual property. Yet paradoxically, with the progress and development of information technology, open source software (OSS) plays an important role in expanding enterprise informatization. For example, Linux is developed quickly by this open way. Some firms have found the ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is one example. In this article, the author introduces a model of OSS based on its network effects to understand how the enterprises decide their activities in this open market competition. This article describes the inherent reasons of open source movement from the view of the oligopoly structure. At the same time, this article analyses the effect of leader enterprise and follower enterprise on market structure and the different activities of these enterprises after the source has been opened. Finally, we make suggestions that companies at the leading edge are often in such a strong position that they do need the support of down-streams companies to broaden their technologies successfully and to decrease their risks in order to leverage the value of the technological portfolio. On the other hand, this article suggests that follower enterprises have incentive to take part in the development of open-source software only when the market has grown up.","2008","2025-04-25 16:48:53","2025-04-25 16:48:53","","669+","","","254","","","","International Federation for Information Processing","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","ISSN: 1571-5736 Type: Proceedings Paper","","","","open source software; enterprise normalization; OSS model","","Xu, LD; Tjoa, AM; Chaudhry, SS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the method of evolution of the internal quality of object-oriented open-source software systems has been examined by applying a software metric approach. More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics. The results and observations of this research include: (i) there is a significant difference between different systems concerning the LOC variable (ii) there is a significant correlation between all pairwise comparisons of internal quality metrics, and (iii) the effect of complexity and inheritance on the LOC was positive and significant, while the effect of Coupling and Cohesion was not significant.","2021-06","2025-04-25 16:48:53","2025-04-25 16:48:53","","","","12","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","software evolution; software engineering; software metrics; internal quality; open-source software systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Over time, organizations face the OSS adoption challenge strengthening mainly its internal and technical elements. However, the rapid changes on business dynamics, and the comprehensiveness and fast development of open paradigms, show us that a new set of conditions must be satisfied to reach a successfully OSS adoption. These conditions, considered as a critical success factors, involve a wide range of resources, capacities and skills, both in internal and external scopes. Hence, although adopter organizations should be better prepared to face the challenges related to collaborative innovation, they do not have a systematic approach to value its readiness level to face the adoption challenges. In this context, the present research work proposes a model to assess the organizational readiness, considering the adopter as part of a live business ecosystem, where the relationships originated on co-development with developers' communities, have mutual business impact at strategic, tactic, and operative level.","2021","2025-04-25 16:48:53","2025-04-25 16:48:53","","800-807","","","","","","","","","","","SCITEPRESS","AV D MANUELL, 27A 2 ESQ, SETUBAL, 2910-595, PORTUGAL","English","","","","","","","Backup Publisher: INSTICC Type: Proceedings Paper","","","","Open Source Software Adoption; Open Innovation; Organizational Readiness Assessment","","Filipe, J; Smialek, M; Brodsky, A; Hammoudi, S","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey. Our findings indicate that cooperative norms and effective communication engender trust, whereas an accreditation mechanism eliminates distrust.

In this article we argue that disadvantage is more due to gendered behavior than to categorical discrimination: women are at a disadvantage because of what they do, rather than because of who they are. Using data on entire careers of users from GitHub.com, we develop a measure to capture the gendered pattern of behavior: We use a random forest prediction of being female (as opposed to being male) by behavioral choices in the level of activity, specialization in programming languages, and choice of partners. We test differences in success and survival along both categorical gender and the gendered pattern of behavior. We find that 84.5% of women's disadvantage (compared to men) in success and 34.8% of their disadvantage in survival are due to the female pattern of their behavior. Men are also disadvantaged along their interquartile range of the female pattern of their behavior, and users who don't reveal their gender suffer an even more drastic disadvantage in survival probability. Moreover, we do not see evidence for any reduction of these inequalities in time. Our findings are robust to noise in gender recognition, and to taking into account particular programming languages, or decision tree classes of gendered behavior. Our results suggest that fighting categorical gender discrimination will have a limited impact on gender inequalities in open source software development, and that gender hiding is not a viable strategy for women.","2019-07-06","2025-04-25 16:48:53","2025-04-25 16:48:53","","","","","8","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Open source; Software development; Gender inequality; Gendered behavior","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

However, newcomers face many barriers when making their first contribution, leading in many cases to dropouts. Due to the collaborative nature of community-based OSS projects, newcomers may be susceptible to social barriers, such as communication breakdowns and reception issues. In this article, we report a two-phase study aimed at better understanding social barriers faced by newcomers. In the first phase, we qualitatively analyzed the literature and data collected from practitioners to identify barriers that hinder newcomers' first contribution. We designed a model composed of 58 barriers, including 13 social barriers. In the second phase, based on the barriers model, we developed FLOSScoach, a portal to support newcomers making their first contribution. We evaluated the portal in a diary-based study and found that the portal guided the newcomers and reduced the need for communication. Our results provide insights for communities that want to support newcomers and lay a foundation for building better onboarding tools. The contributions of this paper include identifying and gathering empirical evidence of social barriers faced by newcomers; understanding how social barriers can be reduced or avoided by using a portal that organizes proper information for newcomers (FLOSScoach); presenting guidelines for communities and newcomers on how to reduce or avoid social barriers; and identifying new streams of research.","2019-04","2025-04-25 16:48:54","2025-04-25 16:48:54","","247-290","","1-2","28","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Joining; Newcomers; Onboarding; Open source software; Online communities; FLOSS; Socialization; Challenges; Difficulties; Beginners; Entry; New contributor; Newbies; Qualitative study; Social barriers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most of the educational organizations have already adopted smart learning environment by upgrading their infrastructure and with proper capacity building among staff members. But in the education sector, sustainability of technology is always being a challenge. To develop learning materials, many institutions have already started using free and open source software (FOSS) tools. FOSS gives freedom to the developer with the provision of various customization options as per the requirements of the class or subject. Moreover, in the longer run, free and open source software could be considered as the best option in education for e-learning implementation, for sustainability. There are many tools which are available for e-learning resource development. Some of them are available online and some are available as an installer for the various platform. In order to adapt ICT in education, especially in non-IT specialization, the faculty members need the training to learn and implement these tools in their classes. But there are many tools, which are specially designed for educators with basic knowledge of computers. Educators can plan their sessions, based on content, duration as well as the level of the subject and the students. This research paper will highlight various aspects of the implementation of FOSS, in education by using such easy-to-implement tools and techniques.

Communications and collaborations are essential for the success of projects. Usually, the most active and productive programmers are awarded with promotion to developers. To more effectively manage and progress the projects, it is important and beneficial to rank the programmers and thus, predict the developer candidates. In this work, we propose to combine machine learning techniques with existing complex network node ranking algorithms to improve the prediction results. Specifically, we have made the following contributions: (1), we have designed a novel machine learning-based classifier with significantly improved prediction performance; (2), we have constructed and tested various networks built based on the programmer email communication information; and (3), we have used real-world project data to compare different techniques and validate our methods. Experimental results demonstrate that our technique reduces the error rate by 25% compared with the second best. Moreover, we discover that the KK nearest neighbor (KNN)-based machine learning algorithm and non-directional temporal network with a time window of 1-3 months give the best prediction results.","2018-06","2025-04-25 16:48:54","2025-04-25 16:48:54","","845-868","","6","28","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","machine learning; Open source software; complex network; ranking algorithm","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A standard DSpace installation runs on a Tomcat servlet container. BIBSYS does not use this container, and we therefore needed to configure DSpace to get it to run successfully on our server. In addition we had some problems with integrating the DSpace development structure with our integrated development environment. Further we needed to create a new build process that effectively could build more than 30 applications from one source code. These changes were quite time consuming, but they were necessary so that we could have an efficient work environment. Out of the box DSpace has many of the functionalities that an institutional archive requires. In spite of this we needed to alter some of the functionality, especially the user management system. DSpace is a complex system, but with the active community we could get the help we needed. BIBSYS Brage, the result of the Pepia project, was launched as a beta version in December 2006. We look forward to develop BIBSYS Brage further, and are confidant that it will become a great system for the consortium.","2007-12","2025-04-25 16:48:54","2025-04-25 16:48:54","","","","19","","","","","","","","","","","English","","","","","","","Place: C ADOLF FLORENSA S-N, BARCELONA, 08028, SPAIN Publisher: UNIV BARCELONA, SERVEI PUBLICACIONS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The success of the OSS model is also setting the stage for a structural change in the software industry; it is beginning to transform software industry from manufacturing to a service industry. Despite the success of the OSS model, for-profit organizations are having difficulty building a business model around the open source paradigm. Whereas there are some isolated empirical studies, little rigorous research has been done on how traditional organizations can implement and benefit from OSS practices. This research explores how organizations can foster an environment similar to OSS to manage their software development efforts to reap its numerous advantages: Drawing on organizational theory, we develop a framework that guides the creation and management of a hybrid-OSS community within an organization. We discuss the implications of this framework and suggest areas for future research.","2002-01","2025-04-25 16:48:54","2025-04-25 16:48:54","","7-25","","1","12","","","","","","","","","","English","","","","","","","Place: 9600 GARSINGTON RD, OXFORD OX4 2DG, OXON, ENGLAND Publisher: BLACKWELL PUBLISHING LTD Type: Article","","","","software development; open source software; features of OSS; hybrid-OSS community; OSS framework","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To detect such vulnerabilities, finding OSS reuses in COTS software has become imperative. While scalable to tens of thousands of OSS projects, existing binary-to-source matching approaches are severely imprecise in analyzing COTS software products, since they support only a limited number of code features, compute matching scores only approximately in measuring OSS reuses, and neglect the code structures in OSS projects. We introduce a novel binary-to-source matching approach, called B2SFINDER1, to address these limitations. First of all, B2SFINDER can reason about seven kinds of code features that are traceable in both binary and source code. In order to compute matching scores precisely, B2SFINDER employs a weighted feature matching algorithm that combines three matching methods (for dealing with different code features) with two importance-weighting methods (for computing the weight of an instance of a code feature in a given COTS software application based on its specificity and occurrence frequency). Finally, B2SFINDER identifies different types of code reuses based on matching scores and code structures of OSS projects. We have implemented B2SFINDER using an optimized data structure. We have evaluated B2SFINDER using 21991 binaries from 1000 popular COTS software products and 2189 candidate OSS projects. Our experimental results show that B2SFINDER is not only precise but also scalable. Compared with the state of the art, B2SFINDER has successfully found up to 2.15x as many reuse cases in 53.85 seconds per binary file on average. We also discuss how B2SFINDER can be leveraged in detecting OSS reuse vulnerabilities in practice.","2019","2025-04-25 16:48:54","2025-04-25 16:48:54","","1038-1049","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Comp Soc Tech Council Software Engn; ACM Special Interest Grp Artificial Intelligence; ACM Special Interest Grp Software Engn Type: Proceedings Paper","","","","OSS; Code Reuse; Binary-to-Source Matching; Code Feature; COTS Software; One-Day Vulnerability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This process is reviewed and illustrated with OsiriX, a fast DICOM viewer program for the Apple Macintosh. Materials and methods OsiriX is an oss for the Apple Macintosh under Mac OS X v10.4 or higher specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: multiplanar reconstruction, surface rendering, volume rendering and maximum Intensity projection. All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT). OsiriX was developed using the Apple Xcode development environment and Cocoa framework as both a DICOM PACS workstation for medical imaging and an image processing software package for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging. Results OsiriX is an open source program by Antoine Rosset, a radiologist and software developer, was designed specifically for the needs of advanced imaging modalities. The software program turns an Apple Macintosh into a DICOM PACS workstation for medical imaging and image processing. OsiriX is distributed free of charge under the GNU General Public License and its source code is available to anyone. This system illustrates how open software development for medical imaging tools can be successfully designed, implemented and disseminated. Conclusion oss development can provide useful cost effective tools tailored to specific needs and clinical tasks. The integrity and quality assurance of open software developed by a community of users does not follow the traditional conformance and certification required for commercial medical software programs. However, open software can lead to innovative solutions designed by users better suited for specific tasks.","2006-12","2025-04-25 16:48:54","2025-04-25 16:48:54","","187-196","","4","1","","","","","","","","","","English","","","","","","","Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, it is important to establish the best software development and contributing practices early in the life-time of the project. Such practices should foster the contributors' involvement in the OSS project as quickly as possible. The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors' learning processes is an important research area in OSS. This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education. It is argued that collaboration with peers and consistent code contributions result in learning progress in OSS.

Compared to the Apache project, FreeBSD uses a smaller set of core developers that implement a smaller portion of the system, and uses a more well-defined testing process. FreeBSD and Apache have a similar ratio of core developers to (1) people involved in adapting and debugging the system, and (2) people who report problems.

Maintenance effort is usually measured in person-hours used to perform a maintenance task. However, maintenance effort data are usually only available for strictly managed software, such as closed-source software. In other software projects that do not have complete maintenance records, especially some open-source software, there are no direct data for maintenance effort, which precludes the establishment of a maintenance effort model. In this paper, we report a series of studies aimed at presenting a method for indirectly predicting the maintenance effort of open-source software. This report covers two parts of our research. First, we examine the maintenance data from NASA SEL closed-source software projects and identify some software measures that can be used to indirectly represent maintenance effort. Second, based on the findings in the first part, we analyze 121 recent versions of Linux, and use linear regression to construct two indirect maintenance effort models for the Linux project. Our study demonstrates the applicability of this approach to indirectly predicting the maintenance effort and improving the software maintenance process.

Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world! OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization's success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future.

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context. Can rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 16:48:55","2025-04-25 16:48:55","","1449-1469","","4","63","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","OSS; Open-source software; Entrepreneurship; Trust; Crowdfunding; L26; O30; O34; O36","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the discrete modeling framework has been proposed to study the reliability growth process of OSS systems with multiple releases. The proposed model is based upon the assumption that during up-gradation some new faults are introduced in the code in addition to the left over fault content of the previous version. To validate our model, we have chosen two successful open source projects-Mozilla and Apache for its multi release failure datasets. Graphs representing goodness of fit of the proposed model have been drawn. The parameter estimates and measures of goodness of fit criteria suggest that the proposed software reliability growth model for multi-release OSS fits the actual datasets very well. An optimal release policy has been formulated by taking into account the cost of fault removal during testing and operational phases and reliability targets pre-specified by the decision makers.

We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success.

Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

First we develop a requirements-based taxonomy of open-source projects and we discover patterns linking between this taxonomy and project success. We also propose a classification of requirement types based on their representativeness in open-source projects. This highlights the overall importance of various types of requirements in the context of open-source software development.

A preliminary study was done to explore the state of OSS implementation among government agencies since the launch of the Malaysian Public Sector OSS Master Plan on July 16, 2004. Semi-structured face-to-face interviews using open-ended questions were conducted with IT managers and IT officers in the Northern Region of Peninsular Malaysia. The preliminary study aimed at investigating the usage of OSS and proprietary software, the level of OSS utilisation, the level of OSS knowledge and training of ICT and non-ICT staff, software development and acquisition model, internal OSS manpower capabilities and skills, the user's perception of the advantages of OSS, the user's perception of the risks of OSS, and the problems or barriers in OSS implementation. The results of interviews show that there are many problems or barriers in OSS implementation, e.g. lack of internal OSS expertise, lack of OSS policy, and lack of top management support. Therefore, this study will test the hypotheses on the success factors to OSS implementation in the public sector and to propose a framework for successful OSS implementation in the Malaysian Public Sector. A quantitative approach using survey method via questionnaire will be performed to answer the research question where simple random sampling will be used.

These communities' survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSScoach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process. However, there is also some indication that FLOSScoach did not lower the technical barriers.","2015","2025-04-25 16:48:56","2025-04-25 16:48:56","","160-169","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: ThoughtWorks; AvenueCode; Google; take.net; RARO Labs; Avanti; IBM; CNPq; CAPES; FAPEMIG; UFmG; PUC Minas; CEFET MG Type: Proceedings Paper","","","","open source; newcomers; onboarding; contribution barriers; self-efficacy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Yet, newcomers face a steep learning curve during OSS onboarding in which they must overcome a multitude of technical, social, and knowledge barriers. To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., “good first issues”), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.","2023","2025-04-25 16:48:56","2025-04-25 16:48:56","","324-336","","","","","","","International Conference on Software Engineering-Software Engineering Education and Training","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISSN: 2832-756X Type: Proceedings Paper","","","","open source software; open source onboarding; software engineering education","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In spite of having these benefits, numerous challenges can be faced during the multi-release OSS development. Some of the challenges can be the generation of errors during the addition of new features. To address the changing fault detection process, a change point phenomenon is considered so as to give more practicality to the model.

Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities.

The culture and norms of FLOSS appear to be formulated by what is privileged/marginalized by men in the context of FLOSS, and such men's valuing is likely to threaten women FLOSS participants' face. Our findings are 1) in the FLOSS context, there are gender-based differences in determining what threatens face on the basis of gendered expectations of what is polite, and 2) women-dominated FLOSS participants are “practically” polite in software development practices.

Because students are accustomed to gathering information using commercial search engines, they can overlook high-quality library resources. To connect with student researchers when they need library resources, many libraries have built online research guides tied to specific subjects and courses. These guides can address specific assignments where research is required, and course instructors can point students to the guides to assist them in completing their research assignments successfully. In 2006, Oregon State University (OSU) Libraries developed an open source software product called Library a la Carte that librarians can use to construct research guides easily and quickly. The code was made available to other libraries, and a number of institutions have adopted the tool. A successful user community has grown up around Library a la Carte, but development up to this point has been the sole responsibility of OSU Libraries. We are now embarking on building a robust developer community, to contribute code, to build additional features and to take Library a la Carte into the future. As part of our plan to move forward, we are testing a hosted (cloud-based) version of the software.

Our difference-in-difference estimates show that in the months following the filing of SCO v. IBM, OSS projects that exhibit high technology overlap with the disputed OSS experienced a 15% greater decline in user interest and 45% less developer activity than projects in the control group; OSS projects that are intended for business and specific to the disputed OSS platform had a 34% greater decline in user interest and 86% less developer activity than the control group. We find similar results following the filing of FireStar/DataTern v. Red Hat. Our results are also robust to a variety of robustness checks, including a falsification exercise and subsample analyses.","2013-12","2025-04-25 16:48:56","2025-04-25 16:48:56","","1131-1146","","4","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software (OSS); OSS success; difference-in-difference estimation; intellectual property rights (IPR); intellectual property rights enforcement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper investigates the contribution of Free/Libre Open-Source Software (FLOSS) towards fair, and conflict-free practices through promoting collaboration, transparency, and resource accessibility. Our study investigates how the adoption of decentralized online social networks (DOSN) like Mastodon (microblogging) and PeerTube (video sharing), which operate on the ActivityPub protocol, contributes to sustainable practices within the electronics sector by fostering a federated universe (Fediverse). It is demonstrated how FLOSS, in the form of Alternative Mobile Operating Systems (AMOS) including Android open-source custom ROMs or mobile Linux systems, gain traction due to enhanced privacy protection, improved usability through tracker-free software and alternative app stores, and adherence to EU directives on the right to self-repair. As AMOS mature for everyday use, they attract consumers, thereby contributing towards sustainable electronics development. Furthermore, the Fediverse's Application Programming Interfaces (APIs) enable seamless information exchange between instances, allowing for nuanced moderation that safeguards user privacy. This approach contrasts with centralized commercial networks, where algorithm-driven operations often prioritize profit over user well-being.","2024","2025-04-25 16:48:57","2025-04-25 16:48:57","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","","","FLOSS; sustainability; Fediverse; alternative mobile operating systems (AMOS); decentralized","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite concerns that reviews may be ignored, or that discussions will deadlock because too many uninformed stakeholders are involved, we find that this approach works well in practice. In this paper, we describe an empirical study to investigate the mechanisms and behaviours that developers use to find code changes they are competent to review. We also explore how stakeholders interact with one another during the review process. We manually examine hundreds of reviews across five high profile OSS projects.

The results indicate that Carnegie classification is a critical differentiator of awareness, adoption, and perceptions of Open Source software applications, with perceived cost of ownership being the key driver of Open Source adoption. Moreover, the study shows that institutions have made little progress in the development of polices and procedures for Open Source regulatory compliance and security.

The overall success of peer code review, commonly used in open source projects, has likely contributed strongly to this success. Code review is an emotionally loaded practice, with public exposure of reputation and ample opportunities for conflict. We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process. It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market. In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-04-25 16:48:57","2025-04-25 16:48:57","","1073-1083","","","","","","","International Conference on Software Engineering","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE Comp Soc, Tech Comm Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","Motivation; Open Source; Code Review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study shows that open source software has certain facets; code, community, coordination mechanisms, license and documentation. Each facet is not stable; indeed, it is changing and mutable. This creates possibilities, potential but also recalcitrance, and barriers. The interesting point of departure of our study is how open source software a much touted transparent and open phenomenon is by its nuanced and layered mutability able to make the process and practices surrounding it less visible. It concludes with clear policy recommendations developing from this research that could help to make open source adoption more sustainable in the public sector. (c) 2015 Elsevier Inc.

National user groups can bolster these international communities by convening local events, championing the software to peers, welcoming and onboarding new contributors, raising money to support the broader community, and collecting important information on user's needs. The open source community-led software DSpace has had great success encouraging the creation of national user groups; in the UK, North America, and Germany, the Groups have been active for many years. However, it was in 2018, thanks to a renewed focus on international engagement and more diverse representation of the global community in governance groups, that the national communities entered into a new phase: 15 new national User Groups have been formed all over the world since then, while the German user group evolved into the “DSpace-Konsortium Deutschland”, founded by 25 institutions, marking a pivotal point for membership options and National User Group participation within DSpace Governance. This article will offer an overview of the historical development of the DSpace community and its governance model, as well as DuraSpace's international engagement strategy, including its benefits and challenges.

In GitHub, developers are allowed to fork repositories and copy repositories without asking for permission, which make contribution to projects much easier than it has ever been. It is significant to predict the number of forks for open source software projects. The prediction can help GitHub to recommend popular projects, and guide developers to find projects which are likely to succeed and worthy of their contribution. In this paper, we use stepwise regression and design a model to predict the number of forks for open source software projects. Then we collect datasets of 1,000 repositories through GitHub's APIs. We use datasets of 700 repositories to compute the weight of attributes and realize the model. Then we use other 300 repositories to verify the prediction accuracy of our model. Advantages of our model include: (1) Some attributes used in our model are new. This is because GitHub is different from traditional open source software platforms and has some new features. These new features are used to build our model. (2) Our model uses project information within t month after its creation, and predicts the number of forks in the month T (t < T). It allows users to set the combination of time parameters and satisfy their own needs. (3) Our model predicts the exact number of forks, rather than the range of the number of forks (4) Experiments show that our model has high prediction accuracy. For example, we use project information with 3 months to prediction the number of forks in month 6 after its creation. The correlation coefficient is as high as 0.992, and the median number of absolute difference between prediction value and actual value is only 1.8. It shows that the predicted number of forks is very close to the actual number of forks. Our model also has high prediction accuracy when we set other time parameters.","2014","2025-04-25 16:48:57","2025-04-25 16:48:57","","40-47","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Type: Proceedings Paper","","","","Open Source Software; Fork","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making `good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.","2009","2025-04-25 16:48:58","2025-04-25 16:48:58","","51-71","","1","74","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","ethics; Software; freedom; progress; social form","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are several ways to measure the quality of software systems. Mainly, measuring the ability of test cases to detect and find defects is used. This research focuses on finding a good technique to evaluate the effectiveness of test cases for finding defects in open source systems. Experiments are conducted on six OSS (open source software). The result shows how the effectiveness of test suite of could give an indication about studied systems quality.","2016","2025-04-25 16:48:58","2025-04-25 16:48:58","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Type: Proceedings Paper","","","","Software Quality; Error Seeding; Mutation Testing; Open Source Code; Test Coverage","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some countries have successfully created extensive information technology infrastructures, yet software use continues to be reliant on pirated sources. The experiences of licensing regulation violations and increasing virus attacks indicate that part of the problem is a consequence of dependencies created by the use of proprietary software within resourcescarce economies. Recent growth in the use of free and open-source software (FOSS) by various public-and private-sector agencies suggests an alternative path to software self-suffciency for a resource-scarce country like Cuba. There is, however, an interesting background to current software use within Cuba that makes it unique among several less-developed countries. Apart from the well-known advantages, FOSS use could be essential to shape the future scenario of Cuba. The present paper first delineates some of the Cuban background, basically characterized by lack of freedom in technology ownership and access to external information. The potential of FOSS use within existing conditions in Cuba is then analyzed. Finally, conclusions are provided on the basis of a survey carried out in Cuba, arguing that there needs to be stronger political will to reduce gaps between goals and implementation reality to achieve intrinsic advantages of FOSS use successfully.","2006","2025-04-25 16:48:58","2025-04-25 16:48:58","","1-17","","1","3","","","","","","","","","","English","","","","","","","Place: UNIV SOUTHERN CALIFORNIA, KERCKHOFF HALL, 734 W ADAMS BLVD, MC7725, LOS ANGELES, CA 90089 USA Publisher: USC ANNENBERG PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Having tried both ways allows us to retrospectively; compare the effectiveness of “from scratch” implementation versus software evolution. By using the code bases of GNU GCC and Linux for the adaptation approach we gained valuable experiences with the comprehension and adaptation of large but sparsely documented code bases. In most cases, the adaptation of existing software proved to be by-far more effective than implementing from scratch. Surprisingly, the effort needed to comprehend the existing voluminous source codes repeatedly proved to be less than expected. In this paper we discuss our positive and negative experiences and the various factors influencing success and failure.

Against conventional wisdom this approach has been wildly successful in the general software market-probably because the openness lets programmers the world over obtain, critique, use, and build upon the source code without licensing fees. Linux, a UNIX-like operating system, is the best known success. But computer scientists at the University of California, Berkeley began the tradition of software sharing in the mid 1970s with BSD UNIX and distributed the major internet network protocols as source code without a fee. Medical informatics has its own history of Open Source distribution: Massachusetts General's COSTAR and the Veterans Administration's VISTA software have been distributed as source code at no cost for decades. Bioinformatics, our sister field, has embraced the Open Source movement and developed rich libraries of open-source software. Open Source has now gained a tiny foothold in health care (OSCAR GEHR, OpenEMed). Medical informatics researchers and funding agencies should support and nurture this movement. In a world where open-source modules were integrated into operational health care systems, informatics researchers would have real world niches into which they could engraft and test their software inventions. This could produce a burst of innovation that would help solve the many problems of the health care system. We at the Regenstrief Institute are doing our part by moving all of our development to the open-source model. (C) 2002 Elsevier Science Ireland Ltd.

To this end, we contribute a process for decomposing trust in a complex large-scale system into key trust relationships, systematically identifying behavior-based indicators for the components of trust for a given relationship, and in turn operationalizing data-driven metrics for those indicators, allowing for the wide-scale measurement of trust in practice.","2024","2025-04-25 16:48:58","2025-04-25 16:48:58","","57-61","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox).

In other sectors, such as telecommunication or cloud computing, open-source software has already proven capable of transforming entire industries, by speeding up development and lowering development costs while achieving high levels of stability, interoperability, and security. However, the energy sector has not yet embraced open-source software to the same level. We discuss how existing open-source software principles can be applied to the unique challenges of the energy sector during the transition towards higher penetration of renewable energy resources. To provide an overview of the current state of the open-source software landscape, we collected and analyzed 388 open-source projects, in terms of project activities, community composition, relevant licenses, and commonly used programming languages. One finding was that the majority of projects are currently driven by academic contributors, but that commercial players do also play a role, and we identify positive examples of collaboration between the two, mostly related to standardization.","2023-08","2025-04-25 16:48:59","2025-04-25 16:48:59","","","","16","16","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","FOSS; free software; community; open-source software; licenses; energy transition; future distribution grid; power systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma, allowing for early diagnosis and intervention. We have developed Specvis, a free and open-source application written in Java programming language that can run on any personal computer to meet this requirement (http://www. specvis. pl/). Specvis was tested on glaucomatous, retinitis pigmentosa and stroke patients and the results were compared to results using the Medmont M700 Automated Static Perimeter. The application was also tested for inter-test intrapersonal variability. The results from both validation studies indicated low inter-test intrapersonal variability, and suitable reliability for a fast and simple assessment of visual field impairment. Specvis easily identifies visual field areas of zero sensitivity and allows for evaluation of its levels throughout the visual field. Thus, Specvis is a new, reliable application that can be successfully used for visual field examination and can fill the gap between confrontation and perimetry tests. The main advantages of Specvis over existing methods are its availability (free), affordability (runs on any personal computer), and reliability (comparable to high-cost solutions).","2017-10-13","2025-04-25 16:48:59","2025-04-25 16:48:59","","","","10","12","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To better understand the turnover of members in OSS projects, we base our study on Herzberg's two-factor theory to investigate whether hygiene factors will lead to members' dissatisfaction. At the same time, we draw on Mobley's model of withdrawal decision process to hypothesize the relationship between dissatisfaction and perceived turnover. We develop a research model and present hypotheses that should be tested in the future. To empirically assess this model, we intend to survey OSS project members through the largest development platform Sourceforge.

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them.

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg's motivation-hygiene framework, we explore how developers' perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022","2025-04-25 16:49:00","2025-04-25 16:49:00","","165-195","","1","23","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","Motivation; Open Source Software; Change Over Time; Code Contribution; Multilevel Growth Analysis; Payment; Value Fit","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Similarly, testability is a residual software property which the developers and users no longer ignore. This is because if the testability of software is high, the test effort and development cost decrease proportionally. This is the case because test effort is highly affected by testability. In this paper, we investigate the relationship between test effort and success of the open source software by employing source codes and easily accessible parameters from the repository. Moreover, the proposed methods are empirically examined by analyzing 17 open source software projects. According to the empirical results, a meaningful positive correlation is obtained between test effort and success.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

Adequate tool support may pave the road to effective risk management and ensure the sustainability of such activity. In this paper, we present the RISCOSS platform for managing risks in OSS adoption. RISCOSS builds upon a highly configurable data model that allows customization to several types of scopes. It implements two different working modes: exploration, where the impact of decisions may be assessed before making them; and continuous assessment, where risk variables (and their possible consequences on business goals) are continuously monitored and reported to decision-makers. The blackboard-oriented architecture of the platform defines several interfaces for the identified techniques, allowing new techniques to be plugged in.","2015","2025-04-25 16:49:00","2025-04-25 16:49:00","","124-133","","","451","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: IFIP WG 2 13; Google ISSN: 1868-4238 Type: Proceedings Paper","","","","Open source software; OSS; Risk management; Open source projects; Open source adoption; Software platform","","Damiani, E; Frati, F; Riehle, D; Wasserman, AI","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Consequently, support in the exchange of data, information, and knowledge is becoming the key issue in computer technology today. The increasing volume of data available on the Web makes information retrieval a tedious and difficult task. Researchers are now exploring the possibility of creating a semantic web, in which meaning is made explicit, allowing machines to process and integrate web resources intelligently. The vision of the semantic web introduces the next generation of the Web by establishing a layer of machine-understandable data. The success of the semantic web depends on the easy creation, integration and use of semantic data, which will depend on web ontology. The faceted approach towards analyzing and representing knowledge given by S R Ranganathan would be useful in this regard. Ontology development in different fields is one such area where this approach given by Ranganathan could be applied. This paper presents a case of developing ontology for the field of banking.","2015","2025-04-25 16:49:00","2025-04-25 16:49:00","","281-285","","4","62","","","","","","","","","","English","","","","","","","Place: DR K S KRISHNAN MARG, PUSA CAMPUS, NEW DELHI 110 012, INDIA Publisher: NATL INST SCIENCE COMMUNICATION-NISCAIR Type: Article","","","","Open Source Software; Ontology; Ranganathan S R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are many open-source architecture frameworks for UAS that claim the autonomous operation of UAS, but they still have two main open issues: (1) level of autonomy, being in most of the cases limited and (2) versatility, being most of them designed specifically for some applications or aerial platforms. As a response to these needs and issues, this paper presents Aerostack, a system architecture and open-source multi-purpose software framework for autonomous multi-UAS operation. To provide higher degrees of autonomy, Aerostack's system architecture integrates state of the art concepts of intelligent, cognitive and social robotics, based on five layers: reactive, executive, deliberative, reflective, and social. To be a highly versatile practical solution, Aerostack's open-source software framework includes the main components to execute the architecture for fully autonomous missions of swarms of UAS; a collection of ready-to-use and flight proven modular components that can be reused by the users and developers; and compatibility with five well known aerial platforms, as well as a high number of sensors. Aerostack has been validated during three years by its successful use on many research projects, international competitions and exhibitions. To corroborate this fact, this paper also presents Aerostack carrying out a fictional fully autonomous indoors search and rescue mission.","2016","2025-04-25 16:49:00","2025-04-25 16:49:00","","332-341","","","","","","","International Conference on Unmanned Aircraft Systems","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Robot & Automat Soc; IEEE CSS; MCA ISSN: 2373-6720 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we present ELIGERE, an open source decision support system targeted at engineering design applications. It allows to rank multiple design solutions with respect to different evaluation criteria according to the evaluations provided by a group of experts. ELIGERE is composed by three main modules: (1) a distributed web application, for generation and participation to the decision making session; (2) a mathematical engine, based on the fuzzy analytical hierarchy process, to quantify the results of the decision making session according to the evaluation of the experts; (3) a relational database, to collect and store data. The most important contribution of this paper is introducing a practical and effective software tool that facilitates decision-making analysis based on the fuzzy analytical hierarchy process, thereby allowing better-informed choices on concept selection, as it has been designed with a specific focus on the engineering field. In this paper we describe the key concepts of ELIGERE and its modalities of use in several real use cases.

Measurements of these metrics tell us various key aspects of system. This in turn supports knowledgeable decision making by which we can enhance the quality of system. Maintenance is a process of revisions or corrections made to software systems after their first release. The key feature of software development is change. Hence it is important to develop software that is easy to modify and is thus maintainable. This paper evaluates the existing Oman and Hagemeister maintainability index model which calculates maintainability index (MI) based on Cyclomatic Complexity, Lines of code and Halsted volume. For this purpose, software metric datasets of Lucene, which is open source software of 163085 lines of code are used, and it is shown that the existing Oman and Hagemeister maintainability index mode model is not a good a predictor of maintainability. A new maintainability index model is proposed with a new set of predictor metrics. The new proposed model is a marked improvement over the existing Oman and Hagemeister maintainability index model.

These efforts aim to identify common elements in the development process between multiple open source software (OSS) projects. However, the complexity inherent to OSSD process modeling puts significant demands on the modeling language. Objective: In this paper, we propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. Method: We investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. DEMO models were constructed to describe the NetBeans Requirements and Release process. In addition, the quality of these DEMO models was evaluated using a quality framework for conceptual modeling. Results: Our results showed that our DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. In addition, the evaluation of the models developed in this paper by using the quality framework for conceptual modeling showed that the models were of high quality. Conclusions: We have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models. However, given some potential drawbacks with respect to understandability and implementability, we primarily propose the use of DEMO within OSSD process modeling as an analysis tool that should be complemented with other techniques and models for communication and reenactment purposes.

Despite that a lot of relevant research focusing on this topic, understanding the structures and dynamics of communities around open-source software projects remains a tedious and challenging task. As a result, an easily accessible and useful application that enables project developers to gain awareness of the status and development of the project communities is desirable. In this paper, we present MyCommunity, a web-based online application system to automatically extract communication-based community structures from social coding platforms such as GitHub. Based on the detected community structures, the system analyzes and visualizes the community evolution history of a project with a set of semantic-rich events, and quantify the strength of community evolution with respect to different events with a series of indexes. Built-in support to quantitative analysis and machine learning tasks based on the quantitative evolutionary events are provided. We demonstrate the usefulness of the system by presenting its ability in predicting project success or failure with the community evolution features. The results suggest the system achieves a prediction accuracy of 88.5% with commonly available machine learning models.","2022","2025-04-25 16:49:01","2025-04-25 16:49:01","","38-45","","","13724","","","","Lecture Notes in Computer Science","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","ISSN: 0302-9743 Type: Proceedings Paper","","","","Community evolution; Open source community analysis; Web-based application","","Chbeir, R; Huang, H; Silvestri, F; Manolopoulos, Y; Zhang, Y","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Several OSS systems have achieved significant market success but they are rather server-side applications, such as the Apache Web server, MySQL database server, or other components of IT infrastructure. On the other hand, penetration of OSS systems on the market of desktop applications is rather limited and it is virtually dominated by products of one software vendor, i.e., Microsoft. In this chapter, the benefits and barriers of OSS implementation in Poland are investigated. Based on the well-known technology organization environment model of IT technology adoption of a simple model was developed and evaluated empirically, based on the data from the survey of 178 enterprises and public institutions.

Literature Review Highlighting the problem, we cite research related to using undergraduates as participants, pedagogical value of these experiences, and current trends in software distribution. We then provide evidence of successful implementation of open-source software (OSS) in educational settings, and conclude with OSS options capable of addressing the problem of access. Teaching Implications By providing students research experiences, both as a researcher and as a participant, we enhance their understanding of this process. Secondary to this, we can foster within them a skill set that is valuable to disciplines outside of academia.

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 16:49:01","2025-04-25 16:49:01","","28-36","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The objective: to explore the evolution of a long-lived open source project with the intention of learning how code evolution has progressed over time. This investigation provides a case study of Nethack, an enormously popular open source game that has been in development for more than a decade. The Goal Question Metric approach was employed to derive measurement goals for the evaluation of open source software (OSS) evolution in Nethack. According to Lehman's laws, the incremental growth size of successive releases tends to decline during the active life of an evolving program. Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased. These findings raise questions concerning the evolution of other OSS applications.","2006","2025-04-25 16:49:01","2025-04-25 16:49:01","","47+","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: NASA Software Engn Lab; NASA Goddard Space Flight Ctr, Informat Syst Div; IEEE Comp Soc, TCSE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding the content types of forum messages and issue trackers can provide information about the extent to which requests are being addressed and issues are being resolved, the percentage of issues that are not being fixed, the cases where the user acknowledged that the issue was successfully resolved, etc. These indicators can provide potential adopters of the OSS with estimates about the level of available support.

The lack of established metrics makes it difficult to formulate such strategy. While many projects have been formed and created, only a few managed to remain active. With the majority of these projects failing, firms need a reliable set of criteria to assess what makes a project appealing not only to developers but also to visitors, users and commercial sponsors. In this paper, we develop a theoretical model to explore the contextual and causal factors of project attractiveness in inducing activities such as source code contribution, software maintenance, and usage. We test our model with data derived from more than 4000 projects spanning 4 years. Our main findings include that projects' set of conditions such as license restrictiveness and their available resources provide the context that directly influence the amount of work activities observed in the projects. It was also found that indirect and unintended contributions such as recommending software, despite of being non-technical, cannot be ignored for project activeness, diffusion and sustainability. Finally, our analysis provide evidence that higher attractiveness leads to more code-related activities with the downside of slowing down responsiveness to address projects' tasks, such as the implementation of new features and bug fixes. Our model underscores the significance of the reinforcing effects of attractiveness and work activities in open source projects, giving us the opportunity to discuss strategies to manage common traps such as the liability of newness. We conclude by discussing the applicability of the research model to other user-led initiatives. (C) 2012 Elsevier B.V.

National, regional, and local government are using OSS in increasing numbers, yet the adoption rate is still very low. This study considers if it is possible from an organizational perspective for small to medium-sized cities to provide services and conduct business using only open source software (OSS). We examine characteristics of municipal government that may influence the adoption of OSS for the delivery of services and to conduct city business. Three characteristics are considered to develop an understanding of city behavior with respect to OSS: capability, discipline, and cultural affinity. Each of these general characteristics contributes to the successful adoption and deployment of OSS by cities. Our goal was to determine the organizational characteristics that promote the adoption of OSS. We conducted a survey to support this study resulting in 3316 responses representing 1286 cities in the Unites States and Canada. We found most cities do not have the requisite characteristics to successfully adopt OSS on a comprehensive scale and most cities not currently using OSS have not future plans for OSS.","2009","2025-04-25 16:49:01","2025-04-25 16:49:01","","1044+","","","","","","","Lecture Notes in Engineering and Computer Science","","","","INT ASSOC ENGINEERS-IAENG","UNIT 1, 1-F, 37-39 HUNG TO ROAD, KWUN TONG, HONG KONG, 00000, PEOPLES R CHINA","English","","","","","","","Backup Publisher: IAENG Soc Artificial Intelligence; IAENG Soc Bioinformat; IAENG Soc Comp Sci; IAENG Soc Data Min; IAENG Soc Elect Engn; IAENG Soc Imaging Engn; IAENG Soc Ind Engn; IAENG Soc Internet Comp & Web Serv; IAENG Soc Oper Res; IAENG Soc Sci Comp; IAENG Soc Software Engn; IAENG Soc Wireless Networks; IAENG Soc HIV/AIDS ISSN: 2078-0958 Type: Proceedings Paper","","","","Open Source Software; City Government; Municipal Government","","Ao, SI; Douglas, C; Grundfest, WS; Burgstone, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The utilization of OSS is essential as costs around the world continue to rise for education, institutions must become innovative in the ways they teach and grow Science, Technology, Engineering, & Mathematics (STEM) majors. To do this effectively professors and administrative staff should push toward the utilization of OSS and other available tools to enhance or supplement currently available tools with minimal integration costs. The OSS applications would allow students the ability to learn critical technological skills for success at small fraction of the cost. OSS also provides faculty members the ability to have students dissect source code, analyze network traffic, create virtual instances of real Operating Systems (OSs), and prepare students for low level software development. It is critical that all institutions look at alternatives in providing training and delivering educational material regardless of limitations going forward as the world continues to be more global due to the increased use of technologies everywhere. Through reviewing the available technology, possible implementations of these technologies, and the application of these items in industry could provide a starting point in integrating these tools into academia.

These have been used as the basis to support the discovery of successful genetic modifications of the microbial metabolism to address industrial goals. However, the use of these methods has been restricted to bioinformaticians or other expert researchers. The main aim of this work is, therefore, to provide a user-friendly computational tool for Metabolic Engineering applications. Results: OptFlux is an open-source and modular software aimed at being the reference computational application in the field. It is the first tool to incorporate strain optimization tasks, i.e., the identification of Metabolic Engineering targets, using Evolutionary Algorithms/Simulated Annealing metaheuristics or the previously proposed OptKnock algorithm. It also allows the use of stoichiometric metabolic models for (i) phenotype simulation of both wild-type and mutant organisms, using the methods of Flux Balance Analysis, Minimization of Metabolic Adjustment or Regulatory on/off Minimization of Metabolic flux changes, (ii) Metabolic Flux Analysis, computing the admissible flux space given a set of measured fluxes, and (iii) pathway analysis through the calculation of Elementary Flux Modes. OptFlux also contemplates several methods for model simplification and other pre-processing operations aimed at reducing the search space for optimization algorithms. The software supports importing/exporting to several flat file formats and it is compatible with the SBML standard. OptFlux has a visualization module that allows the analysis of the model structure that is compatible with the layout information of Cell Designer, allowing the superimposition of simulation results with the model graph. Conclusions: The OptFlux software is freely available, together with documentation and other resources, thus bridging the gap from research in strain optimization algorithms and the final users. It is a valuable platform for researchers in the field that have available a number of useful tools. Its open-source nature invites contributions by all those interested in making their methods available for the community. Given its plug-in based architecture it can be extended with new functionalities. Currently, several plug-ins are being developed, including network topology analysis tools and the integration with Boolean network based regulatory models.","2010-04-19","2025-04-25 16:49:02","2025-04-25 16:49:02","","","","","4","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We found through a qualitative analysis that the core developers in this system include doctors and clinicians who also use the product. We also found that the size of the community associated with the project is an order of magnitude smaller than predicted, yet still maintains a high degree of responsiveness to issues raised by users.

This paper proposes a system security assessment method that integrates the risk relationships of open source software (OSS). Firstly, an OSS risk propagation relationship graph is constructed, and the Fuzzy Analytic Hierarchy Process (FAHP)-entropy weight method is adopted to allocate weights to the weakness assessment indicators of OSS, thereby improving the accuracy of quantifying OSS propagation risks. Then, on the attack graph, the analysis of threat values to host nodes and the probability of successful attack paths are optimized from three perspectives: vulnerabilities, OSSSC, and hosts. Experimental results demonstrate that this method, by combining open source risk factors and conducting multi-dimensional analysis, can more effectively assess the security threats faced by systems, providing a more accurate basis for security defense.","2024","2025-04-25 16:49:02","2025-04-25 16:49:02","","21-27","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: N Minzu Univ; Xidian Univ; Future Univ Hakodate; Chuzhou Univ; Ikueikan Univ Type: Proceedings Paper","","","","host status; OSSSC; system security; vulnerability assessment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Closed-loop experiments provide unique insights into brain dynamics and function. To facilitate a wide range of closed-loop experiments, we created an open-source software platform that enables high-performance real-time processing of streaming experimental data. Approach. We wrote Falcon, a C++ multi-threaded software in which the user can load and execute an arbitrary processing graph. Each node of a Falcon graph is mapped to a single thread and nodes communicate with each other through thread-safe buffers. The framework allows for easy implementation of new processing nodes and data types. Falcon was tested both on a 32-core and a 4-core workstation. Streaming data was read from either a commercial acquisition system (Neuralynx) or the open-source Open Ephys hardware, while closed-loop TTL pulses were generated with a USB module for digital output. We characterized the round-trip latency of our Falcon-based closed-loop system, as well as the specific latency contribution of the software architecture, by testing processing graphs with up to 32 parallel pipelines and eight serial stages. We finally deployed Falcon in a task of real-time detection of population bursts recorded live from the hippocampus of a freely moving rat. Main results. On Neuralynx hardware, round-trip latency was well below 1 ms and stable for at least 1 h, while on Open Ephys hardware latencies were below 15 ms. The latency contribution of the software was below 0.5 ms. Round-trip and software latencies were similar on both 32- and 4-core workstations. Falcon was used successfully to detect population bursts online with similar to 40 ms average latency. Significance. Falcon is a novel open-source software for closed-loop neuroscience. It has sub-millisecond intrinsic latency and gives the experimenter direct control of CPU resources. We envisage Falcon to be a useful tool to the neuroscientific community for implementing a wide variety of closed-loop experiments, including those requiring use of complex data structures and real-time execution of computationally intensive algorithms, such as population neural decoding/encoding from large cell assemblies.","2017-08","2025-04-25 16:49:02","2025-04-25 16:49:02","","","","4","14","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP PUBLISHING LTD Type: Article","","","","open-source software; closed-loop neuroscience; multi-threaded software; online burst detection; real-time processing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. Methods: This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Observations: Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Conclusion: Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future. The impact of these new technologies is particularly effective in image communication, PACS and teleradiology. (C) 2010 Elsevier Ireland Ltd.

The PCA denoising method is applied to ten scans of EBSPs from the same region of interest of a recrystallised nickel sample acquired with a decreasing S/N, achieved by reducing the exposure time while increasing the camera gain accordingly. That PCA denoising increases S/N in EBSPs is demonstrated by comparing indexing success rates after both Hough and dictionary indexing (HI and DI) of the Ni patterns having undergone one of four processing routes: i) standard static and dynamic background corrections (standard corrections), ii) standard corrections and pattern averaging with the four closest neighbours, iii) standard corrections and PCA denoising, and iv) standard corrections and pattern averaging followed by PCA denoising. Both pattern averaging and PCA denoising increases the indexing success rates for both indexing approaches for the studied Ni scans, with the former processing route providing the better success rates. The best success rates are obtained after pattern averaging followed by PCA denoising. The potential of PCA denoising to reveal additional pattern details compared to standard corrections and pattern averaging is demonstrated in a pattern from an orthoclase (KAlSi3O8) grain in a geological sample. Software code, and the Ni data sets, are released alongside this article as part of KIKUCHIPY, an open-source software package dedicated to processing and analysis of EBSPs.","2020","2025-04-25 16:49:02","2025-04-25 16:49:02","","","","","891","","","","IOP Conference Series-Materials Science and Engineering","","","","IOP PUBLISHING LTD","DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND","English","","","","","","","Backup Publisher: European Microbeam Anal Soc; Ametek GmbH, Edax Business Unit; Ametek, CAMECA Business Unit; Bruker Nano GmbH; European Commiss, JRC Directorate G Nucl Safety & Secur; Jeol; Micro Nano; Norwegian Univ Sci & Technol; Probe Software; NordicNano Solut AB; Target Messtechnik; TESCAN ORSAY HOLDING a s; Thermo Fisher Sci ISSN: 1757-8981 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While intra-operative ultrasound (iUS) guidance has shown clear potential to reduce surgery time, compared with clinical computed tomography (CT) guidance, rapid registration aiming to correct for patient misalignment has not been addressed. In this article, we present an open-source platform for pedicle screw navigation using iUS imaging. The alignment method is based on rigid registration of CT to iUS vertebral images and has been designed for fast and fully automatic patient re-alignment in the operating room. Two steps are involved: first, we use the iUS probe's trajectory to achieve an initial coarse registration; then, the registration transform is refined by simultaneously optimizing gradient orientation alignment and mean of iUS intensities passing through the CT-defined posterior surface of the vertebra. We evaluated our approach on a lumbosacral section of a porcine cadaver with seven vertebral levels. We achieved a median target registration error of 1.47 mm (100% success rate, defined by a target registration error <2 mm) when applying the probe's trajectory initial alignment. The approach exhibited high robustness to partial visibility of the vertebra with success rates of 89.86% and 88.57% when missing either the left or right part of the vertebra and robustness to initial misalignments with a success rate of 83.14% for random starts within +/- 20 degrees rotation and +/- 20 mm translation. Our graphics processing unit implementation achieves an efficient registration time under 8 s, which makes the approach suitable for clinical application.

We conceptualize project success in terms of success building a community, as assessed by graduation from the Incubator. We compare successful and unsuccessful projects on volume of communication by core (committer) and peripheral community members and on use of inclusive pronouns as an indication of efforts to create intimacy among team members. An innovation of the paper is that use of inclusive pronouns is measured using natural language processing techniques. We find that core and peripheral members differ in their volume of contribution and in their use of inclusive pronouns, and that volume of communication is related to project success.","2016","2025-04-25 16:49:02","2025-04-25 16:49:02","","45-56","","","472","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","Backup Publisher: IFIP WG 2 13; Software Ctr; Informat & Commun Technol; Business Reg Goteborg ISSN: 1868-4238 Type: Proceedings Paper","","","","","","Crowston, K; Hammouda, I; Lundell, B; Robles, G; Gamalielsson, J; Lindman, J","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To lead an OSS project to a successful conclusion, researchers study how developers change source codes called patches in project repositories. In existing studies, we found an argument in the conventional patch acceptance detection procedure. It was so simplified that it omitted important cases from the analysis, and would lead researchers to wrong conclusions. In this research, we propose an algorithm to overcome the problem. To prove out our algorithm, we constructed a framework and conducted two case studies.

Open-source software allows members of the public to study, customize, and operate their own local copies of the software and source code, often without monetary fees. As such, releasing SAGES as open-source software assures prospective users that they retain complete control over the health data collected by SAGES-based systems, and aligns well with the model of self-sustainability intended for the operation of SAGES systems in resource-limited settings. Preparing two SAGES tools, OpenESSENCE and SAGES Mobile, for release as open-source software projects entailed a multifaceted, months-long effort that spanned policy, technical, and community considerations. This article describes the issues, trade-offs, and decisions that were addressed leading up to the successful open-source release of OpenESSENCE and SAGES Mobile in June 2013.

In such platforms, developers have to collaborate and deal with issues of collaboration in open-source software development. Although collaboration is challenging, collaborative development produces better software systems than any developer could produce alone. Several approaches have investigated collaboration challenges, for instance, by proposing or evaluating models and tools to support collaborative work. Despite the undeniable importance of the existing efforts in this direction, there are few works on collaboration from perspectives of developers. In this work, we aim to investigate the perceptions of open-source software developers on collaborations, such as motivations, techniques, and tools to support global, productive, and collaborative development. Following an ad hoc literature review, an exploratory interview study with 12 open-source software developers from GitHub, our novel approach for this problem also relies on an extensive survey with 121 developers to confirm or refute the interview results. We found different collaborative contributions, such as managing change requests. Besides, we observed that most collaborators prefer to collaborate with the core team instead of their peers. We also found that most collaboration happens in software development (60%) and maintenance (47%) tasks. Furthermore, despite personal preferences to work independently, developers still consider collaborating with others in specific task categories, for instance, software development. Finally, developers also expressed the importance of the social coding platforms, such as GitHub, to support maintainers, and contributors in making decisions and developing tasks of the projects. Therefore, these findings may help project leaders optimize the collaborations among developers and reduce entry barriers. Moreover, these findings may support the project collaborators in understanding the collaboration process and engaging others in the project.","2023-05","2025-04-25 16:49:03","2025-04-25 16:49:03","","","","5, SI","35","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","distributed collaboration; collaborative software development; collaboration in software development; open-source software projects; sustained developer community participation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 16:49:03","2025-04-25 16:49:03","","116-150","","1","32","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","social networks; software development; open source software development; team formation; project success; exploitation and exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the “virtuous circle” supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other. Each of these findings is related to the sustainability of these projects.","2013-01","2025-04-25 16:49:03","2025-04-25 16:49:03","","13-19","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although existing research recognizes the importance of trust, there is a lack of an effective and scalable computational method to measure trust in an OSS community. Consequently, OSS project members must rely on subjective inferences based on fragile and incomplete information for trust-related decision making. We propose an automated approach to assist a developer in identifying the trustworthiness of another developer. Our two-fold approach, first, computes direct trust between developer pairs who have interacted previously by analyzing their interactions via natural language processing. Second, we infer indirect trust between developers who have not interacted previously by constructing a community-wide developer network and propagating trust in the network. A large-scale evaluation of our approach on a GitHub dataset consisting of 24,315 developers shows that contributions from trusted developers are more likely to be accepted to a project compared to contributions from developers who are distrusted or lacking trust from project members. Further, we develop a pull request classifier that exploits trust metrics to effectively predict the likelihood of a pull request being accepted to a project, demonstrating the practical utility of our approach.","2019-12-30","2025-04-25 16:49:03","2025-04-25 16:49:03","","","","12","14","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We extract a series of measures based on those used in traditional inspection experiments. We measure the frequency of review, the size of the contribution under review, the level of participation during review, the experience and expertise of the individuals involved in the review, the review interval, and the number of issues discussed during review. We create statistical models of the review efficiency, review interval, and effectiveness, the issues discussed during review, to determine which measures have the largest impact on review efficacy. We find that OSS peer reviews are conducted asynchronously by empowered experts who focus on changes that are in their area of expertise. Reviewers provide timely, regular feedback on small changes.

An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweight open source systems for patient and sample information management. Results: We present a web-based tool for submission, management and retrieval of sample and research subject data. The system secures confidentiality by separating anonymized sample information from individuals' records. It is simple and generic, and can be customised for various biomedical studies. Information can be both entered and accessed using the same web interface. User groups and their privileges can be defined. The system is open-source and is supplied with an on-line tutorial and necessary documentation. It has proven to be successful in a large international collaborative project. Conclusion: The presented system closes the gap between the need and the availability of lightweight software solutions for managing information in biomedical studies involving human research subjects.","2007-02-09","2025-04-25 16:49:03","2025-04-25 16:49:03","","","","","8","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, since reused components are (by definition) generic, they need to be customized and integrated into a specific system before they can be useful. Since this integration is system-specific, the integration effort is non-negligible and increases maintenance costs, especially if more than one component needs to be integrated. This paper performs an empirical study of multi-component integration in the context of three successful open source distributions (Debian, Ubuntu and FreeBSD). Such distributions integrate thousands of open source components with an operating system kernel to deliver a coherent software product to millions of users worldwide. We empirically identified seven major integration activities performed by the maintainers of these distributions, documented how these activities are being performed by the maintainers, then evaluated and refined the identified activities with input from six maintainers of the three studied distributions. The documented activities provide a common vocabulary for component integration in open source distributions and outline a roadmap for future research on software integration.","2016-06","2025-04-25 16:49:03","2025-04-25 16:49:03","","960-1001","","3","21","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Debian; Software reuse; Open source distributions; Software integration; Ubuntu and FreeBSD","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores a prediction method based on fuzzy time series for predicting the future commit activity in open source software (OSS) projects. The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems. It is found that the predicted results of the computational method outperform various ARIMA models. Towards the end, a commit prediction model is used for each project to analyse the trends in their commit activity.","2016-10","2025-04-25 16:49:03","2025-04-25 16:49:03","","136-146","","5","10","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","public domain software; open source software projects; OSS projects; time series; ARIMA model; autoregressive integrated moving average models; autoregressive moving average processes; commit activity prediction; development community; fuzzy analysis; fuzzy set theory; fuzzy time series-based prediction method; software development management; software evolution prediction; time variant difference parameter","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.","2015-03","2025-04-25 16:49:04","2025-04-25 16:49:04","","224-237","","1","26","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software; intrinsic motivation; firm attributes; firm sponsorship; voluntary contributions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software is a recent and important example. Copyright restrictions on open-source projects stipulate that any user may modify the software so long as any resulting innovation is freely available to all. In economic parlance, the innovation is a public good. The economic theory of public-good provision raises a number of important questions. Who contributes to such a project, and who free rides? How might a social planner exploit the interdependence of project components to encourage contributions? Under what conditions will such actions result in successful provision? Using a simple game-theoretic framework and recent results from the study of equilibrium selection, we attempt to answer these questions. Under reasonable assumptions of asymmetry and less than complete information, the most efficient providers will contribute. Contributions can be elicited by `integrating' the provision process when providers are sufficiently optimistic about the success of the project. Otherwise, the social planner may be better off `separating' the components so that individual contributions are independent of each other. The analysis yields recommendations for the leaders of open-source projects and other similar collective-action problems.","2002","2025-04-25 16:49:04","2025-04-25 16:49:04","","446-461","","4","18","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there were few developers being paid directly for maintaining OSS projects in the past. The GitHub Sponsors program that brings financial supports to the general OSS developers in GitHub-the world's largest OSS platform may make a difference on this situation in the future. In this paper, we present a data set on GitHub Sponsors and conduct a data-driven study to analyze the participants of the program and the impact of sponsorships to developers' activities and their projects' outcomes and qualities. The results of our survey suggest that most developers state they will contribute more with sponsorships and provide some privilege for their sponsors. And through quantitative study, we find that developers make more contributions on GitHub after they got/offered sponsorships. Moreover, gaining sponsorship also has a weakly positive impact on developers' collaborators that did not get sponsorship. And not only developers, but their own or contributed projects also can be motivate by sponsorships. Our findings are useful to the community by understanding the impact of sponsorships on users' activities and projects' progress and sustainability, and helping the managers to improve the current financial support mechanism.","2022","2025-04-25 16:49:04","2025-04-25 16:49:04","","924-933","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc Type: Proceedings Paper","","","","Open Source Software; Data-Driven Study; Financial Support; GitHub Sponsors","","Leong, HV; Sarvestani, SS; Teranishi, Y; Cuzzocrea, A; Kashiwazaki, H; Towey, D; Yang, JJ; Shahriar, H","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

Therefore, it is important to understand the factors affecting OSSD project success as measured by project popularity. While technical factors such as license and compatibility with certain operating systems have a direct influence on the popularity of OSSD projects, development-related factors also have latent impacts on the popularity of OSSD projects. Therefore, we collect data on 445 projects and successfully build a structural equation model (SEM) which depicts the inherent relationships between development-related factors and OSSD project popularity.

Cross-language software similarity detection is inherently more challenging due to variations in language, application structures, support libraries used, and naming conventions. In this paper we propose a novel model, CroLSim, to detect similar software applications across different programming languages. We define a semantic relationship among cross-language libraries and API methods (both local and third party) using functional descriptions and a word-vector learning model. Our experiments show that CroLSim can successfully detect cross-language similar software applications, which outperforms all existing approaches (mean average precision rate of 0.65, confidence rate of 3.6, and 75% highly rated successful queries). Furthermore, we applied CroLSim to a source code repository to see whether our model can recommend cross-language source code fragments if queried directly with source code. From our experiments we found that CroLSim can recommend cross-language functional similar source code when source code is directly used as a query (average precision=0.28, recall=0.85, and F-Measure=0.40).

OSS project success is reflected in two forms: popularity and knowledge creation. Extending the extant OSS literature, we theorize a contingent role of interproject connectedness. In particular, we posit three points: (1) an OSS project with more structural holes achieves higher popularity; (2) an OSS project with fewer structural holes yields higher knowledge creation; and (3) these two relationships are enhanced by an increase in project maturity. Using a dataset longitudinally collected from SourceForge.net, we found that OSS projects with widespread connectedness are more popular. This is especially so for those OSS projects in the mid-mature stage. We also found that OSS projects with a cohesive network achieve higher knowledge creation, irrespective of their maturity. Findings from our study can contribute to OSS literature by identifying OSS projects that are more likely to be successful.","2021-03","2025-04-25 16:49:04","2025-04-25 16:49:04","","","","1","30","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source software; Popularity; Maturity; Interproject connectedness; Knowledge creation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This surge in unmanned aerial vehicles has increased attention towards monitoring tasks in vital areas, such as urban spaces for security, surveillance or Internet of the Things applications. In this sense, we propose an open-source software-in-the-loop approach that integrates the complete navigation experience, accounting for potential wind-related effects, and providing realistic 3D modeling of scenarios encompassing open spaces in city landscapes. Our work introduces a wind perturbation estimation strategy, which models the wind effect as an external force along the Zaxis based on altitude variations from real flights. Validation was conducted using real data flights with a quadrotor aiding the navigation with Ardupilot and QgroundControl as a ground station. To complement the experiments we include a small test with a fixed-wing plane to asses the software-in-the-loop accuracy on larger trajectories.

In the case of orthopaedic and dental implants it was found that geometry and surface topography are crucial for short and long-term success of the implant, due to its effects in osseointegration. Properties of implant surfaces have been studied in the last decade in a concentrated effort to improve osseointegration process and implant success. Several researchers have proved that roughness of implant surface is related to healing time and integration between the implants and the bone, but the parameters on the surface creation are not fully controllable with current processes. In this work, computational algorithms are proposed for implant surface design in order to control the parameters required for this application. As a result it is presented an open-source software tool, called POMES - Porous and Modifications for Engineering Surfaces - , to design porous/roughness on top of surfaces in any geometry. Additionally, an example model was fabricated using POMES and additive manufacturing. (C) 2015 The Authors.

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-forprofit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 16:49:05","2025-04-25 16:49:05","","32-39","","","","","","","","","","","","","English","","","","","","","Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, download counts and averages do not convey as much information as the patterns in the original downloads time series. In this research, we propose a method to increase the expressiveness of mere download rates by considering download patterns against software releases. We apply experimentally our method to the most downloaded projects of Source Forge's history crawled through the FLOSSMole repository.

There are continuing debates over the future of software and, in particular, the competition between OSS and proprietary software. Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. The government environment is changing rapidly in areas as diverse as homeland security and social services. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied-especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 16:49:05","2025-04-25 16:49:05","","227-238","","2","44","","","","","","","","","","English","","","","","","","Place: 1 NEW ORCHARD ROAD, ARMONK, NY 10504 USA Publisher: IBM CORP Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lens of administrative complexity associated with OSS adoption. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that value for money and fit for purpose criteria described in Commonwealth Procurement Guidelines were the major enablers of OSS adoption.","2012","2025-04-25 16:49:05","2025-04-25 16:49:05","","","","2","17","","","","","","","","","","English","","","","","","","Place: BLDG 11, KIRINARI ST, BRUCE, ACT 2617, AUSTRALIA Publisher: UNIV CANBERRA, FAC INFORMATION SCIENCES & ENGINEERING Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Root characteristics like length, diameter and volume are critical to measure to understand plant and soil functions. RhizoVision Explorer is an open-source software designed to enable researchers interested in roots by providing an easy-to-use interface, fast image processing and reliable measurements. The default broken roots mode is intended for roots sampled from pots and soil cores, washed and typically scanned on a flatbed scanner, and provides measurements like length, diameter and volume. The optional whole root mode for complete root systems or root crowns provides additional measurements such as angles, root depth and convex hull. Both modes support providing measurements grouped by defined diameter ranges, the inclusion of multiple regions of interest and batch analysis. RhizoVision Explorer was successfully validated against ground truth data using a new copper wire image set. In comparison, the current reference software, the commercial WinRhizo (TM), drastically underestimated volume when wires of different diameters were in the same image. Additionally, measurements were compared with WinRhizo (TM) and IJ_Rhizo using a simulated root image set, showing general agreement in software measurements, except for root volume. Finally, scanned root image sets acquired in different labs for the crop, herbaceous and tree species were used to compare results from RhizoVision Explorer with WinRhizo (TM). The two software showed general agreement, except that WinRhizo (TM) substantially underestimated root volume relative to RhizoVision Explorer. In the current context of rapidly growing interest in root science, RhizoVision Explorer intends to become a reference software, improve the overall accuracy and replicability of root trait measurements and provide a foundation for collaborative improvement and reliable access to all.","2021-09-13","2025-04-25 16:49:05","2025-04-25 16:49:05","","","","6","13","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","Ground truth; phenomics; phenotyping; rhizosphere; root system architecture; traits","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Design/methodology/approach - Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. Findings - There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and “tribal knowledge” that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. Originality/value - The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 16:49:05","2025-04-25 16:49:05","","211-223","","2","28","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LIMITED Type: Article","","","","Software tools; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To observe these relationships, we conducted a hypothesis-testing questionnaire-type survey involving 200 software development experts and professionals working at 60 multinational COSS companies. Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model. Therefore, COSS companies may need to prioritize software quality as it is the most critical variable impacting the success of COSS companies.","2022","2025-04-25 16:49:05","2025-04-25 16:49:05","","46490-46503","","","10","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","Open source software; Software; software quality; Companies; Knowledge management; Software quality; Commercial open-source software; company success; Integrated circuits; intellectual capital; Knowledge based systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While there has been prior work on identifying key individuals in open source development, little attention has been devoted to the identification of cross-cutting core individuals (boundary spanners) whose responsibilities span across different functional areas of open source development (e.g., who are involved both in development-centric activities and user-centric activities). To address this gap, we propose an approach to identify the core cross-cutting members and their roles within the community through analyzing email communication repositories. We use Social Network Analysis (SNA) tools to identify the most active core members in different forums (that have different focus such as Python-dev that focuses on language evolution and Python Lists that focus on user support), and their activities over time, thus identifying the core developers and their involvement in different community mailing lists. Based on the involvement of a core developer and the overall social structure of the network of core developers, we also present an approach for identifying a potential replacement for a community administrator that steps down.

Including function points and its variants, there are several size measures and corresponding measurement methods that can be used for effort estimation. However, in most of the projects, there is limited amount of information available in the early stages and significant effort is spent for size measurement and effort estimation with such methods. This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software. For this purpose, we consider open source project management and game software. We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., conceptual) and solution domain (i.e., design) models. The results reveal a high correlation between the number of conceptual classes in the problem domain model and the number of software classes constituting the corresponding software. The results suggest that it is possible to use problem domain descriptions in the early stages of software development projects to make plausible predictions for the size of the software.","2014","2025-04-25 16:49:06","2025-04-25 16:49:06","","81-84","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","conceptual models; linear regression model for size estimation; size estimation","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.","2011","2025-04-25 16:49:06","2025-04-25 16:49:06","","88-122","","1","12","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper describes a software development process that has proven vital to the success of the widely used open-source toolkits ITK (itk.org) and VTK (vtk.org). This process facilitates cross-platform development, includes automatic documentation generation, integrates continuous testing, and posts the results of the process on publicly accessible web pages. The net result is that a responsive feedback loop is created between the developers in the community and automated processes to measure software quality. With this process software converges towards better software as long as the process is enforced.

Based on the authors' experiences as graduate students and coding instructors, this paper provides a unique overview of the obstacles that graduate students face in obtaining the knowledge and skills required to complete their research and in transitioning from an OSS user to a contributor: psychological, practical, and cultural barriers and challenges specific to graduate students including cognitive load in graduate school, the importance of a knowledgeable mentor, seeking help from both the online and local communities, and the ongoing campaign to recognize software as research output in career and degree progression. Specific and practical steps are recommended to provide a foundation for graduate students, supervisors, administrators, and members of the OSS community to help overcome these obstacles. In conclusion, the objective of these recommendations is to describe a possible framework that individuals from across the scientific community can adapt to their needs and facilitate a sustainable feedback loop between graduate students and OSS.","2020-05-07","2025-04-25 16:49:06","2025-04-25 16:49:06","","289-303","","","5","","","","","","","","","","English","","","","","","","Place: 65 AURIGA DR, SUITE 203, OTTAWA, ON K2E 7W6, CANADA Publisher: CANADIAN SCIENCE PUBLISHING Type: Article","","","","open-source software; academic culture; computational research; graduate students","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Dolores; Bueno, Salvador","ORGANIZATIONAL AND MOTIVATIONAL FACTORS FOR IMPLEMENTING ENTERPRISE SOLUTIONS BASED ON OPEN SOURCE SOFTWARE","RELATIONAL DATABASES AND OPEN-SOURCE SOFTWARE DEVELOPMENTS","978-1-61668-436-5","","","","Organizations implement Enterprise solutions, mainly Enterprise Resource Planning (ERP) systems, with the aim of attaining operational efficiency and the incorporation into new markets through the real time information flow control of the entire organization. However, ERP systems are complex tools, particularly for small and medium size enterprises (SMEs). For this reason, new ERP configurations have arisen, such as Open Source Software-ERP (OSS-ERP). In the website Sourceforge.net, we can identify 2058 projects about OSS-ERP, although all of them have not had an impact on the ERP market. This data is indicative of the increasing relevance of this enterprise solution for organizations. At this moment, the OSS-ERP vendors with a greater diffusion are Compiere, Openbravo, Abanq (previously FacturaLux), ERP5, Tiny ERP, Fisterra, OFBiz, SQL-Ledger and WebERP. OSS-ERP has three relevant advantages for organizations: (1) increased adaptability, (2) decreased reliance on a single supplier, (3) reduced costs. OSS-ERP generally include the necessary functions to integrally manage all the activities of a company. Due to their high flexibility, these tools can be adapted to the client's specific needs. Furthermore, as OSS-ERP are based on open software technologies, organizations do not have to pay licenses or exclusive contracts. With the collaboration of partners, OSS-ERP vendors receive benefits for the support services. Research in OSS has identified individual personal motives for using OSS software, analyzing specific OSS solutions, or the OSS movement itself. The literature in Enterprise solutions has also analyzed the main organizational factors for successfully implementing an ERP system. However, OSS-ERP is a research topic barely analyzed by the literature. This paper's aim is to specifically focus on the organizational and motivational factors for implementing OSS-ERP. The authors developed a research work for testing the impact of organizational and motivational factors on the implementation of OSS-ERP by means of a survey of organizations with OSS-ERP and OSS-ERP users.","2010","2025-04-25 16:49:06","2025-04-25 16:49:06","","257-273","","","","","","","Computer Science Technology and Applications","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Taylor, JR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A total number of 179 responses were used for data analysis. Findings From the survey, the authors identify significant barriers and drivers that US academic libraries may consider before adopting OSS and found that awareness itself is not a barrier. While about half of respondents confirmed using OSS, the authors found surprisingly low levels of intent to adopt from current non-adopters. Practical implications - This research offers insights for promoting OSS adoption. Also, it provides funding agencies and administrators with guidelines to encourage successful deployment of OSS in higher education.

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers' positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-07","2025-04-25 16:49:06","2025-04-25 16:49:06","","","","4","32","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","hierarchy; developer networks; Open-source software projects; organizational structure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to meet user needs and functional changes, open-source software continuously improves its software quality through successive releases. Due to the iterative development process of open-source software, open-source software testing also requires continuous learning to understand the changes in the software. Therefore, the fault detection process of open-source software involves a learning process. Additionally, the complexity and uncertainty of the open-source software development process also lead to stochastically introduced faults when troubleshooting in the open-source software debugging process. Considering the phenomenon of learning factors and the random introduction of faults during the testing process of open-source software, this paper proposes a reliability modeling method for open-source software that considers learning factors and the random introduction of faults. Least square estimation and maximal likelihood estimation are used to determine the model parameters. Four fault data sets from Apache open-source software projects are used to compare the model performances. Experimental results indicate that the proposed model is superior to other models. The proposed model can accurately predict the number of remaining faults in the open-source software and be used for actual open-source software reliability evaluation.","2024-01","2025-04-25 16:49:06","2025-04-25 16:49:06","","","","2","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source software; learning factors; software reliability model; stochastic differential equation; stochastically introduced faults","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many projects leverage the contribution of outsiders, and the sustainability of the project relies on retaining some of these newcomers. This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review; (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects; (iii) 24 responses to a questionnaire sent to 9 OSS projects; and (iv) semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practitioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteristics, reception issues, orientation, technical hurdles, and documentation problems. We could observe recurrent barriers evidenced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-25 16:49:06","2025-04-25 16:49:06","","51+","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Univ Fed Alagoas; Ufal; CAPES; Conselho Nacl Desenvolvimento Cientifico & Tecnologico; Ines; Google; Inst Fed Alagoas; Aloo Telecom; Alagoas Governo Estado, Secretaria Estado Turismo; Maceio Convent & Visitors Bur; Soc Brasileira Computacao; Josi Mendes Consultoria & Eventos; Transamerica Turismo; IEEE Comp Soc Type: Proceedings Paper","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 16:49:06","2025-04-25 16:49:06","","156-187","","2","25","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Open source software; Open source; Diffusion; Case studies; Adoption; Diffusion theory; Public sector organizations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context. We conclude by discussing governance issues related to the disciplined use and reuse of open source and areas for further improvements.","2022","2025-04-25 16:49:06","2025-04-25 16:49:06","","154-163","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Siemens; Pure Syst; Assoc Comp Machin; Graz Univ Tech; Itk Engn; Combeenation; Select Arts; Stream Diver; Hitec; Stadt Graz.at; Elsevier Journal Syst & Software Type: Proceedings Paper","","","","open source software; dependencies; NPM; DevSecOps; Maven","","Felfernig, A; Fuentes, L; Cleland-Huang, J; Assuncao, WKG; Falkner, A; Azanza, M; Luaces, MAR; Bhushan, M; Semini, L; Devroey, X; Werner, CML; Seidl, C; Le, VM; Horcas, JM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study aimed to develop a population PK model for vancomycin using Korean data to improve the quality of TDM for Korean patients. A total of 220 patients (1020 observations) who received vancomycin TDM services were included in the dataset. A population PK analysis was performed using non-linear mixed effects modeling, and a covariate evaluation was conducted. A two-compartment model with first-order elimination best explained the vancomycin PK, with estimates of 2.82 L/h, 31.8 L, 11.7 L/h, and 75.4 L for CL, V-1, Q, and V-2, respectively. In the covariate analysis, weight correlated with the volume of the peripheral compartment, and creatinine clearance, hemodialysis, and continuous renal replacement therapy treatments contributed to the clearance of vancomycin. The results show the clear need to optimize the PK parameters used for TDM in Korean patients. Specifically, V-1 should be smaller for Korean patients, and renal replacement therapies should be considered in TDM practice. This final model was successfully applied in R shiny as open-source software for Koreans.","2019-05","2025-04-25 16:49:07","2025-04-25 16:49:07","","","","5","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","open-source software; Korean; population pharmacokinetics; therapeutic drug management; vancomycin","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects. We provide a comparison of the two Apache review techniques as well as a comparison of Apache review to inspection in an industrial project. We conclude that Apache reviews can be described as (1) early, frequent reviews (2) of small, independent, complete contributions (3) conducted asynchronously by a potentially large, but actually small, group of self-selected experts (4) leading to an efficient and effective peer review technique.","2008","2025-04-25 16:49:07","2025-04-25 16:49:07","","541-550","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1515 BROADWAY, NEW YORK, NY 10036-9998 USA","English","","","","","","","Backup Publisher: ACM SIGSOFT; IEEE CSE; Univ Paderborn; Univ Leipzig; SIEMENS; Zuhlke; Adesso; Deutsch Telekom Labs; sd&m; Werum; Microsoft Res; IBM; i nemis; dSPACE Type: Proceedings Paper","","","","Open source software; Peer review; Inspection; Mining software repositories (email)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use Of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are also likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization, that naturally fix themselves during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-25 16:49:07","2025-04-25 16:49:07","","97-106","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc, Tech Comm Fault Tolerant Comp; IFIP Working Grp 10 4 Dependable Comp & Fault Tolerance; AT&T; Lucent Technologies; Compaq Comp Corp; Georgia Inst Technol; IBM Corp; LAAS CNRS; Microsoft Corp Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conduct an explorative case study at Siemens AG. Siemens introduced a formal template process which can be adapted by the organizational units according to their demands.

It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects.","2024-05","2025-04-25 16:49:07","2025-04-25 16:49:07","","","","5","36","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","software evolution; assessment model; open source software engineering; software resilience","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We empirically investigate different types of conflict in Free and Open Source Software development teams, their antecedents and impact on developers' sustained participation. Following a survey of 222 FOSS developers, we find conflict to have an overall negative effect on developer retention. Furthermore, different types of conflict have varying impact on outcomes. In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes. Though we find structural factors like task interdependence and geographical distribution increase overall conflict levels in FOSS teams, participatory decision-making and a transformational leadership style have an ameliorating effect.

The study investigates factors that affect the selection of software for public sector information systems with, an emphasis on how Free and Open Source Software ( FOSS) is used and could be used in such projects. The objectives of the study are as follows. The study aims to identify factors that affect the adoption of Software in Sri Lankan government sector projects. In addition to this it identifies features that are considered as important in such large Information Systems, and how they relate to Open Source Software adoption in the context of the public sector in Sri Lanka. The findings are analyzed and suitable recommendations are presented for better selection of software in the public sector. The work is important as it identifies and highlights factors that affect the choice of software in the public sector. This is important for several categories of people. It is of importance to the strategic management and policy makers to know what drives the information system procurement decisions in order to make more relevant policies and guidelines that are congruent with the needs in government sector departments. It is useful when advocating new technologies and information systems. This is especially true when advocating the use of Free and Open Source software for the use in the public sector in a wholesome and sustainable manner. The research is also important to software vendors and solution providers to the public sector in identifying what factors need to be taken in to account when bidding for public sector IS projects. The research is of a qualitative nature. It consists of multiple case studies of selected government sector departments and projects in Sri Lanka. The study investigates information systems developed by internal staff, developed by external consultants, procured systems, system implementation via private public partnerships (PPP) and projects guided by the Information and Communication Technology Agency (ICTA) of Sri Lanka. Data was gathered through interviews of staff at different levels of selected government sector Information Systems projects. The data was comparatively analyzed on a case by case basis to identify common patterns and trends among the investigated organizations and projects. The identified factors affecting the choice of software include the cost, technical specifications, bidder's expertise in selected technology and user's expertise in selected technology amongst other factors described in the full paper.

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 16:49:07","2025-04-25 16:49:07","","1439-1458","","3","44","","","","","","","","","","English","","","","","","","Place: UNIV MINNESOTA-SCH MANAGEMENT 271 19TH AVE SOUTH, MINNEAPOLIS, MN 55455 USA Publisher: SOC INFORM MANAGE-MIS RES CENT Type: Article","","","","Open source software; product quality; signaling; takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We empirically studied the impacts of two social influence mechanisms-word-of-mouth (WOM) and observational learning (OL)-on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.","2021-09","2025-04-25 16:49:07","2025-04-25 16:49:07","","1133-1147","","9","72","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, integrating external and internal sources of social capital is challenging and identifying appropriate integration strategies is crucial for the success of such endeavors. This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success.

Abstractions of MPL systems are derived as finite-state transition systems. A transition system is obtained first by partitioning the state space of the MPL system into finitely many regions and then by associating a unique state of the transition system to each partitioning region. Relations among the states of the transition system are then set up based on the underlying dynamical transitions between the corresponding partitioning regions of the MPL state space. In order to establish formal equivalences, the obtained finite abstractions are proven either to simulate or to bisimulate the original MPL system. The approach enables the study of general properties of the original MPL system formalized as logical specifications, by verifying them over the finite abstraction via model checking. The article presents a new, extended and improved implementation of a software tool (available online) for the discussed formal abstraction of MPL systems, and is tested on a numerical benchmark against a previous version.","2016-03","2025-04-25 16:49:08","2025-04-25 16:49:08","","109-145","","1, SI","26","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Bisimulations; Difference-bound matrices; Discrete-event systems; Max-plus algebra; Model abstractions; Model checking; Piece-wise affine systems; Transition systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from ultra-high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically.

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 7 0 0; 0 0 0 bug reports obtained from the BUGZILLA installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3% with an associated recall of 38.9%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.","2013","2025-04-25 16:49:08","2025-04-25 16:49:08","","1032-1041","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM Special Interest Grp Software Engn; IEEE Comp Soc; Tech Council Software Engn Type: Proceedings Paper","","","","","","Notkin, D; Cheng, BHC; Pohl, K","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is time-consuming because of the bioinformatics processes involved, including sequence trimming, consensus sequence generation, and public database searches. We developed a simple and fully automated software that enabled species-level identification of NTM from trace files, SnackNTM (https://github.com/Young-gonKim/SnackNTM). Methods: JAVA programing language was used for software development. The SnackNTM diagnostic algorithm utilized 16S rRNA gene sequences, according to the Clinical & Laboratory Standards Institute guidelines, and an rpoB gene region was adjunctively utilized to narrow down the species. The software performance was validated using trace files of 234 clinical cases, comprising 217 consecutive cases and 17 additionally selected cases of unique species. Results: SnackNTM could analyze multiple cases at once, and all the bioinformatics processes required for sequence-based NTM identification were automatically performed with a single mouse click. SnackNTM successfully identified 95.9% (208/217) of consecutive clinical cases, and the results showed 99.0% (206/208) agreement with manual classification results. SnackNTM successfully identified all 17 cases of unique species. In a processing time comparison test, the analysis and reporting of 30 cases, which took 150 minutes manually, took only 40 minutes with SnackNTM. Conclusions: SnackNTM is expected to reduce the workload for NTM identification, especially in clinical laboratories that process large numbers of cases.","2022-03","2025-04-25 16:49:08","2025-04-25 16:49:08","","213-248","","2","42","","","","","","","","","","English","","","","","","","Place: A505-ASTERIUM SEOUL, 372 HANGANG-DAERO, YONGSAN-GU, SEOUL, 04323, SOUTH KOREA Publisher: KOREAN SOC LABORATORY MEDICINE Type: Article","","","","16S rRNA gene; Nontuberculous mycobacteria; NTM identification; rpoB; SnackNTM","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. Conclusion: We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care. (C) 2009 Elsevier Ireland Ltd.

For over a decade, the digital communities around the globe have used FOSS packages not only as an inexpensive way to access to information available on Internet, but also to disseminate thoughts, opinions and concerns about various socio-political and economic matters. Proxy servers and FOSS played a vital role in helping citizens in repressed countries to bypass the state imposed Internet content filtering and censorship practices. On the one hand, proxy servers act as redirectors to websites, and on the other hand, many of these servers are the main source for downloading FOSS anti-filtering software packages. These packages can provide secure web surfing via anonymous web access, data encryption. IP address masking, location concealment, browser history and cookie clean-ups but they also provide proxy software updates as well as domain name updates. The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In particular, they are poorly adapted to the slow Internet connections in many developing countries such as Iran. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.

Objective: This work is aimed at studying the communication functions of bug comments and their associations with fast and complete bug fixing in OSS development. Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist. The results of this work could be used to improve corrective tasks in OSS development and some other specific linguistic aspects should be studied in detail in OSS communities.","2021-08","2025-04-25 16:49:08","2025-04-25 16:49:08","","","","","136","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Machine learning; Bug fixing; Communication function; Corrective maintenance; Issue Tracking System; Open Source Software development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity. (C) 2019 The Authors.

This phenomenon is also known as “Inner Source”. While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. Objective: The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Method: Following an initial systematic literature review to generate seed category data constructs, we performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques. Results: We have identified a number of challenges and approaches to address them, and compared the findings to challenges related to development with OSS products reported in the literature. We found that many challenges identified in the case study could be mapped to challenges related to integration of OSS. Conclusion: The results provide important insights into common challenges of developing with OSS and Inner Source and may help organizations to understand how to improve their software development practices by adopting certain OSSD practices. The findings also identify the areas that need further research. (C) 2011 Elsevier B.V.

Here we describe the Brain Modeling ToolKit (BMTK), a software suite for building models and performing simulations at multiple levels of resolution, from biophysically detailed multi-compartmental, to point-neuron, to population-statistical approaches. Leveraging the SONATA file format and existing software such as NEURON, NEST, and others, BMTK offers a consistent user experience across multiple levels of resolution. It permits highly sophisticated simulations to be set up with little coding required, thus lowering entry barriers to new users. We illustrate successful applications of BMTK to large-scale simulations of a cortical area. BMTK is an open-source package provided as a resource supporting modeling-based discovery in the community.","2020-11","2025-04-25 16:49:09","2025-04-25 16:49:09","","","","11","16","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications. By our plug-in, information about measured physiological processes can be obtained and transferred into clinical practice.","2013-04","2025-04-25 16:49:09","2025-04-25 16:49:09","","344-352","","2","26","","","","","","","","","","English","","","","","","","Place: 233 SPRING ST, NEW YORK, NY 10013 USA Publisher: SPRINGER Type: Article","","","","Algorithms; Image processing; Computer-assisted; Magnetic resonance imaging; Perfusion","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields.

In many Open Source Softoware Development (OSSD) communities, DM processes lie buried amongst vast amounts of publicly available data. Hidden within this data lie the rationale for decisions that led to the evolution and maintenance of software products. While there have been some efforts to extract DM processes from publicly available data, the rationale behind `boo' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million mails. This paper makes two main contributions. First. it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second. it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven. bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement).

To estimate whether a state ofsocio-technical congruenceis achieved, which is associated with software quality and project success, we assess the alignment of collaboration and communication in such software projects in terms ofcoordination requirements. By means of an empirical study on a substantial set of large-scale open-source software projects-the development histories of all projects sum up to over 180 years-we aim at shedding light on this issue. To this end, to take a more semantic view on this phenomenon in comparison to previous work, we do not only identify coordination requirements arising from files and functions only, but also those arising from features. We found that open-source developers fulfill coordination requirements intentionally, but mostly those coordination requirements that arise from coupled source-code artifacts, while they resolve simpler ones independently. Furthermore, neither of the considered abstraction levels of source-code artifacts (files, functions, features) is more suitable to construct coordination requirements with respect to their fulfillment. This finding strongly indicates that features do not play an as important role in the development process as expected and commonly believed by the research community in the area of feature-oriented and feature-driven development. Finally, we identified notable evolutionary trends in the fulfillment of coordination requirements and showed that far-reaching social events (such as organizational issues) have a huge impact on their fulfillment, both negatively and positively. The key findings of our empirical study are that socio-technical relations are important to understand open-source development communities and that the incorporation of different abstraction levels for developer collaboration does yield important insights to further improve the evolution in open-source software projects.","2020-11","2025-04-25 16:49:09","2025-04-25 16:49:09","","4379-4426","","6","25","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Socio-technical congruence; Codeface; Configurable systems; Coordination requirements; Coronet; Feature-oriented software development; Features; Open-source software systems; Social-network analysis; Software product lines","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using survey data from 574 GitHub developers, we tested a model to examine the impact of Person-Organization fit and psychological ownership on developers' turnover intentions.

This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 %, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 %. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic. These insights provide various stakeholders, including individuals, organizations, and policymakers, with vital knowledge to prepare for future disruptions, foster sustainable resilience, and adeptly navigate the evolving landscape of remote work in a postpandemic world.","2023-12","2025-04-25 16:49:09","2025-04-25 16:49:09","","","","10","52","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source software; COVID-19; Face-to-face interactions; Lockdown; Work productivity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although it is well-known that OSS contributors have different involvements (e.g., while some developers drive the project, there is a long tail of peripheral developers), little is known about how the contributor's degree of participation can influence the build status of an OSS project. Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result. Our results suggest that there is no representative difference between their build success (they are similar in 85% of the analyzed projects), meaning that being a casual contributor is not a strong indicator for creating failing builds. Also, factors like the size of their contributions and the number of project configurations (jobs) have the potential of impacting the build success.","2017","2025-04-25 16:49:09","2025-04-25 16:49:09","","475-478","","","","","","","IEEE International Working Conference on Mining Software Repositories","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISSN: 2160-1852 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when “simple stupid bugs” were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub. Leveraging a statistical survival model and other non-parametric statistical tests, we found that there were two main categories of categorical variables that affect a bug's life; Time Factors and Author Factors. We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time. These findings will provide vital insight to help the open-source community mitigate the abundance of code and can be used in future research to aid in bug-finding programs.","2023-03","2025-04-25 16:49:09","2025-04-25 16:49:09","","","","5","13","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","survival analysis; bug fixes; one-line bugs; statistical analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

EBA involves the use of psychometric instruments to gather data that can inform clinical decision-making, inform policymakers, and serve as a basis for research and quality management. Despite its potential, EBA is often hindered by barriers such as workload and cost, leading to its underutilization. Regarding low- and middle-income countries (LMIC), the implementation of EBA is recognized as a key strategy to address and close the prevalent mental health treatment gap.To simplify the application of EBA including in LMIC, an international team of researchers and practitioners from Tanzania, Kosovo, Chile, and Switzerland developed the Mental Health Information Reporting Assistant (MHIRA). MHIRA is an open-source electronic health record that streamlines EBA by digitising psychometric instruments and organising patient data in a user-friendly manner. It provides immediate and convenient reports to inform clinical decision-making.The current article provides a comprehensive overview of the features and technical details of MHIRA, as well as insights from four implementation scenarios. The experience gained during the implementations as well as the user-feedback suggests that MHIRA has the potential to be successfully implemented in a variety of clinical contexts and simplify the use of EBA. However, further research is necessary to establish its potential to sustainably transform healthcare services and impact patient outcomes.In conclusion, MHIRA represents an important step in promoting the widespread adoption of EBA in mental health. It offers a promising solution to the barriers that have limited the use of EBA in the past and holds the potential to improve patient outcomes and support the ongoing efforts to address gaps in mental health care.","2023-10-02","2025-04-25 16:49:10","2025-04-25 16:49:10","","","","1","23","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Software; Open-source; Digital; Electronic health record; Evidence-based assessment; Implementation sciences; Low- and middle-income countries; Mental health","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, these infrequent volunteers contribute to the sustainability of FLOSS projects, and should ideally be encouraged to continue participating, even if they cannot be persuaded to contribute regularly. Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature. Also, episodic volunteers make a wide range of value-added contributions other than code, and they should neither be expected nor coerced into becoming habitual volunteers.","2020-09-01","2025-04-25 16:49:10","2025-04-25 16:49:10","","962-980","","9","46","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","Open source software; free software; open source software; Task analysis; Community management; Companies; Sustainable development; Lenses; episodic volunteering; peripheral developer","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities. (C) 2013 The Authors. Published by Elsevier Inc.

Although some of the hosted projects are growing and have many developers, most projects are organized by a few developers and face difficulties in terms of sustainability. OSS projects depend mainly on volunteer developers, and attracting and retaining these volunteers are major concerns of the project stakeholders. To investigate the population structures of OSS development communities in detail and conduct software analytics to obtain actionable information, we apply a demographic approach. Demography is the scientific study of population and seeks to identify the levels and trends in the size and components of a population. This paper presents a case study, investigating the characteristics of the population structures of OSS projects on GitHub, and shows population projections generated with the well-known cohort component method. We found that there are four types of population structures in OSS development communities in terms of experiences and contributions. In addition, we projected the future population accurately using a cohort component population projection method. This method predicts a population of the next period using a survival rate calculated from past population. To the best of our knowledge, this is the first study that applied demography to the field of OSS research. Our approach addressing OSS-related problems based on demography will bring new insights, since studying population is novel in OSS research. Understanding current and future structures of OSS projects can help practitioners to monitor a project, gain awareness of what is happening, manage risks, and evaluate past decisions.","2016-05","2025-04-25 16:49:10","2025-04-25 16:49:10","","1304-1315","","5","E99D","","","","","","","","","","English","","","","","","","Place: KIKAI-SHINKO-KAIKAN BLDG, 3-5-8, SHIBA-KOEN, MINATO-KU, TOKYO, 105-0011, JAPAN Publisher: IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG Type: Article","","","","OSS; demography; software development communities; software population pyramids","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The gains obtained from the reuse of community-developed libraries may be offset by the cost of detecting, assessing, and mitigating their vulnerabilities in a timely manner. In this paper we present a novel method to detect, assess and mitigate OSS vulnerabilities that improves on state-of-the-art approaches, which commonly depend on metadata to identify vulnerable OSS dependencies. Our solution instead is code-centric and combines static and dynamic analysis to determine the reachability of the vulnerable portion of libraries used (directly or transitively) by an application. Taking this usage into account, our approach then supports developers in choosing among the existing non-vulnerable library versions. Vulas, the tool implementing our code-centric and usage-based approach, is officially recommended by SAP to scan its Java software, and has been successfully used to perform more than 250000 scans of about 500 applications since December 2016.

For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.","2010","2025-04-25 16:49:10","2025-04-25 16:49:10","","","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","ISSN: 1063-6773 Type: Proceedings Paper","","","","software metrics; software quality; open-source software; Software maintenance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, even after 20 years of intense research in this field, perfusion imaging still remains a research tool without a broad clinical usage. One problem is the lack of standardization in technical aspects which have to be considered for successful quantitative evaluation; the second problem is a lack of tools that allow a direct integration into the diagnostic workflow in radiology. Results: Five compartment models, namely, a one compartment model (1CP), a two compartment exchange (2CXM), a two compartment uptake model (2CUM), a two compartment filtration model (2FM) and eventually the extended Toft's model (ETM) were implemented as plugin for the DICOM workstation OsiriX. Moreover, the plugin has a clean graphical user interface and provides means for quality management during the perfusion data analysis. Based on reference test data, the implementation was validated against a reference implementation. No differences were found in the calculated parameters. Conclusion: We developed open source software to analyse DCE-MRI perfusion data. The software is designed as plugin for the DICOM Workstation OsiriX. It features a clean GUI and provides a simple workflow for data analysis while it could also be seen as a toolbox providing an implementation of several recent compartment models to be applied in research tasks. Integration into the infrastructure of a radiology department is given via OsiriX. Results can be saved automatically and reports generated automatically during data analysis ensure certain quality control.","2016-01-14","2025-04-25 16:49:10","2025-04-25 16:49:10","","","","","16","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Open source software; Data analysis; Workflow; Compartment models; Dce-mri","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We compare group maintenance behaviors between both core and peripheral members of these groups, as well as behaviors between a group that remains producing software today and one which has since dissolved.

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for-profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 16:49:10","2025-04-25 16:49:10","","369-402","","2","30","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","software development; open source software; metaphor; postcolonialism; Third Design Space; third space","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Due to their cell-mimicking properties, GUITs have become a widespread experimental tool in synthetic biology to study membrane properties and cellular processes. In stark contrast to the experimental progress, quantitative analysis of GUV microscopy images has received much less attention. Currently, most analysis is performed either manually or with custom-made scripts, which makes analysis time-consuming and results difficult to compare across studies. To make quantitative GUV analysis accessible and fast, we present DisGUVery, an open-source, versatile software that encapsulates multiple algorithms for automated detection and analysis of GUVs in microscopy images. With a performance analysis, we demonstrate that DisGUVery's three vesicle detection modules successfully identify GUVs in images obtained with a wide range of imaging sources, in various typical GUV experiments. Multiple predefined analysis modules allow the user to extract properties such as membrane fluorescence, veside shape, and internal fluorescence from large populations. A new membrane segmentation algorithm facilitates spatial fluorescence analysis of nonspherical vesicles. Altogether, DisGUVery provides an accessible tool to enable high-throughput automated analysis of GUVs, and thereby to promote quantitative data analysis in synthetic cell research.","2023-01-20","2025-04-25 16:49:10","2025-04-25 16:49:10","","120-135","","1","12","","","","","","","","","","English","","","","","","","Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC Type: Article","","","","open-source software; bottom-up reconstitution; giant unilamellar vesicles; image analysis; object detection; synthetic cell","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm's practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems. (C) 2017 The Authors.

Mentoring allows contributors to improve their technical skills and learn about the protocols and cultural norms of the project. However, mentoring has its challenges: mentors sometimes feel unappreciated, and mentees may have mismatched interests or lack interpersonal skills. Existing research has investigated the different challenges of mentoring in different OSS contexts, but we lack a holistic understanding. Objective: A comprehensive understanding of the current practices and challenges of mentoring in OSS is needed to implement appropriate strategies to facilitate mentoring. Method: This study presents a systematic literature review investigating how literature has characterized mentoring practices in OSS, including their challenges and the strategies to mitigate them. We retrieved 232 studies from four digital libraries. Out of these, 21 were primary studies. Using this, we performed backward and author snowballing, adding another 27 studies. We conducted a completeness check by reviewing the references of the 4 most relevant primary studies, which resulted in us adding 1 additional study. We then conducted a full-text review and evaluated the studies using a set of criteria; as a result, 10 papers were excluded. We then employed an open-coding approach to analyze, aggregate, and synthesize the selected studies. Results: We reviewed 39 studies to investigate the different facets of mentoring in OSS, encompassing motivations, goals, channels, and contributor dynamics. We then identified 13 challenges associated with mentoring in OSS, which fall into three categories: social, process, and technical. We also present a quick-reference strategy catalog to map these strategies to challenges for mitigation. Conclusions: Our study serves as a guideline for researchers and practitioners about mentoring challenges and potential strategies to mitigate these challenges.","2024-07","2025-04-25 16:49:10","2025-04-25 16:49:10","","","","","171","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Open source; Mentoring; Literature review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.","2021-09-25","2025-04-25 16:49:11","2025-04-25 16:49:11","","","","1","13","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Deep learning; De novo drug design; Graphical user interface; Molecule generation; Web application","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially influence how a new OSS project chooses among such licenses and how the experiences of the project manager of a new OSS project with particular licenses affects its susceptibility to this social influence. We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Our results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its inter-project social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. We also find that managers of new projects who have been members of more successful prior OSS projects and who have greater depth and diversity, of experience in the OSS community are less susceptible to social influence. Finally, we find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license. These results have implications for research on innovation adoption and diffusion, open source software licensing, and the governance of economic exchange.","2013-09","2025-04-25 16:49:11","2025-04-25 16:49:11","","539-560","","3","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","social networks; social influence; innovation adoption and diffusion; open source software license","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A world where internet is a medium to access mass information. So, MOOC is the one way of learning in this digital social network world. MOOC is a course-Open, Participatory, Distributed and Lifelong networked learning. It has facility of various courses, with start, end dates and participants. It's a way to connect and collaborate while developing digital skills an engage in a learning process. It is an EVENT around which people who care about a topic can gather and talk about it in a structured way. MOOC can promote the network learning for lifelong. People that have reputations for interesting skills and innovative thinking besides a topic, collaborate by opening an online course covering that topic. Anyone can join it. In a MOOC we can choose what we want to do, how we want to participate and we can decide if we have been successful, just like an existing atmosphere.

By knowing this licensing effect through scientific publications and their experience, project managers became able to act strategically, loosening up the restrictions associated with their source code due to sponsor interests, for example; or the contrary, tightening restrictions up to guarantee source code openness, adhering to the “forever free” strategy. But, have project managers behaved strategically like that, changing their projects license? Up to this paper, we did not know if and what types of changes in these legal allowances project managers have made and, more importantly, whether such managerial interventions are associated with variations in intervened project attractiveness (i.e., related to their numbers of web hits, downloads and members). This paper accomplishes these two goals and demonstrates that: 1) managers of free and open source software projects do change the distribution rights of their source code through a change in the (group of) license(s) adopted; and 2) variations in attractiveness are associated with the strategic choice of a licensing schema. To reach these conclusions, a unique dataset of open source projects that have changed license was assembled in a comparative form, analyzing intervened projects over its monthly periods of different licenses. Based on a sample of more than 3500 active projects over 44 months obtained from the FLOSSmole repository of Sourceforge.net, 756 projects that had changed their source code distribution allowances and restrictions were identified and analyzed. A dataset on these projects' type of changes was assembled to enable a descriptive and exploratory analysis of the types of license interventions observed over a period of almost four years anchored on projects' attractiveness. More than 35 types of interventions were detected. The results indicate that variations in attractiveness after a license intervention are not symmetric; that is, if a change from license schema A to B is beneficial to attractiveness, a change from B to A is not necessarily prejudicial. This and other interesting findings are discussed in detail. In general, the results here reported support the current literature knowledge that the restrictions imposed by the license on the source code distribution are associated with market success vis-a-vis project attractiveness, but they also suggest that the state-of-the-science is superficial in terms of what is known about why these differences in attractiveness can be observed. The complexity of the results indicates to free software managers that no licensing schema should be seen as the right one, and its choice should be carefully made, considering project strategic goals as perceived relevant to stakeholders of the application and its production. These conclusions create awareness of several limitations of our current knowledge, which are discussed along with guidelines to understand them deeper in future research endeavors.","2017-08-07","2025-04-25 16:49:11","2025-04-25 16:49:11","","","","","8","","","","","","","","","","English","","","","","","","Place: Av.

This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness.

Design/methodology/approach This study focuses on dependencies using three network metrics - degree centrality, betweenness centrality and closeness centrality - in developer and module networks. A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks. Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.

The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the “institutional design” of the ASF could aid in producing the OSS public good by providing services that projects require.","2022","2025-04-25 16:49:12","2025-04-25 16:49:12","","64-77","","1","16","","","","","","","","","","English","","","","","","","Place: Unit 3N, 6 Osborn Street, LONDON, E1 6TD, ENGLAND Publisher: UBIQUITY PRESS LTD Type: Article","","","","institutional analysis; open source software; commons; public goods; cost-benefit analysis; common-pool resource; policy analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help “transfer” their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more “open” and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as “porting,” the “kernel,” “copyleft,” and “forking” that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.","2012","2025-04-25 16:49:12","2025-04-25 16:49:12","","234-243","","3","71","","","","","","","","","","English","","","","","","","Place: 3000 UNITED FOUNDERS BLVD, STE 148, OKLAHOMA CITY, OK 73112 USA Publisher: SOC APPLIED ANTHROPOLOGY Type: Article","","","","open source software; community-based natural resource management; transferability; watershed management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been in-stitutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous se-curity in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed secu-rity controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption en-ables businesses to deliver time-to-market security ready applications and services with accelerated ve-locity and sustainable agility in a cost-effective way.

The purpose of this paper is to analyse the teachers' motivation to contribute to OSS projects for teaching. A structural equation model (SEM) has been defined under the postulates of the Path-Goal leadership theory and Motivational Behaviour. This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader. Second, this study finds that motivating the participants of a project - teachers in this case - is highly recommended, in order to reach a successful adoption of OSS solutions for education.","2022-12-02","2025-04-25 16:49:12","2025-04-25 16:49:12","","1449-1463","","12","34","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","motivations; Open Source Software; leadership; teachers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a “safety net” for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and “living” design documentation. Rapid-cycle development or “agile” methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as “executable requirements.” Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the “executable requirements” are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.","2018-06","2025-04-25 16:49:12","2025-04-25 16:49:12","","80-90","","2","6","","","","","","","","","","English","","","","","","","Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC Type: Article","","","","agile methods; clinical decision support systems; electronic health records; software validation; software verification; test driven development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study. We reveal that Landsat 8 data combined with texture analysis can accurately detect these artificial landmarks across the heterogeneous environment of OROAFR; 75.68% of artificial water points within the site were successfully identified and false positive detection rate was minimal at 7.69%. The methodological framework developed for this work, based on the treatment of freely available satellite data using open source software, adds to other works attempting to help monitor threats to biodiversity in desert ecosystems, enabling up-to-date information on the level of anthropogenic activities in these habitats to be easily and regularly collected.","2015-10","2025-04-25 16:49:12","2025-04-25 16:49:12","","61-72","","1","1","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN, NJ 07030 USA Publisher: WILEY Type: Article","","","","open source; Anthropogenic activity; deserts; land use change; remote sensing; satellite data","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On these platforms, various information is obtained from developer activities that can then be used as developer metrics to solve a variety of challenges. In this study, we proposed new developer metrics extracted from the issue, commit, and pull request activities of developers on GitHub. We created developer metrics from the individual activities and combined certain activities according to some common traits. To evaluate these metrics, we created an item-based project recommendation system. In order to validate this system, we calculated the similarity score using two methods and assessed top-n hit scores using two different approaches. The results for all scores with these methods indicated that the most successful metrics were binary_issue_related, issue_commented, binary_pr_related, and issue_opened. To verify our results, we compared our metrics with another metric generated from a very similar study and found that most of our metrics gave better scores that metric. In conclusion, the issue feature is more crucial for GitHub compared with other features. Moreover, commenting activity in projects can be equally as valuable as code contributions. The most of binary metrics that were generated, regardless of the number of activities, also showed remarkable results.

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors (”problem solvers”) tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs (”problems”) tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between “core” and “peripheral” members identified exclusively on the basis of their individual level of contribution to the project.

Past work has focused on characterizing the main differences between OSS and traditional forms of software RE. In this effort we focus on differences in RE activity in OSS. RE is characterized as a socio-technical distributed cognitive (DCog) activity where multiple actors deploy artifacts to `compute' requirements. To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community. Finally the velocity of change in technological requirements influence the project's documentation practices of requirements with the level of design consistency desired in the end product influencing the decision-making channels used in the development endeavor.","2016","2025-04-25 16:49:13","2025-04-25 16:49:13","","4982-4991","","","","","","","Proceedings of the Annual Hawaii International Conference on System Sciences","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Pacific Res Inst Informat Syst & Management; Univ Hawaii Manoa, Shidler Coll Business, Dept IT Management; IBM; Provalis Res; Int Soc Serv Innovat Profess; Teradata; Univ Network; IEEE Comp Soc ISSN: 1060-3425 Type: Proceedings Paper","","","","","","Bui, TX; Sprague, RH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Chemical processes are invariably described by non-linear equations such as chemical reaction kinetics, flow-pressure relationships and physical properties. Dynamic simulation of such systems involves the solution of sets of non-linear differential and algebraic equations. There is also uncertainty associated with the model equations themselves (model uncertainty), their parameters (parametric uncertainty) and the inputs into the model (input uncertainty). Tools that aid chemical engineers in the solution of these problems have been successfully commercialised and enjoy a measure of success, although the adoption of dynamic and stochastic simulation packages is lagging behind the steady-state flowsheeting tools. Commercial software solutions can be prohibitively expensive in addition to confining users to adhere to proprietary standards. The Free Software and Open Source movements have made inroads into providing non-proprietary alternatives to many commercial software packages, which has encouraged the adoption of open standards. This work presents a framework for the development of stochastic dynamic simulations of chemical processes using only free and open source software. The large problem of stochastic dynamic simulation has been broken down into stages: 1. Input modelling using Markov chain models trained on process data or seeded by hand in addition to stationary distribution models. This enables dynamic scenarios to be handled with the minimum of special case code generation. 2. Process modelling using an object-oriented approach in the Modelica language. Modelica has an actively developed open source implementation called OpenModelica and is an open standard modelling language. 3. Monte Carlo simulation using extensions to the OpenModelica compiler that ease parallel simulations 4. Postprocessing, including visualisation and statistical analysis. Statistics that are generated can be used for control evaluation purposes. The Tennessee-Eastman challenge process is used to illustrate its capabilities.","2011","2025-04-25 16:49:13","2025-04-25 16:49:13","","146-150","","","29","","","","Computer-Aided Chemical Engineering","","","","ELSEVIER SCIENCE BV","SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS","English","","","","","","","ISSN: 1570-7946 Type: Proceedings Paper","","","","Open Source; Segmentation; stochastic modelling","","Pistikopoulos, EN; Georgiadis, MC; Kokossis, AC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is debatable whether they should be used in open-source software (OSS) initiatives. There are studies examining the SRGMs' applicability in the OSS setting, but their scope is constrained by the models and projects they take into account, which could result in inconsistent findings. In this paper, the available SRGMs in the backdrop of OSS have been scrutinized and limitations have been identified. To address these limitations, a modification to the SRGMs using fuzzy neural networks (FNNs) has been proposed. In this paper, various SRGMs have been reviewed and sharp distinction among the same has been made, taking their respective failure intensity and mean value function under consideration. Through the failure intensity of software, it becomes a cakewalk to identify and predict the faults even before they actually arise and necessary and timely action may be initiated. After duly considering the review and contrast between the factors, a FNN model has been suggested for determination of software reliability differing with values of failure intensity and mean value function. First software failure data from a number of open-source software (OSS) projects have been gathered as part of the methodology used to modify traditional SRGMs. The proposed model gives out a high reliability rate and a low failure intensity. The most important factor is that it caters for the faults that are current and are being faced by the users on day to basis currently. It was found that the proposed model has a high success rate with the value of 82.6950937% which is considered as a successful result for software. The suggested FNN model may have a potential impact on the field of software reliability since FNN can handle the ambiguity and imprecision in the software failure data that are typical in open-source projects.","2023-07-04","2025-04-25 16:49:13","2025-04-25 16:49:13","","","","","","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article; Early Access","","","","Software reliability; Software reliability growth model; Failure intensity function; Fuzzy neural network (FNN); Logistic growth; Mean value function","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These volunteers, commonly referred to as OSS project community, serve as the foundation of the OSS project, fostering its creation and sustenance and providing long-term support. The quality and sustainability of the OSS project is reliant upon the development and structure of the self-governing community. When a business organization plans to acquire an OSS solution, it not only takes into consideration the factors such as reliability, security, and scalability but also attaches significant importance to the likelihood of the OSS project being maintained and supported in the future so that it can rely on it as a stable and secure technology solution. Modern cloud-based software hosting platforms, such as GitHub, offer a range of options for automatically and freely accessing the complete development history of millions of OSS projects. This easy availability of detailed development history has enabled researchers to analyze and draw quantitative and scientific inferences about the quality of an OSS project which generally involves assessing three aspects, namely, software product, development process, and project community. With focus on project community part, a Framework for Assessment and Ranking of OSS Community is being presented in the current research work, following a detailed examination of the largest source code hosting and project collaboration platform, GitHub. Technique for Order of Preference by Similarity to Ideal Solution from Multi-Criteria Decision-Making toolkit has been utilized for assessing the quality of the project community. The framework has been validated by applying it on nine OSS projects and comparing the results with the outcomes obtained through an existing OSS evaluation methodology. The comparative analysis demonstrated that the proposed framework aligns with the aforementioned evaluation methodology while offering an opportunity for in-depth analysis on the dynamics of volunteer communities, which is lacking in previous evaluation methods. These insights can prove valuable for both potential adopters and project maintainers, aiding them in making informed strategic decisions. Framework for Project Community Assessment and Ranking follows a phased approach where first phase involves OSS project identification, second phase defines assessment criteria, in third phase data is fetched, stored and metrics are computed; and the last phase involves final Quality Assessment and Ranking. The framework will aid both corporate entities and individual practitioners in identifying an open source project with a robust volunteer community capable of producing a product of exceptional quality.image","2024-07","2025-04-25 16:49:13","2025-04-25 16:49:13","","","","7","36","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","open source software; software quality; multi-criteria decision-making; project community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An increasing rate of urban growth and urban sprawl could induce changes in land use as well as land transformation. However, accurate and up-to-date information about LULC is required for providing better understanding and assessing the environmental consequences of such changes. In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80% and 80.40% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification. To summarize, ArcGIS and QGIS software are reliable to be used in the land cover classification.","2020","2025-04-25 16:49:13","2025-04-25 16:49:13","","","","","540","","","","IOP Conference Series-Earth and Environmental Science","","","","IOP PUBLISHING LTD","DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND","English","","","","","","","Backup Publisher: Inst Geospatial & Remote Sensing Malaysia; Univ Putra Malaysia; Sc & Technol Res Inst Def; Univ Teknologi Malaysia; Univ Utara Malaysia; Int Islam Univ Malaysia; Forest Res Inst Malaysia; GIS Innovat Sdn Bhd; GPS Lands M Sdn Bhd; IEEE Geoscience & Remote Sensing Soc, Malaysia Chapter ISSN: 1755-1307 Type: Proceedings Paper","","","","","","Omar, H; Shariff, ARM; Sathyamoorthy, D; Mat, RC; Tarmidi, Z; Ismail, MH","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.","2021-12-02","2025-04-25 16:49:13","2025-04-25 16:49:13","","","","12","23","","","","","","","","","","English","","","","","","","Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC Type: Article","","","","sustainability; open-source software; cancer informatics; financial model; licensing model; product management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Urban environments must therefore be at the heart of any global energy transition. Furthermore, land availability is a limiting factor for renewable deployment and rooftop PV thus offers a clear advantage. This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 % of the total electricity consumption of the city and where 50 % of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies. Additionally, this article provides valuable information, such as rooftop usability factors, and an overall reduction factor (CT), useful to extend RPVP assessment to larger areas using constant value methods.","2025-03-15","2025-04-25 16:49:13","2025-04-25 16:49:13","","","","","331","","","","","","","","","","English","","","","","","","Place: PO BOX 564, 1001 LAUSANNE, SWITZERLAND Publisher: ELSEVIER SCIENCE SA Type: Article","","","","Open-source software; Energy return on investment (EROI); Geographic information systems (GIS); Net energy analysis (NEA); Photovoltaic potential; Rooftop photovoltaics (RPV)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On this rationale, this study was carried out to explore the applicability of the concept of converging `Free and Open Source Software (FOSS)' to promote sustainable knowledge sharing amongst the agricultural communities in Sri Lanka. A multi-stage community consultative process with a set of designated officials (”Sponsors”) and a series of semi-structured questionnaire survey with a cross section of smallholder agriculture farmers (n=246), were carried out in the Batticaloa, Kurunegala and Puttalam districts to gather the baseline data. This was followed by a number of field experiments (”Campaigns”) with the farmers (n=340) from same geographical areas. The two FOSS, namely: (1) “FrontlineSMS” for `Text Messaging' and (2) “FreedomFone” for `Interactive Voice Responses', were applied to evaluate the effectiveness of knowledge sharing within the farming communities. It was found that FOSS intervention increases the `Text messaging' and `Voice Call' usage in day-to-day agricultural communication by 26 and 8 percent, respectively. The demographic factors like age and educational level of the farmers have a positive influence on the knowledge sharing process. And also the `Mobile Telephony' was the most extensive mode of communication within the communities. The outcome of analysis, as a whole, implies that, with a fitting mechanism in place, this approach can be promoted as a “drive for positive changes” in agriculture-based rural communities in developing countries like Sri Lanka, and those in South and East Asia with similar socioeconomic and cultural perspectives.","2017","2025-04-25 16:49:13","2025-04-25 16:49:13","","351-359","","2","111","","","","","","","","","","English","","","","","","","Place: VIA ANTONIO COCCHI 4, FLORENCE, 50131, ITALY Publisher: AGENZIA ITALIANA COOPERAZIONE SVILUPPO-ITALIAN DEV COOP AGENCY Type: Article","","","","FOSS; Information; Knowledge sharing; Agricultural community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

SU2 is one of these open -source tools. Unlike other open -source alternatives, SU2 is equipped with boundary condition types, solvers and methods that are especially developed for the analysis and design of turbomachinery. The aim of this work is to explore and investigate the capabilities of SU2 in the prediction of performance parameters of radial compressors. Two different single stage shrouded compressor geometries, one with a vaneless diffuser and the other with a vaned diffuser have been investigated with steady state CFD. The compressors were designed by MAN Energy Solutions Schweiz AG. Computational results with SU2 showed a satisfactory agreement with both the experimental data and reference CFD solutions obtained with Fidelity Flow, which is formerly known as Numeca Fine TURBO. Only at the relatively higher mass flow rates the difference between references and SU2 were higher compared to other operating points. After performance parameters were successfully calculated with SU2, the optimization tools that come with SU2 were also used. A 2D adjoint optimization study on the vane of the vaned diffuser was carried out. The study was carried out at a single operating point that is close to choke conditions. The loss generated by the large separated flow region at the suction side of the diffuser vane was reduced by 0.55 % in the optimized geometry using minimal modifications on the existing vane geometry to keep the performance of the compressor intact at other operating points. However, the resulting modification increased the total pressure loss by 0.86 % at one of the design operating points. This performance penalty could be due to the discontinuity in the vane geometry generated by the optimizer. Overall, the study shows that SU2 has the basic numerical schemes and models that are required for the analysis of radial turbomachinery flows and geometry optimization.","2023","2025-04-25 16:49:13","2025-04-25 16:49:13","","233-242","","2","43","","","","","","","","","","English","","","","","","","Place: TIBTD MAKINA MUHENDISLIGI BOLUMU ODTU, ANKARA, 06531, Turkiye Publisher: TURKISH SOC THERMAL SCIENCES TECHNOLOGY Type: Article","","","","Optimization; Open-source; Compressor; Computational Fluid Dynamics; SU2; Turbomachinery","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio [finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing.

To further investigate this specific barrier, we conducted a qualitative analysis with data obtained from semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members. We used procedures of Grounded Theory-open and axial coding-to analyze the data. We found that newcomers are not confident enough to choose their initial task and they need information about the tasks or direction from the community to support choosing a task more suitable for them.

We participated as volunteers in this project, although we did not have the authorization of the leading developer. To validate the effectiveness of the adapted technique, tests were conducted with representative users, covering a variety of interactions with the Koodo Reader interface. The results of these tests were used for prototyping, which was evaluated and validated by the user community of the Koodo Reader project. In conclusion, the successful application of the Interface Content Modeling technique has proven to be a tool that helps improve the quality of projects.

In these studies, segmentation and quantification of myocardial infarct lesion are often performed with a commercial software or an in-house closed-source code development thus creating a barrier for reproducible research. This paper introduces CMRSegTools: an open-source application software designed for the segmentation and quantification of myocardial infarct lesion enabling full access to state-of-the-art segmentation methods and parameters, easy integration of new algorithms and standardised results sharing. This post-processing tool has been implemented as a plug-in for the OsiriX/Horos DICOM viewer leveraging its database management functionalities and user interaction features to provide a bespoke tool for the analysis of cardiac MR images on large clinical cohorts. CMRSegTools includes, among others, user-assisted segmentation of the left-ventricle, semi- and automatic lesion segmentation methods, advanced statistical analysis and visualisation based on the American Heart Association 17-segment model. New segmentation methods can be integrated into the plug-in by developing components based on image processing and visualisation libraries such as ITK and VTK in C++ programming language. CMRSegTools allows the creation of training and testing data sets (labeled features such as lesion, microvascular obstruction and remote ROI) for supervised Machine Learning methods, and enables the comparative assessment of lesion segmentation methods via a single and integrated platform. The plug-in has been successfully used by several CMR imaging studies.","2022-09-13","2025-04-25 16:49:14","2025-04-25 16:49:14","","","","9","17","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 16:49:14","2025-04-25 16:49:14","","119-139","","1","39","","","","","","","","","","English","","","","","","","Place: Floor 5, Northspring 21-23 Wellington Street, Leeds, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Open source software; Motivations; Open content; Social Q&A","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In Indonesia alone, 25% of South East Asia's mangroves are at a risk. The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was “Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang” held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes. Field work activity conducted and confirmed the changes that occurred in the study areas. Our study shows that all of the two districts exhibit successfulness of the plantation program.

Drawing on signaling theory, this manuscript explores how third-party assessment can influence a developers' decision to join an OSS project. In order to test it, vignette survey study was conducted manipulating reputation, development experience, and a number of current OSS projects of existing developers in the OSS project. The findings suggest that all three signals have a positive influence on developer's decision to join the OSS project.

In the case of biological sciences, information commons, such as public biobanks and free/libre open source software (FLOSS), are of paramount importance for both research and the bioeconomy. In a time of digitalization, however, information commons are vulnerable to violations, such as the free-rider problem, that render the commons unsustainable. Consequently, it has been argued that the enclosure of the informational common resources is the only means to effectively exploit them. Given the social and economic importance of the information commons, the new digital environment in biology and health requires governance innovation that will regulate the social embedding of the commons and their relationship to the free market, that is, a new political economy is needed. In this context, the need for a core common infrastructure, stretching from the physical to the logical and content layer of the information environment, that will guarantee the protection of the commons from both violations and enclosures, has been highlighted. Focusing on the interaction between two biological/bioinformatics commons, namely public biobanks and the FLOSS, we have set up an ecosystem relying on a blockchain technology. The proposed governance mechanism protects the information commons from the free-rider problem and guarantees their sustainability without hampering their operational framework. Our model demonstrates the interdependence and protection of the information commons not as an abstract theoretical exercise, but rather as a physical reality on the digital ontological matrix.","2020-05-01","2025-04-25 16:49:14","2025-04-25 16:49:14","","278-285","","5","24","","","","","","","","","","English","","","","","","","Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC Type: Article","","","","digitalization; political economy; blockchain; free; libre open source software; public biobanks; the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Key considerations when considering prognostic enrichment include: clinical trial sample size; the number of patients one must screen to enroll the trial; and total patient screening costs and total per-patient trial costs. The Biomarker Prognostic Enrichment Tool for Survival Outcomes (BioPETsurv) is a suite of methods for estimating these elements to evaluate a prognostic enrichment biomarker and/or plan a prognostically enriched clinical trial with a time-to-event primary endpoint. BioPETsurv allows investigators to analyze data on a candidate biomarker and potentially censored survival times. Alternatively, BioPETsurv can simulate data to match a particular clinical setting. BioPETsurv's data simulator enables investigators to explore the potential utility of a prognostic enrichment biomarker for their clinical setting. Results demonstrate that both modestly prognostic and strongly prognostic biomarkers can improve trial metrics such as reducing sample size or trial costs.

Although open source software (OSS) is not a new idea, several product development companies that operate in a market-driven context have started to use open source solutions as core software components in their products. Adopting open source core components implies a lower degree of control over software development and increased business risk associated with integrating differentiating contributions into the core release stream. Whether and how to adjust the current requirements management practices after the adoption of OSS components to fully benefit from the concept of open innovation has not yet been empirically explored. We outline experiences and challenges related to leveraging open innovation via engaging in OSS identified during 19 interviews with practitioners occupying different roles in the requirements management process at a large company followed by four validation interviews with other practitioners. We then propose a research agenda for requirements and decision management in the open innovation context and suggest which challenges in requirements engineering open innovation affects.","2012","2025-04-25 16:49:14","2025-04-25 16:49:14","","271-279","","","","","","","International Symposium on Empirical Software Engineering and Measurement","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery (ACM); ACM Special Interest Grp Software Engn (SIGSOFT); IEEE Comp Soc (CS) ISSN: 1938-6451 Type: Proceedings Paper","","","","open innovation; open source software; Case study; software requirements management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.","2023","2025-04-25 16:49:15","2025-04-25 16:49:15","","180-190","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Elsevier; Digital Govt Soc; Gdansk Univ Technol, Res Univ Excellence Initiat; Fdn Lech Walesa Inst; Marshal Pomorskie Voivodeship; President City Gdansk; Rector Gdansk Univ Technol; Gdansk Univ Technol, Fac Management & Econ Type: Proceedings Paper","","","","GitHub; open source software; government; barriers; benefits; citizen engagement; evidence","","Sabatini, N; Hagen, L; Liao, HC; Cid, DD","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While 3DP has gained tremendous popularity, it remains a daunting and perceptibly time-consuming process for the inexperienced user, with most turning to commercially printed products. Commercial vendors are expensive. We propose that 3DP is feasible for the inexperienced user with the appropriate knowledge and tools.Methods: A 3DP protocol was created for model design and printing using open-source software and a low-cost desktop printer. It was betatested by 3 inexperienced users. The fidelity of the protocol was then tested in direct comparison to industry models made for 3 patients undergoing mandibular distraction osteogenesis, using standard cephalometric measurements.Results: All inexperienced testers were able to successfully create a 3D model using the easy-to-follow protocol without the use of any other resources. The models were created in a mean time of 170 minutes. All cephalometric measurements on the open-source printed models were equal to within 0.5 to 1.0 mm of the respective industry models.Conclusions: As the 3DP process is simplified and desktop printers and materials become more affordable, we anticipate that its implementation will become more commonplace. We describe a step-by-step, protocol using open-source software and affordable materials to create 3D models.","2022-03","2025-04-25 16:49:15","2025-04-25 16:49:15","","66-73","","1","3","","","","","","","","","","English","","","","","","","Place: 2455 ℡LER RD, THOUSAND OAKS, CA 91320 USA Publisher: SAGE PUBLICATIONS INC Type: Article","","","","open source; 3D printing; craniofacial; stereolithography","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage. The empirical investigation in this paper shows that the switching points of stages have meaningful associations with the release dates.","2014","2025-04-25 16:49:15","2025-04-25 16:49:15","","207-212","","","","","","","EUROMICRO Conference Proceedings","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISSN: 1089-6503 Type: Proceedings Paper","","","","","","Rabiser, R; Torkar, R","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nowadays, it is becoming challenging to procure bone legally, resulting in medical students' inadequacy of bone. Plaster -of -Paris or resin bone models sold on the market are less detailed than real bones. Aims and objectives This study aims to create a three-dimensional (3D)-printed human bone model with free, open-source software and fused deposition modelling (FDM) 3D printers, compare its accuracy with the original bones and validate it with a textbook description. Methods Scapula and hip bone models were produced using open-source software 3D Slicer from computed tomography (CT) data from the “New Mexico Decedent Image Database”. After automated segmentation, bones were edited manually with tools in a 3D Slicer (https://www.slicer.org/) and Meshmixer software (Autodesk Inc., San Rafael, California, United States) and 3D bone models were printed using polylactic (PLA) filament. Results and discussions 3D digital models of both bones were successfully created with the maximum possible accuracy with an FDM 3D printer. A 3D digital replica of the scapula obtained after segmentation retained most anatomical features except for the glenoid cavity, as the head of the humerus obscured the glenoid cavity. The 3D digital skeleton of the hip bone retained all anatomical features except articulating surfaces, such as the acetabulum and auricular surface ilium, which were obscured by the head of the femur and sacrum. A few morphological features of both bones differed from the original dry bone, and a few finer details were unclear in the iliac fossa and ischium. After manual editing and post -processing, the final physical model obtained has all the features. Conclusions We conclude that it is possible to produce anatomically accurate models with the greatest possible resemblance and accuracy to the original bones using free and open-source data with an FDM 3D printer.","2024-05-13","2025-04-25 16:49:15","2025-04-25 16:49:15","","","","5","16","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON, N1 9XW, ENGLAND Publisher: SPRINGERNATURE Type: Article","","","","3d printing; 3d slicer; image segmentation; innominate; scapula","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Almost every company nowadays has a website, particularly those that cater to digital or internet-based clientele. Starting a modest online store is straightforward, but as the company expands, the expectations get more specialized, and they are not met. Unfortunately, “ready to go” solutions are typically resistive to acceptance, meaning that all individual changes are not warmly welcomed. This study analyzed and compared the two types of software used in building e-commerce websites in the Philippines' popular websites and detected the current web technologies and conducted an online survey using qualitative approach with the participation of experts and familiar with e-commerce system. It also to identified what are the things need to consider when choosing software.

This paper seeks to broaden the research on virtual communities by applying the theory of competency rallying (TCR) in a longitudinal manner to examine the impact of task identification, task assignment, task execution and task management on user interest in open source software (OSS) projects defined by popularity and communication. The aim of this paper is: (I) re-conceptualizing the concept of user interest and broadening our understanding of user interest by incorporating users' post-usage behaviors, (2) examining the effect of various tasks involved in an OSS project's key processes of defect-fixing and feature-enhancement on user interest. The current study found that project popularity is positively influenced by task assignment, task execution and task management. Additionally, user communication was found to be positively impacted by task identification and task execution. The data collected from 1178 OSS projects in a longitudinal manner (at 3 time points over a period of 16 months) confirmed the expectations from TCR and also demonstrated that over time the effects that development of competencies and managing short term cooperative work have on project success might increase, while the impact of identifying market needs and marshalling competencies may not significantly change.

In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere. I argue that these competing views are consequential, for they link technical artifacts and political agents in practice, by way of aspirations, obligations, and forms of authority. Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.","2007-05","2025-04-25 16:49:15","2025-04-25 16:49:15","","211-235","","2","93","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","free and open source software; artifact; Bruno Latour; public sphere theory; socio-technical deliberation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work introduces Dareplane, a modular and broad technology-agnostic open source software platform for brain-computer interface (BCI) research with an application focus on adaptive deep brain stimulation (aDBS). One difficulty for investigating control approaches for aDBS resides with the complex setups required for aDBS experiments, a challenge Dareplane tries to address. Approach. The key features of the platform are presented and the composition of modules into a full experimental setup is discussed in the context of a Python-based orchestration module. The performance of a typical experimental setup on Dareplane for aDBS is evaluated in three benchtop experiments, covering (a) an easy-to-replicate setup using an Arduino microcontroller, (b) a setup with hardware of an implantable pulse generator, and (c) a setup using an established and CE certified external neurostimulator. The full technical feasibility of the platform in the aDBS context is demonstrated in a first closed-loop session with externalized leads on a patient with Parkinson's disease receiving DBS treatment and further in a non-invasive BCI speller application using code-modulated visual evoked potential (c-VEP). Main results. The platform is implemented and open-source accessible on https://github.com/bsdlab/Dareplane. Benchtop results show that performance of the platform is sufficient for current aDBS latencies, and the platform could successfully be used in the aDBS experiment. The timing-critical c-VEP speller could be successfully implemented on the platform achieving expected information transfer rates. Significance. The Dareplane platform supports aDBS setups, and more generally the research on neurotechnological systems such as BCIs. It provides a modular, technology-agnostic, and easy-to-implement software platform to make experimental setups more resilient and replicable.","2025-04-01","2025-04-25 16:49:15","2025-04-25 16:49:15","","","","2","22","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP Publishing Ltd Type: Article","","","","open source software; brain-computer interface; brain-machine interface; c-VEP; closed-loop; deep brain stimulation; electrophysiology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then, it has become practically essential for identifying bacteria in microbiological diagnostic laboratories. In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from. MSProfileR has been developed in the R environment and offers a user-friendly web interface using the R Shiny framework. It is available on Microsoft Windows as a web browser application by simple navigation using the link of the package on Github v.3.10.0. MSProfileR is therefore accessible to non-computer specialists and is freely available to the scientific community. We evaluated MSProfileR using two datasets including exclusively MS spectra from arthropods. In addition to coherent sample classification, outlier MS spectra were detected in each dataset confirming the value of MSProfileR.","2024-06","2025-04-25 16:49:15","2025-04-25 16:49:15","","","","2","11","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","Github; R package; arthropod vectors; MALDI-TOF MS; quality control; rstudio; Shiny interface","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In that community, companies always play auxiliary roles, and integrate the result of OSS into their business activities. However, in the Eclipse open source software community, the main role of OSS development activities is taken over by companies. The relationship between individuals and companies is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of a company. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify a structure of co-creation in an OSS ecosystem led by companies considering the Eclipse community as one particular case. It also constructs a co-creation process model to promote sustainable development for an OSS ecosystem following two axes 1) value sharing and value acquisition, and 2) quantitative development and qualitative development. Some mechanisms that drive this process are embedded everywhere in the Eclipse ecosystem.","2011","2025-04-25 16:49:15","2025-04-25 16:49:15","","","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: Portland State Univ, Maseeh Coll Engn & Comp Sci, Dept Engn & Technol Management; Portland State Univ, Off Informat Technol; IKON Off Solut Type: Proceedings Paper","","","","","","Kocaoglu, DF; Anderson, TR; Daim, TU","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated. Based on our findings, we offer suggestions for projects to incorporate and manage episodic volunteers, so as to better leverage this type of contributors and potentially improve projects' sustainability.","2019","2025-04-25 16:49:15","2025-04-25 16:49:15","","948-959","","","","","","","International Conference on Software Engineering","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE Comp Soc, Tech Comm Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","open source software; community management; episodic volunteering; volunteer management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although multitude of studies have provided effective models for OSS sustainability, their practical implications have been lacking because most identified features are not amenable to direct tuning by developers (e.g., levels of communication, number of commits per project). In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed a comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs). The ReACTs are practical advice with specific steps, found in prior work to associate with tangible results. Starting from a set of sustainability-related features, this study contributes 105 ReACTs to the SE community by analyzing 186 published articles. Moreover, this study introduces a newly developed tool (ReACTive) designed to enhance the exploration of ReACTs through visualization across various facets of the OSS ecosystem. The ReACTs idea opens new avenues for connecting SE metrics to actionable research in SE in general.","2024","2025-04-25 16:49:16","2025-04-25 16:49:16","","457-461","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSOFT; Huawei; Technol Innovat Inst; Google; JetBrains; Uber Type: Proceedings Paper","","","","Open Source Software; Sustainability; Literature Review; Research Actionable","","D'Amorim, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

FLOSS communities and products have been studied as complementary to proprietary software companies and products. In this paper we propone a business model for the software market, and in particular we analyze the competition between proprietary software firms and FLOSS firms. Our software market is a system where each agent is independent of each other in the choice about buying or selling software products or services. The proposed work aims to analyze the influence of FLOSS firms producing both software and services in vertical software markets, nowadays mostly dominated by large proprietary firms. The findings show that FLOSS firms are able to compete with proprietary firms, though in the end a monopoly or oligopoly of the latters emerges. The ousted FLOSS firms, however, survive longer than proprietary ones, when these are not able to compete in the market.","2011","2025-04-25 16:49:16","2025-04-25 16:49:16","","56-69","","","80","","","","Lecture Notes in Business Information Processing","","","","SPRINGER-VERLAG BERLIN","HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY","English","","","","","","","ISSN: 1865-1348 Type: Proceedings Paper","","","","business model; Free/Libre Open Source Software; market strategy; simulation model","","Regnell, B; VanDeWeerd, I; DeTroyer, O","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As the ability of the variometric approach to detect short-term dynamic behaviors in real-time mode in applications such as Global Navigation Satellite Systems (GNSS)-seismology and structural health monitoring is demonstrated, the demand for open-source VA software is increasing. However, open-source software that is capable of VA processing in real-time mode based on single- and dual-frequency multi-GNSS observations is scarce. In view of this fact, we have developed an open-source VA processing software called PPPH-VA that can evaluate single- and dual-frequency multi-GNSS observations in real-time mode. PPPH-VA is developed in the MATLAB environment, and it can simultaneously process GPS, GLONASS, Galileo, BeiDou-2, and BeiDou-3 data with the VA technique in real-time mode, employing both single- and dual-frequency observations. We evaluated PPPH-VA using shake table experiments based on real data, and the results demonstrate that it provides high accuracy in terms of detection of dynamic displacements. Toolbox can successfully detect the dominant frequencies of short-term dynamic behaviors and is capable of determining the amplitude values corresponding to the peak frequency at the sub-mm level. Moreover, in the time domain, it can obtain dynamic behaviors with an accuracy of millimeters.","2024-01","2025-04-25 16:49:16","2025-04-25 16:49:16","","","","1","28","","","","","","","","","","English","","","","","","","Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG Type: Article","","","","Open-source software; Dynamic displacement; High-rate; Multi-GNSS; PPPH-VA; Real-time; Variometric approach","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most large and complex software packages partitioned across multiple portals and involve many users - each with their role in the software package; those users have different perspectives on the software package, defined by their knowledge, responsibilities, and commitments. Thus, a multi-perspective approach has been used in usability evaluation to overcome the challenge of inconsistency between users' perspectives; the inconsistency challenge would lead to an ill-advised decision on the selection of a suitable OSS. This study aimed to assist the public and private organizations in evaluating and selecting the most suitable OSS. The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.","2023-01","2025-04-25 16:49:16","2025-04-25 16:49:16","","187-277","","01","22","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","evaluation; selection; open-source software (OSS); benchmarking; BWM; decision matrix; Multi-criteria decision making (MCDM); VIKOR","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project's capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of subtopics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project's overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.","2022","2025-04-25 16:49:16","2025-04-25 16:49:16","","","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Univ Rey Juan Carlos; Vicerrectorado Extens Univ; GsyC/LibreSoft Res Grp; Programamos.es; John Ernest Fdn; ACM In Cooperat; SIGSOFT; SIGWEB Type: Proceedings Paper","","","","Health; Open Source Software; Sustainability; Software Quality; Software Ecosystem","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then countless libraries across the United States have used the program to create online tutorials in order to teach a variety of information literacy skills including how to search databases, how to evaluate websites, how to create better searches, and how to search for medical information. The Guide on the Side was created by a group of University of Arizona librarians in order to replicate the hands-on experience students received when they attended a library session on how to use a research database. Librarians aimed to give students the guided instruction they received in face-to-face sessions. Sophisticated research databases are often difficult for undergraduate students to use, and they need both background knowledge and repeated practice to use a database successfully. With the Guide on the Side, students are presented with authentic tasks and are able to conduct “live” searches as they are guided through the database. Through these activities, they learn how to locate the information they need quickly. Although a valuable and easy to use software program, instructors and librarians are often at a loss for how to create tutorials that are appealing to students and that are aligned with best practices for online instruction. This paper will focus on best practices when using the Guide on the Side. These best practices have been developed by the author and are based on current educational research focused on online instruction and on usability studies conducted using the Guide on the Side. This paper discusses the development of the Guide on the Side, how to download it, and how to implement these best practices in order to create learning experiences for students that are both engaging and effective.","2017","2025-04-25 16:49:16","2025-04-25 16:49:16","","395-400","","","","","","","INTED Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1079 Type: Proceedings Paper","","","","information literacy; guide on the side; library; online instruction; tutorials","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we here propose an information system that facilitates the use of BIM for geo-analysis purposes. BIM4GeoA is a concept for combining existing open source software and open specification for efficient data management and analysis of Building Information within its boarder context. The core components are the spatial database PostgreSQL/PostGIS, the building information server, the industrial foundation class (IFC), the Google Earth 3D viewer, and the existing 3D OGC standard (KML, CityGML). This paper presents the procedure used to enable the development of this new expert system as applied to the context of 3D Web GIS. A thorough analysis of the strength and weakness of these different components has been undertaken to employ it is strength and override its weakness. The system architecture is operationally used in developing different applications for the management of a university campus; a large potential is provided for operational tasks of facility management department, such as utilities infrastructure, as well as public community (student, staff) like routing application, searching for a person with defined criteria.","2010","2025-04-25 16:49:16","2025-04-25 16:49:16","","45-49","","","38-4","","","","International Archives of the Photogrammetry Remote Sensing and Spatial Information Sciences","","","","COPERNICUS GESELLSCHAFT MBH","BAHNHOFSALLE 1E, GOTTINGEN, 37081, GERMANY","English","","","","","","","Backup Publisher: Int Soc Photogrammetry & Remote Sensing ISSN: 2194-9034 Issue: W15 Type: Proceedings Paper","","","","Open Source; Information system; 3D GIS; BIM; CAD; Open Specification","","Kolbe, TH; Konig, G; Nagel, C","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This rise to prominence can be attributed to the high quality and suitability of the software. This quality and suitability is achieved through an elaborate peer-review process performed by a large community of users, who act as co-developers to identify and correct software defects and add features. Although this process is crucial to the success of free software projects, there is more to the free software development than the creation of a `bazaar'. In this paper we draw on existing free software projects to define a lifecycle model for free software. This paper then explores each phase of the lifecycle model and agrees that, while the bazaar phase attracts the most attention, it is the initial modular design that accommodates diverse interventions. Moreover, it is the period of transition from the initial group to the larger community based development that is crucial in determining whether a free software project will succeed or fail.","2004","2025-04-25 16:49:17","2025-04-25 16:49:17","","84-91","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: Korea Informat Sci Soc; Korea Soc Engn Fdn; Samsung Elect; Samsung SDS; LG Elect; Korea IT Ind Promto Agcy; Elect & Telecommun Res Inst Type: Proceedings Paper","","","","free software; development process; software lifecycle","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. “simple”, intermediate” or “complex”, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.","2020-07-15","2025-04-25 16:49:17","2025-04-25 16:49:17","","","","","266","","","","","","","","","","English","","","","","","","Place: 24-28 OVAL RD, LONDON NW1 7DX, ENGLAND Publisher: ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD Type: Article","","","","Remote sensing; Cover estimation; Ecological monitoring; Guidos toolbox; Invasive alien species; Morphological spatial pattern analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.","2001-10","2025-04-25 16:49:17","2025-04-25 16:49:17","","277-304","","4","11","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","trust; control; McDonaldization; networked organization; rationalization; virtual organization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess “proof” of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and activities match those in their paid employment. Following a cohort of OSS programmers over a six-year period, we empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, our findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18% increase in wages. Moreover, we find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management. These findings suggest that rank within an OSS meritocracy is a credible and precise signal of participants' productive capacity and that participants' roles and activities in an OSS community have additional financial value when aligned with their paid employment.","2013-09","2025-04-25 16:49:17","2025-04-25 16:49:17","","520-538","","3","24","","","","","","","","","","English","","","","","","","Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS Type: Article","","","","open source software; signaling theory; job matching theory; labor economics; software industry","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On one hand, most FOSS systems are based on very fine-grained units of software deployment - called packages - which promote system evolution; on the other hand, FOSS systems are among the largest software systems known and require sophisticated static and dynamic conditions to be verified, in order to successfully deploy upgrades on users' machines. The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V.

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.","2013-12","2025-04-25 16:49:17","2025-04-25 16:49:17","","361-370","","4","38","","","","","","","","","","English","","","","","","","Place: TWO COMMERCE SQ, 2001 MARKET ST, PHILADELPHIA, PA 19103 USA Publisher: LIPPINCOTT WILLIAMS & WILKINS Type: Article","","","","open source software; qualitative research; health information technology; hospital administration; vendors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.","2009-07-17","2025-04-25 16:49:17","2025-04-25 16:49:17","","","","","8","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, cognitively translating 2D images to surgical settings can be difficult and lead to sub-optimal resections. Lymph node dissection can be challenging due to the inability to locate small metastatic lesions, and their proximity to at-risk organ(s). 3D volume rendered (3D-VR) patient specific images can help to address these challenges. We created patient-specific 3D-VR images using freely available open-source programs. Methods: This study included patients part of the clinical trial NCT04857502. Patients received a PET/CT prior to radioguided surgery. 3D Slicer was used to segment anatomy of interest (organs and tumor lesion(s)). After segmentation, the data was exported as an .OBJ file with an accompanying .MTL file. Manipulation of the .MTL file to restore model properties to the .OBJ file, were completed and both files were uploaded into Autodesk Viewer. Surgeons then received an email link to access the finished 3D-VR model on their smartphone or laptop for peri-operative preparation and/or guidance. Results: The method was used in a series of 14 patients with prostate cancer undergoing pelvic lymph node dissection with PSMA-radioguided robotic surgery using pre-operative PSMA PET/CT images acquired on average 103 +/- 69 days prior to resection. The creation of the 3D-VR models was successfully conducted in all 14 cases. In all cases, the lesions identified on the pre-operative PET/CT imaging 3D-VR models were successfully removed during surgery. Conclusion: We created patient-specific anatomical 3D-VR models that the surgeons can use for pre-surgical planning and intraoperative tumor localization, by applying free, open-source software that could be used in any procedure requiring careful and strategical planning.","2025-04","2025-04-25 16:49:17","2025-04-25 16:49:17","","10-16","","","236","","","","","","","","","","English","","","","","","","Place: 525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA Publisher: ACADEMIC PRESS INC ELSEVIER SCIENCE Type: Article","","","","3D imaging; 3D volume rendered models; Anatomical models; Pelvic lymph node dissection; PET/CT; PSMA; Radioguided surgery; Surgical planning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We identify a novel refinement and resolution process that all studied requirements followed from their inception to complete realization and subsequent release. Noticing some interesting phenomena more specific to non-functional requirements (NFRs), we conduct a second study examining 50 NFRs from the aforementioned three subject systems. This study reveals a slightly different process followed in the refinement and resolution of NFRs. It also provides further evidence that NFR refinement and resolution activities focus more on implementation refinement rather than requirement elaboration in the studied systems. Our research provides new insights into how OSS project teams create quality features from simple initial descriptions of JIT requirements, uncovers activities more particular to JIT requirements engineering (RE) for NFRs, and opens new avenues for further research in the emerging JIT RE field.","2019-06","2025-04-25 16:49:17","2025-04-25 16:49:17","","24-33","","","14","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","Functional requirements; Just-in-time requirements; Non-functional requirements; Refinement; Resolution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-25 16:49:17","2025-04-25 16:49:17","","2366-2380","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSAC; Huawei; Natl Sci Fdn; Technol Innovat Inst; Twenty Second Century Dora Technol; Ant Res; IBM; TikTok; Abelian; Input Outut Type: Proceedings Paper","","","","Patch backporting; Patch Semantics; Patch type","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On the other hand, an effective method of quality management has not been established due to the unique development characteristics such as no testing phase. In this paper, we assume that the number of fault-detections observed on the bug tracking system tends to infinity, and discuss a method of statistical process control (SPC) for OSS projects by applying the logarithmic Poisson execution time model as a software reliability growth model (SRGM) based on a nonhomogeneous Poisson process (NHPP). Then, we propose a control chart method based on the logarithmic Poisson execution time model for judging the statical stability state, and estimating the additional development time for attaining the objective software failure intensity, i.e., the target value of the instantaneous fault-detection rate per unit time. We also discuss an optimal software release problem for determining the optimum time when to stop OSS development and to transfer it to user operation. Further, numerical illustrations for SPC are shown by applying the actual fault-count data observed on the bug tracking system.","2016-10","2025-04-25 16:49:17","2025-04-25 16:49:17","","","","5","23","","","","","","","","","","English","","","","","","","Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD Type: Article","","","","Open source software (OSS); additional development time; control chart; logarithmic Poisson execution time model; software reliability growth model (SRGM); statistical process control (SPC)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We have developed a new generic software package for the solution of inverse problems implementing the Ensemble Smoother with Multiple Data Assimilation (genES-MDA). It is an open-source, platform-independent Python-based program. Its aim is to facilitate the management and configuration of the ES-MDA through several programming tools that help in the preparation of the different steps of ES-MDA. genES-MDA has a flexible workflow that can be easily adapted for the implementation of different variants of the ensemble Kalman filter and for the solution of generic inverse problems. This paper presents a description of the package and some application examples. genES-MDA has been tested in three synthetic case studies: the solution of the reverse flow routing for the estimation of the inflow hydrograph to a river reach using observed water levels and a calibrated forward model of the river system, the identification of a hydraulic conductivity field using piezometric observations and a known forward flow model, and the estimation of the release history of a contaminant spill in an aquifer from measured concentration data and a known flow and transport model. The results of all these tests have demonstrated the flexibility of genES-MDA and its capabilities to efficiently solve different types of inverse problems.","2022-10","2025-04-25 16:49:17","2025-04-25 16:49:17","","","","","167","","","","","","","","","","English","","","","","","","Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND Publisher: PERGAMON-ELSEVIER SCIENCE LTD Type: Article","","","","Python; Covariance localization and inflation; Stochastic inverse modeling; Uncertainty characterization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this work we focus our attention on what is perceived of a source code when investigating its structure. We do this considering that structure as a proxy for the conceptual architecture of the application. A metric is developed based on some current assumptions, and it is tested over a sample of Open Source projects. What is interesting to note, is that refactoring efforts are clearly visible when intended as reduction of complexity of source code. Our second observation is that, based on what an Open Source software currently does, i.e. its application domain, there's a threshold value that several projects tend to.","2004","2025-04-25 16:49:18","2025-04-25 16:49:18","","58-66","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE Comp Soc, TCSE; Nokia; TietoEnator; Tampere Univ Tech ol; Acad Finland; Reengineering Forum Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Model predictive control (MPC) has been shown to be a successful control strategy generally and as well as for managing urban drainage specifically. This research describes and demonstrates the implementation of MPC for urban drainage systems using open source software (Python and The United States Environmental Protection Agency (EPA) Storm Water Management Model (SWMM5). The system was demonstrated using a simplified use case in which an actively-controlled outlet of a detention pond is simulated. The control of the pond's outlet influences the flood risk of a downstream node. For each step in the SWMM5 model, a series of policies for controlling the outlet are evaluated. The best policy is then selected using an evolutionary algorithm. The policies are evaluated against an objective function that penalizes primarily flooding and secondarily deviation of the detention pond level from a target level. Freely available Python libraries provide the key functionality for the MPC workflow: step-by-step running of the SWMM5 simulation, evolutionary algorithm implementation, and leveraging parallel computing. For perspective, the MPC results were compared to results from a rule-based approach and a scenario with no active control. The MPC approach produced a control policy that largely eliminated flooding (unlike the scenario with no active control) and maintained the detention pond's water level closer to a target level (unlike the rule-based approach).","2019","2025-04-25 16:49:18","2025-04-25 16:49:18","","988-992","","","","","","","Green Energy and Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","ISSN: 1865-3529 Type: Proceedings Paper","","","","Active stormwater control; Flood prevention; Low-relief coastal cities; Model predictive control","","Mannina, G","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.","2016","2025-04-25 16:49:18","2025-04-25 16:49:18","","37-44","","","","","","","Proceedings of the European Conference on Knowledge Management","","","","ACAD CONFERENCES LTD","CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND","English","","","","","","","ISSN: 2048-8963 Type: Proceedings Paper","","","","knowledge sharing; communities of practice; clusters; free software communities; sharing profiles","","Moffett, S; Galbraith, B","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

India is the largest consumer of water, with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11-01","2025-04-25 16:49:18","2025-04-25 16:49:18","","597-625","","4","42","","","","","","","","","","English","","","","","","","Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD Type: Article","","","","open source; free software; reputational capital; copyleft; immaterial labour; new spirit of capitalism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computed tomography (CT) is commonly used to overcome projection errors in two-dimensional angular measurements of dog hindlimb alignment. Three-dimensional volume rendering (VR) techniques permit virtual positioning and variable projection, but the final CT-image that defines the projection plane for angular measurements remains two-dimensional.Objective We wanted to develop a true three-dimensional open-source technique to measure the alignments of the hind limbs of dogs in CT scanners.Methods We developed an open-source 3D Slicer plug-in, to perform angular measurements using vector calculations in three-dimensional space. In 113 CT-scans of canine pelvic limbs, femoral torsion, femoral varus, femorotibial rotation, tibial torsion, tibial varus and tibiotalar rotation angles were calculated and compared to an already validated technique using VoXim (R).Results Reference points were identified and measurements were possible in the 113 acquisitions. The greatest difference between the two techniques was 1.4 degrees at only one tibial torsion angle. Mean values for all Bland-Altman plots did not show significant differences and were less than 0.07 degrees for all comparisons.Discussion Based on these results we considered angular measurements of canine hind limb alignment in CT scans using the 3D Slicer extension program sufficiently accurate for clinical orthopedic and surgical purposes in veterinary medicine.Conclusion With our open-source 3D Slicer extension software, we provide a free accessible tool for veterinary orthopedic surgeons and thus we hope to improve angular measurements in CT-scans of canine hind limb deformities through true three-dimensionality.","2024-03-29","2025-04-25 16:49:18","2025-04-25 16:49:18","","","","3","19","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community.

Materials and Methods: Ten STL dental and maxillofacial models were obtained from various imaging technologies, including intraoral scanners, computer-aided design (CAD) software, and cone-beam computed tomography (CBCT), and saved as STL files. ChatGPT was used to generate Python scripts in Blender for mesh simplification and data compression, which were then saved as .py files. The models were regenerated from these scripts in Blender, and their accuracy was assessed using GOM Inspect software, comparing trueness and precision. Statistical analysis, including Kruskal-Wallis and Mann-Whitney tests, was conducted to evaluate differences in file sizes between the original, Python-generated, and regenerated STL files, with statistical analyses performed at a level of significance alpha=0.05. Results: The scripting-based technique was successfully utilized in ChatGPT to generate Python script code for accessing comprehensive data on STL models, utilizing Blender's scripting functionality. This approach enabled the generation, regeneration, and visualization of STL models, resulting in significantly smaller file sizes for both the Python script and regenerated STL files compared to the original STL files (p < 0.001). No significant differences in trueness were observed, with deviations ranging from 0.0 m to 6.8 mu m, and all regenerated STL models demonstrated perfect precision. Additionally, a proportional relationship was noted between the original STL file sizes and processing times. Conclusions: The scripting-based approach proved to be effective in coding, storing, and regenerating STL dental data with reduced file sizes and efficient processing times without compromising the accuracy. Clinical Significance: Various STL dental models of patients can be coded, stored, and regenerated to be used again within efficient processing time without affecting the accuracy.","2025-05","2025-04-25 16:49:18","2025-04-25 16:49:18","","","","","156","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Dentistry; Open-source software; 3d data management; accuracy; Blender scripting; Stl file optimization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace.

The framework we proposed is composed of three components, interventions design, democratization, and execution. We believe that this process will work for other FOSS communities too.

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 16:49:19","2025-04-25 16:49:19","","484-510","","","46","","","","","","","","","","English","","","","","","","Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS Type: Article","","","","OSS; Decision Making; Decision Process; F/LOSS; Free/Libre Open Source Software Development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.","2018-05","2025-04-25 16:49:19","2025-04-25 16:49:19","","","","5","10","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","QGIS; remote sensing; global warming; land surface temperature; Landsat-8; semi-automatic classification plugin; urban heat island; urbanization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computational intelligence (CI) in general and particle swarm optimization (PSO) algorithms in particular have been shown to accelerate finding optimal printing parameters. Unfortunately, the implementation of CI has been prohibitively complex for noncomputer scientists. To overcome these limitations, this article develops, tests, and validates PSO Experimenter, an easy-to-use open-source platform based around the PSO algorithm and applies it to optimizing recycled materials. Specifically, PSO Experimenter is used to find optimal printing parameters for a relatively unexplored potential distributed recycling and additive manufacturing (DRAM) material that is widely available: low-density polyethylene (LDPE). LDPE has been used to make filament, but in this study for the first time it was used in the open source fused particle fabrication/fused granular fabrication system. PSO Experimenter successfully identified functional printing parameters for this challenging-to-print waste plastic. The results indicate that PSO Experimenter can provide 97% reduction in research time for 3D printing parameter optimization. It is concluded that the PSO Experimenter is a user-friendly and effective free software for finding ideal parameters for the burgeoning challenge of DRAM as well as a wide range of other fields and processes.","2023-12-01","2025-04-25 16:49:19","2025-04-25 16:49:19","","1287-1300","","6","10","","","","","","","","","","English","","","","","","","Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC Type: Article","","","","fused particle fabrication; LDPE; particle swarm optimization; recycling; waste plastic","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To understand the causes of the differences, we then build game-theoretical models of the contribution situation. Based on these results, we again analyzed the projects empirically to support the outcome of the models, and found empirical evidence. The answers to the initial questions are clear. To incentivize developers to code, the projects should prepare documents, or the projects or third parties should hire developers, and these are what sustainable projects in GitHub did in reality. In addition, making innovations to reduce the writing costs can also have an impact in attracting coding contributors.","2015","2025-04-25 16:49:19","2025-04-25 16:49:19","","15-21","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE COMP SOC; TCSE; ACM; SIGSOFT Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Sometimes interoperability and composition mechanisms provided by component based integration frameworks cannot solve the problem of binary component integration in an automatic way. In this paper we present a technique to allow connectors synthesis for deadlock-free component based architectures [IEEE Proceedings of the 16th ASE, 2001] in the context of COM/DCOM applications. This work also provides guidelines to implement an automatic tool that derives the implementation of routing deadlock-free policies within the connector from the dynamic behavior specification of the COM components. Deadlock is then prevented by inserting the synthesized connector within the system via COM composition mechanisms while letting the system COM servers unmodified. We present a successful application of this technique on the (COM version of the) problem known as “The dining philosophers”. (C) 2002 Elsevier Science Inc.

Most studies, based on a popular FLOSS repository (SourceForge). have concluded that the vast majority of projects are failures. This Study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities ire formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success. (C) 2008 Elsevier Inc.

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways. This may be due primarily to the fact that open source ultimately produces greater value on both the use and production sides, implying an impact on welfare. This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market. To support this, a market concentration index, the HHI index, is tested over the case of web servers. As a result the study reveals that under the appropriate conditions, OSS call have a positive impact on welfare.","2008","2025-04-25 16:49:20","2025-04-25 16:49:20","","1-26","","","","","","","Social Issues Justice and Status","","","","NOVA SCIENCE PUBLISHERS, INC","400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA","English","","","","","","","Type: Article; Book Chapter","","","","","","Stroud, BH; Corbin, SE","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose RecGFI, an effective practical approach for the recommendation of good first issues to newcomers, which can be used to relieve maintainers' burden and help newcomers onboard. RecGFI models an issue with features from multiple dimensions (content, background, and dynamics) and uses an XGBoost classifier to generate its probability of being a GFI. To evaluate RecGFI, we collect 53,510 resolved issues among 100 GitHub projects and carefully restore their historical states to build ground truth datasets. Our evaluation shows that RecGFI can achieve up to 0.853 AUC in the ground truth dataset and outperforms alternative models. Our interpretable analysis of the trained model further reveals interesting observations about GFI characteristics. Finally, we report latest issues (without GFI-signaling labels but recommended as GFI by our approach) to project maintainers among which 16 are confirmed as real GFIs and five have been resolved by a newcomer.","2022","2025-04-25 16:49:20","2025-04-25 16:49:20","","1830-1842","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; Assoc Comp Machinery, Special Interest Grp Software Engn ISSN: 0270-5257 Type: Proceedings Paper","","","","open-source software; onboarding; good first issues","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key factor for the success of a free software project is its development dynamics, dependent on the attraction and retention of users and developers. The license plays an important role in this scenario, because by imposing restrictions on the use of the source code it attracts potential contributors in a different way. The degree of restriction of the license and an indicator of success of free software were related: the time between stages, that is, the time spent to evolve through the various stages of development. The results indicated that projects licensed under non-restrictive terms progress faster than projects licensed under highly restrictive terms and that projects with restrictive licenses progress slower than projects with non-restrictive or highly restrictive licenses.","2015","2025-04-25 16:49:20","2025-04-25 16:49:20","","","","","","","","","","","","","ASSOC INFORMATION SYSTEMS","P.O.

To keep this foundation intact, the open source community needs to actively invest in sustainable approaches to bring in new contributors and nurture existing ones. We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a “rising contributor” badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.","2022","2025-04-25 16:49:20","2025-04-25 16:49:20","","36-40","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery Type: Proceedings Paper","","","","open source; maintainers; social good","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Findings show that UX experts agreed that the lenses could be used with a consensus percentage of 81 %, the threshold value (d) = 0.112, and crisp values greater than alpha-cut = 0.5. On validation, 47.57 % of stakeholders agreed, and 52.43 % strongly agreed they were relevant. Results help evaluate the status quo and change culture and policies toward ideal preparation. Two areas are suggested for future research.","2024-10","2025-04-25 16:49:20","2025-04-25 16:49:20","","","","","237","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","User experience; Free and open-source software; Maturity; Analytical lenses; Fuzzy delphi method; Preparation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors' engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors' attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023-05-01","2025-04-25 16:49:20","2025-04-25 16:49:20","","3106-3130","","5","49","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","Organizations; Task analysis; Mentoring; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; taxonomy; mentoring process; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The success of open source software is known to be attributable to a massive number of contributors engaging in the development process. However, an efficient open source software project is not guaranteed simply by active participation by many; a coordination mechanism is needed to seamlessly manage the multi-party collaboration. On this basis, this study aimed to examine the internal regulatory processes based on Git and GitHub, which serve as such a mechanism, and redefine the efficiency of open source software projects to fully reflect them. For this purpose, a two-stage data envelopment analysis was used to measure the project efficiency reflecting the internal processes. Moreover, this study considered the Kruskal-Wallis test and Tobit regression analysis to examine the effects of the participation by many on an open source software project based on the newly defined efficiency. Results show that a simple increase in contributors can be poisonous in terms of the efficiency of open source software projects.","2018-09","2025-04-25 16:49:20","2025-04-25 16:49:20","","","","9","10","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","GitHub; collaboration; Git; open source software projects; efficiency; data envelopment analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The proposed system utilises the community formed around F/OSS projects to produce meaningful recommendations based on specific user preferences. We suggest that such an approach would overcome some of the difficulties complicating user choice by making useful suggestions and can fit seamlessly within the structure of the majority of F/OSS projects.

It has been reported that less than 10% of Open Source Software (OSS) contributors in GitHub are women. Although related qualitative and quantitative studies point out the gender gap, the technical and social interaction of females within OSS still remain unexplored and largely misunderstood. As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions. Thus, we propose to answer the questions: where are females in OSS projects? How they evolve? and How they contribute to the sustainability of the OSS social capital?. We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity. We found that females are extremely underrepresented within OSS communities, but when they participate they are productive just as males, they evolve following relatively the same patterns than males and remain more involved in projects than males.","2019","2025-04-25 16:49:21","2025-04-25 16:49:21","","308-319","","","","","","","IFIP Advances in Information and Communication Technology","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","Backup Publisher: IFIP WG 5 5 COVE Co Operat infrastructure Virtual Enterprises & Elect Business; Soc Collaborat Networks; Politecnico Torino; Nova Univ Lisbon; UNINOVA; Univ Amsterdam ISSN: 1868-4238 Type: Proceedings Paper","","","","Open Source Software; Social Network Analysis; Diversity; Gender; Socio-Technical interactions","","CamarinhaMatos, LM; Afsarmanesh, H; Antonelli, D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While previous research recognizes the significance of trust in an organizational setting, there is a lack of understanding in how trust is exhibited in OSS distributed teams, where there is an absence of direct, in-person communications. To foster trust and collaboration in OSS teams, we need to understand what trust is and how it is exhibited in written developer communications (e.g., pull requests, chats). In this paper, we first investigate various dimensions of trust to identify the ways trusting behavior can be observed in OSS. Next, we sample a set of 100 GitHub pull requests from Apache Software Foundation (ASF) projects, to analyze and demonstrate how each dimension of trust can be exhibited. Our findings provide preliminary insights into cues that might be helpful to automatically assess team dynamics and establish interpersonal trust in OSS teams, leading to successful and sustainable OSS.","2023","2025-04-25 16:49:21","2025-04-25 16:49:21","","19-24","","","","","","","International Conference on Software Engineering-New Ideas and Emerging Technologies Results Track","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM Special Interest Grp Software Engn; Melbourne Convent Bur; State Govt Victoria; CSIRO; Huawei; Monash Univ; Meta; Google; AWS; Monash Univ; Dragon Testing Technol; IBM; Univ Melbourne; RMIT Univ ISSN: 2832-7624 Type: Proceedings Paper","","","","open source software; trust; pull requests","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Data from semi-structured interviews reveal that company motivations can be categorized into four levels (Founders' Vision, Reputation, Business Advantage, and Reciprocity) and companies participate through different mechanisms (e.g., Developers' Time, Mentoring Time, Advocacy & Promotion Time), each of which tie to the different types of motivations.

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals' early career stages profoundly impact their long-term career success. However, newcomers' early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers' dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers' contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers' early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers' technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers' early careers and hence shed light on future research in this direction.","2023-02-01","2025-04-25 16:49:21","2025-04-25 16:49:21","","529-548","","2","49","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","open source; Task analysis; Ecosystems; Documentation; Engineering profession; Codes; Correlation; Focusing; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These projects often provide onboarding guidelines in their `CONTRIBUTING' files (e.g., CONTRIBUTING.md on GitHub). These files explain, for example, how to find open tasks, implement solutions, and submit code for review. However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions' adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2).

We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file.

Still, all contributors may find it difficult to assimilate into the OSS community even they are enthusiastic to make contributions. We thus suggest that partner recommendation across different roles may benefit both the users and developers, i.e., once we are able to make successful recommendation for those in need, it may dramatically contribute to the productivity of developers and the enthusiasm of users, thus further boosting OSS projects' development. Motivated by this potential, we model the partner recommendation as link prediction task from email data via network embedding methods. In this article, we introduce time-series snapshot network (TSSN) that is a mixture network to model the interactions among users and developers. Based on the established TSSN, we perform temporal biased walk (TBW) to automatically capture both temporal and structural information of the email network, i.e., the behavioral similarity between individuals in the OSS email network. Experiments on ten Apache data sets demonstrate that the proposed TBW significantly outperforms a number of advanced random walk-based embedding methods, leading to the state-of-the-art recommendation performance.","2022-08","2025-04-25 16:49:22","2025-04-25 16:49:22","","1048-1059","","4","9","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","social network; Productivity; Task analysis; Sustainable development; Social networking (online); Data models; Synchronization; open-source software (OSS); Link prediction; network embedding; partner recommendation; random walk; Search problems; temporal network","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, according to the software version sequence, we construct the corresponding developer collaboration network of the Angular OSS community and then analyse this network's structural stability during network evolution. The results show that the network always presents an economical modular small-world structure during its evolution. The maintenance of the structure is related to a cohesive core, which is composed of two types of nodes (i.e., hubs and connectors). The hubs organize noncore nodes to form modules, while connectors facilitate the formation of inter-module connections. The overall results highlight the important role of core developers in the sustainable development of OSS communities and may provide a reference for community initiators to implement protection strategies for core developers.","2022-07-08","2025-04-25 16:49:22","2025-04-25 16:49:22","","","","7","17","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such capstone projects may be student-designed, instructor-designed, designed in conjunction with outside companies, or integrated with ongoing free and open source (FOSS) projects. The literature shows that the FOSS approach has attracted a great deal of interest, in particular when implemented with projects that have humanitarian goals (HFOSS). In this article, we describe five unique models from five distinct types of institutions for incorporating sustained FOSS or HFOSS (alternatively H/FOSS) project work into capstone experiences or courses. The goal is to provide instructors wishing to integrate open source experiences into their curriculum with additional perspectives and resources to help in adapting this approach to the specific needs and goals of their institution and students. All of the models presented are based on sustained engagement with H/FOSS projects that last at least one semester and often more. Each model is described in terms of its characteristics and how it fits the needs of the institution using the model. Assessment of each model is also presented. We then discuss the themes that are common across the models, such as project selection, team formation, mentoring, and student assessment. We examine the choices made by each model, as well as the challenges faced. We end with a discussion how the models have leveraged institutional initiatives and collaborations with outside organizations to address some of the challenges associated with these projects.","2018-07","2025-04-25 16:49:22","2025-04-25 16:49:22","","","","2, SI","18","","","","","","","","","","English","","","","","","","Place: 2 PENN PLAZA, STE 701, NEW YORK, NY 10121-0701 USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","FOSS; Open source; capstones; HFOSS; humanitarian; projects","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model.

In this process is taken into account the emergence of free software which has allowed companies venturing into new ways of performing this reengineering because, by means of collaborative work, they reduced time and costs for many of their processes.","2014-08","2025-04-25 16:49:23","2025-04-25 16:49:23","","197-206","","","42","","","","","","","","","","Spanish","","","","","","","Place: CAMPUS SANTA ROSA DE OSOS, CARRERA 21 NO 34B-07, MEDELLIN, 00000, COLOMBIA Publisher: FUNDACION UNIV CATOLICA NORTE Type: Article","","","","collaborative work; reuse; free software strategies; Process reengineering","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The copyright regime is so restrictive that it turns a normal learning process into a series of potential copyright violations. The Free Software Movement (FSM) represents a substantial community effort to counter this trend. It seeks to supersede the copyright regime by offering the `Copyleft' licensing mode, which facilitates the formation of a cooperative, resource- sharing community. The FSM has been so successful that it has challenged the utilitarian values presumed in copyright law, has fuelled widespread reassessment of copyright law, and has influenced many who engage in various creative activities. Claiming to bear similar values, Creative Commons (CC) provides licensing models for people to waive some rights granted to them. However, CC differs from the FSM in significant ways. Most notably, the flexible CC licensing model weakens the firm philosophical and political ground which binds FSM advocates together. Hence, although CC's rapid growth seems to signal its success, it is questionable whether such success is as enduring as the FSM's, or if it is leading to a different result. While CC champions the author's freedom to decide how to use his or her bundle of property rights granted by copyright law, the FSM advocates the freedom to build and live in an alternative, vital and self- sustaining community. The existence of such an alternative model not only allows these particular participants to be independent from the proprietary world, but also may empower the rest of society to imagine different kinds of relationships between human beings and their creative activities.","2006-12","2025-04-25 16:49:23","2025-04-25 16:49:23","","337-347","","4, SI","4","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We model the individual's chances to become a valuable contributor through her capacity, willingness, and the opportunity to contribute at the time of joining. Using issue tracking data of Mozilla and Gnome, we find that the probability for a new joiner to become a Long Term Contributor (LTC) is associated with her willingness and environment. Specifically, during their first month, future LTCs tend to be more active and show more community-oriented attitude than other joiners. Joiners who start by commenting on instead of reporting an issue or ones who succeed to get at least one reported issue to be fixed, more than double their odds of becoming an LTC. The micro-climate with a productive and clustered peer group increases the odds. On the contrary, the macro-climate with high project popularity and the micro-climate with low attention from peers reduce the odds. This implies that the interaction between individual's attitude and project's climate are associated with the odds that an individual would become a valuable contributor or disengage from the project.

Modeling Participant's Initial Behavior","IEEE TRANSACTIONS ON SOFTWARE ENGINEERING","","0098-5589","10.1109/TSE.2014.2349496","","Motivation: To survive and succeed, FLOSS projects need contributors able to accomplish critical project tasks. However, such tasks require extensive project experience of long term contributors (LTCs). Aim: We measure, understand, and predict how the newcomers' involvement and environment in the issue tracking system (ITS) affect their odds of becoming an LTC. Method: ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. We also reproduced the results on new data provided by Mozilla. Results: We constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants. Newcomers who are able to get at least one issue reported in the first month to be fixed, doubled their odds of becoming an LTC. The macro-climate with high project popularity and the micro-climate with low attention from peers reduced the odds. The precision of LTC prediction was 38 times higher than for a random predictor. We were able to reproduce the results with new Mozilla data without losing the significance or predictive power of the previously published model. We encountered unexpected changes in some attributes and suggest ways to make analysis of ITS data more reproducible. Conclusions: The findings suggest the importance of initial behaviors and experiences of new participants and outline empirically-based approaches to help the communities with the recruitment of contributors for long-term participation and to help the participants contribute more effectively.

However, the stages when developers leave the projects are still weakly explored and are not well-defined in existing developers' lifecycle models. In this position paper, we enrich the knowledge about the leaving stage by identifying sleeping and dead states, representing temporary and permanent brakes that developers take from contributing. We conducted a preliminary set of semi-structured interviews with active developers. We analyzed the answers by focusing on defining and understanding the reasons for the transitions to/from sleeping and dead states.

ESE (endoscopic submucosal excavation) is widely used for the treatment of digestive diseases. The dental floss traction (DFT) method has been successfully used to facilitate ESE to resect mucosal lesions such as early gastric cancer. DFT has not been used in ESE to remove submucosal masses. This study aimed to examine the efficacy of DFT-assisted ESE (DFT- ESE) for the removal of submucous masses. Methods. From March 2017 to May 2017, a total of 12 patients with gastric submucosal masses at the First Affiliated Hospital of Nanchang University, Jiangxi, China, were enrolled. The tumor characteristics, en bloc resection rates, complications, and outcomes on follow-up were evaluated for all patients. Results. The 12 submucosal tumors were completely removed by DFT- ESE. Nine were gastrointestinal stromal tumors. Two were Schwannoma, located in the greater curvature of the gastric corpus. One was gastric ectopic pancreas. All the resected tumors were removed completely with intact tumor capsules. There was no more bleeding or perforation after the endoscopic closure of the perforation or the wound after the DFT-ESE, and no recurrences were identified at the time of follow-up. Conclusions. The DFT method efficiently and safely facilitated the ESE procedure during the resection of gastric submucosal tumors.

Once software complexity is one of the most important attributes to determine software maintainability, controlling its level in the system evolution process makes the software easier to maintain, reducing the maintainability costs. Otherwise, uncontrolled complexity makes the maintenance and enhancement process lengthy, more costly and some times it can contribute to the system abandonment.

Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system's sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries. Specifically, we leveraged a weighted combination of semantics, lexical, and shallow features in conjunction with the Random Forest ensemble learning method. Finally, we discuss the practical applicability of our classifier for mapping and visualizing quality-related concerns into the codebase with an example from the Derby project. To summarize, this work represents an effort and an early awareness to improve the underlying management of issue tracking systems and stakeholder requirements in open-source communities.","2021","2025-04-25 16:49:23","2025-04-25 16:49:23","","12-23","","","","","","","","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors.

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 16:49:24","2025-04-25 16:49:24","","477-512","","4","34","","","","","","","","","","English","","","","","","","Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD Type: Article","","","","Open source software; Enterprise resource planning; Case study; IT adoption; IT risk management; SME","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although industrial applications traditionally rely on PLC-based hardware and, in any case, proprietary software, i.e. operating systems and development tools, in recent years dramatic improvements in hardware computer power and free software quality made realistic the employment of architectures based on PC-compatible hardware and GNU/Linux software, more common in the research community. The advantages of a free infrastructure, that can become the terrain of fruitful cooperation between research institutions and companies, can be exploited mainly in fields, in which the added value is in the application, i.e. in mechanical and algorithmic solutions, and where the point of view is that of aware users of an infrastructure, rather than of R&D competitors. This is the case of the project presented in the following, representing a success story in which the discussion between a research group and a small enterprise led to the identification of the requirements and the joined development of a common software infrastructure. When the project started in 2004, both partners, i.e. the Autonomous robotic systems and control group of CNR-ISSIA and Green Project Srl, had to substitute the obsolete platforms of their marine robots and marking machines for casting products in steelworks with a stable software and hardware infrastructure able of transparently integrating technological improvements while remaining compatible with the past (backward compatibility). On the basis of considerations, discussed below, about system reliability, development and maintenance costs (including human resources), foreseen compatibility and general technical soundness, the choice was to verify the possibility of using standard GNU/Linux for embedded real-time applications. The result is the main technical contribution of this chapter, i.e. the practical demonstration of the possibility of using standard GNU/Linux for implementing embedded real-time control systems working up to a sampling frequency of at most 2 Khz. Furthermore, four years later, the developed system is still demonstrating its capabilities transparently integrating technological improvements and increasing more and more its performance thanks to the new real-time properties of the Linux kernel. A first operative release of the platform was completed in 2005 and integrated with the CNR-ISSIA Charlie unmanned surface vehicle (USV) for robotics research. A second application was the porting to the platform of the software of the control system of Hammer, a steelwork industrial machine used for marking continuous casting products, developed by Greenproject s.r.l. At the moment, the platform is supporting the development of the ALANIS (Aluminium Autonomous Navigator for Intelligent Sampling) USV1 for surface and underwater coastal monitoring. Moreover, the integration with generic field buses and image acquisition systems is being carried out.

The objective of this research is to empirically examine the Brooks' Law in a Free Software context. The principle is separated out into its two primary premises: the first is based on a developer's ability to become productive when joining a new team; the second premise relates to the quality of coordination as the team grows. Three large projects are studied for this purpose: KDE, Plone and Evince. Based on empirical evidence, the paper provides two main contributions: based on the first premise of Brooks' Law, it claims that coordination costs increase only in a very specific phase for Free Software projects. After that, these costs become quasi-constant. Secondly, it shows that a ramp up period exists in Free Software projects, and this period marks the divide between projects that are successful at engaging new contributors from others that only benefit from occasional new contributors.","2009","2025-04-25 16:49:24","2025-04-25 16:49:24","","319-328","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Education studies have also analysed the importance of these communities in spreading and sharing knowledge and educational culture has looked to these organizational forms for inspiration. At the same time, the link between these experiences and the development of pedagogical models emerging from cognitive sciences, systemic theory and the new forms of constructivism, which have generated a fruitful theory/practice circle, has been reinforced. The aim of this paper is to analyse the particular type of organizational, communicative and productive context of Open Communities: Free Software Communities, to understand how they work, their efficacy and to show their close link with dynamics and relations of an educational, formative and didactic type. Learning communities can still learn strategies of communication, organization and socialization from these communities, as well as the value of motivation and the importance of freedom and circulation of knowledge in order to build up efficient communities. We can also gain the understanding that the success of these communities depends on the fact that they are educational communities, therefore education studies can convey values, models and a culture of sharing to other sectors as well, such as the one taken into consideration: Free Software Communities. The study has been conducted with a research methodology of the phenomenological type thanks to a theoretical study and observation of different free software communities, visiting websites, chats, wiki pages, forums and other channels of discussion and collaboration.","2017","2025-04-25 16:49:24","2025-04-25 16:49:24","","8395-8401","","","","","","","EDULEARN Proceedings","","","","IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN","English","","","","","","","ISSN: 2340-1117 Type: Proceedings Paper","","","","Free software; Education Network; Knowledge Sharing; Open Communities","","Chova, LG; Martinez, AL; Torres, IC","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The goal of this endeavor is to represent the many possible steps and/or activities FLOSS participants go through during interactions that can be categorized as learning processes.

It is a clonal B-cell disorder characterized by the proliferation of malignant plasma cells in the bone marrow, the presence of monoclonal serum immunoglobulin, and osteolytic lesions. An increasing amount of evidence shows that the interactions of MM cells and the bone microenvironment play a significant role, suggesting that these interactions may be good targets for therapy. The osteopontin-derived collagen-binding motif-bearing peptide NIPEP-OSS stimulates biomineralization and enhances bone remodeling dynamics. Due to its unique targeted osteogenic activity with a broad safety margin, we evaluated the potential of NIPEP-OSS for anti-myeloma activity using MM bone disease (MMBD) animal models. In a 5TGM1-engrafted NSG model, the survival rates of the control and treated groups were significantly different (p = 0.0014), with median survival times of 45 and 57 days, respectively. The bioluminescence analyses showed that myeloma slowly developed in the treated mice compared to the control mice in both models. NIPEP-OSS enhanced bone formation by increasing biomineralization in the bone. We also tested NIPEP-OSS in a well-established 5TGM1-engrafted C57BL/KaLwRij model. Similar to the previous model, the median survival times of the control and treated groups were significantly different (p = 0.0057), with 46 and 63 days, respectively. In comparison with the control, an increase in p1NP was found in the treated mice. We concluded that NIPEP-OSS delays mouse myeloma progression via bone formation in MMBD mouse models.","2023-04-26","2025-04-25 16:49:24","2025-04-25 16:49:24","","","","9","15","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","bone anabolic agent; bone mineralization; multiple myeloma; multiple myeloma bone disease; NIPEP-OSS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper presents seven case studies of businesses, five of which were founded by people who identify with the free/libre software movement. The result is a theory that small businesses founded by free/libre software advocates have three characteristics of social entrepreneurships. First, social benefit is prioritized over wealth creation. Second, the business's social mission is not incidental but is furthered through its for-pro fit activities, rather than supported by the company's profits. Third, the company's success is de fined in part by the success of its social mission.

During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS. These results suggest that an inter-family succession of Betaproteobacteria occurred in response to colonization by mosses, followed by plants.","2019-09-25","2025-04-25 16:49:24","2025-04-25 16:49:24","","268-277","","3","34","","","","","","","","","","English","","","","","","","Place: C/O DR.

Here, we provide an open travel time matrix dataset that describes travel times between the centroids of all cells in a grid (N = 13,132) covering the metropolitan area of Helsinki, Finland. The travel times recorded in the dataset follow a door-to-door approach that provides comparable travel times for walking, cycling, public transport and car journeys, including all legs of each trip by each mode, such as the walk to a bus stop, or the search for a parking spot. We used the r5py Python package, that we developed specifically for this computation. The data are sensitive to diurnal variations and to variations between people (e.g. slow and fast walking speed).

Meanwhile, software companies have successfully launched programs like Google Summer of Code (GSoC) and FindBugs “fixit” to contribute to open-source projects. Inspired by the success of these programs, we propose GitHub-OSS Fixit, a team-based course project where students are taught to contribute to open-source Java projects by fixing bugs reported in GitHub. We described our course outline to teach students SE concepts by encouraging the usages of several automated program analysis tools. We also included the carefully designed instructions that we gave to students for participating in GitHub-OSS Fixit. As all lectures and labs are conducted online, we think that our course design could help in guiding future online SE courses. Overall, our survey results show that students think that GitHub-OSS Fixit could help them to improve many skills and apply the knowledge taught in class.

In this study, our objective was to advance the practicality of drug-coated floss as an intra gum pocket drug delivery system. The initial design of this delivery system has been previously reported by us. Here, we advance the concept further through in vitro and in vivo evaluation. A floss piece was dip coated in the middle section with model molecules leaving free ends for holding. Porcine gum tissues were used ex vivo and in vivo to evaluate the coated floss, including effect of coating thickness on delivery efficiency, ability to deliver more than one type of molecule (one hydrophilic and one hydrophobic), mechanical properties using a scratch test, and finally retention of delivered material in vivo in the porcine model. After reaching a certain coating thickness, the delivery efficiency of the coated floss decreased, indicating the presence of an optimal coating thickness. Hydrophobic and hydrophilic molecules were successfully coated and delivered with high efficiency into gum pockets. The scratch test indicated that the coatings were resilient. Lastly, the in vivo analysis showed that the drug coating was delivered into the porcine gum pocket with about 65% efficiency, and the coatings could maintain extended residency within the gum pocket despite the native adverse environment of the oral cavity. Overall, this data shows that drug-coated floss can act as a drug delivery vehicle and has potential to provide a minimally invasive and practical method for the delivery of drugs into the gum pockets.","2022-06-29","2025-04-25 16:49:25","2025-04-25 16:49:25","","28663-28670","","25","14","","","","","","","","","","English","","","","","","","Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC Type: Article","","","","floss; coated; drug; gingivitis; gum; mouth; oral cavity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Especially, an embedded OSS known as one of OSS has since been gaining a lot of attention in embedded system area, i. e., Android, BusyBox, etc. However, the poor handling of quality and customer support prohibit the progress of embedded OSS. We focus on the problems in such as software quality which prohibit the progress of embedded OSS. In this paper, we propose a method of software reliability assessment based on a flexible hazard rate model considering the influence of installer application such as App Store of iOS and Android Market of Android OS. Also, we derive several reliability assessment measures. In particular, we show several numerical examples of reliability assessment for our hazard rate model.

These projects carrying out research on MANETs have successfully implemented adhoc networking on few targeted devices, hence implementation of Mobile Adhoc Network (MANET) on every new Android based device is quite challenging in nature. We have researched on Commercial Off the Shelf (COTS) devices (such mobile phones and tablets) to implement adhoc networking using open source software (OSS) such as Serval Mesh, MANET Manager, WiFi Tether applications. We have also modified the TrevE-Mod WiFi Tether application to work successfully with MANET Manager and Linux/ Windows based Personal Computers (PCs) in an adhoc network. The results achieved by performance evaluation tools and testing of VoIP applications have proved it to be satisfactory. We have also satisfactorily implemented, configured and tested point to point Virtual Private Network (VPN) between MANET nodes using OSS (VPN Server, OpenVPN for Android, OpenVPN Connect).

To determine the ideal time to apply an implant after augmentation with Bio-Oss Collagen and to observe if there are differences in the age of the patients and the sex, the aim of this randomized controlled clinical trial was to compare the post-extraction changes in angiogenic and osteogenic aspects during spontaneous bone regeneration with those during socket preservation using Bio-Oss Collagen. Sixty-six patients were included in this study. After 8-12 weeks, bone biopsies were embedded in paraffin and histological and immune-histological investigated. Using qRT-PCR bone (Alpl, Bglap, Runx2) and angiogenic markers (VEGF, caveolin-1) were identified. The histomorphometric analysis of all examined samples showed no differences between treated and untreated sockets, but a tissue compression. After classification in bone regeneration stages, more samples with woven bone were present in treated sockets than in controls. The Alpl expression correlates with increase in mature bone tissue. In treated sockets a significant decrease in CD34 and caveolin-1 protein expression was found. Additionally, a significant increase of Runx2 and VEGF mRNA was detected in patients younger than 50 years. Thus, all specimens showed ossification in different stages after eight weeks of healing. The treated group gives an earlier stage of ossification than controls, but produces densified tissue with greater volume fraction. It can be assumed that successful implant placement in Bio-Oss Collagen augmented extraction sockets is possible after eight weeks of bone healing. (C) 2021 Elsevier B.V.

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.","2014","2025-04-25 16:49:25","2025-04-25 16:49:25","","401-412","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery Special Interest Grp Software Engn; CVIC SE; NSF; Microsoft Res; Huawei; Neusoft; Siemens; Yonyou; Hong Kong Univ Sci & Technol; Google; Radica; Samsung Res Amer; IBM Res; TCL; CCC Type: Proceedings Paper","","","","sequence analysis; layered network; Markov entropy; structural complexity; Time-series","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of minimization reduces differences that might arise by chance between the study arms in the distribution of patient characteristics such as gender, ethnicity and age. However, unlike randomization, minimization requires real time assessment of each new participant with respect to the preceding distribution of relevant participant characteristics within the different arms of the study. For multi-site studies, this necessitates centralized computational analysis that is shared between all study locations. Unfortunately, there is no suitable freely available open source or free software that can be used for this purpose. OxMaR was developed to enable researchers in any location to use minimization for patient allocation and to access the minimization algorithm using any device that can connect to the internet such as a desktop computer, tablet or mobile phone. The software is complete in itself and requires no special packages or libraries to be installed. It is simple to set up and run over the internet using online facilities which are very low cost or even free to the user. Importantly, it provides real time information on allocation to the study lead or administrator and generates real time distributed backups with each allocation. OxMaR can readily be modified and customised and can also be used for standard randomization. It has been extensively tested and has been used successfully in a low budget multi-centre study. Hitherto, the logistical difficulties involved in minimization have precluded its use in many small studies and this software should allow more widespread use of minimization which should lead to studies with better matched control and experimental arms. OxMaR should be particularly valuable in low resource settings.","2014-10-29","2025-04-25 16:49:25","2025-04-25 16:49:25","","","","10","9","","","","","","","","","","English","","","","","","","Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whether a project participant is initiated as a developer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e. g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving developer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e. OSS developers patch submission activities. We use these sets to predict whether a project participant will become a developer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a developer. Further, we find that this is true to the extent that other predictors, e. g. patch submission info, need not be included in the models. In addition, we show that future developers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10% of the three month data's predictions. Finally, we find that it is easier to become a developer earlier in the projects lifecycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2013","2025-04-25 16:49:25","2025-04-25 16:49:25","","340-349","","","","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Software Improvement Grp; Lab Qual Software ISSN: 1063-6773 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play a crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process. In detail, we analyze what review feedbacks encourage a contributor to continue with OSS project. Using a Qt project dataset, we build a prediction model to identify a LTC. We find that not only contributor's activities, but also a reviewer feedbacks, useful in identifying LTCs.","2018","2025-04-25 16:49:25","2025-04-25 16:49:25","","109-113","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IEEE; Int Assoc & Comp & Informat Sci; IEEE Comp Soc Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation. We demonstrate how OSS and systematic conservation planning can be taken to the wider community to produce on-the-fly outputs. Our novel approach has the potential to build partnerships with community groups and give the community a sense of ownership in the decision-making process.

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails. These emails contain decisions for 466 Python Enhancement Proposals (PEPs) that document the language's evolution. Our findings make the influence of different roles transparent to future (new) members, other stakeholders, and more broadly, to the OSS research community.","2021","2025-04-25 16:49:26","2025-04-25 16:49:26","","50-59","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Type: Proceedings Paper","","","","social network analysis; influence; decision-making; Python; Open Source Software (OSS); rationale; onion model; PEP; roles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, that is not the only charge that propels contributions-growing interest in open source has also been attributed to software developers deciding to use their technical skills to benefit a common societal good. To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.","2021","2025-04-25 16:49:26","2025-04-25 16:49:26","","1020-1032","","","","","","","International Conference on Software Engineering","","","","IEEE COMPUTER SOC","10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software Engn; ACM SIGSOFT ISSN: 0270-5257 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We found that although workers valued the flexibility of working from home, they had difficulty focusing on their work for sustained time periods and often felt isolated. This motivated them to use coworking spaces - physical spaces used as work space by workers not on the same team or even the same firm - as a critical part of their space ecology.

This approach re-scales Marchs (1991) framework and applies it to characterize the innovation system of a distributed organization of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two coupled processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from lurking (not contributing or contributing to projects without becoming a member) to laboring (joining one or more projects as members), and to launching (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered developers fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platforms global dynamics.","2008-08","2025-04-25 16:49:26","2025-04-25 16:49:26","","647-710","","4","17","","","","","","","","","","English","","","","","","","Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The National Aeronautics and Space Administration (NASA) Armstrong Flight Research Center (AFRC) (Edwards, California) has been developing an optical fiber-based sensing suite called Fiber Optics Sensing System (FOSS) over the past two decades. Successful strain monitoring flight demonstrations such as the NASA Ikhana (General Atomics, San Diego, California) remotely piloted aircraft and the X-56A Multi-Utility Technology Testbed (Lockheed Martin Corporation, Bethesda, Maryland) remotely piloted subscale aircraft have been performed. Interest in adapting fiber-optic sensors for aerospace applications has led to commissioning the development of a ruggedized FOSS system for spaceflight through the NASA Launch Services Program (LSP) at the NASA Kennedy Space Center (KSC) (Merritt Island, Florida). In this paper, a ruggedized FOSS suitable for a launch environment is discussed in detail. Thermal analysis and enclosure design will be discussed as well as environmental testing such as shock, random vibration, thermal vacuum, and electromagnetic interference/electromagnetic compatibility (EMI/EMC).

In their article, the authors make a strong case that “reset thinking” geared towards a more “sustainable” redesign of the global economy promotes extensive state interventionism and cronyism capitalism, and therefore reject the idea of a need for “a funda-mental rethink of existing management theory”. Whereas I do agree with the authors on most points, I am less convinced that “existing management theory” will suffice to address the problem of “reset thinking”. In this article, I demonstrate that the economy-bias of existing theories is a gateway for “reset thinking” geared towards an allegedly necessary re-/socialisation of management and organisation. A research agenda on cronyism must therefore be complemented by one on privilege and hierarchy not only as undesirable side-effects of cronyism, but also as desired outcomes of advocacy for specific minorities or missions. As self-identifications with group interests or calls for missions have become popular in management theory, I conclude that this new appetite for privilege might undermine not only the higher ideals of many management theorists, but also the foundations of modern society.","2023-09","2025-04-25 16:49:26","2025-04-25 16:49:26","","","","3","39","","","","","","","","","","English","","","","","","","Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Management theory; Conservatism; Cronyism; Restorism; Stratification; The Great Reset","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Deep learning frameworks have been proposed to facilitate the development of such software systems, among which, PYTORCH and TENSORFLOW stand out as notable examples. Considerable attention focuses on exploring software engineering practices and addressing diverse technical aspects in developing and deploying deep learning frameworks and software systems. Despite these efforts, little is known about the open source software communities involved in the development of deep learning frameworks. In this article, we perform a comparative investigation into the open source software communities of the two representative deep learning frameworks, PYTORCH and TENSORFLOW. To facilitate the investigation, we compile a dataset of 2,792 and 3,288 code commit authors, along with 9,826 and 19,750 participants engaged in issue events on GITHUB, from the two communities, respectively. With the dataset, we first characterize the structures of the two communities by employing four operationalizations to classify contributors into various roles and inspect the contributions made by common contributors across the two communities. We then conduct a longitudinal analysis to characterize the evolution of the two communities across various releases, in terms of the numbers of contributors with various roles and role transitions among contributors. Finally, we explore the causal effects between community characteristics and the popularity of the two frameworks. We find that the TENSORFLOW community harbors a larger base of contributors, encompassing a higher proportion of core developers and a more extensive cohort of active users compared to the PYTORCH community. In terms of the technical background of the developers, 64.4% and 56.1% developers in the PYTORCH and TENSORFLOW communities are employed by the leading companies of the corresponding open source software projects, Meta and Google, respectively; 25.9% and 21.9% core developers in the PYTORCH and TENSORFLOW communities possess Ph.D. degrees, while 77.2% and 77.7% contribute to other machine learning or deep learning open source projects, respectively. Developers contributing to both communities demonstrate spatial and temporal similarities to some extent in their pull requests across the respective projects. The evolution of contributors with various roles exhibits a consistent upward trend over time in the PYTORCH community. Conversely, a noticeable turning point in the growth of contributors characterizes the evolution of the TENSORFLOW community. Both communities show a statistically significant decreasing trend in the inflow rates of core developers. Furthermore, we observe statistically significant causal effects between the expansion of communities and retention of core developers and the popularity of deep learning frameworks. Based on our findings, we discuss implications, provide recommendations for sustaining open source software communities of deep learning frameworks, and outline directions for future research.","2025-03","2025-04-25 16:49:26","2025-04-25 16:49:26","","","","3","34","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","GitHub; community evolution; Deep learning; developer classification","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One possible mechanism for learning and knowledge flow is direct watching and observation. This study investigates the impact of co-membership taking into account the alternative mechanism of watching under the setting of OSS development at GitHub. It finds that both co-membership and watching contribute positively to OSS success, and thus shows the co-existence of both experiential learning and vicarious learning for OSS development. Moreover, it finds the impact of co-membership is much stronger than watching.

For this system, the soft-output (SO) detector was recently proposed where a soft-metric (e.g., a log-likelihood ratio (LLR)) is computed from a hard-decision channel output by introducing a novel distance measure in the binary Hamming space. This makes it possible to be naturally incorporated into the state-of-the-art channel codes (e.g., low-density parity-check code or polar code). In this paper, we further improve the performance of the SO detector by exploiting a priori information (e.g., the previously decoded messages), which is called the one-bit successive-cancellation soft-output (OSS) detector. The key idea of the proposed OSS detector is that each user k's message is decoded sequentially via the associated channel decoder k in ascending order and a refined search-space is constructed using the previously decoded messages (i.e., the enhanced LLRs are generated). We then present a multiple OSS detector by taking into account a more practical scenario where the BS is equipped with multiple channel decoders. In addition, we propose an efficient way to determine a good decoding order by introducing a novel set-distance measure. Finally, simulation results demonstrate that the proposed OSS detector can significantly improve the existing SO detector for the coded MU-MIMO systems with one-bit ADCs.","2019","2025-04-25 16:49:26","2025-04-25 16:49:26","","27172-27182","","","7","","","","","","","","","","English","","","","","","","Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Type: Article","","","","Massive MIMO; multiuser MIMO detection; one-bit analog-to-digital converter (ADC); soft-output decoding.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.","2016-05","2025-04-25 16:49:26","2025-04-25 16:49:26","","","","2","25","","","","","","","","","","English","","","","","","","Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY Type: Article","","","","Measurement; natural experiment; Human Factors; commercial involvement; contributor inflow; contributor retention; extent and intensity of involvement; Hybrid project","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to mitigate the impact of natural hazards on European economies and societies, improved risk assessment, and management needs to be pursued. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models have become an important part of flood risk management (FRM). In this context, free and open-source (FOSS) geospatial models provide better and more complete information to stakeholders regarding their compliance with the Flood Directive (2007/60/EC) for effective and collaborative FRM. A geospatial model is an essential tool to address the European challenge for comprehensive and sustainable FRM because it allows for the use of integrated social and economic quantitative risk outcomes in a spatio-temporal domain. Moreover, a FOSS model can support governance processes using an interactive, transparent and collaborative approach, providing a meaningful experience that both promotes learning and generates knowledge through a process of guided discovery regarding flood risk management.

The carriers must integrate their core legacy mainframe operation support systems (OSS) with new generation components that can handle the requirements posed by new service offerings, which means the NG-OSS should pay attention to customers rather than networks. This paper examines the legacy OSS frame with its main component and analysis which part should be weakened or converged, and which part should be enhanced or updated. Then it suggests a more idealized view of a functional OSS architecture that conforms to the concepts of the TeleManagement Forum's Telecom Operations Map (TOM) model. In the last, it discusses bow to evolve the OSS from the network-focused to customers-focused successfully and smoothly.","2008","2025-04-25 16:49:27","2025-04-25 16:49:27","","1207+","","","255","","","","International Federation for Information Processing","","","","SPRINGER","233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES","English","","","","","","","ISSN: 1571-5736 Type: Proceedings Paper","","","","OSS; evolution; operation support systems; telecom service providers","","Xu, LD; Tjoa, AM; Chaudhry, SS","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nonwoven mats with a 1-inch thickness were produced by uniformly arranging milkweed fibers within a mold. Various quantities of fiber were employed to obtain nonwoven mats with a fiber content ranging from 5 to 35 kg/m3. Thermal conductivity and thermal diffusivity were measured across diverse relative humidity levels and temperatures. Simultaneously, milkweed floss samples were exposed to identical environmental conditions to assess the moisture regain and specific heat capacities of the fiber. The specific heat capacity of milkweed and thermal conductivity of the nonwovens exhibited a linear increase with temperature. The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content. The thermal insulation properties of the nonwovens remained partially stable below 30% relative humidity but substantially deteriorated at higher levels. The nonwovens exhibited optimal thermal insulation properties at a fiber content between 20 and 25 kg/m3. The results of this study highlighted several technical advantages of employing milkweed floss as a sustainable and lightweight solution for thermal insulation.","2024-01","2025-04-25 16:49:27","2025-04-25 16:49:27","","","","1","8","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","milkweed floss; nonwoven mat; R-value; seed fibers; specific heat capacity; thermal conductivity; thermal resistance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Core contributors and peripheral contributors work together to create a successful project, each playing a different role. One-Time Contributors (OTCs), who are on the very fringe of the peripheral developers, are largely unstudied despite offering unique insights into the development process. In a prior survey, we identified OTCs and discovered their motivations and barriers. Aims: The objective of this study is to corroborate the survey results and provide a better understand of OTCs. We compare OTCs to other peripheral and core contributors to determine whether they are distinct. Method: We mined data from the same code-review repository used to identify survey respondents in our previous study. After identifying each contributor as core, periphery, or OTC, we compared them in terms of patch size, time interval from submission to decision, the nature of their conversations, and patch acceptance rates. Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate. The peripheral developers fall in between the OTCs and the core contributors. Conclusion: OTCs do, in fact, face the barriers identified in our prior survey. They represent a distinct group of contributors compared to core and peripheral developers.","2017","2025-04-25 16:49:27","2025-04-25 16:49:27","","1-10","","","","","","","International Symposium on Empirical Software Engineering and Measurement","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: ACM; IEEE; IEEE Comp Soc; IBM ISSN: 1938-6451 Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key success factor is to respond to customers' desires to choose the billing scheme that suits their needs, to subscribe to all services as a service package, and to pay for them via a single bill regardless of service type, service location, service providers and network operators. Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task. This paper presents key OSS functions and an information model that tackle this complexity. Challenges are described and requirements are defined. Related efforts are highlighted, and the context surrounding this work is laid out in detail.

It is believed that the seed flosses of common milkweed, Asclepias Syriraca, may be a promising reinforcing fiber given its uncommon hollow microstructure that is associated with both high specific properties and outstanding insulating capacities. This study presents an overview of the properties of milkweed floss and its potential use in reinforced-polymer composites. Milkweed flosses from Quebec were analyzed to determine their overall dimensions, density, porosity, coefficient of acoustic absorption, thermal conductivity, thermal resistance, and elastic modulus. In parallel, a portion of milkweed fibers was treated with acetone to modify their surface, and the properties of the treated fibers were measured and compared against the characteristics of the original fibers. Infrared spectroscopy was employed to assess differences between the chemical groups on the surface of treated and native fibers. The treatment with acetone removed fatty acids, waxes, and free sugars from the fibers' surface. The acetone treatment did not affect the fibers' microstructure nor their acoustic absorption capacity. The acetone-treated fibers showed greater thermal resistance and a higher thermal conductivity than native milkweed floss. The elastic modulus of milkweed decreased by nearly 49% after the acetone treatment.","2023-04-24","2025-04-25 16:49:27","2025-04-25 16:49:27","","","","1","20","","","","","","","","","","English","","","","","","","Place: 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA Publisher: TAYLOR & FRANCIS INC Type: Article","","","","fiber microstructure; mechanical properties; Natural hollow fibers; reinforcing fiber; thermal properties; thermo-acoustic insulation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94% of the surveyed core developers agreed with our state model of inactivity; 71% and 79% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26%, with a similar to 54% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.","2022-05","2025-04-25 16:49:27","2025-04-25 16:49:27","","","","3","27","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Retention; Disengagement; Abandonment; Open-source communities; Repository mining; Turnover","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The recent growth in demand for professional software engineers has led to increased contributions to, and usage of, OSS. However, there is limited understanding of the factors affecting how developers, and how new or student developers in particular, decide which OSS projects to contribute to, a process critical to OSS sustainability, access, adoption, and growth. To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (p < 0.0001, effect size = 0.84), student motivation (p < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (p < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner. Our findings may help improve the experience for new developers participating in OSS4SG and the quality of their contributions. We also hope our work helps educators, project leaders, and contributors to build a mutually-beneficial framework for the future growth of OSS4SG.","2023","2025-04-25 16:49:27","2025-04-25 16:49:27","","3-15","","","","","","","","","","","ASSOC COMPUTING MACHINERY","1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Fdn Software Engn; ACM SIGSOFT; Google; Ant Grp; Meta; JetBrains; ByteDance; Uber; Dragon Testing; Huawei Type: Proceedings Paper","","","","Open Source Software; CS Education; Social Good","","Chandra, S; Blincoe, K; Tonella, P","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whether a project participant is initiated as a committer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e.g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving committer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different Apache Software Foundation OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e., OSS developers' patch submission activities. We use these sets to predict whether a project participant will become a committer, and to characterize their socialization patterns around the time of becoming committer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a committer. Further, we find that this is true to the extent that other predictors, e.g., patch submission info, need not be included in the models. In addition, we show that future committers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10 % of the three month data's predictions. Interestingly, we find that on average, for each project, one's level of socialization ramps up before the time of becoming a committer. After obtaining committer status, their social behavior is more individualized, falling into few distinct modes of behavior. In a significant number of projects, immediately after the initiation there is a notable social cooling-off period. Finally, we find that it is easier to become a committer earlier in the projects life cycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2015-10","2025-04-25 16:49:27","2025-04-25 16:49:27","","1318-1353","","5","20","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article","","","","Open source software; Logistic regression; Developer initiation; Email social networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While code reviews are a common measure to catch bugs during development, they lack scalability, are error-prone, and time-consuming [2,38,41]. Thus, static analysis tools like Semgrep emerged to provide programmatic feedback on code. But static analyses often show low precision, which can jeopardize utility. In this case study, we investigate precision rates for Semgrep OSS for common web weaknesses from the OWASP Top 10 [35]. We explore method and tool limitations in weakness detection, OWASP classes, and Semgrep's public PHP rule set. We apply the latter to 300 open source applications, invest 34 h in manual sample validation, and derive precision rates for each OWASP class. Our validation shows that the rules correctly detected weaknesses for seven OWASP classes with 86% precision, demonstrating the tool's utility. Yet, we estimate that most findings are not exploitable (81%). Thus, there is still considerable assessment overhead for users. Our work further highlights that only a subset of weaknesses are detectable, as dimensions such as runtime context and insecure design remain hidden. Finally, we advise practitioners to not exclusively rely on public rules, as translating application-specific business logic and design choices may open up to the detection of previously uncovered weaknesses.","2024","2025-04-25 16:49:28","2025-04-25 16:49:28","","64-83","","","14828","","","","Lecture Notes in Computer Science","","","","SPRINGER INTERNATIONAL PUBLISHING AG","GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND","English","","","","","","","Backup Publisher: German Informat Soc, Special Interest Grp - Secur Intrus Detect & Response ISSN: 0302-9743 Type: Proceedings Paper","","","","","","Maggi, F; Egele, M; Payer, M; Carminati, M","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It will be shown how a Volume Conductor Model (VCM) is constructed and examined using Python-controlled algorithms for generation, discretization and adaptive mesh refinement of the computational domain, as well as for incorporation of heterogeneous and anisotropic properties of the tissue and allocation of neuron models. The utilization of the platform is facilitated by a collection of predefined input setups and quick visualization routines. The accuracy of a VCM, created and optimized by the platform, was estimated by comparison with a commercial software. The results demonstrate no significant deviation between the models in the electric potential distribution. A qualitative estimation of different physics for the VCM shows an agreement with previous computational studies. The proposed computational platform is suitable for an accurate estimation of electric fields during DBS in scientific modeling studies. In future, we intend to acquire SDA and EMA approval. Successful incorporation of open-source software, controlled by in-house developed algorithms, provides a highly automated solution.

Nevertheless, previous work shows that OSS newcomers often face several barriers to contribute, which lead them to lose motivation and even give up on contributing. A well-known way to help newcomers overcome initial contribution barriers is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in OSS projects. Studying mentors' perspectives on the barriers that newcomers face play a vital role in improving onboarding processes; yet, OSS mentors face their own barriers, which hinder the effectiveness of the strategy. Since little is known about the barriers mentors face, in this paper, we investigate the barriers that affect mentors and their newcomer mentees. We interviewed mentors from OSS projects and qualitatively analyzed their answers. We found 44 barriers: 19 that affect mentors; and 34 that affect newcomers (9 affect both newcomers and mentors). Interestingly, most of the barriers we identified (66%) have a social nature. Additionally, we identified 10 strategies that mentors indicated to potentially alleviate some of the barriers. Since gender-related challenges emerged in our analysis, we conducted nine follow-up structured interviews to further explore this perspective. The contributions of this paper include: identifying the barriers mentors face; bringing the unique perspective of mentors on barriers faced by newcomers; unveiling strategies that can be used by mentors to support newcomers; and investigating gender-specific challenges in OSS mentorship. Mentors, newcomers, online communities, and educators can leverage this knowledge to foster new contributors to OSS projects.","2018-12","2025-04-25 16:49:28","2025-04-25 16:49:28","","679-714","","3-6, SI","27","","","","","","","","","","English","","","","","","","Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER Type: Article; Proceedings Paper","","","","Onboarding; Open source software; Challenges; Coach; Difficulties; Joining process; Mentor; Newbie; Newcomer; Novice; Obstacles; Tutor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To understand why OTCs have not contributed another patch and provide guidance to FLOSS projects on retaining OTCs, this study seeks to understand the impressions, motivations, and barriers experienced by OTCs. We conducted an online survey of OTCs from 23 popular FLOSS projects. Based on the 184 responses received, we observed that OTCs generally have positive impressions of their FLOSS project and are driven by a variety of motivations. Most OTCs primarily made contributions to fix bugs that impeded their work and did not plan on becoming long term contributors. Furthermore, OTCs encounter a number of barriers that prevent them from continuing to contribute to the project.

Using social capital theory in a mixed methods case study, we compare entrepreneur and non-entrepreneur behaviors to investigate how entrepreneurs build social capital within an OSS community. This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation). Given the liabilities of newness and smallness as well as other challenges faced by entrepreneurs, applying an open innovation strategy in OSS communities could be one approach where entrepreneurs, by developing and freely revealing their intellectual property to the community, share their way to success via OSS-infused entrepreneurial business ventures.","2019-03","2025-04-25 16:49:28","2025-04-25 16:49:28","","23-40","","1","29","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Social capital; Entrepreneurship; Mixed methods case study; OSS Online communities; Virtual worlds","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As a first implementation, it is assumed that the forward models are perfect and that the radar data are sampled at the analysis grid points. A general purpose nonhydrostatic compressible model is used with the inclusion of complex multiclass ice microphysics. New aspects of this study compared to previous work include the demonstration of the ability of the EnKF method to retrieve multiple microphysical species associated with a multiclass ice microphysics scheme, and to accurately retrieve the wind and thermodynamic variables. Also new are the inclusion of reflectivity observations and the determination of the relative role of the radial velocity and reflectivity data as well as their spatial coverage in recovering the full-flow and cloud fields. In general, the system is able to reestablish the model storm extremely well after a number of assimilation cycles, and best results are obtained when both radial velocity and reflectivity data, including reflectivity information outside of the precipitation regions, are used. Significant positive impact of the reflectivity assimilation is found even though the observation operator involved is nonlinear. The results also show that a compressible model that contains acoustic modes, hence the associated error growth, performs at least as well as an anelastic model used in previous EnKF studies at the cloud scale. Flow-dependent and dynamically consistent background error covariances estimated from the forecast ensemble play a critical role in successful assimilation and retrieval. When the assimilation cycles start from random initial perturbations, better results are obtained when the updating of the fields that are not directly related to radar reflectivity is withheld during the first few cycles. In fact, during the first few cycles, the updating of the variables indirectly related to reflectivity hurts the analysis. This is so because the estimated background covariances are unreliable at this stage of the data assimilation process, which is related to the way the forecast ensemble is initialized. Forecasts of supercell storms starting from the best-assimilated initial conditions are shown to remain very good for at least 2 It.","2005-07","2025-04-25 16:49:28","2025-04-25 16:49:28","","1789-1807","","7","133","","","","","","","","","","English","","","","","","","Place: 45 BEACON ST, BOSTON, MA 02108-3693 USA Publisher: AMER METEOROLOGICAL SOC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Clinically used natural substitute inorganic bovine bone mineral (Bio-Oss) bone powder lacks high compactibility and efficient osteo-inductivity that limit its clinical application in repairing large bone defects. In this study, a poly ethylene glycol/hyaluronic acid (PEG/HA) hydrogel was used to stabilize Bio-Oss and incorporate rat bone marrow stem cell-derived sEVs (rBMSCs-sEVs) to engineer a PEG/HA-Bio-Oss (PEG/HA-Bio) composite scaffold. Encapsulation and sustained release of sEVs in hydrogel scaffold can enhance the retention of sEVs in targeted area, achieving long-lasting repair effect. Meanwhile, synergistic administration of sEVs and Bio-Oss in cranial defect can improve therapeutic effects. The PEG/HA-Bio composite scaffold showed good mechanical properties and biocompatibility, supporting the growth of rBMSCs. Furthermore, sEVs enhanced in vitro cell proliferation and osteogenic differentiation of rBMSCs. Implantation of sEVs/PEG/HA-Bio in rat cranial defect model promoted in vivo bone regeneration, suggesting the great potential of sEVs/PEG/HA-Bio composite scaffold for bone repair and regeneration. Overall, this work provides a strategy of combining hydrogel composite scaffold systems and stem cell-derived sEVs for the application of tissue engineering repair.","2024-11-01","2025-04-25 16:49:28","2025-04-25 16:49:28","","","","6","19","","","","","","","","","","English","","","","","","","Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP Publishing Ltd Type: Article","","","","Bio-Oss; bone defects; PEG/HA hydrogel; rBMSC; small extracellular vesicles; tissue engineering","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better. Interestingly, the final decision was perceived negatively in nine cases and positively in seven cases, while in the remaining cases it was perceived as neither positive nor negative.","2018-03","2025-04-25 16:49:28","2025-04-25 16:49:28","","237-261","","3","44","","","","","","","","","","English","","","","","","","Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC Type: Article","","","","Decision making; OSS; outsourcing; COTS; in-house","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It was noteworthy that the regeneration of alveolar bone was rapidly promoted to be shortened from the ordinary 3 months to 2 weeks. The nanoparticles designed by us according to the oral environment could protect microRNA from various enzymes and electrolytes attack, leading to a steady, continuous, and efficient delivery of gene. With the aid of porous Bio-Oss, microRNA-21 released in situ and its effects on highly reducing the recovery time and improving the quality of newly formed bone at the alveolar site were confirmed for the first time.

Therefore, the use of biomaterials/scaffolds for maxillofacial bone regrowth has been attracting great interest from many surgical specialties and experts. Many approaches have been devised in order to create an optimal bone scaffold capable of achieving desirable degrees of bone integration and osteogenesis. Osteogenesis represents a complex physiological process involving multiple cooperating systems. A tight relationship between the immune and skeletal systems has lately been established using the concept of “osteoimmunology,” since various molecules, particularly those regulating immunological and inflammatory processes, are shared. Inflammatory mediators are now being implicated in bone remodeling, according to new scientific data. In this study, a profiler PCR array was employed to evaluate the expression of cytokines and chemokines in human adipose derived-mesenchymal stem cells (hASCs) cultured on porous hydroxylapatite (HA)/Collagen derived Bio-Oss((R))/Avitene scaffolds, up to day 21. In hASCs grown on the Bio-Oss((R))/Avitene biomaterial, 12 differentially expressed genes (DEGs) were found to be up-regulated, together with 12 DEG down-regulated. Chemokine CCL2, which affects bone metabolism, tested down-regulated. Interestingly, the Bio-Oss((R))/Avitene induced the down-regulation of pro-inflammatory inter-leukin IL-6. In conclusion, our investigation carried out on the Bio-Oss((R))/Avitene scaffold indicates that it could be successfully employed in maxillofacial surgery. Indeed, this composite material has the advantage of being customized on the basis of the individual patients favoring a novel personalized medicine approach.","2022-06-27","2025-04-25 16:49:28","2025-04-25 16:49:28","","","","","10","","","","","","","","","","English","","","","","","","Place: AVENUE DU TRIBUNAL FEDERAL 34, LAUSANNE, CH-1015, SWITZERLAND Publisher: FRONTIERS MEDIA SA Type: Article","","","","biomaterial; chemokine; cytokine; immunomodulation; osteogenic differentiation; stem cells","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Cavities were formed, by a homemade mold, on untouched third molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities' surface and their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three materials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential morphology. Moreover, variations were observed when comparing cells numbers on cavity's filling versus the surrounding dentine disc. The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss. This was confirmed in the migration assay where a statistically significant lower number of cells migrated towards Bio-Oss as compared to MTA and dentin chips.

In order to effectively promote the growth of online secondhand markets, this paper designs and validates a scale to assess customer perception of the service quality of secondhand products purchased via online platforms. Complementarily, the paper assesses how each of the different dimensions that configure the scale contributes to explaining the fulfillment of customers' expectations. The scale is defined by 23 items and is arranged in 5 dimensions from the literature on online commerce as well as on the sharing economy. A sample of 200 questionnaires is used for exploratory factor analysis. A second sample of 507 users is used for confirmatory factor analysis. The quality perceived by online customers of secondhand products depends on the quality of the interactions that they have with the website, with the vendor, and with the product. The dimension that contributes the most to customer fulfillment of expectations is product quality. Findings identify the items that contribute the most to quality perception and fulfillment of expectations, facilitating the development of more effective strategies for platform owners and vendors who want to attract and retain customers of secondhand products. Complementarily, these findings are useful to businesses and governments that want to promote a more sustainable economy by reducing consumption of new products and promoting reutilization of existing ones.","2020-11","2025-04-25 16:49:29","2025-04-25 16:49:29","","","","21","12","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","online; quality; fulfillment of expectations; secondhand","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: Sixty-eight patients who had difficulty in cannulation into the papilla located at the lower, left, or right side of the periampullary diverticulum upon endoscopic retrograde cholangiopancreatography (ERCP) were recruited at Taizhou Hospital from July 2016 to June 2020. A random number table was used to divide the patients into an intervention (with titanium clip-dental floss traction) group and a control group (n=34 in each group). Patients in both groups underwent ERCP. The cannulation time, cannulation success rate, incidence of postprocedural complications after ERCP, hospitalization time, and hospitalization expenses in the 2 groups were compared. Result: The cannulation time was 15.3 +/- 4.1 minutes in the intervention group, which was less than that in the control group (25.7 +/- 6.5 min). The cannulation success rate was 77 +/- 12.1% in the intervention group, which was higher than that in the control group (43 +/- 16.7%). Postprocedural complications occurred in 2 patients in the intervention group and 6 patients in the control group, with no significant differences. The hospitalization time and expenses were 3.8 +/- 2.6 days and 11.1 +/- 6 thousand yuan in the intervention group, respectively, and 6.1 +/- 3.7 days and 18.2 +/- 8 thousand yuan in the control group, respectively. The differences were statistically significant (P<0.05). Conclusion: Titanium clip-dental floss traction-assisting endoscopy achieved excellent efficacy in patients with difficulty in cannulation into the papilla located at the lower, left or right side of the periampullary diverticulum. The cannulation success rate was improved after treatment, with good safety and prognosis.","2022-08","2025-04-25 16:49:29","2025-04-25 16:49:29","","462-465","","4","32","","","","","","","","","","English","","","","","","","Place: TWO COMMERCE SQ, 2001 MARKET ST, PHILADELPHIA, PA 19103 USA Publisher: LIPPINCOTT WILLIAMS & WILKINS Type: Article","","","","duodenal peridiverticular papilla; ERCP; prognosis; titanium clip-dental floss traction","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

From August to November 2014, a total of 95 patients with 104 gastric epithelial neoplasms underwent DFC-ESD (DFC group). Historical controls treated by conventional ESD (control group) were individually matched to cases at a 1:1 ratio by lesion location, ulcer findings, resected specimen size, and the proficiency of the operator (trainee/expert). The outcomes of the procedure in the two groups were then compared. The mean +/- A SD procedure time was 43 +/- A 24 min in the DFC group and 52 +/- A 30 min in the control group (P < 0.01). Fewer lesions in the DFC group needed > 80 min compared with the control group (3-vs-16 cases, P = 0.01). There were no significant differences in adverse events between the groups. Perforation and delayed bleeding occurred in one and four lesions, respectively, in the DFC group, and three and nine in the control group. En bloc resection was achieved in all cases. No significant differences were found regarding curability of ESD between the groups. DFC effectively reduced ESD procedure time without increasing adverse events.

Considering that traditional salinity reconstruction methods often suffer from various factors such as additional constraints, priori physical assumptions and large of specific regression coefficients, a generative adversarial networks (GANs) based deep learning (DL) framework is proposed to directly construct a near real-time, high-resolution daily three-dimensional ocean subsurface salinity (3D OSS) dataset from a data driven perspective in this study. Four models with different structural combinations are designed in the China's marginal seas. Experimental results demonstrate that the models can successfully reconstruct the high-precision and high-resolution 3D OSS on a daily scale in 12 depth levels (from 2 m to 200 m). The asymmetric inception3DGAN model with all enhanced structures has the highest accuracy, the average root-mean-squared error (RMSE) is 0.135psu, the average coefficient of determination (R2) is 0.5641 and the percent bias is 0.436%. Comparing with model without enhanced structures, the average RMSE is decreased by 22.41% when adding all the enhancement structures. Besides, temporal and spatial error analysis are also conducted to evaluate the models' performance from different aspects. Finally, the model results are used to analyze common ocean elements, such as water mass properties, dynamic fields and geostrophic velocity fields, demonstrating that the 3D OSS dataset construction approach proposed in this study not only provides some new insights into ocean observations, but also has high application values.","2023-08","2025-04-25 16:49:29","2025-04-25 16:49:29","","","","","184","","","","","","","","","","English","","","","","","","Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD Type: Article","","","","Deep learning; Data-driven; Generative adversarial networks; Ocean subsurface salinity; T-S mapping","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Increasingly complex simulations are used to assess similarities and differences between the two models' components. The simulations presented here are forced by ocean currents from a Finite Volume Community Ocean Model (FVCOM) implementation that has excellent skill in representing tidal motion, and with observed wind data that compensates for a coarse vertical ocean model resolution. The comprehensive comparison between GNOME and BLOSOM presented here, should aid modelers in interpreting their results. Beyond many similarities, aspects where both models are distinct are highlighted. Some suggestions for improvement are included, e.g., the inclusion of temporal interpolation of the forcing fields (BLOSOM) or the inclusion of a deflection angle option when parameterizing wind-driven processes (GNOME). Overall, GNOME and BLOSOM perform similarly, and are found to be complementary oil spill models. This paper also sheds light on what drove the historical Point Wells spill, and serves the additional purpose of being a learning resource for those interested in oil spill modeling. The increasingly complex approach used for the comparison is also used, in parallel, to illustrate the approach an oil spill modeler would typically follow when trying to hindcast or forecast an oil spill, including detailed technical information on basic aspects, like choosing a computational time step. We discuss our successful hindcast of the 2003 Point Wells oil spill that, to our knowledge, had remained unexplained. The oil spill models' solutions are compared to the historical Point Wells' oil trajectory, in time and space, as determined from overflight information. Our hindcast broadly replicates the correct locations at the correct times, using accurate tide and wind forcing. While the choice of wind coefficient we use is unconventional, a simplified analytic model supported by observations, suggests that it is justified under this study's circumstances. We highlight some of the key oceanographic findings as they may relate to other oil spills, and to the regional oceanography of the Salish Sea, including recommendations for future studies.","2018-09","2025-04-25 16:49:29","2025-04-25 16:49:29","","","","3","6","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","BLOSOM; Foss Barge; GNOME; hindcast; model comparison; ocean trajectory; oil spill model; Point Wells; Salish Sea; windage","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The Digital Video Broadcast Return Channel Satellite (DVB-RCS) NetOps vision for remote management and monitoring aims to provide visibility and Situational Awareness to required communities of interest as well as the ability to view and configure all the operational layers DVB-RCS, including the devices and technology, operations and management, and missions and objectives. An effective management and monitoring solution for DVB-RCS must provide the capability to centrally manage and monitor the system, interoperate between SATCOM and terrestrial networks, consolidate technology, standardize processes, and be proactive rather than reactive. The DISN OSS is DISA's enterprise-wide Service Oriented Architecture for information sharing, management, and monitoring capabilities, based on the Telecommunications Management Network industry standards. The DISN OSS puts the information into the hands of the operators and system managers while making the processes, tools, and technology transparent to the consumer.

In this paper, I intend to examine some of the self-conscious ambiguities of the role-playing narrator of The Mill on the Floss. The use of the male narrator is inseparably bound up with a number of compromises for the woman writer and for the female reader. But being thus `compromised' through vicariously living the experience of the masculine Other also allows the woman writer privileged insight into the complex processes of justification and rationalisation through which the masculine world-view is engendered and sustained in narrative; it allows her imaginatively to work through, and to see through, the tangle of cause and effect relations which are often illegitimately marshalled into support of that view, and to cast ironical and critical light on them.","2004-04","2025-04-25 16:49:29","2025-04-25 16:49:29","","230-250","","59","","","","","","","","","","","English","","","","","","","Place: CAHIERS VICTORIENS EDOUARDIENS PO 5043, 34032 MONTPELLIER-CEDEX, FRANCE Publisher: UNIV PAUL VALERY Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Satellite remote sensing is the optimal tool to provide such data. Images from Synthetic Aperture Radar (SAR) satellite sensors are preferably used as they work regardless of cloud coverage during image acquisition. However, processing of SAR is more complicated and the sensors have development potential. Dealing with such a complexity, current studies should aim to be reproducible, open, and built upon free and open-source software (FOSS). Thereby, the data can be reused to develop and validate new algorithms or improve the ones already in use. This paper presents a case study of crop classification from microwave remote sensing, relying on open data and open software only. We used 70 multitemporal microwave remote sensing images from the Sentinel-1 satellite. A high-resolution, high-precision digital elevation model (DEM) assisted the preprocessing. The multi-data approach (MDA) was used as a framework enabling to demonstrate the benefits of including external cadastral data. It was used to identify the agricultural area prior to the classification and to create land use/land cover (LULC) maps which also include the annually changing crop types that are usually missing in official geodata. All the software used in this study is open-source, such as the Sentinel Application Toolbox (SNAP), Orfeo Toolbox, R, and QGIS. The produced geodata, all input data, and several intermediate data are openly shared in a research database.

However, no traction method using the thread and clip for duodenal ESD as described in this article has been reported to date. We report a case in which traction-assisted ESD using dental floss and a clip was successfully performed on a huge superficial nonampullary duodenal epithelial tumor accompanied by severe fibrosis caused by preoperative biopsies. A 65-year-old woman had a 55-mm flat-elevated tumor in the second part of the duodenum. Severe fibrosis of the submucosal layer was expected due to repeated biopsies at the same site by the patient's previous endoscopist. We selected ESD for this lesion, and the initial incision was started from the side proximal to the lesion, but it was difficult to insert the scope under the submucosal layer directly beneath the biopsy scar. Therefore, traction with an endoclip and dental floss was performed to lift the lesion. Excellent traction allowed safe resection of the fibrotic part under accurate visual observation. Finally, the lesion was resected en bloc without adverse events. Traction-assisted ESD using dental floss and a clip is likely to be an effective adjunctive technique for quick, safe, and successful resection of lesions in the duodenum on which it is difficult to perform ordinary ESD and that have a high probability of intraoperative perforation and massive bleeding.","2019-04","2025-04-25 16:49:29","2025-04-25 16:49:29","","179-181","","2","3","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","dental floss; duodenal endoscopic submucosal dissection; severe fibrosis; superficial nonampullary duodenal epithelial tumor; traction-assisted endoscopic submucosal dissection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bio-Oss (R) is a deproteinized, sterilized bovine bone that has been extensively used in bone regeneration procedures. The aim of the present study was a comparative light, scanning, and electron microscopy evaluation of the interface between Bio-Oss (R) and bone in specimens retrieved after sinus augmentation procedures. Under light microscopy, most of the particles were surrounded by newly formed bone, while in a few cases, at the interface of some particles it was possible to observe marrow spaces and biological fluids. Under scanning electron microscopy, in most cases, the particle perimeter appeared lined by bone that was tightly adherent to the biomaterial surface. Transmission electron microscopy showed that the bone tissue around the biomaterial showed all the phases of the bone healing process. In some areas, randomly organized collagen fibers were present, while in other areas, newly formed compact bone was present. In the first bone lamella collagen fibers contacting the Bio-Oss (R) surface were oriented at 243.73 +/- 7.12 degrees (mean +/- SD), while in the rest of the lamella they were oriented at 288.05 +/- 4.86 degrees (mean +/- SD) with a statistically significant difference of 44.32 degrees (p < 0.001). In the same areas the intensity of gray value was 172.56 +/- 18.15 (mean +/- SD) near the biomaterial surface and 158.71 +/- 21.95 (mean +/- SD) in the other part of the lamella with an unstatistically significant difference of 13.79 (P = 0.071). At the bone-biomaterial interface there was also an electron-dense layer similar to cement lines. This layer had a variable morphology being, in some areas, a thin line, and in other areas, a thick irregular band. The analyses showed that Bio-Oss (R) particles do not interfere with the normal osseous healing process after sinus lift procedures and promote new bone formation. In conclusion, this study serves as a better understanding of the morphollogic characteristics of Bio-Oss (R) and its interaction with the surrounding tissues.

Preliminary method for the A50 road link (Eindhoven-Oss, The Netherlands)","ECOLOGICAL ENGINEERING","","0925-8574","10.1016/S0925-8574(96)00024-9","","After years of efforts to avoid or reduce the impact of infrastructure projects on nature, the principle of ecological compensation has been incorporated in Dutch governmental policy. Ecological compensation aims to recover those ecological functions and natural values that still remain affected after maximum effort has been made to reduce the impact of the intervention (mitigation). The accepted aim of current policy is thus no-net-loss of area and quality by means of mitigative and compensatory measures. As part sf the planning process for construction of a stretch of road in The Netherlands, viz,, the A50 road link in the province of North Brabant, a Nature Compensation Plan (NCP) was required to be drawn up. This work has recently been completed by the Regional Directorate of Public Works and Water Management, the initiator of the intervention. The NCP, initially presented as a Draft Plan, was drawn up by the Regional Directorate using a preliminary method designed by the Centre of Environmental Science of Leiden University for deriving compensatory measures. After an opportunity for public comment, the Draft Plan was revised to form a Final NCP. This article describes, firstly, the preliminary method for deriving ecological compensatory measures. The method starts by quantifying the effects of habitat loss, habitat disturbance (by changes in noise emissions, in the water table and in outdoor recreational patterns), barrier action and fauna casualties. Following mitigation of impacts on nature, compensation for non-mitigable effects focuses successively on area size, derived from the impact on breeding birds, and on area quality, derived from the habitat requirements of the vegetation and fauna groups affected by the road. Guidelines for identifying appropriate locations for compensation are also formulated. Secondly, the compensation method is applied to calculate the mitigative and compensatory measures for the A50 trajectory between Eindhoven and Oss. Thirdly, two comparisons are made: the Draft NCP is compared with the results of the preliminary method, and the Draft and the Final NCP are compared with one another in order to identify the role of the interest groups that played a major role in commenting on the Draft Plan. Finally, realization of the compensatory measures and development of the preliminary method itself are discussed. On the basis of the experience with the A50 case study, a more robust compensation method for road projects is to be developed.","1996-12","2025-04-25 16:49:29","2025-04-25 16:49:29","","327-349","","4","7","","","","","","","","","","English","","","","","","","Place: PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS Publisher: ELSEVIER SCIENCE BV Type: Article; Proceedings Paper","","","","mitigation; barrier action; fauna casualties; habitat disturbance; habitat loss; no-net-loss of area and quality; road infrastructure","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of present study was to fully characterize our anorganic bone, InterOss (R), by physical and chemical methods and to compare it with another anorganic bone, Bio-Oss (R) that has been commercially distributed in dental bone graft substitute market since 1995. InterOss (R) anorganic bone had been successfully prepared by chemical treatment (NaOH and H2O2) and low temperature (350 degrees C) annealing process with an extremely low heating rate (<0.3 degrees C min(-1)). Commercially available Bio-Oss (R) anorganic bone was chosen for comparison. The physical and chemical analysis indicated that the pore structure, microstructure, phase structure, and chemical composition of InterOss (R) is substantially equivalent to that of Bio-Oss (R). The BET analysis also showed that the inner surface area of InterOss (R) is comparatively higher than that of Bio-Oss (R). Specially, the protein analysis showed that the content of residual protein of InterOss (R) is relatively lower than that of Bio-Oss (R). Based on an equivalency to Bio-Oss (R) in terms of physical and chemical characterization with both higher inner surface area and lower residual protein content, the InterOss (R) can be a promising candidate as dental bone grafting material in periodontal and maxillofacial surgery.

The antioxidant tea polyphenol (TPP) was embedded into W/O microemulsion, which was further encapsulated into multiple emulsion (Multi-E) together with functional soluble dietary fiber (SDF). The physicochemical properties indicated that the nanoemulsion-based edible film (NEF) improved the morphology of FF and reduced the crystallinity of the film by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water vapor permeability increased gradually and rose to only 0.99% after 5 h, resulting in the water activity of FF at a low level (<= 0.51) during the storage period. The TPP inside was released at a constant rate (<= 18.10%) on the surface, and such a rate was accelerated in the simulated gastrointestinal environment, especially in intestine reaching 60.12% after 5 h of digestion. Besides, the effect of NEF on the flavor was also evaluated and the contents of ketones, phenols, and pyrazines increased, which displayed a regulating effect on the overall flavor of FF by blocking the external moisture and suppressing the microorganism activity. In summary, the NEF effectively enhanced the flavor and taste of FF, controlled the release of TPP, and reduced the water activity during the storage, thereby extending the shelf life.","2022-07","2025-04-25 16:49:30","2025-04-25 16:49:30","","2370-2380","","7","10","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","controlled release; fish floss; nanoemulsion-based edible coating; shelf life; water activity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Generalized refractory chronic periodontitis is a periodontal condition that is resistant to conventional therapy. Management of this condition often is frustrating to both the patient and the clinician. Case Descriptions. The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. Conclusions and Practical Implications. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.","2016-12","2025-04-25 16:49:30","2025-04-25 16:49:30","","974-978","","12","147","","","","","","","","","","English","","","","","","","Place: 211 E CHICAGO AVE, CHICAGO, IL 60611 USA Publisher: AMER DENTAL ASSOC Type: Article","","","","dental floss; allergy; chronic periodontitis; contact hypersensitivity; plasma cell; Treatment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various types of bone graft materials are used after a sinus lift. In our study, a three-dimensional image analysis using a volume analyzer was performed to measure and compare the volume of demineralized bovine bone mineral (Bio-Oss (R)) and carbonate apatite (Cytrans (R)) after a sinus lift, as well as the amount of bone graft material resorption. Patient data were collected from cone-beam computed tomography images taken before, immediately following, and 6 months after the sinus lift. Using these images, both the volume and amount of resorption of each bone graft material were measured using a three-dimensional image analysis system. Results The amount of bone resorption in the Bio-Oss (R)-treated group was 25.2%, whereas that of the Cytrans (R)-treated group was 14.2%. A significant difference was found between the two groups (P < 0.001). Conclusions Our findings indicate that the volume of bone resorption was smaller in the Cytrans (R)-treated group than in the Bio-Oss (R)-treated group, suggesting that Cytrans (R) is more promising for successful implant treatments requiring a sinus lift.","2021-03-23","2025-04-25 16:49:30","2025-04-25 16:49:30","","","","1","7","","","","","","","","","","English","","","","","","","Place: SHIROYAMA TRUST TOWER 5F, 4-3-1 TORANOMON, MINATO-KU, TOKYO, 105-6005, JAPAN Publisher: SPRINGER JAPAN KK Type: Article","","","","Bio-Oss® CBCT; Cone-beam computed tomography; Cytrans® Dental implant; Maxillary sinus augmentation; Sinus lift","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The clip with line traction method was reported to improve ESD. However, there was no comparison with conventional ESD especially for trainees. We report here on the feasibility and efficacy of traction using dental floss with endoscopic clip to facilitate ESD versus conventional method for ESD trainees. Twenty simulated gastric lesions, paired with location and size, were created in porcine stomachs using a standard template. After a circular incision was made, submucosal dissection (control, n = 10) was performed with standard ESD, while the study (clip, n = 10) was performed with traction using dental floss and endoclip. Primary outcome was speed of submucosal dissection. Secondary outcome included frequency of submucosal injection and adverse event. Compared with controls, median procedure time was significantly shorter in the clip group (5.6 +/- A 1.1 vs. 13.6 +/- A 2.5 min, P = 0.003), with a significantly faster submucosal dissection time (1.8 +/- A 0.3 vs. 0.6 +/- A 0.1 cm(2)/min, P = 0.001) and less frequent submucosal injection (5.7 +/- A 0.6 vs. 8.5 +/- A 1.0 times, P = 0.024).

The purpose of this study was to radiologically evaluate the efficacy of using Bio-Oss Collagen with Concentrated Growth Factor (CGF) as grafting materials for OSFE with simultaneous implant placement in the atrophic maxilla after one year of functional loading.MethodsA total of 126 implants were placed for 123 patients. Our inclusion criteria were patients with Residual Bone Height (RBH) <= 5 whom underwent OSFE procedure and simultaneous implant placement with different grafting materials: Group A with no grafting materials, Group B with Bio-Oss bone graft, and Group C with Bio-Oss Collagen with CGF. The Implants Survival Rate (ISR) was the primary outcome variable. Secondary outcome variables included radiographic measurements assessed at four follow-up time points, the Implant Stability Quotient (ISQ), and bone density (B). Indicators of bone formation were compared at different time points. Appropriate statistical analyses were conducted, with statistical significance set at a P value of 0.05 for all tests.ResultsISR was 96%. A significant positive relationship was found between RBH and ISR, [r (126) = .359, p = .000]. Endo sinus bone gain indictors increased in both grafted groups as compared to the non-grafted group. Total Bone Resorption (TBR1) and (TBR2) significantly decreased in both grafted groups compared to the non-grafted group (P = .004, P = .000). Graft size (D) was a positive predictor for ISR at three time points: D0 (odds ratio [OR] 8.06; 95% CI 1.59 to 38.24; P = .010); D1 (OR 96.58; 95% CI 1.69 to 5.52; P = .027); D2 (OR 4.97; 95% CI 1.29 to 19.19; P = .020). Visual Analog Scale (VAS) pain score significantly increased in Group B compared to Groups A and C (P = .000).ConclusionThe combination of Bio-Oss Collagen with CGF as grafting material is a reliable protocol after OSFE with simultaneous implant placement in the atrophic maxilla.

With advances in digital planning, surgical techniques, orthognathic surgery becomes increasingly safe, however, still a physiological factor that challenges the surgeon: bone repair. The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss (R) Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss (R)) and 10% collagen fibres in a block form and is sterilized by gamma-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss (R) Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss (R) Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.","2023-09-10","2025-04-25 16:49:30","2025-04-25 16:49:30","","","","","5","","","","","","","","","","English","","","","","","","Place: FLAT-RM C 16F, KINGS WING PLAZA 1, NO 3 KWAN ST, SHATIN, HONG KONG 00000, PEOPLES R CHINA Publisher: AME PUBLISHING COMPANY Type: Article","","","","biomaterial; Bio-Oss (R) Collagen; case report; orthognathic; Orthognathic surgery; pseudoarthrosis treatment; vertical chin augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Effective regeneration of bone defects resulting from peri-implantitis is crucial to maintaining the functionality of dental implants. Purpose of the Study: The study aimed to compare the effectiveness of fine-particle dentin and Bio-Oss in the reconstruction of bone defects caused by peri-implantitis. Materials and Methods: The study included a comprehensive radiological assessment of changes in bone density over time. Bone density was assessed using Hounsfield Units (HUs) as a measure of bone attenuation, with radiological assessments performed at 8- and 12-week intervals during the healing process. The study included participants ranging in age from 30 to 65 years. Fifty-seven patients were divided into three groups: 22 patients received small-particle dentin, 15 received Bio-Oss, and 20 controls without bone substitute material. Results: The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine dentin group, 85% in the Bio-Oss group, and 70% in the control group. The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine-dentin group, 85% in the Bio-Oss group, and 70% in the control group. Conclusions: Both fine-particle dentin and Bio-Oss significantly improved bone density compared to the control group. Fine-particle dentin is suitable for immediate bone regeneration due to its rapid initial regeneration, while Bio-Oss provides long-term support, ideal for maintaining implant stability over a longer period of time. The results highlight the importance of selecting appropriate bone replacement materials depending on the clinical scenario to improve patient outcomes after dental implant placement.","2024-08","2025-04-25 16:49:30","2025-04-25 16:49:30","","","","16","13","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","Bio-Oss; bone regeneration; bone substitute materials; periimplantitis; small-particle dentin","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Method and Result: A 77-year-old woman with a non-healing anteromedial chest wound presented with sudden hypotension and hemoptysis. The computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of ascending aorta, with sternal erosion close to the wound. Conventional open repair was not preferred due to possible contamination of interposition graft and difficult sternum closure. The feasibility of endografting was confirmed based on appropriate landing zones. After endografts modification at back table, we made a left minithoracotomy and establish a through-and-through body floss wire from left ventricular apex to femoral artery. Retrograde delivery over this wire from femoral artery to ascending aorta and deployment of endografts under rapid ventricular pacing support were performed smoothly. Final angiography showed no endoleaks with patent coronary and arch vessels. Further wound debridement was done at the same time and wound culture yielded tuberculosis. After completing anti-tuberculosis therapy, no recurrent infection occurred. Postoperative 6-month CT scan disclosed optimal result. Conclusion: With adequate landing zones and delicate surgical strategy, endografting with anti-tuberculosis therapy may be an alternative treatment for ascending aortic tuberculosis pseudoaneurysm.","2017-11","2025-04-25 16:49:30","2025-04-25 16:49:30","","","","","45","","","","","","","","","","English","","","","","","","Place: 360 PARK AVE SOUTH, NEW YORK, NY 10010-1710 USA Publisher: ELSEVIER SCIENCE INC Type: Article","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community - eZ Publish we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm. In addition, the results of our study highlight the central importance of an integrative IT platform in boundary management activities. (C) 2014 Elsevier Ltd.

We conducted a large, multicenter, prospective, observational study to confirm the REGOMA data in a real-world setting. Patients and methods: The major inclusion criteria were histologically confirmed diagnosis of glioblastoma according to the World Health Organization (WHO) 2016 classification and relapse after radiotherapy with concurrent/adjuvant temozolomide treatment, good performance status [Eastern Cooperative Oncology Group performance status (ECOG PS 0-1)] and good liver function. Regorafenib was administered at the standard dose of 160 mg/day for 3 weeks on/1 week off. Brain magnetic resonance imaging was carried out within 14 days before starting regorafenib and every 8-12 weeks. The primary endpoint was overall survival (OS). The secondary endpoints were progression -free survival (PFS), objective response rate, disease control rate (DCR), safety and health-related quality of life. The Response Assessment in Neuro-Oncology (RANO) criteria were used for response evaluation and Common Terminology Criteria for Adverse Events (CTCAE) version 5 for assessment of adverse events (AEs). Results: From September 2020 to October 2022, 190 patients with recurrent glioblastoma were enrolled from 30 cancer centers in Italy: their median age was 58.5 years [interquartile range (IQR) 53-67 years], 68% were male and 85 (44.7%) were in optimal clinical condition (ECOG PS 0). The number of patients taking steroids at baseline was 113 (60%); the second surgery was carried out in 39 (20.5%). O6-methylguanine-DNA methyltransferase (MGMT) was methylated in 80 patients (50.3%) and 147 (92.4%) of the patients analyzed had isocitrate dehydrogenase (IDH) wild type. The median follow-up period was 20 months (IQR 15.6-25.5 months). The median OS was 7.9 months ([95% confidence interval (CI) 6.5-9.2 months] and the median PFS was 2.6 months (95% CI 2.3-2.9 months). Radiological response was partial response and stable disease in 13 (7.3%) and 26 (14.6%) patients, respectively, with a DCR of 21.9%. The median number of regorafenib cycles per patient was 3 (IQR 2.0-4.0). Grade 3-4 drug-related adverse events were reported in 22.6% of patients. A dose reduction due to AEs was required in 36% of patients. No deaths were considered as treatment-related AEs. Conclusions: This large, real -world observational study showed similar OS with better tolerability of regorafenib in patients with relapsed glioblastoma compared with the REGOMA study.","2024-04","2025-04-25 16:49:30","2025-04-25 16:49:30","","","","4","9","","","","","","","","","","English","","","","","","","Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER Type: Article","","","","glioblastoma; real-world; recurrent; REGOMA; regorafenib","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We aimed to compare the impact of early palliative care including formal concertation with oncologists on decision for an additional line of chemotherapy compared with usual oncology care. Methods This randomized prospective study enrolled adult women with metastatic breast cancer and visceral metastases with a 3rd- or 4th-line chemotherapy (CT). Patients received usual oncology care with a palliative care consultation only upon patient or oncologist request (standard group, S) or were referred to systematic palliative care consultation including a regular concertation between palliative care team and oncologists (early palliative care group, EPC). The primary endpoint was the rate of an additional CT (4th or 5th line) decision. Quality of life, symptoms, social support and satisfaction were self-evaluated at 6 and 12 months, at treatment discontinuation or 3 months after discontinuation. Results From January 2009 to November 2012, two authorized cancer centers included 98 women (EPC: 50; S: 48). Thirty-seven (77.1%, 95%CI 62.7-88%) patients in the EPC group had a subsequent chemotherapy prescribed and 36 (72.0%, 95%CI 57.5-83.8%) in the S group (p = 0.646). No differences in symptom control and global quality of life were observed, but less deterioration in physical functioning was reported in EPC (EPC: 0 [- 53-40]; S: - 6; 7 [- 60 to - 20]; p = 0.027). Information exchange and communication were significant improved in EPC (exchange, EPC: - 8.3 [- 30 to + 7]; S: 0.0 [- 17 to + 23]; p = 0.024; communication, EPC: 12.5 [- 8 to - 37]; S: 0.0 [- 21 to + 17]; p = 0.004). Conclusion EPC in metastatic breast cancer patients did not impact the prescription rate of additional chemotherapy in patients a 3rd- or 4th-line chemotherapy for metastatic breast cancer; however, EPC may contribute to alleviate deterioration in physical functioning, while facilitating communication.","2023-01","2025-04-25 16:49:31","2025-04-25 16:49:31","","","","1","31","","","","","","","","","","English","","","","","","","Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER Type: Article","","","","Advanced breast cancer; Chemotherapy; Early palliative care; Supportive care","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on the results of the ISG/OS-1 study, the MAP regimen (methotrexate [MTX], doxorubicin [ADM] and cisplatin [CDP] with the addition of ifosfamide [IFO] in poor-responder patients) was investigated in patients with nonmetastatic osteosarcoma of the extremity (ISG/OS-Oss study). Patients and methods. Compared with the ISG/OS-1 study (cumulative doses: ADM 420 mg/m(2), MTX 120 g/m(2), CDP 600 mg/m(2), IFO 30 g/m(2)), the ISG/OS-Oss study reduced the number of MTX cycles from 10 to 5 (cumulative MTX dose: 60 g/m(2)) in order to diminish treatment duration and toxicity. Results. From January 2007 to June 2011, 171 patients (median age 16 years, 60% males) were registered. The limb salvage rate was 94% and the good pathologic response rate 51% (these figures were 92% and 48%, respectively, in the ISG/OS-1 study). At a median follow-up of 39 months (range, 4-80), the 5-year overall survival rate was 80% (95% CI, 73%-87%) and the event-free survival was 50% (95% CI, 39%-59%). For comparison, the 5-year overall and event-free survival rates in ISG/OS-1 were 73% (95% CI, 65%-81%) and 64% (95% CI, 56%-73%), respectively. Conclusions. This study confirms that in nonmetastatic osteosarcoma of the extremity, conservative surgery in more than 90% and a good pathologic response rate of 50% can be expected with primary chemotherapy based on the MAP regimen. The response and resection rates in the ISG/OS-Oss study are in the same range as those of the previous study, whereas the event-free survival is lower than that previously achieved. Since the only difference between the two studies was the cumulative dose of postoperatively given MTX, our data support the importance of the cumulative dose of MTX in the MAP regimen.","2014-12","2025-04-25 16:49:31","2025-04-25 16:49:31","","612-619","","6","100","","","","","","","","","","English","","","","","","","Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD Type: Article","","","","methotrexate; neoadjuvant chemotherapy; osteosarcoma; tumor necrosis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Mean differences were expressed with the standard deviation and 95% confidence interval. The level of significance was 0.05. Survival of the suprastructures and implants was 100% with both treatment modalities. No significant difference in any of the outcome measures was observed between the test and control groups. High patient satisfaction and a significant improvement in quality of life were observed with both treatment modalities. Consequently, no significant difference in implant treatment outcome between the test and control groups was revealed after 1 year of implant loading.

Anorganic bovine bone (Bio-Oss) has been reported to be osteoconductive, and no inflammatory responses have been observed with the use of this biomaterial. One of the main questions pertaining to Bio-Oss concerns its biodegradation and substitution by host bone. Some investigators have observed rapid replacement by host bone, while other researchers observed slow resorptive activity or no resorption at all. The aim of the present study was to conduct a long-term histologic analysis of retrieved specimens in humans where Bio-Oss was used in sinus augmentation procedures. Specimens were retrieved from 20 patients after varying peri ods from 6 months to 4 years and were processed to obtain thin ground sections. Bio-Oss particles were surrounded for the most part by mature, compact bone. In some Haversian canals it was possible to observe small capillaries, mesenchymal cells, and osteoblasts in conjunction with new bone. No gaps were present at the interface between the Bio-Oss particles and newly formed bone, in specimens retrieved after 18 months and 4 years, it was also possible to observe the presence of osteoclasts in the process of resorbing the Bio-Oss particles and neighboring newly formed bone. Bio-Oss appears to be highly biocompatible and osteoconductive, is slowly resorbed in humans, and can be used with success as a bone substitute in maxillary sinus augmentation procedures.","1999-12","2025-04-25 16:49:31","2025-04-25 16:49:31","","835-840","","6","14","","","","","","","","","","English","","","","","","","Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC Type: Article","","","","anorganic bovine bone; biomaterials; sinus augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

BMSCs obtained from rabbits were transfected with bFGF gene-encoding plasmids and proliferation rate and the differentiation marker alkaline phosphatase activity were measured. Following seeding into Bio-Oss collagen and 9-day culture in vitro, the surface morphology of the Bio-Oss was assessed using scanning electron microscopy analysis. Three mandibular defects were induced in the lower border of the bilateral mandibular ramus in each New Zealand white rabbit (total n=6). Three scaffolds, group A (seeded with BMSCs/bFGF), B (seeded with BMSCs/pVAX1) and C (cell-free), which had been cultured in vitro under standard cell culture conditions for 18 days, were implanted into mandibular defects under sterile conditions. Animals were sacrificed by anesthesia overdose 12 weeks following surgery and the scaffolds were extracted for bone mineral density and histological analyses. Results indicate that bFGF was successfully transfected into BMSCs. Proliferation and osteoblast differentiation of BMSCs were stimulated by bFGE: in vitro. No differences were identified in surface morphology for Bio-Oss loaded with variable groups of cells. At week 12 following implantation of Bio-Oss scaffolds, mineralization of BMSCs in Bio-Oss scaffolds was observed to be increased by bFGF. New bone and cartilage formation was revealed in hematoxylin and eosin-stained sections in Bio-Oss scaffolds and was most abundant in group A (BMSCs transfected with bFGF). In the current study, the bFGF gene was transfected into BMSCs and expressed successfully. bFGF promoted proliferation and differentiation of BMSCs in vitro and implantation of bFGF-expressing BMSCs combined with Bio-Oss enhanced new bone regeneration more effectively than traditional methods.","2013-01","2025-04-25 16:49:31","2025-04-25 16:49:31","","99-104","","1","7","","","","","","","","","","English","","","","","","","Place: POB 18179, ATHENS, 116 10, GREECE Publisher: SPANDIDOS PUBL LTD Type: Article","","","","Bio-Oss; basic fibroblast growth factor; bone marrow stromal cells; mandibular defect","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This involved a total of 15 sinus floor elevation procedures being carried out on 11 patients (average age of 49.6 years) according to the technique described by Tatum (1986). The subantral sinus cavity was augmented using bovine apatite combined with venous blood. After an average healing phase of 6.8 months, trephine burrs were used to take 22 bone biopsies from the augmented sinus region. Then 38 Branemark(R) implants were inserted in both the osteotomies resulting from bone sampling and in regular sites in the augmented posterior maxilla. Histomorphometric analysis of ground sections from the bone biopsies prepared according to the standard method of Donath & Breuner (1982) produced an average percentage of newly-formed bone of 14.7% (+/-5.0%) and a proportion of residual xenogenic bone substitute material of 29.7% (+/-7.8%). Some 29.1% (+/-8.1%) of the surface of the Bio-Oss(R) granulate was in direct contact with newly-formed bone. Histologically, newly-developed bone became evident, partly invaginating the particles of apatite and forming bridges in the form of trabeculae between the individual Bio-Oss(R) particles. Despite the absence of osteoclastic activity, the inward growth of bone indicates slow resorption of the xenogenic bone graft material. When the implants were uncovered, after an average healing phase of 6 months, 4 of the 38 implants had become loose. Of these 4 implants, 1 had to be subsequently explanted, while the others remained as “sleeping implants” and were not included in the implants superstructure.

Methods Medical records of Department of Oral and Maxillofacial Surgery of Shandong Provincial Hospital were screened for patients who had been treated with immediate implant implantation in the esthetic area using either MC (Allgens (R), Beijing Allgens Medical Science and Technology Co., Ltd., China) or Bio-Oss (Bio-Oss (R), Geistlich Biomaterials, Wolhusen, Switzerland), between January 2018 and December 2019. All patients fulfilling the in-/exclusion criteria and following followed for a minimum period of 1 year after surgery were enrolled into the presented study. Implant survival rate, radiographic, esthetic and patient satisfactory evaluations were performed. Results Altogether, 70 patients were included in the study; a total of 80 implants were inserted. All implants had good initial stability. The survival rate of implants was 100% at 1-year follow-up. The differences in horizontal and vertical bone loss between the MC group (0.72 +/- 0.26 mm, 1.62 +/- 0.84 mm) and the Bio-Oss group (0.70 +/- 0.52 mm, 1.57 +/- 0.88 mm) were no significant difference statistically no significant 6 months after permanent restoration. Similar results occurred at 12 months after permanent restoration functional loaded. Clinical acceptability defined by pink esthetic score (PES) >= 6 (6.07 +/- 1.62 vs. 6.13 +/- 1.41) was not significantly different between groups. Patient satisfaction estimated by visual analog scale (VAS) was similar (8.56 +/- 1.12 vs. 8.27 +/- 1.44), and the difference was no significant difference between the two groups. Conclusions The biomimetic MC showed a similar behaviour as Bio-Oss not only in its dimensional tissues changes but also in clinical acceptability and patient satisfaction. Within the limitations of this study, these cases show that MC could be considered as an alternative bone graft in IIP","2021-08-10","2025-04-25 16:49:31","2025-04-25 16:49:31","","","","1","21","","","","","","","","","","English","","","","","","","Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC Type: Article","","","","Immediate implant implantation; Mineralized collagen; Osseointegration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To assess this issue, this paper describes a real-time root cause analysis mechanism, which can pinpoint an accurate root cause and identify the influence on services. We investigated an interworking mechanism; based on a web service interface between an inventory and fault management systems and developed prototypes of them as part of an operation support system (OSS), which is capable of managing not only a core network and a metro ring network, but also a customer network. By introducing a hierarchical circuit model in the inventory management system and the proposed scanning algorithm over multiple layers and domains implemented in the fault management system, our developed root cause analysis was successfully verified using the testbed network environment; indicating relatively fast and scalable operation.","2009","2025-04-25 16:49:31","2025-04-25 16:49:31","","141-144","","","","","","","","","","","IEEE","345 E 47TH ST, NEW YORK, NY 10017 USA","English","","","","","","","Backup Publisher: IFIP; IEEE Type: Proceedings Paper","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Long-term follow-up of implants placed in BCP after sinus augmentation is still missing. Purpose: The primary aim of the study was to compare survival rates and marginal bone loss of Straumann SLActive implants placed in either BCP (test) or Bio-Oss (R) (DBB) (control) after sinus floor augmentation. The secondary aim was to calculate graft sinus height at different time points. Materials and Methods: Bilateral sinus floor augmentation was performed in a split mouth model. Eleven patients (mean age 67 years) received 100% BCP on one side and 100% DBB on the contralateral side. After 8 months of graft healing, 62 Straumann SLActive implants were placed. After 5 years of functional loading (6 years after augmentation) of implants, marginal bone levels and grafted sinus height were measured, and implant survival and success rates were calculated. Results: After 5 years of loading, all prosthetic constructions were in function although two implants were lost in each grafting material. The overall implant survival rate was 93.5% (91.7% for BCP, 91.3% for DBB, and 100% for residual bone). The success rates were 83.3% and 91.3% for BCP and DBB, respectively. There was no statistically significant difference in mean marginal bone level after 5 years between BCP (1.4 +/- 1.2 mm) and DBB (1.0 +/- 0.7 mm). Graft height reduction (GHR) after 6 years was limited to 6.6% for BCP and 5.8% for DBB. Conclusion: In this limited RCT study, the choice of biomaterial used for sinus floor augmentation did not seem to have any impact on survival rates and marginal bone level of the placed implants after 5 years of functional loading and GHR was minimal.","2016-10","2025-04-25 16:49:31","2025-04-25 16:49:31","","926-936","","5","18","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","biphasic calcium phosphate; bone substitutes; deproteinized bovine bone; sinus floor augmentation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we evaluated biopsies of grafted bone with a mixture of autologous bone and Bio-Oss((R)) or BoneCeramic((R)) after two different healing time periods to understand the molecular process underlying bone formation after MSFE. Material and methodsSeven patients, following a bilateral split-mouth design model and needing a MSFE to allow implant placement, were recruited for this study. Right or left sinuses were grafted with autologous maxillary bone combined either with Bio-Oss((R)) or BoneCeramic((R)), respectively. Twenty biopsies were taken at the time of implant insertion after 4-5months or 6-8months of MSFE, and analyzed by micro-computed tomography (microCT) and gene-expression analysis. ResultsMicroCT analysis revealed no differences in the morphometric parameters or BMD either after 4-5months or 6-8months of MSFE between Bio-Oss((R)) and BoneCeramic((R)). At molecular level, a higher expression of bone forming gene Runx2 was observed after 4-5months of MSFE in the Bio-Oss((R)) compared with the BoneCeramic((R)) group. ConclusionsOur results indicate that differences found at the molecular level between Bio-Oss((R)) and BoneCeramic((R)) are not translated to important differences in the 3D microstructure and BMD of the grafted bone.","2015-06","2025-04-25 16:49:31","2025-04-25 16:49:31","","727-735","","6","26","","","","","","","","","","English","","","","","","","Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY Type: Article","","","","bone graft; clinical study; dental implant; gene expression; maxillary sinus floor elevation (MSFE); micro-computed tomography (microCT)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, patient's perception of recovery and satisfaction with the surgical intervention are rarely reported. The objective of the present randomized controlled trial was to assess patient's perception of recovery after osteotome-mediated sinus floor elevation with Bio-Oss collagen compared with no grafting material. Forty healthy patients were randomly allocated to Bio-Oss collagen or no grafting material. Oral health-related quality of life was assessed by Oral Health Impact Profile-14 at enrollment. Patient's perception of recovery was assessed by self-administrated questionnaires and visual analog scale evaluating pain, social and working isolation, physical appearance, duration and quality of life alterations, eating and speaking ability, diet variations, and sleep impairment after 1 week and 1 month, respectively. Descriptive statistics was expressed as mean percentage with standard deviation. Correlation between impaired oral health-related quality of life, age, gender, and recovery were assessed by T test. Level of significance was 0.05. Results Osteotome-mediated sinus floor elevation is associated with high patient satisfaction, limited postoperative discomfort, and willingness to undergo similar surgery. Influence on patient's daily life activities seems to be minimal and limited to the first postoperative days. Most patients managed to return to work and their routine daily activities after 0-2 days. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery. However, number of days with pain, eating difficulties, and sleep disturbances were significantly increased with Bio-Oss collagen compared with no grafting material (P<0.05).

Forty healthy patients who met the necessary eligibility criteria were allocated by block randomization to either the test group (20 patients) or control group (20 patients). Cone beam computed tomography scans were obtained at enrolment (T0), immediately after surgery (T1), at delivery of the prosthetic rehabilitation (T2), and 1 year after functional implant loading (T3).

The LIG sensors are fabricated on polyimide (PI) Flexible Printed Circuit Board (FPCB) through CO2 infrared laser direct-write method. The LIG sensors provide repeatable high-precision temperature sensing, humidity measurement, and strain detection capability. The temperature sensing characterization shows the resistive LIG sensor has a sensitivity of -0.0493 %/degrees C, the linear fit R-square factors = 0.9973 across -40 degrees C to 125 degrees C. The capacitive humidity sensor achieves a normalized response of 2260% at 95% relative humidity (RH). Our proposed AFE chip contains a hybrid folded-cascode Operational Amplifier (OPAMP) with 92 dB gain and 12.5 MHz Gain Bandwidth Product (GBW), and a 14-bit 10 MHz Successive Approximation Register Analog-to-Digital Converter (SAR ADC). Designed using open-source analog flow and fabricated in GF180 OpenPDK, the AFE chip serves as a flexible and universal readout platform, adaptable for various sensing applications. A real-time demonstration of finger bending detection, with readings output by the AFE Chip, is performed to validate the system functionalities and robustness. The temperature, humidity, strain sensing capability provide by the wearable system are attractive for personal healthcare application.

We retrospectively collected data on advanced NSCLC not receiving a first-line platinum combination, focusing on clinical selection criteria. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor performance status. A single agent chemotherapy was offered with the prevalence of oral metronomic vinorelbine. In the whole population, progression-free survival and overall survival ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. Limited evidence is available concerning the selection criteria and the outcomes of platinum unfit newly diagnosed advanced NSCLC patients receiving single-agent chemotherapy. We retrospectively collected data on consecutive, stage IIIB-IV, EGFR/ALK negative and PD-L1 < 50% NSCLC patients treated with first-line single agent chemotherapy. Baseline characteristics, outcome measures and toxicities were recorded, as well as criteria according to which treatment selection was made and what percentage of patients did not receive a first-line platinum-based chemotherapy. Two-hundred and twenty-one patients were included. Median age was 79 (range 56-92) years, M/F 165(74.6%)/56(25.4%), ECOG performance status (PS) 0/1/ >= 2 23(10.9%)/94(42.5%)/103(46.6%), with a median of two serious comorbidities. A median of 25% (range 10%-30%) of newly diagnosed NSCLC did not receive a first-line platinum combination. Clinical criteria according to which decision was made were older age (76.5%), comorbidities (72%), poor PS (55.2%) and familiar or social issues (10%). Single-agent treatment consisted of oral metronomic vinorelbine (MetV 78.6%), gemcitabine (Gem 10%), oral standard vinorelbine (Vin 8.2%) and other (O 3.2%). Median progression-free survival (PFS) and overall survival (OS) of single agent treatments ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. All grade toxicities did not differ among single agents, while grade 3-4 toxicities were less frequent with MetV. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor PS. An oral treatment was frequently proposed with MetV being the most frequent choice according to its safety profile.","2022-12","2025-04-25 16:49:32","2025-04-25 16:49:32","","","","24","14","","","","","","","","","","English","","","","","","","Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI Type: Article","","","","elderly; low performance status; metronomic; non-small cell lung cancer; single agent chemotherapy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, controversy exists regarding the need to cover the lateral osteotomy site with a membrane. Also, the healing period before loading remains undefined when machined-surface implants are placed. Twenty-nine patients showing reduced bone volume in the posterior maxilla had 61 Branemark System implants placed in 30 sinuses augmented with a lateral osteotomy approach. Sinuses grafted with Bio-Oss and covered with a collagen membrane Bio-Gide (M+) received 29 implants, while grafted but uncovered sites (M-) received 32 implants. An immediate procedure was followed to place 41 implants and a staged procedure was used for 20 implants, Abutment connection was made in 2 distinct postoperative periods: 6 to 9 months and over 9 months. The patients were followed for an average of 22.4 months. The survival rate of the implants was dependent on the postoperative healing time and membrane presence. In case of the immediate procedure and in M- sites, when residual bone height was less than 5 mm, more failures occurred when the loading was done at 6 to 9 months than after 9 months. No failures occurred in the M- series when a staged approach was followed. The overall survival rate was 78.1% for the M- sites and 93.1% for the M+ sites. No failures occurred (0/35) in the control implants placed in adjacent native bone. Implant survival rate was related to the quality of the reconstructed cortical plate and to implant length. The concomitant use of a collagen barrier to cover the osteotomy site, when machined-surface implants were used in sinus grafting, seemed to improve the quality of the graft healing and survival rate of the implants loaded between 6 and 9 months after placement.","2001-10","2025-04-25 16:49:32","2025-04-25 16:49:32","","713-721","","5","16","","","","","","","","","","English","","","","","","","Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC Type: Article","","","","bone grafting; endosseous dental implants; maxillary sinus; membranes","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study investigated mechanical strength in support of histological findings, specifically for tissue-engineered bone with mesenchymal stem cells (MSCs) and platelet-rich-plasma (PRP). Initially, teeth were extracted, and bone defects on both sides of the mandible were prepared with a trephine bar. The defects were implanted by using the following graft materials: 1) PRP, 2) PRP and dog MSCs (dMSCs), 3) autogenous bone (PCBM), 4) bone substitute (Bio-Oss (R)), and 5) control (defects only). After 2, 4, 8, and 12 weeks of implantation, the defects were histologically assessed to examine their mechanical properties. According to histological observations, the dMSCs/PRP groups had well-formed mature bone compared with the control (defects only), Bio-Oss (R), and PRP groups. The Vickers hardness test values were 8 (control), 9 (PRP), not detected (Bio-Oss (R)), 11 (PCBM), and 17 (dMSCs/PRP) after 2 weeks. Therefore, tissue-engineered bone can be used for early stage bone regeneration from the viewpoint of histology and mechanical properties.

Owing to the unrestricted access to source code, version control information, and bug tracking database, a comprehensive study on the Development Process associated with an OSS project is feasible. In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.","2025-03","2025-04-25 16:50:18","2025-04-25 16:50:18","","4","","1","33","","","","","","","","","","English","","","ABI/INFORM Global","3145911815","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Quality+enhancement+in+OSS+development+process%3A+a+quantitative+framework+approach&rft.au=.&rft.aulast=&rft.aufirst=&rft.date=2025-03-01&rft.volume=33&rft.issue=1&rft.spage=4&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-024-09705-0","Open source software; GitHub; Software quality; Resource allocation; Computers--Software; Source code; Decision analysis; Comparative analysis; Quality assessment; Operations research; Quantitative analysis; Multiple criteria decision making; Development process; Multi-criteria decision analysis; Multiple criterion; Project feasibility; Version control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 16:50:19","2025-04-25 16:50:19","","1449-1469","","4","63","","","","","","","","","","English","","","ABI/INFORM Global","3129871390","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Small+Business+Economics&rft.atitle=Financing+A+Free-for-All%3A+Crowdfunding+Open-Source+Software&rft.au=Bort%2C+James%3BMeoli%2C+Azzurra%3BSullivan%2C+David+W..&rft.aulast=Bort&rft.aufirst=James&rft.date=2024-12-01&rft.volume=63&rft.issue=4&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Small+Business+Economics&rft.issn=0921898X&rft_id=info:doi/10.1007%2Fs11187-023-00867-y","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business And Economics--Small Business; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A qualitative multi-case study of three ecosystems was conducted, with data collected through interviews, participant observation, and analysis of online discussion forums. The study presents a model for health-sustaining activities in public-sector FOSS ecosystems. Orchestrators and keystone players are found to engage in health-sustaining activities through rulemaking, role creation, and tool provision, hinting at the explanatory potential of Activity Theory.

In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace.

Collectively, these interests enable the project's long-term development.","2023","2025-04-25 16:50:19","2025-04-25 16:50:19","","3048-3078","","7","36","","","","","","","","","","English","","","ABI/INFORM Global","2919795922","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/yExBX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=LncIr61gIxgDAl6C3qBSegac3ZU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=How+do+different+stakeholder+groups+within+an+open+source+software+project+influence+the+project%27s+development%3A+a+case+study+of+OpenSimulator&rft.au=Paul+Di+Gangi%3BTeigland%2C+Robin%3BYetis%2C+Zeynep.&rft.aulast=Paul+Di+Gangi&rft.aufirst=&rft.date=2023-10-01&rft.volume=36&rft.issue=7&rft.spage=3048&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-10-2021-0751","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Research; Success; Text analysis; Strategy; Case studies; Virtual community; Stakeholders; Software testing; Case study; Public domain; Investigations; Software project management; Entrepreneurs; Value creation; Value proposition; Library And Information Sciences--Computer Applications; Small & medium sized enterprises-SME; Academic staff; FLOSS (Open source software); Formal organization; Mailing lists; OpenSimulator; Stakeholder theory; Time use; Virtual world","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-25 16:50:19","2025-04-25 16:50:19","","361","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","2783221355","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Resilience+in+the+Open+Source+Software+Community%3A+How+Pandemic+and+Unemployment+Shocks+Influence+Contributions+to+Others%27+and+One%27s+Own+Projects&rft.au=Malgonde%2C+Onkar+S%3BSaldanha%2C+Terence+J+V%3BMithas%2C+Sunil.&rft.aulast=Malgonde&rft.aufirst=Onkar&rft.date=2023-03-01&rft.volume=47&rft.issue=1&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2022%2F17256","Open source software; COVID-19; Computers; Resilience; Pandemics; Public health; Community; Open source; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Nature conservation; Resource conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks.Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.Originality/value This study is the first attempt to consider the network metrics in both module networks of the technical sub-system and developer networks of the social sub-system to better understand their influences on project success.","2023","2025-04-25 16:50:19","2025-04-25 16:50:19","","895-915","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","2787783369","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/HROxQ?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=sbxTkpzdpsjcWmCM2xTauq2KWz4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=Social-technical+network+effects+in+open+source+software+communities%3A+understanding+the+impacts+of%26nbsp%3Bdependency+networks+on%26nbsp%3Bproject+success&rft.au=Wu%2C+Jiang%3BHuang%2C+Xiao%3BWang%2C+Bin.&rft.aulast=Wu&rft.aufirst=Jiang&rft.date=2023-02-15&rft.volume=36&rft.issue=2&rft.spage=895&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-09-2021-0684","Design; Open source software; Social network analysis; Information technology; Collaboration; Open source; Software engineering; Software; Computer architecture; Software reliability; Research; Success; Teams; Social networks; Software development; Software quality; Public domain; Investigations; Project Success; Network effect; Social network; Library And Information Sciences--Computer Applications; Dependency; Closeness; Dependency network; Dependency networks; Modules; Open source software community; Social-technical system","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023","2025-04-25 16:50:20","2025-04-25 16:50:20","","3106-3130","","5","49","","","","","","","","","","English","","","ABI/INFORM Global","2814541650","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Understanding+Mentors%26rsquo%3B+Engagement+in+OSS+Communities+via+Google+Summer+of+Code&rft.au=Tan%2C+Xin%3BZhou%2C+Minghui%3BZhang%2C+Li.&rft.aulast=Tan&rft.aufirst=Xin&rft.date=2023-01-01&rft.volume=49&rft.issue=5&rft.spage=3106&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2023.3242415","Open source software; Organizations; Mentors; Motivation; Data analysis; Students; Open-source software; Task analysis; Strategy; Mentoring; Sustainability; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; Computers--Software; taxonomy; Challenge; mentoring process; Mentorship; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers’ early careers and hence shed light on future research in this direction.","2023","2025-04-25 16:50:20","2025-04-25 16:50:20","","529-548","","2","49","","","","","","","","","","English","","","ABI/INFORM Global","2776777604","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Off+to+a+Good+Start%3A+Dynamic+Contribution+Patterns+and+Technical+Success+in+an+OSS+Newcomer%26rsquo%3Bs+Early+Career&rft.au=Yang%2C+Yue%3BWang%2C+Yi%3BRedmiles%2C+David.&rft.aulast=Yang&rft.aufirst=Yue&rft.date=2023-01-01&rft.volume=49&rft.issue=2&rft.spage=529&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2022.3156071","Careers; open source; Task analysis; Ecosystems; Success; Documentation; Engineering profession; Codes; Correlation; Newcomer; Focusing; Statistical analysis; Computers--Software; Empirical analysis; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader.

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time.

However, the differential impacts of such social influence on developers' initial and sustained participation behaviors were largely overlooked in previous research. We empirically studied the impacts of two social influence mechanisms—word‐of‐mouth (WOM) and observational learning (OL)—on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.","2021-09","2025-04-25 16:50:20","2025-04-25 16:50:20","","1133-1147","","9","72","","","","","","","","","","English","","","ABI/INFORM Global","2558095618","","","Place: Hoboken Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Science+and+Technology&rft.atitle=Differential+impacts+of+social+influence+on+initial+and+sustained+participation+in+open+source+software+projects&rft.au=Yang%2C+Xuan%3BLi%2C+Xiao%3BHu%2C+Daning%3BWang%2C+Harry+Jiannan.&rft.aulast=Yang&rft.aufirst=Xuan&rft.date=2021-09-01&rft.volume=72&rft.issue=9&rft.spage=1133&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Science+and+Technology&rft.issn=23301635&rft_id=info:doi/10.1002%2Fasi.24481","Open source software; Learning; Platforms; Library And Information Sciences; Social research; Open source; Software; Open-source software; Social influence; Social Influences; Social networks; Software development; Public domain; Software Projects; Software development tools; Modeling (Psychology); Observational Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 16:50:20","2025-04-25 16:50:20","","8","","","49","","","","","","","","","","English","","","ABI/INFORM Global","2582094786","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/x0MyK?_a=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&_s=%2FlTTM3bDFac2N1veyo77qKjQ6No%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Episodic+Peripheral+Contributors+and+Technical+Dependencies+in+Open+Source+Software+%28OSS%29+Ecosystems&rft.au=Moon%2C+Eunyoung.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2021-01-01&rft.volume=49&rft.issue=&rft.spage=8&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04908","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Ownership, security, quality concerns, or support confidence are widely common reasons. Furthermore, these concerns are intensified when the OSS is to take part in critical sections of the evolved system.

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been institutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous security in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed security controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption enables businesses to deliver time-to-market security ready applications and services with accelerated velocity and sustainable agility in a cost-effective way.","2020-10","2025-04-25 16:50:20","2025-04-25 16:50:20","","1-28","","","97","","","","","","","","","","English","","","ABI/INFORM Global","2454359046","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Computers+%26+Security&rft.atitle=Modeling+continuous+security%3A+A+conceptual+model+for+automated+DevSecOps+using+open-source+software+over+cloud+%28ADOC%29&rft.au=Kumar%2C+Rakesh%3BGoyal%2C+Rinkaj.&rft.aulast=Kumar&rft.aufirst=Rakesh&rft.date=2020-10-01&rft.volume=97&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Computers+%26+Security&rft.issn=01674048&rft_id=info:doi/10.1016%2Fj.cose.2020.101967","Open source software; Cloud computing; Automation; Security; Business; Cybersecurity; Software development; Assurance; Public domain; Economic; Computers--Electronic Data Processing; Codification; Workflow; Applications programs; Business process; DevOps; Performance measurement; Security controls","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 16:50:20","2025-04-25 16:50:20","","1439","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2447305472","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Takeoff+of+Open+Source+Software%3A+A+Signaling+Perspective+Based+on+Community+Activities&rft.au=Setia%2C+Pankaj%3BBayus%2C+Barry+L%3BRajagopalan%2C+Balaji.&rft.aulast=Setia&rft.aufirst=Pankaj&rft.date=2020-09-01&rft.volume=44&rft.issue=3&rft.spage=1439&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F12576","Open source software; Computers; Open source; Software; Open-source software; Signaling; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for‐profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 16:50:21","2025-04-25 16:50:21","","369-402","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2352536913","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+Third+Design+Space%3A+A+postcolonial+perspective+on+corporate+engagement+with+open+source+software+communities&rft.au=Kendall%2C+Kenneth+E%3BKendall%2C+Julie+E%3BGermonprez%2C+Matt%3BMathiassen%2C+Lars.&rft.aulast=Kendall&rft.aufirst=Kenneth&rft.date=2020-03-01&rft.volume=30&rft.issue=2&rft.spage=369&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12270","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Computers--Computer Systems; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 16:50:21","2025-04-25 16:50:21","","20","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2500501225","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/JGBVI?_a=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&_s=ZwMsI0CRPDfS%2Fx12%2Fam7rwPvXL8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Decision-making+Processes+in+Community-based+Free%2FLibre+Open+Source+Software-development+Teams+with+Internal+Governance%3A+An+Extension+to+Decision-making+Theory&rft.au=Eseryel%2C+U+Yeliz%3BKangning+Wei%3BCrowston%2C+Kevin.&rft.aulast=Eseryel&rft.aufirst=U&rft.date=2020-01-01&rft.volume=46&rft.issue=&rft.spage=20&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04620","Open source software; Decision making; Computers--Information Science And Information Theory; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While about half of respondents confirmed using OSS, the authors found surprisingly low levels of intent to adopt from current non-adopters.Practical implicationsThis research offers insights for promoting OSS adoption. Also, it provides funding agencies and administrators with guidelines to encourage successful deployment of OSS in higher education.Originality/valueWhile extant research is mostly anecdotal, this research draws from an online survey to snap-shot the current state of OSS adoption in US academic libraries and provides a baseline for practice and research.","2019","2025-04-25 16:50:21","2025-04-25 16:50:21","","641-659","","4","37","","","","","","","","","","English","","","ABI/INFORM Global","2308435090","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/DsyOJ?_a=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&_s=uVzfcu7K0PQpsfHIgCgr2uOWIGc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+context+and+state+of+open+source+software+adoption+in+US+academic+libraries&rft.au=Choi%2C+Namjoo%3BPruett%2C+Joseph+A.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2019-10-01&rft.volume=37&rft.issue=4&rft.spage=641&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2FLHT-02-2019-0042","Open source software; Higher education; Data analysis; Open source; Software; Libraries; Open-source software; Usability; Research; Case studies; Technology adoption; Software quality; Public domain; Proprietary; United States--US; Cost control; Developing countries--LDCs; Library And Information Sciences--Computer Applications; 51921:Libraries and Archives; Barrier; Academic libraries; Institutional repositories; Library; Integrated library systems-ILS; Internet resources; Survey; Academic library; Driver; Electronic resources management; Information technology adoption; University libraries; USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 16:50:21","2025-04-25 16:50:21","","764","","3","30","","","","","","","","","","English","","","ABI/INFORM Global","2307721543","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Does+Superposition+Influence+the+Success+of+FLOSS+Projects%3F+An+Examination+of+Open-Source+Software+Development+by+Organizations+and+Individuals&rft.au=Medappa%2C+Poonacha+K%3BSrivastava%2C+Shirish+C.&rft.aulast=Medappa&rft.aufirst=Poonacha&rft.date=2019-09-01&rft.volume=30&rft.issue=3&rft.spage=764&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2018.0829","Open source software; Organizations; Motivation; Open source; Software engineering; Open-source software; Computer architecture; Ownership; Success; Computers--Information Science And Information Theory; Project management; Software development; Freeware; 51821:Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services; Modular design; Project Success; Superposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, a modified non-homogeneous Poisson process model is developed in an imperfect debugging environment by assuming that new faults may be introduced in fault detection and correction process. Then, the detection rate and remaining faults of previous release are considered in the modeling and analysis of reliability of the current release. The optimal version-update time is computed using multi-attribute utility theory for these software systems, considering the two main utility factors, namely, rapid release strategy and level of reliability. The proposed models are verified on real data sets and are compared with other existing models. The proposed decision models may be helpful for the software developing management to decide the optimal version update time for open source software.","2019-01","2025-04-25 16:50:21","2025-04-25 16:50:21","","31-38","","1","41","","","","","","","","","","English","","","ABI/INFORM Global","2544345120","","","Place: Calgary Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Computers+%26+Applications&rft.atitle=Reliability+analysis+of+open+source+software+systems+considering+the+effect+of+previously+released+version&rft.au=Pachauri%2C+Bhoopendra%3BKumar%2C+Ajay%3BDhar%2C+Joydip.&rft.aulast=Pachauri&rft.aufirst=Bhoopendra&rft.date=2019-01-01&rft.volume=41&rft.issue=1&rft.spage=31&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Computers+%26+Applications&rft.issn=1206212X&rft_id=info:doi/10.1080%2F1206212X.2018.1497575","Open source software; Open source; open source software; Software; Open-source software; Fault detection; Public domain; Software upgrading; Software system; Debugging; Reliability analysis; Computers--Machine Theory; imperfect debugging; multi-attribute utility theory; multiple-release; Reliability aspects; Software reliability growth model; Utility theory","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Only a few empirical studies investigate how the choice of components is conducted in industrial practice. This is important to understand to tailor research solutions to the needs of the industry. Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better. Interestingly, the final decision was perceived negatively in nine cases and positively in seven cases, while in the remaining cases it was perceived as neither positive nor negative.","2018","2025-04-25 16:50:21","2025-04-25 16:50:21","","237-261","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2174495958","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Choosing+Component+Origins+for+Software+Intensive+Systems%3A+In-House%2C+COTS%2C+OSS+or+Outsourcing%3F%26mdash%3BA+Case+Survey&rft.au=Petersen%2C+Kai%3BBadampudi%2C+Deepika%3BSyed+Muhammad+Ali+Shah%3BWnuk%2C+Krzysztof%3BGorschek%2C+Tony%3BPapatheocharous%2C+Efi%3BAxelsson%2C+Jakob%3BSentilles%2C+Severine%3BCrnkovic%2C+Ivica%3BCicchetti%2C+Antonio.&rft.aulast=Petersen&rft.aufirst=Kai&rft.date=2018-01-01&rft.volume=44&rft.issue=3&rft.spage=237&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2017.2677909","Decision making; Outsourcing; OSS; Software; Computer architecture; outsourcing; Companies; Industries; Computers--Software; Component-based software engineering; COTS; in-house","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS. Cependant, ces recherches se sontprincipalement concentrées sur des projets reconnus et de grande envergure, tels que Linux ou Apache. Une investigation des projets moins connus permettrait une compréhension plus complete et d'éviter un taux d'échec important des projets OSS. Cette étude investigue donc la combi- naison de trois facteurs : les interactions des utilisateurs et développeurs, la pénétration du marché et le stade de développement, afin d'observer leur impact sur la popularité des projets OSSpeu connus. Nous a vons pour cela développé un modele empirique de la popularité des OSS, et avons testé nos hypotheses sur 657projets de logiciel libre. Les résultats de cette recherche montrent que la combinaison des trois facteurs a un impact positif sur la popularité des OSS. De plus, contrairement aux études précédentes, nos résultats révelent également que les interactions entre utilisateurs et développeurs ont un rôle plus important que les activités reliées á la résolution de bugs dans la réussite des projets. Cette recherche propose une nouvelle maniere de mesurer la popularité d'un projet OSS et offrant ainsi aux organisations une meilleure compréhension.","2017-10","2025-04-25 16:50:21","2025-04-25 16:50:21","","47-74,117","","3","22","","","","","","","","","","English","","","ABI/INFORM Global","1969517670","","","Place: Paris Publisher: Editions ESKA","","; ","https://media.proquest.com/media/hms/PFT/1/g3eZ3?_a=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&_s=TDPmpbTuX3nLSv9pl2dBP8w0%2F4M%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Syst%C3%A8mes+d%27Information+et+Management&rft.atitle=OSS+popularity%3A+Understanding+the+relationship+between+user-developer+interaction%2C+market+potential+and+development+stage&rft.au=Cheruy%2C+Cl%C3%A9mence%3BRobert%2C+Frank%3BBelbaly%2C+Nassim.&rft.aulast=Cheruy&rft.aufirst=Cl%C3%A9mence&rft.date=2017-10-01&rft.volume=22&rft.issue=3&rft.spage=47&rft.isbn=&rft.btitle=&rft.title=Syst%C3%A8mes+d%27Information+et+Management&rft.issn=12604984&rft_id=info:doi/","Open source software; Information systems; Business And Economics--Management; Hypotheses; Open-source software; Linux; Success; Social; Social networks; Software quality; Public domain; Freeware; Business metrics; Developer; Investigations; Management science; Market penetration; Market potential; Popularity; User services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume – suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017","2025-04-25 16:50:21","2025-04-25 16:50:21","","43-66","","2","29","","","","","","","","","","English","","","ABI/INFORM Global","2866855510","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/wC7YX?_a=ChgyMDI1MDQwODE3MTAxNjg4ODo5MzA4NjESBTk5OTQxGgpPTkVfU0VBUkNIIg4xNjUuMTI0Ljg1LjEyOSoFMjkyNDEyCjI4NjY4NTU1MTA6DURvY3VtZW50SW1hZ2VCATBSBk9ubGluZVoCRlRiA1BGVGoKMjAxNy8wNC8wMXIKMjAxNy8wNi8zMHoAggElUC0xMDAwMDAxLTEyODYxLUNVU1RPTUVSLW51bGwtMTE0NDQwMpIBBk9ubGluZcoBVE1vemlsbGEvNS4wIChNYWNpbnRvc2g7IEludGVsIE1hYyBPUyBYIDEwLjE1OyBydjoxMzcuMCkgR2Vja28vMjAxMDAxMDEgRmlyZWZveC8xMzcuMNIBElNjaG9sYXJseSBKb3VybmFsc5oCB1ByZVBhaWSqAitPUzpFTVMtTWVkaWFMaW5rc1NlcnZpY2UtZ2V0TWVkaWFVcmxGb3JJdGVtygIPQXJ0aWNsZXxGZWF0dXJl0gIBWfICAPoCAU6CAwNXZWKKAxxDSUQ6MjAyNTA0MDgxNzEwMTY4ODg6Mjg3MDUw&_s=AH2MYk0kmnJKLtLEtVIDIizdS%2Bw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+and+End+User+Computing&rft.atitle=Developers%2C+Quality+Control+and+Download+Volume+in+Open+Source+Software+%28OSS%29+Projects&rft.au=Hill%2C+Geoffrey%3BDatta%2C+Pratim%3BCandice+Vander+Weerdt.&rft.aulast=Hill&rft.aufirst=Geoffrey&rft.date=2017-04-01&rft.volume=29&rft.issue=2&rft.spage=43&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+and+End+User+Computing&rft.issn=15462234&rft_id=info:doi/10.4018%2FJOEUC.2017040103","Open source software; Open source; Software; Open-source software; Open Source Software; Quality control; Segmented Regression; Software development; Computers--Electronic Data Processing; Developer Limit; Downloading; Quality Control; Quality Control Index; Regression Discontinuity; Tragedy of the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience.

The authors' results indicated that according to the objectives of projects, a proper and planned control for the communication among team members is crucial for the success of OSS projects.","2016","2025-04-25 16:50:21","2025-04-25 16:50:21","","22-44","","4","24","","","","","","","","","","English","","","ABI/INFORM Global","2954645705","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/Xn6YX?_a=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&_s=%2FwNV7XP2puV6PVP%2BhnELVhtmQ2E%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Global+Information+Management&rft.atitle=The+Effects+of+Communication+Patterns+on+the+Success+of+Open+Source+Software+Projects%3A+An+Empirical+Analysis+from+Social+Network+Perspectives&rft.au=Wu%2C+Jing%3BKhim-Yong+Goh%3BHe%2C+Li%3BLuo%2C+Chuan%3BZheng%2C+Haichao.&rft.aulast=Wu&rft.aufirst=Jing&rft.date=2016-10-01&rft.volume=24&rft.issue=4&rft.spage=22&rft.isbn=&rft.btitle=&rft.title=Journal+of+Global+Information+Management&rft.issn=10627375&rft_id=info:doi/10.4018%2FJGIM.2016100102","Open source software; Social network analysis; Data analysis; Business And Economics--Management; Open source; Software; Open-source software; Open Source; Econometrics; Social Network Analysis; Network analysis; Success; Social; Social networks; Economic; Software Projects; Empirical analysis; Social network; Communication Patterns; Panel Data Analysis; Three-Stage Least Squares","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, not of all the FLOSS tools are mature, and failed implementations can occur. Thus, FLOSS evaluation-selection frameworks and FLOSS success-failure implementation factors studies have been conducted. In this research, we advance on such studies through an integrated FLOSS evaluation-selection model with a risk-based decision-making approach. Our model was built upon the other two literatures, and it was structured as a multi-attribute decision-making (MADM) model which contains 12 variables grouped in four risk categories: financial, organisational, end user, and technical ones. We illustrated its utilisation in the domain of information technology service management (ITSM) FLOSS tools. Hence, our model contributes to the FLOSS literature with the inclusion of the risk management approach and to the FLOSS evaluation-selection praxis with the provision of an innovative and essential risk-based model.","2016","2025-04-25 16:50:22","2025-04-25 16:50:22","","326","","4","16","","","","","","","","","","English","","","ABI/INFORM Global","1861798477","","","Place: Geneva Publisher: Inderscience Enterprises Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Technology+Policy+and+Management&rft.atitle=An+MADM+risk-based+evaluation-selection+model+of+free-libre+open+source+software+tools&rft.au=Mora%2C+Manuel%3BG%C3%B3mez%2C+Jorge+Marx%3BO%27Connor%2C+Rory+V%3BGelman%2C+Ovsei.&rft.aulast=Mora&rft.aufirst=Manuel&rft.date=2016-10-01&rft.volume=16&rft.issue=4&rft.spage=326&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Technology+Policy+and+Management&rft.issn=14684322&rft_id=info:doi/","Open source software; Decision making; Information technology; Studies; Open source; Software; Risk management; Programming tool; Technology: Comprehensive Works; Decision making models; IT service management; Multiple criteria decision making","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Passive users play a critical role in the adoption and diffusion of OSS, and we need more research to understand their behaviors and motivations. We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.","2015-08","2025-04-25 16:50:22","2025-04-25 16:50:22","","674-706","","8","16","","","","","","","","","","English","","","ABI/INFORM Global","1711618000","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/OBJ/QFcWV?_a=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%3D%3D&_s=NukQhHdoSs7AKmjonN2p29jHjz0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Loyalty%2C+Ideology%2C+and+Identification%3A+An+Empirical+Study+of+the+Attitudes+and+Behaviors+of+Passive+Users+of+Open+Source+Software&rft.au=Choi%2C+Namjoo%3BChengalur-Smith%2C+Indushobha%3BNevo%2C+Saggi.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-08-01&rft.volume=16&rft.issue=8&rft.spage=674&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Sociology; Identification; Information systems; Community; Studies; User behavior; Marketing; Virtual communities; Open source; Hypotheses; Open-source software; Consumer behavior; Research; Success; Computers--Information Science And Information Theory; Software development; Loyalty; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; 7100:Market research; Consciousness; Ideology; Usability testing; User","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project’s time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project’s progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 16:50:22","2025-04-25 16:50:22","","116","","1","32","","","","","","","","","","English","","","ABI/INFORM Global","1697517813","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+Information+Systems&rft.atitle=Exploitation+and+Exploration+Networks+in+Open+Source+Software+Development%3A+An+Artifact-Level+Analysis%3A+JMIS&rft.au=Temizkan%2C+Orcun%3BKumar%2C+Ram+L.&rft.aulast=Temizkan&rft.aufirst=Orcun&rft.date=2015-07-01&rft.volume=32&rft.issue=1&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+Information+Systems&rft.issn=07421222&rft_id=info:doi/","Open source software; Political Science; Studies; Open source; Software engineering; Software; Open-source software; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 16:50:22","2025-04-25 16:50:22","","119-139","","1","39","","","","","","","","","","English","","","ABI/INFORM Global","1655249846","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/Q0uKV?_a=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&_s=c3Lp6TqythFY%2BWrN%2BTvJkpa1pVs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=Raising+the+general+public%27s+awareness+and+adoption+of+open+source+software+through+social+Q%26amp%3BA+interactions&rft.au=Choi%2C+Namjoo%3BYi%2C+Kwan.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-01-01&rft.volume=39&rft.issue=1&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/","Open source software; Motivation; Qualitative research; Studies; Computers--Internet; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

This increasing attention is a result of the remarkable growth in the number of OSS applications in recent years. Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1,409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest. These findings have implications for both the OSS research community and OSS practitioners.","2015","2025-04-25 16:50:22","2025-04-25 16:50:22","","28","","1","25","","","","","","","","","","English","","","ABI/INFORM Global","1654703565","","","Place: Mahwah Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.atitle=Investigating+the+Interrelationships+among+Success+Measures+of+Open+Source+Software+Projects&rft.au=Ghapanchi%2C+Amir+Hossein.&rft.aulast=Ghapanchi&rft.aufirst=Amir&rft.date=2015-01-01&rft.volume=25&rft.issue=1&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.issn=10919392&rft_id=info:doi/","Open source software; Studies; Open source; Software; Open-source software; Success; Sustainability; Project management; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Software Projects; Project Success; Business And Economics--Computer Applications; Management theory; Release management; Sustainability management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. They also reproduced the results on new data provided by Mozilla. The authors constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-25 16:50:22","2025-04-25 16:50:22","","127-143","","2","39","","","","","","","","","","English","","","ABI/INFORM Global","1929783648","","","Place: Ahmedabad Publisher: Sage Publications, New Delhi India","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Vikalpa&rft.atitle=The+Emergence+of+an+Organizational+Field%3A+The+Case+of+Open+Source+Software&rft.au=Ojha%2C+Abhoy+K%3BRao%2C+Ravi+Anand.&rft.aulast=Ojha&rft.aufirst=Abhoy&rft.date=2014-04-01&rft.volume=39&rft.issue=2&rft.spage=127&rft.isbn=&rft.btitle=&rft.title=Vikalpa&rft.issn=02560909&rft_id=info:doi/10.1177%2F0256090920140211","Open source software; Business And Economics--Management; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them.

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 16:50:23","2025-04-25 16:50:23","","477-512","","4","34","","","","","","","","","","English","","","ABI/INFORM Global","1510748443","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/7E55V?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yPWuXs0jr4o83q1fDVJWcSjQgII%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=International+Journal+of+Operations+%26+Production+Management&rft.atitle=Risk+of+adopting+mission-critical+OSS+applications%3A+an+interpretive+case+study&rft.au=Poba-Nzaou%2C+Placide%3BRaymond%2C+Louis%3BFabi%2C+Bruno.&rft.aulast=Poba-Nzaou&rft.aufirst=Placide&rft.date=2014-04-01&rft.volume=34&rft.issue=4&rft.spage=477&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Operations+%26+Production+Management&rft.issn=01443577&rft_id=info:doi/10.1108%2FIJOPM-03-2012-0117","Open source software; Information technology; Business And Economics--Management; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

We hypothesize that when an IPR enforcement action is filed, user interest and developer activity will be negatively affected in two types of related OSS projects - those that display technology overlap with the OSS application in dispute and business projects that are specific to the disputed OSS platform. We examine two widely publicized lawsuits-SCO v. IBM and FireStar/DataTern v. Red Hat-using data from SourceForge.net. Our difference-in-difference estimates show that in the months following the filing of SCO v. IBM, OSS projects that exhibit high technology overlap with the disputed OSS experienced a 15% greater decline in user interest and 45% less developer activity than projects in the control group; OSS projects that are intended for business and specific to the disputed OSS platform had a 34% greater decline in user interest and 86% less developer activity than the control group. We find similar results following the filing of FireStar/DataTern v. Red Hat. Our results are also robust to a variety of robustness checks, including a falsification exercise and subsample analyses.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated 'copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the 'new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11","2025-04-25 16:50:23","2025-04-25 16:50:23","","597-625","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2089824849","","","Place: Abingdon Publisher: Taylor & Francis LLC","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Free software; Property; Capitalism; Economic theory; Free and open-source software; Profitability; Profits; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One reason for this is project stagnation after developers quit their projects. This fact has motivated researchers to examine the factors that influence developers' intention to continue their participation. One factor is trust among developers. The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey. Our findings indicate that cooperative norms and effective communication engender trust, whereas an accreditation mechanism eliminates distrust. Additionally, trust positively influences their intention to continue participating, whereas distrust negatively influences it.

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the ""virtuous circle"" supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other. Each of these findings is related to the sustainability of these projects.","2013-01","2025-04-25 16:50:23","2025-04-25 16:50:23","","13-19","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473072","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/r92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=w1JsQafjriUDvJXmxD%2Fvc6puLsw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=Sustainability+in+Open+Source+Software+Commons%3A+Lessons+Learned+from+an+Empirical+Study+of+SourceForge+Projects&rft.au=Schweik%2C+Charles+M.&rft.aulast=Schweik&rft.aufirst=Charles&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=13&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; institutional analysis; Collective action; Business And Economics; Collaboration; Open source; open source software; Hypotheses; Open-source software; Research; Success; commons; Sustainable development; Sustainability; Public domain; Software Projects; Programmers; Books; Variables; Information commons; internet-based collaboration; SourceForge","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 16:50:24","2025-04-25 16:50:24","","32-39","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473053","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/y42HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=2t9cyrsjrGTKotUlU5ETuqoVg%2F4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=The+Evolving+Role+of+Open+Source+Software+in+Medicine+and+Health+Services&rft.au=Ingram%2C+David%3BSevket+Seref+Arikan.&rft.aulast=Ingram&rft.aufirst=David&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Research & development--R&D; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 16:50:24","2025-04-25 16:50:24","","28-36","","12","2","","","","","","","","","","English","","","ABI/INFORM Global","1614473125","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/Z92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=GbZFrwogPCXpMB86F2AnR11z97U%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=An+Enterprise+Perspective+on+Customer+Value+Propositions+for+Open+Source+Software&rft.au=Shanker%2C+Aparna.&rft.aulast=Shanker&rft.aufirst=Aparna&rft.date=2012-12-01&rft.volume=2&rft.issue=12&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help ""transfer"" their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

Yet many unanswered questions exist regarding why certain FOSS projects succeed while others fail. Drawing on social capital theory and human agency theory, this study proposes that FOSS projects stand a better chance of success if they possess desirable social network capital and adopt effective strategies. It further argues that valuable social network capital and effective strategies produce greater returns together than they do alone. The results of an empirical analysis reveal significant positive interactions between social capital variables and human agency/strategy variables, highlighting the importance of complementarity between social network ties and strategies in shaping the outcome of FOSS projects.

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS.

By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.","2012-04","2025-04-25 16:50:24","2025-04-25 16:50:24","","920","","4","85","","","","","","","","","","English","","","ABI/INFORM Global","925777279","","","Place: New York Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Systems+and+Software&rft.atitle=Free+and+Open+Source+Software+versus+Internet+content+filtering+and+censorship%3A+A+case+study&rft.au=Shirazi%2C+Farid.&rft.aulast=Shirazi&rft.aufirst=Farid&rft.date=2012-04-01&rft.volume=85&rft.issue=4&rft.spage=920&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Systems+and+Software&rft.issn=01641212&rft_id=info:doi/","Open source software; Studies; Censorship; Open source; Software packages; Internet; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Computers--Software; Free and open-source software; Systems design; 9178:Middle East; Filtering software; Iran","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects evolve and transform over time; therefore success must be examined longitudinally over a period of time. In this research, we examine two measures of project success: project popularity and developer activity, of 283 OSS projects over a span of 3 years, in order to observe changes over time. A comprehensive research model of OSS success is developed which includes both extrinsic and intrinsic attributes. Results show that while many of the hypothesized relationships are supported, there were marked differences in some of the relationships at different points in time lending support to the notion that different factors need to be emphasized as the OSS project unfolds over time.

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 16:50:24","2025-04-25 16:50:24","","156-187","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1018105738","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/wxbVU?_a=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%3D%3D&_s=X0oQ4nOZDi9uA5E9tyFKZJTP08c%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Information+Technology+%26+People&rft.atitle=Adoption+of+free%2Flibre+open+source+software+in+public+organizations%3A+factors+of+impact&rft.au=Rossi%2C+Bruno%3BRusso%2C+Barbara%3BSucci%2C+Giancarlo.&rft.aulast=Rossi&rft.aufirst=Bruno&rft.date=2012-04-01&rft.volume=25&rft.issue=2&rft.spage=156&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593841211232677","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Technology; Case studies; Technology adoption; Migration; Adoption; Case study; 5240:Software & systems; Public domain; Innovations; Public sector; 9130:Experimental/theoretical; Open standards; Cost control; Business process re-engineering; Disruptive innovation; Environmental factor; Library And Information Sciences--Computer Applications; Software services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

So it was important to reassess the factors enabling OSS adoption in order to enhance OSS utilization within public sector organisations. This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-25 16:50:25","2025-04-25 16:50:25","","","","2","17","","","","","","","","","","English","","","ABI/INFORM Global","2546081220","","","Place: Wollongong Publisher: Australasian Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/na1qJ?_a=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%3D%3D&_s=N0WDCOWv2H3E1ddURTiZTg8qVwo%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Australasian+Journal+of+Information+Systems&rft.atitle=Enablers+of+Open+Source+Software+adoption%3A+A+case+study+of+APS+organisations&rft.au=Gurusamy%2C+Kavitha%3BCampbell%2C+John.&rft.aulast=Gurusamy&rft.aufirst=Kavitha&rft.date=2012-01-01&rft.volume=17&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Australasian+Journal+of+Information+Systems&rft.issn=14498618&rft_id=info:doi/10.3127%2Fajis.v17i2.731","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Computers--Computer Systems; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

For these companies, choosing the correct license determines business success. When the available open source stack and licensing options grow, so does the need to understand the interplay among licensing, sourcing decisions, and business goals. A model of license choice emphasizes different licenses and rationalizes the choice of an open source software (OSS) license. This is crucial for smaller companies and start-ups that don't have the tools and knowledge to perform a thorough investigation of all the consequences of their license choice every time they employ OSS.

Drawing on research in information systems and sociology, this study develops and evaluates an integrated model for the acceptance of OSS. In addition to the traditional technology adoption variables the findings stress the importance of social identification as a key driver of OSS adoption. The proposed model provides a useful decision support tool for assessing and proactively designing interventions targeted at successful OSS adoption and diffusion.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ''joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community.

Recently, the focus has shifted toward an examination of a newer construct -temporal dispersion (TD). The study of TD so far has been constrained mostly to conceptual work. This study furthers the understanding of TD through an empirical investigation of its relationship with open source software (OSS) team performance. In this paper, hypotheses are developed based on coordination theory, and analyses are performed using data collected from multiple archival sources comprising 100 OSS development teams. Results indicate that TD positively affects development speed and quality and that software complexity moderates the relation between TD and software quality. Theoretical and practical implications are discussed.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-25 16:50:27","2025-04-25 16:50:27","","656","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","196420145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Using+the+DEMO+methodology+for+modeling+open+source+software+development+processes&rft.au=Huysmans%2C+Philip%3BVen%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Huysmans&rft.aufirst=Philip&rft.date=2010-06-01&rft.volume=52&rft.issue=6&rft.spage=656&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Computers--Data Base Management; Ontology; Demo; Process modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and tribal knowledge that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 16:50:27","2025-04-25 16:50:27","","211-223","","2","28","","","","","","","","","","English","","","ABI/INFORM Global","521142269","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/qPQuT?_a=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&_s=R3D%2FTgQI5szaHaGdFb%2BVEn%2FrVUA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+economy+of+free+and+open+source+software+in+the+preservation+of+digital+artefacts&rft.au=Morrissey%2C+Sheila.&rft.aulast=Morrissey&rft.aufirst=Sheila&rft.date=2010-04-01&rft.volume=28&rft.issue=2&rft.spage=211&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2F07378831011047622","Open source software; Studies; Open source; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Library And Information Sciences--Computer Applications; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software maintenance is required to fix bugs, to add new features, to improve performance, and/or to adapt to a changed environment. In this article, we examine change in cognitive complexity and its impacts on maintenance in the context of open source software (OSS). Relationships of the change in cognitive complexity with the change in the number of reported bugs, time taken to fix the bugs, and contributions from new developers are examined and are all found to be statistically significant. In addition, several control variables, such as software size, age, development status, and programmer skills are included in the analyses. The results have strong implications for OSS project administrators; they must continually measure software complexity and be actively involved in managing it in order to have successful and sustainable OSS products.

This study addresses the interactive collaboration in these kinds of communities applying social network analysis (SNA). In particular, SNA techniques will be used to identify those members playing a middle-man role among other community members. Results will illustrate the importance of this role to achieve successful virtual communities.

We test the hypothesis that skill variety of participants is associated with project performance. We also explore whether the level of modularization of project activities is correlated with performance. Our econometric estimations show that skill heterogeneity is associated with project survival and performance. However, the relationship between skill diversity and performance is non-monotonic. Design modularity is also positively associated with the performance of the project. Finally, the interaction between skill heterogeneity and modularity is negatively associated with performance.

Understanding the factors that affect the involvement and contributions of participants in OSS projects is of significance to facilitate project success. This paper investigates the effects of motivation on participant performance in OSS projects, drawing upon self-determination theory to examine how task effort (i. e., effort intensity and goal commitment) mediates the relationships between a spectrum of motivations and individual performance. The research model is supported by survey data from 204 participants in OSS projects. The theoretical contributions and managerial implications are discussed.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.

While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

A large data set retrieved from a project repository is used to test these hypotheses. The main results are that if Norden-Rayleigh-based approaches are used, they need to be complemented in order to account for the addition of new features during a product life cycle, and that programmer-participation based effort models result in distinctly lower estimations of effort than those based on output metrics, such as lines of code.

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-25 16:50:28","2025-04-25 16:50:28","","449-462","","5","16","","","","","","","","","","English","","","ABI/INFORM Global","212365312","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/b6OaT?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yiXUHeA3Bd5m9qlApbZJ63Be1aM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Management+%26+Computer+Security&rft.atitle=Evaluating+the+performance+of+open+source+software+projects+using+data+envelopment+analysis&rft.au=Wray%2C+Barry%3BMathieu%2C+Richard.&rft.aulast=Wray&rft.aufirst=Barry&rft.date=2008-10-20&rft.volume=16&rft.issue=5&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Information+Management+%26+Computer+Security&rft.issn=09685227&rft_id=info:doi/10.1108%2F09685220810920530","Open source software; Studies; Productivity; Business And Economics--Management; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-25 16:50:29","2025-04-25 16:50:29","","142-156","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","211770348","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aQ4UT?_a=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&_s=skz%2By9xiJklpExxCBn8Dys3vIXk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Innovation+Management&rft.atitle=Online+innovation%3A+the+case+of+open+source+software+development&rft.au=Vujovic%2C+Sladjana%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=Vujovic&rft.aufirst=Sladjana&rft.date=2008-01-01&rft.volume=11&rft.issue=1&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Innovation+Management&rft.issn=14601060&rft_id=info:doi/10.1108%2F14601060810845268","Open source software; Innovation; Communication; Information technology; Studies; Business And Economics--Management; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Public domain; Technological change; Innovations; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Following a case study methodology, we examined developer interaction data from three active and successful FLOSS projects using qualitative research methods, specifically inductive content analysis, to identify the task-assignment mechanisms used by the participants. We found that 'self-assignment' was the most common mechanism across three FLOSS projects. This mechanism is consistent with expectations for distributed and largely volunteer teams. We conclude by discussing whether these emergent practices can be usefully transferred to mainstream practice and indicating directions for future research.

Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

This paper develops and tests a model of the impacts of license restrictiveness and organizational sponsorship on two indicators of success: user interest in, and development activity on, open source software development projects. Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.

Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied - especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 16:50:30","2025-04-25 16:50:30","","227-238","","2","44","","","","","","","","","","English","","","ABI/INFORM Global","222420968","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/ORIG/5/G0cEE?_a=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&_s=SVgzekDe95rQdVHfJ2Zo%2BltJgw0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Systems+Journal&rft.atitle=The+value+of+open+standards+and+open-source+software+in+government+environments&rft.au=Simon%2C+K+D.&rft.aulast=Simon&rft.aufirst=K&rft.date=2005-04-01&rft.volume=44&rft.issue=2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=IBM+Systems+Journal&rft.issn=00188670&rft_id=info:doi/","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-25 16:50:30","2025-04-25 16:50:30","","","","2","48","","","","","","","","","","English","","","ABI/INFORM Global","237056523","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Open+source+software+for+medical+image+processing+and+visualization&rft.au=Yoo%2C+Terry+S%3BAckerman%2C+Michael+J.&rft.aulast=Yoo&rft.aufirst=Terry&rft.date=2005-02-01&rft.volume=48&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/10.1145%2F1042091.1042120","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Research & development--R&D; United States--US; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Computers--Data Communications And Data Transmission Systems; Digital image processing; Image; Medical imaging","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research investigates the evolution of open source software using a case study of the Samba project. Through the application of both qualitative and quantitative techniques, Samba's software development and evolution over a seven-year period are tracked and assessed. This assessment and the findings of similar, previously reported studies lead us to propose a general framework for the evolution and the key drivers of open source software evolution.

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-25 16:50:30","2025-04-25 16:50:30","","94-112","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","821692253","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/8v97U?_a=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&_s=pUsDcFs3MVZkPLVZxMuyqK90UPQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Open+source+software+and+software+patents%3A+A+constitutional+perspective&rft.au=Pfaffenberger%2C+Bryan.&rft.aulast=Pfaffenberger&rft.aufirst=Bryan&rft.date=1999-10-01&rft.volume=12&rft.issue=3&rft.spage=94&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-999-1029-x","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 16:52:06","2025-04-25 16:52:06","","1449–1469","","4","63","","","","","","","","","","English","","","","","","","","","","","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures; Business And Economics–Small Business","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study presents a model for health-sustaining activities in public-sector FOSS ecosystems. Orchestrators and keystone players are found to engage in health-sustaining activities through rulemaking, role creation, and tool provision, hinting at the explanatory potential of Activity Theory. Furthermore, the study identifies key challenges in orchestrating public sector FOSS ecosystems, such as institutional misalignment and conflicting policy frameworks, highlighting these as critical areas for future research.","2024","2025-04-25 16:52:06","2025-04-25 16:52:06","","","","2","36","","","","","","","","","","English","","","","","","","","","","","Open source software; governance; FOSS; Computers; Free software; open-source software; software ecosystem; Public domain; ecosystem health; Misalignment; orchestration; Players; public sector; Public sector; Qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-25 16:52:07","2025-04-25 16:52:07","","361","","1","47","","","","","","","","","","English","","","","","","","","","","","Open source software; COVID-19; Computers; Resilience; Pandemics; Public health; Community; Open source; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Nature conservation; Resource conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023","2025-04-25 16:52:07","2025-04-25 16:52:07","","3106–3130","","5","49","","","","","","","","","","English","","","","","","","","","","","Open source software; Organizations; Mentors; Motivation; Data analysis; Students; Open-source software; Task analysis; Strategy; Mentoring; Sustainability; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; taxonomy; Challenge; mentoring process; Mentorship; newcomer onboarding; summer of code; Computers–Software","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers’ early careers and hence shed light on future research in this direction.","2023","2025-04-25 16:52:07","2025-04-25 16:52:07","","529–548","","2","49","","","","","","","","","","English","","","","","","","","","","","Careers; open source; Task analysis; Ecosystems; Success; Documentation; Engineering profession; Codes; Correlation; Newcomer; Focusing; Statistical analysis; Empirical analysis; Dynamic contribution pattern; early career; newcomer; technical success; Computers–Software","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time.

We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation.

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 16:52:08","2025-04-25 16:52:08","","8","","","49","","","","","","","","","","English","","","","","","","","","","","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling; Computers–Information Science And Information Theory","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been institutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous security in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed security controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices.

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 16:52:08","2025-04-25 16:52:08","","1439","","3","44","","","","","","","","","","English","","","","","","","","","","","Open source software; Computers; Open source; Software; Open-source software; Signaling; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for‐profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 16:52:08","2025-04-25 16:52:08","","369–402","","2","30","","","","","","","","","","English","","","","","","","","","","","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles; Computers–Computer Systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 16:52:08","2025-04-25 16:52:08","","20","","","46","","","","","","","","","","English","","","","","","","","","","","Open source software; Decision making; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution; Computers–Information Science And Information Theory","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 16:52:08","2025-04-25 16:52:08","","764","","3","30","","","","","","","","","","English","","","","","","","","","","","Open source software; Organizations; Motivation; Open source; Software engineering; Open-source software; Computer architecture; Ownership; Success; Project management; Software development; Freeware; Modular design; Project Success; Superposition; Computers–Information Science And Information Theory; 51821:Computing Infrastructure Providers; and Related Services; Data Processing; Web Hosting","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Only a few empirical studies investigate how the choice of components is conducted in industrial practice. This is important to understand to tailor research solutions to the needs of the industry. Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better. Interestingly, the final decision was perceived negatively in nine cases and positively in seven cases, while in the remaining cases it was perceived as neither positive nor negative.","2018","2025-04-25 16:52:08","2025-04-25 16:52:08","","237–261","","3","44","","","","","","","","","","English","","","","","","","","","","","Decision making; Outsourcing; OSS; Software; Computer architecture; outsourcing; Companies; Industries; Component-based software engineering; COTS; in-house; Computers–Software","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities.

We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement.

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project’s time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project’s progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 16:52:10","2025-04-25 16:52:10","","116","","1","32","","","","","","","","","","English","","","","","","","","","","","Open source software; Political Science; Studies; Open source; Software engineering; Software; Open-source software; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 16:52:10","2025-04-25 16:52:10","","119–139","","1","39","","","","","","","","","","English","","","","","","","","","","","Open source software; Motivation; Qualitative research; Studies; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1,409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-25 16:52:10","2025-04-25 16:52:10","","127–143","","2","39","","","","","","","","","","English","","","","","","","","","","","Open source software; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries; Business And Economics–Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment.

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 16:52:11","2025-04-25 16:52:11","","477–512","","4","34","","","","","","","","","","English","","","","","","","","","","","Open source software; Information technology; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical; Business And Economics–Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

We examine two widely publicized lawsuits-SCO v. IBM and FireStar/DataTern v. Red Hat-using data from SourceForge.net. Our difference-in-difference estimates show that in the months following the filing of SCO v.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated 'copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the 'new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11","2025-04-25 16:52:11","2025-04-25 16:52:11","","597–625","","4","42","","","","","","","","","","English","","","","","","","","","","","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Free software; Property; Capitalism; Economic theory; Free and open-source software; Profitability; Profits; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One reason for this is project stagnation after developers quit their projects. This fact has motivated researchers to examine the factors that influence developers' intention to continue their participation. One factor is trust among developers. The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey. Our findings indicate that cooperative norms and effective communication engender trust, whereas an accreditation mechanism eliminates distrust. Additionally, trust positively influences their intention to continue participating, whereas distrust negatively influences it.

In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the ""virtuous circle"" supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other.

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 16:52:12","2025-04-25 16:52:12","","32–39","","1","3","","","","","","","","","","English","","","","","","","","","","","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based; Research & development–R&D","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 16:52:12","2025-04-25 16:52:12","","28–36","","12","2","","","","","","","","","","English","","","","","","","","","","","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses.

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS.

They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 16:52:13","2025-04-25 16:52:13","","156–187","","2","25","","","","","","","","","","English","","","","","","","","","","","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Technology; Case studies; Technology adoption; Migration; Adoption; Case study; 5240:Software & systems; Public domain; Innovations; Public sector; 9130:Experimental/theoretical; Open standards; Cost control; Business process re-engineering; Disruptive innovation; Environmental factor; Software services; Library And Information Sciences–Computer Applications","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

So it was important to reassess the factors enabling OSS adoption in order to enhance OSS utilization within public sector organisations. This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-25 16:52:13","2025-04-25 16:52:13","","","","2","17","","","","","","","","","","English","","","","","","","","","","","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization; Computers–Computer Systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.

Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-25 16:52:14","2025-04-25 16:52:14","","656","","6","52","","","","","","","","","","English","","","","","","","","","","","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Ontology; Demo; Process modeling; Computers–Data Base Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and tribal knowledge that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 16:52:14","2025-04-25 16:52:14","","211–223","","2","28","","","","","","","","","","English","","","","","","","","","","","Open source software; Studies; Open source; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design; Library And Information Sciences–Computer Applications","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Relationships of the change in cognitive complexity with the change in the number of reported bugs, time taken to fix the bugs, and contributions from new developers are examined and are all found to be statistically significant. In addition, several control variables, such as software size, age, development status, and programmer skills are included in the analyses.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.

While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.

We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code).

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

A large data set retrieved from a project repository is used to test these hypotheses. The main results are that if Norden-Rayleigh-based approaches are used, they need to be complemented in order to account for the addition of new features during a product life cycle, and that programmer-participation based effort models result in distinctly lower estimations of effort than those based on output metrics, such as lines of code.

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-25 16:52:16","2025-04-25 16:52:16","","449–462","","5","16","","","","","","","","","","English","","","","","","","","","","","Open source software; Studies; Productivity; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming; Business And Economics–Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.

However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-25 16:52:16","2025-04-25 16:52:16","","142–156","","1","11","","","","","","","","","","English","","","","","","","","","","","Open source software; Innovation; Communication; Information technology; Studies; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Public domain; Technological change; Innovations; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor; United States–US; Business And Economics–Management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied - especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 16:52:18","2025-04-25 16:52:18","","227–238","","2","44","","","","","","","","","","English","","","","","","","","","","","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-25 16:52:18","2025-04-25 16:52:18","","","","2","48","","","","","","","","","","English","","","","","","","","","","","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Digital image processing; Image; Medical imaging; United States–US; Research & development–R&D; Computers–Data Communications And Data Transmission Systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.–Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-25 16:52:18","2025-04-25 16:52:18","","94–112","","3","12","","","","","","","","","","English","","","","","","","","","","","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context.

For the OSS projects to stay sustainable, i.e., viable and maintained over time without interruption or weakening, maintenance labor requires an underlying infrastructure to be supported and secured. Aims: Using the construct of human infrastructure, our study aims to investigate how maintenance labor can be supported and secured to enable the creation and maintenance of sustainable OSS projects, viewed from the maintainers’ perspective. Method: In our exploration, we interviewed ten maintainers from nine well-adopted OSS projects. We coded the data in two steps using investigator-triangulation. Results: We constructed a framework of infrastructure design that provide insight for OSS projects in the design of their human infrastructure. The framework specifically highlight the importance of human factors, e.g., securing a work-life balance and proactively managing social pressure, toxicity, and diversity. We also note both differences and overlaps in how the infrastructure needs to support and secure maintenance labor from maintainers and the wider OSS community, respectively.

However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer.

There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.","2023","2025-04-25 16:52:20","2025-04-25 16:52:20","","180–190","","","","","","","dg.o '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","GitHub; open source software; government; barriers; benefits; citizen engagement; evidence","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Substantial research was done to investigate central projects such as Linux kernel but we have only a limited understanding of how the periphery of the larger OSS ecosystem is interconnected through technical dependencies, code sharing, and knowledge flows. We aim to close this gap by a) creating a nearly complete and rapidly updateable collection of version control data for FLOSS projects; b) by cleaning, correcting, and augmenting the data to measure several types of dependencies among code, developers, and projects; c) by creating models that rely on the resulting supply chains to investigate structural and dynamic properties of the entire OSS. The current implementation is capable of being updated each month, occupies over 300Tb of disk space with 1.5B commits and 12B git objects. Highly accurate algorithms to correct identity data and extract dependencies from the source code are used to characterize the current structure of OSS and the way it has evolved. In particular, models of technology spread demonstrate the implicit factors developers use when choosing software components. We expect the resulting research platform will both spur investigations on how the huge periphery in OSS both sustains and is sustained by the central OSS projects and, as a result, will increase resiliency and effectiveness of the OSS.","2019","2025-04-25 16:52:20","2025-04-25 16:52:20","","3","","","","","","","ESEC/FSE 2019","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","Software Ecosystems; Empirical Software Engineering; Software Measurement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors’ learning processes is an important research area in OSS.This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education.

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project’s capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of sub-topics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project’s overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.","2022","2025-04-25 16:52:20","2025-04-25 16:52:20","","","","","","","","","OpenSym '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","Health; Open Source Software; Sustainability; Software Ecosystem; Software Quality.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process.It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market.In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-04-25 16:52:20","2025-04-25 16:52:20","","1073–1083","","","","","","","ICSE '19","","","","IEEE Press","","","","","","","","","","","","","open source; motivation; code review","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result.

However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSS coach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process. However, there is also some indication that FLOSS coach did not lower the technical barriers.","2015","2025-04-25 16:52:20","2025-04-25 16:52:20","","160–169","","","","","","","SBES '15","","","","IEEE Computer Society","USA","","","","","","","","","","","","open source; newcomers; onboarding; contribution barriers; self-efficacy","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Objective: The goal of this research is to test Eric Raymond's assertions with respect to OSS success factors. Method: We present four criteria by which to assess project reflexivity in SourceForge. These criteria are based on three specific indicators: intended audiences, relevant topics, and supported operating systems. Results: We show in this short paper that 68% of SourceForge projects are likely reflexive (in the sense described by Raymond). Further, 76% of projects exceeding one million downloads are reflexive, 79% for projects exceeding ten million downloads, and 89% for projects exceeding one hundred million downloads. Conclusion: These results tentatively support Raymond's assertions that 1) OSS projects tend to be reflexive and 2) reflexive OSS projects tend to be more successful than irreflexive projects.

In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes.

However, in most of the projects, there is limited amount of information available in the early stages and significant effort is spent for size measurement and effort estimation with such methods. This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software. For this purpose, we consider open source project management and game software. We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., Conceptual) and solution domain (i.e., Design) models. The results reveal a high correlation between the number of conceptual classes in the problem domain model and the number of software classes constituting the corresponding software.

This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review, (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects, (iii) 24 responses to a questionnaire sent to 9 OSS projects, and (iv) semi-structured interviews with 36 sub-jects from 14 different projects, including newcomers and experi-enced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practi-tioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteris-tics, reception issues, orientation, technical hurdles, and docu-mentation problems. We could observe recurrent barriers evi-denced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-04-25 16:52:21","2025-04-25 16:52:21","","51–60","","","","","","","ARES '14","","","","IEEE Computer Society","USA","","","","","","","","","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is therefore important to understand how and why potential contributors fail in the process of transitioning from user to contributor. Most newcomers, or ""newbies"", have their first interaction with a community through a mailing list. To understand how this first contact influences future interactions, we studied eight mailing lists across four FOSS projects: MediaWiki, GIMP, PostgreSQL, and Subversion. We analyzed discussions initiated by newbies to determine the effect of gender, nationality, politeness, helpfulness and timeliness of response. We found that nearly 80% of newbie posts received replies, and that receiving timely responses, especially within 48 hours, was positively correlated with future participation.

Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world. OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization’s success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems. The main aim of this paper is to measure the evolution of OSS using, Eclipse Metrics (EM), with Guice software (GS) as a case study.

To understand how this ""natural product evolution"" happens, we have conducted a case study of four typical OSS projects. Unlike most previous studies on software evolution that focus on the evolution of the system per se, our study takes a broader perspective: It examines not only the evolution of OSS systems, but also the evolution of the associated OSS communities, as well as the relationship between the two types of evolution.Through the case study, we have found that while collaborative development within a community is the essential characteristic of OSS, different collaboration models exist, and that the difference in collaboration model results in different evolution patterns of OSS systems and communities. To treat such differences systematically, we propose to classify OSS into three types: Exploration-Oriented, Utility-Oriented, and Service-Oriented. Such a classification can provide guidance on the creation and maintenance of sustainable OSS development and communities.","2002","2025-04-25 16:52:23","2025-04-25 16:52:23","","76–85","","","","","","","IWPSE '02","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","case study; software evolution; open-source software (OSS); open-source software community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The paper finds that as users become more skilled in OSS, the price of proprietary software will decline. Second, the equilibrium market structure is influenced by both users' expertise and network effects. It is not surprising that proprietary software can drive OSS out of the market in presence of network effect, but counter-intuitively, this happens when users are highly skilled in OSS.

We examine in detail the faults that occur in three, large, open-source applications: the Apache web server, the GNOME desktop environment, and the MySQL database. Using information contained in the bug reports and source code, we classify faults based on how they depend on the operating environment. We find that 72-87% of the faults are independent of the operating environment and are hence deterministic (non-transient). Recovering from the failures caused by these faults requires the use of application-specific knowledge. Half of the remaining faults depend on a condition in the operating environment that is likely to persist on retry, and the failures caused by these faults are likely to require application-specific recovery. Unfortunately, only 5-14% of the faults were triggered by transient conditions, such as timing and synchronization that naturally fix them during recovery. Our results indicate that classical application-generic recovery techniques, such as process pairs, will not be sufficient to enable applications to survive most failures caused by application faults.","2000","2025-04-25 16:52:24","2025-04-25 16:52:24","","97–106","","","","","","","DSN '00","","","","IEEE Computer Society","USA","","","","","","","","","","","","Software; Faults; Heisenbugs; Recovery; Transient","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Structural complexity, an architectural concern, makes software projects more difficult to understand, and consequently more difficult to maintain and evolve. The contributors in a free software project exhibit different levels of participation in the project, and can be categorized as core and peripheral developers. Research aim: This research aims at characterising the changes made to the source code of 7 web server projects written in C with respect to the amount of structural complexity added or removed and the developer level of participation. Method: We performed a observational study with historical data collected from the version control repositories of those projects, recording structural complexity information for each change as well as identifying each change as performed by a core or a peripheral developer. Results and conclusions: We have found that core developers introduce less structural complexity than peripheral developers in general, and that in the case of complexity-reducing activities, core developers remove more structural complexity than peripheral developers. These results demonstrate the importance of having a stable and healthy core team to the sustainability of free software projects.","2010","2025-04-25 16:52:24","2025-04-25 16:52:24","","21–29","","","","","","","SBES '10","","","","IEEE Computer Society","USA","","","","","","","","","","","","FLOSS; Free Software; Open Source software; Empirical Software Engineering; Core and Periphery; Structural Complexity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs).

Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data.

Companies get involved in FLOSS projects to acquire user innovations [3, 12], to reduce costs [8, 11], to make money on complementary services [13], etc. Such intense involvement may change the nature of FLOSS development and pose critical challenges for the sustainability of the projects. For example, it has been found that a company's full control and intense involvement is associated with a decrease of volunteer inflow [13]. Sometimes a project may fail after one company pulls resources from the project [13]. This raises concerns about the domination of one company in a project. In large projects like OpenStack, there are often hundreds of companies involved in contributing code. Despite substantial researches on commercial participation, whether or not one company dominates a project and the impact of such domination has never been explicitly explored. We investigate four main projects of OpenStack, a large ecosystem that has had a tremendous impact on computing and society, to answer the following research questions: Does one company dominate the project's development (RQ1)? If the answer to RQ1 is yes, does the domination affect the community (RQ2)?","2018","2025-04-25 16:52:24","2025-04-25 16:52:24","","440–441","","","","","","","ICSE '18","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent research has linked these problems to the values of Lyapunov exponents for the forward-dynamics, which describe the growth or shrinkage of infinitesimal perturbations. Here, we propose gradient flossing, a novel approach to tackling gradient instability by pushing Lyapunov exponents of the forward dynamics toward zero during learning. We achieve this by regularizing Lyapunov exponents through backpropagation using differentiable linear algebra. This enables us to ""floss"" the gradients, stabilizing them and thus improving network training. We demonstrate that gradient flossing controls not only the gradient norm but also the condition number of the long-term Jacobian, facilitating multidimensional error feedback propagation. We find that applying gradient flossing prior to training enhances both the success rate and convergence speed for tasks involving long time horizons. For challenging tasks, we show that gradient flossing during training can further increase the time horizon that can be bridged by backpropagation through time. Moreover, we demonstrate the effectiveness of our approach on various RNN architectures and tasks of variable temporal complexity. Additionally, we provide a simple implementation of our gradient flossing algorithm that can be used in practice. Our results indicate that gradient flossing via regularizing Lyapunov exponents can significantly enhance the effectiveness of RNN training and mitigate the exploding and vanishing gradients problem.","2023","2025-04-25 16:52:24","2025-04-25 16:52:24","","","","","","","","","NIPS '23","","","","Curran Associates Inc.","Red Hook, NY, USA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level.In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-04-25 16:52:24","2025-04-25 16:52:24","","2366–2380","","","","","","","CCS '23","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","patch backporting; patch semantics; patch type","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions’ adequacy (75% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file.

We apply the latter to 300 open source applications, invest 34 h in manual sample validation, and derive precision rates for each OWASP class.Our validation shows that the rules correctly detected weaknesses for seven OWASP classes with 86% precision, demonstrating the tool’s utility. Yet, we estimate that most findings are not exploitable (81%). Thus, there is still considerable assessment overhead for users. Our work further highlights that only a subset of weaknesses are detectable, as dimensions such as runtime context and insecure design remain hidden. Finally, we advise practitioners to not exclusively rely on public rules, as translating application-specific business logic and design choices may open up to the detection of previously uncovered weaknesses.","2024","2025-04-25 16:52:25","2025-04-25 16:52:25","","64–83","","","","","","","","","","","Springer-Verlag","Berlin, Heidelberg","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer.

To keep this foundation intact, the open source community needs to actively invest in sustainable approaches to bring in new contributors and nurture existing ones. We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a ""rising contributor"" badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.Open Source Software (OSS) plays an important role in the development and maintenance of software products that are widely deployed in different domains from computer science to astrophysics and cutting edge medicines research. Chances are there is an open source project for anyone to contribute to. With the recent deployment of the popular Linux open source project on Mars even the sky is no limit. However, OSS projects largely depend on volunteers and attracting, retaining, and keeping contributors engaged is a severe challenge. In this paper, we present the design and evaluation of a dashboard to support community managers, such as maintainers, to track and acknowledge newcomers' contributions. With the support of tools such as ours, maintainers will be better prepared to attract and retain their emerging community.","2022","2025-04-25 16:52:25","2025-04-25 16:52:25","","36–40","","","","","","","ICSE-SEIS '22","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","open source; maintainers; social good","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While previous research recognizes the significance of trust in an organizational setting, there is a lack of understanding in how trust is exhibited in OSS distributed teams, where there is an absence of direct, in-person communications. To foster trust and collaboration in OSS teams, we need to understand what trust is and how it is exhibited in written developer communications (e.g., pull requests, chats). In this paper, we first investigate various dimensions of trust to identify the ways trusting behavior can be observed in OSS. Next, we sample a set of 100 GitHub pull requests from Apache Software Foundation (ASF) projects, to analyze and demonstrate how each dimension of trust can be exhibited. Our findings provide preliminary insights into cues that might be helpful to automatically assess team dynamics and establish interpersonal trust in OSS teams, leading to successful and sustainable OSS.","2023","2025-04-25 16:52:25","2025-04-25 16:52:25","","19–24","","","","","","","ICSE-NIER '23","","","","IEEE Press","","","","","","","","","","","","","open source software; trust; pull requests","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The recent growth in demand for professional software engineers has led to increased contributions to, and usage of, OSS. However, there is limited understanding of the factors affecting how developers, and how new or student developers in particular, decide which OSS projects to contribute to, a process critical to OSS sustainability, access, adoption, and growth. To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (𝑝 < 0.0001, effect size = 0.84), student motivation (𝑝 < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (𝑝 < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner. Our findings may help improve the experience for new developers participating in OSS4SG and the quality of their contributions. We also hope our work helps educators, project leaders, and contributors to build a mutually-beneficial framework for the future growth of OSS4SG.","2023","2025-04-25 16:52:26","2025-04-25 16:52:26","","3–15","","","","","","","ESEC/FSE 2023","","","","Association for Computing Machinery","New York, NY, USA","","","","","","","","","","","","Open Source Software; CS Education; Social Good","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Due to a lack of sustained contributors, however, most FLOSS projects do not survive. The early identification of developers who are likely to remain is thus an eminent challenge for the management of FLOSS initiatives. Previous research has shown that individuals' subjective assessment is often inaccurate emphasizing the need to objectively evaluate retention behavior. Consistent with the concepts Person-Job (P-J) and Person-Team (P-T) fit from the traditional recruitment literature, we derive objective measures to predict developer retention in FLOSS projects. In an analysis of the contribution behavior of former Google Summer of Code (GSoC) students we reveal that the level of development experience and conversational knowledge is strongly associated with retention. Surprisingly, our analysis reveals that students with abilities that are underrepresented in the project and students with a higher academic education do not remain considerably longer.","2012","2025-04-25 16:52:26","2025-04-25 16:52:26","","3446–3455","","","","","","","HICSS '12","","","","IEEE Computer Society","USA","","","","","","","","","","","","Open source; Open Source Software; Open source software development; Developer Retention; IS personnel; OSS/FLOSS; Recruiting; Team staffing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails. These emails contain decisions for 466 Python Enhancement Proposals (PEPs) that document the language’s evolution.

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors ('problem solvers') tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs ('problems') tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between 'core' and 'peripheral' members identified exclusively on the basis of their individual level of contribution to the project.

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making 'good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.

While some technologies are inherently political, other technologies become politicized through competition among different groups and organizations. How do seemingly apolitical technologies become politicized? In this article, the author examines the case of the ""circuit riders,"" a progressive technology movement in the United States that promotes information technology use among nonprofit and grassroots organizations, to show how a particular technology is politicized through field-level interactions. Applying and contributing to actor-network theory, the author finds that translation takes place as an organizational process by which actors associate the ideals of the technology in question with their political ideals and then attempt to enroll other actors to accept the resultant associations. Successful association depends on both discursive and organizational practices.

Owing to the unrestricted access to source code, version control information, and bug tracking database, a comprehensive study on the Development Process associated with an OSS project is feasible. In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.","2025-03","2025-04-25 16:56:33","2025-04-25 16:56:33","","4","","1","33","","","","","","","","","","English","","","ABI/INFORM Global","3145911815","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Quality+enhancement+in+OSS+development+process%3A+a+quantitative+framework+approach&rft.au=.&rft.aulast=&rft.aufirst=&rft.date=2025-03-01&rft.volume=33&rft.issue=1&rft.spage=4&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-024-09705-0","Open source software; GitHub; Software quality; Resource allocation; Computers--Software; Source code; Decision analysis; Comparative analysis; Quality assessment; Operations research; Quantitative analysis; Multiple criteria decision making; Development process; Multi-criteria decision analysis; Multiple criterion; Project feasibility; Version control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 16:56:33","2025-04-25 16:56:33","","1449-1469","","4","63","","","","","","","","","","English","","","ABI/INFORM Global","3129871390","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Small+Business+Economics&rft.atitle=Financing+A+Free-for-All%3A+Crowdfunding+Open-Source+Software&rft.au=Bort%2C+James%3BMeoli%2C+Azzurra%3BSullivan%2C+David+W..&rft.aulast=Bort&rft.aufirst=James&rft.date=2024-12-01&rft.volume=63&rft.issue=4&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Small+Business+Economics&rft.issn=0921898X&rft_id=info:doi/10.1007%2Fs11187-023-00867-y","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business And Economics--Small Business; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While these initiatives hold significant promise, they frequently encounter hurdles like poor productivity, leading to premature demise. This study explores activities that contribute to the long-term well-being of public-sector FOSS ecosystems, focusing on public-sector entities as orchestrators and keystone players. A qualitative multi-case study of three ecosystems was conducted, with data collected through interviews, participant observation, and analysis of online discussion forums. The study presents a model for health-sustaining activities in public-sector FOSS ecosystems. Orchestrators and keystone players are found to engage in health-sustaining activities through rulemaking, role creation, and tool provision, hinting at the explanatory potential of Activity Theory. Furthermore, the study identifies key challenges in orchestrating public sector FOSS ecosystems, such as institutional misalignment and conflicting policy frameworks, highlighting these as critical areas for future research.","2024","2025-04-25 16:56:34","2025-04-25 16:56:34","","","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","3152500844","","","Place: Aalborg Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/lP17b?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=CbtWqrxs3u%2BJGoCCoKC1Vx6zM30%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Scandinavian+Journal+of+Information+Systems&rft.atitle=Health+and+Orchestration+of+Public-Sector+Open-Source+Software+Ecosystems+Roles%2C+rules+and+tools&rft.au=Henttonen%2C+Katja+M%3BPulkkinen%2C+Mirja%3BTyrvainen%2C+Pasi.&rft.aulast=Henttonen&rft.aufirst=Katja&rft.date=2024-01-01&rft.volume=36&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Scandinavian+Journal+of+Information+Systems&rft.issn=09050167&rft_id=info:doi/","Open source software; governance; FOSS; Computers; Free software; open-source software; software ecosystem; Public domain; ecosystem health; Misalignment; orchestration; Players; public sector; Public sector; Qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace.

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-25 16:56:34","2025-04-25 16:56:34","","361","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","2783221355","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Resilience+in+the+Open+Source+Software+Community%3A+How+Pandemic+and+Unemployment+Shocks+Influence+Contributions+to+Others%27+and+One%27s+Own+Projects&rft.au=Malgonde%2C+Onkar+S%3BSaldanha%2C+Terence+J+V%3BMithas%2C+Sunil.&rft.aulast=Malgonde&rft.aufirst=Onkar&rft.date=2023-03-01&rft.volume=47&rft.issue=1&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2022%2F17256","Open source software; COVID-19; Computers; Resilience; Pandemics; Public health; Community; Open source; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Nature conservation; Resource conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon.

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers’ early careers and hence shed light on future research in this direction.","2023","2025-04-25 16:56:35","2025-04-25 16:56:35","","529-548","","2","49","","","","","","","","","","English","","","ABI/INFORM Global","2776777604","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Off+to+a+Good+Start%3A+Dynamic+Contribution+Patterns+and+Technical+Success+in+an+OSS+Newcomer%26rsquo%3Bs+Early+Career&rft.au=Yang%2C+Yue%3BWang%2C+Yi%3BRedmiles%2C+David.&rft.aulast=Yang&rft.aufirst=Yue&rft.date=2023-01-01&rft.volume=49&rft.issue=2&rft.spage=529&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2022.3156071","Careers; open source; Task analysis; Ecosystems; Success; Documentation; Engineering profession; Codes; Correlation; Newcomer; Focusing; Statistical analysis; Computers--Software; Empirical analysis; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to analyse the teachers’ motivation to contribute to OSS projects for teaching. A structural equation model (SEM) has been defined under the postulates of the Path-Goal leadership theory and Motivational Behaviour. This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader. Second, this study finds that motivating the participants of a project – teachers in this case – is highly recommended, in order to reach a successful adoption of OSS solutions for education.","2022-12","2025-04-25 16:56:35","2025-04-25 16:56:35","","1449-1463","","12","34","","","","","","","","","","English","","","ABI/INFORM Global","2731285764","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Analysis+%26+Strategic+Management&rft.atitle=The+impact+of+leadership+styles+and+motivations%3A+lessons+from+Open+Source+Software+projects+for+educational+organizations&rft.au=Racero%2C+F+Jos%C3%A9%3BBueno%2C+Salvador%3BGallego%2C+M+Dolores.&rft.aulast=Racero&rft.aufirst=F&rft.date=2022-12-01&rft.volume=34&rft.issue=12&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Technology+Analysis+%26+Strategic+Management&rft.issn=09537325&rft_id=info:doi/10.1080%2F09537325.2021.1963698","Open source software; Leadership; Motivation; motivations; Software; Open-source software; Intrinsic motivation; Open Source Software; Context; leadership; Education; teachers; Public domain; Leadership style; Multivariate statistical analysis; Structural equation modeling; Teachers; Teaching; Technology: Comprehensive Works; Transactional leadership; Transformational leadership","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust→CCBs and the CCBs→Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust→CCBs relationship. These findings are explained from several theoretical perspectives, which provide directions for future research and help community management to maintain sustained participation.","2022-09","2025-04-25 16:56:35","2025-04-25 16:56:35","","907-920","","5","62","","","","","","","","","","English","","","ABI/INFORM Global","2708632042","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Sustained+Participation+in+Open+Source+Software+Project+Communities&rft.au=Shi%2C+Zhengzhong%3BSun%2C+Hua.&rft.aulast=Shi&rft.aufirst=Zhengzhong&rft.date=2022-09-01&rft.volume=62&rft.issue=5&rft.spage=907&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2021.1949645","Open source software; Computers; Data analysis; Open source; Participation; Hypotheses; OSS; Software; diffusion of innovation; Trust; Public domain; Software project management; Qualitative analysis; Community participation; integrative model of trust; intellectual capital creation; social learning system; stage model; sustained participation; vector autoregressive model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022-01","2025-04-25 16:56:35","2025-04-25 16:56:35","","165-195","","1","23","","","","","","","","","","English","","","ABI/INFORM Global","2619733915","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/Ydh4M?_a=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&_s=zHoOSQHC7zGSY1Lrj1y6C2ajqNs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=A+Motivation-Hygiene+Model+of+Open+Source+Software+Code+Contribution+and+Growth&rft.au=Sharma%2C+Pratyush+Nidhi%3BDaniel%2C+Sherae+L%3BTingting+%28Rachel%29+Chung%3BGrover%2C+Varun.&rft.aulast=Sharma&rft.aufirst=Pratyush&rft.date=2022-01-01&rft.volume=23&rft.issue=1&rft.spage=165&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00712","Open source software; Motivation; Information systems; Growth; Open source; Software; Open-source software; Computers--Information Science And Information Theory; Public domain; Source code; Growth models; A Motivation-Hygiene Model of Open Source Software Code Contribution and Growth; Computer program; Hygiene","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the differential impacts of such social influence on developers' initial and sustained participation behaviors were largely overlooked in previous research. We empirically studied the impacts of two social influence mechanisms—word‐of‐mouth (WOM) and observational learning (OL)—on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.","2021-09","2025-04-25 16:56:35","2025-04-25 16:56:35","","1133-1147","","9","72","","","","","","","","","","English","","","ABI/INFORM Global","2558095618","","","Place: Hoboken Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Science+and+Technology&rft.atitle=Differential+impacts+of+social+influence+on+initial+and+sustained+participation+in+open+source+software+projects&rft.au=Yang%2C+Xuan%3BLi%2C+Xiao%3BHu%2C+Daning%3BWang%2C+Harry+Jiannan.&rft.aulast=Yang&rft.aufirst=Xuan&rft.date=2021-09-01&rft.volume=72&rft.issue=9&rft.spage=1133&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Science+and+Technology&rft.issn=23301635&rft_id=info:doi/10.1002%2Fasi.24481","Open source software; Learning; Platforms; Library And Information Sciences; Social research; Open source; Software; Open-source software; Social influence; Social Influences; Social networks; Software development; Public domain; Software Projects; Software development tools; Modeling (Psychology); Observational Learning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 16:56:35","2025-04-25 16:56:35","","8","","","49","","","","","","","","","","English","","","ABI/INFORM Global","2582094786","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/x0MyK?_a=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&_s=%2FlTTM3bDFac2N1veyo77qKjQ6No%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Episodic+Peripheral+Contributors+and+Technical+Dependencies+in+Open+Source+Software+%28OSS%29+Ecosystems&rft.au=Moon%2C+Eunyoung.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2021-01-01&rft.volume=49&rft.issue=&rft.spage=8&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04908","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been institutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous security in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed security controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption enables businesses to deliver time-to-market security ready applications and services with accelerated velocity and sustainable agility in a cost-effective way.","2020-10","2025-04-25 16:56:35","2025-04-25 16:56:35","","1-28","","","97","","","","","","","","","","English","","","ABI/INFORM Global","2454359046","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Computers+%26+Security&rft.atitle=Modeling+continuous+security%3A+A+conceptual+model+for+automated+DevSecOps+using+open-source+software+over+cloud+%28ADOC%29&rft.au=Kumar%2C+Rakesh%3BGoyal%2C+Rinkaj.&rft.aulast=Kumar&rft.aufirst=Rakesh&rft.date=2020-10-01&rft.volume=97&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Computers+%26+Security&rft.issn=01674048&rft_id=info:doi/10.1016%2Fj.cose.2020.101967","Open source software; Cloud computing; Automation; Security; Business; Cybersecurity; Software development; Assurance; Public domain; Economic; Computers--Electronic Data Processing; Codification; Workflow; Applications programs; Business process; DevOps; Performance measurement; Security controls","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 16:56:35","2025-04-25 16:56:35","","1439","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2447305472","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Takeoff+of+Open+Source+Software%3A+A+Signaling+Perspective+Based+on+Community+Activities&rft.au=Setia%2C+Pankaj%3BBayus%2C+Barry+L%3BRajagopalan%2C+Balaji.&rft.aulast=Setia&rft.aufirst=Pankaj&rft.date=2020-09-01&rft.volume=44&rft.issue=3&rft.spage=1439&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F12576","Open source software; Computers; Open source; Software; Open-source software; Signaling; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for‐profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 16:56:35","2025-04-25 16:56:35","","369-402","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2352536913","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+Third+Design+Space%3A+A+postcolonial+perspective+on+corporate+engagement+with+open+source+software+communities&rft.au=Kendall%2C+Kenneth+E%3BKendall%2C+Julie+E%3BGermonprez%2C+Matt%3BMathiassen%2C+Lars.&rft.aulast=Kendall&rft.aufirst=Kenneth&rft.date=2020-03-01&rft.volume=30&rft.issue=2&rft.spage=369&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12270","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Computers--Computer Systems; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 16:56:35","2025-04-25 16:56:35","","20","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2500501225","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/JGBVI?_a=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&_s=ZwMsI0CRPDfS%2Fx12%2Fam7rwPvXL8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Decision-making+Processes+in+Community-based+Free%2FLibre+Open+Source+Software-development+Teams+with+Internal+Governance%3A+An+Extension+to+Decision-making+Theory&rft.au=Eseryel%2C+U+Yeliz%3BKangning+Wei%3BCrowston%2C+Kevin.&rft.aulast=Eseryel&rft.aufirst=U&rft.date=2020-01-01&rft.volume=46&rft.issue=&rft.spage=20&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04620","Open source software; Decision making; Computers--Information Science And Information Theory; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 16:56:36","2025-04-25 16:56:36","","764","","3","30","","","","","","","","","","English","","","ABI/INFORM Global","2307721543","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Does+Superposition+Influence+the+Success+of+FLOSS+Projects%3F+An+Examination+of+Open-Source+Software+Development+by+Organizations+and+Individuals&rft.au=Medappa%2C+Poonacha+K%3BSrivastava%2C+Shirish+C.&rft.aulast=Medappa&rft.aufirst=Poonacha&rft.date=2019-09-01&rft.volume=30&rft.issue=3&rft.spage=764&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2018.0829","Open source software; Organizations; Motivation; Open source; Software engineering; Open-source software; Computer architecture; Ownership; Success; Computers--Information Science And Information Theory; Project management; Software development; Freeware; 51821:Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services; Modular design; Project Success; Superposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Then, the detection rate and remaining faults of previous release are considered in the modeling and analysis of reliability of the current release. The optimal version-update time is computed using multi-attribute utility theory for these software systems, considering the two main utility factors, namely, rapid release strategy and level of reliability.

It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches.

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS.

De plus, contrairement aux études précédentes, nos résultats révelent également que les interactions entre utilisateurs et développeurs ont un rôle plus important que les activités reliées á la résolution de bugs dans la réussite des projets. Cette recherche propose une nouvelle maniere de mesurer la popularité d'un projet OSS et offrant ainsi aux organisations une meilleure compréhension.","2017-10","2025-04-25 16:56:36","2025-04-25 16:56:36","","47-74,117","","3","22","","","","","","","","","","English","","","ABI/INFORM Global","1969517670","","","Place: Paris Publisher: Editions ESKA","","; ","https://media.proquest.com/media/hms/PFT/1/g3eZ3?_a=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&_s=TDPmpbTuX3nLSv9pl2dBP8w0%2F4M%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Syst%C3%A8mes+d%27Information+et+Management&rft.atitle=OSS+popularity%3A+Understanding+the+relationship+between+user-developer+interaction%2C+market+potential+and+development+stage&rft.au=Cheruy%2C+Cl%C3%A9mence%3BRobert%2C+Frank%3BBelbaly%2C+Nassim.&rft.aulast=Cheruy&rft.aufirst=Cl%C3%A9mence&rft.date=2017-10-01&rft.volume=22&rft.issue=3&rft.spage=47&rft.isbn=&rft.btitle=&rft.title=Syst%C3%A8mes+d%27Information+et+Management&rft.issn=12604984&rft_id=info:doi/","Open source software; Information systems; Business And Economics--Management; Hypotheses; Open-source software; Linux; Success; Social; Social networks; Software quality; Public domain; Freeware; Business metrics; Developer; Investigations; Management science; Market penetration; Market potential; Popularity; User services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume – suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017","2025-04-25 16:56:36","2025-04-25 16:56:36","","43-66","","2","29","","","","","","","","","","English","","","ABI/INFORM Global","2866855510","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/wC7YX?_a=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&_s=AH2MYk0kmnJKLtLEtVIDIizdS%2Bw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+and+End+User+Computing&rft.atitle=Developers%2C+Quality+Control+and+Download+Volume+in+Open+Source+Software+%28OSS%29+Projects&rft.au=Hill%2C+Geoffrey%3BDatta%2C+Pratim%3BCandice+Vander+Weerdt.&rft.aulast=Hill&rft.aufirst=Geoffrey&rft.date=2017-04-01&rft.volume=29&rft.issue=2&rft.spage=43&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+and+End+User+Computing&rft.issn=15462234&rft_id=info:doi/10.4018%2FJOEUC.2017040103","Open source software; Open source; Software; Open-source software; Open Source Software; Quality control; Segmented Regression; Software development; Computers--Electronic Data Processing; Developer Limit; Downloading; Quality Control; Quality Control Index; Regression Discontinuity; Tragedy of the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While a large body of studies focuses on the importance of developers' reputations in their participation motivations, there is still lack of understanding for two issues. First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

In this research, we advance on such studies through an integrated FLOSS evaluation-selection model with a risk-based decision-making approach. Our model was built upon the other two literatures, and it was structured as a multi-attribute decision-making (MADM) model which contains 12 variables grouped in four risk categories: financial, organisational, end user, and technical ones. We illustrated its utilisation in the domain of information technology service management (ITSM) FLOSS tools.

Passive users play a critical role in the adoption and diffusion of OSS, and we need more research to understand their behaviors and motivations. We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.","2015-08","2025-04-25 16:56:36","2025-04-25 16:56:36","","674-706","","8","16","","","","","","","","","","English","","","ABI/INFORM Global","1711618000","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/OBJ/QFcWV?_a=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%3D%3D&_s=NukQhHdoSs7AKmjonN2p29jHjz0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Loyalty%2C+Ideology%2C+and+Identification%3A+An+Empirical+Study+of+the+Attitudes+and+Behaviors+of+Passive+Users+of+Open+Source+Software&rft.au=Choi%2C+Namjoo%3BChengalur-Smith%2C+Indushobha%3BNevo%2C+Saggi.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-08-01&rft.volume=16&rft.issue=8&rft.spage=674&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Sociology; Identification; Information systems; Community; Studies; User behavior; Marketing; Virtual communities; Open source; Hypotheses; Open-source software; Consumer behavior; Research; Success; Computers--Information Science And Information Theory; Software development; Loyalty; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; 7100:Market research; Consciousness; Ideology; Usability testing; User","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project’s time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project’s progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 16:56:37","2025-04-25 16:56:37","","116","","1","32","","","","","","","","","","English","","","ABI/INFORM Global","1697517813","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+Information+Systems&rft.atitle=Exploitation+and+Exploration+Networks+in+Open+Source+Software+Development%3A+An+Artifact-Level+Analysis%3A+JMIS&rft.au=Temizkan%2C+Orcun%3BKumar%2C+Ram+L.&rft.aulast=Temizkan&rft.aufirst=Orcun&rft.date=2015-07-01&rft.volume=32&rft.issue=1&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+Information+Systems&rft.issn=07421222&rft_id=info:doi/","Open source software; Political Science; Studies; Open source; Software engineering; Software; Open-source software; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 16:56:37","2025-04-25 16:56:37","","119-139","","1","39","","","","","","","","","","English","","","ABI/INFORM Global","1655249846","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/Q0uKV?_a=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&_s=c3Lp6TqythFY%2BWrN%2BTvJkpa1pVs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=Raising+the+general+public%27s+awareness+and+adoption+of+open+source+software+through+social+Q%26amp%3BA+interactions&rft.au=Choi%2C+Namjoo%3BYi%2C+Kwan.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-01-01&rft.volume=39&rft.issue=1&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/","Open source software; Motivation; Qualitative research; Studies; Computers--Internet; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1,409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. They also reproduced the results on new data provided by Mozilla. The authors constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-25 16:56:37","2025-04-25 16:56:37","","127-143","","2","39","","","","","","","","","","English","","","ABI/INFORM Global","1929783648","","","Place: Ahmedabad Publisher: Sage Publications, New Delhi India","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Vikalpa&rft.atitle=The+Emergence+of+an+Organizational+Field%3A+The+Case+of+Open+Source+Software&rft.au=Ojha%2C+Abhoy+K%3BRao%2C+Ravi+Anand.&rft.aulast=Ojha&rft.aufirst=Abhoy&rft.date=2014-04-01&rft.volume=39&rft.issue=2&rft.spage=127&rft.isbn=&rft.btitle=&rft.title=Vikalpa&rft.issn=02560909&rft_id=info:doi/10.1177%2F0256090920140211","Open source software; Business And Economics--Management; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them. Several implications for research and practice, and directions for future research are provided.","2014","2025-04-25 16:56:37","2025-04-25 16:56:37","","260-275","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","1660948775","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/bsfLV?_a=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&_s=zrtihhrjnuKV9%2BUVmos5%2B4c%2Bllg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+application+profiles+and+development+characteristics+of+library+Open+Source+Software+projects&rft.au=Choi%2C+Namjoo.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2014-04-01&rft.volume=32&rft.issue=2&rft.spage=260&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2FLHT-09-2013-0127","Open source software; Community; Research methodology; Studies; Open source; Libraries; Open-source software; Licenses; Success; Data collection; Software development; Programming languages; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; Library And Information Sciences--Computer Applications; 51921:Libraries and Archives; Academic libraries; Institutional repositories; Archival description; Datasets; Integrated library systems--ILS; Integrated library systems-ILS; Internet resources","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 16:56:37","2025-04-25 16:56:37","","477-512","","4","34","","","","","","","","","","English","","","ABI/INFORM Global","1510748443","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/7E55V?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yPWuXs0jr4o83q1fDVJWcSjQgII%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=International+Journal+of+Operations+%26+Production+Management&rft.atitle=Risk+of+adopting+mission-critical+OSS+applications%3A+an+interpretive+case+study&rft.au=Poba-Nzaou%2C+Placide%3BRaymond%2C+Louis%3BFabi%2C+Bruno.&rft.aulast=Poba-Nzaou&rft.aufirst=Placide&rft.date=2014-04-01&rft.volume=34&rft.issue=4&rft.spage=477&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Operations+%26+Production+Management&rft.issn=01443577&rft_id=info:doi/10.1108%2FIJOPM-03-2012-0117","Open source software; Information technology; Business And Economics--Management; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

We hypothesize that when an IPR enforcement action is filed, user interest and developer activity will be negatively affected in two types of related OSS projects - those that display technology overlap with the OSS application in dispute and business projects that are specific to the disputed OSS platform. We examine two widely publicized lawsuits-SCO v. IBM and FireStar/DataTern v. Red Hat-using data from SourceForge.net. Our difference-in-difference estimates show that in the months following the filing of SCO v. IBM, OSS projects that exhibit high technology overlap with the disputed OSS experienced a 15% greater decline in user interest and 45% less developer activity than projects in the control group; OSS projects that are intended for business and specific to the disputed OSS platform had a 34% greater decline in user interest and 86% less developer activity than the control group. We find similar results following the filing of FireStar/DataTern v. Red Hat. Our results are also robust to a variety of robustness checks, including a falsification exercise and subsample analyses.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated 'copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the 'new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11","2025-04-25 16:56:38","2025-04-25 16:56:38","","597-625","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2089824849","","","Place: Abingdon Publisher: Taylor & Francis LLC","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Free software; Property; Capitalism; Economic theory; Free and open-source software; Profitability; Profits; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One reason for this is project stagnation after developers quit their projects. This fact has motivated researchers to examine the factors that influence developers' intention to continue their participation. One factor is trust among developers. The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey. Our findings indicate that cooperative norms and effective communication engender trust, whereas an accreditation mechanism eliminates distrust. Additionally, trust positively influences their intention to continue participating, whereas distrust negatively influences it.

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Our primary interest was to conduct a study that was closely representative of the population of open source software projects in the world, rather than focus on the more-often studied, high-profile successful cases. After building a large database of projects (n=174,333) and implementing a major survey of open source developers (n=1403), we were able to conduct statistical analyses to investigate over forty theoretically-based testable hypotheses. Our data firmly support what we call the conventional theory of open source software, showing that projects start small, and, in successful cases, grow slightly larger in terms of team size. We describe the ""virtuous circle"" supporting conventional wisdom of open source collaboration that comes out of this analysis, and we discuss two other interesting findings related to developer motivations and how team members find each other. Each of these findings is related to the sustainability of these projects.","2013-01","2025-04-25 16:56:38","2025-04-25 16:56:38","","13-19","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473072","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/r92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=w1JsQafjriUDvJXmxD%2Fvc6puLsw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=Sustainability+in+Open+Source+Software+Commons%3A+Lessons+Learned+from+an+Empirical+Study+of+SourceForge+Projects&rft.au=Schweik%2C+Charles+M.&rft.aulast=Schweik&rft.aufirst=Charles&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=13&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; institutional analysis; Collective action; Business And Economics; Collaboration; Open source; open source software; Hypotheses; Open-source software; Research; Success; commons; Sustainable development; Sustainability; Public domain; Software Projects; Programmers; Books; Variables; Information commons; internet-based collaboration; SourceForge","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 16:56:38","2025-04-25 16:56:38","","32-39","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473053","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/y42HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=2t9cyrsjrGTKotUlU5ETuqoVg%2F4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=The+Evolving+Role+of+Open+Source+Software+in+Medicine+and+Health+Services&rft.au=Ingram%2C+David%3BSevket+Seref+Arikan.&rft.aulast=Ingram&rft.aufirst=David&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Research & development--R&D; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 16:56:38","2025-04-25 16:56:38","","28-36","","12","2","","","","","","","","","","English","","","ABI/INFORM Global","1614473125","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/Z92HV?_a=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%2BgIBWYIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=GbZFrwogPCXpMB86F2AnR11z97U%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=An+Enterprise+Perspective+on+Customer+Value+Propositions+for+Open+Source+Software&rft.au=Shanker%2C+Aparna.&rft.aulast=Shanker&rft.aufirst=Aparna&rft.date=2012-12-01&rft.volume=2&rft.issue=12&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help ""transfer"" their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

Yet many unanswered questions exist regarding why certain FOSS projects succeed while others fail. Drawing on social capital theory and human agency theory, this study proposes that FOSS projects stand a better chance of success if they possess desirable social network capital and adopt effective strategies. It further argues that valuable social network capital and effective strategies produce greater returns together than they do alone. The results of an empirical analysis reveal significant positive interactions between social capital variables and human agency/strategy variables, highlighting the importance of complementarity between social network ties and strategies in shaping the outcome of FOSS projects.

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS.

By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.","2012-04","2025-04-25 16:56:39","2025-04-25 16:56:39","","920","","4","85","","","","","","","","","","English","","","ABI/INFORM Global","925777279","","","Place: New York Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Systems+and+Software&rft.atitle=Free+and+Open+Source+Software+versus+Internet+content+filtering+and+censorship%3A+A+case+study&rft.au=Shirazi%2C+Farid.&rft.aulast=Shirazi&rft.aufirst=Farid&rft.date=2012-04-01&rft.volume=85&rft.issue=4&rft.spage=920&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Systems+and+Software&rft.issn=01641212&rft_id=info:doi/","Open source software; Studies; Censorship; Open source; Software packages; Internet; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Computers--Software; Free and open-source software; Systems design; 9178:Middle East; Filtering software; Iran","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects evolve and transform over time; therefore success must be examined longitudinally over a period of time. In this research, we examine two measures of project success: project popularity and developer activity, of 283 OSS projects over a span of 3 years, in order to observe changes over time. A comprehensive research model of OSS success is developed which includes both extrinsic and intrinsic attributes. Results show that while many of the hypothesized relationships are supported, there were marked differences in some of the relationships at different points in time lending support to the notion that different factors need to be emphasized as the OSS project unfolds over time.

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 16:56:39","2025-04-25 16:56:39","","156-187","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1018105738","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/wxbVU?_a=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%3D%3D&_s=X0oQ4nOZDi9uA5E9tyFKZJTP08c%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Information+Technology+%26+People&rft.atitle=Adoption+of+free%2Flibre+open+source+software+in+public+organizations%3A+factors+of+impact&rft.au=Rossi%2C+Bruno%3BRusso%2C+Barbara%3BSucci%2C+Giancarlo.&rft.aulast=Rossi&rft.aufirst=Bruno&rft.date=2012-04-01&rft.volume=25&rft.issue=2&rft.spage=156&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593841211232677","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Technology; Case studies; Technology adoption; Migration; Adoption; Case study; 5240:Software & systems; Public domain; Innovations; Public sector; 9130:Experimental/theoretical; Open standards; Cost control; Business process re-engineering; Disruptive innovation; Environmental factor; Library And Information Sciences--Computer Applications; Software services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-25 16:56:40","2025-04-25 16:56:40","","","","2","17","","","","","","","","","","English","","","ABI/INFORM Global","2546081220","","","Place: Wollongong Publisher: Australasian Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/na1qJ?_a=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%3D%3D&_s=N0WDCOWv2H3E1ddURTiZTg8qVwo%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Australasian+Journal+of+Information+Systems&rft.atitle=Enablers+of+Open+Source+Software+adoption%3A+A+case+study+of+APS+organisations&rft.au=Gurusamy%2C+Kavitha%3BCampbell%2C+John.&rft.aulast=Gurusamy&rft.aufirst=Kavitha&rft.date=2012-01-01&rft.volume=17&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Australasian+Journal+of+Information+Systems&rft.issn=14498618&rft_id=info:doi/10.3127%2Fajis.v17i2.731","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Computers--Computer Systems; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

This phenomenon is also known as ""Inner Source"". While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Following an initial systematic literature review to generate seed category data constructs, the authors performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques.","2011-12","2025-04-25 16:56:40","2025-04-25 16:56:40","","1319","","12","53","","","","","","","","","","English","","","ABI/INFORM Global","894730546","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=A+comparative+study+of+challenges+in+integrating+Open+Source+Software+and+Inner+Source+Software&rft.au=Stol%2C+Klaas-Jan%3BBabar%2C+Muhammad+Ali%3BAvgeriou%2C+Paris%3BFitzgerald%2C+Brian.&rft.aulast=Stol&rft.aufirst=Klaas-Jan&rft.date=2011-12-01&rft.volume=53&rft.issue=12&rft.spage=1319&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Open source; Software engineering; Software; Open-source software; Software development; 5240:Software & systems; Public domain; Systems development; Computers--Data Base Management; 9130:Experimental/theoretical; Systems integration; Comparative studies; Inner source; System integration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ''joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

OSS development takes online community as its organizational form, and developers voluntarily work for the project. In the project execution process, control aligns individual behaviors toward the organizational goals via the Internet and becomes critical to the success of OSS projects. This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community. The study contributes to a better understanding of OSS project organizations and processes, and provides advice for OSS development.","2011","2025-04-25 16:56:41","2025-04-25 16:56:41","","26-42","","1","22","","","","","","","","","","English","","","ABI/INFORM Global","2954642973","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/FF6YX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=6d%2Bi6am9M1LDqVW0E%2Fp1TGT7Yvg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=A+Study+of+Open+Source+Software+Development+from+Control+Perspective&rft.au=Lin%2C+Zhangxi%3BXu%2C+Bo%3BXu%2C+Yan.&rft.aulast=Lin&rft.aufirst=Zhangxi&rft.date=2011-01-01&rft.volume=22&rft.issue=1&rft.spage=26&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2011010102","Open source software; Open source; Software Development; Software; Open-source software; Software development; Control; Open Source Software (OSS); Software industry; Computers--Data Base Management; Industrial development; Open; OSS Development; Outcome; Project Management; Self-control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Behind a successful oss project lies a community of actors, ranging from core developers to passive users, held together by a flexible governance structure and membership, leadership and contribution policies that align their interests. The motivation behind individuals participating in oss projects can be, among others, social, ideological, hedonistic, or signaling, while companies gain from their access to high-quality, innovative projects and an increase in their reputation and visibility. Nowadays many business models rely on oss as a product through the provision of associated services, or in coexistence with proprietary software, hardware, services, or licensing. The numerous oss licenses mainly differ on how they treat derived software: some contain provisions that maintain its availability in open source form while others allow more flexibility. Through its widespread adoption, oss is affecting the software industry, science, engineering, research, teaching, the developing countries, and the society at large through its ability to democratize technology and innovation.","2011","2025-04-25 16:56:41","2025-04-25 16:56:41","","187-347","","3-4","4","","","","","","","","","","English","","","ABI/INFORM Global","2695489045","","","Place: Hanover Publisher: Now Publishers Inc","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.atitle=Open+Source+Software%3A+A+Survey+from+10%2C000+Feet&rft.au=Androutsellis-Theotokis%2C+Stephanos%3BSpinellis%2C+Diomidis%3BKechagia%2C+Maria%3BGousios%2C+Georgios.&rft.aulast=Androutsellis-Theotokis&rft.aufirst=Stephanos&rft.date=2011-01-01&rft.volume=4&rft.issue=3-4&rft.spage=187&rft.isbn=&rft.btitle=&rft.title=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.issn=15719545&rft_id=info:doi/10.1561%2F0200000026","Open source software; Leadership; Information systems; Open source; Software engineering; Software license; Software; Open-source software; Psychology; Operations management; Computers--Information Science And Information Theory; Information management; Software development; Public domain; Freeware; Source code; Developing countries--LDCs; Software distribution; Proprietary software; Engineering education; Licensing (technology); Software licenses; Visibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

HFOSS also integrates two volunteer-rich communities that have much in common: the humanitarian community and the open source community.

Recently, the focus has shifted toward an examination of a newer construct -temporal dispersion (TD). The study of TD so far has been constrained mostly to conceptual work. This study furthers the understanding of TD through an empirical investigation of its relationship with open source software (OSS) team performance. In this paper, hypotheses are developed based on coordination theory, and analyses are performed using data collected from multiple archival sources comprising 100 OSS development teams. Results indicate that TD positively affects development speed and quality and that software complexity moderates the relation between TD and software quality. Theoretical and practical implications are discussed.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-25 16:56:42","2025-04-25 16:56:42","","656","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","196420145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Using+the+DEMO+methodology+for+modeling+open+source+software+development+processes&rft.au=Huysmans%2C+Philip%3BVen%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Huysmans&rft.aufirst=Philip&rft.date=2010-06-01&rft.volume=52&rft.issue=6&rft.spage=656&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Computers--Data Base Management; Ontology; Demo; Process modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and tribal knowledge that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 16:56:42","2025-04-25 16:56:42","","211-223","","2","28","","","","","","","","","","English","","","ABI/INFORM Global","521142269","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/qPQuT?_a=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&_s=R3D%2FTgQI5szaHaGdFb%2BVEn%2FrVUA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+economy+of+free+and+open+source+software+in+the+preservation+of+digital+artefacts&rft.au=Morrissey%2C+Sheila.&rft.aulast=Morrissey&rft.aufirst=Sheila&rft.date=2010-04-01&rft.volume=28&rft.issue=2&rft.spage=211&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2F07378831011047622","Open source software; Studies; Open source; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Library And Information Sciences--Computer Applications; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article, we examine change in cognitive complexity and its impacts on maintenance in the context of open source software (OSS). Relationships of the change in cognitive complexity with the change in the number of reported bugs, time taken to fix the bugs, and contributions from new developers are examined and are all found to be statistically significant. In addition, several control variables, such as software size, age, development status, and programmer skills are included in the analyses. The results have strong implications for OSS project administrators; they must continually measure software complexity and be actively involved in managing it in order to have successful and sustainable OSS products.

We test the hypothesis that skill variety of participants is associated with project performance. We also explore whether the level of modularization of project activities is correlated with performance. Our econometric estimations show that skill heterogeneity is associated with project survival and performance. However, the relationship between skill diversity and performance is non-monotonic. Design modularity is also positively associated with the performance of the project. Finally, the interaction between skill heterogeneity and modularity is negatively associated with performance.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.

While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

The main results are that if Norden-Rayleigh-based approaches are used, they need to be complemented in order to account for the addition of new features during a product life cycle, and that programmer-participation based effort models result in distinctly lower estimations of effort than those based on output metrics, such as lines of code.

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-25 16:56:43","2025-04-25 16:56:43","","449-462","","5","16","","","","","","","","","","English","","","ABI/INFORM Global","212365312","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/b6OaT?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDQwODE3MTAxNjg4ODoyODcwNTA%3D&_s=yiXUHeA3Bd5m9qlApbZJ63Be1aM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Management+%26+Computer+Security&rft.atitle=Evaluating+the+performance+of+open+source+software+projects+using+data+envelopment+analysis&rft.au=Wray%2C+Barry%3BMathieu%2C+Richard.&rft.aulast=Wray&rft.aufirst=Barry&rft.date=2008-10-20&rft.volume=16&rft.issue=5&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Information+Management+%26+Computer+Security&rft.issn=09685227&rft_id=info:doi/10.1108%2F09685220810920530","Open source software; Studies; Productivity; Business And Economics--Management; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-25 16:56:44","2025-04-25 16:56:44","","142-156","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","211770348","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aQ4UT?_a=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&_s=skz%2By9xiJklpExxCBn8Dys3vIXk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Innovation+Management&rft.atitle=Online+innovation%3A+the+case+of+open+source+software+development&rft.au=Vujovic%2C+Sladjana%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=Vujovic&rft.aufirst=Sladjana&rft.date=2008-01-01&rft.volume=11&rft.issue=1&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Innovation+Management&rft.issn=14601060&rft_id=info:doi/10.1108%2F14601060810845268","Open source software; Innovation; Communication; Information technology; Studies; Business And Economics--Management; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Public domain; Technological change; Innovations; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Following a case study methodology, we examined developer interaction data from three active and successful FLOSS projects using qualitative research methods, specifically inductive content analysis, to identify the task-assignment mechanisms used by the participants. We found that 'self-assignment' was the most common mechanism across three FLOSS projects. This mechanism is consistent with expectations for distributed and largely volunteer teams.

Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

Under what conditions can it be employed in other contexts? ""Collective invention"" regimes usually ended when a dominant design emerged. This is not the case with OSS. Firstly, the OSS community developed the institutional innovation of OSS licenses enabling OSS software to survive as a common property. Secondly, these licenses are mainly enforced by pro-socially motivated contributors. We characterize the conditions under which OSS communities develop and sustain pro-social commitments. We point out the vulnerability of these conditions to developments in patent legislation.

Little attention has been paid to individuals who spend valuable time in lists helping participants on some mundane yet vital project activities. Using three Debian lists as a case study we investigate the impact of knowledge brokers and their associated activities in open source projects. Social network analysis was used to visualize how participants are affiliated with the lists. The network topology reveals substantial community participation. The consequence of collaborating in mundane activities for the success of open source software projects is discussed. The direct beneficiaries of this research are in the identification of knowledge experts in open source software projects.

This survey-based study, conducted with 402 active LUG members representing 191 different LUGs from 23 countries and employing structural equation modeling methodology, supports the proposed model. Furthermore, we find that the Linux user's experience level moderates the extent of the LUG's social influence and its impact on the user's participation.

This paper develops and tests a model of the impacts of license restrictiveness and organizational sponsorship on two indicators of success: user interest in, and development activity on, open source software development projects. Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.

Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied - especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 16:56:45","2025-04-25 16:56:45","","227-238","","2","44","","","","","","","","","","English","","","ABI/INFORM Global","222420968","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/ORIG/5/G0cEE?_a=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&_s=SVgzekDe95rQdVHfJ2Zo%2BltJgw0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Systems+Journal&rft.atitle=The+value+of+open+standards+and+open-source+software+in+government+environments&rft.au=Simon%2C+K+D.&rft.aulast=Simon&rft.aufirst=K&rft.date=2005-04-01&rft.volume=44&rft.issue=2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=IBM+Systems+Journal&rft.issn=00188670&rft_id=info:doi/","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-25 16:56:45","2025-04-25 16:56:45","","","","2","48","","","","","","","","","","English","","","ABI/INFORM Global","237056523","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Open+source+software+for+medical+image+processing+and+visualization&rft.au=Yoo%2C+Terry+S%3BAckerman%2C+Michael+J.&rft.aulast=Yoo&rft.aufirst=Terry&rft.date=2005-02-01&rft.volume=48&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/10.1145%2F1042091.1042120","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Research & development--R&D; United States--US; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Computers--Data Communications And Data Transmission Systems; Digital image processing; Image; Medical imaging","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This observation, however, has not been discussed in much detail and critically addressed by the software engineering community. Most of the claims associated with open source appear to be weakly motivated and articulated. For this reason, this paper proposes some qualitative reflections and observations on the nature of open source software and on the most popular and important claims associated with the open source approach. The ultimate goal of the paper is to identify the concepts and intuitions that are really peculiar to open source, and to distinguish them from features and aspects that can be equally applied to or found in proprietary software.

This research investigates the evolution of open source software using a case study of the Samba project. Through the application of both qualitative and quantitative techniques, Samba's software development and evolution over a seven-year period are tracked and assessed. This assessment and the findings of similar, previously reported studies lead us to propose a general framework for the evolution and the key drivers of open source software evolution.

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-25 16:56:45","2025-04-25 16:56:45","","94-112","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","821692253","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/8v97U?_a=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&_s=pUsDcFs3MVZkPLVZxMuyqK90UPQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Open+source+software+and+software+patents%3A+A+constitutional+perspective&rft.au=Pfaffenberger%2C+Bryan.&rft.aulast=Pfaffenberger&rft.aufirst=Bryan&rft.date=1999-10-01&rft.volume=12&rft.issue=3&rft.spage=94&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-999-1029-x","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The analyses reveal that individuals from different backgrounds have distinct migration patterns. Individuals who grew up in rural areas but moved to cities have significantly different political preferences than individuals who grew up and still reside in rural areas. The results indicate that KD and SD mainly attract rural voters, while L, MP, M, and V primarily attract urban residents. Individuals with certain characteristics are likelier to choose specific types of residential areas and have political preferences typical for their area of choice. This suggests a geographical sorting of different groups into rural and urban areas and a geographic political divergence (in support of SD, KD) and convergence (in support of C, S, L, M) in party preferences.","2024","2025-04-25 16:57:34","2025-04-25 16:57:34","","1005","","5","126","","","","","","","","","","English","","","International Bibliography of the Social Sciences (IBSS); Sociological Abstracts; Worldwide Political Science Abstracts","3168416243","","","Place: Lund Publisher: Fahlbeckska Stiftelsen","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Statsvetenskaplig+Tidskrift&rft.atitle=Geografiska+r%26ouml%3Btter+och+politiska+vingar%3A+Hur+klass+och+omr%26aring%3Bden+formar+och+sorterar+oss+utifr%26aring%3Bn+politiska+preferenser&rft.au=Rickardsson%2C+Jonna%3BLund%C3%A5sen%2C+Susanne+Wallman.&rft.aulast=Rickardsson&rft.aufirst=Jonna&rft.date=2024-01-01&rft.volume=126&rft.issue=5&rft.spage=1005&rft.isbn=&rft.btitle=&rft.title=Statsvetenskaplig+Tidskrift&rft.issn=00390747&rft_id=info:doi/","Convergence; Social classes; Migration; Urban areas; Rural areas; Migration patterns; Political parties; Preferences; Residential areas; Rural communities; Urban population","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some questions are raised, such as: (1) To what extent do organizations linked with Collaborative Economy make use of Free and Open Source Software?, (2) What are the incentives that motivate the implementation of Free and Open Source Software in Collaborative Economy companies?, (3) What use do Collaborative Economy companies give to Free and Open Source Software?, and (4) Is there a greater use of Free and Open Source Software expected for the coming years among these organizations? To answer these questions, a study based on the Delphi method has been designed. To this end, a panel of 15 high-level experts in the field was formed.

In this study, we focus on open innovation processes among firms and radical circles and shed light on the related value capture mechanisms. We rely on a detailed qualitative case analysis of collaborations between firms and three radical circles (i.e., Slow Food, Memphis, and the Free Software Foundation). Our case studies highlight that the firms captured value from collaborating with these radical circles through developing internal assets (reputational, organizational, intellectual and human, and technological) and new business models. Starting from these insights, the study offers several contributions to open innovation research as well as interesting avenues for future inquiry into this topic.","2020-09","2025-04-25 16:57:35","2025-04-25 16:57:35","","1","","","158","","","","","","","","","","English","","","ABI/INFORM Global; Materials Science & Engineering Collection; Sociological Abstracts","2456877123","","","Place: New York Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technological+Forecasting+and+Social+Change&rft.atitle=Value+capture+in+open+innovation+processes+with+radical+circles%3A+A+qualitative+analysis+of+firms%27+collaborations+with+Slow+Food%2C+Memphis%2C+and+Free+Software+Foundation&rft.au=Dell%27Era%2C+Claudio%3BDi+Minin%2C+Alberto%3BFerrigno%2C+Giulio%3BFrattini%2C+Federico%3BLandoni%2C+Paolo%3BVerganti%2C+Roberto.&rft.aulast=Dell%27Era&rft.aufirst=Claudio&rft.date=2020-09-01&rft.volume=158&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Technological+Forecasting+and+Social+Change&rft.issn=00401625&rft_id=info:doi/10.1016%2Fj.techfore.2020.120128","Sociology; Innovation; Qualitative research; Collaboration; Software; Companies; Case studies; Business; Innovations; Open innovation; Qualitative analysis; Value capture; Food; Memphis; Slow Food","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors draw on a case study of the ‘Heidi bug’ discovered during the development of the Mozilla Firefox web browser to examine how ‘gendered talk’ was (en)‐acted to facilitate ‘bricolage’ in an online work environment. Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender‐balanced, women‐friendly and inclusive workplace certainly would benefit from a more diverse environment. This article highlights the gendered aspect of software development through examining the language use and mainstream ‘bricolage’ practice, and establishes a compelling ground for enlarging the talent pool to include more women and integrating gender ethics (e.g., raising awareness of sensitive language and design approaches) into computer ethics education.","2019-07","2025-04-25 16:57:35","2025-04-25 16:57:35","","1017-1031","","7","26","","","","","","","","","","English","","","ABI/INFORM Global; International Bibliography of the Social Sciences (IBSS); Sociological Abstracts","2257969279","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Gender%2C+Work+and+Organization&rft.atitle=Gendered+work+culture+in+free%2Flibre+open+source+software+development&rft.au=Yu%E2%80%90Wei+Lin%3Bden+Besten%2C+Matthijs.&rft.aulast=Yu%E2%80%90Wei+Lin&rft.aufirst=&rft.date=2019-07-01&rft.volume=26&rft.issue=7&rft.spage=1017&rft.isbn=&rft.btitle=&rft.title=Gender%2C+Work+and+Organization&rft.issn=09686673&rft_id=info:doi/10.1111%2Fgwao.12255","Open source software; Ethics; Qualitative research; Masculinity; Women; Business And Economics--Management; open innovation; Software; Feminism; Case studies; Internet; Software development; Case study; Public domain; Freeware; Property; Corporate culture; Free; Work environment; Consciousness; Computer ethics; Gender; Ability; Bricolage; Cultural change; free/libre open source software; gendered talks; Hegemony; heterohegemonic masculinity; Heterosexuality; humour; Ignorance; Language usage; Moral education; online virtual work space; Organizational culture; work cultures; Workplaces","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study proposes a theoretical framework, under the prism of which socio-economic, technological and institutional factors critical to eGovernment and OSS are revealed. The hypotheses are evaluated by means of an econometric model of simultaneous equations. In order to better gauge the results of the hypotheses, the model is evaluated over economic environments at different stages of development. Social development and OSS growth were found to be the most important facilitators for eGovernment maturity, across countries of all stages of development. Institutional quality, technological openness, freedom in press and the macro-economic environment exerted different weights of importance across different country groupings. Findings also suggest that technological infrastructure and innovation are important drivers for OSS growth across countries at all stages of development. Research results can provide useful input for research in eGov, as they open up new directions in the study of the relation with OSS.","2015-10","2025-04-25 16:57:35","2025-04-25 16:57:35","","132","","","99","","","","","","","","","","English","","","ABI/INFORM Global; Materials Science & Engineering Collection; Sociological Abstracts","1732841796","","","Place: New York Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technological+Forecasting+and+Social+Change&rft.atitle=Cross-national+analysis+of+the+relation+of+eGovernment+maturity+and+OSS+growth&rft.au=Lakka%2C+Spyridoula%3BStamati%2C+Teta%3BMichalakelis%2C+Christos%3BAnagnostopoulos%2C+Dimosthenis.&rft.aulast=Lakka&rft.aufirst=Spyridoula&rft.date=2015-10-01&rft.volume=99&rft.issue=&rft.spage=132&rft.isbn=&rft.btitle=&rft.title=Technological+Forecasting+and+Social+Change&rft.issn=00401625&rft_id=info:doi/10.1016%2Fj.techfore.2015.06.024","Open source software; Sociology; Socioeconomic factors; Studies; Hypotheses; Software; Open-source software; Econometrics; Economics; Electronic government; 5240:Software & systems; 9130:Experiment/theoretical treatment; Economic; Technological change; Freeware; Innovations; Research & development--R&D; E-government; Property; sociology of technology; 1772:sociology of science; 1130:Economic theory; 1220:Social trends & culture; Economic development; Freedoms; Economic models; Developmental stages; Economic factors; Maturity; Natural environment; Organizational aspects; Simultaneous equations; Social change; Social development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors ('problem solvers') tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs ('problems') tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between 'core' and 'peripheral' members identified exclusively on the basis of their individual level of contribution to the project.

Drawing an overly technical distinction between these two categories of labor potentially overlooks some important aspects of the processes of capitalist reproduction, particularly the increasingly social character of labor, and as such, a broader definition must be considered. The labor engaged in the production of Free and Open Source Software (FOSS) is illustrative of this need for further examination of the productive-unproductive distinction, for the fact that though FOSS, in some respects, appears tendentially anti-capitalist, in fact, it, and the immaterial labor driving it, has essentially been fully subsumed in the apparatus of capital accumulation.

The author theorizes Free Software as a new form of property that is infecting capitalism like a virus, challenging the system of private property central to its dominant logic. Free Software can be produced by developers working for free in peer communities or in profit-oriented firms. The author explores the conditions under which Free Software is produced through peer versus market-based production, emphasizing the implications for constructing the Free Software market and the digital commons. The author identifies actors' motivations, the organizational structure of production, and financial resources as three factors shaping these conditions. The author focuses on the case of Ubuntu, a Free Software operating system that is available free of charge on the Internet. Ubuntu is produced by Canonical, a Free Software, market-based firm, through an intriguing combination of market-based and peer production that both embodies and transforms capitalist practices.

This approach is used to examine how F/OSS may contribute to a people-centred and development-oriented information society. Three questions are asked: (1) Is it helpful to view F/OSS as market or non-market production? (2) How is F/OSS distributed and marketed? (3) How does F/OSS rely on gendered labour? By analysing existing writings on F/OSS, it is concluded that market production should not be privileged over other modes of production; state intervention is required to ensure an equitable distribution of F/OSS; and gendered labour needs to be made visible in the F/OSS production.

It draws on a study of online observation of a virtual community, i.e. an open source software (OSS) community. The paper examines general and specific advantages and disadvantages of the observer roles in online settings by relating these roles to the same roles assumed in offline settings. The study suggests that under the right circumstances online and offline observation may benefit from being combined as they complement each other well. Quality issues and factors important to elicit trustworthy observational data from online study settings, such as OSS communities, are discussed. A proposition is made concerning how threats to credibility and transferability in relation to online observation (i.e. lack of richness and detail, risk of misunderstandings) can be diminished, while maintaining the level of dependability (which is potentially high due to a greater degree of anonymity and ""isolation"" in online settings). The paper thus suggests that the less participative the researcher's online observer role is, the more s/he should consider introducing offline data collection techniques rather than adopting a more participative role in the observed online setting. This methodological discussion forms the basis for making a well-considered choice of online observer role rather than passively sliding into a role assigned by the setting.

It draws on a study of online observation of a virtual community, i.e. an open source software (OSS) community. The paper examines general and specific advantages and disadvantages of the observer roles in online settings by relating these roles to the same roles assumed in offline settings. The study suggests that under the right circumstances online and offline observation may benefit from being combined as they complement each other well. Quality issues and factors important to elicit trustworthy observational data from online study settings, such as OSS communities, are discussed. A proposition is made concerning how threats to credibility and transferability in relation to online observation (i.e. lack of richness and detail, risk of misunderstandings) can be diminished, while maintaining the level of dependability (which is potentially high due to a greater degree of anonymity and 'isolation' in online settings). The paper thus suggests that the less participative the researcher's online observer role is, the more s/he should consider introducing offline data collection techniques rather than adopting a more participative role in the observed online setting. This methodological discussion forms the basis for making a well-considered choice of online observer role rather than passively sliding into a role assigned by the setting.

This approach is used to examine how F/OSS may contribute to a people-centred and development-oriented information society. Three questions are asked: (1) Is it helpful to view F/OSS as market or non-market production? (2) How is F/OSS distributed and marketed? (3) How does F/OSS rely on gendered labour? By analysing existing writings on F/OSS, it is concluded that market production should not be privileged over other modes of production; state intervention is required to ensure an equitable distribution of F/OSS; and gendered labour needs to be made visible in the F/OSS production.

I highlight how developers concurrently tinker with technology and the law using similar skills, which transform and consolidate ethical precepts among developers. I contrast this legal pedagogy with more extraordinary legal battles over intellectual property, speech, and software. I concentrate on the arrests of two programmers, Jon Johansen and Dmitry Sklyarov, and on the protests they provoked, which unfolded between 1999 and 2003. These events are analytically significant because they dramatized and thus made visible tacit social processes. They publicized the challenge that F/OSS represents to the dominant regime of intellectual property (and clarified the democratic stakes involved) and also stabilized a rival liberal legal regime intimately connecting source code to speech.

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making 'good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.

While some technologies are inherently political, other technologies become politicized through competition among different groups and organizations. How do seemingly apolitical technologies become politicized? In this article, the author examines the case of the ""circuit riders,"" a progressive technology movement in the United States that promotes information technology use among nonprofit and grassroots organizations, to show how a particular technology is politicized through field-level interactions. Applying and contributing to actor-network theory, the author finds that translation takes place as an organizational process by which actors associate the ideals of the technology in question with their political ideals and then attempt to enroll other actors to accept the resultant associations. Successful association depends on both discursive and organizational practices.

We begin by measuring the digital divide in these very different regions of the world. Our research demonstrates, both quantitatively and qualitatively, how the digital divide places populations in both regions at a disadvantage.

It focuses on a unique facet of this struggle, rooted in the centrality of information technologies for global trade and production, as well as new forms of media and digital culture. The analysis has four main parts: examining the key role of software as a technological infrastructure for diverse forms of globalization; conceptualizing the contradictory implications of three software business models for realizing the utopian potential of digital technology to develop forms of globalization from below; exploring how three free and open source software business models were put into practice by Red Hat, IBM and the Free Software Foundation; and analysing Brazilian software policy as a form of globalization from below that challenges the historical dominance of the global North and seeks to develop new forms of digital inclusion and digital culture.

Such movements for the political use and regulation of FLOSS mark a distinct turn in the objectives and work of FLOSS advocates, whose activities largely focused on the dissemination of FLOSS as a technological artifact. This paper investigates the network of diverse actors involved in promoting FLOSS legislation in Peru, one of the first nations where a movement for FLOSS legislation emerged. It emphasizes that crucial to the work of FLOSS' network actors is not their merely technological productivity, but their cultural and political productivity - that is, their ability to produce diverse body of meaning made both evident and mobile in narratives of FLOSS use and adoption.

The internal heterogeneity of project contributors questions the functioning of collective action: how can commitments that are so dissimilar be put together? Our objective is to consider FLOSS communities as going concerns which necessitate a minimum of order and common, shared, social rules to function. Through an in-depth and diachronic analysis of the Spip project, we present two classical modes of social regulation: a control regulation centred on the product and an autonomous regulation reflecting the differentiated commitments. Our data shows that the meaning, value and legitimacy of contributors' involvements are defined and rated more collectively, through exchanges, judgments, and evaluations. A third regulation mode, called distributed community regulation and aimed at creating and transforming shared rules that produces recognition and stratification, is then presented.

In common with many other FLOSS projects, the DBE project focused on the development of infrastructural software components. Infrastructures and FLOSS software exhibit multiplicity: as objects they both change and stay the same. Whilst the implications of multiplicity with respect to infrastructure have been well-documented, with respect to FLOSS, they remain under-explored. Through examining how the DBE engaged new participants we were able to explore the nature of the FLOSS software object by asking the implied question: engagement with what? We draw on recent analysis by Law and Singleton to show how the innovative yet non-existent potentiality of the DBE was as significant to engagement as its steadily growing codebase. We argue that acknowledging the materiality and immateriality of the FLOSS software object has important consequences for management of, and engagement with, FLOSS projects.

However, the current strategies deployed by law enforcement to combat cybercrime have proven ineffective. Borne out of traditional notions of criminal behavior, these strategies and tactics are often ill-suited to prevent or punish cybercrime, which often defies the traditional notions of criminal behavior bounded by the corporeal world such as scale and proximity. This Comment argues that a more effective methodology in the fight against cybercrime is to develop a model of community policing, in which the power to deter and prevent cybercrime is divested into the hands of individual computer users. One such strategy for achieving effective community policing against cybercrime is through the increased use of open-source software, software in which users are given access to the underlying source code and may make modifications to that source code in order to ameliorate vulnerabilities that may enable cybercrime. This Comment looks at the development of traditional community policing strategies and argues that the increased use of open source software-spurned by greater involvement by government and corporations-may be a more effective technique in the fight against cybercrime.

Governance is distributed, rather than centralized, so it is not clear where responsibility lies. This fact may help current powers increase their power rather than creating a more democratic system. This paper discusses ideas about the concept of Empire within the context of the information society, showing how distributive governance is used to maintain power rather than increase democracy.

Open source denotes a cooperative & voluntary mode of software development cross-cutting organizational boundaries & transcending relations of market exchange. Starting with the Open Systems Movement in the late 1970s, which was driven by business strategic & industrial policy interests & complemented by a spirit of mutual support in professional communities, a social movement type of collective action has emerged which develops knowledge as a public good.

We argue that while rightly stressing human agency they also create a false dichotomy between agential and environmental factors in the explanation. Felin and Foss create further confusion by hinting - without adequate clarification - at an untenable notion of human agency as an uncaused cause. We raise several questions of clarification for these authors.

However, there has been little focus on developing valid frameworks that enable critical evaluation and common understanding of factors influencing OSS adoption. This paper seeks to address this shortcoming by presenting a theory-grounded framework for exploring these factors and explaining their influence on OSS adoption, with the context of study being small- to medium-sized Information Technology (IT) businesses in the U.K. The framework has implications for this type of business - and, we will suggest, more widely - as a frame of reference for understanding, and as tool for evaluating benefits and challenges in, OSS adoption. It also offers researchers a structured way of investigating adoption issues and a base from which to develop models of OSS adoption. The study reported in this paper used the Decomposed Theory of Planned Behaviour (DTPB) as a basis for the research propositions, with the aim of: (i) developing a framework of empirical factors that influence OSS adoption; and (ii) appraising it through case study evaluation with 10 U.K. Small- to medium-sized enterprises in the IT sector. The demonstration of the capabilities of the framework suggests that it is able to provide a reliable explanation of the complex and subjective factors that influence attitudes, subjective norms and control over the use of OSS. The paper further argues that the DTPB proved useful in this research area and that it can provide a variety of situation-specific insights related to factors that influence the adoption of OSS.

This paper proposes the adoption of relevant Free/Libre/Open Source Software (FLOSS) practices in order to improve software development projects in industry. Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.

An expanded version of Gallivan's (2001) framework of contingent authority innovation describes the way new policies extended through the public structure of the country. Findings indicate that Venezuela's FLOSS migration process fuses the agendas of social inclusion, sovereignty, and freedom that the government is pursuing with the availability of a ""Free Libre"" technology. The present project specifically contributes to the literature that examines information and communication technology policies and their impact on developing countries. In addition, the theoretical expansion of Gallivan's framework can apply to other governmental technological adoptions where ideology and politics play critical roles.

Since software development is a creative task, the motivation of open source programmers can be compared to individuals in creative industries (Caves 2002). This paper summarizes the important trends in the research on motivation in open source and identifies variables that should be included in future research. Specifically, the current literature favors a taxonomy that considers two components of motivation--intrinsic (e.g., fun, flow, learning, community) and extrinsic (e.g., financial rewards, improving future job prospects, signaling quality). I make a case for incorporating both elements in developing an integrative theory about developer motivation. Three elements are identified as being unique to FLOSS development-diversity of project structures, co-existence of companies and communities and co-existence of creative and commercial elements. The important empirical evidence on FLOSS developer motivation is presented and analyzed. Four factors are identified as important mitigating and moderating factors in the conversation surrounding developer motivation- financial incentives, nature of task, group size and group structure. The role of these factors on developer motivation is discussed.[PUBLICATION ABSTRACT]","2006","2025-04-25 16:59:08","2025-04-25 16:59:08","","17-39","","4","18","","","","","","","","","","English","","","ABI/INFORM Global","840525397","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/rr87U?_a=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%3D%3D&_s=L%2FVcdfGFikGd87pIWhrmzIOnvy0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=On+the+intrinsic+and+extrinsic+motivation+of+free%2Flibre%2Fopen+source+%28FLOSS%29+developers&rft.au=Krishnamurthy%2C+Sandeep.&rft.aulast=Krishnamurthy&rft.aufirst=Sandeep&rft.date=2006-01-01&rft.volume=18&rft.issue=4&rft.spage=17&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-006-1002-x","Open source software; Sociology; Motivation; Open source; Open-source software; Software development; Developer; Creative industries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I suggest that the support for non-proprietary software (collectively FLOSS) allows developing countries to comply with their multi-lateral commitments and support the potential development of local software development. Because of the General Public License's dependence on copyright law, the deployment of FLOSS allows compliance with the Trade Related Aspects of Intellectual Property Rights (TRIPs) agreement, while at the same time facilitating the development of a local software 'community'.

One could argue that Free Software Foundation is using copyright to enforce their free software licenses as aggressively as the Business Software Alliance is enforcing its clients' copyrights. We will show that the reality is more complex and that there is a significant difference: the free software community uses primarily non-legal enforcement methods and trusts on social norms. We argue that free software could be used as a tool to make copyright more accepted in the less developed world because of its positive connection with copyright and community based approach. We explain why strong copyright is also in the interest of free software developers.

If the context in which free and open source software tools are created and employed is examined, it becomes clear that: the sustainability of any software (FOSS, custom or commercial) to ensure the preservation of the digital heritage will depend on careful assessment of, and provision for, the costs (implicit and explicit) entailed in the production and continued employment of these tools. The purpose of this paper is to focus on FOSS and archiving of the digital heritage. Portico, a not-for-profit digital preservation service, explores the costs of FOSS based on its experiences as a working archive with an extremely long time horizon. There are considerable benefits to FOSS, including its openness and the broad-based testing of it in real-world situations. FOSS tools can provide considerable cost savings over proprietary tools. However, FOSS is neither free to use, nor to create, nor to maintain. Digital preservation organizations must inventory not only the FOSS tools in the preservation arsenal, but the network of sustaining tools (FOSS and otherwise), documentation, and tribal knowledge that make these tools effectively usable. The risks to sustainability of this network of resources must be assessed, and determine what it will cost to keep them viable. Strategies will have to be considered and implemented for providing the means to sustain these resources. An engaged community of use is the best guarantor of the vitality of any FOSS tool. As that community wanes, it becomes even more essential to capture the significant properties and domain knowledge about that tool. Creators of new software in the digital preservation space have a particular obligation to provide and maintain information about the significant properties of that software. The paper shows how Portico brings its practical experiences integrating multiple FOSS tools to bear on an analysis of the costs to creating and maintaining these tools over the long-term.","2010","2025-04-25 16:59:09","2025-04-25 16:59:09","","211-223","","2","28","","","","","","","","","","English","","","ABI/INFORM Global","521142269","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/qPQuT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzODA3NjIJNTIxMTQyMjY5Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTAvMDQvMDFyCjIwMTAvMDYvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=NwdJ61IfH0rCBSU3j8JRJOfAADI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+economy+of+free+and+open+source+software+in+the+preservation+of+digital+artefacts&rft.au=Morrissey%2C+Sheila.&rft.aulast=Morrissey&rft.aufirst=Sheila&rft.date=2010-04-01&rft.volume=28&rft.issue=2&rft.spage=211&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2F07378831011047622","Open source software; Studies; Open source; Linux; Software utilities; Sustainability; Costs; Public domain; 9130:Experimental/theoretical; Free and open-source software; Library And Information Sciences--Computer Applications; Nonprofit organizations; 51921:Libraries and Archives; 5200:Communications & information management; Artifact; Corporate sponsorship; Cost; Digital heritage; Digital libraries; Digital preservation; Externality; Historic artifacts; Preservation; Sustainable design","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, this expansion has also brought significant security challenges, particularly introducing and propagating software vulnerabilities. Despite the use of machine learning and formal methods to tackle these issues, there remains a notable gap in comprehensive surveys that summarize and analyze both Vulnerability Detection (VD) and Security Patch Detection (SPD) in OSS. This article seeks to bridge this gap through an extensive survey that evaluates 127 technical studies published between 2014 and 2023, structured around the Vulnerability-Patch lifecycle. We begin by delineating the six critical events that constitute the Vulnerability-Patch lifecycle, leading to an in-depth exploration of the Vulnerability-Patch ecosystem. We then systematically review the databases commonly used in VD and SPD, and analyze their characteristics. Subsequently, we examine existing VD methods, focusing on traditional and deep learning based approaches. Additionally, we organize current security patch identification methods by kernel type and discuss techniques for detecting the presence of security patches. Based on our comprehensive review, we identify open research questions and propose future research directions that merit further exploration.","2025-01","2025-04-25 16:59:09","2025-04-25 16:59:09","","1","","1","57","","","","","","","","","","English","","","ABI/INFORM Global","3156169971","","","Place: Baltimore Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=ACM+Computing+Surveys&rft.atitle=Vulnerabilities+and+Security+Patches+Detection+in+OSS%3A+A+Survey&rft.au=Lin%2C+Ruyan%3BFu%2C+Yulong%3BYi%2C+Wei%3BYang%2C+Jincheng%3BCao%2C+Jin%3BDong%2C+Zhiqiang%3BXie%2C+Fei%3BLi%2C+Hui.&rft.aulast=Lin&rft.aufirst=Ruyan&rft.date=2025-01-01&rft.volume=57&rft.issue=1&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=ACM+Computing+Surveys&rft.issn=03600300&rft_id=info:doi/10.1145%2F3694782","Open source software; Computers; Software reliability; Deep learning; Security; Machine learning; Formal method; Identification methods; Vulnerability","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While these initiatives hold significant promise, they frequently encounter hurdles like poor productivity, leading to premature demise. This study explores activities that contribute to the long-term well-being of public-sector FOSS ecosystems, focusing on public-sector entities as orchestrators and keystone players. A qualitative multi-case study of three ecosystems was conducted, with data collected through interviews, participant observation, and analysis of online discussion forums. The study presents a model for health-sustaining activities in public-sector FOSS ecosystems. Orchestrators and keystone players are found to engage in health-sustaining activities through rulemaking, role creation, and tool provision, hinting at the explanatory potential of Activity Theory. Furthermore, the study identifies key challenges in orchestrating public sector FOSS ecosystems, such as institutional misalignment and conflicting policy frameworks, highlighting these as critical areas for future research.","2024","2025-04-25 16:59:09","2025-04-25 16:59:09","","","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","3152500844","","","Place: Aalborg Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/lP17b?_a=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%3D%3D&_s=puvyoHces6UrwrEs9hl2EOHFTb4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Scandinavian+Journal+of+Information+Systems&rft.atitle=Health+and+Orchestration+of+Public-Sector+Open-Source+Software+Ecosystems+Roles%2C+rules+and+tools&rft.au=Henttonen%2C+Katja+M%3BPulkkinen%2C+Mirja%3BTyrvainen%2C+Pasi.&rft.aulast=Henttonen&rft.aufirst=Katja&rft.date=2024-01-01&rft.volume=36&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Scandinavian+Journal+of+Information+Systems&rft.issn=09050167&rft_id=info:doi/","Open source software; governance; FOSS; Computers; Free software; open-source software; software ecosystem; Public domain; ecosystem health; Misalignment; orchestration; Players; public sector; Public sector; Qualitative analysis","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine how projects engage in distinct ""discursive modulation practices"" to imprint the community's shared core doctrines and design principles onto the software thereby shaping its novelty and complexity. We borrow the concept of modulation from audio synthesis to explain how a preexisting signal-in our case, the ongoing community discourse-is modulated to produce varying sounds-in our case, the novelty and complexity of the software. The concept of modulation offers a lens to understand how emergent, community-wide development activities are influenced by filtering discursive positions and mixing those positions, thereby shaping the artifact's novelty and complexity. Our research shows that the modulation of novelty exhibits a range from ""proximal"" to ""distal"" searches for new features, while the modulation of complexity varies between ""integration"" and ""deprecation."" By drawing on these concepts, we formulate a theory that explains how modulation results in alternative OSS community approaches to shaping software novelty and complexity and how this process reflects and is reflected in the resulting software artifact.","2024-12","2025-04-25 16:59:09","2025-04-25 16:59:09","","1395","","4","48","","","","","","","","","","English","","","ABI/INFORM Global","3151242275","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Discursive+Modulation+in+Open+Source+Software%3A+How+Online+Communities+Shape+Novelty+and+Complexity&rft.au=Lindberg%2C+Aron%3BBerente%2C+Nicholas%3BHowison%2C+James%3BLyytinen%2C+Kalle.&rft.aulast=Lindberg&rft.aufirst=Aron&rft.date=2024-12-01&rft.volume=48&rft.issue=4&rft.spage=1395&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2023%2F16872","Open source software; Computers; Virtual communities; Software engineering; Social networks; Software development; Innovations; Hierarchies; Complexity; Artifacts; Collaborative learning; Modulation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context.Plain English SummaryCan rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-04-25 16:59:09","2025-04-25 16:59:09","","1449-1469","","4","63","","","","","","","","","","English","","","ABI/INFORM Global","3129871390","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Small+Business+Economics&rft.atitle=Financing+A+Free-for-All%3A+Crowdfunding+Open-Source+Software&rft.au=Bort%2C+James%3BMeoli%2C+Azzurra%3BSullivan%2C+David+W..&rft.aulast=Bort&rft.aufirst=James&rft.date=2024-12-01&rft.volume=63&rft.issue=4&rft.spage=1449&rft.isbn=&rft.btitle=&rft.title=Small+Business+Economics&rft.issn=0921898X&rft_id=info:doi/10.1007%2Fs11187-023-00867-y","Open source software; Collaboration; OSS; Software; Open-source software; Entrepreneurship; Trust; Public domain; Entrepreneurs; 52399:All Other Financial Investment Activities; Business And Economics--Small Business; Business planning; Crowdfunding; Entrepreneurial finance; Financing; Investor behavior; Investors; L26; O30; O34; O36; Resource mobilization; Rewards; Value; Ventures","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Best practices suggest employing UX Capability Maturity Models (UXCMMs), which often specify an evolutionary plateau toward developing a UX-matured system and quantify organizational UX maturity into maturity levels ranging from no or ad hoc improvement to integrated continuous improvement. Numerous generically developed UXCMMs exist. However, none is created for the FOSS community, and less information is available to support their perfect match. Thus, raise suspicions if they have proper UX maturity influencing factors (UXMIFs) for the FOSS community or measure the right thing. The FOSS community differs from traditional software-developing communities and may have different dynamics and UXMIFs, necessitating unique and new methodologies for their discovery. This study, therefore, aims to identify the FOSS community’s UXMIFs and evaluate the community’s knowledge of UX maturity-related concepts. Its findings may help future researchers, practitioners, and other FOSS developers to develop UXCMMs exclusive to the FOSS community. The study’s design is both qualitative and quantitative. It adopted a systematic literature review, interviews, fuzzy Delphi Method, and thematic analysis to collect and analyze data and present the findings. The study’s sample included sixty-two active FOSS projects, fifteen FOSS stakeholders, and twelve UX experts. The outcome shows that 84% of UX experts agreed on the thirty-six FOSS’s UXMIFs with threshold d = 0.143 and crisp values greater than α-cut = 0.5. User feedback and adopted technologies were ranked first, while learnability and use speed were ranked last. Similarly, FOSS stakeholders have shown a shared understanding of UX maturity, connected concepts, and impacting factors.","2024-11","2025-04-25 16:59:10","2025-04-25 16:59:10","","7162-7178","","22","40","","","","","","","","","","English","","","ABI/INFORM Global","3128679414","","","Place: Norwood Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Human+-+Computer+Interaction&rft.atitle=The+Factors+Affecting+User+Experience+Maturity+in+Free+and+Open+Source+Software+Community%3A+An+Empirical+Study&rft.au=Namayala%2C+Phesto+P%3BKondo%2C+Tabu+S%3BMselle%2C+Leonard+J.&rft.aulast=Namayala&rft.aufirst=Phesto&rft.date=2024-11-01&rft.volume=40&rft.issue=22&rft.spage=7162&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Human+-+Computer+Interaction&rft.issn=10447318&rft_id=info:doi/10.1080%2F10447318.2023.2262270","Open source software; Interviews; Qualitative research; User experience; Literature reviews; Qualitative analysis; Best practice; Continuous improvement; Delphi method; free and open-source software; Fuzzy Delphi Method; maturity; Sociology--Computer Applications; UX maturity influencing factors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the security communities realize some limitations when they put most existing proposals into practice. The challenges are mainly concerned with (i) fine-grained unknown attack detection and (ii) ever-changing legitimate traffic adaptation. To tackle these problem, we present three key design norms. The core idea is to construct a model to split the data distribution hyperplane and leverage the concept of isolation, as well as advance the incremental model update. We utilize the isolation tree as the backbone to design our model, named FOSS, to echo back three norms. By analyzing the popular dataset of network intrusion traces, we show that FOSS significantly outperforms the state-of-the-art methods. Further, we perform an initial deployment of FOSS by working with the Internet Service Provider (ISP) to detect distributed denial of service (DDoS) attacks. With real-world tests and manual analysis, we demonstrate the effectiveness of FOSS to identify previously-unseen attacks in a fine-grained manner.","2024","2025-04-25 16:59:10","2025-04-25 16:59:10","","3945-3960","","5","32","","","","","","","","","","English","","","ABI/INFORM Global","3117135702","","","Place: New York Publisher: The Institute of Electrical and Electronics Engineers, Inc.

The path analysis and bootstrap samples revealed that customers who exhibit a high innate innovativeness and feel that they belong in the online community show a greater motivation towards platform exploration and participation in co-creation. Moreover, the effect of this synergic interaction on their co-creation participation was partially mediated by the normative dimension of their intrinsic motivation, while the hedonic dimension was not a strong predictor of co-creation contributions.

The study aims to assist a community of OSS developers in quantifying the product’s reliability. This research proposes reliability growth models for OSS by incorporating dynamicity in the debugging process. For this, stochastic differential equation-based analytical models are developed to represent the instantaneous rate of error generation. The fault introduction rate is modeled using exponential and Erlang distribution functions. The empirical applications of the proposed methodology are verified using the real-life failure data of the Open Source Software projects, GNU Network Object Model Environment, and Eclipse. A soft computing technique, Genetic Algorithm, is applied to estimate model parameters. Cross-validation is also performed to examine the forecasting efficacy of the model. The predictive power of the developed models is compared with various benchmark studies. The data analysis is conducted using the R statistical computing software. The results demonstrate the proposed models’ efficacy in parameter estimation and predictive performance. In addition, the optimal release time policy based on the proposed mathematical models is presented by formulating the optimization model that intends to minimize the total cost of software development under reliability constraints. The numerical illustration and sensitivity analysis exhibit the proposed problem's practical significance. The findings of the numerical analysis exemplify the proposed study's capability of decision-making under uncertainty.","2024-09","2025-04-25 16:59:10","2025-04-25 16:59:10","","531-569","","1","340","","","","","","","","","","English","","","ABI/INFORM Global","3098031040","","","Place: New York Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Annals+of+Operations+Research&rft.atitle=Stochastic+debugging+based+reliability+growth+models+for+Open+Source+Software+project&rft.au=Singhal%2C+Shakshi%3BKapur%2C+P.+K.%3BKumar%2C+Vivek%3BPanwar%2C+Saurabh.&rft.aulast=Singhal&rft.aufirst=Shakshi&rft.date=2024-09-01&rft.volume=340&rft.issue=1&rft.spage=531&rft.isbn=&rft.btitle=&rft.title=Annals+of+Operations+Research&rft.issn=02545330&rft_id=info:doi/10.1007%2Fs10479-023-05240-6","Open source software; Computers; Data analysis; Software reliability; Software development; Genetic algorithms; Public domain; Performance prediction; Industrial development; Cost analysis; Debugging; Differential equations; Distribution functions; Effectiveness; Error analysis; Growth models; Industry 4.0; Mathematical analysis; Numerical analysis; Optimization models; Parameter estimation; Parameter sensitivity; Probability distribution functions; Sensitivity analysis; Soft computing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In turn, specifying and evaluating OSS quality has become a significant challenge for OSS adoption in organizations that are inclined to use them. Although many OSS quality models have been proposed in the literature, the dynamic and diverse nature of OSS has caused these models to be heterogeneous in terms of structure and content. This has adversely affected the standardization of evaluations and led to the evaluation results obtained from different OSS quality models for the same purpose being incomparable and sometimes unreliable. Therefore, in this study, a meta-model for OSS quality (OSS-QMM), which employs a unified structure from existing quality models and enables the derivation of homogeneous models, has been proposed. For this purpose, a systematic and laborious effort has been spent via a step-based meta-model creation process including review-and-revise iterations. In order to validate the OSS-QMM, case study and expert opinion methods have been applied to answer three research questions (RQs) targeted to investigate practical applicability, results comparability, and effectiveness of using the meta-model. Multiple and embedded case study designs have been employed for evaluating three real ERP systems, and 20 subject matter experts have been interviewed during the validation process. The results of multi-faceted empirical studies have indicated that the OSS-QMM has addressed solving problems in OSS quality evaluation and its adoption with high degrees of confidence.","2024-06","2025-04-25 16:59:10","2025-04-25 16:59:10","","487-541","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","3070116394","","","Place: Dordrecht Publisher: Springer Nature B.V.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Quality+evaluation+meta-model+for+open-source+software%3A+multi-method+validation+study&rft.au=Y%C4%B1lmaz%2C+Nebi%3BTarhan%2C+Ay%C3%A7a+Koluk%C4%B1sa.&rft.aulast=Y%C4%B1lmaz&rft.aufirst=Nebi&rft.date=2024-06-01&rft.volume=32&rft.issue=2&rft.spage=487&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-023-09658-w","Open source software; Software; Case studies; Software quality; Enterprise resource planning; Public domain; Computers--Software; Quality assessment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Mostramos que una gestión sinérgica de la marca y la comunidad de desarrolladores – manteniendo un alto grado de control sobre ambas – puede permitir la explotación de sus complementariedades.","2024","2025-04-25 16:59:10","2025-04-25 16:59:10","","52-66","","1","28","","","","","","","","","","English","","","ABI/INFORM Global","3015030030","","","Place: Montréal Publisher: Management International","","; ","https://media.proquest.com/media/hms/PFT/1/LWlkX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=BuzVbQbhYSCwcSZJpONq7SIDfp0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+International&rft.atitle=Le+r%26ocirc%3Ble+de+la+marque+dans+le+business+model+des+%26eacute%3Bditeurs+de+logiciels+open+source%26nbsp%3B%3A+une+%26eacute%3Btude+de+cas&rft.au=Corbel%2C+Pascal%3BKadji+Ngassam%2C+Martial.&rft.aulast=Corbel&rft.aufirst=Pascal&rft.date=2024-01-01&rft.volume=28&rft.issue=1&rft.spage=52&rft.isbn=&rft.btitle=&rft.title=Management+International&rft.issn=12061697&rft_id=info:doi/10.59876%2Fa-bbwn-wasa","Open source software; Business And Economics--Management; Open source; Business model; appropriation; open-source software; Business models; Technological change; Innovations; apropiación; brand; business model; logiciel open source; marca; marque; modelo de negocio; software de código abierto","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article we investigate the structure and the coordination practices adopted by development teams during the bug-fixing process, which is considered one of main areas of FLOSS project success. In particular, based on a codification of the messages recorded in the bug tracking system of four projects, we identify the accomplished tasks, the adopted coordination mechanisms, and the role undertaken by both the FLOSS development team and the FLOSS community. We conclude with suggestions for further research.","2008","2025-04-25 16:59:10","2025-04-25 16:59:10","","1-30","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954644395","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/KG6YX?_a=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%3D%3D&_s=iDEkf1pug8ELx6vBEmykANluda0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Bug+Fixing+Practices+within+Free%2FLibre+Open+Source+Software+Development+Teams&rft.au=Crowston%2C+Kevin%3BScozzi%2C+Barbar.&rft.aulast=Crowston&rft.aufirst=Kevin&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040101","Open source software; Open source; Software; Open-source software; Coordination; Teams; Software development; Distributed computing; Computers--Data Base Management; Tracking systems; Bulletin boards; Codification; Fixing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS development takes online community as its organizational form, and developers voluntarily work for the project. In the project execution process, control aligns individual behaviors toward the organizational goals via the Internet and becomes critical to the success of OSS projects. This paper investigates the control modes in OSS project communities, and their effects on project performance. Based on a web survey and archival data from OSS projects, it is revealed that three types of control modes, that is, outcome, clanship, and self-control, are effective in an OSS project community. The study contributes to a better understanding of OSS project organizations and processes, and provides advice for OSS development.","2011","2025-04-25 16:59:10","2025-04-25 16:59:10","","26-42","","1","22","","","","","","","","","","English","","","ABI/INFORM Global","2954642973","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/FF6YX?_a=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%3D%3D&_s=eR6mIJMXjWbAL%2Fsn%2Bk7epfAXKLA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=A+Study+of+Open+Source+Software+Development+from+Control+Perspective&rft.au=Lin%2C+Zhangxi%3BXu%2C+Bo%3BXu%2C+Yan.&rft.aulast=Lin&rft.aufirst=Zhangxi&rft.date=2011-01-01&rft.volume=22&rft.issue=1&rft.spage=26&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2011010102","Open source software; Open source; Software Development; Software; Open-source software; Software development; Control; Open Source Software (OSS); Software industry; Computers--Data Base Management; Industrial development; Open; OSS Development; Outcome; Project Management; Self-control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, using the GINI coefficient as a measure of inequality within the developer group.","2008","2025-04-25 16:59:10","2025-04-25 16:59:10","","31-57","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954642921","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/VE6YX?_a=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%3D%3D&_s=%2FKtwwtxNqxDUu%2FrbSm1WOFgxmxw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Exploring+the+Effects+of+Process+Characteristics+on+Products+Quality+in+Open+Source+Software+Development&rft.au=Koch%2C+Stefan%3BNeumann%2C+Christian.&rft.aulast=Koch&rft.aufirst=Stefan&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=31&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040102","Open source software; Open source; Software; Software development; Product design; Impact analysis; Public domain; Computers--Data Base Management; Source code; Gini coefficient; Repositories","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However (1) the adoption of BI tools remains relatively low (2) the acquisition costs of proprietary BI tools are relatively high and (3) the level of satisfaction with these BI tools remain low. Given the potential of open source BI (OSBI) tools, there is a need for analyzing barriers that prevent organizations from adopting OSBI. Drawing a systematic review and a Qualitative Survey of BI Experts, this study proposes a framework that categorizes and structures 23 barriers to OSBI adoption by organizations including 4 that were identified by BI Experts but not explicitly found in the literature.

In recent years, this phenomenon has increasingly manifested in virtual collaborative spaces such as open‐source software communities because of the advancement in the use of online technologies and the heightened need for distance work. However, it is still unclear which underlying mechanisms foster collaboration in these spaces. By using the Linux kernel open‐source software community as a case study, we analyze data from the linux‐pci@vger.kernel.org mailing list to model the influence of proximity on the likelihood of collaboration between individuals. Our dataset is composed of 10,513 message replies to the PCI mailing list posted by its 654 active members in the years 2013 to 2015. Our results show that geographical proximity does not have a direct impact on collaboration, while organizational features defined by institutional and organizational proximity do significantly affect collaboration.

In the formative period, entrepreneurs were interested in the software's strategic direction in the market, academics and SMEs in software functionality and large firms and hobbyists in software testing. Each group retained its primary interest in the maturing period with academics and SMEs separating into server- and client-side usability. The analysis shed light on how the different stakeholder groups overcame tensions amongst themselves and took specific actions to sustain the project.Originality/valueThe authors extend stakeholder theory by reconceptualizing the focal organization and its stakeholders for OSS projects. To date, OSS research has primarily focused on examining one project relative to its marketplace. Using stakeholder theory, we identified stakeholder groups within a single OSS project to demonstrate their distinct interests and how these interests influence their value creation activities over time. Collectively, these interests enable the project's long-term development.","2023","2025-04-25 16:59:11","2025-04-25 16:59:11","","3048-3078","","7","36","","","","","","","","","","English","","","ABI/INFORM Global","2919795922","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/yExBX?_a=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%3D%3D&_s=z0viFxlTm14pG0ZvB1tVTH8hCe4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=How+do+different+stakeholder+groups+within+an+open+source+software+project+influence+the+project%27s+development%3A+a+case+study+of+OpenSimulator&rft.au=Paul+Di+Gangi%3BTeigland%2C+Robin%3BYetis%2C+Zeynep.&rft.aulast=Paul+Di+Gangi&rft.aufirst=&rft.date=2023-10-01&rft.volume=36&rft.issue=7&rft.spage=3048&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-10-2021-0751","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Research; Success; Text analysis; Strategy; Case studies; Virtual community; Stakeholders; Software testing; Case study; Public domain; Investigations; Software project management; Entrepreneurs; Value creation; Value proposition; Library And Information Sciences--Computer Applications; Small & medium sized enterprises-SME; Academic staff; FLOSS (Open source software); Formal organization; Mailing lists; OpenSimulator; Stakeholder theory; Time use; Virtual world","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software maintenance is required to fix bugs, to add new features, to improve performance, and/or to adapt to a changed environment. In this article, we examine change in cognitive complexity and its impacts on maintenance in the context of open source software (OSS). Relationships of the change in cognitive complexity with the change in the number of reported bugs, time taken to fix the bugs, and contributions from new developers are examined and are all found to be statistically significant. In addition, several control variables, such as software size, age, development status, and programmer skills are included in the analyses. The results have strong implications for OSS project administrators; they must continually measure software complexity and be actively involved in managing it in order to have successful and sustainable OSS products.

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume – suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.","2017","2025-04-25 16:59:11","2025-04-25 16:59:11","","43-66","","2","29","","","","","","","","","","English","","","ABI/INFORM Global","2866855510","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/wC7YX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=QS%2FEW1SXZDT0EEcTLA0f0RbsTzY%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+and+End+User+Computing&rft.atitle=Developers%2C+Quality+Control+and+Download+Volume+in+Open+Source+Software+%28OSS%29+Projects&rft.au=Hill%2C+Geoffrey%3BDatta%2C+Pratim%3BCandice+Vander+Weerdt.&rft.aulast=Hill&rft.aufirst=Geoffrey&rft.date=2017-04-01&rft.volume=29&rft.issue=2&rft.spage=43&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+and+End+User+Computing&rft.issn=15462234&rft_id=info:doi/10.4018%2FJOEUC.2017040103","Open source software; Open source; Software; Open-source software; Open Source Software; Quality control; Segmented Regression; Software development; Computers--Electronic Data Processing; Developer Limit; Downloading; Quality Control; Quality Control Index; Regression Discontinuity; Tragedy of the commons","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standardization in OSS quality is of vital importance as a communication vehicle for stakeholders in identifying and selecting high-quality products. Thus, meta-models help to define a standardized language and enable to propose quality models that can be used to perform comparable measurements.ObjectiveConsidering the lack of a comprehensive meta-model of OSS quality in the literature, there appears a need to see a more complete picture of OSS quality and to represent its concepts more formally. Therefore, in this study, it is aimed to develop a solid base for a comprehensive meta-model of OSS quality to create a common understanding among stakeholders.MethodA systematic way has been followed toward developing a common structure, defining a consistent terminology and, finally, providing a meta-model of OSS quality. In this context, (1) the common structure of the quality models for OSS has been investigated, (2) the terms of the general-purpose meta-models of software quality have been analyzed based on the international standards, and (3) the terms of the quality models for OSS have been mapped with the elements of these meta-models.ResultsAn initial meta-model of OSS quality, which employs a unified structure from the OSS quality models and eliminates the inconsistencies determined in the general-purpose meta-models of software quality, has been proposed and an implementation of this meta-model has been demonstrated.ConclusionThis initial meta-model of OSS quality with a standard terminology can be taken as a guide by researchers who will propose or revise their OSS quality models. It will allow developing multiple OSS quality models with homogenous structure and terms, and also enable comparing the evaluation results obtained by these models.","2023-09","2025-04-25 16:59:11","2025-04-25 16:59:11","","721-773","","3","31","","","","","","","","","","English","","","ABI/INFORM Global","2859386662","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/v6eiU?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=wb6Jpkyf0TWqIBbsCGHf2Lyhalk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Matching+terms+of+quality+models+and+meta-models%3A+toward+a+unified+meta-model+of+OSS+quality&rft.au=Y%C4%B1lmaz%2C+Nebi%3BTarhan%2C+Ay%C3%A7a+Koluk%C4%B1sa.&rft.aulast=Y%C4%B1lmaz&rft.aufirst=Nebi&rft.date=2023-09-01&rft.volume=31&rft.issue=3&rft.spage=721&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-022-09603-3","Open source software; OSS; Software; Open-source software; Context; Software quality; Terminology; Standardization; Computers--Software; Meta-model; Metamodeling; Quality evaluation; Quality measurement; Quality metrics; Quality model; Quality standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The model is extracted to support source code reusing and revising as the two primary targets of OSS through a systematic review of related documents.Design/methodology/approachConducting a systematic review, all the software reusing criteria are identified and introduced to the web of data by an ontology for OSS (O4OSS). The software semantic model introduced in this paper explores OSS through triple expressions in which the O4OSS properties are predicates.FindingsThis model improves the quality of web data by describing software in a structured machine–human readable profile, which is linked to the related data that was previously published on the web. Evaluating the OSS semantic model is accomplished through comparing it with previous approaches, comparing the software structured metadata with profile index of software in some well-known repositories, calculating the software retrieval rank and surveying domain experts.Originality/valueConsidering context-specific information and authority levels, the proposed software model would be applicable to any open and close software. Using this model to publish software provides an infrastructure of connected meaningful data and helps developers overcome some specific challenges. By navigating software data, many questions which can be answered only through reading multiple documents can be automatically responded on the web of data.","2023","2025-04-25 16:59:11","2025-04-25 16:59:11","","685-707","","4","75","","","","","","","","","","English","","","ABI/INFORM Global","2830442491","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/vsAXS?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzMzA3MDIKMjgzMDQ0MjQ5MToNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDIzLzA3LzAxcgoyMDIzLzA4LzMxegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAg9BcnRpY2xlfEZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=MSd3SwkOlhi0fHhVlE4D7wu73Ro%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Aslib+Journal+of+Information+Management&rft.atitle=A+semantic+model+to+publish+open+source+software+on+the+web+of+data&rft.au=Mosharraf%2C+Maedeh.&rft.aulast=Mosharraf&rft.aufirst=Maedeh&rft.date=2023-07-01&rft.volume=75&rft.issue=4&rft.spage=685&rft.isbn=&rft.btitle=&rft.title=Aslib+Journal+of+Information+Management&rft.issn=20503806&rft_id=info:doi/10.1108%2FAJIM-09-2021-0280","Open source software; Library And Information Sciences; Collaboration; Open source; Software; Open-source software; Software packages; Metadata; Natural language; Semantics; Open data; Software development; Systematic review; Public domain; Source code; Documents; Linked data; Linked Data; Moodle; Ontology; Publishing; Semantic model; Semantic web; Software model; Web of data","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A prime example for this phenomenon is open source software (OSS) development, where multiple actors contribute to a public good, which is also integrated into company-owned software products. Despite the importance of aligning community work on the public good with own in-house development efforts, firms have limited options to directly control the OSS project or the project's outcome. This research reflects on resource deployment control, a control mode in which firms assign own developers to work for an OSS project to influence the OSS project, and tests hypotheses on individual developer levels.Design/methodology/approachThis research tests the effect of perceived resource deployment control on opinion leadership by analyzing employed Linux kernel developers.FindingsThe findings show that developers who perceive being assigned to an OSS project to enact control also exhibit opinion leadership. This research also investigates boundary conditions such as the OSS business model a firm operates and the reputation developers assign to the developers' employer.Originality/valueThis research is the first that is devoted to resource deployment control, and the research closes with a discussion of implications for control theory and the management of innovation beyond firm boundaries.","2023","2025-04-25 16:59:11","2025-04-25 16:59:11","","1645-1668","","4","36","","","","","","","","","","English","","","ABI/INFORM Global","2808164080","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/FztSR?_a=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%3D%3D&_s=Zh%2B34DtfoD4Yld7S8M4N0fMj1oE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=Innovating+beyond+firm+boundaries%3A+resource+deployment+control+in+open+source+software+development&rft.au=Schaarschmidt%2C+Mario.&rft.aulast=Schaarschmidt&rft.aufirst=Mario&rft.date=2023-05-20&rft.volume=36&rft.issue=4&rft.spage=1645&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-08-2021-0624","Open source software; Innovation; Leadership; Information systems; Boundaries; Information technology; Collaboration; Open source; Open-source software; Linux; Companies; Intellectual property; Software development; Business models; Control theory; Public domain; Systems development; Innovations; Research & development--R&D; Employees; Library And Information Sciences--Computer Applications; Assignment; Boundary conditions; Community work; Deployment; Developer survey; Open source business model; Opinion leadership; Perceived control; Resource deployment control","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks.Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.Originality/value This study is the first attempt to consider the network metrics in both module networks of the technical sub-system and developer networks of the social sub-system to better understand their influences on project success.","2023","2025-04-25 16:59:12","2025-04-25 16:59:12","","895-915","","2","36","","","","","","","","","","English","","","ABI/INFORM Global","2787783369","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/HROxQ?_a=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%3D%3D&_s=K%2FslBwH0OOutLsUnP1mOAPTsYXY%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=Social-technical+network+effects+in+open+source+software+communities%3A+understanding+the+impacts+of%26nbsp%3Bdependency+networks+on%26nbsp%3Bproject+success&rft.au=Wu%2C+Jiang%3BHuang%2C+Xiao%3BWang%2C+Bin.&rft.aulast=Wu&rft.aufirst=Jiang&rft.date=2023-02-15&rft.volume=36&rft.issue=2&rft.spage=895&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2FITP-09-2021-0684","Design; Open source software; Social network analysis; Information technology; Collaboration; Open source; Software engineering; Software; Computer architecture; Software reliability; Research; Success; Teams; Social networks; Software development; Software quality; Public domain; Investigations; Project Success; Network effect; Social network; Library And Information Sciences--Computer Applications; Dependency; Closeness; Dependency network; Dependency networks; Modules; Open source software community; Social-technical system","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software.Design/methodology/approach>A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76%.Findings>The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff.Research limitations/implications>This study is geographically limited to the university libraries in Islamabad.Practical implications>This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries.Originality/value>This study concludes that the development of IRs in university libraries is a need of the hour. Although the launching of IRs requires certain skills and competencies, Pakistani librarians can overcome these challenges by mastering the ICT skills.","2023","2025-04-25 16:59:12","2025-04-25 16:59:12","","47-55","","1","51","","","","","","","","","","English","","","ABI/INFORM Global","2761066259","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/qXtPQ?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=q97LwmwamKrUnhQo4p8fi9qVmUI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Discovery+and+Delivery&rft.atitle=Open+source+software+adoption+for+development+of+institutional+repositories+in+university+libraries+of+Islamabad&rft.au=Muhammad+Kabir+Khan%3BArslan+Sheikh.&rft.aulast=Muhammad+Kabir+Khan&rft.aufirst=&rft.date=2023-01-01&rft.volume=51&rft.issue=1&rft.spage=47&rft.isbn=&rft.btitle=&rft.title=Information+Discovery+and+Delivery&rft.issn=23986247&rft_id=info:doi/10.1108%2FIDD-10-2021-0113","Open source software; Library And Information Sciences; Open source; Open-source software; Dissertations & theses; 51921:Libraries and Archives; Digital libraries; Digital preservation; Academic libraries; Digital library; Digital library system; Free softwares; Institutional repositories; Institutional repository; Islamabad Pakistan; Librarians’ challenges; Librarians’ perceptions; Library; Library science; Pakistan; Repository","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Além disso, a governança não segue um ciclo sequencial de aprimoramento, modificando-se na presença de atores organizacionais externos como patrocinadores. Isso sugere a necessidade de uma governança estratégica e flexível para lidar com a aquisição e alocação de recursos organizacionais.

This paper analyzes the governance of these organizations from the perspective of their structure and control, considering the development trajectory of three community-based free software projects in Brazil. Results show that the constant need to produce modern technologies gives rise to external pressures that promote change - albeit temporary - in the governance of these projects, making them resemble a cathedral more than a bazaar. Governance does not follow a cycle of sequential improvement; it changes depending on the external organizational actors present, such as sponsors. This suggests the need for strategic and flexible governance to deal with the acquisition and allocation of organizational resources. Governance of the projects described here varies along a spectrum of (in)formality that allows both production models - cathedral or bazaar - to exist in the same organization at different periods.","2022-02","2025-04-25 16:59:12","2025-04-25 16:59:12","","1-17","","1","62","","","","","","","","","","English","","","ABI/INFORM Global","2623909517","","","Place: São Paulo Publisher: Fundação Getulio Vargas","","; ","https://media.proquest.com/media/hms/PFT/1/jxy7M?_a=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&_s=BGaGruidEWusyM75C8u5eUdG78o%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revista+de+Administra%C3%A7%C3%A3o+de+Empresas&rft.atitle=TRANSFORMATION+OF+FREE+AND+OPEN+SOURCE+SOFTWARE+DEVELOPMENT+PROJECTS%3A+GOVERNANCE+BETWEEN+THE+CATHEDRAL+AND+BAZAAR&rft.au=Ferraz%2C+Isabela+Neves%3BDos+Santos%2C+Carlos+Denner.&rft.aulast=Ferraz&rft.aufirst=Isabela&rft.date=2022-01-01&rft.volume=62&rft.issue=1&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Revista+de+Administra%C3%A7%C3%A3o+de+Empresas&rft.issn=00347590&rft_id=info:doi/10.1590%2FS0034-759020220104","Open source software; Business And Economics--Management; Virtual communities; Open source; Transformation; Governance; Software development; Freeware; Resource allocation; Bureaucracy; Development programs","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg’s motivation-hygiene framework, we explore how developers’ perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022-01","2025-04-25 16:59:12","2025-04-25 16:59:12","","165-195","","1","23","","","","","","","","","","English","","","ABI/INFORM Global","2619733915","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/Ydh4M?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=I9YhzKEzKqnQYd%2FlycaVgvqO4Cc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=A+Motivation-Hygiene+Model+of+Open+Source+Software+Code+Contribution+and+Growth&rft.au=Sharma%2C+Pratyush+Nidhi%3BDaniel%2C+Sherae+L%3BTingting+%28Rachel%29+Chung%3BGrover%2C+Varun.&rft.aulast=Sharma&rft.aufirst=Pratyush&rft.date=2022-01-01&rft.volume=23&rft.issue=1&rft.spage=165&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00712","Open source software; Motivation; Information systems; Growth; Open source; Software; Open-source software; Computers--Information Science And Information Theory; Public domain; Source code; Growth models; A Motivation-Hygiene Model of Open Source Software Code Contribution and Growth; Computer program; Hygiene","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-04-25 16:59:12","2025-04-25 16:59:12","","8","","","49","","","","","","","","","","English","","","ABI/INFORM Global","2582094786","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/x0MyK?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=uaAEFLA0RlKKUmWt5wvgE5szUa4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Episodic+Peripheral+Contributors+and+Technical+Dependencies+in+Open+Source+Software+%28OSS%29+Ecosystems&rft.au=Moon%2C+Eunyoung.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2021-01-01&rft.volume=49&rft.issue=&rft.spage=8&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04908","Open source software; Open source; Software engineering; Software; Open-source software; Open Source Software; Computers--Information Science And Information Theory; Strategic planning; Containers; Software Ecosystems; Code reuse; Episodic Volunteering; Hierarchies; Lenses; Peripheral Contributors; Software Coupling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Choice process episodes were selected as the unit of analysis and were coded for the task trigger and topic. The impact of these factors on participation (i.e. the numbers of participants and messages) was assessed by regression.FindingsThe results reveal differences in participation related to different task triggers and task topics. Further, the results suggest the mediating role of the number of participants in the relationships between task characteristics and the number of messages. The authors also speculate that project type serves as a boundary condition restricting the impacts of task characteristics on the number of participants and propose this relationship for future research.Research limitations/implicationsEmpirical support was provided to the important effects of different task characteristics on individual participation behaviors in FLOSS development tasks.Practical implicationsThe findings can help FLOSS participants understand participation patterns in different tasks and choose the types of tasks to attend to.Originality/valueThis research explores the impact of task characteristics on participation in FLOSS development at the task level, while prior research on participation in FLOSS development has focused mainly on factors at the individual and/or project levels.","2021","2025-04-25 16:59:12","2025-04-25 16:59:12","","1177-1202","","4","31","","","","","","","","","","English","","","ABI/INFORM Global","2550176960","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/TmssJ?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=H5D3nvUhF2oBsTBAEDsGKUrVvmM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Internet+Research&rft.atitle=Participation+in+community-based+free%2Flibre+open+source+software+development+tasks%3A+the+impact+of+task+characteristics&rft.au=Kangning+Wei%3BCrowston%2C+Kevin%3BEseryel%2C+U+Yeliz.&rft.aulast=Kangning+Wei&rft.aufirst=&rft.date=2021-01-01&rft.volume=31&rft.issue=4&rft.spage=1177&rft.isbn=&rft.btitle=&rft.title=Internet+Research&rft.issn=10662243&rft_id=info:doi/10.1108%2FINTR-03-2020-0112","Open source software; Behavior; Social interaction; Computers--Internet; Open source; Participation; Electronic mail; Open-source software; Coordination; Research; Free/libre open source software (FLOSS); Teams; Messages; Software development; Crowdsourcing; Public domain; Freeware; Empirical analysis; Computer Software; Free and open-source software; Community Relations; Boundary conditions; Community participation; Interpersonal Relationship; Leadership Effectiveness; Longitudinal Studies; Task characteristics; Work Environment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So it was important to reassess the factors enabling OSS adoption in order to enhance OSS utilization within public sector organisations. This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lenses of technology adoption theories (i.e, Diffusion of Innovation (DOI) theory and Technology Acceptance Model (TAM)), and OSS adoption literature. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS. The findings suggested that Rogers’ relative advantage and compatibility constructs are major enablers while organisational attributes, environmental attributes, and TAM’s attributes also had some influence on OSS adoption.","2012","2025-04-25 16:59:13","2025-04-25 16:59:13","","","","2","17","","","","","","","","","","English","","","ABI/INFORM Global","2546081220","","","Place: Wollongong Publisher: Australasian Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/na1qJ?_a=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&_s=xNWN%2FZf9JyIZADy5hXjgvNRqXn0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Australasian+Journal+of+Information+Systems&rft.atitle=Enablers+of+Open+Source+Software+adoption%3A+A+case+study+of+APS+organisations&rft.au=Gurusamy%2C+Kavitha%3BCampbell%2C+John.&rft.aulast=Gurusamy&rft.aufirst=Kavitha&rft.date=2012-01-01&rft.volume=17&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Australasian+Journal+of+Information+Systems&rft.issn=14498618&rft_id=info:doi/10.3127%2Fajis.v17i2.731","Open source software; Open source; Software; Open-source software; Open Source Software; Technology acceptance model; Technology adoption; Computers--Computer Systems; Public domain; Public sector; Australia; Australian Public Sector; Diffusion of Innovation theory; Maintainability; Technology Acceptance Model; Technology adoption theories; Technology utilization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The exploratory research was a preliminary contact with the investigated field to make the arguments presented more reliable. Among the reflections, it is observed that even though it is possible to distinguish community-based free software projects from traditional organizations, a crucial factor not always considered are the transformations resulting from the development of these projects. It is necessary that the studies consider the context of functioning, as well as the changes and interorganizational relationships established by the projects over time.

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-04-25 16:59:13","2025-04-25 16:59:13","","20","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2500501225","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/JGBVI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=TumiZGundAt%2FGKwb2yVCFBQfkxQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Decision-making+Processes+in+Community-based+Free%2FLibre+Open+Source+Software-development+Teams+with+Internal+Governance%3A+An+Extension+to+Decision-making+Theory&rft.au=Eseryel%2C+U+Yeliz%3BKangning+Wei%3BCrowston%2C+Kevin.&rft.aulast=Eseryel&rft.aufirst=U&rft.date=2020-01-01&rft.volume=46&rft.issue=&rft.spage=20&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.04620","Open source software; Decision making; Computers--Information Science And Information Theory; Teams; Software development; Decision-making; Public domain; Freeware; Decision analysis; Decision theory; Electric power distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.

Special emphasis is placed on the legal ramifications of this alternative approach to business software development and a long, complex lawsuit that threatens to restructure the open source philosophy. It is not surprising that commercial software companies have attacked Linux and other open source software packages. A legal attack from a company called SCO could jeopardize the future of open source software, with users and potential users of open source software fearful of previously unasserted intellectual property lawsuits. On Mar 6, 2003, the SCO Group initiated a civil lawsuit again IBM, claiming damages that were later increased to $5 billion. The possibility that SCO could have some proprietary claim to Linux is negated by the free software community's willingness to rewrite any offending code. At this time, there is little reason for organizations using Linux and other open source programs to fear the results of the SCO litigation.","2006-08","2025-04-25 16:59:13","2025-04-25 16:59:13","","5-9","","3","15","","","","","","","","","","English","","","ABI/INFORM Global","229508326","","","Place: New York Publisher: Taylor & Francis Ltd.","","; ","https://media.proquest.com/media/hms/OBJ/LlDET?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU1MjQzMzIJMjI5NTA4MzI2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDcvMDFyCjIwMDYvMDgvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=zj9yCFENJ0rmQFajcsF%2Brl076qI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Security&rft.atitle=Open+Source+Software+and+the+SCO+Litigation&rft.au=Freeman%2C+Edward+H.&rft.aulast=Freeman&rft.aufirst=Edward&rft.date=2006-07-01&rft.volume=15&rft.issue=3&rft.spage=5&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Security&rft.issn=1065898X&rft_id=info:doi/","Open source software; Computers; Open source; Computer science; Open-source software; Linux; Operating systems; Intellectual property; Software development; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; United States--US; 9190:United States; Books; Personal computers; Litigation; 4330:Litigation; Computers--Computer Security; Damage claims; Lawsuit","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The open-source movement's unique development practices are challenging the traditional views of how innovation should work. Some people suggest open-source software developers freely reveal and share because they garner personal benefits from doing so, such as learning to develop complex software. Open-source projects can be started by anyone with the appropriate programming skills and motives. In the future, some managers may encourage the use of open-source software in their own firms. Others may attempt to build a business based on distributing and servicing open-source software. The open-source software movement also provides important management lessons regarding the most effective ways to structure and implement innovation. The lessons of open-source projects demonstrate the value of specialization through self-selection and how norms of meritocracy and peer recognition help ensure product quality.","2003","2025-04-25 16:59:13","2025-04-25 16:59:13","","14-18","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","224965356","","","Place: Cambridge Publisher: Massachusetts Institute of Technology, Cambridge, MA","","; ","https://media.proquest.com/media/hms/OBJ/cGueT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNjE0MjIJMjI0OTY1MzU2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDMvMDQvMDFyCjIwMDMvMDYvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=J%2FZUXiYkA9J3hvZ6bxOviM2uR3Q%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIT+Sloan+Management+Review&rft.atitle=Open-source+software+development&rft.au=Georg+von+Krogh.&rft.aulast=Georg+von+Krogh&rft.aufirst=&rft.date=2003-04-01&rft.volume=44&rft.issue=3&rft.spage=14&rft.isbn=&rft.btitle=&rft.title=MIT+Sloan+Management+Review&rft.issn=15329194&rft_id=info:doi/","Open source software; Innovation; Business And Economics--Management; Open source; Software; Open-source software; Licenses; Product development; Trends; Internet; Software development; Meritocracy; 5240:Software & systems; Public domain; Freeware; Developer; Innovations; United States--US; 9190:United States; Defense contracts; Laboratories; Organization studies; Open; Programmer; Public good; Computer programming; Projects; Self-selection bias; User needs","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper reviews relevant literature related to international operations of knowledge-intensive firms, especially in the software industry. Theoretical development is based here on a combination of the network approach, international new venture theory and inward-outward internationalization. The findings in this study suggest that the international activities of OSS firms can be divided into project activities and business activities. Project activities include inward and outward linkages, and partner identification. Business activities include domestic and partner network activities that can lead to international business as well. For scholars, the framework provides a new approach to explain many international activities of OSS firms by integrating three international business theories. In addition, it provides good starting point for further empirical examination. The framework helps managers gain a better understanding of complex circumstances embedded into the international activities of OSS firms. With that better understanding, the managers can focus their activities, which helps further to improve their firms' competitiveness engendered by the international activities in the OSS development. The framework developed in this study is believed to be the first serious attempt to provide a deeper theoretical understanding of international activities of OSS firms.

Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied - especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-04-25 16:59:13","2025-04-25 16:59:13","","227-238","","2","44","","","","","","","","","","English","","","ABI/INFORM Global","222420968","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/ORIG/5/G0cEE?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzNTA3MjIJMjIyNDIwOTY4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDUvMDEvMDFyCjIwMDUvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=YMjkzlzFjF9WOvmW0OmRjMMrL1E%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Systems+Journal&rft.atitle=The+value+of+open+standards+and+open-source+software+in+government+environments&rft.au=Simon%2C+K+D.&rft.aulast=Simon&rft.aufirst=K&rft.date=2005-04-01&rft.volume=44&rft.issue=2&rft.spage=227&rft.isbn=&rft.btitle=&rft.title=IBM+Systems+Journal&rft.issn=00188670&rft_id=info:doi/","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Evidence shows that OSS fails in many cases to displace dominant market leaders even in the case of user's unhappiness with the prevalent solution, while in some others OSS is adopted without a clear advantage. Using a qualitative research approach, we highlight the existence of a new context, in which the adoption of Linux-based OSS platforms by companies is not led only by traditional drivers. User communities and broader social responsibility considerations have been found to exert some degrees of pressure on the IT decision maker. Through the analysis of some significant cases we propose a framework that helps to depict under which conditions significant OSS adoption may unfold.","2006-03","2025-04-25 16:59:13","2025-04-25 16:59:13","","85-103","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","222358351","","","Place: Paris Publisher: Editions ESKA","","; ","https://media.proquest.com/media/hms/OBJ/0BfAT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0NjA4NjIJMjIyMzU4MzUxOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDMvMDFyCjIwMDYvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=D3MOuGnnEx1X%2FpNp2n3oJAcKa%2Bk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Syst%C3%A8mes+d%27Information+et+Management&rft.atitle=An+Exploratory+Framework+for+Assessing+Open+Source+Software+Adoption&rft.au=Miralles%2C+Francesc%3BSieber%2C+Sandra%3BValor%2C+Josep.&rft.aulast=Miralles&rft.aufirst=Francesc&rft.date=2006-03-01&rft.volume=11&rft.issue=1&rft.spage=85&rft.isbn=&rft.btitle=&rft.title=Syst%C3%A8mes+d%27Information+et+Management&rft.issn=12604984&rft_id=info:doi/","Open source software; Decision making; Qualitative research; Research methodology; Information technology; Studies; Business And Economics--Management; Open source; Software; Open-source software; Technology adoption; 5240:Software & systems; Public domain; Economic; Technological change; Systems development; 9130:Experimental/theoretical; 9175:Western Europe; France; Social responsibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through an empirical, interpretive case study and a literature review utilising the metaphor of text in the analysis, this paper provides a refined conceptualisation of user participation in OSS development. The paper reveals that different kinds of meanings have been attached to users and to their participation. User participation is both direct and indirect in the OSS development context. Some user groups actively take part in OSS development, while others are merely represented in it. Different kinds of intermediaries representing the users are identified. The research is based on one case study on a small but active OSS project with an interest in users. Other kinds of OSS projects should be analysed. The analysis was focused on a discussion forum, but users can take part in OSS development by other means as well. Paths for future work should include the gathering of more varied empirical data. The findings indicate that users can provide feedback to the development through discussion forums in the distributed environment, but there is a need to support the users in doing so and the developers in analysing the data. The importance of different kinds of intermediaries representing the users is highlighted. The paper provides thorough empirical insights and a refined conceptualisation of user participation addressing the currently weakly empirically explored OSS development context.","2009","2025-04-25 16:59:14","2025-04-25 16:59:14","","132-156","","2","22","","","","","","","","","","English","","","ABI/INFORM Global","222338127","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/FwwiT?_a=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&_s=NdT%2BgoS1qDJ7PNo2VOsmhjgpBak%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Technology+%26+People&rft.atitle=%26quot%3BConstructing+the+users%26quot%3B+in+open+source+software+development%3A+An+interpretive+case+study+of+user+participation&rft.au=Iivari%2C+Netta.&rft.aulast=Iivari&rft.aufirst=Netta&rft.date=2009-04-01&rft.volume=22&rft.issue=2&rft.spage=132&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593840910962203","Design; Open source software; Decision making; Qualitative research; Information technology; Studies; User behavior; Open source; Participation; Software engineering; Software; Open-source software; Usability; Empowerment; Software development; Case study; 5240:Software & systems; Public domain; End users; Literature review; 9130:Experimental/theoretical; Industrial democracy; Library And Information Sciences--Computer Applications; Systems design; Human-computer interaction; Intermediary; Traditions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The dependence of OR on software implies that the ways in which software is developed, managed, and distributed can have a significant impact on the field. Open source is a relatively new software development and distribution model which offers advantages over current practices. Its viability depends on the precise definition of open source, on the culture of a distributed developer community, and on a version-control system which makes distributed development possible. In this paper, we review open-source philosophy and culture, and present the goals and status of COIN-OR.","2003-01","2025-04-25 16:59:14","2025-04-25 16:59:14","","57-66","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","220690110","","","Place: Armonk Publisher: International Business Machines Corporation","","; ","https://media.proquest.com/media/hms/OBJ/eiZTT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0MTEyMzIJMjIwNjkwMTEwOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDMvMDEvMDFyCjIwMDMvMDEvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=oig6YOxcjBpD8xE4hgp6afot6Gw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IBM+Journal+of+Research+and+Development&rft.atitle=The+common+optimization+INterface+for+operations+research%3A+Promoting+open-source+software+in+the+operations+research+community&rft.au=Lougee-Heimer%2C+R.&rft.aulast=Lougee-Heimer&rft.aufirst=R&rft.date=2003-01-01&rft.volume=47&rft.issue=1&rft.spage=57&rft.isbn=&rft.btitle=&rft.title=IBM+Journal+of+Research+and+Development&rft.issn=00188646&rft_id=info:doi/","Open source software; Computers; Collaboration; Open source; Libraries; Open-source software; Peer review; Software development; Algorithms; Mathematical programming; Optimization; Public domain; Technology: Comprehensive Works; Researchers; 51921:Libraries and Archives; Application programming interface; Interfaces; Mathematical optimization; Operations research; Software distribution","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research examines why governments choose to migrate and what factors affect implementation. Drawing on a comparative case study of four cities, I find that governments decide to migrate for a range of factors, but are driven more by democratic values such as independence and self-determination than by a desire to cut costs or save money. I also find that implementation is affected by a variety factors but in particular by information technology's place within a city's organizational structure.

Software, however, is increasingly developed in open source software (OSS) forms which have several unique characteristics. In this study, we approach OSS RE as a sociotechnical, distributed cognitive process where distributed actors ""compute"" requirements- i.e., transform requirements-related knowledge into forms that foster a shared understanding of what the software is going to do and how it can be implemented. Such computation takes place through social sharing of knowledge and the use of heterogeneous artifacts. To illustrate the value of this approach, we conduct a case study of a popular OSS project, Rubinius-a runtime environment for the Ruby programming language-and identify ways in which cognitive workload associated with RE becomes distributed socially, structurally, and temporally across actors and artifacts. We generalize our observations into an analytic framework of OSS RE, which delineates three stages of requirements computation: excavation, instantiation, and testing-in-the-wild. We show how the distributed, dynamic, and heterogeneous computational structure underlying OSS development builds an effective mechanism for managing requirements. Our study contributes to sorely needed theorizing of appropriate RE processes within highly distributed environments as it identifies and articulates several novel mechanisms that undergird cognitive processes associated with distributed forms of RE.","2018","2025-04-25 16:59:14","2025-04-25 16:59:14","","1217-1252","","12","19","","","","","","","","","","English","","","ABI/INFORM Global","2172619875","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/auQH8?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=vxhN6j%2Be8Fs0IkGVdmku2nHlfT0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=%26quot%3BComputing%26quot%3B+Requirements+for+Open+Source+Software%3A+A+Distributed+Cognitive+Approach&rft.au=Xiao%2C+Xuan%3BLindberg%2C+Aron%3BHansen%2C+Sean%3BLyytinen%2C+Kalle.&rft.aulast=Xiao&rft.aufirst=Xuan&rft.date=2018-01-01&rft.volume=19&rft.issue=12&rft.spage=1217&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/10.17705%2F1jais.00525","Open source software; Interviews; Cognition; Information systems; Theory; Open source; Software engineering; Software; Open-source software; Knowledge; Research; Case studies; Computers--Information Science And Information Theory; Software development; Codes; Requirements engineering; Programming languages; Agile software development; Distributed computing; Public domain; Engineering; Cognition & reasoning; 51921:Libraries and Archives; Artifacts; Archives & records; Computation; Keywords; Requirements analysis; Verbal communication","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach – This paper uses the case study approach based on mixed methods: literature reviews and news searches, electronic surveys, qualitative interviews and observations. It combines discussions from several research projects as well as previous publications to present the scope of commercial choices within open source software and their consequences. Findings – The findings show that higher levels of involvement in open source software communities poses important questions about the balance between economic, technological, and social logics as well as the benefits of being autonomous, having access to collaborative networks and minimizing risks related to free-riding. There are six levels of commercial involvement in open source communities, and each of them is characterized by a different dilemma. Originality/value – The paper sheds light on the various level of involvement of business in open source movement and emphasize that the popularized “open innovation” concept is only the first step in real involvement and paradigm shift.","2016","2025-04-25 16:59:14","2025-04-25 16:59:14","","344-360","","3","29","","","","","","","","","","English","","","ABI/INFORM Global","2154276377","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/FIlx7?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=7%2FgAt8bWHwx7LBuGjUr96mUn598%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Change+Management&rft.atitle=Dilemmas+within+commercial+involvement+in+open+source+software&rft.au=Ciesielska%2C+Malgorzata%3BWestenholz%2C+Ann.&rft.aulast=Ciesielska&rft.aufirst=Malgorzata&rft.date=2016-04-01&rft.volume=29&rft.issue=3&rft.spage=344&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Change+Management&rft.issn=09534814&rft_id=info:doi/10.1108%2FJOCM-04-2013-0058","Open source software; Interviews; Community; Qualitative research; Business And Economics--Management; Open source; Participation; Software; Open-source software; Linux; Venture capital; Software development; Codes; Business models; Mixed-methods; Case study; Public domain; Surveys & questionnaires; Freeware; Innovations; Open innovation; Literature reviews; Open; Commercialization; Contradictory institutional logics; Dilemma","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The focus of the paper lies in a proof-of-concept for a novel means to develop and execute pervasive services, with simplicity and maintainability as prime drivers. The essence of this approach is the novel integration of the policy-based management (PBM) techniques and the model-driven architecture (MDA) techniques for specifying pervasive services and their behaviour, together with auto-generation of middleware implementation and policy enablement. The presence of policies provides pervasive services with the high flexibility and adaptability needed for dealing with changing environments and resource availabilities, while the introduction of MDA for defining pervasive service information models fundamentally solves the information modelling puzzle of current policy-based approaches. Additionally, MDA's middleware-neutral feature benefits the smooth evolution of pervasive services as a piece of software artefact in the face of heterogeneous devices and platforms. A preliminary case study has demonstrated the practical feasibility and benefits of this approach. The case study revolves around an ICT service called TEANU - transparent enterprise access for nomadic user. The service provides a means for nomadic users to maintain a secure access to their enterprise network in the presence of multiple access network providers with different service level guarantees.

This paper focuses on for-profit organizations that release software products under OSS licenses, and argues that variations in their endowments of intellectual property rights, namely patents and trademarks, help to determine which firms will tend to incorporate OSS into commercial products. We explain whether and under what conditions preexisting stocks of intellectual property rights can be useful complementary assets that allow firms to benefit directly or indirectly from commercializing OSS products, and test our hypotheses on a novel data set built on firms' announcements of OSS product releases in the specialized press between 1995 and 2003. We find three robust results: (a) firms with large stocks of software patents are more likely to release OSS products; (b) firms with large stocks of software trademarks are less likely to release OSS products; (c) firms with large stocks of hardware trademarks are more likely to release OSS products.

Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach – To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents’ opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings – The analysis of the data reveals that the individual participant’s satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value – Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members’ satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.","2015","2025-04-25 16:59:15","2025-04-25 16:59:15","","791-813","","4","19","","","","","","","","","","English","","","ABI/INFORM Global","2138080131","","","Place: Kempston Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/KZxi7?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=%2B16Ipv0d5ANX8qBpgWJAhLCfOjM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Knowledge+Management&rft.atitle=Knowledge+sharing+in+open+source+software+communities%3A+motivations+and+management&rft.au=Iskoujina%2C+Zilia%3BRoberts%2C+Joanne.&rft.aulast=Iskoujina&rft.aufirst=Zilia&rft.date=2015-07-01&rft.volume=19&rft.issue=4&rft.spage=791&rft.isbn=&rft.btitle=&rft.title=Journal+of+Knowledge+Management&rft.issn=13673270&rft_id=info:doi/10.1108%2FJKM-10-2014-0446","Open source software; Online communities; Motivation; Community; Data analysis; Qualitative research; Business And Economics--Management; Collaboration; Virtual communities; Open source; Online community; Software; Open-source software; Product development; Management; Quantitative research; Factor analysis; Regression analysis; Knowledge management; Knowledge sharing; Project management; Public domain; Surveys & questionnaires; Research & development--R&D; Literature reviews; Correlation analysis; Explicit knowledge; Open source software communities; Open source software projects; Tacit knowledge; Test procedures; Work environment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper inductively derives a framework for understanding participation from the perspective of the individual software developer based on data from two software communities with different governance structures. In both communities, a need for software-related improvements drives initial participation. The majority of participants leave the community once their needs are met, however, a small subset remains involved. For this set of developers, motives evolve over time and participation becomes a hobby. These hobbyists are critical to the long-term viability of the software code: They take on tasks that might otherwise go undone and work to maintain the simplicity and modularity of the code. Governance structures affect this evolution of motives. Implications for firms interested in implementing hybrid strategies designed to combine the advantages of open source software development with proprietary ownership and control are discussed.

The notion of the OS business model is discussed in the light of a substantial body of theoretical literature concerning strategic management and the economics of innovation, as well as specialized literature on OS. Empirical evidence based on a survey of 146 Italian software firms shows that firms have adapted to an environment dominated by incumbent standards by combining the offering of proprietary and OS software under different licensing schemes, thus choosing a hybrid business model. The paper examines the determinants of the degree of openness toward OS and discusses the stability of hybrid models in the evolution of the industry.

This survey-based study, conducted with 402 active LUG members representing 191 different LUGs from 23 countries and employing structural equation modeling methodology, supports the proposed model. Furthermore, we find that the Linux user's experience level moderates the extent of the LUG's social influence and its impact on the user's participation.

Enterprises that are still discouraged by the task of converting existing software might find that modernization building blocks can make that task easier. Adapting or converting to OSS need not be overwhelming as this case study shows. There are many ways to use OSS in the enterprise, ranging from a few components to single applications, suites of related applications, and complete enterprise solutions.With such a diversity of applications, OSS use is even more attractive, yet it is not a trivial undertaking. The logistics of moving to OSS need not be daunting, however, if the organization considers the entire modernization plan, considers what various application types require, and does not undertake too much conversion at once.","2007-08","2025-04-25 16:59:15","2025-04-25 16:59:15","","28-33","","4","9","","","","","","","","","","English","","","ABI/INFORM Global","206314923","","","Place: Washington Publisher: IEEE Computer Society","","; ","https://media.proquest.com/media/hms/OBJ/EotNT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzMjY4NjIJMjA2MzE0OTIzOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDcvMDcvMDFyCjIwMDcvMDgvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=AI26cIb%2B2CTO0QHZuI0xHTHgLr8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IT+Professional+Magazine&rft.atitle=Open+Source+Software%3A+Is+It+Worth+Converting%3F&rft.au=Laplante%2C+Phillip%3BGold%2C+Anthony%3BCostello%2C+Thomas.&rft.aulast=Laplante&rft.aufirst=Phillip&rft.date=2007-07-01&rft.volume=9&rft.issue=4&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=IT+Professional+Magazine&rft.issn=15209202&rft_id=info:doi/10.1109%2FMITP.2007.72","Open source software; Open source; Software engineering; Software; Open-source software; Linux; Documentation; Software development; Software quality; Interoperability; 5240:Software & systems; Public domain; 2500:Organizational behavior; Innovations; Organization theory; United States--US; Engineering; 9190:United States; 2310:Planning; Open; Corporate planning; Modernization; Software modernization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

South Africa is Botswana's neighbor and both countries are leading economies in Africa. Design/methodology/approach - The paper draws on a survey that was carried out in information communication technology (ICT)-intensive government ministries in Botswana in May 2008. The study sought to establish availability of policy framework, level of usage of open source software, government support, motivations for implementing open source software in government, availability of skills, attitude of it managers in government toward open source software and challenges of open source software deployment in the public sector. The population of the study consisted of information technology (IT) managers who were purposively selected from ICT-intensive government ministries and interviewed. The study was extended to cover South Africa through review of literature on the same issues as those studied in Botswana. Findings - Compared with other countries in developed and developing countries including South Africa, there is limited use of open source software in the public sector in Botswana. However, IT managers in government of Botswana demonstrate a positive attitude toward open source software, and seem to have adequate understanding of its potential benefits. Comparatively, South African government provides support for harnessing open source software; awareness among top government officials is high and attitude toward open source software seems positive; skills are generally available and hardly any challenges of using open source software were identified. Research limitations/implications - This study was limited to purposively selected government ministries which are ICT-intensive in Botswana, while for South Africa, the study was based on secondary sources of data and focused on deployment of open source software in government agencies. Practical implications - Despite the increasing deployment of open source software in government across the world, the Botswanan government is yet unlikely to put in place an enabling open source software policy to harness the potential of the Software. Originality/value - Open source software deployment in government across the world is gaining momentum purportedly to enhance universal access, reduce costs associated with commercial software bridge the digital divide, grow indigenous IT skills, etc. Botswana and South Africa are the economic frontline states in Africa, and their leadership role in this matter among counterparts on the African continent is pertinent.

A key paradox of the global Internet is that it allows individual and collective decision making to co-exist with each other. Open source software (OSS) communities are a globally accelerating phenomenon. OSS refers to groups of programs that allow the free use of the software and further the code sharing to the general and corporate users of the software. The combination of private provision and public knowledge and software, and the seeming paradox of economic versus social motivations have stimulated a wide debate between researchers and policymakers. In this article, we analyze OSS communities from the viewpoint of ""intrinsic motivation,"" knowledge creation, and collective Internet governance. We believe that the growth of global OSS has fundamental implications for business ethics and the governance of the global Internet in the twenty-first century.

For this reason, this work aims to explore some of the effects of participation in a virtual brand community on consumer behaviour. The paper proposes the positive effects of participation in a virtual community on both consumer trust and loyalty to the product, brand or organisation around which the community is developed. In addition, it also proposes a positive effect of trust on consumer loyalty. After the validations of measurement scales, the hypotheses are contrasted through structural modelling. The data, obtained through a web survey using members of several free software virtual communities, show that participation in the activities carried out in a virtual community may foster consumer trust and loyalty to the mutual interest of the community (the free software in this case). In addition, the study also found a positive and significant effect of consumer trust on loyalty.","2007","2025-04-25 16:59:16","2025-04-25 16:59:16","","775-792","","6","31","","","","","","","","","","English","","","ABI/INFORM Global","194497941","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/FZrPT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNzE2MzIJMTk0NDk3OTQxOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDcvMTEvMDFyCjIwMDcvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=UdBSJueYZxEVhjUmemvKTzm2iOg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=The+impact+of+participation+in+virtual+brand+communities+on+consumer+trust+and+loyalty%3A+The+case+of+free+software&rft.au=Casal%C3%B3%2C+Luis%3BFlavi%C3%A1n%2C+Carlos%3BGuinal%C3%ADu%2C+Miguel.&rft.aulast=Casal%C3%B3&rft.aufirst=Luis&rft.date=2007-11-01&rft.volume=31&rft.issue=6&rft.spage=775&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/10.1108%2F14684520710841766","Communication; Social interaction; Community; Qualitative research; Studies; Computers--Internet; Virtual communities; Participation; Software; Consumer behavior; Group Dynamics; Consumers; Brand loyalty; Virtual community; Internet; Trust; Computer Mediated Communication; Social networks; Loyalty; Surveys & questionnaires; 9130:Experimental/theoretical; 7100:Market research; 5250:Telecommunications systems & Internet communications; Community Relations; Brand; Brand community; Community Involvement; Consumer behaviour; Customer retention; Electronic Mail; Information Sources; Literature Reviews; Virtual networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data.Design/methodology/approachThe methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample.FindingsThe quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning.Research limitations/implicationsThe results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning.Practical implicationsThis study allows the authors to highlight two main practical contributions for OSSCs’ directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables.Originality/valueThis paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).","2017","2025-04-25 16:59:16","2025-04-25 16:59:16","","534-554","","4","30","","","","","","","","","","English","","","ABI/INFORM Global","1915493022","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/FHmT7?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=U6iPPuKsbLfn2Ug5EJ3Vyj54%2B2w%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Enterprise+Information+Management&rft.atitle=How+do+Open+Source+software+companies+respond+to+institutional+pressures%3F+A+business+model+perspective&rft.au=Mouakhar%2C+Khaireddine%3BTellier%2C+Alb%C3%A9ric.&rft.aulast=Mouakhar&rft.aufirst=Khaireddine&rft.date=2017-07-01&rft.volume=30&rft.issue=4&rft.spage=534&rft.isbn=&rft.btitle=&rft.title=Journal+of+Enterprise+Information+Management&rft.issn=17410398&rft_id=info:doi/10.1108%2FJEIM-05-2015-0041","Open source software; Library And Information Sciences; Collaboration; Open source; Open-source software; Business model; Business models; Public domain; 51321:Software Publishers; Software industry; Strategic management; Value creation; Empirical analysis; Qualitative analysis; 14.14:COMMUNICATIONS AND INFORMATION TECHNOLOGY - SOFTWARE; Accommodation; Aggregates; Business competition; Quantitative analysis; Social activism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hierarchical configurations have been used to structure processes, overcome resistance and get things done. But is deliberate change also possible without formal structures and hierarchical influence? Design/methodology/approach This longitudinal, qualitative study investigates an open-source software (OSS) community named TYPO3. This case exhibits no formal hierarchical attributes. The study is based on mailing lists, interviews and observations. Findings The study reveals that deliberate change is indeed achievable in a non-hierarchical collaborative OSS community context. However, it presupposes the presence and active involvement of informal change agents. The paper identifies and specifies four key drivers for change agents' influence. Originality/value The findings contribute to organisational analysis by providing a deeper understanding of the importance of leadership in making deliberate change possible in non-hierarchical settings. It points to the importance of ""change-by-conviction"", essentially based on voluntary behaviour. This can open the door to reducing the negative side effects of deliberate change also for hierarchical organisations.","2017","2025-04-25 16:59:16","2025-04-25 16:59:16","","346-374","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1896276387","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/PFT/1/00TF7?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyOTM2NjIKMTg5NjI3NjM4NzoNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDE3LzAzLzAxcgoyMDE3LzA0LzMwegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAg9BcnRpY2xlfEZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=VFG1%2F%2Fkpv60j9SnR5Iuidh4BRhA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Organizational+Analysis&rft.atitle=Deliberate+change+without+hierarchical+influence%3F+The+case+of+collaborative+OSS+communities&rft.au=N%C3%B8rskov%2C+Sladjana%3BKesting%2C+Peter%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=N%C3%B8rskov&rft.aufirst=Sladjana&rft.date=2017-03-01&rft.volume=25&rft.issue=2&rft.spage=346&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Organizational+Analysis&rft.issn=19348835&rft_id=info:doi/10.1108%2FIJOA-08-2016-1050","Science; Open source software; Interviews; Leadership; Qualitative research; Business And Economics--Management; Collaboration; Participation; Open-source software; Linux; Public domain; Freeware; Collaborative; Reputations; Strategic management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The projects and developers co-evolve in an ecosystem. To keep healthy evolution of such OSS ecosystems, there is a need of attracting and retaining developers, particularly project leaders and core developers who have major impact on the project and the whole team. Therefore, it is important to figure out the factors that influence developers' chance to evolve into project leaders and core developers. To identify such factors, we conducted a case study on the GNOME ecosystem. First, we collected indicators reflecting developers' subjective willingness to contribute to the project and the project environment that they stay in. Second, we calculated such indicators based on the GNOME dataset. Then, we fitted logistic regression models by taking as independent variables the resulting indicators after eliminating the most collinear ones, and taking as a dependent variable the future developer role (the core developer or project leader). The results showed that part of such indicators (e.g., the total number of projects that a developer joined) of subjective willingness and project environment significantly influenced the developers' chance to evolve into core developers and project leaders. With different validation methods, our obtained model performs well on predicting developmental core developers, resulting in stable prediction performance (0.770, F-value).","2017-03","2025-04-25 16:59:16","2025-04-25 16:59:16","","396-414","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","1875688833","","","Place: Beijing Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/xdbAX?_a=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&_s=ikTHU0ejKcL%2BRbadEjSt0YQrJag%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Computer+Science+and+Technology&rft.atitle=Developer+Role+Evolution+in+Open+Source+Software+Ecosystem%3A+An+Explanatory+Study+on+GNOME&rft.au=Cheng%2C+Can%3BLi%2C+Bing%3BLi%2C+Zeng-Yang%3BZhao%2C+Yu-Qi%3BLiao%2C+Feng-Ling.&rft.aulast=Cheng&rft.aufirst=Can&rft.date=2017-03-01&rft.volume=32&rft.issue=2&rft.spage=396&rft.isbn=&rft.btitle=&rft.title=Journal+of+Computer+Science+and+Technology&rft.issn=10009000&rft_id=info:doi/10.1007%2Fs11390-017-1728-9","Science; Open source software; Computers; Leadership; Studies; Collaboration; Open source; Computer science; Software; Regression analysis; Evolution; Case studies; Software development; Software ecosystem; Public domain; Software Projects; Developer; Dependent variables; Independent variables; Indicators; Logistic regression; Performance prediction; Regression models; Research & development--R&D; United States--US","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

HFOSS also integrates two volunteer-rich communities that have much in common: the humanitarian community and the open source community.

As legal entities, OSSF help communities attain their long-term goals, hold community assets, provide resources to communities, and balance interests amongst different stakeholders. When OSS started to draw more business interests, commercial companies became involved with open source communities. The emergence of OSSF provides a good platform and opportunities for companies to exert their influence in a more direct way. This article summarizes the author's recent research regarding the relationships between company involvement, governance, revenue, and OSSF. Key findings in the research reported in this article contribute to the existing literature on open source and non-profits.

OSS continues to gain momentum worldwide due to its low entry barrier, high quality and customizability. More information technology (IT) decision makers are favoring OSS over traditional packaged software as it becomes more aligned with organizational needs. OSS is now part of the IT mainstream, supporting many of the world's largest companies and government institutions. The role of OSS continues to expand, from deep within the infrastructure to the key applications that drive a business. Proprietary software vendors have sales and marketing teams to inform their customer base and provide detailed responses to RFIs (Requests for Information), RFPs (Requests for Proposal) or RFQs (Requests for Quotation). While many open source products and projects do not measure up to the EQS Directory standards, they can still be used in certain situations.","2008-05","2025-04-25 16:59:16","2025-04-25 16:59:16","","17-20","","","","","","","","","","","","","English","","","ABI/INFORM Global","1694724631","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/kteiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk0NzI0NjMxOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDgvMDUvMDFyCjIwMDgvMDUvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=sYjYBZWb6e6Qa62AdI4CyHRsu4c%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=OSS+FOR+CORPORATE+IT&rft.au=von+Rotz%2C+Bruno.&rft.aulast=von+Rotz&rft.aufirst=Bruno&rft.date=2008-05-01&rft.volume=&rft.issue=&rft.spage=17&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Infrastructure; Information technology; Business And Economics; Open source; Open-source software; Software packages; Software design; Trends; Software development; Software quality; 5240:Software & systems; Public domain; United States--US; 9190:United States; Corporation; Customer relationship management; Ratings & rankings; Request for proposal","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open sourcing software developments means sharing technology and resources with communities worldwide to help eliminate the digital divide, create economic opportunity, and support equal access to technology. Therefore, a methodological approach is needed to assess properly the performance and the value generation potential and to put such measure into organizational reports. International financial reporting framework is checked over conditions to allow value recognition of open sourced assets. Linux kernel development value is estimated to reflect worth of open source developments despite absence of book value due to inexistence of a single cost source. Several attempts to estimate a valuation of open source software have been performed previously. However, this study is the first to judge suitability of accounting framework to report on this value. The main finding is that open sourced assets do not fully accomplish conditions to be included in financial reports. We seek to stimulate academic and professional debate about the pursuit of valuation of a large and efficient ecosystem of software innovation, freely available to society.","2013-04","2025-04-25 16:59:16","2025-04-25 16:59:16","","3-16","","1","3","","","","","","","","","","Portuguese","","","ABI/INFORM Global","1692031926","","","Place: Senhor do Bonfim Publisher: Universidade do Estado da Bahia (UNEB) - Departamento de Ciências Humanas","","; ","https://media.proquest.com/media/hms/ORIG/1/Z65xB?_a=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%3D%3D&_s=%2FGKZ1afCSon8%2FPZtrUCYGuUXSwc%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revista+de+Gest%C3%A3o%2C+Finan%C3%A7as+e+Contabilidade&rft.atitle=VALUATION+OF+OPEN+SOURCE+SOFTWARE%3A+HOW+DO+YOU+PUT+A+VALUE+ON+FREE%3F&rft.au=Garc%C3%ADa-Garc%C3%ADa%2C+Jesus%3BMar%C3%ADa+Isabel+Alonso+de+Magdaleno.&rft.aulast=Garc%C3%ADa-Garc%C3%ADa&rft.aufirst=Jesus&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=3&rft.isbn=&rft.btitle=&rft.title=Revista+de+Gest%C3%A3o%2C+Finan%C3%A7as+e+Contabilidade&rft.issn=&rft_id=info:doi/","Open source software; Business And Economics; open source software; Models; Statistical analysis; 5240:Software & systems; 9130:Experimental/theoretical; 4120:Accounting policies & procedures; accounting standards; Accounting standards; Financial reporting; Intangible assets","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-04-25 16:59:17","2025-04-25 16:59:17","","119-139","","1","39","","","","","","","","","","English","","","ABI/INFORM Global","1655249846","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/Q0uKV?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=R25kjKINZviPGbD5HDw%2FPkyDgc4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Online+Information+Review&rft.atitle=Raising+the+general+public%27s+awareness+and+adoption+of+open+source+software+through+social+Q%26amp%3BA+interactions&rft.au=Choi%2C+Namjoo%3BYi%2C+Kwan.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-01-01&rft.volume=39&rft.issue=1&rft.spage=119&rft.isbn=&rft.btitle=&rft.title=Online+Information+Review&rft.issn=14684527&rft_id=info:doi/","Open source software; Motivation; Qualitative research; Studies; Computers--Internet; Open source; Open-source software; Usability; Research; Success; Intention; Cybersecurity; Content analysis; Information science; 5240:Software & systems; Public domain; Surveys & questionnaires; Computer Software; 9130:Experimental/theoretical; Altruism; Community Relations; Literature Reviews; Ideology; Information exchange; Information needs; Information Needs; Jargon; Online Surveys; Self Efficacy; Yahoo!

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lock-in, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-04-25 16:59:17","2025-04-25 16:59:17","","7-12","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473085","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/nB2HV?_a=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%3D%3D&_s=NZyVa1ltHqsMgZMPP3rqT9Il6aw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=Code+Forking%2C+Governance%2C+and+Sustainability+in+Open+Source+Software&rft.au=Nyman%2C+Linus%3BLindman%2C+Juho.&rft.aulast=Nyman&rft.aufirst=Linus&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=7&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Business And Economics; Open source; open source software; Software; innovation; Open-source software; sustainability; Sustainability; Social; Software development; Public domain; Code; code forking; Freeware; planned obsolescence","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-04-25 16:59:17","2025-04-25 16:59:17","","32-39","","1","3","","","","","","","","","","English","","","ABI/INFORM Global","1614473053","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/y42HV?_a=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%3D%3D&_s=Nm%2Bs3gRvmsj2phuAD0rARjfdGCg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=The+Evolving+Role+of+Open+Source+Software+in+Medicine+and+Health+Services&rft.au=Ingram%2C+David%3BSevket+Seref+Arikan.&rft.aulast=Ingram&rft.aufirst=David&rft.date=2013-01-01&rft.volume=3&rft.issue=1&rft.spage=32&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Research & development--R&D; Open standard; Records management; 62211:General Medical and Surgical Hospitals; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within the context of a knowledge-based economy, this sort of approach appears exemplary for a growing number of industrial activities in which the amount of knowledge that has to be mastered is too large for a single agent, however powerful. Considering knowledge as a mutual resource requires a rethinking of the value chain concept, since cash flow is derived from use of the knowledge base (services, complementary products), not from the knowledge itself. In a classical industrial economics perspective, this reshaping of the value chain must be analyzed not only at the global ecosystem level (who produces what, between firms and universities, users and producers, etc.), but also at the industrial level (once the industry's role has been identified, how does it organize itself?). In this article, we argue for a more structured and global analysis, based on the tools of industrial economics, and thus starting from the basic conditions of the computer market and of the buyers' competence in software development (the ""dominant user's skill"").","2011","2025-04-25 16:59:17","2025-04-25 16:59:17","","39-64","","136","","","","","","","","","","","English","","","ABI/INFORM Global","1586117409","","","Place: Brussels Publisher: Editions De Boeck Superieur","","; ","https://media.proquest.com/media/hms/OBJ/zKIGV?_a=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%3D%3D&_s=ZcfgsSodIWlaAtubQXMmN1s8MVw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revue+d%27%C3%89conomie+Industrielle&rft.atitle=FLOSS+IN+AN+INDUSTRIAL+ECONOMICS+PERSPECTIVE&rft.au=Jullien%2C+Nicolas%3BZimmermann%2C+Jean-Beno%C3%AEt.&rft.aulast=Jullien&rft.aufirst=Nicolas&rft.date=2011-10-01&rft.volume=&rft.issue=136&rft.spage=39&rft.isbn=&rft.btitle=&rft.title=Revue+d%27%C3%89conomie+Industrielle&rft.issn=01543229&rft_id=info:doi/","Open source software; Computers; Information technology; Open-source software; Competition; Operating systems; Economics; Software development; Organizational behavior; Computer industry; 5240:Software & systems; 2500:Organizational behavior; 9175:Western Europe; Industrial economics; Value chain; 1130:Economic theory; Competitive advantage; Free and open-source software; 33411:Computer and Peripheral Equipment Manufacturing; Business And Economics--Production of Goods And Services; Floss; France; Computer based modeling; Expert systems; Generic products; Industrial organization; Knowledge base","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Specifically, I posit that within an organization 's IT department, OSS opinion leaders should have different social network profiles in terms of degree of centrality, betweenness, closeness and in-degree centrality from their peers who are not OSS opinion leaders. I also postulate that differences exist in the two groups' demographic characteristics such as age, educational level, tenure in organization, position in organization, and personality profiles such as openness and extraversiOn. A field survey using Social Network Analysis technique was carried out to test the hypotheses. Based on the findings, important theoretical and practical implications are identified.","2014","2025-04-25 16:59:17","2025-04-25 16:59:17","","1-10","","4","54","","","","","","","","","","English","","","ABI/INFORM Global","1548674998","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","; ","https://media.proquest.com/media/hms/OBJ/dDdCV?_a=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&_s=O3Shm2d9ZOwTn3CGWIOKZPqONhE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=SOCIAL+CAPITAL+CHARACTERISTICS+OF+OPEN+SOURCE+SOFTWARE+OPINION+LEADERS&rft.au=Yan%2C+Li.&rft.aulast=Yan&rft.aufirst=Li&rft.date=2014-07-01&rft.volume=54&rft.issue=4&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/","Open source software; Computers; Leadership; Communication; Social network analysis; China; Social capital; Studies; Open source; Open-source software; Technology adoption; Influence; Power; Social networks; 9130:Experiment/theoretical treatment; Public domain; 9179:Asia & the Pacific; 1220:Social trends & culture; Employees; Perceptions; 5220:Information technology management; Opinion leadership; Communications networks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is a complicated social process to understand. OSS is a multi-faceted phenomenon including code, a licensing structure, a community, development best practices, a method of diffusion. However, the current OSS collaborative researches place too much emphasis on collaborative behaviors, but ignore the study on collaborative process. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and level of collaboration between collaborators. Based on the definition of three types of contact behavior, this paper presents an approach to measuring the contact relationship intensity. Based on introducing and improving TF-IDF (term frequency-inverse document frequency), this paper presents the methods for calculating tag weights and work similarity between collaborators. Finally, by evaluating the model using data from the OSS website www.Codeplex .com, we verify that our model outperforms conventional models in both describing and forecasting collaborative behavior.

In particular, this study uses functional data analysis to uncover the development patterns of open source software projects in terms of effectiveness and activity levels. Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects. Lastly, our findings remark the importance of fostering active communities for superior effectiveness and long-term survival of the community.

Practitioner, donor, and academic interest in this strategy is on the rise, and successful CBNRM organizations are experiencing internal and external pressures to help ""transfer"" their knowledge and experiences to other contexts and scales. If organized through the traditional top-down diffusion of innovation approach, many barriers to CBNRM transfer exist, beginning with organizational costs that may outweigh potential benefits. However, reframed as a more ""open"" and emergent process, the burdens of transfer may be reduced and benefits increased. We draw on an analogy from the Open Source Software (OSS) movement to suggest an organizational rationale for exchange and principles such as ""porting,"" the ""kernel,"" ""copyleft,"" and ""forking"" that can guide CBNRM and for community-based organizations challenged to share their approach to conservation.

Different approaches for introducing usability activities into SW development have not yet been evaluated with respect to open source software (OSS). This paper tests the introduction of usability activities through four empirical case studies in the OSS development context. Case studies were carried out using four OSS projects that were not commercially supported. Empirical analysis suggests that usability specialists should become members of the OSS community, but, at the same time, should keep an objective view. The usability activities had substantially more impact when specialists introduced and carried them out as fellow members of the OSS community than as usability consultants from outside the community. The importance of management commitment for usability activities is discussed in the OSS context. The challenge of adapting usability and OSS development philosophies together should be researched further.

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-04-25 16:59:18","2025-04-25 16:59:18","","156-187","","2","25","","","","","","","","","","English","","","ABI/INFORM Global","1018105738","","","Place: West Linn Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/wxbVU?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgQzOTgzMgoxMDE4MTA1NzM4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTIvMDQvMDFyCjIwMTIvMDYvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCEVJlcG9ydHxDYXNlIFN0dWR50gIBWfICAPoCAU6CAwNXZWKKAxxDSUQ6MjAyNTAyMjcwMjA0MDc2MTM6NjY5NzMy&_s=5S7bea3gFvTMEM%2F05u2ZFWpFKOA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Information+Technology+%26+People&rft.atitle=Adoption+of+free%2Flibre+open+source+software+in+public+organizations%3A+factors+of+impact&rft.au=Rossi%2C+Bruno%3BRusso%2C+Barbara%3BSucci%2C+Giancarlo.&rft.aulast=Rossi&rft.aufirst=Bruno&rft.date=2012-04-01&rft.volume=25&rft.issue=2&rft.spage=156&rft.isbn=&rft.btitle=&rft.title=Information+Technology+%26+People&rft.issn=09593845&rft_id=info:doi/10.1108%2F09593841211232677","Open source software; Qualitative research; Information technology; Collaboration; Open source; Open-source software; Technology; Case studies; Technology adoption; Migration; Adoption; Case study; 5240:Software & systems; Public domain; Innovations; Public sector; 9130:Experimental/theoretical; Open standards; Cost control; Business process re-engineering; Disruptive innovation; Environmental factor; Library And Information Sciences--Computer Applications; Software services","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper aims to illustrate that if Free and/or Open Source Software is to be used as a building block to bridge the ""digital divide"" a more social and environmental perspective, which embraces the philosophy behind the software, needs to complement the technical perspective. The human environmental model is presented as a useful alternative which, if embraced, can inform more holistic information and communication technology (ICT) policies. Design/methodology/approach - Through a review of diffusion of innovations models an alternative diffusion framework is described and applied to an interpretive open source case study in South Africa. Findings - Contemporary diffusion and innovation models are narrowly focused on IT as a purely technological linear phenomenon. This perspective also underlies many ICT policies. A more socio-technical adoption model can assist in providing a more holistic approach to ICT policy development. Originality/value - The application of a new innovation model, the human environmental model, to ICT policy provides a holistic framework in which the complexity of the innovation process can be reflected in policy. Such an approach to ICT policy formulation will assist with broadening the perspective of policy makers from IT as a technical solution to IT as part of a socio-technical solution and recognise the duality of the innovation process.","2010","2025-04-25 16:59:19","2025-04-25 16:59:19","","108-123","","1","8","","","","","","","","","","English","","","ABI/INFORM Global","1011911286","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/mpsTU?_a=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&_s=8%2FidtJ78c4ZfaFFFTieuCb%2F0c%2BA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.atitle=A+human+environmentalist+approach+to+diffusion+in+ICT+policies%3A+A+case+study+of+the+FOSS+policy+of+the+South+African+Government&rft.au=Weilbach%2C+Lizette%3BByrne%2C+Elaine.&rft.aulast=Weilbach&rft.aufirst=Lizette&rft.date=2010-01-01&rft.volume=8&rft.issue=1&rft.spage=108&rft.isbn=&rft.btitle=&rft.title=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.issn=1477996X&rft_id=info:doi/10.1108%2F14779961011024837","Philosophy; Information technology; Studies; Open-source software; Diffusion; Organizational change; Economic; Technological change; Innovations; Perceptions; Business process reengineering; Communication channels; Departments; Developing countries--LDCs; Diffusion of innovations; Environmental modeling; Environmentalists","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In more recent years, FOSS is becoming an increasingly important element in strategies for development and implementation of information and communication technologies also in developing countries. Mainstream research on FOSS has catered to the underlying principles or freedom, open organizational forms, and on its economical aspects. The purpose of this paper is to shed new light on the actual consequences of FOSS, often left in the background. Design/methodology/approach - The paper examines where FOSS principles' assumptions are likely to be more evident: in contexts of developing countries, which are geographically and organizationally far from the original environment of FOSS. A mixed methodology characterizes this work: quantitative and qualitative methods bring readers' attention to unusual empirical settings and downplayed organizational processes of information technology (IT) implementation and adoption. Findings - The consequences of FOSS on IT implementation and actual use are ambivalent. It is argued that FOSS adoption does not happen spontaneously, neither by decree, and that the relevance of open technologies as public goods remains in the different role of local actual technical and organizational capabilities, and environment conditions. Originality/value - Such a focus complements existing studies on the economical relevance of FOSS, which are not the focus of this paper.","2010","2025-04-25 16:59:19","2025-04-25 16:59:19","","42-56","","1","8","","","","","","","","","","English","","","ABI/INFORM Global","1011911065","","","Place: Bingley Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/6lsTU?_a=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%3D%3D&_s=%2BFbGY6VK%2BngJpAtQmuKRq7ybKEA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.atitle=Free+and+Open+Source+Software+in+developing+contexts%3A+From+open+in+principle+to+open+in+the+consequences&rft.au=Miscione%2C+Gianluca%3BJohnston%2C+Kevin.&rft.aulast=Miscione&rft.aufirst=Gianluca&rft.date=2010-01-01&rft.volume=8&rft.issue=1&rft.spage=42&rft.isbn=&rft.btitle=&rft.title=Journal+of+Information%2C+Communication+%26+Ethics+in+Society&rft.issn=1477996X&rft_id=info:doi/10.1108%2F14779961011024800","Open source software; India; Politics; Philosophy; Decision making; Information technology; Studies; Open source; Software; Competition; Technology adoption; Influence; Costs; South Africa; Public domain; Economic; Technological change; Proprietary; Free and open-source software; Developing countries--LDCs; Developing country; Small & medium sized enterprises-SME; Computer literacy; Development strategies; Environmental impact; Information and communications technology; National security; Skill development; Skills","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted an abductive, computationally intensive study of eight OSS projects, using relational event modeling to analyze 1,169,489 actions covering 93 major software releases. The process of entrainment that we identify involves three task allocation mechanisms: (1) developer-issue inertia, (2) developer contribution frequency, and (3) issue popularity. Our analysis demonstrates that these mechanisms and the phases of the release cycle entrain each other. Before a major release, developers engage in a concentrated mobilization phase, whereby they democratize development activity and increasingly allocate community contributions to the set of issues related to the release. After a major release, the extended cleanup phase garners a greater share of development work from recently highly active developers and dilutes the activity of these developers across a wider range of issues. Our theorizing suggests that major releases constitute important events around which OSS communities self-organize and we characterize how this occurs. Our research contributes to theorizing on organizing in OSS communities by explaining how self-organizing task allocation interacts with release cycles through the mechanism of entrainment. We also contribute to the literature on entrainment by showing how it may unfold in the context of online peer production communities such as OSS.","2024-03","2025-04-25 16:59:48","2025-04-25 16:59:48","","67","","1","48","","","","","","","","","","English","","","ABI/INFORM Global","3076685766","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Entrainment+of+Task+Allocation+and+Release+Cycles+in+Open+Source+Software+Development&rft.au=Lindberg%2C+Aron%3BSchecter%2C+Aaron%3BBerente%2C+Nicholas%3BHennel%2C+Phil%3BLyytinen%2C+Kalle.&rft.aulast=Lindberg&rft.aufirst=Aron&rft.date=2024-03-01&rft.volume=48&rft.issue=1&rft.spage=67&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2023%2F16789","Open source software; Computers; Software; Software development; Optimization; Public domain; Resource allocation; Impact fees; Entrainment","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We investigated 355 F/OSS software package websites for the presence of codes of conduct and then analyzed these for diversity elements. Qualitative content analysis of the websites shows that less than 10% (28) of the analyzed websites had some type of community rules such as CoC. In-depth analysis of the CoCs demonstrated many discrepancies in the terminology, length, enforcement, and adoption of codes of conduct. To investigate the usage of these CoCs, we investigate five women-focused OSS discussion forums. This analysis shows the value of creating/adopting a CoC and the impact CoC can have on the participation of women. We also present the challenges in the usage and enforcement of CoCs as discussed by women of these forums. We conclude with recommendations for better enforcement of CoC and reflection on the ethical underpinnings of CoC as a tool to improve diversity and inclusion in OSS.","2022-06","2025-04-25 16:59:48","2025-04-25 16:59:48","","581-620","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2681285630","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/f2aON?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=ZpVx1S6wrFO46n7oTR4%2BxuUtGlY%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Software+Quality+Journal&rft.atitle=Codes+of+conduct+in+Open+Source+Software%26mdash%3Bfor+warm+and+fuzzy+feelings+or+equality+in+community%3F&rft.au=Singh%2C+Vandana%3BBongiovanni%2C+Brice%3BBrandon%2C+William.&rft.aulast=Singh&rft.aufirst=Vandana&rft.date=2022-06-01&rft.volume=30&rft.issue=2&rft.spage=581&rft.isbn=&rft.btitle=&rft.title=Software+Quality+Journal&rft.issn=09639314&rft_id=info:doi/10.1007%2Fs11219-020-09543-w","Open source software; Community; Open source; Online community; Software; Open-source software; Software packages; Diversity; Content analysis; Public domain; Freeware; Computers--Software; Multiculturalism & pluralism; Qualitative analysis; Websites; Community participation; Code of conduct; Diversity and inclusion; Enforcement; Gender and IT; Woman; Women in open source","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considering the characteristics of OSS development and management projects, operation performance measures for OSS project management will take an irregular fluctuation in the long term of operation, because several developer and many users are closely related to the maintenance of OSS. Also, OSS projects will heavily depend the environment of internet network. This paper focuses on the irregular fluctuation of operation performance measures for OSS project management. We apply the double jump diffusion process models to the noisy cases in the operation of OSS. In particular, the maintenance effort is estimated by the stochastic differential equation model in terms of OSS project management. Moreover, we propose the method of maintenance effort management based on the double jump diffusion process model considering the irregular fluctuation of performance for OSS projects. Thereby, it will be helpful for the OSS developers and managers to understand the maintenance effort status of OSS from the standpoint of OSS project management.

While we can attribute identified peripheral contributions (IPC) to specific individuals and OSS projects need them to succeed, one cannot trace back anonymous peripheral contributions (APC), and they can have both positive and negative ramifications for project development. Open platforms and managers face a challenging design choice in deciding whether to allow APC and for which tasks or what type of projects. We examine the impact that the ratio between APC and IPC has on OSS project performance. Our results suggest that the OSS projects perform the best when they contain a uniform anonymity level (i.e., they contain predominantly APC or predominantly IPC). However, our results also suggest that OSS projects have lower performance when the ratio between APC and IPC nears one (i.e., they contain close to the same number of APC and IPC). Furthermore, our results suggest that these results differ depending on the type of application that a project develops.

These offer an opportunity to evaluate the generalizability of the original study to projects of different sizes and amount of activity, yet similar otherwise to the project in the original study. Another extension is the use of an additional control variable, length of activity sequence, which proves to have substantial implications of the study’s focal relationships. We find that three out of the four projects we analyze support the findings of the original study as it pertains to four relationships in the original study: order variation and developer interdependencies, activity variation and developer interdependencies, order variation and development interdependencies, and development and developer interdependencies. We also discuss the implications of our findings, especially in cases where the replication results differ from those in the original study and offer suggestions for future research that can help advance this stream of research.","2020","2025-04-25 16:59:48","2025-04-25 16:59:48","","14","","","6","","","","","","","","","","English","","","ABI/INFORM Global","2499402545","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/P8BUI?_a=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%3D%3D&_s=de4bXNlJyrljqUKWItXwCZkugxk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=AIS+Transactions+on+Replication+Research&rft.atitle=Coordinating+Interdependencies+in+an+Open+Source+Software+Project%3A+A+Replication+of+Lindberg%2C+et+al.&rft.au=Bradley%2C+Randy%3BMockus%2C+Audris%3BMa%2C+Yuxing%3BZaretzki%2C+Russell%3BBichescu%2C+Bogdan.&rft.aulast=Bradley&rft.aufirst=Randy&rft.date=2020-01-01&rft.volume=6&rft.issue=&rft.spage=14&rft.isbn=&rft.btitle=&rft.title=AIS+Transactions+on+Replication+Research&rft.issn=&rft_id=info:doi/10.17705%2F1atrr.00057","Open source software; Open source; Software; Open-source software; Open Source Software; Coordination; Replication; Public domain; Sciences: Comprehensive Works; Software project management; Interdependencies","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Similarly, the software project life-spans are related to some internal or external characteristics. Analyzing the relations between these characteristics and the project life-span, may help developers, investors, and contributors to control the development cycle of the software project. The paper provides an insight on the project life-span for a free open source software ecosystem. The statistical analysis of some project characteristics in GitHub is presented, and we find that the choices of programming languages, the number of files, the label format of the project, and the relevant membership expressions can impact the life-span of a project. Based on these discovered characteristics, we also propose a prediction model to estimate the project life-span in open source software ecosystems. These results may help developers reschedule the project in open source software ecosystem.","2019-08","2025-04-25 16:59:48","2025-04-25 16:59:48","","1382-1391","","4","24","","","","","","","","","","English","","","ABI/INFORM Global","1992797490","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/z90ZA?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=iAyKXLD0BsgqHguvU0xopSL2oz8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Mobile+Networks+and+Applications&rft.atitle=A+Prediction+Model+of+the+Project+Life-Span+in+Open+Source+Software+Ecosystem&rft.au=Liao%2C+Zhifang%3BZhao%2C+Benhong%3BLiu%2C+Shengzong%3BJin%2C+Haozhi%3BHe%2C+Dayu%3BLiu%2C+Yang%3BZhang%2C+Yan%3BWu%2C+Jinsong.&rft.aulast=Liao&rft.aufirst=Zhifang&rft.date=2019-08-01&rft.volume=24&rft.issue=4&rft.spage=1382&rft.isbn=&rft.btitle=&rft.title=Mobile+Networks+and+Applications&rft.issn=1383469X&rft_id=info:doi/10.1007%2Fs11036-018-0993-3","Open source software; GitHub; Computers--Computer Networks; Open source; Software engineering; Software; Software ecosystems; Programming languages; Statistical analysis; Software ecosystem; Public domain; Freeware; Mathematical models; Software project management; Open source software ecosystem; Project characteristics; Project life-span","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By the turn of the millennium, FOSS developers had created the GNU/Linux operating system and several other significant products. FOSS is now a crucial part of the networked world, providing both software—for example web servers, desktop environments, and the FOSS-derived Android operating system that powers the majority of the world's mobile phones—and many of the programming languages in which that software is written. In one crucial respect (the production of the so-called ""kernel"" of the system) this effort stalled, and only the efforts of a project initiated in 1991 by Finnish student Linus Torvalds enabled the production of a complete operating system, usually simply called Linux.","2019-04","2025-04-25 16:59:49","2025-04-25 16:59:49","","655-657","","2","60","","","","","","","","","","English","","","ABI/INFORM Global","2273232637","","","Place: Baltimore Publisher: Johns Hopkins University Press","","; ","https://media.proquest.com/media/hms/PFT/1/ndmoA?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUzNTE4MjIKMjI3MzIzMjYzNzoNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDE5LzA0LzAxcgoyMDE5LzA0LzMwegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAgZSZXZpZXfSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Uin3nZ16VqS1y7MAHZFlsXycJTE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+and+Culture&rft.atitle=For+Fun+and+Profit%3A+A+History+of+the+Free+and+Open+Source+Software+Revolution+by+Christopher+J.+Tozzi+%28review%29&rft.au=Priestley%2C+Mark.&rft.aulast=Priestley&rft.aufirst=Mark&rft.date=2019-04-01&rft.volume=60&rft.issue=2&rft.spage=655&rft.isbn=&rft.btitle=&rft.title=Technology+and+Culture&rft.issn=0040165X&rft_id=info:doi/10.1353%2Ftech.2019.0058","Open source software; Russia; Open source; Software; Open-source software; Linux; Operating systems; Social; Free software; Software development; Programming languages; Servers; Public domain; Technological change; Freeware; Smartphones; Technology: Comprehensive Works; Books; France; Commercialization; Android; Finnish language; Mobile operating systems; Mobile phones; Monographs; Revolutions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considering the characteristics of OSS development and management projects, operation performance measures for OSS project management will take an irregular fluctuation in the long term of operation, because several developer and many users are closely related to the maintenance of OSS. Also, OSS projects will heavily depend the environment of internet network. This paper focuses on the irregular fluctuation of operation performance measures for OSS project management. We apply the double jump diffusion process models to the noisy cases in the operation of OSS. In particular, the maintenance effort is estimated by the stochastic differential equation model in terms of OSS project management. Moreover, we propose the method of maintenance effort management based on the double jump diffusion process model considering the irregular fluctuation of performance for OSS projects. Thereby, it will be helpful for the OSS developers and managers to understand the maintenance effort status of OSS from the standpoint of OSS project management. Also, we analyze actual data to show numerical examples of the proposed models with the characteristics considering noisy and jump of OSS projects.","2019-02","2025-04-25 16:59:49","2025-04-25 16:59:49","","1-16","","","","","","","","","","","","","English","","","ABI/INFORM Global","2182956604","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/7EsS8?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=QGw0xhrKfxFDDZrSZK8OfAWFV%2FU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Annals+of+Operations+Research&rft.atitle=Maintenance+effort+management+based+on+double+jump+diffusion+model+for+OSS+project&rft.au=Tamura%2C+Yoshinobu%3BYamada%2C+Shigeru.&rft.aulast=Tamura&rft.aufirst=Yoshinobu&rft.date=2019-02-01&rft.volume=&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=Annals+of+Operations+Research&rft.issn=02545330&rft_id=info:doi/10.1007%2Fs10479-019-03170-w","Open source software; Computers; Open-source software; Diffusion; Project management; Maintenance; Mathematical models; Differential equations; Operations research; Operation support systems; Double jump diffusion process model; Maintenance effort; Variation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we develop a multi-release software reliability model with consideration of the remaining software faults from previous release and the new introduced-faults (from newly added features). Additionally, dependent fault detection process is taken into account in this research. In particular, the detection of a new fault for developing the next release depends on the detection of the remaining faults from previous release and the detection of the new introduced-faults.

In this essay, I try to identify the ethical foundations of Stallmanism. I identify three major trends in Stallman’s thinking—libertarian, utilitarian, and communitarian—and I argue that none is sufficient to justify the radical claim that distributing non-Free software is always wrong (unless we accept extremely demanding ethical standards that Stallman himself does not consistently endorse). I recommend thinking of Stallmanism as an attempt to optimize the satisfaction of a number of core values, including freedom, cooperation, and happiness, and I stress the importance of connecting the Free software movement to other political struggles against oppression.","2018-09","2025-04-25 16:59:49","2025-04-25 16:59:49","","437-453","","3","31","","","","","","","","","","English","","","ABI/INFORM Global","1969424199","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/PFT/1/wWvp6?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=w0jz8lM3JLz46ko1Q3GYSOz5Sh4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Philosophy+%26+Technology&rft.atitle=Is+Proprietary+Software+Unjust%3F+Examining+the+Ethical+Foundations+of+Free+Software&rft.au=Rappaport%2C+Jesse.&rft.aulast=Rappaport&rft.aufirst=Jesse&rft.date=2018-09-01&rft.volume=31&rft.issue=3&rft.spage=437&rft.isbn=&rft.btitle=&rft.title=Philosophy+%26+Technology&rft.issn=22105433&rft_id=info:doi/10.1007%2Fs13347-017-0294-y","Open source software; Sociology; Ethics; Software; Free software; Freeware; Source code; Communitarianism; Computer ethics; Libertarianism; Stallman; Utilitarianism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Le second, celui de la déterritorialisation, présente les collectifs en ligne comme détachés de tout ancrage territorial. L’article montre la manière dont ces lieux communs habitent la culture du logiciel libre, en revenant aux origines de celle-ci au sein du AI Lab du MIT, en examinant l’influence exercée sur elle par la pensée cybernétique et en analysant le processus d’extension et de globalisation du free software. L’article développe également une critique de ces topoï, en montrant qu’ils contribuent à occulter la continuité entre les transformations du monde numérique et celles du reste de la société. La conclusion revient sur l’essor récent du mouvement maker, fortement influencé par le logiciel libre, et met en avant la persistance des enjeux liés à la matière et au territoire, y compris au sein de la culture numérique.Alternate abstract:This article questions two ideas that have become commonplace in digital culture, and particularly in free software culture. The first one is the idea that cyberspace is an immaterial (or informational) space, exhibiting properties that are radically distinct from the ones of the material world. The second one is the idea of deterritorialization, according to which online communities are indifferent to the geographical reality of the territory. The article explains how these commonplace assumptions pervade free software culture, tracing their history back to cybernetics and the AI Lab at the MIT, and analyzing the globalization of free software culture since the 1990s. It also criticizes these topoï that often conceal how the transformations of the digital world are intertwined with the transformations of society at large. The conclusion tackles the emergence of the maker movement (which is strongly tied to free software culture) and insists on the persistence of issues related to materiality and territory, even within digital culture.?","2018","2025-04-25 16:59:49","2025-04-25 16:59:49","","15-32","","1","20","","","","","","","","","","French","","","ABI/INFORM Global","2169345044","","","Place: Cachan Publisher: Lavoisier","","; ","https://media.proquest.com/media/hms/PFT/1/OHRF8?_a=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%3D%3D&_s=nNLe%2BrM1H5B2Uuyi2WPZVXtPtx0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Ge%CC%81ographie%2C+Economie%2C+Socie%CC%81te%CC%81&rft.atitle=Mati%26egrave%3Bre+et+territoire+dans+la+culture+du+logiciel+libre&rft.au=BROCA%2C+S%C3%A9bastien.&rft.aulast=BROCA&rft.aufirst=S%C3%A9bastien&rft.date=2018-01-01&rft.volume=20&rft.issue=1&rft.spage=15&rft.isbn=&rft.btitle=&rft.title=Ge%CC%81ographie%2C+Economie%2C+Socie%CC%81te%CC%81&rft.issn=1295926X&rft_id=info:doi/10.3166%2Fges.20.+2017.0027","free software; Software; cybernetics; Colonies & territories; Geography; Internet; Culture; Freeware; Globalization; Cybernetics; cybernétique; déterritorialisation; deterritorialization; Deterritorialization; immaterial; immatériel; logiciel libre; makers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Providing business strategy to benefit from volunteer developers for the purpose of contributing to existing projects, as well as initiating new OSS projects is of utmost significance for companies in that industry. Therefore, it is important to figure out how groups of volunteer developers are formed as new developers join existing projects, and it is even more important to investigate what causes these developers to initiate new projects. The authors investigate network structure as a causal factor for both new project initiation within a group (representing group innovation) as well as new developers joining existing projects within a group (representing group growth). The authors develop four hypotheses. 1. Intra-group coupling has a positive impact on group growth, 2. Inter-group coupling has a positive impact on group innovation, 3. Inter-group structural hole has a positive impact on group innovation, 4. There is a trade-off between the effects of inter-group structural hole and inter-group coupling on group innovation. The authors test these four hypotheses using data from OSS. Developers contributing to project tasks in groups other than their own can explore novel ideas for new project creation, because they can benefit from sharing knowledge, whereas developers contributing to project tasks inside their own group exploit ideas to improve those existing projects with better inside-group search possibility; and this demands more developers to join those group projects.","2017","2025-04-25 16:59:49","2025-04-25 16:59:49","","7-18","","1","15","","","","","","","","","","English","","","ABI/INFORM Global","2221307949","","","Place: Sumy Publisher: Business Perspectives Ltd.","","; ","https://media.proquest.com/media/hms/PFT/1/oiYA9?_a=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%3D%3D&_s=g3BXggG%2BVDYuRpLQ5xm2lAxzvJs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Problems+and+Perspectives+in+Management&rft.atitle=Network+tie+structure+causing+OSS+group+innovation+and+growth&rft.au=Behfar%2C+Stefan+Kambiz%3BTurkina%2C+Ekaterina%3BBurger-Helmchen%2C+Thierry.&rft.aulast=Behfar&rft.aufirst=Stefan&rft.date=2017-01-01&rft.volume=15&rft.issue=1&rft.spage=7&rft.isbn=&rft.btitle=&rft.title=Problems+and+Perspectives+in+Management&rft.issn=17277051&rft_id=info:doi/10.21511%2Fppm.15%281%29.2017.01","Open source software; Innovation; Business And Economics--Management; open source software; Hypotheses; Open-source software; Product development; Volunteers; Innovations; cluster management; network management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Free software is the best choice when the reduction of production costs is necessary; nevertheless, the quality of free software may vary. This paper probably does not include all of the free software, but tries to describe or mention at least the most interesting programs. The first part of this paper summarizes the essential knowledge about UAVs, including the fundamentals of flight mechanics and aerodynamics, and the structure of a UAV system. The second section generally explains the modelling and simulation of a UAV. In the main section, more than 50 free programs for the design, analysis, modelling, and simulation of a UAV are described. Although the selection of the free software has been focused on small subsonic UAVs, the software can also be used for other categories of aircraft in some cases; e.g. for MAVs and large gliders. The applications with an historical importance are also included. Finally, the results of the analysis are evaluated and discussed--a block diagram of the free software is presented, possible connections between the programs are outlined, and future improvements of the free software are suggested.","2016-09","2025-04-25 16:59:49","2025-04-25 16:59:49","","449-514","","3","23","","","","","","","","","","English","","","ABI/INFORM Global","1814065468","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/ORIG/1/jEVwB?_a=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%3D%3D&_s=6%2Fhz06HHcsUY4H4%2FGWDS3X1Vc9o%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Archives+of+Computational+Methods+in+Engineering&rft.atitle=A+Survey+of+Free+Software+for+the+Design%2C+Analysis%2C+Modelling%2C+and+Simulation+of+an+Unmanned+Aerial+Vehicle&rft.au=Vogeltanz%2C+Tom%C3%A1s.&rft.aulast=Vogeltanz&rft.aufirst=Tom%C3%A1s&rft.date=2016-09-01&rft.volume=23&rft.issue=3&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Archives+of+Computational+Methods+in+Engineering&rft.issn=11343060&rft_id=info:doi/10.1007%2Fs11831-015-9147-y","Design; Software; Analysis; Free software; Informatics; Model; Freeware; Aircraft; Simulation; 33641:Aerospace Product and Parts Manufacturing; Aerial; Mathematics--Computer Applications; Mechanics; Reynolds number; Unmanned aerial vehicle; Unmanned aerial vehicles; Vehicles; Velocity","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The rSCA package is efficient in dealing with both continuous and discrete variables, as well as nonlinear relationships between the variables. It divides the sample sets of dependent variables into different subsets (or subclusters) through a series of cutting and merging operations based upon the theory of multivariate analysis of variance (MANOVA). The modeling results are given by a cluster tree, which includes both intermediate and leaf subclusters as well as the flow paths from the root of the tree to each leaf subcluster specified by a series of cutting and merging actions. The rSCA package is a handy and easy-to-use tool and is freely available at http://cran.r-project.org/package=rSCA.

Passive users play a critical role in the adoption and diffusion of OSS, and we need more research to understand their behaviors and motivations. We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.","2015-08","2025-04-25 16:59:50","2025-04-25 16:59:50","","674-706","","8","16","","","","","","","","","","English","","","ABI/INFORM Global","1711618000","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/OBJ/QFcWV?_a=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&_s=Jhwwy9Bc3OJKaqpkwVBZtFS3DlI%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+the+Association+for+Information+Systems&rft.atitle=Loyalty%2C+Ideology%2C+and+Identification%3A+An+Empirical+Study+of+the+Attitudes+and+Behaviors+of+Passive+Users+of+Open+Source+Software&rft.au=Choi%2C+Namjoo%3BChengalur-Smith%2C+Indushobha%3BNevo%2C+Saggi.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2015-08-01&rft.volume=16&rft.issue=8&rft.spage=674&rft.isbn=&rft.btitle=&rft.title=Journal+of+the+Association+for+Information+Systems&rft.issn=15369323&rft_id=info:doi/","Open source software; Sociology; Identification; Information systems; Community; Studies; User behavior; Marketing; Virtual communities; Open source; Hypotheses; Open-source software; Consumer behavior; Research; Success; Computers--Information Science And Information Theory; Software development; Loyalty; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; 7100:Market research; Consciousness; Ideology; Usability testing; User","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Likewise, the economic theory of the firm, building on Ronald Coase's (1937) seminal analysis, has become an increasingly important field in economics and management. Despite this resurgence, there is still little connection between the entrepreneurship literature and the literature on the firm, both in academia and in management practice. This book fills this gap by proposing and developing an entrepreneurial theory of the firm that focuses on the connections between entrepreneurship and management. Drawing on insights from Austrian economics, it describes entrepreneurship as judgmental decision made under uncertainty, showing how judgment is the driving force of the market economy and the key to understanding firm performance and organization.","2015-03","2025-04-25 16:59:50","2025-04-25 16:59:50","","239-241","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","1652167838","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/HXZKV?_a=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&_s=C%2BtbN9CWyXwgb9UqOk4XQ%2FfgFZU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Entrepreneurship+and+Management+Journal&rft.atitle=Nicolai+J.+Foss%2C+Peter+G.+Klein%3A+Organizing+entrepreneurial+judgment%3A+a+new+approach+to+the+firm%3A+Cambridge+and+New+York%3A+Cambridge+University+Press%2C+2012+%28299+pages%29&rft.au=Howden%2C+David.&rft.aulast=Howden&rft.aufirst=David&rft.date=2015-03-01&rft.volume=11&rft.issue=1&rft.spage=239&rft.isbn=&rft.btitle=&rft.title=International+Entrepreneurship+and+Management+Journal&rft.issn=15547191&rft_id=info:doi/10.1007%2Fs11365-013-0276-1","Studies; Business And Economics--Management; Entrepreneurship; Economics; Entrepreneurs; Economic theory; Books; Austrian economics; Company; Court decisions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this, modelling was performed by considering the discrete aspects associated with transport systems with the continuous component of the carbon monoxide emissions from the fleet. The simulation models were constructed with the free and open-source software Ururau. The simulations searched to compare trade-offs of economic and environmental variables, in contrast to what is usually done in these types of systems, such as comparing economic variables with inventory variables. The results indicated that there is no direct relationship of proportionality between, for example, the delivery time and the total emissions produced by trucks.","2015-02","2025-04-25 16:59:50","2025-04-25 16:59:50","","27-42","","1","9","","","","","","","","","","English","","","ABI/INFORM Global","1650380574","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","; ","https://media.proquest.com/media/hms/OBJ/IAMKV?_a=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&_s=nZJkf43ERpwptag6xD22sgRw6fM%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Simulation&rft.atitle=Free+and+Open-Source+Software+for+sustainable+analysis+in+logistics+systems+design&rft.au=De+Assis+Rangel%2C+Jo%C3%A3o+Jos%C3%A9%3BCordeiro%2C+Anna+Christine+Azevedo.&rft.aulast=De+Assis+Rangel&rft.aufirst=Jo%C3%A3o&rft.date=2015-02-01&rft.volume=9&rft.issue=1&rft.spage=27&rft.isbn=&rft.btitle=&rft.title=Journal+of+Simulation&rft.issn=17477778&rft_id=info:doi/10.1057%2Fjos.2014.17","Open source software; Computers; Open-source software; Customers; Logistics; Free software; Public domain; Systems design; Simulation; 42311:Automobile and Other Motor Vehicle Merchant Wholesalers; Discrete-event simulation; Greenhouse gas emissions; Suppliers; Supply chain management; Trucks","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software--continue to--rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. Trust (i.e. full write-access) is 'backgrounded' by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.[PUBLICATION ABSTRACT]","2014-06","2025-04-25 16:59:50","2025-04-25 16:59:50","","157-169","","2","16","","","","","","","","","","English","","","ABI/INFORM Global","1527288756","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/m0B8V?_a=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&_s=LnBjH3HFlYs2ul1%2B0Dr9IIek9Ks%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Ethics+and+Information+Technology&rft.atitle=From+open-source+software+to+Wikipedia%3A+%27Backgrounding%27+trust+by+collective+monitoring+and+reputation+tracking&rft.au=de+Laat%2C+Paul+B.&rft.aulast=de+Laat&rft.aufirst=Paul&rft.date=2014-06-01&rft.volume=16&rft.issue=2&rft.spage=157&rft.isbn=&rft.btitle=&rft.title=Ethics+and+Information+Technology&rft.issn=13881957&rft_id=info:doi/10.1007%2Fs10676-014-9342-9","Open source software; Philosophy; Community; Social research; Collaboration; Open-source software; Wikipedia; Trust; Social networks; Public domain; Reputations; Reputation; Vandalism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value - This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them. Several implications for research and practice, and directions for future research are provided.","2014","2025-04-25 16:59:50","2025-04-25 16:59:50","","260-275","","2","32","","","","","","","","","","English","","","ABI/INFORM Global","1660948775","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/bsfLV?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=%2Fro5Oh0NZVnix0Jp8rf8XWaKix8%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Library+Hi+Tech&rft.atitle=The+application+profiles+and+development+characteristics+of+library+Open+Source+Software+projects&rft.au=Choi%2C+Namjoo.&rft.aulast=Choi&rft.aufirst=Namjoo&rft.date=2014-04-01&rft.volume=32&rft.issue=2&rft.spage=260&rft.isbn=&rft.btitle=&rft.title=Library+Hi+Tech&rft.issn=07378831&rft_id=info:doi/10.1108%2FLHT-09-2013-0127","Open source software; Community; Research methodology; Studies; Open source; Libraries; Open-source software; Licenses; Success; Data collection; Software development; Programming languages; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; Library And Information Sciences--Computer Applications; 51921:Libraries and Archives; Academic libraries; Institutional repositories; Archival description; Datasets; Integrated library systems--ILS; Integrated library systems-ILS; Internet resources","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-04-25 16:59:50","2025-04-25 16:59:50","","477-512","","4","34","","","","","","","","","","English","","","ABI/INFORM Global","1510748443","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/7E55V?_a=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%3D%3D&_s=czJcKyeF4MxHe1iEAX3BJW6CDu4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=International+Journal+of+Operations+%26+Production+Management&rft.atitle=Risk+of+adopting+mission-critical+OSS+applications%3A+an+interpretive+case+study&rft.au=Poba-Nzaou%2C+Placide%3BRaymond%2C+Louis%3BFabi%2C+Bruno.&rft.aulast=Poba-Nzaou&rft.aufirst=Placide&rft.date=2014-04-01&rft.volume=34&rft.issue=4&rft.spage=477&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Operations+%26+Production+Management&rft.issn=01443577&rft_id=info:doi/10.1108%2FIJOPM-03-2012-0117","Open source software; Information technology; Business And Economics--Management; Open source; Open-source software; Software packages; Product development; Risk management; Research; Case studies; Europe; Enterprise resource planning; Case study; 5240:Software & systems; 51321:Software Publishers; Software industry; Technological change; 9130:Experimental/theoretical; 9175:Western Europe; Manufacturing; Mission critical","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we propose and validate two antecedents of organizational investment in internal human capital in the context of OSS adoption. They are (1) firm-specificity of OSS human capital, which denotes the extent to which the internal OSS human capital is strongly tied to the organization and cannot be equally well applied in other organizations, and (2) learning-related scale, which reflects the extent to which the organizational cost of learning OSS can be spread by applying the knowledge gained to other projects and business functions within the organization. Survey data collected from 114 senior Information Technology (IT) managers and professionals indicates that these two factors are positively associated with the investment in cultivating internal OSS human capital.

OSS requires firms to rethink the processes that facilitate value creation and capture. The objective of this paper is to theorise how firms create and capture value from OSS. We derive a model from extant research and refine it through the study of three inter-organisational networks. The findings reveal how a firm's ability to access a value network of complementors is crucial for effective value creation and capture. Two types of networks are evident: a high-density network of familiar partners and a low-density network of multiple, often unfamiliar, partners. Leveraging these networks depends on the level of commitment, volume of knowledge exchange and the alignment of objectives among participant firms. Effective governance is revealed as critical for creating and capturing value within both types of network; and depends on both formal and informal mechanisms.

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-04-25 16:59:51","2025-04-25 16:59:51","","28-36","","12","2","","","","","","","","","","English","","","ABI/INFORM Global","1614473125","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/OBJ/Z92HV?_a=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%3D%3D&_s=ZdYPxuKLXrayO3DF6pRpkY8%2Bmbw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technology+Innovation+Management+Review&rft.atitle=An+Enterprise+Perspective+on+Customer+Value+Propositions+for+Open+Source+Software&rft.au=Shanker%2C+Aparna.&rft.aulast=Shanker&rft.aufirst=Aparna&rft.date=2012-12-01&rft.volume=2&rft.issue=12&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technology+Innovation+Management+Review&rft.issn=&rft_id=info:doi/","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors suggest that the new paradigm of open innovation may impact a firm's adaptability and responsiveness under conditions of environmental flux. However, extending innovation capacity by opening the innovation process poses major challenges for firms. The aims of this study are to explore the characteristics of open innovation activity and to contemplate the role of strategic flexibility in the design of business models based upon open innovation. Design/methodology/approach - The study draws upon a qualitative research approach through a longitudinal case study in the field of open source software (OSS). The empirical case illustrates how an OSS firm utilizes signals in its environment to flexibly alter its business model. Findings - A business model that embodies open innovation raises dilemmas between open and closed innovation paradigms. However, the authors' case highlights that an ambidextrous approach that combines market orientation with the principles of open innovation increases profitability, shortens time to market through effective market access, and enhances innovation capability. Research limitations/implications - The results have profound implications for industrial marketers, managers, management consultants and business educators. They can use the insights gleaned from this research to guide the development of business models that involve open innovation. The results indicate that firms involved in open innovation need reactive strategic flexibility to cope with the environmental diversity and variability. However, this study analyzes a single case in the field of OSS and one should be cautious when generalizing the findings. Originality/value - This paper improves the understanding of the relationship between flexibility and market orientation. It combines two areas that have previously been discussed separately, i.e. market orientation and open innovation.","2012","2025-04-25 16:59:51","2025-04-25 16:59:51","","1368-1388","","10","46","","","","","","","","","","English","","","ABI/INFORM Global","1048638938","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aSgaU?_a=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%3D%3D&_s=Kt9ntKr6OUvNoPbrVZ%2FKo1MpGrk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Marketing&rft.atitle=Strategic+flexibility+in+open+innovation+-+designing+business+models+for+open+source+software&rft.au=Rajala%2C+Risto%3BWesterlund%2C+Mika%3BM%C3%B6ller%2C+Kristian.&rft.aulast=Rajala&rft.aufirst=Risto&rft.date=2012-10-01&rft.volume=46&rft.issue=10&rft.spage=1368&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Marketing&rft.issn=03090566&rft_id=info:doi/10.1108%2F03090561211248071","Open source software; Qualitative research; Studies; Business And Economics--Marketing And Purchasing; Open source; Open-source software; Competition; Business model; Intellectual property; Business models; Case study; 5240:Software & systems; Public domain; Freeware; Innovations; Open innovation; 9130:Experimental/theoretical; Competitive advantage; Closed innovation; Flexibility; Market orientation; Scholarly publishing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It shows revenue generation factor, cost efficiency factor and growth factor to have a positive influence on the OSS of Indian MFIs. Adjusted impairment loan loss allowance ratio, a portfolio risk factor and average loan size per borrower, a development factor, are seen to have a negative influence on OSS of Indian MFIs. The results thus infer five significant factors that Indian MFI managers must concentrate on to enhance the OSS of their organizations. The authors then discuss how mismanaging these five factors can deviate an MFI from its social goal of poverty alleviation. The crisis in Indian microfinance industry is explored to unveil the dangers involved in mismanagement of these factors. The paper concludes by stating that it is imperative for Indian MFI managers to introspect about their lending and recovery practices, so as to ensure that they manage the factors affecting their OSS, without exploiting the poor clientele.","2012","2025-04-25 16:59:51","2025-04-25 16:59:51","","448","","3","2","","","","","","","","","","English","","","ABI/INFORM Global","1417567674","","","Place: Karachi Publisher: Asian Economic and Social Society","","; ","https://media.proquest.com/media/hms/OBJ/nDvoU?_a=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%3D%3D&_s=hVAYAXGCnKFve08NUURz%2BdlefTk%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Asian+Economic+and+Financial+Review&rft.atitle=Dangers+in+Mismanaging+the+Factors+Affecting+the+Operational+Self-Sustainability+%28OSS%29+of+Indian+Microfinance+Institutions+%28MFIs%29+-+An+Exploration+into+Indian+Microfinance+Crisis&rft.au=Nadiya%2C+M%3BOlivares-Polanco%2C+Francisco%3BRamanan%2C+T+Radha.&rft.aulast=Nadiya&rft.aufirst=M&rft.date=2012-04-01&rft.volume=2&rft.issue=3&rft.spage=448&rft.isbn=&rft.btitle=&rft.title=Asian+Economic+and+Financial+Review&rft.issn=23052147&rft_id=info:doi/","India; Business And Economics; Trends; Sustainability; Costs; Literature reviews; Poverty; Graduate students; Growth factors; Interest rates; Loan; Mechanical engineering; Microfinance; Microfinance Crisis; Mismanagement; Multiple regression analysis; Social goals","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One way federal procurement regulations advance public interest is by seeking ""optimal"" or ""best"" value in purchasing decisions. For each purchasing option, one determines the net benefit, which is a discounted difference between all present and future costs and benefits. This study considers the implications of pricing thresholds on government procurement processes in light of the advent and increasing use of free enterprise software. Researchers conducted a randomized Web-based survey of 138 government procurement officials (IT managers). The results indicate that free software may provide procurement officials with an opportunity to bypass institutionalized procurement best practices. The fieldwork indicates that IT purchases made through a full procurement process may enjoy a higher level of satisfaction than purchases of paid and free software acquired with limited or no procurement process review.","2012","2025-04-25 16:59:51","2025-04-25 16:59:51","","197-226,230","","2","41","","","","","","","","","","English","","","ABI/INFORM Global","1017544868","","","Place: Chicago Publisher: American Bar Association","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Public+Contract+Law+Journal&rft.atitle=GOVERNMENT+IT+PROCUREMENT+PROCESSES+AND+FREE+SOFTWARE&rft.au=Iansiti%2C+Marco.&rft.aulast=Iansiti&rft.aufirst=Marco&rft.date=2012-01-01&rft.volume=41&rft.issue=2&rft.spage=197&rft.isbn=&rft.btitle=&rft.title=Public+Contract+Law+Journal&rft.issn=00333441&rft_id=info:doi/","Law; Decision making; Information technology; Studies; Software; Free software; Government; Costs; Business models; 9130:Experiment/theoretical treatment; Freeware; United States--US; 9190:United States; 9550:Public sector; 5120:Purchasing; 5220:Information technology management; Best practice; Budgets; Government procurement; Government purchasing; Neutrality; Procurement; Public interest; Purchase options; User satisfaction","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on information gathered from the open-source website (www.osor.eu) we have built a database of open-source public interventions, establishing that public support in Europe for open-source software is usually reflected in direct adoption by a public partner or in positive statements about such adoption. Our analysis suggests that a serious analysis of the rationality, motivations and consequences of such public interventions involves a careful examination of the various roles of the public powers and the various categories of software involved. We provide empirical evidence that FOSS support is stronger in countries (i) where e-government services are more largely available, and (ii) where the domestic software industry is lagging behind. This evidence supports common views among FOSS advocates.","2011","2025-04-25 16:59:52","2025-04-25 16:59:52","","89-108","","136","","","","","","","","","","","English","","","ABI/INFORM Global","1586117312","","","Place: Brussels Publisher: Editions De Boeck Superieur","","; ","https://media.proquest.com/media/hms/OBJ/sGIGV?_a=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%3D%3D&_s=k%2B39lyKXr8S7K4tL52QHDuOJqjQ%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Revue+d%27%C3%89conomie+Industrielle&rft.atitle=PUBLIC+INTERVENTION+FOR+FREE%2FOPEN+SOURCE+SOFTWARE&rft.au=Comino%2C+Stefano%3BManenti%2C+Fabio+M%3BRossi%2C+Alessandro.&rft.aulast=Comino&rft.aufirst=Stefano&rft.date=2011-10-01&rft.volume=&rft.issue=136&rft.spage=89&rft.isbn=&rft.btitle=&rft.title=Revue+d%27%C3%89conomie+Industrielle&rft.issn=01543229&rft_id=info:doi/","Open source software; Information technology; Open source; Software; Public policy; Intellectual property; Electronic government; 5240:Software & systems; Impact analysis; Public domain; 51321:Software Publishers; Software industry; Innovations; Code reuse; E-government; Public sector; 9175:Western Europe; 1130:Economic theory; Free and open-source software; Cost control; Business And Economics--Production of Goods And Services; 92114:Executive and Legislative Offices, Combined; Public administration; France; Computer based modeling; Intervention","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We argue to the contrary that contemporary business and economic trends definitively demonstrate the financial viability of an economy based on free software. But the argument for free software derives its true normative weight from social justice considerations: the evaluation of the basis for a software economy should be guided by consideration of the social and cultural states which are the ultimate goals of any economic arrangement. That is, the software economy should be evaluated in light of its ability to provide justice.

However, these have had less influence in China thus far, though there has been a rapid growth of free/open source software in China. This article argues that China now needs a different voice against the IPR dogma and should make a contribution to the international effort against intellectual monopoly, and the software industry could be where to start. On one hand, China should take further measures to promote the development of free/open source software. On the other hand, China needs to scrutinize and reform relevant economic and legal systems and adjust strategy for international negotiations, strengthening antitrust enforcement against software monopoly and taking a tough stance against software patents in international community.

Felin and N. J. Foss, 'The Endogenous Origins of Experience, Routines and Organizational Capabilities: The Poverty of Stimulus', published by the Journal of Institutional Economics. Although valuable points are raised, the assessment is largely off target because it is fixated on the implausible view that the literature assessed is strongly shaped by the tradition of behavioral psychology (B. F. Skinner and others). At the same time, important portions of the routines and capabilities literature that are highly relevant to the authors' substantive concerns, and which are plainly inconsistent with the main interpretive claim, are not considered.

Felin and N. J. Foss, 'The Endogenous Origins of Experience, Routines and Organizational Capabilities: The Poverty of Stimulus', published by the Journal of Institutional Economics. The emphasis here is on practice-based theories of organizational routines that are grounded in close, ethnographic observation of real routines. While this literature may be unfamiliar to some readers, it is relevant here because it specifically contradicts the core assertions made by Felin and Foss. Further, this literature provides a clear theoretical foundation for subsequent research on problems such as stability and change in routines, the nature of capabilities and dynamic capabilities, and complex ecologies of routines.

We present occupancy and patient scheduling models to help address these challenges. These patient flow models can be used to explore the relationship between procedure scheduling practices and the resulting occupancy on inpatient obstetrical units such as labor and delivery and postpartum. The models capture numerous important characteristics of inpatient obstetrical patient flow such as time of day and day of week dependent arrivals and length of stay, multiple patient types and clinical interventions, and multiple patient care units with inter-unit patient transfers. We have used these models in several projects at different hospitals involving design of procedure scheduling templates and analysis of inpatient obstetrical capacity. In the development of these models, we made heavy use of open source software tools and have released the entire project as a free and open source model and software toolkit.[PUBLICATION ABSTRACT]","2011-03","2025-04-25 16:59:53","2025-04-25 16:59:53","","56-73","","1","14","","","","","","","","","","English","","","ABI/INFORM Global","848542518; 20978855","","","Place: New york Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/uZM9U?_a=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%3D%3D&_s=JDm8z6cfbbW3FS8G2S9pPjburKU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Health+Care+Management+Science&rft.atitle=An+open+source+software+project+for+obstetrical+procedure+scheduling+and+occupancy+analysis&rft.au=Isken%2C+Mark+W%3BWard%2C+Timothy+J%3BLittig%2C+Steven+J.&rft.aulast=Isken&rft.aufirst=Mark&rft.date=2011-03-01&rft.volume=14&rft.issue=1&rft.spage=56&rft.isbn=&rft.btitle=&rft.title=Health+Care+Management+Science&rft.issn=13869620&rft_id=info:doi/10.1007%2Fs10729-010-9141-8","Open source software; Female; Studies; Software engineering; Open-source software; Patients; Humans; Hospitals; 5240:Software & systems; Public domain; 9130:Experimental/theoretical; 9175:Western Europe; International; 62211:General Medical and Surgical Hospitals; 8320:Health care industry; Appointments & Schedules; Births; Cesarean section; Cesarean Section -- statistics & numerical data; Efficiency, Organizational; Health care industry; Health Facilities And Administration; Induced labor; Labor, Induced -- statistics & numerical data; Length of stay; Obstetrics; Obstetrics & Gynecology Department, Hospital -- organization & administration; Postpartum period; Pregnancy; Process Assessment (Health Care) -- statistics & numerical data; Scheduling; Software Design; Time Factors; Vagina; Workforce planning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Adoption studies represent a particularly promising area for information system researchers to investigate the relationship between the specific properties of FLOSS and the processes of implementation and use.

As the most interesting results, our multivariate analyses of developers' code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early-as the ""credible promise"" in OSS-leads to increased reuse. Finally, we identify developers' interest in tackling difficult technical challenges as detrimental to efficient reuse-based innovation. Beyond OSS, we discuss the relevance of our findings for companies developing software and for the receiving side of open innovation processes, in general.

Examining what motivates participants in OSS projects and how to enhance the effects of motivations has received increased attention in recent years. This study is prompted by the significant but detail-lacking examination of differential effects of various types of extrinsic motivations on participants' task effort in OSS projects and their interaction effects with participants' psychological states. Drawing upon self-determination theory, we establish four types of extrinsic motivations in OSS communities (i.e., external, introjected, identified, and integrated motivation) and investigate how these types affect task effort differently. Also, integrating self-determination theory with affective event theory, we study how satisfaction of needs for competence, autonomy, and relatedness moderates the relationships between extrinsic motivations and task effort. The research model is largely supported by data from 250 participants in various OSS projects. Theoretical contribution and practical implications are discussed.

Project communities and customer pipelines are not the same thing, although some participants belong to both groups. This creates confusion in the business and tension with the community. F/LOSS communities have been on the rise for the past two decades. Companies began to form around F/LOSS projects in the early 1990s, with some creating their own F/LOSS projects and some wrapping themselves around existing projects. This has created tension between company managers who are trying to earn profits from software that is ""available for free,"" and from developers in communities that do not necessarily want to create software for someone else's corporate gain. This happens regardless of whether the company created the F/LOSS-licensed project itself, or participates in external communities around other projects, or both. This article demonstrates that separating the concepts of community and customer, and of project and product, allows a business to manage clearly both challenges of developing an engaged community and maximizing profits.","2010-10","2025-04-25 16:59:53","2025-04-25 16:59:53","","5-13","","","","","","","","","","","","","English","","","ABI/INFORM Global","1695042597","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/gCfiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk1MDQyNTk3Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMTAvMTAvMDFyCjIwMTAvMTAvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=iIQy0fuCTuZFWuw6MqauZu0jZFs%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=Differentiating+Community+from+Customers+in+an+F%2FLOSS+Business&rft.au=Aslett%2C+Matthew%3BWalli%2C+Stephen.&rft.aulast=Aslett&rft.aufirst=Matthew&rft.date=2010-10-01&rft.volume=&rft.issue=&rft.spage=&rft.isbn=&rft.btitle=&rft.title=&rft.issn=&rft_id=info:doi/","Open source software; Community; Canada; Business And Economics; Collaboration; Marketing; Customers; Business; Internet; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Project; Research & development--R&D; Loss; 9172:Canada; Customer relationship management; 2400:Public relations; Customer; Product; Profit maximization","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

Yet, in 1992, everyone agreed there was still much work to be done. Even today, you still strive for a desktop and server operating system, with all relevant applications, that grants complete software freedom. Hardware companies are not the only entity interested in phone operating systems. Google, ever-focused on routing human eyes to its controlled advertising, realizes that even more eyes will be on mobile computing platforms in the future. With this goal in mind, Google released the Android/Linux system, now available on a variety of phones in varying degrees of software freedom. Seeking software freedom on mobile devices will remain a complicated endeavour for some time.

The participants feel that they belong to the community and many also feel that they are recognised as part of the community.

Guest Editors: Wei Jiang and Anurag Agarwal and Regular papers This paper develops tests and validates a model for the antecedents of open source software (OSS) defects, using Data and Text Mining. The public archives of OSS projects are used to access historical data on over 5,000 active and mature OSS projects. Using domain knowledge and exploratory analysis, a wide range of variables is identified from the process, product, resource, and end-user characteristics of a project to ensure that the model is robust and considers all aspects of the system. Multiple Data Mining techniques are used to refine the model and data is enriched by the use of Text Mining for knowledge discovery from qualitative information. The study demonstrates the suitability of Data Mining and Text Mining for model building. Results indicate that project type, end-user activity, process quality, team size and project popularity have a significant impact on the defect density of operational OSS projects. Since many organizations, both for profit and not for profit, are beginning to use Open Source Software as an economic alternative to commercial software, these results can be used in the process of deciding what software can be reasonably maintained by an organization.

The purpose of this paper is to describe the software architecture. Design/methodology/approach - The DEM chosen uses position, orientation, velocity and angular velocity as independent variables of simulated particles which are subject to explicit leapfrog time-integration scheme (Lagrangian method). The three-dimensional dynamics equations based on the classical Newtonian approach for the second law of motion are used. The track of forces and moments acting on each particle is kept at every time step. Contact forces depend on the particle geometry overlap and material properties. The normal, tangential and moment components of interaction force are included. Findings - An effort is undertaken to extract the underlying object oriented abstractions in the DEM. These abstractions are implemented in C++, conform to object oriented design principles and use design patterns. Based on that, a software framework is developed in which the abstractions provide the interface where the modelling methods can be plugged-in. Originality/value - The resulting YADE-OPEN DEM framework is designed in a generic way which provides great flexibility when adding new scientific simulation code. Some of the advantages are that numerous simulation methods can be coupled within the same framework while plug-ins can import data from other software. In addition, this promotes code improvement through open-source development and allows feedback from the community. However implementing such models requires that one adheres to the framework design and the YADE framework is a new emerging software. To download the software see http : //yade.wikia.com webpage.

OSS/FS alternatives complicate an already complex information goods market plagued by piracy concerns. Although producer perspectives on software pricing and piracy controls have been addressed extensively, consumers' perspective and willingness to pay for commercial software is not very well understood. This paper empirically determines willingness to pay for a leading commercial software application (Microsoft Office) in the presence of an OSS/FS alternative. A contingent valuation approach is used to elicit willingness to pay for the application. The research design employs a 2 × 2 × 2 experiment to investigate the impact of preventive control, deterrence control, and OSS/FS alternative. The results indicate that the availability of an OSS/FS alternative has little impact on willingness to pay for Microsoft Office. However, piracy controls significantly increase willingness to pay for Microsoft Office, even in the presence of OSS/FS alternatives.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.

A number of highly influential papers have argued that the self-fulfilling nature of (even false) theories provides the underlying mechanism through which economics has adversely shaped not just social science but also management practice and individual behavior. We question these arguments and argue that there are important boundary conditions to theories falsely fulfilling themselves, boundary conditions that have hitherto been unexplored in organizational research, and boundary conditions that question the underlying premises used by organizational scholars and social scientists to attack economics. We specifically build on highly relevant findings from social psychology, philosophy, and organizational economics to show how (1) objective reality and (2) human nature provide two important boundary conditions for theories (falsely or otherwise) fulfilling themselves. We also defend organizational economics, specifically the use of high-powered incentives in organizations, and argue that self-interest (rightly understood) facilitates in creating beneficial individual and collective and societal outcomes.

Their initial experiences applying the tool in an R&D organization indicate that it helps establish a systematic project monitoring and control process by supporting or automating tasks. In this way, it presents an open, flexible, and free tool-integration solution for project management, illustrating that open-source tools might be appealing, especially for small organizations.

This is in spite of: 1. the rise in commercial development and support for F/LOSS, 2. the goal of most F/LOSS projects to incorporate improvements, which is actually a form of financial gain, 3. official definitions of ""commercial item"" that include F/LOSS, and 4. F/LOSS licenses and projects that clearly approve of commercial support. In reality there are two types of commercial software: proprietary software and F/LOSS. This paper provides examples for each of the four points mentioned, briefly notes some alternative terms, and ends with some conclusions, explaining why it is important to understand that F/LOSS software is almost always commercial.","2009-02","2025-04-25 16:59:54","2025-04-25 16:59:54","","25-33","","","","","","","","","","","","","English","","","ABI/INFORM Global","1695041145","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/SyeiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk1MDQxMTQ1Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDkvMDIvMDFyCjIwMDkvMDIvMjh6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Z%2FONeSv%2BFIZIROjIrDVn3%2F5s6x0%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=F%2FLOSS+IS+COMMERCIAL+SOFTWARE&rft.au=Wheeler%2C+David+A.&rft.aulast=Wheeler&rft.aufirst=David&rft.date=2009-02-01&rft.volume=&rft.issue=&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Business And Economics; Open source; Software; Licenses; Linux; Business models; 5240:Software & systems; Public domain; United States--US; 9190:United States; 2310:Planning; Loss; Government purchasing; Nonprofit organizations; Commercialization; Royalties; Commercial; Commercial software; Investments; Proprietary software","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-04-25 16:59:55","2025-04-25 16:59:55","","449-462","","5","16","","","","","","","","","","English","","","ABI/INFORM Global","212365312","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/b6OaT?_a=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%3D%3D&_s=SoMHSxzncc%2FFgWIjigCYfocNCzU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Management+%26+Computer+Security&rft.atitle=Evaluating+the+performance+of+open+source+software+projects+using+data+envelopment+analysis&rft.au=Wray%2C+Barry%3BMathieu%2C+Richard.&rft.aulast=Wray&rft.aufirst=Barry&rft.date=2008-10-20&rft.volume=16&rft.issue=5&rft.spage=449&rft.isbn=&rft.btitle=&rft.title=Information+Management+%26+Computer+Security&rft.issn=09685227&rft_id=info:doi/10.1108%2F09685220810920530","Open source software; Studies; Productivity; Business And Economics--Management; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, when one plans to study the adequacy of open source software (OSS), it is necessary to have a method of qualification and selection adapted to the characteristics of this type of software and to precisely examine the constraints and risks specific to OSS. Since the open source field has a very broad scope, it is also necessary to use a qualification method that differentiates between numerous candidates to meet technical, functional and strategic requirements. The vast amount of available OSS software requires a methodology to allow for the evaluation of potential candidates to meet business requirements. The QSOS methodology allows for an iterative needs analysis for gauging the technical, functional, and strategic capabilities of OSS products.","2008-05","2025-04-25 16:59:55","2025-04-25 16:59:55","","10-16","","","","","","","","","","","","","English","","","ABI/INFORM Global","1694724606","","","Place: Ottawa Publisher: Talent First Network","","; ","https://media.proquest.com/media/hms/ORIG/1/NteiC?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgcyMDM2MTk4MgoxNjk0NzI0NjA2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDgvMDUvMDFyCjIwMDgvMDUvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Nzc1rGWsZxtiJvHZ4KTJ%2FI3GuNU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Open+Source+Business+Resource&rft.atitle=QUALIFICATION+%26amp%3B+SELECTION+OF+OSS&rft.au=Semeteys%2C+Rapha%C3%ABl.&rft.aulast=Semeteys&rft.aufirst=Rapha%C3%ABl&rft.date=2008-05-01&rft.volume=&rft.issue=&rft.spage=10&rft.isbn=&rft.btitle=&rft.title=The+Open+Source+Business+Resource&rft.issn=&rft_id=info:doi/","Open source software; Information systems; Business And Economics; Open-source software; Licenses; Risk; Strategy; Qualifications; ISO standards; 5240:Software & systems; United States--US; 9190:United States; Component-based software engineering; Need; Qualification; Selection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Employees belonging to the open source movement often advocate the use of open source software within their organization. Hence, their belief in the underlying open source software ideology may influence the decision making on the adoption of open source software. This may result in an ideological—rather than pragmatic—decision. A recent study has shown that American organizations are quite pragmatic in their adoption decision. We argue that there may be circumstances in which there is more opportunity for ideological behavior. We therefore investigated the organizational adoption decision in Belgian organizations. Our results indicate that most organizations are pragmatic in their decision making. However, we have found evidence that suggests that the influence of ideology should not be completely disregarded in small organizations.","2008","2025-04-25 16:59:55","2025-04-25 16:59:55","","58-72","","2","19","","","","","","","","","","English","","","ABI/INFORM Global","2954642502","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/XD6YX?_a=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%3D%3D&_s=ww6xE5v2UXxv23OVeBXco526Ds4%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=The+Impact+of+Ideology+on+the+Organizational+Adoption+of+Open+Source+Software&rft.au=Ven%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Ven&rft.aufirst=Kris&rft.date=2008-01-01&rft.volume=19&rft.issue=2&rft.spage=58&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2008040103","Open source software; Organizations; Decision making; Open source; Software; Open-source software; Adoption; Computers--Data Base Management; Ideology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We begin by measuring the digital divide in these very different regions of the world. Our research demonstrates, both quantitatively and qualitatively, how the digital divide places populations in both regions at a disadvantage. Next we examine the role of these technologies in bridging the digital divide along three complementary dimensions. First, we show that both affordable technology and sound policy are necessary for digital inclusion. Second, we look at how these two technologies are extended, integrated, and customized in information and communication technology (ICT) solutions that are both creative and effective.

Qualitative data were collected over a four year period using a virtual ethnography in a study of free and open source software development and, in particular, a study of a free software community, GNUenterprise, located at www.gnuenterprise.org, which has the goal of developing a free enterprise resource planning software system. It is concluded that the ideology of the free software movement continues to be one of the factors which mobilize people to contribute to free and open source software development. This movement represents a new type of computerization movement which promotes the investment of time in learning a new software development process instead of investment of money in the acquisition and use of new technology. The research findings are limited by a detailed study of only one free software development project. This paper is of significance to software developers and managers of firms who wish to incorporate free and open source software into their companies. This research presents an original conceptual diagram and framework for how computerization movements have emerged into an occupational community.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain.","2008","2025-04-25 16:59:55","2025-04-25 16:59:55","","142-156","","1","11","","","","","","","","","","English","","","ABI/INFORM Global","211770348","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/aQ4UT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNjE2NDIJMjExNzcwMzQ4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDgvMDEvMDFyCjIwMDgvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=SAswoqID8hrBd8RAEe40nEM7N%2FU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=European+Journal+of+Innovation+Management&rft.atitle=Online+innovation%3A+the+case+of+open+source+software+development&rft.au=Vujovic%2C+Sladjana%3BUlh%C3%B8i%2C+John+Parm.&rft.aulast=Vujovic&rft.aufirst=Sladjana&rft.date=2008-01-01&rft.volume=11&rft.issue=1&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=European+Journal+of+Innovation+Management&rft.issn=14601060&rft_id=info:doi/10.1108%2F14601060810845268","Open source software; Innovation; Communication; Information technology; Studies; Business And Economics--Management; Collaboration; Marketing; Open source; Product development; Coordination; Knowledge; Resource management; Cooperation; Internet; Social networks; Software development; Business models; Computer industry; Public domain; Technological change; Innovations; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; 1220:Social trends & culture; 5250:Telecommunications systems & Internet communications; 33411:Computer and Peripheral Equipment Manufacturing; 8651:Computer industry; Manufacturers; Metaphor","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This shift is not only redefining the software industry but also the way we teach and learn in our software engineering (SE) courses. But for many universities F/OSS is seen as an optional low cost technology to support the IT infrastructure and administrational duties. Few see F/OSS as an opportunity for students to learn the SE concepts and skills we teach. Furthermore, it is still an open question as to whether the F/OSS methodology can be effectively used to teach SE courses within the formally structured curriculum in most universities. This paper discusses F/OSS projects as bazaars of learning that offer a meaningful learning context. The discussion is centered on a pilot study in which students were involved in software testing in F/OSS projects. We present the teaching and learning framework we used in the pilot study and report on our experiences, lessons learned, and some practical problems we encountered. Our grading and evaluation approach show that the students did relatively well as bug hunters and reporters. Results from two online surveys indicate that students are motivated in participating in software testing in the bazaar, and they are willing to participate in project activities long after their graduation. The study reveals one possible way SE educators can teach and integrate F/OSS into their formal curricular structure.

On the negative side, this increasing dependence on computers has resulted in research that has become increasingly difficult to replicate. In this paper, we propose some basic standards to improve the production and reporting of computational results in economics for the purpose of accuracy and reproducibility. In particular, we make recommendations on four aspects of the process: computational practice, published reporting, supporting documentation, and visualization. Also, we reflect on current developments in the practice of computing and visualization, such as integrated dynamic electronic documents, distributed computing systems, open source software, and their potential usefulness in making computational and empirical research in economics more easily reproducible.

This article evidences the hypothesis that it is possible to adopt the knowledge management with the union and customization of the free software tools. In such a way, any organization can act in the technological management and apply the politics of knowledge management, either to a micro-company or a great corporation. A case study is presented in a technological undergraduate course of a Federal Center of Technological Education. The study case presents the research and the development of an innovative model of management for the course. Finally, the authors defend that this model can be applied to other organizations based upon a series of results and conclusions.

Three projects were selected from SourceForge.net in terms of their similarities as well as their differences. Monthly data were extracted from the bug tracking systems in order to achieve a longitudinal view of the interaction pattern of each project. Social network analysis was used to generate the indices of social structure. The finding suggests that the interaction pattern of OSS projects evolves from a single hub at the beginning to a core/periphery model as the projects move forward.","2007","2025-04-25 16:59:56","2025-04-25 16:59:56","","25-40","","2","18","","","","","","","","","","English","","","ABI/INFORM Global","2954642984","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/vD6YX?_a=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%3D%3D&_s=YpJkHh7RL5XJbFdZMoXj0WZubjg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Database+Management&rft.atitle=Social+Network+Structures+in+Open+Source+Software+Development+Teams&rft.au=Long%2C+Yuan%3BSiau%2C+Keng.&rft.aulast=Long&rft.aufirst=Yuan&rft.date=2007-01-01&rft.volume=18&rft.issue=2&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=Journal+of+Database+Management&rft.issn=10638016&rft_id=info:doi/10.4018%2Fjdm.2007040102","Open source software; Social network analysis; Open source; Open-source software; Network analysis; Teams; Social networks; Software development; Computers--Data Base Management; Social network; Tracking systems","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We argue for the importance of studying open source software use and propose a framework to guide research in this area. The framework describes four main areas of investigation: the creation of OSS user communities, their characteristics, their contributions and how they change. For each area of the framework, we suggest several research questions that deserve attention.","2007","2025-04-25 16:59:56","2025-04-25 16:59:56","","68-80","","1","20","","","","","","","","","","English","","","ABI/INFORM Global","2931884467","","","Place: Hershey Publisher: IGI Global","","; ","https://media.proquest.com/media/hms/PFT/1/bEmQX?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=klft04rXJ8JdsnSiMgYFKEvM39o%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Resources+Management+Journal&rft.atitle=Beyond+Development%3A+A+Research+Agenda+for+Investigating+Open+Source+Software+User+Communities&rft.au=Jin%2C+Leigh%3BRobey%2C+Daniel%3BBoudreau%2C+Marie-Claude.&rft.aulast=Jin&rft.aufirst=Leigh&rft.date=2007-01-01&rft.volume=20&rft.issue=1&rft.spage=68&rft.isbn=&rft.btitle=&rft.title=Information+Resources+Management+Journal&rft.issn=10401628&rft_id=info:doi/10.4018%2Firmj.2007010105","Open source software; Information systems; Business And Economics--Management; Open source; Open-source software; Software development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, a realistic assessment of OSS projects, specifically the motivations of OSS developers and their attitude toward software usability, lack of user feedback, and absence of usability experts in OSS projects, leads to the conclusion that strategies to improve OSS usability are unlikely to succeed anytime soon. The only exceptions will be OSS which enjoy sufficient financial support from individuals and organizations, and software that were developed by commercial software producers and later released under an open source license.","2007","2025-04-25 16:59:56","2025-04-25 16:59:56","","25","","","20","","","","","","","","","","English","","","ABI/INFORM Global","2500547773","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/jgCVI?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNjQyNTIKMjUwMDU0Nzc3MzoNRG9jdW1lbnRJbWFnZUIBMFIGT25saW5lWgJGVGIDUEZUagoyMDA3LzAxLzAxcgoyMDA3LzEyLzMxegCCASVQLTEwMDAwMDEtMTI4NjEtQ1VTVE9NRVItbnVsbC0xMTQ0NDAykgEGT25saW5lygFUTW96aWxsYS81LjAgKE1hY2ludG9zaDsgSW50ZWwgTWFjIE9TIFggMTAuMTU7IHJ2OjEzNS4wKSBHZWNrby8yMDEwMDEwMSBGaXJlZm94LzEzNS4w0gESU2Nob2xhcmx5IEpvdXJuYWxzmgIHUHJlUGFpZKoCK09TOkVNUy1NZWRpYUxpbmtzU2VydmljZS1nZXRNZWRpYVVybEZvckl0ZW3KAg9BcnRpY2xlfEZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Le83Zx8YqbLXdrH3QZy1qQV5GyE%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Waiting+for+Usable+Open+Source+Software%3F+Don%27t+Hold+Your+Breath%21&rft.au=Sen%2C+Ravi.&rft.aulast=Sen&rft.aufirst=Ravi&rft.date=2007-01-01&rft.volume=20&rft.issue=&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.02025","Open source software; Open source; Software engineering; Software; Open-source software; Usability; Computers--Information Science And Information Theory; Software development; Software quality; Public domain","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper develops and tests a model of the impacts of license restrictiveness and organizational sponsorship on two indicators of success: user interest in, and development activity on, open source software development projects. Using data gathered from Freshmeat.net and project home pages, the main conclusions derived from the analysis are that (1) license restrictiveness and organizational sponsorship interact to influence user perceptions of the likely utility of open source software in such a way that users are most attracted to projects that are sponsored by nonmarket organizations and that employ nonrestrictive licenses, and (2) licensing and sponsorship address complementary developer motivations such that the influence of licensing on development activity depends on what kind of organizational sponsor a project has. Theoretical and practical implications are discussed, and the paper outlines several avenues for future research.

Service discovery is an essential mechanism to achieve this goal. Driven primarily by the OSS requirements, this paper proposes a new service discovery methodology for next generation OSS -- model-based service discovery (MBSD). MBSD takes advantage of the OMG MDA (model-driven architecture) technology. The system architecture of MBSD and its operation and implementation are presented. The proposed methodology is briefly validated through an OSS scenario.

However, he defines knowledge in terms that make it amenable to a certain form of economic analysis, and thus overlooks potential insights from other perspectives. As soon as sociological issues are taken into account, the concept of knowledge has to be broadened, and also his theory of control. In particular, the role of the community or group in knowledge creation has to be allowed for. Although sociological and economics-based explanations are sometimes presented as conflicting alternatives, there is no inevitable reason why sociological and economics-based perspectives cannot be integrated in a common framework.","2006","2025-04-25 16:59:57","2025-04-25 16:59:57","","21-27","","1","10","","","","","","","","","","English","","","ABI/INFORM Global","200688856","","","Place: Dordrecht Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/MHKxS?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUyNTk1NzIJMjAwNjg4ODU2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=5cofK6cscbNkfIthyEbHHjAiWyU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+%26+Governance&rft.atitle=Knowledge+in+the+Theory+of+the+Firm+and+MNC%3A+Asset+or+Action%3F+A+Commentary+on+Foss+N.+%26quot%3BKnowledge+and+Organisation+in+the+Theory+of+the+MNC%26quot%3B&rft.au=Barnard%2C+Helena%3BCantwell%2C+John.&rft.aulast=Barnard&rft.aufirst=Helena&rft.date=2006-03-01&rft.volume=10&rft.issue=1&rft.spage=21&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+%26+Governance&rft.issn=13853457&rft_id=info:doi/10.1007%2Fs10997-005-3546-7","Sociology; Studies; Knowledge; Knowledge management; Knowledge economy; Economics; Control theory; 2500:Organizational behavior; 9130:Experimental/theoretical; 1130:Economic theory; Business And Economics--Banking And Finance; Economic theory; Multinational corporations; 1220:Social trends & culture; Communities of practice; Theory of the firm","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some governments have actually begun to procure FLOSS, whereas others have channeled public funds to large-scale FLOSS projects. This study demonstrates both the benefits and the risks of government policy favoring FLOSS from the perspective of economics, technology, and politics, and to further analyze whether these same policy goals can be achieved through government support of FLOSS. The most fundamental argument of the study is that, in lending its support to FLOSS, the difference between a government user and a business user is that the government should take into account society's long-term interests, not merely its own interests as a consumer.[PUBLICATION ABSTRACT]","2006","2025-04-25 16:59:57","2025-04-25 16:59:57","","113-141","","4","18","","","","","","","","","","English","","","ABI/INFORM Global","821676609","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/bX87U?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU3NTkzNzIJODIxNjc2NjA5Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=YM1BXdESXYlFxwNLnjdbPXVMORU%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Government+policy+toward+open+source+software%3A+The+puzzles+of+neutrality+and+competition&rft.au=Lee%2C+Jyh-an.&rft.aulast=Lee&rft.aufirst=Jyh-an&rft.date=2006-01-01&rft.volume=18&rft.issue=4&rft.spage=113&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-006-1007-5","Open source software; Sociology; Open source; Open-source software; Public policy; Open data; Open innovation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We begin by answering perhaps the most basic question: what is the social structure of these teams? We conducted social network analyses of bug-fixing interactions from three repositories: Sourceforge, GNU Savannah and Apache Bugzilla. We find that some OSS teams are highly centralized, but contrary to expectation, others are not. Projects are mostly quite hierarchical on four measures of hierarchy, consistent with past research but contrary to the naive image of these projects. Furthermore, we find that the level of centralization is negatively correlated with project size, suggesting that larger projects become more modular, or possibly that becoming more modular is a key to growth. The paper makes a further methodological contribution by identifying appropriate analysis approaches for interaction data. We conclude by sketching directions for future research.[PUBLICATION ABSTRACT]","2006","2025-04-25 16:59:57","2025-04-25 16:59:57","","65-85","","4","18","","","","","","","","","","English","","","ABI/INFORM Global","821676606","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/wU87U?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU3NTkzNzIJODIxNjc2NjA2Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMDMvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=cZbfxGayBRxpOd3OqV05XabWcnA%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Hierarchy+and+centralization+in+free+and+open+source+software+team+communications&rft.au=Crowston%2C+Kevin%3BHowison%2C+James.&rft.aulast=Crowston&rft.aufirst=Kevin&rft.date=2006-01-01&rft.volume=18&rft.issue=4&rft.spage=65&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-006-1004-8","Open source software; Remote work; Sociology; Social network analysis; Open source; Software; Open-source software; Hierarchy; Public domain; Centralisation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The paper briefly traces the economic significance of the software industry and the dominance in packaged software of the large US publishers, the phenomena of natural monopolies building in software packages, and the need for different industry structure for Europe, as it exhibits a small to medium-sized enterprise (SME) and system integrator structure. It then examines the balancing affects of OSS. The paper also addresses the role that poor software plays in creating new costs or externalities for its users when it fails, contrasting the robustness of open source in defect repair. The paper finds that the way forward in economic terms for Europe may well be to follow and encourage OSS for reasons of creating a strong software industry and for a counterbalance to current monopolistic trends. The paper's findings emphasise the need for investment, education and encouragement in OSS, by both the public and private sectors, to build a strong knowledge-based society in Europe. The paper introduces the ideas of the basic economic mechanisms of volume sales of software as a good, with analysis of the industry impacts of confluence of the network effect coupled with the law of increasing returns with volume to drive monopolistic positions in the proprietary software package industry.","2006","2025-04-25 16:59:57","2025-04-25 16:59:57","","12-31","","3","8","","","","","","","","","","English","","","ABI/INFORM Global","275029739","","","Place: Bradford Publisher: Emerald Group Publishing Limited","","; ","https://media.proquest.com/media/hms/OBJ/NWdDT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU0MjU0MTIJMjc1MDI5NzM5Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDYvMDEvMDFyCjIwMDYvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=raMMlF7qwlgTC1gQ%2B98jvK4%2BZWw%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Info+%3A+the+Journal+of+Policy%2C+Regulation+and+Strategy+for+Telecommunications%2C+Information+and+Media&rft.atitle=The+rain+forest+and+the+rock+garden%3A+the+economic+impacts+of+open+source+software&rft.au=Forge%2C+Simon.&rft.aulast=Forge&rft.aufirst=Simon&rft.date=2006-01-01&rft.volume=8&rft.issue=3&rft.spage=12&rft.isbn=&rft.btitle=&rft.title=Info+%3A+the+Journal+of+Policy%2C+Regulation+and+Strategy+for+Telecommunications%2C+Information+and+Media&rft.issn=14636697&rft_id=info:doi/10.1108%2F14636690610664633","Open source software; Productivity; Open source; Open-source software; Software packages; Communications; Economics; 5240:Software & systems; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Economic; Software industry; 9175:Western Europe; Network effect; United Kingdom--UK; Employees; Employment; Economic development; 1110:Economic conditions & forecasts; Consumer goods; Economic growth; Economic impact; Global economy; Gross Domestic Product--GDP; Rainforest; Rainforests; Sales; Tax revenues","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Aimed at enterprise-scale customers, these services range from the provision of IP-VPNs to full IT outsourcing, and span the range of infrastructure domains from desktop to data centre. The primary challenge lies not in the ICT infrastructure itself, but in the increasing demands placed upon the operational support systems (OSS) to deliver services holistically across the range of ICT operations. Based on BT's experience with corporate and government customers, this paper presents a detailed study of the ICT challenges on the OSS in achieving an end-to-end view of ICT service management. It proposes an architectural route forward and highlights BT's work on policy-based service management solutions.

Mass-market consumers can be divided between those who are informed about the existence of OSS and those who are uninformed. Since OSS producers have little incentive to advertise, there may be a substantial mass of uniformed consumers, leading to market failures that may justify government intervention. We study three government policies: (a) mandated adoption, whereby the government forces public agencies, schools, and universities to adopt OSS, (b) information provision, whereby the government informs the uninformed users about the existence and the characteristics of OSS, and (c) subsidy, whereby the government makes a payment to consumers if they adopt OSS. We show that mandated adoption and information provision may increase social welfare, but the subsidy always reduces it. When network externalities are added to the model, we show that mandated adoption and information provision may increase social welfare if they help the market to tip towards standardization.

It is an opportunity to diverge. We would therefore expect incompatible strains of software to develop, and consequently a demand for standardization to arise. However, this is only partly the case. In this paper we explore which other coordinative mechanisms are at work apart from committee standardization. We identify four other categories of coordinative mechanisms, and illustrate their relevance in OSS development. They complement committee standardization, can be used in standardization, and are sometimes an alternative to standardization.

Although resistance manifests itself in numerous ways, resistance to change is frequent when individuals are introduced to new ideas or innovations. This form of resistance can limit forward progress of either an individual or an organization. However, a few papers investigated possible positive roles of resistance in human life. This paper proposes that resistance can be a positive motivator to achieve change. Open source software (OSS) is a technological innovation that is laden with aspects of resistance. One of the initial motivations for the development of open source software was ""psychological reactance"" on the part of a few software developers. Reactance is a limited part of the overall construct of resistance; specifically, resistance caused by external threats to an individual's freedom of choice, which generally manifests itself affectively. This paper looks at the role of resistance as a motivator for technological innovation from the perspective of open source softwre development. It also presents techniques for overcoming resistance to the adoption of open source software. Specific techniques presented are the Alpha and Omega strategies for overcoming resistance. Alpha strategies work by attempting to increase the approach forces towards some goal. Conversely, Omega strategies attempt to decrease the avoidance forces, thereby removing resistance to change. Both techniques are used in the context of open source software development to motivate participants.","2004","2025-04-25 16:59:58","2025-04-25 16:59:58","","36","","","13","","","","","","","","","","English","","","ABI/INFORM Global","2500557958","","","Place: Atlanta Publisher: Association for Information Systems","","; ","https://media.proquest.com/media/hms/PFT/1/0oCVI?_a=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%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Jqqm1SdxriyuNZlg3X%2Bd0e11DNg%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Communications+of+the+Association+for+Information+Systems&rft.atitle=Resistance+as+Motivation+for+Innovation%3A+Open+Source+Software&rft.au=Kavanagh%2C+Joseph+F.&rft.aulast=Kavanagh&rft.aufirst=Joseph&rft.date=2004-01-01&rft.volume=13&rft.issue=&rft.spage=36&rft.isbn=&rft.btitle=&rft.title=Communications+of+the+Association+for+Information+Systems&rft.issn=&rft_id=info:doi/10.17705%2F1CAIS.01336","Open source software; Innovation; Motivation; Resistance; Open source; Open-source software; Computers--Information Science And Information Theory; Software development; Public domain; Innovations; Programmer; Reactance","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The ""private investment"" model assumes returns to the innovator result from private goods and efficient regimes of intellectual property protection. The ""collective action"" model assumes that under conditions of market failure, innovators collaborate in order to produce a public good. The phenomenon of open source software development shows that users program to solve their own as well as shared technical problems, and freely reveal their innovations without appropriating private returns from selling the software. This paper proposes that open source software development is an exemplar of a compound ""private-collective"" model of innovation that contains elements of both the private investment and the collective action models and can offer society the ""best of both worlds"" under many conditions. A new set of research questions this model raises for scholars in organization science are described.","2003-04","2025-04-25 16:59:58","2025-04-25 16:59:58","","209-223","","2","14","","","","","","","","","","English","","","ABI/INFORM Global","213832398","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","; ","https://media.proquest.com/media/hms/OBJ/D51gT?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgUxMTkyMTIJMjEzODMyMzk4Og1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjIwMDMvMDMvMDFyCjIwMDMvMDQvMzB6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCD0FydGljbGV8RmVhdHVyZdICAVnyAgD6AgFOggMDV2ViigMcQ0lEOjIwMjUwMjI3MDIwNDA3NjEzOjY2OTczMg%3D%3D&_s=0ARffPta%2Bf78rtxaNgkgiJ3O5ac%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Organization+Science&rft.atitle=Open+source+software+and+the+%26quot%3Bprivate-collective%26quot%3B+innovation+model%3A+Issues+for+organization+science&rft.au=Eric+von+Hippel%3BGeorg+von+Krogh.&rft.aulast=Eric+von+Hippel&rft.aufirst=&rft.date=2003-03-01&rft.volume=14&rft.issue=2&rft.spage=209&rft.isbn=&rft.btitle=&rft.title=Organization+Science&rft.issn=10477039&rft_id=info:doi/","Open source software; Innovation; Studies; Collective action; Business And Economics--Management; Collaboration; Artificial intelligence; Open-source software; Licenses; Incentives; Models; Software development; 5240:Software & systems; Public domain; Freeware; Innovations; Research & development--R&D; United States--US; 9130:Experimental/theoretical; 5400:Research & development; 9190:United States; Defense contracts; Laboratories; Licensing; Organization science; Organization studies; Programmers; Research & development","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Metadata is examined from the Linux Software Map (LSM), which documents many open source projects, and Sourceforge, one of the largest resources for open source developers.

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992) This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-04-25 16:59:59","2025-04-25 16:59:59","","94-112","","3","12","","","","","","","","","","English","","","ABI/INFORM Global","821692253","","","Place: New York Publisher: Springer Nature B.V.","","; ","https://media.proquest.com/media/hms/OBJ/8v97U?_a=ChgyMDI1MDIyNzAyMDQwNzYxMjo5MDE0MTUSBTk5OTQxGgpPTkVfU0VBUkNIIg0xNjUuMTI0LjE2Ny4xKgU3NTkzNzIJODIxNjkyMjUzOg1Eb2N1bWVudEltYWdlQgEwUgZPbmxpbmVaAkZUYgNQRlRqCjE5OTkvMTAvMDFyCjE5OTkvMTIvMzF6AIIBJVAtMTAwMDAwMS0xMjg2MS1DVVNUT01FUi1udWxsLTExNDQ0MDKSAQZPbmxpbmXKAVRNb3ppbGxhLzUuMCAoTWFjaW50b3NoOyBJbnRlbCBNYWMgT1MgWCAxMC4xNTsgcnY6MTM1LjApIEdlY2tvLzIwMTAwMTAxIEZpcmVmb3gvMTM1LjDSARJTY2hvbGFybHkgSm91cm5hbHOaAgdQcmVQYWlkqgIrT1M6RU1TLU1lZGlhTGlua3NTZXJ2aWNlLWdldE1lZGlhVXJsRm9ySXRlbcoCB0ZlYXR1cmXSAgFZ8gIA%2BgIBToIDA1dlYooDHENJRDoyMDI1MDIyNzAyMDQwNzYxMzo2Njk3MzI%3D&_s=Qza5MQhKz7ImorWtd5i4IL1jV4k%3D; https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge%2C+Technology%2C+%26+Policy&rft.atitle=Open+source+software+and+software+patents%3A+A+constitutional+perspective&rft.au=Pfaffenberger%2C+Bryan.&rft.aulast=Pfaffenberger&rft.aufirst=Bryan&rft.date=1999-10-01&rft.volume=12&rft.issue=3&rft.spage=94&rft.isbn=&rft.btitle=&rft.title=Knowledge%2C+Technology%2C+%26+Policy&rft.issn=08971986&rft_id=info:doi/10.1007%2Fs12130-999-1029-x","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; 45411:Electronic Shopping and Mail-Order Houses; Patent; 5230:Hardware; Digital Revolution; Patent infringement","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is difficult to further enrich the features of text encoding vectors. At the same time, most existing bug report classification methods ignore the submitter's personal information. To solve these problems, we construct nine personal information characteristics of bug report submitters in GitHub by survey. Then, we propose a GitHub bug report classification method named personal information fine‐tuning network (PIFTNet) based on transfer learning and the submitter's personal information. PIFTNet transfers the general text feature vectors in bidirectional encoder representation from transformers (BERT) to the domain of bug report classification by fine‐tuning the pre‐training parameters in BERT. It also combines the text characteristics and the characteristics of the submitter's personal information to construct the classification model. In addition, we propose a two‐stage training method to alleviate the catastrophic changes in the pre‐training parameters and loss of the initially learned knowledge caused by direct training of PIFTNet. We verify the proposed PIFTNet on the dataset extracted from GitHub and empirical results prove the effectiveness of PIFTNet.","2024-05","2025-04-25 17:00:30","2025-04-25 17:00:30","","","","5","41","","","","","","","","","","English","","","ABI/INFORM Global","3032788076","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Expert+Systems&rft.atitle=Classification+of+open+source+software+bug+report+based+on+transfer+learning&rft.au=Liao+Zhifang%3BWang%2C+Kun%3BZeng+Qi%3BLiu+Shengzong%3BZhang%2C+Yan%3BHe+Jianbiao.&rft.aulast=Liao+Zhifang&rft.aufirst=&rft.date=2024-05-01&rft.volume=41&rft.issue=5&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Expert+Systems&rft.issn=02664720&rft_id=info:doi/10.1111%2Fexsy.13184","Open source software; Computers--Artificial Intelligence; Personal information; Deep learning; Classification; Mathematical models; Debugging; Coding; Datasets; Bug report classification; Parameters; Submitter's personal information; Transfer learning; Tuning","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, users often tend to acquire codes from the community and are reluctant to contribute their knowledge. Integrating the motivational theory and social capital theory, this article intends to explore users’ contribution in OSS communities. A mixed method of SEM and fsQCA was used to perform data analysis. We found that intrinsic motivations (flow experience and self-efficacy), extrinsic motivations (perceived reputation and reciprocity), social interaction ties, community identification, and common language positively affect users’ contribution intention. Trust has no effect on the contribution intention. The fsQCA results indicated that flow experience, perceived reputation, reciprocity and trust are the common core conditions of four configurations leading to contribution intention. The results suggest that OSS communities need to be concerned with users’ motivations and develop social capital in order to encourage their contribution.","2023-11","2025-04-25 17:00:30","2025-04-25 17:00:30","","1382-1393","","6","63","","","","","","","","","","English","","","ABI/INFORM Global","2884936915","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Examining+Users%26rsquo%3B+Contribution+in+Open+Source+Software+Communities&rft.au=Zhou%2C+Tao%3BYuan%2C+Qingqing.&rft.aulast=Zhou&rft.aufirst=Tao&rft.date=2023-11-01&rft.volume=63&rft.issue=6&rft.spage=1382&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2022.2155268","Open source software; Computers; contribution; Motivation; Social capital; Data analysis; Open source; Software; Open-source software; Reciprocity; fsQCA; Lingua franca; motivational theory; OSS community; Social factors","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Two amendments are proposed. First, we add a new dimension to the framework, institutional competence (“where to own”), which denotes that individuals and firms have heterogeneous abilities to assess how an institutional environment affects the potential uses of a resource. Second, we argue that institutional uncertainty moderates the three original dimensions of the framework, impairing the exercise of ownership competence of some entrepreneurs and firms more than of others. We use examples from the literature to illustrate our arguments. We also discuss the implications of our analysis.Managerial SummaryThe ownership competence framework is built on the idea that business owners have different abilities to deploy resources and create value. Starting from this contribution, we shed light on the specific role that the institutional environment plays in the exercise of ownership competence. We argue that the ownership competence framework must explicitly consider where ownership takes place in order to explain the actions of entrepreneurs and firms. We also claim that institutional uncertainty can influence value creation in more subtle ways than indicated in the original formulation of the ownership competence framework. All in all, this article paves the way for institutional aspects to be considered more explicitly in the strategic analysis of ownership.","2023-08","2025-04-25 17:00:30","2025-04-25 17:00:30","","1939-1954","","8","44","","","","","","","","","","English","","","ABI/INFORM Global","2834858422","","","Place: Chicago Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Strategic+Management+Journal&rft.atitle=Disentangling+the+role+of+the+institutional+environment+in+the+ownership+competence+framework%3A+A+comment+on+Foss+et+al.+%282021%29&rft.au=Monteiro%2C+Guilherme+Fowler+A%3BBruno+Varella+Miranda.&rft.aulast=Monteiro&rft.aufirst=Guilherme+Fowler&rft.date=2023-08-01&rft.volume=44&rft.issue=8&rft.spage=1939&rft.isbn=&rft.btitle=&rft.title=Strategic+Management+Journal&rft.issn=01432095&rft_id=info:doi/10.1002%2Fsmj.3462","Institution; Uncertainty; Business And Economics--Management; Ownership; Companies; value creation; Strategic management; Business ownership; Competence; Entrepreneurs; Frame analysis; Institutional aspects; institutional competence; institutional environment; institutional uncertainty; Owners; ownership competence; Value creation; Value proposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The flaw led to risks in software used by government agencies, Web service providers such as Amazon Web Services and Apple iCloud, and even video games such as Minecraft. The Log4J issue earned a rare rating of 10 on the Common Vulnerability Scoring System, signaling the highest level of risk, and cybersecurity experts warned the effects could be felt for years until every affected program can be secured.

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-04-25 17:00:30","2025-04-25 17:00:30","","361","","1","47","","","","","","","","","","English","","","ABI/INFORM Global","2783221355","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Resilience+in+the+Open+Source+Software+Community%3A+How+Pandemic+and+Unemployment+Shocks+Influence+Contributions+to+Others%27+and+One%27s+Own+Projects&rft.au=Malgonde%2C+Onkar+S%3BSaldanha%2C+Terence+J+V%3BMithas%2C+Sunil.&rft.aulast=Malgonde&rft.aufirst=Onkar&rft.date=2023-03-01&rft.volume=47&rft.issue=1&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2022%2F17256","Open source software; COVID-19; Computers; Resilience; Pandemics; Public health; Community; Open source; Software; Open-source software; Pandemic; Prosocial behavior; Public domain; Empirical analysis; Unemployment; Nature conservation; Resource conservation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors’ engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors’ attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023","2025-04-25 17:00:31","2025-04-25 17:00:31","","3106-3130","","5","49","","","","","","","","","","English","","","ABI/INFORM Global","2814541650","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Understanding+Mentors%26rsquo%3B+Engagement+in+OSS+Communities+via+Google+Summer+of+Code&rft.au=Tan%2C+Xin%3BZhou%2C+Minghui%3BZhang%2C+Li.&rft.aulast=Tan&rft.aufirst=Xin&rft.date=2023-01-01&rft.volume=49&rft.issue=5&rft.spage=3106&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2023.3242415","Open source software; Organizations; Mentors; Motivation; Data analysis; Students; Open-source software; Task analysis; Strategy; Mentoring; Sustainability; open source communities; Internet; Encoding; Codes; Taxonomy; Mentor; Computers--Software; taxonomy; Challenge; mentoring process; Mentorship; newcomer onboarding; summer of code","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader.

Building on existing OSS research, we explore norms with respect to collaboration, i.e., how developers assign, discuss, and complete tasks, in an orgsOSS project.

Widely shared reports indicate that gender differences may be specific to each region. However, how complete can these reports be with little to no research reflective of the Open Source Software (OSS) process and communities software is now commonly developed in? Our study presents a multi-region geographical analysis of gender inclusion on GitHub. This mixed-methods approach includes quantitatively investigating differences in gender inclusion in projects across geographic regions and investigate these trends over time using data from contributions to 21,456 project repositories. We also qualitatively understand the unique experiences of developers contributing to these projects through a survey that is strategically targeted to developers in various regions worldwide. Our findings indicate that gender diversity is low across all parts of the world, with no substantial difference across regions. However, there has been statistically significant improvement in diversity worldwide since 2014, with certain regions such as Africa improving at faster pace. We also find that most motivations and barriers to contributions (e.g., lack of resources to contribute and poor working environment) were shared across regions, however, some insightful differences, such as how to make projects more inclusive, did arise. From these findings, we derive and present implications for tools that can foster inclusion in open source software communities and empower contributions from everyone, everywhere.","2022","2025-04-25 17:00:31","2025-04-25 17:00:31","","3394-3409","","9","48","","","","","","","","","","English","","","ABI/INFORM Global","2714955135","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Including+Everyone%2C+Everywhere%3A+Understanding+Opportunities+and+Challenges+of+Geographic+Gender-Inclusion+in+OSS&rft.au=Gede+Artha+Azriadi+Prana%3BFord%2C+Denae%3BRastogi%2C+Ayushi%3BLo%2C+David%3BPurandare%2C+Rahul%3BNagappan%2C+Nachiappan.&rft.aulast=Gede+Artha+Azriadi+Prana&rft.aufirst=&rft.date=2022-01-01&rft.volume=48&rft.issue=9&rft.spage=3394&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2021.3092813","Open source software; GitHub; gender; software engineering; Software engineering; OSS; Software; Open-source software; diversity; Industries; empirical studies; Gender issues; Software development management; Europe; Public domain; Computers--Software; Industrial development; Gender; Gender aspects; Gender diversity; Gender gap; geographic regions; Geographical distribution; Inclusion; Toy manufacturing industry; Working conditions","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While this model lowers the barrier to entry for OSS developers by synthesizing, automating and optimizing the contribution process, coordination among an increasing number of contributors remains as a challenge due to the asynchronous and self-organized nature of distributed development. In particular, duplicate contributions, where multiple different contributors unintentionally submit duplicate pull requests to achieve the same goal, are an elusive problem that may waste effort in automated testing, code review and software maintenance. While the issue of duplicate pull requests has been highlighted, to what extent duplicate pull requests affect the development in OSS communities has not been well investigated. In this paper, we conduct a mixed-approach study to bridge this gap. Based on a comprehensive dataset constructed from 26 popular GitHub projects, we obtain the following findings: (a) Duplicate pull requests result in redundant human and computing resources, exerting a significant impact on the contribution and evaluation process. (b) Contributors’ inappropriate working patterns and the drawbacks of their collaborating environment might result in duplicate pull requests. (c) Compared to non-duplicate pull requests, duplicate pull requests have significantly different features, e.g., being submitted by inexperienced contributors, being fixing bugs, touching cold files, and solving tracked issues. (d) Integrators choosing between duplicate pull requests prefer to accept those with early submission time, accurate and high-quality implementation, broad coverage, test code, high maturity, deep discussion, and active response. Finally, actionable suggestions and implications are proposed for OSS practitioners.","2022","2025-04-25 17:00:31","2025-04-25 17:00:31","","1309-1335","","4","48","","","","","","","","","","English","","","ABI/INFORM Global","2650298132","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Redundancy%2C+Context%2C+and+Preference%3A+An+Empirical+Study+of+Duplicate+Pull+Requests+in+OSS+Projects&rft.au=Li%2C+Zhixing%3BYu%2C+Yue%3BZhou%2C+Minghui%3BWang%2C+Tao%3BYin%2C+Gang%3BLong%2C+Lan%3BWang%2C+Huaimin.&rft.aulast=Li&rft.aufirst=Zhixing&rft.date=2022-01-01&rft.volume=48&rft.issue=4&rft.spage=1309&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2020.3018726","Automation; Collaboration; Tools; Context; Testing; Encoding; Computer bugs; Synchronization; social coding; Project; Computers--Software; Integrators; Cloning; distributed collaboration; Duplicate pull requests; pull-based development model; Redundancy; Reproduction (copying)","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some questions are raised, such as: (1) To what extent do organizations linked with Collaborative Economy make use of Free and Open Source Software?, (2) What are the incentives that motivate the implementation of Free and Open Source Software in Collaborative Economy companies?, (3) What use do Collaborative Economy companies give to Free and Open Source Software?, and (4) Is there a greater use of Free and Open Source Software expected for the coming years among these organizations? To answer these questions, a study based on the Delphi method has been designed. To this end, a panel of 15 high-level experts in the field was formed.

For instance, open source software (OSS) is developed by mass collaboration on digital communities to provide software users free alternatives to commercial products. OSS is particularly valuable to meet the needs of numerous disadvantaged users for whom proprietary software is not affordable. While OSS projects are lack of formal organizational structure, project leaders play a significant role in initiating and managing these projects and eventually, influencing the degree to which the developed software is used and liked by users. Drawing on resource dependence theory, we investigate the impacts of two team‐level characteristics of OSS project leaders (ie, size and tenure) on how well the developed software can address users' needs, with regard to the quantity of software being used by users and the quality of software to users' satisfaction. Further, from a resource dependence perspective, we examine the moderating role of project leaders' network ties in shaping the contingency of these effects. By using a large‐scale dataset from 43 048 OSS development projects in SourceForge community, we find empirical evidence corroborating our theory. Taken together, our findings suggest the boundary‐spanning role of project leaders in developing digital social innovation.","2021-09","2025-04-25 17:00:31","2025-04-25 17:00:31","","672-694","","5","31","","","","","","","","","","English","","","ABI/INFORM Global","2559383916","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=Project+leaders+as+boundary+spanners+in+open+source+software+development%3A+A+resource+dependence+perspective&rft.au=John+Qi+Dong%3BG%C3%B6tz%2C+Sebastian+Johannes.&rft.aulast=John+Qi+Dong&rft.aufirst=&rft.date=2021-09-01&rft.volume=31&rft.issue=5&rft.spage=672&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12313","Open source software; Open source; software development; open source software; Open-source software; resource dependence theory; social innovation; Computers--Computer Systems; Software development; Public domain; Freeware; Project; Innovations; Organizational structure; User satisfaction; Contingency; digital innovation; project leaders; Resource dependence theory; Social innovation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-player game and examine how open-source licensing affects competition among an open-source originator, an open-source contributor, and a proprietor competing in an enterprise software market. In this regard, we examine (1) how quality investments and prices are endogenously determined in equilibrium, (2) how license restrictiveness impacts equilibrium investments and the quality of offerings, and (3) how license restrictiveness affects consumer surplus and social welfare. Although some in the open-source community often advocate restrictive licenses such as the GNU General Public License because it is not always in the best interest of the originator for the contributor to invest greater development effort, such licensing can actually be detrimental to both consumer surplus and social welfare when it exacerbates this incentive conflict. We find such an outcome in markets characterized by software providers with similar development capabilities yet cast in favor of the proprietor. In contrast, when these capabilities either become more dispersed or remain similar but tilt in favor of open source, a more restrictive license instead encourages greater effort from the OSS contributor, leads to higher OSS quality, and provides a larger societal benefit.","2021-05","2025-04-25 17:00:31","2025-04-25 17:00:31","","3041","","5","67","","","","","","","","","","English","","","ABI/INFORM Global","2536540439","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+Science&rft.atitle=Competition+Among+Proprietary+and+Open-Source+Software+Firms%3A+The+Role+of+Licensing+in+Strategic+Contribution&rft.au=August%2C+Terrence%3BChen%2C+Wei%3BZhu%2C+Kevin.&rft.aulast=August&rft.aufirst=Terrence&rft.date=2021-05-01&rft.volume=67&rft.issue=5&rft.spage=3041&rft.isbn=&rft.btitle=&rft.title=Management+Science&rft.issn=00251909&rft_id=info:doi/10.1287%2Fmnsc.2020.3674","Open source software; Software; Open-source software; Licenses; Incentives; Companies; Competition; Game theory; Markets; Public domain; Licensing; Business And Economics--Labor And Industrial Relations; Prices; Best interests; Economic value added; Equilibrium; Social welfare","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

What is the nature of these novel arrangements? Does volunteers’ participation remain critical for these ecosystems? Despite extensive research on commercial participation in OSS, the exact nature and extent of company contributions to OSS development, and the impact of this engagement may have on the volunteer community have not been clarified. To bridge the gap, we perform an exploratory study of OpenStack: a large OSS ecosystem with intense commercial participation. We quantify companies’ contributions via the developers that they provide and the commits made by those developers. We find that companies made far more contributions than volunteers and the distribution of the contributions made by different companies is also highly unbalanced. We observe eight unique contribution models based on companies’ commercial objectives and characterize each model according to three dimensions: contribution intensity, extent, and focus. Companies providing full cloud solutions tend to make both intensive (more than other companies) and extensive (involving a wider variety of projects) contributions. Usage-oriented companies make extensive but less intense contributions. Companies driven by particular business needs focus their contributions on the specific projects addressing these needs. Minor contributors include community players (e.g., the Linux Foundation) and research groups. A model relating the number of volunteers to the diversity of contribution shows a strong positive association between them.","2021","2025-04-25 17:00:31","2025-04-25 17:00:31","","2242-2259","","10","47","","","","","","","","","","English","","","ABI/INFORM Global","2582248219","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Companies%26rsquo%3B+Participation+in+OSS+Development%26ndash%3BAn+Empirical+Study+of+OpenStack&rft.au=Zhang%2C+Yuxia%3BZhou%2C+Minghui%3BMockus%2C+Audris%3BJin%2C+Zhi.&rft.aulast=Zhang&rft.aufirst=Yuxia&rft.date=2021-01-01&rft.volume=47&rft.issue=10&rft.spage=2242&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2019.2946156","Open source software; Cloud computing; software development; Software engineering; Software; Open-source software; Linux; Ecosystems; Companies; Biological system modeling; Computers--Software; Open source ecosystem; Company; commercial participation; contribution extent; contribution focus; contribution intensity; Openstack","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research investigates the variety of work practices used in public communication channels by company contributors to engage with and contribute to eight community OSS projects. Through interviews with contributors to the eight projects we draw on their experiences and insights to explore the motivations to use particular methods of contribution. We find that companies utilise work practices for contributing to community projects which are congruent with the circumstances and their capabilities that support their short- and long-term needs. We also find that companies contribute to community OSS projects in ways that may not always be apparent from public sources, such as employing core project developers, making donations, and joining project steering committees in order to advance strategic interests. The factors influencing contributor work practices can be complex and are often dynamic arising from considerations such as company and project structure, as well as technical concerns and commercial strategies.

Despite its ubiquity, there is a lack of empirical evidence to validate the relative position of each task cluster within the onion model. In this study, we map out the community structure of a large open source project and observe its bug‐fixing patterns to explore the relationship between tasks and structure. Our study makes three significant contributions. First, we find no empirical evidence to support the structural location of bug‐fixing tasks in the onion structure. Second, we find empirical evidence to support the core‐periphery continuum model linking an actor’s coreness to problem‐solving ability. Third, our results suggest that the importance and location of each task within the core‐periphery structure evolve over time.

While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-04-25 17:00:32","2025-04-25 17:00:32","","369-402","","2","30","","","","","","","","","","English","","","ABI/INFORM Global","2352536913","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+Third+Design+Space%3A+A+postcolonial+perspective+on+corporate+engagement+with+open+source+software+communities&rft.au=Kendall%2C+Kenneth+E%3BKendall%2C+Julie+E%3BGermonprez%2C+Matt%3BMathiassen%2C+Lars.&rft.aulast=Kendall&rft.aufirst=Kenneth&rft.date=2020-03-01&rft.volume=30&rft.issue=2&rft.spage=369&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fisj.12270","Open source software; Collaboration; Open source; software development; open source software; Open-source software; metaphor; Computers--Computer Systems; Software development; Public domain; Qualitative analysis; Metaphor; Cultivation; postcolonialism; Postcolonialism; Third Design Space; third space; Throttles","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-04-25 17:00:32","2025-04-25 17:00:32","","764","","3","30","","","","","","","","","","English","","","ABI/INFORM Global","2307721543","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Does+Superposition+Influence+the+Success+of+FLOSS+Projects%3F+An+Examination+of+Open-Source+Software+Development+by+Organizations+and+Individuals&rft.au=Medappa%2C+Poonacha+K%3BSrivastava%2C+Shirish+C.&rft.aulast=Medappa&rft.aufirst=Poonacha&rft.date=2019-09-01&rft.volume=30&rft.issue=3&rft.spage=764&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2018.0829","Open source software; Organizations; Motivation; Open source; Software engineering; Open-source software; Computer architecture; Ownership; Success; Computers--Information Science And Information Theory; Project management; Software development; Freeware; 51821:Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services; Modular design; Project Success; Superposition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person–environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity. We discuss the implications of our findings for research and practice.","2019-09","2025-04-25 17:00:32","2025-04-25 17:00:32","","951","","3","43","","","","","","","","","","English","","","ABI/INFORM Global","2283390283","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Developer+Centrality+and+the+Impact+of+Value+Congruence+and+Incongruence+on+Commitment+and+Code+Contribution+Activity+in+Open+Source+Software+Communities&rft.au=Maruping%2C+Likoebe+M%3BDaniels%2C+Sherae+L%3BCataldo%2C+Marcelo.&rft.aulast=Maruping&rft.aufirst=Likoebe&rft.date=2019-09-01&rft.volume=43&rft.issue=3&rft.spage=951&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2019%2F13928","Open source software; Uncertainty; Computers; Collaboration; Open source; Software; Open-source software; Regression analysis; Social networks; Commitment; Public domain; Developer; Impact fees; Congruence; Polynomials","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The authors draw on a case study of the ‘Heidi bug’ discovered during the development of the Mozilla Firefox web browser to examine how ‘gendered talk’ was (en)‐acted to facilitate ‘bricolage’ in an online work environment. Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender‐balanced, women‐friendly and inclusive workplace certainly would benefit from a more diverse environment. This article highlights the gendered aspect of software development through examining the language use and mainstream ‘bricolage’ practice, and establishes a compelling ground for enlarging the talent pool to include more women and integrating gender ethics (e.g., raising awareness of sensitive language and design approaches) into computer ethics education.","2019-07","2025-04-25 17:00:32","2025-04-25 17:00:32","","1017-1031","","7","26","","","","","","","","","","English","","","ABI/INFORM Global","2257969279","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Gender%2C+Work+and+Organization&rft.atitle=Gendered+work+culture+in+free%2Flibre+open+source+software+development&rft.au=Yu%E2%80%90Wei+Lin%3Bden+Besten%2C+Matthijs.&rft.aulast=Yu%E2%80%90Wei+Lin&rft.aufirst=&rft.date=2019-07-01&rft.volume=26&rft.issue=7&rft.spage=1017&rft.isbn=&rft.btitle=&rft.title=Gender%2C+Work+and+Organization&rft.issn=09686673&rft_id=info:doi/10.1111%2Fgwao.12255","Open source software; Ethics; Qualitative research; Masculinity; Women; Business And Economics--Management; open innovation; Software; Feminism; Case studies; Internet; Software development; Case study; Public domain; Freeware; Property; Corporate culture; Free; Work environment; Consciousness; Computer ethics; Gender; Ability; Bricolage; Cultural change; free/libre open source software; gendered talks; Hegemony; heterohegemonic masculinity; Heterosexuality; humour; Ignorance; Language usage; Moral education; online virtual work space; Organizational culture; work cultures; Workplaces","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The studied branch focuses on developing Android phones. This paper presents contribution strategies and triggers for openness. These strategies include avoid forking OSS tools, empower developers to participate in the ecosystem, steer ecosystems through contributions, create business through differentiation, and create new ecosystems.

Knowledge can be shared among individuals, groups, and organizations. A free software community is a type of community of practice arranged around a specific free software, where the knowledge shared is complex and the knowledge sharing processes have scarcely been studied. This investigation aims to identify the profiles of knowledge sharing processes in free software communities and examine how 6 motivations for sharing knowledge in free software communities are associated with each of the clusters. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters were identified: Sporadic Sharer; Collector; Donator; and Constant Sharer. With the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators and Collectors. These results confirm the view of free software communities as communities of practice and highlight the importance of knowledge sharing in free software development cycle. The results reveal the importance of the Constant Sharer profile, which has the highest rates of donation and collection and is also the profile in which all the motivations appear with the highest values, indicating its key role in the functioning of free software communities.","2018-09","2025-04-25 17:00:32","2025-04-25 17:00:32","","143-152","","3","25","","","","","","","","","","English","","","ABI/INFORM Global","2082030930","","","Place: Chichester Publisher: Wiley Periodicals Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Knowledge+and+Process+Management&rft.atitle=The+life+cycle+process+of+knowledge+sharing+in+free+software+communities%3A+Sharing+profiles+and+motivations&rft.au=Balle%2C+Andrea+Raymundo%3BOliveira%2C+M%C3%ADrian.&rft.aulast=Balle&rft.aufirst=Andrea&rft.date=2018-07-01&rft.volume=25&rft.issue=3&rft.spage=143&rft.isbn=&rft.btitle=&rft.title=Knowledge+and+Process+Management&rft.issn=10924604&rft_id=info:doi/10.1002%2Fkpm.1569","Motivation; Business And Economics--Management; Software; Knowledge sharing; Free software; Software development; Freeware; Life cycle engineering; Communities of practice; Cluster analysis; Community of practice; Intellectual capital","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some others have investigated knowledge management among open-source-software (OSS) developers and discussed factors influencing knowledge transfer within development teams (e.g. Joshi and Sarker, 2006). In the domain of open source software (OSS) communities, more companies are now attempting to establish relationships to benefit from these potential value-creating communities; and project managers could in fact target different goals within software development teams including knowledge transfer within and between teams. We step forward to distinguish knowledge transfer within groups as opposed to knowledge transfer between groups; where relevant projects are bundled into separate strongly intra-connected groups. In knowledge management literature there is a trade-off between sparse network structures (Burt, 2000, 2002) versus dense network structures (Walker et al., 1997; Coleman, 1988). It is argued that the former facilitates the diffusion and generation of ideas among groups, while the latter affects the implementation of idea within each dense group. To our best knowledge, there has been no study to investigate the relationship between dense and sparse network structures. We propose that knowledge transfer within dense groups has a positive influence on knowledge transfer between sparse groups, in that intragroup density, group size, developers centrality and betweenness could impact intergroup coupling. To prove our hypothesis, we use a complex network of open source software (OSS) as the domain of interest, where developers represent nodes and two developers contributing to a project task represent a network tie. Developers contributing to tasks in groups other than their own can explore novel ideas via sharing knowledge, whereas developers contributing to tasks inside groups exploit ideas to improve those projects. We investigate the idea both analytically and empirically within 4 months, 8 months and 1 year lagged time, and finally show that intragroup density has a positive whereas developers’ centrality has a negative influence on intergroup coupling.","2018-02","2025-04-25 17:00:32","2025-04-25 17:00:32","","167","","1","38","","","","","","","","","","English","","","ABI/INFORM Global","2048526571","","","Place: Kidlington Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Management&rft.atitle=Knowledge+management+in+OSS+communities%3A+Relationship+between+dense+and+sparse+network+structures%3A+SSIS&rft.au=Behfar%2C+Stefan+Kambiz%3BTurkina%2C+Ekaterina%3BBurger-Helmchen%2C+Thierry.&rft.aulast=Behfar&rft.aufirst=Stefan&rft.date=2018-02-01&rft.volume=38&rft.issue=1&rft.spage=167&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Management&rft.issn=02684012&rft_id=info:doi/","Open source software; Community; Knowledge transfer; Open-source software; Knowledge management; Knowledge sharing; Information sharing; Centrality; Software development; Coupling; Public domain; 23721:Land Subdivision; Developers; Social Sciences: Comprehensive Works; Betweenness; Source code; Sparse network","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS. Cependant, ces recherches se sontprincipalement concentrées sur des projets reconnus et de grande envergure, tels que Linux ou Apache. Une investigation des projets moins connus permettrait une compréhension plus complete et d'éviter un taux d'échec important des projets OSS. Cette étude investigue donc la combi- naison de trois facteurs : les interactions des utilisateurs et développeurs, la pénétration du marché et le stade de développement, afin d'observer leur impact sur la popularité des projets OSSpeu connus. Nous a vons pour cela développé un modele empirique de la popularité des OSS, et avons testé nos hypotheses sur 657projets de logiciel libre.

The hypotheses are evaluated by means of an econometric model of simultaneous equations. In order to better gauge the results of the hypotheses, the model is evaluated over economic environments at different stages of development. Social development and OSS growth were found to be the most important facilitators for eGovernment maturity, across countries of all stages of development. Institutional quality, technological openness, freedom in press and the macro-economic environment exerted different weights of importance across different country groupings. Findings also suggest that technological infrastructure and innovation are important drivers for OSS growth across countries at all stages of development.

However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.","2015","2025-04-25 17:00:33","2025-04-25 17:00:33","","116","","1","32","","","","","","","","","","English","","","ABI/INFORM Global","1697517813","","","Place: Abingdon Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Management+Information+Systems&rft.atitle=Exploitation+and+Exploration+Networks+in+Open+Source+Software+Development%3A+An+Artifact-Level+Analysis%3A+JMIS&rft.au=Temizkan%2C+Orcun%3BKumar%2C+Ram+L.&rft.aulast=Temizkan&rft.aufirst=Orcun&rft.date=2015-07-01&rft.volume=32&rft.issue=1&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Journal+of+Management+Information+Systems&rft.issn=07421222&rft_id=info:doi/","Open source software; Political Science; Studies; Open source; Software engineering; Software; Open-source software; Success; Social networks; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Exploitation; Exploration","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual developers contribute to developing the software, but do not hold the copyright to appropriate its value. This raises questions regarding motives behind such effort. We provide an integrated model of developers' incentives to describe OSS development and compare restrictive OSS licenses that force all modifications to be kept open with non-restrictive OSS licenses that allow proprietary ownership of modified works. Different incentives govern effort provision at different stages of the software development process. We show that open-source licenses can provide socially valuable software when a proprietary license fails to do so. We also show that restrictive OSS licenses generate greater effort provision in the design stage of software development relative to non-restrictive licenses. Endogenizing licensing choice, we find that a project leader chooses a non-restrictive OSS license if reputational concerns drive developers' incentives, a proprietary license when there is a large population of users in the market and a restrictive OSS license if user population is small but reputational benefit is high. Our results resonate well with empirical findings and suggest additional testable implications about the relationship between licensing and software project characteristics. Finally, we also find that the market under-provides restrictive OSS licenses relative to the efficient level, suggesting the need for subsidizing restrictive licenses in some cases.","2015-07","2025-04-25 17:00:33","2025-04-25 17:00:33","","1381","","3","15","","","","","","","","","","English","","","ABI/INFORM Global","1693624750","","","Place: Berkeley Publisher: Berkeley Electronic Press","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+B.E.+Journal+of+Economic+Analysis+%26+Policy&rft.atitle=Developers%27+Incentives+and+Open-Source+Software+Licensing%3A+GPL+vs+BSD&rft.au=Atal%2C+Vidya%3BShankar%2C+Kameshwari.&rft.aulast=Atal&rft.aufirst=Vidya&rft.date=2015-07-01&rft.volume=15&rft.issue=3&rft.spage=1381&rft.isbn=&rft.btitle=&rft.title=The+B.E.+Journal+of+Economic+Analysis+%26+Policy&rft.issn=21946108&rft_id=info:doi/","Open source software; Studies; Open source; Software engineering; Software license; Open-source software; Licenses; License; Software development; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; Developer; Proprietary; Licensing; 1130:Economic theory; Public good; Business And Economics--Economic Systems And Theories, Economic History; Economic models; Incentive","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This increasing attention is a result of the remarkable growth in the number of OSS applications in recent years. Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1,409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest. These findings have implications for both the OSS research community and OSS practitioners.","2015","2025-04-25 17:00:33","2025-04-25 17:00:33","","28","","1","25","","","","","","","","","","English","","","ABI/INFORM Global","1654703565","","","Place: Mahwah Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.atitle=Investigating+the+Interrelationships+among+Success+Measures+of+Open+Source+Software+Projects&rft.au=Ghapanchi%2C+Amir+Hossein.&rft.aulast=Ghapanchi&rft.aufirst=Amir&rft.date=2015-01-01&rft.volume=25&rft.issue=1&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.issn=10919392&rft_id=info:doi/","Open source software; Studies; Open source; Software; Open-source software; Success; Sustainability; Project management; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Software Projects; Project Success; Business And Economics--Computer Applications; Management theory; Release management; Sustainability management","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. They also reproduced the results on new data provided by Mozilla. The authors constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants.

Currently, there exists no working operationalization available that can be used to determine the health of open source ecosystems. Health is typically looked at from a project scope, not from an ecosystem scope. With such an operationalization, stakeholders can make better decisions on whether to invest in an ecosystem: developers can select the healthiest ecosystem to join, keystone organizers can establish which governance techniques are effective, and end-users can select ecosystems that are robust, will live long, and prosper. Design research is used to create the health operationalization. The evaluation step is done using four ecosystem health projects from literature. The Open Source Ecosystem Health Operationalization is provided, which establishes the health of a complete software ecosystem, using the data from collections of open source projects that belong to the ecosystem. The groundwork is done, by providing a summary of research challenges, for more research in ecosystem health.

We propose a methodology -- based on situated analyses of a formal design process used in the Python project -- to identify the distribution of actual roles (implementation, interactive, group, and design oriented) performed by participants into and between the spaces (defining boundary spaces). This notion of roles is grounded in collaborative design activities performed online by participants. This way, our findings complete the core-periphery model of participation in OSS. Concerning the distribution of roles between spaces, we reveal a map of participation in OSS: The majority of participants are pure discussants, but all participants in the implementation spaces do also act in the discussion space, and few participants act at boundary spaces. Concerning the distribution of roles between participants in the discussion space, we reveal that interactions are structured by a central hub (occupied by key participants) and that, whereas design-oriented roles are spread among all participants, group-oriented roles are performed by one or two participants in the respective spaces and at their boundary. Finally, combination of roles reveals five individual profiles performed by participants. Our approach could be extended to other design situations to explore relationships between forms of participation -- in particular, those revealing use-oriented contributions -- performance, and quality of the design product. Finally, it could be a basis for specifying tools to monitor and manage community activity for both research issues and support of online community.

Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (0395 and 0400), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that -- (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described.

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving.

While prior research has explored the communal nature of open source software development among individual users, little research has explored whether these sharing concepts are also present in organizational use of open source software products. This study uses a theory integration approach to develop some initial insight into the differences between users and non-users of open source software. This study observed three groups of factors from six case studies of information sharing in the context of organizational open source software use. These factors were integrated with prior research in order to understand the physical and managerial barriers to, and enablers of, open source. The study proposes that open source users have more extensive knowledge sharing and teamwork practices in place, and are more tolerant of risk. The study also argues that open source users depended less on external technology support services but have more extensive information technology (IT) support structures.

Three configurations were identified: Defined Community, Open Community, and Authoritarian Community. Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team. The results provide guidance for practitioners about how to combine 19 identified governance mechanisms into effective project governance that stimulates productive participation.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented.

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice. Our research sheds new light on our understanding of license choice for OSS projects and provides practical guidelines for future OSS development.

Using detailed data collected from code repositories from SoureForge.com, we find that developer team structure and software architecture significantly moderate each other's effect on OSS development performance. Larger teams tend to produce more favorable project performance when the project being developed has a high level of structural interdependency while projects with a low level of structural interdependency require smaller teams in order to achieve better project performance. Meanwhile, centralized teams tend to have a positive impact on project performance when the OSS project has a high level of structural interdependency. However, when a project has a low level of structural interdependency, centralized teams can impair project performance. This study extends our understanding of information technology's deep engagement in organizational life and provides directions for open source practitioners to better organize their projects to achieve greater performance.

Recent examples appear to lend support to this, but there exist many detractors of OSS and resistance to the transformation it creates. Thus, it is relevant to take a closer look at the institutionalization of OSS. This paper evaluates the extent of OSS institutionalization in organizations. A practice or innovation is said to be institutionalized when it is taken-for-granted and its use becomes the norm. Drawing on institutional theory, the underlying concept of organizing vision and the rhetorical theory of diffusion of innovations, the authors analyze OSS institutionalization through the observation of the evolution of the public discourse about OSS and, simultaneously, the observation of the rate of adoption or diffusion of OSS in organizations.","2012-12","2025-04-25 17:00:35","2025-04-25 17:00:35","","1308","","12","54","","","","","","","","","","English","","","ABI/INFORM Global","1037945028","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Has+open+source+software+been+institutionalized+in+organizations+or+not%3F&rft.au=Marsan%2C+Josianne%3BPar%C3%A9%2C+Guy%3BWybo%2C+Michael+D.&rft.aulast=Marsan&rft.aufirst=Josianne&rft.date=2012-12-01&rft.volume=54&rft.issue=12&rft.spage=1308&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Institutionalization; Studies; Open source; Software engineering; Open-source software; Organizing vision; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Technological change; Organization theory; Computers--Data Base Management; Diffusion of innovations; Institutionalisation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, few studies have focused on the start-ups that enter the market just to exploit the new business opportunities stemming from the freely available technological knowledge developed by the FLOSS community (FLOSS-based start-ups). This paper aims to fill this gap by providing descriptive evidence about these firms. We address two main research questions: 1) What are the main features of FLOSS-based start-ups?; 2) What is their innovation process? We show that FLOSS-based start-ups follow a typical open innovation model that enables them to serve market niches that large incumbents are not structurally able to cover, profiting from the local production, distribution, and use of technological knowledge.

Developing these resources can be expensive and time consuming. Even when data and tools are intended for public re-use they often come with technical, legal, economic and social barriers that make them difficult to adopt, adapt and combine for use in new contexts. We focus on the promise of open, publically accessible software and data as well as crowdsourcing techniques to develop robust energy analysis tools that can deliver crucial, policy-relevant insight, particularly in developing countries, where planning resources are highly constrained -- and the need to adapt these resources and methods to the local context is high. We survey existing research, which argues that these techniques can produce high-quality results, and also explore the potential role that linked, open data can play in both supporting the modelling process and in enhancing public engagement with energy issues.

The presence of effective leaders who both steer the development and motivate the developers is crucial to ensure a successful product. Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

In empirical organizational research, the analysis of two-mode networks is typically accomplished either by (a) decomposition of the dual structure into its two unimodal components defined in terms of indirect relations between entities of the same kind or (b) direct statistical analysis of individual two-mode dyads. Both strategies are useful, but neither is fully satisfactory. In this article, the authors introduce newly developed stochastic actor-based models for two-mode networks that may be adopted to redress the limitations of current analytical strategies. The authors specify and estimate the model in the context of data they have collected on the dual association between software developers and software problems observed during a complete release cycle of an open source software project. The authors discuss the general methodological implications of the models for organizational research based on the empirical analysis of two-mode networks.

In this paper, I use evidence from the United States and Canada to examine the distribution of these benefits and costs. I argue that although the rhetoric surrounding OSS is supported empirically, the benefits of OSS have been limited because of the way this technological project has evolved within its associated policy environment. That is, although ostensibly neutral, the policies and laws of both the U.S. and Canadian governments have tended to be positioned implicitly against the use of OSS both in the public sector and in the economy generally. In addition, OSS use and development requires a set of skills that are absent in many instances or create prohibitively high costs. Thus OSS is typically used by larger organizations, and its development is restricted to a mostly male, highly educated, high-income group of contributors. Therefore while the benefits of OSS are real, the distribution of these benefits is skewed.

To benefit from this opportunity, it is important to understand the strategic factors and future trends that affect the development of an efficient FLOSS economy in developing countries. This paper aims to examine the strategic factors and future trends that are likely to affect the development and deployment of FLOSS in Turkey. Based on the internal and external factors identified through the practice of technological foresight, a SWOT analysis will be carried out to identify the strengths, weaknesses, opportunities and threats for Turkey in creating a competitive software industry that can benefit from the advantages of FLOSS. Accordingly, with regard to the required technical infrastructure, an innovative/competitive business climate, skilled human resources and support for institutional structures, policy suggestions are outlined here that could be usefully implemented by government, industry and universities.

The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Following an initial systematic literature review to generate seed category data constructs, the authors performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source.

This in turn is influenced by three types of social capital - relational capital, cognitive capital and structural capital. In addition, this study also examines two moderating effects - the impact of technical complexity on the relationship between cognitive capital and expertise integration, and of task interdependence on the relationship between expertise integration and task completion. Through a field survey of 160 OSS members from five Taiwanese communities, there is support for some of the proposed hypotheses. Both reciprocity and centrality affect expertise integration as expected, but the influence of commitment and cognitive capital (including expertise and tenure) on expertise integration is not significant. Finally, expertise integration affects both team size and team effort, which in turn jointly influence task completion. This research contributes to advancing theoretical understanding of the effectiveness of free OSS development as well as providing OSS practitioners with insight into how to leverage social capital for improving the performance of OSS development.","2011-03","2025-04-25 17:00:36","2025-04-25 17:00:36","","195-219","","2","21","","","","","","","","","","English","","","ABI/INFORM Global","848569202","","","Place: Oxford Publisher: Blackwell Publishing Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Journal&rft.atitle=The+factors+that+affect+the+performance+of+open+source+software+development+-+the+perspective+of+social+capital+and+expertise+integration&rft.au=Chou%2C+Shih-Wei%3BHe%2C+Mong-Young.&rft.aulast=Chou&rft.aufirst=Shih-Wei&rft.date=2011-03-01&rft.volume=21&rft.issue=2&rft.spage=195&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Journal&rft.issn=13501917&rft_id=info:doi/10.1111%2Fj.1365-2575.2009.00347.x","Open source software; Social capital; Studies; Open source; Open-source software; Computers--Computer Systems; Software development; 5240:Software & systems; Public domain; 9130:Experimental/theoretical; Effectiveness; Relational capital; Structural capital","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ''joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.

The motivation behind individuals participating in oss projects can be, among others, social, ideological, hedonistic, or signaling, while companies gain from their access to high-quality, innovative projects and an increase in their reputation and visibility. Nowadays many business models rely on oss as a product through the provision of associated services, or in coexistence with proprietary software, hardware, services, or licensing. The numerous oss licenses mainly differ on how they treat derived software: some contain provisions that maintain its availability in open source form while others allow more flexibility. Through its widespread adoption, oss is affecting the software industry, science, engineering, research, teaching, the developing countries, and the society at large through its ability to democratize technology and innovation.","2011","2025-04-25 17:00:37","2025-04-25 17:00:37","","187-347","","3-4","4","","","","","","","","","","English","","","ABI/INFORM Global","2695489045","","","Place: Hanover Publisher: Now Publishers Inc","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.atitle=Open+Source+Software%3A+A+Survey+from+10%2C000+Feet&rft.au=Androutsellis-Theotokis%2C+Stephanos%3BSpinellis%2C+Diomidis%3BKechagia%2C+Maria%3BGousios%2C+Georgios.&rft.aulast=Androutsellis-Theotokis&rft.aufirst=Stephanos&rft.date=2011-01-01&rft.volume=4&rft.issue=3-4&rft.spage=187&rft.isbn=&rft.btitle=&rft.title=Foundations+and+Trends+in+Technology%2C+Information+and+Operations+Management&rft.issn=15719545&rft_id=info:doi/10.1561%2F0200000026","Open source software; Leadership; Information systems; Open source; Software engineering; Software license; Software; Open-source software; Psychology; Operations management; Computers--Information Science And Information Theory; Information management; Software development; Public domain; Freeware; Source code; Developing countries--LDCs; Software distribution; Proprietary software; Engineering education; Licensing (technology); Software licenses; Visibility","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at SourceForge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects.

This article considers the dynamics of value creation fuelling the proliferation of OSS and examines the business model factors that enable value capture. After interviewing leaders from over 20 OSS firms and organisations through early 2006, we found that three factors were consistently important in defining a vendor's adoption of a given business model: software licence choice, which takes into account intellectual property ownership; management of developer communities; and the unique features of the markets and product categories in which the vendor participates. Considering these factors, we characterise seven business models. One striking finding is that it is rare to find business-model purity. The majority of firms in our sample are pursuing either blended business models or multiple models simultaneously.

In this paper we examine how these employees' dual allegiance influences their knowledge sharing behaviour. We adopt Husted and Michailova's model on dual allegiance and knowledge sharing in inter-firm R&D collaborations to the context of open source software firms. We argue that the type of allegiance the individual holds towards their employing firm and the open source community has a strong influence of how they share knowledge with other community members. We use the examples of two open source software firms in New Zealand to ground the empirical inspiration of our paper and to illustrate our key ideas and arguments. We discuss the knowledge governance challenges imposed by employees' dual allegiance and how managers of open source software firms can balance the demands of the open source community and the interests of the clients.

The HFOSS Project has expanded from its three initial schools, single corporate partner, and single software project into a vibrant community that today includes active faculty participants from eight US colleges and universities (and expressed interest from many more), industry representatives from five IT corporations, and ongoing software-development projects with two local nonprofit organizations and five international FOSS communities.","2009-08","2025-04-25 17:00:37","2025-04-25 17:00:37","","67","","8","52","","","","","","","","","","English","","","ABI/INFORM Global","237057193","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Revitalizing+Computing+Education+Through+Free+and+Open+Source+Software+for+Humanity&rft.au=Morelli%2C+Ralph%3BTucker%2C+Allen%3BDanner%2C+Norman%3Bde+Lanerolle%2C+Trishan+R%3BEllis%2C+Heidi+JC%3BIzmirli%2C+Ozgur%3BKrizanc%2C+Danny%3BParker%2C+Gary.&rft.aulast=Morelli&rft.aufirst=Ralph&rft.date=2009-08-01&rft.volume=52&rft.issue=8&rft.spage=67&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/","Open source software; Students; Software; Software development; 5240:Software & systems; Public domain; Software project management; United States--US; 9190:United States; Projects; 8306:Schools and educational services; College students; 61131:Colleges, Universities, and Professional Schools; Colleges & universities; Computers--Data Communications And Data Transmission Systems; Objectives; Progress","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most studies, based on a popular FLOSS repository (SourceForge), have concluded that the vast majority of projects are failures. This study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities are formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: ""situated learning"" (the process of acting knowledgeably and purposefully in the world) and ""identity construction"" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.

However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives - voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study 1 investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization.

As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.

However, different software systems follow different strategies to evolve, affecting both the release plan and the quality of these systems. In this paper, software evolution is considered as a self-organization process and the difference between closed-source software and open-source software is discussed in terms of self-organization. In particular, an empirical study of the evolution of Linux from version 2.4.0 to version 2.6.13 is reported. The study shows how open-source software systems self-organize to adapt to functional requirements and quality requirements.

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

Building on information from an extensive dataset of secondary sources and 30 in-depth interviews, I show that de novo entrants have emerged in conjunction with a changing institutional infrastructure and a more pragmatic attitude toward firms that focus on technological benefits rather than ideology. To understand how these firms try to harness the work of these communities, I use the empirical data to derive a 2*2 matrix of different approaches. The X axis reflects whether or not the firms initiated a new community or relied on communities founded by peers, whereas the Y axis represents the degree of participation of the firm in the community. This taxonomy illustrates how de novo entrants are initiating new forms of communities or joining communities established by peers. This suggests that while many of the central pillars of FOSS remains, de novo entrants have emerged to find new ways of making business resulting in various implications for firm strategies and knowledge disclosure.

This manifests itself in the ability of open source communities to encourage critical peer review and the sharing of ideas. When these activities are important, the open source organizational form may do better than a proprietary organizational form. My results suggest why open source is particularly powerful when maintainability of software is critical, and also suggest that the founder of a software project may be more likely to choose open source if there is an existing dominant proprietary software project.

One way to achieve these ends is to implement eGovernment using free or open source software (FOSS). This will reduce dependence on software owned by major companies in developed countries. It could also promote an IP generating capacity in developing countries. An examination of the status of free or open source software in developing countries in Southeast Asia reveals that governments in these countries are aware of FOSS and wish to foster its use (but face considerable pressure to use proprietary software). This examination also reveals the presence of small but active groups seeking to develop and promote the use of free or open source software. This article is comprised of a discussion of FOSS (including that suitable for eGovernment), an explanation of the importance of FOSS for developing countries, a justification of governments centrality to the introduction of FOSS and a consideration of policies and initiatives undertaken by governments in developing countries in Southeast Asia.

From a constructionist perspective, the democratic effects of non-proprietary software are contingent on how the practice of free and open-source software is discursively represented and constituted as it is translated into new e-government systems. On these premises, an analysis of official discourse and government policy for non-proprietary software suggests that its introduction into government will bring more politics as usual rather than democratisation. Nevertheless, on the basis of an alternative discourse of ethics and freedom evident in the Free Software and Open Source communities, the authors of this paper envisage circumstances in which the discourse and practice of non-proprietary software contribute to opening-up and democratising e-government, by protecting and extending transparency and accountability in e-governments and by offering scope for technology to be shaped by citizens and associations as well as by administrators and private interests.

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-04-25 17:00:39","2025-04-25 17:00:39","","","","2","48","","","","","","","","","","English","","","ABI/INFORM Global","237056523","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Open+source+software+for+medical+image+processing+and+visualization&rft.au=Yoo%2C+Terry+S%3BAckerman%2C+Michael+J.&rft.aulast=Yoo&rft.aufirst=Terry&rft.date=2005-02-01&rft.volume=48&rft.issue=2&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/10.1145%2F1042091.1042120","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Research & development--R&D; United States--US; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Computers--Data Communications And Data Transmission Systems; Digital image processing; Image; Medical imaging","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Previous studies primarily touched on user activities in a few well-known open source projects but lack the empirical data to represent important issues facing the open source development community. This paper reports on a survey-based study that investigated user collaboration in open source development. Among the many interesting results, we found open source users themselves to be very experienced software developers. They are highly motivated to make their own contributions, work closely with developers on various tasks, and use electronic communication tools extensively. Users with different development experience and contributing to different category of projects tend to exhibit different motivations and behaviours. These findings confirm the differences between traditional and open source user collaboration and their implications for future open source evolution and management are given and discussed in this paper.

Working with data from the Apache and Mozilla projects, the study focuses on three aspects of open-source development. The first is the use of the open-source approach as a hedge against system complexity. The second is the adaptive learning mechanisms realized by the debugging process. The last is the learning curve effects of project-specific experience on bug cycle times. The results indicate that while open-source development is subject to positive learning effects, these effects are not universal, with some projects deriving more benefit than others.

First, the movement took off through the activity of a community that did not follow profit motivations. Second, a hierarchical co-ordination emerged without proprietary rights. Third, Open Source systems diffused in environments dominated by proprietary standard. The paper shows that recent developments in the theory of diffusion of technologies with network externality may help to explain these phenomena. A simulation model based on heterogeneous agents is developed in order to identify the relevant factors in the diffusion of the technology.

This model is efficient because of two related reasons: it avoids the inefficiencies of a strong intellectual property regime and it implements concurrently design and testing of software modules. The hazard of open-source is that projects can fork into competing versions. Open-source communities consist of governance structures that constitutionally minimize this danger.

We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors' uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors' motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms' sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms' sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer's OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer's projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.","2022-09","2025-04-25 17:01:07","2025-04-25 17:01:07","","867","","3","33","","","","","","","","","","English","","","ABI/INFORM Global","2718384104","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Flourish+or+Perish%3F+The+Impact+of+Technological+Acquisitions+on+Contributions+to+Open-Source+Software&rft.au=Chen%2C+Wei%3BJin%2C+Fujie%3BXue%2C+Ling.&rft.aulast=Chen&rft.aufirst=Wei&rft.date=2022-09-01&rft.volume=33&rft.issue=3&rft.spage=867&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/10.1287%2Fisre.2021.1086","Open source software; Uncertainty; Open source; Software; Open-source software; Computers--Information Science And Information Theory; Corporate governance; Project management; Public domain; Technological change; Innovations; Target acquisition","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the lens of the integrative model of trust (IMoT), hypotheses regarding interactions between trust and community citizenship behaviors (CCBs – as OSSPC participating activities) are developed. Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust→CCBs and the CCBs→Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust→CCBs relationship. These findings are explained from several theoretical perspectives, which provide directions for future research and help community management to maintain sustained participation.","2022-09","2025-04-25 17:01:07","2025-04-25 17:01:07","","907-920","","5","62","","","","","","","","","","English","","","ABI/INFORM Global","2708632042","","","Place: Stillwater Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Computer+Information+Systems&rft.atitle=Sustained+Participation+in+Open+Source+Software+Project+Communities&rft.au=Shi%2C+Zhengzhong%3BSun%2C+Hua.&rft.aulast=Shi&rft.aufirst=Zhengzhong&rft.date=2022-09-01&rft.volume=62&rft.issue=5&rft.spage=907&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Computer+Information+Systems&rft.issn=08874417&rft_id=info:doi/10.1080%2F08874417.2021.1949645","Open source software; Computers; Data analysis; Open source; Participation; Hypotheses; OSS; Software; diffusion of innovation; Trust; Public domain; Software project management; Qualitative analysis; Community participation; integrative model of trust; intellectual capital creation; social learning system; stage model; sustained participation; vector autoregressive model","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

GaugeCam Remote Image Manager‐Educational 2 (GRIME2) is a mature, open‐source commercial friendly software application that automatically detects and measures water level in laboratory and field settings. The software relies on a dedicated target background for water line detection and image calibration. The system detects the change in pixel gray scale values associated with the intersection of the water level at the target surface. Fiducials on the target background are used to precisely create a pixel to real world coordinate transfer matrix and to correct for camera movement. The presented software package implements the algorithms and automates the water level measurement process, annotation of images with result overlays, creation of animations, and output of results to files that can be further analyzed in a spreadsheet or with R or Python. These GRIME2 features are illustrated using imagery from a coastal marsh field site. Tradeoffs between workflow and algorithm complexity and ease of use are discussed and future improvements are identified with the intention that this Findable, Accessible, Interoperable, and Reusable‐inspired software can be adopted, modified and improved by the user community. While image resolution, quality and other factors associated with field deployment (e.g., water surface roughness, sun glare, shadows, and bio‐fouling) will have an impact on measurement quality, previous controlled laboratory testing that did not manifest these issues showed potential for accuracy of ±3 mm (Gilmore et al., 2013, https://doi.org/10.1016/j.jhydrol.2013.05.011).","2022-08","2025-04-25 17:01:07","2025-04-25 17:01:07","","","","8","58","","","","","","","","","","English","","","ABI/INFORM Global","2707627947","","","Place: Washington Publisher: John Wiley & Sons, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Water+Resources+Research&rft.atitle=Technical+Note%3A+Open%E2%80%90Source+Software+for+Water%E2%80%90Level+Measurement+in+Images+With+a+Calibration+Target&rft.au=Chapman%2C+Kenneth+W%3BGilmore%2C+Troy+E%3BChapman%2C+Christian+D%3BBirgand%2C+Fran%C3%A7ois%3BMittelstet%2C+Aaron+R%3BHarner%2C+Mary+J%3BMehrubeoglu%2C+Mehrube%3BStranzl%2C+John+E%2C+Jr.&rft.aulast=Chapman&rft.aufirst=Kenneth&rft.date=2022-08-01&rft.volume=58&rft.issue=8&rft.spage=&rft.isbn=&rft.btitle=&rft.title=Water+Resources+Research&rft.issn=00431397&rft_id=info:doi/10.1029%2F2022WR033203","Open source software; open source software; Quality assurance; Software; Software packages; Measurement; Imagery; Software development; Algorithms; Environmental; Laboratories; Workflow; Digital image processing; Annotations; Calibration; Coastal marshes; Earth Sciences--Hydrology; hydrology; image processing; Image processing; Image quality; Image resolution; Laboratory tests; pixel to world calibration; Pixels; Shadows; stage measurement; Surface roughness; Tidal marsh; Transfer matrices; Water; Water level; Water level measurement; Water levels; waterline detection","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, this research has focused mainly on social/cultural factors, neglecting the software tools and infrastructure. To shed light on how OSS tools and infrastructure might factor into OSS barriers to entry, we conducted two studies: (1) a field study with five teams of software professionals, who worked through five use cases to analyze the tools and infrastructure used in their OSS projects; and (2) a diary study with 22 newcomers (9 women and 13 men) to investigate whether the barriers matched the ones identified by the software professionals. The field study produced a bleak result: software professionals found gender biases in 73 percent of all the newcomer barriers they identified. Further, the diary study confirmed these results: Women newcomers encountered gender biases in 63 percent of barriers they faced. Fortunately, many kinds of barriers and biases revealed in these studies could potentially be ameliorated through changes to the OSS software environments and tools.","2022","2025-04-25 17:01:07","2025-04-25 17:01:07","","241-259","","1","48","","","","","","","","","","English","","","ABI/INFORM Global","2619023727","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=How+Gender-Biased+Tools+Shape+Newcomer+Experiences+in+OSS+Projects&rft.au=Padala%2C+Hema+Susmita%3BMendez%2C+Christopher%3BFronchetti%2C+Felipe%3BSteinmacher%2C+Igor%3BSteine-Hanson%2C+Zoe%3BHilderbrand%2C+Claudia%3BHorvath%2C+Amber%3BHill%2C+Charles%3BSimpson%2C+Logan%3BBurnett%2C+Margaret%3BGerosa%2C+Marco%3BSarma%2C+Anita.&rft.aulast=Padala&rft.aufirst=Hema&rft.date=2022-01-01&rft.volume=48&rft.issue=1&rft.spage=241&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2020.2984173","Open source software; Infrastructure; newcomers; gender; Productivity; software engineering; Software; Open-source software; Tools; diversity; Documentation; Open source software (OSS); Cultural differences; Computers--Software; Software development tools; Gender; Diary studies; Field study; Human bias; Men; Problem-solving; Sexism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted a policy Delphi study involving 24 FLOSS community managers from 22 different communities. Our panel identified 16 concerns related to managing EV in FLOSS, which we ranked by prevalence. We also describe 65 practices for managing EV in FLOSS. Almost three-quarters of these practices are used by at least three community managers.

Network connections provide access to external knowledge in the community; the absorption and transfer of this new knowledge require appropriate internal knowledge and developer roles. With longitudinal data collected from 4,518 open source software development projects hosted at SourceForge, the authors show that knowledge breadth (depth) helps with the absorption of external knowledge achieved from network depth (breadth), but it inhibits the absorption of external knowledge obtained from network breadth (depth). Further, developer roles (e.g., bridge members, role diversity) can mitigate the negative consequences of suboptimal combinations and facilitate effective transfers of absorbed external knowledge across and within projects. These findings provide important theoretical and managerial implications for managing network connections, knowledge, and developer roles in open source software communities.","2020-12","2025-04-25 17:01:08","2025-04-25 17:01:08","","1651","","4","44","","","","","","","","","","English","","","ABI/INFORM Global","2472175612","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=More+Is+Not+Necessarily+Better%3A+An+Absorptive+Capacity+Perspective+on+Network+Effects+in+Open+Source+Software+Development+Communities&rft.au=Tang%2C+Tanya+%28Ya%29%3BFang%2C+Eric%28+Er%29%3BQualls%2C+William+J.&rft.aulast=Tang&rft.aufirst=Tanya&rft.date=2020-12-01&rft.volume=44&rft.issue=4&rft.spage=1651&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F13991","Open source software; Computers; Open source; Knowledge; Knowledge management; Social networks; Software development; Public domain; Network effect; Absorption; Absorptive capacity; Absorptivity; Knowledge acquisition; Knowledge community","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although many data scientists and the high-performing companies that employ them seem to have developed robust methods to employ data sciences practices to achieve competitive advantages, there have been few attempts at defining and explaining how and why data science helps firms to achieve desired outcomes. In this paper, we describe how data science, which combines computer programming, domain knowledge, and analytic skillsets to scientifically extract insights from data, can be used to help meet the growing demand of analytic needs across an organization's value chain. This is done through the illustration of an applied data science initiative to a strategic sourcing problem via the use of open-source technology. In doing so, we contribute to the growing data science literature by demonstrating the application of unique data science capabilities. Moreover, the paper provides a tutorial on how to use a specific R package along with an actual case in which that package use used.","2020-10","2025-04-25 17:01:08","2025-04-25 17:01:08","","1","","","54","","","","","","","","","","English","","","ABI/INFORM Global","2505725296","","","Place: Kidlington Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Management&rft.atitle=A+data+science+and+open+source+software+approach+to+analytics+for+strategic+sourcing%3A+SSIS&rft.au=Boehmke%2C+Brad%3BHazen%2C+Benjamin%3BBoone%2C+Christopher+A%3BRobinson%2C+Jessica+L.&rft.aulast=Boehmke&rft.aufirst=Brad&rft.date=2020-10-01&rft.volume=54&rft.issue=&rft.spage=1&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Management&rft.issn=02684012&rft_id=info:doi/10.1016%2Fj.ijinfomgt.2020.102167","Science; Open source software; Open-source software; Data science; Social Sciences: Comprehensive Works; Competitive advantage; Mathematical analysis; Computer programming; Skills; Analytics; R package; Sourcing; Strategic sourcing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-04-25 17:01:08","2025-04-25 17:01:08","","1439","","3","44","","","","","","","","","","English","","","ABI/INFORM Global","2447305472","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Takeoff+of+Open+Source+Software%3A+A+Signaling+Perspective+Based+on+Community+Activities&rft.au=Setia%2C+Pankaj%3BBayus%2C+Barry+L%3BRajagopalan%2C+Balaji.&rft.aulast=Setia&rft.aufirst=Pankaj&rft.date=2020-09-01&rft.volume=44&rft.issue=3&rft.spage=1439&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2020%2F12576","Open source software; Computers; Open source; Software; Open-source software; Signaling; Success; Technology adoption; Public domain; Statistical models; Economic value added; Information asymmetry; Product life cycle; Signal; Signal quality; Takeoff","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Faced with such challenges of increasingly complicated software design, large-scale refactoring that radically restructures the architecture of the software can be one of the solutions. In this study, we investigate and illustrate how OSS contributors accomplish large-scale refactoring in OSS development in which there is no significant corporate participation. In our observations, as the costs of coordination requirements rise, OSS contributors increase coordination capability to manage dependencies among multiple sources during the large-scale refactoring periods. Our findings suggest that OSS contributors episodically use traditional coordination mechanisms during the large-scale refactoring periods. Our study provides actionable insights into how OSS contributors make joint action that cannot be achieved by individuals working independently and use the provision of rewards in order to achieve a shared, explicit goal of large-scale refactoring.","2020","2025-04-25 17:01:08","2025-04-25 17:01:08","","150-184","","2","2","","","","","","","","","","English","","","ABI/INFORM Global","2453844031","","","Place: Geneva Publisher: Inderscience Enterprises Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Systems+and+Management&rft.atitle=Large-scale+refactoring+challenges+and+coordination+in+open+source+software+development&rft.au=Moon%2C+Eunyoung%3BHowison%2C+James.&rft.aulast=Moon&rft.aufirst=Eunyoung&rft.date=2020-01-01&rft.volume=2&rft.issue=2&rft.spage=150&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Systems+and+Management&rft.issn=17513227&rft_id=info:doi/10.1504%2FIJISAM.2020.110552","Open source software; online communities; open source; Open source; coordination; Open-source software; Coordination; Computers--Information Science And Information Theory; Software development; Public domain; Code refactoring; collaborative work; Reward; software refactoring","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, these infrequent volunteers contribute to the sustainability of FLOSS projects, and should ideally be encouraged to continue participating, even if they cannot be persuaded to contribute regularly. Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature. Also, episodic volunteers make a wide range of value-added contributions other than code, and they should neither be expected nor coerced into becoming habitual volunteers.","2020","2025-04-25 17:01:08","2025-04-25 17:01:08","","962-980","","9","46","","","","","","","","","","English","","","ABI/INFORM Global","2444610198","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Uncovering+the+Periphery%3A+A+Qualitative+Survey+of+Episodic+Volunteering+in+Free%2FLibre+and+Open+Source+Software+Communities&rft.au=Barcomb%2C+Ann%3BKaufmann%2C+Andreas%3BRiehle%2C+Dirk%3BKlaas-Jan+Stol%3BFitzgerald%2C+Brian.&rft.aulast=Barcomb&rft.aufirst=Ann&rft.date=2020-01-01&rft.volume=46&rft.issue=9&rft.spage=962&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2018.2872713","Open source software; Community; Qualitative research; free software; open source software; Software; Open-source software; Task analysis; Volunteers; Community management; Companies; Sustainable development; Public domain; Freeware; Computers--Software; Lenses; Free and open-source software; episodic volunteering; Volunteering; peripheral developer; Periphery","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We consider two types of followers: developers (those directly involved in software development) and observers (those indirectly involved in it). We conduct a series of empirical investigations by using a longitudinal dataset of OSS projects hosted in GitHub, along with a survey and qualitative data. We find that followership can affect code reuse, but the effect depends on the nature of the follower (developer or observer). Overall, our study suggests that followership is important for code reuse in OSS because it enables participants to learn, and learning promotes code reuse.","2019-12","2025-04-25 17:01:08","2025-04-25 17:01:08","","1303","","4","43","","","","","","","","","","English","","","ABI/INFORM Global","2319173778","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=Followership+in+an+Open-Source+Software+Project+and+its+Significance+in+Code+Reuse&rft.au=Jiang%2C+Qiqi%3BTan%2C+Chuan-Hoo%3BSia%2C+Choon+Ling%3BWei%2C+Kwok+Kee.&rft.aulast=Jiang&rft.aufirst=Qiqi&rft.date=2019-12-01&rft.volume=43&rft.issue=4&rft.spage=1303&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/10.25300%2FMISQ%2F2019%2F14043","Open source software; Computers; Open source; Software; Open-source software; Software development; Public domain; Software project management; Software upgrading; Source code; Code reuse; Qualitative analysis; Computer programming; Datasets; Followership","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While working on OSS projects contributors acquire project related individualistic knowledge and gain experience and skills, which often remains unshared with others and is usually lost once contributors leave a project. All software development organisations face the problem of knowledge loss as employees leave, but this situation is exasperated in OSS projects where most contributors are volunteers with largely unpredictable engagement durations. Contributor turnover is inevitable due to the transient nature of OSS project workforces causing knowledge loss, which threatens the overall sustainability of OSS projects and impacts negatively on software quality and contributor productivity. Objective: The objective of this work is to deeply and systematically investigate the phenomenon of knowledge loss due to contributor turnover in OSS projects as presented in the state-of-the-art literature and to synthesise the information presented on the topic. Furthermore, based on the learning arising from our investigation it is our intention to identify mechanisms to reduce the overall effects of knowledge loss in OSS projects. Methodology: We use the snowballing methodology to identify the relevant literature on knowledge loss due to contributor turnover in OSS projects. This robust methodology for a literature review includes research question, search strategy, inclusion, exclusion, quality criteria, and data synthesis. The search strategy, and inclusion, exclusions and quality criteria are applied as a part of snowballing procedure. Snowballing is considered an efficient and reliable way to conduct a systematic literature review, providing a robust alternative to mechanically searching individual databases for given topics. Result: Knowledge sharing in OSS projects is abundant but there is no evidence of a formal strategy or practice to manage knowledge. Due to the dynamic and diverse nature of OSS projects, knowledge management is considered a challenging task and there is a need for a proactive mechanism to share knowledge in the OSS community for knowledge to be reused in the future by the OSS project contributors. From the collection of papers found using snowballing, we consolidated various themes on knowledge loss due to contributor turnover in OSS projects and identified 11 impacts due to knowledge loss in OSS projects, and 10 mitigations to manage with knowledge loss in OSS projects. Conclusion: In this paper, we propose future research directions to investigate integration of proactive knowledge retention practices with the existing OSS practices to reduce the current knowledge loss problem. We suggest that there is insufficient attention paid to KM in general in OSS, in particular there would appear to an absence of proactive measures to reduce the potential impact of knowledge loss. We also propose the need for a KM evaluation metric in OSS projects, similar to the ones that evaluate health of online communities, which should help to inform potential consumers of the OSS of the KM status on a project, something that is not existent today.","2019-06","2025-04-25 17:01:08","2025-04-25 17:01:08","","104","","","46","","","","","","","","","","English","","","ABI/INFORM Global","2221225951","","","Place: Kidlington Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Information+Management&rft.atitle=A+systematic+examination+of+knowledge+loss+in+open+source+software+projects%3A+SSIS&rft.au=Rashid%2C+Mehvish%3BClarke%2C+Paul+M%3BO%E2%80%99Connor%2C+Rory+V.&rft.aulast=Rashid&rft.aufirst=Mehvish&rft.date=2019-06-01&rft.volume=46&rft.issue=&rft.spage=104&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Information+Management&rft.issn=02684012&rft_id=info:doi/10.1016%2Fj.ijinfomgt.2018.11.015","Open source software; Open source; Software; Open-source software; Strategy; Knowledge management; Methodology; Project management; Software development; Software quality; Systematic review; Public domain; Software Projects; Investigations; Social Sciences: Comprehensive Works; Literature reviews; Geographical distribution; Search methods; Snowballing","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study measures the firm-level productivity impact of nonpecuniary (free) OSS and finds a positive and significant value-added return for firms that have an ecosystem of complementary capabilities. There is no such impact for firms without this ecosystem of complements. Dynamic panel analysis, instrumental variables, and a variety of robustness checks are used to address measurement error concerns and to add support for a more causal interpretation of the results. For firms with an ecosystem of complements, a 1% increase in the use of nonpecuniary OSS leads to an increase in value-added productivity of between 0.002% and 0.008%. This effect is smaller for larger firms, and the results indicate that prior research underestimates the amount of IT firms use.","2019-03","2025-04-25 17:01:08","2025-04-25 17:01:08","","1191","","3","65","","","","","","","","","","English","","","ABI/INFORM Global","2198542297","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+Science&rft.atitle=Open+Source+Software+and+Firm+Productivity&rft.au=Nagle%2C+Frank.&rft.aulast=Nagle&rft.aufirst=Frank&rft.date=2019-03-01&rft.volume=65&rft.issue=3&rft.spage=1191&rft.isbn=&rft.btitle=&rft.title=Management+Science&rft.issn=00251909&rft_id=info:doi/10.1287%2Fmnsc.2017.2977","Open source software; Productivity; Open source; Software; Open-source software; Measurement; Companies; Financial performance; Robustness; Public domain; Business And Economics--Labor And Industrial Relations; Economic value added; Instrumental variables estimation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Then, the detection rate and remaining faults of previous release are considered in the modeling and analysis of reliability of the current release. The optimal version-update time is computed using multi-attribute utility theory for these software systems, considering the two main utility factors, namely, rapid release strategy and level of reliability.

Often this takes the form of company employees devoting their time to contribute code to the efforts of projects in these communities. Ideology has traditionally served to motivate, coordinate, and guide volunteer contributions to OSS communities. As employees represent an increasing proportion of the participants in OSS communities, the role of OSS ideology in guiding their commitment and code contributions is unknown. In this research, we argue that OSS ideology misfit has important implications for companies and the OSS communities to which their employees contribute, since their engagement in such communities is not necessarily voluntary. We conceptualize two different types of misfit: OSS ideology under-fit, whereby an employee embraces an OSS ideology more than their coworkers or OSS community do, and OSS ideology over-fit, whereby an employee perceives that their coworkers or OSS community embrace the OSS ideology more strongly than the employee does. To develop a set of hypotheses about the implications of these two types of misfit for employee commitment to the company and commitment to the OSS community, we draw on self-determination theory. We test the hypotheses in a field study of 186 employees who participate in an OSS community. We find that OSS ideology under-fit impacts the company and the community in the same way: it decreases employee commitment to the company and commitment to the OSS community. In contrast, we find that OSS ideology over-fit increases commitment to the company but decreases commitment to the OSS community. Finally, we find that employees’ commitment to their company reinforces the impact of their commitment to the OSS community in driving ongoing code contributions. This provides a holistic view of OSS ideology and its impacts among an increasingly pervasive yet understudied type of participant in OSS research. It provides insights for companies that are considering assigning their employees to work in OSS communities as well as for OSS communities that are partnering with these companies.","2018-12","2025-04-25 17:01:09","2025-04-25 17:01:09","","1069","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2136026232","","","Place: Minneapolis Publisher: University of Minnesota, MIS Research Center","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=MIS+Quarterly&rft.atitle=The+Impact+of+Ideology+Misfit+on+Open+Source+Software+Communities+and+Companies&rft.au=Daniel%2C+Sherae+L%3BMaruping%2C+Likoebe+M%3BCataldo%2C+Marcelo%3BHerbsleb%2C+Jin.&rft.aulast=Daniel&rft.aufirst=Sherae&rft.date=2018-12-01&rft.volume=42&rft.issue=4&rft.spage=1069&rft.isbn=&rft.btitle=&rft.title=MIS+Quarterly&rft.issn=02767783&rft_id=info:doi/","Open source software; Computers; Open source; Hypotheses; Software; Open-source software; Commitment; Impact analysis; Public domain; Employees; Software services; Community participation; Ideology; Self-determination","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A series of hypotheses about how distributed innovation (independent variables) influences knowledge sharing (mediating variable) and then affects the performance of OSS projects (dependent variable) are tested and approved. On the one side, we argue that developers will actively affect knowledge sharing in terms of participative motivation, social network and organisational culture. On the other hand, users may also affect the knowledge sharing when considering innovation willingness and capacity. It is interesting to find that social network is the most important factor in Chinese cases.

In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience.

In this research, we advance on such studies through an integrated FLOSS evaluation-selection model with a risk-based decision-making approach. Our model was built upon the other two literatures, and it was structured as a multi-attribute decision-making (MADM) model which contains 12 variables grouped in four risk categories: financial, organisational, end user, and technical ones. We illustrated its utilisation in the domain of information technology service management (ITSM) FLOSS tools. Hence, our model contributes to the FLOSS literature with the inclusion of the risk management approach and to the FLOSS evaluation-selection praxis with the provision of an innovative and essential risk-based model.","2016","2025-04-25 17:01:10","2025-04-25 17:01:10","","326","","4","16","","","","","","","","","","English","","","ABI/INFORM Global","1861798477","","","Place: Geneva Publisher: Inderscience Enterprises Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=International+Journal+of+Technology+Policy+and+Management&rft.atitle=An+MADM+risk-based+evaluation-selection+model+of+free-libre+open+source+software+tools&rft.au=Mora%2C+Manuel%3BG%C3%B3mez%2C+Jorge+Marx%3BO%27Connor%2C+Rory+V%3BGelman%2C+Ovsei.&rft.aulast=Mora&rft.aufirst=Manuel&rft.date=2016-10-01&rft.volume=16&rft.issue=4&rft.spage=326&rft.isbn=&rft.btitle=&rft.title=International+Journal+of+Technology+Policy+and+Management&rft.issn=14684322&rft_id=info:doi/","Open source software; Decision making; Information technology; Studies; Open source; Software; Risk management; Programming tool; Technology: Comprehensive Works; Decision making models; IT service management; Multiple criteria decision making","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These decisions formed a coherent IP strategy in support of OSS. We find that IBM's actions stimulated new OSS product introductions by entrepreneurial firms and that their impact is increasing in the cumulativeness of innovation in the market and the extent to which patent ownership in the market is concentrated.","2016-09","2025-04-25 17:01:10","2025-04-25 17:01:10","","2668","","9","62","","","","","","","","","","English","","","ABI/INFORM Global","2677663077","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Management+Science&rft.atitle=Opening+Up+Intellectual+Property+Strategy%3A+Implications+for+Open+Source+Software+Entry+by+Start-up+Firms&rft.au=Wen%2C+Wen%3BCeccagnoli%2C+Marco%3BForman%2C+Chris.&rft.aulast=Wen&rft.aufirst=Wen&rft.date=2016-09-01&rft.volume=62&rft.issue=9&rft.spage=2668&rft.isbn=&rft.btitle=&rft.title=Management+Science&rft.issn=00251909&rft_id=info:doi/10.1287%2Fmnsc.2015.2247","Open source software; Innovation; Open source; Open-source software; Ownership; Patents; Companies; Intellectual property; Strategic planning; Innovations; Business And Economics--Labor And Industrial Relations; Startups; Patent; Company; Patent law","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It has been suggested that such small-scale and home-grown solutions (e.g. mobile phone apps), usually championed by social enterprises (SEs), are more likely to introduce pro-poor change than infrastructure heavy ICr initiatives designed by state and other international actors. In the Indian context, FOSS-based social innovations (Sis) introduced by SEs are helping poor communities tackle previously thought-to-be unresolvable socio-economic problems. An interesting question, therefore, would be: in what ways is the SE model and approach uniquely equipped to develop FOSS-based Sis that deliver pro-poor change? The empirical component of the research attempts to shed light on this question by uncovering the nuts and bolts of the development methodology deployed by an SE during the coding and launch of an FOSS-based SI. Findings highlight the significant role of the founder's social vision; the challenges of accurately capturing and translating to software developers the nature and nuance of social problems; and, the incumbent issues in putting together a methodology that creates active user engagement throughout the software development process, overcoming difficult barriers such as language and culture.","2016-07","2025-04-25 17:01:10","2025-04-25 17:01:10","","28","","","52/53","","","","","","","","","","English","","","ABI/INFORM Global","1798370797","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Technovation&rft.atitle=Social+innovation+with+open+source+software%3A+User+engagement+and+development+challenges+in+India&rft.au=Bhatt%2C+Punita%3BAhmad%2C+Ali+J%3BRoomi%2C+Muhammad+Azam.&rft.aulast=Bhatt&rft.aufirst=Punita&rft.date=2016-06-01&rft.volume=52%2F53&rft.issue=&rft.spage=28&rft.isbn=&rft.btitle=&rft.title=Technovation&rft.issn=01664972&rft_id=info:doi/","Open source software; Innovation; India; Studies; User behavior; Open source; 9130:Experiment/theoretical treatment; 9179:Asia & the Pacific; 8302:Software & computer services industry; Innovations; Technology: Comprehensive Works; 1220:Social trends & culture; 7100:Market research; Software services; Developing country; Social innovation; Customer engagement; Social change; Social enterprise","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The increased participation is an observable phenomenon; many researchers and practitioners assume that the practice of community sharing does not improve the bottom line, but rather believe the practice is altruistic in nature. Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, ""Why do for-profit corporations participate in the development of open source software?"" was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory. In this article, we examine interview responses and field study data from corporate members of open source communities to determine how they justify devoting time and effort to community engagement. Our study makes a contribution to open source software literature by revealing that numerous rational and emotional reasons exist for corporate participation in open source software development.","2016","2025-04-25 17:01:10","2025-04-25 17:01:10","","323-343","","4","26","","","","","","","","","","English","","","ABI/INFORM Global","1830348270","","","Place: Mahwah Publisher: Lawrence Erlbaum Associates, Inc.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.atitle=Game+theory+and+open+source+contribution%3A+Rationale+behind+corporate+participation+in+open+source+software+development&rft.au=Kendall%2C+Julie+E.%3BKendall%2C+Kenneth+E.%3BGermonprez%2C+Matt.&rft.aulast=Kendall&rft.aufirst=Julie&rft.date=2016-01-01&rft.volume=26&rft.issue=4&rft.spage=323&rft.isbn=&rft.btitle=&rft.title=Journal+of+Organizational+Computing+and+Electronic+Commerce&rft.issn=10919392&rft_id=info:doi/10.1080%2F10919392.2016.1228360","Open source software; Open source; open source software; Participation; Software; Open-source software; Game theory; open source communities; Software development; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; 9130:Experimental/theoretical; 2600:Management science/operations research; Business And Economics--Computer Applications; Cooperative game; Coopetition; Drama Theory; game theory","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Adequate support in license use is vital in order to avoid such violations and address how diverse licenses should be handled. In the current work we investigate software licensing giving a critical and comparative overview of existing assistive approaches and tools. These approaches are centered on three main categories: license information identification from source code and binaries, software metadata stored in code repositories, and license modeling and associated reasoning actions.

We show that, contrary to standard predictions, additional contribution to the public good by the government or a new market entrant can lead to higher investments of all incumbent firms, that is, a crowding-in effect. This result occurs if the investment cost function is superadditive. We find that government contribution leads to larger crowding-in effects than subsidizing market entry if the price elasticity of demand with respect to the private good is large relative to the one with respect to the public good.

However, the incomplete understanding of the phenomenon has continued to prompt researchers to investigate factors that could increase the use and popularity of open source software (OSS). While a key antecedent for OSS use highlighted in the previous literature is the software quality, we propose that effective online user support is also necessary to increase its popularity. As an understudied area, this paper seeks to understand the role of online user support networks in facilitating OSS use. Based on the network embeddedness theory, it suggests that properties of the user support network i.e., variation in structural and junctional embeddedness, measured as the in-degree and betweenness centralizations respectively, would affect OSS popularity in terms of the number of active users and downloads of the software. Testing on a sample of 176 OSS projects from Sourceforge.net, we showed that a negative quadratic relationship exists between the variation in structural embeddedness of the OSS user support network and the software popularity. Further, as hypothesized, the variation in junctional embeddedness was found to positively impact the OSS popularity. Theoretical and practical implications of the study are discussed.","2014-08","2025-04-25 17:01:11","2025-04-25 17:01:11","","142","","","64","","","","","","","","","","English","","","ABI/INFORM Global","1558315974","","","Place: Amsterdam Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Decision+Support+Systems&rft.atitle=Uncovering+the+relationship+between+OSS+user+support+networks+and+OSS+popularity&rft.au=Sutanto%2C+Juliana%3BKankanhalli%2C+Atreyi%3BTan%2C+Bernard+CY.&rft.aulast=Sutanto&rft.aufirst=Juliana&rft.date=2014-08-01&rft.volume=64&rft.issue=&rft.spage=142&rft.isbn=&rft.btitle=&rft.title=Decision+Support+Systems&rft.issn=01679236&rft_id=info:doi/","Open source software; Studies; Open-source software; Social networks; Software quality; 5240:Software & systems; 9130:Experiment/theoretical treatment; Computers--Automation; User services; Mathematical models; Proprietary","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In doing so, it offers new insights into the association between open innovation and diversification. We rely on arguments inspired by the literature and evidence collected through interviews with OSS SMEs' top managers to investigate factors that favor or hinder within-industry diversification. First, in line with the mainstream diversification literature, we focus attention on the role of firm size. Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products. Furthermore, we provide preliminary evidence that the practice of authorizing firm programmers to contribute autonomously to OSS projects of their own choice during working hours may be positively associated to within-industry diversification only if OSS SMEs possess adequate internal technological resources.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory. According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another. The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-04-25 17:01:11","2025-04-25 17:01:11","","127-143","","2","39","","","","","","","","","","English","","","ABI/INFORM Global","1929783648","","","Place: Ahmedabad Publisher: Sage Publications, New Delhi India","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Vikalpa&rft.atitle=The+Emergence+of+an+Organizational+Field%3A+The+Case+of+Open+Source+Software&rft.au=Ojha%2C+Abhoy+K%3BRao%2C+Ravi+Anand.&rft.aulast=Ojha&rft.aufirst=Abhoy&rft.date=2014-04-01&rft.volume=39&rft.issue=2&rft.spage=127&rft.isbn=&rft.btitle=&rft.title=Vikalpa&rft.issn=02560909&rft_id=info:doi/10.1177%2F0256090920140211","Open source software; Business And Economics--Management; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Adopting a sociolinguistic perspective, we conceptualize group maintenance behavior as interpersonal communication tactics -- specifically, social presence and politeness tactics -- that help maintain relationships among group members. Developer email messages were collected from two FLOSS projects with different development statuses, and their content was analyzed to identify frequently used group maintenance tactics. We then compared the group maintenance tactics used in the two projects, finding differences that reflect changes in the project work practices. Our work theoretically contributes to FLOSS research and has practical implications for FLOSS practitioners.

Both of these aspects can be modified, depending on the evaluation made of a series of characteristics (or dimensions) inherent to the model. (ii) The free dissemination of the source code of the application not only allows the transfer of knowledge, but also creates virtual communities which, through collaborative work and the exchange of experiences, can achieve a better fit of the technology to the task at hand. This model has been introduced in several departments at the University of Granada (Spain), and evaluated in terms of the results obtained at both individual and group levels. This evaluation was conducted by means of in-depth interviews with departmental managers.

In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving. We discuss the applicability of relational events models in organizational research.

In doing so, we consider the content of potential information flows within the network and argue that the impact of network structure on technology adoption can be better understood by separately examining its impact from two groups of alters-current and potential adopters. We contend that increased network centrality and closure among current adopters contribute positively to adoption, whereas the same among potential adopters has exactly the opposite impact. Accordingly, we propose a dynamic view where the fraction of current adopters in the network positively moderates the impact of network centrality and closure. We empirically test the theory by analyzing the adoption of software version control technology by open source software projects. Our results strongly support the theory.

In recent years, firms motivated by revenues from software services markets have become the primary contributors to open-source development. In this paper we study the role of services in open source software development and explore the choice between open source and proprietary software. Specifically, our economic model jointly analyzes the investment and pricing decisions of the originators of software and of subsequent open-source contributors. We find that if a contributor is efficient in software development, the originator should adopt an open-source strategy, allowing the contributor to offer higher total quality and capture the higher end of the market while the originator focuses on providing software services to lower end consumers. Conversely, if the contributor is not efficient in development, the originator should adopt a proprietary software development strategy, gaining revenue from software sales and squeezing the contributor out of the services market. In certain cases an increase in originator development efficiency can result in increased contributor profits. Finally, we find that, somewhat counterintuitively, an increase in contributor development efficiency can reduce overall social welfare.

The current findings support the argument that OSS-adopting organizations can be clearly distinguished from their non-adopting counterparts in terms of their availability of internal OSS human capital, accessibility to external OSS human capital, organizational size, IT department size, and criticality of IT operation.

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated 'copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the 'new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11","2025-04-25 17:01:12","2025-04-25 17:01:12","","597-625","","4","42","","","","","","","","","","English","","","ABI/INFORM Global","2089824849","","","Place: Abingdon Publisher: Taylor & Francis LLC","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Economy+and+Society&rft.atitle=Free+software+production+as+critical+social+practice&rft.au=Barron%2C+Anne.&rft.aulast=Barron&rft.aufirst=Anne&rft.date=2013-11-01&rft.volume=42&rft.issue=4&rft.spage=597&rft.isbn=&rft.btitle=&rft.title=Economy+and+Society&rft.issn=03085147&rft_id=info:doi/10.1080%2F03085147.2013.791510","Open source software; Law; open source; Resistance; Business And Economics; free software; Software; reputational capital; Free software; Property; Capitalism; Economic theory; Free and open-source software; Profitability; Profits; Free; Accumulation; copyleft; Economic sectors; immaterial labour; new spirit of capitalism; Private property; Renewal; Social relations","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the US. This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? The authors interviewed the CIO, or equivalent position, at 17 not-for-profit and public hospitals across the US. Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk.","2013-12","2025-04-25 17:01:12","2025-04-25 17:01:12","","361","","4","38","","","","","","","","","","English","","","ABI/INFORM Global","1435635391","","","Place: Frederick Publisher: Lippincott Williams & Wilkins Ovid Technologies","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Health+Care+Management+Review&rft.atitle=The+use+and+role+of+open+source+software+applications+in+public+and+not-for-profit+hospitals+in+the+United+States&rft.au=Vest%2C+Joshua+R%3BStephens%2C+James+H.&rft.aulast=Vest&rft.aufirst=Joshua&rft.date=2013-10-01&rft.volume=38&rft.issue=4&rft.spage=361&rft.isbn=&rft.btitle=&rft.title=Health+Care+Management+Review&rft.issn=03616274&rft_id=info:doi/","Open source software; Studies; Open source; Open-source software; Technology adoption; Hospitals; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; United States--US; 9190:United States; Cost control; Nonprofit organizations; Public; Nonprofit organization; 62211:General Medical and Surgical Hospitals; 8320:Health care industry; Health Facilities And Administration; Hospital; Medical technology","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Following a cohort of OSS programmers over a six-year period, they empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, their findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18% increase in wages. Moreover, they find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management.","2013-09","2025-04-25 17:01:12","2025-04-25 17:01:12","","520-538,879,881","","3","24","","","","","","","","","","English","","","ABI/INFORM Global","1445136928","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=All+Are+Not+Equal%3A+An+Examination+of+the+Economic+Returns+to+Different+Forms+of+Participation+in+Open+Source+Software+Communities&rft.au=Hann%2C+Il-Horn%3BRoberts%2C+Jeffrey+A%3BSlaughter%2C+Sandra+A.&rft.aulast=Hann&rft.aufirst=Il-Horn&rft.date=2013-09-01&rft.volume=24&rft.issue=3&rft.spage=520&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/","Open source software; Studies; Productivity; Open source; Participation; Hypotheses; Software; Open-source software; Computers--Information Science And Information Theory; Internet; Project management; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; United States--US; 9190:United States; 1130:Economic theory; Employment; Labor economics; Labor market; Workers; Signal; Absenteeism; Employers; Performance; Wage; Wages & salaries","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Their results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its interproject social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. Finally, they find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license.","2013-09","2025-04-25 17:01:12","2025-04-25 17:01:12","","539-560,880-881","","3","24","","","","","","","","","","English","","","ABI/INFORM Global","1445136834","","","Place: Linthicum Publisher: Institute for Operations Research and the Management Sciences","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+Systems+Research&rft.atitle=Networks%2C+Social+Influence%2C+and+the+Choice+Among+Competing+Innovations%3A+Insights+from+Open+Source+Software+Licenses&rft.au=Singh%2C+Param+Vir%3BPhelps%2C+Corey.&rft.aulast=Singh&rft.aufirst=Param&rft.date=2013-09-01&rft.volume=24&rft.issue=3&rft.spage=539&rft.isbn=&rft.btitle=&rft.title=Information+Systems+Research&rft.issn=10477047&rft_id=info:doi/","Open source software; Studies; Open source; Software license; Open-source software; Licenses; License; Social influence; Computers--Information Science And Information Theory; Project management; Social networks; Network; Software development; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; Technological change; Innovations; United States--US; 9190:United States; Licensing; Employees; 5250:Telecommunications systems & Internet communications; Employers","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We approach these adoption challenges as a problem of gaining support for organizational innovation. Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are -- on average -- more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect. Suggestions for PCSS firms are presented and implications for innovation literature are discussed.

Interest in Spatial Databases is, however, more widespread - especially with the increasing understanding of the relevance of geospatial techniques to fields as diverse as anthropology and architecture. This article describes the development and evaluation of a self-paced hands-on course on Databases and Spatial Databases for CEGE students, presented to students to complement and enhance in-class teaching. The article focuses on both pedagogical elements of self-paced learning and the suitability of Free and Open Source Software and Open Data (PostgreSQL/PostGIS, Quantum GIS, Open Street Map) for the Spatial Databases curriculum. The resulting material was evaluated by a cohort of 25 students in 2010, and their feedback (very positive) and the overall results provide an interesting insight into suitable methods to employ when teaching technical subjects to a cohort having differing background skill levels.

Although researchers have studied some predictors of OSS project performance, there is a lack of empirical work that studies the impact of project capabilities on the performance of OSS projects. Therefore, this paper studies project capabilities as potential predictors of OSS project performance. The data, gathered from 607 OSS projects over time (in two snap-shots), were consistent with Dynamic Capability Theory (DCT). In other words, the results showed that in order to achieve higher project performance, OSS projects need to have strong capabilities in terms of proactive and efficient defect-removal as well as proactive and efficient functionality-enhancement. The implications of these results for the OSS research community are discussed, followed by recommendations for OSS practitioners.

However, while there is no shortage on research on individuals' motivation for contributing to open source, few have investigated the commercial companies' motivations for doing the same. A case study was conducted at three different companies from the IT service industry, to investigate three possible drivers: sale of complimentary services, innovation and opensourcing (outsourcing). We offer three conclusions. First, we identified three main drivers for contributing to open source, which are (a) selling complimentary services, (b) building greater innovative capability and (c) cost reduction through opensourcing to an external community. Second, while previous research has documented that the most important driver is selling complimentary services, we found that this picture is too simple. Our evidence points to a broader set of motivations, in the sense that all our cases exhibit combinations of the three drivers. Finally, our findings suggest that there might be a shift in how commercial companies view open source software. The companies interviewed have all expressed a moral obligation to contribute to open source.

The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.","2012-04","2025-04-25 17:01:13","2025-04-25 17:01:13","","920","","4","85","","","","","","","","","","English","","","ABI/INFORM Global","925777279","","","Place: New York Publisher: Elsevier Sequoia S.A.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=The+Journal+of+Systems+and+Software&rft.atitle=Free+and+Open+Source+Software+versus+Internet+content+filtering+and+censorship%3A+A+case+study&rft.au=Shirazi%2C+Farid.&rft.aulast=Shirazi&rft.aufirst=Farid&rft.date=2012-04-01&rft.volume=85&rft.issue=4&rft.spage=920&rft.isbn=&rft.btitle=&rft.title=The+Journal+of+Systems+and+Software&rft.issn=01641212&rft_id=info:doi/","Open source software; Studies; Censorship; Open source; Software packages; Internet; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Computers--Software; Free and open-source software; Systems design; 9178:Middle East; Filtering software; Iran","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nonetheless, scholars have never tested this assertion. This paper takes a first step toward filling this gap. First, based on the high-tech entrepreneurship literature and the OSS research stream, we illustrate why collaborations with the OSS community should exert a positive effect on entrepreneurial ventures' innovation performance. Then, we provide a rigorous quantitative analysis of the innovation impact of these collaborations. Our econometric estimates indicate that entrepreneurial ventures collaborating with the OSS community exhibit superior innovation performance compared with their noncollaborating peers.

Compared with the prevailing proprietary approaches, open-source software products are developed by co-opting external developers and prospective users. Although a core group of developers might still play a key role in the initial design and development, a notable aspect of the open-source software paradigm is the role of peripheral developers in the enhancement and popularization of the product. Peripheral developers are not formal members of the core development team. They voluntarily contribute their time and creative talent in improving the quality of the product or in popularizing the product through word-of-mouth advocacy. As volunteers, they are not subject to the traditional hierarchical controls, nor are they contractually obligated. Peripheral developers represent a novel and unique aspect of open-source software development, and there is a greater interest in tapping their potential. However, there has been limited evidence about how and when their participation has beneficial impacts. We examine how peripheral developers contribute to product quality and diffusion by utilizing longitudinal data on 147 open-source software products. Hierarchical linear modeling analysis indicates that peripheral developers make significant contributions to product quality and diffusion, especially on projects that are in the more mature stages of product development.

These attributes make OSS an enticing technological choice for a company. Unfortunately, because most enterprises view technology as a proprietary differentiating element of their operation, little is known about the extent of OSS adoption in industry and the key drivers behind adoption decisions. In this article we examine factors and behaviors associated with the adoption of OSS and provide empirical findings through data gathered from the US Fortune-1000 companies. The data come from each company's web browsing and serving activities, gathered by sifting through more than 278 million web server log records and analyzing the results of thousands of network probes. We show that the adoption of OSS in large US companies is significant and is increasing over time through a low-churn transition, advancing from applications to platforms. Its adoption is a pragmatic decision influenced by network effects. It is likelier in larger organizations and those with many less productive employees, and is associated with IT and knowledge-intensive work and operating efficiencies.

Following a case study approach, the Apache Web server's market potential is estimated, forecasted and examined in terms of the socio-economic factors determining its diffusion, across different economic environments in developed versus developing countries. Market saturation is explored under the prism of three theoretical perspectives: the institutional, the endogenous and the exogenous growth theories. Findings suggest that Apache market saturation levels depend on both endogenous and exogenous to a country factors and that institutional quality plays an important role to the market potential. Implications for theory and public policy are discussed.

With dual licensing, a firm releases the same software product under both a traditional proprietary license and an open source one. We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of ""going open source"" and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

However, there have been conflicting reports on the extent to which this is true of the embedded software systems sector -- a large sector in Europe. This paper reports on attitudes towards Open Source software within that sector. Our results show a high level of acceptance of Open Source products with large, well established communities, and not only at the level of the operating system. Control over the software is seen as fundamentally important. Other key perceptions with Open Source are an easing of long-term maintenance problems and ready availability of support. The classical strengths of Open Source, namely mass inspection, ease of conducting trials, longevity and source code access for debugging, were at the forefront of thinking. However, there was an acknowledgement that more guidelines are needed for assessing Open Source software and incorporating it into products.

Drawing on research in information systems and sociology, this study develops and evaluates an integrated model for the acceptance of OSS. In addition to the traditional technology adoption variables the findings stress the importance of social identification as a key driver of OSS adoption. The proposed model provides a useful decision support tool for assessing and proactively designing interventions targeted at successful OSS adoption and diffusion.

Such side work may be a good thing for the employing firms, too, if they get some strategic value from the open-source software and if the productivity of the programmers on these projects improves through learning-by-doing effects. However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses. However, if attractive alternate employment opportunities are available, they change their strategy and may offer bonuses for both projects simultaneously.

This paper seeks to identify how organizations adopt OSS, classify the literature according to these ways of adopting OSS, and with a focus on software development evaluate the research on adoption of OSS in organizations. Based on the systematic literature review method, the authors reviewed publications from 24 journals and seven conference and workshop proceedings, published between 1998 and 2008. From a population of 24,289 papers, the authors identified 112 papers that provide empirical evidence on how organizations actually adopt OSS. The authors show that adopting OSS involves more than simply using OSS products. The authors moreover provide a classification framework consisting of six distinctly different ways in which organizations adopt OSS. The authors find that existing research on OSS adoption does not sufficiently describe the context of the organizations studied, and it fails to benefit fully from related research fields.","2010-11","2025-04-25 17:01:14","2025-04-25 17:01:14","","1133","","11","52","","","","","","","","","","English","","","ABI/INFORM Global","751213257","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Adoption+of+open+source+software+in+software-intensive+organizations+-+A+systematic+literature+review&rft.au=Hauge%2C+%C3%98yvind%3BAyala%2C+Claudia%3BConradi%2C+Reidar.&rft.aulast=Hauge&rft.aufirst=%C3%98yvind&rft.date=2010-11-01&rft.volume=52&rft.issue=11&rft.spage=1133&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Open source; Open-source software; Technology adoption; Software development; Systematic review; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Computers--Data Base Management; Literature reviews","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.

These organizations are voluntary in nature and rely on contributions from members to achieve their objectives. Examples include the Linux operating system and other FOSS projects, political movements, churches and religious groups, Habitat for Humanity, and similar charitable organizations. In this paper, we consider a world containing agents with heterogeneous abilities who may voluntarily choose to make effort contributions to one or more different public projects. Agents are motivated by a desire to be seen as significant contributors to important and valuable projects, the warm glow from the act of contributing, and a desire to directly enjoy the benefits of projects when complete. We find that contributions from others can be either strategic complements or substitutes. We show that Nash equilibria exist and study how agents' abilities and project quality affect the equilibrium levels of contributions.

These platforms are usually centered in a specific brand/product and their members are linked by a shared admiration to that brand. This paper analyzes one of the most powerful online collaborative platforms, the free software (FS) case, which involves a lot of virtual communities developed around products such as Linux or Android, the new Google's mobile operating system. Our purpose is to determine some of the main antecedents and consequences of the consumer involvement in this type of communities. Results have shown that satisfaction with a virtual community may increase the level of consumer participation in that community. At the same time, a greater identification with the virtual community may increase indirectly the consumer participation thanks to the enhancement of his/her satisfaction with the community. We have also found positive and significant effects of consumer identification and participation on the level of community promotion. Finally, positive and significant effects of consumer participation and satisfaction with the community on loyalty to the FS were also found. These findings allow us to conclude some interesting managerial implications.

These efforts aim to identify common elements in the development process between multiple open source software projects. In this paper, the authors propose that the Design and Engineering Methodology for Organizations (DEMO) may provide an interesting alternative to develop OSSD process models. DEMO exhibits two unique features within the context of OSSD process modeling. First, DEMO analyzes processes at the ontological level and provides high-level process descriptions, instead of focusing on the implementation level. Second, DEMO studies the communication patterns between human actors, instead of the sequences in which activities are performed. The authors investigate the feasibility of using DEMO to construct OSSD process models by means of a case study. Their results showed that their DEMO models exhibited a high level of abstraction, thereby reducing the complexity of the OSSD process models. The authors have shown that the DEMO methodology can be successfully used to model OSSD processes and to obtain abstract and high-quality OSSD process models.","2010-06","2025-04-25 17:01:14","2025-04-25 17:01:14","","656","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","196420145","","","Place: Amsterdam Publisher: Elsevier Science Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Information+and+Software+Technology&rft.atitle=Using+the+DEMO+methodology+for+modeling+open+source+software+development+processes&rft.au=Huysmans%2C+Philip%3BVen%2C+Kris%3BVerelst%2C+Jan.&rft.aulast=Huysmans&rft.aufirst=Philip&rft.date=2010-06-01&rft.volume=52&rft.issue=6&rft.spage=656&rft.isbn=&rft.btitle=&rft.title=Information+and+Software+Technology&rft.issn=09505849&rft_id=info:doi/","Open source software; Studies; Software; Models; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Software Projects; Computers--Data Base Management; Ontology; Demo; Process modeling","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding the factors that affect the involvement and contributions of participants in OSS projects is of significance to facilitate project success. This paper investigates the effects of motivation on participant performance in OSS projects, drawing upon self-determination theory to examine how task effort (i. e., effort intensity and goal commitment) mediates the relationships between a spectrum of motivations and individual performance. The research model is supported by survey data from 204 participants in OSS projects. The theoretical contributions and managerial implications are discussed.

A recent literature has focused on the question of the business models explaining how and why firms may draw benefits from such involvement and their connected activities. They can be considered as the building blocks of a new modus operandi of an industry, built on an alternative approach to intellectual property management. Its prospects will depend on both the firms' willingness to rally and its ability to compete with the traditional proprietary approach. As a matter of fact, firms' involvement in FLOSS, while growing, remains very contrasted, depending on the nature of the products and the characteristics of the markets. This paper asks why for-profit firms contribute to FLOSS development and why some firms contribute more than others. The common explanation is that FLOSS is often a complement to proprietary software (or hardware or services) that the for-profit firm sells at a positive price. We present an alternative explanation based on the users' skill level. When users are skilled, opening the software is likely to result in a better product because the user base will contribute improvements (find bugs, write fixes and produce new features). We introduce the concept of the dominant user's skill and set up a theoretical model to better understand how it may condition the nature and outcome of the competition between a FLOSS firm and a proprietary firm. We discuss these results in the light of stylized facts drawn from recent trends in the software industry.

Nearly all open source software is free software; the two terms describe almost the same category of software. But they stand for views based on fundamentally different values. Open source is a development methodology; free software is a social movement. As the advocates of open source draw new users into the community, free software activists must work even more to bring the issue of freedom to those new users attention.","2009-06","2025-04-25 17:01:15","2025-04-25 17:01:15","","31","","6","52","","","","","","","","","","English","","","ABI/INFORM Global","237063687","","","Place: New York Publisher: Association for Computing Machinery","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=unknown&rft.jtitle=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.atitle=Why+%26quot%3BOpen+Source%26quot%3B+Misses+the+Point+of+Free+Software&rft.au=Stallman%2C+Richard.&rft.aulast=Stallman&rft.aufirst=Richard&rft.date=2009-06-01&rft.volume=52&rft.issue=6&rft.spage=31&rft.isbn=&rft.btitle=&rft.title=Association+for+Computing+Machinery.+Communications+of+the+ACM&rft.issn=00010782&rft_id=info:doi/","Open source software; Community; Open source; Software; Free software; Freedom; 5240:Software & systems; Freeware; United States--US; 9190:United States; Open; Computers--Data Communications And Data Transmission Systems; Definitions; Differences","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.

Specifically, our research focused on learning effects of OSS projects and the factors that affect the learning process. The number and percentage of resolved bugs and bug resolution time of 118 SourceForge.net OSS projects were used to measure the learning effects. Projects were characterized by project type, number and experience of developers, number of bugs, and bug resolution time. Our results provided evidence of virtual organizational learning in OSS development projects and support for several factors as determinants of performance. Team size was a significant predictor, with mid-sized project teams functioning best. Teams of three to seven developers exhibited the highest efficiency over time and teams of eight to 15 produced the lowest mean time for bug resolution. Increasing the percentage of bugs assigned to specific developers or boosting developer participation in other OSS projects also improved performance. Furthermore, project type introduced variability in project team performance.

Respondents to an extensive web-survey's (FLOSS-US 2003) questions about their reasons for beginning to work FLOSS are classified according to their distinct ""motivational profiles"" by hierarchical cluster analysis. Over half of them also are matched to projects of known membership sizes, revealing that although some members from each of the clusters are present in the small, medium and large ranges of the distribution of project sizes, the mixing fractions for the large and the very small project ranges are statistically different. Among developers who changed projects, there is a discernable flow from the bottom toward the very small towards to large projects, some of which is motivated by individuals seeking to improve their programming skills. It is found that the profile of early motivation, along with other individual attributes, significantly affects individual developers' selections of projects from different regions of the size range.

These same institutions have also resulted in conflicts regarding community purposes and the quality and delivery of the community's output. We examine the institutional redesign undertaken to address these problems and derive implications for F/LOS communities and companies.

An important - but sometimes neglected - group of OSS users are Independent Software Vendors (ISVs). lSVs often develop their applications on top of OSS platform software. Frequently, this requires making several extensions and modifications to these OSS components. We identify a number of challenges that ISVs face in handling these extensions and modifications. Next, we describe several strategies ISVs can follow in maintaining these modifications. Finally, we suggest an opportunity for a closer collaboration between OSS projects and ISVs which could be mutually beneficial.

Following a case study methodology, we examined developer interaction data from three active and successful FLOSS projects using qualitative research methods, specifically inductive content analysis, to identify the task-assignment mechanisms used by the participants. We found that 'self-assignment' was the most common mechanism across three FLOSS projects. This mechanism is consistent with expectations for distributed and largely volunteer teams. We conclude by discussing whether these emergent practices can be usefully transferred to mainstream practice and indicating directions for future research.

We adapt a dynamic private-provision-of-public-goods model to reflect key aspects of the OSS phenomenon, such as play value or homo ludens payoff, user-programmers' and gift culture benefits.

This paper develops a framework of the OSS community ideology (including specific norms, beliefs, and values) and a theoretical model to show how adherence to components of the ideology impacts effectiveness in the OSS team. The model is based on the idea that the tenets of the OSS ideology motivate behaviors that enhance cognitive trust and communication quality and encourage identification with the project team, which enhances effective trust. Trust and communication in turn impact OSS team effectiveness. The research considers to kinds of effectiveness in OSS teams: the attraction and retention of developer input and the generation of project outputs. Hypotheses regarding antecedents to each are developed. Hypotheses are tested using survey and objective data on OSS projects. Results support the main thesis that OSS team ideology impacts OSS team effectiveness and reveal that different components impact effectiveness in different ways. Of particular interest is the finding that adherence to some ideological components was beneficial to the effectiveness of the team in terms of attracting and retaining input, but detrimental to the output of the team. Theoretical and practical implications are discussed.

However, the academic research on knowledge management in OSS is sparse. In this paper, a knowledge management system for OSS is proposed in the framework of systems theory. Knowledge, knowledge management, organization and information technology are the four main interactive elements in the knowledge management system. The paper proposes that each subsystem of the OSS is to be equipped with knowledge management capacity, and the knowledge management of the OSS is to be realized through its subsystems.

Open source software (OSS) has challenged much of the traditional reasoning by suggesting that individuals behave altruistically and contribute to a public good, despite the opportunity to free-ride. The lion's share of the existing literature on OSS examines communities, that is, those individuals whom are already part of the OSS community. In contrast, this paper starts from users with the requisite skill to use and develop OSS. This group of skilled individuals could potentially invest into the development of OSS knowledge, but they may or may not do so in actuality. This paper, therefore, explores three issues, which have not been extensively explored in the literature, namely, (1) how frequently a group of skilled people use OSS, (2) reasons for differences among users and non-users in terms of use and attitudes, and (3) how frequently, and why, some users contribute to OSS projects (and thereby become developers). In doing so, we consider the opportunity costs of use and development of OSS, which has been largely neglected in the literature. We find that the individuals have a rather pragmatic attitude to firms and that many are active in both firms and OSS community, which raises many questions for future research about the role and influence of firms on the development and diffusion of OSS.

A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm-community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.

In the early parts of the paper it is argued that, although GNU/LINUX can generate substantial savings when used instead of the proprietary alternative in numerous institutional settings, the most telling opportunities for developing countries arise when this system is combined with other ways of reducing computing costs. Policy, therefore, should not only consist of substituting GNU/LINUX for proprietary software in running the latest and most expensive hardware, but also of lowering these latter costs themselves. Later sections focus on the link between the choice of software and path-dependency. It is suggested that the problem of proprietary lock-in in developing countries has been greatly accentuated by piracy of Microsoft operating systems and that the result is a stagnation of the technological capabilities in software that these countries need so badly.","2003","2025-04-25 17:01:17","2025-04-25 17:01:17","","25-33","","1","29","","","","","","","","","","English","","","ABI/INFORM Global","224652541","","","Place: Amsterdam Publisher: Bowker-Saur Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Journal+of+Information+Science&rft.atitle=Free+software+and+the+digital+divide%3A+Opportunities+and+constraints+for+developing+countries&rft.au=James%2C+Jeffrey.&rft.aulast=James&rft.aufirst=Jeffrey&rft.date=2003-01-01&rft.volume=29&rft.issue=1&rft.spage=25&rft.isbn=&rft.btitle=&rft.title=Journal+of+Information+Science&rft.issn=01655515&rft_id=info:doi/10.1177%2F016555103762202041","Studies; Library And Information Sciences; Linux; Operating systems; Free software; 5240:Software & systems; Freeware; 9130:Experimental/theoretical; 9180:International; International; Cost control; Developing countries--LDCs; Developing country; Internet access; Digital divide; Digital; LDCs","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals’ early career stages profoundly impact their long-term career success. However, newcomers’ early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers’ dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers’ contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers’ early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers’ technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers’ early careers and hence shed light on future research in this direction.","2023","2025-04-25 17:01:51","2025-04-25 17:01:51","","529-548","","2","49","","","","","","","","","","English","","","ABI/INFORM Global","2776777604","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=Off+to+a+Good+Start%3A+Dynamic+Contribution+Patterns+and+Technical+Success+in+an+OSS+Newcomer%26rsquo%3Bs+Early+Career&rft.au=Yang%2C+Yue%3BWang%2C+Yi%3BRedmiles%2C+David.&rft.aulast=Yang&rft.aufirst=Yue&rft.date=2023-01-01&rft.volume=49&rft.issue=2&rft.spage=529&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2022.3156071","Careers; open source; Task analysis; Ecosystems; Success; Documentation; Engineering profession; Codes; Correlation; Newcomer; Focusing; Statistical analysis; Computers--Software; Empirical analysis; Dynamic contribution pattern; early career; newcomer; technical success","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Several vulnerability scanners to detect known-vulnerable dependencies appeared in the last decade, however, there exists no case study investigating the impact of development practices, e.g., forking, patching, re-bundling, on their performance. This paper studies (i) types of modifications that may affect vulnerable open-source dependencies and (ii) their impact on the performance of vulnerability scanners. Through an empirical study on 7,024 Java projects developed at SAP , we identified four types of modifications: re-compilation, re-bundling, metadata-removal and re-packaging. In particular, we found that more than 87 percent (56 percent, resp.) of the vulnerable Java classes considered occur in Maven Central in re-bundled (re-packaged, resp.) form. We assessed the impact of these modifications on the performance of the open-source vulnerability scanners OWASP Dependency-Check (OWASP) and Eclipse Steady, GitHub Security Alerts, and three commercial scanners. The results show that none of the scanners is able to handle all the types of modifications identified.

Although the quality of developers’ contributions should be the only factor influencing the evaluation of the contributions to OSS projects, recent studies have shown that diversity issues are correlated with the acceptance or rejection of developers’ contributions. Objective: This paper assists this emerging state-of-the-art body on diversity research with the first empirical study that analyzes how developers’ perceptible race and ethnicity relates to the evaluation of the contributions in OSS. We also want to create awareness of the racial and ethnic diversity in OSS projects. Methodology: We performed a large-scale quantitative study of OSS projects in GitHub. We extracted the developers’ perceptible race and ethnicity from their names in GitHub using the Name-Prism tool and applied regression modeling of contributions (i.e, pull requests) data from GHTorrent and GitHub. Results: We observed that (1) among the developers whose perceptible race and ethnicity was captured by the tool, only 16.56 percent were perceptible as Non-White developers; (2) contributions from perceptible White developers have about 6–10 percent higher odds of being accepted when compared to contributions from perceptible Non-White developers; and (3) submitters with perceptible non-white races and ethnicities are more likely to get their pull requests accepted when the integrator is estimated to be from their same race and ethnicity rather than when the integrator is estimated to be White. Conclusion: Our initial analysis shows a low number of Non-White developers participating in OSS. Furthermore, the results from our regression analysis lead us to believe that there may exist differences between the evaluation of the contributions from different perceptible races and ethnicities. Thus, our findings reinforce the need for further studies on racial and ethnic diversity in software engineering to foster healthier OSS communities.","2022","2025-04-25 17:01:52","2025-04-25 17:01:52","","2955-2968","","8","48","","","","","","","","","","English","","","ABI/INFORM Global","2703102371","","","Place: New York Publisher: IEEE Computer Society","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=IEEE+Transactions+on+Software+Engineering&rft.atitle=On+the+Relationship+Between+the+Developer%26rsquo%3Bs+Perceptible+Race+and+Ethnicity+and+the+Evaluation+of+Contributions+in+OSS&rft.au=Nadri%2C+Reza%3BRodriguez-Perez%2C+Gema%3BNagappan%2C+Meiyappan.&rft.aulast=Nadri&rft.aufirst=Reza&rft.date=2022-01-01&rft.volume=48&rft.issue=8&rft.spage=2955&rft.isbn=&rft.btitle=&rft.title=IEEE+Transactions+on+Software+Engineering&rft.issn=00985589&rft_id=info:doi/10.1109%2FTSE.2021.3073773","Open source software; GitHub; Ethnicity; software development; open source software; Race; Software engineering; Open-source software; Tools; Psychology; Regression analysis; Multiculturalism; Gender issues; Software development management; Diversity; Cultural differences; Perceptible race and ethnicity diversity; Developer; Computers--Software; Empirical analysis; Ethnic group; Integrators; Multiculturalism & pluralism","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Economics often pictures this phenomenon as a case of signalling: individuals engage in the volunteer programming of open-source software (OSS) as a labour-market signal resulting in a wage premium. Yet, this explanation could so far not be empirically tested. This article fills this gap by estimating an upper-bound composite wage premium of voluntary OSS contributions and by separating the potential signalling effect of OSS engagement from other effects. Although some 70% of OSS contributors believe that OSS involvement benefits their careers, we find no actual labour-market premium for OSS engagement. The presence of other motives, such as fun of play or altruism, renders OSS contributions too noisy to function as a signal.","2017-03","2025-04-25 17:01:52","2025-04-25 17:01:52","","1379-1394","","14","49","","","","","","","","","","English","","","ABI/INFORM Global","1881460983","","","Place: London Publisher: Taylor & Francis Ltd.","","","https://libkey.io/libraries/72/openurl?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQuest&rft_val_fmt=journal&rft.genre=article&rft.jtitle=Applied+Economics&rft.atitle=Is+there+a+wage+premium+for+volunteer+OSS+engagement%3F+-+signalling%2C+learning+and+noise&rft.au=Bitzer%2C+J%C3%BCrgen%3BGeishecker%2C+Ingo%3BSchr%C3%B6der%2C+Philipp+J.+H..&rft.aulast=Bitzer&rft.aufirst=J%C3%BCrgen&rft.date=2017-03-01&rft.volume=49&rft.issue=14&rft.spage=1379&rft.isbn=&rft.btitle=&rft.title=Applied+Economics&rft.issn=00036846&rft_id=info:doi/10.1080%2F00036846.2016.1218427","Open source software; peer production; Business And Economics; Open-source software; Noise; Engagement; open-source software; Public domain; Volunteering; D01; J24; J31; Signalling; voluntary work; wage formation","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With it, they aim to empower and encourage development teams across organizations to perform small-scale, routine usability testing. A usability lab is, in essence, an observation platform for learning from the interaction between a participant and an application. Their experience shows that setting up an observation platform with enough quality for usability testing can be done with relative ease, without licensing fees or special platform requirements.

While the benefits resulting from network externality have been examined in the related literature, the effect of free offer on the diffusion of new software has not been formally analyzed. We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters. Our methodology is shown to be applicable for both fixed and dynamic pricing strategies.

Specifically, in the self-augmented contrastive learning module, we construct a retrieval-based in-context prompt scheme by retrieving similar but different category data from the original samples, guiding the LLM to generate more discriminative augmented data. Then, by designing group-level contrastive loss to enhance the model`s discriminative ability. In the external-augmented contrastive learning module, we utilize web knowledge retrieval to expand the sample space and leverage LLM to generate more diverse data, and introduce sample-level contrastive loss for unlabeled data to improve the model`s generalization.

This evolution, while heralding new opportunities, introduces emerging challenges, particularly in terms of biases and unfairness, which may threaten the information ecosystem. In this paper, we present a comprehensive survey of existing works on emerging and pressing bias and unfairness issues in IR systems when the integration of LLMs. We first unify bias and unfairness issues as distribution mismatch problems, providing a groundwork for categorizing various mitigation strategies through distribution alignment. Subsequently, we systematically delve into the specific bias and unfairness issues arising from three critical stages of LLMs integration into IR systems: data collection, model development, and result evaluation. In doing so, we meticulously review and analyze recent literature, focusing on the definitions, characteristics, and corresponding mitigation strategies associated with these issues. Finally, we identify and highlight some open problems and challenges for future work, aiming to inspire researchers and stakeholders in the IR field and beyond to better understand and mitigate bias and unfairness issues of IR in this LLM era.

Next, we created a codebook and inputted the sample text and codebook into an LLM. We asked the LLM to determine if the codes were present in a sample text provided and requested evidence to support the coding. The sample texts were inputted 160 times to record changes between iterations of the LLM response. Each iteration was analogous to a new coder deductively analyzing the text with the codebook information. In our results, we present the outputs for these recursive analyses, along with a comparison of the LLM coding to evaluations made by human coders using traditional coding methods. We argue that LLM analysis can aid qualitative researchers by deductively coding transcripts, providing a systematic and reliable platform for code identification, and offering a means of avoiding analysis misalignment.

Systematic selection of relevant papers through conventional means like keyword-based filtering techniques can sometimes be inadequate, plagued by semantic ambiguities and inconsistent terminology, which can lead to sub-optimal outcomes. To mitigate the required extensive manual filtering, we explore and evaluate the potential of using Large Language Models (LLMs) to enhance the efficiency, speed, and precision of literature review filtering, reducing the amount of manual screening required. By using models as classification agents acting on a structured database only, we prevent common problems inherent in LLMs, such as hallucinations. We evaluate the real-world performance of such a setup during the construction of a recent literature survey paper with initially more than 8.3k potentially relevant articles under consideration and compare this with human performance on the same dataset. Our findings indicate that employing advanced LLMs like GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Flash, or Llama3 with simple prompting can significantly reduce the time required for literature filtering - from usually weeks of manual research to only a few minutes. Simultaneously, we crucially show that false negatives can indeed be controlled through a consensus scheme, achieving recalls >98.8% at or even beyond the typical human error threshold, thereby also providing for more accurate and relevant articles selected. Our research not only demonstrates a substantial improvement in the methodology of literature reviews but also sets the stage for further integration and extensive future applications of responsible AI in academic research practices.","2024-07-15","2025-04-29 01:13:39","2025-04-29 01:13:39","2025-04-29 01:13:39","","","","","","","Cutting Through the Clutter","","","","","arXiv","","","","","","","arXiv.org","","arXiv:2407.10652 [cs] version: 1","","/Users/mgone/Zotero/storage/NPXIP4GA/Joos et al. - 2024 - Cutting Through the Clutter The Potential of LLMs.pdf; /Users/mgone/Zotero/storage/53L2N539/2407.html","","","Computer Science - Human-Computer Interaction; Computer Science - Digital Libraries; Computer Science - Machine Learning","","","","","","","","","","","","","","","","","","","arXiv:2407.10652","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Scientific OSS, built on the open-source model, has been especially valuable in supporting scientific discovery and the corresponding research communities. However, ensuring the sustainability of the community by attracting newcomers and retaining existing contributors is recognized as a major challenge for the long-term success of OSS. While previous research has studied sustainability in OSS broadly, the active involvement of scientists—many of whom lack formal training in professional software engineering—and the presence of highly interdependent projects that create a multi-project ecosystem with interconnected communities may introduce unique challenges that differ from those in commonly studied OSS contexts. In this study, we explore sustainability challenges and opportunities within the scientific OSS community, aiming to understand how these aspects align with or differ from those in previously researched OSS communities. Through a survey-based replication study in the Astropy Project—a widelyused OSS ecosystem in astronomy—we gathered insights from disengaged contributors regarding their motivations, reasons for disengagement, and suggestions for improving community sustainability. Our findings reveal key motivations driving contributions to scientific OSS, identify barriers to sustained engagement, and propose strategies to address these challenges, highlighting areas for future research.","","2025-04-29 14:10:02","2025-04-29 14:10:03","","","","","","","","","","","","","","","en","","","","","Zotero","","","","/Users/mgone/Zotero/storage/4G2FYV68/Sun et al. - Advancing Sustainable Communities in Scientific OS.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is difficult to evaluate the usefulness of these descriptions, and how effectively they improve access to meaningful information, because we have little understanding of the semantic content they convey, and how different readers receive this content. In response, we introduce a conceptual model for the semantic content conveyed by natural language descriptions of visualizations. Developed through a grounded theory analysis of 2,147 sentences, our model spans four levels of semantic content: enumerating visualization construction properties (e.g., marks and encodings); reporting statistical concepts and relations (e.g., extrema and correlations); identifying perceptual and cognitive phenomena (e.g., complex trends and patterns); and elucidating domain-specific insights (e.g., social and political context). To demonstrate how our model can be applied to evaluate the effectiveness of visualization descriptions, we conduct a mixed-methods evaluation with 30 blind and 90 sighted readers, and find that these reader groups differ significantly on which semantic content they rank as most useful. Together, our model and findings suggest that access to meaningful information is strongly reader-specific, and that research in automatic visualization captioning should orient toward descriptions that more richly communicate overall trends and statistics, sensitive to reader preferences. Our work further opens a space of research on natural language as a data interface coequal with visualization.","2022-01","2025-05-02 20:24:00","2025-05-02 20:33:11","2025-05-02 20:24:00","1073-1083","","1","28","","","Accessible Visualization via Natural Language Descriptions","","","","","","","","","","","","IEEE Xplore","","","","/Users/mgone/Zotero/storage/EKZ6YDVK/9555469.html; /Users/mgone/Zotero/storage/8XR9RF5L/Lundgard and Satyanarayan - 2022 - Accessible Visualization via Natural Language Desc.pdf","","","theory; Media; disability; Data visualization; Guidelines; accessibility; Visualization; Semantics; blind; alt text; caption; description; Graphics; model; natural language; Natural languages; semantic","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The most dangerous reported violations are spatial safety violations, where objects are accessed outside of their bounds. A wide variety of spatial safety sanitizers promise easy usage, broad security guarantees, and a low execution time overhead. However, only few of them are actually used. Instead of proposing yet another sanitizer, we dig deep into Low-Fat Pointers and SoftBound, two approaches to generate fast-to-execute safe programs with strong safety guarantees, and identify pain points in their usage. We found that seemingly small simplifying assumptions or limitations of the approaches often lead to spurious error reports. On top of analyzing usability issues, we set up a framework that abstracts common tasks of memory safety instrumentations, such as finding locations for checks and eliminating redundant checks. This abstraction allows us to draw a fair comparison between approaches when it comes to execution time and the number of safe accesses. We use this framework to give novel insights into how many accesses are provably safe, and where to attribute execution time overhead. Our findings help future research on memory safety instrumentations by identifying issues that current approaches face in their practical application. We make our LLVM-based instrumentation framework available to reduce the effort required to implement new instrumentations and to ease comparisons to Low-Fat Pointers and SoftBound.","2025-03-01","2025-05-02 20:50:30","2025-05-02 20:50:30","2025-05-02","390–404","","","","","","Memory Safety Instrumentations in Practice","CGO '25","","","","Association for Computing Machinery","New York, NY, USA","","","","","","ACM Digital Library","","","","/Users/mgone/Zotero/storage/H8PCEZ9T/Jung et al. - 2025 - Memory Safety Instrumentations in Practice Usabil.pdf","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Four diamictons interbedded with glaciomarine and glaciofluvial sediments are exposed in a large gravel pit situated above the post-glacial marine limit. The interpretation of these sediments has implications for the history of both the inland ice and the Norwegian Channel Ice Stream. During a Middle Weichselian interstadial, a large glaciofluvial delta prograded into a shallow marine environment along the coast of Jaeren. A minor glacial advance deposited a gravelly journal of Quaternary Science diamicton, and a glaciomarine diamicton was deposited during a following marine transgression. This subsequently was reworked by grounded ice, forming a well-defined boulder pavement. The boulder pavement is followed by glaciomarine clay with a lower, laminated part and an upper part of sandy clay. The laminated clay probably was deposited under sea-ice, whereas more open glaciomarine conditions prevailed during deposition of the upper part. The clay is intersected by clastic dykes protruding from the overlying, late Weichselian till. Preconsolidation values from the marine clay suggest an ice thickness of at least 500 m during the last glacial phase. The large variations in sea-level probably are a combined effect of eustasy and glacio-isostatic changes caused by an inland ice sheet and an ice stream in the Norwegian Channel.

Within wide limits topography and soil type, texture, and fertility seemed to be of minor importance, although milkweed appeared to grow best on well drained lighter soils of average to high fertility and was never found on poorly drained or highly acid soils. Milkweed appeared to find its most favorable environment on recently abandoned row-crop land and on recently cut-over stump land in situations where a sod of quackgrass or bluegrass had not been established. In Emmet County, probably the most densely infested county in the U.

Fiber characterization and potential market identification are critical to its development. The most promising commercial use for milkweed floss is as a loose fill for jackets and comforters. The purpose of this research was to evaluate milkweed floss as an insulative fill material and to compare its performance to other insulators. Seven identical jackets were constructed using different fill materials matched on a per unit weight basis. The insulation (clo) values for the jackets were measured using a standing, heated manikin in an environmental chamber. Thickness (loft), compression, resiliency, and hand were also measured. Several performance characteristics were evaluated before and after cleaning. The results show that milkweed floss blended with down has insulative properties similar to down. Down is superior to milkweed floss in loftiness and compressibility, which influence product performance, but the properties of milkweed floss can be enhanced by blending with down.","1991-04","2025-05-05 17:01:19","2025-05-05 17:01:19","","203-210","","4","61","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

During pyrolysis, acetic acid, formic acid and methanol are formed in addition to CO2 and H2O. The data also show that pyrolytic decomposition of the three chemical constituents of milkweed occur without any apparent synergistic interaction. The combustion of milkweed produced CO2 and H2O, as expected, but the removal of the waxy coating from the fibers results in an increased susceptibility to combustion.

Preliminary method for the A50 road link (Eindhoven-Oss, The Netherlands)","NA","","0925-8574","10.1016/S0925-8574(96)00024-9","NA","After years of efforts to avoid or reduce the impact of infrastructure projects on nature, the principle of ecological compensation has been incorporated in Dutch governmental policy. Ecological compensation aims to recover those ecological functions and natural values that still remain affected after maximum effort has been made to reduce the impact of the intervention (mitigation). The accepted aim of current policy is thus no-net-loss of area and quality by means of mitigative and compensatory measures. As part sf the planning process for construction of a stretch of road in The Netherlands, viz,, the A50 road link in the province of North Brabant, a Nature Compensation Plan (NCP) was required to be drawn up. This work has recently been completed by the Regional Directorate of Public Works and Water Management, the initiator of the intervention. The NCP, initially presented as a Draft Plan, was drawn up by the Regional Directorate using a preliminary method designed by the Centre of Environmental Science of Leiden University for deriving compensatory measures. After an opportunity for public comment, the Draft Plan was revised to form a Final NCP. This article describes, firstly, the preliminary method for deriving ecological compensatory measures. The method starts by quantifying the effects of habitat loss, habitat disturbance (by changes in noise emissions, in the water table and in outdoor recreational patterns), barrier action and fauna casualties. Following mitigation of impacts on nature, compensation for non-mitigable effects focuses successively on area size, derived from the impact on breeding birds, and on area quality, derived from the habitat requirements of the vegetation and fauna groups affected by the road. Guidelines for identifying appropriate locations for compensation are also formulated. Secondly, the compensation method is applied to calculate the mitigative and compensatory measures for the A50 trajectory between Eindhoven and Oss. Thirdly, two comparisons are made: the Draft NCP is compared with the results of the preliminary method, and the Draft and the Final NCP are compared with one another in order to identify the role of the interest groups that played a major role in commenting on the Draft Plan. Finally, realization of the compensatory measures and development of the preliminary method itself are discussed. On the basis of the experience with the A50 case study, a more robust compensation method for road projects is to be developed.","1996-12","2025-05-05 17:01:19","2025-05-05 17:01:19","","327-349","","4","7","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS Publisher: ELSEVIER SCIENCE BV","","","","mitigation; quality; barrier action; habitat disturbance; habitat loss; road infrastructure; \n fauna casualties; no-net-loss of area","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The method starts by randomly fragmenting a BAG, YAC or PAC to 8-12 kb pieces and subcloning those into lambda phage. Insert-ends of these clones are sequenced and overlapped to create a partial map. Complete sequencing is then done on a minimal tiling path of selected subclones, recursively focusing on those at the edges of contigs to facilitate mergers of clones across the entire target. To reduce manual labor, PCR processes have been adapted to prepare sequencing templates throughout the entire operation. The streamlined process can thus lend itself to further automation. The OSS approach is suitable for large-scale genomic sequencing, providing considerable flexibility in the choice of subclones or regions for more or less intensive sequencing. For example, subclones containing contaminating host cell DNA or cloning vector can be recognized and ignored with minimal sequencing effort; regions overlapping a neighboring clone already sequenced need not be redone; and segments containing tandem repeats or long repetitive sequences can be spotted early on and targeted for additional attention.","1997","2025-05-05 17:01:20","2025-05-05 17:01:20","","25-34","","NA","2985","","","","PROCEEDINGS OF THE SOCIETY OF PHOTO-OPTICAL INSTRUMENTATION ENGINEERS\n (SPIE)","","","","","","NA","","","","","","","Backup Publisher: Int Biomed Opt Soc; Soc Photo Opt Instrumentat Engineers; Amer Soc Laser\n Med & Surg Inc ISBN: 0-8194-2396-3 Place: NA Publisher: NA","","","","NA","","Cohn, G.

Anorganic bovine bone (Bio-Oss) has been reported to be osteoconductive, and no inflammatory responses have been observed with the use of this biomaterial. One of the main questions pertaining to Bio-Oss concerns its biodegradation and substitution by host bone. Some investigators have observed rapid replacement by host bone, while other researchers observed slow resorptive activity or no resorption at all. The aim of the present study was to conduct a long-term histologic analysis of retrieved specimens in humans where Bio-Oss was used in sinus augmentation procedures. Specimens were retrieved from 20 patients after varying peri ods from 6 months to 4 years and were processed to obtain thin ground sections. Bio-Oss particles were surrounded for the most part by mature, compact bone. In some Haversian canals it was possible to observe small capillaries, mesenchymal cells, and osteoblasts in conjunction with new bone. No gaps were present at the interface between the Bio-Oss particles and newly formed bone, in specimens retrieved after 18 months and 4 years, it was also possible to observe the presence of osteoclasts in the process of resorbing the Bio-Oss particles and neighboring newly formed bone. Bio-Oss appears to be highly biocompatible and osteoconductive, is slowly resorbed in humans, and can be used with success as a bone substitute in maxillary sinus augmentation procedures.","1999-12","2025-05-05 17:01:20","2025-05-05 17:01:20","","835-840","","6","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC","","","","anorganic bovine bone; biomaterials; sinus augmentation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.–Richard Stallman and Simson Garfinkel (1992)This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]","1999","2025-05-05 17:01:20","2025-05-05 17:01:20","","94–112","","3","12","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Sociology; Computers; Open source; Individualism; Computer science; Open-source software; Electronic commerce; Patents; Intellectual property; Algorithms; 5240:Software & systems; Public domain; 5250:Telecommunications systems & Internet communications; Patent; 5230:Hardware; Digital Revolution; Patent infringement; 45411:Electronic Shopping; Mail-Order Houses","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper tries to account for these problems, namely: (1) the Lewis base, or electron donor component, is much greater than the Lewis acid or electron-acceptor component because of the reference values for water chosen in the original GvOC theory. A direct comparison of the acidic component with the basic one of the same materials has no meaning. A new reference scale for water which is able to overcome this problem is suggested. For the calculation of acid-base components, a best-fit approach is proposed which does not require any starting information about the liquids or polymers and can yield estimates of the acid-base parameters for both the liquids and the polymers involved; (2) the strong dependence of the value of the acid-base components on the three liquids employed is due to ill-conditioning of the related set of equations, an intrinsic and purely mathematical feature which cannot be completely cured by any realistic improvement in experimental accuracy. To reduce or eliminate the effect, one only needs a proper set of liquids, representative of all kinds of different solvents: (3) the negative coefficients appear as a simple consequence of measurement uncertainty, combined with the possible ill-conditioning of the equation set. We cannot exclude, however, that in some cases they could have a different origin.","2000","2025-05-05 17:01:21","2025-05-05 17:01:21","","235-272","","2","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This involved a total of 15 sinus floor elevation procedures being carried out on 11 patients (average age of 49.6 years) according to the technique described by Tatum (1986). The subantral sinus cavity was augmented using bovine apatite combined with venous blood. After an average healing phase of 6.8 months, trephine burrs were used to take 22 bone biopsies from the augmented sinus region. Then 38 Branemark(R) implants were inserted in both the osteotomies resulting from bone sampling and in regular sites in the augmented posterior maxilla. Histomorphometric analysis of ground sections from the bone biopsies prepared according to the standard method of Donath & Breuner (1982) produced an average percentage of newly-formed bone of 14.7% (+/-5.0%) and a proportion of residual xenogenic bone substitute material of 29.7% (+/-7.8%). Some 29.1% (+/-8.1%) of the surface of the Bio-Oss(R) granulate was in direct contact with newly-formed bone. Histologically, newly-developed bone became evident, partly invaginating the particles of apatite and forming bridges in the form of trabeculae between the individual Bio-Oss(R) particles. Despite the absence of osteoclastic activity, the inward growth of bone indicates slow resorption of the xenogenic bone graft material. When the implants were uncovered, after an average healing phase of 6 months, 4 of the 38 implants had become loose. Of these 4 implants, 1 had to be subsequently explanted, while the others remained as “sleeping implants” and were not included in the implants superstructure. Thus, the resulting clinical survival rate, prior to prosthetic loading, was 89.5%.","2000-06","2025-05-05 17:01:22","2025-05-05 17:01:22","","217-229","","3","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","sinus augmentation; bone grafting; bone substitute; endosseous implant; \n xenograft","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The interrater reliability (.85 to .92) and temporal stability (.79 to .94) of the RCF-OSS are acceptable. RCF-OSS correlated moderately with RCF accuracy memory and organization, however it seems to be measuring an independent aspect of performance, possibly strategy. Moderate Linear relationships were observed with executive function and memory measures. Considerable age-related variation in strategy formation was observed with significant maturity occurring between the ages of 7 years and 11 years. Surprisingly, older children used fragmented strategies more than the younger age groups.

These cylinders offer light weight, corrosion resistance, dimensional stability, and the ability to store more air than equivalent metal tanks. The design methodology currently used for composite tanks, however, cannot yet guarantee their safe operation. Accordingly, the U.S. Department of Transportation (DOT) is unable to issue full certification of filament-wound tanks. Rather, some types of composite pressure tanks currently are manufactured under DOT Exemption, TC Regulation 3FCM. The composite tank industry would benefit by improving the safety of operating these tanks. The interest in developing composite pressure tanks is here and the manufacturing technology is mature. What is needed, however, is a means of insuring that composite tanks are as safe to operate as metal tanks. This will facilitate DOT certification and appeal to consumers. This paper discusses a fiber optic sensor system embedded into the composite shell wall as a structural health monitor. Using a simple, low-cost optical fiber sensor and a modified commercial connector, “smart” tanks can be monitored continuously for structural integrity. The opportunity to provide such continuity in structural health monitoring should have a significant positive impact on obtaining DOT certifications and extending product useful life. This paper presents the results of a design program to develop a new filament-wound composite cylinder containing a fiber-optic sensor system (FOSS). The purpose of FOSS is to monitor the structural integrity of the composite material each time the tank is refilled with pressurized gas. Continuous monitoring for material degradation will be an important factor that determines tank recertification intervals and useful tank life. One of the greatest challenges of this design program has been to develop an optical connector that allows external instrumentation to be “plugged into” the composite wall to read optical signals that correlate with structural health. “While embedding fiber sensors has become routine, ingress to and egress from the embedded units remain a major stumbling block” (Spillman, 1995). A simple modification to a commercial connector is proposed for this application. The design and manufacture of the prototype FOSS cylinder shown in Figure 1 are described in this paper. Connector performance and the overall performance of a prototype Type III tank consisting of an aluminum liner, an E-glass/epoxy filament-wound overwrap, and an embedded FOSS are discussed. Results of a pressure test to assess FOSS performance are presented.","2001","2025-05-05 17:01:23","2025-05-05 17:01:23","","191-196","","NA","NA","","","","International Offshore and Polar Engineering Conference Proceedings","","","","","","NA","","","","","","","Backup Publisher: Int Soc Offshore & Polar Engineers; Canadian Assoc Petr Producers; Amer\n Soc Civil Engineers, Engn Mech Div; Korea Comm Ocean Resources & Engn;\n Canadian Soc Civil Engineers, Engn Mech Div; Chinese Soc Ocean\n Engineers; Chinese Soc Naval Architects & Marine Engineers; Chinese Soc\n Theoret & Appl Mech; Russian Acad Sci; Singapore Struct Steel Soc;\n Norwegian Petr Soc; Inst Engineers Australia; Kansai Soc Naval\n Architects; IRO; Tech Res Ctr Finland; Soc Mat Sci; Offshore Engn Soc;\n Ukraine Soc Mech Engineers; IFREMER; Scott Polar Res Inst; Inst\n Engineers Indones; Brazilian Soc Naval Architects & Marine Engineers;\n Korean Soc Civil Engineers ISBN: 1-880653-55-9 Place: NA Publisher: NA","","","","NA","","Langen, I.; Yao, T.; Koo, J.; Knapp, R.

The aim of this study was to compare the gliding capacities of different flosses with major differences in structure and experimental behavior in vivo. Methods: In a clinical, single-blind, crossover study of 27 subjects, the forces necessary for passing all 14 proximal contacts between the first premolars were measured using 2 polytetrafluoroethylene (PTFE)-based flosses, 2 nylon-based flosses, and 1 nylon-based tape. The flosses were fixed in a special holder with strain gauges, which allowed registration of the maximum forces at insertion into and removal from the interdental area. Results: In most contacts, the PTFE flosses needed less force compared to the nylon flosses. The range between the flosses was higher in the mandible compared to the maxilla and increased from the mesially located contacts to the more distally located contacts. The nylon tape required higher forces at insertion for all maxillary contacts. All other flosses proved to be equivalent at these contacts. Conclusions: PTFE flosses are superior to nylon flosses in terms of passing stronger proximal contacts in both directions. Due to gliding differences between different types of floss, the selection of a floss has the potential of compensating intra- and interindividual variation in contact strengths.","2001-05","2025-05-05 17:01:23","2025-05-05 17:01:23","","672-678","","5","72","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We have found that several OSS systems appear not to obey some of ""Lehman's laws"" of software evolution [5, 7], and that Linux in particular is continuing to grow at a geometric rate. Currently, we are working on a detailed study of the evolution of one of the subsystems of the Linux kernel: the SCSI drivers subsystem. We have found that cloning, which is usually considered to be an indicator of lazy development and poor process, is quite common and is even considered to be a useful practice.Second, we are developing a tool called Beagle to aid software maintainers in understanding how large systems have changed over time.

-"VMSNEP6V","journalArticle","2001","McGowan, D.","Legal implications of open-source software","NA","","0276-9948","NA","NA","The proliferation of computer technology and the advent of the Internet have created many new relationships and problems that raise questions about traditional legal and economic principles. The development of “open-source” or “free” software is an example of this phenomenon. Unlike the traditional producers of computer software - Microsoft for example - open-source software is often developed by computer programmers from all over the world, each submitting contributions to the code, and distributed without charge or for a minimal fee. Open-source software is generally passed from programmer to programmer, with the understanding that improvements may be made, but that the improvements must be distributed freely, without any attempt to “privatize” the program. The existence of such relationships among programmers raise several interesting questions. First, how do large-scale open-source projects come into being? One open-source project, the GNU/Linux operating system, even threatens the market share of Microsoft's operating systems - a feat that calls traditional economic theories on the operation of the firm into question. A more important question is whether the open-source model is sustainable and generalizable. Ultimately, one wonders what role the law will play in the open-source community - a community that seems to operate in the absence of traditional legal principles. In this article, which was introduced at the University of Illinois College of Law Symposium on Intellectual Property Challenges in the Next Century, Professor McGowan addresses these questions. Using the GNU/Linux operating system as a case study, he probes the organization of the open-source community and the philosophies of its leading members in order to understand how traditional firm models, intellectual property, and contract law might apply. Professor McCowan concludes by reviewing recent attempts by courts to impose traditional principles in computer software transaction disputes. Ultimately, it appears that the open-source community cannot be neatly categorized. Although many traditional firm theories - such as the formation of a hierarchy - and legal principles - such as copyright - do apply to the open-source model, these theories and principles are employed in creative ways not previously envisioned.","2001","2025-05-05 17:01:23","2025-05-05 17:01:23","","241-304","","1","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: COLLEGE OF LAW-76 LAW BLDG 504 E PENNSYLVANIA AVE, CHAMPAIGN, IL 61820\n USA Publisher: UNIV ILLINOIS","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, controversy exists regarding the need to cover the lateral osteotomy site with a membrane. Also, the healing period before loading remains undefined when machined-surface implants are placed. Twenty-nine patients showing reduced bone volume in the posterior maxilla had 61 Branemark System implants placed in 30 sinuses augmented with a lateral osteotomy approach. Sinuses grafted with Bio-Oss and covered with a collagen membrane Bio-Gide (M+) received 29 implants, while grafted but uncovered sites (M-) received 32 implants. An immediate procedure was followed to place 41 implants and a staged procedure was used for 20 implants, Abutment connection was made in 2 distinct postoperative periods: 6 to 9 months and over 9 months. The patients were followed for an average of 22.4 months. The survival rate of the implants was dependent on the postoperative healing time and membrane presence. In case of the immediate procedure and in M- sites, when residual bone height was less than 5 mm, more failures occurred when the loading was done at 6 to 9 months than after 9 months. No failures occurred in the M- series when a staged approach was followed. The overall survival rate was 78.1% for the M- sites and 93.1% for the M+ sites. No failures occurred (0/35) in the control implants placed in adjacent native bone. Implant survival rate was related to the quality of the reconstructed cortical plate and to implant length. The concomitant use of a collagen barrier to cover the osteotomy site, when machined-surface implants were used in sinus grafting, seemed to improve the quality of the graft healing and survival rate of the implants loaded between 6 and 9 months after placement.","2001-10","2025-05-05 17:01:24","2025-05-05 17:01:24","","713-721","","5","16","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 4350 CHANDLER DRIVE, HANOVER PARK, IL 60133 USA Publisher: QUINTESSENCE PUBLISHING CO INC","","","","bone grafting; endosseous dental implants; maxillary sinus; membranes","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.","2001-10","2025-05-05 17:01:24","2025-05-05 17:01:24","","277-304","","4","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","control; McDonaldization; networked organization; rationalization; virtual organization; \n trust","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Whereas there are some isolated empirical studies, little rigorous research has been done on how traditional organizations can implement and benefit from OSS practices. This research explores how organizations can foster an environment similar to OSS to manage their software development efforts to reap its numerous advantages: Drawing on organizational theory, we develop a framework that guides the creation and management of a hybrid-OSS community within an organization.

Existing solutions often don't consider about the needs for data security and data privacy. Communication is done without any encryption over insecure networks or with encryption using proprietary solutions, which reduces the data communication possibilities to partners with the same equipment. Our goal was to build a gateway, which offers a transparent solution for secure DICOM-communication in a heterogeneous environment. We developed a PC-based gateway system with DICOM-communication to the in-house network and secure DICOM communication for the communication over the insecure network. One gateway installed at each location is responsible for encryption/decryption. The sender just transfers the image data over the DICOM protocol to the local gateway. The gateway forwards the data to the gateway on the destination site using the secure DICOM protocol, which is part of the DICOM standard. The receiving gateway forwards the image data to the final destination again using the DICOM-Protocol. The gateway is based on Open Source software and runs under several operating systems. Our experience shows a reliable solution, which solves security issues for DICOM communication of image data and integrates seamless into a heterogeneous DICOM environment.","2002","2025-05-05 17:01:25","2025-05-05 17:01:25","","243-251","","NA","4685","","","","PROCEEDINGS OF THE SOCIETY OF PHOTO-OPTICAL INSTRUMENTATION ENGINEERS\n (SPIE)","","","","","","NA","","","","","","","Backup Publisher: SPIE; Amer Assoc Phys Med; Amer Physiol Soc; FDA Ctr Devices & Radiol\n Hlth; Soc Imaging Sci & Technol; Natl Elect Mfg Assoc, Diagnost Imaging\n & Therapy Syst Div; Radiol Soc N Amer; Soc Comp Applicat Radiol ISBN: 0-8194-4430-8 Place: NA Publisher: NA","","","","NA","","Siegel, E.

To this end, we have measured quality characteristics of 100 applications written for Linux, using a software measurement tool, and compared the results with the industrial standard that is proposed by the tool. Another target of this case study was to investigate the issue of modularity in open source as this characteristic is being considered crucial by the proponents of open source for this type of software development. We have empirically assessed the relationship between the size of the application components and the delivered quality measured through user satisfaction.

Open-source software is a recent and important example. Copyright restrictions on open-source projects stipulate that any user may modify the software so long as any resulting innovation is freely available to all. In economic parlance, the innovation is a public good. The economic theory of public-good provision raises a number of important questions. Who contributes to such a project, and who free rides? How might a social planner exploit the interdependence of project components to encourage contributions? Under what conditions will such actions result in successful provision? Using a simple game-theoretic framework and recent results from the study of equilibrium selection, we attempt to answer these questions. Under reasonable assumptions of asymmetry and less than complete information, the most efficient providers will contribute. Contributions can be elicited by `integrating' the provision process when providers are sufficiently optimistic about the success of the project. Otherwise, the social planner may be better off `separating' the components so that individual contributions are independent of each other. The analysis yields recommendations for the leaders of open-source projects and other similar collective-action problems.","2002","2025-05-05 17:01:25","2025-05-05 17:01:25","","446-461","","4","18","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS","","","","Open source software; Collective action; Business And Economics; Copyright; Linux; Success; Operating systems; Public domain; Innovations; Programmers; Public good; Externality; Wildlife conservation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Unlike most previous studies on software evolution that focus on the evolution of the system per se, our study takes a broader perspective: It examines not only the evolution of OSS systems, but also the evolution of the associated OSS communities, as well as the relationship between the two types of evolution.Through the case study, we have found that while collaborative development within a community is the essential characteristic of OSS, different collaboration models exist, and that the difference in collaboration model results in different evolution patterns of OSS systems and communities. To treat such differences systematically, we propose to classify OSS into three types: Exploration-Oriented, Utility-Oriented, and Service-Oriented. Such a classification can provide guidance on the creation and maintenance of sustainable OSS development and communities.","2002","2025-05-05 17:01:25","2025-05-05 17:01:25","","76–85","","NA","NA","","","","IWPSE '02","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 1581135459 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","case study; software evolution; open-source software (OSS); open-source software community","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A survey of recent issues of SIGCSE Bulletin and SIGCSE conference proceedings shows little attention to the role open source software should play in computer science education. We are here to raise the question: ""What are the social and ethical responsibilities of computer science faculty regarding open source software?""One set of issues concerns the use of open source software in teaching and the use of open source development models in the teaching of software development. Some basic questions that arise include ""Should analysis of open source (and possible contributions to it) be the subject of class assignments?"" and ""Should open source software development models be taught?""A second set of issues concerns the use of open source software in support of teaching (e.g., using Linux as your standard platform). Some basic questions that arise include ""Should we use open source software to support teaching?"" and ""Are these faculty ethically obligated to make contributions to the open source software base?""In this panel we will identify many of the parties involved in the ethical and social issues surrounding the use of open source in teaching and in the support of teaching, and we will identify the rights and responsibilities we, as faculty, have to the various parties.

Natural attenuation has as its basis the observation that ecosystem recovery appears to be largely a function of time. Sediment decomposition and the mixing of old sediments by bottom-dwelling organisms contribute to reduced contaminant concentrations. Knowledge of these processes is critical to the development of ecosystem recovery and waste management strategies. To evaluate the applicability of natural attenuation, information should be collected to determine whether surface sediment chemical concentrations will reach cleanup standards within a 10-year period through a combination of natural attenuation and adequate source control. The remedial design for the Thea Foss Waterway Superfund Site in Tacoma, Washington, employs the sequential risk mitigation approach. The EPA has selected a remedy involving natural attenuation (21 acres [8.4 hectares]), enhanced natural attenuation (4 acres [1.6 hectares]), dredging (650,000 cubic yards [494,000 cubic meters]), and capping (30 acres [12 hectares]) of this 8,000-foot (2,438-meter)-long waterway. The dredged material will be disposed of in a near-shore confined disposal facility. Specialized design elements include sorbent capping of active oil seeps, about 400 feet (122 meters) of permanent sheet pile bulkhead, and other features related to long-term monitoring of the remedy and to controlling contaminant sources.","2002","2025-05-05 17:01:27","2025-05-05 17:01:27","","201-209","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Battelle Geneva Res Ctr; Azienda Multiservizi Ambientali Veneziana ISBN: 1-57477-128-0 Place: NA Publisher: NA","","","","NA","","Porta, A.; Hinchee, R.

Following that is a detailed description of GMTK's features, including a language for specifying structures and probability distributions, logarithmic space exact training and decoding procedures, the concept of switching parents, and a generalized EM training method which allows arbitrary sub-Gaussian parameter tying. Taken together, these features endow GMTK with a degree of expressiveness and functionality that significantly complements other publically available packages.

We develop several hypotheses by comparing the Apache project with several commercial projects. We then test and refine several of these hypotheses, based on an analysis of Mozilla data.

Four diamictons interbedded with glaciomarine and glaciofluvial sediments are exposed in a large gravel pit situated above the post-glacial marine limit. The interpretation of these sediments has implications for the history of both the inland ice and the Norwegian Channel Ice Stream. During a Middle Weichselian interstadial, a large glaciofluvial delta prograded into a shallow marine environment along the coast of Jaeren. A minor glacial advance deposited a gravelly journal of Quaternary Science diamicton, and a glaciomarine diamicton was deposited during a following marine transgression. This subsequently was reworked by grounded ice, forming a well-defined boulder pavement. The boulder pavement is followed by glaciomarine clay with a lower, laminated part and an upper part of sandy clay. The laminated clay probably was deposited under sea-ice, whereas more open glaciomarine conditions prevailed during deposition of the upper part. The clay is intersected by clastic dykes protruding from the overlying, late Weichselian till. Preconsolidation values from the marine clay suggest an ice thickness of at least 500 m during the last glacial phase. The large variations in sea-level probably are a combined effect of eustasy and glacio-isostatic changes caused by an inland ice sheet and an ice stream in the Norwegian Channel.

Secure kernel can protect user or system data from unauthorized and/or illegal accesses by applying various access control policies like DAC, MAC, RBAC, and so on. But, even if secure operating system is running under various access control policies, network traffic among these secure operating systems can be captured and exposed easily by network monitoring tools like packet sniffer if there is no protection policy for network traffic among secure operating systems. For this reason, protection for data within network traffic is as important as protection for data within local system. In this paper, we propose a secure operating system trusted channel, SOSTC, as a prototype of a simple secure network protocol that can protect network traffic among secure operating systems and can transfer security information of the subject.

Through the application of both qualitative and quantitative techniques, Samba's software development and evolution over a seven-year period are tracked and assessed.

In particular, examples of how they mitigate and resolve conflict are presented. Conflict arises over the use of a non-free tool to create GNUe graphic, and over the use of a non-free tool for GNUe documentation. The GNUe developers resolve the conflict using internet relay chat (IRC), threaded email discussions, and community digests. We characterize the GNUe developers as an occupational subculture within the occupational community of free/open source software (F/OSS) developers and show how the beliefs in free software and freedom of choice, and values in cooperative work and community assist GNUe contributors in mitigating and resolving conflict. In addition, we show how, despite fluctuating boundaries of membership in a virtual organization, daily discussions on the GNUe IRC serve to build and perpetuate the global community of GNUe contributors as well as F/OSS developers in general.","2003","2025-05-05 17:01:29","2025-05-05 17:01:29","","21–30","","NA","NA","","","","GROUP '03","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 1581136935 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","conflict; organizational culture; virtual organization; computer-supported cooperative work; free/open source software development; occupational community","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We find that the Apache field support system functions effectively. We also find that, when we partition the help system into its component tasks, 98% of the effort expended by information providers in fact returns direct learning benefits to those providers. This finding considerably reduces the puzzle of why information providers are willing to perform this task “for free.” Implications are discussed. (C) 2002 Elsevier Science B.V.

Against conventional wisdom this approach has been wildly successful in the general software market-probably because the openness lets programmers the world over obtain, critique, use, and build upon the source code without licensing fees. Linux, a UNIX-like operating system, is the best known success. But computer scientists at the University of California, Berkeley began the tradition of software sharing in the mid 1970s with BSD UNIX and distributed the major internet network protocols as source code without a fee. Medical informatics has its own history of Open Source distribution: Massachusetts General's COSTAR and the Veterans Administration's VISTA software have been distributed as source code at no cost for decades. Bioinformatics, our sister field, has embraced the Open Source movement and developed rich libraries of open-source software. Open Source has now gained a tiny foothold in health care (OSCAR GEHR, OpenEMed). Medical informatics researchers and funding agencies should support and nurture this movement. In a world where open-source modules were integrated into operational health care systems, informatics researchers would have real world niches into which they could engraft and test their software inventions. This could produce a burst of innovation that would help solve the many problems of the health care system.

Some people suggest open-source software developers freely reveal and share because they garner personal benefits from doing so, such as learning to develop complex software. Open-source projects can be started by anyone with the appropriate programming skills and motives. In the future, some managers may encourage the use of open-source software in their own firms. Others may attempt to build a business based on distributing and servicing open-source software. The open-source software movement also provides important management lessons regarding the most effective ways to structure and implement innovation. The lessons of open-source projects demonstrate the value of specialization through self-selection and how norms of meritocracy and peer recognition help ensure product quality.","2003","2025-05-05 17:01:30","2025-05-05 17:01:30","","14–18","","3","44","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Innovation; Open source; Software; Open-source software; Licenses; Product development; Trends; Internet; Software development; Meritocracy; 5240:Software & systems; Public domain; Freeware; Developer; Innovations; 9190:United States; Defense contracts; Laboratories; Organization studies; Open; Programmer; Public good; Computer programming; Projects; Self-selection bias; User needs; United States–US; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open-source software provides the building blocks for advanced geospatial archiving, processing, and distribution. Recently, robust open-source software solutions have Proliferated in remote sensing, geographical information systems, spatial data engines, and relational databases. Additionally, advanced supercomputing capabilities with clusters of commodity personal computers can be applied to the management and processing of extremely large data sets. These advances have been integrated into highly-leveraged systems that can be applied to a wide array of remote sensing and geospatial activities. The authors describe the various technologies currently available and how these technologies have been integrated into an online Data Management System. Examples of the application of this system to multiple application areas are described Examples include custom processing and organization of satellite, aerial, raster map, and vector data sets.","2003","2025-05-05 17:01:30","2025-05-05 17:01:30","","651-653","","NA","NA","","","","IEEE International Symposium on Geoscience and Remote Sensing (IGARSS)","","","","","","NA","","","","","","","Backup Publisher: IEE; IEEE Geosci & Remote Sensing Soc; Ctr Natl Etudes Spatiales; NASA;\n Natl Ocean & Atmospher Adm, US Dept Commerce; Off Naval Res; eesa;\n NPOESS; NASDA; Ball Aerosp & Technol Corp; uRSi ISBN: 0-7803-7929-2 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Comparing to traditional software engineering approach, we found this approach is absolutely reversed. Open source development and delivery occurs on Internet time. Developers are not confined to a geographic area. They work voluntarily on a project of their choice; they are not forced to join a particular project just because it needs more developers or the project has a high degree of urgency. Developers work for peer-recognition and self-satisfaction. In the open source community, each and every project has an equal priority. Software designed under open source is not released until the project owner thinks that the software has reached a functional stage. One of the success stories is the Linux operating system. Open Source software is always in an evolutionary stage: it never reaches a final stage. As new requirements emerge the software is enhanced by the user/developers. In this paper, we give an introduction to the insights of open source software development. We then elucidate the perceived benefits and point out the differences between open source and closed source software development approaches. At the end we propose a new model for open source software development.","2003","2025-05-05 17:01:31","2025-05-05 17:01:31","","136-143","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: Int Inst Informat & System ISBN: 980-6560-01-9 Place: 14269 LORD BARCLAY DR, ORLANDO, FL 32837 USA Publisher: INT INST INFORMATICS & SYSTEMICS","","","","NA","","Callaos, N.; Lesso, W.; Schewe, K.

From standards literature we distil four categories of coordinative mechanisms, and illustrate their relevance with OSS examples.

The purpose of this study was to analyse the amount of Bio-Oss ossification in a case of maxillary sinus augmentation, recording and comparing histomorphometric data 8 months, 2 and 10 years after surgery. This long-term histologic evaluation of retrieved specimens has been performed, comparing histomorfometric measures at different times. Eight months after surgery we observed in 20 different thin sections of the specimen a mean amount of bone tissue (including medullar spaces) of 29.8% (and 70.2% of Bio-Oss) +/- 2.6. At 2 years the bone tissue increased to 69.7% + 2.7 and 10 years after surgery it was 86.7% +/- 2.8. The comparison of the means for each time has shown a highly significant increasing trend in bone formation associated with Bio-oss resorption: at 8 months, 2 and 10 years.","2003-06","2025-05-05 17:01:31","2025-05-05 17:01:31","","369-372","","3","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 35 NORRE SOGADE, PO BOX 2148, DK-1016 COPENHAGEN, DENMARK Publisher: BLACKWELL MUNKSGAARD","","","","anorganic bovine bone; Bio-oss; maxillary sinus augmentation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The OSS technique allows for the rapid calculation of radiance for any class of multispectral, hyperspectral, or ultraspectral sensors at any spectral resolution operating in any region from microwave through UV wavelengths by selecting and appropriately weighting the monochromatic points that contribute over the sensor bandwidth. This allows for the calculation to be performed at a small number of spectral points while retaining the advantages of a monochromatic calculation such as exact treatment of multiple scattering and/or polarization. The OSS method is well suited for remote sensing applications which require extremely fast and accurate radiative transfer calculations: atmospheric compensation, spectral and spatial feature extraction, multi-sensor data fusion, sub-pixel spectral analysis, qualitative and quantitative spectral analysis, sensor design and data assimilation. The OSS was recently awarded a U.S. Patent (#6,584,405) and is currently used as part of the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) CrIS, CMIS, and OMPS-IR environmental parameter retrieval algorithms. This paper describes the theoretical basis and development of OSS and shows examples of the application and validation of this technique for a variety of different sensor types and applications.","2004","2025-05-05 17:01:33","2025-05-05 17:01:33","","368-374","","NA","5425","","","","PROCEEDINGS OF THE SOCIETY OF PHOTO-OPTICAL INSTRUMENTATION ENGINEERS\n (SPIE)","","","","","","NA","","","","","","","Backup Publisher: SPIE ISBN: 0-8194-5348-X Place: NA Publisher: NA","","","","NA","","Shen, S.

In this paper, I intend to examine some of the self-conscious ambiguities of the role-playing narrator of The Mill on the Floss. The use of the male narrator is inseparably bound up with a number of compromises for the woman writer and for the female reader. But being thus `compromised' through vicariously living the experience of the masculine Other also allows the woman writer privileged insight into the complex processes of justification and rationalisation through which the masculine world-view is engendered and sustained in narrative; it allows her imaginatively to work through, and to see through, the tangle of cause and effect relations which are often illegitimately marshalled into support of that view, and to cast ironical and critical light on them.","2004-04","2025-05-05 17:01:33","2025-05-05 17:01:33","","230-250","","59","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAHIERS VICTORIENS EDOUARDIENS PO 5043, 34032 MONTPELLIER-CEDEX, FRANCE Publisher: UNIV PAUL VALERY","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although this process is crucial to the success of free software projects, there is more to the free software development than the creation of a 'bazaar'. In this paper we draw on existing free software projects to define a lifecycle model for free software. This paper then explores each phase of the lifecycle model and agrees that, while the bazaar phase attracts the most attention, it is the initial modular design that accommodates diverse interventions.

A methodology to integrate GIS and statistics in morphometric analysis is presented for the most usual morphometric parameters-hypsometry, slope, aspect, swath profiles, lineaments and drainage density, surface roughness, isobase and hydraulic gradient. The GIS used was the Geographic Resources Analysis Support System (GRASS-GIS), an open-source project that offers an integrated environment for raster and vector analysis, image processing and maps/graphics creation. Statistical analysis of parameters can be carried out on R, a system for statistical computation and graphics, through an interface with GRASS that allows raster maps and points files to be treated as variables for analysis. The basic element for deriving morphometric maps is the digital elevation model (DEM). It can be interpolated from scattered points or contours, either in raster or vector format; it is also possible to use DEMs from NASA's Shuttle Radar Topographic Mission, with 30 m of ground resolution for the USA and 90 m for other countries. Proposed methodology can be adapted according to necessities and available tools. The use of free and open-source tools guarantees access to everyone, and its increasing popularization opens new development perspectives in this research field. (C) 2004 Elsevier Ltd.

As a consequence open source software is now viewed more favourably than in the past, with increased penetration in all markets. Despite the success of these inroads and the cost savings involved in switching to open source software, proprietary software remains far and away the predominant product of choice. In this paper we discuss some results of research into why public and private organisations select a particular software solution over another. We examine the criteria that make one item of software more attractive to an organisation and compare and contrast software selection in both the public and private sectors. Ultimately we show that OSS is a competitive alternative to proprietary software and that the criteria on which organisations base their software selection, can be met by OSS products.","2004","2025-05-05 17:01:34","2025-05-05 17:01:34","","162-167","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: Int Inst Informat & Syst; Int Federat Syst Res ISBN: NA Place: 14269 LORD BARCLAY DR, ORLANDO, FL 32837 USA Publisher: INT INST INFORMATICS & SYSTEMICS","","","","NA","","Carrasquero, J.

The software is developed in Objective-C on a Macintosh platform under the MacOS X operating system using the GNUstep development environment. It also benefits from the extremely fast and optimized 3D graphic capabilities of the OpenGL graphic standard widely used for computer games optimized for taking advantage of any hardware graphic accelerator boards available. In the design of the software special attention was given to adapt the user interface to the specific and complex tasks of navigating through large sets of image data. An interactive jog-wheel device widely used in the video and movie industry was implemented to allow users to navigate in the different dimensions of an image set much faster than with a traditional mouse or on-screen cursors and sliders. The program can easily be adapted for very specific tasks that require a limited number of functions, by adding and removing tools from the program's toolbar and avoiding an overwhelming number of unnecessary tools and functions. The processing and image rendering tools of the software are based on the open-source libraries ITK and VTK. This ensures that all new developments in image processing that could emerge from other academic institutions using these libraries can be directly ported to the OsiriX program.

Although resistance manifests itself in numerous ways, resistance to change is frequent when individuals are introduced to new ideas or innovations. This form of resistance can limit forward progress of either an individual or an organization. However, a few papers investigated possible positive roles of resistance in human life. This paper proposes that resistance can be a positive motivator to achieve change. Open source software (OSS) is a technological innovation that is laden with aspects of resistance. One of the initial motivations for the development of open source software was ""psychological reactance"" on the part of a few software developers. Reactance is a limited part of the overall construct of resistance; specifically, resistance caused by external threats to an individual's freedom of choice, which generally manifests itself affectively. This paper looks at the role of resistance as a motivator for technological innovation from the perspective of open source softwre development. It also presents techniques for overcoming resistance to the adoption of open source software. Specific techniques presented are the Alpha and Omega strategies for overcoming resistance. Alpha strategies work by attempting to increase the approach forces towards some goal. Conversely, Omega strategies attempt to decrease the avoidance forces, thereby removing resistance to change. Both techniques are used in the context of open source software development to motivate participants.","2004","2025-05-05 17:01:36","2025-05-05 17:01:36","","36","","NA","13","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Innovation; Motivation; Resistance; Open source; Open-source software; Software development; Public domain; Innovations; Programmer; Reactance; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Creating this technology requires designing, implementing, debugging and testing software applications on a continual basis. Furthermore current software development is typically performed in a distributed environment involving many developers. While the use of open-source software may create collaborative communities that enhance overall technology exchange, it does nothing directly to manage change nor does it address the quality of the underlying software. This paper describes a software development process that has proven vital to the success of the widely used open-source toolkits ITK (itk.org) and VTK (vtk.org). This process facilitates cross-platform development, includes automatic documentation generation, integrates continuous testing, and posts the results of the process on publicly accessible web pages. The net result is that a responsive feedback loop is created between the developers in the community and automated processes to measure software quality. With this process software converges towards better software as long as the process is enforced. The tools described here are open-source and available for use in academic and commercial applications.","2004","2025-05-05 17:01:36","2025-05-05 17:01:36","","648-651","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: IEEE ISBN: 0-7803-8388-5 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The Mill on the Floss is thus a novel whose structure is wholly based on the blending of several types and subgenres. The novel itself depends on the combination of several discourses, which enrich each other and obliquely create the conditions of their compatibility. The very end of the novel thus benefits from the melodramatic dimension and tradition it seems to imitate, whereas the novel itself cannot be termed a melodrama. In The Mill on the Floss, each subgenre directly redefines George Eliot's novel and creates the possibility of the blending of different genres and types.","2004-04","2025-05-05 17:01:36","2025-05-05 17:01:36","","295-306","","59","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper reports on a survey-based study that investigated user collaboration in open source development. Among the many interesting results, we found open source users themselves to be very experienced software developers. They are highly motivated to make their own contributions, work closely with developers on various tasks, and use electronic communication tools extensively. Users with different development experience and contributing to different category of projects tend to exhibit different motivations and behaviours. These findings confirm the differences between traditional and open source user collaboration and their implications for future open source evolution and management are given and discussed in this paper.

Second, our more long term objective is to develop tools to assist OSS developers to extract and reconstruct design relevant information from previous discussions. We show how quotation practices can be used to locate design relevant data in discussion archives. OSS developers use quotation as a mechanism to maintain the discursive context. To retrace thematic coherence in the online discussions of a major OSS project, Python, we follow how messages are linked through quotation practices. We compare our quotation-based analysis with a more conventional, thread-based analysis of the (reply-to) links between messages. The advantages of a quotation-based analysis over a thread-based analysis are outlined. Our approach provides a means to analyze argumentation and design rationales and promises a novel means to discover design relevant information in the archives of online discussions. Our analysis reveals also the links between the social structure and elements in the discussion space and how it shapes influence in the design process.","2005","2025-05-05 17:01:37","2025-05-05 17:01:37","","301-320","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Convivio; Univ Milano Bicocca, Dept Informat, Syst & Commun; Univ\n Milano ISBN: 1-4020-3590-X Place: NA Publisher: NA","","","","NA","","VandenBesselaar, P.; DeMichelis, G.; Preece, J.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The framework comprised four macro-factors - external environment, organisational context, technological context and individual factors. We then investigated these factors in a large-scale survey. Overall, the findings suggest a significant penetration of OSS with general deployment in two industry sectors consultancy/sotware house and service/communication - and more limited deployment in government/public sector. However, the existence of a coherent and planned IT infrastructure based on proprietary; software served to impede adoption of OSS.

The conclusions from Orbotech experience are that when carefully planned and implemented, software reuse provides the anticipated benefits of cost reduction, improved quality and shorter Time-to-Market. The reuse of OSS may provide even higher benefits than conventional software reuse. Nevertheless, as in many cases before, implementation of software reuse requires management support and commitment, as well as acceptance by the developers themselves.

As a first implementation, it is assumed that the forward models are perfect and that the radar data are sampled at the analysis grid points. A general purpose nonhydrostatic compressible model is used with the inclusion of complex multiclass ice microphysics. New aspects of this study compared to previous work include the demonstration of the ability of the EnKF method to retrieve multiple microphysical species associated with a multiclass ice microphysics scheme, and to accurately retrieve the wind and thermodynamic variables. Also new are the inclusion of reflectivity observations and the determination of the relative role of the radial velocity and reflectivity data as well as their spatial coverage in recovering the full-flow and cloud fields. In general, the system is able to reestablish the model storm extremely well after a number of assimilation cycles, and best results are obtained when both radial velocity and reflectivity data, including reflectivity information outside of the precipitation regions, are used. Significant positive impact of the reflectivity assimilation is found even though the observation operator involved is nonlinear. The results also show that a compressible model that contains acoustic modes, hence the associated error growth, performs at least as well as an anelastic model used in previous EnKF studies at the cloud scale. Flow-dependent and dynamically consistent background error covariances estimated from the forecast ensemble play a critical role in successful assimilation and retrieval. When the assimilation cycles start from random initial perturbations, better results are obtained when the updating of the fields that are not directly related to radar reflectivity is withheld during the first few cycles. In fact, during the first few cycles, the updating of the variables indirectly related to reflectivity hurts the analysis.

Mass-market consumers can be divided between those who are informed about the existence of OSS and those who are uninformed. Since OSS producers have little incentive to advertise, there may be a substantial mass of uniformed consumers, leading to market failures that may justify government intervention. We study three government policies: (a) mandated adoption, whereby the government forces public agencies, schools, and universities to adopt OSS, (b) information provision, whereby the government informs the uninformed users about the existence and the characteristics of OSS, and (c) subsidy, whereby the government makes a payment to consumers if they adopt OSS. We show that mandated adoption and information provision may increase social welfare, but the subsidy always reduces it. When network externalities are added to the model, we show that mandated adoption and information provision may increase social welfare if they help the market to tip towards standardization.","2005-03","2025-05-05 17:01:39","2025-05-05 17:01:39","","217-240","","2","26","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Public Health; Open source; Software; Open-source software; Public policy; Public domain; 8302:Software & computer services industry; 1200:Social policy; 7000:Marketing; Government subsidies; Mass market; Mass markets; Network effect; Subsidies; Welfare; Business And Economics–Management; 92313:Administration of Human Resource Programs (except Education; Veterans' Affairs Programs)","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bio-Oss (R) is a deproteinized, sterilized bovine bone that has been extensively used in bone regeneration procedures. The aim of the present study was a comparative light, scanning, and electron microscopy evaluation of the interface between Bio-Oss (R) and bone in specimens retrieved after sinus augmentation procedures. Under light microscopy, most of the particles were surrounded by newly formed bone, while in a few cases, at the interface of some particles it was possible to observe marrow spaces and biological fluids. Under scanning electron microscopy, in most cases, the particle perimeter appeared lined by bone that was tightly adherent to the biomaterial surface. Transmission electron microscopy showed that the bone tissue around the biomaterial showed all the phases of the bone healing process. In some areas, randomly organized collagen fibers were present, while in other areas, newly formed compact bone was present. In the first bone lamella collagen fibers contacting the Bio-Oss (R) surface were oriented at 243.73 +/- 7.12 degrees (mean +/- SD), while in the rest of the lamella they were oriented at 288.05 +/- 4.86 degrees (mean +/- SD) with a statistically significant difference of 44.32 degrees (p < 0.001). In the same areas the intensity of gray value was 172.56 +/- 18.15 (mean +/- SD) near the biomaterial surface and 158.71 +/- 21.95 (mean +/- SD) in the other part of the lamella with an unstatistically significant difference of 13.79 (P = 0.071). At the bone-biomaterial interface there was also an electron-dense layer similar to cement lines. This layer had a variable morphology being, in some areas, a thin line, and in other areas, a thick irregular band. The analyses showed that Bio-Oss (R) particles do not interfere with the normal osseous healing process after sinus lift procedures and promote new bone formation. In conclusion, this study serves as a better understanding of the morphollogic characteristics of Bio-Oss (R) and its interaction with the surrounding tissues.

NAICS is considered a rational system that uses the underlying economic principle of similar production processes as the basis for its classes. For the Information Sector of the economy, as formulated in NAICS, a key production process is the acquisition and defense of copyright. With open source, copyleft licensing eliminates copyright acquisition and protection as major production processes, suggesting that the open source software industry warrants a separate NAICS category.

A key success factor is to respond to customers' desires to choose the billing scheme that suits their needs, to subscribe to all services as a service package, and to pay for them via a single bill regardless of service type, service location, service providers and network operators. Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task. This paper presents key OSS functions and an information model that tackle this complexity. Challenges are described and requirements are defined. Related efforts are highlighted, and the context surrounding this work is laid out in detail. Finally, individual entities of information model and OSS functions are defined and an example using flow-chart to illustrate interaction of functions is presented.","2005","2025-05-05 17:01:40","2025-05-05 17:01:40","","717-730","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: IFIP; IEEE Commun Soc ISBN: 0-7803-9087-3 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","federated accounting management; billing schemes; charging; credit control; service\n package; usage","","Clemm, A.; Festor, O.; Pras, A.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation.

OSS has existed as a model for developing computer applications and software since the 1950s. However, OSS has only found its way into the public arena within the past decade due to some major projects gaining significant market share from commercial developers such as Microsoft. Research in the area of OSS has become more extensive in recent years and has examined areas such as motivation of programmers as well as the benefits of OSS. However, literature focusing on the actual implementation of OSS is more limited with only Fitzgerald and Kenny [(2004). Developing an information infrastructure with Open Source Software. IEEE Software, 50-55] providing any substantial analysis of how it might be achieved. In this paper the focus is on OSS use and implementation within the UK public sector. This sector has a history of resource wastage and underperforming information systems. The underpinning issues of motivation and benefits to organisations will be addressed along with the difficulties that the UK Government faces in adopting an OSS strategy. Section 2 examines the existing literature in the area and explores why OSS should be adopted and implemented by the public sector in the UK. Section 3 considers the research approach taken and the results obtained from considering the implementation of OSS in eight government organisations. Section 4 concludes with a discussion and some implications for those organisations in the public sector who might wish to take this approach.

In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis. Ultimately, this is intended to be a public software resource that will serve as a foundation for future medical image research.","2005-02","2025-05-05 17:01:41","2025-05-05 17:01:41","","NA","","2","48","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Collaboration; Computer science; Open-source software; Research; Visualization; Software utilities; Software development; Architecture; 5240:Software & systems; Public domain; Engineering; 5400:Research & development; 9190:United States; Research & development; Application programming interface; Interfaces; 8320:Health care industry; Digital image processing; Image; Medical imaging; United States–US; Research & development–R&D; Computers–Data Communications And Data Transmission Systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the evaluation of its success is limited to histological analysis, and its effects on mechanical hardness remain to be investigated. This study investigated mechanical strength in support of histological findings, specifically for tissue-engineered bone with mesenchymal stem cells (MSCs) and platelet-rich-plasma (PRP). Initially, teeth were extracted, and bone defects on both sides of the mandible were prepared with a trephine bar. The defects were implanted by using the following graft materials: 1) PRP, 2) PRP and dog MSCs (dMSCs), 3) autogenous bone (PCBM), 4) bone substitute (Bio-Oss (R)), and 5) control (defects only). After 2, 4, 8, and 12 weeks of implantation, the defects were histologically assessed to examine their mechanical properties. According to histological observations, the dMSCs/PRP groups had well-formed mature bone compared with the control (defects only), Bio-Oss (R), and PRP groups. The Vickers hardness test values were 8 (control), 9 (PRP), not detected (Bio-Oss (R)), 11 (PCBM), and 17 (dMSCs/PRP) after 2 weeks. Therefore, tissue-engineered bone can be used for early stage bone regeneration from the viewpoint of histology and mechanical properties.

The focus of the paper lies in a proof-of-concept for a novel means to develop and execute pervasive services, with simplicity and maintainability as prime drivers. The essence of this approach is the novel integration of the policy-based management (PBM) techniques and the model-driven architecture (MDA) techniques for specifying pervasive services and their behaviour, together with auto-generation of middleware implementation and policy enablement. The presence of policies provides pervasive services with the high flexibility and adaptability needed for dealing with changing environments and resource availabilities, while the introduction of MDA for defining pervasive service information models fundamentally solves the information modelling puzzle of current policy-based approaches. Additionally, MDA's middleware-neutral feature benefits the smooth evolution of pervasive services as a piece of software artefact in the face of heterogeneous devices and platforms. A preliminary case study has demonstrated the practical feasibility and benefits of this approach. The case study revolves around an ICT service called TEANU - transparent enterprise access for nomadic user. The service provides a means for nomadic users to maintain a secure access to their enterprise network in the presence of multiple access network providers with different service level guarantees.","2005-07","2025-05-05 17:01:42","2025-05-05 17:01:42","","162-174","","3","23","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Infrastructure; Studies; Software; Case studies; Wireless networks; Internet service providers; Engineering; 9130:Experimental/theoretical; 5220:Information technology management; Adaptability; Communications networks; 8331:Internet services industry; Logic; Middleware; Model-driven architecture; Operation support systems; Policy-based management; Virtual offices; Communications–Telephone And Telegraph; 51711:Wired; Wireless Telecommunications Carriers (except Satellite)","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such social conventions legitimise value and provide identification in the global online community and have important implications for service industries in general.","2005-09","2025-05-05 17:01:43","2025-05-05 17:01:43","","789-801","","6","25","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Social research; Open source; Online community; Open-source software; 5240:Software & systems; Public domain; 9130:Experimental/theoretical; Network effect; 1220:Social trends & culture; 8300:Service industries not elsewhere classified; Service industries; Business And Economics–Labor And Industrial Relations","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are continuing debates over the future of software and, in particular, the competition between OSS and proprietary software. Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. The government environment is changing rapidly in areas as diverse as homeland security and social services. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied-especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.","2005","2025-05-05 17:01:43","2025-05-05 17:01:43","","227-238","","2","44","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1 NEW ORCHARD ROAD, ARMONK, NY 10504 USA Publisher: IBM CORP","","","","Open source software; Computers; Information technology; Studies; Open source; Open-source software; Linux; Government; Software development; Interoperability; Electronic government; 5240:Software & systems; Public domain; Proprietary; Open standard; 9130:Experimental/theoretical; Citizens; Comparative analysis; Cost reduction; Equipment acquisition planning; Government agencies; Open standards; Technology standards","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We show how quotation practices can be used to locate design relevant data in discussion archives. OSS developers use quotation as a mechanism to maintain the discursive context. To retrace thematic coherence in the online discussions of a major OSS project, Python, we follow how messages are linked through quotation practices. We compare our quotation-based analysis with a more conventional analysis: a thread-based of the reply-to links between messages. The advantages of a quotation-based analysis over a thread-based analysis are outlined. Our analysis reveals also the links between the social structure and elements in the discussion space and how it shapes influence in the design process.","2005","2025-05-05 17:01:44","2025-05-05 17:01:44","","177–186","","NA","NA","","","","GROUP '05","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 1595932232 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software projects; distributed asynchronous design; quoting practices","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Instead of a monolithic master system, small tools with a limited set of tasks are interconnected using standardized, self-descriptive data structures. This approach is highly flexible with respect to the rapidly changing needs of the scientists: Since the modules are isolated and intermodule communication is standardized, new components can be integrated without side effects. The developed software environment follows to a large extent the UNIX design philosophy and is heavily based on open-source software technologies that are used to solve specific tasks within the overall system to achieve high productivity in using the software for ambitious high-throughput experimentation programs. It is shown that the orchestration of the system significantly benefits from clear and standardized interface design based on hteML, the high-throughput experimentation markup language, an XML language for the description of high-throughput experimentation data and processes.

Open source software (OSS) has challenged much of the traditional reasoning by suggesting that individuals behave altruistically and contribute to a public good, despite the opportunity to free-ride. The lion's share of the existing literature on OSS examines communities, that is, those individuals whom are already part of the OSS community. In contrast, this paper starts from users with the requisite skill to use and develop OSS. This group of skilled individuals could potentially invest into the development of OSS knowledge, but they may or may not do so in actuality. This paper, therefore, explores three issues, which have not been extensively explored in the literature, namely, (1) how frequently a group of skilled people use OSS, (2) reasons for differences among users and non-users in terms of use and attitudes, and (3) how frequently, and why, some users contribute to OSS projects (and thereby become developers). In doing so, we consider the opportunity costs of use and development of OSS, which has been largely neglected in the literature. We find that the individuals have a rather pragmatic attitude to firms and that many are active in both firms and OSS community, which raises many questions for future research about the role and influence of firms on the development and diffusion of OSS.","2005-10","2025-05-05 17:01:44","2025-05-05 17:01:44","","617-635","","7","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Open source; Open-source software; Knowledge; Software development; Public domain; Developer; Technology: Comprehensive Works; 9130:Experimental/theoretical; 1130:Economic theory; Economic theory; 5200:Communications & information management; Investment; Opportunity costs","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In OSS architecture, overlay server nodes (OSN) are distributed across the core network architecture of the mobile operator and each node is responsible for both running the game applications and performing the overlay routing. The architecture allows third party game servers that are located outside the core network of the mobile operator to push the execution of delay and bandwidth constrained game components into the core to achieve better quality of service (QoS). When a game consists of multiple mutually exclusive game objects such that each object can be maintained independently, OSS allows per object QoS optimization via selecting the jointly optimal location (i.e. OSN) and overlay routes for each object. This fine-grain optimization benefits most when different objects have different QoS requirements and they are accessed by different users. OSS dynamically adapts to the changes in game and network conditions by switching to better OSN and overlay routes. Our performance analysis on different core network topologies and usage patterns demonstrates that OSS has significant advantages over the alternative peer to peer (P2P), proxy-server, and client-server architectures. The analysis also underlines the individual contributions of object placement and jointly performed overlay route optimization to the performance gain.","2006","2025-05-05 17:01:45","2025-05-05 17:01:45","","NA","","NA","NA","","","","IEEE Global Telecommunications Conference (Globecom)","","","","","","NA","","","","","","","Backup Publisher: IEEE Commun Soc (ComSoc) ISBN: 978-1-4244-0356-1 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using a qualitative research approach, we highlight the existence of a new context, in which the adoption of Linux-based OSS platforms by companies is not led only by traditional drivers. User communities and broader social responsibility considerations have been found to exert some degrees of pressure on the IT decision maker.

Refactoring refers to the restructuring of software according to specific mechanics and principles. In this paper, we describe an analysis of the results from a tool whose purpose was to identify and extract refactorings from seven open-source Java systems. In particular, we analyzed the mechanics of the most commonly and least commonly applied refactorings to try and account for their frequency. Results showed the most common refactorings of the fifteen coined a 'Gang of Six', to be generally those with a high in-degree and low out-degree when mapped on a dependency graph; the same refactorings also featured strongly in the remedying of bad code smells. Remarkably and surprisingly, inheritance and encapsulationbased refactorings were found to have been applied relatively infrequently - we offer explanations for why this may be the case. The paper thus identifies 'core' refactorings central to many of the changes made by developers on open-source systems. While we can not guarantee that developers consciously undertake refactoring in any sense, the empirical results demonstrate that simple renaming and moving fields/methods between classes are common components of open-source system re-engineering. From a wider software engineering perspective, knowledge of what a modification will incur in likely sub-tasks is of value to developers whether working on open-source or other forms of software.","2006","2025-05-05 17:01:46","2025-05-05 17:01:46","","288–296","","NA","NA","","","","ISESE '06","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 1595932186 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","code smells; refactoring; taxonomy; testing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Being able to identify the core members of a FLOSS development project is important because many of the processes necessary for successful projects likely involve core members differently than peripheral members, so analyses that mix the two groups will likely yield invalid results. We compare 3 analysis approaches to identify the core: the named list of developers, a Bradford's law analysis that takes as the core the most frequent contributors and a social network analysis of the interaction pattern that identifies the core in a core-and-periphery structure. We apply these measures to the interactions around bug fixing for 116 SourceForge projects. The 3 techniques identify different individuals as core members; examination of which individuals are identified leads to suggestions for refining the measures. All 3 measures though suggest that the core of FLOSS projects is a small fraction of the total number of contributors.","2006","2025-05-05 17:01:46","2025-05-05 17:01:46","","118.1","","NA","NA","","","","HICSS '06","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 0769525075 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Refactoring refers to the restructuring of software according to specific mechanics and principles. In this paper, we describe a tool that allows refactoring data across multiple versions of seven open-source software systems to be collected. The tool automates the identification of refactorings as program transformations between consecutive software releases. The same tool thus allowed an empirical analysis of software development across versions from the perspective of those transformations. We describe results for the systems analysed and point to key conclusions from our analysis. In particular, we investigate a problematic empirical question as to whether certain refactorings are related, i.e., they cannot be undertaken in isolation without other refactorings being undertaken in parallel. In this context, we focus specifically on the four most common refactorings identified by the tool from three of the open-source systems and use a dependency graph to inform conclusions about the empirical data extracted by the tool.

From a constructionist perspective, the democratic effects of non-proprietary software are contingent on how the practice of free and open-source software is discursively represented and constituted as it is translated into new e-government systems. On these premises, an analysis of official discourse and government policy for non-proprietary software suggests that its introduction into government will bring more politics as usual rather than democratisation. Nevertheless, on the basis of an alternative discourse of ethics and freedom evident in the Free Software and Open Source communities, the authors of this paper envisage circumstances in which the discourse and practice of non-proprietary software contribute to opening-up and democratising e-government, by protecting and extending transparency and accountability in e-governments and by offering scope for technology to be shaped by citizens and associations as well as by administrators and private interests.

We will show that the reality is more complex and that there is a significant difference: the free software community uses primarily non-legal enforcement methods and trusts on social norms. We argue that free software could be used as a tool to make copyright more accepted in the less developed world because of its positive connection with copyright and community based approach.

The copyright regime is so restrictive that it turns a normal learning process into a series of potential copyright violations. The Free Software Movement (FSM) represents a substantial community effort to counter this trend. It seeks to supersede the copyright regime by offering the `Copyleft' licensing mode, which facilitates the formation of a cooperative, resource- sharing community. The FSM has been so successful that it has challenged the utilitarian values presumed in copyright law, has fuelled widespread reassessment of copyright law, and has influenced many who engage in various creative activities. Claiming to bear similar values, Creative Commons (CC) provides licensing models for people to waive some rights granted to them. However, CC differs from the FSM in significant ways. Most notably, the flexible CC licensing model weakens the firm philosophical and political ground which binds FSM advocates together. Hence, although CC's rapid growth seems to signal its success, it is questionable whether such success is as enduring as the FSM's, or if it is leading to a different result. While CC champions the author's freedom to decide how to use his or her bundle of property rights granted by copyright law, the FSM advocates the freedom to build and live in an alternative, vital and self- sustaining community. The existence of such an alternative model not only allows these particular participants to be independent from the proprietary world, but also may empower the rest of society to imagine different kinds of relationships between human beings and their creative activities.","2006-12","2025-05-05 17:01:48","2025-05-05 17:01:48","","337-347","","4, SI","4","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study demonstrates both the benefits and the risks of government policy favoring FLOSS from the perspective of economics, technology, and politics, and to further analyze whether these same policy goals can be achieved through government support of FLOSS. The most fundamental argument of the study is that, in lending its support to FLOSS, the difference between a government user and a business user is that the government should take into account society's long-term interests, not merely its own interests as a consumer.[PUBLICATION ABSTRACT]","2006","2025-05-05 17:01:48","2025-05-05 17:01:48","","113–141","","4","18","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Sociology; Open source; Open-source software; Public policy; Open data; Open innovation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted social network analyses of bug-fixing interactions from three repositories: Sourceforge, GNU Savannah and Apache Bugzilla. We find that some OSS teams are highly centralized, but contrary to expectation, others are not. Projects are mostly quite hierarchical on four measures of hierarchy, consistent with past research but contrary to the naive image of these projects. Furthermore, we find that the level of centralization is negatively correlated with project size, suggesting that larger projects become more modular, or possibly that becoming more modular is a key to growth. The paper makes a further methodological contribution by identifying appropriate analysis approaches for interaction data. We conclude by sketching directions for future research.[PUBLICATION ABSTRACT]","2006","2025-05-05 17:01:48","2025-05-05 17:01:48","","65–85","","4","18","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Remote work; Sociology; Social network analysis; Open source; Software; Open-source software; Hierarchy; Public domain; Centralisation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The paper finds that as users become more skilled in OSS, the price of proprietary software will decline. Second, the equilibrium market structure is influenced by both users' expertise and network effects. It is not surprising that proprietary software can drive OSS out of the market in presence of network effect, but counter-intuitively, this happens when users are highly skilled in OSS.

Some countries have successfully created extensive information technology infrastructures, yet software use continues to be reliant on pirated sources. The experiences of licensing regulation violations and increasing virus attacks indicate that part of the problem is a consequence of dependencies created by the use of proprietary software within resourcescarce economies. Recent growth in the use of free and open-source software (FOSS) by various public-and private-sector agencies suggests an alternative path to software self-suffciency for a resource-scarce country like Cuba. There is, however, an interesting background to current software use within Cuba that makes it unique among several less-developed countries. Apart from the well-known advantages, FOSS use could be essential to shape the future scenario of Cuba. The present paper first delineates some of the Cuban background, basically characterized by lack of freedom in technology ownership and access to external information. The potential of FOSS use within existing conditions in Cuba is then analyzed. Finally, conclusions are provided on the basis of a survey carried out in Cuba, arguing that there needs to be stronger political will to reduce gaps between goals and implementation reality to achieve intrinsic advantages of FOSS use successfully.","2006","2025-05-05 17:01:49","2025-05-05 17:01:49","","1-17","","1","3","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: UNIV SOUTHERN CALIFORNIA, KERCKHOFF HALL, 734 W ADAMS BLVD, MC7725, LOS\n ANGELES, CA 90089 USA Publisher: USC ANNENBERG PRESS","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It could also promote an IP generating capacity in developing countries. An examination of the status of free or open source software in developing countries in Southeast Asia reveals that governments in these countries are aware of FOSS and wish to foster its use (but face considerable pressure to use proprietary software).

However, these wonderful applications come at a price and may be beyond the financial scope of many.

Maintenance effort is usually measured in person-hours used to perform a maintenance task. However, maintenance effort data are usually only available for strictly managed software, such as closed-source software. In other software projects that do not have complete maintenance records, especially some open-source software, there are no direct data for maintenance effort, which precludes the establishment of a maintenance effort model. In this paper, we report a series of studies aimed at presenting a method for indirectly predicting the maintenance effort of open-source software. This report covers two parts of our research. First, we examine the maintenance data from NASA SEL closed-source software projects and identify some software measures that can be used to indirectly represent maintenance effort. Second, based on the findings in the first part, we analyze 121 recent versions of Linux, and use linear regression to construct two indirect maintenance effort models for the Linux project. Our study demonstrates the applicability of this approach to indirectly predicting the maintenance effort and improving the software maintenance process.

In the context of a field investigation of these risks, several potential scenarios of OSS risk to organizations were identified, with two of them appearing as primary. The first primary scenario is the potential loss of control over revenue generating proprietary software when OSS source code and proprietary software source code are mixed together in one primary software works. The second primary risk scenario is the potential loss of control over software products or services offered within an organization due to legal disputes about intellectual property (IP).

This paper inductively derives a framework for understanding participation from the perspective of the individual software developer based on data from two software communities with different governance structures. In both communities, a need for software-related improvements drives initial participation. The majority of participants leave the community once their needs are met, however, a small subset remains involved. For this set of developers, motives evolve over time and participation becomes a hobby. These hobbyists are critical to the long-term viability of the software code: They take on tasks that might otherwise go undone and work to maintain the simplicity and modularity of the code. Governance structures affect this evolution of motives. Implications for firms interested in implementing hybrid strategies designed to combine the advantages of open source software development with proprietary ownership and control are discussed.","2006-07","2025-05-05 17:01:50","2025-05-05 17:01:50","","1000-1014","","7","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Motivation; Studies; Open source; Participation; Software; Open-source software; Product development; Governance; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Software Projects; Management science; Innovations; 2600:Management science/operations research; Inventors; Open; Viability; Business And Economics–Labor And Industrial Relations","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since software development is a creative task, the motivation of open source programmers can be compared to individuals in creative industries (Caves 2002). This paper summarizes the important trends in the research on motivation in open source and identifies variables that should be included in future research. Specifically, the current literature favors a taxonomy that considers two components of motivation–intrinsic (e.g., fun, flow, learning, community) and extrinsic (e.g., financial rewards, improving future job prospects, signaling quality). I make a case for incorporating both elements in developing an integrative theory about developer motivation. Three elements are identified as being unique to FLOSS development-diversity of project structures, co-existence of companies and communities and co-existence of creative and commercial elements. The important empirical evidence on FLOSS developer motivation is presented and analyzed. Four factors are identified as important mitigating and moderating factors in the conversation surrounding developer motivation- financial incentives, nature of task, group size and group structure. The role of these factors on developer motivation is discussed.[PUBLICATION ABSTRACT]","2006","2025-05-05 17:01:50","2025-05-05 17:01:50","","17–39","","4","18","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Sociology; Motivation; Open source; Open-source software; Software development; Developer; Creative industries","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Special emphasis is placed on the legal ramifications of this alternative approach to business software development and a long, complex lawsuit that threatens to restructure the open source philosophy. It is not surprising that commercial software companies have attacked Linux and other open source software packages. A legal attack from a company called SCO could jeopardize the future of open source software, with users and potential users of open source software fearful of previously unasserted intellectual property lawsuits. On Mar 6, 2003, the SCO Group initiated a civil lawsuit again IBM, claiming damages that were later increased to $5 billion. The possibility that SCO could have some proprietary claim to Linux is negated by the free software community's willingness to rewrite any offending code. At this time, there is little reason for organizations using Linux and other open source programs to fear the results of the SCO litigation.","2006-08","2025-05-05 17:01:51","2025-05-05 17:01:51","","5–9","","3","15","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Open source; Computer science; Open-source software; Linux; Operating systems; Intellectual property; Software development; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; 9190:United States; Books; Personal computers; Litigation; 4330:Litigation; Damage claims; Lawsuit; United States–US; Computers–Computer Security","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This process is reviewed and illustrated with OsiriX, a fast DICOM viewer program for the Apple Macintosh. Materials and methods OsiriX is an oss for the Apple Macintosh under Mac OS X v10.4 or higher specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: multiplanar reconstruction, surface rendering, volume rendering and maximum Intensity projection. All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT). OsiriX was developed using the Apple Xcode development environment and Cocoa framework as both a DICOM PACS workstation for medical imaging and an image processing software package for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging. Results OsiriX is an open source program by Antoine Rosset, a radiologist and software developer, was designed specifically for the needs of advanced imaging modalities. The software program turns an Apple Macintosh into a DICOM PACS workstation for medical imaging and image processing. OsiriX is distributed free of charge under the GNU General Public License and its source code is available to anyone. This system illustrates how open software development for medical imaging tools can be successfully designed, implemented and disseminated. Conclusion oss development can provide useful cost effective tools tailored to specific needs and clinical tasks. The integrity and quality assurance of open software developed by a community of users does not follow the traditional conformance and certification required for commercial medical software programs. However, open software can lead to innovative solutions designed by users better suited for specific tasks.","2006-12","2025-05-05 17:01:51","2025-05-05 17:01:51","","187-196","","4","1","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results demonstrate the utility of FDA for uncovering and categorizing multiple distinct patterns of evolution in the complexity of OSS projects. These results are promising in that they demonstrate some patterns in which the complexity of software decreased as the software grew in size, a particularly novel result. The paper reports preliminary explorations of factors that may be associated with decreasing complexity patterns in these projects.

Each of these tools typically excels at one type of analysis, such as of microarrays, of metabolic networks and of predicted protein structure. A crucial challenge is to combine the capabilities of these (and other forthcoming) data resources and tools to create a data exploration and analysis environment that does justice to the variety and complexity of systems biology data sets. A solution to this problem should recognize that data types, formats and software in this high throughput age of biology are constantly changing. Results: In this paper we describe the Gaggle -a simple, open-source Java software environment that helps to solve the problem of software and database integration. Guided by the classic software engineering strategy of separation of concerns and a policy of semantic flexibility, it integrates existing popular programs and web resources into a user-friendly, easily-extended environment. We demonstrate that four simple data types (names, matrices, networks, and associative arrays) are sufficient to bring together diverse databases and software. We highlight some capabilities of the Gaggle with an exploration of Helicobacter pylori pathogenesis genes, in which we identify a putative ricin-like protein -a discovery made possible by simultaneous data exploration using a wide range of publicly available data and a variety of popular bioinformatics software tools. Conclusion: We have integrated diverse databases (for example, KEGG, BioCyc, String) and software (Cytoscape, DataMatrixViewer, R statistical environment, and TIGR Microarray Expression Viewer). Through this loose coupling of diverse software and databases the Gaggle enables simultaneous exploration of experimental data (mRNA and protein abundance, protein-protein and protein-DNA interactions), functional associations (operon, chromosomal proximity, phylogenetic pattern), metabolic pathways (KEGG) and Pubmed abstracts (STRING web resource), creating an exploratory environment useful to `web browser and spreadsheet biologists', to statistically savvy computational biologists, and those in between.

This paper develops a framework of the OSS community ideology (including specific norms, beliefs, and values) and a theoretical model to show how adherence to components of the ideology impacts effectiveness in OSS teams. The model is based on the idea that the tenets of the OSS ideology motivate behaviors that enhance cognitive trust and communication quality and encourage identification with the project team, which enhances affective trust. Trust and communication in turn impact OSS team effectiveness. The research considers two kinds of effectiveness in OSS teams: the attraction and retention of developer input and the generation of project outputs. Hypotheses regarding antecedents to each are developed. Hypotheses are tested using survey and objective data on OSS projects. Results support the main thesis that OSS team members' adherence to the tenets of the OSS community ideology impacts OSS team effectiveness and reveal that different components impact effectiveness in different ways. Of particular interest is the finding that adherence to some ideological components was beneficial to the effectiveness of the team in terms of attracting and retaining input, but detrimental to the output of the team.

We introduce the articles in this special issue of Management Science on open source software, and show how each contributes insights to one or more of these areas.","2006-07","2025-05-05 17:01:53","2025-05-05 17:01:53","","975-983","","7","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Innovation; Studies; Open source; Software; Open-source software; Product development; Research; Governance; Intellectual property; Organization; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Software Projects; Management science; Innovations; 2600:Management science/operations research; Open; Public good; Business And Economics–Labor And Industrial Relations","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose here is to examine the role and power of software in the economy and review the economic impacts of the trend to OSS on the software industry, largely from a European industrial and social perspective. The paper briefly traces the economic significance of the software industry and the dominance in packaged software of the large US publishers, the phenomena of natural monopolies building in software packages, and the need for different industry structure for Europe, as it exhibits a small to medium-sized enterprise (SME) and system integrator structure. It then examines the balancing affects of OSS. The paper also addresses the role that poor software plays in creating new costs or externalities for its users when it fails, contrasting the robustness of open source in defect repair. The paper finds that the way forward in economic terms for Europe may well be to follow and encourage OSS for reasons of creating a strong software industry and for a counterbalance to current monopolistic trends. The paper's findings emphasise the need for investment, education and encouragement in OSS, by both the public and private sectors, to build a strong knowledge-based society in Europe. The paper introduces the ideas of the basic economic mechanisms of volume sales of software as a good, with analysis of the industry impacts of confluence of the network effect coupled with the law of increasing returns with volume to drive monopolistic positions in the proprietary software package industry.","2006","2025-05-05 17:01:53","2025-05-05 17:01:53","","12–31","","3","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Productivity; Open source; Open-source software; Software packages; Communications; Economics; 5240:Software & systems; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Economic; Software industry; 9175:Western Europe; Network effect; Employees; Employment; Economic development; 1110:Economic conditions & forecasts; Consumer goods; Economic growth; Economic impact; Global economy; Rainforest; Rainforests; Sales; Tax revenues; United Kingdom–UK; Gross Domestic Product–GDP","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because of the General Public License's dependence on copyright law, the deployment of FLOSS allows compliance with the Trade Related Aspects of Intellectual Property Rights (TRIPs) agreement, while at the same time facilitating the development of a local software 'community'.

The objective: to explore the evolution of a long-lived open source project with the intention of learning how code evolution has progressed over time. This investigation provides a case study of Nethack, an enormously popular open source game that has been in development for more than a decade. The Goal Question Metric approach was employed to derive measurement goals for the evaluation of open source software (OSS) evolution in Nethack. According to Lehman's laws, the incremental growth size of successive releases tends to decline during the active life of an evolving program. Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased. These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased. These findings raise questions concerning the evolution of other OSS applications.","2006","2025-05-05 17:01:54","2025-05-05 17:01:54","","47–58","","NA","NA","","","","SEW '06","","","","","","English","","","","","","","Backup Publisher: NASA Software Engn Lab; NASA Goddard Space Flight Ctr, Informat Syst\n Div; IEEE Comp Soc, TCSE ISBN: 0769526241 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

New so-called third generation (3G) or triple play services can be delivered to the market by means of using these architectures as well as respective IT support systems. Furthermore, various market players, stakeholders or alliances will come up at the telecommunications arena. The paper will systematic ally consider all these subject matters and elaborate that the use of New Generation Systems and Software (NGOSS) principles will leverage the OSS/BSS as well as IMS/SDP promise. In other words, to provide efficiently IMS/SDP based services requires an “IMS/SDP ready” OSS/BSS. There will be lots of well-known as well as quite a few new features to be provided by such an OSS/BSS. One example is that an “IMS/SDP ready” OSS/BSS does not only provide all the existing services very quickly.. it must also be able to support the design and creation of new types of services including new types of network/IT resources which allow these new kinds of services at all. This will impact the whole IMS/SDP as well as OSS/BSS environment, beginning with the Service Creation Environment (SCE) up to the extension of the Inventory Management System as the heart of the operational processes. However, the use of such an OSS/BSS in concert with the IMS/SDP will play a key role in allowing the operator or service provider to reduce Operational Expenditure while at the same time, delivering the efficiencies needed to speed up both the service and infrastructure provisioning processes. A system integrator's potential contribution in concert with state-of-the-art IT architectures such as Enterprise Application Integration (EAI), Service Oriented Architectures (SOA) and Workflow Management in delivering, a project driven solution are also described by this paper.","2006","2025-05-05 17:01:54","2025-05-05 17:01:54","","277-284","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-4244-0952-5 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

MGM takes into account several dimensions of complexity: size, structural complexity and coupling. Results show that maintainers of the eight open source systems studied tend, in general, to prioritize their anti-regressive work in line with the predictions given by our MGM, even though, divergences also exist.

To achieve that, the proposed tool has several options for signal processing and visualization, integrated into various tabs, pull down option menus, a fast access toolbar, and selectable graphical areas where the user can show the raw data, and the processed data. Furthermore, the proposed tool has an online user manual, made using multimedia techniques, describing its operation in details.

Their low budget characteristics make the vertical applications these users need natural targets for free/open source software (F/OSS) development efforts. The lack of technological challenges however, does not motivate experienced programmers to specify, code and test verticals. We are thus left with a problem of developing verticals which do not attract ROSS volunteers and whose end-users are not even able to specify them (they are IT naive) nor pay for professional help to do the job for them. This paper proposes a solution to such a problem. The solution is organized in the form of a university level F/OSS vertical development contest, which involves computer science professors as project leaders and students as “volunteered” programmers. Quality of the produced software is guaranteed by means of contest infrastructure, services, support kits which bring vertical seed code, coding and documentation standards and code reviews by the contest steering committee members. One such contest is being carried out in Brazil with the engagement of 5 universities to gain experience and evaluate contest risks, effectiveness and running processes. Results so far are encouraging having produced an already useful city government application. Results also indicated required adjustments in the technical details and procedures but also high levels of professor and student motivation. A nation-wide contest to produce more verticals for small city governments is scheduled to happen next.","2007","2025-05-05 17:01:55","2025-05-05 17:01:55","","197-204","","1-2","4","","","","Information and Communication Technologies and the Knowledge Economy","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-58603-801-4 Place: NA Publisher: NA","","","","NA","","Cunningham, P.; Cunningham, M.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The quantitation problem is mathematically formulated as a separable nonlinear least-squares fitting problem, which is numerically solved using a modified variable-projection procedure. A macromolecular baseline is incorporated into the fit via nonparametric modelling, efficiently implemented using penalized splines.

The pipeline can be accessed through user-friendly web interfaces at http://hpc.icrisat.cgiar.org/PBSWeb and is available on request for academic use.

Furthermore, teachers can have full control of what students do, since all operations are registered in a database which helps them to evaluate the students. Ciclope proposes a modular structure based on software components that are easy to install, configure, and extend according to teachers' needs. So far, various Web labs have been built to carry out practical assignments in astronomy, automatic control, chemistry, image processing, robotics, and real-time operating systems. The software, documentation, and content developed in this project are free, under GNU (a recursive acronym meaning GNU is Not UNIX) licenses, and as in all free projects, the authors welcome all collaboration from the educational community.","2007-11","2025-05-05 17:01:57","2025-05-05 17:01:57","","352-359","","4","50","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the current strategies deployed by law enforcement to combat cybercrime have proven ineffective. Borne out of traditional notions of criminal behavior, these strategies and tactics are often ill-suited to prevent or punish cybercrime, which often defies the traditional notions of criminal behavior bounded by the corporeal world such as scale and proximity. This Comment argues that a more effective methodology in the fight against cybercrime is to develop a model of community policing, in which the power to deter and prevent cybercrime is divested into the hands of individual computer users. One such strategy for achieving effective community policing against cybercrime is through the increased use of open-source soft-ware, software in which users are given access to the underlying source code and may make modifications to that source code in order to ameliorate vulnerabilities that may enable cybercrime. This Comment looks at the development of traditional community policing strategies and argues that the increased use of open source software-spurned by greater involvement by government and corporations-may be a more effective technique in the fight against cybercrime.","2007","2025-05-05 17:01:57","2025-05-05 17:01:57","","601-629","","2","97","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computer security; Police; Open-source software; Identity theft; Internet; Criminals; Cybercrime; Technological change; Freeware; Government subsidies; Vulnerability; Community policing; Computer viruses; Crime; Criminology And Law Enforcement; Neighborhood watch programs","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Lett., 72 ( 2005) 541), de Menezes and co-workers have shown how to separate internal dynamics from external fluctuations by capturing the simultaneous activity of many system's components. In spite of software development being a planned activity, the analysis of fluctuations reveals how external driving forces can be only observed at weekly and higher time scales. Hourly and higher change frequencies mostly relate to internal maintenance activities. There is a crossover from endogenous to exogenous activity depending on the average number of. le changes. This new evidence suggests that software development is a non-homogeneous design activity where stronger efforts focus in a few project files. The crossover can be explained with a Langevin equation associated to the cascading process, where changes to any. le trigger additional changes to its neighbours in the software network. In addition, analysis of fluctuations enables us to detect whether a software system can be decomposed into several subsystems with different development dynamics.

In 2005, several university libraries, university college libraries and other research libraries met and discussed a joint effort to create institutional archives. The meeting resulted in the Pepia project with BIBSYS as a software partner. The project group decided to use the open source system DSpace as a software platform. A standard DSpace installation runs on a Tomcat servlet container. BIBSYS does not use this container, and we therefore needed to configure DSpace to get it to run successfully on our server. In addition we had some problems with integrating the DSpace development structure with our integrated development environment. Further we needed to create a new build process that effectively could build more than 30 applications from one source code. These changes were quite time consuming, but they were necessary so that we could have an efficient work environment. Out of the box DSpace has many of the functionalities that an institutional archive requires. In spite of this we needed to alter some of the functionality, especially the user management system. DSpace is a complex system, but with the active community we could get the help we needed. BIBSYS Brage, the result of the Pepia project, was launched as a beta version in December 2006. We look forward to develop BIBSYS Brage further, and are confidant that it will become a great system for the consortium.","2007-12","2025-05-05 17:01:58","2025-05-05 17:01:58","","NA","","19","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: C ADOLF FLORENSA S-N, BARCELONA, 08028, SPAIN Publisher: UNIV BARCELONA, SERVEI PUBLICACIONS","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The famous phrase ""Tragedy of the Commons"" describes a situation where a natural resource commons, such as a pasture, or a water supply, gets depleted because of overuse. The tragedy in FLOSS commons is distinctly different – it occurs when collective action ceases before a software product is produced or reaches its full potential. This paper builds on previous work about defining success in FLOSS projects by taking a collective action perspective. We first report the results of interviews with FLOSS developers regarding our ideas about success and failure in FLOSS projects. Building on those interviews and previous work, we then describe our criteria for defining success/tragedy in FLOSS commons.

As an example, software used to determine whether a user has appropriate security clearance might be scattered throughout the many modules, which require this check. Utilising AOP, “aspects” are “woven” into the software either in a “static” method, during compilation, or a “dynamic” method while the program is executing. The “join points” in a program are the points where these aspects are applied. The “aspect” code is written once and “woven” in to the modules at join points. Typical aspects involve logging changes to a database and monitoring memory usage. Our focus is on aspects related to security and intrusion incident detection. Dynamic weaving allows aspects to be woven in and out as the program is executing. However the base code often must be compiled with additional “syntactic sugar” - additions that are required for the later connection of dynamic aspects. This paper presents a new technique to enable dynamically loaded security modules to be added into existing C/C++ code on the fly while the program is executing. Our tool is a Run-Time Event Monitoring System called “dynamicHook”, implemented on a standard Linux platform using existing Linux tools, which tests each potential join point for the required activation of advice. Our system does not need to modify the executable files, but instead we compile in special “linkage” between the base code and potential aspects which are then called as dynamically linked routines located in shared libraries. Our scheme does not require any new syntax or language extensions or rely on code transformations; we thus use it for adding intrusion detection methodologies to pre-existing off-the-shelf open source software.","2007","2025-05-05 17:02:00","2025-05-05 17:02:00","","147-154","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-905305-40-7 Place: NA Publisher: NA","","","","NA","","Armistead, L.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This shift is not only redefining the software industry but also the way we teach and learn in our software engineering (SE) courses. But for many universities F/OSS is seen as an optional low cost technology to support the IT infrastructure and administrational duties. Few see F/OSS as an opportunity for students to learn the SE concepts and skills we teach. Furthermore, it is still an open question as to whether the F/OSS methodology can be effectively used to teach SE courses within the formally structured curriculum in most universities. This paper discusses F/OSS projects as bazaars of learning that offer a meaningful learning context. The discussion is centered on a pilot study in which students were involved in software testing in F/OSS projects. We present the teaching and learning framework we used in the pilot study and report on our experiences, lessons learned, and some practical problems we encountered. Our grading and evaluation approach show that the students did relatively well as bug hunters and reporters. Results from two online surveys indicate that students are motivated in participating in software testing in the bazaar, and they are willing to participate in project activities long after their graduation. The study reveals one possible way SE educators can teach and integrate F/OSS into their formal curricular structure.

It is not until this method is examined more closely that its many advantages can be realised. The method can, however, seem very disorgamsed especially when compared with traditional proprietary development styles. A key difference between these two development approaches lies in the management of projects, and perhaps as a consequence, in the level of formality in the community environment. This paper presents the results of empirical survey research investigating FOSS community participants' views on the level of formality in FOSS, and the way in which this affects both development and support provision activities.

OSS models are congenial for both private companies and public administrations since they provide software users and suppliers with highly responsive and innovative development models which are likely to reduce costs and to provide additional autonomy within critical technological domains. OSS are characterized by the distribution of source code to any developer interested in contributing to the provision of the code. License terms allow a developer to make unlimited copies of the source code which can be modified indefinitely by developers to fulfil particular needs. Each developer is then free to distribute her work and exploit it commercially depending on license terms. The U.S. Department of Defense (DoD) is currently introducing Open Source Software (OSS) development models through its Open Technology Development (OTD) project (Herz et al. 2006). OSS adoption is becoming popular for military purposes. Indeed, the digital transformation of the U.S. military has generated a strong need for new modes of software management. In this context, the OTD project tends to set up an innovative model for software acquisition, maintenance, updating, and renewing. Focusing on the adoption of Military Open Source Software (MOSS) models by the U.S. Department of Defense (DoD), this article suggests that the open nature of OSS development platforms induces significant organizational changes related to the acquisition, transformation and creation of a variety of OSS core capabilities. Furthermore, we suggest that the U.S. military organizations should perceive modularity in software architecture as a means to establish effective modes of knowledge management and innovation. Building on the distinction between architectural and component knowledge, we find that modular source code structuring facilitates the division, distribution and coordination of both architectural knowledge and component knowledge within heterogeneous OSS developers' communities.","2007","2025-05-05 17:02:01","2025-05-05 17:02:01","","53-59","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-905305-61-2 Place: NA Publisher: NA","","","","NA","","Remenyi, D.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the following practices fundamental to projects and processes in software engineering are examined from an OSS perspective: project management; process, workflows, and collaborative activities; modeling and specification; deployment of standards; documentation; and quality assurance and evaluation. Based on a pragmatic framework, the prospects of integrating OSS in a traditional software engineering curriculum are outlined and concerns in realizing them are given. In doing so, the cases of the adoption of OSS process model, use of OSS as a Computer Aided Software Engineering (CASE) tool, OSS as a standalone sub-system, and open source code reuse are considered. We present some of the trade-offs that could help educators in decision making towards the use of the OSS environment in software engineering pedagogical contexts.

Using a longitudinal case study, we discuss in depth the deployment process for two OSS applications - the desktop application suite whose deployment was unsuccessful ultimately, and the email application which was successfully deployed. To our knowledge, this is the first such in-depth study into successful and unsuccessful OSS implementation. Given that our study was a longitudinal one in a single organization, we can control a number of potentially important influencing elements which would not be possible if multiple organizations were involved.

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition.

There are many ways to use OSS in the enterprise, ranging from a few components to single applications, suites of related applications, and complete enterprise solutions.With such a diversity of applications, OSS use is even more attractive, yet it is not a trivial undertaking. The logistics of moving to OSS need not be daunting, however, if the organization considers the entire modernization plan, considers what various application types require, and does not undertake too much conversion at once.","2007-08","2025-05-05 17:02:03","2025-05-05 17:02:03","","28–33","","4","9","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Open source; Software engineering; Software; Open-source software; Linux; Documentation; Software development; Software quality; Interoperability; 5240:Software & systems; Public domain; 2500:Organizational behavior; Innovations; Organization theory; Engineering; 9190:United States; 2310:Planning; Open; Corporate planning; Modernization; Software modernization; United States–US","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweight open source systems for patient and sample information management. Results: We present a web-based tool for submission, management and retrieval of sample and research subject data. The system secures confidentiality by separating anonymized sample information from individuals' records. It is simple and generic, and can be customised for various biomedical studies. Information can be both entered and accessed using the same web interface. User groups and their privileges can be defined. The system is open-source and is supplied with an on-line tutorial and necessary documentation. It has proven to be successful in a large international collaborative project. Conclusion: The presented system closes the gap between the need and the availability of lightweight software solutions for managing information in biomedical studies involving human research subjects.","2007-02-09","2025-05-05 17:02:03","2025-05-05 17:02:03","","NA","","NA","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we examine the process of patch reviews as a proxy for the extent of code-review in F/OSS projects. While existing descriptions of patch review processes are mostly narrative and based on individual experiences, we systematically analyze the email archives of five F/OSS projects to characterize this process. While doing so, we make a distinction between contributions (patches or review comments) by core members and casual contributors to grasp the role of core members in this process. Our results show that while the patch review processes are not exactly identical across various F/OSS projects, the core members across all projects play the vital role of gate-keepers to ensure a high level of review for submitted patches.","2007","2025-05-05 17:02:04","2025-05-05 17:02:04","","166c","","NA","NA","","","","HICSS '07","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 0769527558 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Building on information from an extensive dataset of secondary sources and 30 in-depth interviews, I show that de novo entrants have emerged in conjunction with a changing institutional infrastructure and a more pragmatic attitude toward firms that focus on technological benefits rather than ideology. To understand how these firms try to harness the work of these communities, I use the empirical data to derive a 2*2 matrix of different approaches. The X axis reflects whether or not the firms initiated a new community or relied on communities founded by peers, whereas the Y axis represents the degree of participation of the firm in the community. This taxonomy illustrates how de novo entrants are initiating new forms of communities or joining communities established by peers. This suggests that while many of the central pillars of FOSS remains, de novo entrants have emerged to find new ways of making business resulting in various implications for firm strategies and knowledge disclosure.

On the negative side, this increasing dependence on computers has resulted in research that has become increasingly difficult to replicate. In this paper, we propose some basic standards to improve the production and reporting of computational results in economics for the purpose of accuracy and reproducibility. In particular, we make recommendations on four aspects of the process: computational practice, published reporting, supporting documentation, and visualization. Also, we reflect on current developments in the practice of computing and visualization, such as integrated dynamic electronic documents, distributed computing systems, open source software, and their potential usefulness in making computational and empirical research in economics more easily reproducible.

In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere. I argue that these competing views are consequential, for they link technical artifacts and political agents in practice, by way of aspirations, obligations, and forms of authority. Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.","2007-05","2025-05-05 17:02:05","2025-05-05 17:02:05","","211-235","","2","93","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD","","","","open source software; artifact; Bruno Latour; public sphere theory; socio-technical deliberation; free\n","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

This quality degradation effect, called entropy, is a cause for higher maintenance costs. In the Open Source context, the quality of code is a fundamental tenet of open software developers. As a consequence, the quality degradation principle measured by entropy cannot be assumed to be valid. The goal of the paper is to analyze the entropy of Open Source applications by measuring the evolution of maintenance costs over time. Analyses are based on cost data collected from a sample of 1251 Open Source application versions, compared with the costs estimated with a traditional model for proprietary software. Findings indicate that Open Source applications are less subject to entropy, have lower maintenance costs and also a lower need for maintenance interventions aimed at restoring quality.

For this reason, this work aims to explore some of the effects of participation in a virtual brand community on consumer behaviour. Design/methodology/approach - The paper proposes the positive effects of participation in a virtual community on both consumer trust and loyalty to the product, brand or organisation around which the community is developed. In addition, it also proposes a positive effect of trust on consumer loyalty. After the validations of measurement scales, the hypotheses are contrasted through structural modelling. Findings - The data, obtained through a web survey using members of several free software virtual communities, show that participation in the activities carried out in a virtual community may foster consumer trust and loyalty to the mutual interest of the community (the free software in this case). In addition, the study also found a positive and significant effect of consumer trust on loyalty. Research limitations/implications - Data were collected thanks to a web survey using Spanish-speaking subjects. Practical implications - The high costs every company has to face in order to get new customers make it increasingly necessary to reinforce the ties established with customers. In this respect, this study has shown that managers may foster consumer trust and loyalty by developing virtual brand communities and promoting consumers' participation in them. Originality/value - Most of the works that are focused on virtual communities have been conducted at the conceptual level. Thus, with the aim of moving on this topic, this study analyses empirically the effects of participation in a virtual brand community on consumer behaviour.","2007","2025-05-05 17:02:06","2025-05-05 17:02:06","","775-792","","6","31","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Communication; Social interaction; Community; Qualitative research; Studies; Virtual communities; Participation; Software; Consumer behavior; Group Dynamics; Consumers; Brand loyalty; Virtual community; Internet; Trust; Computer Mediated Communication; Social networks; Loyalty; Surveys & questionnaires; 9130:Experimental/theoretical; 7100:Market research; 5250:Telecommunications systems & Internet communications; Community Relations; Brand; Brand community; Community Involvement; Consumer behaviour; Customer retention; Electronic Mail; Information Sources; Literature Reviews; Virtual networks; Computers–Internet","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The conflict over the revision has been known only through published sources. A seal has remained over the dynamics between the two dozen members of the committee responsible for the revision of the New Testament. The official minute book yields nothing of the textual, grammatical, and translational debates nor of the voting patterns governing decisions.

Therefore, the aim of this study is to explore the factors that affect trust in OSS communities. The data is gathered by a survey aimed to Linux Kernel developers. Among other results it may be concluded that the most important factors affecting trust seem to be other developers' skills, reputation as well as the formal and informal practices.","2007","2025-05-05 17:02:07","2025-05-05 17:02:07","","223+","","NA","234","","","","International Federation for Information Processing","","","","","","English","","","","","","","Backup Publisher: IFIP WG2 13 ISBN: 978-0-387-72485-0 Place: 233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES Publisher: SPRINGER","","","","case study; survey; trust; OSS community; Linux Kernel","","Feller, J.; Fitzgerald, B.; Scacchi, W.; Sillitti, A.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there are numerous issues associated with OSS, including its influence on the total cost of ownership (TCO) and supportability and upgradeability risks. While savings from obtaining a free copy of the software can be significant, software accounts for an average of 10% of TCO, while the majority of the costs are associated with project staffing. OSS requires significant investment into staffing because it needs to be carefully selected, customized, and installed. In addition, global communities may gather and dissolve at their will, so guarantees of support, revision, and bug fixes are minimal. Yet companies can gain competitive advantage through an ability to customize software to address specific business issues and exercising control over development, revision schedules, and modifications. OSS is not a panacea from the rising software costs. Instead, it is a serious initiative that has benefits, disadvantages, and risks associated with it.","2007","2025-05-05 17:02:07","2025-05-05 17:02:07","","277-282","","NA","234","","","","INTERNATIONAL FEDERATION FOR INFORMATION PROCESSING","","","","","","NA","","","","","","","Backup Publisher: IFIP WG2 13 ISBN: 978-0-387-72485-0 Place: NA Publisher: NA","","","","NA","","Feller, J.; Fitzgerald, B.; Scacchi, W.; Sillitti, A.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Infrastructures and FLOSS software exhibit multiplicity: as objects they both change and stay the same. Whilst the implications of multiplicity with respect to infrastructure have been well-documented, with respect to FLOSS, they remain under-explored. Through examining how the DBE engaged new participants we were able to explore the nature of the FLOSS software object by asking the implied question: engagement with what? We draw on recent analysis by Law and Singleton to show how the innovative yet non-existent potentiality of the DBE was as significant to engagement as its steadily growing codebase.

Software distributions specify the dependencies needed to build and to run a given software application. We use this information to create a dependency graph of the applications contained in such a distribution. We explore the characteristics of this graph, and use it to define some metrics to quantify the dependencies (and dependents) of a given software application. We demonstrate that some applications that are invisible to the final user (such as libraries) are widely used by end-user applications.

We downloaded projects by topics data in five areas (Database, Internet, Software Development, Communications, and Games/Entertainment) from Flossmole's raw and summary data of the sourceforge repository. Time series analysis show the numbers of projects in the five topics are growing linearly. Further analysis supports our hypothesis that F/OSS development is moving “up the stack” from developer tools and infrastructure support to end-user applications such as Databases.

Universally accessible browsers require novel interaction modalities and additional functionalities, for which existing browsers tend to provide only partial solutions.

This enables browser access to a wide variety of open source and free software components. The main contribution of AMICO:WEB is in enabling the syntactic interoperability between Web extension mechanisms and a variety of integration mechanisms used by open source and free software components. It also bridges the semantic differences between the high-level world of Web XML-based APIs and the low-level APIs of the device-oriented world.We discuss the design decisions made during the development of AMICO:WEB in the context of Web accessibility, using two typical usage scenarios: one describing a disabled user using a mainstream Web browser with additional interaction modalities; another describing a non-disabled user browsing in a suboptimal interaction situation.","2007","2025-05-05 17:02:08","2025-05-05 17:02:08","","15–24","","NA","NA","","","","W4A '07","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 1595935908 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software; user interfaces; middleware; software platform; web accessibility","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Second, the first and last 50 emails for two top developers who have left the project are examined. The analysis shows promise in understanding why developers join and leave a project.

In case of considering the effect of the debugging process on an entire system in the development of a method of reliability assessment for the OSS, it is necessary to grasp the deeply-intertwined factors, such as programming path, size of each component, skill of fault reporter, and so on. In order to consider the effect of each software component on the reliability of an entire system, we propose a new approach to user-oriented software reliability assessment by creating a fusion of neural network and software reliability growth modeling. In this paper, we show application examples of component-oriented software reliability assessment based on neural network and software reliability growth modeling for the OSS.

Developers of Python are geographically distributed and work online asynchronously. The objective of our study is to understand and to model the dynamics of the OSS design process that takes place in mailing list exchanges. We develop a method to study distant and asynchronous collaborative design activity based on an analysis of quoting practices. We analyze and visualize three aspects of the online dynamics: social, thematic temporal, and design. We show that roles emerge during discussions according to the involvement and the position of the participants in the discussions and how they influence participation in the design discussions. In our analysis of the thematic temporal dynamics of discussion, we examine how themes of discussion emerge, diverge, and are refined over time. To understand the design dynamics, we perform a content analysis of messages exchanged between developers to reveal how the online discussions reflect the “work flow” of the project: it provides us with a picture of the collaborative design process in the OSS community. These combined results clarify how knowledge and artefacts are elaborated in this epistemic, exploration-oriented, OSS community. Finally, we outline the need to automate of our method to extend our results. The proposed automation could have implications for both researchers and participants in OSS communities.

From an evolutionary perspective, the picture is unclear - we still know relatively little about how, over time, changes tend to be applied by developers. Our conjecture is that an inheritance hierarchy will tend to grow ‘breadth-wise’ rather than ‘depth-wise’. This claim is made on the basis that developers will avoid extending depth in favour of breadth because of the inherent complexity of having to understand the functionality of superclasses. Thus the goal of our study is to investigate this empirically. We conduct an empirical study of seven Java Open-Source Systems (OSSs) over a series of releases to observe the nature and location of changes within the inheritance hierarchies. Results showed a strong tendency for classes to be added at levels one and two of the hierarchy (rather than anywhere else). Over 96% of classes added over the course of the versions of all systems were at level 1 or level 2. The results suggest that changes cluster in the shallow levels of a hierarchy; this is relevant for developers since it indicates where remedial activities such as refactoring should be focused.","2008","2025-05-05 17:02:09","2025-05-05 17:02:09","","269–278","","NA","NA","","","","ASWEC '08","","","","","","NA","","","","","","","Backup Publisher: Australian Comp Soc; Engineers Australia; Curtin Univ Technol; L3 Commun\n Nautronix; Murdoch Univ; ECU; Thales; Motorola; Davies Collison Cave;\n Project Performance Int; Object Consulting; SYSTEC ISBN: 9780769531007 Place: USA Publisher: IEEE Computer Society","","","","Evolution; Inheritance.","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By analyzing how social networks of developers evolve over time while building OSS products, we can gain knowledge and experience to improve the effectiveness and efficiency of resource management and distribution in future OSS projects. To this end, we studied the evolution of the developer communities using a suite of OSS products developed under the KOffice project.

Since separated sounds suffer from spectral distortion due to separation, HARK generates a temporal-frequency map of reliability called “missing feature mask”, for features of separated sounds. Then separated sounds are recognized by the Missing-Feature Theory (MFT) based ASR with missing feature masks. HARK is implemented on the middleware called “FlowDesigner” to share intermediate audio data, which provides real-time processing.

The traditional market failure argument suggests that innovation is characterized by high investment and low copy cost, and firms have difficulty in internalizing the fruits of their innovative effort. Thus, technology firms are seeking more patents, expanding their scope and overhauling their business models around intellectual property. Yet paradoxically, with the progress and development of information technology, open source software (OSS) plays an important role in expanding enterprise informatization. For example, Linux is developed quickly by this open way. Some firms have found the ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is one example. In this article, the author introduces a model of OSS based on its network effects to understand how the enterprises decide their activities in this open market competition. This article describes the inherent reasons of open source movement from the view of the oligopoly structure. At the same time, this article analyses the effect of leader enterprise and follower enterprise on market structure and the different activities of these enterprises after the source has been opened. Finally, we make suggestions that companies at the leading edge are often in such a strong position that they do need the support of down-streams companies to broaden their technologies successfully and to decrease their risks in order to leverage the value of the technological portfolio. On the other hand, this article suggests that follower enterprises have incentive to take part in the development of open-source software only when the market has grown up.","2008","2025-05-05 17:02:10","2025-05-05 17:02:10","","669+","","NA","254","","","","International Federation for Information Processing","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-0-387-75901-2 Place: 233 SPRING STREET, NEW YORK, NY 10013, UNITED STATES Publisher: SPRINGER","","","","open source software; enterprise normalization; OSS model","","Xu, L.

However, as argued in this paper, the process of this vertical disintegration may be affected by high investments to software interface implementation and maintenance. Should the required efforts be large, the threshold for entering the market increases, thereby hampering the vertical disintegration process. This study examines the impact of the interface implementation efforts on the vertical market evolution in the case of the so-called operations support systems and business support systems (OSS/BSS) software, which are employed by the telecom operators in order to support their daily operations. The efforts are compared for two prototypical software vendors serving incumbent operators and new operators respectively. Total efforts are an order of magnitude larger in the former case. Furthermore, even if only latest network protocols are taken into account, the efforts are significantly larger in the former case, therefore requiring several times greater number of employees to implement them. Therefore, a conclusion is made that the OSS/BSS market is likely to polarize into the vertical submarket of large software vendors serving incumbent operators, and the submarket of small vendors serving young operators. The latter submarket, due to the lower entry threshold for new vendors is more likely to be vertically disintegrated.","2008","2025-05-05 17:02:10","2025-05-05 17:02:10","","80+","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Inst Syst & Technol Informat, Control & Commun; Workflow Management\n Coalit, Proc Thought Leadership; IICREST ISBN: 978-989-8111-52-4 Place: NA Publisher: NA","","","","NA","","Cordeiro, J.; Shishkov, B.; Ranchordas, A.; Helfert, M.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Understanding the structure of software systems can provide useful insights into software engineering efforts and can potentially help the development of complex system models applicable to other domains. In this paper, we analyze one of the most popular open-source Linux meta packages/distributions called the Gentoo Linux. In our analysis, we model software packages as nodes and dependencies among them as edges. Our empirical results show that the resulting Gentoo network cannot be easily explained by existing complex network models. This in turn motivates our research in developing two new network growth models in which a new node is connected to an old node with the probability that depends not only on the degree but also on the “age” of the old node. Through computational and empirical studies, we demonstrate that our models have better explanatory power than the existing ones. In an effort to further explore the properties of these new models, we also present some related analytical results. (C) 2008 Elsevier B.V.

Design/methodology/approach - The proposal is based on SMIL as composition language. Particularly, the paper reuses and customizes the SMIL template used by INRIA on their technical presentations. It also proposes a set of free tools to produce presentation content and design focusing on RealPlayer as delivery client. The integration in this e-learning platform of multimedia compositions developed following the proposed technique is also presented. Findings - Technological support to learning and teaching has become widespread due to computers and internet ubiquity. Particularly e-learning platforms permit the any-time-and-any-place distribution of interactive multimedia learning materials. There are commercial tools available to author this kind of content, usually based on proprietary formats. This option has some drawbacks like license cost and software company dependency. To use open data standards and free software is an alternative without these inconveniences but available authoring tools are commonly less productive. This shortcoming is certainly important to non-technical authors and it could be solved by open source collaboration.

A popular example of open innovation has been open source software (OSS). The key issues facing organizational decision makers considering OSS strategies is, how does the firm create value for the customer while simultaneously extracting value for itself? However, the adoption of OSS as part of an open innovation strategy is a recent phenomenon and many unanswered questions remain. Taking the viewpoint of seven IS/IT decision makers in European firms, this paper reveals how decision makers considered aspects of value creation, capture, and networking in making decisions on adopting open source software. The findings reveal that while decision makers look to open innovation for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.","2008","2025-05-05 17:02:12","2025-05-05 17:02:12","","229+","","NA","287","","","","International Federation for Information Processing","","","","","","NA","","","","","","","Backup Publisher: IFIP TC8 WG8 6; Spanish Minist Sci & Innovat; IBM; Ericsson; Madrid\n City Council; Telefon Invest & Desarrollo; Univ Politen Madrid ISBN: 978-0-387-87502-6 Place: NA Publisher: NA","","","","NA","","Leon, G.; Bernardos, A.

Notably, e-Learning applications which have now become central to the learning process may be developed using proprietary programming tools and the process of acquiring and using them to develop large software application is not only complex but require a huge sum of money. A viable alternative is to utilize the open source software platform that allows software engineers and institutions the right to reuse, study, distribute and localize to satisfy user's requirements.

However, only simple models, e.g. stage-damage curves, have been used frequently. Further, the reliability of flood loss and risk estimates is fairly unknown, since flood loss models are scarcely validated. In the aftermath of flooding in August 2002 large data sets of flood losses were collected at affected properties in Germany. These data were used to derive multi-factorial loss models. This paper presents FLEMOps - the Flood Loss Estimation Model for the private sector, which estimates direct monetary flood losses of residential buildings and household contents considering water level, building type and building quality. In an additional model stage (FLEMOps+), the effects of private precautionary measures as well as of the contamination of the floodwater can be quantified. Together with census data and land use information the model is adapted for applications on the meso-scale. Further, different data sets of repair costs for single buildings and in whole municipalities were used to validate loss estimates on the micro- as well as on the meso-scale. First results show that the model FLEMOps+ outperforms simple stage-damage-functions.","2008","2025-05-05 17:02:12","2025-05-05 17:02:12","","315+","","NA","118","","","","WIT Transactions on Ecology and the Environment","","","","","","NA","","","","","","","Backup Publisher: Univ Wolverhampton; Wessex Inst Technol; WIT Transact Ecol & Environm;\n Royal Inst Chartered Surveyors; Chartered Inst Loss Adjusters ISBN: 978-1-84564-132-0 Place: NA Publisher: NA","","","","NA","","Proverbs, D.; Brebbia, C.

This approach re-scales March's (1991) framework and applies it to characterize the ""innovation system"" of a ""distributed organization"" of interacting agents in a virtual collaboration environment, rather than to innovation within a firm. March (1991) views the process of innovation at the organizational level as the coupling of sub-processes of exploration and exploitation. Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.","2008","2025-05-05 17:02:12","2025-05-05 17:02:12","","449–462","","5","16","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Productivity; Software engineering; Open-source software; Success; Cybersecurity; Software development; Software quality; 5240:Software & systems; Public domain; Software Projects; 9130:Experimental/theoretical; 5140:Security management; Efficiency; Debugging; Data envelopment analysis; Engineering economics; Envelopment; Linear programming; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, rising the GINI coefficient as a measure of inequality within the developer group.","2008-06","2025-05-05 17:02:13","2025-05-05 17:02:13","","31-57","","2","19","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Open source; Software; Software development; Product design; Impact analysis; Public domain; Source code; Gini coefficient; Repositories; Computers–Data Base Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With this unprecedented pace of innovation, comes new obligations. In this article the authors discuss the areas of governance, education, and tools which together constitute the base capabilities required for the effective enterprise adoption of F/LOSS technology and principles.

Next we examine the role of these technologies in bridging the digital divide along three complementary dimensions. First, we show that both affordable technology and sound policy are necessary for digital inclusion. Second, we look at how these two technologies are extended, integrated, and customized in information and communication technology (ICT) solutions that are both creative and effective. Third, we describe how the hardware and software in networked systems have been tailored to support applications that are as diverse as the people using them.

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways. This may be due primarily to the fact that open source ultimately produces greater value on both the use and production sides, implying an impact on welfare. This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market. To support this, a market concentration index, the HHI index, is tested over the case of web servers. As a result the study reveals that under the appropriate conditions, OSS call have a positive impact on welfare.","2008","2025-05-05 17:02:14","2025-05-05 17:02:14","","1-26","","NA","NA","","","","Social Issues Justice and Status","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-60741-222-9 Place: 400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA Publisher: NOVA SCIENCE PUBLISHERS, INC","","","","NA","","Stroud, B.

Qualitative data were collected over a four year period using a virtual ethnography in a study of free and open source software development and, in particular, a study of a free software community, GNUenterprise, located at www.gnuenterprise.org, which has the goal of developing a free enterprise resource planning software system. It is concluded that the ideology of the free software movement continues to be one of the factors which mobilize people to contribute to free and open source software development. This movement represents a new type of computerization movement which promotes the investment of time in learning a new software development process instead of investment of money in the acquisition and use of new technology. The research findings are limited by a detailed study of only one free software development project. This paper is of significance to software developers and managers of firms who wish to incorporate free and open source software into their companies. This research presents an original conceptual diagram and framework for how computerization movements have emerged into an occupational community.

The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. Design/methodology/approach - The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. Findings - The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain. Last, but not least, it blurs the boundary between development and use, since the developer remains the key user. Research limitations/implications - The paper addresses the implications for future research in the area. Practical implications - The paper addresses implications for practitioners directly involved in innovation and product development. Originality/value - This paper develops a conceptual framework for understanding product development based on non-proprietary knowledge, which cannot be adequately accounted for by traditional corporate innovation theory alone.","2008","2025-05-05 17:02:15","2025-05-05 17:02:15","","142+","","1","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD","","","","Innovation; Communication technologies; Internet; Open systems; Resource\n management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine the two peer review techniques used by the successful, mature Apache server project: review-then-commit and commit-then-review. Using archival records of email discussion and version control repositories, we construct a series of metrics that produces measures similar to those used in traditional inspection experiments. Specifically, we measure the frequency of review, the level of participation in reviews, the size of the artifact under review, the calendar time to perform a review, and the number of reviews that find defects.

By detailed studies of mailing lists of two popular OSS libraries (Lucene-Java and Apache Commons), this paper attempts to understand the effectiveness of mailing list-based peer support system.

The distance between the target and needle tip location was measured based on confirmatory scans which gave an average of 3.56 mm. In the second study, three foam nodules were placed at different depths in a gelatin phantom. Ten targeting passes were attempted in each of the three depths. Final distances between the target and needle tip were measured which gave an average of 3.00 mm.

The standardized seasonal rainfall Shows all autumn trend that approximates the annual trend With amplitude of live years, while rainfall during the winter declines and inclines during above the long-term average during spring. Concurrently, sodium, sulfate and chloride soil concentrations increased rapidly in the late 1990s, together with increases ill the very fine sand fraction, which reflects the active erosion and deposition processes associated with recent human interference. There is a general process of recharging plant species diversity (long-term records; 122 perennials and 104 annuals) in the late 1990s following a sizeable decline; 26 perennials with declining density and spatial occupation call be considered at threat. Some of these species are transient and show a three-year cycle of species replacement (turnover when related to added species). The change ill the diversity of perennial species is allied to changes in rainfall, temperature and wind speed related to the climatic, salinity, bicarbonate, calcium, and Sulfate of the edaphic variables. This also applies to endangered species, where especially air temperature and Soil sulfates are the most determinant driving factors.

To begin with, the article defines the term “source code” in reference to software” and it also explains the terms “open source” and “free software.” Moreover, it introduces the definition of Free/Open-Source Software (FOSS). In the following part of the article, Konat offers a microeconomic analysis of “strategic forking” to determine the motives guiding software engineers taking part in FOSS projects. The problem is discussed from the perspective of the theory of public goods, the demand-side approach to innovation, and other theories concerned with issues such as “hackers' ethic” and “ego boosting.” Konat pays special attention to describing the “strategic forking” phenomenon with the use of classical microeconomic and enterprise theory tools developed by researchers Jean Tirole and Josh Lerner. The author follows up with a comprehensive analysis of strategic forking as a key to explaining a fundamental discrepancy in the assessment of the motives that guide programmers taking part in the development of open-source software. The analysis focuses on the definition of strategic forking, the conditions determining this trend and its direct causes. Konat also looks at the implications of strategic forking and the factors due to which this approach has not become more widespread around the world. The article closes with a review of issues that require further analysis, according to Konat. These include the issue of software distribution.","2008-10","2025-05-05 17:02:17","2025-05-05 17:02:17","","23-43","","10","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A theoretical rationale for the method is then offered and several unique features detailed. The evolution of the methodology in practice is described and salient lessons highlighted. In addition to gathering a large volume of rich data as intended, early phases of the implementation of this method produced a number of unanticipated but significant findings.

This chapter uses coordination theory to analyze the bug fixing processes in the proprietary operating system development group of a large minicomputer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel. Three approaches to identifying dependencies and coordination mechanisms are presented. Mechanisms analyzed include those for task assignment, resource sharing, and managing dependencies between modules of source code. The proprietary development organization assigned problem reports to engineers based on the module that appeared to be in error, because engineers only worked on particular modules. Alternative task assignment mechanisms include assignment to engineers based on workload or voluntary assignment, as in Linux. In the proprietary process, modules of source code were not shared but, rather, were “owned” by one engineer, thus reducing the need for coordination. In Linux, where multiple developers can work on the same modules, alternative resource sharing mechanisms have been developed to manage source code. Finally, the proprietary developers managed dependencies between modules informally, relying on their personal knowledge of which other engineers used their code. The Linux process allows developers to change code in multiple modules, but emphasizes modularity to reduce the need to do so. By helping in the identification of dependencies in the bug fixing processes, drawing upon coordination theory streamlines bug fixing activities of a large mini-computer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel.","2008","2025-05-05 17:02:18","2025-05-05 17:02:18","","69-99","","NA","9","","","","Advances in Management Information Systems","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-0-7656-1191-8 Place: NA Publisher: NA","","","","NA","","Grover, V.; Markus, M.

Unfortunately this goal has not been achieved mainly due to a lack of both tools and data management, as data must be gathered from different sources and in different formats. Compounding this problem is the fact that in some regions different water agencies are in charge of water supply as is the case in the Basin of Mexico, in which Mexico City and its Metropolitan Zone are located. The inhabitants of the Basin of Mexico, which comprises five different political entities and in which different agencies are in charge of water supply rely on the Basin's aquifer system as its main water supply source. However, a regional hydrogeological database in this area does not exist which is why the use of both a Relational Database Management System (RDMBS) and a Geographic Information System (GIS) is proposed in order to improve regional data management in the study area. Data stored in this new database, the Basin of Mexico Hydrogeological Database (BMHDB) comprise data on climatological, borehole and run-off variables, readily providing information for the development of hydrogeological models. A simple example is used to show how geostatistical analysis can be done using the data directly from the BMHDB. The structure of the BMHDB allows easy maintenance and updating, representing a valuable tool for the development of regional studies. (c) 2008 Elsevier Ltd.

This may result in an ideological-rather than pragmatic-decision. A recent study has shown that American organizations are quite pragmatic in their adoption decision. We argue that there may be circumstances in which there is more opportunity for ideological behavior. We therefore investigated the organizational adoption decision in Belgian organizations.

Consequently, these data are being discovered, gathered, analyzed, and used to support multidisciplinary research. However at present, no means exist for assembling these data under common access points and frameworks for comparative, longitudinal, and collaborative research across disciplines. Gathering and maintaining large F/OSS data collections reliably and making them usable present several research challenges. For example, current projects usually rely on direct access to, and mining of raw data from groups that generate it, and both of these methods require unique effort for each new corpus, or even for updating existing corpora.

Nevertheless, user acceptance towards this type of technology has received very little attention. For this reason, the main purpose of the current study is to identify the variables and factors that have a direct effect on individual attitude towards OSS adoption. Therefore, we have developed a technological acceptance model on behalf of the users towards a solution based on OSS. For this development, we have considered the technology acceptance model.

Focusing on the Python community, our study examines a “pushed-by-users” design proposal through the discussions occurring in two mailing-lists: one, user-oriented and the other, developer-oriented. To characterize the links between users and developers, we investigate the activities and references (knowledge sharing) performed by the contributors to these two mailing-lists. We found that the participation of users remains local to their community. However, several key participants act as boundary spanners between the user and the developer communities. This emerging role is characterized by cross-participation in parallel same-topic discussions in both mailing-lists, cohesion between cross-participants, the occupation of a central position in the social network linking users and developers, as well as active, distinctive and adapted contributions. The user championing the proposal acts as a key boundary spanner coordinating the process and using explicit linking strategies. We argue that OSS design may be considered as a form of “role emerging design”, i.e. design organized and pushed through emerging roles and through a balance between these roles. The OSS communities seem to provide a suitable socio-technical environment to enable such role emergence. (C) 2007 Elsevier Ltd.

Introducing new technologies requires a ""proof of concept"" process in order to decide on the profitability of further development. Using Open Source software solutions in the BL helped make this process quicker and more efficient.The BL has been developing its proprietary Computer Generated Forces (CGF) for approximately 10 years. This CGF is mainly intended for simulating ground entities and has various capabilities for autonomous movement. Over the years, as the visual systems have improved and due to the introduction of urban environments simulation, the need for realistic movement characteristics, especially human, became important. An in-house solution, developed by the CGF team, appeared to consume too much development effort and was not extendable enough. After analyzing the problem and reviewing various third-party solutions, the CGF team decided on using an Open Source (OS) library called OpenSteer.Until recently, ground vehicle simulations in the BL used a low fidelity non-physical movement mode, based on ground clamping. In 2006 the BL got involved in research areas related to Unmanned Ground Vehicles (UGVs) and human-robotics interactions. During early research stages it became clear that it would be necessary to simulate the UGV dynamics in higher fidelity than was done before. The development team decided to initiate the ""proof of concept"" process before full scale development. Therefore a quick solution for a high-fidelity vehicle simulation was searched for. After a brief review of third party solutions, an OS library, Open Dynamics Engine (ODE) was chosen. Developing a UGV simulation required an autonomous movement model which appeared to have similar characteristics to the one developed by the CGF team based on OpenSteer. Since OpenSteer was not originally intended for simulating rigid-body vehicles, the development team faced the challenge of integrating both products, OpenSteer and ODE. This paper will describe the steps taken in order to assimilate OS products in the BL simulation test-bed and lessons learned.","2008","2025-05-05 17:02:20","2025-05-05 17:02:20","","NA","","NA","NA","","","","SCSC '08","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: Vista, CA Publisher: Society for Modeling & Simulation International","","","","open source software; licenses; copyleft; BSD; CGF; feasibility study; GPL; ground vehicle modeling; IDF Battle Lab; movement modeling; ODE; OpenSteer; test-bed; wrappers","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study objective was to validate two complementary indicators, i.e., the OIDP (Oral Impacts on Daily Performances) and Oral Satisfaction 0-10 Scale (OSS), in two qualitatively different socio-demographic samples of the Spanish adult population, and to analyse the factors affecting both perspectives of well-being. Methods: A cross-sectional study was performed, recruiting a Validation Sample from randomly selected Health Centres in Granada (Spain), representing the general population (n = 253), and a Working Sample (n = 561) randomly selected from active Regional Government staff, i. e., representing the more privileged end of the socio-demographic spectrum of this reference population. All participants were examined according to WHO methodology and completed an inperson interview on their oral impacts and oral satisfaction using the OIDP and OSS 0-10 respectively. The reliability and validity of the two indicators were assessed. An alternative method of describing the causes of oral impacts is presented. Results: The reliability coefficient (Cronbach's alpha) of the OIDP was above the recommended 0.7 threshold in both Validation and Occupational samples (0.79 and 0.71 respectively). Test-retest analysis confirmed the external reliability of the OSS (Intraclass Correlation Coefficient, 0.89; p < 0.001) Some subjective factors (perceived need for dental treatment, complaints about mouth and intermediate impacts) were strongly associated with both indicators, supporting their construct and criterion validity. The main cause of oral impact was dental pain. Several socio-demographic, behavioural and clinical variables were identified as modulating factors. Conclusion: OIDP and OSS are valid and reliable subjective measures of oral impacts and oral satisfaction, respectively, in an adult Spanish population. Exploring simultaneously these issues may provide useful insights into how satisfaction and impact on well-being are constructed.","2008-11-18","2025-05-05 17:02:20","2025-05-05 17:02:20","","NA","","NA","6","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While many open source products and projects do not measure up to the EQS Directory standards, they can still be used in certain situations.","2008-05","2025-05-05 17:02:21","2025-05-05 17:02:21","","17–20","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Infrastructure; Information technology; Business And Economics; Open source; Open-source software; Software packages; Software design; Trends; Software development; Software quality; 5240:Software & systems; Public domain; 9190:United States; Corporation; Customer relationship management; Ratings & rankings; Request for proposal; United States–US","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, when one plans to study the adequacy of open source software (OSS), it is necessary to have a method of qualification and selection adapted to the characteristics of this type of software and to precisely examine the constraints and risks specific to OSS. Since the open source field has a very broad scope, it is also necessary to use a qualification method that differentiates between numerous candidates to meet technical, functional and strategic requirements. The vast amount of available OSS software requires a methodology to allow for the evaluation of potential candidates to meet business requirements. The QSOS methodology allows for an iterative needs analysis for gauging the technical, functional, and strategic capabilities of OSS products.","2008-05","2025-05-05 17:02:21","2025-05-05 17:02:21","","10–16","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Information systems; Business And Economics; Open-source software; Licenses; Risk; Strategy; Qualifications; ISO standards; 5240:Software & systems; 9190:United States; Component-based software engineering; Need; Qualification; Selection; United States–US","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The approach itself, however, has never been studied. In this paper we take the first step to formalising the Debased architecture assessment of Java Open Source software. We present two aggregate measures: average normalised distance from the train sequence D, and parameter of the fitted statistical model a. Applying these measures to a carefully selected collection of benchmarks we obtain a set of reference values that can be used to assess quality of a system architecture. Furthermore, we show that applying the same measures to different versions of the same system provides valuable insights in system architecture evolution.","2009","2025-05-05 17:02:21","2025-05-05 17:02:21","","198-207","","NA","NA","","","","International Conference on Program Comprehension","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 978-1-4244-3998-0 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The first concerns how the courtship plot of the nineteenth-century novel responded to, and helped to shape, scientific ideas of sexual competition and selection. In The Mill on the Floss (1860), George Eliot strikingly prefigures Darwin's later work on sexual selection, drawing from her own extensive knowledge of the wider debates within which evolutionary theory developed. Maggie Tulliver's characterisation allows Eliot to explore the ethical complexities raised by an increasingly powerful scientific naturalism, where biology is seen to be embedded within morality in newly specific ways. The second strand of the paper examines the extension of scientific method to human mind and motivation which constituted the new psychology. It argues that there are crucial continuities of long-established ethical and religious ideas within this increasingly naturalistic view of human mind and motivation. The contention that such ideas persist and are transformed, rather than simply jettisoned, is illustrated through the example of Thomas Henry Huxley's 1874 essay on automata. Turning finally to focus on Olive Schreiner's Undine (1929) and From Man to Man (1926), the paper explores the importance of these persistent ethical and religious ideas in two novels which remained unpublished during her lifetime. It argues that they produce both difficulty and opportunity for imagining love plots within the context of increasingly assertive biological and naturalistic accounts of human beings.","2009","2025-05-05 17:02:21","2025-05-05 17:02:21","","26-52","","1","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.","2009-07-17","2025-05-05 17:02:23","2025-05-05 17:02:23","","NA","","NA","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is especially true for open source software systems (OSSS), when many developers from different backgrounds interact, share their ideas and contribute towards the development and improvement of a software product. The evolution of all OSSS is a continuous process of source code development, adaptation, improvement and maintenance. Studying changes to the various characteristics of source code can help us understand the evolution of a software system. In this paper, the software evolution process is analyzed using a proposed Evolution curve (E-curve) method, which is based on information theoretic metrics of source code. The method allows identifying major evolution stages and transition points of an analyzed software system. The application of the E-curves is demonstrated for the eMule system.","2009","2025-05-05 17:02:23","2025-05-05 17:02:23","","205-216","","NA","187","","","","Frontiers in Artificial Intelligence and Applications","","","","","","NA","","","","","","","Backup Publisher: Tallinn Univ, Inst Cybernet ISBN: 978-1-58603-939-4 Place: NA Publisher: NA","","","","NA","","Haav, H.

The public archives of OSS projects are used to access historical data on over 5,000 active and mature OSS projects. Using domain knowledge and exploratory analysis, a wide range of variables is identified from the process, product, resource, and end-user characteristics of a project to ensure that the model is robust and considers all aspects of the system. Multiple Data Mining techniques are used to refine the model and data is enriched by the use of Text Mining for knowledge discovery from qualitative information. The study demonstrates the suitability of Data Mining and Text Mining for model building. Results indicate that project type, end-user activity, process quality, team size and project popularity have a significant impact on the defect density of operational OSS projects. Since many organizations, both for profit and not for profit, are beginning to use Open Source Software as an economic alternative to commercial software, these results can be used in the process of deciding what software can be reasonably maintained by an organization.","2009-12","2025-05-05 17:02:23","2025-05-05 17:02:23","","235-251","","4, SI","10","","","","NA","","","","","","English","","","","","","","Backup Publisher: INFORMS ISBN: NA Place: NA Publisher: NA","","","","Open source software; Data mining; Studies; Open source; Software; Open-source software; Software reliability; Research; Time series; Evolution; Operations management; Validation; Teams; Testing; Software quality; Model; 5240:Software & systems; Public domain; Mathematical models; 9130:Experimental/theoretical; 2600:Management science/operations research; Archives & records; 5320:Quality control; Defect; Defects; Maintenance costs; 51921:Libraries; Archives; Business And Economics–Office Equipment And Services","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article deals with the reuse of ADempiere within the framework of the implementation of a service oriented ERP. To operate the migration of the existing code, firstly we reconstituted the architecture of this ERP. This operation made it possible to acquire the technical knowledge necessary to develop services by injection of dependence. The new software resulting from this operation distinctly separates the presentation tier from the back-end. The back-end tier exposes a set of Web services which encapsulates the code of ADempiere.

The principle is separated out into its two primary premises: the first is based on a developer's ability to become productive when joining a new team; the second premise relates to the quality of coordination as the team grows. Three large projects are studied for this purpose: KDE, Plone and Evince. Based on empirical evidence, the paper provides two main contributions: based on the first premise of Brooks' Law, it claims that coordination costs increase only in a very specific phase for Free Software projects. After that, these costs become quasi-constant. Secondly, it shows that a ramp up period exists in Free Software projects, and this period marks the divide between projects that are successful at engaging new contributors from others that only benefit from occasional new contributors.","2009","2025-05-05 17:02:24","2025-05-05 17:02:24","","319-328","","NA","NA","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","","","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn ISBN: 978-1-4244-4897-5 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Research in the area of customization of OSS is rare, however. The process after the deployment of an OSS within a company remains unknown. There is a danger that it is often unstructured and error-prone since OSS develops in a more complex way than proprietary software. Based on our literature study, modifications of open source code do occur also in organizations outside of the software industry. Customization of applications is more common than customization of infrastructure software in these organizations. Therefore, we examine the process of deployment and adaptation of an OSS application software over several update iterations in great detail. This examination shows that this process has similarities with the process of deployment of proprietary software but it also exhibits important differences. Based on this case study, we also suggest a process model for customization of OSS applications in user organizations.","2009","2025-05-05 17:02:24","2025-05-05 17:02:24","","129-142","","NA","299","","","","International Federation for Information Processing","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13 ISBN: 978-3-642-02031-5 Place: NA Publisher: NA","","","","NA","","Boldyreff, C.; Crowston, K.; Lundell, B.; Wasserman, A.

The Digital Video Broadcast Return Channel Satellite (DVB-RCS) NetOps vision for remote management and monitoring aims to provide visibility and Situational Awareness to required communities of interest as well as the ability to view and configure all the operational layers DVB-RCS, including the devices and technology, operations and management, and missions and objectives. An effective management and monitoring solution for DVB-RCS must provide the capability to centrally manage and monitor the system, interoperate between SATCOM and terrestrial networks, consolidate technology, standardize processes, and be proactive rather than reactive. The DISN OSS is DISA's enterprise-wide Service Oriented Architecture for information sharing, management, and monitoring capabilities, based on the Telecommunications Management Network industry standards. The DISN OSS puts the information into the hands of the operators and system managers while making the processes, tools, and technology transparent to the consumer. This paper examines how DVB-RCS implemented the NetOps Portal as an immediate and interim solution to provide Situational Awareness to CENTCOM, as well as how leveraging the DISN OSS can help DVB-RCS achieve assured system and network availability, assured information protection, and assured information delivery in support of high-bandwidth, two-way services for the tactical Warfighter.","2009","2025-05-05 17:02:24","2025-05-05 17:02:24","","2378+","","NA","NA","","","","IEEE Military Communications Conference","","","","","","English","","","","","","","Backup Publisher: IEEE ISBN: 978-1-4244-5238-5 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Interpreting this data involves inferring the masses and abundances of biomolecules injected into the instrument. Because of the inherent complexity of mass spectral patterns produced by these biomolecules, the analysis is significantly enhanced by using visualization capabilities to inspect and confirm results. In this paper we describe Decon2LS, an open-source software package for automated processing and visualization of high-resolution MS data. Drawing extensively on algorithms developed over the last ten years for ICR2LS, Decon2LS packages the algorithms as a rich set of modular, reusable processing classes for performing diverse functions such as reading raw data, routine peak finding, theoretical isotope distribution modelling, and deisotoping. Because the source code is openly available, these functionalities can now be used to build derivative applications in relatively fast manner. In addition, Decon2LS provides an extensive set of visualization tools, such as high performance chart controls. Results: With a variety of options that include peak processing, deisotoping, isotope composition, etc, Decon2LS supports processing of multiple raw data formats. Deisotoping can be performed on an individual scan, an individual dataset, or on multiple datasets using batch processing. Other processing options include creating a two dimensional view of mass and liquid chromatography (LC) elution time features, generating spectrum files for tandem MS data, creating total intensity chromatograms, and visualizing theoretical peptide profiles. Application of Decon2LS to deisotope different datasets obtained across different instruments yielded a high number of features that can be used to identify and quantify peptides in the biological sample. Conclusion: Decon2LS is an efficient software package for discovering and visualizing features in proteomics studies that require automated interpretation of mass spectra. Besides being easy to use, fast, and reliable, Decon2LS is also open-source, which allows developers in the proteomics and bioinformatics communities to reuse and refine the algorithms to meet individual needs.

They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.","2009","2025-05-05 17:02:25","2025-05-05 17:02:25","","532-549","","3-4","109","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD","","","","Internet; Social networks; Open systems; User studies; Consumer\n behaviour","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to consistently manage and access various types of product-related history information throughout the supply chain, it is necessary to develop information networks and databases for sharing that information between firms, and EDI systems play a central role in that context. This paper proposes a distributed traceability system based on open source software which is particularly suitable for small and medium enterprises. To do this, the paper first conducts an exploratory analysis of factors involved in the adoption of traceability systems by small and medium enterprises, based on a review of previous research on traceability and questionnaire survey data. Next, it examines the current situation and problems of RF tags, 2D barcodes and EDI systems, and their linkage with in-house backend systems. Based on the above analysis, the paper proposes a model of a traceability system using open source software which is suitable for small and medium enterprises, and discusses the model's practical implications.","2009","2025-05-05 17:02:25","2025-05-05 17:02:25","","35+","","NA","NA","","","","Electrical and Computer Engineering Series","","","","","","NA","","","","","","","Backup Publisher: WSEAS ISBN: 978-960-474-041-3 Place: Stevens Point, Wisconsin, USA Publisher: World Scientific and Engineering Academy and Society (WSEAS)","","","","open source software; 2D barcodes; EDI; supply chain; traceability systems; medium enterprises; small","","Xi, L.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to detect types, and establish similarities, among Free/Libre/Open Source Software (FLOSS) systems, this paper considers three modular characteristics (functions, files and folders) and their evolution: how they are evolving with size, if they are constant across systems, and whether recurring evolutionary patterns are observed. Using these various-grained characteristics, a set of models for the evolution of modularization are extracted from evolving systems, and then used to extract similarities and types from a wide sample of FLOSS projects. This paper provides three contributions: first, it shows that several models are needed to encompass the variety of modularization patterns; second, it provides three types of models (uni-variate, bi-variate and tri-variate) for the evolution of modularization, with significant goodness-of-fit's. Finally, it shows that two of these patterns alone can interpolate the modular characteristics of the vast majority of a random choice of FLOSS projects.","2009","2025-05-05 17:02:25","2025-05-05 17:02:25","","3-19","","NA","299","","","","International Federation for Information Processing","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13 ISBN: 978-3-642-02031-5 Place: NA Publisher: NA","","","","NA","","Boldyreff, C.; Crowston, K.; Lundell, B.; Wasserman, A.

This phenomenon thus begs the important question of what are the influential factors that affect the success of open source projects. In a quest to deepen our understanding of the evolution of open source projects, this research aims to analyze the success of open source projects by using the theoretical lens of social network analysis. Based on extensive analyses of data collected from online repositories, we study the impact of the communication patterns of software development teams on the demand and supply outcomes of these projects, while accounting for project-specific characteristics.

We cast the subspace segmentation problem as that of choosing the best subset of linear subspaces from a set of candidate subspaces constructed from the data. Under this formulation, subspace segmentation corresponds to facility location, a well studied operational research problem. Approximate solutions to this NP-hard optimization problem can be found by performing maximum-a-posteriori (MAP) inference in a probabilistic graphical model.

A recent literature has focused on the question of the business models explaining how and why firms may draw benefits from such involvement and their connected activities. They can be considered as the building blocks of a new modus operandi of an industry, built on an alternative approach to intellectual property management. Its prospects will depend on both the firms' willingness to rally and its ability to compete with the traditional `proprietary' approach. As a matter of fact, firms' involvement in FLOSS, while growing, remains very contrasted, depending on the nature of the products and the characteristics of the markets. This paper asks why for-profit firms contribute to FLOSS development and why some firms contribute more than others. The common explanation is that FLOSS is often a complement to proprietary software (or hardware or services) that the for-profit firm sells at a positive price. We present an alternative explanation based on the users' skill level. When users are skilled, opening the software is likely to result in a better product because the user base will contribute improvements (find bugs, write fixes and produce new features). We introduce the concept of the dominant user's skill and set up a theoretical model to better understand how it may condition the nature and outcome of the competition between a FLOSS firm and a proprietary firm. We discuss these results in the light of stylized facts drawn from recent trends in the software industry.

I argue that the moral imagination observable in this phenomenon can be understood with reference to its emergence around specific methods of technical production. Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making `good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.","2009-03","2025-05-05 17:02:27","2025-05-05 17:02:27","","51-71","","1","74","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD","","","","ethics; Software; freedom; progress; social form","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key paradox of the global Internet is that it allows individual and collective decision making to co-exist with each other. Open source software (OSS) communities are a globally accelerating phenomenon. OSS refers to groups of programs that allow the free use of the software and further the code sharing to the general and corporate users of the software. The combination of private provision and public knowledge and software, and the seeming paradox of economic versus social motivations have stimulated a wide debate between researchers and policymakers. In this article, we analyze OSS communities from the viewpoint of “intrinsic motivation,” knowledge creation, and collective Internet governance. We believe that the growth of global OSS has fundamental implications for business ethics and the governance of the global Internet in the twenty-first century.","2009-12","2025-05-05 17:02:27","2025-05-05 17:02:27","","523-531","","4","90","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Law; Motivation; Decision making; Social interaction; Studies; Open-source software; Anthropology; Knowledge; Social sciences; Research; Society; Psychological aspects; Internet governance; Knowledge economy; Internet; Corporate governance; 5240:Software & systems; Public domain; 9130:Experimental/theoretical; 1220:Social trends & culture; 2410:Social responsibility; 62133:Offices of Mental Health Practitioners (except Physicians); 9180:International; Business ethics; Global justice; International; Psychologists","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We compare group maintenance behaviors between both core and peripheral members of these groups, as well as behaviors between a group that remains producing software today and one which has since dissolved.

Most studies, based on a popular FLOSS repository (SourceForge). have concluded that the vast majority of projects are failures. This Study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities ire formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success. (C) 2008 Elsevier Inc.

This paper reviews relevant literature related to international operations of knowledge-intensive firms, especially in the software industry. Theoretical development is based here on a combination of the network approach, international new venture theory and inward-outward internationalization. The findings in this study suggest that the international activities of OSS firms can be divided into project activities and business activities. Project activities include inward and outward linkages, and partner identification. Business activities include domestic and partner network activities that can lead to international business as well. For scholars, the framework provides a new approach to explain many international activities of OSS firms by integrating three international business theories. In addition, it provides good starting point for further empirical examination. The framework helps managers gain a better understanding of complex circumstances embedded into the international activities of OSS firms. With that better understanding, the managers can focus their activities, which helps further to improve their firms' competitiveness engendered by the international activities in the OSS development. The framework developed in this study is believed to be the first serious attempt to provide a deeper theoretical understanding of international activities of OSS firms.

Another approach to increase productivity and experience significant cost savings is to utilize Open Source (OS) components in software development. This paper presents the state of the art of how to combine MDD methods with OS software development. The approach is called Open Models software development which is expected to combine the benefits of both worlds. The fundamental idea of Open Models development is to apply community-driven collaborative MDD. In this paper, Open Models development is exemplified by constructing Resource Availability Service (RAS).

The primary difficulty is that software development efforts are complex in terms of both the technical and social aspects of the engineering environment. This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data. For four of the five project success measures, the results indicate that the developed model represents the underlying data well and provides accurate predictions of open source project success indicators.","2009","2025-05-05 17:02:29","2025-05-05 17:02:29","","NA","","NA","NA","","","","PROMISE '09","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781605586342 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","software engineering; FLOSS; agent-based simulation; Bayesian belief networks; data-based models","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This focus on growth generated by the community is referred to as “single factor” growth and is an assumption shared by literature on the diffusion of innovation. The purpose of this research is to attempt to fit a logistic model to a well-known OSS project as a confirmatory exercise supporting the use of a single factor growth model as suggested by the literature. The results show that a logistic model, or any kind of single factor model, is inadequate to describe the diffusion of the OSS project. The paper then explains conceptually and illustrates mathematically why single factor models cannot fully represent the diffusion of any OSS project. A well-known two-factor model drawn from the marketing literature is presented, shown to solve the problem of single factor models, and used to illustrate the importance of marketing in OSS projects. This research suggests that the OSS literature may be overemphasizing the importance of the size of the user and developer community during the initial stages of growth and that during these stages the diffusion of the OSS project is primarily driven by external forces such as advertising or marketing efforts.","2009","2025-05-05 17:02:29","2025-05-05 17:02:29","","91-101","","2","38","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We examine characteristics of municipal government that may influence the adoption of OSS for the delivery of services and to conduct city business. Three characteristics are considered to develop an understanding of city behavior with respect to OSS: capability, discipline, and cultural affinity. Each of these general characteristics contributes to the successful adoption and deployment of OSS by cities. Our goal was to determine the organizational characteristics that promote the adoption of OSS. We conducted a survey to support this study resulting in 3316 responses representing 1286 cities in the Unites States and Canada.

In this research, we characterized effective roles of participants, i.e. participation, on the basis of activities analysis in three online interaction spaces (discussion, documentation and implementation) during a continuous “pushed-by-users” design process of the Python project. Participation is targeted through a methodology articulating: (1) structural analyses (organization of the discussions, regularity and involvement of participants, quotes-based social network) in usage-oriented and development-oriented mailing lists of the projects' discussion space; (2) actions to the code and documentation made by participants in the implementation and documentation spaces. Besides the importance of the users' contribution to the process, OSS design is fostered by some key-participants, the cross-participants, who act as boundary spanners between the developers and the users, helping them to go beyond some barriers to participation.

Among these principles, “Brooks' Law” has been questioned in the Free Software context: large teams of developers, contrary to the law, will not need an increasingly growing number of communication channels. As advocates claim, this is due to the internal characteristics of the Free Software process: the high modularity of the code helps developers to work on comparted sections, without the need to coordinate with all other contriutors. This paper examines Brooks' Law in a Free Software context, and it studies the interaction of contributors to a large Free Software project, KDE. The network of interactions is analyzed and a summary term, the “compaction”, is dynamically evaluated to test how the coordination mechanism evolves over time in the project. This paper argues that the claim of advocates holds true, but with limitations: in the KDE project, the few initial developers needed a significant amount of communication. The growth of KDE brought the need to break the number of overall communication channels to a significant extent. Finally, an established amount of 300 developers currently needs the same amount of communication as when the developers were only 10. We interpret this result by arguing that Brooks' Law holds true among the core developers of any large Free Software project.","2009","2025-05-05 17:02:30","2025-05-05 17:02:30","","274-283","","NA","299","","","","International Federation for Information Processing","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13 ISBN: 978-3-642-02031-5 Place: NA Publisher: NA","","","","NA","","Boldyreff, C.; Crowston, K.; Lundell, B.; Wasserman, A.

It is important to understand, how to report empirical studies of OSS in order to make them useful for practitioners and researchers. Research aim: The aim of our research is to gain insights in the state of the practice of reporting empirical studies of OSS in order to identify the gaps to be filled for improving the quality of evidence being provided for OSS. Method: To that end, we decided to systematically review the empirical studies of OSS. A total of 63 papers reporting empirical studies were selected from the four editions of the Proceedings of the International Conference on Open Source Systems. The data were extracted and synthesised from the selected papers for analysis. Results and conclusions: We have found that the quality of the reported OSS-related empirical studies needs to be significantly improved. Based on the results of our systematic review and general principles of reporting good empirical research, we present a set of guidelines for reporting OSS-related empirical studies. The suggested guidelines are expected to help the research community to improve the quality of reported studies.","2009","2025-05-05 17:02:30","2025-05-05 17:02:30","","156-169","","NA","299","","","","International Federation for Information Processing","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13 ISBN: 978-3-642-02031-5 Place: NA Publisher: NA","","","","NA","","Boldyreff, C.; Crowston, K.; Lundell, B.; Wasserman, A.

We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.","2009-04","2025-05-05 17:02:30","2025-05-05 17:02:30","","277-295","","2","19","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER","","","","Social capital; Knowledge; Networks; Software industry","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The framework uses `agents' to represent developers and models the costs associated with first comprehending and then applying necessary changes to a fictitious code base. It also considers agent `memory recall' of their own code as a fundamental part of the framework and the fact that, with higher numbers of developers, maintenance of a higher proportion of other developers' code (rather than their own) is an inevitable, yet realistic aspect. Through exploration of the results and data produced by the simulation. We are able to explore `desirable' features that are part of simulating software evolution; as a discussion of the issues raised by the framework, we provide a set of class data from four open-source systems by way of comparison and show that trends in those systems are comparable with results generated by the simulation.

A number of highly influential papers have argued that the self-fulfilling nature of (even false) theories provides the underlying mechanism through which economics has adversely shaped not just social science but also management practice and individual behavior. We question these arguments and argue that there are important boundary conditions to theories falsely fulfilling themselves, boundary conditions that have hitherto been unexplored in organizational research, and boundary conditions that question the underlying premises used by organizational scholars and social scientists to attack economics. We specifically build on highly relevant findings from social psychology, philosophy, and organizational economics to show how (1) objective reality and (2) human nature provide two important boundary conditions for theories (falsely or otherwise) fulfilling themselves.

Design and requirements are kept more as informal knowledge, rather than formally described and assessed. This paper attempts to recover the SE concepts of software design and architectures from three FLOSS case studies, sharing the same application domain (i.e., Instant Messaging). Its first objective is to determine whether a common architecture emerges from the three systems, which can be used as shared knowledge for future applications. The second objective is to determine whether these architectures evolve or decay during the evolution of these systems. The results of this study are encouraging: albeit no explicit effort was done by FLOSS developers to define a high-level view of the architecture, a common shared architecture could be distilled for the Instant Messaging application domain. It was also found that, for two of the three systems, the architecture becomes better organised, and the components better specified, as long as the system evolves in time.","2009","2025-05-05 17:02:31","2025-05-05 17:02:31","","34-46","","NA","299","","","","International Federation for Information Processing","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13 ISBN: 978-3-642-02031-5 Place: NA Publisher: NA","","","","NA","","Boldyreff, C.; Crowston, K.; Lundell, B.; Wasserman, A.

We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters.

Architectural decay is, potentially, a major issue in Free/Libre/Open Source Software (FLOSS) projects, since developers sporadically joining FLOSS projects do not always have a clear understanding of the underlying architecture, and may break the overall conceptual structure by several small changes to the code base. This paper investigates whether the structure of a FLOSS system and its decay can also be influenced by the repository in which it is retained: specifically, two FLOSS repositories are studied to understand whether the complexity of the software structure in the sampled projects is comparable, or one repository hosts more complex systems than the other It is also studied whether the effort to counteract this complexity is dependent on the repository, and the governance it gives to the hosted projects. The results of the paper are two-fold: on one side, it is shown that the repository hosting larger and more active projects presents more complex structures. On the other side, these larger and more complex systems benefit from more anti-regressive work to reduce this complexity.","2009","2025-05-05 17:02:31","2025-05-05 17:02:31","","169-178","","NA","NA","","","","European Conference on Software Maintenance and Reengineering","","","","","","NA","","","","","","","Backup Publisher: IEEE Comp Soc ISBN: 978-0-7695-3589-0 Place: USA Publisher: IEEE Computer Society","","","","NA","","Winter, A.; Knodel, J.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In future work, we intend to correlate comment density with project success or failure.","2009","2025-05-05 17:02:32","2025-05-05 17:02:32","","195+","","NA","NA","","","","International Conference on Software Engineering","","","","","","English","","","","","","","Backup Publisher: ACM; IEEE; IEEE Comp Soc; SIGSOFT ISBN: NA Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open Source Software (OSS) has becoming widely adopted by commercial, public and academic organisations. Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world. OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization’s success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems. The main aim of this paper is to measure the evolution of OSS using, Eclipse Metrics (EM), with Guice software (GS) as a case study. In addition, this paper gives a brief literature review on OSS and how it has evolved.","2009","2025-05-05 17:02:32","2025-05-05 17:02:32","","211–218","","NA","NA","","","","NISS '09","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 9780769536873 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. Conclusion: We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care. (C) 2009 Elsevier Ireland Ltd.

We use time series analysis techniques to study the time dependence of open-source software activities. The activities of open-source Software projects are extracted from mailing lists, bug reports, and revision history. Three mailing list (Linux, FreeBSD, and Apache HTTP), two bug archives (Eclipse and Apache Software Foundation), and one revision history (Apache Software Foundation) are mined.

Subsequently, understanding the roles these software informalisms take in a new formulation of the requirements development process for OSS is the focus of this study. This focus enables considering a reformulation of the requirements engineering process and its associated artifacts or (in)formalisms to better account for the requirements when developing OSS systems.

Building upon Lave and Wenger's theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: “situated learning” (the process of acting knowledgeably and purposefully in the world) and “identity construction” (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code).

Our results provided evidence of virtual organizational learning in OSS development projects and support for several factors as determinants of performance. Team size was a significant predictor, with mid-sized project teams functioning best. Teams of three to seven developers exhibited the highest efficiency over time and teams of eight to 15 produced the lowest mean time for bug resolution.

Nearly all open source software is free software; the two terms describe almost the same category of software. But they stand for views based on fundamentally different values. Open source is a development methodology; free software is a social movement. As the advocates of open source draw new users into the community, free software activists must work even more to bring the issue of freedom to those new users attention.","2009-06","2025-05-05 17:02:34","2025-05-05 17:02:34","","31","","6","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Community; Open source; Software; Free software; Freedom; 5240:Software & systems; Freeware; 9190:United States; Open; Definitions; Differences; United States–US; Computers–Data Communications And Data Transmission Systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS/FS alternatives complicate an already complex information goods market plagued by piracy concerns. Although producer perspectives on software pricing and piracy controls have been addressed extensively, consumers' perspective and willingness to pay for commercial software is not very well understood. This paper empirically determines willingness to pay for a leading commercial software application (Microsoft Office) in the presence of an OSS/FS alternative. A contingent valuation approach is used to elicit willingness to pay for the application. The research design employs a 2 x 2 x 2 experiment to investigate the impact of preventive control, deterrence control, and OSS/FS alternative. The results indicate that the availability of an OSS/FS alternative has little impact on willingness to pay for Microsoft Office. However, piracy controls significantly increase willingness to pay for Microsoft Office, even in the presence of OSS/FS alternatives.","2009-06","2025-05-05 17:02:34","2025-05-05 17:02:34","","218-236","","2","20","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Open source; Software; Open-source software; Consumers; Intellectual property; Software development; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 51321:Software Publishers; Software industry; Freeware; 9190:United States; 1130:Economic theory; Contingent valuation; Copyright infringement; Correlation analysis; Cost control; Deterrence; Information industry; Piracy; Prevention; Profitability; Profits; Valuation; Willingness to pay; Computers–Information Science And Information Theory; United States–US; 51929:Web Search Portals; All Other Information Services","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this paper is to describe the software architecture. Design/methodology/approach - The DEM chosen uses position, orientation, velocity and angular velocity as independent variables of simulated particles which are subject to explicit leapfrog time-integration scheme (Lagrangian method). The three-dimensional dynamics equations based on the classical Newtonian approach for the second law of motion are used. The track of forces and moments acting on each particle is kept at every time step. Contact forces depend on the particle geometry overlap and material properties. The normal, tangential and moment components of interaction force are included. Findings - An effort is undertaken to extract the underlying object oriented abstractions in the DEM. These abstractions are implemented in C++, conform to object oriented design principles and use design patterns. Based on that, a software framework is developed in which the abstractions provide the interface where the modelling methods can be plugged-in. Originality/value - The resulting YADE-OPEN DEM framework is designed in a generic way which provides great flexibility when adding new scientific simulation code. Some of the advantages are that numerous simulation methods can be coupled within the same framework while plug-ins can import data from other software. In addition, this promotes code improvement through open-source development and allows feedback from the community. However implementing such models requires that one adheres to the framework design and the YADE framework is a new emerging software.

We introduce here a new open source software tool, rNMR, which provides a simple graphics-based method for visualizing, identifying, and quantifying metabolites across multiple one- or two-dimensional NMR spectra. rNMR differs from existing software tools for NMR spectroscopy in that analyses are based on regions of interest (ROIs) rather than peak lists. ROIs contain all of the underlying NMR data within user-defined chemical shift ranges. ROIs can be inspected visually, and they support robust quantification of NMR signals. ROI-based analyses support simultaneous views of metabolite signals from up to hundreds of spectra, and ROI boundaries can be adjusted dynamically to ensure that signals corresponding to assigned atoms are analyzed consistently throughout the dataset. We describe how rNMR greatly reduces the time required for robust bioanalytical analysis of complex NMR data. An rNMR analysis yields a compact and transparent way of archiving the results from a metabolomics study so that it can be examined and evaluated by others. The rNMR website at http://rnmr.nmrfam.wisc.edu offers downloadable versions of rNMR for Windows, Macintosh, and Linux platforms along with extensive help documentation, instructional videos, and sample data.

I demonstrate how F/OSS developers contest and specify the meaning of liberal freedom – especially free speech – through the development of legal tools and discourses within the context of the F/OSS project. I highlight how developers concurrently tinker with technology and the law using similar skills, which transform and consolidate ethical precepts among developers. I contrast this legal pedagogy with more extraordinary legal battles over intellectual property, speech, and software. I concentrate on the arrests of two programmers, Jon Johansen and Dmitry Sklyarov, and on the protests they provoked, which unfolded between 1999 and 2003. These events are analytically significant because they dramatized and thus made visible tacit social processes. They publicized the challenge that F/OSS represents to the dominant regime of intellectual property (and clarified the democratic stakes involved) and also stabilized a rival liberal legal regime intimately connecting source code to speech.

Particularly free and open source software, used for the experimentation here shown, are Blender and PostGIS; the first one has been used to build and structure three-dimensional data, the second one for data allocation. These software interact using scripts, written in Python language. Buildings have been modeled upon the GIANT3D model (Geographical Interoperable Advanced Numerical Topological 3-Dimensional Model) developed in the research “PRIN 2004”, regarding “Evolved structure of numerical cartography for Gis and Web-GIS”. Python scripts, activated by Blender, allow to allocate data into a spatial database implemented through PostgreSQL and PostGis, that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, are so transferred in PostGIS. These information can be retrieved by Blender using other Python scripts, so Blender fully interacts with 3D data allocated in PostGIS. These data can be also accessed by many other clients, both directly using a database client, as using other protocols (like HTTP on the internet). Next step is to build an open source viewer, or a plugin for internet browsers, that allows client to visualize, explore and inquiry 3D model, retrieving data from database.","2010","2025-05-05 17:02:35","2025-05-05 17:02:35","","120-125","","2W","38-4-8","","","","International Archives of the Photogrammetry Remote Sensing and Spatial\n Information Sciences","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","Peled, A.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although industrial applications traditionally rely on PLC-based hardware and, in any case, proprietary software, i.e. operating systems and development tools, in recent years dramatic improvements in hardware computer power and free software quality made realistic the employment of architectures based on PC-compatible hardware and GNU/Linux software, more common in the research community. The advantages of a free infrastructure, that can become the terrain of fruitful cooperation between research institutions and companies, can be exploited mainly in fields, in which the added value is in the application, i.e. in mechanical and algorithmic solutions, and where the point of view is that of aware users of an infrastructure, rather than of R&D competitors. This is the case of the project presented in the following, representing a success story in which the discussion between a research group and a small enterprise led to the identification of the requirements and the joined development of a common software infrastructure. When the project started in 2004, both partners, i.e. the Autonomous robotic systems and control group of CNR-ISSIA and Green Project Srl, had to substitute the obsolete platforms of their marine robots and marking machines for casting products in steelworks with a stable software and hardware infrastructure able of transparently integrating technological improvements while remaining compatible with the past (backward compatibility). On the basis of considerations, discussed below, about system reliability, development and maintenance costs (including human resources), foreseen compatibility and general technical soundness, the choice was to verify the possibility of using standard GNU/Linux for embedded real-time applications. The result is the main technical contribution of this chapter, i.e. the practical demonstration of the possibility of using standard GNU/Linux for implementing embedded real-time control systems working up to a sampling frequency of at most 2 Khz. Furthermore, four years later, the developed system is still demonstrating its capabilities transparently integrating technological improvements and increasing more and more its performance thanks to the new real-time properties of the Linux kernel. A first operative release of the platform was completed in 2005 and integrated with the CNR-ISSIA Charlie unmanned surface vehicle (USV) for robotics research. A second application was the porting to the platform of the software of the control system of Hammer, a steelwork industrial machine used for marking continuous casting products, developed by Greenproject s.r.l. At the moment, the platform is supporting the development of the ALANIS (Aluminium Autonomous Navigator for Intelligent Sampling) USV1 for surface and underwater coastal monitoring. Moreover, the integration with generic field buses and image acquisition systems is being carried out. After an introduction reporting a summary of related research in the field and a discussion of the platform requirements, the key points of the followed methodology for making GNU/Linux real-time will be presented. Finally, two applications, a research one and an industrial one, pointing out the basic real-time structures that the platform is required to implement, will be described.","2010","2025-05-05 17:02:35","2025-05-05 17:02:35","","211-225","","NA","NA","","","","Computer Science Technology and Applications","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-60741-661-6 Place: 400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA Publisher: NOVA SCIENCE PUBLISHERS, INC","","","","NA","","Hayes, M.; Johansen, I.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.","2010","2025-05-05 17:02:35","2025-05-05 17:02:35","","NA","","NA","NA","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-4244-8629-8 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","software metrics; software quality; Software maintenance; open-source\n software","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper explains the architecture of the resulting platform. With a minimum of custom code, we have created a powerful platform that meets our requirements. This integration, described in the paper, is of use to organizations wishing to build their own media platform using open source components.","2010","2025-05-05 17:02:36","2025-05-05 17:02:36","","98-103","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Knowledge Syst Inst Grad Sch ISBN: 978-1-891706-28-8 Place: NA Publisher: NA","","","","NA","","Nesi, P.; Ng, K.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on the experience of QualiPSo Competence Centres, we observe how such a Network is working as a mechanism for sharing success stories, failures, questions, recommendations, best practices, and any kind of information that could help the establishment of a solid international collaborative environment for supporting quality in FLOSS. New Competence Centres are invited to the QualiPSo Network after their proposals are evaluated by the QualiPSo Competence Centres Board to ensure that the prospective Competence Centre is compliant with the QualiPSo Network Agreement, sharing a common vision and ethics. Each Competence Centre acts in its geographical region to increase the awareness of FLOSS and to better prepare the IT workforce for developing and using FLOSS based solutions. As of 2009, the process for Competence Centre creation is sustainable and reusable; guidelines for establishing proposals and opening new Competence Centres have been created, and promotion of Qualipso Competence Centres is done world wide from India to USA thanks to key initiatives such as the Open World Forum and the FLOSS Competence Centre Summit. This lecture will expose how these Competence Centres relate to each other, which governance model is used and, based on existing experiences, will describe how they currently operate in Europe and Brazil and what is planned in Italy, Belgium, Japan, and China for 2010.","2010","2025-05-05 17:02:36","2025-05-05 17:02:36","","348-353","","NA","319","","","","IFIP Advances in Information and Communication Technology","","","","","","English","","","","","","","Backup Publisher: Int Federat Informat Proc Work Grp 2 13 ISBN: 978-3-642-13243-8 Place: HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY Publisher: SPRINGER-VERLAG BERLIN","","","","NA","","Agerfalk, P.; Boldyreff, C.; GonzalezBarahona, J.

Unfortunately, manual analysis is costly, error-prone, and often yields results late for decision making. In this paper we propose linking OSS data sources using semantic web technologies as foundation for providing integrated indicators project status analysis. We introduce the design concept of a project monitoring cockpit, Pro-MonCo, and evaluate the feasibility and effectiveness with a pro-totype for calculating communication metrics in a real-world context, the Apache Tomcat project.

To verify these relationships, we analyzed 6,773 Free Software projects from the SourceForge.net repository. The results indicated that attractiveness is indeed correlated to some source code metrics. This suggests that measurable attributes of the project source code somehow affect the decision to contribute and adopt a Free Software project.

This paper aims to illustrate that if Free and/or Open Source Software is to be used as a building block to bridge the ""digital divide"" a more social and environmental perspective, which embraces the philosophy behind the software, needs to complement the technical perspective. The human environmental model is presented as a useful alternative which, if embraced, can inform more holistic information and communication technology (ICT) policies. Design/methodology/approach - Through a review of diffusion of innovations models an alternative diffusion framework is described and applied to an interpretive open source case study in South Africa. Findings - Contemporary diffusion and innovation models are narrowly focused on IT as a purely technological linear phenomenon. This perspective also underlies many ICT policies. A more socio-technical adoption model can assist in providing a more holistic approach to ICT policy development. Originality/value - The application of a new innovation model, the human environmental model, to ICT policy provides a holistic framework in which the complexity of the innovation process can be reflected in policy. Such an approach to ICT policy formulation will assist with broadening the perspective of policy makers from IT as a technical solution to IT as part of a socio-technical solution and recognise the duality of the innovation process.","2010","2025-05-05 17:02:36","2025-05-05 17:02:36","","108–123","","1","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Philosophy; Information technology; Studies; Open-source software; Diffusion; Organizational change; Economic; Technological change; Innovations; Perceptions; Business process reengineering; Communication channels; Departments; Diffusion of innovations; Environmental modeling; Environmentalists; Developing countries–LDCs","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.","2010","2025-05-05 17:02:37","2025-05-05 17:02:37","","1–5","","NA","NA","","","","ICSM '10","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781424486304 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the geomorphologic survey, different landforms have been identified in the area, including structural, anthropogenic, fluvial, karst, and slope forms. In particular, the majority of the slope forms are complex (from topple to rotational slides and falls), but there are also minor forms like debris flows and mudslides. To manage geomorphological data, an Open Source GIS was used, which contained the following components: QuantumGIS, System for Automated Geoscientific Analyses (SAGA), GIS and Geographic Resources Analysis Support System (GRASS), GIS for Digital Elevation Model (DEM) generation. A key aim was to make the project-derived data available over the Web. This was achieved using MapServer which allows for the representation of the derived geospatial data with pMapper providing the graphical Web interface. Our study highlights the process dynamics of run-off erosion in Olvera derived through the use of advanced computer-based mapping tools. The resulting map products and interpretations are available via the Internet.

Therefore, our approach is based on an adaptive heartbeat mechanism, in which the timeout is estimated from past response times.

Based on the systematic literature review method, the authors reviewed publications from 24 journals and seven conference and workshop proceedings, published between 1998 and 2008. From a population of 24,289 papers, the authors identified 112 papers that provide empirical evidence on how organizations actually adopt OSS. The authors show that adopting OSS involves more than simply using OSS products. The authors moreover provide a classification framework consisting of six distinctly different ways in which organizations adopt OSS. The authors find that existing research on OSS adoption does not sufficiently describe the context of the organizations studied, and it fails to benefit fully from related research fields.","2010-11","2025-05-05 17:02:37","2025-05-05 17:02:37","","1133","","11","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Open source; Open-source software; Technology adoption; Software development; Systematic review; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Literature reviews; Computers–Data Base Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Structural complexity, an architectural concern, makes software projects more difficult to understand, and consequently more difficult to maintain and evolve. The contributors in a free software project exhibit different levels of participation in the project, and can be categorized as core and peripheral developers. Research aim: This research aims at characterising the changes made to the source code of 7 web server projects written in C with respect to the amount of structural complexity added or removed and the developer level of participation. Method: We performed a observational study with historical data collected from the version control repositories of those projects, recording structural complexity information for each change as well as identifying each change as performed by a core or a peripheral developer. Results and conclusions: We have found that core developers introduce less structural complexity than peripheral developers in general, and that in the case of complexity-reducing activities, core developers remove more structural complexity than peripheral developers. These results demonstrate the importance of having a stable and healthy core team to the sustainability of free software projects.","2010","2025-05-05 17:02:38","2025-05-05 17:02:38","","21–29","","NA","NA","","","","SBES '10","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9780769542737 Place: USA Publisher: IEEE Computer Society","","","","FLOSS; Free Software; Open Source software; Periphery; Empirical Software Engineering; Structural Complexity; Core","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we here propose an information system that facilitates the use of BIM for geo-analysis purposes. BIM4GeoA is a concept for combining existing open source software and open specification for efficient data management and analysis of Building Information within its boarder context. The core components are the spatial database PostgreSQL/PostGIS, the building information server, the industrial foundation class (IFC), the Google Earth 3D viewer, and the existing 3D OGC standard (KML, CityGML). This paper presents the procedure used to enable the development of this new expert system as applied to the context of 3D Web GIS. A thorough analysis of the strength and weakness of these different components has been undertaken to employ it is strength and override its weakness. The system architecture is operationally used in developing different applications for the management of a university campus; a large potential is provided for operational tasks of facility management department, such as utilities infrastructure, as well as public community (student, staff) like routing application, searching for a person with defined criteria.","2010","2025-05-05 17:02:38","2025-05-05 17:02:38","","45-49","","W15","38-4","","","","International Archives of the Photogrammetry Remote Sensing and Spatial\n Information Sciences","","","","","","English","","","","","","","Backup Publisher: Int Soc Photogrammetry & Remote Sensing ISBN: NA Place: BAHNHOFSALLE 1E, GOTTINGEN, 37081, GERMANY Publisher: COPERNICUS GESELLSCHAFT MBH","","","","Open Source; Information system; 3D GIS; BIM; CAD; Open Specification","","Kolbe, T.

A virtual social network is therefore formed through a mailing list, in which, each subscriber could be a node of the network, and the communications (email messages) could be the links of the network. Due to the virtual property of this network, physical (geographical) distance between network nodes is usually considered irrelevant. Instead, what is more important is the conceptual distance that captures the key properties of this virtual network. This paper studies the open-source software developer network. Two types representation of the conceptual distance, message reply distance and common keyword distance, are defined. Appling these two types of conceptual distances, the mailing list of Linux kernel project is mined and virtual networks are constructed and analyzed. The evolution of Linux Kernel Mailing List social network is studied, where Mantel test is used to study the similarities and correlations between social networks. The study shows that in open-source software projects, (1) conceptual distances could be the key components in constructing the workspace of the developer network, and (2) Mantel test could be a powerful tool in studying the network.","2010","2025-05-05 17:02:39","2025-05-05 17:02:39","","89-104","","NA","NA","","","","Computer Science Technology and Applications","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-61668-436-5 Place: NA Publisher: NA","","","","NA","","Taylor, J.

In contrast, research on the corresponding “receiving” side of the innovation process is scarce. We address this gap, studying how existing OSS code is reused and serves as an input to further OSS development. Our findings are based on a survey with 686 responses from OSS developers. As the most interesting results, our multivariate analyses of developers' code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early-as the “credible promise” in OSS-leads to increased reuse. Finally, we identify developers' interest in tackling difficult technical challenges as detrimental to efficient reuse-based innovation. Beyond OSS, we discuss the relevance of our findings for companies developing software and for the receiving side of open innovation processes, in general.","2010-12","2025-05-05 17:02:39","2025-05-05 17:02:39","","868-901","","12, SI","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Information systems; Studies; Open source; Open-source software; Software development; Software quality; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; Systems development; Literature reviews; Code reuse; Programmers; Multivariate analysis; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines this corporatizing effect by studying the relationship between peer-oriented social structures and goal-oriented technical structures in the Plone community. Social structures are said to exhibit assortative mixing, a like attract like characteristic whereas technical structures exhibits an opposite effect of disassortative mixing. Our first finding suggests that the patterns of collaborative contributions and interdependences among software modules exhibit the characteristic of disassortative mixing. Specifically, Plone developers were more likely to contribute to modules that already have a high concentration of contributions, which in turn lead to an increase in module reuse over time. This finding contributes to the debate of whether social systems are strictly assortative, and technological systems strictly disassortative (Newman, 2002). Our second contribution concerns the impact of corporatizing OSS projects, suggesting that corporatizing OS development had the effect of weakening the social organizing among developers, and shifted the patterns of contributions to adhere with the technical requirements.","2010","2025-05-05 17:02:40","2025-05-05 17:02:40","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: SAP Univ Alliances; IBM ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at Source Forge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects.","2010","2025-05-05 17:02:40","2025-05-05 17:02:40","","179-210","","3","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Project communities and customer pipelines are not the same thing, although some participants belong to both groups. This creates confusion in the business and tension with the community. F/LOSS communities have been on the rise for the past two decades. Companies began to form around F/LOSS projects in the early 1990s, with some creating their own F/LOSS projects and some wrapping themselves around existing projects. This has created tension between company managers who are trying to earn profits from software that is ""available for free,"" and from developers in communities that do not necessarily want to create software for someone else's corporate gain. This happens regardless of whether the company created the F/LOSS-licensed project itself, or participates in external communities around other projects, or both. This article demonstrates that separating the concepts of community and customer, and of project and product, allows a business to manage clearly both challenges of developing an engaged community and maximizing profits.","2010-10","2025-05-05 17:02:40","2025-05-05 17:02:40","","5–13","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Community; Canada; Business And Economics; Collaboration; Marketing; Customers; Business; Internet; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Project; Loss; 9172:Canada; Customer relationship management; 2400:Public relations; Customer; Product; Profit maximization; Research & development–R&D","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, download counts and averages do not convey as much information as the patterns in the original downloads time series. In this research, we propose a method to increase the expressiveness of mere download rates by considering download patterns against software releases. We apply experimentally our method to the most downloaded projects of Source Forge's history crawled through the FLOSSMole repository. Findings show that projects with similar usage can have indeed different levels of sensitivity to releases, revealing different behaviors of users.

Methods Five beagle dogs were used. Four premolars in the mandible (P-3(3), P-4(4)) were hemi-sected, the distal roots were removed and the fresh extraction socket filled with Bio-Oss (R) Collagen. The mucosa was mobilized and the extraction site was closed with interrupted sutures. The tooth extraction and grafting procedures were scheduled in such a way that biopsies representing 1 and 3 days, as well as 1, 2 and 4 weeks of healing could be obtained. The dogs were euthanized and perfused with a fixative. Each experimental site, including the distal socket area, was dissected. The sites were decalcified in EDTA, and serial sections representing the central part of the socket were prepared in the mesio-distal plane and parallel with the long axis of the extraction socket. Sections were stained in hematoxylin and eosin and were used for the overall characteristics of the tissues in the extraction socket. In specimens representing 1, 2 and 4 weeks of healing the various tissue elements were assessed using a morphometric point counting procedure. Tissue elements such as cells, fibers, vessels, leukocytes and mineralized bone were determined. In deparaffinized sections structures and cells positive for tartrate-resistant acid phosphatase activity (TRAP), alkaline phosphatase and osteopontin were identified. Results The biomaterial was first trapped in the fibrin network of the coagulum. Neutrophilic leukocytes [polymorphonuclear (PMN) cells] migrated to the surface of the foreign particles. In a second phase the PMN cells were replaced by multinuclear TRAP-positive cells (osteoclasts). The osteoclasts apparently removed material from the surface of the xenogeneic graft. When after 1-2 weeks the osteoclasts disappeared from the Bio-Oss (R) granules they were followed by osteoblasts that laid down bone mineral in the collagen bundles of the provisional matrix. In this third phase the Bio-Oss (R) particles became osseointegrated. Conclusions It was demonstrated that the incorporation of Bio-Oss (R) in the tissue that formed in an extraction wound involved a series of different processes.

For laboratory lectures, we need a tool that is complete and easy to use. In this work we present a Java library which is oriented to teaching. This means that we have designed and built the library thinking in readability and understanding instead of efficiency. In this paper we present the open source project JavaVis, oriented to Computer Vision teaching. It consists of a framework with several features that make it useful for that purpose. It was designed to be easy to use: the user does not have to deal with internal structures and graphical interface, and adding a new algorithm is a simple task. We have developed three different modules, based on three different needs we have noticed in our subjects. The first one is a basic library for image processing. Besides the previously commented features, it supports geometrical data (edges, segments, points, etc.). The second module is based on the same working schema as the first one, but applied to 3D data. These two modules are enough for testing many well-known algorithms. They also suit the programming needs of students and teachers, as they can easily develop their own algorithms for the JavaVis framework. All JavaVis functions can be launched both from command line, as well as with the JavaVis Graphical User Interface. Finally we have extended JavaVis with a third module consisting of a visual desktop where different Computer Vision functions can be easily placed and connected. Its purpose is to visualize intermediate results in processes involving several functions, helping their better understanding. Once the library is presented, we focus on the experience using this library in several computer science courses. Our main goal using this library is that the students understand what they are doing. We have taken questionnaires during two years in order to know the improvement the students have gotten using the library. Results are shown and conclusions are drawn.","2010","2025-05-05 17:02:41","2025-05-05 17:02:41","","4514-4522","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-84-613-5538-9 Place: NA Publisher: NA","","","","NA","","Chova, L.

To better understand the turnover of members in OSS projects, we base our study on Herzberg's two-factor theory to investigate whether hygiene factors will lead to members' dissatisfaction. At the same time, we draw on Mobley's model of withdrawal decision process to hypothesize the relationship between dissatisfaction and perceived turnover. We develop a research model and present hypotheses that should be tested in the future. To empirically assess this model, we intend to survey OSS project members through the largest development platform Sourceforge.

We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project.

The use of spatially explicit analysis has increased during the last decade, with the consequent expansion of GIS application in ecology. During the last years, geo-information technology has been developed within the Free/Open Source Software (FOSS) community, resulting in new open source formats and several GIS packages. However, proprietary packages seem still to be the first choice for herpetologists, thus involving non negligible costs for GIS technology adoption. Additional costs arise from environmental data, which are usually expensive, worsening in the case of large study areas. An alternative solution is to use freely available data, despite a possible decrease of resolution. In this review, we aim to show the feasibility of spatial analysis within FOSS GIS packages, rank these packages using the number of available tools and list several data sources freely available on the Internet. We listed several websites providing the most important free data for spatial analysis, i.e. altitude and derived data; past, current and future climatic series data; and satellite derived data. We provide also a list of the most commonly used functions in GIS analysis and their availability in the six software compared in this study (ArcGIS; gvSIG; ILWIS; Quantum GIS; GRASS; and DIVA-GIS).

In such perspective, it has become common place to refer to FOSS as a manifestation of collective intelligence where deliverables and artefacts emerge by virtue of mere cooperation, with no need for supervising leadership. We show that this assumption is based on limited understanding of the software development process, and may lead to wrong conclusions as to the potential of peer production. The development of a less than trivial piece of software, irrespective of whether it be FOSS or proprietary, is a complex cooperative effort requiring the participation of many (often thousands of) individuals. A subset of the participants always play the role of leading system and subsystem designers, determining architecture and functionality; the rest of the people work “underneath” them in a logical, functional sense. While new and powerful forces, including FOSS, are clearly at work in the post-industrial, networked economy, the currently ingenuous stage of research in the field of collective intelligence and networked cooperation must give way to a deeper level of consciousness, which requires an understanding of the software development process.","2010","2025-05-05 17:02:43","2025-05-05 17:02:43","","285-292","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-906638-84-9 Place: NA Publisher: NA","","","","NA","","Tsui, E.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In more recent years, FOSS is becoming an increasingly important element in strategies for development and implementation of information and communication technologies also in developing countries. Mainstream research on FOSS has catered to the underlying principles or freedom, open organizational forms, and on its economical aspects. The purpose of this paper is to shed new light on the actual consequences of FOSS, often left in the background. Design/methodology/approach - The paper examines where FOSS principles' assumptions are likely to be more evident: in contexts of developing countries, which are geographically and organizationally far from the original environment of FOSS. A mixed methodology characterizes this work: quantitative and qualitative methods bring readers' attention to unusual empirical settings and downplayed organizational processes of information technology (IT) implementation and adoption. Findings - The consequences of FOSS on IT implementation and actual use are ambivalent. It is argued that FOSS adoption does not happen spontaneously, neither by decree, and that the relevance of open technologies as public goods remains in the different role of local actual technical and organizational capabilities, and environment conditions. Originality/value - Such a focus complements existing studies on the economical relevance of FOSS, which are not the focus of this paper.","2010","2025-05-05 17:02:43","2025-05-05 17:02:43","","42–56","","1","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; India; Politics; Philosophy; Decision making; Information technology; Studies; Open source; Software; Information; Competition; Technology adoption; Influence; Costs; open-source software; South Africa; Public domain; Economic; Technological change; Proprietary; Developing country; Free; Small & medium sized enterprises-SME; Computer literacy; Development strategies; Environmental impact; National security; Skill development; Skills; Developing countries–LDCs; communications technology","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects are typically organized as edge organizations lacking an explicit management regime to control and coordinate decentralized project work. However, a growing number of OSS projects are developing, delivering, and supporting large-scale software systems, displacing proprietary software alternatives. Recent empirical studies of OSS projects reveal that OSS developers often self-organize into organizational forms we characterize as evolving socio-technical interaction networks (STINs). STINs emerge in ways that effectively control semi-autonomous OSS developers and coordinate project activities, producing reliable and adaptive software systems. In this paper, we examine how practices and processes enable and govern OSS projects when coalesced and configured as contingent, socio-technical interaction networks. We draw on data sources and results from two ongoing case studies of governance activities and elements in a large OSS project.","2010","2025-05-05 17:02:43","2025-05-05 17:02:43","","130-142","","NA","319","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: Int Federat Informat Proc Work Grp 2 13 ISBN: 978-3-642-13243-8 Place: NA Publisher: NA","","","","NA","","Agerfalk, P.; Boldyreff, C.; GonzalezBarahona, J.

Openness is often regarded as a dichotomous variable (open-source vs. closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.","2010-09","2025-05-05 17:02:43","2025-05-05 17:02:43","","248-256","","3","19","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","Open source software; Studies; Business And Economics; Open source; Software engineering; Software; Open-source software; Intellectual property; Consumer electronics; 9130:Experimental/theoretical; Value chain; Open; Value capture; Designers; Openness","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This approach is used to examine how F/OSS may contribute to a people-centred and development-oriented information society. Three questions are asked: (1) Is it helpful to view F/OSS as market or non-market production? (2) How is F/OSS distributed and marketed? (3) How does F/OSS rely on gendered labour? By analysing existing writings on F/OSS, it is concluded that market production should not be privileged over other modes of production; state intervention is required to ensure an equitable distribution of F/OSS; and gendered labour needs to be made visible in the F/OSS production.

Besides some much-reported benefits of this approach, using OSS products also presents new challenges. One such challenge is identifying relevant, high-quality OSS products among the hundreds of thousands that are available. One approach for doing that is to identify architectural patterns, since these patterns have a direct effect on a product's quality attributes, such as performance and reliability. However, there are no well-defined methods or tools available to identify architectural patterns.Research aim: Our goal is to identify approaches taken by novice software engineers that have no or little experience in identifying architectural patterns. We aim to get insight into how these novices tackle this problem, what challenges they encounter and what suggestions they have for improving this process.Method: We collected data from seven M. Sc. student teams that performed a pattern identification assignment. We conducted semi-structured interviews with eight students from two teams. We studied reflection reports from four teams that reported their experiences as part of their final report. Furthermore, during his M. Sc. course, one of the authors performed the assignment as a member of a team. We also included his experiences.Results and conclusions: We identified a number of approaches that students have taken in order to identify architectural patterns, as well as a number of challenges that they encountered in this task.

It is first argued that OSS should be considered a means to establish an industry regulation. The motivation of this first proposal is the need for harmonization of the supply chain in certain industrial sectors. The Air Traffic Management industry (ATM) is the only case considered in this paper. However, it is assumed that the regulatory advantage of OSS is not specific to that industry. The second proposal is about how to establish such a regulation through OSS. It is argued that the legal ownership of the OSS product should be assigned to a public organization, preferably to an organization that would be dedicated to monitor and promote the evolution of that product. The motivation for these proposals is based on the analysis of possible scenarios of OSS ownership in the case of ATM. Perspectives concerning the preliminary implementation of the proposals are introduced.","2010","2025-05-05 17:02:44","2025-05-05 17:02:44","","322-329","","NA","319","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: Int Federat Informat Proc Work Grp 2 13 ISBN: 978-3-642-13243-8 Place: NA Publisher: NA","","","","NA","","Agerfalk, P.; Boldyreff, C.; GonzalezBarahona, J.

In Open Source software development, users and developers are not so different. Anyhow, the diffusion of the Open Source software outside the development community contributes to sharpen the distinction among these two groups that are no longer equivalent. This circumstance has contributed to increase the interest on usability of Open Source software. Nevertheless, studies on end-users in Open Source contexts are still young.

We have collected data from the bug tracking systems of three OSS products, Mozilla Firefox, OpenSuse and OpenOffice.org. Our analysis aims at determining and discussing patterns of failure occurrences in the three OSS products to be used to predict reliability behaviour of future releases. Our findings indicate that in the three cases, failures occurrences follow a predetermined pattern, which shows: a) an initial stage in which the community learns the new version b) after this first period a rapid increase of the failure detection rate until c) very few failures are left and the discovery of a new failure discovery is rare.

Along these lines, the authors propose a particular reading of the political challenge that is Free Software from the standpoint of Hardt and Negri's (2000) theoretical work.

Dolores; Bueno, Salvador","ORGANIZATIONAL AND MOTIVATIONAL FACTORS FOR IMPLEMENTING ENTERPRISE SOLUTIONS BASED ON OPEN SOURCE SOFTWARE","RELATIONAL DATABASES AND OPEN-SOURCE SOFTWARE DEVELOPMENTS","","NA","NA","NA","Organizations implement Enterprise solutions, mainly Enterprise Resource Planning (ERP) systems, with the aim of attaining operational efficiency and the incorporation into new markets through the real time information flow control of the entire organization. However, ERP systems are complex tools, particularly for small and medium size enterprises (SMEs). For this reason, new ERP configurations have arisen, such as Open Source Software-ERP (OSS-ERP). In the website Sourceforge.net, we can identify 2058 projects about OSS-ERP, although all of them have not had an impact on the ERP market. This data is indicative of the increasing relevance of this enterprise solution for organizations. At this moment, the OSS-ERP vendors with a greater diffusion are Compiere, Openbravo, Abanq (previously FacturaLux), ERP5, Tiny ERP, Fisterra, OFBiz, SQL-Ledger and WebERP. OSS-ERP has three relevant advantages for organizations: (1) increased adaptability, (2) decreased reliance on a single supplier, (3) reduced costs. OSS-ERP generally include the necessary functions to integrally manage all the activities of a company. Due to their high flexibility, these tools can be adapted to the client's specific needs. Furthermore, as OSS-ERP are based on open software technologies, organizations do not have to pay licenses or exclusive contracts. With the collaboration of partners, OSS-ERP vendors receive benefits for the support services. Research in OSS has identified individual personal motives for using OSS software, analyzing specific OSS solutions, or the OSS movement itself. The literature in Enterprise solutions has also analyzed the main organizational factors for successfully implementing an ERP system. However, OSS-ERP is a research topic barely analyzed by the literature. This paper's aim is to specifically focus on the organizational and motivational factors for implementing OSS-ERP. The authors developed a research work for testing the impact of organizational and motivational factors on the implementation of OSS-ERP by means of a survey of organizations with OSS-ERP and OSS-ERP users.","2010","2025-05-05 17:02:45","2025-05-05 17:02:45","","257-273","","NA","NA","","","","Computer Science Technology and Applications","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-61668-436-5 Place: 400 OSER AVE, STE 1600, HAUPPAUGE, NY 11788-3635 USA Publisher: NOVA SCIENCE PUBLISHERS, INC","","","","NA","","Taylor, J.

Nevertheless, much of the academic research on OSS has focused on individual rather than organizational issues. Hence while there is some understanding of why individual developers and users opt for particular OSS applications, relatively little is known about the adoption of OSS as a software acquisition policy. This paper presents a study of 13 managers in the secondary software sector in Europe, and examines how their perceptions of the benefits and drawbacks of OSS affected their decision to adopt an open source policy for software in their companies. The study reveals how their perceptions of the business and technical benefits and drawbacks of OSS influenced the technological, organizational, environmental and individual factors considered within the adoption process. The findings reveal that many of these factors are similar to those reported by previous work on the adoption of innovation, leading us to conclude that organizational processes for the adoption of open innovation are reliant on the practices for closed innovation despite frequently cited loss of organizational control associated with open innovation.","2010-02","2025-05-05 17:02:46","2025-05-05 17:02:46","","76-95","","1","41","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article considers the dynamics of value creation fuelling the proliferation of OSS and examines the business model factors that enable value capture. After interviewing leaders from over 20 OSS firms and organisations through early 2006, we found that three factors were consistently important in defining a vendor's adoption of a given business model: software licence choice, which takes into account intellectual property ownership; management of developer communities; and the unique features of the markets and product categories in which the vendor participates. Considering these factors, we characterise seven business models. One striking finding is that it is rare to find business-model purity. The majority of firms in our sample are pursuing either blended business models or multiple models simultaneously.","2010","2025-05-05 17:02:46","2025-05-05 17:02:46","","432-456","","3-4","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Open source; Software; Open-source software; Business model; Intellectual property; Business models; 5240:Software & systems; Public domain; Value proposition; Technology: Comprehensive Works; 9130:Experimental/theoretical; 2310:Planning","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

South Africa is Botswana's neighbor and both countries are leading economies in Africa. Design/methodology/approach - The paper draws on a survey that was carried out in information communication technology (ICT)-intensive government ministries in Botswana in May 2008. The study sought to establish availability of policy framework, level of usage of open source software, government support, motivations for implementing open source software in government, availability of skills, attitude of it managers in government toward open source software and challenges of open source software deployment in the public sector. The population of the study consisted of information technology (IT) managers who were purposively selected from ICT-intensive government ministries and interviewed. The study was extended to cover South Africa through review of literature on the same issues as those studied in Botswana. Findings - Compared with other countries in developed and developing countries including South Africa, there is limited use of open source software in the public sector in Botswana. However, IT managers in government of Botswana demonstrate a positive attitude toward open source software, and seem to have adequate understanding of its potential benefits. Comparatively, South African government provides support for harnessing open source software; awareness among top government officials is high and attitude toward open source software seems positive; skills are generally available and hardly any challenges of using open source software were identified. Research limitations/implications - This study was limited to purposively selected government ministries which are ICT-intensive in Botswana, while for South Africa, the study was based on secondary sources of data and focused on deployment of open source software in government agencies. Practical implications - Despite the increasing deployment of open source software in government across the world, the Botswanan government is yet unlikely to put in place an enabling open source software policy to harness the potential of the Software. Originality/value - Open source software deployment in government across the world is gaining momentum purportedly to enhance universal access, reduce costs associated with commercial software bridge the digital divide, grow indigenous IT skills, etc. Botswana and South Africa are the economic frontline states in Africa, and their leadership role in this matter among counterparts on the African continent is pertinent.","2010","2025-05-05 17:02:46","2025-05-05 17:02:46","","63-80","","1","28","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Decision making; Information technology; Studies; Open source; Open-source software; Linux; Government; Africa; Local government; Open systems; Interoperability; Electronic government; South Africa; 5240:Software & systems; Public domain; Public sector; 9130:Experimental/theoretical; 1200:Social policy; Government agencies; Open standards; Cost control; Departments; Agreements; 9177:Africa; Botswana; Digital divide; Information society; Municipal government; Software deployment; Library And Information Sciences–Computer Applications","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We consider different aspects of openness in a corporate strategy for maintaining digital assets. An important aspect concerns activity and company influence in an Open Source tool-chain, another concerns support for data curation of digital assets actually offered by the tool chain.

These have been used as the basis to support the discovery of successful genetic modifications of the microbial metabolism to address industrial goals. However, the use of these methods has been restricted to bioinformaticians or other expert researchers. The main aim of this work is, therefore, to provide a user-friendly computational tool for Metabolic Engineering applications. Results: OptFlux is an open-source and modular software aimed at being the reference computational application in the field. It is the first tool to incorporate strain optimization tasks, i.e., the identification of Metabolic Engineering targets, using Evolutionary Algorithms/Simulated Annealing metaheuristics or the previously proposed OptKnock algorithm. It also allows the use of stoichiometric metabolic models for (i) phenotype simulation of both wild-type and mutant organisms, using the methods of Flux Balance Analysis, Minimization of Metabolic Adjustment or Regulatory on/off Minimization of Metabolic flux changes, (ii) Metabolic Flux Analysis, computing the admissible flux space given a set of measured fluxes, and (iii) pathway analysis through the calculation of Elementary Flux Modes. OptFlux also contemplates several methods for model simplification and other pre-processing operations aimed at reducing the search space for optimization algorithms. The software supports importing/exporting to several flat file formats and it is compatible with the SBML standard. OptFlux has a visualization module that allows the analysis of the model structure that is compatible with the layout information of Cell Designer, allowing the superimposition of simulation results with the model graph. Conclusions: The OptFlux software is freely available, together with documentation and other resources, thus bridging the gap from research in strain optimization algorithms and the final users. It is a valuable platform for researchers in the field that have available a number of useful tools. Its open-source nature invites contributions by all those interested in making their methods available for the community. Given its plug-in based architecture it can be extended with new functionalities. Currently, several plug-ins are being developed, including network topology analysis tools and the integration with Boolean network based regulatory models.","2010-04-19","2025-05-05 17:02:47","2025-05-05 17:02:47","","NA","","NA","4","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS projects have a culture built on volunteer participation to support software development. Computing degree programs desire to involve students in large-scale software projects to provide students with real-world experience and an understanding of the issues found in large, complex software projects. Involving computing students in OSS projects serves both the OSS community by providing development resources for the project while also serving the academic community by providing access to large software projects in which students can gain experience. However, the marriage of student and OSS project presents some challenges including identification of approachable OSS projects, creation of appropriate educational infrastructure, evaluation and grading, and more.

Our results indicate that FOSS project members possess rather sophisticated notions of software usability, which collectively mirror definitions commonly found in HCI textbooks. Our study also uncovered a wide range of practices that ultimately work to improve software usability. Importantly, these activities are typically based on close, direct interpersonal relationships between developers and their core users, a group of users who closely follow the project and provide high quality, respected feedback. These relationships, along with positive feedback from other users, generate social rewards that serve as the primary motivations for attending to usability issues on a day-to-day basis.

First, we have to model these signatures. In Lapierre et al. (2006), Lapierre et al. (2007) [3,4], we proposed an infrared (IR) ship signature simulation software (OSMOSIS) that can manage parametric emissivity. OSMOSIS comprises a smart computation time and memory management. Evaluating the effectiveness of an IR signature reduction method implies simulating the evolution of the IR signature with time. This requires a huge computation time. In this paper, we propose a novel hierarchical meshing strategy leading to an important reduction of the computation time. The time complexity of the algorithm is shown to be O(root N), where N is the requested number of facets of the mesh of the ship's surface. Then, we validate OSMOSIS on temperature measurements performed on an “L-shape” object. (C) 2009 Elsevier B.V.

Methods We used open source software to build a data management system and an internet application with a Flex client on a Java application server with a MySQL database backend. The application is hosted on Amazon Elastic Compute Cloud. This solution named Phynx supports data management, Web-based display of electronic patient information, and interactive review of patient-level information in the individual clinical context. This system was applied to a dataset from the UK General Practice Research Database (GPRD). Results Our solution can be setup and customized with limited programming resources, and there is almost no extra cost for software. Access times are short, the displayed information is structured in chronological order and visually attractive, and selected information such as drug exposure can be blinded. External experts can review patient profiles and save evaluations and comments via a common Web browser. Conclusions Phynx provides a flexible and economical solution for patient-level review of electronic medical information from databases considering the individual clinical context. It can therefore make an important contribution to an efficient validation of outcome assessment in drug safety database studies.

Materials and Methods: A structured questionnaire was randomly distributed to 500 dental hygienists and 500 dentists and a similar questionnaire was distributed to 1000 randomly selected individuals, divided equally into the following age groups: 15 to 20, 21 to 40, 41 to 60 and > 60 years. A clinical examination evaluating the ability to remove approximal dental plaque was also carried out in a total of 60 regular users of approximal cleaning aids. Plaque was scored before and after cleaning with a toothpick, dental floss or an interdental brush. Results: The response rate was 82%, 79% and 68% for the three groups. The results reveal that dental hygienists give more detailed information about a majority of the aspects that are related to the use of approximal cleaning aids compared with dentists (P < 0.01 or P < 0.001). The majority of the dental staff give recommendations to children and adolescents firstly to prevent dental caries and to older individuals to improve periodontal health. The use of different approximal cleaning aids on a daily basis varied with respect to age group (2% to 42%); dental floss dominated in the younger age groups and interdental brushes in the two oldest groups. In the clinical study, the largest plaque reduction was produced by the interdental brush (83%), followed by toothpicks (74%) and dental floss (73%).

Highspeed, high resolution imaging can reveal dynamic events such as changes in blood flow and responses to stimulation. Despite these benefits, commercially available scientific cameras rarely include software that is suitable for in-vivo imaging applications, making this highly versatile form of optical imaging challenging and time-consuming to implement. To address this issue, we have developed a novel, open-source software package to control high-speed, multispectral optical imaging systems. The software integrates a number of modular functions through a custom graphical user interface (GUI) and provides extensive control over a wide range of inexpensive IEEE 1394 Firewire cameras. Multispectral illumination can be incorporated through the use of off-the-shelf light emitting diodes which the software synchronizes to image acquisition via a programmed microcontroller, allowing arbitrary high-speed illumination sequences. The complete software suite is available for free download. Here we describe the software's framework and provide details to guide users with development of this and similar software.

While the benefits resulting from network externality have been examined in the related literature, the effect of free offer on the diffusion of new software has not been formally analyzed. We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters. Our methodology is shown to be applicable for both fixed and dynamic pricing strategies.

This paper, however, investigates the trajectories of two OSS-based information systems (IS) implementation projects in a developing country (DC) context with the aim to uncover the practice-based learning and resource sharing evident among locally situated and globally dispersed developers and users. The result of the interpretative case study research shows that the OSS philosophy and practice of software development, implementation and ownership, facilitates for the emergence of practice-based learning from the sharing of implementation accounts and artifacts without sharing the same context of work. Thus, the paper argues in favor of an implementation approach that focuses on distributed practice-based experience, knowledge and resource sharing, and learning with the mediation of the information infrastructure in order to facilitate and sustain OSS-based IS implementation in DCs. The paper contributes both to the OSS and IS implementation literatures by showing the mechanisms of developing the technological capacity of indigenous groups and using the trans-situated learning model as a means to understanding the learning dynamics in OSS implementation.","2010-12","2025-05-05 17:02:50","2025-05-05 17:02:50","","1-24","","1","2","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1000 CHASTAIN RD, KENNESAW, GA 30144 USA Publisher: KENNESAW STATE UNIV","","","","Open source software; capacity development; developing country; \n trans-situated learning","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This research explicates the interpretations and subsequent actions of key stakeholder groups towards OSS during the implementation of an OSS-based IS in a public sector organization in Ethiopia. Drawing upon the technological frames analytical framework, the study shows that the key stakeholder groups interpreted openness of the software and the community model of software implementation differently leading them to entertain divergent actions. Users were keen to solving operational problems via readymade IS with a third party support, while the management and technologists were focusing on the strategic importance of OSS not only to their own organization but also to the nation in general. Perception differences led to alliance formation, political processes, and change of management style. The study shows that as multiple interrelated elements shape the technological frames of groups, the relationship between frame incongruence and implementation is also complex and contextual. The study proposes technological frame analysis as an integral part of OSS implementation and a carefully crafted intervention to harness frame incongruence, if any.","2010-09","2025-05-05 17:02:50","2025-05-05 17:02:50","","NA","","1","43","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The metabotropic glutamate receptors (mGlus) belong to family C of the G-protein-coupled receptors (GPCRs). The eight mGlus identified to date are classified into three groups based on their structure, preferred signal transduction mechanisms, and pharmacology (group I: mGlu(1) and mGlus; group II: mGlu(2) and mGlu(3); group III: mGlu(4), mGlu(6), mGlu(7), and mGlu(8)). Noncompetitive antagonists, also known as negative allosteric modulators (NAMs), of mGlus offer potential therapeutic applications in diseases such as pain, anxiety, gastresophageal reflux disease (GERD), Parkinson's disease (PD), fragile X syndrome, and addiction. The development of structure activity relationships (SAR) in a (3-cyano-5-fluorophenyl)biaryl series using our functional cell-based assay is described in this communication. Further characterization of a selected compound, 3-fluoro-(5-(2-methylbenzo[d]thiazol-5-yl)benzonitrile, in additional cell based assays as well as in vitro assays designed to measure its metabolic stability and protein binding indicated its potential utility as an in vivo tool. Subsequent evaluation of the same compound in a pharmacokinetic study using intraperitoneal dosing in mice showed good exposure in both plasma and brain samples. The compound was efficacious in a mouse marble burying model of anxiety, an assay known to be sensitive to mGlus antagonists. A new operant model of addiction termed operant sensation seeking (OSS) was chosen as a second behavioral assay. The compound also proved efficacious in the OSS model and constitutes the first reported example of efficacy with a small molecule mGlu(5) NAM in this novel assay.","2011-08","2025-05-05 17:02:54","2025-05-05 17:02:54","","471-482","","8","2","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A hidden Markov model (HMM) is proposed that allows us to investigate (1) the extent to which individuals learn from their own experience and from interactions with peers, (2) whether an individual's ability to learn from these activities varies as she evolves/learns over time, and (3) to what extent individual learning persists over time. We calibrate the model based on six years of detailed data collected from 251 developers working on 25 OSS projects hosted at Sourceforge. Using the HMM, three latent learning states (high, medium, and low) are identified, and the marginal impact of learning activities on moving the developer between these states is estimated. Our findings reveal different patterns of learning in different learning states. Learning from peers appears to be the most important source of learning for developers across the three states. Developers in the medium learning state benefit the most through discussions that they initiate. On the other hand, developers in the low and the high states benefit the most by participating in discussions started by others. While in the low state, developers depend entirely upon their peers to learn, whereas in the medium or high state, they can also draw upon their own experiences. Explanations for these varying impacts of learning activities on the transitions of developers between the three learning states are provided. The HMM is shown to outperform the classical learning curve model. The HMM modeling of this study contributes to the development of a theoretically grounded understanding of learning behavior of individuals. Such a theory and associated findings have important managerial and operational implications for devising interventions to promote learning in a variety of settings.","2011-12","2025-05-05 17:02:54","2025-05-05 17:02:54","","790-807","","4","22","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, in the Eclipse open source software community, the main role of OSS development activities is taken over by companies. The relationship between individuals and companies is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of a company. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify a structure of co-creation in an OSS ecosystem led by companies considering the Eclipse community as one particular case.

This phenomenon is also known as “Inner Source”. While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. Objective: The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Method: Following an initial systematic literature review to generate seed category data constructs, we performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques. Results: We have identified a number of challenges and approaches to address them, and compared the findings to challenges related to development with OSS products reported in the literature. We found that many challenges identified in the case study could be mapped to challenges related to integration of OSS. Conclusion: The results provide important insights into common challenges of developing with OSS and Inner Source and may help organizations to understand how to improve their software development practices by adopting certain OSSD practices. The findings also identify the areas that need further research. (C) 2011 Elsevier B.V.

Chemical processes are invariably described by non-linear equations such as chemical reaction kinetics, flow-pressure relationships and physical properties. Dynamic simulation of such systems involves the solution of sets of non-linear differential and algebraic equations. There is also uncertainty associated with the model equations themselves (model uncertainty), their parameters (parametric uncertainty) and the inputs into the model (input uncertainty). Tools that aid chemical engineers in the solution of these problems have been successfully commercialised and enjoy a measure of success, although the adoption of dynamic and stochastic simulation packages is lagging behind the steady-state flowsheeting tools. Commercial software solutions can be prohibitively expensive in addition to confining users to adhere to proprietary standards. The Free Software and Open Source movements have made inroads into providing non-proprietary alternatives to many commercial software packages, which has encouraged the adoption of open standards. This work presents a framework for the development of stochastic dynamic simulations of chemical processes using only free and open source software. The large problem of stochastic dynamic simulation has been broken down into stages: 1. Input modelling using Markov chain models trained on process data or seeded by hand in addition to stationary distribution models. This enables dynamic scenarios to be handled with the minimum of special case code generation. 2. Process modelling using an object-oriented approach in the Modelica language. Modelica has an actively developed open source implementation called OpenModelica and is an open standard modelling language. 3. Monte Carlo simulation using extensions to the OpenModelica compiler that ease parallel simulations 4. Postprocessing, including visualisation and statistical analysis. Statistics that are generated can be used for control evaluation purposes. The Tennessee-Eastman challenge process is used to illustrate its capabilities.","2011","2025-05-05 17:02:55","2025-05-05 17:02:55","","146-150","","NA","29","","","","Computer-Aided Chemical Engineering","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-0-444-53895-6 Place: SARA BURGERHARTSTRAAT 25, PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS Publisher: ELSEVIER SCIENCE BV","","","","Open Source; Segmentation; stochastic modelling","","Pistikopoulos, E.

However, many other popular languages such as XSL or XML have received minor attention. In this paper, we discuss some trends in OSS development that we observed when considering multiple programming language evolution of OSS. Based on the revision data of 22 OSS projects, we tracked the evolution of language usage and other artefacts such as documentation files, binaries and graphics files. In these systems several different languages and artefact types including C/C++, Java, XML, XSL, Makefile, Groovy, HTML, Shell scripts, CSS, Graphics files, JavaScript, JSP, Ruby, Phyton, XQuery, OpenDocument files, PHP, etc. have been used. We found that the amount of code written in different languages differs substantially. Some of our findings can be summarized as follows: (1) JavaScript and CSS files most often co-evolve with XSL; (2) Most Java developers but only every second C/C++ developer work with XML; (3) and more generally, we observed a significant increase of usage of XML and XSL during recent years and found that Java or C are hardly ever the only language used by a developer. In fact, a developer works with more than 5 different artefact types (or 4 different languages) in a project on average.","2011","2025-05-05 17:02:55","2025-05-05 17:02:55","","13–22","","NA","NA","","","","MSR '11","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450305747 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software; evolution; programming language; software archives","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there has been little focus on developing valid frameworks that enable critical evaluation and common understanding of factors influencing OSS adoption. This paper seeks to address this shortcoming by presenting a theory-grounded framework for exploring these factors and explaining their influence on OSS adoption, with the context of study being small- to medium-sized Information Technology (IT) businesses in the U.K. The framework has implications for this type of business and, we will suggest, more widely as a frame of reference for understanding, and as tool for evaluating benefits and challenges in, OSS adoption. It also offers researchers a structured way of investigating adoption issues and a base from which to develop models of OSS adoption. The study reported in this paper used the Decomposed Theory of Planned Behaviour (DTPB) as a basis for the research propositions, with the aim of: (i) developing a framework of empirical factors that influence OSS adoption; and (ii) appraising it through case study evaluation with 10 U.K. Small- to medium-sized enterprises in the IT sector. The demonstration of the capabilities of the framework suggests that it is able to provide a reliable explanation of the complex and subjective factors that influence attitudes, subjective norms and control over the use of OSS. The paper further argues that the DTPB proved useful in this research area and that it can provide a variety of situation-specific insights related to factors that influence the adoption of OSS.

This article argues that China now needs a different voice against the IPR dogma and should make a contribution to the international effort against intellectual monopoly, and the software industry could be where to start. On one hand, China should take further measures to promote the development of free/open source software. On the other hand, China needs to scrutinize and reform relevant economic and legal systems and adjust strategy for international negotiations, strengthening antitrust enforcement against software monopoly and taking a tough stance against software patents in international community.","2011","2025-05-05 17:02:55","2025-05-05 17:02:55","","290-306","","2","2","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Monopolies; Philosophy; China; Studies; Open source; Copyright; Linux; Operating systems; Intellectual property; Free software; Power; 9130:Experiment/theoretical treatment; Public domain; 9179:Asia & the Pacific; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; Proprietary; 1130:Economic theory; Free; Antitrust; Monopoly; Business And Economics–Economic Systems And Theories; Economic History","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments. The final results consisted of a set of key adoption opportunities that aimed to improve software quality and overall development productivity by importing best practices from the FLOSS environment. The adoption opportunities were then validated at three large corporations.","2011-01","2025-05-05 17:02:56","2025-05-05 17:02:56","","88-122","","1","12","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS","","","","Open source software; Advantages; Information systems; Studies; Open source; Software; Open-source software; Linux; Methods; Models; Software development; Software quality; 9130:Experiment/theoretical treatment; Public domain; 51321:Software Publishers; Software industry; Industrial development; Industrialisation; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In an earlier article, a proof-of-concept for a computer-aided visualization tool (also named STEVE, version 1.0) for stochastic theory education in water resources engineering was articulated [see, Schwenk et al. Comput. Appl. Eng. Educ., 2008, in press). Using lava Native Interfacing, it was shown that STEVE 1.0 could wrap a space time stochastic model written in any computer language and be independent of any specific language compiler during tool usage. This article describes the general philosophy, software design, and classroom usage for STEVE with significant improvements on visualization and user-friendliness (hence, rightfully called version 2.0). The software was created using the C++ programming language with the Microsoft Windows Applications Programming Interface (API). OpenGL was used for the visualization display, and the OpenGL Utility Toolkit (GLUT) was used to visualize text inside the OpenGL window. The instructor-specified simulation program on stochastic theory was written in Fortran 77. The application has user-friendly options for modifying input data and parameter specifications as desired by the instructor or the student user. STEVE 2.0 has been tested with the Windows XP and Windows Vista operating systems. For the benefit of interested users and software makers, we also provide the software application, a short tutorial and all pertinent source codes as freeware for download on our STEVE homepage at http://iweb.tntech.edu/saswe/steve.html.

The models capture numerous important characteristics of inpatient obstetrical patient flow such as time of day and day of week dependent arrivals and length of stay, multiple patient types and clinical interventions, and multiple patient care units with inter-unit patient transfers. We have used these models in several projects at different hospitals involving design of procedure scheduling templates and analysis of inpatient obstetrical capacity.

As an example the coordinated voltage control of an Under-Load Tap Changer (ULTC) is implemented as IEC 61499 control application in the 4DIAC framework and the ULTC model together with a model of the distribution network are simulated in the GNU Octave/PSAT environment.","2011","2025-05-05 17:02:57","2025-05-05 17:02:57","","NA","","NA","NA","","","","IEEE Power and Energy Society General Meeting PESGM","","","","","","NA","","","","","","","Backup Publisher: IEEE Power & Energy Soc (PES); IEEE ISBN: 978-1-4577-1001-8 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

ChemT automatically generates three-dimensional chemical libraries by inputting a chemical template and the functional groups of interest. The graphical user interface of ChemT is self-explanatory, and a complete tutorial is provided. Several file formats are accepted by ChemT, and it is possible to filter the generated compounds according to different physicochemical properties. The compounds can be subject to force field minimization, and the resulting three-dimensional structures recorded on commonly used file formats. ChemT may be a valuable tool for investigators interested in using in silico virtual screening tools, such as quantitative structure-activity relationship modelling or molecular docking, in order to prioritize compounds for further chemical synthesis.

We examined 12 FOSS projects: 4 small, 4 medium and 4 large, where size was determined by number of code contributors. First, we found that contrary to what has been reported from studies of individual large projects like Mozilla and Eclipse, duplicate bug reports are a problem for FOSS projects, especially medium-sized, which struggle with a large number of submissions without the resources of large projects. Second, we found that the focus of a project does not affect the number of duplicate bug reports.

According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at SourceForge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects.

With dual licensing, a firm releases the same software product under both a traditional proprietary license and an open source one. We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of “going open source” and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

Furthermore, in order to structure different approaches, a project's history is equally of importance in terms of whether a project was initiated by a firm or a community.

However, the programmers may work more or less on these projects than what is best for the firms. To manage the programmers' efforts, the firms set appropriate employment policies and incentives. These policies and career concerns then together govern the programmers' effort allocation between the open-source and proprietary projects. We examine this relationship using a variant of the principal/agent model. We derive and characterize optimal employment contracts and show that firms either offer a bonus for only one of the two projects or do not offer any bonuses.

The study investigates factors that affect the selection of software for public sector information systems with, an emphasis on how Free and Open Source Software ( FOSS) is used and could be used in such projects. The objectives of the study are as follows. The study aims to identify factors that affect the adoption of Software in Sri Lankan government sector projects. In addition to this it identifies features that are considered as important in such large Information Systems, and how they relate to Open Source Software adoption in the context of the public sector in Sri Lanka. The findings are analyzed and suitable recommendations are presented for better selection of software in the public sector. The work is important as it identifies and highlights factors that affect the choice of software in the public sector. This is important for several categories of people. It is of importance to the strategic management and policy makers to know what drives the information system procurement decisions in order to make more relevant policies and guidelines that are congruent with the needs in government sector departments. It is useful when advocating new technologies and information systems. This is especially true when advocating the use of Free and Open Source software for the use in the public sector in a wholesome and sustainable manner. The research is also important to software vendors and solution providers to the public sector in identifying what factors need to be taken in to account when bidding for public sector IS projects. The research is of a qualitative nature. It consists of multiple case studies of selected government sector departments and projects in Sri Lanka. The study investigates information systems developed by internal staff, developed by external consultants, procured systems, system implementation via private public partnerships (PPP) and projects guided by the Information and Communication Technology Agency (ICTA) of Sri Lanka. Data was gathered through interviews of staff at different levels of selected government sector Information Systems projects. The data was comparatively analyzed on a case by case basis to identify common patterns and trends among the investigated organizations and projects. The identified factors affecting the choice of software include the cost, technical specifications, bidder's expertise in selected technology and user's expertise in selected technology amongst other factors described in the full paper. The study identifies patterns between the choice of software - FOSS or non FOSS, and these identified factors. Based on these, recommendations are given to adopt and benefit from the use of FOSS in public sector enterprise level software projects.","2011","2025-05-05 17:03:00","2025-05-05 17:03:00","","239-252","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-906638-97-9 Place: CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND Publisher: ACAD CONFERENCES LTD","","","","open source software; government; enterprise software; free; software\n adoption","","Grant, K.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

But the argument for free software derives its true normative weight from social justice considerations: the evaluation of the basis for a software economy should be guided by consideration of the social and cultural states which are the ultimate goals of any economic arrangement.

In so doing, the initial goals of free software advocates are being dramatically expanded to include broader aims of digital freedom and social justice. Utilizing the concept of social movements from political sociology, this article first outlines the key aims and discourses surrounding the free software movement by discussing the emergence and development of F/OSS efforts such as the GNU/Linux operating system and the GNU Public License (GPL). Second, I provide examples of how the free software discourses have been adopted, altered, and expanded by a number of organized groups over the past decade. These groups, such as the Creative Commons, digital privacy advocates, and global development agencies, have adopted some of the core concepts of free software, while greatly expanding their meaning and purpose to suit their own advocacy aims. Finally, I argue that the adoption of free software discourse among these newer groups is also having a recursive effect upon the free software movement by encouraging free software advocates to conceptualize F/OSS as part of a broader movement of digital rights and social justice. In the conclusion, the prospects for the emergence of a larger technological and cultural freedom movement in the future are assessed.","2011","2025-05-05 17:03:00","2025-05-05 17:03:00","","223-239","","3, SI","8","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this reason, scanner manufacturers provide researchers with programming frameworks that give full control over the whole procedure. The drawback is that these environments are complex, and the code is non-portable and covered by non-disclosure agreements. In this article, a simplified framework based on a free scripting language (Lua) is presented. It is oriented to the development of postprocessing algorithms that are seamlessly integrated with the pipeline of a commercial scanner. The structure privileges simplicity over performance, to be quickly learned and used by researchers and students who might not be acquainted with low-level programming languages. Common postprocessing algorithms (contrast modulation, pixelwise fitting, phase-contrast imaging) could be implemented with similar to 100 logical lines of code or less, using a syntax that is similar to the Matlab programming language. The average performance of the reconstruction was lower with respect to the native implementation, but superior to offline postprocessing on a desktop computer, without the bottleneck of offline data export.

Many OSS projects are composed of a mix group of firm-paid and volunteer developers, with different motivations, collaboration practices and working styles. As OSS development consists of collaborative works in nature, it is important to know whether these differences have an impact on collaboration between difference types of stakeholders, which lead to an influence in the project outcomes. In this paper, we empirically investigate the firm-paid participation in resolving OSS evolution issues, the stakeholder collaboration and its impact on OSS issue resolution time. The results suggest that though a firm-paid assigned developer resolves much more issues than a volunteer developer does, there is no difference in issue resolution time between them. Besides, the more important factor that influences the issue resolution time comes from the collaboration among stakeholders rather than from individual characteristics.","2011","2025-05-05 17:03:01","2025-05-05 17:03:01","","1+","","NA","365","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: CAPES, Minist Educ, Coordinat Improvement Higher Educ Personnel; CNPQ,\n Minist Sci & Tecnol, Natl Council Sci & Technol Dev; FAPESB, State\n Bahia Res Agcy; Petrobras ISBN: 978-3-642-24418-6; 978-3-642-24417-9 Place: NA Publisher: NA","","","","NA","","Hissam, S.

This study aims to use case study research to increase the understanding of the public sectors' low adoption rate and the factors that impact the intentions to adopt an OSS ERP system. The results indicate that the system's functionality is essential; OSS ERP systems are not perceived as fully developed for large organizations such as municipalities.

Different approaches for introducing usability activities into SW development have not yet been evaluated with respect to open source software (OSS). This paper tests the introduction of usability activities through four empirical case studies in the OSS development context. Case studies were carried out using four OSS projects that were not commercially supported. Empirical analysis suggests that usability specialists should become members of the OSS community, but, at the same time, should keep an objective view. The usability activities had substantially more impact when specialists introduced and carried them out as fellow members of the OSS community than as usability consultants from outside the community. The importance of management commitment for usability activities is discussed in the OSS context. The challenge of adapting usability and OSS development philosophies together should be researched further.

It is therefore important to understand how and why potential contributors fail in the process of transitioning from user to contributor. Most newcomers, or ""newbies"", have their first interaction with a community through a mailing list. To understand how this first contact influences future interactions, we studied eight mailing lists across four FOSS projects: MediaWiki, GIMP, PostgreSQL, and Subversion. We analyzed discussions initiated by newbies to determine the effect of gender, nationality, politeness, helpfulness and timeliness of response. We found that nearly 80% of newbie posts received replies, and that receiving timely responses, especially within 48 hours, was positively correlated with future participation.

For example, the Ministry of Popular Power for Internal Relations and Justice, through the Autonomous Service of Registries and Notaries and the emission of decrees and laws that govern the corresponding competence, such as Presidential Decree 3.390 (Presidency of the Republic, 2004), has implemented modernization through the automation of registry and notary processes by employing electronic means in which free software has a place. Interest has arisen in establishing an effective legal application for the public function developed by Registries and Notaries by implementing such an IT migration.

This software metrics is formulated by analyzing modularity traits such as size, complexity, cohesion, and coupling of 59 Java-based OSS Projects from sourceforge. net using SONAR tool. These OSS Projects are selected since they have been downloaded more than 100K times and believed to have the required modularity trait to be successful. The software metrics related to modularity in class, package and system level of these projects are extracted and analyzed. The similarities found are then analyzed to determine the class quality, package quality, and then combined with system architecture measure to formulate the Modularity Index.

To learn some lessons from successful OSS in handling the complexity, social network analysis is prevalent in analyzing both human-aspect and source-code-aspect interaction of OSS. This paper conducted an empirical study of an OSS project-ArgoUML. Unlike most previous studies regarding OSS email archives as a whole social network, our focus is on the quantitative analysis of a series of social networks produced in the process of OSS version evolution and module development.Through the empirical study, we have found that all the social network measures employed in this study are comparable to identify core developers of ArgoUML project. The frequency of co-occurrence of developers within the same topic is not a decisive factor to identify core developers. Developers within the same module communicate closely and frequently with each other. The more modules a developer developed, the more communication he (or she) will have with other developers. Although participants of developers' mailing lists are fluctuating in a large magnitude, the committers of the source code are kept stable in each version evolution. Moreover, the variation of committers of source code in version evolutions is almost unpredictable based on the variation of participants in developers' mailing lists.","2011","2025-05-05 17:03:03","2025-05-05 17:03:03","","71–80","","NA","NA","","","","IWPSE-EVOL '11","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450308489 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","social network; open source; module community; version evolution","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It draws on a study of online observation of a virtual community, i.e. an open source software (OSS) community. The paper examines general and specific advantages and disadvantages of the observer roles in online settings by relating these roles to the same roles assumed in offline settings. The study suggests that under the right circumstances online and offline observation may benefit from being combined as they complement each other well. Quality issues and factors important to elicit trustworthy observational data from online study settings, such as OSS communities, are discussed. A proposition is made concerning how threats to credibility and transferability in relation to online observation (i.e. lack of richness and detail, risk of misunderstandings) can be diminished, while maintaining the level of dependability (which is potentially high due to a greater degree of anonymity and ""isolation"" in online settings). The paper thus suggests that the less participative the researcher's online observer role is, the more s/he should consider introducing offline data collection techniques rather than adopting a more participative role in the observed online setting. This methodological discussion forms the basis for making a well-considered choice of online observer role rather than passively sliding into a role assigned by the setting.

More recently, software evolution researchers have investigated logical dependencies between artifacts to assess failure-proneness, detect design issues, infer code decay, and predict likely changes. However, the interplay between these two kinds of dependencies is still obscure. By mining 150 thousand commits from the Apache Software Foundation repository and employing object-oriented metrics reference values, we concluded that 91% of all established logical dependencies involve non-structurally related artifacts. Furthermore, we found some evidence that structural dependencies do not lead to logical dependencies in most situations. These results suggest that dependency management methods and tools should rely on both kinds of dependencies, since they represent different dimensions of software evolvability.","2011","2025-05-05 17:03:03","2025-05-05 17:03:03","","144–153","","NA","NA","","","","SBES '11","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9780769546032 Place: USA Publisher: IEEE Computer Society","","","","software evolution; mining software repositories; dependency management; logical coupling; logical dependencies; structural analysis; structural coupling; structural dependencies","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The focus for our case study is on assessing the health of the ecosystems for the two investigated Open Source projects by means of quantitative analysis of publically available data sources about Open Source projects. The health of ecosystems is an important prerequisite for a long term sustainable OSS (Open Source Software) tool-chain in the MDD area, which can aid strategic decision making for potential adoption within a company context. We have established details on the extent to which developers and users are active in two specific OSS ecosystems, and identified organisational influence for both ecosystems.

Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. Methods: This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Observations: Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Conclusion: Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future. The impact of these new technologies is particularly effective in image communication, PACS and teleradiology. (C) 2010 Elsevier Ireland Ltd.

We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software.

The software currently calculates 797 descriptors (663 1D, 2D descriptors, and 134 3D descriptors) and 10 types of fingerprints. These descriptors and fingerprints are calculated mainly using The Chemistry Development Kit. Some additional descriptors and fingerprints were added, which include atom type electrotopological state descriptors, McGowan volume, molecular linear free energy relation descriptors, ring counts, count of chemical substructures identified by Laggner, and binary fingerprints and count of chemical substructures identified by Klekota and Roth. Methods: PaDEL-Descriptor was developed using the Java language and consists of a library component and an interface component. The library component allows it to be easily integrated into quantitative structure activity relationship software to provide the descriptor calculation feature while the interface component allows it to be used as a standalone software. The software uses a Master/Worker pattern to take advantage of the multiple CPU cores that are present in most modern computers to speed up calculations of molecular descriptors. Results: The software has several advantages over existing standalone molecular descriptor calculation software. It is free and open source, has both graphical user interface and command line interfaces, can work on all major platforms (Windows, Linux, MacOS), supports more than 90 different molecular file formats, and is multithreaded. Conclusion: PaDEL-Descriptor is a useful addition to the currently available molecular descriptor calculation software.

User participation is becoming a relevant topic of research in the OSS development context. Though it has not been examined much to date, the OSS development context has been argued to advocate a particular type of participatory design, which can now be scrutinised in its natural setting as it evolves. Two interpretive case studies on user participation in OSS development are included in this article. The first examines a traditional community OSS development project; the second concentrates on the company OSS development context, the case being a software development unit of a global corporation involved in OSS development. Through analysis of the cases, different forms of participatory design (PD), especially of distributed PD, are identified. Distributed PD is interpreted to include gaining an understanding of users' current practices, redesigning them together with users and gathering feedback from users related to the solutions. Different kinds of roles are available to users, as well as to for intermediaries `representing users'. Especially, the importance of online forum-based and intermediary-driven PD is emphasised in this article. Implications for PD and OSS research and practice are considered.","2011","2025-05-05 17:03:05","2025-05-05 17:03:05","","309-323","","3","30","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The data is analyzed with multiple Data Mining techniques. Initially three competing models are created using Logistic Regression, Decision Trees and Neural Networks. These models are compared for precision and are refined in several phases. Text Mining is used to create new variables that improve the predictive power of the models. The final model is chosen based on best fit to separate training and validation data sets and the ability to explain the relationship among variables. Model robustness is determined by testing it on a new dataset extracted from the SF repository. The results indicate that end-user involvement, project age, functionality, usage, project management techniques, project type and team communication methods have a significant impact on the development of OSS projects.","2011-12","2025-05-05 17:03:05","2025-05-05 17:03:05","","27-48","","4","2","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 701 E CHOCOLATE AVE, STE 200, HERSHEY, PA 17033-1240 USA Publisher: IGI GLOBAL","","","","Software Development; Open Source Software; Data Mining; Data Models; Decision Trees; Logistic Regression; Neural\n Networks","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities.

Our software market is a system where each agent is independent of each other in the choice about buying or selling software products or services. The proposed work aims to analyze the influence of FLOSS firms producing both software and services in vertical software markets, nowadays mostly dominated by large proprietary firms. The findings show that FLOSS firms are able to compete with proprietary firms, though in the end a monopoly or oligopoly of the latters emerges.

On one hand, most FOSS systems are based on very fine-grained units of software deployment - called packages - which promote system evolution; on the other hand, FOSS systems are among the largest software systems known and require sophisticated static and dynamic conditions to be verified, in order to successfully deploy upgrades on users' machines. The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V.

In order to support the proposed model, prototype called myIntegration is implemented based on OpenSyncro. OpenSyncro is an open source software (OSS) meant for Enterprise Application Integration (EAI). The Testing Phase was carried out by taking into account the actual test scenario involving the Department A (owner of the Malaysian Personal Record) and Department B (Human Resources Manager of Malaysian Civil Servants). Tests conducted have shown that the exchange of information between the Department A and B have been successfully realized. The finding from this research, where a new integration model has been created, can be referred by any government or private organizations in developing their systems integration facilities. The model also besides reducing the requirement of hardware; also reduces the dependency to proprietary products. In addition, the prototype developed, which based on OpenSyncro is capable in providing an alternative solution to the IT community to anchor any systems integration project at a lower cost and in a user friendly environment.","2011","2025-05-05 17:03:06","2025-05-05 17:03:06","","13-18","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-908272-12-6 Place: CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND Publisher: ACAD CONFERENCES LTD","","","","Enterprise Application Integration (EAI); integration model; middleware solution; system integration; open source\n software","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This in turn is influenced by three types of social capital - relational capital, cognitive capital and structural capital. In addition, this study also examines two moderating effects - the impact of technical complexity on the relationship between cognitive capital and expertise integration, and of task interdependence on the relationship between expertise integration and task completion. Through a field survey of 160 OSS members from five Taiwanese communities, there is support for some of the proposed hypotheses. Both reciprocity and centrality affect expertise integration as expected, but the influence of commitment and cognitive capital (including expertise and tenure) on expertise integration is not significant. Finally, expertise integration affects both team size and team effort, which in turn jointly influence task completion.

It would be useful to understand how to get such a project to accept a process improvement proposal and hence to perform process innovation. We want to determine an effective and feasible qualitative research method for studying the above question. We present (narratively) a case study of how we worked towards and eventually found such a research method. The case involves four attempts at collecting suitable data about innovation episodes (direct participation (twice), polling developers for episodes, manually finding episodes in mailing list archives) and the adaptation of the Grounded Theory data analysis methodology. Direct participation allows gathering rather rich data, but does not allow for observing a sufficiently large number of innovation episodes. Polling developers for episodes did not prove to be useful. Using mailing list archives to find data to be analyzed is both feasible and effective. We also describe how the data thus found can be analyzed based on the Grounded Theory Method with suitable adjustments. By-and-large, our findings ought to apply to studying various phenomena in OSS development processes that are similarly heavyweight and infrequent. However, specific details may block this possibility and we cannot predict which details that might be. The amount of effort involved in direct participation approaches to qualitative research can easily be underestimated. Also, survey approaches are not well-suited for many process issues in OSS, because too few developers are sufficiently process-conscious. An approach based on passive observation is a viable alternative in the OSS context due to the availability of large amounts of fairly complete archival data.","2011-08","2025-05-05 17:03:07","2025-05-05 17:03:07","","514-537","","4, SI","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Drawing on document-centric approaches we hypothesize that documents supporting asymmetric groups are likely to be more prescriptive and explicate their own use compared to documents supporting symmetric groups. Through exploratory analysis of two kinds of documents, used across three FLOSS projects, we find that documents supporting collaborators with asymmetric knowledge do appear to explicate their own use in more detail. They do so by prescribing their own 1) purpose, 2) context of use, 3) content and form in greater detail than documents used by core community members with symmetric access to project knowledge.","2011","2025-05-05 17:03:09","2025-05-05 17:03:09","","1–10","","NA","NA","","","","HICSS '11","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9780769542829 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within the context of a knowledge-based economy, this sort of approach appears exemplary for a growing number of industrial activities in which the amount of knowledge that has to be mastered is too large for a single agent, however powerful. Considering knowledge as a mutual resource requires a rethinking of the value chain concept, since cash flow is derived from use of the knowledge base (services, complementary products), not from the knowledge itself. In a classical industrial economics perspective, this reshaping of the value chain must be analyzed not only at the global ecosystem level (who produces what, between firms and universities, users and producers, etc.), but also at the industrial level (once the industry's role has been identified, how does it organize itself?). In this article, we argue for a more structured and global analysis, based on the tools of industrial economics, and thus starting from the basic conditions of the computer market and of the buyers' competence in software development (the ""dominant user's skill"").","2011","2025-05-05 17:03:09","2025-05-05 17:03:09","","39–64","","136","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Information technology; Open-source software; Competition; Operating systems; Economics; open-source software; Software development; Organizational behavior; Computer industry; 5240:Software & systems; 2500:Organizational behavior; 9175:Western Europe; Industrial economics; Value chain; 1130:Economic theory; Competitive advantage; Free; Floss; France; Computer based modeling; Expert systems; Generic products; Industrial organization; Knowledge base; 33411:Computer; Peripheral Equipment Manufacturing; Business And Economics–Production of Goods And Services","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our analysis suggests that a serious analysis of the rationality, motivations and consequences of such public interventions involves a careful examination of the various roles of the public powers and the various categories of software involved. We provide empirical evidence that FOSS support is stronger in countries (i) where e-government services are more largely available, and (ii) where the domestic software industry is lagging behind.

This results in the need for constant adaptation and expansion of OSS/BSS1 used in mobile operator networks. Currently, adaptation and expansion strategies are poorly formalized and validated. In current state-of-the-art approaches, several iterations involving analysts and system architects are necessary, resulting in time and money consuming service development. The workflow design method proposed in this paper fills this gap. It employs a well-defined workflow and analysis model for developing and adapting OSS/BSS. The applicability of this novel approach is confirmed by a prototypically implemented design software tool which has been tested in a telecommunication enterprise. The developed tool provides automation of service planning, computational independent workflow design and its transformation into its realization model. The reduction of development time and thus necessary financial input has been proven based on our real-world experiments.","2012","2025-05-05 17:03:10","2025-05-05 17:03:10","","142-152","","NA","117","","","","Lecture Notes in Business Information Processing","","","","","","NA","","","","","","","Backup Publisher: Vilnius Univ, Kaunas Fac Humanities, Dept Informat; Poznan Univ Econ,\n Dept Informat Syst ISBN: 978-3-642-30359-3; 978-3-642-30358-6 Place: NA Publisher: NA","","","","NA","","Abramowicz, W.; Kriksciuniene, D.; Sakalauskas, V.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Due to the complexity of the problem and the high number of SNA features that can be extracted, this paper proposes a genetic search of an optimum subset of indicators leading to a group of latent patterns of behaviour maximizing the explained data variance and the interpretation of factors.

In this paper, I use evidence from the United States and Canada to examine the distribution of these benefits and costs. I argue that although the rhetoric surrounding OSS is supported empirically, the benefits of OSS have been limited because of the way this technological project has evolved within its associated policy environment. That is, although ostensibly neutral, the policies and laws of both the U.S. and Canadian governments have tended to be positioned implicitly against the use of OSS both in the public sector and in the economy generally. In addition, OSS use and development requires a set of skills that are absent in many instances or create prohibitively high costs. Thus OSS is typically used by larger organizations, and its development is restricted to a mostly male, highly educated, high-income group of contributors. Therefore while the benefits of OSS are real, the distribution of these benefits is skewed. (C) 2011 Elsevier Inc.

Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of vendors. In other words, management of co-creation and competition are being conducted at the same time.

First, they founded the Coordination of Information (COI) and subsequently, the Office of Strategic Services - OSS), naming General William Donovan as head of both. Right from the establishment of OSS, Donovan wanted to expand its operations to North African and Mediterranean battlefields in order for the American intelligence service to be able to direct special operations against the Axis Powers in Yugoslavia from there. The setting up of the bases required a considerable amount of effort and negotiation with the British secret services, as they were used to defending their own interests and leading intelligence position in the Balkans and would not permit the OSS to operate independently in Yugoslavia. Donovan thus established bases in Cairo and Bari, with a Yugoslav section operating within each. The principal tasks of the two sections were to train the personnel to be sent to Yugoslavia, to gather intelligence about Yugoslavia, organise assistance and support for Yugoslav resistance movements and compile intelligence obtained by the OSS from its missions from the occupied Yugoslav territory. Aided initially by the government in exile and later on by Partisan representatives in southern Italy, the Yugoslav sections trained numerous Yugoslays many of who were Slovenes and sent them back to Yugoslavia. These worked as wireless operators, cryptographers and interpreters mostly between Slovene and Croatian Partisans. Some Slovenes, American Slovenes in particular, carried out the functions of mission chiefs or instructors in the Yugoslav sections of the OSS. Although collaborators with the American intelligence service made important contribution to the common struggle against the Axis Powers, they were branded by the Partisan leadership towards the end of the war and after it for having worked with the Americans. Following the Tehran Conference in December 1943, the supply of aid for the resistance movements was directed to support the Partisan movement. Towards the end of the war and with the growth of the National Liberation Movement (NOG) in Yugoslavia, the role of the Yugoslav section gradually diminished It can be concluded that the activities of the Yugoslav sections in Cairo and Bari significantly influenced the development of resistance movements in Yugoslavia and Slovenia, both in terms of organising aid as well as training and sending the American missions to Yugoslavia.","2012","2025-05-05 17:03:11","2025-05-05 17:03:11","","809-826","","4","20","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Models used in open software development are innovative in several ways, to the point that they are only recognized as valid models at all since they have actually produced mature and stable software more in a swift fashion. Some studies attempt to answer the OSS's development model, way to produce the quality products and distributed development model driven by motivated voluntary developers found in OSS. However, they are usually focused on handful projects and often miss to represent the whole world of OSS development. We analyze FLOSSMetrics database and SourceForge repository. By examining these, we attempt to identify 1) factual landscape of OSS projects, 2) correlation between different measures including developers' activities and consumers' interests. This analysis is also supplemented by empirical research on world re-known OSS projects to identify the implication of vendor-led OSS projects. We find that OSS projects are hardly to be seen as loci of future open innovation in several ways.

They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.","2012","2025-05-05 17:03:11","2025-05-05 17:03:11","","156-187","","2","25","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD","","","","Open source; Diffusion; Case studies; Adoption; Diffusion theory; Public sector organizations; Open\n source software","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It has received considerable attention in the scientific literature, but mostly in the professional press. In fact, there is much debate over its actual commercial and organizational value. Since the public discourse accompanying an IT may influence adoption decisions, it is important to consider IT specialists' perceptions of the discourse on OSS. In this study, we investigated the relationship between IT specialists' profiles, IT specialists' reception of the public discourse on OSS, and their organizations' receptivity to OSS. Drawing on the socio-cognitive perspective of IT innovation adoption and the organizing vision theory, a survey of 271 IT specialists was conducted to examine these issues. Our results indicate that a majority of IT specialists in our sample are rather neutral about the OSS concept conveyed in the public discourse. However, our sample also comprises respondents with more extreme perceptions who can be classified as either supporters or detractors. Our results indicate that detractors have more years of experience but have been less exposed to OSS than supporters, and that IT specialists' perceptions of the OSS concept are positively associated with their organizations' openness to OSS adoption and, to a lesser extent, with the existence of an organizational policy that favors OSS adoption. Altogether, our findings provide strong support for the organizing vision theory and the idea that the popularity of an IT innovation concept favors the adoption of the material IT innovation in organizations. By providing a preliminary test of a nomological network of IT specialists' perceptions of the OSS concept, our study offers insights as to why organizations may or may not take OSS into account in their software procurement decisions.

Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.","2012-12","2025-05-05 17:03:12","2025-05-05 17:03:12","","28-36","","12","2","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES","","","","Open source software; Research methodology; Business And Economics; Marketing; Open source; open source software; Participation; Open-source software; Research; Competition; Customers; Business model; Business models; Public domain; Literature reviews; Value creation; Value proposition; Competitive advantage; Customer satisfaction; Perceptions; Cost control; Profits; Willingness to pay; Market strategy; Suppliers; business models; Business value; customer value creation; enterprise customers; marketing strategy; open source suppliers","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A paradigm of open source project where code quality is especially important is the scientific language R. This paper aims to perform measurements on the R statistical open source software, examine the relationships among the observed metrics and special attributes of the R software and search for certain characteristics that define its behavior and structure. For this purpose, a random sample of 508 R packages has been downloaded from the CRAN repository of R and has been measured, using the SourceMonitor metrics tool. The resulted measurements, along with a significant number of specific attributes of the R packages, were examined and analyzed, leading to interesting conclusions such as the validity of a power law distribution regarding the majority of the sample's metrics and the absence of specific patterns due to the interdependencies among packages.

On the other hand, many free solutions with comparable functionalities are developed, which have been increasingly successful. In this article, we test different associations of software to make a comparison between free software and market solutions. In this experiment, 24 students in a Master's Degree course aimed to design mechanical products by using software to assist collaborative distributed design, using two different configurations. This experiment allowed us to compare design functionalities between free and commercial solutions, in order to determine ways to improve efficiency in a collaborative distributed design situation.

It shows revenue generation factor, cost efficiency factor and growth factor to have a positive influence on the OSS of Indian MFIs. Adjusted impairment loan loss allowance ratio, a portfolio risk factor and average loan size per borrower, a development factor, are seen to have a negative influence on OSS of Indian MFIs. The results thus infer five significant factors that Indian MFI managers must concentrate on to enhance the OSS of their organizations. The authors then discuss how mismanaging these five factors can deviate an MFI from its social goal of poverty alleviation. The crisis in Indian microfinance industry is explored to unveil the dangers involved in mismanagement of these factors. The paper concludes by stating that it is imperative for Indian MFI managers to introspect about their lending and recovery practices, so as to ensure that they manage the factors affecting their OSS, without exploiting the poor clientele.","2012","2025-05-05 17:03:13","2025-05-05 17:03:13","","448","","3","2","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","India; Business And Economics; Trends; Sustainability; Costs; Literature reviews; Poverty; Graduate students; Growth factors; Interest rates; Loan; Mechanical engineering; Microfinance; Microfinance Crisis; Mismanagement; Multiple regression analysis; Social goals","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Our results show that successful FLOSS teams demonstrate a truly global distribution of members, who perform different types of work so as to achieve consistent round-the-clock development, without any apparent ill effects on team productivity and the quality of the resulting outcomes. Cooperation between team members is abundant, especially at more complex work items, and does not seem to be affected by distance; only mentoring relationships appear in some cases to be easier to cultivate between individuals living closer together.

We address two main research questions: 1) What are the main features of FLOSS-based start-ups?; 2) What is their innovation process? We show that FLOSS-based start-ups follow a typical open innovation model that enables them to serve market niches that large incumbents are not structurally able to cover, profiting from the local production, distribution, and use of technological knowledge.

In empirical organizational research, the analysis of two-mode networks is typically accomplished either by (a) decomposition of the dual structure into its two unimodal components defined in terms of indirect relations between entities of the same kind or (b) direct statistical analysis of individual two-mode dyads. Both strategies are useful, but neither is fully satisfactory. In this article, the authors introduce newly developed stochastic actor-based models for two-mode networks that may be adopted to redress the limitations of current analytical strategies. The authors specify and estimate the model in the context of data they have collected on the dual association between software developers and software problems observed during a complete release cycle of an open source software project.

The findings were analysed through the lens of administrative complexity associated with OSS adoption. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS.

For each non-free loop the various inhibitors (to parallelization) are determined and counted. The results show that function calls within for-loops represent the vast majority of inhibitors and thus pose the greatest roadblock to adapt and re-engineer systems to better utilize parallelization. This is somewhat contradictory to the literature, which is focused primarily on the removal of data dependencies within loops. Additionally, the historical data of inhibitor counts for the set of systems is presented over a ten-year period.

Scientific workflows are concerned with, amongst others, supporting the repeatability and provenance of experiments. In context of three sets of research (wildfire research, flood modelling and the linking of disease outbreaks to multi-scale environmental conditions), we describe our efforts to provide geospatial capability for scientific workflow software environments to support researchers in exploring, integrating and visualising earth observation and geographic data in conjunction with other research data. We note that functionalities for data ingest (raster and vector), data transformation (reprojection and simplification), data export and spatial overlay operations commonly are required. We find a relative lack of support for geospatial data, services and these functions within several Free and Open Source Software (FOSS) scientific workflow packages.

This is due to finite-size effects in the networks, and the parameters needed to model finite-size behaviour make a quantitative distinction between the in-directed and out-directed networks.

Early on it was decided to use one software system to run our simulations as well as ultimately handle the event processing for real data. We leveraged many existing HEP external libraries (Geant4, Gaudi Framework, ROOT, CLHEP, CMT) to ease the burden on our developers. This strategy of re-using existing software helped us pull together our system quickly and test during our beam tests and data challenges. Now, after launch, we are in a new phase of the project, where we must move forward to support modern operating systems and compilers to get us through the life of the mission. This means upgrading our external libraries as well, which are not under our direct control. Meanwhile, it is crucial to our production system that we carefully orchestrate all upgrades to insure stability. An additional hurtle is that our number of active developers has dwindled dramatically. Many of those left are Windows developers reliant on the Visual Studio development environment, while our user base and production system depend on our Linux distributions.

For over a decade, the digital communities around the globe have used FOSS packages not only as an inexpensive way to access to information available on Internet, but also to disseminate thoughts, opinions and concerns about various socio-political and economic matters. Proxy servers and FOSS played a vital role in helping citizens in repressed countries to bypass the state imposed Internet content filtering and censorship practices. On the one hand, proxy servers act as redirectors to websites, and on the other hand, many of these servers are the main source for downloading FOSS anti-filtering software packages. These packages can provide secure web surfing via anonymous web access, data encryption. IP address masking, location concealment, browser history and cookie clean-ups but they also provide proxy software updates as well as domain name updates. The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In particular, they are poorly adapted to the slow Internet connections in many developing countries such as Iran. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.

Originally target based, cellular assays provide a way to test compounds (or other biological material such as small interfering RNA) in a more physiologically realistic in vitro environment. High-content screening (HCS) platforms are now available at lower cost, giving the opportunity for universities or research institutes to access those technologies for research purposes.

Recent examples appear to lend support to this, but there exist many detractors of OSS and resistance to the transformation it creates. Thus, it is relevant to take a closer look at the institutionalization of OSS. This paper evaluates the extent of OSS institutionalization in organizations. A practice or innovation is said to be institutionalized when it is taken-for-granted and its use becomes the norm. Drawing on institutional theory, the underlying concept of organizing vision and the rhetorical theory of diffusion of innovations, the authors analyze OSS institutionalization through the observation of the evolution of the public discourse about OSS and, simultaneously, the observation of the rate of adoption or diffusion of OSS in organizations.","2012-12","2025-05-05 17:03:17","2025-05-05 17:03:17","","1308","","12","54","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Institutionalization; Studies; Open source; Software engineering; Open-source software; Organizing vision; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Technological change; Organization theory; Diffusion of innovations; Institutionalisation; Computers–Data Base Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Compared with the prevailing proprietary approaches, open-source software products are developed by co-opting external developers and prospective users. Although a core group of developers might still play a key role in the initial design and development, a notable aspect of the open-source software paradigm is the role of peripheral developers in the enhancement and popularization of the product. Peripheral developers are not formal members of the core development team. They voluntarily contribute their time and creative talent in improving the quality of the product or in popularizing the product through word-of-mouth advocacy. As volunteers, they are not subject to the traditional hierarchical controls, nor are they contractually obligated. Peripheral developers represent a novel and unique aspect of open-source software development, and there is a greater interest in tapping their potential. However, there has been limited evidence about how and when their participation has beneficial impacts. We examine how peripheral developers contribute to product quality and diffusion by utilizing longitudinal data on 147 open-source software products. Hierarchical linear modeling analysis indicates that peripheral developers make significant contributions to product quality and diffusion, especially on projects that are in the more mature stages of product development.","2012-03","2025-05-05 17:03:17","2025-05-05 17:03:17","","144-163","","1","23","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Open source; Product development; Software development; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; Developer; Proprietary; 7500:Product planning & development; Impact fees; Product quality; Product life cycle; Multilevel model; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Adopting open source core components implies a lower degree of control over software development and increased business risk associated with integrating differentiating contributions into the core release stream. Whether and how to adjust the current requirements management practices after the adoption of OSS components to fully benefit from the concept of open innovation has not yet been empirically explored.

These commands are in an intuitive format which provides great flexibility and allows quick and easy adaptation to various measurement needs. For each of these commands, the iC-framework calls a corresponding Java method that addresses the specified instrument to perform the desired task.

This rich diversity of OSS projects, however, presents the greatest hurdle in seamlessly selecting suitable projects for integration. To better understand the scope of this diversity, initially, we propose to manually select uniformly difficult projects of appropriate complexity. Ultimately, based on the experiences and insights acquired through the manual selection, we envision the development of a systematic methodology based on software metrics to ease the project selection process.

Because students are accustomed to gathering information using commercial search engines, they can overlook high-quality library resources. To connect with student researchers when they need library resources, many libraries have built online research guides tied to specific subjects and courses. These guides can address specific assignments where research is required, and course instructors can point students to the guides to assist them in completing their research assignments successfully. In 2006, Oregon State University (OSU) Libraries developed an open source software product called Library a la Carte that librarians can use to construct research guides easily and quickly. The code was made available to other libraries, and a number of institutions have adopted the tool. A successful user community has grown up around Library a la Carte, but development up to this point has been the sole responsibility of OSU Libraries. We are now embarking on building a robust developer community, to contribute code, to build additional features and to take Library a la Carte into the future. As part of our plan to move forward, we are testing a hosted (cloud-based) version of the software.

This paper highlights the valuable semantic information of project descriptions and labels, proposes labeled software topic detection (LSTD), a hybrid approach combining topic models and ranking mechanisms to detect and enrich the topics of software by mining the large amount of textual software profiles, which can be employed to do software categorization and tag recommendation. L-STD makes use of labeled LDA to capture the semantic correlations between labels and descriptions and then construct the label-based topic-word matrix. Based on the generated matrix and the generality of labels, LSTD designs a simple yet efficient algorithm to detect the latent topics of software that expressed as relevant and popular labels.

We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses.

To help participants understand what these tools do and how to use them, we will use process oriented guided inquiry learning (POGIL) activities. In POGIL, learners work in groups of 3 or 4 in guided activities that are structured to help them construct new knowledge. In the two hands-on activities, teams will work through a series of increasingly sophisticated models. In each model, teams will use tools, answer questions, explore options, and report out their findings and lessons learned.

The governing equations underlying MASCARET are the shallow water equations for unsteady flow propagation and the advection-dispersion equation for water quality and contaminant transport. The hydraulic component accounts for floodplains and storage areas, and flow at channel junction can be treated using a 2-D approach. Additionally, flood propagation over dry beds (e. g. dam-break flows) and non-hydrostatic waves can be simulated. The user interface FUDAA-MASCARET manages the input data, allocation of parameters, running of simulations and viewing outputs. MASCARET can be easily compiled as a dynamic library, offering special interfaces to be used with three main steps: Initialization, Run and Finalization of the calculation. With these features, MASCARET can be coupled or integrated to other softwares without requiring significant efforts. Since July 2011, MASCARET is worldwide distributed as an open-source code. In this paper, are presented various applications of this tool covering both flow hydrodynamic and water quality. Model-data comparisons show the performance of the modeling framework, and demonstrate the interest of this open-source software for the scientific community.","2012","2025-05-05 17:03:19","2025-05-05 17:03:19","","1169-1174","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Colegio Ingenieros Civiles Costa Rica; Int Assoc Hydro Environm Engn &\n Res, Comm Fluvial Hydraul ISBN: 978-0-203-07635-4; 978-0-415-62129-8 Place: NA Publisher: NA","","","","NA","","Munoz, R.

Our methods are based on complex network and time-series analysis. We define the notion of a working rhythm as the average time spent on a commit task and we study the correlation between working rhythm and communication frequency. We build communication networks for code developers, and find that the developers with higher social status, represented by the nodes with larger number of outgoing or incoming links, always have faster working rhythms and thus contribute more per unit time to the projects. We also study the dependency between work (committing) and talk (communication) activities, in particular the effect of their interleaving. We introduce multi-activity time-series and quantitative measures based on activity latencies to evaluate this dependency. Comparison of simulated time-series with the real ones suggests that when work and talk activities are in proximity they may accelerate each other in OSS systems. These findings suggest that frequent communication before and after committing activities is essential for effective software development in distributed systems.","2012","2025-05-05 17:03:20","2025-05-05 17:03:20","","78-85","","NA","NA","","","","SOCIALINFORMATICS '12","","","","","","NA","","","","","","","Backup Publisher: Acad Sci & Engn; IEEE Comp Soc ISBN: 978-0-7695-5015-2; 978-1-4799-0234-7 Place: USA Publisher: IEEE Computer Society","","","","social network; open source software; work; committing rhythm; time-series; talk","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The linking mechanisms are modeled as probability functions dependent on the degrees of linking modules. A case study from an open source software project, Drupal, is presented. The evolutionary trends of Drupal product structures are analyzed and discussed. Finally, a model is presented to illustrate the effects of linking mechanisms at the module level on the product structures at the system level.

OSS is an M-class mission to explore the Neptune system almost half a century after the flyby of the Voyager 2 spacecraft. Several discoveries were made by Voyager 2, including the Great Dark Spot (which has now disappeared) and Triton's geysers. Voyager 2 revealed the dynamics of Neptune's atmosphere and found four rings and evidence of ring arcs above Neptune. Benefiting from a greatly improved instrumentation, a mission as OSS would result in a striking advance in the study of the farthest planet of the solar system. Furthermore, OSS would provide a unique opportunity to visit a selected Kuiper Belt object subsequent to the passage of the Neptunian system. OSS would help consolidate the hypothesis of the origin of Triton as a Kuiper Belt object captured by Neptune, and to improve our knowledge on the formation of the solar system. The OSS probe would carry instruments allowing precise tracking of the spacecraft during the cruise. It would facilitate the best possible tests of the laws of gravity in deep space. These objectives are important for fundamental physics, as they test General Relativity, our current theoretical description of gravitation, but also for cosmology, astrophysics and planetary science, as General Relativity is used as a tool in all these domains. In particular, the models of solar system formation uses General Relativity to describe the crucial role of gravity. OSS is proposed as an international cooperation between ESA and NASA, giving the capability for ESA to launch an M-class mission towards the farthest planet of the solar system, and to a Kuiper Belt object. The proposed mission profile would allow to deliver a 500 kg class spacecraft. The design of the probe is mainly constrained by the deep space gravity test in order to minimize the perturbation of the accelerometer measurement.","2012-10","2025-05-05 17:03:21","2025-05-05 17:03:21","","203-242","","2, SI","34","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Industrial users adopting to OSS and the underlying concepts need to consider changing their software development practices and organization in order to benefit from the OSS model. These changes may involve both technical and non-technical aspects. Openness and collaboration with a community are two non-technical concepts that may require such changes, while evaluating OSS products or evaluating different strategies for integrating OSS products are two technical aspects that may require adoption. The objective of this paper is to create an awareness for the adoption of OSS in an industrial context. OSS can be used in different ways. Four categories of using OSS are presented by discussing motivation, implication and experience for each category. The main conclusion from this work is that organizations should have a realistic expectation of both the designated benefits and extension of organizational changes necessary to adopt to OSS.

In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using Cot its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

Unfortunately, because most enterprises view technology as a proprietary differentiating element of their operation, little is known about the extent of OSS adoption in industry and the key drivers behind adoption decisions. In this article we examine factors and behaviors associated with the adoption of OSS and provide empirical findings through data gathered from the US Fortune-1000 companies. The data come from each company's web browsing and serving activities, gathered by sifting through more than 278 million web server log records and analyzing the results of thousands of network probes. We show that the adoption of OSS in large US companies is significant and is increasing over time through a low-churn transition, advancing from applications to platforms. Its adoption is a pragmatic decision influenced by network effects. It is likelier in larger organizations and those with many less productive employees, and is associated with IT and knowledge-intensive work and operating efficiencies. (C) 2011 Elsevier Inc.

Their fate can be predicted using reactive transport models that describe reaction and advective and dispersive movement of these components in their natural environment. Recently a number of software packages have been implemented in the open source software R that allow one to implement reactive transport models. Central to this is the ReacTran R-package, a comprehensive collection of functions for modeling reactive components that may be distributed over multiple phases, whose dynamics are coupled through biological and geochemical reactions, and that are transported in one-, two- or three-dimensional domains with simple geometries. Dedicated solution methods are in R-packages deSolve and rootSolve. The modeling packages facilitate the simulation of reaction and transport of components for spatial scales ranging from micrometers to kilometers and spanning multiple time-scales. As they are influenced in similar ways, the same functions can solve biogeochemical models of the sediment, groundwater, rivers, estuaries, lakes or water columns, experimental setups, or even describe reaction and transport within flat, cylindrical or spherical bodies, such as organisms, aggregates, or the dispersion of individuals on flat surfaces and so on. We illustrate the use of R for reactive transport modeling by three applications spanning several orders of magnitude with respect to spatial and temporal scales. They comprise (1) a model of an experimental flow-through sediment reactor, where fitting so-called breakthrough curves are used to derive sulfate reduction rates in an estuarine sediment, (2) a conservative and reactive tracer addition experiment in a small stream, which implements the concept of river spiraling, and (3) a 2-D and 3-D model that describes oxygen dynamics in the upper layers of the sediment, interspersed with several hotspots of increased reaction intensities. The packages ReacTran, deSolve and rootSolve are implemented in the software R and thus available for all popular platforms (Linux, Windows, Mac). Models implemented using this software are short and easily readable, yet they are efficiently solved. This makes R extremely well suited for rapid model prototyping. (C) 2011 Elsevier Ltd.

We consider code evolution from two aspects: code version changing history in a single project and code reuse history in the whole universe. In the model, files/modules are built as nodes, and relations (version change or reuse) between files/modules are built as connections. Based on the model, we design and implement a code evolution review framework, i.e., Code Evolution Reviewer (CER), which provides a series of data interfaces to review code evolution history, in particular, code version changing in single project and code reuse among projects.

Findings - A business model that embodies open innovation raises dilemmas between open and closed innovation paradigms. However, the authors' case highlights that an ambidextrous approach that combines market orientation with the principles of open innovation increases profitability, shortens time to market through effective market access, and enhances innovation capability. Research limitations/implications - The results have profound implications for industrial marketers, managers, management consultants and business educators. They can use the insights gleaned from this research to guide the development of business models that involve open innovation. The results indicate that firms involved in open innovation need reactive strategic flexibility to cope with the environmental diversity and variability. However, this study analyzes a single case in the field of OSS and one should be cautious when generalizing the findings. Originality/value - This paper improves the understanding of the relationship between flexibility and market orientation. It combines two areas that have previously been discussed separately, i.e. market orientation and open innovation.","2012","2025-05-05 17:03:24","2025-05-05 17:03:24","","1368-1388","","10","46","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Qualitative research; Studies; Open source; Open-source software; Competition; Business model; Intellectual property; Business models; Case study; 5240:Software & systems; Public domain; Freeware; Innovations; Open innovation; 9130:Experimental/theoretical; Competitive advantage; Closed innovation; Flexibility; Market orientation; Scholarly publishing; Business And Economics–Marketing And Purchasing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of Free and Open Source Software (FOSS) projects is one attractive approach for providing students with easy access to a complex, ongoing project of size that is supported by a professional community. Humanitarian FOSS (HFOSS) projects hold the additional appeal to students of developing software that will benefit the human condition. However, student involvement in HFOSS projects can be somewhat unpredictable and less controllable than the development of home-grown projects or projects with an industry partner. Student participation in an HFOSS project means that students are dependent, at least somewhat, on the goals, schedule, and constraints of the HFOSS project itself. Therefore, learning is somewhat reliant on the progress of the HFOSS project. This paper presents results of a multi-year study of student perceptions of learning related to software engineering knowledge and skills while involved in an HFOSS project. The paper includes a background of work in student participation in HFOSS, an outline of the study approach and an explanation of the results. Implications of the results and future directions are also described.","2012","2025-05-05 17:03:24","2025-05-05 17:03:24","","NA","","NA","NA","","","","ASEE Annual Conference & Exposition","","","","","","NA","","","","","","","Backup Publisher: ASEE ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The Artists are in search of open source software tools which can enhance their creative ability and at the same time want to collaborate with others to increase their knowledge on the tool. The creativity is difficult to measure as we have to consider the way the tool is enhancing the creative knowledge of the user using the tool.

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

Alumni and current members of the POSSE (Professors' Open Source Summer Experience, http://communityleadershipteam.org/posse) will attend in mentorship roles. Faculty attendance at the SIGCSE 2010 BoF on Teaching Open Source (TOS) indicates that student involvement in FOSS projects is a teaching and learning approach of interest for many faculty members. The transparency of both artifacts and process make FOSS an attractive real-world experience that enhances peer learning and intrinsic motivation for a diversity of courses, from introductory, interdisciplinary, and non-major classes to software engineering core offerings and senior capstones. However, such student participation involves a significant learning curve and effort on the part of the faculty member, and support structures for faculty are still maturing. 2011-2012 marks the 3rd academic year the TOS community has explored this realm together, and the past year has seen the emergence of more best practices, support resources, and curricular material. Community members are starting to design cross-institutional research on the impact of FOSS participation on students. BoF attendees will be encouraged to ask questions, network, and take advantage of the TOS community as a support structure for their own courses and projects.The audience is expected to consist of instructors who 1) are interested in learning how to get started in involving students in FOSS projects; or 2) have involved students in FOSS projects and are looking for better ways to facilitate student learning within FOSS projects.","2012","2025-05-05 17:03:24","2025-05-05 17:03:24","","676","","NA","NA","","","","SIGCSE '12","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450310987 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","FOSS; open source; communities of practice; teaching open source","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The data, gathered from 607 OSS projects over time (in two snap-shots), were consistent with Dynamic Capability Theory (DCT). In other words, the results showed that in order to achieve higher project performance, OSS projects need to have strong capabilities in terms of proactive and efficient defect-removal as well as proactive and efficient functionality-enhancement.

Although contributors' knowledge building has been repeatedly found to facilitate their project continuance, FLOSS projects are lacking operational advices on how to assist their members' learning. Drawing on previous literature which emphasizes project members' social interactions and their practical experiences to build new knowledge, we propose mentoring as a training method for FLOSS projects. Based on organizational experiences, we propose a measure to evaluate mentoring as an appropriate strategy for FLOSS initiatives to facilitate individuals' learning and to retain their contributors on longitudinal base.","2012","2025-05-05 17:03:25","2025-05-05 17:03:25","","79–84","","NA","NA","","","","SIGMIS-CPR '12","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450311106 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software development; retention; mentoring; free libre open source software; knowledge building; turnover behavior","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then, European universities have been involved in the development of the so-called European Higher Education Area (EHEA), including the adoption of a system of easily readable and comparable degrees, the European co-operation in quality assurance, and the promotion of mobility and European dimension in higher education. In this framework, the use of Free Open Source Software (FOSS) could provide several advantages, related to both the freedom given to users and the strengths of its peer-to-peer development model. In fact, some of the most outstanding characteristics of the FOSS (free, democratic, sustainable and technologically competitive educational model, cooperative and competitive relationships,.) result to be coincident with the main aims of the European Higher Education Area. In this paper we describe the role that this Free Open Source Software could play in the University context, also providing some statistical evidence about FOSS penetration and its recent evolution. Furthermore, since the implementation of the new university degrees can be considered as a “break point”, we briefly describe our FOSS experiences at the University of Oviedo, involving Statistics and Econometrics. Finally, we summarize the conclusions and describe the main challenges that FOSS must face during the coming years.","2012","2025-05-05 17:03:26","2025-05-05 17:03:26","","4841-4846","","NA","NA","","","","EDULEARN Proceedings","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-84-695-3491-5 Place: LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN Publisher: IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","","","","FOSS; Econometrics; Bologna Process; EHEA; Gretl; University","","Chova, L.

Developed countries have significantly benefited from these innovations whereas developing economies are still battling with the many challenges that have hindered e-learning success. The advent of Web 2.0 and Free Open Source Software (FOSS) would have been seen as the breakthrough for the developing economies to embrace e-learning. However, many factors still impede the utilization of these technologies for e-learning. The major objective of this paper is to discuss the factors that hinder institutions from utilizing Web 2.0 and FOSS for e-learning. Content analysis was used to evaluate the factors that had been identified in literature and to tally them according to their frequency. 36 factors were deduced and analyzed using structural equation modeling (SEM) method. Results indicated that technological factors predominantly impact on the utilization of Web 2.0 and FOSS for e-learning.

The early identification of developers who are likely to remain is thus an eminent challenge for the management of FLOSS initiatives. Previous research has shown that individuals' subjective assessment is often inaccurate emphasizing the need to objectively evaluate retention behavior. Consistent with the concepts Person-Job (P-J) and Person-Team (P-T) fit from the traditional recruitment literature, we derive objective measures to predict developer retention in FLOSS projects. In an analysis of the contribution behavior of former Google Summer of Code (GSoC) students we reveal that the level of development experience and conversational knowledge is strongly associated with retention. Surprisingly, our analysis reveals that students with abilities that are underrepresented in the project and students with a higher academic education do not remain considerably longer.","2012","2025-05-05 17:03:27","2025-05-05 17:03:27","","3446–3455","","NA","NA","","","","HICSS '12","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9780769545257 Place: USA Publisher: IEEE Computer Society","","","","Open source; Open Source Software; Open source software development; Developer Retention; IS personnel; OSS/FLOSS; Recruiting; Team staffing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, while there is no shortage on research on individuals' motivation for contributing to open source, few have investigated the commercial companies' motivations for doing the same. A case study was conducted at three different companies from the IT service industry, to investigate three possible drivers: sale of complimentary services, innovation and opensourcing (outsourcing). We offer three conclusions. First, we identified three main drivers for contributing to open source, which are (a) selling complimentary services, (b) building greater innovative capability and (c) cost reduction through opensourcing to an external community. Second, while previous research has documented that the most important driver is selling complimentary services, we found that this picture is too simple. Our evidence points to a broader set of motivations, in the sense that all our cases exhibit combinations of the three drivers. Finally, our findings suggest that there might be a shift in how commercial companies view open source software.

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS.

This study considers the implications of pricing thresholds on government procurement processes in light of the advent and increasing use of free enterprise software. Researchers conducted a randomized Web-based survey of 138 government procurement officials (IT managers). The results indicate that free software may provide procurement officials with an opportunity to bypass institutionalized procurement best practices. The fieldwork indicates that IT purchases made through a full procurement process may enjoy a higher level of satisfaction than purchases of paid and free software acquired with limited or no procurement process review.","2012","2025-05-05 17:03:27","2025-05-05 17:03:27","","197–226,230","","2","41","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Law; Decision making; Information technology; Studies; Software; Free software; Government; Costs; Business models; 9130:Experiment/theoretical treatment; Freeware; 9190:United States; 9550:Public sector; 5120:Purchasing; 5220:Information technology management; Best practice; Budgets; Government procurement; Government purchasing; Neutrality; Procurement; Public interest; Purchase options; User satisfaction; United States–US","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We contend that increased network centrality and closure among current adopters contribute positively to adoption, whereas the same among potential adopters has exactly the opposite impact. Accordingly, we propose a dynamic view where the fraction of current adopters in the network positively moderates the impact of network centrality and closure.

The challenge facing most organizations is how to evaluate OSS adoption benefits. OSS adoption is a complex phenomenon which requires an interdisciplinary approach to understand the socio-technical, political, economic and legal benefits. The complexity of the OSS phenomenon has resulted in fiercely contested, contradictory rhetorical discussions among divided parties with no conclusive general agreement. The one size fits all approach is fundamentally flawed for evaluating OSS benefits in organizations as they are both subjective and contextual. In this paper we propose a framework to balance the needs of hard (objective) benefits and soft (subjective) benefits of OSS adoption in public sector organizations. This paper proposes a framework to evaluate benefits of OSS adoption in public-sector organizations, since one-size-fits-all approaches have shortcomings to complex phenomena.","2013","2025-05-05 17:03:28","2025-05-05 17:03:28","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-0-615-55907-0 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Part of the problem is because ISP providers lack the model to help them facilitate the building of sustainable communities. In this paper, we present a model for creating and sustaining communities on the ISP being developed by the National Institute of Information and Communications Technology (NICT) of Japan. Inspired by the way Open Source software communities operate, we describe the model concept, its settings, and the tools ISP communities may need to support their contribution towards the development of products and services.

Due to its rapid development, OSS manuals become easily obsolete. Moreover, the installation or the usage varies depending on the operating system. To solve the documentation problems, Murakami et al. proposed a method of automatically generating a web manual for installing an OSS by editing the log information recorded during the installation process. Unfortunately, the web manual generated by this system was not suitable for wide use in learning management systems. Therefore, this paper extends the system by Murakami et al. to one with the ability to deliver an automatically generated Web manual on an e-learning management system, modify the content of the manual, and skip unnecessary information in the learning process.

In this paper Phoebus user-friendly software for an automatic use of the extended parabolic bay shape equation is presented. The software enables both technical experts and non-professionals to conduct expeditious analysis in order to evaluate the evolution and equilibrium conditions of embayed littoral beaches lying between natural headlands or man-made structures, as well as to artificially recreate stable embayed beaches by building new artificial structures on open beaches. The software can be also used for coastal planning, to anticipate beach modifications in response to new building or to changes in pre-existing structures. Highlights 1.

Collectively, these data can be analyzed for such purposes as disease diagnosis or phenotype classification. One family of algorithms that has proven useful for disease classification is based on relative expression analysis and includes the Top-Scoring Pair (TSP), k-Top-Scoring Pairs (k-TSP), Top-Scoring Triplet (TST) and Differential Rank Conservation (DIRAC) algorithms. These relative expression analysis algorithms hold significant advantages for identifying interpretable molecular signatures for disease classification, and have been implemented previously on a variety of computational platforms with varying degrees of usability. To increase the user-base and maximize the utility of these methods, we developed the program AUREA (Adaptive Unified Relative Expression Analyzer)-a cross-platform tool that has a consistent application programming interface (API), an easy-to-use graphical user interface (GUI), fast running times and automated parameter discovery. Results: Herein, we describe AUREA, an efficient, cohesive, and user-friendly open-source software system that comprises a suite of methods for relative expression analysis. AUREA incorporates existing methods, while extending their capabilities and bringing uniformity to their interfaces. We demonstrate that combining these algorithms and adaptively tuning parameters on the training sets makes these algorithms more consistent in their performance and demonstrate the effectiveness of our adaptive parameter tuner by comparing accuracy across diverse datasets. Conclusions: We have integrated several relative expression analysis algorithms and provided a unified interface for their implementation while making data acquisition, parameter fixing, data merging, and results analysis `point- and -click' simple. The unified interface and the adaptive parameter tuning of AUREA provide an effective framework in which to investigate the massive amounts of publically available data by both `in silico' and `bench' scientists.

An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess “proof” of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and activities match those in their paid employment. Following a cohort of OSS programmers over a six-year period, we empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, our findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18% increase in wages. Moreover, we find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management. These findings suggest that rank within an OSS meritocracy is a credible and precise signal of participants' productive capacity and that participants' roles and activities in an OSS community have additional financial value when aligned with their paid employment.","2013-09","2025-05-05 17:03:30","2025-05-05 17:03:30","","520-538","","3","24","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS","","","","open source software; signaling theory; job matching theory; software industry; labor\n economics","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study analyzes the usefulness of the textual content of the defect reports as an early indicator of their resolution time. Text Mining techniques are used to categorize defect reports of five OSS projects. Significant variation in the defect resolution time amongst the resulting categories, for each of the sample projects, indicates that a text based classification of defect reports can be useful in early assessment of resolution time before source code level analysis. Such technique can assist in allocation of sufficient maintenance resources to targeted defects and also enable project teams to manage customer expectations regarding defect resolution times.","2013-02","2025-05-05 17:03:30","2025-05-05 17:03:30","","117-138","","1","18","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose an empirical method to validate a software development model for FLOSS, the Adapted Staged Model for FLOSS. We mined some selected metrics from Apache Ivy and study their evolution using S-shaped curves. Our results indicate that S-shaped curves can model software evolution well for Ivy. Moreover, we demonstrated that our method can be used to identify successfully different stages of its development, validating part of the Adapted Staged Model for FLOSS.","2013","2025-05-05 17:03:30","2025-05-05 17:03:30","","468–471","","NA","NA","","","","ICSM '13","","","","","","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Software Improvement\n Grp; Lab Qual Software ISBN: 9780769549811 Place: USA Publisher: IEEE Computer Society","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Business process management is intended to implement efficient and customer orientated processes whereby the simulation of business processes can be used to evaluate the quality of processes and to identify areas of improvements. Since real business processes usually contain decision processes which can be solved by optimization systems, it makes sense to,combine the simulation and the optimization of business processes. (Marz et.al. 2010, p 3ff.) As an example of a reasonable combined simulation and optimization of business processes, the navigation in a road network is discussed in this paper. Consider vehicles seeking the fastest route from a starting node to a target node using a navigation system. The amount of time spent driving on an arc is influenced by the distance and the amount of the vehicles on this arc and is continuously changing. The structure of the road network and the traffic within the network is described in a simulation model while the fastest path decisions of each vehicle are made by using an optimization system. There is obviously a relationship between the individual decisions made for each of the vehicles and the state of the entire network. The aim of this paper is to describe how a combined simulation and optimization of business processes can be created through using EPC-Simulator (Muller 2012) as a simulation system and CMPL (Steglich and Schleiff 2010) as an optimization system where the network traffic simulation is used exemplarily.","2013","2025-05-05 17:03:30","2025-05-05 17:03:30","","808+","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: European Council Modelling & Simulat; Aalesund Univ Coll; Res Council\n Norway; More & Romsdal Cty Municipal; Rolls Royce Marine; Offshore\n Simulator Ctr AS; Farstad Shipp; Sparebanken More; Tekna; Norwegian\n Maritime Competence Ctr ISBN: 978-0-9564944-6-7 Place: NA Publisher: NA","","","","NA","","Rekdalsbakken, W.; Bye, R.

We first analyze the general structure of the social networks, e.g., graph distances and the degree distribution of the social networks. Our analysis confirms that the social networks of OSS communities follow power-law degree distributions and exhibit small-world characteristics. However, the degree mixing pattern shows that high degree nodes tend to connect more with low degree nodes, suggesting collaborations between experts and newbie developers. Second, we study the correlation between graph degrees and the productivity of the contributors in terms of the amount of contribution and commitment to OSS projects.

This article aims at developing a research model for investigating the antecedents of OSS adoption decisions in HCOs. Methods: Based on a conceptual framework derived from a synthesis of the literature on IT adoption in organizations, we conducted 18 semi-structured interviews with IT experts from all levels of the Province of Quebec's health and social services sector in Canada. We also interviewed 10 IT suppliers in the province. A qualitative data analysis of the interviews was performed to identify major antecedents of OSS adoption decisions in HCOs. Results: Eight factors associated with three distinct theoretical perspectives influence OSS adoption. More specifically, they are associated with the classical diffusion of innovations theory, the theory of resources, as well as institutional theory and its spin-off, the organizing vision theory. The factors fall under three categories: the characteristics of OSS as an innovation, the characteristics of the HCO with respect to its ability to absorb OSS, and the characteristics of the external environment with respect to institutional pressures and public discourse surrounding OSS. We shed light on two novel factors that closely interact with each other: (1) interest of the health care community in the public discourse surrounding OSS, and (2) clarity, consistency and richness of this discourse, whether found in magazines or other media. Conclusions: OSS still raises many questions and presents several challenges for HCOs. It is crucial that the different factors that explain an HCO's decision on OSS adoption be considered simultaneously. Doing so allows a better understanding of HCOs' rationale when deciding to adopt, or not to adopt, OSS. (C) 2013 Elsevier Ireland Ltd.

Data model can be accessed by desktop application as well as from Internet. This second option is becoming today the most requested. But in order to share 3D data model through Internet it is necessary to configure a suitable system. A 3D model can be shared on Internet in different ways. It is possible to incorporate a model inside an executable or 3D PDF file or build something like a multimedia application (i.e. flash based). However a better option is to put a model inside a geospatial database and build suitable web services to access it using Internet browsers. This second option can be performed using different solutions for web servers, development platforms and programming languages. Fundamental for this option is the construction of the model that should be structured, according a conceptual model to be replicable and interoperable. Hence, the model should be stored in a geospatial database in order to be accessed by an application running under a web server, so allowing access to the model. All this is the object of the research-Management and use of distributed 3D data by open source WebGIS software-that is part of the Italian PRIN 2007 research project: Interoperability and cooperative management of geographic, dynamic, multi-dimensional and distributed data with Free and Open Source GIS (Principal investigator Paolo Zatelli), aimed to build urban and suburban 3D models with CAD software or solid modellers, share them with a 3D Web Feature Service Open Geospatial Consortium web feature service like, and them using Internet browsers all done using only free and open source software. The research work, here illustrated, which was funded by previous research project, deals with the construction of a suitable model and the storage of the model inside a geospatial database. The work is based on the use of free and open source software; Blender and PostgreSQL with PostGIS have been used, respectively, to draw objects of the model and save their data with the help of some Python scripts; the server side part of the system has been realized using Tomcat with servlets and applets all written in Java. Buildings have been modelled according to GIANT3D model (Geographical Interoperable Advanced Numerical Topological 3-Dimensional Model) previously developed in the research “PRIN 2004”, regarding “Evolved structure of numerical cartography for GIS and WebGIS”. Python scripts, activated by Blender, allow saving data into a spatial database implemented through PostgreSQL and PostGIS that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, is so transferred in PostGIS. This information can be retrieved by Blender using other Python scripts, so Blender fully interacts with 3D data allocated in PostGIS. These data can be also accessed by many other clients, both directly using a database client and using other protocols (like HTTP on Internet). The second part of the research deals with the creation of a 3D Web Feature Service and an applet for internet browsers, in order to allow clients to visualize, explore and inquiry 3D model, retrieving data from database.","2013-06","2025-05-05 17:03:31","2025-05-05 17:03:31","","119-132","","2","5","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 7 0 0; 0 0 0 bug reports obtained from the BUGZILLA installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3% with an associated recall of 38.9%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.","2013","2025-05-05 17:03:31","2025-05-05 17:03:31","","1032-1041","","NA","NA","","","","ICSE '13","","","","","","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM Special Interest Grp Software Engn; IEEE Comp\n Soc; Tech Council Software Engn ISBN: 978-1-4673-3076-3 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","Notkin, D.; Cheng, B.

Free and open available tools like GridLAB-D, PSAT, OpenModelica and 4DIAC are well known and widely used because of their excellent domain specific expertise. With co-simulation approaches the individual strengths of each tool can be exploited to model and simulate the various aspects of complex smart grids. The achieved level of detail and realism potentially surpasses the results that the individual analyses would gain. This paper demonstrates a local smart charging control strategy implemented with the IEC 61499-based standard for distributed control systems.

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lockin, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.","2013-01","2025-05-05 17:03:32","2025-05-05 17:03:32","","7-12","","1","3","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES","","","","Open source software; Business And Economics; Open source; open source software; Software; innovation; Open-source software; sustainability; Sustainability; Social; Software development; Public domain; Code; code forking; Freeware; planned obsolescence","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This kind of streaming technology is mainly used with HTTP 1.0 and 1.1 respectively, which both have some drawbacks. Therefore, the IETF has started the development of HTTP 2.0, which is based on Google's SPDY proposal and already supported by several major companies, e. g., Facebook, Twitter, Akamai, Mozilla and obviously Google. Furthermore, Content Centric Networking (CCN) is another novel approach for future networks that is considered as an revolutionary approach compared to HTTP 2.0. The CCN communication paradigm is completely different and does not rely on direct connections between hosts, it rather focuses on the content. This paper demonstrates DASH with HTTP 2.0/SPDY and CCN using our universal libdash library. Moreover, different mechanisms of DASH will be shown that can be used to provide on-demand and live content in an efficient and comfortable way.","2013","2025-05-05 17:03:33","2025-05-05 17:03:33","","NA","","NA","NA","","","","IEEE International Conference on Multimedia and Expo Workshops","","","","","","NA","","","","","","","Backup Publisher: IEEE ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper examines the development of a web GIS application as part of an emission inventory system that produces maps and files with spatial allocated emissions in a grid format. The study is not confined in the maps produced but also presents the features and capabilities of a web application that can be used by every user even without any prior knowledge of the GIS field. The development of the application was based on open source software tools such as MapServer for the GIS functions, PostgreSQL and PostGIS for the data management and HTML, PHP and JavaScript as programming languages. In addition, background processes are used in an innovative manner to handle the time consuming and computational costly procedures of the application. Furthermore, a web map service was created to provide maps to other clients such as the Google Maps API v3 that is used as part of the user interface. The output of the application includes maps in vector and raster format, maps with temporal resolution on daily and hourly basis, grid files that can be used by air quality management systems and grid files consistent with the European Monitoring and Evaluation Programme Grid. Although the system was developed and validated for the Republic of Cyprus covering a remarkable wide range of pollutant and emissions sources, it can be easily customized for use in other countries or smaller areas, as long as geospatial and activity data are available.

A further, cross-cutting characterization of developers could be achieved by associating developers with “time slots”, and different patterns of activity and effort could be associated to such slots. Such analysis, if replicated, could be used not only to compare different FLOSS communities, and to evaluate their stability and maturity, but also to determine within projects, how the effort is distributed in a given period, and to estimate future needs with respect to key points in the software life-cycle (e.g., major releases). This study analyses the activity patterns within the Linux kernel project, at first focusing on the overall distribution of effort and activity within weeks and days; then, dividing each day into three 8-hour time slots, and focusing on effort and activity around major releases. Such analyses have the objective of evaluating effort, productivity and types of activity globally and around major releases. They enable a comparison of these releases and patterns of effort and activities with traditional software products and processes, and in turn, the identification of company-driven projects (i.e., working mainly during office hours) among FLOSS endeavors. The results of this research show that, overall, the effort within the Linux kernel community is constant (albeit at different levels) throughout the week, signalling the need of updated estimation models, different from those used in traditional 9am-5pm, Monday to Friday commercial companies. It also becomes evident that the activity before a release is vastly different from after a release, and that the changes show an increase in code complexity in specific time slots (notably in the late night hours), which will later require additional maintenance efforts.","2013-02","2025-05-05 17:03:33","2025-05-05 17:03:33","","60-88","","1","18","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are many methods which are being followed to make the students understand concepts. One such method is the use of CAD tools When computers came into class rooms, the need for CAD tools also arose [1]. They help the students to visualize many basic concepts which, they otherwise cannot see in the physical world. In this 21st century, dominated by social networking, the tools required to educate them have also come to be available in free of cost. Such tools are called open source software or FOSS tools. We have proposed a teaching methodology that involves the usage of open source software tools along with traditional teaching which enable the communication engineering students to understand complex concepts pertaining to the subject of Antenna and wave propagation. We carried out an experiment with forty students from fifth semester Electronics and Communication Engineering department. The students used a FOSS tool and gave a test based on designing of various antennas with desired radiation patterns by selecting different parameters before and after using the tool. The scores of the two tests show that there was an increase in the marks obtained by students in the test after using the tool. Thus the use of FOSS tool helped students perform better in the test. This may be because the tool has visualizations which help student understand the abstract concepts such as antenna radiation pattern and wave propagation.","2013","2025-05-05 17:03:33","2025-05-05 17:03:33","","101-104","","NA","NA","","","","IEEE International Conference on Technology for Education","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 978-0-7695-5141-8 Place: NA Publisher: NA","","","","NA","","Kinshuk; Iyer, S.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Variability in these systems not only occurs in functionality, but also in quality attributes (e. g., security, reliability, dependability). Furthermore, variability in functionality and variability in quality attributes affect each other. Recently, open source communities have adopted microblogging to document and share software engineering knowledge. Microblogging dissolves boundaries between developers and other stakeholders (e.g., end users). This facilitates the involvement of many different non-technical stakeholders in the software development process. In this paper, we investigate the feasibility and suitability of utilizing microblogs to identify and analyze dependability information about open source software systems. We use the example of the currently most popular microblogging infrastructure (Twitter) and a widely used open source content management system (Drupal). Our results indicate that even though open source communities frequently share information on Twitter, challenges exist for extracting and analyzing dependability information. Furthermore, a better understanding is needed to describe the relation between issues reported by user communities in microblogs, and issues and actions documented by developer communities in change logs and release information.","2013","2025-05-05 17:03:33","2025-05-05 17:03:33","","321-325","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: IEEE ISBN: 978-1-4799-2552-0 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We derive a model from extant research and refine it through the study of three inter-organisational networks. The findings reveal how a firm's ability to access a value network of complementors is crucial for effective value creation and capture. Two types of networks are evident: a high-density network of familiar partners and a low-density network of multiple, often unfamiliar, partners. Leveraging these networks depends on the level of commitment, volume of knowledge exchange and the alignment of objectives among participant firms.

Overland flooding, the most common type of flooding event usually occurs when rivers or streams overflow their banks as a result of heavy rainfalls or fast snowmelt. In European Union, flood defence management is an essential part of the integrated water management and the European Commission Directive 2007/60, regarding the estimation and management of the flood risks, states that all the member countries have to achieve flood risks maps till the end of 2013. Flood hazard maps must be created to help the communities in finding out which are the different flood risk areas and to provide public awareness and useful information to local authorities and decisions makers in case of possible flood events. Flood risk areas should be also identified and delimited for future land use and development. The development of risk maps assumes the existence and access to extensive databases, detailed maps and GIS data depots for most of the necessary information, as well as expensive software (i.e. ArcGIS, MIKE) and skilled experts. Unfortunately, these criteria are not always met. This paper presents an alternative method to prepare preliminary floodplain maps, based on the use of Autodesk products and Open Source software. The purpose of the method is to introduce basic satellite image display and processing techniques using open source software and freely available satellite data to allow floodplain maps development without using expensive software and unaffordable data. The method consists in DTM (Digital Terrain Model) generation, rivers and watershed delineation and hydraulic modelling in order to generate floodplain maps.","2013","2025-05-05 17:03:34","2025-05-05 17:03:34","","481+","","NA","NA","","","","International Multidisciplinary Scientific GeoConference-SGEM","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-619-7105-04-9 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The spread of diseases like influenza depends on the mixing patterns within the population, and these mixing patterns depend in part on local factors including the spatial distribution and age structure of the population, the distribution of size and composition of households, employment status and commuting patterns of adults, and the size and age structure of schools. Finally, public health planners must take into account the health behavior patterns of the population, patterns that often vary according to socioeconomic factors such as race, household income, and education levels. Results: FRED (a Framework for Reconstructing Epidemic Dynamics) is a freely available open-source agent-based modeling system based closely on models used in previously published studies of pandemic influenza. This version of FRED uses open-access census-based synthetic populations that capture the demographic and geographic heterogeneities of the population, including realistic household, school, and workplace social networks. FRED epidemic models are currently available for every state and county in the United States, and for selected international locations. Conclusions: State and county public health planners can use FRED to explore the effects of possible influenza epidemics in specific geographic regions of interest and to help evaluate the effect of interventions such as vaccination programs and school closure policies. FRED is available under a free open source license in order to contribute to the development of better modeling tools and to encourage open discussion of modeling tools being used to evaluate public health policies. We also welcome participation by other researchers in the further development of FRED.","2013-10-08","2025-05-05 17:03:34","2025-05-05 17:03:34","","NA","","NA","13","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite good development practices, thorough testing, and proper maintenance policies, a non-negligible number of bugs remain in the released software. Understanding the type of residual bugs is fundamental for adopting proper countermeasures in current and future software releases. Depending on the fault triggering conditions that lead to a failure, developers can introduce fault-tolerance mechanisms and plan verification and validation strategies. In this paper, we analyze bugs in four large open-source software systems during their lifecycle, based on the concept of fault triggers. We first investigate how the type of system affects the bug type proportions, and their evolution over years. Then, an analysis of bug subtypes is performed, so as to better understand their nature, followed by a comparison with respect to attributes such as their average time to fix and severity.","2013","2025-05-05 17:03:34","2025-05-05 17:03:34","","178-187","","NA","NA","","","","Proceedings International Symposium on Software Reliability Engineering","","","","","","NA","","","","","","","Backup Publisher: IEEE ISBN: 978-1-4799-2366-3 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.","2013-11-01","2025-05-05 17:03:34","2025-05-05 17:03:34","","597-625","","4","42","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 2-4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND Publisher: ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD","","","","free software; reputational capital; copyleft; immaterial labour; new spirit of capitalism; \n open source","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We approach these adoption challenges as a problem of gaining support for organizational innovation. Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are-on average-more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect.

The culture and norms of FLOSS appear to be formulated by what is privileged/marginalized by men in the context of FLOSS, and such men's valuing is likely to threaten women FLOSS participants' face. Our findings are 1) in the FLOSS context, there are gender-based differences in determining what threatens face on the basis of gendered expectations of what is polite, and 2) women-dominated FLOSS participants are “practically” polite in software development practices. These findings were explored through an in-depth analysis of interaction episodes on the email list, archival public interview data of women FLOSS developers, FLOSS development environment, and instructive materials shared in public.

Larger teams tend to producemore favorable project performance when the project being developed has a high level of structural interdependency while projects with a low level of structural interdependency require smaller teams in order to achieve better project performance. Meanwhile, centralized teams tend to have a positive impact on project performance when the OSS project has a high level of structural interdependency.

We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively.

In this paper we study the role of services in open source software development and explore the choice between open source and proprietary software. Specifically, our economic model jointly analyzes the investment and pricing decisions of the originators of software and of subsequent open-source contributors. We find that if a contributor is efficient in software development, the originator should adopt an open-source strategy, allowing the contributor to offer higher total quality and capture the higher end of the market while the originator focuses on providing software services to lower end consumers. Conversely, if the contributor is not efficient in development, the originator should adopt a proprietary software development strategy, gaining revenue from software sales and squeezing the contributor out of the services market. In certain cases an increase in originator development efficiency can result in increased contributor profits. Finally, we find that, somewhat counterintuitively, an increase in contributor development efficiency can reduce overall social welfare.","2013-12","2025-05-05 17:03:37","2025-05-05 17:03:37","","1068-1086","","4","24","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Information systems; Studies; Open source; Software; Open-source software; Product development; License; Competition; Software quality; 5240:Software & systems; 9130:Experiment/theoretical treatment; Impact analysis; Licensing; 1130:Economic theory; Economic models; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

The skeletal muscle chemoelectromechanical model is based on a bottom-up approach modeling the entire excitation-contraction pathway by strongly coupling a detailed biophysical model of a half-sarcomere to the propagation of action potentials along skeletal muscle fibers and linking cellular parameters to a transversely isotropic continuum-mechanical constitutive equation describing the overall mechanical behavior of skeletal muscle tissue. Since the multiscale model exhibits separable time scales, a special emphasis is placed on employing computationally efficient staggered solution schemes. Further, the implementation builds on the open-source software library OpenCMISS and uses state-of-the-art parallelization techniques taking advantage of the unique anatomical fiber architecture of skeletal muscles. OpenCMISS utilizes standardized data structures for geometrical aspects (FieldML) and cellular models (CellML). Both standards are designed to allow for a maximum flexibility, reproducibility, and extensibility. The results demonstrate the model's capability of simulating different aspects of nonisometric muscle contraction and efficiently simulating the chemoelectromechanical behavior in complex skeletal muscles such as the tibialis anterior muscle.","2013","2025-05-05 17:03:38","2025-05-05 17:03:38","","NA","","NA","2013","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages.

We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially influence how a new OSS project chooses among such licenses and how the experiences of the project manager of a new OSS project with particular licenses affects its susceptibility to this social influence. We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Our results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its inter-project social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. We also find that managers of new projects who have been members of more successful prior OSS projects and who have greater depth and diversity, of experience in the OSS community are less susceptible to social influence. Finally, we find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license.

Traditional approach to teaching these processes has the disadvantage of a presentation largely of information not directly corresponding with the real phenomenon (understanding sectional warping phases). For this purpose requires the use of multimedia presentations for the connection between information and the phenomenon described These presentations can be made classical, in the course room, but for better depth can use different e-learning systems. The purpose of this paper is to present several open source solutions that can be applied to study the processes of weaving (eXe Learning, Hot Potatoes, and so on)., This software can be used to create interactive courses that the student may approach based on complexity.

Information is structured so that they comply with the requirements of a weaving technology. The teacher can generate in the same course, a number of subsections which the student can learn in the same order or according to his need Can be attached multimedia materials, its own teacher, and reference may be made to the existing materials on the Internet. The software has the possibility to generate tests with the answers that have the disadvantage that the order is the same, but you can use special software to test for generating (like Hot Potatoes). The course can be saved in different formats so it can be uploaded on a platform of e-learning or may be used independently, without access to the Internet (with saving multimedia materials to another medium), etc.","2013","2025-05-05 17:03:38","2025-05-05 17:03:38","","434-439","","NA","NA","","","","eLearning and Software for Education","","","","","","NA","","","","","","","Backup Publisher: Games & Learn Alliance; intuitext Grup SOFTWIN; ASCENDIA DESIGN; SAP;\n INSOFT Dev & Consult; MAGUAY; Adv Technol Syst; PLAGIAT ISBN: NA Place: NA Publisher: NA","","","","NA","","Roceanu, I.; Logofatu, B.; Stanescu, M.; Blaga, M.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we propose and validate two antecedents of organizational investment in internal human capital in the context of OSS adoption. They are (1) firm-specificity of OSS human capital, which denotes the extent to which the internal OSS human capital is strongly tied to the organization and cannot be equally well applied in other organizations, and (2) learning-related scale, which reflects the extent to which the organizational cost of learning OSS can be spread by applying the knowledge gained to other projects and business functions within the organization. Survey data collected from 114 senior Information Technology (IT) managers and professionals indicates that these two factors are positively associated with the investment in cultivating internal OSS human capital.","2013","2025-05-05 17:03:38","2025-05-05 17:03:38","","42-52","","1","54","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Studies; Open-source software; Knowledge; Competition; Technology adoption; Organization; Organizational behavior; Enterprise resource planning; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 2500:Organizational behavior; Human capital; Human Capital; Innovations; Competitive advantage; Employees; Skills; Integrated library systems-ILS","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Similar challenges may be present in other self-organised, virtual team environments. In this paper we present preliminary observations and results of in-progress research that studies the process of onboarding into virtual OSS teams.

Influenced by the “creative elements” of OSS, individuals in organizations often forget that the end result of software implementation is to improve productivity, thereby creating a negative impression on OSS implementation strategy as a whole. In this study, we argue that fit between the individual's task, values and work demands can influence or hinder the sustained use of OSS. We explore how task-technology fit and two dimensions of person-organization fit (value-based fit and demand-ability fit) interact with each other to influence productivity performance. Using survey data, we find that congruence between the organization's OSS values and the individual user's OSS values (value-based fit), decreases productivity performance, whereas, fit between an individual's OSS skills and the organizational task demands (demandability fit), increases productivity performance.

However, in a research context it would often be useful to be able to modify this code and/or to have full control over all these parameters from researcher-written software. In the case of the STAR Cryoelectronics PCI/PFL family of SQUID control electronics, the supplied software contains modules for automatic tuning and noise characterization, but does not provide an interface for user code. On the other hand, the Magnicon SQUIDViewer software package includes a public application programming interface, but lacks auto-tuning and noise characterization features. To overcome these and other limitations, we are developing an “open-source” framework for controlling SQUID electronics, which should provide maximal interoperability with user software, a unified user interface for electronics from different manufacturers, and a flexible platform for the rapid development of customized SQUID auto-tuning and other advanced features.

This results in multiple versions or evolving nature of a software. Identification of parts of a software that are more prone to changes than others is one of the important activities. Identifying change prone classes will help developers to take focused and timely preventive actions on the classes of the software with similar characteristics in the future releases. In this paper, we have studied the relationship between various object oriented (OO) metrics and change proneness. We collected a set of OO metrics and change data of each class that appeared in two versions of an open source dataset, `Java TreeView', i.e., version 1.1.6 and version 1.0.3. Besides this, we have also predicted various models that can be used to identify change prone classes, using machine learning and statistical techniques and then compared their performance. The results are analyzed using Area Under the Curve (AUC) obtained from Receiver Operating Characteristics (ROC) analysis. The results show that the models predicted using both machine learning and statistical methods demonstrate good performance in terms of predicting change prone classes. Based on the results, it is reasonable to claim that quality models have a significant relevance with OO metrics and hence can be used by researchers for early prediction of change prone classes.","2013-12","2025-05-05 17:03:40","2025-05-05 17:03:40","","NA","","6, SI","20","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, identifying a project appropriate for student involvement can be a difficult task. There are a huge number of possible FOSS projects with a wide range of sizes, complexity, and domains. The presenters of this workshop have developed an approach to FOSS project identification [1] which is based on several years of experience with student participation in FOSS projects.

It presents an analysis of the software ecosystem itself and the different characteristics it has. Based upon the conducted analysis with the available dataset, the research concludes that the free open source software ecosystem of Python contains three ecosystem roles that define its ecosystem. Next to that, it has grown exponentially from 31 active developers in 2005 to 5,212 December 2012. These results can help set up a strategy for the future of the Python ecosystem. At this point in time, it is necessary to make arrangements for the ongoing growth of the Python ecosystem.

Open source software solutions offer great opportunities for cost reduction and quality improvement, especially for small and medium enterprises that typically have to address major difficulties due to the limited resources available for selecting and adopting a new software system. Objective: This paper aims to provide support for selecting the open source software that is most suitable to the specific needs of an enterprise from among the options offering equivalent or overlapping functionality. Method: This paper proposes a framework for evaluating the quality and functionality of open source software systems. The name of the framework is EFFORT (Evaluation Framework for Free/Open souRce projecTs). It supports the evaluation of product quality, community trustworthiness and product attractiveness. The framework needs to be customised to the analysis of software systems for a specific context. Results: The paper presents the customisation of EFFORT for evaluating Enterprise Resource Planning (ERP) open source software systems. The customised framework was applied to the evaluation and comparison of five ERP open source software systems. The results obtained permitted both the refinement of the measurement framework and the identification of the ERP open source software system that achieved the highest score for each chosen characteristic. Conclusion: EFFORT is a useful tool for evaluating and selecting an open source software system. It may significantly reduce the amount of negotiation conducted among an enterprise's members and reduce the time and cost required for gathering and interpreting data. The EFFORT framework also considers the users' opinions by introducing relevance markers associated with the metrics and questions in the data aggregation process. (C) 2013 Elsevier B.V.

This paper seeks to broaden the research on virtual communities by applying the theory of competency rallying (TCR) in a longitudinal manner to examine the impact of task identification, task assignment, task execution and task management on user interest in open source software (OSS) projects defined by popularity and communication. The aim of this paper is: (I) re-conceptualizing the concept of user interest and broadening our understanding of user interest by incorporating users' post-usage behaviors, (2) examining the effect of various tasks involved in an OSS project's key processes of defect-fixing and feature-enhancement on user interest. The current study found that project popularity is positively influenced by task assignment, task execution and task management. Additionally, user communication was found to be positively impacted by task identification and task execution. The data collected from 1178 OSS projects in a longitudinal manner (at 3 time points over a period of 16 months) confirmed the expectations from TCR and also demonstrated that over time the effects that development of competencies and managing short term cooperative work have on project success might increase, while the impact of identifying market needs and marshalling competencies may not significantly change.

These criteria are based on three specific indicators: intended audiences, relevant topics, and supported operating systems. Results: We show in this short paper that 68% of SourceForge projects are likely reflexive (in the sense described by Raymond). Further, 76% of projects exceeding one million downloads are reflexive, 79% for projects exceeding ten million downloads, and 89% for projects exceeding one hundred million downloads.

BMSCs obtained from rabbits were transfected with bFGF gene-encoding plasmids and proliferation rate and the differentiation marker alkaline phosphatase activity were measured. Following seeding into Bio-Oss collagen and 9-day culture in vitro, the surface morphology of the Bio-Oss was assessed using scanning electron microscopy analysis. Three mandibular defects were induced in the lower border of the bilateral mandibular ramus in each New Zealand white rabbit (total n=6). Three scaffolds, group A (seeded with BMSCs/bFGF), B (seeded with BMSCs/pVAX1) and C (cell-free), which had been cultured in vitro under standard cell culture conditions for 18 days, were implanted into mandibular defects under sterile conditions. Animals were sacrificed by anesthesia overdose 12 weeks following surgery and the scaffolds were extracted for bone mineral density and histological analyses. Results indicate that bFGF was successfully transfected into BMSCs. Proliferation and osteoblast differentiation of BMSCs were stimulated by bFGE: in vitro. No differences were identified in surface morphology for Bio-Oss loaded with variable groups of cells. At week 12 following implantation of Bio-Oss scaffolds, mineralization of BMSCs in Bio-Oss scaffolds was observed to be increased by bFGF. New bone and cartilage formation was revealed in hematoxylin and eosin-stained sections in Bio-Oss scaffolds and was most abundant in group A (BMSCs transfected with bFGF). In the current study, the bFGF gene was transfected into BMSCs and expressed successfully. bFGF promoted proliferation and differentiation of BMSCs in vitro and implantation of bFGF-expressing BMSCs combined with Bio-Oss enhanced new bone regeneration more effectively than traditional methods.","2013-01","2025-05-05 17:03:44","2025-05-05 17:03:44","","99-104","","1","7","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: POB 18179, ATHENS, 116 10, GREECE Publisher: SPANDIDOS PUBL LTD","","","","Bio-Oss; basic fibroblast growth factor; bone marrow stromal cells; \n mandibular defect","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One such project, called Homebase, involved a team of students working with a local Ronald McDonald House to develop volunteer scheduling software. In true open source fashion, this project has since been extended over a number of course iterations, with different clients, and has been adopted at other schools.

Whether a project participant is initiated as a developer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e. g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving developer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e. OSS developers patch submission activities. We use these sets to predict whether a project participant will become a developer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a developer. Further, we find that this is true to the extent that other predictors, e. g. patch submission info, need not be included in the models. In addition, we show that future developers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10% of the three month data's predictions. Finally, we find that it is easier to become a developer earlier in the projects lifecycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2013","2025-05-05 17:03:47","2025-05-05 17:03:47","","340-349","","NA","NA","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","","","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Tech Council Software Engn; Software Improvement\n Grp; Lab Qual Software ISBN: 9780769549811 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Generally, bugs are reported, fixed, verified and closed. However, in some cases bugs have to be re-opened. Re-opened bugs increase maintenance costs, degrade the overall user-perceived quality of the software and lead to unnecessary rework by busy practitioners. In this paper, we study and predict re-opened bugs through a case study on three large open source projects-namely Eclipse, Apache and OpenOffice. We structure our study along four dimensions: (1) the work habits dimension (e.g., the weekday on which the bug was initially closed), (2) the bug report dimension (e.g., the component in which the bug was found) (3) the bug fix dimension (e.g., the amount of time it took to perform the initial fix) and (4) the team dimension (e.g., the experience of the bug fixer). We build decision trees using the aforementioned factors that aim to predict re-opened bugs. We perform top node analysis to determine which factors are the most important indicators of whether or not a bug will be re-opened. Our study shows that the comment text and last status of the bug when it is initially closed are the most important factors related to whether or not a bug will be re-opened. Using a combination of these dimensions, we can build explainable prediction models that can achieve a precision between 52.1-78.6 % and a recall in the range of 70.5-94.1 % when predicting whether a bug will be re-opened. We find that the factors that best indicate which bugs might be re-opened vary based on the project. The comment text is the most important factor for the Eclipse and OpenOffice projects, while the last status is the most important one for Apache. These factors should be closely examined in order to reduce maintenance cost due to re-opened bugs.","2013-10","2025-05-05 17:03:48","2025-05-05 17:03:48","","1005-1042","","5","18","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The utilization of OSS is essential as costs around the world continue to rise for education, institutions must become innovative in the ways they teach and grow Science, Technology, Engineering, & Mathematics (STEM) majors. To do this effectively professors and administrative staff should push toward the utilization of OSS and other available tools to enhance or supplement currently available tools with minimal integration costs. The OSS applications would allow students the ability to learn critical technological skills for success at small fraction of the cost. OSS also provides faculty members the ability to have students dissect source code, analyze network traffic, create virtual instances of real Operating Systems (OSs), and prepare students for low level software development. It is critical that all institutions look at alternatives in providing training and delivering educational material regardless of limitations going forward as the world continues to be more global due to the increased use of technologies everywhere. Through reviewing the available technology, possible implementations of these technologies, and the application of these items in industry could provide a starting point in integrating these tools into academia.

Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects.

This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey.

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-forprofit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-05-05 17:03:56","2025-05-05 17:03:56","","32-39","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: DUNTON TOWER RM 2122, 1125 COLONEL BY DR, OTTAWA, ON K1A 5B6, CANADA Publisher: CARLETON UNIV GRAPHIC SERVICES","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team.

The lack of established metrics makes it difficult to formulate such strategy. While many projects have been formed and created, only a few managed to remain active. With the majority of these projects failing, firms need a reliable set of criteria to assess what makes a project appealing not only to developers but also to visitors, users and commercial sponsors. In this paper, we develop a theoretical model to explore the contextual and causal factors of project attractiveness in inducing activities such as source code contribution, software maintenance, and usage. We test our model with data derived from more than 4000 projects spanning 4 years. Our main findings include that projects' set of conditions such as license restrictiveness and their available resources provide the context that directly influence the amount of work activities observed in the projects. It was also found that indirect and unintended contributions such as recommending software, despite of being non-technical, cannot be ignored for project activeness, diffusion and sustainability. Finally, our analysis provide evidence that higher attractiveness leads to more code-related activities with the downside of slowing down responsiveness to address projects' tasks, such as the implementation of new features and bug fixes. Our model underscores the significance of the reinforcing effects of attractiveness and work activities in open source projects, giving us the opportunity to discuss strategies to manage common traps such as the liability of newness.

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors (”problem solvers”) tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs (”problems”) tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between “core” and “peripheral” members identified exclusively on the basis of their individual level of contribution to the project.

Drawing on theoretical frameworks in organizational behavior and social psychology, her dissertation investigates how conflict arises in voluntary distributed virtual teams such as FOSS, and its impact on group function. The work first explores the emergence and experience of conflict during the life cycle of a project. Different types and sources of conflict are identified, as well as their relationship with group outcomes. Various conflict types are expected to affect group function differently: some conflict sources may present a challenge, while others may prove necessary for successful group function. The dissertation expands theory and research on distributed work, in examining on-going processes of conflict in voluntary teams. This work also informs community design, as understanding conflict antecedents in voluntary virtual teams aids in reducing unproductive conflict and facilitates conflict that spurs innovation.","2013","2025-05-05 17:04:00","2025-05-05 17:04:00","","NA","","NA","NA","","","","WikiSym '13","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450318525 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","performance; distributed work; open source; free software; human factors; conflict; management; satisfaction; virtual teams; voluntary distributed teams","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.","2013-12","2025-05-05 17:04:00","2025-05-05 17:04:00","","361-370","","4","38","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: TWO COMMERCE SQ, 2001 MARKET ST, PHILADELPHIA, PA 19103 USA Publisher: LIPPINCOTT WILLIAMS & WILKINS","","","","qualitative research; health information technology; hospital administration; vendors; open source\n software","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.","2013-01","2025-05-05 17:04:00","2025-05-05 17:04:00","","32–39","","1","3","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Information systems; Information technology; Business And Economics; information retrieval; Open source; Software; Open-source software; Patients; Sustainable development; Social; Information services; Hospitals; Standardization; Public domain; Innovations; Open standard; Records management; electronic health care record; Health care; Health care policy; Health services; Medical records; Medicine; National Health Service; open source framework; openEHR Foundation; persistence; Professionals; Public awareness; Specifications; standards based; Research & development–R&D; 62211:General Medical; Surgical Hospitals","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Drawing an overly technical distinction between these two categories of labor potentially overlooks some important aspects of the processes of capitalist reproduction, particularly the increasingly social character of labor, and as such, a broader definition must be considered. The labor engaged in the production of Free and Open Source Software (FOSS) is illustrative of this need for further examination of the productive-unproductive distinction, for the fact that though FOSS, in some respects, appears tendentially anti-capitalist, in fact, it, and the immaterial labor driving it, has essentially been fully subsumed in the apparatus of capital accumulation.

However, without such an understanding no adequate advice can be derived for managers of FLOSS initiatives on how to foster members' collaboration and retention. Building on lessons learned from the organizational domain this research hypothesizes that spatial, temporal and cultural distances are key factors for FLOSS developers' team integration and project retention.

Over the past 30years, researchers have proposed hypotheses on how software changes and provided evidence that both supports and refutes these hypotheses. To paint a clearer image of the software evolution process, we performed an empirical study on long spans in the lifetime of nine open-source projects. Our analysis covers 705 official releases and a combined 108years of evolution. We first tried to confirm Lehman's eight laws of software evolution on these projects using statistical hypothesis testing. Our findings indicate that only the laws of continuing change and continuing growth are confirmed for all programs, whereas the other six laws are violated by some programs, or can be both confirmed and invalidated, depending on the laws' operational definitions. Second, we analyze the growth rate for projects' development and maintenance branches, and the distribution of software changes. We find similarities in the evolution patterns of the programs we studied, which brings us closer to constructing rigorous models for software evolution.

They were individuals who, despite their affiliation, contributed to the project on their own. They decided which project to join, and their contributions were personal in nature, even when in some cases they were employees of companies with some interests in the project. GNU, the first of such communities, and some others that emerged during the late 1980s and 1990s, followed this pattern. During the 1990s corporate interests started to have a role in some FLOSS communities. Companies hired people from those communities to gain influence, or tasked their employees to contribute to them, again with the idea of influencing their decisions. During the 2000s, corporate communities, in which companies are first-class citizens, have emerged, changing the rules and redefining the role of volunteers and non-affiliated individuals. However, the role of developers, with independence of the company for which they work, is still important even in these communities. This paper addresses this transition from volunteer-based to company-based development communities, and explores the structure and behavior of the latter.","2013-09","2025-05-05 17:04:01","2025-05-05 17:04:01","","173-180","","5, SI","55","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual object motions typically display a level of dynamic regularity reflecting the existence of an underlying physics or biology. Best results are obtained when this local information is exploited. Additionally, if the particle number is known to be approximately constant, a large number of tracking scenarios may be rejected on the basis that they are not compatible with a known maximum particle velocity. This represents information of a global nature, which should ideally be exploited too. Some time ago, we devised an efficient algorithm that exploited both types of information. The tracking task was reduced to a max-flow min-cost problem instance through a novel graph structure that comprised vertices representing objects from three consecutive image frames. The algorithm is explained here for the first time. A user-friendly implementation is provided, and the specific relaxation mechanism responsible for the method's effectiveness is uncovered. The software is particularly competitive for complex dynamics such as dense antiparallel flows, or in situations where object displacements are considerable.

We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications.

Findings - CUSAT has successfully applied DSpace open source software for building a digital library. The digital library has had visits from 78 countries, with the major share from India. The distribution of documents in the digital library is uneven. Past exam question papers share the major part of the collection. The number of research papers, articles and rare documents is less. Originality/value - The study is the first of its type that tries to understand digital library design and development using DSpace open source software in a university environment with a focus on the analysis of distribution of items and measuring the value by usage statistics employing the Google Analytics service. The digital library model can be useful for designing similar systems.","2013","2025-05-05 17:04:02","2025-05-05 17:04:02","","217-225","","2","31","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LIMITED","","","","Open source software; India; Libraries; Digital libraries; DSpace","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of existing software for image-guided neurosurgery for applications in the area of education is limited because of its high cost. For this reason and due to the emergence of new tools based on open source software, reliable algorithms have been developed; these algorithms are able to provide a satisfactory user experience in the use of surgical simulators when compared with to commercial systems. This paper presents the development of two visualization methods useful in neurosurgical training and planning. The first allows the manipulation of volumes through cuts based on regular geometry, while the second allows the visualization of structures through cuts oblique planes. These were developed in 3D Slicer and applied to magnetic resonance imaging for evaluating performance, according to the very needs of the real neurosurgical domain.","2013","2025-05-05 17:04:02","2025-05-05 17:04:02","","NA","","NA","NA","","","","Pan American Health Care Exchanges","","","","","","NA","","","","","","","Backup Publisher: IEEE Morelos Mexico EMB Chapter; IEEE Colombia Sect; IEEE LA EMB\n Chapter; Univ Antioquia; Univ Pontificia Bolivariana; Escuela Ingn\n Antioquia; USM Materialise; EMCO; GBarco; Medinistros; AMAREY; Smart\n Management Choice; Colcafe; Revista Semana; Medellin Convent Bur ISBN: 978-1-4673-6257-3; 978-1-4673-6254-2 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The effect of this shift on project organization and developer collaboration is not well understood. In this paper, we use a theoretical argument to evaluate the appropriateness of using DVC in the context of two very common organization forms in OSS: a dictatorship and a peer group. We find that DVC facilitates large hierarchical communities as well as smaller groups of developers, while CVC allows for consensus-building by a peer group. We also find that the flexibility of DVC systems allows for diverse styles of developer collaboration. With CVC, changes flow up and down (and publicly) via a central repository. In contrast, DVC facilitates collaboration in which work output can flow sideways (and privately) between collaborators, with no repository being inherently more important or central. These sideways flows are a relatively new concept. Developers on the Linux project, who tend to be experienced DVC users, cluster around “sandboxes:” repositories where developers can work together on a particular topic, isolating their changes from other developers. In this work, we focus on two large, mature OSS projects to illustrate these findings. However, we suggest that social media sites like GitHub may engender other original styles of collaboration that deserve further study.","2013","2025-05-05 17:04:02","2025-05-05 17:04:02","","29-32","","NA","NA","","","","RELENG '13","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-4673-6441-6 Place: NA Publisher: IEEE Press","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It was first published in 2009 and since then several related projects are on-going. Its objective is the investigation of strategies for enhancing the accuracy of low-cost single-frequency GPS receivers, mainly by relative positioning with respect to a base station and by a tailored extended Kalman filter working directly on code and phase observations. In this paper, the positioning algorithms implemented in goGPS are presented, emphasizing the modularity of the software design; two specific strategies to support the navigation with low-cost receivers are also proposed and discussed, namely an empirical observation weighting function calibrated on the receiver signal-to-noise ratio and the inclusion of height information from a digital terrain model as an additional observation in the Kalman filter. The former is crucial when working with high-sensitivity receivers, while the latter can significantly improve the positioning in the vertical direction. The overall goGPS positioning accuracy is assessed by comparison with a dual-frequency receiver and with the positioning computed by a standard low-cost receiver. The benefits of the calibrated weighting function and the digital terrain model are investigated by an experiment in a dense urban environment. It comes out that the use of goGPS and low-cost receivers leads to results comparable with those obtained by higher level receivers; goGPS has good performances also in a dense urban environment, where its additional features play an important role.","2013-11","2025-05-05 17:04:02","2025-05-05 17:04:02","","NA","","11","24","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hence it is important to develop software that is easy to modify and is thus maintainable. This paper evaluates the existing Oman and Hagemeister maintainability index model which calculates maintainability index (MI) based on Cyclomatic Complexity, Lines of code and Halsted volume. For this purpose, software metric datasets of Lucene, which is open source software of 163085 lines of code are used, and it is shown that the existing Oman and Hagemeister maintainability index mode model is not a good a predictor of maintainability. A new maintainability index model is proposed with a new set of predictor metrics. The new proposed model is a marked improvement over the existing Oman and Hagemeister maintainability index model.

We propose a methodology-based on situated analyses of a formal design process used in the Python project-to identify the distribution of actual roles (implementation, interactive, group, and design oriented) performed by participants into and between the spaces (defining boundary spaces). This notion of roles is grounded in collaborative design activities performed online by participants. This way, our findings complete the core-periphery model of participation in OSS. Concerning the distribution of roles between spaces, we reveal a map of participation in OSS: The majority of participants are pure discussants, but all participants in the implementation spaces do also act in the discussion space, and few participants act at boundary spaces. Concerning the distribution of roles between participants in the discussion space, we reveal that interactions are structured by a central hub (occupied by key participants) and that, whereas design-oriented roles are spread among all participants, group-oriented roles are performed by one or two participants in the respective spaces and at their boundary. Finally, combination of roles reveals five individual profiles performed by participants. Our approach could be extended to other design situations to explore relationships between forms of participation-in particular, those revealing use-oriented contributions-performance, and quality of the design product.

It applies to well-mixed surface water layers, including the epilimnion of stratified lakes, and the output data are average values over the considered water column. Based on intermediate formation yields from the parent compound via the different photochemical pathways, the software can also predict intermediate formation kinetics and overall yield. APEX is based on a photochemical model that has been validated against available field data of pollutant phototransformation, with good agreement between model predictions and field results. The APEX software makes allowance for different levels of knowledge of a photochemical system. For instance, the absorption spectrum of surface water can be used if known, or otherwise it can be modelled from the values of DOC. Also the direct photolysis quantum yield can be entered as a detailed wavelength trend, as a single value (constant or average), or it can be defined as a variable if unknown.

Different algorithms are available to achieve this, based on pattern recognition, feature based detection, similarity techniques etc. In the present study and implementation, Correlation based methods have been used with a improvement over newly developed technique of identifying and pruning the false points of match. Free and Open Source Software (FOSS) have been used to develop the methodology to reach a wider audience, without any dependency on COTS (Commercially off the shelf) software. Standard deviation from foci of the ellipse of correlated points, is a statistical means of ensuring the best match of the points of interest based on both intensity values and location correspondence. The methodology is developed and standardised by enhancements to meet the registration requirements of remote sensing imagery. Results have shown a performance improvement, nearly matching the visual techniques and have been implemented in remote sensing operational projects. The main advantage of the proposed methodology is its viability in production mode environment. This paper also shows that the visualization capabilities of MapWinGIS, GDAL's image handling abilities and OSSIM's correlation facility can be efficiently integrated to effectively use in remote sensing based production environment.","2014","2025-05-05 17:04:04","2025-05-05 17:04:04","","1121-1128","","NA","40-8","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial\n Information Sciences","","","","","","NA","","","","","","","Backup Publisher: ISPRS Tech Commiss; Int Soc Photogrammetry & Remote Sensing; Indian Soc\n Remote Sensing; Indian Soc Geomat ISBN: NA Place: NA Publisher: NA","","","","NA","","Dadhwal, V.

Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (Von Hippel and Von Krogh, 2003, 2006), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that - (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described. (C) 2013 Elsevier B.V.

The analysis of open source community dynamics is a key capability in risk management practices focused on the integration of FLOSS in all types of organizations. We are conducting research in developing methodologies for managing risks of FLOSS adoption and deployment in various application domains. This paper is about the ability to systematically capture, filter, analyze, reason about, and build theories upon, the behavior of an open source community in combination with the structured elicitation of expert opinions on potential organizational business risk. The novel methodology presented here blends together qualitative and quantitative information as part of a wider analytics platform. The approach combines big data analytics with automatic scripting of scenarios that permits experts to assess risk indicators and business risks in focused tactical and strategic workshops. These workshops generate data that is used to construct Bayesian networks that map data from community risk drivers into statistical distributions that are feeding the platform risk management dashboard. A special feature of this model is that the dynamics of an open source community are tracked using social network metrics that capture the structure of unstructured chat data. The method is illustrated with a running example based on experience gained in implementing our approach in an academic smart environment setting including Moodbile, a Mobile Learning for Moodle (www.moodbile.org). This example is the first in a series of planned experiences in the domain of smart environments with the ultimate goal of deriving a complete risk model in that field.","2014","2025-05-05 17:04:04","2025-05-05 17:04:04","","171-180","","NA","NA","","","","Proceedings International Computer Software and Applications Conference","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Cloud Comp; Korean Inst Informat Scientists &\n Engineers; Iowa State Univ Sci & Technol; IPS; CCF; Malardalen Univ\n Sweden; ABB; Missouri S & T ISBN: 978-1-4799-3574-1 Place: USA Publisher: IEEE Computer Society","","","","social network analysis; FLOSS; OSS; risk management; Bayesian networks; Free Libre Open Source Software; mobile technologies; Moodbile; smart device; smart environment","","Chang, C.

Another important part of spatial epidemiology is testing whether patients suffering from a disease are more, or less, exposed to environmental factors of interest than adequately defined controls. Both approaches involve determining the number of cases and controls (or population at risk) in specific zones. For cluster searches, this often must be done for millions of different zones. Doing this by calculating distances can lead to very lengthy computations. In this work we discuss the computational advantages of geographical grid-based methods, and introduce an open source software (FGBASE) which we have created for this purpose. Methods: Geographical grids based on the Lambert Azimuthal Equal Area projection are well suited for spatial epidemiology because they preserve area: each cell of the grid has the same area. We describe how data is projected onto such a grid, as well as grid-based algorithms for spatial epidemiological data-mining. The software program (FGBASE), that we have developed, implements these grid-based methods. Results: The grid based algorithms perform extremely fast. This is particularly the case for cluster searches. When applied to a cohort of French Type 1 Diabetes (T1D) patients, as an example, the grid based algorithms detected potential clusters in a few seconds on a modern laptop. This compares very favorably to an equivalent cluster search using distance calculations instead of a grid, which took over 4 hours on the same computer. In the case study we discovered 4 potential clusters of T1D cases near the cities of Le Havre, Dunkerque, Toulouse and Nantes. One example of environmental analysis with our software was to study whether a significant association could be found between distance to vineyards with heavy pesticide. None was found. In both examples, the software facilitates the rapid testing of hypotheses. Conclusions: Grid-based algorithms for mining spatial epidemiological data provide advantages in terms of computational complexity thus improving the speed of computations. We believe that these methods and this software tool (FGBASE) will lower the computational barriers to entry for those performing epidemiological research.","2014-10-30","2025-05-05 17:04:06","2025-05-05 17:04:06","","NA","","NA","13","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community - eZ Publish we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm. In addition, the results of our study highlight the central importance of an integrative IT platform in boundary management activities. (C) 2014 Elsevier Ltd.

Voxelized anatomical models are used in numerous applications including the computation of specific absorption rates associated with cell phone transmission energies, radiation therapy, and electromagnetic dosimetry simulation. Other applications range from the study of ergonomics to the design of clothing. Typically, the anatomical pose of a voxelized model is limited by the imaging device used to acquire the source anatomical data; however, absorption of emitted energies and the fit of clothes will change based on anatomic pose. Bender provides an intuitive, workflow-based user-interface to an extensible framework for changing the pose of anatomic models. Bender is implemented as a customized version of 3D Slicer, an image analysis and visualization framework that is widely used in the medical computing research community. The currently available repositioning methods in Bender are based on computer-graphics techniques for rigging, skinning, and resampling voxelized anatomical models. In this paper we present the software and compare two resampling methods: a novel extension to dual quaternions and finite element modeling (FEM) techniques. We show that FEM can be used to quickly and effectively resample repositioned anatomic models.","2014","2025-05-05 17:04:06","2025-05-05 17:04:06","","203-210","","NA","8789","","","","Lecture Notes in Computer Science","","","","","","NA","","","","","","","Backup Publisher: Inria, SHACRA Team; Imperial Coll London, SiMMS Grp; IHU Strasbourg ISBN: 978-3-319-12057-7; 978-3-319-12056-0 Place: NA Publisher: NA","","","","NA","","Bello, F.; Cotin, S.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nevertheless, OSS, when viewed as a value creation process rather than `free' software, provides businesses with value through access to knowledge and innovation capacity resident in online communities. This conceptualisation, which we label `strategic open source' requires firms to rethink their strategy and processes as there is a shift in focus from ownership to openness and collaboration with external parties. Nonetheless, the emergence of OSS poses a puzzle for conceptions of organisational theory. Therefore, a theorising process is needed in order to develop a deeper understanding of how value is created and captured with OSS. Using a field study of eleven European firms, this paper explores the creation and capture of business value from strategic open source. The findings reveal that while decision makers look to open innovation initiatives like OSS for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.

Materials and Methods: b-TCP-collagen composite material was fabricated by mixing b-TCP granules having a particle size of 0.15 to 0.8 mm and 75% porosity, with bovine dermis-derived soluble collagen sponge. The dry weight ratio of b-TCP granules-to-collagen ratios was 4:1. Bio-Oss Collagen or the b-TCP-collagen composite was used to fill a 5.0 mm-diameter calvarial defect in rats. The defects were evaluated by histological and histomorphological analyses of decalcified histological sections with hematoxylin and eosin staining 6 and 10 weeks, respectively, after surgery. Results: The defect implanted with the b-TCP composite contained immature bone structures with dense connective tissue in contrast to the abundant fibrous tissue, but no trabecular structure was observed within the defect implanted with Bio-Oss Collagen at 6 weeks postoperatively. Eventually, the defect filled with the b-TCP composite was covered with dense, continuous, mature bone tissue with complete replacement of the graft material. However, in defects filled with Bio-Oss Collagen, only dense connective tissue, containing limited amounts of immature trabecular bone and abundant remnant Bio-Oss particles, was observed. Histomorphological analysis revealed that the b-TCP composite caused greater tissue augmentation with a larger volume of bone tissue observed in the defect and greater bioabsorption of remnant material than Bio-Oss Collagen. Conclusion: These results indicated that the b-TCP composite has greater osteoconductivity and better biodegradation properties than Bio-Oss Collagen; these properties of the b-TCP-collagen composite complimented bone formation and remodeling.","2014-04","2025-05-05 17:04:07","2025-05-05 17:04:07","","202-211","","2","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Results from a meta-analysis of all clinical trials (up to 2011) indicated a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. Our objective of this study is to build a virtual breast phantom lab in the public domain that can be used for rigorous imaging testing of this kind. Main thrust of this work is to streamline biomedical ultrasound simulations in conjunction with anatomically complex (software) phantoms by leveraging existing open source software packages including K-wave or Field II (acoustic simulation), VTK (data visualization and processing), FEBio (biomechanical deformation) and Tetgen (mesh generation). The integration of these four open source packages was based on a simple message-passing scheme to facilitate its use among imaging scientists. In this study, we demonstrated that a complex and heterogeneous (virtual) breast phantom can be derived from medical imaging data, i.e. publically available Visible Human Project data through US National Institutes of Health. Three volumes of interest were selected from the proposed virtual breast phantom to perform acoustic simulations using a virtual linear array transducer (6MHz and 80% bandwidth). Our initial results showed that simulated B-mode images accurately represented the underlying complex but known medium. In order to demonstrate applications in elastography, the virtual breast phantom was also deformed using finite element simulations. The resultant simulated strain image depicted complex patterns that were normally seen in clinical data. In conclusion, the proposed virtual software infrastructure can perform sophisticated ultrasound simulations in conjunction with complex and heterogeneous media. It is our intent that, in the future, the proposed virtual software infrastructure will be available to the research community for use in creation complex imaging benchmark tests for algorithm testing and validation. Furthermore, the proposed virtual platform can also be tailored to meet specific research needs by potential users themselves in an open science fashion. Collectively, these activities will accelerate development of ultrasound imaging including elastography.","2014","2025-05-05 17:04:07","2025-05-05 17:04:07","","1841-1844","","NA","NA","","","","IEEE International Ultrasonics Symposium","","","","","","NA","","","","","","","Backup Publisher: IEEE ISBN: 978-1-4799-7049-0 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of eXe Learning and Xerte can be generated courses which have a similar structure to that of the classic course, but that can be approached as a web page. Information is structured so that they comply with the requirements of a weaving technology. The teacher can generate in the same course, a number of subsections which the student can learn in the same order or according to his need. Can be attached multimedia materials, its own teacher, and reference may be made to the existing materials on the Internet. The course can be saved in different formats, so it can be loaded on an e-learning plafform. The two open source software is built on different platforms (Linux, Windows) for a fairly large number of variations. The development of eXe Learning has been stopped, Xerte reached at version 3.0 (beta). Both programs are developed by the universities (from New Zealand and England). If eXe is based on his experience during use, Xerte requires some knowledge of programming into Action Script. Both software has bibliographic resources quite confined, but can also be used easily as soon as it gains experience. The software's have the possibility to generate tests, but in the case of eXe Learning the answers that have the disadvantage that the order is the same and it is necessary to use special software to test for generating (like Hot Potatoes).

Apparently, this is also true for open-sourced software – most users would not compile the available source, and implicitly trust that the available binaries have been compiled from the published source code (i.e., no backdoor has been inserted in the binary). To verify that the official binaries indeed correspond to the released source, one can compile the source of a given application, and then compare the locally generated binaries with the developer-provided official ones. However, such simple verification is non-trivial to achieve in practice, as modern compilers, and more generally, toolchains used in software packaging, have not been designed with verifiability in mind. Rather, the output of compilers is often dependent on parameters that can be strongly tied to the building environment. In this paper, we analyze a widely-used encryption tool, TrueCrypt, to verify its official binary with the corresponding source. We first manually replicate a close match to the official binaries of sixteen most recent versions of TrueCrypt for Windows up to v7.1a, and then explain the remaining differences that can solely be attributed to non-determinism in the build process. Our analysis provides the missing guarantee on official binaries that they are indeed backdoor-free, and makes audits on TrueCrypt's source code more meaningful. Also, we uncover several sources of non-determinism in TrueCrypt's compilation process; these findings may help create future verifiable build processes.","2014","2025-05-05 17:04:08","2025-05-05 17:04:08","","16–25","","NA","NA","","","","ACSAC '14","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450330053 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","tor; debian; bitcoin; deterministic build; reproducible build; TrueCrypt","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These data ground theories of cognitive function in anatomy, and with the emergence of graph theoretical analyses in neuroscience, there is high demand for these data to be consolidated into large-scale connection matrices (”macroconnectomes”). Because manual review of the anatomical literature is time consuming and error prone, computational solutions are needed to accomplish this task. Here we describe the “CoCoTools” open-source Python library, which automates collection and integration of macaque connectivity data for visualization and graph theory analysis. CoCoTools both interfaces with the CoCoMac database, which houses a vast amount of annotated tracer results from 100 years (1905-2005) of neuroanatomical research, and implements coordinate-free registration algorithms, which allow studies that use different parcellations of the brain to be translated into a single graph. We show that using CoCoTools to translate all of the data stored in CoCoMac produces graphs with properties consistent with what is known about global brain organization. Moreover, in addition to describing CoCoTools' processing pipeline, we provide worked examples, tutorials, links to on-line documentation, and detailed appendices to aid scientists interested in using CoCoTools to gather and analyze CoCoMac data.","2014-04","2025-05-05 17:04:08","2025-05-05 17:04:08","","722-745","","4","26","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Metabolites are generally annotated with various database or structure based identifiers. Metabolite annotations in metabolic reconstructions may be incorrect or incomplete and thus need to be updated prior to their use. Genome-scale metabolic reconstructions generally include hundreds of metabolites. Manually updating annotations is therefore highly laborious. This prompted us to look for open-source software applications that could facilitate automatic updating of annotations by mapping between available metabolite identifiers. We identified three applications developed for the metabolomics and chemical informatics communities as potential solutions. The applications were MetMask, the Chemical Translation System, and UniChem. The first implements a “metabolite masking” strategy for mapping between identifiers whereas the latter two implement different versions of an InChI based strategy. Here we evaluated the suitability of these applications for the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We applied the best suited application to updating identifiers in Recon 2, the latest reconstruction of human metabolism. Results: All three applications enabled partially automatic updating of metabolite identifiers, but significant manual effort was still required to fully update identifiers. We were able to reduce this manual effort by searching for new identifiers using multiple types of information about metabolites. When multiple types of information were combined, the Chemical Translation System enabled us to update over 3,500 metabolite identifiers in Recon 2. All but approximately 200 identifiers were updated automatically. Conclusions: We found that an InChI based application such as the Chemical Translation System was better suited to the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We identified several features, however, that could be added to such an application in order to tailor it to this task.","2014-01-27","2025-05-05 17:04:08","2025-05-05 17:04:08","","NA","","NA","6","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software. For this purpose, we consider open source project management and game software. We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., conceptual) and solution domain (i.e., design) models.

This result occurs if the investment cost function is superadditive. We find that government contribution leads to larger crowding-in effects than subsidizing market entry if the price elasticity of demand with respect to the private good is large relative to the one with respect to the public good.

The quantification of tumor heterogeneity with molecular images, by analyzing the local or global variation in the spatial arrangements of pixel intensity with texture analysis, possesses a great clinical potential for treatment planning and prognosis. To address the lack of available software for computing the tumor heterogeneity on the public domain, we develop a software package, namely, Chang-Gung Image Texture Analysis (CGITA) toolbox, and provide it to the research community as a free, open-source project. Methods. With a user-friendly graphical interface, CGITA provides users with an easy way to compute more than seventy heterogeneity indices. To test and demonstrate the usefulness of CGITA, we used a small cohort of eighteen locally advanced oral cavity (ORC) cancer patients treated with definitive radiotherapies. Results. In our case study of ORC data, we found that more than ten of the current implemented heterogeneity indices outperformed SUVmean for outcome prediction in the ROC analysis with a higher area under curve (AUC). Heterogeneity indices provide a better area under the curve up to 0.9 than the SUVmean and TLG (0.6 and 0.52, resp.). Conclusions. CGITA is a free and open-source software package to quantify tumor heterogeneity from molecular images. CGITA is available for free for academic use at http://code.google.com/p/cgita.","2014","2025-05-05 17:04:09","2025-05-05 17:04:09","","NA","","NA","2014","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With recent trends such as mass customization or Industry 4.0, there is an increasing need for automation systems to be dynamic. Changing parts of the software of today's automation systems, however, typically requires rebooting the controller, which makes software updates a complex and costly endeavor often despised by operators. This article presents an approach to updating the software of automation systems at runtime without disrupting the system's operation. This is achieved with a combination of a component-based architecture, cyclic application execution, and a state transfer mechanism between the original and the updated version of a component. We validate our solution with a case study in which we update the control algorithm of a magnetic levitation device running at cycles of 1 kHz without dropping the ball.","2014","2025-05-05 17:04:09","2025-05-05 17:04:09","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Univ Politecnica Catalunya; IEEE Ind Elect Soc; IEEE ISBN: 978-1-4799-4845-1 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer. Finally, we develop a committer-identification model to assist OSS projects identifying future committers.","2014","2025-05-05 17:04:10","2025-05-05 17:04:10","","47-56","","NA","NA","","","","International Conference on Quality Software","","","","","","English","","","","","","","Backup Publisher: IEEE Reliabil Soc; UT Dallas; IEEE Comp Soc ISBN: 978-1-4799-7197-8 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper uses new internal quality characteristics for selecting OSS that can be added to the dimensions of DeLone and McLean information systems' model. Through this study, the quality characteristics are organized in a two level hierarchy, which list characteristics and sub-characteristics that are interconnected with three main dimensions: system quality, information quality and service quality. These characteristic dimensions are tailored to the criteria having been built from literature study and standard for software quality and guidelines.

Based on information from publicly available data, we investigated the investment behavior of 37 VCs investing in 45 OSS projects. To understand how these venture capitalists try to reduce their perception of uncertainty and risk, we developed a 2 x 2 matrix of diffrerent investment approaches. While the X-axis represents the average age of a community/OSS product at the time of investment, the Y-axis reflects the average round of a venture capitalist's entry. This exploratory study illustrates how venture capitalists limit the level of risk inherent in certain OSS investments and results in a number of implications for communities seeking for external funds as well as for investing firms.","2014-08","2025-05-05 17:04:10","2025-05-05 17:04:10","","NA","","4","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While prior research has explored the communal nature of open source software development among individual users, little research has explored whether these sharing concepts are also present in organizational use of open source software products. This study uses a theory integration approach to develop some initial insight into the differences between users and non-users of open source software. This study observed three groups of factors from six case studies of information sharing in the context of organizational open source software use. These factors were integrated with prior research in order to understand the physical and managerial barriers to, and enablers of, open source. The study proposes that open source users have more extensive knowledge sharing and teamwork practices in place, and are more tolerant of risk. The study also argues that open source users depended less on external technology support services but have more extensive information technology ( IT) support structures.

There is an ever-present need for readily available information and sophisticated means of communication. As a result, information and communication technologies are being deployed for application in various fields of endeavour some of which include virtual offices. A virtual office is essentially a simulated corporate environment that gives subscribers access to collaborative work related features, which act as a means of improving the way work is carried out in an organisation. Several organisations opt for the software services rendered by virtual offices because of their cost effectiveness and tendency to boost the collective productivity of these organisations. For reasons as such, the existence of virtual office software suites have become rampant, but the availability of its services are at a cost. This paper reports the design and implementation of an Educational Virtual Office using Free and Open-Source Software (FOSS) to relieve corporate organisations of the costly burdens of existing proprietary virtual office software. Tools used in achieving this feat are Drupal Web Content Management System (WCMS), readily available FOSS and a couple of other freeware, intelligently integrated to form a composite suite. The developed educational virtual office suite was deployed in the Department of Electrical and Information Engineering of Covenant University. A usability (user satisfaction) test was conducted. Analysis of the test results showed that questions related to user satisfaction scored more “Strongly Agree” and “Agree” points than “Disagree” and “Strongly Disagree”. This is a pointer to the fact that features such as the GUI of the web application and its navigation proved to have little or no challenges as at when the tests were carried out. Deployment of the developed educational virtual office suite has the significant advantage of low cost in comparison with proprietary virtual office suites with similar functionality. The fact that the suite was developed entirely using FOSS gives it all the attendant advantages that accrue from the employment of same from the system design bottom-Up. Such advantages as easy access to source code, which engenders easy upgrade of the component parts, come naturally.","2014","2025-05-05 17:04:11","2025-05-05 17:04:11","","5018-5027","","NA","NA","","","","EDULEARN Proceedings","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-84-617-0557-3 Place: NA Publisher: NA","","","","NA","","Chova, L.

The degree distributions of links in both the in-directed and out-directed dependency networks follow Zipf's law for the intermediate nodes, but the heavily linked nodes and the poorly linked nodes deviate from this trend and exhibit finite-size effects. The finite-size parameters make a quantitative distinction between the in-directed and out-directed networks. For the out-degree distribution, the initial condition for a dynamic evolution corresponds to the limiting count of the most heavily linked nodes that the out-directed network can finally have. The number of nodes contributing out-directed links grows with every generation of software release, but this growth ultimately saturates toward a terminal value, due to the finiteness of semantic possibilities in the network.","2014","2025-05-05 17:04:11","2025-05-05 17:04:11","","71-92","","1","23","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.","2014","2025-05-05 17:04:11","2025-05-05 17:04:11","","401-412","","NA","NA","","","","FSE 2014","","","","","","English","","","","","","","Backup Publisher: Assoc Comp Machinery Special Interest Grp Software Engn; CVIC SE; NSF;\n Microsoft Res; Huawei; Neusoft; Siemens; Yonyou; Hong Kong Univ Sci &\n Technol; Google; Radica; Samsung Res Amer; IBM Res; TCL; CCC ISBN: 978-1-4503-3056-5 Place: 1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES Publisher: ASSOC COMPUTING MACHINERY","","","","sequence analysis; layered network; structural complexity; Time-series; \n Markov entropy","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The method EVfold broke new ground using mean-field Direct Coupling Analysis (EVfold-mfDCA); the method PSICOV applied a related concept by estimating a sparse inverse covariance matrix. Both methods (EVfold-mfDCA and PSICOV) are publicly available, but both require too much CPU time for interactive applications. On top, EVfold-mfDCA depends on proprietary software. Results: Here, we present FreeContact, a fast, open source implementation of EVfold-mfDCA and PSICOV. On a test set of 140 proteins, FreeContact was almost eight times faster than PSICOV without decreasing prediction performance. The EVfold-mfDCA implementation of FreeContact was over 220 times faster than PSICOV with negligible performance decrease. EVfold-mfDCA was unavailable for testing due to its dependency on proprietary software. FreeContact is implemented as the free C++ library “libfreecontact”, complete with command line tool “freecontact”, as well as Perl and Python modules. All components are available as Debian packages. FreeContact supports the BioXSD format for interoperability.

This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software-continue to-rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. Trust (i.e. full write-access) is `backgrounded' by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.","2014-06","2025-05-05 17:04:12","2025-05-05 17:04:12","","157-169","","2","16","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Philosophy; Community; Social research; Collaboration; Open-source software; Wikipedia; Trust; Social networks; Public domain; Reputations; Reputation; Vandalism","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the emergence and popularity growth of social Q&A sites such as the StackExchange network (e.g., StackOverflow), this is beginning to change. Such sites offer different socio-technical incentives to their participants than mailing lists do, e.g., rich web environments to store and manage content collaboratively, or a place to showcase their knowledge and expertise more vividly to peers or potential recruiters. A key difference between StackExchange and mailing lists is gamification, i.e., StackExchange participants compete to obtain reputation points and badges. In this paper, we use a case study of R (a widely-used tool for data analysis) to investigate how mailing list participation has evolved since the launch of StackExchange. Our main contribution is the assembly of a joint data set from the two sources, in which participants in both the textttr-help mailing list and StackExchange are identifiable. This permits their activities to be linked across the two resources and also over time. With this data set we found that user support activities show a strong shift away from textttr-help. In particular, mailing list experts are migrating to StackExchange, where their behaviour is different. First, participants active both on textttr-help and on StackExchange are more active than those who focus exclusively on only one of the two. Second, they provide faster answers on StackExchange than on textttr-help, suggesting they are motivated by the emphgamified environment. To our knowledge, our study is the first to directly chart the changes in behaviour of specific contributors as they migrate into gamified environments, and has important implications for knowledge management in software engineering.","2014","2025-05-05 17:04:13","2025-05-05 17:04:13","","342–354","","NA","NA","","","","CSCW '14","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450325400 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source; crowdsourced knowledge; gamification.; mailing lists; a; social q&","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is unclear whether these motivations have any actual impact on OSS project success. <u>Goal:</u> To identify how an OSS developer's reputation affects the outcome of his/her code review requests. <u>Method:</u> We conducted a social network analysis (SNA) of the code review data from eight popular OSS projects. Working on the assumption that core developers have better reputation than peripheral developers, we developed an approach, Core Identification using K-means (CIK) to divide the OSS developers into core and periphery groups based on six SNA centrality measures. We then compared the outcome of the code review process for members of the two groups. <u>Results:</u> The results suggest that the core developers receive quicker first feedback on their review request, complete the review process in shorter time, and are more likely to have their code changes accepted into the project codebase.

We identify several linguistically shallow, content-based heuristics that correlate with the classification and investigate the extent to which they can serve as independent classification criteria. Then, we train machine-learning classifiers on these heuristics. We experiment with a wide range of settings, such as different learners, excluding some heuristics and adding unigram features of various parts-of-speech and frequency.

Global optimization methods, which provide a robust methodology, and metaheuristics in particular have proven to be the most efficient methods for many applications. Despite their utility, there is a limited availability of metaheuristic tools. Results: We present MEIGO, an R and Matlab optimization toolbox (also available in Python via a wrapper of the R version), that implements metaheuristics capable of solving diverse problems arising in systems biology and bioinformatics. The toolbox includes the enhanced scatter search method (eSS) for continuous nonlinear programming (cNLP) and mixed-integer programming (MINLP) problems, and variable neighborhood search (VNS) for Integer Programming (IP) problems. Additionally, the R version includes BayesFit for parameter estimation by Bayesian inference. The eSS and VNS methods can be run on a single-thread or in parallel using a cooperative strategy. The code is supplied under GPLv3 and is available at http://www.iim.csic.es/similar to gingproc/meigo.html. Documentation and examples are included. The R package has been submitted to BioConductor. We evaluate MEIGO against optimization benchmarks, and illustrate its applicability to a series of case studies in bioinformatics and systems biology where it outperforms other state-of-the-art methods. Conclusions: MEIGO provides a free, open-source platform for optimization that can be applied to multiple domains of systems biology and bioinformatics. It includes efficient state of the art metaheuristics, and its open and modular structure allows the addition of further methods.","2014-05-10","2025-05-05 17:04:14","2025-05-05 17:04:14","","NA","","NA","15","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently, there exists no working operationalization available that can be used to determine the health of open source ecosystems. Health is typically looked at from a project scope, not from an ecosystem scope. Objectives: With such an operationalization, stakeholders can make better decisions on whether to invest in an ecosystem: developers can select the healthiest ecosystem to join, keystone organizers can establish which governance techniques are effective, and end-users can select ecosystems that are robust, will live long, and prosper. Method: Design research is used to create the health operationalization. The evaluation step is done using four ecosystem health projects from literature. Results: The Open Source Ecosystem Health Operationalization is provided, which establishes the health of a complete software ecosystem, using the data from collections of open source projects that belong to the ecosystem. Conclusion: The groundwork is done, by providing a summary of research challenges, for more research in ecosystem health.

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving.

These models describe the consequences of adopting one such strategy or another: which are the business goals that are supported, which are the resources that emerge, etc. To this aim, we first enumerate the main existing OSS adoption strategies, next we formulate an ontology that comprises the activities and resources that characterise these strategies, then based on the experience of 5 industrial partners of the RISCOSS EU-funded project, we explore how these elements are managed in each strategy and formulate the corresponding model using the i* framework.","2014","2025-05-05 17:04:15","2025-05-05 17:04:15","","349-362","","NA","8824","","","","Lecture Notes in Computer Science","","","","","","NA","","","","","","","Backup Publisher: Penn State Univ; Singapore Management Univ TCS, iCity Lab; BYU, Marriott\n Sch Management; Aalto Univ; QUT ISBN: 978-3-319-12206-9; 978-3-319-12205-2 Place: NA Publisher: NA","","","","NA","","Yu, E.; Dobbie, G.; Jarke, M.; Purao, S.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However empirical studies on modularity of OSS systems have resulted in confusing results. To account for underlying mechanisms of those confusing results, we systematically examine widely studied OSS projects. Based on our systematic review on technical and organizational structures, we suggest that organizational circumstances of OSS production are at least in a continuum of tightly-coupled and loosely- coupled organizational circumstances of production in which both geographically distributed volunteers and paid developers with organizational ties work together (albeit separately over time). Furthermore, organizational circumstances of OSS production appear to be dynamic, as firms move in and out of OSS production communities over time. In essence we argue that the reason for the confusing empirical results was a persistent assumption that organizational circumstances of OSS production are static or unitary; rather what matters is the organizational circumstances of production in any episode of contribution. This research agenda paper proposes future inquiries to develop a comprehensive picture of ecological shift in different levels of system modularity and organizational circumstances of OSS production over time and through episodes.","2014","2025-05-05 17:04:15","2025-05-05 17:04:15","","NA","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-0-692-25320-5 Place: P.O.

Continuous awareness of the product release status is required. Release readiness is a time-dependent attribute of the status of the product release, which aggregates the degree of satisfaction of a portfolio of release process and product measures.Goal: At different stages of a release cycle, the goal is to understand frequencies and pattern of occurrence of factors affecting project success by restricting the status of release readiness (called bottlenecks).Method: As a form of explorative case study research, we analyzed ten open source software (OSS) projects taken from the GitHub repository. As a retrospective study covering a period of 28 weeks, we monitored eight release readiness attributes and identified their impact on release readiness over time across the ten projects.Results: Feature completion rate, Bug fixing rate, and Features implemented were observed as the most frequent bottlenecks. The most frequent transition between bottlenecks is from Pull-request completion rate to Bug fixing rate. With the exception of Pull-request completion rate, no significant differences were found in occurrence of bottleneck factors between early and late stage of the release cycle.Conclusions: We received an initial understanding of the most frequent bottleneck factors for release readiness and their likelihood of subsequent occurrence. This is intended to guide the effort spent on improving release engineering.","2014","2025-05-05 17:04:15","2025-05-05 17:04:15","","NA","","NA","NA","","","","ESEM '14","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450327749 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","release readiness; bottleneck identification; exploratory case study; retrospective analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage. The empirical investigation in this paper shows that the switching points of stages have meaningful associations with the release dates.","2014","2025-05-05 17:04:15","2025-05-05 17:04:15","","207-212","","NA","NA","","","","EUROMICRO Conference Proceedings","","","","","","English","","","","","","","Backup Publisher: Elsevier Informat & Software Technol Journal; EDALab s r l; Euromicro ISBN: 978-1-4799-5795-8 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","Rabiser, R.; Torkar, R.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Based on the results of the ISG/OS-1 study, the MAP regimen (methotrexate [MTX], doxorubicin [ADM] and cisplatin [CDP] with the addition of ifosfamide [IFO] in poor-responder patients) was investigated in patients with nonmetastatic osteosarcoma of the extremity (ISG/OS-Oss study). Patients and methods. Compared with the ISG/OS-1 study (cumulative doses: ADM 420 mg/m(2), MTX 120 g/m(2), CDP 600 mg/m(2), IFO 30 g/m(2)), the ISG/OS-Oss study reduced the number of MTX cycles from 10 to 5 (cumulative MTX dose: 60 g/m(2)) in order to diminish treatment duration and toxicity. Results. From January 2007 to June 2011, 171 patients (median age 16 years, 60% males) were registered. The limb salvage rate was 94% and the good pathologic response rate 51% (these figures were 92% and 48%, respectively, in the ISG/OS-1 study). At a median follow-up of 39 months (range, 4-80), the 5-year overall survival rate was 80% (95% CI, 73%-87%) and the event-free survival was 50% (95% CI, 39%-59%). For comparison, the 5-year overall and event-free survival rates in ISG/OS-1 were 73% (95% CI, 65%-81%) and 64% (95% CI, 56%-73%), respectively. Conclusions. This study confirms that in nonmetastatic osteosarcoma of the extremity, conservative surgery in more than 90% and a good pathologic response rate of 50% can be expected with primary chemotherapy based on the MAP regimen. The response and resection rates in the ISG/OS-Oss study are in the same range as those of the previous study, whereas the event-free survival is lower than that previously achieved. Since the only difference between the two studies was the cumulative dose of postoperatively given MTX, our data support the importance of the cumulative dose of MTX in the MAP regimen.","2014-12","2025-05-05 17:04:15","2025-05-05 17:04:15","","612-619","","6","100","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1 OLIVERS YARD, 55 CITY ROAD, LONDON EC1Y 1SP, ENGLAND Publisher: SAGE PUBLICATIONS LTD","","","","methotrexate; neoadjuvant chemotherapy; osteosarcoma; tumor necrosis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We also found that self-efficacy did not change significantly, even when participants encountered significant barriers or setbacks. The top 3 barriers were lack of communication, installation issues, and documentation issues. We found that asking for and receiving help, and avoiding difficult development environments were more likely to lead to success.

Otherwise, uncontrolled complexity makes the maintenance and enhancement process lengthy, more costly and some times it can contribute to the system abandonment.

The functionality of the software includes setpoint control, data logging, and protocol execution. Auxiliary hardware can be easily integrated and controlled through an integrated plugin interface without altering existing software. Simple experimental protocols can be entered as a CSV scripting file, and a Python-based protocol execution model is included for more demanding conditional experimental control. The software was designed to be a more flexible and free open source alternative to the commercially available solution.

In doing so, it offers new insights into the association between open innovation and diversification. We rely on arguments inspired by the literature and evidence collected through interviews with OSS SMEs' top managers to investigate factors that favor or hinder within-industry diversification. First, in line with the mainstream diversification literature, we focus attention on the role of firm size. Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products.

In doing so, it offers new insights into the association between open innovation and diversification. We rely on arguments inspired by the literature and evidence collected through interviews with OSS SMEs' top managers to investigate factors that favor or hinder within-industry diversification. First, in line with the mainstream diversification literature, we focus attention on the role of firm size. Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products. Furthermore, we provide preliminary evidence that the practice of authorizing firm programmers to contribute autonomously to OSS projects of their own choice during working hours may be positively associated to within-industry diversification only if OSS SMEs possess adequate internal technological resources.

Although OSS is usually free of charge, its diffusion remains limited, Should government intervene to promote the diffusion of OSS, and offer potential adopters some learning or financial support? This paper examines whether public subsidies for OSS are socially desirable. and how the extent of compatibility between OSS and proprietary software (PS) might influence the optimal subsidy offered. We consider a mixed duopoly model in which a PS company competes with an OSS community. Users are heterogeneous in their ability to use OSS, and their utility depends on the number of users who adopt the same or compatible software (existence of network externalities). Four situations are distinguished: full compatibility between OSS and PS, full incompatibility, and one-way compatibility (either only OSS or PS is compatible). We show that if the government places more weight on consumer surplus. public subsidies are welfare-enhancing. But the optimal subsidy level is larger with full compatibility and PS compatibility than full incompatibility and OSS compatibility. These results suggest that government policy towards OSS should be conditional on the degree of compatibility between PS and OSS.","2014","2025-05-05 17:04:17","2025-05-05 17:04:17","","1174-1184","","2","34","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The use of minimization reduces differences that might arise by chance between the study arms in the distribution of patient characteristics such as gender, ethnicity and age. However, unlike randomization, minimization requires real time assessment of each new participant with respect to the preceding distribution of relevant participant characteristics within the different arms of the study. For multi-site studies, this necessitates centralized computational analysis that is shared between all study locations. Unfortunately, there is no suitable freely available open source or free software that can be used for this purpose. OxMaR was developed to enable researchers in any location to use minimization for patient allocation and to access the minimization algorithm using any device that can connect to the internet such as a desktop computer, tablet or mobile phone. The software is complete in itself and requires no special packages or libraries to be installed. It is simple to set up and run over the internet using online facilities which are very low cost or even free to the user. Importantly, it provides real time information on allocation to the study lead or administrator and generates real time distributed backups with each allocation. OxMaR can readily be modified and customised and can also be used for standard randomization. It has been extensively tested and has been used successfully in a low budget multi-centre study. Hitherto, the logistical difficulties involved in minimization have precluded its use in many small studies and this software should allow more widespread use of minimization which should lead to studies with better matched control and experimental arms. OxMaR should be particularly valuable in low resource settings.","2014-10-29","2025-05-05 17:04:17","2025-05-05 17:04:17","","NA","","10","9","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Bone tissue regeneration remains one of the most important issues of maxillofacial surgery. Restoration of the native structure of bone after osteoplasty is directly related to the process of revascularization, because the growing of blood vessels into the graft is a precondition for transport of osteogenic cells, growth factors necessary for further osteogenesis. Objectives. To determine the peculiarities of bone tissue regeneration after osteoplasty with BioOss (R) and compare it with autological bone graft. Material and Methods. Experimental study was conducted on 60 white rats (males, aged 6- 8 month, weight 270- 380 g). The area of dorsal surface of the shinbone was used for implantation. After opening access to the bone surface, one 2 mm-diameter defect was formed on each shinbone. One of those bone defects was filled with osteoplastic material and the opposite was healing under a blood clot. After that the wound in soft tissues was closed in layer by layer. The osteocalcin level in blood serum was determined by ELISA employing N-MID Osteocalcin (R) ELISA (IDS) test system(enzyme immunological test for the quantitative measurement of osteocalcin). The peculiarities of revascularization were studied by histologic method. Histologic specimen were stained using Schmorl technique (thionine with phenol trinitrate) and natural hematoxylin-eosin. Results. Mean values of osteocalcin concentration after BioOss implantation ranged from 2 +/- 0.06 ng/mL to 3.65 +/- 0.09 ng/mL; after autological bone graft transplant - from 1.88 +/- 0.09 ng/mLto 2.2 +/- 0.09 ng/mL. In the case of Bio-Oss use, the most active revascularization processes and the highest level of osteocalcin were registered on day 60. In the case of autological bone graft use, the quantity of blood vessels increased steadily and equally during the whole period of the experiment. Conclusions. According to the obtained results, the use of autological bone graft and Bio-Oss osteoplastic material increases bone formation and revascularization activity and improves the bone structure unlike when healing took place under the blood clot","2014-12","2025-05-05 17:04:18","2025-05-05 17:04:18","","458-467","","4","51","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To develop an empirical understanding of OSS peer review, we examine the review policies of 25 OSS projects and study the archival records of six large, mature, successful OSS projects. We extract a series of measures based on those used in traditional inspection experiments. We measure the frequency of review, the size of the contribution under review, the level of participation during review, the experience and expertise of the individuals involved in the review, the review interval, and the number of issues discussed during review. We create statistical models of the review efficiency, review interval, and effectiveness, the issues discussed during review, to determine which measures have the largest impact on review efficacy. We find that OSS peer reviews are conducted asynchronously by empowered experts who focus on changes that are in their area of expertise. Reviewers provide timely, regular feedback on small changes.

The purpose of present study was to fully characterize our anorganic bone, InterOss (R), by physical and chemical methods and to compare it with another anorganic bone, Bio-Oss (R) that has been commercially distributed in dental bone graft substitute market since 1995. InterOss (R) anorganic bone had been successfully prepared by chemical treatment (NaOH and H2O2) and low temperature (350 degrees C) annealing process with an extremely low heating rate (<0.3 degrees C min(-1)). Commercially available Bio-Oss (R) anorganic bone was chosen for comparison. The physical and chemical analysis indicated that the pore structure, microstructure, phase structure, and chemical composition of InterOss (R) is substantially equivalent to that of Bio-Oss (R). The BET analysis also showed that the inner surface area of InterOss (R) is comparatively higher than that of Bio-Oss (R). Specially, the protein analysis showed that the content of residual protein of InterOss (R) is relatively lower than that of Bio-Oss (R). Based on an equivalency to Bio-Oss (R) in terms of physical and chemical characterization with both higher inner surface area and lower residual protein content, the InterOss (R) can be a promising candidate as dental bone grafting material in periodontal and maxillofacial surgery.

Organizations are also now adopting OSS, despite some reservations, particularly about the quality issues. Stability of software is one of the main features in software quality management that needs to be understood and accurately predicted. It deals with the impact resulting from software changes and argues that stable components lead to a cost-effective software evolution. Changes are most common phenomena present in OSS in comparison to proprietary software. This makes OSS system evolution a rich context to study and predict stability. Our objective in this work is to build stability prediction models that are not only accurate but also interpretable, that is, able to explain the link between the architectural aspects of a software component and its stability behavior in the context of OSS. Therefore, we propose a new approach based on classifiers combination capable of preserving prediction interpretability. Our approach is classifier-structure dependent. Therefore, we propose a particular solution for combining Bayesian classifiers in order to derive a more accurate composite classifier that preserves interpretability. This solution is implemented using a genetic algorithm and applied in the context of an OSS large-scale system, namely the standard Java API. The empirical results show that our approach outperforms state-of-the-art approaches from both machine learning and software engineering.","2014-04","2025-05-05 17:04:18","2025-05-05 17:04:18","","NA","","1","5","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Bayesian classifiers; genetic algorithm; Software stability prediction","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In GitHub, developers are allowed to fork repositories and copy repositories without asking for permission, which make contribution to projects much easier than it has ever been. It is significant to predict the number of forks for open source software projects. The prediction can help GitHub to recommend popular projects, and guide developers to find projects which are likely to succeed and worthy of their contribution. In this paper, we use stepwise regression and design a model to predict the number of forks for open source software projects. Then we collect datasets of 1,000 repositories through GitHub's APIs. We use datasets of 700 repositories to compute the weight of attributes and realize the model. Then we use other 300 repositories to verify the prediction accuracy of our model. Advantages of our model include: (1) Some attributes used in our model are new. This is because GitHub is different from traditional open source software platforms and has some new features. These new features are used to build our model. (2) Our model uses project information within t month after its creation, and predicts the number of forks in the month T (t < T). It allows users to set the combination of time parameters and satisfy their own needs. (3) Our model predicts the exact number of forks, rather than the range of the number of forks (4) Experiments show that our model has high prediction accuracy. For example, we use project information with 3 months to prediction the number of forks in month 6 after its creation. The correlation coefficient is as high as 0.992, and the median number of absolute difference between prediction value and actual value is only 1.8. It shows that the predicted number of forks is very close to the actual number of forks. Our model also has high prediction accuracy when we set other time parameters.","2014","2025-05-05 17:04:19","2025-05-05 17:04:19","","40-47","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-4503-2965-1 Place: 1515 BROADWAY, NEW YORK, NY 10036-9998 USA Publisher: ASSOC COMPUTING MACHINERY","","","","Open Source Software; Fork","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many projects leverage the contribution of outsiders, and the sustainability of the project relies on retaining some of these new-comers. This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review, (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects, (iii) 24 responses to a questionnaire sent to 9 OSS projects, and (iv) semi-structured interviews with 36 sub-jects from 14 different projects, including newcomers and experi-enced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practi-tioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteris-tics, reception issues, orientation, technical hurdles, and docu-mentation problems. We could observe recurrent barriers evi-denced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.","2014","2025-05-05 17:04:19","2025-05-05 17:04:19","","51–60","","NA","NA","","","","ARES '14","","","","","","English","","","","","","","Backup Publisher: Univ Fed Alagoas; Ufal; CAPES; Conselho Nacl Desenvolvimento Cientifico\n & Tecnologico; Ines; Google; Inst Fed Alagoas; Aloo Telecom; Alagoas\n Governo Estado, Secretaria Estado Turismo; Maceio Convent & Visitors\n Bur; Soc Brasileira Computacao; Josi Mendes Consultoria & Eventos;\n Transamerica Turismo; IEEE Comp Soc ISBN: 9781479942237 Place: USA Publisher: IEEE Computer Society","","","","newcomers; open source software; systematic literature review; onboarding; qualitative analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thus, it is unique software that computes these tensor-based indices. These descriptors, establish relations for two, three, and four atoms by using several (dis) similarity metrics or multimetrics, matrix transformations, cutoffs, local calculations and aggregation operators. The theoretical background of these N-linear indices is also presented. The QuBiLS-MIDAS software was developed in the Java programming language and employs the Chemical Development Kit library for the manipulation of the chemical structures and the calculation of the atomic properties. This software is composed by a desktop user-friendly interface and an Abstract Programming Interface library. The former was created to simplify the configuration of the different options of the MDs, whereas the library was designed to allow its easy integration to other software for chemoinformatics applications. This program provides functionalities for data cleaning tasks and for batch processing of the molecular indices. In addition, it offers parallel calculation of the MDs through the use of all available processors in current computers. The studies of complexity of the main algorithms demonstrate that these were efficiently implemented with respect to their trivial implementation. Lastly, the performance tests reveal that this software has a suitable behavior when the amount of processors is increased. Therefore, the QuBiLS-MIDAS software constitutes a useful application for the computation of the molecular indices based on N-linear algebraic maps and it can be used freely to perform chemoinformatics studies.

Open-source software allows members of the public to study, customize, and operate their own local copies of the software and source code, often without monetary fees. As such, releasing SAGES as open-source software assures prospective users that they retain complete control over the health data collected by SAGES-based systems, and aligns well with the model of self-sustainability intended for the operation of SAGES systems in resource-limited settings. Preparing two SAGES tools, OpenESSENCE and SAGES Mobile, for release as open-source software projects entailed a multifaceted, months-long effort that spanned policy, technical, and community considerations. This article describes the issues, trade-offs, and decisions that were addressed leading up to the successful open-source release of OpenESSENCE and SAGES Mobile in June 2013.

The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented. (C) 2013 Elsevier Ltd. APM and IPMA.

This pervasive adoption is not without risks for an industry that has experienced significant failures in product quality, timelines and delivery costs. Exhaustive testing of any software system and, specifically, of open source software components is usually not feasible due to limitations in time and resources. In risk-based testing approach test cases are selected and scheduled based on software risk analysis. This research introduces the strategy of risk-based adaptive testing of OSS by combining information on the OSS community ecosystem with risk-driven tests selection and scheduling strategy. A key feature of the proposed approach is the monitoring and analysis of OSS community dynamics, including chats and email communications, blogs, repositories of bugs and fixes, and more. The community and its dynamics are then monitored to detect anomaly communication between the community members.

It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.","2014","2025-05-05 17:04:20","2025-05-05 17:04:20","","477-512","","4","34","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: HOWARD HOUSE, WAGON LANE, BINGLEY BD16 1WA, W YORKSHIRE, ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD","","","","Open source software; Enterprise resource planning; Case study; IT risk management; SME; IT\n adoption","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of FOSS (Free and Open Source Software) systems, many upgrade errors cannot be discovered by current upgrade managers and then a system upgrade can potentially lead the system to an inconsistent and incoherent state. Objective: The objective of this paper is to propose an approach to simulate the upgrade of complex systems in order to predict errors before they affect the real system. Method: The approach promotes the use of model-driven engineering techniques to simulate the upgrade of complex systems. The basic idea is to have a model-based description of the system to be upgraded and to make use of model transformations to perform the upgrade on a source model so to obtain a target model representing the state of the upgraded system. Results: We provide an implementation of the simulator, which is tailored to FOSS systems. The architecture of the simulator is distribution independent so that it can be easily instantiated to specific distributions. The simulator takes into account also pre and post-installation scripts that equip each distribution package. This feature is extremely important since maintainer scripts are full-fledged programs that are run with system administration rights. Conclusions: The paper shows the kind of errors the simulator is able to predict before upgrading the real system, and how the approach improves the state of the art of package managers while integrated in real Linux distribution installations.

Then why is it that software architecture modeling is so conspicuously missing from popular online open source code repositories? How can including visual documentation improve the overall quality of open source software projects? Our goal is to answer both of these questions and bridge the gap between traditional software engineering best practices and open source development by applying a software architecture documentation methodology using Unified Modeling Language, called 5W1H Re-Doc, on a real open source project for managing identity and access, MITREid Connect. We analyze the effect of a model-driven software engineering approach on collaboration of open source contributors, quality of specification conformance, and state-of-the-art of architecture modeling.

Traditionally, RE has been considered as a centralized, collocated, and phase-specific process. However, in open-source software (OSS) development environment, the core RE activities are iterative and dynamic and follow a rather decentralized software engineering paradigm. This crosscutting characteristic of open-source RE can be conceptualized using the “Twin Peaks” model that weaves RE together with software architecture. Although many weaving mechanisms have been proposed in recent years, lack of theoretical underpinning limits a mechanism's applicability and usefulness in different scenarios. In this research proposal, we hypothesize stakeholders' social interaction as an ecologically valid weaving mechanism of the “Twin Peaks” in open-source RE. We further outline a concrete research plan to examine the generalizability of this weaving mechanism for three activities: requirements identification, requirements implementation, and creativity in RE. Carrying out this research plan will enable us to gain valuable insights to generate guidelines for enhancing software engineering practice in relevant areas.","2014","2025-05-05 17:04:21","2025-05-05 17:04:21","","467-472","","NA","NA","","","","International Requirements Engineering Conference","","","","","","NA","","","","","","","Backup Publisher: IEEE; Iowa State Univ, Coll Liberal Arts & Sci; VISITBLEKINGESE;\n BLEKINGE TEKNISKA HOGSKOLA; CISCO; LANSSTYRELSEN BLEKINGE LAN;\n VISITKARLSKRONA ISBN: 978-1-4799-3033-3 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Using this perspective, we examine how FLOSS developers' reputation among members within and beyond the project community affects their projects' ability to attract new developers.

Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

A project aiming to prove that free alternatives such as FOSS are a worthy alternative was born. A videogame was made from the ground up using only FOSS and Freeware solutions, along with free assets made available to the community for free, filling the gaps where the team had no expert to solve (such as sound effects).

OSS is a complicated social process to understand. OSS is a multi-faceted phenomenon including code, a licensing structure, a community, development best practices, a method of diffusion. However, the current OSS collaborative researches place too much emphasis on collaborative behaviors, but ignore the study on collaborative process. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and level of collaboration between collaborators. Based on the definition of three types of contact behavior, this paper presents an approach to measuring the contact relationship intensity. Based on introducing and improving TF-IDF (term frequency-inverse document frequency), this paper presents the methods for calculating tag weights and work similarity between collaborators. Finally, by evaluating the model using data from the OSS websitewww.Codeplex.com, we verify that our model outperforms conventional models in both describing and forecasting collaborative behavior.","2014","2025-05-05 17:04:23","2025-05-05 17:04:23","","77-86","","1","15","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Social network analysis; Behavior; China; Studies; Collaboration; Virtual communities; Open-source software; Consumer behavior; Electronic commerce; Knowledge sharing; Cooperation; Social networks; 5240:Software & systems; 9130:Experiment/theoretical treatment; Public domain; 9179:Asia & the Pacific; Reputations; Social network; 7100:Market research; Collaborative network; Business And Economics–International Commerce; 45411:Electronic Shopping; Mail-Order Houses","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose TRG (tag recommendation based on semantic graph), a novel approach to discovering and enriching tags of open source software. Firstly, we propose a semantic graph to model the semantic correlations between tags and the words in software descriptions. Then based on the graph, we design an effective algorithm to recommend tags for software.

Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment.

In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory.According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another.The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.","2014-04","2025-05-05 17:04:24","2025-05-05 17:04:24","","127–143","","2","39","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Open source; Software; Open-source software; Open Source Software; Product development; Institutional theory; Public domain; 51321:Software Publishers; Software industry; Copyleft vs Copyright; Institutional Entrepreneurship; IP Protection; Legitimacy; Organizational field; Organizational Field Boundaries; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Three configurations were identified: Defined Community, Open Community, and Authoritarian Community. Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team. The results provide guidance for practitioners about how to combine 19 identified governance mechanisms into effective project governance that stimulates productive participation.

Despite the highly distributed and dynamic nature of OSS development, it is often described in unitary, monolithic terms - an unfortunate situation which masks considerable variance across OSS development processes. Therefore we explore reasons for systematic variance in these processes so as to enable more effective OSS development practices. Drawing on theory of distributed cognition, we develop a language of cognitive translations, which occur within and across distributed social arrangements and structural conditions of sharing knowledge. This language provides micro-foundations for understanding how different modes of OSS development emerge. Through examining how generative characteristics of social and structural distributions in OSS shape distinct development pathways, we propose a theoretically derived typology explaining the characteristics, dynamics, and conditions for success of different modes of OSS development.","2014","2025-05-05 17:04:24","2025-05-05 17:04:24","","4568-4577","","NA","NA","","","","Proceedings of the Annual Hawaii International Conference on System\n Sciences","","","","","","English","","","","","","","Backup Publisher: Univ Hawaii, Shidler Coll Business; IEEE Comp Soc ISBN: 978-1-4799-2504-9 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","Open Source Software; Emergence; Modes; Typology","","Sprague, R.

The RSS was scoured firstly in strongly alkaline electrolyzed water (SAEW, pH >= 11.5) consisting mainly of hydroxyl ions by boiling for 30 min and then treated by the traditional scouring procedure (without alkaline compounds), resulting in refined silk floss. The recycled SAEW containing sericin was separated by ultrafiltration into a retentate with a range of high molecular mass values accounting for 10% (w/w) of the cocoon shell and the filtrate was separated by nanofiltration into a purified H2O filtrate and a retentate containing oligopeptides and free amino acids, which can be used directly as food additives or in biological growth media. The ultrafiltration retentate was hydrolyzed by papain under three different conditions into three groups of sericin peptides with high, middle or low molecular mass. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and gel permeation high-performance liquid chromatography (GP-HPLC) showed the molecular mass of these sericin peptides was in the range 0.2-60, 0.2 -30 and 0.2-15 kDa. These clean products have a variety of applications, including coating materials for surface modification, cell culture media and food additives. The procedure described here could be applied to the manufacture of silk floss quilts and the process of refining raw silk, which results in three clean products of the silk protein fibroin (i.e. stripped of sericin) and reduces environmental pollution from scouring waste containing sericin.

Behind the expansion, there exist OSS development communities, where voluntary engineers dedicate their time and effort for the improvement. Considering development engineers in the companies as input resources, it is important to investigate the output of business growth. In this study, we conducted questionnaire survey to Japanese IT companies in 2013, and then analyzed the present state and relation between OSS utilization and development contribution. Our study revealed that Japanese IT companies are rather free riders of OSS, the volume of development contributions are far less than that of utilization. With regard to the effect on the business growth, the results of correlation analysis implicate that OSS utilization is related to the sales growth in the present term and that development contribution is related to the future growth of the employee number in the company. In order to explore the direct effect on the business growth, we constructed the models of multiple-logistic and logistic analyses, however, no direct and explicit determinants are found from the results of the analyses. Our research endeavors to investigate the OSS effect on the business growth are still on the way, but it is meaningful to provide the present state in numbers and hopefully this will lay some foundation for further study in this field.","2014","2025-05-05 17:04:25","2025-05-05 17:04:25","","1–8","","NA","NA","","","","OpenSym '14","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450330169 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Open Source Software; Business Growth; Development Contribution; Utilization","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Methods which deliver composite data reflecting the mean values of biomarkers from cell populations risk losing subpopulation dynamics that reflect the heterogeneity of the studied biological system. In keeping with this, traditional approaches are being replaced by, or supported with, more sophisticated forms of cellular assay developed to allow assessment by high-content microscopy. These assays potentially generate large numbers of images of fluorescent biomarkers, which enabled by accompanying proprietary software packages, allows for multi-parametric measurements per cell. However, the relatively high capital costs and overspecialization of many of these devices have prevented their accessibility to many investigators. Described here is a universally applicable workflow for the quantification of multiple fluorescent marker intensities from specific subcellular regions of individual cells suitable for use with images from most fluorescent microscopes. Key to this workflow is the implementation of the freely available Cell Profiler software(1) to distinguish individual cells in these images, segment them into defined subcellular regions and deliver fluorescence marker intensity values specific to these regions. The extraction of individual cell intensity values from image data is the central purpose of this workflow and will be illustrated with the analysis of control data from a siRNA screen for G1 checkpoint regulators in adherent human cells. However, the workflow presented here can be applied to analysis of data from other means of cell perturbation (e.g., compound screens) and other forms of fluorescence based cellular markers and thus should be useful for a wide range of laboratories.","2014-12","2025-05-05 17:04:26","2025-05-05 17:04:26","","NA","","94","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we focused on continuity of OSS project, as it is one of the most important factors for users to make a decision. In order to evaluate continuity, we proposed a growth model of OSS project, which is based on the size and activity of OSS Project. We evaluated the growth model using information retrieved from OSS communities from both OSS community sites and source code repositories. (C) 2015 The Authors.

They are made of thousands of components (software packages) evolving rapidly without centralized coordination. The upgrade of FOSS systems is managed by meta-installers, which solve package dependencies and conflicts and lead the system to a new system configuration by installing or removing packages. Current tools are able to predict a very limited set of upgrade faults before deployment, and this leaves a wide range of faults unpredicted. In this paper, we focus on faults that remain unpredicted, for example, missing packages, packages that are not properly installed, and missing services, with the aim of providing a solution for them. Specifically, in this paper, we propose a model-driven approach and supporting tools to prevent specific classes of system configuration faults before performing the real upgrade. Once the system configuration is represented as a model, the configuration model is evaluated by means of queries, each devoted to discover a specific class of faults. The approach is intrinsically extensible so that user communities can add new queries when new classes of faults are identified. The approach has been validated by executing the fault detector on configuration models in which faults have been intentionally injected and by analyzing produced results.

The result is a theory that small businesses founded by free/libre software advocates have three characteristics of social entrepreneurships. First, social benefit is prioritized over wealth creation. Second, the business's social mission is not incidental but is furthered through its for-pro fit activities, rather than supported by the company's profits.

Despite the substantive economic and efficiency-related implications of OSS adoption, there is surprisingly little research into the determinants of the diffusion of OSS across public sector jurisdictions. In this article we explore the variation in OSS adoption among Dutch local administrations. The Dutch central government adopted a policy to stimulate the use of OSS in the public sector, but the non-mandatory character of the policy resulted in great differences in the degree of adoption of OSS at the local level. Using data from a new survey of municipalities in the Netherlands and proportional odds statistical models to analyze the data, we show that the degree of OSS adoption crucially depends on the presence of boundary spanners and political commitment within the local government On the other hand, oft-suspected factors like financial stress and jurisdiction size have no discernible effects. Our findings have implications for understanding the spread of OSS in the public sector and for public policies designed to encourage OSS diffusion.

Therefore, organizations are increasingly becoming OSS adopters, either as a result of a strategic decision or because it is almost unavoidable nowadays, given the fact that most commercial software also relies at some extent in OSS infrastructure. The way in which organizations adopt OSS affects and shapes their businesses. Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. In this paper, we propose to model OSS adoption strategies using a goal-oriented notation, in which different actors state their objectives and dependencies on each other. These models describe the consequences of adopting one such strategy or another: which are the strategic and operational goals that are supported, which are the resources that emerge, etc. The models rely on an OSS ontology, built upon a systematic literature review, which comprises the activities and resources that characterize these strategies. Different OSS adoption strategy models arrange these ontology elements in diverse ways. In order to assess which is the OSS adoption strategy that better fits the organization needs, the notion of model coverage is introduced, which allows to measure the degree of concordance among every strategy with the model of the organization by comparing the respective models. The approach is illustrated with an example of application in a big telecommunications company. (C) 2015 Elsevier B.V.

In this work, we collected data through online surveys answered by workers in IT companies in the state of Minas Gerais, Brazil. The proposed model for determining the impact of each factor on the adoption of OSS and on the business model practiced by IT companies was evaluated by using structural equations. The results show that three groups of factors impact the way of OSS adoption. Organizational and technological factors are the most relevant, whereas for business models only environmental factors are relevant. The most relevant technological factor identified is ""reduced hardware and software costs""; the most relevant organizational factor is ""flexibility of IT structure""; and the most relevant environmental factor is ""reports of successful use of OSS"".

Although developers may find useful software assets to reuse from OSS for their projects, they usually experience difficulties in solving problems that occur while integrating the assets to their own software. We investigated data from major open source environments such as Sourceforge. net and GitHub, and learned that there is a common pattern of solving reuse-related problems in OSS. To analyze the pattern in detail, we have developed an ontological model to formally represent the symptoms and causes of the reuse-related problems, and the correlations between them. Based on this model, we collected data from Sourceforge. net, and built a knowledge base for the most common problem type. We extracted the core types of symptoms and causes for the problem type and calculated the number of correlations between the types of symptoms and causes. We found that there exist correlations between the symptoms and causes that are extracted from the discussion threads for the problem type, and about 60% of them are statistically significant. We also conducted a study to understand the effective timing of recommending solutions to the developers by analyzing the recall rates of finding the causes of the problems in a timeline. We figured that most of the important causes of a problem are discussed at the beginning of the forum discussion. This leads us to the conclusion that recommending the causes of a problem early by using our knowledge framework may help developers spend less amount of time to solve the problem (around 50% less time than solving the problem without using our framework).","2015-08","2025-05-05 17:04:28","2025-05-05 17:04:28","","1077-1103","","6","25","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It divides the sample sets of dependent variables into different subsets (or subclusters) through a series of cutting and merging operations based upon the theory of multivariate analysis of variance (MANOVA). The modeling results are given by a cluster tree, which includes both intermediate and leaf subclusters as well as the flow paths from the root of the tree to each leaf subcluster specified by a series of cutting and merging actions.

Our goal is to analyze the connectivity structure of the social networks of contributors and to investigate the effect of the different social ties structures on developers' overall productivity to OSS projects. We, first, analyze the general structure of the social networks, e.g., graph distances and the degree distribution of the social networks. Our social network structure analysis confirms a power-law degree distribution and small-world characteristics. However, the degree mixing pattern shows that high degree nodes tend to connect more with low degree nodes suggesting a collaboration between experts and newbie developers. We further conduct the same analysis on affiliation networks and find that contributors tend to participate in projects of similar team sizes. Second, we study the correlation between various social factors (e.g., closeness and betweenness centrality, clustering coefficient and tie strength) and the productivity of the contributors in terms of the amount of contribution and commitment to OSS projects. The analysis is conducted under the contexts of global and local networks, where a global network analysis considers a developer's connectivity in the whole OSS community network, whereas a local network analysis considers a developer's connectivity within a team network that is affiliated to a project. The analysis demonstrates evident influence of the social factors on the developers' overall productivity.","2015","2025-05-05 17:04:29","2025-05-05 17:04:29","","57-75","","NA","NA","","","","Lecture Notes in Social Networks","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-3-319-19003-7; 978-3-319-19002-0 Place: NA Publisher: NA","","","","NA","","Kazienko, P.; Chawla, N.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project's time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project's progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.","2015-06","2025-05-05 17:04:29","2025-05-05 17:04:29","","1-23","","2","7","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS","","","","FLOSS; OSS; Open source project; survival; OSS popularity; ordinal regression; OSS success; \n hazard","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although the study on the construction of cranio-maxillofacial implant based on computer modelling and advanced biomaterial are growing rapidly from other parts of the world, however, in Malaysia is scanty, especially with open source application.

Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio [finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to mitigate the impact of natural hazards on European economies and societies, improved risk assessment, and management needs to be pursued. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models have become an important part of flood risk management (FRM). In this context, free and open-source (FOSS) geospatial models provide better and more complete information to stakeholders regarding their compliance with the Flood Directive (2007/60/EC) for effective and collaborative FRM. A geospatial model is an essential tool to address the European challenge for comprehensive and sustainable FRM because it allows for the use of integrated social and economic quantitative risk outcomes in a spatio-temporal domain. Moreover, a FOSS model can support governance processes using an interactive, transparent and collaborative approach, providing a meaningful experience that both promotes learning and generates knowledge through a process of guided discovery regarding flood risk management. This article aims to organize the available knowledge and characteristics of the methods available to give operational recommendations and principles that can support authorities, local entities, and the stakeholders involved in decision-making with regard to flood risk management in their compliance with the Floods Directive (2007/60/EC).","2015-12","2025-05-05 17:04:30","2025-05-05 17:04:30","","2704-2727","","4","4","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","open-source; GIS; flood risk management; flood risk model","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Cavities were formed, by a homemade mold, on untouched third molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities' surface and their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three materials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential morphology. Moreover, variations were observed when comparing cells numbers on cavity's filling versus the surrounding dentine disc. The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss.

Whether a project participant is initiated as a committer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e.g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving committer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different Apache Software Foundation OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e., OSS developers' patch submission activities. We use these sets to predict whether a project participant will become a committer, and to characterize their socialization patterns around the time of becoming committer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a committer. Further, we find that this is true to the extent that other predictors, e.g., patch submission info, need not be included in the models. In addition, we show that future committers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10 % of the three month data's predictions. Interestingly, we find that on average, for each project, one's level of socialization ramps up before the time of becoming a committer. After obtaining committer status, their social behavior is more individualized, falling into few distinct modes of behavior. In a significant number of projects, immediately after the initiation there is a notable social cooling-off period. Finally, we find that it is easier to become a committer earlier in the projects life cycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.","2015-10","2025-05-05 17:04:31","2025-05-05 17:04:31","","1318-1353","","5","20","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER","","","","Open source software; Logistic regression; Email social networks; \n Developer initiation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Individual developers contribute to developing the software, but do not hold the copyright to appropriate its value. This raises questions regarding motives behind such effort. We provide an integrated model of developers' incentives to describe OSS development and compare restrictive OSS licenses that force all modifications to be kept open with non-restrictive OSS licenses that allow proprietary ownership of modified works. Different incentives govern effort provision at different stages of the software development process. We show that open-source licenses can provide socially valuable software when a proprietary license fails to do so. We also show that restrictive OSS licenses generate greater effort provision in the design stage of software development relative to non-restrictive licenses. Endogenizing licensing choice, we find that a project leader chooses a non-restrictive OSS license if reputational concerns drive developers' incentives, a proprietary license when there is a large population of users in the market and a restrictive OSS license if user population is small but reputational benefit is high. Our results resonate well with empirical findings and suggest additional testable implications about the relationship between licensing and software project characteristics. Finally, we also find that the market under-provides restrictive OSS licenses relative to the efficient level, suggesting the need for subsidizing restrictive licenses in some cases.","2015-07","2025-05-05 17:04:31","2025-05-05 17:04:31","","1381-1416","","3","15","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Studies; Open source; Software engineering; Software license; Open-source software; Licenses; License; Software development; 9130:Experiment/theoretical treatment; Public domain; 8302:Software & computer services industry; Developer; Proprietary; Licensing; 1130:Economic theory; Public good; Economic models; Incentive; Business And Economics–Economic Systems And Theories; Economic History","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The way the OSS products are developed and distributed is questioning the right to exclude others from using the goods and introduces the right to distribute and modify software for free. The economic impact of the Open Source Software contribution is significant, it has been estimated that it represents c.a. 30% of the software market. There is an increasing interest in studying OSS communities, however there have been a small number of studies investigating the general role of the OSS in the economic growth. Therefore the lack of theory linking the economic growth and OSS contribution represents the main theoretical problem of this paper. The goal of this article is to prove that the existence of OSS communities increases the quantity of non-rival and non-excludable goods, which - according to endogenous model of growth - leads to economic growth. Additionally the study findings undermine the neoclassical theory of property rights in terms of non-rival and non-excludable goods. The structure of the paper is organized as follows. In section 1 the article focuses on the literature addressing the role of the non-rival and non-excludable goods in the theory of growth and theory of property rights. Section 2, contains the literature review of the OSS socio-economic phenomena and argues that the neoclassical theory of rights is inadequate to explain OSS market existence. Section 3 of the paper summarizes the main conclusions and discusses the general motivation behind the creation of the non-excludable and non-rival goods as well as the diminishing role of the egoism as the origin of the economic growth. From the methodological point of view the paper represents a literature review and a critical analysis of the endogenous growth theory and the theory of property rights.","2015","2025-05-05 17:04:31","2025-05-05 17:04:31","","69-76","","2","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects.

One of the features provided by most issue-trackers is the possibility to define a set of labels/tags to classify the issues and, at least in theory, facilitate their management. Nevertheless, there is little empirical evidence to confirm that taking the time to categorize new issues has indeed a beneficial impact on the project evolution. In this paper we analyze a population of more than three million of GitHub projects and give some insights on how labels are used in them. Our preliminary results reveal that, even if the label mechanism is scarcely used, using labels favors the resolution of issues. Our analysis also suggests that not all projects use labels in the same way (e.g., for some labels are only a way to prioritize the project while others use them to signal their temporal evolution as they move along in the development workflow). Further research is needed to precisely characterize these label “families” and learn more the ideal application scenarios for each of them.","2015","2025-05-05 17:04:33","2025-05-05 17:04:33","","550-554","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Polytechnique Montreal, Dept Genie Informatique Genie Logiciel; Google\n Montreal; IEEE Comp Soc; Reengineering Forum; SAP Montreal Labs; Techn\n Council Software Engn; Tourisme Montreal ISBN: 978-1-4799-8469-5 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In biology, these systems have a direct relation to critical processes ranging from the movement of actin or assembly of viruses at cellular interfaces to the growth of amyloid plaques in neuro-degenerative diseases. In technology and applied sciences, synthetic macromolecules or fibrous objects such as carbon nanotubes are involved in countless applications. Accessing their intrinsic properties at the single molecule level, such as their molecular conformations or intrinsic stiffness, is central to the understanding of these systems, their properties, and the design of related applications. In this Perspective we introduce FiberApp a new tracking and analysis software based on a cascade of algorithms describing structural and topological features of objects characterized by a very high length-to-width aspect ratio, generally described as “fiber-like objects”. The program operates on images from any microscopic source (atomic force or transmission electron microscopy, optical, fluorescence, confocal, etc.), acquiring the spatial coordinates of objects by a semiautomated tracking procedure based on A* pathfinding algorithm followed by the application of active contour models and generating virtually any statistical, topological, and graphical output derivable from these coordinates. Demonstrative features of the software include statistical polymer physics analysis of fiber conformations, height, bond and pair correlation functions, mean-squared end-to-end distance and midpoint displacement, 2D order parameter, excess kurtosis, fractal exponent, height profile and its discrete Fourier transform, orientation, length, height, curvature, and kink angle distributions, providing an unprecedented structural description of filamentous synthetic and biological objects.","2015-03-10","2025-05-05 17:04:33","2025-05-05 17:04:33","","1269-1280","","5","48","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here, we evaluated biopsies of grafted bone with a mixture of autologous bone and Bio-Oss((R)) or BoneCeramic((R)) after two different healing time periods to understand the molecular process underlying bone formation after MSFE. Material and methodsSeven patients, following a bilateral split-mouth design model and needing a MSFE to allow implant placement, were recruited for this study. Right or left sinuses were grafted with autologous maxillary bone combined either with Bio-Oss((R)) or BoneCeramic((R)), respectively. Twenty biopsies were taken at the time of implant insertion after 4-5months or 6-8months of MSFE, and analyzed by micro-computed tomography (microCT) and gene-expression analysis. ResultsMicroCT analysis revealed no differences in the morphometric parameters or BMD either after 4-5months or 6-8months of MSFE between Bio-Oss((R)) and BoneCeramic((R)). At molecular level, a higher expression of bone forming gene Runx2 was observed after 4-5months of MSFE in the Bio-Oss((R)) compared with the BoneCeramic((R)) group. ConclusionsOur results indicate that differences found at the molecular level between Bio-Oss((R)) and BoneCeramic((R)) are not translated to important differences in the 3D microstructure and BMD of the grafted bone.","2015-06","2025-05-05 17:04:34","2025-05-05 17:04:34","","727-735","","6","26","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","bone graft; clinical study; dental implant; gene expression; micro-computed tomography (microCT); maxillary\n sinus floor elevation (MSFE)","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware.

A matrix differentiating four types of OSSDPs: firm- versus community-initiated projects and one participating firm (single-vendor projects) versus many firms (multivendor projects), and accompanying hypotheses regarding a firm's participation for each type are developed. Using data from 83 Eclipse projects to test the hypotheses, findings indicate that (1) firms more actively employ both leadership and resource deployment in firm-initiated projects than in community-initiated ones and (2) firms are more likely to use resource deployment control over leadership control in multivendor projects.

This is multi-platform software developed in the Java programming language, designed with a remarkably user-friendly graphical interface for the computation of a collection of information-theoretic functions adapted for rank-based unsupervised and supervised feature selection tasks. A total of 20 feature selection parameters are presented, with the unsupervised and supervised frameworks represented by 10 approaches in each case. Several information-theoretic parameters traditionally used as molecular descriptors (MDs) are adapted for use as unsupervised rank-based feature selection methods. On the other hand, a generalization scheme for the previously defined differential Shannon's entropy is discussed, as well as the introduction of Jeffreys information measure for supervised feature selection. Moreover, well-known information-theoretic feature selection parameters, such as information gain, gain ratio, and symmetrical uncertainty are incorporated to the IMMAN software (http://mobiosd-hub.com/imman-soft/), following an equal-interval discretization approach. IMMAN offers data pre-processing functionalities, such as missing values processing, dataset partitioning, and browsing. Moreover, single parameter or ensemble (multi-criteria) ranking options are provided. Consequently, this software is suitable for tasks like dimensionality reduction, feature ranking, as well as comparative diversity analysis of data matrices. Simple examples of applications performed with this program are presented. A comparative study between IMMAN and WEKA feature selection tools using the Arcene dataset was performed, demonstrating similar behavior. In addition, it is revealed that the use of IMMAN unsupervised feature selection methods improves the performance of both IMMAN and WEKA supervised algorithms.

They provide critical information and enhance environmental integrity in planning and development of GHG mitigation policy. The characteristics of a high quality inventory are that it follows good practice according to the IPCC guidelines. The key components of good practice are that the inventory is transparent to others, has accurate and complete emissions estimates for all gases, sources and sinks; has consistent application of methods across time; and is comparable to inventories from other countries [1]. While developed countries struggle with implementation of good practice, most can produce reasonably high quality inventories [2]. However, the task is more challenging in low lying pacific island countries. Some of the specific challenges include: lack of clarity on roles and responsibilities of agencies in preparing inventories; small teams with limited resources; difficulty in retaining expertise; incomplete or non-existent activity data; inconsistent data between inventories; absence of an archiving system for previous inventories; no QA/QC plan [3]. As part of the UN-REDD Programme project on “Strengthening Regional Support to National Forest Monitoring Systems for REDD+ in the Pacific” a Regional Monitoring System has been developed to support low lying pacific island countries (Republic of Palau, Tuvalu, Cook Islands, Tonga, Republic of Kiribati, and Federated States of Micronesia). Using the Republic of Palau as a case study, we present this system and focus on four main challenges; 1) improving activity data compilation through systematic land use assessment 2) application of simple land use mapping algorithms 3) application of a regional geo-spatial portal to support improved data management 4) application of open-source land use analysis systems to help manage and analyze inventory data.","2015","2025-05-05 17:04:35","2025-05-05 17:04:35","","3361-3364","","NA","NA","","","","IEEE International Symposium on Geoscience and Remote Sensing IGARSS","","","","","","NA","","","","","","","Backup Publisher: IEEE ISBN: 978-1-4799-7929-5 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The degree of restriction of the license and an indicator of success of free software were related: the time between stages, that is, the time spent to evolve through the various stages of development.

These communities' survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSS coach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project.

This increasing attention is a result of the remarkable growth in the number of OSS applications in recent years. Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach - To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents' opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings - The analysis of the data reveals that the individual participant's satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value - Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members' satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.","2015","2025-05-05 17:04:36","2025-05-05 17:04:36","","791-813","","4","19","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Online communities; Motivation; Community; Data analysis; Qualitative research; Collaboration; Virtual communities; Open source; Online community; Software; Open-source software; Product development; Management; Quantitative research; Factor analysis; Regression analysis; Knowledge management; Knowledge sharing; Project management; Public domain; Surveys & questionnaires; Literature reviews; Correlation analysis; Explicit knowledge; Open source software communities; Open source software projects; Tacit knowledge; Test procedures; Work environment; Business And Economics–Management; Research & development–R&D","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Instead, we are in a new age where software is developed by a networked community of individuals and organizations, which base their relations to each other on mutual interest. Paradoxically, recent research suggests that software development can actually be jointly-developed by rival firms. For instance, it is known that the mobile-device makers Apple and Samsung kept collaborating in open source projects while running expensive patent wars in the court. Taking a case study approach, we explore how rival firms collaborate in the open source arena by employing a multi-method approach that combines qualitative analysis of archival data (QA) withmining software repositories (MSR) and Social Network Analysis (SNA). While exploring collaborative processes within the OpenStack ecosystem, our research contributes to Software Engineering research by exploring the role of groups, sub-communities and business models within a high-networked open source ecosystem. Surprising results point out that competition for the same revenue model (i.e., operating conflicting business models) does not necessary affect collaboration within the ecosystem. Moreover, while detecting the different sub-communities of the OpenStack community, we found out that the expected social tendency of developers to work with developers from same firm (i.e., homophony) did not hold within the OpenStack ecosystem. Furthermore, while addressing a novel, complex and unexplored open source case, this research also contributes to the management literature in coopetition strategy and high-tech entrepreneurship with a rich description on how heterogeneous actors within a high-networked ecosystem (involving individuals, startups, established firms and public organizations) joint-develop a complex infrastructure for big-data in the open source arena.","2015-07-24","2025-05-05 17:04:36","2025-05-05 17:04:36","","NA","","NA","6","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although it is becoming the remote sensing platform of choice for planning and natural resource agencies that require three-dimensional information, the enormous data that are generated and the lack of available software analysis packages make LiDAR still unavailable to a typical user of spatial data. LiDARHub is a free and open source platform for web-based management, visualization and analysis of LiDAR data that enables development of online tools for LiDAR data processing in a web browser. The framework provides a foundation to develop online tools for LiDAR data processing and tools can be shared. The framework is also flexible so that the developed tools can be easily ported to High Performance Computing (HPC) environments that speed up the computationally extensive LiDAR data processing. Two example LiDARHub tools are presented as case studies to demonstrate potential software development scenarios.

We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers.

Analyzing these deformations allows a better understanding of the causes and mechanisms of the events. By using sub-pixel correlation on before- and after-event ortho-images obtained from high resolution satellite images it is possible to compute the displacement field with high planimetric resolution. In this paper, we focus on measuring the ground displacements due to seismotectonic events. The three sub-pixel correlators used are: COSI-Corr - developed by Caltech, a free, closed-source correlator, dependent on commercial software (ENVI) and widely used by the geoscience community for measuring ground displacement; Medicis - developed by CNES, also a closed-source correlator capable of measuring this type of deformation; and MicMac - developed by IGN, the free open-source correlator we study and tune for measuring fine ground displacements.

Through professional and occupational competences, individuals are able to deal with the requirements of the phenomenon of globalization. Therefore, many countries have been involved in the creation of quality assurance of educational systems in order to design more flexible curricula, more open to knowledge society. They meet the vast training needs, provide a variety of educational strategies and drive academic mobility and collaborative inter or multidisciplinary projects. In this respect, educational institutions are called to promote methodologies focused on the study of curriculum to diagnose and base the formulation of improvement plans for quality assurance. This project formulated a methodology to examine and determine the level of curricular flexibility. It was based on a prototype of an information system developed with free software that supported management indicators and represented different manifestations of flexibility. On the other hand, the Viable System Model provided the theoretical foundation to specify the study and the organizational diagnosis and to identify the information needs among defined sub-systems, including environment. The prototype of the information system was designed so that academic programs within a higher education institution have the capacity to structure several studies of curriculum flexibility over time in order to establish the necessary comparatives and to be a knowledge-based supply for future curriculum reforms and a basis for quality assurance processes.

Free software communities can be considered communities of practice, since they aggregate people interested in donating and collecting, that is, sharing knowledge about free software. According to the literature, the donation and collection of knowledge are motivated by different factors and these motivations may vary depending on the context. Free software communities may include members from different countries and backgrounds, which can make keeping such communities active and vigorous a challenge. This study aims to identify the motivations for knowledge sharing behaviour that are susceptible to leadership actions in free software communities. The research was carried out in three phases. First, a qualitative study involving twenty semi-structured interviews was conducted among members of a free software community, who suggested sixteen motivations for knowledge sharing behaviour. These motivations were then organized into three groups, each with a specific focus: three motivations only influence knowledge collection and focus on the knowledge itself; nine motivations only influence knowledge donation and focus on the individual; and four motivations influence both knowledge collection and knowledge donation, and focus on the relationships among individuals. After that, based on the groups of motivation identified in the previous phase, five leaders from different communities of practice were interviewed with the aim of identifying the main motivations that would be susceptible to their actions, which were knowledge quality, ease of access to knowledge, recognition, community support for knowledge sharing, learning and professional reasons. Finally, these six main motivations indicated by the leaders were tested in a quantitative phase involving 260 members of different free software communities. The results show that learning and ease of access to knowledge influence knowledge collection; recognition, community support for knowledge sharing and knowledge collection influence knowledge donation; and professional reasons influence both knowledge collection and knowledge donation in the context of free software communities.","2015","2025-05-05 17:04:37","2025-05-05 17:04:37","","86-94","","NA","NA","","","","Proceedings of the European Conference on Knowledge Management","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-910810-47-7 Place: NA Publisher: NA","","","","NA","","Massaro, M.; Garlatti, A.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Likewise, the economic theory of the firm, building on Ronald Coase's (1937) seminal analysis, has become an increasingly important field in economics and management. Despite this resurgence, there is still little connection between the entrepreneurship literature and the literature on the firm, both in academia and in management practice. This book fills this gap by proposing and developing an entrepreneurial theory of the firm that focuses on the connections between entrepreneurship and management.

Traditional requirements engineering (RE) techniques addressing stakeholders’ social interaction are mainly part of a centralized process intertwined with a specific phase of software development. However, in open-source software (OSS) development, stakeholders’ social interactions are often decentralized, iterative, and dynamic. Little is known about new requirements identification in OSS and the stakeholders’ organizational arrangements supporting such an activity. In this article, we investigate the theory of structural hole from the context of contributing new requirements in OSS projects. Structural hole theory suggests that stakeholders positioned in the structural holes in their social network are able to produce new ideas. In this study, we find that structural hole positions emerge in stakeholders’ social network and these positions are positively related to contributing a higher number of new requirements. We find that along with structural hole positions, stakeholders’ role is also an important part in identifying new requirements. We further observe that structural hole positions evolve over time, thereby identifying requirements to realize enriched features. Our work advances the fundamental understanding of the RE process in a decentralized environment and opens avenues for improved techniques supporting this process.","2015-09","2025-05-05 17:04:39","2025-05-05 17:04:39","","NA","","3","6","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","social capital; brokerage; open-source requirements engineering; Requirements identification; social information foraging theory; stakeholders’ social network; structural hole","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As nations increasingly rely on knowledge assets to grow, the adoption of OSS will have profound economic consequences. This paper identifies the mechanisms inherent to OSS production that help fuel innovation in knowledge-based economies. As a collaborative and open production model, OSS is conceptualized as a prototype of open innovation. Drawing on US employment projections for 2008-2018, the authors' analysis predicts OSS will have a positive impact on employment growth in well-paid salary jobs across multiple sectors of the US economy. OSS-related software development jobs are widely diffuse throughout the economy, help build a skilled labour force and offer wages significantly above the national average. OSS is thus believed to be a strong contributor to growth in high-value employment in the US. The authors also posit that, as industries are exposed to the benefits of OSS as a result of the broad diffusion of OSS-related jobs, open innovation processes outside software development may be adopted through a process of learning and imitation.","2015","2025-05-05 17:04:39","2025-05-05 17:04:39","","528-560","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-4666-7231-4; 978-1-4666-7230-7 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standard communication protocols facilitate interconnectivity between software components and assure interoperability between different stakeholders of these components. For electric grids, standards introduce an open Smart Grid for liberalized service-oriented electricity markets by smoothing the way for business interactions and trades. Many organizations such as IEC and IEEE are introducing their standard communication protocols for future smart power grids and their associated smart meters. These standards include but not limited to, IEEE 802, IEEE 1815, IEEE 1901, IEC 62056, IEC 60870-5-104, IEC 61850, etc. For smart buildings, smart homes and some wireless sensor networks (WSN), ZigBee is widely used. For smart roads, Internet of Things (IoT) is used in some cases including its messaging protocol Constraint Application Protocol (CoAP) together with WSN. In this paper, open source software (OSS) implementation of such standard protocols is discussed, including obstacles and advantages of a such implementation. Moreover, wireless telecommunication infrastructures including Wi-Fi, ZigBee, and Bluetooth are investigated for the right choice of Smart City applications' infrastructure, since the employment of a standard should be compatible with the field of application, timing requirements and data transmission rate.","2015","2025-05-05 17:04:40","2025-05-05 17:04:40","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Hochschule Bonn Rhein Sieg; IEEE Jordan Sect; GJU; Brunel Univ London;\n UCLM; NDU; Talal Abu Ghazaleh Informat Technol Int; Tarent ISBN: 978-1-4673-7465-1 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Increasing the amount of students that pursue STEM majors is important because the projected job growth in the STEM field compared to non-STEM jobs is 33%. OSALT provides cost-effective alternatives to commercial products such as Microsoft Office Suite and Adobe Photoshop. Second, creating Virtual Machines (VMs) is another avenue to teach complex concepts in computer science, engineering, and Information Technology (IT). Third, cloud computing is an inexpensive way for clients to access information from multiple locations and devices. Fourth, universities can use the Operating System (OS) Linux and its various distributions as replacements for commercial operating systems like Windows in order to reduce IT costs.

Despite recent advances in imaging techniques, the application of unbiased computational image analysis methods for morphodynamic quantification is rare. For example, manual analysis using kymographs is still commonplace, often caused by lack of access to user-friendly, automated tools. We now describe software designed for the automated quantification of cell migration and morphodynamics. Implemented as a plug-in for the open-source platform, ImageJ, ADAPT is capable of rapid, automated analysis of migration and membrane protrusions, together with associated fluorescently labeled proteins, across multiple cells. We demonstrate the ability of the software by quantifying variations in cell population migration rates on different extracellular matrices. We also show that ADAPT can detect and morphologically profile filopodia. Finally, we have used ADAPT to compile an unbiased description of a “typical” bleb formed at the plasma membrane and quantify the effect of Arp2/3 complex inhibition on bleb retraction.","2015-04-13","2025-05-05 17:04:40","2025-05-05 17:04:40","","163-180","","1","209","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

No studies have been found which have undertaken research on the impact of user experience and training on OSS. The study reported here sought to identify factors that predict acceptance of technologies based on OSS after training in these solutions. A research model based on the Technology Acceptance Model (Davis, 1989) was developed. Furthermore, the possible moderating effects of users' gender, age and level of education were analyzed. It was found that external determinants such as user training, user fit, technological complexity and trainers' support were important indicators in the success of adopting these solutions.

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.","2015-03","2025-05-05 17:04:40","2025-05-05 17:04:40","","224-237","","1","26","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS","","","","open source software; firm attributes; firm sponsorship; voluntary contributions; intrinsic\n motivation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).","2015","2025-05-05 17:04:41","2025-05-05 17:04:41","","119-139","","1","39","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: Floor 5, Northspring 21-23 Wellington Street, Leeds, W YORKSHIRE,\n ENGLAND Publisher: EMERALD GROUP PUBLISHING LTD","","","","Open source software; Motivations; Open content; Social Q&A","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The experimental results show that obtaining Calotropis gigantea seed fibers by microwave heating the pods is feasible. Compared to natural air drying and hot air drying, the microwave drying (MW can significantly improve the drying efficiency and reduce the drying time by more than 5 times. The microwave power has considerable influences on the drying rate. However, the fiber strength and break elongation are reduced with the increase of microwave power due to fiber structural change caused by the high temperature inside the pod. Compared with intermittent radiation, the moisture loss rate of the pods is greater in continuous radiation mode, but the pod internal temperature is higher, which is harmful to the quality of the fibers. Varying power radiation, which uses lower power first, then higher, could shorten drying time without impeding the pods' abdominal suture broadening.","2015","2025-05-05 17:04:42","2025-05-05 17:04:42","","251-258","","5","66","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The review consists of two parts: First, we developed a criteria catalogue and rated the tools regarding structural requirements, functionality (flexibility, segmentation and image processing filters) and usability (documentation, data management, usability and visualization). Second, we performed an image processing case study with four representative fluorescence micrograph segmentation tasks with figure-ground and cell separation. The tools display a wide range of functionality and usability. In the image processing case study, we were able to perform figure-ground separation in all micrographs using mainly thresholding. Cell separation was not possible with most of the tools, because cell separation methods are provided only by a subset of the tools and are difficult to parametrize and to use. Most important is that the usability matches the functionality of a tool. To be usable, specialized tools with less functionality need to fulfill less usability criteria, whereas multipurpose tools need a well-structured menu and intuitive graphical user interface.","2015-01","2025-05-05 17:04:42","2025-05-05 17:04:42","","39-53","","1","257","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is important for Open Source Software (OSS) projects, which receive contributions from many one-time contributors. Focusing on OSS, our study qualitatively analyzed social barriers that hindered newcomers' first contributions. We defined a conceptual model composed of 58 barriers including 13 social barriers. The barriers were identified from a qualitative data analysis considering different sources: a systematic literature review; open question responses gathered from OSS projects' contributors; students contributing to OSS projects; and semi-structured interviews with 36 developers from 14 different projects.

Free open source software projects generally have one mailing list for developers and another one for users. This large number of mailing lists changes constantly and shows a great variety with respect to membership and topics covered. This makes them very difficult to monitor. One way of overcoming this Big Data Challenge is to identify some easily computable global indicators that can be used for instance to detect important events. We illustrate this approach here by making a social network analysis and comparison of developers' and users' mailing lists of four free open source software projects: CentOS, GnuPG, Mailman and Samba. We show that these mailing lists have some common characteristics: the number of messages, the time durations and the interlink times can be fitted using power and lognormal laws with suitable scales and parameters, for the interlink time, the analysis is done using the temporal delta density inspired by the delta density introduced by Viard and Latapy. This similarity between the characteristics of mailing lists also applies to the structure of dominant groups. For the time evolution of the number of messages, GnuPG exhibits a particular behavior. The interpretation of the different parameters gives very interesting insights into the membership and the type of topics covered by the mailing lists. The analysis carried out here and similar studies cited in this paper can therefore be considered as a first step towards the designing of building blocks for monitoring mailing lists.","2015","2025-05-05 17:04:45","2025-05-05 17:04:45","","728–732","","NA","NA","","","","BIGDATACONGRESS '15","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; Serv Comp; Serv Soc; Comp Cloud; Serv Comp; BIG\n Data; Hp; IBM; ERICSSON; SAP; IBM Res; HUAWEI; OMG Object Management\n Grp; IEEE Cloud Comp; Business Proc Integrat & Management; IT Profess;\n Intl Journal Web Serv Res; Comp Now Access Discover Engage; IEEE\n Transact Serv Comp ISBN: 9781467372787 Place: USA Publisher: IEEE Computer Society","","","","Big data; mailing list; characteristic time; complementary cumulative distribution; delta density; discussion thread; dominant member; free open source software project; lognormal law; outstanding event detection; power law","","Barbara, C.; Khan, L.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The introduction of Open Source Software technologies in the Public Administration plays a key role in the spread of Open Source Software. The state of the art in the adoption of Open Source Software solutions in the Public Administration is not very well known even in areas like Lombardy, which is Italy's largest and most developed region. Goal. The goal of the investigation documented in this paper is to obtain a clear picture about the introduction of Open Source Software technologies in the Public Administration, the obstacles to their adoption, and the willingness of stakeholders to proceed with their introduction. Method. We carried out a qualitative and quantitative survey that was submitted to a representative part of the Public Administrations in Lombardy. Results. The analysis of the qualitative and quantitative information shows that several Public Administrations are already using Open Source Software technologies, though not in all application areas. The savings are one frequently cited incentive to the adoption of Open Source Software. However, one obstacle is the fact that a comprehensive law on software in the Public Administration has not yet been approved. Conclusions. Our analysis provides results that indicate a common understanding of incentives, obstacles, and opportunities for Open Source Software technologies in Public Administrations.","2015","2025-05-05 17:04:48","2025-05-05 17:04:48","","114-123","","NA","451","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13; Google ISBN: 978-3-319-17837-0; 978-3-319-17836-3 Place: NA Publisher: NA","","","","NA","","Damiani, E.; Frati, F.; Riehle, D.; Wasserman, A.

However, institutional recognition has not been fully awarded mainly due to the absence of a comprehensive reporting framework. The objective of our research is to identify indicators in order to measure open source projects performance. Motivation that led us to carry out this analysis was the fact that, despite the many benefits attributed to open sourcing, no information about it was disclosed on annual reports. We are based on previous literature about creating institutions to governing the commons. One of the key goals is institutional reporting to members of the community, so we believe that a reporting model based on social responsibility framework is clearly suitable for this purpose. Social responsibility and sustainability are about enabling organizations to incorporate creation of social, environmental and economic value into core strategy and operations; their reporting is key to create value for organizations, their stakeholders and society as a whole. To reach our goal, we asked a panel of open source experts their opinion about the key success factors and other relevant variables for the purpose of recommending a methodology to calculate specific indicators to be disclosed on social responsibility reports.","2015","2025-05-05 17:04:48","2025-05-05 17:04:48","","369-397","","1","9","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: Unit 3N, 6 Osborn Street, LONDON, E1 6TD, ENGLAND Publisher: UBIQUITY PRESS LTD","","","","peer production; open source software; sustainability; Free software; reporting; social\n responsibility","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the developers of a number of open-source software (OSS) projects highlight the potential of OSS to advance radar-related research. We argue that the community-based development of OSS holds the potential to reduce duplication of efforts and to create transparency in implemented algorithms while improving the quality and scope of the software. We also conclude that there is sufficiently mature technology to support collaboration across different software projects. This could allow for consolidation toward a set of interoperable software platforms, each designed to accommodate very specific user requirements.","2015-01","2025-05-05 17:04:49","2025-05-05 17:04:49","","117-128","","1","96","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study. We reveal that Landsat 8 data combined with texture analysis can accurately detect these artificial landmarks across the heterogeneous environment of OROAFR; 75.68% of artificial water points within the site were successfully identified and false positive detection rate was minimal at 7.69%. The methodological framework developed for this work, based on the treatment of freely available satellite data using open source software, adds to other works attempting to help monitor threats to biodiversity in desert ecosystems, enabling up-to-date information on the level of anthropogenic activities in these habitats to be easily and regularly collected.","2015-10","2025-05-05 17:04:52","2025-05-05 17:04:52","","61-72","","1","1","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN, NJ 07030 USA Publisher: WILEY","","","","open source; Anthropogenic activity; deserts; land use change; satellite data; remote\n sensing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We then compare the rate at which software developers decided whether to accept or reject the new pastebin tools. We find that the overall rate of pastebin adoption follows the S-curve predicted by classic DoI theory. We then compare the individual pastebin services and their rates of adoption, as well as the reaction of different communities to the new tools and the various rationales for accepting or rejecting them.","2015","2025-05-05 17:04:52","2025-05-05 17:04:52","","45-57","","NA","451","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 2 13; Google ISBN: 978-3-319-17837-0; 978-3-319-17836-3 Place: NA Publisher: NA","","","","NA","","Damiani, E.; Frati, F.; Riehle, D.; Wasserman, A.

Despite the immense success of several mainstream OSS projects such as Mozilla, Linux, and Apache, a vast majority of such projects fail to sustain their development due to high levels of developer turnover. While existing research in the area has offered a rich foundation, we know little about how developers' perceptions of fit with the project environment may be moderated by the sense of ownership they have toward the project and how it may impact their turnover intentions. Using survey data from 574 GitHub developers, we tested a model to examine the impact of Person-Organization fit and psychological ownership on developers' turnover intentions. Our results suggest that two relevant dimensions of fit, namely, value and demands-abilities fit, negatively impact turnover intentions and that their sense of ownership moderates these effects.","2015","2025-05-05 17:04:53","2025-05-05 17:04:53","","NA","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-0-9966831-0-4 Place: P.O.

However, the form that data sharing took in genomics was a result of specific technological practices. Biologists developed and adopted technologies of the nascent World Wide Web and Free and Open Source Software (FOSS) communities for sharing biological information. These technologies supported decentralized, collaborative, and nonproprietary modes of production in biology. Such technologies were appealing not merely because they were expedient for genomic work but because they also offered a way of promoting a particular form of genomic practice. As the genome sequencing centers scaled up their sharing efforts, a small group of computer-savvy biologists used these tools to promote the interests of the public genome sequencing effort. The agreements at Bermuda should be understood as part of this attempt to foster a particular form of genomic work.","2015","2025-05-05 17:04:54","2025-05-05 17:04:54","","465-503","","4","50","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Online discussions are almost synchronous written conversations that can be analyzed applying computational linguistic techniques that build on the speech act theory. Our approach builds on this observation. We propose to analyze OSS mailing-list discussions in terms of the linguistic and non-linguistic acts expressed by the participants, and provide a tool-supported speech-act analysis method.

This large amount of data hampers people to make sense of implicit links between software projects, e.g., dependencies, patterns, licenses. This context raises the question of what techniques and mechanisms can be used to help users and developers to link related pieces of information across software projects. In this paper, we propose a framework for a marketplace enhanced using linked open data (LOD) technology for linking software artifacts within projects as well as across software projects. The marketplace provides the infrastructure for collecting and aggregating software engineering data as well as developing services for mining, statistics, analytics and visualization of software data. Based on cross-linking software artifacts and projects, the marketplace enables developers and users to understand the individual value of components and their relationship to bigger software systems. Improved understanding creates new business opportunities for software companies: users will be able to analyze and compare projects, developers can increase the visibility of their products, and hosts may offer plugins and services over the data to paying customers.","2015","2025-05-05 17:04:58","2025-05-05 17:04:58","","3651-3660","","NA","NA","","","","Proceedings of the Annual Hawaii International Conference on System\n Sciences","","","","","","NA","","","","","","","Backup Publisher: IEEE Comp Soc; Univ Hawaii, Shidler Coll Business; Univ Hawaii, Dept EE;\n Univ Hawaii, Informat Sci Program; ONR; AFOSR; Natl Sci Fdn; IEEE Syst\n Sci & Cybernet Soc; ACM; SIAM; IEEE Hawaii Sect; IEEE Control Syst Soc;\n IEEE Grp Informat Theory; IEEE Grp Automat Control; ARO; Reg Med Program\n Hawaii; Univ Hawaii, Coll Business Adm; Nasdaq ISBN: 978-1-4799-7367-5 Place: USA Publisher: IEEE Computer Society","","","","open source software; linked data; semantic web","","Bui, T.

Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. However, there is a lack of support for assessing the impact of the OSS adoption over the business of the adopter organizations. Based on the goal-oriented characterization of some OSS adoption strategies, in this paper, we propose a preliminary approach to assess the business impact of the OSS adoption strategies over the adopter organizations. The proposal is based on the Business Model Canvas and graph theory notions to support the elicitation and assessment of the impact of each goal over the adopter organization.

To further investigate this specific barrier, we conducted a qualitative analysis with data obtained from semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members.

We found that newcomers are not confident enough to choose their initial task and they need information about the tasks or direction from the community to support choosing a task more suitable for them.

We emphasize social network analysis as a method especially suitable for management of open source development projects, because it focuses on relations among individuals rather than attributes of individual cases. We show how open source development can be represented as a collaboration network graph and how the network can be characterized by various network structure metrics. We present four metrics as a starting point size, centralization, density and clusterness; that are most useful in revealing collaborative relationships in OSS development process.

However, such tasks require extensive project experience of long term contributors (LTCs). Aim: We measure, understand, and predict how the newcomers' involvement and environment in the issue tracking system (ITS) affect their odds of becoming an LTC. Method: ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. We also reproduced the results on new data provided by Mozilla. Results: We constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants. Newcomers who are able to get at least one issue reported in the first month to be fixed, doubled their odds of becoming an LTC. The macro-climate with high project popularity and the micro-climate with low attention from peers reduced the odds. The precision of LTC prediction was 38 times higher than for a random predictor. We were able to reproduce the results with new Mozilla data without losing the significance or predictive power of the previously published model. We encountered unexpected changes in some attributes and suggest ways to make analysis of ITS data more reproducible.

Our laboratory exploits PCR techniques and Next Generation Sequencing (NGS) methods to perform high-throughput integration site monitoring in different clinical trials and scientific projects. Because of the huge amount of samples that we process every year, which result in hundreds of millions of sequencing reads, we need to standardize data management and tracking systems, building up a scalable and flexible structure with web-based interfaces, which are usually called Laboratory Information Management System (LIMS). Methods: We started collecting end-users' requirements, composed of desired functionalities of the system and Graphical User Interfaces (GUI), and then we evaluated available tools that could address our requirements, spanning from pure LIMS to Content Management Systems (CMS) up to enterprise information systems. Our analysis identified ADempiere ERP, an open source Enterprise Resource Planning written in Java J2EE, as the best software that also natively implements some highly desirable technological advances, such as the high usability and modularity that grants high use-case flexibility and software scalability for custom solutions. Results: We extended and customized ADempiere ERP to fulfil LIMS requirements and we developed adLIMS. It has been validated by our end-users verifying functionalities and GUIs through test cases for PCRs samples and pre-sequencing data and it is currently in use in our laboratories. adLIMS implements authorization and authentication policies, allowing multiple users management and roles definition that enables specific permissions, operations and data views to each user. For example, adLIMS allows creating sample sheets from stored data using available exporting operations. This simplicity and process standardization may avoid manual errors and information backtracking, features that are not granted using track recording on files or spreadsheets. Conclusions: adLIMS aims to combine sample tracking and data reporting features with higher accessibility and usability of GUIs, thus allowing time to be saved on doing repetitive laboratory tasks, and reducing errors with respect to manual data collection methods. Moreover, adLIMS implements automated data entry, exploiting sample data multiplexing and parallel/transactional processing. adLIMS is natively extensible to cope with laboratory automation through platform-dependent API interfaces, and could be extended to genomic facilities due to the ERP functionalities.","2015-06-01","2025-05-05 17:05:02","2025-05-05 17:05:02","","NA","","9","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Bioinformat Italian Soc ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Additionally, they are often difficult or at very high risk for biopsy, further hindering the clinical management process. To overcome this, novel advanced imaging methods are increasingly being adapted clinically to identify useful noninvasive biomarkers capable of disease stage characterization and treatment response prediction. One promising technique is called functional diffusion mapping (fDM), which uses diffusion-weighted imaging (DWI) to generate parametric maps between two imaging time points in order to identify significant voxel-wise changes in water diffusion within the tumor tissue. Here we introduce serial functional diffusion mapping (sfDM), an extension of existing fDM methods, to analyze the entire tumor diffusion profile along the temporal course of the disease. sfDM provides the tools necessary to analyze a tumor data set in the context of spatiotemporal parametric mapping: the image registration pipeline, biomarker extraction, and visualization tools. We present the general workflow of the pipeline, along with a typical use case for the software. sfDM is written in Python and is freely available as an open-source package under the Berkley Software Distribution (BSD) license to promote transparency and reproducibility.","2015","2025-05-05 17:05:03","2025-05-05 17:05:03","","1-9","","2","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The software implements a model to explain the allelic peak height on a continuous scale in order to carry out weight-of-evidence calculations for profiles which could be from a mixture of contributors. Through a properly parameterized model we are able to do inference on mixture proportions, the peak height properties, stutter proportion and degradation. In addition, EuroForMix includes models for allele drop-out, allele drop-in and sub-population structure. EuroForMix supports two inference approaches for likelihood ratio calculations. The first approach uses maximum likelihood estimation of the unknown parameters. The second approach is Bayesian based which requires prior distributions to be specified for the parameters involved. The user may specify any number of known and unknown contributors in the model, however we find that there is a practical computing time limit which restricts the model to a maximum of four unknown contributors. EuroForMix is the first freely open source, continuous model (accommodating peak height, stutter, drop-in, drop-out, population substructure and degradation), to be reported in the literature. It therefore serves an important purpose to act as an unrestricted platform to compare different solutions that are available. The implementation of the continuous model used in the software showed close to identical results to the R-package DNAmixtures, which requires a HUGIN Expert license to be used. An additional feature in EuroForMix is the ability for the user to adapt the Bayesian inference framework by incorporating their own prior information. (C) 2015 Elsevier Ireland Ltd.

To achieve this goal, we developed a Bayesian Belief Network (BBN) involving several maintainability predictors and three managerial indices for maintenance (i.e., duration, production, and productivity) on 20 open source software projects.

PaaSage is an open source integrated platform to support both design and deployment of cloud applications. The PaaSage consortium decided to publish the source code as open source. It needed a process for the open source license selection. Open source licensing scheme born before the development of cloud computing and evolved with the creation of new open source licenses suitable for SaaS applications. The license is a part of project governance and strongly influences the life of the project. In the context of the PaaSage European project, the issue of the open source license selection for cloud computing software has been addressed.

Lately, metrics related to change activity have also been included to understand OSS evolution. Change activity as recorded in Source Code Management (SCM) systems is used in a few cases. Most of the work deals with finding change size, and change effort distributions. A few studies do change profile analysis as OSS systems evolve. But that is restricted to a few of the change categories, e.g., adaptive v/s non-adaptive changes, corrective v/s non-corrective changes. This research study explores change profiles of 106 OSS systems by extracting change type information from their SCM repositories and then categorizing these changes automatically into five different categories - corrective, adaptive, perfective, preventive, and enhancement related.

Currently coupled computations solve the same governing equations using different coupling methods, which can be sorted into two categories: loose coupling and tight coupling. This paper proposes and verifies a third coupling approach called “the Integrated Tight Coupling (ITC) method”. The mathematical equations in the nuclear fuel are rearranged to be integrated via a novel concept of the energy-group function. In addition, the data from the neutron cross section library can be used directly. The ITC method is implemented using two open-source codes: the DRAGON code and OpenFOAM. Additionally, a coupled computation using these two codes is new and has not been done. The ITC method is verified using a 1.5-D (1-D neutronics and 2-D thermal-hydraulics) symmetric unit cell example. The mesh of the tightly integrated computation is 25% coarser than the loosely coupled one. Starting from a similar initial guess, the number of iterations for the ITC method is 24% fewer than that for the loosely coupled computation to reach the same accuracy. In addition, the ITC method is tested with different initial guesses. For all cases tested, the scheme converged to the same solution. With further improvement and additional testing, the ITC method has the potential to be incorporated with other neutronics and thermal-hydraulics codes. (C) 2015 Elsevier Ltd.

The second section generally explains the modelling and simulation of a UAV. In the main section, more than 50 free programs for the design, analysis, modelling, and simulation of a UAV are described.

There are many open-source architecture frameworks for UAS that claim the autonomous operation of UAS, but they still have two main open issues: (1) level of autonomy, being in most of the cases limited and (2) versatility, being most of them designed specifically for some applications or aerial platforms. As a response to these needs and issues, this paper presents Aerostack, a system architecture and open-source multi-purpose software framework for autonomous multi-UAS operation. To provide higher degrees of autonomy, Aerostack's system architecture integrates state of the art concepts of intelligent, cognitive and social robotics, based on five layers: reactive, executive, deliberative, reflective, and social. To be a highly versatile practical solution, Aerostack's open-source software framework includes the main components to execute the architecture for fully autonomous missions of swarms of UAS; a collection of ready-to-use and flight proven modular components that can be reused by the users and developers; and compatibility with five well known aerial platforms, as well as a high number of sensors. Aerostack has been validated during three years by its successful use on many research projects, international competitions and exhibitions. To corroborate this fact, this paper also presents Aerostack carrying out a fictional fully autonomous indoors search and rescue mission.","2016","2025-05-05 17:05:11","2025-05-05 17:05:11","","332-341","","NA","NA","","","","International Conference on Unmanned Aircraft Systems","","","","","","English","","","","","","","Backup Publisher: IEEE; IEEE Robot & Automat Soc; IEEE CSS; MCA ISBN: 978-1-4673-9333-1 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study is conducted on 13 open source systems comprising over 14 MLOC. Each for-loop is statically analyzed to determine if it can be parallelized or not. A for-loop that can be parallelized is termed a free-loop. Free-loops can be easily parallelized using tools such as OpenMP. For the loops that cannot be parallelized, the various inhibitors to parallelization are determined and tabulated. The data shows that the most prevalent inhibitor by far, is functions called within for-loops that have side effects. This single inhibitor poses the greatest challenge in adapting and re-engineering systems to better utilize modern multi-core architectures. This fact is somewhat contradictory to the literature, which is primarily focused on the removal of data dependencies within loops. Results of this paper also show that function calls via function pointers and virtual methods have very little impact on the for-loop parallelization process. Historical data over a 10-year period of inhibitor counts for the set of systems studied is also presented. It shows that there is little change in the potential for parallelization of loops over time.","2016-06","2025-05-05 17:05:14","2025-05-05 17:05:14","","1272-1301","","3","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, since reused components are (by definition) generic, they need to be customized and integrated into a specific system before they can be useful. Since this integration is system-specific, the integration effort is non-negligible and increases maintenance costs, especially if more than one component needs to be integrated. This paper performs an empirical study of multi-component integration in the context of three successful open source distributions (Debian, Ubuntu and FreeBSD). Such distributions integrate thousands of open source components with an operating system kernel to deliver a coherent software product to millions of users worldwide. We empirically identified seven major integration activities performed by the maintainers of these distributions, documented how these activities are being performed by the maintainers, then evaluated and refined the identified activities with input from six maintainers of the three studied distributions. The documented activities provide a common vocabulary for component integration in open source distributions and outline a roadmap for future research on software integration.","2016-06","2025-05-05 17:05:14","2025-05-05 17:05:14","","960-1001","","3","21","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER","","","","Debian; Software reuse; Open source distributions; Software integration; FreeBSD; \n Ubuntu","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, even after 20 years of intense research in this field, perfusion imaging still remains a research tool without a broad clinical usage. One problem is the lack of standardization in technical aspects which have to be considered for successful quantitative evaluation; the second problem is a lack of tools that allow a direct integration into the diagnostic workflow in radiology. Results: Five compartment models, namely, a one compartment model (1CP), a two compartment exchange (2CXM), a two compartment uptake model (2CUM), a two compartment filtration model (2FM) and eventually the extended Toft's model (ETM) were implemented as plugin for the DICOM workstation OsiriX. Moreover, the plugin has a clean graphical user interface and provides means for quality management during the perfusion data analysis. Based on reference test data, the implementation was validated against a reference implementation. No differences were found in the calculated parameters. Conclusion: We developed open source software to analyse DCE-MRI perfusion data. The software is designed as plugin for the DICOM Workstation OsiriX. It features a clean GUI and provides a simple workflow for data analysis while it could also be seen as a toolbox providing an implementation of several recent compartment models to be applied in research tasks. Integration into the infrastructure of a radiology department is given via OsiriX. Results can be saved automatically and reports generated automatically during data analysis ensure certain quality control.","2016-01-14","2025-05-05 17:05:16","2025-05-05 17:05:16","","NA","","NA","16","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC","","","","Open source software; Data analysis; Compartment models; Dce-mri; \n Workflow","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

RE is characterized as a socio-technical distributed cognitive (DCog) activity where multiple actors deploy artifacts to `compute' requirements. To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community.

Here we introduce AxonSeg, which allows to perform automatic axon and myelin segmentation on histology images, and to extract relevant morphometric information, such as axon diameter distribution, axon density and the myelin g-ratio. AxonSeg includes a simple and intuitive MATLABbased graphical user interface (GUI) and can easily be adapted to a variety of imaging modalities. The main steps of AxonSeg consist of: (i) image pre-processing; (ii) pre-segmentation of axons over a cropped image and discriminant analysis (DA) to select the best parameters based on axon shape and intensity information; (iii) automatic axon and myelin segmentation over the full image; and (iv) atlas-based statistics to extract morphometric information.

Controlling the software maintainability and understandability of any open source software (OSS) system is extremely challenging because it is written and constantly modified by the developers located all over the world. The current study analyzes the effectiveness of machine learning (ML) techniques for the maintainability prediction of OSS systems. In this work large-scale empirical comparisons of thirteen classifiers over seven open source datasets were conducted followed by extensive statistical tests and post hoc analysis to establish the confidence on the performance of one ML technique over another. The results show two important findings: firstly, we observed that overall good prediction accuracy is achieved by almost all ML techniques; secondly the prediction models using genetically adaptive learning ML technique and group method of data handling (GMDH) technique perform better than the other ML techniques in the context of OSS systems. The outcome of this investigation would be helpful for developers in order to predict maintenance behavior of the software at the earlier stages of software development lifecycle (SDLC).

The use of OSS does not harm security; on the contrary, it enhances it. Even with some drawbacks, OSS is highly reliable and maintained by a huge software community, thus decreasing implementation costs and increasing reliability. Moreover, it allows military software engineers to move away from proprietary applications and single-vendor contracts. Furthermore, it decreases the cost of long-term development and lifecycle management, besides avoiding vendor's lock in. Nevertheless, deploying OSS deserves an appropriate organization of its life cycle and maintenance, which has a relevant impact on the project's budget that cannot be overseen. In this paper, we will describe some of the major trends in OSS in Defense environments. The community for OSS has a pivotal role, since it is the core development unit. With Agile and the newest DevOps methodologies, government officials could leverage OSS capabilities, decreasing the Design (or Technical) Debt.

Here we describe BluePyOpt, a Python package targeted at the broad neuroscience community to simplify this task. BluePyOpt is an extensible framework for data-driven model parameter optimisation that wraps and standardises several existing open-source tools. It simplifies the task of creating and sharing these optimisations, and the associated techniques and knowledge. This is achieved by abstracting the optimisation and evaluation tasks into various reusable and flexible discrete elements according to established best-practices. Further, BluePyOpt provides methods for setting up both small- and large-scale optimisations on a variety of platforms, ranging from laptops to Linux clusters and cloud-based compute infrastructures. The versatility of the BluePyOpt framework is demonstrated by working through three representative neuroscience specific use cases","2016-06-07","2025-05-05 17:05:21","2025-05-05 17:05:21","","NA","","NA","10","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In a society based on a federal structure and the principle of subsidiarity, it is almost natural to demand a vivid community with active citizens. Today, with the advent of social media and the new channels of communication, the question is how to leverage the benefits of this concept for local issues. More precise: How can the competence of the citizens be activated to make conditions of living in the neighbourhoods more attractive? In this paper, we discuss technical requirements for an open government. The SAGA standard of the Federal German Government strongly supports the notion of open-source software. With OpenSAGA, we introduce a new, performant and SAGA-compliant framework for the implementation of web applications for e-Government. Consequently, OpenSAGA is the platform for an OpenGovernment Suite, an extended prototype for affordable and interoperable open government solutions.","2016-08","2025-05-05 17:05:23","2025-05-05 17:05:23","","361-370","","3, SI","31","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To address this issues software's need a careful profiling in its development process to make the software efficient and less resource hungry. In this paper we compared some of the profiling tools available as Free and Open Source Software (FOSS) which are used under Linux environment. These software tools uses different strategies and have different accuracies in finding a system and software programs behavior and its resource requirements. Their performance and resource overheads such as memory, CPU, disk consumption were compared and results are summarized for making the tools selection easier to researchers and developers alike.

However, “unresolved interdependencies” remain that cannot be addressed by such arm's length mechanisms. These interdependencies reflect, for example, unidentified or emerging knowledge-based dependencies between the community members or unaccounted relationships between ongoing community tasks. At the same time, online communities cannot resort to hierarchical coordination mechanisms such as incentives or command structures to address such interdependencies. So, how do they manage such interdependencies? To address this question, we conduct an exploratory, theory-generating case study involving qualitative and computational analyses of development activities within an open source software community: Rubinius. We analyze the ongoing management of interdependencies within the community and find that unresolved interdependencies are associated with alternatively structured sequences of activities, which we define as routines. In particular, we observe that two distinct classes of interdependencies-development and developer interdependencies-are associated with alternative forms of routine variation. We identify two generalized routine components-direct implementation and knowledge integration, which address these two distinct classes of unresolved interdependencies. In particular, direct implementation deals with development interdependencies within the code that are not already coordinated through modular interfaces, while knowledge integration resolves unaccounted interdependencies between developers. We conclude with implications for research into organizing principles for online communities and note the significance of our findings for the study of coordination in organization studies in general.","2016-12","2025-05-05 17:05:23","2025-05-05 17:05:23","","751-772","","4","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These formal standards are needed in the telecommunications market to achieve functional interoperability. The standardization process takes years, and then a vendor still needs to implement the resulting standard in a product. This prevents service providers (SPs) who are willing to venture into new domains from doing so at a fast pace. With the development of software-defined networking (SDN) and network function virtualization (NFV), opensource technology is emerging as a new option in the telecommunications market. In contrast to SDOs, open-source software (OSS) communities create a product that may implicitly define a de-facto standard based on market consensus. Therefore, SPs are drawn to OSS, but they face technical, procedural, legal, and cultural challenges due to their lack of experience with open software development. The question therefore arises, how the interaction between OSS communities, SDOs, and industry fora (IF) can be organized to tackle these challenges. This article examines the evolving roles of OSS communities, IF, and SDOs, and places them in an NFV/SDN context. It sketches the differences between these roles and provides guidelines on how the interaction between them can turn into a mutually beneficial relationship that balances the conflicting goals of timely development on the one hand and technical excellence, openness, and fairness on the other, to reach their common goal of creating flexible and efficient telecommunications networks.","2016-03","2025-05-05 17:05:23","2025-05-05 17:05:23","","46-53","","S","54","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software managers and developers use several measures to measure and improve the quality of a software solution throughout the development process. These measures assess the quality of different software attributes, such as product size, cohesion, coupling, and complexity. Researchers and practitioners use software metrics to understand and improve software solutions and the processes used to develop them. Determining the relationship between software metrics aids in clarifying practical issues with regard to the relationship between the quality of internal and external software attributes. We conducted an empirical study on two open source systems (JEDIT and ANT) to study the defectiveness Evolution in Open Source Software Systems. The result reveals that a good designed software has lesser defects and have high cohesion. Moreover the study also revealed that defects are higher in initial versions and most corrected errors are from major classes in initial version. Removal of defects also reveals that a good software is consistently improved and feed backs are important part of open source systems. (C) 2016 The Authors.

The objective of this study was to develop a greenhouse environment measurement system using a low-cost microcontroller with open-source software. Greenhouse environment parameters measured were air temperature, relative humidity, and carbon dioxide (CO2) concentration. The ranges of the temperature, relative humidity, and CO2 concentration were -40 to 120 degrees C, 0 to 100%, and 0 to 10,000 ppm, respectively. A 128 x 64 graphic LCD display was used for real-time monitoring of the greenhouse environments. An Arduino Uno R3 consisted of a USB interface for communicating with a computer, 6 analog inputs, and 14 digital input/output pins. A temperature/relative humidity sensor was connected to digital pins 2 and 3. A CO2 sensor was connected to digital pins 12 and 13. The LCD was connected to digital pin 1 (TX). The sketches were programmed with the Arduino Software (IDE). A measurement system including the Arduino board, sensors, and accessories was developed (totaling $244). Data for the environmental parameters in a venlo-type greenhouse were obtained using this system without any problems.

It combines discussions from several research projects as well as previous publications to present the scope of commercial choices within open source software and their consequences. Findings - The findings show that higher levels of involvement in open source software communities poses important questions about the balance between economic, technological, and social logics as well as the benefits of being autonomous, having access to collaborative networks and minimizing risks related to free-riding. There are six levels of commercial involvement in open source communities, and each of them is characterized by a different dilemma. Originality/value - The paper sheds light on the various level of involvement of business in open source movement and emphasize that the popularized “open innovation” concept is only the first step in real involvement and paradigm shift.","2016","2025-05-05 17:05:24","2025-05-05 17:05:24","","344-360","","3","29","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Interviews; Community; Qualitative research; Open source; Participation; Software; Open-source software; Linux; Venture capital; Software development; Codes; Business models; Mixed-methods; Case study; Public domain; Surveys & questionnaires; Freeware; Innovations; Open innovation; Literature reviews; Open; Commercialization; Contradictory institutional logics; Dilemma; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose Dolphin, a global OSS search engine, which leverage the crowd discussions around OSS across communities for optimizing software ranking. Dolphin employs the crowd wisdom as an important factor and combines it with the semantic similarity to optimize search results ranking.

However, the use of these tools for education purposes faces important barriers: the availability of the resources, the cost and the students' perception, among many others. These problems might be overcome by the use of free software simulators. In this paper, we present several experiences using free software tools in engineering Higher Education courses. The experiences shown cover several courses of different engineering Degrees: “Electronics and Automation”, “Electrical Engineering”, “Computing” and “Industrial Technologies”. These tools have been used in teaching activities for several years. As a result, the perceptions, gained experience and views of the teachers involved in the different courses are presented and discussed. Teachers specially valued the independence of the tools from commercial policies, as well as the suppression of expensive licenses. Additionally, they perceived that students understood better the simulations performed since all the parts of the tools could be freely accessed. They also remarked the possibility of changing the code at low level and fuse different free software projects together, what is not possible with the commercial tools. In addition, free software resources allowed students to start in a very common world currently, the collaborative communities, which may be of great importance in their future professional activities. However, teachers involved in these experiences also detected several drawbacks. In some cases, free software simulators are less robust than their commercial alternatives, which usually pay special attention at the design, being perceived by students as a signal of higher quality. In some simulators the documentation is incomplete, and there is a lack of easy-to-use examples which hinders the use of the tool by low-experienced users such as first-year students. The opportunities and threats faced by these tools are also discussed, concluding that when selecting an educational resource, the free software resources must be considered as perfectly valid options in the same conditions as the proprietary solutions.","2016","2025-05-05 17:05:24","2025-05-05 17:05:24","","8653-8662","","NA","NA","","","","EDULEARN Proceedings","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-84-608-8860-4 Place: NA Publisher: NA","","","","NA","","Chova, L.

From August to November 2014, a total of 95 patients with 104 gastric epithelial neoplasms underwent DFC-ESD (DFC group). Historical controls treated by conventional ESD (control group) were individually matched to cases at a 1:1 ratio by lesion location, ulcer findings, resected specimen size, and the proficiency of the operator (trainee/expert). The outcomes of the procedure in the two groups were then compared. The mean +/- A SD procedure time was 43 +/- A 24 min in the DFC group and 52 +/- A 30 min in the control group (P < 0.01). Fewer lesions in the DFC group needed > 80 min compared with the control group (3-vs-16 cases, P = 0.01). There were no significant differences in adverse events between the groups. Perforation and delayed bleeding occurred in one and four lesions, respectively, in the DFC group, and three and nine in the control group. En bloc resection was achieved in all cases. No significant differences were found regarding curability of ESD between the groups. DFC effectively reduced ESD procedure time without increasing adverse events.

E-portfolios with mobile capabilities allow even more flexibility. However, the development or acquisition of ePortfolio software is often costly, and at the same time, commercially available systems may not sufficiently fit the institution's needs. The aim of this study was to design and evaluate an ePortfolio system with mobile capabilities using a commercially free and open source software solution. Methods: We created an online ePortfolio environment using the blogging software WordPress based on reported capability features of such software by a qualitative weight and sum method. Technical implementation and usability were evaluated by 25 medical students during their clinical training by quantitative and qualitative means using online questionnaires and focus groups. Results: The WordPress ePortfolio environment allowed students a broad spectrum of activities - often documented via mobile devices - like collection of multimedia evidences, posting reflections, messaging, web publishing, ePortfolio searches, collaborative learning, knowledge management in a content management system including a wiki and RSS feeds, and the use of aid tools for studying. The students' experience with WordPress revealed a few technical problems, and this report provides workarounds. The WordPress ePortfolio was rated positively by the students as a content management system (67 % of the students), for exchange with other students (74 %), as a note pad for reflections (53 %) and for its potential as an information source for assessment (48 %) and exchange with a mentor (68 %). On the negative side, 74 % of the students in this pilot study did not find it easy to get started with the system, and 63 % rated the ePortfolio as not being user-friendly. Qualitative analysis indicated a need for more introductory information and training. Conclusions: It is possible to build an advanced ePortfolio system with mobile capabilities with the free and open source software WordPress. This allows institutions without proprietary software to build a sophisticated ePortfolio system adapted to their needs with relatively few resources. The implementation of WordPress should be accompanied by introductory courses in the use of the software and its apps in order to facilitate its usability.","2016-06-03","2025-05-05 17:05:25","2025-05-05 17:05:25","","NA","","NA","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There are various methods for identification, such as fingerprinting, odontostomatology and genetic fingerprinting, which presuppose the existence of reference material of the missing person; however, if there is no evidence of a person's identity the only possibility is often the use of forensic facial soft tissue reconstruction. This method is based on the high recognition level of a human face on the basis of bony structures of the skull and its anatomical features. The aim of this study was the design and application of a novel process for a computer-aided 3D facial soft tissue reconstruction on the basis of digital photographs of a skull. The facial soft tissue reconstruction was carried out on a selected forensic case and based on open source software. A complete facial soft tissue reconstruction of the deceased person was created based on 76 photographs of the skull taken with a Nikon D7100 SLR digital camera. The results show that for actual comparison images similar reconstruction results can be achieved. In addition, a model library for facial features was created. The presented workflow of a computer-aided 3D facial soft tissue reconstruction based on open source software is a cost-effective and flexible alternative to conventional reconstruction methods. It could be demonstrated that comparable reconstruction results can be achieved. Whether the reconstruction result actually leads to the recognition of the person depends on many other factors.","2016-04","2025-05-05 17:05:25","2025-05-05 17:05:25","","83-89","","2","26","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A ready made FLOSS Enterprise Resource Planning (ERP) System that offer great opportunities for cost reduction and quality improvement is always a wiser decision for Developing Countries' Small and Medium-sized Enterprises (SME) over getting a “From scratch” software solution. The aim of this paper is to provide further understanding of issues surrounding adoption of FLOSS ERP by SME in Developing Countries. We employed the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model to determine the strength of predictors for SMEs' managers and directors' intention to accept and use FLOSS ERP systems of better operational, tactical and strategical decision making. Questionnaires were administered to 200 SMEs' managers and directors in the Kingdom of Morocco, Republic of Tunisia and Republic of Ivory Coast, with 177 returned, a xx% return rate.

A preliminary study was done to explore the state of OSS implementation among government agencies since the launch of the Malaysian Public Sector OSS Master Plan on July 16, 2004. Semi-structured face-to-face interviews using open-ended questions were conducted with IT managers and IT officers in the Northern Region of Peninsular Malaysia. The preliminary study aimed at investigating the usage of OSS and proprietary software, the level of OSS utilisation, the level of OSS knowledge and training of ICT and non-ICT staff, software development and acquisition model, internal OSS manpower capabilities and skills, the user's perception of the advantages of OSS, the user's perception of the risks of OSS, and the problems or barriers in OSS implementation. The results of interviews show that there are many problems or barriers in OSS implementation, e.g. lack of internal OSS expertise, lack of OSS policy, and lack of top management support. Therefore, this study will test the hypotheses on the success factors to OSS implementation in the public sector and to propose a framework for successful OSS implementation in the Malaysian Public Sector. A quantitative approach using survey method via questionnaire will be performed to answer the research question where simple random sampling will be used.

The productivity of such development teams, i.e., how their size is related to the produced output, is an important consideration for project and schedule management as well as for cost estimation. The majority of studies in empirical software engineering suggest that - due to coordination overhead - teams of collaborating developers become less productive as they grow in size. This phenomenon is commonly paraphrased as Brooks' law of software project management, which states that “adding manpower to a software project makes it later”. Outside software engineering, the non-additive scaling of productivity in teams is often referred to as the Ringelmann effect, which is studied extensively in social psychology and organizational theory. Conversely, a recent study suggested that in Open Source Software (OSS) projects, the productivity of developers increases as the team grows in size. Attributing it to collective synergetic effects, this surprising finding was linked to the Aristotelian quote that “the whole is more than the sum of its parts”. Using a data set of 58 OSS projects with more than 580,000 commits contributed by more than 30,000 developers, in this article we provide a large-scale analysis of the relation between size and productivity of software development teams. Our findings confirm the negative relation between team size and productivity previously suggested by empirical software engineering research, thus providing quantitative evidence for the presence of a strong Ringelmann effect. Using fine-grained data on the association between developers and source code files, we investigate possible explanations for the observed relations between team size and productivity. In particular, we take a network perspective on developer-code associations in software development teams and show that the magnitude of the decrease in productivity is likely to be related to the growth dynamics of co-editing networks which can be interpreted as a first-order approximation of coordination requirements.","2016-04","2025-05-05 17:05:25","2025-05-05 17:05:25","","642-683","","2","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems.

The increased participation is an observable phenomenon; many researchers and practitioners assume that the practice of community sharing does not improve the bottom line, but rather believe the practice is altruistic in nature. Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, Why do for-profit corporations participate in the development of open source software? was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory. In this article, we examine interview responses and field study data from corporate members of open source communities to determine how they justify devoting time and effort to community engagement. Our study makes a contribution to open source software literature by revealing that numerous rational and emotional reasons exist for corporate participation in open source software development.","2016","2025-05-05 17:05:25","2025-05-05 17:05:25","","323-343","","4","26","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Open source; open source software; Participation; Software; Open-source software; Game theory; open source communities; Software development; Public domain; 51321:Software Publishers; 8302:Software & computer services industry; Software industry; Freeware; 9130:Experimental/theoretical; 2600:Management science/operations research; Cooperative game; Coopetition; Drama Theory; game theory; Business And Economics–Computer Applications","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results achieved by performance evaluation tools and testing of VoIP applications have proved it to be satisfactory. We have also satisfactorily implemented, configured and tested point to point Virtual Private Network (VPN) between MANET nodes using OSS (VPN Server, OpenVPN for Android, OpenVPN Connect).

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.","2016-05","2025-05-05 17:05:26","2025-05-05 17:05:26","","NA","","2","25","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY","","","","Measurement; natural experiment; Human Factors; commercial involvement; contributor retention; Hybrid project; \n contributor inflow; extent; intensity of\n involvement","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore in this paper, we investigate how to predict inter-cluster tie strength, and propose that inter-cluster tie strength can be predicted from determination of intra-cluster density.

Although some of the hosted projects are growing and have many developers, most projects are organized by a few developers and face difficulties in terms of sustainability. OSS projects depend mainly on volunteer developers, and attracting and retaining these volunteers are major concerns of the project stakeholders. To investigate the population structures of OSS development communities in detail and conduct software analytics to obtain actionable information, we apply a demographic approach. Demography is the scientific study of population and seeks to identify the levels and trends in the size and components of a population. This paper presents a case study, investigating the characteristics of the population structures of OSS projects on GitHub, and shows population projections generated with the well-known cohort component method. We found that there are four types of population structures in OSS development communities in terms of experiences and contributions. In addition, we projected the future population accurately using a cohort component population projection method. This method predicts a population of the next period using a survival rate calculated from past population. To the best of our knowledge, this is the first study that applied demography to the field of OSS research. Our approach addressing OSS-related problems based on demography will bring new insights, since studying population is novel in OSS research. Understanding current and future structures of OSS projects can help practitioners to monitor a project, gain awareness of what is happening, manage risks, and evaluate past decisions.","2016-05","2025-05-05 17:05:27","2025-05-05 17:05:27","","1304-1315","","5","E99D","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: KIKAI-SHINKO-KAIKAN BLDG, 3-5-8, SHIBA-KOEN, MINATO-KU, TOKYO, 105-0011,\n JAPAN Publisher: IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG","","","","OSS; software development communities; software population pyramids; \n demography","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is a waste of time and effort for project contributors to manually identify and reject them, especially in complex systems with many features. Our research is aiming to find a suitable solution to identify redundant feature requests in OSS projects. We have conducted a survey on a well-known Open Source community, Hibernate and gathered all of its feature requests up-to-date. Through studying and categorizing the characteristics of these feature requests, we have found that about 37% of the feature requests were rejected and the most common rejection reason was redundancy. Also we have found that it is very expensive to identify and resolve these redundant feature requests.

Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.","2016","2025-05-05 17:05:27","2025-05-05 17:05:27","","37-44","","NA","NA","","","","Proceedings of the European Conference on Knowledge Management","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-911218-03-6 Place: CURTIS FARM, KIDMORE END, NR READING, RG4 9AY, ENGLAND Publisher: ACAD CONFERENCES LTD","","","","knowledge sharing; communities of practice; free software communities; sharing profiles; \n clusters","","Moffett, S.; Galbraith, B.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is a totally new and diverse environment, in the sense that not only the projects but also their resources, e.g., developers change dynamically. There is no guarantee that developers will follow the same methodologies and quality policies as in a traditional and closed project. In such world, identifying rework causes is a necessary step to reduce project costs and to help project managers to better define their strategies. We observed that in real OSS projects there are no fixed team, but instead, developers assume some kind of auction in which the activities are assigned to the most interested and less-cost developer. This lead us to think that a more complex auctioning mechanism should not only model the task allocation problem, but also consider some other factors related to rework causes. By doing this, we could optimise the task allocation, improving the development of the project and reducing rework. In this paper we presented MAESTROS, a Multi-Agent System that implements an auction mechanism for simulating task allocation in OSS. Experiments were conducted to measure costs and rework with different project characteristics. We analysed the impact of introducing a Q-learning reinforcement algorithm on reducing costs and rework. Our findings correspond to a reduction of 31% in costs and 11% in rework when compared with the simple approach. Improvements to MAESTROS include real projects data analysis and a real-time mechanism to support Project Management decisions.","2016","2025-05-05 17:05:28","2025-05-05 17:05:28","","61-73","","NA","616","","","","Studies in Computational Intelligence","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-3-319-25017-5; 978-3-319-25015-1 Place: NA Publisher: NA","","","","NA","","Novais, P.; Camacho, D.; Analide, C.; Seghrouchni, A.

However, frequent personnel turnover and lack of organizational management makes it difficult to capture the actual development effort. Various OSS maintenance effort estimation approaches have been developed to provide a way to understand and estimate development effort. The goal of this study is to identify the current state of art of the existing maintenance effort estimation approaches for OSS. We performed a systematic literature review on the relevant studies published in the period between 2000-2015 by both automatic and manual searches from different sources. We derived a set of keywords from the research questions and established selection criteria to carefully choose the papers to evaluate. 29 out of 3,312 papers were selected based on a well designed selection process. Our results show that the commonly used OSS maintenance effort estimation methods are actual effort estimation and maintenance activity time prediction; the most commonly used metrics and factors for actual effort estimation are source code measurements and people related metrics; the most commonly mentioned activity for maintenance activity time prediction is bug fixing. Accuracy measures and cross validation is used for validating the estimation models. Based on the above findings, we identified the issues in evaluation methods for actual maintenance effort estimations and the needs for quantitative OSS maintenance effort inference from size-related metrics. Meanwhile, we highlighted individual contribution and performance measurement as a novel and promising research area.","2016","2025-05-05 17:05:28","2025-05-05 17:05:28","","32-43","","NA","NA","","","","Proceedings-IEEE International Conference on Software Maintenance","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn; NC State Univ ISBN: 978-1-5090-3806-0 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study shows that open source software has certain facets; code, community, coordination mechanisms, license and documentation. Each facet is not stable; indeed, it is changing and mutable. This creates possibilities, potential but also recalcitrance, and barriers. The interesting point of departure of our study is how open source software a much touted transparent and open phenomenon is by its nuanced and layered mutability able to make the process and practices surrounding it less visible. It concludes with clear policy recommendations developing from this research that could help to make open source adoption more sustainable in the public sector. (c) 2015 Elsevier Inc.

Free open-source software tools for documenting, analyzing, visualizing, and sharing using electronic notebooks","NA","","0022-3077","10.1152/jn.00137.2016","NA","Neurophysiology requires an extensive workflow of information analysis routines, which often includes incompatible proprietary software, introducing limitations based on financial costs, transfer of data between platforms, and the ability to share. An ecosystem of free open-source software exists to fill these gaps, including thousands of analysis and plotting packages written in Python and R, which can be implemented in a sharable and reproducible format, such as the Jupyter electronic notebook. This tool chain can largely replace current routines by importing data, producing analyses, and generating publication-quality graphics. An electronic notebook like Jupyter allows these analyses, along with documentation of procedures, to display locally or remotely in an internet browser, which can be saved as an HTML, PDF, or other file format for sharing with team members and the scientific community. The present report illustrates these methods using data from electrophysiological recordings of the musk shrew vagus-a model system to investigate gut-brain communication, for example, in cancer chemotherapy-induced emesis. We show methods for spike sorting (including statistical validation), spike train analysis, and analysis of compound action potentials in notebooks. Raw data and code are available from notebooks in data supplements or from an executable online version, which replicates all analyses without installing software-an implementation of reproducible research. This demonstrates the promise of combining disparate analyses into one platform, along with the ease of sharing this work. In an age of diverse, high-throughput computational workflows, this methodology can increase efficiency, transparency, and the collaborative potential of neurophysiological research.","2016-08","2025-05-05 17:05:29","2025-05-05 17:05:29","","252-262","","2","116","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Moxibustion releases a considerable amount of smoke into the environment. There remains controversy over the safety of moxa smoke and its potential effects on human health. Methods We measured the PM2.5 (particulate matter with aerodynamic diameter <2.5m) mass concentration in moxa smoke and the oxidative capacity of PM2.5 and moxa ash (using a plasmid scission assay in whole and water-soluble fractions) in the by-products of moxibustion produced from burning moxa floss of different ratios (3:1 or 15:1) and duration of storage (3 or 10years) in three simulated moxibustion clinics. Results PM2.5 mass concentration was 224.28, 226.39 and 210.56g/m(3) for samples A (3years and 3:1 ratio), B (3years and 15:1 ratio), and C (10years and 3:1 ratio), respectively. Average D-500 oxidative damage of PM2.5 was 29.42%, 29.16% and 27.01% and that of moxa ash was 22.78%, 20.60% and 21.42% for samples A, B and C, respectively. PM2.5 demonstrated a significantly greater oxidative capacity than moxa ash (p<0.05). Conclusions The oxidative DNA damage induced by individual PM2.5 following moxibustion was lower than that reported in other environments. However, PM2.5 mass concentration after moxibustion is still relatively high. We would recommend ensuring adequate ventilation during moxibustion to reduce any possible risks. Further studies are needed to better define the potential impact of particles in moxibustion by-products on human health.","2016-04","2025-05-05 17:05:30","2025-05-05 17:05:30","","101-106","","2","34","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the case of orthopaedic and dental implants it was found that geometry and surface topography are crucial for short and long-term success of the implant, due to its effects in osseointegration. Properties of implant surfaces have been studied in the last decade in a concentrated effort to improve osseointegration process and implant success. Several researchers have proved that roughness of implant surface is related to healing time and integration between the implants and the bone, but the parameters on the surface creation are not fully controllable with current processes. In this work, computational algorithms are proposed for implant surface design in order to control the parameters required for this application. As a result it is presented an open-source software tool, called POMES - Porous and Modifications for Engineering Surfaces - , to design porous/roughness on top of surfaces in any geometry.

Threedimensional models of the lesions were aligned and overlapped through the MeshLab software, which performed an automatic recording of the anatomical structures, based on the best fit. Qualitative and quantitative analyses of the changes in lesions size after treatment were performed with the 3DMeshMetric software. Results: The ITK-SNAP v. 3.0 showed the smaller value corresponding to the voxel count and the volume of the lesion segmented in yellow, indicating reduction in volume of the lesion after the treatment. A higher value of the mean intensity of the segmented image in yellow was also observed, which suggested new bone formation.

Due to this, many software fails to get repair within real time constraint. Ascribe to technology advancements and changing requirements, software must be well developed and maintained to get adapted. Hence, it is necessary to predict software maintainability in the early phases of the lifecycle so that optimization of resources can be possible and cost can be reduced. Software Maintainability is the quality attribute of software product that explains the ease with which modifications can be performed. The main focus in this study is to propose the use of Gene Expression Programming (GEP) for the software maintainability prediction and measure its performance with various machine leaning techniques such as Decision Tree Forest, Support Vector Machine, Linear regression, Multilayer Perceptron and Radial basis function neural network. The empirical study is conducted with the help of four open source datasets. Eleven bad smells are identified and is considered as maintenance effort. Results of this study show that GEP algorithm performs better than machine learning classifiers; hence it can be used as sound alternative in the prediction of software maintainability.

We examine two kinds of problem/project-behaviors: Individuals can set up projects around the formulation of new problems or join existing projects and define and/or work on subproblems within an existing problem. The choice between these two behaviors is influenced by the mode of communication. A communication mode with little a priori structure is the best mode for communicating about new problems (i.e., formulating a problem); empirically, it is associated with project launching behaviors. In contrast, more structured communication fits subproblems better and is related to project joining behaviors. Our hypotheses derive support from data from the FOSS community.Managerial summary: We study how the way in which individuals communicate influence the project-behaviors they engage in. We find that relatively unstructured communication is associated with the setting up new projects, while communication that is structured around an artifact is associated with joining projects. Our findings hold implications for understanding how management may influence project behaviors and problem-solving: Firms that need to concentrate on more incremental problem-solving efforts (e.g., because a sufficient number of attractive problems have already been defined) should create environments in which interaction is undertaken mainly via artifacts. On the other hand, if firms seek to generate new problems (e.g., new strategic opportunities), they should create environments in which open-ended, verbal conversation is relatively more important than artifact-based communication.

Materials and Methods: A comparison of two household surveys was carried out where mothers of the family were interviewed using a structured questionnaire in order to obtain demographic, behavioural and socioeconomic information. In total, 852 and 984 households were included in 1996 and 2009, respectively. Self-reported use of dental floss was assessed dichotomously (yes/no). Poisson regression models were fitted to study the association between sociodemographic variables with the use of dental floss. Proportion ratios (PR) and 95% confidence intervals (95% CI) were reported. Results: The proportion of dental floss use increased from 48% to 59% over 13 years. The probability of dental floss use increased 1.23 times from 1996 to 2009 (PR = 1.23; 95% CI 1.13-1.34).

Purpose: The primary aim of the study was to compare survival rates and marginal bone loss of Straumann SLActive implants placed in either BCP (test) or Bio-Oss (R) (DBB) (control) after sinus floor augmentation. The secondary aim was to calculate graft sinus height at different time points. Materials and Methods: Bilateral sinus floor augmentation was performed in a split mouth model. Eleven patients (mean age 67 years) received 100% BCP on one side and 100% DBB on the contralateral side. After 8 months of graft healing, 62 Straumann SLActive implants were placed. After 5 years of functional loading (6 years after augmentation) of implants, marginal bone levels and grafted sinus height were measured, and implant survival and success rates were calculated. Results: After 5 years of loading, all prosthetic constructions were in function although two implants were lost in each grafting material. The overall implant survival rate was 93.5% (91.7% for BCP, 91.3% for DBB, and 100% for residual bone). The success rates were 83.3% and 91.3% for BCP and DBB, respectively. There was no statistically significant difference in mean marginal bone level after 5 years between BCP (1.4 +/- 1.2 mm) and DBB (1.0 +/- 0.7 mm). Graft height reduction (GHR) after 6 years was limited to 6.6% for BCP and 5.8% for DBB. Conclusion: In this limited RCT study, the choice of biomaterial used for sinus floor augmentation did not seem to have any impact on survival rates and marginal bone level of the placed implants after 5 years of functional loading and GHR was minimal.","2016-10","2025-05-05 17:05:32","2025-05-05 17:05:32","","926-936","","5","18","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","biphasic calcium phosphate; bone substitutes; deproteinized bovine bone; \n sinus floor augmentation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This analytic distinction presents some limitations in explaining how coordination is reached in organizations characterized by distributed teams, scarce face to face meetings and fuzzy and changing lines of authority, as in free/libre open source software (FLOSS) development. Analyzing empirical illustrations from two FLOSS projects, we highlight the existence of a peculiar model, stigmergic coordination, which includes aspects of both implicit and explicit mechanisms. The work product itself (implicit) and the characteristics under which it is shared (explicit) play an under-appreciated role in helping software developers manage dependencies as they arise. We develop this argument beyond the existing literature by working with an existing coordination framework, considering the role that the codebase itself might play at each step. We also discuss the features and the practices to support stigmergic coordination in distributed teams, as well as recommendations for future research. (C) 2016 The Authors.

Generalized refractory chronic periodontitis is a periodontal condition that is resistant to conventional therapy. Management of this condition often is frustrating to both the patient and the clinician. Case Descriptions. The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. Conclusions and Practical Implications. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.","2016-12","2025-05-05 17:05:33","2025-05-05 17:05:33","","974-978","","12","147","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 211 E CHICAGO AVE, CHICAGO, IL 60611 USA Publisher: AMER DENTAL ASSOC","","","","allergy; chronic periodontitis; contact hypersensitivity; plasma cell; Treatment; dental\n floss","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Different needs create different complexities which represent a new challenge to Web application development. In order to ensure the timely delivery of a project, software providers offering this service choose to use Open Sources (OSS) as an alternative. Since OSS consist of an existing framework that can be implemented directly into the application, how far does this affect the complexity of the effort estimation? A number of research papers have outlined the efforts made to refine the complexity of this field. However, to our best knowledge a systematic overview of the research done on Web application development that involves OSS usage does not appear to exist. Hence, the aim of this paper is to conduct a systematic literature review (SLR) of OSS Web application development. For this purpose, 34 papers from a total of 67 papers were identified and studied. The findings of this study indicate that (a) no research has been carried out on the field mentioned; (b) there is no early effort estimation model for Web projects that involve the usage of OSS. Therefore, this work provides an overview of the field besides identifying future research possibilities.","2016","2025-05-05 17:05:33","2025-05-05 17:05:33","","1158-1167","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: HPCC Syst; IEEE; IEEE Power & Energy Soc; IBM Res; IBM Watson AI\n XPRIZE; Brown Univ; IEEE San Francisco PES Chapter; Univ Michigan ISBN: 978-1-5090-4171-8 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

There is one degree in Renewable Energy Engineering given at the Gipuzkoa Faculty of Engineering (Eibar). In the last year of their studies, students, can select one subject on Ocean Energy. In this subject, state-of-the-art operation and management techniques are taught to the students. Apart from the transmission of this knowlegde, the focus is practical and is based on hands-on computer real-life exercises, which involves not only intensive programming using a high-level software, but also the spatial representation of results. This is important because currently two major research and development lines can be identified as far as ocean energy is concerned. The first one is the analysis of prototypes that in the future will extensively extract electricity from wave farms. The second one is related to the resource itself, which implies the analysis and characterization of some ocean variables related to the extraction of energy. In many cases, the raw information on some oceanic variables of interest is available from institutions like the ECMWF http://www.ecmwf.int However a very extensive phase of data preprocessing is needed to extract useful information on wave energy potential. This will be an important task for future engineers involved in the spatial planning of oceanic energy facilities and in real-time forecasting and control of electricity obtained at wave farms. For this reason, students need to effectively learn to do all these tasks. R (https://www.cran.r-project.org/) is a freely available software that provides an optimum answer to these combined needs and teaching challenges due to its modular structure. R has a core module and nearly 8000 packages specifically developed for different purposes are also available. Packages like “RNetCDF”, “sp” “rgeos”, “rgdal”, “maps”, “maptools” and “mapdata” have been developed to make R work with full functionalities just like any high-level programming software. Incorporating R into the teaching activities of the subject “Ocean Energy” has represented an important step forward in the education of future engineers while providing them with real-life tools for their future jobs in wave farms.","2016","2025-05-05 17:05:33","2025-05-05 17:05:33","","8696-8702","","NA","NA","","","","EDULEARN Proceedings","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-84-608-8860-4 Place: NA Publisher: NA","","","","NA","","Chova, L.

In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes.

Since then, the traditional process of purchasing software has dramatically changed, challenged by the advent of open source software (OSS). Since its inception in the 1980s, OSS has matured, grown, and become one of the important driving forces of the enterprise ecosystem. However, it has also brought important IT security risks that are impacting the OSS IT adoption decision-making process. The recent Heartbleed bug demonstrated the grandeur of the issue. While much of the noise relates to the amplification of perceived risks by the popular mass media coverage, the effect is that many enterprises, mainly for risk reasons, have still chosen not to adopt OSS. We investigated “how do information security related characteristics of OSS affect the risk perception and adoption decision of OSS” by conducting an online survey of 188 IT decision-makers. The proposed Open Source Risk Adoption Model offers novel insights on the importance of the perceived risk antecedents. Our research brings new theoretical contributions, such as understanding the perceived IT security risk (PISR) relationship with adoption intention (AI) in the OSS context, for researchers and important insights for IT information professionals. We have found that IT security risk has a significant role in OSS adoption intention. Our results offer possible future research directions and extend existing theoretical understanding of OSS adoption.","2016-01","2025-05-05 17:05:34","2025-05-05 17:05:34","","151-185","","1","15","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such a scenario sometimes leads to a situation in which while an architect claims the use of a secure architecture in the form of some tactic, the corresponding source code does not support the claim. To bridge this gap, the first critical step is to verify whether the source code reflects at least some of the structural or behavioral features required for a tactic. In this study, we examine the extent of this discrepancy between an architect's vision of what security tactics need to be adopted in the software and the actual implementation.

This term includes a wide variety of experiences from time banks and urban gardens to startups or digital platforms. The recent expansion of all tthese initiatives can be linked to a combination of factors such as the technological development, economic recession and other overlapping crises (environmental, care, political.) and changing social values. During 2014-2015, two almost parallel studies were undertaken following a similar methodology. The first one was aimed at defining and identifying Collaborative Economy practices linked to Andalusia's public universities. The second study searched for entrepreneurship sharing initiatives in the region. The results led to the following question about the nature of the Collaborative Economy: Is it possible to define these practices as postcapitalist initiatives and do they promote a fairer and more equalitarian society or do they respond to capital forces and simply aim to continue extracting and privatizing value which is socially generated? This article analyses a specific set of initiatives identified in Andalusia, those based on open source software and digital production. Its conclusions are that, these initiatives are, up to a point, embedded with the hacker ethic and the logics of open knowledge. Therefore, they could be situated within the promotion of a global commons which is opposed to the hegemonic logics of netarchical capitalism.","2016","2025-05-05 17:05:35","2025-05-05 17:05:35","","141-168","","1","13","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We report here on the feasibility and efficacy of traction using dental floss with endoscopic clip to facilitate ESD versus conventional method for ESD trainees. Twenty simulated gastric lesions, paired with location and size, were created in porcine stomachs using a standard template. After a circular incision was made, submucosal dissection (control, n = 10) was performed with standard ESD, while the study (clip, n = 10) was performed with traction using dental floss and endoclip. Primary outcome was speed of submucosal dissection. Secondary outcome included frequency of submucosal injection and adverse event. Compared with controls, median procedure time was significantly shorter in the clip group (5.6 +/- A 1.1 vs. 13.6 +/- A 2.5 min, P = 0.003), with a significantly faster submucosal dissection time (1.8 +/- A 0.3 vs. 0.6 +/- A 0.1 cm(2)/min, P = 0.001) and less frequent submucosal injection (5.7 +/- A 0.6 vs. 8.5 +/- A 1.0 times, P = 0.024).

Abstractions of MPL systems are derived as finite-state transition systems. A transition system is obtained first by partitioning the state space of the MPL system into finitely many regions and then by associating a unique state of the transition system to each partitioning region. Relations among the states of the transition system are then set up based on the underlying dynamical transitions between the corresponding partitioning regions of the MPL state space. In order to establish formal equivalences, the obtained finite abstractions are proven either to simulate or to bisimulate the original MPL system. The approach enables the study of general properties of the original MPL system formalized as logical specifications, by verifying them over the finite abstraction via model checking. The article presents a new, extended and improved implementation of a software tool (available online) for the discussed formal abstraction of MPL systems, and is tested on a numerical benchmark against a previous version.","2016-03","2025-05-05 17:05:35","2025-05-05 17:05:35","","109-145","","1, SI","26","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER","","","","Difference-bound matrices; Discrete-event systems; Max-plus algebra; Model abstractions; Model checking; Piece-wise affine systems; \n Bisimulations; \n Transition systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Here we show that, while initially developed to analyze hyperspectral two-dimensional (spatial) maps, this tool can be beneficial as well to anyone interested in measuring spectral variations over one or two dimensions, these dimensions being time, temperature, and so on. Different possibilities offered by the software (preprocessing, simultaneous analysis of replicas, of different conditions, ROT calculation, multivariate analysis, determination of reaction rate constant and of Arrhenius plot) are illustrated with two examples. The first example is the Fourier transform infrared spectroscopy (FTIR) follow-up of the saponification of oil by lead compounds. The disappearance of reagent (oil) and formation of products (lead carboxylates and glycerol) can be easily followed and quantified. The second example is a combined extended X-ray absorption fine structure (EXAFS), diffuse reflectance infrared Fourier transform spectroscopy (DRIFT), and mass spectroscopy (MS) analysis of RhAl2O3 catalyst under NO reduction by CO in the presence of O-2.

Our findings confirm that women enter the FLOSS community later than men, do primarily other tasks than coding, participate less if they have children, and have slightly different reasons to enter (and to stay in) the development communities they join. However, we also find evidence that women are joining FLOSS projects in higher numbers in recent years, and that the share of women devoting few hours per week to FLOSS and full-time dedication is higher than for men.

Meta-analysis and meta-regression are statistical methods for synthesizing and modelling the results of different studies, and are critical research synthesis tools in ecology and evolutionary biology (E&E). However, many E&E researchers carry out meta-analyses using software that is limited in its statistical functionality and is not easily updatable. It is likely that these software limitations have slowed the uptake of new methods in E&E and limited the scope and quality of inferences from research syntheses. 2. We developed OpenMEE: Open Meta-analyst for Ecology and Evolution to address the need for advanced, easy-to-use software for meta-analysis and meta-regression. OpenMEE has a cross-platform, easy-to-use graphical user interface (GUI) that gives E&E researchers access to the diverse and advanced statistical functionalities offered in R, without requiring knowledge of R programming. 3. OpenMEE offers a suite of advanced meta-analysis and meta-regression methods for synthesizing continuous and categorical data, including meta-regression with multiple covariates and their interactions, phylogenetic analyses, and simple missing data imputation. OpenMEE also supports data importing and exporting, exploratory data analysis, graphing of data, and summary table generation. 4. As intuitive, open-source, free software for advanced methods in meta-analysis, OpenMEE meets the current and pressing needs of the E&E community for teaching meta-analysis and conducting high-quality syntheses. Because OpenMEE's statistical components are written in R, new methods and packages can be rapidly incorporated into the software.

This has led the clone research community to observe the effects of code clones on the code quality of FOSS projects. Although code clones are not always harmful but they might become critical to large scale and evolving software systems such as FOSS projects. Research in this paper reveals the importance and need for improving code quality of FOSS projects by implementing an effective clone management system integrated in the FOSS development environment. This paper proposes a clone management framework that ensures effective clone evolution tracking and visualization in FOSS projects.

Most of the existing software applications are nowadays distributed as Package-based Free and Open Source (PFOS) applications. Different requirements must be considered while configuring PFOS software. These requirements can be classified into two classes: dependency and capacity requirements.In this paper, we proposed a novel approach to ensure the correctness of elastic composite PFOS applications. Our approach is based on Event-B and combines proof-based models with model checking to provide a more complete verification. It starts by abstractly specifying the main concepts of PFOS software, and then refining them through multiple steps to model the elastic composite PFOS software and its correctness requirements. The consistency of each model and the relationship between an abstract model and its refinements are obtained by formal proofs. Finally, we used the ProB model-checker to trace possible design errors.","2017","2025-05-05 17:05:37","2025-05-05 17:05:37","","732–750","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-3-319-69461-0 Place: Berlin, Heidelberg Publisher: Springer-Verlag","","","","open source software; Verification; Free; Elasticity; Cloud; Composition; Event-B","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To fully leverage open source health information software platforms entails the availability of platform usage capacity, platform deployment capacity, platform customisation capacity and platform module development capacity. Most capacity building initiatives for information systems in developing countries have been short-term efforts focused on initial end user capacity to use such systems. However, to cope with rapid innovations and evolution associated with open source software platforms, capacity building ought to be a continuous process encompassing a range of human resource capacities not only use of the platform.","2017","2025-05-05 17:05:37","2025-05-05 17:05:37","","81-92","","NA","504","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: IFIP WG 9 4; Swedish Program ICT Developing Reg; Int Network\n Postgraduate Students ICT4D; UIINet; Cisco Indonesia; Sanata Dharma Univ ISBN: 978-3-319-59111-7; 978-3-319-59110-0 Place: NA Publisher: NA","","","","NA","","Choudrie, J.; Islam, M.

Architectural decay is caused by repeated, sometimes careless changes to a system during its lifespan. Despite decay's prevalence, there is a relative dearth of empirical data regarding the nature of architectural changes that may lead to decay, and of developers' understanding of those changes. In this paper, we take a step toward addressing that scarcity by introducing an architecture recovery framework, ARCADE, for conducting large-scale replicable empirical studies of architectural change across different versions of a software system. ARCADE includes two novel architectural change metrics, which are the key to enabling large-scale empirical studies of architectural change. We utilize ARCADE to conduct an empirical study of changes found in software architectures spanning several hundred versions of 23 open-source systems. Our study reveals several new findings regarding the frequency of architectural changes in software systems, the common points of departure in a system's architecture during the system's maintenance and evolution, the difference between system-level and component-level architectural change, and the suitability of a system's implementation-level structure as a proxy for its architecture.","2017-06","2025-05-05 17:05:37","2025-05-05 17:05:37","","1146-1193","","3","22","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Her men cultivate and punish their women when they resist naturalizing. Without denigrating the intelligence of women, von Arnim shows their unwitting complicity in their subjection. In The Pastor's Wife (1914) and in Vera (1921), the highly literate women have read the wrong books or missed the unfriendly truths about relationships in those they have read. The husbands and lovers make shallow use of philosophical and scientific reasoning to justify their control and enforce female uniformity deemed natural'. Darwin is misappropriated by the tyrannical Wemyss: evolutionary theories support his imperious dismissal of Lucy's aunt and friends. Wemyss's most monstrous actions suggest an atavistic patriarchal dominance like the hereditary reversion theorized by Samuel Butler as unconscious memory. Wemyss brings up the issue of England's inheritance, and a disturbing vision dawns as the philistine and self-appointed natural man subdues Lucy. Daphne du Maurier's Rebecca (1938) follows Vera's plot, but it does not interrogate naturalness in the same way. Entrapped in her husband's vision of a natural woman, the narrator registers Rebecca's wild transgressiveness as more powerful and universal than her own tamed naturalness.","2017","2025-05-05 17:05:37","2025-05-05 17:05:37","","115-129","","1-2, SI","28","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The novel's return to an earlier stage in the development of capital places the 1830s of the story in dialogue with the 1860s of its narration, while inviting readers to compare the values of this earlier period to those of their own. Considering this comparative structure in relation to nineteenth-century ethnography and its interlocutors-including Auguste Comte, Ludwig Feuerbach, and Karl Marx-I read Edward Tulliver's primitive materialism and the Dodson sisters' fetishism as both humorous reactions and more earnest forms of resistance to this increasing abstraction. Eliot ultimately turns toward the figurative possibilities of sublimation as a way to bridge the concrete and the abstract, the particular and the general, will and affect, self and other. Sublimation-not liquidation-therefore serves as the more apt metaphor for sympathy in the novel.","2017-12","2025-05-05 17:05:37","2025-05-05 17:05:37","","338-373","","3","72","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We propose a method to visualize software's structural differences using call graph. We have applied the method to a product development process and found that our method helps developers to speed up the application of OSS updates and reduce update errors. We have also found that solely providing call graph is insufficient for them to check the differences.

While CI has evidently improved aspects of the software development process, errors during CI builds pose a threat to development efficiency. As an increasing amount of time goes into fixing such errors, failing builds can significantly impair the development process and become very costly. We perform an in-depth analysis of build failures in CI environments. Our approach links repository commits to data of corresponding CI builds. Using data from 14 open-source Java projects, we first identify 14 common error categories. Besides test failures, which are by far the most common error category (up to >80% per project), we also identify noisy build data, e.g., induced by transient Git interaction errors, or general infrastructure flakiness. Second, we analyze which factors impact the build results, taking into account general process and specific CI metrics. Our results indicate that process metrics have a significant impact on the build outcome in 8 of the 14 projects on average, but the strongest influencing factor across all projects is overall stability in the recent build history. For 10 projects, more than 50% (up to 80%) of all failed builds follow a previous build failure. Moreover, the fail ratio of the last k=10 builds has a significant impact on build results for all projects in our dataset.","2017","2025-05-05 17:05:38","2025-05-05 17:05:38","","345-355","","NA","NA","","","","IEEE International Working Conference on Mining Software Repositories","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISBN: 978-1-5386-1544-7 Place: NA Publisher: IEEE Press","","","","mining software repositories; continuous integration; build errors; correlation analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of our study is twofold. Firstly, the results of our analysis provide insights on the possible discrepancies that are observed between the initial theoretical representations of learning processes and the real behavior captured in FLOSS event logs, constructed from mailing archives.

There is no work, to the best of our knowledge, which takes a combined view of various dimensions of a change. This study examines the change activity in 106 OSS projects from three points of view: change purpose (type), change size, and change effort. The common patterns in change type, change size, and change effort are highlighted using the burst detection technique. The burst detection technique helps in identifying the peaks in the time series and compares them with the peaks of other time series. The results indicate that the change-type activity of OSS projects is significantly related with change effort, and change size for high and moderate-activity clusters.

Core contributors and peripheral contributors work together to create a successful project, each playing a different role. One-Time Contributors (OTCs), who are on the very fringe of the peripheral developers, are largely unstudied despite offering unique insights into the development process. In a prior survey, we identified OTCs and discovered their motivations and barriers. Aims: The objective of this study is to corroborate the survey results and provide a better understand of OTCs. We compare OTCs to other peripheral and core contributors to determine whether they are distinct. Method: We mined data from the same code-review repository used to identify survey respondents in our previous study. After identifying each contributor as core, periphery, or OTC, we compared them in terms of patch size, time interval from submission to decision, the nature of their conversations, and patch acceptance rates. Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate. The peripheral developers fall in between the OTCs and the core contributors. Conclusion: OTCs do, in fact, face the barriers identified in our prior survey. They represent a distinct group of contributors compared to core and peripheral developers.","2017","2025-05-05 17:05:39","2025-05-05 17:05:39","","1-10","","NA","NA","","","","International Symposium on Empirical Software Engineering and\n Measurement","","","","","","English","","","","","","","Backup Publisher: ACM; IEEE; IEEE Comp Soc; IBM ISBN: 978-1-5090-4039-1 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In Indonesia alone, 25% of South East Asia's mangroves are at a risk. The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was “Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang” held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes. Field work activity conducted and confirmed the changes that occurred in the study areas. Our study shows that all of the two districts exhibit successfulness of the plantation program. Ground truth survey confirmed that the successfulness of the plantation program is due to the participation of communities in the area of study. This study also shows that by using open source software and freely available satellite images, the fast, robust, and reliable data as an initial step to monitor both short-term and long-term plantation program can be collected effectively and inexpensively.","2017-08","2025-05-05 17:05:39","2025-05-05 17:05:39","","251-259","","3","9","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: IR SUTAMI 36 A, SURAKARTA, 57126, INDONESIA Publisher: UNIV SEBELAS MARET","","","","Classification; Indramayu; Landsat TM/ETM+/OLI; mangroves; Subang; remote\n sensing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The problem becomes more evident in cases of complex combinations of software that carries different - often conflicting - licenses. In this paper we are presenting our work on automating license compatibility by proposing a process that examines the structure of Software Package Data Exchange (SPDX) for license compatibility issues assisting in their correct use and combination. We are offering the possibility to detect license violations in existing software projects and make suggestions on appropriate combinations of different software packages.

While already being used for clinical application, the complex interplay between these parameters requires thorough validation via simulations. These simulations required a realistic, controlled and adaptable model of the white matter axons with the surrounding myelin sheath. While there already exist useful algorithms to perform this task, none of them combine optimisation of axon packing, presence of myelin sheath and availability as free and open source software. Here, we introduce a novel disk packing algorithm that addresses these issues. The performance of the algorithm is tested in term of reproducibility over 50 runs, resulting density, and stability over iterations. This tool was then used to derive multiple values of FVF and to study the impact of this parameter on fr and MVF in light of the known microstructure based on histology sample. The standard deviation of the axon density over runs was lower than 10(-3) and the expected hexagonal packing for monodisperse disks was obtained with a density close to the optimal density (obtained: 0.892, theoretical: 0.907). Using an FVF ranging within [0.58, 0.82] and a mean inter-axon gap ranging within [0.1, 1.1] mu m, MVF ranged within [0.32, 0.44] and fr ranged within [0.39, 0.71], which is consistent with the histology. The proposed algorithm is implemented in the open-source software AxonPacking (hups://github.comineuropoly/ axonpacking) and can be useful for validating diffusion models as well as for enabling researchers to study the interplay between microstructure parameters when evaluating qMRI methods.","2017-01-31","2025-05-05 17:05:39","2025-05-05 17:05:39","","NA","","NA","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To do this, I begin by striking a dialectic between John Milbank's theological and David Graeber's anthropological conceptions of gift economies, illuminating crucial aspects of each to uncover what alternative economic principles are applicable to standard capitalist economic ideologies. I then turn to a practical application of where these gift economy ideologies are already being utilized to a degree, arguing specifically that open source software provides an alternative economic logic for countless members of the technology sector. On a broad level, I hope to show that capitalism provides the means to alter itself within its own ethos, as certain economic ideologies like gift economies - could potentially assuage those economic models that contribute to economic inequality. By accentuating these alternative logics within technology firms, they can be expanded and made more substantial, subsequently altering capitalism from the inside out.","2017","2025-05-05 17:05:39","2025-05-05 17:05:39","","5-21","","1","18","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To address this gap, we propose an approach to identify the core cross-cutting members and their roles within the community through analyzing email communication repositories. We use Social Network Analysis (SNA) tools to identify the most active core members in different forums (that have different focus such as Python-dev that focuses on language evolution and Python Lists that focus on user support), and their activities over time, thus identifying the core developers and their involvement in different community mailing lists. Based on the involvement of a core developer and the overall social structure of the network of core developers, we also present an approach for identifying a potential replacement for a community administrator that steps down. Using email repositories of six main Python forums as the case study domain, we computed several social network analysis metrics to characterize the core developers and their importance in the Python community.","2017","2025-05-05 17:05:39","2025-05-05 17:05:39","","308-317","","NA","NA","","","","Asia-Pacific Software Engineering Conference","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-1-5386-3681-7 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","Social Network Analysis; Python; Open Source Software Development; \n Community Development","","Lv, J.; Zhang, H.; Hinchey, M.; Liu, X.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Celeris is an open source software which needs minimum preparation to run on a Windows machine. The software solves the extended Boussinesq equations using a hybrid finite volume finite difference method and supports moving shoreline boundaries. The simulation and visualization are performed on the GPU using Direct3D libraries, which enables the software to run faster than real-time. Celeris provides a first-of-its-kind interactive modeling platform for coastal wave applications and it supports simultaneous visualization with both photorealistic and colormapped rendering capabilities. We validate our software through comparison with three standard benchmarks for non-breaking and breaking waves. Program summary Program title: Celeris Program Files doi: http://dx.doi.org/10.17632/5djwvf5x5k.1 Licensing provisions: GNU General Public License 3 (GPL) Programming language: C++, HLSL Nature of problem: Boussinesq-type models provide the research-level accuracy needed for modeling wave propagation in coastal zones. However the current models, both commercial and open source, do not provide means for real-time computation, nor provide model interactivity and concurrent visualization. In order to achieve a real-time simulation speed in current parallelized models, dozens to hundreds of CPU cores are needed. Celeris is an interactive software which provides faster than real-time simulation and visualization speed on an average user laptop. The novelty of this software is its interactive environment, which allows the user to modify the model and field parameters as the model is running, and to see the effect of these changes immediately. Solution method: A hybrid finite volume-finite difference scheme is used to solve the extended Boussinesq equations. The solver is parallelized using shader programming with Direct3D libraries. Visualization is also performed with the same libraries. (C) 2017 Elsevier B.V.

By knowing this licensing effect through scientific publications and their experience, project managers became able to act strategically, loosening up the restrictions associated with their source code due to sponsor interests, for example; or the contrary, tightening restrictions up to guarantee source code openness, adhering to the “forever free” strategy. But, have project managers behaved strategically like that, changing their projects license? Up to this paper, we did not know if and what types of changes in these legal allowances project managers have made and, more importantly, whether such managerial interventions are associated with variations in intervened project attractiveness (i.e., related to their numbers of web hits, downloads and members). This paper accomplishes these two goals and demonstrates that: 1) managers of free and open source software projects do change the distribution rights of their source code through a change in the (group of) license(s) adopted; and 2) variations in attractiveness are associated with the strategic choice of a licensing schema. To reach these conclusions, a unique dataset of open source projects that have changed license was assembled in a comparative form, analyzing intervened projects over its monthly periods of different licenses. Based on a sample of more than 3500 active projects over 44 months obtained from the FLOSSmole repository of Sourceforge.net, 756 projects that had changed their source code distribution allowances and restrictions were identified and analyzed. A dataset on these projects' type of changes was assembled to enable a descriptive and exploratory analysis of the types of license interventions observed over a period of almost four years anchored on projects' attractiveness. More than 35 types of interventions were detected. The results indicate that variations in attractiveness after a license intervention are not symmetric; that is, if a change from license schema A to B is beneficial to attractiveness, a change from B to A is not necessarily prejudicial. This and other interesting findings are discussed in detail. In general, the results here reported support the current literature knowledge that the restrictions imposed by the license on the source code distribution are associated with market success vis-a-vis project attractiveness, but they also suggest that the state-of-the-science is superficial in terms of what is known about why these differences in attractiveness can be observed. The complexity of the results indicates to free software managers that no licensing schema should be seen as the right one, and its choice should be carefully made, considering project strategic goals as perceived relevant to stakeholders of the application and its production. These conclusions create awareness of several limitations of our current knowledge, which are discussed along with guidelines to understand them deeper in future research endeavors.","2017-08-07","2025-05-05 17:05:40","2025-05-05 17:05:40","","NA","","NA","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: Av.

Their underlying technical interests, expertise, and working habits are indirectly delineated by their personal contributions. This paper is to discover the individualized contribution features of developers by latent Dirichlet allocation (LDA) approach. Dominant latent topics of each developer and the corresponding topic coverage degree are extracted from the source codes committed to the project repository, and such topic model is validated to be feasible for representing the individualized contribution features by statistics tests. Four types of topic evolution patterns are observed from the commit history of a developer. Temporal locality is partially exhibited in the topic evolution but there usually exhibit drastic changes between time-adjacent contributions of a developer. Respective proportions of the four evolution patterns and the degree of temporal locality in the topic evolution delineate a developer's individualized working habits in the time dimension. It is also proved that the correlation among the topic models of different developers is not equivalent to the real social collaborations among them. The outcome of this study would help OSS project coordinators get deep understanding on the work preferences and behavioral patterns of team members, thus facilitate project coordination activities such as task allocations.","2017-02","2025-05-05 17:05:40","2025-05-05 17:05:40","","91-124","","1","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

CoRain compares two parallel rain series (with an overlapping period) and tries to highlight overestimations and underestimations due to rain gauges in a specific condition, so that the user can consider it for future analysis. CoRain offers many information on the two analyzed series, starting with cleaning input data, comparing them and classifying rainy days by severity. CoRain is a cross-platform software, easily adaptable to different needs, that takes in input a single text file with daily information of the two rain series and outputs tables (in CSV format) and plots (as PNG images) that help in the interpretation of the data. Use of the program is very simple: the execution can be either interactive or non-interactive. CoRain code has been tested on different rain series in the Piedmont region (northwestern Italy), showing its importance in identifying climate variations and instrumentation errors.","2017-09","2025-05-05 17:05:40","2025-05-05 17:05:40","","405-416","","3","10","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although developers can find useful software assets to reuse in the OSS environment, they may face difficulties in finding solutions to problems that occur while integrating the assets with their own software. In OSS, sharing the experiences of solving similar problems among developers usually plays an important role in reducing problem-solving efforts. We analyzed how developers interact with each other to solve problems in OSS, and found that there is a common pattern of exchanging information about symptoms and causes of a problem. In particular, we found that many problems involve multiple symptoms and causes and it is critical to identify those symptoms and causes early to solve the problems more efficiently. We developed a Bayesian network based approach to semiautomatically construct a knowledge base for dealing with problems, and to recommend potential causes of a problem based on multiple symptoms reported in OSS. Our experiments showed that the approach is effective to recommend the core causes of a problem, and contributes to solving the problem in an efficient manner. (C) 2016 Elsevier Inc.

OSS project leaders implement quality controls to improve the quality of developed products. They may not be aware that their implementation of quality controls produces a side effect-quality controls signal unobservable project quality to volunteers and promote volunteers' continued participation intentions (VCPI). We focus on two quality controls-accreditation and code acceptance, which, respectively, map to the input and output quality of an OSS project-and compare their respective effects on VCPI in community-founded and spinout projects. We propose that accreditation and code acceptance influence VCPI by signaling unobservable input and output quality to volunteers. As we focus on continued participation, we theorize as to how volunteers' tenure in OSS projects moderates the relationships between the signaling effects of input and output quality controls and VCPI. Furthermore, we theorize as to how the OSS project type moderates the effects of quality controls on VCPI. We surveyed 304 volunteers from 40 OSS projects and constructed a two-level model of project and developer factors to explain VCPI. Our findings indicate that both accreditation and code acceptance enhance VCPI. The signaling effects on VCPI associated with accreditation decline with volunteer tenure, but those associated with code acceptance do not. Accreditation and code acceptance influence VCPI, with community-founded projects exhibitingweaker direct positive effects and spinout projects exhibiting stronger direct positive effects. We discuss the theoretical and practical implications of these findings.","2017-09","2025-05-05 17:05:41","2025-05-05 17:05:41","","603-625","","3","28","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On this rationale, this study was carried out to explore the applicability of the concept of converging `Free and Open Source Software (FOSS)' to promote sustainable knowledge sharing amongst the agricultural communities in Sri Lanka. A multi-stage community consultative process with a set of designated officials (”Sponsors”) and a series of semi-structured questionnaire survey with a cross section of smallholder agriculture farmers (n=246), were carried out in the Batticaloa, Kurunegala and Puttalam districts to gather the baseline data. This was followed by a number of field experiments (”Campaigns”) with the farmers (n=340) from same geographical areas. The two FOSS, namely: (1) “FrontlineSMS” for `Text Messaging' and (2) “FreedomFone” for `Interactive Voice Responses', were applied to evaluate the effectiveness of knowledge sharing within the farming communities. It was found that FOSS intervention increases the `Text messaging' and `Voice Call' usage in day-to-day agricultural communication by 26 and 8 percent, respectively. The demographic factors like age and educational level of the farmers have a positive influence on the knowledge sharing process. And also the `Mobile Telephony' was the most extensive mode of communication within the communities. The outcome of analysis, as a whole, implies that, with a fitting mechanism in place, this approach can be promoted as a “drive for positive changes” in agriculture-based rural communities in developing countries like Sri Lanka, and those in South and East Asia with similar socioeconomic and cultural perspectives.","2017","2025-05-05 17:05:41","2025-05-05 17:05:41","","351-359","","2","111","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VIA ANTONIO COCCHI 4, FLORENCE, 50131, ITALY Publisher: AGENZIA ITALIANA COOPERAZIONE SVILUPPO-ITALIAN DEV COOP AGENCY","","","","FOSS; Information; Knowledge sharing; Agricultural community","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We performed a quantitative and qualitative analysis of three OSS projects. Finding shows that software firms emphasize the co-creation of common value and partly react to the potential competitiveness on OSS ecosystems. Six themes about coopetition were identified, including spanning gatekeepers, securing communication, open-core sourcing and filtering shared code.

The study is based on mailing lists, interviews and observations. Findings - The study reveals that deliberate change is indeed achievable in a non-hierarchical collaborative OSS community context. However, it presupposes the presence and active involvement of informal change agents. The paper identifies and specifies four key drivers for change agents' influence. Originality/value - The findings contribute to organisational analysis by providing a deeper understanding of the importance of leadership in making deliberate change possible in non-hierarchical settings. It points to the importance of “change-by-conviction”, essentially based on voluntary behaviour.

The projects and developers co-evolve in an ecosystem. To keep healthy evolution of such OSS ecosystems, there is a need of attracting and retaining developers, particularly project leaders and core developers who have major impact on the project and the whole team. Therefore, it is important to figure out the factors that influence developers' chance to evolve into project leaders and core developers. To identify such factors, we conducted a case study on the GNOME ecosystem. First, we collected indicators reflecting developers' subjective willingness to contribute to the project and the project environment that they stay in. Second, we calculated such indicators based on the GNOME dataset. Then, we fitted logistic regression models by taking as independent variables the resulting indicators after eliminating the most collinear ones, and taking as a dependent variable the future developer role (the core developer or project leader). The results showed that part of such indicators (e.g., the total number of projects that a developer joined) of subjective willingness and project environment significantly influenced the developers' chance to evolve into core developers and project leaders. With different validation methods, our obtained model performs well on predicting developmental core developers, resulting in stable prediction performance (0.770, F-value).","2017-03","2025-05-05 17:05:42","2025-05-05 17:05:42","","396-414","","2","32","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Science; Open source software; Computers; Leadership; Studies; Collaboration; Open source; Computer science; Software; Regression analysis; Evolution; Case studies; Software development; Software ecosystem; Public domain; Software Projects; Developer; Dependent variables; Independent variables; Indicators; Logistic regression; Performance prediction; Regression models; United States–US; Research & development–R&D","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This would help software developers to judiciously allocate the resources used for testing and maintenance. Software metrics can be used for constructing various classification models which can be used for timely identification of change prone classes. Search based algorithms which form a subset of machine learning algorithms can be utilized for constructing prediction models to identify change prone classes of software. Search based algorithms use a fitness function to find the best optimal solution among all the possible solutions. In this work, we analyze the effectiveness of hybridized search based algorithms for change prediction. In other words, the aim of this work is to find whether search based algorithms are capable for accurate model construction to predict change prone classes.

Method and Result: A 77-year-old woman with a non-healing anteromedial chest wound presented with sudden hypotension and hemoptysis. The computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of ascending aorta, with sternal erosion close to the wound. Conventional open repair was not preferred due to possible contamination of interposition graft and difficult sternum closure. The feasibility of endografting was confirmed based on appropriate landing zones. After endografts modification at back table, we made a left minithoracotomy and establish a through-and-through body floss wire from left ventricular apex to femoral artery. Retrograde delivery over this wire from femoral artery to ascending aorta and deployment of endografts under rapid ventricular pacing support were performed smoothly. Final angiography showed no endoleaks with patent coronary and arch vessels. Further wound debridement was done at the same time and wound culture yielded tuberculosis.

Henceforth, Literature witnesses the evolution of SRGMs in terms of different assumptions, parameters, performance etc. This study is an attempt to model reliability growth phenomenon for Open Source Software (OSS). As the development process followed by OSS significantly differs from proprietary software, traditional software engineering SDLC models can't be followed for its development. OSS development procedure does not incorporate a dedicated testing phase and therefore negligible effort expenditure is done on testing of software prior its release. The volume of volunteer participation in its operational phase thus becomes a significant criterion in the representation of its reliability growth. Also, the impact of sudden changes in fault detection process (change-point) due to several reasons like variations in fault density, irregular team size, volunteer expertise etc is captured in proposed SRGM. This paper suggests a reliability model based on user growth with the concept of change point to better cater the heterogeneity in software failure process. Failure data of GNOME 2.0 is used in this paper reliability growth analysis. Unknown parameters are estimated using Least Square Estimation regression technique. Performance inspection of proposed SRGM is carried out using goodness-of-fit criteria like Mean square error (MSE), Coefficient of Determination (R-2), Predictive Ratio Risk (PRR), and Predictive Power (PP). The study recommends that introduction of the change-point in SRGM improves prediction capability of the model and hence establishes an evidence of its applicability.","2017","2025-05-05 17:05:42","2025-05-05 17:05:42","","248-253","","NA","NA","","","","International Conference on Reliability Infocom Technologies and\n Optimization Trends and Future Directions","","","","","","NA","","","","","","","Backup Publisher: Amity Univ Uttar Pradesh, Amity Inst Informat Technol; Comp Soc India;\n IEEE; IEEE UP Sect ISBN: 978-1-5090-3012-5 Place: NA Publisher: NA","","","","NA","","Shukla, B.; Khatri, S.

Most risks or security vulnerabilities, besides inadverted errors, originates from criminal activity, which anonymously thrives on the Web and can outbreak any organization, mainly for profit but sometimes just for the challenge of doing it. Consequently, creating and managing a security system is often the main form of precaution and it is the solution that guarantees better success rates. In this paper, we are interested in software with a lower financial cost, therefore our focus is in Free and Open Source Software.

We present a systematic mapping that covers two contexts of OSS evolution studies conducted so far, i.e., OSS evolution prediction and OSS evolution process support. We selected 98 primary studies from a large dataset that includes 56 conference, 35 journal and 7 workshop papers. The major focus of this systematic mapping is to study and analyze metrics, models, methods and tools used for OSS evolution prediction and evolution process support. We identified 20 different categories of metrics used by OSS evolution studies and results show that SLOC metric is largely used.

Characterization of the pristine milkweed floss and extracted cellulose was performed by chemical composition analysis, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The extracted cellulose had mainly a-cellulose as the other components hemicellulose and lignin were significantly removed during cellulose extraction process. The FTIR spectra also indicated that the chemical treatments extensively removed hemicellulose and lignin from the pristine milkweed floss. SEM technique was used to investigate the surface morphology of the pristine milkweed floss and extracted cellulose. The intensity of the crystalline peak in the X-ray diffractograms of the extracted cellulose was higher than that of pristine milkweed. Further, the XRD results indicated a structural transformation of cellulose I (pristine milkweed) to cellulose II (extracted cellulose) because of the chemical treatments. The extracted cellulose, which is a high biomass, had better thermal stability than the pristine milkweed floss owing to removal of non-cellulosic components.","2017","2025-05-05 17:05:43","2025-05-05 17:05:43","","2677-2683","","17","52","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although a plethora of software for the acquisition of eye-tracking data exists, they often exhibit critical issues when pervasive eye tracking is considered, e. g., closed source, costly eye tracker hardware dependencies, and requiring a human supervisor for calibration. In this paper, we introduce EyeRecToo, an open-source software for real-time pervasive head-mounted eye-tracking. Out of the box, EyeRecToo offers multiple real-time state-of-the-art pupil detection and gaze estimation methods, which can be easily replaced by user implemented algorithms if desired. A novel calibration method that allows users to calibrate the system without the assistance of a human supervisor is also integrated. Moreover, this software supports multiple head-mounted eye-tracking hardware, records eye and scene videos, and stores pupil and gaze information, which are also available as a real-time stream. Thus, EyeRecToo serves as a framework to quickly enable pervasive eye-tracking research and applications.

Education studies have also analysed the importance of these communities in spreading and sharing knowledge and educational culture has looked to these organizational forms for inspiration. At the same time, the link between these experiences and the development of pedagogical models emerging from cognitive sciences, systemic theory and the new forms of constructivism, which have generated a fruitful theory/practice circle, has been reinforced. The aim of this paper is to analyse the particular type of organizational, communicative and productive context of Open Communities: Free Software Communities, to understand how they work, their efficacy and to show their close link with dynamics and relations of an educational, formative and didactic type. Learning communities can still learn strategies of communication, organization and socialization from these communities, as well as the value of motivation and the importance of freedom and circulation of knowledge in order to build up efficient communities. We can also gain the understanding that the success of these communities depends on the fact that they are educational communities, therefore education studies can convey values, models and a culture of sharing to other sectors as well, such as the one taken into consideration: Free Software Communities.

Closed-loop experiments provide unique insights into brain dynamics and function. To facilitate a wide range of closed-loop experiments, we created an open-source software platform that enables high-performance real-time processing of streaming experimental data. Approach. We wrote Falcon, a C++ multi-threaded software in which the user can load and execute an arbitrary processing graph. Each node of a Falcon graph is mapped to a single thread and nodes communicate with each other through thread-safe buffers. The framework allows for easy implementation of new processing nodes and data types. Falcon was tested both on a 32-core and a 4-core workstation. Streaming data was read from either a commercial acquisition system (Neuralynx) or the open-source Open Ephys hardware, while closed-loop TTL pulses were generated with a USB module for digital output. We characterized the round-trip latency of our Falcon-based closed-loop system, as well as the specific latency contribution of the software architecture, by testing processing graphs with up to 32 parallel pipelines and eight serial stages. We finally deployed Falcon in a task of real-time detection of population bursts recorded live from the hippocampus of a freely moving rat. Main results. On Neuralynx hardware, round-trip latency was well below 1 ms and stable for at least 1 h, while on Open Ephys hardware latencies were below 15 ms. The latency contribution of the software was below 0.5 ms. Round-trip and software latencies were similar on both 32- and 4-core workstations. Falcon was used successfully to detect population bursts online with similar to 40 ms average latency. Significance. Falcon is a novel open-source software for closed-loop neuroscience. It has sub-millisecond intrinsic latency and gives the experimenter direct control of CPU resources. We envisage Falcon to be a useful tool to the neuroscientific community for implementing a wide variety of closed-loop experiments, including those requiring use of complex data structures and real-time execution of computationally intensive algorithms, such as population neural decoding/encoding from large cell assemblies.","2017-08","2025-05-05 17:05:44","2025-05-05 17:05:44","","NA","","4","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: TEMPLE CIRCUS, TEMPLE WAY, BRISTOL BS1 6BE, ENGLAND Publisher: IOP PUBLISHING LTD","","","","open-source software; closed-loop neuroscience; multi-threaded software; real-time processing; \n online burst detection","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Prior studies of open source governance have largely focused on its changing nature over time. In this work, we argue that the nature of governance varies across open source communities, and, in its evolution, multiple traces of authority may co-exist. We propose that such multiplicity can be understood by close examination of the authoritative structures embedded in coordination processes. We collected eight years of data on the coordination related to version control of the Linux kernel. Drawing on in-depth qualitative analysis, we investigate how coordination processes with different authoritative structures come together in the governance of open source software. We trace four coordination processes (autocratic clearing, oligarchic recursion, federated self-governance, and meritocratic idea-testing), each grounded in different authoritative structures (autocracy, oligarchy, federation, meritocracy) with their own form of legitimation. We offer a two-fold contribution in this paper. First, we enhance the open source governance literature by advancing a new theoretical perspective in which governance is seen as a configuration of coordination processes. Configurations give complementary support and are a source of tension and renewal. Second, we articulate a view on the conceptual relationship between governance and coordination where these concepts are understood as a duality, both working together to give rise to efficient and dynamic organizing in open source.","2017-06","2025-05-05 17:05:44","2025-05-05 17:05:44","","116-135","","2","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This project seeks to help satisfy that demand by analyzing health data and designing a web portal to support patient healthcare decisions. The portal is powered by SEMantic Open Source Software (SEMOSS), an end-to-end analytics tool. The project aims to adapt SEMOSS's capabilities to make healthcare data accessible to the patient population and healthcare stakeholders. To achieve this goal, publiclyavailable data about doctors in the state of Virginia and hospitals across the United States was gathered. Visualizations were created to answer potential patient questions about doctors, such as which nearby practitioner has the most experience. Data from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, in conjunction with Census Bureau data, was explored. The census information facilitated classification of each hospital as urban or rural based on location. Multiple linear regression and random forest analysis were used to determine which elements of patient experience most influence whether a patient would recommend a hospital. Outputs from the multiple linear regression models indicated that of the statistically significant predictors, doctor communication and staff responsiveness most impacted recommendation scores in rural hospitals, and nurse communication and pain management were the most impactful for urban hospitals. Random forest analysis indicated that staff responsiveness and nurse communication were the most important variables in determining high or low recommendation scores for rural hospitals, and care transition and nurse communication were the most important variables for urban hospitals. These results will be used to create filtering options for the SEMOSS patient portal.","2017","2025-05-05 17:05:44","2025-05-05 17:05:44","","144-149","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-5386-1848-6 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is particularly challenging in Free and Open Source Software (FOSS) ecosystems, in which hundreds of loosely connected developers and their projects are coordinated to release software to a schedule. To better understand this process and its challenges, we analyzed over two and half years of communication in the GNOME ecosystem and studied developers' interactions. Through a case study, we cataloged communication channels, determined the main channel from which we categorized high level communication and coordination activities spanning five releases, and triangulated our results by interviewing ten key developers. We found that a release schedule, influence (instead of direct control), and diversity are the main factors that positively impact the release process in the GNOME ecosystem. We report a set of lessons learned that encapsulates our understanding of how the Release Management process function in a FOSS ecosystem, we learned that: (1) ensure that the release team follows the main communication channels used by developers, (2) provide a common place for coordination for an ecosystem, (3) consider including both good technical and social skills in a release team, (4) aim for a diverse release team, (5) based on lack of power, lobbying and consensus based management must be followed, (6) help the release team in the coordination process with a well defined schedule, and (7) release team work is different from regular software work. Our results can help organizations build better large-scale teams and show that research focused on individual projects might miss important parts of the picture.","2017-08-30","2025-05-05 17:05:44","2025-05-05 17:05:44","","NA","","NA","8","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result. Our results suggest that there is no representative difference between their build success (they are similar in 85% of the analyzed projects), meaning that being a casual contributor is not a strong indicator for creating failing builds.

They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data. Design/methodology/approach - The methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample. Findings - The quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning. Research limitations/implications - The results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning. Practical implications - This study allows the authors to highlight two main practical contributions for OSSCs' directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables. Originality/value - This paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more “fine-grained” analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).","2017","2025-05-05 17:05:45","2025-05-05 17:05:45","","534-554","","4","30","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Library And Information Sciences; Collaboration; Open source; Open-source software; Business model; Business models; Public domain; 51321:Software Publishers; Software industry; Strategic management; Value creation; Empirical analysis; Qualitative analysis; 14.14:COMMUNICATIONS AND INFORMATION TECHNOLOGY - SOFTWARE; Accommodation; Aggregates; Business competition; Quantitative analysis; Social activism","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Economics often pictures this phenomenon as a case of signalling: individuals engage in the volunteer programming of open-source software (OSS) as a labour-market signal resulting in a wage premium. Yet, this explanation could so far not be empirically tested. This article fills this gap by estimating an upper-bound composite wage premium of voluntary OSS contributions and by separating the potential signalling effect of OSS engagement from other effects. Although some 70% of OSS contributors believe that OSS involvement benefits their careers, we find no actual labour-market premium for OSS engagement. The presence of other motives, such as fun of play or altruism, renders OSS contributions too noisy to function as a signal.","2017-03","2025-05-05 17:05:45","2025-05-05 17:05:45","","1379-1394","","14","49","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; peer production; Business And Economics; Open-source software; Noise; Engagement; open-source software; Public domain; Volunteering; D01; J24; J31; Signalling; voluntary work; wage formation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, I will demonstrate how open source software may be used for achieving similar purposes. However, the interplay between local copyright law, public procurement law and open source community norms creates many issues relating to the legal status and ownership in modified software, based on open source. This is especially so in the case of so-called copyleft open source licenses, where a collision occurs between copyright, as an absolute right enforceable against the world, and the copyleft provisions of license agreements, which may be treated as “rights in personam” enforceable only against the licensee. The exclusive right to derivative software as an independent object of copyright, may come into conflict with restrictions inherited from incoming copyleft licenses. This paper provides an overview and analysis of such problems faced by Russian software developers, attempting to comply with Russian import substitution provisions, by using open source components. Although it is based on Russian law, it may be applicable to other jurisdictions, since general aspects of copyright law and its interaction with private international law and contract law drive it. The paper concludes that the developer of software, containing code licensed under GEL or other copyleft provisions, receives full exclusive right to the derivative software and can commercialize it as he sees appropriate, subject only to possible claims of breach of contract rather than copyright infringement. This opens wide perspectives for using open source components regardless of the type of license used as bricks for building a de-globalized economy and society based on principles of information sovereignty.

On the one side, we argue that developers will actively affect knowledge sharing in terms of participative motivation, social network and organisational culture. On the other hand, users may also affect the knowledge sharing when considering innovation willingness and capacity.

The authors investigate network structure as a causal factor for both new project initiation within a group (representing group innovation) as well as new developers joining existing projects within a group (representing group growth).

There is a trade-off between the effects of inter-group structural hole and inter-group coupling on group innovation.The authors test these four hypotheses using data from OSS. Developers contributing to project tasks in groups other than their own can explore novel ideas for new project creation, because they can benefit from sharing knowledge, whereas developers contributing to project tasks inside their own group exploit ideas to improve those existing projects with better inside-group search possibility; and this demands more developers to join those group projects.","2017","2025-05-05 17:05:46","2025-05-05 17:05:46","","7–18","","1","15","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Innovation; open source software; Hypotheses; Open-source software; Product development; Volunteers; Innovations; cluster management; network management; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS influences the way organizations develop, acquire, use and commercialize software. SECOs have emerged as a paradigm to understand dynamics and heterogeneity in collaborative software development. For this reason, SECOs appear as a valid instrument to analyze OSS systems. However, there are few studies that blend both topics together. Objective: The purpose of this study is to evaluate the current state of the art in OSS ecosystems (OS-SECOs) research, specifically: (a) what the most relevant definitions related to OSSECOs are; (b) what the particularities of this type of SECO are; and (c) how the knowledge about OSSECO is represented. Method: We conducted a systematic mapping following recommended practices. We applied automatic and manual searches on different sources and used a rigorous method to elicit the keywords from the research questions and selection criteria to retrieve the final papers. As a result, 82 papers were selected and evaluated. Threats to validity were identified and mitigated whenever possible. Results: The analysis allowed us to answer the research questions. Most notably, we did the following: (a) identified 64 terms related to the OSSECO and arranged them into a taxonomy; (b) built a genealogical tree to understand the genesis of the OSSECO term from related definitions; (c) analyzed the available definitions of SECO in the context of OSS; and (d) classified the existing modelling and analysis techniques of OSSECOs. Conclusion: As a summary of the systematic mapping, we conclude that existing research on several topics related to OSSECOs is still scarce (e.g., modelling and analysis techniques, quality models, standard definitions, etc.). This situation calls for further investigation efforts on how organizations and OSS communities actually understand OSSECOs. (C) 2017 Elsevier B.V.

Quantitative analysis of AOSLO images typically requires manual grading, which is time consuming, and subjective; thus, automated algorithms are highly desirable. Previously developed automated methods are often reliant on ad hoc rules that may not be transferable between different imaging modalities or retinal locations. In this work, we present a convolutional neural network (CNN) based method for cone detection that learns features of interest directly from training data. This cone-identifying algorithm was trained and validated on separate data sets of confocal and split detector AOSLO images with results showing performance that closely mimics the gold standard manual process. Further, without any need for algorithmic modifications for a specific AOSLO imaging system, our fully-automated multi-modality CNN-based cone detection method resulted in comparable results to previous automatic cone segmentation methods which utilized ad hoc rules for different applications. We have made free open-source software for the proposed method and the corresponding training and testing datasets available online.","2017-07-26","2025-05-05 17:05:46","2025-05-05 17:05:46","","NA","","NA","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The defect density of such projects is often required to be predicted for the purpose to ensure quality standards. Static metrics for defect density prediction require extraction of abstract information from the code. Repository metrics, on the other hand, are easy to extract from the repository data sets. In this paper, an analysis has been performed over repository metrics of open source software. Further, defect density is being predicted using these metrics individually and jointly. Sixty two open source software are considered for analysis using Simple and Multiple Linear Regression methods as statistical procedures.

For that to happen an accurate, robust and reliable method for structural monitoring is needed. GNSS with its advanced augmentation techniques can give a positioning accuracy in order of millimetres at its best. Such a higher order of accuracy can be used for precise structural deformation monitoring. Apart from that GNSS gives us loathsome advantages like all weather, around the clock and global coverage. GNSS doesn't need line of sight as it was needed in previous techniques between its stations. Due to these benefits we are using GNSS technology for structural deformation monitoring. GNSS also has some drawbacks like the positioning accuracy is dependent up on number of available satellites, geometry of satellites, multipath and receiver noise. Un-affordable price of precise GNSS receivers also makes it tougher. The data used in the thesis is the one used for structural deformation monitoring with the help of base stations and the rovers using the real time kinematic RTK positioning logged at ICON Tower Karachi, Pakistan a high-rise building. RTKLIB a free software is used for analysis of logged data by applying stand-alone, differential code and differential carrier phase (RTK) positioning techniques. For our post processing GPS data analysis we had used three rovers at three corners of building story under monitoring with common reference station. One by one on each of the sets we have RTK in RTKPOST GUI application of RTKLIB. For this analysis we have made three cases of comparison between individual RTK results of rover pairs and concluded deformation in a small chunk of time (3600 epochs) one hour data.","2017","2025-05-05 17:05:47","2025-05-05 17:05:47","","NA","","NA","NA","","","","International Conference on Aerospace Science and Engineering","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-5386-3601-5 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Fusing and organizing many different ideas, opinions, and interpretations into a coherent and acceptable plan or project evaluation is challenging. This is especially true when seeking contributions from a large number of participants, especially when not all can participate in group discussions, or when some prefer to contribute their perspectives anonymously. One of the major breakthroughs in the area of evaluation and program planning has been the use of graphical tools to represent the brainstorming process. This provides a quantitative framework for organizing ideas and general concepts into simple-to-interpret graphs. We developed a new, open-source concept mapping software called R-CMap, which is implemented in R. This software provides a graphical user interface to guide users through the analytical process of concept mapping. The R-CMap software allows users to generate a variety of plots, including cluster maps, point rating and cluster rating maps, as well as pattern matching and go-zone plots. Additionally, R-CMap is capable of generating detailed reports that contain useful statistical summaries of the data. The plots and reports can be embedded in Microsoft Office tools such as Word and PowerPoint, where users may manually adjust various plot and table features to achieve the best visual results in their presentations and official reports. The graphical user interface of R-CMap allows users to define cluster names, `change the number of clusters, select rating variables for relevant plots, and importantly, select subsets of respondents by demographic criteria. The latter is particularly useful to project managers in order to identify different patterns of preferences by subpopulations. R-CMap is user-friendly, and does not require any programming experience. However, proficient R users can add to its functionality by directly accessing built-in functions in R and sharing new features with the concept mapping community. (C) 2016 Elsevier Ltd.

This interest stems not only from cost savings, but also from benefits concerning reproducibility and collaboration. Technical challenges hamper practical reproducibility, especially when multiple software packages are required to conduct an analysis. In this study, we use containerization to package a GEOBIA workflow in a well-defined FOSS environment. We explore the approach using two software stacks to perform an exemplary analysis detecting destruction of buildings in bi-temporal images of a conflict area. The analysis combines feature extraction techniques with segmentation and object-based analysis to detect changes using automatically-defined local reference values and to distinguish disappeared buildings from non-target structures. The resulting workflow is published as FOSS comprising both the model and data in a ready to use Docker image and a user interface for interaction with the containerized workflow. The presented solution advances GEOBIA in the following aspects: higher transparency of methodology; easier reuse and adaption of workflows; better transferability between operating systems; complete description of the software environment; and easy application of workflows by image analysis experts and non-experts. As a result, it promotes not only the reproducibility of GEOBIA, but also its practical adoption.","2017-03","2025-05-05 17:05:48","2025-05-05 17:05:48","","NA","","3","9","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we assess open source software projects, with respect to their reusability, i.e., the easiness to adapt them in a new system. By taking into account that domain-specific reuse is more beneficial than domain-agnostic; we focus this study on identifying the application domains that contain the most reusable software projects. To achieve this goal, we compared the reusability of approximately 600 OSS projects from ten application domains through a case study. The results of the study suggested that in every aspect of reusability, there are different dominant application domains. However, Science and Engineering Applications and Software Development Tools, have proven to be the ones that are the most reuse-friendly.

These software packages are now routinely used by researchers and clinicians, and have contributed to important breakthroughs for the understanding of brain anatomy and function. However, no software package exists to process mpMRI data of the spinal cord. Despite the numerous clinical needs for such advanced mpMRI protocols (multiple sclerosis, spinal cord injury, cervical spondylotic myelopathy, etc.), researchers have been developing specific tools that, while necessary, do not provide an integrative framework that is compatible with most usages and that is capable of reaching the community at large. This hinders cross-validation and the possibility to perform multi-center studies. In this study we introduce the Spinal Cord Toolbox (SCT), a comprehensive software dedicated to the processing of spinal cord MRI data. SCT builds on previously-validated methods and includes state-of-the-art MM templates and atlases of the spinal cord, algorithms to segment and register new data to the templates, and motion correction methods for diffusion and functional time series. SCT is tailored towards standardization and automation of the processing pipeline, versatility, modularity, and it follows guidelines of software development and distribution. Preliminary applications of SCT cover a variety of studies, from cross-sectional area measures in large databases of patients, to the precise quantification of mpMRI metrics in specific spinal pathways. We anticipate that SCT will bring together the spinal cord neuroimaging community by establishing standard templates and analysis procedures.","2017-01-15","2025-05-05 17:05:49","2025-05-05 17:05:49","","24-43","","A","145","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there are a limited number of evidences related to the application of CBL in the field of Software Engineering (SE). In this paper, we present an open source web application called SEABED (Software Engineering Case-Based Learning Database). The feature set supported by SEABED comprises Case Submission, Case Collection, Case Search, Case Review, and Case Evolution. SEABED aims to develop and evolve a rich repository of SE cases that might become a basis for enabling the students, instructors, practitioners, and experts to enhance their SE knowledge in an effective way. Further, we present our approach to build a vibrant SE case-based learning community that triggers enough activity around SEABED, required for the platform to reach a critical and wider mass. We communicated with several SE educators around the world and received positive responses on SEABED. In order to investigate the effectiveness of the CBL methodology followed by SEABED, we conducted an experimental study at an Institute of National Importance in India. We present the empirical analysis results of this study and explore the impact of CBL on students' learning abilities.","2017","2025-05-05 17:05:49","2025-05-05 17:05:49","","426-431","","NA","NA","","","","Proceedings International Computer Software and Applications Conference","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 978-1-5386-0367-3 Place: NA Publisher: NA","","","","NA","","Reisman, S.; Ahamed, S.

However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma, allowing for early diagnosis and intervention. We have developed Specvis, a free and open-source application written in Java programming language that can run on any personal computer to meet this requirement (http://www. specvis. pl/). Specvis was tested on glaucomatous, retinitis pigmentosa and stroke patients and the results were compared to results using the Medmont M700 Automated Static Perimeter. The application was also tested for inter-test intrapersonal variability. The results from both validation studies indicated low inter-test intrapersonal variability, and suitable reliability for a fast and simple assessment of visual field impairment. Specvis easily identifies visual field areas of zero sensitivity and allows for evaluation of its levels throughout the visual field. Thus, Specvis is a new, reliable application that can be successfully used for visual field examination and can fill the gap between confrontation and perimetry tests. The main advantages of Specvis over existing methods are its availability (free), affordability (runs on any personal computer), and reliability (comparable to high-cost solutions).","2017-10-13","2025-05-05 17:05:49","2025-05-05 17:05:49","","NA","","10","12","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The social and technical activities of developers evolve together, and as they link to each other they get organized in a network of changing socio-technical connections. Traces of those activities, or behaviors, are typically visible to all, in project repositories and through communication between them. Thus, in principle it may be possible to study those traces to tell which of the observable socio-technical behaviors of developers in these projects are responsible for the forming of persistent links between them. It may also be possible to tell the extent to which links participate in the spread of potential behavioral influences. Since OSS projects change in both social and technical activity over time, static approaches, that either ignore time or simplify it to a few slices, are frequently inadequate to study these networks. On the other hand, ad-hoc dynamic approaches are often only loosely supported by theory and can yield misleading findings. Here we adapt the stochastic actor-oriented models from social network analysis. These models enable the study of the interplay between behavior, influence and network architecture, for dynamic networks, in a statistically sound way. We apply the stochastic actor-oriented models in case studies of two Apache Software Foundation projects, and study code ownership and developer productivity as behaviors. For those, we find evidence of significant social selection effects (homophily) in both projects, but in different directions. However, we find no evidence for the spread (social influence) of either code ownership or developer productivity behaviors through the networks.","2017-02","2025-05-05 17:05:49","2025-05-05 17:05:49","","407-435","","1","22","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Especially in the higher education sector, IT is playing a vital role in the advancement of teaching and learning practices. Most of the educational organizations have already adopted smart learning environment by upgrading their infrastructure and with proper capacity building among staff members. But in the education sector, sustainability of technology is always being a challenge. To develop learning materials, many institutions have already started using free and open source software (FOSS) tools. FOSS gives freedom to the developer with the provision of various customization options as per the requirements of the class or subject. Moreover, in the longer run, free and open source software could be considered as the best option in education for e-learning implementation, for sustainability. There are many tools which are available for e-learning resource development. Some of them are available online and some are available as an installer for the various platform. In order to adapt ICT in education, especially in non-IT specialization, the faculty members need the training to learn and implement these tools in their classes. But there are many tools, which are specially designed for educators with basic knowledge of computers. Educators can plan their sessions, based on content, duration as well as the level of the subject and the students. This research paper will highlight various aspects of the implementation of FOSS, in education by using such easy-to-implement tools and techniques. This would provide general guidelines for the development of various e-learning solutions for technology-enhanced teaching and learning practices in higher education.","2017","2025-05-05 17:05:49","2025-05-05 17:05:49","","1075-1079","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: Int Org Ctr Acad Res ISBN: 978-605-82433-1-6 Place: YUNUS EMRE CAD AKASYA SK NO 22, UGUR MUMCU, ISTANBUL, KARTAL 00000,\n TURKEY Publisher: INT ORGANIZATION CENTER ACAD RESEARCH","","","","open source software; Free; E-learning; Multimedia in education; Sustainability in education; \n Interactive educational tools; \n Technology-enhanced learning; Enhanced teaching; learning practices","","Uslu, F.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then countless libraries across the United States have used the program to create online tutorials in order to teach a variety of information literacy skills including how to search databases, how to evaluate websites, how to create better searches, and how to search for medical information. The Guide on the Side was created by a group of University of Arizona librarians in order to replicate the hands-on experience students received when they attended a library session on how to use a research database. Librarians aimed to give students the guided instruction they received in face-to-face sessions. Sophisticated research databases are often difficult for undergraduate students to use, and they need both background knowledge and repeated practice to use a database successfully. With the Guide on the Side, students are presented with authentic tasks and are able to conduct “live” searches as they are guided through the database. Through these activities, they learn how to locate the information they need quickly. Although a valuable and easy to use software program, instructors and librarians are often at a loss for how to create tutorials that are appealing to students and that are aligned with best practices for online instruction. This paper will focus on best practices when using the Guide on the Side. These best practices have been developed by the author and are based on current educational research focused on online instruction and on usability studies conducted using the Guide on the Side. This paper discusses the development of the Guide on the Side, how to download it, and how to implement these best practices in order to create learning experiences for students that are both engaging and effective.","2017","2025-05-05 17:05:50","2025-05-05 17:05:50","","395-400","","NA","NA","","","","INTED Proceedings","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-84-617-8491-2 Place: LAURI VOLPI 6, VALENICA, BURJASSOT 46100, SPAIN Publisher: IATED-INT ASSOC TECHNOLOGY EDUCATION & DEVELOPMENT","","","","information literacy; library; online instruction; tutorials; guide on\n the side","","Chova, L.

To investigate how automated testing is performed in practice, we attempted a thorough, large-scale analysis of open source repositories. Alongside this analysis, we propose a novel approach to reuse such existing tests within projects that lack test code, hence leveraging the quality of such projects with minimal developer intervention. While such an analysis seems to be a straightforward task, we report on various practical challenges that hindered applying our proposed approach for tests' reuse.

What strategies are adopted by the sponsor to influence the organizational structure of free software communities? Two constructs are central to the study: organizational structure and sponsorship. For this research, we adopted case study methodology and three free software communities were studied. In the analysis of the results it was evidenced that sponsors influence decision making, definition of community key roles, and a formalization of norms.

Although this strategy has clear benefits, it does not place enough care in training students to face complex, non-trivial legacy software projects. To bridge this gap, novel SE courses are leveraging the rich variety of open-source software (OSS) projects to illustrate how these methodologies and concepts are applied to existing, non-trivial software systems. To better understand the benefits, challenges, and opportunities of this transition, in this paper, we interview seven SE professors that changed their academic setting to aspire students to comprehend, maintain, and evolve OSS systems as part of their SE course. We found that there are different ways to make use of OSS projects in SE courses in terms of project choice, assessment, and learning goals. Moreover, we evidence clear benefits of this approach, including improving students' social and technical skills, and helping students enhancing their resume. Also, we observed that this strategy comes with costs: the activity demands effort and time from the professor and the barrier for one getting involved with and, therefore, placing a meaningful contribution, in an OSS community is often high.","2017","2025-05-05 17:05:51","2025-05-05 17:05:51","","117-121","","NA","NA","","","","Conference on Software Engineering Education and Training","","","","","","NA","","","","","","","Backup Publisher: IEEE; Reliability Soc; Armstrong State Univ ISBN: 978-1-5386-2536-1 Place: NA Publisher: NA","","","","NA","","Washizaki, H.; Mead, N.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Having a good knowledge of molecular structure is crucial to work out polarity of compounds, intermolecular forces and their relationship with properties. In addition, it is very important to understand the inorganic systems that explain the behaviour of atoms, ions and molecules in understanding the phenomena of organic chemistry [2]. Therefore, the understanding of spatial structures is central to the discipline of chemistry. However, in textbooks molecular structures are represented as two-dimensional objects and as result, students might find difficult to switch from 2D to 3D structures or images. Using 3 dimensional models help students acquire a better understanding of molecular geometry and encourage active learning. Computer visualizations now offer an interesting possible alternative to concrete or physical models [3]. Jmol is one of the most prevalent molecular visualization tools in STEM education. It is a free open source software for interactive molecular visualization. This work describes the implementation of the Jmol visualization tool in a module on General Chemistry for Engineers during the academic year 2016-2017. The goals were three-fold. Firstly, to use the Jmol visualization application as a teaching tool for classroom demonstration. Then, to provide students with the skills to use the molecular visualization tool for their own learning process. Finally, to actively engage students with generation and manipulation of molecular models. Jmol application was used during Lectures to teach about molecular structure. Students then had to download and use the application on their own to complete several worksheets. Later on, Jmol molecular models were also used to aid student understanding of organic chemistry, including isomerism. Additional worksheets and assignments involved the use of Jmol visualization tool. The evaluation of the software implementation on the module was carried out by marking the worksheets and by a survey that was conducted among the students.","2017","2025-05-05 17:05:51","2025-05-05 17:05:51","","9355-9359","","NA","NA","","","","EDULEARN Proceedings","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-84-697-3777-4 Place: NA Publisher: NA","","","","NA","","Chova, L.

The well-being of a FOSS project depends on the turning of project newcomers into `good contributors' that is to say into individuals that substantially contribute to the project - but also that perform citizenship behaviors that protect and nurture its community. This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness.

AgHA was synthesized by a chemical precipitation method. After characterization, AgHA was mixed with Bio-Oss((R)) at three ratios: 1:1, 1:2, and 1:4 by weight. Then, Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were used to test the antibacterial activity of the mixture. Human periodontal ligament fibroblasts and rat bone marrow stromal cells were selected for cytocompatibility experiments. According to results, the peak value of the size of the AgHA was concentrated in the 100-200 nm range, and AgHA particles consisted of short rods. It was confirmed that the structure of AgHA was similar to that of standard hydroxyapatite. All three mixture ratios exhibited obvious antimicrobial properties, which increased with increasing AgHA. According to the effects on the expression of bacterial virulence genes, groups 1:1 and 1:2 both negatively affected Pg and Fn more significantly than group 1:4. Cytotoxicity experiments showed that 1:1 caused little cytotoxicity, while groups 1:2 and 1:4 exerted no significant cytotoxicity. Considering its biological compatibility and antibacterial activity, group 1:2 is the most recommended. (c) 2017 Wiley Periodicals, Inc.

This report describes a semiautomatic approach to decrease the manual reidentification error. This study evaluated the repeatability of surgical outcome measurements using the semiautomatic approach. Furthermore, a step-by-step guide is provided to enable researchers and clinicians to perform the 3D analysis by themselves. Materials and Methods: Evaluating surgical outcome consists of 2 parts. First, the scans are aligned at the anterior cranial base. Second, a semiautomatic approach is used to place 3 dental reference points at exactly the same sites of the pre-and postoperative maxilla. Because the maxilla is repositioned during surgery but otherwise unaltered, the reference points should be identical if the pre-and postoperative scans are aligned at the maxilla. Therefore, the authors propose the insertion of reference points on the preoperative scan and then repositioning a copy of the preoperative reference points relative to the postoperative scan. To align the reference points on the postoperative scan, the hard palate is used as a mutual maxillary reference structure. A reproducibility test was performed in 10 participants by analyzing the difference between repeated measurements. Results: Repeated linear measurements differed by less than 0.1 mm along all 3 axes (standard deviations, < 0.1 mm). The 2 largest differences between repeated measurements were 0.33 mm along the superoinferior axis and 0.29 along the anteroposterior axis. Repeated rotational measurements differed by less than 0.1 degrees around all 3 axes (standard deviations, <= 0.1 degrees). Conclusion: The semiautomatic approach showed excellent linear and angular repeatability. The algorithm can be implemented in the clinical evaluation of orthognathic surgical outcome and postoperative relapse.

The topic of bugs has been extensively investigated and reported in the literature. Unfortunately, the existential question of all “whether a reported bug will be fixed or not” has not received much attention. The paper presents an empirical study on four open source projects to examine the factors that influence the likelihood of a bug getting fixed or not. Overall, our study can be contextualized as a conceptual replication of a previous study on Microsoft systems from a commercial domain. The similarities and differences in terms of the design, execution, and results between the two studies are discussed. It was observed from these systems that the reputations of the reporter and assigned developer to fix it, and the number of comments on a bug have the most substantial impact on its probability to get fixed.

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.","2018-05","2025-05-05 17:05:52","2025-05-05 17:05:52","","NA","","5","10","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","QGIS; remote sensing; global warming; land surface temperature; Landsat-8; urban heat island; urbanization; \n semi-automatic classification plugin","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Users tend to be involved at the periphery of FOSS communities, suggesting new product ideas, highlighting problems with user documentation, or explaining when the product design fails to fit with the needs of their local user application domain. As an increasing number of FOSS projects employ a hybrid participation model that combines volunteer effort with paid software development effort or product support, it can be difficult for non-developer users to participate in product innovation. In colocated organizations, it is theorized that peripheral participants learn how to engage with the practices and cultural identity of a community through a sociocultural apprenticeship known as legitimate peripheral participation. But we have little literature that explores how legitimate peripheral participation is enabled in online communities.The research study presented in this article explores how participation by peripheral users in a hybrid FOSS project is afforded by participation architecture channels and community mechanisms that mediate two forms of engagement: a “cognitive apprenticeship” that introduces participants to situated domain activity, such as the community processes involved in product innovation, and a “social apprenticeship” by which participants become enculturated in the system of meanings, values, norms, and behaviors that govern community/participant identity. We identified five stages of community innovation, analyzing sociotechnical affordances of the online participation architecture that enable peripheral participants to internalize the meanings of community practice and to develop a social identity within the FOSS community. Our contribution to theory is provided by the substantive explanation of the cognitive and social translations that enable legitimate peripheral participation in online communities, mediated by sociotechnical access channels and mechanisms that afford two contrasting forms of opportunities for action: those resulting from interactions between a goal-oriented actor and the technology platform features or channels of participation, and those associated with the social structures, roles, and relationships underpinning community interactions. Neither of these is sufficient without the other. Our contribution to practice is provided by an explanation of how four distinct categories of affordance provide these cognitive and social apprenticeship benefits, allowing participation architecture designers to cater to all forms of peripheral user participation. We conclude that the technical affordances of a typical FOSS community participation architecture are insufficient to mediate peripheral participation by nontechnical users. Meaningful participation is mediated by interactions between boundary spanners who play knowledge-brokering and organizational bridging roles. The combination of technical and social affordances enables peripheral participants to acquire an interior view of community practices and social culture and in turn to introduce new ideas, new values, and new rationales to produce a generative dance of innovation that percolates through the community.","2018-12","2025-05-05 17:05:52","2025-05-05 17:05:52","","NA","","4","1","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","innovation; affordances; hybrid-FOSS community; Legitimate peripheral participation; participation architecture; user participation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The Madagascar, based on Python, is usually supposed to be better in the development of processing technologies due to its capabilities of multidimensional data analysis and reproducibility. However, this open-source software has not been widely used so far for field data processing because of complicated interfaces and data structure system. To verify the effectiveness of the Madagascar software on field data, we applied it to a typical seismic data processing flow including data loading, geometry build-up, F-K filter, predictive deconvolution, velocity analysis, normal moveout correction, stack, and migration. The field data for the test were acquired in Gunsan Basin, Yellow Sea using a streamer consisting of 480 channels and 4 arrays of air-guns. The results at all processing step are compared with those processed with Landmark's ProMAX (SeisSpace R5000) which is a commercial processing software. Madagascar shows relatively high efficiencies in data IO and management as well as reproducibility. Additionally, it shows quick and exact calculations in some automated procedures such as stacking velocity analysis. There were no remarkable differences in the results after applying the signal enhancement flows of both software. For the deeper part of the substructure image, however, the commercial software shows better results than the open-source software. This is simply because the commercial software has various flows for de-multiple and provides interactive processing environments for delicate processing works compared to Madagascar. Considering that many researchers around the world are developing various data processing algorithms for Madagascar, we can expect that the open-source software such as Madagascar can be widely used for commercial-level processing with the strength of expandability, cost effectiveness and reproducibility.","2018-08","2025-05-05 17:05:53","2025-05-05 17:05:53","","171-182","","3","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a “safety net” for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and “living” design documentation. Rapid-cycle development or “agile” methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as “executable requirements.” Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the “executable requirements” are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.","2018-06","2025-05-05 17:05:54","2025-05-05 17:05:54","","80-90","","2","6","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC","","","","agile methods; clinical decision support systems; electronic health records; software verification; software\n validation; test driven\n development","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To achieve our goal. we collected data from 21 popular, non-trivial GitHub projects, identified quasi-contributors, and analyzed their pull-requests. In addition, we conducted surveys with quasi-contributors, and project's integrators, to understand their perceptions about nonacceptance. We found 10,099 quasi-contributors about 70% of the total actual contributors that submitted 12,367 nonaccepted pull-requests. In five projects, we found more quasi-contributors than actual contributors. About one-third of the developers who took our survey disagreed with the nonacceptance, and around 30% declared the nonacceptance demotivated or prevented them from placing another pull-request. The main reasons for pull-request nonacceptance from the quasicontributors' perspective were “superseded/duplicated pull-request” and “mismatch between developer's and team's vision/opinion” A manual analysis of a representative sample of 263 pull-requests corroborated with this finding. We also found reasons related to the relationship with the community and lack of experience or commitment from the quasi-contributors.

However, the number of new vulnerabilities keeps increasing in today's OSS systems. With today's increasingly important and complex OSS, lacking software security knowledge to handle security vulnerabilities in OSS development will result in more breaches that are serious in the future. Learning software security is a difficult and challenging task since the domain is quite context specific and the real project situation is necessary to apply the security concepts within the specific system. Many OSS proponents believe that the OSS community offers significant learning opportunities from its best practices. However, studies that specifically explore security knowledge sharing and learning in OSS communities are scarce. This research is intended to fill this gap by empirically investigating factors that affect knowledge sharing and learning about software security and the relationship among them. A conceptual model is proposed that helps to conceptualize the linkage between socio-technical practices and software security learning processes in OSS communities. A questionnaire and statistical analytical techniques were employed to test hypothesized relationships in the model to gain a better understanding of this research topic.","2018-12","2025-05-05 17:05:54","2025-05-05 17:05:54","","NA","","4","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is at odds with current practice of performance testing, which predominantely focuses on long-running tests against entire systems in production-like environments. Alternatively, software microbenchmarking attempts to establish a performance baseline for small code fragments in short time. This paper investigates the quality of microbenchmark suites with a focus on suitability to deliver quick performance feedback and CI integration. We study ten open-source libraries written in Java and Go with benchmark suite sizes ranging from 16 to 983 tests, and runtimes between 11 minutes and 8.75 hours. We show that our study subjects include benchmarks with result variability of 50% or higher, indicating that not all benchmarks are useful for reliable discovery of slow-downs. We further artificially inject actual slowdowns into public API methods of the study subjects and test whether test suites are able to discover them. We introduce a performance-test quality metric called the API benchmarking score (ABS). ABS represents a benchmark suite's ability to find slowdowns among a set of defined core API methods. Resulting benchmarking scores (i.e., fraction of discovered slowdowns) vary between 10% and 100% for the study subjects. This paper's methodology and results can be used to (1) assess the quality of existing microbenchmark suites, (2) select a set of tests to be run as part of CI, and (3) suggest or generate benchmarks for currently untested parts of an API.","2018","2025-05-05 17:05:55","2025-05-05 17:05:55","","119-130","","NA","NA","","","","IEEE International Working Conference on Mining Software Repositories","","","","","","NA","","","","","","","Backup Publisher: IEEE Comp Soc; Assoc Comp Machinery; SIGSOFT; IEEE Tech Council Software\n Engn ISBN: 978-1-4503-5716-6 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","empirical study; Java; continuous integration; Go; microbenchmarking; software performance testing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, the discrete modeling framework has been proposed to study the reliability growth process of OSS systems with multiple releases. The proposed model is based upon the assumption that during up-gradation some new faults are introduced in the code in addition to the left over fault content of the previous version. To validate our model, we have chosen two successful open source projects-Mozilla and Apache for its multi release failure datasets. Graphs representing goodness of fit of the proposed model have been drawn. The parameter estimates and measures of goodness of fit criteria suggest that the proposed software reliability growth model for multi-release OSS fits the actual datasets very well. An optimal release policy has been formulated by taking into account the cost of fault removal during testing and operational phases and reliability targets pre-specified by the decision makers.

An alternative is the use of solutions based on free and/or open source software. To identify, among the available OSS-based BI tools, which is the most appropriate for implementation in public bodies, it is necessary to apply some specific model for evaluation and selection. The literature describes several generic methods for assessing and comparing OSS. In this work, we select a suitable method and derive a model for the comparison and selection of OSS-based BI tools able to meet the demands of public organizations.

Open Source Software (OSS) is considered to yield key benefits for SMEs because it is free to access, distribute and customise, peer-reviewed for reliability. However, certain drawbacks can hinder SMEs from adopting OSS such as uncertain support, need for technical skill for usage, incomplete functionality to mention a few. The broadband initiative in the Western Cape looked to enable the access of OSS online through the provision of broadband internet for organisations including SMEs. This research was aimed, through a qualitative analysis, mainly at examining the attitude of SMEs toward OSS by analysing the benefits as well as the drawbacks of using OSS. The research also analysed the effect of the broadband initiative on the attitude of SMEs toward OSS uptake. Additionally, the roles that intermediaries undertake in OSS communities for promoting the uptake of OSS in SMEs, which were investigated were decentralised school, bridging school, arterial school, communities of practice and ecosystems school. These intermediary roles were analysed to find out which role would be most significant for facilitating OSS uptake.","2018","2025-05-05 17:05:56","2025-05-05 17:05:56","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: IEEE ISBN: 978-1-5386-1001-5 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Material and MethodsSurfaces of a novel particulate bovine bone graft, Moa-Bone((R)) were compared with Bio-Oss((R)) using scanning electron microscopy. Six sheep then had maxillary sinus grafting bilaterally, covered with BioGide((R)). Grafted maxillae were harvested after 4, 6 and 12weeks. Healing was described for half of each site using resin-embedded ground sections. For the other half, paraffin-embedded sections were examined using tartrate resistant acid phosphatase staining for osteoclast activity, runt-related transcription factor2 immunohistochemistry for pre-osteoblasts and osteoblasts and proliferating cell nuclear antigen for proliferative cells. ResultsMoa-Bone((R)) had a smoother, more porous fibrous structure with minimal globular particles compared with Bio-Oss((R)). After 4weeks, woven bone formed on both grafts and the Moa-Bone((R)) particles also showed signs of resorption. After 12weeks, Moa-Bone((R)) continued to be resorbed, however Bio-Oss((R)) did not; both grafts were surrounded by maturing lamellar bone. Moa-Bone((R)) was associated with earlier evidence of runt-related transcription factor 2-positive cells. Moa-Bone((R)) but not Bio-Oss((R)) was associated with strong tartrate resistant acid phosphatase-positive osteoclasts on the graft surface within resorption lacunae at both 4 and 6weeks post-grafting. ConclusionBoth materials supported osseous healing and maturation without inflammation. Moa-Bone((R)) showed marked osteoclast activity after 4 and 6weeks and demonstrated positive attributes for grafting, if complete remodeling of the graft within the site is desired. Further optimization of Moa-Bone((R)) for maxillofacial applications is warranted.","2018-02","2025-05-05 17:05:56","2025-05-05 17:05:56","","80-90","","1","53","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The metadata about a change includes a change message to record the intention of the change. Classification of changes, based on change messages, into different change types has been explored in the past to understand the evolution of software systems from the perspective of change size and change density only. However, software evolution analysis based on change classification with a focus on change evolution patterns is still an open research problem. This study examines change messages of 106 OSS projects, as recorded in the git repository, to explore their evolutionary patterns with respect to the types of changes performed over time. An automated keyword-based classifier technique is applied to the change messages to categorize the changes into various types (corrective, adaptive, perfective, preventive, and enhancement). Cluster analysis helps to uncover distinct change patterns that each change type follows. We identify three categories of 106 projects for each change type: high activity, moderate activity, and low activity. Evolutionary behavior is different for projects of different categories. The projects with high and moderate activity receive maximum changes during 76-81 months of the project lifetime. The project attributes such as the number of committers, number of files changed, and total number of commits seem to contribute the most to the change activity of the projects. The statistical findings show that the change activity of a project is related to the number of contributors, amount of work done, and total commits of the projects irrespective of the change type. Further, we explored languages and domains of projects to correlate change types with domains and languages of the projects. The statistical analysis indicates that there is no significant and strong relation of change types with domains and languages of the 106 projects.","2018-12","2025-05-05 17:05:56","2025-05-05 17:05:56","","1105-1124","","6","12","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Only a few empirical studies investigate how the choice of components is conducted in industrial practice. This is important to understand to tailor research solutions to the needs of the industry. Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches. The non-deterministic solutions proposed for architectural group decision making appear to suit the CSO decision making in industry better.

Although social networks constructed in online environment can reduce such possibilities, it is not without limitations. One possible mechanism for learning and knowledge flow is direct watching and observation. This study investigates the impact of co-membership taking into account the alternative mechanism of watching under the setting of OSS development at GitHub. It finds that both co-membership and watching contribute positively to OSS success, and thus shows the co-existence of both experiential learning and vicarious learning for OSS development. Moreover, it finds the impact of co-membership is much stronger than watching. While the impact of co-membership may be biased in prior literature, this study confirms that co-membership is indeed an effective mechanism for constructing online social networks for knowledge flow.","2018","2025-05-05 17:05:57","2025-05-05 17:05:57","","4252-4260","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: Pacific Res Inst Informat Syst & Management; Shidler Coll Business;\n IBM; Bizgenics Fdn; Arizona Eller; AIS; Baylor Business Informat Syst;\n Int Soc Serv Innovat; St Johns Univ, Coll Profess Studies; Syracuse\n Univ, Sch Informat Stud ISBN: 978-0-9981331-1-9 Place: Dept IT Mgmt, Shidler College of Business, Univ Hawaii at Manoa 2404\n Maile Way D307, Honolulu, Hawaii, UNITED STATES Publisher: HICSS","","","","NA","","Bui, T.

Companies get involved in FLOSS projects to acquire user innovations [3, 12], to reduce costs [8, 11], to make money on complementary services [13], etc. Such intense involvement may change the nature of FLOSS development and pose critical challenges for the sustainability of the projects. For example, it has been found that a company's full control and intense involvement is associated with a decrease of volunteer inflow [13]. Sometimes a project may fail after one company pulls resources from the project [13]. This raises concerns about the domination of one company in a project. In large projects like OpenStack, there are often hundreds of companies involved in contributing code. Despite substantial researches on commercial participation, whether or not one company dominates a project and the impact of such domination has never been explicitly explored. We investigate four main projects of OpenStack, a large ecosystem that has had a tremendous impact on computing and society, to answer the following research questions: Does one company dominate the project's development (RQ1)?

This work proposes to close this gap by measuring dependency, code reuse, and knowledge flow networks in open source software. We have done preliminary work by developing suitable tools and methods that rely on public version control data to measure and comparing these networks for R language and emberjs packages. We propose ways to calculate the three networks for the entirety of public software, evaluate their accuracy, and to provide public infrastructure to build risk assessment and mitigation tools for various individual and organizational participants in open sources software.

In this paper, the aim is to analyze the impact of community dynamics on syntactic quality of commit messages of an OSS project. We first propose and validate a commit message quality model, and then use that model to analyze the OSS projects. Empirical analysis of seven OSS projects available in the Git repository shows that a small group of contributors active at the same time in a project leads to high syntactic quality contributions.

Objective: The aim of this study is to bridge the gap between OSS adoption models, especially with the aim of supporting users in evaluating the OSS they are planning to select. Method: To reach this aim, we studied the processes and the information considered by the major OSS assessment models. Then we carried out a case study to identify which information can be automatically retrieved from the main OSS platforms, namely GitHub, SonarCloud, and StackExchange. Finally, we characterized the maturity of the projects available on these three platforms. Results: Projects available on the three platforms are commonly old, stable, and mature ones. Moreover, thanks to the API provided, we were able to extract most of the information not commonly accessible from the main website. Conclusions: Our results confirm that it is possible to develop a decision support system based on these three platforms, and that is also possible to evaluate both the quality and the maturity of the projects available there.","2018-12","2025-05-05 17:05:58","2025-05-05 17:05:58","","104-108","","NA","104","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The evaluation and comparison of more than one examination is time-consuming and prone to create errors. Using the free software environment R we developed a solution to average the data of multiple examinations and to allow a comparison of different patient groups. Methods: Data of single mfERG recordings as exported in .csv format from a RETIport 21 system (version 7/03, Roland Consult) or manually compiled .csv files are the basis for the calculations. The R software extracts response densities and implicit times of N1 and P1 for the sum response, each ring eccentricity, and each single hexagon. Averages can be calculated for as many subjects as needed. The mentioned parameters can then be compared to another group of patients or healthy subjects. Application of the software is illustrated by comparing 11 patients with chloroquine maculopathy to a control group of 7 healthy subjects. Results: The software scripts display response density and implicit time 3D plots of each examination as well as of the group averages. Differences of the group averages are presented as 3D and grayscale 2D plots. Both groups are compared using the t-test with Bonferroni correction. The group comparison is furthermore illustrated by the average waveforms and by boxplots of each eccentricity. Conclusions: This software solution on the basis of the programming language R facilitates the clinical and scientific use of the mfERG and aids in interpretation and analysis.","2018-01","2025-05-05 17:05:59","2025-05-05 17:05:59","","87-93","","1","28","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The flux variance similarity (FVS) partitioning method is based on flux variance similarity relationships and correlation analyses of high-frequency eddy covariance data (Scanlon and Sahu, 2008; Scanlon and Kustas, 2010, 2012). The FVS method is relatively complex computationally, and that complexity has likely been an impediment to greater use and testing of the procedure.

In this study, we present an economic model to study how software licensing attributes affect a software originator's decisions, aiming to provide policy makers with insights into how welfare-improving, open-source outcomes can be incentivized. We show that when a competing contributor is apt at reaping the benefits of software development investment, a less restrictive open source license (e.g., Berkeley Software Distribution, or BSD style) can improve welfare. On the other hand, when the originator is better at leveraging investment and service costs are high, a more restrictive license (e.g., General Public License, or GPL style) can be best for social welfare even when a contributor can cost-efficiently develop the software.","2018-03","2025-05-05 17:06:00","2025-05-05 17:06:00","","186-205","","1","29","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The physicochemical properties of MCs are investigated by Raman spectra, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and nitrogen adsorption-desorption isotherms. Results show that MCs derived from moxa floss of different storage years by two facile approaches possess different morphologies: MCs by hydrothermal carbonization (denoted as MC-1, MC-2 and MC-3) exhibit porous nanosheet structures, the highest specific surface area is about 1788.6 m(2) g(-1), and the largest total pore volumes is around 0.8170 cm(3) g(-1), while MCs by direct pyrolysis (denoted as MC-4, MC-5 and MC-6) have basically blocky and rod-like morphologies, the highest specific surface area is about 1628.0 m(2) g(-1), and the largest total pore volume is around 0.7058 cm(3) g(-1). However, despite the different morphologies, all MCs possess a similar hierarchical porous structure, numerous heteroatom groups and good electrical conductivity. Therefore, these low-cost, biomass-derived porous carbons with promising capacitive performance are used for supercapacitors application with high performance, for example, the as-assembled supercapacitor based on MC-5 exhibits a high specific capacitance of 288.3 F g(-1) at 0.25 A g(-1), an excellent rate performance of 243.5 F g(-1) even at 30 A g(-1) with 84.5% capacitance retention of its initial specific capacitance, and an outstanding long-term cycling stability with 98.7% capacitance retention after 10 000 cycles at 5 A g(-1). Furthermore, the maximum energy density for these supercapacitors with an aqueous electrolyte in a two-electrode system is about 10.0 W h kg(-1) at a power density of 70.3 W kg(-1). Therefore, this work opens up a whole new field for the applications of moxa floss and this novel concept of moxa floss use is an extremely promising strategy for developing high-performance carbons with porous structures and heteroatom-doping from renewable sources.","2018","2025-05-05 17:06:00","2025-05-05 17:06:00","","16433-16443","","30","8","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While there exists a large knowledge base of software maintainability, this knowledge is rarely used in open source software due to the large number of developers and inefficiency in identifying quality issues. To effectively utilize the current knowledge base in practice requires a deeper understanding of how problems associated with the different qualities arise and change over time. In this paper, we sample over 6000 real bugs found from several Mozilla products to examine how maintainability is expressed with subgroups of repairability and modifiability. Furthermore, we manually study how these qualities evolve as the products mature, what the root causes of the bugs are for each quality and the impact and dependency of each quality. Our results inform which areas should be focused on to ensure maintainability at different stages of the development and maintenance process.","2018","2025-05-05 17:06:01","2025-05-05 17:06:01","","226-237","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Reliabil Soc ISBN: 978-1-5386-7757-5 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","software maintainability; software maintainability ontology; software quality measurement; software\n quality","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I trace the learning trajectories of two participants from high school until they enter the professional workforce and beyond. I argue that FLOSS participation represents an ideal networked form of learning as it provides both socio-cognitive support for short term activities and also socio-temporal support for long term participation and learning. It is a unique form of apprenticeship that exists concurrently with formal educational experiences but unlike traditional apprenticeship experiences it succeeds by spanning different spatialities - place/space and technology mix and temporal scales.","2018","2025-05-05 17:06:01","2025-05-05 17:06:01","","NA","","NA","NA","","","","OpenSym '18","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-4503-5936-8 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","FLOSS; learning across scales; situated cognition","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Richard Stallman, founder of the Free software movement, has argued that creating and distributing non-Free software is always a moral injustice. In this essay, I try to identify the ethical foundations of Stallmanism. I identify three major trends in Stallman’s thinking—libertarian, utilitarian, and communitarian—and I argue that none is sufficient to justify the radical claim that distributing non-Free software is always wrong (unless we accept extremely demanding ethical standards that Stallman himself does not consistently endorse). I recommend thinking of Stallmanism as an attempt to optimize the satisfaction of a number of core values, including freedom, cooperation, and happiness, and I stress the importance of connecting the Free software movement to other political struggles against oppression.","2018-09","2025-05-05 17:06:01","2025-05-05 17:06:01","","437–453","","3","31","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Sociology; Ethics; Software; Free software; Freeware; Source code; Communitarianism; Computer ethics; Libertarianism; Stallman; Utilitarianism","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Some others have investigated knowledge management among open-source-software (OSS) developers and discussed factors influencing knowledge transfer within development teams (e.g. Joshi and Sarker, 2006). In the domain of open source software (OSS) communities, more companies are now attempting to establish relationships to benefit from these potential value-creating communities; and project managers could in fact target different goals within software development teams including knowledge transfer within and between teams. We step forward to distinguish knowledge transfer within groups as opposed to knowledge transfer between groups; where relevant projects are bundled into separate strongly intra-connected groups. In knowledge management literature there is a trade-off between sparse network structures (Burt, 2000, 2002) versus dense network structures (Walker et al., 1997; Coleman, 1988). It is argued that the former facilitates the diffusion and generation of ideas among groups, while the latter affects the implementation of idea within each dense group. To our best knowledge, there has been no study to investigate the relationship between dense and sparse network structures. We propose that knowledge transfer within dense groups has a positive influence on knowledge transfer between sparse groups, in that intragroup density, group size, developers centrality and betweenness could impact intergroup coupling. To prove our hypothesis, we use a complex network of open source software (OSS) as the domain of interest, where developers represent nodes and two developers contributing to a project task represent a network tie. Developers contributing to tasks in groups other than their own can explore novel ideas via sharing knowledge, whereas developers contributing to tasks inside groups exploit ideas to improve those projects. We investigate the idea both analytically and empirically within 4 months, 8 months and 1 year lagged time, and finally show that intragroup density has a positive whereas developers' centrality has a negative influence on intergroup coupling.","2018-02","2025-05-05 17:06:01","2025-05-05 17:06:01","","167-174","","1","38","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Community; Knowledge transfer; Open-source software; Knowledge management; Knowledge sharing; Information sharing; Centrality; Software development; Coupling; Public domain; 23721:Land Subdivision; Developers; Social Sciences: Comprehensive Works; Betweenness; Source code; Sparse network","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The convenient sampling technique was used to collect data. The data collected were interpreted using descriptive statistics and independent t-test. Findings - The results reveal that Chinese research and academics libraries depend mostly upon commercial software and place a great deal of trust on locally produced free software. This situation may be caused due to the lack of professional knowledge in OSS and lack of appropriate technical expertise. Although there were a sufficient number of librarians who have shown interest in OSS, they did not enthusiastically agree to implement it in their libraries. Furthermore, the interviews highlighted the professionals' opinion that most librarians are reluctant to adopt OSS due to the risk factor, lack of professional expertise, insufficient interest of the Chinese Government and lack of professional training. Originality/value - The findings are useful for the Chinese LIS community, software developers, technology administrators and library administrators.

However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm's practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems. (C) 2017 The Authors.

To more effectively manage and progress the projects, it is important and beneficial to rank the programmers and thus, predict the developer candidates. In this work, we propose to combine machine learning techniques with existing complex network node ranking algorithms to improve the prediction results. Specifically, we have made the following contributions: (1), we have designed a novel machine learning-based classifier with significantly improved prediction performance; (2), we have constructed and tested various networks built based on the programmer email communication information; and (3), we have used real-world project data to compare different techniques and validate our methods. Experimental results demonstrate that our technique reduces the error rate by 25% compared with the second best. Moreover, we discover that the KK nearest neighbor (KNN)-based machine learning algorithm and non-directional temporal network with a time window of 1-3 months give the best prediction results.","2018-06","2025-05-05 17:06:02","2025-05-05 17:06:02","","845-868","","6","28","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD","","","","machine learning; Open source software; complex network; ranking\n algorithm","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This makes it difficult to conserve experimental metadata and track the analysis performed. It also complicates certain experimental approaches such as online analysis. To address this, we developed NeuroMatic, an open-source software toolkit that performs data acquisition (episodic, continuous and triggered recordings), data analysis (spike rasters, spontaneous event detection, curve fitting, stationarity) and simulations (stochastic synaptic transmission, synaptic short-term plasticity, integrate-and-fire and Hodgkin-Huxley-like single-compartment models). The merging of a wide range of tools into a single package facilitates a more integrated style of research, from the development of online analysis functions during data acquisition, to the simulation of synaptic conductance trains during dynamic-clamp experiments. Moreover, NeuroMatic has the advantage of working within Igor Pro, a platform-independent environment that includes an extensive library of built-in functions, a history window for reviewing the user's workflow and the ability to produce publication-quality graphics. Since its original release, NeuroMatic has been used in a wide range of scientific studies and its user base has grown considerably.

An Analysis of Mentors' and Newcomers' Barriers in OSS Projects","NA","","0925-9724","10.1007/s10606-018-9310-8","NA","Newcomers' seamless onboarding is important for open collaboration communities, particularly those that leverage outsiders' contributions to remain sustainable. Nevertheless, previous work shows that OSS newcomers often face several barriers to contribute, which lead them to lose motivation and even give up on contributing. A well-known way to help newcomers overcome initial contribution barriers is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in OSS projects. Studying mentors' perspectives on the barriers that newcomers face play a vital role in improving onboarding processes; yet, OSS mentors face their own barriers, which hinder the effectiveness of the strategy. Since little is known about the barriers mentors face, in this paper, we investigate the barriers that affect mentors and their newcomer mentees. We interviewed mentors from OSS projects and qualitatively analyzed their answers. We found 44 barriers: 19 that affect mentors; and 34 that affect newcomers (9 affect both newcomers and mentors). Interestingly, most of the barriers we identified (66%) have a social nature. Additionally, we identified 10 strategies that mentors indicated to potentially alleviate some of the barriers. Since gender-related challenges emerged in our analysis, we conducted nine follow-up structured interviews to further explore this perspective. The contributions of this paper include: identifying the barriers mentors face; bringing the unique perspective of mentors on barriers faced by newcomers; unveiling strategies that can be used by mentors to support newcomers; and investigating gender-specific challenges in OSS mentorship. Mentors, newcomers, online communities, and educators can leverage this knowledge to foster new contributors to OSS projects.","2018-12","2025-05-05 17:06:03","2025-05-05 17:06:03","","679-714","","3-6, SI","27","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER","","","","Onboarding; Open source software; Challenges; Coach; Difficulties; Joining process; Newbie; Newcomer; Novice; Obstacles; Tutor; \n Mentor","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The cornerstone of the proposed approach lies in the introduction of a fictive (or virtual) chemical species, the physical characteristics of which are set to recover some essential properties of combustion and flames. Special emphasis is presently placed on the capability of such a global kinetic scheme to recover three parameters that are recognized as the most influential in terms of turbulence chemistry interactions and turbulent premixed combustion regimes. These parameters are (i) the burnt gases temperature T-b, which settles the value of the thermal expansion factor tau = (T-b - T-u)/T-u, (ii) the propagation velocity delta(0)(L), which is mandatory to reproduce the flame dynamics, and (iii) the laminar premixed flame thickness delta(0)(L). In practice, the thermochemical properties of the fictive species (hereafter denoted by A(Phi)) are set to account for the impact of dissociation effects and partial oxidation of the fuel, i.e., presence of species other than H2O and CO2 in the burnt gases, which allows to recover a satisfactory estimate of T-b. The value of the pre-exponential factor associated to the single-step Arrhenius law is also optimized to reproduce the laminar flame propagation velocity. Finally, the transport characteristics are determined to recover a satisfactory estimate of the thermal flame thickness. The method is general in its principles and quite easy to implement. It is applicable to any couple of fuel and oxidizer. Attention is focused on the application of the method to any stoichiometry but it is also shown that the influence of both pressure and fresh reactants temperature can be recovered. The performance of the resulting optimized single step (OSS) chemistry models are assessed through a direct comparison with detailed chemistry results. Computations of one-dimensional laminar flames are performed with the OSS model using the cantera software for a wide range of pressure levels, fresh reactant temperatures, and equivalence ratios. Obtained results do show that the flame propagation velocity is correctly reproduced for the whole range of parameters, with a maximum value recovered in the vicinity of stoichiometry, a decrease towards rich conditions, and a satisfactory pressure dependence. Burnt gases temperature as well as thermal flame thickness values are also in excellent agreement with those issued from the reference detailed kinetics models. The OSS model is then used to perform direct numerical simulation (DNS) computations of flame kernel growths in both laminar and turbulent conditions. The comparison of obtained OSS results with detailed chemistry computations further confirms the relevance and performance of the proposed methodology. (C) 2018 The Combustion Institute.

The dynamic morphological evolution under a large/small overpotential is studied in two dimensions, revealing important dendrite growth/stable deposition patterns. The corresponding temporal spatial distributions of ion concentration, overpotential, and driving force are studied, which demonstrate an intimate, dynamic competition between ion transport and electrochemical reactions, resulting in vastly different growth patterns. On the basis of the understanding from this model, we propose a “compositionally graded electrolyte” with higher local ion concentration as a way to potentially suppress dendrite formation. Given the importance of morphological evolution for lithium metal electrodes, widespread applications of phase-field models have been limited in part due to in-house or proprietary software.

An open source application QPhenoMetrics - implemented in QGIS software that estimates vegetation phenology metrics is presented, using Earth Observation Systems (EOS) based time-series of Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) as proxies for phenology. QPhenoMetrics is characterized by freely-usable and updatable code, acceptance of satellite images or text formats, time-series analysis toolbox allowing the selection of region of interest with statistical quality assessment for Vegetation Indices (VI), and estimation of ensemble metrics. The application is structured in three components: (i) input data; (ii) pre-processing of the VI time-series and several fitting methods and (iii) computation of the phenological metrics. QPhenoMetrics produces a plot with the VI time-series and corresponding phenology metrics, and a spreadsheet is created with a list of NDVI or EVI values estimated using the selected fitting method. To evaluate the application, two main Portuguese crops, vineyards and maize, and MOD13 data from MODIS sensor during 2011-2012 were considered. QPhenoMetrics was validated with vineyard phenology observations (2007-2011). A comparative analysis with software products TimeSat and Spirits was also performed. It was concluded that QPhenoMetrics can be very useful for common users to extract phenology information for 16 daily MODIS data in HDF format, text files with NDVI/EVI data and ASCII files, through a simple and intuitive graphic interface. Furthermore, the user can evaluate the quality assessment of VI of the images used. QPhenoMetrics is an effective open source tool that in addition to being free, is readily modifiable by user according to the study requirements.","2018-05","2025-05-05 17:06:04","2025-05-05 17:06:04","","82-94","","NA","148","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These assays measure diffusion by monitoring the return of fluorescence in bleached regions (FRAP), or the dissipation of fluorescence from photoconverted regions (iFRAP). However, current FRAP/iFRAP analysis methods suffer from simplified assumptions about sample geometry, bleaching/photo-conversion inhomogeneities, and the underlying reaction-diffusion kinetics. To address these shortcomings, we developed the software PyFRAP, which fits numerical simulations of three-dimensional models to FRAP/iFRAP data and accounts for bleaching/photoconversion inhomogeneities. Using PyFRAP we determined the diffusivities of fluorescent molecules spanning two orders of magnitude in molecular weight. We measured the tortuous effects that cell-like obstacles exert on effective diffusivity and show that reaction kinetics can be accounted for by model selection. These applications demonstrate the utility of PyFRAP, which can be widely adapted as a new extensible standard for FRAP analysis.","2018-04-20","2025-05-05 17:06:04","2025-05-05 17:06:04","","NA","","NA","9","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The main reason for this is the potential that it provides for reducing development effort and increasing the end-product quality. At the same time, Open-Source Software (OSS) repositories are nowadays flourishing and can facilitate the reuse process, through the provision of a variety of software artifacts. However, up-to-date OSS reuse processes have mostly been opportunistic, leading to not fully capitalizing existing reuse potentials. In this study we propose a process (namely REACT) for improving planned OSS reuse practices, i.e., we define the activities that a software engineer can perform to reuse OSS artifacts. To illustrate the applicability of REACT, we provide an example, in which a mobile application is developed based upon the reuse of OSS artifacts. To validate the proposed process we compared the effort required to develop the application with and without adapting REACT process. Our preliminary results suggest that REACT may reduce up to 50% the effort required to build an application from scratch.","2018","2025-05-05 17:06:05","2025-05-05 17:06:05","","251-254","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-1-5386-5841-3 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Drawing on signaling theory, this manuscript explores how third-party assessment can influence a developers' decision to join an OSS project. In order to test it, vignette survey study was conducted manipulating reputation, development experience, and a number of current OSS projects of existing developers in the OSS project. The findings suggest that all three signals have a positive influence on developer's decision to join the OSS project. This suggests that projects seeking to expand the number of contributing developers should consider offering information about its “star developers”.","2018","2025-05-05 17:06:05","2025-05-05 17:06:05","","NA","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: 978-0-9966831-6-6 Place: P.O.

Second, most pipelines are implemented in special hardware, resulting in limited flexibility of implemented processing steps on such platforms. With SUPRA, we propose an open-source pipeline for fully software-defined ultrasound processing for real-time applications to alleviate these problems. Covering all steps from beamforming to output of B-mode images, SUPRA can help improve the reproducibility of results and make modifications to the image acquisition mode accessible to the research community. We evaluate the pipeline qualitatively, quantitatively, and regarding its run time. The pipeline shows image quality comparable to a clinical system and backed by point spread function measurements a comparable resolution. Including all processing stages of a usual ultrasound pipeline, the run-time analysis shows that it can be executed in 2D and 3D on consumer GPUs in real time. Our software ultrasound pipeline opens up the research in image acquisition. Given access to ultrasound data from early stages (raw channel data, radiofrequency data), it simplifies the development in imaging. Furthermore, it tackles the reproducibility of research results, as code can be shared easily and even be executed without dedicated ultrasound hardware.","2018-06","2025-05-05 17:06:05","2025-05-05 17:06:05","","759-767","","6, SI","13","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Increasingly complex simulations are used to assess similarities and differences between the two models' components. The simulations presented here are forced by ocean currents from a Finite Volume Community Ocean Model (FVCOM) implementation that has excellent skill in representing tidal motion, and with observed wind data that compensates for a coarse vertical ocean model resolution. The comprehensive comparison between GNOME and BLOSOM presented here, should aid modelers in interpreting their results. Beyond many similarities, aspects where both models are distinct are highlighted. Some suggestions for improvement are included, e.g., the inclusion of temporal interpolation of the forcing fields (BLOSOM) or the inclusion of a deflection angle option when parameterizing wind-driven processes (GNOME). Overall, GNOME and BLOSOM perform similarly, and are found to be complementary oil spill models. This paper also sheds light on what drove the historical Point Wells spill, and serves the additional purpose of being a learning resource for those interested in oil spill modeling. The increasingly complex approach used for the comparison is also used, in parallel, to illustrate the approach an oil spill modeler would typically follow when trying to hindcast or forecast an oil spill, including detailed technical information on basic aspects, like choosing a computational time step. We discuss our successful hindcast of the 2003 Point Wells oil spill that, to our knowledge, had remained unexplained. The oil spill models' solutions are compared to the historical Point Wells' oil trajectory, in time and space, as determined from overflight information. Our hindcast broadly replicates the correct locations at the correct times, using accurate tide and wind forcing. While the choice of wind coefficient we use is unconventional, a simplified analytic model supported by observations, suggests that it is justified under this study's circumstances. We highlight some of the key oceanographic findings as they may relate to other oil spills, and to the regional oceanography of the Salish Sea, including recommendations for future studies.","2018-09","2025-05-05 17:06:05","2025-05-05 17:06:05","","NA","","3","6","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","BLOSOM; Foss Barge; GNOME; hindcast; model comparison; ocean trajectory; oil spill model; Salish Sea; windage; Point\n Wells","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For example, end-user reviews help to identify missing features or inform developers about incorrect or unexpected software behavior. We believe that analyzing end-user reviews and utilizing analysis tools are a crucial step towards understanding the complete picture of the quality of a software product, as well as towards reasoning about the evolution history of it. In this paper, we investigate whether both methods correlate with one another. In other words, we explore if there exists a relationship between user satisfaction and the application's internal quality characteristics. To conduct our research, we analyze a total of 46 actual releases of three Android open source software (OSS) applications on the Google Play Store. For each release, we employ multiple static analysis tools to assess several aspects of the application's software quality. We retrieve and manually analyze the complete reviews after each release of each application from its store page, totaling 1004 reviews.

This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success. We also show that when development environment difference is moderate, the impact of role diversity is the most positive. We present the implications of these findings for theory and practice.","2018-09","2025-05-05 17:06:05","2025-05-05 17:06:05","","237-256","","3","27","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER","","","","Success; Diversity; Open source projects; Connectedness; Development difference; Participant\n difference","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Often this takes the form of company employees devoting their time to contribute code to the efforts of projects in these communities. Ideology has traditionally served to motivate, coordinate, and guide volunteer contributions to OSS communities. As employees represent an increasing proportion of the participants in OSS communities, the role of OSS ideology in guiding their commitment and code contributions is unknown. In this research, we argue that OSS ideology misfit has important implications for companies and the OSS communities to which their employees contribute, since their engagement in such communities is not necessarily voluntary. We conceptualize two different types of misfit: OSS ideology under-fit, whereby an employee embraces an OSS ideology more than their coworkers or OSS community do, and OSS ideology over-fit, whereby an employee perceives that their coworkers or OSS community embrace the OSS ideology more strongly than the employee does. To develop a set of hypotheses about the implications of these two types of misfit for employee commitment to the company and commitment to the OSS community, we draw on self-determination theory. We test the hypotheses in a field study of 186 employees who participate in an OSS community. We find that OSS ideology under-fit impacts the company and the community in the same way: it decreases employee commitment to the company and commitment to the OSS community. In contrast, we find that OSS ideology over-fit increases commitment to the company but decreases commitment to the OSS community. Finally, we find that employees' commitment to their company reinforces the impact of their commitment to the OSS community in driving ongoing code contributions.

In her novels she searched for a view of life that would give modern man a sense of purpose, dignity and ethical direction. On reading Eliot's novels with the knowledge of her intellectual development, one must ask how this earnest agnostic could treat traditional religion so sympathetically, why she made the religious experience the subject of her creative work, and what moral truth she found religion to embody. It was the philosophy of the German anthropologist Ludwig Feuerbach, whose book The Essence of Christianity she translated in 1854, in combination with her own earlier experiences as a Christian, which led Eliot to her understanding of the subjective reality embodied in Christianity. `With the ideas of Feuerbach,' Eliot wrote, `I everywhere agree' (Haight, 1954-55, p.153). My paper attempts to show how the influence of Feuerbach achieves complexity and vitality in Eliot's novel The Mill on the Floss and how Eliot establishes her faith in firm and lasting relations, which could be attained through the adjustment of the individual to the community. This adjustment comes as a corollary to the protagonist's realization of the principles that promote love, respect, tolerance and sacrifice for others.","2018","2025-05-05 17:06:07","2025-05-05 17:06:07","","10-18","","3","10","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software documentation for these libraries is crucial in helping programmers/analysts know what libraries are available and how to use them. Yet documentation for open source software libraries is widely considered low-quality. This article is a collaboration between CSCW researchers and contributors to data analytics OSS libraries, based on ethnographic fieldwork and qualitative interviews. We examine several issues around the formats, practices, and challenges around documentation in these largely volunteer-based projects. There are many different kinds and formats of documentation that exist around such libraries, which play a variety of educational, promotional, and organizational roles. The work behind documentation is similarly multifaceted, including writing, reviewing, maintaining, and organizing documentation. Different aspects of documentation work require contributors to have different sets of skills and overcome various social and technical barriers. Finally, most of our interviewees do not report high levels of intrinsic enjoyment for doing documentation work (compared to writing code). Their motivation is affected by personal and project-specific factors, such as the perceived level of credit for doing documentation work versus more `technical' tasks like adding new features or fixing bugs. In studying documentation work for data analytics OSS libraries, we gain a new window into the changing practices of data-intensive research, as well as help practitioners better understand how to support this often invisible and infrastructural work in their projects.","2018-12","2025-05-05 17:06:07","2025-05-05 17:06:07","","767-802","","3-6, SI","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Knowledge can be shared among individuals, groups, and organizations. A free software community is a type of community of practice arranged around a specific free software, where the knowledge shared is complex and the knowledge sharing processes have scarcely been studied. This investigation aims to identify the profiles of knowledge sharing processes in free software communities and examine how 6 motivations for sharing knowledge in free software communities are associated with each of the clusters. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters were identified: Sporadic Sharer; Collector; Donator; and Constant Sharer. With the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators and Collectors. These results confirm the view of free software communities as communities of practice and highlight the importance of knowledge sharing in free software development cycle. The results reveal the importance of the Constant Sharer profile, which has the highest rates of donation and collection and is also the profile in which all the motivations appear with the highest values, indicating its key role in the functioning of free software communities.","2018-09","2025-05-05 17:06:07","2025-05-05 17:06:07","","143-152","","3","25","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Motivation; Software; Knowledge sharing; Free software; Software development; Freeware; Life cycle engineering; Communities of practice; Cluster analysis; Community of practice; Intellectual capital; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Companies must govern their FLOSS use to avoid potential risks to their intellectual property resulting from the use of FLOSS components. A particular challenge is license compliance. To manage the complexity of license compliance, companies should use tools and well-defined processes to perform these tasks time and cost efficiently. This paper investigates and presents common industry requirements for FLOSS governance tools, followed by an evaluation of the suggested requirements by matching them with the features of existing tools. We chose 10 industry leading companies through polar theoretical sampling and interviewed their FLOSS governance experts to derive a theory of industry needs and requirements for tooling. We then analyzed the features of a governance tools sample and used this analysis to evaluate two categories of our theory: FLOSS license scanning and FLOSS in product bills of materials. The result is a list of FLOSS governance requirements based on our qualitative study of the industry, evaluated using the existing governance tool features. For higher practical relevance, we cast our theory as a requirements specification for FLOSS governance tools.","2018","2025-05-05 17:06:08","2025-05-05 17:06:08","","151-167","","NA","525","","","","IFIP Advances in Information and Communication Technology","","","","","","NA","","","","","","","Backup Publisher: Harokopio Univ; IFIP WG 2 13 ISBN: 978-3-319-92375-8; 978-3-319-92374-1 Place: NA Publisher: NA","","","","NA","","Stamelos, I.; GonzalezBarahona, J.

Bioinformatics, a core component of omics research, is one of the disciplines that first employed Free/Libre Open Source Software (FLOSS), and thus provided a fertile ground for its further development. Understanding the use and characteristics of FLOSS deployed in the omics field is valuable for future innovation strategies, policy and funding priorities. We conducted a bibliometric, longitudinal study of the use of FLOSS in sepsis omics research from 2011 to 2015 in the United States, EU-28 and China. Because sepsis is an interdisciplinary field at the intersection of multiple omics technologies and medical specialties, it was chosen as a model innovation ecosystem for this empirical analysis, which used publicly available data. Despite development of and competition from proprietary commercial software, scholars in omics continue to employ FLOSS routinely, and independent of the type of omics technology they work with. The number of articles using FLOSS increased significantly over time in the EU-28, as opposed to the United States and China (R=0.96, p=0.004). Furthermore, in an era where sharing of knowledge is being strongly advocated and promoted by public agencies and social institutions, we discuss possible correlations between the use of FLOSS and various funding sources in omics research. These observations and analyses provide new insights into the use of FLOSS in sepsis omics research across three (supra)national regions. Further benchmarking studies are warranted for FLOSS trends in other omics fields and geographical settings. These could, in time, lead to the development of new composite innovation and technology use metrics in omics systems sciences and bioinformatics communities.","2018-05","2025-05-05 17:06:08","2025-05-05 17:06:08","","365-372","","5","22","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The model has an outer layer exchanging radiation and heat with the environment and a stack of layers beyond modifying the thermal behavior. The orientation of the layer is defined by the normal vector of the surface. The innermost layer is at a constant or variable temperature called core temperature. All the layers have heat capacity and thermal conductivity. The outer layers properties are color (visible), emissivity (IR), coefficients of free and forced convection, and a factor for latent heat. The environmental parameters are air temperature, wind speed, relative humidity, irradiation of the sun, and thermal radiation of the sky and ground. The properties of the model (7 parameters) are fitted to minimize the difference between the prediction and a time series of measured temperatures. The size of the time series is one or more days with 288 values per day (5 minute resolution). The model is useable for very different objects like backgrounds (meadow, forest, rocks, sand, or bricks) or parts of objects like vehicles. The STANDCAM is a decoy of a vehicle and is used to constitute a thermal signature and is not classified. The STANDCAM has a complex CAD-Model with thousands of triangular facets that had to be simplified for the thermal simulation. The CAD model was available through WTD 52, an agency of the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw). Groups of elements of the model facing in the same direction and behaving similarly were cut out and grouped in distinct objects. The calculation of the temperature of the objects is based on measured environmental data and the model parameters are fitted on measured radiation temperatures of the objects and backgrounds. For the visualization the object is surrounded by a world texture. For the radiation temperature of the environment and the ground under the object measured air and meadow temperatures were used. The temperature is coded as a color from a palette (here we use a grey palette) and is updated regularly throughout the calculation of the scene for the selected view and is stored as a texture bitmap. The animation of the temperature textures is directly performed by BLENDER. The result of the visualization is available as movie that is watchable in real time or time lapse.","2018","2025-05-05 17:06:08","2025-05-05 17:06:08","","NA","","NA","10794","","","","Proceedings of SPIE","","","","","","NA","","","","","","","Backup Publisher: SPIE ISBN: 978-1-5106-2172-5 Place: NA Publisher: NA","","","","NA","","Stein, K.

The success of open source software is known to be attributable to a massive number of contributors engaging in the development process. However, an efficient open source software project is not guaranteed simply by active participation by many; a coordination mechanism is needed to seamlessly manage the multi-party collaboration. On this basis, this study aimed to examine the internal regulatory processes based on Git and GitHub, which serve as such a mechanism, and redefine the efficiency of open source software projects to fully reflect them. For this purpose, a two-stage data envelopment analysis was used to measure the project efficiency reflecting the internal processes. Moreover, this study considered the Kruskal-Wallis test and Tobit regression analysis to examine the effects of the participation by many on an open source software project based on the newly defined efficiency. Results show that a simple increase in contributors can be poisonous in terms of the efficiency of open source software projects.","2018-09","2025-05-05 17:06:09","2025-05-05 17:06:09","","NA","","9","10","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","GitHub; collaboration; Git; open source software projects; efficiency; data\n envelopment analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Several instructors already make use of contribution to OSS as part of the teaching and evaluation process in their courses. However, little is known about how students perceive the approach of contributing to OSS projects in the context of a Software Engineering course. This paper aims to uncover challenges and benefits from the students' perspective. To achieve this, we conducted14 semi-structured interviews with students who attended to this kind of courses in five different Brazilian universities, resulting in findings not so well known. For example, we noticed that, although instructors point to the projects that students are required to contribute to, students (and the project community) are involved in the process of choosing projects and tasks (issues). We also identified that students' contributions vary in terms of number of lines added and removed in commits, as well as the use of different programming languages.","2018","2025-05-05 17:06:09","2025-05-05 17:06:09","","260-269","","NA","NA","","","","SBES '18","","","","","","NA","","","","","","","Backup Publisher: Faber Castell; B2W Digital; UOL; CeMEAI; Google; Univ Sao Paulo, Inst\n Ciencias Matematicas Computacao; Univ Fed Sao Carlos; Inst Fed Sao\n Paulo; IBM; Monitora ISBN: 978-1-4503-6503-1 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","comunidades; engenharia de software; software livre; educa\ç\ão","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Software, however, is increasingly developed in open source software (OSS) forms which have several unique characteristics. In this study, we approach OSS RE as a sociotechnical, distributed cognitive process where distributed actors “compute” requirements- i.e., transform requirements-related knowledge into forms that foster a shared understanding of what the software is going to do and how it can be implemented. Such computation takes place through social sharing of knowledge and the use of heterogeneous artifacts. To illustrate the value of this approach, we conduct a case study of a popular OSS project, Rubinius-a runtime environment for the Ruby programming language-and identify ways in which cognitive workload associated with RE becomes distributed socially, structurally, and temporally across actors and artifacts. We generalize our observations into an analytic framework of OSS RE, which delineates three stages of requirements computation: excavation, instantiation, and testing-in-the-wild. We show how the distributed, dynamic, and heterogeneous computational structure underlying OSS development builds an effective mechanism for managing requirements. Our study contributes to sorely needed theorizing of appropriate RE processes within highly distributed environments as it identifies and articulates several novel mechanisms that undergird cognitive processes associated with distributed forms of RE.","2018","2025-05-05 17:06:09","2025-05-05 17:06:09","","1217-1252","","12","19","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Interviews; Cognition; Information systems; Theory; Open source; Software engineering; Software; Open-source software; Knowledge; Research; Case studies; Software development; Codes; Requirements engineering; Programming languages; Agile software development; Distributed computing; Public domain; Engineering; Cognition & reasoning; Artifacts; Archives & records; Computation; Keywords; Requirements analysis; Verbal communication; Computers–Information Science And Information Theory; 51921:Libraries; Archives","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It simulates the macro- and micromixing scales, and the complete energy and population balance equations during crystal nucleation and growth. The model is based on the Reynolds-Averaged-Navier-Stokes equation, coupled with a three-environment presumed probability density function model, and the spatially varying population balance equation semidiscretized using a high resolution finite-volume method. openCrys is implemented in C++ object oriented programming language using the open-source CFD package OpenFOAM. The software is used to compare the performance of dual impinging jet, coaxial, and radial crystallizers. It is shown that improving the micromixing does not necessarily result in a narrower crystal size distribution when temperature effects are taken into account. The complex interplay of crystallizer kinetics and momentum, mass, and heat transfer makes the selection of the best mixer for a particular application to be nonobvious, which motivates the development and application of high-fidelity multiscale simulations for the design of antisolvent crystallizers.","2018-08-29","2025-05-05 17:06:09","2025-05-05 17:06:09","","11702-11711","","34","57","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Conflicting agendas may create miss-alignment with the firm's internal requirements strategy. In communities with meritocratic governance or with aspects thereof, a firm has the opportunity to affect the RE process in line with their own agenda by gaining influence through active and symbiotic engagements. Objective: The focus of this study has been to identify what aspects that firms should consider when they assess their need of influencing the RE process in an OSS community, as well as what engagement practices that should be considered in order to gain this influence. Method: Using a design science approach, 21 interviews with 18 industry professionals from 12 different software-intensive firms were conducted to explore, design and validate an artifact for the problem context. Results: A Community Strategy Framework (CSF) is presented to help firms create community strategies that describe if and why they need influence on the RE process in a specific (meritocratic) OSS community, and how the firm could gain it. The framework consists of aspects and engagement practices. The aspects help determine how important an OSS project and its community is from business and technical perspectives. A community perspective is used when considering the feasibility and potential in gaining influence. The engagement practices are intended as a tool-box for how a firm can engage with a community in order to build influence needed. Conclusion: It is concluded from interview-based validation that the proposed CSF may provide support for firms in creating and tailoring community strategies and help them to focus resources on communities that matter and gain the influence needed on their respective RE processes.","2019-08","2025-05-05 17:06:09","2025-05-05 17:06:09","","102-114","","NA","112","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The data were obtained both from the National Vulnerability Database (NVD), and from project-specific web resources, which we monitor on a continuous basis.From that data, we extracted a dataset that maps 624 publicly disclosed vulnerabilities affecting 205 distinct open-source Java projects, used in SAP products or internal tools, onto the 1282 commits that fix them.

Moreover, these scripts allow to complement the dataset with additional instances that are not security fixes (which is useful, for example, in machine learning applications).Our dataset has been successfully used to train classifiers that could automatically identify security-relevant commits in code repositories.

Consequently, OSS project members must rely on subjective inferences based on fragile and incomplete information for trust-related decision making. We propose an automated approach to assist a developer in identifying the trustworthiness of another developer. Our two-fold approach, first, computes direct trust between developer pairs who have interacted previously by analyzing their interactions via natural language processing. Second, we infer indirect trust between developers who have not interacted previously by constructing a community-wide developer network and propagating trust in the network. A large-scale evaluation of our approach on a GitHub dataset consisting of 24,315 developers shows that contributions from trusted developers are more likely to be accepted to a project compared to contributions from developers who are distrusted or lacking trust from project members. Further, we develop a pull request classifier that exploits trust metrics to effectively predict the likelihood of a pull request being accepted to a project, demonstrating the practical utility of our approach.","2019-12-30","2025-05-05 17:06:10","2025-05-05 17:06:10","","NA","","12","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These new paradigms, and especially Orchestration, will have a great impact on the Legacy Network Management Systems and the Operations Support System (OSS). We present a state of the art review of the main architecture approaches in the SDN standardization forums and discuss the place of the Orchestration in these different architectures. Then we focus on the Orchestration at the application layer and show how, together with SDN and Network Function Virtualization, they influence the Operation and Business Support Systems of next-generation network management. Finally, we analyze the roles and functions of this Orchestrator with regard to upper management, as well as the several open challenges in this domain.","2019-02","2025-05-05 17:06:10","2025-05-05 17:06:10","","17-31","","NA","62","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While working on OSS projects contributors acquire project related individualistic knowledge and gain experience and skills, which often remains unshared with others and is usually lost once contributors leave a project. All software development organisations face the problem of knowledge loss as employees leave, but this situation is exasperated in OSS projects where most contributors are volunteers with largely unpredictable engagement durations. Contributor turnover is inevitable due to the transient nature of OSS project workforces causing knowledge loss, which threatens the overall sustainability of OSS projects and impacts negatively on software quality and contributor productivity. Objective: The objective of this work is to deeply and systematically investigate the phenomenon of knowledge loss due to contributor turnover in OSS projects as presented in the state-of-the-art literature and to synthesise the information presented on the topic. Furthermore, based on the learning arising from our investigation it is our intention to identify mechanisms to reduce the overall effects of knowledge loss in OSS projects. Methodology: We use the snowballing methodology to identify the relevant literature on knowledge loss due to contributor turnover in OSS projects. This robust methodology for a literature review includes research question, search strategy, inclusion, exclusion, quality criteria, and data synthesis. The search strategy, and inclusion, exclusions and quality criteria are applied as a part of snowballing procedure. Snowballing is considered an efficient and reliable way to conduct a systematic literature review, providing a robust alternative to mechanically searching individual databases for given topics. Result: Knowledge sharing in OSS projects is abundant but there is no evidence of a formal strategy or practice to manage knowledge. Due to the dynamic and diverse nature of OSS projects, knowledge management is considered a challenging task and there is a need for a proactive mechanism to share knowledge in the OSS community for knowledge to be reused in the future by the OSS project contributors. From the collection of papers found using snowballing, we consolidated various themes on knowledge loss due to contributor turnover in OSS projects and identified 11 impacts due to knowledge loss in OSS projects, and 10 mitigations to manage with knowledge loss in OSS projects. Conclusion: In this paper, we propose future research directions to investigate integration of proactive knowledge retention practices with the existing OSS practices to reduce the current knowledge loss problem. We suggest that there is insufficient attention paid to KM in general in OSS, in particular there would appear to an absence of proactive measures to reduce the potential impact of knowledge loss. We also propose the need for a KM evaluation metric in OSS projects, similar to the ones that evaluate health of online communities, which should help to inform potential consumers of the OSS of the KM status on a project, something that is not existent today.","2019-06","2025-05-05 17:06:10","2025-05-05 17:06:10","","104","","NA","46","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Open source; Software; Open-source software; Strategy; Knowledge management; Methodology; Project management; Software development; Software quality; Systematic review; Public domain; Software Projects; Investigations; Social Sciences: Comprehensive Works; Literature reviews; Geographical distribution; Search methods; Snowballing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, there is a lack of studies in literature that shed light into the evaluation of OSS by organizations. In this article, a method to evaluate reliability and maintainability of OSS by using both code-based and community-based aspects is proposed through the synthesis of existing studies in literature. To perform code-based evaluation, some internal attributes of the most recent quality model, ISO/IEC 25010, are selected and object-oriented C&K metrics are employed in an attempt to measure these attributes. To perform community-based evaluation, metrics derived from historical data such as e-mailing lists, problem reports, frequently asked questions, and etc. are utilized to identify and satisfy information needs as conformant to ISO/IEC 15939 standard for software measurement process. The two-dimensional method was used in selection of the Java build tools written in Java, and the results obtained by applying the proposed method and the results obtained by using OSMM and OpenBRR which are common methods in the literature were compared. According to the evaluation and comparison results, the results obtained with the existing models confirm each other and the results obtained with the proposed method.","2019","2025-05-05 17:06:11","2025-05-05 17:06:11","","1807-1829","","4","34","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The OSS community has some special characteristics (such as worldwide geographical distribution of both users and developers and missing resources) which are an obstacle to the direct adoption of many usability techniques as specified in the human-computer interaction (HCI) field. Objective: The aim of this research is to adapt and evaluate the feasibility of applying four usability techniques: user profiles, personas, direct observation and post-test information to four OSS projects from the viewpoint of the development team. Method: The applied research method was a multiple case study of the following OSS projects: Quite Universal Circuit Simulator, PSeInt, FreeMind and OpenOffice Writer. Results: We formalized the application procedure of each of the adapted usability techniques. We found that either there were no procedures for adopting usability techniques in OSS or they were not fully systematized. Additionally, we identified the adverse conditions that are an obstacle to their adoption in OSS and propose the special adaptations required to overcome the obstacles. To avoid some of the adverse conditions, we created web artefacts (online survey, wiki and forum) that are very popular in the OSS field. Conclusion: It is necessary to adapt usability techniques for application in OSS projects considering their idiosyncrasy. Additionally, we found that there are obstacles (for example, number of participant users, biased information provided by developers) to the application of the techniques. Despite these obstacles, it is feasible to apply the adapted techniques in OSS projects.","2019-03","2025-05-05 17:06:11","2025-05-05 17:06:11","","48-64","","NA","107","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is an open-source tool distributed under LGPL license, written in Java and based on the Chemistry Development Kit. Ambit-GCM provides an environment for creating models of molecular properties using additive schemes of zero, first or second orders. Ambit-GCM supports a set of local atomic attributes used for dynamic configuration of desired atom descriptions, which are applied to define fragments of different sizes. All defined groups are exhaustively generated for each molecule from a training set of compounds and combined to form the basic set of GCM fragments. Additionally, Ambit-GCM users can define correction factors via custom SMARTS notations or add externally calculated molecular descriptors. A molecular property model is obtained as a sum over all found groups by multiplying each group or correction factor frequency to its corresponding contribution. Multiple linear regression analysis (MLRA) is used for group contributions calculation. Ambit-GCM performs full statistical characterization of the obtained MLRA models via various validation techniques: external tests validation, cross validation, y-scrambling, etc. The software can be optionally used only for molecule fragmentation combined with an external statistical modelling package for further processing.

To mitigate this research gap, in this empirical study, we explore the current security culture in the OSS development phenomenon using a survey instrument with six evaluation dimensions: attitude, behavior, competency, subjective norms, governance, and communication.

Bead-based multiplexed bioassays have many technical advantages, including near solution-phase kinetics, small sample volume requirements, many within-assay replicates to reduce measurement error, and, for some bead materials, the ability to synthesize analytes directly on beads via solid-phase synthesis. To allow bead-based multiplexing, analytes can be synthesized on spectrally encoded beads with a 1:1 linkage between analyte identity and embedded codes. Bead-bound analyte libraries can then be pooled and incubated with a fluorescently-labeled macromolecule of interest, allowing downstream quantification of interactions between the macromolecule and all analytes simultaneously via imaging alone. Extracting quantitative binding data from these images poses several computational image processing challenges, requiring the ability to identify all beads in each image, quantify bound fluorescent material associated with each bead, and determine their embedded spectral code to reveal analyte identities. Here, we present a novel open-source Python software package (the mrbles analysis package) that provides the necessary tools to: (1) find encoded beads in a bright-field microscopy image; (2) quantify bound fluorescent material associated with bead perimeters; (3) identify embedded ratiometric spectral codes within beads; and (4) return data aggregated by embedded code and for each individual bead. We demonstrate the utility of this package by applying it towards analyzing data generated via multiplexed measurement of calcineurin protein binding to MRBLEs (Microspheres with Ratiometric Barcode Lanthanide Encoding) containing known and mutant binding peptide motifs. We anticipate that this flexible package should be applicable to a wide variety of assays, including simple bead or droplet finding analysis, quantification of binding to non-encoded beads, and analysis of multiplexed assays that use ratiometric, spectrally encoded beads.","2019-03-22","2025-05-05 17:06:14","2025-05-05 17:06:14","","NA","","3","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is known that for the unidirectional composites the most significant distortion of the structure of the host material takes place when the optical fiber is embedded perpendicular to the direction of the reinforcement of the composite material layers. However, the internal structure of the composites with woven layer reinforcement scheme is significantly different. And the embedding of such a foreign object as an optical fiber can cause a basically other, as compared to unidirectional composites, change in the internal structure. Cross-sectional studies were performed using an optical microscope. The analysis of cross-sections of PCM samples was carried out with the aim of studying the changes in the structure of the layered composite with woven fabric reinforcement due to the embedding of the fiber-optic sensors. A comparison of the obtained images showed that the microstructure of the studied samples is better seen on polished surfaces. In the absence of polishing on a number of samples, the optical fiber is not visually noticeable or poorly distinguishable. Analysis of the obtained images showed that there is an insignificant distortion of the internal structure of the material in the area with embedded optical fiber without the formation of a resin pocket for all studied GFRP samples.

However, to strive as a new kind of organization, open source must provide production gains, which in turn should be measurable. The open source movement is particularly interesting to study for this reason. Here, we confront and discuss two contrasting views, which were reported in the literature recently. On the one hand, Sornette et al. (2014) uncovered a superlinear production mechanism, which quantifies Aristotle adage: “the whole is more than the sum of its parts”. On the other hand, Scholtes et al. (2016) found opposite results, and referred to Maximilien Ringelmann, a French agricultural engineer (1861-1931), who discovered the tendency for individual members of a group to become increasingly less productive as the size of their group increases (Ringelmann, 1913). Since Ringelmann, the topic of collective intelligence has interested numbers of researchers in social sciences and social psychology (Woolley et al., 2010), as well as practitioners in management aiming at improving the performance of their team (Woolley et al., 2015). In most research and practice case studies, the Ringelmann effect has been found to hold, while, in contrast, the superlinear effect found by Sornette et al. is novel and may challenge common wisdom (Sornette et al., 2014). Here, we compare these two theories, weigh their strengths and weaknesses, and discuss how they have been tested with empirical data. We find that they may not contradict each other as much as was claimed by Scholtes et al. (2016). (C) 2019 Elsevier B.V.

However, mobile application developers are often left unaware of these flaws. The App Security Improvement Program (ASIP) is a commendable effort by Google to notify application developers of these flaws, but recent work has shown that many developers do not act on this information. Our work addresses vulnerable mobile applications through automatic binary patching from source patches provided by the OSS maintainers and without involving the developers. We propose novel techniques to overcome difficult challenges like patching feasibility analysis, source-code-to-binary-code matching, and in-memory patching.

To detect such vulnerabilities, finding OSS reuses in COTS software has become imperative. While scalable to tens of thousands of OSS projects, existing binary-to-source matching approaches are severely imprecise in analyzing COTS software products, since they support only a limited number of code features, compute matching scores only approximately in measuring OSS reuses, and neglect the code structures in OSS projects. We introduce a novel binary-to-source matching approach, called B2SFINDER1, to address these limitations. First of all, B2SFINDER can reason about seven kinds of code features that are traceable in both binary and source code. In order to compute matching scores precisely, B2SFINDER employs a weighted feature matching algorithm that combines three matching methods (for dealing with different code features) with two importance-weighting methods (for computing the weight of an instance of a code feature in a given COTS software application based on its specificity and occurrence frequency). Finally, B2SFINDER identifies different types of code reuses based on matching scores and code structures of OSS projects. We have implemented B2SFINDER using an optimized data structure. We have evaluated B2SFINDER using 21991 binaries from 1000 popular COTS software products and 2189 candidate OSS projects. Our experimental results show that B2SFINDER is not only precise but also scalable. Compared with the state of the art, B2SFINDER has successfully found up to 2.15x as many reuse cases in 53.85 seconds per binary file on average. We also discuss how B2SFINDER can be leveraged in detecting OSS reuse vulnerabilities in practice.","2019","2025-05-05 17:06:17","2025-05-05 17:06:17","","1038-1049","","NA","NA","","","","ASE '19","","","","","","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Comp Soc Tech Council\n Software Engn; ACM Special Interest Grp Artificial Intelligence; ACM\n Special Interest Grp Software Engn ISBN: 978-1-7281-2508-4 Place: 1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES Publisher: ASSOC COMPUTING MACHINERY","","","","OSS; Code Reuse; Code Feature; COTS Software; One-Day Vulnerability; \n Binary-to-Source Matching","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We empirically validate the model with a large dataset from 2017 GitHub Open Source Survey that includes over 5,500 randomly selected OSS developers. Results indicate that short-term and/or tangible motivations (carrots) and long-term, value-based factors (rainbows) influence OSS developers' contribution likelihood.

During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS. These results suggest that an inter-family succession of Betaproteobacteria occurred in response to colonization by mosses, followed by plants.","2019-09-25","2025-05-05 17:06:21","2025-05-05 17:06:21","","268-277","","3","34","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: C/O DR.

Internal communication within an organization was reported to cause broken links in the community, duplication of work, and political tensions.

With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person-environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity. We discuss the implications of our findings for research and practice.","2019-09","2025-05-05 17:06:24","2025-05-05 17:06:24","","951+","","3","43","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Uncertainty; Computers; Collaboration; Open source; Software; Open-source software; Regression analysis; Social networks; Commitment; Public domain; Developer; Impact fees; Congruence; Polynomials","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Appropriate plaque control is therefore important. Dental floss is one instrument used to control plaque. The influence of guardians is an important factor in whether children use dental floss regularly. However, the use of dental floss among school-age children and the relationship between use and family background has yet to be examined. Aim: In this study, we conducted a questionnaire survey to examine rates of dental floss use and other related factors among elementary school children and their guardians. Methods: Surveys were sent to 298 guardians of children in grades 1-6 at an elementary school in Japan and 283 valid responses were received. Statistical analyses were carried out, with child's use of dental floss as a dependent variable and grade, sex, guardian assistance with child's tooth brushing, frequency of child's dental check-ups, and guardian's use of dental floss as independent variables. Results: The results revealed that 18.4% of children used dental floss compared with 52.7% of guardians, suggesting that the rate of usage among children is much lower than that among guardians. Logistic regression analysis further revealed that guardian's use of dental floss was significantly related to dental floss use among children. Conclusion: The guardian's use of dental floss was associated with dental floss use among their children in this group of Japanese elementary school. (C) 2019 Japanese Society of Pediatric Dentistry.

Currently women represent less than 24% of the computing workforce and that number is declining. On the other hand, the ratios of women in Open Source Software (OSS) projects are even lower. Aims: The primary objective of this study is to determine the level of gender diversity among popular OSS projects and identify the presence of gender biases that may discourage females' participation. Method: On this goal, we mined the code review repositories of ten popular OSS projects. We used a semi-automated approach followed by a manual validation to identify the genders of the active contributors. Results: Our results suggest that lack of gender diversity remains an ongoing issue among all the ten projects as each of the projects had less than 10% female developers. However, many of the projects also suffer from lack of inclusion of females to leadership positions. Although none of the projects suggest significant differences between male and female developers in terms of productivity based on three different measures, data from three out of the ten projects indicate technical biases against female developers with lower code acceptance rates as well as delayed feedback during code reviews. However, biases against females are not universal as majority of the projects do not discriminate against females. The two projects with the least ratios of female contributors as core developers showed the most biases against females. Conclusion: Based on our findings, we conclude that promoting and mentoring females to leadership positions may be an effective solution to foster gender diversity.","2019","2025-05-05 17:06:28","2025-05-05 17:06:28","","295-305","","NA","NA","","","","International Symposium on Empirical Software Engineering and\n Measurement","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; Brazilian Comp Soc; CESAR\n Sch; State Pernambuco Fdn Sci & Technol; Natl Council Sci & Technol\n Dev, Brazilian Minist Sci, Technol, Innovat, & Commun ISBN: 978-1-7281-2968-6 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Result: We found that commercial firms participating in community-initiated OSS projects collaborate in various ways across the organizational boundaries. While most of firms contribute little, a small number of firms that are very active and account for large proportions of contributions. We proposed a conceptual model to explain for coopetition among software firms in OSS projects. The model shows two aspects of coopetition can be managed at the same time based on firm gatekeepers.

This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.","2019-09","2025-05-05 17:06:29","2025-05-05 17:06:29","","764-786","","3","30","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 5521 RESEARCH PARK DR, SUITE 200, CATONSVILLE, MD 21228 USA Publisher: INFORMS","","","","collaboration; motivation; econometrics; virtual teams; open-source software; information systems (IS) development; superposition; project\n success; task\n structure","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Trees in urban parks can play an important role in mitigating runoff and delivering other ecosystem services. Park managers, E-NGOs, citizen scientists and others are increasingly called upon to evaluate the possible consequences of changes in park management such as, e.g., tree removal. Here, we present an unorthodox approach to hydrological modelling and its potential use in local policy making regarding urban greenery. The approach consists of a minimalist field campaign to characterize vegetation and soil moisture status combined with a novel model calibration using freely available data and software. During modelling, we were able to obtain coefficients of determination (R-2) of 0.66 and 0.73 for probe-measured and simulated soil moisture under tree stand and park lawn land covers respectively. The results demonstrated that tree cover had a significant positive effect on the hydrological regime of the locality through interception, transpiration and effects on soil moisture. Simulations suggested that tree cover was twice as effective at mitigating runoff than park lawn and almost seven times better than impervious surfaces. In the case of a potential replacement of tree vegetation in favour of park lawn or impervious surfaces an increase in runoff of 14% and 81% respectively could be expected. The main conclusion drawn from our study was that such an approach can be a very useful tool for supporting local decision-making processes as it offers a freely available, cheap and relatively easy-to-use way to describe the hydrological consequences of landcover change (e.g., tree removal) with sufficient accuracy.

This cross-sectional study was conducted with a sample of 402 preschool children aged 1-5 years, from Santa Cruz do Sul, a Southern city in Brazil. Mothers answered questions about environmental, demographic, and socioeconomic characteristics. Behavior variables as use of dental floss (study outcome) and dental attendance were also evaluated. Poisson regression analysis with robust variance through a hierarchical approach was used to investigate the association of explanatory variables for use of dental floss. Prevalence ratio (PR) and 95% confidence intervals (95%CI) were estimated. The mean sample age was 3.32 years (standard deviation [SD] 1.10). Of the included children, 291 (73.12%) did not use dental floss. The environmental model indicated that children who attended daycare (PR 2.53; 95%CI 1.39-4.60) and those whose parents were members of volunteer networks (RP 1.58; 95%CI 1.02-2.46) were more likely to use dental floss. Children from families with higher income (PR 1.55; 95%CI 1.07-2.24) and maternal schooling (PR 2.21; 95%CI 1.31-3.74) presented a higher prevalence of dental floss use. Older children and those who attended dental services were also related to higher dental floss use. Our findings suggest that children who live in a supporting environment and those with a higher socioeconomic status are more likely to use dental floss.","2019","2025-05-05 17:06:33","2025-05-05 17:06:33","","NA","","NA","33","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

ESE (endoscopic submucosal excavation) is widely used for the treatment of digestive diseases. The dental floss traction (DFT) method has been successfully used to facilitate ESE to resect mucosal lesions such as early gastric cancer. DFT has not been used in ESE to remove submucosal masses. This study aimed to examine the efficacy of DFT-assisted ESE (DFT- ESE) for the removal of submucous masses. Methods. From March 2017 to May 2017, a total of 12 patients with gastric submucosal masses at the First Affiliated Hospital of Nanchang University, Jiangxi, China, were enrolled. The tumor characteristics, en bloc resection rates, complications, and outcomes on follow-up were evaluated for all patients. Results. The 12 submucosal tumors were completely removed by DFT- ESE. Nine were gastrointestinal stromal tumors. Two were Schwannoma, located in the greater curvature of the gastric corpus. One was gastric ectopic pancreas. All the resected tumors were removed completely with intact tumor capsules. There was no more bleeding or perforation after the endoscopic closure of the perforation or the wound after the DFT-ESE, and no recurrences were identified at the time of follow-up. Conclusions.

The results show that a modular pattern centering on a few developers gradually emerges in the developer collaboration network after an evolutionary process of three stages. Core developers have completed a large proportion of the development work and played a coordinating role in development activities, while the periphery developers submit code to specific sub-projects according to their technical background, which complements the core developers' work. Furthermore, the modules of the developer collaboration network are intrinsically related to the sub-projects and continuously contribute code for the corresponding subprojects during the evolutionary process. These results may deepen our understandings of the collaborative pattern of OSS communities, and also have some reference value for the studies of open collaborative innovation in large scale crowds.","2019","2025-05-05 17:06:38","2025-05-05 17:06:38","","87-105","","NA","1103","","","","Communications in Computer and Information Science","","","","","","NA","","","","","","","Backup Publisher: Int Soc Knowledge & Syst Sci ISBN: 978-981-15-1209-4; 978-981-15-1208-7 Place: NA Publisher: NA","","","","NA","","Chen, J.; Huynh, V.; Nguyen, G.

Geistlich Bio-Oss Collagen is a natural mineral bone of bovine origin, comparable both chemically and structurally to the mineralized human bone. It has a spongy consistency that allows simple modeling, and collagen facilitates the adaptation of the material on the defect site.

The activity of tartrate-resistant bone acid phosphatase, on the contrary, decreased veridically by 22% over 60 days after implantation. Over 30 days after the beginning of the experiment under the action of the implanted material, the level of average molecules (AM) increased by 35% (p < 0.05), while nucleotide substances (NS) increased by 51% (p < 0.05). Within 60 days after implantation, the values of these indices showed a decreasing tendency. The fact mentioned above denotes that their osteoregenerative action increases under the influence of implanted materials.","2019-09","2025-05-05 17:06:39","2025-05-05 17:06:39","","3416-3418","","9","70","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, we explore an alternative way to organize a global software engineering course where students work on open source software development (OSSD) projects rather than in a multi-university collaboration setting. The results show that the new setup may provide core GSE challenges as well as challenges associated with software development outsourcing and challenges related to working on large open source software. The present article compares the experiences gained from running a combined GSE and OSSD course against the experiences gained from running a traditional GSE course. The two alternatives are compared in terms of students' learning outcomes and course organization. The authors found that a combined GSE and OSSD course provides learning opportunities that are partly overlapping with, and partly complementary to, a traditional GSE course. The authors also found that the combined OSSD and GSE course was somewhat easier to organize because most of the activities took place in a single university setting. The authors used the extended GSE taxonomy for the comparison and found it to be a useful tool for this, although it had some limitations in expressive power. Therefore, two additional relationship dimensions are proposed that will further enrich the extended taxonomy in classifying GSE (and OSSD) projects.","2019-02","2025-05-05 17:06:39","2025-05-05 17:06:39","","NA","","2, SI","19","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","OSS; Open Source Software Development; Global software engineering; GSE Education; GSE Taxonomy; Software Development Outsourcing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These include controlling user access to systems, resources, and data security issues that encompass secure storage, secure transmission, data authenticity and data integrity. These requirements are met by establishing the right policies, controls, and mechanisms that are put in place to effectively protect sensitive data. Therefore, this research aims to see if open source software has the potential to influence the cybersecurity market that is currently dominated by proprietary software. However, in order to accomplish such a task, certain conditions must be met. Such as understanding of the history behind open source software, the positive and negative influences it carries when dealing with this type of software. As well as compare and contrast current proprietary solutions with open source solutions, in order to grasp the potential economic impact of open source software leading onwards into the future. The ideal findings would be to outline the factors that are holding back open source software, and whether these factors are adjustable or correctable over time. Another aim is to highlight the potential financial benefit that comes from switching to or prioritizing OSS security solutions. As well as come up with any recommendations that would help aid businesses and organizations when it comes to obtaining suitable OSS security solutions.","2019","2025-05-05 17:06:40","2025-05-05 17:06:40","","115-127","","NA","NA","","","","Advances in Science Technology & Innovation","","","","","","NA","","","","","","","Backup Publisher: Amer Univ ISBN: 978-3-030-01659-3; 978-3-030-01658-6 Place: NA Publisher: NA","","","","NA","","AlMasri, A.; Curran, K.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the past, forest landscape has changed dramatically, especially in periods of forest over-exploitation. Previous studies in some Trentino sub-regions (Val di Fassa, Paneveggio) have identified these changes and the current trend of forest growth at the expenses of open areas, such as pastures and grasslands, due to the abandonment of rural areas. This phenomenon leads to the rapid Alpine landscape change and profoundly affects the ecological features of mountain ecosystems. To be able to monitor and to take future actions about this trend it is fundamental to know in detail the historical situation of the progressive changes on the land use that occurred over Trentino. The work aims to comprehensively reconstruct the forest cover of whole Trentino at high resolution (5m x 5m pixels) using a series of maps spanning a long period, consisting in historical maps, aerial images, remote sensed information and historical archives. The datasets were archived, processed and analyzed using the Free and Open Source Software (FOSS) GIS GRASS and QGIS. Historical maps include Atlas Tyrolensis (dated 1770), Theresianischer Kataster (dated 1859) and Italian Kingdom Forest Map (IKFM) of 1936. The aerial imagery dataset includes aerial images taken in 1954, which have been orthorectified during this research, and orthophotos available for years 1973, 1994, 2000, 2006, 2010 and 2016. Remote sensed information includes Landsat and recent Lidar data, while historical archives consist mostly in Forest Management Plans available since around 1950. The versatility of the wide variety of modules supplied from the FOSS GRASS and QGIS enabled to perform a diverse set of analysis and pre-processing (e.g.:orthorectification) on a heterogeneous dataset of input images. We will focus on the different strategies and methodologies implemented in the FOSS GIS used to process the various types of geographic data, challenges for the future of the research and the fundamental role of the FOSS systems in this process. Quantifying forest change in the time-span of our dataset can be used to perform further analysis on ecosystem services, such as protection from soil erosion, and on modification of biome diversity and to create future change scenarios.","2019","2025-05-05 17:06:40","2025-05-05 17:06:40","","71-78","","W14","42-4","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial\n Information Sciences","","","","","","NA","","","","","","","Backup Publisher: ISPRS ISBN: NA Place: NA Publisher: NA","","","","NA","","Brovelli, M.

Currently, FAQ chatbot is the most popular domain of use of dialog assistants. However, developing a chatbot project requires a full-stack team formed by numerous specialists, such as dialog designer, data scientist, software engineer, DevOps, business strategist and experts from the domain, which can be both time and resources consuming. Language processing can be particularly challenging in languages other than English due to the scarcity of training datasets. Most of the requirements of FAQ chatbots are similar, domain-specific, and projects could profit from Open Source Software (OSS) reuse. In this paper, we examine how OSS FAQ chatbot projects can benefit from reuse at the project level (black-box reuse). We present an experience report of a FLOSS FAQ chatbot project developed in Portuguese to an e-government service in Brazil. It comprises of the chatbot distribution service, as well as for analytics tool integrated and deployed on-premises. We identified assets that could be reused as a black-box and the assets that should be customized for a particular application. We categorized these assets in architecture, corpus, dialog flows, machine learning models, and documentation. This paper discusses how automation, pre-configuration, and templates can aid newcomers to develop chatbots in Portuguese without the need for specialized skills required from tools in chatbot architecture. Our main contribution is to highlight the issues non-English FAQ chatbots projects will likely face and the assets that can be reused. It allows non-chatbot experts to develop a quality-assured OSS FAQ chatbot in a shorter project cycle.","2019","2025-05-05 17:06:40","2025-05-05 17:06:40","","NA","","NA","NA","","","","OpenSym '19","","","","","","NA","","","","","","","Backup Publisher: Univ Skovde; Swedish Competit Author; ACM Special Interest Grp Software\n Engn; ACM SIGWEB; ACM In Cooperat ISBN: 978-1-4503-6319-8 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source; FLOSS; OSS; e-government; black-box reuse; conversational agents; experience report; FLOSS FAQ chatbot; portuguese chatbot","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Aims: In this paper, we examine the extent to which these problems still exist. We also study male and female contributors' perceptions of other contributors. Method: We surveyed participants from 15 FLOSS projects, asking a series of open-ended, closed-ended, and behavioral scale questions to gather information about the issue of gender in FLOSS projects. Results: Though many of those we surveyed expressed a positive sentiment towards females who participate in FLOSS projects, some were still strongly against their inclusion. Often, the respondents who were against inclusiveness also believed their own sentiments were the prevailing belief in the community, contrary to our findings. Others did not see the purpose of attempting to be inclusive, expressing the sentiment that a discussion of gender has no place in FLOSS. Conclusions: FLOSS projects have started to move forwards in terms of gender acceptance. However, there is still a need for more progress in the inclusion of gender-diverse contributors.","2019","2025-05-05 17:06:41","2025-05-05 17:06:41","","677-687","","NA","NA","","","","International Conference on Software Engineering","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp\n Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ\n Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme\n Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa\n Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE\n Comp Soc, Tech Comm Software Engn ISBN: 978-1-7281-0869-8 Place: NA Publisher: IEEE Press","","","","open source; survey; gender; floss","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, understanding how and why it occurs is important. To date, researchers have examined code reuse in OSS largely from the perspective of leaders. We show why followers must be considered as well. “Followers” are people who have had previous contacts with an individual from another project and who continue to associate with him or her. We consider two types of followers: developers (those directly involved in software development) and observers (those indirectly involved in it). We conduct a series of empirical investigations by using a longitudinal dataset of OSS projects hosted in GitHub, along with a survey and qualitative data. We find that followership can affect code reuse, but the effect depends on the nature of the follower (developer or observer). Overall, our study suggests that followership is important for code reuse in OSS because it enables participants to learn, and learning promotes code reuse.","2019-12","2025-05-05 17:06:42","2025-05-05 17:06:42","","1303+","","4","43","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Open source; Software; Open-source software; Software development; Public domain; Software project management; Software upgrading; Source code; Code reuse; Qualitative analysis; Computer programming; Datasets; Followership","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, they are less suited for operation as production level models due to their slow simulation performance. This paper presents a new extension to the EDD that offers C++ model performance coupled with the convenience of EDD modelling. The extended form of the EDD is called a Verilog-A EDD or VAEDD for short. It has the same structure as the standard EDD but is built around compiled Verilog-A module code, which in turn is translated to C++ code and dynamically linked to the main body of the simulator code. Essentially a VAEDD is a tiny Verilog-A module with a standardised internal code structure. To demonstrate the interactive approach to compact model building with VAEDD components the design and testing of a high power SiC Schottky barrier diode is included in the main body of the text.","2019","2025-05-05 17:06:43","2025-05-05 17:06:43","","92-97","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: IEEE; Lodz Univ Technol, Dept Microelectron & Comp Sci; Warsaw Univ\n Technol, Inst Microelectron & Optoelectron; Poland Sect IEEE ED & CAS\n Chapters; Polish Acad Sci, Comm Elect & Telecommunicat, Sect\n Microelectron & Electron Technol; Polish Acad Sci, Comm Elect &\n Telecommunicat, Sect Signals, Elect Circuits & Syst; Int Union Radio\n Sci, Polish Natl Comm, Commiss Elect & Photon ISBN: 978-83-63578-16-9 Place: NA Publisher: NA","","","","NA","","Napieralski, A.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As such access to PHC services is an important factor to ensure good health of a community. While the need to provide equal and easy access to PHC is well understood, the approaches informing the decision-making process to improve the access tend to face a number of challenges in the developing world. Use of conventional Information and Communication Technologies (ICTs) comes with requisite financial costs which Free and Open Source Software (FOSS) ICT technologies have the potential to help lower among other benefits. In this study, the confluence of spatial accessibility tools provided by FOSS technologies, specifically PostgreSQL/PostGIS and QGIS, was explored to inform decision making in PHC accessibility in Zomba, Malawi. The results show that the household population (P) that is within the threshold time was 8, representing % of all households having access to health care. The mean accessibility score for the district was 0.010 and ranged from 0.00 to 0.231. While the findings provide, arguably, spatially objective PHC accessibility data to inform policy direction and also reveals accessibility to PHC in Malawi to be lower than reported, the study also reveals the usefulness of FOSS technologies, in the developing world. Use of FOSS facilitated incremental setup of the model thereby allowing to run the model with limited processing power. That notwithstanding, the study adds to the formal scientific research on the use of relational spatial analysis in the developing world.","2019","2025-05-05 17:06:44","2025-05-05 17:06:44","","189-195","","W14","42-4","","","","International Archives of the Photogrammetry, Remote Sensing and Spatial\n Information Sciences","","","","","","NA","","","","","","","Backup Publisher: ISPRS ISBN: NA Place: NA Publisher: NA","","","","NA","","Brovelli, M.

Small opaque chambers can be used to measure leaf, stem and soil respiration. Larger transparent chambers can be used to measure net ecosystem exchange of CO2, and small jars often serve this purpose for laboratory incubations of soil and plant material. We developed an Android application (app), called Flux Puppy, to facilitate chamber-based flux measurements in the field and laboratory. The app is designed to run on an inexpensive handheld Android device, such as a tablet or phone, and it has a graphical user interface that communicates with a LI-COR LI-820 and LI-830 (CO2) or LI-840 and LI-850 (CO2/H2O) infrared gas analyzer. The app logs concentrations of CO2 and H2O, cell temperature and pressure at 1 Hz, displays the output graphically, and calculates the linear regression slope, R-squared, and standard error of the CO2 time series. A metadata screen allows users to enter operator, site, and plot information, as well as take a photograph using the Android device's built-in camera, and log measurement location using the device GPS. Additionally, there is a notes field, which can be revised after the measurements are taken. Data files (the 1 s raw data, photograph, and metadata including statistics calculated from the raw data) are then transmitted off the device through file sharing options (Gmail, Outlook, Google Drive, Dropbox etc.). Because Flux Puppy code is open-source (available on GitHub) and the flux measurement system we describe is relatively inexpensive and straightforward to assemble, it should be of broad interest to the carbon cycling community.","2019-08-15","2025-05-05 17:06:47","2025-05-05 17:06:47","","1-6","","NA","274","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The article will begin with an overview of the history and context of FOSS licenses and FRAND-based licensing regimes, continue with a legal review of the actual language of prominent FOSS licenses, and provide further thoughts on future opportunities and challenges for the interaction between FOSS projects and standard processes, with a particular view on FOSS implementations of standards.","2019-07","2025-05-05 17:06:48","2025-05-05 17:06:48","","78-102","","3-4","22","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","Open Source Software; FRAND licenses; Standard Essential Patents","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this article we argue that disadvantage is more due to gendered behavior than to categorical discrimination: women are at a disadvantage because of what they do, rather than because of who they are. Using data on entire careers of users from GitHub.com, we develop a measure to capture the gendered pattern of behavior: We use a random forest prediction of being female (as opposed to being male) by behavioral choices in the level of activity, specialization in programming languages, and choice of partners. We test differences in success and survival along both categorical gender and the gendered pattern of behavior. We find that 84.5% of women's disadvantage (compared to men) in success and 34.8% of their disadvantage in survival are due to the female pattern of their behavior. Men are also disadvantaged along their interquartile range of the female pattern of their behavior, and users who don't reveal their gender suffer an even more drastic disadvantage in survival probability. Moreover, we do not see evidence for any reduction of these inequalities in time. Our findings are robust to noise in gender recognition, and to taking into account particular programming languages, or decision tree classes of gendered behavior. Our results suggest that fighting categorical gender discrimination will have a limited impact on gender inequalities in open source software development, and that gender hiding is not a viable strategy for women.","2019-07-06","2025-05-05 17:06:48","2025-05-05 17:06:48","","NA","","NA","8","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER","","","","Open source; Software development; Gender inequality; Gendered behavior","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender-balanced, women-friendly and inclusive workplace certainly would benefit from a more diverse environment.

Multi-release development of OSS can provide an opportunity to inculcate the dynamic needs of the user in a very short span of time to survive in the market. In spite of having these benefits, numerous challenges can be faced during the multi-release OSS development. Some of the challenges can be the generation of errors during the addition of new features. To address the changing fault detection process, a change point phenomenon is considered so as to give more practicality to the model. In this article, we present a general framework for multi-release OSS modelling incorporating imperfect debugging and change points.

This paper attempts to investigate whether the Open Source Software research produces results considered relevant to undergraduate students. This way we can provide feedback from the students, offering a way to produce useful and, consequently, more disseminated works among Open Source practitioners. To answer about the relevance of available work, we have tackled two questions: one about the scope of the studies and another about the quality perceived by them. For the first one, a systematic mapping was conducted, revealing a set of works composed by a great diversity of results. Than, we applied a Survey in which students could evaluate the relevance of these gathered works.

The approach offers a way to capture motion adapted from the film industry in which markers placed on the skin of the face can be tracked with a pattern-matching algorithm. The method records and postprocesses raw facial movement data (coordinates per frame) of distinctly placed markers and is intended for use in facial expression research (e.g., microexpressions) in laboratory settings. Due to the explicit use of specifically placed, artificial markers, the procedure offers the simultaneous measurement of several emotionally relevant markers in a (psychometrically) objective and artifact-free way, even for facial regions without natural landmarks (e.g., the cheeks). In addition, the proposed procedure is fully based on open-source software and is transparent at every step of data processing. Two worked examples demonstrate the practicability of the proposed procedure: In Study 1(N=39), the participants were instructed to show the emotions happiness, sadness, disgust, and anger, and in Study 2 (N=113), they were asked to present both a neutral face and the emotions happiness, disgust, and fear. Study 2 involved the simultaneous tracking of 14 markers for approximately 12 min per participant with a time resolution of 33 ms. The measured facial movements corresponded closely to the assumptions of established measurement instruments (EMFACS, FACSAID, Friesen & Ekman, 1983; Ekman & Hager, 2002). In addition, the measurement was found to be very precise with sub-second, sub-pixel, and sub-millimeter accuracy.","2019-04","2025-05-05 17:07:20","2025-05-05 17:07:20","","747-768","","2","51","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, an efficient approach to evaluate the health status of the open-source project is needed. Unfortunately, although many approaches including metrics have been proposed, they are designed in arbitrary ways. In this paper, a math ematical tool, i.e., factor analysis, is used to build a health evaluation model for OSS projects. As far as we know, this is the first time that factor analysis has been applied to evaluate OSS projects. This model is based on GitHub data and uses the basic indexes that are closely related to the health status of the projects as the input. Then, six new synthetic metrics, namely community activity, project popularity, development activity, completeness, responsiveness and persistence are obtained through factor analysis, which can be used to calculate the overall health score of a project. Moreover, in order to verify the effectiveness of this model, it is applied to some real projects and the results show that the overall scores achieved by this model can reflect the health status of the projects.","2019","2025-05-05 17:07:20","2025-05-05 17:07:20","","723-737","","NA","1042","","","","Communications in Computer and Information Science","","","","","","NA","","","","","","","Backup Publisher: China Comp Fed, Tech Comm on Cooperative Comp, Kunming Univ of Sci and\n Technology ISBN: 978-981-15-1377-0; 978-981-15-1376-3 Place: NA Publisher: NA","","","","NA","","Sun, Y.; Lu, T.; Yu, Z.; Fan, H.; Gao, L.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the first example, the turbine blade is reconstructed automatically from a structured point cloud. Another example is the interactive reconstruction of the turbine blade from an unstructured surface triangulation. In both the cases, we use a surface skinning strategy enhanced by a curve fairing operator. We show that the modified skinning operator does not minimize the total bending energy of the surface, but yields a smooth patch where input inaccuracies are compensated for. The reconstruction result is a parametric model of the turbine blade where the design variables are the coordinates of the poles for each profile curve. The proposed software architecture can be used for partial or complete parameterization of reconstructed CAD models with the aim of their subsequent optimization.","2019-07","2025-05-05 17:07:22","2025-05-05 17:07:22","","202-212","","4","45","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

First, according to the snowball sampling data collection method and the grounded theory, the data is collected and processed. Second, by designing evaluation indicators and utility functions, the projection pursuit classification model of the natural ecosystem is evaluated and combined with a real-coded accelerated genetic algorithm, thereby designing the health measure model. The experimental results suggest the effectiveness of the proposed approach.","2019","2025-05-05 17:07:23","2025-05-05 17:07:23","","87396-87409","","NA","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This decision is partly justified due to the difficulty of bringing to the context of a classroom a real software project. The widespread presence of open source projects, however, is contributing to alleviating this problem. Several instructors have already adopted contributions to open source projects as part of their evaluation process, and these instructors reported many benefits, including the improvement on students' technical and social skills. However, little is known about the students' perceptions regarding the need to contribute to an open source project as part of a Software Engineering course. To better understand the students' challenges, benefits, and attitudes, we conducted 21 semi-structured interviews with students who took these courses in five different Brazilian universities. We also enriched this data with an analysis of commits performed in the repositories that students contributed to. We observed that even though some instructors chose the open source projects to students to work themselves, some students and even the open source community participated in the process of choosing projects and tasks. Students' contributions varied concerning both complexity (measured by the number of additions, deletions, and edited files) and diversity (measured regarding the different programming languages used). Among the benefits, students reported improving their technical skills and their self-confidence. Finally, some students found extremely important for instructors' being involved with open source initiatives (extra-classroom).","2019","2025-05-05 17:07:23","2025-05-05 17:07:23","","147-157","","NA","NA","","","","ICSE-SEET '19","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Comp Soc Tech Comm\n Software Engn; ACM Special Interest Grp Software Engn; Natl Sci Fdn;\n Facebook; IBM; Huawei; Monash Univ; Univ Waterloo; Ecole Technologle\n Super; Amazon Web Serv; Tourisme Montreal; Google; Microsoft Res;\n Blackberry; Fujitsu; Univ Calif; ING; Nat Sci & Engn Res Council\n Canada; Prompt ISBN: 978-1-7281-1000-4 Place: NA Publisher: IEEE Press","","","","open source software; open source communities; software engineering courses","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although related qualitative and quantitative studies point out the gender gap, the technical and social interaction of females within OSS still remain unexplored and largely misunderstood. As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions. Thus, we propose to answer the questions: where are females in OSS projects? How they evolve? and How they contribute to the sustainability of the OSS social capital?. We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity. We found that females are extremely underrepresented within OSS communities, but when they participate they are productive just as males, they evolve following relatively the same patterns than males and remain more involved in projects than males.","2019","2025-05-05 17:07:25","2025-05-05 17:07:25","","308-319","","NA","NA","","","","IFIP Advances in Information and Communication Technology","","","","","","English","","","","","","","Backup Publisher: IFIP WG 5 5 COVE Co Operat infrastructure Virtual Enterprises & Elect\n Business; Soc Collaborat Networks; Politecnico Torino; Nova Univ Lisbon;\n UNINOVA; Univ Amsterdam ISBN: 978-3-030-28464-0; 978-3-030-28463-3 Place: GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND Publisher: SPRINGER INTERNATIONAL PUBLISHING AG","","","","Open Source Software; Social Network Analysis; Diversity; Gender; \n Socio-Technical interactions","","CamarinhaMatos, L.

To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated.

Code review is an emotionally loaded practice, with public exposure of reputation and ample opportunities for conflict. We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process. It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market. In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.","2019","2025-05-05 17:07:27","2025-05-05 17:07:27","","1073-1083","","NA","NA","","","","International Conference on Software Engineering","","","","","","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; ACM Special Interest Grp\n Software Engn; Natl Sci Fdn; Facebook; IBM; Huawei; Monash Univ; Univ\n Waterloo; Ecole Technologie Superieure; Amazon Web Serv; Tourisme\n Montreal; Google; Microsoft Res; Blackberry; Fujitsu; Univ Calif Santa\n Barbara, Comp Sci; ING; Nat Sci & Engn Res Council Canada; Prompt; IEEE\n Comp Soc, Tech Comm Software Engn ISBN: 978-1-7281-0869-8 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","Motivation; Open Source; Code Review","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Through an exploratory data analysis we found that projects are staffed by a plurality of enterprise insiders, who appear to be pulling more than their weight, and that in a small percentage of relatively large projects development happens exclusively through enterprise insiders.","2020","2025-05-05 17:07:31","2025-05-05 17:07:31","","533-537","","NA","NA","","","","IEEE International Working Conference on Mining Software Repositories","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software\n Engn; ACM Special Interest Grp Software Engn; Korean Inst Informat\n Scientists & Engineers ISBN: 978-1-4503-7517-7 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","dataset; EDGAR; Fortune Global 500; open source software in business; SEC 10-K; SEC 20-F; software ecosystems; Software engineering economics","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors' learning processes is an important research area in OSS.

In this paper, we describe how data science, which combines computer programming, domain knowledge, and analytic skillsets to scientifically extract insights from data, can be used to help meet the growing demand of analytic needs across an organization's value chain.

Apart from its typical RE process, there is a competing process, external to the firm and inherent to the firm's ecosystem. When trying to impose an agenda in competition with other firms, and aiming to align internal product planning with the ecosystem's RE process, firms need to consider who and how influential the other stakeholders are, and what their agendas are. The aim of the presented research is to help firms identify and analyze stakeholders in OSS ecosystems, in terms of their influence and interactions, to create awareness of their agendas, their collaborators, and how they invest their resources. To arrive at a solution artifact, we applied a design science research approach where we base artifact design on the literature and earlier work. A stakeholder influence analysis (SIA) method is proposed and demonstrated in terms of applicability and utility through a case study on the Apache Hadoop OSS ecosystem. SIA uses social network constructs to measure the stakeholders' influence and interactions and considers the special characteristics of OSS RE to help firms structure their stakeholder analysis processes in relation to an OSS ecosystem. SIA adds a strategic aspect to the stakeholder analysis process by addressing the concepts of influence and interactions, which are important to consider while acting in collaborative and meritocratic RE cultures of OSS ecosystems.","2020-03","2025-05-05 17:07:36","2025-05-05 17:07:36","","115-130","","1","25","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

When the measurement data is assumed to be obtained on a uniform grid which is staggered with respect to the discretization of the parameter volume, the resulting kernel sensitivity matrices exhibit block-Toeplitz-Toeplitzblock (BTTB) structure. These matrices are symmetric for the gravity problem but unsymmetric for the magnetic problem. In each case, the structure facilitates fast forward computation using two-dimensional fast Fourier transforms. The construction of the kernel matrices and the application of the transform for fast forward multiplication, for each problem, is carefully described. But, for purposes of comparison with the non-transform approach, the generation of the unique entries that define a given kernel matrix is also explained. It is also demonstrated how the matrices, and hence transforms, are adjusted when padding around the volume domain is introduced. The transform algorithms for fast forward matrix multiplication with the sensitivity matrix and its transpose, without the direct construction of the relevant matrices, are presented. Numerical experiments demonstrate the significant reduction in computation time and memory requirements that are achieved using the transform implementation. Thus, it becomes feasible, both in terms of reduced memory requirements and computational time, to implement the transform algorithms for large three-dimensional volumes. All presented algorithms, including with variable padding, are coded for optimal memory, storage and computation as an open source MATLAB code which can be adapted for any convolution kernel which generates a BTTB matrix, whether or not it is symmetric. This work, therefore, provides a general tool for the efficient simulation of gravity and magnetic field data, as well as any formulation which admits a sensitivity matrix with the required structure.","2020-11","2025-05-05 17:07:37","2025-05-05 17:07:37","","NA","","NA","144","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Cross-language software similarity detection is inherently more challenging due to variations in language, application structures, support libraries used, and naming conventions. In this paper we propose a novel model, CroLSim, to detect similar software applications across different programming languages. We define a semantic relationship among cross-language libraries and API methods (both local and third party) using functional descriptions and a word-vector learning model. Our experiments show that CroLSim can successfully detect cross-language similar software applications, which outperforms all existing approaches (mean average precision rate of 0.65, confidence rate of 3.6, and 75% highly rated successful queries). Furthermore, we applied CroLSim to a source code repository to see whether our model can recommend cross-language source code fragments if queried directly with source code. From our experiments we found that CroLSim can recommend cross-language functional similar source code when source code is directly used as a query (average precision=0.28, recall=0.85, and F-Measure=0.40).

Finally, by adjusting input parameters for issue resolution process, we analyze the impact of these parameters, which shows this system also helps understand how to control the open source software development process.","2020","2025-05-05 17:07:39","2025-05-05 17:07:39","","164-170","","NA","NA","","","","IEEE World Congress on Services","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 978-1-7281-8203-2 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Static analyzers can be useful to software developers in detecting and locating code issues and, in addition, classifying their nature. The main problem of static analyzers, however, is that they may signal too many false alarms. Objective. In this paper, we investigate whether code issues that are detected by SpotBugs persist in software code, or if they get removed. We chose SpotBugs because it is one of the best-known and most used static analyzers. Method. We carried out an empirical study on five open-source Java programs and took into account two versions of each of them, to check whether the issues signaled by SpotBugs on the older version had been removed by the time the newer version was released. A total of 1,006 issues were signaled by SpotBugs. Results. Our results show that about half of the issues signaled disappeared between the two versions, but the correction rate was uneven across projects. Issues about the correctness of software code were more likely to be no longer present in the newer version than other types of warnings. Conclusions. Further investigations are required, to understand why some projects appear more active than others in correcting SpotBugs issues, and why very few high-severity warnings were observed in the analyzed code. Nonetheless, the fact that about half of the issues flagged by SpotBugs were removed indicates that the tool is effective in detecting incorrect or otherwise problematic code.","2020","2025-05-05 17:07:39","2025-05-05 17:07:39","","144-151","","NA","1266","","","","Communications in Computer and Information Science","","","","","","NA","","","","","","","Backup Publisher: Univ Algarve; ACM; Quidgest; ATOS ISBN: 978-3-030-58792-5; 978-3-030-58793-2 Place: NA Publisher: NA","","","","NA","","Shepperd, M.; Abreu, F.

Especially in software ecosystems, the dynamics of interactions with interventions of external developers over a common technological platform leverage the effects of influence and still remains as a challenge. This paper presents an exploratory study on the sense of influence in open source software ecosystems, more specifically from the opinions of 95 developers who contribute to npm projects based on GitHub. To do so, qualitative data from a conducted survey research were analyzed based on Grounded Theory ( GT) procedures. Based on two main categories (Technical and Social), we recognized aspects that reinforce some key characteristics of an influencer, e.g., `status in the project', `participation with code', `participation with comments', and `content value'. However, some diverging aspects were observed, e.g., the difference between qualitative and quantitative responses related to `long-time interaction with the project'. This study contributes with the identification of influencers' characteristics that can aid both researchers in further studies on open source software ecosystems and practitioners in strategies to manage project-based ecosystems.","2020","2025-05-05 17:07:40","2025-05-05 17:07:40","","137-146","","NA","NA","","","","SBES '20","","","","","","NA","","","","","","","Backup Publisher: Univ Fed Rio Grande Norte; UERN; Loggi; Google; Conselho Nacl\n Desenvolvimento Cientifico & Tecnologico; Software Engn Team Res &\n Innovat; Inst Metropole Digital; UFRN, DIMAP ISBN: 978-1-4503-8753-8 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","GitHub; Open Source; Influence; Software Ecosystems; npm; Social Developer","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We argue that these aspects are important, however, technical security practice considering different social aspects of OSS development will assure the effectiveness and efficiency of the implementation of the tool. To mitigate this research gap, in this empirical study, we explore the current security culture in the OSS development phenomenon using a survey instrument with six evaluation dimensions: attitude, behavior, competency, subjective norms, governance, and communication. By exploring the current security culture in OSS communities, we can start to understand the influence of security on participants' security behaviors and decision-making, so that we can make realistic and practical suggestions.

Clinical use with prostate gold fiducial markers is presented. Methods Projections of regions of interest (ROI) in the reference frame of the electronic portal imaging device are computed offline for different gantry angles before the first treatment fraction. During treatment delivery, the contrast of portal images is automatically adjusted using a histogram equalization algorithm. The projections associated with the current gantry angle are then superimposed on the images in real time. This allows the therapist to evaluate if the imaged structures of interest remain within their respective contours during treatment delivery and to potentially interrupt the treatment if deemed necessary. The spatial accuracy of the method was evaluated by imaging a ball bearing phantom in a set-up where the position of the projected ROI is highly sensitive to gantry angle errors. The visibility of fiducial markers during one fraction of seven different volumetric modulated arc therapy (VMAT) prostate treatments is characterized. Results The geometric validation showed a negligible systematic error mu < 0.1 mm for the position of the projections. The random errors associated with the time accuracy of the gantry angle readout were characterized by standard deviations sigma <= 0.6 mm. The VMAT clinical treatments showed that the fiducial markers were frequently visible, allowing for a meaningful clinical use. Conclusions The results demonstrate that the method presented is sufficiently accurate to be used for intrafraction monitoring of patients. The fact that this method could be implemented on many modern linacs at little to no cost and with no additional dose delivered to the patients makes this solution very attractive for improving patient care and safety in radiation therapy.","2020-08","2025-05-05 17:07:41","2025-05-05 17:07:41","","173-182","","8","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Key considerations when considering prognostic enrichment include: clinical trial sample size; the number of patients one must screen to enroll the trial; and total patient screening costs and total per-patient trial costs. The Biomarker Prognostic Enrichment Tool for Survival Outcomes (BioPETsurv) is a suite of methods for estimating these elements to evaluate a prognostic enrichment biomarker and/or plan a prognostically enriched clinical trial with a time-to-event primary endpoint. BioPETsurv allows investigators to analyze data on a candidate biomarker and potentially censored survival times. Alternatively, BioPETsurv can simulate data to match a particular clinical setting. BioPETsurv's data simulator enables investigators to explore the potential utility of a prognostic enrichment biomarker for their clinical setting. Results demonstrate that both modestly prognostic and strongly prognostic biomarkers can improve trial metrics such as reducing sample size or trial costs. In addition to the quantitative analysis provided by BioPETsurv, investigators should consider the generalizability of trial results and evaluate the ethics of trial eligibility criteria.

This increase in digital recordings necessitates an increase in high-throughput methods of analysis for researchers. Specifically, there is a need in the community for open-source methods that are tailored to recordings of varying qualities and from multiple species collected in nature. We developed Chipper, a Python-based software to semi-automate both the segmentation of acoustic signals and the subsequent analysis of their frequencies and durations. For avian recordings, we provide widgets to best determine appropriate thresholds for noise and syllable similarity, which aid in calculating note measurements and determining song syntax. In addition, we generated a set of synthetic songs with various levels of background noise to test Chipper's accuracy, repeatability and reproducibility. Chipper provides an effective way to quickly generate quantitative, reproducible measures of birdsong. The cross-platform graphical user interface allows the user to adjust parameters and visualize the resulting spectrogram and signal segmentation, providing a simplified method for analysing field recordings. Chipper streamlines the processing of audio recordings with multiple user-friendly tools and is optimized for multiple species and varying recording qualities. Ultimately, Chipper supports the use of citizen-science data and increases the feasibility of large-scale multi-species birdsong studies.","2020-04","2025-05-05 17:07:46","2025-05-05 17:07:46","","524-531","","4","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

An increasing rate of urban growth and urban sprawl could induce changes in land use as well as land transformation. However, accurate and up-to-date information about LULC is required for providing better understanding and assessing the environmental consequences of such changes. In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80% and 80.40% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification. To summarize, ArcGIS and QGIS software are reliable to be used in the land cover classification.","2020","2025-05-05 17:07:46","2025-05-05 17:07:46","","NA","","NA","540","","","","IOP Conference Series-Earth and Environmental Science","","","","","","English","","","","","","","Backup Publisher: Inst Geospatial & Remote Sensing Malaysia; Univ Putra Malaysia; Sc &\n Technol Res Inst Def; Univ Teknologi Malaysia; Univ Utara Malaysia; Int\n Islam Univ Malaysia; Forest Res Inst Malaysia; GIS Innovat Sdn Bhd; GPS\n Lands M Sdn Bhd; IEEE Geoscience & Remote Sensing Soc, Malaysia Chapter ISBN: NA Place: DIRAC HOUSE, TEMPLE BACK, BRISTOL BS1 6BE, ENGLAND Publisher: IOP PUBLISHING LTD","","","","NA","","Omar, H.; Shariff, A.

Following the original study, we analyze project development data, archived in the GitHub repository, for the OSS project Rubinius. The analysis explores relationships among development and developer interdependencies as well as activity and order variation. Further, we extend the original study by examining the core relationships in the original study and investigating the external generalizability of the results by replicating the analysis on three analogous OSS projects: JRuby, mruby, and RubyMotion. These offer an opportunity to evaluate the generalizability of the original study to projects of different sizes and amount of activity, yet similar otherwise to the project in the original study. Another extension is the use of an additional control variable, length of activity sequence, which proves to have substantial implications of the study’s focal relationships.

These techniques make it possible to study internal features by non-destructive analysis. Despite its potential, the development of 3D imaging in the Geosciences is behind other fields due to the high cost of commercial software and the scarce free alternatives. Most free software was designed for the Health Sciences, and the pre-settled workflows are not suited to geoscientific materials. Thus, an outstanding challenge in the Geosciences is to define workflows using free alternatives for Computed Tomography (CT) data processing, promoting data sharing, reproducibility, and the development of specific extensions. We present CroSSED, a processing sequence for 3D reconstructions of CT data, using 3DSlicer, a popular application in medical imaging. Its usefulness is exemplified in the study of burrows that have low-density contrast with respect to the host sediment. For geoscientists who have access to CT data and wish to reconstruct 3D structures, this method offers a wide range of possibilities and contributes to open-science and applied CT studies.","2020-08-14","2025-05-05 17:07:48","2025-05-05 17:07:48","","NA","","1","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.","2020","2025-05-05 17:07:48","2025-05-05 17:07:48","","484-510","","NA","46","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS","","","","OSS; Decision Making; Decision Process; F/LOSS; Free/Libre Open Source Software\n Development","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We introduce a novel method for determining the data of a weak electrolyte by the nonlinear regression of effective electrophoretic mobility versus buffer composition dependence when measured in a set of BGEs with various pH. To correct the experimental data for zero ionic strength we use the extended Debye-Huckel model and Onsager-Fuoss law with no simplifications. Contrary to contemporary approaches, the nonlinear regression is performed on limiting mobility data calculated by PeakMaster's correction engine, not on the raw experimental mobility data. Therefore, there is no requirement to perform all measurements at a constant ionic strength of the set of BGEs. We devised the computer program AnglerFish that performs the necessary calculations in a user-friendly fashion. All thermodynamic pKa values and limiting electrophoretic mobilities for arbitrarily charged substances having any number of ionic forms are calculated by one fit. The user input consists of the buffer composition of the set of BGEs and experimentally measured effective mobilities of the inspected weak electrolyte.","2020-04","2025-05-05 17:07:49","2025-05-05 17:07:49","","493-501","","7-8, SI","41","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Can such an instrument be developed and tested to assist with automated detection of materials, possibly from space? We tested two spectrometer designs inside a two unit (2U) cubesat frame against a series of materials exhibiting phenomenology in the visible/near infrared (Vis/NIR) portion of the spectrum and vegetation groups. This was conducted in order to determine whether open source designs were capable of discriminating against similar materials, such as types of vegetation or types of iron-rich minerals. A spectral pipeline was created using open source programming software that was capable of converting raw sensor data into spectra, comparing samples of interest against a spectral library and returning an identification result with a confidence interval.

In the case of biological sciences, information commons, such as public biobanks and free/libre open source software (FLOSS), are of paramount importance for both research and the bioeconomy. In a time of digitalization, however, information commons are vulnerable to violations, such as the free-rider problem, that render the commons unsustainable. Consequently, it has been argued that the enclosure of the informational common resources is the only means to effectively exploit them. Given the social and economic importance of the information commons, the new digital environment in biology and health requires governance innovation that will regulate the social embedding of the commons and their relationship to the free market, that is, a new political economy is needed. In this context, the need for a core common infrastructure, stretching from the physical to the logical and content layer of the information environment, that will guarantee the protection of the commons from both violations and enclosures, has been highlighted. Focusing on the interaction between two biological/bioinformatics commons, namely public biobanks and the FLOSS, we have set up an ecosystem relying on a blockchain technology. The proposed governance mechanism protects the information commons from the free-rider problem and guarantees their sustainability without hampering their operational framework. Our model demonstrates the interdependence and protection of the information commons not as an abstract theoretical exercise, but rather as a physical reality on the digital ontological matrix.","2020-05-01","2025-05-05 17:07:50","2025-05-05 17:07:50","","278-285","","5","24","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC","","","","digitalization; political economy; blockchain; free; libre open source software; the commons; public\n biobanks","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, a microRNA-activated scaffold constituted of microRNA21 nanoparticles combined with porous Bio-Oss particles was designed for the use of accelerating the early stage healing of the alveolar bone. It was noteworthy that the regeneration of alveolar bone was rapidly promoted to be shortened from the ordinary 3 months to 2 weeks.

Moreover, the continuous evolution of software due to bugs removal, new features addition or existing features modification results in the source code complexity. The proposed model quantifies the complexity in the source code using the Shannon entropy measure. In addition, the issues fixing growth behavior is viewed as a function of continuation time of the software in the field environment and amount of uncertainty or complexity present in the source code. Therefore, a two-dimensional function called Cobb-Douglas production function is applied to model the intensity function of the issues fixing rate. Furthermore, the rate of fixing the different issue types is considered variable that may alter after certain time points. Thus, this study incorporates the concept of multiple change-points to predict and assess the fixing behavior of issues in the software system. The performance of the proposed model is validated by fitting the proposed model to the actual issues data of three open-source projects.

The concept of peer governance describes the interaction and convergence of companies, foundations, voluntary users and professionals in its development. Methodology/approach: The research is based on the documentary method and an organizational history approach. For this, primary and secondary digital sources were collected: institutional and FLOSS sites, blogs, community lists, documents and platforms. Originality/Relevance: The work allows progress, from a sociotechnical perspective, in understanding FLOSS developments and the coevolution of their technical components and community dynamics. Main results: Three levels of governance are identified: 1. the software itself; 2. the community; 3. the ecosystem. Development cycles; community participation and organization; actors and business models, definitions and controversies, are analyzed. GNOME's trajectory is marked by the confluence of interests and coopetition between corporate actors and the FLOSS ecosystem. The life cycle shows a constant activity, which implies redefinition of its components, technological infrastructure and leadership. It is not exempt from controversies and bifurcations, similar to those evidenced in projects of this type. Theoretical/methodological contributions: It contributes to the concept of peer governance and its usefulness for case analysis.

Here we pull together, and in some cases improve, extant methods into a single software tool, written as a package in the R statistical framework. The workflow is validated using Escherichia coli engineered to express green fluorescent protein (GFP) from a set of commonly used constitutive promoters. We then demonstrate the package's power by identifying the time evolution of distinct subpopulations of bacteria from bulk plate reader data, a task previously reliant on laborious flow cytometry or colony counting experiments.

Four-dimensional cine models allow for real-time visualization of cardiac structures during processes such as complex congenital heart disease. Such models can be used for patient and trainee education, and potentially for surgical planning. Currently, 3-D printed models are more commonly used, but they are static, showing only one selected phase of the cardiac cycle. Second, they are limited by the selection of clipping planes before printing. Four-dimensional segmentation and virtual reality visualization overcome these limitations. Currently, most of the work in virtual/augmented reality models involves the segmentation of one cardiac phase or the use of expensive software for multiphase segmentation. In this study, we show an approach for multiphase cardiac segmentation as well as its display using free open-source software and relatively inexpensive hardware.","2020-10","2025-05-05 17:07:55","2025-05-05 17:07:55","","1617-1623","","11","50","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Satellite remote sensing is the optimal tool to provide such data. Images from Synthetic Aperture Radar (SAR) satellite sensors are preferably used as they work regardless of cloud coverage during image acquisition. However, processing of SAR is more complicated and the sensors have development potential. Dealing with such a complexity, current studies should aim to be reproducible, open, and built upon free and open-source software (FOSS). Thereby, the data can be reused to develop and validate new algorithms or improve the ones already in use. This paper presents a case study of crop classification from microwave remote sensing, relying on open data and open software only. We used 70 multitemporal microwave remote sensing images from the Sentinel-1 satellite. A high-resolution, high-precision digital elevation model (DEM) assisted the preprocessing. The multi-data approach (MDA) was used as a framework enabling to demonstrate the benefits of including external cadastral data. It was used to identify the agricultural area prior to the classification and to create land use/land cover (LULC) maps which also include the annually changing crop types that are usually missing in official geodata. All the software used in this study is open-source, such as the Sentinel Application Toolbox (SNAP), Orfeo Toolbox, R, and QGIS. The produced geodata, all input data, and several intermediate data are openly shared in a research database. Validation using an independent validation dataset showed a high overall accuracy of 96.7% with differentiation into 11 different crop-classes.","2020-02","2025-05-05 17:07:55","2025-05-05 17:07:55","","NA","","2","9","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","remote sensing; ancillary information; land use land cover; machine\n learning algorithms","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given this characteristic, OSS communities have been studied as technical communities, where stakeholders join and evolve in their careers based on their (often voluntary) code contributions to the project. However, the OSS landscape is slowly changing with more people and companies getting involved in OSS. This means that projects now need people in non-technical roles and activities to keep the project sustainable and evolving. In this paper, we focus on understanding the roles and activities that are part of the current OSS landscape and the different career pathways in OSS. By conducting and analyzing 17 interviews with OSS contributors who are well known in the community, we provide empirical evidence of the existence and importance of community-centric roles (e.g advocate, license manager, community founder) in addition to the well-known project-centric ones (e.g maintainer, core member). However, the community-centric roles typically remain hidden, since these roles may not leave traces in software repositories typically analyzed by researchers. We found that people can build a career in OSS through different roles and activities, with different backgrounds, including those not related to writing software. Furthermore, people's career pathways are fluid, moving between project and community-centric roles. Our work highlights that communities and researchers need to take action to acknowledge the importance of these varied roles, making these roles visible and well-recognized, which can ultimately help attract and retain more people in the OSS projects.","2020-10","2025-05-05 17:07:57","2025-05-05 17:07:57","","NA","","CSCW2","4","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open-source; collaborative development; career; role","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As a society advancing towards the democratization of information and collaborative processes, the researchers should not only focus on improving the efficacy of filters, but should also consider the users' needs with a view toward improving the usability and accessibility of the filters in order to develop tools that will provide solutions to the challenges facing this field of study. In this work, we describe the Hybrid Overlap Filter (HyOF), a new filtering algorithm implemented in the free R software environment. The flow diagram of HyOF differs in the following ways from that of other filters developed to date: (1) the algorithm is formed by a combination of sequentially operating functions (i.e., the output of the first function provides the input of the second), which are capable of functioning independently and thus enabling integration of these functions with other filtering algorithms; (2) the variable penetrability is defined and used, along with slope and elevation, to identify ground points; (3) prior to selection of the seed points, the original point cloud is processed with the aim of removing points corresponding to buildings; and (4) a new method based on a moving window, with longitudinal overlap between windows and transverse overlap between passes, is used to select the seed points. Our hybrid filtering method is tested using 15 reference samples acquired by the International Society of Photogrammetry and Remote Sensing (ISPRS) and is evaluated in comparison with 33 existing filtering algorithms. The results show that our hybrid filtering method produces an average total error of 3.34% and an average Kappa coefficient of 92.62%. The proposed algorithm is one of the most accurate filters that has been tested with the ISPRS reference samples.","2020-04","2025-05-05 17:07:58","2025-05-05 17:07:58","","NA","","7","12","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Later, during the analysis phase of the study, the researcher splits the recorded data trace into smaller sections, analyzes each section separately by finding a mean or fitting against a specified function, and uses the analysis results in the study. Here, we present the software that allows to analyze these data traces in a manner that ensures repeatability of the analysis and simplifies the application of FAIR (findability, accessibility, interoperability, and reusability) principles in such studies. At the same time, it simplifies the routine data analysis pipeline and gives access to a fast overview of the analysis results. For that, the software supports reading the raw data, processing the data as specified in the protocol, and storing all intermediate results in the laboratory database. The software can be extended by study- or hardware-specific modules to provide the required data import and analysis facilities. To simplify the development of the data entry web interfaces, that can be used to enter data describing the experiments, we released a web framework with an example implementation of such a site. The software is covered by open-source license and is available through several online channels. Author summary In biological and other types of experiments, we frequently record changes of some parameters in time or space. It is common to analyze the data by splitting the recording into smaller sections and relating it to some changes induced by the researchers. The steps involved in the analysis are: splitting of the data, fitting them to some function, relating the fit result to the change in the environment, and normalization. These steps are frequently done through several software packages, spreedsheets, and manual copy and paste between the programs. The software presented in this work allows to make all these analysis steps in one database in a manner that is easy, can be reproduced by others, and clearly tracks the history of all the analysis steps. In addition, it allows to link the experimental data with the description of the experiment, making it simple to perform tasks such as normalization of the recorded values, relating experimental recordings to the sample or animal, as well as extracting data from the laboratory database for publishing. The software is written to be easily extendable by user-defined modules to fit the analysis pipelines and is expected to improve the data analysis practices in research.","2020-12","2025-05-05 17:07:59","2025-05-05 17:07:59","","NA","","12","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The scientific literature presents several techniques that can be used to recognize the user's emotional state. However, many techniques involve the use of sensors that can result in financial costs and cause discomfort to the user. In this scenario, the recognition of the emotional state through the analysis of facial expressions presents itself as a useful and practical approach, since it does not involve the use of sensors attached to the user's body and executed in different types of devices. Despite these advantages, software that allow the analysis of facial expressions for free are still incipient, and performance evaluation of this type of software usually is not available. In order to contribute to this context and assist researchers who need this type of software, this study presents a comparative analysis of two open-source emotion recognition software (”CLMTrackr” and “Face-api.js”) simulating different environmental conditions related to lighting and distance. Considering images from two datasets, we generate 8675 videos simulating 25 different environmental conditions.

This difference can affect the fixing process of vulnerabilities. By mining the repositories of 6 open source projects, we characterize the differences in the fixing process between vulnerabilities and canonical bugs, highlighting critical issues which could represent challenges for future research. Results of our study demonstrate that: (i) more re-assignments (than the ones observed in canonical bugs) are required for finding the developers able to handle vulnerability-related bugs, (ii) developers' security-related skills should be profiled, to improve the efficiency of the security bug assignment tasks, and, consequently, reduce the re-assignments, and (iii) vulnerabilities require more effort, contributors and time to define the fixing strategy but smaller time to fix than canonical bugs.

In this study, we investigate and illustrate how OSS contributors accomplish large-scale refactoring in OSS development in which there is no significant corporate participation. In our observations, as the costs of coordination requirements rise, OSS contributors increase coordination capability to manage dependencies among multiple sources during the large-scale refactoring periods. Our findings suggest that OSS contributors episodically use traditional coordination mechanisms during the large-scale refactoring periods. Our study provides actionable insights into how OSS contributors make joint action that cannot be achieved by individuals working independently and use the provision of rewards in order to achieve a shared, explicit goal of large-scale refactoring.","2020","2025-05-05 17:08:03","2025-05-05 17:08:03","","150–184","","2","2","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; online communities; open source; Open source; coordination; Open-source software; Coordination; Software development; Public domain; Code refactoring; collaborative work; Reward; software refactoring; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Recent studies identified a variety of community smells and defined them as sub-optimal patterns connected to organizational-social structures in the software development community. To early detect and discover existence of potential community smells in a software project, we introduce, in this paper, a novel machine learning-based detection approach, named CSDETECTOR, that learns from various existing bad community development practices to provide automated support in detecting such community smells. In particular, our approach learns from a set of organizational-social symptoms that characterize the existence of potential instances of community smells in a software project. We built a detection model using Decision Tree by adopting the C4.5 classifier to identify eight commonly occurring community smells in software projects. To evaluate the performance of our approach, we conduct an empirical study on a benchmark of 74 open source projects from Github. Our statistical results show a high performance of CSDETECTOR, achieving an average accuracy of 96% and AUC of 0.94. Moreover, our results indicate that the CSDETECTOR outperforms two recent state-of-the-art techniques in terms of detection accuracy. Finally, we investigate the most influential community-related metrics to identify each community smell type. We found that the number of commits and developers per time zone, the number of developers per community, and the social network betweenness and closeness centrality are the most influential community characteristics.

Existing software tools enable characterizing and measuring the amount of technical debt at selective granularity levels; by providing a computational model, they enable stakeholders to measure and ultimately control this phenomenon. Aims: In this paper we aim to study the evolution and characteristics of technical debt in open-source software. For this, we carry out a longitudinal study that covers the entire development history of several complex applications. The goal is to improve our understanding of how the amount and composition of technical debt changes in evolving software. We also study how new technical debt is introduced in software, as well as identify how developers handle its accumulation over the long term. Method: We carried out our evaluation using three complex, open-source Java applications. All 110 released versions, covering more than 10 years of development history for each application were analyzed using SonarQube. We studied how the amount, composition and history of technical debt changed during development, compared our results across the studied applications and present our most important findings. Results: For each application, we identified key versions during which large amounts of technical debt were added, removed or both. This had significantly more impact when compared to the lines of code or class count increases that generally occurred during development. However, within each version, we found high correlation between file lines of code and technical debt. We observed that the Pareto principle was satisfied for the studied applications, as 20% of issue types generated around 80% of total technical debt. Interestingly, there was a large degree of overlap between the issues that generated most of the debt across the studied applications. Conclusions: Early application versions showed greater fluctuation in the amount of existing technical debt. We found application size to be an unreliable predictor for the quantity of technical debt. Most debt was introduced in applications as part of milestone releases that expanded their feature set; likewise, we identified releases where extensive refactoring significantly reduced the level of debt. We also discovered that technical debt issues persist for a long time in source code, and their removal did not appear to be prioritized according to type or severity.","2020","2025-05-05 17:08:06","2025-05-05 17:08:06","","NA","","NA","NA","","","","ESEM '20","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450375801 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","software evolution; open-source; software maintenance; static analysis; technical debt","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we propose a multiplex bipartite network ranking model, M-BiRank, to co-rank developers and projects using multiple developer-project interactions. Firstly, multiple developer-project interactions such as commit, issue, and watch are extracted and a multiplex developer-project bipartite network is constructed. Secondly, a random layer is selected from this multiplex bipartite network and initial ranking scores are calculated for developers and projects using BiRank. Finally, initial ranking scores diffuse to other layers and mutual reinforcement is taken into consideration to iteratively calculate ranking scores of developers and projects in different layers. Experiments on real-world GitHub dataset show that M-BiRank outperforms degree centrality, traditional single layer ranking methods, and multiplex ranking method.","2020-10-27","2025-05-05 17:08:06","2025-05-05 17:08:06","","NA","","1","2020","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This perspective implicitly assumes that accessed network knowledge automatically gets absorbed and transferred to projects, so that building more and deeper network connections is beneficial: Drawing from an absorptive capacity perspective, this research challenges such conventional wisdom, arguing instead that the benefits depend on a project's absorptive capacity. Network connections provide access to external knowledge in the community; the absorption and transfer of this new knowledge require appropriate internal knowledge and developer roles. With longitudinal data collected from 4,518 open source software development projects hosted at Source-Forge, the authors show that knowledge breadth (depth) helps with the absorption of external knowledge achieved from network depth (breadth), but it inhibits the absorption of external knowledge obtained from network breadth (depth). Further, developer roles (e.g., bridge members, role diversity) can mitigate the negative consequences of suboptimal combinations and facilitate effective transfers of absorbed external knowledge across and within projects. These findings provide important theoretical and managerial implications for managing network connections, knowledge, and developer roles in open source software communities.","2020-12","2025-05-05 17:08:09","2025-05-05 17:08:09","","1651-1678","","4","44","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Open source; Knowledge; Knowledge management; Social networks; Software development; Public domain; Network effect; Absorption; Absorptive capacity; Absorptivity; Knowledge acquisition; Knowledge community","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity. (C) 2019 The Authors.

Many individuals and organizations have purchased consumer-grade UAVs, and commonly acquire aerial photographs to map land cover. The resulting ultra-high-resolution (sub-decimeter-resolution) imagery has high information content, but automating the extraction of this information to create accurate, wall-to-wall land-cover maps is quite difficult. We introduce image-processing workflows that are based on open-source software and can be used to create land-cover maps from ultra-high-resolution aerial imagery. We compared four machine-learning workflows for classifying images. Two workflows were based on random forest algorithms. Of these, one used a pixel-by-pixel approach available in ilastik, and the other used image segments and was implemented with R and the Orfeo ToolBox. The other two workflows used fully connected neural networks and convolutional neural networks implemented with Nenetic. We applied the four workflows to aerial photographs acquired in the Great Basin (western USA) at flying heights of 10 m, 45 m and 90 m above ground level. Our focal cover type was cheatgrass (Bromus tectorum), a non-native invasive grass that changes regional fire dynamics. The most accurate workflow for classifying ultra-high-resolution imagery depends on diverse factors that are influenced by image resolution and land-cover characteristics, such as contrast, landscape patterns and the spectral texture of the land-cover types being classified. For our application, the ilastik workflow yielded the highest overall accuracy (0.82-0.89) as assessed by pixel-based accuracy.","2020-12","2025-05-05 17:08:10","2025-05-05 17:08:10","","487-497","","4, SI","6","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To bridge this gap, we undertook a large-scale data-driven study to understand how decisions are made in an OSSD community, using the case study of Python Enhancement Proposals (PEPs), which embody decisions made during the evolution of the Python language.

Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been in-stitutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous se-curity in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed secu-rity controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption en-ables businesses to deliver time-to-market security ready applications and services with accelerated ve-locity and sustainable agility in a cost-effective way.

This model is a liquid-solid mixture model inspired from the pioneer work of Bennon and Incropera, including mass, momentum, energy and species conservation equations. In particular, the energy conservation equation is formulated with the temperature variable, the thermosolutal convection is accounted for through the Boussinesq approximation and the interdendritic flow in the mushy zone is governed by the Darcy's law. Furthermore, a rigid solid phase is assumed and classical microsegregation models are used featuring lever-rule or Gulliver-Scheil assumptions. At the discrete level, a first-order upwind scheme is implemented with a SIMPLEC approach to solve the velocity-pressure coupling. The other couplings involving temperature and concentration fields are efficiently solved performing sub-loops with a PISO-like approach. The overall scheme is mainly implicit with additional treatments to ensure the equilibrium between the hydrostatic pressure gradient and the buoyant forces, and to deal properly with solid zones. The segregation predictions offered by the model are validated against both academic test case and industrial ingot configurations. A convergence study is also led focusing on time step and mesh size sensitivities.","2020","2025-05-05 17:08:13","2025-05-05 17:08:13","","NA","","NA","861","","","","IOP Conference Series-Materials Science and Engineering","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While intra-operative ultrasound (iUS) guidance has shown clear potential to reduce surgery time, compared with clinical computed tomography (CT) guidance, rapid registration aiming to correct for patient misalignment has not been addressed. In this article, we present an open-source platform for pedicle screw navigation using iUS imaging. The alignment method is based on rigid registration of CT to iUS vertebral images and has been designed for fast and fully automatic patient re-alignment in the operating room. Two steps are involved: first, we use the iUS probe's trajectory to achieve an initial coarse registration; then, the registration transform is refined by simultaneously optimizing gradient orientation alignment and mean of iUS intensities passing through the CT-defined posterior surface of the vertebra. We evaluated our approach on a lumbosacral section of a porcine cadaver with seven vertebral levels. We achieved a median target registration error of 1.47 mm (100% success rate, defined by a target registration error <2 mm) when applying the probe's trajectory initial alignment. The approach exhibited high robustness to partial visibility of the vertebra with success rates of 89.86% and 88.57% when missing either the left or right part of the vertebra and robustness to initial misalignments with a success rate of 83.14% for random starts within +/- 20 degrees rotation and +/- 20 mm translation. Our graphics processing unit implementation achieves an efficient registration time under 8 s, which makes the approach suitable for clinical application.

In order to effectively promote the growth of online secondhand markets, this paper designs and validates a scale to assess customer perception of the service quality of secondhand products purchased via online platforms. Complementarily, the paper assesses how each of the different dimensions that configure the scale contributes to explaining the fulfillment of customers' expectations. The scale is defined by 23 items and is arranged in 5 dimensions from the literature on online commerce as well as on the sharing economy. A sample of 200 questionnaires is used for exploratory factor analysis. A second sample of 507 users is used for confirmatory factor analysis. The quality perceived by online customers of secondhand products depends on the quality of the interactions that they have with the website, with the vendor, and with the product. The dimension that contributes the most to customer fulfillment of expectations is product quality. Findings identify the items that contribute the most to quality perception and fulfillment of expectations, facilitating the development of more effective strategies for platform owners and vendors who want to attract and retain customers of secondhand products.

To estimate whether a state ofsocio-technical congruenceis achieved, which is associated with software quality and project success, we assess the alignment of collaboration and communication in such software projects in terms ofcoordination requirements. By means of an empirical study on a substantial set of large-scale open-source software projects-the development histories of all projects sum up to over 180 years-we aim at shedding light on this issue. To this end, to take a more semantic view on this phenomenon in comparison to previous work, we do not only identify coordination requirements arising from files and functions only, but also those arising from features. We found that open-source developers fulfill coordination requirements intentionally, but mostly those coordination requirements that arise from coupled source-code artifacts, while they resolve simpler ones independently. Furthermore, neither of the considered abstraction levels of source-code artifacts (files, functions, features) is more suitable to construct coordination requirements with respect to their fulfillment. This finding strongly indicates that features do not play an as important role in the development process as expected and commonly believed by the research community in the area of feature-oriented and feature-driven development. Finally, we identified notable evolutionary trends in the fulfillment of coordination requirements and showed that far-reaching social events (such as organizational issues) have a huge impact on their fulfillment, both negatively and positively. The key findings of our empirical study are that socio-technical relations are important to understand open-source development communities and that the incorporation of different abstraction levels for developer collaboration does yield important insights to further improve the evolution in open-source software projects.","2020-11","2025-05-05 17:08:15","2025-05-05 17:08:15","","4379-4426","","6","25","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER","","","","Socio-technical congruence; Codeface; Configurable systems; Coordination requirements; Coronet; Features; Software product lines; \n Social-network analysis; Feature-oriented\n software development; Open-source software\n systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Unlike traditional software development, OSS development is driven by collaboration among developers spread geographically and motivated by common goals and interests. Besides this fact, it is recognized by the OSS community the need to understand OSS development process and its activities. Our goal is to investigate the state-of-art about OSS process through conducting a systematic literature review providing an overview of how the OSS community has been investigating OSS process over past years. We identified and summarized OSS process activities and their characteristics and translated them into an OSS macro process using BPMN notation. As a result, we systematically analyzed 33 studies presenting an overview of the OSS process research and a generalized OSS development macro process represented by BPMN notation with a detailed description of each OSS process activity and roles in OSS environment. We conclude that OSS process can be in practice further investigated by researchers. In addition, the presented OSS process can be used as a guide for OSS projects and be adapted according to each OSS project reality. It provides insights to managers and developers who want to improve their development process even in OSS and traditional environments. Finally, recommendations for OSS community regarding OSS process activities are provided.","2020","2025-05-05 17:08:15","2025-05-05 17:08:15","","135-144","","NA","NA","","","","IEEE International Enterprise Distributed Object Computing\n Conference-EDOC","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 978-1-7281-6473-1 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Various thematic maps such as lithology/hydrogeology, soil, land-cover/use, slope, lineament density, drainage density and rainfall distribution were integrated in QGIS software. Vector input layers were rasterized and resampled using QGIS wrap projection function to make sure that the grid cells are of the same size. Reclassification using SAGA and GRASS reclass algorithms in QGIS was carried out to realign the factor classes in a consistent scale, and reclassification to a scale of 1 to 5 was carried out to harmonize the results. The study identified a number of potential areas for groundwater recharge, groundwater exploration, groundwater development and potential areas for artificial groundwater recharge. Potential groundwater recharge zones for the Singida semi-arid fractured aquifer are restricted to areas with high lineament density, cultivated areas, grassland and flat to gentle slopes. The potential of groundwater recharge is also observed in areas with low drainage density. The delineated zones provide a good understanding of the potential recharge zones, which are a starting point for recharge zone protection. This blended approach can be utilized for carrying out suitability analysis using the weighted overlay analysis approach. Areas designated good and very good are recommended for artificial recharging structures as an alternative technique for enhancing groundwater recharge through rainwater harvesting. This will help to augment groundwater storage in this semi-arid environment.","2020-06","2025-05-05 17:08:16","2025-05-05 17:08:16","","NA","","2","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Mass spectrometry (MS) is a versatile technique that is used to analyze a broad range of compounds from different species and cell-types, with high accuracy, resolution, sensitivity, selectivity, and fast data acquisition speeds. With recent advances in MS and spectroscopy-based platforms, the research community is able to generate high-throughput data sets from single cells.

In the hope of facilitating this exploration and promoting the reproducibility of geophysical simulations and inversions, we have developed the open-source software package SimPEG. The software has been designed to be modular and extensible, with the goal of allowing researchers to interrogate all of the components and to facilitate the exploration of new inversion strategies. We present an overview of the software in its application to airborne electromagnetics and demonstrate its use for visualising fields and fluxes in a forward simulation, as well as its flexibility in formulating and solving the inverse problem. We invert a line of airborne time-domain electromagnetic data over a conductive vertical plate using a 1D voxel inversion, a 2D voxel inversion and a parametric inversion, where all of the forward modelling is done on a 3D grid. The results in this paper can be reproduced using the provided Jupyter notebooks.

The proposed approach i) embeds the historical programming behavior data of a project into a multi-dimensional vector space to capture the potential laws in the data, ii) forms an eigenvector matrix reflecting the semantic relationship of the development behavior data, and predicts the next programming behavior of a specific developer based on the eigenvector matrix. Our experiments on five OSS projects show that the prediction accuracy rate of the proposed prediction approach can reach up to about 50%, indicating that it can summarize the development behavior data law and effectively predict the programming behavior of developers.

The PCA denoising method is applied to ten scans of EBSPs from the same region of interest of a recrystallised nickel sample acquired with a decreasing S/N, achieved by reducing the exposure time while increasing the camera gain accordingly. That PCA denoising increases S/N in EBSPs is demonstrated by comparing indexing success rates after both Hough and dictionary indexing (HI and DI) of the Ni patterns having undergone one of four processing routes: i) standard static and dynamic background corrections (standard corrections), ii) standard corrections and pattern averaging with the four closest neighbours, iii) standard corrections and PCA denoising, and iv) standard corrections and pattern averaging followed by PCA denoising. Both pattern averaging and PCA denoising increases the indexing success rates for both indexing approaches for the studied Ni scans, with the former processing route providing the better success rates. The best success rates are obtained after pattern averaging followed by PCA denoising. The potential of PCA denoising to reveal additional pattern details compared to standard corrections and pattern averaging is demonstrated in a pattern from an orthoclase (KAlSi3O8) grain in a geological sample.

ResIPy was developed to provide a more intuitive, user-friendly, approach to inversion of geoelectrical data, using an open source graphical user interface (GUI) and a Python application programming interface (API). ResIPy utilizes the mature R2/cR2 inversion codes for ERT and IP, respectively. The ResIPy GUI facilitates data importing, data filtering, error modeling, mesh generation, data inversion and plotting of inverse models. Furthermore, the easy to use design of ResIPy and the help provided inside makes it an effective educational tool.

For every type of application, there are a wide variety of alternatives. We observed that even if different applications that perform similar tasks and compiled with the same versions of the compiler and the libraries, they perform very differently while running on the same system. Sadly prior work in this area that compares two code bases for similarities does not help us in finding the reasons for the differences in performance. In this paper, we develop a tool, SoftMon, that can compare the codebases of two separate applications and pinpoint the exact set of functions that are disproportionately responsible for differences in performance. Our tool uses machine learning and NLP techniques to analyze why a given open-source application has a lower performance as compared to its peers, design bespoke applications that can incorporate specific innovations (identified by SoftMon) in competing applications, and diagnose performance bugs. In this paper, we compare a wide variety of large open-source programs such as image editors, audio players, text editors, PDF readers, mail clients and even full-fledged operating systems (OSs). In all cases, our tool was able to pinpoint a set of at the most 10-15 functions that are responsible for the differences within 200 seconds. A subsequent manual analysis assisted by our graph visualization engine helps us find the reasons. We were able to validate most of the reasons by correlating them with subsequent observations made by developers or from existing technical literature. The manual phase of our analysis is limited to 30 minutes (tested with human subjects).","2020","2025-05-05 17:08:24","2025-05-05 17:08:24","","397-408","","NA","NA","","","","IEEE International Working Conference on Mining Software Repositories","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software\n Engn; ACM Special Interest Grp Software Engn; Korean Inst Informat\n Scientists & Engineers ISBN: 978-1-4503-7517-7 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","NLP based matching; Performance debugging; Software comparison","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

National user groups can bolster these international communities by convening local events, championing the software to peers, welcoming and onboarding new contributors, raising money to support the broader community, and collecting important information on user's needs. The open source community-led software DSpace has had great success encouraging the creation of national user groups; in the UK, North America, and Germany, the Groups have been active for many years. However, it was in 2018, thanks to a renewed focus on international engagement and more diverse representation of the global community in governance groups, that the national communities entered into a new phase: 15 new national User Groups have been formed all over the world since then, while the German user group evolved into the “DSpace-Konsortium Deutschland”, founded by 25 institutions, marking a pivotal point for membership options and National User Group participation within DSpace Governance. This article will offer an overview of the historical development of the DSpace community and its governance model, as well as DuraSpace's international engagement strategy, including its benefits and challenges.

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.","2020-09","2025-05-05 17:08:25","2025-05-05 17:08:25","","1439-1458","","3","44","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: UNIV MINNESOTA-SCH MANAGEMENT 271 19TH AVE SOUTH, MINNEAPOLIS, MN 55455\n USA Publisher: SOC INFORM MANAGE-MIS RES CENT","","","","Open source software; product quality; signaling; takeoff","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It allows the creation of live loads, and these are used in calculating the envelope of internal forces in bridge beams. Despite this, a significant number of projects, dissertations and theses in the area of bridges, especially in graduate courses, still do not use it in the analysis of life loads in bridge beams. In this sense, this project aims to encourage the use of Ftool to carry out structural analysis in beams of bridge beams, whether in determining the respective lines of influence or internal efforts; so that graduate students and researchers start to use it in their respective projects. Four numerical examples are developed and each one uses paid software, SAP2000, Ansys or GAP-GEL v1, and the results are compared with Ftool. In all examples, the variations in the results are less than 9%, in the worst case, but in most of them, this variation is less than 3%. These differences can be considered as acceptable, since, later, different coefficients are applied. Finally, the Ftool proved to be effective and robust, with reliable results and, therefore, recommended for the determination of the different internal and TTL efforts in the beams, due to different live loads acting on bridge decks composed of two, three, seven and eight beams. Without the need to use more complex and paid software to carry out such analyzes.","2020","2025-05-05 17:08:25","2025-05-05 17:08:25","","NA","","3","36","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for-profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a “Third Design Space,” based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.","2020-03","2025-05-05 17:08:27","2025-05-05 17:08:27","","369-402","","2","30","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","software development; open source software; metaphor; postcolonialism; third space; \n Third Design Space","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Open platforms and managers face a challenging design choice in deciding whether to allow APC and for which tasks or what type of projects. We examine the impact that the ratio between APC and IPC has on OSS project performance. Our results suggest that the OSS projects perform the best when they contain a uniform anonymity level (i.e., they contain predominantly APC or predominantly IPC).

However, with the emergence of new environmental design tasks, addressing all possible use cases and tasks is challenging and cannot be covered by a single tool. Urban-scale analysis at this level of complexity often requires linking multiple emerging tools, rather than using a single tool, to adequately evaluate a variety of possible fields in urban environmental design. To achieve this, flexible platforms are needed to support multiple input formats (e.g., geometric and non-geometric building properties), enabling the mapping of such inputs to underlying simulation engines. This paper provides an overview of the open-source URBANopt Software Development Kit (SDK) for modeling high-performance buildings and energy systems at a district scale. URBANopt's flexible SDK is composed of several modules that can be customized to integrate with other tools and generate new workflows to perform urban environmental design tasks, such as capturing interactions between individual buildings, district energy systems, distributed energy resources, and the electric distribution grid. We describe the functionality of the core SDK modules in URBANopt (called Core Gem, GeoJSON Gem, and Scenario Gem) and discuss the flexibility of these modules as a means of integration with a variety of tools. We also document and demonstrate technical details of writing and combining new modules to create customized workflows. Finally, we present a case study that uses the URBANopt SDK to model a hypothetical mixed-use urban project and simulate various scenarios to meet district energy performance goals.","2020","2025-05-05 17:08:31","2025-05-05 17:08:31","","293-301","","NA","NA","","","","ASHRAE/IBPSA-USA Building Simulation Conference","","","","","","NA","","","","","","","Backup Publisher: ASHRAE; IBPSA USA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed “episodic volunteering” (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature. Also, episodic volunteers make a wide range of value-added contributions other than code, and they should neither be expected nor coerced into becoming habitual volunteers.","2020-09-01","2025-05-05 17:08:31","2025-05-05 17:08:31","","962-980","","9","46","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC","","","","Open source software; free software; Community management; Companies; Sustainable development; Lenses; episodic volunteering; peripheral developer; \n open source software; Task\n analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It also examines the validity of UTAUT in the open source software context. Quantitative design has been used following the distribution of questionnaire among a sample of 255 individuals employed at public and private organizations (172 males and 83 females).

An abundant amount of effort has been put by the research community to develop software maintainability prediction (SMP) models by relating software metrics to the maintainability of modules or classes. When software classes demanding the high maintainability effort (HME) are less as compared to the low maintainability effort (LME) classes, the situation leads to imbalanced datasets for training the SMP models. The imbalanced class distribution in SMP datasets could be a dilemma for various ML techniques because, in the case of an imbalanced dataset, minority class instances are either misclassified by the ML techniques or get discarded as noise. The recent development in predictive modeling has ascertained that ensemble techniques can boost the performance of ML techniques by collating their predictions. Ensembles themselves do not solve the class-imbalance problem much. However, aggregation of ensemble techniques with the certain techniques to handle class-imbalance problem (e.g., data resampling) has led to several proposals in research. This paper evaluates the performance of ensembles for the class-imbalance in the domain of SMP. The ensembles for class-imbalance problem (ECIP) are the modification of ensembles which pre-process the imbalanced data using data resampling before the learning process. This study experimentally compares the performance of several ECIP using performance metrics Balance and g-Mean over eight Apache software datasets. The results of the study advocate that for imbalanced datasets, ECIP improves the performance of SMP models as compared to classic ensembles.","2020-10","2025-05-05 17:08:33","2025-05-05 17:08:33","","NA","","5, SI","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: Univ Delhi, Dept Operat Res; Soc Reliabil Engn Qual & Operat Management ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. “simple”, intermediate” or “complex”, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.","2020-07-15","2025-05-05 17:08:33","2025-05-05 17:08:33","","NA","","NA","266","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 24-28 OVAL RD, LONDON NW1 7DX, ENGLAND Publisher: ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD","","","","Remote sensing; Cover estimation; Ecological monitoring; Guidos toolbox; Morphological spatial pattern analysis; Invasive alien\n species","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To gain the potential benefits, an organization may need to consider what they share and how, while taking into account risks, costs and other complexities. Objective: This study aims to empirically investigate objectives and complexities organizations need to consider and balance between when deciding on what software to share as OSS, when to share it, and whether to create a new or contribute to an existing community. Method: A multiple-case study of three case organizations was conducted in two research cycles, with data gathered from interviews with 20 practitioners from these organizations. The data was analyzed qualitatively in an inductive and iterative coding process. Results: 12 contribution objectives and 15 contribution complexities were found. Objectives include opportunities for improving reputation, managing suppliers, managing partners and competitors, and exploiting externally available knowledge and resources. Complexities include risk of loosing control, risk of giving away competitive advantage, risk of creating negative exposure, costs of contributing, and the possibility and need to contribute to an existing or new community. Conclusions: Cross-case analysis and interview validation show that the identified objectives and complexities offer organizations a possibility to reflect on and adapt their contribution strategies based on their specific contexts and business goals.","2020-09","2025-05-05 17:08:35","2025-05-05 17:08:35","","3799-3840","","5","25","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The effect of gender diversity in open source communities has gained increasing attention from practitioners and researchers. For instance, organizations such as the Python Software Foundation and the OpenStack Foundation started actions to increase gender diversity and promote women to top positions in the communities. Problem. Although the general underrepresentation of women (a.k.a. horizontal segregation) in open source communities has been explored in a number of research studies, little is known about the vertical segregation in open source communities—which occurs when there are fewer women in high level positions. Aims. To address this research gap, in this paper we present the results of a mixed-methods study on gender diversity and work practices of core developers contributing to open-source communities. Method. In the first study, we used mining-software repositories procedures to identify the core developers of 711 open source projects, in order to understand how common are women core developers in open source communities and characterize their work practices. In the second study, we surveyed the women core developers we identified in the first study to collect their perceptions of gender diversity and gender bias they might have observed while contributing to open source systems. Results. Our findings show that open source communities present both horizontal and vertical segregation (only 2.3% of the core developers are women). Nevertheless, differently from previous studies, most of the women core developers (65.7%) report never having experienced gender discrimination when contributing to an open source project. Finally, we did not note substantial differences between the work practices among women and men core developers. Conclusions. We reflect on these findings and present some ideas that might increase the participation of women in open source communities.","2020","2025-05-05 17:08:35","2025-05-05 17:08:35","","NA","","NA","NA","","","","ESEM '20","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450375801 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Core Developer; Gender Diversity; OSS Community; Vertical Segregation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A typical procedure to create 3D printed splints is obtaining the geometry of a body segment using a 3D scanner, creating a 3D printable splint model based on the geometry of the body segment, and 3D printing the splint. As technologies of 3D scanning and 3D printing become mature gradually, the main challenge to fabricate 3D printed splint is to create 3D printable splint models. To solve this challenge, researchers have proposed various methods to design 3D splint models. However, most methods require extensive 3D modeling skills that medical professionals are lacking. In this work, a semi-automatic method is proposed to create a 3D printable model. Given the geometry of a body segment obtained through a 3D scanner, the method includes three key steps: (1) create a draft splint lattice structure, (2) optimize the splint structure, and (3) create a 3D printable model based on the optimized structure. All the software adopted for this method is free and readily available, and thus, there is no additional cost to convert from a scanned geometry of a body segment to a 3D printable splint model. Because the majority of the work is done automatically, with initial training, a medical professional should be able to create a 3D printable model using the proposed method, given the geometry of a body segment. The proposed method is demonstrated by creating a 3D printed wrist splint and the demo is uploaded into GitHub, a popular open-source platform.","2021-03-16","2025-05-05 17:08:36","2025-05-05 17:08:36","","NA","","3","13","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We focused our examination on released versions, resulting in 111 software releases included in our case study. These covered more than 10 years of development for each of the applications. For each version, we determined its maintainability using three distinct quantitative models of varying complexity. We examined the relation between software size and maintainability and studied the main drivers of important changes to software maintainability. We contextualized our findings using manual source code examination.

Global action plans to address non-communicable diseases (NCDs) recognise the centrality of community engagement to create an enabling environment within which to address risk factors. Study design: In this article, we describe and critically reflect on a cocreated community engagement approach to address type 2 diabetes in the southern plains of Nepal. We coproduced the engagement approach with 40 artists from the Janakpur Women's Development Centre to create an environment for dialogue about diabetes and NCD risk between artists and the general public. Methods: We used participatory action research to produce contextually relevant interactive methods and materials. Methods included artists' peer research to inform creative workshops, a drama performed in 19 villages and a two-day funfair in a public park. We used qualitative and participatory methods to analyse the effect of this engagement and reflect on lessons learned. Results: Around 2000 people saw the drama, and around 4000 people attended the funfair. Community dialogue about prevention of diabetes was facilitated by drama and through games and songs at the funfair. Artists grew confident to interact with their peers and drama audiences about the causes of diabetes and prevention strategies. Despite crowds at the funfair, it was difficult to reach women because the venue was often used by men and boys, and patriarchal norms prevent women from free movement. Village interactions were able to engage a more mixed audience. Conclusion: Innovative, asset-based community engagement about diabetes and other NCDs at scale is possible through locating, building on and strengthening community resources to address local health issues. Engagement could be enhanced by considering the gendered nature of community engagement spaces and by increasing opportunities for interaction between artists and the general public through more intimate and large-scale events.

Taking imatinib (IMA) as an example, we developed an efficient workflow to describe IMA biodegradation with activated sludge (AS) from wastewater treatment plants (WWTP). IMA is a cytostatic pharmaceutical; a selective tyrosine kinase inhibitor used to treat chronic myeloid leukemia. Its reported ecotoxic, endocrine and genotoxic effects imply high risk for aquatic wildlife and human health, however its fate in the environment is not yet well known. The study was conducted in a batch biotransformation setup, at two AS concentration levels and in presence and absence of carbon source. Degradation profiles and formation of IMA transformation products (TPs) were investigated using UHPLC-QqOrbitrap-MS/MS which showed that IMA is readily biodegradable. TPs were determined using multivariate statistical analysis. Eight TPs were determined and tentatively identified, six of them for first time. Hydrolysis of amide bond, oxidation, demethylation, deamination, acetylation and succinylation are proposed as major biodegradation pathways. TP235, the product of amide bond hydrolysis, was detected and quantified in actual wastewaters, at levels around 1 ng/L. This calls for more studies on the environmental fate of IMA in order to properly asses the environmental risk and hazard associated to IMA and its TPs. (c) 2021 The Authors.

Using a conventional protocol to fabricate IHS from casts of the initial situation or the wax-up can be challenging, time-consuming, and sometimes frustrating. A digital workflow makes this process quicker and more convenient. The IHS must be first designed with computer-aided design (CAD), then fabricated with computer-aided manufacture (CAM). Proprietary dental software is commonly used for the design process but needs to be purchased. Objective: To describe a step-by-step technique for designing an IHS for posterior relining with open-source software. Methods: This paper describes a straightforward procedure to design an IHS from a dental scan of the initial situation or a digital wax-up for an esthetic and functional temporary rehabilitation. Results: An IHS can be quickly designed using open-source software by copying an existing restoration or a conventional or digital wax-up. Then, the design can be 3D printed using a biocompatible resin. Conclusions: The clinician can use open-source software to design IHSs, which are then 3D printed using a biocompatible resin.

Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system's sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries.

Research on this ecosystem is scarce and research on the ecosystem health is non-existent, even though ecosystem health is an useful indicator of the livelihood of an ecosystem. The goal of this research is to evaluate the health of the ecosystem through an assessment of Tor, I2P and GitHub. The Open Source Ecosystem Health Operationalization framework is used to help perform this assessment. Eight metrics from the framework are selected, which are measured using the data collected. Analysis of Tor and I2P metrics suggest that there has been an increase in Tor and I2P user activity in the recent past. Added knowledge, spin offs and forks and usage indicate active participation and interest in Tor and I2P. There has also been an increase in the number of active GitHub Dark Web projects. However, these GitHub projects are not well-connected and only a small number of projects have a large number of contributors. There is some variety among the GitHub software projects.

CRIMSON provides a powerful, customizable and user-friendly system for performing three-dimensional and reduced-order computational haemodynamics studies via a pipeline which involves: 1) segmenting vascular structures from medical images; 2) constructing analytic arterial and venous geometric models; 3) performing finite element mesh generation; 4) designing, and 5) applying boundary conditions; 6) running incompressible Navier-Stokes simulations of blood flow with fluid-structure interaction capabilities; and 7) post-processing and visualizing the results, including velocity, pressure and wall shear stress fields. A key aim of CRIMSON is to create a software environment that makes powerful computational haemodynamics tools accessible to a wide audience, including clinicians and students, both within our research laboratories and throughout the community. The overall philosophy is to leverage best-in-class open source standards for medical image processing, parallel flow computation, geometric solid modelling, data assimilation, and mesh generation. It is actively used by researchers in Europe, North and South America, Asia, and Australia. It has been applied to numerous clinical problems; we illustrate applications of CRIMSON to real-world problems using examples ranging from pre-operative surgical planning to medical device design optimization. Author summary We provide the first full presentation in the literature of CRIMSON, the Cardiovascular Integrated Modelling and Simulation Package. CRIMSON consists of a graphical user interface desktop computer program for creating geometric models of blood vessels from medical imaging scans, specifying parameters such as the stiffness of the artery walls, the resistance of connected vessels which are not visible on the scans, and determining the appropriate parameters for all aspects of the model. CRIMSON additionally consists of the Flowsolver, a high-performance computing package which simulates the flow of blood through the models created in the graphical user interface. Whilst several packages which can simulate blood flow exist, most target general fluid simulations, and this lack of specialisation means that blood flow simulation is harder to perform, and can require ad hoc (and potentially scientifically-limiting) workflow decisions. CRIMSON's specialisation deals with these problems, as well as presenting a number of unique features which are unavailable elsewhere.","2021-05","2025-05-05 17:08:38","2025-05-05 17:08:38","","NA","","5","17","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this context, the present study has analyzed the factors that incentivize OSS implementations for enterprise purposes, linking two perspectives: (1) managerial and (2) educational. Thus, the Delphi methodology was applied to a panel of experts with two aims: (1) to know managers' perceptions about organizational users' motivations toward OSS after receiving OSS training and (2) to develop a forecasting study to examine the OSS diffusion in the medium term in companies and educational centers. In this context, the Self-Determination Theory (SDT) was the theoretical approach through which we identified the motivational factors. Specifically, three SDT motivations were added: (1) autonomy, (2) competence and (3) relatedness. The 104 selected experts were managers from companies with employees who have studied in educational centers where OSS usage is mandatory. The results show that managers perceive that OSS training incentivizes OSS implementations in companies. At the same time, user motivations are considered to be extremely relevant, especially autonomy. In addition, is the results foresee a similar level of OSS implementation in the business and educational fields in the medium term.

Motile cilia move fluid flow or propel cells, while also fulfill sensory functions. Primary cilia are immotile and act as a cellular antenna, translating environmental cues into cellular responses. Ciliary dysfunction leads to severe diseases, commonly termed ciliopathies. The molecular details underlying ciliopathies and ciliary function are, however, not well understood. Since cilia are small subcellular compartments, imaging-based approaches have been used to study them. However, tools to comprehensively analyze images are lacking. Automatic analysis approaches require commercial software and are limited to 2D analysis and only a few parameters. The widely used manual analysis approaches are time consuming, user-biased, and difficult to compare. Here, we present CiliaQ, a package of open-source, freely available, and easy-to-use ImageJ plugins. CiliaQ allows high-throughput analysis of 2D and 3D, static or time-lapse images from fluorescence microscopy of cilia in cell culture or tissues, and outputs a comprehensive list of parameters for ciliary morphology, length, bending, orientation, and fluorescence intensity, making it broadly applicable.

Clinica aims for researchers to (i) spend less time on data management and processing, (ii) perform reproducible evaluations of their methods, and (iii) easily share data and results within their institution and with external collaborators. The core of Clinica is a set of automatic pipelines for processing and analysis of multimodal neuroimaging data (currently, T1-weighted MRI, diffusion MRI, and PET data), as well as tools for statistics, machine learning, and deep learning. It relies on the brain imaging data structure (BIDS) for the organization of raw neuroimaging datasets and on established tools written by the community to build its pipelines. It also provides converters of public neuroimaging datasets to BIDS (currently ADNI, AIBL, OASIS, and NIFD). Processed data include image-valued scalar fields (e.g., tissue probability maps), meshes, surface-based scalar fields (e.g., cortical thickness maps), or scalar outputs (e.g., regional averages). These data follow the ClinicA Processed Structure (CAPS) format which shares the same philosophy as BIDS. Consistent organization of raw and processed neuroimaging files facilitates the execution of single pipelines and of sequences of pipelines, as well as the integration of processed data into statistics or machine learning frameworks. The target audience of Clinica is neuroscientists or clinicians conducting clinical neuroscience studies involving multimodal imaging, and researchers developing advanced machine learning algorithms applied to neuroimaging data.","2021-08-13","2025-05-05 17:08:38","2025-05-05 17:08:38","","NA","","NA","15","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study describes the conversations around adopting and crafting a code of conduct as well as those utilizing code of conduct for community governance. We conduct a qualitative analysis of a random sample of GitHub issues that involve the code of conduct. We find that codes of conduct are used both proactively and reactively to govern community behavior in project issues. Oftentimes, the initial addition of a code of conduct does not involve much community participation and input. However, a controversial moderation act is capable of inciting mass community feedback and backlash. Project maintainers balance the tension between disciplining potentially offensive forms of speech and encouraging broad and inclusive participation.

Mapping the surface patterns of stone is a non-destructive procedure critical for the qualitative and quantitative rating of the preservation state. Furthermore, mapping is employed for the annotation of weathering categories and the calculation of damage indexes. However, it is often a time-consuming task, which is conducted manually. Thus, practical methods need to be developed to automatize degradation mapping without significantly increasing the diagnostic process's cost for conservation specialists. This work aims to develop and evaluate a methodology based on affordable close-range sensing techniques, image processing, and free and open source software for the spatial description, annotation, qualitative analysis, and rating of stone weathering-induced damage. Low-cost cameras were used to record images in the visible, near-infrared, and thermal-infrared spectra. The application of photogrammetric techniques allowed for the generation of the necessary background, that was elaborated to extract thematic information.

Despite extensive research on commercial participation in OSS, the exact nature and extent of company contributions to OSS development, and the impact of this engagement may have on the volunteer community have not been clarified. To bridge the gap, we perform an exploratory study of OpenStack: a large OSS ecosystem with intense commercial participation. We quantify companies' contributions via the developers that they provide and the commits made by those developers. We find that companies made far more contributions than volunteers and the distribution of the contributions made by different companies is also highly unbalanced. We observe eight unique contribution models based on companies' commercial objectives and characterize each model according to three dimensions: contribution intensity, extent, and focus. Companies providing full cloud solutions tend to make both intensive (more than other companies) and extensive (involving a wider variety of projects) contributions. Usage-oriented companies make extensive but less intense contributions. Companies driven by particular business needs focus their contributions on the specific projects addressing these needs.

Results The amount of bone resorption in the Bio-Oss (R)-treated group was 25.2%, whereas that of the Cytrans (R)-treated group was 14.2%. A significant difference was found between the two groups (P < 0.001). Conclusions Our findings indicate that the volume of bone resorption was smaller in the Cytrans (R)-treated group than in the Bio-Oss (R)-treated group, suggesting that Cytrans (R) is more promising for successful implant treatments requiring a sinus lift.","2021-03-23","2025-05-05 17:08:39","2025-05-05 17:08:39","","NA","","1","7","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: SHIROYAMA TRUST TOWER 5F, 4-3-1 TORANOMON, MINATO-KU, TOKYO, 105-6005,\n JAPAN Publisher: SPRINGER JAPAN KK","","","","CBCT; Cone-beam computed tomography; Maxillary sinus augmentation; Sinus lift; \n Dental implant; Bio-Oss&\#174; Cytrans&\#174","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-player game and examine how open-source licensing affects competition among an open-source originator, an open-source contributor, and a proprietor competing in an enterprise software market. In this regard, we examine (1) how quality investments and prices are endogenously determined in equilibrium, (2) how license restrictiveness impacts equilibrium investments and the quality of offerings, and (3) how license restrictiveness affects consumer surplus and social welfare. Although some in the open-source community often advocate restrictive licenses such as theGNUGeneral Public License because it is not always in the best interest of the originator for the contributor to invest greater development effort, such licensing can actually be detrimental to both consumer surplus and social welfare when it exacerbates this incentive conflict. We find such an outcome in markets characterized by software providers with similar development capabilities yet cast in favor of the proprietor. In contrast, when these capabilities either become more dispersed or remain similar but tilt in favor of open source, a more restrictive license instead encourages greater effort from the OSS contributor, leads to higher OSS quality, and provides a larger societal benefit.","2021-05","2025-05-05 17:08:39","2025-05-05 17:08:39","","3041-3066","","5","67","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Software; Open-source software; Licenses; Incentives; Companies; Competition; Game theory; Markets; Public domain; Licensing; Prices; Best interests; Economic value added; Equilibrium; Social welfare; Business And Economics–Labor And Industrial Relations","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These tests have also proved useful to assess the non-motor symptoms in the animal models of movement disorders such as Parkinson's disease and Huntington's disease. Manual analysis of FST and TST is a time-consuming exercise and has large observer-to-observer variability. Automation of behavioral analysis alleviates these concerns, but there are no easy-to-use open-source tools for such analysis. Here, we describe the development of Depression Behavior Scorer (DBscorer), an open-source program installable on Windows, with an intuitive graphical user interface (GUI), that helps in accurate quantification of immobility behavior in FST and TST from video analysis. Several calibration options allow customization of various parameters to suit the experimental requirements. Apart from the readout of time spent immobile, DBscorer also provides additional data and graphics of immobility/mobility states across time revealing the evolution of behavioral despair over the duration of the test and allows the analysis of additional parameters. Such comprehensive analysis allows a more nuanced understanding of the expression of behavioral despair in FST and TST. We believe that DBscorer would make analysis of behavior in FST and TST unbiased, automated and rapid, and hence prove to be helpful to the wider neuroscience community.","2021-12","2025-05-05 17:08:39","2025-05-05 17:08:39","","NA","","6","8","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

India is the largest consumer of water, with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality & water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon.

We empirically studied the impacts of two social influence mechanisms-word-of-mouth (WOM) and observational learning (OL)-on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors.

To address the research gap, we conduct an empirical study based on the 5W1H model and data mining from five popular OSS projects on GitHub. We find that links originating from a PR are more common than the other three types of links, and links are more frequently created in Documentation.

In the 1850s, scientific writers including Auguste Comte, Herbert Spencer, and G. H. Lewes redefined biological life as dependent on an abstraction called a “medium” or “environment”- a term that united all the objects, substances, and forces in an organism's physical surroundings into a singular entity. Eliot in The Mill on the Floss draws out the ecological potential of this new biological concept by imbuing the described backgrounds of her novel with a lyrical affect I call “environmental desire,” a diffuse longing for ambient contact with one's formative medium that offers an ethical alternative to the possessive and object-driven forms of desire that drive the plot of a traditional Bildungsroman. Maggie Tulliver's marriage plot is structured by a tension between environmental desire and possessive desire, in which her erotic desire for Stephen Guest competes with a more diffuse environmental desire that attaches to the novel's described backgrounds. Ultimately, the new environment concept enables Eliot to reconceive the Bildungsroman's usual opposition between self and world as a relationship of nourishment and dependency rather than struggle, and invites a reconsideration of the ecological role of description in the Bildungsroman genre.","2021-09","2025-05-05 17:08:40","2025-05-05 17:08:40","","192-222","","2","76","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called “software ecosystems”. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.","2021","2025-05-05 17:08:40","2025-05-05 17:08:40","","194-244","","NA","49","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS","","","","Open Source Software; Episodic Volunteering; Peripheral Contributors; Software Coupling; \n Software Ecosystems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Frequently, however, a vulnerability patch is not immediately propagated to earlier releases that have been inherited by dependents, leaving residual vulnerabilities in supply chains. Our work addresses this challenge and develops a simple approach to iteratively explore the attack surface of supply chain residual vulnerabilities in open source projects. We have assessed our search scheme on 50 GitHub-hosted projects having high stars and forks: we mine their bug fix commits and identify buggy package versions to track the affected dependents and estimate the potential attack surface.

Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist. The results of this work could be used to improve corrective tasks in OSS development and some other specific linguistic aspects should be studied in detail in OSS communities.","2021-08","2025-05-05 17:08:41","2025-05-05 17:08:41","","NA","","NA","136","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER","","","","Bug fixing; Communication function; Corrective maintenance; Issue Tracking System; Open Source Software development; \n Machine learning","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One of the areas of study with scarce literature is linked with the impact of the In-formation and Communication Technologies based on collaborative environments, such as Free and Open Source Software, on the spread of the Collaborative Economy. Some questions are raised, such as: (1) To what extent do organizations linked with Collaborative Economy make use of Free and Open Source Software?, (2) What are the incentives that motivate the implementation of Free and Open Source Software in Collaborative Economy companies?, (3) What use do Collaborative Economy companies give to Free and Open Source Software?, and (4) Is there a greater use of Free and Open Source Software expected for the coming years among these organiza-tions? To answer these questions, a study based on the Delphi method has been designed. To this end, a panel of 15 high-level experts in the field was formed. From the consensus of the experts, a significant role for Free and Open Source Software in the different collaborative components and industries is evident, with the current levels practically being maintained by the year 2025.","2021-12","2025-05-05 17:08:41","2025-05-05 17:08:41","","1","","NA","173","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Organizations; Sociology; Information technology; Collaboration; Open source; Software; Incentives; Companies; open-source software; Public domain; Freeware; Property; Free; Delphi method; Fourth Industrial Revolution; Collaborative economy; Delphi; Questions","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While there have been some efforts to extract DM processes from publicly available data, the rationale behind `boo' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million mails. This paper makes two main contributions. First. it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second. it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven. bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement). Our approach can be applied to extract rationale in other OSSD communities that have similar governance structures.","2021","2025-05-05 17:08:41","2025-05-05 17:08:41","","1008-1019","","NA","NA","","","","International Conference on Software Engineering","","","","","","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software\n Engn; ACM SIGSOFT ISBN: 978-0-7381-1319-7 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","decision-making; Python; causal extraction; heuristics; Open Source Software Development (OSSD); Rationale Miner; \n rationale","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors' uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors' motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms' sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms' sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer's OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer's projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.","2021-12-22","2025-05-05 17:08:41","2025-05-05 17:08:41","","867","","3","33","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Uncertainty; Open source; Software; Open-source software; Corporate governance; Project management; Public domain; Technological change; Innovations; Target acquisition; Computers–Information Science And Information Theory","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The End Point Rate for QGIS (EPR4Q) computes a coastline projection using the End Point Rate method. The Uncertainty Bathtub Model (uBTM) analyses the effects of sea-level rise through the uncertainty of sea-level projections and the vertical error of the Digital Elevation/Terrain Model. The Bruun Rule for Google Earth Engine Model (BRGM) predicts the position of the shoreline with sea-level rise, using topographic and bathymetric data from Unmanned Aerial Vehicles and Coastal Modeling System, respectively. Based on the regional projections of the Special Report on Climate Change and Oceans and Cryosphere of the Intergovernmental Panel on Climate Change, the models were applied to a study case on the coast of Rio Grande do Sul-Brazil under different scenarios of sea-level rise expected by the end of this century. The results showed a maximum coastal retreat for the year 2100 of -502 m and -1727 m using EPR4Q and BRGM, respectively.

In this new design approach, the user defines every segment of the print-path along with all printing parameters, which may be related to geometric and non-geometric factors, at all points along the print-path. Machine control code (GCode) is directly generated by the software, without the need for any programming skills and without using computer-aided design (CAD), STL-files or slicing software. Excel is used as the front end for the software, which is written in Visual Basic. Case studies are used to demonstrate the broad range of structures that can be designed using the software, including: precisely controlled specimens for printer calibration, parametric specimens for hardware characterisation utilising hundreds of unique parameter combinations, novel mathematically defined lattice structures, and previously inconceivable 3D geometries that are impossible for traditional slicing software to achieve. The FullControl design approach enables unconstrained freedom to create nonplanar 3D print-paths and break free from traditional restrictions of layerwise print-path planning. It also allows nozzle movements to be carefully designed both during extrusion and while travelling between disconnected extrusion volumes - to overcome inherent limitations of the printing process or to improve capabilities for challenging materials. An industrial case study shows how explicit print-path design improved printer reliability, production time, and print quality for a production run of over 1000 parts. FullControl GCode Designer offers a general framework for unconstrained design and is not limited to a particular type of structure or hardware; transferability to lasers and other manufacturing processes is discussed. Parametric design files use a few bytes or kilobytes of data to describe all details that are sent to the printer, which greatly improves shareability by eliminating any risk of errors being introduced during STL file conversion or due to different users having inconsistent slicer settings. Adjustable parameters allow GCode for revised designs to be produced instantly, instead of the laborious traditional routine using multiple software packages and file conversions. The FullControl design concept offers new opportunities for creative and high-precision use of additive manufacturing systems. It facilitates design for additive manufacturing (DfAM) at the smallest possible scale based on the fundamental nature of the process (i.e. assembly of individual extrusions). The software and source code are provided as supplementary data and ongoing updates to improve functionality and the user interface will be available at www.fullcontrolgcode.com.","2021-10","2025-05-05 17:08:41","2025-05-05 17:08:41","","NA","","NA","46","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As one important module in the GREAT software, GREAT-UPD was developed for multi-GNSS and multi-frequency uncalibrated phase delay (UPD) estimation. It can provide extra-wide-lane (EWL), wide-lane (WL), and narrow-lane (NL) UPDs for GPS, GLONASS, Galileo and BDS (GREC) satellites for precise point positioning (PPP) ambiguity resolution (AR) in a multi-GNSS and multi-frequency environment. The open-source GREAT-UPD software is written in C + + 11 language following object-oriented principles and can be compiled and run on several popular operating systems, such as Windows, Linux, and Macintosh. Observations from 222 stations spanning days from DOY 091 to 120 were used to conduct multi-GNSS and multi-frequency UPD estimation and PPP AR. Results indicate that GREAT-UPD can generate stable and reliable UPD products with multi-GNSS and multi-frequency observations. After applying the UPD corrections, the multi-frequency GREC PPP AR was achieved with the averaged time to first fix of 9.0 min.

Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.","2021-09-25","2025-05-05 17:08:41","2025-05-05 17:08:41","","NA","","1","13","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC","","","","De novo drug design; Graphical user interface; Molecule generation; Web application; Deep\n learning","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Specifically, the Structure from Motion (SfM) is an emerging topographic survey technique that addresses the problem of determining the 3D position of image descriptors to estimate three-dimensional structures. Thanks to the potential of SfM algorithm and the development of Unmanned Aerial Vehicles (UAVs) that allow the ondemand acquisition of high-resolution aerial images, it is possible to survey extended areas of the Earth surface and monitor active phenomena through multi-temporal surveys. However, the ability to detect remote and wide areas with a very high-resolution is countered by the need to capture large datasets which can limit the photogrammetric process, due to the need for high-performance hardware. This paper presents a photogrammetric workflow based on Free and Open-Source Software (FOSS), which is able to return different outputs and to manage a large amount of data in reasonable time, through the distribution of the most computationally expensive steps on computing clusters hosted by the ReCaS-Bari data center for scientific research. The results are given in terms of performance evaluations based on different computing configurations of the clusters and setups of the steps of the workflow. The HTC cluster test with a parallel SSH approach involved an important reduction of several hours in the processing time of thousands UAV images, especially compared to classic photogrammetric process on a single workstation with commercial software. A parallel test, aimed to validate the performance of a single sever of the new HPC cluster, involved really good results halving the processing time with respect to the HTC cluster test.","2021-12-25","2025-05-05 17:08:42","2025-05-05 17:08:42","","NA","","NA","105","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In particular, there has been a surge in deep learning and computer vision techniques to analyse digital images. Common practice in this area is to use image pre-processing and augmentation to prevent bias and overfitting, creating a more robust deep learning model. This generally requires consultation of documentation for multiple coding libraries, as well as trial and error to ensure that the techniques used on the images are appropriate. Herein we introduce HistoClean; a user-friendly, graphical user interface that brings together multiple image processing modules into one easy to use toolkit. HistoClean is an application that aims to help bridge the knowledge gap between pathologists, biomedical scientists and computer scientists by providing transparent image augmentation and pre-processing techniques which can be applied without prior coding knowledge. In this study, we utilise HistoClean to pre-process images for a simple convolutional neural network used to detect stromal maturity, improving the accuracy of the model at a tile, region of interest, and patient level. This study demonstrates how HistoClean can be used to improve a standard deep learning workflow via classical image augmentation and pre-processing techniques, even with a relatively simple convolutional neural network architecture.

To determine the ideal time to apply an implant after augmentation with Bio-Oss Collagen and to observe if there are differences in the age of the patients and the sex, the aim of this randomized controlled clinical trial was to compare the post-extraction changes in angiogenic and osteogenic aspects during spontaneous bone regeneration with those during socket preservation using Bio-Oss Collagen. Sixty-six patients were included in this study. After 8-12 weeks, bone biopsies were embedded in paraffin and histological and immune-histological investigated. Using qRT-PCR bone (Alpl, Bglap, Runx2) and angiogenic markers (VEGF, caveolin-1) were identified. The histomorphometric analysis of all examined samples showed no differences between treated and untreated sockets, but a tissue compression. After classification in bone regeneration stages, more samples with woven bone were present in treated sockets than in controls. The Alpl expression correlates with increase in mature bone tissue. In treated sockets a significant decrease in CD34 and caveolin-1 protein expression was found. Additionally, a significant increase of Runx2 and VEGF mRNA was detected in patients younger than 50 years. Thus, all specimens showed ossification in different stages after eight weeks of healing. The treated group gives an earlier stage of ossification than controls, but produces densified tissue with greater volume fraction. It can be assumed that successful implant placement in Bio-Oss Collagen augmented extraction sockets is possible after eight weeks of bone healing. (C) 2021 Elsevier B.V.

However, in the field of civil engineering, the use of structural reliability methods unfortunately remains limited to specific cases. Most of the software available has still a limited range concerning wide parametric studies for analysis with reliability methods in civil engineering. This paper describes a new open-source software library as an effective tool for reliability analysis in civil engineering. The goal is to facilitate the adoption of reliability methods among engineers in practice as well as to provide an open platform for further scientific collaboration. The new library is being developed as a so-called “R package” in open-source programming software “R”. The package is capable of carrying out systematic parameter studies using different probabilistic reliability methods, as FORM, SORM, Monte Carlo Simulation. Based on this, an overview on the probabilistic reliability methods implemented in the package as well as results of parametric studies is given. The performance of the package will be shown with a parametric study on a practical example. Most important results of the parametric study as well as the correctness of different reliability methods will be described in the paper. By describing probabilistic methods using an example in practice, engineers can get a basic understanding behind the ideas of probability theories. Further work will result in large parameter studies, which will support the development of a new guideline for reliability in civil engineering. This guideline describes techniques of code calibration as well as to determine new partial safety factors (e.g. for non-metallic reinforced concrete, fixing anchors, etc.). Furthermore, advanced reliability methods (e.g. Monte Carlo with Subset Sampling) will be implemented in the new R package.","2021","2025-05-05 17:08:42","2025-05-05 17:08:42","","405-415","","NA","153","","","","Lecture Notes in Civil Engineering","","","","","","NA","","","","","","","Backup Publisher: Univ Minho; Inst Sustainabil & Innovat Structural Engn ISBN: 978-3-030-73618-7; 978-3-030-73616-3; 978-3-030-73615-6 Place: NA Publisher: NA","","","","NA","","Matos, J.

A compound library of 288 Schiff bases was designed based on compound 10, and a pharmacophore search was performed. Structural analysis of the top scoring hits and a docking study were used to select the best derivatives for the synthesis. Chemical synthesis and structural elucidation of compounds 16a-h were discussed. The antiproliferative activity of 16a-h was evaluated against three cancer (MCF7, A2780 and HT29, IC50 = 0.01-40.50 mu M) and one normal MRC5 (IC50 = 1.27-24.06 mu M) cell lines using the MTT assay. The results revealed the highest antiproliferative activity against MCF7 cells for 16g (IC50 = 0.01 mu M) with an exceptionally high selectivity index of (SI = 578). Cell cycle analysis of MCF7 cells treated with compound 16g revealed a cell cycle arrest at the G(2)/M phase. In addition, compound 16g induced a dose-dependent increase in apoptotic events in MCF7 cells compared to the control. In silico target prediction of compound 16g showed six potential targets that could mediate these activities. Molecular docking analysis of compound 16g revealed high binding affinities toward COX-2, MAP P38 alpha, EGFR, and CDK2. The results of the MD simulation revealed low RMSD values and high negative binding free energies for the two complexes formed between compound 16g with EGFR, and CDK2, while COX-2 was in the third order. These results highlighted a great potentiality for 16g to inhibit both CDK2 and EGFR. Taken together, the results mentioned above highlighted compound 16g as a potential anticancer agent.","2021-07","2025-05-05 17:08:43","2025-05-05 17:08:43","","NA","","13","26","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios.

More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics. The results and observations of this research include: (i) there is a significant difference between different systems concerning the LOC variable (ii) there is a significant correlation between all pairwise comparisons of internal quality metrics, and (iii) the effect of complexity and inheritance on the LOC was positive and significant, while the effect of Coupling and Cohesion was not significant.","2021-06","2025-05-05 17:08:43","2025-05-05 17:08:43","","NA","","12","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","software evolution; software engineering; software metrics; open-source software systems; internal\n quality","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For this estimation, often prediction models are used which can be learned from project data. In this paper, an approach for the usage of agent-based simulation for the prediction of software evolution trends is presented. The specialty of the proposed approach lies in the automated parameter estimation for the instantiation of project-specific simulation models. We want to assess how well a baseline model using average (commit) behavior of the agents (i.e., the developers) performs compared to models where different amount of project-specific data is fed into the simulation model. The approach involves the interplay between the mining framework and simulation framework. Parameters to be estimated include, e.g., file change probabilities of developers and the team constellation reflecting different developer roles. The structural evolution of software projects is observed using change coupling graphs based on common file changes. For the validation of simulation results, we compare empirical with simulated results. Our results showed that an average simulation model can mimic general project growth trends like the number of commits and files well and thus, can help project managers in, e.g., controlling the onboarding of developers. Besides, the simulated co-change evolution could be improved significantly using project-specific data.","2021-05","2025-05-05 17:08:43","2025-05-05 17:08:43","","NA","","1","28","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One of them is maintainability, which in turn is made up of measurable attributes. Previous studies have shown that documentation, by contributing to the comprehensibility of software, may have a positive effect on maintainability and, hence, software quality. This paper presents a study in which we analyzed Javadoc comments from 163 different open-source projects. Javadoc is the de facto standard for documenting source code files in Java projects, and although its syntax is less strict than in other (programming) languages, documentation written with Javadoc may contain violations. Our study focuses on the detection of different types of Javadoc violations as well as the source code elements affected by them. Also, by utilizing software repository mining techniques, we examined the history of the subject systems to gain further insights into the evolution of Javadoc violations. According to our results, about half of the source code elements have no Javadoc whatsoever. Among the different components of Javadoc comments (if present), the description of exceptions, by far, has the highest average ratio of violations. With regard to the types of affected elements, constructors and methods show very high average ratios. Also, we found that, on average, violations live more than two years. Nowadays, most integrated development environments (IDEs) for Java are capable of detecting missing Javadoc comments as well as comments with syntactic errors. However, our results indicate that the documentation of source code might be considered less important to developers or that these tools alone may not be sufficient for maintaining consistent documentation.","2021","2025-05-05 17:08:43","2025-05-05 17:08:43","","249-259","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc; IEEE Tech Council Software Engn ISBN: 978-1-7281-9630-5 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors.

Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels.

Software tools that automate creation of individualized reports have been built for specific studies, but are largely not open-source or broadly modifiable. We created an open-source and generalizable tool, called the Macro for the Compilation of Report-backs (MCR), to automate compilation of health study reports. We piloted MCR in two environmental exposure studies in Massachusetts, USA, and interviewed research team members (n = 7) about the impact of MCR on the report-back process. Researchers using MCR created more detailed reports than during manual report-back, including more individualized numerical, text, and graphical results. Using MCR, researchers saved time producing draft and final reports. Researchers also reported feeling more creative in the design process and more confident in report-back quality control. While MCR does not expedite the entire report-back process, we hope that this open-source tool reduces the barriers to personalizing health study reports, promotes more equitable access to individualized data, and advances self-determination among participants.","2021-06","2025-05-05 17:08:44","2025-05-05 17:08:44","","NA","","11","18","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The article presents an approach to this problem.","2021-09","2025-05-05 17:08:44","2025-05-05 17:08:44","","NA","","58","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

They are supported by peripheral developers, who contribute either via discussions or programming tasks, often for a limited time. It is unclear what role these peripheral developers play in the programming and communication efforts, as well as the temporary task-related sub-groups in the projects. We mine code-repository data and mailing-list discussions to model the relationships and contributions of developers in a social network and devise a method to analyze the temporal collaboration structures in communication and programming, learning about the strength and stability of social sub-groups in open-source software projects. Our method uses multi-modal social networks on a series of time windows. Previous work has reduced the network structure representing developer collaboration to networks with only one type of interaction, which impedes the simultaneous analysis of more than one type of interaction. We use both communication and version-control data of open-source software projects and model different types of interaction over time. To demonstrate the practicability of our measurement and analysis method, we investigate 10 substantial and popular open-source software projects and show that, if sub-groups evolve, modeling these sub-groups helps predict the future evolution of interaction levels of programmers and groups of developers. Our method allows maintainers and other stakeholders of open-source software projects to assess instabilities and organizational changes in developer interaction and can be applied to different use cases in organizational analysis, such as understanding the dynamics of a specific incident or discussion.","2021-11","2025-05-05 17:08:44","2025-05-05 17:08:44","","NA","","2","31","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Coordination; open-source software; group structures; repository mining; tensor decomposition","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, no method has been proposed to dynamically monitor the sentiment phenomena during the OSS development process. In this paper, an approach to detect Negative Sentiment-related Events (NSE) is proposed. It consists of two steps. The first step is to identify the burst interval of negative comments from open source projects, which corresponds to a NSE. The second step is to annotate this NSE with its event type. To support this approach, the types of NSEs in OSS projects are defined through an empirical study and classifiers are trained to annotate event types automatically. Moreover, conversation disentanglement techniques are employed to make the comments extracted more complete. Finally, the factors that have an influence on NSEs in the OSS project are studied.","2021","2025-05-05 17:08:44","2025-05-05 17:08:44","","92-100","","NA","NA","","","","Asia-Pacific Software Engineering Conference","","","","","","NA","","","","","","","Backup Publisher: Minist Sci & Technol; Taipei Med Univ; Acad Sinica; Foxconn Technol\n Grp; PremiumSoft ISBN: 978-1-6654-3784-4 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The advantages of crowdsourcing include a higher volume of requirements reflecting a more comprehensive array of use cases and a more engaged and committed user base. Researchers cite the inability of project teams to effectively manage an increasing volume of system requirements as a possible drawback. This paper analyzes a data set consisting of project management artifacts from 562 open-source software (OSS) projects to determine how OSS project performance varies as the share of crowdsourced requirements increases using six measures of effectiveness: requirement close-out time, requirement response time, average comment activity, the average number of requirements per crowd member, the average retention time for crowd members, and the total volume of requirements. Additionally, the models measure how the impact of increasing the share of crowdsourced requirements changes with stakeholder network structure. The analysis shows that stakeholder network structure impacts OSS performance outcomes and that the effect changes with the share of crowdsourced requirements. OSS projects with more concentrated stakeholder networks perform the best. The results indicate that requirements crowdsourcing faces diminishing marginal returns. OSS projects that crowdsource more than 70% of their requirements benefit more from implementing processes to organize and prioritize existing requirements than from incentivizing the crowd to generate additional requirements. Analysis in the paper also suggests that OSS projects could benefit from employing CrowdRE techniques and assigning dedicated community managers to more effectively channel input from the crowd.","2021-12","2025-05-05 17:08:45","2025-05-05 17:08:45","","509-534","","4","26","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

On these platforms, various information is obtained from developer activities that can then be used as developer metrics to solve a variety of challenges. In this study, we proposed new developer metrics extracted from the issue, commit, and pull request activities of developers on GitHub. We created developer metrics from the individual activities and combined certain activities according to some common traits. To evaluate these metrics, we created an item-based project recommendation system. In order to validate this system, we calculated the similarity score using two methods and assessed top-n hit scores using two different approaches. The results for all scores with these methods indicated that the most successful metrics were binary_issue_related, issue_commented, binary_pr_related, and issue_opened. To verify our results, we compared our metrics with another metric generated from a very similar study and found that most of our metrics gave better scores that metric. In conclusion, the issue feature is more crucial for GitHub compared with other features. Moreover, commenting activity in projects can be equally as valuable as code contributions. The most of binary metrics that were generated, regardless of the number of activities, also showed remarkable results. In this context, we presented improvable and noteworthy developer metrics that can be used for a wide range of open-source software development challenges, such as user characterization, project recommendation, and code review assignment.","2021-02","2025-05-05 17:08:45","2025-05-05 17:08:45","","NA","","3","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","open source; GitHub; pull request; commit; developer metric; project recommendation system; \n issue","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The proposed device has been developed with free software and hardware, which makes it a pioneering solution because it is open and accessible as well as capable of being improved by the scientific community, thereby contributing to the rapid advancement of technology. In addition, the device includes an algorithm developed ex professo that makes it possible to predetermine the regions of the celestial sphere for which, according to the geometric characteristics of the PV plant, there would be shading between the panels. In this way, solar trackers do not have to locate the Sun's position at all times according to astronomical models, while taking into account factors such as shadows or cloudiness that also affect levels of incident irradiance on solar collectors. Therefore, with this device, it is possible to provide photovoltaic plants with dual-axis solar tracking with a low-cost device that helps to optimise the trajectory of the trackers and, consequently, their radiative capture and energy production.","2021-02","2025-05-05 17:08:45","2025-05-05 17:08:45","","NA","","3","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the mathematical solution of the 3D forward intersection with the analytical definition of spatial lines, resolved by the Minimum Distances Method, is still not widespread in the academic and professional environment. This mathematical modeling determines the 3D coordinates of a point located in the middle of the minimum distance between two or more spatial lines, which spatially “intersect” towards the observation point. This solution is more accurate than others presented in the literature because it simultaneously solves the problem of 3D determination of a point by the method of least squares, in addition to providing an estimate of the coordinate precision, which are inherent to the adjustment. This work, therefore, has the objective of explaining the Minimum Distances Method for the spatial intersection of targeted measurements with a Total Station from two or more known observation points for the 3D determination of inaccessible points located in corners of buildings. For the analysis of the method, a Python tool was developed for QGIS that calculates the 3D coordinates and generates the adjustment processing report, being applied with real observations of the Geodetic survey of the SUDENE building, in Recife-PE. The methodology developed in this work proved to be suitable for measurements of large structures, achieving spherical precision better than +/- 1.0 cm, following the Brazilian standards for urban cadastre.","2021","2025-05-05 17:08:45","2025-05-05 17:08:45","","NA","","2","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Many studies point out that most bugs that adversely affect the user's experience across versions of FLOSS projects are longlived bugs. However, proposed approaches that support bug fixing procedures do not consider the real-world lifecycle of a bug, in which bugs are often fixed very fast. This may lead to useless efforts to automate the bug management process. Objective: This study aims to confirm whether the number of long-lived bugs is significantly high in popular open-source projects and to characterize the population of long-lived bugs by considering the attributes of bug reports. We also aim to conduct a comparative study evaluating the prediction accuracy of five well-known machine learning algorithms and text mining techniques in the task of predicting long-lived bugs. Methods: We collected bug reports from six popular open-source projects repositories (Eclipse, Freedesktop, Gnome, GCC, Mozilla, and WineHQ) and used the following machine learning algorithms to predict long-lived bugs: K-Nearest Neighbor, Naive Bayes, Neural Networks, Random Forest, and Support Vector Machines. Results: Our results show that long-lived bugs are relatively frequent (varying from 7.2% to 40.7%) and have unique characteristics, confirming the need to study solutions to support bug fixing management. We found that the Neural Network classifier yielded the best results in comparison to the other algorithms evaluated. Conclusion: Research efforts regarding long-lived bugs are needed and our results demonstrate that it is possible to predict long-lived bugs with a high accuracy (around 70.7%) despite the use of simple prediction algorithms and text mining methods.","2021-04","2025-05-05 17:08:45","2025-05-05 17:08:45","","NA","","NA","132","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The thermal dose is then visualized on the 2D image slices and 3D rendering using a combination of isodose lines and surfaces. Quantitative feedback is provided by dose volume histograms. The treatment plan can be iteratively edited until satisfactory dose distribution is achieved. We performed a usability study with eight novice users in which they were asked to create a satisfactory treatment plan. RESULTS: Interventionists can use the proposed system to create and visualize thermal ablation plans. Researchers can use the platform to create a wide range of specialized applications by adding plug-ins for various types of ablation methods, thermal models, and dose calculation engines. Existing extensions of the platform can provide real-time imaging and tracked or robotic navigation to aid the user in optimal needle placement. From our usability study, the users found the visual information well represented and the platform intuitive to use. The users averaged 4.4 recalculation attempts before finding an optimal treatment, which was evaluated as 100% necrosis of the tumor. CONCLUSION: The developed platform fulfills a demand for a universal and shared ablation planning system. While also being supported by the state-of-the-art development of specialized plug-ins, the open source system can adapt to the desired dose calculation or ablation procedure.","2021","2025-05-05 17:08:46","2025-05-05 17:08:46","","NA","","NA","11315","","","","Proceedings of SPIE","","","","","","NA","","","","","","","Backup Publisher: SPIE ISBN: 978-1-5106-3398-8 Place: NA Publisher: NA","","","","NA","","Fei, B.; Linte, C.

The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from ultra-high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically. Efficient analysis to find potentially toxic compounds in alternative foods and resilient foods. Identification of potentially unsafe products without the use of live animal testing. Modular free and open source design to allow for upgrading or fitting of user needs. (C) 2021 The Author(s).

As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.","2021-12-02","2025-05-05 17:08:46","2025-05-05 17:08:46","","NA","","12","23","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 130 QUEENS QUAY East, Unit 1100, TORONTO, ON M5A 0P6, CANADA Publisher: JMIR PUBLICATIONS, INC","","","","sustainability; open-source software; cancer informatics; financial model; licensing model; \n product management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The growing process of OSS has put out new ways for development, distribution and correspondence of software in organizations. Countries under international sanctions are facing extreme limitations over financial transactions and technology transmissions with different countries; therefore, individuals and companies working in such territories are involved with legal limitations and limits of copyright as to using and having access to software. This research seeks to evaluate the acceptance of OSS in a country under sanction, that's to say Iran. In this research the developed value-based acceptance model has been used. The statistical population of the study was individuals active in software and information technology industry in Iran. The sampling method was convenience sampling. The results indicated that the sanction has a significant effect on the perceived value of OSS (beta = 0.72, p = 0.000) and eventually its usage. Besides, usefulness (beta = 0.69, p = 0.001), perceived enjoyment (beta = 0.54, p = 0.000) and facilitating conditions (beta = 0.58, p = 0.002) are considered as factors effective in applying OSS.

The proposed software pipeline consists of nine main stages: 1) RGBD acquisition; 2) 2D feature extraction; 3) camera pose estimation; 4) point cloud generation; 5) coarse mesh reconstruction; 6) optional loop closure; 7) fine mesh reconstruction; 8) UV unwrapping; and 9) texture projection. This end-to-end scheme combines multiple state-of-the-art techniques and provides an easy-to-use software package for real-time 3D model reconstruction and offline texture mapping. The main innovation lies in various Structure-from-Motion (SfM) techniques that are used with additional depth data to yield high-quality 3D models in real-time and at low cost. The functionality of Open3DGen has been validated on AMD Ryzen 3900X CPU and Nvidia GTX1080 GPU. This proof-of-concept setup attains an average processing speed of 15 fps for 720p (1280x720) RGBD input without the offline backend.

The corresponding model extends a recent optimization procedure introduced to describe flame propagation in heterogeneous media featuring composition variations (equivalence ratio and temperature) in the fresh reactants or containing residual burned gases (RBG). It is based on the use of an optimized virtual species and a tabulation of the pre-exponential coefficient of an Arrhenius law. The main results of high activation energy asymptotics (AEA) are first recalled to put in evidence the key parameters and the dependence of the ignition delay on the corresponding quantities. The optimization procedure is then applied to these parameters, namely, the pre-exponential factor K and the activation energy E-a of the associated single-step Arrhenius law. An efficient tabulation method benefiting from both rapid access and low storage is proposed for the composition variable (the mixture fraction, in the present case). Finally, the restitution of both ignition and propagation features is ensured through the consideration of the cross-over temperature. The performance of the resulting model is then assessed through comparisons with data obtained from detailed chemistry computations used as reference in several conditions of increasing complexity.

These conditions, considered as a critical success factors, involve a wide range of resources, capacities and skills, both in internal and external scopes. Hence, although adopter organizations should be better prepared to face the challenges related to collaborative innovation, they do not have a systematic approach to value its readiness level to face the adoption challenges.

Design/methodology/approach - A quantitative study was designed using choose tasks that were carried out via the email discourse on the developers' email fora in five FLOSS projects. Choice process episodes were selected as the unit of analysis and were coded for the task trigger and topic. The impact of these factors on participation (i.e. the numbers of participants and messages) was assessed by regression. Findings - The results reveal differences in participation related to different task triggers and task topics. Further, the results suggest the mediating role of the number of participants in the relationships between task characteristics and the number of messages. The authors also speculate that project type serves as a boundary condition restricting the impacts of task characteristics on the number of participants and propose this relationship for future research. Research limitations/implications - Empirical support was provided to the important effects of different task characteristics on individual participation behaviors in FLOSS development tasks. Practical implications - The findings can help FLOSS participants understand participation patterns in different tasks and choose the types of tasks to attend to.

However, patient's perception of recovery and satisfaction with the surgical intervention are rarely reported. The objective of the present randomized controlled trial was to assess patient's perception of recovery after osteotome-mediated sinus floor elevation with Bio-Oss collagen compared with no grafting material. Forty healthy patients were randomly allocated to Bio-Oss collagen or no grafting material. Oral health-related quality of life was assessed by Oral Health Impact Profile-14 at enrollment. Patient's perception of recovery was assessed by self-administrated questionnaires and visual analog scale evaluating pain, social and working isolation, physical appearance, duration and quality of life alterations, eating and speaking ability, diet variations, and sleep impairment after 1 week and 1 month, respectively. Descriptive statistics was expressed as mean percentage with standard deviation. Correlation between impaired oral health-related quality of life, age, gender, and recovery were assessed by T test. Level of significance was 0.05. Results Osteotome-mediated sinus floor elevation is associated with high patient satisfaction, limited postoperative discomfort, and willingness to undergo similar surgery. Influence on patient's daily life activities seems to be minimal and limited to the first postoperative days. Most patients managed to return to work and their routine daily activities after 0-2 days. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery. However, number of days with pain, eating difficulties, and sleep disturbances were significantly increased with Bio-Oss collagen compared with no grafting material (P<0.05). Conclusion Patient's discomfort seems to be minimal and limited to the first postoperative days following osteotome-mediated sinus floor elevation with or without a grafting material. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery.","2021-03-22","2025-05-05 17:08:47","2025-05-05 17:08:47","","NA","","1","7","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: SHIROYAMA TRUST TOWER 5F, 4-3-1 TORANOMON, MINATO-KU, TOKYO, 105-6005,\n JAPAN Publisher: SPRINGER JAPAN KK","","","","Quality of life; Alveolar ridge augmentation; Dental implants; Health care surveys; Sinus floor augmentation; \n Maxilla","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

I will identify the different OSS career pathways, and develop a holistic view of women's motivations to join or leave OSS, along with their definitions of success. Based on this empirical investigation, I will work together with the Linux Foundation to design attraction and retention strategies focused on women. Before and after implementing the strategies, I will conduct empirical studies to evaluate the state of the practice and understand the implications of the strategies.","2021","2025-05-05 17:08:47","2025-05-05 17:08:47","","138-140","","NA","NA","","","","Proceedings of the IEEE-ACM International Conference on Software\n Engineering Companion","","","","","","English","","","","","","","Backup Publisher: IEEE; ACM; IEEE Comp Soc ISBN: 978-1-6654-1219-3 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","gender; open source software; success; diversity; women; inclusion; career; \n participation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The inclusion of coupled processes in simulation models is challenged by the high aspect ratio of the fractures, the complex geometry of fracture networks, and the crucial impact of processes that completely change characteristics on the fracture-rock interface. This paper provides a general discussion of design principles for introducing fractures in simulators, and defines a framework for integrated modeling, discretization, and computer implementation. The framework is implemented in the open-source simulation software PorePy, which can serve as a flexible prototyping tool for multiphysics problems in fractured rocks. Based on a representation of the fractures and their intersections as lower-dimensional objects, we discuss data structures for mixed-dimensional grids, formulation of multiphysics problems, and discretizations that utilize existing software. We further present aPythonimplementation of these concepts in the PorePy open-source software tool, which is aimed at coupled simulation of flow and transport in three-dimensional fractured reservoirs as well as deformation of fractures and the reservoir in general. We present validation by benchmarks for flow, poroelasticity, and fracture deformation in porous media. The flexibility of the framework is then illustrated by simulations of non-linearly coupled flow and transport and of injection-driven deformation of fractures. All results can be reproduced by openly available simulation scripts.","2021-02","2025-05-05 17:08:47","2025-05-05 17:08:47","","243-265","","1","25","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Power relations are present in this context whenever an entity has the power of making other entities act as it wants them to act. Therefore, these power relations could affect collaboration within an OSSECO. Objective: This research aims at investigating power relations, their benefits and challenges, and providing an understanding of them within OSSECO. The goal is to provide power relations forms description together with the power relations dynamics associated with them. Method: A systematic mapping study was conducted to extract information about power relations (forms, dynamics, benefits, and challenges) from previous studies. At the end, 10 studies reporting power relations within OSSECO were selected. Next, the data extracted from those was analyzed to understand what power relations affect the OSSECO and how this happens. Based on the results, the power relation forms and dynamics within OSSECO are defined. Results: The systematic mapping study show that power relations are present and affect relationships and interactions within an OSSECO. Moreover, 5 power relations forms and 7 power relations dynamics within OSSECO are presented. Implications: Identifying power relations that might be present within an OSSECO would enable those who study or are members of the ecosystem's community to enhance power relations that support collaboration and to avoid those who can lead developers to leave the OSSECO.","2021","2025-05-05 17:08:47","2025-05-05 17:08:47","","187-193","","NA","434","","","","Lecture Notes in Business Information Processing","","","","","","NA","","","","","","","Backup Publisher: Univ Oslo, Dept Informat ISBN: 978-3-030-91983-2; 978-3-030-91982-5 Place: NA Publisher: NA","","","","NA","","Wang, X.; Martini, A.; NguyenDuc, A.; Stray, V.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this framework, geographic information, and spatial data and tools such as UAVs (Unmanned Aerial Vehicles) and multispectral optical sensors play a crucial role in the geomatics as support techniques. PA needs software to store and process spatial data and the Free and Open Software System (FOSS) community kept pace with PA's needs: several FOSS software tools have been developed for data gathering, analysis, and restitution. The adoption of FOSS solutions, WebGIS platforms, open databases, and spatial data infrastructure to process and store spatial and nonspatial acquired data helps to share information among different actors with user-friendly solutions. Nevertheless, a comprehensive open-source platform that, besides processing UAV data, allows directly storing, visualising, sharing, and querying the final results and the related information does not exist. Indeed, today, the PA's data elaboration and management with a FOSS approach still require several different software tools. Moreover, although some commercial solutions presented platforms to support management in PA activities, none of these present a complete workflow including data from acquisition phase to processed and stored information. In this scenario, the paper aims to provide UAV and PA users with a FOSS-replicable methodology that can fit farming activities' operational and management needs. Therefore, this work focuses on developing a totally FOSS workflow to visualise, process, analyse, and manage PA data. In detail, a multidisciplinary approach is adopted for creating an operative web-sharing tool able to manage Very High Resolution (VHR) agricultural multispectral-derived information gathered by UAV systems. A vineyard in Northern Italy is used as an example to show the workflow of data generation and the data structure of the web tool. A UAV survey was carried out using a six-band multispectral camera and the data were elaborated through the Structure from Motion (SfM) technique, resulting in 3 cm resolution orthophoto. A supervised classifier identified the phenological stage of under-row weeds and the rows with a 95% overall accuracy. Then, a set of GIS-developed algorithms allowed Individual Tree Detection (ITD) and spectral indices for monitoring the plant-based phytosanitary conditions. A spatial data structure was implemented to gather the data at canopy scale. The last step of the workflow concerned publishing data in an interactive 3D webGIS, allowing users to update the spatial database. The webGIS can be operated from web browsers and desktop GIS. The final result is a shared open platform obtained with nonproprietary software that can store data of different sources and scales.","2021-04","2025-05-05 17:08:48","2025-05-05 17:08:48","","NA","","4","10","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For instance, open source software (OSS) is developed by mass collaboration on digital communities to provide software users free alternatives to commercial products. OSS is particularly valuable to meet the needs of numerous disadvantaged users for whom proprietary software is not affordable. While OSS projects are lack of formal organizational structure, project leaders play a significant role in initiating and managing these projects and eventually, influencing the degree to which the developed software is used and liked by users. Drawing on resource dependence theory, we investigate the impacts of two team-level characteristics of OSS project leaders (ie, size and tenure) on how well the developed software can address users' needs, with regard to the quantity of software being used by users and the quality of software to users' satisfaction. Further, from a resource dependence perspective, we examine the moderating role of project leaders' network ties in shaping the contingency of these effects. By using a large-scale dataset from 43 048 OSS development projects in SourceForge community, we find empirical evidence corroborating our theory. Taken together, our findings suggest the boundary-spanning role of project leaders in developing digital social innovation.","2021-09","2025-05-05 17:08:48","2025-05-05 17:08:48","","672-694","","5, SI","31","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Open source; software development; open source software; Open-source software; resource dependence theory; social innovation; Software development; Public domain; Freeware; Project; Innovations; Organizational structure; User satisfaction; Contingency; digital innovation; project leaders; Resource dependence theory; Social innovation; Computers–Computer Systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Thus, the pursuit of complementary approaches to quantify growth kinetics becomes mandatory in order to better understand fungal cell growth. Furthermore, it is well-known that filamentous fungi, including Aspergillus spp., have distinct modes of growth and differentiation under sub-aerial conditions on solid media or submerged cultures. Here, we detail a quantitative microscopic method for analyzing growth kinetics of the model fungus Aspergillus nidulans, using live imaging in both submerged cultures and solid media.

However, obtaining Koc requires a significant amount of time and enormous expenditure. Thus, it is necessary to efficiently estimate Koc in the early stages of a chemical?s development. In this study, a quantitative structure-property relationship (QSPR) model was developed using calculated physicochemical properties and molecular descriptors with the OPEn structure-activity/property Relationship App (OPERA) and Mordred software using the largest available Koc dataset. Specifically, we compared the accuracies of the model using the light gradient boosted machine (LightGBM), a gradient boosting decision tree (GBDT) algorithm, with those of previous models. The experimental results suggested the potential to develop a QSPR model that will produce highly accurate Koc values using molecular descriptors and physicochemical properties. Unlike previous studies, the use of a combination of LightGBM, OPERA and Mordred enables the prediction of Koc for many chemicals with high accuracy. In this study, OPERA was used to calculate the physicochemical properties, and Mordred was used to calculate molecular descriptors. The wide range of chemicals covered by OPERA and Mordred enables the analysis of a diverse range of chemical compounds. We also report a method to tune the LightBGM program. The use of fast-processing software, such as LightGBM, enables parameter tuning of a method required to obtain best performance. Our research represents one of the few studies in the field of environmental chemistry to use LightGBM. Using physicochemical properties as well as molecular descriptors, we could develop highly accurate Koc prediction models when compared to prior studies. In addition, our QSPR models may be useful for preliminary environmental risk assessment without incurring significant costs during the early chemical developmental stage.","2021-05","2025-05-05 17:08:48","2025-05-05 17:08:48","","NA","","NA","196","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While a number of studies proposed novel methods of representing expertise within individual projects, these methods are difficult to apply at an ecosystem level. However, with the focus of software development shifting from monolithic to modular, a method of representing developers' expertise in the context of the entire OSS development becomes necessary when, for example, a project tries to find new maintainers and look for developers with relevant skills. Aim: We aim to address this knowledge gap by proposing and constructing the Skill Space where each API, developer, and project is represented and postulate how the topology of this space should reflect what developers know (and projects need). Method: we use the World of Code infrastructure to extract the complete set of APIs in the files changed by open source developers and, based on that data, employ Doc2Vec embeddings for vector representations of APIs, developers, and projects. We then evaluate if these embeddings reflect the postulated topology of the Skill Space by predicting what new APIs/projects developers use/join, and whether or not their pull requests get accepted. We also check how the developers' representations in the Skill Space align with their self-reported API expertise. Result: Our results suggest that the proposed embeddings in the Skill Space appear to satisfy the postulated topology and we hope that such representations may aid in the construction of signals that increase trust (and efficiency) of open source ecosystems at large and may aid investigations of other phenomena related to developer proficiency and learning.","2021","2025-05-05 17:08:49","2025-05-05 17:08:49","","995-1007","","NA","NA","","","","International Conference on Software Engineering","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc; IEEE Tech Council Software\n Engn; ACM SIGSOFT ISBN: 978-0-7381-1319-7 Place: NA Publisher: IEEE Press","","","","Open Source; Machine Learning; API; World of Code; API embedding; Developer embedding; Developer Expertise; Doc2Vec; Expertise; Project embedding; Skill Space; Vector Embedding","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Root characteristics like length, diameter and volume are critical to measure to understand plant and soil functions. RhizoVision Explorer is an open-source software designed to enable researchers interested in roots by providing an easy-to-use interface, fast image processing and reliable measurements. The default broken roots mode is intended for roots sampled from pots and soil cores, washed and typically scanned on a flatbed scanner, and provides measurements like length, diameter and volume. The optional whole root mode for complete root systems or root crowns provides additional measurements such as angles, root depth and convex hull. Both modes support providing measurements grouped by defined diameter ranges, the inclusion of multiple regions of interest and batch analysis. RhizoVision Explorer was successfully validated against ground truth data using a new copper wire image set. In comparison, the current reference software, the commercial WinRhizo (TM), drastically underestimated volume when wires of different diameters were in the same image. Additionally, measurements were compared with WinRhizo (TM) and IJ_Rhizo using a simulated root image set, showing general agreement in software measurements, except for root volume. Finally, scanned root image sets acquired in different labs for the crop, herbaceous and tree species were used to compare results from RhizoVision Explorer with WinRhizo (TM). The two software showed general agreement, except that WinRhizo (TM) substantially underestimated root volume relative to RhizoVision Explorer. In the current context of rapidly growing interest in root science, RhizoVision Explorer intends to become a reference software, improve the overall accuracy and replicability of root trait measurements and provide a foundation for collaborative improvement and reliable access to all.","2021-09-13","2025-05-05 17:08:49","2025-05-05 17:08:49","","NA","","6","13","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GREAT CLARENDON ST, OXFORD OX2 6DP, ENGLAND Publisher: OXFORD UNIV PRESS","","","","Ground truth; phenomics; phenotyping; rhizosphere; traits; root system\n architecture","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

C57BL/6 mice were intraperitoneally injected with STZ for 5 days to simulate the diabetic cardiomyopathy model. Mice with STZ-induced diabetes (STZ-DM1) were orally administered OSS-128167 (20 or 50 mg/kg) through gavage every other day. The expression of SIRT6 in myocardial tissue was detected using western blotting. Tissue staining (hematoxylin and eosin and Masson's trichrome) was used to characterize myocardial structure, TUNEL fluorescent staining was used to detect myocardial apoptosis, and immunohistochemical staining was used to detect the expression of inflammatory factors in myocardial tissue. Dihydroethidium staining and a malondialdehyde (MDA) detection kit were used to detect the oxidative stress levels in myocardial tissues. In vitro, H9c2 cells were pre-incubated with OSS-128167 for 1 h and then stimulated with HG (33 mM) for various durations. Expression levels of fibrosis markers, collagen-1 and transforming growth factor (TGF)-beta, apoptosis-related proteins, Bax, Bcl-2 and cleaved-poly ADP-ribose polymerase, tumor necrosis factor-alpha and the oxidative stress metabolite, 3-nitrotyrosine were analyzed using western blotting and reverse transcription-quantitative PCR. Commercially available kits were used to detect the activity of caspase-3 and the content of MDA in the H9c2 cell line. The corresponding results demonstrated that OSS-128167 aggravated diabetes-induced cardiomyocyte apoptosis and fibrosis in mice. Mechanistically, OSS-128167 was revealed to increase the levels of inflammatory factors and reactive oxygen species (ROS) in vitro and in vivo. In conclusion, OSS-128167 facilitated the inflammatory response and promoted the production of ROS while aggravating DCM development. These findings indicated that SIRT6 may target two closely combined and interacting pathological processes, the inflammatory response and oxidative stress, and may serve as a potentially advantageous therapeutic target.","2021-05","2025-05-05 17:08:49","2025-05-05 17:08:49","","NA","","5","23","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results indicate that real networks are mainly characterized by the modular small-world structure, which is inherently correlated with the sub-project participation of developers. Most module members are single-dimensional developers whose coding-collaboration focuses on a small number of sub-projects (called the main dimension of the module), while a small proportion of module members are multi-dimensional developers who conduct coding-collaboration in the main dimension of different modules.

In this study, we map out the community structure of a large open source project and observe its bug-fixing patterns to explore the relationship between tasks and structure.

ImageJ is an open-source image analysis software platform that has aided researchers with a variety of image analysis applications, driven mainly by engaged and collaborative user and developer communities. The close collaboration between programmers and users has resulted in adaptations to accommodate new challenges in image analysis that address the needs of ImageJ's diverse user base. ImageJ consists of many components, some relevant primarily for developers and a vast collection of user-centric plugins. It is available in many forms, including the widely used Fiji distribution. We refer to this entire ImageJ codebase and community as the ImageJ ecosystem. Here we review the core features of this ecosystem and highlight how ImageJ has responded to imaging technology advancements with new plugins and tools in recent years. These plugins and tools have been developed to address user needs in several areas such as visualization, segmentation, and tracking of biological entities in large, complex datasets. Moreover, new capabilities for deep learning are being added to ImageJ, reflecting a shift in the bioimage analysis community towards exploiting artificial intelligence. These new tools have been facilitated by profound architectural changes to the ImageJ core brought about by the ImageJ2 project. Therefore, we also discuss the contributions of ImageJ2 to enhancing multidimensional image processing and interoperability in the ImageJ ecosystem.","2021-01","2025-05-05 17:08:50","2025-05-05 17:08:50","","234-249","","1, SI","30","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS project success is reflected in two forms: popularity and knowledge creation. Extending the extant OSS literature, we theorize a contingent role of interproject connectedness. In particular, we posit three points: (1) an OSS project with more structural holes achieves higher popularity; (2) an OSS project with fewer structural holes yields higher knowledge creation; and (3) these two relationships are enhanced by an increase in project maturity. Using a dataset longitudinally collected from SourceForge.net, we found that OSS projects with widespread connectedness are more popular.

This is especially important for ""infrastructure"" projects, such as critical libraries and programming languages that many other people depend on. Some projects have taken the approach of borrowing planning tools that originated in commercial development, despite the fact that these techniques were designed for very different contexts, e.g. strong top-down control and profit motives. Little research has been done to understand how these practices are adapted to a new context. In this paper, we examine the Rust project's use of roadmaps: how has an important OSS infrastructure project adapted an inherently top-down tool to the freewheeling world of OSS? We find that because Rust's roadmaps are built in part by summarizing what motivated developers most prefer to work on, they are in some ways more a description of the motivated labor available than they are a directive that the community move in a particular direction. They allow the community to avoid wasting time on unpopular proposals by revealing that there will be little help in building them, and encouraging work on popular features by making visible the amount of consensus in those features.

In addition, factors able to compromise the environmental status of the Mar Piccolo ecosystem were also evaluated. The methodological workflow developed lets extract significant individual frames from the captured video tracks, improves images by applying five image processing algorithms, georeferences the individual frames based on flight data, and implements the processed data in a thematic Geographical Information System. All mussel farms, in operation and derelict, all partially submerged and/or water-coated invisible to navigation poles and other elements such as illegal fishing nets and marine litter on the seabed up to about 2 m deep, have been identified and mapped.

However, these models lack consensus between scholars as well as standard bodies on a specific set of usability evaluation criteria. Retaining irrelevant criteria and omitting essential ones will mislead the direction of the usability evaluation. Objective: This study introduces a three-step method to develop a usability evaluation model in the context of OSS. Method: The fuzzy Delphi method has been employed to unify the usability evaluation criteria in the context of OSS. The first step in the method is the usability criteria analysis, which involves redefining and restructuring all collected usability criteria reported in the literature. The second step is fuzzy Delphi analysis, which includes the design and validates the fuzzy Delphi instrument and the utilisation of the fuzzy Delphi method to analyse the fuzziness consensus of experts' opinions on the usability evaluation criteria. The third step is the proposal of the OSS usability evaluation model. Results: A total of 124 usability criteria were identified, redefined, and restructured by creating groups of related meaning criteria. The result of the groupings generated 11 main criteria; the findings of the fuzzy Delphi narrowed down the criteria to only seven. The final set of criteria was sent back to the panellists for reconsideration of their responses. The panellists verified that these criteria are suitable in the evaluation of the usability of OSS. Discussion: The empirical analysis confirmed that the proposed evaluation model is acceptable in assessing the usability of OSS. Therefore, this model can be used as a reference metric for OSS usability evaluation which will have a practical benefit for the community in public and private organisations in helping the decision-maker to select the best OSS software package amongst the alternatives.","2021-02","2025-05-05 17:08:51","2025-05-05 17:08:51","","NA","","NA","130","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, some benchmark problems have been solved with DualSPHysics to validate the estimation of wave impact pressure with violent breaking waves. We have demonstrated three main results: (i) as an alternative to the artificial viscosity traditionally used in DualSPHysics, a laminar viscosity model can also well reproduce the solutions to the existing benchmark problems in a violent flow field with the modified dynamic boundary condition; (ii) the dynamics of the gas phase is essential in the calculation of wave breaking with rapid gate opening; and (iii) if the density diffusion parameter is too large, the impact pressure may be underestimated. The practical contribution by this study is to find that DualSPHysics well reproduces complex breaking waves, including multi-phase gas-liquid flows, and that the wave impact pressure is accurate by comparison with existing experimental results. This allows us to understand the complex behavior of fluid-structure interactions in coastal engineering by means of DualSPHysics.","2021-10-02","2025-05-05 17:08:52","2025-05-05 17:08:52","","545-572","","4","63","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Such systems save a great deal of effort over ad hoc ways of advertising, packaging, and transmitting useful libraries, but coordination among project teams is still needed when one package makes a breaking change affecting other packages. Ecosystems differ in their approaches to breaking changes, and there is no general theory to explain the relationships between features, behavioral norms, ecosystem outcomes, and motivating values. We address this through two empirical studies. In an interview case study, we contrast Eclipse, NPM, and CRAN, demonstrating that these different norms for coordination of breaking changes shift the costs of using and maintaining the software among stakeholders, appropriate to each ecosystem's mission. In a second study, we combine a survey, repository mining, and document analysis to broaden and systematize these observations across 18 ecosystems. We find that all ecosystems share values such as stability and compatibility, but differ in other values. Ecosystems' practices often support their espoused values, but in surprisingly diverse ways.

Hence, there is a constant race for defenders to find and patch them before attackers are able to exploit them. Measuring different aspects of this process is important in order to better understand it and improve the odds for defenders. (Aims) The human factor of the vulnerability discovery and patching process has received limited attention. Better knowledge of the characteristics of the people and organizations who discover and report security vulnerabilities can considerably enhance our understanding of the process, provide insights regarding the expended effort in vulnerability hunting, contribute to better security metrics, and help guide practical decisions regarding the strategy of projects to attract vulnerability researchers.(Method) In this paper, we present what is, to the best of our knowledge, the first large-scale empirical study on the people and organizations who report vulnerabilities in popular FLOSS projects. Collecting data from a multitude of publicly available sources (NVD, bug-tracking platforms, vendor advisories, source code repositories), we create a dataset of reporter information for 2193 unique reporting entities of 4756 CVEs affecting the Mozilla suite, Apache httpd, the PHP interpreter, and the Linux kernel. We use the dataset to investigate several aspects of the vulnerability discovery process, specifically regarding the distribution of contributions, their temporal characteristics, and the motivations of reporters.(Results) Among our results: around 80% of reports come from 20% of reporters; first time reporters are significant contributors to the yearly total in all 4 projects; productive reporters are specialized w.r.t. the project and vulnerability types; around half of all reports come from reporters acknowledging an affiliation.(Conclusions) Projects depend both on a core of dedicated and productive reporters, and on small contributions from a large number of community reporters.

While many laboratories have software that is used internally, reproducibility requires the availability of open-source software. Therefore, we here introduce the `SleepCycles' package for R, an open-source software package that identifies sleep cycles and their respective (non-) rapid eye movement ([N]REM) periods from sleep staging data. Additionally, each (N)REM period is subdivided into parts of equal duration (percentiles), which may be useful for further fine-grained analyses. The detection criteria used in the package are, with some adaptations, largely based on criteria originally proposed by Feinberg and Floyd (1979). The latest version of the package can be downloaded from the Comprehensive R Archives Network (CRAN). The package `SleepCycles' for R allows to identify sleep cycles and their respective NREM and REM periods from sleep staging results. Besides the cycle detection, NREM and REM periods are also split into parts of equal duration (percentiles) thereby allowing for a better temporal resolution across the night and comparisons of sleep cycles with different durations amongst different night recordings.

Among these new technologies is fiber photometry, a technique wherein an implanted fiber optic is used to record signals from genetically encoded fluorescent sensors in bulk tissue. Fiber photometry has been widely adapted due to its cost-effectiveness, ability to examine the activity of neurons with specific anatomical or genetic identities, and the ability to use these highly modular systems to record from one or more sensors or brain sites in both superficial and deep-brain structures. Despite these many benefits, one major hurdle for laboratories adopting this technique is the steep learning curve associated with the analysis of fiber photometry data. This has been further complicated by a lack of standardization in analysis pipelines. In the present communication, we present pMAT, a `photometry modular analysis tool' that allows users to accomplish common analysis routines through the use of a graphical user interface.

At present, however, it still lacks a powerful, easy-to-use, and user-friendly professional software concerning generation and assessment of digital speckle pattern. Researchers have to reimplement the generation algorithms in literature by themselves, which is time-consuming and error-prone. This paper reports a free and open-source software, Glare, for generation and assessment of digital speckle pattern. Glare has functions including generating speckle patterns, rendering deformed images, assessing pattern quality, and presenting pattern recommendations: Glare can generate ellipse, polygon, and Gaussian speckle patterns; can render deformed images with underlying deformation fields of translation, stretch/compression, rotation, sinusoidal deformation, Gaussian deformation, and Portevin-Le Chatelier band deformation; can calculate key pattern quality assessment parameters such as speckle coverage, speckle size, systematic error, and random error; can produce optimized speckle pattern in form of vector image. The software realizes real-time deformed image rendering with the aid of fast initial value estimation algorithm for backward mapping and pattern pre-rendering technique, and improves the computational efficiency of sum of square of subset intensity gradients by integral image method.

Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg's motivation-hygiene framework, we explore how developers' perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.","2022-01","2025-05-05 17:08:53","2025-05-05 17:08:53","","165-195","","1","23","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: GEORGIA STATE UNIV, 35 BROAD STREET, STE 916-917, ATLANTA, GA 30303 USA Publisher: ASSOC INFORMATION SYSTEMS","","","","Motivation; Open Source Software; Code Contribution; Multilevel Growth Analysis; Payment; Value Fit; \n Change Over Time","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper presents a new workflow of automated image processing to utilize poor-quality X-ray CT scan images. The workflow runs on the open-source image analysis software and efficiently separates desired features from low-contrast scanned images. The new workflow is a two-step technique using contrast enhancement and automated feature segmentation to generate noise-free binary images. The results of binary images using the proposed workflow and using a conventional thresholding technique are analyzed to show the quality of the proposed method. The paper also presents a workflow of estimating the structural geometries of features in two and three dimensions. The results of the structural feature analyses and computational time were compared between the open-source (ImageJ) and commercial image analysis software (Bruker Computed Tomography Analyzer).

In this work, each bug report is endowed with a response variable (bug-fixing time), external to its words, that we are interested in predicting. To analyze the bug reports collections, we used a supervised Latent Dirichlet Allocation (sLDA), whose goal is to infer latent topics that are predictive of the response. The bug reports and the responses are jointly modeled, to find latent topics that will best predict the response variables for future unlabeled bug reports. With a fitted model in hand, we can infer the topic structure of an unlabeled bug report and then form a prediction of its response. sLDA adds to LDA a response variable connected to each bug report. Two different variants of the bag-of-words (BoW) model are used as baseline discriminative algorithms and also an unsupervised LDA is considered. To evaluate the proposed approach the defect tracking dataset of LiveCode, a well-known and large dataset, was used.

Here we present a wide range of free and open source software tools that are used in biomedical sequencing workflows around the world today. Since its introduction in 2011 the variant call format (VCF) has been widely adopted for processing DNA and RNA variants in practically all population studies-as well as in somatic and germline mutation studies. The VCF format can represent single nucleotide variants, multi-nucleotide variants, insertions and deletions, and simple structural variants called and anchored against a reference genome.Here we present a spectrum of over 125 useful, complimentary free and open source software tools and libraries, we wrote and made available through the multiple vcflib, bio-vcf, cyvcf2, hts-nim and slivar projects. These tools are applied for comparison, filtering, normalisation, smoothing and annotation of VCF, as well as output of statistics, visualisation, and transformations of files variants. These tools run everyday in critical biomedical pipelines and countless shell scripts.

The rule established from the case of Foss vs. Harbottle, which paved way for exploitation of the minority shareholders, giving excessive power at the hands of the office-bearers, has always been a hindrance to secure a protection to the minority shareholders who do not get an opportunity to approach the Court for seeking justice as they are considered unauthorised to do so. The instances whereby the rights of the minority shareholders have been infringed or violated are enormous in number, and the requirement to secure an amicable environment for these small in shareholdings yet large numbers of shareholders has increased with time. Recently, in the judgment, considering the prevalence of the majority rule, the decision was given in favour of the majority shareholders of the Company, posing a threat to the position of the minority shareholders, yet again in the corporate world. Thus, the researcher here, attempts to critically analyse the majority rule, discussing in brief the case of Foss vs. Harbottle developed contrary to the interests of the minority shareholders, and appraise the exceptions provided under the Majority rule which also acts as a measure to protect the rights of minority shareholders. The researcher has tried to analyse the case of Cyrus Mistry trying to identifying as to how the Courts have failed to provide protection to the minority shareholders and this acts like a set back to the same.","2022","2025-05-05 17:08:54","2025-05-05 17:08:54","","4488-4493","","2","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Research was performed on ovariectomized rats as a model of osteoporosis (with sham-operated control group). The animals were treated with alendronate, hop extract or the combination of the two. Whole histological slides were photographed and images were manually pre-processed in Gimp. Color masks from Gimp were loaded in FIJI and polar transformation and meas-urements were made using a custom macro. This analysis was supplemented by manual assessment of Ki67 proliferation marker expression by a pathologist. Our results suggest that monotherapy or combination therapy with alendronate and hop extract does not cause proliferation of the endometrium in ovariectomized rats and would be safe for use in osteoporosis treatment in this regard.

To mitigate these problems, we developed AlphaSQL: an open-source software tool for SQL data processing. AlphaSQL mainly supports three techniques to automate data preparation by SQL: (1) extracting a directed acyclic graph (DAG) based on dependencies between SQL and data, (2) validating the schema included in the whole DAG, and (3) parallelizing the queries based on the DAG. We applied AlphaSQL to a real-world data analysis and machine learning project where we analyzed 1445 logs obtained from static validation for git commits and 3243 execution logs.

While 3DP has gained tremendous popularity, it remains a daunting and perceptibly time-consuming process for the inexperienced user, with most turning to commercially printed products. Commercial vendors are expensive. We propose that 3DP is feasible for the inexperienced user with the appropriate knowledge and tools.Methods: A 3DP protocol was created for model design and printing using open-source software and a low-cost desktop printer. It was betatested by 3 inexperienced users. The fidelity of the protocol was then tested in direct comparison to industry models made for 3 patients undergoing mandibular distraction osteogenesis, using standard cephalometric measurements.Results: All inexperienced testers were able to successfully create a 3D model using the easy-to-follow protocol without the use of any other resources. The models were created in a mean time of 170 minutes. All cephalometric measurements on the open-source printed models were equal to within 0.5 to 1.0 mm of the respective industry models.Conclusions: As the 3DP process is simplified and desktop printers and materials become more affordable, we anticipate that its implementation will become more commonplace.

At the same time, it is important to understand which issues practitioners face when they are using a specific open source license, when they are developing new open source software products or when they are reusing open source software. In this work, we examine questions posed about open source software licensing using data from the following Stack Exchange sites: Stack Overflow, Software Engineering, Open Source and Law. We analyze the indication of specific licenses and topics in the questions, investigate the attention the posts receive and trends over time, whether appropriate answers are provided and which type of questions are asked. Our results indicate that practitioners need, among other, clarifications about licensing specific software when other licenses are used, and for understanding license content. The results of the study can be useful for educators and employers, organizations that are authoring open source software licenses and developers for understanding the issues faced when using licenses, whereas they are relevant to other software engineering research areas, such as software reusability.

GNSS is a high-accuracy technique that is widely used today for monitoring and detecting deformations in the earth's crust and engineering structures. However, difficulties are encountered in the evaluation of measurements due to the intensive use of statistics in deformation analysis and the high numerical calculation load. Considering the possible consequences of deformations in the earth's crust and engineering structures, strategies and evaluation software are needed to determine them quickly. In this study, an open-source software that can be used in the analysis of deformation surveys carried out in campaigns with the static GNSS technique were developed by using R programming language since open-source deformation analysis software is missing in the field of deformation analysis. The method chosen for the determination of deformations is presented. The general features of the developed software are introduced, and a case study was carried out to test the computational performance of the software and to investigate which parameters are effective in determining the amount of deformation in GNSS networks correctly. As a result of the study, it was seen that ambiguity resolution rates and ionospheric activity affect the accuracy of the deformations determined in GNSS networks.","2022-09","2025-05-05 17:08:56","2025-05-05 17:08:56","","2051-2062","","3","15","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the technical skills required to extract tailored information about land cover dynamics from these open-access geospatial data often limit their use by those making landscape management decisions. Using Dartmoor National Park as an example, we demonstrate an open-source toolkit which uses open-source software (QGIS and RStudio) to process freely available Sentinel-2 and public LiDAR data sets to produce fine scale (10 m(2) grain size) land cover maps. The toolbox has been designed for use by staff within the national park, for example, enabling land cover maps to be updated as required in the future. An area of 945 km(2) was mapped using a trained random forest classifier following a classification scheme tailored to the needs of the national park. A 2019 land cover map had an overall user's accuracy of 79%, with 13 out of 17 land cover classes achieving greater than 70% accuracy. Spatially, accuracy was related via logistical regression to blue band surface reflectance in the spring and topographic slope derived from LiDAR (1 m resolution), with greater accuracy in steeper terrain and areas exhibiting higher blue reflectance. Between an earlier (2017-2019) and later (2019-2021) time frame, 8% of pixels changed, most of the change by area occurred in the most common classes. However, the largest proportional increase occurred in Upland Meadows, Lowland Meadows and Blanket Bog, all habitats subject to restoration efforts. Identifying areas of change enables future field work to be better targeted. We discuss the application of this mapping to land management within the Dartmoor national park and of the potential of tailored land cover and land cover change mapping, via this toolbox, to evidence-based environmental decision-making more widely.","2022-06","2025-05-05 17:08:56","2025-05-05 17:08:56","","NA","","3","3","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In a similar way, community smells consider the sub-optimal patterns in the organizational and social structures of software teams. Related work performed empirical studies to identify the relationship between community smells and software smells at the architecture and code levels. However, how community smells relate with design smells is still unknown. Aims: In this paper, we empirically investigate the relationship between community smells and design smells during the evolution of software projects. Method: We apply three statistical methods: correlation, trend, and information gain analysis to empirically examine the relationship between community and design smells in 100 releases of 10 large-scale Apache open-source software projects. Results: Our results reveal that the relationship between community and design smells varies across the analyzed projects. We find significant correlations and trend similarities for one type of community smell (when developers work in isolation without peer communication-Missing Links) with design smells in most of the analyzed projects. Furthermore, the results of our statistical model disclose that community smells are more relevant for design smells compared to other community-related factors. Conclusion: Our results find that the relationship of community smells (in particular, the Missing Links smell) exists with design smells. Based on our findings, we discuss specific community smell refactoring techniques that should be done together when refactoring design smells so that the problems associated with the social and technical (design) aspects of the projects can be managed concurrently.","2022","2025-05-05 17:08:56","2025-05-05 17:08:56","","23-33","","NA","NA","","","","International Symposium on Empirical Software Engineering and\n Measurement","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; Aalto Univ; Univ Helsinki ISBN: 978-1-4503-9427-7 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Community Smells; Design Smells; Open-Source Development.; Social Smells; Socio-Technical Analysis","","Lassenius, C.; Madeiral, F.; Conte, T.; Mannisto, T.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a “rising contributor” badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.","2022","2025-05-05 17:08:56","2025-05-05 17:08:56","","36-40","","NA","NA","","","","ICSE-SEIS '22","","","","","","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery ISBN: 978-1-6654-9594-3 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","open source; maintainers; social good","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The lack of efficient tools to accurately model tissue structures and subsequently perform quantitative multiphysics modeling greatly impedes the clinical translation of these modalities. Aim: Although the mesh-based Monte Carlo (MMC) method expands our capabilities in simulating complex tissues using tetrahedral meshes, the generation of such domains often requires specialized meshing tools, such as Iso2Mesh. Creating a simplified and intuitive interface for tissue anatomical modeling and optical simulations is essential toward making these advanced modeling techniques broadly accessible to the user community. Approach: We responded to the above challenge by combining the powerful, open-source three-dimensional (3D) modeling software, Blender, with state-of-the-art 3D mesh generation and MC simulation tools, utilizing the interactive graphical user interface in Blender as the front-end to allow users to create complex tissue mesh models and subsequently launch MMC light simulations. Results: Here, we present a tutorial to our Python-based Blender add-on-BlenderPhotonics- to interface with Iso2Mesh and MMC, which allows users to create, configure and refine complex simulation domains and run hardware-accelerated 3D light simulations with only a few clicks. We provide a comprehensive introduction to this tool and walk readers through five examples, ranging from simple shapes to sophisticated realistic tissue models. Conclusions: BlenderPhotonics is user friendly and open source, and it leverages the vastly rich ecosystem of Blender. It wraps advanced modeling capabilities within an easy-to-use and interactive interface. The latest software can be downloaded at http://mcx.space/bp. (C) The Authors.

In these studies, segmentation and quantification of myocardial infarct lesion are often performed with a commercial software or an in-house closed-source code development thus creating a barrier for reproducible research. This paper introduces CMRSegTools: an open-source application software designed for the segmentation and quantification of myocardial infarct lesion enabling full access to state-of-the-art segmentation methods and parameters, easy integration of new algorithms and standardised results sharing. This post-processing tool has been implemented as a plug-in for the OsiriX/Horos DICOM viewer leveraging its database management functionalities and user interaction features to provide a bespoke tool for the analysis of cardiac MR images on large clinical cohorts. CMRSegTools includes, among others, user-assisted segmentation of the left-ventricle, semi- and automatic lesion segmentation methods, advanced statistical analysis and visualisation based on the American Heart Association 17-segment model. New segmentation methods can be integrated into the plug-in by developing components based on image processing and visualisation libraries such as ITK and VTK in C++ programming language. CMRSegTools allows the creation of training and testing data sets (labeled features such as lesion, microvascular obstruction and remote ROI) for supervised Machine Learning methods, and enables the comparative assessment of lesion segmentation methods via a single and integrated platform. The plug-in has been successfully used by several CMR imaging studies.","2022-09-13","2025-05-05 17:08:56","2025-05-05 17:08:56","","NA","","9","17","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Not addressing it in time leads to development crises, where focus and resources must be shifted to address existing issues. Existing software tools allow measuring the level of debt and pinpointing its sources, which can help practitioners control it. In the present paper we aim to investigate the prevalence, characteristics, and evolution of technical debt in several open-source applications. We used SonarQube to study 112 application versions that covered more than 15 years of development for each application. We studied the way debt characteristics and source code distribution evolved over the target applications' lifecycles. We addressed concerns regarding the accuracy of the analysis and illustrated some of the limitations of existing tools. We observed that a small number of issue types were responsible for most of the debt. We found that each application had its own technical debt particularities.

To better understand user behaviors in OSS user forums, we carried out an empirical study analyzing about 1.3 million posts from user forums of four popular OSS applications: Zotero, Audacity, VLC, and RStudio. Through analyzing the contribution patterns of three common user types (end-users, developers, and organizers), we observed that end-users not only initiated most of the threads (above 96% of threads in three projects, 86% in the other), but also acted as the significant contributors for responding to other users' posts, even though they tended to lack confidence in their activities as indicated by psycho-linguistic analyses. Moreover, we found end-users more open, reflecting a more positive emotion in communication than organizers and developers in the forums.

However, high-quality code comments or method names are often unavailable due to tight project schedules or other reasons in open-source software ecosystems such as Github. Therefore, in this work, we try to use deep learning models to generate appropriate code comments or method names to help software development and maintenance, which requires a non-trivial understanding of the code. Therefore, we propose a Graph neural network enhanced Transformer model (GTrans for short) to learn code representation to understand code better. Specifically, GTrans learns code representation from code sequences and graphs. We use a Transformer encoder to capture the global representation from code sequence and a graph neural network (GNN) encoder to focus on the local details in the code graph, and then use a decoder to combine both global and local representations by attention mechanism. We use three public datasets collected from GitHub to evaluate our model. In an extensive evaluation, we show that GTrans outperforms the state-of-the-art models up to 3.8% increase in METEOR metrics on code comment generation and outperforms the state-of-the-art models by margins of 5.8%-9.4% in ROUGE metrics on method name generation after some adjustments on the structure. Empirically, we find the method name generation task depends on more local information than global, and the code comment generation task is in contrast.

In 27 in-depth, semi-structured interviews with owners, maintainers, and contributors from a diverse set of open source projects, we investigate their security and trust practices. For this, we explore projects' behind-the-scene processes, provided guidance & policies, as well as incident handling & encountered challenges. We find that our participants' projects are highly diverse both in deployed security measures and trust processes, as well as their underlying motivations. Based on our findings, we discuss implications for the open source software ecosystem and how the research community can better support open source projects in trust and security considerations. Overall, we argue for supporting open source projects in ways that consider their individual strengths and limitations, especially in the case of smaller projects with low contributor numbers and limited access to resources.","2022","2025-05-05 17:08:57","2025-05-05 17:08:57","","1880-1896","","NA","NA","","","","IEEE Symposium on Security and Privacy","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 978-1-6654-1316-9 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Literature Review Highlighting the problem, we cite research related to using undergraduates as participants, pedagogical value of these experiences, and current trends in software distribution. We then provide evidence of successful implementation of open-source software (OSS) in educational settings, and conclude with OSS options capable of addressing the problem of access. Teaching Implications By providing students research experiences, both as a researcher and as a participant, we enhance their understanding of this process.

The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the “institutional design” of the ASF could aid in producing the OSS public good by providing services that projects require.","2022","2025-05-05 17:08:58","2025-05-05 17:08:58","","64-77","","1","16","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: Unit 3N, 6 Osborn Street, LONDON, E1 6TD, ENGLAND Publisher: UBIQUITY PRESS LTD","","","","institutional analysis; open source software; commons; public goods; cost-benefit analysis; common-pool resource; \n policy analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

In most ecological studies, only a single similarity cutoff value is used for sequence identification. This is not sufficient since the most commonly used DNA markers are known to vary widely in terms of inter- and intraspecific variability. We address this problem by presenting a new tool, dnabarcoder, to predict local similarity cutoffs and measure the resolving powers of a biomarker for sequence identification for different clades of fungi. It was shown that the predicted similarity cutoffs varied significantly between the clades of a recently released ITS DNA barcode data set from the CBS culture collection of the Westerdijk Fungal Biodiversity Institute. When classifying a large public fungal ITS data set-the UNITE database-against the barcode data set, the local similarity cutoffs assigned fewer sequences than the traditional cutoffs used in metabarcoding studies. However, the obtained accuracy and precision were significantly improved. Our study showed that it might be better to extract the ITS region from the ITS barcodes to optimize taxonomic assignment accuracy. Furthermore, 15.3, 25.6, and 26.3% of the fungal species of the barcode data set were indistinguishable by full-length ITS, ITS1, and ITS2, respectively. Except for these indistinguishable species, the resolving powers of full-length ITS, ITS1, and ITS2 sequences were similar at the species level. Nevertheless, the complete ITS region had a better resolving power at higher taxonomic levels.","2022-10","2025-05-05 17:08:58","2025-05-05 17:08:58","","2793-2809","","7","22","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this study, our objective was to advance the practicality of drug-coated floss as an intra gum pocket drug delivery system. The initial design of this delivery system has been previously reported by us. Here, we advance the concept further through in vitro and in vivo evaluation. A floss piece was dip coated in the middle section with model molecules leaving free ends for holding. Porcine gum tissues were used ex vivo and in vivo to evaluate the coated floss, including effect of coating thickness on delivery efficiency, ability to deliver more than one type of molecule (one hydrophilic and one hydrophobic), mechanical properties using a scratch test, and finally retention of delivered material in vivo in the porcine model. After reaching a certain coating thickness, the delivery efficiency of the coated floss decreased, indicating the presence of an optimal coating thickness. Hydrophobic and hydrophilic molecules were successfully coated and delivered with high efficiency into gum pockets. The scratch test indicated that the coatings were resilient. Lastly, the in vivo analysis showed that the drug coating was delivered into the porcine gum pocket with about 65% efficiency, and the coatings could maintain extended residency within the gum pocket despite the native adverse environment of the oral cavity. Overall, this data shows that drug-coated floss can act as a drug delivery vehicle and has potential to provide a minimally invasive and practical method for the delivery of drugs into the gum pockets.","2022-06-29","2025-05-05 17:08:58","2025-05-05 17:08:58","","28663-28670","","25","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1155 16TH ST, NW, WASHINGTON, DC 20036 USA Publisher: AMER CHEMICAL SOC","","","","floss; coated; drug; gingivitis; gum; mouth; oral cavity","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The purpose of this study is to explore the status quo of educational application of FOSS and the trends from international perspectives and its implications for higher education in Hong Kong. Design/methodology/approach The method of cluster analysis was used in this study. The Web of Science database was used as the data source and all relevant literature for the year 2010-2020 on the theme of “FOSS” was collected for analysis. The information visualization software CiteSpace was used for citation visualization analysis, revealing the research results of FOSS worldwide, including hot spots and development trends. Findings This paper found that FOSS has become an important research area and is playing an important role in the reform and development of education. Meanwhile, the development and application of FOSS have regional imbalances and strong differentiation, including the educational sector. The paper also found that although FOSS has entered the stage of interdisciplinary development, the research and development of FOSS in the field of education is insufficient, which poses a huge challenge to decision-makers, teachers and students. Originality/value Implications for higher education in Hong Kong including: attach importance to and vigorously promote FOSS research and practice to benefit more teachers and students; teachers and students need to be trained for acquiring the awareness and skills of FOSS applications and formulate different strategies; the government should provide greater support to formulate and implement a short and middle-term development plan to facilitate the application of FOSS; and Hong Kong higher education institutions may strengthen exchanges and cooperation with counterparts around the world to jointly promote the development of FOSS.

A fork is a copy of the original repository that can evolve independently from the parent repository, allowing developers to experiment with a code base or test new features without the danger of affecting the original project. A fork can result in changes that are pushed back to the original project or even evolve into an independent project. Some projects tend to be forked extensively to the point where their forks are also forked and form families of projects. In this work, we explore the motivation, the practices and the culture of forking open-source software repositories. In particular, we study how forks evolve compared to the parent repository, how they are related to pull requests, how they contribute back to the parent, and how dependencies, in terms of libraries or external modules defined in a build script, are shared or differ within project families.

The physicochemical properties indicated that the nanoemulsion-based edible film (NEF) improved the morphology of FF and reduced the crystallinity of the film by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water vapor permeability increased gradually and rose to only 0.99% after 5 h, resulting in the water activity of FF at a low level (<= 0.51) during the storage period. The TPP inside was released at a constant rate (<= 18.10%) on the surface, and such a rate was accelerated in the simulated gastrointestinal environment, especially in intestine reaching 60.12% after 5 h of digestion. Besides, the effect of NEF on the flavor was also evaluated and the contents of ketones, phenols, and pyrazines increased, which displayed a regulating effect on the overall flavor of FF by blocking the external moisture and suppressing the microorganism activity.

Our brief review on free and open source software (FOSS) packages points out the existence of software offering a wide range of functionality, all the way from approximate semiempirical calculations with tight-binding density functional theory to sophisticated ab initio wave function methods such as coupled-cluster theory, covering both molecular and solid-state systems. Combined with the remarkable increase in the computing power of personal devices, which now rivals that of the fastest supercomputers in the world in the 1990s, we demonstrate that a decentralized model for teaching computational chemistry is now possible thanks to FOSS packages, enabling students to perform reasonable modeling on their own computing devices in the bring your own device (BYOD) scheme. FOSS software can be made trivially simple to install and keep up to date, eliminating the need for departmental support, and also enables comprehensive teaching strategies, as various algorithms' actual implementations can be used in teaching. We exemplify what kinds of calculations are feasible with four FOSS electronic structure programs, assuming only extremely modest computational resources, to illustrate how FOSS packages enable decentralized approaches to computational chemistry education within the BYOD scheme. FOSS also has further benefits driving its adoption: the open access to the source code of FOSS packages democratizes the science of computational chemistry, and FOSS packages can be used without limitation also beyond education, in academic and industrial applications, for example.

Extracting and analyzing useful plant phenotypic traits from hyperspectral images represents a major bottleneck for plant science and breeding communities. This study aims to present a stand-alone easy-to-use software platform called HSI-PP to process and analyze hyperspectral images for high-throughput plant phenotyping. The HSI-PP software integrates pre-processing, feature extraction, and modeling functions. The application of HSI-PP is exemplified by investigating the response of different Arabidopsis thaliana genotypes to drought stress, and the impact of various imaging angles on predicting the canopy nitrogen content (CNC) of oilseed rape (Brassica napus L.). The results showed that HSI-PP can process 10 GB on an ordinary PC in time ranging from 30 to 73 min according to image size and the complexity of the pipeline. HSI-PP extracted multiple phenotyping traits (spectral, textural, and morphological) of Arabidopsis thaliana from a large image dataset (104 GB) within five hours. The fusion of these features achieved higher accuracy (94%) than only using spectral information (85%) as early as day 4 after drought stress treatment. For oilseed rape, about 384 GB image data was processed within eighteen hours, and it was found that the tilted imaging angle of 75 had the optimized PLSR fitting (0.83) to the ground truth. The results demonstrate that HSI-PP is a stand-alone, automated, and open-source hyperspectral image processing platform adapted to various applications in plant phenotyping without requiring professional programming skills to serve the plant research community.","2022-09","2025-05-05 17:09:00","2025-05-05 17:09:00","","NA","","NA","200","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although the question has been identified as an interesting problem by the software community in online forums, it has not been investigated yet in adequate depth and scale, since the process of identifying the exact point in time when a vulnerability was introduced is particularly cumbersome. In this paper, we provide an automatic approach for accurately estimating how long vulnerabilities remain in the code (their lifetimes). Our method relies on the observation that while it is difficult to pinpoint the exact point of introduction for one vulnerability, it is possible to accurately estimate the average lifetime of a large enough sample of vulnerabilities, via a heuristic approach. With our approach, we perform the first large-scale measurement of Free and Open Source Software vulnerability lifetimes, going beyond approaches estimating lower bounds prevalent in previous research. We find that the average lifetime of a vulnerability is around 4 years, varying significantly between projects (similar to 2 years for Chromium, similar to 7 years for OpenSSL). The distribution of lifetimes can be approximately described by an exponential distribution. There are no statistically significant differences between the lifetimes of different vulnerability types when considering specific projects. Vulnerabilities are getting older, as the average lifetime of fixed vulnerabilities in a given year increases over time, influenced by the overall increase of code age. However, they live less than non-vulnerable code, with an increasing spread over time for some projects, suggesting a notion of maturity that can be considered an indicator of quality. While the introduction of fuzzers does not significantly reduce the lifetimes of memory-related vulnerabilities, further research is needed to better understand and quantify the impact of fuzzers and other tools on vulnerability lifetimes and on the security of codebases.","2022","2025-05-05 17:09:01","2025-05-05 17:09:01","","359-376","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: USENIX Assoc; Meta; Google; NSF; Baidu; Chainlink; IBM; Intel Secur; Red\n Canary; Mercari; Paloalto; Technol Innovat Inst ISBN: 978-1-939133-31-1 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To observe these relationships, we conducted a hypothesis-testing questionnaire-type survey involving 200 software development experts and professionals working at 60 multinational COSS companies. Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model. Therefore, COSS companies may need to prioritize software quality as it is the most critical variable impacting the success of COSS companies.","2022","2025-05-05 17:09:01","2025-05-05 17:09:01","","46490-46503","","NA","10","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA Publisher: IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC","","","","Open source software; Software; Companies; Software quality; company success; Integrated circuits; intellectual capital; Knowledge based systems; software\n quality; Commercial\n open-source software; Knowledge\n management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project's capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of subtopics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project's overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.","2022","2025-05-05 17:09:01","2025-05-05 17:09:01","","NA","","NA","NA","","","","OpenSym '22","","","","","","English","","","","","","","Backup Publisher: Univ Rey Juan Carlos; Vicerrectorado Extens Univ; GsyC/LibreSoft Res\n Grp; Programamos.es; John Ernest Fdn; ACM In Cooperat; SIGSOFT; SIGWEB ISBN: 978-1-4503-9846-6 Place: 1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES Publisher: ASSOC COMPUTING MACHINERY","","","","Health; Open Source Software; Sustainability; Software Ecosystem; \n Software Quality","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This paper studies (i) types of modifications that may affect vulnerable open-source dependencies and (ii) their impact on the performance of vulnerability scanners. Through an empirical study on 7,024 Java projects developed at SAP, we identified four types of modifications: re-compilation, re-bundling, metadata-removal and re-packaging. In particular, we found that more than 87 percent (56 percent, resp.) of the vulnerable Java classes considered occur in Maven Central in re-bundled (re-packaged, resp.) form. We assessed the impact of these modifications on the performance of the open-source vulnerability scanners OWASP Dependency-Check (OWASP) and Eclipse Steady, GitHub Security Alerts, and three commercial scanners.

In contrast to shotgun proteomics, proteins/peptides can be detected directly from biological tissues and correlated to its morphology leading to a gain of crucial clinical information. However, direct identification of the detected molecules is currently challenging for MALDI-IMS, thereby compelling researchers to use complementary techniques and resource intensive experimental setups. Despite these strategies, sufficient information could not be extracted because of lack of an optimum data combination strategy/software. Here, we introduce a new open-source software ImShot that aims at identifying peptides obtained in MALDI-IMS. This is achieved by combining information from IMS and shotgun proteomics (LC-MS) measurements of serial sections of the same tissue. The software takes advantage of a two group comparison to determine the search space of IMS masses after deisotoping the corresponding spectra. Ambiguity in annotations of IMS peptides is eliminated by introduction of a novel scoring system that identifies the most likely parent protein of a detected peptide in the corresponding IMS dataset. Thanks to its modular structure, the software can also handle LC-MS data separately and display interactive enrichment plots and enriched Gene Ontology terms or cellular pathways. The software has been built as a desktop application with a conveniently designed graphic user interface to provide users with a seamless experience in data analysis. ImShot can run on all the three major desktop operating systems and is freely available under Massachusetts Institute of Technology license.","2022-06","2025-05-05 17:09:02","2025-05-05 17:09:02","","NA","","6","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

By identifying problems before they arise in production, it enhances the quality of the code. Finding the best reviewer for a code change, however, is extremely challenging especially in large scale, especially open source software stacks with cross functioning designs and collaborations among multiple developers and teams. Additionally, a review by someone who lacks knowledge and understanding of the code can result in high resource consumption and technical errors. The reviewers who have the specialty in both functioning (domain knowledge) and non-functioning areas of a commit are considered as the most qualified reviewer to look over any changes to the code. Quality attributes serve as the connection among the user requirements, delivered function description, software architecture and implementation through put the entire software stack cycle. In this study, we target on auto reviewer assignment in large scale software stacks and aim to build a self-learning, and self-correct platform for intelligently matching between a commit based on its quality attributes and the skills sets of reviewers. To achieve this, quality attributes are classified and abstracted from the commit messages and based on which, the commits are assigned to the reviewers with the capability in reviewing the target commits. We first designed machine learning schemes for abstracting quality attributes based on historical data from the OpenStack repository. Two models are built and trained for automating the classification of the commits based on their quality attributes using the manual labeling of commits and multi-class classifiers. We then positioned the reviewers based on their historical data and the quality attributes characteristics. Finally we selected the recommended reviewer based on the distance between a commit and candidate reviewers. In this paper, we demonstrate how the models can choose the best quality attributes and assign the code review to the most qualified reviewers. With a comparatively small training dataset, the models are able to achieve F-1 scores of 77% and 85.31%, respectively.","2022","2025-05-05 17:09:03","2025-05-05 17:09:03","","NA","","NA","NA","","","","IEEE ACM International Conference on Automated Software Engineering","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; Meta; IBM; Ford; Huawei; Google; IEEE Comp\n Soc; IEEE Tech Council Software Engn; Special Interest Grp Software\n Engn; ACM SIGAI; Oakland Univ, Sch Engn & Comp Sci ISBN: 978-1-4503-9475-8 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Machine Learning; Code Review; Commit Classification; Large-scale; MPNet; Open-source","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within this literature, polycentric urban regions are commonly defined as territories that have multiple, proximately located (sub)centers and are characterized by balanced urban development. However, analytical-operational frameworks to identify and classify PURs are often ad hoc efforts to answer a specific research question and underlying work is often shelved rather than shared and/or made accessible. As a result, challenges associated with generalizability, reproducibility, and replicability clearly loom large in the urban polycentricity literature. Against this backdrop, this article describes the discrepancy between a rich debate on polycentricity and the paucity of tools enabling the disambiguation and reproducibility of results claimed by various authors around this polysemic concept. We present an online and open tool-PURban-that brings together the major analytical-operational frameworks and data sets in urban polycentricity research and allows parametrizing key operational choices. To illustrate the tool, we demonstrate how it facilitates the identification, mapping and analysis of degrees of morphological polycentricity in European urban systems. We conclude by reflecting on how this tool can act as a catalyst for future research on urban polycentricity.","2022-07","2025-05-05 17:09:03","2025-05-05 17:09:03","","583-598","","3, SI","54","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This inherent complexity, however, does not mean that the social world is chaotic, random, or unstructured. Rather, structural forms do emerge and co-exist in social settings. It is the emergence, maintenance, and decay of these structures that allows researchers to detect temporary stability and provides them with the means to make predictions about continuity and change in social dynamics. Arguably then, the main challenge in the study of the social world consist of developing robust and consistent strategies or tools capable of tracing, mapping, or retrieving these structural forms in order to ultimately model this social complexity. Accordingly, the overarching purpose of this study consists of addressing this analytic and methodological challenge by proposing a groundbreaking analytic framework, and its corresponding software application, designed to extract temporal and dynamic structures in the social world relying on complex realism, complex systems, dynamic temporal network analyses, and data science and visualization techniques. Together, these frameworks constitute the foundations of Mapping, Organizing, and Visualizing Interdependent Events (MOVIE), an analytic framework [and software application] designed to ease the understanding of, individually-produced or interactively-generated, events and knowledge evolution, by tracing and recreating the processes that may have affected participants' experiences, outcomes, and standpoints. To demonstrate MOVIE's performance and rigor in capturing and recreating the dynamic complexity of micro-level interactions, the analyses relied on publicly available data sources on foreign policy and conflict resolution. All data elements and tools are provided with this study to make these analyses fully transparent and reproducible. MOVIE can trace/recreate the temporal elements embedded in existing qualitative databases (e.g. those generated with NVivo/MAXQDA/Atlas.ti), even if they were created without considering their dynamic time-evolving features, whose meaning-building relevance may help inform policy planning and action.","2022-11","2025-05-05 17:09:03","2025-05-05 17:09:03","","263","","3","15","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Software; Maps; Time; Social Sciences: Comprehensive Works; Conflict resolution; Foreign policy; Methodological problems; Motion pictures; Social dynamics; Social systems; Data; Policy making","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The results are compared with experimental data and CFD using the commercial software Fluent, both previously reported in the open literature. This work studies the fluid flow pattern around a tube with six 45-degree-angled fins, and the working fluid, air, is considered as an incompressible fluid. Special attention is paid to calculating the pressure coefficient distribution for the internal and external surfaces of the inclined fins. Open-source platforms allow researchers to visualize how the airflow interacts with the cylinder and the fin surfaces to form a fluid structure, formerly known as a horseshoe vortex system. The findings of the analysis of flow dynamics in the channel between inclined fins and in the wake help explain the results obtained in experimental tests and are relevant for the configuration of a bank of tubes with inclined fins.","2022-08","2025-05-05 17:09:04","2025-05-05 17:09:04","","NA","","8","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Although the quality of developers' contributions should be the only factor influencing the evaluation of the contributions to OSS projects, recent studies have shown that diversity issues are correlated with the acceptance or rejection of developers' contributions. Objective: This paper assists this emerging state-of-the-art body on diversity research with the first empirical study that analyzes how developers' perceptible race and ethnicity relates to the evaluation of the contributions in OSS. We also want to create awareness of the racial and ethnic diversity in OSS projects. Methodology: We performed a large-scale quantitative study of OSS projects in GitHub. We extracted the developers' perceptible race and ethnicity from their names in GitHub using the Name-Prism tool and applied regression modeling of contributions (i.e, pull requests) data from GHTorrent and GitHub. Results: We observed that (1) among the developers whose perceptible race and ethnicity was captured by the tool, only 16.56 percent were perceptible as Non-White developers; (2) contributions from perceptible White developers have about 6-10 percent higher odds of being accepted when compared to contributions from perceptible Non-White developers; and (3) submitters with perceptible non-white races and ethnicities are more likely to get their pull requests accepted when the integrator is estimated to be from their same race and ethnicity rather than when the integrator is estimated to be White. Conclusion: Our initial analysis shows a low number of Non-White developers participating in OSS. Furthermore, the results from our regression analysis lead us to believe that there may exist differences between the evaluation of the contributions from different perceptible races and ethnicities. Thus, our findings reinforce the need for further studies on racial and ethnic diversity in software engineering to foster healthier OSS communities.","2022-08-01","2025-05-05 17:09:04","2025-05-05 17:09:04","","2955-2968","","8","48","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; GitHub; Ethnicity; software development; open source software; Race; Software engineering; Open-source software; Tools; Psychology; Regression analysis; Multiculturalism; Gender issues; Software development management; Diversity; Cultural differences; Developer; Empirical analysis; Ethnic group; Integrators; Multiculturalism & pluralism; Computers–Software; ethnicity diversity; Perceptible race","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The DRS can then be aggregated across a project as a derived vulnerability assessment, we call this the Computational Vulnerability Assessment Score (CVAS). The CVAS represents the correlation between the Developer Risk score across projects and vulnerabilities attributed to those projects. We believe this to be a contribution in trying to quantify risk introduced by specific developers across open source projects. Both of the risk scores, those for contributors and projects, are derived from an amalgamation of data, both from GitHub and outside GitHub.

But many OSS projects do not become sustainable, resulting in abandonment and even risks for the world's digital infrastructure. Prior work has looked at the reasons for this mainly from two very different perspectives. In software engineering, the focus has been on understanding success and sustainability from the socio-technical perspective: the OSS programmers' day-to-day activities and the artifacts they create. In institutional analysis, on the other hand, emphasis has been on institutional designs (e.g., policies, rules, and norms) that structure project governance. Even though each is necessary for a comprehensive understanding of OSS projects, the connection and interaction between the two approaches have been barely explored.In this paper, we make the first effort toward understanding OSS project sustainability using a dual-view analysis, by combining institutional analysis with socio-technical systems analysis. In particular, we (i) use linguistic approaches to extract institutional rules and norms from OSS contributors' communications to represent the evolution of their governance systems, and (ii) construct socio-technical networks based on longitudinal collaboration records to represent each project's organizational structure. We combined the two methods and applied them to a dataset of developer digital traces from 253 nascent OSS projects within the Apache Software Foundation (ASF) incubator. We find that the socio-technical and institutional features relate to each other, and provide complimentary views into the progress of the ASF's OSS projects. Refining these combined analyses can help provide a more precise understanding of the synchronization between the evolution of institutional governance and organizational structure.","2022-11","2025-05-05 17:09:05","2025-05-05 17:09:05","","NA","","CSCW2","6","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","institutional design; OSS sustainability; socio-technical systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem.

Commonly, they emerge from one product when there is a need to create tailored variants, or from existing variants created in an ad-hoc way once their separated maintenance and evolution become challenging. Despite the vast literature about re-engineering systems into SPLs and related technical approaches, there is a lack of detailed analysis of the process itself and the effort involved. In this paper, we provide and analyze empirical data of the extraction processes of two open-source case studies, namely ArgoUML and Phaser. Both cases emerged from the transition of a monolithic system into an SPL. The analysis relies on information mined from the version control history of their respective source-code repositories and the discussion with developers that took part in the process. Unlike previous works that focused mostly on the structural results of the final SPL, the contribution of this study is an in-depth characterization of the processes. With this work, we aimed at providing a deeper understanding of the strategies for SPL extraction and their implications. Our results indicate that the source code changes can range from almost a fourth to over half of the total lines of code. Developers may or may not use branching strategies for feature extraction. Additionally, the problems faced during the extraction process may be due to lack of tool support, complexity on managing feature dependencies and issues with feature constraints. We made publicly available the datasets and the analysis scripts of both case studies to be used as a baseline for extractive SPL adoption research and practice.","2022-07","2025-05-05 17:09:05","2025-05-05 17:09:05","","NA","","4","27","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

J.","PING-Mapper: Open-Source Software for Automated Benthic Imaging and Mapping Using Recreation-Grade Sonar","NA","","NA","10.1029/2022EA002469","NA","The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation-grade side-scan sonar systems are increasingly used to aid scientific inquiries in aquatic environments due to their relative low-cost, ease of operation, low-weight, and ease of mounting on a variety of vessels. However, existing procedures and software for post-processing these data are either limited, closed source, or fail on data from new sonar models, limiting the development of reproducible workflows. Here, we present PING-Mapper, an open-source and freely available side-scan sonar post-processing toolset for processing and mapping sonar recordings from popular Humminbird instruments. The modular software automatically: (a) decodes sonar recordings from any Humminbird system, (b) exports ping attributes from every sonar channel, (c) uses sonar sensor depth for water column removal, and (d) exports sonogram tiles and georectified mosaics. Sonar channels are processed in parallel for quick decoding and metadata extraction. Major processing wokflows, including georectification and image export, are optimized to scale with computing resources. The software has been extensively tested using data from several rivers of varying character and distribution of depths, but could also be used in estuarine and lacustrine environments. Usage of PING-Mapper is illustrated in three case studies focused on mapping large woody debris, bathymetric mapping, and visual interpretation and mapping of substrates for selected reaches of the Pearl and Pascagoula river systems in Mississippi. Plain Language Summary Side-scan sonar instruments provide a way to survey and visualize the bottom of rivers, lakes, or oceans. Since the early 2000s, companies catering predominantly to anglers have manufactured recreation-grade side-scan sonar systems to aid fishermen in locating fish and identifying potential hazards. Scientists seeking to understand and manage aquatic habitats used these systems to create grayscale images of water bottoms because they are inexpensive, easy to operate, and require minimal mounting equipment on the boat. Software has been created by companies to process these data, but the underlying processing workflow and computer code are not publicly available, making it difficult to reproduce and compare results across studies. Other publicly available approaches and software are either outdated, not maintained, or not free. That is why we made PING-Mapper, a freely available software developed in an increasingly popular programming language called Python. We designed the software to work on any computer to export the data sets quickly and efficiently. The scientific use of exported data sets is demonstrated with three case studies focused on locating and mapping targets (specifically large trees and branches), creating depth maps, and visually discerning the distributions of common substrates, such as sand and cobble.","2022-09","2025-05-05 17:09:05","2025-05-05 17:09:05","","NA","","9","9","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Precision fertilization and irrigation is an effective method to solve this problem. In order to precisely control plant fertilization and irrigation, a monitoring system is designed and implemented using open-source software, loose communication structure, industrial control computer (IPC), programmable logic controller (PLC), and control and monitoring devices. The control command management subsystem of the system's upper computer is built using GoWin IPC, cloud server, mobile devices, and 4G wireless network. Each application running in the upper computer is developed using open-source software such as PostgreSQL, Smobiler, etc. The fertilization and irrigation monitoring subsystem of the lower computer was built using HollySys PLC model LE5107L and different sensors for various data parameters as control units. The system allows real-time remote monitoring and control of agricultural precision fertilization and irrigation through mobile applications, with an average communication delay of 1.45 s between the upper and lower units, and less than 3 s overall, allowing for longterm stable communication. The current system can adapt to the variable environment in the field and has been operating stably in the field for 2 months.

In this era where most of the similar processes are automated, manual application may result in excessive time consumption, unnecessary use of qualified work-force, and is also open to error. A software that automates these processes for neuropsychological tests used for dementia assessment may overcome these issues. Methods: We aimed to develop a free, open source software not requiring specialized training, which would optimise the calculation, preparation of personal reports and archiving processes of neuropsychological tests, hence would easily be incorporated in to the daily work of psychologists. We've used Python 3.6 as the programming language, and JSON was used as the data interchange format to allow for personal alterations in the content. The tests were selected among those which are in common use for neuropsychological evaluation of adults in Turkey, with available norm values. (Funding: TUBITAK 214S048). Results: PsiNorm was developed, comprising widely used standardized tests for cognitive evaluation of adults in Turkey. The software is lightweight, compatible with most common operating systems, and easy-to-use. We've shown that Psinorm significantly reduced the time required for calculation of percentiles and norms as well as for producing a draft report. The reports are prepared in.txt format and the databases are prepared in MS Excel ve CSV formats. PsiNorm is available freely at psinorm.org. Conclusion: PsiNorm is a free, open-source software which is available for researchers and clinicians who perform neuropsychological tests. PsiNorm provides significant time and labor-force benefits, is easy-to-use and can be customized by the user.","2022","2025-05-05 17:09:05","2025-05-05 17:09:05","","255-262","","4","33","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The morphometric quantification of these networks is essential to study the cellular phenotype. Commonly, the quantitative measurements are performed on 2D projections of the image stack, resulting in the loss of information in the third dimension. Currently available 3D image analysis tools rely on manual interactions with the software and are therefore not feasible for large datasets. Findings Here we present Qiber3D, an open-source image processing toolkit. The software package includes the essential image analysis procedures required for image processing, from the raw image to the quantified data. Optional pre-processing steps can be switched on/off depending on the input data to allow for analyzing networks from a variety of sources. Two reconstruction algorithms are offered to meet the requirements for a wide range of network types. Furthermore, Qiber3D's rendering capabilities enable the user to inspect each step of the image analysis process interactively to ensure the creation of an optimal workflow for each application. Conclusions Qiber3D is implemented as a Python package, and its source code is freely available at https://github.com/theia-dev/Qiber3D. The toolkit was designed using a building block principle to enable the analysis of a variety of structures, such as vascular networks, neuronal structures, or scaffolds from numerous input formats. While Qiber3D can be used interactively in the Python console, it is aimed at unsupervised automation to process large image datasets efficiently.","2022","2025-05-05 17:09:06","2025-05-05 17:09:06","","NA","","NA","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While this model lowers the barrier to entry for OSS developers by synthesizing, automating and optimizing the contribution process, coordination among an increasing number of contributors remains as a challenge due to the asynchronous and self-organized nature of distributed development. In particular, duplicate contributions, where multiple different contributors unintentionally submit duplicate pull requests to achieve the same goal, are an elusive problem that may waste effort in automated testing, code review and software maintenance. While the issue of duplicate pull requests has been highlighted, to what extent duplicate pull requests affect the development in OSS communities has not been well investigated. In this paper, we conduct a mixed-approach study to bridge this gap. Based on a comprehensive dataset constructed from 26 popular GitHub projects, we obtain the following findings: (a) Duplicate pull requests result in redundant human and computing resources, exerting a significant impact on the contribution and evaluation process. (b) Contributors' inappropriate working patterns and the drawbacks of their collaborating environment might result in duplicate pull requests. (c) Compared to non-duplicate pull requests, duplicate pull requests have significantly different features, e.g., being submitted by inexperienced contributors, being fixing bugs, touching cold files, and solving tracked issues. (d) Integrators choosing between duplicate pull requests prefer to accept those with early submission time, accurate and high-quality implementation, broad coverage, test code, high maturity, deep discussion, and active response.

Owing to the uncertainty and complexity of OSS development, testing and debugging environments, OSS are completed dynamically. When detected faults are removed for OSS, they are likely to introduce new faults. Moreover, under the different OSS debugging environments, fault introduction will show different changes. For example, the fault introduction rate shows a decrease change, or increasing first and then decreasing change over time. Considering the complex and dynamic changes in fault introduction, an OSS reliability model that fault introduction obeys a generalized inflection S-shaped distribution is proposed in this paper. Experimental results indicate that the fitting and predictive performance of the proposed model is good. The established model in this paper can adapt the dynamical and complicated changes of fault introduction during OSS debugging.

While nowadays new objects are mostly detected in larger sky surveys, several follow-up observations are usually needed for each object to improve the accuracy of orbit determination. In particular objects orbiting close to Earth, so called Near-Earth Objects (NEOs) are of special concern as a small but not negligible fraction of them can have a non-zero impact probability with Earth. Additionally, the observation of manmade space debris and tracking of satellites falls in the same class measurements. Telescopes for these follow-up observations are mainly in a aperture class between 1 m down to approximately 25 cm. These telescopes are often hosted by amateur observatories or dedicated companies like 6ROADS specialized on this type of observation. With upcoming new NEO search campaigns by very wide field of view telescopes, like the Vera C. Rubin Observatory, NASA's NEO surveyor space mission and ESA's Flyeye telescopes, the number of NEO discoveries will increase dramatically. This will require an increasing number of useful telescopes for follow-up observations at different geographical locations. While well-equipped amateur astronomers often host instruments which might be capable of creating useful measurements, both observation planning and scheduling, and also analysis are still a major challenge for many observers. In this work we present a fully robotic planning, scheduling and observation pipeline that extends the widely used open-source cross-platform software KStars/Ekos for Instrument Neutral Distributed Interface (INDI) devices. The method consists of algorithms which automatically select NEO candidates with priority according to ESA's Near-Earth Object Coordination Centre (NEOCC). It then analyses detectable objects (based on limiting magnitudes, geographical position, and time) with preliminary ephemeris from the Minor Planet Center (MPC). Optimal observing slots during the night are calculated and scheduled. Immediately before the measurement the accurate position of the minor body is recalculated and finally the images are taken.

The modeling approach considers residual gravity field functionals generated by the well-known remove-compute-restore (RCR) technique where the long and short wavelength parts of the gravity signal are provided by a global geopotential model (GGM) and digital terrain model (DTM), respectively. A new data-adaptive network design methodology called k-SRBF is used to construct a network of SRBFs. The appropriate bandwidths (depths) are chosen using the generalized cross-validation (GCV) technique. The unknown SRBFs coefficients are estimated by applying the least-squares method where the extended Gauss Markov Model (GMM) with additional prior information is applied if the normal equation matrix is ill-conditioned. In such a case, the optimal regularization parameter is determined by variance component estimation (VCE). By utilizing parallel processing in every stage of the RCR technique, including creating the design matrix, the computational time is remarkably decreased relative to the number of processors used in the modeling. The performance of the software has been tested and validated in the Auvergne test area (France) on the basis of real terrestrial gravity data. The differences between estimated and observed height anomaly points (GNSS/leveling) amount to about 3 cm in terms of standard deviation (STD) for all kernels indicating that the SRBF_Soft possesses the capability to be applied in regional gravity field modeling as an efficient and reliable software.","2022-06","2025-05-05 17:09:06","2025-05-05 17:09:06","","1341-1353","","2","15","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor performance status. A single agent chemotherapy was offered with the prevalence of oral metronomic vinorelbine. In the whole population, progression-free survival and overall survival ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. Limited evidence is available concerning the selection criteria and the outcomes of platinum unfit newly diagnosed advanced NSCLC patients receiving single-agent chemotherapy. We retrospectively collected data on consecutive, stage IIIB-IV, EGFR/ALK negative and PD-L1 < 50% NSCLC patients treated with first-line single agent chemotherapy. Baseline characteristics, outcome measures and toxicities were recorded, as well as criteria according to which treatment selection was made and what percentage of patients did not receive a first-line platinum-based chemotherapy. Two-hundred and twenty-one patients were included. Median age was 79 (range 56-92) years, M/F 165(74.6%)/56(25.4%), ECOG performance status (PS) 0/1/ >= 2 23(10.9%)/94(42.5%)/103(46.6%), with a median of two serious comorbidities. A median of 25% (range 10%-30%) of newly diagnosed NSCLC did not receive a first-line platinum combination. Clinical criteria according to which decision was made were older age (76.5%), comorbidities (72%), poor PS (55.2%) and familiar or social issues (10%). Single-agent treatment consisted of oral metronomic vinorelbine (MetV 78.6%), gemcitabine (Gem 10%), oral standard vinorelbine (Vin 8.2%) and other (O 3.2%). Median progression-free survival (PFS) and overall survival (OS) of single agent treatments ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. All grade toxicities did not differ among single agents, while grade 3-4 toxicities were less frequent with MetV. Up to 30% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor PS. An oral treatment was frequently proposed with MetV being the most frequent choice according to its safety profile.","2022-12","2025-05-05 17:09:06","2025-05-05 17:09:06","","NA","","24","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","elderly; low performance status; metronomic; single agent chemotherapy; non-small\n cell lung cancer","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it is time-consuming because of the bioinformatics processes involved, including sequence trimming, consensus sequence generation, and public database searches. We developed a simple and fully automated software that enabled species-level identification of NTM from trace files, SnackNTM (https://github.com/Young-gonKim/SnackNTM). Methods: JAVA programing language was used for software development. The SnackNTM diagnostic algorithm utilized 16S rRNA gene sequences, according to the Clinical & Laboratory Standards Institute guidelines, and an rpoB gene region was adjunctively utilized to narrow down the species. The software performance was validated using trace files of 234 clinical cases, comprising 217 consecutive cases and 17 additionally selected cases of unique species. Results: SnackNTM could analyze multiple cases at once, and all the bioinformatics processes required for sequence-based NTM identification were automatically performed with a single mouse click. SnackNTM successfully identified 95.9% (208/217) of consecutive clinical cases, and the results showed 99.0% (206/208) agreement with manual classification results. SnackNTM successfully identified all 17 cases of unique species. In a processing time comparison test, the analysis and reporting of 30 cases, which took 150 minutes manually, took only 40 minutes with SnackNTM. Conclusions: SnackNTM is expected to reduce the workload for NTM identification, especially in clinical laboratories that process large numbers of cases.","2022-03","2025-05-05 17:09:07","2025-05-05 17:09:07","","213-248","","2","42","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: A505-ASTERIUM SEOUL, 372 HANGANG-DAERO, YONGSAN-GU, SEOUL, 04323, SOUTH\n KOREA Publisher: KOREAN SOC LABORATORY MEDICINE","","","","Nontuberculous mycobacteria; NTM identification; rpoB; SnackNTM; 16S rRNA\n gene","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS is mainly developed by developers, volunteers, and users all over the world, but its reliability has been widely questioned. When OSS faults are detected, volunteers or users send them to developers by email or network. After the developer confirms the fault, it will be randomly assigned to the debugger who may be a developer, a volunteer, or a user. These open source community contributors also have the phenomenon of learning when removing faults. When the detected faults are removed, the number of introduced faults decreases gradually. Therefore, this study proposes a software reliability model with the decreasing trend of fault introduction in the process of OSS development and testing. The validity of the proposed model and the accuracy of estimating residual faults are verified by experiments. The proposed model can be used to evaluate the reliability and predict the remaining faults in the actual OSS development and testing process.","2022","2025-05-05 17:09:07","2025-05-05 17:09:07","","NA","","5","17","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, the use of biomaterials/scaffolds for maxillofacial bone regrowth has been attracting great interest from many surgical specialties and experts. Many approaches have been devised in order to create an optimal bone scaffold capable of achieving desirable degrees of bone integration and osteogenesis. Osteogenesis represents a complex physiological process involving multiple cooperating systems. A tight relationship between the immune and skeletal systems has lately been established using the concept of “osteoimmunology,” since various molecules, particularly those regulating immunological and inflammatory processes, are shared. Inflammatory mediators are now being implicated in bone remodeling, according to new scientific data. In this study, a profiler PCR array was employed to evaluate the expression of cytokines and chemokines in human adipose derived-mesenchymal stem cells (hASCs) cultured on porous hydroxylapatite (HA)/Collagen derived Bio-Oss((R))/Avitene scaffolds, up to day 21. In hASCs grown on the Bio-Oss((R))/Avitene biomaterial, 12 differentially expressed genes (DEGs) were found to be up-regulated, together with 12 DEG down-regulated. Chemokine CCL2, which affects bone metabolism, tested down-regulated. Interestingly, the Bio-Oss((R))/Avitene induced the down-regulation of pro-inflammatory inter-leukin IL-6. In conclusion, our investigation carried out on the Bio-Oss((R))/Avitene scaffold indicates that it could be successfully employed in maxillofacial surgery. Indeed, this composite material has the advantage of being customized on the basis of the individual patients favoring a novel personalized medicine approach.","2022-06-27","2025-05-05 17:09:07","2025-05-05 17:09:07","","NA","","NA","10","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: AVENUE DU TRIBUNAL FEDERAL 34, LAUSANNE, CH-1015, SWITZERLAND Publisher: FRONTIERS MEDIA SA","","","","chemokine; cytokine; immunomodulation; osteogenic differentiation; stem cells; \n biomaterial","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, according to the software version sequence, we construct the corresponding developer collaboration network of the Angular OSS community and then analyse this network's structural stability during network evolution. The results show that the network always presents an economical modular small-world structure during its evolution. The maintenance of the structure is related to a cohesive core, which is composed of two types of nodes (i.e., hubs and connectors). The hubs organize noncore nodes to form modules, while connectors facilitate the formation of inter-module connections. The overall results highlight the important role of core developers in the sustainable development of OSS communities and may provide a reference for community initiators to implement protection strategies for core developers.","2022-07-08","2025-05-05 17:09:07","2025-05-05 17:09:07","","NA","","7","17","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This trend, as well as technological advancements in the unmanned aerial vehicle (UAV) industry, have opened blue skies for both researchers and surveyors. In this study, we aimed to assess the quality of the sparse point cloud obtained with a consumer UAV and a FOSS. To achieve this goal, we also process the same image dataset with a commercial software package using its results as a term of comparison. Various analyses were conducted, such as the image residuals analysis, the statistical analysis of GCPs and CPs errors, the relative accuracy assessment, and the Cloud-to-Cloud distance comparison. A support survey was conducted to measure 16 markers identified on the object. In particular, 12 of these were used as ground control points to scale the 3D model, while the remaining 4 were used as check points to assess the quality of the scaling procedure by examining the residuals. Results indicate that the sparse clouds obtained are comparable. MicMac (R) has mean image residuals equal to 0.770 pixels while for Metashape (R) is 0.735 pixels. In addition, the 3D errors on control points are similar: the mean 3D error for MicMac (R) is equal to 0.037 m with a standard deviation of 0.017 m, whereas for Metashape (R), it is 0.031 m with a standard deviation equal to 0.015 m. The present work represents a preliminary study: a comparison between software packages is something hard to achieve, given the secrecy of the commercial software and the theoretical differences between the approaches. This case study analyzes an object with extremely complex geometry; it is placed in an urban canyon where the GNSS support can not be exploited.

This paper analyzes the governance of these organizations from the perspective of their structure and control, considering the development trajectory of three communitybased free software projects in Brazil. Results show that the constant need to produce modern technologies gives rise to external pressures that promote change - albeit temporary - in the governance of these projects, making them resemble a cathedral more than a bazaar. Governance does not follow a cycle of sequential improvement; it changes depending on the external organizational actors present, such as sponsors. This suggests the need for strategic and flexible governance to deal with the acquisition and allocation of organizational resources. Governance of the projects described here varies along a spectrum of (in)formality that allows both production models - cathedral or bazaar - to exist in the same organization at different periods.","2022-02","2025-05-05 17:09:08","2025-05-05 17:09:08","","1–17","","1","62","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Virtual communities; Open source; Transformation; Governance; Software development; Freeware; Resource allocation; Bureaucracy; Development programs; Business And Economics–Management","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In recent years, dose-surface maps (DSMs) have become increasingly popular for characterization of spatial dose distributions and identification of radiosensitive subregions for hollow organs. However, methodological variations and lack of open-source, publicly offered code-sharing between research groups have limited reproducibility and wider adoption. Purpose This paper presents rtdsm, an open-source software for DSM calculation with the intent to improve the reproducibility of and the access to DSM-based research in medical physics and radiation oncology. Methods A literature review was conducted to identify essential functionalities and prevailing calculation approaches to guide development. The described software has been designed to calculate DSMs from DICOM data with a high degree of user customizability and to facilitate DSM feature analysis. Core functionalities include DSM calculation, equivalent dose conversions, common DSM feature extraction, and simple DSM accumulation. Results A number of use cases were used to qualitatively and quantitatively demonstrate the use and usefulness of rtdsm. Specifically, two DSM slicing methods, planar and noncoplanar, were implemented and tested, and the effects of method choice on output DSMs were demonstrated. An example comparison of DSMs from two different treatments was used to highlight the use cases of various built-in analysis functions for equivalent dose conversion and DSM feature extraction. Conclusions We developed and implemented rtdsm as a standalone software that provides all essential functionalities required to perform a DSM-based study. It has been made freely accessible under an open-source license on Github to encourage collaboration and community use.","2022-11","2025-05-05 17:09:08","2025-05-05 17:09:08","","7327-7335","","11","49","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

GaugeCam Remote Image Manager-Educational 2 (GRIME2) is a mature, open-source commercial friendly software application that automatically detects and measures water level in laboratory and field settings. The software relies on a dedicated target background for water line detection and image calibration. The system detects the change in pixel gray scale values associated with the intersection of the water level at the target surface. Fiducials on the target background are used to precisely create a pixel to real world coordinate transfer matrix and to correct for camera movement. The presented software package implements the algorithms and automates the water level measurement process, annotation of images with result overlays, creation of animations, and output of results to files that can be further analyzed in a spreadsheet or with R or Python. These GRIME2 features are illustrated using imagery from a coastal marsh field site. Tradeoffs between workflow and algorithm complexity and ease of use are discussed and future improvements are identified with the intention that this Findable, Accessible, Interoperable, and Reusable-inspired software can be adopted, modified and improved by the user community. While image resolution, quality and other factors associated with field deployment (e.g., water surface roughness, sun glare, shadows, and bio-fouling) will have an impact on measurement quality, previous controlled laboratory testing that did not manifest these issues showed potential for accuracy of +/- 3 mm (Gilmore et al., 2013, ).","2022-08","2025-05-05 17:09:08","2025-05-05 17:09:08","","NA","","8","58","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; open source software; Quality assurance; Software; Software packages; Measurement; Imagery; Software development; Algorithms; Environmental; Laboratories; Workflow; Digital image processing; Annotations; Calibration; Coastal marshes; hydrology; image processing; Image processing; Image quality; Image resolution; Laboratory tests; pixel to world calibration; Pixels; Shadows; stage measurement; Surface roughness; Tidal marsh; Transfer matrices; Water; Water level; Water level measurement; Water levels; waterline detection; Earth Sciences–Hydrology","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this paper, we present a data set on GitHub Sponsors and conduct a data-driven study to analyze the participants of the program and the impact of sponsorships to developers' activities and their projects' outcomes and qualities. The results of our survey suggest that most developers state they will contribute more with sponsorships and provide some privilege for their sponsors. And through quantitative study, we find that developers make more contributions on GitHub after they got/offered sponsorships. Moreover, gaining sponsorship also has a weakly positive impact on developers' collaborators that did not get sponsorship.

A structural equation model (SEM) has been defined under the postulates of the Path-Goal leadership theory and Motivational Behaviour. This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader.

We develop a formal model where both volunteers (agents setting their agendas freely) and firm's employees (agents whose agenda is mostly set by their employer) participate in the creation of a common artifact. In this framework, we discuss how firms can influence the architecture of the emerging product to assure fast and performant development and a desirable distribution of innovative labor within the project team. We find that closing the project only to employees implies high speed and performance if employees are given autonomy in certain dimensions and are directed in others. In this case, however, we observe a trade-off in terms of ideal core-periphery division of labor on one side and development speed and performance on the other side. At the opposite extreme, creating a volunteer-only project can ease the trade-off but assures positive results only if the firm is able to set up an entry mechanism that “surgically” selects volunteers with specific preferences. A mixture of both employees and volunteers can strike a good balance, relaxing the two constraints.","2022-11-19","2025-05-05 17:09:10","2025-05-05 17:09:10","","1358-1386","","6","31","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Motivated by this potential, we model the partner recommendation as link prediction task from email data via network embedding methods. In this article, we introduce time-series snapshot network (TSSN) that is a mixture network to model the interactions among users and developers. Based on the established TSSN, we perform temporal biased walk (TBW) to automatically capture both temporal and structural information of the email network, i.e., the behavioral similarity between individuals in the OSS email network.

Materials and Methods: Sixty-eight patients who had difficulty in cannulation into the papilla located at the lower, left, or right side of the periampullary diverticulum upon endoscopic retrograde cholangiopancreatography (ERCP) were recruited at Taizhou Hospital from July 2016 to June 2020. A random number table was used to divide the patients into an intervention (with titanium clip-dental floss traction) group and a control group (n=34 in each group). Patients in both groups underwent ERCP. The cannulation time, cannulation success rate, incidence of postprocedural complications after ERCP, hospitalization time, and hospitalization expenses in the 2 groups were compared. Result: The cannulation time was 15.3 +/- 4.1 minutes in the intervention group, which was less than that in the control group (25.7 +/- 6.5 min). The cannulation success rate was 77 +/- 12.1% in the intervention group, which was higher than that in the control group (43 +/- 16.7%). Postprocedural complications occurred in 2 patients in the intervention group and 6 patients in the control group, with no significant differences. The hospitalization time and expenses were 3.8 +/- 2.6 days and 11.1 +/- 6 thousand yuan in the intervention group, respectively, and 6.1 +/- 3.7 days and 18.2 +/- 8 thousand yuan in the control group, respectively. The differences were statistically significant (P<0.05). Conclusion: Titanium clip-dental floss traction-assisting endoscopy achieved excellent efficacy in patients with difficulty in cannulation into the papilla located at the lower, left or right side of the periampullary diverticulum.

There are, however, situations where visual inspection may be difficult or impossible, especially in critical areas of bridges, such as the ceiling and corners. In this contribution, the authors acquire images using a prototype drone with a low-cost camera mounted upward over the body of the drone.

Typically, the developers create a stable branch for each old stable version, deploy security patches on the branch, and release fixed versions at regular intervals. As such, old-version applications in production environments are protected from the disclosed vulnerabilities in a long time. However, the rapidly growing number of OSS vulnerabilities has greatly strained this patch deployment model, and a critical need has arisen for the security community to understand the practice of security patch management across stable branches. In this work, we conduct a large-scale empirical study of stable branches in OSS projects and the security patches deployed on them via investigating 608 stable branches belonging to 26 popular OSS projects as well as more than 2,000 security fixes for 806 CVEs deployed on stable branches. Our study distills several important findings: (i) more than 80% affected CVE-Branch pairs are unpatched; (ii) the unpatched vulnerabilities could pose a serious security risk to applications in use, with 47.39% of them achieving a CVSS score over 7 (High or Critical Severity); and (iii) the patch porting process requires great manual efforts and takes an average of 40.46 days, significantly extending the time window for N-day vulnerability attacks. Our results reveal the worrying state of security patch management across stable branches. We hope our study can shed some light on improving the practice of patch management in OSS projects.","2022","2025-05-05 17:09:12","2025-05-05 17:09:12","","767-777","","NA","NA","","","","WWW '22","","","","","","NA","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGWEB; LIRIS; Univ Lyon; Inst Natl Sci\n Appliquees; Eurecom ISBN: 978-1-4503-9096-5 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","OSS Vulnerabilities; Patch Deployment Study; Security Patches","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The structure of the mitral and tricuspid valves in biventricular hearts has previously been shown to be associated with valve dysfunction. However, the three-dimensional (3D) structure of the entire unrepaired CAVC valve has not been quantified. Understanding the 3D structure of the CAVC may inform optimized repair.Methods: Novel open-source work flows were created in SlicerHeart for the modeling and quantification of CAVC valves on the basis of 3D echocardiographic images. These methods were applied to model the annulus, leaflets, and papillary muscle (PM) structure of 35 patients (29 with trisomy 21) with CAVC using trans -thoracic 3D echocardiography. The mean leaflet and annular shapes were calculated and visualized using shape analysis. Metrics of the complete native CAVC valve structure were compared with those of normal mitral valves using the Mann-Whitney U test. Associations between CAVC structure and atrioventricular valve regurgitation were analyzed.Results: CAVC leaflet metrics varied throughout systole. Compared with normal mitral valves, the left CAVC PMs were more acutely angled in relation to the annular plane (P < .001). In addition, the anterolateral PM was laterally and inferiorly rotated in CAVC, while the posteromedial PM was more superiorly and laterally rotated, relative to normal mitral valves (P < .001). Lower native CAVC atrioventricular valve annular height and annular height-to-valve width ratio before repair were both associated with moderate or greater left atrio-ventricular valve regurgitation after repair (P < .01).Conclusions: It is feasible to model and quantify 3D CAVC structure using 3D echocardiographic images. The results demonstrate significant variation in CAVC structure across the cohort and differences in annular, leaflet, and PM structure compared with the mitral valve. These tools may be used in future studies to catalyze future research intended to identify structural associations of valve dysfunction and to optimize repair in this vulnerable and complex population.

Different characteristics of bugs, such as severity, priority, and time to fix, provide a clear picture of an ITS. Nevertheless, such information may be misleading. For example, the exact time and the effort spent on a bug might be significantly different from the actual reporting time and the fixing time. Similarly, these values may be subjective, e.g., severity and priority values are assigned based on the intuition of a user or a developer rather than a structured and well-defined procedure. Hence, we explore the evolution of the bug dependency graph together with priority and severity levels to explore the actual triage process. Inspired by the idea of the “Wayback Machine “for the World Wide Web, we aim to reconstruct the historical decisions made in the ITS. Therefore, any bug prioritization or bug triage algorithms/scenarios can be applied in the same environment using our proposed ITS Wayback Machine. More importantly, we track the evolutionary metrics in the ITS when a custom triage/prioritization strategy is employed. We test the efficiency of the proposed algorithm using data extracted from three open-source projects. Our empirical study sheds light on the overlooked evolutionary metrics - e.g., overdue bugs and developers' loads - which are facilitated via our proposed past-event re-generator.

Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94% of the surveyed core developers agreed with our state model of inactivity; 71% and 79% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26%, with a similar to 54% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.","2022-05","2025-05-05 17:09:15","2025-05-05 17:09:15","","NA","","3","27","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER","","","","Retention; Disengagement; Abandonment; Open-source communities; Repository mining; \n Turnover","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article systematically maps, aggregates, and synthesizes the state-of-the-art on women's participation in OSS. It focuses on women contributors' representation and demographics, how they contribute, their motivations and challenges, and strategies employed by communities to attract and retain women. We identified 51 articles (published between 2000 and 2021) that investigated women's participation in OSS. We found evidence in these papers about who are the women who contribute, what motivates them to contribute, what types of contributions they make, challenges they face, and strategies proposed to support their participation. According to these studies, only about 5% of projects were reported to have women as core developers, and women authored less than 5% of pull-requests, but had similar or even higher rates of pull-request acceptances than men. Women make both code and non-code contributions, and their motivations to contribute include learning new skills, altruism, reciprocity, and kinship. Challenges that women face in OSS are mainly social, including lack of peer parity and non-inclusive communication from a toxic culture. We found 10 strategies reported in the literature, which we mapped to the reported challenges.

Its aim is to facilitate the management and configuration of the ES-MDA through several programming tools that help in the preparation of the different steps of ES-MDA. genES-MDA has a flexible workflow that can be easily adapted for the implementation of different variants of the ensemble Kalman filter and for the solution of generic inverse problems. This paper presents a description of the package and some application examples. genES-MDA has been tested in three synthetic case studies: the solution of the reverse flow routing for the estimation of the inflow hydrograph to a river reach using observed water levels and a calibrated forward model of the river system, the identification of a hydraulic conductivity field using piezometric observations and a known forward flow model, and the estimation of the release history of a contaminant spill in an aquifer from measured concentration data and a known flow and transport model.

To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (p < 0.0001, effect size = 0.84), student motivation (p < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (p < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner.

The present research aims to introduce a new architecture proposal for migrating traditional (automation) to smart (digitization) factories, implemented through open-source software. The proposed architecture is integrated, for the first time, by the interconnection of six main elements: cyber-physical systems, edge computing, artificial intelligence, cloud computing, data analytics, and cybersecurity; the research describes in detail their definitions, sub-elements, the interconnection between elements, and the minimum requirements for implementation. The test of the proposed smart factory was done through a scale smart factory pilot testing for a pick and place process, where the assembly of wood pieces from the geometric Tangram's puzzle was required; for this reason, the pilot testing includes a six-degree-of-freedom robot arm, a conveyor, a vision system, and a storage area. The case study conducted in this research allowed the assembly of four puzzles (fish, house, rocket, and swan) that were assembled with four different batches of pieces. The implementation allowed testing flexibility and adaptability. The final assembly reports included the status of assembly, the number of pieces assembled, the number of pieces stored, the assembly sequence, and the assembly time. Similarly, the development of the SCADA system allowed asset control as well as asset monitoring. The KPIs of the assembly process measured productivity (OTD) and time tracking (ATCT and TA) of the 16 tests, founding that the interconnection and digitization of the scale manufacturing cell were fully integrated and allowed repeatability; the proposed SF architecture represents an alternative for the small and medium automated factories to achieve interconnection and digitization, and it is ready to be tested in a more complex scenario.","2023","2025-05-05 17:09:20","2025-05-05 17:09:20","","101727-101749","","NA","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

During variable-parameter milling, particularly high-precision machining, machining parameters vary, and associated discrepancies in vibration signals are small. In this scenario, signal features that are extracted by hand or via deep learning methods cannot typically distinguish machining states via classification models. To solve this problem, a sequence labeling model developed using a stacked bidirectional long short-term memory network with a conditional random field layer (stacked-BiLSTM-CRF) is proposed in this study to automatically label and intercept vibration signals. The stacked BiLSTM receives the shallow features obtained by the short-time Fourier transform of the vibration signals and then outputs the extracted deep features to capture the before and after dependence of the signals. The stacked BiLSTM is then extended by stacking a CRF layer to explicitly model the dependence of signal labels. In a more accurate labeling scenario, the fast low-cost online semantic segmentation algorithm (FLOSS) is used to acquire more fine-grained signal boundary locations after obtaining the frame-level signal label using the stacked BiLSTM-CRF model. In addition, to evaluate model performance, a novel evaluation index for signal labeling is proposed. The feasibility and effectiveness of the proposed method are verified using the vibration signals collected from variable parameter cutting experiments, and results show that the proposed model achieves the best labeling performance of tested methods in nearly all scenarios.","2023-01","2025-05-05 17:09:21","2025-05-05 17:09:21","","NA","","NA","55","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The software semantic model introduced in this paper explores OSS through triple expressions in which the O4OSS properties are predicates. Findings This model improves the quality of web data by describing software in a structured machine-human readable profile, which is linked to the related data that was previously published on the web. Evaluating the OSS semantic model is accomplished through comparing it with previous approaches, comparing the software structured metadata with profile index of software in some well-known repositories, calculating the software retrieval rank and surveying domain experts. Originality/value Considering context-specific information and authority levels, the proposed software model would be applicable to any open and close software.

Trees that produce thousands of flowers at densities higher than that of herbs and produce much more nectar than the latter can be such keystone structures. However, there is a lack of specific information on trees, both native and alien, and their flower visitors in urban/suburban contexts, which blurs the conservation role that such species can perform. In 2019 and 2020, we thoroughly recorded the flower visitors to a silk-floss tree in suburban Guadalajara, Mexico. To our knowledge, this is the first comprehensive inventory of silk-floss tree flower visitors. We documented 79 species/morphospecies of insects; eight of birds, and one of mammals visiting the flowers. All, except two, are native to the region; three are endemic/quasi-endemic to Mexico. Besides direct and indirect floral resources, the silk-floss tree offered perches, resting/hiding cover, nesting substrate, and seed fibres used by several birds, and feeding substrate for gleaning insectivorous birds. Four species are on one or more conservation listings: monarch butterfly (endangered), pink-spotted swallowtail (vulnerable), sparkling-tailed hummingbird (threatened), and lesser long-nosed bat (near-threatened). Our data supports that small patches can enhance the quality of urban green spaces, and that rather than geographic origin, flower output drives visitation. Alien trees can be pollination enhancement `devices' for imperilled pollination networks. Silk-floss trees are a potential option for conservation-oriented urban greening, as well as to contribute to enhancing human enjoyment of nature, and provide opportunities for public outreach.","2023-12-31","2025-05-05 17:09:22","2025-05-05 17:09:22","","2028-2038","","45-48","57","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Direct measurements of turbulent fluxes are very challenging and sparse, and do not span the full range of environmental conditions that exist over the ocean. This means that empirical “bulk formulae” parameterizations that relate direct flux observations to concurrent measurements of the mean meteorological and sea surface variables contain considerable uncertainty. In this paper, we present a Python 3.6 (or higher) open-source software package “AirSeaFluxCode” for the computation of the heat (latent and sensible) and momentum fluxes. Ten different parameterizations are included, each based on published descriptions or code and each derived from a different set of observations, or different assumptions about the turbulent exchange processes. They represent a range of current expert opinion on how the fluxes depend on mean properties and can be used to explore uncertainty in calculated fluxes. AirSeaFluxCode also allows the adjustment of the mean meteorological input parameters (air temperature, humidity and wind speed) from the height at which they are obtained to a user-defined output height. This height adjustment enables the comparison of measurements, or model-derived values, made at different heights above sea-level. The parameterizations calculate the fluxes using input parameters that are relatively easily to measure, or are available as model output: wind speed, air temperature, sea surface temperature, atmospheric pressure and humidity. Where original code is available we have compared its output with that of AirSeaFluxCode. Any changes made to increase consistency across algorithms by standardizing computational methods or calculation of meteorological variables, for example, are discussed and the impacts quantified: these are shown to be insignificant except for a few cases where conditions were extreme, and AirSeaFluxCode is shown to be robust. We also investigate the impact on the fluxes caused by different assumptions about the exchange processes, or the choices inherent in the implementation of the parameterizations. For example, sea surface temperature usually refers to data typically obtained at depths of between 1 and 10 m. However, since some parameterizations require a “skin” sea surface temperature, code that adjusts temperature at depth to skin temperature is included: this has a very significant impact on the fluxes. Selecting a parameterization that is appropriate for the available sea surface temperature will avoid the need to adjust the sea temperature data and the uncertainties associated with that adjustment, and will also avoid the biases due to use of the “wrong” measure of temperature. Significant differences also resulted from assumptions about the size of reduction in sea surface humidity to account for salinity effects: the uncertainty in the reduction factor needs to be quantified in future analyses. Fluxes in extreme conditions are particularly uncertain since the transfer coefficients in the different parameterizations vary most at very high and very low wind speeds. Low wind speeds are also challenging for numerical implementation since choices have to be made regarding: convergence criteria for the iterative calculation, inclusion of a parameterization for convective gustiness, or application of ad hoc limits to various parameters. All of these choices can significantly affect the flux estimates for light winds.","2023-02-06","2025-05-05 17:09:23","2025-05-05 17:09:23","","NA","","NA","9","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

FOSS is subject to various legal terms and restrictions, depending on the type of open source license in force. Hence it is important to remain compliant with the FOSS license terms. Identifying the licenses that provide FOSS and understanding the terms of those licenses is not easy, especially when dealing with a large amount of reuse that is common in modern software development. Since reused software is often large, automated license analysis is needed to address these issues and support users in license compliant reuse of FOSS. However, existing license assessment tools can only identify the name and quantity of licenses embedded in software and thus cannot identify whether the licenses are being used safely and correctly. Moreover, they cannot provide a comprehensive analysis of the compatibility and potential risk that come with the term conflicts. In this paper, we propose DIKE, an automated tool that can perform license detection and conflict analysis for FOSS. First, DIKE extracts 12 terms under 3,256 unique open source licenses by manual analysis and Natural Language Processing (NLP) and constructs a license knowledge base containing the responsibilities of the terms. Second, DIKE scans all licenses from the code snippet for the input software and outputs the scan results in a tree structure. Third, the scan results match the license knowledge base to detect license conflicts from terms and conditions. DIKE designs two solutions for software with license conflicts: license replacement and code replacement. To demonstrate the effectiveness of DIKE, we first evaluate with the term extraction and responsibility classification, and the results show that their F1-scores reach 0.816 and 0.948, respectively. In addition, we conduct a measurement study of 16,341 popular projects from GitHub based on our proposed DIKE to explore the conflict of license usage in FOSS. The results show that 1,787 open source licenses are used in the project, and 27.2% of licenses conflict. Our new findings suggest that conflicts are prevalent in FOSS, warning the open source community about intellectual property risks.","2023","2025-05-05 17:09:24","2025-05-05 17:09:24","","495-505","","NA","NA","","","","International Conference on Software Engineering-Software Engineering in\n Practice Track","","","","","","NA","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISBN: 979-8-3503-0037-6 Place: NA Publisher: IEEE Press","","","","open source software; natural language processing; license analysis; license conflict; free","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We first identify the collaboration level of developers within the project files, such as the source, test, documentation, and build files, using the Author Cross Entropy (ACE). From the results we find out that test files report the highest degree of collaboration among the developers, perhaps because collaboration is critical to ensure convergence of functionality tests. Furthermore, the source code files show the least degree of collaboration, perhaps because of code ownership and the complexity and difficulty in code modification. Secondly, given the widespread usage of the Python programming language, we investigate the Python code tokens that are more prone to change and collaboration. Our findings offer insights into the specific project files and Python code tokens that developers typically collaborate on in the opensource community.

Like financial debt, it consists of the principal and an interest. Debt is usually paid back through code rewrites, refactoring, or the introduction of test code. When unchecked, interest can accumulate over time and lead to development crises where focus and resources must be shifted to resolve existing debt before the development process can be resumed. Existing software tooling allows practitioners to quantify the level of debt and identify its sources, allowing decision makers to measure and control it. We propose a detailed exploration of the characteristics of source code technical debt over the lifetime of several popular open-source applications. We employed a SonarQube instance configured for longitudinal analysis to study all publicly released versions of the target applications, amounting to over 15 years' worth of releases for each. We found that a small number of issue types were responsible for most of the debt and observed that refactoring reduced debt levels across most application packages. We observed increased variance in technical debt distribution and composition in early application versions, which lessened once applications matured. We addressed concerns regarding the accuracy of SonarQube estimations and illustrated some of its limitations. We aim to continue our research by including additional tools to characterize debt, leverage existing open data sets and extend our exploration to include additional applications and types of software.","2023","2025-05-05 17:09:25","2025-05-05 17:09:25","","292-314","","NA","1829","","","","Communications in Computer and Information Science","","","","","","NA","","","","","","","Backup Publisher: INSTICC ISBN: 978-3-031-36596-6; 978-3-031-36597-3 Place: NA Publisher: NA","","","","NA","","Kaindl, H.; Mannion, M.; Maciaszek, L.

Clients may struggle to select the best OSS-LMS package from a wide range of options, leading to a complex multi-criteria group decision -making (MCGDM) problem. This evaluates OSS-LMS packages based on several criteria like us-ability, functionality, e-learning standards, reliability, activity tracking, course development, assess-ment, backup and recovery, error reporting, efficiency, operating system compatibility, computer -managed instruction, authentication, authorization, troubleshooting, maintenance, upgrading, and scalability. Handling uncertain data is a vital aspect of OSS-LMS package evaluation. To tackle MCGDM issues, this study presents a consensus weighted sum product (c-WASPAS) method which is applied to an educational OSS-LMS package selection problem to evaluate four OSS-LMS pack-ages, namely ATutor, eFront, Moodle, and Sakai. The findings indicate that the priority order of alternatives is Moodle > Sakai > eFront > ATutor and, therefore, MOODLE is the best OSS-LMS package for the case study. A sensitivity analysis of criteria weights is also conducted, as well as a comparative study, to demonstrate the effectiveness of the proposed method. It is essential to note that proper OSS-LMS package evaluation is crucial to avoid negative impacts on organizational per-formance. By addressing MCGDM issues and dealing with uncertain information, the c-WASPAS method presented in this study can assist clients in selecting the most appropriate OSS-LMS pack-age from multiple alternatives. The findings of this study can benefit educational institutions and other organizations that rely on OSS-LMS packages to run their operations.","2023","2025-05-05 17:09:25","2025-05-05 17:09:25","","529-556","","3","34","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We introduce CODER, a novel graph-based CODE Recommendation framework for open source software developers, which accounts for the complex interactions among multiple parties within the system. CODER jointly models microscopic user-code interactions and macroscopic user-project interactions via a heterogeneous graph and further bridges the two levels of information through aggregation on file-structure graphs that reflect the project hierarchy. Moreover, to overcome the lack of reliable benchmarks, we construct three large-scale datasets to facilitate future research in this direction. Extensive experiments show that our CODER framework achieves superior performance under various experimental settings, including intra-project, cross-project, and cold-start recommendation.","2023","2025-05-05 17:09:29","2025-05-05 17:09:29","","1324–1333","","NA","NA","","","","WWW '23","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9781450394161 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software development; recommender system; Code recommendation; graph neural networks; multimodal recommendation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

If oral hygiene practice is poor, plaque easily accumulates on the tooth surface, especially in interproximal areas. To maintain a good oral environment, it is mandatory to remove or at least reduce the percentage of plaque formation from the oral cavity. To achieve this, interdental aids should be used along with toothbrushes, as cleansing the teeth only with a toothbrush is not effective. Various interdental aids, like interdental brushes, floss, toothpicks, etc., are now available on the market. The objective of the current survey was to rate knowledge as well as make a comparison between the cleaning effectiveness of interdental brushes and interdental floss to determine which was better at reducing plaque accumulation and, subsequently, dental caries. The survey was accessed by measuring individual plaque and gingival index before and after using interdental cleaning aids.Methodology The objective of the survey was to evaluate and analyze the efficiency of interdental brushes and interdental floss in maintaining oral hygiene among orthodontic patients residing in the Vidarbha region. After receiving approval from the Ethical Committee DMIHER(DU)/IEC/2023/721, a study was conducted over a 30-day period, focusing on a group of 100 individuals aged between 15 and 30 years, and their assessments were analyzed. The patient was briefed about the study and asked to make use of an interdental brush and interdental floss. The gingival index and plaque index were calculated on the same patients before and after the use of the interdental brush and interdental floss to determine which was better at reducing plaque accumulation on the surface of teeth. Descriptive analysis, unpaired for intergroup comparison, and paired T-tests for intragroup comparison were used. The software used was SPSS 24.0 (IBM Corp., Armonk, NY) and GraphPad Prism 7.0 (GraphPad Software, Inc., La Jolla, CA).Result Everyone's tooth surfaces naturally develop a thin layer of plaque biofilm, but the presence of heavy plaque deposits on teeth indicates poor dental hygiene, which can lead to various oral health issues. Failure to improve dental hygiene status can result in problems such as halitosis, gingival issues, periodontal disease, and eventually tooth loss. Dentists play a crucial role in raising awareness about these concerns among their patients and providing education on effective oral care practices, including the use of interdental aids in conjunction with toothbrushes. When comparing the effectiveness of interdental brushes and dental floss in removing plaque, interdental brushes have been found to be more efficient. They not only excel in plaque removal but also contribute to a reduction in gingival problems. The statistical analysis supports this, with a significant p-value of less than 0.01 for both the plaque index and gingival index when using interdental brushes, indicating their superior performance in maintaining oral health.Conclusion The study will help every individual improve their oral hygiene status with the help of an interdental aid and a toothbrush. This will reduce the chances of having gingival and periodontal diseases and eventually reduce the risk of tooth loss.","2023-09-29","2025-05-05 17:09:30","2025-05-05 17:09:30","","NA","","9","15","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, deciding a proper OSS to be adopted or to contribute to its development is a complex and error-prone task. Analyzing the OSS ecosystem (OSSECO) health may help providing information about: (1) the OSS itself (number of commits, days after the last release, etc.); and (2) their main actors (number of contributors, partners, etc.). There exist proposals that go further and provide aggregated high-level indicators (e.g. visibility as an aggregation of number of community events, number of partners, and other metrics). Nevertheless, there is a lack of useful OSSECO analysis tools to ease the decision making on which OSSECO has the health required by a potential OSS adopter or contributor. In this work, we provide OSS-CARE (OSSeCo heAlthy monitoR and analysEr), an OSS-independent, fully automatic, and real-time framework to assess OSSECO's health. OSS-CARE supports defining the ecosystem health objectives of potential OSS adopters, OSS contributors, and even OSS managers to inspect their provided health. These objectives are defined based on a well-established model characterizing health metrics that can be potentially aggregated by using a Bayesian network technique. Moreover, the integrated monitoring and analysis components perform an automated assessment of OSSECO's health by checking the fulfillment of the required health objectives. Furthermore, the result is shown in an appealing dashboard that may ease the complex decision making of which OSS to choose.","2023-07","2025-05-05 17:09:31","2025-05-05 17:09:31","","NA","","NA","22","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

Quantum Monte Carlo methods are a promising avenue of development as their core algorithm exhibits a number of favorable properties: it is highly parallel and scales favorably with the considered system size, with an accuracy that is limited only by the choice of the wave function Ansatz. The recently introduced machine-learned parametrizations of quantum Monte Carlo Ansatze rely on the efficiency of neural networks as universal function approximators to achieve state of the art accuracy on a variety of molecular systems. With interest in the field growing rapidly, there is a clear need for easy to use, modular, and extendable software libraries facilitating the development and adoption of this new class of methods. In this contribution, the DEEPQMC program package is introduced, in an attempt to provide a common framework for future investigations by unifying many of the currently available deep-learning quantum Monte Carlo architectures. Furthermore, the manuscript provides a brief introduction to the methodology of variational quantum Monte Carlo in real space, highlights some technical challenges of optimizing neural network wave functions, and presents example black-box applications of the program package. We thereby intend to make this novel field accessible to a broader class of practitioners from both the quantum chemistry and the machine learning communities.","2023-09-07","2025-05-05 17:09:32","2025-05-05 17:09:32","","NA","","9","159","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Hence, many models dealing with the calibration of ductile damage of materials have already been developed to predict failure initiation. Nevertheless, the challenge remains in obtaining an accurate representation of the fracture growth. Herein, an element deletion algorithm is developed and implemented into finite element open-source software. The deleted elements are replaced by new cells made of a virtual low-stiffness material. To better visualize the failure progression, the final model excludes these virtual cells from the representation. The functionality of the algorithm is tested through a series of two-dimensional simulations on three different geometries with a well-known behavior under uniaxial tension. Moreover, the failure response of a three-dimensional lattice structure is numerically investigated and compared against experimental data. The results of the two-dimensional simulations showed the capability of the algorithm to predict the onset of failure, crack nucleation, and fracture growth. Similarly, the onset and the initial fracture region were accurately captured in the three-dimensional case, with some convergence issues that prevent the visualization of the fracture growth. Overall, the results are encouraging, and the algorithm can be improved to introduce other computational functionalities.","2023-01","2025-05-05 17:09:33","2025-05-05 17:09:33","","NA","","1","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently, most analysis is performed either manually or with custom-made scripts, which makes analysis time-consuming and results difficult to compare across studies. To make quantitative GUV analysis accessible and fast, we present DisGUVery, an open-source, versatile software that encapsulates multiple algorithms for automated detection and analysis of GUVs in microscopy images. With a performance analysis, we demonstrate that DisGUVery's three vesicle detection modules successfully identify GUVs in images obtained with a wide range of imaging sources, in various typical GUV experiments. Multiple predefined analysis modules allow the user to extract properties such as membrane fluorescence, veside shape, and internal fluorescence from large populations. A new membrane segmentation algorithm facilitates spatial fluorescence analysis of nonspherical vesicles.

Two amendments are proposed. First, we add a new dimension to the framework, institutional competence (“where to own”), which denotes that individuals and firms have heterogeneous abilities to assess how an institutional environment affects the potential uses of a resource. Second, we argue that institutional uncertainty moderates the three original dimensions of the framework, impairing the exercise of ownership competence of some entrepreneurs and firms more than of others. We use examples from the literature to illustrate our arguments. We also discuss the implications of our analysis.Managerial SummaryThe ownership competence framework is built on the idea that business owners have different abilities to deploy resources and create value. Starting from this contribution, we shed light on the specific role that the institutional environment plays in the exercise of ownership competence. We argue that the ownership competence framework must explicitly consider where ownership takes place in order to explain the actions of entrepreneurs and firms. We also claim that institutional uncertainty can influence value creation in more subtle ways than indicated in the original formulation of the ownership competence framework.

Structural diagrams of different configurations are given, functional purpose and capabilities of each level of simulators are shown. The initial level allows independent assemble the simulator from publicly available elements (laptop, webcam, weapon layouts, IR LEDs), which can contribute to widespread use both in schools and at home, but is low in accuracy and manufacturabili (requires daily calibration). The basic level also allows independent assemble the simulator, and less publicly available elements (laptop, projector, mockup weapons, laser emitters, FHD camera), which allows to be used both in schools and in DOSAAF structures, and has acceptable accuracy and manufacturability (a weekly calibration is enough, but assembling a mock-up weapon with laser emitters requires adjustments). It is recommended to limit the special level to virtual reality simulators, including a helmet with a smartphone and a mockup of a weapon with its smartphone which also contributes to its public availability and widespread use. The simulator software algorithm should fully support all implementation levels with different configurations and include a multimedia shooting training system. Mathematical models of external ballistics of thrown equipment for Kalashnikov assault rifle, Makarov pistol, hand-held anti-tank grenade launcher 7 products are described in detail, taking into account changes in atmospheric factors (temperature, air pressure, wind force) and dispersion of various types of ammunition. The above review of rifle simulators and their experience revealed the main trends of improvement - use of virtual reality and training not only direct shooting skills, but also training in the eligibility of the use of weapons, safe handling of them and even tactical interaction in the group.","2023","2025-05-05 17:09:37","2025-05-05 17:09:37","","251-267","","4","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Forty healthy patients who met the necessary eligibility criteria were allocated by block randomization to either the test group (20 patients) or control group (20 patients). Cone beam computed tomography scans were obtained at enrolment (T0), immediately after surgery (T1), at delivery of the prosthetic rehabilitation (T2), and 1 year after functional implant loading (T3). Mean differences were expressed with the 95% confidence interval; significance was set at P < 0.05. ESBG was significantly increased with Bio-Oss Collagen compared with no grafting material at T1, T2, and T3 (P < 0.001). A gradual decrease in ESBG was observed over time with both treatment modalities (P < 0.001), which diminished the difference between the test and control groups at T2 and T3. ESBG was observed to be positively correlated with implant protrusion length and negatively correlated with the residual bone height. In osteotome-mediated sinus floor elevation, the application of Bio-Oss Collagen underneath the elevated Schneiderian membrane improved ESBG significantly when compared with no grafting material. However, the increased ESBG seems not to have positively improved the treatment outcomes in terms of the implant stability quotient or the survival of the implants or suprastructures.","2023-11","2025-05-05 17:09:37","2025-05-05 17:09:37","","1205-1215","","11","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: JOURNAL PRODUCTION DEPT, ROBERT STEVENSON HOUSE, 1-3 BAXTERS PLACE,\n LEITH WALK, EDINBURGH EH1 3AF, MIDLOTHIAN, SCOTLAND Publisher: CHURCHILL LIVINGSTONE","","","","Cone-beam computed tomography; Alveolar ridge augmentation; Maxilla; Randomized controlled trial; Radiography; Dental\n implants; Sinus floor\n augmentation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59%) patches, out of which 587 (32.34%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18%.","2023","2025-05-05 17:09:38","2025-05-05 17:09:38","","2366-2380","","NA","NA","","","","CCS '23","","","","","","English","","","","","","","Backup Publisher: Assoc Comp Machinery; ACM SIGSAC; Huawei; Natl Sci Fdn; Technol Innovat\n Inst; Twenty Second Century Dora Technol; Ant Res; IBM; TikTok; Abelian;\n Input Outut ISBN: 979-8-4007-0050-7 Place: 1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES Publisher: ASSOC COMPUTING MACHINERY","","","","Patch backporting; Patch Semantics; Patch type","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This study presents an overview of the properties of milkweed floss and its potential use in reinforced-polymer composites. Milkweed flosses from Quebec were analyzed to determine their overall dimensions, density, porosity, coefficient of acoustic absorption, thermal conductivity, thermal resistance, and elastic modulus. In parallel, a portion of milkweed fibers was treated with acetone to modify their surface, and the properties of the treated fibers were measured and compared against the characteristics of the original fibers. Infrared spectroscopy was employed to assess differences between the chemical groups on the surface of treated and native fibers. The treatment with acetone removed fatty acids, waxes, and free sugars from the fibers' surface. The acetone treatment did not affect the fibers' microstructure nor their acoustic absorption capacity. The acetone-treated fibers showed greater thermal resistance and a higher thermal conductivity than native milkweed floss. The elastic modulus of milkweed decreased by nearly 49% after the acetone treatment.","2023-04-24","2025-05-05 17:09:39","2025-05-05 17:09:39","","NA","","1","20","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA Publisher: TAYLOR & FRANCIS INC","","","","fiber microstructure; Natural hollow fibers; reinforcing fiber; thermal properties; thermo-acoustic insulation; \n mechanical properties","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Computational intelligence (CI) in general and particle swarm optimization (PSO) algorithms in particular have been shown to accelerate finding optimal printing parameters. Unfortunately, the implementation of CI has been prohibitively complex for noncomputer scientists. To overcome these limitations, this article develops, tests, and validates PSO Experimenter, an easy-to-use open-source platform based around the PSO algorithm and applies it to optimizing recycled materials. Specifically, PSO Experimenter is used to find optimal printing parameters for a relatively unexplored potential distributed recycling and additive manufacturing (DRAM) material that is widely available: low-density polyethylene (LDPE). LDPE has been used to make filament, but in this study for the first time it was used in the open source fused particle fabrication/fused granular fabrication system. PSO Experimenter successfully identified functional printing parameters for this challenging-to-print waste plastic. The results indicate that PSO Experimenter can provide 97% reduction in research time for 3D printing parameter optimization. It is concluded that the PSO Experimenter is a user-friendly and effective free software for finding ideal parameters for the burgeoning challenge of DRAM as well as a wide range of other fields and processes.","2023-12-01","2025-05-05 17:09:41","2025-05-05 17:09:41","","1287-1300","","6","10","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 140 HUGUENOT STREET, 3RD FL, NEW ROCHELLE, NY 10801 USA Publisher: MARY ANN LIEBERT, INC","","","","LDPE; particle swarm optimization; recycling; waste plastic; fused\n particle fabrication","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Key examples of this include identification of ripening stages of fruit such as tomatoes and the determination of chlorophyll content as an indicator of plant health. While methods exist for determining these important phenotypes, they often require proprietary software or require coding knowledge to adapt existing code.ResultsWe provide a set of free and open-source Python scripts that, without any adaptation, are able to perform background correction and colour correction on images using a ColourChecker chart. Further scripts identify objects, use an object of known size to calibrate for size, and extract the average colour of objects in RGB, Lab, and YUV colour spaces. We use two examples to demonstrate the use of these scripts. We show the consistency of these scripts by imaging in four different lighting conditions, and then we use two examples to show how the scripts can be used. In the first example, we estimate the lycopene content in tomatoes (Solanum lycopersicum) var. Tiny Tim using fruit images and an exponential model to predict lycopene content. We demonstrate that three different cameras (a DSLR camera and two separate mobile phones) are all able to model lycopene content.

In the second example, we estimate the chlorophyll content of basil (Ocimum basilicum) using leaf images and an exponential model to predict chlorophyll content.ConclusionA fast, cheap, non-destructive, and inexpensive method is provided for the determination of the size and colour of plant materials using a rig consisting of a lightbox, camera, and colour checker card and using free and open-source scripts that run in Python 3.8.

Recent research has linked these problems to the values of Lyapunov exponents for the forward-dynamics, which describe the growth or shrinkage of infinitesimal perturbations. Here, we propose gradient flossing, a novel approach to tackling gradient instability by pushing Lyapunov exponents of the forward dynamics toward zero during learning. We achieve this by regularizing Lyapunov exponents through backpropagation using differentiable linear algebra. This enables us to ""floss"" the gradients, stabilizing them and thus improving network training. We demonstrate that gradient flossing controls not only the gradient norm but also the condition number of the long-term Jacobian, facilitating multidimensional error feedback propagation. We find that applying gradient flossing prior to training enhances both the success rate and convergence speed for tasks involving long time horizons. For challenging tasks, we show that gradient flossing during training can further increase the time horizon that can be bridged by backpropagation through time. Moreover, we demonstrate the effectiveness of our approach on various RNN architectures and tasks of variable temporal complexity. Additionally, we provide a simple implementation of our gradient flossing algorithm that can be used in practice. Our results indicate that gradient flossing via regularizing Lyapunov exponents can significantly enhance the effectiveness of RNN training and mitigate the exploding and vanishing gradients problem.","2023","2025-05-05 17:09:43","2025-05-05 17:09:43","","NA","","NA","NA","","","","NIPS '23","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: Red Hook, NY, USA Publisher: Curran Associates Inc.","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers' positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.","2023-07","2025-05-05 17:09:43","2025-05-05 17:09:43","","NA","","4","32","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY","","","","hierarchy; developer networks; Open-source software projects; organizational\n structure","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We start with the construction of 6 categories of leadership behaviors based on existing leadership studies. Then, we manually label leadership behaviors in 10,000 issue comments from 10 OSS projects, and extract 304 heuristic linguistic patterns which represent different types of emergent leadership behaviors in flexible and concise manners.

When packages are large, they often carry maintainability quality issues. In the literature, there is a lack of empirical evidence on the specific maintainability issues that occur when packages become too large. Our study fills this gap by performing relationship analysis of package size with respect to internal maintainability characteristics (coupling, cohesion, and complexity) using package-level metrics collected from 111 open-source Java projects provided in Qualitas Corpus. Our results show significantly higher main-tainability issues in large packages as indicated by the maintainability metrics. We also report strong relationships of package size with cohesion (represented by the number of connected components in a package) and complexity (measured by the number of internal relationships in a package). Based on these strong associations with package size, we show that these cohesion and complexity metrics can be used to identify large package refactoring opportunities. Furthermore, we also discuss why some maintainability metrics (e.g., coupling metrics) may not be useful for refactoring large packages.Editor's note: Open Science material was validated by the Journal of Systems and Software Open Science Board.(c) 2023 Elsevier Inc.

Nowadays, pork floss is known to consumers as a leisure food. It is made from pork through a unique process in which the muscle fibers become flaky or granular and tangled. In this study, a deep learning-based approach is proposed to detect the quality characteristics of pork floss structure. Describe that the experiments were conducted using widely recognized brands of pork floss available in the grocery market, omitting the use of abbreviations. A total of 8000 images of eight commercially available pork flosses were collected and processed using sharpening, image gray coloring, real-time shading correction, and binarization. After the machine learning model learned the features of the pork floss, the images were labeled using a manual mask. The coupling of residual enhancement mask and region-based convolutional neural network (CRE-MRCNN) based deep learning framework was used to segment the images. The results showed that CRE-MRCNN could be used to identify the knot features and pore features of different brands of pork floss to evaluate their quality. The combined results of the models based on the sensory tests and machine vision showed that the pork floss from TC was the best, followed by YJJ, DD and HQ. This also shows the potential of machine vision to help people recognize the quality characteristics of pork floss structure.","2023","2025-05-05 17:09:44","2025-05-05 17:09:44","","NA","","NA","7","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We aimed to compare the impact of early palliative care including formal concertation with oncologists on decision for an additional line of chemotherapy compared with usual oncology care. Methods This randomized prospective study enrolled adult women with metastatic breast cancer and visceral metastases with a 3rd- or 4th-line chemotherapy (CT). Patients received usual oncology care with a palliative care consultation only upon patient or oncologist request (standard group, S) or were referred to systematic palliative care consultation including a regular concertation between palliative care team and oncologists (early palliative care group, EPC). The primary endpoint was the rate of an additional CT (4th or 5th line) decision. Quality of life, symptoms, social support and satisfaction were self-evaluated at 6 and 12 months, at treatment discontinuation or 3 months after discontinuation. Results From January 2009 to November 2012, two authorized cancer centers included 98 women (EPC: 50; S: 48). Thirty-seven (77.1%, 95%CI 62.7-88%) patients in the EPC group had a subsequent chemotherapy prescribed and 36 (72.0%, 95%CI 57.5-83.8%) in the S group (p = 0.646). No differences in symptom control and global quality of life were observed, but less deterioration in physical functioning was reported in EPC (EPC: 0 [- 53-40]; S: - 6; 7 [- 60 to - 20]; p = 0.027). Information exchange and communication were significant improved in EPC (exchange, EPC: - 8.3 [- 30 to + 7]; S: 0.0 [- 17 to + 23]; p = 0.024; communication, EPC: 12.5 [- 8 to - 37]; S: 0.0 [- 21 to + 17]; p = 0.004). Conclusion EPC in metastatic breast cancer patients did not impact the prescription rate of additional chemotherapy in patients a 3rd- or 4th-line chemotherapy for metastatic breast cancer; however, EPC may contribute to alleviate deterioration in physical functioning, while facilitating communication.","2023-01","2025-05-05 17:09:44","2025-05-05 17:09:44","","NA","","1","31","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER","","","","Advanced breast cancer; Chemotherapy; Supportive care; Early palliative\n care","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A prime example for this phenomenon is open source software (OSS) development, where multiple actors contribute to a public good, which is also integrated into company-owned software products. Despite the importance of aligning community work on the public good with own in-house development efforts, firms have limited options to directly control the OSS project or the project's outcome. This research reflects on resource deployment control, a control mode in which firms assign own developers to work for an OSS project to influence the OSS project, and tests hypotheses on individual developer levels. Design/methodology/approach This research tests the effect of perceived resource deployment control on opinion leadership by analyzing employed Linux kernel developers. Findings The findings show that developers who perceive being assigned to an OSS project to enact control also exhibit opinion leadership. This research also investigates boundary conditions such as the OSS business model a firm operates and the reputation developers assign to the developers' employer.

Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when “simple stupid bugs” were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub. Leveraging a statistical survival model and other non-parametric statistical tests, we found that there were two main categories of categorical variables that affect a bug's life; Time Factors and Author Factors. We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time. These findings will provide vital insight to help the open-source community mitigate the abundance of code and can be used in future research to aid in bug-finding programs.","2023-03","2025-05-05 17:09:44","2025-05-05 17:09:44","","NA","","5","13","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","survival analysis; bug fixes; one-line bugs; statistical analysis","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Despite being problematic, fixing license incompatibility issues requires substantial efforts due to the lack of license understanding and complex package dependency. In this paper, we propose LiResolver, a fine-grained, scalable, and flexible tool to resolve license incompatibility issues for open source software.

Firstly, a heterogeneous information network is constructed based on meta-paths. Secondly, the Canopy algorithm is used to obtain the number of initial communities. Thirdly, the skip-gram model is used to identify seed nodes for community detection. Finally, METHODS detects heterogeneous communities around the seed nodes.

Standardization in OSS quality is of vital importance as a communication vehicle for stakeholders in identifying and selecting high-quality products. Thus, meta-models help to define a standardized language and enable to propose quality models that can be used to perform comparable measurements.Objective Considering the lack of a comprehensive meta-model of OSS quality in the literature, there appears a need to see a more complete picture of OSS quality and to represent its concepts more formally. Therefore, in this study, it is aimed to develop a solid base for a comprehensive meta-model of OSS quality to create a common understanding among stakeholders.Method A systematic way has been followed toward developing a common structure, defining a consistent terminology and, finally, providing a meta-model of OSS quality. In this context, (1) the common structure of the quality models for OSS has been investigated, (2) the terms of the general-purpose meta-models of software quality have been analyzed based on the international standards, and (3) the terms of the quality models for OSS have been mapped with the elements of these meta-models.Results An initial meta-model of OSS quality, which employs a unified structure from the OSS quality models and eliminates the inconsistencies determined in the general-purpose meta-models of software quality, has been proposed and an implementation of this meta-model has been demonstrated.Conclusion This initial meta-model of OSS quality with a standard terminology can be taken as a guide by researchers who will propose or revise their OSS quality models. It will allow developing multiple OSS quality models with homogenous structure and terms, and also enable comparing the evaluation results obtained by these models.","2023-09","2025-05-05 17:09:45","2025-05-05 17:09:45","","721-773","","3","31","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; OSS; Software; Open-source software; Context; Software quality; Terminology; Standardization; Meta-model; Metamodeling; Quality evaluation; Quality measurement; Quality metrics; Quality model; Quality standards; Computers–Software","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

EBA involves the use of psychometric instruments to gather data that can inform clinical decision-making, inform policymakers, and serve as a basis for research and quality management. Despite its potential, EBA is often hindered by barriers such as workload and cost, leading to its underutilization. Regarding low- and middle-income countries (LMIC), the implementation of EBA is recognized as a key strategy to address and close the prevalent mental health treatment gap.To simplify the application of EBA including in LMIC, an international team of researchers and practitioners from Tanzania, Kosovo, Chile, and Switzerland developed the Mental Health Information Reporting Assistant (MHIRA). MHIRA is an open-source electronic health record that streamlines EBA by digitising psychometric instruments and organising patient data in a user-friendly manner. It provides immediate and convenient reports to inform clinical decision-making.The current article provides a comprehensive overview of the features and technical details of MHIRA, as well as insights from four implementation scenarios. The experience gained during the implementations as well as the user-feedback suggests that MHIRA has the potential to be successfully implemented in a variety of clinical contexts and simplify the use of EBA. However, further research is necessary to establish its potential to sustainably transform healthcare services and impact patient outcomes.In conclusion, MHIRA represents an important step in promoting the widespread adoption of EBA in mental health. It offers a promising solution to the barriers that have limited the use of EBA in the past and holds the potential to improve patient outcomes and support the ongoing efforts to address gaps in mental health care.","2023-10-02","2025-05-05 17:09:46","2025-05-05 17:09:46","","NA","","1","23","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON N1 9XW, ENGLAND Publisher: BMC","","","","Software; Open-source; Electronic health record; Evidence-based assessment; Implementation sciences; Mental health; \n Digital; Low- and\n middle-income countries","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

SU2 is one of these open -source tools. Unlike other open -source alternatives, SU2 is equipped with boundary condition types, solvers and methods that are especially developed for the analysis and design of turbomachinery. The aim of this work is to explore and investigate the capabilities of SU2 in the prediction of performance parameters of radial compressors. Two different single stage shrouded compressor geometries, one with a vaneless diffuser and the other with a vaned diffuser have been investigated with steady state CFD. The compressors were designed by MAN Energy Solutions Schweiz AG. Computational results with SU2 showed a satisfactory agreement with both the experimental data and reference CFD solutions obtained with Fidelity Flow, which is formerly known as Numeca Fine TURBO. Only at the relatively higher mass flow rates the difference between references and SU2 were higher compared to other operating points. After performance parameters were successfully calculated with SU2, the optimization tools that come with SU2 were also used. A 2D adjoint optimization study on the vane of the vaned diffuser was carried out. The study was carried out at a single operating point that is close to choke conditions. The loss generated by the large separated flow region at the suction side of the diffuser vane was reduced by 0.55 % in the optimized geometry using minimal modifications on the existing vane geometry to keep the performance of the compressor intact at other operating points. However, the resulting modification increased the total pressure loss by 0.86 % at one of the design operating points. This performance penalty could be due to the discontinuity in the vane geometry generated by the optimizer. Overall, the study shows that SU2 has the basic numerical schemes and models that are required for the analysis of radial turbomachinery flows and geometry optimization.","2023","2025-05-05 17:09:46","2025-05-05 17:09:46","","233-242","","2","43","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: TIBTD MAKINA MUHENDISLIGI BOLUMU ODTU, ANKARA, 06531, Turkiye Publisher: TURKISH SOC THERMAL SCIENCES TECHNOLOGY","","","","Optimization; Open-source; Computational Fluid Dynamics; SU2; Turbomachinery; \n Compressor","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Most large and complex software packages partitioned across multiple portals and involve many users - each with their role in the software package; those users have different perspectives on the software package, defined by their knowledge, responsibilities, and commitments. Thus, a multi-perspective approach has been used in usability evaluation to overcome the challenge of inconsistency between users' perspectives; the inconsistency challenge would lead to an ill-advised decision on the selection of a suitable OSS. This study aimed to assist the public and private organizations in evaluating and selecting the most suitable OSS. The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.","2023-01","2025-05-05 17:09:46","2025-05-05 17:09:46","","187-277","","01","22","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 5 TOH TUCK LINK, SINGAPORE 596224, SINGAPORE Publisher: WORLD SCIENTIFIC PUBL CO PTE LTD","","","","evaluation; selection; open-source software (OSS); benchmarking; BWM; decision matrix; Multi-criteria decision making (MCDM); \n VIKOR","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals' early career stages profoundly impact their long-term career success. However, newcomers' early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers' dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers' contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers' early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers' technical success. We discussed the implications and summarized practical recommendations to OSS newcomers.

Yet, newcomers face a steep learning curve during OSS onboarding in which they must overcome a multitude of technical, social, and knowledge barriers. To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., “good first issues”), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.","2023","2025-05-05 17:09:46","2025-05-05 17:09:46","","324-336","","NA","NA","","","","International Conference on Software Engineering-Software Engineering\n Education and Training","","","","","","English","","","","","","","Backup Publisher: IEEE; Assoc Comp Machinery; IEEE Comp Soc ISBN: 979-8-3503-2259-0 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","open source software; open source onboarding; software engineering\n education","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These experiments are executed by training the model under observation with varying configurations. Since executing a typical training run can take days even on proven acceleration fabrics such as Graphics Processing Units (GPU), properly managing training data, avoiding human error in configuration preparations and securing the repeatability of the experiments are of utmost importance. In this paper, we present two open source software tools that aim to achieve these goals, namely, a Dataset Manager (DatumAid) tool and a Training Automation Manager (OrchesTrain) tool. DatumAid is a software tool that integrates with Computer Vision Annotation Tool (CVAT) to facilitate the management of annotated datasets. By adding additional functionality, DatumAid allows users to filter labeled data, manipulate datasets, and export datasets for training purposes. The tool adopts a simple code structure while providing flexibility to users through configuration files. OrchesTrain aims to automate model training process by facilitating rapid preparation and training of models in the desired style for the intended tasks. Users can seamlessly integrate their models prepared in the PyTorch library into the system and leverage the full capabilities of OrchesTrain. It enables the simultaneous or separate usage of Wandb, MLflow, and TensorBoard loggers. To ensure reproducibility of the conducted experiments, all configurations and codes are saved to the selected logger in an appropriate structure within a YAML file along with the serialized model files.

This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software. Design/methodology/approach A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76%. Findings The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff. Research limitations/implications This study is geographically limited to the university libraries in Islamabad. Practical implications This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries. Originality/value This study concludes that the development of IRs in university libraries is a need of the hour. Although the launching of IRs requires certain skills and competencies, Pakistani librarians can overcome these challenges by mastering the ICT skills.","2023-01-06","2025-05-05 17:09:47","2025-05-05 17:09:47","","47-55","","1","51","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Library And Information Sciences; Open source; Open-source software; Dissertations & theses; Digital libraries; Digital preservation; Academic libraries; Digital library; Digital library system; Free softwares; Institutional repositories; Institutional repository; Islamabad Pakistan; Librarians’ challenges; Librarians’ perceptions; Library; Library science; Pakistan; Repository; 51921:Libraries; Archives","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In revision hip arthroplasty (RHA), establishing the center of rotation (COR) can be technically challenging due to the acetabular bone destruction that is usually present, particularly in severe cases such as Paprosky type II and III defects. The aim of this study was to demonstrate the use of open-source medical image reconstruction software and low-cost 3D anatomical models in pre-surgical planning of RHA. Methods. A total of 10 patients, underwent RHA and were included in the study. Computed tomography (CT) scans were performed for all cases, before surgery and approximately 1 week after the procedure. The reconstruction of CT data, 3D virtual planning of the COR and positioning of acetabular cups, including their inclination and anteversion angles, was carried out using the free open source software platform 3D Slicer. In addition, anatomical models of the pelvis were built on a desktop 3D printer from polylactic acid (PLA). Preoperative and postoperative reconstructed imaging data were compared for each patient, and the position of the acetabular cups as well as the COR were evaluated for each case. Results. Analysis of the pre- and post-op center of rotation position data indicated statistically insignificant differences for the location of the COR on the X-axis (1.5 mm, t = 0.5741, p = 0.5868) with a fairly strong correlation of the results (r = -0.672, p = 0.0982), whilst for the location of the COR in the Y and Z-axes, there was statistical dependence (Y axis, 4.7 mm, t = 3.168 and p = 0.0194; Z axis, 1.9 mm, t = 1.887 and p = 0.1081). A strong correlation for both axes was also observed (Y and Z) (Y-axis, r = 0.9438 and p = 0.0014; Z-axis, r = 0.8829 and p = 0.0084). Analysis of inclination angle values showed a statistically insignificant difference between mean values (3.9 degrees, t = 1.111, p = 0.3092) and a moderate correlation was found between mean values (r = -0.4042, p = 0.3685). Analysis of the anteversion angle showed a statistically insignificant difference between mean values (1.9 degrees, t = 0.8671, p = 0.4192), while a moderate correlation between mean values was found (r = -0.4782, p = 0.2777). Conclusions. Three-dimensional reconstruction software, together with low-cost anatomical models, are very effective tools for pre-surgical planning, which have great potential use in orthopedic surgery, particularly RHA. In up and in- and up and out-type defects, it is essential to establish a new COR and to identify three support points within the revision acetabulum in order to correctly position acetabular cups.","2023-08","2025-05-05 17:09:47","2025-05-05 17:09:47","","NA","","15","13","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Forty healthy patients (27 female, 13 male) with a mean age of 49 years (range 24-74 years) were randomly allocated to the test or control group. Outcome measures included survival of the suprastructures and implants, periimplant marginal bone loss, complications, and PROMs; the latter included the Oral Health Impact Profile-14 and a self-administered questionnaire with visual analogue scales to assess the peri-implant tissue, implant crown, function of the implant, total implant treatment outcome, and oral health-related quality of life. Mean differences were expressed with the standard deviation and 95% confidence interval. The level of significance was 0.05. Survival of the suprastructures and implants was 100% with both treatment modalities. No significant difference in any of the outcome measures was observed between the test and control groups. High patient satisfaction and a significant improvement in quality of life were observed with both treatment modalities. Consequently, no significant difference in implant treatment outcome between the test and control groups was revealed after 1 year of implant loading. Neither of the treatment modalities can therefore be considered better than the other.","2023-09","2025-05-05 17:09:47","2025-05-05 17:09:47","","988-997","","9","52","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: JOURNAL PRODUCTION DEPT, ROBERT STEVENSON HOUSE, 1-3 BAXTERS PLACE,\n LEITH WALK, EDINBURGH EH1 3AF, MIDLOTHIAN, SCOTLAND Publisher: CHURCHILL LIVINGSTONE","","","","Quality of life; Alveolar ridge augmentation; Dental implants; Health care surveys; Randomized controlled trial; \n Maxilla; Sinus floor\n augmentation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In such platforms, developers have to collaborate and deal with issues of collaboration in open-source software development. Although collaboration is challenging, collaborative development produces better software systems than any developer could produce alone. Several approaches have investigated collaboration challenges, for instance, by proposing or evaluating models and tools to support collaborative work. Despite the undeniable importance of the existing efforts in this direction, there are few works on collaboration from perspectives of developers. In this work, we aim to investigate the perceptions of open-source software developers on collaborations, such as motivations, techniques, and tools to support global, productive, and collaborative development. Following an ad hoc literature review, an exploratory interview study with 12 open-source software developers from GitHub, our novel approach for this problem also relies on an extensive survey with 121 developers to confirm or refute the interview results. We found different collaborative contributions, such as managing change requests. Besides, we observed that most collaborators prefer to collaborate with the core team instead of their peers. We also found that most collaboration happens in software development (60%) and maintenance (47%) tasks. Furthermore, despite personal preferences to work independently, developers still consider collaborating with others in specific task categories, for instance, software development. Finally, developers also expressed the importance of the social coding platforms, such as GitHub, to support maintainers, and contributors in making decisions and developing tasks of the projects. Therefore, these findings may help project leaders optimize the collaborations among developers and reduce entry barriers. Moreover, these findings may support the project collaborators in understanding the collaboration process and engaging others in the project.","2023-05","2025-05-05 17:09:47","2025-05-05 17:09:47","","NA","","5, SI","35","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","distributed collaboration; collaboration in software development; open-source software projects; \n sustained developer community participation; collaborative software\n development","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

At 300 mu g/mL concentration, the SFSB extract exhibited the highest inhibition percentages of 83.33 and 86.67 for R. solani and F. oxysporum, respectively. In addition to its antimicrobial activity, SFSB extract exhibited strong antioxidant activity (IC50 value of 140.88 g/mL). HPLC analysis of the extract revealed the presence of various phenolic acids and flavonoids.

The absence of comprehensive security assessment as well as a consolidated and ubiquitous roadmap for vulnerability patching and security hardening, makes open-source solution a risk for widespread enterprise use. This paper introduces a security assurance approach which addresses open-source hardware and software shortcoming in an end-to-end manner, by providing a logical decomposition of any such module into four distinct component layers: device, network, application and cognitive. This allows highly focused security assessment, taking into consideration the specific characteristics of each layer. In addition, the paper provides an approach on how open-source solution security can be improved, through decomposition, layered vulnerability mitigation and specialized security hardening techniques.

State-of-the-art characterization of sample materials related to these fields, deploying high-end instrumentation, allows for gathering large quantities of molecular composition data. One established technological platform is ultrahigh-resolution mass spectrometry, e.g., Fourier-transform mass spectrometry (FT-MS). However, the huge amounts of data acquired in FT-MS often result in tedious data treatment and visualization. FT-MS analysis of complex matrices can easily lead to single mass spectra with more than 10,000 attributed unique molecular formulas. Sophisticated software solutions to conduct these treatment and visualization attempts from commercial and noncommercial origins exist. However, existing applications have distinct drawbacks, such as focusing on only one type of graphic representation, being unable to handle large data sets, or not being publicly available. In this respect, we developed a software, within the international complex matrices molecular characterization joint lab (IC2MC), named “python tools for complex matrices molecular characterization” (PyC2MC). This piece of software will be open-source and free to use. PyC2MC is written under python 3.9.7 and relies on well-known libraries such as pandas, NumPy, or SciPy.

The transformation of the measured reflection coefficient to complex permittivity is performed based on three different methods. The software library contains the dielectric spectra of common reference liquids, which can be used to transform the reflection coefficient into the dielectric spectra. Several Python routines that are commonly employed (e.g., SciPy and NumPy) in the field of science and engineering are required only so that the users can alter the software structure depending on their needs. The modeling algorithm exploits the Markov Chain Monte Carlo method for the data regression. The discrete relaxation models can be built by a proper combination of well-known relaxation models. In addition to these models, electrode polarization, a typical measurement artifact for interpreting dielectric spectra, can be incorporated into the modeling algorithm. A continuous relaxation model, which solves the Fredholm integral equation of the first kind (a mathematically ill-posed problem), is also included. This open-source software enables users to freely adjust the physical parameters to obtain physical insight into their materials under test and will be consistently updated for more accurate measurement and interpretation of dielectric spectra in an automated manner. This work describes the theoretical and mathematical background of the software, lays out the workflow, and validates the software functionality based on both synthetic and empirical data included in the software.

Solution method: The reflection coefficient data is obtained as a text format from a Vector Network Analyzer (VNA). This text data is parsed into a Numpy array. Three different modules (Stuchly, Marsland, and Komarov) can be used to transform the parsed reflection coefficient data into complex permittivity as a function of the measurement frequency. The resultant dielectric spectra can be dissected and interpreted by fitting either discrete relaxation model(s) based on the Markov Chain Monte Carlo algorithm or a continuous relaxation model by applying the Zasetsky-Buchner method.

Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.","2023-03","2025-05-05 17:09:48","2025-05-05 17:09:48","","361-390","","1","47","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: UNIV MINNESOTA-SCH MANAGEMENT 271 19TH AVE SOUTH, MINNEAPOLIS, MN 55455\n USA Publisher: SOC INFORM MANAGE-MIS RES CENT","","","","pandemic; unemployment; open source software; Open source software community; IT knowledge workers; IT professionals; \n digital resilience; \n exogenous shock","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Considering that traditional salinity reconstruction methods often suffer from various factors such as additional constraints, priori physical assumptions and large of specific regression coefficients, a generative adversarial networks (GANs) based deep learning (DL) framework is proposed to directly construct a near real-time, high-resolution daily three-dimensional ocean subsurface salinity (3D OSS) dataset from a data driven perspective in this study. Four models with different structural combinations are designed in the China's marginal seas. Experimental results demonstrate that the models can successfully reconstruct the high-precision and high-resolution 3D OSS on a daily scale in 12 depth levels (from 2 m to 200 m). The asymmetric inception3DGAN model with all enhanced structures has the highest accuracy, the average root-mean-squared error (RMSE) is 0.135psu, the average coefficient of determination (R2) is 0.5641 and the percent bias is 0.436%. Comparing with model without enhanced structures, the average RMSE is decreased by 22.41% when adding all the enhancement structures. Besides, temporal and spatial error analysis are also conducted to evaluate the models' performance from different aspects. Finally, the model results are used to analyze common ocean elements, such as water mass properties, dynamic fields and geostrophic velocity fields, demonstrating that the 3D OSS dataset construction approach proposed in this study not only provides some new insights into ocean observations, but also has high application values.","2023-08","2025-05-05 17:09:48","2025-05-05 17:09:48","","NA","","NA","184","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD","","","","Deep learning; Data-driven; Ocean subsurface salinity; T-S mapping; Generative\n adversarial networks","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In their article, the authors make a strong case that “reset thinking” geared towards a more “sustainable” redesign of the global economy promotes extensive state interventionism and cronyism capitalism, and therefore reject the idea of a need for “a funda-mental rethink of existing management theory”. Whereas I do agree with the authors on most points, I am less convinced that “existing management theory” will suffice to address the problem of “reset thinking”. In this article, I demonstrate that the economy-bias of existing theories is a gateway for “reset thinking” geared towards an allegedly necessary re-/socialisation of management and organisation. A research agenda on cronyism must therefore be complemented by one on privilege and hierarchy not only as undesirable side-effects of cronyism, but also as desired outcomes of advocacy for specific minorities or missions. As self-identifications with group interests or calls for missions have become popular in management theory, I conclude that this new appetite for privilege might undermine not only the higher ideals of many management theorists, but also the foundations of modern society.","2023-09","2025-05-05 17:09:48","2025-05-05 17:09:48","","NA","","3","39","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND Publisher: ELSEVIER SCI LTD","","","","Management theory; Cronyism; Restorism; Stratification; The Great Reset; \n Conservatism","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The main focus of this research is to identify the risk factors associated with open-source software and the practices for those risks which will help software development companies and individuals to mitigate the risks. A systematic literature review (SLR) is employed for the identification of potential risk factors in OSS whereas questionnaire survey is used to validate the findings of the SLR from the relevant expert community. In the second round another SLR is carried out to identify the practices for softening the effect of risk-factors in OSS development. A total of 14 risk factors from the developers' perspective are identified via SLR in OSS. Amid the risk factors identified bugs, insufficient product documentation, and lack of communication and coordination among developers are considered the most important Further, we performed a secondary SLR to identify the practices for mitigating the effects of the risk factors in OSS. Therefore, a total of 31 practices for mitigating and addressing the risk factors in OSS were identified. In this work, we identified 14 risk factors and 31 practices for mitigating the critical risk factors, through SLR for adapting OSS development from developers' perspectives. We argue that focusing on the identified risk factors would minimize the risks associated with OSS.

It is debatable whether they should be used in open-source software (OSS) initiatives. There are studies examining the SRGMs' applicability in the OSS setting, but their scope is constrained by the models and projects they take into account, which could result in inconsistent findings. In this paper, the available SRGMs in the backdrop of OSS have been scrutinized and limitations have been identified. To address these limitations, a modification to the SRGMs using fuzzy neural networks (FNNs) has been proposed. In this paper, various SRGMs have been reviewed and sharp distinction among the same has been made, taking their respective failure intensity and mean value function under consideration. Through the failure intensity of software, it becomes a cakewalk to identify and predict the faults even before they actually arise and necessary and timely action may be initiated. After duly considering the review and contrast between the factors, a FNN model has been suggested for determination of software reliability differing with values of failure intensity and mean value function. First software failure data from a number of open-source software (OSS) projects have been gathered as part of the methodology used to modify traditional SRGMs. The proposed model gives out a high reliability rate and a low failure intensity. The most important factor is that it caters for the faults that are current and are being faced by the users on day to basis currently. It was found that the proposed model has a high success rate with the value of 82.6950937% which is considered as a successful result for software. The suggested FNN model may have a potential impact on the field of software reliability since FNN can handle the ambiguity and imprecision in the software failure data that are typical in open-source projects.","2023-07-04","2025-05-05 17:09:49","2025-05-05 17:09:49","","NA","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ONE NEW YORK PLAZA, SUITE 4600, NEW YORK, NY, UNITED STATES Publisher: SPRINGER","","","","Software reliability; Software reliability growth model; Failure intensity function; Mean value function; \n Logistic growth; Fuzzy neural\n network (FNN)","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Engineers and practitioners often resort to finite element (FE) software to advance this objective. Unfortunately, the availability of software equipped with boundary representation for absorbing scattered waves and ensuring consistent input ground motion prescriptions, which is necessary for accurately representing SSI effects, is currently limited. To address such limitations, the authors developed Seismo-VLAB (SVL v1.0-stable) an open-source software designed to perform SSI simulations. The methodology considers the integration of advanced techniques, including the domain decomposition method (DDM), perfectly matched layers (PMLs), and domain reduction method (DRM), in addition to parallel computing capabilities to accelerate the solution of large-scale problems. In this work, the authors provide a detailed description of the implementation for addressing SSI modeling, validate some of the SVL's features needed for such purpose, and demonstrate that the coupled DRM-PML technique is a necessary condition for accurately solving SSI problems. It is expected that SVL provides a significant contribution to the SSI research community, offering a self-contained and versatile alternative. The software's practical application in analyzing SSI and directionality effects on 3D structures under seismic loading demonstrates its capability to model real-world earthquake responses in structural engineering.","2023-11","2025-05-05 17:09:49","2025-05-05 17:09:49","","NA","","21","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, DNNs alone are susceptible to obvious mistakes that violate simple, common sense concepts and are limited in their ability to use explicit knowledge to guide their search and decision making. While overall DNN performance metrics may be good, these obvious errors, coupled with a lack of explainability, have prevented widespread adoption for crucial tasks such as medical image analysis. The purpose of this paper is to introduce SimpleMind, an open-source software environment for Cognitive AI focused on medical image understanding. It allows creation of a knowledge base that describes expected characteristics and relationships between image objects in an intuitive human-readable form. The knowledge base can then be applied to an input image to recognize and understand its content. SimpleMind brings thinking to DNNs by: (1) providing methods for reasoning with the knowledge base about image content, such as spatial inferencing and conditional reasoning to check DNN outputs; (2) applying process knowledge, in the form of general-purpose software agents, that are dynamically chained together to accomplish image preprocessing, DNN prediction, and result post-processing, and (3) performing automatic co-optimization of all knowledge base parameters to adapt agents to specific problems. SimpleMind enables reasoning on multiple detected objects to ensure consistency, providing cross-checking between DNN outputs. This machine reasoning improves the reliability and trustworthiness of DNNs through an interpretable model and explainable decisions. Proof-of-principle example applications are provided that demonstrate how SimpleMind supports and improves deep neural networks by embedding them within a Cognitive AI environment.","2023-04-13","2025-05-05 17:09:49","2025-05-05 17:09:49","","NA","","4","18","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Inspired by previous research, we advocate that the prediction models might benefit from leveraging social metrics. In this research, we investigate how to assist the new contributors in finding a task when onboarding a new project. To achieve our goal, we predict the skills needed to solve an open issue by labeling them with the categories of APIs declared in the source code (API-domain labels) that should be updated or implemented. Starting from a case study using one project and an empirical experiment, we found the API-domain labels were relevant to select an issue for a contribution. In the sequence, we investigated employing interviews and a survey of what strategies maintainers the strategies believe the communities have to adopt to assist the new contributors in finding a task. We also studied how maintainers think about new contributors' strategies to pick a task. We found maintainers, frequent contributors, and new contributors diverge about the importance of the communities and new contributors' strategies. The ongoing research works in three directions: 1) generalization of the approach, 2) Use of conversation data metrics for predictions, 3) Demonstration of the approach, and 4) Matching contributors and tasks skills.

This work proposes a general taxonomy for attacks on opensource supply chains, independent of specific programming languages or ecosystems, and covering all supply chain stages from code contributions to package distribution.

Design/methodology/approach This study focuses on dependencies using three network metrics - degree centrality, betweenness centrality and closeness centrality - in developer and module networks. A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks. Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.

Owing to the increase in demand for software products in various fields (big data, artificial intelligence, the Internet of Things, etc.), the software industry has expanded more than ever before. Therefore, software reliability has become very important, and efforts are being made to increase it. One of these efforts is the development of software reliability models (SRMs). SRMs have been studied for a long time as a model that predicts software reliability by using the number of software faults. Software failures can occur for several reasons, including independent software faults such as code errors and software hangs, as well as dependent cases where code errors lead to other software faults. Recently, due to the diversity of software operating environments, software faults are more likely to occur in a dependent manner, and, for this reason, they are likely to increase rapidly from the beginning and progress slowly to the maximum number thereafter. In addition, many large companies have focused on open-source software (OSS) development, and OSS is being developed by many users. In this study, we propose a new SRM that considers the number of finite faults and dependent faults, and examine the goodness-of-fit of a new SRM and other existing non-homogeneous Poisson process models based on the OSS datasets. Through numerical examples, the proposed model demonstrated a significantly better goodness-of-fit when compared to other existing models, and it also exhibited better results on the newly proposed integrated criteria.","2023","2025-05-05 17:09:50","2025-05-05 17:09:50","","11785-11804","","7","20","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

As there is currently no single diagnostic gold standard test, PCD is diagnosed by a combination of several methods comprising genetic testing and the examination of the ciliary structure and function. Among the approved diagnostic methods, only high-speed video microscopy (HSVM) allows to directly observe the ciliary motion and therefore, to directly assess ciliary function. In the present work, we present our recently developed freely available open-source software - termed “Cilialyzer”, which has been specifically designed to support and facilitate the analysis of the mucociliary activity in respiratory epithelial cells captured by high-speed video microscopy.Methods: In its current state, the Cilialyzer software enables clinical PCD analysts to load, preprocess and replay recorded image sequences as well as videos with a feature-rich replaying module facilitating the commonly performed qualitative visual assessment of ciliary function (including the assessment of the ciliary beat pattern). The image processing methods made accessible through an intuitive user interface allow clinical specialists to comfortably compute the ciliary beating frequency (CBF), the activity map and the “frequency correlation length” - an observable getting newly introduced. Furthermore, the Cilialyzer contains a simple-to-use particle tracking interface to determine the mucociliary transport speed.Results: Cilialyzer is fully written in the Python programming language and freely available under the terms of the MIT license. The proper functioning of the computational analysis methods constituting the Cilialyzer software is demonstrated by using simulated and representative sample data from clinical practice. Additionally, the software was used to analyze high-speed videos showing samples obtained from healthy controls and genetically confirmed PCD cases (DNAI1 and DNAH11 mutations) to show its clinical applicability.Conclusions: Cilialyzer serves as a useful clinical tool for PCD analysts and provides new quantitative information awaiting to be clinically evaluated using cohorts of PCD. As Cilialyzer is freely available under the terms of a permissive open-source license, it serves as a ground frame for further development of computational methods aiming at the quantification and automation of the analysis of mucociliary activity captured by HSVM.","2023-11","2025-05-05 17:09:50","2025-05-05 17:09:50","","NA","","NA","241","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Traditional methods of measuring node influence only consider some topology characteristics of the network, so the results are one-sided. Because there are different interactive behaviors among users in the community, it is necessary to mine more interaction information, so as to give a more comprehensive measure of node influence. In view of this, this paper proposes a method to maximize the node influence of open source software community based on a probability propagation model. Firstly, according to the relationship of users and their interactive records on projects, this paper quantifies the feedback of users on the project from three aspects (i.e. approve, save and modify) and establishes a new probability propagation model between users. Secondly, this paper proposes an algorithm(SIUF) to evaluate users' influence in the open source software community based on the probability propagation model. The algorithm fully considers the interaction behavior of users in the community. In the first stage, the user's own activity is taken as the initial ranking. In the second stage, the influence of neighbor nodes is taken into account, and the SIUF value of nodes is accumulated while the rich club effect is weakened. Finally, the proposed theory and method are applied to GitHub, a typical open source software community, and the correctness and effectiveness of this method are verified from influence spread and speed.","2023-08","2025-05-05 17:09:50","2025-05-05 17:09:50","","2386-2395","","4","10","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is a clonal B-cell disorder characterized by the proliferation of malignant plasma cells in the bone marrow, the presence of monoclonal serum immunoglobulin, and osteolytic lesions. An increasing amount of evidence shows that the interactions of MM cells and the bone microenvironment play a significant role, suggesting that these interactions may be good targets for therapy. The osteopontin-derived collagen-binding motif-bearing peptide NIPEP-OSS stimulates biomineralization and enhances bone remodeling dynamics. Due to its unique targeted osteogenic activity with a broad safety margin, we evaluated the potential of NIPEP-OSS for anti-myeloma activity using MM bone disease (MMBD) animal models. In a 5TGM1-engrafted NSG model, the survival rates of the control and treated groups were significantly different (p = 0.0014), with median survival times of 45 and 57 days, respectively. The bioluminescence analyses showed that myeloma slowly developed in the treated mice compared to the control mice in both models. NIPEP-OSS enhanced bone formation by increasing biomineralization in the bone. We also tested NIPEP-OSS in a well-established 5TGM1-engrafted C57BL/KaLwRij model. Similar to the previous model, the median survival times of the control and treated groups were significantly different (p = 0.0057), with 46 and 63 days, respectively.

This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 %, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 %. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic.

The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss (R) Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss (R)) and 10% collagen fibres in a block form and is sterilized by gamma-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss (R) Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss (R) Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.","2023-09-10","2025-05-05 17:09:51","2025-05-05 17:09:51","","NA","","NA","5","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: FLAT-RM C 16F, KINGS WING PLAZA 1, NO 3 KWAN ST, SHATIN, HONG KONG\n 00000, PEOPLES R CHINA Publisher: AME PUBLISHING COMPANY","","","","biomaterial; Bio-Oss (R) Collagen; case report; orthognathic; Orthognathic surgery; pseudoarthrosis treatment; vertical chin\n augmentation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In the project, we will use both quantitative and qualitative metrics to evaluate the health of OSS projects. The quantitative metrics will be gathered through automated crawling of meta information such as the number of contributors, commits and lines of code. Qualitative metrics will be gathered for selected “critical” projects through manual analysis and automated tools, including aspects such as sustainability, funding, community engagement and adherence to security policies. The results of the analysis will be presented on a user-friendly web platform, which will allow users to view the health of individual OSS projects as well as the overall health of the OSS ecosystem. With this approach, the CrOSSD project provides a comprehensive and up-to-date view of the health of OSS projects, making it easier for developers, maintainers and other stakeholders to understand the health of OSS projects and make informed decisions about their use and maintenance.","2023","2025-05-05 17:09:51","2025-05-05 17:09:51","","156-159","","NA","NA","","","","WWW '23 Companion","","","","","","English","","","","","","","Backup Publisher: Assoc Comp Machinery; Amazon Science; Baidu; Megagon Labs; Zhipu AI;\n Google; Booking Com; eBay; Bloomberg Engn; Netflix; ACM SIGWEB; Univ\n Texas Austin, Sch Informat; Data World; Inst Fdn Machine Learning ISBN: 978-1-4503-9416-1 Place: 1601 Broadway, 10th Floor, NEW YORK, NY, UNITED STATES Publisher: ASSOC COMPUTING MACHINERY","","","","software security; open-source software; open-source health; quality\n monitoring","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In this position paper, we draw attention to another perspective: scientific insight itself is a complex and collaborative artifact under continuous development and in need of continuous quality assurance, and as such, has many parallels to software artifacts. Considering current calls for more open, collaborative and reproducible science; increasing demands for public accountability on matters of scientific integrity and credibility; methodological challenges coming with transdisciplinary science; political and communication tensions when scientific insight on societally relevant topics is to be translated to policy; and struggles to incentivize and reward academics who truly want to move into these directions beyond traditional publishing habits and cultures, we make the parallels between the emerging open science requirements and concepts already well-known in (open-source) software engineering research more explicit.

However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors' engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors' attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.","2023-05-01","2025-05-05 17:09:52","2025-05-05 17:09:52","","3106-3130","","5","49","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1314 USA Publisher: IEEE COMPUTER SOC","","","","Organizations; Mentoring; Internet; Encoding; Codes; Taxonomy; Mentor; taxonomy; mentoring process; newcomer onboarding; summer of code; Task\n analysis; open source\n communities","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

One of the common practices during software development is the reuse of code. It can be achieved by utilizing libraries, frameworks, and other reusable components. Practically, when a fault is detected in replicated code, developers must check for similar faults in other copies, as there is a dependency between faults. To prevent recurrence of observed failures, developers must remove the corresponding leading fault and any related dependent faults. Many software reliability growth models (SRGMs) have been proposed and studied in the past, but most SRGMs assume that developers usually detect only one fault causing a failure. In actuality, it is necessary to consider the possibility of detecting multiple faults that may share similarities or dependencies. Additionally, some SRGMs rely on specific assumptions that may not always be valid, such as perfect debugging and/or immediate debugging. In this study, the modified diffusion models are proposed to handle these unrealistic situations, and are expected to better capture the dynamics of open source software (OSS) development. Experiments using real OSS data show that the proposed models can accurately describe the fault correction process of OSS. Finally, an optimal software release policy is proposed and studied. This policy takes into account some factors, including the remaining number of faults in the software, the expenses associated with identifying and rectifying those faults, and the level of market demand for the software. By considering these factors, developers can determine the optimal time to release the software to the market.","2023","2025-05-05 17:09:52","2025-05-05 17:09:52","","51631-51646","","NA","11","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We consider testing cost and system reliability, two critical dimensions, as the primary objectives, while also incorporating testing resource consumption as the third objective. The Non-dominated Sorting Genetic Algorithm II (NSGA-II) is chosen as the primary method for its effectiveness in MOEAs, with a special scenario outlined in the paper where NSGA-II may not guarantee optimal solutions.

Computed tomography (CT) is commonly used to overcome projection errors in two-dimensional angular measurements of dog hindlimb alignment. Three-dimensional volume rendering (VR) techniques permit virtual positioning and variable projection, but the final CT-image that defines the projection plane for angular measurements remains two-dimensional.Objective We wanted to develop a true three-dimensional open-source technique to measure the alignments of the hind limbs of dogs in CT scanners.Methods We developed an open-source 3D Slicer plug-in, to perform angular measurements using vector calculations in three-dimensional space. In 113 CT-scans of canine pelvic limbs, femoral torsion, femoral varus, femorotibial rotation, tibial torsion, tibial varus and tibiotalar rotation angles were calculated and compared to an already validated technique using VoXim (R).Results Reference points were identified and measurements were possible in the 113 acquisitions. The greatest difference between the two techniques was 1.4 degrees at only one tibial torsion angle. Mean values for all Bland-Altman plots did not show significant differences and were less than 0.07 degrees for all comparisons.Discussion Based on these results we considered angular measurements of canine hind limb alignment in CT scans using the 3D Slicer extension program sufficiently accurate for clinical orthopedic and surgical purposes in veterinary medicine.Conclusion With our open-source 3D Slicer extension software, we provide a free accessible tool for veterinary orthopedic surgeons and thus we hope to improve angular measurements in CT-scans of canine hind limb deformities through true three-dimensionality.","2024-03-29","2025-05-05 17:09:53","2025-05-05 17:09:53","","NA","","3","19","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA Publisher: PUBLIC LIBRARY SCIENCE","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Among the various techniques available, photoplethysmography stands out as particularly promising for assessing vital signs such as heart rate, respiratory rate, oxygen saturation, and blood pressure. Despite the efficacy of this method, many commercially available wearables, bearing Conformit & eacute; Europ & eacute;enne marks and the approval of the Food and Drug Administration, are often integrated within proprietary, closed data ecosystems and are very expensive. In an effort to democratize access to affordable wearable devices, our research endeavored to develop an open-source photoplethysmographic sensor utilizing off-the-shelf hardware and open-source software components. The primary aim of this investigation was to ascertain whether the combination of off-the-shelf hardware components and open-source software yielded vital-sign measurements (specifically heart rate and respiratory rate) comparable to those obtained from more expensive, commercially endorsed medical devices. Conducted as a prospective, single-center study, the research involved the assessment of fifteen participants for three minutes in four distinct positions, supine, seated, standing, and walking in place. The sensor consisted of four PulseSensors measuring photoplethysmographic signals with green light in reflection mode. Subsequent signal processing utilized various open-source Python packages. The heart rate assessment involved the comparison of three distinct methodologies, while the respiratory rate analysis entailed the evaluation of fifteen different algorithmic combinations. For one-minute average heart rates' determination, the Neurokit process pipeline achieved the best results in a seated position with a Spearman's coefficient of 0.9 and a mean difference of 0.59 BPM. For the respiratory rate, the combined utilization of Neurokit and Charlton algorithms yielded the most favorable outcomes with a Spearman's coefficient of 0.82 and a mean difference of 1.90 BrPM.

The endpoint of the baking process is traditionally determined by subjective human experts and indirect temperature measurements, which can often result in unstandardized production. Current colorimeters are unavailable for onsite measurement due to limitations associated with contact measurement and environmental temperature. Instead of the abovementioned human experts and tabletop colorimeters, a handheld colorimeter was built based on the expertise of human specialists and utilizing a tabletop colorimeter and other optical steps. First, the selected samples were used to determine the upper and lower limits distinguishing light, medium, and heavy baking levels by using a tabletop colorimeter. Second, independent light sources and spectrometers were utilized to choose the characteristic and reference wavelengths at 450 and 830 nm, separately. Third, the handheld colorimeter, instead of human expert observation, was designed with functions such as distance sensing and Internet of Things capabilities. The baked index was derived from the calibration reflection and established statistical models. Here, the calibration reflection was defined by the normalized intensity at 450 nm relative to 830 nm, and statistical models were founded from the determined samples of upper and lower limits at 95-700 mm. The developed handheld colorimeter demonstrated high agreement rates of 96.84% and 93.86% in separate comparisons with tabletop colorimeters and human experts, respectively. This work indicated the accurate and stable recognition of samples within two limits and overall. Field validation confirmed the performance of remote, economic, and onsite recognition against environmental temperature and noise.","2024-12-23","2025-05-05 17:09:53","2025-05-05 17:09:53","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In SRGM, the degree of reliability growth may fluctuate greatly according to change in the internal state of the software. It is called the change point (CP). Several researchers proposed the SRGM considering CP. In the open source software (OSS), there are many projects that continue development even after the software is released. Therefore, major updates with breaking changes may occur in it. The major updates can be a factor that causes a CP because it greatly changes the internal state of the OSS. This paper focuses on the relationship between CP and software updates. We collect OSS fault data from a bug tracking system. Moreover, we examine the behavior of SRGM before and after software updates. Furthermore, we discuss the applicability of SRGM for CP in OSS. Also, we compare the proposed model based on CP with the model without CP. As a result, we have confirmed that the SRGM can evaluate the reliability in the environment with major updates. Moreover, the proposed method performs better than without considering CP model. Especially, the exponential model's mean value function is the suitable method to assess the OSS reliability for the proposed method.","2024-08","2025-05-05 17:09:53","2025-05-05 17:09:53","","NA","","04","31","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

OSS has transformed how software is developed, distributed, and maintained. This increase in popularity has led to extensive research in various domains of OSS, such as evolution, adoption, community and development processes.With the passage of time the volume of academic studies increased in the area of OSS, including Systematic Literature Reviews (SLRs) and Systematic Mapping Studies (SMS), which have provided valuable insights into specific aspects of OSS. The OSS domain is vast, with many areas that are still under explored. The fragmented nature of the existing studies presents challenges for both researchers and practitioners in identifying comprehensive research trends, gaps, future directions, and the cohesive understanding of the broader trends within the field. The secondary studies synthesize the literature to highlight findings and gaps of an area. The fragmentation of OSS academic literature limits the ability of researchers to identify unexplored or under-researched areas. This also creates challenges for both practitioners and researchers, as they lack awareness of the best practices, tools, technologies, and methodologies in a OSS domain. This study is motivated by the need to consolidate the extensive research conducted in the OSS domain, providing a holistic view that can guide future investigations and practical applications. The rationale for conducting this research lies in the opportunity to aggregate and classify existing OSS research areas, topics, and future directions through a systematic tertiary study. By synthesizing the findings from secondary studies, this research aims to offer a meta-level understanding of the OSS field, uncovering overlooked areas and defining a research agenda. The systematic approach, guided by the established protocol of Kitchenham, ensures that the study is conducted rigorously, with a focus on comprehensiveness and reliability. Ultimately, this research seeks to contribute to the OSS community by highlighting key research areas that require further exploration, thereby advancing the field and supporting the continued growth and innovation within OSS development. A systematic tertiary study is performed to cover all the systematic secondary studies in the area of OSS. The guidelines of Kitchenham are used for designing the protocol. The protocol details the research objectives, scope, search strategy, data extraction, quality assessment and synthesis. The protocol is detailed in section three for transparency. We have identified seventy-four studies that consist of twenty-five SMS and forty-nine SLR. The literature is mapped to a published taxonomy of OSS by Aksulu and Wade, however, the future directions are thematically analyzed. The results of mapping show that the highest number of studies (forty-seven) are in the sub-category of “OSS categorization/research agenda”, whereas eight studies are mapped to the subcategory “OSS vs Proprietary”. Both of these sub-categories fall in the main category of “Conceptual”. The second major work is in the “OSS Production” category in the sub-categories of “Communities” (ten), “Process” (eight), “User and Developer Motivation” (nine), and “Self-Organization (Product and Community Evolution)” (six). Seven studies are also mapped to the sub-category of “Software Quality” in the main category of “Performance Metrics”. Other categories have fewer studies mapped to them. The areas identified, thematically, for future directions are “OSS contributors”, “OSS development process”, “OSS evolution and prediction”, “use of OSS in different domains”, and “OSS adoption/adaptation/integration”. The mapping between “key research areas” of systematic secondary studies and “taxonomy categories” shows that there is no or little research in some of the categories of taxonomy, having potential of future research. The future directions thematic analysis will also aid researchers and practitioners.","2024","2025-05-05 17:09:54","2025-05-05 17:09:54","","189952-189993","","NA","12","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, the existing literature implicitly takes a static view that software structure and organizational structure are established early on and change slowly over time, if at all. Such a view does not fully reflect the complex and dynamic nature of software development and tends to overlook the role played by human agents as they ramp involvement up and down over time. This study considers that coordination practice plays an important role in altering technical interdependencies in OSS development. This study investigates coordination practices that result in changes in software coupling-in particular, increases in software coupling. This study automatically analyzes the code in 72 software releases and 1033 task episodes of three successful OSS projects-GNU grep, IPython, and Scikit-image. This study takes a fine-grained practice-oriented perspective that views the way that the work is done as constituting the organization. In our conceptualization, OSS contributors use a configuration of multiple organizational elements, enacted and varying across specific episodes of practice. In line with this perspective, this study takes a configurational approach, uses fuzzy-set qualitative comparative analysis (fsQCA) to analyze episodes that led to decreases, no changes, and increases in software coupling during the inter-release periods in which the level of software coupling increased significantly, which we call focal period. We find that co-work involving multiple individuals tends to result in code that adds technical dependencies (increases in software coupling) during the focal period. To illustrate this beyond our fuzzy-set analysis, we present and discuss three episodes in narrative detail. The fine-grained, configurational analysis in this study supports the idea that the organizing process is ongoing enactment. In this study, OSS systems are an amalgam of code that builds up in different episodes each possibly different organizational configurations, rather than thinking of the OSS systems or projects as static or singular.","2024-03","2025-05-05 17:09:54","2025-05-05 17:09:54","","NA","","1","34","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD","","","","Online communities; Modularity; Configuration; Coupling; Open sources software; \n Organizing","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects.","2024-05","2025-05-05 17:09:54","2025-05-05 17:09:54","","NA","","5","36","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","software evolution; assessment model; open source software engineering; \n software resilience","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Therefore, in this paper, we conduct a large-scale measurement and a systematic analysis to reveal the attack surfaces of the CI/CD pipeline and quantify their security impacts. Specifically, for the measurement, we collect a data set of 320,000+ CI/CD pipeline-configured GitHub repositories and build an analysis tool to parse the CI/CD pipelines and extract security-critical usages. Our measurement reveals that the script runtimes are prone to code hiding while the script usage update is not in time, giving attackers chances to hide malicious code and exploit existing vulnerabilities. Moreover, even the scripts from verified creators may contain severe vulnerabilities. Besides current CI/CD ecosystem heavily relies on several core scripts, which may lead to a single point of failure. While the CI/CD pipelines contain sensitive information/operations, making them the attacker's favorite targets. Inspired by the measurement findings, we abstract the threat model and the attack approach toward CI/CD pipelines, followed by a systematic analysis of attack surfaces, attack strategies, and the corresponding impacts. We further launch case studies on five attacks in real-world CI/CD environments to validate the revealed attack surfaces.

These laws, such as the European Union’s General Data Protection Regulation (GDPR), require software developers to meet privacy-related requirements when interacting with users’ data. Prior research describes the impact of such laws on software development, but only for commercial software. Although open-source software is commonly integrated into regulated software, and thus must be engineered or adapted for compliance, we do not know how such laws impact open-source software development. Aims: To understand how data privacy laws affect open-source software (OSS) development, we focus on the European Union’s GDPR, as it is the most prominent such law. We investigated how GDPR compliance activities influence OSS developer activity (RQ1), how OSS developers perceive fulfilling GDPR requirements (RQ2), the most challenging GDPR requirements to implement (RQ3), and how OSS developers assess GDPR compliance (RQ4). Method: We distributed an online survey to explore perceptions of GDPR implementations from open-source developers (N=56). To augment this analysis, we further conducted a repository mining study to analyze development metrics on pull requests (N=31,462) submitted to open-source GitHub repositories. Results: Our results suggest GDPR policies complicate OSS development and introduce challenges, primarily regarding the management of users’ data, implementation costs and time, and assessments of compliance. Moreover, we observed negative perceptions of the GDPR from OSS developers and significant increases in development activity, in particular metrics related to coding and reviewing, on GitHub pull requests related to GDPR compliance. Conclusions: Our findings provide future research directions and implications for improving data privacy policies, motivating the need for relevant resources and automated tools to support data privacy regulation implementation and compliance efforts in OSS.","2024","2025-05-05 17:09:55","2025-05-05 17:09:55","","325–336","","NA","NA","","","","ESEM '24","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9798400710476 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","Open-Source Software; Data Privacy; Regulatory Compliance","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In order to meet user needs and functional changes, open-source software continuously improves its software quality through successive releases. Due to the iterative development process of open-source software, open-source software testing also requires continuous learning to understand the changes in the software. Therefore, the fault detection process of open-source software involves a learning process. Additionally, the complexity and uncertainty of the open-source software development process also lead to stochastically introduced faults when troubleshooting in the open-source software debugging process. Considering the phenomenon of learning factors and the random introduction of faults during the testing process of open-source software, this paper proposes a reliability modeling method for open-source software that considers learning factors and the random introduction of faults. Least square estimation and maximal likelihood estimation are used to determine the model parameters. Four fault data sets from Apache open-source software projects are used to compare the model performances. Experimental results indicate that the proposed model is superior to other models. The proposed model can accurately predict the number of remaining faults in the open-source software and be used for actual open-source software reliability evaluation.","2024-01","2025-05-05 17:09:55","2025-05-05 17:09:55","","NA","","2","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","open-source software; learning factors; software reliability model; stochastic differential equation; \n stochastically introduced faults","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

It is important to deepen our understanding of spoofing attacks and develop resilient techniques to effectively combat this threat. Detecting and mitigating these attacks requires thorough testing, typically conducted in a laboratory environment through the establishment of a spoofing test-bed. The complexity, cost and resource demands of creating such a test-bed underscore the necessity of utilizing openly available datasets. To address this need, this paper introduces a new GNSS spoofing data repository from Finnish Geospatial Research Institute (FGI) named hereafter as `FGI-SpoofRepo'. This data repository consists of raw In-phase and Quadrature (I/Q) data of live recordings of GPS L1 C/A, Galileo E1, GPS L5, and Galileo E5a signals. These datasets encompass three distinct types of spoofing characteristics (synchronous, asynchronous, and meaconing), making them very useful example candidates of open data for testing the performance of any anti-spoofing techniques (be it detection or mitigation). The inclusion of live signals in multiple GNSS frequencies and the presence of cryptographic signatures in Galileo E1 signal make these datasets potential benchmarks for assessing the resilience performance of multi-frequency multi-constellation receivers. The analysis of the datasets is carried out with an open-source MATLAB-based software-defined receiver, FGI-GSRx. An updated version of FGI-GSRx, equipped with the necessary modifications for processing and analyzing the new datasets, is released alongside the datasets. Therefore, the GNSS research community can utilize the open-source FGI-GSRx or any third-party SDR to process the publicly available raw I/Q data for implementation, testing and validation of any new anti-spoofing technique. The results show that time-synchronous spoofing seamlessly takes over positioning solution, while time-asynchronous spoofing acts as noise or in some cases, completely prevent the receiver from providing a positioning solution. Signal re-acquisition during an ongoing spoofing attack (cold start), the receiver tends to lock onto the spoofing signal with the highest peak, posing a potential threat to GNSS receivers without assisted information. Overall, this research aims to advance the understanding of complex spoofing attacks on GNSS signals, providing insight into enhancing resilience in navigation systems.","2024-10","2025-05-05 17:09:55","2025-05-05 17:09:55","","NA","","4","28","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A total of 2763 Asian Americans aged 20 and older were included in this analysis. The primary predictor, acculturation score, was determined by three questions: (i) language spoken at home (higher score for English), (ii) country of birth (higher score for United States) and (iii) length of time in the United States. Dental floss use, dental visits and unmet dental care needs were included as outcomes in this study. Descriptive statistics and logistic regressions were used to analyse the samples.ResultsAcculturation was significantly associated with dental health behaviours: Individuals with higher levels of acculturation were more likely than less acculturated individuals to use dental floss (81.0% vs. 63.9%, respectively) and visit the dentist regularly (76.7% vs. 66.9% respectively). Insurance status moderated the association between acculturation and dental visits: Acculturation was significantly associated with dental visits in the past year among insured individuals (OR = 1.70, 95% CI: 1.29-2.23), but not among uninsured individuals. Unmet dental care needs were present in 11.1% of participants. While costs and insurance were the top two determinants of access to care, individuals with and without insurance differed with regard to their third major reason for unmet dental care needs: Being `too busy' and not wanting to spend money on dental care.ConclusionsAmong the Asian population in the United States, those with high acculturation scores were more likely to engage in dental flossing and visit the dentist regularly compared to those Asians with lower acculturation scores. To encourage dental flossing and regular dental visits among Asians with lower acculturation scores, cultural adaptation and language accessibility suggests being considered. Future research is necessary to confirm the moderating effect of insurance status on the association between acculturation and regular dental visits. Additionally, our findings emphasize the impact of costs and insurance on access to dental care among Asians in the United States, highlighting the importance of future public health programmes in addressing these barriers.","2024-02","2025-05-05 17:09:57","2025-05-05 17:09:57","","101-110","","1","52","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In contrast, breast ultrasound imaging (BUS) can contain many irregularities not indicated by scan metadata, such as enhanced scan modes, sonographer annotations, or additional views. We present an open-source software solution for automatically processing clinical BUS datasets. The algorithm performs BUS scan filtering (flagging of invalid and non-B-mode scans), cleaning (dual-view scan detection, scan area cropping, and caliper detection), and knowledge extraction (BI-RADS Labeling and Measurement fields) from sonographer annotations. Its modular design enables users to adapt it to new settings. Experiments on an internal testing dataset of 430 clinical BUS images achieve >95% sensitivity and >98% specificity in detecting every type of text annotation, >98% sensitivity and specificity in detecting scans with blood flow highlighting, alternative scan modes, or invalid scans. A case study on a completely external, public dataset of BUS scans found that BUSClean identified text annotations and scans with blood flow highlighting with 88.6% and 90.9% sensitivity and 98.3% and 99.9% specificity, respectively. Adaptation of the lesion caliper detection method to account for a type of caliper specific to the case study demonstrates the intended use of BUSClean in new data distributions and improved performance in lesion caliper detection from 43.3% and 93.3% out-of-the-box to 92.1% and 92.3% sensitivity and specificity, respectively.

They use various technologies to create solutions that boost and advance healthcare systems and healthcare delivery. Open-source software (OSS) technology has become an essential component of startups' toolkits, providing various advantages, such as free access to source codes and opportunities for innovation. Research on OSS in healthcare startups is limited, so our study aims to investigate how healthtech startups perceive the influence of OSS on product development and to identify the challenges they face. To meet this objective, we conducted an empirical study with six health-tech startups, using semi-structured interviews. Thematic analysiswas performed on the collected data to identify common themes and subthemes related to the research objective. The findings showed that health-tech startups benefit from the cost efficiency, scalability, and customization of OSS. Open-source software tools, reshape development and promote efficient code management, provide community support, and reduce costs. However, they demand OSS knowledge, management of updates, regulatory compliance, and heightened cybersecurity. Our study adds to the body of knowledge on OSS and healthcare startups and the connection between them. We provide recommendations for health-tech startups, such as embracing OSS tools for their benefits, investing in education and training, and engaging with the OSS community for comprehensive support in their product development processes.","2024","2025-05-05 17:09:57","2025-05-05 17:09:57","","265-282","","NA","500","","","","Lecture Notes in Business Information Processing","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 978-3-031-53226-9; 978-3-031-53227-6 Place: NA Publisher: NA","","","","NA","","Hyrynsalmi, S.; Munch, J.; Smolander, K.; Melegati, J.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Different acquisition modes, such as whole-cell patch-clamp recordings in the current or voltage clamp configuration, capacitance measurements or single channel recordings from cultured cells as well as acute brain slices are routinely performed for these purposes. Nevertheless, multipurpose transparent and adaptable software tools to perform reproducible state-of-the-art analysis of multiple experiment types and to manage larger sets of experimental data are currently unavailable. Methods: Biophysical Essentials (BPE) was developed as an open-source full stack python software for transparent and reproducible analysis of electrophysiological recordings. For validation, BPE results were compared with manually analyzed single-cell patch-clamp data acquired from a human in vitro nociceptor-model and mouse dorsal root ganglia neurons. Results: While initially designed to improve time consuming and repetitive analysis steps, BPE was further optimized as a technical software solution for entire workflow processing including data acquisition, data preprocessing, normalization and visualization and of single recordings up to stacked calculations and statistics of multiple experiments. BPE can operate with different file formats from different amplifier systems and producers. An in-process database logs all analysis steps reproducible review and serves as a central storage point for recordings. Statistical testing as well as advanced analysis functions like Boltzmann-fitting and dimensional reduction methods further support the researchers' needs in projects involving electrophysiology techniques. Conclusions: BPE extends beyond available patch-clamp specific, open source - and commercial analysis tools in particular because of reproducible and sharable analysis workflows. BPE enables full analysis from raw data acquisition to publication ready result visualizations - all within one single program. Thereby, BPE significantly enhances transparency in the analytical process of patch-clamp data analysis. BPEs function scope is completely accessible through an easy-to-use graphical user interface eliminating the need for programing language proficiency as required by many community patch-clamp analysis frameworks and algorithms.","2024-10","2025-05-05 17:09:57","2025-05-05 17:09:57","","NA","","NA","255","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

A key challenge in DFN model parameterization is that parameters measured from cell tear-down experiments cannot be directly used in simulations, and parameter identification is required to accurately reflect real-world battery dynamics However, existing open-source DFN codes lack the capability to perform parameter identification and operate in open-loop mode. COBRAPRO addresses this gap by implementing a systematic parameterization pipeline to accurately determine parameters using battery current and voltage data. Concepts from structural and practical identifiability are utilized to determine parameters that can be fixed to their experimental values and parameters that are suitable for optimization. In the parameter identification process, particle swarm optimization is used to minimize the error between experimental data and simulation results. Additionally, COBRAPRO incorporates a robust method to determine consistent initial conditions and utilizes a fast numerical solver for improved performance. We demonstrate COBRAPRO's parameter identification framework on reference performance test data obtained from LG INR21700-M50T cells. The parameterized model is validated against driving cycle data, showing good agreement between the experimental and simulation results.","2024-09-02","2025-05-05 17:09:58","2025-05-05 17:09:58","","NA","","9","171","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In polluted days, we identified a total of 5,147 organic molecules, including 1,206 OS molecules. The average molecular weight (m.w.) and carbon chain length of OSs in this study exceeded the commonly recognized range (500 Da). OSs were mostly composed of newly formed low oxidation state compounds as well as aged aliphatic and aromatic ones. The number and abundance of aromatic and aliphatic OSs with low saturation, volatility, O/C-w as well as H/C-w increased greatly with rising PM2.5 concentrations. The daytime photo-oxidation resulted in a large number of high m.w. (HMW, > 500 Da) OSs. OSs with m.w. <500 Da, and many oxygen atoms were newly generated during the nighttime, mainly dominated by liquid-phase oxidation processes. The result of OSs with higher m.w. and lower volatility was due to increased dimerization and oligomerization. During pollution formatting, OSs with small DBE values (between 0 and 6) appeared; meanwhile, the number of highly unsaturated OSs with DBE > 7 (mainly aromatic OSs) increased by about 34%.

However, there is little knowledge about the extent to which OSS community members engage in usability issue discussions, the aspects of usability they frequently target, and the characteristics of their collaboration around usability issue discussions. This knowledge is important for providing practical recommendations and research directions to better support OSS communities in addressing this important topic and improve OSS usability in general. To help achieve this goal, we performed an extensive empirical study on issues discussed in five popular OSS applications: three data science notebook projects (Jupyter Lab, Google Colab, and CoCalc) and two code editor projects (VSCode and Atom). Our results indicated that while usability issues are extensively discussed in the OSS projects, their scope tended to be limited to efficiency and aesthetics. Additionally, these issues are more frequently posted by experienced community members and display distinguishable characteristics, such as involving more visual communication and more participants. Our results provide important implications that can inform the OSS practitioners to better engage the community in usability issue discussion and shed light on future research efforts toward collaboration techniques and tools for discussing niche topics in diverse communities, such as the usability issues in the OSS context.","2024-04","2025-05-05 17:09:58","2025-05-05 17:09:58","","NA","","CSCW1","8","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software; usability; issue tracking systems","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In addition, we propose a two‐stage training method to alleviate the catastrophic changes in the pre‐training parameters and loss of the initially learned knowledge caused by direct training of PIFTNet.

We examine how projects engage in distinct “discursive modulation practices” to imprint the community's shared core doctrines and design principles onto the software thereby shaping its novelty and complexity. We borrow the concept of modulation from audio synthesis to explain how a preexisting signal-in our case, the ongoing community discourse-is modulated to produce varying sounds-in our case, the novelty and complexity of the software. The concept of modulation offers a lens to understand how emergent, community-wide development activities are influenced by filtering discursive positions and mixing those positions, thereby shaping the artifact's novelty and complexity. Our research shows that the modulation of novelty exhibits a range from “proximal” to “distal” searches for new features, while the modulation of complexity varies between “integration” and “deprecation.” By drawing on these concepts, we formulate a theory that explains how modulation results in alternative OSS community approaches to shaping software novelty and complexity and how this process reflects and is reflected in the resulting software artifact.","2024-12","2025-05-05 17:09:58","2025-05-05 17:09:58","","1395-1422","","4","48","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Virtual communities; Software engineering; Social networks; Software development; Innovations; Hierarchies; Complexity; Artifacts; Collaborative learning; Modulation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In response to this challenge, our paper presents an innovative named entity recognition (NER) framework (https://github. com/NeuralSentinel/DistALANER) tailored for the open-source software domain. Our method stands out by employing a distantly supervised, two-step annotation process that cleverly exploits language heuristics, bespoke lookup tables, external knowledge bases, and an active learning model. This multifaceted strategy not only elevates model performance but also addresses the critical hurdles of high costs and the dearth of expert annotators. A notable achievement of our approach is its capability to enable pre-large language models (pre-LLMs) to significantly outperform specially designed generic/domain specific LLMs for NER tasks.

The most important contribution of this paper is introducing a practical and effective software tool that facilitates decision-making analysis based on the fuzzy analytical hierarchy process, thereby allowing better-informed choices on concept selection, as it has been designed with a specific focus on the engineering field. In this paper we describe the key concepts of ELIGERE and its modalities of use in several real use cases. Finally, we compare ELIGERE with the widely used general purpose decision support software based on the fuzzy analytical hierarchy process.","2024-01","2025-05-05 17:09:59","2025-05-05 17:09:59","","509-524","","1","18","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY Publisher: SPRINGER HEIDELBERG","","","","Decision support systems; Concept selection; Engineering design; System\n evaluation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The National Aeronautics and Space Administration (NASA) Armstrong Flight Research Center (AFRC) (Edwards, California) has been developing an optical fiber-based sensing suite called Fiber Optics Sensing System (FOSS) over the past two decades. Successful strain monitoring flight demonstrations such as the NASA Ikhana (General Atomics, San Diego, California) remotely piloted aircraft and the X-56A Multi-Utility Technology Testbed (Lockheed Martin Corporation, Bethesda, Maryland) remotely piloted subscale aircraft have been performed. Interest in adapting fiber-optic sensors for aerospace applications has led to commissioning the development of a ruggedized FOSS system for spaceflight through the NASA Launch Services Program (LSP) at the NASA Kennedy Space Center (KSC) (Merritt Island, Florida). In this paper, a ruggedized FOSS suitable for a launch environment is discussed in detail. Thermal analysis and enclosure design will be discussed as well as environmental testing such as shock, random vibration, thermal vacuum, and electromagnetic interference/electromagnetic compatibility (EMI/EMC). With all relevant environmental testing completed, a ruggedized FOSS unit has successfully passed all testing and is now deemed space-launch ready.","2024","2025-05-05 17:09:59","2025-05-05 17:09:59","","NA","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: AIAA ISBN: 978-1-62410-711-5 Place: 1801 ALEXANDER BELL DR, STE 500, RESTON, VA 20191-4344 USA Publisher: AMER INST AERONAUTICS & ASTRONAUTICS","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In response to this challenge, our paper presents an innovative named entity recognition (NER) framework () tailored for the open-source software domain. Our method stands out by employing a distantly supervised, two-step annotation process that cleverly exploits language heuristics, bespoke lookup tables, external knowledge bases, and an active learning model. This multifaceted strategy not only elevates model performance but also addresses the critical hurdles of high costs and the dearth of expert annotators.

Materials and methods Seventy-five adult subjects showing approximately 40% proximal gingival bleeding were randomized to receive OHt (1 session weekly over 8 weeks) using toothbrush and dental floss or toothbrush alone. The subjects were then followed over 180 days without professional guidance. Primary outcomes were mean interproximal Gingival Index (GI) and GI = 2 (gingival bleeding). Mixed linear models were used for the comparison between groups (p < 0.05). Results68 subjects received OHt, 48 subjects completed the 180-day follow-up. Subjects maintained adequate oral hygiene routines. Besides a reduction in gingival inflammation, no alterations in gingival status were observed among groups, subjects additionally instructed to use dental floss showing a mean interproximal GI = 2 of 12.8 +/- 2.5 compared with 19.8 +/- 2.2 for subjects limited to tooth brushing alone. Conclusions OHt intensive training promotes gingival health and maintenance lasting at least 6 months without professional supervision reinforcing important principles: (i) dental health professionals should dedicate time training and motivating their patients to reach adequate self-performed plaque control; and (ii) the adjunctive use of dental floss appears essential to reduce interproximal gingival inflammation in subjects with intact interdental papillae. Clinical relevance Dentists need to invest time in training/motivating/engage their patients to achieve adequate OH; adjunct flossing in subjects with papilla filling the interdental space appears essential to reach and maintain gingival health.

This research seeks to address the existing gap in accessible tools for high-throughput analysis of endothelial tube formation and cell invasion in vitro, facilitating the rapid assessment of drug sensitivity.MethodsOur approach involved annotating over 1000 2 mm Z-stacks of cancer and endothelial cell co-culture model and training machine learning models to automatically calculate cell coverage, cancer invasion depth, and microvessel dynamics. Specifically, cell coverage area was computed using focus stacking and Gaussian mixture models to generate thresholded Z-projections. Cancer invasion depth was determined using a ResNet-50 binary classification model, identifying which Z-planes contained invaded cells and measuring the total invasion depth. Lastly, microvessel dynamics were assessed through a U-Net Xception-style segmentation model for vessel prediction, the DisPerSE algorithm to extract an embedded graph, then graph analysis to quantify microvessel length and connectivity. To further validate our software, we reanalyzed an image set from a high-throughput drug screen involving a chemotherapy agent on a 3D cervical and endothelial co-culture model. Lastly, we applied this software to two naive image datasets from coculture lumen and microvascular fragment models.ResultsThe software accurately measured cell coverage, cancer invasion, and microvessel length, yielding drug sensitivity IC50 values with a 95% confidence level compared to manual calculations. This approach significantly reduced the image processing time from weeks down to h. Furthermore, the software was able to calculate cell coverage, microvessel length, and invasion depth from two additional microphysiological models that were imaged with confocal microscopy, highlighting the versatility of the software.ConclusionsOur free and open source software offers an automated solution for quantifying 3D cell behavior in microphysiological models assessed using non-confocal microscopy, providing the broader Cellular and Molecular Bioengineering community with an alternative to standard confocal microscopy paired with proprietary software.This software can be found in our GitHub repository: https://github.com/fogg-lab/tissue-model-analysis-tools.","2024-10-10","2025-05-05 17:09:59","2025-05-05 17:09:59","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Addressing a significant knowledge gap affecting this structural type, the study reveals how daily and seasonal fluctuations in environmental factors have a notable influence on its experimental modal parameters. A robust frequency-domain tracking algorithm is first developed to identify and follow the evolution of modal parameters over time, exploiting ambient vibration recordings acquired at sub-daily intervals on the structures. The procedure is systematically applied to the entire portfolio of case-study buildings and, in the first year of training, integrated with measurements of environmental parameters provided by nearby weather stations. The multivariate regression analysis indicates that temperature variation is the primary driver of the observed wandering of natural frequencies. The frequency-temperature relationship shows a positive correlation above zero degrees and, in several cases, a significant degree of nonlinearity already present in low-frequency global modes. Simple predictive models are proposed to address such nonlinear behavior, including freezing conditions and accounting for internal heating during winter. Leveraging these novel insights, the work develops strategies to improve the efficiency of data acquisition protocols and training periods, enabling the near-future extension of real-time condition assessment methodologies to the entire OSS network.","2024-09-10","2025-05-05 17:09:59","2025-05-05 17:09:59","","NA","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Effective regeneration of bone defects resulting from peri-implantitis is crucial to maintaining the functionality of dental implants. Purpose of the Study: The study aimed to compare the effectiveness of fine-particle dentin and Bio-Oss in the reconstruction of bone defects caused by peri-implantitis. Materials and Methods: The study included a comprehensive radiological assessment of changes in bone density over time. Bone density was assessed using Hounsfield Units (HUs) as a measure of bone attenuation, with radiological assessments performed at 8- and 12-week intervals during the healing process. The study included participants ranging in age from 30 to 65 years. Fifty-seven patients were divided into three groups: 22 patients received small-particle dentin, 15 received Bio-Oss, and 20 controls without bone substitute material. Results: The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine dentin group, 85% in the Bio-Oss group, and 70% in the control group. The fine-dentin group showed a 20% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95% successful integration in the fine-dentin group, 85% in the Bio-Oss group, and 70% in the control group. Conclusions: Both fine-particle dentin and Bio-Oss significantly improved bone density compared to the control group. Fine-particle dentin is suitable for immediate bone regeneration due to its rapid initial regeneration, while Bio-Oss provides long-term support, ideal for maintaining implant stability over a longer period of time. The results highlight the importance of selecting appropriate bone replacement materials depending on the clinical scenario to improve patient outcomes after dental implant placement.","2024-08","2025-05-05 17:10:00","2025-05-05 17:10:00","","NA","","16","13","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","bone regeneration; bone substitute materials; periimplantitis; small-particle dentin; \n Bio-Oss","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In contrast to companies, open-source software projects cannot easily enforce security guidelines for development environments. Instead, contributors' security setups are likely heterogeneous regarding chosen technologies and strategies. To the best of our knowledge, we perform the first in-depth qualitative investigation of the security of open-source software contributors' individual security setups, their motivation, decision-making, and sentiments, and the potential impact on open-source software supply chain security. Therefore, we conduct 20 semi-structured interviews with a diverse set of experienced contributors to critical open-source software projects. Overall, we find that contributors have a generally high affinity for security. However, security practices are rarely discussed in the community or enforced by projects.

The challenges are mainly concerned with (i) fine-grained unknown attack detection and (ii) ever-changing legitimate traffic adaptation. To tackle these problem, we present three key design norms. The core idea is to construct a model to split the data distribution hyperplane and leverage the concept of isolation, as well as advance the incremental model update. We utilize the isolation tree as the backbone to design our model, named FOSS, to echo back three norms. By analyzing the popular dataset of network intrusion traces, we show that FOSS significantly outperforms the state-of-the-art methods. Further, we perform an initial deployment of FOSS by working with the Internet Service Provider (ISP) to detect distributed denial of service (DDoS) attacks.

The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context. Can rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.","2024-12","2025-05-05 17:10:00","2025-05-05 17:10:00","","1449-1469","","4","63","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Publisher: SPRINGER","","","","OSS; Open-source software; Entrepreneurship; Trust; Crowdfunding; L26; O30; O36; \n O34","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To overcome the problem of inherent computational complexity, a fractional-order filter is applied to approach the virtual controller and its fractional-order derivative in each step of the backstepping procedure. The barrier Lyapunov function (BLF) is employed to handle the state constraints, and finite-time stability criteria on the basis of fractional-order Lyapunov method are introduced to prove the finite-time convergence of the tracking error into a small region around the origin.

Nowadays, it is becoming challenging to procure bone legally, resulting in medical students' inadequacy of bone. Plaster -of -Paris or resin bone models sold on the market are less detailed than real bones. Aims and objectives This study aims to create a three-dimensional (3D)-printed human bone model with free, open-source software and fused deposition modelling (FDM) 3D printers, compare its accuracy with the original bones and validate it with a textbook description. Methods Scapula and hip bone models were produced using open-source software 3D Slicer from computed tomography (CT) data from the “New Mexico Decedent Image Database”. After automated segmentation, bones were edited manually with tools in a 3D Slicer (https://www.slicer.org/) and Meshmixer software (Autodesk Inc., San Rafael, California, United States) and 3D bone models were printed using polylactic (PLA) filament. Results and discussions 3D digital models of both bones were successfully created with the maximum possible accuracy with an FDM 3D printer. A 3D digital replica of the scapula obtained after segmentation retained most anatomical features except for the glenoid cavity, as the head of the humerus obscured the glenoid cavity. The 3D digital skeleton of the hip bone retained all anatomical features except articulating surfaces, such as the acetabulum and auricular surface ilium, which were obscured by the head of the femur and sacrum. A few morphological features of both bones differed from the original dry bone, and a few finer details were unclear in the iliac fossa and ischium. After manual editing and post -processing, the final physical model obtained has all the features. Conclusions We conclude that it is possible to produce anatomically accurate models with the greatest possible resemblance and accuracy to the original bones using free and open-source data with an FDM 3D printer.","2024-05-13","2025-05-05 17:10:01","2025-05-05 17:10:01","","NA","","5","16","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: CAMPUS, 4 CRINAN ST, LONDON, N1 9XW, ENGLAND Publisher: SPRINGERNATURE","","","","3d printing; 3d slicer; image segmentation; innominate; scapula","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Mentoring allows contributors to improve their technical skills and learn about the protocols and cultural norms of the project. However, mentoring has its challenges: mentors sometimes feel unappreciated, and mentees may have mismatched interests or lack interpersonal skills. Existing research has investigated the different challenges of mentoring in different OSS contexts, but we lack a holistic understanding. Objective: A comprehensive understanding of the current practices and challenges of mentoring in OSS is needed to implement appropriate strategies to facilitate mentoring. Method: This study presents a systematic literature review investigating how literature has characterized mentoring practices in OSS, including their challenges and the strategies to mitigate them. We retrieved 232 studies from four digital libraries. Out of these, 21 were primary studies. Using this, we performed backward and author snowballing, adding another 27 studies. We conducted a completeness check by reviewing the references of the 4 most relevant primary studies, which resulted in us adding 1 additional study. We then conducted a full-text review and evaluated the studies using a set of criteria; as a result, 10 papers were excluded. We then employed an open-coding approach to analyze, aggregate, and synthesize the selected studies. Results: We reviewed 39 studies to investigate the different facets of mentoring in OSS, encompassing motivations, goals, channels, and contributor dynamics. We then identified 13 challenges associated with mentoring in OSS, which fall into three categories: social, process, and technical. We also present a quick-reference strategy catalog to map these strategies to challenges for mitigation. Conclusions: Our study serves as a guideline for researchers and practitioners about mentoring challenges and potential strategies to mitigate these challenges.","2024-07","2025-05-05 17:10:02","2025-05-05 17:10:02","","NA","","NA","171","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER","","","","Open source; Mentoring; Literature review","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

While these GDM processes have attracted the attention of researchers, the rationale behind decisions, that is, how decisions are made that enhance the OSS, have not received much attention. This work bridges this gap by extracting these rationales from a large open source repository comprising 1.55 million emails available in Python development archives. This work makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs information retrieval, natural language processing, and heuristics-based techniques. Using these techniques, it extracts the rationale behind specific decisions (for example, whether a new module was added based on core developer consensus or a benevolent dictator's pronouncement). This work unearths 11 such rationales behind decisions in the Python community and thus makes a knowledge contribution. It also analyzes the prevalence of these rationales across all PEPs and three sub-types of PEPs: Process, Informational, and Standard Track PEPs. The effectiveness of our contributions has been positively evaluated using quantitative and qualitative approaches (e.g., comparison against baselines for rationale identification showed up to 47% improvement in the most conservative case, and feedback from the Python steering committee showed the accurate identification of rationales respectively). The approach proposed in this work can be used and extended to discover the rationale behind decisions that remain hidden in communication repositories of other OSS projects, which will make the decision-making (DM) process transparent to stakeholders and encourage decision-makers to be more accountable.","2024-04","2025-05-05 17:10:02","2025-05-05 17:10:02","","NA","","4","36","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The research highlights the highly transient behavior of fast flood flows, particularly when carrying debris, and their effect on bridge superstructures. Utilizing a Digital Elevation Model to extract cross-sectional and elevation data, the research examined 23 profiles over 800 m of the river. The results indicate that the maximum allowable water depth in front of the bridge is 4.73 m, with a Manning's coefficient of 0.03 and a longitudinal slope of 9 m per kilometer. Therefore, a novel method to identify the risks through HEC-RAS modeling significantly improves the conservation of masonry bridges by providing precise topographical and hydrological data for accurate simulations. Moreover, the detailed information obtained from LIDAR and UAV photogrammetry about the bridge's materials and structures can be incorporated into the conservation models. This comprehensive approach ensures that preservation efforts are not only addressing the immediate hydrodynamic threats but are also informed by a thorough understanding of the bridge's structural and material conditions. Understanding rating curves is essential for water management and flood forecasting, with the study confirming a Manning roughness coefficient of 0.03 as suitable for smooth open-channel flows and emphasizing the importance of geomorphological conditions in hydraulic simulation.","2024-08","2025-05-05 17:10:02","2025-05-05 17:10:02","","NA","","16","16","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

To enhance crop yield, environmental regulation techniques have been widely employed in protected production. However, the absence of user-friendly, data-driven tools for developing regulation models remains a challenge. This study aims to propose IPECM, an independent and user-friendly software platform for processing and analyzing crop photosynthetic rate (Pn) data and formulating environmental regulation targets. The platform provides functionalities, such as Pn prediction model development, environmental regulation model development and result visualization, supporting various machine learning algorithms and regulation target obtaining algorithms. The IPECM Platform's application is demonstrated through examples of light intensity regulation for cucumber growth and CO2 concentration regulation for tomato growth. The results showcase the software's ability to handle photosynthetic data of any dimension, with the established Pn prediction model achieving a coefficient of determination of 0.98 and a root mean square error lower than 1 mu mol center dot m(-2)center dot s (-1).

Such SCA tools depend on a vulnerability database to know affected libraries of each vulnerability. However, it is labor-intensive and error prone for a security team to manually maintain the vulnerability database. While several approaches adopt extreme multi-label learning to predict affected libraries for vulnerabilities, they are practically ineffective due to the limited library labels and the unawareness of ecosystems.To address these problems, we first conduct an empirical study to assess the quality of two fields, i.e., affected libraries and their ecosystems, for four vulnerability databases. Our study reveals notable inconsistency and inaccuracy in these two fields. Then, we propose Holmes to identify affected libraries and their ecosystems for vulnerabilities via a learning-to-rank technique. The key idea of Holmes is to gather various evidences about affected libraries and their ecosystems from multiple sources, and learn to rank a pool of libraries based on their relevance to evidences. Our extensive experiments have shown the effectiveness, efficiency and usefulness of Holmes.","2024","2025-05-05 17:10:02","2025-05-05 17:10:02","","NA","","NA","NA","","","","ICSE '24","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9798400702174 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software; affected libraries; vulnerability quality","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Due to this reason, this research focused on the preparation of a biomaterial sheet using natural material and with a low-cost method. Firstly, a silk floss sheet (SFS) was prepared using the waste cocoons by degumming, opening up, and finishing process. Afterward, the biodegradable ss-cyclodextrin (ss-CD) was successfully grafted onto SFS using citric acid (CA) through the pad-dry-cure method. Then, Iranian herbal essential oils (Shirazi thyme and Dermaneh) were loaded into the cavities of ss-CD molecules. Then, the samples were investigated using SEM and elemental analysis. The inclusion complex formed between the herbal essential oils and the ss-CD cavity (HEOs- ss-CD) was also evaluated using high-sensitivity analyses of FTIR, XRD, and UV-Visible. Furthermore, free HEOs and HEOs- ss-CD inclusion complex were assessed for their ability to scavenge the 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) radical, and the results showed that the HEOs- ss-CD inclusion complex can improve antioxidant activity compared to the free HEOs. The antimicrobial activity of the prepared SFS was also determined against Staphylococcus aureus, Escherichia coli, and Candida albicans by quality and quantity methods. The results have shown that the modified SFS has a high resistance against the mentioned microorganisms. In addition, the SFS had no negative effect on the viability of the Vero cell line. It seems that the ss-CD-SFS loaded with essential oils can be a good candidate for biomaterial applications and controlled release systems.","2024-01","2025-05-05 17:10:03","2025-05-05 17:10:03","","83-97","","1","25","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: KOREA SCIENCE TECHNOLOGY CTR #501 635-4 YEOGSAM-DONG, KANGNAM-GU, SEOUL\n 135-703, SOUTH KOREA Publisher: KOREAN FIBER SOC","","","","Antimicrobial; Antioxidant; beta-cyclodextrin; Herbal essential oils; \n Nanostructure","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, low retention of sEVs affects their therapeutic effects. Clinically used natural substitute inorganic bovine bone mineral (Bio-Oss) bone powder lacks high compactibility and efficient osteo-inductivity that limit its clinical application in repairing large bone defects. In this study, a poly ethylene glycol/hyaluronic acid (PEG/HA) hydrogel was used to stabilize Bio-Oss and incorporate rat bone marrow stem cell-derived sEVs (rBMSCs-sEVs) to engineer a PEG/HA-Bio-Oss (PEG/HA-Bio) composite scaffold. Encapsulation and sustained release of sEVs in hydrogel scaffold can enhance the retention of sEVs in targeted area, achieving long-lasting repair effect. Meanwhile, synergistic administration of sEVs and Bio-Oss in cranial defect can improve therapeutic effects. The PEG/HA-Bio composite scaffold showed good mechanical properties and biocompatibility, supporting the growth of rBMSCs. Furthermore, sEVs enhanced in vitro cell proliferation and osteogenic differentiation of rBMSCs. Implantation of sEVs/PEG/HA-Bio in rat cranial defect model promoted in vivo bone regeneration, suggesting the great potential of sEVs/PEG/HA-Bio composite scaffold for bone repair and regeneration.

The combination of information from various modalities can contribute to a comprehensive understanding of tissue specimens, aiding in more accurate diagnoses, and improved research insights. Multimodal image registration in histology samples presents a significant challenge due to the inherent differences in characteristics and the need for tailored optimization algorithms for each modality.ResultsWe developed MMIR a cloud-based system for multimodal histological image registration, which consists of three main modules: a project manager, an algorithm manager, and an image visualization system.ConclusionOur software solution aims to simplify image registration tasks with a user-friendly approach. It facilitates effective algorithm management, responsive web interfaces, supports multi-resolution images, and facilitates batch image registration. Moreover, its adaptable architecture allows for the integration of custom algorithms, ensuring that it aligns with the specific requirements of each modality combination. Beyond image registration, our software enables the conversion of segmented annotations from one modality to another.","2024-03-05","2025-05-05 17:10:04","2025-05-05 17:10:04","","NA","","1","24","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Since then, it has become practically essential for identifying bacteria in microbiological diagnostic laboratories. In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from. MSProfileR has been developed in the R environment and offers a user-friendly web interface using the R Shiny framework. It is available on Microsoft Windows as a web browser application by simple navigation using the link of the package on Github v.3.10.0. MSProfileR is therefore accessible to non-computer specialists and is freely available to the scientific community. We evaluated MSProfileR using two datasets including exclusively MS spectra from arthropods. In addition to coherent sample classification, outlier MS spectra were detected in each dataset confirming the value of MSProfileR.","2024-06","2025-05-05 17:10:04","2025-05-05 17:10:04","","NA","","2","11","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","Github; R package; arthropod vectors; MALDI-TOF MS; quality control; Shiny interface; \n rstudio","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers typically test hypotheses on the controlling torques via forward computer models, which allow accepting or rejecting hypotheses on the basis of the fit of model-output plate velocities to kinematic reconstructions. Such models typically require a significant amount of input information (e.g., tectonic boundaries, structure of the lithosphere, lateral variations of rheology, among others) to appropriately model the tectonic system, and obtain sufficiently-realistic realizations of plate motions. Alternatively, the inverse problem approach takes the difference between the plate torque-balance at two distinct moments in time. This results in an equation in which (a) torques that have not varied through time are canceled out and (b) torques that instead have varied through time are linked to the resulting plate-motion change through a term that accounts for the plate shape and the rheology of the underlying asthenosphere. This approach sacrifices the capability to describe the different individual forces/torques acting upon a plate. Instead, it focuses on determining torque temporal variations, which significantly reduces the amount of input knowledge required. In this technical note we introduce MYRIAM, an open-source software that implements such an inverse approach. MYRIAM takes plate-motion temporal changes, and outputs an estimate of the torque variation required upon a plate to generate the input kinematic change. MYRIAM is released as an open-source repository hosted at GitHub, complete with source code and executable files for Windows and Unix-based operating systems. Plain Language Summary The outermost layer of the Earth, known as the lithosphere, is fragmented into plates that are in motion relative to each other. Through geological history, the motion of tectonic plates did not remain steady, and in fact important changes are now known to have occurred relatively fast, within a few million years. By virtue of Newton's laws of motion, these changes are all necessarily caused by the variation in one or more forces acting upon the plates, and therefore disrupt their force balance. Changing the motion of a plate is not an easy feat-for plates it requires overcoming the frictional resistance exerted by the underlying asthenosphere, a low-viscosity layer beneath the plates. The resulting motion change will depend on (a) the mechanical properties of the asthenosphere and (b) the amount of plate surface interacting with said asthenosphere (i.e., the basal area of the plate). All these considerations are taken into account by MYRIAM, an open-source, computationally-inexpensive software that estimates the force/torque variations required to produce a given change of plate motion.","2024-02","2025-05-05 17:10:04","2025-05-05 17:10:04","","NA","","2","25","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Users on Stack Overflow actively revise posted code snippets, sometimes addressing bugs and vulnerabilities. Accordingly, developers that reuse code from Stack Overflow should treat it like any other evolving code dependency and be vigilant about updates. It is unclear whether developers are doing so, to what extent outdated code snippets from Stack Overflow are present in GitHub projects, and whether developers miss security-relevant updates to reused snippets. To shed light on those questions, we devised a method to 1) detect outdated code snippets versions from 1.5M Stack Overflow snippets in 11,479 popular GitHub projects and 2) detect security-relevant updates to those Stack Overflow code snippets not reflected in those GitHub projects. Our results show that developers did not update dependent code snippets when those evolved on Stack Overflow. We found that 2,405 code snippet versions reused in 2,109 GitHub projects were outdated, with 43 projects missing fixes to bugs and vulnerabilities on Stack Overflow. Those 43 projects containing outdated, insecure snippets were forked on average 1,085 times (max. 16,121), indicating that our results are likely a lower bound for affected code bases. An important insight from our work is that treating Stack Overflow code as purely static code impedes holistic solutions to the problem of copying insecure code from Stack Overflow. Instead, our results suggest that developers need tools that continuously monitor Stack Overflow for security warnings and code fixes for reused code snippets and not only warn during copy-pasting.","2024","2025-05-05 17:10:04","2025-05-05 17:10:04","","1083-1101","","NA","NA","","","","IEEE Symposium on Security and Privacy","","","","","","NA","","","","","","","Backup Publisher: IEEE; IEEE Comp Soc ISBN: 979-8-3503-3131-8; 979-8-3503-3130-1 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

With the aim to investigate the trustworthiness of the Pull Request (PR) process, the common model of collaborative development in OSS community, we exploit process mining to identify and analyze the normal and anomalous patterns of PR processes, and propose our approach to identifying anomalies from both control-flow and semantic aspects, and then to analyze and synthesize the root causes of the identified anomalies. We analyze 17531 PRs of 18 OSS projects on GitHub, extracting 26 root causes of control-flow anomalies and 19 root causes of semantic anomalies. We find that most PRs can hardly contain both semantic anomalies and control-flow anomalies, and the internal custom rules in projects may be the key causes for the identified anomalous PRs. We further discover and analyze the patterns of normal PR processes. We find that PRs in the non-fork model (42%) are far more likely than the fork model (5%) to bypass the review process, indicating a higher potential risk. Besides, we analyzed nine poisoned projects whose PR practices were indeed worse. Given the complex and diverse PR processes in OSS community, the proposed approach can help identify and understand not only anomalous PRs but also normal PRs, which offers early risk indications of suspicious incidents (such as poisoning) to OSS supply chain.","2024","2025-05-05 17:10:04","2025-05-05 17:10:04","","NA","","NA","NA","","","","ICSE '24","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9798400702174 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software development; pull request; process mining","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Constructing simulations to assess the effect of the penetration of distributed generation on electrical distribution networks has become of great importance for Distribution Network Operators (DNOs). This paper proposes a simulation strategy based on open-source platforms and the integration of scripting tools for the rapid modeling of large-scale electrical distribution circuits with distributed renewable generation. The implementation is based on the adaptation of a tool called QGIS2OpenDSS, which creates OpenDSS distribution network models directly from an open-source geographic information system, QGIS. The plugin's capabilities are demonstrated using a real distribution feeder with more than 60% penetration of renewable generation based on photovoltaic systems. These simulations are carried out using real data from a circuit provided by a DNO in the Dominican Republic, which is used to demonstrate how this approach provides a more accessible and flexible way to simulate and assess the effect of Distributed Energy Resources (DERs) in medium voltage (MV) and low voltage (LV) networks, enabling utilities to evaluate system performance and identify potential issues. The integration of this open-source tool within the DNO software stack enables users to apply it according to specific project needs, enhancing their capability to analyze and manage high DER penetration levels, aiding in better planning, operation, and decision-making processes related to renewable energy projects.","2024-06","2025-05-05 17:10:05","2025-05-05 17:10:05","","NA","","12","17","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

However, a more holistic diagnosis of systemic risk in software ecosystem should consider how these social and technical sources of risk interact and amplify one another. Motivated by the observation that the same individuals maintain several libraries within dependency networks, we present a methodological framework to measure risk in software ecosystems as a function of both dependencies and developers. In our models, a library’s chance of failure increases as its developers leave and as its upstream dependencies fail. We apply our method to data from the Rust ecosystem, highlighting several systemically important libraries that are overlooked when only considering technical dependencies.

Our work comprehensively investigates cross-project code clones in open-source software for Internet of Things (IoT) systems across multiple programming languages. This work addresses the prevalence of cross-project code clones in IoT systems and their impact on software maintainability. We collected 122 IoT system repositories in nine languages from GitHub and grouped them according to their primary functionality in IoT systems. We used MSCCD, a multilingual code clone detector to detect Type-3 code clones for each group. The results show that cross-project clones exist in more than 30% of the projects, particularly in communication-related functionalities. We tracked the historical evolution of these clones and classified them according to the revision history and changing trend of similarity. The results show that 95% cross-project clones are untouched. Moreover, clones with decreasing similarities were over 72%. Therefore, the same clone detector may no longer detect these clones. We also investigated whether these cross-project code clones lead to defect propagation by analyzing the commit message to determine the commits that fixed a defect. We identified nine defect propagation instances, of which seven remain unfixed. Our work contributes to understanding cross-project code clones, highlighting the importance of automated clone management tools for improving the quality and security of IoT system software to mitigate the risks associated with unresolved defects and inconsistencies in IoT software development.","2024","2025-05-05 17:10:05","2025-05-05 17:10:05","","179104-179118","","NA","12","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This article introduces the NP3 MS Workflow, a robust open-source software system for liquid chromatography-tandem mass spectrometry (LC-MS/MS) untargeted metabolomic data processing and analysis, designed to rank bioactive natural products directly from complex mixtures of compounds, such as bioactive biota samples. NP3 MS Workflow allows minimal user intervention as well as customization of each step of LC-MS/MS data processing, with diagnostic statistics to allow interpretation and optimization of LC-MS/MS data processing by the user. NP3 MS Workflow adds improved computing of the MS2 spectra in an LC-MS/MS data set and provides tools for automatic [M + H](+) ion deconvolution using fragmentation rules; chemical structural annotation against MS2 databases; and relative quantification of the precursor ions for bioactivity correlation scoring. The software will be presented with case studies and comparisons with equivalent tools currently available.

The controller plays the role of the `brain' that dictates the intelligent part of SDN technology. Various versions of SDN controllers exist as a response to the diverse demands and functions expected of them. There are several SDN controllers available in the open market besides a large number of commercial controllers; some are developed to meet carrier-grade service levels and one of the recent trends in open-source SDN controllers is the Open Network Operating System (ONOS). This paper presents a comparative study between open source SDN controllers, which are known as Network Controller Platform (NOX), Python-based Network Controller (POX), component-based SDN framework (Ryu), Java-based OpenFlow controller (Floodlight), OpenDayLight (ODL) and ONOS. The discussion is further extended into ONOS architecture, as well as, the evolution of ONOS controllers. This article will review use cases based on ONOS controllers in several application deployments. Moreover, the opportunities and challenges of open source SDN controllers will be discussed, exploring carrier- grade ONOS for future real-world deployments, ONOS unique features and identifying the suitable choice of SDN controller for service providers. In addition, we attempt to provide answers to several critical questions relating to the implications of the open-source nature of SDN controllers regarding vendor lock-in, interoperability, and standards compliance, Similarly, real-world use cases of organizations using open-source SDN are highlighted and how the open-source community contributes to the development of SDN controllers. Furthermore, challenges faced by open-source projects, and considerations when choosing an open-source SDN controller are underscored. Then the role of Artificial Intelligence (AI) and Machine Learning (ML) in the evolution of open-source SDN controllers in light of recent research is indicated. In addition, the challenges and limitations associated with deploying open-source SDN controllers in production networks, how can they be mitigated, and finally how open- source SDN controllers handle network security and ensure that network configurations and policies are robust and resilient are presented. Potential opportunities and challenges for future Open SDN deployment are outlined to conclude the article.","2024","2025-05-05 17:10:06","2025-05-05 17:10:06","","747-800","","1","80","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We are dependent on software controlled by global technology giants. The dependence on commonly used services and platforms provided by Microsoft, Google or Amazon must be removed to achieve digital sovereignty. Open-source software has been readily available for a long time, but studies looking into excluding all proprietary software from working life are scarce. This paper investigates the feasibility of replacing proprietary software as a step towards digital sovereignty. The ability to self-host services is key to ensuring independence, and the ability to verify software code is key to ensuring integrity. Therefore open-source code and transparency are transient properties for sovereign software. We present problems by mapping the problematic software used by teachers, researchers and student assistants at Arcada UAS with a varied set of requirements on the digital tools of their daily lives. We research alternatives and deploy a suite of software compatible with EU policies on digital sovereignty. We rely on many services offered by tech giants in our professional lives. There are several open-source software suites that can be self-hosted and that have permissive licenses for business use. Extensive technical knowledge is required for the deployment of software. Most daily tasks can be accomplished by using sovereign software, although not all needs of the test group were met. Companies can deploy sovereign software for most daily tasks, reducing dependency on tech giants. However, software adoption was low. Arcadas IT-support does not host, enforce or endorse the usage of sovereign software. Public code repositories enable independent code verification, in contrast to proprietary software. Some software cannot be easily replaced, and digital habits are hard to change.","2024","2025-05-05 17:10:06","2025-05-05 17:10:06","","106-113","","NA","1027","","","","Lecture Notes in Networks and Systems","","","","","","NA","","","","","","","Backup Publisher: Fac Arcada Univ Appl Sci; Int Assoc Online Engn, Global Online Lab\n Consortium; Phoenix Contact; Int Educ Network; Edunet World Assoc; Air\n France; KLM ISBN: 978-3-031-61890-1; 978-3-031-61891-8 Place: NA Publisher: NA","","","","NA","","Auer, M.

It is demonstrated how FLOSS, in the form of Alternative Mobile Operating Systems (AMOS) including Android open-source custom ROMs or mobile Linux systems, gain traction due to enhanced privacy protection, improved usability through tracker-free software and alternative app stores, and adherence to EU directives on the right to self-repair. As AMOS mature for everyday use, they attract consumers, thereby contributing towards sustainable electronics development. Furthermore, the Fediverse's Application Programming Interfaces (APIs) enable seamless information exchange between instances, allowing for nuanced moderation that safeguards user privacy.

This surge in unmanned aerial vehicles has increased attention towards monitoring tasks in vital areas, such as urban spaces for security, surveillance or Internet of the Things applications. In this sense, we propose an open-source software-in-the-loop approach that integrates the complete navigation experience, accounting for potential wind-related effects, and providing realistic 3D modeling of scenarios encompassing open spaces in city landscapes. Our work introduces a wind perturbation estimation strategy, which models the wind effect as an external force along the Zaxis based on altitude variations from real flights. Validation was conducted using real data flights with a quadrotor aiding the navigation with Ardupilot and QgroundControl as a ground station. To complement the experiments we include a small test with a fixed-wing plane to asses the software-in-the-loop accuracy on larger trajectories. Results demonstrate successful tracking of altitude variations, yielding errors below 10% relative to the home position in experiments with average trajectory lengths of 150 m in two scenarios in Quito. The software-in-the-loop simulation aimed to replicate wind conditions specific to the date and time of real data acquisition, providing a platform to emulate possible improvements and assess UAV performance before deployment in actual missions. This research not only contributes to the optimization of monitoring capabilities but also serves as a valuable tool for assessing UAV missions in diverse and dynamic environments.","2024","2025-05-05 17:10:06","2025-05-05 17:10:06","","1453-1460","","NA","NA","","","","International Conference on Unmanned Aircraft Systems","","","","","","English","","","","","","","Backup Publisher: IEEE ISBN: 979-8-3503-5789-9; 979-8-3503-5788-2 Place: 345 E 47TH ST, NEW YORK, NY 10017 USA Publisher: IEEE","","","","Ardupilot; Gazebo; ROS; Software-in-the-loop; wind perturbation","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Currently, RR estimating instrumentation is specialized and bulky, therefore unsuitable for remote health monitoring. Previously, RR was estimated using proprietary software that extract surface electrocardiogram (ECG) waveform features obtained at several thoracic locations. However, developing a non-proprietary method that uses minimal ECG leads, generally available from mobile cardiac monitors is highly desirable. Here, we introduce an open-source and well-documented Python-based algorithm that estimates RR requiring only single-stream ECG signals. The algorithm was first developed using ECGs from awake, spontaneously breathing adult human subjects. The algorithm-estimated RRs exhibited close linear correlation to the subjects' true RR values demonstrating an R-2 of 0.9092 and root mean square error of 2.2 bpm. The algorithm robustness was then tested using ECGs generated by the ischemic hearts of anesthetized, mechanically ventilated sheep. Although the ECG waveforms during ischemia exhibited severe morphologic changes, the algorithm-determined RRs exhibited high fidelity with a resolution of 1 bpm, an absolute error of 0.07 +/- 0.07 bpm, and a relative error of 0.67 +/- 0.64%. This optimized Python-based RR estimation technique will likely be widely adapted for remote lung function assessment in patients with cardiopulmonary disease.","2024-01-02","2025-05-05 17:10:06","2025-05-05 17:10:06","","NA","","1","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The dynamics of the PTM supply chain remain largely unexplored, signaling a clear need for structured datasets that document not only the metadata but also the subsequent applications of these models. Without such data, the MSR community cannot comprehensively understand the impact of PTM adoption and reuse. This paper presents the PeaTMOSS dataset, which comprises metadata for 281,638 PTMs and detailed snapshots for all PTMs with over 50 monthly downloads (14,296 PTMs), along with 28,575 open-source software repositories from GitHub that utilize these models. Additionally, the dataset includes 44,337 mappings from 15,129 downstream GitHub repositories to the 2,530 PTMs they use. To enhance the dataset's comprehensiveness, we developed prompts for a large language model to automatically extract model metadata, including the model's training datasets, parameters, and evaluation metrics. Our analysis of this dataset provides the first summary statistics for the PTM supply chain, showing the trend of PTM development and common shortcomings of PTM package documentation.

The localization algorithm receives images of the stars from a visible camera and tilt measurements from an inclinometer, derives star locations and a gravity vector, and combines these signals to generate an onboard position determinant. This paper contributes (i) the first open-source planetary global localization algorithm based on stars, (ii) a sensor suite design derived of solely commercial-off-the-shelf (COTS) components, and (iii) an unprecedented physical experiment and characterization from this algorithm on Earth's surface. The resulting position determinant is on average 100km from the testing location, consistent across various time and surface inclines. This result is compared to theoretical performance, state-of-the-art sensor performance, and other global localization methods. This achieved determinant error offers a starting point toward localization improvement with more capable sensors and the incorporation of multiple historical determinants for state estimation.","2024","2025-05-05 17:10:08","2025-05-05 17:10:08","","158-164","","NA","NA","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 979-8-3503-6723-2 Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The online fragment-free mass spectra of moxa floss pyrolysis products were obtained within 300-800degree celsius and characterized as hydrocarbons, nitrogenous and oxygenated compounds. The results indicate that pyrolysis temperature plays a leading role in the lowmolecular-weight product distribution, while the storage year has secondary effects. Controlling the pyrolysis temperature in a lower range (<650degree celsius) can effectively reduce the generation of benzene, toluene and other harmful substances. Aromatics could be released from the break of large molecules with aromatic structures and formed from the aromatization of small unstructured compounds at high temperatures. At the temperature lower than 400 degree celsius, short-year samples exhibit a higher intensity of oxygenated compounds. However, with the increase of storage years, nitrogenous heterocyclics such as pyrrole and pyridine are preferably formed at higher temperatures. In addition, increasing the storage year of moxa floss leads the TG curve to exhibit a lower maximum mass loss rate. These results will enrich the understanding of the storage year effect on the beneficial oxygencontaining components generation and the release of harmful components in the moxa floss pyrolysis.","2024-01","2025-05-05 17:10:08","2025-05-05 17:10:08","","NA","","NA","177","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Furthermore, all necessary diagnostic instruments, such as an oscilloscope, a network analyzer, and a spectrum analyzer, are integrated into our software. Apart from providing a quickly scalable, automatic feedback controller, the lock performance that can be achieved by using PyRPL with imperfect equipment, such as piezoelectric transducers and noisy amplifiers, is better than the one achievable with standard analog controllers due to the higher complexity of implementable filters and possibilities of nonlinear operations in the FPGA. This drastically reduces the cost of added complexity when introducing additional feedback loops to an experiment. The open-source character also distinguishes PyRPL from commercial solutions, as it allows users to customize functionalities at various levels, ranging from the easy integration of PyRPL-based feedback controllers into existing setups to the modification of the FPGA functionality.

In turn, specifying and evaluating OSS quality has become a significant challenge for OSS adoption in organizations that are inclined to use them. Although many OSS quality models have been proposed in the literature, the dynamic and diverse nature of OSS has caused these models to be heterogeneous in terms of structure and content. This has adversely affected the standardization of evaluations and led to the evaluation results obtained from different OSS quality models for the same purpose being incomparable and sometimes unreliable. Therefore, in this study, a meta-model for OSS quality (OSS-QMM), which employs a unified structure from existing quality models and enables the derivation of homogeneous models, has been proposed. For this purpose, a systematic and laborious effort has been spent via a step-based meta-model creation process including review-and-revise iterations. In order to validate the OSS-QMM, case study and expert opinion methods have been applied to answer three research questions (RQs) targeted to investigate practical applicability, results comparability, and effectiveness of using the meta-model. Multiple and embedded case study designs have been employed for evaluating three real ERP systems, and 20 subject matter experts have been interviewed during the validation process. The results of multi-faceted empirical studies have indicated that the OSS-QMM has addressed solving problems in OSS quality evaluation and its adoption with high degrees of confidence.","2024-06","2025-05-05 17:10:09","2025-05-05 17:10:09","","487-541","","2","32","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Software; Case studies; Software quality; Enterprise resource planning; Public domain; Quality assessment; Computers–Software","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

This is in part due to the limitations in robustly and quantitatively analyzing shapes within and between groups in an unbiased and high- throughput manner. Geometric morphometrics (GM) has emerged as a widely employed technique for studying shape variation in biology and evolution. This study presents a comprehensive workflow for conducting geometric morphometric analysis of fish morphology. The step-by-step manual provides detailed instructions for using popular free software, such as the TPS series, MorphoJ, ImageJ, and R, to carry out generalized Procrustes analysis (GPA), principal component analysis (PCA), discriminant function analysis (DFA), canonical variate analysis (CVA), mean shape analysis, and thin plate spline analysis (TPS). The Momocs package in R is specifically utilized for in-depth analysis of fish outlines. In addition, selected functions from the dplyr package are used to assist in the analysis. The full process of fish outline analysis is covered, including extracting outline coordinates, converting and scaling data, defining landmarks, creating data objects, analyzing outline differences, and visualizing results. In conclusion, the current protocol compiles a detailed method for evaluating fish shape variation based on landmarks and outlines. As the field of GM continues to evolve and related software develops rapidly, the limitations associated with morphological analysis of fish are expected to decrease. Interoperable data formats and analytical methods may facilitate the sharing of morphological data and help resolve related scientific problems. The convenience of this protocol allows for fast and effective morphological analysis. Furthermore, this detailed protocol could be adapted to assess image-based differences across a broader range of species or to analyze morphological data of the same species from different origins.","2024-10-20","2025-05-05 17:10:09","2025-05-05 17:10:09","","NA","","20","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted a large, multicenter, prospective, observational study to confirm the REGOMA data in a real-world setting. Patients and methods: The major inclusion criteria were histologically confirmed diagnosis of glioblastoma according to the World Health Organization (WHO) 2016 classification and relapse after radiotherapy with concurrent/adjuvant temozolomide treatment, good performance status [Eastern Cooperative Oncology Group performance status (ECOG PS 0-1)] and good liver function. Regorafenib was administered at the standard dose of 160 mg/day for 3 weeks on/1 week off. Brain magnetic resonance imaging was carried out within 14 days before starting regorafenib and every 8-12 weeks. The primary endpoint was overall survival (OS). The secondary endpoints were progression -free survival (PFS), objective response rate, disease control rate (DCR), safety and health-related quality of life. The Response Assessment in Neuro-Oncology (RANO) criteria were used for response evaluation and Common Terminology Criteria for Adverse Events (CTCAE) version 5 for assessment of adverse events (AEs). Results: From September 2020 to October 2022, 190 patients with recurrent glioblastoma were enrolled from 30 cancer centers in Italy: their median age was 58.5 years [interquartile range (IQR) 53-67 years], 68% were male and 85 (44.7%) were in optimal clinical condition (ECOG PS 0). The number of patients taking steroids at baseline was 113 (60%); the second surgery was carried out in 39 (20.5%). O6-methylguanine-DNA methyltransferase (MGMT) was methylated in 80 patients (50.3%) and 147 (92.4%) of the patients analyzed had isocitrate dehydrogenase (IDH) wild type. The median follow-up period was 20 months (IQR 15.6-25.5 months). The median OS was 7.9 months ([95% confidence interval (CI) 6.5-9.2 months] and the median PFS was 2.6 months (95% CI 2.3-2.9 months). Radiological response was partial response and stable disease in 13 (7.3%) and 26 (14.6%) patients, respectively, with a DCR of 21.9%. The median number of regorafenib cycles per patient was 3 (IQR 2.0-4.0). Grade 3-4 drug-related adverse events were reported in 22.6% of patients. A dose reduction due to AEs was required in 36% of patients. No deaths were considered as treatment-related AEs. Conclusions: This large, real -world observational study showed similar OS with better tolerability of regorafenib in patients with relapsed glioblastoma compared with the REGOMA study.","2024-04","2025-05-05 17:10:09","2025-05-05 17:10:09","","NA","","4","9","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS Publisher: ELSEVIER","","","","glioblastoma; real-world; recurrent; REGOMA; regorafenib","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Sherlock enhances search capabilities by using extra information from images and documents, incorporating this information into an Elasticsearch-powered database to enable content-driven searches. The framework operates through a two-stage process. First, it classifies the incoming data by type, directing images to an object detection model and processing documents for keyword extraction. Then, Elasticsearch catalogs the extracted data, facilitating searches based on content. The effectiveness of our searches is largely dependent on the precision of these models, which we improve by training them on large-scale datasets: the Microsoft COCO Dataset for multimedia content and the SemEval2017 Dataset for text documents.

Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer. Our findings underscore the importance of a balanced approach in OSS project management, harmonizing productivity goals with resilience considerations.","2024","2025-05-05 17:10:09","2025-05-05 17:10:09","","706–709","","NA","NA","","","","WWW '24","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9798400701726 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","causal inference; resilience; online collaboration networks","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These techniques show promise for applications such as structural health monitoring. However, video-based approaches to measuring structural dynamics are not as sensitive as on-contact sensor-based techniques. Furthermore, because video-based techniques involve capturing a 2D perspective projection of the 3D environment, there is an added complication in extracting calibrated quantitative measurements from these systems. In many applications, it would be advantageous to deploy networks, or arrays of imagers for monitoring large-scale infrastructure from different perspectives. Often, computer vision techniques, such as multi-view stereo, benefit from knowledge of the position and orientation of the cameras. Unfortunately, accurately knowing this information can lead to increased setup costs. Furthermore, it is not always clear what arrangement of cameras would be sufficient for any given infrastructure monitoring applications. In addition, the performance of arrays of imagers is affected by factors such as lighting conditions and weather. There may also be significant restrictions on the physical locations where imagers are allowed to be placed. For these reasons, it is advantageous to have tools to aid in the design and development of imager-based sensor networks for structural dynamics applications. In this work, we demonstrate the use of open-source computer graphics software for simulating the behavior of imagers observing dynamic structures. We demonstrate the ability to use these tools to plan the deployment of imager-based sensor networks to rapidly test and develop algorithms and techniques for video-based structural dynamics.","2024","2025-05-05 17:10:09","2025-05-05 17:10:09","","19-26","","NA","NA","","","","Conference Proceedings of the Society for Experimental Mechanics Series","","","","","","NA","","","","","","","Backup Publisher: Soc Expt Mech ISBN: 978-3-031-68903-1; 978-3-031-68901-7; 978-3-031-68900-0 Place: NA Publisher: NA","","","","NA","","DiMaio, D.","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The SAA captures and scores different aspects of human singing ability and melodic memory in the context of item response theory. Taking perspectives from both melodic recall and singing accuracy literature, we present results from two online experiments (N = 247; N = 910). On-the-fly audio transcription is produced via a probabilistic algorithm and scored via latent variable approaches. Measures of the ability to sing long notes indicate a three-dimensional principal components analysis solution representing pitch accuracy, pitch volatility and changes in pitch stability (proportion variance explained: 35%; 33%; 32%). For melody singing, a mixed-effects model uses features of melodic structure (e.g., tonality, melody length) to predict overall sung melodic recall performance via a composite score [R(2)c = .42; R(2)m = .16]. Additionally, two separate mixed-effects models were constructed to explain performance in singing back melodies in a rhythmic [R(2)c = .42; R(2)m = .13] and an arhythmic [R(2)c = .38; R(2)m = .11] condition. Results showed that the yielded SAA melodic scores are significantly associated with previously described measures of singing accuracy, the long note singing accuracy measures, demographic variables, and features of participants' hardware setup. Consequently, we release five R packages which facilitate deploying melodic stimuli online and in laboratory contexts, constructing audio production tests, transcribing audio in the R environment, and deploying the test elements and their supporting models. These are published as open-source, easy to access, and flexible to adapt.","2024-08","2025-05-05 17:10:09","2025-05-05 17:10:09","","4358-4384","","5","56","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The study aims to assist a community of OSS developers in quantifying the product's reliability. This research proposes reliability growth models for OSS by incorporating dynamicity in the debugging process. For this, stochastic differential equation-based analytical models are developed to represent the instantaneous rate of error generation. The fault introduction rate is modeled using exponential and Erlang distribution functions. The empirical applications of the proposed methodology are verified using the real-life failure data of the Open Source Software projects, GNU Network Object Model Environment, and Eclipse. A soft computing technique, Genetic Algorithm, is applied to estimate model parameters. Cross-validation is also performed to examine the forecasting efficacy of the model. The predictive power of the developed models is compared with various benchmark studies. The data analysis is conducted using the R statistical computing software. The results demonstrate the proposed models' efficacy in parameter estimation and predictive performance.

However, if OSS have few contributors and are lacking in maintenance activities, such as bug fixes, are used, it can lead to significant costs and resource allocation due to maintenance discontinuation. Since OSS are developed by a diverse group of contributors, the consistency of their involvement may vary, making continuous support and maintenance unpredictable. Therefore, it is necessary to identify the status of each OSS to avoid increased maintenance costs when selecting OSS for use. To address these issues, we use polynomial regression to predict trends in bug-fixing activities and evaluate the survivability of OSS accordingly. We predict the trend of bug-fixing activities in OSS, using factors such as popularity, number of contributors, and code complexity. A lower trend value indicates more vigorous activity. In this paper, we conduct data collection and extraction, generating model, and model testing and evaluation to predict survivability using these data. After collecting data through various tools, the models of different degrees are generated using K-fold cross-validation. The model with the highest performance is selected based on the RMSE (Root Mean Squared Error) and RSE (Residual Standard Error). Then, the chosen model is employed to predict the survivability of OSS and compare it with actual outcomes. This method is experimented with on OSS used in the KakaoTalk commercial messenger app. As a result, several OSS are predicted to have low survivability, and among them, five are analyzed. It is observed that, in reality, activities such as delayed or discontinued release updates occurred. These findings can support OSS users in selecting OSS for cost-saving purposes and alert OSS administrators to the need for solutions to ensure project survival.","2024-04","2025-05-05 17:10:10","2025-05-05 17:10:10","","NA","","7","14","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","GitHub; open source software; software maintainability; survivability; \n polynomial regression","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

For the OSS projects to stay sustainable, i.e., viable and maintained over time without interruption or weakening, maintenance labor requires an underlying infrastructure to be supported and secured. Aims: Using the construct of human infrastructure, our study aims to investigate how maintenance labor can be supported and secured to enable the creation and maintenance of sustainable OSS projects, viewed from the maintainers’ perspective. Method: In our exploration, we interviewed ten maintainers from nine well-adopted OSS projects. We coded the data in two steps using investigator-triangulation. Results: We constructed a framework of infrastructure design that provide insight for OSS projects in the design of their human infrastructure. The framework specifically highlight the importance of human factors, e.g., securing a work-life balance and proactively managing social pressure, toxicity, and diversity. We also note both differences and overlaps in how the infrastructure needs to support and secure maintenance labor from maintainers and the wider OSS community, respectively. Funding is specifically highlighted as an important enabler for both types of resources. Conclusions: The study contributes to the qualitative understanding of the importance, sensitivity, and risk for depletion of the maintenance labor required to build and maintain healthy OSS projects.

Firstly, an OSS risk propagation relationship graph is constructed, and the Fuzzy Analytic Hierarchy Process (FAHP)-entropy weight method is adopted to allocate weights to the weakness assessment indicators of OSS, thereby improving the accuracy of quantifying OSS propagation risks. Then, on the attack graph, the analysis of threat values to host nodes and the probability of successful attack paths are optimized from three perspectives: vulnerabilities, OSSSC, and hosts. Experimental results demonstrate that this method, by combining open source risk factors and conducting multi-dimensional analysis, can more effectively assess the security threats faced by systems, providing a more accurate basis for security defense.","2024","2025-05-05 17:10:11","2025-05-05 17:10:11","","21-27","","NA","NA","","","","NA","","","","","","English","","","","","","","Backup Publisher: N Minzu Univ; Xidian Univ; Future Univ Hakodate; Chuzhou Univ; Ikueikan\n Univ ISBN: 979-8-3503-7678-4; 979-8-3503-7677-7 Place: 10662 LOS VAQUEROS CIRCLE, PO BOX 3014, LOS ALAMITOS, CA 90720-1264 USA Publisher: IEEE COMPUTER SOC","","","","host status; OSSSC; system security; vulnerability assessment","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We conducted an abductive, computationally intensive study of eight OSS projects, using relational event modeling to analyze 1,169,489 actions covering 93 major software releases. The process of entrainment that we identify involves three task allocation mechanisms: (1) developer -issue inertia, (2) developer contribution frequency, and (3) issue popularity. Our analysis demonstrates that these mechanisms and the phases of the release cycle entrain each other. Before a major release, developers engage in a concentrated mobilization phase, whereby they democratize development activity and increasingly allocate community contributions to the set of issues related to the release. After a major release, the extended cleanup phase garners a greater share of development work from recently highly active developers and dilutes the activity of these developers across a wider range of issues. Our theorizing suggests that major releases constitute important events around which OSS communities self -organize and we characterize how this occurs. Our research contributes to theorizing on organizing in OSS communities by explaining how selforganizing task allocation interacts with release cycles through the mechanism of entrainment. We also contribute to the literature on entrainment by showing how it may unfold in the context of online peer production communities such as OSS.","2024-03","2025-05-05 17:10:11","2025-05-05 17:10:11","","67-94","","1","48","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","Open source software; Computers; Software; Software development; Optimization; Public domain; Resource allocation; Impact fees; Entrainment","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

In many urban areas (or agroecosystems), the practice of illegal waste disposing by commercial activities, by abandoning it in the countryside rather than spending economic resources to ensure correct disposal, is widespread. This causes an accumulation of waste in these areas (which can also be protected natural areas), which are then also set on fire to reduce their volume. Obviously, the repercussions of such actions are many. The burning of waste releases contaminants into the environment such as dioxins, polychlorinated biphenyls and furans, and deposits other elements on the soil, such as heavy metals, which, by leaching and percolating, contaminate water resources such as rivers and aquifers. The main objective is the design and implementation of monitoring programs against specific illicit activities that take into account territorial peculiarities. This advanced approach leverages AI and GIS environments to interpret environmental states, providing an understanding of ongoing phenomena. The methodology used is based on the implementation of mathematical and AI algorithms, integrated into a GIS environment to address even large-scale environmental issues, improving the spatial and temporal precision of the analyses and allowing the customization of monitoring programs in urban and peri-urban environments based on territorial characteristics. The results of the application of the methodology show the percentages of the different types of waste found in the agroecosystems of the study area and the degree of concentration, allowing the identification of similar areas with greater criticality. Subsequently, through network and nearest neighbour analysis, it is possible to start targeted checks.","2024-03","2025-05-05 17:10:11","2025-05-05 17:10:11","","NA","","1","8","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Best practices suggest employing UX Capability Maturity Models (UXCMMs), which often specify an evolutionary plateau toward developing a UX-matured system and quantify organizational UX maturity into maturity levels ranging from no or ad hoc improvement to integrated continuous improvement. Numerous generically developed UXCMMs exist. However, none is created for the FOSS community, and less information is available to support their perfect match. Thus, raise suspicions if they have proper UX maturity influencing factors (UXMIFs) for the FOSS community or measure the right thing. The FOSS community differs from traditional software-developing communities and may have different dynamics and UXMIFs, necessitating unique and new methodologies for their discovery. This study, therefore, aims to identify the FOSS community's UXMIFs and evaluate the community's knowledge of UX maturity-related concepts. Its findings may help future researchers, practitioners, and other FOSS developers to develop UXCMMs exclusive to the FOSS community. The study's design is both qualitative and quantitative. It adopted a systematic literature review, interviews, fuzzy Delphi Method, and thematic analysis to collect and analyze data and present the findings. The study's sample included sixty-two active FOSS projects, fifteen FOSS stakeholders, and twelve UX experts.

These volunteers, commonly referred to as OSS project community, serve as the foundation of the OSS project, fostering its creation and sustenance and providing long-term support. The quality and sustainability of the OSS project is reliant upon the development and structure of the self-governing community. When a business organization plans to acquire an OSS solution, it not only takes into consideration the factors such as reliability, security, and scalability but also attaches significant importance to the likelihood of the OSS project being maintained and supported in the future so that it can rely on it as a stable and secure technology solution. Modern cloud-based software hosting platforms, such as GitHub, offer a range of options for automatically and freely accessing the complete development history of millions of OSS projects. This easy availability of detailed development history has enabled researchers to analyze and draw quantitative and scientific inferences about the quality of an OSS project which generally involves assessing three aspects, namely, software product, development process, and project community. With focus on project community part, a Framework for Assessment and Ranking of OSS Community is being presented in the current research work, following a detailed examination of the largest source code hosting and project collaboration platform, GitHub. Technique for Order of Preference by Similarity to Ideal Solution from Multi-Criteria Decision-Making toolkit has been utilized for assessing the quality of the project community. The framework has been validated by applying it on nine OSS projects and comparing the results with the outcomes obtained through an existing OSS evaluation methodology. The comparative analysis demonstrated that the proposed framework aligns with the aforementioned evaluation methodology while offering an opportunity for in-depth analysis on the dynamics of volunteer communities, which is lacking in previous evaluation methods. These insights can prove valuable for both potential adopters and project maintainers, aiding them in making informed strategic decisions. Framework for Project Community Assessment and Ranking follows a phased approach where first phase involves OSS project identification, second phase defines assessment criteria, in third phase data is fetched, stored and metrics are computed; and the last phase involves final Quality Assessment and Ranking. The framework will aid both corporate entities and individual practitioners in identifying an open source project with a robust volunteer community capable of producing a product of exceptional quality.image","2024-07","2025-05-05 17:10:11","2025-05-05 17:10:11","","NA","","7","36","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 111 RIVER ST, HOBOKEN 07030-5774, NJ USA Publisher: WILEY","","","","open source software; multi-criteria decision-making; project community; \n software quality","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Nonwoven mats with a 1-inch thickness were produced by uniformly arranging milkweed fibers within a mold. Various quantities of fiber were employed to obtain nonwoven mats with a fiber content ranging from 5 to 35 kg/m3. Thermal conductivity and thermal diffusivity were measured across diverse relative humidity levels and temperatures. Simultaneously, milkweed floss samples were exposed to identical environmental conditions to assess the moisture regain and specific heat capacities of the fiber. The specific heat capacity of milkweed and thermal conductivity of the nonwovens exhibited a linear increase with temperature. The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content.

Existing static analysis methods struggle with high false positive rates and are easily thwarted by obfuscation and dynamic code execution techniques. While dynamic analysis approaches offer improvements, they often suffer from capturing non-package behaviors and employing simplistic testing strategies that fail to trigger sophisticated malicious behaviors. To address these challenges, we present OSCAR, a robust dynamic code poisoning detection pipeline for NPM and PyPI ecosystems. OSCAR fully executes packages in a sandbox environment, employs fuzz testing on exported functions and classes, and implements aspect-based behavior monitoring with tailored API hook points. We evaluate OSCAR against six existing tools using a comprehensive benchmark dataset of real-world malicious and benign packages. OSCAR achieves an F1 score of 0.95 in NPM and 0.91 in PyPI, confirming that OSCAR is as effective as the current state-of-the-art technologies. Furthermore, for benign packages exhibiting characteristics typical of malicious packages, OSCAR reduces the false positive rate by an average of 32.06% in NPM (from 34.63% to 2.57%) and 39.87% in PyPI (from 41.10% to 1.23%), compared to other tools, significantly reducing the workload of manual reviews in real-world deployments. In cooperation with Ant Group, a leading financial technology company, we have deployed OSCAR on its NPM and PyPI mirrors since January 2023, identifying 10,404 malicious NPM packages and 1,235 malicious PyPI packages over 18 months. This work not only bridges the gap between academic research and industrial application in code poisoning detection but also provides a robust and practical solution that has been thoroughly tested in a real-world industrial setting.","2024","2025-05-05 17:10:11","2025-05-05 17:10:11","","1990–2001","","NA","NA","","","","ASE '24","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9798400712487 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","NPM; PyPI; malicious code poisoning; OSS supply chain","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Researchers have suggested that the corporatization of FLOSS affords opportunities for creating an inclusive workforce. To understand the potential for firms to increase diversity, we conducted a mixed-methods study of diversity and corporate engagement in FLOSS projects. We integrate the results of a qualitative survey and a big data analysis to understand developer perceptions of corporate engagement and its association with gender and geographic diversity. In the qualitative component, we collected responses from 64 FLOSS contributors to elicit their perspectives on corporate engagement. In the quantitative component, we analyzed GitHub data from 38 projects and 9,990 contributors to investigate differences in participation and diversity based on corporate engagement. We find that contributors vary across dimensions that can inform diversity interventions: stances toward corporations and orientation towards individual/collective benefits. Our results suggest that corporate engagement may limit a project's contributor base and geographic diversity. Yet, organizations subsidizing FLOSS have opportunities to increase access to projects which would benefit diversity. This research serves to identify individual and organizational factors which may harm and help diversity initiatives.","2024-11","2025-05-05 17:10:12","2025-05-05 17:10:12","","NA","","NA","217","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Typically, the vulnerability report contains affected versions of a software. However, despite the validation by security expert who discovers and vendors who review, the affected versions are not always accurate. Especially, the complexity of maintaining its accuracy increases significantly when dealing with multiple versions and their differences. Several advances have been made to identify affected versions. However, they still face limitations. First, some existing approaches identify affected versions based on repository-hosting platforms (i.e., GitHub), but these versions are not always consistent with those in package registries (i.e., Maven). Second, existing approaches fail to distinguish the importance of different vulnerable methods and patched statements in face of vulnerabilities with multiple methods and change hunks.To address these problems, this paper proposes a novel approach, Vision, to accurately identify affected library versions (ALVs) for vulnerabilities. Vision uses library versions from the package registry as inputs. To distinguish the importance of vulnerable methods and patched statements, Vision performs critical method selection and critical statement selection to prioritize important changes and their context. Furthermore, the vulnerability signature is represented by weighted inter-procedural program dependency graphs that incorporate critical methods and statements. Vision determines ALVs based on the similarities between these weighted graphs. Our evaluation demonstrates that Vision outperforms state-of-the-art approaches, achieving a precision of 0.91 and a recall of 0.94. Additionally, our evaluation shows the practical usefulness of Vision in correcting affected versions in existing vulnerability databases.","2024","2025-05-05 17:10:12","2025-05-05 17:10:12","","1447–1459","","NA","NA","","","","ASE '24","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: 9798400712487 Place: New York, NY, USA Publisher: Association for Computing Machinery","","","","open source software; vulnerability quality; affected versions","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The author of the article concludes that the oratorio was recognized as a political composition in large part due to the accompanying circumstances of its creation and premiere, but not based on the original idea and its realisation. The author demonstrate “Das Flog der Medusa” like a example of the protest music as a direction that exposes not only fascism, but also any form of social inequality, violence against the person. The study of the features of choral style of “Das Flog der Medusa” reveals parallels in the textural structure between Henze's oratorio and Nono's works of the 1950s (”La victoire de Guernica”, “Il canto sospeso”, “Intolleranza 1960”). The use of political text resources, the operation of individual syllables and phonemes of a literary text, work with multilingual verbal rows, the active use of diagonal texture - all this brings together the choral works of two contemporaries. At the same time, Henze's composition also reflected the searches in the field of vocal timbre, characteristic of other composers of Darmstadt Summer Course - the use of various modifications of speech singing ( Sprech- gesang ), the latest techniques of vocal articulation (vocal tremolo, prolongation of the anterolingual vibrant). All this together allows us to talk about Henz's oratorio as one of the most peculiar choral compositions of the late 1960s.","2024","2025-05-05 17:10:12","2025-05-05 17:10:12","","23-33","","1","14","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

These digests are stored on a peer-to-peer blockchain, enabling nodes to verify the originality via smart contracts. Additionally, the scheme improves the storage structure, protecting the rights of authors and contributors. Experimental results demonstrate the effectiveness and runtime efficiency of the proposed model in extracting digests for blockchain storage while maintaining verification accuracy.

However, cognitively translating 2D images to surgical settings can be difficult and lead to sub-optimal resections. Lymph node dissection can be challenging due to the inability to locate small metastatic lesions, and their proximity to at-risk organ(s). 3D volume rendered (3D-VR) patient specific images can help to address these challenges. We created patient-specific 3D-VR images using freely available open-source programs. Methods: This study included patients part of the clinical trial NCT04857502. Patients received a PET/CT prior to radioguided surgery. 3D Slicer was used to segment anatomy of interest (organs and tumor lesion(s)). After segmentation, the data was exported as an .OBJ file with an accompanying .MTL file. Manipulation of the .MTL file to restore model properties to the .OBJ file, were completed and both files were uploaded into Autodesk Viewer. Surgeons then received an email link to access the finished 3D-VR model on their smartphone or laptop for peri-operative preparation and/or guidance. Results: The method was used in a series of 14 patients with prostate cancer undergoing pelvic lymph node dissection with PSMA-radioguided robotic surgery using pre-operative PSMA PET/CT images acquired on average 103 +/- 69 days prior to resection. The creation of the 3D-VR models was successfully conducted in all 14 cases. In all cases, the lesions identified on the pre-operative PET/CT imaging 3D-VR models were successfully removed during surgery. Conclusion: We created patient-specific anatomical 3D-VR models that the surgeons can use for pre-surgical planning and intraoperative tumor localization, by applying free, open-source software that could be used in any procedure requiring careful and strategical planning.","2025-04","2025-05-05 17:10:13","2025-05-05 17:10:13","","10-16","","NA","236","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 525 B ST, STE 1900, SAN DIEGO, CA 92101-4495 USA Publisher: ACADEMIC PRESS INC ELSEVIER SCIENCE","","","","3D imaging; 3D volume rendered models; PET/CT; PSMA; Radioguided surgery; Surgical planning; Anatomical\n models; Pelvic lymph node\n dissection","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Urban environments must therefore be at the heart of any global energy transition. Furthermore, land availability is a limiting factor for renewable deployment and rooftop PV thus offers a clear advantage. This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 % of the total electricity consumption of the city and where 50 % of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies. Additionally, this article provides valuable information, such as rooftop usability factors, and an overall reduction factor (CT), useful to extend RPVP assessment to larger areas using constant value methods.","2025-03-15","2025-05-05 17:10:13","2025-05-05 17:10:13","","NA","","NA","331","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: PO BOX 564, 1001 LAUSANNE, SWITZERLAND Publisher: ELSEVIER SCIENCE SA","","","","Open-source software; Energy return on investment (EROI); Photovoltaic potential; Rooftop photovoltaics (RPV); Geographic\n information systems (GIS); Net energy analysis\n (NEA)","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Materials and Methods: Ten STL dental and maxillofacial models were obtained from various imaging technologies, including intraoral scanners, computer-aided design (CAD) software, and cone-beam computed tomography (CBCT), and saved as STL files. ChatGPT was used to generate Python scripts in Blender for mesh simplification and data compression, which were then saved as .py files. The models were regenerated from these scripts in Blender, and their accuracy was assessed using GOM Inspect software, comparing trueness and precision. Statistical analysis, including Kruskal-Wallis and Mann-Whitney tests, was conducted to evaluate differences in file sizes between the original, Python-generated, and regenerated STL files, with statistical analyses performed at a level of significance alpha=0.05. Results: The scripting-based technique was successfully utilized in ChatGPT to generate Python script code for accessing comprehensive data on STL models, utilizing Blender's scripting functionality. This approach enabled the generation, regeneration, and visualization of STL models, resulting in significantly smaller file sizes for both the Python script and regenerated STL files compared to the original STL files (p < 0.001). No significant differences in trueness were observed, with deviations ranging from 0.0 m to 6.8 mu m, and all regenerated STL models demonstrated perfect precision. Additionally, a proportional relationship was noted between the original STL file sizes and processing times. Conclusions: The scripting-based approach proved to be effective in coding, storing, and regenerating STL dental data with reduced file sizes and efficient processing times without compromising the accuracy. Clinical Significance: Various STL dental models of patients can be coded, stored, and regenerated to be used again within efficient processing time without affecting the accuracy.","2025-05","2025-05-05 17:10:13","2025-05-05 17:10:13","","NA","","NA","156","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 125 London Wall, London, ENGLAND Publisher: ELSEVIER SCI LTD","","","","Dentistry; Open-source software; 3d data management; accuracy; Stl file optimization; Blender\n scripting","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Survivability, critical for maintaining project quality and trustworthiness, is closely linked to issue activity, as unresolved issues reflect a decline in maintenance capacity and problem-solving ability. Thus, analyzing issue retention rates provides valuable insights into a project's health. This study evaluates OSS survivability by identifying the features that influence issue activity and analyzing their relationships with survivability. Kaplan-Meier survival analysis is employed to quantify issue activity and visualize trends in unresolved issue rates, providing a measure of project maintenance dynamics. A random forest model is used to examine the relationships between project features-such as popularity metrics, community engagement, code complexity, and project age-and issue retention rates. The results show that stars significantly reduce issue retention rates, with rates dropping from 0.62 to 0.52 as stars increase to 4000, while larger codebases, higher cyclomatic complexity, and older project age are associated with unresolved issue rates, rising by up to 15%. Forks also have a nonlinear impact, initially stabilizing retention rates but increasing unresolved issues as contributions became unmanageable. By identifying these critical factors and quantifying their impacts, this research offers actionable insights for OSS project managers to enhance project survivability and address key maintenance challenges, ensuring sustainable long-term success.","2025-01","2025-05-05 17:10:13","2025-05-05 17:10:13","","NA","","2","15","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND Publisher: MDPI","","","","open source software; survivability; Kaplan-Meier survival function; random forest; \n software maintenance","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

We begin with a set of theory-derived factors related to the propensity to reuse, sample instances of different reuse types, and survey developers to better understand their intentions. Our results indicate that copy-based reuse is common, with many developers being aware of it when writing code. The propensity for a file to be reused varies greatly among languages and between source code and binary files, consistently decreasing over time.

This work introduces Dareplane, a modular and broad technology-agnostic open source software platform for brain-computer interface (BCI) research with an application focus on adaptive deep brain stimulation (aDBS). One difficulty for investigating control approaches for aDBS resides with the complex setups required for aDBS experiments, a challenge Dareplane tries to address. Approach. The key features of the platform are presented and the composition of modules into a full experimental setup is discussed in the context of a Python-based orchestration module. The performance of a typical experimental setup on Dareplane for aDBS is evaluated in three benchtop experiments, covering (a) an easy-to-replicate setup using an Arduino microcontroller, (b) a setup with hardware of an implantable pulse generator, and (c) a setup using an established and CE certified external neurostimulator. The full technical feasibility of the platform in the aDBS context is demonstrated in a first closed-loop session with externalized leads on a patient with Parkinson's disease receiving DBS treatment and further in a non-invasive BCI speller application using code-modulated visual evoked potential (c-VEP). Main results. The platform is implemented and open-source accessible on https://github.com/bsdlab/Dareplane. Benchtop results show that performance of the platform is sufficient for current aDBS latencies, and the platform could successfully be used in the aDBS experiment. The timing-critical c-VEP speller could be successfully implemented on the platform achieving expected information transfer rates. Significance. The Dareplane platform supports aDBS setups, and more generally the research on neurotechnological systems such as BCIs.

Free and open-source software (FOSS) presents a viable solution for facilitating the transfer of digital archives for permanent preservation. Despite the existence of FOSS policy in South Africa, the public sector has yet to fully use it to engage in the development and implementation of products for records management and archive preservation using open-source software. This study aims to explore the ingestion of digital archives into an approved long-term storage system through FOSS in South Africa with the view of developing a framework.Design/methodology/approachThe study adopted a qualitative research approach to collect data through interviews with purposively selected participants (records managers, archivists and IT officials) from national government departments that have implemented records management systems for digital curation of archives, as well as the National Archives and Records Services of South Africa (NARSSA), which regulates archives and records management, and the State Information Technology Agency, which regulates information technology in government.FindingsThe findings of the study suggest that the systematic transfer of digital materials from public entities to NARSSA, as required by statute, has not taken place.Research limitations/implicationsThe study specifically targeted national government departments that have implemented digital archives and records management systems. Consequently, perspectives from departments that have not implemented these solutions were excluded.Originality/valueA framework is proposed for the transfer of digital archives, using interoperable FOSS, from government agencies responsible for records management to NARSSA for archival preservation. This framework, it is hoped, will facilitate infrastructure and skills development in the management of records and preservation of archives through open platforms.","2025-01-02","2025-05-05 17:10:15","2025-05-05 17:10:15","","25-33","","1","44","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

LAMB addresses critical gaps in existing educational AI solutions by providing a framework specifically designed for the unique requirements of the education sector. It introduces novel features, including a modular architecture for seamless integration of AI assistants into existing LMS platforms and an intuitive interface for educators to create custom AI assistants without coding skills. Unlike existing AI tools in education, LAMB provides a comprehensive framework that addresses privacy concerns, ensures alignment with institutional policies, and promotes using authoritative sources. LAMB leverages the capabilities of large language models and associated generative artificial intelligence technologies to create generative intelligent learning assistants that enhance educational experiences by providing personalized learning support based on clear directions and authoritative fonts of information. Key features of LAMB include its modular architecture, which supports prompt engineering, retrieval-augmented generation, and the creation of extensive knowledge bases from diverse educational content, including video sources. The development and deployment of LAMB were iteratively refined using a minimum viable product approach, exemplified by the learning assistant: “Macroeconomics Study Coach,” which effectively integrated lecture transcriptions and other course materials to support student inquiries. Initial validations in various educational settings demonstrate the potential that learning assistants created with LAMB have to enhance teaching methodologies, increase student engagement, and provide personalized learning experiences. The system's usability, scalability, security, and interoperability with existing LMS platforms make it a robust solution for integrating artificial intelligence into educational environments. LAMB's open-source nature encourages collaboration and innovation among educators, researchers, and developers, fostering a community dedicated to advancing the role of artificial intelligence in education.

We consider: the variability of mathematical representation techniques on which the theoretical foundations of formal methods are based; formal methods multidisciplinarity; their capability to serve at a meta-level in providing the semantics of programming languages, specification and modelling languages as well as higher- level and domain-specific formal notations; and, finally, how some of these higher-level and domain-specific notations may be lifted at an interdisciplinary level. Within this historical review, we are inspired by Luis Barbosa's “components as coalgebras” approach in seeing that the duality data-process is underlying all those aspects of formal methods. We also see that such a duality may not only be expressed in universal terms within category theory, but may also be characterised in practical terms and focused applications by two distinct logic paradigms, equational logic for the data and rewriting logic for the process, by two modelling directions, forward process definitions and backward data-driven process transformations, and by the distinction between syntax, defined by the data structures, and semantics, provided by rewrite rules. We use the Maude modelling language to illustrate the application of the data- process duality. In fact, Maude use equational logic to define data types and rewriting logic to express system evolution. Illustrative examples are from the areas of cognitive science and human- computer interaction (HCI). We then define a data-driven model transformation, which we call elaborative mining, , which adopts a backward perspective to recover a behaviour that was observed in real life but was not predicted forward by the original model. Finally, we see how the “open source software bazaar”, which is a metaphor for the apparently chaotic open source development process, offers us a big data context to lift the driving process for model transformation from deterministic to statistical.","2025-01","2025-05-05 17:10:15","2025-05-05 17:10:15","","NA","","NA","142","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

The influence of `digital sovereignty' in the EU's Cybersecurity Strategy on cybersecurity of open-source software","NA","","0267-3649","10.1016/j.clsr.2024.106078","NA","`Digital sovereignty' is the geopolitical mantra of the moment. A key agent of that policy shift, the European Union ('EU') has increasingly embraced `digital sovereignty' as both the ideological foundation and impetus for building its digital future in accordance with `European values and principles,' often driven by and intersecting with cybersecurity concerns as articulated in its 2020 Cybersecurity Strategy for the Digital Decade ('Strategy'). Yet it is impossible to consider cybersecurity without open-source software ('OSS'). Increasingly, the EU, USA and other Governments have recognised that fact in the wake of HeartBleed and Log4j incidents. OSS' decentralised governance and ubiquity, underpinning most software worldwide, may amplify vulnerabilities and adverse effects of cyberattacks, whilst its typically collaborative model of development and innovation often fosters valuable, open cybersecurity solutions. In navigating that policy tightrope of OSS as a double-edged sword for cybersecurity, the EU has adopted `closed' language of `digital sovereignty' that is ostensibly contrary to the `open' nature of OSS. That rhetorical duality is particularly pronounced since the EU described OSS as a tool for realising its `digital sovereignty,' in addition to policy support for `a global, open, interoperable cyberspace' alongside the pursuit of `digital sovereignty.' While there is a epistemic gap in understanding the relationship between the EU's rhetoric of `digital sovereignty' and reality, nascent studies indicate that it has a tangible effect on policy change in multiple digital spheres, generally furthering a degree of `control.' However, that relationship within the OSS cybersecurity context has underexplored and poorly understood, although that policy is a priority for the EU and may bear significant implications for OSS globally. Particularly analyzing the Cyber Resilience Act ('CRA') as key means for implementing the EU's Strategy and its first cybersecurity legislation that would comprehensively engage OSS if adopted by the Council, this article argues that the EU's desire to strengthening cybersecurity in OSS is generally welcome. Yet there is an ostensibly a disjunct between `digital sovereignty' that underpins that legislation and OSS cybersecurity, with too much control of OSS potentially proving counterproductive for EU cybersecurity. This paper illustrates that (i) it is imperative for the EU to address OSS cybersecurity; (ii) yet the lens of digital sovereignty is ostensibly a rough fit for that approach, considering OSS' philosophy and practice; and (iii) based on the CRA, EU's practice of translating `digital sovereignty' into policy change is mixed, leaving uncertain ramifications for OSS cybersecurity in the EU and beyond. On the one hand, it moves towards more `control' at least in determining definitional parameters and power dynamics with novel `stewardship' positions for certain OSS entities. That said, the EU generally seeks to leverage OSS to further their regional embrace of OSS rather than to exclude others. Ultimately, the EU has a valuable leadership opportunity to drive forward solutions to OSS cybersecurity in collaboration with others whilst avoiding fragmentation, keeping doors open in recognising that global challenges demand global solutions. That is in its enlightened self-interest.","2025-04","2025-05-05 17:10:15","2025-05-05 17:10:15","","NA","","NA","56","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Genomic selection (GS) predicts genomic breeding values (GEBV) using dense genetic markers. Single-stage models predict GEBVs from phenotypic observations in one step, fully accounting for the entire variance-covariance structure among genotypes, but face computational challenges. Two-stage models, preferred for their simplicity and efficiency, first calculate adjusted genotypic means accounting for spatial variation within each environment, then use these means to predict GEBVs. However, unweighted (UNW) two-stage models assume independent errors among adjusted means, neglecting correlations among estimation errors. Here, we show that fully-efficient two-stage models perform similarly to UNW models for randomized complete block designs but substantially better for augmented designs. Our simulation studies demonstrate the impact of the fully-efficient methodology on prediction accuracy across different implementations and scenarios. Incorporating non-additive effects and augmented designs significantly improved accuracy, emphasizing the synergy between design and model strategy. Consistent performance requires the estimation error covariance to be incorporated into a random effect (Full_R model) rather than into the residuals. Our results suggest that the fully-efficient methodology, particularly the Full_R model, should be more prevalent, especially as GS increases the appeal of sparse designs. We also provide a comprehensive theoretical background and open-source R code, enhancing understanding and facilitating broader adoption of fully-efficient two-stage models in GS. Here, we offer insights into the practical applications of fully-efficient models and their potential to increase genetic gain, demonstrating a 13.80%\textbackslashdocumentclass[12pt]{minimal} \textbackslashusepackage{amsmath} \textbackslashusepackage{wasysym} \textbackslashusepackage{amsfonts} \textbackslashusepackage{amssymb} \textbackslashusepackage{amsbsy} \textbackslashusepackage{mathrsfs} \textbackslashusepackage{upgreek} \textbackslashsetlength{\textbackslashoddsidemargin}\{-69pt} \textbackslashbegin{document}\\13.80\textbackslash%\\\textbac kslashend{document} improvement after five selection cycles when moving from UNW to Full_R models.","2025-02-04","2025-05-05 17:10:15","2025-05-05 17:10:15","","NA","","1","21","","","","NA","","","","","","NA","","","","","","","Backup Publisher: NA ISBN: NA Place: NA Publisher: NA","","","","NA","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Deep learning frameworks have been proposed to facilitate the development of such software systems, among which, PYTORCH and TENSORFLOW stand out as notable examples. Considerable attention focuses on exploring software engineering practices and addressing diverse technical aspects in developing and deploying deep learning frameworks and software systems. Despite these efforts, little is known about the open source software communities involved in the development of deep learning frameworks. In this article, we perform a comparative investigation into the open source software communities of the two representative deep learning frameworks, PYTORCH and TENSORFLOW. To facilitate the investigation, we compile a dataset of 2,792 and 3,288 code commit authors, along with 9,826 and 19,750 participants engaged in issue events on GITHUB, from the two communities, respectively. With the dataset, we first characterize the structures of the two communities by employing four operationalizations to classify contributors into various roles and inspect the contributions made by common contributors across the two communities. We then conduct a longitudinal analysis to characterize the evolution of the two communities across various releases, in terms of the numbers of contributors with various roles and role transitions among contributors. Finally, we explore the causal effects between community characteristics and the popularity of the two frameworks. We find that the TENSORFLOW community harbors a larger base of contributors, encompassing a higher proportion of core developers and a more extensive cohort of active users compared to the PYTORCH community. In terms of the technical background of the developers, 64.4% and 56.1% developers in the PYTORCH and TENSORFLOW communities are employed by the leading companies of the corresponding open source software projects, Meta and Google, respectively; 25.9% and 21.9% core developers in the PYTORCH and TENSORFLOW communities possess Ph.D. degrees, while 77.2% and 77.7% contribute to other machine learning or deep learning open source projects, respectively. Developers contributing to both communities demonstrate spatial and temporal similarities to some extent in their pull requests across the respective projects. The evolution of contributors with various roles exhibits a consistent upward trend over time in the PYTORCH community. Conversely, a noticeable turning point in the growth of contributors characterizes the evolution of the TENSORFLOW community. Both communities show a statistically significant decreasing trend in the inflow rates of core developers. Furthermore, we observe statistically significant causal effects between the expansion of communities and retention of core developers and the popularity of deep learning frameworks. Based on our findings, we discuss implications, provide recommendations for sustaining open source software communities of deep learning frameworks, and outline directions for future research.","2025-03","2025-05-05 17:10:16","2025-05-05 17:10:16","","NA","","3","34","","","","NA","","","","","","English","","","","","","","Backup Publisher: NA ISBN: NA Place: 1601 Broadway, 10th Floor, NEW YORK, NY USA Publisher: ASSOC COMPUTING MACHINERY","","","","GitHub; community evolution; Deep learning; developer classification","","NA","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""

Within wide limits topography and soil type, texture, and fertility seemed to be of minor importance, although milkweed appeared to grow best on well drained lighter soils of average to high fertility and was never found on poorly drained or highly acid soils. Milkweed appeared to find its most favorable environment on recently abandoned row-crop land and on recently cut-over stump land in situations where a sod of quackgrass or bluegrass had not been established. In Emmet County, probably the most densely infested county in the U. S., milkweed occupied 9.8\\% of the cultivated land, 12\\% of the pasture and abandoned crop land, and 2.5\\% of the hay meadow or mow-land, or an average of 8.4\\% of all cleared land.

Fiber characterization and potential market identification are critical to its development. The most promising commercial use for milkweed floss is as a loose fill for jackets and comforters. The purpose of this research was to evaluate milkweed floss as an insulative fill material and to compare its performance to other insulators. Seven identical jackets were constructed using different fill materials matched on a per unit weight basis. The insulation (clo) values for the jackets were measured using a standing, heated manikin in an environmental chamber. Thickness (loft), compression, resiliency, and hand were also measured. Several performance characteristics were evaluated before and after cleaning. The results show that milkweed floss blended with down has insulative properties similar to down.

During pyrolysis, acetic acid, formic acid and methanol are formed in addition to CO2 and H2O. The data also show that pyrolytic decomposition of the three chemical constituents of milkweed occur without any apparent synergistic interaction. The combustion of milkweed produced CO2 and H2O, as expected, but the removal of the waxy coating from the fibers results in an increased susceptibility to combustion.

Therefore, the original quadratic equation is replaced by x 2 - k(x)y 2 m mod n where k(x) is a non-polynomial function of x and since the Poliard-Schnorr algorithm takes as input value k (to output x and y), it becomes impossible to feed -priori k(x) which is output-dependent.The second signature method takes advantage of the fact that although an attacker can generate valid OSS signatures (solutions {x,y} of x 2 - ky 2 m mod n), he has no control over the internal structure of x and y and in particular, if we restrict the solution space by adding extra conditions on x and y, it becomes very difficult to produce forged solutions that satisfy the new requirements.",NA
+1012,Article,"Ecological compensation of the impacts of a road. Preliminary method for the A50 road link (Eindhoven-Oss, The Netherlands)","After years of efforts to avoid or reduce the impact of infrastructure projects on nature, the principle of ecological compensation has been incorporated in Dutch governmental policy. Ecological compensation aims to recover those ecological functions and natural values that still remain affected after maximum effort has been made to reduce the impact of the intervention (mitigation). The accepted aim of current policy is thus no-net-loss of area and quality by means of mitigative and compensatory measures. As part sf the planning process for construction of a stretch of road in The Netherlands, viz,, the A50 road link in the province of North Brabant, a Nature Compensation Plan (NCP) was required to be drawn up. This work has recently been completed by the Regional Directorate of Public Works and Water Management, the initiator of the intervention. The NCP, initially presented as a Draft Plan, was drawn up by the Regional Directorate using a preliminary method designed by the Centre of Environmental Science of Leiden University for deriving compensatory measures. After an opportunity for public comment, the Draft Plan was revised to form a Final NCP. This article describes, firstly, the preliminary method for deriving ecological compensatory measures. The method starts by quantifying the effects of habitat loss, habitat disturbance (by changes in noise emissions, in the water table and in outdoor recreational patterns), barrier action and fauna casualties. Following mitigation of impacts on nature, compensation for non-mitigable effects focuses successively on area size, derived from the impact on breeding birds, and on area quality, derived from the habitat requirements of the vegetation and fauna groups affected by the road. Guidelines for identifying appropriate locations for compensation are also formulated. Secondly, the compensation method is applied to calculate the mitigative and compensatory measures for the A50 trajectory between Eindhoven and Oss. Thirdly, two comparisons are made: the Draft NCP is compared with the results of the preliminary method, and the Draft and the Final NCP are compared with one another in order to identify the role of the interest groups that played a major role in commenting on the Draft Plan. Finally, realization of the compensatory measures and development of the preliminary method itself are discussed. On the basis of the experience with the A50 case study, a more robust compensation method for road projects is to be developed.",10.1016/S0925-8574(96)00024-9

Complete sequencing is then done on a minimal tiling path of selected subclones, recursively focusing on those at the edges of contigs to facilitate mergers of clones across the entire target. To reduce manual labor, PCR processes have been adapted to prepare sequencing templates throughout the entire operation. The streamlined process can thus lend itself to further automation. The OSS approach is suitable for large-scale genomic sequencing, providing considerable flexibility in the choice of subclones or regions for more or less intensive sequencing. For example, subclones containing contaminating host cell DNA or cloning vector can be recognized and ignored with minimal sequencing effort; regions overlapping a neighboring clone already sequenced need not be redone; and segments containing tandem repeats or long repetitive sequences can be spotted early on and targeted for additional attention.",10.1117/12.274362

+1020,Article,Histological evaluation of Bio-Oss® in a 2-stage sinus floor elevation and implantation procedure,"Deproteinized cancellous bovine bone (Bio-Oss(R)) was placed as a grafting material for sinus floor elevation in the right posterior maxilla. After 6 months of healing, 3 cylindrical titanium-plasma coated implants were inserted. Six months later at the abutment connection, it was realized that 1 of the implants could not be reconstructed due to unfavorable positioning. This implant was removed along with a small portion of the surrounding periimplant tissues. The specimen was processed according to standard techniques for hard tissue histology. In both the grafted area and the previously existing area of the sinus floor the bone was primarily of lamellar structure. Intimate contact between newly formed bone and the particles of the graft was present. No overt signs of resorption of the graft particles were visible. Histomorphometric analysis revealed 63\\% of implant-bone contact in the zone of pre-existing bone, and 73\\% in the grafted zone. The area density of bone amounted to 27\\% in the non-grafted as compared to 28\\% in the grafted area. In conclusion, this case report documented that deproteinized bovine bone, when used as a grafting material for augmentation of the sinus floor, may lead to proper osseointegration of a dental implant.",10.1034/j.1600-0501.1998.090108.x
+1021,Article,Bone reactions to anorganic bovine bone (Bio-Oss) used in sinus augmentation procedures: A histologic long-term report of 20 cases in humans,"Many materials are used for sinus augmentation procedures. Anorganic bovine bone (Bio-Oss) has been reported to be osteoconductive, and no inflammatory responses have been observed with the use of this biomaterial. One of the main questions pertaining to Bio-Oss concerns its biodegradation and substitution by host bone. Some investigators have observed rapid replacement by host bone, while other researchers observed slow resorptive activity or no resorption at all. The aim of the present study was to conduct a long-term histologic analysis of retrieved specimens in humans where Bio-Oss was used in sinus augmentation procedures. Specimens were retrieved from 20 patients after varying peri ods from 6 months to 4 years and were processed to obtain thin ground sections. Bio-Oss particles were surrounded for the most part by mature, compact bone. In some Haversian canals it was possible to observe small capillaries, mesenchymal cells, and osteoblasts in conjunction with new bone. No gaps were present at the interface between the Bio-Oss particles and newly formed bone, in specimens retrieved after 18 months and 4 years, it was also possible to observe the presence of osteoclasts in the process of resorbing the Bio-Oss particles and neighboring newly formed bone. Bio-Oss appears to be highly biocompatible and osteoconductive, is slowly resorbed in humans, and can be used with success as a bone substitute in maxillary sinus augmentation procedures.",NA

Imagine if each square of pavement on the sidewalk had an owner, and pedestrians required a license to step on it. Imagine the negotiations necessary to walk an entire block under this system. That is what writing a program will be like if software patents continue. The sparks of creativity and individualism that have driven the computer revolution will be snuffed out.--Richard Stallman and Simson Garfinkel (1992)This article highlights the vulnerability of the open source software movement to patent infringement lawsuits. With the number of patents on software algorithms predicted to exceed 100,000 this year, it is now virtually impossible to write any computer program, however trivial, that does not violate one or more patents. This paper argues that this situation is not only ludicrous, but it is contrary to any reasonable reading of the Constitution's intentions with respect to the protection of intellectual property. In addition, the patentability of software algorithms stems from the U.S. Supreme Court's failure to grasp one of the most fundamental concepts of computer science. From this error stems a long, dysfunctional chain of legal reasoning and patent policies, the effect of which has been to transform the mental reasoning processes, abstract knowledge, and scientific truths of computing into patentable subject matter. The result poses a potentially catastrophic threat not only to the open source software movement and the emerging industry of electronic commerce, but more fundamentally, to the very existence of the sciences of computing, without which further U.S. technological leadership will be impossible to sustain.[PUBLICATION ABSTRACT]",10.1007/s12130-999-1029-x

+1032,Article,Acid-base surface free energies of solids and the definition of scales in the Good-van Oss-Chaudhury theory,"The overwhelming basicity of all analysed surfaces strongly dependent on the choice of liquid triplet used for contact angle measurements and the negative values sometimes obtained for the square roots of the acid-base parameters can be summarized as the main problems arising from the application of the Good-van Oss-Chaudhury (GvOC) theory to the calculation of Lewis acid-base properties of polymer surfaces from contact angle data. This paper tries to account for these problems, namely: (1) the Lewis base, or electron donor component, is much greater than the Lewis acid or electron-acceptor component because of the reference values for water chosen in the original GvOC theory. A direct comparison of the acidic component with the basic one of the same materials has no meaning. A new reference scale for water which is able to overcome this problem is suggested. For the calculation of acid-base components, a best-fit approach is proposed which does not require any starting information about the liquids or polymers and can yield estimates of the acid-base parameters for both the liquids and the polymers involved; (2) the strong dependence of the value of the acid-base components on the three liquids employed is due to ill-conditioning of the related set of equations, an intrinsic and purely mathematical feature which cannot be completely cured by any realistic improvement in experimental accuracy. To reduce or eliminate the effect, one only needs a proper set of liquids, representative of all kinds of different solvents: (3) the negative coefficients appear as a simple consequence of measurement uncertainty, combined with the possible ill-conditioning of the equation set. We cannot exclude, however, that in some cases they could have a different origin.",10.1163/156856100742546

This involved a total of 15 sinus floor elevation procedures being carried out on 11 patients (average age of 49.6 years) according to the technique described by Tatum (1986). The subantral sinus cavity was augmented using bovine apatite combined with venous blood. After an average healing phase of 6.8 months, trephine burrs were used to take 22 bone biopsies from the augmented sinus region. Then 38 Branemark(R) implants were inserted in both the osteotomies resulting from bone sampling and in regular sites in the augmented posterior maxilla. Histomorphometric analysis of ground sections from the bone biopsies prepared according to the standard method of Donath \\& Breuner (1982) produced an average percentage of newly-formed bone of 14.7\\% (+/-5.0\\%) and a proportion of residual xenogenic bone substitute material of 29.7\\% (+/-7.8\\%). Some 29.1\\% (+/-8.1\\%) of the surface of the Bio-Oss(R) granulate was in direct contact with newly-formed bone. Histologically, newly-developed bone became evident, partly invaginating the particles of apatite and forming bridges in the form of trabeculae between the individual Bio-Oss(R) particles. Despite the absence of osteoclastic activity, the inward growth of bone indicates slow resorption of the xenogenic bone graft material. When the implants were uncovered, after an average healing phase of 6 months, 4 of the 38 implants had become loose. Of these 4 implants, 1 had to be subsequently explanted, while the others remained as ``sleeping implants{''} and were not included in the implants superstructure. Thus, the resulting clinical survival rate, prior to prosthetic loading, was 89.5\\%.",10.1034/j.1600-0501.2000.011003217.x

+1056,InProceedings,Fiber optic sensor system (FOSS) for filament-wound gas cylinders,"Filament-wound composite cylinders are used in the marine and transportation industries for storing breathing gases (SCUBA, firefighter tanks) and gaseous fuels (vehicles). These cylinders offer light weight, corrosion resistance, dimensional stability, and the ability to store more air than equivalent metal tanks. The design methodology currently used for composite tanks, however, cannot yet guarantee their safe operation. Accordingly, the U.S. Department of Transportation (DOT) is unable to issue full certification of filament-wound tanks. Rather, some types of composite pressure tanks currently are manufactured under DOT Exemption, TC Regulation 3FCM. The composite tank industry would benefit by improving the safety of operating these tanks. The interest in developing composite pressure tanks is here and the manufacturing technology is mature. What is needed, however, is a means of insuring that composite tanks are as safe to operate as metal tanks. This will facilitate DOT certification and appeal to consumers. This paper discusses a fiber optic sensor system embedded into the composite shell wall as a structural health monitor. Using a simple, low-cost optical fiber sensor and a modified commercial connector, ``smart{''} tanks can be monitored continuously for structural integrity. The opportunity to provide such continuity in structural health monitoring should have a significant positive impact on obtaining DOT certifications and extending product useful life. This paper presents the results of a design program to develop a new filament-wound composite cylinder containing a fiber-optic sensor system (FOSS). The purpose of FOSS is to monitor the structural integrity of the composite material each time the tank is refilled with pressurized gas. Continuous monitoring for material degradation will be an important factor that determines tank recertification intervals and useful tank life. One of the greatest challenges of this design program has been to develop an optical connector that allows external instrumentation to be ``plugged into{''} the composite wall to read optical signals that correlate with structural health. ``While embedding fiber sensors has become routine, ingress to and egress from the embedded units remain a major stumbling block{''} (Spillman, 1995). A simple modification to a commercial connector is proposed for this application. The design and manufacture of the prototype FOSS cylinder shown in Figure 1 are described in this paper. Connector performance and the overall performance of a prototype Type III tank consisting of an aluminum liner, an E-glass/epoxy filament-wound overwrap, and an embedded FOSS are discussed. Results of a pressure test to assess FOSS performance are presented.",NA

The aim of this study was to compare the gliding capacities of different flosses with major differences in structure and experimental behavior in vivo. Methods: In a clinical, single-blind, crossover study of 27 subjects, the forces necessary for passing all 14 proximal contacts between the first premolars were measured using 2 polytetrafluoroethylene (PTFE)-based flosses, 2 nylon-based flosses, and 1 nylon-based tape. The flosses were fixed in a special holder with strain gauges, which allowed registration of the maximum forces at insertion into and removal from the interdental area. Results: In most contacts, the PTFE flosses needed less force compared to the nylon flosses. The range between the flosses was higher in the mandible compared to the maxilla and increased from the mesially located contacts to the more distally located contacts. The nylon tape required higher forces at insertion for all maxillary contacts. All other flosses proved to be equivalent at these contacts. Conclusions: PTFE flosses are superior to nylon flosses in terms of passing stronger proximal contacts in both directions. Due to gliding differences between different types of floss, the selection of a floss has the potential of compensating intra- and interindividual variation in contact strengths.",10.1902/jop.2001.72.5.672

+1061,Article,Legal implications of open-source software,"The proliferation of computer technology and the advent of the Internet have created many new relationships and problems that raise questions about traditional legal and economic principles. The development of ``open-source{''} or ``free{''} software is an example of this phenomenon. Unlike the traditional producers of computer software - Microsoft for example - open-source software is often developed by computer programmers from all over the world, each submitting contributions to the code, and distributed without charge or for a minimal fee. Open-source software is generally passed from programmer to programmer, with the understanding that improvements may be made, but that the improvements must be distributed freely, without any attempt to ``privatize{''} the program. The existence of such relationships among programmers raise several interesting questions. First, how do large-scale open-source projects come into being? One open-source project, the GNU/Linux operating system, even threatens the market share of Microsoft's operating systems - a feat that calls traditional economic theories on the operation of the firm into question. A more important question is whether the open-source model is sustainable and generalizable. Ultimately, one wonders what role the law will play in the open-source community - a community that seems to operate in the absence of traditional legal principles. In this article, which was introduced at the University of Illinois College of Law Symposium on Intellectual Property Challenges in the Next Century, Professor McGowan addresses these questions. Using the GNU/Linux operating system as a case study, he probes the organization of the open-source community and the philosophies of its leading members in order to understand how traditional firm models, intellectual property, and contract law might apply. Professor McCowan concludes by reviewing recent attempts by courts to impose traditional principles in computer software transaction disputes. Ultimately, it appears that the open-source community cannot be neatly categorized. Although many traditional firm theories - such as the formation of a hierarchy - and legal principles - such as copyright - do apply to the open-source model, these theories and principles are employed in creative ways not previously envisioned.",NA

However, controversy exists regarding the need to cover the lateral osteotomy site with a membrane. Also, the healing period before loading remains undefined when machined-surface implants are placed. Twenty-nine patients showing reduced bone volume in the posterior maxilla had 61 Branemark System implants placed in 30 sinuses augmented with a lateral osteotomy approach. Sinuses grafted with Bio-Oss and covered with a collagen membrane Bio-Gide (M+) received 29 implants, while grafted but uncovered sites (M-) received 32 implants. An immediate procedure was followed to place 41 implants and a staged procedure was used for 20 implants, Abutment connection was made in 2 distinct postoperative periods: 6 to 9 months and over 9 months. The patients were followed for an average of 22.4 months. The survival rate of the implants was dependent on the postoperative healing time and membrane presence. In case of the immediate procedure and in M- sites, when residual bone height was less than 5 mm, more failures occurred when the loading was done at 6 to 9 months than after 9 months. No failures occurred in the M- series when a staged approach was followed. The overall survival rate was 78.1\\% for the M- sites and 93.1\\% for the M+ sites. No failures occurred (0/35) in the control implants placed in adjacent native bone. Implant survival rate was related to the quality of the reconstructed cortical plate and to implant length. The concomitant use of a collagen barrier to cover the osteotomy site, when machined-surface implants were used in sinus grafting, seemed to improve the quality of the graft healing and survival rate of the implants loaded between 6 and 9 months after placement.",NA

+1069,Article,Striking a balance between trust anti control in a virtual organization: a content analysis of open source software case studies,"Many organization theorists have predicted the emergence of the networked or virtual firm as a model for the design of future organizations. Researchers have also emphasized the importance of trust as a necessary condition for ensuring the success of virtual organizations. This paper examines the open source software (OSS) `movement' as an example of a virtual organization and proposes a model that runs contrary to the belief that trust is critical for virtual organizations. Instead, I argue that various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations. Borrowing from the theory of the `McDonaldization' of society, I argue that, given a set of practices to ensure the control, efficiency, predictability and calculability of processes and outcomes in virtual organizations, effective performance may occur in the absence of trust. As support for my argument, I employ content analysis to examine a set of published case studies of OSS projects. My results show that, although that trust is rarely mentioned, ensuring control is an important criterion for effective performance within OSS projects. The case studies feature few references to other dimensions of `McDonaldization' (efficiency, predictability and calculability), however, and I conclude that the OSS movement relies on many other forms of social control and self-control, which are often unacknowledged in OSS projects. Through these implicit forms of control, OSS projects are able to secure the cooperation of the autonomous agents that participate in project teams. I conclude by extrapolating from these case studies to other virtual organizations.",10.1046/j.1365-2575.2001.00108.x

Existing solutions often don't consider about the needs for data security and data privacy. Communication is done without any encryption over insecure networks or with encryption using proprietary solutions, which reduces the data communication possibilities to partners with the same equipment. Our goal was to build a gateway, which offers a transparent solution for secure DICOM-communication in a heterogeneous environment. We developed a PC-based gateway system with DICOM-communication to the in-house network and secure DICOM communication for the communication over the insecure network. One gateway installed at each location is responsible for encryption/decryption. The sender just transfers the image data over the DICOM protocol to the local gateway. The gateway forwards the data to the gateway on the destination site using the secure DICOM protocol, which is part of the DICOM standard. The receiving gateway forwards the image data to the final destination again using the DICOM-Protocol. The gateway is based on Open Source software and runs under several operating systems. Our experience shows a reliable solution, which solves security issues for DICOM communication of image data and integrates seamless into a heterogeneous DICOM environment.",10.1117/12.467013

+1080,Article,Equilibrium selection and public-good provision: The development of open-source software,"Collective-action problems arise in a variety of situations. Open-source software is a recent and important example. Copyright restrictions on open-source projects stipulate that any user may modify the software so long as any resulting innovation is freely available to all. In economic parlance, the innovation is a public good. The economic theory of public-good provision raises a number of important questions. Who contributes to such a project, and who free rides? How might a social planner exploit the interdependence of project components to encourage contributions? Under what conditions will such actions result in successful provision? Using a simple game-theoretic framework and recent results from the study of equilibrium selection, we attempt to answer these questions. Under reasonable assumptions of asymmetry and less than complete information, the most efficient providers will contribute. Contributions can be elicited by `integrating' the provision process when providers are sufficiently optimistic about the success of the project. Otherwise, the social planner may be better off `separating' the components so that individual contributions are independent of each other. The analysis yields recommendations for the leaders of open-source projects and other similar collective-action problems.",10.1093/oxrep/18.4.446

To treat such differences systematically, we propose to classify OSS into three types: Exploration-Oriented, Utility-Oriented, and Service-Oriented. Such a classification can provide guidance on the creation and maintenance of sustainable OSS development and communities.",10.1145/512035.512055

+1102,InProceedings,Sediment sequential risk mitigation at Thea Foss Waterway Superfund Site,"Sequential risk mitigation is a three-phase process designed to: (1) reduce the ecological and human health risks posed by highly contaminated sediments through confinement or capping; (2) reduce the risks associated with moderate levels of pollution on a less urgent schedule and at lower cost; and (3) address areas of limited contamination through a combination of natural attenuation and enhanced natural attenuation. Natural attenuation has as its basis the observation that ecosystem recovery appears to be largely a function of time. Sediment decomposition and the mixing of old sediments by bottom-dwelling organisms contribute to reduced contaminant concentrations. Knowledge of these processes is critical to the development of ecosystem recovery and waste management strategies. To evaluate the applicability of natural attenuation, information should be collected to determine whether surface sediment chemical concentrations will reach cleanup standards within a 10-year period through a combination of natural attenuation and adequate source control. The remedial design for the Thea Foss Waterway Superfund Site in Tacoma, Washington, employs the sequential risk mitigation approach. The EPA has selected a remedy involving natural attenuation (21 acres {[}8.4 hectares]), enhanced natural attenuation (4 acres {[}1.6 hectares]), dredging (650,000 cubic yards {[}494,000 cubic meters]), and capping (30 acres {[}12 hectares]) of this 8,000-foot (2,438-meter)-long waterway.

+1108,Article,"Weichselian sediments at Foss-Eikeland, Jæren (southwest Norway):: sea-level changes and glaciation history","The Jzeren area in southwestern Norway has experienced great changes in sea-levels and sedimentary environments during the Weichselian, and some of these changes are recorded at Foss-Eikeland. Four diamictons interbedded with glaciomarine and glaciofluvial sediments are exposed in a large gravel pit situated above the post-glacial marine limit. The interpretation of these sediments has implications for the history of both the inland ice and the Norwegian Channel Ice Stream. During a Middle Weichselian interstadial, a large glaciofluvial delta prograded into a shallow marine environment along the coast of Jaeren. A minor glacial advance deposited a gravelly journal of Quaternary Science diamicton, and a glaciomarine diamicton was deposited during a following marine transgression. This subsequently was reworked by grounded ice, forming a well-defined boulder pavement. The boulder pavement is followed by glaciomarine clay with a lower, laminated part and an upper part of sandy clay. The laminated clay probably was deposited under sea-ice, whereas more open glaciomarine conditions prevailed during deposition of the upper part. The clay is intersected by clastic dykes protruding from the overlying, late Weichselian till. Preconsolidation values from the marine clay suggest an ice thickness of at least 500 m during the last glacial phase. The large variations in sea-level probably are a combined effect of eustasy and glacio-isostatic changes caused by an inland ice sheet and an ice stream in the Norwegian Channel.

+1114,InProceedings,A study of the method of providing secure network channel among secure OSs,"Many studies have been done on secure operating system using secure kernel that has various access control policies for system security. Secure kernel can protect user or system data from unauthorized and/or illegal accesses by applying various access control policies like DAC, MAC, RBAC, and so on. But, even if secure operating system is running under various access control policies, network traffic among these secure operating systems can be captured and exposed easily by network monitoring tools like packet sniffer if there is no protection policy for network traffic among secure operating systems. For this reason, protection for data within network traffic is as important as protection for data within local system. In this paper, we propose a secure operating system trusted channel, SOSTC, as a prototype of a simple secure network protocol that can protect network traffic among secure operating systems and can transfer security information of the subject. It is significant that SOSTC can be used to extend a security range of secure operating system to the network environment.",NA

+1133,Article,"Open Source software in medical informatics - why, how and what","`Open Source' is a 20-40 year old approach to licensing and distributing software that has recently burst into public view. Against conventional wisdom this approach has been wildly successful in the general software market-probably because the openness lets programmers the world over obtain, critique, use, and build upon the source code without licensing fees. Linux, a UNIX-like operating system, is the best known success. But computer scientists at the University of California, Berkeley began the tradition of software sharing in the mid 1970s with BSD UNIX and distributed the major internet network protocols as source code without a fee. Medical informatics has its own history of Open Source distribution: Massachusetts General's COSTAR and the Veterans Administration's VISTA software have been distributed as source code at no cost for decades. Bioinformatics, our sister field, has embraced the Open Source movement and developed rich libraries of open-source software. Open Source has now gained a tiny foothold in health care (OSCAR GEHR, OpenEMed). Medical informatics researchers and funding agencies should support and nurture this movement. In a world where open-source modules were integrated into operational health care systems, informatics researchers would have real world niches into which they could engraft and test their software inventions. This could produce a burst of innovation that would help solve the many problems of the health care system.

They work voluntarily on a project of their choice; they are not forced to join a particular project just because it needs more developers or the project has a high degree of urgency. Developers work for peer-recognition and self-satisfaction. In the open source community, each and every project has an equal priority. Software designed under open source is not released until the project owner thinks that the software has reached a functional stage. One of the success stories is the Linux operating system. Open Source software is always in an evolutionary stage: it never reaches a final stage. As new requirements emerge the software is enhanced by the user/developers.

+1178,InProceedings,Atmospheric radiance modeling using the Optimal Spectral Sampling (OSS) method,"Optimal Spectral Sampling (OSS) is a new approach to radiative transfer modeling which addresses the need for algorithm speed, accuracy, and flexibility. The OSS technique allows for the rapid calculation of radiance for any class of multispectral, hyperspectral, or ultraspectral sensors at any spectral resolution operating in any region from microwave through UV wavelengths by selecting and appropriately weighting the monochromatic points that contribute over the sensor bandwidth. This allows for the calculation to be performed at a small number of spectral points while retaining the advantages of a monochromatic calculation such as exact treatment of multiple scattering and/or polarization. The OSS method is well suited for remote sensing applications which require extremely fast and accurate radiative transfer calculations: atmospheric compensation, spectral and spatial feature extraction, multi-sensor data fusion, sub-pixel spectral analysis, qualitative and quantitative spectral analysis, sensor design and data assimilation. The OSS was recently awarded a U.S. Patent (\\#6,584,405) and is currently used as part of the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) CrIS, CMIS, and OMPS-IR environmental parameter retrieval algorithms.

In this paper, I intend to examine some of the self-conscious ambiguities of the role-playing narrator of The Mill on the Floss. The use of the male narrator is inseparably bound up with a number of compromises for the woman writer and for the female reader. But being thus `compromised' through vicariously living the experience of the masculine Other also allows the woman writer privileged insight into the complex processes of justification and rationalisation through which the masculine world-view is engendered and sustained in narrative; it allows her imaginatively to work through, and to see through, the tangle of cause and effect relations which are often illegitimately marshalled into support of that view, and to cast ironical and critical light on them.",NA

+1203,Article,Morphometric analysis in geographic information systems: applications of free software GRASS and R,"Development and interpretation of morphometric maps are important tools in studies related to neotectonics and geomorphology; Geographic Information Systems (GIS) allows speed and precision to this process, but applied methodology will vary according to available tools and degree of knowledge of each researcher about involved software. A methodology to integrate GIS and statistics in morphometric analysis is presented for the most usual morphometric parameters-hypsometry, slope, aspect, swath profiles, lineaments and drainage density, surface roughness, isobase and hydraulic gradient. The GIS used was the Geographic Resources Analysis Support System (GRASS-GIS), an open-source project that offers an integrated environment for raster and vector analysis, image processing and maps/graphics creation. Statistical analysis of parameters can be carried out on R, a system for statistical computation and graphics, through an interface with GRASS that allows raster maps and points files to be treated as variables for analysis. The basic element for deriving morphometric maps is the digital elevation model (DEM). It can be interpolated from scattered points or contours, either in raster or vector format; it is also possible to use DEMs from NASA's Shuttle Radar Topographic Mission, with 30 m of ground resolution for the USA and 90 m for other countries. Proposed methodology can be adapted according to necessities and available tools. The use of free and open-source tools guarantees access to everyone, and its increasing popularization opens new development perspectives in this research field. (C) 2004 Elsevier Ltd.

As a consequence open source software is now viewed more favourably than in the past, with increased penetration in all markets. Despite the success of these inroads and the cost savings involved in switching to open source software, proprietary software remains far and away the predominant product of choice.

We examine the criteria that make one item of software more attractive to an organisation and compare and contrast software selection in both the public and private sectors. Ultimately we show that OSS is a competitive alternative to proprietary software and that the criteria on which organisations base their software selection, can be met by OSS products.",NA

+1216,Article,OsiriX: An open-source software for navigating in multidimensional DICOM images,"A multidimensional image navigation and display software was designed for display and interpretation of large sets of multidimensional and multimodality images such as combined PET-CT studies. The software is developed in Objective-C on a Macintosh platform under the MacOS X operating system using the GNUstep development environment. It also benefits from the extremely fast and optimized 3D graphic capabilities of the OpenGL graphic standard widely used for computer games optimized for taking advantage of any hardware graphic accelerator boards available. In the design of the software special attention was given to adapt the user interface to the specific and complex tasks of navigating through large sets of image data. An interactive jog-wheel device widely used in the video and movie industry was implemented to allow users to navigate in the different dimensions of an image set much faster than with a traditional mouse or on-screen cursors and sliders. The program can easily be adapted for very specific tasks that require a limited number of functions, by adding and removing tools from the program's toolbar and avoiding an overwhelming number of unnecessary tools and functions. The processing and image rendering tools of the software are based on the open-source libraries ITK and VTK.

+1218,Article,Resistance as {Motivation} for {Innovation}: {Open} {Source} {Software},"Resistance is frequently viewed as a negative aspect of human interaction. Although resistance manifests itself in numerous ways, resistance to change is frequent when individuals are introduced to new ideas or innovations. This form of resistance can limit forward progress of either an individual or an organization. However, a few papers investigated possible positive roles of resistance in human life. This paper proposes that resistance can be a positive motivator to achieve change. Open source software (OSS) is a technological innovation that is laden with aspects of resistance. One of the initial motivations for the development of open source software was ""psychological reactance"" on the part of a few software developers. Reactance is a limited part of the overall construct of resistance; specifically, resistance caused by external threats to an individual's freedom of choice, which generally manifests itself affectively. This paper looks at the role of resistance as a motivator for technological innovation from the perspective of open source softwre development. It also presents techniques for overcoming resistance to the adoption of open source software. Specific techniques presented are the Alpha and Omega strategies for overcoming resistance. Alpha strategies work by attempting to increase the approach forces towards some goal. Conversely, Omega strategies attempt to decrease the avoidance forces, thereby removing resistance to change. Both techniques are used in the context of open source software development to motivate participants.",10.17705/1CAIS.01336

Furthermore current software development is typically performed in a distributed environment involving many developers. While the use of open-source software may create collaborative communities that enhance overall technology exchange, it does nothing directly to manage change nor does it address the quality of the underlying software. This paper describes a software development process that has proven vital to the success of the widely used open-source toolkits ITK (itk.org) and VTK (vtk.org). This process facilitates cross-platform development, includes automatic documentation generation, integrates continuous testing, and posts the results of the process on publicly accessible web pages. The net result is that a responsive feedback loop is created between the developers in the community and automated processes to measure software quality. With this process software converges towards better software as long as the process is enforced.

They complement committee standardization, can be used in standardization, and are sometimes an alternative to standardization. [PUBLICATION ABSTRACT]",NA
+1224,Article,The `Mill on the Floss': Generic plurality in George Eliot,"George Eliot's The Mill on the Floss is obviously the result of generic interferences, the diegesis borrowing a lot from the traditional family saga, but also from the complex structure of classical tragedy, Eliot's understanding of the direct social consequences of Darwin's theories, and the oblique presence of the supernatural with the final overflowing of the Floss. The Mill on the Floss is thus a novel whose structure is wholly based on the blending of several types and subgenres. The novel itself depends on the combination of several discourses, which enrich each other and obliquely create the conditions of their compatibility. The very end of the novel thus benefits from the melodramatic dimension and tradition it seems to imitate, whereas the novel itself cannot be termed a melodrama. In The Mill on the Floss, each subgenre directly redefines George Eliot's novel and creates the possibility of the blending of different genres and types.",NA

The objective of our work is twofold. First, our research aims to understand and model the dynamics of OSS design that take place in mailing list exchanges. Second, our more long term objective is to develop tools to assist OSS developers to extract and reconstruct design relevant information from previous discussions. We show how quotation practices can be used to locate design relevant data in discussion archives. OSS developers use quotation as a mechanism to maintain the discursive context. To retrace thematic coherence in the online discussions of a major OSS project, Python, we follow how messages are linked through quotation practices. We compare our quotation-based analysis with a more conventional, thread-based analysis of the (reply-to) links between messages. The advantages of a quotation-based analysis over a thread-based analysis are outlined. Our approach provides a means to analyze argumentation and design rationales and promises a novel means to discover design relevant information in the archives of online discussions.

We investigated this issue using a framework derived from innovation adoption theory which was then validated in an organisation which had embarked on a large-scale of adoption of OSS. The framework comprised four macro-factors - external environment, organisational context, technological context and individual factors. We then investigated these factors in a large-scale survey. Overall, the findings suggest a significant penetration of OSS with general deployment in two industry sectors consultancy/sotware house and service/communication - and more limited deployment in government/public sector.

The conclusions from Orbotech experience are that when carefully planned and implemented, software reuse provides the anticipated benefits of cost reduction, improved quality and shorter Time-to-Market. The reuse of OSS may provide even higher benefits than conventional software reuse.

+1254,Article,Ensemble Kalman filter assimilation of Doppler radar data with a compressible nonhydrostatic model: OSS experiments,"A Doppler radar data assimilation system is developed based on an ensemble Kalman filter (EnKF) method and tested with simulated radar data from a supercell storm. As a first implementation, it is assumed that the forward models are perfect and that the radar data are sampled at the analysis grid points. A general purpose nonhydrostatic compressible model is used with the inclusion of complex multiclass ice microphysics. New aspects of this study compared to previous work include the demonstration of the ability of the EnKF method to retrieve multiple microphysical species associated with a multiclass ice microphysics scheme, and to accurately retrieve the wind and thermodynamic variables. Also new are the inclusion of reflectivity observations and the determination of the relative role of the radial velocity and reflectivity data as well as their spatial coverage in recovering the full-flow and cloud fields. In general, the system is able to reestablish the model storm extremely well after a number of assimilation cycles, and best results are obtained when both radial velocity and reflectivity data, including reflectivity information outside of the precipitation regions, are used. Significant positive impact of the reflectivity assimilation is found even though the observation operator involved is nonlinear. The results also show that a compressible model that contains acoustic modes, hence the associated error growth, performs at least as well as an anelastic model used in previous EnKF studies at the cloud scale. Flow-dependent and dynamically consistent background error covariances estimated from the forecast ensemble play a critical role in successful assimilation and retrieval. When the assimilation cycles start from random initial perturbations, better results are obtained when the updating of the fields that are not directly related to radar reflectivity is withheld during the first few cycles. In fact, during the first few cycles, the updating of the variables indirectly related to reflectivity hurts the analysis. This is so because the estimated background covariances are unreliable at this stage of the data assimilation process, which is related to the way the forecast ensemble is initialized. Forecasts of supercell storms starting from the best-assimilated initial conditions are shown to remain very good for at least 2 It.",10.1175/MWR2898.1

Mass-market consumers can be divided between those who are informed about the existence of OSS and those who are uninformed. Since OSS producers have little incentive to advertise, there may be a substantial mass of uniformed consumers, leading to market failures that may justify government intervention. We study three government policies: (a) mandated adoption, whereby the government forces public agencies, schools, and universities to adopt OSS, (b) information provision, whereby the government informs the uninformed users about the existence and the characteristics of OSS, and (c) subsidy, whereby the government makes a payment to consumers if they adopt OSS. We show that mandated adoption and information provision may increase social welfare, but the subsidy always reduces it. When network externalities are added to the model, we show that mandated adoption and information provision may increase social welfare if they help the market to tip towards standardization.",10.1007/s11151-004-7297-4

+1268,Article,"Maxillary sinus augmentation with Bio-Oss® particles:: A light, scanning, and transmission electron microscopy study in man","Biological interactions occurring at the bone-biomaterial interface are critical for long-term clinical success. Bio-Oss (R) is a deproteinized, sterilized bovine bone that has been extensively used in bone regeneration procedures. The aim of the present study was a comparative light, scanning, and electron microscopy evaluation of the interface between Bio-Oss (R) and bone in specimens retrieved after sinus augmentation procedures. Under light microscopy, most of the particles were surrounded by newly formed bone, while in a few cases, at the interface of some particles it was possible to observe marrow spaces and biological fluids. Under scanning electron microscopy, in most cases, the particle perimeter appeared lined by bone that was tightly adherent to the biomaterial surface. Transmission electron microscopy showed that the bone tissue around the biomaterial showed all the phases of the bone healing process. In some areas, randomly organized collagen fibers were present, while in other areas, newly formed compact bone was present. In the first bone lamella collagen fibers contacting the Bio-Oss (R) surface were oriented at 243.73 +/- 7.12 degrees (mean +/- SD), while in the rest of the lamella they were oriented at 288.05 +/- 4.86 degrees (mean +/- SD) with a statistically significant difference of 44.32 degrees (p < 0.001). In the same areas the intensity of gray value was 172.56 +/- 18.15 (mean +/- SD) near the biomaterial surface and 158.71 +/- 21.95 (mean +/- SD) in the other part of the lamella with an unstatistically significant difference of 13.79 (P = 0.071). At the bone-biomaterial interface there was also an electron-dense layer similar to cement lines. This layer had a variable morphology being, in some areas, a thin line, and in other areas, a thick irregular band. The analyses showed that Bio-Oss (R) particles do not interfere with the normal osseous healing process after sinus lift procedures and promote new bone formation. In conclusion, this study serves as a better understanding of the morphollogic characteristics of Bio-Oss (R) and its interaction with the surrounding tissues.

NAICS is the industry classification scheme used by the governments of Canada, Mexico and the United States to carry out their respective economic censuses. NAICS is considered a rational system that uses the underlying economic principle of similar production processes as the basis for its classes. For the Information Sector of the economy, as formulated in NAICS, a key production process is the acquisition and defense of copyright. With open source, copyleft licensing eliminates copyright acquisition and protection as major production processes, suggesting that the open source software industry warrants a separate NAICS category. More importantly, our analysis suggests that NAICS cannot be understood as a taxonomy of objective economic activity but is instead a politically and historically contingent system of data classification.",NA

+1272,InProceedings,OSS functions for flexible charging and billing of mobile services in a federated environment,"The 3G environment is promising a wide range of services with a variety of pricing structures and billing schemes for use over different network operator domains, i.e., a federated environment. A key success factor is to respond to customers' desires to choose the billing scheme that suits their needs, to subscribe to all services as a service package, and to pay for them via a single bill regardless of service type, service location, service providers and network operators. Furthermore, customers may want to choose their services and compose a package dynamically without paying attention to the billing scheme used. The main premise of this paper is that pre-paid and post-paid billing schemes will merge and customers will use services according to their account balance and credits, as opposed to their billing scheme. The requirement on service providers is to use OSS (Operations Support System) functions and the accompanying information model to support diverse pricing and billing schemes, which is a complex task. This paper presents key OSS functions and an information model that tackle this complexity. Challenges are described and requirements are defined. Related efforts are highlighted, and the context surrounding this work is laid out in detail. Finally, individual entities of information model and OSS functions are defined and an example using flow-chart to illustrate interaction of functions is presented.",10.1109/INM.2005.1440844

It is therefore increasingly important to be able to interchange model information between tools - whether in a tool chain, for legacy reasons or because of the natural heterogeneity resulting from distributed development contexts. In this study we consider the current utility of XMI interchange for supporting OSS tool adoption to complement other tools in an embedded systems development context. We find that the current state of play is disappointing, and speculate that the problem lies both with the open standards and the way in which they are being supported and interpreted. There is a challenge here for the OSS community to take a lead as tool vendors gear up for XMI 2.0.",10.1145/1083258.1083267
+1275,InProceedings,OSS: A Spatial Decision Support System for Optimal Zoning of Marine Protected Areas,"We have developed the Optimisation Support System (OSS), a spatial decision support system, to deliver optimal solutions to the problem of identifying comprehensive, adequate and representative locations for conservation planning. The South Australian Government is committed to establishing a comprehensive, adequate and representative system of 19 marine protected areas (MPAs) by 2010. Each MPA will be the target for detailed investigations into its biophysical, ecological, social, economic and cultural assets. The aim is to use this information to delineate each MPA into a series of zones that offer various levels of protection and use. At the highest level all marine use and extraction activities will be excluded to allow maximum protection of species diversity and habitat. Community consultation and collaboration is therefore critical for successful MPA establishment. A demand exists for the development of a process that allows public participation within a conservation planning environment. The concept of excluding certain activities, including recreational fishing, has generated much interest in the local media. Recent headlines such as `Calls to Shelve Marine Parks', `Anglers Fight For Future of Jetty Fishing' and `330+ Submissions on MPA Proposal' demonstrate the importance of open consultation and the need to provide an inclusive and transparent decision-making process for the design of MPAs. A decision support tool can facilitate decision-making within a negotiating and conflict resolution environment. We have collated and processed a large database of spatial layers describing the biophysical and human-use features of the marine environment. The biophysical data was then used to identify surrogate ecological regions within the Encounter Pilot MPA. The datasets were categorised into classes describing bathymetry, sea surface temperature, chlorophyll `a' concentration levels, benthic and coastal habitat types, and shoreline exposure and type. Locations that most efficiently represent these surrogates of biodiversity were selected using a common mathematical integer programming optimisation algorithm. Established conservation planning principles underpin this research. Inputs into OSS are a suite of environmental, social, cultural and economic datasets. Optimal solutions are found using integer programming algorithms. Implementation is within a Geographic Information System environment (ESRI's ArcGIS) and third-party commercial software (ILOG's CPLEX) provides the optimisation engine. The user interface of OSS can be accessed through a toolbar button and comprises a series of input modules. Fields are quick and easy to populate and in many cases are read directly from an ArcGIS map document Table of Contents. Solutions are found in less than 1 minute when using datasets described in this paper OSSThis paper briefly demonstrates the application of systematic conservation planning to optimal MPA design and the development of OSS, and explores options for public participation. We demonstrate how OSS and systematic conservation planning can be taken to the wider community to produce on-the-fly outputs. Our novel approach has the potential to build partnerships with community groups and give the community a sense of ownership in the decision-making process. It is more likely that conflicts will be minimised and negotiation hastened for a better MPA zoning outcome for all.",NA

OSS and its development projects differ from proprietary software and closed source projects in several aspects. Therefore, these aspects should be known and analyzed, before making a decision for using OSS in a software development project. This paper analyses various OSS usage strategies in the context of software development projects. Dependent on cases of usage, different open source project collaboration models, based on business process models, are analyzed from several relevant aspects.",NA
+1280,Article,Open Source Software implementation in the UK public sector: Evidence from the field and implications for the future,"Open Source Software (OSS) is a model of computer software development where the source code is available for programmers to view, read, modify and re-distribute without the property right restrictions of proprietary software. OSS has existed as a model for developing computer applications and software since the 1950s. However, OSS has only found its way into the public arena within the past decade due to some major projects gaining significant market share from commercial developers such as Microsoft. Research in the area of OSS has become more extensive in recent years and has examined areas such as motivation of programmers as well as the benefits of OSS. However, literature focusing on the actual implementation of OSS is more limited with only Fitzgerald and Kenny {[}(2004). Developing an information infrastructure with Open Source Software. IEEE Software, 50-55] providing any substantial analysis of how it might be achieved. In this paper the focus is on OSS use and implementation within the UK public sector. This sector has a history of resource wastage and underperforming information systems. The underpinning issues of motivation and benefits to organisations will be addressed along with the difficulties that the UK Government faces in adopting an OSS strategy. Section 2 examines the existing literature in the area and explores why OSS should be adopted and implemented by the public sector in the UK. Section 3 considers the research approach taken and the results obtained from considering the implementation of OSS in eight government organisations. Section 4 concludes with a discussion and some implications for those organisations in the public sector who might wish to take this approach.

+1283,Article,Open source software for medical image processing and visualization,"Societies often create smaller subsets or communities that connect with one another for commerce and intellectual exchange over mutual interests. In science and engineering, the need for communication among researchers is often hampered by artificial barriers of university politics, economic market forces, and the sheer momentum of an academic reward structure that values individual discovery over joint development. Recent initiatives have attempted to reduce some of these barriers, encouraging collaborative multidisciplinary research programs. Through this effort, the processes have been studied that lead to the successful foundation of new communities. The current focus has led to the creation of Insight, a project for open source image processing software development, along with the Insight Software Consortium, which includes more than 17 participating universities and commercial institutions. The initial emphasis of this effort is to provide public software tools for 3D segmentation and deformable and rigid registration, capable of analyzing the head and neck anatomy of the Visible Human Project data. The eventual goal is to provide the cornerstone of a self-sustaining software community in 3D, 4D, and higher dimensional data analysis.

However, the evaluation of its success is limited to histological analysis, and its effects on mechanical hardness remain to be investigated. This study investigated mechanical strength in support of histological findings, specifically for tissue-engineered bone with mesenchymal stem cells (MSCs) and platelet-rich-plasma (PRP). Initially, teeth were extracted, and bone defects on both sides of the mandible were prepared with a trephine bar. The defects were implanted by using the following graft materials: 1) PRP, 2) PRP and dog MSCs (dMSCs), 3) autogenous bone (PCBM), 4) bone substitute (Bio-Oss (R)), and 5) control (defects only). After 2, 4, 8, and 12 weeks of implantation, the defects were histologically assessed to examine their mechanical properties. According to histological observations, the dMSCs/PRP groups had well-formed mature bone compared with the control (defects only), Bio-Oss (R), and PRP groups. The Vickers hardness test values were 8 (control), 9 (PRP), not detected (Bio-Oss (R)), 11 (PCBM), and 17 (dMSCs/PRP) after 2 weeks. Therefore, tissue-engineered bone can be used for early stage bone regeneration from the viewpoint of histology and mechanical properties. (c) 2005 Wiley Periodicals, Inc.",10.1002/jbm.a.30248
+1288,Article,Policy-based model-driven engineering of pervasive services and the associated OSS,"This paper presents our work towards a fully functioning platform for pervasive service engineering in an operational support services (OSS) context for an ICT service provider. The focus of the paper lies in a proof-of-concept for a novel means to develop and execute pervasive services, with simplicity and maintainability as prime drivers. The essence of this approach is the novel integration of the policy-based management (PBM) techniques and the model-driven architecture (MDA) techniques for specifying pervasive services and their behaviour, together with auto-generation of middleware implementation and policy enablement. The presence of policies provides pervasive services with the high flexibility and adaptability needed for dealing with changing environments and resource availabilities, while the introduction of MDA for defining pervasive service information models fundamentally solves the information modelling puzzle of current policy-based approaches. Additionally, MDA's middleware-neutral feature benefits the smooth evolution of pervasive services as a piece of software artefact in the face of heterogeneous devices and platforms. A preliminary case study has demonstrated the practical feasibility and benefits of this approach. The case study revolves around an ICT service called TEANU - transparent enterprise access for nomadic user. The service provides a means for nomadic users to maintain a secure access to their enterprise network in the presence of multiple access network providers with different service level guarantees.",10.1007/s10550-005-0039-9

A particular feature of OSS is that important resources are not directly controlled by firms, but partly reside within communities that co-exist with the firms. Despite this, firms explicitly try to utilize the resources within these communities in order to create and appropriate value. Consequently, the relationships that firms have to these communities influence their way of doing business. Based on case studies of Nordic OSS firms, a typology consisting of symbiotic, commensalistic, and parasitic approaches to handle the firm-community relationship is developed. Depending on the chosen approach, firms encounter different managerial issues and also use different operational means of subtle control. While firms relying on a symbiotic approach have greater possibility to influence the community through subtle means of control, they are also confronted with more challenging managerial issues.

The concept itself is founded on the paradoxical premise that software source code-the 'crown jewels' for many proprietary software companies-should be provided freely to anyone who wishes to see it. Given this fundamental initial paradox, it is perhaps hardly surprising that the OSS concept is characterised by contradictions, paradoxes and tensions throughout. In this paper we focus specifically on the following issues in relation to OSS: the cathedral v. bazaar development approach; collectivism v. individualism, the bitter strife within the OSS community itself (OSS v. OSS), and between OSS and the Free Software Foundation (OSS v. FSF); whether OSS represents a paradigm shift in the software industry; whether the software is truly open-the Berkeley Conundrum, as we have termed it here; whether OSS truly is high quality software; and whether OSS is a 'one size fits all,' representing the future model for all software development.",10.1109/HICSS.2005.609

There are continuing debates over the future of software and, in particular, the competition between OSS and proprietary software. Many studies by governments and by information technology analysts suggest that OSS and open standards are intimately connected and that the inherent value of open-source adoption may be attributable in large part to the embodiment of open standards in OSS. The government environment is changing rapidly in areas as diverse as homeland security and social services. Given the equally rapid changes in the information technology marketplace, the successful adoption of these new technologies by governments will depend on how well the strengths of proprietary software and OSS are understood and applied-especially with respect to the use of open standards to speed deployments of integrated capabilities that respond to emerging challenges. This paper evaluates the relative strengths of proprietary software and OSS as development techniques that embrace the open standards valued by governments.",10.1147/sj.442.0227

Instead of a monolithic master system, small tools with a limited set of tasks are interconnected using standardized, self-descriptive data structures. This approach is highly flexible with respect to the rapidly changing needs of the scientists: Since the modules are isolated and intermodule communication is standardized, new components can be integrated without side effects. The developed software environment follows to a large extent the UNIX design philosophy and is heavily based on open-source software technologies that are used to solve specific tasks within the overall system to achieve high productivity in using the software for ambitious high-throughput experimentation programs. It is shown that the orchestration of the system significantly benefits from clear and standardized interface design based on hteML, the high-throughput experimentation markup language, an XML language for the description of high-throughput experimentation data and processes.

The lion's share of the existing literature on OSS examines communities, that is, those individuals whom are already part of the OSS community. In contrast, this paper starts from users with the requisite skill to use and develop OSS. This group of skilled individuals could potentially invest into the development of OSS knowledge, but they may or may not do so in actuality. This paper, therefore, explores three issues, which have not been extensively explored in the literature, namely, (1) how frequently a group of skilled people use OSS, (2) reasons for differences among users and non-users in terms of use and attitudes, and (3) how frequently, and why, some users contribute to OSS projects (and thereby become developers). In doing so, we consider the opportunity costs of use and development of OSS, which has been largely neglected in the literature. We find that the individuals have a rather pragmatic attitude to firms and that many are active in both firms and OSS community, which raises many questions for future research about the role and influence of firms on the development and diffusion of OSS.",10.1080/1043859052000344705

+1326,InProceedings,An Overlay Server System (OSS) Platform for Multiplayer Online Games over Mobile Networks,"We propose a gaming architecture, called the Overlay Server System (OSS), for supporting multiparty online games over mobile networks. In OSS architecture, overlay server nodes (OSN) are distributed across the core network architecture of the mobile operator and each node is responsible for both running the game applications and performing the overlay routing. The architecture allows third party game servers that are located outside the core network of the mobile operator to push the execution of delay and bandwidth constrained game components into the core to achieve better quality of service (QoS). When a game consists of multiple mutually exclusive game objects such that each object can be maintained independently, OSS allows per object QoS optimization via selecting the jointly optimal location (i.e. OSN) and overlay routes for each object. This fine-grain optimization benefits most when different objects have different QoS requirements and they are accessed by different users. OSS dynamically adapts to the changes in game and network conditions by switching to better OSN and overlay routes. Our performance analysis on different core network topologies and usage patterns demonstrates that OSS has significant advantages over the alternative peer to peer (P2P), proxy-server, and client-server architectures. The analysis also underlines the individual contributions of object placement and jointly performed overlay route optimization to the performance gain.",NA

In this paper, we observes how implementing FLOSS in an Italian high school challenges the conventional relationship between end users themselves (e.g. teachers and students) and that between users and developers. The findings will shed some light on the social aspects of FLOSS-based computerization -- including the roles of FLOSS in social and organizational change in educational environments and the ways that the social organization of FLOSS are influenced by social forces and social practices.",NA

Evidence shows that OSS fails in many cases to displace dominant market leaders even in the case of user's unhappiness with the prevalent solution, while in some others OSS is adopted without a clear advantage. Using a qualitative research approach, we highlight the existence of a new context, in which the adoption of Linux-based OSS platforms by companies is not led only by traditional drivers. User communities and broader social responsibility considerations have been found to exert some degrees of pressure on the IT decision maker. Through the analysis of some significant cases we propose a framework that helps to depict under which conditions significant OSS adoption may unfold.",NA

Refactoring refers to the restructuring of software according to specific mechanics and principles. In this paper, we describe an analysis of the results from a tool whose purpose was to identify and extract refactorings from seven open-source Java systems. In particular, we analyzed the mechanics of the most commonly and least commonly applied refactorings to try and account for their frequency. Results showed the most common refactorings of the fifteen coined a 'Gang of Six', to be generally those with a high in-degree and low out-degree when mapped on a dependency graph; the same refactorings also featured strongly in the remedying of bad code smells. Remarkably and surprisingly, inheritance and encapsulationbased refactorings were found to have been applied relatively infrequently - we offer explanations for why this may be the case. The paper thus identifies 'core' refactorings central to many of the changes made by developers on open-source systems. While we can not guarantee that developers consciously undertake refactoring in any sense, the empirical results demonstrate that simple renaming and moving fields/methods between classes are common components of open-source system re-engineering. From a wider software engineering perspective, knowledge of what a modification will incur in likely sub-tasks is of value to developers whether working on open-source or other forms of software.",10.1145/1159733.1159777

Being able to identify the core members of a FLOSS development project is important because many of the processes necessary for successful projects likely involve core members differently than peripheral members, so analyses that mix the two groups will likely yield invalid results. We compare 3 analysis approaches to identify the core: the named list of developers, a Bradford's law analysis that takes as the core the most frequent contributors and a social network analysis of the interaction pattern that identifies the core in a core-and-periphery structure. We apply these measures to the interactions around bug fixing for 116 SourceForge projects. The 3 techniques identify different individuals as core members; examination of which individuals are identified leads to suggestions for refining the measures. All 3 measures though suggest that the core of FLOSS projects is a small fraction of the total number of contributors.",10.1109/HICSS.2006.101

In addition to an appropriate software budget, activities such as installing security software, setting up user accounts, and configuring lab systems can require significant time and labor resources. In a conventional environment, it may also require a dedicated computer lab for each security class. In a given educational environment, obtaining these resources may be problematic.To mitigate these problems, we developed a ""hand on"" security design process that utilizes Live CDs and Open Source tools.

+1355,Article,Free and open-source software: {Opening} and democratising e- government's black box,"This article considers the implications that the use of free and open-source software in government might have for democracy and public participation. From a constructionist perspective, the democratic effects of non-proprietary software are contingent on how the practice of free and open-source software is discursively represented and constituted as it is translated into new e-government systems. On these premises, an analysis of official discourse and government policy for non-proprietary software suggests that its introduction into government will bring more politics as usual rather than democratisation. Nevertheless, on the basis of an alternative discourse of ethics and freedom evident in the Free Software and Open Source communities, the authors of this paper envisage circumstances in which the discourse and practice of non-proprietary software contribute to opening-up and democratising e-government, by protecting and extending transparency and accountability in e-governments and by offering scope for technology to be shaped by citizens and associations as well as by administrators and private interests.

One could argue that Free Software Foundation is using copyright to enforce their free software licenses as aggressively as the Business Software Alliance is enforcing its clients' copyrights. We will show that the reality is more complex and that there is a significant difference: the free software community uses primarily non-legal enforcement methods and trusts on social norms. We argue that free software could be used as a tool to make copyright more accepted in the less developed world because of its positive connection with copyright and community based approach. We explain why strong copyright is also in the interest of free software developers. The article concludes by suggesting that World Intellectual Property Organization should include free software into its development agenda.[PUBLICATION ABSTRACT],10.1007/s12130-006-1006-6

+1358,Article,Freedom as in a Self-sustainable Community: the Free Software Movement and its challenge to copyright law,"Copyright law, together with the market logic it carries, penetrates deeply into our daily life. The copyright regime is so restrictive that it turns a normal learning process into a series of potential copyright violations. The Free Software Movement (FSM) represents a substantial community effort to counter this trend. It seeks to supersede the copyright regime by offering the `Copyleft' licensing mode, which facilitates the formation of a cooperative, resource- sharing community. The FSM has been so successful that it has challenged the utilitarian values presumed in copyright law, has fuelled widespread reassessment of copyright law, and has influenced many who engage in various creative activities. Claiming to bear similar values, Creative Commons (CC) provides licensing models for people to waive some rights granted to them. However, CC differs from the FSM in significant ways. Most notably, the flexible CC licensing model weakens the firm philosophical and political ground which binds FSM advocates together. Hence, although CC's rapid growth seems to signal its success, it is questionable whether such success is as enduring as the FSM's, or if it is leading to a different result. While CC champions the author's freedom to decide how to use his or her bundle of property rights granted by copyright law, the FSM advocates the freedom to build and live in an alternative, vital and self- sustaining community. The existence of such an alternative model not only allows these particular participants to be independent from the proprietary world, but also may empower the rest of society to imagine different kinds of relationships between human beings and their creative activities.",10.2304/pfie.2006.4.4.337

This study demonstrates both the benefits and the risks of government policy favoring FLOSS from the perspective of economics, technology, and politics, and to further analyze whether these same policy goals can be achieved through government support of FLOSS. The most fundamental argument of the study is that, in lending its support to FLOSS, the difference between a government user and a business user is that the government should take into account society's long-term interests, not merely its own interests as a consumer.[PUBLICATION ABSTRACT]",10.1007/s12130-006-1007-5

We conducted social network analyses of bug-fixing interactions from three repositories: Sourceforge, GNU Savannah and Apache Bugzilla. We find that some OSS teams are highly centralized, but contrary to expectation, others are not. Projects are mostly quite hierarchical on four measures of hierarchy, consistent with past research but contrary to the naive image of these projects. Furthermore, we find that the level of centralization is negatively correlated with project size, suggesting that larger projects become more modular, or possibly that becoming more modular is a key to growth. The paper makes a further methodological contribution by identifying appropriate analysis approaches for interaction data. We conclude by sketching directions for future research.[PUBLICATION ABSTRACT]",10.1007/s12130-006-1004-8

Recent surveys show that the skills of IT staff in an organization are one of the key factors in OSS adoption decisions. This paper develops a model where users choosing between proprietary software and OSS are heterogeneous in their expertise. The paper finds that as users become more skilled in OSS, the price of proprietary software will decline. Second, the equilibrium market structure is influenced by both users' expertise and network effects. It is not surprising that proprietary software can drive OSS out of the market in presence of network effect, but counter-intuitively, this happens when users are highly skilled in OSS. Third, in presence of network effect, OSS may survive in the market only when it is customizable by skilled users and therefore provides significant higher benefits to users than proprietary software.",10.1109/HICSS.2006.213

Some countries have successfully created extensive information technology infrastructures, yet software use continues to be reliant on pirated sources. The experiences of licensing regulation violations and increasing virus attacks indicate that part of the problem is a consequence of dependencies created by the use of proprietary software within resourcescarce economies. Recent growth in the use of free and open-source software (FOSS) by various public-and private-sector agencies suggests an alternative path to software self-suffciency for a resource-scarce country like Cuba. There is, however, an interesting background to current software use within Cuba that makes it unique among several less-developed countries. Apart from the well-known advantages, FOSS use could be essential to shape the future scenario of Cuba. The present paper first delineates some of the Cuban background, basically characterized by lack of freedom in technology ownership and access to external information. The potential of FOSS use within existing conditions in Cuba is then analyzed. Finally, conclusions are provided on the basis of a survey carried out in Cuba, arguing that there needs to be stronger political will to reduce gaps between goals and implementation reality to achieve intrinsic advantages of FOSS use successfully.",10.1162/itid.2006.3.1.1

One way to achieve these ends is to implement eGovernment using free or open source software (FOSS). This will reduce dependence on software owned by major companies in developed countries. It could also promote an IP generating capacity in developing countries. An examination of the status of free or open source software in developing countries in Southeast Asia reveals that governments in these countries are aware of FOSS and wish to foster its use (but face considerable pressure to use proprietary software). This examination also reveals the presence of small but active groups seeking to develop and promote the use of free or open source software. This article is comprised of a discussion of FOSS (including that suitable for eGovernment), an explanation of the importance of FOSS for developing countries, a justification of government's centrality to the introduction of FOSS and a consideration of policies and initiatives undertaken by governments in developing countries in Southeast Asia.

+1381,Article,Indirectly predicting the maintenance effort of open-source software,"An accurate maintenance effort model is essential for a successful software maintenance process. Maintenance effort is usually measured in person-hours used to perform a maintenance task. However, maintenance effort data are usually only available for strictly managed software, such as closed-source software. In other software projects that do not have complete maintenance records, especially some open-source software, there are no direct data for maintenance effort, which precludes the establishment of a maintenance effort model. In this paper, we report a series of studies aimed at presenting a method for indirectly predicting the maintenance effort of open-source software. This report covers two parts of our research. First, we examine the maintenance data from NASA SEL closed-source software projects and identify some software measures that can be used to indirectly represent maintenance effort. Second, based on the findings in the first part, we analyze 121 recent versions of Linux, and use linear regression to construct two indirect maintenance effort models for the Linux project. Our study demonstrates the applicability of this approach to indirectly predicting the maintenance effort and improving the software maintenance process.

""{Knowledge} and {Organisation} in the {Theory} of the {MNC}","Foss provides an interesting economic theory for the analysis of the MNC and knowledge. However, he defines knowledge in terms that make it amenable to a certain form of economic analysis, and thus overlooks potential insights from other perspectives. As soon as sociological issues are taken into account, the concept of knowledge has to be broadened, and also his theory of control. In particular, the role of the community or group in knowledge creation has to be allowed for. Although sociological and economics-based explanations are sometimes presented as conflicting alternatives, there is no inevitable reason why sociological and economics-based perspectives cannot be integrated in a common framework.",10.1007/s10997-005-3546-7
+1384,Article,Knowledge management in OSS - an enterprise information system for the telecommunications industry,"Knowledge management in Enterprise Information Systems (EIS) has become one of the hottest research topics in the last few years. Operations Support Systems (OSS) is one kind of EIS, which is becoming increasingly popular in the telecommunications industry. However, the academic research on knowledge management in OSS is sparse. In this paper, a knowledge management system for OSS is proposed in the framework of systems theory. Knowledge, knowledge management, organization and information technology are the four main interactive elements in the knowledge management system. The paper proposes that each subsystem of the OSS is to be equipped with knowledge management capacity, and the knowledge management of the OSS is to be realized through its subsystems.

Three primary risks associated with the use of OSS were identified: upstream intellectual property concerns, viral software issues, and non-infringement warranties or intellectual property (IP) indemnity issues. In the context of a field investigation of these risks, several potential scenarios of OSS risk to organizations were identified, with two of them appearing as primary. The first primary scenario is the potential loss of control over revenue generating proprietary software when OSS source code and proprietary software source code are mixed together in one primary software works. The second primary risk scenario is the potential loss of control over software products or services offered within an organization due to legal disputes about intellectual property (IP). Other secondary risk scenarios are discussed as well. Some emerging trends in this area are also reviewed.",10.1109/ITRE.2006.381573

The success of such a seemingly chaotic OSS project will largely depend on how the project leader organizes and motivates the developers to contribute. Grounded on leadership and motivation theories, we proposed and tested a research model that seeks to explain the behavioral effects of a leader on the developers' motivation to contribute. Survey data collected from 118 OSS developers on Sourceforge.net was used to test the research model. The results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and leaders' active management by exception, a form of transactional leadership, is positively related to developers' extrinsic motivation.",10.1145/1125170.1125182
+1394,Article,"Motivation, governance, and the viability of hybrid forms in open source software development","Open source software projects rely on the voluntary efforts of thousands of software developers, yet we know little about why developers choose to participate in this collective development process. This paper inductively derives a framework for understanding participation from the perspective of the individual software developer based on data from two software communities with different governance structures. In both communities, a need for software-related improvements drives initial participation. The majority of participants leave the community once their needs are met, however, a small subset remains involved. For this set of developers, motives evolve over time and participation becomes a hobby. These hobbyists are critical to the long-term viability of the software code: They take on tasks that might otherwise go undone and work to maintain the simplicity and modularity of the code. Governance structures affect this evolution of motives. Implications for firms interested in implementing hybrid strategies designed to combine the advantages of open source software development with proprietary ownership and control are discussed.",10.1287/mnsc.1060.0553

+1403,Article,On the intrinsic and extrinsic motivation of free/libre/open source ({FLOSS}) developers,"Motivation in the context of open source software may be seen as fundamentally different due to the presence of unpaid programmers, implicit rather than explicit forms of control and a different methodology for software development. Since software development is a creative task, the motivation of open source programmers can be compared to individuals in creative industries (Caves 2002). This paper summarizes the important trends in the research on motivation in open source and identifies variables that should be included in future research. Specifically, the current literature favors a taxonomy that considers two components of motivation--intrinsic (e.g., fun, flow, learning, community) and extrinsic (e.g., financial rewards, improving future job prospects, signaling quality). I make a case for incorporating both elements in developing an integrative theory about developer motivation. Three elements are identified as being unique to FLOSS development-diversity of project structures, co-existence of companies and communities and co-existence of creative and commercial elements. The important empirical evidence on FLOSS developer motivation is presented and analyzed. Four factors are identified as important mitigating and moderating factors in the conversation surrounding developer motivation- financial incentives, nature of task, group size and group structure. The role of these factors on developer motivation is discussed.[PUBLICATION ABSTRACT]",10.1007/s12130-006-1002-x

This process is reviewed and illustrated with OsiriX, a fast DICOM viewer program for the Apple Macintosh. Materials and methods OsiriX is an oss for the Apple Macintosh under Mac OS X v10.4 or higher specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: multiplanar reconstruction, surface rendering, volume rendering and maximum Intensity projection. All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT). OsiriX was developed using the Apple Xcode development environment and Cocoa framework as both a DICOM PACS workstation for medical imaging and an image processing software package for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging. Results OsiriX is an open source program by Antoine Rosset, a radiologist and software developer, was designed specifically for the needs of advanced imaging modalities. The software program turns an Apple Macintosh into a DICOM PACS workstation for medical imaging and image processing. OsiriX is distributed free of charge under the GNU General Public License and its source code is available to anyone. This system illustrates how open software development for medical imaging tools can be successfully designed, implemented and disseminated. Conclusion oss development can provide useful cost effective tools tailored to specific needs and clinical tasks. The integrity and quality assurance of open software developed by a community of users does not follow the traditional conformance and certification required for commercial medical software programs. However, open software can lead to innovative solutions designed by users better suited for specific tasks.",10.1007/s11548-006-0056-2

+1429,Article,The Gaggle: An open-source software system for integrating bioinformatics software and data sources,"Background: Systems biologists work with many kinds of data, from many different sources, using a variety of software tools. Each of these tools typically excels at one type of analysis, such as of microarrays, of metabolic networks and of predicted protein structure. A crucial challenge is to combine the capabilities of these (and other forthcoming) data resources and tools to create a data exploration and analysis environment that does justice to the variety and complexity of systems biology data sets. A solution to this problem should recognize that data types, formats and software in this high throughput age of biology are constantly changing. Results: In this paper we describe the Gaggle -a simple, open-source Java software environment that helps to solve the problem of software and database integration. Guided by the classic software engineering strategy of separation of concerns and a policy of semantic flexibility, it integrates existing popular programs and web resources into a user-friendly, easily-extended environment. We demonstrate that four simple data types (names, matrices, networks, and associative arrays) are sufficient to bring together diverse databases and software. We highlight some capabilities of the Gaggle with an exploration of Helicobacter pylori pathogenesis genes, in which we identify a putative ricin-like protein -a discovery made possible by simultaneous data exploration using a wide range of publicly available data and a variety of popular bioinformatics software tools. Conclusion: We have integrated diverse databases (for example, KEGG, BioCyc, String) and software (Cytoscape, DataMatrixViewer, R statistical environment, and TIGR Microarray Expression Viewer). Through this loose coupling of diverse software and databases the Gaggle enables simultaneous exploration of experimental data (mRNA and protein abundance, protein-protein and protein-DNA interactions), functional associations (operon, chromosomal proximity, phylogenetic pattern), metabolic pathways (KEGG) and Pubmed abstracts (STRING web resource), creating an exploratory environment useful to `web browser and spreadsheet biologists', to statistically savvy computational biologists, and those in between.

+1431,Article,The impact of ideology on effectiveness in open source software development teams,"The emerging work on understanding open source software has questioned what leads to effectiveness in OSS development teams in the absence of formal controls, and it has pointed to the importance of ideology. This paper develops a framework of the OSS community ideology (including specific norms, beliefs, and values) and a theoretical model to show how adherence to components of the ideology impacts effectiveness in OSS teams. The model is based on the idea that the tenets of the OSS ideology motivate behaviors that enhance cognitive trust and communication quality and encourage identification with the project team, which enhances affective trust. Trust and communication in turn impact OSS team effectiveness. The research considers two kinds of effectiveness in OSS teams: the attraction and retention of developer input and the generation of project outputs. Hypotheses regarding antecedents to each are developed. Hypotheses are tested using survey and objective data on OSS projects. Results support the main thesis that OSS team members' adherence to the tenets of the OSS community ideology impacts OSS team effectiveness and reveal that different components impact effectiveness in different ways. Of particular interest is the finding that adherence to some ideological components was beneficial to the effectiveness of the team in terms of attracting and retaining input, but detrimental to the output of the team.

The purpose here is to examine the role and power of software in the economy and review the economic impacts of the trend to OSS on the software industry, largely from a European industrial and social perspective. The paper briefly traces the economic significance of the software industry and the dominance in packaged software of the large US publishers, the phenomena of natural monopolies building in software packages, and the need for different industry structure for Europe, as it exhibits a small to medium-sized enterprise (SME) and system integrator structure. It then examines the balancing affects of OSS. The paper also addresses the role that poor software plays in creating new costs or externalities for its users when it fails, contrasting the robustness of open source in defect repair. The paper finds that the way forward in economic terms for Europe may well be to follow and encourage OSS for reasons of creating a strong software industry and for a counterbalance to current monopolistic trends. The paper's findings emphasise the need for investment, education and encouragement in OSS, by both the public and private sectors, to build a strong knowledge-based society in Europe. The paper introduces the ideas of the basic economic mechanisms of volume sales of software as a good, with analysis of the industry impacts of confluence of the network effect coupled with the law of increasing returns with volume to drive monopolistic positions in the proprietary software package industry.",10.1108/14636690610664633

+1443,InProceedings,Understanding Open Source Software through Software Archaeology: The Case of Nethack,"In this study open source software was examined from an archaeological perspective. The objective: to explore the evolution of a long-lived open source project with the intention of learning how code evolution has progressed over time. This investigation provides a case study of Nethack, an enormously popular open source game that has been in development for more than a decade. The Goal Question Metric approach was employed to derive measurement goals for the evaluation of open source software (OSS) evolution in Nethack. According to Lehman's laws, the incremental growth size of successive releases tends to decline during the active life of an evolving program. Our results demonstrate that the evolution patterns observed for Nethack do not consistently conform to Lehman's laws. The growth in Nethack's tarball distribution size, as well as lines of code, exhibited a linear increase in growth in this investigation. Additionally, Lehman's laws dictate that the complexity of a system will increase as it ages. Interestingly, in Nethack, the McCabe cyclomatic complexity was found to decrease with successive releases while the Halstead complexity increased. These results suggest that while the structure complexity of Nethack declined with successive releases, the complexity of calculational logic increased. These findings raise questions concerning the evolution of other OSS applications.",10.1109/SEW.2006.37

To our knowledge, this is the first model of OSS evolution that includes four significant factors: productivity limited by the complexity of software modules, the software's fitness for purpose, the motivation of developers, and the role of users in defining requirements. The model was evaluated by comparing the simulated results against four measures of software evolution (system size, proportion of highly complex modules, level of complexity control work, and distribution of changes) for four large OSS systems.

New so-called third generation (3G) or triple play services can be delivered to the market by means of using these architectures as well as respective IT support systems. Furthermore, various market players, stakeholders or alliances will come up at the telecommunications arena. The paper will systematic ally consider all these subject matters and elaborate that the use of New Generation Systems and Software (NGOSS) principles will leverage the OSS/BSS as well as IMS/SDP promise. In other words, to provide efficiently IMS/SDP based services requires an ``IMS/SDP ready{''} OSS/BSS. There will be lots of well-known as well as quite a few new features to be provided by such an OSS/BSS. One example is that an ``IMS/SDP ready{''} OSS/BSS does not only provide all the existing services very quickly.. it must also be able to support the design and creation of new types of services including new types of network/IT resources which allow these new kinds of services at all. This will impact the whole IMS/SDP as well as OSS/BSS environment, beginning with the Service Creation Environment (SCE) up to the extension of the Inventory Management System as the heart of the operational processes. However, the use of such an OSS/BSS in concert with the IMS/SDP will play a key role in allowing the operator or service provider to reduce Operational Expenditure while at the same time, delivering the efficiencies needed to speed up both the service and infrastructure provisioning processes.

In order to consider the effect of each software component on the reliability of an entire system under such open source software, we propose a new approach to software reliability assessment by creating a fusion of neural network and software reliability growth model based on stochastic differential equations. Also, we analyze actual software fault count data to show numerical examples of software reliability assessment for the open source software.",NA

For optimal impact, the limited time and effort for complexity control, called anti-regressive work, should be applied to the elements of the system which are frequently changed and are complex. Based on this, we propose a maintenance guidance model (MGM) which is tested against real-world data. MGM takes into account several dimensions of complexity: size, structural complexity and coupling. Results show that maintainers of the eight open source systems studied tend, in general, to prioritize their anti-regressive work in line with the predictions given by our MGM, even though, divergences also exist. MGM offers a history-based alternative to existing approaches to the identification of elements for anti-regressive work, most of which use static code characteristics only.",NA

+1469,InCollection,"Addressing Challenges of OSS Application Development for IT Naive, Poor Users","IT naive, low-budget end-users - such as those in most small to medium enterprises or small city governments - require specific applications which are usually simple information systems with no technological challenges. Their low budget characteristics make the vertical applications these users need natural targets for free/open source software (F/OSS) development efforts. The lack of technological challenges however, does not motivate experienced programmers to specify, code and test verticals. We are thus left with a problem of developing verticals which do not attract ROSS volunteers and whose end-users are not even able to specify them (they are IT naive) nor pay for professional help to do the job for them. This paper proposes a solution to such a problem. The solution is organized in the form of a university level F/OSS vertical development contest, which involves computer science professors as project leaders and students as ``volunteered{''} programmers. Quality of the produced software is guaranteed by means of contest infrastructure, services, support kits which bring vertical seed code, coding and documentation standards and code reviews by the contest steering committee members. One such contest is being carried out in Brazil with the engagement of 5 universities to gain experience and evaluate contest risks, effectiveness and running processes. Results so far are encouraging having produced an already useful city government application. Results also indicated required adjustments in the technical details and procedures but also high levels of professor and student motivation. A nation-wide contest to produce more verticals for small city governments is scheduled to happen next.",NA

This method is embedded in a software package available online from www.esat.kuleuven.be/sista/members/biomed/new/ with a graphical user interface, under an open source license, which means that the source code is freely available and easy to adapt to specific needs of the user. The quantitation problem is mathematically formulated as a separable nonlinear least-squares fitting problem, which is numerically solved using a modified variable-projection procedure. A macromolecular baseline is incorporated into the fit via nonparametric modelling, efficiently implemented using penalized splines. Unwanted components such as residual water are removed with a maximum-phase FIR filter. Constraints on the phases, dampings and frequencies of the metabolites can be imposed. AQSES has been tested on simulated MR spectra with several types of disturbance and on short echo time in vivo proton MR spectra. Results show that AQSES is robust, easy to use and very flexible.

In the case of model organisms, the data available are numerous, given the degree of redundancy in the deposited EST data. There are several available bioinformatics tools that can be used to mine this data; however, using them requires a certain level of expertise: the tools have to be used sequentially with accompanying format conversion and steps like clustering and assembly of sequences become time-intensive jobs even for moderately sized datasets. We report here a pipeline of open source software extended to run on multiple CPU architectures that can be used to mine large EST datasets for SNPs and identify restriction sites for assaying the SNPs so that cost-effective CAPS assays can be developed for SNP genotyping in genetics and breeding applications. At the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), the pipeline has been implemented to run on a Paracel high-performance system consisting of four dual AMD Opteron processors running Linux with MPICH. The pipeline can be accessed through user-friendly web interfaces at http://hpc.icrisat.cgiar.org/PBSWeb and is available on request for academic use. We have validated the developed pipeline by mining chickpea ESTs for interspecies SNPs, development of CAPS assays for SNP genotyping, and confirmation of restriction digestion pattern at the sequence level.

+1488,Article,Comment: Virtual neighborhood watch: Open source software and community policing against cybercrime,"Cybercrime-crime committed through the use of a computer-is a real and growing problem that costs governments, businesses, and individual computer users millions of dollars annually and that facilitates many of the same crimes committed in realspace, such as identity theft and the trafficking of child pornography, only on a larger scale. However, the current strategies deployed by law enforcement to combat cybercrime have proven ineffective. Borne out of traditional notions of criminal behavior, these strategies and tactics are often ill-suited to prevent or punish cybercrime, which often defies the traditional notions of criminal behavior bounded by the corporeal world such as scale and proximity. This Comment argues that a more effective methodology in the fight against cybercrime is to develop a model of community policing, in which the power to deter and prevent cybercrime is divested into the hands of individual computer users. One such strategy for achieving effective community policing against cybercrime is through the increased use of open-source soft-ware, software in which users are given access to the underlying source code and may make modifications to that source code in order to ameliorate vulnerabilities that may enable cybercrime. This Comment looks at the development of traditional community policing strategies and argues that the increased use of open source software-spurned by greater involvement by government and corporations-may be a more effective technique in the fight against cybercrime.",NA

In a recent series of papers (DE MENEZES M. A. and BARABASI A.-L., Phys. Rev. Lett., 92 ( 2004) 28701; 93 ( 2004) 68701; YOOK S. H. and de MENEZES M. A., Europhys. Lett., 72 ( 2005) 541), de Menezes and co-workers have shown how to separate internal dynamics from external fluctuations by capturing the simultaneous activity of many system's components. In spite of software development being a planned activity, the analysis of fluctuations reveals how external driving forces can be only observed at weekly and higher time scales. Hourly and higher change frequencies mostly relate to internal maintenance activities. There is a crossover from endogenous to exogenous activity depending on the average number of. le changes. This new evidence suggests that software development is a non-homogeneous design activity where stronger efforts focus in a few project files. The crossover can be explained with a Langevin equation associated to the cascading process, where changes to any. le trigger additional changes to its neighbours in the software network. In addition, analysis of fluctuations enables us to detect whether a software system can be decomposed into several subsystems with different development dynamics.

The submission of patches is the major way that participants outside of the core group of developers make contributions. We argue that the process of patch submission and acceptance into the codebase is an important piece of the open source puzzle and that the use of patch-related data can be helpful in understanding how OSS projects work. We present our methods in identifying the submission and acceptance of patches and give results and evaluation in applying these methods to the Apache webserver, Python interpreter, Postgres SQL database, and (with limitations) MySQL database projects.

In 2005, several university libraries, university college libraries and other research libraries met and discussed a joint effort to create institutional archives. The meeting resulted in the Pepia project with BIBSYS as a software partner. The project group decided to use the open source system DSpace as a software platform. A standard DSpace installation runs on a Tomcat servlet container. BIBSYS does not use this container, and we therefore needed to configure DSpace to get it to run successfully on our server. In addition we had some problems with integrating the DSpace development structure with our integrated development environment. Further we needed to create a new build process that effectively could build more than 30 applications from one source code. These changes were quite time consuming, but they were necessary so that we could have an efficient work environment. Out of the box DSpace has many of the functionalities that an institutional archive requires. In spite of this we needed to alter some of the functionality, especially the user management system. DSpace is a complex system, but with the active community we could get the help we needed. BIBSYS Brage, the result of the Pepia project, was launched as a beta version in December 2006.

The famous phrase ""Tragedy of the Commons"" describes a situation where a natural resource commons, such as a pasture, or a water supply, gets depleted because of overuse. The tragedy in FLOSS commons is distinctly different -- it occurs when collective action ceases before a software product is produced or reaches its full potential. This paper builds on previous work about defining success in FLOSS projects by taking a collective action perspective. We first report the results of interviews with FLOSS developers regarding our ideas about success and failure in FLOSS projects. Building on those interviews and previous work, we then describe our criteria for defining success/tragedy in FLOSS commons.

+1532,InProceedings,Intrusion detection in open source software via dynamic aspects,"Aspect-Oriented Programming (AOP) is an emerging software engineering methodology, which has been used to assist in the removal of crosscutting concerns from traditional methods of software development. As an example, software used to determine whether a user has appropriate security clearance might be scattered throughout the many modules, which require this check. Utilising AOP, ``aspects{''} are ``woven{''} into the software either in a ``static{''} method, during compilation, or a ``dynamic{''} method while the program is executing. The ``join points{''} in a program are the points where these aspects are applied. The ``aspect{''} code is written once and ``woven{''} in to the modules at join points. Typical aspects involve logging changes to a database and monitoring memory usage. Our focus is on aspects related to security and intrusion incident detection. Dynamic weaving allows aspects to be woven in and out as the program is executing. However the base code often must be compiled with additional ``syntactic sugar{''} - additions that are required for the later connection of dynamic aspects. This paper presents a new technique to enable dynamically loaded security modules to be added into existing C/C++ code on the fly while the program is executing. Our tool is a Run-Time Event Monitoring System called ``dynamicHook{''}, implemented on a standard Linux platform using existing Linux tools, which tests each potential join point for the required activation of advice. Our system does not need to modify the executable files, but instead we compile in special ``linkage{''} between the base code and potential aspects which are then called as dynamically linked routines located in shared libraries. Our scheme does not require any new syntax or language extensions or rely on code transformations; we thus use it for adding intrusion detection methodologies to pre-existing off-the-shelf open source software.",NA

This shift is not only redefining the software industry but also the way we teach and learn in our software engineering (SE) courses. But for many universities F/OSS is seen as an optional low cost technology to support the IT infrastructure and administrational duties. Few see F/OSS as an opportunity for students to learn the SE concepts and skills we teach. Furthermore, it is still an open question as to whether the F/OSS methodology can be effectively used to teach SE courses within the formally structured curriculum in most universities. This paper discusses F/OSS projects as bazaars of learning that offer a meaningful learning context. The discussion is centered on a pilot study in which students were involved in software testing in F/OSS projects. We present the teaching and learning framework we used in the pilot study and report on our experiences, lessons learned, and some practical problems we encountered. Our grading and evaluation approach show that the students did relatively well as bug hunters and reporters. Results from two online surveys indicate that students are motivated in participating in software testing in the bazaar, and they are willing to participate in project activities long after their graduation. The study reveals one possible way SE educators can teach and integrate F/OSS into their formal curricular structure. [PUBLICATION ABSTRACT]",NA

+1541,InProceedings,Managing knowledge within Military Open Source Software (MOSS) projects,"The Open Source Software (OSS) development model is arousing increasing interest from both practitioners and theorists. OSS models are congenial for both private companies and public administrations since they provide software users and suppliers with highly responsive and innovative development models which are likely to reduce costs and to provide additional autonomy within critical technological domains. OSS are characterized by the distribution of source code to any developer interested in contributing to the provision of the code. License terms allow a developer to make unlimited copies of the source code which can be modified indefinitely by developers to fulfil particular needs. Each developer is then free to distribute her work and exploit it commercially depending on license terms. The U.S. Department of Defense (DoD) is currently introducing Open Source Software (OSS) development models through its Open Technology Development (OTD) project (Herz et al. 2006). OSS adoption is becoming popular for military purposes. Indeed, the digital transformation of the U.S. military has generated a strong need for new modes of software management. In this context, the OTD project tends to set up an innovative model for software acquisition, maintenance, updating, and renewing. Focusing on the adoption of Military Open Source Software (MOSS) models by the U.S. Department of Defense (DoD), this article suggests that the open nature of OSS development platforms induces significant organizational changes related to the acquisition, transformation and creation of a variety of OSS core capabilities. Furthermore, we suggest that the U.S. military organizations should perceive modularity in software architecture as a means to establish effective modes of knowledge management and innovation. Building on the distinction between architectural and component knowledge, we find that modular source code structuring facilitates the division, distribution and coordination of both architectural knowledge and component knowledge within heterogeneous OSS developers' communities.",NA

As the development and use of OSS becomes prominent, the question of its integration in education arises. In this paper, the following practices fundamental to projects and processes in software engineering are examined from an OSS perspective: project management; process, workflows, and collaborative activities; modeling and specification; deployment of standards; documentation; and quality assurance and evaluation. Based on a pragmatic framework, the prospects of integrating OSS in a traditional software engineering curriculum are outlined and concerns in realizing them are given. In doing so, the cases of the adoption of OSS process model, use of OSS as a Computer Aided Software Engineering (CASE) tool, OSS as a standalone sub-system, and open source code reuse are considered. We present some of the trade-offs that could help educators in decision making towards the use of the OSS environment in software engineering pedagogical contexts. The significance of openly accessible content in general and its relation to OSS in particular is briefly highlighted.",NA

We use proxies based on empirical data collection to provide insight into the degree of Open Source software adoption which has already occurred. Software tools were developed to analyze web host software on the public Internet within each ASEAN country's country-level domain.

However, the problematic nature of OSS adoption is readily evidenced in the fairly frequent reports of problems, unforeseen hold-ups, and outright abandonment of OSS implementation over time. Beaumont Hospital, an Irish public sector organization, have embarked on the adoption of a range of OSS applications over several years, some of which have been successfully deployed and remain in live use within the organisation, whereas others, despite achieving high levels of assimilation over a number of years, have not been ultimately retained in live use in the organization. Using a longitudinal case study, we discuss in depth the deployment process for two OSS applications - the desktop application suite whose deployment was unsuccessful ultimately, and the email application which was successfully deployed. To our knowledge, this is the first such in-depth study into successful and unsuccessful OSS implementation. Given that our study was a longitudinal one in a single organization, we can control a number of potentially important influencing elements which would not be possible if multiple organizations were involved. In particular, the complex interaction of issues to do with voluntariness of adoption, image, trialability and absorptive capacity were critical influences in the process.",NA

In this paper we explore the process of OSS innovation and highlight the impact of increased competition and different cost structures on innovative activity in the industry, which has been neglected in the literature thus far. In a simple model, we formalize the innovation impact of OSS entry by examining a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model takes into account development costs and total cost of ownership, whereby the latter captures items such as network externalities. The paper identifies a pro-innovative effect of both intra-OSS and extra-OSS competition. [PUBLICATION ABSTRACT]",NA

An efficient link between sample data and experiment results is absolutely imperative for a successful outcome of a biomedical study. Currently available software solutions are largely limited to large-scale, expensive commercial Laboratory Information Management Systems (LIMS). Acquiring such LIMS indeed can bring laboratory information management to a higher level, but often implies sufficient investment of time, effort and funds, which are not always available. There is a clear need for lightweight open source systems for patient and sample information management. Results: We present a web-based tool for submission, management and retrieval of sample and research subject data. The system secures confidentiality by separating anonymized sample information from individuals' records. It is simple and generic, and can be customised for various biomedical studies. Information can be both entered and accessed using the same web interface. User groups and their privileges can be defined. The system is open-source and is supplied with an on-line tutorial and necessary documentation. It has proven to be successful in a large international collaborative project. Conclusion: The presented system closes the gap between the need and the availability of lightweight software solutions for managing information in biomedical studies involving human research subjects.",10.1186/1471-2105-8-52

Building on information from an extensive dataset of secondary sources and 30 in-depth interviews, I show that de novo entrants have emerged in conjunction with a changing institutional infrastructure and a more pragmatic attitude toward firms that focus on technological benefits rather than ideology. To understand how these firms try to harness the work of these communities, I use the empirical data to derive a 2*2 matrix of different approaches. The X axis reflects whether or not the firms initiated a new community or relied on communities founded by peers, whereas the Y axis represents the degree of participation of the firm in the community. This taxonomy illustrates how de novo entrants are initiating new forms of communities or joining communities established by peers. This suggests that while many of the central pillars of FOSS remains, de novo entrants have emerged to find new ways of making business resulting in various implications for firm strategies and knowledge disclosure.

In keeping with the empirical shift manifest in recent public sphere scholarship and Bruno Latour's idea that socio-technical deliberation is characterized by the inscription of non-humans, I describe the rhetorical manners in which volunteer citizens define and mobilize a mundane artifact-a web site- in a deliberation over the value of FIOS technologies for their government-funded project. Through inscription of the web site as a rhetorical resource and as the embodiment of their disposition toward computer technologies, the volunteers formed and expressed competing understandings of the role of FIOS technologies in sustaining a public sphere. I argue that these competing views are consequential, for they link technical artifacts and political agents in practice, by way of aspirations, obligations, and forms of authority. Furthermore, by claiming a form of agency for technologies in the public sphere, the proponents of F10S technologies are inviting scholars of the public sphere to question the status assigned to technical artifacts in their investigations and theories of the public sphere.",10.1080/00335630701426751

In accordance with such a penetration of the Internet, it is increasing public awareness of the importance of online real-time and interactive functions. Therefore, software development environment has been changing into new development paradigms such as concurrent distributed development environment and the so-called open source project by using network computing technologies. Especially, such OSS (Open Source Software) systems which serve as key components of critical infrastructures in our society are still ever-expanding now. In this paper, we propose a software reliability growth model based on stochastic differential equations in order to consider the active state of the open source project. Especially, we assume that the software failure intensity depends on the time, and the software fault-report phenomena on the bug tracking system keep an irregular state. Also, we analyze actual software fault count data to show numerical examples of software reliability assessment for the OSS. Moreover, we compare our model with the conventional model based on stochastic differential equations in terms of goodness-of-fit for actual data. We show that the proposed model can assist improvement of quality for OSS systems developed under the open source project.",NA

Starting from a baseline system based on Gaussian mixture models that reached state-of-the-art performances during the NIST'04 SRE, final systems with new intersession compensation techniques show a relative gain of around 50\\%. This work highlights that a key element in recent improvements is still the classical maximum a posteriori (MAP) adaptation, while the latest compensation methods have a crucial impact on overall performances. Nuisance attribute projection (NAP) and factor analysis (FA) are examined and shown to provide significant improvements. For FA, a new symmetrical scoring (SFA) approach is proposed. We also show further improvement with an original combination between a support vector machine and SFA. This work is undertaken through the open-source ALIZE toolkit.",10.1109/TASL.2007.902877

I prepared and presented two 3.5 hour tutorials at FLOSS conferences: LinuxAsia in Delhi and O'Reilly's Open Source Conference (OSCON) in Portland. This paper describes these experiences. I first summarize the tutorials, pointing out which research was used and what the interests of the participants were and where more research can bridge the gaps. I then describe an ongoing interaction with a software engineering manager at Microsoft who attended the tutorial and is in the interesting position of taking a Microsoft work group open. Finally I reflect on this experience for lessons about ""transferable research'.",10.1109/FLOSS.2007.13

At the same time, the field of machine learning has developed a large body of powerful learning algorithms for diverse applications. However, the true potential of these methods is not used, since existing implementations are not openly shared, resulting in software with low usability, and weak interoperability. We argue that this situation can be significantly improved by increasing incentives for researchers to publish their software under an open source model. Additionally, we outline the problems authors are faced with when trying to publish algorithmic implementations of machine learning methods. We believe that a resource of peer reviewed software accompanied by short articles would be highly valuable to both the machine learning and the general scientific community.",NA
+1613,Article,The commercialisation of bioinformatics and the threat of open-source software: {Research} and {Regulation},"This study investigates the commercialisation process of a select group of bioinformatics companies and the impact of open-source software. Using the research-development-application translation model provides a framework for managers as an iterative mechanism. A Value Creation Pipeline is then introduced with five phases of the commercialisation process that provide specific financial benchmarks that can guide the firm through to successful commercialisation. Using trend and financial ratio analyses relative to returns, profitability and liquidity, the study finds that the surge in open-source licenses between 2003 and 2005 limited the sales for some firms. As for the claim that open-source software negatively impacts the success of bioinformatics commercialisation, there was little evidence to suggest a direct cause-and-effect relationship. Losses in returns, profitability and liquidity were just as common before the rise of open source as after its emergence. When firms report an overall record over a nine-year period of poor return on investment, assets and equity, there is little to attract potential investors. The lesson that can be drawn is that the innovation process and financial tracking must be integrated to ensure efficient and profitable use of investor funds.

This quality degradation effect, called entropy, is a cause for higher maintenance costs. In the Open Source context, the quality of code is a fundamental tenet of open software developers. As a consequence, the quality degradation principle measured by entropy cannot be assumed to be valid. The goal of the paper is to analyze the entropy of Open Source applications by measuring the evolution of maintenance costs over time. Analyses are based on cost data collected from a sample of 1251 Open Source application versions, compared with the costs estimated with a traditional model for proprietary software. Findings indicate that Open Source applications are less subject to entropy, have lower maintenance costs and also a lower need for maintenance interventions aimed at restoring quality. Finally, results show that a lower entropy is favored by greater functional simplicity.",NA

+1619,Article,The impact of participation in virtual brand communities on consumer trust and loyalty -: The case of free software,"Purpose - The importance of virtual brand communities is growing day by day as a result of consumers increasingly using online tools to contact fellow consumers in order to get information on which to base their decisions. For this reason, this work aims to explore some of the effects of participation in a virtual brand community on consumer behaviour. Design/methodology/approach - The paper proposes the positive effects of participation in a virtual community on both consumer trust and loyalty to the product, brand or organisation around which the community is developed. In addition, it also proposes a positive effect of trust on consumer loyalty. After the validations of measurement scales, the hypotheses are contrasted through structural modelling. Findings - The data, obtained through a web survey using members of several free software virtual communities, show that participation in the activities carried out in a virtual community may foster consumer trust and loyalty to the mutual interest of the community (the free software in this case). In addition, the study also found a positive and significant effect of consumer trust on loyalty. Research limitations/implications - Data were collected thanks to a web survey using Spanish-speaking subjects. Practical implications - The high costs every company has to face in order to get new customers make it increasingly necessary to reinforce the ties established with customers. In this respect, this study has shown that managers may foster consumer trust and loyalty by developing virtual brand communities and promoting consumers' participation in them. Originality/value - Most of the works that are focused on virtual communities have been conducted at the conceptual level. Thus, with the aim of moving on this topic, this study analyses empirically the effects of participation in a virtual brand community on consumer behaviour.",10.1108/14684520710841766
+1622,Article,The politics of translation of the revised version: Evidence from the newly discovered notebooks of Brooke Foss Westcott,"The English Revision of the Authorized Version of the Bible was initiated in 1870 and drew upon the finest scholarship of established and non-conformist clergymen. It ushered in one of the most contentious, politicized debates in the history of Bible translation, even as it finally broke the hold of the King James Version. The conflict over the revision has been known only through published sources. A seal has remained over the dynamics between the two dozen members of the committee responsible for the revision of the New Testament. The official minute book yields nothing of the textual, grammatical, and translational debates nor of the voting patterns governing decisions. This gap can now be overcome with the discovery of two of the twenty-one notebooks kept by Brooke Foss Westcott, one of the members of the committee. His detailed account of each members' arguments over almost every verse of Matthew's Gospel provides an invaluable insight into the variety and alignments of English biblical scholarship in the nineteenth century.",10.1093/jts/flm001

However, there are numerous issues associated with OSS, including its influence on the total cost of ownership (TCO) and supportability and upgradeability risks. While savings from obtaining a free copy of the software can be significant, software accounts for an average of 10\\% of TCO, while the majority of the costs are associated with project staffing. OSS requires significant investment into staffing because it needs to be carefully selected, customized, and installed. In addition, global communities may gather and dissolve at their will, so guarantees of support, revision, and bug fixes are minimal. Yet companies can gain competitive advantage through an ability to customize software to address specific business issues and exercising control over development, revision schedules, and modifications. OSS is not a panacea from the rising software costs. Instead, it is a serious initiative that has benefits, disadvantages, and risks associated with it.",10.1007/978-0-387-72486-7\\_28

The internal heterogeneity of project contributors questions the functioning of collective action: how can commitments that are so dissimilar be put together? Our objective is to consider FLOSS communities as going concerns which necessitate a minimum of order and common, shared, social rules to function. Through an in-depth and diachronic analysis of the Spip project, we present two classical modes of social regulation: a control regulation centred on the product and an autonomous regulation reflecting the differentiated commitments. Our data shows that the meaning, value and legitimacy of contributors' involvements are defined and rated more collectively, through exchanges, judgments, and evaluations. A third regulation mode, called distributed community regulation and aimed at creating and transforming shared rules that produces recognition and stratification, is then presented.

Infrastructures and FLOSS software exhibit multiplicity: as objects they both change and stay the same. Whilst the implications of multiplicity with respect to infrastructure have been well-documented, with respect to FLOSS, they remain under-explored. Through examining how the DBE engaged new participants we were able to explore the nature of the FLOSS software object by asking the implied question: engagement with what? We draw on recent analysis by Law and Singleton to show how the innovative yet non-existent potentiality of the DBE was as significant to engagement as its steadily growing codebase. We argue that acknowledging the materiality and immateriality of the FLOSS software object has important consequences for management of, and engagement with, FLOSS projects.

A problem is, however, how to identify applications in these latter categories that are important. Software distributions specify the dependencies needed to build and to run a given software application. We use this information to create a dependency graph of the applications contained in such a distribution. We explore the characteristics of this graph, and use it to define some metrics to quantify the dependencies (and dependents) of a given software application. We demonstrate that some applications that are invisible to the final user (such as libraries) are widely used by end-user applications.

Making this interface universally accessible and more interactive is a long term goal still far from being achieved. Universally accessible browsers require novel interaction modalities and additional functionalities, for which existing browsers tend to provide only partial solutions. Although functionality for Web accessibility can be found as open source and free software components, their reuse and integration is complex because they were developed in diverse implementation environments, following standards and conventions incompatible with the Web.To enable the integration of existing partial solutions within a mainstream Web browser environment, we have developed a middleware infrastructure, AMICO:WEB. This enables browser access to a wide variety of open source and free software components. The main contribution of AMICO:WEB is in enabling the syntactic interoperability between Web extension mechanisms and a variety of integration mechanisms used by open source and free software components.

The objective of our study is to understand and to model the dynamics of the OSS design process that takes place in mailing list exchanges. We develop a method to study distant and asynchronous collaborative design activity based on an analysis of quoting practices. We analyze and visualize three aspects of the online dynamics: social, thematic temporal, and design. We show that roles emerge during discussions according to the involvement and the position of the participants in the discussions and how they influence participation in the design discussions. In our analysis of the thematic temporal dynamics of discussion, we examine how themes of discussion emerge, diverge, and are refined over time. To understand the design dynamics, we perform a content analysis of messages exchanged between developers to reveal how the online discussions reflect the ``work flow{''} of the project: it provides us with a picture of the collaborative design process in the OSS community. These combined results clarify how knowledge and artefacts are elaborated in this epistemic, exploration-oriented, OSS community. Finally, we outline the need to automate of our method to extend our results. The proposed automation could have implications for both researchers and participants in OSS communities.

+1656,Article,A strategic analysis for successful open source software utilization based on a structural equation model,"Commercial software companies face many challenges when competing in today's fast moving and competitive industry environment. Recently, the use of open source software (OSS) has been proposed as a possible way to address those challenges. OSS provides many benefits, including high-quality software and substantial profits. Nevertheless, OSS has not been effectively utilized in real business. The purpose of this paper is to find what affects the utilization of OSS. For this study, we propose a structural equation model (SEM) to analyze the relationships between the quality factors based on ISO/IEC 9126 and OSS utilization. In addition, we suggest an open source software utilization index (OSSUI) based on the proposed SEM. The results provide us with the controllable feedback information to improve user (programmer) satisfaction during OSS utilization. (C) 2007 Elsevier Inc.

The OSS development project is operated by virtual team that mainly consists of software developers in online community. In this paper, the main characteristics of OSS development are firstly discussed. OSS is significant to the China National Information Industry. However, the Internet-based open source communities are not well developed in China. To improve the open source practice in China, the influencing factors of virtual team performance in the open source community are analyzed from the systems perspective, including Agents Attributes Dimension (individual effort and technical abilities), Interactions Among the Agents Dimension (affective trust, cognitive trust and communication) and Environment Dimension (open source culture, community infrastructure, fund support and government policies support). Then a theoretical framework of factors influencing the performance of OSS development virtual team and corresponding hypotheses are proposed.",NA

The OSS adoption could lead to lower production and transaction costs and thus lead to higher profitability. However, the adoption process is complex and involves many internal as well as external factors. Hence, information about the rate of diffusion could be useful to decision makers and support them in justifying their decisions. We study a variety of technology diffusion models and their application to OSS. Epidemic, Probit, and Bass models are compared on their interpretations of technology diffusion. We develop a game theoretic framework where knowledge of OSS diffusion rate could lead to information asymmetry and work in favor of an adopting firm in terms of gaining competitive advantage over its competitors.",NA

It stems from a need to reassess strategic spending within an academic department on music IT, and an interest in the advantages of open source software for managing musical and collaborative projects. The authors discuss the most practical way of assessing the use of Linux, a completely open source software platform with the aim of understanding how compositional paradigms migrate between computer operating systems, noting similarities between systems, and highlighting strengths and weaknesses of the process. It is apparent that the Linux platform has much to offer, but remains limited in a number of areas of music IT that are used extensively in academia, industry and at home. However, as a platform for teaching and learning computer music it is an ideal tool, though we conclude that some `introduction' at the outset is required for those who are uninitiated to a Linux-based system. The teaching and learning initiative expected students, by the end of a three-year undergraduate degree programme, to be creating their own tools and to have a good understanding of related operating systems.",10.1386/jmte.1.2and3.113\\_1
+1663,InProceedings,An Empirical Study of Evolution of Inheritance in Java OSS,"Previous studies of Object-Oriented (OO) software have reported avoidance of the inheritance mechanism and cast doubt on the wisdom of ‘deep’ inheritance levels. From an evolutionary perspective, the picture is unclear - we still know relatively little about how, over time, changes tend to be applied by developers. Our conjecture is that an inheritance hierarchy will tend to grow ‘breadth-wise’ rather than ‘depth-wise’. This claim is made on the basis that developers will avoid extending depth in favour of breadth because of the inherent complexity of having to understand the functionality of superclasses. Thus the goal of our study is to investigate this empirically. We conduct an empirical study of seven Java Open-Source Systems (OSSs) over a series of releases to observe the nature and location of changes within the inheritance hierarchies. Results showed a strong tendency for classes to be added at levels one and two of the hierarchy (rather than anywhere else). Over 96% of classes added over the course of the versions of all systems were at level 1 or level 2. The results suggest that changes cluster in the shallow levels of a hierarchy; this is relevant for developers since it indicates where remedial activities such as refactoring should be focused.",10.1109/ASWEC.2008.78

Although researchers have been studying the evolution of software systems since the early 70s, the study on the evolution of software development teams remains rare. Such evolutionary patterns and their impact on software quality are especially important in the context of OSS (Open Source Software) development, where a group of volunteer developers collaborate online for an extended period of time. By analyzing how social networks of developers evolve over time while building OSS products, we can gain knowledge and experience to improve the effectiveness and efficiency of resource management and distribution in future OSS projects. To this end, we studied the evolution of the developer communities using a suite of OSS products developed under the KOffice project. We found that in general, the social networks of OSS developer communities change over time in certain ways. Identifying such patterns can help OSS managers better understand the unique process of OSS development and improve their management and coordination of the projects.",10.1109/HICSS.2008.58

+1671,InProceedings,An Open Source Software System For Robot Audition HARK and Its Evaluation,"Robot capability of listening to several things at once by its own ears, that is, robot audition, is important in improving human-robot interaction. The critical issue in robot audition is real-time processing in noisy environments with high flexibility to support various kinds of robots and hardware configurations. This paper presents open-source robot audition software, called ``HARK{''}, which includes sound source localization, separation, and automatic speech recognition (ASR). Since separated sounds suffer from spectral distortion due to separation, HARK generates a temporal-frequency map of reliability called ``missing feature mask{''}, for features of separated sounds. Then separated sounds are recognized by the Missing-Feature Theory (MFT) based ASR with missing feature masks. HARK is implemented on the middleware called ``FlowDesigner{''} to share intermediate audio data, which provides real-time processing. HARK's performance in recognition of noisy/simultaneous speech is shown by using three humanoid robots, Honda ASIMO, SIG2 and Robovie with different microphone layouts.",NA
+1673,InProceedings,An investigation into the implementation of open source software within the SA government: an emerging expansion model,"Open source software (OSS) is increasingly becoming an alternative for proprietary software (PS), particularly in the government sector globally. The adoption and implementation of OSS by the government sector is cited as one of the enablers for the adoption of OSS by the private sector. It is also apparent that in the government sector internationally, OSS is seen as a viable technology for reasons such as lowering software costs, growing local software development industry, and bridging the digital divide. In South Africa (SA), an OSS policy that mandates OSS usage within ministries is in place. But according to various open source advocates, little has happened with regards to OSS implementation in the SA government. This paper reports on the current status of OSS usage within the SA government by surveying forty (40) national departments, targeting Information Technology (IT) directors and managers. The results indicate that OSS usage within the ministries is not yet extensive as required by the OSS policy. Various challenges and obstacles are hampering full OSS implementation within the ministries. The contribution of this research paper is an OSS expansion model, which is proposed as a possible solution to improve the current status of OSS usage within the SA government departments.

+1674,InProceedings,Analysis of open source software in enterprise informatization,"Enterprise informatization experiences three phases information islet modeling, intranet modeling and integrated enterprise modeling. The traditional market failure argument suggests that innovation is characterized by high investment and low copy cost, and firms have difficulty in internalizing the fruits of their innovative effort. Thus, technology firms are seeking more patents, expanding their scope and overhauling their business models around intellectual property. Yet paradoxically, with the progress and development of information technology, open source software (OSS) plays an important role in expanding enterprise informatization. For example, Linux is developed quickly by this open way. Some firms have found the ways of making money by opening up their treasure-chest of innovation and sharing it with others. The rise of open-source software is one example. In this article, the author introduces a model of OSS based on its network effects to understand how the enterprises decide their activities in this open market competition. This article describes the inherent reasons of open source movement from the view of the oligopoly structure. At the same time, this article analyses the effect of leader enterprise and follower enterprise on market structure and the different activities of these enterprises after the source has been opened. Finally, we make suggestions that companies at the leading edge are often in such a strong position that they do need the support of down-streams companies to broaden their technologies successfully and to decrease their risks in order to leverage the value of the technological portfolio. On the other hand, this article suggests that follower enterprises have incentive to take part in the development of open-source software only when the market has grown up.",NA
+1676,InProceedings,Analyzing impact of interface implementation efforts on the structure of a software market -: OSS/BSS market polarization scenario,"A vertical software market is usually subject to the process of disintegration resulting in a market where different layers of software are provided by independent software vendors. However, as argued in this paper, the process of this vertical disintegration may be affected by high investments to software interface implementation and maintenance. Should the required efforts be large, the threshold for entering the market increases, thereby hampering the vertical disintegration process. This study examines the impact of the interface implementation efforts on the vertical market evolution in the case of the so-called operations support systems and business support systems (OSS/BSS) software, which are employed by the telecom operators in order to support their daily operations. The efforts are compared for two prototypical software vendors serving incumbent operators and new operators respectively. Total efforts are an order of magnitude larger in the former case. Furthermore, even if only latest network protocols are taken into account, the efforts are significantly larger in the former case, therefore requiring several times greater number of employees to implement them. Therefore, a conclusion is made that the OSS/BSS market is likely to polarize into the vertical submarket of large software vendors serving incumbent operators, and the submarket of small vendors serving young operators. The latter submarket, due to the lower entry threshold for new vendors is more likely to be vertically disintegrated.",NA

Understanding the structure of software systems can provide useful insights into software engineering efforts and can potentially help the development of complex system models applicable to other domains. In this paper, we analyze one of the most popular open-source Linux meta packages/distributions called the Gentoo Linux. In our analysis, we model software packages as nodes and dependencies among them as edges. Our empirical results show that the resulting Gentoo network cannot be easily explained by existing complex network models. This in turn motivates our research in developing two new network growth models in which a new node is connected to an old node with the probability that depends not only on the degree but also on the ``age{''} of the old node. Through computational and empirical studies, we demonstrate that our models have better explanatory power than the existing ones. In an effort to further explore the properties of these new models, we also present some related analytical results. (C) 2008 Elsevier B.V. All rights reserved.",10.1016/j.physa.2008.06.050

A popular example of open innovation has been open source software (OSS). The key issues facing organizational decision makers considering OSS strategies is, how does the firm create value for the customer while simultaneously extracting value for itself? However, the adoption of OSS as part of an open innovation strategy is a recent phenomenon and many unanswered questions remain. Taking the viewpoint of seven IS/IT decision makers in European firms, this paper reveals how decision makers considered aspects of value creation, capture, and networking in making decisions on adopting open source software. The findings reveal that while decision makers look to open innovation for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.",NA

Correspondingly, the innovation system of the virtual collaboration environment represented by SF.net is an emergent property of two ""coupled"" processes: one involves the interactions among agents searching the locale for information and knowledge resources to use in designing novel software products (i.e., exploration), and the other involves the mobilization of individuals' capabilities for application in the software development projects that become established on the platform (i.e., exploitation). The micro-dynamics of this system are studied empirically by constructing transition probability matrices representing the movements of 222,835 SF.net users among seven different activity states, which range from ""lurking"" (not contributing or contributing to projects without becoming a member) to ""laboring"" (joining one or more projects as members), and to ""launching"" (founding one or more projects) within each successive 6-month interval. The estimated probabilities are found to form first-order Markov chains describing ergodic processes. This makes it possible the computation of the equilibrium distribution of agents among the states, thereby suppressing transient effects and revealing persisting patterns of project joining and project launching. The latter show the FLOSS innovation process on SF.net to be highly dissipative: a very large proportion of the registered ""developers"" fail to become even minimally active on the platform. There is nevertheless an active core of mobile project joiners, and a (still smaller) core of project founders who persist in creating new projects. The structure of these groups' interactions (as displayed within the 3-year period examined) is investigated in detail, and it is shown that it would be sufficient to sustain both the exploration and exploitation phases of the platform's global dynamics.

Results of the experiments showed that exposure of A. flos-aquae to Ni caused the most toxic effect as compared to exposure with Fe and Mn. The 96 hr LC50 value for Ni exposure was 0.321 mu g/mL (approximately 30\\% inhibition), whereas Mn was the second most toxic metal followed by Fe with the 96 hr LC50 values of 0.684 mu g/mL and 3.020 mu g/mL respectively. This study demonstrated that even though Fe and Mn are essential micronutrients for A. flos-aquae, both show toxic effects at high concentrations. The difference in the toxicity value between Fe and Mn for A. flos-aquae is five times and this indicates that Mn was five times more toxic to A. flos-aquae than Fe suggestings that the cyanobacteria is more tolerant to Fe when compared with Mn.",NA

Successful development of such models will be important for decision makers of various kinds. We propose hypotheses based on a prior case study on manpower function and effort modeling. A large data set retrieved from a project repository is used to test these hypotheses. The main results are that if Norden-Rayleigh-based approaches are used, they need to be complemented in order to account for the addition of new features during a product life cycle, and that programmer-participation based effort models result in distinctly lower estimations of effort than those based on output metrics, such as lines of code.

+1715,Article,Evaluating the performance of open source software projects using data envelopment analysis,"The purpose of this paper is to develop and test a model of the relative performance of open source software (OSS) projects. This paper evaluates the relative performance of OSS projects by evaluating multiple project inputs and multiple project outputs by using a data envelopment analysis (DEA) model. The DEA model produces an efficiency score for each project based on project inputs and outputs. The method of producing an efficiency score is based on the convex envelopment technology structure. The efficiency measure quantifies a ""distance"" to an efficient frontier. The DEA model produced an index of corresponding intensities linking an inefficient project to its benchmark efficient project(s). The inefficiency measures produced an ordering of inefficient projects. Eight projects were found to be ""efficient"" and used as benchmarking projects. This research is limited to only security-based OSS projects. Future research on other areas of OSS projects is warranted. The result of this research is a practical model that can be used by OSS project developers to evaluate the relative performance of their projects and make resource decisions. An OSS project manger can effectively use these results to critically evaluate resources for their project and judge the relative efficiency of the resources.",10.1108/09685220810920530
+1717,Article,Explaining leadership in virtual teams: The case of open source software,"This paper contributes to the open source software (OSS) literature by investigating the likelihood that a participant becomes a project leader. Project leaders are key actors in a virtual community and are crucial to the success of the OSS model. Knowledge of the forces that lead to the emergence of project managers among the multitude of participants is still limited. We aim to fill this gap in the literature by analyzing the association between the roles played by an individual who is registered with a project, and a set of individual-level and project-level characteristics. In line with the theory of occupational choice elaborated by (Lazear, E.P., 2002. Entrepreneurship. NBER Working Paper No. 9109, Cambridge, Mass; Lazear, E.P., 2004. Balanced skills and entrepreneurship, American Economic Review 94, pp. 208-211), we find that OSS project leaders possess diversified skill sets which are needed to select the inputs provided by various participants, motivate contributors, and coordinate their efforts. Specialists, like pure developers, are endowed with more focused skill sets. Moreover, we find that the degree of modularity of the development process is positively associated with the presence of project leaders. That result is consistent with the modern theory of modular production (Baldwin, C.Y., Clark, K.B., 1997. Managing in an age of modularity.

Recent studies have shown that analyzing data from source code repositories is an efficient way to gather information about project characteristics and programmers, showing that OSS projects are very heterogeneous in their team structures and software processes. However, one problem is that the resulting process metrics measuring attributes of the development process and of the development environment do not give any hints about the quality, complexity, or structure of the resulting software. Therefore, we expanded the analysis by calculating several product metrics, most of them specifically tailored to object-oriented software. We then analyzed the relationship between these product metrics and process metrics derived from a CVS repository. The aim was to establish whether different variants of open source development processes have a significant impact on the resulting software products. In particular we analyzed the impact on quality and design associated with the numbers of contributors and the amount of their work, rising the GINI coefficient as a measure of inequality within the developer group.",10.4018/jdm.2008040102

With this unprecedented pace of innovation, comes new obligations. In this article the authors discuss the areas of governance, education, and tools which together constitute the base capabilities required for the effective enterprise adoption of F/LOSS technology and principles.

It is without doubt that an increasing number of software and hardware vendors are investing significant amounts in open Source software in a number of ways. This may be due primarily to the fact that open source ultimately produces greater value on both the use and production sides, implying an impact on welfare. This chapter attempts a holistic approach on the analysis of the OSS phenomenon and its impact on welfare. The main entities of the OSS ecosystem are identified and analysed under the scope of the main factors affecting welfare: innovation, competition and productivity. For that purpose an all encompassing model of the OSS ecosystem is created to reflect the interactions among its entities as well as the direct and indirect effects on welfare factors. Innovation and productivity are promoted by the accumulation of knowledge and human capital input by individuals as well as by enterprises. OSS as an innovative mode of production has created market opportunities and new sustainable business models, creating the appropriate conditions for new entrances and a raise in competition in the software market.

Open source software, on the other hand, allows its user access to source code, thereby allowing them to customize the software according to their needs and integrate it with existing software infrastructure: and, if need be, redistribute it. Open source software, therefore, has potential benefits for government agencies in terms of electronic service provision to general public.

+1754,Article,Online innovation: the case of open source software development,"Purpose - The aim of this paper is to investigate the role of online networking during the innovation process, including its role(s) in communication, cooperation and coordination. The paper neither implicitly assumes that online computer-based networking is a prerequisite for the innovation process nor denies the possibility that innovation can emerge and successfully survive without it. It merely presupposes that, in cases of innovation where information and communication technologies play a substantial role, non-proprietarity may offer an interesting alternative to innovations based on proprietary knowledge. Design/methodology/approach - The paper borrows from the theory of communities-of-practice, which takes into account social relations, contacts, and the transfer and incorporation of knowledge. Open source innovation is not the exclusive preserve of computer nerds, but also has implications for existing software manufacturers. The paper therefore includes the case of IBM, a company which has successfully integrated this new and more open way of collaboration into its business model. Findings - The paper concludes that online computer-based innovation fundamentally challenges current ways of communicating, cooperating and coordinating during the innovation and product development process. Moreover, it challenges the traditional business model in that it forces the actors involved to shift the focus from the innovation itself to the identification of new supporting services higher up the value chain. Last, but not least, it blurs the boundary between development and use, since the developer remains the key user. Research limitations/implications - The paper addresses the implications for future research in the area. Practical implications - The paper addresses implications for practitioners directly involved in innovation and product development. Originality/value - This paper develops a conceptual framework for understanding product development based on non-proprietary knowledge, which cannot be adequately accounted for by traditional corporate innovation theory alone.",10.1108/14601060810845268

Few resources for healthcare, geographical and infrastructure issues, lack of trained staff, language and cultural diversity and political instability all affect the ability of health providers to support effective and efficient healthcare. Health information systems are a key aspect of improving healthcare, but existing systems are often expensive and unsuitable. Open source software appears to be a promising avenue for quickly and cheaply introducing health information systems that are appropriate for developing nations. This article describes some aspects of open source e-health software that are particularly relevant to developing nations, issues and problems that may arise and suggests some future areas for research and action. Suggestions for critical success factors are included. Much of the discussion will be related to a case study of a training and e-health project, currently running in the Himalayan kingdom of Bhutan.",10.4018/jhisi.2008070101

The development of new separation techniques, precise mass analyzers and experimental protocols is a very active field of research. This leads to more complex experimental setups yielding ever increasing amounts of data. Consequently, analysis of the data is currently often the bottleneck for experimental studies. Although software tools for many data analysis tasks are available today, they are often hard to combine with each other or not flexible enough to allow for rapid prototyping of a new analysis workflow. Results: We present OpenMS, a software framework for rapid application development in mass spectrometry. OpenMS has been designed to be portable, easy-to-use and robust while offering a rich functionality ranging from basic data structures to sophisticated algorithms for data analysis.

The standardized seasonal rainfall Shows all autumn trend that approximates the annual trend With amplitude of live years, while rainfall during the winter declines and inclines during above the long-term average during spring. Concurrently, sodium, sulfate and chloride soil concentrations increased rapidly in the late 1990s, together with increases ill the very fine sand fraction, which reflects the active erosion and deposition processes associated with recent human interference. There is a general process of recharging plant species diversity (long-term records; 122 perennials and 104 annuals) in the late 1990s following a sizeable decline; 26 perennials with declining density and spatial occupation call be considered at threat. Some of these species are transient and show a three-year cycle of species replacement (turnover when related to added species).

To begin with, the article defines the term ``source code{''} in reference to software{''} and it also explains the terms ``open source{''} and ``free software.{''} Moreover, it introduces the definition of Free/Open-Source Software (FOSS). In the following part of the article, Konat offers a microeconomic analysis of ``strategic forking{''} to determine the motives guiding software engineers taking part in FOSS projects. The problem is discussed from the perspective of the theory of public goods, the demand-side approach to innovation, and other theories concerned with issues such as ``hackers' ethic{''} and ``ego boosting.{''} Konat pays special attention to describing the ``strategic forking{''} phenomenon with the use of classical microeconomic and enterprise theory tools developed by researchers Jean Tirole and Josh Lerner. The author follows up with a comprehensive analysis of strategic forking as a key to explaining a fundamental discrepancy in the assessment of the motives that guide programmers taking part in the development of open-source software. The analysis focuses on the definition of strategic forking, the conditions determining this trend and its direct causes. Konat also looks at the implications of strategic forking and the factors due to which this approach has not become more widespread around the world.

This chapter uses coordination theory to analyze the bug fixing processes in the proprietary operating system development group of a large minicomputer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel. Three approaches to identifying dependencies and coordination mechanisms are presented. Mechanisms analyzed include those for task assignment, resource sharing, and managing dependencies between modules of source code. The proprietary development organization assigned problem reports to engineers based on the module that appeared to be in error, because engineers only worked on particular modules. Alternative task assignment mechanisms include assignment to engineers based on workload or voluntary assignment, as in Linux. In the proprietary process, modules of source code were not shared but, rather, were ``owned{''} by one engineer, thus reducing the need for coordination. In Linux, where multiple developers can work on the same modules, alternative resource sharing mechanisms have been developed to manage source code. Finally, the proprietary developers managed dependencies between modules informally, relying on their personal knowledge of which other engineers used their code. The Linux process allows developers to change code in multiple modules, but emphasizes modularity to reduce the need to do so. By helping in the identification of dependencies in the bug fixing processes, drawing upon coordination theory streamlines bug fixing activities of a large mini-computer manufacturer and for the Free/Libre Open Source Software Linux operating system kernel.",NA

Unfortunately this goal has not been achieved mainly due to a lack of both tools and data management, as data must be gathered from different sources and in different formats. Compounding this problem is the fact that in some regions different water agencies are in charge of water supply as is the case in the Basin of Mexico, in which Mexico City and its Metropolitan Zone are located. The inhabitants of the Basin of Mexico, which comprises five different political entities and in which different agencies are in charge of water supply rely on the Basin's aquifer system as its main water supply source. However, a regional hydrogeological database in this area does not exist which is why the use of both a Relational Database Management System (RDMBS) and a Geographic Information System (GIS) is proposed in order to improve regional data management in the study area. Data stored in this new database, the Basin of Mexico Hydrogeological Database (BMHDB) comprise data on climatological, borehole and run-off variables, readily providing information for the development of hydrogeological models. A simple example is used to show how geostatistical analysis can be done using the data directly from the BMHDB. The structure of the BMHDB allows easy maintenance and updating, representing a valuable tool for the development of regional studies. (c) 2008 Elsevier Ltd.

Gathering and maintaining large F/OSS data collections reliably and making them usable present several research challenges. For example, current projects usually rely on direct access to, and mining of raw data from groups that generate it, and both of these methods require unique effort for each new corpus, or even for updating existing corpora. In this paper, we identify several needs and critical factors in F/OSS empirical research across disciplines, and suggest recommendations for design of a global research infrastructure for multi-disciplinary research into F/OSS development.",NA
+1812,Article,Understanding knowledge sharing activities in free/open source software projects: An empirical study,"Free/Open Source Software (F/OSS) projects are people-oriented and knowledge intensive software development environments. Many researchers focused on mailing lists to study coding activities of software developers. How expert software developers interact with each other and with non-developers in the use of community products have received little attention. This paper discusses the altruistic sharing of knowledge between knowledge providers and knowledge seekers in the Developer and User mailing lists of the Debian project. We analyze the posting and replying activities of the participants by counting the number of email messages they posted to the lists and the number of replies they made to questions others posted. We found out that participants interact and share their knowledge a lot, their positing activity is fairly highly correlated with their replying activity, the characteristics of posting and replying activities are different for different kinds of lists, and the knowledge sharing activity of self-organizing Free/Open Source communities could best be explained in terms of what we called ``Fractal Cubic Distribution{''} rather than the power-law distribution mostly reported in the literature. The paper also proposes what could be researched in knowledge sharing activities in F/OSS projects mailing list and for what purpose. The research findings add to ` our understanding of knowledge sharing activities in F/OSS projects. (C) 2007 Elsevier Inc. All rights reserved.",10.1016/j.jss.2007.03.086

Traditionally, research in OSS has focused on identifying individual personal motives for participating in the development of an OSS project, analyzing specific OSS solutions, or the OSS movement, itself. Nevertheless, user acceptance towards this type of technology has received very little attention. For this reason, the main purpose of the current study is to identify the variables and factors that have a direct effect on individual attitude towards OSS adoption. Therefore, we have developed a technological acceptance model on behalf of the users towards a solution based on OSS. For this development, we have considered the technology acceptance model. Findings show that OSS is a viable solution for information management for organizations. (C) 2007 Elsevier Ltd. All rights reserved.",10.1016/j.chb.2007.10.006
+1814,Article,User and developer mediation in an Open Source Software community: Boundary spanning through cross participation in online discussions,"The aim of this research is to analyse how design and use are mediated in Open Source Software (OSS) design. Focusing on the Python community, our study examines a ``pushed-by-users{''} design proposal through the discussions occurring in two mailing-lists: one, user-oriented and the other, developer-oriented. To characterize the links between users and developers, we investigate the activities and references (knowledge sharing) performed by the contributors to these two mailing-lists. We found that the participation of users remains local to their community. However, several key participants act as boundary spanners between the user and the developer communities. This emerging role is characterized by cross-participation in parallel same-topic discussions in both mailing-lists, cohesion between cross-participants, the occupation of a central position in the social network linking users and developers, as well as active, distinctive and adapted contributions. The user championing the proposal acts as a key boundary spanner coordinating the process and using explicit linking strategies. We argue that OSS design may be considered as a form of ``role emerging design{''}, i.e. design organized and pushed through emerging roles and through a balance between these roles. The OSS communities seem to provide a suitable socio-technical environment to enable such role emergence. (C) 2007 Elsevier Ltd. All rights reserved.",10.1016/j.ijhcs.2007.10.008
+1815,InProceedings,Using open source software in simulation: the IDF GF Battle Lab experience,"One of the major challenges the Israel Defense Forces (IDF) Ground Forces (GF) Battle Lab (BL) has been facing in recent years is the introduction of new simulation technologies and methods, under tight development schedule constraints. Introducing new technologies requires a ""proof of concept"" process in order to decide on the profitability of further development. Using Open Source software solutions in the BL helped make this process quicker and more efficient.The BL has been developing its proprietary Computer Generated Forces (CGF) for approximately 10 years. This CGF is mainly intended for simulating ground entities and has various capabilities for autonomous movement. Over the years, as the visual systems have improved and due to the introduction of urban environments simulation, the need for realistic movement characteristics, especially human, became important. An in-house solution, developed by the CGF team, appeared to consume too much development effort and was not extendable enough. After analyzing the problem and reviewing various third-party solutions, the CGF team decided on using an Open Source (OS) library called OpenSteer.Until recently, ground vehicle simulations in the BL used a low fidelity non-physical movement mode, based on ground clamping. In 2006 the BL got involved in research areas related to Unmanned Ground Vehicles (UGVs) and human-robotics interactions. During early research stages it became clear that it would be necessary to simulate the UGV dynamics in higher fidelity than was done before. The development team decided to initiate the ""proof of concept"" process before full scale development. Therefore a quick solution for a high-fidelity vehicle simulation was searched for. After a brief review of third party solutions, an OS library, Open Dynamics Engine (ODE) was chosen. Developing a UGV simulation required an autonomous movement model which appeared to have similar characteristics to the one developed by the CGF team based on OpenSteer. Since OpenSteer was not originally intended for simulating rigid-body vehicles, the development team faced the challenge of integrating both products, OpenSteer and ODE. This paper will describe the steps taken in order to assimilate OS products in the BL simulation test-bed and lessons learned.",NA

The study objective was to validate two complementary indicators, i.e., the OIDP (Oral Impacts on Daily Performances) and Oral Satisfaction 0-10 Scale (OSS), in two qualitatively different socio-demographic samples of the Spanish adult population, and to analyse the factors affecting both perspectives of well-being. Methods: A cross-sectional study was performed, recruiting a Validation Sample from randomly selected Health Centres in Granada (Spain), representing the general population (n = 253), and a Working Sample (n = 561) randomly selected from active Regional Government staff, i. e., representing the more privileged end of the socio-demographic spectrum of this reference population. All participants were examined according to WHO methodology and completed an inperson interview on their oral impacts and oral satisfaction using the OIDP and OSS 0-10 respectively. The reliability and validity of the two indicators were assessed. An alternative method of describing the causes of oral impacts is presented. Results: The reliability coefficient (Cronbach's alpha) of the OIDP was above the recommended 0.7 threshold in both Validation and Occupational samples (0.79 and 0.71 respectively). Test-retest analysis confirmed the external reliability of the OSS (Intraclass Correlation Coefficient, 0.89; p < 0.001) Some subjective factors (perceived need for dental treatment, complaints about mouth and intermediate impacts) were strongly associated with both indicators, supporting their construct and criterion validity. The main cause of oral impact was dental pain. Several socio-demographic, behavioural and clinical variables were identified as modulating factors. Conclusion: OIDP and OSS are valid and reliable subjective measures of oral impacts and oral satisfaction, respectively, in an adult Spanish population. Exploring simultaneously these issues may provide useful insights into how satisfaction and impact on well-being are constructed.",10.1186/1477-7525-6-101

+1832,Article,"Sexual Selection, Automata and Ethics in George Eliot's The Mill on the Floss and Olive Schreiner's Undine and From Man to Man","This paper brings together two related areas of debate in the latter half of the nineteenth century. The first concerns how the courtship plot of the nineteenth-century novel responded to, and helped to shape, scientific ideas of sexual competition and selection. In The Mill on the Floss (1860), George Eliot strikingly prefigures Darwin's later work on sexual selection, drawing from her own extensive knowledge of the wider debates within which evolutionary theory developed. Maggie Tulliver's characterisation allows Eliot to explore the ethical complexities raised by an increasingly powerful scientific naturalism, where biology is seen to be embedded within morality in newly specific ways. The second strand of the paper examines the extension of scientific method to human mind and motivation which constituted the new psychology. It argues that there are crucial continuities of long-established ethical and religious ideas within this increasingly naturalistic view of human mind and motivation. The contention that such ideas persist and are transformed, rather than simply jettisoned, is illustrated through the example of Thomas Henry Huxley's 1874 essay on automata. Turning finally to focus on Olive Schreiner's Undine (1929) and From Man to Man (1926), the paper explores the importance of these persistent ethical and religious ideas in two novels which remained unpublished during her lifetime. It argues that they produce both difficulty and opportunity for imagining love plots within the context of increasingly assertive biological and naturalistic accounts of human beings.",10.3366/E1355550209000587

This paper examines how commodity computation, communication, and measurement products combined with open-source analysis and communication applications can be incorporated into laboratory medicine microbiology protocols. Those commodity components are all now sourceable globally. An informatics model is presented for guiding the use of low-cost commodity components and free software in the assembly of clinically useful and usable telemicrobiology workstations. Methods: The model incorporates two general principles: 1) collaborative diagnostics, where free and open communication and networking applications are used to link distributed collaborators for reciprocal assistance in organizing and interpreting digital diagnostic data; and 2) commodity engineering, which leverages globally available consumer electronics and open-source informatics applications, to build generic open systems that measure needed information in ways substantially equivalent to more complex proprietary systems. Routine microscopic examination of Giemsa and fluorescently stained blood smears for diagnosing malaria is used as an example to validate the model. Results: The model is used as a constraint-based guide for the design, assembly, and testing of a functioning, open, and commoditized telemicroscopy system that supports distributed acquisition, exploration, analysis, interpretation, and reporting of digital microscopy images of stained malarial blood smears while also supporting remote diagnostic tracking, quality assessment and diagnostic process development. Conclusion: The open telemicroscopy workstation design and use-process described here can address clinical microbiology infrastructure deficits in an economically sound and sustainable manner. It can boost capacity to deal with comprehensive measurement of disease and care outcomes in individuals and groups in a distributed and collaborative fashion. The workstation enables local control over the creation and use of diagnostic data, while allowing for remote collaborative support of diagnostic data interpretation and tracking. It can enable global pooling of malaria disease information and the development of open, participatory, and adaptable laboratory medicine practices. The informatic model highlights how the larger issue of access to generic commoditized measurement, information processing, and communication technology in both high-and low-income countries can enable diagnostic services that are much less expensive, but substantially equivalent to those currently in use in high-income countries.",10.1186/1475-2875-8-164

In this paper, the software evolution process is analyzed using a proposed Evolution curve (E-curve) method, which is based on information theoretic metrics of source code. The method allows identifying major evolution stages and transition points of an analyzed software system. The application of the E-curves is demonstrated for the eMule system.",10.3233/978-1-58603-939-4-205
+1858,Article,"Antecedents of open source software defects: A data mining approach to model formulation, validation and testing","This paper develops tests and validates a model for the antecedents of open source software (OSS) defects, using Data and Text Mining. The public archives of OSS projects are used to access historical data on over 5,000 active and mature OSS projects. Using domain knowledge and exploratory analysis, a wide range of variables is identified from the process, product, resource, and end-user characteristics of a project to ensure that the model is robust and considers all aspects of the system. Multiple Data Mining techniques are used to refine the model and data is enriched by the use of Text Mining for knowledge discovery from qualitative information. The study demonstrates the suitability of Data Mining and Text Mining for model building. Results indicate that project type, end-user activity, process quality, team size and project popularity have a significant impact on the defect density of operational OSS projects. Since many organizations, both for profit and not for profit, are beginning to use Open Source Software as an economic alternative to commercial software, these results can be used in the process of deciding what software can be reasonably maintained by an organization.",10.1007/s10799-009-0062-5

We found that key factors for not adopting an open source solution were closely linked to the orientations of ministry level policy makers and a seeming lack of information on the part of operational level IT managers concerning commercially oriented open source providers. We use the case of recent changes in the structure of Quebec's health care organizations and a change in the commercial policies of a key vendor to illustrate our conclusions regarding barriers to adoption of open source products.,10.1007/s10916-008-9158-4

As such, they often leverage not only open-source software, but also some proprietary solutions which, although closed source, may not command a licence fee. This paper briefly discusses an undergraduate project addressing a hardware solution integrating several open-source software projects into a cohesive structure. The platform, tentatively dubbed as a “Mobile ISP” – or mISP is a natural extension on the established Wireless ISP concept with a practical bent towards wire-free deployment and gateway connectivity.

Thus the existing software systems must evolve to conform to these requirements. The model which currently address this kind of concern is SOA (Service Oriented Architecture). This article deals with the reuse of ADempiere within the framework of the implementation of a service oriented ERP. To operate the migration of the existing code, firstly we reconstituted the architecture of this ERP. This operation made it possible to acquire the technical knowledge necessary to develop services by injection of dependence. The new software resulting from this operation distinctly separates the presentation tier from the back-end. The back-end tier exposes a set of Web services which encapsulates the code of ADempiere. These services can either be in a synchronous way throughout the Spring XFire technology, or in an asynchronous way through Apache ActiveMQ technology.",10.1109/ICSEA.2009.14

The objective of this research is to empirically examine the Brooks' Law in a Free Software context. The principle is separated out into its two primary premises: the first is based on a developer's ability to become productive when joining a new team; the second premise relates to the quality of coordination as the team grows. Three large projects are studied for this purpose: KDE, Plone and Evince. Based on empirical evidence, the paper provides two main contributions: based on the first premise of Brooks' Law, it claims that coordination costs increase only in a very specific phase for Free Software projects. After that, these costs become quasi-constant. Secondly, it shows that a ramp up period exists in Free Software projects, and this period marks the divide between projects that are successful at engaging new contributors from others that only benefit from occasional new contributors.",10.1109/ICSM.2009.5306308

Research in the area of customization of OSS is rare, however. The process after the deployment of an OSS within a company remains unknown. There is a danger that it is often unstructured and error-prone since OSS develops in a more complex way than proprietary software. Based on our literature study, modifications of open source code do occur also in organizations outside of the software industry. Customization of applications is more common than customization of infrastructure software in these organizations. Therefore, we examine the process of deployment and adaptation of an OSS application software over several update iterations in great detail. This examination shows that this process has similarities with the process of deployment of proprietary software but it also exhibits important differences. Based on this case study, we also suggest a process model for customization of OSS applications in user organizations.",NA

The Digital Video Broadcast Return Channel Satellite (DVB-RCS) NetOps vision for remote management and monitoring aims to provide visibility and Situational Awareness to required communities of interest as well as the ability to view and configure all the operational layers DVB-RCS, including the devices and technology, operations and management, and missions and objectives. An effective management and monitoring solution for DVB-RCS must provide the capability to centrally manage and monitor the system, interoperate between SATCOM and terrestrial networks, consolidate technology, standardize processes, and be proactive rather than reactive. The DISN OSS is DISA's enterprise-wide Service Oriented Architecture for information sharing, management, and monitoring capabilities, based on the Telecommunications Management Network industry standards. The DISN OSS puts the information into the hands of the operators and system managers while making the processes, tools, and technology transparent to the consumer. This paper examines how DVB-RCS implemented the NetOps Portal as an immediate and interim solution to provide Situational Awareness to CENTCOM, as well as how leveraging the DISN OSS can help DVB-RCS achieve assured system and network availability, assured information protection, and assured information delivery in support of high-bandwidth, two-way services for the tactical Warfighter.",NA
+1873,Article,Decon2LS: An open-source software package for automated processing and visualization of high resolution mass spectrometry data,"Background: Data generated from liquid chromatography coupled to high-resolution mass spectrometry (LC-MS)based studies of a biological sample can contain large amounts of biologically significant information in the form of proteins, peptides, and metabolites. Interpreting this data involves inferring the masses and abundances of biomolecules injected into the instrument. Because of the inherent complexity of mass spectral patterns produced by these biomolecules, the analysis is significantly enhanced by using visualization capabilities to inspect and confirm results. In this paper we describe Decon2LS, an open-source software package for automated processing and visualization of high-resolution MS data. Drawing extensively on algorithms developed over the last ten years for ICR2LS, Decon2LS packages the algorithms as a rich set of modular, reusable processing classes for performing diverse functions such as reading raw data, routine peak finding, theoretical isotope distribution modelling, and deisotoping. Because the source code is openly available, these functionalities can now be used to build derivative applications in relatively fast manner. In addition, Decon2LS provides an extensive set of visualization tools, such as high performance chart controls. Results: With a variety of options that include peak processing, deisotoping, isotope composition, etc, Decon2LS supports processing of multiple raw data formats. Deisotoping can be performed on an individual scan, an individual dataset, or on multiple datasets using batch processing. Other processing options include creating a two dimensional view of mass and liquid chromatography (LC) elution time features, generating spectrum files for tandem MS data, creating total intensity chromatograms, and visualizing theoretical peptide profiles. Application of Decon2LS to deisotope different datasets obtained across different instruments yielded a high number of features that can be used to identify and quantify peptides in the biological sample. Conclusion: Decon2LS is an efficient software package for discovering and visualizing features in proteomics studies that require automated interpretation of mass spectra. Besides being easy to use, fast, and reliable, Decon2LS is also open-source, which allows developers in the proteomics and bioinformatics communities to reuse and refine the algorithms to meet individual needs.

+1884,Article,Determinants of success in open source software networks,"Purpose - Open source software (OSS) products have rapidly acquired a notable importance in the last years among consumers and firms all over the world. They are mostly developed and distributed through online social networks thanks to the voluntary and collaborative actions of their members. However, their innovation and development has to face up the existence of free-riders which can benefit from the knowledge developed in the online social network. This paper aims to understand the factors that moderate the opportunistic behaviour in OSS development and distribution, which will help to correctly manage the OSS innovations. Design/methodology/approach - The influence of reputation on members' satisfaction and participation intentions in OSS online social networks are measured. Additionally, the impact of being an active and satisfied member on his/her commitment and intention to use the OSS products are studied. After the validation of measurement scales the hypotheses are contrasted with structural modelling. Findings - This research show that perceived reputation acts as a deterrent factor of free-riders. More specifically, reputation exerts a positive and significant effect on member's satisfaction with previous interactions and an indirect effect on participation intentions in the social network through satisfaction. Besides, these two outcomes of reputation boost the members' affective commitment to the OSS and, as a consequence, the intention to use OSS products is also increased. Practical implications - Reputation and satisfaction are two crucial aspects in explaining the success of an online social network since they serve to guarantee the interaction among its members. In addition, participation continuance intentions in an online network may help to increase the levels of affective commitment and loyalty to the mutual interest of the network (the OSS in this case). This result may be especially relevant for commercial networks, which are based on the admiration to a brand, firm or product. Originality/value - The analysis of online social networks as a development and distribution channel and the role of reputation in promoting members' participation (that is, avoiding opportunistic behaviour) represent a new contribution to the analysis of online social networks. This research field has acquired a notable popularity in recent years.",10.1108/02635570910948650

In order to detect types, and establish similarities, among Free/Libre/Open Source Software (FLOSS) systems, this paper considers three modular characteristics (functions, files and folders) and their evolution: how they are evolving with size, if they are constant across systems, and whether recurring evolutionary patterns are observed. Using these various-grained characteristics, a set of models for the evolution of modularization are extracted from evolving systems, and then used to extract similarities and types from a wide sample of FLOSS projects. This paper provides three contributions: first, it shows that several models are needed to encompass the variety of modularization patterns; second, it provides three types of models (uni-variate, bi-variate and tri-variate) for the evolution of modularization, with significant goodness-of-fit's. Finally, it shows that two of these patterns alone can interpolate the modular characteristics of the vast majority of a random choice of FLOSS projects.",NA

+1903,Article,Firms' contribution to open-source software and the dominant user's skill,"Free, libre or open-source software (FLOSS) is nowadays produced not only by individual benevolent developers but, in a growing proportion, by firms that hire programmers for their own objectives of development in open source or for contributing to open-source projects in the context of dedicated communities. A recent literature has focused on the question of the business models explaining how and why firms may draw benefits from such involvement and their connected activities. They can be considered as the building blocks of a new modus operandi of an industry, built on an alternative approach to intellectual property management. Its prospects will depend on both the firms' willingness to rally and its ability to compete with the traditional `proprietary' approach. As a matter of fact, firms' involvement in FLOSS, while growing, remains very contrasted, depending on the nature of the products and the characteristics of the markets. This paper asks why for-profit firms contribute to FLOSS development and why some firms contribute more than others. The common explanation is that FLOSS is often a complement to proprietary software (or hardware or services) that the for-profit firm sells at a positive price. We present an alternative explanation based on the users' skill level. When users are skilled, opening the software is likely to result in a better product because the user base will contribute improvements (find bugs, write fixes and produce new features). We introduce the concept of the dominant user's skill and set up a theoretical model to better understand how it may condition the nature and outcome of the competition between a FLOSS firm and a proprietary firm. We discuss these results in the light of stylized facts drawn from recent trends in the software industry. European Management Review (2009) 6, 130-139. doi:10.1057/emr.2009.8",10.1057/emr.2009.8

Principles of openness, truth, freedom and progress, which are also understood as central to the technical production of good software, are reinforced (as a ethical orientation) by their contribution to making `good' software. A reciprocal dynamic ensues in which better software is seen as dependent on particular social practices and ideologies while these practices and ideologies are given salience by their success in fostering valuable production. Processes key to the generation of this social form are examined before a number of key features of the practice of programming, such as its often combative and individualistic character, and an absence of women in developer communities, are considered in the light of the analysis.",10.1080/00141840902751188

A key paradox of the global Internet is that it allows individual and collective decision making to co-exist with each other. Open source software (OSS) communities are a globally accelerating phenomenon. OSS refers to groups of programs that allow the free use of the software and further the code sharing to the general and corporate users of the software. The combination of private provision and public knowledge and software, and the seeming paradox of economic versus social motivations have stimulated a wide debate between researchers and policymakers. In this article, we analyze OSS communities from the viewpoint of ``intrinsic motivation,{''} knowledge creation, and collective Internet governance. We believe that the growth of global OSS has fundamental implications for business ethics and the governance of the global Internet in the twenty-first century.",10.1007/s10551-009-0057-5

Being a functional structural model, its software implementation and test are costly. On the other hand, software is a necessary tool to understand, analyze and apply the model. With increasing scientific publications on Green Lab, need for a freely-accessible software increased in the community of plant modeling. Implementation of Green Lab has been done in Scilab, named Green Scilab, which simulates generic plant structures from trees to crops. In this paper, a new version of GreenScilab dedicated to herbaceous plants, called GreenScilab-Crop, is presented. It allows flexible control on plants, especially the position-dependent organ growth delay. A case study is made on tomato plant for simulation and parameter identification.",NA

This paper considers how Free/libre Open Source Software (FLOSS) teams demonstrate such behaviors within the context of e-mail, as this is the primary medium through which such teams communicate. We compare group maintenance behaviors between both core and peripheral members of these groups, as well as behaviors between a group that remains producing software today and one which has since dissolved. Our findings indicate that negative politeness tactics (those which show respect for the autonomy of others) may be the most instrumental group maintenance behaviors that contribute to a FLOSS group's ability to survive and continue software production.",NA
+1920,Article,Identifying exogenous drivers and evolutionary stages in FLOSS projects,"The success of a Free/Libre/Open Source Software (FLOSS) project has been evaluated in the past through the number of commits made to its configuration management system, number of developers and number of users. Most studies, based on a popular FLOSS repository (SourceForge). have concluded that the vast majority of projects are failures. This Study's empirical results confirm and expand conclusions from an earlier and more limited work. Not only do projects from different repositories display different process and product characteristics, but a more general pattern can be observed. Projects may be considered as early inceptors in highly visible repositories, or as established projects within desktop-wide projects, or finally as structured parts of FLOSS distributions. These three possibilities ire formalized into a framework of transitions between repositories. The framework developed here provides a wider context in which results from FLOSS repository mining can be more effectively presented. Researchers can draw different conclusions based on the overall characteristics studied about an Open Source software project's potential for success, depending on the repository that they mine. These results also provide guidance to OSS developers when choosing where to host their project and how to distribute it to maximize its evolutionary success. (C) 2008 Elsevier Inc.

The sample of open source projects includes all mature projects driven by the Eclipse Foundation as of February 2008. Three types of project diversity were used: i) organizational - measured by number of committers per organization per project, ii) contribution - measured by the number of commits made per organization per project, and iii) technical - measured by the number of commits made per given software file type. Success was measured by means of i) economic metrics, including the number of corporate adoptions and the number of jobs postings including the project name, and ii) development metrics, including the project popularity and the growth of the intensity of members' activity. The paper makes two main contributions. First, we contribute to the literature on open source software and diversity.

Decision-making power is gained through proven competence and activity in the project, and non-technical end-user opinions are too many times neglected. In addition, also human-computer interaction (HCI) specialists have encountered difficulties in trying to participate in OSS projects, because there seems to be no clear authority and responsibility for them. In this paper, based on HCI and OSS literature, we introduce an extended OSS development project organization model that adds a new level of communication and roles for attending human aspects of software.

This paper reviews relevant literature related to international operations of knowledge-intensive firms, especially in the software industry. Theoretical development is based here on a combination of the network approach, international new venture theory and inward-outward internationalization. The findings in this study suggest that the international activities of OSS firms can be divided into project activities and business activities. Project activities include inward and outward linkages, and partner identification. Business activities include domestic and partner network activities that can lead to international business as well. For scholars, the framework provides a new approach to explain many international activities of OSS firms by integrating three international business theories. In addition, it provides good starting point for further empirical examination. The framework helps managers gain a better understanding of complex circumstances embedded into the international activities of OSS firms. With that better understanding, the managers can focus their activities, which helps further to improve their firms' competitiveness engendered by the international activities in the OSS development. The framework developed in this study is believed to be the first serious attempt to provide a deeper theoretical understanding of international activities of OSS firms.

Organizations are also now adopting open source software, despite some reservations in particular regarding the provision and availability of support. One of the greatest concerns about free and open source software is the availability of post release support and the handling of for support. A common belief is that there is no appropriate support available for this class of software, while an alternative argument is that due to the active involvement of Internet users in online forums, there is in fact a large resource available that communicates and manages the management of support requests. The research model of this empirical investigation establishes and studies the relationship between open source software support requests and online public forums. The results of this empirical study provide evidence about the realities of support that is present in open source software projects.

Another approach to increase productivity and experience significant cost savings is to utilize Open Source (OS) components in software development. This paper presents the state of the art of how to combine MDD methods with OS software development. The approach is called Open Models software development which is expected to combine the benefits of both worlds. The fundamental idea of Open Models development is to apply community-driven collaborative MDD. In this paper, Open Models development is exemplified by constructing Resource Availability Service (RAS).

The primary difficulty is that software development efforts are complex in terms of both the technical and social aspects of the engineering environment. This is compounded by the lack of real data that captures both the measures of success in performing a process, and the measures that reflect a group's social dynamics. This research focuses on the development of a model for predicting software project success that leverages the wealth of available open source project data in order to accurately forecast the behavior of those software engineering groups. The model accounts for both the technical elements of software engineering and the social elements that drive the decisions of individual developers. Agent-based simulations are used to represent the complexity of the group interactions, and the behavior of each agent is based on the acquired open source software engineering data. For four of the five project success measures, the results indicate that the developed model represents the underlying data well and provides accurate predictions of open source project success indicators.",10.1145/1540438.1540461

However, there is little research exploring the interactions between open source stakeholders and the platform. We believe that the sustainability of the platform crucially depends on financial incentives. While platforms can obtain these incentives through multiple means, in this paper we focus on one form of financial incentives-voluntary monetary donations by open source community members. We report findings from two empirical studies that examine factors that impact donations. Study I investigates the factors that cause some community members to donate and not others. We find that the decision to donate is impacted by relational commitment with open source software platform, donation to projects and accepting donations from others. Study 2 examines what drives the level of donation. We find that the length of association with the platform and relational commitment affects donation levels.

+1954,Article,OPEN SOURCE SOFTWARE: THE ROLE OF MARKETING IN THE DIFFUSION OF INNOVATION,"Much of the literature on open source software (OSS) has focused on the role of the community of users and developers as the primary driver of OSS growth. This focus on growth generated by the community is referred to as ``single factor{''} growth and is an assumption shared by literature on the diffusion of innovation. The purpose of this research is to attempt to fit a logistic model to a well-known OSS project as a confirmatory exercise supporting the use of a single factor growth model as suggested by the literature. The results show that a logistic model, or any kind of single factor model, is inadequate to describe the diffusion of the OSS project. The paper then explains conceptually and illustrates mathematically why single factor models cannot fully represent the diffusion of any OSS project. A well-known two-factor model drawn from the marketing literature is presented, shown to solve the problem of single factor models, and used to illustrate the importance of marketing in OSS projects. This research suggests that the OSS literature may be overemphasizing the importance of the size of the user and developer community during the initial stages of growth and that during these stages the diffusion of the OSS project is primarily driven by external forces such as advertising or marketing efforts.",NA

This study considers if it is possible from an organizational perspective for small to medium-sized cities to provide services and conduct business using only open source software (OSS). We examine characteristics of municipal government that may influence the adoption of OSS for the delivery of services and to conduct city business. Three characteristics are considered to develop an understanding of city behavior with respect to OSS: capability, discipline, and cultural affinity. Each of these general characteristics contributes to the successful adoption and deployment of OSS by cities. Our goal was to determine the organizational characteristics that promote the adoption of OSS. We conducted a survey to support this study resulting in 3316 responses representing 1286 cities in the Unites States and Canada.

Such methods are used, for example, in the spatio-temporal coding and processing of sensory information. However, the data generated by optophysiological methods must be processed carefully if relevant results are to be obtained. The raw fluorescence data must be digitally filtered and analyzed appropriately to obtain activity maps and fluorescence time course for single spots.

Studying OSS is of particular interest: (1) to investigate socio-technical settings supporting user participation to the design process, which is considered to be the major strength of OSS design; (2) to gain insights into supporting the changing nature of the software industry, which is becoming more and more distributed and global, and which is thus increasingly making use of OSS design tools and methods. In this research, we characterized effective roles of participants, i.e. participation, on the basis of activities analysis in three online interaction spaces (discussion, documentation and implementation) during a continuous ``pushed-by-users{''} design process of the Python project. Participation is targeted through a methodology articulating: (1) structural analyses (organization of the discussions, regularity and involvement of participants, quotes-based social network) in usage-oriented and development-oriented mailing lists of the projects' discussion space; (2) actions to the code and documentation made by participants in the implementation and documentation spaces. Besides the importance of the users' contribution to the process, OSS design is fostered by some key-participants, the cross-participants, who act as boundary spanners between the developers and the users, helping them to go beyond some barriers to participation. These findings can be reinforced developing software to automate the structural analysis of discussions and actions to the code and documentation. (C) 2008 Elsevier B.V.

+1969,InProceedings,Reassessing Brooks' Law for the Free Software Community,"Proponents, of Free Software have argued that some of the most established software engineering principles do not fully apply when considered in an open, distributed approach. Among these principles, ``Brooks' Law{''} has been questioned in the Free Software context: large teams of developers, contrary to the law, will not need an increasingly growing number of communication channels. As advocates claim, this is due to the internal characteristics of the Free Software process: the high modularity of the code helps developers to work on comparted sections, without the need to coordinate with all other contriutors. This paper examines Brooks' Law in a Free Software context, and it studies the interaction of contributors to a large Free Software project, KDE. The network of interactions is analyzed and a summary term, the ``compaction{''}, is dynamically evaluated to test how the coordination mechanism evolves over time in the project. This paper argues that the claim of advocates holds true, but with limitations: in the KDE project, the few initial developers needed a significant amount of communication. The growth of KDE brought the need to break the number of overall communication channels to a significant extent. Finally, an established amount of 300 developers currently needs the same amount of communication as when the developers were only 10. We interpret this result by arguing that Brooks' Law holds true among the core developers of any large Free Software project.",NA

However, there has been no effort to systematically review the state of the practice of reporting empirical studies of OSS with respect to the recommended standards of performing and reporting empirical studies in software engineering. It is important to understand, how to report empirical studies of OSS in order to make them useful for practitioners and researchers. Research aim: The aim of our research is to gain insights in the state of the practice of reporting empirical studies of OSS in order to identify the gaps to be filled for improving the quality of evidence being provided for OSS. Method: To that end, we decided to systematically review the empirical studies of OSS. A total of 63 papers reporting empirical studies were selected from the four editions of the Proceedings of the International Conference on Open Source Systems. The data were extracted and synthesised from the selected papers for analysis. Results and conclusions: We have found that the quality of the reported OSS-related empirical studies needs to be significantly improved. Based on the results of our systematic review and general principles of reporting good empirical research, we present a set of guidelines for reporting OSS-related empirical studies. The suggested guidelines are expected to help the research community to improve the quality of reported studies.",NA

Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects' diffusion over the network.",10.1007/s00191-008-0125-5

In this paper, we investigate that facet of software using a configurable simulation framework as a basis. The framework uses `agents' to represent developers and models the costs associated with first comprehending and then applying necessary changes to a fictitious code base. It also considers agent `memory recall' of their own code as a fundamental part of the framework and the fact that, with higher numbers of developers, maintenance of a higher proportion of other developers' code (rather than their own) is an inevitable, yet realistic aspect. Through exploration of the results and data produced by the simulation. We are able to explore `desirable' features that are part of simulating software evolution; as a discussion of the issues raised by the framework, we provide a set of class data from four open-source systems by way of comparison and show that trends in those systems are comparable with results generated by the simulation. The paper thus provides evidence that we can use simulation tools to help model evolving systems, whether based on default settings or user-configurable settings.",10.1109/ASWEC.2009.36

A number of highly influential papers have argued that the self-fulfilling nature of (even false) theories provides the underlying mechanism through which economics has adversely shaped not just social science but also management practice and individual behavior. We question these arguments and argue that there are important boundary conditions to theories falsely fulfilling themselves, boundary conditions that have hitherto been unexplored in organizational research, and boundary conditions that question the underlying premises used by organizational scholars and social scientists to attack economics. We specifically build on highly relevant findings from social psychology, philosophy, and organizational economics to show how (1) objective reality and (2) human nature provide two important boundary conditions for theories (falsely or otherwise) fulfilling themselves. We also defend organizational economics, specifically the use of high-powered incentives in organizations, and argue that self-interest (rightly understood) facilitates in creating beneficial individual and collective and societal outcomes.

+1987,InProceedings,Software Engineering in Practice: Design and Architectures of FLOSS Systems,"Free/Libre/Open Source Software (FLOSS) practitioners and developers are typically also users of their own systems: as a result, traditional software engineering (SE) processes (e.g., the requirements and design phases), take less time to articulate and negotiate among FLOSS developers. Design and requirements are kept more as informal knowledge, rather than formally described and assessed. This paper attempts to recover the SE concepts of software design and architectures from three FLOSS case studies, sharing the same application domain (i.e., Instant Messaging). Its first objective is to determine whether a common architecture emerges from the three systems, which can be used as shared knowledge for future applications. The second objective is to determine whether these architectures evolve or decay during the evolution of these systems. The results of this study are encouraging: albeit no explicit effort was done by FLOSS developers to define a high-level view of the architecture, a common shared architecture could be distilled for the Instant Messaging application domain. It was also found that, for two of the three systems, the architecture becomes better organised, and the components better specified, as long as the system evolves in time.",NA

While the benefits resulting from network externality have been examined in the related literature, the effect of free offer on the diffusion of new software has not been formally analyzed. We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters. Our methodology is shown to be applicable for both fixed and dynamic pricing strategies.",10.2753/MIS0742-1222260307
+1989,InProceedings,Structural Complexity and Decay in FLOSS Systems: An Inter-Repository Study,"Past software engineering literature has firmly established that software architectures and the associated code decay over time. Architectural decay is, potentially, a major issue in Free/Libre/Open Source Software (FLOSS) projects, since developers sporadically joining FLOSS projects do not always have a clear understanding of the underlying architecture, and may break the overall conceptual structure by several small changes to the code base. This paper investigates whether the structure of a FLOSS system and its decay can also be influenced by the repository in which it is retained: specifically, two FLOSS repositories are studied to understand whether the complexity of the software structure in the sampled projects is comparable, or one repository hosts more complex systems than the other It is also studied whether the effort to counteract this complexity is dependent on the repository, and the governance it gives to the hosted projects. The results of the paper are two-fold: on one side, it is shown that the repository hosting larger and more active projects presents more complex structures. On the other side, these larger and more complex systems benefit from more anti-regressive work to reduce this complexity.",10.1109/CSMR.2009.37

This paper presents an approach to data collection by using aggregation of feeds published by the different tools of a software forge. To allow this aggregation, collected data is semantically reformatted into Semantic Web standards: RDF, DC, DOAP, FOAF and EvoOnt. Resulting data can then be processed, re-published or displayed to project members. This approach was used to implement a supervision module that is integrated into the PicoForge platform.

The research question addresses the evolutionary relationship between classes and attributes as well as the connection between those changes and refactorings.

Open Source Software (OSS) has becoming widely adopted by commercial, public and academic organisations. Currently, there is increasing interest and demand in the existing applications of OSS in all fields all over the world. OSS has increased in prominence in the last decade, mostly due to the success of well-known software organisations such as Apache, Mozilla, Linux and Guice. As these organisations have become more dependent on software, the effective management of Software Evolution (SE) becomes more critical to an organization’s success. Therefore, the provision of well-evolved OSS has become an urgent issue in these days and will be so in the future. Therefore, the major challenge in OSS is how to evolve its environment, especially improvements in the security and quality of these systems.

+1006,Article,The State and Profile of Open Source Software Projects in health and medical informatics,"Purpose: Little has been published about the application profiles and development patterns of open source software (OSS) in health and medical informatics. This study explores these issues with an analysis of health and medical informatics related OSS projects on SourceForge, a large repository of open source projects. Methodology: A search was conducted on the SourceForge website during the period from May 1 to 15, 2007, to identify health and medical informatics OSS projects. This search resulted in a sample of 174 projects. A Java-based parser was written to extract data for several of the key variables of each project. Several visually descriptive statistics were generated to analyze the profiles of the OSS projects. Results: Many of the projects have sponsors, implying a growing interest in OSS among organizations. Sponsorship, we discovered, has a significant impact on project success metrics. Nearly two-thirds of the projects have a restrictive license type. Restrictive licensing may indicate tighter control over the development process. Our sample includes a wide range of projects that are at various stages of development (status). Projects targeted towards the advanced end user are primarily focused on bio-informatics, data formats, database and medical science applications. Conclusion: We conclude that there exists an active and thriving OSS development community that is focusing on health and medical informatics. A wide range of OSS applications are in development, from bio-informatics to hospital information systems. A profile of OSS in health and medical informatics emerges that is distinct and unique to the health care field. Future research can focus on OSS acceptance and diffusion and impact on cost, efficiency and quality of health care. (C) 2009 Elsevier Ireland Ltd.

To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation.

Projects were characterized by project type, number and experience of developers, number of bugs, and bug resolution time. Our results provided evidence of virtual organizational learning in OSS development projects and support for several factors as determinants of performance. Team size was a significant predictor, with mid-sized project teams functioning best. Teams of three to seven developers exhibited the highest efficiency over time and teams of eight to 15 produced the lowest mean time for bug resolution. Increasing the percentage of bugs assigned to specific developers or boosting developer participation in other OSS projects also improved performance.

OSS/FS alternatives complicate an already complex information goods market plagued by piracy concerns. Although producer perspectives on software pricing and piracy controls have been addressed extensively, consumers' perspective and willingness to pay for commercial software is not very well understood. This paper empirically determines willingness to pay for a leading commercial software application (Microsoft Office) in the presence of an OSS/FS alternative. A contingent valuation approach is used to elicit willingness to pay for the application.

+1033,Article,YADE-OPEN DEM: an open-source software using a discrete element method to simulate granular material,"Purpose - YADE-OPEN DEM is an open-source software based on the discrete element method, (DEM) which uses object oriented programming techniques. The purpose of this paper is to describe the software architecture. Design/methodology/approach - The DEM chosen uses position, orientation, velocity and angular velocity as independent variables of simulated particles which are subject to explicit leapfrog time-integration scheme (Lagrangian method). The three-dimensional dynamics equations based on the classical Newtonian approach for the second law of motion are used. The track of forces and moments acting on each particle is kept at every time step. Contact forces depend on the particle geometry overlap and material properties. The normal, tangential and moment components of interaction force are included. Findings - An effort is undertaken to extract the underlying object oriented abstractions in the DEM. These abstractions are implemented in C++, conform to object oriented design principles and use design patterns. Based on that, a software framework is developed in which the abstractions provide the interface where the modelling methods can be plugged-in. Originality/value - The resulting YADE-OPEN DEM framework is designed in a generic way which provides great flexibility when adding new scientific simulation code. Some of the advantages are that numerous simulation methods can be coupled within the same framework while plug-ins can import data from other software. In addition, this promotes code improvement through open-source development and allows feedback from the community. However implementing such models requires that one adheres to the framework design and the YADE framework is a new emerging software.

Design/methodology/approach - Through an empirical, interpretive case study and a literature review utilising the metaphor of text in the analysis, this paper provides a refined conceptualisation of user participation in OSS development. Findings - The paper reveals that different kinds of meanings have been attached to users and to their participation. User participation is both direct and indirect in the OSS development context. Some user groups actively take part in OSS development, while others are merely represented in it. Different kinds of intermediaries ``representing the users{''} are identified. Research limitations/implications - The research is based on one case study on a small but active OSS project with an interest in users. Other kinds of OSS projects should be analysed. The analysis was focused on a discussion forum, but users can take part in OSS development by other means as well. Paths for future work should include the gathering of more varied empirical data. Practical implications - The findings indicate that users can provide feedback to the development through discussion forums in the distributed environment, but there is a need to support the users in doing so and the developers in analysing the data. The importance of different kinds of intermediaries ``representing the users{''} is highlighted. Originality/value - The paper provides thorough empirical insights and a refined conceptualisation of user participation addressing the currently weakly empirically explored OSS development context.",10.1108/09593840910962203

+1037,Article,rNMR: open source software for identifying and quantifying metabolites in NMR spectra,"Despite the extensive use of nuclear magnetic resonance (NMR) for metabolomics, no publicly available tools have been designed for identifying and quantifying metabolites across multiple spectra. We introduce here a new open source software tool, rNMR, which provides a simple graphics-based method for visualizing, identifying, and quantifying metabolites across multiple one- or two-dimensional NMR spectra. rNMR differs from existing software tools for NMR spectroscopy in that analyses are based on regions of interest (ROIs) rather than peak lists. ROIs contain all of the underlying NMR data within user-defined chemical shift ranges. ROIs can be inspected visually, and they support robust quantification of NMR signals. ROI-based analyses support simultaneous views of metabolite signals from up to hundreds of spectra, and ROI boundaries can be adjusted dynamically to ensure that signals corresponding to assigned atoms are analyzed consistently throughout the dataset. We describe how rNMR greatly reduces the time required for robust bioanalytical analysis of complex NMR data. An rNMR analysis yields a compact and transparent way of archiving the results from a metabolomics study so that it can be examined and evaluated by others. The rNMR website at http://rnmr.nmrfam.wisc.edu offers downloadable versions of rNMR for Windows, Macintosh, and Linux platforms along with extensive help documentation, instructional videos, and sample data.

I demonstrate how F/OSS developers contest and specify the meaning of liberal freedom -- especially free speech -- through the development of legal tools and discourses within the context of the F/OSS project. I highlight how developers concurrently tinker with technology and the law using similar skills, which transform and consolidate ethical precepts among developers. I contrast this legal pedagogy with more extraordinary legal battles over intellectual property, speech, and software. I concentrate on the arrests of two programmers, Jon Johansen and Dmitry Sklyarov, and on the protests they provoked, which unfolded between 1999 and 2003. These events are analytically significant because they dramatized and thus made visible tacit social processes. They publicized the challenge that F/OSS represents to the dominant regime of intellectual property (and clarified the democratic stakes involved) and also stabilized a rival liberal legal regime intimately connecting source code to speech.

This research -Management and use of distributed 3D data by open source Web-GIS software - is part of the Italian ``PRIN 2007{''}{*} research project, aimed to build urban and suburban 3D models, and to interact with them using open source software only. Particularly free and open source software, used for the experimentation here shown, are Blender and PostGIS; the first one has been used to build and structure three-dimensional data, the second one for data allocation. These software interact using scripts, written in Python language. Buildings have been modeled upon the GIANT3D model (Geographical Interoperable Advanced Numerical Topological 3-Dimensional Model) developed in the research ``PRIN 2004{''}, regarding ``Evolved structure of numerical cartography for Gis and Web-GIS{''}. Python scripts, activated by Blender, allow to allocate data into a spatial database implemented through PostgreSQL and PostGis, that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, are so transferred in PostGIS. These information can be retrieved by Blender using other Python scripts, so Blender fully interacts with 3D data allocated in PostGIS. These data can be also accessed by many other clients, both directly using a database client, as using other protocols (like HTTP on the internet). Next step is to build an open source viewer, or a plugin for internet browsers, that allows client to visualize, explore and inquiry 3D model, retrieving data from database.",NA

+1047,InCollection,A FREE SOFTWARE PLATFORM FOR EMBEDDED REAL-TIME ROBOTICS AND INDUSTRIAL AUTOMATION,"Embedded real-time platforms are a basic component of both robots and machines for the automation of industrial processes. Although industrial applications traditionally rely on PLC-based hardware and, in any case, proprietary software, i.e. operating systems and development tools, in recent years dramatic improvements in hardware computer power and free software quality made realistic the employment of architectures based on PC-compatible hardware and GNU/Linux software, more common in the research community. The advantages of a free infrastructure, that can become the terrain of fruitful cooperation between research institutions and companies, can be exploited mainly in fields, in which the added value is in the application, i.e. in mechanical and algorithmic solutions, and where the point of view is that of aware users of an infrastructure, rather than of R\\&D competitors. This is the case of the project presented in the following, representing a success story in which the discussion between a research group and a small enterprise led to the identification of the requirements and the joined development of a common software infrastructure. When the project started in 2004, both partners, i.e. the Autonomous robotic systems and control group of CNR-ISSIA and Green Project Srl, had to substitute the obsolete platforms of their marine robots and marking machines for casting products in steelworks with a stable software and hardware infrastructure able of transparently integrating technological improvements while remaining compatible with the past (backward compatibility). On the basis of considerations, discussed below, about system reliability, development and maintenance costs (including human resources), foreseen compatibility and general technical soundness, the choice was to verify the possibility of using standard GNU/Linux for embedded real-time applications. The result is the main technical contribution of this chapter, i.e. the practical demonstration of the possibility of using standard GNU/Linux for implementing embedded real-time control systems working up to a sampling frequency of at most 2 Khz. Furthermore, four years later, the developed system is still demonstrating its capabilities transparently integrating technological improvements and increasing more and more its performance thanks to the new real-time properties of the Linux kernel. A first operative release of the platform was completed in 2005 and integrated with the CNR-ISSIA Charlie unmanned surface vehicle (USV) for robotics research. A second application was the porting to the platform of the software of the control system of Hammer, a steelwork industrial machine used for marking continuous casting products, developed by Greenproject s.r.l. At the moment, the platform is supporting the development of the ALANIS (Aluminium Autonomous Navigator for Intelligent Sampling) USV1 for surface and underwater coastal monitoring. Moreover, the integration with generic field buses and image acquisition systems is being carried out. After an introduction reporting a summary of related research in the field and a discussion of the platform requirements, the key points of the followed methodology for making GNU/Linux real-time will be presented. Finally, two applications, a research one and an industrial one, pointing out the basic real-time structures that the platform is required to implement, will be described.",NA

Current literature has studied various aspects of OSS success such as project activity, user interest, and project effectiveness. However, this study focuses on user interest because, according to prior research, a higher user interest contributes to positive project outcomes (e.g. product quality, project performance, and project vitality). Based on the literature survey in this study, we found 43 conceptually distinct determinants of user interest in OSS projects. We classified them into 7 broad categories of including project status, project characteristics, community contribution, process, network structure, product characteristics, and resources. Implications for practice and research are also presented.",NA
+1053,InProceedings,A Longitudinal Analysis of the Dependency Concentration in Smaller Modules for Open-Source Software Products,"Our recent studies on single releases of multiple open-source software (OSS) products showed a higher concentration of dependencies in smaller modules. For one of the products, it was observed that an isolatable and observable refactoring initiative exacerbated this concentration inequality. In this paper, we empirically investigate the dependency concentration in smaller modules from a longitudinal perspective: (1) whether this concentration inequality always exists over product life time; (2) how it changes. We hypothesize that the concentration inequality should either remain at same levels or increase over time. This is because large-scale and long-lived software products usually go through some degree of continuous and intermittent refactoring. Our results show that dependencies concentrate in smaller classes in all releases, and this concentration inequality generally increases over successive releases. We suggest that software practitioners continuously pay a higher QA attention to smaller modules. We also recommend increasing such QA focus as a product matures and goes through refactoring activities.",NA

+1058,InProceedings,A Project Monitoring Cockpit Based On Integrating Data Sources in Open Source Software Development,"Many open source software (OSS) development projects use tools and models that come from heterogeneous sources. A project manager, who wants to analyze indicators for the state of the project based on these data sources, faces the challenge of how to link semi-structured information on common concepts across heterogeneous data sources, e.g., source code versions, mailing list entries, and bug reports. Unfortunately, manual analysis is costly, error-prone, and often yields results late for decision making. In this paper we propose linking OSS data sources using semantic web technologies as foundation for providing integrated indicators project status analysis. We introduce the design concept of a project monitoring cockpit, Pro-MonCo, and evaluate the feasibility and effectiveness with a pro-totype for calculating communication metrics in a real-world context, the Apache Tomcat project. Major result was that Pro-MonCo efficiently supports frequent project monitoring by calculating communication metrics based on semantically integrated data originating from heterogeneous OSS project data sources.",NA

To verify these relationships, we analyzed 6,773 Free Software projects from the SourceForge.net repository. The results indicated that attractiveness is indeed correlated to some source code metrics. This suggests that measurable attributes of the project source code somehow affect the decision to contribute and adopt a Free Software project. The findings described in this study show that it is relevant for project leaders to monitor source code quality, most specifically a few objective metrics, since these can have a positive influence in their chances of forming a community of contributors and users around the software, enabling further enhancement in its quality.",10.1109/SBES.2010.27

This paper aims to illustrate that if Free and/or Open Source Software is to be used as a building block to bridge the ""digital divide"" a more social and environmental perspective, which embraces the philosophy behind the software, needs to complement the technical perspective. The human environmental model is presented as a useful alternative which, if embraced, can inform more holistic information and communication technology (ICT) policies. Design/methodology/approach - Through a review of diffusion of innovations models an alternative diffusion framework is described and applied to an interpretive open source case study in South Africa. Findings - Contemporary diffusion and innovation models are narrowly focused on IT as a purely technological linear phenomenon. This perspective also underlies many ICT policies. A more socio-technical adoption model can assist in providing a more holistic approach to ICT policy development. Originality/value - The application of a new innovation model, the human environmental model, to ICT policy provides a holistic framework in which the complexity of the innovation process can be reflected in policy. Such an approach to ICT policy formulation will assist with broadening the perspective of policy makers from IT as a technical solution to IT as part of a socio-technical solution and recognise the duality of the innovation process.",10.1108/14779961011024837

In the geomorphologic survey, different landforms have been identified in the area, including structural, anthropogenic, fluvial, karst, and slope forms. In particular, the majority of the slope forms are complex (from topple to rotational slides and falls), but there are also minor forms like debris flows and mudslides. To manage geomorphological data, an Open Source GIS was used, which contained the following components: QuantumGIS, System for Automated Geoscientific Analyses (SAGA), GIS and Geographic Resources Analysis Support System (GRASS), GIS for Digital Elevation Model (DEM) generation. A key aim was to make the project-derived data available over the Web. This was achieved using MapServer which allows for the representation of the derived geospatial data with pMapper providing the graphical Web interface. Our study highlights the process dynamics of run-off erosion in Olvera derived through the use of advanced computer-based mapping tools.

This work copes with a relevant issue for this architecture, namely unresponsive components because of deadlocks and infinite loops. In particular, a monitor sends heartbeat messages to a component that should reply within a timeout. The timeout choice is tricky, since it should be dynamically adapted to the load conditions of the system. Therefore, our approach is based on an adaptive heartbeat mechanism, in which the timeout is estimated from past response times. We implement and compare three estimation algorithms for the choice of the timeout in the context of the Minix 3 OS. From the analysis we derive useful guidelines for choosing the best algorithm with respect to system requirements.",10.1109/DSNW.2010.5542619

+1075,InProceedings,Adoption of Open Source Software in Healthcare,"The Open Source (OS) platform is a new paradigm for software development in which several parties serve as volunteers in the design, coding, testing, debugging, distribution, and documentation of OS software projects. Open source software (OSS) is experiencing an exponential growth in several industries such as finance, sales and marketing, pharmaceuticals, and manufacturing. However, the adoption of OSS in healthcare has been slow despite the availability of several quality applications for the healthcare industry. In this paper, we outline the salient characteristics of OSS, including the development process for OSS, license types, and revenue models, and then discuss major factors that affect the uptake of OSS by organizations. With a detailed discussion of BI (Business Intelligence) and other open source applications available in healthcare, we conclude that the adoption of OSS in healthcare requires a comprehensive understanding of not only the needs of the healthcare sector, the types and complexities of OS applications, and how they interact with various organizational factors.",NA

This paper seeks to identify how organizations adopt OSS, classify the literature according to these ways of adopting OSS, and with a focus on software development evaluate the research on adoption of OSS in organizations. Based on the systematic literature review method, the authors reviewed publications from 24 journals and seven conference and workshop proceedings, published between 1998 and 2008. From a population of 24,289 papers, the authors identified 112 papers that provide empirical evidence on how organizations actually adopt OSS. The authors show that adopting OSS involves more than simply using OSS products. The authors moreover provide a classification framework consisting of six distinctly different ways in which organizations adopt OSS. The authors find that existing research on OSS adoption does not sufficiently describe the context of the organizations studied, and it fails to benefit fully from related research fields.",NA

+1078,InProceedings,An Empirical Study on the Structural Complexity Introduced by Core and Peripheral Developers in Free Software Projects,"Background: Several factors may impact the process of software maintenance and evolution of free software projects, including structural complexity and lack of control over its contributors. Structural complexity, an architectural concern, makes software projects more difficult to understand, and consequently more difficult to maintain and evolve. The contributors in a free software project exhibit different levels of participation in the project, and can be categorized as core and peripheral developers. Research aim: This research aims at characterising the changes made to the source code of 7 web server projects written in C with respect to the amount of structural complexity added or removed and the developer level of participation. Method: We performed a observational study with historical data collected from the version control repositories of those projects, recording structural complexity information for each change as well as identifying each change as performed by a core or a peripheral developer. Results and conclusions: We have found that core developers introduce less structural complexity than peripheral developers in general, and that in the case of complexity-reducing activities, core developers remove more structural complexity than peripheral developers. These results demonstrate the importance of having a stable and healthy core team to the sustainability of free software projects.",10.1109/SBES.2010.26

A crucial issue for facilitating interaction with these 3D city models is the ability to integrate 3D BIM into the geospatial context. This requires the use of specialized software and specific expertise. In order to simplify this process, we here propose an information system that facilitates the use of BIM for geo-analysis purposes. BIM4GeoA is a concept for combining existing open source software and open specification for efficient data management and analysis of Building Information within its boarder context. The core components are the spatial database PostgreSQL/PostGIS, the building information server, the industrial foundation class (IFC), the Google Earth 3D viewer, and the existing 3D OGC standard (KML, CityGML). This paper presents the procedure used to enable the development of this new expert system as applied to the context of 3D Web GIS. A thorough analysis of the strength and weakness of these different components has been undertaken to employ it is strength and override its weakness.

A virtual social network is therefore formed through a mailing list, in which, each subscriber could be a node of the network, and the communications (email messages) could be the links of the network. Due to the virtual property of this network, physical (geographical) distance between network nodes is usually considered irrelevant. Instead, what is more important is the conceptual distance that captures the key properties of this virtual network. This paper studies the open-source software developer network. Two types representation of the conceptual distance, message reply distance and common keyword distance, are defined. Appling these two types of conceptual distances, the mailing list of Linux kernel project is mined and virtual networks are constructed and analyzed. The evolution of Linux Kernel Mailing List social network is studied, where Mantel test is used to study the similarities and correlations between social networks. The study shows that in open-source software projects, (1) conceptual distances could be the key components in constructing the workspace of the developer network, and (2) Mantel test could be a powerful tool in studying the network.",NA

In contrast, research on the corresponding ``receiving{''} side of the innovation process is scarce. We address this gap, studying how existing OSS code is reused and serves as an input to further OSS development. Our findings are based on a survey with 686 responses from OSS developers. As the most interesting results, our multivariate analyses of developers' code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early-as the ``credible promise{''} in OSS-leads to increased reuse. Finally, we identify developers' interest in tackling difficult technical challenges as detrimental to efficient reuse-based innovation. Beyond OSS, we discuss the relevance of our findings for companies developing software and for the receiving side of open innovation processes, in general.",NA

This paper examines this corporatizing effect by studying the relationship between peer-oriented social structures and goal-oriented technical structures in the Plone community. Social structures are said to exhibit assortative mixing, a like attract like characteristic whereas technical structures exhibits an opposite effect of disassortative mixing. Our first finding suggests that the patterns of collaborative contributions and interdependences among software modules exhibit the characteristic of disassortative mixing. Specifically, Plone developers were more likely to contribute to modules that already have a high concentration of contributions, which in turn lead to an increase in module reuse over time. This finding contributes to the debate of whether social systems are strictly assortative, and technological systems strictly disassortative (Newman, 2002). Our second contribution concerns the impact of corporatizing OSS projects, suggesting that corporatizing OS development had the effect of weakening the social organizing among developers, and shifted the patterns of contributions to adhere with the technical requirements.",NA

+1109,Article,Developer Heterogeneity and Formation of Communication Networks in Open Source Software Projects,"Over the past few years, open source software (OSS) development has gained a huge popularity and has attracted a large variety of developers. According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at Source Forge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects.",10.2753/MIS0742-1222270307

Project communities and customer pipelines are not the same thing, although some participants belong to both groups. This creates confusion in the business and tension with the community. F/LOSS communities have been on the rise for the past two decades. Companies began to form around F/LOSS projects in the early 1990s, with some creating their own F/LOSS projects and some wrapping themselves around existing projects. This has created tension between company managers who are trying to earn profits from software that is ""available for free,"" and from developers in communities that do not necessarily want to create software for someone else's corporate gain. This happens regardless of whether the company created the F/LOSS-licensed project itself, or participates in external communities around other projects, or both.

+1117,Article,Dynamics of Bio-Oss® Collagen incorporation in fresh extraction wounds: an experimental study in the dog,"Aim The objective of this experiment was to analyze processes involved in the incorporation of Bio-Oss (R) Collagen in host tissue during healing following tooth extraction and grafting. Methods Five beagle dogs were used. Four premolars in the mandible (P-3(3), P-4(4)) were hemi-sected, the distal roots were removed and the fresh extraction socket filled with Bio-Oss (R) Collagen. The mucosa was mobilized and the extraction site was closed with interrupted sutures. The tooth extraction and grafting procedures were scheduled in such a way that biopsies representing 1 and 3 days, as well as 1, 2 and 4 weeks of healing could be obtained. The dogs were euthanized and perfused with a fixative. Each experimental site, including the distal socket area, was dissected. The sites were decalcified in EDTA, and serial sections representing the central part of the socket were prepared in the mesio-distal plane and parallel with the long axis of the extraction socket. Sections were stained in hematoxylin and eosin and were used for the overall characteristics of the tissues in the extraction socket. In specimens representing 1, 2 and 4 weeks of healing the various tissue elements were assessed using a morphometric point counting procedure. Tissue elements such as cells, fibers, vessels, leukocytes and mineralized bone were determined. In deparaffinized sections structures and cells positive for tartrate-resistant acid phosphatase activity (TRAP), alkaline phosphatase and osteopontin were identified. Results The biomaterial was first trapped in the fibrin network of the coagulum. Neutrophilic leukocytes {[}polymorphonuclear (PMN) cells] migrated to the surface of the foreign particles. In a second phase the PMN cells were replaced by multinuclear TRAP-positive cells (osteoclasts). The osteoclasts apparently removed material from the surface of the xenogeneic graft. When after 1-2 weeks the osteoclasts disappeared from the Bio-Oss (R) granules they were followed by osteoblasts that laid down bone mineral in the collagen bundles of the provisional matrix. In this third phase the Bio-Oss (R) particles became osseointegrated. Conclusions It was demonstrated that the incorporation of Bio-Oss (R) in the tissue that formed in an extraction wound involved a series of different processes.

For laboratory lectures, we need a tool that is complete and easy to use. In this work we present a Java library which is oriented to teaching. This means that we have designed and built the library thinking in readability and understanding instead of efficiency. In this paper we present the open source project JavaVis, oriented to Computer Vision teaching. It consists of a framework with several features that make it useful for that purpose. It was designed to be easy to use: the user does not have to deal with internal structures and graphical interface, and adding a new algorithm is a simple task. We have developed three different modules, based on three different needs we have noticed in our subjects. The first one is a basic library for image processing. Besides the previously commented features, it supports geometrical data (edges, segments, points, etc.). The second module is based on the same working schema as the first one, but applied to 3D data. These two modules are enough for testing many well-known algorithms. They also suit the programming needs of students and teachers, as they can easily develop their own algorithms for the JavaVis framework. All JavaVis functions can be launched both from command line, as well as with the JavaVis Graphical User Interface. Finally we have extended JavaVis with a third module consisting of a visual desktop where different Computer Vision functions can be easily placed and connected. Its purpose is to visualize intermediate results in processes involving several functions, helping their better understanding. Once the library is presented, we focus on the experience using this library in several computer science courses. Our main goal using this library is that the students understand what they are doing. We have taken questionnaires during two years in order to know the improvement the students have gotten using the library. Results are shown and conclusions are drawn.",NA

And Platelet poor plasma (PPP) is the by-product in procedure of producing PRP. Six rabbits were used as experimental animal. Both maxillary sinus were grafted with Bio-Oss (R) and PRP, and Bio-Oss (R) and PPP. Rabbits were sacrificed at 4, 8 and 12 weeks. The grafting sites were evaluated by histomorphometric analysis. As a result, using PRP showed excellent bone formation in the early stage, but no further significant effect after that. In late stage, the ability of bone formation of using PRP was even worse than using PPP. The further studies need to be considered in this case.",10.5125/jkaoms.2010.36.1.39

This paper qualitatively documents the decision of the largest UK e-learning provider, the Open University, to adopt the Mood le e-learning system, and how it has been successfully deployed in its site after a multi-million investment. A further quantitative study also provides evidence of how a commercial stakeholder has been engaged with, and produced outputs for, the Mood le community. Lessons learned from this experience by the stakeholders include the crucial factors of contributing to the OSS community, and adapting to an evolving technology. It also becomes evident how commercial partners helped this OSS system to achieve the transition from an ``average{''} OSS system to a successful multi-site, collaborative and community-based OSS project.",NA

However, turnover of members and the ensuing instability have become very common. To better understand the turnover of members in OSS projects, we base our study on Herzberg's two-factor theory to investigate whether hygiene factors will lead to members' dissatisfaction. At the same time, we draw on Mobley's model of withdrawal decision process to hypothesize the relationship between dissatisfaction and perceived turnover. We develop a research model and present hypotheses that should be tested in the future. To empirically assess this model, we intend to survey OSS project members through the largest development platform Sourceforge. This study will provide a new insight into how the turnover of members emerges in OSS projects. The findings of this progressive research will have implications for both practice and theory.",NA

The results of an experiment involving a group of OSS users inspecting an open source project called dotproject demonstrate that this method outperforms traditional heuristics based inspection The paper also considers the applicability of the usability method and tool developed to usability improvement in the context of traditional proprietary development Copyright (C) 2010 John Wiley \\& Sons, Ltd",10.1002/smr.455

Using cross-sectional and longitudinal data on a sample of 108 open source projects, this research investigated how the complexity of open source project releases varied throughout the life of the project. Functional data analysis was applied to the release histories of the projects and recurring evolutionary patterns were derived. There were projects that saw little evolution, according to their measures of size and structural complexity. However, projects that displayed some evolution often differed on the pattern of evolution depending on whether size or structural complexity was examined.

Traditionally, research in FOSS has focused on identifying individual personal motives for participating in the development of a FOSS project, analyzing specific FOSS solutions, or the FOSS movement itself. Nevertheless, the advantages of the FOSS for users and the effect of the demographic dimensions on user acceptance for FOSS have been two research topics with little attention.

We propose a socio-technical pattern that can be used to locate emerging coordination problems in Open Source projects. With the help of our tool and method called TESNA, we demonstrate a method to monitor the socio-technical core-periphery movement in Open Source projects. We then study the impact of different core-periphery movements on Open Source projects. We conclude that a steady core-periphery shift towards the core is beneficial to the project, whereas shifts away from the core are clearly not good. Furthermore, oscillatory shifts towards and away from the core can be considered as an indication of the instability of the project. Such an analysis can provide developers with a good insight into the health of an Open Source project. Researchers can gain from the pattern theory, and from the method we use to study the core-periphery movements.

Recently, the focus has shifted toward an examination of a newer construct -temporal dispersion (TD). The study of TD so far has been constrained mostly to conceptual work. This study furthers the understanding of TD through an empirical investigation of its relationship with open source software (OSS) team performance. In this paper, hypotheses are developed based on coordination theory, and analyses are performed using data collected from multiple archival sources comprising 100 OSS development teams. Results indicate that TD positively affects development speed and quality and that software complexity moderates the relation between TD and software quality.

+1140,Article,Free GIS for herpetologists: free data sources on Internet and comparison analysis of proprietary and free/open source software,"Geographical Information Systems (GIS) have been used widely in zoology and ecology, particularly in herpetology. The use of spatially explicit analysis has increased during the last decade, with the consequent expansion of GIS application in ecology. During the last years, geo-information technology has been developed within the Free/Open Source Software (FOSS) community, resulting in new open source formats and several GIS packages. However, proprietary packages seem still to be the first choice for herpetologists, thus involving non negligible costs for GIS technology adoption. Additional costs arise from environmental data, which are usually expensive, worsening in the case of large study areas. An alternative solution is to use freely available data, despite a possible decrease of resolution. In this review, we aim to show the feasibility of spatial analysis within FOSS GIS packages, rank these packages using the number of available tools and list several data sources freely available on the Internet. We listed several websites providing the most important free data for spatial analysis, i.e. altitude and derived data; past, current and future climatic series data; and satellite derived data. We provide also a list of the most commonly used functions in GIS analysis and their availability in the six software compared in this study (ArcGIS; gvSIG; ILWIS; Quantum GIS; GRASS; and DIVA-GIS). The software gvSIG is the one with more functions (106) followed by Quantum GIS with 94 and GRASS with 84.",NA

+1142,InProceedings,Free and Open-Source Software is not an Emerging Property but Rather the Result of Studied Design,"Free and open source software (FOSS) is considered by many, along with Wikipedia, the proof of an ongoing paradigm shift from hierarchically-managed and market-driven production of knowledge to heterarchical, collaborative and commons-based production styles. In such perspective, it has become common place to refer to FOSS as a manifestation of collective intelligence where deliverables and artefacts emerge by virtue of mere cooperation, with no need for supervising leadership. We show that this assumption is based on limited understanding of the software development process, and may lead to wrong conclusions as to the potential of peer production. The development of a less than trivial piece of software, irrespective of whether it be FOSS or proprietary, is a complex cooperative effort requiring the participation of many (often thousands of) individuals. A subset of the participants always play the role of leading system and subsystem designers, determining architecture and functionality; the rest of the people work ``underneath{''} them in a logical, functional sense. While new and powerful forces, including FOSS, are clearly at work in the post-industrial, networked economy, the currently ingenuous stage of research in the field of collective intelligence and networked cooperation must give way to a deeper level of consciousness, which requires an understanding of the software development process.",NA

With FOSS emerged the freedom to run the programs for any purpose, freedom to study and modify the software, freedom to copy the software and share with neighbors and freedom to improve the program and release your improvements to the public, so that the whole community benefits. This paper makes a case for these freedoms. The paper first compares PS and FOSS use in Ghana and proposes a way for government to adopt FOSS.

In more recent years, FOSS is becoming an increasingly important element in strategies for development and implementation of information and communication technologies also in developing countries. Mainstream research on FOSS has catered to the underlying principles or freedom, open organizational forms, and on its economical aspects. The purpose of this paper is to shed new light on the actual consequences of FOSS, often left in the background. Design/methodology/approach - The paper examines where FOSS principles' assumptions are likely to be more evident: in contexts of developing countries, which are geographically and organizationally far from the original environment of FOSS. A mixed methodology characterizes this work: quantitative and qualitative methods bring readers' attention to unusual empirical settings and downplayed organizational processes of information technology (IT) implementation and adoption. Findings - The consequences of FOSS on IT implementation and actual use are ambivalent. It is argued that FOSS adoption does not happen spontaneously, neither by decree, and that the relevance of open technologies as public goods remains in the different role of local actual technical and organizational capabilities, and environment conditions. Originality/value - Such a focus complements existing studies on the economical relevance of FOSS, which are not the focus of this paper.",10.1108/14779961011024800

OSS projects are typically organized as edge organizations lacking an explicit management regime to control and coordinate decentralized project work. However, a growing number of OSS projects are developing, delivering, and supporting large-scale software systems, displacing proprietary software alternatives. Recent empirical studies of OSS projects reveal that OSS developers often self-organize into organizational forms we characterize as evolving socio-technical interaction networks (STINs). STINs emerge in ways that effectively control semi-autonomous OSS developers and coordinate project activities, producing reliable and adaptive software systems. In this paper, we examine how practices and processes enable and govern OSS projects when coalesced and configured as contingent, socio-technical interaction networks. We draw on data sources and results from two ongoing case studies of governance activities and elements in a large OSS project.",NA

Besides some much-reported benefits of this approach, using OSS products also presents new challenges. One such challenge is identifying relevant, high-quality OSS products among the hundreds of thousands that are available. One approach for doing that is to identify architectural patterns, since these patterns have a direct effect on a product's quality attributes, such as performance and reliability. However, there are no well-defined methods or tools available to identify architectural patterns.Research aim: Our goal is to identify approaches taken by novice software engineers that have no or little experience in identifying architectural patterns.

+1171,InProceedings,Modelling Failures Occurrences of Open Source Software with Reliability Growth,"Open Source Software (OSS) products are widely used although a general consensus on their quality is far to be reached. Providing results on OSS reliability - as quality indicator contributes to shed some light on this issue and allows organizations to make informed decisions in adopting OSS products or in releasing their own OSS. In this paper, we use a classical technique of Software Reliability Growth to model failures occurrences across versions. We have collected data from the bug tracking systems of three OSS products, Mozilla Firefox, OpenSuse and OpenOffice.org. Our analysis aims at determining and discussing patterns of failure occurrences in the three OSS products to be used to predict reliability behaviour of future releases. Our findings indicate that in the three cases, failures occurrences follow a predetermined pattern, which shows: a) an initial stage in which the community learns the new version b) after this first period a rapid increase of the failure detection rate until c) very few failures are left and the discovery of a new failure discovery is rare. This is the stage in which the version can be considered reliable.",NA

+1173,Article,Not Just Software: Free Software and the (Techno) Political Action,"The practice of developing and creating Free Software has been the centre of attention for studies related to economics, knowledge production, laws and the intellectual property framework. However, the practice that constitutes the initiative of Free Software also means a call to rethink current forms of political action and the in-depth meaning of what is understood as ``political{''}. This constitutes the field which has been called techno-activism. Along these lines, the authors propose a particular reading of the political challenge that is Free Software from the standpoint of Hardt and Negri's (2000) theoretical work. The authors put forward various contributions-regarding the organization, the agents and the form of political action-that they consider to pose a crisis for traditional proposals and urge society to renew its way of relating to information, the raw material upon which the current exercise of government and practices of techno-activist resistance rest.",10.4018/jte.2010040104

New distributed development paradigm typified by such open source project will evolve at a rapid pace in the future. Especially, OSS (Open Source Software) systems which serve as key components of critical infrastructures in the society are still ever-expanding now. We focus on the porting-phase of OSS developed under open source project. In this paper, we discuss the software reliability assessment method based on flexible hazard rate model considering the latent fault in embedded OSS and unique sodtware components. Also, we analyze actual software fault data to show numerical examples of OSS in the porting-phase. Moreover, we estimate the optimal release time minimizing the total expected software cost.",NA

+1177,InCollection,ORGANIZATIONAL AND MOTIVATIONAL FACTORS FOR IMPLEMENTING ENTERPRISE SOLUTIONS BASED ON OPEN SOURCE SOFTWARE,"Organizations implement Enterprise solutions, mainly Enterprise Resource Planning (ERP) systems, with the aim of attaining operational efficiency and the incorporation into new markets through the real time information flow control of the entire organization. However, ERP systems are complex tools, particularly for small and medium size enterprises (SMEs). For this reason, new ERP configurations have arisen, such as Open Source Software-ERP (OSS-ERP). In the website Sourceforge.net, we can identify 2058 projects about OSS-ERP, although all of them have not had an impact on the ERP market. This data is indicative of the increasing relevance of this enterprise solution for organizations. At this moment, the OSS-ERP vendors with a greater diffusion are Compiere, Openbravo, Abanq (previously FacturaLux), ERP5, Tiny ERP, Fisterra, OFBiz, SQL-Ledger and WebERP. OSS-ERP has three relevant advantages for organizations: (1) increased adaptability, (2) decreased reliance on a single supplier, (3) reduced costs. OSS-ERP generally include the necessary functions to integrally manage all the activities of a company. Due to their high flexibility, these tools can be adapted to the client's specific needs. Furthermore, as OSS-ERP are based on open software technologies, organizations do not have to pay licenses or exclusive contracts. With the collaboration of partners, OSS-ERP vendors receive benefits for the support services. Research in OSS has identified individual personal motives for using OSS software, analyzing specific OSS solutions, or the OSS movement itself. The literature in Enterprise solutions has also analyzed the main organizational factors for successfully implementing an ERP system. However, OSS-ERP is a research topic barely analyzed by the literature. This paper's aim is to specifically focus on the organizational and motivational factors for implementing OSS-ERP. The authors developed a research work for testing the impact of organizational and motivational factors on the implementation of OSS-ERP by means of a survey of organizations with OSS-ERP and OSS-ERP users.",NA

+1180,Article,Open Innovation in Secondary Software Firms: An Exploration of Managers' Perceptions of Open Source Software,"Open source software (OSS) is probably the best known exemplar of open innovation, with many practitioner-oriented publications having debated the merits and drawbacks of OSS in recent years. Nevertheless, much of the academic research on OSS has focused on individual rather than organizational issues. Hence while there is some understanding of why individual developers and users opt for particular OSS applications, relatively little is known about the adoption of OSS as a software acquisition policy. This paper presents a study of 13 managers in the secondary software sector in Europe, and examines how their perceptions of the benefits and drawbacks of OSS affected their decision to adopt an open source policy for software in their companies. The study reveals how their perceptions of the business and technical benefits and drawbacks of OSS influenced the technological, organizational, environmental and individual factors considered within the adoption process. The findings reveal that many of these factors are similar to those reported by previous work on the adoption of innovation, leading us to conclude that organizational processes for the adoption of open innovation are reliant on the practices for closed innovation despite frequently cited loss of organizational control associated with open innovation.",NA

To overcome the problem of piracy local Information Technology (IT) companies are willing to migrate towards Open Source Software (OSS). Due to this reason need for framework/model for OSS adoption has become more pronounced. Research on the adoption of IT innovations has commonly drawn on innovation adoption theory. However with time some weaknesses have been identified in the theory and it has been realized that the factors affecting the adoption of OSS varies country to country. The objective of this research is to provide a framework for OSS adoption for local environment and then compare it with the existing framework developed for OSS adoption in other advanced countries. This paper proposes a framework to understand relevant strategic issues and it also highlights problems, restrictions and other factors that are preventing organizations from adopting OSS.

This article considers the dynamics of value creation fuelling the proliferation of OSS and examines the business model factors that enable value capture. After interviewing leaders from over 20 OSS firms and organisations through early 2006, we found that three factors were consistently important in defining a vendor's adoption of a given business model: software licence choice, which takes into account intellectual property ownership; management of developer communities; and the unique features of the markets and product categories in which the vendor participates. Considering these factors, we characterise seven business models. One striking finding is that it is rare to find business-model purity. The majority of firms in our sample are pursuing either blended business models or multiple models simultaneously.",10.1504/IJTM.2010.035984

What kind of partnerships can be explored in order to further use of OSS in the state? Design/methodology/approach - The paper highlights findings from an exploratory website study to identify key trends, practices, and applications of use of OSS in the TRLS. Findings - OSS applications in the TRLS are presented in terms of their current use as well as their future directions of development and opportunities. Study of collaborations in OSS use and website development by public libraries in the TRLS reveals that the OSS infoscape is more complex than previously understood. Originality/value - Minimal research has been done involving the TRLS that has been in existence for over 60 years and comprises 12 multi-county regions serving 211 small-and medium-sized public libraries. Use of OSS has tremendous potentialities to overcome the harsh conditions of information poverty, lack of information resources and technology, and unique cultural, social, economic, and environmental challenges experienced in Tennessee that have prevented significant growth of information and communications technologies in the state.",10.1108/00242531011087015
+1186,Article,Open source software deployment in the public sector: a review of Botswana and South Africa,"Purpose - The purpose of this paper is to review use of open source software in the public sector in Botswana and South Africa. South Africa is Botswana's neighbor and both countries are leading economies in Africa. Design/methodology/approach - The paper draws on a survey that was carried out in information communication technology (ICT)-intensive government ministries in Botswana in May 2008. The study sought to establish availability of policy framework, level of usage of open source software, government support, motivations for implementing open source software in government, availability of skills, attitude of it managers in government toward open source software and challenges of open source software deployment in the public sector. The population of the study consisted of information technology (IT) managers who were purposively selected from ICT-intensive government ministries and interviewed. The study was extended to cover South Africa through review of literature on the same issues as those studied in Botswana. Findings - Compared with other countries in developed and developing countries including South Africa, there is limited use of open source software in the public sector in Botswana. However, IT managers in government of Botswana demonstrate a positive attitude toward open source software, and seem to have adequate understanding of its potential benefits. Comparatively, South African government provides support for harnessing open source software; awareness among top government officials is high and attitude toward open source software seems positive; skills are generally available and hardly any challenges of using open source software were identified. Research limitations/implications - This study was limited to purposively selected government ministries which are ICT-intensive in Botswana, while for South Africa, the study was based on secondary sources of data and focused on deployment of open source software in government agencies. Practical implications - Despite the increasing deployment of open source software in government across the world, the Botswanan government is yet unlikely to put in place an enabling open source software policy to harness the potential of the Software. Originality/value - Open source software deployment in government across the world is gaining momentum purportedly to enhance universal access, reduce costs associated with commercial software bridge the digital divide, grow indigenous IT skills, etc. Botswana and South Africa are the economic frontline states in Africa, and their leadership role in this matter among counterparts on the African continent is pertinent.",10.1108/07378831011026698

In this paper we report from a case study conducted in a company context aiming to investigate the feasibility of using Open Source approaches for curation of corporate digital assets kept in proprietary legacy file formats to open file formats. We consider different aspects of openness in a corporate strategy for maintaining digital assets. An important aspect concerns activity and company influence in an Open Source tool-chain, another concerns support for data curation of digital assets actually offered by the tool chain. We find that organisational concern over legacy file formats continues to be an issue, and that strong commercial influence on Open Source projects is no guarantee for success.",10.1145/1930488.1930501
+1189,Article,Open source software: A community of altruists,"To learn about what drives people to devote their time and expertise to creating and supporting free/open source software, a survey with Likert-scaled items measuring different types of motivations was sent to contributors of several open source projects. Open-ended comments were used to illustrate the Likert-scaled items and open-ended questions allowed respondents to express their reasons for participating in these open source communities. Results indicate that the open source contributors (n = 110, 38 paid to work on OSS projects and 72 volunteers) are motivated primarily by a sense of altruism as well as the desire to create and learn. Payment did not significantly impact the reasons for contributing to OSS projects. The comments and open-ended questions validated the findings and indicated that building a ``Utopian{''} community - the desire to help for the greater good worldwide - is one of the most important motivators. Also, respondents revealed that they join and persist as members of open source communities because they enjoy the freedom to create and share free software, tools and knowledge with others inside and outside the community.

+1193,Article,OptFlux: an open-source software platform for in silico metabolic engineering,"Background: Over the last few years a number of methods have been proposed for the phenotype simulation of microorganisms under different environmental and genetic conditions. These have been used as the basis to support the discovery of successful genetic modifications of the microbial metabolism to address industrial goals. However, the use of these methods has been restricted to bioinformaticians or other expert researchers. The main aim of this work is, therefore, to provide a user-friendly computational tool for Metabolic Engineering applications. Results: OptFlux is an open-source and modular software aimed at being the reference computational application in the field. It is the first tool to incorporate strain optimization tasks, i.e., the identification of Metabolic Engineering targets, using Evolutionary Algorithms/Simulated Annealing metaheuristics or the previously proposed OptKnock algorithm. It also allows the use of stoichiometric metabolic models for (i) phenotype simulation of both wild-type and mutant organisms, using the methods of Flux Balance Analysis, Minimization of Metabolic Adjustment or Regulatory on/off Minimization of Metabolic flux changes, (ii) Metabolic Flux Analysis, computing the admissible flux space given a set of measured fluxes, and (iii) pathway analysis through the calculation of Elementary Flux Modes. OptFlux also contemplates several methods for model simplification and other pre-processing operations aimed at reducing the search space for optimization algorithms. The software supports importing/exporting to several flat file formats and it is compatible with the SBML standard. OptFlux has a visualization module that allows the analysis of the model structure that is compatible with the layout information of Cell Designer, allowing the superimposition of simulation results with the model graph. Conclusions: The OptFlux software is freely available, together with documentation and other resources, thus bridging the gap from research in strain optimization algorithms and the final users. It is a valuable platform for researchers in the field that have available a number of useful tools. Its open-source nature invites contributions by all those interested in making their methods available for the community. Given its plug-in based architecture it can be extended with new functionalities. Currently, several plug-ins are being developed, including network topology analysis tools and the integration with Boolean network based regulatory models.",10.1186/1752-0509-4-45

Our results indicate that FOSS project members possess rather sophisticated notions of software usability, which collectively mirror definitions commonly found in HCI textbooks. Our study also uncovered a wide range of practices that ultimately work to improve software usability. Importantly, these activities are typically based on close, direct interpersonal relationships between developers and their core users, a group of users who closely follow the project and provide high quality, respected feedback. These relationships, along with positive feedback from other users, generate social rewards that serve as the primary motivations for attending to usability issues on a day-to-day basis.

+1204,Article,Performance enhancement and validation of the open-source software for modeling of ship infrared signatures (OSMOSIS),"Designing stealth technologies for modern warships requires methods for signatures reduction (radar, infrared, etc). First, we have to model these signatures. In Lapierre et al. (2006), Lapierre et al. (2007) {[}3,4], we proposed an infrared (IR) ship signature simulation software (OSMOSIS) that can manage parametric emissivity. OSMOSIS comprises a smart computation time and memory management. Evaluating the effectiveness of an IR signature reduction method implies simulating the evolution of the IR signature with time. This requires a huge computation time. In this paper, we propose a novel hierarchical meshing strategy leading to an important reduction of the computation time. The time complexity of the algorithm is shown to be O(root N), where N is the requested number of facets of the mesh of the ship's surface. Then, we validate OSMOSIS on temperature measurements performed on an ``L-shape{''} object. (C) 2009 Elsevier B.V. All rights reserved.",10.1016/j.cam.2009.08.091

Methods We used open source software to build a data management system and an internet application with a Flex client on a Java application server with a MySQL database backend. The application is hosted on Amazon Elastic Compute Cloud. This solution named Phynx supports data management, Web-based display of electronic patient information, and interactive review of patient-level information in the individual clinical context. This system was applied to a dataset from the UK General Practice Research Database (GPRD). Results Our solution can be setup and customized with limited programming resources, and there is almost no extra cost for software. Access times are short, the displayed information is structured in chronological order and visually attractive, and selected information such as drug exposure can be blinded. External experts can review patient profiles and save evaluations and comments via a common Web browser. Conclusions Phynx provides a flexible and economical solution for patient-level review of electronic medical information from databases considering the individual clinical context. It can therefore make an important contribution to an efficient validation of outcome assessment in drug safety database studies. Copyright (c) 2009 John Wiley \\& Sons, Ltd.",10.1002/pds.1860

These organizations are voluntary in nature and rely on contributions from members to achieve their objectives. Examples include the Linux operating system and other FOSS projects, political movements, churches and religious groups, Habitat for Humanity, and similar charitable organizations. In this paper, we consider a world containing agents with heterogeneous abilities who may voluntarily choose to make effort contributions to one or more different public projects. Agents are motivated by a desire to be seen as significant contributors to important and valuable projects, the warm glow from the act of contributing, and a desire to directly enjoy the benefits of projects when complete. We find that contributions from others can be either strategic complements or substitutes. We show that Nash equilibria exist and study how agents' abilities and project quality affect the equilibrium levels of contributions.",10.1111/j.1467-9779.2009.01469.x

Materials and Methods: A structured questionnaire was randomly distributed to 500 dental hygienists and 500 dentists and a similar questionnaire was distributed to 1000 randomly selected individuals, divided equally into the following age groups: 15 to 20, 21 to 40, 41 to 60 and > 60 years. A clinical examination evaluating the ability to remove approximal dental plaque was also carried out in a total of 60 regular users of approximal cleaning aids. Plaque was scored before and after cleaning with a toothpick, dental floss or an interdental brush. Results: The response rate was 82\\%, 79\\% and 68\\% for the three groups. The results reveal that dental hygienists give more detailed information about a majority of the aspects that are related to the use of approximal cleaning aids compared with dentists (P < 0.01 or P < 0.001). The majority of the dental staff give recommendations to children and adolescents firstly to prevent dental caries and to older individuals to improve periodontal health. The use of different approximal cleaning aids on a daily basis varied with respect to age group (2\\% to 42\\%); dental floss dominated in the younger age groups and interdental brushes in the two oldest groups. In the clinical study, the largest plaque reduction was produced by the interdental brush (83\\%), followed by toothpicks (74\\%) and dental floss (73\\%). Conclusions: The present study indicated the importance of individual recommendations related to the use of approximal cleaning aids.",NA

These platforms are usually centered in a specific brand/product and their members are linked by a shared admiration to that brand. This paper analyzes one of the most powerful online collaborative platforms, the free software (FS) case, which involves a lot of virtual communities developed around products such as Linux or Android, the new Google's mobile operating system. Our purpose is to determine some of the main antecedents and consequences of the consumer involvement in this type of communities. Results have shown that satisfaction with a virtual community may increase the level of consumer participation in that community. At the same time, a greater identification with the virtual community may increase indirectly the consumer participation thanks to the enhancement of his/her satisfaction with the community. We have also found positive and significant effects of consumer identification and participation on the level of community promotion. Finally, positive and significant effects of consumer participation and satisfaction with the community on loyalty to the FS were also found. These findings allow us to conclude some interesting managerial implications. (C) 2010 Elsevier Ltd. All rights reserved.",10.1016/j.ijinfomgt.2010.01.004

+1216,Article,"SPLASSH: Open source software for camera-based high-speed, multispectral in-vivo optical image acquisition","Camera-based in-vivo optical imaging can provide detailed images of living tissue that reveal structure, function, and disease. Highspeed, high resolution imaging can reveal dynamic events such as changes in blood flow and responses to stimulation. Despite these benefits, commercially available scientific cameras rarely include software that is suitable for in-vivo imaging applications, making this highly versatile form of optical imaging challenging and time-consuming to implement. To address this issue, we have developed a novel, open-source software package to control high-speed, multispectral optical imaging systems. The software integrates a number of modular functions through a custom graphical user interface (GUI) and provides extensive control over a wide range of inexpensive IEEE 1394 Firewire cameras. Multispectral illumination can be incorporated through the use of off-the-shelf light emitting diodes which the software synchronizes to image acquisition via a programmed microcontroller, allowing arbitrary high-speed illumination sequences. The complete software suite is available for free download. Here we describe the software's framework and provide details to guide users with development of this and similar software.

The key trend in the evolution of FLOSS quality assessment models is the movement from manual and descriptive to more automated and analytical models, and from the involvement of a few metrics to hundreds of metrics. Concerning the security measurements, they are much more sophisticated in QualOSS than in OpenBRR. Where OpenBRR have only three security metrics, QualOSS has nine security indicator with altogether 30-40 security metrics.

Our analysis draws on a large sample of projects registered at Sourceforge.net, the world's largest incubator of open source software activity. We test the hypothesis that skill variety of participants is associated with project performance. We also explore whether the level of modularization of project activities is correlated with performance. Our econometric estimations show that skill heterogeneity is associated with project survival and performance. However, the relationship between skill diversity and performance is non-monotonic. Design modularity is also positively associated with the performance of the project. Finally, the interaction between skill heterogeneity and modularity is negatively associated with performance.

While the benefits resulting from network externality have been examined in the related literature, the effect of free offer on the diffusion of new software has not been formally analyzed. We show in this study that even if other benefits do not exist, a software firm can still benefit from giving away fully functioning software. This is due to the accelerated diffusion process and subsequently the increased net present value of future sales. By adapting the Bass diffusion model to capture the impact of free software offer, we provide a methodology to determine the optimal number of free adopters. We show that the optimal free offer solution depends on the discount rate, the length of the demand window, and the ratio of low-valuation to high-valuation free adopters. Our methodology is shown to be applicable for both fixed and dynamic pricing strategies. [PUBLICATION ABSTRACT]",NA
+1223,Article,TECHNOLOGICAL CAPACITY DEVELOPMENT THROUGH OSS IMPLEMENTATION: THE CASE OF PUBLIC HIGHER EDUCATION INSTITUTIONS IN ETHIOPIA,"The Open Source Software (OSS) literature gives little attention to the study and practice of domain specific end-user OSS implementation in general and in the public sector of developing countries (DCs) in particular. This paper, however, investigates the trajectories of two OSS-based information systems (IS) implementation projects in a developing country (DC) context with the aim to uncover the practice-based learning and resource sharing evident among locally situated and globally dispersed developers and users. The result of the interpretative case study research shows that the OSS philosophy and practice of software development, implementation and ownership, facilitates for the emergence of practice-based learning from the sharing of implementation accounts and artifacts without sharing the same context of work. Thus, the paper argues in favor of an implementation approach that focuses on distributed practice-based experience, knowledge and resource sharing, and learning with the mediation of the information infrastructure in order to facilitate and sustain OSS-based IS implementation in DCs. The paper contributes both to the OSS and IS implementation literatures by showing the mechanisms of developing the technological capacity of indigenous groups and using the trans-situated learning model as a means to understanding the learning dynamics in OSS implementation.",NA

This research explicates the interpretations and subsequent actions of key stakeholder groups towards OSS during the implementation of an OSS-based IS in a public sector organization in Ethiopia. Drawing upon the technological frames analytical framework, the study shows that the key stakeholder groups interpreted openness of the software and the community model of software implementation differently leading them to entertain divergent actions. Users were keen to solving operational problems via readymade IS with a third party support, while the management and technologists were focusing on the strategic importance of OSS not only to their own organization but also to the nation in general. Perception differences led to alliance formation, political processes, and change of management style. The study shows that as multiple interrelated elements shape the technological frames of groups, the relationship between frame incongruence and implementation is also complex and contextual. The study proposes technological frame analysis as an integral part of OSS implementation and a carefully crafted intervention to harness frame incongruence, if any.",NA

The metabotropic glutamate receptors (mGlus) belong to family C of the G-protein-coupled receptors (GPCRs). The eight mGlus identified to date are classified into three groups based on their structure, preferred signal transduction mechanisms, and pharmacology (group I: mGlu(1) and mGlus; group II: mGlu(2) and mGlu(3); group III: mGlu(4), mGlu(6), mGlu(7), and mGlu(8)). Noncompetitive antagonists, also known as negative allosteric modulators (NAMs), of mGlus offer potential therapeutic applications in diseases such as pain, anxiety, gastresophageal reflux disease (GERD), Parkinson's disease (PD), fragile X syndrome, and addiction.

Within long-term environmental research (LTER) projects data on flows of individuals, chemical substances and other biotic and abiotic materials are collected by different project partners and institutions. This leads not only to different data bases, but also to incomparable data sets. Therefore, a virtual research environment (VRE) for research projects concerning environmental management should be worked out.

+1272,Article,A Hidden Markov Model of Developer Learning Dynamics in Open Source Software Projects,"This study develops a stochastic model to capture developer learning dynamics in open source software projects (OSS). A hidden Markov model (HMM) is proposed that allows us to investigate (1) the extent to which individuals learn from their own experience and from interactions with peers, (2) whether an individual's ability to learn from these activities varies as she evolves/learns over time, and (3) to what extent individual learning persists over time. We calibrate the model based on six years of detailed data collected from 251 developers working on 25 OSS projects hosted at Sourceforge. Using the HMM, three latent learning states (high, medium, and low) are identified, and the marginal impact of learning activities on moving the developer between these states is estimated. Our findings reveal different patterns of learning in different learning states. Learning from peers appears to be the most important source of learning for developers across the three states. Developers in the medium learning state benefit the most through discussions that they initiate. On the other hand, developers in the low and the high states benefit the most by participating in discussions started by others. While in the low state, developers depend entirely upon their peers to learn, whereas in the medium or high state, they can also draw upon their own experiences. Explanations for these varying impacts of learning activities on the transitions of developers between the three learning states are provided. The HMM is shown to outperform the classical learning curve model. The HMM modeling of this study contributes to the development of a theoretically grounded understanding of learning behavior of individuals. Such a theory and associated findings have important managerial and operational implications for devising interventions to promote learning in a variety of settings.",10.1287/isre.1100.0308

These formations are described as arrangements of different justificatory logics within a certain time frame or a certain group of actors motivating the use of free and open source software by referring to different potentialities.

This study examined discussion forums of an Open Source project in a particular specialized application domain--electronic medical records--to see how development roles are carried out, and by whom. We found through a qualitative analysis that the core developers in this system include doctors and clinicians who also use the product. We also found that the size of the community associated with the project is an order of magnitude smaller than predicted, yet still maintains a high degree of responsiveness to issues raised by users.

First we develop a requirements-based taxonomy of open-source projects and we discover patterns linking between this taxonomy and project success. We also propose a classification of requirement types based on their representativeness in open-source projects. This highlights the overall importance of various types of requirements in the context of open-source software development. We also identify exceptions defined as the unusually high frequency of a requirement type and explain them based on the specific domain addressed within the project containing the exception. Finally, we investigate the lifecycle of 16 open-source projects and discover and explain patterns of evolution for a number of requirement types.",NA

In that community, companies always play auxiliary roles, and integrate the result of OSS into their business activities. However, in the Eclipse open source software community, the main role of OSS development activities is taken over by companies. The relationship between individuals and companies is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of a company. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify a structure of co-creation in an OSS ecosystem led by companies considering the Eclipse community as one particular case. It also constructs a co-creation process model to promote sustainable development for an OSS ecosystem following two axes 1) value sharing and value acquisition, and 2) quantitative development and qualitative development. Some mechanisms that drive this process are embedded everywhere in the Eclipse ecosystem.",NA

+1284,Article,A comparative study of challenges in integrating Open Source Software and Inner Source Software,"Context: Several large software-developing organizations have adopted Open Source Software development (OSSD) practices to develop in-house components that are subsequently integrated into products. This phenomenon is also known as ``Inner Source{''}. While there have been several reports of successful cases of this phenomenon, little is known about the challenges that practitioners face when integrating software that is developed in such a setting. Objective: The objective of this study was to shed light on challenges related to building products with components that have been developed within an Inner Source development environment. Method: Following an initial systematic literature review to generate seed category data constructs, we performed an in-depth exploratory case study in an organization that has a significant track record in the implementation of Inner Source. Data was gathered through semi-structured interviews with participants from a range of divisions across the organization. Interviews were transcribed and analyzed using qualitative data analysis techniques. Results: We have identified a number of challenges and approaches to address them, and compared the findings to challenges related to development with OSS products reported in the literature. We found that many challenges identified in the case study could be mapped to challenges related to integration of OSS. Conclusion: The results provide important insights into common challenges of developing with OSS and Inner Source and may help organizations to understand how to improve their software development practices by adopting certain OSSD practices. The findings also identify the areas that need further research. (C) 2011 Elsevier B.V. All rights reserved.",10.1016/j.infsof.2011.06.007
+1288,InProceedings,A generic framework for stochastic dynamic simulation of chemical engineering systems using free/open source software,"Chemical engineering process modelling and simulation pose significant challenges to the computer program developer. Chemical processes are invariably described by non-linear equations such as chemical reaction kinetics, flow-pressure relationships and physical properties. Dynamic simulation of such systems involves the solution of sets of non-linear differential and algebraic equations. There is also uncertainty associated with the model equations themselves (model uncertainty), their parameters (parametric uncertainty) and the inputs into the model (input uncertainty). Tools that aid chemical engineers in the solution of these problems have been successfully commercialised and enjoy a measure of success, although the adoption of dynamic and stochastic simulation packages is lagging behind the steady-state flowsheeting tools. Commercial software solutions can be prohibitively expensive in addition to confining users to adhere to proprietary standards. The Free Software and Open Source movements have made inroads into providing non-proprietary alternatives to many commercial software packages, which has encouraged the adoption of open standards. This work presents a framework for the development of stochastic dynamic simulations of chemical processes using only free and open source software. The large problem of stochastic dynamic simulation has been broken down into stages: 1. Input modelling using Markov chain models trained on process data or seeded by hand in addition to stationary distribution models. This enables dynamic scenarios to be handled with the minimum of special case code generation. 2. Process modelling using an object-oriented approach in the Modelica language. Modelica has an actively developed open source implementation called OpenModelica and is an open standard modelling language. 3. Monte Carlo simulation using extensions to the OpenModelica compiler that ease parallel simulations 4. Postprocessing, including visualisation and statistical analysis. Statistics that are generated can be used for control evaluation purposes. The Tennessee-Eastman challenge process is used to illustrate its capabilities.",NA

However, many other popular languages such as XSL or XML have received minor attention. In this paper, we discuss some trends in OSS development that we observed when considering multiple programming language evolution of OSS. Based on the revision data of 22 OSS projects, we tracked the evolution of language usage and other artefacts such as documentation files, binaries and graphics files. In these systems several different languages and artefact types including C/C++, Java, XML, XSL, Makefile, Groovy, HTML, Shell scripts, CSS, Graphics files, JavaScript, JSP, Ruby, Phyton, XQuery, OpenDocument files, PHP, etc. have been used. We found that the amount of code written in different languages differs substantially. Some of our findings can be summarized as follows: (1) JavaScript and CSS files most often co-evolve with XSL; (2) Most Java developers but only every second C/C++ developer work with XML; (3) and more generally, we observed a significant increase of usage of XML and XSL during recent years and found that Java or C are hardly ever the only language used by a developer. In fact, a developer works with more than 5 different artefact types (or 4 different languages) in a project on average.",10.1145/1985441.1985447

+1291,Article,A theory-grounded framework of Open Source Software adoption in SMEs,"The increasing popularity and use of Open Source Software (OSS) has led to significant interest from research communities and enterprise practitioners, notably in the small business sector where this type of software offers particular benefits given the financial and human capital constraints faced. However, there has been little focus on developing valid frameworks that enable critical evaluation and common understanding of factors influencing OSS adoption. This paper seeks to address this shortcoming by presenting a theory-grounded framework for exploring these factors and explaining their influence on OSS adoption, with the context of study being small- to medium-sized Information Technology (IT) businesses in the U.K. The framework has implications for this type of business and, we will suggest, more widely as a frame of reference for understanding, and as tool for evaluating benefits and challenges in, OSS adoption. It also offers researchers a structured way of investigating adoption issues and a base from which to develop models of OSS adoption. The study reported in this paper used the Decomposed Theory of Planned Behaviour (DTPB) as a basis for the research propositions, with the aim of: (i) developing a framework of empirical factors that influence OSS adoption; and (ii) appraising it through case study evaluation with 10 U.K. Small- to medium-sized enterprises in the IT sector. The demonstration of the capabilities of the framework suggests that it is able to provide a reliable explanation of the complex and subjective factors that influence attitudes, subjective norms and control over the use of OSS. The paper further argues that the DTPB proved useful in this research area and that it can provide a variety of situation-specific insights related to factors that influence the adoption of OSS.

Many FLOSS projects have proven to be very successful, producing high quality products with steady and frequent releases. This study aims to identify FLOSS practices that can be adapted for the corporate environment. To achieve this goal, a framework to compare FLOSS and industrial development methodologies was created. Three successful FLOSS projects were selected as study targets (the Linux Kernel, the FreeBSD operating system, and the JBoss application server), as well as two projects from Ericsson, a large telecommunications company. Based on an analysis of these projects, FLOSS best practices were tailored to fit industrial development environments.

Drawing on research in information systems and sociology, this study develops and evaluates an integrated model for the acceptance of OSS. In addition to the traditional technology adoption variables the findings stress the importance of social identification as a key driver of OSS adoption. The proposed model provides a useful decision support tool for assessing and proactively designing interventions targeted at successful OSS adoption and diffusion. (C) 2010 Elsevier B.V.

In an earlier article, a proof-of-concept for a computer-aided visualization tool (also named STEVE, version 1.0) for stochastic theory education in water resources engineering was articulated {[}see, Schwenk et al. Comput. Appl. Eng. Educ., 2008, in press). Using lava Native Interfacing, it was shown that STEVE 1.0 could wrap a space time stochastic model written in any computer language and be independent of any specific language compiler during tool usage. This article describes the general philosophy, software design, and classroom usage for STEVE with significant improvements on visualization and user-friendliness (hence, rightfully called version 2.0). The software was created using the C++ programming language with the Microsoft Windows Applications Programming Interface (API). OpenGL was used for the visualization display, and the OpenGL Utility Toolkit (GLUT) was used to visualize text inside the OpenGL window. The instructor-specified simulation program on stochastic theory was written in Fortran 77. The application has user-friendly options for modifying input data and parameter specifications as desired by the instructor or the student user. STEVE 2.0 has been tested with the Windows XP and Windows Vista operating systems. For the benefit of interested users and software makers, we also provide the software application, a short tutorial and all pertinent source codes as freeware for download on our STEVE homepage at http://iweb.tntech.edu/saswe/steve.html.

We present occupancy and patient scheduling models to help address these challenges. These patient flow models can be used to explore the relationship between procedure scheduling practices and the resulting occupancy on inpatient obstetrical units such as labor and delivery and postpartum. The models capture numerous important characteristics of inpatient obstetrical patient flow such as time of day and day of week dependent arrivals and length of stay, multiple patient types and clinical interventions, and multiple patient care units with inter-unit patient transfers. We have used these models in several projects at different hospitals involving design of procedure scheduling templates and analysis of inpatient obstetrical capacity. In the development of these models, we made heavy use of open source software tools and have released the entire project as a free and open source model and software toolkit.[PUBLICATION ABSTRACT]",10.1007/s10729-010-9141-8

Several software tools for drawing and editing compound structures are available, but they lack options for automatic generation of chemical libraries. We have implemented ChemT, an easy-to-use open-source software tool that automates the process of preparing custom-made template-based chemical libraries. ChemT automatically generates three-dimensional chemical libraries by inputting a chemical template and the functional groups of interest. The graphical user interface of ChemT is self-explanatory, and a complete tutorial is provided. Several file formats are accepted by ChemT, and it is possible to filter the generated compounds according to different physicochemical properties. The compounds can be subject to force field minimization, and the resulting three-dimensional structures recorded on commonly used file formats. ChemT may be a valuable tool for investigators interested in using in silico virtual screening tools, such as quantitative structure-activity relationship modelling or molecular docking, in order to prioritize compounds for further chemical synthesis.

We examined 12 FOSS projects: 4 small, 4 medium and 4 large, where size was determined by number of code contributors. First, we found that contrary to what has been reported from studies of individual large projects like Mozilla and Eclipse, duplicate bug reports are a problem for FOSS projects, especially medium-sized, which struggle with a large number of submissions without the resources of large projects. Second, we found that the focus of a project does not affect the number of duplicate bug reports. Our findings indicate a need for additional scaffolding and training for bug reporters.",NA

According to software engineering folklore, the architecture and the organization of software depend on the communication patterns of the contributors. Communication patterns among developers influence knowledge sharing among them. Unlike in a formal organization, the communication network structures in an OSS project evolve unrestricted and unplanned. We develop a non-cooperative game-theoretic model to investigate the network formation in an OSS team and to characterize the stable and efficient structures. Developer heterogeneity in the network is incorporated based on their informative value. We find that there may exist several stable structures that are inefficient and there may not always exist a stable structure that is efficient. The tension between the stability and efficiency of structures results from developers acting in their self-interest rather than the group interest. Whenever there is such tension, the stable structure is either underconnected across types or overconnected within type of developers from an efficiency perspective. We further discuss how an administrator can help evolve a stable network into an efficient one. Empirically, we use the latent class model and analyze two real-world OSS projects hosted at SourceForge. For each project, different types of developers and a stable structure are identified, which fits well with the predictions of our model. Overall, our study sheds light on how developer abilities and incentives affect communication network formation in OSS projects. [PUBLICATION ABSTRACT]",NA

With dual licensing, a firm releases the same software product under both a traditional proprietary license and an open source one. We show that the decision to employ a dual licensing strategy occurs whenever the feedbacks of the open source community are valuable enough compared to the quality of the software that the firm is able to develop in-house. Our analysis points to the central role of an appropriate managing of OS licenses in order to balance the pros and cons of ``going open source{''} and to make this versioning strategy viable for software vendors; our analysis also suggests a possible explanation for the observed proliferation of open source licenses.

In addition to this it identifies features that are considered as important in such large Information Systems, and how they relate to Open Source Software adoption in the context of the public sector in Sri Lanka. The findings are analyzed and suitable recommendations are presented for better selection of software in the public sector. The work is important as it identifies and highlights factors that affect the choice of software in the public sector. This is important for several categories of people. It is of importance to the strategic management and policy makers to know what drives the information system procurement decisions in order to make more relevant policies and guidelines that are congruent with the needs in government sector departments. It is useful when advocating new technologies and information systems. This is especially true when advocating the use of Free and Open Source software for the use in the public sector in a wholesome and sustainable manner. The research is also important to software vendors and solution providers to the public sector in identifying what factors need to be taken in to account when bidding for public sector IS projects. The research is of a qualitative nature. It consists of multiple case studies of selected government sector departments and projects in Sri Lanka. The study investigates information systems developed by internal staff, developed by external consultants, procured systems, system implementation via private public partnerships (PPP) and projects guided by the Information and Communication Technology Agency (ICTA) of Sri Lanka.

Due to the steady fluctuation of the software developers merely temporary teams and an unforced community of users result. Their feedback and loyalty to the software project are mainly based on individual benefit but may also be motivated by idealism. From our point of view, civil engineering has a broad base to use software development as an interface between education and profession.

In so doing, the initial goals of free software advocates are being dramatically expanded to include broader aims of digital freedom and social justice. Utilizing the concept of social movements from political sociology, this article first outlines the key aims and discourses surrounding the free software movement by discussing the emergence and development of F/OSS efforts such as the GNU/Linux operating system and the GNU Public License (GPL). Second, I provide examples of how the free software discourses have been adopted, altered, and expanded by a number of organized groups over the past decade. These groups, such as the Creative Commons, digital privacy advocates, and global development agencies, have adopted some of the core concepts of free software, while greatly expanding their meaning and purpose to suit their own advocacy aims. Finally, I argue that the adoption of free software discourse among these newer groups is also having a recursive effect upon the free software movement by encouraging free software advocates to conceptualize F/OSS as part of a broader movement of digital rights and social justice. In the conclusion, the prospects for the emergence of a larger technological and cultural freedom movement in the future are assessed.",10.1080/19331681.2011.592080

+1371,Article,IceLuva: A Scripting Framework for MR Image Reconstruction Based on Free Software,"Image reconstruction is an essential part of the magnetic resonance imaging process, and a whole field of research is dedicated to the development of reconstruction algorithms. For this reason, scanner manufacturers provide researchers with programming frameworks that give full control over the whole procedure. The drawback is that these environments are complex, and the code is non-portable and covered by non-disclosure agreements. In this article, a simplified framework based on a free scripting language (Lua) is presented. It is oriented to the development of postprocessing algorithms that are seamlessly integrated with the pipeline of a commercial scanner. The structure privileges simplicity over performance, to be quickly learned and used by researchers and students who might not be acquainted with low-level programming languages. Common postprocessing algorithms (contrast modulation, pixelwise fitting, phase-contrast imaging) could be implemented with similar to 100 logical lines of code or less, using a syntax that is similar to the Matlab programming language. The average performance of the reconstruction was lower with respect to the native implementation, but superior to offline postprocessing on a desktop computer, without the bottleneck of offline data export.

Many OSS projects are composed of a mix group of firm-paid and volunteer developers, with different motivations, collaboration practices and working styles. As OSS development consists of collaborative works in nature, it is important to know whether these differences have an impact on collaboration between difference types of stakeholders, which lead to an influence in the project outcomes. In this paper, we empirically investigate the firm-paid participation in resolving OSS evolution issues, the stakeholder collaboration and its impact on OSS issue resolution time. The results suggest that though a firm-paid assigned developer resolves much more issues than a volunteer developer does, there is no difference in issue resolution time between them. Besides, the more important factor that influences the issue resolution time comes from the collaboration among stakeholders rather than from individual characteristics.",NA

Until now however, there are few reports of public organizations actually adopting OSS ERP systems. This study aims to use case study research to increase the understanding of the public sectors' low adoption rate and the factors that impact the intentions to adopt an OSS ERP system. The results indicate that the system's functionality is essential; OSS ERP systems are not perceived as fully developed for large organizations such as municipalities. Neither is the OSS consultancy market considered mature enough.

Different approaches for introducing usability activities into SW development have not yet been evaluated with respect to open source software (OSS). This paper tests the introduction of usability activities through four empirical case studies in the OSS development context. Case studies were carried out using four OSS projects that were not commercially supported. Empirical analysis suggests that usability specialists should become members of the OSS community, but, at the same time, should keep an objective view. The usability activities had substantially more impact when specialists introduced and carried them out as fellow members of the OSS community than as usability consultants from outside the community. The importance of management commitment for usability activities is discussed in the OSS context. The challenge of adapting usability and OSS development philosophies together should be researched further. [PUBLICATION ABSTRACT]",NA

Thus, the obligatory use of free software in public administration was ordained to promote the opportune and efficient rendering of public services, since this technology is included as an instrument for the above-mentioned tasks. For example, the Ministry of Popular Power for Internal Relations and Justice, through the Autonomous Service of Registries and Notaries and the emission of decrees and laws that govern the corresponding competence, such as Presidential Decree 3.390 (Presidency of the Republic, 2004), has implemented modernization through the automation of registry and notary processes by employing electronic means in which free software has a place. Interest has arisen in establishing an effective legal application for the public function developed by Registries and Notaries by implementing such an IT migration.

The fast growth of OSS movement has impressed us with reduced cost but high quality software. To learn some lessons from successful OSS in handling the complexity, social network analysis is prevalent in analyzing both human-aspect and source-code-aspect interaction of OSS. This paper conducted an empirical study of an OSS project-ArgoUML. Unlike most previous studies regarding OSS email archives as a whole social network, our focus is on the quantitative analysis of a series of social networks produced in the process of OSS version evolution and module development.Through the empirical study, we have found that all the social network measures employed in this study are comparable to identify core developers of ArgoUML project. The frequency of co-occurrence of developers within the same topic is not a decisive factor to identify core developers. Developers within the same module communicate closely and frequently with each other. The more modules a developer developed, the more communication he (or she) will have with other developers.

It draws on a study of online observation of a virtual community, i.e. an open source software (OSS) community. The paper examines general and specific advantages and disadvantages of the observer roles in online settings by relating these roles to the same roles assumed in offline settings. The study suggests that under the right circumstances online and offline observation may benefit from being combined as they complement each other well. Quality issues and factors important to elicit trustworthy observational data from online study settings, such as OSS communities, are discussed. A proposition is made concerning how threats to credibility and transferability in relation to online observation (i.e. lack of richness and detail, risk of misunderstandings) can be diminished, while maintaining the level of dependability (which is potentially high due to a greater degree of anonymity and ""isolation"" in online settings). The paper thus suggests that the less participative the researcher's online observer role is, the more s/he should consider introducing offline data collection techniques rather than adopting a more participative role in the observed online setting. This methodological discussion forms the basis for making a well-considered choice of online observer role rather than passively sliding into a role assigned by the setting.

More recently, software evolution researchers have investigated logical dependencies between artifacts to assess failure-proneness, detect design issues, infer code decay, and predict likely changes. However, the interplay between these two kinds of dependencies is still obscure. By mining 150 thousand commits from the Apache Software Foundation repository and employing object-oriented metrics reference values, we concluded that 91% of all established logical dependencies involve non-structurally related artifacts. Furthermore, we found some evidence that structural dependencies do not lead to logical dependencies in most situations. These results suggest that dependency management methods and tools should rely on both kinds of dependencies, since they represent different dimensions of software evolvability.",10.1109/SBES.2011.39

+1402,Article,Open Source software and social networks: Disruptive alternatives for medical imaging,"In recent decades several major changes in computer and communication technology have pushed the limits of imaging informatics and PACS beyond the traditional system architecture providing new perspectives and innovative approach to a traditionally conservative medical community. Disruptive technologies such as the world-wide-web, wireless networking, Open Source software and recent emergence of cyber communities and social networks have imposed an accelerated pace and major quantum leaps in the progress of computer and technology infrastructure applicable to medical imaging applications. Methods: This paper reviews the impact and potential benefits of two major trends in consumer market software development and how they will influence the future of medical imaging informatics. Open Source software is emerging as an attractive and cost effective alternative to traditional commercial software developments and collaborative social networks provide a new model of communication that is better suited to the needs of the medical community. Observations: Evidence shows that successful Open Source software tools have penetrated the medical market and have proven to be more robust and cost effective than their commercial counterparts. Developed by developers that are themselves part of the user community, these tools are usually better adapted to the user's need and are more robust than traditional software programs being developed and tested by a large number of contributing users. This context allows a much faster and more appropriate development and evolution of the software platforms. Similarly, communication technology has opened up to the general public in a way that has changed the social behavior and habits adding a new dimension to the way people communicate and interact with each other. The new paradigms have also slowly penetrated the professional market and ultimately the medical community. Secure social networks allowing groups of people to easily communicate and exchange information is a new model that is particularly suitable for some specific groups of healthcare professional and for physicians. It has also changed the expectations of how patients wish to communicate with their physicians. Conclusion: Emerging disruptive technologies and innovative paradigm such as Open Source software are leading the way to a new generation of information systems that slowly will change the way physicians and healthcare providers as well as patients will interact and communicate in the future. The impact of these new technologies is particularly effective in image communication, PACS and teleradiology. (C) 2010 Elsevier Ireland Ltd. All rights reserved.",10.1016/j.ejrad.2010.05.004

+1406,Article,"Open source software licenses: Strong-copyleft, non-copyleft, or somewhere in between?","Studies on open source software (OS) have shown that the license under which an OSS is released has an impact on the success or failure of the software. In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

However, this notion became more complicated, once the future grew out to be a present with huge bundle of innovative technologies, Internet capabilities, communication possibilities, and ease in life. A major step of moving from a product phone to a smart phone, eventually to a mobile device has created a new industry with humongous potential for further developments. The current mobile platform market is witnessing a platforms-war with big players such as Apple, Google, Nokia and Microsoft in a major role. An important aspect of today's mobile platform market is the contributions made through open source initiatives which promote innovation. This paper gives an insight into the open-source software strategies of the leading players and its implications on the market. It first gives a precise overview of the past leading to the current mobile platform market share state. Then it briefs about the open-source software components used and released by Apple, Google and Nokia platforms, leading to their mobile platform strategies with regard to open source. Finally, the paper assesses the situation from the point of view of communities of software developers complementing each platform. The authors identified relevant implications of the open-source phenomenon in the mobile-industry.",NA

Different algorithms have been implemented to perform single and multi-conformation superimpositions on one or more templates. Alignments can be accomplished by matching pharmacophores, heavy atoms or a combination of the two. All methods have been successfully validated on eight comprehensive datasets previously gathered by Sutherland and co-workers. High computational performance has been attained through efficient parallelization of the code. The unsupervised nature of the alignment algorithms, together with its scriptable interface, make Open3DALIGN an ideal component of high-throughput, automated cheminformatics workflows.",10.1007/s10822-011-9462-9

+1417,InCollection,OpenMS and TOPP: Open Source Software for LC-MS Data Analysis,"Proteomics experiments based on state-of-the-art mass spectrometry produce vast amounts of data, which cannot be analyzed manually. Hence, software is needed which is able to analyze the data in an automated fashion. The need for robust and reusable software tools triggered the development of libraries implementing different algorithms for the various analysis steps. OpenMS is such a software library and provides a wealth of data structures and algorithms for the analysis of mass spectrometric data. For users unfamiliar with programming, TOPP ({''}The OpenMS Proteomics Pipeline{''}) offers a wide range of already implemented tools sharing the same interface and designed for a specific analysis task each. TOPP thus makes the sophisticated algorithms of OpenMS accessible to nonprogrammers. The individual TOPP tools can be strung together into pipelines for analyzing mass spectrometry-based experiments starting from the raw output of the mass spectrometer. These analysis pipelines can be constructed using a graphical editor. Even complex analytical workflows can thus be analyzed with ease.",10.1007/978-1-60761-987-1\\_23

+1419,Article,PaDEL-Descriptor: An Open Source Software to Calculate Molecular Descriptors and Fingerprints,"Introduction: PaDEL-Descriptor is a software for calculating molecular descriptors and fingerprints. The software currently calculates 797 descriptors (663 1D, 2D descriptors, and 134 3D descriptors) and 10 types of fingerprints. These descriptors and fingerprints are calculated mainly using The Chemistry Development Kit. Some additional descriptors and fingerprints were added, which include atom type electrotopological state descriptors, McGowan volume, molecular linear free energy relation descriptors, ring counts, count of chemical substructures identified by Laggner, and binary fingerprints and count of chemical substructures identified by Klekota and Roth. Methods: PaDEL-Descriptor was developed using the Java language and consists of a library component and an interface component. The library component allows it to be easily integrated into quantitative structure activity relationship software to provide the descriptor calculation feature while the interface component allows it to be used as a standalone software. The software uses a Master/Worker pattern to take advantage of the multiple CPU cores that are present in most modern computers to speed up calculations of molecular descriptors. Results: The software has several advantages over existing standalone molecular descriptor calculation software. It is free and open source, has both graphical user interface and command line interfaces, can work on all major platforms (Windows, Linux, MacOS), supports more than 90 different molecular file formats, and is multithreaded. Conclusion: PaDEL-Descriptor is a useful addition to the currently available molecular descriptor calculation software.

User participation is becoming a relevant topic of research in the OSS development context. Though it has not been examined much to date, the OSS development context has been argued to advocate a particular type of participatory design, which can now be scrutinised in its natural setting as it evolves. Two interpretive case studies on user participation in OSS development are included in this article. The first examines a traditional community OSS development project; the second concentrates on the company OSS development context, the case being a software development unit of a global corporation involved in OSS development. Through analysis of the cases, different forms of participatory design (PD), especially of distributed PD, are identified. Distributed PD is interpreted to include gaining an understanding of users' current practices, redesigning them together with users and gathering feedback from users related to the solutions. Different kinds of roles are available to users, as well as to for intermediaries `representing users'. Especially, the importance of online forum-based and intermediary-driven PD is emphasised in this article. Implications for PD and OSS research and practice are considered.",10.1080/0144929X.2010.503351

+1425,Article,Predicting OSS Development Success: A Data Mining Approach,"Open Source Software (OSS) has reached new levels of sophistication and acceptance by users and commercial software vendors. This research creates tests and validates a model for predicting successful development of OSS projects. Widely available archival data was used for OSS projects from Sourceforge. net. The data is analyzed with multiple Data Mining techniques. Initially three competing models are created using Logistic Regression, Decision Trees and Neural Networks. These models are compared for precision and are refined in several phases. Text Mining is used to create new variables that improve the predictive power of the models. The final model is chosen based on best fit to separate training and validation data sets and the ability to explain the relationship among variables. Model robustness is determined by testing it on a new dataset extracted from the SF repository. The results indicate that end-user involvement, project age, functionality, usage, project management techniques, project type and team communication methods have a significant impact on the development of OSS projects.",10.4018/jismd.2011100102

But mobilizing the necessary forces in government to procure open source software has proven difficult. This article highlights the factors that instigate and carry through the adoption of open source in government: an external trigger; an emphasis on strategic goals; an information technology staff with sufficient dedication, technical sophistication, and creativity to make the transition; and high-level support at the policy-making level.

Based on the generated networks, similarities among projects and among developers are calculated, and projects (or developers) are clustered through their measured similarities.

If those descriptions are overly long or complex, then sharing their details may not be informative. OURMINE is a scripting environment for the development and deployment of data mining experiments. Using OURMINE, data mining novices can specify and execute intricate experiments, while researchers can publish their complete experimental rig alongside their conclusions. This is achievable because of OURMINE's succinctness. For example, this paper presents two experiments documented in the OURMINE syntax. Thus, the brevity and simplicity of OURMINE recommends it as a better tool for documenting, executing, and sharing data mining experiments.

+1432,Article,Socialization in Open Source Software Projects: A Growth Mixture Modeling Approach,"The success of open source software (OSS) projects depends heavily on the voluntary participation of a large number of developers. To remain sustainable, it is vital for an OSS project community to maintain a critical mass of core developers. Yet, only a small number of participants (identified here as ``joiners'') can successfully socialize themselves into the core developer group. Despite the importance of joiners' socialization behavior, quantitative longitudinal research in this area is lacking. This exploratory study examines joiners' temporal socialization trajectories and their impacts on joiners' status progression. Guided by social resource theory and using the growth mixture modeling (GMM) approach to study 133 joiners in 40 OSS projects, the authors found that these joiners differed in both their initial levels and their growth trajectories of socialization and identified four distinct classes of joiner socialization behavior. They also found that these distinct latent classes of joiners varied in their status progression within their communities. The implications for research and practice are correspondingly discussed.",10.1177/1094428110375002

My dissertation focuses on the relationships between developers in large open source projects and how software affects and is affected by these relationships. Fortunately, source code repository histories, mailing list archives, and bug databases from OSS projects contain latent data from which we can reconstruct a rich view of a project over time and analyze these sociotechnical relationships.

+1441,Article,Supporting software evolution in component-based FOSS systems,"FOSS (Free and Open Source Software) systems present interesting challenges in system evolution. On one hand, most FOSS systems are based on very fine-grained units of software deployment - called packages - which promote system evolution; on the other hand, FOSS systems are among the largest software systems known and require sophisticated static and dynamic conditions to be verified, in order to successfully deploy upgrades on users' machines. The slightest error in one of these conditions can turn a routine upgrade into a system administrator's nightmare. In this paper we introduce a model-based approach to support the upgrade of FOSS systems. The approach promotes the simulation of upgrades to predict failures before affecting the real system. Both fine-grained static aspects (e.g. configuration incoherences) and dynamic aspects (e.g. the execution of configuration scripts) are taken into account, improving over the state of the art of upgrade planners. The effectiveness of the approach is validated by instantiating the approach to widely-used FOSS distributions. (C) 2010 Elsevier B.V. All rights reserved.",10.1016/j.scico.2010.11.001

It is very crucial for companies to have fast and accurate access to mission-critical business information in order to maintain its competitiveness. The ability to establish network connections between the existing systems becomes a must in order to optimize the use of critical information. To realize this, the implementation of system integration looks promising. However, system integration process is not an easy task because it involves variety of systems with different organizations backgrounds. The main objective of this paper is to propose an integration model that is generic and easily adapted by many organizations. The Information Management Division, Public Sector Department in Malaysia is chosen as a case study. The systems used in this department will be analyzed and problems faced will be identified. Research methodology conducted includes the Analysis Phase, Design Phase, Development Phase and Testing Phase.

This in turn is influenced by three types of social capital - relational capital, cognitive capital and structural capital. In addition, this study also examines two moderating effects - the impact of technical complexity on the relationship between cognitive capital and expertise integration, and of task interdependence on the relationship between expertise integration and task completion. Through a field survey of 160 OSS members from five Taiwanese communities, there is support for some of the proposed hypotheses. Both reciprocity and centrality affect expertise integration as expected, but the influence of commitment and cognitive capital (including expertise and tenure) on expertise integration is not significant. Finally, expertise integration affects both team size and team effort, which in turn jointly influence task completion. This research contributes to advancing theoretical understanding of the effectiveness of free OSS development as well as providing OSS practitioners with insight into how to leverage social capital for improving the performance of OSS development.",10.1111/j.1365-2575.2009.00347.x

+1459,Article,The search for a research method for studying OSS process innovation,"Medium-sized, open-participation Open Source Software (OSS) projects do not usually perform explicit software process improvement on any routine basis. It would be useful to understand how to get such a project to accept a process improvement proposal and hence to perform process innovation. We want to determine an effective and feasible qualitative research method for studying the above question. We present (narratively) a case study of how we worked towards and eventually found such a research method. The case involves four attempts at collecting suitable data about innovation episodes (direct participation (twice), polling developers for episodes, manually finding episodes in mailing list archives) and the adaptation of the Grounded Theory data analysis methodology. Direct participation allows gathering rather rich data, but does not allow for observing a sufficiently large number of innovation episodes. Polling developers for episodes did not prove to be useful. Using mailing list archives to find data to be analyzed is both feasible and effective. We also describe how the data thus found can be analyzed based on the Grounded Theory Method with suitable adjustments. By-and-large, our findings ought to apply to studying various phenomena in OSS development processes that are similarly heavyweight and infrequent. However, specific details may block this possibility and we cannot predict which details that might be. The amount of effort involved in direct participation approaches to qualitative research can easily be underestimated. Also, survey approaches are not well-suited for many process issues in OSS, because too few developers are sufficiently process-conscious. An approach based on passive observation is a viable alternative in the OSS context due to the availability of large amounts of fairly complete archival data.",10.1007/s10664-011-9160-1

Our results are from the matching between the informational needs of 23 OSS selectors from diverse software-intensive organizations, and the in-depth study of 9 OSS communities of different sizes and domains. The results evidenced specific areas of improvement that might help to enhance the industrial OSS selection practice.",NA

The web pages of OSS products are the main communication channel with potential users and they should act as a product's shopping window. However, even the home pages of well-known OSS products show technicalities and details that are not relevant the vast majority of users. So, final users and even developers, who are interested in evaluating and potentially adopting an OSS product, are often negatively impressed by the web portal of the product and turn to proprietary software solutions or fail to adopt OSS that may be useful in their activities.",10.1145/2181101.2181109

In contrast to industry, where reviews are typically assigned to specific individuals, changes are broadcast to hundreds of potentially interested stakeholders. Despite concerns that reviews may be ignored, or that discussions will deadlock because too many uninformed stakeholders are involved, we find that this approach works well in practice. In this paper, we describe an empirical study to investigate the mechanisms and behaviours that developers use to find code changes they are competent to review. We also explore how stakeholders interact with one another during the review process. We manually examine hundreds of reviews across five high profile OSS projects. Our findings provide insights into the simple, community-wide techniques that developers use to effectively manage large quantities of reviews. The themes that emerge from our study are enriched and validated by interviewing long-serving core developers.",10.1145/1985793.1985867

An Exploratory Study of Documentation in FLOSS Teams,"Organizations bring together people with various access to and understanding of the work at hand. De-spite their different stocks of background knowledge, most of them engage in documentation, whether as writers or readers. This paper explores how documents serve such diverse users by building a framework articulating the characteristics of documents supporting collaborators with asymmetric access to knowledge versus people with symmetric knowledge. Drawing on document-centric approaches we hypothesize that documents supporting asymmetric groups are likely to be more prescriptive and explicate their own use compared to documents supporting symmetric groups. Through exploratory analysis of two kinds of documents, used across three FLOSS projects, we find that documents supporting collaborators with asymmetric knowledge do appear to explicate their own use in more detail. They do so by prescribing their own 1) purpose, 2) context of use, 3) content and form in greater detail than documents used by core community members with symmetric access to project knowledge.",10.1109/HICSS.2011.492

Within the context of a knowledge-based economy, this sort of approach appears exemplary for a growing number of industrial activities in which the amount of knowledge that has to be mastered is too large for a single agent, however powerful. Considering knowledge as a mutual resource requires a rethinking of the value chain concept, since cash flow is derived from use of the knowledge base (services, complementary products), not from the knowledge itself. In a classical industrial economics perspective, this reshaping of the value chain must be analyzed not only at the global ecosystem level (who produces what, between firms and universities, users and producers, etc.), but also at the industrial level (once the industry's role has been identified, how does it organize itself?). In this article, we argue for a more structured and global analysis, based on the tools of industrial economics, and thus starting from the basic conditions of the computer market and of the buyers' competence in software development (the ""dominant user's skill"").",NA

+1485,InProceedings,A Novel Approach to Increase Efficiency of OSS/BSS Workflow Planning and Design,"Nowadays, communication technologies and the range of mobile operator services are changing extremely fast. This results in the need for constant adaptation and expansion of OSS/BSS1 used in mobile operator networks. Currently, adaptation and expansion strategies are poorly formalized and validated. In current state-of-the-art approaches, several iterations involving analysts and system architects are necessary, resulting in time and money consuming service development. The workflow design method proposed in this paper fills this gap. It employs a well-defined workflow and analysis model for developing and adapting OSS/BSS. The applicability of this novel approach is confirmed by a prototypically implemented design software tool which has been tested in a telecommunication enterprise. The developed tool provides automation of service planning, computational independent workflow design and its transformation into its realization model.

+1489,Article,A limited revolution - The distributional consequences of Open Source Software in North America,"Open Source Software (OSS) has become an important alternative method of organizing the production of software and has gained in popularity and use because of its benefits and costs relative to the dominant proprietary software model. In this paper, I use evidence from the United States and Canada to examine the distribution of these benefits and costs. I argue that although the rhetoric surrounding OSS is supported empirically, the benefits of OSS have been limited because of the way this technological project has evolved within its associated policy environment. That is, although ostensibly neutral, the policies and laws of both the U.S. and Canadian governments have tended to be positioned implicitly against the use of OSS both in the public sector and in the economy generally. In addition, OSS use and development requires a set of skills that are absent in many instances or create prohibitively high costs. Thus OSS is typically used by larger organizations, and its development is restricted to a mostly male, highly educated, high-income group of contributors. Therefore while the benefits of OSS are real, the distribution of these benefits is skewed. (C) 2011 Elsevier Inc. All rights reserved.",10.1016/j.techfore.2011.10.003

However, in the Eclipse OSS community, the main role of OSS development activities is taken over by vendors. The relationship between individuals and vendors is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of vendors. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify internal and external structures in an OSS ecosystem led by vendors considering the Eclipse community as one particular case.

+1496,Article,ACTIVITY OF YUGOSLAV SECTIONS OF THE AMERICAN OFFICE OF STRATEGIC SERVICES (OSS) IN NORTH AFRICA AND SOUTHERN ITALY,"From the outbreak of the war, the United States strove to establish a modern and efficient intelligence service. First, they founded the Coordination of Information (COI) and subsequently, the Office of Strategic Services - OSS), naming General William Donovan as head of both. Right from the establishment of OSS, Donovan wanted to expand its operations to North African and Mediterranean battlefields in order for the American intelligence service to be able to direct special operations against the Axis Powers in Yugoslavia from there. The setting up of the bases required a considerable amount of effort and negotiation with the British secret services, as they were used to defending their own interests and leading intelligence position in the Balkans and would not permit the OSS to operate independently in Yugoslavia. Donovan thus established bases in Cairo and Bari, with a Yugoslav section operating within each. The principal tasks of the two sections were to train the personnel to be sent to Yugoslavia, to gather intelligence about Yugoslavia, organise assistance and support for Yugoslav resistance movements and compile intelligence obtained by the OSS from its missions from the occupied Yugoslav territory. Aided initially by the government in exile and later on by Partisan representatives in southern Italy, the Yugoslav sections trained numerous Yugoslays many of who were Slovenes and sent them back to Yugoslavia. These worked as wireless operators, cryptographers and interpreters mostly between Slovene and Croatian Partisans. Some Slovenes, American Slovenes in particular, carried out the functions of mission chiefs or instructors in the Yugoslav sections of the OSS. Although collaborators with the American intelligence service made important contribution to the common struggle against the Axis Powers, they were branded by the Partisan leadership towards the end of the war and after it for having worked with the Americans. Following the Tehran Conference in December 1943, the supply of aid for the resistance movements was directed to support the Partisan movement. Towards the end of the war and with the growth of the National Liberation Movement (NOG) in Yugoslavia, the role of the Yugoslav section gradually diminished It can be concluded that the activities of the Yugoslav sections in Cairo and Bari significantly influenced the development of resistance movements in Yugoslavia and Slovenia, both in terms of organising aid as well as training and sending the American missions to Yugoslavia.",NA

Models used in open software development are innovative in several ways, to the point that they are only recognized as valid models at all since they have actually produced mature and stable software more in a swift fashion. Some studies attempt to answer the OSS's development model, way to produce the quality products and distributed development model driven by motivated voluntary developers found in OSS. However, they are usually focused on handful projects and often miss to represent the whole world of OSS development. We analyze FLOSSMetrics database and SourceForge repository. By examining these, we attempt to identify 1) factual landscape of OSS projects, 2) correlation between different measures including developers' activities and consumers' interests. This analysis is also supplemented by empirical research on world re-known OSS projects to identify the implication of vendor-led OSS projects. We find that OSS projects are hardly to be seen as loci of future open innovation in several ways. We also conclude that prior belief which altruistic developers donating time and effort for the common good is highly romanticized view of open source software.",NA
+1498,Article,Adoption of free/libre open source software in public organizations: factors of impact,"Purpose - In this paper the authors aim to investigate the importance of factors for the adoption of free/libre open source software (FLOSS) in the public sector. They seek to evaluate how different factors impact during the initiation and implementation phases of the adoption process. Design/methodology/approach - The authors base the methodological approach on two exploratory case studies with a contrasting result logic. They build a multi-level framework grounded both on literature review, and feedback from stakeholders. They then apply the framework to two case studies to better frame the findings. They consider phases of adoption (initiation, implementation) and the levels of adoption (technological, organizational, environmental, individual). Findings - In the case studies, the authors found the importance of a strong and decision-centric management board to give the impulse for the initiation phase of the process. As perceived by the stakeholders, a strong governmental support is of paramount importance to increase the adoption at the public level, although in the case studies examined the initiation stage started from the impulse of a championing management. Both case studies passed the initiation phase successfully. Continuous employees' training, organizational objectives consensus, and business process reengineering have been found important for the implementation phase. In the case study in which these factors were not in place, the implementation phase of adoption failed. Environmental factors - although relevant for the initiation of the adoption process - are less significant during the actual implementation of the adoption process, as the contrasting result logic from the case studies shows. Research limitations/implications - The study refers to two public organizations in a specific environmental setting. No causality among factors has been inferred. Quantitative objective data have been used to determine the success of adoption, for qualitative data multiple sources have been used when possible to limit threats to validity. Practical implications - The framework can be used by stakeholders in public organizations to better frame their adoption strategies and to compare results across institutions. Lessons learnt from the case studies can be useful to drive future adoptions of FLOSS. Originality/value - The framework combines phases of adoption and levels making it possible to frame the analysis of the case studies. It has been operationalized with a set of metrics, and with a protocol for the case studies to increase replicability value.",10.1108/09593841211232677
+1502,Article,Adoption of open source software in organizations: A socio-cognitive perspective,"Open source software (OSS) is an important trend in the information technology adoption landscape. It has received considerable attention in the scientific literature, but mostly in the professional press. In fact, there is much debate over its actual commercial and organizational value. Since the public discourse accompanying an IT may influence adoption decisions, it is important to consider IT specialists' perceptions of the discourse on OSS. In this study, we investigated the relationship between IT specialists' profiles, IT specialists' reception of the public discourse on OSS, and their organizations' receptivity to OSS. Drawing on the socio-cognitive perspective of IT innovation adoption and the organizing vision theory, a survey of 271 IT specialists was conducted to examine these issues. Our results indicate that a majority of IT specialists in our sample are rather neutral about the OSS concept conveyed in the public discourse. However, our sample also comprises respondents with more extreme perceptions who can be classified as either supporters or detractors. Our results indicate that detractors have more years of experience but have been less exposed to OSS than supporters, and that IT specialists' perceptions of the OSS concept are positively associated with their organizations' openness to OSS adoption and, to a lesser extent, with the existence of an organizational policy that favors OSS adoption. Altogether, our findings provide strong support for the organizing vision theory and the idea that the popularity of an IT innovation concept favors the adoption of the material IT innovation in organizations. By providing a preliminary test of a nomological network of IT specialists' perceptions of the OSS concept, our study offers insights as to why organizations may or may not take OSS into account in their software procurement decisions.

The perspective of enterprise users who use and pay for OSS has been largely neglected so far. Understanding what paying customers want and how to create products and services they value is the cornerstone of any business model. Therefore, research on what enterprise users value in OSS is of paramount importance to OSS solution suppliers; it can be used to create a new customer base and sustain an existing one. This study examines the value of OSS as perceived by enterprise customers. Through an analysis of three literature streams (firm participation in open source software, business models, and customer value), a model on customer value creation was developed. Interviews were conducted with nine decision makers from enterprises that use OSS in operational projects. The key findings of this research are that: i) the maturity of the software determines the degree to which customers value their relationship with the supplier; ii) customers value differentiating functionality and costs savings; and iii) switching costs with OSS depend on the size, complexity, and dependencies of the software itself. This research identifies the points of value that the suppliers of OSS should focus on, and it points to the need for marketing strategies that can demonstrate this value to enterprise customers.",NA

This procedure is even more emerging when we refer to open source software, where the need for shared knowledge is crucial for the maintenance and evolution of the code. A paradigm of open source project where code quality is especially important is the scientific language R. This paper aims to perform measurements on the R statistical open source software, examine the relationships among the observed metrics and special attributes of the R software and search for certain characteristics that define its behavior and structure. For this purpose, a random sample of 508 R packages has been downloaded from the CRAN repository of R and has been measured, using the SourceMonitor metrics tool. The resulted measurements, along with a significant number of specific attributes of the R packages, were examined and analyzed, leading to interesting conclusions such as the validity of a power law distribution regarding the majority of the sample's metrics and the absence of specific patterns due to the interdependencies among packages.

In addition we suggest that new developers prior to cooperate with high betweenness centrality or degree centrality and then closeness centrality, discuss that centrality measures can use to guide the preferential collaboration of OSS community.",10.1109/CGC.2012.50

Previous studies required coding systems that were time-consuming, expensive, and error-prone. Existing software can be expensive and inflexible, and furthermore, no single package allows for pre-parsing, sequential coding, and assignment of global ratings. We developed a free, open-source, and adaptable program to meet these needs: The CASAA Application for Coding Treatment Interactions (CACTI). Without transcripts, CACTI facilitates the real-time sequential coding of behavioral interactions using WAV-format audio files. Most elements of the interface are user-modifiable through a simple XML file, and can be further adapted using Java through the terms of the GNU Public License. Coding with this software yields interrater reliabilities comparable to previous methods, but at greatly reduced time and expense. CACTI is a flexible research tool that can simplify psychotherapy process research, and has the potential to contribute to the improvement of treatment content and delivery.",10.1371/journal.pone.0039740

In order to assist designers, many effective tools have been developed to support collaborative engineering, whose implementation is perceived as complex. Nowadays, industrial scenarios encourage companies to adopt PLM solutions, even if, sometimes, they can't understand the benefits. On the other hand, many free solutions with comparable functionalities are developed, which have been increasingly successful. In this article, we test different associations of software to make a comparison between free software and market solutions. In this experiment, 24 students in a Master's Degree course aimed to design mechanical products by using software to assist collaborative distributed design, using two different configurations. This experiment allowed us to compare design functionalities between free and commercial solutions, in order to determine ways to improve efficiency in a collaborative distributed design situation.

It shows revenue generation factor, cost efficiency factor and growth factor to have a positive influence on the OSS of Indian MFIs. Adjusted impairment loan loss allowance ratio, a portfolio risk factor and average loan size per borrower, a development factor, are seen to have a negative influence on OSS of Indian MFIs. The results thus infer five significant factors that Indian MFI managers must concentrate on to enhance the OSS of their organizations. The authors then discuss how mismanaging these five factors can deviate an MFI from its social goal of poverty alleviation. The crisis in Indian microfinance industry is explored to unveil the dangers involved in mismanagement of these factors.

Our results show that successful FLOSS teams demonstrate a truly global distribution of members, who perform different types of work so as to achieve consistent round-the-clock development, without any apparent ill effects on team productivity and the quality of the resulting outcomes. Cooperation between team members is abundant, especially at more complex work items, and does not seem to be affected by distance; only mentoring relationships appear in some cases to be easier to cultivate between individuals living closer together. These findings challenge the conventional wisdom of research in distributed work, in cases where virtual teams consist of highly skilled and motivated individuals, who leverage the power of communication technologies to overcome problems associated with physical distance.",NA

However, few studies have focused on the start-ups that enter the market just to exploit the new business opportunities stemming from the freely available technological knowledge developed by the FLOSS community (FLOSS-based start-ups). This paper aims to fill this gap by providing descriptive evidence about these firms. We address two main research questions: 1) What are the main features of FLOSS-based start-ups?; 2) What is their innovation process? We show that FLOSS-based start-ups follow a typical open innovation model that enables them to serve market niches that large incumbents are not structurally able to cover, profiting from the local production, distribution, and use of technological knowledge.

+1539,Article,Dynamic Models of Affiliation and the Network Structure of Problem Solving in an Open Source Software Project,"Two-mode networks are used to describe dual patterns of association between distinct social entities through their joint involvement in categories, activities, issues, and events. In empirical organizational research, the analysis of two-mode networks is typically accomplished either by (a) decomposition of the dual structure into its two unimodal components defined in terms of indirect relations between entities of the same kind or (b) direct statistical analysis of individual two-mode dyads. Both strategies are useful, but neither is fully satisfactory. In this article, the authors introduce newly developed stochastic actor-based models for two-mode networks that may be adopted to redress the limitations of current analytical strategies. The authors specify and estimate the model in the context of data they have collected on the dual association between software developers and software problems observed during a complete release cycle of an open source software project.

This study explored various factors that may enable OSS adoption within Australian Public Sector (APS) organisations by interviewing those involved in software procurement. The findings were analysed through the lens of administrative complexity associated with OSS adoption. Success of OSS in government agencies was found to be contingent on critical aspects such as availability of support and maintainability of OSS products, ability to meet organisational business needs in a cost effective manner, economic value associated with OSS such as maintenance and training costs, and attitude of staff toward OSS.

Static analysis methods are applied to each system to determine the number of for-loops and free-loops (i.e., loops that can be parallized). For each non-free loop the various inhibitors (to parallelization) are determined and counted. The results show that function calls within for-loops represent the vast majority of inhibitors and thus pose the greatest roadblock to adapt and re-engineer systems to better utilize parallelization. This is somewhat contradictory to the literature, which is focused primarily on the removal of data dependencies within loops. Additionally, the historical data of inhibitor counts for the set of systems is presented over a ten-year period.

For over a decade, the digital communities around the globe have used FOSS packages not only as an inexpensive way to access to information available on Internet, but also to disseminate thoughts, opinions and concerns about various socio-political and economic matters. Proxy servers and FOSS played a vital role in helping citizens in repressed countries to bypass the state imposed Internet content filtering and censorship practices. On the one hand, proxy servers act as redirectors to websites, and on the other hand, many of these servers are the main source for downloading FOSS anti-filtering software packages. These packages can provide secure web surfing via anonymous web access, data encryption. IP address masking, location concealment, browser history and cookie clean-ups but they also provide proxy software updates as well as domain name updates. The main objectives of this study are to investigate the role of FOSS packages in combating Internet content filtering and censorship and empowering citizens to effectively participate in communication discourse. By evaluating some of the well known FOSS anti-filtering packages used by Iran's digital community, this study found that despite the success of FOSS in combating filtering and state censorship, the majority of these software packages were not designed to meet the needs of Internet users. In particular, they are poorly adapted to the slow Internet connections in many developing countries such as Iran. In addition, these software packages do not meet the level of sophistication used by authorities to filter the content of the Net. Therefore, this study offers a new model that takes into account not only the existing level of the Internet infrastructure but also the growing number of Internet users demanding more effective FOSS packages for faster access to uncensored information while maintaining anonymity.

Artificial neural network analysis is used to analyse the content of the bylaws of six open source foundations ( Apache, Eclipse, GNOME, Plone, Python, and SPI) for the purpose of identifying power structures. Results of the research suggest that: i) the actions of an open source software foundation are centered around one of three groups: Members, Chairman/President/Executive Director, and Board of Directors; ii) in only one of the six foundations is the Board of Directors responsible for both the community and the product; and iii) artificial neural network analysis of the content of bylaws provides unbiased insights of the power structure of open source software foundations. These results may prove useful to those who contribute to open source foundations and use their products and services.",NA

The author theorizes Free Software as a new form of property that is infecting capitalism like a virus, challenging the system of private property central to its dominant logic. Free Software can be produced by developers working for free in peer communities or in profit-oriented firms. The author explores the conditions under which Free Software is produced through peer versus market-based production, emphasizing the implications for constructing the Free Software market and the digital commons. The author identifies actors' motivations, the organizational structure of production, and financial resources as three factors shaping these conditions. The author focuses on the case of Ubuntu, a Free Software operating system that is available free of charge on the Internet. Ubuntu is produced by Canonical, a Free Software, market-based firm, through an intriguing combination of market-based and peer production that both embodies and transforms capitalist practices.",10.1080/1369118X.2012.665938

Originally target based, cellular assays provide a way to test compounds (or other biological material such as small interfering RNA) in a more physiologically realistic in vitro environment. High-content screening (HCS) platforms are now available at lower cost, giving the opportunity for universities or research institutes to access those technologies for research purposes. However, the amount of information extracted from each experiment is multiplexed and hence difficult to handle. In such context, there is an important need for an easy-to-use, but still powerful software able to manage multidimensional screening data by performing adapted quality control and classification.

Recent examples appear to lend support to this, but there exist many detractors of OSS and resistance to the transformation it creates. Thus, it is relevant to take a closer look at the institutionalization of OSS. This paper evaluates the extent of OSS institutionalization in organizations. A practice or innovation is said to be institutionalized when it is taken-for-granted and its use becomes the norm. Drawing on institutional theory, the underlying concept of organizing vision and the rhetorical theory of diffusion of innovations, the authors analyze OSS institutionalization through the observation of the evolution of the public discourse about OSS and, simultaneously, the observation of the rate of adoption or diffusion of OSS in organizations.",10.1016/j.infsof.2012.07.001
+1576,Article,How Peripheral Developers Contribute to Open-Source Software Development,"Open-source software development is the next stage in the evolution of product development, particularly software products. Compared with the prevailing proprietary approaches, open-source software products are developed by co-opting external developers and prospective users. Although a core group of developers might still play a key role in the initial design and development, a notable aspect of the open-source software paradigm is the role of peripheral developers in the enhancement and popularization of the product. Peripheral developers are not formal members of the core development team. They voluntarily contribute their time and creative talent in improving the quality of the product or in popularizing the product through word-of-mouth advocacy. As volunteers, they are not subject to the traditional hierarchical controls, nor are they contractually obligated. Peripheral developers represent a novel and unique aspect of open-source software development, and there is a greater interest in tapping their potential. However, there has been limited evidence about how and when their participation has beneficial impacts. We examine how peripheral developers contribute to product quality and diffusion by utilizing longitudinal data on 147 open-source software products. Hierarchical linear modeling analysis indicates that peripheral developers make significant contributions to product quality and diffusion, especially on projects that are in the more mature stages of product development.",10.1287/isre.1100.0311

Although open source software (OSS) is not a new idea, several product development companies that operate in a market-driven context have started to use open source solutions as core software components in their products. Adopting open source core components implies a lower degree of control over software development and increased business risk associated with integrating differentiating contributions into the core release stream. Whether and how to adjust the current requirements management practices after the adoption of OSS components to fully benefit from the concept of open innovation has not yet been empirically explored. We outline experiences and challenges related to leveraging open innovation via engaging in OSS identified during 19 interviews with practitioners occupying different roles in the requirements management process at a large company followed by four validation interviews with other practitioners. We then propose a research agenda for requirements and decision management in the open innovation context and suggest which challenges in requirements engineering open innovation affects.",NA

Such systems have technical features that allow contributors to work in new ways, as various different workflows are possible. We plan to study this migration process to assess how developers' organization and their contributions are affected.

This approach is used to examine how F/OSS may contribute to a people-centred and development-oriented information society. Three questions are asked: (1) Is it helpful to view F/OSS as market or non-market production? (2) How is F/OSS distributed and marketed? (3) How does F/OSS rely on gendered labour? By analysing existing writings on F/OSS, it is concluded that market production should not be privileged over other modes of production; state intervention is required to ensure an equitable distribution of F/OSS; and gendered labour needs to be made visible in the F/OSS production.

Yet many unanswered questions exist regarding why certain FOSS projects succeed while others fail. Drawing on social capital theory and human agency theory, this study proposes that FOSS projects stand a better chance of success if they possess desirable social network capital and adopt effective strategies. It further argues that valuable social network capital and effective strategies produce greater returns together than they do alone. The results of an empirical analysis reveal significant positive interactions between social capital variables and human agency/strategy variables, highlighting the importance of complementarity between social network ties and strategies in shaping the outcome of FOSS projects.

Though the IMA architecture is mainly discussed from the view point of large aircrafts or manned aerial vehicles, small Unmanned Aerial Vehicles (UAV) are one that indeed requires IMA to reduce SWaP. In this study, we design and implement UAV control and mission software over ARINC 653. Especially we utilize our Linux-based ARINC-653, which can provide abundant development tools, software libraries, and device drivers due to the nature of Linux. Our control and mission software include Operational Flight Program (OFP), Video Streaming Program (VSP), Ground Control Program (GCP), and Ground Monitoring Program (GMP).

In fact, geographic information has unique intrinsic features, which makes it a natural indexing mechanism for spatial data. Due to its high cost and upgrade dynamics, this information should be available for reuse and should be managed and maintained by those responsible for producing it as part of management interventions in the territory. Therefore, it is important that different spatial data infrastructures, developed at different hierarchical levels, coexist and communicate in an interoperable way so that they can constitute a spatial basis of reference that facilitates the integration with other sectorial applications.

Many routine measurements require sequential processing of certain tasks, for instance to adjust the temperature of a sample stage, take a measurement, and repeat that cycle for other temperatures. This paper introduces an open-source Java program that processes a series of text-based commands that define the measurement sequence. These commands are in an intuitive format which provides great flexibility and allows quick and easy adaptation to various measurement needs. For each of these commands, the iC-framework calls a corresponding Java method that addresses the specified instrument to perform the desired task. The functionality of iC can be extended with minimal programming effort in Java or Python, and new measurement equipment can be addressed by defining new commands in a text file without any programming.",10.6028/jres.117.010

Designing maintenance-centric SE projects, however, is difficult because software code upon which these projects must be based is not readily available. Open Source Software (OSS) can alleviate this issue by offering a rich and varied volume of code. This rich diversity of OSS projects, however, presents the greatest hurdle in seamlessly selecting suitable projects for integration. To better understand the scope of this diversity, initially, we propose to manually select uniformly difficult projects of appropriate complexity. Ultimately, based on the experiences and insights acquired through the manual selection, we envision the development of a systematic methodology based on software metrics to ease the project selection process. Such a systematic methodology will pave the way for the adoption of the OSS-based approach at peer institutions, bringing us a step closer to injecting realism into SE projects.",NA

The results of this study suggest that it is beneficial to introduce usability activities into OSS development through the participative approach. In the participative approach the usability experts become recognized part of the development community through adapting their ways of work into the culture of the OSS project and submitting code patches. This participative approach had a clear impact in the case project as seen in changes in the user interface and in improved usability. The challenge of adapting usability and OSS development philosophies and practices should, however, be researched further.",10.1145/2399016.2399120

The study was conducted in two phases. The first phase focused on developing a learning management system using open source software - Moodle. This phase emphasized on the processes involved in designing and developing the learning management system prototype called E-Headship. The second phase evaluated participants' suitability in becoming future school leaders and managers through the use of E-Headship for the National Professional Qualification for Headship (NPQH) programme. E-Headship was then evaluated in terms of the applications of the learning management system. Sixty (60) participants from Institut Aminudin Baki (IAB) - an institute for training school administrators took part in the study.

Because students are accustomed to gathering information using commercial search engines, they can overlook high-quality library resources. To connect with student researchers when they need library resources, many libraries have built online research guides tied to specific subjects and courses. These guides can address specific assignments where research is required, and course instructors can point students to the guides to assist them in completing their research assignments successfully. In 2006, Oregon State University (OSU) Libraries developed an open source software product called Library a la Carte that librarians can use to construct research guides easily and quickly. The code was made available to other libraries, and a number of institutions have adopted the tool. A successful user community has grown up around Library a la Carte, but development up to this point has been the sole responsibility of OSU Libraries. We are now embarking on building a robust developer community, to contribute code, to build additional features and to take Library a la Carte into the future. As part of our plan to move forward, we are testing a hosted (cloud-based) version of the software. This paper introduces Library a la Carte, presents what was learned from the test and discusses moving forward with building a developer community. In addition, we touch on the benefits and challenges of building and sustaining an open source product from the ground up.",NA
+1594,InProceedings,Labeled topic detection of open source software from mining mass textual project profiles,"Nowadays open source software has become an indispensable basis for both individual and industrial software engineering. Various kinds of labeling mechanisms like categories, keywords and tags are used in open source communities to annotate projects and facilitate the discovery of certain software. However, as large amounts of software are attached with no/few labels or the existing labels are from different ontology space, it is still hard to retrieve potentially topic-relevant software. This paper highlights the valuable semantic information of project descriptions and labels, proposes labeled software topic detection (LSTD), a hybrid approach combining topic models and ranking mechanisms to detect and enrich the topics of software by mining the large amount of textual software profiles, which can be employed to do software categorization and tag recommendation. L-STD makes use of labeled LDA to capture the semantic correlations between labels and descriptions and then construct the label-based topic-word matrix. Based on the generated matrix and the generality of labels, LSTD designs a simple yet efficient algorithm to detect the latent topics of software that expressed as relevant and popular labels. Comprehensive evaluations are conducted on the large-scale datasets of representative open source communities and the results validate the effectiveness of LSTD.",10.1145/2384416.2384419

Using path-goal theory and built on leadership and motivation theories, we proposed and tested a model that can be used to assess the relationship between an OSS project leader's leadership style and a developer's motivation to contribute to the software development. We specifically decomposed the leadership and motivation construct to understand the hidden mechanisms by which leadership impacts motivation. A set of survey data collected from 118 OSS developers on Sourceforge.net was used to test our hypotheses. Our results indicate that leaders' transformational leadership is positively related to developers' intrinsic motivation and that leaders' active management style is positively related to the developers' extrinsic motivation.

The governing equations underlying MASCARET are the shallow water equations for unsteady flow propagation and the advection-dispersion equation for water quality and contaminant transport. The hydraulic component accounts for floodplains and storage areas, and flow at channel junction can be treated using a 2-D approach. Additionally, flood propagation over dry beds (e. g. dam-break flows) and non-hydrostatic waves can be simulated. The user interface FUDAA-MASCARET manages the input data, allocation of parameters, running of simulations and viewing outputs. MASCARET can be easily compiled as a dynamic library, offering special interfaces to be used with three main steps: Initialization, Run and Finalization of the calculation. With these features, MASCARET can be coupled or integrated to other softwares without requiring significant efforts. Since July 2011, MASCARET is worldwide distributed as an open-source code.

Our methods are based on complex network and time-series analysis. We define the notion of a working rhythm as the average time spent on a commit task and we study the correlation between working rhythm and communication frequency. We build communication networks for code developers, and find that the developers with higher social status, represented by the nodes with larger number of outgoing or incoming links, always have faster working rhythms and thus contribute more per unit time to the projects. We also study the dependency between work (committing) and talk (communication) activities, in particular the effect of their interleaving. We introduce multi-activity time-series and quantitative measures based on activity latencies to evaluate this dependency. Comparison of simulated time-series with the real ones suggests that when work and talk activities are in proximity they may accelerate each other in OSS systems. These findings suggest that frequent communication before and after committing activities is essential for effective software development in distributed systems.",10.1109/SocialInformatics.2012.17

Several discoveries were made by Voyager 2, including the Great Dark Spot (which has now disappeared) and Triton's geysers. Voyager 2 revealed the dynamics of Neptune's atmosphere and found four rings and evidence of ring arcs above Neptune. Benefiting from a greatly improved instrumentation, a mission as OSS would result in a striking advance in the study of the farthest planet of the solar system. Furthermore, OSS would provide a unique opportunity to visit a selected Kuiper Belt object subsequent to the passage of the Neptunian system. OSS would help consolidate the hypothesis of the origin of Triton as a Kuiper Belt object captured by Neptune, and to improve our knowledge on the formation of the solar system. The OSS probe would carry instruments allowing precise tracking of the spacecraft during the cruise. It would facilitate the best possible tests of the laws of gravity in deep space. These objectives are important for fundamental physics, as they test General Relativity, our current theoretical description of gravitation, but also for cosmology, astrophysics and planetary science, as General Relativity is used as a tool in all these domains. In particular, the models of solar system formation uses General Relativity to describe the crucial role of gravity. OSS is proposed as an international cooperation between ESA and NASA, giving the capability for ESA to launch an M-class mission towards the farthest planet of the solar system, and to a Kuiper Belt object. The proposed mission profile would allow to deliver a 500 kg class spacecraft. The design of the probe is mainly constrained by the deep space gravity test in order to minimize the perturbation of the accelerometer measurement.",10.1007/s10686-012-9309-y

It is, therefore, important to monitor how their quality evolves so that quality assurance activities can be properly planned. In this paper, we analyze empirically the quality evolution of an open source software system (Apache Tomcat). We address software quality from an external perspective. We used the number of defects as a quality indicator. We wanted to investigate if the Qi (Quality Assurance Indicator) metric, which we proposed in a previous work, can be used to observe how quality, measured in terms of defects, evolves in the presence of changes. We performed an empirical analysis using historical data collected from the subject system covering a period of more than seven years (thirty-one versions). Results are reported and discussed in the paper.",NA
+1620,InProceedings,On the Adoption of Open Source Software in Aeronautics,"Open source software has become an alternative to commercial software for industrial users. Industrial users adopting to OSS and the underlying concepts need to consider changing their software development practices and organization in order to benefit from the OSS model. These changes may involve both technical and non-technical aspects. Openness and collaboration with a community are two non-technical concepts that may require such changes, while evaluating OSS products or evaluating different strategies for integrating OSS products are two technical aspects that may require adoption. The objective of this paper is to create an awareness for the adoption of OSS in an industrial context. OSS can be used in different ways. Four categories of using OSS are presented by discussing motivation, implication and experience for each category. The main conclusion from this work is that organizations should have a realistic expectation of both the designated benefits and extension of organizational changes necessary to adopt to OSS. This conclusion is based on observations from industrial organizations using OSS, including OSS in the aeronautics industry, as well as from observations reported in the literature on open source.",NA

Developing these resources can be expensive and time consuming. Even when data and tools are intended for public re-use they often come with technical, legal, economic and social barriers that make them difficult to adopt, adapt and combine for use in new contexts. We focus on the promise of open, publically accessible software and data as well as crowdsourcing techniques to develop robust energy analysis tools that can deliver crucial, policy-relevant insight, particularly in developing countries, where planning resources are highly constrained-and the need to adapt these resources and methods to the local context is high. We survey existing research, which argues that these techniques can produce high-quality results, and also explore the potential role that linked, open data can play in both supporting the modelling process and in enhancing public engagement with energy issues.

One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model. We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using Cot its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.

These attributes make OSS an enticing technological choice for a company. Unfortunately, because most enterprises view technology as a proprietary differentiating element of their operation, little is known about the extent of OSS adoption in industry and the key drivers behind adoption decisions. In this article we examine factors and behaviors associated with the adoption of OSS and provide empirical findings through data gathered from the US Fortune-1000 companies. The data come from each company's web browsing and serving activities, gathered by sifting through more than 278 million web server log records and analyzing the results of thousands of network probes. We show that the adoption of OSS in large US companies is significant and is increasing over time through a low-churn transition, advancing from applications to platforms. Its adoption is a pragmatic decision influenced by network effects. It is likelier in larger organizations and those with many less productive employees, and is associated with IT and knowledge-intensive work and operating efficiencies. (C) 2011 Elsevier Inc.

+1638,Article,Reactive transport in aquatic ecosystems: Rapid model prototyping in the open source software R,"The concentrations of many natural compounds are altered by chemical and biological transformations, and physical processes such as adsorption and transport. Their fate can be predicted using reactive transport models that describe reaction and advective and dispersive movement of these components in their natural environment. Recently a number of software packages have been implemented in the open source software R that allow one to implement reactive transport models. Central to this is the ReacTran R-package, a comprehensive collection of functions for modeling reactive components that may be distributed over multiple phases, whose dynamics are coupled through biological and geochemical reactions, and that are transported in one-, two- or three-dimensional domains with simple geometries. Dedicated solution methods are in R-packages deSolve and rootSolve. The modeling packages facilitate the simulation of reaction and transport of components for spatial scales ranging from micrometers to kilometers and spanning multiple time-scales. As they are influenced in similar ways, the same functions can solve biogeochemical models of the sediment, groundwater, rivers, estuaries, lakes or water columns, experimental setups, or even describe reaction and transport within flat, cylindrical or spherical bodies, such as organisms, aggregates, or the dispersion of individuals on flat surfaces and so on. We illustrate the use of R for reactive transport modeling by three applications spanning several orders of magnitude with respect to spatial and temporal scales. They comprise (1) a model of an experimental flow-through sediment reactor, where fitting so-called breakthrough curves are used to derive sulfate reduction rates in an estuarine sediment, (2) a conservative and reactive tracer addition experiment in a small stream, which implements the concept of river spiraling, and (3) a 2-D and 3-D model that describes oxygen dynamics in the upper layers of the sediment, interspersed with several hotspots of increased reaction intensities. The packages ReacTran, deSolve and rootSolve are implemented in the software R and thus available for all popular platforms (Linux, Windows, Mac). Models implemented using this software are short and easily readable, yet they are efficiently solved. This makes R extremely well suited for rapid model prototyping. (C) 2011 Elsevier Ltd.

Because of the difficulty of collecting and standardizing data, most existing work could only utilize small project set. In this study, we target the open source software universe to build a universal code evolution model for large-scale data. We consider code evolution from two aspects: code version changing history in a single project and code reuse history in the whole universe. In the model, files/modules are built as nodes, and relations (version change or reuse) between files/modules are built as connections. Based on the model, we design and implement a code evolution review framework, i.e., Code Evolution Reviewer (CER), which provides a series of data interfaces to review code evolution history, in particular, code version changing in single project and code reuse among projects.

The authors suggest that the new paradigm of open innovation may impact a firm's adaptability and responsiveness under conditions of environmental flux. However, extending innovation capacity by opening the innovation process poses major challenges for firms. The aims of this study are to explore the characteristics of open innovation activity and to contemplate the role of strategic flexibility in the design of business models based upon open innovation. Design/methodology/approach - The study draws upon a qualitative research approach through a longitudinal case study in the field of open source software (OSS). The empirical case illustrates how an OSS firm utilizes signals in its environment to flexibly alter its business model. Findings - A business model that embodies open innovation raises dilemmas between open and closed innovation paradigms. However, the authors' case highlights that an ambidextrous approach that combines market orientation with the principles of open innovation increases profitability, shortens time to market through effective market access, and enhances innovation capability. Research limitations/implications - The results have profound implications for industrial marketers, managers, management consultants and business educators. They can use the insights gleaned from this research to guide the development of business models that involve open innovation. The results indicate that firms involved in open innovation need reactive strategic flexibility to cope with the environmental diversity and variability. However, this study analyzes a single case in the field of OSS and one should be cautious when generalizing the findings. Originality/value - This paper improves the understanding of the relationship between flexibility and market orientation. It combines two areas that have previously been discussed separately, i.e. market orientation and open innovation.",10.1108/03090561211248071

It distinguishes FOSS projects that are still at the initial stage of development from those at the growth stage, and posits that the relative importance of the identified survival factors changes as FOSS projects evolve from one stage to the next. The results demonstrate the changing effect of factors over time affecting FOSS survival. Restrictive FOSS licenses and large internal and external networks are found to present advantages for projects that are at the initial stage, but the advantages dissipate as the projects move into the growth stage. Projects with high-quality external networks, greater levels of user/developer participation and service quality, and projects targeted at technical users have a higher likelihood of surviving at both stages. These findings show that a FOSS project team needs to be aware of the conditioning effect of time and focus on the appropriate mix of survival factors as the project moves from one stage to the next.

The excessive increase in motorization indexes in developed countries produces irreversible damage to the environment and impairs citizens' quality of life. Urban public transport can help to improve people's wellbeing and achieve sustainable development in cities. Operations support systems (OSS) are integral control systems that, when applied to transportation networks, can provide the required means to identify, regulate and manage the available resources in real time. The main objective of this study was to examine the current relationship between investment in OSS and improvement in the quality of service in businesses providing urban transport services in local settings in Spain.

Although researchers have studied some predictors of OSS project performance, there is a lack of empirical work that studies the impact of project capabilities on the performance of OSS projects. Therefore, this paper studies project capabilities as potential predictors of OSS project performance. The data, gathered from 607 OSS projects over time (in two snap-shots), were consistent with Dynamic Capability Theory (DCT). In other words, the results showed that in order to achieve higher project performance, OSS projects need to have strong capabilities in terms of proactive and efficient defect-removal as well as proactive and efficient functionality-enhancement. The implications of these results for the OSS research community are discussed, followed by recommendations for OSS practitioners. (C) 2011 Elsevier Ltd. APM and IPMA.

Due to a lack of sustained contributors, however, most FLOSS projects do not survive. The early identification of developers who are likely to remain is thus an eminent challenge for the management of FLOSS initiatives. Previous research has shown that individuals' subjective assessment is often inaccurate emphasizing the need to objectively evaluate retention behavior. Consistent with the concepts Person-Job (P-J) and Person-Team (P-T) fit from the traditional recruitment literature, we derive objective measures to predict developer retention in FLOSS projects. In an analysis of the contribution behavior of former Google Summer of Code (GSoC) students we reveal that the level of development experience and conversational knowledge is strongly associated with retention. Surprisingly, our analysis reveals that students with abilities that are underrepresented in the project and students with a higher academic education do not remain considerably longer.",10.1109/HICSS.2012.644

However, while there is no shortage on research on individuals' motivation for contributing to open source, few have investigated the commercial companies' motivations for doing the same. A case study was conducted at three different companies from the IT service industry, to investigate three possible drivers: sale of complimentary services, innovation and opensourcing (outsourcing). We offer three conclusions. First, we identified three main drivers for contributing to open source, which are (a) selling complimentary services, (b) building greater innovative capability and (c) cost reduction through opensourcing to an external community. Second, while previous research has documented that the most important driver is selling complimentary services, we found that this picture is too simple. Our evidence points to a broader set of motivations, in the sense that all our cases exhibit combinations of the three drivers. Finally, our findings suggest that there might be a shift in how commercial companies view open source software. The companies interviewed have all expressed a moral obligation to contribute to open source. (C) 2011 Elsevier Ltd. All rights reserved.",10.1016/j.ijinfomgt.2011.10.003

Some developers are unpaid volunteers who seek to solve their own technical problems, while others create OSS as part of their employment contract. For the past 10 years, a substantial amount of academic work has theorized about and empirically examined developer motivations. We review this work and suggest considering motivation in terms of the values of the social practice in which developers participate. Based on the social philosophy of Alasdair MacIntyre, we construct a theoretical framework that expands our assumptions about individual motivation to include the idea of a long-term, value-informed quest beyond short-term rewards. This motivation-practice framework depicts how the social practice and its supporting institutions mediate between individual motivation and outcome. The framework contains three theoretical conjectures that seek to explain how collectively elaborated standards of excellence prompt developers to produce high-quality software, change institutions, and sustain OSS development. From the framework, we derive six concrete propositions and suggest a new research agenda on motivation in OSS. [PUBLICATION ABSTRACT]",NA

One way federal procurement regulations advance public interest is by seeking ""optimal"" or ""best"" value in purchasing decisions. For each purchasing option, one determines the net benefit, which is a discounted difference between all present and future costs and benefits. This study considers the implications of pricing thresholds on government procurement processes in light of the advent and increasing use of free enterprise software. Researchers conducted a randomized Web-based survey of 138 government procurement officials (IT managers). The results indicate that free software may provide procurement officials with an opportunity to bypass institutionalized procurement best practices.

In doing so, we consider the content of potential information flows within the network and argue that the impact of network structure on technology adoption can be better understood by separately examining its impact from two groups of alters-current and potential adopters. We contend that increased network centrality and closure among current adopters contribute positively to adoption, whereas the same among potential adopters has exactly the opposite impact. Accordingly, we propose a dynamic view where the fraction of current adopters in the network positively moderates the impact of network centrality and closure. We empirically test the theory by analyzing the adoption of software version control technology by open source software projects. Our results strongly support the theory.",10.1287/isre.2013.0494

The challenge facing most organizations is how to evaluate OSS adoption benefits. OSS adoption is a complex phenomenon which requires an interdisciplinary approach to understand the socio-technical, political, economic and legal benefits. The complexity of the OSS phenomenon has resulted in fiercely contested, contradictory rhetorical discussions among divided parties with no conclusive general agreement. The one size fits all approach is fundamentally flawed for evaluating OSS benefits in organizations as they are both subjective and contextual. In this paper we propose a framework to balance the needs of hard (objective) benefits and soft (subjective) benefits of OSS adoption in public sector organizations. This paper proposes a framework to evaluate benefits of OSS adoption in public-sector organizations, since one-size-fits-all approaches have shortcomings to complex phenomena.",NA

Currently, OSS is widely used in many aspects of IT society. Because OSS development is community based, unlike commercial software, the lack of good documentation or the maintenance of manuals is one of the main problems of using OSS. Due to its rapid development, OSS manuals become easily obsolete. Moreover, the installation or the usage varies depending on the operating system. To solve the documentation problems, Murakami et al. proposed a method of automatically generating a web manual for installing an OSS by editing the log information recorded during the installation process. Unfortunately, the web manual generated by this system was not suitable for wide use in learning management systems. Therefore, this paper extends the system by Murakami et al. to one with the ability to deliver an automatically generated Web manual on an e-learning management system, modify the content of the manual, and skip unnecessary information in the learning process.

We illustrate our results with examples concerning to very damaged churches and a urban district of Segovia (World Cultural Heritage). Their connection with appropriate database eases the building evolution and interventions tracking. We have incorporated some preliminary examples to illustrate Advanced Visualization Tools and architectural e-Learning software platform which have been created for assessing conservation and restoration tasks in very damaged buildings. First version of the Advanced Visualization application has been developed in the framework of ADISPA Spanish Project Results. Our results are illustrated with the application of these software applications to several very damaged cultural heritage buildings in rural zones of Castilla y Leon (Spain).",NA
+1715,Article,AUREA: an open-source software system for accurate and user-friendly identification of relative expression molecular signatures,"Background: Public databases such as the NCBI Gene Expression Omnibus contain extensive and exponentially increasing amounts of high-throughput data that can be applied to molecular phenotype characterization. Collectively, these data can be analyzed for such purposes as disease diagnosis or phenotype classification. One family of algorithms that has proven useful for disease classification is based on relative expression analysis and includes the Top-Scoring Pair (TSP), k-Top-Scoring Pairs (k-TSP), Top-Scoring Triplet (TST) and Differential Rank Conservation (DIRAC) algorithms. These relative expression analysis algorithms hold significant advantages for identifying interpretable molecular signatures for disease classification, and have been implemented previously on a variety of computational platforms with varying degrees of usability. To increase the user-base and maximize the utility of these methods, we developed the program AUREA (Adaptive Unified Relative Expression Analyzer)-a cross-platform tool that has a consistent application programming interface (API), an easy-to-use graphical user interface (GUI), fast running times and automated parameter discovery. Results: Herein, we describe AUREA, an efficient, cohesive, and user-friendly open-source software system that comprises a suite of methods for relative expression analysis. AUREA incorporates existing methods, while extending their capabilities and bringing uniformity to their interfaces. We demonstrate that combining these algorithms and adaptively tuning parameters on the training sets makes these algorithms more consistent in their performance and demonstrate the effectiveness of our adaptive parameter tuner by comparing accuracy across diverse datasets. Conclusions: We have integrated several relative expression analysis algorithms and provided a unified interface for their implementation while making data acquisition, parameter fixing, data merging, and results analysis `point- and -click' simple. The unified interface and the adaptive parameter tuning of AUREA provide an effective framework in which to investigate the massive amounts of publically available data by both `in silico' and `bench' scientists.

It also proposes a comprehensive model that integrates individual, social, and software characteristics to measure the acceptance of open source software. Based on the three-pronged approach, the study puts forward an integrated model consisting of the extended technology model, the innovation diffusion theory and software characteristics. A full-scale field survey of 1,005 open source software users was undertaken and both convergent and discriminant validities were conducted. The results of the structural equation modeling illustrate that perceived ease of use, perceived usefulness, intention to use, output quality, compatibility, software functionality, and software maintainability have a statistically positive relationship with open source software acceptance. Contrary to most studies, which did not find a positive relationship between visibility and trialability towards the acceptance of open source software, it is interesting to observe that this study did find a positive relationship. Conclusions and discussions of the findings, and their academic and practical implications are also presented.",10.1177/0266666912465880

The purpose of this study was to conduct an investigation of FOSS adoption in firms operating in high-velocity environments and identify factors that have an impact on the adoption process. Primary data were gathered from a cluster of firms operating in a high-velocity environment. The results provide an insight about the FOSS adoption process to both practitioners and academics alike. Our results indicate that performance attitude of managers, data regulation and facilitating conditions are important determinants of a firm's behavioural intention (BI) to adopt and use FOSS. Interestingly, influences from social and organisational domains have little effect on a firm's BI to adopt FOSS solutions.

For the healthcare sector, the use of OSS has been studied in the literature with contradicting findings. Regarding OSS in clinical applications, mainly case studies from hospital-wide IS have been reported. Agile methods have been examined merely in the context of healthcare software product development. However, the development of web-based applications in clinical departments using agile methods and OSS has not been studied so far. Thus, in this paper the feasibility of such an approach is examined for an electronic case report form (eCRF) application for orthopaedical studies. It is demonstrated how OSS-based web engineering projects may be successfully accomplished in highly specialized environments like clinical departments by properly taking into account their specific requirements.",10.1007/978-3-642-39200-9_37
+1719,Article,All Are Not Equal: An Examination of the Economic Returns to Different Forms of Participation in Open Source Software Communities,"Open source software (OSS) communities live and die with the continuous contributions of programmers who often participate without direct remuneration. An intriguing question is whether such sustained participation in OSS projects yields economic benefits to the participants. Moreover, as participants engage in OSS projects, they take on different roles and activities in the community. This raises additional questions of whether different forms of participation in OSS communities are associated with different economic rewards and, if so, in which contexts. In this paper, we draw upon theories of signaling and job matching to hypothesize that participants who possess ``proof{''} of their skills in OSS projects are financially rewarded for their activities in the labor market. More specifically, we distinguish between participation in OSS communities that is associated with a signaling value for unobserved productivity characteristics and an additional value that accrues to participants whose OSS roles and activities match those in their paid employment. Following a cohort of OSS programmers over a six-year period, we empirically examine the wages and OSS performance of participants in three of the foremost OSS projects operating within the Apache Software Foundation. Controlling for individual characteristics and other wage-related factors, our findings reveal that credentials earned through a merit-based ranking system are associated with as much as an 18\\% increase in wages. Moreover, we find that participants who have OSS project management responsibilities receive additional financial rewards if their professional job is in IT management. These findings suggest that rank within an OSS meritocracy is a credible and precise signal of participants' productive capacity and that participants' roles and activities in an OSS community have additional financial value when aligned with their paid employment.",10.1287/isre.2013.0474

OSS projects allow end users to directly submit reports in case of any operational issues. Timely resolution of these defect reports requires effective management of maintenance resources. This study analyzes the usefulness of the textual content of the defect reports as an early indicator of their resolution time. Text Mining techniques are used to categorize defect reports of five OSS projects. Significant variation in the defect resolution time amongst the resulting categories, for each of the sample projects, indicates that a text based classification of defect reports can be useful in early assessment of resolution time before source code level analysis. Such technique can assist in allocation of sufficient maintenance resources to targeted defects and also enable project teams to manage customer expectations regarding defect resolution times.",10.1007/s10664-012-9197-9

However, it has been criticized that FLOSS development is often considered as a homogeneous phenomenon grounded by assumptions rather than empirical evidence. Proper empirical methods that can shed light into FLOSS development are desirable. In this paper, we propose an empirical method to validate a software development model for FLOSS, the Adapted Staged Model for FLOSS. We mined some selected metrics from Apache Ivy and study their evolution using S-shaped curves. Our results indicate that S-shaped curves can model software evolution well for Ivy. Moreover, we demonstrated that our method can be used to identify successfully different stages of its development, validating part of the Adapted Staged Model for FLOSS.",10.1109/ICSM.2013.74

Unfortunately, the current state-of-the-art is poorly equipped to mine floss refactoring from version histories, mainly because they infer refactorings by comparing two snapshots of a system and making educated guesses about the precise edit operations applied in between. In this paper we propose a solution that reconstructs refactorings not on snapshots of a system but using the actual changes as they are performed in an integrated development environment. We compare our solution against RefFinder and demonstrate that on a small yet representative program (the well-known ``VideoRental system{''}) our approach is more accurate in identifying occurrences of the ``MOVEMETHOD{''} and ``RENAMEMETHOD{''} refactorings.",10.1109/ICSM.2013.53

+1730,InProceedings,An open source software approach to combine simulation and optimization of business processes,"Business processes of modern companies are characterized by a huge complexity which is caused for example by quickly changing markets, short product life cycles or dynamic interactions between particular subsystems of a company. Business process management is intended to implement efficient and customer orientated processes whereby the simulation of business processes can be used to evaluate the quality of processes and to identify areas of improvements. Since real business processes usually contain decision processes which can be solved by optimization systems, it makes sense to,combine the simulation and the optimization of business processes. (Marz et.al. 2010, p 3ff.) As an example of a reasonable combined simulation and optimization of business processes, the navigation in a road network is discussed in this paper. Consider vehicles seeking the fastest route from a starting node to a target node using a navigation system. The amount of time spent driving on an arc is influenced by the distance and the amount of the vehicles on this arc and is continuously changing. The structure of the road network and the traffic within the network is described in a simulation model while the fastest path decisions of each vehicle are made by using an optimization system. There is obviously a relationship between the individual decisions made for each of the vehicles and the state of the entire network. The aim of this paper is to describe how a combined simulation and optimization of business processes can be created through using EPC-Simulator (Muller 2012) as a simulation system and CMPL (Steglich and Schleiff 2010) as an optimization system where the network traffic simulation is used exemplarily.",10.7148/2013-0808

Our goal is to analyze the connectivity structure of the social networks of contributors and to investigate the effect of the different social tie structures on developers' overall productivity to OSS projects. We first analyze the general structure of the social networks, e.g., graph distances and the degree distribution of the social networks. Our analysis confirms that the social networks of OSS communities follow power-law degree distributions and exhibit small-world characteristics. However, the degree mixing pattern shows that high degree nodes tend to connect more with low degree nodes, suggesting collaborations between experts and newbie developers. Second, we study the correlation between graph degrees and the productivity of the contributors in terms of the amount of contribution and commitment to OSS projects. The analysis demonstrates evident influence of the social ties on the developers' overall productivity.",10.1145/2492517.2492627
+1736,Article,Antecedents of open source software adoption in health care organizations: A qualitative survey of experts in Canada,"Purpose: Open source software (OSS) adoption and use in health care organizations (HCOs) is relatively low in developed countries, but several contextual factors have recently encouraged the consideration of the possible role of OSS in information technology (IT) application portfolios. This article aims at developing a research model for investigating the antecedents of OSS adoption decisions in HCOs. Methods: Based on a conceptual framework derived from a synthesis of the literature on IT adoption in organizations, we conducted 18 semi-structured interviews with IT experts from all levels of the Province of Quebec's health and social services sector in Canada. We also interviewed 10 IT suppliers in the province. A qualitative data analysis of the interviews was performed to identify major antecedents of OSS adoption decisions in HCOs. Results: Eight factors associated with three distinct theoretical perspectives influence OSS adoption. More specifically, they are associated with the classical diffusion of innovations theory, the theory of resources, as well as institutional theory and its spin-off, the organizing vision theory. The factors fall under three categories: the characteristics of OSS as an innovation, the characteristics of the HCO with respect to its ability to absorb OSS, and the characteristics of the external environment with respect to institutional pressures and public discourse surrounding OSS. We shed light on two novel factors that closely interact with each other: (1) interest of the health care community in the public discourse surrounding OSS, and (2) clarity, consistency and richness of this discourse, whether found in magazines or other media. Conclusions: OSS still raises many questions and presents several challenges for HCOs. It is crucial that the different factors that explain an HCO's decision on OSS adoption be considered simultaneously. Doing so allows a better understanding of HCOs' rationale when deciding to adopt, or not to adopt, OSS. (C) 2013 Elsevier Ireland Ltd. All rights reserved.",10.1016/j.ijmedinf.2013.04.001

+1741,Article,Building 3D GIS data models using open source software,"Today, many GIS applications would require data sets containing full 3D data; application fields like urban and town planning, civil protection, cadastres and environmental studies could use full 3D data, both to carry out spatial analyses and inquiries as well as for only visualization. Data model can be accessed by desktop application as well as from Internet. This second option is becoming today the most requested. But in order to share 3D data model through Internet it is necessary to configure a suitable system. A 3D model can be shared on Internet in different ways. It is possible to incorporate a model inside an executable or 3D PDF file or build something like a multimedia application (i.e. flash based). However a better option is to put a model inside a geospatial database and build suitable web services to access it using Internet browsers. This second option can be performed using different solutions for web servers, development platforms and programming languages. Fundamental for this option is the construction of the model that should be structured, according a conceptual model to be replicable and interoperable. Hence, the model should be stored in a geospatial database in order to be accessed by an application running under a web server, so allowing access to the model. All this is the object of the research-Management and use of distributed 3D data by open source WebGIS software-that is part of the Italian PRIN 2007 research project: Interoperability and cooperative management of geographic, dynamic, multi-dimensional and distributed data with Free and Open Source GIS (Principal investigator Paolo Zatelli), aimed to build urban and suburban 3D models with CAD software or solid modellers, share them with a 3D Web Feature Service Open Geospatial Consortium web feature service like, and them using Internet browsers all done using only free and open source software. The research work, here illustrated, which was funded by previous research project, deals with the construction of a suitable model and the storage of the model inside a geospatial database. The work is based on the use of free and open source software; Blender and PostgreSQL with PostGIS have been used, respectively, to draw objects of the model and save their data with the help of some Python scripts; the server side part of the system has been realized using Tomcat with servlets and applets all written in Java.

Python scripts, activated by Blender, allow saving data into a spatial database implemented through PostgreSQL and PostGIS that could be a remote database somewhere on the net; all geometrical and topological information, implemented in the 3D model, is so transferred in PostGIS. This information can be retrieved by Blender using other Python scripts, so Blender fully interacts with 3D data allocated in PostGIS. These data can be also accessed by many other clients, both directly using a database client and using other protocols (like HTTP on Internet).

Triaging bugs can become a laborious task particularly in open source software (OSS) projects with a large base of comparably inexperienced part-time contributors. In this paper, we propose an efficient and practical method to identify valid bug reports which a) refer to an actual software bug, b) are not duplicates and c) contain enough information to be processed right away. Our classification is based on nine measures to quantify the social embeddedness of bug reporters in the collaboration network. We demonstrate its applicability in a case study, using a comprehensive data set of more than 7 0 0; 0 0 0 bug reports obtained from the BUGZILLA installation of four major OSS communities, for a period of more than ten years. For those projects that exhibit the lowest fraction of valid bug reports, we find that the bug reporters' position in the collaboration network is a strong indicator for the quality of bug reports. Based on this finding, we develop an automated classification scheme that can easily be integrated into bug tracking platforms and analyze its performance in the considered OSS communities. A support vector machine (SVM) to identify valid bug reports based on the nine measures yields a precision of up to 90.3\\% with an associated recall of 38.9\\%. With this, we significantly improve the results obtained in previous case studies for an automated early identification of bugs that are eventually fixed. Furthermore, our study highlights the potential of using quantitative measures of social organization in collaborative software engineering. It also opens a broad perspective for the integration of social awareness in the design of support infrastructures.",NA

Domain specific simulation and engineering tools partly address the challenges of complex system behavior. Different component technologies, customer behavior and controls in the power networks are interacting in a highly dynamic manner. Results of isolated simulations may be not accurate enough on the system level. Free and open available tools like GridLAB-D, PSAT, OpenModelica and 4DIAC are well known and widely used because of their excellent domain specific expertise. With co-simulation approaches the individual strengths of each tool can be exploited to model and simulate the various aspects of complex smart grids. The achieved level of detail and realism potentially surpasses the results that the individual analyses would gain. This paper demonstrates a local smart charging control strategy implemented with the IEC 61499-based standard for distributed control systems. It is simulated with different electric vehicle driving patterns, modeled with the multi-agent environment GridLAB-D.

All open source licenses grant the right to fork their code, that is to start a new development effort using an existing code as its base. Thus, code forking represents the single greatest tool available for guaranteeing sustainability in open source software. In addition to bolstering program sustainability, code forking directly affects the governance of open source initiatives. Forking, and even the mere possibility of forking code, affects the governance and sustainability of open source initiatives on three distinct levels: software, community, and ecosystem. On the software level, the right to fork makes planned obsolescence, versioning, vendor lockin, end-of-support issues, and similar initiatives all but impossible to implement. On the community level, forking impacts both sustainability and governance through the power it grants the community to safeguard against unfavourable actions by corporations or project leaders. On the business-ecosystem level forking can serve as a catalyst for innovation while simultaneously promoting better quality software through natural selection. Thus, forking helps keep open source initiatives relevant and presents opportunities for the development and commercialization of current and abandoned programs.",NA

This kind of streaming technology is mainly used with HTTP 1.0 and 1.1 respectively, which both have some drawbacks. Therefore, the IETF has started the development of HTTP 2.0, which is based on Google's SPDY proposal and already supported by several major companies, e. g., Facebook, Twitter, Akamai, Mozilla and obviously Google. Furthermore, Content Centric Networking (CCN) is another novel approach for future networks that is considered as an revolutionary approach compared to HTTP 2.0. The CCN communication paradigm is completely different and does not rely on direct connections between hosts, it rather focuses on the content.

The developed module simulates, partially, the dynamics of a real pilot plant belonging to the Industrial Process Laboratory of the Engineering College of the UFJF, incorporating some of its complexities and nonlinearities and operates with the same time constants. The developed HIL platform, totally FOSS-based, can reinforce the educational laboratory practices for improving engineering education especially that one related to industrial process control, supervision, and optimization.",10.1007/s40313-013-0013-6
+1758,Article,Development of a web GIS application for emissions inventory spatial allocation based on open source software tools,"Combining emission inventory methods and geographic information systems (GIS) remains a key issue for environmental modelling and management purposes. This paper examines the development of a web GIS application as part of an emission inventory system that produces maps and files with spatial allocated emissions in a grid format. The study is not confined in the maps produced but also presents the features and capabilities of a web application that can be used by every user even without any prior knowledge of the GIS field. The development of the application was based on open source software tools such as MapServer for the GIS functions, PostgreSQL and PostGIS for the data management and HTML, PHP and JavaScript as programming languages. In addition, background processes are used in an innovative manner to handle the time consuming and computational costly procedures of the application. Furthermore, a web map service was created to provide maps to other clients such as the Google Maps API v3 that is used as part of the user interface. The output of the application includes maps in vector and raster format, maps with temporal resolution on daily and hourly basis, grid files that can be used by air quality management systems and grid files consistent with the European Monitoring and Evaluation Programme Grid. Although the system was developed and validated for the Republic of Cyprus covering a remarkable wide range of pollutant and emissions sources, it can be easily customized for use in other countries or smaller areas, as long as geospatial and activity data are available.

Can social issues that emerge be identified and addressed before it is too late? Can the community heal itself, become more transparent and inclusive, and promote diversity? We propose a technique to address these issues by quantitative analysis of social dynamics in FOSS communities.

+1762,Article,Effort estimation of FLOSS projects: a study of the Linux kernel,"Empirical research on Free/Libre/Open Source Software (FLOSS) has shown that developers tend to cluster around two main roles: ``core{''} contributors differ from ``peripheral{''} developers in terms of a larger number of responsibilities and a higher productivity pattern. A further, cross-cutting characterization of developers could be achieved by associating developers with ``time slots{''}, and different patterns of activity and effort could be associated to such slots. Such analysis, if replicated, could be used not only to compare different FLOSS communities, and to evaluate their stability and maturity, but also to determine within projects, how the effort is distributed in a given period, and to estimate future needs with respect to key points in the software life-cycle (e.g., major releases). This study analyses the activity patterns within the Linux kernel project, at first focusing on the overall distribution of effort and activity within weeks and days; then, dividing each day into three 8-hour time slots, and focusing on effort and activity around major releases. Such analyses have the objective of evaluating effort, productivity and types of activity globally and around major releases. They enable a comparison of these releases and patterns of effort and activities with traditional software products and processes, and in turn, the identification of company-driven projects (i.e., working mainly during office hours) among FLOSS endeavors. The results of this research show that, overall, the effort within the Linux kernel community is constant (albeit at different levels) throughout the week, signalling the need of updated estimation models, different from those used in traditional 9am-5pm, Monday to Friday commercial companies. It also becomes evident that the activity before a release is vastly different from after a release, and that the changes show an increase in code complexity in specific time slots (notably in the late night hours), which will later require additional maintenance efforts.",10.1007/s10664-011-9191-7

In the curriculum of majority of engineering branches there are certain abstract concepts. The students find it difficult to understand these concepts. There are many methods which are being followed to make the students understand concepts. One such method is the use of CAD tools When computers came into class rooms, the need for CAD tools also arose {[}1]. They help the students to visualize many basic concepts which, they otherwise cannot see in the physical world. In this 21st century, dominated by social networking, the tools required to educate them have also come to be available in free of cost. Such tools are called open source software or FOSS tools. We have proposed a teaching methodology that involves the usage of open source software tools along with traditional teaching which enable the communication engineering students to understand complex concepts pertaining to the subject of Antenna and wave propagation. We carried out an experiment with forty students from fifth semester Electronics and Communication Engineering department. The students used a FOSS tool and gave a test based on designing of various antennas with desired radiation patterns by selecting different parameters before and after using the tool. The scores of the two tests show that there was an increase in the marks obtained by students in the test after using the tool. Thus the use of FOSS tool helped students perform better in the test. This may be because the tool has visualizations which help student understand the abstract concepts such as antenna radiation pattern and wave propagation.",10.1109/T4E.2013.32
+1765,InProceedings,Exploring Possibilities to Analyse Microblogs for Dependability Information in Variability-intensive Open Source Software Systems,"Many open source software systems are variability-intensive because they are frequently adapted to different customer needs or deployment environments. Variability in these systems not only occurs in functionality, but also in quality attributes (e. g., security, reliability, dependability). Furthermore, variability in functionality and variability in quality attributes affect each other. Recently, open source communities have adopted microblogging to document and share software engineering knowledge. Microblogging dissolves boundaries between developers and other stakeholders (e.g., end users). This facilitates the involvement of many different non-technical stakeholders in the software development process. In this paper, we investigate the feasibility and suitability of utilizing microblogs to identify and analyze dependability information about open source software systems. We use the example of the currently most popular microblogging infrastructure (Twitter) and a widely used open source content management system (Drupal). Our results indicate that even though open source communities frequently share information on Twitter, challenges exist for extracting and analyzing dependability information. Furthermore, a better understanding is needed to describe the relation between issues reported by user communities in microblogs, and issues and actions documented by developer communities in change logs and release information.",NA
+1766,InProceedings,Exploring Socio-Technical Dependencies in Open Source Software Projects,"Comprehension of Open Source Software (OSS) projects is traditionally driven by the plethora of data produced and maintained by these projects. The data, in one hand, encapsulates the tacit knowledge on the evolution of the software itself. And, on the other hand, provides the history of communication and collaboration of the community. Acquisition and analysis of such data has been mostly manual or semi-automated and error-prone, mainly due to unstructured and substandard data representation. This increases the validity threat of the reported results and makes it incomparable across the studies. With the advancement of data management tools and technologies, many third party data providers are putting serious effort to provide OSS project's data in a standard and platform independent format. In this paper, we propose a framework to fully automate the analysis and visualization of OSS evolution data through the use of existing data services. As a proof of concept we implemented a tool named POMAZ. We demonstrate the applicability of the tool in the context of two related open source projects FFmpeg and GStreamer.",10.1145/2523429.2523468

OSS requires firms to rethink the processes that facilitate value creation and capture. The objective of this paper is to theorise how firms create and capture value from OSS. We derive a model from extant research and refine it through the study of three inter-organisational networks. The findings reveal how a firm's ability to access a value network of complementors is crucial for effective value creation and capture. Two types of networks are evident: a high-density network of familiar partners and a low-density network of multiple, often unfamiliar, partners. Leveraging these networks depends on the level of commitment, volume of knowledge exchange and the alignment of objectives among participant firms. Effective governance is revealed as critical for creating and capturing value within both types of network; and depends on both formal and informal mechanisms.",10.1057/ejis.2012.44

Overland flooding, the most common type of flooding event usually occurs when rivers or streams overflow their banks as a result of heavy rainfalls or fast snowmelt. In European Union, flood defence management is an essential part of the integrated water management and the European Commission Directive 2007/60, regarding the estimation and management of the flood risks, states that all the member countries have to achieve flood risks maps till the end of 2013. Flood hazard maps must be created to help the communities in finding out which are the different flood risk areas and to provide public awareness and useful information to local authorities and decisions makers in case of possible flood events. Flood risk areas should be also identified and delimited for future land use and development. The development of risk maps assumes the existence and access to extensive databases, detailed maps and GIS data depots for most of the necessary information, as well as expensive software (i.e. ArcGIS, MIKE) and skilled experts. Unfortunately, these criteria are not always met. This paper presents an alternative method to prepare preliminary floodplain maps, based on the use of Autodesk products and Open Source software. The purpose of the method is to introduce basic satellite image display and processing techniques using open source software and freely available satellite data to allow floodplain maps development without using expensive software and unaffordable data. The method consists in DTM (Digital Terrain Model) generation, rivers and watershed delineation and hydraulic modelling in order to generate floodplain maps.",NA
+1771,Article,FRED (A Framework for Reconstructing Epidemic Dynamics): an open-source software system for modeling infectious diseases and control strategies using census-based populations,"Background: Mathematical and computational models provide valuable tools that help public health planners to evaluate competing health interventions, especially for novel circumstances that cannot be examined through observational or controlled studies, such as pandemic influenza. The spread of diseases like influenza depends on the mixing patterns within the population, and these mixing patterns depend in part on local factors including the spatial distribution and age structure of the population, the distribution of size and composition of households, employment status and commuting patterns of adults, and the size and age structure of schools. Finally, public health planners must take into account the health behavior patterns of the population, patterns that often vary according to socioeconomic factors such as race, household income, and education levels. Results: FRED (a Framework for Reconstructing Epidemic Dynamics) is a freely available open-source agent-based modeling system based closely on models used in previously published studies of pandemic influenza. This version of FRED uses open-access census-based synthetic populations that capture the demographic and geographic heterogeneities of the population, including realistic household, school, and workplace social networks. FRED epidemic models are currently available for every state and county in the United States, and for selected international locations. Conclusions: State and county public health planners can use FRED to explore the effects of possible influenza epidemics in specific geographic regions of interest and to help evaluate the effect of interventions such as vaccination programs and school closure policies. FRED is available under a free open source license in order to contribute to the development of better modeling tools and to encourage open discussion of modeling tools being used to evaluate public health policies. We also welcome participation by other researchers in the further development of FRED.",10.1186/1471-2458-13-940

Despite good development practices, thorough testing, and proper maintenance policies, a non-negligible number of bugs remain in the released software. Understanding the type of residual bugs is fundamental for adopting proper countermeasures in current and future software releases. Depending on the fault triggering conditions that lead to a failure, developers can introduce fault-tolerance mechanisms and plan verification and validation strategies. In this paper, we analyze bugs in four large open-source software systems during their lifecycle, based on the concept of fault triggers. We first investigate how the type of system affects the bug type proportions, and their evolution over years. Then, an analysis of bug subtypes is performed, so as to better understand their nature, followed by a comparison with respect to attributes such as their average time to fix and severity.",NA
+1773,Article,Free software production as critical social practice,"This paper analyses the phenomenon of free and open source software (FOSS) in the light of Luc Boltanski and Eve Chiapello's The new spirit of capitalism. It argues that collaborative FOSS production by volunteer software developers is a species of critical social practice in Boltanski and Chiapello's sense: rooted in resistance to capitalist social relations, and yet also a source of values that justify the new routes to profitability associated with contemporary network capitalism. Advanced via collective projects that are sustained by hacker norms and privately legislated copyleft' law, the FOSS ethos is apparently antithetical to private property-based accumulation. Yet it can be shown to embody the new spirit of capitalism' in its most distilled form; moreover FOSS developers have instituted new forms of property and new modes of profit creation around software that are in the process of being adapted for use in other economic sectors. Meanwhile, the private law constraints on profit-seeking that have emerged from the FOSS movement are counteracting some of the social pathologies that accompany network capitalism only to consolidate others. The paper concludes by identifying likely bases for a renewal of critique given these realities.",10.1080/03085147.2013.791510

We approach these adoption challenges as a problem of gaining support for organizational innovation. Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are-on average-more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect. Suggestions for PCSS firms are presented and implications for innovation literature are discussed. (C) 2013 Elsevier B.V. All rights reserved.",10.1016/j.respol.2013.04.007

The culture and norms of FLOSS appear to be formulated by what is privileged/marginalized by men in the context of FLOSS, and such men's valuing is likely to threaten women FLOSS participants' face. Our findings are 1) in the FLOSS context, there are gender-based differences in determining what threatens face on the basis of gendered expectations of what is polite, and 2) women-dominated FLOSS participants are ``practically{''} polite in software development practices. These findings were explored through an in-depth analysis of interaction episodes on the email list, archival public interview data of women FLOSS developers, FLOSS development environment, and instructive materials shared in public.

Using detailed data collected from code repositories from Soure-Forge.com, we find that developer team structure and software architecture significantly moderate each other's effect on OSS development performance. Larger teams tend to producemore favorable project performance when the project being developed has a high level of structural interdependency while projects with a low level of structural interdependency require smaller teams in order to achieve better project performance. Meanwhile, centralized teams tend to have a positive impact on project performance when the OSS project has a high level of structural interdependency. However, when a project has a low level of structural interdependency, centralized teams can impair project performance.

However, OSS licenses are very different from those for proprietary software, and our understanding of the choice of OSS licenses is very limited. In this study, we explore this important decision from a learning perspective. We build collaboration networks and trace paths through which potential learning and knowledge flow across projects using a dataset derived from SourceForge. We identify that both experiential learning and vicarious learning have significant influence on OSS license choice. We provide reasons why experiential learning and vicarious learning affect decision-making regarding OSS license choice, and explore important contingencies under which the two modes of learning are more effective. We find that leadership roles on prior projects and similarities between projects significantly moderate these two modes of learning, respectively. More importantly, we argue and empirically illustrate that experiential learning is more effective than vicarious learning in influencing OSS license choice.

In recent years, firms motivated by revenues from software services markets have become the primary contributors to open-source development. In this paper we study the role of services in open source software development and explore the choice between open source and proprietary software. Specifically, our economic model jointly analyzes the investment and pricing decisions of the originators of software and of subsequent open-source contributors. We find that if a contributor is efficient in software development, the originator should adopt an open-source strategy, allowing the contributor to offer higher total quality and capture the higher end of the market while the originator focuses on providing software services to lower end consumers. Conversely, if the contributor is not efficient in development, the originator should adopt a proprietary software development strategy, gaining revenue from software sales and squeezing the contributor out of the services market. In certain cases an increase in originator development efficiency can result in increased contributor profits. Finally, we find that, somewhat counterintuitively, an increase in contributor development efficiency can reduce overall social welfare.",10.1287/isre.2013.0486

With respect to the requirements discipline, the MeRinde process model only uses UML diagrams, and does not offer any guidelines for the Requirements Engineering (capture, analysis, specification, and validation) overall process. This paper proposes an adaptation of the MeRinde requirements discipline, incorporating the use of requirements engineering techniques to complement the final products. Moreover, available free software tools that support the selected techniques are analyzed and discussed using the Systematic Review methodology.

+1818,Article,Micro process analysis of maintenance effort: an open source software case study using metrics based on program slicing,"For any software project, most experts regard the maintenance phase as the most effort and cost intensive of all phases in the software development life cycle. This is due to the high maintenance effort, time, and resources needed to effectively address issues during software maintenance (maintenance activities). Mismanagement of these efforts can lead to the degradation of software maintainability. Understanding the assessment of the related software processes can help sustain or improve maintainability during these maintenance activities. Recent studies have shown that current software process assessments are expensive, generic, and complex, especially for smaller organizations. In this paper, we investigate an alternative software process assessment approach performed by analyzing fine-grained processes (micro processes) of maintenance activities. This approach assesses maintenance efforts based on micro processes in relation to their impact on source code. The approach derives maintenance effort from the complexity and duration of micro processes and uses proposed metrics based on program slicing to measure change impact. In this paper, we investigate an alternative software process assessment approach by analysing fine-grained processes (micro processes) of maintenance activities. At statistically significant levels, results suggest that the level of the maintenance efforts correlates with its impact on source code.

Our analysis used data from github and revealed some regular patterns. We found that the code which newcomers started to contribute with more people engaged in would lead to less contribution in some degree. We also found that there's a relation between developers' early and later period contribution. In addition, developers from different regions were more likely to have dominant relationship.

This can be reached with shared information models providing a comprehensive insight into the entire operated heterogeneous environment. This paper contributes to this vision in two respects. It first introduces a technique for creating a federated information model by inter-relating existing and potentially very different domain specific models. Furthermore, the resulting federated model is used as structural base for defining probabilistic analysis with a Bayesian network. This demonstrates how valuable insights can be obtained through model federation rather than solely relying on separated models reaching only a limited set of information.",10.1109/NGMAST.2013.30
+1823,Article,Modeling the Chemoelectromechanical Behavior of Skeletal Muscle Using the Parallel Open-Source Software Library OpenCMISS,"An extensible, flexible, multiscale, and multiphysics model for nonisometric skeletal muscle behavior is presented. The skeletal muscle chemoelectromechanical model is based on a bottom-up approach modeling the entire excitation-contraction pathway by strongly coupling a detailed biophysical model of a half-sarcomere to the propagation of action potentials along skeletal muscle fibers and linking cellular parameters to a transversely isotropic continuum-mechanical constitutive equation describing the overall mechanical behavior of skeletal muscle tissue. Since the multiscale model exhibits separable time scales, a special emphasis is placed on employing computationally efficient staggered solution schemes. Further, the implementation builds on the open-source software library OpenCMISS and uses state-of-the-art parallelization techniques taking advantage of the unique anatomical fiber architecture of skeletal muscles. OpenCMISS utilizes standardized data structures for geometrical aspects (FieldML) and cellular models (CellML). Both standards are designed to allow for a maximum flexibility, reproducibility, and extensibility. The results demonstrate the model's capability of simulating different aspects of nonisometric muscle contraction and efficiently simulating the chemoelectromechanical behavior in complex skeletal muscles such as the tibialis anterior muscle.",10.1155/2013/517287

+1825,Article,Network ties and the success of open source software development,"Prior network-based research on open source software (OSS) development has focused on the benefit of network ties and assumed all network ties play the same role. We adopt a fine-grained view of network relations to investigate the impact of network ties on the success of OSS development. Through examining the development of OSS projects hosted by SourceForge, we find that co-membership among project teams is an effective mechanism for building network ties, through which knowledge and expertise flows across projects in OSS community and, therefore, contributes to the success of OSS development. However, network ties among projects not only confer benefit, but also incur various cost, and due to the different growth patterns of cost and benefit, network ties have a diminishing return to project success. In addition, we find network ties of leader-follower type and follower-leader type are more beneficial to OSS success than other types of ties, and network ties connecting to projects of later development stages are more beneficial than those connecting to projects of earlier stages. Our study provides useful guidelines and suggestions as to how to leverage the knowledge and expertise of others for successful development of OSS projects. (C) 2013 Elsevier B.V.

We adapt and extend the heterogeneous diffusion model from sociology and examine the conditions under which prior adopters of competing open source software (OSS) licenses socially influence how a new OSS project chooses among such licenses and how the experiences of the project manager of a new OSS project with particular licenses affects its susceptibility to this social influence. We test our predictions using a sample of 5,307 open source projects hosted at SourceForge. Our results suggest the most important factor determining a new project's license choice is the type of license chosen by existing projects that are socially closer to it in its inter-project social network. Moreover, we find that prior adopters of a particular license are more infectious in their influence on the license choice of a new project as their size and performance rankings increase. We also find that managers of new projects who have been members of more successful prior OSS projects and who have greater depth and diversity, of experience in the OSS community are less susceptible to social influence. Finally, we find a project manager is more likely to adopt a particular license type when his or her project occupies a similar social role as other projects that have adopted the same license. These results have implications for research on innovation adoption and diffusion, open source software licensing, and the governance of economic exchange.",10.1287/isre.1120.0449

Traditional approach to teaching these processes has the disadvantage of a presentation largely of information not directly corresponding with the real phenomenon (understanding sectional warping phases). For this purpose requires the use of multimedia presentations for the connection between information and the phenomenon described These presentations can be made classical, in the course room, but for better depth can use different e-learning systems. The purpose of this paper is to present several open source solutions that can be applied to study the processes of weaving (eXe Learning, Hot Potatoes, and so on)., This software can be used to create interactive courses that the student may approach based on complexity.

In this study, we propose and validate two antecedents of organizational investment in internal human capital in the context of OSS adoption. They are (1) firm-specificity of OSS human capital, which denotes the extent to which the internal OSS human capital is strongly tied to the organization and cannot be equally well applied in other organizations, and (2) learning-related scale, which reflects the extent to which the organizational cost of learning OSS can be spread by applying the knowledge gained to other projects and business functions within the organization. Survey data collected from 114 senior Information Technology (IT) managers and professionals indicates that these two factors are positively associated with the investment in cultivating internal OSS human capital.",10.1080/08874417.2013.11645670

Influenced by the ``creative elements{''} of OSS, individuals in organizations often forget that the end result of software implementation is to improve productivity, thereby creating a negative impression on OSS implementation strategy as a whole. In this study, we argue that fit between the individual's task, values and work demands can influence or hinder the sustained use of OSS. We explore how task-technology fit and two dimensions of person-organization fit (value-based fit and demand-ability fit) interact with each other to influence productivity performance. Using survey data, we find that congruence between the organization's OSS values and the individual user's OSS values (value-based fit), decreases productivity performance, whereas, fit between an individual's OSS skills and the organizational task demands (demandability fit), increases productivity performance.

However, in a research context it would often be useful to be able to modify this code and/or to have full control over all these parameters from researcher-written software.

This results in multiple versions or evolving nature of a software. Identification of parts of a software that are more prone to changes than others is one of the important activities. Identifying change prone classes will help developers to take focused and timely preventive actions on the classes of the software with similar characteristics in the future releases.

We collected a set of OO metrics and change data of each class that appeared in two versions of an open source dataset, `Java TreeView', i.e., version 1.1.6 and version 1.0.3. Besides this, we have also predicted various models that can be used to identify change prone classes, using machine learning and statistical techniques and then compared their performance. The results are analyzed using Area Under the Curve (AUC) obtained from Receiver Operating Characteristics (ROC) analysis. The results show that the models predicted using both machine learning and statistical methods demonstrate good performance in terms of predicting change prone classes.

Open source software solutions offer great opportunities for cost reduction and quality improvement, especially for small and medium enterprises that typically have to address major difficulties due to the limited resources available for selecting and adopting a new software system. Objective: This paper aims to provide support for selecting the open source software that is most suitable to the specific needs of an enterprise from among the options offering equivalent or overlapping functionality. Method: This paper proposes a framework for evaluating the quality and functionality of open source software systems. The name of the framework is EFFORT (Evaluation Framework for Free/Open souRce projecTs). It supports the evaluation of product quality, community trustworthiness and product attractiveness. The framework needs to be customised to the analysis of software systems for a specific context. Results: The paper presents the customisation of EFFORT for evaluating Enterprise Resource Planning (ERP) open source software systems. The customised framework was applied to the evaluation and comparison of five ERP open source software systems. The results obtained permitted both the refinement of the measurement framework and the identification of the ERP open source software system that achieved the highest score for each chosen characteristic. Conclusion: EFFORT is a useful tool for evaluating and selecting an open source software system. It may significantly reduce the amount of negotiation conducted among an enterprise's members and reduce the time and cost required for gathering and interpreting data. The EFFORT framework also considers the users' opinions by introducing relevance markers associated with the metrics and questions in the data aggregation process. (C) 2013 Elsevier B.V.

+1862,Article,Rallying competencies in virtual communities: A study of core processes and user interest in open source software projects,"Managing work practices has become one of the key challenges facing virtual communities. This paper seeks to broaden the research on virtual communities by applying the theory of competency rallying (TCR) in a longitudinal manner to examine the impact of task identification, task assignment, task execution and task management on user interest in open source software (OSS) projects defined by popularity and communication. The aim of this paper is: (I) re-conceptualizing the concept of user interest and broadening our understanding of user interest by incorporating users' post-usage behaviors, (2) examining the effect of various tasks involved in an OSS project's key processes of defect-fixing and feature-enhancement on user interest. The current study found that project popularity is positively influenced by task assignment, task execution and task management. Additionally, user communication was found to be positively impacted by task identification and task execution. The data collected from 1178 OSS projects in a longitudinal manner (at 3 time points over a period of 16 months) confirmed the expectations from TCR and also demonstrated that over time the effects that development of competencies and managing short term cooperative work have on project success might increase, while the impact of identifying market needs and marshalling competencies may not significantly change.

+1864,InProceedings,"Reflexivity, Raymond, and the success of open source software development: a SourceForge empirical study","Context: Conventional wisdom, inspired in part by Eric Raymond, suggests that open source developers should---and primarily do---develop software for developers like themselves. We refer to the production of software primarily for the benefit of developers as reflexivity, and we evaluate the applicability of this concept to open source software (OSS) by studying SourceForge projects. Objective: The goal of this research is to test Eric Raymond's assertions with respect to OSS success factors. Method: We present four criteria by which to assess project reflexivity in SourceForge. These criteria are based on three specific indicators: intended audiences, relevant topics, and supported operating systems. Results: We show in this short paper that 68\\% of SourceForge projects are likely reflexive (in the sense described by Raymond). Further, 76\\% of projects exceeding one million downloads are reflexive, 79\\% for projects exceeding ten million downloads, and 89\\% for projects exceeding one hundred million downloads. Conclusion: These results tentatively support Raymond's assertions that 1) OSS projects tend to be reflexive and 2) reflexive OSS projects tend to be more successful than irreflexive projects. Causality, however, is not addressed.",10.1145/2460999.2461036
+1865,Article,Reliability assessment based on hazard rate model for an embedded OSS porting-phase,"Embedded Open Source Software (OSS) systems have been gaining a lot of attention in the embedded system area. The successful experience of embedded OSSs include Android, BusyBox, TRON, etc. Also, OSS market will be expanded not only to mobile phone OSS areas but also to other embedded OSS areas in the future. However, the poor handling of quality problem and customer support prohibit the progress of embedded OSS. Also, it is difficult for developers to assess the reliability and portability of embedded OSS on a single-board computer. A method of software reliability assessment based on flexible hazard rate modeling for the embedded OSS is proposed in this paper. Also, several numerical examples are shown by using actual data. Moreover, this paper compares the proposed model with the conventional hazard rate models by using the comparison criteria of goodness-of-fit.

BMSCs obtained from rabbits were transfected with bFGF gene-encoding plasmids and proliferation rate and the differentiation marker alkaline phosphatase activity were measured. Following seeding into Bio-Oss collagen and 9-day culture in vitro, the surface morphology of the Bio-Oss was assessed using scanning electron microscopy analysis. Three mandibular defects were induced in the lower border of the bilateral mandibular ramus in each New Zealand white rabbit (total n=6). Three scaffolds, group A (seeded with BMSCs/bFGF), B (seeded with BMSCs/pVAX1) and C (cell-free), which had been cultured in vitro under standard cell culture conditions for 18 days, were implanted into mandibular defects under sterile conditions. Animals were sacrificed by anesthesia overdose 12 weeks following surgery and the scaffolds were extracted for bone mineral density and histological analyses. Results indicate that bFGF was successfully transfected into BMSCs. Proliferation and osteoblast differentiation of BMSCs were stimulated by bFGE: in vitro. No differences were identified in surface morphology for Bio-Oss loaded with variable groups of cells. At week 12 following implantation of Bio-Oss scaffolds, mineralization of BMSCs in Bio-Oss scaffolds was observed to be increased by bFGF. New bone and cartilage formation was revealed in hematoxylin and eosin-stained sections in Bio-Oss scaffolds and was most abundant in group A (BMSCs transfected with bFGF). In the current study, the bFGF gene was transfected into BMSCs and expressed successfully. bFGF promoted proliferation and differentiation of BMSCs in vitro and implantation of bFGF-expressing BMSCs combined with Bio-Oss enhanced new bone regeneration more effectively than traditional methods.",10.3892/mmr.2012.1171

One way this problem can be mitigated is by growing student-oriented open source projects within academia while still involving real world clients. One such project, called Homebase, involved a team of students working with a local Ronald McDonald House to develop volunteer scheduling software. In true open source fashion, this project has since been extended over a number of course iterations, with different clients, and has been adopted at other schools. In this paper, we report on our experiences using this approach for similar projects at three quite different schools, and discuss ways to adapt and enhance this approach for differing student populations.",NA

+1870,InProceedings,Social Activities Rival Patch Submission For Prediction of Developer Initiation in OSS Projects,"Maintaining a productive and collaborative team of developers is essential to Open Source Software (OSS) success, and hinges upon the trust inherent among the team. Whether a project participant is initiated as a developer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e. g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving developer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e. OSS developers patch submission activities. We use these sets to predict whether a project participant will become a developer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a developer. Further, we find that this is true to the extent that other predictors, e. g. patch submission info, need not be included in the models. In addition, we show that future developers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10\\% of the three month data's predictions. Finally, we find that it is easier to become a developer earlier in the projects lifecycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.",10.1109/ICSM.2013.45

+1874,Article,Studying re-opened bugs in open source software,"Bug fixing accounts for a large amount of the software maintenance resources. Generally, bugs are reported, fixed, verified and closed. However, in some cases bugs have to be re-opened. Re-opened bugs increase maintenance costs, degrade the overall user-perceived quality of the software and lead to unnecessary rework by busy practitioners. In this paper, we study and predict re-opened bugs through a case study on three large open source projects-namely Eclipse, Apache and OpenOffice. We structure our study along four dimensions: (1) the work habits dimension (e.g., the weekday on which the bug was initially closed), (2) the bug report dimension (e.g., the component in which the bug was found) (3) the bug fix dimension (e.g., the amount of time it took to perform the initial fix) and (4) the team dimension (e.g., the experience of the bug fixer). We build decision trees using the aforementioned factors that aim to predict re-opened bugs. We perform top node analysis to determine which factors are the most important indicators of whether or not a bug will be re-opened. Our study shows that the comment text and last status of the bug when it is initially closed are the most important factors related to whether or not a bug will be re-opened. Using a combination of these dimensions, we can build explainable prediction models that can achieve a precision between 52.1-78.6 \\% and a recall in the range of 70.5-94.1 \\% when predicting whether a bug will be re-opened. We find that the factors that best indicate which bugs might be re-opened vary based on the project. The comment text is the most important factor for the Eclipse and OpenOffice projects, while the last status is the most important one for Apache. These factors should be closely examined in order to reduce maintenance cost due to re-opened bugs.",10.1007/s10664-012-9228-6

+1881,InProceedings,TECHNOLOGY ENHANCED LEARNING WITH OPEN SOURCE SOFTWARE FOR SCIENTISTS AND ENGINEERS,"This paper represents the evaluation and integration of Open Source Software (OSS) technologies to enhance the learning of engineers and scientists within the university. The utilization of OSS is essential as costs around the world continue to rise for education, institutions must become innovative in the ways they teach and grow Science, Technology, Engineering, \\& Mathematics (STEM) majors. To do this effectively professors and administrative staff should push toward the utilization of OSS and other available tools to enhance or supplement currently available tools with minimal integration costs. The OSS applications would allow students the ability to learn critical technological skills for success at small fraction of the cost. OSS also provides faculty members the ability to have students dissect source code, analyze network traffic, create virtual instances of real Operating Systems (OSs), and prepare students for low level software development. It is critical that all institutions look at alternatives in providing training and delivering educational material regardless of limitations going forward as the world continues to be more global due to the increased use of technologies everywhere. Through reviewing the available technology, possible implementations of these technologies, and the application of these items in industry could provide a starting point in integrating these tools into academia.

Our findings show that the life cycles of OSSDC display an inverted-U shape in terms of effectiveness level and an inverted-S shape in terms of activity level. Although our results provide some evidence of distinct states, they do not imply that such states are predetermined or irreversible. On the contrary, these numerous states are viewed here as intrinsically dynamic. These findings not only give empirical support to the organizational life cycle metaphor in the context of OSSDC, but also aid practitioners and policy-makers in assessing online communities. Taking an open systems view of organizations, this study aids in reconciling some issues in life cycle theory, such as the irreversibility and pre-determinacy of life cycle models, and adds to a young but fast growing stream of literature on open source projects.

The effects of trust on developers' intention to remain with their projects have been studied. However, little is known about its conceptual counterpart, distrust. This dearth of knowledge motivates our research. First, we studied what OSS project features affect trust and distrust among developers. Second, we examined how trust and distrust influence developers' intention to continue participating. We tested our hypotheses with 451 data points from an online survey.

+1890,Article,The Evolving Role of Open Source Software in Medicine and Health Services,"The past five decades have witnessed immense coevolution of methods and tools of information technology, and their practical and experimental application within the medical and healthcare domain. Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-forprofit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries.

Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team. The results provide guidance for practitioners about how to combine 19 identified governance mechanisms into effective project governance that stimulates productive participation.",10.2753/MIS0742-1222300303

+1897,Article,The attraction of contributors in free and open source software projects,"As firms increasingly sanction an open sourcing strategy, the question of which open source project to undertake remains tentative. The lack of established metrics makes it difficult to formulate such strategy. While many projects have been formed and created, only a few managed to remain active. With the majority of these projects failing, firms need a reliable set of criteria to assess what makes a project appealing not only to developers but also to visitors, users and commercial sponsors. In this paper, we develop a theoretical model to explore the contextual and causal factors of project attractiveness in inducing activities such as source code contribution, software maintenance, and usage. We test our model with data derived from more than 4000 projects spanning 4 years. Our main findings include that projects' set of conditions such as license restrictiveness and their available resources provide the context that directly influence the amount of work activities observed in the projects. It was also found that indirect and unintended contributions such as recommending software, despite of being non-technical, cannot be ignored for project activeness, diffusion and sustainability. Finally, our analysis provide evidence that higher attractiveness leads to more code-related activities with the downside of slowing down responsiveness to address projects' tasks, such as the implementation of new features and bug fixes. Our model underscores the significance of the reinforcing effects of attractiveness and work activities in open source projects, giving us the opportunity to discuss strategies to manage common traps such as the liability of newness. We conclude by discussing the applicability of the research model to other user-led initiatives. (C) 2012 Elsevier B.V. All rights reserved.",10.1016/j.jsis.2012.07.004

Estimates of structural parameters of Exponential Random Graph Models for two-mode networks reveal the structural logics shaping activities of collaborative problem solving. After controlling for contributor-specific and software bug-specific characteristics, we find that contributors ({''}problem solvers{''}) tend to distribute their activity over multiple software bugs. At the same time, however, we find that software bugs ({''}problems{''}) tend not to share multiple contributors. This dual tendency toward de-specialization and exclusivity is sustained by specific local network dependencies revealed by our analysis which also suggests possible organizational mechanisms that may be underlying the puzzling macro-structural regularities frequently observed, but rarely explained, in the production of open source software. By combining these mechanisms with the influence of contributors characterized by different levels of involvement in the project, we provide micro-level evidence of structural interdependence between ``core{''} and ``peripheral{''} members identified exclusively on the basis of their individual level of contribution to the project.

+1902,InProceedings,The dual role of conflict in free and open source software development,"The voluntary and computer mediated nature of FOSS work presents unique challenges and opportunities for effective collaboration. Conflict is one such challenge, magnified by the distributed nature of work and limited communication channels. Though conflict is recognized as an important social process in FOSS development teams, few studies have adequately addressed this issue. Drawing on theoretical frameworks in organizational behavior and social psychology, her dissertation investigates how conflict arises in voluntary distributed virtual teams such as FOSS, and its impact on group function. The work first explores the emergence and experience of conflict during the life cycle of a project. Different types and sources of conflict are identified, as well as their relationship with group outcomes. Various conflict types are expected to affect group function differently: some conflict sources may present a challenge, while others may prove necessary for successful group function. The dissertation expands theory and research on distributed work, in examining on-going processes of conflict in voluntary teams. This work also informs community design, as understanding conflict antecedents in voluntary virtual teams aids in reducing unproductive conflict and facilitates conflict that spurs innovation.",10.1145/2491055.2491090
+1903,Article,The evolution of OSS governance: a dimensional comparative analysis,"The competiveness of Open Source Software (OSS) communities depends on the quantity and combination of resources and competencies attracted to and retained at each stage of the innovation process. To this purpose, given the lack of proprietary control over source code, the way mechanisms of governance combine through a coherent and emergent process of governance is important to shaping the attractiveness and sustainability of these communities. Despite their importance, we still know little about how governance mechanisms are combined in 055 communities. This paper contributes to filling part of that gap. The study is based on an explorative factor analysis conducted on a database of 40 case studies of OSS projects hosted in Freshmeat. The results show OSS governance is configurational, and highlights four likely configurations of governance. (C) 2012 Elsevier Ltd. All rights reserved.",10.1016/j.scaman.2012.10.003
+1905,Article,The use and role of open source software applications in public and not-for-profit hospitals in the United States,"Background: The potential cost savings and customizability of open source software (OSS) may be particularly attractive for hospitals. However, numerous health-care-specific OSS applications exist, the adoption of OSS health information technology (HIT) applications is not widespread in the United States. Purpose: This disconnect between the availability of promising software and low adoption raises the basic question: If OSS HIT is so advantageous, why are more health care organizations not using it? Methodology: We interviewed the chief information officer, or equivalent position, at 17 not-for-profit and public hospitals across the United States. Through targeted recruitment, our sample included nine hospitals using OSS HIT and eight hospitals not using OSS HIT. The open-ended interview questions were guided by domains included in the fit-viability theory, an organizational-level innovation adoption framework, and those suggested by a review of the literature. Transcripts were analyzed using an inductive and comparative approach, which involved an open coding for relevant themes. Findings: Interviews described the state of OSS use in hospitals. Specifically, general OSS applications were widely used by IT professionals. In addition, hospitals using OSS HIT still relied heavily on vendor support. In terms of why decisions arose to use OSS HIT, several hospitals using OSS HIT noted the cost advantages. In contrast, hospitals avoiding OSS HIT were clear, OSS as a class did not fit with clinical work and posed too much risk. Practice Implications: Perceptions of OSS HIT ranged from enthusiastic embracement to resigned adoption, to refusal, to abandonment. Some organizations were achieving success with their OSS HIT choices, but they still relied on vendors for significant support. The decision to adopt OSS HIT was not uniform but contingent upon views of the risk posed by the technology, economic factors, and the hospital's existing capabilities.",10.1097/HMR.0b013e318276f9ed
+1908,Article,The {Evolving} {Role} of {Open} {Source} {Software} in {Medicine} and {Health} {Services},"The past five decades have witnessed immense coevolution of methods and tools of information technology, and their practical and experimental application within the medical and healthcare domain. Healthcare itself continues to evolve in response to change in healthcare needs, progress in the scientific foundations of treatments, and in professional and managerial organization of affordable and effective services, in which patients and their families and carers increasingly participate. Taken together, these trends impose highly complex underlying challenges for the design, development, and sustainability of the quality of supporting information services and software infrastructure that are needed. The challenges are multidisciplinary and multiprofessional in scope, and they require deeper study and learning to inform policy and promote public awareness of the problems health services have faced in this area for many years. The repeating pattern of failure to live up to expectations of policy-driven national health IT initiatives has proved very costly and remains frustrating and unproductive for all involved. In this article, we highlight the barriers to progress and discuss the dangers of pursuing a standardization framework devoid of empirical testing and iterative development. We give the example of the openEHR Foundation, which was established at University College London (UCL) in London, England, with members in 80 countries. The Foundation is a not-for-profit company providing open specifications and working for generic standards for electronic records, informed directly by a wide range of implementation experience. We also introduce the Opereffa open source framework, which was developed at UCL based on these specifications and which has been downloaded in some 70 countries. We argue that such an approach is now essential to support good discipline, innovation, and governance at the heart of medicine and health services, in line with the new mandate for health commissioning in the United Kingdom's National Health Service (NHS), which emphasizes patient participation, innovation, transparency, and accountability.",NA

Drawing an overly technical distinction between these two categories of labor potentially overlooks some important aspects of the processes of capitalist reproduction, particularly the increasingly social character of labor, and as such, a broader definition must be considered. The labor engaged in the production of Free and Open Source Software (FOSS) is illustrative of this need for further examination of the productive-unproductive distinction, for the fact that though FOSS, in some respects, appears tendentially anti-capitalist, in fact, it, and the immaterial labor driving it, has essentially been fully subsumed in the apparatus of capital accumulation.

+1913,InProceedings,"Together but apart: how spatial, temporal and cultural distances affect FLOSS developers' project retention","Companies rely more and more on virtual teams which consist of globally dispersed members. Unfortunately, members' separation can raise considerable interpersonal challenges. In order to prevent conflicts from deescalating and ensure effective teamwork, companies pay careful attention to the management of members' spatial, temporal and cultural distances. While initiatives developing Free Libre Open Source Software (FLOSS) similarly combine a worldwide distributed workforce, relatively little is known about how members' separation affects their collaboration. However, without such an understanding no adequate advice can be derived for managers of FLOSS initiatives on how to foster members' collaboration and retention. Building on lessons learned from the organizational domain this research hypothesizes that spatial, temporal and cultural distances are key factors for FLOSS developers' team integration and project retention. To evaluate our research hypotheses, we study FLOSS developers' contribution and conversation behavior and extract objective figures on their spatial, temporal and cultural distances to each other.",10.1145/2487294.2487330

Investigating the types of norms that exist in open source projects and their efficacy i.e. the usage of norms in enabling smoother functioning however has not received much attention from the normative multi-agent systems NorMAS community. This paper makes two contributions in this regard. First, it presents norm compliance results from a case study involving three open source Java projects. Second, it presents an architecture for mining norms from open source projects. It also discusses the opportunities presented by the domain of software repositories for the study of norms. In particular, it points towards how norms can be mined by leveraging and extending prior work in the areas of Normative Multi-Agent Systems NorMAS and mining software repositories.",10.1007/978-3-642-55192-5_3
+1915,Article,Towards a better understanding of software evolution: an empirical study on open-source software,"Software evolution is a fact of life. Over the past 30years, researchers have proposed hypotheses on how software changes and provided evidence that both supports and refutes these hypotheses. To paint a clearer image of the software evolution process, we performed an empirical study on long spans in the lifetime of nine open-source projects. Our analysis covers 705 official releases and a combined 108years of evolution. We first tried to confirm Lehman's eight laws of software evolution on these projects using statistical hypothesis testing. Our findings indicate that only the laws of continuing change and continuing growth are confirmed for all programs, whereas the other six laws are violated by some programs, or can be both confirmed and invalidated, depending on the laws' operational definitions. Second, we analyze the growth rate for projects' development and maintenance branches, and the distribution of software changes. We find similarities in the evolution patterns of the programs we studied, which brings us closer to constructing rigorous models for software evolution.

+1916,Article,"Trends in Free, Libre, Open Source Software Communities: From Volunteers to Companies","The first free/libre/open source software (FLOSS) development communities were composed almost exclusively of volunteers. They were individuals who, despite their affiliation, contributed to the project on their own. They decided which project to join, and their contributions were personal in nature, even when in some cases they were employees of companies with some interests in the project. GNU, the first of such communities, and some others that emerged during the late 1980s and 1990s, followed this pattern. During the 1990s corporate interests started to have a role in some FLOSS communities. Companies hired people from those communities to gain influence, or tasked their employees to contribute to them, again with the idea of influencing their decisions. During the 2000s, corporate communities, in which companies are first-class citizens, have emerged, changing the rules and redefining the role of volunteers and non-affiliated individuals. However, the role of developers, with independence of the company for which they work, is still important even in these communities. This paper addresses this transition from volunteer-based to company-based development communities, and explores the structure and behavior of the latter.",10.1515/itit.2013.1012
+1917,Article,Tri-track: Free Software for Large-Scale Particle Tracking,"The ability to correctly track objects in time-lapse sequences is important in many applications of microscopy. Individual object motions typically display a level of dynamic regularity reflecting the existence of an underlying physics or biology. Best results are obtained when this local information is exploited. Additionally, if the particle number is known to be approximately constant, a large number of tracking scenarios may be rejected on the basis that they are not compatible with a known maximum particle velocity. This represents information of a global nature, which should ideally be exploited too. Some time ago, we devised an efficient algorithm that exploited both types of information. The tracking task was reduced to a max-flow min-cost problem instance through a novel graph structure that comprised vertices representing objects from three consecutive image frames. The algorithm is explained here for the first time. A user-friendly implementation is provided, and the specific relaxation mechanism responsible for the method's effectiveness is uncovered. The software is particularly competitive for complex dynamics such as dense antiparallel flows, or in situations where object displacements are considerable. As an application, we characterize a remarkable vortex structure formed by bacteria engaged in interstitial motility.",10.1017/S1431927612014328
+1918,Article,UMMPerfusion: an Open Source Software Tool Towards Quantitative MRI Perfusion Analysis in Clinical Routine,"To develop a generic Open Source MRI perfusion analysis tool for quantitative parameter mapping to be used in a clinical workflow and methods for quality management of perfusion data. We implemented a classic, pixel-by-pixel deconvolution approach to quantify T1-weighted contrast-enhanced dynamic MR imaging (DCE-MRI) perfusion data as an OsiriX plug-in. It features parallel computing capabilities and an automated reporting scheme for quality management. Furthermore, by our implementation design, it could be easily extendable to other perfusion algorithms. Obtained results are saved as DICOM objects and directly added to the patient study. The plug-in was evaluated on ten MR perfusion data sets of the prostate and a calibration data set by comparing obtained parametric maps (plasma flow, volume of distribution, and mean transit time) to a widely used reference implementation in IDL. For all data, parametric maps could be calculated and the plug-in worked correctly and stable. On average, a deviation of 0.032 +/- 0.02 ml/100 ml/min for the plasma flow, 0.004 +/- 0.0007 ml/100 ml for the volume of distribution, and 0.037 +/- 0.03 s for the mean transit time between our implementation and a reference implementation was observed. By using computer hardware with eight CPU cores, calculation time could be reduced by a factor of 2.5. We developed successfully an Open Source OsiriX plugin for T1-DCE-MRI perfusion analysis in a routine quality managed clinical environment. Using model-free deconvolution, it allows for perfusion analysis in various clinical applications. By our plug-in, information about measured physiological processes can be obtained and transferred into clinical practice.",10.1007/s10278-012-9510-6

+1927,InProceedings,What Effect does Distributed Version Control have on OSS Project Organization?,"Many Open Source Software (OSS) projects are moving form Centralized Version Control (CVC) to Distributed Version Control (DVC). The effect of this shift on project organization and developer collaboration is not well understood. In this paper, we use a theoretical argument to evaluate the appropriateness of using DVC in the context of two very common organization forms in OSS: a dictatorship and a peer group. We find that DVC facilitates large hierarchical communities as well as smaller groups of developers, while CVC allows for consensus-building by a peer group. We also find that the flexibility of DVC systems allows for diverse styles of developer collaboration. With CVC, changes flow up and down (and publicly) via a central repository. In contrast, DVC facilitates collaboration in which work output can flow sideways (and privately) between collaborators, with no repository being inherently more important or central. These sideways flows are a relatively new concept. Developers on the Linux project, who tend to be experienced DVC users, cluster around ``sandboxes:{''} repositories where developers can work together on a particular topic, isolating their changes from other developers. In this work, we focus on two large, mature OSS projects to illustrate these findings. However, we suggest that social media sites like GitHub may engender other original styles of collaboration that deserve further study.",NA

+1931,Article,goGPS: open source software for enhancing the accuracy of low-cost receivers by single-frequency relative kinematic positioning,"goGPS is a free and open source satellite positioning software package aiming to provide a collaborative platform for research and teaching purposes. It was first published in 2009 and since then several related projects are on-going. Its objective is the investigation of strategies for enhancing the accuracy of low-cost single-frequency GPS receivers, mainly by relative positioning with respect to a base station and by a tailored extended Kalman filter working directly on code and phase observations. In this paper, the positioning algorithms implemented in goGPS are presented, emphasizing the modularity of the software design; two specific strategies to support the navigation with low-cost receivers are also proposed and discussed, namely an empirical observation weighting function calibrated on the receiver signal-to-noise ratio and the inclusion of height information from a digital terrain model as an additional observation in the Kalman filter. The former is crucial when working with high-sensitivity receivers, while the latter can significantly improve the positioning in the vertical direction. The overall goGPS positioning accuracy is assessed by comparison with a dual-frequency receiver and with the positioning computed by a standard low-cost receiver. The benefits of the calibrated weighting function and the digital terrain model are investigated by an experiment in a dense urban environment. It comes out that the use of goGPS and low-cost receivers leads to results comparable with those obtained by higher level receivers; goGPS has good performances also in a dense urban environment, where its additional features play an important role.",10.1088/0957-0233/24/11/115010

Open sourcing software developments means sharing technology and resources with communities worldwide to help eliminate the digital divide, create economic opportunity, and support equal access to technology. Therefore, a methodological approach is needed to assess properly the performance and the value generation potential and to put such measure into organizational reports. International financial reporting framework is checked over conditions to allow value recognition of open sourced assets. Linux kernel development value is estimated to reflect worth of open source developments despite absence of book value due to inexistence of a single cost source. Several attempts to estimate a valuation of open source software have been performed previously. However, this study is the first to judge suitability of accounting framework to report on this value.

Measurements of these metrics tell us various key aspects of system. This in turn supports knowledgeable decision making by which we can enhance the quality of system. Maintenance is a process of revisions or corrections made to software systems after their first release. The key feature of software development is change. Hence it is important to develop software that is easy to modify and is thus maintainable. This paper evaluates the existing Oman and Hagemeister maintainability index model which calculates maintainability index (MI) based on Cyclomatic Complexity, Lines of code and Halsted volume. For this purpose, software metric datasets of Lucene, which is open source software of 163085 lines of code are used, and it is shown that the existing Oman and Hagemeister maintainability index mode model is not a good a predictor of maintainability. A new maintainability index model is proposed with a new set of predictor metrics. The new proposed model is a marked improvement over the existing Oman and Hagemeister maintainability index model.

+1943,Article,A Situated Approach of Roles and Participation in Open Source Software Communities,"Our research aims at understanding the various forms of participation in Open Source Software (OSS) design, seen as distributed design in online spaces of actions-discussion, implementation, and boundary between these spaces. We propose a methodology-based on situated analyses of a formal design process used in the Python project-to identify the distribution of actual roles (implementation, interactive, group, and design oriented) performed by participants into and between the spaces (defining boundary spaces). This notion of roles is grounded in collaborative design activities performed online by participants. This way, our findings complete the core-periphery model of participation in OSS. Concerning the distribution of roles between spaces, we reveal a map of participation in OSS: The majority of participants are pure discussants, but all participants in the implementation spaces do also act in the discussion space, and few participants act at boundary spaces. Concerning the distribution of roles between participants in the discussion space, we reveal that interactions are structured by a central hub (occupied by key participants) and that, whereas design-oriented roles are spread among all participants, group-oriented roles are performed by one or two participants in the respective spaces and at their boundary. Finally, combination of roles reveals five individual profiles performed by participants. Our approach could be extended to other design situations to explore relationships between forms of participation-in particular, those revealing use-oriented contributions-performance, and quality of the design product.

It applies to well-mixed surface water layers, including the epilimnion of stratified lakes, and the output data are average values over the considered water column. Based on intermediate formation yields from the parent compound via the different photochemical pathways, the software can also predict intermediate formation kinetics and overall yield. APEX is based on a photochemical model that has been validated against available field data of pollutant phototransformation, with good agreement between model predictions and field results. The APEX software makes allowance for different levels of knowledge of a photochemical system. For instance, the absorption spectrum of surface water can be used if known, or otherwise it can be modelled from the values of DOC. Also the direct photolysis quantum yield can be entered as a detailed wavelength trend, as a single value (constant or average), or it can be defined as a variable if unknown. APEX is based on the free software Octave. Additional applications are provided within APEX to assess the sigma-level uncertainty of the results and the seasonal trend of photochemical processes.",10.1039/c3em00541k
+1952,InProceedings,AUTOMATIC IMAGE REGISTRATION USING FREE AND OPEN SOURCE SOFTWARE,"Image registration is the most critical operation in remote sensing applications to enable location based referencing and analysis of earth features. This is the first step for any process involving identification, time series analysis or change detection using a large set of imagery over a region. Most of the reliable procedures involve time consuming and laborious manual methods of finding the corresponding matching features of the input image with respect to reference. Also the process, as it involves human interaction, does not converge with multiple operations at different times. Automated procedures rely on accurately determining the matching locations or points from both the images under comparison and the procedures are robust and consistent over time. Different algorithms are available to achieve this, based on pattern recognition, feature based detection, similarity techniques etc. In the present study and implementation, Correlation based methods have been used with a improvement over newly developed technique of identifying and pruning the false points of match. Free and Open Source Software (FOSS) have been used to develop the methodology to reach a wider audience, without any dependency on COTS (Commercially off the shelf) software. Standard deviation from foci of the ellipse of correlated points, is a statistical means of ensuring the best match of the points of interest based on both intensity values and location correspondence. The methodology is developed and standardised by enhancements to meet the registration requirements of remote sensing imagery. Results have shown a performance improvement, nearly matching the visual techniques and have been implemented in remote sensing operational projects. The main advantage of the proposed methodology is its viability in production mode environment. This paper also shows that the visualization capabilities of MapWinGIS, GDAL's image handling abilities and OSSIM's correlation facility can be efficiently integrated to effectively use in remote sensing based production environment.",10.5194/isprsarchives-XL-8-1121-2014
+1953,Article,Acceptance of monetary rewards in open source software development,"The open source software (OSS) movement thrives on innovation and volunteer effort of developers. Scholars have expressed widespread concern about the sustainability of the OSS movement due to high levels of volunteerism. In this paper, we address a central challenge to the sustainability of OSS-developers' acceptance of monetary rewards. We strive to explain why some OSS developers accept monetary rewards and others do not. Viewed through the theoretical lens of the private-collective innovation model (Von Hippel and Von Krogh, 2003, 2006), this allows us to describe when developers will accept private financial rewards. Our main research objective is to clearly map the web of relationships between causal antecedents, and developers' acceptance behavior. Using a unique dataset that combines survey and behavioral measures, we find that - (a) intention to accept monetary rewards mediates the impact of motivational elements on developers' acceptance of monetary rewards; (b) intrinsic and extrinsic motivations positively affect their intention to accept monetary rewards, community motivation negatively impacts intention and ideological motivation does not affect the intention to accept rewards and (c) these effects are obtained even after inclusion of several control variables. The theoretical and managerial implications of our work are described. (C) 2013 Elsevier B.V. All rights reserved.",10.1016/j.respol.2013.10.007

+1957,InProceedings,Adoption of Free Libre Open Source Software (FLOSS): A Risk Management Perspective,"Free Libre Open Source Software (FLOSS) has become a strategic asset in software development, and open source communities behind FLOSS are a key player in the field. The analysis of open source community dynamics is a key capability in risk management practices focused on the integration of FLOSS in all types of organizations. We are conducting research in developing methodologies for managing risks of FLOSS adoption and deployment in various application domains. This paper is about the ability to systematically capture, filter, analyze, reason about, and build theories upon, the behavior of an open source community in combination with the structured elicitation of expert opinions on potential organizational business risk. The novel methodology presented here blends together qualitative and quantitative information as part of a wider analytics platform. The approach combines big data analytics with automatic scripting of scenarios that permits experts to assess risk indicators and business risks in focused tactical and strategic workshops. These workshops generate data that is used to construct Bayesian networks that map data from community risk drivers into statistical distributions that are feeding the platform risk management dashboard. A special feature of this model is that the dynamics of an open source community are tracked using social network metrics that capture the structure of unstructured chat data. The method is illustrated with a running example based on experience gained in implementing our approach in an academic smart environment setting including Moodbile, a Mobile Learning for Moodle (www.moodbile.org). This example is the first in a series of planned experiences in the domain of smart environments with the ultimate goal of deriving a complete risk model in that field.",10.1109/COMPSAC.2014.25

We found that, contrary to our expectations, the overall quality of the code is not affected by the size of the code base, but that it was negatively impacted by the growth of the number of code contributors. Our results also show that projects with more core developers don't necessarily have better code quality.",NA

The sensor network uses OpenWRT, an embedded Linux operating system, and other open source software, to create a modified router for reading Maxim's 1-Wire (TM) protocol, queuing and transferring standardized sensor data while enabling location and time. The modified router created the bridge between the sensor protocols and the middle-level software to provide reliable data to both the sewer district and the Environmental Protection Agency. Representational State Transfer (REST) is used in the design philosophy of the client and server open source software for transferring the data from the embedded systems to the server level for storage and publication.

+1968,Article,An open source software for fast grid-based data-mining in spatial epidemiology (FGBASE),"Background: Examining whether disease cases are clustered in space is an important part of epidemiological research. Another important part of spatial epidemiology is testing whether patients suffering from a disease are more, or less, exposed to environmental factors of interest than adequately defined controls. Both approaches involve determining the number of cases and controls (or population at risk) in specific zones. For cluster searches, this often must be done for millions of different zones. Doing this by calculating distances can lead to very lengthy computations. In this work we discuss the computational advantages of geographical grid-based methods, and introduce an open source software (FGBASE) which we have created for this purpose. Methods: Geographical grids based on the Lambert Azimuthal Equal Area projection are well suited for spatial epidemiology because they preserve area: each cell of the grid has the same area. We describe how data is projected onto such a grid, as well as grid-based algorithms for spatial epidemiological data-mining. The software program (FGBASE), that we have developed, implements these grid-based methods. Results: The grid based algorithms perform extremely fast. This is particularly the case for cluster searches. When applied to a cohort of French Type 1 Diabetes (T1D) patients, as an example, the grid based algorithms detected potential clusters in a few seconds on a modern laptop. This compares very favorably to an equivalent cluster search using distance calculations instead of a grid, which took over 4 hours on the same computer. In the case study we discovered 4 potential clusters of T1D cases near the cities of Le Havre, Dunkerque, Toulouse and Nantes. One example of environmental analysis with our software was to study whether a significant association could be found between distance to vineyards with heavy pesticide. None was found. In both examples, the software facilitates the rapid testing of hypotheses. Conclusions: Grid-based algorithms for mining spatial epidemiological data provide advantages in terms of computational complexity thus improving the speed of computations. We believe that these methods and this software tool (FGBASE) will lower the computational barriers to entry for those performing epidemiological research.",10.1186/1476-072X-13-46

+1971,Article,Balancing on a tightrope: Managing the boundaries of a firm-sponsored OSS community and its impact on innovation and absorptive capacity,"Realizing the innovation potential of OSS communities, firms now create or sponsor their own open source software (OSS) communities, generally as part of an open innovation strategy. However, maximizing the innovation capability of a sponsored OSS community is a challenging task since firms cannot rely on traditional hierarchical authority to control community members. Furthermore, a firm's efforts to manage its sponsored community may also impact the firm's absorptive capacity, or its ability to effectively absorb and leverage the valuable knowledge created by the community. Thus, the purpose of this article is to investigate two research questions: 1) How does the boundary management of a firm-sponsored OSS community impact the community's innovation capacity? and 2) How does the boundary management of a firm-sponsored OSS community impact the firm's absorptive capacity? Using the results from our qualitative analysis of eZ Systems and its successfully sponsored OSS community - eZ Publish we develop a theoretical model depicting how the boundary management of a firm-sponsored OSS community influences both the community's innovation capacity and the absorptive capacity of the firm. In addition, the results of our study highlight the central importance of an integrative IT platform in boundary management activities. (C) 2014 Elsevier Ltd.

Voxelized anatomical models are used in numerous applications including the computation of specific absorption rates associated with cell phone transmission energies, radiation therapy, and electromagnetic dosimetry simulation. Other applications range from the study of ergonomics to the design of clothing. Typically, the anatomical pose of a voxelized model is limited by the imaging device used to acquire the source anatomical data; however, absorption of emitted energies and the fit of clothes will change based on anatomic pose. Bender provides an intuitive, workflow-based user-interface to an extensible framework for changing the pose of anatomic models. Bender is implemented as a customized version of 3D Slicer, an image analysis and visualization framework that is widely used in the medical computing research community. The currently available repositioning methods in Bender are based on computer-graphics techniques for rigging, skinning, and resampling voxelized anatomical models. In this paper we present the software and compare two resampling methods: a novel extension to dual quaternions and finite element modeling (FEM) techniques. We show that FEM can be used to quickly and effectively resample repositioned anatomic models.",NA
+1974,Article,Beyond free software: An exploration of the business value of strategic open source,"The phenomenon of open source software (OSS) has been well studied from the software development perspective, but it has received much less attention from the perspective of business value. Nevertheless, OSS, when viewed as a value creation process rather than `free' software, provides businesses with value through access to knowledge and innovation capacity resident in online communities. This conceptualisation, which we label `strategic open source' requires firms to rethink their strategy and processes as there is a shift in focus from ownership to openness and collaboration with external parties. Nonetheless, the emergence of OSS poses a puzzle for conceptions of organisational theory. Therefore, a theorising process is needed in order to develop a deeper understanding of how value is created and captured with OSS. Using a field study of eleven European firms, this paper explores the creation and capture of business value from strategic open source. The findings reveal that while decision makers look to open innovation initiatives like OSS for value creation and capture, there is still a desire to remain self reliant, resulting in collaborative design (of external innovations) rather than collaborative decision making with value network partners in relation to how such innovations would help create and capture value within firms.

Materials and Methods: b-TCP-collagen composite material was fabricated by mixing b-TCP granules having a particle size of 0.15 to 0.8 mm and 75\\% porosity, with bovine dermis-derived soluble collagen sponge. The dry weight ratio of b-TCP granules-to-collagen ratios was 4:1. Bio-Oss Collagen or the b-TCP-collagen composite was used to fill a 5.0 mm-diameter calvarial defect in rats. The defects were evaluated by histological and histomorphological analyses of decalcified histological sections with hematoxylin and eosin staining 6 and 10 weeks, respectively, after surgery. Results: The defect implanted with the b-TCP composite contained immature bone structures with dense connective tissue in contrast to the abundant fibrous tissue, but no trabecular structure was observed within the defect implanted with Bio-Oss Collagen at 6 weeks postoperatively. Eventually, the defect filled with the b-TCP composite was covered with dense, continuous, mature bone tissue with complete replacement of the graft material. However, in defects filled with Bio-Oss Collagen, only dense connective tissue, containing limited amounts of immature trabecular bone and abundant remnant Bio-Oss particles, was observed. Histomorphological analysis revealed that the b-TCP composite caused greater tissue augmentation with a larger volume of bone tissue observed in the defect and greater bioabsorption of remnant material than Bio-Oss Collagen. Conclusion: These results indicated that the b-TCP composite has greater osteoconductivity and better biodegradation properties than Bio-Oss Collagen; these properties of the b-TCP-collagen composite complimented bone formation and remodeling.",10.1111/j.1708-8208.2012.00467.x

Results from a meta-analysis of all clinical trials (up to 2011) indicated a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. Our objective of this study is to build a virtual breast phantom lab in the public domain that can be used for rigorous imaging testing of this kind. Main thrust of this work is to streamline biomedical ultrasound simulations in conjunction with anatomically complex (software) phantoms by leveraging existing open source software packages including K-wave or Field II (acoustic simulation), VTK (data visualization and processing), FEBio (biomechanical deformation) and Tetgen (mesh generation). The integration of these four open source packages was based on a simple message-passing scheme to facilitate its use among imaging scientists. In this study, we demonstrated that a complex and heterogeneous (virtual) breast phantom can be derived from medical imaging data, i.e. publically available Visible Human Project data through US National Institutes of Health. Three volumes of interest were selected from the proposed virtual breast phantom to perform acoustic simulations using a virtual linear array transducer (6MHz and 80\\% bandwidth). Our initial results showed that simulated B-mode images accurately represented the underlying complex but known medium. In order to demonstrate applications in elastography, the virtual breast phantom was also deformed using finite element simulations. The resultant simulated strain image depicted complex patterns that were normally seen in clinical data. In conclusion, the proposed virtual software infrastructure can perform sophisticated ultrasound simulations in conjunction with complex and heterogeneous media. It is our intent that, in the future, the proposed virtual software infrastructure will be available to the research community for use in creation complex imaging benchmark tests for algorithm testing and validation. Furthermore, the proposed virtual platform can also be tailored to meet specific research needs by potential users themselves in an open science fashion.

+1984,InProceedings,Challenges and implications of verifiable builds for security-critical open-source software,"The majority of computer users download compiled software and run it directly on their machine. Apparently, this is also true for open-sourced software -- most users would not compile the available source, and implicitly trust that the available binaries have been compiled from the published source code (i.e., no backdoor has been inserted in the binary). To verify that the official binaries indeed correspond to the released source, one can compile the source of a given application, and then compare the locally generated binaries with the developer-provided official ones. However, such simple verification is non-trivial to achieve in practice, as modern compilers, and more generally, toolchains used in software packaging, have not been designed with verifiability in mind. Rather, the output of compilers is often dependent on parameters that can be strongly tied to the building environment. In this paper, we analyze a widely-used encryption tool, TrueCrypt, to verify its official binary with the corresponding source. We first manually replicate a close match to the official binaries of sixteen most recent versions of TrueCrypt for Windows up to v7.1a, and then explain the remaining differences that can solely be attributed to non-determinism in the build process. Our analysis provides the missing guarantee on official binaries that they are indeed backdoor-free, and makes audits on TrueCrypt's source code more meaningful. Also, we uncover several sources of non-determinism in TrueCrypt's compilation process; these findings may help create future verifiable build processes.",10.1145/2664243.2664288

CoCoTools both interfaces with the CoCoMac database, which houses a vast amount of annotated tracer results from 100 years (1905-2005) of neuroanatomical research, and implements coordinate-free registration algorithms, which allow studies that use different parcellations of the brain to be translated into a single graph. We show that using CoCoTools to translate all of the data stored in CoCoMac produces graphs with properties consistent with what is known about global brain organization. Moreover, in addition to describing CoCoTools' processing pipeline, we provide worked examples, tutorials, links to on-line documentation, and detailed appendices to aid scientists interested in using CoCoTools to gather and analyze CoCoMac data.",10.1162/jocn\\_a\\_00498

This tool is an unwritten standard not only for many school systems, but also for many state institutions in the Czech Republic, which make available statistical data in the form of programs SPSS.

Currently, there are two tools that could replace the proprietary software. These are programs SOFA (http:// www. sofastatistics. com) and PSPP (http:// www. gnu. org/ software/ pspp/), which are free and available under a license that allows these programs to install and use not only in academia, but also for possible future commercial use of students in this software will learn.

+1988,Article,Comparative evaluation of open source software for mapping between metabolite identifiers in metabolic network reconstructions: application to Recon 2,"Background: An important step in the reconstruction of a metabolic network is annotation of metabolites. Metabolites are generally annotated with various database or structure based identifiers. Metabolite annotations in metabolic reconstructions may be incorrect or incomplete and thus need to be updated prior to their use. Genome-scale metabolic reconstructions generally include hundreds of metabolites. Manually updating annotations is therefore highly laborious. This prompted us to look for open-source software applications that could facilitate automatic updating of annotations by mapping between available metabolite identifiers. We identified three applications developed for the metabolomics and chemical informatics communities as potential solutions. The applications were MetMask, the Chemical Translation System, and UniChem. The first implements a ``metabolite masking{''} strategy for mapping between identifiers whereas the latter two implement different versions of an InChI based strategy. Here we evaluated the suitability of these applications for the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We applied the best suited application to updating identifiers in Recon 2, the latest reconstruction of human metabolism. Results: All three applications enabled partially automatic updating of metabolite identifiers, but significant manual effort was still required to fully update identifiers. We were able to reduce this manual effort by searching for new identifiers using multiple types of information about metabolites. When multiple types of information were combined, the Chemical Translation System enabled us to update over 3,500 metabolite identifiers in Recon 2. All but approximately 200 identifiers were updated automatically. Conclusions: We found that an InChI based application such as the Chemical Translation System was better suited to the task of mapping between metabolite identifiers in genome-scale metabolic reconstructions. We identified several features, however, that could be added to such an application in order to tailor it to this task.",10.1186/1758-2946-6-2

Including function points and its variants, there are several size measures and corresponding measurement methods that can be used for effort estimation. However, in most of the projects, there is limited amount of information available in the early stages and significant effort is spent for size measurement and effort estimation with such methods. This paper analyzes the correlation between the size metrics of conceptual model of the problem domain and the resulting software. For this purpose, we consider open source project management and game software. We apply linear regression and cross validation techniques to investigate the relation between the sizes of problem domain (i.e., conceptual) and solution domain (i.e., design) models. The results reveal a high correlation between the number of conceptual classes in the problem domain model and the number of software classes constituting the corresponding software. The results suggest that it is possible to use problem domain descriptions in the early stages of software development projects to make plausible predictions for the size of the software.",10.1109/SEAA.2014.11

We show that, contrary to standard predictions, additional contribution to the public good by the government or a new market entrant can lead to higher investments of all incumbent firms, that is, a crowding-in effect. This result occurs if the investment cost function is superadditive. We find that government contribution leads to larger crowding-in effects than subsidizing market entry if the price elasticity of demand with respect to the private good is large relative to the one with respect to the public good.

The quantification of tumor heterogeneity with molecular images, by analyzing the local or global variation in the spatial arrangements of pixel intensity with texture analysis, possesses a great clinical potential for treatment planning and prognosis. To address the lack of available software for computing the tumor heterogeneity on the public domain, we develop a software package, namely, Chang-Gung Image Texture Analysis (CGITA) toolbox, and provide it to the research community as a free, open-source project. Methods. With a user-friendly graphical interface, CGITA provides users with an easy way to compute more than seventy heterogeneity indices. To test and demonstrate the usefulness of CGITA, we used a small cohort of eighteen locally advanced oral cavity (ORC) cancer patients treated with definitive radiotherapies. Results. In our case study of ORC data, we found that more than ten of the current implemented heterogeneity indices outperformed SUVmean for outcome prediction in the ROC analysis with a higher area under curve (AUC). Heterogeneity indices provide a better area under the curve up to 0.9 than the SUVmean and TLG (0.6 and 0.52, resp.). Conclusions.

In order to develop and evolve high quality OSS, projects are always in search of new committers. OSS projects often promote strong developers to become committers. When existing committers find strong developers, they propose their promotion to a committer role. Delaying the committer-promotion might lead to strong developers departing from an OSS project and the project losing them. However early committer-promotion comes with its own slew of risks as well (e.g., the promotion of inexperienced developers). Hence, committer-promotion decisions are critical for the quality and successful evolution of OSS projects. In this paper, we examine the committer-promotion phenomena for two OSS projects (Eclipse and Firefox). We find that the amount of activities by future committers was higher than the amount of activities by developers who did not become committers). We also find that some developers are promoted to a committer role very rapidly (within a few month) while some of developers take over one year to become a committer.

While prior research has explored the communal nature of open source software development among individual users, little research has explored whether these sharing concepts are also present in organizational use of open source software products. This study uses a theory integration approach to develop some initial insight into the differences between users and non-users of open source software. This study observed three groups of factors from six case studies of information sharing in the context of organizational open source software use. These factors were integrated with prior research in order to understand the physical and managerial barriers to, and enablers of, open source. The study proposes that open source users have more extensive knowledge sharing and teamwork practices in place, and are more tolerant of risk. The study also argues that open source users depended less on external technology support services but have more extensive information technology ( IT) support structures.

+1022,InProceedings,FOSS IMPLEMENTATION OF AN EDUCATIONAL VIRTUAL OFFICE SUITE,"Academic institutions and research organisations are fast becoming very corporate in the design and setup of the workspace. There is an ever-present need for readily available information and sophisticated means of communication. As a result, information and communication technologies are being deployed for application in various fields of endeavour some of which include virtual offices. A virtual office is essentially a simulated corporate environment that gives subscribers access to collaborative work related features, which act as a means of improving the way work is carried out in an organisation. Several organisations opt for the software services rendered by virtual offices because of their cost effectiveness and tendency to boost the collective productivity of these organisations. For reasons as such, the existence of virtual office software suites have become rampant, but the availability of its services are at a cost. This paper reports the design and implementation of an Educational Virtual Office using Free and Open-Source Software (FOSS) to relieve corporate organisations of the costly burdens of existing proprietary virtual office software. Tools used in achieving this feat are Drupal Web Content Management System (WCMS), readily available FOSS and a couple of other freeware, intelligently integrated to form a composite suite. The developed educational virtual office suite was deployed in the Department of Electrical and Information Engineering of Covenant University. A usability (user satisfaction) test was conducted. Analysis of the test results showed that questions related to user satisfaction scored more ``Strongly Agree{''} and ``Agree{''} points than ``Disagree{''} and ``Strongly Disagree{''}. This is a pointer to the fact that features such as the GUI of the web application and its navigation proved to have little or no challenges as at when the tests were carried out. Deployment of the developed educational virtual office suite has the significant advantage of low cost in comparison with proprietary virtual office suites with similar functionality. The fact that the suite was developed entirely using FOSS gives it all the attendant advantages that accrue from the employment of same from the system design bottom-Up.

The finite-size parameters make a quantitative distinction between the in-directed and out-directed networks. For the out-degree distribution, the initial condition for a dynamic evolution corresponds to the limiting count of the most heavily linked nodes that the out-directed network can finally have. The number of nodes contributing out-directed links grows with every generation of software release, but this growth ultimately saturates toward a terminal value, due to the finiteness of semantic possibilities in the network.",10.25088/ComplexSystems.23.1.71

Shifting focus can have impact on the software quality and productivity, and is thus an important topic of investigation. In this paper, we study focus shifting patterns (FSPs) of developers by comparing trace data from a dozen open source software (OSS) projects of their longitudinal commit activities and file dependencies from the projects call graphs. Using information theoretic measures of network structure, we find that fairly complex focus-shifting patterns emerge, and FSPs in the same project are more similar to each other. We show that developers tend to shift focus along with, rather than away from, software dependency links described by the call graphs. This tendency becomes weaker as either the interval between successive commits, or the organizational distance between committed files (i.e. directory distance), gets larger. Interestingly, this tendency appears stronger with more productive developers. We hope our study will initiate interest in further understanding of FSPs, which can ultimately help to (1) improve current recommender systems to predict the next focus of developers, and (2) provide insight into better call graph design, so as to facilitate developers' work.",10.1145/2635868.2635914

These tools are extending and changing the toolset used for FLOSS development, and redefining what a software forge looks like. The main contributions of this paper are to describe each of these tools, to identify the data and artifacts available for mining from these tools, and to outline some of the ways researchers can use these artifacts to continue to understand how FLOSS is made.",10.1109/HICSS.2014.405

The current situation of the majority of dairy farms in Galicia, with production costs steadily rising and stagnant incomes are critical for the future. Currently, due to the price paid by industry to producers they are in an extreme situation with similar production costs and incomes. The absence of specific tools that enable them to optimize their cost structure further aggravates the situation. Previous studies by this research group considered that the cost structure of Galician dairy farms, they made marginal investments in technical or consultancy services, management and administration. To improve this situation, the specific tools based on open source is proposed as an appropriate efficiency management tool for this business, unwilling to invest in individual management and used to follow the strategies dictated from the government. In this context there places the base of the investigation proposed as significant form of contributing solutions to the problems of the lacteal sector of Galicia.",NA

Being software development a process where learning and collaboration is of major importance, FLOSS projects have in common many characteristics with MOOCs. This is because many FLOSS projects (such as Linux, Apache, GNOME or KDE, among others) are massive, they are open to anyone to participate, and are driven mainly by telematic means. We therefore present the research literature that has studied FLOSS projects from points of view that are close to learning and discuss how the FLOSS community has approached many of the issues related to acquiring knowledge and skills over the Internet and compare them to how currently MOOCs, both xMOOCs and cMOOCs, address these situations.",NA
+1035,Article,FreeContact: fast and free software for protein contact prediction from residue co-evolution,"Background: 20 years of improved technology and growing sequences now renders residue-residue contact constraints in large protein families through correlated mutations accurate enough to drive de novo predictions of protein three-dimensional structure. The method EVfold broke new ground using mean-field Direct Coupling Analysis (EVfold-mfDCA); the method PSICOV applied a related concept by estimating a sparse inverse covariance matrix. Both methods (EVfold-mfDCA and PSICOV) are publicly available, but both require too much CPU time for interactive applications. On top, EVfold-mfDCA depends on proprietary software. Results: Here, we present FreeContact, a fast, open source implementation of EVfold-mfDCA and PSICOV. On a test set of 140 proteins, FreeContact was almost eight times faster than PSICOV without decreasing prediction performance. The EVfold-mfDCA implementation of FreeContact was over 220 times faster than PSICOV with negligible performance decrease. EVfold-mfDCA was unavailable for testing due to its dependency on proprietary software. FreeContact is implemented as the free C++ library ``libfreecontact{''}, complete with command line tool ``freecontact{''}, as well as Perl and Python modules. All components are available as Debian packages. FreeContact supports the BioXSD format for interoperability. Conclusions: FreeContact provides the opportunity to compute reliable contact predictions in any environment (desktop or cloud).",10.1186/1471-2105-15-85
+1036,Article,From open-source software to Wikipedia: `Backgrounding' trust by collective monitoring and reputation tracking,"Open-content communities that focus on co-creation without requirements for entry have to face the issue of institutional trust in contributors. This research investigates the various ways in which these communities manage this issue. It is shown that communities of open-source software-continue to-rely mainly on hierarchy (reserving write-access for higher echelons), which substitutes (the need for) trust. Encyclopedic communities, though, largely avoid this solution. In the particular case of Wikipedia, which is confronted with persistent vandalism, another arrangement has been pioneered instead. Trust (i.e. full write-access) is `backgrounded' by means of a permanent mobilization of Wikipedians to monitor incoming edits. Computational approaches have been developed for the purpose, yielding both sophisticated monitoring tools that are used by human patrollers, and bots that operate autonomously. Measures of reputation are also under investigation within Wikipedia; their incorporation in monitoring efforts, as an indicator of the trustworthiness of editors, is envisaged. These collective monitoring efforts are interpreted as focusing on avoiding possible damage being inflicted on Wikipedian spaces, thereby being allowed to keep the discretionary powers of editing intact for all users. Further, the essential differences between backgrounding and substituting trust are elaborated. Finally it is argued that the Wikipedian monitoring of new edits, especially by its heavy reliance on computational tools, raises a number of moral questions that need to be answered urgently.",10.1007/s10676-014-9342-9

GitHub portal is an online social network that supports development of software by virtual teams of programmers. Since there is no central mechanism that governs the process of team formation, it is interesting to investigate if there are any significant correlations between project quality and the characteristics of the team members. However, for such analysis to be possible, we need good metrics of a project quality. This paper develops two such metrics, first one reflecting project's popularity, and the second one - the quality of support offered by team members to users. The first metric is based on the number of `stars' a project is given by other GitHub members, the second is obtained using survival analysis techniques applied to issues reported on the project by its users. After developing the metrics we have gathered characteristics of several GitHub projects and analyzed their influence on the project quality using statistical regression techniques.",NA

The growth rate is unprecedented. The software industry is inclining towards adopting OSS despite concerns about the quality. Defect management has been a key issue in OSS. Software whether it is close or open source uses energy. Green computing argued that environmental conditions are getting worst and use of power consumptions should be minimized to protect the earth. A lot of work has been reported in the area of green hardware but very little work has been reported in making software green. The main objective this work is to increase understanding of green software development. In this study, we empirically investigate that whether there is relationship between defect management in OSS and power consumption of OSS application. We used a dataset consist of 82 OSS projects to study the research model of this investigation. The results of this investigation show that software defect management in OSS play a significant role in managing power consumption of OSS applications.",NA
+1041,InProceedings,How social Q&A sites are changing knowledge sharing in open source software communities,"Historically, mailing lists have been the preferred means for coordinating development and user support activities. With the emergence and popularity growth of social Q&A sites such as the StackExchange network (e.g., StackOverflow), this is beginning to change. Such sites offer different socio-technical incentives to their participants than mailing lists do, e.g., rich web environments to store and manage content collaboratively, or a place to showcase their knowledge and expertise more vividly to peers or potential recruiters. A key difference between StackExchange and mailing lists is gamification, i.e., StackExchange participants compete to obtain reputation points and badges. In this paper, we use a case study of R (a widely-used tool for data analysis) to investigate how mailing list participation has evolved since the launch of StackExchange. Our main contribution is the assembly of a joint data set from the two sources, in which participants in both the texttt{r-help} mailing list and StackExchange are identifiable. This permits their activities to be linked across the two resources and also over time. With this data set we found that user support activities show a strong shift away from texttt{r-help}. In particular, mailing list experts are migrating to StackExchange, where their behaviour is different. First, participants active both on texttt{r-help} and on StackExchange are more active than those who focus exclusively on only one of the two. Second, they provide faster answers on StackExchange than on texttt{r-help}, suggesting they are motivated by the emph{gamified} environment. To our knowledge, our study is the first to directly chart the changes in behaviour of specific contributors as they migrate into gamified environments, and has important implications for knowledge management in software engineering.",10.1145/2531602.2531659

It is unclear whether these motivations have any actual impact on OSS project success. <u>Goal:</u> To identify how an OSS developer's reputation affects the outcome of his/her code review requests. <u>Method:</u> We conducted a social network analysis (SNA) of the code review data from eight popular OSS projects. Working on the assumption that core developers have better reputation than peripheral developers, we developed an approach, Core Identification using K-means (CIK) to divide the OSS developers into core and periphery groups based on six SNA centrality measures. We then compared the outcome of the code review process for members of the two groups. <u>Results:</u> The results suggest that the core developers receive quicker first feedback on their review request, complete the review process in shorter time, and are more likely to have their code changes accepted into the project codebase. Peripheral developers may have to wait 2 - 19 times (or 12 - 96 hours) longer than core developers for the review process of their code to complete. <u>Conclusion:</u> We recommend that projects allocate resources or create tool support to triage the code review requests to motivate prospective developers through quick feedback.",10.1145/2652524.2652544

However, this appears to be a necessary, but not a sufficient condition, as the well-being of FLOSS communities also relies on members behaving as ``good citizens,{''} to nurture and protect the community. This paper investigates the notion of FLOSS community citizenship behaviors in light of the organizational citizenship behaviors literature. Relying on 11 semi-structured interviews with FLOSS project leaders and community managers, the papers identifies key instances of citizenship behaviors along two dimensions: CCB-I (community citizenship behaviors oriented towards the benefits of other individuals), and CCB-P (community citizenship behaviors oriented towards the benefits of the project and its community).",10.1109/HICSS.2014.406

We present a corpus of online communication messages randomly sampled from newsgroups and bug trackers, manually annotated as requests or non-requests. We identify several linguistically shallow, content-based heuristics that correlate with the classification and investigate the extent to which they can serve as independent classification criteria. Then, we train machine-learning classifiers on these heuristics. We experiment with a wide range of settings, such as different learners, excluding some heuristics and adding unigram features of various parts-of-speech and frequency. We conclude that some heuristics can perform well, while their accuracy can be improved further using machine learning, at the cost of obtaining manual annotations.",NA
+1052,Article,MEIGO: an open-source software suite based on metaheuristics for global optimization in systems biology and bioinformatics,"Background: Optimization is the key to solving many problems in computational biology. Global optimization methods, which provide a robust methodology, and metaheuristics in particular have proven to be the most efficient methods for many applications. Despite their utility, there is a limited availability of metaheuristic tools. Results: We present MEIGO, an R and Matlab optimization toolbox (also available in Python via a wrapper of the R version), that implements metaheuristics capable of solving diverse problems arising in systems biology and bioinformatics. The toolbox includes the enhanced scatter search method (eSS) for continuous nonlinear programming (cNLP) and mixed-integer programming (MINLP) problems, and variable neighborhood search (VNS) for Integer Programming (IP) problems. Additionally, the R version includes BayesFit for parameter estimation by Bayesian inference. The eSS and VNS methods can be run on a single-thread or in parallel using a cooperative strategy. The code is supplied under GPLv3 and is available at http://www.iim.csic.es/similar to gingproc/meigo.html. Documentation and examples are included. The R package has been submitted to BioConductor. We evaluate MEIGO against optimization benchmarks, and illustrate its applicability to a series of case studies in bioinformatics and systems biology where it outperforms other state-of-the-art methods.

Currently, there exists no working operationalization available that can be used to determine the health of open source ecosystems. Health is typically looked at from a project scope, not from an ecosystem scope. Objectives: With such an operationalization, stakeholders can make better decisions on whether to invest in an ecosystem: developers can select the healthiest ecosystem to join, keystone organizers can establish which governance techniques are effective, and end-users can select ecosystems that are robust, will live long, and prosper. Method: Design research is used to create the health operationalization. The evaluation step is done using four ecosystem health projects from literature. Results: The Open Source Ecosystem Health Operationalization is provided, which establishes the health of a complete software ecosystem, using the data from collections of open source projects that belong to the ecosystem. Conclusion: The groundwork is done, by providing a summary of research challenges, for more research in ecosystem health. With the operationalization in hand, researchers no longer need to start from scratch when researching open source ecosystems' health. (C) 2014 Elsevier B.V.

Yet relational event data are typically aggregated and dichotomized to derive networks that can be analyzed with specialized statistical methods. Transforming sequences of relational events into binary network ties entails two main limitations: the loss of information about the order and number of events that compose each tie and the inability to account for compositional changes in the set of actors and/or recipients. In this article, we introduce a newly developed class of statistical models that enables researchers to exploit the full information contained in sequences of relational events. We propose an extension of the models to cater for sequences of relational events linking different sets of actors. We illustrate the empirical application of relational event models in the context of a free/open source software project with the aim to explain the level of effort produced by contributors to the project. We offer guidance in the interpretation of model parameters by characterizing the social processes underlying organizational problem solving.

However empirical studies on modularity of OSS systems have resulted in confusing results. To account for underlying mechanisms of those confusing results, we systematically examine widely studied OSS projects. Based on our systematic review on technical and organizational structures, we suggest that organizational circumstances of OSS production are at least in a continuum of tightly-coupled and loosely- coupled organizational circumstances of production in which both geographically distributed volunteers and paid developers with organizational ties work together (albeit separately over time). Furthermore, organizational circumstances of OSS production appear to be dynamic, as firms move in and out of OSS production communities over time. In essence we argue that the reason for the confusing empirical results was a persistent assumption that organizational circumstances of OSS production are static or unitary; rather what matters is the organizational circumstances of production in any episode of contribution. This research agenda paper proposes future inquiries to develop a comprehensive picture of ecological shift in different levels of system modularity and organizational circumstances of OSS production over time and through episodes.",NA

To successfully run IT business, it is important to properly understand the OSS development status. Having a proper understanding of development status is necessary to evaluate and predict the product quality. However, the OSS development status is not easy to understand, because it is often concurrently developed by many distributed contributors, and its developmental structure is complicated. To aid the understanding of the development status, there is an approach that models the trend of source code change events (evolution) with a growth curve. Although an application of growth curves seems to be a promising approach, there has been a big issue that a single growth curve is often unsuitable for modeling the whole evolution because of its complex evolutionary behavior. This paper proposes a multistage model that divides the whole development period into some stages, and applies a different growth curve to a different stage.

Patients and methods. Compared with the ISG/OS-1 study (cumulative doses: ADM 420 mg/m(2), MTX 120 g/m(2), CDP 600 mg/m(2), IFO 30 g/m(2)), the ISG/OS-Oss study reduced the number of MTX cycles from 10 to 5 (cumulative MTX dose: 60 g/m(2)) in order to diminish treatment duration and toxicity. Results. From January 2007 to June 2011, 171 patients (median age 16 years, 60\\% males) were registered. The limb salvage rate was 94\\% and the good pathologic response rate 51\\% (these figures were 92\\% and 48\\%, respectively, in the ISG/OS-1 study). At a median follow-up of 39 months (range, 4-80), the 5-year overall survival rate was 80\\% (95\\% CI, 73\\%-87\\%) and the event-free survival was 50\\% (95\\% CI, 39\\%-59\\%).

This study confirms that in nonmetastatic osteosarcoma of the extremity, conservative surgery in more than 90\\% and a good pathologic response rate of 50\\% can be expected with primary chemotherapy based on the MAP regimen. The response and resection rates in the ISG/OS-Oss study are in the same range as those of the previous study, whereas the event-free survival is lower than that previously achieved.

+1078,InProceedings,Older Adults and Free/Open Source Software: A Diary Study of First-Time Contributors,"The global population is aging rapidly, and older adults are becoming increasingly technically savvy. This paper explores ways to engage these individuals to contribute to free/open source software (FOSS) projects. We conducted a pilot diary study to explore motivations, barriers, and the contribution processes of first-time contributors in a real time, qualitative manner. In addition, we measured their self-efficacy before and after their participation. We found that what drove participants were intrinsic motivations, altruism, and internal values, which differed from previous work with older adults and with the general FOSS population. We also found that self-efficacy did not change significantly, even when participants encountered significant barriers or setbacks. The top 3 barriers were lack of communication, installation issues, and documentation issues. We found that asking for and receiving help, and avoiding difficult development environments were more likely to lead to success. To verify these results, we encourage a future large-scale diary study that involves multiple demographics. Given our pilot study, we recommend that future outreach efforts involving older adults focus on how to effectively communicate and build community amongst older contributors.",10.1145/2641580.2641589

We interviewed 11 older FOSS contributors and 6 FOSS community leaders (of any age). This formative study reports on 4 key findings from those interviews: 1) motivations of older contributors, 2) benefits and challenges to contribution, 3) older adults' views on discrimination in FOSS, and 4) ways in which older adults enrich FOSS communities. We found that older adults' contributions are driven by intrinsic motivation, altruism, and community identification. In older adults' most recent contributions, we found that there were more social than technical challenges to participation. Interestingly, the majority of older adults claimed to have witnessed discrimination towards others in FOSS, especially against non-native English speakers and women. This stands in contrast to what the general male FOSS developer population reports. Participants identified 10 ways that older adults add value to FOSS communities. We conclude with guidelines for onboarding older adults.",NA

Once software complexity is one of the most important attributes to determine software maintainability, controlling its level in the system evolution process makes the software easier to maintain, reducing the maintainability costs. Otherwise, uncontrolled complexity makes the maintenance and enhancement process lengthy, more costly and some times it can contribute to the system abandonment. This work investigates the evolution of complexity in discontinued FLOSS projects. After several analyses, the results showed that inactive FLOSS projects do not seem to be able to keep up with the extra work required to control the systems complexity, presenting a different behaviour of the successful active FLOSS projects.",NA

The ITS model provides probabilistic predictions of skin sensitization potency based on in silico and in vitro information as well as skin penetration characteristics from a published bioavailability model (Kasting et al., 2008). The structure of the Bayesian network was designed to be consistent with the adverse outcome pathway published by the OECD (Jaworska et al., 2011, 2013). In this paper, the previously published data set (Jaworska et al., 2013) is improved by two data corrections and a modified application of the Kasting model. The new data set implemented in the original commercial software package and the new R version produced consistent results.

In this approach, scaffolds provide a temporary mechanical and vascular support for tissue regeneration while tissue in-growth is being formed. The design of optimized scaffolds for tissue engineering is a key topic of research, as the complex macro-and micro-architectures required for a scaffold depends on the mechanical properties, and the physical and molecular stimulations of the surrounding tissue at the defect site. One way to achieve such designs is to create a library of unit cells ( the scaffold is assumed to be a repeating, tessellating unit structure), which can be assembled through specific computational tools proposed by several authors. In this research work, an open source software tool for the design of scaffolds is presented. (C) 2014 The Authors. Published by Elsevier Ltd.",10.1016/j.protcy.2014.10.176

A variety of bioreactors are commercially available, often including sophisticated software to enhance the functionality of the bioreactor. However, experiments that the bioreactor hardware can support, but that were not envisioned during the software design cannot be performed without developing custom software. In addition, support for third party or custom designed auxiliary hardware is often sparse or absent. This work presents flexible open source freeware for the control of bioreactors of the Bioflo product family. The functionality of the software includes setpoint control, data logging, and protocol execution. Auxiliary hardware can be easily integrated and controlled through an integrated plugin interface without altering existing software. Simple experimental protocols can be entered as a CSV scripting file, and a Python-based protocol execution model is included for more demanding conditional experimental control. The software was designed to be a more flexible and free open source alternative to the commercially available solution. The source code and various auxiliary hardware plugins are publicly available for download from https://github.com/LibourelLab/BiofloSoftware.

Second, in the spirit of the open innovation research, we concentrate on the mechanisms that OSS SMEs put in place to get access to the external resources of the OSS community. Econometric evidence on 100 European OSS SMEs shows that firm size is negatively associated to within-industry diversification, while OSS SMEs that have contributed to a larger number of OSS projects have a more diversified portfolio of software products. Furthermore, we provide preliminary evidence that the practice of authorizing firm programmers to contribute autonomously to OSS projects of their own choice during working hours may be positively associated to within-industry diversification only if OSS SMEs possess adequate internal technological resources.

We report on the software development practices used by creators of algorithm visualizations, based on data that can be inferred from a catalog of over 600 algorithm visualizations. Since nearly all are free for use and many provide source code, they might be construed as being open source software. Yet many AV developers do not appear to have used open source best practices. We discuss how such development practices might be employed by the algorithm visualization community, and how they might lead to improved algorithm visualizations in the future. We conclude with a discussion of OpenDSA, an open-source project that builds on earlier progress in the field of algorithm visualization and hopes to use open-source procedures to gain users and contributors.

+1090,Article,Open source software subsidies and network compatibility in a mixed duopoly,"Open source software (OSS) generally offers a high-quality alternative to proprietary software (e.g. Linux, Apache, Android, etc.) for many applications. Although OSS is usually free of charge, its diffusion remains limited, Should government intervene to promote the diffusion of OSS, and offer potential adopters some learning or financial support? This paper examines whether public subsidies for OSS are socially desirable. and how the extent of compatibility between OSS and proprietary software (PS) might influence the optimal subsidy offered. We consider a mixed duopoly model in which a PS company competes with an OSS community. Users are heterogeneous in their ability to use OSS, and their utility depends on the number of users who adopt the same or compatible software (existence of network externalities). Four situations are distinguished: full compatibility between OSS and PS, full incompatibility, and one-way compatibility (either only OSS or PS is compatible). We show that if the government places more weight on consumer surplus. public subsidies are welfare-enhancing. But the optimal subsidy level is larger with full compatibility and PS compatibility than full incompatibility and OSS compatibility. These results suggest that government policy towards OSS should be conditional on the degree of compatibility between PS and OSS.",NA

It faces a `staff scheduling' problem. The team consists of 16 Cardiologists to ensure daytime and nighttime guards, a nighttime on-call service, on-call service for full day on weekends and public holidays and a 24h hemodynamic on-call. Special situations and exceptions are taken into account. An original software was developed in Java to input data, generate the mathematical model and read back the solution, relying on a open SQL database. The solution is obtained by GUSEK, an open tool to the linear programming solver GLPK minimizing the sum of the deviations from individual quotas. The system generates the shifts monthly. Typical computation time is few minutes to ensure that a solution exists and few hours to obtain a highly optimized solution. The system is in use for 22 months. It provides equal assignment of Cardiologists to each type of shift with uniform like distribution, avoiding immediate repetition of the same shift.

Our results showed that RCF-OSS performance changes significantly between 5 and 7 years of age. While most 5-year-olds used a local approach when copying the Rey-Osterrieth Complex Figure (ROCF), 7-year-olds increasingly adopted a global approach. RCF-OSS performance correlated significantly, but moderately with measures of ROCF accuracy, executive functioning (fluency, working memory, reasoning), and non-executive functioning (visual-motor integration, visual attention, processing speed, numeracy). These findings seem to indicate that RCF-OSS performance reflects a range of cognitive skills at 5 to 7 years of age, including aspects of executive and non-executive functioning.",10.1080/13854046.2014.939228
+1094,Article,OxMaR: Open Source Free Software for Online Minimization and Randomization for Clinical Trials,"Minimization is a valuable method for allocating participants between the control and experimental arms of clinical studies. The use of minimization reduces differences that might arise by chance between the study arms in the distribution of patient characteristics such as gender, ethnicity and age. However, unlike randomization, minimization requires real time assessment of each new participant with respect to the preceding distribution of relevant participant characteristics within the different arms of the study. For multi-site studies, this necessitates centralized computational analysis that is shared between all study locations. Unfortunately, there is no suitable freely available open source or free software that can be used for this purpose. OxMaR was developed to enable researchers in any location to use minimization for patient allocation and to access the minimization algorithm using any device that can connect to the internet such as a desktop computer, tablet or mobile phone. The software is complete in itself and requires no special packages or libraries to be installed. It is simple to set up and run over the internet using online facilities which are very low cost or even free to the user. Importantly, it provides real time information on allocation to the study lead or administrator and generates real time distributed backups with each allocation. OxMaR can readily be modified and customised and can also be used for standard randomization. It has been extensively tested and has been used successfully in a low budget multi-centre study. Hitherto, the logistical difficulties involved in minimization have precluded its use in many small studies and this software should allow more widespread use of minimization which should lead to studies with better matched control and experimental arms. OxMaR should be particularly valuable in low resource settings.",10.1371/journal.pone.0110761

POLYS is written in portable ANSI C and is now released under an open source license. Using this software, complex branched carbohydrate structures and polysaccharides can be constructed from their primary structure and the relevant monosaccharides stored in database containing information on optimized glycosidic linkage geometries. The constructed three-dimensional structures are described as Cartesian coordinate files which can be used as input to other molecular modeling software. The new version of POLYS includes a large database of monosaccharides and a helical generator to build and optimize regular single helix or double helix structures. To demonstrate the efficiency of POLYS to build carbohydrate structures, four examples of increasing complexity are presented in the manuscript, from simple alpha glucans over complex starch fragments and the double helical structure of amylopectin to the mega-oligosaccharide RhamnoGalacturonan II.

+1099,Article,Peculiarities of Bone Regeneration in Cases of Bio-Oss® and Autological Bone Graft Use - Experimental Study,"Background. Bone tissue regeneration remains one of the most important issues of maxillofacial surgery. Restoration of the native structure of bone after osteoplasty is directly related to the process of revascularization, because the growing of blood vessels into the graft is a precondition for transport of osteogenic cells, growth factors necessary for further osteogenesis. Objectives. To determine the peculiarities of bone tissue regeneration after osteoplasty with BioOss (R) and compare it with autological bone graft. Material and Methods. Experimental study was conducted on 60 white rats (males, aged 6- 8 month, weight 270- 380 g). The area of dorsal surface of the shinbone was used for implantation. After opening access to the bone surface, one 2 mm-diameter defect was formed on each shinbone. One of those bone defects was filled with osteoplastic material and the opposite was healing under a blood clot. After that the wound in soft tissues was closed in layer by layer. The osteocalcin level in blood serum was determined by ELISA employing N-MID Osteocalcin (R) ELISA (IDS) test system(enzyme immunological test for the quantitative measurement of osteocalcin). The peculiarities of revascularization were studied by histologic method. Histologic specimen were stained using Schmorl technique (thionine with phenol trinitrate) and natural hematoxylin-eosin. Results. Mean values of osteocalcin concentration after BioOss implantation ranged from 2 +/- 0.06 ng/mL to 3.65 +/- 0.09 ng/mL; after autological bone graft transplant - from 1.88 +/- 0.09 ng/mLto 2.2 +/- 0.09 ng/mL. In the case of Bio-Oss use, the most active revascularization processes and the highest level of osteocalcin were registered on day 60. In the case of autological bone graft use, the quantity of blood vessels increased steadily and equally during the whole period of the experiment. Conclusions. According to the obtained results, the use of autological bone graft and Bio-Oss osteoplastic material increases bone formation and revascularization activity and improves the bone structure unlike when healing took place under the blood clot",NA
+1100,Article,"Peer Review on Open-Source Software Projects: Parameters, Statistical Models, and Theory","Peer review is seen as an important quality-assurance mechanism in both industrial development and the open-source software (OSS) community. The techniques for performing inspections have been well studied in industry; in OSS development, software peer reviews are not as well understood. To develop an empirical understanding of OSS peer review, we examine the review policies of 25 OSS projects and study the archival records of six large, mature, successful OSS projects. We extract a series of measures based on those used in traditional inspection experiments. We measure the frequency of review, the size of the contribution under review, the level of participation during review, the experience and expertise of the individuals involved in the review, the review interval, and the number of issues discussed during review. We create statistical models of the review efficiency, review interval, and effectiveness, the issues discussed during review, to determine which measures have the largest impact on review efficacy. We find that OSS peer reviews are conducted asynchronously by empowered experts who focus on changes that are in their area of expertise. Reviewers provide timely, regular feedback on small changes. The descriptive statistics clearly show that OSS review is drastically different from traditional inspection.",10.1145/2594458

PDLSCs and BMMSCs were obtained from the same canine donor. Twenty-four rats were randomly assigned to one of four experimental groups (n=6 each): group A (no-graft negative control), group B (Bio-Oss positive control), group C (BMMSC/Bio-Oss test group), and group D (PDLSC/Bio-Oss test group). Eight weeks post-transplantation, ectopic and in situ bone regeneration was evaluated by micro-computed tomography (mu-CT), histology, histomorphometry, and immunohistochemistry. The stem cell/Bio-Oss constructs were significantly superior to the controls in terms of their ability to promote osteogenesis (p<0.01), while the PDLSC/Bio-Oss construct tended to be superior to the BMMSC/Bio-Oss construct. Thus, engineered stem cell/Bio-Oss complexes can successfully reconstruct critical-size defects in rats, and PDLSCs and BMMSCs are both suitable as seed cells.",10.1177/0885328214521846
+1104,Article,Physicochemical characterization of InterOss® and Bio-Oss® anorganic bovine bone grafting material for oral surgery - A comparative study,"The anorganic bovine bone grafting materials have been widely used to fill bone defects in periodontal and maxillofacial surgery. The purpose of present study was to fully characterize our anorganic bone, InterOss (R), by physical and chemical methods and to compare it with another anorganic bone, Bio-Oss (R) that has been commercially distributed in dental bone graft substitute market since 1995. InterOss (R) anorganic bone had been successfully prepared by chemical treatment (NaOH and H2O2) and low temperature (350 degrees C) annealing process with an extremely low heating rate (<0.3 degrees C min(-1)). Commercially available Bio-Oss (R) anorganic bone was chosen for comparison. The physical and chemical analysis indicated that the pore structure, microstructure, phase structure, and chemical composition of InterOss (R) is substantially equivalent to that of Bio-Oss (R). The BET analysis also showed that the inner surface area of InterOss (R) is comparatively higher than that of Bio-Oss (R). Specially, the protein analysis showed that the content of residual protein of InterOss (R) is relatively lower than that of Bio-Oss (R). Based on an equivalency to Bio-Oss (R) in terms of physical and chemical characterization with both higher inner surface area and lower residual protein content, the InterOss (R) can be a promising candidate as dental bone grafting material in periodontal and maxillofacial surgery.

+1108,Article,Predicting Stability of Open-Source Software Systems Using Combination of Bayesian Classifiers,"The use of free and Open-Source Software (OSS) systems is gaining momentum. Organizations are also now adopting OSS, despite some reservations, particularly about the quality issues. Stability of software is one of the main features in software quality management that needs to be understood and accurately predicted. It deals with the impact resulting from software changes and argues that stable components lead to a cost-effective software evolution. Changes are most common phenomena present in OSS in comparison to proprietary software. This makes OSS system evolution a rich context to study and predict stability. Our objective in this work is to build stability prediction models that are not only accurate but also interpretable, that is, able to explain the link between the architectural aspects of a software component and its stability behavior in the context of OSS. Therefore, we propose a new approach based on classifiers combination capable of preserving prediction interpretability. Our approach is classifier-structure dependent. Therefore, we propose a particular solution for combining Bayesian classifiers in order to derive a more accurate composite classifier that preserves interpretability. This solution is implemented using a genetic algorithm and applied in the context of an OSS large-scale system, namely the standard Java API. The empirical results show that our approach outperforms state-of-the-art approaches from both machine learning and software engineering.",10.1145/2555596

In GitHub, developers are allowed to fork repositories and copy repositories without asking for permission, which make contribution to projects much easier than it has ever been. It is significant to predict the number of forks for open source software projects. The prediction can help GitHub to recommend popular projects, and guide developers to find projects which are likely to succeed and worthy of their contribution. In this paper, we use stepwise regression and design a model to predict the number of forks for open source software projects. Then we collect datasets of 1,000 repositories through GitHub's APIs. We use datasets of 700 repositories to compute the weight of attributes and realize the model. Then we use other 300 repositories to verify the prediction accuracy of our model. Advantages of our model include: (1) Some attributes used in our model are new. This is because GitHub is different from traditional open source software platforms and has some new features. These new features are used to build our model. (2) Our model uses project information within t month after its creation, and predicts the number of forks in the month T (t < T). It allows users to set the combination of time parameters and satisfy their own needs. (3) Our model predicts the exact number of forks, rather than the range of the number of forks (4) Experiments show that our model has high prediction accuracy. For example, we use project information with 3 months to prediction the number of forks in month 6 after its creation. The correlation coefficient is as high as 0.992, and the median number of absolute difference between prediction value and actual value is only 1.8. It shows that the predicted number of forks is very close to the actual number of forks. Our model also has high prediction accuracy when we set other time parameters.",10.1145/2627508.2627515
+1111,InProceedings,Preliminary Empirical Identification of Barriers Faced by Newcomers to Open Source Software Projects,"When newcomers try to join an open source soft-ware (OSS) project, they face many barriers that hinder their first contribution, leading in many cases to their dropping out. Many projects leverage the contribution of outsiders, and the sustainability of the project relies on retaining some of these new-comers. This research aims to identify the barriers that hinder newcomers' onboarding to OSS projects. Our method consisted of a qualitative study conducted with data obtained from four different sources: (i) systematic literature review, (ii) feedback from nine graduate and undergraduate students after they tried to join OSS projects, (iii) 24 responses to a questionnaire sent to 9 OSS projects, and (iv) semi-structured interviews with 36 sub-jects from 14 different projects, including newcomers and experi-enced members. The method to select the candidate papers in the systematic literature review was querying four digital libraries and backward snowballing. The data obtained from the practi-tioners from all three sources, and the primary studies obtained in the systematic review were analyzed using used procedures of Grounded Theory's open and axial coding. The analysis resulted in a conceptual model composed of 58 barriers, grouped into six different categories: cultural differences, newcomers' characteris-tics, reception issues, orientation, technical hurdles, and docu-mentation problems. We could observe recurrent barriers evi-denced in different data sources. We could notice that the onboarding process of a newcomer to an OSS can be a tough task. This research brings empirical support relying on data from different sources, organizes and discusses the existing common wisdom about barriers faced by newcomers to OSS projects, which deserve attention from researchers and OSS communities.",10.1109/SBES.2014.9
+1115,Article,QuBiLS-MIDAS: A Parallel Free-Software for Molecular Descriptors Computation Based on Multilinear Algebraic Maps,"The present report introduces the QuBiLS-MIDAS software belonging to the ToMoCoMD-CARDD suite for the calculation of three-dimensional molecular descriptors (MDs) based on the two-linear (bilinear), three-linear, and four-linear (multilinear or N-linear) algebraic forms. Thus, it is unique software that computes these tensor-based indices. These descriptors, establish relations for two, three, and four atoms by using several (dis) similarity metrics or multimetrics, matrix transformations, cutoffs, local calculations and aggregation operators. The theoretical background of these N-linear indices is also presented. The QuBiLS-MIDAS software was developed in the Java programming language and employs the Chemical Development Kit library for the manipulation of the chemical structures and the calculation of the atomic properties. This software is composed by a desktop user-friendly interface and an Abstract Programming Interface library. The former was created to simplify the configuration of the different options of the MDs, whereas the library was designed to allow its easy integration to other software for chemoinformatics applications. This program provides functionalities for data cleaning tasks and for batch processing of the molecular indices. In addition, it offers parallel calculation of the MDs through the use of all available processors in current computers. The studies of complexity of the main algorithms demonstrate that these were efficiently implemented with respect to their trivial implementation. Lastly, the performance tests reveal that this software has a suitable behavior when the amount of processors is increased. Therefore, the QuBiLS-MIDAS software constitutes a useful application for the computation of the molecular indices based on N-linear algebraic maps and it can be used freely to perform chemoinformatics studies.

A number of quality issues that may arise when executing these scripts are identified. An automated quality assurance service is proposed that identifies the presence of these issues by automatically executing scripts across a range of environments. Test results are automatically published to a format capable of being consumed by script catalogues and social coding sites. This would serve as an independent signal of script trustworthiness and quality to script consumers and would allow developers to be made quickly aware of quality issues. As a result, potential consumers of scripts can be assured that a script is likely to work when applied to their particular environment. Script developers can be notified of compatibility issues and take steps to address them.",10.1109/SYNASC.2013.66

+1120,Article,Releasing Tools for International Disease Surveillance as Open-Source Software: A Case Study,"Since the development of tools for the Suite for Automated Global Electronic bioSurveillance (SAGES) began in 2008, the SAGES team and sponsor have envisioned the eventual release of these tools as open-source software to the global public health and technology communities. Open-source software allows members of the public to study, customize, and operate their own local copies of the software and source code, often without monetary fees. As such, releasing SAGES as open-source software assures prospective users that they retain complete control over the health data collected by SAGES-based systems, and aligns well with the model of self-sustainability intended for the operation of SAGES systems in resource-limited settings. Preparing two SAGES tools, OpenESSENCE and SAGES Mobile, for release as open-source software projects entailed a multifaceted, months-long effort that spanned policy, technical, and community considerations. This article describes the issues, trade-offs, and decisions that were addressed leading up to the successful open-source release of OpenESSENCE and SAGES Mobile in June 2013. The aim of this case study is to inform future Johns Hopkins University Applied Physics Laboratory (APL) and external efforts to release open-source software.",NA
+1122,Article,Resources contributing to gaining competitive advantage for open source software projects: An application of resource-based theory,"Open Source Software (OSS) is an important asset in today's software-intensive society. The success of OSS projects is highly dependent on a number of factors. These factors must be understood and managed as an OSS project progresses. Thus, project management of an OSS project has a decisive role in ensuring the success of its software. The objective of the research is to increase the understanding of the resources affecting the competitiveness of OSS projects. Herewith, the responsiveness of OSS projects to users' needs is assessed via an investigation of the defect-fixing process. A Resource-Based View of the firm (RBV) is used to build theoretical justifications for a set of hypotheses proposed in this study. Data gathered from 427 OSS projects confirmed that developers' interest in and users' contribution to the project as well as frequently updating and releasing the software affect the project's ability to gain competitive advantage through effective defect-fixing. It is also shown that OSS projects that are more popular and have a higher level of organizational communication than others are more likely to gain competitive advantage through effective defect-fixing. Finally, implications of the results for practitioners and the research community are presented. (C) 2013 Elsevier Ltd. APM and IPMA. All rights reserved.",10.1016/j.ijproman.2013.03.002
+1126,InProceedings,Risk Based Testing of Open Source Software (OSS),"Open Source Software (OSS) has become a strategic asset for a number of reasons, such as its short timeto-market software service and product delivery, reduced development and maintenance costs, introduction of innovative features and its customization capabilities. By 2016 an estimated 95\\% of all commercial software packages will include OSS components. This pervasive adoption is not without risks for an industry that has experienced significant failures in product quality, timelines and delivery costs. Exhaustive testing of any software system and, specifically, of open source software components is usually not feasible due to limitations in time and resources. In risk-based testing approach test cases are selected and scheduled based on software risk analysis. This research introduces the strategy of risk-based adaptive testing of OSS by combining information on the OSS community ecosystem with risk-driven tests selection and scheduling strategy. A key feature of the proposed approach is the monitoring and analysis of OSS community dynamics, including chats and email communications, blogs, repositories of bugs and fixes, and more. The community and its dynamics are then monitored to detect anomaly communication between the community members. Our approach is demonstrated in the XWiki OSS, a Java-based environment that allows for the storing of structured data and the execution of server side scripts within the wiki interface. We illustrate our concepts, methods and approach behind risk based testing.",10.1109/COMPSACW.2014.107
+1128,Article,Risk of adopting mission-critical OSS applications: an interpretive case study,"Purpose - This study aims to explore the process of open source software (OSS) adoption in small- and medium-sized enterprises (SMEs), and more specifically open source enterprise resource planning (ERP) as a ``mission critical{''} OSS application in manufacturing. It also addresses the fundamental issue of ERP risk management that shapes this process. Design/methodology/approach - The approach is done through an interpretive case study of a small Canadian manufacturer that has adopted an open source ERP system. Findings - Interpreted in the light of the IT risk management, OSS and packaged application adoption literatures, results indicate that the small manufacturer successfully managed the adoption process in a rather intuitive manner, based on one guiding principle and nine practices. In analyzing the data, diffusion of innovation theory appeared to fit rather well with the situation observed and to offer rich insights to explain the mission-critical OSS adoption process. Research limitations/implications - A single case study of successful IT adoption should be eventually counterbalanced by future cases considered to be partial or total failures, using a wider multiple case study approach for comparative purposes. And this should include alternative theoretical interpretations and more detailed empirical work on the extent to which the distinctive features of OSS make its adoption more or less risk-laden. This initial effort should also be followed by further research on mission-critical OSS adoption in contexts other than SMEs (e.g. healthcare organizations) and other than ERP (e.g. customer-relationship management). Practical implications - This research confirms that open source is a credible alternative for SMEs that decide willingly or under external pressure to adopt a mission-critical system such as ERP. Moreover, it suggests that a high level of formalization is not always necessary. Originality/value - The authors argue that rich insights into the dynamics of the mission-critical OSS adoption process can be obtained by framing this process within an IT risk management context.",10.1108/IJOPM-03-2012-0117

The past 15 years have seen vast improvements in the collection, analysis, visualization, and reporting of public health data. Resource-limited countries have lagged behind because of challenges in information technology infrastructure and public health resources. The Suite for Automated Global Electronic bioSurveillance (SAGES) is a collection of modular, open-source software tools designed to meet the challenges of electronic disease surveillance in resource-limited settings. Individual SAGES tools may be used in concert with existing surveillance applications or en masse for an end-to-end biosurveillance capability. This flexibility allows for the development of an inexpensive, customized, and sustainable disease surveillance system. The ability to rapidly assess anomalous disease activity may lead to more efficient use of limited resources and better compliance with World Health Organization International Health Regulations.",NA

To teach SE with OSS, however, it is necessary to select uniform projects of appropriate size and complexity. This paper reports on our search for suitable OSS projects to teach an introductory SE course with a focus on maintenance and evolution. The search turned out to be quite labor intensive and cumbersome, contrary to our expectations that it would be quick and simple. The chosen projects successfully demonstrated the maintenance challenges, highlighting the promise of using OSS.

+1140,Article,Simulating upgrades of complex systems: The case of Free and Open Source Software,"Context: The upgrade of complex systems is intrinsically difficult and requires techniques, algorithms, and methods which are both expressive and computationally feasible in order to be used in practice. In the case of FOSS (Free and Open Source Software) systems, many upgrade errors cannot be discovered by current upgrade managers and then a system upgrade can potentially lead the system to an inconsistent and incoherent state. Objective: The objective of this paper is to propose an approach to simulate the upgrade of complex systems in order to predict errors before they affect the real system. Method: The approach promotes the use of model-driven engineering techniques to simulate the upgrade of complex systems. The basic idea is to have a model-based description of the system to be upgraded and to make use of model transformations to perform the upgrade on a source model so to obtain a target model representing the state of the upgraded system. Results: We provide an implementation of the simulator, which is tailored to FOSS systems. The architecture of the simulator is distribution independent so that it can be easily instantiated to specific distributions. The simulator takes into account also pre and post-installation scripts that equip each distribution package. This feature is extremely important since maintainer scripts are full-fledged programs that are run with system administration rights. Conclusions: The paper shows the kind of errors the simulator is able to predict before upgrading the real system, and how the approach improves the state of the art of package managers while integrated in real Linux distribution installations.

Understanding software means more than understanding the source code; it also refers to the other facts related to that particular software. Sometimes even experienced developers can be overwhelmed by a project's extensive development capabilities. In the development process, project leaders (PLs) have overall knowledge about the project and are keenly aware of its vision. Other members have only partial knowledge of the functions assigned to them. In this research, we propose a model to design ontology to support software comprehension and handle issues of knowledge management throughout the development process.

Research has shown that visual modeling of complex software projects has benefits throughout the software lifecycle. Then why is it that software architecture modeling is so conspicuously missing from popular online open source code repositories? How can including visual documentation improve the overall quality of open source software projects? Our goal is to answer both of these questions and bridge the gap between traditional software engineering best practices and open source development by applying a software architecture documentation methodology using Unified Modeling Language, called 5W1H Re-Doc, on a real open source project for managing identity and access, MITREid Connect. We analyze the effect of a model-driven software engineering approach on collaboration of open source contributors, quality of specification conformance, and state-of-the-art of architecture modeling.

Traditionally, RE has been considered as a centralized, collocated, and phase-specific process. However, in open-source software (OSS) development environment, the core RE activities are iterative and dynamic and follow a rather decentralized software engineering paradigm. This crosscutting characteristic of open-source RE can be conceptualized using the ``Twin Peaks{''} model that weaves RE together with software architecture. Although many weaving mechanisms have been proposed in recent years, lack of theoretical underpinning limits a mechanism's applicability and usefulness in different scenarios. In this research proposal, we hypothesize stakeholders' social interaction as an ecologically valid weaving mechanism of the ``Twin Peaks{''} in open-source RE. We further outline a concrete research plan to examine the generalizability of this weaving mechanism for three activities: requirements identification, requirements implementation, and creativity in RE. Carrying out this research plan will enable us to gain valuable insights to generate guidelines for enhancing software engineering practice in relevant areas.",NA

In this research, we look at FLOSS developers' relationships in terms of positive evaluations given by others. Using this perspective, we examine how FLOSS developers' reputation among members within and beyond the project community affects their projects' ability to attract new developers. We draw on Social Resource Theory (SRT) and hypothesize that developers with a high reputation among others enjoy high visibility and credibility, which in turn helps their projects to attract new members.

OSS is a complicated social process to understand. OSS is a multi-faceted phenomenon including code, a licensing structure, a community, development best practices, a method of diffusion. However, the current OSS collaborative researches place too much emphasis on collaborative behaviors, but ignore the study on collaborative process. By using the social network theory to abstract collaborative network topology, this paper proposes a method for constructing social network model, which considers both the contact relationship and level of collaboration between collaborators. Based on the definition of three types of contact behavior, this paper presents an approach to measuring the contact relationship intensity. Based on introducing and improving TF-IDF (term frequency-inverse document frequency), this paper presents the methods for calculating tag weights and work similarity between collaborators.

However, finding the desired software through tags in these communities such as Freecode and ohloh is still challenging because of tag insufficiency. In this paper, we propose TRG (tag recommendation based on semantic graph), a novel approach to discovering and enriching tags of open source software. Firstly, we propose a semantic graph to model the semantic correlations between tags and the words in software descriptions. Then based on the graph, we design an effective algorithm to recommend tags for software. With comprehensive experiments on large-scale open source software datasets by comparing with several typical related works, we demonstrate the effectiveness and efficiency of our method in recommending proper tags.",10.1007/s11704-013-2394-x

The purpose of this study is to investigate how commercial open source software affects the pricing (market share or profit) of proprietary software producer, consumer surplus and social welfare. Design/methodology: To analyze the impact of commercial open source software on proprietary software producer, this study constructs two vertical-differentiation models: the basic model considers proprietary software only competing with community open source software, and its extended one considers proprietary software competing with both community and commercial open source software. Findings: This study mainly finds that the presence of commercial open source software can lead to the decrease of the software price and profit for proprietary software producer, while the consumer surplus and social welfare will be increased. However, it does not necessarily cause the decline in the market share for proprietary software producer.

The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach - A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings - While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment.

+1180,Article,The {Emergence} of an {Organizational} {Field}: {The} {Case} of {Open} {Source} {Software},"Institutional theory offers a very powerful lens to understand and explain societal phenomena. In the context of innovation and technology, this perspective provides insights that complement the understandings derived from a focus on just technology or economics. Adopting this standpoint, this paper examines the emergence of the organizational field of open source software as a response to the norms of propriety software that were unacceptable to many passionate software researchers and programmers. The context of software product development has some unique characteristics that separates it from other industries. First, software products are information goods. In general, information goods have very high fixed costs of development and low marginal costs of reproduction which often leads to market inefficiencies. Second, IP protection has the potential to exaggerate the problem of market inefficiencies. Third, software is an input and also an output of the production function and IP protection has the potential to make the cost of software products prohibitively high. Fourth, the Internet has created the potential for the larger society to participate in the production process. These features of the software industry influence the dynamics among software professionals and orgnizations creating a distinctive context which can be better understood through the lens of institutional theory.According to institution theory, organizations seek to obtain legitimacy, which goes beyond technological or economic performance, by conforming to institutional requirements in a context. There are three forms of legitimacy. Pragmatic legitimacy, based on regulative requirements, is acquired by complying with the legal and regulative rules in the organizational field. Moral legitimacy, based on normative requirements, is obtained by ensuring that the activities of an organization promote societal good or welfare. Finally, cognitive legitimacy is derived from the extent to which the activities of an organization mesh with the taken-for-granted norms in the larger context. While institutions are normally sustained for long, they do experience change. Institutional change is driven by institutional entrepreneurs who create, maintain, and disrupt the practices that are considered legitimate, and challenge the boundaries that demarcate one field from another.The findings of this study capture the intricate dynamics and interactions among institutional requirements, software professionals and organizations that led to the norms of the institution of propriety software being challenged. It suggests that the process of institutional change can lead to the creation of a new alternate organizational field leaving the original field largely untouched. This paper contributes to the understanding of the software industry and suggests implications for other industries that produce information goods.",10.1177/0256090920140211
+1182,Article,The {Governance} and {Control} of {Open} {Source} {Software} {Projects}: {JMIS},"A comprehensive set of governance mechanisms and dimensions were investigated to identify combinations of mechanisms that are effectively used together in on-going volunteer-based open source software (OSS) projects. Three configurations were identified: Defined Community, Open Community, and Authoritarian Community. Notably, Defined Community governance had the strongest coordination and project climate and had the most extensive use of outcome, behavior, and clan control mechanisms (controller driven). The controls in the Defined Community governance configuration appear to effectively enable open, coordinated contribution and participation from a wide variety of talented developers (one of the virtues of open source development) while managing the development process and outcomes. The results add to our theoretical understanding of control in different types of information systems projects, as the combination of control modes found in OSS projects is different from those found in previous research for internal or outsourced information systems development projects. This could be due to unique features of OSS projects, such as volunteer participation and the controller being part of the development team. The results provide guidance for practitioners about how to combine 19 identified governance mechanisms into effective project governance that stimulates productive participation.

+1183,InProceedings,Theorizing Modes of Open Source Software Development,"Open Source Software (OSS) development is distributed across actors and artifacts and involves translating diffuse representations into distinct sets of contiguous code artifacts. Despite the highly distributed and dynamic nature of OSS development, it is often described in unitary, monolithic terms - an unfortunate situation which masks considerable variance across OSS development processes. Therefore we explore reasons for systematic variance in these processes so as to enable more effective OSS development practices. Drawing on theory of distributed cognition, we develop a language of cognitive translations, which occur within and across distributed social arrangements and structural conditions of sharing knowledge. This language provides micro-foundations for understanding how different modes of OSS development emerge. Through examining how generative characteristics of social and structural distributions in OSS shape distinct development pathways, we propose a theoretically derived typology explaining the characteristics, dynamics, and conditions for success of different modes of OSS development.",10.1109/HICSS.2014.560

The RSS was scoured firstly in strongly alkaline electrolyzed water (SAEW, pH >= 11.5) consisting mainly of hydroxyl ions by boiling for 30 min and then treated by the traditional scouring procedure (without alkaline compounds), resulting in refined silk floss. The recycled SAEW containing sericin was separated by ultrafiltration into a retentate with a range of high molecular mass values accounting for 10\\% (w/w) of the cocoon shell and the filtrate was separated by nanofiltration into a purified H2O filtrate and a retentate containing oligopeptides and free amino acids, which can be used directly as food additives or in biological growth media. The ultrafiltration retentate was hydrolyzed by papain under three different conditions into three groups of sericin peptides with high, middle or low molecular mass. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and gel permeation high-performance liquid chromatography (GP-HPLC) showed the molecular mass of these sericin peptides was in the range 0.2-60, 0.2 -30 and 0.2-15 kDa. These clean products have a variety of applications, including coating materials for surface modification, cell culture media and food additives. The procedure described here could be applied to the manufacture of silk floss quilts and the process of refining raw silk, which results in three clean products of the silk protein fibroin (i.e. stripped of sericin) and reduces environmental pollution from scouring waste containing sericin.

Testing on a sample of 176 OSS projects from Sourceforge.net, we showed that a negative quadratic relationship exists between the variation in structural embeddedness of the OSS user support network and the software popularity. Further, as hypothesized, the variation in junctional embeddedness was found to positively impact the OSS popularity. Theoretical and practical implications of the study are discussed.

Behind the expansion, there exist OSS development communities, where voluntary engineers dedicate their time and effort for the improvement. Considering development engineers in the companies as input resources, it is important to investigate the output of business growth. In this study, we conducted questionnaire survey to Japanese IT companies in 2013, and then analyzed the present state and relation between OSS utilization and development contribution. Our study revealed that Japanese IT companies are rather free riders of OSS, the volume of development contributions are far less than that of utilization. With regard to the effect on the business growth, the results of correlation analysis implicate that OSS utilization is related to the sales growth in the present term and that development contribution is related to the future growth of the employee number in the company. In order to explore the direct effect on the business growth, we constructed the models of multiple-logistic and logistic analyses, however, no direct and explicit determinants are found from the results of the analyses. Our research endeavors to investigate the OSS effect on the business growth are still on the way, but it is meaningful to provide the present state in numbers and hopefully this will lay some foundation for further study in this field.",10.1145/2641580.2641588

+1198,Article,"Workflow for High-content, Individual Cell Quantification of Fluorescent Markers from Universal Microscope Data, Supported by Open Source Software","Advances in understanding the control mechanisms governing the behavior of cells in adherent mammalian tissue culture models are becoming increasingly dependent on modes of single-cell analysis. Methods which deliver composite data reflecting the mean values of biomarkers from cell populations risk losing subpopulation dynamics that reflect the heterogeneity of the studied biological system. In keeping with this, traditional approaches are being replaced by, or supported with, more sophisticated forms of cellular assay developed to allow assessment by high-content microscopy. These assays potentially generate large numbers of images of fluorescent biomarkers, which enabled by accompanying proprietary software packages, allows for multi-parametric measurements per cell. However, the relatively high capital costs and overspecialization of many of these devices have prevented their accessibility to many investigators. Described here is a universally applicable workflow for the quantification of multiple fluorescent marker intensities from specific subcellular regions of individual cells suitable for use with images from most fluorescent microscopes. Key to this workflow is the implementation of the freely available Cell Profiler software(1) to distinguish individual cells in these images, segment them into defined subcellular regions and deliver fluorescence marker intensity values specific to these regions. The extraction of individual cell intensity values from image data is the central purpose of this workflow and will be illustrated with the analysis of control data from a siRNA screen for G1 checkpoint regulators in adherent human cells. However, the workflow presented here can be applied to analysis of data from other means of cell perturbation (e.g., compound screens) and other forms of fluorescence based cellular markers and thus should be useful for a wide range of laboratories.",10.3791/51882

There is a desire to establish means by which the shapes of planar polygons can be measured, characterized, and compared. I present the ShrinkShape2 toolbox, a completely redesigned set of end-user tools (an advancement of its precursor ShrinkShape) that is implemented seamlessly in the free and opensource R and SAGA GIS environments. This free, efficient, and accessible environment provides a multidimensional, rotation invariant, scale-controlled method for characterizing and comparing planar shapes and tools for visualizing results. ShrinkShape2 incrementally buffers polygons internally until the point of extinction; at each shrinking phase a series of summary metrics are computed to form spectra of index values that characterize general characteristics of shape structure and complexity. Demonstrations with simple synthetic shapes, political boundary maps, and a sample sub-Arctic pond demonstrate the ability to assess boundary complexity, pinch-points, and identify holes within larger shapes. For perfectly convex and compact shapes, perimeter decompositions will decrease linearly and area decompositions will decrease according to one limb of a second-order polynomial function relative to the cumulative shrinking distance.

+1211,Article,A model-driven approach to detect faults in FOSS systems,"Free and Open-Source Software (FOSS) Linux distributions are among the most complex modern software systems. They are made of thousands of components (software packages) evolving rapidly without centralized coordination. The upgrade of FOSS systems is managed by meta-installers, which solve package dependencies and conflicts and lead the system to a new system configuration by installing or removing packages. Current tools are able to predict a very limited set of upgrade faults before deployment, and this leaves a wide range of faults unpredicted. In this paper, we focus on faults that remain unpredicted, for example, missing packages, packages that are not properly installed, and missing services, with the aim of providing a solution for them. Specifically, in this paper, we propose a model-driven approach and supporting tools to prevent specific classes of system configuration faults before performing the real upgrade. Once the system configuration is represented as a model, the configuration model is evaluated by means of queries, each devoted to discover a specific class of faults. The approach is intrinsically extensible so that user communities can add new queries when new classes of faults are identified. The approach has been validated by executing the fault detector on configuration models in which faults have been intentionally injected and by analyzing produced results.

+1212,InProceedings,A multiple case study of small free software businesses as social entrepreneurships,"Free/libre and open source software are frequently described as a single community or movement. The difference between free software and open source ideology may influence founders, resulting in different types of companies being created. Specifically, the relationship between free/libre software ideology and social entrepreneurships is investigated. This paper presents seven case studies of businesses, five of which were founded by people who identify with the free/libre software movement. The result is a theory that small businesses founded by free/libre software advocates have three characteristics of social entrepreneurships. First, social benefit is prioritized over wealth creation. Second, the business's social mission is not incidental but is furthered through its for-pro fit activities, rather than supported by the company's profits. Third, the company's success is de fined in part by the success of its social mission. Free/libre software entrepreneurs who recognize their activities as social entrepreneurships can bene fit from the existing literature on the unique challenges faced by socially-oriented businesses.",10.1145/2788993.2789830

In such areas, ranging from environmental monitoring to precision agriculture, the ortophotos are the most commonly requested digital photogrammetric product. In fact, by using a GIS platform, the ortophotos can enable the integration of radiometric and spectral image data with the geographic and cartographic data and allow us to expand the spatial analysis to other types of attribute data. In this paper we present a methodology for the automatic production of ortophotos in urban areas by using UAVs and open source photogrammetric software. The potential and limits of this technology are assessed in the context of updating a municipal spatial database. The results show that the synergistic use of UAVs and open source photogrammetric software can be effectively used to produce ortophototos of small urban areas with an excellent quality/price ratio.",10.14195/978-989-26-0983-6\\_42
+1218,Article,Adopting open source software in public administration: The importance of boundary spanners and political commitment,"Open source software (OSS) adoption in public administrations around the world has been uneven. Despite the substantive economic and efficiency-related implications of OSS adoption, there is surprisingly little research into the determinants of the diffusion of OSS across public sector jurisdictions. In this article we explore the variation in OSS adoption among Dutch local administrations. The Dutch central government adopted a policy to stimulate the use of OSS in the public sector, but the non-mandatory character of the policy resulted in great differences in the degree of adoption of OSS at the local level. Using data from a new survey of municipalities in the Netherlands and proportional odds statistical models to analyze the data, we show that the degree of OSS adoption crucially depends on the presence of boundary spanners and political commitment within the local government On the other hand, oft-suspected factors like financial stress and jurisdiction size have no discernible effects. Our findings have implications for understanding the spread of OSS in the public sector and for public policies designed to encourage OSS diffusion.

+1219,Article,Adoption of OSS components: A goal-oriented approach,"Open Source Software (OSS) has become a strategic asset for a number of reasons, such as short time-to-market software delivery, reduced development and maintenance costs, and its customization capabilities. Therefore, organizations are increasingly becoming OSS adopters, either as a result of a strategic decision or because it is almost unavoidable nowadays, given the fact that most commercial software also relies at some extent in OSS infrastructure. The way in which organizations adopt OSS affects and shapes their businesses. Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. In this paper, we propose to model OSS adoption strategies using a goal-oriented notation, in which different actors state their objectives and dependencies on each other. These models describe the consequences of adopting one such strategy or another: which are the strategic and operational goals that are supported, which are the resources that emerge, etc. The models rely on an OSS ontology, built upon a systematic literature review, which comprises the activities and resources that characterize these strategies. Different OSS adoption strategy models arrange these ontology elements in diverse ways. In order to assess which is the OSS adoption strategy that better fits the organization needs, the notion of model coverage is introduced, which allows to measure the degree of concordance among every strategy with the model of the organization by comparing the respective models. The approach is illustrated with an example of application in a big telecommunications company. (C) 2015 Elsevier B.V. All rights reserved.",10.1016/j.datak.2015.06.007

The TOE (Technology, Organization and Environment) framework has been used to study the influence of technological, organizational, and environmental factors considered by companies when adopting OSS. In this work, we collected data through online surveys answered by workers in IT companies in the state of Minas Gerais, Brazil. The proposed model for determining the impact of each factor on the adoption of OSS and on the business model practiced by IT companies was evaluated by using structural equations. The results show that three groups of factors impact the way of OSS adoption. Organizational and technological factors are the most relevant, whereas for business models only environmental factors are relevant. The most relevant technological factor identified is ""reduced hardware and software costs""; the most relevant organizational factor is ""flexibility of IT structure""; and the most relevant environmental factor is ""reports of successful use of OSS"". We verified that IT companies in Minas Gerais use OSS in software development, either by incorporating OSS components into their software products or by employing OSS tools for software development.",NA

Adopting OSS software components introduces some risks that can affect the adopter organization's business goals, therefore they need to be considered. To assess these risks, it is required to understand the socio-technical structures that interrelate the stakeholders in the OSS ecosystem, and how these structures may propagate the potential risks to them. In this paper, we study the connection between OSS adoption risks and OSS adopter organizations' business goals. We propose a model-based approach and analysis framework that combines two existing frameworks: the i{*} framework to model and reason about business goals, and the RiskML notation to represent and analyse OSS adoption risks.

+1224,Article,An Analysis of Problem-Solving Patterns in Open Source Software,"Open Source Software (OSS) has become an important environment where developers can create, exchange, and improve reusable software assets by collaborating with other developers. Although developers may find useful software assets to reuse from OSS for their projects, they usually experience difficulties in solving problems that occur while integrating the assets to their own software. We investigated data from major open source environments such as Sourceforge. net and GitHub, and learned that there is a common pattern of solving reuse-related problems in OSS. To analyze the pattern in detail, we have developed an ontological model to formally represent the symptoms and causes of the reuse-related problems, and the correlations between them. Based on this model, we collected data from Sourceforge. net, and built a knowledge base for the most common problem type. We extracted the core types of symptoms and causes for the problem type and calculated the number of correlations between the types of symptoms and causes. We found that there exist correlations between the symptoms and causes that are extracted from the discussion threads for the problem type, and about 60\\% of them are statistically significant. We also conducted a study to understand the effective timing of recommending solutions to the developers by analyzing the recall rates of finding the causes of the problems in a timeline. We figured that most of the important causes of a problem are discussed at the beginning of the forum discussion. This leads us to the conclusion that recommending the causes of a problem early by using our knowledge framework may help developers spend less amount of time to solve the problem (around 50\\% less time than solving the problem without using our framework).",10.1142/S0218194015500187

Architectural decay is caused by repeated changes to a system during its lifespan. Despite decay's prevalence, there is a relative dearth of empirical data regarding the nature of architectural changes that may lead to decay, and of developers' understanding of those changes. In this paper, we take a step toward addressing that scarcity by conducting an empirical study of changes found in software architectures spanning several hundred versions of 14 open-source systems. Our study reveals several new findings regarding the frequency of architectural changes in software systems, the common points of departure in a system's architecture during maintenance and evolution, the difference between system-level and component-level architectural change, and the suitability of a system's implementation-level structure as a proxy for its architecture.",10.1109/MSR.2015.29

When open source software libraries are used, software resources may be linked directly or indirectly with multiple open source licenses giving rise to potential license incompatibilities. Adequate support in license use is vital in order to avoid such violations and address how diverse licenses should be handled. In the current work we investigate software licensing giving a critical and comparative overview of existing assistive approaches and tools. These approaches are centered on three main categories: license information identification from source code and binaries, software metadata stored in code repositories, and license modeling and associated reasoning actions. We also give a formalization of the license compatibility problem and demonstrate the role of existing approaches in license use decisions. (C) 2014 Elsevier Inc.

The rSCA package is efficient in dealing with both continuous and discrete variables, as well as nonlinear relationships between the variables. It divides the sample sets of dependent variables into different subsets (or subclusters) through a series of cutting and merging operations based upon the theory of multivariate analysis of variance (MANOVA). The modeling results are given by a cluster tree, which includes both intermediate and leaf subclusters as well as the flow paths from the root of the tree to each leaf subcluster specified by a series of cutting and merging actions. The rSCA package is a handy and easy-to-use tool and is freely available at http://cran.r-project.org/package=rSCA.

Our goal is to analyze the connectivity structure of the social networks of contributors and to investigate the effect of the different social ties structures on developers' overall productivity to OSS projects. We, first, analyze the general structure of the social networks, e.g., graph distances and the degree distribution of the social networks. Our social network structure analysis confirms a power-law degree distribution and small-world characteristics. However, the degree mixing pattern shows that high degree nodes tend to connect more with low degree nodes suggesting a collaboration between experts and newbie developers. We further conduct the same analysis on affiliation networks and find that contributors tend to participate in projects of similar team sizes. Second, we study the correlation between various social factors (e.g., closeness and betweenness centrality, clustering coefficient and tie strength) and the productivity of the contributors in terms of the amount of contribution and commitment to OSS projects. The analysis is conducted under the contexts of global and local networks, where a global network analysis considers a developer's connectivity in the whole OSS community network, whereas a local network analysis considers a developer's connectivity within a team network that is affiliated to a project. The analysis demonstrates evident influence of the social factors on the developers' overall productivity.",10.1007/978-3-319-19003-7\\_4
+1239,Article,Application of Survival Model to Understand Open Source Software Release,"One of the recurrent themes in open source software research is to understand the impacts of various project characteristics on its success. Open source software (OSS) projects rely on voluntary participation of developers and tend to be continually in development. Hence, an important measure of success is the time it takes for an OSS project to release a stable version to its users. However, there is little research on this success measure and how the OSS characteristics enable or delay the progress towards stable release. In this study, we use survival analysis technique on open source project data to explore the impacts of OSS characteristics on the time it takes to release stable software versions. We find that when compared to the interest of developers in the project, interest of end-users has a greater positive effect on an OSS project progress towards stable release. Our findings also suggest that the use of C and C-like programming languages or a Weak-Copyleft license for the open source project negatively impact the project's time to reach stable status. In OSS projects less than 8 months since becoming public, the use of a Strong-Copyleft license positively affects the project's progress. One of the implications of our findings is that OSS project administrators should control software change requests or form smaller developer groups to better control the delays due to higher developer interest in their projects.",10.17705/1pais.07201

This technology has provided new possibilities to visualize complex medical data through generation of 3-dimensional (3D) physical models via additive manufacturing that can be eventually utilised to assist in diagnosis, surgical planning, implant design, and patient management. Although the study on the construction of cranio-maxillofacial implant based on computer modelling and advanced biomaterial are growing rapidly from other parts of the world, however, in Malaysia is scanty, especially with open source application. For this reason, it leads us to embark in a study to produce a potential locally cranio-maxillofacial implant with equivalent standard as compared to the commercially available product applying open source software.

+1244,Article,Building a virtual simulation platform for quasistatic breast ultrasound elastography using open source software: A preliminary investigation,"Purpose: Quasistatic ultrasound elastography (QUE) is being used to augment in vivo characterization of breast lesions. Results from early clinical trials indicated that there was a lack of confidence in image interpretation. Such confidence can only be gained through rigorous imaging tests using complex, heterogeneous but known media. The objective of this study is to build a virtual breast QUE simulation platform in the public domain that can be used not only for innovative QUE research but also for rigorous imaging tests. Methods: The main thrust of this work is to streamline biomedical ultrasound simulations by leveraging existing open source software packages including Field II (ultrasound simulator), VTK (geometrical visualization and processing), FEBio {[}finite element (FE) analysis], and Tetgen (mesh generator). However, integration of these open source packages is nontrivial and requires interdisciplinary knowledge. In the first step, a virtual breast model containing complex anatomical geometries was created through a novel combination of image-based landmark structures and randomly distributed (small) structures. Image-based landmark structures were based on data from the NIH Visible Human Project. Subsequently, an unstructured FE-mesh was created by Tetgen. In the second step, randomly positioned point scatterers were placed within the meshed breast model through an octree-based algorithm to make a virtual breast ultrasound phantom. In the third step, an ultrasound simulator (Field II) was used to interrogate the virtual breast phantom to obtain simulated ultrasound echo data. Of note, tissue deformation generated using a FE-simulator (FEBio) was the basis of deforming the original virtual breast phantom in order to obtain the postdeformation breast phantom for subsequent ultrasound simulations. Using the procedures described above, a full cycle of QUE simulations involving complex and highly heterogeneous virtual breast phantoms can be accomplished for the first time. Results: Representative examples were used to demonstrate capabilities of this virtual simulation platform. In the first set of three ultrasound simulation examples, three heterogeneous volumes of interest were selected from a virtual breast ultrasound phantom to perform sophisticated ultrasound simulations. These resultant B-mode images realistically represented the underlying complex but known media. In the second set of three QUE examples, advanced applications in QUE were simulated. The first QUE example was to show breast tumors with complex shapes and/or compositions. The resultant strain images showed complex patterns that were normally seen in freehand clinical ultrasound data. The second and third QUE examples demonstrated (deformation-dependent) nonlinear strain imaging and time-dependent strain imaging, respectively. Conclusions: The proposed virtual QUE platform was implemented and successfully tested in this study. Through show-case examples, the proposed work has demonstrated its capabilities of creating sophisticated QUE data in a way that cannot be done through the manufacture of physical tissue-mimicking phantoms and other software. This open software architecture will soon be made available in the public domain and can be readily adapted to meet specific needs of different research groups to drive innovations in QUE.

Moreover, it is expected that flood risk will continue to rise due to the combined effect of increasing numbers of people and economic assets in risk-prone areas and the effects of climate change. In order to mitigate the impact of natural hazards on European economies and societies, improved risk assessment, and management needs to be pursued. With the recent transition to a more risk-based approach in European flood management policy, flood analysis models have become an important part of flood risk management (FRM). In this context, free and open-source (FOSS) geospatial models provide better and more complete information to stakeholders regarding their compliance with the Flood Directive (2007/60/EC) for effective and collaborative FRM. A geospatial model is an essential tool to address the European challenge for comprehensive and sustainable FRM because it allows for the use of integrated social and economic quantitative risk outcomes in a spatio-temporal domain. Moreover, a FOSS model can support governance processes using an interactive, transparent and collaborative approach, providing a meaningful experience that both promotes learning and generates knowledge through a process of guided discovery regarding flood risk management. This article aims to organize the available knowledge and characteristics of the methods available to give operational recommendations and principles that can support authorities, local entities, and the stakeholders involved in decision-making with regard to flood risk management in their compliance with the Floods Directive (2007/60/EC).",10.3390/ijgi4042704

+1263,Article,"Dental Stem Cell Migration on Pulp Ceiling Cavities Filled with MTA, Dentin Chips, or Bio-Oss","MTA, Bio-Oss, and dentin chips have been successfully used in endodontics. The aim of this study was to assess the adhesion and migration of dental stem cells on human pulp ceiling cavities filled with these endodontic materials in an experimental model, which mimics the clinical conditions of regenerative endodontics. Cavities were formed, by a homemade mold, on untouched third molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities' surface and their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three materials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential morphology. Moreover, variations were observed when comparing cells numbers on cavity's filling versus the surrounding dentine disc. The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss. This was confirmed in the migration assay where a statistically significant lower number of cells migrated towards Bio-Oss as compared to MTA and dentin chips. This study highlights that MTA and dentin chips have a greater potential compared to Bio-Oss regarding the attraction of dental stem cells and are good candidates for bioengineered pulp regeneration.",10.1155/2015/189872
+1264,Article,Developer initiation and social interactions in OSS: A case study of the Apache Software Foundation,"Maintaining a productive and collaborative team of developers is essential to Open Source Software (OSS) success, and hinges upon the trust inherent among the team. Whether a project participant is initiated as a committer is a function of both his technical contributions and also his social interactions with other project participants. One's online social footprint is arguably easier to ascertain and gather than one's technical contributions e.g., gathering patch submission information requires mining multiple sources with different formats, and then merging the aliases from these sources. In contrast to prior work, where patch submission was found to be an essential ingredient to achieving committer status, here we investigate the extent to which the likelihood of achieving that status can be modeled solely as a social network phenomenon. For 6 different Apache Software Foundation OSS projects we compile and integrate a set of social measures of the communications network among OSS project participants and a set of technical measures, i.e., OSS developers' patch submission activities. We use these sets to predict whether a project participant will become a committer, and to characterize their socialization patterns around the time of becoming committer. We find that the social network metrics, in particular the amount of two-way communication a person participates in, are more significant predictors of one's likelihood to becoming a committer. Further, we find that this is true to the extent that other predictors, e.g., patch submission info, need not be included in the models. In addition, we show that future committers are easy to identify with great fidelity when using the first three months of data of their social activities. Moreover, only the first month of their social links are a very useful predictor, coming within 10 \\% of the three month data's predictions. Interestingly, we find that on average, for each project, one's level of socialization ramps up before the time of becoming a committer. After obtaining committer status, their social behavior is more individualized, falling into few distinct modes of behavior. In a significant number of projects, immediately after the initiation there is a notable social cooling-off period. Finally, we find that it is easier to become a committer earlier in the projects life cycle than it is later as the project matures. These results should provide insight on the social nature of gaining trust and advancing in status in distributed projects.",10.1007/s10664-014-9332-x
+1265,Article,Developers' Incentives and Open-Source Software Licensing: GPL vs BSD,"One of the puzzling aspects of open-source software (OSS) development is its public good nature. Individual developers contribute to developing the software, but do not hold the copyright to appropriate its value. This raises questions regarding motives behind such effort. We provide an integrated model of developers' incentives to describe OSS development and compare restrictive OSS licenses that force all modifications to be kept open with non-restrictive OSS licenses that allow proprietary ownership of modified works. Different incentives govern effort provision at different stages of the software development process. We show that open-source licenses can provide socially valuable software when a proprietary license fails to do so. We also show that restrictive OSS licenses generate greater effort provision in the design stage of software development relative to non-restrictive licenses. Endogenizing licensing choice, we find that a project leader chooses a non-restrictive OSS license if reputational concerns drive developers' incentives, a proprietary license when there is a large population of users in the market and a restrictive OSS license if user population is small but reputational benefit is high. Our results resonate well with empirical findings and suggest additional testable implications about the relationship between licensing and software project characteristics. Finally, we also find that the market under-provides restrictive OSS licenses relative to the efficient level, suggesting the need for subsidizing restrictive licenses in some cases.",10.1515/bejeap-2014-0007

Consequently, support in the exchange of data, information, and knowledge is becoming the key issue in computer technology today. The increasing volume of data available on the Web makes information retrieval a tedious and difficult task. Researchers are now exploring the possibility of creating a semantic web, in which meaning is made explicit, allowing machines to process and integrate web resources intelligently. The vision of the semantic web introduces the next generation of the Web by establishing a layer of machine-understandable data. The success of the semantic web depends on the easy creation, integration and use of semantic data, which will depend on web ontology. The faceted approach towards analyzing and representing knowledge given by S R Ranganathan would be useful in this regard. Ontology development in different fields is one such area where this approach given by Ranganathan could be applied.

+1268,Article,Does Open Source Software influence economic growth?,"Open Source Software (OSS) community is challenging the traditional meaning of property rights. The way the OSS products are developed and distributed is questioning the right to exclude others from using the goods and introduces the right to distribute and modify software for free. The economic impact of the Open Source Software contribution is significant, it has been estimated that it represents c.a. 30\\% of the software market. There is an increasing interest in studying OSS communities, however there have been a small number of studies investigating the general role of the OSS in the economic growth. Therefore the lack of theory linking the economic growth and OSS contribution represents the main theoretical problem of this paper. The goal of this article is to prove that the existence of OSS communities increases the quantity of non-rival and non-excludable goods, which - according to endogenous model of growth - leads to economic growth. Additionally the study findings undermine the neoclassical theory of property rights in terms of non-rival and non-excludable goods. The structure of the paper is organized as follows. In section 1 the article focuses on the literature addressing the role of the non-rival and non-excludable goods in the theory of growth and theory of property rights. Section 2, contains the literature review of the OSS socio-economic phenomena and argues that the neoclassical theory of rights is inadequate to explain OSS market existence. Section 3 of the paper summarizes the main conclusions and discusses the general motivation behind the creation of the non-excludable and non-rival goods as well as the diminishing role of the egoism as the origin of the economic growth. From the methodological point of view the paper represents a literature review and a critical analysis of the endogenous growth theory and the theory of property rights.",NA

However, the nature of FLOSS is different from the software they have been using in the last decades. Its development model is distributed, and its authors are diverse as many volunteers and companies may collaborate in the project. In this paper, the authors want to shed some light on how to evaluate a FLOSS system by looking at the Moodle platform, which is currently the most used learning management system among educational institutions worldwide. In contrast with other evaluation models that have been proposed so far, the one presented here is based on retrieving historical information that can be obtained publicly from the Internet, allowing the authors to study its evolution.

+1272,InProceedings,Evaluation of Open-source Software Frameworks for High Fidelity Simulation of Cognitive Radio Networks,"High fidelity simulation of cognitive radio networks (CRN) requires a CRN software framework with librairies of components at all layers of the open systems interconnection (OSI) model (e.g. modulation schemes, protocols, routing algorithms) along with realistic channel models for simulating a high number of nodes. At the same time, the CRN software framework should provide interfaces with hardware platforms for testbed evaluation and hardware-in-the-loop (HIL). Unfortunately, there is no such software framework in the research community. This paper studies the combination of some open-source frameworks for high fidelity simulation of CRN. In particular, some challenges are highlighted for the combination of radio simulators (e.g. GNU Radio, CogWave) and network simulators (e.g. OMNeT++, ns3) at the level of network layer, data link layer and physical layer. Based on this evaluation, new extensions to the CogWave open-source software framework are proposed for high fidelity simulation of CRN.",NA

+1277,Article,Exploitation and Exploration Networks in Open Source Software Development: An Artifact-Level Analysis,"Open source software (OSS) development is an increasingly important paradigm of software development. However, key aspects of OSS such as the determinants of project success and motivations of developers in joining these projects are not well understood. Based on organizational theory, we propose that OSS activities of patch development and feature request can be classified as exploitation (implementation-oriented) and exploration (innovation-oriented) activities, respectively. We empirically examine how the structure of social network affects the success of patch-development and feature-request networks in OSS projects, using a data set collected from the SourceForge database. Our results provide empirical support for the view that patch development and feature request are exploitation and exploration activities, respectively. Network structures differ due to team formation differences and have a differential impact on development success based on the type of activity. The concepts of ambidextrous developers and ambidexterity are explored in the context of OSS projects. Collectively, our results indicate that studying OSS projects at the artifact level could improve our understanding of OSS project success and team formation. This, in turn, could lead to better management of OSS projects.",10.1080/07421222.2015.1029382
+1281,InProceedings,Exploring the Use of Labels to Categorize Issues in Open-Source Software Projects,"Reporting bugs, asking for new features and in general giving any kind of feedback is a common way to contribute to an Open-Source Software (OSS) project. This feedback is generally reported in the form of new issues for the project, managed by the so-called issue-trackers. One of the features provided by most issue-trackers is the possibility to define a set of labels/tags to classify the issues and, at least in theory, facilitate their management. Nevertheless, there is little empirical evidence to confirm that taking the time to categorize new issues has indeed a beneficial impact on the project evolution. In this paper we analyze a population of more than three million of GitHub projects and give some insights on how labels are used in them. Our preliminary results reveal that, even if the label mechanism is scarcely used, using labels favors the resolution of issues. Our analysis also suggests that not all projects use labels in the same way (e.g., for some labels are only a way to prioritize the project while others use them to signal their temporal evolution as they move along in the development workflow). Further research is needed to precisely characterize these label ``families{''} and learn more the ideal application scenarios for each of them.",NA

+1285,Article,"FiberApp: An Open-Source Software for Tracking and Analyzing Polymers, Filaments, Biomacromolecules, and Fibrous Objects","Biological semiflexible polymers and filaments such as collagen, fibronectin, actin, microtubules, coiled-coil proteins, DNA, siRNA, amyloid fibrils, etc., are ubiquitous in nature. In biology, these systems have a direct relation to critical processes ranging from the movement of actin or assembly of viruses at cellular interfaces to the growth of amyloid plaques in neuro-degenerative diseases. In technology and applied sciences, synthetic macromolecules or fibrous objects such as carbon nanotubes are involved in countless applications. Accessing their intrinsic properties at the single molecule level, such as their molecular conformations or intrinsic stiffness, is central to the understanding of these systems, their properties, and the design of related applications. In this Perspective we introduce FiberApp a new tracking and analysis software based on a cascade of algorithms describing structural and topological features of objects characterized by a very high length-to-width aspect ratio, generally described as ``fiber-like objects{''}. The program operates on images from any microscopic source (atomic force or transmission electron microscopy, optical, fluorescence, confocal, etc.), acquiring the spatial coordinates of objects by a semiautomated tracking procedure based on A{*} pathfinding algorithm followed by the application of active contour models and generating virtually any statistical, topological, and graphical output derivable from these coordinates. Demonstrative features of the software include statistical polymer physics analysis of fiber conformations, height, bond and pair correlation functions, mean-squared end-to-end distance and midpoint displacement, 2D order parameter, excess kurtosis, fractal exponent, height profile and its discrete Fourier transform, orientation, length, height, curvature, and kink angle distributions, providing an unprecedented structural description of filamentous synthetic and biological objects.",10.1021/ma502264c

In our investigation, we draw upon a data set consisting of 109 projects with 912 individual programmers and 110 involved firms and show how those different projects are governed in terms of project leadership. Our four hypotheses show that despite the wish for external knowledge from voluntary programmers firms are relying on own resources or those from other firms to control a project, that projects with low firm participation are mainly led by voluntary committers, and that projects with high firm participation are mainly led by paid leaders. This research extends the dominating literature by providing empirical evidence in that area and helps to deepen our understanding of firm participation in OSS projects as a form of open innovation activity.",10.1142/S0219877015500108

The forming process of FL-NCOH is clarified by tuning the hydrothermal reaction time. The result indicates that floccule-like nickel-cobalt hydroxide nanoclusters gradually become longer and slenderer nanowires to form FL-NCOH with the increase of reaction time. The dissolution-recrystallization of hydroxide plays an important role in the morphology control of nickel-cobalt hydroxide. The high specific surface area (106.5 m(2) g(-1)) and the suitable 3D structure endow the as-prepared FL-NCOH material high specific capacitance (up to 918.9 F g(-1) at the current density of 0.2 A g(-1)), good high-rate performance (594.2 F g(-1) even at 10.0 A g(-1)), and long cycle life (98.7 \\% capacitance retention after 3000 charge-discharge cycles at 2.0 A g(-1)).",10.1007/s11581-014-1319-5

Here, we evaluated biopsies of grafted bone with a mixture of autologous bone and Bio-Oss((R)) or BoneCeramic((R)) after two different healing time periods to understand the molecular process underlying bone formation after MSFE. Material and methodsSeven patients, following a bilateral split-mouth design model and needing a MSFE to allow implant placement, were recruited for this study. Right or left sinuses were grafted with autologous maxillary bone combined either with Bio-Oss((R)) or BoneCeramic((R)), respectively. Twenty biopsies were taken at the time of implant insertion after 4-5months or 6-8months of MSFE, and analyzed by micro-computed tomography (microCT) and gene-expression analysis. ResultsMicroCT analysis revealed no differences in the morphometric parameters or BMD either after 4-5months or 6-8months of MSFE between Bio-Oss((R)) and BoneCeramic((R)). At molecular level, a higher expression of bone forming gene Runx2 was observed after 4-5months of MSFE in the Bio-Oss((R)) compared with the BoneCeramic((R)) group.

The rise of open source (OS) software and OS tangible products, so-called open design, has challenged this understanding. Openness is often regarded as a dichotomous variable (open-source vs. closed-source) and it is assumed that online developer communities demand full opening of the product's source. In this paper we will explore openness as a gradual and multi-dimensional concept. We carried out an Internet survey (N = 270) among participants of 20 open design communities in the domain of IT hardware and consumer electronics. We find that open design projects pursue complex strategies short of complete openness and that communities value openness of software more highly than openness of hardware. Our findings suggest that open design companies can successfully implement strategies of partial openness to safeguard value capture without alienating their developer community.",NA

A framework and empirical analysis of different governance modes,"This paper explores how software firms can apply different types of governance approaches to open source software development projects (OSSDPs) and draws on control theory to propose that firms may influence OSSDPs by employing either leadership or resource deployment control. A matrix differentiating four types of OSSDPs: firm- versus community-initiated projects and one participating firm (single-vendor projects) versus many firms (multivendor projects), and accompanying hypotheses regarding a firm's participation for each type are developed. Using data from 83 Eclipse projects to test the hypotheses, findings indicate that (1) firms more actively employ both leadership and resource deployment in firm-initiated projects than in community-initiated ones and (2) firms are more likely to use resource deployment control over leadership control in multivendor projects. Key theoretical and managerial implications are discussed. (C) 2015 Elsevier Ltd. All rights reserved.",10.1016/j.infoandorg.2015.03.001

This is multi-platform software developed in the Java programming language, designed with a remarkably user-friendly graphical interface for the computation of a collection of information-theoretic functions adapted for rank-based unsupervised and supervised feature selection tasks. A total of 20 feature selection parameters are presented, with the unsupervised and supervised frameworks represented by 10 approaches in each case. Several information-theoretic parameters traditionally used as molecular descriptors (MDs) are adapted for use as unsupervised rank-based feature selection methods. On the other hand, a generalization scheme for the previously defined differential Shannon's entropy is discussed, as well as the introduction of Jeffreys information measure for supervised feature selection. Moreover, well-known information-theoretic feature selection parameters, such as information gain, gain ratio, and symmetrical uncertainty are incorporated to the IMMAN software (http://mobiosd-hub.com/imman-soft/), following an equal-interval discretization approach. IMMAN offers data pre-processing functionalities, such as missing values processing, dataset partitioning, and browsing. Moreover, single parameter or ensemble (multi-criteria) ranking options are provided. Consequently, this software is suitable for tasks like dimensionality reduction, feature ranking, as well as comparative diversity analysis of data matrices. Simple examples of applications performed with this program are presented. A comparative study between IMMAN and WEKA feature selection tools using the Arcene dataset was performed, demonstrating similar behavior. In addition, it is revealed that the use of IMMAN unsupervised feature selection methods improves the performance of both IMMAN and WEKA supervised algorithms.

They provide critical information and enhance environmental integrity in planning and development of GHG mitigation policy. The characteristics of a high quality inventory are that it follows good practice according to the IPCC guidelines. The key components of good practice are that the inventory is transparent to others, has accurate and complete emissions estimates for all gases, sources and sinks; has consistent application of methods across time; and is comparable to inventories from other countries {[}1]. While developed countries struggle with implementation of good practice, most can produce reasonably high quality inventories {[}2]. However, the task is more challenging in low lying pacific island countries. Some of the specific challenges include: lack of clarity on roles and responsibilities of agencies in preparing inventories; small teams with limited resources; difficulty in retaining expertise; incomplete or non-existent activity data; inconsistent data between inventories; absence of an archiving system for previous inventories; no QA/QC plan {[}3]. As part of the UN-REDD Programme project on ``Strengthening Regional Support to National Forest Monitoring Systems for REDD+ in the Pacific{''} a Regional Monitoring System has been developed to support low lying pacific island countries (Republic of Palau, Tuvalu, Cook Islands, Tonga, Republic of Kiribati, and Federated States of Micronesia). Using the Republic of Palau as a case study, we present this system and focus on four main challenges; 1) improving activity data compilation through systematic land use assessment 2) application of simple land use mapping algorithms 3) application of a regional geo-spatial portal to support improved data management 4) application of open-source land use analysis systems to help manage and analyze inventory data.",NA

A key factor for the success of a free software project is its development dynamics, dependent on the attraction and retention of users and developers. The license plays an important role in this scenario, because by imposing restrictions on the use of the source code it attracts potential contributors in a different way. The degree of restriction of the license and an indicator of success of free software were related: the time between stages, that is, the time spent to evolve through the various stages of development. The results indicated that projects licensed under non-restrictive terms progress faster than projects licensed under highly restrictive terms and that projects with restrictive licenses progress slower than projects with non-restrictive or highly restrictive licenses.",NA

With regard to the establishment of a web-mapping tool on airborne particulate matter (PM) concentration for the Euregio Meuse-Rhine located in the border region of Belgium, Germany and the Netherlands, this article describes the research on methodical and technical backgrounds implementing such a platform. An open-source solution was selected for presenting the data in a Web GIS (OpenLayers/GeoExt; both JavaScript-based), applying other free tools for data handling (Python), data management (PostgreSQL), geo-statistical modelling (Octave), geoprocessing (GRASS GIS/GDAL) and web mapping (MapServer). The multilingual, made-to-order online platform provides access to near-real time data on PM concentration as well as additional background information. In an open data section, commented configuration files for the Web GIS client are being made available for download. Furthermore, all geodata generated by the project is being published under public domain and can be retrieved in various formats or integrated into Desktop GIS as Web Map Services (WMS).

The photogrammetry provides high geometric accuracy and but allows us to see the texture of the object. With the emergence of free software in this area, it turns into one of the most accessible techniques.

These communities' survival, long-term success, and continuity demand a constant influx of newcomers. However, newcomers face many barriers when making their first contribution to an OSS project, leading in many cases to dropouts. Therefore, a major challenge for OSS projects is to provide ways to support newcomers during their first contribution. In this paper, our goal was to evaluate how the newcomers' perceived efficacy is influenced by the use of an environment that organizes the project information for developers who want to place their first contribution to an OSS project. To accomplish this goal, we created FLOSS coach, a portal aiming to support newcomers to OSS projects, which was implemented based on a model of barriers proposed in previous research. Then, we conducted a study, in which 46 students, split in case and control group, were asked to contribute to an OSS project. We assessed the newcomers' self-efficacy by conducting a questionnaire before and after the assignment. We found that presenting the information according to the model of barriers had a positive influence on newcomers' self-efficacy, empowered the newcomers, making them more confident and comfortable during the contribution process. However, there is also some indication that FLOSS coach did not lower the technical barriers.",10.1109/SBES.2015.10

This increasing attention is a result of the remarkable growth in the number of OSS applications in recent years. Despite an increased number of studies on OSS project success, the interrelationships among different success indicators of OSS projects are not well understood in literature. The present study reports on the interrelationships between the success measures of OSS projects, as defined by the ability of the project to attract user and developer interest, release management, project activity, and development sustainability. To test the relationships hypothesized, we gathered data from 1409 OSS projects over time (in two snapshots over a period of eight months). The results show the following: (a) project activity until any time period positively impacts the subsequent period's developer interest and development sustainability; (b) development sustainability positively drives user and developer interest; (c) release frequency positively influences the next period's developer interest, as well as development sustainability; (d) developer interest positively drives user interest.

+1323,Article,Knowledge sharing in open source software communities: motivations and management,"Purpose - This paper aims to add to the understanding of knowledge sharing in online communities through an investigation of the relationship between individual participant's motivations and management in open source software (OSS) communities. Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach - To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents' opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings - The analysis of the data reveals that the individual participant's satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value - Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members' satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.",10.1108/JKM-10-2014-0446

However, studies that specifically explore learning of software security in the context of open source development are scarce. This paper aims to empirically assess present knowledge sharing and learning about secure programming knowledge in the context of OSS communities utilized a socio-technical approach on OSS projects based on an ethnographic observation.

+1327,Article,Lessons learned from applying social network analysis on an industrial Free/Libre/Open Source Software ecosystem,"Many software projects are no longer done in-house by a single organization. Instead, we are in a new age where software is developed by a networked community of individuals and organizations, which base their relations to each other on mutual interest. Paradoxically, recent research suggests that software development can actually be jointly-developed by rival firms. For instance, it is known that the mobile-device makers Apple and Samsung kept collaborating in open source projects while running expensive patent wars in the court. Taking a case study approach, we explore how rival firms collaborate in the open source arena by employing a multi-method approach that combines qualitative analysis of archival data (QA) withmining software repositories (MSR) and Social Network Analysis (SNA). While exploring collaborative processes within the OpenStack ecosystem, our research contributes to Software Engineering research by exploring the role of groups, sub-communities and business models within a high-networked open source ecosystem. Surprising results point out that competition for the same revenue model (i.e., operating conflicting business models) does not necessary affect collaboration within the ecosystem. Moreover, while detecting the different sub-communities of the OpenStack community, we found out that the expected social tendency of developers to work with developers from same firm (i.e., homophony) did not hold within the OpenStack ecosystem. Furthermore, while addressing a novel, complex and unexplored open source case, this research also contributes to the management literature in coopetition strategy and high-tech entrepreneurship with a rich description on how heterogeneous actors within a high-networked ecosystem (involving individuals, startups, established firms and public organizations) joint-develop a complex infrastructure for big-data in the open source arena.",10.1186/s13174-015-0028-2

Although it is becoming the remote sensing platform of choice for planning and natural resource agencies that require three-dimensional information, the enormous data that are generated and the lack of available software analysis packages make LiDAR still unavailable to a typical user of spatial data. LiDARHub is a free and open source platform for web-based management, visualization and analysis of LiDAR data that enables development of online tools for LiDAR data processing in a web browser.

Passive users play a critical role in the adoption and diffusion of OSS, and we need more research to understand their behaviors and motivations. We address this gap by drawing on the sociological theory of community markers. The three community markers in the context of OSS are loyalty, ideology, and identification. We also draw on marketing literature to propose four contributory behaviors of passive users of OSS that we theorize to be impacted by the community markers: user brand-extension, word-of-mouth, endorsement, and community involvement. We further classify passive users' contributory behaviors according to the difficulty of their enactment and examine the differential influence of the OSS community markers. Partial-least squares (PLS) analyses of data obtained through a survey of passive users of an OSS product provide support for the majority of the hypotheses.",10.17705/1jais.00405

+1333,Article,Measurement of ground displacement from optical satellite image correlation using the free open-source software MicMac,"Image correlation is one of the most efficient techniques to determine horizontal ground displacements due to earthquakes, landslides, ice flows or sand dune migrations. Analyzing these deformations allows a better understanding of the causes and mechanisms of the events. By using sub-pixel correlation on before- and after-event ortho-images obtained from high resolution satellite images it is possible to compute the displacement field with high planimetric resolution. In this paper, we focus on measuring the ground displacements due to seismotectonic events. The three sub-pixel correlators used are: COSI-Corr - developed by Caltech, a free, closed-source correlator, dependent on commercial software (ENVI) and widely used by the geoscience community for measuring ground displacement; Medicis - developed by CNES, also a closed-source correlator capable of measuring this type of deformation; and MicMac - developed by IGN, the free open-source correlator we study and tune for measuring fine ground displacements. We measured horizontal ground deformation using these three correlators on SPOT images in three study cases: the 2001 Kokoxili earthquake, the 2005 dyke intrusion in the Afar depression and the 2008 Yutian earthquake.

Through professional and occupational competences, individuals are able to deal with the requirements of the phenomenon of globalization. Therefore, many countries have been involved in the creation of quality assurance of educational systems in order to design more flexible curricula, more open to knowledge society. They meet the vast training needs, provide a variety of educational strategies and drive academic mobility and collaborative inter or multidisciplinary projects. In this respect, educational institutions are called to promote methodologies focused on the study of curriculum to diagnose and base the formulation of improvement plans for quality assurance. This project formulated a methodology to examine and determine the level of curricular flexibility. It was based on a prototype of an information system developed with free software that supported management indicators and represented different manifestations of flexibility. On the other hand, the Viable System Model provided the theoretical foundation to specify the study and the organizational diagnosis and to identify the information needs among defined sub-systems, including environment. The prototype of the information system was designed so that academic programs within a higher education institution have the capacity to structure several studies of curriculum flexibility over time in order to establish the necessary comparatives and to be a knowledge-based supply for future curriculum reforms and a basis for quality assurance processes.

+1340,InProceedings,Motivations for Knowledge Sharing in Free Software Communities,"Knowledge sharing is a key aspect for a community of practice. Free software communities can be considered communities of practice, since they aggregate people interested in donating and collecting, that is, sharing knowledge about free software. According to the literature, the donation and collection of knowledge are motivated by different factors and these motivations may vary depending on the context. Free software communities may include members from different countries and backgrounds, which can make keeping such communities active and vigorous a challenge. This study aims to identify the motivations for knowledge sharing behaviour that are susceptible to leadership actions in free software communities. The research was carried out in three phases. First, a qualitative study involving twenty semi-structured interviews was conducted among members of a free software community, who suggested sixteen motivations for knowledge sharing behaviour. These motivations were then organized into three groups, each with a specific focus: three motivations only influence knowledge collection and focus on the knowledge itself; nine motivations only influence knowledge donation and focus on the individual; and four motivations influence both knowledge collection and knowledge donation, and focus on the relationships among individuals. After that, based on the groups of motivation identified in the previous phase, five leaders from different communities of practice were interviewed with the aim of identifying the main motivations that would be susceptible to their actions, which were knowledge quality, ease of access to knowledge, recognition, community support for knowledge sharing, learning and professional reasons. Finally, these six main motivations indicated by the leaders were tested in a quantitative phase involving 260 members of different free software communities. The results show that learning and ease of access to knowledge influence knowledge collection; recognition, community support for knowledge sharing and knowledge collection influence knowledge donation; and professional reasons influence both knowledge collection and knowledge donation in the context of free software communities.",NA

However, in open-source software (OSS) development, stakeholders’ social interactions are often decentralized, iterative, and dynamic. Little is known about new requirements identification in OSS and the stakeholders’ organizational arrangements supporting such an activity. In this article, we investigate the theory of structural hole from the context of contributing new requirements in OSS projects. Structural hole theory suggests that stakeholders positioned in the structural holes in their social network are able to produce new ideas. In this study, we find that structural hole positions emerge in stakeholders’ social network and these positions are positively related to contributing a higher number of new requirements. We find that along with structural hole positions, stakeholders’ role is also an important part in identifying new requirements. We further observe that structural hole positions evolve over time, thereby identifying requirements to realize enriched features. Our work advances the fundamental understanding of the RE process in a decentralized environment and opens avenues for improved techniques supporting this process.",10.1145/2795235

In these settings, many occurring activities can be documented and have established them as learning environments. As knowledge exchange is proved to occur in FLOSS, the dynamic and free nature of participation poses a great challenge in understanding activities pertaining to Learning Processes. In this paper we raise this question and propose an ontology (called OntoLiFLOSS) in order to define terms and concepts that can explain learning activities taking place in these communities. The objective of this endeavor is to define in the simplest possible way a common definition of concepts and activities that can guide the identification of learning processes taking place among FLOSS members in any of the standard repositories such as mailing list, SVN, bug trackers and even discussion forums.",10.1007/978-3-319-15201-1\\_11

As nations increasingly rely on knowledge assets to grow, the adoption of OSS will have profound economic consequences. This paper identifies the mechanisms inherent to OSS production that help fuel innovation in knowledge-based economies. As a collaborative and open production model, OSS is conceptualized as a prototype of open innovation. Drawing on US employment projections for 2008-2018, the authors' analysis predicts OSS will have a positive impact on employment growth in well-paid salary jobs across multiple sectors of the US economy. OSS-related software development jobs are widely diffuse throughout the economy, help build a skilled labour force and offer wages significantly above the national average. OSS is thus believed to be a strong contributor to growth in high-value employment in the US. The authors also posit that, as industries are exposed to the benefits of OSS as a result of the broad diffusion of OSS-related jobs, open innovation processes outside software development may be adopted through a process of learning and imitation.",10.4018/978-1-4666-7230-7.ch029

Standard communication protocols facilitate interconnectivity between software components and assure interoperability between different stakeholders of these components. For electric grids, standards introduce an open Smart Grid for liberalized service-oriented electricity markets by smoothing the way for business interactions and trades. Many organizations such as IEC and IEEE are introducing their standard communication protocols for future smart power grids and their associated smart meters.

Despite recent advances in imaging techniques, the application of unbiased computational image analysis methods for morphodynamic quantification is rare. For example, manual analysis using kymographs is still commonplace, often caused by lack of access to user-friendly, automated tools. We now describe software designed for the automated quantification of cell migration and morphodynamics. Implemented as a plug-in for the open-source platform, ImageJ, ADAPT is capable of rapid, automated analysis of migration and membrane protrusions, together with associated fluorescently labeled proteins, across multiple cells. We demonstrate the ability of the software by quantifying variations in cell population migration rates on different extracellular matrices.

With the ever-increasing availability of genomic data, inference of orthology has become instrumental for generating hypotheses about gene functions crucial to many studies. This update of the OrthoDB hierarchical catalog of orthologs (http://www.orthodb.org) covers 3027 complete genomes, including the most comprehensive set of 87 arthropods, 61 vertebrates, 227 fungi and 2627 bacteria (sampling the most complete and representative genomes from over 11,000 available). In addition to the most extensive integration of functional annotations from UniProt, InterPro, GO, OMIM, model organism phenotypes and COG functional categories, OrthoDB uniquely provides evolutionary annotations including rates of ortholog sequence divergence, copy-number profiles, sibling groups and gene architectures. We re-designed the entirety of the OrthoDB website from the underlying technology to the user interface, enabling the user to specify species of interest and to select the relevant orthology level by the NCBI taxonomy.

Firms sponsoring OSS projects may face substantial challenges in soliciting such contributions, since volunteer participants are neither regulated by an employment contract nor offered financial incentives. Although prior work has shown the positive impact of motivation on the effort expended by volunteer participants, there is limited understanding of how specific firm attributes shape volunteers' intrinsic motivation. We offer a theoretical model of how the perceived community-based credibility and openness of the sponsoring firm have a positive impact on the intrinsic motivation of volunteer participants. The model is explored using survey data on volunteer participants from two sponsored OSS projects. Results show that a sponsoring firm's community-based credibility (OSS developers' perception of its expertise and trustworthiness) and openness (its mutual knowledge exchange with the community) strengthen the volunteer participants' social identification with the firm-sponsored community, which in turn reinforces their intrinsic motivation to participate. Moreover, the perceived community-based credibility of a sponsoring firm directly enhances volunteer participants' intrinsic motivation, whereas perceived openness fails to affect motivation without the mediating mechanism of social identification. Implications for firms seeking voluntary contributions for their sponsored OSS projects are discussed.",10.1287/isre.2014.0539

Design/methodology/approach - Two studies were carried out. In Study 1, a content analysis classifying OSS-related questions posted during December 2005-December 2012 in Yahoo! Answers was employed to investigate the general public's information needs regarding OSS. In Study 2, an online survey was conducted with OSS answerers in Yahoo! Answers in order to examine what motivates them to share and continue to share their knowledge of OSS in social Q\\&A. In total, 1,463 invitations were sent out via Yahoo! Answers' internal e-mail function to those who provided answers to OSS-related questions during September 2009-September 2012. In total, 150 usable surveys were returned and used for data analysis. Findings - The findings from Study 1 indicate that the general public is most interested in finding out if there is OSS that meets their software need in a certain category (51.4 percent). Other popular question categories include the general description of OSS (15.6 percent), technical issues that they have with OSS (9.8 percent), and the advantages/disadvantages of using OSS (7.0 percent). Results on OSS answerers' motivations from Study 2 support that all seven motivations identified (i.e. altruism, enjoyment, ideology, learning, reputation, reciprocity, and self-efficacy) are important, with the smallest mean value being 4.42 out of seven (i.e. reciprocity). However, only altruism, ideology, self-efficacy, and enjoyment were found to significantly influence contribution continuance intention. Practical implications - With social Q\\&A growing in popularity, OSS communities that look for ways to draw in more users from the general public are recommended to increase their presence in social Q\\&A. The findings with regard to OSS answerers' motivations can also help OSS community leaders attract and guide more members who are interested in sharing their OSS knowledge in social Q\\&A. Originality/value - By classifying OSS-related questions that are publicly available in Yahoo! Answers, this study offers a breakdown of the general public's information needs regarding OSS. In addition, results on OSS answerers' motivations suggest that in order to sustain their member contributions in social Q\\&A, OSS community leaders should pay more attention to nurturing the motivations that are intrinsic (i.e. altruism, self-efficacy, enjoyment) and integrated (i.e. ideology).",10.1108/OIR-06-2014-0139

In this paper, the drying characteristics of Calotropis gigantea pods on microwave radiation by using different drying methods, different microwave powers, and different time periods, are studied, and the corresponding impacts on fiber quality are analyzed. The experimental results show that obtaining Calotropis gigantea seed fibers by microwave heating the pods is feasible. Compared to natural air drying and hot air drying, the microwave drying (MW can significantly improve the drying efficiency and reduce the drying time by more than 5 times. The microwave power has considerable influences on the drying rate. However, the fiber strength and break elongation are reduced with the increase of microwave power due to fiber structural change caused by the high temperature inside the pod. Compared with intermittent radiation, the moisture loss rate of the pods is greater in continuous radiation mode, but the pod internal temperature is higher, which is harmful to the quality of the fibers. Varying power radiation, which uses lower power first, then higher, could shorten drying time without impeding the pods' abdominal suture broadening.",NA

The main users are biologists and related life scientists with no or little knowledge of image processing. In this review, we give an overview of available tools and guidelines about which tools the users should use to segment fluorescence micrographs. We selected 15 free tools and divided them into stand-alone, Matlab-based, ImageJ-based, free demo versions of commercial tools and data sharing tools. The review consists of two parts: First, we developed a criteria catalogue and rated the tools regarding structural requirements, functionality (flexibility, segmentation and image processing filters) and usability (documentation, data management, usability and visualization). Second, we performed an image processing case study with four representative fluorescence micrograph segmentation tasks with figure-ground and cell separation. The tools display a wide range of functionality and usability. In the image processing case study, we were able to perform figure-ground separation in all micrographs using mainly thresholding. Cell separation was not possible with most of the tools, because cell separation methods are provided only by a subset of the tools and are difficult to parametrize and to use. Most important is that the usability matches the functionality of a tool. To be usable, specialized tools with less functionality need to fulfill less usability criteria, whereas multipurpose tools need a well-structured menu and intuitive graphical user interface.",10.1111/jmi.12184

+1387,InProceedings,Social Network Analysis of Developers' and Users' Mailing Lists of Some Free Open Source Software,"As reported by Kevin Crowston and co-authors in a recent paper, free open source software is a very important social phenomenon that involves nearly one million programmers, a myriad of software development firms, millions of users, and its financial impact is huge since for instance the cost of recreating available free software is estimated in tens of billions of euros. Free open source software projects generally have one mailing list for developers and another one for users. This large number of mailing lists changes constantly and shows a great variety with respect to membership and topics covered. This makes them very difficult to monitor. One way of overcoming this Big Data Challenge is to identify some easily computable global indicators that can be used for instance to detect important events. We illustrate this approach here by making a social network analysis and comparison of developers' and users' mailing lists of four free open source software projects: CentOS, GnuPG, Mailman and Samba. We show that these mailing lists have some common characteristics: the number of messages, the time durations and the interlink times can be fitted using power and lognormal laws with suitable scales and parameters, for the interlink time, the analysis is done using the temporal delta density inspired by the delta density introduced by Viard and Latapy. This similarity between the characteristics of mailing lists also applies to the structure of dominant groups. For the time evolution of the number of messages, GnuPG exhibits a particular behavior. The interpretation of the different parameters gives very interesting insights into the membership and the type of topics covered by the mailing lists. The analysis carried out here and similar studies cited in this paper can therefore be considered as a first step towards the designing of building blocks for monitoring mailing lists.",10.1109/BigDataCongress.2015.119

Four deep cases are analyzed to develop a conceptual framework based on within-case and cross-case analysis. In terms of data collection, online (including skype meeting, email, email-list, IRC, forum, group meeting, etc) and offline (mainly with face-to-face discussion) activities are two major platforms. The research framework is that distributed innovation (independent variable) will influence shared knowledge (medium variable) and continue to affect the performance of OSS projects (dependent variable). During distributed innovation, developers located on the supply side will affect the shared knowledge from the aspects of Participative Motivation, Social Network and Organizational Culture. Meanwhile, users situated on the demand side will function from the view of user innovation.",NA
+1394,InProceedings,Surveying the Adoption of FLOSS by Public Administration Local Organizations,"Background. The introduction of Open Source Software technologies in the Public Administration plays a key role in the spread of Open Source Software. The state of the art in the adoption of Open Source Software solutions in the Public Administration is not very well known even in areas like Lombardy, which is Italy's largest and most developed region. Goal. The goal of the investigation documented in this paper is to obtain a clear picture about the introduction of Open Source Software technologies in the Public Administration, the obstacles to their adoption, and the willingness of stakeholders to proceed with their introduction. Method. We carried out a qualitative and quantitative survey that was submitted to a representative part of the Public Administrations in Lombardy. Results. The analysis of the qualitative and quantitative information shows that several Public Administrations are already using Open Source Software technologies, though not in all application areas. The savings are one frequently cited incentive to the adoption of Open Source Software. However, one obstacle is the fact that a comprehensive law on software in the Public Administration has not yet been approved. Conclusions. Our analysis provides results that indicate a common understanding of incentives, obstacles, and opportunities for Open Source Software technologies in Public Administrations.",10.1007/978-3-319-17837-0\\_11
+1395,Article,Sustainability and social responsibility reporting in open source software,"Digital commons have held the interest of the research community in recent years. However, institutional recognition has not been fully awarded mainly due to the absence of a comprehensive reporting framework. The objective of our research is to identify indicators in order to measure open source projects performance. Motivation that led us to carry out this analysis was the fact that, despite the many benefits attributed to open sourcing, no information about it was disclosed on annual reports. We are based on previous literature about creating institutions to governing the commons. One of the key goals is institutional reporting to members of the community, so we believe that a reporting model based on social responsibility framework is clearly suitable for this purpose. Social responsibility and sustainability are about enabling organizations to incorporate creation of social, environmental and economic value into core strategy and operations; their reporting is key to create value for organizations, their stakeholders and society as a whole. To reach our goal, we asked a panel of open source experts their opinion about the key success factors and other relevant variables for the purpose of recommending a methodology to calculate specific indicators to be disclosed on social responsibility reports.",NA

We argue that progress has been impeded by the fact that software has not been developed and shared as a community. Recently, the situation has been changing. In this paper, the developers of a number of open-source software (OSS) projects highlight the potential of OSS to advance radar-related research. We argue that the community-based development of OSS holds the potential to reduce duplication of efforts and to create transparency in implemented algorithms while improving the quality and scope of the software. We also conclude that there is sufficiently mature technology to support collaboration across different software projects. This could allow for consolidation toward a set of interoperable software platforms, each designed to accommodate very specific user requirements.",10.1175/BAMS-D-13-00240.1

+1402,Article,Testing the water: detecting artificial water points using freely available satellite data and open source software,"Deserts are among the most poorly understood biomes in the world, currently experiencing among the highest rates of environmental change and biodiversity loss. A major controlling factor on the ecology and distribution of vegetation and animal populations in these harsh arid systems is the abundance and distribution of water sources. Accordingly, extraction and redistribution of water at artificial water points across desert landscapes can constitute a real threat to local ecosystem dynamics. A major challenge in tackling this potential threat is identifying changes in the distribution of artificial water points through space and time, due to the difficulties of collecting such information at relevant spatial and temporal scales. We here investigate the potential for freely available satellite imagery to provide reliable information about the distribution of artificial water points using the Ouadi Rime-Ouadi Achim Faunal Reserve (OROAFR), Chad, as a case study. We reveal that Landsat 8 data combined with texture analysis can accurately detect these artificial landmarks across the heterogeneous environment of OROAFR; 75.68\\% of artificial water points within the site were successfully identified and false positive detection rate was minimal at 7.69\\%. The methodological framework developed for this work, based on the treatment of freely available satellite data using open source software, adds to other works attempting to help monitor threats to biodiversity in desert ecosystems, enabling up-to-date information on the level of anthropogenic activities in these habitats to be easily and regularly collected.",10.1002/rse2.5

We then compare the rate at which software developers decided whether to accept or reject the new pastebin tools. We find that the overall rate of pastebin adoption follows the S-curve predicted by classic DoI theory. We then compare the individual pastebin services and their rates of adoption, as well as the reaction of different communities to the new tools and the various rationales for accepting or rejecting them.",10.1007/978-3-319-17837-0\\_5

Despite the immense success of several mainstream OSS projects such as Mozilla, Linux, and Apache, a vast majority of such projects fail to sustain their development due to high levels of developer turnover. While existing research in the area has offered a rich foundation, we know little about how developers' perceptions of fit with the project environment may be moderated by the sense of ownership they have toward the project and how it may impact their turnover intentions. Using survey data from 574 GitHub developers, we tested a model to examine the impact of Person-Organization fit and psychological ownership on developers' turnover intentions. Our results suggest that two relevant dimensions of fit, namely, value and demands-abilities fit, negatively impact turnover intentions and that their sense of ownership moderates these effects.",NA

Biologists developed and adopted technologies of the nascent World Wide Web and Free and Open Source Software (FOSS) communities for sharing biological information. These technologies supported decentralized, collaborative, and nonproprietary modes of production in biology. Such technologies were appealing not merely because they were expedient for genomic work but because they also offered a way of promoting a particular form of genomic practice. As the genome sequencing centers scaled up their sharing efforts, a small group of computer-savvy biologists used these tools to promote the interests of the public genome sequencing effort.

This large amount of data hampers people to make sense of implicit links between software projects, e.g., dependencies, patterns, licenses. This context raises the question of what techniques and mechanisms can be used to help users and developers to link related pieces of information across software projects. In this paper, we propose a framework for a marketplace enhanced using linked open data (LOD) technology for linking software artifacts within projects as well as across software projects. The marketplace provides the infrastructure for collecting and aggregating software engineering data as well as developing services for mining, statistics, analytics and visualization of software data. Based on cross-linking software artifacts and projects, the marketplace enables developers and users to understand the individual value of components and their relationship to bigger software systems. Improved understanding creates new business opportunities for software companies: users will be able to analyze and compare projects, developers can increase the visibility of their products, and hosts may offer plugins and services over the data to paying customers.",10.1109/HICSS.2015.439

Therefore, knowing the impact of different OSS adoption strategies in the context of an organization may help improving the processes undertaken inside this organization and ultimately pave the road to strategic moves. However, there is a lack of support for assessing the impact of the OSS adoption over the business of the adopter organizations. Based on the goal-oriented characterization of some OSS adoption strategies, in this paper, we propose a preliminary approach to assess the business impact of the OSS adoption strategies over the adopter organizations.

Usually these communities do not coordinate the work of the newcomers, who go to the issue trackers and self-select a task to start with. We found that ``finding a way to start{''} was reported as an important issue by practitioners. To further investigate this specific barrier, we conducted a qualitative analysis with data obtained from semi-structured interviews with 36 subjects from 14 different projects, including newcomers and experienced members. We used procedures of Grounded Theory-open and axial coding-to analyze the data. We found that newcomers are not confident enough to choose their initial task and they need information about the tasks or direction from the community to support choosing a task more suitable for them.

The naturally evolving structure of collaborative relationships among software developers is a major distinction between the OSS development model and the traditional development model. Conventional statistical methods that focus on individual cases and their attributes cannot properly inform the management of the naturally evolving collaborative relationships in open source project. We emphasize social network analysis as a method especially suitable for management of open source development projects, because it focuses on relations among individuals rather than attributes of individual cases. We show how open source development can be represented as a collaboration network graph and how the network can be characterized by various network structure metrics. We present four metrics as a starting point size, centralization, density and clusterness; that are most useful in revealing collaborative relationships in OSS development process. We discuss how to generate collaboration network for OSS projects and how to calculate the metrics.

Modeling Participant's Initial Behavior,"Motivation: To survive and succeed, FLOSS projects need contributors able to accomplish critical project tasks. However, such tasks require extensive project experience of long term contributors (LTCs). Aim: We measure, understand, and predict how the newcomers' involvement and environment in the issue tracking system (ITS) affect their odds of becoming an LTC. Method: ITS data of Mozilla and Gnome, literature, interviews, and online documents were used to design measures of involvement and environment. A logistic regression model was used to explain and predict contributor's odds of becoming an LTC. We also reproduced the results on new data provided by Mozilla. Results: We constructed nine measures of involvement and environment based on events recorded in an ITS. Macro-climate is the overall project environment while micro-climate is person-specific and varies among the participants. Newcomers who are able to get at least one issue reported in the first month to be fixed, doubled their odds of becoming an LTC. The macro-climate with high project popularity and the micro-climate with low attention from peers reduced the odds. The precision of LTC prediction was 38 times higher than for a random predictor. We were able to reproduce the results with new Mozilla data without losing the significance or predictive power of the previously published model. We encountered unexpected changes in some attributes and suggest ways to make analysis of ITS data more reproducible. Conclusions: The findings suggest the importance of initial behaviors and experiences of new participants and outline empirically-based approaches to help the communities with the recruitment of contributors for long-term participation and to help the participants contribute more effectively.

+1438,Article,adLIMS: a customized open source software that allows bridging clinical and basic molecular research studies,"Background: Many biological laboratories that deal with genomic samples are facing the problem of sample tracking, both for pure laboratory management and for efficiency. Our laboratory exploits PCR techniques and Next Generation Sequencing (NGS) methods to perform high-throughput integration site monitoring in different clinical trials and scientific projects. Because of the huge amount of samples that we process every year, which result in hundreds of millions of sequencing reads, we need to standardize data management and tracking systems, building up a scalable and flexible structure with web-based interfaces, which are usually called Laboratory Information Management System (LIMS). Methods: We started collecting end-users' requirements, composed of desired functionalities of the system and Graphical User Interfaces (GUI), and then we evaluated available tools that could address our requirements, spanning from pure LIMS to Content Management Systems (CMS) up to enterprise information systems. Our analysis identified ADempiere ERP, an open source Enterprise Resource Planning written in Java J2EE, as the best software that also natively implements some highly desirable technological advances, such as the high usability and modularity that grants high use-case flexibility and software scalability for custom solutions. Results: We extended and customized ADempiere ERP to fulfil LIMS requirements and we developed adLIMS. It has been validated by our end-users verifying functionalities and GUIs through test cases for PCRs samples and pre-sequencing data and it is currently in use in our laboratories. adLIMS implements authorization and authentication policies, allowing multiple users management and roles definition that enables specific permissions, operations and data views to each user. For example, adLIMS allows creating sample sheets from stored data using available exporting operations. This simplicity and process standardization may avoid manual errors and information backtracking, features that are not granted using track recording on files or spreadsheets. Conclusions: adLIMS aims to combine sample tracking and data reporting features with higher accessibility and usability of GUIs, thus allowing time to be saved on doing repetitive laboratory tasks, and reducing errors with respect to manual data collection methods. Moreover, adLIMS implements automated data entry, exploiting sample data multiplexing and parallel/transactional processing. adLIMS is natively extensible to cope with laboratory automation through platform-dependent API interfaces, and could be extended to genomic facilities due to the ERP functionalities.",10.1186/1471-2105-16-S9-S5
+1439,Article,sfDM: Open-Source Software for Temporal Analysis and Visualization of Brain Tumor Diffusion MR Using Serial Functional Diffusion Mapping,"A major challenge in the diagnosis and treatment of brain tumors is tissue heterogeneity leading to mixed treatment response. Additionally, they are often difficult or at very high risk for biopsy, further hindering the clinical management process. To overcome this, novel advanced imaging methods are increasingly being adapted clinically to identify useful noninvasive biomarkers capable of disease stage characterization and treatment response prediction. One promising technique is called functional diffusion mapping (fDM), which uses diffusion-weighted imaging (DWI) to generate parametric maps between two imaging time points in order to identify significant voxel-wise changes in water diffusion within the tumor tissue. Here we introduce serial functional diffusion mapping (sfDM), an extension of existing fDM methods, to analyze the entire tumor diffusion profile along the temporal course of the disease. sfDM provides the tools necessary to analyze a tumor data set in the context of spatiotemporal parametric mapping: the image registration pipeline, biomarker extraction, and visualization tools. We present the general workflow of the pipeline, along with a typical use case for the software. sfDM is written in Python and is freely available as an open-source package under the Berkley Software Distribution (BSD) license to promote transparency and reproducibility.",10.4137/CIN.S17293

Through a properly parameterized model we are able to do inference on mixture proportions, the peak height properties, stutter proportion and degradation. In addition, EuroForMix includes models for allele drop-out, allele drop-in and sub-population structure. EuroForMix supports two inference approaches for likelihood ratio calculations. The first approach uses maximum likelihood estimation of the unknown parameters. The second approach is Bayesian based which requires prior distributions to be specified for the parameters involved. The user may specify any number of known and unknown contributors in the model, however we find that there is a practical computing time limit which restricts the model to a maximum of four unknown contributors. EuroForMix is the first freely open source, continuous model (accommodating peak height, stutter, drop-in, drop-out, population substructure and degradation), to be reported in the literature. It therefore serves an important purpose to act as an unrestricted platform to compare different solutions that are available. The implementation of the continuous model used in the software showed close to identical results to the R-package DNAmixtures, which requires a HUGIN Expert license to be used. An additional feature in EuroForMix is the ability for the user to adapt the Bayesian inference framework by incorporating their own prior information. (C) 2015 Elsevier Ireland Ltd.

+1442,Article,Marathon: An Open Source Software Library for the Analysis of Markov-Chain Monte Carlo Algorithms,"We present the software library marathon, which is designed to support the analysis of sampling algorithms that are based on the Markov-Chain Monte Carlo principle. The main application of this library is the computation of properties of so-called state graphs, which represent the structure of Markov chains. We demonstrate applications and the usefulness of marathon by investigating the quality of several bounding methods on four well-known Markov chains for sampling perfect matchings and bipartite graphs. In a set of experiments, we compute the total mixing time and several of its bounds for a large number of input instances. We find that the upper bound gained by the famous canonical path method is often several magnitudes larger than the total mixing time and deteriorates with growing input size. In contrast, the spectral bound is found to be a precise approximation of the total mixing time.",10.1371/journal.pone.0147935

Efficient maintenance within short release cycles depends highly on the underlying source code structure, in the sense that complex modules are more difficult to maintain. In this paper we attempt to unveil and discuss relationships between maintenance productivity, the structural quality of the source code and process metrics like the type of a release and the number of downloads. To achieve this goal, we developed a Bayesian Belief Network (BBN) involving several maintainability predictors and three managerial indices for maintenance (i.e., duration, production, and productivity) on 20 open source software projects. The results suggest that maintenance duration depends on inheritance, coupling, and process metrics. On the other hand maintenance production and productivity depend mostly on code quality metrics.",10.1007/978-3-319-39225-7\\_3
+1445,InProceedings,A FLOSS License-selection Methodology for Cloud Computing Projects,"Cloud computing and open source are two disruptive innovations. Both deeply modify the way the computer resources are made available and monetized. They evolve between competition (e.g. open source software for desktop versus SaaS applications) and complementarity (e.g. cloud solutions based on open source components or cloud applications published under open source license). PaaSage is an open source integrated platform to support both design and deployment of cloud applications. The PaaSage consortium decided to publish the source code as open source. It needed a process for the open source license selection. Open source licensing scheme born before the development of cloud computing and evolved with the creation of new open source licenses suitable for SaaS applications. The license is a part of project governance and strongly influences the life of the project. In the context of the PaaSage European project, the issue of the open source license selection for cloud computing software has been addressed. The first section of the paper describes the state of the art about open source licenses including the known issues, a generic license-selection scheme and the automated source code analysis practices. The second section studies the common choices of licenses in cloud computing projects. The third section proposes a FLOSS license-selection process for cloud computing project following five steps: (1) inventoring software components, (2) selecting open source license, (3) approving license selection (vote), (4) spreading practical details and (5) monitoring source code. The fourth section describes the PaaSage use case. The last section consists in a discussion of the results.",10.5220/0005775901290136

On the other hand, an effective method of quality management has not been established due to the unique development characteristics such as no testing phase. In this paper, we assume that the number of fault-detections observed on the bug tracking system tends to infinity, and discuss a method of statistical process control (SPC) for OSS projects by applying the logarithmic Poisson execution time model as a software reliability growth model (SRGM) based on a nonhomogeneous Poisson process (NHPP). Then, we propose a control chart method based on the logarithmic Poisson execution time model for judging the statical stability state, and estimating the additional development time for attaining the objective software failure intensity, i.e., the target value of the instantaneous fault-detection rate per unit time. We also discuss an optimal software release problem for determining the optimum time when to stop OSS development and to transfer it to user operation. Further, numerical illustrations for SPC are shown by applying the actual fault-count data observed on the bug tracking system.",10.1142/S0218539316500182
+1450,InProceedings,A Research Proposal: Tracking Open Source Software Evolution for the Characterization of Its Evolutionary Behavior,"Open Source Software (OSS) has attracted a lot of attention in the last decade. Due to the rising dominance of OSS in the software industry; not only practitioners, but researchers as well as academicians are also keen to understand the OSS development and evolution process. Several studies have been conducted in the past in this regard. Most of the existing work relates to growth analysis of OSS projects using source code level metrics. Lately, metrics related to change activity have also been included to understand OSS evolution. Change activity as recorded in Source Code Management (SCM) systems is used in a few cases. Most of the work deals with finding change size, and change effort distributions. A few studies do change profile analysis as OSS systems evolve. But that is restricted to a few of the change categories, e.g., adaptive v/s non-adaptive changes, corrective v/s non-corrective changes. This research study explores change profiles of 106 OSS systems by extracting change type information from their SCM repositories and then categorizing these changes automatically into five different categories - corrective, adaptive, perfective, preventive, and enhancement related. The idea is to understand the way OSS projects undergo change through long periods of time. The results indicate that change behavior of the OSS projects is different for different types of changes.",10.1007/978-3-319-49094-6\\_63

Over the time, several modifications of the method for fuzzy environment have been devised. The paper introduces a new free software tool that implements one of these approaches. The elements of the pair-wise comparison matrix are allowed to be expressed by triangular fuzzy elements. The classical non-fuzzy methods based on the eigenvectors or the geometric means are also supported in the software. The presented software has been written as a web application, which means that it is available from any computer connected to the Internet without need to install any additional software.

This paper describes a recipe for the design, development, and deployment of a low-cost environmental data logging and transmission system for environmental sensors and its connection to an open source data-sharing network. The hardware is built using several low-cost, open-source, mass-produced components. The system automatically ingests data into HydroServer, a standards-based server in the open source hydrologic information system (HIS) created by the Consortium of Universities for the Advancement of Hydrologic Sciences Inc.

+1453,Article,A tightly coupled scheme for neutronics and thermal-hydraulics using open-source software,"Coupling neutronic and thermal-hydraulic analyses of a nuclear reactor core is important because it helps identify the most relevant safety issues without conservative assumptions. Currently coupled computations solve the same governing equations using different coupling methods, which can be sorted into two categories: loose coupling and tight coupling. This paper proposes and verifies a third coupling approach called ``the Integrated Tight Coupling (ITC) method{''}. The mathematical equations in the nuclear fuel are rearranged to be integrated via a novel concept of the energy-group function. In addition, the data from the neutron cross section library can be used directly. The ITC method is implemented using two open-source codes: the DRAGON code and OpenFOAM. Additionally, a coupled computation using these two codes is new and has not been done. The ITC method is verified using a 1.5-D (1-D neutronics and 2-D thermal-hydraulics) symmetric unit cell example. The mesh of the tightly integrated computation is 25\\% coarser than the loosely coupled one. Starting from a similar initial guess, the number of iterations for the ITC method is 24\\% fewer than that for the loosely coupled computation to reach the same accuracy. In addition, the ITC method is tested with different initial guesses. For all cases tested, the scheme converged to the same solution. With further improvement and additional testing, the ITC method has the potential to be incorporated with other neutronics and thermal-hydraulics codes. (C) 2015 Elsevier Ltd.

Free software is the best choice when the reduction of production costs is necessary; nevertheless, the quality of free software may vary. This paper probably does not include all of the free software, but tries to describe or mention at least the most interesting programs. The first part of this paper summarizes the essential knowledge about UAVs, including the fundamentals of flight mechanics and aerodynamics, and the structure of a UAV system. The second section generally explains the modelling and simulation of a UAV. In the main section, more than 50 free programs for the design, analysis, modelling, and simulation of a UAV are described. Although the selection of the free software has been focused on small subsonic UAVs, the software can also be used for other categories of aircraft in some cases; e.g. for MAVs and large gliders. The applications with an historical importance are also included. Finally, the results of the analysis are evaluated and discussed--a block diagram of the free software is presented, possible connections between the programs are outlined, and future improvements of the free software are suggested.",10.1007/s11831-015-9147-y
+1455,InProceedings,AEROSTACK: An Architecture and Open-Source Software Framework for Aerial Robotics,"To simplify the usage of the Unmanned Aerial Systems (UAS), extending their use to a great number of applications, fully autonomous operation is needed. There are many open-source architecture frameworks for UAS that claim the autonomous operation of UAS, but they still have two main open issues: (1) level of autonomy, being in most of the cases limited and (2) versatility, being most of them designed specifically for some applications or aerial platforms. As a response to these needs and issues, this paper presents Aerostack, a system architecture and open-source multi-purpose software framework for autonomous multi-UAS operation. To provide higher degrees of autonomy, Aerostack's system architecture integrates state of the art concepts of intelligent, cognitive and social robotics, based on five layers: reactive, executive, deliberative, reflective, and social. To be a highly versatile practical solution, Aerostack's open-source software framework includes the main components to execute the architecture for fully autonomous missions of swarms of UAS; a collection of ready-to-use and flight proven modular components that can be reused by the users and developers; and compatibility with five well known aerial platforms, as well as a high number of sensors. Aerostack has been validated during three years by its successful use on many research projects, international competitions and exhibitions. To corroborate this fact, this paper also presents Aerostack carrying out a fictional fully autonomous indoors search and rescue mission.",NA

The aim of our research is to adopt the Personas usability technique in the PSeInt OSS project and determine the feasibility of adapting the technique for application. To do this, we participated as volunteers in the project. We used the case study research method during technique application and participation in the community. As a result, we identified adverse conditions that were an obstacle to technique application and modified the technique to make it applicable. We can conclude from our experience that these changes were helpful for applying the technique, although it was not easy to recruit OSS users to participate in usability technique application.",10.1145/2998626.2998653

+1460,Article,An empirical examination of the prevalence of inhibitors to the parallelizability of open source software systems,"An empirical study is presented that examines the potential to parallelize general-purpose software systems. The study is conducted on 13 open source systems comprising over 14 MLOC. Each for-loop is statically analyzed to determine if it can be parallelized or not. A for-loop that can be parallelized is termed a free-loop. Free-loops can be easily parallelized using tools such as OpenMP. For the loops that cannot be parallelized, the various inhibitors to parallelization are determined and tabulated. The data shows that the most prevalent inhibitor by far, is functions called within for-loops that have side effects. This single inhibitor poses the greatest challenge in adapting and re-engineering systems to better utilize modern multi-core architectures. This fact is somewhat contradictory to the literature, which is primarily focused on the removal of data dependencies within loops. Results of this paper also show that function calls via function pointers and virtual methods have very little impact on the for-loop parallelization process. Historical data over a 10-year period of inhibitor counts for the set of systems studied is also presented. It shows that there is little change in the potential for parallelization of loops over time.",10.1007/s10664-015-9385-5
+1461,Article,An empirical study of integration activities in distributions of open source software,"Reuse of software components, either closed or open source, is considered to be one of the most important best practices in software engineering, since it reduces development cost and improves software quality. However, since reused components are (by definition) generic, they need to be customized and integrated into a specific system before they can be useful. Since this integration is system-specific, the integration effort is non-negligible and increases maintenance costs, especially if more than one component needs to be integrated. This paper performs an empirical study of multi-component integration in the context of three successful open source distributions (Debian, Ubuntu and FreeBSD). Such distributions integrate thousands of open source components with an operating system kernel to deliver a coherent software product to millions of users worldwide. We empirically identified seven major integration activities performed by the maintainers of these distributions, documented how these activities are being performed by the maintainers, then evaluated and refined the identified activities with input from six maintainers of the three studied distributions. The documented activities provide a common vocabulary for component integration in open source distributions and outline a roadmap for future research on software integration.",10.1007/s10664-015-9371-y

However, even after 20 years of intense research in this field, perfusion imaging still remains a research tool without a broad clinical usage. One problem is the lack of standardization in technical aspects which have to be considered for successful quantitative evaluation; the second problem is a lack of tools that allow a direct integration into the diagnostic workflow in radiology. Results: Five compartment models, namely, a one compartment model (1CP), a two compartment exchange (2CXM), a two compartment uptake model (2CUM), a two compartment filtration model (2FM) and eventually the extended Toft's model (ETM) were implemented as plugin for the DICOM workstation OsiriX. Moreover, the plugin has a clean graphical user interface and provides means for quality management during the perfusion data analysis. Based on reference test data, the implementation was validated against a reference implementation. No differences were found in the calculated parameters. Conclusion: We developed open source software to analyse DCE-MRI perfusion data. The software is designed as plugin for the DICOM Workstation OsiriX. It features a clean GUI and provides a simple workflow for data analysis while it could also be seen as a toolbox providing an implementation of several recent compartment models to be applied in research tasks.

+1468,InProceedings,Attributes of Open Source Software Requirements - The Effect of the External Environment and Internal Social Structure,Popularity of open source software (OSS) projects has spiked an interest in the requirements engineering (RE) practices of such communities that are starkly different from those in traditional software development projects. Past work has focused on characterizing the main differences between OSS and traditional forms of software RE. In this effort we focus on differences in RE activity in OSS. RE is characterized as a socio-technical distributed cognitive (DCog) activity where multiple actors deploy artifacts to `compute' requirements. To uncover how OSS projects configure the socio-technical distribution of cognitive processes to respond to varying attributes of incoming requirements we conduct a comparative analysis of four successful OSS projects. We observe that the volume of requirements faced by an OSS group dictates largely the nature of its social formation while the volatility experienced in the requirements dictates the overlap the project exhibits with the larger external community. Finally the velocity of change in technological requirements influence the project's documentation practices of requirements with the level of design consistency desired in the end product influencing the decision-making channels used in the development endeavor.,10.1109/HICSS.2016.618

While several software packages have been proposed, their interface is sometimes limited and/or they are designed to work with a specific modality (e.g., scanning electron microscopy (SEM) only). Here we introduce AxonSeg, which allows to perform automatic axon and myelin segmentation on histology images, and to extract relevant morphometric information, such as axon diameter distribution, axon density and the myelin g-ratio. AxonSeg includes a simple and intuitive MATLABbased graphical user interface (GUI) and can easily be adapted to a variety of imaging modalities. The main steps of AxonSeg consist of: (i) image pre-processing; (ii) pre-segmentation of axons over a cropped image and discriminant analysis (DA) to select the best parameters based on axon shape and intensity information; (iii) automatic axon and myelin segmentation over the full image; and (iv) atlas-based statistics to extract morphometric information. Segmentation results from standard optical microscopy (OM), SEM and coherent anti-Stokes Raman scattering (CARS) microscopy are presented, along with validation against manual segmentations. Being fully-automatic after a quick manual intervention on a cropped image, we believe AxonSeg will be useful to researchers interested in large throughput histology.",10.3389/fninf.2016.00037
+1472,Article,BENCHMARKING FRAMEWORK FOR MAINTAIN ABILITY PREDICTION OF OPEN SOURCE SOFTWARE USING OBJECT ORIENTED METRICS,"Software maintainability is measured as the ease with which the existing software could be modified and often predicted during the development stage on the basis of some measurable design characteristics. Controlling the software maintainability and understandability of any open source software (OSS) system is extremely challenging because it is written and constantly modified by the developers located all over the world. The current study analyzes the effectiveness of machine learning (ML) techniques for the maintainability prediction of OSS systems. In this work large-scale empirical comparisons of thirteen classifiers over seven open source datasets were conducted followed by extensive statistical tests and post hoc analysis to establish the confidence on the performance of one ML technique over another. The results show two important findings: firstly, we observed that overall good prediction accuracy is achieved by almost all ML techniques; secondly the prediction models using genetically adaptive learning ML technique and group method of data handling (GMDH) technique perform better than the other ML techniques in the context of OSS systems. The outcome of this investigation would be helpful for developers in order to predict maintenance behavior of the software at the earlier stages of software development lifecycle (SDLC). Accordingly, they can optimize their resource allocations, prioritize maintenance tasks and produce high-quality low maintenance software systems. Additionally, it also has numerous other applications such as schedule planning, cost estimation, quality assurance testing, software debugging, budget preparation, and software performance optimization.",NA

The use of OSS does not harm security; on the contrary, it enhances it. Even with some drawbacks, OSS is highly reliable and maintained by a huge software community, thus decreasing implementation costs and increasing reliability. Moreover, it allows military software engineers to move away from proprietary applications and single-vendor contracts. Furthermore, it decreases the cost of long-term development and lifecycle management, besides avoiding vendor's lock in. Nevertheless, deploying OSS deserves an appropriate organization of its life cycle and maintenance, which has a relevant impact on the project's budget that cannot be overseen. In this paper, we will describe some of the major trends in OSS in Defense environments. The community for OSS has a pivotal role, since it is the core development unit. With Agile and the newest DevOps methodologies, government officials could leverage OSS capabilities, decreasing the Design (or Technical) Debt.

In specific, firm-sponsored developers may face identification conflicts arising from different social norms and beliefs inherent in both the organizational culture of their employing company and dominant OSS cultures. These conflicts may induce developer turnover intention towards the organization and the OSS community. This research seeks to identify identification-related determinants that drive turnover intention by surveying Linux kernel developers (N = 321).

+1476,Article,BluePyOpt: Leveraging Open Source Software and Cloud Infrastructure to Optimise Model Parameters in Neuroscience,"At many scales in neuroscience, appropriate mathematical models take the form of complex dynamical systems. Parametrising such models to conform to the multitude of available experimental constraints is a global nonlinear optimisation problem with a complex fitness landscape, requiring numerical techniques to find suitable approximate solutions. Stochastic optimisation approaches, such as evolutionary algorithms, have been shown to be effective, but often the setting up of such optimisations and the choice of a specific search algorithm and its parameters is non-trivial, requiring domain-specific expertise. Here we describe BluePyOpt, a Python package targeted at the broad neuroscience community to simplify this task. BluePyOpt is an extensible framework for data-driven model parameter optimisation that wraps and standardises several existing open-source tools. It simplifies the task of creating and sharing these optimisations, and the associated techniques and knowledge. This is achieved by abstracting the optimisation and evaluation tasks into various reusable and flexible discrete elements according to established best-practices. Further, BluePyOpt provides methods for setting up both small- and large-scale optimisations on a variety of platforms, ranging from laptops to Linux clusters and cloud-based compute infrastructures. The versatility of the BluePyOpt framework is demonstrated by working through three representative neuroscience specific use cases",10.3389/fninf.2016.00017

This free collaboration gathers globally distributed teams. Similarly, it is common today to view businesses and other human organisations as ecosystems, where several participating companies and organisations cooperate and compete together. As an example, Free/Libre Open Source Software ( FLOSS) development is one area where community driven development provides a plausible platform for both development of products and establishing a software ecosystem where a set of businesses contribute their own innovations. Equally, open and informal learning environments and open innovation platforms are also gaining ground. While such initiatives are not limited to any specific area, they typically offer a technological, legal, social, and economic framework for development, relying always on people as open development would not exist without the active participation of them. This paper explores the participation of master students in FLOSS projects, while merging two different settings of learning: formal and open/informal education.",NA

In a society based on a federal structure and the principle of subsidiarity, it is almost natural to demand a vivid community with active citizens. Today, with the advent of social media and the new channels of communication, the question is how to leverage the benefits of this concept for local issues. More precise: How can the competence of the citizens be activated to make conditions of living in the neighbourhoods more attractive? In this paper, we discuss technical requirements for an open government. The SAGA standard of the Federal German Government strongly supports the notion of open-source software. With OpenSAGA, we introduce a new, performant and SAGA-compliant framework for the implementation of web applications for e-Government.

Though the hardware systems have advanced a lot in-terms of energy efficiency and computing power, the software's energy and resources efficiency is still lacking behind. In many cases due to poor/bad designing of software it cannot utilize the hardware efficiently and end up a system with high energy consumption. To address this issues software's need a careful profiling in its development process to make the software efficient and less resource hungry. In this paper we compared some of the profiling tools available as Free and Open Source Software (FOSS) which are used under Linux environment. These software tools uses different strategies and have different accuracies in finding a system and software programs behavior and its resource requirements. Their performance and resource overheads such as memory, CPU, disk consumption were compared and results are summarized for making the tools selection easier to researchers and developers alike.

+1489,Article,Coordinating Interdependencies in Online Communities: A Study of an Open Source Software Project,"To manage work interdependencies, online communities draw on a variety of arm's length coordination mechanisms offered by information technology platforms and associated practices. However, ``unresolved interdependencies{''} remain that cannot be addressed by such arm's length mechanisms. These interdependencies reflect, for example, unidentified or emerging knowledge-based dependencies between the community members or unaccounted relationships between ongoing community tasks. At the same time, online communities cannot resort to hierarchical coordination mechanisms such as incentives or command structures to address such interdependencies. So, how do they manage such interdependencies? To address this question, we conduct an exploratory, theory-generating case study involving qualitative and computational analyses of development activities within an open source software community: Rubinius. We analyze the ongoing management of interdependencies within the community and find that unresolved interdependencies are associated with alternatively structured sequences of activities, which we define as routines. In particular, we observe that two distinct classes of interdependencies-development and developer interdependencies-are associated with alternative forms of routine variation. We identify two generalized routine components-direct implementation and knowledge integration, which address these two distinct classes of unresolved interdependencies. In particular, direct implementation deals with development interdependencies within the code that are not already coordinated through modular interfaces, while knowledge integration resolves unaccounted interdependencies between developers. We conclude with implications for research into organizing principles for online communities and note the significance of our findings for the study of coordination in organization studies in general.",10.1287/isre.2016.0673

+1492,Article,"DEPLOYING SDN AND NFV AT THE SPEED OF INNOVATION: TOWARD A NEW BOND BETWEEN STANDARDS DEVELOPMENT ORGANIZATIONS, INDUSTRY FORA, AND OPEN-SOURCE SOFTWARE PROJECTS","Standards development organizations (SDOs) exist to assure the development of consensus-based, quality standards. These formal standards are needed in the telecommunications market to achieve functional interoperability. The standardization process takes years, and then a vendor still needs to implement the resulting standard in a product. This prevents service providers (SPs) who are willing to venture into new domains from doing so at a fast pace. With the development of software-defined networking (SDN) and network function virtualization (NFV), opensource technology is emerging as a new option in the telecommunications market. In contrast to SDOs, open-source software (OSS) communities create a product that may implicitly define a de-facto standard based on market consensus. Therefore, SPs are drawn to OSS, but they face technical, procedural, legal, and cultural challenges due to their lack of experience with open software development. The question therefore arises, how the interaction between OSS communities, SDOs, and industry fora (IF) can be organized to tackle these challenges. This article examines the evolving roles of OSS communities, IF, and SDOs, and places them in an NFV/SDN context. It sketches the differences between these roles and provides guidelines on how the interaction between them can turn into a mutually beneficial relationship that balances the conflicting goals of timely development on the one hand and technical excellence, openness, and fairness on the other, to reach their common goal of creating flexible and efficient telecommunications networks.",10.1109/MCOM.2016.7432171

Software managers and developers use several measures to measure and improve the quality of a software solution throughout the development process. These measures assess the quality of different software attributes, such as product size, cohesion, coupling, and complexity. Researchers and practitioners use software metrics to understand and improve software solutions and the processes used to develop them. Determining the relationship between software metrics aids in clarifying practical issues with regard to the relationship between the quality of internal and external software attributes. We conducted an empirical study on two open source systems (JEDIT and ANT) to study the defectiveness Evolution in Open Source Software Systems. The result reveals that a good designed software has lesser defects and have high cohesion. Moreover the study also revealed that defects are higher in initial versions and most corrected errors are from major classes in initial version. Removal of defects also reveals that a good software is consistently improved and feed backs are important part of open source systems. (C) 2016 The Authors.

The objective of this study was to develop a greenhouse environment measurement system using a low-cost microcontroller with open-source software. Greenhouse environment parameters measured were air temperature, relative humidity, and carbon dioxide (CO2) concentration. The ranges of the temperature, relative humidity, and CO2 concentration were -40 to 120 degrees C, 0 to 100\\%, and 0 to 10,000 ppm, respectively. A 128 x 64 graphic LCD display was used for real-time monitoring of the greenhouse environments. An Arduino Uno R3 consisted of a USB interface for communicating with a computer, 6 analog inputs, and 14 digital input/output pins. A temperature/relative humidity sensor was connected to digital pins 2 and 3. A CO2 sensor was connected to digital pins 12 and 13. The LCD was connected to digital pin 1 (TX). The sketches were programmed with the Arduino Software (IDE). A measurement system including the Arduino board, sensors, and accessories was developed (totaling \\$244). Data for the environmental parameters in a venlo-type greenhouse were obtained using this system without any problems.

+1501,InProceedings,EXPERIENCES USING FREE SOFTWARE SIMULATION TOOLS IN ENGINEERING HIGHER EDUCATION,"The advances experienced in the Information and Communication Technologies and the popularization of the devices with computing capacity have promoted the use of simulators, programs and programming languages as educational resources. However, the use of these tools for education purposes faces important barriers: the availability of the resources, the cost and the students' perception, among many others. These problems might be overcome by the use of free software simulators. In this paper, we present several experiences using free software tools in engineering Higher Education courses. The experiences shown cover several courses of different engineering Degrees: ``Electronics and Automation{''}, ``Electrical Engineering{''}, ``Computing{''} and ``Industrial Technologies{''}. These tools have been used in teaching activities for several years. As a result, the perceptions, gained experience and views of the teachers involved in the different courses are presented and discussed. Teachers specially valued the independence of the tools from commercial policies, as well as the suppression of expensive licenses. Additionally, they perceived that students understood better the simulations performed since all the parts of the tools could be freely accessed. They also remarked the possibility of changing the code at low level and fuse different free software projects together, what is not possible with the commercial tools. In addition, free software resources allowed students to start in a very common world currently, the collaborative communities, which may be of great importance in their future professional activities. However, teachers involved in these experiences also detected several drawbacks. In some cases, free software simulators are less robust than their commercial alternatives, which usually pay special attention at the design, being perceived by students as a signal of higher quality. In some simulators the documentation is incomplete, and there is a lack of easy-to-use examples which hinders the use of the tool by low-experienced users such as first-year students. The opportunities and threats faced by these tools are also discussed, concluding that when selecting an educational resource, the free software resources must be considered as perfectly valid options in the same conditions as the proprietary solutions.",NA

E-portfolios with mobile capabilities allow even more flexibility. However, the development or acquisition of ePortfolio software is often costly, and at the same time, commercially available systems may not sufficiently fit the institution's needs. The aim of this study was to design and evaluate an ePortfolio system with mobile capabilities using a commercially free and open source software solution. Methods: We created an online ePortfolio environment using the blogging software WordPress based on reported capability features of such software by a qualitative weight and sum method. Technical implementation and usability were evaluated by 25 medical students during their clinical training by quantitative and qualitative means using online questionnaires and focus groups. Results: The WordPress ePortfolio environment allowed students a broad spectrum of activities - often documented via mobile devices - like collection of multimedia evidences, posting reflections, messaging, web publishing, ePortfolio searches, collaborative learning, knowledge management in a content management system including a wiki and RSS feeds, and the use of aid tools for studying. The students' experience with WordPress revealed a few technical problems, and this report provides workarounds. The WordPress ePortfolio was rated positively by the students as a content management system (67 \\% of the students), for exchange with other students (74 \\%), as a note pad for reflections (53 \\%) and for its potential as an information source for assessment (48 \\%) and exchange with a mentor (68 \\%). On the negative side, 74 \\% of the students in this pilot study did not find it easy to get started with the system, and 63 \\% rated the ePortfolio as not being user-friendly. Qualitative analysis indicated a need for more introductory information and training. Conclusions: It is possible to build an advanced ePortfolio system with mobile capabilities with the free and open source software WordPress. This allows institutions without proprietary software to build a sophisticated ePortfolio system adapted to their needs with relatively few resources. The implementation of WordPress should be accompanied by introductory courses in the use of the software and its apps in order to facilitate its usability.",10.1186/s12909-016-0678-1

There are various methods for identification, such as fingerprinting, odontostomatology and genetic fingerprinting, which presuppose the existence of reference material of the missing person; however, if there is no evidence of a person's identity the only possibility is often the use of forensic facial soft tissue reconstruction. This method is based on the high recognition level of a human face on the basis of bony structures of the skull and its anatomical features. The aim of this study was the design and application of a novel process for a computer-aided 3D facial soft tissue reconstruction on the basis of digital photographs of a skull. The facial soft tissue reconstruction was carried out on a selected forensic case and based on open source software. A complete facial soft tissue reconstruction of the deceased person was created based on 76 photographs of the skull taken with a Nikon D7100 SLR digital camera. The results show that for actual comparison images similar reconstruction results can be achieved. In addition, a model library for facial features was created. The presented workflow of a computer-aided 3D facial soft tissue reconstruction based on open source software is a cost-effective and flexible alternative to conventional reconstruction methods.

A preliminary study was done to explore the state of OSS implementation among government agencies since the launch of the Malaysian Public Sector OSS Master Plan on July 16, 2004. Semi-structured face-to-face interviews using open-ended questions were conducted with IT managers and IT officers in the Northern Region of Peninsular Malaysia. The preliminary study aimed at investigating the usage of OSS and proprietary software, the level of OSS utilisation, the level of OSS knowledge and training of ICT and non-ICT staff, software development and acquisition model, internal OSS manpower capabilities and skills, the user's perception of the advantages of OSS, the user's perception of the risks of OSS, and the problems or barriers in OSS implementation. The results of interviews show that there are many problems or barriers in OSS implementation, e.g. lack of internal OSS expertise, lack of OSS policy, and lack of top management support.

+1512,Article,From Aristotle to Ringelmann: a large-scale analysis of team productivity and coordination in Open Source Software projects,"Complex software development projects rely on the contribution of teams of developers, who are required to collaborate and coordinate their efforts. The productivity of such development teams, i.e., how their size is related to the produced output, is an important consideration for project and schedule management as well as for cost estimation. The majority of studies in empirical software engineering suggest that - due to coordination overhead - teams of collaborating developers become less productive as they grow in size. This phenomenon is commonly paraphrased as Brooks' law of software project management, which states that ``adding manpower to a software project makes it later{''}. Outside software engineering, the non-additive scaling of productivity in teams is often referred to as the Ringelmann effect, which is studied extensively in social psychology and organizational theory. Conversely, a recent study suggested that in Open Source Software (OSS) projects, the productivity of developers increases as the team grows in size. Attributing it to collective synergetic effects, this surprising finding was linked to the Aristotelian quote that ``the whole is more than the sum of its parts{''}. Using a data set of 58 OSS projects with more than 580,000 commits contributed by more than 30,000 developers, in this article we provide a large-scale analysis of the relation between size and productivity of software development teams. Our findings confirm the negative relation between team size and productivity previously suggested by empirical software engineering research, thus providing quantitative evidence for the presence of a strong Ringelmann effect. Using fine-grained data on the association between developers and source code files, we investigate possible explanations for the observed relations between team size and productivity. In particular, we take a network perspective on developer-code associations in software development teams and show that the magnitude of the decrease in productivity is likely to be related to the growth dynamics of co-editing networks which can be interpreted as a first-order approximation of coordination requirements.",10.1007/s10664-015-9406-4
+1513,Article,Fuzzy analysis and prediction of commit activity in open source software projects,"Autoregressive integrated moving average (ARIMA) models are the most commonly used prediction models in the previous studies on software evolution prediction. This study explores a prediction method based on fuzzy time series for predicting the future commit activity in open source software (OSS) projects. The idea to choose fuzzy time series based prediction method is due to the stochastic nature of the OSS development process. Commit activity of OSS project indicates the activeness of its development community. An active development community is a strong contributor to the success of OSS project. Therefore commit activity prediction is an important indicator to the project managers, developers, and users regarding the evolutionary prospects of the project in future. The fuzzy time series-based prediction method is of order three and uses time variant difference parameter on the current state to forecast the next state data. The performance and suitability of computational method are examined in comparison with that of ARIMA model on a data set of seven OSS systems. It is found that the predicted results of the computational method outperform various ARIMA models. Towards the end, a commit prediction model is used for each project to analyse the trends in their commit activity.",10.1049/iet-sen.2015.0087
+1515,Article,Game theory and open source contribution: Rationale behind corporate participation in open source software development,"The rising participation of for-profit corporations in the development of open source software raises the question of why corporations are motivated toward this engagement. The increased participation is an observable phenomenon; many researchers and practitioners assume that the practice of community sharing does not improve the bottom line, but rather believe the practice is altruistic in nature. Our intuition is that participation offers tangible and intangible benefits to corporate participants. We show this by exploring a variety of models in game theory and use game theory as a methodological lens to explain the rationality of corporate participation in open source software development. Since game theory has evolved to include rational- and emotional-based reasons, we explore such lenses as cooperative games, metagames, coopetition, and Drama Theory. Our research question, Why do for-profit corporations participate in the development of open source software? was broad enough to adopt several useful perspectives to understand our data. One useful lens was game theory. In this article, we examine interview responses and field study data from corporate members of open source communities to determine how they justify devoting time and effort to community engagement. Our study makes a contribution to open source software literature by revealing that numerous rational and emotional reasons exist for corporate participation in open source software development.",10.1080/10919392.2016.1228360

Understanding the content types of forum messages and issue trackers can provide information about the extent to which requests are being addressed and issues are being resolved, the percentage of issues that are not being fixed, the cases where the user acknowledged that the issue was successfully resolved, etc. These indicators can provide potential adopters of the OSS with estimates about the level of available support.

We discuss our experiments to classify forum messages and issue tracker comments into content-related classes, i.e. to assign them to nodes of the hierarchy. The results are very encouraging.",NA

Various projects are in hand by different organizations to explore and implement the Mobile Adhoc Networking (MANET) feature on Android based devices due to their peculiar infrastructure-less requirements (such as disaster management, nomadic battle fields having no communication infrastructure, search and rescue operations etc). These projects carrying out research on MANETs have successfully implemented adhoc networking on few targeted devices, hence implementation of Mobile Adhoc Network (MANET) on every new Android based device is quite challenging in nature. We have researched on Commercial Off the Shelf (COTS) devices (such mobile phones and tablets) to implement adhoc networking using open source software (OSS) such as Serval Mesh, MANET Manager, WiFi Tether applications. We have also modified the TrevE-Mod WiFi Tether application to work successfully with MANET Manager and Linux/ Windows based Personal Computers (PCs) in an adhoc network. The results achieved by performance evaluation tools and testing of VoIP applications have proved it to be satisfactory. We have also satisfactorily implemented, configured and tested point to point Virtual Private Network (VPN) between MANET nodes using OSS (VPN Server, OpenVPN for Android, OpenVPN Connect). The application of standards based security algorithms (for authentication and encryption in VPNs) demonstrates that these technologies can be effectively used for secure collaboration in adhoc environments as well.",10.1109/CTS.2016.89

The significant amount of information that has been gathered in the publicly available open-source software repositories and mailing-list archives offers an opportunity to analyze projects structures and participant involvement. In this article, using on commits data from 263 Apache projects repositories (nearly all), we show that although OSS development is often described as collaborative, but it in fact predominantly relies on radically solitary input and individual, non-collaborative contributions.

To capture user innovation and to maintain quality of software and productivity of teams, these projects need to attract and retain contributors. Aim: We want to understand and quantify how inflow and retention are shaped by policies and actions of companies in three application server projects. Method: We identified three hybrid projects implementing the same JavaEE specification and used published literature, online materials, and interviews to quantify actions and policies companies used to get involved. We collected project repository data, analyzed affiliation history of project participants, and used generalized linear models and survival analysis to measure contributor inflow and retention. Results: We identified coherent groups of policies and actions undertaken by sponsoring companies as three models of community involvement and quantified tradeoffs between the inflow and retention each model provides. We found that full control mechanisms and high intensity of commercial involvement were associated with a decrease of external inflow and with improved retention. However, a shared control mechanism was associated with increased external inflow contemporaneously with the increase of commercial involvement. Implications: Inspired by a natural experiment, our methods enabled us to quantify aspects of the balance between community and private interests in open-source software projects and provide clear implications for the structure of future open-source communities.",10.1145/2876443

Loose couplings lead to dissemination or retrieval of information, spread of viruses, new product adoption, more and their prediction is significant for knowledge management, organizational innovation, epidemics of contagious diseases, and viral product design. Therefore in this paper, we investigate how to predict inter-cluster tie strength, and propose that inter-cluster tie strength can be predicted from determination of intra-cluster density. In the model design section, we provide the hypothesis and discuss logical and analytical reasoning; in the empirical section, we alternatively examine the relationship between intra-group density and inter-group tie strength via examining open-source-software (OSS) project collaboration data collected from SourceForge repository.",10.1007/978-3-319-40162-1\\_18
+1530,Article,Investigating and Projecting Population Structures in Open Source Software Projects: A Case Study of Projects in GitHub,"GitHub is a developers' social networking service that hosts a great number of open source software (OSS) projects. Although some of the hosted projects are growing and have many developers, most projects are organized by a few developers and face difficulties in terms of sustainability. OSS projects depend mainly on volunteer developers, and attracting and retaining these volunteers are major concerns of the project stakeholders. To investigate the population structures of OSS development communities in detail and conduct software analytics to obtain actionable information, we apply a demographic approach. Demography is the scientific study of population and seeks to identify the levels and trends in the size and components of a population. This paper presents a case study, investigating the characteristics of the population structures of OSS projects on GitHub, and shows population projections generated with the well-known cohort component method. We found that there are four types of population structures in OSS development communities in terms of experiences and contributions. In addition, we projected the future population accurately using a cohort component population projection method. This method predicts a population of the next period using a survival rate calculated from past population. To the best of our knowledge, this is the first study that applied demography to the field of OSS research. Our approach addressing OSS-related problems based on demography will bring new insights, since studying population is novel in OSS research. Understanding current and future structures of OSS projects can help practitioners to monitor a project, gain awareness of what is happening, manage risks, and evaluate past decisions.",10.1587/transinf.2015EDP7363

On Automated Redundant OSS Feature Requests Identification,"Open source projects rely on issue tracking systems such as JIRA or online forums to keep track of users' feedback, expectations and requested features. However, since users are not fully aware of existing features, when submitting new feature requests, redundant requests often appear in the new feature list. It is a waste of time and effort for project contributors to manually identify and reject them, especially in complex systems with many features. Our research is aiming to find a suitable solution to identify redundant feature requests in OSS projects. We have conducted a survey on a well-known Open Source community, Hibernate and gathered all of its feature requests up-to-date. Through studying and categorizing the characteristics of these feature requests, we have found that about 37\\% of the feature requests were rejected and the most common rejection reason was redundancy. Also we have found that it is very expensive to identify and resolve these redundant feature requests. In this paper, we have proposed our solution to automatically identify redundant feature requests through a Feature Tree Model along with a future research agenda.",10.1109/RE.2016.65

+1535,InProceedings,Knowledge Sharing Profiles in Free Software Communities,"Knowledge is an obtainable, renewable, dynamic, context-dependent resource that is capable of providing competitive advantage in organizations. Knowledge can be shared, and the knowledge sharing cycle has two processes: knowledge donation, when a person voluntarily offers his intellectual capital to others, and knowledge collection, when a person consults other people's intellectual capital. Knowledge sharing is important for, among other reasons, improving organizational learning, innovative capacity, organizational success and productivity. Knowledge can be shared among individuals, groups and organizations. One kind of group organized to share knowledge is the community of practice, where people have mutual relationships involving a regular flow of knowledge between them, which facilitates the generation of new knowledge. A free software community is a type of community of practice arranged around a specific free software. The knowledge shared in free software communities is complex and the knowledge sharing processes have scarcely been studied in this environment. This investigation aims to identify the profiles of knowledge sharing processes in free software communities i.e., whether members of free software communities collect more, donate more or collect and donate equally. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters, corresponding to the sharing profiles of the respondents, were identified: Sporadic Sharer (low donation and low collection); Collector (low donation and high collection); Donator (high donation and low collection); and Constant Sharer (high donation and high collection). The k-means algorithm showed four well-defined clusters. Interestingly, with the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators (that emphasize donation) and Collectors (that emphasize collection). These results confirm the view of free software communities as communities of practice that are organized to share knowledge, and highlight the importance of knowledge sharing and collaboration in the free software development cycle. Furthermore, the results show that the Constant Sharer (that both collects and donates intensely) is the profile that donates and collects more, even more than Donators and Collectors, indicating that this profile is key to the correct functioning of the community.",NA

+1539,InProceedings,MAESTROS: Multi-Agent Simulation of Rework in Open Source Software,"Rework Management in software development is a challenging and complex issue. Defined as the effort spent to re-do some work, rework implies big costs given the fact that the time spent on rework does not count to the improvement of the project. Predicting and controlling rework causes is a valuable asset for companies, which maintain closed policies on choosing team members and assigning activities to developers. However, a trending growth in development consists in Open Source Software (OSS) projects. This is a totally new and diverse environment, in the sense that not only the projects but also their resources, e.g., developers change dynamically. There is no guarantee that developers will follow the same methodologies and quality policies as in a traditional and closed project. In such world, identifying rework causes is a necessary step to reduce project costs and to help project managers to better define their strategies. We observed that in real OSS projects there are no fixed team, but instead, developers assume some kind of auction in which the activities are assigned to the most interested and less-cost developer. This lead us to think that a more complex auctioning mechanism should not only model the task allocation problem, but also consider some other factors related to rework causes. By doing this, we could optimise the task allocation, improving the development of the project and reducing rework. In this paper we presented MAESTROS, a Multi-Agent System that implements an auction mechanism for simulating task allocation in OSS. Experiments were conducted to measure costs and rework with different project characteristics. We analysed the impact of introducing a Q-learning reinforcement algorithm on reducing costs and rework. Our findings correspond to a reduction of 31\\% in costs and 11\\% in rework when compared with the simple approach. Improvements to MAESTROS include real projects data analysis and a real-time mechanism to support Project Management decisions.",10.1007/978-3-319-25017-5\\_6

However, frequent personnel turnover and lack of organizational management makes it difficult to capture the actual development effort. Various OSS maintenance effort estimation approaches have been developed to provide a way to understand and estimate development effort. The goal of this study is to identify the current state of art of the existing maintenance effort estimation approaches for OSS. We performed a systematic literature review on the relevant studies published in the period between 2000-2015 by both automatic and manual searches from different sources. We derived a set of keywords from the research questions and established selection criteria to carefully choose the papers to evaluate. 29 out of 3,312 papers were selected based on a well designed selection process. Our results show that the commonly used OSS maintenance effort estimation methods are actual effort estimation and maintenance activity time prediction; the most commonly used metrics and factors for actual effort estimation are source code measurements and people related metrics; the most commonly mentioned activity for maintenance activity time prediction is bug fixing. Accuracy measures and cross validation is used for validating the estimation models. Based on the above findings, we identified the issues in evaluation methods for actual maintenance effort estimations and the needs for quantitative OSS maintenance effort inference from size-related metrics.

Our narratives indicate that for both cases there was strong goodwill towards open source yet the trajectories of implementation differed widely. Drawing upon ideas of change(ing), mutability and materiality we unpack the process of adoption. The study shows that open source software has certain facets; code, community, coordination mechanisms, license and documentation. Each facet is not stable; indeed, it is changing and mutable. This creates possibilities, potential but also recalcitrance, and barriers. The interesting point of departure of our study is how open source software a much touted transparent and open phenomenon is by its nuanced and layered mutability able to make the process and practices surrounding it less visible. It concludes with clear policy recommendations developing from this research that could help to make open source adoption more sustainable in the public sector. (c) 2015 Elsevier Inc.

Free open-source software tools for documenting, analyzing, visualizing, and sharing using electronic notebooks","Neurophysiology requires an extensive workflow of information analysis routines, which often includes incompatible proprietary software, introducing limitations based on financial costs, transfer of data between platforms, and the ability to share. An ecosystem of free open-source software exists to fill these gaps, including thousands of analysis and plotting packages written in Python and R, which can be implemented in a sharable and reproducible format, such as the Jupyter electronic notebook. This tool chain can largely replace current routines by importing data, producing analyses, and generating publication-quality graphics. An electronic notebook like Jupyter allows these analyses, along with documentation of procedures, to display locally or remotely in an internet browser, which can be saved as an HTML, PDF, or other file format for sharing with team members and the scientific community. The present report illustrates these methods using data from electrophysiological recordings of the musk shrew vagus-a model system to investigate gut-brain communication, for example, in cancer chemotherapy-induced emesis. We show methods for spike sorting (including statistical validation), spike train analysis, and analysis of compound action potentials in notebooks. Raw data and code are available from notebooks in data supplements or from an executable online version, which replicates all analyses without installing software-an implementation of reproducible research.

Here we present a new software tool, OPAL (Offset Portfolio Analyzer and Locator), which maps and quantifies the impacts of development on habitat and ecosystem services, and facilitates the selection of mitigation activities to offset losses. We demonstrate its application with an oil and gas extraction facility in Colombia. OPAL is the first tool to provide direct consideration of the distribution of ecosystem service benefits among people in a mitigation context. Previous biodiversity-focused efforts led to redistribution or loss of ecosystem services with environmental justice implications. Joint consideration of biodiversity and ecosystem services enables targeting of offsets to benefit both nature and society. OPAL reduces the time and technical expertise required for these analyses and has the flexibility to be used across a range of geographic and policy contexts. (C) 2016 Elsevier Ltd.

The study is conducted on 19 open source systems comprising over 9.8 Million lines of code (MLOC). Each system is analyzed and the number of function side effects is determined. The results show that global variables modification and parameters by reference are the most prevalent side effect types. Thus, conducting accurate program analysis or many adaptive changes processes (e.g., automatic parallelization to improve their parallelizability to better utilize multi-core architectures) becomes very costly or impractical to conduct. Analysis of the historical data over a 7-year period for 10 systems shows that there is a relatively large percentage of affected functions over the lifetime of the systems although trend is flat in general, thus posing further problems for inter-procedural analysis.",10.1007/978-3-319-33903-0\\_9

However, traditional resume only shows experiences claimed by developers, and very few evidence or information regarding their actual development activities can be obtained. In this paper, we propose an approach to extract developers' practical activities from their participated open source software (OSS) projects, and generate the biographies that reflect their OSS contributions. We applied the approach on the largest code hosting service, GitHub. By investigating the resumes generated from the extracted dataset, recruiters of software projects can be given a clearer view on whether the developers' experiences fulfill the qualifications. Moreover, based on the approach, we present a web-based visualization tool, named as Open Source Resume (OSR). We believe our tool is useful to help recruiters from software development organizations to search for suitable developers, and then construct development teams in software projects based on their OSS contributions.",10.1109/IWESEP.2016.17

Numeouus SRGMs have been proposed to estimate the reliability of the software of OSSs; however, no one has proven to perform very well considering diverse project characteristics. In the models for OSSs, the error deletion experience for the reused and the newly developed components based on component-specific testing-effort is demonstrated. It is considered that there are several different types of faults for newly developed component and single type of faults for reused components for obtaining the unambiguous expressions for the mean number of individual types of errors. For OSSs system components testing-efforts have to be modeled separately for each and every component in the system. The total effort of the system is then calculated from the summation of component-specific testing-effort functions. We have employed MATLAB as implementation framework for performing all the estimations. Our approach partitions the testing effort with growth curves of varying nature among different components of the same OSS. To validate our analytical results, numerical illustrations have also been provided.",10.1145/2905055.2905283

+1566,Article,PM2.5 and ash residue from combustion of moxa floss,"Background Moxibustion, a Traditional Chinese Medicine technique, involves burning moxa floss to apply heat to certain points or areas of the body surface to treat disease. Moxibustion releases a considerable amount of smoke into the environment. There remains controversy over the safety of moxa smoke and its potential effects on human health. Methods We measured the PM2.5 (particulate matter with aerodynamic diameter <2.5m) mass concentration in moxa smoke and the oxidative capacity of PM2.5 and moxa ash (using a plasmid scission assay in whole and water-soluble fractions) in the by-products of moxibustion produced from burning moxa floss of different ratios (3:1 or 15:1) and duration of storage (3 or 10years) in three simulated moxibustion clinics. Results PM2.5 mass concentration was 224.28, 226.39 and 210.56g/m(3) for samples A (3years and 3:1 ratio), B (3years and 15:1 ratio), and C (10years and 3:1 ratio), respectively. Average D-500 oxidative damage of PM2.5 was 29.42\\%, 29.16\\% and 27.01\\% and that of moxa ash was 22.78\\%, 20.60\\% and 21.42\\% for samples A, B and C, respectively. PM2.5 demonstrated a significantly greater oxidative capacity than moxa ash (p<0.05). Conclusions The oxidative DNA damage induced by individual PM2.5 following moxibustion was lower than that reported in other environments. However, PM2.5 mass concentration after moxibustion is still relatively high. We would recommend ensuring adequate ventilation during moxibustion to reduce any possible risks. Further studies are needed to better define the potential impact of particles in moxibustion by-products on human health.",10.1136/acupmed-2015-010914

In the case of orthopaedic and dental implants it was found that geometry and surface topography are crucial for short and long-term success of the implant, due to its effects in osseointegration. Properties of implant surfaces have been studied in the last decade in a concentrated effort to improve osseointegration process and implant success. Several researchers have proved that roughness of implant surface is related to healing time and integration between the implants and the bone, but the parameters on the surface creation are not fully controllable with current processes. In this work, computational algorithms are proposed for implant surface design in order to control the parameters required for this application. As a result it is presented an open-source software tool, called POMES - Porous and Modifications for Engineering Surfaces - , to design porous/roughness on top of surfaces in any geometry. Additionally, an example model was fabricated using POMES and additive manufacturing. (C) 2015 The Authors. Published by Elsevier B.V.",10.1016/j.procir.2015.07.085

Methods: CBCT scans were retrieved from endodontic records of two patients. Threedimensional virtual models, voxel counting, volumetric measurement (mm(3)) and mean intensity of the periapical lesion were performed with ITK-SNAP v. 3.0 software. Threedimensional models of the lesions were aligned and overlapped through the MeshLab software, which performed an automatic recording of the anatomical structures, based on the best fit. Qualitative and quantitative analyses of the changes in lesions size after treatment were performed with the 3DMeshMetric software. Results: The ITK-SNAP v. 3.0 showed the smaller value corresponding to the voxel count and the volume of the lesion segmented in yellow, indicating reduction in volume of the lesion after the treatment. A higher value of the mean intensity of the segmented image in yellow was also observed, which suggested new bone formation.

Due to this, many software fails to get repair within real time constraint. Ascribe to technology advancements and changing requirements, software must be well developed and maintained to get adapted. Hence, it is necessary to predict software maintainability in the early phases of the lifecycle so that optimization of resources can be possible and cost can be reduced. Software Maintainability is the quality attribute of software product that explains the ease with which modifications can be performed. The main focus in this study is to propose the use of Gene Expression Programming (GEP) for the software maintainability prediction and measure its performance with various machine leaning techniques such as Decision Tree Forest, Support Vector Machine, Linear regression, Multilayer Perceptron and Radial basis function neural network. The empirical study is conducted with the help of four open source datasets. Eleven bad smells are identified and is considered as maintenance effort. Results of this study show that GEP algorithm performs better than machine learning classifiers; hence it can be used as sound alternative in the prediction of software maintainability.

+1572,Article,Problem-formulation and problem-solving in self-organized communities: How modes of communication shape project behaviors in the free open-source software community,"Research summary: Building on the problem-solving perspective, we study behaviors related to projects and the communication-based antecedents of such behaviors in the free open-source software (FOSS) community. We examine two kinds of problem/project-behaviors: Individuals can set up projects around the formulation of new problems or join existing projects and define and/or work on subproblems within an existing problem. The choice between these two behaviors is influenced by the mode of communication. A communication mode with little a priori structure is the best mode for communicating about new problems (i.e., formulating a problem); empirically, it is associated with project launching behaviors. In contrast, more structured communication fits subproblems better and is related to project joining behaviors. Our hypotheses derive support from data from the FOSS community.Managerial summary: We study how the way in which individuals communicate influence the project-behaviors they engage in. We find that relatively unstructured communication is associated with the setting up new projects, while communication that is structured around an artifact is associated with joining projects. Our findings hold implications for understanding how management may influence project behaviors and problem-solving: Firms that need to concentrate on more incremental problem-solving efforts (e.g., because a sufficient number of attractive problems have already been defined) should create environments in which interaction is undertaken mainly via artifacts. On the other hand, if firms seek to generate new problems (e.g., new strategic opportunities), they should create environments in which open-ended, verbal conversation is relatively more important than artifact-based communication.

While a large body of studies focuses on the importance of developers' reputations in their participation motivations, there is still lack of understanding for two issues. First, which factors can lead to a high developer's reputation? Second, how does the overall reputation of the developers' in a project impact project success? In this study, we develop a theoretical model and conduct an empirical analysis in a large online open source community. The results show that a developer's reputation level is determined by his or her 1) coding quality, 2) the deviation of the commitment behavior, 3) community experience, and 4) collaboration experience. In addition, we find that the group with an overall higher level of reputation would achieve a better performance, while the individual reputation level deviation within the group would impair its technical success.

Long-term follow-up of implants placed in BCP after sinus augmentation is still missing. Purpose: The primary aim of the study was to compare survival rates and marginal bone loss of Straumann SLActive implants placed in either BCP (test) or Bio-Oss (R) (DBB) (control) after sinus floor augmentation. The secondary aim was to calculate graft sinus height at different time points. Materials and Methods: Bilateral sinus floor augmentation was performed in a split mouth model. Eleven patients (mean age 67 years) received 100\\% BCP on one side and 100\\% DBB on the contralateral side. After 8 months of graft healing, 62 Straumann SLActive implants were placed. After 5 years of functional loading (6 years after augmentation) of implants, marginal bone levels and grafted sinus height were measured, and implant survival and success rates were calculated. Results: After 5 years of loading, all prosthetic constructions were in function although two implants were lost in each grafting material. The overall implant survival rate was 93.5\\% (91.7\\% for BCP, 91.3\\% for DBB, and 100\\% for residual bone). The success rates were 83.3\\% and 91.3\\% for BCP and DBB, respectively.

This analytic distinction presents some limitations in explaining how coordination is reached in organizations characterized by distributed teams, scarce face to face meetings and fuzzy and changing lines of authority, as in free/libre open source software (FLOSS) development. Analyzing empirical illustrations from two FLOSS projects, we highlight the existence of a peculiar model, stigmergic coordination, which includes aspects of both implicit and explicit mechanisms. The work product itself (implicit) and the characteristics under which it is shared (explicit) play an under-appreciated role in helping software developers manage dependencies as they arise. We develop this argument beyond the existing literature by working with an existing coordination framework, considering the role that the codebase itself might play at each step. We also discuss the features and the practices to support stigmergic coordination in distributed teams, as well as recommendations for future research. (C) 2016 The Authors.

Generalized refractory chronic periodontitis is a periodontal condition that is resistant to conventional therapy. Management of this condition often is frustrating to both the patient and the clinician. Case Descriptions. The authors present 4 cases of generalized refractory chronic periodontitis characterized by an inflammatory gingival response and progressive bone loss that did not respond to extensive periodontal treatments and regular periodontal care. Histologic examination of affected gingival tissue revealed an abundance of plasma cells, a feature seen in certain oral contact hypersensitivity reactions. The authors suspected that waxed or coated dental floss was the offending contactant, and its removal from the patients' oral hygiene regimens resulted in a dramatic improvement of the periodontal characteristics. Conclusions and Practical Implications. In cases of periodontal disease as described in this report, dental practitioners should consider the possibility of a contact hypersensitivity reaction to waxed or coated dental floss, whereby the floss exacerbates the condition instead of assisting in its resolution.",10.1016/j.adaj.2016.06.009

+1596,InProceedings,TEACHING RENEWABLE ENERGIES USING FREE SOFTWARE: A CASE STUDY WITH R APPLIED TO OCEAN ENERGY,"The University of the Basque Country (http://www. ehu. es) is the most important University in the Autonomous Region of the Basque Country, Spain. There is one degree in Renewable Energy Engineering given at the Gipuzkoa Faculty of Engineering (Eibar). In the last year of their studies, students, can select one subject on Ocean Energy. In this subject, state-of-the-art operation and management techniques are taught to the students. Apart from the transmission of this knowlegde, the focus is practical and is based on hands-on computer real-life exercises, which involves not only intensive programming using a high-level software, but also the spatial representation of results. This is important because currently two major research and development lines can be identified as far as ocean energy is concerned. The first one is the analysis of prototypes that in the future will extensively extract electricity from wave farms. The second one is related to the resource itself, which implies the analysis and characterization of some ocean variables related to the extraction of energy. In many cases, the raw information on some oceanic variables of interest is available from institutions like the ECMWF http://www.ecmwf.int However a very extensive phase of data preprocessing is needed to extract useful information on wave energy potential. This will be an important task for future engineers involved in the spatial planning of oceanic energy facilities and in real-time forecasting and control of electricity obtained at wave farms. For this reason, students need to effectively learn to do all these tasks. R (https://www.cran.r-project.org/) is a freely available software that provides an optimum answer to these combined needs and teaching challenges due to its modular structure. R has a core module and nearly 8000 packages specifically developed for different purposes are also available. Packages like ``RNetCDF{''}, ``sp{''} ``rgeos{''}, ``rgdal{''}, ``maps{''}, ``maptools{''} and ``mapdata{''} have been developed to make R work with full functionalities just like any high-level programming software. Incorporating R into the teaching activities of the subject ``Ocean Energy{''} has represented an important step forward in the education of future engineers while providing them with real-life tools for their future jobs in wave farms.",NA

The advent of publicly available DEM data has provided a cheaper, low-cost alternative to traditional field data collection and survey. Handling, processing, and visualization of such data on an open-source software will provide researchers and specialists a better and faster way of generating digital terrain maps and creating input data for other analyses.

Open source systems have moved from just educational projects to mainstream research area. Successful and active open source projects are numbering more than thousands that needs to be tested and their quality level needs to be determined. There are several ways to measure the quality of software systems. Mainly, measuring the ability of test cases to detect and find defects is used. This research focuses on finding a good technique to evaluate the effectiveness of test cases for finding defects in open source systems. Experiments are conducted on six OSS (open source software).

+1599,InProceedings,The Effects and Antecedents of Conflict in Free and Open Source Software Development,"Conflict is an important group process, and more so in self-organizing teams with fluid boundaries and high possibility for turnover. We empirically investigate different types of conflict in Free and Open Source Software development teams, their antecedents and impact on developers' sustained participation. Following a survey of 222 FOSS developers, we find conflict to have an overall negative effect on developer retention. Furthermore, different types of conflict have varying impact on outcomes. In particular, only normative conflict levels negatively impact intention to remain in a FOSS project. Both normative and process conflict negatively affect perceptions of team performance, while the co-occurrence of task and process conflict exacerbate negative effects on outcomes. Though we find structural factors like task interdependence and geographical distribution increase overall conflict levels in FOSS teams, participatory decision-making and a transformational leadership style have an ameliorating effect. Implications for theory and practice are discussed.",10.1145/2818048.2820018

This study is expected to provide an understanding on how communication patterns established in different roles and different levels. The authors not only measured OSS success from both developers and users' perspectives, but also extended the existing research by including the potential relationships among these success measures in the estimation model. Following the panel data econometric analysis methodology, they evaluated their research hypotheses using the Three-Stage Least Squares model, accounting for both time-period and project fixed effects. The authors' results indicated that according to the objectives of projects, a proper and planned control for the communication among team members is crucial for the success of OSS projects.",10.4018/JGIM.2016100102
+1605,Article,The Influence of Risk Factors in Decision-Making Process for Open Source Software Adoption,"``Nobody ever got fired for buying IBM,{''} was a widely used cliche in the 1970s in the corporate IT (information technology) world. Since then, the traditional process of purchasing software has dramatically changed, challenged by the advent of open source software (OSS). Since its inception in the 1980s, OSS has matured, grown, and become one of the important driving forces of the enterprise ecosystem. However, it has also brought important IT security risks that are impacting the OSS IT adoption decision-making process. The recent Heartbleed bug demonstrated the grandeur of the issue. While much of the noise relates to the amplification of perceived risks by the popular mass media coverage, the effect is that many enterprises, mainly for risk reasons, have still chosen not to adopt OSS. We investigated ``how do information security related characteristics of OSS affect the risk perception and adoption decision of OSS{''} by conducting an online survey of 188 IT decision-makers. The proposed Open Source Risk Adoption Model offers novel insights on the importance of the perceived risk antecedents. Our research brings new theoretical contributions, such as understanding the perceived IT security risk (PISR) relationship with adoption intention (AI) in the OSS context, for researchers and important insights for IT information professionals. We have found that IT security risk has a significant role in OSS adoption intention. Our results offer possible future research directions and extend existing theoretical understanding of OSS adoption.",10.1142/S0219622015500364
+1606,InProceedings,The Role of Open Source Software in Program Analysis for Reverse Engineering,"Program analysis is the process of statically or dynamically retrieving the structure and behavior of software systems. Static analysis solely relies on the availability of source code of computer programs, while dynamic analysis captures program information using execution traces during program runtime. The entire process is called software reverse engineering, where the extracted information could eventually be visualized to facilitate program comprehension for the sake of learning, maintenance, etc. Open source software, in this context, plays a vital role in developing, enriching, and validating program analysis techniques. In this paper, we show and discuss how open source software projects significantly contribute to the development, evolution, and validation of program analysis techniques as well as enriching reverse-engineered diagrams with useful and meaningful information, even for those techniques that rely on dynamic analysis.",NA
+1607,Article,The Use of Security Tactics in Open Source Software Projects,"Despite the best intentions of software architects, it is often the case that individual developers do not faithfully implement the original security design decisions. Such a scenario sometimes leads to a situation in which while an architect claims the use of a secure architecture in the form of some tactic, the corresponding source code does not support the claim. To bridge this gap, the first critical step is to verify whether the source code reflects at least some of the structural or behavioral features required for a tactic. In this study, we examine the extent of this discrepancy between an architect's vision of what security tactics need to be adopted in the software and the actual implementation. We accomplish this research goal by 1) exploring an architect's intention to use security tactics, 2) checking whether the tactic is manifested in the design, and finally 3) recovering the evidence of efforts to implement the design in the source code. To avoid limitations to accessing documentation and source code, we use open source projects to conduct our research.",10.1109/TR.2015.2500367
+1608,Article,The fundamentals behind solving for unknown molecular structures using computer-assisted structure elucidation: a free software package at the undergraduate and graduate levels,"The successful elucidation of an unknown compound's molecular structure often requires an analyst with profound knowledge and experience of advanced spectroscopic techniques, such as Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry. The implementation of Computer-Assisted Structure Elucidation (CASE) software in solving for unknown structures, such as isolated natural products and/or reaction impurities, can serve both as elucidation and teaching tools. As such, the introduction of CASE software with 112 exercises to train students in conjunction with the traditional pen and paper approach will strengthen their overall understanding of solving unknowns and explore of various structural end points to determine the validity of the results quickly.

+1610,Article,The hacker ethic vs netarchical capitalism: free software and peer production within collaborative economic practices in Andalusia,"Over the last few years the notion of the Collaborative Economy has become increasingly popular despite the lack of consensus around its meaning. This term includes a wide variety of experiences from time banks and urban gardens to startups or digital platforms. The recent expansion of all tthese initiatives can be linked to a combination of factors such as the technological development, economic recession and other overlapping crises (environmental, care, political.) and changing social values. During 2014-2015, two almost parallel studies were undertaken following a similar methodology. The first one was aimed at defining and identifying Collaborative Economy practices linked to Andalusia's public universities. The second study searched for entrepreneurship sharing initiatives in the region. The results led to the following question about the nature of the Collaborative Economy: Is it possible to define these practices as postcapitalist initiatives and do they promote a fairer and more equalitarian society or do they respond to capital forces and simply aim to continue extracting and privatizing value which is socially generated? This article analyses a specific set of initiatives identified in Andalusia, those based on open source software and digital production. Its conclusions are that, these initiatives are, up to a point, embedded with the hacker ethic and the logics of open knowledge. Therefore, they could be situated within the promotion of a global commons which is opposed to the hegemonic logics of netarchical capitalism.",10.5209/rev\\_TK.2016.v13.n1.51936

The clip with line traction method was reported to improve ESD. However, there was no comparison with conventional ESD especially for trainees. We report here on the feasibility and efficacy of traction using dental floss with endoscopic clip to facilitate ESD versus conventional method for ESD trainees. Twenty simulated gastric lesions, paired with location and size, were created in porcine stomachs using a standard template. After a circular incision was made, submucosal dissection (control, n = 10) was performed with standard ESD, while the study (clip, n = 10) was performed with traction using dental floss and endoclip. Primary outcome was speed of submucosal dissection. Secondary outcome included frequency of submucosal injection and adverse event. Compared with controls, median procedure time was significantly shorter in the clip group (5.6 +/- A 1.1 vs. 13.6 +/- A 2.5 min, P = 0.003), with a significantly faster submucosal dissection time (1.8 +/- A 0.3 vs. 0.6 +/- A 0.1 cm(2)/min, P = 0.001) and less frequent submucosal injection (5.7 +/- A 0.6 vs. 8.5 +/- A 1.0 times, P = 0.024). There were no perforations in either group, but less adverse events (bleeding and injury to muscularis propria) in the clip group (1 vs. 7, P = 0.068, alpha = 0.1). Traction provided by dental floss and endoclip improves visualization of the submucosal layer during ESD. It allows a faster and safer gastric ESD especially among trainees in the early learning phase.",10.1007/s00464-015-4598-7

However, newcomers to OSS face several challenges when joining a project. Particularly, they do not know where to start, or choose tasks that they can be successful at. Our vision, BugExchange, is a system that curates tasks from OSS projects to help train newcomers. While evaluating and executing these tasks, newcomers can gain an understanding about the project, its technology, and concepts. There are many challenges in designing such a system. For example, identifying the information needs of newcomers, creating task recommendations that match newcomers' skills and career goals, and providing mentoring and networking support.

This study explores a fuzzy data mining algorithm for time series data to generate the association rules for evaluating the existing trend and regularity in the evolution of open source software project. The idea to choose fuzzy data mining algorithm for time series data is due to the stochastic nature of the open source software development process. Commit activity of an open source project indicates the activeness of its development community. An active development community is a strong contributor to the success of an open source project. Therefore commit activity analysis along with the trend and regularity analysis for commit activity of open source software project acts as an important indicator to the project managers and analyst regarding the evolutionary prospects of the project in the future.",10.1155/2016/1479692

+1620,Article,VeriSiMPL 2: An open-source software for the verification of max-plus-linear systems,"This work presents a technique to generate finite abstractions of autonomous Max-Plus-Linear (MPL) systems, a class of discrete-event systems employed to characterize the dynamics of the timing related to the synchronization of successive events. Abstractions of MPL systems are derived as finite-state transition systems. A transition system is obtained first by partitioning the state space of the MPL system into finitely many regions and then by associating a unique state of the transition system to each partitioning region. Relations among the states of the transition system are then set up based on the underlying dynamical transitions between the corresponding partitioning regions of the MPL state space. In order to establish formal equivalences, the obtained finite abstractions are proven either to simulate or to bisimulate the original MPL system. The approach enables the study of general properties of the original MPL system formalized as logical specifications, by verifying them over the finite abstraction via model checking. The article presents a new, extended and improved implementation of a software tool (available online) for the discussed formal abstraction of MPL systems, and is tested on a numerical benchmark against a previous version.",10.1007/s10626-015-0218-x
+1621,Article,Watching Kinetic Studies as Chemical Maps Using Open-Source Software,"A nonproprietary software package, ``PyMca{''}, primarily developed for X-ray fluorescence analysis offers an easy-to-use interface for calculating maps, by integrating intensity (of X-ray fluorescence, as well as any spectral data) over Regions Of Interest (ROT), by performing per pixel operations or by applying multivariate analysis. Here we show that, while initially developed to analyze hyperspectral two-dimensional (spatial) maps, this tool can be beneficial as well to anyone interested in measuring spectral variations over one or two dimensions, these dimensions being time, temperature, and so on. Different possibilities offered by the software (preprocessing, simultaneous analysis of replicas, of different conditions, ROT calculation, multivariate analysis, determination of reaction rate constant and of Arrhenius plot) are illustrated with two examples. The first example is the Fourier transform infrared spectroscopy (FTIR) follow-up of the saponification of oil by lead compounds. The disappearance of reagent (oil) and formation of products (lead carboxylates and glycerol) can be easily followed and quantified. The second example is a combined extended X-ray absorption fine structure (EXAFS), diffuse reflectance infrared Fourier transform spectroscopy (DRIFT), and mass spectroscopy (MS) analysis of RhAl2O3 catalyst under NO reduction by CO in the presence of O-2. It is possible to appreciate, in a single shot, Rh particles' structure and surface changes and gas release and adsorption in the reaction conditions.",10.1021/acs.analchem.5b04819

But the situation in FLOSS (free, libre, open source software) development is really extreme in this respect: past publications and studies show a female participation of around 2\\% to 5\\% and have shed some light into this problem. In this paper, we give an update the state of knowledge to the current situation of gender in FLOSS, by analyzing the results of surveying more than 2,000 contributors to FLOSS projects in 2013, of which more than 200 were women. Our findings confirm that women enter the FLOSS community later than men, do primarily other tasks than coding, participate less if they have children, and have slightly different reasons to enter (and to stay in) the development communities they join. However, we also find evidence that women are joining FLOSS projects in higher numbers in recent years, and that the share of women devoting few hours per week to FLOSS and full-time dedication is higher than for men. All in all, comparing our results with the ones from the 2000s, the context of participation of women in FLOSS has not changed much.",10.1007/978-3-319-39225-7\\_13

This pushed a paradigm shift for moving to sustainable development through processes of stakeholder engagement to improve the efficiency and transparency of decision processes. In this context, this research project developed a free and open-source GIS software, called FloodRisk, to operatively support stakeholders in their compliance with risk map delineation and the management of current and future flood risk based on their needs for multi-purpose applications. In this paper, a high-resolution impact assessment framework based on 2D inundation modelling with different return periods was used, as input, within the FloodRisk model to reconstruct the socio-economic damages based on a case study showing how structural and non-structural measures can significantly decrease the cost of floods for households.

Meta-analysis and meta-regression are statistical methods for synthesizing and modelling the results of different studies, and are critical research synthesis tools in ecology and evolutionary biology (E\\&E). However, many E\\&E researchers carry out meta-analyses using software that is limited in its statistical functionality and is not easily updatable. It is likely that these software limitations have slowed the uptake of new methods in E\\&E and limited the scope and quality of inferences from research syntheses. 2. We developed OpenMEE: Open Meta-analyst for Ecology and Evolution to address the need for advanced, easy-to-use software for meta-analysis and meta-regression. OpenMEE has a cross-platform, easy-to-use graphical user interface (GUI) that gives E\\&E researchers access to the diverse and advanced statistical functionalities offered in R, without requiring knowledge of R programming. 3. OpenMEE offers a suite of advanced meta-analysis and meta-regression methods for synthesizing continuous and categorical data, including meta-regression with multiple covariates and their interactions, phylogenetic analyses, and simple missing data imputation. OpenMEE also supports data importing and exporting, exploratory data analysis, graphing of data, and summary table generation. 4. As intuitive, open-source, free software for advanced methods in meta-analysis, OpenMEE meets the current and pressing needs of the E\\&E community for teaching meta-analysis and conducting high-quality syntheses. Because OpenMEE's statistical components are written in R, new methods and packages can be rapidly incorporated into the software. To fully realize the potential of OpenMEE, we encourage community development with an aim to advance the capabilities of meta-analyses in E\\&E.",10.1111/2041-210X.12708
+1627,InProceedings,A Case Study of Motivations for Corporate Contribution to FOSS,"Free/Open Source Software developers come from a myriad of different backgrounds, and are driven to contribute to projects for a variety of different reasons, including compensation from corporations or foundations. Motivation can have a dramatic impact on how and what contribution an individual makes, as well as how tenacious they are. These contributions may align with the needs of the developer, the community, the organization funding the developer, or all of the above. Understanding how corporate sponsorship affects the social dynamics and evolution of Free/Open Source code and community is critical to fostering healthy communities. We present a case study of corporations contributing to the Linux Kernel. We find that corporate contributors contribute more code, but are less likely to participate in non-coding activities.

+1628,InProceedings,A Clone Management Framework to Improve Code Quality of FOSS Projects,The emergence of Free/Open Source Software (FOSS) development model as a widely adopted paradigm in the software development industry in the recent few years has developed the interest of researchers towards the code quality of FOSS projects. Code clones are introduced in the software system by the adoption of common code reuse practices by FOSS developers. This has led the clone research community to observe the effects of code clones on the code quality of FOSS projects. Although code clones are not always harmful but they might become critical to large scale and evolving software systems such as FOSS projects. Research in this paper reveals the importance and need for improving code quality of FOSS projects by implementing an effective clone management system integrated in the FOSS development environment. This paper proposes a clone management framework that ensures effective clone evolution tracking and visualization in FOSS projects. This framework will appear as a baseline to initiate the efforts towards improving code quality by the implementation of a versatile clone management system for FOSS development.,NA

This is a very costly activity. A lot of time, effort and resources can be saved if the defects can be predicted beforehand, using a suitable training data set. For this, the generation of defect reports which reports the classes that are defective and computes the required software metrics is required. This process should be fully automated. Various data analysis research techniques and algorithms can be applied on this produced data set and this information can be very helpful for the developers and the organization as a whole for the prediction of bugs for future purposes and for analysis of the quality of the software being produced. The various issues addressed in this paper are (1) selection of suitable projects as input for the tool, (2) a mechanism to trace the whole project code history and identifying the classes present, (3) the criteria for classifying a class as defective, (4) method to generate most accurate software metrics for the classes, (5) combining all the data into a final representable format.

Most of the existing software applications are nowadays distributed as Package-based Free and Open Source (PFOS) applications. Different requirements must be considered while configuring PFOS software. These requirements can be classified into two classes: dependency and capacity requirements.In this paper, we proposed a novel approach to ensure the correctness of elastic composite PFOS applications. Our approach is based on Event-B and combines proof-based models with model checking to provide a more complete verification. It starts by abstractly specifying the main concepts of PFOS software, and then refining them through multiple steps to model the elastic composite PFOS software and its correctness requirements. The consistency of each model and the relationship between an abstract model and its refinements are obtained by formal proofs.

Drawing from a case study focusing on the deployment and operation phases of the DHIS2 platform in Malawi, we observe open source software platforms require a range of human resource capacities that go beyond capacity to use the platform. To fully leverage open source health information software platforms entails the availability of platform usage capacity, platform deployment capacity, platform customisation capacity and platform module development capacity. Most capacity building initiatives for information systems in developing countries have been short-term efforts focused on initial end user capacity to use such systems. However, to cope with rapid innovations and evolution associated with open source software platforms, capacity building ought to be a continuous process encompassing a range of human resource capacities not only use of the platform.",10.1007/978-3-319-59111-7\\_8

+1636,Article,A large-scale study of architectural evolution in open-source software systems,"From its very inception, the study of software architecture has recognized architectural decay as a regularly occurring phenomenon in long-lived systems. Architectural decay is caused by repeated, sometimes careless changes to a system during its lifespan. Despite decay's prevalence, there is a relative dearth of empirical data regarding the nature of architectural changes that may lead to decay, and of developers' understanding of those changes. In this paper, we take a step toward addressing that scarcity by introducing an architecture recovery framework, ARCADE, for conducting large-scale replicable empirical studies of architectural change across different versions of a software system. ARCADE includes two novel architectural change metrics, which are the key to enabling large-scale empirical studies of architectural change. We utilize ARCADE to conduct an empirical study of changes found in software architectures spanning several hundred versions of 23 open-source systems. Our study reveals several new findings regarding the frequency of architectural changes in software systems, the common points of departure in a system's architecture during the system's maintenance and evolution, the difference between system-level and component-level architectural change, and the suitability of a system's implementation-level structure as a proxy for its architecture.",10.1007/s10664-016-9466-0

Wemyss's most monstrous actions suggest an atavistic patriarchal dominance like the hereditary reversion theorized by Samuel Butler as unconscious memory. Wemyss brings up the issue of England's inheritance, and a disturbing vision dawns as the philistine and self-appointed natural man subdues Lucy. Daphne du Maurier's Rebecca (1938) follows Vera's plot, but it does not interrogate naturalness in the same way. Entrapped in her husband's vision of a natural woman, the narrator registers Rebecca's wild transgressiveness as more powerful and universal than her own tamed naturalness.",10.1080/09574042.2017.1320072
+1639,Article,All That Is Solid Turns into Steam: Sublimation and Sympathy in George Eliot's The Mill on the Floss,"This essay argues that steam and its gaseous properties in George Eliot's The Mill on the Floss (1861) represent capital's increasing abstraction in the nineteenth century that threatened to disrupt economic and affective relations between people, property, and places associated with the past while nevertheless introducing new modes of circulation and more diffusive opportunities for sympathetic connection. The novel's return to an earlier stage in the development of capital places the 1830s of the story in dialogue with the 1860s of its narration, while inviting readers to compare the values of this earlier period to those of their own. Considering this comparative structure in relation to nineteenth-century ethnography and its interlocutors-including Auguste Comte, Ludwig Feuerbach, and Karl Marx-I read Edward Tulliver's primitive materialism and the Dodson sisters' fetishism as both humorous reactions and more earnest forms of resistance to this increasing abstraction. Eliot ultimately turns toward the figurative possibilities of sublimation as a way to bridge the concrete and the abstract, the particular and the general, will and affect, self and other. Sublimation-not liquidation-therefore serves as the more apt metaphor for sympathy in the novel.",10.1525/ncl.2017.72.3.338
+1640,InProceedings,An Approach Based on Structural Differences to Expedite Applying OSS updates to Products,"Open source software (OSS)-based product development takes advantage of feature updates and bug fixes from OSS communities. However, when we customize the OSS and do not return the changes back to the OSS communities, our customization and the updates sometimes conflict. That makes it difficult to apply forthcoming OSS updates since we need to grasp the software changes appropriately. We propose a method to visualize software's structural differences using call graph. We have applied the method to a product development process and found that our method helps developers to speed up the application of OSS updates and reduce update errors. We have also found that solely providing call graph is insufficient for them to check the differences. They need more detailed information, e.g. data flow, as well as a guide to utilize the difference information to resolve the conflicts.",10.1109/COMPSAC.2017.51
+1641,InProceedings,An Empirical Analysis of Build Failures in the Continuous Integration Workflows of Java-Based Open-Source Software,"Continuous Integration (CI) has become a common practice in both industrial and open-source software development. While CI has evidently improved aspects of the software development process, errors during CI builds pose a threat to development efficiency. As an increasing amount of time goes into fixing such errors, failing builds can significantly impair the development process and become very costly. We perform an in-depth analysis of build failures in CI environments. Our approach links repository commits to data of corresponding CI builds. Using data from 14 open-source Java projects, we first identify 14 common error categories. Besides test failures, which are by far the most common error category (up to >80\\% per project), we also identify noisy build data, e.g., induced by transient Git interaction errors, or general infrastructure flakiness. Second, we analyze which factors impact the build results, taking into account general process and specific CI metrics. Our results indicate that process metrics have a significant impact on the build outcome in 8 of the 14 projects on average, but the strongest influencing factor across all projects is overall stability in the recent build history. For 10 projects, more than 50\\% (up to 80\\%) of all failed builds follow a previous build failure. Moreover, the fail ratio of the last k=10 builds has a significant impact on build results for all projects in our dataset.",10.1109/MSR.2017.54

Objective: In this paper, we present ongoing work aimed at analyzing the content of forum posts of a hybrid open source company that offers both free and commercial licenses, in order to help its community manager gain improved understanding of the forum discussions and sentiments and automatically discover new opportunities such as sales leads, i.e., people who are interested in buying a license. These leads can then be forwarded to the sales team for follow-up and can result in them potentially making a sale, thus increasing company revenue. Method: For the analysis of the forums, an untapped channel for sales leads by the company, text analysis techniques are utilized to identify potential sales leads and the discussion topics and sentiments in those leads. Results: Results of our preliminary work make a positive contribution in lessening the community manager's work in understanding the sentiment and discussion topics in the hybrid open source forum community, as well as make it easier and faster to identify potential future customers. Conclusion: We believe that the results will positively contribute to improving the sales of licenses for the hybrid open source company.",10.1109/ESEM.2017.52

Numerous studies have extensively investigated how knowledge is acquired in these environments through a collaborative learning model that define a learning process. Such a learning process, identified either as a result of surveys or by means of questionnaires, can be depicted through a series of graphical representations indicating the steps FLOSS community members go through as they acquire and exchange skills. These representations are referred to as a-priori learning models. They are Petri net-like workflow nets (WF-net) that provide a visual representation of the learning process as it is expected to occur. These models are representations of a learning framework or paradigm in FLOSS communities. As such, the credibility of any models is estimated through a process of model verification and validation. Therefore in this paper, we analyze these models in comparison with the real behavior captured in FLOSS repositories by means of conformance verification in process mining. The purpose of our study is twofold. Firstly, the results of our analysis provide insights on the possible discrepancies that are observed between the initial theoretical representations of learning processes and the real behavior captured in FLOSS event logs, constructed from mailing archives. Secondly, this comparison helps foster the understanding on how learning actually takes place in FLOSS environments based on empirical evidence directly from the data.",10.1007/s10639-017-9573-6
+1649,Article,Analysing change profiles of open source software projects using burst detection,"Software evolution refers to the phenomenon of continuous software change and growth after its initial development. A version control system records all information about these changes. Several research studies in the past have studied the historical records of changes of open source software (OSS) projects and found them useful for understanding the software evolution process. However, most of them investigate the distributions of changes types, change size, and change effort in an isolated manner. There is no work, to the best of our knowledge, which takes a combined view of various dimensions of a change. This study examines the change activity in 106 OSS projects from three points of view: change purpose (type), change size, and change effort. The common patterns in change type, change size, and change effort are highlighted using the burst detection technique. The burst detection technique helps in identifying the peaks in the time series and compares them with the peaks of other time series. The results indicate that the change-type activity of OSS projects is significantly related with change effort, and change size for high and moderate-activity clusters. Though for low-activity cluster, this commonality of patterns is not there for all types of changes.",10.1049/iet-sen.2016.0130

A Comparison to Core and Periphery Developers in FLOSS Repositories,"Context: Free/Libre Open Source Software (FLOSS) communities consist of different types of contributors. Core contributors and peripheral contributors work together to create a successful project, each playing a different role. One-Time Contributors (OTCs), who are on the very fringe of the peripheral developers, are largely unstudied despite offering unique insights into the development process. In a prior survey, we identified OTCs and discovered their motivations and barriers. Aims: The objective of this study is to corroborate the survey results and provide a better understand of OTCs. We compare OTCs to other peripheral and core contributors to determine whether they are distinct. Method: We mined data from the same code-review repository used to identify survey respondents in our previous study. After identifying each contributor as core, periphery, or OTC, we compared them in terms of patch size, time interval from submission to decision, the nature of their conversations, and patch acceptance rates. Results: We identified a continuum between core developers and OTCs. OTCs create smaller patches, face longer time intervals between patch submission and rejection, have longer review conversations, and face lower patch acceptance rates. Conversely, core contributors create larger patches, face shorter time intervals for feedback, have shorter review conversations, and have patches accepted at the highest rate. The peripheral developers fall in between the OTCs and the core contributors. Conclusion: OTCs do, in fact, face the barriers identified in our prior survey. They represent a distinct group of contributors compared to core and peripheral developers.",10.1109/ESEM.2017.7

In Indonesia alone, 25\\% of South East Asia's mangroves are at a risk. The continued decline in mangrove forest induced by anthropogenic activity has made all the stakeholders who have the concern at the mangrove forest preservation worried, including the government. There were several programs have been performed by the government to preserve the mangrove forest. One of the programs was ``Mangrove Rehabilitation Program in three districts: Ciamis, Indramayu, and Subang{''} held by Forestry Department of West Java Province in 2007. The aims of this study were to assess the changes in mangrove forest area before the program performed and to evaluate the successfulness of the program, using the increasing of mangrove forest area as a parameter. This study was conducted only in Subang and Indramayu Districts of West Java, Indonesia. The assessment was conducted using Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8 OLI acquired in 1996, 2006, and 2016 respectively. For each image, a supervised classification method was performed using open source GRASS GIS software. The resulting maps were then compared to quantify the changes. Field work activity conducted and confirmed the changes that occurred in the study areas. Our study shows that all of the two districts exhibit successfulness of the plantation program. Ground truth survey confirmed that the successfulness of the plantation program is due to the participation of communities in the area of study.

+1658,Article,Automating the license compatibility process in open source software with SPDX,"Free and Open Source Software (FOSS) promotes software reuse and distribution at different levels for both creator and users, but at the same time imposes some challenges in terms of FOSS licenses that can be selected and combined. The main problem linked to this selection is the presence of a large set of licenses that define different rights and obligations in software use. The problem becomes more evident in cases of complex combinations of software that carries different - often conflicting - licenses. In this paper we are presenting our work on automating license compatibility by proposing a process that examines the structure of Software Package Data Exchange (SPDX) for license compatibility issues assisting in their correct use and combination. We are offering the possibility to detect license violations in existing software projects and make suggestions on appropriate combinations of different software packages. We are also elaborating on the complexity and ambiguity of licensing detection in software products through representative case studies. Our work constitutes a useful process towards automating the analysis of software systems in terms of license use and compatibilities. (C) 2016 Elsevier Inc.

+1659,Article,AxonPacking: An Open-Source Software to Simulate Arrangements of Axons in White Matter,"Quantitative Magnetic Resonance Imaging (MRI) can provide parameters that describe white matter microstructure, such as the fiber volume fraction (FVF), the myelin volume fraction (MVF) or the axon volume fraction (AVF) via the fraction of restricted water (fr). While already being used for clinical application, the complex interplay between these parameters requires thorough validation via simulations. These simulations required a realistic, controlled and adaptable model of the white matter axons with the surrounding myelin sheath. While there already exist useful algorithms to perform this task, none of them combine optimisation of axon packing, presence of myelin sheath and availability as free and open source software. Here, we introduce a novel disk packing algorithm that addresses these issues. The performance of the algorithm is tested in term of reproducibility over 50 runs, resulting density, and stability over iterations. This tool was then used to derive multiple values of FVF and to study the impact of this parameter on fr and MVF in light of the known microstructure based on histology sample. The standard deviation of the axon density over runs was lower than 10(-3) and the expected hexagonal packing for monodisperse disks was obtained with a density close to the optimal density (obtained: 0.892, theoretical: 0.907). Using an FVF ranging within {[}0.58, 0.82] and a mean inter-axon gap ranging within {[}0.1, 1.1] mu m, MVF ranged within {[}0.32, 0.44] and fr ranged within {[}0.39, 0.71], which is consistent with the histology. The proposed algorithm is implemented in the open-source software AxonPacking (hups://github.comineuropoly/ axonpacking) and can be useful for validating diffusion models as well as for enabling researchers to study the interplay between microstructure parameters when evaluating qMRI methods.",10.3389/fninf.2017.00005

While the requirements and benefits of data exchange are widely discussed, there are few proposals on how to implement data platforms that not only permit the exchange of research data among researchers, but also permit to distribute research results and data to the interest public. We elaborate what points are important for implementing a (geographic) data repository and propose then to adopt the concept of Spatial Data Infrastructures (SDI) as a solution for the implementation of research data repositories. We present as a case study the geographic data and document repository of the Chilean research Centre on Sustainable Urban Development (CEDEUS), the CEDEUS Observatory. Besides the infrastructure to host and distribute data, communication tools are an important component of such a data repository service.

To do this, I begin by striking a dialectic between John Milbank's theological and David Graeber's anthropological conceptions of gift economies, illuminating crucial aspects of each to uncover what alternative economic principles are applicable to standard capitalist economic ideologies. I then turn to a practical application of where these gift economy ideologies are already being utilized to a degree, arguing specifically that open source software provides an alternative economic logic for countless members of the technology sector. On a broad level, I hope to show that capitalism provides the means to alter itself within its own ethos, as certain economic ideologies like gift economies - could potentially assuage those economic models that contribute to economic inequality. By accentuating these alternative logics within technology firms, they can be expanded and made more substantial, subsequently altering capitalism from the inside out.",10.1179/1462317X15Z.000000000146

The stability and longevity of this group of most active developers are crucial for the success of the project. While there has been prior work on identifying key individuals in open source development, little attention has been devoted to the identification of cross-cutting core individuals (boundary spanners) whose responsibilities span across different functional areas of open source development (e.g., who are involved both in development-centric activities and user-centric activities). To address this gap, we propose an approach to identify the core cross-cutting members and their roles within the community through analyzing email communication repositories. We use Social Network Analysis (SNA) tools to identify the most active core members in different forums (that have different focus such as Python-dev that focuses on language evolution and Python Lists that focus on user support), and their activities over time, thus identifying the core developers and their involvement in different community mailing lists. Based on the involvement of a core developer and the overall social structure of the network of core developers, we also present an approach for identifying a potential replacement for a community administrator that steps down. Using email repositories of six main Python forums as the case study domain, we computed several social network analysis metrics to characterize the core developers and their importance in the Python community.",10.1109/APSEC.2017.37

Celeris is an open source software which needs minimum preparation to run on a Windows machine. The software solves the extended Boussinesq equations using a hybrid finite volume finite difference method and supports moving shoreline boundaries. The simulation and visualization are performed on the GPU using Direct3D libraries, which enables the software to run faster than real-time. Celeris provides a first-of-its-kind interactive modeling platform for coastal wave applications and it supports simultaneous visualization with both photorealistic and colormapped rendering capabilities. We validate our software through comparison with three standard benchmarks for non-breaking and breaking waves. Program summary Program title: Celeris Program Files doi: http://dx.doi.org/10.17632/5djwvf5x5k.1 Licensing provisions: GNU General Public License 3 (GPL) Programming language: C++, HLSL Nature of problem: Boussinesq-type models provide the research-level accuracy needed for modeling wave propagation in coastal zones. However the current models, both commercial and open source, do not provide means for real-time computation, nor provide model interactivity and concurrent visualization. In order to achieve a real-time simulation speed in current parallelized models, dozens to hundreds of CPU cores are needed. Celeris is an interactive software which provides faster than real-time simulation and visualization speed on an average user laptop. The novelty of this software is its interactive environment, which allows the user to modify the model and field parameters as the model is running, and to see the effect of these changes immediately. Solution method: A hybrid finite volume-finite difference scheme is used to solve the extended Boussinesq equations. The solver is parallelized using shader programming with Direct3D libraries. Visualization is also performed with the same libraries. (C) 2017 Elsevier B.V. All rights reserved.",10.1016/j.cpc.2017.03.002

+1668,Article,Changes in free and open source software licenses: managerial interventions and variations on project attractiveness,"The license adopted by an open source software is associated with its success in terms of attractiveness and maintenance of an active ecosystem of users, bug reporters, developers, and sponsors because what can and cannot be done with the software and its derivatives in terms of improvement and market distribution depends on legal terms there specified. By knowing this licensing effect through scientific publications and their experience, project managers became able to act strategically, loosening up the restrictions associated with their source code due to sponsor interests, for example; or the contrary, tightening restrictions up to guarantee source code openness, adhering to the ``forever free{''} strategy. But, have project managers behaved strategically like that, changing their projects license? Up to this paper, we did not know if and what types of changes in these legal allowances project managers have made and, more importantly, whether such managerial interventions are associated with variations in intervened project attractiveness (i.e., related to their numbers of web hits, downloads and members). This paper accomplishes these two goals and demonstrates that: 1) managers of free and open source software projects do change the distribution rights of their source code through a change in the (group of) license(s) adopted; and 2) variations in attractiveness are associated with the strategic choice of a licensing schema. To reach these conclusions, a unique dataset of open source projects that have changed license was assembled in a comparative form, analyzing intervened projects over its monthly periods of different licenses. Based on a sample of more than 3500 active projects over 44 months obtained from the FLOSSmole repository of Sourceforge.net, 756 projects that had changed their source code distribution allowances and restrictions were identified and analyzed. A dataset on these projects' type of changes was assembled to enable a descriptive and exploratory analysis of the types of license interventions observed over a period of almost four years anchored on projects' attractiveness. More than 35 types of interventions were detected. The results indicate that variations in attractiveness after a license intervention are not symmetric; that is, if a change from license schema A to B is beneficial to attractiveness, a change from B to A is not necessarily prejudicial. This and other interesting findings are discussed in detail. In general, the results here reported support the current literature knowledge that the restrictions imposed by the license on the source code distribution are associated with market success vis-a-vis project attractiveness, but they also suggest that the state-of-the-science is superficial in terms of what is known about why these differences in attractiveness can be observed. The complexity of the results indicates to free software managers that no licensing schema should be seen as the right one, and its choice should be carefully made, considering project strategic goals as perceived relevant to stakeholders of the application and its production. These conclusions create awareness of several limitations of our current knowledge, which are discussed along with guidelines to understand them deeper in future research endeavors.",10.1186/s13174-017-0062-3

Their underlying technical interests, expertise, and working habits are indirectly delineated by their personal contributions. This paper is to discover the individualized contribution features of developers by latent Dirichlet allocation (LDA) approach. Dominant latent topics of each developer and the corresponding topic coverage degree are extracted from the source codes committed to the project repository, and such topic model is validated to be feasible for representing the individualized contribution features by statistics tests. Four types of topic evolution patterns are observed from the commit history of a developer. Temporal locality is partially exhibited in the topic evolution but there usually exhibit drastic changes between time-adjacent contributions of a developer. Respective proportions of the four evolution patterns and the degree of temporal locality in the topic evolution delineate a developer's individualized working habits in the time dimension. It is also proved that the correlation among the topic models of different developers is not equivalent to the real social collaborations among them. The outcome of this study would help OSS project coordinators get deep understanding on the work preferences and behavioral patterns of team members, thus facilitate project coordination activities such as task allocations.",10.1142/S021819401750005X

CoRain is a free and open source software written in R language that could greatly help analyzing inhomogeneity caused by rainfall measuring instruments. CoRain compares two parallel rain series (with an overlapping period) and tries to highlight overestimations and underestimations due to rain gauges in a specific condition, so that the user can consider it for future analysis. CoRain offers many information on the two analyzed series, starting with cleaning input data, comparing them and classifying rainy days by severity. CoRain is a cross-platform software, easily adaptable to different needs, that takes in input a single text file with daily information of the two rain series and outputs tables (in CSV format) and plots (as PNG images) that help in the interpretation of the data.

+1672,InProceedings,Community Engagement with Free and Open Source Software,"A common refrain from Senior Exit Surveys and Alumni Surveys is the desire to work on ""real-world,"" ""practical"" and ""hands-on"" projects using industry-ready tools and development environments. To assuage this, institutions have moved towards adopting Free and Open Source Software (FOSS) as an avenue to provide meaningful, applied learning interventions to students. Through these experiences, students benefit from engagement with various communities including: the community of contributors to the FOSS project; the community of local software developers; the community of citizens who reside in the local area; the community of students at their institution and others; and, the community of people impacted by the FOSS project. These engagements motivate students, enhance their communication and technical skills, allow them to grow and become more confident, help them form professional networks, and provide the ""real-world"" projects they seek. In this panel, we will discuss our experiences in engaging students with five different types of communities as part of incorporating FOSS into our courses, focusing on how other educators can provide the same benefits to their students as well. In order to satisfy the time constraints of the panel, the last two authors will present together.",10.1145/3017680.3017682

However, careers in software engineering demand learning how to work within a professional environment and how to follow software development processes. We studied the impact of students' interactions with external collaborators on open source projects and found many similar outcomes between those who communicated remotely and those who communicated face-to-face. However, we also discovered that face-to-face interactions with local software professionals following the Localized Free and Open Source (LFOSS) model had particular advantages in teaching Agile methods, holding students accountable, and introducing professional networking opportunities.",10.1145/3059009.3059019
+1676,Article,Construction and utilization of problem-solving knowledge in open source software environments,"Open Source Software (OSS) has become an important environment where developers can share reusable software assets in a collaborative manner. Although developers can find useful software assets to reuse in the OSS environment, they may face difficulties in finding solutions to problems that occur while integrating the assets with their own software. In OSS, sharing the experiences of solving similar problems among developers usually plays an important role in reducing problem-solving efforts. We analyzed how developers interact with each other to solve problems in OSS, and found that there is a common pattern of exchanging information about symptoms and causes of a problem. In particular, we found that many problems involve multiple symptoms and causes and it is critical to identify those symptoms and causes early to solve the problems more efficiently. We developed a Bayesian network based approach to semiautomatically construct a knowledge base for dealing with problems, and to recommend potential causes of a problem based on multiple symptoms reported in OSS. Our experiments showed that the approach is effective to recommend the core causes of a problem, and contributes to solving the problem in an efficient manner. (C) 2016 Elsevier Inc.

+1677,Article,Continued Voluntary Participation Intention in Firm-Participating Open Source Software Projects,"Firm participation in open source software (OSS) development is a noteworthy phenomenon and includes two types of firm-participating OSS projects: community founded (developed from an open project) and spinout (spun out from an information technology firm's internal project). OSS project leaders implement quality controls to improve the quality of developed products. They may not be aware that their implementation of quality controls produces a side effect-quality controls signal unobservable project quality to volunteers and promote volunteers' continued participation intentions (VCPI). We focus on two quality controls-accreditation and code acceptance, which, respectively, map to the input and output quality of an OSS project-and compare their respective effects on VCPI in community-founded and spinout projects. We propose that accreditation and code acceptance influence VCPI by signaling unobservable input and output quality to volunteers. As we focus on continued participation, we theorize as to how volunteers' tenure in OSS projects moderates the relationships between the signaling effects of input and output quality controls and VCPI. Furthermore, we theorize as to how the OSS project type moderates the effects of quality controls on VCPI. We surveyed 304 volunteers from 40 OSS projects and constructed a two-level model of project and developer factors to explain VCPI. Our findings indicate that both accreditation and code acceptance enhance VCPI. The signaling effects on VCPI associated with accreditation decline with volunteer tenure, but those associated with code acceptance do not. Accreditation and code acceptance influence VCPI, with community-founded projects exhibitingweaker direct positive effects and spinout projects exhibiting stronger direct positive effects. We discuss the theoretical and practical implications of these findings.",10.1287/isre.2016.0687

On this rationale, this study was carried out to explore the applicability of the concept of converging `Free and Open Source Software (FOSS)' to promote sustainable knowledge sharing amongst the agricultural communities in Sri Lanka. A multi-stage community consultative process with a set of designated officials ({''}Sponsors{''}) and a series of semi-structured questionnaire survey with a cross section of smallholder agriculture farmers (n=246), were carried out in the Batticaloa, Kurunegala and Puttalam districts to gather the baseline data. This was followed by a number of field experiments ({''}Campaigns{''}) with the farmers (n=340) from same geographical areas. The two FOSS, namely: (1) ``FrontlineSMS{''} for `Text Messaging' and (2) ``FreedomFone{''} for `Interactive Voice Responses', were applied to evaluate the effectiveness of knowledge sharing within the farming communities. It was found that FOSS intervention increases the `Text messaging' and `Voice Call' usage in day-to-day agricultural communication by 26 and 8 percent, respectively. The demographic factors like age and educational level of the farmers have a positive influence on the knowledge sharing process. And also the `Mobile Telephony' was the most extensive mode of communication within the communities. The outcome of analysis, as a whole, implies that, with a fitting mechanism in place, this approach can be promoted as a ``drive for positive changes{''} in agriculture-based rural communities in developing countries like Sri Lanka, and those in South and East Asia with similar socioeconomic and cultural perspectives.",10.12895/jaeid.20172.649

Participation in an open and independent environment also implies the competition among firms with similar business models and targeted markets. Hence, firms need to consider potential opportunities and challenges upfront. This study explores how software firms interact with others in OSS ecosystems from a coopetition perspective. We performed a quantitative and qualitative analysis of three OSS projects. Finding shows that software firms emphasize the co-creation of common value and partly react to the potential competitiveness on OSS ecosystems. Six themes about coopetition were identified, including spanning gatekeepers, securing communication, open-core sourcing and filtering shared code. Our work contributes to software engineering research with a rich description of coopetition in OSS ecosystems. Moreover, we also come up with several implications for software firms in pursing a harmony participation in OSS ecosystems.",10.1007/978-3-319-69191-6\\_10

The study uses data from 74 projects in the Apache Software Foundation Incubator. We conceptualize project success in terms of success building a community, as assessed by graduation from the Incubator. We compare successful and unsuccessful projects on volume of communication and on use of inclusive pronouns as an indication of efforts to create intimacy among team members. An innovation of the paper is that use of inclusive pronouns is measured using natural language processing techniques. We also compare the volume and content of communication produced by core (committer) and peripheral members and by those peripheral members who are later elected to be core members. We find that volume of communication is related to project success but use of inclusive pronouns does not distinguish successful projects. Core members exhibit more contribution and use of inclusive pronouns than peripheral members.",10.1186/s13174-017-0061-4

The case of collaborative OSS communities,"Purpose - This paper aims to present that deliberate change is strongly associated with formal structures and top-down influence. Hierarchical configurations have been used to structure processes, overcome resistance and get things done. But is deliberate change also possible without formal structures and hierarchical influence? Design/methodology/approach - This longitudinal, qualitative study investigates an open-source software (OSS) community named TYPO3. This case exhibits no formal hierarchical attributes. The study is based on mailing lists, interviews and observations. Findings - The study reveals that deliberate change is indeed achievable in a non-hierarchical collaborative OSS community context. However, it presupposes the presence and active involvement of informal change agents. The paper identifies and specifies four key drivers for change agents' influence. Originality/value - The findings contribute to organisational analysis by providing a deeper understanding of the importance of leadership in making deliberate change possible in non-hierarchical settings. It points to the importance of ``change-by-conviction{''}, essentially based on voluntary behaviour. This can open the door to reducing the negative side effects of deliberate change also for hierarchical organisations.",10.1108/IJOA-08-2016-1050
+1685,Article,Developer Role Evolution in Open Source Software Ecosystem: An Explanatory Study on GNOME,"An open source software (OSS) ecosystem refers to an OSS development community composed of many software projects and developers contributing to these projects. The projects and developers co-evolve in an ecosystem. To keep healthy evolution of such OSS ecosystems, there is a need of attracting and retaining developers, particularly project leaders and core developers who have major impact on the project and the whole team. Therefore, it is important to figure out the factors that influence developers' chance to evolve into project leaders and core developers. To identify such factors, we conducted a case study on the GNOME ecosystem. First, we collected indicators reflecting developers' subjective willingness to contribute to the project and the project environment that they stay in. Second, we calculated such indicators based on the GNOME dataset. Then, we fitted logistic regression models by taking as independent variables the resulting indicators after eliminating the most collinear ones, and taking as a dependent variable the future developer role (the core developer or project leader). The results showed that part of such indicators (e.g., the total number of projects that a developer joined) of subjective willingness and project environment significantly influenced the developers' chance to evolve into core developers and project leaders. With different validation methods, our obtained model performs well on predicting developmental core developers, resulting in stable prediction performance (0.770, F-value).",10.1007/s11390-017-1728-9

However, does a larger commons automatically beget success or does the phenomenon fall prey to the tragedy of the commons? This research forwards and empirically investigates the curvilinear relationship between developers and OSS project quality and a project's download volume. Using segmented regression on over 12,000 SourceForge OSS projects, findings suggest an inflection point in the number of contributing developers on download volume - suggesting increasing and diminishing returns to scale from adding developers to OSS projects. Findings support the economic principle of the tragedy of the commons, a concept where an over-allocated (large number) of developers, even in an open-source environment, can lead to resource mismanagement and reduce the benefit of a public good, i.e. the OSS project.",10.4018/JOEUC.2017040103

+1692,Article,Empirical analysis of search based algorithms to identify change prone classes of open source software,"There are numerous reasons leading to change in software such as changing requirements, changing technology, increasing customer demands, fixing of defects etc. Thus, identifying and analyzing the change-prone classes of the software during software evolution is gaining wide importance in the field of software engineering. This would help software developers to judiciously allocate the resources used for testing and maintenance. Software metrics can be used for constructing various classification models which can be used for timely identification of change prone classes. Search based algorithms which form a subset of machine learning algorithms can be utilized for constructing prediction models to identify change prone classes of software. Search based algorithms use a fitness function to find the best optimal solution among all the possible solutions. In this work, we analyze the effectiveness of hybridized search based algorithms for change prediction. In other words, the aim of this work is to find whether search based algorithms are capable for accurate model construction to predict change prone classes. We have also constructed models using machine learning techniques and compared the performance of these models with the models constructed using Search Based Algorithms. The validation is carried out on two open source Apache projects, Rave and Commons Math. The results prove the effectiveness of hybridized search based algorithms in predicting change prone classes of software. Thus, they can be utilized by the software developers to produce an efficient and better developed software. (C) 2016 Elsevier Ltd. All rights reserved.",10.1016/j.cl.2016.10.001

Method and Result: A 77-year-old woman with a non-healing anteromedial chest wound presented with sudden hypotension and hemoptysis. The computed tomography (CT) scan revealed a 9-cm-diameter pseudoaneurysm of ascending aorta, with sternal erosion close to the wound. Conventional open repair was not preferred due to possible contamination of interposition graft and difficult sternum closure. The feasibility of endografting was confirmed based on appropriate landing zones. After endografts modification at back table, we made a left minithoracotomy and establish a through-and-through body floss wire from left ventricular apex to femoral artery. Retrograde delivery over this wire from femoral artery to ascending aorta and deployment of endografts under rapid ventricular pacing support were performed smoothly. Final angiography showed no endoleaks with patent coronary and arch vessels. Further wound debridement was done at the same time and wound culture yielded tuberculosis. After completing anti-tuberculosis therapy, no recurrent infection occurred. Postoperative 6-month CT scan disclosed optimal result. Conclusion: With adequate landing zones and delicate surgical strategy, endografting with anti-tuberculosis therapy may be an alternative treatment for ascending aortic tuberculosis pseudoaneurysm.",10.1016/j.avsg.2017.07.026
+1694,InProceedings,Estimating Reliability for OSS: An approach with Change-point in Operational Phase,"Software reliability growth models (SRGMs) proposed on the foundations of Non-Homogenous Poisson Process (NHPP) have been the most accepted way to analyze reliability growth of a software since 1970's. Henceforth, Literature witnesses the evolution of SRGMs in terms of different assumptions, parameters, performance etc. This study is an attempt to model reliability growth phenomenon for Open Source Software (OSS). As the development process followed by OSS significantly differs from proprietary software, traditional software engineering SDLC models can't be followed for its development. OSS development procedure does not incorporate a dedicated testing phase and therefore negligible effort expenditure is done on testing of software prior its release. The volume of volunteer participation in its operational phase thus becomes a significant criterion in the representation of its reliability growth. Also, the impact of sudden changes in fault detection process (change-point) due to several reasons like variations in fault density, irregular team size, volunteer expertise etc is captured in proposed SRGM. This paper suggests a reliability model based on user growth with the concept of change point to better cater the heterogeneity in software failure process. Failure data of GNOME 2.0 is used in this paper reliability growth analysis. Unknown parameters are estimated using Least Square Estimation regression technique. Performance inspection of proposed SRGM is carried out using goodness-of-fit criteria like Mean square error (MSE), Coefficient of Determination (R-2), Predictive Ratio Risk (PRR), and Predictive Power (PP). The study recommends that introduction of the change-point in SRGM improves prediction capability of the model and hence establishes an evidence of its applicability.",NA

The extracted cellulose had mainly a-cellulose as the other components hemicellulose and lignin were significantly removed during cellulose extraction process. The FTIR spectra also indicated that the chemical treatments extensively removed hemicellulose and lignin from the pristine milkweed floss. SEM technique was used to investigate the surface morphology of the pristine milkweed floss and extracted cellulose. The intensity of the crystalline peak in the X-ray diffractograms of the extracted cellulose was higher than that of pristine milkweed. Further, the XRD results indicated a structural transformation of cellulose I (pristine milkweed) to cellulose II (extracted cellulose) because of the chemical treatments.

In this paper, we introduce EyeRecToo, an open-source software for real-time pervasive head-mounted eye-tracking. Out of the box, EyeRecToo offers multiple real-time state-of-the-art pupil detection and gaze estimation methods, which can be easily replaced by user implemented algorithms if desired. A novel calibration method that allows users to calibrate the system without the assistance of a human supervisor is also integrated. Moreover, this software supports multiple head-mounted eye-tracking hardware, records eye and scene videos, and stores pupil and gaze information, which are also available as a real-time stream.

+1708,Article,Falcon: a highly flexible open-source software for closed-loop neuroscience,"Objective. Closed-loop experiments provide unique insights into brain dynamics and function. To facilitate a wide range of closed-loop experiments, we created an open-source software platform that enables high-performance real-time processing of streaming experimental data. Approach. We wrote Falcon, a C++ multi-threaded software in which the user can load and execute an arbitrary processing graph. Each node of a Falcon graph is mapped to a single thread and nodes communicate with each other through thread-safe buffers. The framework allows for easy implementation of new processing nodes and data types. Falcon was tested both on a 32-core and a 4-core workstation. Streaming data was read from either a commercial acquisition system (Neuralynx) or the open-source Open Ephys hardware, while closed-loop TTL pulses were generated with a USB module for digital output. We characterized the round-trip latency of our Falcon-based closed-loop system, as well as the specific latency contribution of the software architecture, by testing processing graphs with up to 32 parallel pipelines and eight serial stages. We finally deployed Falcon in a task of real-time detection of population bursts recorded live from the hippocampus of a freely moving rat. Main results. On Neuralynx hardware, round-trip latency was well below 1 ms and stable for at least 1 h, while on Open Ephys hardware latencies were below 15 ms. The latency contribution of the software was below 0.5 ms. Round-trip and software latencies were similar on both 32- and 4-core workstations. Falcon was used successfully to detect population bursts online with similar to 40 ms average latency. Significance. Falcon is a novel open-source software for closed-loop neuroscience. It has sub-millisecond intrinsic latency and gives the experimenter direct control of CPU resources. We envisage Falcon to be a useful tool to the neuroscientific community for implementing a wide variety of closed-loop experiments, including those requiring use of complex data structures and real-time execution of computationally intensive algorithms, such as population neural decoding/encoding from large cell assemblies.",10.1088/1741-2552/aa7526

Open source software is one of the representative examples of open collaboration. In this research, we examine the antecedents of innovation performance for open source software development organizations on Github (www.github.com), which is a leading web service for the open collaborations of developers. From the perspective of resource allocation, this study investigates effective governance strategies to allocate developers to multiple projects within an organization.

+1715,Article,Governing open source software through coordination processes,"Governance provides the authoritative framework for coordinating activities in open source development. Prior studies of open source governance have largely focused on its changing nature over time. In this work, we argue that the nature of governance varies across open source communities, and, in its evolution, multiple traces of authority may co-exist. We propose that such multiplicity can be understood by close examination of the authoritative structures embedded in coordination processes. We collected eight years of data on the coordination related to version control of the Linux kernel. Drawing on in-depth qualitative analysis, we investigate how coordination processes with different authoritative structures come together in the governance of open source software. We trace four coordination processes (autocratic clearing, oligarchic recursion, federated self-governance, and meritocratic idea-testing), each grounded in different authoritative structures (autocracy, oligarchy, federation, meritocracy) with their own form of legitimation. We offer a two-fold contribution in this paper. First, we enhance the open source governance literature by advancing a new theoretical perspective in which governance is seen as a configuration of coordination processes. Configurations give complementary support and are a source of tension and renewal. Second, we articulate a view on the conceptual relationship between governance and coordination where these concepts are understood as a duality, both working together to give rise to efficient and dynamic organizing in open source.",10.1016/j.infoandorg.2017.04.001
+1716,InProceedings,Healthcare Analytics and Visualization Using SEMantic Open Source Software (SEMOSS),"In the past year, 72\\% of Internet users have looked online for health information, indicating a high demand for online health information. This project seeks to help satisfy that demand by analyzing health data and designing a web portal to support patient healthcare decisions. The portal is powered by SEMantic Open Source Software (SEMOSS), an end-to-end analytics tool. The project aims to adapt SEMOSS's capabilities to make healthcare data accessible to the patient population and healthcare stakeholders. To achieve this goal, publiclyavailable data about doctors in the state of Virginia and hospitals across the United States was gathered. Visualizations were created to answer potential patient questions about doctors, such as which nearby practitioner has the most experience. Data from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, in conjunction with Census Bureau data, was explored. The census information facilitated classification of each hospital as urban or rural based on location. Multiple linear regression and random forest analysis were used to determine which elements of patient experience most influence whether a patient would recommend a hospital. Outputs from the multiple linear regression models indicated that of the statistically significant predictors, doctor communication and staff responsiveness most impacted recommendation scores in rural hospitals, and nurse communication and pain management were the most impactful for urban hospitals. Random forest analysis indicated that staff responsiveness and nurse communication were the most important variables in determining high or low recommendation scores for rural hospitals, and care transition and nurse communication were the most important variables for urban hospitals. These results will be used to create filtering options for the SEMOSS patient portal.",NA

It is particularly challenging in Free and Open Source Software (FOSS) ecosystems, in which hundreds of loosely connected developers and their projects are coordinated to release software to a schedule. To better understand this process and its challenges, we analyzed over two and half years of communication in the GNOME ecosystem and studied developers' interactions. Through a case study, we cataloged communication channels, determined the main channel from which we categorized high level communication and coordination activities spanning five releases, and triangulated our results by interviewing ten key developers. We found that a release schedule, influence (instead of direct control), and diversity are the main factors that positively impact the release process in the GNOME ecosystem. We report a set of lessons learned that encapsulates our understanding of how the Release Management process function in a FOSS ecosystem, we learned that: (1) ensure that the release team follows the main communication channels used by developers, (2) provide a common place for coordination for an ecosystem, (3) consider including both good technical and social skills in a release team, (4) aim for a diverse release team, (5) based on lack of power, lobbying and consensus based management must be followed, (6) help the release team in the coordination process with a well defined schedule, and (7) release team work is different from regular software work. Our results can help organizations build better large-scale teams and show that research focused on individual projects might miss important parts of the picture.",10.1186/s13174-017-0063-2

CI, in particular, is currently a standard development practice in open source software (OSS) projects. Although it is well-known that OSS contributors have different involvements (e.g., while some developers drive the project, there is a long tail of peripheral developers), little is known about how the contributor's degree of participation can influence the build status of an OSS project. Through TravisTorrent's dataset, we compare the success rates of builds made by casual and non-casual contributors and what factors on their contributions may influence the build result. Our results suggest that there is no representative difference between their build success (they are similar in 85\\% of the analyzed projects), meaning that being a casual contributor is not a strong indicator for creating failing builds. Also, factors like the size of their contributions and the number of project configurations (jobs) have the potential of impacting the build success.",10.1109/MSR.2017.32
+1719,Article,How do Open Source software companies respond to institutional pressures? A business model perspective,"Purpose - Open Source software companies (OSSCs) are confronted with institutional pressures from Open Source software (OSS) communities. They must find an acceptable balance between the expectations of these communities and their own business model. However, there are still few studies that try to analyse the OSSC business models. The purpose of this paper is to highlight OSSC typical business models by using rich empirical data. Design/methodology/approach - The methodology is based on a combination of quantitative analysis of a sample of 66 OSSCs and qualitative analysis of three typical situations resulting from that sample. Findings - The quantitative study enables the authors to highlight three typical business models. The in-depth study of three typical cases enables the authors to specify these OSSC business models. The authors can distinguish four key dimensions: the relationship developed with the OSS communities, the strategic manoeuvres made, the key resources and competitive positioning. Research limitations/implications - The results indicate that it is possible for firms to accommodate both profit and non-profit logics using different strategic manoeuvres to position themselves with regard to the Open Source institutional environment. Such accommodation requires the development of key resources and the adoption of suitable competitive positioning. Practical implications - This study allows the authors to highlight two main practical contributions for OSSCs' directors. First, the different manoeuvres identified may help them to ensure coherence between their strategic choices and the business model chosen. Second, the results can help OSSC founders identify value creation mechanisms more clearly by analysing four key variables. Originality/value - This paper provides new insight about OSSCs business models. It aggregates four dimensions that provide a more ``fine-grained{''} analysis of business models, while other studies often emphasise one dimension (usually the regime of appropriability).",10.1108/JEIM-05-2015-0041

Economics often pictures this phenomenon as a case of signalling: individuals engage in the volunteer programming of open-source software (OSS) as a labour-market signal resulting in a wage premium. Yet, this explanation could so far not be empirically tested. This article fills this gap by estimating an upper-bound composite wage premium of voluntary OSS contributions and by separating the potential signalling effect of OSS engagement from other effects. Although some 70\\% of OSS contributors believe that OSS involvement benefits their careers, we find no actual labour-market premium for OSS engagement. The presence of other motives, such as fun of play or altruism, renders OSS contributions too noisy to function as a signal.",10.1080/00036846.2016.1218427

+1729,Article,Legal aspects of ownership in modified open source software and its impact on Russian software import substitution policy,"In my previous publication, I tried to show how personal data legislation might be used for achieving the purposes of national sovereignty(1). In this paper, I will demonstrate how open source software may be used for achieving similar purposes. However, the interplay between local copyright law, public procurement law and open source community norms creates many issues relating to the legal status and ownership in modified software, based on open source. This is especially so in the case of so-called copyleft open source licenses, where a collision occurs between copyright, as an absolute right enforceable against the world, and the copyleft provisions of license agreements, which may be treated as ``rights in personam{''} enforceable only against the licensee. The exclusive right to derivative software as an independent object of copyright, may come into conflict with restrictions inherited from incoming copyleft licenses. This paper provides an overview and analysis of such problems faced by Russian software developers, attempting to comply with Russian import substitution provisions, by using open source components. Although it is based on Russian law, it may be applicable to other jurisdictions, since general aspects of copyright law and its interaction with private international law and contract law drive it. The paper concludes that the developer of software, containing code licensed under GEL or other copyleft provisions, receives full exclusive right to the derivative software and can commercialize it as he sees appropriate, subject only to possible claims of breach of contract rather than copyright infringement. This opens wide perspectives for using open source components regardless of the type of license used as bricks for building a de-globalized economy and society based on principles of information sovereignty.

A quantitative method with the analysis of 403 valid questionnaires is adopted. A series of hypotheses about how distributed innovation (independent variables) influences knowledge sharing (mediating variable) and then affects the performance of OSS projects (dependent variable) are tested and approved. On the one side, we argue that developers will actively affect knowledge sharing in terms of participative motivation, social network and organisational culture. On the other hand, users may also affect the knowledge sharing when considering innovation willingness and capacity. It is interesting to find that social network is the most important factor in Chinese cases.

Providing business strategy to benefit from volunteer developers for the purpose of contributing to existing projects, as well as initiating new OSS projects is of utmost significance for companies in that industry. Therefore, it is important to figure out how groups of volunteer developers are formed as new developers join existing projects, and it is even more important to investigate what causes these developers to initiate new projects. The authors investigate network structure as a causal factor for both new project initiation within a group (representing group innovation) as well as new developers joining existing projects within a group (representing group growth). The authors develop four hypotheses.1. Intra-group coupling has a positive impact on group growth, 2. Inter-group coupling has a positive impact on group innovation, 3. Inter-group structural hole has a positive impact on group innovation, 4. There is a trade-off between the effects of inter-group structural hole and inter-group coupling on group innovation.The authors test these four hypotheses using data from OSS. Developers contributing to project tasks in groups other than their own can explore novel ideas for new project creation, because they can benefit from sharing knowledge, whereas developers contributing to project tasks inside their own group exploit ideas to improve those existing projects with better inside-group search possibility; and this demands more developers to join those group projects.",10.21511/ppm.15(1).2017.01

+1737,Article,Open source software ecosystems: A Systematic mapping,"Context: Open source software (OSS) and software ecosystems (SECOs) are two consolidated research areas in software engineering. OSS influences the way organizations develop, acquire, use and commercialize software. SECOs have emerged as a paradigm to understand dynamics and heterogeneity in collaborative software development. For this reason, SECOs appear as a valid instrument to analyze OSS systems. However, there are few studies that blend both topics together. Objective: The purpose of this study is to evaluate the current state of the art in OSS ecosystems (OS-SECOs) research, specifically: (a) what the most relevant definitions related to OSSECOs are; (b) what the particularities of this type of SECO are; and (c) how the knowledge about OSSECO is represented. Method: We conducted a systematic mapping following recommended practices. We applied automatic and manual searches on different sources and used a rigorous method to elicit the keywords from the research questions and selection criteria to retrieve the final papers. As a result, 82 papers were selected and evaluated. Threats to validity were identified and mitigated whenever possible. Results: The analysis allowed us to answer the research questions. Most notably, we did the following: (a) identified 64 terms related to the OSSECO and arranged them into a taxonomy; (b) built a genealogical tree to understand the genesis of the OSSECO term from related definitions; (c) analyzed the available definitions of SECO in the context of OSS; and (d) classified the existing modelling and analysis techniques of OSSECOs. Conclusion: As a summary of the systematic mapping, we conclude that existing research on several topics related to OSSECOs is still scarce (e.g., modelling and analysis techniques, quality models, standard definitions, etc.). This situation calls for further investigation efforts on how organizations and OSS communities actually understand OSSECOs. (C) 2017 Elsevier B.V. All rights reserved.",10.1016/j.infsof.2017.07.007

Previously developed automated methods are often reliant on ad hoc rules that may not be transferable between different imaging modalities or retinal locations. In this work, we present a convolutional neural network (CNN) based method for cone detection that learns features of interest directly from training data. This cone-identifying algorithm was trained and validated on separate data sets of confocal and split detector AOSLO images with results showing performance that closely mimics the gold standard manual process. Further, without any need for algorithmic modifications for a specific AOSLO imaging system, our fully-automated multi-modality CNN-based cone detection method resulted in comparable results to previous automatic cone segmentation methods which utilized ad hoc rules for different applications.

For that to happen an accurate, robust and reliable method for structural monitoring is needed. GNSS with its advanced augmentation techniques can give a positioning accuracy in order of millimetres at its best. Such a higher order of accuracy can be used for precise structural deformation monitoring. Apart from that GNSS gives us loathsome advantages like all weather, around the clock and global coverage. GNSS doesn't need line of sight as it was needed in previous techniques between its stations. Due to these benefits we are using GNSS technology for structural deformation monitoring. GNSS also has some drawbacks like the positioning accuracy is dependent up on number of available satellites, geometry of satellites, multipath and receiver noise. Un-affordable price of precise GNSS receivers also makes it tougher.

Fusing and organizing many different ideas, opinions, and interpretations into a coherent and acceptable plan or project evaluation is challenging. This is especially true when seeking contributions from a large number of participants, especially when not all can participate in group discussions, or when some prefer to contribute their perspectives anonymously. One of the major breakthroughs in the area of evaluation and program planning has been the use of graphical tools to represent the brainstorming process. This provides a quantitative framework for organizing ideas and general concepts into simple-to-interpret graphs. We developed a new, open-source concept mapping software called R-CMap, which is implemented in R.

Additionally, R-CMap is capable of generating detailed reports that contain useful statistical summaries of the data. The plots and reports can be embedded in Microsoft Office tools such as Word and PowerPoint, where users may manually adjust various plot and table features to achieve the best visual results in their presentations and official reports. The graphical user interface of R-CMap allows users to define cluster names, `change the number of clusters, select rating variables for relevant plots, and importantly, select subsets of respondents by demographic criteria. The latter is particularly useful to project managers in order to identify different patterns of preferences by subpopulations. R-CMap is user-friendly, and does not require any programming experience. However, proficient R users can add to its functionality by directly accessing built-in functions in R and sharing new features with the concept mapping community. (C) 2016 Elsevier Ltd.

+1749,InProceedings,RECREIO: Floss as SAAS for Sharing of Educational Resources,"The objective of this study was to verify if a development model of Units of Learning (UoLs), supported by UoLs authoring tools, that meet the usability criteria and abstract advanced knowledge in programming language by the developers, effectively provides the use and implementation of such resources by teachers in all areas of high school (in this first phase of the research) with few skills with technology. This is also due to the fact that many teachers consume much more resources and also the difficulties faced by teachers and developers in reusing their resources in other environments because they were initially designed for a specific environment. The method was based on the paradigm of Design Science Research (DSR), which allowed us to understand the problem and solve it creatively from useful artifacts. The three cycles of the research used questionnaires, interviews and documentary collection as instruments of data collection of the first cycle of survey and survey of the problem under study, while the non-participant observation and questionnaires were used in the second and third cycles at the time of evaluations of the system interfaces by users. Suggestions for improvements were implemented in the Recreio, while integrations to the Learning Management Systems (LMS) are being developed. Preliminary results showed the importance of Recreio incorporate tools of authorship of UoLs, preferably, free and online. In addition, users' reports made explicit the need for a space for sharing and dissemination of the resources developed directly in LMS, as well as another space destined for exchanging experiences and learning with courses among users.",NA

Therefore, an electronic climate and river level recorder (RCNR) has been built using Open Source Software and Hardware and Mobile Phone. Due to the use of this technology, the RCNR is characterized by being modern, versatile and low cost. The device monitors climatic variables such as air temperature, precipitation and atmospheric pressure. It can be installed in multiple environments such as rivers, streams and canals; where it is possible to monitor such climatic variables, measure river levels or program it as an Early Warning System (EWS), thus contributing to reduce human and material losses in the face of natural disasters.

+1752,Article,Reproducibility and Practical Adoption of GEOBIA with Open-Source Software in Docker Containers,"Geographic Object-Based Image Analysis (GEOBIA) mostly uses proprietary software, but the interest in Free and Open-Source Software (FOSS) for GEOBIA is growing. This interest stems not only from cost savings, but also from benefits concerning reproducibility and collaboration. Technical challenges hamper practical reproducibility, especially when multiple software packages are required to conduct an analysis. In this study, we use containerization to package a GEOBIA workflow in a well-defined FOSS environment. We explore the approach using two software stacks to perform an exemplary analysis detecting destruction of buildings in bi-temporal images of a conflict area. The analysis combines feature extraction techniques with segmentation and object-based analysis to detect changes using automatically-defined local reference values and to distinguish disappeared buildings from non-target structures. The resulting workflow is published as FOSS comprising both the model and data in a ready to use Docker image and a user interface for interaction with the containerized workflow. The presented solution advances GEOBIA in the following aspects: higher transparency of methodology; easier reuse and adaption of workflows; better transferability between operating systems; complete description of the software environment; and easy application of workflows by image analysis experts and non-experts. As a result, it promotes not only the reproducibility of GEOBIA, but also its practical adoption.",10.3390/rs9030290

However, this task is far from trivial, since such projects are sometimes not easy to understand and adapt to target systems, whereas at the same time the reusable assets are not obvious to identify. In this study, we assess open source software projects, with respect to their reusability, i.e., the easiness to adapt them in a new system. By taking into account that domain-specific reuse is more beneficial than domain-agnostic; we focus this study on identifying the application domains that contain the most reusable software projects. To achieve this goal, we compared the reusability of approximately 600 OSS projects from ten application domains through a case study. The results of the study suggested that in every aspect of reusability, there are different dominant application domains. However, Science and Engineering Applications and Software Development Tools, have proven to be the ones that are the most reuse-friendly. Based on this observation, we suggest software engineers, who are focusing on the specific application domains, to consider reusing assets from open source software projects. (C) 2017 Elsevier Inc.

+1755,Article,"SCT: Spinal Cord Toolbox, an open-source software for processing spinal cord MRI data","For the past 25 years, the field of neuroimaging has witnessed the development of several software packages for processing multi-parametric magnetic resonance imaging (mpMRI) to study the brain. These software packages are now routinely used by researchers and clinicians, and have contributed to important breakthroughs for the understanding of brain anatomy and function. However, no software package exists to process mpMRI data of the spinal cord. Despite the numerous clinical needs for such advanced mpMRI protocols (multiple sclerosis, spinal cord injury, cervical spondylotic myelopathy, etc.), researchers have been developing specific tools that, while necessary, do not provide an integrative framework that is compatible with most usages and that is capable of reaching the community at large. This hinders cross-validation and the possibility to perform multi-center studies. In this study we introduce the Spinal Cord Toolbox (SCT), a comprehensive software dedicated to the processing of spinal cord MRI data. SCT builds on previously-validated methods and includes state-of-the-art MM templates and atlases of the spinal cord, algorithms to segment and register new data to the templates, and motion correction methods for diffusion and functional time series. SCT is tailored towards standardization and automation of the processing pipeline, versatility, modularity, and it follows guidelines of software development and distribution. Preliminary applications of SCT cover a variety of studies, from cross-sectional area measures in large databases of patients, to the precise quantification of mpMRI metrics in specific spinal pathways. We anticipate that SCT will bring together the spinal cord neuroimaging community by establishing standard templates and analysis procedures.",10.1016/j.neuroimage.2016.10.009

A case is like a story, related to a real world situation that sources a number of challenging problems, which have no obvious solutions. There have been various applications of CBL in the fields of Medicine, Law, and Business. However, there are a limited number of evidences related to the application of CBL in the field of Software Engineering (SE). In this paper, we present an open source web application called SEABED (Software Engineering Case-Based Learning Database). The feature set supported by SEABED comprises Case Submission, Case Collection, Case Search, Case Review, and Case Evolution. SEABED aims to develop and evolve a rich repository of SE cases that might become a basis for enabling the students, instructors, practitioners, and experts to enhance their SE knowledge in an effective way. Further, we present our approach to build a vibrant SE case-based learning community that triggers enough activity around SEABED, required for the platform to reach a critical and wider mass. We communicated with several SE educators around the world and received positive responses on SEABED. In order to investigate the effectiveness of the CBL methodology followed by SEABED, we conducted an experimental study at an Institute of National Importance in India.

+1762,Article,Specvis: Free and open-source software for visual field examination,"Visual field impairment affects more than 100 million people globally. However, due to the lack of the access to appropriate ophthalmic healthcare in undeveloped regions as a result of associated costs and expertise this number may be an underestimate. Improved access to affordable diagnostic software designed for visual field examination could slow the progression of diseases, such as glaucoma, allowing for early diagnosis and intervention. We have developed Specvis, a free and open-source application written in Java programming language that can run on any personal computer to meet this requirement (http://www. specvis. pl/). Specvis was tested on glaucomatous, retinitis pigmentosa and stroke patients and the results were compared to results using the Medmont M700 Automated Static Perimeter. The application was also tested for inter-test intrapersonal variability. The results from both validation studies indicated low inter-test intrapersonal variability, and suitable reliability for a fast and simple assessment of visual field impairment. Specvis easily identifies visual field areas of zero sensitivity and allows for evaluation of its levels throughout the visual field. Thus, Specvis is a new, reliable application that can be successfully used for visual field examination and can fill the gap between confrontation and perimetry tests. The main advantages of Specvis over existing methods are its availability (free), affordability (runs on any personal computer), and reliability (comparable to high-cost solutions).",10.1371/journal.pone.0186224
+1763,Article,Stochastic actor-oriented modeling for studying homophily and social influence in OSS projects,"Open Source Software projects are communities in which people ``learn the ropes{''} from each other. The social and technical activities of developers evolve together, and as they link to each other they get organized in a network of changing socio-technical connections. Traces of those activities, or behaviors, are typically visible to all, in project repositories and through communication between them. Thus, in principle it may be possible to study those traces to tell which of the observable socio-technical behaviors of developers in these projects are responsible for the forming of persistent links between them. It may also be possible to tell the extent to which links participate in the spread of potential behavioral influences. Since OSS projects change in both social and technical activity over time, static approaches, that either ignore time or simplify it to a few slices, are frequently inadequate to study these networks. On the other hand, ad-hoc dynamic approaches are often only loosely supported by theory and can yield misleading findings. Here we adapt the stochastic actor-oriented models from social network analysis. These models enable the study of the interplay between behavior, influence and network architecture, for dynamic networks, in a statistically sound way. We apply the stochastic actor-oriented models in case studies of two Apache Software Foundation projects, and study code ownership and developer productivity as behaviors. For those, we find evidence of significant social selection effects (homophily) in both projects, but in different directions. However, we find no evidence for the spread (social influence) of either code ownership or developer productivity behaviors through the networks.",10.1007/s10664-016-9431-y

Especially in the higher education sector, IT is playing a vital role in the advancement of teaching and learning practices. Most of the educational organizations have already adopted smart learning environment by upgrading their infrastructure and with proper capacity building among staff members. But in the education sector, sustainability of technology is always being a challenge. To develop learning materials, many institutions have already started using free and open source software (FOSS) tools. FOSS gives freedom to the developer with the provision of various customization options as per the requirements of the class or subject. Moreover, in the longer run, free and open source software could be considered as the best option in education for e-learning implementation, for sustainability. There are many tools which are available for e-learning resource development. Some of them are available online and some are available as an installer for the various platform. In order to adapt ICT in education, especially in non-IT specialization, the faculty members need the training to learn and implement these tools in their classes. But there are many tools, which are specially designed for educators with basic knowledge of computers. Educators can plan their sessions, based on content, duration as well as the level of the subject and the students.

Since then countless libraries across the United States have used the program to create online tutorials in order to teach a variety of information literacy skills including how to search databases, how to evaluate websites, how to create better searches, and how to search for medical information. The Guide on the Side was created by a group of University of Arizona librarians in order to replicate the hands-on experience students received when they attended a library session on how to use a research database. Librarians aimed to give students the guided instruction they received in face-to-face sessions. Sophisticated research databases are often difficult for undergraduate students to use, and they need both background knowledge and repeated practice to use a database successfully. With the Guide on the Side, students are presented with authentic tasks and are able to conduct ``live{''} searches as they are guided through the database. Through these activities, they learn how to locate the information they need quickly. Although a valuable and easy to use software program, instructors and librarians are often at a loss for how to create tutorials that are appealing to students and that are aligned with best practices for online instruction. This paper will focus on best practices when using the Guide on the Side. These best practices have been developed by the author and are based on current educational research focused on online instruction and on usability studies conducted using the Guide on the Side.

To investigate how automated testing is performed in practice, we attempted a thorough, large-scale analysis of open source repositories. Alongside this analysis, we propose a novel approach to reuse such existing tests within projects that lack test code, hence leveraging the quality of such projects with minimal developer intervention. While such an analysis seems to be a straightforward task, we report on various practical challenges that hindered applying our proposed approach for tests' reuse.

In addition, it is very important to understand the inorganic systems that explain the behaviour of atoms, ions and molecules in understanding the phenomena of organic chemistry {[}2]. Therefore, the understanding of spatial structures is central to the discipline of chemistry. However, in textbooks molecular structures are represented as two-dimensional objects and as result, students might find difficult to switch from 2D to 3D structures or images. Using 3 dimensional models help students acquire a better understanding of molecular geometry and encourage active learning.

Firstly, to use the Jmol visualization application as a teaching tool for classroom demonstration. Then, to provide students with the skills to use the molecular visualization tool for their own learning process. Finally, to actively engage students with generation and manipulation of molecular models. Jmol application was used during Lectures to teach about molecular structure. Students then had to download and use the application on their own to complete several worksheets. Later on, Jmol molecular models were also used to aid student understanding of organic chemistry, including isomerism.

Researchers have invested considerable effort in the study of core and peripheral FLOSS developers. To this point, one critical subset of developers that have not been studied are One-Time code Contributors (OTC) - those that have had exactly one patch accepted. To understand why OTCs have not contributed another patch and provide guidance to FLOSS projects on retaining OTCs, this study seeks to understand the impressions, motivations, and barriers experienced by OTCs. We conducted an online survey of OTCs from 23 popular FLOSS projects. Based on the 184 responses received, we observed that OTCs generally have positive impressions of their FLOSS project and are driven by a variety of motivations. Most OTCs primarily made contributions to fix bugs that impeded their work and did not plan on becoming long term contributors. Furthermore, OTCs encounter a number of barriers that prevent them from continuing to contribute to the project. Based on our findings, there are some concrete actions FLOSS projects can take to increase the chances of converting OTCs into long-term contributors.",10.1109/ICSE.2017.25

However, sometimes students are demotivated to contribute due to entrance barriers. On the other hand, gamification is widely used to engage and motivate people to accomplish tasks and improve their performance. The goal of this work is to analyze the use of gamification to orient and motivate undergraduate students to overcome onboarding barriers and engage to OSS projects. To achieve this goal, we implemented four gaming elements (Quests, Points, Ranking, and Levels) in GitLab and assessed the environment by means of a study conducted with 17 students, within a real OSS project (JabRef). At the end of the study, the students evaluated their experience through a questionnaire. We found that the Quest element helped to guide participants and keep them motivated and points helped by providing feedback on students' performed tasks. We conclude that the gamified environment oriented the students in an attempt to make a contribution and that gamification can motivate and orient newcomers' to engage to OSS projects.",10.1109/CHASE.2017.7

+1788,Article,What makes a good contributor? Understanding contributor behavior within large Free/Open Source Software projects - A socialization perspective,"Attracting new contributors is a necessary but not a sufficient condition, to ensure the survival and long-term success of Free/Open Source Software (FOSS) projects. The well-being of a FOSS project depends on the turning of project newcomers into `good contributors' that is to say into individuals that substantially contribute to the project - but also that perform citizenship behaviors that protect and nurture its community. This study is a mixed: methods investigation of the socialization factors that influence contributor performance in large FOSS projects. A qualitative research component resulted into the development of a FOSS socialization framework as well as into the identification of key FOSS project citizenship behaviors. A conceptual model was then developed and empirically examined with 367 contributors from 12 large FOSS projects. The model hypothesizes the mediating effect of two proximal socialization variables, social identification and social integration, between FOSS newcomer socialization factors and contributor performance (conceptualized as task performance and community citizenship behaviors). The results demonstrate the influence of social identification and social integration in predicting contributor performance, as well as the importance of key socialization factors that are: task segregation, task purposefulness, interaction intensity, and supportiveness. Theoretical and practical implications are discussed. (C) 2017 Elsevier B.V. All rights reserved.",10.1016/j.jsis.2017.03.001
+1790,InProceedings,Which Review Feedback Did Long-Term Contributors Get on OSS Projects?,"Open Source Software (OSS) cannot exist without contributions from the community. In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process.

+1792,Article,"{OSS} popularity: {Understanding} the relationship between user-developer interaction, market potential and development stage","Following the growing interest and concerns regarding the open source software (OSS) phenomenon among academics and practitioners, many studies have been conducted to understand the factors that influence OSS success. However, research has primarily explored such factors in the context of well-known projects, such as Linux and Apache. Yet, lesser-known projects must be examined to gain a more complete understanding. Accordingly, this paper focuses on lesser-known projects to examine three factors that influence OSS popularity: user-developer interaction, market potential and development stage. Specifically, we develop an empirical model of OSS popularity and test our hypotheses on data from 657 open source projects. The findings show that the combination of the three factors has a positive effect on OSS popularity. Moreover, in contrast to previous research, the results reveal that exchanges among users and developers have a stronger influence on OSS popularity than bug-related activities. Overall, this research provides a novel way to measure OSS popularity for lesser-known projects and offers organizations a better understanding of OSS.Alternate abstract:Alors que le logiciel libre a particulierement retenu l'attention et Pintérét du monde académique et managérial, beaucoup de recherches ont cherché á comprendre les facteurs de succes de ces logiciels OSS.

AgHA was synthesized by a chemical precipitation method. After characterization, AgHA was mixed with Bio-Oss((R)) at three ratios: 1:1, 1:2, and 1:4 by weight. Then, Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were used to test the antibacterial activity of the mixture. Human periodontal ligament fibroblasts and rat bone marrow stromal cells were selected for cytocompatibility experiments. According to results, the peak value of the size of the AgHA was concentrated in the 100-200 nm range, and AgHA particles consisted of short rods. It was confirmed that the structure of AgHA was similar to that of standard hydroxyapatite. All three mixture ratios exhibited obvious antimicrobial properties, which increased with increasing AgHA. According to the effects on the expression of bacterial virulence genes, groups 1:1 and 1:2 both negatively affected Pg and Fn more significantly than group 1:4. Cytotoxicity experiments showed that 1:1 caused little cytotoxicity, while groups 1:2 and 1:4 exerted no significant cytotoxicity. Considering its biological compatibility and antibacterial activity, group 1:2 is the most recommended. (c) 2017 Wiley Periodicals, Inc.

+1795,Article,A 3-Dimensional Approach for Analysis in Orthognathic Surgery-Using Free Software for Voxel-Based Alignment and Semiautomatic Measurement,"Purpose: In orthognathic surgery, the repeatability of 3-dimensional (3D) measurements is limited by the need for manual reidentification of reference points, which can incorporate errors greater than 1 mm for every 4 repeated measurements. This report describes a semiautomatic approach to decrease the manual reidentification error. This study evaluated the repeatability of surgical outcome measurements using the semiautomatic approach. Furthermore, a step-by-step guide is provided to enable researchers and clinicians to perform the 3D analysis by themselves. Materials and Methods: Evaluating surgical outcome consists of 2 parts. First, the scans are aligned at the anterior cranial base. Second, a semiautomatic approach is used to place 3 dental reference points at exactly the same sites of the pre-and postoperative maxilla. Because the maxilla is repositioned during surgery but otherwise unaltered, the reference points should be identical if the pre-and postoperative scans are aligned at the maxilla. Therefore, the authors propose the insertion of reference points on the preoperative scan and then repositioning a copy of the preoperative reference points relative to the postoperative scan. To align the reference points on the postoperative scan, the hard palate is used as a mutual maxillary reference structure. A reproducibility test was performed in 10 participants by analyzing the difference between repeated measurements. Results: Repeated linear measurements differed by less than 0.1 mm along all 3 axes (standard deviations, < 0.1 mm). The 2 largest differences between repeated measurements were 0.33 mm along the superoinferior axis and 0.29 along the anteroposterior axis. Repeated rotational measurements differed by less than 0.1 degrees around all 3 axes (standard deviations, <= 0.1 degrees). Conclusion: The semiautomatic approach showed excellent linear and angular repeatability. The algorithm can be implemented in the clinical evaluation of orthognathic surgical outcome and postoperative relapse.

The topic of bugs has been extensively investigated and reported in the literature. Unfortunately, the existential question of all ``whether a reported bug will be fixed or not{''} has not received much attention. The paper presents an empirical study on four open source projects to examine the factors that influence the likelihood of a bug getting fixed or not. Overall, our study can be contextualized as a conceptual replication of a previous study on Microsoft systems from a commercial domain. The similarities and differences in terms of the design, execution, and results between the two studies are discussed. It was observed from these systems that the reputations of the reporter and assigned developer to fix it, and the number of comments on a bug have the most substantial impact on its probability to get fixed. Moreover, we formulated a predictive model from features available as soon as a bug is reported to estimate whether it will be fixed or not. Intra and inter (cross) project validations were performed. Precision and Recall metrics were used to assess the predictive model.

Such capstone projects may be student-designed, instructor-designed, designed in conjunction with outside companies, or integrated with ongoing free and open source (FOSS) projects. The literature shows that the FOSS approach has attracted a great deal of interest, in particular when implemented with projects that have humanitarian goals (HFOSS). In this article, we describe five unique models from five distinct types of institutions for incorporating sustained FOSS or HFOSS (alternatively H/FOSS) project work into capstone experiences or courses. The goal is to provide instructors wishing to integrate open source experiences into their curriculum with additional perspectives and resources to help in adapting this approach to the specific needs and goals of their institution and students. All of the models presented are based on sustained engagement with H/FOSS projects that last at least one semester and often more. Each model is described in terms of its characteristics and how it fits the needs of the institution using the model. Assessment of each model is also presented. We then discuss the themes that are common across the models, such as project selection, team formation, mentoring, and student assessment. We examine the choices made by each model, as well as the challenges faced. We end with a discussion how the models have leveraged institutional initiatives and collaborations with outside organizations to address some of the challenges associated with these projects.",10.1145/3145476

Growing urbanization is one of the anthropic causes of UHI. The UHI phenomenon has a negative impact on the life quality of the local population (thermal discomfort, summer thermal shock, etc.), thus investigations and analyses on this topic are really useful and important for correct and sustainable urban planning; this study is included in this context. A multi-temporal analysis was performed in the municipality of Modena (Italy) to identify and estimate the Surface Urban Heat Island (SUHI, strictly correlated to the UHI phenomenon) from 2014 to 2017. For this purpose, Landsat-8 satellite images were processed with Quantum Geographic Information System (QGIS) to obtain the Land Surface Temperature (LST) and the Normalized Difference Vegetation Index (NDVI). For every pixel, LST and NDVI values of three regions of interest (ROI, i.e., Countryside, Suburbs, and City Center) were extracted and their correlations were investigated. A maximum variation of 6.4 degrees C in the LST values between City Center and Countryside was highlighted, confirming the presence of the SUHI phenomenon even in a medium-sized municipality like Modena. The implemented procedure demonstrates that satellite data are suitable for SUHI identification and estimation, therefore it could be a useful tool for public administration for urban planning policies.",10.3390/su10051678
+1803,Article,A Participation Architecture to Support User Peripheral Participation in a Hybrid FOSS Community,"Participation by product users is critical to success in free, open-source software (FOSS) software communities as they originate and develop valuable ideas for product innovation that are unlikely to originate from the core software development community. Users tend to be involved at the periphery of FOSS communities, suggesting new product ideas, highlighting problems with user documentation, or explaining when the product design fails to fit with the needs of their local user application domain. As an increasing number of FOSS projects employ a hybrid participation model that combines volunteer effort with paid software development effort or product support, it can be difficult for non-developer users to participate in product innovation. In colocated organizations, it is theorized that peripheral participants learn how to engage with the practices and cultural identity of a community through a sociocultural apprenticeship known as legitimate peripheral participation. But we have little literature that explores how legitimate peripheral participation is enabled in online communities.The research study presented in this article explores how participation by peripheral users in a hybrid FOSS project is afforded by participation architecture channels and community mechanisms that mediate two forms of engagement: a “cognitive apprenticeship” that introduces participants to situated domain activity, such as the community processes involved in product innovation, and a “social apprenticeship” by which participants become enculturated in the system of meanings, values, norms, and behaviors that govern community/participant identity. We identified five stages of community innovation, analyzing sociotechnical affordances of the online participation architecture that enable peripheral participants to internalize the meanings of community practice and to develop a social identity within the FOSS community. Our contribution to theory is provided by the substantive explanation of the cognitive and social translations that enable legitimate peripheral participation in online communities, mediated by sociotechnical access channels and mechanisms that afford two contrasting forms of opportunities for action: those resulting from interactions between a goal-oriented actor and the technology platform features or channels of participation, and those associated with the social structures, roles, and relationships underpinning community interactions. Neither of these is sufficient without the other. Our contribution to practice is provided by an explanation of how four distinct categories of affordance provide these cognitive and social apprenticeship benefits, allowing participation architecture designers to cater to all forms of peripheral user participation. We conclude that the technical affordances of a typical FOSS community participation architecture are insufficient to mediate peripheral participation by nontechnical users. Meaningful participation is mediated by interactions between boundary spanners who play knowledge-brokering and organizational bridging roles. The combination of technical and social affordances enables peripheral participants to acquire an interior view of community practices and social culture and in turn to introduce new ideas, new values, and new rationales to produce a generative dance of innovation that percolates through the community.",10.1145/3290837

+1809,Article,A Study on the Field Data Applicability of Seismic Data Processing using Open-source Software (Madagascar),"We performed the seismic field data processing using an open-source software (Madagascar) to verify if it is applicable to processing of field data, which has low signal-to-noise ratio and high uncertainties in velocities. The Madagascar, based on Python, is usually supposed to be better in the development of processing technologies due to its capabilities of multidimensional data analysis and reproducibility. However, this open-source software has not been widely used so far for field data processing because of complicated interfaces and data structure system. To verify the effectiveness of the Madagascar software on field data, we applied it to a typical seismic data processing flow including data loading, geometry build-up, F-K filter, predictive deconvolution, velocity analysis, normal moveout correction, stack, and migration. The field data for the test were acquired in Gunsan Basin, Yellow Sea using a streamer consisting of 480 channels and 4 arrays of air-guns. The results at all processing step are compared with those processed with Landmark's ProMAX (SeisSpace R5000) which is a commercial processing software. Madagascar shows relatively high efficiencies in data IO and management as well as reproducibility. Additionally, it shows quick and exact calculations in some automated procedures such as stacking velocity analysis. There were no remarkable differences in the results after applying the signal enhancement flows of both software. For the deeper part of the substructure image, however, the commercial software shows better results than the open-source software. This is simply because the commercial software has various flows for de-multiple and provides interactive processing environments for delicate processing works compared to Madagascar. Considering that many researchers around the world are developing various data processing algorithms for Madagascar, we can expect that the open-source software such as Madagascar can be widely used for commercial-level processing with the strength of expandability, cost effectiveness and reproducibility.",10.7582/GGE.2018.21.3.171

We found that although workers valued the flexibility of working from home, they had difficulty focusing on their work for sustained time periods and often felt isolated. This motivated them to use coworking spaces - physical spaces used as work space by workers not on the same team or even the same firm - as a critical part of their space ecology.

+1817,Article,Agile Acceptance Test-Driven Development of Clinical Decision Support Advisories: Feasibility of Using Open Source Software,"Background: Moving to electronic health records (EHRs) confers substantial benefits but risks unintended consequences. Modern EHRs consist of complex software code with extensive local configurability options, which can introduce defects. Defects in clinical decision support (CDS) tools are surprisingly common. Feasible approaches to prevent and detect defects in EHR configuration, including CDS tools, are needed. In complex software systems, use of test-driven development and automated regression testing promotes reliability. Test-driven development encourages modular, testable design and expanding regression test coverage. Automated regression test suites improve software quality, providing a ``safety net{''} for future software modifications. Each automated acceptance test serves multiple purposes, as requirements (prior to build), acceptance testing (on completion of build), regression testing (once live), and ``living{''} design documentation. Rapid-cycle development or ``agile{''} methods are being successfully applied to CDS development. The agile practice of automated test-driven development is not widely adopted, perhaps because most EHR software code is vendor-developed. However, key CDS advisory configuration design decisions and rules stored in the EHR may prove amenable to automated testing as ``executable requirements.{''} Objective: We aimed to establish feasibility of acceptance test-driven development of clinical decision support advisories in a commonly used EHR, using an open source automated acceptance testing framework (FitNesse). Methods: Acceptance tests were initially constructed as spreadsheet tables to facilitate clinical review. Each table specified one aspect of the CDS advisory's expected behavior. Table contents were then imported into a test suite in FitNesse, which queried the EHR database to automate testing. Tests and corresponding CDS configuration were migrated together from the development environment to production, with tests becoming part of the production regression test suite. Results: We used test-driven development to construct a new CDS tool advising Emergency Department nurses to perform a swallowing assessment prior to administering oral medication to a patient with suspected stroke. Test tables specified desired behavior for (1) applicable clinical settings, (2) triggering action, (3) rule logic, (4) user interface, and (5) system actions in response to user input. Automated test suite results for the ``executable requirements{''} are shown prior to building the CDS alert, during build, and after successful build. Conclusions: Automated acceptance test-driven development and continuous regression testing of CDS configuration in a commercial EHR proves feasible with open source software. Automated test-driven development offers one potential contribution to achieving high-reliability EHR configuration. Vetting acceptance tests with clinicians elicits their input on crucial configuration details early during initial CDS design and iteratively during rapid-cycle optimization.",10.2196/medinform.9679

In this paper, we investigate how and why quasi-contributors (external developers who did not succeed in getting their contributions accepted to an OSS project) fail. To achieve our goal. we collected data from 21 popular, non-trivial GitHub projects, identified quasi-contributors, and analyzed their pull-requests. In addition, we conducted surveys with quasi-contributors, and project's integrators, to understand their perceptions about nonacceptance. We found 10,099 quasi-contributors about 70\\% of the total actual contributors that submitted 12,367 nonaccepted pull-requests. In five projects, we found more quasi-contributors than actual contributors. About one-third of the developers who took our survey disagreed with the nonacceptance, and around 30\\% declared the nonacceptance demotivated or prevented them from placing another pull-request. The main reasons for pull-request nonacceptance from the quasicontributors' perspective were ``superseded/duplicated pull-request{''} and ``mismatch between developer's and team's vision/opinion{''} A manual analysis of a representative sample of 263 pull-requests corroborated with this finding.

With today's increasingly important and complex OSS, lacking software security knowledge to handle security vulnerabilities in OSS development will result in more breaches that are serious in the future. Learning software security is a difficult and challenging task since the domain is quite context specific and the real project situation is necessary to apply the security concepts within the specific system. Many OSS proponents believe that the OSS community offers significant learning opportunities from its best practices. However, studies that specifically explore security knowledge sharing and learning in OSS communities are scarce. This research is intended to fill this gap by empirically investigating factors that affect knowledge sharing and learning about software security and the relationship among them. A conceptual model is proposed that helps to conceptualize the linkage between socio-technical practices and software security learning processes in OSS communities. A questionnaire and statistical analytical techniques were employed to test hypothesized relationships in the model to gain a better understanding of this research topic.",10.3390/computers7040049

This is at odds with current practice of performance testing, which predominantely focuses on long-running tests against entire systems in production-like environments. Alternatively, software microbenchmarking attempts to establish a performance baseline for small code fragments in short time. This paper investigates the quality of microbenchmark suites with a focus on suitability to deliver quick performance feedback and CI integration. We study ten open-source libraries written in Java and Go with benchmark suite sizes ranging from 16 to 983 tests, and runtimes between 11 minutes and 8.75 hours. We show that our study subjects include benchmarks with result variability of 50\\% or higher, indicating that not all benchmarks are useful for reliable discovery of slow-downs. We further artificially inject actual slowdowns into public API methods of the study subjects and test whether test suites are able to discover them. We introduce a performance-test quality metric called the API benchmarking score (ABS). ABS represents a benchmark suite's ability to find slowdowns among a set of defined core API methods. Resulting benchmarking scores (i.e., fraction of discovered slowdowns) vary between 10\\% and 100\\% for the study subjects. This paper's methodology and results can be used to (1) assess the quality of existing microbenchmark suites, (2) select a set of tests to be run as part of CI, and (3) suggest or generate benchmarks for currently untested parts of an API.",10.1145/3196398.3196407

As a result, system and software engineers require efficient methods to track defect identification and removal efforts during the software development lifecycle. To support such activities, we have developed a free and open source version of the SoftWare Error Estimation Program (SWEEP), named SweET (Software Defect Estimation Tool), which has not been publicly available to the software engineering community for several years. SWEEP's four modes have been simplified and combined into three modes namely, (i) time-based, (ii) phase-based, and (iii) defect insertion in SweET. Moreover, SweET uses the Weibull model, which is more flexible than the Rayleigh model included in SWEEP. Furthermore, the model fitting performed with least squares estimation in SWEEP has been replaced with an expectation conditional maximization (ECM) algorithm, which is both stable and efficient.",10.1109/RAM.2018.8463122

In this paper, the discrete modeling framework has been proposed to study the reliability growth process of OSS systems with multiple releases. The proposed model is based upon the assumption that during up-gradation some new faults are introduced in the code in addition to the left over fault content of the previous version. To validate our model, we have chosen two successful open source projects-Mozilla and Apache for its multi release failure datasets. Graphs representing goodness of fit of the proposed model have been drawn. The parameter estimates and measures of goodness of fit criteria suggest that the proposed software reliability growth model for multi-release OSS fits the actual datasets very well. An optimal release policy has been formulated by taking into account the cost of fault removal during testing and operational phases and reliability targets pre-specified by the decision makers. In addition, numerical example along with the sensitivity analysis has been provided to illustrate optimal release policy.",10.1142/S0219877018500116

The use of Business Intelligence (BI) tools can contribute to the improvement of the organizational processes of these organizations. However, the high financial cost, in many cases, makes it impossible for public institutions to acquire proprietary BI solutions. An alternative is the use of solutions based on free and/or open source software. To identify, among the available OSS-based BI tools, which is the most appropriate for implementation in public bodies, it is necessary to apply some specific model for evaluation and selection. The literature describes several generic methods for assessing and comparing OSS. In this work, we select a suitable method and derive a model for the comparison and selection of OSS-based BI tools able to meet the demands of public organizations. In addition, through a case study, we demonstrate how this model can be used in the selection of a tool that can contribute to the improvement of information management in an organizational environment.",10.1145/3229345.3229359

SMEs aim to become more efficient and competitive, but often experience challenges. Open Source Software (OSS) is considered to yield key benefits for SMEs because it is free to access, distribute and customise, peer-reviewed for reliability. However, certain drawbacks can hinder SMEs from adopting OSS such as uncertain support, need for technical skill for usage, incomplete functionality to mention a few. The broadband initiative in the Western Cape looked to enable the access of OSS online through the provision of broadband internet for organisations including SMEs. This research was aimed, through a qualitative analysis, mainly at examining the attitude of SMEs toward OSS by analysing the benefits as well as the drawbacks of using OSS. The research also analysed the effect of the broadband initiative on the attitude of SMEs toward OSS uptake. Additionally, the roles that intermediaries undertake in OSS communities for promoting the uptake of OSS in SMEs, which were investigated were decentralised school, bridging school, arterial school, communities of practice and ecosystems school. These intermediary roles were analysed to find out which role would be most significant for facilitating OSS uptake.",NA

Material and MethodsSurfaces of a novel particulate bovine bone graft, Moa-Bone((R)) were compared with Bio-Oss((R)) using scanning electron microscopy. Six sheep then had maxillary sinus grafting bilaterally, covered with BioGide((R)). Grafted maxillae were harvested after 4, 6 and 12weeks. Healing was described for half of each site using resin-embedded ground sections. For the other half, paraffin-embedded sections were examined using tartrate resistant acid phosphatase staining for osteoclast activity, runt-related transcription factor2 immunohistochemistry for pre-osteoblasts and osteoblasts and proliferating cell nuclear antigen for proliferative cells. ResultsMoa-Bone((R)) had a smoother, more porous fibrous structure with minimal globular particles compared with Bio-Oss((R)). After 4weeks, woven bone formed on both grafts and the Moa-Bone((R)) particles also showed signs of resorption. After 12weeks, Moa-Bone((R)) continued to be resorbed, however Bio-Oss((R)) did not; both grafts were surrounded by maturing lamellar bone. Moa-Bone((R)) was associated with earlier evidence of runt-related transcription factor 2-positive cells. Moa-Bone((R)) but not Bio-Oss((R)) was associated with strong tartrate resistant acid phosphatase-positive osteoclasts on the graft surface within resorption lacunae at both 4 and 6weeks post-grafting. ConclusionBoth materials supported osseous healing and maturation without inflammation. Moa-Bone((R)) showed marked osteoclast activity after 4 and 6weeks and demonstrated positive attributes for grafting, if complete remodeling of the graft within the site is desired. Further optimization of Moa-Bone((R)) for maxillofacial applications is warranted.",10.1111/jre.12490

The gains obtained from the reuse of community-developed libraries may be offset by the cost of detecting, assessing, and mitigating their vulnerabilities in a timely manner. In this paper we present a novel method to detect, assess and mitigate OSS vulnerabilities that improves on state-of-the-art approaches, which commonly depend on metadata to identify vulnerable OSS dependencies. Our solution instead is code-centric and combines static and dynamic analysis to determine the reachability of the vulnerable portion of libraries used (directly or transitively) by an application. Taking this usage into account, our approach then supports developers in choosing among the existing non-vulnerable library versions. Vulas, the tool implementing our code-centric and usage-based approach, is officially recommended by SAP to scan its Java software, and has been successfully used to perform more than 250000 scans of about 500 applications since December 2016.

The metadata about a change includes a change message to record the intention of the change. Classification of changes, based on change messages, into different change types has been explored in the past to understand the evolution of software systems from the perspective of change size and change density only. However, software evolution analysis based on change classification with a focus on change evolution patterns is still an open research problem. This study examines change messages of 106 OSS projects, as recorded in the git repository, to explore their evolutionary patterns with respect to the types of changes performed over time. An automated keyword-based classifier technique is applied to the change messages to categorize the changes into various types (corrective, adaptive, perfective, preventive, and enhancement). Cluster analysis helps to uncover distinct change patterns that each change type follows. We identify three categories of 106 projects for each change type: high activity, moderate activity, and low activity. Evolutionary behavior is different for projects of different categories. The projects with high and moderate activity receive maximum changes during 76-81 months of the project lifetime. The project attributes such as the number of committers, number of files changed, and total number of commits seem to contribute the most to the change activity of the projects. The statistical findings show that the change activity of a project is related to the number of contributors, amount of work done, and total commits of the projects irrespective of the change type. Further, we explored languages and domains of projects to correlate change types with domains and languages of the projects. The statistical analysis indicates that there is no significant and strong relation of change types with domains and languages of the 106 projects.",10.1007/s11704-016-6301-0

Only a few empirical studies investigate how the choice of components is conducted in industrial practice. This is important to understand to tailor research solutions to the needs of the industry. Existing studies focus on the choice for off-the-shelf (OTS) components. It is, however, also important to understand the implications of the choice of alternative component sourcing options (CSOs), such as outsourcing versus the use of OTS. Previous research has shown that the choice has major implications on the development process as well as on the ability to evolve the system. The objective of this study is to explore how decision making took place in industry to choose among CSOs. Overall, 22 industrial cases have been studied through a case survey. The results show that the solutions specifically for CSO decisions are deterministic and based on optimization approaches.

Although social networks constructed in online environment can reduce such possibilities, it is not without limitations. One possible mechanism for learning and knowledge flow is direct watching and observation. This study investigates the impact of co-membership taking into account the alternative mechanism of watching under the setting of OSS development at GitHub. It finds that both co-membership and watching contribute positively to OSS success, and thus shows the co-existence of both experiential learning and vicarious learning for OSS development.

Companies get involved in FLOSS projects to acquire user innovations [3, 12], to reduce costs [8, 11], to make money on complementary services [13], etc. Such intense involvement may change the nature of FLOSS development and pose critical challenges for the sustainability of the projects. For example, it has been found that a company's full control and intense involvement is associated with a decrease of volunteer inflow [13]. Sometimes a project may fail after one company pulls resources from the project [13]. This raises concerns about the domination of one company in a project. In large projects like OpenStack, there are often hundreds of companies involved in contributing code. Despite substantial researches on commercial participation, whether or not one company dominates a project and the impact of such domination has never been explicitly explored. We investigate four main projects of OpenStack, a large ecosystem that has had a tremendous impact on computing and society, to answer the following research questions: Does one company dominate the project's development (RQ1)?

Our major assumption is that a number of automotive vehicles run around the world in the near future and their sensors and program modules are available for other purposes. In our experiments, we confirmed that hidden area can be visualized by using such data and modules.",10.1109/ISMAR-Adjunct.2018.00103
+1863,InProceedings,Do Review Feedbacks Influence to a Contributor's Time Spent on OSS Projects?,"Open Source Software (OSS) does not work without contributions from the community. In particular, long-term contributors (LTCs) (e.g., committer), defined as contributors who spend at least one year on OSS projects, play a crucial role in a project success because they would have permission to add (commit) code changes to a project's version control system, and to become a mentor for a beginner in OSS projects. However, contributors often leave a project before becoming a LTC because most contributors are volunteers. If contributors are motivated in their work in OSS projects, they might not leave the projects. In this study, we examine the phenomena involved in becoming a LTC in terms of motivation to continue in OSS projects. In particular, our target motivation is to understand what is involved in long-term contribution with other expert contributors. We study classifier to identify a LTC who will contribute patch submissions for more than one year based on collaboration in terms of the code review process. In detail, we analyze what review feedbacks encourage a contributor to continue with OSS project. Using a Qt project dataset, we build a prediction model to identify a LTC. We find that not only contributor's activities, but also a reviewer feedbacks, useful in identifying LTCs.",10.1109/BCD2018.2018.00028

METHODS: We demonstrate a novel technique to overcome these challenges, namely the creation of stable innominate artery access by inserting a through-and-through body floss wire from the right brachial artery to the femoral artery. RESULTS: We successfully performed right carotid artery stenting in 3 patients with Type III arch anatomy. All patients received regular outpatient follow-up uneventfully for more than 1 year. CONCLUSIONS: This facilitates the procedure of the right carotid artery stenting in patients with Type III aortic arch.",10.1093/icvts/ivx273
+1866,Article,Evaluation of Guided Bone Regeneration Using the Bone Substitute Bio-Oss® and a Collagen Membrane in a Rat Cranial Bone Defect Model,"The value of using the xenogeneic bone substitute Bio-Oss (R) and a collagen membrane for guided bone regeneration (GBR) was evaluated. Five-millimeter bone defects were created in the cranial bones of 15, 15-week-old, male Sprague-Dawley rats, five of which were left unfilled (Group A), five were filled with Bio-Oss (R) (Group B), and five were filled with Bio-Oss (R) and a collagen membrane (Group C). They were evaluated by micro-computed tomography (micro-CT) Weeks 8 after bone defect creation. The animals were euthanized in Week 8, and tissue samples were taken. The sampled tissue was evaluated by the Kawamoto technique for preparing nondecalcified frozen sections. On micro-CT, radiopacities in the bone defects were evident in Groups B and C, but not in Group A. The amount of radiopacity tended to be greater in Group C than in Group B. Histologically, no new bone formation was observed in Group A. In Groups B and C, new bone formation around the Bio-Oss (R) was apparent and some osteoblastic cells were observed along the new bone. The Bio-Oss (R) was not absorbed up to Week 8, suggesting that it may be a potential bone regeneration scaffold. The combined use of a collagen membrane anchored the Bio-Oss (R) in close contact with the cranial bone, suggesting that it may help create a favorable environment for bone formation. The combination of Bio-Oss (R) and a collagen membrane in GBR may be useful for bone defect regeneration.",10.2485/jhtb.27.79

Although the OSS evaluation process and the information it requires are nowadays well known, users still have problems finding the right information and are not supported by any decision support system. Objective: The aim of this study is to bridge the gap between OSS adoption models, especially with the aim of supporting users in evaluating the OSS they are planning to select. Method: To reach this aim, we studied the processes and the information considered by the major OSS assessment models. Then we carried out a case study to identify which information can be automatically retrieved from the main OSS platforms, namely GitHub, SonarCloud, and StackExchange. Finally, we characterized the maturity of the projects available on these three platforms. Results: Projects available on the three platforms are commonly old, stable, and mature ones. Moreover, thanks to the API provided, we were able to extract most of the information not commonly accessible from the main website. Conclusions: Our results confirm that it is possible to develop a decision support system based on these three platforms, and that is also possible to evaluate both the quality and the maturity of the projects available there.",10.1016/j.infsof.2018.07.009

A systematic mapping study (SMS) performed in 2013 structured the research area on the use of FLOSS projects in SEE. Objective: Update the 2013 SMS with studies published in the last five years, classifying and summarizing them to discuss trends and identify research gaps in the context of the use of FLOSS projects in SEE. Method: We retrieved and analyzed a set of 4132 papers published from 2013 to 2017, from which 33 papers were selected and classified. We analyzed the new results and compared them with those from the previous SMS to confirm or discover trends. Results: The updated mapping summarizes the studies published in the last five years, most of them in conferences. Our analysis confirmed trends previously observed for three facets (SE area, curriculum choice and assessment type) and discovered new trends for other facets. Conclusion: Studies report the use of FLOSS projects in regular, comprehensive SE courses. The prevalence of experience reports over solution proposals in the last five years may indicate that researchers are more concerned with the use and evaluation of existing proposals, although there are still opportunities for more empirical work based on sound educational research methods.",10.1145/3266237.3266249

For a wide range of flight conditions and mission task elements, the test pilot feedback is the essential measure upon which the design choices are made. Thus, it is becoming of fundamental importance to be able to simulate a representative model of the vehicle in a pilot-in-the loop environment as early as possible in the design stage.

+1872,Article,Facilitating the analysis of the multifocal electroretinogram using the free software environment R,"Purpose: The large amount of data rendered by the multifocal electroretinogram (mfERG) can be analyzed and visualized in various ways. The evaluation and comparison of more than one examination is time-consuming and prone to create errors. Using the free software environment R we developed a solution to average the data of multiple examinations and to allow a comparison of different patient groups. Methods: Data of single mfERG recordings as exported in .csv format from a RETIport 21 system (version 7/03, Roland Consult) or manually compiled .csv files are the basis for the calculations. The R software extracts response densities and implicit times of N1 and P1 for the sum response, each ring eccentricity, and each single hexagon. Averages can be calculated for as many subjects as needed. The mentioned parameters can then be compared to another group of patients or healthy subjects. Application of the software is illustrated by comparing 11 patients with chloroquine maculopathy to a control group of 7 healthy subjects. Results: The software scripts display response density and implicit time 3D plots of each examination as well as of the group averages. Differences of the group averages are presented as 3D and grayscale 2D plots. Both groups are compared using the t-test with Bonferroni correction. The group comparison is furthermore illustrated by the average waveforms and by boxplots of each eccentricity. Conclusions: This software solution on the basis of the programming language R facilitates the clinical and scientific use of the mfERG and aids in interpretation and analysis.",10.5301/ejo.5001018
+1873,Article,Fluxpart: Open source software for partitioning carbon dioxide and water vapor fluxes,"The eddy covariance method is regularly used for measuring gas fluxes over agricultural fields and natural ecosystems. For many applications, it is desirable to partition the measured fluxes into constitutive components: the water vapor flux into transpiration and direct evaporation components, and the carbon dioxide flux into photosynthesis and respiration components. The flux variance similarity (FVS) partitioning method is based on flux variance similarity relationships and correlation analyses of high-frequency eddy covariance data (Scanlon and Sahu, 2008; Scanlon and Kustas, 2010, 2012). The FVS method is relatively complex computationally, and that complexity has likely been an impediment to greater use and testing of the procedure. In this work, we present a new algebraic solution to the key computational task in the partitioning algorithm, which significantly simplifies the FVS method. We also introduce Fluxpart, a free and open source Python 3 module that implements the FVS partitioning procedure.

Moreover, society may greatly benefit when software originators choose an open-source development strategy as their products become widely available, readily customizable, and open to community contributions. In this study, we present an economic model to study how software licensing attributes affect a software originator's decisions, aiming to provide policy makers with insights into how welfare-improving, open-source outcomes can be incentivized. We show that when a competing contributor is apt at reaping the benefits of software development investment, a less restrictive open source license (e.g., Berkeley Software Distribution, or BSD style) can improve welfare. On the other hand, when the originator is better at leveraging investment and service costs are high, a more restrictive license (e.g., General Public License, or GPL style) can be best for social welfare even when a contributor can cost-efficiently develop the software.",10.1287/isre.2017.0726

The growing number of connected devices and reported software vulnerabilities increases the importance firmware updates. Maturity models for software security do include parts of this, but are lacking in several aspects. This paper presents and evaluates a maturity model (HAVOSS) for handling vulnerabilities in third party OSS and COTS components. The maturity model was designed by first reviewing industry interviews, current best practice guidelines and other maturity models. After that, the practices were refined through industry interviews, resulting in six capability areas covering in total 21 practices. These were then evaluated based on their importance according to industry experts. It is shown that the practices are seen as highly important, indicating that the model can be seen as a valuable tool when assessing strengths and weaknesses in an organization's ability to handle firmware updates.",10.1007/978-3-030-03673-7\\_6
+1883,Article,Heteroatom-doped porous carbons derived from moxa floss of different storage years for supercapacitors,"Two novel carbons (MCs) derived from moxa floss of different storage years have been prepared by two low-cost and facile approaches, which are hydrothermal carbonization at a low temperature (200 degrees C) and direct pyrolysis at a moderate temperature (500 degrees C) followed by potassium hydroxide (KOH) activation strategy at a high temperature (800 degrees C), respectively. The physicochemical properties of MCs are investigated by Raman spectra, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and nitrogen adsorption-desorption isotherms. Results show that MCs derived from moxa floss of different storage years by two facile approaches possess different morphologies: MCs by hydrothermal carbonization (denoted as MC-1, MC-2 and MC-3) exhibit porous nanosheet structures, the highest specific surface area is about 1788.6 m(2) g(-1), and the largest total pore volumes is around 0.8170 cm(3) g(-1), while MCs by direct pyrolysis (denoted as MC-4, MC-5 and MC-6) have basically blocky and rod-like morphologies, the highest specific surface area is about 1628.0 m(2) g(-1), and the largest total pore volume is around 0.7058 cm(3) g(-1). However, despite the different morphologies, all MCs possess a similar hierarchical porous structure, numerous heteroatom groups and good electrical conductivity. Therefore, these low-cost, biomass-derived porous carbons with promising capacitive performance are used for supercapacitors application with high performance, for example, the as-assembled supercapacitor based on MC-5 exhibits a high specific capacitance of 288.3 F g(-1) at 0.25 A g(-1), an excellent rate performance of 243.5 F g(-1) even at 30 A g(-1) with 84.5\\% capacitance retention of its initial specific capacitance, and an outstanding long-term cycling stability with 98.7\\% capacitance retention after 10 000 cycles at 5 A g(-1). Furthermore, the maximum energy density for these supercapacitors with an aqueous electrolyte in a two-electrode system is about 10.0 W h kg(-1) at a power density of 70.3 W kg(-1). Therefore, this work opens up a whole new field for the applications of moxa floss and this novel concept of moxa floss use is an extremely promising strategy for developing high-performance carbons with porous structures and heteroatom-doping from renewable sources.",10.1039/c8ra01672k

Communities are commonly defined as a group of people sharing common norms or values. The common interest of an OSS project is obvious: to develop software under an OSS license. When we look at the rather general definition of a community, we see that there is a similarity to the term `organization'. This paper draws parallels between OSS projects and the general elements of an organization and shows the different elements comprised in an OSS community: people, organization and assets. Each of those elements is enriched with examples from different research in the corresponding OSS research stream and provides a broad overview of the elements of OSS projects.

An Empirical Study on Characterizing A Software Maintainability Ontology in Open Source Software,"Beyond the functional requirements of a system, software maintainability is essential for project success. While there exists a large knowledge base of software maintainability, this knowledge is rarely used in open source software due to the large number of developers and inefficiency in identifying quality issues. To effectively utilize the current knowledge base in practice requires a deeper understanding of how problems associated with the different qualities arise and change over time. In this paper, we sample over 6000 real bugs found from several Mozilla products to examine how maintainability is expressed with subgroups of repairability and modifiability. Furthermore, we manually study how these qualities evolve as the products mature, what the root causes of the bugs are for each quality and the impact and dependency of each quality. Our results inform which areas should be focused on to ensure maintainability at different stages of the development and maintenance process.",10.1109/QRS.2018.00036

I contribute to prior work on learning within FLOSS and also to the learning sciences by illustrating how FLOSS supports lifelong learning and working by providing an ecosystem that allows participants to grow their knowledge of both technical and nontechnical skills over time through their association with different projects and people. I trace the learning trajectories of two participants from high school until they enter the professional workforce and beyond. I argue that FLOSS participation represents an ideal networked form of learning as it provides both socio-cognitive support for short term activities and also socio-temporal support for long term participation and learning. It is a unique form of apprenticeship that exists concurrently with formal educational experiences but unlike traditional apprenticeship experiences it succeeds by spanning different spatialities - place/space and technology mix and temporal scales.,10.1145/3233391.3233541

+1894,Article,Knowledge management in OSS communities: Relationship between dense and sparse network structures,"Some authors in the literature have addressed knowledge transfer via weak ties between organization's units which are themselves strongly tied inside (e.g. Hansen, 1999). Some others have investigated knowledge management among open-source-software (OSS) developers and discussed factors influencing knowledge transfer within development teams (e.g. Joshi and Sarker, 2006). In the domain of open source software (OSS) communities, more companies are now attempting to establish relationships to benefit from these potential value-creating communities; and project managers could in fact target different goals within software development teams including knowledge transfer within and between teams. We step forward to distinguish knowledge transfer within groups as opposed to knowledge transfer between groups; where relevant projects are bundled into separate strongly intra-connected groups. In knowledge management literature there is a trade-off between sparse network structures (Burt, 2000, 2002) versus dense network structures (Walker et al., 1997; Coleman, 1988). It is argued that the former facilitates the diffusion and generation of ideas among groups, while the latter affects the implementation of idea within each dense group. To our best knowledge, there has been no study to investigate the relationship between dense and sparse network structures. We propose that knowledge transfer within dense groups has a positive influence on knowledge transfer between sparse groups, in that intragroup density, group size, developers centrality and betweenness could impact intergroup coupling. To prove our hypothesis, we use a complex network of open source software (OSS) as the domain of interest, where developers represent nodes and two developers contributing to a project task represent a network tie. Developers contributing to tasks in groups other than their own can explore novel ideas via sharing knowledge, whereas developers contributing to tasks inside groups exploit ideas to improve those projects. We investigate the idea both analytically and empirically within 4 months, 8 months and 1 year lagged time, and finally show that intragroup density has a positive whereas developers' centrality has a negative influence on intergroup coupling.",10.1016/j.ijinfomgt.2017.09.004

Design/methodology/approach - Data were collected using a structured questionnaire, and semi-structured in-depth interviews were conducted among 20 academic and 20 research libraries in Beijing, China. The convenient sampling technique was used to collect data. The data collected were interpreted using descriptive statistics and independent t-test. Findings - The results reveal that Chinese research and academics libraries depend mostly upon commercial software and place a great deal of trust on locally produced free software. This situation may be caused due to the lack of professional knowledge in OSS and lack of appropriate technical expertise. Although there were a sufficient number of librarians who have shown interest in OSS, they did not enthusiastically agree to implement it in their libraries. Furthermore, the interviews highlighted the professionals' opinion that most librarians are reluctant to adopt OSS due to the risk factor, lack of professional expertise, insufficient interest of the Chinese Government and lack of professional training. Originality/value - The findings are useful for the Chinese LIS community, software developers, technology administrators and library administrators. In particular, it is beneficial for research and academic libraries of China to adapt OSS for library management and provide better library services and sources to their library users.",10.1108/GKMC-03-2017-0022

Le premier, celui de l’immatériel, consiste à aborder le cyberespace comme un monde informationnel doté de propriétés distinctes de celles du monde physique. Le second, celui de la déterritorialisation, présente les collectifs en ligne comme détachés de tout ancrage territorial. L’article montre la manière dont ces lieux communs habitent la culture du logiciel libre, en revenant aux origines de celle-ci au sein du AI Lab du MIT, en examinant l’influence exercée sur elle par la pensée cybernétique et en analysant le processus d’extension et de globalisation du free software. L’article développe également une critique de ces topoï, en montrant qu’ils contribuent à occulter la continuité entre les transformations du monde numérique et celles du reste de la société. La conclusion revient sur l’essor récent du mouvement maker, fortement influencé par le logiciel libre, et met en avant la persistance des enjeux liés à la matière et au territoire, y compris au sein de la culture numérique.Alternate abstract:This article questions two ideas that have become commonplace in digital culture, and particularly in free software culture. The first one is the idea that cyberspace is an immaterial (or informational) space, exhibiting properties that are radically distinct from the ones of the material world. The second one is the idea of deterritorialization, according to which online communities are indifferent to the geographical reality of the territory. The article explains how these commonplace assumptions pervade free software culture, tracing their history back to cybernetics and the AI Lab at the MIT, and analyzing the globalization of free software culture since the 1990s. It also criticizes these topoï that often conceal how the transformations of the digital world are intertwined with the transformations of society at large.

+1903,Article,Motivating the contributions: An Open Innovation perspective on what to share as Open Source Software,"Open Source Software (OSS) ecosystems have reshaped the ways how software-intensive firms develop products and deliver value to customers. However, firms still need support for strategic product planning in terms of what to develop internally and what to share as OSS. Existing models accurately capture commoditization in software business, but lack operational support to decide what contribution strategy to employ in terms of what and when to contribute. This study proposes a Contribution Acceptance Process (CAP) model from which firms can adopt contribution strategies that align with product strategies and planning. In a design science influenced case study executed at Sony Mobile, the CAP model was iteratively developed in close collaboration with the firm's practitioners. The CAP model helps classify artifacts according to business impact and control complexity so firms may estimate and plan whether an artifact should be contributed or not. Further, an information meta-model is proposed that helps operationalize the CAP model at the organization. The CAP model provides an operational OI perspective on what firms involved in OSS ecosystems should share, by helping them motivate contributions through the creation of contribution strategies. The goal is to help maximize return on investment and sustain needed influence in OSS ecosystems. (C) 2017 The Authors. Published by Elsevier Inc.",10.1016/j.jss.2017.09.032

Communications and collaborations are essential for the success of projects. Usually, the most active and productive programmers are awarded with promotion to developers. To more effectively manage and progress the projects, it is important and beneficial to rank the programmers and thus, predict the developer candidates. In this work, we propose to combine machine learning techniques with existing complex network node ranking algorithms to improve the prediction results. Specifically, we have made the following contributions: (1), we have designed a novel machine learning-based classifier with significantly improved prediction performance; (2), we have constructed and tested various networks built based on the programmer email communication information; and (3), we have used real-world project data to compare different techniques and validate our methods.

This makes it difficult to conserve experimental metadata and track the analysis performed. It also complicates certain experimental approaches such as online analysis. To address this, we developed NeuroMatic, an open-source software toolkit that performs data acquisition (episodic, continuous and triggered recordings), data analysis (spike rasters, spontaneous event detection, curve fitting, stationarity) and simulations (stochastic synaptic transmission, synaptic short-term plasticity, integrate-and-fire and Hodgkin-Huxley-like single-compartment models). The merging of a wide range of tools into a single package facilitates a more integrated style of research, from the development of online analysis functions during data acquisition, to the simulation of synaptic conductance trains during dynamic-clamp experiments. Moreover, NeuroMatic has the advantage of working within Igor Pro, a platform-independent environment that includes an extensive library of built-in functions, a history window for reviewing the user's workflow and the ability to produce publication-quality graphics. Since its original release, NeuroMatic has been used in a wide range of scientific studies and its user base has grown considerably.

+1909,Article,Newcomers' Barriers. . . Is That All? An Analysis of Mentors' and Newcomers' Barriers in OSS Projects,"Newcomers' seamless onboarding is important for open collaboration communities, particularly those that leverage outsiders' contributions to remain sustainable. Nevertheless, previous work shows that OSS newcomers often face several barriers to contribute, which lead them to lose motivation and even give up on contributing. A well-known way to help newcomers overcome initial contribution barriers is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in OSS projects. Studying mentors' perspectives on the barriers that newcomers face play a vital role in improving onboarding processes; yet, OSS mentors face their own barriers, which hinder the effectiveness of the strategy. Since little is known about the barriers mentors face, in this paper, we investigate the barriers that affect mentors and their newcomer mentees. We interviewed mentors from OSS projects and qualitatively analyzed their answers. We found 44 barriers: 19 that affect mentors; and 34 that affect newcomers (9 affect both newcomers and mentors). Interestingly, most of the barriers we identified (66\\%) have a social nature. Additionally, we identified 10 strategies that mentors indicated to potentially alleviate some of the barriers. Since gender-related challenges emerged in our analysis, we conducted nine follow-up structured interviews to further explore this perspective. The contributions of this paper include: identifying the barriers mentors face; bringing the unique perspective of mentors on barriers faced by newcomers; unveiling strategies that can be used by mentors to support newcomers; and investigating gender-specific challenges in OSS mentorship. Mentors, newcomers, online communities, and educators can leverage this knowledge to foster new contributors to OSS projects.",10.1007/s10606-018-9310-8

+1919,Article,Optimized single-step (OSS) chemistry models for the simulation of turbulent premixed flame propagation,"A simple and efficient triple-optimization procedure (TOP) is introduced to determine single-step chemistry model parameters. The cornerstone of the proposed approach lies in the introduction of a fictive (or virtual) chemical species, the physical characteristics of which are set to recover some essential properties of combustion and flames. Special emphasis is presently placed on the capability of such a global kinetic scheme to recover three parameters that are recognized as the most influential in terms of turbulence chemistry interactions and turbulent premixed combustion regimes. These parameters are (i) the burnt gases temperature T-b, which settles the value of the thermal expansion factor tau = (T-b - T-u)/T-u, (ii) the propagation velocity delta(0)(L), which is mandatory to reproduce the flame dynamics, and (iii) the laminar premixed flame thickness delta(0)(L). In practice, the thermochemical properties of the fictive species (hereafter denoted by A(Phi)) are set to account for the impact of dissociation effects and partial oxidation of the fuel, i.e., presence of species other than H2O and CO2 in the burnt gases, which allows to recover a satisfactory estimate of T-b. The value of the pre-exponential factor associated to the single-step Arrhenius law is also optimized to reproduce the laminar flame propagation velocity. Finally, the transport characteristics are determined to recover a satisfactory estimate of the thermal flame thickness. The method is general in its principles and quite easy to implement. It is applicable to any couple of fuel and oxidizer. Attention is focused on the application of the method to any stoichiometry but it is also shown that the influence of both pressure and fresh reactants temperature can be recovered. The performance of the resulting optimized single step (OSS) chemistry models are assessed through a direct comparison with detailed chemistry results. Computations of one-dimensional laminar flames are performed with the OSS model using the cantera software for a wide range of pressure levels, fresh reactant temperatures, and equivalence ratios. Obtained results do show that the flame propagation velocity is correctly reproduced for the whole range of parameters, with a maximum value recovered in the vicinity of stoichiometry, a decrease towards rich conditions, and a satisfactory pressure dependence. Burnt gases temperature as well as thermal flame thickness values are also in excellent agreement with those issued from the reference detailed kinetics models. The OSS model is then used to perform direct numerical simulation (DNS) computations of flame kernel growths in both laminar and turbulent conditions. The comparison of obtained OSS results with detailed chemistry computations further confirms the relevance and performance of the proposed methodology. (C) 2018 The Combustion Institute.

Here, we have developed a grand potential-based nonlinear phase-field model to study the electrodeposition of lithium as relevant for a lithium metal anode, using open-source software package MOOSE. The dynamic morphological evolution under a large/small overpotential is studied in two dimensions, revealing important dendrite growth/stable deposition patterns. The corresponding temporal spatial distributions of ion concentration, overpotential, and driving force are studied, which demonstrate an intimate, dynamic competition between ion transport and electrochemical reactions, resulting in vastly different growth patterns. On the basis of the understanding from this model, we propose a ``compositionally graded electrolyte{''} with higher local ion concentration as a way to potentially suppress dendrite formation. Given the importance of morphological evolution for lithium metal electrodes, widespread applications of phase-field models have been limited in part due to in-house or proprietary software.

In this article, the bug closure process that is followed by a community of an open source software project is investigated in order to perform process conformance checking. Actual data that reveal the process steps have been extracted from the project's Bugzilla database and have been used as input in Disco process mining tool. The data includes extracted information for more than 19,000 bugs for the past 15 years in a csv form, formatted appropriately to construct an event log suitable for process mining. The extracted models have been compared to the process described in the project's blogs and wikis by the community.

The findings reveal that indeed the process followed in the OSS project is very similar to the declared one but variations do occur under specific circumstances. However, the process is not identical to the one proposed by Bugzilla suggesting that each OSS project can customize its processes in order to better address the needs of the project and the community.

Assessing and monitoring the dynamics of phenology is relevant to support several decisions in order to improve the efficiency of several farming practices. An open source application QPhenoMetrics - implemented in QGIS software that estimates vegetation phenology metrics is presented, using Earth Observation Systems (EOS) based time-series of Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) as proxies for phenology. QPhenoMetrics is characterized by freely-usable and updatable code, acceptance of satellite images or text formats, time-series analysis toolbox allowing the selection of region of interest with statistical quality assessment for Vegetation Indices (VI), and estimation of ensemble metrics. The application is structured in three components: (i) input data; (ii) pre-processing of the VI time-series and several fitting methods and (iii) computation of the phenological metrics. QPhenoMetrics produces a plot with the VI time-series and corresponding phenology metrics, and a spreadsheet is created with a list of NDVI or EVI values estimated using the selected fitting method. To evaluate the application, two main Portuguese crops, vineyards and maize, and MOD13 data from MODIS sensor during 2011-2012 were considered. QPhenoMetrics was validated with vineyard phenology observations (2007-2011). A comparative analysis with software products TimeSat and Spirits was also performed. It was concluded that QPhenoMetrics can be very useful for common users to extract phenology information for 16 daily MODIS data in HDF format, text files with NDVI/EVI data and ASCII files, through a simple and intuitive graphic interface.

+1929,Article,Quantitative diffusion measurements using the open-source software PyFRAP,"Fluorescence Recovery After Photobleaching (FRAP) and inverse FRAP (iFRAP) assays can be used to assess the mobility of fluorescent molecules. These assays measure diffusion by monitoring the return of fluorescence in bleached regions (FRAP), or the dissipation of fluorescence from photoconverted regions (iFRAP). However, current FRAP/iFRAP analysis methods suffer from simplified assumptions about sample geometry, bleaching/photo-conversion inhomogeneities, and the underlying reaction-diffusion kinetics. To address these shortcomings, we developed the software PyFRAP, which fits numerical simulations of three-dimensional models to FRAP/iFRAP data and accounts for bleaching/photoconversion inhomogeneities. Using PyFRAP we determined the diffusivities of fluorescent molecules spanning two orders of magnitude in molecular weight. We measured the tortuous effects that cell-like obstacles exert on effective diffusivity and show that reaction kinetics can be accounted for by model selection. These applications demonstrate the utility of PyFRAP, which can be widely adapted as a new extensible standard for FRAP analysis.",10.1038/s41467-018-03975-6

The main reason for this is the potential that it provides for reducing development effort and increasing the end-product quality.

However, up-to-date OSS reuse processes have mostly been opportunistic, leading to not fully capitalizing existing reuse potentials. In this study we propose a process (namely REACT) for improving planned OSS reuse practices, i.e., we define the activities that a software engineer can perform to reuse OSS artifacts. To illustrate the applicability of REACT, we provide an example, in which a mobile application is developed based upon the reuse of OSS artifacts. To validate the proposed process we compared the effort required to develop the application with and without adapting REACT process.

Drawing on signaling theory, this manuscript explores how third-party assessment can influence a developers' decision to join an OSS project. In order to test it, vignette survey study was conducted manipulating reputation, development experience, and a number of current OSS projects of existing developers in the OSS project. The findings suggest that all three signals have a positive influence on developer's decision to join the OSS project. This suggests that projects seeking to expand the number of contributing developers should consider offering information about its ``star developers{''}.",NA

The pipeline shows image quality comparable to a clinical system and backed by point spread function measurements a comparable resolution. Including all processing stages of a usual ultrasound pipeline, the run-time analysis shows that it can be executed in 2D and 3D on consumer GPUs in real time. Our software ultrasound pipeline opens up the research in image acquisition. Given access to ultrasound data from early stages (raw channel data, radiofrequency data), it simplifies the development in imaging. Furthermore, it tackles the reproducibility of research results, as code can be shared easily and even be executed without dedicated ultrasound hardware.",10.1007/s11548-018-1750-6

Increasingly complex simulations are used to assess similarities and differences between the two models' components. The simulations presented here are forced by ocean currents from a Finite Volume Community Ocean Model (FVCOM) implementation that has excellent skill in representing tidal motion, and with observed wind data that compensates for a coarse vertical ocean model resolution. The comprehensive comparison between GNOME and BLOSOM presented here, should aid modelers in interpreting their results. Beyond many similarities, aspects where both models are distinct are highlighted. Some suggestions for improvement are included, e.g., the inclusion of temporal interpolation of the forcing fields (BLOSOM) or the inclusion of a deflection angle option when parameterizing wind-driven processes (GNOME). Overall, GNOME and BLOSOM perform similarly, and are found to be complementary oil spill models. This paper also sheds light on what drove the historical Point Wells spill, and serves the additional purpose of being a learning resource for those interested in oil spill modeling. The increasingly complex approach used for the comparison is also used, in parallel, to illustrate the approach an oil spill modeler would typically follow when trying to hindcast or forecast an oil spill, including detailed technical information on basic aspects, like choosing a computational time step. We discuss our successful hindcast of the 2003 Point Wells oil spill that, to our knowledge, had remained unexplained. The oil spill models' solutions are compared to the historical Point Wells' oil trajectory, in time and space, as determined from overflight information. Our hindcast broadly replicates the correct locations at the correct times, using accurate tide and wind forcing. While the choice of wind coefficient we use is unconventional, a simplified analytic model supported by observations, suggests that it is justified under this study's circumstances. We highlight some of the key oceanographic findings as they may relate to other oil spills, and to the regional oceanography of the Salish Sea, including recommendations for future studies.",10.3390/jmse6030104
+1935,InProceedings,Software quality through the eyes of the end-user and static analysis tools: a study on Android OSS applications,"Source code analysis tools have been the vehicle for measuring and assessing the quality of a software product for decades. However, recently many studies have shown that post-deployment end-user reviews provide a wealth of insight into the quality of a software product and how it should evolve and be maintained. For example, end-user reviews help to identify missing features or inform developers about incorrect or unexpected software behavior. We believe that analyzing end-user reviews and utilizing analysis tools are a crucial step towards understanding the complete picture of the quality of a software product, as well as towards reasoning about the evolution history of it. In this paper, we investigate whether both methods correlate with one another. In other words, we explore if there exists a relationship between user satisfaction and the application's internal quality characteristics. To conduct our research, we analyze a total of 46 actual releases of three Android open source software (OSS) applications on the Google Play Store. For each release, we employ multiple static analysis tools to assess several aspects of the application's software quality. We retrieve and manually analyze the complete reviews after each release of each application from its store page, totaling 1004 reviews. Our initial results suggest that having high or low code quality does not necessary ensure user overall satisfaction.",10.1145/3194095.3194096

However, integrating external and internal sources of social capital is challenging and identifying appropriate integration strategies is crucial for the success of such endeavors. This study examines the simultaneous effects of external and internal sources of social capital, in the form of participant and project differences, and examines how they interact to influence OSS project success. We propose a taxonomy of participant differences (language, role, and contribution) and project differences (development environment and connectedness) and postulate their main and moderating effects on project success. Using a four-year panel data set of 329 SourceForge projects, we show that development environment difference has a curvilinear relationship with success and that connectedness reduces the positive impact of role and contribution diversity on project success. We also show that when development environment difference is moderate, the impact of role diversity is the most positive. We present the implications of these findings for theory and practice.",10.1016/j.jsis.2018.04.002

As a result, we discover that the statistical distribution of the number of developers corresponding to class files modification fellows approximately an exponential distribution. In addition, we analyze the features of function and structure of two kinds of class files and discover that both class files developed by developers who have too many modification behaviors to their projects and class files modified by too many developers tend to be more complex.

To explore and understand problems and challenges of current system requirement-OSS component matching and mismatches resolution practices in software development projects that integrate one or more OSS components into their software products. Semi-structured in-depth interviews with 25 respondents that have performed RE activities in software development projects that integrate OSS components in 25 different software development companies in Spain, Norway, Sweden, and Denmark. The study uncovers 15 observations regarding system requirements-OSS components matching and mismatch resolution practices used in industrial projects that integrate OSS components. The assessed projects focused mainly on pre-release stages of software applications that integrate OSS components in an opportunistic way. The results also provide details of a set of previously unexplored scenarios when solving system requirement-OSS component mismatches; and clarify some challenges and related problems. For instance, although licensing issues and the potential changes in OSS components by their corresponding communities and/or changes in system requirements have been greatly discussed in the RE literature as problems for OSS component integration, they did not appear to be relevant in our assessed projects. Instead, practitioners highlighted the problem of getting suitable OSS component documentation/information.",10.1007/s10664-017-9594-1

+1946,Article,THE IMPACT OF IDEOLOGY MISFIT ON OPEN SOURCE SOFTWARE COMMUNITIES AND COMPANIES,"Corporate involvement in open source software (OSS) communities has increased substantially in recent years. Often this takes the form of company employees devoting their time to contribute code to the efforts of projects in these communities. Ideology has traditionally served to motivate, coordinate, and guide volunteer contributions to OSS communities. As employees represent an increasing proportion of the participants in OSS communities, the role of OSS ideology in guiding their commitment and code contributions is unknown. In this research, we argue that OSS ideology misfit has important implications for companies and the OSS communities to which their employees contribute, since their engagement in such communities is not necessarily voluntary. We conceptualize two different types of misfit: OSS ideology under-fit, whereby an employee embraces an OSS ideology more than their coworkers or OSS community do, and OSS ideology over-fit, whereby an employee perceives that their coworkers or OSS community embrace the OSS ideology more strongly than the employee does. To develop a set of hypotheses about the implications of these two types of misfit for employee commitment to the company and commitment to the OSS community, we draw on self-determination theory. We test the hypotheses in a field study of 186 employees who participate in an OSS community. We find that OSS ideology under-fit impacts the company and the community in the same way: it decreases employee commitment to the company and commitment to the OSS community. In contrast, we find that OSS ideology over-fit increases commitment to the company but decreases commitment to the OSS community. Finally, we find that employees' commitment to their company reinforces the impact of their commitment to the OSS community in driving ongoing code contributions. This provides a holistic view of OSS ideology and its impacts among an increasingly pervasive yet understudied type of participant in OSS research. It provides insights for companies that are considering assigning their employees to work in OSS communities as well as for OSS communities that are partnering with these companies.",10.25300/MISQ/2018/14242

+1948,Article,The Clue of Life: Translating Feuerbach in George Eliot's The Mill on the Floss,"The central preoccupation of George Eliot's life was with religion. In her novels she searched for a view of life that would give modern man a sense of purpose, dignity and ethical direction. On reading Eliot's novels with the knowledge of her intellectual development, one must ask how this earnest agnostic could treat traditional religion so sympathetically, why she made the religious experience the subject of her creative work, and what moral truth she found religion to embody. It was the philosophy of the German anthropologist Ludwig Feuerbach, whose book The Essence of Christianity she translated in 1854, in combination with her own earlier experiences as a Christian, which led Eliot to her understanding of the subjective reality embodied in Christianity. `With the ideas of Feuerbach,' Eliot wrote, `I everywhere agree' (Haight, 1954-55, p.153). My paper attempts to show how the influence of Feuerbach achieves complexity and vitality in Eliot's novel The Mill on the Floss and how Eliot establishes her faith in firm and lasting relations, which could be attained through the adjustment of the individual to the community. This adjustment comes as a corollary to the protagonist's realization of the principles that promote love, respect, tolerance and sacrifice for others.",10.21659/rupkatha.v10n3.02

Six wideband grating modules combine to cover the full band at R=300, each couples a long slit with 60-190 beams on the sky. OSS will have a total of 120,000 background-limited detector pixels in the six 2-D arrays which provide spatial and spectral coverage.

+1951,Article,"The Types, Roles, and Practices of Documentation in Data Analytics Open Source Software Libraries","Computational research and data analytics increasingly relies on complex ecosystems of open source software (OSS) ``libraries{''} - curated collections of reusable code that programmers import to perform a specific task. Software documentation for these libraries is crucial in helping programmers/analysts know what libraries are available and how to use them. Yet documentation for open source software libraries is widely considered low-quality. This article is a collaboration between CSCW researchers and contributors to data analytics OSS libraries, based on ethnographic fieldwork and qualitative interviews. We examine several issues around the formats, practices, and challenges around documentation in these largely volunteer-based projects. There are many different kinds and formats of documentation that exist around such libraries, which play a variety of educational, promotional, and organizational roles. The work behind documentation is similarly multifaceted, including writing, reviewing, maintaining, and organizing documentation. Different aspects of documentation work require contributors to have different sets of skills and overcome various social and technical barriers. Finally, most of our interviewees do not report high levels of intrinsic enjoyment for doing documentation work (compared to writing code). Their motivation is affected by personal and project-specific factors, such as the perceived level of credit for doing documentation work versus more `technical' tasks like adding new features or fixing bugs. In studying documentation work for data analytics OSS libraries, we gain a new window into the changing practices of data-intensive research, as well as help practitioners better understand how to support this often invisible and infrastructural work in their projects.",10.1007/s10606-018-9333-1

Knowledge can be shared among individuals, groups, and organizations. A free software community is a type of community of practice arranged around a specific free software, where the knowledge shared is complex and the knowledge sharing processes have scarcely been studied. This investigation aims to identify the profiles of knowledge sharing processes in free software communities and examine how 6 motivations for sharing knowledge in free software communities are associated with each of the clusters. To accomplish this objective, a survey method was adopted, with 260 respondents belonging to free software communities. Cluster analysis was used to interpret the data. Four clusters were identified: Sporadic Sharer; Collector; Donator; and Constant Sharer. With the exception of the Sporadic Sharer, all the clusters presented high values of both collection and donation, including the Donators and Collectors. These results confirm the view of free software communities as communities of practice and highlight the importance of knowledge sharing in free software development cycle.

Bioinformatics, a core component of omics research, is one of the disciplines that first employed Free/Libre Open Source Software (FLOSS), and thus provided a fertile ground for its further development. Understanding the use and characteristics of FLOSS deployed in the omics field is valuable for future innovation strategies, policy and funding priorities. We conducted a bibliometric, longitudinal study of the use of FLOSS in sepsis omics research from 2011 to 2015 in the United States, EU-28 and China. Because sepsis is an interdisciplinary field at the intersection of multiple omics technologies and medical specialties, it was chosen as a model innovation ecosystem for this empirical analysis, which used publicly available data. Despite development of and competition from proprietary commercial software, scholars in omics continue to employ FLOSS routinely, and independent of the type of omics technology they work with. The number of articles using FLOSS increased significantly over time in the EU-28, as opposed to the United States and China (R=0.96, p=0.004). Furthermore, in an era where sharing of knowledge is being strongly advocated and promoted by public agencies and social institutions, we discuss possible correlations between the use of FLOSS and various funding sources in omics research. These observations and analyses provide new insights into the use of FLOSS in sepsis omics research across three (supra)national regions. Further benchmarking studies are warranted for FLOSS trends in other omics fields and geographical settings. These could, in time, lead to the development of new composite innovation and technology use metrics in omics systems sciences and bioinformatics communities.",10.1089/omi.2018.0032

+1963,InProceedings,Visualizing simulated temperatures of a complex object calculated with FTOM using open source software (BLENDER),"The Fraunhofer thermal object model (FTOM) predicts the temperature of an object as a function of the environmental conditions. The model has an outer layer exchanging radiation and heat with the environment and a stack of layers beyond modifying the thermal behavior. The orientation of the layer is defined by the normal vector of the surface. The innermost layer is at a constant or variable temperature called core temperature. All the layers have heat capacity and thermal conductivity. The outer layers properties are color (visible), emissivity (IR), coefficients of free and forced convection, and a factor for latent heat. The environmental parameters are air temperature, wind speed, relative humidity, irradiation of the sun, and thermal radiation of the sky and ground. The properties of the model (7 parameters) are fitted to minimize the difference between the prediction and a time series of measured temperatures. The size of the time series is one or more days with 288 values per day (5 minute resolution). The model is useable for very different objects like backgrounds (meadow, forest, rocks, sand, or bricks) or parts of objects like vehicles. The STANDCAM is a decoy of a vehicle and is used to constitute a thermal signature and is not classified. The STANDCAM has a complex CAD-Model with thousands of triangular facets that had to be simplified for the thermal simulation. The CAD model was available through WTD 52, an agency of the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw). Groups of elements of the model facing in the same direction and behaving similarly were cut out and grouped in distinct objects. The calculation of the temperature of the objects is based on measured environmental data and the model parameters are fitted on measured radiation temperatures of the objects and backgrounds. For the visualization the object is surrounded by a world texture. For the radiation temperature of the environment and the ground under the object measured air and meadow temperatures were used. The temperature is coded as a color from a palette (here we use a grey palette) and is updated regularly throughout the calculation of the scene for the selected view and is stored as a texture bitmap. The animation of the temperature textures is directly performed by BLENDER. The result of the visualization is available as movie that is watchable in real time or time lapse.",10.1117/12.2325380

+1966,Article,What Is Needed for the Sustainable Success of OSS Projects: Efficiency Analysis of Commit Production Process via Git,"The purpose of this study is to investigate the relative efficiency of open source software projects, and to analyze what is needed for their sustainable success. The success of open source software is known to be attributable to a massive number of contributors engaging in the development process. However, an efficient open source software project is not guaranteed simply by active participation by many; a coordination mechanism is needed to seamlessly manage the multi-party collaboration. On this basis, this study aimed to examine the internal regulatory processes based on Git and GitHub, which serve as such a mechanism, and redefine the efficiency of open source software projects to fully reflect them. For this purpose, a two-stage data envelopment analysis was used to measure the project efficiency reflecting the internal processes. Moreover, this study considered the Kruskal-Wallis test and Tobit regression analysis to examine the effects of the participation by many on an open source software project based on the newly defined efficiency. Results show that a simple increase in contributors can be poisonous in terms of the efficiency of open source software projects.",10.3390/su10093001
+1967,InProceedings,When Students Become Contributors: Leveraging OSS Contributions in Software Engineering Courses,"Traditional Software Engineering courses commonly prioritize the teaching of methodologies and concepts in small and controlled environments. This decision is partly justified by the difficulty of bringing real software projects to the classroom. The ubiquity of Open Source Software (OSS) projects contributes to mitigating this problem. Several instructors already make use of contribution to OSS as part of the teaching and evaluation process in their courses. However, little is known about how students perceive the approach of contributing to OSS projects in the context of a Software Engineering course. This paper aims to uncover challenges and benefits from the students' perspective. To achieve this, we conducted14 semi-structured interviews with students who attended to this kind of courses in five different Brazilian universities, resulting in findings not so well known. For example, we noticed that, although instructors point to the projects that students are required to contribute to, students (and the project community) are involved in the process of choosing projects and tasks (issues). We also identified that students' contributions vary in terms of number of lines added and removed in commits, as well as the use of different programming languages.",10.1145/3266237.3266250

We reveal their motivations to assume a key role in FLOSS projects (e.g., improving the projects because they are also using it), the project characteristics that most helped in their engagement process (e.g., a friendly community), and the barriers faced by the surveyed core developers (e.g., lack of time of the project leaders).

+1971,Article,``Computing{''} Requirements for Open Source Software: A Distributed Cognitive Approach,"Most requirements engineering (RE) research has been conducted in the context of structured and agile software development. Software, however, is increasingly developed in open source software (OSS) forms which have several unique characteristics. In this study, we approach OSS RE as a sociotechnical, distributed cognitive process where distributed actors ``compute{''} requirements- i.e., transform requirements-related knowledge into forms that foster a shared understanding of what the software is going to do and how it can be implemented. Such computation takes place through social sharing of knowledge and the use of heterogeneous artifacts. To illustrate the value of this approach, we conduct a case study of a popular OSS project, Rubinius-a runtime environment for the Ruby programming language-and identify ways in which cognitive workload associated with RE becomes distributed socially, structurally, and temporally across actors and artifacts. We generalize our observations into an analytic framework of OSS RE, which delineates three stages of requirements computation: excavation, instantiation, and testing-in-the-wild. We show how the distributed, dynamic, and heterogeneous computational structure underlying OSS development builds an effective mechanism for managing requirements. Our study contributes to sorely needed theorizing of appropriate RE processes within highly distributed environments as it identifies and articulates several novel mechanisms that undergird cognitive processes associated with distributed forms of RE.",10.17705/1jais.00525

It simulates the macro- and micromixing scales, and the complete energy and population balance equations during crystal nucleation and growth. The model is based on the Reynolds-Averaged-Navier-Stokes equation, coupled with a three-environment presumed probability density function model, and the spatially varying population balance equation semidiscretized using a high resolution finite-volume method. openCrys is implemented in C++ object oriented programming language using the open-source CFD package OpenFOAM. The software is used to compare the performance of dual impinging jet, coaxial, and radial crystallizers. It is shown that improving the micromixing does not necessarily result in a narrower crystal size distribution when temperature effects are taken into account. The complex interplay of crystallizer kinetics and momentum, mass, and heat transfer makes the selection of the best mixer for a particular application to be nonobvious, which motivates the development and application of high-fidelity multiscale simulations for the design of antisolvent crystallizers.",10.1021/acs.iecr.8b01849

+1976,Article,A Community Strategy Framework - How to obtain influence on requirements in meritocratic open source software communities?,"Context: In the Requirements Engineering (RE) process of an Open Source Software (OSS) community, an involved firm is a stakeholder among many. Conflicting agendas may create miss-alignment with the firm's internal requirements strategy. In communities with meritocratic governance or with aspects thereof, a firm has the opportunity to affect the RE process in line with their own agenda by gaining influence through active and symbiotic engagements. Objective: The focus of this study has been to identify what aspects that firms should consider when they assess their need of influencing the RE process in an OSS community, as well as what engagement practices that should be considered in order to gain this influence. Method: Using a design science approach, 21 interviews with 18 industry professionals from 12 different software-intensive firms were conducted to explore, design and validate an artifact for the problem context. Results: A Community Strategy Framework (CSF) is presented to help firms create community strategies that describe if and why they need influence on the RE process in a specific (meritocratic) OSS community, and how the firm could gain it. The framework consists of aspects and engagement practices. The aspects help determine how important an OSS project and its community is from business and technical perspectives. A community perspective is used when considering the feasibility and potential in gaining influence. The engagement practices are intended as a tool-box for how a firm can engage with a community in order to build influence needed. Conclusion: It is concluded from interview-based validation that the proposed CSF may provide support for firms in creating and tailoring community strategies and help them to focus resources on communities that matter and gain the influence needed on their respective RE processes.",10.1016/j.infsof.2019.04.010

More specifically, the software bug fixing process of OSS can be considered to show effects of the long-term operation and/or periodicity due to the multiple version-up procedures, in addition to the common reliability growth phenomenon observed in the relatively short-term software testing. In this article we propose a stochastic point process approach to represent the long-term effect and the periodicity effect of OSS with the actual OSS bug fixing data.

The paper provides an insight on the project life-span for a free open source software ecosystem. The statistical analysis of some project characteristics in GitHub is presented, and we find that the choices of programming languages, the number of files, the label format of the project, and the relevant membership expressions can impact the life-span of a project. Based on these discovered characteristics, we also propose a prediction model to estimate the project life-span in open source software ecosystems.

Therefore, it is important to establish the best software development and contributing practices early in the life-time of the project. Such practices should foster the contributors’ involvement in the OSS project as quickly as possible. The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors’ learning processes is an important research area in OSS.This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education. It is argued that collaboration with peers and consistent code contributions result in learning progress in OSS.

In this paper, we continue on this line of research by performing a large-scale empirical analysis of refactoring practices in 200 open source systems. Specifically, we analyze the change history of these systems at commit level to investigate: (i) whether developers perform refactoring operations and, if so, which are more diffused and (ii) when refactoring operations are applied, and (iii) which are the main developer-oriented factors leading to refactoring. Based on our results, future research can focus on enabling automatic support for less frequent refactorings and on recommending refactorings based on the developer's workload, project's maturity and developer's commitment to the project.

The data were obtained both from the National Vulnerability Database (NVD), and from project-specific web resources, which we monitor on a continuous basis.From that data, we extracted a dataset that maps 624 publicly disclosed vulnerabilities affecting 205 distinct open-source Java projects, used in SAP products or internal tools, onto the 1282 commits that fix them. Out of 624 vulnerabilities, 29 do not have a CVE (Common Vulnerability and Exposure) identifier at all, and 46, which do have such identifier assigned by a numbering authority, are not available in the NVD yet.The dataset is released under an open-source license, together with supporting scripts that allow researchers to automatically retrieve the actual content of the commits from the corresponding repositories, and to augment the attributes available for each instance. Moreover, these scripts allow to complement the dataset with additional instances that are not security fixes (which is useful, for example, in machine learning applications).Our dataset has been successfully used to train classifiers that could automatically identify security-relevant commits in code repositories. The release of this dataset and the supporting code as open-source will allow future research to be based on data of industrial relevance; it also represents a concrete step towards making the maintenance of this dataset a shared effort involving open-source communities, academia, and the industry.",10.1109/MSR.2019.00064
+1984,Article,A network-centric approach for estimating trust between open source software developers,"Trust between developers influences the success of open source software (OSS) projects. Although existing research recognizes the importance of trust, there is a lack of an effective and scalable computational method to measure trust in an OSS community. Consequently, OSS project members must rely on subjective inferences based on fragile and incomplete information for trust-related decision making. We propose an automated approach to assist a developer in identifying the trustworthiness of another developer. Our two-fold approach, first, computes direct trust between developer pairs who have interacted previously by analyzing their interactions via natural language processing. Second, we infer indirect trust between developers who have not interacted previously by constructing a community-wide developer network and propagating trust in the network. A large-scale evaluation of our approach on a GitHub dataset consisting of 24,315 developers shows that contributions from trusted developers are more likely to be accepted to a project compared to contributions from developers who are distrusted or lacking trust from project members. Further, we develop a pull request classifier that exploits trust metrics to effectively predict the likelihood of a pull request being accepted to a project, demonstrating the practical utility of our approach.",10.1371/journal.pone.0226281

Consequently, network management as we have known it up to now, with its silos and rigid approach, cannot meet these expectations. If we add the Internet of Things, the network has to become dynamic, adaptable and flexible. In this context, the industry and forums have specified and standardized a new architecture based on Software Defined Network (SDN), Network Function Virtualization, and Orchestration. These new paradigms, and especially Orchestration, will have a great impact on the Legacy Network Management Systems and the Operations Support System (OSS). We present a state of the art review of the main architecture approaches in the SDN standardization forums and discuss the place of the Orchestration in these different architectures. Then we focus on the Orchestration at the application layer and show how, together with SDN and Network Function Virtualization, they influence the Operation and Business Support Systems of next-generation network management.

+1988,Article,A systematic examination of knowledge loss in open source software projects: {SSIS},"Context Open Source Software (OSS) development is a knowledge focused activity which relies heavily on contributors who can be volunteers or paid workers and are geographically distributed. While working on OSS projects contributors acquire project related individualistic knowledge and gain experience and skills, which often remains unshared with others and is usually lost once contributors leave a project. All software development organisations face the problem of knowledge loss as employees leave, but this situation is exasperated in OSS projects where most contributors are volunteers with largely unpredictable engagement durations. Contributor turnover is inevitable due to the transient nature of OSS project workforces causing knowledge loss, which threatens the overall sustainability of OSS projects and impacts negatively on software quality and contributor productivity. Objective: The objective of this work is to deeply and systematically investigate the phenomenon of knowledge loss due to contributor turnover in OSS projects as presented in the state-of-the-art literature and to synthesise the information presented on the topic. Furthermore, based on the learning arising from our investigation it is our intention to identify mechanisms to reduce the overall effects of knowledge loss in OSS projects. Methodology: We use the snowballing methodology to identify the relevant literature on knowledge loss due to contributor turnover in OSS projects. This robust methodology for a literature review includes research question, search strategy, inclusion, exclusion, quality criteria, and data synthesis. The search strategy, and inclusion, exclusions and quality criteria are applied as a part of snowballing procedure. Snowballing is considered an efficient and reliable way to conduct a systematic literature review, providing a robust alternative to mechanically searching individual databases for given topics. Result: Knowledge sharing in OSS projects is abundant but there is no evidence of a formal strategy or practice to manage knowledge. Due to the dynamic and diverse nature of OSS projects, knowledge management is considered a challenging task and there is a need for a proactive mechanism to share knowledge in the OSS community for knowledge to be reused in the future by the OSS project contributors. From the collection of papers found using snowballing, we consolidated various themes on knowledge loss due to contributor turnover in OSS projects and identified 11 impacts due to knowledge loss in OSS projects, and 10 mitigations to manage with knowledge loss in OSS projects. Conclusion: In this paper, we propose future research directions to investigate integration of proactive knowledge retention practices with the existing OSS practices to reduce the current knowledge loss problem. We suggest that there is insufficient attention paid to KM in general in OSS, in particular there would appear to an absence of proactive measures to reduce the potential impact of knowledge loss. We also propose the need for a KM evaluation metric in OSS projects, similar to the ones that evaluate health of online communities, which should help to inform potential consumers of the OSS of the KM status on a project, something that is not existent today.",10.1016/j.ijinfomgt.2018.11.015

However, there is a lack of studies in literature that shed light into the evaluation of OSS by organizations. In this article, a method to evaluate reliability and maintainability of OSS by using both code-based and community-based aspects is proposed through the synthesis of existing studies in literature. To perform code-based evaluation, some internal attributes of the most recent quality model, ISO/IEC 25010, are selected and object-oriented C\\&K metrics are employed in an attempt to measure these attributes. To perform community-based evaluation, metrics derived from historical data such as e-mailing lists, problem reports, frequently asked questions, and etc. are utilized to identify and satisfy information needs as conformant to ISO/IEC 15939 standard for software measurement process. The two-dimensional method was used in selection of the Java build tools written in Java, and the results obtained by applying the proposed method and the results obtained by using OSMM and OpenBRR which are common methods in the literature were compared.

This paper serves as a non-trivial first step towards resolving this challenge by demonstrating a methodology and establishing knowledge to understand how the contributors' roles and their dynamics, reflected in the activities contributors perform, are exhibited in OSS communities. Based on an analysis of user action data from 29 GitHub projects, we extracted six activities that distinguished four Active roles and five Supporting roles of OSS contributors, as well as patterns in role changes.

The OSS community has some special characteristics (such as worldwide geographical distribution of both users and developers and missing resources) which are an obstacle to the direct adoption of many usability techniques as specified in the human-computer interaction (HCI) field. Objective: The aim of this research is to adapt and evaluate the feasibility of applying four usability techniques: user profiles, personas, direct observation and post-test information to four OSS projects from the viewpoint of the development team. Method: The applied research method was a multiple case study of the following OSS projects: Quite Universal Circuit Simulator, PSeInt, FreeMind and OpenOffice Writer. Results: We formalized the application procedure of each of the adapted usability techniques. We found that either there were no procedures for adopting usability techniques in OSS or they were not fully systematized. Additionally, we identified the adverse conditions that are an obstacle to their adoption in OSS and propose the special adaptations required to overcome the obstacles. To avoid some of the adverse conditions, we created web artefacts (online survey, wiki and forum) that are very popular in the OSS field. Conclusion: It is necessary to adapt usability techniques for application in OSS projects considering their idiosyncrasy. Additionally, we found that there are obstacles (for example, number of participant users, biased information provided by developers) to the application of the techniques. Despite these obstacles, it is feasible to apply the adapted techniques in OSS projects.",10.1016/j.infsof.2018.10.011

It is an open-source tool distributed under LGPL license, written in Java and based on the Chemistry Development Kit. Ambit-GCM provides an environment for creating models of molecular properties using additive schemes of zero, first or second orders. Ambit-GCM supports a set of local atomic attributes used for dynamic configuration of desired atom descriptions, which are applied to define fragments of different sizes. All defined groups are exhaustively generated for each molecule from a training set of compounds and combined to form the basic set of GCM fragments. Additionally, Ambit-GCM users can define correction factors via custom SMARTS notations or add externally calculated molecular descriptors. A molecular property model is obtained as a sum over all found groups by multiplying each group or correction factor frequency to its corresponding contribution. Multiple linear regression analysis (MLRA) is used for group contributions calculation. Ambit-GCM performs full statistical characterization of the obtained MLRA models via various validation techniques: external tests validation, cross validation, y-scrambling, etc. The software can be optionally used only for molecule fragmentation combined with an external statistical modelling package for further processing.

We argue that these aspects are important, however, technical security practice considering different social aspects of OSS development will assure the effectiveness and efficiency of the implementation of the tool. To mitigate this research gap, in this empirical study, we explore the current security culture in the OSS development phenomenon using a survey instrument with six evaluation dimensions: attitude, behavior, competency, subjective norms, governance, and communication. By exploring the current security culture in OSS communities, we can start to understand the influence of security on participants' security behaviors and decision-making, so that we can make realistic and practical suggestions.

+1999,Article,An open-source software analysis package for Microspheres with Ratiometric Barcode Lanthanide Encoding (MRBLEs),"Multiplexed bioassays, in which multiple analytes of interest are probed in parallel within a single small volume, have greatly accelerated the pace of biological discovery. Bead-based multiplexed bioassays have many technical advantages, including near solution-phase kinetics, small sample volume requirements, many within-assay replicates to reduce measurement error, and, for some bead materials, the ability to synthesize analytes directly on beads via solid-phase synthesis. To allow bead-based multiplexing, analytes can be synthesized on spectrally encoded beads with a 1:1 linkage between analyte identity and embedded codes. Bead-bound analyte libraries can then be pooled and incubated with a fluorescently-labeled macromolecule of interest, allowing downstream quantification of interactions between the macromolecule and all analytes simultaneously via imaging alone. Extracting quantitative binding data from these images poses several computational image processing challenges, requiring the ability to identify all beads in each image, quantify bound fluorescent material associated with each bead, and determine their embedded spectral code to reveal analyte identities. Here, we present a novel open-source Python software package (the mrbles analysis package) that provides the necessary tools to: (1) find encoded beads in a bright-field microscopy image; (2) quantify bound fluorescent material associated with bead perimeters; (3) identify embedded ratiometric spectral codes within beads; and (4) return data aggregated by embedded code and for each individual bead. We demonstrate the utility of this package by applying it towards analyzing data generated via multiplexed measurement of calcineurin protein binding to MRBLEs (Microspheres with Ratiometric Barcode Lanthanide Encoding) containing known and mutant binding peptide motifs. We anticipate that this flexible package should be applicable to a wide variety of assays, including simple bead or droplet finding analysis, quantification of binding to non-encoded beads, and analysis of multiplexed assays that use ratiometric, spectrally encoded beads.",10.1371/journal.pone.0203725

It is known that for the unidirectional composites the most significant distortion of the structure of the host material takes place when the optical fiber is embedded perpendicular to the direction of the reinforcement of the composite material layers. However, the internal structure of the composites with woven layer reinforcement scheme is significantly different. And the embedding of such a foreign object as an optical fiber can cause a basically other, as compared to unidirectional composites, change in the internal structure. Cross-sectional studies were performed using an optical microscope. The analysis of cross-sections of PCM samples was carried out with the aim of studying the changes in the structure of the layered composite with woven fabric reinforcement due to the embedding of the fiber-optic sensors. A comparison of the obtained images showed that the microstructure of the studied samples is better seen on polished surfaces. In the absence of polishing on a number of samples, the optical fiber is not visually noticeable or poorly distinguishable. Analysis of the obtained images showed that there is an insignificant distortion of the internal structure of the material in the area with embedded optical fiber without the formation of a resin pocket for all studied GFRP samples. At the same time, when analyzing CFRP samples, the effect of embedding of the optical fiber on the microstructure of the composite was not observed. 2019 The Authors.

+1001,Article,Application of Pharmacometrics in Pharmacotherapy: Open-Source Software for Vancomycin Therapeutic Drug Management,"The population pharmacokinetic (PK) parameters that are implemented in therapeutic drug management (TDM) software were generally obtained from a Western population and might not be adequate for PK prediction with a Korean population. This study aimed to develop a population PK model for vancomycin using Korean data to improve the quality of TDM for Korean patients. A total of 220 patients (1020 observations) who received vancomycin TDM services were included in the dataset. A population PK analysis was performed using non-linear mixed effects modeling, and a covariate evaluation was conducted. A two-compartment model with first-order elimination best explained the vancomycin PK, with estimates of 2.82 L/h, 31.8 L, 11.7 L/h, and 75.4 L for CL, V-1, Q, and V-2, respectively. In the covariate analysis, weight correlated with the volume of the peripheral compartment, and creatinine clearance, hemodialysis, and continuous renal replacement therapy treatments contributed to the clearance of vancomycin. The results show the clear need to optimize the PK parameters used for TDM in Korean patients. Specifically, V-1 should be smaller for Korean patients, and renal replacement therapies should be considered in TDM practice. This final model was successfully applied in R shiny as open-source software for Koreans.",10.3390/pharmaceutics11050224
+1002,Article,Aristotle vs. Ringelmann: On superlinear production in open source software,"Organizations exist because they provide additional production gains, in comparison to horizontal ways of allocating resources, such as markets (Coase, 1937), and the open source movement is deemed to be a new kind of peer-production organization somehow in between hierarchically organized firms and markets (Benkler, 2002). However, to strive as a new kind of organization, open source must provide production gains, which in turn should be measurable. The open source movement is particularly interesting to study for this reason. Here, we confront and discuss two contrasting views, which were reported in the literature recently. On the one hand, Sornette et al. (2014) uncovered a superlinear production mechanism, which quantifies Aristotle adage: ``the whole is more than the sum of its parts{''}. On the other hand, Scholtes et al. (2016) found opposite results, and referred to Maximilien Ringelmann, a French agricultural engineer (1861-1931), who discovered the tendency for individual members of a group to become increasingly less productive as the size of their group increases (Ringelmann, 1913). Since Ringelmann, the topic of collective intelligence has interested numbers of researchers in social sciences and social psychology (Woolley et al., 2010), as well as practitioners in management aiming at improving the performance of their team (Woolley et al., 2015). In most research and practice case studies, the Ringelmann effect has been found to hold, while, in contrast, the superlinear effect found by Sornette et al. is novel and may challenge common wisdom (Sornette et al., 2014). Here, we compare these two theories, weigh their strengths and weaknesses, and discuss how they have been tested with empirical data. We find that they may not contradict each other as much as was claimed by Scholtes et al. (2016). (C) 2019 Elsevier B.V. All rights reserved.",10.1016/j.physa.2019.04.130
+1003,InProceedings,Automating Patching of Vulnerable Open-Source Software Versions in Application Binaries,"Mobile application developers rely heavily on opensource software (OSS) to offload common functionalities such as the implementation of protocols and media format playback. Over the past years, several vulnerabilities have been found in popular open-source libraries like OpenSSL and FFmpeg. Mobile applications that include such libraries inherit these flaws, which make them vulnerable. Fortunately, the open-source community is responsive and patches are made available within days. However, mobile application developers are often left unaware of these flaws. The App Security Improvement Program (ASIP) is a commendable effort by Google to notify application developers of these flaws, but recent work has shown that many developers do not act on this information. Our work addresses vulnerable mobile applications through automatic binary patching from source patches provided by the OSS maintainers and without involving the developers. We propose novel techniques to overcome difficult challenges like patching feasibility analysis, source-code-to-binary-code matching, and in-memory patching. Our technique uses a novel variability-aware approach, which we implement as OSSPATCHER. We evaluated OSSPATCHER with 39 OSS and a collection of 1,000 Android applications using their vulnerable versions. OSSPATCHER generated 675 function-level patches that fixed the affected mobile applications without breaking their binary code. Further, we evaluated 10 vulnerabilities in popular apps such as Chrome with public exploits, which OSSPATCHER was able to mitigate and thwart their exploitation.",10.14722/ndss.2019.23126
+1004,InProceedings,B2SFinder: Detecting Open-Source Software Reuse in COTS Software,"COTS software products are developed extensively on top of OSS projects, resulting in OSS reuse vulnerabilities. To detect such vulnerabilities, finding OSS reuses in COTS software has become imperative. While scalable to tens of thousands of OSS projects, existing binary-to-source matching approaches are severely imprecise in analyzing COTS software products, since they support only a limited number of code features, compute matching scores only approximately in measuring OSS reuses, and neglect the code structures in OSS projects. We introduce a novel binary-to-source matching approach, called B2SFINDER1, to address these limitations. First of all, B2SFINDER can reason about seven kinds of code features that are traceable in both binary and source code. In order to compute matching scores precisely, B2SFINDER employs a weighted feature matching algorithm that combines three matching methods (for dealing with different code features) with two importance-weighting methods (for computing the weight of an instance of a code feature in a given COTS software application based on its specificity and occurrence frequency). Finally, B2SFINDER identifies different types of code reuses based on matching scores and code structures of OSS projects. We have implemented B2SFINDER using an optimized data structure. We have evaluated B2SFINDER using 21991 binaries from 1000 popular COTS software products and 2189 candidate OSS projects. Our experimental results show that B2SFINDER is not only precise but also scalable. Compared with the state of the art, B2SFINDER has successfully found up to 2.15x as many reuse cases in 53.85 seconds per binary file on average. We also discuss how B2SFINDER can be leveraged in detecting OSS reuse vulnerabilities in practice.",10.1109/ASE.2019.00100

Researchers have studied a wide variety of motivations behind individuals' participation in OSS communities. In this study, we build upon the framework, rooted in self-deterministic and social practice theories, proposed by von Krogh et al. (2012) and develop a model of OSS contribution likelihood. We empirically validate the model with a large dataset from 2017 GitHub Open Source Survey that includes over 5,500 randomly selected OSS developers. Results indicate that short-term and/or tangible motivations (carrots) and long-term, value-based factors (rainbows) influence OSS developers' contribution likelihood. However, carrots are relatively more important. Further, we find that as internal self-efficacy increases, effect of OSS hiring behind contribution to OSS decreases.

+1012,Article,"Comparative Characterization of Bacterial Communities in floss-Covered and Unvegetated Volcanic Deposits of Mount Merapi, Indonesia","Microbial colonization, followed by succession, on newly exposed volcanic substrates represents the beginning of the development of an early ecosystem. During early succession colonization by mosses or plants significantly alters the pioneer microbial community composition through the photosynthetic carbon input. To provide further insights into this process, we investigated the three-year-old volcanic deposits of Mount Merapi, Indonesia. Samples were collected from unvegetated (BRD) and moss-covered (BRUD) sites. Forest site soil (FRS) near the volcanic deposit-covered area was also collected for reference. An analysis of BRD and BRUD revealed high culturable cell densities (1.7-8.5 x10(5)CFU g(-1)) despite their low total C (<0.01\\%). FRS possessed high CFU (3 x10(6) g(-1)); however, its relative value per unit of total C (2.6\\%) was lower than that of the deposit samples. Based on the tag pyrosequencing of 16S rRNA genes, the BRD bacterial community was characterized by a higher number of betaproteobacterial families (or genus), represented by chemolithotrophic Methylophilaceae, Leptothrix, and Sulfuricellaceae. In contrast, BRUD was predominated by different betaproteobacterial families, such as Oxalobacteraceae, Comamonadaceae, and Rhodocyclaceae. Some bacterial (Oxalobacteraceae) sequences were phylogenetically related to those of known moss-associated bacteria. Within the FRS community, Proteobacteria was the most abundant phylum, followed by Acidobacteria, whereas Burkholderiaceae was the most dominant bacterial family within FRS. These results suggest that an inter-family succession of Betaproteobacteria occurred in response to colonization by mosses, followed by plants.",10.1264/jsme2.ME19041
+1014,InProceedings,Computation of Various Entropy Measures for Anticipating Bugs in Open-Source Software,"Bugs could be introduced at any phase of software development process. Bugs are recorded in repositories, which occur due to frequent changes in source code of software to meet the requirements of organizations or users. Open-source software is frequently updated and source codes are changed continuously due to which source code becomes complicated and hence bugs appear frequently. Bug repair process includes addition of new feature, enhancement of existing feature, some faults or other maintenance task. Entropy measures the uncertainty, thus helpful in studying code change process. In this paper, bugs reported in various subcomponents of Bugzilla open-source software are considered; changes are quantified in terms of entropies using Renyi, Havrda-Charvat, and Arimoto entropy measures of each component for all changes in components. A linear regression model using SPSS is applied to detect the expected bugs in the Bugzilla subcomponents.

Finding an appropriate task to start with is a common entrance barrier for newcomers. Poor code quality contributes to difficulties in the onboarding process and limits contributor satisfaction in general. In turn, dissatisfied developers tend to exacerbate problems with system integrity. Poorly designed systems are difficult to maintain and extend. Users can often directly experience these issues as instabilities in system behavior. Thus code quality is a key issue for users and contributors in FOSS. We present a case study on the interactions between code quality and contributor experience in the real-world FOSS project Catrobat.

Using Actor-Network Theory (ANT), we describe how coordination and power dynamics unfold among developers and how different tools and artifacts both display activities and mediate coordination efforts. Internal communication within an organization was reported to cause broken links in the community, duplication of work, and political tensions. ANT shows how tools and code can exercise agency and alter a software development process as an equivalently active actor of the scene. We discuss the theoretical and practical implications of the changing nature of open source software development.",NA

However (1) the adoption of BI tools remains relatively low (2) the acquisition costs of proprietary BI tools are relatively high and (3) the level of satisfaction with these BI tools remain low. Given the potential of open source BI (OSBI) tools, there is a need for analyzing barriers that prevent organizations from adopting OSBI. Drawing a systematic review and a Qualitative Survey of BI Experts, this study proposes a framework that categorizes and structures 23 barriers to OSBI adoption by organizations including 4 that were identified by BI Experts but not explicitly found in the literature.

+1019,Article,DEVELOPER CENTRALITY AND THE IMPACT OF VALUE CONGRUENCE AND INCONGRUENCE ON COMMITMENT AND CODE CONTRIBUTION ACTIVITY IN OPEN SOURCE SOFTWARE COMMUNITIES,"Open source software (OSS) communities are dependent on the code contributions of developers who, in many cases, never meet face-to-face and collaborate primarily through technology-enabled means. With their fluid membership, such communities often rely on engaging the commitment of developers to their cause. Given the changing nature of OSS communities, developers face barriers in appreciating appropriate ways of contributing to the collaborative effort. Such uncertainty about how to contribute results in OSS communities losing developers as they devote their attention to other, more welcoming, communities. In this research, we draw upon uncertainty reduction theory to argue that developers have two alternative avenues at their disposal to gain certainty about how to contribute: passive and interactive. Leveraging the person-environment fit perspective, we argue that congruence and incongruence in the OSS values of a developer and an OSS community serve as an avenue for passive approaches to gaining certainty, to the degree that appropriate ways of contributing are encoded in these values. Further, leveraging social network theory, we argue that centrality within a community's communication network constitutes an avenue for interactive approaches for gaining certainty about how to contribute. Using polynomial regression analysis, we analyze survey and archival data from 410 developers in an OSS community. Results suggest that developer centrality moderates the impact of congruence and incongruence in OSS values on commitment. Moreover, commitment fully mediates the impact of OSS value congruence and incongruence on developer contribution activity. We discuss the implications of our findings for research and practice.",10.25300/MISQ/2019/13928

Appropriate plaque control is therefore important. Dental floss is one instrument used to control plaque. The influence of guardians is an important factor in whether children use dental floss regularly. However, the use of dental floss among school-age children and the relationship between use and family background has yet to be examined. Aim: In this study, we conducted a questionnaire survey to examine rates of dental floss use and other related factors among elementary school children and their guardians. Methods: Surveys were sent to 298 guardians of children in grades 1-6 at an elementary school in Japan and 283 valid responses were received. Statistical analyses were carried out, with child's use of dental floss as a dependent variable and grade, sex, guardian assistance with child's tooth brushing, frequency of child's dental check-ups, and guardian's use of dental floss as independent variables. Results: The results revealed that 18.4\\% of children used dental floss compared with 52.7\\% of guardians, suggesting that the rate of usage among children is much lower than that among guardians. Logistic regression analysis further revealed that guardian's use of dental floss was significantly related to dental floss use among children. Conclusion: The guardian's use of dental floss was associated with dental floss use among their children in this group of Japanese elementary school. (C) 2019 Japanese Society of Pediatric Dentistry.

Creating such courses requires buy-in by deans, department chairs, and other faculty, who, because of lack of knowledge, can have little interest in supporting such efforts. Our poster shows how we solved this problem and created a means for students to simultaneously learn how to be contributors to FOSS projects and earn credit toward their major. It shows how we sought and found interested students and engaged them through repeated, informal meetings, which we used to gain the support of the chair and dean, and how we simulated a prototype course by having the students sign up for independent study credit. The group then met at regular intervals, communicated and shared work using discussion forums, source code repositories, and IRC chat. All course content is based on open source materials, including free textbooks, an abundance of on-line tutorials and reference materials, lecture notes and assignments that we wrote, with open source licenses, and other materials borrowed from http://foss2serve.org.

+1025,InProceedings,Diversity and Inclusion in Open Source Software (OSS) Projects: Where Do We Stand?,"Background: As the area of computing has thrived over the years, the participation of women in computing declined. Currently women represent less than 24\\% of the computing workforce and that number is declining. On the other hand, the ratios of women in Open Source Software (OSS) projects are even lower. Aims: The primary objective of this study is to determine the level of gender diversity among popular OSS projects and identify the presence of gender biases that may discourage females' participation. Method: On this goal, we mined the code review repositories of ten popular OSS projects. We used a semi-automated approach followed by a manual validation to identify the genders of the active contributors. Results: Our results suggest that lack of gender diversity remains an ongoing issue among all the ten projects as each of the projects had less than 10\\% female developers. However, many of the projects also suffer from lack of inclusion of females to leadership positions. Although none of the projects suggest significant differences between male and female developers in terms of productivity based on three different measures, data from three out of the ten projects indicate technical biases against female developers with lower code acceptance rates as well as delayed feedback during code reviews. However, biases against females are not universal as majority of the projects do not discriminate against females. The two projects with the least ratios of female contributors as core developers showed the most biases against females. Conclusion: Based on our findings, we conclude that promoting and mentoring females to leadership positions may be an effective solution to foster gender diversity.",NA

A Model of Coopetition in Community-initiated OSS Projects,"Background: An increasing number of commercial firms are participating in Open Source Software (OSS) projects to reduce their development cost and increase technical innovativeness. When collaborating with other firms whose sought values are conflicts of interests, firms may behave uncooperatively leading to harmful impacts on the common goal. Aim: This study explores how software firms both collaborate and compete in OSS projects. Method: We adopted a mixed research method on three OSS projects. Result: We found that commercial firms participating in community-initiated OSS projects collaborate in various ways across the organizational boundaries. While most of firms contribute little, a small number of firms that are very active and account for large proportions of contributions. We proposed a conceptual model to explain for coopetition among software firms in OSS projects. The model shows two aspects of coopetition can be managed at the same time based on firm gatekeepers. Conclusion: Firms need to operationalize their coopetition strategies to maximize value gained from participating in OSS projects.",10.5277/e-Inf190102
+1027,Article,Does Superposition Influence the Success of FLOSS Projects? An Examination of Open-Source Software Development by Organizations and Individuals,"Collaboration through open superposition describes the dominant work orchestration mechanism observed in free (Libre) and open-source (FLOSS) software, wherein the software development occurs by the sequential layering of individual tasks. This work orchestration mechanism is different from the traditional idea of software development, where the focus is toward cowork and concurrent development facilitated by a modular software design architecture. Our study theorizes and examines the motivational mechanisms that operate within superposed work structures to influence the success of FLOSS projects. We also unearth the contextual conditions that may limit the influence of the superposed nature of work on FLOSS project success. Furthermore, given the increasing use of FLOSS by organizations, we investigate the specificities brought to these motivational mechanisms when FLOSS projects are owned by organizations. The results from our analysis of over 6,500 FLOSS projects hosted on GitHub support a nonlinear relationship between the degree of superposition and the success of the FLOSS project. Moreover, we find that the type of ownership moderates this nonlinear relationship such that (1) organizational ownership mitigates the influence of the degree of superposition on the success of the project and that (2) under organizational ownership, the optimal degree of superposition (the point at which the success of the project is at a maximum) is lower than for individual-owned projects. This research advances our understanding of work structures, motivation, and organizational participation in FLOSS environments by describing the influence of task structures on the success of projects. The study also provides FLOSS practitioners with valuable insights for modeling project task structures to facilitate their success.",10.1287/isre.2018.0829

+1033,Article,"Ecohydrological consequences of tree removal in an urban park evaluated using open data, free software and a minimalist measuring campaign","With ongoing global climate change and an increasingly urbanized population, the importance of city parks and other forms of urban vegetation increases. Trees in urban parks can play an important role in mitigating runoff and delivering other ecosystem services. Park managers, E-NGOs, citizen scientists and others are increasingly called upon to evaluate the possible consequences of changes in park management such as, e.g., tree removal. Here, we present an unorthodox approach to hydrological modelling and its potential use in local policy making regarding urban greenery. The approach consists of a minimalist field campaign to characterize vegetation and soil moisture status combined with a novel model calibration using freely available data and software. During modelling, we were able to obtain coefficients of determination (R-2) of 0.66 and 0.73 for probe-measured and simulated soil moisture under tree stand and park lawn land covers respectively. The results demonstrated that tree cover had a significant positive effect on the hydrological regime of the locality through interception, transpiration and effects on soil moisture. Simulations suggested that tree cover was twice as effective at mitigating runoff than park lawn and almost seven times better than impervious surfaces. In the case of a potential replacement of tree vegetation in favour of park lawn or impervious surfaces an increase in runoff of 14\\% and 81\\% respectively could be expected. The main conclusion drawn from our study was that such an approach can be a very useful tool for supporting local decision-making processes as it offers a freely available, cheap and relatively easy-to-use way to describe the hydrological consequences of landcover change (e.g., tree removal) with sufficient accuracy.

This cross-sectional study was conducted with a sample of 402 preschool children aged 1-5 years, from Santa Cruz do Sul, a Southern city in Brazil. Mothers answered questions about environmental, demographic, and socioeconomic characteristics. Behavior variables as use of dental floss (study outcome) and dental attendance were also evaluated. Poisson regression analysis with robust variance through a hierarchical approach was used to investigate the association of explanatory variables for use of dental floss. Prevalence ratio (PR) and 95\\% confidence intervals (95\\%CI) were estimated. The mean sample age was 3.32 years (standard deviation {[}SD] 1.10). Of the included children, 291 (73.12\\%) did not use dental floss. The environmental model indicated that children who attended daycare (PR 2.53; 95\\%CI 1.39-4.60) and those whose parents were members of volunteer networks (RP 1.58; 95\\%CI 1.02-2.46) were more likely to use dental floss. Children from families with higher income (PR 1.55; 95\\%CI 1.07-2.24) and maternal schooling (PR 2.21; 95\\%CI 1.31-3.74) presented a higher prevalence of dental floss use. Older children and those who attended dental services were also related to higher dental floss use. Our findings suggest that children who live in a supporting environment and those with a higher socioeconomic status are more likely to use dental floss.",10.1590/1807-3107bor-2019.vol33.0096
+1035,Article,ElectroMap: High-throughput open-source software for analysis and mapping of cardiac electrophysiology,"The ability to record and analyse electrical behaviour across the heart using optical and electrode mapping has revolutionised cardiac research. However, wider uptake of these technologies is constrained by the lack of multi-functional and robustly characterised analysis and mapping software. We present ElectroMap, an adaptable, high-throughput, open-source software for processing, analysis and mapping of complex electrophysiology datasets from diverse experimental models and acquisition modalities. Key innovation is development of standalone module for quantification of conduction velocity, employing multiple methodologies, currently not widely available to researchers. ElectroMap has also been designed to support multiple methodologies for accurate calculation of activation, repolarisation, arrhythmia detection, calcium handling and beat-to-beat heterogeneity. ElectroMap implements automated signal segmentation, ensemble averaging and integrates optogenetic approaches. Here we employ ElectroMap for analysis, mapping and detection of proarrhythmic phenomena in silico, in cellulo, animal model and in vivo patient datasets. We anticipate that ElectroMap will accelerate innovative cardiac research and enhance the uptake, application and interpretation of mapping technologies leading to novel approaches for arrhythmia prevention.",10.1038/s41598-018-38263-2

Research has been done to promote techniques and tools for providing open source developers with innovative features aiming at obtaining improvements in terms of development effort, cost savings, and developer productivity, just to mention a few. In the context of the EU H2020 CROSSMINER project we are conceiving a set of recommendations to assist software programmers in different phases of the development process. To this end, we defined a graph-based representation to encode in a homogeneous manner different aspects of OSS ecosystems as well as to incorporate various well-founded recommendation techniques. Following the proposed paradigm, we have implemented recommender systems for providing various artifacts, such as third-party libraries and API usage. The preliminary results we achieved so far are promising: our proposed systems are able to suggest highly relevant items with respect to the current development context. In this paper, we describe what has been achieved so far as well as our planned medium and longer-term objectives. As a proof of concept, we present a use case where we built a context-aware recommender system to recommend API function calls and usage patterns.",10.1145/3319008.3319353
+1040,Article,Endoscopic Resection of Gastric Submucosal Masses by a Dental Floss Traction Method,"Background and Aims. ESE (endoscopic submucosal excavation) is widely used for the treatment of digestive diseases. The dental floss traction (DFT) method has been successfully used to facilitate ESE to resect mucosal lesions such as early gastric cancer. DFT has not been used in ESE to remove submucosal masses. This study aimed to examine the efficacy of DFT-assisted ESE (DFT- ESE) for the removal of submucous masses. Methods. From March 2017 to May 2017, a total of 12 patients with gastric submucosal masses at the First Affiliated Hospital of Nanchang University, Jiangxi, China, were enrolled. The tumor characteristics, en bloc resection rates, complications, and outcomes on follow-up were evaluated for all patients. Results. The 12 submucosal tumors were completely removed by DFT- ESE. Nine were gastrointestinal stromal tumors. Two were Schwannoma, located in the greater curvature of the gastric corpus. One was gastric ectopic pancreas. All the resected tumors were removed completely with intact tumor capsules. There was no more bleeding or perforation after the endoscopic closure of the perforation or the wound after the DFT-ESE, and no recurrences were identified at the time of follow-up. Conclusions. The DFT method efficiently and safely facilitated the ESE procedure during the resection of gastric submucosal tumors. This study was registered with Chinese Clinical Trial Registry under Registration number ChiCTR-OOC-15005833).",10.1155/2019/1083053

While many educators use open source resources for teaching, there seems to be few contributions to such projects of students as part of their university courses. In this work we present our experience on establishing open source development from student contributors as part of their university curriculum. Since 2010 more than 300 students from Graz University of Technology have been involved in the presented Catrobat project and have gained knowledge about agile software development as well as several related domains, e.g., project management, marketing, or graphical design.

As we conclude, bringing open source to university courses is an effective practical approach based on social learning and provides benefits for students and researchers.",NA
+1042,Article,Enhancing C/C plus plus based OSS development and discoverability with CBRJS: A Rust/Nodejs/WebAssembly framework for repackaging legacy codebases,"Since the appearance of the C programming language and later C++, a plethora of libraries have been developed in both languages. Unfortunately, discovering such Open Source Software (OSS) components efficiently is not always an easy task. Nonetheless, recent advancements in OSS technologies present an opportunity to improve the status quo. In this paper, we introduce a prototype framework, which utilizes the Rust and JavaScript programming languages, as well as their respective ecosystems, alongside the WebAssembly state-of-the-art Web standard, for achieving boosted exposure for hard-to-find C/C++ OSS components, by taking advantage of their package discovery and delivery channels. By demonstrating how this system works, we show that this methodology is capable of increasing the exposure of such libraries, and providing a modernized stage for further development and maintenance. Provided metrics exhibit a more than twofold increase in downloads for a re-packaged library, superior discoverability compared to standard public OSS code repositories, as well as evidence that Web browser vendors invest heavily in optimizing the underlying runtime.

+1043,InProceedings,Evolutionary Analysis of Developer Collaboration Network in Cloud Foundry OSS Community,"The collaborative pattern of developers in OSS (Open Source Software) communities is a research-hotspot in the academic circle. However, the existing researches mainly concern the static features of the communication network of community members, and few studies involve the structural evolution of developer collaboration network in OSS communities. This paper constructs the developer collaboration network of the Cloud Foundry OSS community by coding-collaboration relationships, and then analyses the structure and evolution of the constructed network. The results show that a modular pattern centering on a few developers gradually emerges in the developer collaboration network after an evolutionary process of three stages. Core developers have completed a large proportion of the development work and played a coordinating role in development activities, while the periphery developers submit code to specific sub-projects according to their technical background, which complements the core developers' work. Furthermore, the modules of the developer collaboration network are intrinsically related to the sub-projects and continuously contribute code for the corresponding subprojects during the evolutionary process. These results may deepen our understandings of the collaborative pattern of OSS communities, and also have some reference value for the studies of open collaborative innovation in large scale crowds.",10.1007/978-981-15-1209-4\\_7

The animals were implanted biovitroceramics PAW-1 in the mandible in the form of spongy matrix composed of fluorhydroxyapatite and microcrystallized wollastonite in a glass matrix, elaborated by the company PONETI (Romania) and Geistlich Bio-Oss-Collagen in the form of block (a mixture of granules, 0.25-1mm in size) and 10\\% fibers of porcine collagen. Geistlich Bio-Oss Collagen is a natural mineral bone of bovine origin, comparable both chemically and structurally to the mineralized human bone. It has a spongy consistency that allows simple modeling, and collagen facilitates the adaptation of the material on the defect site. The biochemical blood analysis showed an increased activity of bone thermolabile alkaline phosphatase over 30 days, the maximum being reached over 60 days + 20\\% (p< 0.05) from the beginning of the experiment. The activity of tartrate-resistant bone acid phosphatase, on the contrary, decreased veridically by 22\\% over 60 days after implantation.

+1045,Article,Exploring and Expanding GSE Education with Open Source Software Development,"Global software engineering (GSE) courses traditionally require cooperation between at least two universities so as to provide a distributed development environment to the students. In this study, we explore an alternative way to organize a global software engineering course where students work on open source software development (OSSD) projects rather than in a multi-university collaboration setting. The results show that the new setup may provide core GSE challenges as well as challenges associated with software development outsourcing and challenges related to working on large open source software. The present article compares the experiences gained from running a combined GSE and OSSD course against the experiences gained from running a traditional GSE course. The two alternatives are compared in terms of students' learning outcomes and course organization. The authors found that a combined GSE and OSSD course provides learning opportunities that are partly overlapping with, and partly complementary to, a traditional GSE course. The authors also found that the combined OSSD and GSE course was somewhat easier to organize because most of the activities took place in a single university setting. The authors used the extended GSE taxonomy for the comparison and found it to be a useful tool for this, although it had some limitations in expressive power. Therefore, two additional relationship dimensions are proposed that will further enrich the extended taxonomy in classifying GSE (and OSSD) projects.",10.1145/3230012

These include controlling user access to systems, resources, and data security issues that encompass secure storage, secure transmission, data authenticity and data integrity. These requirements are met by establishing the right policies, controls, and mechanisms that are put in place to effectively protect sensitive data. Therefore, this research aims to see if open source software has the potential to influence the cybersecurity market that is currently dominated by proprietary software. However, in order to accomplish such a task, certain conditions must be met. Such as understanding of the history behind open source software, the positive and negative influences it carries when dealing with this type of software. As well as compare and contrast current proprietary solutions with open source solutions, in order to grasp the potential economic impact of open source software leading onwards into the future. The ideal findings would be to outline the factors that are holding back open source software, and whether these factors are adjustable or correctable over time. Another aim is to highlight the potential financial benefit that comes from switching to or prioritizing OSS security solutions.

+1048,InProceedings,FINE SPATIAL SCALE MODELLING OF TRENTINO PAST FOREST LANDSCAPE (TRENTINOLAND): A CASE STUDY OF FOSS APPLICATION,"Trentino is an Italian alpine region (about 6200 Km(2)) with a forest coverage exceeding 60\\% of its whole surface. In the past, forest landscape has changed dramatically, especially in periods of forest over-exploitation. Previous studies in some Trentino sub-regions (Val di Fassa, Paneveggio) have identified these changes and the current trend of forest growth at the expenses of open areas, such as pastures and grasslands, due to the abandonment of rural areas. This phenomenon leads to the rapid Alpine landscape change and profoundly affects the ecological features of mountain ecosystems. To be able to monitor and to take future actions about this trend it is fundamental to know in detail the historical situation of the progressive changes on the land use that occurred over Trentino. The work aims to comprehensively reconstruct the forest cover of whole Trentino at high resolution (5m x 5m pixels) using a series of maps spanning a long period, consisting in historical maps, aerial images, remote sensed information and historical archives. The datasets were archived, processed and analyzed using the Free and Open Source Software (FOSS) GIS GRASS and QGIS. Historical maps include Atlas Tyrolensis (dated 1770), Theresianischer Kataster (dated 1859) and Italian Kingdom Forest Map (IKFM) of 1936. The aerial imagery dataset includes aerial images taken in 1954, which have been orthorectified during this research, and orthophotos available for years 1973, 1994, 2000, 2006, 2010 and 2016. Remote sensed information includes Landsat and recent Lidar data, while historical archives consist mostly in Forest Management Plans available since around 1950. The versatility of the wide variety of modules supplied from the FOSS GRASS and QGIS enabled to perform a diverse set of analysis and pre-processing (e.g.:orthorectification) on a heterogeneous dataset of input images. We will focus on the different strategies and methodologies implemented in the FOSS GIS used to process the various types of geographic data, challenges for the future of the research and the fundamental role of the FOSS systems in this process. Quantifying forest change in the time-span of our dataset can be used to perform further analysis on ecosystem services, such as protection from soil erosion, and on modification of biome diversity and to create future change scenarios.",10.5194/isprs-archives-XLII-4-W14-71-2019
+1049,InProceedings,FLOSS FAQ chatbot project reuse - how to allow nonexperts to develop a chatbot,"FAQ chatbots possess the capability to provide answers to frequently asked questions of a particular service, platform, or system. Currently, FAQ chatbot is the most popular domain of use of dialog assistants. However, developing a chatbot project requires a full-stack team formed by numerous specialists, such as dialog designer, data scientist, software engineer, DevOps, business strategist and experts from the domain, which can be both time and resources consuming. Language processing can be particularly challenging in languages other than English due to the scarcity of training datasets. Most of the requirements of FAQ chatbots are similar, domain-specific, and projects could profit from Open Source Software (OSS) reuse. In this paper, we examine how OSS FAQ chatbot projects can benefit from reuse at the project level (black-box reuse). We present an experience report of a FLOSS FAQ chatbot project developed in Portuguese to an e-government service in Brazil. It comprises of the chatbot distribution service, as well as for analytics tool integrated and deployed on-premises. We identified assets that could be reused as a black-box and the assets that should be customized for a particular application. We categorized these assets in architecture, corpus, dialog flows, machine learning models, and documentation. This paper discusses how automation, pre-configuration, and templates can aid newcomers to develop chatbots in Portuguese without the need for specialized skills required from tools in chatbot architecture. Our main contribution is to highlight the issues non-English FAQ chatbots projects will likely face and the assets that can be reused. It allows non-chatbot experts to develop a quality-assured OSS FAQ chatbot in a shorter project cycle.",10.1145/3306446.3340823

Aims: In this paper, we examine the extent to which these problems still exist. We also study male and female contributors' perceptions of other contributors. Method: We surveyed participants from 15 FLOSS projects, asking a series of open-ended, closed-ended, and behavioral scale questions to gather information about the issue of gender in FLOSS projects. Results: Though many of those we surveyed expressed a positive sentiment towards females who participate in FLOSS projects, some were still strongly against their inclusion. Often, the respondents who were against inclusiveness also believed their own sentiments were the prevailing belief in the community, contrary to our findings. Others did not see the purpose of attempting to be inclusive, expressing the sentiment that a discussion of gender has no place in FLOSS. Conclusions: FLOSS projects have started to move forwards in terms of gender acceptance. However, there is still a need for more progress in the inclusion of gender-diverse contributors.",10.1109/ICSE.2019.00077

Therefore, understanding how and why it occurs is important. To date, researchers have examined code reuse in OSS largely from the perspective of leaders. We show why followers must be considered as well. ``Followers{''} are people who have had previous contacts with an individual from another project and who continue to associate with him or her. We consider two types of followers: developers (those directly involved in software development) and observers (those indirectly involved in it). We conduct a series of empirical investigations by using a longitudinal dataset of OSS projects hosted in GitHub, along with a survey and qualitative data. We find that followership can affect code reuse, but the effect depends on the nature of the follower (developer or observer). Overall, our study suggests that followership is important for code reuse in OSS because it enables participants to learn, and learning promotes code reuse.",10.25300/MISQ/2019/14043

Two feature that makes them particularly attractive are their interactive nature and easy testing during the model development process. However, they are less suited for operation as production level models due to their slow simulation performance. This paper presents a new extension to the EDD that offers C++ model performance coupled with the convenience of EDD modelling. The extended form of the EDD is called a Verilog-A EDD or VAEDD for short. It has the same structure as the standard EDD but is built around compiled Verilog-A module code, which in turn is translated to C++ code and dynamically linked to the main body of the simulator code. Essentially a VAEDD is a tiny Verilog-A module with a standardised internal code structure. To demonstrate the interactive approach to compact model building with VAEDD components the design and testing of a high power SiC Schottky barrier diode is included in the main body of the text.",10.23919/mixdes.2019.8787063

As such access to PHC services is an important factor to ensure good health of a community. While the need to provide equal and easy access to PHC is well understood, the approaches informing the decision-making process to improve the access tend to face a number of challenges in the developing world. Use of conventional Information and Communication Technologies (ICTs) comes with requisite financial costs which Free and Open Source Software (FOSS) ICT technologies have the potential to help lower among other benefits. In this study, the confluence of spatial accessibility tools provided by FOSS technologies, specifically PostgreSQL/PostGIS and QGIS, was explored to inform decision making in PHC accessibility in Zomba, Malawi. The results show that the household population (P) that is within the threshold time was 8, representing \\% of all households having access to health care. The mean accessibility score for the district was 0.010 and ranged from 0.00 to 0.231. While the findings provide, arguably, spatially objective PHC accessibility data to inform policy direction and also reveals accessibility to PHC in Malawi to be lower than reported, the study also reveals the usefulness of FOSS technologies, in the developing world. Use of FOSS facilitated incremental setup of the model thereby allowing to run the model with limited processing power.

+1061,Article,Flux Puppy - An open-source software application and portable system design for low-cost manual measurements of CO2 and H2O fluxes,"Manual chamber-based measurements of CO2 (and H2O) fluxes are important for understanding ecosystem carbon metabolism. Small opaque chambers can be used to measure leaf, stem and soil respiration. Larger transparent chambers can be used to measure net ecosystem exchange of CO2, and small jars often serve this purpose for laboratory incubations of soil and plant material. We developed an Android application (app), called Flux Puppy, to facilitate chamber-based flux measurements in the field and laboratory. The app is designed to run on an inexpensive handheld Android device, such as a tablet or phone, and it has a graphical user interface that communicates with a LI-COR LI-820 and LI-830 (CO2) or LI-840 and LI-850 (CO2/H2O) infrared gas analyzer. The app logs concentrations of CO2 and H2O, cell temperature and pressure at 1 Hz, displays the output graphically, and calculates the linear regression slope, R-squared, and standard error of the CO2 time series. A metadata screen allows users to enter operator, site, and plot information, as well as take a photograph using the Android device's built-in camera, and log measurement location using the device GPS. Additionally, there is a notes field, which can be revised after the measurements are taken. Data files (the 1 s raw data, photograph, and metadata including statistics calculated from the raw data) are then transmitted off the device through file sharing options (Gmail, Outlook, Google Drive, Dropbox etc.). Because Flux Puppy code is open-source (available on GitHub) and the flux measurement system we describe is relatively inexpensive and straightforward to assemble, it should be of broad interest to the carbon cycling community.",10.1016/j.agrformet.2019.04.012

+1065,Article,Gendered behavior as a disadvantage in open source software development,"Women are severely marginalized in software development, especially in open source. In this article we argue that disadvantage is more due to gendered behavior than to categorical discrimination: women are at a disadvantage because of what they do, rather than because of who they are. Using data on entire careers of users from GitHub.com, we develop a measure to capture the gendered pattern of behavior: We use a random forest prediction of being female (as opposed to being male) by behavioral choices in the level of activity, specialization in programming languages, and choice of partners. We test differences in success and survival along both categorical gender and the gendered pattern of behavior. We find that 84.5\\% of women's disadvantage (compared to men) in success and 34.8\\% of their disadvantage in survival are due to the female pattern of their behavior. Men are also disadvantaged along their interquartile range of the female pattern of their behavior, and users who don't reveal their gender suffer an even more drastic disadvantage in survival probability. Moreover, we do not see evidence for any reduction of these inequalities in time. Our findings are robust to noise in gender recognition, and to taking into account particular programming languages, or decision tree classes of gendered behavior. Our results suggest that fighting categorical gender discrimination will have a limited impact on gender inequalities in open source software development, and that gender hiding is not a viable strategy for women.",10.1140/epjds/s13688-019-0202-z
+1066,Article,Gendered work culture in free/libre open source software development,"This article adopts a feminist perspective to examine masculine work culture in the development of free/libre open source software. The authors draw on a case study of the Heidi bug' discovered during the development of the Mozilla Firefox web browser to examine how gendered talk' was (en)-acted to facilitate bricolage' in an online work environment. Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender-balanced, women-friendly and inclusive workplace certainly would benefit from a more diverse environment. This article highlights the gendered aspect of software development through examining the language use and mainstream bricolage' practice, and establishes a compelling ground for enlarging the talent pool to include more women and integrating gender ethics (e.g., raising awareness of sensitive language and design approaches) into computer ethics education.",10.1111/gwao.12255

In spite of having these benefits, numerous challenges can be faced during the multi-release OSS development. Some of the challenges can be the generation of errors during the addition of new features. To address the changing fault detection process, a change point phenomenon is considered so as to give more practicality to the model. In this article, we present a general framework for multi-release OSS modelling incorporating imperfect debugging and change points. Parameter estimation and model validation is done on the three releases of Apache, an open source software project.",10.4018/IJSI.2019100105

While it is important for them to understand the technology trends in the rapidly changing computer science and data science fields, it takes considerable time and knowledge to acquire good information about these trends. Particularly, data/computer scientists with little experience in the field find it difficult to obtain information on such trends. Therefore, we propose a visualization system that can easily and quickly explore the technology trends in computer and data science. This study aims to identify the key technologies and developers in a specific field, and other technologies deeply related to specific technologies, and explore the changes in popularity of technologies, languages, and libraries over time. This study includes two case studies to obtain information using the proposed visualization. We demonstrate our system with GitHub repositories data.",10.1109/PacificVis.2019.00028
+1072,Article,How Companies Use OSS Tools Ecosystems for Open Innovation,"Moving toward the open innovation (OI) model requires multifaceted transformations within companies. It often involves giving away the tools for product development or sharing future product directions with open tools ecosystems. Moving from the traditional closed innovation model toward an OI model for software development tools shows the potential to increase software development competence and efficiency of organizations. We report a case study in software-intensive company developing embedded devices (e.g., smartphones) followed by a survey in OSS communities such as Gerrit, Git, and Jenkins. The studied branch focuses on developing Android phones. This paper presents contribution strategies and triggers for openness. These strategies include avoid forking OSS tools, empower developers to participate in the ecosystem, steer ecosystems through contributions, create business through differentiation, and create new ecosystems. The triggers of openness are from 30 different companies with examples. Finally, openness requires a cultural change aligned with strategies and business models.",10.1109/MITP.2019.2893134

An important open question is related with the investigation of how undergraduate students perceive the relevance of open source software literature. To address this question, we conducted a survey at University of Brasilia (UnB) where 500 undergraduate students were invited to rate the relevance of research ideas contained in papers that were published over a period of ten years. This paper attempts to investigate whether the Open Source Software research produces results considered relevant to undergraduate students. This way we can provide feedback from the students, offering a way to produce useful and, consequently, more disseminated works among Open Source practitioners. To answer about the relevance of available work, we have tackled two questions: one about the scope of the studies and another about the quality perceived by them. For the first one, a systematic mapping was conducted, revealing a set of works composed by a great diversity of results. Than, we applied a Survey in which students could evaluate the relevance of these gathered works. The available open source software research works seem to be very diverse and were considered useful for students that contribute to the Open Source Projects. 77.01\\% of respondents answered that research conducted in the Open Source Community is relevant and important to the community, as well as to their professional and academic lives.",10.1145/3350768.3351994

The aeration coefficient of the flow from the lower surface (inside the cavity)(beta(lower)) is a function of non-dimensional numbers which aerator geometry parameters such as cavity length to ramp height L-c/t(r) is considered as one of the most important parameters. Therefore, in the present study, OpenFOAM software and RNG k-epsilon turbulence model were used to simulate the flow to study the aeration effect on flow characteristics, so the range of aeration coefficient as 0\\%blenderFace method: video-based measurement of raw movement data during facial expressions of emotion using open-source software,"This article proposes an optical measurement of movement applied to data from video recordings of facial expressions of emotion. The approach offers a way to capture motion adapted from the film industry in which markers placed on the skin of the face can be tracked with a pattern-matching algorithm. The method records and postprocesses raw facial movement data (coordinates per frame) of distinctly placed markers and is intended for use in facial expression research (e.g., microexpressions) in laboratory settings. Due to the explicit use of specifically placed, artificial markers, the procedure offers the simultaneous measurement of several emotionally relevant markers in a (psychometrically) objective and artifact-free way, even for facial regions without natural landmarks (e.g., the cheeks). In addition, the proposed procedure is fully based on open-source software and is transparent at every step of data processing. Two worked examples demonstrate the practicability of the proposed procedure: In Study 1(N=39), the participants were instructed to show the emotions happiness, sadness, disgust, and anger, and in Study 2 (N=113), they were asked to present both a neutral face and the emotions happiness, disgust, and fear. Study 2 involved the simultaneous tracking of 14 markers for approximately 12 min per participant with a time resolution of 33 ms. The measured facial movements corresponded closely to the assumptions of established measurement instruments (EMFACS, FACSAID, Friesen \\& Ekman, 1983; Ekman \\& Hager, 2002). In addition, the measurement was found to be very precise with sub-second, sub-pixel, and sub-millimeter accuracy.",10.3758/s13428-018-1085-9
+1160,InProceedings,The Metrics to Evaluate the Health Status of OSS Projects Based on Factor Analysis,"As open-source software (OSS) development is becoming a trend, an increasing number of businesses and developers are joining OSS projects. For project managers, developers and users, understanding the current health status of a project is very important to manage a development process, select the open-source projects to development or to adopt the software packages developed by projects. Therefore, an efficient approach to evaluate the health status of the open-source project is needed. Unfortunately, although many approaches including metrics have been proposed, they are designed in arbitrary ways. In this paper, a math ematical tool, i.e., factor analysis, is used to build a health evaluation model for OSS projects. As far as we know, this is the first time that factor analysis has been applied to evaluate OSS projects. This model is based on GitHub data and uses the basic indexes that are closely related to the health status of the projects as the input. Then, six new synthetic metrics, namely community activity, project popularity, development activity, completeness, responsiveness and persistence are obtained through factor analysis, which can be used to calculate the overall health score of a project. Moreover, in order to verify the effectiveness of this model, it is applied to some real projects and the results show that the overall scores achieved by this model can reflect the health status of the projects.",10.1007/978-981-15-1377-0\\_56

This can have different meanings, according to the requested goals (rank uncertainty sources, reduce them, estimate precisely a critical threshold or an optimal working point), and it could request mathematical methods with greater or lesser complexity. This paper introduces the Uranie platform, an open-source framework developed at the Alternative Energies and Atomic Energy Commission (CEA), in the nuclear energy division, in order to deal with uncertainty propagation, surrogate models, optimisation issues, code calibration, etc. This platform benefits from both its dependencies and from personal developments, to offer an efficient data handling model, a C++ and Python interface, advanced graphi graphical tools, several parallelisation solutions, etc. These methods can then be applied to many kinds of code (considered as black boxes by Uranie) so to many fields of physics as well. In this paper, the example of thermal exchange between a plate-sheet and a fluid is introduced to show how Uranie can be used to perform a large range of analysis.",10.1051/epjn/2018050
+1162,Article,The Use of Sentinel-1 Synthetic Aperture Radar (SAR) Images and Open-Source Software for Cultural Heritage: An Example from Paphos Area in Cyprus for Mapping Landscape Changes after a 5.6 Magnitude Earthquake,"Active satellite remote sensors have emerged in the last years in the field of archaeology, providing new tools for monitoring extensive cultural heritage landscapes and areas. These active sensors, namely synthetic aperture radar (SAR) satellites, provide systematic datasets for mapping land movements triggered from earthquakes, landslides, and so on. Copernicus, the European program for monitoring the environment, provides continuous radar datasets through the Sentinel-1 mission with an almost worldwide coverage. This paper aims to demonstrate how the use of open-access and freely distributed datasets such as those under the Copernicus umbrella, along with the exploitation of open-source radar processing software, namely the sentinel applications platform (SNAP) and SNAPHU tools, provided respectively by the European Space Agency (ESA) and the University of Stanford, can be used to extract an SAR interferogram in the wider area of Paphos, located in the western part of Cyprus. The city includes various heritage sites and monuments, some of them already included in the UNESCO World Heritage list. The interferogram was prepared to study the effects of an earthquake to the buildings and sites of the area. The earthquake of a 5.6 magnitude on the Richter scale was triggered on 15 April 2015 and was strongly felt throughout the whole island. The interferogram results were based on Differential Synthetic Aperture Radar Interferometry (D-InSAR) methodology, finding a maximum uplift of 74 mm and a maximum subsidence of 31 mm. The overall process and methodology are presented in this paper.",10.3390/rs11151766

Design/methodology/approach An online survey of chief information officers, chief technology officers or heads for IT in US academic libraries was conducted. A total number of 179 responses were used for data analysis. Findings From the survey, the authors identify significant barriers and drivers that US academic libraries may consider before adopting OSS and found that awareness itself is not a barrier. While about half of respondents confirmed using OSS, the authors found surprisingly low levels of intent to adopt from current non-adopters. Practical implications - This research offers insights for promoting OSS adoption. Also, it provides funding agencies and administrators with guidelines to encourage successful deployment of OSS in higher education. Originality/value While extant research is mostly anecdotal, this research draws from an online survey to snap-shot the current state of OSS adoption in US academic libraries and provides a baseline for practice and research.",10.1108/LHT-02-2019-0042

First, this study is based on ethnographic research of free software projects and uses the resulting thick description to determine the meaning of sharing in this context. Second, the current literature on sharing usually takes user-generated content (UGC) platforms as its empirical reference, resulting in identifying a distinct meaning of sharing in this context. By combining the two sets of findings into a single narrative, this study makes three points: (1) the academic discourse on free software conceptualizing it as a form of gift-giving antithetical to the ways of capitalist production needs to be revised; (2) the use of sharing in the context of UGC platforms relies heavily on references to the culture of free software; (3) although representatives from both contexts claim to be taking part in the same sharing practices, there are substantial differences in the type of information being shared, the explicitness of the sharing mechanisms, and the organizational context of monetization of the shared objects.",10.1080/1369118X.2017.1418016
+1167,Article,To the Development of Open Source Software for the Reconstruction of CAD Models,"In this paper, we describe an open source software package aimed at solving reverse engineering problems for CAD models defined in polygonal form. We briefly discuss the main principles behind the new software, its architecture, and directions for its further development. The use of the software is illustrated by examples of a turbine blade. In the first example, the turbine blade is reconstructed automatically from a structured point cloud. Another example is the interactive reconstruction of the turbine blade from an unstructured surface triangulation. In both the cases, we use a surface skinning strategy enhanced by a curve fairing operator. We show that the modified skinning operator does not minimize the total bending energy of the surface, but yields a smooth patch where input inaccuracies are compensated for. The reconstruction result is a parametric model of the turbine blade where the design variables are the coordinates of the poles for each profile curve. The proposed software architecture can be used for partial or complete parameterization of reconstructed CAD models with the aim of their subsequent optimization.",10.1134/S036176881904008X

It can facilitate the development and solve the urgent application needs of large-scale complex software systems. To guarantee that an OSSE is stable and effective for supporting the application development, health assessment for an OSSE has become a research hotspot. In this paper, starting from a new perspective, the OSSE is compared with the ecosystem in the natural world. An OSSE health measure method is proposed by integrating projection pursuit and real-coded accelerated genetic algorithm. First, according to the snowball sampling data collection method and the grounded theory, the data is collected and processed. Second, by designing evaluation indicators and utility functions, the projection pursuit classification model of the natural ecosystem is evaluated and combined with a real-coded accelerated genetic algorithm, thereby designing the health measure model.

+1171,InProceedings,Training Software Engineers Using Open-Source Software: The Students' Perspective,"Software Engineering courses often emphasize teaching methodologies and concepts in small and controlled environments over teaching, say, maintenance aspects of full-fledged real software systems. This decision is partly justified due to the difficulty of bringing to the context of a classroom a real software project. The widespread presence of open source projects, however, is contributing to alleviating this problem. Several instructors have already adopted contributions to open source projects as part of their evaluation process, and these instructors reported many benefits, including the improvement on students' technical and social skills. However, little is known about the students' perceptions regarding the need to contribute to an open source project as part of a Software Engineering course. To better understand the students' challenges, benefits, and attitudes, we conducted 21 semi-structured interviews with students who took these courses in five different Brazilian universities. We also enriched this data with an analysis of commits performed in the repositories that students contributed to. We observed that even though some instructors chose the open source projects to students to work themselves, some students and even the open source community participated in the process of choosing projects and tasks. Students' contributions varied concerning both complexity (measured by the number of additions, deletions, and edited files) and diversity (measured regarding the different programming languages used). Among the benefits, students reported improving their technical skills and their self-confidence. Finally, some students found extremely important for instructors' being involved with open source initiatives (extra-classroom).",10.1109/ICSE-SEET.2019.00024

The aim of the study was to develop, describe and evaluate an online VO2 fitting tool (VO(2)FITTING) for dynamically editing, processing, filtering and modelling VO2 responses to exercise. VO(2)FITTING was developed in Shiny, a web application framework for R language. Validation VO2 datasets with both noisy and non-noisy data were developed and applied to widely-used models (n = 7) for describing different intensity transitions to verify concurrent validity. Subsequently, we then conducted an experiment with age-group swimmers as an example, illustrating how VO(2)FITTING can be used to model VO2 kinetics. Perfect fits were observed, and parameter estimates perfectly matched the known inputted values for all available models (standard error = 0; p < 0.001).

A Case of Bug Finding Research,"In recent years, many researchers in the SE community have been devoting considerable efforts to provide FLOSS developers with a means to quickly find and fix various kinds of bugs in FLOSS products such as security and performance bugs. However, it is not exactly sure how FLOSS developers think about bugs to be removed preferentially. Without a full understanding of FLOSS developers' perceptions of bug finding and fixing, researchers' efforts might remain far away from FLOSS developers' needs. In this study, we interview 322 notable GitHub developers about high impact bugs to understand FLOSS developers' needs for bug finding and fixing, and we manually inspect and classify developers' answers (bugs) by symptoms and root causes of bugs. As a result, we show that security and breakage bugs are highly crucial for FLOSS developers. We also identify what kinds of high impact bugs should be studied newly by the SE community to help FLOSS developers.",10.1007/978-3-030-20883-7\\_5

It has been reported that less than 10\\% of Open Source Software (OSS) contributors in GitHub are women. Although related qualitative and quantitative studies point out the gender gap, the technical and social interaction of females within OSS still remain unexplored and largely misunderstood. As a first step towards proposing articulated actions towards diversity and inclusion, we need first to explore the gender gap in terms of activities and interactions. Thus, we propose to answer the questions: where are females in OSS projects? How they evolve? and How they contribute to the sustainability of the OSS social capital?. We particularly focus on building socio-technical networks and analyze them to explain how females contribute and interact in practice. We reflect on interactions' graphs and examine through a preliminary study, using data from six OSS projects, possible links between existing findings and the directions we suggest for more gender diversity. We found that females are extremely underrepresented within OSS communities, but when they participate they are productive just as males, they evolve following relatively the same patterns than males and remain more involved in projects than males.",10.1007/978-3-030-28464-0\\_27

The goal of this work is to identify the current motivations for adopting open source software, and compare them with the motivations that held in the past. We conducted a set of interviews among software practitioners, asking them to rank motivations for the adoption of open source software, and we compared these new results with the motivations elicited in previous surveys published in 2010 and 2013.

Using the concept of episodic volunteering (EV) from the general volunteering literature, we derive a model consisting of five key constructs that we hypothesize affect episodic volunteers' retention in FLOSS communities. To evaluate the model we conducted a survey with over 100 FLOSS episodic volunteers. We observe that three of our model constructs (social norms, satisfaction and community commitment) are all positively associated with volunteers' intention to remain, while the two other constructs (psychological sense of community and contributor benefit motivations) are not. Furthermore, exploratory clustering on unobserved heterogeneity suggests that there are four distinct categories of volunteers: satisfied, classic, social and obligated. Based on our findings, we offer suggestions for projects to incorporate and manage episodic volunteers, so as to better leverage this type of contributors and potentially improve projects' sustainability.",10.1109/ICSE.2019.00100

The overall success of peer code review, commonly used in open source projects, has likely contributed strongly to this success. Code review is an emotionally loaded practice, with public exposure of reputation and ample opportunities for conflict. We set off to ask why code review works for open source communities, despite this inherent challenge. We interviewed 21 open source contributors from four communities and participated in meetings of ROS community devoted to implementation of the code review process. It appears that the hacker ethic is a key reason behind the success of code review in FOSS communities. It is built around the ethic of passion and the ethic of caring. Furthermore, we observed that tasks of code review are performed with strong intrinsic motivation, supported by many non-material extrinsic motivation mechanisms, such as desire to learn, to grow reputation, or to improve one's positioning on the job market. In the paper, we describe the study design, analyze the collected data and formulate 20 proposals for how what we know about hacker ethics and human and social aspects of code review, could be exploited to improve the effectiveness of the practice in software projects.",10.1109/ICSE.2019.00111

However, the stages when developers leave the projects are still weakly explored and are not well-defined in existing developers' lifecycle models. In this position paper, we enrich the knowledge about the leaving stage by identifying sleeping and dead states, representing temporary and permanent brakes that developers take from contributing.

Although there are several open-source BN learners in the public domain, none of them are able to handle both small and large feature space data and recover network structures with acceptable accuracy. bAIcis (R) is a novel BN learning and simulation software from BERG. It was developed with the goal of learning BNs from ``Big Data{''} in health care, often exceeding hundreds of thousands features when research is conducted in genomics or multi-omics. This article provides a comprehensive performance evaluation of bAIcis and its comparison with the open-source BN learners. The study investigated synthetic datasets of discrete, continuous, and mixed data in small and large feature space, respectively. The results demonstrated that bAIcis outperformed the publicly available algorithms in structure recovery precision in almost all of the evaluated settings, achieving the true positive rates of 0.9 and precision of 0.8.

Studies in estimating maintenance effort (MEE) of such software product have been published in the literature in order to provide better estimation. The aim of this study is to provide a review of studies related to maintenance effort estimation for open source software (OSSMEE). To this end, a set of 60 primary empirical studies are selected from six electronic databases and a discussion is provided according to eight research questions (RQs) related to: publication year, publication source, datasets (OSS projects), metrics (independent variables), techniques, maintenance effort (dependent variable), validation methods, and accuracy criteria used in the empirical validation. This study has found that popular OSS projects have been used, Linear Regression, Na\\""{\\i}ve Bayes and k Nearest Neighbors were frequently used, and bug resolution was the most used regarding the estimation of maintenance effort for the future releases.

Based on longitudinal data collected from the comprehensive R archive network (CRAN), we empirically examine how the network of R packages evolves over time and exert its influence on the scientific community. We find that critical network features derived from CRAN, such as page-rank, closeness, and betweenness centralities, play a significant role in determining the impact of each package on the research and publication activities in the scientific community. Furthermore, the performance of R packages can be explained as a flow of information from the core to the periphery that exhibits strong spillover effects.",NA
+1205,InProceedings,A Survey of Learning Methods in Open Source Software,"Open source software (OSS) is usually developed by heterogeneous groups of people, each with their own interests, motivations and abilities. Therefore, it is important to establish the best software development and contributing practices early in the life-time of the project. Such practices should foster the contributors' involvement in the OSS project as quickly as possible. The sustainability of an OSS project is heavily based on the underlying community of contributors and on the knowledge and skills they bring to the project and they acquire and develop through their participation in the project and interaction with the project community. Therefore, identifying and investigating contributors' learning processes is an important research area in OSS. This survey paper presents an overview of open source learning methods in order to explore how community interaction impacts the development and application of OSS learning processes in other areas, especially in education. It is argued that collaboration with peers and consistent code contributions result in learning progress in OSS. Typical research in this area is based on case by case analysis, whereas this survey tries to highlight and combine the outcomes of several research contributions from the literature.",10.1007/978-3-030-54997-8\\_10

Although many data scientists and the high-performing companies that employ them seem to have developed robust methods to employ data sciences practices to achieve competitive advantages, there have been few attempts at defining and explaining how and why data science helps firms to achieve desired outcomes. In this paper, we describe how data science, which combines computer programming, domain knowledge, and analytic skillsets to scientifically extract insights from data, can be used to help meet the growing demand of analytic needs across an organization's value chain. This is done through the illustration of an applied data science initiative to a strategic sourcing problem via the use of open-source technology. In doing so, we contribute to the growing data science literature by demonstrating the application of unique data science capabilities. Moreover, the paper provides a tutorial on how to use a specific R package along with an actual case in which that package use used.",10.1016/j.ijinfomgt.2020.102167

In both academic and industry data analytics, open-source software (OSS) has gained massive popularity. Collaborative source code allows students to interact with researchers, code developers, and users from a variety of disciplines. Based on the authors' experiences as graduate students and coding instructors, this paper provides a unique overview of the obstacles that graduate students face in obtaining the knowledge and skills required to complete their research and in transitioning from an OSS user to a contributor: psychological, practical, and cultural barriers and challenges specific to graduate students including cognitive load in graduate school, the importance of a knowledgeable mentor, seeking help from both the online and local communities, and the ongoing campaign to recognize software as research output in career and degree progression. Specific and practical steps are recommended to provide a foundation for graduate students, supervisors, administrators, and members of the OSS community to help overcome these obstacles. In conclusion, the objective of these recommendations is to describe a possible framework that individuals from across the scientific community can adapt to their needs and facilitate a sustainable feedback loop between graduate students and OSS.",10.1139/facets-2019-0020

OSS projects are collaborative endeavours which have multiple contributors who are constantly joining, leaving, or changing their role in the project. This ever-changing and ever-transient nature of OSS project contributors contributes to a contributor turnover-induced knowledge loss in OSS projects. In this case, ``knowledge loss{''} refers to the phenomenon of the loss of project-specific knowledge, experience, and expertise in an OSS project, caused by contributors regularly joining and leaving the OSS project. This paper describes the design and development of a robust research methodology and contributes towards the formation of proactive knowledge retention practices in OSS projects to transform contributor's use of knowledge and engagement in knowledge-relevant activities including knowledge sharing and knowledge transfer.",10.1002/smr.2198
+1213,Article,A method for analyzing stakeholders' influence on an open source software ecosystem's requirements engineering process,"For a firm in an open source software (OSS) ecosystem, the requirements engineering (RE) process is rather multifaceted. Apart from its typical RE process, there is a competing process, external to the firm and inherent to the firm's ecosystem. When trying to impose an agenda in competition with other firms, and aiming to align internal product planning with the ecosystem's RE process, firms need to consider who and how influential the other stakeholders are, and what their agendas are. The aim of the presented research is to help firms identify and analyze stakeholders in OSS ecosystems, in terms of their influence and interactions, to create awareness of their agendas, their collaborators, and how they invest their resources. To arrive at a solution artifact, we applied a design science research approach where we base artifact design on the literature and earlier work. A stakeholder influence analysis (SIA) method is proposed and demonstrated in terms of applicability and utility through a case study on the Apache Hadoop OSS ecosystem. SIA uses social network constructs to measure the stakeholders' influence and interactions and considers the special characteristics of OSS RE to help firms structure their stakeholder analysis processes in relation to an OSS ecosystem. SIA adds a strategic aspect to the stakeholder analysis process by addressing the concepts of influence and interactions, which are important to consider while acting in collaborative and meritocratic RE cultures of OSS ecosystems.",10.1007/s00766-019-00310-3

Open Source Software (OSS) projects have been an alternative to support education in Software Engineering, as they allow contact with real development projects and environments. However, the adoption of these projects in the classroom presents some obstacles, such as choosing the appropriate project, and the time and effort needed to prepare the classes and get used to the open source environment. In order to reduce the difficulties faced by instructors, we are working on developing a portal to catalog worked examples extracted from OSS projects to assist instructors. In this paper, we present the first steps towards creating this catalog, which is creating a pattern for guiding the structuring the worked examples. We are applying the Design Science Research paradigm. The activities reported in this paper regards the first Design Cycle, and were divided into three stages related to the elaboration and evaluation of the pattern for cataloging the worked examples. In these stages, we carried out focus groups and interviews with Software Engineering instructors, including the instantiation of the pattern to catalog actual worked examples. After each stage, we had a new and improved version of the pattern for cataloging the worked examples. Such pattern served as a basis to create the first version of the worked examples portal, which will be evaluated in the next stages of the research.",10.1145/3422392.3422471

However, it cannot be applied in the open source (FOSS) communities, without adaptation to their particularities, especially to the specific control mechanisms developed in FOSS. FOSS communities are self-managed, and rely on consensus to reach decisions. This study proposes a PAR framework specifically tailored to FOSS communities. We successfully applied the framework to implement a set of quality assurance interventions in the Robot Operating System community. The framework we proposed is composed of three components, interventions design, democratization, and execution. We believe that this process will work for other FOSS communities too. We have learned that changing a particular aspect of a FOSS community is arduous. To achieve success the change must rally the community around it for support and attract motivated volunteers to implement the interventions.",10.1007/s10664-020-09849-0
+1218,Article,A tutorial and open source software for the efficient evaluation of gravity and magnetic kernels,"Fast computation of three-dimensional gravity and magnetic forward models is considered. When the measurement data is assumed to be obtained on a uniform grid which is staggered with respect to the discretization of the parameter volume, the resulting kernel sensitivity matrices exhibit block-Toeplitz-Toeplitzblock (BTTB) structure. These matrices are symmetric for the gravity problem but unsymmetric for the magnetic problem. In each case, the structure facilitates fast forward computation using two-dimensional fast Fourier transforms. The construction of the kernel matrices and the application of the transform for fast forward multiplication, for each problem, is carefully described. But, for purposes of comparison with the non-transform approach, the generation of the unique entries that define a given kernel matrix is also explained. It is also demonstrated how the matrices, and hence transforms, are adjusted when padding around the volume domain is introduced. The transform algorithms for fast forward matrix multiplication with the sensitivity matrix and its transpose, without the direct construction of the relevant matrices, are presented. Numerical experiments demonstrate the significant reduction in computation time and memory requirements that are achieved using the transform implementation. Thus, it becomes feasible, both in terms of reduced memory requirements and computational time, to implement the transform algorithms for large three-dimensional volumes. All presented algorithms, including with variable padding, are coded for optimal memory, storage and computation as an open source MATLAB code which can be adapted for any convolution kernel which generates a BTTB matrix, whether or not it is symmetric. This work, therefore, provides a general tool for the efficient simulation of gravity and magnetic field data, as well as any formulation which admits a sensitivity matrix with the required structure.",10.1016/j.cageo.2020.104575
+1219,Article,A universal cross language software similarity detector for open source software categorization,"While there are novel approaches for detecting and categorizing similar software applications, previous research focused on detecting similarity in applications written in the same programming language and not on detecting similarity in applications written in different programming languages. Cross-language software similarity detection is inherently more challenging due to variations in language, application structures, support libraries used, and naming conventions. In this paper we propose a novel model, CroLSim, to detect similar software applications across different programming languages. We define a semantic relationship among cross-language libraries and API methods (both local and third party) using functional descriptions and a word-vector learning model. Our experiments show that CroLSim can successfully detect cross-language similar software applications, which outperforms all existing approaches (mean average precision rate of 0.65, confidence rate of 3.6, and 75\\% highly rated successful queries). Furthermore, we applied CroLSim to a source code repository to see whether our model can recommend cross-language source code fragments if queried directly with source code. From our experiments we found that CroLSim can recommend cross-language functional similar source code when source code is directly used as a query (average precision=0.28, recall=0.85, and F-Measure=0.40).

The explosion of the World Wide Web, dynamic nature of information technologies, like open source; and with escalation of electronics resources showed the way of Automated Library System (ALS). These changes are replicated in the conceptual differences between the ALS and the Integrated Library System (ILS). The ALS is acknowledged as simply a database to house and retrieve a library's holdings while ILS is acknowledged as robust clusters of systems including every process and module linked to library processes. This article presents an aspect on the evolving features of some commonly adopted Open-Source ILS Software (Koha, NewGenLib, and Evergreen) which had encouraged ALS to ILS, as well as justifications and barriers to the use of open source. Open source library management software is a solution to reducing that cost. The research describes in brief about the feature of some of the open source digital library software like Greenstone, DSpace E-Prints and integrated library software Koha NewGenlib. Evergreen ILS etc., which are useful for developing ILS and institutional repositories software in academic libraries.

OSS communities do not generally know how to apply usability techniques and are unclear about which techniques to use in each activity of the development process. The aim of our research is to adopt the HTA usability technique in the OpenOffice Writer OSS project and determine the feasibility of adapting the technique for application. To do this, we participated as volunteers in the project. We used the case study research method during technique application and participation in the community. As a result, we identified adverse conditions that were an obstacle to technique application and modified the technique to make it applicable to OSS projects. We can conclude from our experience that these changes were helpful for applying the technique, using web artifacts like forums and collaborative tools like Cacoo, although it was not easy to recruit OSS users to participate in usability technique application.",10.1007/978-3-030-60114-0_13

Analyzing the behaviors of contributors helps us understand the development process of open source software and explore the general and special rules of it. Agent based model is a type of computing model that can simulate the behaviors and interactions between autonomous entities. With agent based models, we can simulate the self-organization process of open source software development by simulating contributors' behaviors. Therefore, we design an agent-based simulation system for open source software development, which are implemented with the Java Agent Development framework. In experiments, we obtain the simulation results by inputting historical behavior information of open source repositories on GitHub. Then we compare the results of various models. Finally, by adjusting input parameters for issue resolution process, we analyze the impact of these parameters, which shows this system also helps understand how to control the open source software development process.",10.1109/SERVICES48979.2020.00044
+1224,InProceedings,An Empirical Study on the Persistence of SpotBugs Issues in Open-Source Software Evolution,"Background. Static analyzers can be useful to software developers in detecting and locating code issues and, in addition, classifying their nature. The main problem of static analyzers, however, is that they may signal too many false alarms. Objective. In this paper, we investigate whether code issues that are detected by SpotBugs persist in software code, or if they get removed. We chose SpotBugs because it is one of the best-known and most used static analyzers. Method. We carried out an empirical study on five open-source Java programs and took into account two versions of each of them, to check whether the issues signaled by SpotBugs on the older version had been removed by the time the newer version was released. A total of 1,006 issues were signaled by SpotBugs. Results. Our results show that about half of the issues signaled disappeared between the two versions, but the correction rate was uneven across projects. Issues about the correctness of software code were more likely to be no longer present in the newer version than other types of warnings. Conclusions. Further investigations are required, to understand why some projects appear more active than others in correcting SpotBugs issues, and why very few high-severity warnings were observed in the analyzed code. Nonetheless, the fact that about half of the issues flagged by SpotBugs were removed indicates that the tool is effective in detecting incorrect or otherwise problematic code.",10.1007/978-3-030-58793-2\\_12
+1225,InProceedings,An Exploratory Study on Developers Opinions about Influence in Open Source Software Ecosystems,"Software Engineering researchers and practitioners have sought a systematic way of characterizing technical and social behaviors in software development, from the perspective of either an artifact (e.g. design pattern) or an actor (e.g. developer). In this context, influencers are those who guide the development methods and disseminate patterns due to their popularity or status in the community. Especially in software ecosystems, the dynamics of interactions with interventions of external developers over a common technological platform leverage the effects of influence and still remains as a challenge. This paper presents an exploratory study on the sense of influence in open source software ecosystems, more specifically from the opinions of 95 developers who contribute to npm projects based on GitHub. To do so, qualitative data from a conducted survey research were analyzed based on Grounded Theory ( GT) procedures. Based on two main categories (Technical and Social), we recognized aspects that reinforce some key characteristics of an influencer, e.g., `status in the project', `participation with code', `participation with comments', and `content value'. However, some diverging aspects were observed, e.g., the difference between qualitative and quantitative responses related to `long-time interaction with the project'. This study contributes with the identification of influencers' characteristics that can aid both researchers in further studies on open source software ecosystems and practitioners in strategies to manage project-based ecosystems.",10.1145/3422392.3422404
+1227,InProceedings,An Exploratory Study on Extract Method Floss-Refactoring,"As a software evolves its code requires constant updating. In this sense, refactoring edits aim at improving structural aspects of a code without changing its external behavior. However, studies show that developers tend to combine in a single commit refactorings and behavior-changing edits (extra edits) - floss-refactoring. Floss-refactorings can be error-prone and require careful handling. However, little has been done to understand how refactorings and extra edits relate in practice. In this work, we propose a strategy for extracting floss-refactoring data. Moreover, we mine code repositories of 16 open-source projects and analyse commits with floss refactoring related to Extract Method. Our results show that developers often combine Extract Method with inner method extra edits (e.g., statement insert), with an expected increase of 8-16\\% of extra edits by each Extract Method. Moreover, some statements are more likely to be changed depending on the extra edit performed.",10.1145/3341105.3373893

Traditionally, research on OSS security has often focused on technical aspects of software development. We argue that these aspects are important, however, technical security practice considering different social aspects of OSS development will assure the effectiveness and efficiency of the implementation of the tool. To mitigate this research gap, in this empirical study, we explore the current security culture in the OSS development phenomenon using a survey instrument with six evaluation dimensions: attitude, behavior, competency, subjective norms, governance, and communication. By exploring the current security culture in OSS communities, we can start to understand the influence of security on participants' security behaviors and decision-making, so that we can make realistic and practical suggestions. In this paper, we present the measurements of security culture adopted in the study and discuss corresponding security issues that need to be addressed in OSS communities.",10.1145/3341161.3343520
+1230,Article,An open-source software for monitoring intrafraction motion during external beam radiation therapy based on superimposition of contours of projected ROIs on cine-MV images,"Purpose To present an open-source software () for monitoring intrafraction motion that is based on the visualization of superimposed contours of projected region-of-interests from DICOM RTSTRUCT files on cine-MV images acquired and displayed in real-time during radiation therapy delivery. Clinical use with prostate gold fiducial markers is presented. Methods Projections of regions of interest (ROI) in the reference frame of the electronic portal imaging device are computed offline for different gantry angles before the first treatment fraction. During treatment delivery, the contrast of portal images is automatically adjusted using a histogram equalization algorithm. The projections associated with the current gantry angle are then superimposed on the images in real time. This allows the therapist to evaluate if the imaged structures of interest remain within their respective contours during treatment delivery and to potentially interrupt the treatment if deemed necessary. The spatial accuracy of the method was evaluated by imaging a ball bearing phantom in a set-up where the position of the projected ROI is highly sensitive to gantry angle errors. The visibility of fiducial markers during one fraction of seven different volumetric modulated arc therapy (VMAT) prostate treatments is characterized. Results The geometric validation showed a negligible systematic error mu < 0.1 mm for the position of the projections. The random errors associated with the time accuracy of the gantry angle readout were characterized by standard deviations sigma <= 0.6 mm. The VMAT clinical treatments showed that the fiducial markers were frequently visible, allowing for a meaningful clinical use. Conclusions The results demonstrate that the method presented is sufficiently accurate to be used for intrafraction monitoring of patients. The fact that this method could be implemented on many modern linacs at little to no cost and with no additional dose delivered to the patients makes this solution very attractive for improving patient care and safety in radiation therapy.",10.1002/acm2.12940

These elements are coupled with each other with some kind of dependency relationships to some degree, and their interactions naturally form a graph or network structure. In this study, we generated the static function-call graphs of several open-source software systems, where functions were the most basic type of interacting elements calling each other. Then, we analyzed the call graphs both visually and topologically using the techniques of complex network analysis. We found the call graphs to reveal scale-free and small-world network properties similar to the findings of the previous studies. In addition, we identified the most central and important functions in each call-graph using several centrality measures. We also performed community analysis and found that the call graphs exhibited a tendency to form communities.

With the growth of Free and Open Source Software (FOSS), network automation software solutions also started to adhere to this development model. However, as it is known from the literature, onboarding to FOSS projects is not a trivial task and may be more challenging for people without a software development background. In this paper, we study network automation FOSS projects, which are seeing a large number of new contributors who do not have traditional software engineering skills. We analyze a set of data collected from pull requests and issues collected from 81 GitHub projects (71 network automation projects, and 10 top-projects from other domains), to identify the characteristics that are specific to first-time project contributors in the network automation domain.

To alleviate this problem, we propose an approach to automatically generate repository tag based on a neural network and LDA by utilizing package dependencies and readme among OSS in communities. We design an algorithm for extracting the tag features of dependent OSS packages and build dependent feature vectors for OSS. We then combine the vectors with topic of OSS readme file as input to train the neural network and obtain the tag distribution probability of OSS, and subsequently, recommend tags for OSS.

+1240,Article,BioPETsurv: Methodology and open source software to evaluate biomarkers for prognostic enrichment of time-to-event clinical trials,"Biomarkers can be used to enrich a clinical trial for patients at higher risk for an outcome, a strategy termed ``prognostic enrichment.{''} Methodology is needed to evaluate biomarkers for prognostic enrichment of trials with time-to-event endpoints such as survival. Key considerations when considering prognostic enrichment include: clinical trial sample size; the number of patients one must screen to enroll the trial; and total patient screening costs and total per-patient trial costs. The Biomarker Prognostic Enrichment Tool for Survival Outcomes (BioPETsurv) is a suite of methods for estimating these elements to evaluate a prognostic enrichment biomarker and/or plan a prognostically enriched clinical trial with a time-to-event primary endpoint. BioPETsurv allows investigators to analyze data on a candidate biomarker and potentially censored survival times. Alternatively, BioPETsurv can simulate data to match a particular clinical setting. BioPETsurv's data simulator enables investigators to explore the potential utility of a prognostic enrichment biomarker for their clinical setting. Results demonstrate that both modestly prognostic and strongly prognostic biomarkers can improve trial metrics such as reducing sample size or trial costs. In addition to the quantitative analysis provided by BioPETsurv, investigators should consider the generalizability of trial results and evaluate the ethics of trial eligibility criteria. BioPETsurv is freely available as a package for theRstatistical computing platform, and as a webtool at www.prognosticenrichment.com/surv.",10.1371/journal.pone.0239486
+1241,Article,Brain Modeling ToolKit: An open source software suite for multiscale modeling of brain circuits,"Experimental studies in neuroscience are producing data at a rapidly increasing rate, providing exciting opportunities and formidable challenges to existing theoretical and modeling approaches. To turn massive datasets into predictive quantitative frameworks, the field needs software solutions for systematic integration of data into realistic, multiscale models. Here we describe the Brain Modeling ToolKit (BMTK), a software suite for building models and performing simulations at multiple levels of resolution, from biophysically detailed multi-compartmental, to point-neuron, to population-statistical approaches. Leveraging the SONATA file format and existing software such as NEURON, NEST, and others, BMTK offers a consistent user experience across multiple levels of resolution. It permits highly sophisticated simulations to be set up with little coding required, thus lowering entry barriers to new users. We illustrate successful applications of BMTK to large-scale simulations of a cortical area. BMTK is an open-source package provided as a resource supporting modeling-based discovery in the community.",10.1371/journal.pcbi.1008386

+1244,Article,Chipper: Open-source software for semi-automated segmentation and analysis of birdsong and other natural sounds,"Audio recording devices have changed significantly over the last 50 years, making large datasets of recordings of natural sounds, such as birdsong, easier to obtain. This increase in digital recordings necessitates an increase in high-throughput methods of analysis for researchers. Specifically, there is a need in the community for open-source methods that are tailored to recordings of varying qualities and from multiple species collected in nature. We developed Chipper, a Python-based software to semi-automate both the segmentation of acoustic signals and the subsequent analysis of their frequencies and durations. For avian recordings, we provide widgets to best determine appropriate thresholds for noise and syllable similarity, which aid in calculating note measurements and determining song syntax. In addition, we generated a set of synthetic songs with various levels of background noise to test Chipper's accuracy, repeatability and reproducibility. Chipper provides an effective way to quickly generate quantitative, reproducible measures of birdsong. The cross-platform graphical user interface allows the user to adjust parameters and visualize the resulting spectrogram and signal segmentation, providing a simplified method for analysing field recordings. Chipper streamlines the processing of audio recordings with multiple user-friendly tools and is optimized for multiple species and varying recording qualities. Ultimately, Chipper supports the use of citizen-science data and increases the feasibility of large-scale multi-species birdsong studies.",10.1111/2041-210X.13368
+1245,InProceedings,Comparative Assessment of the Unsupervised Land Use Classification by Using Proprietary GIS and Open Source Software,"Mapping and investigating land use land cover (LULC) changes over a particular region is crucial for resource management, sustainability development, and holistic planning. An increasing rate of urban growth and urban sprawl could induce changes in land use as well as land transformation. However, accurate and up-to-date information about LULC is required for providing better understanding and assessing the environmental consequences of such changes. In this study, the 2017 image from the Sentinel-2A Satellite was utilized to demonstrate the land cover classification analysis in Iskandar Malaysia. Usually, land use classification analysis is conducted through proprietary GIS software. However, this decade shows the advancement in software development, thus the emerging of free/open source software in the geospatial world. Hence, to execute land cover analysis using the Unsupervised Classification technique, the proprietary GIS software (ArcGIS) and free/open source software (QGIS) were deployed. Then, the examination of accuracy assessment was carried out for the selected software. The sum of 250 random points was established for the assessment purpose. The results showed the overall accuracy for ArcGIS and QGIS were 82.80\\% and 80.40\\% respectively. The kappa coefficient for ArcGIS was 0.7395, while kappa coefficient for QGIS was 0.7094. Besides that, ArcGIS demonstrated better producer's accuracy in the forest and agriculture land covers classification. Meanwhile, QGIS exhibited better producer's accuracy in the built-up and water features classification. To summarize, ArcGIS and QGIS software are reliable to be used in the land cover classification.",10.1088/1755-1315/540/1/012020

The focus is on social class, attitudes towards unions and professional bodies and participation in the broader ICT community - specifically Free, Libre and Open Source Software (FLOSS). The findings reveal absence of formal collective frames of reference or organization, yet the creativity, autonomy and initiative central to the identity of ICT workers may offer opportunities for collectivization particularly with regard to participation in FLOSS communities.",10.1177/0143831X17695441

We lack knowledge regarding the microprocesses companies deliberately introduce to manage knowledge sharing with such outside parties. We research these processes in the context of collaboration between companies and open source software (OSS) communities by posing the question: How do companies design explicit mechanisms to manage knowledge exchange with OSS communities? We conduct an explorative case study at Siemens AG. Siemens introduced a formal template process which can be adapted by the organizational units according to their demands. Results show that the extent to which the process is implemented depends on the level of closeness to core intellectual property of the organizational unit and the intensity of the involvement in OSS communities. Developers use several methods to shortcut the process. Our study contributes to the literature on organizational knowledge sharing, company-involved OSS development, and open innovation of firms.",NA

Following the original study, we analyze project development data, archived in the GitHub repository, for the OSS project Rubinius. The analysis explores relationships among development and developer interdependencies as well as activity and order variation. Further, we extend the original study by examining the core relationships in the original study and investigating the external generalizability of the results by replicating the analysis on three analogous OSS projects: JRuby, mruby, and RubyMotion. These offer an opportunity to evaluate the generalizability of the original study to projects of different sizes and amount of activity, yet similar otherwise to the project in the original study. Another extension is the use of an additional control variable, length of activity sequence, which proves to have substantial implications of the study’s focal relationships. We find that three out of the four projects we analyze support the findings of the original study as it pertains to four relationships in the original study: order variation and developer interdependencies, activity variation and developer interdependencies, order variation and development interdependencies, and development and developer interdependencies. We also discuss the implications of our findings, especially in cases where the replication results differ from those in the original study and offer suggestions for future research that can help advance this stream of research.",10.17705/1atrr.00057

These techniques make it possible to study internal features by non-destructive analysis. Despite its potential, the development of 3D imaging in the Geosciences is behind other fields due to the high cost of commercial software and the scarce free alternatives. Most free software was designed for the Health Sciences, and the pre-settled workflows are not suited to geoscientific materials. Thus, an outstanding challenge in the Geosciences is to define workflows using free alternatives for Computed Tomography (CT) data processing, promoting data sharing, reproducibility, and the development of specific extensions. We present CroSSED, a processing sequence for 3D reconstructions of CT data, using 3DSlicer, a popular application in medical imaging. Its usefulness is exemplified in the study of burrows that have low-density contrast with respect to the host sediment. For geoscientists who have access to CT data and wish to reconstruct 3D structures, this method offers a wide range of possibilities and contributes to open-science and applied CT studies.",10.1038/s41597-020-00614-y
+1253,Article,Decision-making Processes in Community-based Free/Libre Open Source Software-development Teams with Internal Governance: An Extension to Decision-making Theory,"Community-based free/libre open source software (FLOSS) teams with internal governance constitute an extreme example of distributed teams, prominent in software development. At the core of distributed team success lies team decision making and execution. However, in FLOSS teams, one might expect the lack of formal organizational structures to guide practices and reliance on asynchronous communication to make decision making problematic. Despite these challenges, many effective FLOSS teams exist. We lack research on how organizations make IS development decisions in general and on FLOSS decision-making models in particular. The decision-making literature on FLOSS teams has focused on the distribution of decision-making power. Therefore, it remains unclear which decision-making theories fit the FLOSS context best or whether we require novel decision-making models. We adopted a process-based perspective to analyze decision making in five community-based FLOSS teams. We identified five different decision-making processes, which indicates that FLOSS teams use multiple processes when making decisions. Decision-making behaviors remained stable across projects even though they required different types of knowledge. We help fill the literature gap about which FLOSS decision mechanisms one can explain using classical decision-making theories. Practically, community and company leaders can use knowledge of these decision processes to develop infrastructure that fits FLOSS decision-making processes.",10.17705/1CAIS.04620
+1257,Article,Determination of thermodynamic acidity constants and limiting ionic mobilities of weak electrolytes by capillary electrophoresis using a new free software AnglerFish,"Thermodynamic acidity constants (acid or acid-base dissociation constants, sometimes called also as ionization constants) and limiting ionic mobilities (both of them at defined temperature, usually 25 degrees C) are the fundamental physicochemical characteristics of a weak electrolyte, that is, weak acid or weak base or ampholyte. We introduce a novel method for determining the data of a weak electrolyte by the nonlinear regression of effective electrophoretic mobility versus buffer composition dependence when measured in a set of BGEs with various pH. To correct the experimental data for zero ionic strength we use the extended Debye-Huckel model and Onsager-Fuoss law with no simplifications. Contrary to contemporary approaches, the nonlinear regression is performed on limiting mobility data calculated by PeakMaster's correction engine, not on the raw experimental mobility data. Therefore, there is no requirement to perform all measurements at a constant ionic strength of the set of BGEs. We devised the computer program AnglerFish that performs the necessary calculations in a user-friendly fashion. All thermodynamic pKa values and limiting electrophoretic mobilities for arbitrarily charged substances having any number of ionic forms are calculated by one fit. The user input consists of the buffer composition of the set of BGEs and experimentally measured effective mobilities of the inspected weak electrolyte.",10.1002/elps.201900283
+1258,Article,Developing a spectral pipeline using open source software and low-cost hardware for material identification,"The ability to access, design and create low cost sensors capable of returning scientifically useful data has led to an exponential increase in citizen science, education and environmental monitoring groups. Low-cost spectroscopy is one such application and mobile phone camera-based instruments have been used in pollution monitoring, medical applications in developing countries and vegetation analysis. Can such an instrument be developed and tested to assist with automated detection of materials, possibly from space? We tested two spectrometer designs inside a two unit (2U) cubesat frame against a series of materials exhibiting phenomenology in the visible/near infrared (Vis/NIR) portion of the spectrum and vegetation groups. This was conducted in order to determine whether open source designs were capable of discriminating against similar materials, such as types of vegetation or types of iron-rich minerals. A spectral pipeline was created using open source programming software that was capable of converting raw sensor data into spectra, comparing samples of interest against a spectral library and returning an identification result with a confidence interval. We found that low-cost hardware sensitive to NIR and freely available software were able to identify types of materials in the study set, enabling applications in citizen science, education and outreach or even low-cost near-space research.",10.1080/01431161.2019.1693075

+1261,Article,Digital Transformation and Governance Innovation for Public Biobanks and Free/Libre Open Source Software Using a Blockchain Technology,"Digitalization and digital health are transforming research practices, while economic growth is increasingly driven by the information commons. In the case of biological sciences, information commons, such as public biobanks and free/libre open source software (FLOSS), are of paramount importance for both research and the bioeconomy. In a time of digitalization, however, information commons are vulnerable to violations, such as the free-rider problem, that render the commons unsustainable. Consequently, it has been argued that the enclosure of the informational common resources is the only means to effectively exploit them. Given the social and economic importance of the information commons, the new digital environment in biology and health requires governance innovation that will regulate the social embedding of the commons and their relationship to the free market, that is, a new political economy is needed. In this context, the need for a core common infrastructure, stretching from the physical to the logical and content layer of the information environment, that will guarantee the protection of the commons from both violations and enclosures, has been highlighted. Focusing on the interaction between two biological/bioinformatics commons, namely public biobanks and the FLOSS, we have set up an ecosystem relying on a blockchain technology. The proposed governance mechanism protects the information commons from the free-rider problem and guarantees their sustainability without hampering their operational framework. Our model demonstrates the interdependence and protection of the information commons not as an abstract theoretical exercise, but rather as a physical reality on the digital ontological matrix.",10.1089/omi.2019.0178

+1266,Article,Early healing of alveolar bone promoted by microRNA-21-loaded nanoparticles combined with Bio-Oss particles,"Features of rapid loss and inadequate bone mass of alveolar bone after teeth extraction are still great obstacles for a successful subsequential dental implantation. MicroRNA-based therapy, though an advantageous strategy in tissue regeneration, is still not available for alveolar bone due to the unique complicated oral environment which is full of enzymes and electrolytes. In this paper, a microRNA-activated scaffold constituted of microRNA21 nanoparticles combined with porous Bio-Oss particles was designed for the use of accelerating the early stage healing of the alveolar bone. It was noteworthy that the regeneration of alveolar bone was rapidly promoted to be shortened from the ordinary 3 months to 2 weeks. The nanoparticles designed by us according to the oral environment could protect microRNA from various enzymes and electrolytes attack, leading to a steady, continuous, and efficient delivery of gene. With the aid of porous Bio-Oss, microRNA-21 released in situ and its effects on highly reducing the recovery time and improving the quality of newly formed bone at the alveolar site were confirmed for the first time. Great potential could be seen for the microRNA-mediated biofunctionalized scaffold on the future dental application.",10.1016/j.cej.2020.126026

However, as with any new technology adoption, bots may impact group dynamics. Since understanding and anticipating such effects is important for planning and management, we investigate how several activity indicators change after the adoption of a code review bot. We employed a regression discontinuity design on 1,194 software projects from GitHub. Our results indicate that the adoption of code review bots increases the number of monthly merged pull requests, decreases monthly non-merged pull requests, and decreases communication among developers.

Moreover, the continuous evolution of software due to bugs removal, new features addition or existing features modification results in the source code complexity. The proposed model quantifies the complexity in the source code using the Shannon entropy measure. In addition, the issues fixing growth behavior is viewed as a function of continuation time of the software in the field environment and amount of uncertainty or complexity present in the source code. Therefore, a two-dimensional function called Cobb-Douglas production function is applied to model the intensity function of the issues fixing rate. Furthermore, the rate of fixing the different issue types is considered variable that may alter after certain time points. Thus, this study incorporates the concept of multiple change-points to predict and assess the fixing behavior of issues in the software system. The performance of the proposed model is validated by fitting the proposed model to the actual issues data of three open-source projects. Findings of the data analysis exhibit excellent prediction and estimation capability of the model.",10.1142/S0218539320400094

However, the use of arbitrary units has limited the usefulness of these data for many quantitative purposes. Calibration of fluorescence measurements from flow cytometry and plate reader spectrophotometry has been implemented previously, but the tools are disjointed.

The workflow is validated using Escherichia coli engineered to express green fluorescent protein (GFP) from a set of commonly used constitutive promoters. We then demonstrate the package's power by identifying the time evolution of distinct subpopulations of bacteria from bulk plate reader data, a task previously reliant on laborious flow cytometry or colony counting experiments.

Four-dimensional cine models allow for real-time visualization of cardiac structures during processes such as complex congenital heart disease. Such models can be used for patient and trainee education, and potentially for surgical planning. Currently, 3-D printed models are more commonly used, but they are static, showing only one selected phase of the cardiac cycle. Second, they are limited by the selection of clipping planes before printing. Four-dimensional segmentation and virtual reality visualization overcome these limitations.

Satellite remote sensing is the optimal tool to provide such data. Images from Synthetic Aperture Radar (SAR) satellite sensors are preferably used as they work regardless of cloud coverage during image acquisition. However, processing of SAR is more complicated and the sensors have development potential. Dealing with such a complexity, current studies should aim to be reproducible, open, and built upon free and open-source software (FOSS). Thereby, the data can be reused to develop and validate new algorithms or improve the ones already in use. This paper presents a case study of crop classification from microwave remote sensing, relying on open data and open software only. We used 70 multitemporal microwave remote sensing images from the Sentinel-1 satellite. A high-resolution, high-precision digital elevation model (DEM) assisted the preprocessing. The multi-data approach (MDA) was used as a framework enabling to demonstrate the benefits of including external cadastral data. It was used to identify the agricultural area prior to the classification and to create land use/land cover (LULC) maps which also include the annually changing crop types that are usually missing in official geodata. All the software used in this study is open-source, such as the Sentinel Application Toolbox (SNAP), Orfeo Toolbox, R, and QGIS.

Point-of-care analysis of glycated hemoglobin A (HbA(1c)) holds promise as a diagnostic test for diabetes mellitus in epidemiological studies in challenging environments with limited access to centralized biochemical labs. The HemoCue HbA1c 501 device can be used for point-of-care determination of HbA(1c), but its usability in epidemiological studies is limited by its inability to export results in digital format. We have developed the open source HemoDownloader software to overcome this limitation of the device. HemoDownloader has an easy-to-use graphical user interface and can export data from HemoCue HbA1c 501 to standard spreadsheet file formats. The program has the potential to improve data collection and management in epidemiological studies of diabetes mellitus.",10.1371/journal.pone.0242087
+1280,Article,Hidden Figures: Roles and Pathways of Successful OSS Contributors,"Open Source Software (OSS) development is a collaborative endeavor where expert developers, distributed around the globe create software solutions. Given this characteristic, OSS communities have been studied as technical communities, where stakeholders join and evolve in their careers based on their (often voluntary) code contributions to the project. However, the OSS landscape is slowly changing with more people and companies getting involved in OSS. This means that projects now need people in non-technical roles and activities to keep the project sustainable and evolving. In this paper, we focus on understanding the roles and activities that are part of the current OSS landscape and the different career pathways in OSS. By conducting and analyzing 17 interviews with OSS contributors who are well known in the community, we provide empirical evidence of the existence and importance of community-centric roles (e.g advocate, license manager, community founder) in addition to the well-known project-centric ones (e.g maintainer, core member). However, the community-centric roles typically remain hidden, since these roles may not leave traces in software repositories typically analyzed by researchers. We found that people can build a career in OSS through different roles and activities, with different backgrounds, including those not related to writing software. Furthermore, people's career pathways are fluid, moving between project and community-centric roles. Our work highlights that communities and researchers need to take action to acknowledge the importance of these varied roles, making these roles visible and well-recognized, which can ultimately help attract and retain more people in the OSS projects.",10.1145/3415251

Software developers author commits, and present them in a pull request to be inspected by maintainers and reviewers. The success and sustainability of communities depends on ongoing contributions, but rejections decrease motivation of contributors. We carried out a a qualitative study to understand the mechanisms of evaluating PRs in open source software (FOSS) communities from developers and maintainers perspective. We interviewed 30 participants from five different FOSS communities. The data shows that acceptance of contributions depends not only on technical criteria, but also significantly on social and strategic aspects. This paper identifies three PR governance styles found in the studied communities: (1) protective, (2) equitable and (3) lenient. Each one of these styles has its particularities. While the protective style values trustworthiness and reliability of the contributor, the lenient style believes in creating a positive and welcoming environment where contributors are mentored to evolve contributions until they meet the community standards. Despite the differences, these governance styles have a commonality, they all safeguard the quality of the software.",10.1145/3383219.3383242

In this paper, we investigate how developers contribute to IoT applications in the Open Source Software (OSS) context, to gain a deeper understanding of how their work differs from that of non-IoT applications. To that end, we conducted a quantitative analysis of a broad set of the 60 most popular publicly available IoT and non-IoT projects on GitHub. By comparing how developers contribute to these projects, our analysis provides insight into the purpose and characteristics of the code, the behavior of the contributors, and the maturity of the IoT software development ecosystem. Results reveal significant differences between IoT and non-IoT application development, in terms of how applications are realized, in the diversity of developers; specializations, and in how code is reused.

+1285,Article,Hybrid Overlap Filter for LiDAR Point Clouds Using Free Software,"Despite the large amounts of resources destined to developing filtering algorithms of LiDAR point clouds in order to obtain a Digital Terrain Model (DTM), the task remains a challenge. As a society advancing towards the democratization of information and collaborative processes, the researchers should not only focus on improving the efficacy of filters, but should also consider the users' needs with a view toward improving the usability and accessibility of the filters in order to develop tools that will provide solutions to the challenges facing this field of study. In this work, we describe the Hybrid Overlap Filter (HyOF), a new filtering algorithm implemented in the free R software environment. The flow diagram of HyOF differs in the following ways from that of other filters developed to date: (1) the algorithm is formed by a combination of sequentially operating functions (i.e., the output of the first function provides the input of the second), which are capable of functioning independently and thus enabling integration of these functions with other filtering algorithms; (2) the variable penetrability is defined and used, along with slope and elevation, to identify ground points; (3) prior to selection of the seed points, the original point cloud is processed with the aim of removing points corresponding to buildings; and (4) a new method based on a moving window, with longitudinal overlap between windows and transverse overlap between passes, is used to select the seed points. Our hybrid filtering method is tested using 15 reference samples acquired by the International Society of Photogrammetry and Remote Sensing (ISPRS) and is evaluated in comparison with 33 existing filtering algorithms. The results show that our hybrid filtering method produces an average total error of 3.34\\% and an average Kappa coefficient of 92.62\\%. The proposed algorithm is one of the most accurate filters that has been tested with the ISPRS reference samples.",10.3390/rs12071051

+1287,Article,IOCBIO Kinetics: An open-source software solution for analysis of data traces,"Biological measurements frequently involve measuring parameters as a function of time, space, or frequency. Later, during the analysis phase of the study, the researcher splits the recorded data trace into smaller sections, analyzes each section separately by finding a mean or fitting against a specified function, and uses the analysis results in the study. Here, we present the software that allows to analyze these data traces in a manner that ensures repeatability of the analysis and simplifies the application of FAIR (findability, accessibility, interoperability, and reusability) principles in such studies. At the same time, it simplifies the routine data analysis pipeline and gives access to a fast overview of the analysis results. For that, the software supports reading the raw data, processing the data as specified in the protocol, and storing all intermediate results in the laboratory database. The software can be extended by study- or hardware-specific modules to provide the required data import and analysis facilities. To simplify the development of the data entry web interfaces, that can be used to enter data describing the experiments, we released a web framework with an example implementation of such a site. The software is covered by open-source license and is available through several online channels. Author summary In biological and other types of experiments, we frequently record changes of some parameters in time or space. It is common to analyze the data by splitting the recording into smaller sections and relating it to some changes induced by the researchers. The steps involved in the analysis are: splitting of the data, fitting them to some function, relating the fit result to the change in the environment, and normalization. These steps are frequently done through several software packages, spreedsheets, and manual copy and paste between the programs. The software presented in this work allows to make all these analysis steps in one database in a manner that is easy, can be reproduced by others, and clearly tracks the history of all the analysis steps. In addition, it allows to link the experimental data with the description of the experiment, making it simple to perform tasks such as normalization of the recorded values, relating experimental recordings to the sample or animal, as well as extracting data from the laboratory database for publishing. The software is written to be easily extendable by user-defined modules to fit the analysis pipelines and is expected to improve the data analysis practices in research.",10.1371/journal.pcbi.1008475

The scientific literature presents several techniques that can be used to recognize the user's emotional state. However, many techniques involve the use of sensors that can result in financial costs and cause discomfort to the user. In this scenario, the recognition of the emotional state through the analysis of facial expressions presents itself as a useful and practical approach, since it does not involve the use of sensors attached to the user's body and executed in different types of devices. Despite these advantages, software that allow the analysis of facial expressions for free are still incipient, and performance evaluation of this type of software usually is not available. In order to contribute to this context and assist researchers who need this type of software, this study presents a comparative analysis of two open-source emotion recognition software ({''}CLMTrackr{''} and ``Face-api.js{''}) simulating different environmental conditions related to lighting and distance.

+1292,Article,Investigating the vulnerability fixing process in OSS projects: Peculiarities and challenges,"Although vulnerabilities can be considered and treated as bugs, they present numerous pe-culiarities compared to other types of bugs (canonical bugs in the remainder of the paper). A vulnerability adds functionality to a system, as it allows an adversary to misuse or abuse the system, while a canonical bug is an incomplete or incorrect implementation of a requirement, and thus degrades the functionality of the system. This difference can affect the fixing process of vulnerabilities. By mining the repositories of 6 open source projects, we characterize the differences in the fixing process between vulnerabilities and canonical bugs, highlighting critical issues which could represent challenges for future research. Results of our study demonstrate that: (i) more re-assignments (than the ones observed in canonical bugs) are required for finding the developers able to handle vulnerability-related bugs, (ii) developers' security-related skills should be profiled, to improve the efficiency of the security bug assignment tasks, and, consequently, reduce the re-assignments, and (iii) vulnerabilities require more effort, contributors and time to define the fixing strategy but smaller time to fix than canonical bugs.

Faced with such challenges of increasingly complicated software design, large-scale refactoring that radically restructures the architecture of the software can be one of the solutions. In this study, we investigate and illustrate how OSS contributors accomplish large-scale refactoring in OSS development in which there is no significant corporate participation. In our observations, as the costs of coordination requirements rise, OSS contributors increase coordination capability to manage dependencies among multiple sources during the large-scale refactoring periods. Our findings suggest that OSS contributors episodically use traditional coordination mechanisms during the large-scale refactoring periods. Our study provides actionable insights into how OSS contributors make joint action that cannot be achieved by individuals working independently and use the provision of rewards in order to achieve a shared, explicit goal of large-scale refactoring.",10.1504/IJISAM.2020.110552

Recent studies identified a variety of community smells and defined them as sub-optimal patterns connected to organizational-social structures in the software development community. To early detect and discover existence of potential community smells in a software project, we introduce, in this paper, a novel machine learning-based detection approach, named CSDETECTOR, that learns from various existing bad community development practices to provide automated support in detecting such community smells. In particular, our approach learns from a set of organizational-social symptoms that characterize the existence of potential instances of community smells in a software project. We built a detection model using Decision Tree by adopting the C4.5 classifier to identify eight commonly occurring community smells in software projects. To evaluate the performance of our approach, we conduct an empirical study on a benchmark of 74 open source projects from Github. Our statistical results show a high performance of CSDETECTOR, achieving an average accuracy of 96\\% and AUC of 0.94. Moreover, our results indicate that the CSDETECTOR outperforms two recent state-of-the-art techniques in terms of detection accuracy. Finally, we investigate the most influential community-related metrics to identify each community smell type.

+1303,InProceedings,Long-Term Evaluation of Technical Debt in Open-Source Software,"Background: A consistent body of research and practice have identified that technical debt provides valuable and actionable insight into the design and implementation deficiencies of complex software systems. Existing software tools enable characterizing and measuring the amount of technical debt at selective granularity levels; by providing a computational model, they enable stakeholders to measure and ultimately control this phenomenon. Aims: In this paper we aim to study the evolution and characteristics of technical debt in open-source software. For this, we carry out a longitudinal study that covers the entire development history of several complex applications. The goal is to improve our understanding of how the amount and composition of technical debt changes in evolving software. We also study how new technical debt is introduced in software, as well as identify how developers handle its accumulation over the long term. Method: We carried out our evaluation using three complex, open-source Java applications. All 110 released versions, covering more than 10 years of development history for each application were analyzed using SonarQube. We studied how the amount, composition and history of technical debt changed during development, compared our results across the studied applications and present our most important findings. Results: For each application, we identified key versions during which large amounts of technical debt were added, removed or both. This had significantly more impact when compared to the lines of code or class count increases that generally occurred during development. However, within each version, we found high correlation between file lines of code and technical debt. We observed that the Pareto principle was satisfied for the studied applications, as 20% of issue types generated around 80% of total technical debt. Interestingly, there was a large degree of overlap between the issues that generated most of the debt across the studied applications. Conclusions: Early application versions showed greater fluctuation in the amount of existing technical debt. We found application size to be an unreliable predictor for the quantity of technical debt. Most debt was introduced in applications as part of milestone releases that expanded their feature set; likewise, we identified releases where extensive refactoring significantly reduced the level of debt. We also discovered that technical debt issues persist for a long time in source code, and their removal did not appear to be prioritized according to type or severity.",10.1145/3382494.3410673

Developers often follow popular developers and projects for learning, technical selection, and collaboration. Thus, identifying popular developers and projects is very meaningful. In this paper, we propose a multiplex bipartite network ranking model, M-BiRank, to co-rank developers and projects using multiple developer-project interactions. Firstly, multiple developer-project interactions such as commit, issue, and watch are extracted and a multiplex developer-project bipartite network is constructed. Secondly, a random layer is selected from this multiplex bipartite network and initial ranking scores are calculated for developers and projects using BiRank. Finally, initial ranking scores diffuse to other layers and mutual reinforcement is taken into consideration to iteratively calculate ranking scores of developers and projects in different layers.

+1306,Article,MORE IS NOT NECESSARILY BETTER: AN ABSORPTIVE CAPACITY PERSPECTIVE ON NETWORK EFFECTS IN OPEN SOURCE SOFTWARE DEVELOPMENT COMMUNITIES,"Previous research has predominantly taken a social network perspective suggesting that building more network connections or becoming deeply embedded in a network provides a better position to access network knowledge in open source software communities. This perspective implicitly assumes that accessed network knowledge automatically gets absorbed and transferred to projects, so that building more and deeper network connections is beneficial: Drawing from an absorptive capacity perspective, this research challenges such conventional wisdom, arguing instead that the benefits depend on a project's absorptive capacity. Network connections provide access to external knowledge in the community; the absorption and transfer of this new knowledge require appropriate internal knowledge and developer roles. With longitudinal data collected from 4,518 open source software development projects hosted at Source-Forge, the authors show that knowledge breadth (depth) helps with the absorption of external knowledge achieved from network depth (breadth), but it inhibits the absorption of external knowledge obtained from network breadth (depth). Further, developer roles (e.g., bridge members, role diversity) can mitigate the negative consequences of suboptimal combinations and facilitate effective transfers of absorbed external knowledge across and within projects. These findings provide important theoretical and managerial implications for managing network connections, knowledge, and developer roles in open source software communities.",10.25300/MISQ/2020/13991

Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity. (C) 2019 The Authors.

Many individuals and organizations have purchased consumer-grade UAVs, and commonly acquire aerial photographs to map land cover. The resulting ultra-high-resolution (sub-decimeter-resolution) imagery has high information content, but automating the extraction of this information to create accurate, wall-to-wall land-cover maps is quite difficult. We introduce image-processing workflows that are based on open-source software and can be used to create land-cover maps from ultra-high-resolution aerial imagery. We compared four machine-learning workflows for classifying images. Two workflows were based on random forest algorithms. Of these, one used a pixel-by-pixel approach available in ilastik, and the other used image segments and was implemented with R and the Orfeo ToolBox. The other two workflows used fully connected neural networks and convolutional neural networks implemented with Nenetic. We applied the four workflows to aerial photographs acquired in the Great Basin (western USA) at flying heights of 10 m, 45 m and 90 m above ground level. Our focal cover type was cheatgrass (Bromus tectorum), a non-native invasive grass that changes regional fire dynamics. The most accurate workflow for classifying ultra-high-resolution imagery depends on diverse factors that are influenced by image resolution and land-cover characteristics, such as contrast, landscape patterns and the spectral texture of the land-cover types being classified. For our application, the ilastik workflow yielded the highest overall accuracy (0.82-0.89) as assessed by pixel-based accuracy.",10.1002/rse2.144

Three DHT11 temperature/humidity sensors were used to measure the inside and outside temperature as well as an anemometer with an air current speed sensor included for measuring air current speed. The greenhouse was equipped with roof and side wall ventilators. The ventilation rate was calculated via an equation where both wind and buoyancy effect were taken into consideration. The goal of this research was to develop an inexpensive system that could be used by the producers as a reliable and accurate tool for measuring environmental parameters inside greenhouses and other agricultural buildings. The results led to the conclusion that the greenhouse's ventilation rate was adequate and measurements were accurate. Therefore, the experimental system's operation was reliable making it a low-cost and energy-efficient solution for environmental management in agricultural buildings.",10.17660/ActaHortic.2020.1296.131

This research aims to construct a high-resolution bathymetric map by using open-source software. Lake Zebrus was selected as the study site, where fieldwork was performed to obtain the depth data and subsequently process to find optimal methodology for creating a bathymetric map. The methodology used in this research is modifiable for different purposes and is based on obtaining the best results from using open-source resources and knowledge of cartography. Lake Zebrus is an example how to perform accurate and state of the art bathymetric survey in a short time period. The area of Lake Zebrus is 417.57 ha. The lake has a small crooked coastline. Lake Zebrus has a maximum depth of 4.45 m and an average depth of 1.48 m. Results from the bathymetric survey can be used for further research based on depth data. The research tasks are accomplished as the methodology selected is repeatable in the other lakes.

The success of an open source software development (OSSD) community is often attributed to the underlying governance model, and a key component of these models is the decision-making (DM) process. While there have been studies on the decision-making processes publicized by OSS communities (e.g., through published process diagrams), little has been done to study decision-making processes that can be extracted using a bottom-up, data-driven approach, which can then be used to assess whether the publicized processes conform to the extracted processes. To bridge this gap, we undertook a large-scale data-driven study to understand how decisions are made in an OSSD community, using the case study of Python Enhancement Proposals (PEPs), which embody decisions made during the evolution of the Python language. Our main contributions are:(a) the design and development of a framework using information retrieval and natural language processing techniques to analyze the Python email archives (comprising 1.48 million emails), and(b) the extraction of decision-making processes that reveal activities that are neither explicitly mentioned in documentation published by the Python community nor identified in prior research work.

+1315,Article,Modeling continuous security: A conceptual model for automated DevSecOps using open-source software over cloud (ADOC),"Agile software development methodology and DevOps, together, have helped the business to achieve agility and velocity in delivering time-to-market applications and services. Open-source software (OSS) and cloud technologies are taking up business innovation and DevOps at new heights. However, in the quest of agility and velocity, user data security and privacy assurance often get lower priority as they are perceived as a time-consuming activity requiring specialized people, process, and technology. We see this problem being addressed by integrating security in DevOps processes. Security for DevOps has been in-stitutionalized as DevSecOps with practical considerations for a given business context. In this work, we proposed a conceptual security model, ADOC, to facilitate adopting DevSecOps for the business processes capitalizing OSS over the cloud. This work contributes towards the following to integrate continuous se-curity in application and service delivery: (i) A continuous security conceptual framework proposal based on the requirements elicited from the analysis of challenges in adopting DevSecOps using OSS over the cloud. (ii) An integrationist security model, ADOC, based on the proposed continuous security conceptual framework, integrating development, security, and operation activities through automation of security controls using OSS over the cloud. (iii) A set of inter-working OSS tools for automation of the proposed security controls in ADOC workflow and practices. (iv) A set of metrics for performance measurement of the ADOC model. (v) Mapping of the solutions for the analyzed challenges using the proposed secu-rity controls, followed by a use case scenario to adopt the ADOC workflow and continuous practices. The ADOC transforms security being adhoc compliance-oriented activities into continuous assurance-oriented activities by codifying security controls into an automated delivery workflow. Its practical adoption en-ables businesses to deliver time-to-market security ready applications and services with accelerated ve-locity and sustainable agility in a cost-effective way.

+1317,InProceedings,Modelling and simulation of ingot solidification with the open-source software Code\\_Saturne,"In order to address the issue of macro-segregations in large industrial ingots, a solidification model has been recently developed in Code\\_Saturne, the general purpose open-source Computational Fluid tablDynamics (CFD) software developed and released by EDF R\\&D. This model is a liquid-solid mixture model inspired from the pioneer work of Bennon and Incropera, including mass, momentum, energy and species conservation equations. In particular, the energy conservation equation is formulated with the temperature variable, the thermosolutal convection is accounted for through the Boussinesq approximation and the interdendritic flow in the mushy zone is governed by the Darcy's law. Furthermore, a rigid solid phase is assumed and classical microsegregation models are used featuring lever-rule or Gulliver-Scheil assumptions. At the discrete level, a first-order upwind scheme is implemented with a SIMPLEC approach to solve the velocity-pressure coupling. The other couplings involving temperature and concentration fields are efficiently solved performing sub-loops with a PISO-like approach. The overall scheme is mainly implicit with additional treatments to ensure the equilibrium between the hydrostatic pressure gradient and the buoyant forces, and to deal properly with solid zones. The segregation predictions offered by the model are validated against both academic test case and industrial ingot configurations. A convergence study is also led focusing on time step and mesh size sensitivities.",10.1088/1757-899X/861/1/012033

+1320,Article,OPEN-SOURCE SOFTWARE FOR ULTRASOUND-BASED GUIDANCE IN SPINAL FUSION SURGERY,"Spinal instrumentation and surgical manipulations may cause loss of navigation accuracy requiring an efficient re-alignment of the patient anatomy with pre-operative images during surgery. While intra-operative ultrasound (iUS) guidance has shown clear potential to reduce surgery time, compared with clinical computed tomography (CT) guidance, rapid registration aiming to correct for patient misalignment has not been addressed. In this article, we present an open-source platform for pedicle screw navigation using iUS imaging. The alignment method is based on rigid registration of CT to iUS vertebral images and has been designed for fast and fully automatic patient re-alignment in the operating room. Two steps are involved: first, we use the iUS probe's trajectory to achieve an initial coarse registration; then, the registration transform is refined by simultaneously optimizing gradient orientation alignment and mean of iUS intensities passing through the CT-defined posterior surface of the vertebra. We evaluated our approach on a lumbosacral section of a porcine cadaver with seven vertebral levels. We achieved a median target registration error of 1.47 mm (100\\% success rate, defined by a target registration error <2 mm) when applying the probe's trajectory initial alignment. The approach exhibited high robustness to partial visibility of the vertebra with success rates of 89.86\\% and 88.57\\% when missing either the left or right part of the vertebra and robustness to initial misalignments with a success rate of 83.14\\% for random starts within +/- 20 degrees rotation and +/- 20 mm translation. Our graphics processing unit implementation achieves an efficient registration time under 8 s, which makes the approach suitable for clinical application.

It will be shown how a Volume Conductor Model (VCM) is constructed and examined using Python-controlled algorithms for generation, discretization and adaptive mesh refinement of the computational domain, as well as for incorporation of heterogeneous and anisotropic properties of the tissue and allocation of neuron models. The utilization of the platform is facilitated by a collection of predefined input setups and quick visualization routines. The accuracy of a VCM, created and optimized by the platform, was estimated by comparison with a commercial software. The results demonstrate no significant deviation between the models in the electric potential distribution. A qualitative estimation of different physics for the VCM shows an agreement with previous computational studies. The proposed computational platform is suitable for an accurate estimation of electric fields during DBS in scientific modeling studies. In future, we intend to acquire SDA and EMA approval.

In order to effectively promote the growth of online secondhand markets, this paper designs and validates a scale to assess customer perception of the service quality of secondhand products purchased via online platforms. Complementarily, the paper assesses how each of the different dimensions that configure the scale contributes to explaining the fulfillment of customers' expectations. The scale is defined by 23 items and is arranged in 5 dimensions from the literature on online commerce as well as on the sharing economy. A sample of 200 questionnaires is used for exploratory factor analysis. A second sample of 507 users is used for confirmatory factor analysis. The quality perceived by online customers of secondhand products depends on the quality of the interactions that they have with the website, with the vendor, and with the product. The dimension that contributes the most to customer fulfillment of expectations is product quality. Findings identify the items that contribute the most to quality perception and fulfillment of expectations, facilitating the development of more effective strategies for platform owners and vendors who want to attract and retain customers of secondhand products. Complementarily, these findings are useful to businesses and governments that want to promote a more sustainable economy by reducing consumption of new products and promoting reutilization of existing ones.",10.3390/su12219256
+1325,Article,On the fulfillment of coordination requirements in open-source software projects: An exploratory study,"In large-scale open-source software projects, where developers are often distributed across the entire planet, coordination among developers is crucial. To estimate whether a state ofsocio-technical congruenceis achieved, which is associated with software quality and project success, we assess the alignment of collaboration and communication in such software projects in terms ofcoordination requirements. By means of an empirical study on a substantial set of large-scale open-source software projects-the development histories of all projects sum up to over 180 years-we aim at shedding light on this issue. To this end, to take a more semantic view on this phenomenon in comparison to previous work, we do not only identify coordination requirements arising from files and functions only, but also those arising from features. We found that open-source developers fulfill coordination requirements intentionally, but mostly those coordination requirements that arise from coupled source-code artifacts, while they resolve simpler ones independently. Furthermore, neither of the considered abstraction levels of source-code artifacts (files, functions, features) is more suitable to construct coordination requirements with respect to their fulfillment. This finding strongly indicates that features do not play an as important role in the development process as expected and commonly believed by the research community in the area of feature-oriented and feature-driven development. Finally, we identified notable evolutionary trends in the fulfillment of coordination requirements and showed that far-reaching social events (such as organizational issues) have a huge impact on their fulfillment, both negatively and positively. The key findings of our empirical study are that socio-technical relations are important to understand open-source development communities and that the incorporation of different abstraction levels for developer collaboration does yield important insights to further improve the evolution in open-source software projects.",10.1007/s10664-020-09833-8

Besides this fact, it is recognized by the OSS community the need to understand OSS development process and its activities. Our goal is to investigate the state-of-art about OSS process through conducting a systematic literature review providing an overview of how the OSS community has been investigating OSS process over past years. We identified and summarized OSS process activities and their characteristics and translated them into an OSS macro process using BPMN notation. As a result, we systematically analyzed 33 studies presenting an overview of the OSS process research and a generalized OSS development macro process represented by BPMN notation with a detailed description of each OSS process activity and roles in OSS environment. We conclude that OSS process can be in practice further investigated by researchers. In addition, the presented OSS process can be used as a guide for OSS projects and be adapted according to each OSS project reality.

Various thematic maps such as lithology/hydrogeology, soil, land-cover/use, slope, lineament density, drainage density and rainfall distribution were integrated in QGIS software. Vector input layers were rasterized and resampled using QGIS wrap projection function to make sure that the grid cells are of the same size. Reclassification using SAGA and GRASS reclass algorithms in QGIS was carried out to realign the factor classes in a consistent scale, and reclassification to a scale of 1 to 5 was carried out to harmonize the results. The study identified a number of potential areas for groundwater recharge, groundwater exploration, groundwater development and potential areas for artificial groundwater recharge. Potential groundwater recharge zones for the Singida semi-arid fractured aquifer are restricted to areas with high lineament density, cultivated areas, grassland and flat to gentle slopes. The potential of groundwater recharge is also observed in areas with low drainage density. The delineated zones provide a good understanding of the potential recharge zones, which are a starting point for recharge zone protection. This blended approach can be utilized for carrying out suitability analysis using the weighted overlay analysis approach. Areas designated good and very good are recommended for artificial recharging structures as an alternative technique for enhancing groundwater recharge through rainwater harvesting. This will help to augment groundwater storage in this semi-arid environment.",10.3390/hydrology7020028

In the hope of facilitating this exploration and promoting the reproducibility of geophysical simulations and inversions, we have developed the open-source software package SimPEG. The software has been designed to be modular and extensible, with the goal of allowing researchers to interrogate all of the components and to facilitate the exploration of new inversion strategies. We present an overview of the software in its application to airborne electromagnetics and demonstrate its use for visualising fields and fluxes in a forward simulation, as well as its flexibility in formulating and solving the inverse problem.

+1340,InProceedings,Processing and indexing of electron backscatter patterns using open-source software,"A new method to increase the signal-to-noise ratio S/N of electron backscatter patterns (EBSPs) based upon principal component analysis (PCA) is presented. The PCA denoising method is applied to ten scans of EBSPs from the same region of interest of a recrystallised nickel sample acquired with a decreasing S/N, achieved by reducing the exposure time while increasing the camera gain accordingly. That PCA denoising increases S/N in EBSPs is demonstrated by comparing indexing success rates after both Hough and dictionary indexing (HI and DI) of the Ni patterns having undergone one of four processing routes: i) standard static and dynamic background corrections (standard corrections), ii) standard corrections and pattern averaging with the four closest neighbours, iii) standard corrections and PCA denoising, and iv) standard corrections and pattern averaging followed by PCA denoising. Both pattern averaging and PCA denoising increases the indexing success rates for both indexing approaches for the studied Ni scans, with the former processing route providing the better success rates. The best success rates are obtained after pattern averaging followed by PCA denoising. The potential of PCA denoising to reveal additional pattern details compared to standard corrections and pattern averaging is demonstrated in a pattern from an orthoclase (KAlSi3O8) grain in a geological sample.

Then, we employed a survey (n=30) to map the strategies to challenges and collect additional strategies. Our study identified 7 challenges and 13 strategies related to task recommendation. Strategies such as ``tagging the issues based on difficulty,{''} ``adding documentation,{''} ``assigning a small task first and then challenge the newcomers with bigger tasks:' and ``dividing tasks into smaller pieces{''} were frequently mentioned as ways to overcome multiple challenges.

Several established non-commercial inversion codes exist, but they typically require advanced knowledge to use effectively. ResIPy was developed to provide a more intuitive, user-friendly, approach to inversion of geoelectrical data, using an open source graphical user interface (GUI) and a Python application programming interface (API). ResIPy utilizes the mature R2/cR2 inversion codes for ERT and IP, respectively. The ResIPy GUI facilitates data importing, data filtering, error modeling, mesh generation, data inversion and plotting of inverse models. Furthermore, the easy to use design of ResIPy and the help provided inside makes it an effective educational tool. This paper highlights the rationale and structure behind the interface, before demonstrating its capabilities in a range of environmental problems. Specifically, we demonstrate the ease at which ResIPy deals with topography, advanced data processing, the ability to fix and constrain regions of known geoelectrical properties, time-lapse analysis and the capability for forward modeling and survey design.",10.1016/j.cageo.2020.104423

Herein, sodium dodecyl benzene sulfonate (SDBS) in spinning solution has been found to stimulate fibrous materials forming 3D candy-floss-like structure with high porosity and surface area. Also, SDBS doped on fibers surface facilitates dye adsorption and oil separation of the fibrous materials in effluent. Environmentally friendly SDBS-driven 3D electrospun PLLA fibrous materials have high porosity (99.91\\%) and stable big pore size (7.39 mu m), showing high adsorption capacity of 581.78 mg g(-1)toward methylene blue (MB) and 14.67 times improved oil/water separation efficiency compared to traditional 2D PLLA fibrous materials. Moreover, the concept of SDBS stimulated 3D nanofibrous materials can be readily extended to other polymers, paving a new way to fabricate high-efficient dye adsorption and oil/water separation 3D fibrous filters for industrial waste water remediation.",10.1002/mame.202000368

+1349,InProceedings,SoftMon: A Tool to Compare Similar Open-source Software from a Performance Perspective,"Over the past two decades, a rich ecosystem of open-source software has evolved. For every type of application, there are a wide variety of alternatives. We observed that even if different applications that perform similar tasks and compiled with the same versions of the compiler and the libraries, they perform very differently while running on the same system. Sadly prior work in this area that compares two code bases for similarities does not help us in finding the reasons for the differences in performance. In this paper, we develop a tool, SoftMon, that can compare the codebases of two separate applications and pinpoint the exact set of functions that are disproportionately responsible for differences in performance. Our tool uses machine learning and NLP techniques to analyze why a given open-source application has a lower performance as compared to its peers, design bespoke applications that can incorporate specific innovations (identified by SoftMon) in competing applications, and diagnose performance bugs. In this paper, we compare a wide variety of large open-source programs such as image editors, audio players, text editors, PDF readers, mail clients and even full-fledged operating systems (OSs). In all cases, our tool was able to pinpoint a set of at the most 10-15 functions that are responsible for the differences within 200 seconds. A subsequent manual analysis assisted by our graph visualization engine helps us find the reasons. We were able to validate most of the reasons by correlating them with subsequent observations made by developers or from existing technical literature. The manual phase of our analysis is limited to 30 minutes (tested with human subjects).",10.1145/3379597.3387444

National user groups can bolster these international communities by convening local events, championing the software to peers, welcoming and onboarding new contributors, raising money to support the broader community, and collecting important information on user's needs. The open source community-led software DSpace has had great success encouraging the creation of national user groups; in the UK, North America, and Germany, the Groups have been active for many years. However, it was in 2018, thanks to a renewed focus on international engagement and more diverse representation of the global community in governance groups, that the national communities entered into a new phase: 15 new national User Groups have been formed all over the world since then, while the German user group evolved into the ``DSpace-Konsortium Deutschland{''}, founded by 25 institutions, marking a pivotal point for membership options and National User Group participation within DSpace Governance. This article will offer an overview of the historical development of the DSpace community and its governance model, as well as DuraSpace's international engagement strategy, including its benefits and challenges.

However, the majority of OSS products fail to gain much interest. Identifying early success is important for catalyzing growth in OSS markets. However, previous OSS research has not examined early product success dynamics and assumes adoption to be a continuous process. We propose OSS takeoff in adoptions as a measure of eventual product success. Takeoff is a nonlinear inflection point separating the early development from the growth phase in the product lifecycle. Using arguments from the signaling literature, we propose that community activities send signals about product quality and reduce information asymmetry faced by potential adopters of OSS products. Estimating a Cox proportional hazard model using a large sample of OSS products from SourceForge, we find that takeoff times are significantly associated with signals of quality deficiency and improvement. Further, we find that target audience and product innovativeness moderate this relationship.",10.25300/MISQ/2020/12576
+1356,Article,THE USE OF A FREE SOFTWARE FOR DETERMINATION OF THE INTERNAL FORCES OF LIVE LOADS IN BEAMS OF CONCRETE BRIDGES,"Ftool is used in civil engineering due to its facilities and simplifications in structural modeling; for not requiring robust computers for its use; not having high processing time in the analyzes, being generally fast and for being a free software. It allows the creation of live loads, and these are used in calculating the envelope of internal forces in bridge beams. Despite this, a significant number of projects, dissertations and theses in the area of bridges, especially in graduate courses, still do not use it in the analysis of life loads in bridge beams. In this sense, this project aims to encourage the use of Ftool to carry out structural analysis in beams of bridge beams, whether in determining the respective lines of influence or internal efforts; so that graduate students and researchers start to use it in their respective projects. Four numerical examples are developed and each one uses paid software, SAP2000, Ansys or GAP-GEL v1, and the results are compared with Ftool. In all examples, the variations in the results are less than 9\\%, in the worst case, but in most of them, this variation is less than 3\\%. These differences can be considered as acceptable, since, later, different coefficients are applied. Finally, the Ftool proved to be effective and robust, with reliable results and, therefore, recommended for the determination of the different internal and TTL efforts in the beams, due to different live loads acting on bridge decks composed of two, three, seven and eight beams. Without the need to use more complex and paid software to carry out such analyzes.",10.15628/holos.2020.9466

This collaboration between corporate professionals and open source software community members is strikingly different from the early days of software development where for-profit firms attempted to dominate and control the industry while attempting to throttle the success of independent developers offering an alternative, open source option. While many metaphors like trading zones, common pool resources and ecosystems have helped understand the phenomenon, the metaphors do not portray what the industry was like before and after the transition. We adopt a postcolonial metaphor as an analytical lens to examine such collaboration based on qualitative data gathered over three years from executives, managers and developers within corporations that engage in open source software development. Drawing on these insights, we then theorize a ``Third Design Space,{''} based on the concept of the third space proposed by Bhabha. This metaphor encourages the cultivation of a new design environment, creation of new design associations and circulation of shared design resources. Together these practices and behaviours make it possible to nurture innovative methods and new rituals for designing software with results and methods that represent a distinct departure from the competitive and proprietary past, even creating innovative artefacts that could not have been created without the Third Design Space.",10.1111/isj.12270

While we can attribute identified peripheral contributions (IPC) to specific individuals and OSS projects need them to succeed, one cannot trace back anonymous peripheral contributions (APC), and they can have both positive and negative ramifications for project development. Open platforms and managers face a challenging design choice in deciding whether to allow APC and for which tasks or what type of projects. We examine the impact that the ratio between APC and IPC has on OSS project performance. Our results suggest that the OSS projects perform the best when they contain a uniform anonymity level (i.e., they contain predominantly APC or predominantly IPC). However, our results also suggest that OSS projects have lower performance when the ratio between APC and IPC nears one (i.e., they contain close to the same number of APC and IPC). Furthermore, our results suggest that these results differ depending on the type of application that a project develops.

+1376,InProceedings,URBANopt: AN OPEN-SOURCE SOFTWARE DEVELOPMENT KIT FOR COMMUNITY AND URBAN DISTRICT ENERGY MODELING,"Urban building modeling tools are developing rapidly; these tools use emerging simulation workflows for specific urban environmental design tasks, such as assessing the impacts of energy efficiency technologies at a district scale. However, with the emergence of new environmental design tasks, addressing all possible use cases and tasks is challenging and cannot be covered by a single tool. Urban-scale analysis at this level of complexity often requires linking multiple emerging tools, rather than using a single tool, to adequately evaluate a variety of possible fields in urban environmental design. To achieve this, flexible platforms are needed to support multiple input formats (e.g., geometric and non-geometric building properties), enabling the mapping of such inputs to underlying simulation engines. This paper provides an overview of the open-source URBANopt Software Development Kit (SDK) for modeling high-performance buildings and energy systems at a district scale. URBANopt's flexible SDK is composed of several modules that can be customized to integrate with other tools and generate new workflows to perform urban environmental design tasks, such as capturing interactions between individual buildings, district energy systems, distributed energy resources, and the electric distribution grid. We describe the functionality of the core SDK modules in URBANopt (called Core Gem, GeoJSON Gem, and Scenario Gem) and discuss the flexibility of these modules as a means of integration with a variety of tools. We also document and demonstrate technical details of writing and combining new modules to create customized workflows.

Infrequent contributions are part of a trend which has been widely observed in other sectors of volunteering, where it has been termed ``episodic volunteering{''} (EV). Previous FLOSS research has focused on the Onion model, differentiating core and peripheral developers, with the latter considered as a homogeneous group. We argue this is too simplistic, given the size of the periphery group and the myriad of valuable activities they perform beyond coding. Our exploratory qualitative survey of 13 FLOSS communities investigated what episodic volunteering looks like in a FLOSS context. EV is widespread in FLOSS communities, although not specifically managed. We suggest several recommendations for managing EV based on a framework drawn from the volunteering literature.

Therefore, when studying this kind of project, collecting and analyzing texts and artifacts can promote a more comprehensive understanding of the phenomenon and the variety of organizational settings. However, despite the importance of examining Grey Literature (GL), such as technical reports, white papers, magazines, and blog posts for studying FLOSS projects, the GL Review is still an emerging technique in software engineering studies, lacking a well-established investigative methodology.

To propose a model for the acceptance of OSS; investigate the influence of the OSS characteristics, UTAUT constructs, and infrastructure factors on the acceptance of open source software system. It also examines the validity of UTAUT in the open source software context. Quantitative design has been used following the distribution of questionnaire among a sample of 255 individuals employed at public and private organizations (172 males and 83 females).

+1385,Article,Using Ensembles for Class-Imbalance Problem to Predict Maintainability of Open Source Software,"To facilitate software maintenance and save the maintenance cost, numerous machine learning (ML) techniques have been studied to predict the maintainability of software modules or classes. An abundant amount of effort has been put by the research community to develop software maintainability prediction (SMP) models by relating software metrics to the maintainability of modules or classes. When software classes demanding the high maintainability effort (HME) are less as compared to the low maintainability effort (LME) classes, the situation leads to imbalanced datasets for training the SMP models. The imbalanced class distribution in SMP datasets could be a dilemma for various ML techniques because, in the case of an imbalanced dataset, minority class instances are either misclassified by the ML techniques or get discarded as noise. The recent development in predictive modeling has ascertained that ensemble techniques can boost the performance of ML techniques by collating their predictions. Ensembles themselves do not solve the class-imbalance problem much. However, aggregation of ensemble techniques with the certain techniques to handle class-imbalance problem (e.g., data resampling) has led to several proposals in research. This paper evaluates the performance of ensembles for the class-imbalance in the domain of SMP. The ensembles for class-imbalance problem (ECIP) are the modification of ensembles which pre-process the imbalanced data using data resampling before the learning process. This study experimentally compares the performance of several ECIP using performance metrics Balance and g-Mean over eight Apache software datasets. The results of the study advocate that for imbalanced datasets, ECIP improves the performance of SMP models as compared to classic ensembles.",10.1142/S0218539320400112
+1386,Article,Using open-source software and digital imagery to efficiently and objectively quantify cover density of an invasive alien plant species,"The most commonly used method for measuring vegetation cover is visual estimation, which is highly subjective, potentially leading to measurement errors. This poses serious implications to the assessment and continued management of plant species cover, for example in the control of invasive plant species. Morphological analysis of digital imagery has, to date, been primarily applied in the classification of landscape features. Our novel application of morphological image analysis provides an objective method for detection and accurate cover assessment of an invasive alien plant species (IAS), giving reduced measurement errors when compared to visual estimation. Importantly, this method is entirely based on free software. Guidos Toolbox is a collection of generic raster image processing routines, including Morphological Spatial Pattern Analysis (MSPA), which classifies and quantifies features according to shape. MSPA was employed in this study to detect and quantify cover of invasive Petasites pyrenaicus (Winter heliotrope) in digital images of 1 m x 1 m plots. Its efficacy was compared to that of two other methods- GIS Digitisation (used as an accurate baseline) and Visual Estimation (standard method). We tested the limit of MSPA usability on images of varying complexity, i.e. ``simple{''}, intermediate{''} or ``complex{''}, depending on presence/absence of other vascular plant species and the species richness of plot. Our results show good agreement between all three methods. MSPA measurement of P. pyrenaicus cover was most closely aligned with the GIS Digitisation (concordance correlation coefficients of 0.966). Visual Estimation was less closely aligned with GIS Digitisation (concordance correlation coefficients of 0.888). However, image complexity resulted in differing levels of agreement; with the closest agreement being achieved between MSPA and GIS Digitisation when used on images of lower and higher complexity. MSPA consistently provides higher accuracy and precision for P. pyrenaicus cover measurement than the standard Visual Estimation method. Our methodology is applicable to a range of focal vegetation species, both herbaceous and graminoid. Future application of MSPA for larger-scale surveying and monitoring via remote sensing is discussed, potentially reducing resource demands and increasing cover measurement consistency and accuracy. We recommend this method forms part of vegetation management toolkits for not only environmental managers, but for anyone concerned with plant cover assessment, from agricultural systems to sustainable resource use.",10.1016/j.jenvman.2020.110519

Open source licenses determine the rules, under which the open source software can be further used and distributed. Previous works have examined the usage of open source licenses in the framework of specific projects or online social coding platforms, examining developers specific licensing views for specific software. However, the questions practitioners ask about licenses and licensing as captured in Question and Answer websites also constitute an important aspect toward understanding practitioners general licenses and licensing concerns. In this paper, we investigate open source license discussions using data from the Software Engineering, Open Source and Law Stack Exchange sites that contain relevant data. We describe the process used for the data collection and analysis, and discuss the main results that can be useful for developers, educators and license authors. Our results indicate that clarifications about specific licenses and specific license terms are required.",10.1109/SEAA51224.2020.00022
+1394,InProceedings,What to Expect from Code Review Bots on GitHub? A Survey with OSS Maintainers,"Software bots are used by Open Source Software (OSS) projects to streamline the code review process. Interfacing between developers and automated services, code review bots report continuous integration failures, code quality checks, and code coverage. However, the impact of such bots on maintenance tasks is still neglected. In this paper, we study how project maintainers experience code review bots. We surveyed 127 maintainers and asked about their expectations and perception of changes incurred by code review bots. Our findings reveal that the most frequent expectations include enhancing the feedback bots provide to developers, reducing the maintenance burden for developers, and enforcing code coverage. While maintainers report that bots satisfied their expectations, they also perceived unexpected effects, such as communication noise and newcomers' dropout. Based on these results, we provide a series of implications for bot developers, as well as insights for future research.",10.1145/3422392.3422459
+1396,Article,"What to share, when, and where: balancing the objectives and complexities of open source software contributions","Context: Software-intensive organizations' rationale for sharing Open Source Software (OSS) may be driven by both idealistic, strategic and commercial objectives, and include both monetary as well as non-monetary benefits. To gain the potential benefits, an organization may need to consider what they share and how, while taking into account risks, costs and other complexities. Objective: This study aims to empirically investigate objectives and complexities organizations need to consider and balance between when deciding on what software to share as OSS, when to share it, and whether to create a new or contribute to an existing community. Method: A multiple-case study of three case organizations was conducted in two research cycles, with data gathered from interviews with 20 practitioners from these organizations. The data was analyzed qualitatively in an inductive and iterative coding process. Results: 12 contribution objectives and 15 contribution complexities were found. Objectives include opportunities for improving reputation, managing suppliers, managing partners and competitors, and exploiting externally available knowledge and resources. Complexities include risk of loosing control, risk of giving away competitive advantage, risk of creating negative exposure, costs of contributing, and the possibility and need to contribute to an existing or new community. Conclusions: Cross-case analysis and interview validation show that the identified objectives and complexities offer organizations a possibility to reflect on and adapt their contribution strategies based on their specific contexts and business goals.",10.1007/s10664-020-09855-2

To this end, three contributions in the form of open-source software projects are presented in this paper. First, a community-driven wind turbine baseline controller, the Delft Research Controller (DRC), is presented. The DRC is applicable to high-fidelity simulation software that uses the DISCON controller interface. The controller distinguishes itself by the variety of available control and estimation implementations, its ease of use, and the universal applicability to wind turbine models. Secondly, in the wake of the DRC, the SimulinkDRC graphical controller design and compilation environment has been developed. Users having access to Simulink can benefit from the convenient way of controller development the tool provides. Finally, the FASTTool has been developed for educational purposes, by focusing on the graphical aspect of wind turbine (controller) design. The tool simplifies interaction with the advanced FAST simulation software, by comprehensive visualizations and analysis tools. This paper demonstrates and describes the functionality of all three software projects.",10.1088/1742-6596/1452/1/012010
+1398,InProceedings,Work Practices and Perceptions from Women Core Developers in OSS Communities,"Background. The effect of gender diversity in open source communities has gained increasing attention from practitioners and researchers. For instance, organizations such as the Python Software Foundation and the OpenStack Foundation started actions to increase gender diversity and promote women to top positions in the communities. Problem. Although the general underrepresentation of women (a.k.a. horizontal segregation) in open source communities has been explored in a number of research studies, little is known about the vertical segregation in open source communities---which occurs when there are fewer women in high level positions. Aims. To address this research gap, in this paper we present the results of a mixed-methods study on gender diversity and work practices of core developers contributing to open-source communities. Method. In the first study, we used mining-software repositories procedures to identify the core developers of 711 open source projects, in order to understand how common are women core developers in open source communities and characterize their work practices. In the second study, we surveyed the women core developers we identified in the first study to collect their perceptions of gender diversity and gender bias they might have observed while contributing to open source systems. Results. Our findings show that open source communities present both horizontal and vertical segregation (only 2.3% of the core developers are women). Nevertheless, differently from previous studies, most of the women core developers (65.7%) report never having experienced gender discrimination when contributing to an open source project. Finally, we did not note substantial differences between the work practices among women and men core developers. Conclusions. We reflect on these findings and present some ideas that might increase the participation of women in open source communities.",10.1145/3382494.3410682

+1401,Article,3D Virtual Planning for Rhinoplasty Using a Free Add-On for Open-Source Software,"Background: Rhinoplasty is one of the most frequent aesthetic surgeries; the procedure can be challenging for inexperienced surgeons, and positive outcomes depend on good communication with the patient, proper planning, and precise execution. Three-dimensional (3D) technology has emerged to address these issues, but specific software for 3D planning tends to be expensive. Objectives: This study presents a simple, low-cost method for 3D simulation to plan rhinoplasty. Methods: This preliminary report describes 3D rhinoplasty planning in a series of 3 cases employing free software and an add-on especially developed for rhinoplasty (Blender and RhinOnBlender, respectively). The photogrammetry protocol, which can be performed easily with a smartphone, is described in detail along with all the steps in 3D planning. Results: The software and add-on automated the process, making the tool environment accessible to surgeons who are not familiar with graphic design software. The surgeries were uneventful in all cases, and the patients were satisfied with the outcomes. Conclusions: 3D graphic technology has provided significant advances in health research, improvement, and teaching for surgeons and communication between surgeons and patients. Free open-source software and add-ons are excellent options that offer proven utility, affordability, and ease of utilization to healthcare providers.",10.1093/asj/sjab085
+1402,Article,A Semi-Automatic Method to Create an Affordable Three-Dimensional Printed Splint Using Open-Source and Free Software,"Three-dimensional (3D) printed splints are becoming more feasible in recent years, showing promising lightweight, waterproof, and hygienic designs. A typical procedure to create 3D printed splints is obtaining the geometry of a body segment using a 3D scanner, creating a 3D printable splint model based on the geometry of the body segment, and 3D printing the splint. As technologies of 3D scanning and 3D printing become mature gradually, the main challenge to fabricate 3D printed splint is to create 3D printable splint models. To solve this challenge, researchers have proposed various methods to design 3D splint models. However, most methods require extensive 3D modeling skills that medical professionals are lacking. In this work, a semi-automatic method is proposed to create a 3D printable model. Given the geometry of a body segment obtained through a 3D scanner, the method includes three key steps: (1) create a draft splint lattice structure, (2) optimize the splint structure, and (3) create a 3D printable model based on the optimized structure. All the software adopted for this method is free and readily available, and thus, there is no additional cost to convert from a scanned geometry of a body segment to a 3D printable splint model. Because the majority of the work is done automatically, with initial training, a medical professional should be able to create a 3D printable model using the proposed method, given the geometry of a body segment. The proposed method is demonstrated by creating a 3D printed wrist splint and the demo is uploaded into GitHub, a popular open-source platform.",10.7759/cureus.13934
+1403,InProceedings,A Study of Maintainability in Evolving Open-Source Software,"Our study is focused on an evaluation of the maintainability characteristic in the context of the long-term evolution of open-source software. According to well established software quality models such as the ISO 9126 and the more recent ISO 25010, maintainability remains among key quality characteristics alongside performance, security and reliability. To achieve our objective, we selected three complex, widely used target applications for which access to their entire development history and source code was available. To enable cross-application comparison, we restricted our selection to GUI-driven software developed on the Java platform. We focused our examination on released versions, resulting in 111 software releases included in our case study. These covered more than 10 years of development for each of the applications. For each version, we determined its maintainability using three distinct quantitative models of varying complexity. We examined the relation between software size and maintainability and studied the main drivers of important changes to software maintainability. We contextualized our findings using manual source code examination. We also carried out a finer grained evaluation at package level to determine the distribution of maintainability issues within application source code. Finally, we provided a cross-application analysis in order to identify common as well as application-specific patterns.",10.1007/978-3-030-70006-5\\_11
+1404,Article,A funfair without the candy floss: engaging communities to prevent diabetes in Nepal,"Objectives: The World Health Organization estimates that 422 million people have diabetes, three-quarters of whom live in low- and middle-income countries. Global action plans to address non-communicable diseases (NCDs) recognise the centrality of community engagement to create an enabling environment within which to address risk factors. Study design: In this article, we describe and critically reflect on a cocreated community engagement approach to address type 2 diabetes in the southern plains of Nepal. We coproduced the engagement approach with 40 artists from the Janakpur Women's Development Centre to create an environment for dialogue about diabetes and NCD risk between artists and the general public. Methods: We used participatory action research to produce contextually relevant interactive methods and materials. Methods included artists' peer research to inform creative workshops, a drama performed in 19 villages and a two-day funfair in a public park. We used qualitative and participatory methods to analyse the effect of this engagement and reflect on lessons learned. Results: Around 2000 people saw the drama, and around 4000 people attended the funfair. Community dialogue about prevention of diabetes was facilitated by drama and through games and songs at the funfair. Artists grew confident to interact with their peers and drama audiences about the causes of diabetes and prevention strategies. Despite crowds at the funfair, it was difficult to reach women because the venue was often used by men and boys, and patriarchal norms prevent women from free movement. Village interactions were able to engage a more mixed audience. Conclusion: Innovative, asset-based community engagement about diabetes and other NCDs at scale is possible through locating, building on and strengthening community resources to address local health issues. Engagement could be enhanced by considering the gendered nature of community engagement spaces and by increasing opportunities for interaction between artists and the general public through more intimate and large-scale events.

+1405,Article,A novel workflow utilizing open-source software tools in the environmental fate studies: The example of imatinib biotransformation,"The aim of this study is to utilize novel and powerful workflows with publicly available tools to efficiently process data and facilitate rapid acquisition of knowledge on environmental fate studies. Taking imatinib (IMA) as an example, we developed an efficient workflow to describe IMA biodegradation with activated sludge (AS) from wastewater treatment plants (WWTP). IMA is a cytostatic pharmaceutical; a selective tyrosine kinase inhibitor used to treat chronic myeloid leukemia. Its reported ecotoxic, endocrine and genotoxic effects imply high risk for aquatic wildlife and human health, however its fate in the environment is not yet well known. The study was conducted in a batch biotransformation setup, at two AS concentration levels and in presence and absence of carbon source. Degradation profiles and formation of IMA transformation products (TPs) were investigated using UHPLC-QqOrbitrap-MS/MS which showed that IMA is readily biodegradable. TPs were determined using multivariate statistical analysis. Eight TPs were determined and tentatively identified, six of them for first time. Hydrolysis of amide bond, oxidation, demethylation, deamination, acetylation and succinylation are proposed as major biodegradation pathways. TP235, the product of amide bond hydrolysis, was detected and quantified in actual wastewaters, at levels around 1 ng/L. This calls for more studies on the environmental fate of IMA in order to properly asses the environmental risk and hazard associated to IMA and its TPs. (c) 2021 The Authors.

Using a conventional protocol to fabricate IHS from casts of the initial situation or the wax-up can be challenging, time-consuming, and sometimes frustrating. A digital workflow makes this process quicker and more convenient. The IHS must be first designed with computer-aided design (CAD), then fabricated with computer-aided manufacture (CAM). Proprietary dental software is commonly used for the design process but needs to be purchased. Objective: To describe a step-by-step technique for designing an IHS for posterior relining with open-source software. Methods: This paper describes a straightforward procedure to design an IHS from a dental scan of the initial situation or a digital wax-up for an esthetic and functional temporary rehabilitation. Results: An IHS can be quickly designed using open-source software by copying an existing restoration or a conventional or digital wax-up. Then, the design can be 3D printed using a biocompatible resin. Conclusions: The clinician can use open-source software to design IHSs, which are then 3D printed using a biocompatible resin. Clinical relevance: The clinician can design IHSs from a dental scan of the initial situation or a wax-up using opensource software by following the step-by-step protocol outlined in this paper. The restoration can then be 3D printed using a biocompatible resin.",10.1016/j.jdent.2021.103796

Artificial intelligence techniques such as deep neural networks and computer vision were trained to detect fission surface semi-tracks on images. The deep neural networks can be used in an open-source computer program for semi-automated fission track dating called ``AI-Track-tive{''}. Our custom-trained deep neural networks use the YOLOv3 object detection algorithm, which is currently one of the most powerful and fastest object recognition algorithms. The developed program successfully finds most of the fission tracks in the microscope images; however, the user still needs to supervise the automatic counting. The presented deep neural networks have high precision for apatite (97 \\%) and mica (98 \\%). Recall values are lower for apatite (86 \\%) than for mica (91 \\%).

We examine the characteristics of fuzzer-found faults, the lifecycles of such faults, and the evolution of fuzzing campaigns over time. We find that OSS-Fuzz is often effective at quickly finding bugs, and developers are often quick to patch them. However, flaky bugs, timeouts, and out of memory errors are problematic, people rarely file CVEs for security vulnerabilities, and fuzzing campaigns often exhibit punctuated equilibria, where developers might be surprised by large spikes in bugs found.

+1412,InProceedings,Analyzing and Detecting Emerging Quality-Related Concerns across OSS Defect Report Summaries,"Quality-related concerns are often coined with the terms non-functional requirements, architecturally significant requirements, and quality attributes. Collectively, these qualities affect non-behavioral concerns of the software system such as reliability, usability, security, or maintainability among others. As a byproduct of a long-term maintenance effort, these system qualities tend to erode over time, causing system-wide failures that emerge via quality-related bugs. Quality-related bugs can have a detrimental impact on system's sustained stability and can chiefly hinder its core functionality. Typically, for the developers, to manually examine these high-impacted quality-related bugs can become prohibitively expensive and impractical task to attain. This is often a case with bugs that are reported from medium or large-sized projects such as Eclipse. To alleviate this problem, we built a quality-based classifier to automatically detect these emerging quality-related concerns from textual descriptions of bug report summaries. Specifically, we leveraged a weighted combination of semantics, lexical, and shallow features in conjunction with the Random Forest ensemble learning method. Finally, we discuss the practical applicability of our classifier for mapping and visualizing quality-related concerns into the codebase with an example from the Derby project. To summarize, this work represents an effort and an early awareness to improve the underlying management of issue tracking systems and stakeholder requirements in open-source communities.",10.1109/SANER50967.2021.00011

Many open source software products are used to access and navigate through the Dark Web. Together they form the Dark Web open source software ecosystem. Research on this ecosystem is scarce and research on the ecosystem health is non-existent, even though ecosystem health is an useful indicator of the livelihood of an ecosystem. The goal of this research is to evaluate the health of the ecosystem through an assessment of Tor, I2P and GitHub. The Open Source Ecosystem Health Operationalization framework is used to help perform this assessment. Eight metrics from the framework are selected, which are measured using the data collected. Analysis of Tor and I2P metrics suggest that there has been an increase in Tor and I2P user activity in the recent past. Added knowledge, spin offs and forks and usage indicate active participation and interest in Tor and I2P. There has also been an increase in the number of active GitHub Dark Web projects. However, these GitHub projects are not well-connected and only a small number of projects have a large number of contributors. There is some variety among the GitHub software projects.

Our hackathon project aims to facilitate the understanding of the developer collaboration structure and relationships among projects based on the bi-graph of what projects developers contribute to by providing an interactive collaboration graph of this ecosystem, using the data obtained from World of Code {[}1] infrastructure. Our attempts to visualize the entirety of projects and developers were stymied by the inability of the layout and visualization tools to process the exceedingly large scale of the full graph. We used WoC to filter the nodes (developers and projects) and edges (developer contributions to a project) to reduce the scale of the graph that made it amenable to an interactive visualization and published the resulting visualizations.

+1418,Article,CRIMSON: An open-source software framework for cardiovascular integrated modelling and simulation,"In this work, we describe the CRIMSON (CardiovasculaR Integrated Modelling and SimulatiON) software environment. CRIMSON provides a powerful, customizable and user-friendly system for performing three-dimensional and reduced-order computational haemodynamics studies via a pipeline which involves: 1) segmenting vascular structures from medical images; 2) constructing analytic arterial and venous geometric models; 3) performing finite element mesh generation; 4) designing, and 5) applying boundary conditions; 6) running incompressible Navier-Stokes simulations of blood flow with fluid-structure interaction capabilities; and 7) post-processing and visualizing the results, including velocity, pressure and wall shear stress fields. A key aim of CRIMSON is to create a software environment that makes powerful computational haemodynamics tools accessible to a wide audience, including clinicians and students, both within our research laboratories and throughout the community. The overall philosophy is to leverage best-in-class open source standards for medical image processing, parallel flow computation, geometric solid modelling, data assimilation, and mesh generation. It is actively used by researchers in Europe, North and South America, Asia, and Australia. It has been applied to numerous clinical problems; we illustrate applications of CRIMSON to real-world problems using examples ranging from pre-operative surgical planning to medical device design optimization. Author summary We provide the first full presentation in the literature of CRIMSON, the Cardiovascular Integrated Modelling and Simulation Package. CRIMSON consists of a graphical user interface desktop computer program for creating geometric models of blood vessels from medical imaging scans, specifying parameters such as the stiffness of the artery walls, the resistance of connected vessels which are not visible on the scans, and determining the appropriate parameters for all aspects of the model. CRIMSON additionally consists of the Flowsolver, a high-performance computing package which simulates the flow of blood through the models created in the graphical user interface. Whilst several packages which can simulate blood flow exist, most target general fluid simulations, and this lack of specialisation means that blood flow simulation is harder to perform, and can require ad hoc (and potentially scientifically-limiting) workflow decisions. CRIMSON's specialisation deals with these problems, as well as presenting a number of unique features which are unavailable elsewhere.",10.1371/journal.pcbi.1008881

The software is based on identifying representative donor/acceptor geometries within interfacial structures obtained from molecular dynamics simulation of donor/acceptor blends and calculating the corresponding Fermi's golden rule CT rate constants within the framework of the linearized-semiclassical approximation. While the methods used are well established, the integration of these state-of-the-art tools originating from different disciplines to study photoinduced CT processes with explicit treatment of the environment, in our opinion, makes this package unique and innovative. The software also provides tools for investigating other observables of interest. After outlining the features and implementation details, the usage and performance of the software are demonstrated with results from an example OPV system.",10.1063/5.0050574

In this context, the present study has analyzed the factors that incentivize OSS implementations for enterprise purposes, linking two perspectives: (1) managerial and (2) educational. Thus, the Delphi methodology was applied to a panel of experts with two aims: (1) to know managers' perceptions about organizational users' motivations toward OSS after receiving OSS training and (2) to develop a forecasting study to examine the OSS diffusion in the medium term in companies and educational centers. In this context, the Self-Determination Theory (SDT) was the theoretical approach through which we identified the motivational factors. Specifically, three SDT motivations were added: (1) autonomy, (2) competence and (3) relatedness. The 104 selected experts were managers from companies with employees who have studied in educational centers where OSS usage is mandatory. The results show that managers perceive that OSS training incentivizes OSS implementations in companies. At the same time, user motivations are considered to be extremely relevant, especially autonomy. In addition, is the results foresee a similar level of OSS implementation in the business and educational fields in the medium term. Finally, conclusions, practical implications and limitations are discussed.",10.3390/electronics10030277
+1421,Article,"CiliaQ: a simple, open-source software for automated quantification of ciliary morphology and fluorescence in 2D, 3D, and 4D images","Cilia are hair-like membrane protrusions that emanate from the surface of most vertebrate cells and are classified into motile and primary cilia. Motile cilia move fluid flow or propel cells, while also fulfill sensory functions. Primary cilia are immotile and act as a cellular antenna, translating environmental cues into cellular responses. Ciliary dysfunction leads to severe diseases, commonly termed ciliopathies. The molecular details underlying ciliopathies and ciliary function are, however, not well understood. Since cilia are small subcellular compartments, imaging-based approaches have been used to study them. However, tools to comprehensively analyze images are lacking. Automatic analysis approaches require commercial software and are limited to 2D analysis and only a few parameters. The widely used manual analysis approaches are time consuming, user-biased, and difficult to compare. Here, we present CiliaQ, a package of open-source, freely available, and easy-to-use ImageJ plugins. CiliaQ allows high-throughput analysis of 2D and 3D, static or time-lapse images from fluorescence microscopy of cilia in cell culture or tissues, and outputs a comprehensive list of parameters for ciliary morphology, length, bending, orientation, and fluorescence intensity, making it broadly applicable. We envision CiliaQ as a resource and platform for reproducible and comprehensive analysis of ciliary function in health and disease.",10.1140/epje/s10189-021-00031-y
+1422,Article,Clinica: An Open-Source Software Platform for Reproducible Clinical Neuroscience Studies,"We present Clinica ((www.clinica.run), an open-source software platform designed to make clinical neuroscience studies easier and more reproducible. Clinica aims for researchers to (i) spend less time on data management and processing, (ii) perform reproducible evaluations of their methods, and (iii) easily share data and results within their institution and with external collaborators. The core of Clinica is a set of automatic pipelines for processing and analysis of multimodal neuroimaging data (currently, T1-weighted MRI, diffusion MRI, and PET data), as well as tools for statistics, machine learning, and deep learning. It relies on the brain imaging data structure (BIDS) for the organization of raw neuroimaging datasets and on established tools written by the community to build its pipelines. It also provides converters of public neuroimaging datasets to BIDS (currently ADNI, AIBL, OASIS, and NIFD). Processed data include image-valued scalar fields (e.g., tissue probability maps), meshes, surface-based scalar fields (e.g., cortical thickness maps), or scalar outputs (e.g., regional averages). These data follow the ClinicA Processed Structure (CAPS) format which shares the same philosophy as BIDS. Consistent organization of raw and processed neuroimaging files facilitates the execution of single pipelines and of sequences of pipelines, as well as the integration of processed data into statistics or machine learning frameworks. The target audience of Clinica is neuroscientists or clinicians conducting clinical neuroscience studies involving multimodal imaging, and researchers developing advanced machine learning algorithms applied to neuroimaging data.",10.3389/fninf.2021.689675

Methods Medical records of Department of Oral and Maxillofacial Surgery of Shandong Provincial Hospital were screened for patients who had been treated with immediate implant implantation in the esthetic area using either MC (Allgens (R), Beijing Allgens Medical Science and Technology Co., Ltd., China) or Bio-Oss (Bio-Oss (R), Geistlich Biomaterials, Wolhusen, Switzerland), between January 2018 and December 2019. All patients fulfilling the in-/exclusion criteria and following followed for a minimum period of 1 year after surgery were enrolled into the presented study. Implant survival rate, radiographic, esthetic and patient satisfactory evaluations were performed. Results Altogether, 70 patients were included in the study; a total of 80 implants were inserted. All implants had good initial stability. The survival rate of implants was 100\\% at 1-year follow-up. The differences in horizontal and vertical bone loss between the MC group (0.72 +/- 0.26 mm, 1.62 +/- 0.84 mm) and the Bio-Oss group (0.70 +/- 0.52 mm, 1.57 +/- 0.88 mm) were no significant difference statistically no significant 6 months after permanent restoration. Similar results occurred at 12 months after permanent restoration functional loaded. Clinical acceptability defined by pink esthetic score (PES) >= 6 (6.07 +/- 1.62 vs. 6.13 +/- 1.41) was not significantly different between groups. Patient satisfaction estimated by visual analog scale (VAS) was similar (8.56 +/- 1.12 vs. 8.27 +/- 1.44), and the difference was no significant difference between the two groups. Conclusions The biomimetic MC showed a similar behaviour as Bio-Oss not only in its dimensional tissues changes but also in clinical acceptability and patient satisfaction. Within the limitations of this study, these cases show that MC could be considered as an alternative bone graft in IIP",10.1186/s12903-021-01752-4
+1424,Article,Code of Conduct Conversations in Open Source Software Projects on Github,"The rapid growth of open source software necessitates a deeper understanding of moderation and governance methods currently used within these projects. The code of conduct, a set of rules articulating standard behavior and responsibilities for participation within a community, is becoming an increasingly common policy document in open source software projects for setting project norms of behavior and discouraging negative or harassing comments and conversation. This study describes the conversations around adopting and crafting a code of conduct as well as those utilizing code of conduct for community governance. We conduct a qualitative analysis of a random sample of GitHub issues that involve the code of conduct. We find that codes of conduct are used both proactively and reactively to govern community behavior in project issues. Oftentimes, the initial addition of a code of conduct does not involve much community participation and input. However, a controversial moderation act is capable of inciting mass community feedback and backlash. Project maintainers balance the tension between disciplining potentially offensive forms of speech and encouraging broad and inclusive participation. These results have implications for the design of inclusive and effective governance practices for open source software communities.",10.1145/3449093
+1425,Article,"Combining Multiband Imaging, Photogrammetric Techniques, and FOSS GIS for Affordable Degradation Mapping of Stone Monuments","The detailed documentation of degradation constitutes a fundamental step for weathering diagnosis and, consequently, for successful planning and implementation of conservation measures for stone heritage. Mapping the surface patterns of stone is a non-destructive procedure critical for the qualitative and quantitative rating of the preservation state. Furthermore, mapping is employed for the annotation of weathering categories and the calculation of damage indexes. However, it is often a time-consuming task, which is conducted manually. Thus, practical methods need to be developed to automatize degradation mapping without significantly increasing the diagnostic process's cost for conservation specialists. This work aims to develop and evaluate a methodology based on affordable close-range sensing techniques, image processing, and free and open source software for the spatial description, annotation, qualitative analysis, and rating of stone weathering-induced damage. Low-cost cameras were used to record images in the visible, near-infrared, and thermal-infrared spectra. The application of photogrammetric techniques allowed for the generation of the necessary background, that was elaborated to extract thematic information. Digital image processing of the spatially and radiometrically corrected images and image mosaics enabled the straightforward transition to a spatial information environment simplifying the development of degradation maps. The digital thematic maps facilitated the rating of stone damage and the extraction of useful statistical data.",10.3390/buildings11070304

Following a recent trend in the cartographic community towards using Blender, we tried to improve the standard relief visualization in common GIS software by blending it with a shaded relief rendered in Blender. Using different QGIS blending modes and opacity values we achieved different graphic visualizations. To compare and evaluate the suitability of different rendering techniques we chose national park Risnjak located in Croatia because of its specific and diverse terrain landforms. After comparing different input layers and parameter sets, we selected the blending combination which is best suited for visualizing terrain characteristics of all Croatian national parks. The result is a shaded relief created for every national park which is combined from a shaded relief rendered in Blender, a hillshade created in QGIS, a hypsometric coloured DEM and a draped digital orthophoto.",10.5194/ica-proc-4-111-2021
+1428,Article,Companies' Participation in OSS Development-An Empirical Study of OpenStack,"Commercial participation continues to grow in open source software (OSS) projects and novel arrangements appear to emerge in company-dominated projects and ecosystems. What is the nature of these novel arrangements? Does volunteers' participation remain critical for these ecosystems? Despite extensive research on commercial participation in OSS, the exact nature and extent of company contributions to OSS development, and the impact of this engagement may have on the volunteer community have not been clarified. To bridge the gap, we perform an exploratory study of OpenStack: a large OSS ecosystem with intense commercial participation. We quantify companies' contributions via the developers that they provide and the commits made by those developers. We find that companies made far more contributions than volunteers and the distribution of the contributions made by different companies is also highly unbalanced. We observe eight unique contribution models based on companies' commercial objectives and characterize each model according to three dimensions: contribution intensity, extent, and focus. Companies providing full cloud solutions tend to make both intensive (more than other companies) and extensive (involving a wider variety of projects) contributions. Usage-oriented companies make extensive but less intense contributions. Companies driven by particular business needs focus their contributions on the specific projects addressing these needs. Minor contributors include community players (e.g., the Linux Foundation) and research groups. A model relating the number of volunteers to the diversity of contribution shows a strong positive association between them.",10.1109/TSE.2019.2946156
+1430,Article,Comparison of the performances of low-crystalline carbonate apatite and Bio-Oss in sinus augmentation using three-dimensional image analysis,"Background In locations where the alveolar bone height is low, such as at the maxillary molars, implant placement can be difficult, or even impossible, without procedures aimed at generating new bone, such as sinus lifts. Various types of bone graft materials are used after a sinus lift. In our study, a three-dimensional image analysis using a volume analyzer was performed to measure and compare the volume of demineralized bovine bone mineral (Bio-Oss (R)) and carbonate apatite (Cytrans (R)) after a sinus lift, as well as the amount of bone graft material resorption. Patient data were collected from cone-beam computed tomography images taken before, immediately following, and 6 months after the sinus lift. Using these images, both the volume and amount of resorption of each bone graft material were measured using a three-dimensional image analysis system. Results The amount of bone resorption in the Bio-Oss (R)-treated group was 25.2\\%, whereas that of the Cytrans (R)-treated group was 14.2\\%. A significant difference was found between the two groups (P < 0.001). Conclusions Our findings indicate that the volume of bone resorption was smaller in the Cytrans (R)-treated group than in the Bio-Oss (R)-treated group, suggesting that Cytrans (R) is more promising for successful implant treatments requiring a sinus lift.",10.1186/s40729-021-00303-4
+1431,Article,Competition Among Proprietary and Open-Source Software Firms: The Role of Licensing in Strategic Contribution,"In enterprise software markets, firms are increasingly using services-based business models built on open-source software (OSS) to compete with established, proprietary software firms. Because third-party firms can also strategically contribute to OSS and compete in the services market, the nature of competition between OSS constituents and proprietary software firms can be complex. Moreover, their incentives are likely influenced by the licensing schemes that govern OSS. We study a three-player game and examine how open-source licensing affects competition among an open-source originator, an open-source contributor, and a proprietor competing in an enterprise software market. In this regard, we examine (1) how quality investments and prices are endogenously determined in equilibrium, (2) how license restrictiveness impacts equilibrium investments and the quality of offerings, and (3) how license restrictiveness affects consumer surplus and social welfare. Although some in the open-source community often advocate restrictive licenses such as theGNUGeneral Public License because it is not always in the best interest of the originator for the contributor to invest greater development effort, such licensing can actually be detrimental to both consumer surplus and social welfare when it exacerbates this incentive conflict. We find such an outcome in markets characterized by software providers with similar development capabilities yet cast in favor of the proprietor. In contrast, when these capabilities either become more dispersed or remain similar but tilt in favor of open source, a more restrictive license instead encourages greater effort from the OSS contributor, leads to higher OSS quality, and provides a larger societal benefit.",10.1287/mnsc.2020.3674
+1433,Article,DBscorer: An Open-Source Software for Automated Accurate Analysis of Rodent Behavior in Forced Swim Test and Tail Suspension Test,"Forced swim test (FST) and tail suspension test (TST) are commonly used behavioral tests for screening antidepressant drugs with a high predictive validity. These tests have also proved useful to assess the non-motor symptoms in the animal models of movement disorders such as Parkinson's disease and Huntington's disease. Manual analysis of FST and TST is a time-consuming exercise and has large observer-to-observer variability. Automation of behavioral analysis alleviates these concerns, but there are no easy-to-use open-source tools for such analysis. Here, we describe the development of Depression Behavior Scorer (DBscorer), an open-source program installable on Windows, with an intuitive graphical user interface (GUI), that helps in accurate quantification of immobility behavior in FST and TST from video analysis. Several calibration options allow customization of various parameters to suit the experimental requirements. Apart from the readout of time spent immobile, DBscorer also provides additional data and graphics of immobility/mobility states across time revealing the evolution of behavioral despair over the duration of the test and allows the analysis of additional parameters. Such comprehensive analysis allows a more nuanced understanding of the expression of behavioral despair in FST and TST. We believe that DBscorer would make analysis of behavior in FST and TST unbiased, automated and rapid, and hence prove to be helpful to the wider neuroscience community.",10.1523/ENEURO.0305-21.2021

We demonstrate its successful application for segmentation of 2D and 3D electron and multicolor light microscopy datasets with isotropic and anisotropic voxels. We distribute DeepMIB as both an open-source multi-platform Matlab code and as compiled standalone application for Windows, MacOS and Linux. It comes in a single package that is simple to install and use as it does not require knowledge of programming. DeepMIB is suitable for everyone interested of bringing a power of deep learning into own image segmentation workflows. Author summary Deep learning approaches are highly sought after solutions for coping with large amounts of collected datasets and are expected to become an essential part of imaging workflows. However, in most cases, deep learning is still considered as a complex task that only image analysis experts can master.

The ADC can record a temporal signal produced by chromatography and flow-injection analysis. It has two voltage measurement ranges: +/- 2.048 V and +/- 1.024 V, respectively, with 14-bit resolution and a four samples s(-1) sampling rate. The voltage resolution is 0.25 mV and 0.125 mV per one ADC reading for +/- 2.048 V and +/- 1.024 V, respectively. Its dimensions were 100x70x30 mm, and mass was 110 g. We have evaluated its performance, including the linearity and the difference between the two devices. For +/- 1.024 V range, the calibration curve for one ADC and another was D = 7954V 5 and D = 7946V + 30, respectively, where D is an ADC reading, and V is an input voltage. For another range, it was D = 3972V - 3 and D = 3968V + 15, respectively. Their slopes and intercept agreed with each other, and had good linearity, R-2 > 0.9999.

India is the largest consumer of water, with an estimated usage of around 300 cubic kilometers per year. Punjab, a north-western state of India, is an example of severe crises aquifer depletion due to unconstrained consumption of groundwater, leading to degradation of its quantity as well as quality. Thus it is of great importance to compile up-to-date information about the water requirement for its appropriate and sustainable use. Remote sensing and geographic information system (GIS) are the technologies that can provide efficient and effective information system to tackle the water quality \\& water supply planning parameters. Thus, under the present study, a web-enabled water resource information system has been developed in the GIS environment for the SAS (Sahibzada Ajit Singh) Nagar and Patiala districts of Punjab by using the open source software MS4W and pmapper. This system provides digital information of natural, such as drainage, and man-made features like roads, canals, and tube wells with their location and so on, and also provide information related to water level, water quality of wells, and well depth for the study area. Such an information system can be very helpful for the administrators and can serve as a decision support system for planners and policy makers so that the areas where problems related to water quality can be identified and focused upon.

+1440,Article,Differential impacts of social influence on initial and sustained participation in open source software projects,"Social networking tools and visible information about developer activities on open source software (OSS) development platforms can leverage developers' social influence to attract more participation from their peers. However, the differential impacts of such social influence on developers' initial and sustained participation behaviors were largely overlooked in previous research. We empirically studied the impacts of two social influence mechanisms-word-of-mouth (WOM) and observational learning (OL)-on these two types of participation, using data collected from a large OSS development platform called Open Hub. We found that action (OL) speaks louder than words (WOM) with regard to sustained participation. Moreover, project age positively moderates the impacts of social influence on both types of participation. For projects with a higher average workload, the impacts of OL are reduced on initial participation but are increased on sustained participation. Our study provides a better understanding of how social influence affects OSS developers' participation behaviors. It also offers important practical implications for designing software development platforms that can leverage social influence to attract more initial and sustained participation.",10.1002/asi.24481

OSS developers create links among development units (e.g. issues and pull requests in GitHub), share their opinions and promote the resolution of development units. Although previous work has examined the role of links in recommending high-priority tasks and reducing resource waste, the understanding of the actual usage of links in practice is still limited. To address the research gap, we conduct an empirical study based on the 5W1H model and data mining from five popular OSS projects on GitHub. We find that links originating from a PR are more common than the other three types of links, and links are more frequently created in Documentation. We also find that average duration between development units' create time in a link is half a year. We observed that link behaviors are very complex and the duration of link increases with the complexity of link structure. We also observe that the reasons of link are very different, especially in P-P and I-I. Finally, future works are discussed in conclusion.",10.1142/S0218194021500388
+1445,Article,Environmental Desire in: The Mill on the Floss,"This essay argues that George Eliot's expansive use of landscape description in The Mill on the Floss (1860) represents an engagement with the emerging concept of a biological ``medium{''} or ``environment{''} in the nineteenth-century sciences. In the 1850s, scientific writers including Auguste Comte, Herbert Spencer, and G. H. Lewes redefined biological life as dependent on an abstraction called a ``medium{''} or ``environment{''}- a term that united all the objects, substances, and forces in an organism's physical surroundings into a singular entity. Eliot in The Mill on the Floss draws out the ecological potential of this new biological concept by imbuing the described backgrounds of her novel with a lyrical affect I call ``environmental desire,{''} a diffuse longing for ambient contact with one's formative medium that offers an ethical alternative to the possessive and object-driven forms of desire that drive the plot of a traditional Bildungsroman. Maggie Tulliver's marriage plot is structured by a tension between environmental desire and possessive desire, in which her erotic desire for Stephen Guest competes with a more diffuse environmental desire that attaches to the novel's described backgrounds. Ultimately, the new environment concept enables Eliot to reconceive the Bildungsroman's usual opposition between self and world as a relationship of nourishment and dependency rather than struggle, and invites a reconsideration of the ecological role of description in the Bildungsroman genre.",10.1525/ncl.2021.76.2.192
+1446,Article,Episodic Peripheral Contributors and Technical Dependencies in Open Source Software (OSS) Ecosystems,"Despite the fact that OSS contributors tend to eschew traditional organizational hierarchies, researchers have found that, in many cases, OSS contributors make tightly coupled system designs and successfully coordinate highly interdependent tasks. Although researchers have explained how OSS contributors make tightly coupled code contributions, we do not know the characteristics of individuals who make such contributions. While previous studies have considered OSS projects as single, independent containers, I note that OSS projects do not constitute independent or standalone entities but reuse and, thus, depend one another. This reuse creates complex networks of interdependencies called ``software ecosystems{''}. In this paper, I analyze OSS contributors who have made tightly coupled code contributions using two lenses: the core-periphery lens and the habitual-episodic lens. Based on investigating three volunteer-driven OSS projects, I found OSS contributors who make tightly coupled code contributions to have different code-contribution patterns. Interestingly, I found that half of such contributors made no previous code contributions to the sampled projects but episodically authored patches (or pull requests) that increased software coupling. Based on further investigation, I suggest a multiple-fluid-container view that accommodates software ecosystems in which multiple containers (multiple OSS projects) co-evolve with each container (each OSS project) readily accessible.",10.17705/1CAIS.04908
+1450,InProceedings,Estimating the Attack Surface from Residual Vulnerabilities in Open Source Software Supply Chain,"Software supply chain security has now become a critical concern in the software industry (and beyond) following the large impact of recent attacks: hackers injected malicious code into Solarwinds components and Octopus scanner, which eventually infected a wide range of downstream dependencies, affecting a massive number of users. Since supply chain vulnerabilities are a well-known concern, especially with open source systems, approaches in the literature mainly focus on identifying and patching such vulnerability. Frequently, however, a vulnerability patch is not immediately propagated to earlier releases that have been inherited by dependents, leaving residual vulnerabilities in supply chains. Our work addresses this challenge and develops a simple approach to iteratively explore the attack surface of supply chain residual vulnerabilities in open source projects. We have assessed our search scheme on 50 GitHub-hosted projects having high stars and forks: we mine their bug fix commits and identify buggy package versions to track the affected dependents and estimate the potential attack surface. We find that many projects fix their vulnerable issues by update their dependency versions, and version inheritance is a significant cause of supply chain attacks for open source projects.",10.1109/QRS54544.2021.00060

Here the generated electricity outputs data of the photovoltaics (PVs), installed on the building rooftops at the Indian Institute of Technology (IIT) Roorkee, India, have been obtained from the Institute for the past four years (2015-18). Simultaneously, the solar PV output data have been predicted using open source software application, geographic information system (GIS), Perl, global horizontal irradiance (GHI), remote sensing, and cloud computing. The satellite-derived GHI has been obtained from the database developed by the National Renewable Energy Laboratory (NREL), United States, and local GHI using a pyranometer to validate the results. In the presented work, tilted GHI has been estimated using modified tilt angle algorithm implemented using Perl in a cloud environment. Further, the usable rooftop area has been digitized on high-resolution WorldView-3 image and calculated using QGIS. In this study, the validation of an optimum tilt angle has been performed by the comparison of the output from the installed solar plant to the predicted solar potential. The processing of optimum tilt angle obtained (19.86 degrees) at IIT Roorkee has been performed using XenCenter server. This helped in processing the computation-intensive tilted GHI at various tilt angles. This approach also helped in providing further expansion plan.

The primary developers start and administer an OSS project. However, they do not manage those who contribute. The literature shows that 80\\% of issues are resolved by 20\\% of developers when developing an OSS. Therefore, identifying influential developer communities is quite necessary for OSS stakeholders to reduce the efforts required to solve the issue through releases and predict quality. The purpose of this proposed empirical study is to explore influential communities by analyzing the relationship between their members as an OSS evolves and its impact on software quality. We performed several experiments with releases of three widely used OSS, namely ?BIGDL,? ?INCUBATOR-MXNET? and ?RECOMMENDERS.? The major implications of the proposed study include; 1) The community development structure is not centralized and controlled, 2) Influential communities were observed in early releases of an OSS, 3) There is no guarantee of an influential community in the consecutive releases, 4) Notable developers are varied through the releases, and 5) The presence of influential communities in subsequent releases could lead to the maturity of an OSS.",10.32604/iasc.2021.015034

Unfortunately, there is Pareto principle in OSSD projects, and a large number of OSSD projects have little influence, many projects a re unable to attract user interest. Therefore, it is important to understand the factors affecting OSSD project success as measured by project popularity. While technical factors such as license and compatibility with certain operating systems have a direct influence on the popularity of OSSD projects, development-related factors also have latent impacts on the popularity of OSSD projects. Therefore, we collect data on 445 projects and successfully build a structural equation model (SEM) which depicts the inherent relationships between development-related factors and OSSD project popularity.

Objective: This work is aimed at studying the communication functions of bug comments and their associations with fast and complete bug fixing in OSS development. Method: Over 500K comments and 89K bugs of 100 OSS projects were extracted from three Issue Tracking Systems. Six thousand comments were manually tagged to create a corpus of communication functions. The extracted comments were automatically tagged using machine learning algorithms and the corpus of communication functions. Statistical and correlation analyses were performed and the most frequent comments communicated during fast and successful bug fixing were identified. Results: Significant differences in the distribution of comments of fixed and not fixed bugs were found. Variations in the distribution of comments of bugs with different fixing time were also found. Referential comments that provided objective information were found to be the most frequent messages. Results showed that the percentages of conative and emotive comments are greater when bugs are resolved without the requested fixes and when fixes are implemented in a long time. Conclusion: Associations between communication functions and bug fixing exist. The results of this work could be used to improve corrective tasks in OSS development and some other specific linguistic aspects should be studied in detail in OSS communities.",10.1016/j.infsof.2021.106584
+1457,Article,Exploring the link between free and open source software and the collaborative economy: A Delphi-based scenario for the year 2025,"Despite the growth experienced by the Collaborative Economy in recent years, there are still unexplored gaps within this phenomenon. One of the areas of study with scarce literature is linked with the impact of the In-formation and Communication Technologies based on collaborative environments, such as Free and Open Source Software, on the spread of the Collaborative Economy. Some questions are raised, such as: (1) To what extent do organizations linked with Collaborative Economy make use of Free and Open Source Software?, (2) What are the incentives that motivate the implementation of Free and Open Source Software in Collaborative Economy companies?, (3) What use do Collaborative Economy companies give to Free and Open Source Software?, and (4) Is there a greater use of Free and Open Source Software expected for the coming years among these organiza-tions? To answer these questions, a study based on the Delphi method has been designed. To this end, a panel of 15 high-level experts in the field was formed. From the consensus of the experts, a significant role for Free and Open Source Software in the different collaborative components and industries is evident, with the current levels practically being maintained by the year 2025.",10.1016/j.techfore.2021.121087
+1460,InProceedings,Extracting Rationale for Open Source Software Development Decisions - A Study of Python Email Archives,"A sound Decision-Making (DM) process is key to the successful governance of software projects. In many Open Source Softoware Development (OSSD) communities, DM processes lie buried amongst vast amounts of publicly available data. Hidden within this data lie the rationale for decisions that led to the evolution and maintenance of software products. While there have been some efforts to extract DM processes from publicly available data, the rationale behind `boo' the decisions are made have seldom been explored. Extracting the rationale for these decisions can facilitate transparency (by making them known), and also promote accountability on the part of decision-makers. This work bridges this gap by means of a large-scale study that unearths the rationale behind decisions from Python development email archives comprising about 1.5 million mails. This paper makes two main contributions. First. it makes a knowledge contribution by unearthing and presenting the rationale behind decisions made. Second. it makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs multiple heuristics, and follows a data-driven. bottom-up approach to infer the rationale behind specific decisions (e.g., whether a new module is implemented based on core developer consensus or benevolent dictator's pronouncement). Our approach can be applied to extract rationale in other OSSD communities that have similar governance structures.",10.1109/ICSE43902.2021.00095
+1463,Article,Flourish or Perish? The Impact of Technological Acquisitions on Contributions to Open-Source Software,"This study examines the impact of technological acquisitions on contributions to firm-sponsored community-based open-source software (OSS). We distinguish between internal contributors affiliated with target firms and external contributors from the community, and examine how they respond to technological acquisitions differently. Theoretically, we examine how technological acquisition influences contributors' uncertainty about project quality through a signaling effect and influences their uncertainty about project continuity through potential resource combination. We connect uncertainties with contributors' motivations to theorize their responses to acquisitions. Empirically, we find that external contributors contribute more actively to both target firms' sponsored projects and other projects in the OSS community after acquisitions, which contrast with the adverse effects of acquisitions observed in traditional corporate innovation. Although internal contributors reduce contributions to target firms' sponsored projects after acquisitions, they increase contributions to other OSS projects in the community. We also find that the acquirer's OSS experience and the project similarity between the acquirer and the target drive both external and internal contributors to shift their development efforts to the acquirer's projects and other projects in the OSS community. By examining these effort shifts in OSS contributions, our study generates unique theoretical insights about the impacts of technological acquisitions in the OSS context and important practical implications for acquirers, target firms, and the general OSS community.",10.1287/isre.2021.1086

This paper measures up to 21 years of activities in 1314 individual projects and 1.4 billion lines of code managed. After analyzing the FOSS activities on the projects and organizations level, such as commits frequency, source code lines, and code comments, we find that there is less activity now than there was a decade ago. Moreover, our results suggest a greater decrease in the activities in large and well-established FOSS organizations. Our findings indicate that as technologies and business strategies related to FOSS mature, the role of large formal FOSS organizations serving as intermediary between developers diminishes.",10.1371/journal.pone.0257192

The End Point Rate for QGIS (EPR4Q) computes a coastline projection using the End Point Rate method. The Uncertainty Bathtub Model (uBTM) analyses the effects of sea-level rise through the uncertainty of sea-level projections and the vertical error of the Digital Elevation/Terrain Model. The Bruun Rule for Google Earth Engine Model (BRGM) predicts the position of the shoreline with sea-level rise, using topographic and bathymetric data from Unmanned Aerial Vehicles and Coastal Modeling System, respectively. Based on the regional projections of the Special Report on Climate Change and Oceans and Cryosphere of the Intergovernmental Panel on Climate Change, the models were applied to a study case on the coast of Rio Grande do Sul-Brazil under different scenarios of sea-level rise expected by the end of this century. The results showed a maximum coastal retreat for the year 2100 of -502 m and -1727 m using EPR4Q and BRGM, respectively. The uBTM with Mapbiomas land use showed a maximum of 44.57 km(2) of urban area affected by sea-level flooding.

+1468,Article,FullControl GCode Designer: Open-source software for unconstrained design in additive manufacturing,"A new concept is presented for the design of additive manufacturing procedures, which is implemented in opensource software called FullControl GCode Designer. In this new design approach, the user defines every segment of the print-path along with all printing parameters, which may be related to geometric and non-geometric factors, at all points along the print-path. Machine control code (GCode) is directly generated by the software, without the need for any programming skills and without using computer-aided design (CAD), STL-files or slicing software. Excel is used as the front end for the software, which is written in Visual Basic. Case studies are used to demonstrate the broad range of structures that can be designed using the software, including: precisely controlled specimens for printer calibration, parametric specimens for hardware characterisation utilising hundreds of unique parameter combinations, novel mathematically defined lattice structures, and previously inconceivable 3D geometries that are impossible for traditional slicing software to achieve. The FullControl design approach enables unconstrained freedom to create nonplanar 3D print-paths and break free from traditional restrictions of layerwise print-path planning. It also allows nozzle movements to be carefully designed both during extrusion and while travelling between disconnected extrusion volumes - to overcome inherent limitations of the printing process or to improve capabilities for challenging materials. An industrial case study shows how explicit print-path design improved printer reliability, production time, and print quality for a production run of over 1000 parts. FullControl GCode Designer offers a general framework for unconstrained design and is not limited to a particular type of structure or hardware; transferability to lasers and other manufacturing processes is discussed. Parametric design files use a few bytes or kilobytes of data to describe all details that are sent to the printer, which greatly improves shareability by eliminating any risk of errors being introduced during STL file conversion or due to different users having inconsistent slicer settings. Adjustable parameters allow GCode for revised designs to be produced instantly, instead of the laborious traditional routine using multiple software packages and file conversions. The FullControl design concept offers new opportunities for creative and high-precision use of additive manufacturing systems. It facilitates design for additive manufacturing (DfAM) at the smallest possible scale based on the fundamental nature of the process (i.e. assembly of individual extrusions). The software and source code are provided as supplementary data and ongoing updates to improve functionality and the user interface will be available at www.fullcontrolgcode.com.",10.1016/j.addma.2021.102109
+1469,Article,GREAT-UPD: An open-source software for uncalibrated phase delay estimation based on multi-GNSS and multi-frequency observations,"To meet the demands of precise orbit and clock determination, high-precision positioning, and navigation applications, a software called GREAT (GNSS + Research, Application and Teaching) was designed and developed at Wuhan University. As one important module in the GREAT software, GREAT-UPD was developed for multi-GNSS and multi-frequency uncalibrated phase delay (UPD) estimation. It can provide extra-wide-lane (EWL), wide-lane (WL), and narrow-lane (NL) UPDs for GPS, GLONASS, Galileo and BDS (GREC) satellites for precise point positioning (PPP) ambiguity resolution (AR) in a multi-GNSS and multi-frequency environment. The open-source GREAT-UPD software is written in C + + 11 language following object-oriented principles and can be compiled and run on several popular operating systems, such as Windows, Linux, and Macintosh. Observations from 222 stations spanning days from DOY 091 to 120 were used to conduct multi-GNSS and multi-frequency UPD estimation and PPP AR. Results indicate that GREAT-UPD can generate stable and reliable UPD products with multi-GNSS and multi-frequency observations. After applying the UPD corrections, the multi-frequency GREC PPP AR was achieved with the averaged time to first fix of 9.0 min. The software package can be obtained at https://geodesy.noaa. gov/gps-toolbox,, including the source code, user manual, batch processing scripts, example data, and some auxiliary tools.",10.1007/s10291-020-01070-2
+1470,Article,GenUI: interactive and extensible open source software platform for de novo molecular generation and cheminformatics,"Many contemporary cheminformatics methods, including computer-aided de novo drug design, hold promise to significantly accelerate and reduce the cost of drug discovery. Thanks to this attractive outlook, the field has thrived and in the past few years has seen an especially significant growth, mainly due to the emergence of novel methods based on deep neural networks. This growth is also apparent in the development of novel de novo drug design methods with many new generative algorithms now available. However, widespread adoption of new generative techniques in the fields like medicinal chemistry or chemical biology is still lagging behind the most recent developments. Upon taking a closer look, this fact is not surprising since in order to successfully integrate the most recent de novo drug design methods in existing processes and pipelines, a close collaboration between diverse groups of experimental and theoretical scientists needs to be established. Therefore, to accelerate the adoption of both modern and traditional de novo molecular generators, we developed Generator User Interface (GenUI), a software platform that makes it possible to integrate molecular generators within a feature-rich graphical user interface that is easy to use by experts of diverse backgrounds. GenUI is implemented as a web service and its interfaces offer access to cheminformatics tools for data preprocessing, model building, molecule generation, and interactive chemical space visualization. Moreover, the platform is easy to extend with customizable frontend React.js components and backend Python extensions. GenUI is open source and a recently developed de novo molecular generator, DrugEx, was integrated as a proof of principle. In this work, we present the architecture and implementation details of GenUI and discuss how it can facilitate collaboration in the disparate communities interested in de novo molecular generation and computer-aided drug discovery.",10.1186/s13321-021-00550-y
+1472,Article,Generating UAV high-resolution topographic data within a FOSS photogrammetric workflow using high-performance computing clusters,"Photogrammetry is one of the most reliable techniques to generate high-resolution topographic data and it is key to territorial mapping and change detection analysis of landforms in hydro-geomorphological high-risk areas. Specifically, the Structure from Motion (SfM) is an emerging topographic survey technique that addresses the problem of determining the 3D position of image descriptors to estimate three-dimensional structures. Thanks to the potential of SfM algorithm and the development of Unmanned Aerial Vehicles (UAVs) that allow the ondemand acquisition of high-resolution aerial images, it is possible to survey extended areas of the Earth surface and monitor active phenomena through multi-temporal surveys. However, the ability to detect remote and wide areas with a very high-resolution is countered by the need to capture large datasets which can limit the photogrammetric process, due to the need for high-performance hardware. This paper presents a photogrammetric workflow based on Free and Open-Source Software (FOSS), which is able to return different outputs and to manage a large amount of data in reasonable time, through the distribution of the most computationally expensive steps on computing clusters hosted by the ReCaS-Bari data center for scientific research. The results are given in terms of performance evaluations based on different computing configurations of the clusters and setups of the steps of the workflow. The HTC cluster test with a parallel SSH approach involved an important reduction of several hours in the processing time of thousands UAV images, especially compared to classic photogrammetric process on a single workstation with commercial software. A parallel test, aimed to validate the performance of a single sever of the new HPC cluster, involved really good results halving the processing time with respect to the HTC cluster test.",10.1016/j.jag.2021.102600

Thus, Global Navigation Satellite System Interferometric Reflectometry (GNSS-IR) has emerged as a new remote sensing technology for monitoring snow depth. We developed the snow parameter processing software GiRsnow, based on GNSS-IR tools and a MATLAB environment, to obtain robust and effective retrievals. That tool allows users to check the data quality, draw reflection point trajectory and Fresnel zone, retrieve snow depth using signal-to-noise ratio (SNR) observations or geometry-free linear carrier phase combination (termed L4) observations, and display the results based on the time and space domain. We conducted two experiments at the Plate Boundary Observation site RN86 and GPS Earth Observation Network (GEONET) site 020877 to validate the performance of the software. Our results demonstrate that GiRsnow can process multi-constellation and multi-frequency GNSS data and obtain robust and effective results through quality control and a grid model to account for topography effects.",10.1007/s10291-021-01096-0

The development of multiple chemical derivatization strategies and bioinformatic software is responsible for some of the greatest analytical gains in the field of glycomics. The INLIGHT strategy is a chemical derivatization technique using hydrazide chemistry to derivatize the reducing end of N-linked glycans and incorporates either a natural (NAT, C-12(6)) or a stable-isotope label (SIL, C-13(6)) to carry out relative quantification. Here we present GlycoHunter, a user-friendly software created in MATLAB that enables researchers to accurately and efficiently process MS1 glycomics data where a NAT and SIL pair is generated for relative quantification, including but not limited to, INLIGHT. GlycoHunter accepts the commonly used data file formats imzML and mzXML and effectively identifies all peak pairs associated with NAT- and SIL-labeled N-linked glycans using MS1 data.

In particular, there has been a surge in deep learning and computer vision techniques to analyse digital images. Common practice in this area is to use image pre-processing and augmentation to prevent bias and overfitting, creating a more robust deep learning model. This generally requires consultation of documentation for multiple coding libraries, as well as trial and error to ensure that the techniques used on the images are appropriate. Herein we introduce HistoClean; a user-friendly, graphical user interface that brings together multiple image processing modules into one easy to use toolkit. HistoClean is an application that aims to help bridge the knowledge gap between pathologists, biomedical scientists and computer scientists by providing transparent image augmentation and pre-processing techniques which can be applied without prior coding knowledge. In this study, we utilise HistoClean to pre-process images for a simple convolutional neural network used to detect stromal maturity, improving the accuracy of the model at a tile, region of interest, and patient level. This study demonstrates how HistoClean can be used to improve a standard deep learning workflow via classical image augmentation and pre-processing techniques, even with a relatively simple convolutional neural network architecture.

To determine the ideal time to apply an implant after augmentation with Bio-Oss Collagen and to observe if there are differences in the age of the patients and the sex, the aim of this randomized controlled clinical trial was to compare the post-extraction changes in angiogenic and osteogenic aspects during spontaneous bone regeneration with those during socket preservation using Bio-Oss Collagen. Sixty-six patients were included in this study. After 8-12 weeks, bone biopsies were embedded in paraffin and histological and immune-histological investigated. Using qRT-PCR bone (Alpl, Bglap, Runx2) and angiogenic markers (VEGF, caveolin-1) were identified. The histomorphometric analysis of all examined samples showed no differences between treated and untreated sockets, but a tissue compression. After classification in bone regeneration stages, more samples with woven bone were present in treated sockets than in controls. The Alpl expression correlates with increase in mature bone tissue. In treated sockets a significant decrease in CD34 and caveolin-1 protein expression was found. Additionally, a significant increase of Runx2 and VEGF mRNA was detected in patients younger than 50 years. Thus, all specimens showed ossification in different stages after eight weeks of healing. The treated group gives an earlier stage of ossification than controls, but produces densified tissue with greater volume fraction. It can be assumed that successful implant placement in Bio-Oss Collagen augmented extraction sockets is possible after eight weeks of bone healing. (C) 2021 Elsevier B.V.

+1482,InProceedings,Implementation of Reliability Methods in a New Developed Open-Source Software Library,"Structural reliability methods aim at the computation of failure probabilities of structural systems with methods of statistical analysis due to varied uncertainties occurring during their design, building or even operating conditions. However, in the field of civil engineering, the use of structural reliability methods unfortunately remains limited to specific cases. Most of the software available has still a limited range concerning wide parametric studies for analysis with reliability methods in civil engineering. This paper describes a new open-source software library as an effective tool for reliability analysis in civil engineering. The goal is to facilitate the adoption of reliability methods among engineers in practice as well as to provide an open platform for further scientific collaboration. The new library is being developed as a so-called ``R package{''} in open-source programming software ``R{''}. The package is capable of carrying out systematic parameter studies using different probabilistic reliability methods, as FORM, SORM, Monte Carlo Simulation. Based on this, an overview on the probabilistic reliability methods implemented in the package as well as results of parametric studies is given. The performance of the package will be shown with a parametric study on a practical example. Most important results of the parametric study as well as the correctness of different reliability methods will be described in the paper. By describing probabilistic methods using an example in practice, engineers can get a basic understanding behind the ideas of probability theories. Further work will result in large parameter studies, which will support the development of a new guideline for reliability in civil engineering. This guideline describes techniques of code calibration as well as to determine new partial safety factors (e.g. for non-metallic reinforced concrete, fixing anchors, etc.). Furthermore, advanced reliability methods (e.g. Monte Carlo with Subset Sampling) will be implemented in the new R package.",10.1007/978-3-030-73616-3\\_30

A compound library of 288 Schiff bases was designed based on compound 10, and a pharmacophore search was performed. Structural analysis of the top scoring hits and a docking study were used to select the best derivatives for the synthesis. Chemical synthesis and structural elucidation of compounds 16a-h were discussed. The antiproliferative activity of 16a-h was evaluated against three cancer (MCF7, A2780 and HT29, IC50 = 0.01-40.50 mu M) and one normal MRC5 (IC50 = 1.27-24.06 mu M) cell lines using the MTT assay. The results revealed the highest antiproliferative activity against MCF7 cells for 16g (IC50 = 0.01 mu M) with an exceptionally high selectivity index of (SI = 578). Cell cycle analysis of MCF7 cells treated with compound 16g revealed a cell cycle arrest at the G(2)/M phase. In addition, compound 16g induced a dose-dependent increase in apoptotic events in MCF7 cells compared to the control. In silico target prediction of compound 16g showed six potential targets that could mediate these activities. Molecular docking analysis of compound 16g revealed high binding affinities toward COX-2, MAP P38 alpha, EGFR, and CDK2. The results of the MD simulation revealed low RMSD values and high negative binding free energies for the two complexes formed between compound 16g with EGFR, and CDK2, while COX-2 was in the third order.

+1484,InProceedings,Influence of Roles in Decision-Making during OSS Development - A Study of Python,"Governance has been highlighted as a key factor in the success of an Open Source Software (OSS) project. It is generally seen that in a mixed meritocracy and autocracy governance model, the decision-making (DM) responsibility regarding what features are included in the OSS is shared among members from select roles; prominently the project leader. However, less examination has been made whether members from these roles are also prominent in DM discussions and how decisions are made, to show they play an integral role in the success of the project. We believe that to establish their influence, it is necessary to examine not only discussions of proposals in which the project leader makes the decisions, but also those where others make the decisions. Therefore, in this study, we examine the prominence of members performing different roles in: (i) making decisions, (ii) performing certain social roles in DM discussions (e.g., discussion starters), (iii) contributing to the OSS development social network through DM discussions, and (iv) how decisions are made under both scenarios. We examine these aspects in the evolution of the well-known Python project. We carried out a data-driven longitudinal study of their email communication spanning 20 years, comprising about 1.5 million emails. These emails contain decisions for 466 Python Enhancement Proposals (PEPs) that document the language's evolution.

Studying the evolution of software and understanding it is a vocal topic of study in software engineering. One of the primary concepts of software evolution is that the internal quality of a software system declines when it evolves. In this paper, the method of evolution of the internal quality of object-oriented open-source software systems has been examined by applying a software metric approach. More specifically, we analyze how software systems evolve over versions regarding size and the relationship between size and different internal quality metrics. The results and observations of this research include: (i) there is a significant difference between different systems concerning the LOC variable (ii) there is a significant correlation between all pairwise comparisons of internal quality metrics, and (iii) the effect of complexity and inheritance on the LOC was positive and significant, while the effect of Coupling and Cohesion was not significant.",10.3390/app11125690
+1490,Article,Investigation and prediction of open source software evolution using automated parameter mining for agent-based simulation,"To guide software development, the estimation of the impact of decision making on the development process can be helpful in planning. For this estimation, often prediction models are used which can be learned from project data. In this paper, an approach for the usage of agent-based simulation for the prediction of software evolution trends is presented. The specialty of the proposed approach lies in the automated parameter estimation for the instantiation of project-specific simulation models. We want to assess how well a baseline model using average (commit) behavior of the agents (i.e., the developers) performs compared to models where different amount of project-specific data is fed into the simulation model. The approach involves the interplay between the mining framework and simulation framework. Parameters to be estimated include, e.g., file change probabilities of developers and the team constellation reflecting different developer roles. The structural evolution of software projects is observed using change coupling graphs based on common file changes. For the validation of simulation results, we compare empirical with simulated results. Our results showed that an average simulation model can mimic general project growth trends like the number of commits and files well and thus, can help project managers in, e.g., controlling the onboarding of developers. Besides, the simulated co-change evolution could be improved significantly using project-specific data.",10.1007/s10515-021-00280-3

The authors found the increasing trends in the vulnerabilities as the lines of code (LOC) increases during the software evolution. This signifies the fact that the addition of new features or change requests into the OSS project may cause an increase in vulnerability. Further, the relation between software vulnerabilities and popularity is also examined. This research does not find the existence of any relationship among software vulnerabilities and popularity.

One of them is maintainability, which in turn is made up of measurable attributes. Previous studies have shown that documentation, by contributing to the comprehensibility of software, may have a positive effect on maintainability and, hence, software quality. This paper presents a study in which we analyzed Javadoc comments from 163 different open-source projects. Javadoc is the de facto standard for documenting source code files in Java projects, and although its syntax is less strict than in other (programming) languages, documentation written with Javadoc may contain violations. Our study focuses on the detection of different types of Javadoc violations as well as the source code elements affected by them. Also, by utilizing software repository mining techniques, we examined the history of the subject systems to gain further insights into the evolution of Javadoc violations. According to our results, about half of the source code elements have no Javadoc whatsoever. Among the different components of Javadoc comments (if present), the description of exceptions, by far, has the highest average ratio of violations. With regard to the types of affected elements, constructors and methods show very high average ratios. Also, we found that, on average, violations live more than two years. Nowadays, most integrated development environments (IDEs) for Java are capable of detecting missing Javadoc comments as well as comments with syntactic errors. However, our results indicate that the documentation of source code might be considered less important to developers or that these tools alone may not be sufficient for maintaining consistent documentation.",10.1109/SANER50967.2021.00031
+1493,Article,LBfoam: An open-source software package for the simulation of foaming using the Lattice Boltzmann Method,"This paper presents a 2D/3D Free Surface Lattice Boltzmann Method simulation package called LBfoam for the simulation of foaming processes. The model incorporates the essential physics of foaming phenomena: gas diffusion into nucleated bubbles, bubble dynamics and coalescence, surface tension, the stabilizing disjoining pressure between bubbles, and Newtonian and non-Newtonian rheological models. The software can simulate the growth and interaction of bubbles, and predict final foam structures. The implementation is based on the Palabos library (in C++), which enables large-scale parallel simulations. The software is freely available under the GNU Affero General Public License version 3.

+1494,InProceedings,Leaving My Fingerprints: Motivations and Challenges of Contributing to OSS for Social Good,"When inspiring software developers to contribute to open source software, the act is often referenced as an opportunity to build tools to support the developer community. However, that is not the only charge that propels contributions-growing interest in open source has also been attributed to software developers deciding to use their technical skills to benefit a common societal good. To understand how developers identify these projects, their motivations for contributing, and challenges they face, we conducted 21 semi-structured interviews with OSS for Social Good (OSS4SG) contributors. From our interview analysis, we identified themes of contribution styles that we wanted to understand at scale by deploying a survey to over 5765 OSS and Open Source Software for Social Good contributors. From our quantitative analysis of 517 responses, we find that the majority of contributors demonstrate a distinction between OSS4SG and OSS. Likewise, contributors described definitions based on what societal issue the project was to mitigate and who the outcomes of the project were going to benefit. In addition, we find that OSS4SG contributors focus less on benefiting themselves by padding their resume with new technology skills and are more interested in leaving their mark on society at statistically significant levels. We also find that OSS4SG contributors evaluate the owners of the project significantly more than OSS contributors. These findings inform implications to help contributors identify high societal impact projects, help project maintainers reduce barriers to entry, and help organizations understand why contributors are drawn to these projects to sustain active participation.",10.1109/ICSE43902.2021.00096

+1499,Article,MASTODON: An Open-Source Software for Seismic Analysis and Risk Assessment of Critical Infrastructure,"Seismic analysis and risk assessment of safety-critical infrastructure like hospitals, nuclear power plants, dams, and facilities handling radioactive materials involve computationally intensive numerical models and coupled multiphysics scenarios. They are also performed in a strict regulatory environment that requires high software quality assurance standards, and in the case of safety-related nuclear facilities, a conformance to the American Society of Mechanical Engineers Nuclear Quality Assurance (NQA-1) standard. This paper introduces the open-source finite-element software, MASTODON (Multi-hazard Analysis of Stochastic Time-Domain Phenomena), which implements state-of-the-art seismic analysis and risk assessment tools in a quality-controlled environment. MASTODON is built on MOOSE (Multi-physics Object-Oriented Simulation Environment), which is a highly parallelizable, NQA-1 conforming, coupled multiphysics, finite-element framework developed at Idaho National Laboratory. MASTODON is capable of fault rupture and source-to-site wave propagation using the domain reduction method, nonlinear site response, and soil-structure interaction analysis, implicit and explicit time integration, automated stochastic simulations, and seismic probabilistic risk assessment. When coupled with other MOOSE applications, MASTODON can also solve strongly and weakly coupled multiphysics problems.

+1500,Article,MCR: Open-Source Software to Automate Compilation of Health Study Report-Back,"Sharing individualized results with health study participants, a practice we and others refer to as ``report-back,{''} ensures participant access to exposure and health information and may promote health equity. However, the practice of report-back and the content shared is often limited by the time-intensive process of personalizing reports. Software tools that automate creation of individualized reports have been built for specific studies, but are largely not open-source or broadly modifiable. We created an open-source and generalizable tool, called the Macro for the Compilation of Report-backs (MCR), to automate compilation of health study reports. We piloted MCR in two environmental exposure studies in Massachusetts, USA, and interviewed research team members (n = 7) about the impact of MCR on the report-back process. Researchers using MCR created more detailed reports than during manual report-back, including more individualized numerical, text, and graphical results. Using MCR, researchers saved time producing draft and final reports. Researchers also reported feeling more creative in the design process and more confident in report-back quality control. While MCR does not expedite the entire report-back process, we hope that this open-source tool reduces the barriers to personalizing health study reports, promotes more equitable access to individualized data, and advances self-determination among participants.",10.3390/ijerph18116104

+1503,Article,Measuring and Modeling Group Dynamics in Open-Source Software Development: A Tensor Decomposition Approach,"Many open-source software projects depend on a few core developers, who take over both the bulk of coordination and programming tasks. They are supported by peripheral developers, who contribute either via discussions or programming tasks, often for a limited time. It is unclear what role these peripheral developers play in the programming and communication efforts, as well as the temporary task-related sub-groups in the projects. We mine code-repository data and mailing-list discussions to model the relationships and contributions of developers in a social network and devise a method to analyze the temporal collaboration structures in communication and programming, learning about the strength and stability of social sub-groups in open-source software projects. Our method uses multi-modal social networks on a series of time windows. Previous work has reduced the network structure representing developer collaboration to networks with only one type of interaction, which impedes the simultaneous analysis of more than one type of interaction. We use both communication and version-control data of open-source software projects and model different types of interaction over time. To demonstrate the practicability of our measurement and analysis method, we investigate 10 substantial and popular open-source software projects and show that, if sub-groups evolve, modeling these sub-groups helps predict the future evolution of interaction levels of programmers and groups of developers. Our method allows maintainers and other stakeholders of open-source software projects to assess instabilities and organizational changes in developer interaction and can be applied to different use cases in organizational analysis, such as understanding the dynamics of a specific incident or discussion.",10.1145/3473139

A trend in the teaching and learning of Artificial Intelligence is to use software where students modify the source code. However, teachers do not use the freedoms of free software in their classrooms. Based on a previous review, it is difficult to see methodological indications to use or create new programs with these characteristics for other teaching-learning processes. The goal of this work is to develop a model of integration of educational free software to the teaching-learning process of Artificial Intelligence. The authors use several research methods: historical-logical, analysis and synthesis, functional-structural-systemic and modeling. The model has three fundamental components. The conceptual component represents the principles and their theoretical foundations. The structural component represents the main elements that intervene in the integration. The instrumental component constitutes the materialization of the model and contains three stages: preparation, execution and evaluation. The authors used the focus group technique, a pre-experiment and Iadov's satisfaction technique to validate the model. These methods made it possible to verify the relevance of the model, its good acceptance by the teachers and the acceptable satisfaction of the students after the first application of the model.",10.1007/978-3-030-52575-0\\_65

The crystallization behavior of high-density polyethylene (HDPE) is implemented according to theoretical and experimental literature. A number of physical interdependencies are included. The cavity is modeled as deformable. The heat transfer coefficient in the thermal contact towards the mold depends on contact pressure. The thermal conductivity is pressure- and crystallinity-dependent. Specific heat depends on temperature and crystallinity. Latent heat is released according to the crystallization progress and temperature. Deviatoric elastic stress is evolved in the solidified material. The prediction of the cavity pressure evolution is used for the assessment of the solution quality because it is experimentally available and governs the residual stress development. Insight into the thermomechanical conditions is provided with through-thickness plots of pressure, temperature and cooling rate at different levels of crystallinity.

The developers' sentiment in this process can have an impact on their working willingness and efficiency. Monitoring sentiment factors can help to improve OSS development and management. However, no method has been proposed to dynamically monitor the sentiment phenomena during the OSS development process. In this paper, an approach to detect Negative Sentiment-related Events (NSE) is proposed. It consists of two steps. The first step is to identify the burst interval of negative comments from open source projects, which corresponds to a NSE. The second step is to annotate this NSE with its event type. To support this approach, the types of NSEs in OSS projects are defined through an empirical study and classifiers are trained to annotate event types automatically. Moreover, conversation disentanglement techniques are employed to make the comments extracted more complete. Finally, the factors that have an influence on NSEs in the OSS project are studied.",10.1109/APSEC53868.2021.00017

Our approach utilizes newly derived analytic gradients for maximizing the transition probability (based on a norm-conserving Crank-Nicolson propagation scheme) for driving a system from a known initial quantum state to another desired state. The NIC-CAGE code is written in the MATLAB and Python programming environments to aid in its readability and general accessibility to both users and practitioners. Throughout this work, we provide several examples and outputs on a variety of different potentials, propagation times, and user-defined parameters to demonstrate the robustness of the NIC-CAGE software package. As such, the use of this predictive tool by both experimentalists and theorists could lead to further advances in both understanding and controlling the dynamics of photo-excited systems.

+1508,Article,Network structure and requirements crowdsourcing for OSS projects,"Crowdsourcing system requirements enables project managers to elicit feedback from a broader range of stakeholders. The advantages of crowdsourcing include a higher volume of requirements reflecting a more comprehensive array of use cases and a more engaged and committed user base. Researchers cite the inability of project teams to effectively manage an increasing volume of system requirements as a possible drawback. This paper analyzes a data set consisting of project management artifacts from 562 open-source software (OSS) projects to determine how OSS project performance varies as the share of crowdsourced requirements increases using six measures of effectiveness: requirement close-out time, requirement response time, average comment activity, the average number of requirements per crowd member, the average retention time for crowd members, and the total volume of requirements. Additionally, the models measure how the impact of increasing the share of crowdsourced requirements changes with stakeholder network structure. The analysis shows that stakeholder network structure impacts OSS performance outcomes and that the effect changes with the share of crowdsourced requirements. OSS projects with more concentrated stakeholder networks perform the best. The results indicate that requirements crowdsourcing faces diminishing marginal returns. OSS projects that crowdsource more than 70\\% of their requirements benefit more from implementing processes to organize and prioritize existing requirements than from incentivizing the crowd to generate additional requirements. Analysis in the paper also suggests that OSS projects could benefit from employing CrowdRE techniques and assigning dedicated community managers to more effectively channel input from the crowd.",10.1007/s00766-021-00353-5
+1509,Article,New Developer Metrics for Open Source Software Development Challenges: An Empirical Study of Project Recommendation Systems,"Software collaboration platforms where millions of developers from diverse locations can contribute to the common open source projects have recently become popular. On these platforms, various information is obtained from developer activities that can then be used as developer metrics to solve a variety of challenges. In this study, we proposed new developer metrics extracted from the issue, commit, and pull request activities of developers on GitHub. We created developer metrics from the individual activities and combined certain activities according to some common traits. To evaluate these metrics, we created an item-based project recommendation system. In order to validate this system, we calculated the similarity score using two methods and assessed top-n hit scores using two different approaches. The results for all scores with these methods indicated that the most successful metrics were binary\\_issue\\_related, issue\\_commented, binary\\_pr\\_related, and issue\\_opened. To verify our results, we compared our metrics with another metric generated from a very similar study and found that most of our metrics gave better scores that metric. In conclusion, the issue feature is more crucial for GitHub compared with other features. Moreover, commenting activity in projects can be equally as valuable as code contributions. The most of binary metrics that were generated, regardless of the number of activities, also showed remarkable results. In this context, we presented improvable and noteworthy developer metrics that can be used for a wide range of open-source software development challenges, such as user characterization, project recommendation, and code review assignment.",10.3390/app11030920

The sensor, based on instantaneous measurements, functions as a position server for dual-axis solar trackers in photovoltaic plants. The proposed device has been developed with free software and hardware, which makes it a pioneering solution because it is open and accessible as well as capable of being improved by the scientific community, thereby contributing to the rapid advancement of technology. In addition, the device includes an algorithm developed ex professo that makes it possible to predetermine the regions of the celestial sphere for which, according to the geometric characteristics of the PV plant, there would be shading between the panels. In this way, solar trackers do not have to locate the Sun's position at all times according to astronomical models, while taking into account factors such as shadows or cloudiness that also affect levels of incident irradiance on solar collectors. Therefore, with this device, it is possible to provide photovoltaic plants with dual-axis solar tracking with a low-cost device that helps to optimise the trajectory of the trackers and, consequently, their radiative capture and energy production.",10.3390/s21030726

However, the mathematical solution of the 3D forward intersection with the analytical definition of spatial lines, resolved by the Minimum Distances Method, is still not widespread in the academic and professional environment. This mathematical modeling determines the 3D coordinates of a point located in the middle of the minimum distance between two or more spatial lines, which spatially ``intersect{''} towards the observation point. This solution is more accurate than others presented in the literature because it simultaneously solves the problem of 3D determination of a point by the method of least squares, in addition to providing an estimate of the coordinate precision, which are inherent to the adjustment. This work, therefore, has the objective of explaining the Minimum Distances Method for the spatial intersection of targeted measurements with a Total Station from two or more known observation points for the 3D determination of inaccessible points located in corners of buildings. For the analysis of the method, a Python tool was developed for QGIS that calculates the 3D coordinates and generates the adjustment processing report, being applied with real observations of the Geodetic survey of the SUDENE building, in Recife-PE. The methodology developed in this work proved to be suitable for measurements of large structures, achieving spherical precision better than +/- 1.0 cm, following the Brazilian standards for urban cadastre.",10.1590/1982-2170-2020-0057

Previous research has addressed the motivations of both individuals and companies to engage with OSS projects. However, limited research has been undertaken that examines and explains the practical mechanisms or work practices used by companies and their developers to pursue their commercial and technical objectives when engaging with OSS projects. This research investigates the variety of work practices used in public communication channels by company contributors to engage with and contribute to eight community OSS projects. Through interviews with contributors to the eight projects we draw on their experiences and insights to explore the motivations to use particular methods of contribution. We find that companies utilise work practices for contributing to community projects which are congruent with the circumstances and their capabilities that support their short- and long-term needs. We also find that companies contribute to community OSS projects in ways that may not always be apparent from public sources, such as employing core project developers, making donations, and joining project steering committees in order to advance strategic interests. The factors influencing contributor work practices can be complex and are often dynamic arising from considerations such as company and project structure, as well as technical concerns and commercial strategies.

+1514,Article,On the prediction of long-lived bugs: An analysis and comparative study using FLOSS projects,"Context: Software evolution and maintenance activities in today's Free/Libre Open Source Software (FLOSS) rely primarily on information extracted from bug reports registered in bug tracking systems. Many studies point out that most bugs that adversely affect the user's experience across versions of FLOSS projects are longlived bugs. However, proposed approaches that support bug fixing procedures do not consider the real-world lifecycle of a bug, in which bugs are often fixed very fast. This may lead to useless efforts to automate the bug management process. Objective: This study aims to confirm whether the number of long-lived bugs is significantly high in popular open-source projects and to characterize the population of long-lived bugs by considering the attributes of bug reports. We also aim to conduct a comparative study evaluating the prediction accuracy of five well-known machine learning algorithms and text mining techniques in the task of predicting long-lived bugs. Methods: We collected bug reports from six popular open-source projects repositories (Eclipse, Freedesktop, Gnome, GCC, Mozilla, and WineHQ) and used the following machine learning algorithms to predict long-lived bugs: K-Nearest Neighbor, Naive Bayes, Neural Networks, Random Forest, and Support Vector Machines. Results: Our results show that long-lived bugs are relatively frequent (varying from 7.2\\% to 40.7\\%) and have unique characteristics, confirming the need to study solutions to support bug fixing management. We found that the Neural Network classifier yielded the best results in comparison to the other algorithms evaluated. Conclusion: Research efforts regarding long-lived bugs are needed and our results demonstrate that it is possible to predict long-lived bugs with a high accuracy (around 70.7\\%) despite the use of simple prediction algorithms and text mining methods.",10.1016/j.infsof.2020.106508

We propose an open source software platform for the planning of image-guided interstitial ablation procedures, providing generic functionality and support for specialized plug-ins. METHODS: The patient's image data is loaded or streamed into the system and the relevant structures are segmented. The user places fiducial points as ablation needle entries and tips, sets the ablation times, and the thermal dose is calculated by a dose engine. The thermal dose is then visualized on the 2D image slices and 3D rendering using a combination of isodose lines and surfaces. Quantitative feedback is provided by dose volume histograms. The treatment plan can be iteratively edited until satisfactory dose distribution is achieved. We performed a usability study with eight novice users in which they were asked to create a satisfactory treatment plan. RESULTS: Interventionists can use the proposed system to create and visualize thermal ablation plans. Researchers can use the platform to create a wide range of specialized applications by adding plug-ins for various types of ablation methods, thermal models, and dose calculation engines. Existing extensions of the platform can provide real-time imaging and tracked or robotic navigation to aid the user in optimal needle placement. From our usability study, the users found the visual information well represented and the platform intuitive to use. The users averaged 4.4 recalculation attempts before finding an optimal treatment, which was evaluated as 100\\% necrosis of the tumor. CONCLUSION: The developed platform fulfills a demand for a universal and shared ablation planning system.

The novel methodology presented here, utilizes a completely free and open source software toolchain for automatically screening unknown alternative foods for toxicity using experimental data from ultra-high-pressure liquid chromatography and mass spectrometry. The process uses three distinct tools (mass spectrometry analysis with MZmine 2, formula assignment with MFAssignR, and data filtering with ToxAssign) enabling it to be modular and easily upgradable in the future. MZmine 2 and MFAssignR have been previously described, while ToxAssign was developed here to match the formulas output by formula assignment to potentially toxic compounds in a local table, then look up toxic data on the Open Food Tox Database for the matched compounds. This process is designed to fill the gap between food safety analysis techniques and developing alternative food production techniques to allow for new methods of food production to be preliminarily tested before animal testing. The methodology was validated against a previous method using proprietary commercial software. The new process identifies all of the toxic elements the previous process identified with more detailed information than the previous process was able to provide automatically.

As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. Objective: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. Methods: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. Results: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. Conclusions: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.",10.2196/20028

+1530,Article,Open-source software migration under sanctions conditions,"Open-source software (OSS) has been widely used in the process of software development for the purpose of shortening the process development and reducing its costs. The growing process of OSS has put out new ways for development, distribution and correspondence of software in organizations. Countries under international sanctions are facing extreme limitations over financial transactions and technology transmissions with different countries; therefore, individuals and companies working in such territories are involved with legal limitations and limits of copyright as to using and having access to software. This research seeks to evaluate the acceptance of OSS in a country under sanction, that's to say Iran. In this research the developed value-based acceptance model has been used. The statistical population of the study was individuals active in software and information technology industry in Iran. The sampling method was convenience sampling. The results indicated that the sanction has a significant effect on the perceived value of OSS (beta = 0.72, p = 0.000) and eventually its usage. Besides, usefulness (beta = 0.69, p = 0.001), perceived enjoyment (beta = 0.54, p = 0.000) and facilitating conditions (beta = 0.58, p = 0.002) are considered as factors effective in applying OSS. As a result, one of the solutions of technology development in sanctioned organizations is to use OSS.",10.1007/s13198-021-01329-y
+1531,InProceedings,Open3DGen: Open-Source Software for Reconstructing Textured 3D Models from RGB-D Images,This paper presents the first entirely open-source and cross-platform software called Open3DGen for reconstructing photorealistic textured 3D models from RGB-D images. The proposed software pipeline consists of nine main stages: 1) RGBD acquisition; 2) 2D feature extraction; 3) camera pose estimation; 4) point cloud generation; 5) coarse mesh reconstruction; 6) optional loop closure; 7) fine mesh reconstruction; 8) UV unwrapping; and 9) texture projection. This end-to-end scheme combines multiple state-of-the-art techniques and provides an easy-to-use software package for real-time 3D model reconstruction and offline texture mapping. The main innovation lies in various Structure-from-Motion (SfM) techniques that are used with additional depth data to yield high-quality 3D models in real-time and at low cost. The functionality of Open3DGen has been validated on AMD Ryzen 3900X CPU and Nvidia GTX1080 GPU. This proof-of-concept setup attains an average processing speed of 15 fps for 720p (1280x720) RGBD input without the offline backend. Our solution is shown to provide competitive 3D mesh quality and execution performance with the state-of-the-art commercial and academic solutions.,10.1145/3458305.3463374
+1533,Article,Optimized single-step (OSS) chemistry for auto-ignition of heterogeneous mixtures,"With the objective of recovering the values of ignition delays of reactive heterogeneous mixtures a singlestep chemistry model has been developed. The corresponding model extends a recent optimization procedure introduced to describe flame propagation in heterogeneous media featuring composition variations (equivalence ratio and temperature) in the fresh reactants or containing residual burned gases (RBG). It is based on the use of an optimized virtual species and a tabulation of the pre-exponential coefficient of an Arrhenius law. The main results of high activation energy asymptotics (AEA) are first recalled to put in evidence the key parameters and the dependence of the ignition delay on the corresponding quantities. The optimization procedure is then applied to these parameters, namely, the pre-exponential factor K and the activation energy E-a of the associated single-step Arrhenius law. An efficient tabulation method benefiting from both rapid access and low storage is proposed for the composition variable (the mixture fraction, in the present case). Finally, the restitution of both ignition and propagation features is ensured through the consideration of the cross-over temperature. The performance of the resulting model is then assessed through comparisons with data obtained from detailed chemistry computations used as reference in several conditions of increasing complexity.

+1535,InProceedings,Organizational Readiness Assessment for Open Source Software Adoption,"Open Source Software (OSS) is probably, the most iconic implementation of Open Innovation business paradigm, due its capacity to concentrate both technical benefits and business advantages. Over time, organizations face the OSS adoption challenge strengthening mainly its internal and technical elements. However, the rapid changes on business dynamics, and the comprehensiveness and fast development of open paradigms, show us that a new set of conditions must be satisfied to reach a successfully OSS adoption. These conditions, considered as a critical success factors, involve a wide range of resources, capacities and skills, both in internal and external scopes. Hence, although adopter organizations should be better prepared to face the challenges related to collaborative innovation, they do not have a systematic approach to value its readiness level to face the adoption challenges. In this context, the present research work proposes a model to assess the organizational readiness, considering the adopter as part of a live business ecosystem, where the relationships originated on co-development with developers' communities, have mutual business impact at strategic, tactic, and operative level.",10.5220/0010497008000807

+1538,Article,Participation in community-based free/libre open source software development tasks: the impact of task characteristics,"Purpose - This paper explores how task characteristics in terms of trigger type and task topic influence individual participation in community-based free/libre open source software (FLOSS) development by considering participation in individual tasks rather than entire projects. Design/methodology/approach - A quantitative study was designed using choose tasks that were carried out via the email discourse on the developers' email fora in five FLOSS projects. Choice process episodes were selected as the unit of analysis and were coded for the task trigger and topic. The impact of these factors on participation (i.e. the numbers of participants and messages) was assessed by regression. Findings - The results reveal differences in participation related to different task triggers and task topics. Further, the results suggest the mediating role of the number of participants in the relationships between task characteristics and the number of messages. The authors also speculate that project type serves as a boundary condition restricting the impacts of task characteristics on the number of participants and propose this relationship for future research. Research limitations/implications - Empirical support was provided to the important effects of different task characteristics on individual participation behaviors in FLOSS development tasks. Practical implications - The findings can help FLOSS participants understand participation patterns in different tasks and choose the types of tasks to attend to. Originality/value - This research explores the impact of task characteristics on participation in FLOSS development at the task level, while prior research on participation in FLOSS development has focused mainly on factors at the individual and/or project levels.",10.1108/INTR-03-2020-0112
+1540,Article,Patient's perception of recovery after osteotome-mediated sinus floor elevation with Bio-Oss collagen compared with no grafting material: a randomized single-blinded controlled trial,"Background Osteotome-mediated sinus floor elevation with or without a grafting material is associated with high implant survival, intrasinus bone gain, and low frequency of complications. However, patient's perception of recovery and satisfaction with the surgical intervention are rarely reported. The objective of the present randomized controlled trial was to assess patient's perception of recovery after osteotome-mediated sinus floor elevation with Bio-Oss collagen compared with no grafting material. Forty healthy patients were randomly allocated to Bio-Oss collagen or no grafting material. Oral health-related quality of life was assessed by Oral Health Impact Profile-14 at enrollment. Patient's perception of recovery was assessed by self-administrated questionnaires and visual analog scale evaluating pain, social and working isolation, physical appearance, duration and quality of life alterations, eating and speaking ability, diet variations, and sleep impairment after 1 week and 1 month, respectively. Descriptive statistics was expressed as mean percentage with standard deviation. Correlation between impaired oral health-related quality of life, age, gender, and recovery were assessed by T test. Level of significance was 0.05. Results Osteotome-mediated sinus floor elevation is associated with high patient satisfaction, limited postoperative discomfort, and willingness to undergo similar surgery. Influence on patient's daily life activities seems to be minimal and limited to the first postoperative days. Most patients managed to return to work and their routine daily activities after 0-2 days. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery. However, number of days with pain, eating difficulties, and sleep disturbances were significantly increased with Bio-Oss collagen compared with no grafting material (P<0.05). Conclusion Patient's discomfort seems to be minimal and limited to the first postoperative days following osteotome-mediated sinus floor elevation with or without a grafting material. Impaired preoperative oral health-related quality of life, gender, or younger age seems not to predispose for delayed recovery.",10.1186/s40729-021-00302-5

+1549,Article,PorePy: an open-source software for simulation of multiphysics processes in fractured porous media,"Development of models and dedicated numerical methods for dynamics in fractured rocks is an active research field, with research moving towards increasingly advanced process couplings and complex fracture networks. The inclusion of coupled processes in simulation models is challenged by the high aspect ratio of the fractures, the complex geometry of fracture networks, and the crucial impact of processes that completely change characteristics on the fracture-rock interface. This paper provides a general discussion of design principles for introducing fractures in simulators, and defines a framework for integrated modeling, discretization, and computer implementation. The framework is implemented in the open-source simulation software PorePy, which can serve as a flexible prototyping tool for multiphysics problems in fractured rocks. Based on a representation of the fractures and their intersections as lower-dimensional objects, we discuss data structures for mixed-dimensional grids, formulation of multiphysics problems, and discretizations that utilize existing software. We further present aPythonimplementation of these concepts in the PorePy open-source software tool, which is aimed at coupled simulation of flow and transport in three-dimensional fractured reservoirs as well as deformation of fractures and the reservoir in general. We present validation by benchmarks for flow, poroelasticity, and fracture deformation in porous media. The flexibility of the framework is then illustrated by simulations of non-linearly coupled flow and transport and of injection-driven deformation of fractures. All results can be reproduced by openly available simulation scripts.",10.1007/s10596-020-10002-5
+1550,InProceedings,Power Relations Within an Open Source Software Ecosystem,"Context: Relationships within open-source software ecosystems (OSSECO) emerge from the collaboration within the ecosystem. Power relations are present in this context whenever an entity has the power of making other entities act as it wants them to act. Therefore, these power relations could affect collaboration within an OSSECO. Objective: This research aims at investigating power relations, their benefits and challenges, and providing an understanding of them within OSSECO. The goal is to provide power relations forms description together with the power relations dynamics associated with them. Method: A systematic mapping study was conducted to extract information about power relations (forms, dynamics, benefits, and challenges) from previous studies. At the end, 10 studies reporting power relations within OSSECO were selected. Next, the data extracted from those was analyzed to understand what power relations affect the OSSECO and how this happens. Based on the results, the power relation forms and dynamics within OSSECO are defined. Results: The systematic mapping study show that power relations are present and affect relationships and interactions within an OSSECO. Moreover, 5 power relations forms and 7 power relations dynamics within OSSECO are presented. Implications: Identifying power relations that might be present within an OSSECO would enable those who study or are members of the ecosystem's community to enhance power relations that support collaboration and to avoid those who can lead developers to leave the OSSECO.",10.1007/978-3-030-91983-2\\_14

Open Street Map (OSM) is a repository containing open geospatial data contributed by millions of people around the globe. With OSM data is possible to create maps that don't reproduce interests of a few, and also, by being open source, it allows auditing on how a decision was made. Although OSM is a free participation platform, it has some socio-technical characteristics that make it difficult for volunteers to participate in geospatial data capture and editing processes.

+1552,Article,"Precision Agriculture Workflow, from Data Collection to Data Management Using FOSS Tools: An Application in Northern Italy Vineyard","In the past decades, technology-based agriculture, also known as Precision Agriculture (PA) or smart farming, has grown, developing new technologies and innovative tools to manage data for the whole agricultural processes. In this framework, geographic information, and spatial data and tools such as UAVs (Unmanned Aerial Vehicles) and multispectral optical sensors play a crucial role in the geomatics as support techniques. PA needs software to store and process spatial data and the Free and Open Software System (FOSS) community kept pace with PA's needs: several FOSS software tools have been developed for data gathering, analysis, and restitution. The adoption of FOSS solutions, WebGIS platforms, open databases, and spatial data infrastructure to process and store spatial and nonspatial acquired data helps to share information among different actors with user-friendly solutions. Nevertheless, a comprehensive open-source platform that, besides processing UAV data, allows directly storing, visualising, sharing, and querying the final results and the related information does not exist. Indeed, today, the PA's data elaboration and management with a FOSS approach still require several different software tools. Moreover, although some commercial solutions presented platforms to support management in PA activities, none of these present a complete workflow including data from acquisition phase to processed and stored information. In this scenario, the paper aims to provide UAV and PA users with a FOSS-replicable methodology that can fit farming activities' operational and management needs. Therefore, this work focuses on developing a totally FOSS workflow to visualise, process, analyse, and manage PA data. In detail, a multidisciplinary approach is adopted for creating an operative web-sharing tool able to manage Very High Resolution (VHR) agricultural multispectral-derived information gathered by UAV systems. A vineyard in Northern Italy is used as an example to show the workflow of data generation and the data structure of the web tool. A UAV survey was carried out using a six-band multispectral camera and the data were elaborated through the Structure from Motion (SfM) technique, resulting in 3 cm resolution orthophoto. A supervised classifier identified the phenological stage of under-row weeds and the rows with a 95\\% overall accuracy. Then, a set of GIS-developed algorithms allowed Individual Tree Detection (ITD) and spectral indices for monitoring the plant-based phytosanitary conditions. A spatial data structure was implemented to gather the data at canopy scale. The last step of the workflow concerned publishing data in an interactive 3D webGIS, allowing users to update the spatial database. The webGIS can be operated from web browsers and desktop GIS. The final result is a shared open platform obtained with nonproprietary software that can store data of different sources and scales.",10.3390/ijgi10040236

We identify families of evolutionary behaviors, or taxa, in FOSS projects. A large percentage of the projects demonstrate very few, if any, actions of schema evolution. Two other taxa involve the evolution via focused actions, with either a single focused maintenance action, or a large percentage of evolution activity grouped in no more than a couple interventions. Schema evolution also involves moderate, and active evolution, with very different volumes of updates to the schema. To the best of our knowledge, this is the first study of this kind in the area of schema evolution, both in terms of presenting profiles of how schemata evolve, and, in terms of the dataset magnitude and the generalizability of the findings.",10.1109/ICDE51399.2021.00008
+1554,Article,Project leaders as boundary spanners in open source software development: A resource dependence perspective,"Digital social innovation is important for addressing various social needs, especially from those who are economically disadvantaged. For instance, open source software (OSS) is developed by mass collaboration on digital communities to provide software users free alternatives to commercial products. OSS is particularly valuable to meet the needs of numerous disadvantaged users for whom proprietary software is not affordable. While OSS projects are lack of formal organizational structure, project leaders play a significant role in initiating and managing these projects and eventually, influencing the degree to which the developed software is used and liked by users. Drawing on resource dependence theory, we investigate the impacts of two team-level characteristics of OSS project leaders (ie, size and tenure) on how well the developed software can address users' needs, with regard to the quantity of software being used by users and the quality of software to users' satisfaction. Further, from a resource dependence perspective, we examine the moderating role of project leaders' network ties in shaping the contingency of these effects. By using a large-scale dataset from 43 048 OSS development projects in SourceForge community, we find empirical evidence corroborating our theory. Taken together, our findings suggest the boundary-spanning role of project leaders in developing digital social innovation.",10.1111/isj.12313
+1556,Article,"Public Works Heritage 3D Model Digitisation, Optimisation and Dissemination with Free and Open-Source Software and Platforms and Low-Cost Tools","This paper describes an innovative, accessible, and sustainable method for enhancing cultural heritage. Documenting and disseminating the public works heritage have now come of age, digitally speaking, with the adoption of new technologies both to further research on and heighten the esteem attributed to the public works heritage. Nonetheless, academic discourse rarely describes procedures for the 3D digitisation of heritage works comprehensible to non-expert readers with limited resources. Taking that premise as a starting point, with special attention to the determinants of the public works heritage, this article aims to define the general, open-source methodology covering 3D model data capture, information processing and optimisation. The article also discusses model dissemination strategies using free platforms and low-cost tools. The general discussion is illustrated with the case study of Ariza Bridge in Spain. This Renaissance-style structure dates from the second half of the sixteenth century. Despite its listing as a cultural heritage asset, the monument was flooded by the Giribaile reservoir waters in 1998 and is now only wholly visible during droughts. The application, developed with open-source software and implemented with free platforms and low-cost tools, features geo-referencing and is designed to be accessible to non-expert users. The methodology proposed is intended as a suitable instrument for the sustainable study, valorisation and dissemination of the built heritage.",10.3390/su132313020
+1559,Article,Quantitative Analysis of Aspergillus nidulans Growth Rate using Live Microscopy and Open-Source Software,"It is well established that colony growth of filamentous fungi, mostly dependent on changes in hyphae/mycelia apical growth rate, is macroscopically estimated on solidified media by comparing colony size. However, to quantitatively measure the growth rate of genetically different fungal strains or strains under different environmental/growth conditions (pH, temperature, carbon and nitrogen sources, antibiotics, etc.) is challenging. Thus, the pursuit of complementary approaches to quantify growth kinetics becomes mandatory in order to better understand fungal cell growth. Furthermore, it is well-known that filamentous fungi, including Aspergillus spp., have distinct modes of growth and differentiation under sub-aerial conditions on solid media or submerged cultures. Here, we detail a quantitative microscopic method for analyzing growth kinetics of the model fungus Aspergillus nidulans, using live imaging in both submerged cultures and solid media. We capture images, analyze, and quantify growth rates of different fungal strains in a reproducible and reliable manner using an open source, free software for bio-images (e.g., Fiji), in a way that does not require any prior image analysis expertise from the user.",10.3791/62778
+1560,Article,Quantitative structure?property relationships for the calculation of the soil adsorption coefficient using machine learning algorithms with calculated chemical properties from open-source software,"The soil adsorption coefficient (Koc) is an environmental fate parameter that is essential for environmental risk assessment. However, obtaining Koc requires a significant amount of time and enormous expenditure. Thus, it is necessary to efficiently estimate Koc in the early stages of a chemical?s development. In this study, a quantitative structure-property relationship (QSPR) model was developed using calculated physicochemical properties and molecular descriptors with the OPEn structure-activity/property Relationship App (OPERA) and Mordred software using the largest available Koc dataset. Specifically, we compared the accuracies of the model using the light gradient boosted machine (LightGBM), a gradient boosting decision tree (GBDT) algorithm, with those of previous models. The experimental results suggested the potential to develop a QSPR model that will produce highly accurate Koc values using molecular descriptors and physicochemical properties. Unlike previous studies, the use of a combination of LightGBM, OPERA and Mordred enables the prediction of Koc for many chemicals with high accuracy. In this study, OPERA was used to calculate the physicochemical properties, and Mordred was used to calculate molecular descriptors. The wide range of chemicals covered by OPERA and Mordred enables the analysis of a diverse range of chemical compounds. We also report a method to tune the LightBGM program. The use of fast-processing software, such as LightGBM, enables parameter tuning of a method required to obtain best performance. Our research represents one of the few studies in the field of environmental chemistry to use LightGBM. Using physicochemical properties as well as molecular descriptors, we could develop highly accurate Koc prediction models when compared to prior studies. In addition, our QSPR models may be useful for preliminary environmental risk assessment without incurring significant costs during the early chemical developmental stage.",10.1016/j.envres.2020.110363

Automated provisioning of network slicing is even more challenging for development. The purpose of this research is to implement a complete, open source, and automatically deployable 5G network slicing architecture. We use OpenStack as the platform required to realize virtualization, Tacker module for slicing environment deployment, free5GC as the core network of the 5G system, and UERANSIM as the role of simulating UE and gNB. Through the proposed architecture, an automatic slicing service with specific functions can be created, the slice can be registered into the 5G network with the support of the core network, and the simulated UE can be used to connect the related slice. Experimental results show that the proposed open-source-based architecture is feasible and the QoS is guaranteed for each slice.",NA
+1562,InProceedings,Representation of Developer Expertise in Open Source Software,"Background: Accurate representation of developer expertise has always been an important research problem. While a number of studies proposed novel methods of representing expertise within individual projects, these methods are difficult to apply at an ecosystem level. However, with the focus of software development shifting from monolithic to modular, a method of representing developers' expertise in the context of the entire OSS development becomes necessary when, for example, a project tries to find new maintainers and look for developers with relevant skills. Aim: We aim to address this knowledge gap by proposing and constructing the Skill Space where each API, developer, and project is represented and postulate how the topology of this space should reflect what developers know (and projects need). Method: we use the World of Code infrastructure to extract the complete set of APIs in the files changed by open source developers and, based on that data, employ Doc2Vec embeddings for vector representations of APIs, developers, and projects. We then evaluate if these embeddings reflect the postulated topology of the Skill Space by predicting what new APIs/projects developers use/join, and whether or not their pull requests get accepted. We also check how the developers' representations in the Skill Space align with their self-reported API expertise. Result: Our results suggest that the proposed embeddings in the Skill Space appear to satisfy the postulated topology and we hope that such representations may aid in the construction of signals that increase trust (and efficiency) of open source ecosystems at large and may aid investigations of other phenomena related to developer proficiency and learning.",10.1109/ICSE43902.2021.00094
+1564,Article,Reproducible Analysis Pipeline for Data Streams: Open-Source Software to Process Data Collected With Mobile Devices,"Smartphone and wearable devices are widely used in behavioral and clinical research to collect longitudinal data that, along with ground truth data, are used to create models of human behavior. Mobile sensing researchers often program data processing and analysis code from scratch even though many research teams collect data from similar mobile sensors, platforms, and devices. This leads to significant inefficiency in not being able to replicate and build on others' work, inconsistency in quality of code and results, and lack of transparency when code is not shared alongside publications. We provide an overview of Reproducible Analysis Pipeline for Data Streams (RAPIDS), a reproducible pipeline to standardize the preprocessing, feature extraction, analysis, visualization, and reporting of data streams coming from mobile sensors. RAPIDS is formed by a group of R and Python scripts that are executed on top of reproducible virtual environments, orchestrated by a workflow management system, and organized following a consistent file structure for data science projects. We share open source, documented, extensible and tested code to preprocess, extract, and visualize behavioral features from data collected with any Android or iOS smartphone sensing app as well as Fitbit and Empatica wearable devices. RAPIDS allows researchers to process mobile sensor data in a rigorous and reproducible way. This saves time and effort during the data analysis phase of a project and facilitates sharing analysis workflows alongside publications.",10.3389/fdgth.2021.769823

Due to the covid-pandemic, people's tasks without physical contact came to the fore, and remote work became more valuable. At the same time, the number of cyber-attacks has suddenly increased, not even sparing hospitals. The aim of this article is to present how to prepare recent security professionals and future experts for work based on SOC implementation and operation from on threat modeling through applying higher quality Information Security solutions. We use open source software environment as prototype. The goal with SOC based on open source software is to demonstrate the perception of a possible cyberattack, in addition, we present the possibility of using it even in enterprise environment. Basically, by applying this direction for training and education purposes, we achieve experts with comprehensive knowledge on newer type of attacks and defense capabilities while they able to apply quick and even risk-proportionate solutions to challenges. A sufficiently in-depth knowledge of an Open source-based SOC solution for educational purposes helps them prepare for the optimal handling of cyber security threats and facilitate the acquisition of in-depth information in the field of Information Security.",10.1109/INES52918.2021.9512928
+1566,Article,RhizoVision Explorer: open-source software for root image analysis and measurement standardization,"Roots are central to the function of natural and agricultural ecosystems by driving plant acquisition of soil resources and influencing the carbon cycle. Root characteristics like length, diameter and volume are critical to measure to understand plant and soil functions. RhizoVision Explorer is an open-source software designed to enable researchers interested in roots by providing an easy-to-use interface, fast image processing and reliable measurements. The default broken roots mode is intended for roots sampled from pots and soil cores, washed and typically scanned on a flatbed scanner, and provides measurements like length, diameter and volume. The optional whole root mode for complete root systems or root crowns provides additional measurements such as angles, root depth and convex hull. Both modes support providing measurements grouped by defined diameter ranges, the inclusion of multiple regions of interest and batch analysis. RhizoVision Explorer was successfully validated against ground truth data using a new copper wire image set. In comparison, the current reference software, the commercial WinRhizo (TM), drastically underestimated volume when wires of different diameters were in the same image. Additionally, measurements were compared with WinRhizo (TM) and IJ\\_Rhizo using a simulated root image set, showing general agreement in software measurements, except for root volume. Finally, scanned root image sets acquired in different labs for the crop, herbaceous and tree species were used to compare results from RhizoVision Explorer with WinRhizo (TM). The two software showed general agreement, except that WinRhizo (TM) substantially underestimated root volume relative to RhizoVision Explorer. In the current context of rapidly growing interest in root science, RhizoVision Explorer intends to become a reference software, improve the overall accuracy and replicability of root trait measurements and provide a foundation for collaborative improvement and reliable access to all.",10.1093/aobpla/plab056
+1568,Article,SIRT6-specific inhibitor OSS-128167 exacerbates diabetic cardiomyopathy by aggravating inflammation and oxidative stress,"Diabetic cardiomyopathy (DCM) is a serious complication of diabetes, which importantly contributes to the increased mortality of patients with diabetes. The development of DCM is accompanied by numerous pathological mechanisms, including oxidative stress and chronic inflammation. Accordingly, the present study aimed to determine the effects of the sirtuin 6 (SIRT6) inhibitor OSS-128167 on DCM using a mouse model of streptozotocin (STZ)-induced diabetes and high glucose (HG)-treated cardiomyocytes. C57BL/6 mice were intraperitoneally injected with STZ for 5 days to simulate the diabetic cardiomyopathy model. Mice with STZ-induced diabetes (STZ-DM1) were orally administered OSS-128167 (20 or 50 mg/kg) through gavage every other day. The expression of SIRT6 in myocardial tissue was detected using western blotting. Tissue staining (hematoxylin and eosin and Masson's trichrome) was used to characterize myocardial structure, TUNEL fluorescent staining was used to detect myocardial apoptosis, and immunohistochemical staining was used to detect the expression of inflammatory factors in myocardial tissue. Dihydroethidium staining and a malondialdehyde (MDA) detection kit were used to detect the oxidative stress levels in myocardial tissues. In vitro, H9c2 cells were pre-incubated with OSS-128167 for 1 h and then stimulated with HG (33 mM) for various durations. Expression levels of fibrosis markers, collagen-1 and transforming growth factor (TGF)-beta, apoptosis-related proteins, Bax, Bcl-2 and cleaved-poly ADP-ribose polymerase, tumor necrosis factor-alpha and the oxidative stress metabolite, 3-nitrotyrosine were analyzed using western blotting and reverse transcription-quantitative PCR. Commercially available kits were used to detect the activity of caspase-3 and the content of MDA in the H9c2 cell line. The corresponding results demonstrated that OSS-128167 aggravated diabetes-induced cardiomyocyte apoptosis and fibrosis in mice. Mechanistically, OSS-128167 was revealed to increase the levels of inflammatory factors and reactive oxygen species (ROS) in vitro and in vivo. In conclusion, OSS-128167 facilitated the inflammatory response and promoted the production of ROS while aggravating DCM development. These findings indicated that SIRT6 may target two closely combined and interacting pathological processes, the inflammatory response and oxidative stress, and may serve as a potentially advantageous therapeutic target.",10.3892/mmr.2021.12006

However, the research on the relationship between network structure and developers’ contribution is still insufficient. This paper investigates developer collaboration networks in three OSS communities by data analytics. The results indicate that real networks are mainly characterized by the modular small-world structure, which is inherently correlated with the sub-project participation of developers. Most module members are single-dimensional developers whose coding-collaboration focuses on a small number of sub-projects (called the main dimension of the module), while a small proportion of module members are multi-dimensional developers who conduct coding-collaboration in the main dimension of different modules. These results may deepen our understandings of the collaborative pattern of OSS communities, and also have some reference value for the studies of open collaborative innovation in large-scale crowds.",10.1145/3478905.3478923

The goal of this tutorial is to disseminate skills in structure-based drug design and to allow others to unleash their own creativity to design new drugs to fight the current pandemic. The tutorial begins with the X-ray crystallographic structure of the main protease (M-pro) of the SARS coronavirus (SARS-CoV) bound to a peptide substrate and then uses the UCSF Chimera software to modify the substrate to create a cyclic peptide inhibitor within the M-pro active site. Finally, the tutorial uses the molecular docking software AutoDock Vina to show the interaction of the cyclic peptide inhibitor with both SARS-CoV M-pro and the highly homologous SARS-CoV-2 M-pro. The supporting information provides an illustrated step-by-step protocol, as well as a video showing the inhibitor design process, to help readers design their own drug candidates for COVID-19 and the coronaviruses that will cause future pandemics. An accompanying preprint in bioRxiv {[}https://doi.org/10.1101/2020.08.03.234872] describes the synthesis of the cyclic peptide and the experimental validation as an inhibitor of SARS-CoV-2 M-pro.

+1573,InProceedings,Support for Broadening Participation though Humanitarian Free and Open Source Software,The necessity and benefits of broadening participation in computing and the roles that computing programs must play in addressing this challenge have been well documented. Elevating the social value of computing has been advocated as an approach to increasing the appeal of computing to both women and other underrepresented groups. This poster adds empirical support for that approach. It reports on the analysis of projects selected by students over four years of a two-semester senior capstone. In this capstone students select Free and Open Source Software (FOSS) communities with which to engage. The students learned about FOSS principles and processes and were introduced to humanitarian FOSS (HFOSS). They completed pre-semester surveys and engaged in a three-stage project selection process. The types of projects that students considered (FOSS or HFOSS) support the assertion that computing with social value is appealing to both females and students in underrepresented groups. Analysis of pre-semester attitude surveys adds additional insight and suggests further avenues for investigation.,10.1145/3408877.3439629
+1574,Article,Task-based structures in open source software: revisiting the onion model,"Studies on Open Source Software (OSS) developer communities have long stated that there is a relationship between community structure and tasks carried out by project members. This relationship has been exemplified by the onion model, which has been instrumental in understanding self-coordination in OSS projects. Despite its ubiquity, there is a lack of empirical evidence to validate the relative position of each task cluster within the onion model. In this study, we map out the community structure of a large open source project and observe its bug-fixing patterns to explore the relationship between tasks and structure. Our study makes three significant contributions. First, we find no empirical evidence to support the structural location of bug-fixing tasks in the onion structure. Second, we find empirical evidence to support the core-periphery continuum model linking an actor'scorenessto problem-solving ability. Third, our results suggest that the importance and location of each task within the core-periphery structure evolve over time. These findings add clarity to the community structure and their implications for the management and coordination of collaborative innovation projects.",10.1111/radm.12428

Mainly because there are commercial alternatives that have an army of expert developers behind them, experienced supporters and wellestablished business processes in their development and promotion. Nevertheless, web-based applications, that securely handle the users' personal data are an area of freedom and ease of use, features that make such applications very attractive. The ``ease-of-use{''} part is very hard to achieve, for the developers and the end-users. Dependencies change often in OSS packages, so the fear that something breaks is always around the corner. If the application looks attractive, additional user requirements fall like rain. This poses a problem of continuity, maintenance and operational quality of the packages.

+1577,Article,"The ImageJ ecosystem: Open-source software for image visualization, processing, and analysis","For decades, biologists have relied on software to visualize and interpret imaging data. As techniques for acquiring images increase in complexity, resulting in larger multidimensional datasets, imaging software must adapt. ImageJ is an open-source image analysis software platform that has aided researchers with a variety of image analysis applications, driven mainly by engaged and collaborative user and developer communities. The close collaboration between programmers and users has resulted in adaptations to accommodate new challenges in image analysis that address the needs of ImageJ's diverse user base. ImageJ consists of many components, some relevant primarily for developers and a vast collection of user-centric plugins. It is available in many forms, including the widely used Fiji distribution. We refer to this entire ImageJ codebase and community as the ImageJ ecosystem. Here we review the core features of this ecosystem and highlight how ImageJ has responded to imaging technology advancements with new plugins and tools in recent years. These plugins and tools have been developed to address user needs in several areas such as visualization, segmentation, and tracking of biological entities in large, complex datasets. Moreover, new capabilities for deep learning are being added to ImageJ, reflecting a shift in the bioimage analysis community towards exploiting artificial intelligence. These new tools have been facilitated by profound architectural changes to the ImageJ core brought about by the ImageJ2 project. Therefore, we also discuss the contributions of ImageJ2 to enhancing multidimensional image processing and interoperability in the ImageJ ecosystem.",10.1002/pro.3993

As F/OSS has become larger and more established, we investigate the labor of maintaining and sustaining those projects at various scales. We report findings from an interview-based study with contributors and maintainers working in a wide range of F/OSS projects. Maintainers of F/OSS projects do not just maintain software code in a more traditional software engineering understanding of the term: fixing bugs, patching security vulnerabilities, and updating dependencies. F/OSS maintainers also perform complex and often-invisible interpersonal and organizational work to keep their projects operating as active communities of users and contributors. We particularly focus on how this labor of maintaining and sustaining changes as projects and their software grow and scale across many dimensions. In understanding F/OSS to be as much about maintaining a communal project as it is maintaining software code, we discuss broadly applicable considerations for peer production communities and other socio-technical systems more broadly.",10.1145/3449249
+1580,Article,The Long Road Ahead: Ongoing Challenges in Contributing to Large OSS Organizations and What to Do,"Open source communities hosted in large foundations operate in a complex socio-technical ecosystem, which includes a heterogeneous mix of projects and stakeholders. Previous work has thus far investigated the challenges faced in OSS communities from the point of view of specific stakeholders, primarily at the level of individual projects. None have yet studied the challenges faced within a large, federated open source organization. In this paper, we aim to bridge this gap to identify ongoing challenges contributors face in a mature OSS organization. To do so, we surveyed 624 contributors at the Apache Software Foundation (ASF) and ran 11 semi-structured follow up interviews. We validated our findings through member checking with the interviewees as well as the ASF Diversity and Inclusion (D&I) committee. The contributions of this paper include: (1) an empirically-evidenced conceptual model of the 88 challenges that contributors face in a mature OSS foundation and (2) a set of 48 community-recommended strategies for alleviating these challenges. Our results show that even well-established and mature organizations still face a variety of individual and project-specific challenges and that it is difficult to design a comprehensive set of processes and guidelines to match the needs and expectations of a diverse and large federated community. Our conceptual challenges model and associated strategies to mitigate them can provide guidance to other OSS foundations and projects helping them in building better support processes and tools to create a successful, thriving community of contributors.",10.1145/3479551

Our aim is to explore the intersection between FOSS and computational reproducibility. We begin by situating FOSS in relation to other `open' initiatives, and specifically open science, open research, and open scholarship. In this context, we argue that anyone who actively contributes to the research process today is a computational researcher, in that they use computers to manage and store information. We then provide a primer to FOSS suitable for anyone concerned with research quality and sustainability-including researchers in any field, as well as support staff, administrators, publishers, funders, and so on. Next, we illustrate how the notions introduced in the primer apply to resources for scientific computing, with reference to the GNU Scientific Library as a case study. We conclude by discussing why the common interpretation of `open source' as `open code' is misplaced, and we use this example to articulate the role of FOSS in research and scholarship today.

Aligned with work that builds on the notion that an OSS development is tightly interrelated with its social environment (i.e., the OSS community), this study examines the relationship between interproject structure and OSS project success. OSS project success is reflected in two forms: popularity and knowledge creation. Extending the extant OSS literature, we theorize a contingent role of interproject connectedness. In particular, we posit three points: (1) an OSS project with more structural holes achieves higher popularity; (2) an OSS project with fewer structural holes yields higher knowledge creation; and (3) these two relationships are enhanced by an increase in project maturity. Using a dataset longitudinally collected from SourceForge.net, we found that OSS projects with widespread connectedness are more popular. This is especially so for those OSS projects in the mid-mature stage. We also found that OSS projects with a cohesive network achieve higher knowledge creation, irrespective of their maturity. Findings from our study can contribute to OSS literature by identifying OSS projects that are more likely to be successful.",10.1016/j.jsis.2020.101598

We leverage Opportunity-Motivation-Ability (OMA) theory to explain that inbound open innovation provides opportunities to access external knowledge in open innovation community networks; but whether a project can absorb and utilize such external knowledge depends on outbound open innovation and project team role diversity, which influence the team members? motivation and ability to do so. Using a large sample of open source software projects, the empirical findings suggest project performance should be distinguished as internal (technical performance) and external (market performance) to understand the effects of open innovation strategy. Technical performance is enhanced with a coupled open innovation strategy that leverages both high outbound open innovation and high inbound open innovation, in conjunction with low team role diversity. However, an inbound open innovation strategy is optimal for market performance, particularly when team role diversity is high. Thus, project team role diversity explains the trade-off effects of inbound and outbound open innovation strategies on project technical performance and market performance.",10.1016/j.indmarman.2021.02.013

+1588,Article,"They Can Only Ever Guide"": How an Open Source Software Community Uses Roadmaps to Coordinate Effort","Unlike in commercial software development, open source software (OSS) projects do not generally have managers with direct control over how developers spend their time, yet for projects with large, diverse sets of contributors, the need exists to focus and steer development in a particular direction in a coordinated way. This is especially important for ""infrastructure"" projects, such as critical libraries and programming languages that many other people depend on. Some projects have taken the approach of borrowing planning tools that originated in commercial development, despite the fact that these techniques were designed for very different contexts, e.g. strong top-down control and profit motives. Little research has been done to understand how these practices are adapted to a new context. In this paper, we examine the Rust project's use of roadmaps: how has an important OSS infrastructure project adapted an inherently top-down tool to the freewheeling world of OSS? We find that because Rust's roadmaps are built in part by summarizing what motivated developers most prefer to work on, they are in some ways more a description of the motivated labor available than they are a directive that the community move in a particular direction. They allow the community to avoid wasting time on unpopular proposals by revealing that there will be little help in building them, and encouraging work on popular features by making visible the amount of consensus in those features. Roadmaps generate a collective focus without limiting the full scope of what developers work on: roadmap issues consume proportionally more effort than other issues, but constitute a minority of the work done (i.e issues and pull requests made) by both central and peripheral participants. They also create transparency among and beyond the community into what central contributors' plans are, and allow more rational decision-making by providing a way for evidence about community needs to be linked to decision-making.",10.1145/3449232

However, these models lack consensus between scholars as well as standard bodies on a specific set of usability evaluation criteria. Retaining irrelevant criteria and omitting essential ones will mislead the direction of the usability evaluation. Objective: This study introduces a three-step method to develop a usability evaluation model in the context of OSS. Method: The fuzzy Delphi method has been employed to unify the usability evaluation criteria in the context of OSS. The first step in the method is the usability criteria analysis, which involves redefining and restructuring all collected usability criteria reported in the literature. The second step is fuzzy Delphi analysis, which includes the design and validates the fuzzy Delphi instrument and the utilisation of the fuzzy Delphi method to analyse the fuzziness consensus of experts' opinions on the usability evaluation criteria. The third step is the proposal of the OSS usability evaluation model. Results: A total of 124 usability criteria were identified, redefined, and restructured by creating groups of related meaning criteria. The result of the groupings generated 11 main criteria; the findings of the fuzzy Delphi narrowed down the criteria to only seven. The final set of criteria was sent back to the panellists for reconsideration of their responses. The panellists verified that these criteria are suitable in the evaluation of the usability of OSS. Discussion: The empirical analysis confirmed that the proposed evaluation model is acceptable in assessing the usability of OSS. Therefore, this model can be used as a reference metric for OSS usability evaluation which will have a practical benefit for the community in public and private organisations in helping the decision-maker to select the best OSS software package amongst the alternatives.",10.1016/j.infsof.2020.106453

In the context of applying open-source software, the differences in the numerical results due to different model parameters need to be investigated in detail. In this study, some benchmark problems have been solved with DualSPHysics to validate the estimation of wave impact pressure with violent breaking waves. We have demonstrated three main results: (i) as an alternative to the artificial viscosity traditionally used in DualSPHysics, a laminar viscosity model can also well reproduce the solutions to the existing benchmark problems in a violent flow field with the modified dynamic boundary condition; (ii) the dynamics of the gas phase is essential in the calculation of wave breaking with rapid gate opening; and (iii) if the density diffusion parameter is too large, the impact pressure may be underestimated. The practical contribution by this study is to find that DualSPHysics well reproduces complex breaking waves, including multi-phase gas-liquid flows, and that the wave impact pressure is accurate by comparison with existing experimental results. This allows us to understand the complex behavior of fluid-structure interactions in coastal engineering by means of DualSPHysics.",10.1080/21664250.2021.1991608

+1598,InProceedings,What Makes Open Source Software Projects Impactful: A Data-Driven Approach,"With the wide adoption and acceptance of open source version control and hosting systems, more and more companies, including Google, Microsoft, Apple and Facebook, are putting their projects on such platforms, e.g., GitHub. It is very important for open source projects to be impactful, i.e., to attract attentions from the open source development community, so as to gain support on development, testing as well as maintenance from the community. However, the question of what factors affect open source project impact, remains largely open. Given the numerous confounding factors and the complex correlations among the factors, it is a challenge to answer the question. In this study, we gather a large dataset from GitHub and provide empirical insights on this question base on a data-driven approach. We randomly collect 146, 286 projects from GitHub and then adopt data analysis techniques to automatically analyze the correlations of different features with the software project impact. We also provide suggestions on how to potentially make open source projects impactful base on our analysis results.",10.1145/3457913.3457932

This article aims to bridge current research on blockchain technology to earlier research on open source software (OSS) and to suggest a number of concepts from OSS research that are useful in discussing governance of blockchain systems. Thus, the purpose of this article is to provide a theoretically oriented review of some of the earlier concepts and discuss their applicability in a novel context. Bridging these extending literatures and concepts accelerates theoretical development in the area of governance of technology, opening fertile avenues for future research and offering a variety of insights to both practitioners.",10.3389/fhumd.2021.642556
+1601,Article,When and How to Make Breaking Changes: Policies and Practices in 18 Open Source Software Ecosystems,"Open source software projects often rely on package management systems that help projects discover, incorporate, and maintain dependencies on other packages, maintained by other people. Such systems save a great deal of effort over ad hoc ways of advertising, packaging, and transmitting useful libraries, but coordination among project teams is still needed when one package makes a breaking change affecting other packages. Ecosystems differ in their approaches to breaking changes, and there is no general theory to explain the relationships between features, behavioral norms, ecosystem outcomes, and motivating values. We address this through two empirical studies. In an interview case study, we contrast Eclipse, NPM, and CRAN, demonstrating that these different norms for coordination of breaking changes shift the costs of using and maintaining the software among stakeholders, appropriate to each ecosystem's mission. In a second study, we combine a survey, repository mining, and document analysis to broaden and systematize these observations across 18 ecosystems. We find that all ecosystems share values such as stability and compatibility, but differ in other values. Ecosystems' practices often support their espoused values, but in surprisingly diverse ways. The data provides counterevidence against easy generalizations about why ecosystem communities do what they do.",10.1145/3447245
+1603,InProceedings,Who are Vulnerability Reporters? A Large-scale Empirical Study on FLOSS,"(Background) Software vulnerabilities pose a serious threat to the security of computer systems. Hence, there is a constant race for defenders to find and patch them before attackers are able to exploit them. Measuring different aspects of this process is important in order to better understand it and improve the odds for defenders. (Aims) The human factor of the vulnerability discovery and patching process has received limited attention. Better knowledge of the characteristics of the people and organizations who discover and report security vulnerabilities can considerably enhance our understanding of the process, provide insights regarding the expended effort in vulnerability hunting, contribute to better security metrics, and help guide practical decisions regarding the strategy of projects to attract vulnerability researchers.(Method) In this paper, we present what is, to the best of our knowledge, the first large-scale empirical study on the people and organizations who report vulnerabilities in popular FLOSS projects. Collecting data from a multitude of publicly available sources (NVD, bug-tracking platforms, vendor advisories, source code repositories), we create a dataset of reporter information for 2193 unique reporting entities of 4756 CVEs affecting the Mozilla suite, Apache httpd, the PHP interpreter, and the Linux kernel. We use the dataset to investigate several aspects of the vulnerability discovery process, specifically regarding the distribution of contributions, their temporal characteristics, and the motivations of reporters.(Results) Among our results: around 80% of reports come from 20% of reporters; first time reporters are significant contributors to the yearly total in all 4 projects; productive reporters are specialized w.r.t. the project and vulnerability types; around half of all reports come from reporters acknowledging an affiliation.(Conclusions) Projects depend both on a core of dedicated and productive reporters, and on small contributions from a large number of community reporters. The generalized Pareto principle (the (1 - p)/p law) can be used as a metric for the concentration of contributions in the vulnerability-reporting ecosystem of a project.",10.1145/3475716.3475783

Both incorporating and revising the work of Charles Lyell, Oliver Goldsmith, and Georges Cuvier, Eliot emphasises the interconnectedness of human and planetary processes, feminises environmental catastrophe, and blends human and ecological history.

+1605,Article,`SleepCycles' package for R - A free software tool for the detection of sleep cycles from sleep staging,"The detection of NREM-REM sleep cycles in human sleep data (i.e., polysomnographically assessed sleep stages) enables fine-grained analyses of ultradian variations in sleep microstructure (e.g., sleep spindles, and arousals), or other amplitude- and frequency-specific electroencephalographic features during sleep. While many laboratories have software that is used internally, reproducibility requires the availability of open-source software. Therefore, we here introduce the `SleepCycles' package for R, an open-source software package that identifies sleep cycles and their respective (non-) rapid eye movement ({[}N]REM) periods from sleep staging data. Additionally, each (N)REM period is subdivided into parts of equal duration (percentiles), which may be useful for further fine-grained analyses. The detection criteria used in the package are, with some adaptations, largely based on criteria originally proposed by Feinberg and Floyd (1979). The latest version of the package can be downloaded from the Comprehensive R Archives Network (CRAN). The package `SleepCycles' for R allows to identify sleep cycles and their respective NREM and REM periods from sleep staging results. Besides the cycle detection, NREM and REM periods are also split into parts of equal duration (percentiles) thereby allowing for a better temporal resolution across the night and comparisons of sleep cycles with different durations amongst different night recordings.

+1606,Article,pMAT: An open-source software suite for the analysis of fiber photometry data,"The combined development of new technologies for neuronal recordings and the development of novel sensors for recording both cellular activity and neurotransmitter binding has ushered in a new era for the field of neuroscience. Among these new technologies is fiber photometry, a technique wherein an implanted fiber optic is used to record signals from genetically encoded fluorescent sensors in bulk tissue. Fiber photometry has been widely adapted due to its cost-effectiveness, ability to examine the activity of neurons with specific anatomical or genetic identities, and the ability to use these highly modular systems to record from one or more sensors or brain sites in both superficial and deep-brain structures. Despite these many benefits, one major hurdle for laboratories adopting this technique is the steep learning curve associated with the analysis of fiber photometry data. This has been further complicated by a lack of standardization in analysis pipelines. In the present communication, we present pMAT, a `photometry modular analysis tool' that allows users to accomplish common analysis routines through the use of a graphical user interface. This tool can be deployed in MATLAB and edited by more advanced users, but is also available as an independently deployable, open-source application.",10.1016/j.pbb.2020.173093

However, current data processing software either lack functionality for environmental sciences, solve only part of the workflow, are not openly available and/or are restricted in input data formats. In this paper we present patRoon, a new R based open-source software platform, which provides comprehensive, fully tailored and straightforward non-target analysis workflows. This platform makes the use, evaluation and mixing of well-tested algorithms seamless by harmonizing various common (primarily open) software tools under a consistent interface. In addition, patRoon offers various functionality and strategies to simplify and perform automated processing of complex (environmental) data effectively. patRoon implements several effective optimization strategies to significantly reduce computational times. The ability of patRoon to perform time-efficient and automated non-target data annotation of environmental samples is demonstrated with a simple and reproducible workflow using open-access data of spiked samples from a drinking water treatment plant study. In addition, the ability to easily use, combine and evaluate different algorithms was demonstrated for three commonly used feature finding algorithms. This article, combined with already published works, demonstrate that patRoon helps make comprehensive (environmental) non-target analysis readily accessible to a wider community of researchers.",10.1186/s13321-020-00477-w

At present, however, it still lacks a powerful, easy-to-use, and user-friendly professional software concerning generation and assessment of digital speckle pattern. Researchers have to reimplement the generation algorithms in literature by themselves, which is time-consuming and error-prone. This paper reports a free and open-source software, Glare, for generation and assessment of digital speckle pattern. Glare has functions including generating speckle patterns, rendering deformed images, assessing pattern quality, and presenting pattern recommendations: Glare can generate ellipse, polygon, and Gaussian speckle patterns; can render deformed images with underlying deformation fields of translation, stretch/compression, rotation, sinusoidal deformation, Gaussian deformation, and Portevin-Le Chatelier band deformation; can calculate key pattern quality assessment parameters such as speckle coverage, speckle size, systematic error, and random error; can produce optimized speckle pattern in form of vector image. The software realizes real-time deformed image rendering with the aid of fast initial value estimation algorithm for backward mapping and pattern pre-rendering technique, and improves the computational efficiency of sum of square of subset intensity gradients by integral image method. In general, the software can be used not only for scientific research and engineering applications in digital image correlation community but also for education of experimental mechanics, and therefore has broad prospects.",10.1016/j.optlaseng.2021.106766

+1610,Article,A Motivation-Hygiene Model of Open Source Software Code Contribution and Growth,"The success of open source software (OSS) projects depends on sustained contributions by developers who often display a wide variety of contribution patterns. Project leaders and stakeholders would strongly prefer that developers not only maintain but preferably increase their contributions over time as they gain experience. Corporations increasingly complement OSS developer motivations (such as fit in terms of shared values with the project community) by paying them to sustain contributions. However, practitioners argue whether payment helps or hurts projects because monetary compensation may dampen developer motivation in the long run, making it difficult for project leaders to understand what to expect from developers over time. Using Herzberg's motivation-hygiene framework, we explore how developers' perceptions of value fit with the project and being paid interact to determine the level of code contribution and its rate of change over time (i.e., growth). Using a survey of 564 developers across 431 projects on GitHub, we build a three-level growth model explaining the code contribution and its growth over a six-month period. We find that value fit with the project positively influences both the level and growth of code contribution. However, there are notable differences among paid and unpaid developers in the impact of value fit on their level and growth in code contributions over time. The implications of our work will be of interest to researchers, practitioners, and organizations investing in open source projects.",10.17705/1jais.00712

This paper presents a new workflow of automated image processing to utilize poor-quality X-ray CT scan images. The workflow runs on the open-source image analysis software and efficiently separates desired features from low-contrast scanned images. The new workflow is a two-step technique using contrast enhancement and automated feature segmentation to generate noise-free binary images. The results of binary images using the proposed workflow and using a conventional thresholding technique are analyzed to show the quality of the proposed method. The paper also presents a workflow of estimating the structural geometries of features in two and three dimensions. The results of the structural feature analyses and computational time were compared between the open-source (ImageJ) and commercial image analysis software (Bruker Computed Tomography Analyzer). The commercial software was more computationally efficient, but the task-specific macros in open-source software enabled the user-desired automation in image processing and data extraction of desired structural features of comparable quality.",10.1007/s42461-022-00662-5

+1614,InProceedings,A Supervised Generative Topic Model to Predict Bug-fixing Time on Open Source Software Projects,"During software maintenance activities an accurate prediction of the bug-fixing time can support software managers to better resources and time allocation. In this work, each bug report is endowed with a response variable (bug-fixing time), external to its words, that we are interested in predicting. To analyze the bug reports collections, we used a supervised Latent Dirichlet Allocation (sLDA), whose goal is to infer latent topics that are predictive of the response. The bug reports and the responses are jointly modeled, to find latent topics that will best predict the response variables for future unlabeled bug reports. With a fitted model in hand, we can infer the topic structure of an unlabeled bug report and then form a prediction of its response. sLDA adds to LDA a response variable connected to each bug report. Two different variants of the bag-of-words (BoW) model are used as baseline discriminative algorithms and also an unsupervised LDA is considered. To evaluate the proposed approach the defect tracking dataset of LiveCode, a well-known and large dataset, was used. Results show that SLDA improves recall of the predicted bug-fixing times compared to other BoW single topic or multi-topic supervised algorithms.",10.5220/0011113100003176

It is known that the software systems tend to increase their complexity and size over their evolution to meet the demands required by the users. Due to this fact, researchers have increasingly carried out studies on software evolution to understand the systems' evolution pattern and propose techniques to overcome inherent problems in software evolution. Many of these works collect data but do not make them publicly available. Many datasets on software evolution are outdated, and/or are small, and some of them do not provide time series from software metrics. We propose an extensive software evolution dataset with temporal information about open-source Java systems.

Here we present a wide range of free and open source software tools that are used in biomedical sequencing workflows around the world today. Since its introduction in 2011 the variant call format (VCF) has been widely adopted for processing DNA and RNA variants in practically all population studies-as well as in somatic and germline mutation studies. The VCF format can represent single nucleotide variants, multi-nucleotide variants, insertions and deletions, and simple structural variants called and anchored against a reference genome.Here we present a spectrum of over 125 useful, complimentary free and open source software tools and libraries, we wrote and made available through the multiple vcflib, bio-vcf, cyvcf2, hts-nim and slivar projects. These tools are applied for comparison, filtering, normalisation, smoothing and annotation of VCF, as well as output of statistics, visualisation, and transformations of files variants. These tools run everyday in critical biomedical pipelines and countless shell scripts. Our tools are part of the wider bioinformatics ecosystem and we highlight best practices.We shortly discuss the design of VCF, lessons learnt, and how we can address more complex variation through pangenome graph formats, variation that can not easily be represented by the VCF format.",10.1371/journal.pcbi.1009123

The rule established from the case of Foss vs. Harbottle, which paved way for exploitation of the minority shareholders, giving excessive power at the hands of the office-bearers, has always been a hindrance to secure a protection to the minority shareholders who do not get an opportunity to approach the Court for seeking justice as they are considered unauthorised to do so. The instances whereby the rights of the minority shareholders have been infringed or violated are enormous in number, and the requirement to secure an amicable environment for these small in shareholdings yet large numbers of shareholders has increased with time. Recently, in the judgment, considering the prevalence of the majority rule, the decision was given in favour of the majority shareholders of the Company, posing a threat to the position of the minority shareholders, yet again in the corporate world. Thus, the researcher here, attempts to critically analyse the majority rule, discussing in brief the case of Foss vs. Harbottle developed contrary to the interests of the minority shareholders, and appraise the exceptions provided under the Majority rule which also acts as a measure to protect the rights of minority shareholders.

A semi-automated method for measuring rat uterus morphology using free and open-source software (Gimp and FIJI) is demonstrated in this paper. Research was performed on ovariectomized rats as a model of osteoporosis (with sham-operated control group). The animals were treated with alendronate, hop extract or the combination of the two. Whole histological slides were photographed and images were manually pre-processed in Gimp. Color masks from Gimp were loaded in FIJI and polar transformation and meas-urements were made using a custom macro. This analysis was supplemented by manual assessment of Ki67 proliferation marker expression by a pathologist. Our results suggest that monotherapy or combination therapy with alendronate and hop extract does not cause proliferation of the endometrium in ovariectomized rats and would be safe for use in osteoporosis treatment in this regard. The semi-automated method used in this research is more precise and unbiased than older manual methods. Furthermore, it can be easily adapted for analysis of whole-slide images of almost any round or oval organ.",10.105566/ias.2791

The FL capability is especially important to domains such as biomedicine and smart grid, where data may not be shared freely or stored at a central location because of policy regulations. Thanks to the capability of learning from decentralized datasets, FL is now a rapidly growing research field, and numerous FL frameworks have been developed. In this work we introduce APPFL, the Argonne Privacy-Preserving Federated Learning framework. APPFL allows users to leverage implemented privacy-preserving algorithms, implement new algorithms, and simulate and deploy various FL algorithms with privacy-preserving techniques. The modular framework enables users to customize the components for algorithms, privacy, communication protocols, neural network models, and user data. We also present a new communication-efficient algorithm based on an inexact alternating direction method of multipliers.

However, as the data becomes more complex and larger, SQL data processing becomes more difficult and costly. Typical problems include changing SQL queries and data schema resolution in complex dependencies by hand. In addition, human errors can lead to complex cyclic dependency problems. To mitigate these problems, we developed AlphaSQL: an open-source software tool for SQL data processing. AlphaSQL mainly supports three techniques to automate data preparation by SQL: (1) extracting a directed acyclic graph (DAG) based on dependencies between SQL and data, (2) validating the schema included in the whole DAG, and (3) parallelizing the queries based on the DAG. We applied AlphaSQL to a real-world data analysis and machine learning project where we analyzed 1445 logs obtained from static validation for git commits and 3243 execution logs. Our analysis showed that AlphaSQL detected various errors with high precision and recall, part of which existing tools could not catch (e.g., missing resources and schema mismatches).

While 3DP has gained tremendous popularity, it remains a daunting and perceptibly time-consuming process for the inexperienced user, with most turning to commercially printed products. Commercial vendors are expensive. We propose that 3DP is feasible for the inexperienced user with the appropriate knowledge and tools.Methods: A 3DP protocol was created for model design and printing using open-source software and a low-cost desktop printer. It was betatested by 3 inexperienced users. The fidelity of the protocol was then tested in direct comparison to industry models made for 3 patients undergoing mandibular distraction osteogenesis, using standard cephalometric measurements.Results: All inexperienced testers were able to successfully create a 3D model using the easy-to-follow protocol without the use of any other resources. The models were created in a mean time of 170 minutes. All cephalometric measurements on the open-source printed models were equal to within 0.5 to 1.0 mm of the respective industry models.Conclusions: As the 3DP process is simplified and desktop printers and materials become more affordable, we anticipate that its implementation will become more commonplace.

Notwithstanding the strengths of GEs, they lack support for many common GIS file formats, and there exist only limited georeferencing possibilities. Visualizing large-scale geolocations involves high authoring costs, and the shortcomings of GEs further complicate the workflow. In this paper, we present a workflow and its implementation for creating large immersive virtual environments that accurately represent real-world urban areas. The benefits of the presented development are threefold. First, it makes the process more efficient by automating multiple steps and incorporating a large portion of the workflow inside the GE. Second, it facilitates an interactive framework by allowing the developer to efficiently extend the scene components with functionalities and interactions. Third, it entirely relies on open-source software and data, making it suitable for many non-commercial domains.

+1629,Article,An analysis of open source software licensing questions in Stack Exchange sites,"Free and open source software is widely used in the creation of software systems, whereas many organizations choose to provide their systems as open source. Open source software carries licenses that determine the conditions under which the original software can be used. Appropriate use of licenses requires relevant expertise by the practitioners, and has an important legal angle. Educators and employers need to ensure that developers have the necessary training to understand licensing risks and how they can be addressed. At the same time, it is important to understand which issues practitioners face when they are using a specific open source license, when they are developing new open source software products or when they are reusing open source software. In this work, we examine questions posed about open source software licensing using data from the following Stack Exchange sites: Stack Overflow, Software Engineering, Open Source and Law. We analyze the indication of specific licenses and topics in the questions, investigate the attention the posts receive and trends over time, whether appropriate answers are provided and which type of questions are asked. Our results indicate that practitioners need, among other, clarifications about licensing specific software when other licenses are used, and for understanding license content. The results of the study can be useful for educators and employers, organizations that are authoring open source software licenses and developers for understanding the issues faced when using licenses, whereas they are relevant to other software engineering research areas, such as software reusability.

Open source licenses such as GPL, MIT, Apache, Mozilla, BSD, etc have varying terms and conditions for usage, modification, and distribution. Given the availability of source code for open source software, it is difficult to scrutinize adherence of licenses and more often than not it is left to the good faith of organizations and individuals. Violation of licensing terms knowingly or unknowingly can lead to copyright, ethical, compliance and security issues. In this paper, we propose a blockchain based approach in managing open source software licenses by enforcing certain practices to improve awareness and increase transparency, thus minimizing the possibility of violations.

GNSS is a high-accuracy technique that is widely used today for monitoring and detecting deformations in the earth's crust and engineering structures. However, difficulties are encountered in the evaluation of measurements due to the intensive use of statistics in deformation analysis and the high numerical calculation load. Considering the possible consequences of deformations in the earth's crust and engineering structures, strategies and evaluation software are needed to determine them quickly. In this study, an open-source software that can be used in the analysis of deformation surveys carried out in campaigns with the static GNSS technique were developed by using R programming language since open-source deformation analysis software is missing in the field of deformation analysis. The method chosen for the determination of deformations is presented. The general features of the developed software are introduced, and a case study was carried out to test the computational performance of the software and to investigate which parameters are effective in determining the amount of deformation in GNSS networks correctly. As a result of the study, it was seen that ambiguity resolution rates and ionospheric activity affect the accuracy of the deformations determined in GNSS networks.",10.1007/s12145-022-00844-1
+1632,Article,An open-source software framework for reinforcement learning-based control of tracked robots in simulated indoor environments,"A simulation framework based on the open-source robotic software Gazebo and the Robot Operating System is presented for articulated tracked robots, designed for reinforcement-learning-based (RL) control skill acquisition. In particular, it is destined to serve as a research tool in the development and evaluation of methods in the domain of mobility learning for articulated tracked robots, in 3D indoor environments. Its architecture allows to interchange between different RL libraries and algorithm implementations, while learning can be customized to endow specific properties within a control skill. To demonstrate its utility, we focus on the most demanding case of staircase ascent and descent using depth image data, while respecting safety via reward function shaping and incremental, domain randomization-based, end-to-end learning.",10.1080/01691864.2022.2076570
+1633,Article,An operational land cover and land cover change toolbox: processing open-source data with open-source software,"Accurate and up-to-date land cover maps are vital for underpinning evidence-based landscape management decision-making. However, the technical skills required to extract tailored information about land cover dynamics from these open-access geospatial data often limit their use by those making landscape management decisions. Using Dartmoor National Park as an example, we demonstrate an open-source toolkit which uses open-source software (QGIS and RStudio) to process freely available Sentinel-2 and public LiDAR data sets to produce fine scale (10 m(2) grain size) land cover maps. The toolbox has been designed for use by staff within the national park, for example, enabling land cover maps to be updated as required in the future. An area of 945 km(2) was mapped using a trained random forest classifier following a classification scheme tailored to the needs of the national park. A 2019 land cover map had an overall user's accuracy of 79\\%, with 13 out of 17 land cover classes achieving greater than 70\\% accuracy. Spatially, accuracy was related via logistical regression to blue band surface reflectance in the spring and topographic slope derived from LiDAR (1 m resolution), with greater accuracy in steeper terrain and areas exhibiting higher blue reflectance. Between an earlier (2017-2019) and later (2019-2021) time frame, 8\\% of pixels changed, most of the change by area occurred in the most common classes. However, the largest proportional increase occurred in Upland Meadows, Lowland Meadows and Blanket Bog, all habitats subject to restoration efforts. Identifying areas of change enables future field work to be better targeted. We discuss the application of this mapping to land management within the Dartmoor national park and of the potential of tailored land cover and land cover change mapping, via this toolbox, to evidence-based environmental decision-making more widely.",10.1002/2688-8319.12162
+1634,InProceedings,Analyzing the Relationship between Community and Design Smells in Open-Source Software Projects: An Empirical Study,"Background: Software smells reflect the sub-optimal patterns in the software. In a similar way, community smells consider the sub-optimal patterns in the organizational and social structures of software teams. Related work performed empirical studies to identify the relationship between community smells and software smells at the architecture and code levels. However, how community smells relate with design smells is still unknown. Aims: In this paper, we empirically investigate the relationship between community smells and design smells during the evolution of software projects. Method: We apply three statistical methods: correlation, trend, and information gain analysis to empirically examine the relationship between community and design smells in 100 releases of 10 large-scale Apache open-source software projects. Results: Our results reveal that the relationship between community and design smells varies across the analyzed projects. We find significant correlations and trend similarities for one type of community smell (when developers work in isolation without peer communication-Missing Links) with design smells in most of the analyzed projects. Furthermore, the results of our statistical model disclose that community smells are more relevant for design smells compared to other community-related factors. Conclusion: Our results find that the relationship of community smells (in particular, the Missing Links smell) exists with design smells. Based on our findings, we discuss specific community smell refactoring techniques that should be done together when refactoring design smells so that the problems associated with the social and technical (design) aspects of the projects can be managed concurrently.",10.1145/3544902.3546249
+1636,InProceedings,Attracting and Retaining OSS Contributors with a Maintainer Dashboard,"Tools and artifacts produced by open source software (OSS) have been woven into the foundation of the technology industry. To keep this foundation intact, the open source community needs to actively invest in sustainable approaches to bring in new contributors and nurture existing ones. We take a first step at this by collaboratively designing a maintainer dashboard that provides recommendations on how to attract and retain open source contributors. For example, by highlighting project goals (e.g., a social good cause) to attract diverse contributors and mechanisms to acknowledge (e.g., a ``rising contributor{''} badge) existing contributors. Next, we conduct a project-specific evaluation with maintainers to better understand use cases in which this tool will be most helpful at supporting their plans for growth. From analyzing feedback, we find recommendations to be useful at signaling projects as welcoming and providing gentle nudges for maintainers to proactively recognize emerging contributors. However, there are complexities to consider when designing recommendations such as the project current development state (e.g., deadlines, milestones, refactoring) and governance model. Finally, we distill our findings to share what the future of recommendations in open source looks like and how to make these recommendations most meaningful over time.",10.1145/3510458.3513020
+1641,Article,BlenderPhotonics: an integrated open-source software environment for three-dimensional meshing and photon simulations in complex tissues,"Significance: Rapid advances in biophotonics techniques require quantitative, model-based computational approaches to obtain functional and structural information from increasingly complex and multiscaled anatomies. The lack of efficient tools to accurately model tissue structures and subsequently perform quantitative multiphysics modeling greatly impedes the clinical translation of these modalities. Aim: Although the mesh-based Monte Carlo (MMC) method expands our capabilities in simulating complex tissues using tetrahedral meshes, the generation of such domains often requires specialized meshing tools, such as Iso2Mesh. Creating a simplified and intuitive interface for tissue anatomical modeling and optical simulations is essential toward making these advanced modeling techniques broadly accessible to the user community. Approach: We responded to the above challenge by combining the powerful, open-source three-dimensional (3D) modeling software, Blender, with state-of-the-art 3D mesh generation and MC simulation tools, utilizing the interactive graphical user interface in Blender as the front-end to allow users to create complex tissue mesh models and subsequently launch MMC light simulations. Results: Here, we present a tutorial to our Python-based Blender add-on-BlenderPhotonics- to interface with Iso2Mesh and MMC, which allows users to create, configure and refine complex simulation domains and run hardware-accelerated 3D light simulations with only a few clicks. We provide a comprehensive introduction to this tool and walk readers through five examples, ranging from simple shapes to sophisticated realistic tissue models. Conclusions: BlenderPhotonics is user friendly and open source, and it leverages the vastly rich ecosystem of Blender. It wraps advanced modeling capabilities within an easy-to-use and interactive interface. The latest software can be downloaded at http://mcx.space/bp. (C) The Authors.

+1642,Article,CMRSegTools: An open-source software enabling reproducible research in segmentation of acute myocardial infarct in CMR images,"In the last decade, a large number of clinical trials have been deployed using Cardiac Magnetic Resonance (CMR) to evaluate cardioprotective strategies aiming at reducing the irreversible myocardial damage at the time of reperfusion. In these studies, segmentation and quantification of myocardial infarct lesion are often performed with a commercial software or an in-house closed-source code development thus creating a barrier for reproducible research. This paper introduces CMRSegTools: an open-source application software designed for the segmentation and quantification of myocardial infarct lesion enabling full access to state-of-the-art segmentation methods and parameters, easy integration of new algorithms and standardised results sharing. This post-processing tool has been implemented as a plug-in for the OsiriX/Horos DICOM viewer leveraging its database management functionalities and user interaction features to provide a bespoke tool for the analysis of cardiac MR images on large clinical cohorts. CMRSegTools includes, among others, user-assisted segmentation of the left-ventricle, semi- and automatic lesion segmentation methods, advanced statistical analysis and visualisation based on the American Heart Association 17-segment model. New segmentation methods can be integrated into the plug-in by developing components based on image processing and visualisation libraries such as ITK and VTK in C++ programming language. CMRSegTools allows the creation of training and testing data sets (labeled features such as lesion, microvascular obstruction and remote ROI) for supervised Machine Learning methods, and enables the comparative assessment of lesion segmentation methods via a single and integrated platform. The plug-in has been successfully used by several CMR imaging studies.",10.1371/journal.pone.0274491
+1643,InProceedings,Characterizing Technical Debt in Evolving Open-source Software,"Technical debt represents deficiencies in software design or implementation often caused by prioritizing feature development over fixing existing issues. Like its financial counterpart, technical debt comprises a principal and an interest. Not addressing it in time leads to development crises, where focus and resources must be shifted to address existing issues. Existing software tools allow measuring the level of debt and pinpointing its sources, which can help practitioners control it. In the present paper we aim to investigate the prevalence, characteristics, and evolution of technical debt in several open-source applications. We used SonarQube to study 112 application versions that covered more than 15 years of development for each application. We studied the way debt characteristics and source code distribution evolved over the target applications' lifecycles. We addressed concerns regarding the accuracy of the analysis and illustrated some of the limitations of existing tools. We observed that a small number of issue types were responsible for most of the debt. We found that each application had its own technical debt particularities. As future work, we aim to expand our selection of analysis tools, leverage open data sets, and extend our investigation to other systems and types of software.",10.5220/0011073600003176
+1644,InProceedings,Characterizing User Behaviors in Open-Source Software User Forums: An Empirical Study,"User forums of Open Source Software (OSS) enable end-users to collaboratively discuss problems concerning the OSS applications. Despite decades of research on OSS, we know very little about how end-users engage with OSS communities on these forums, in particular, the challenges that hinder their continuous and meaningful participation in the OSS community. Many previous works are developer-centric and overlook the importance of end-user forums. As a result, end-users' expectations are seldom reflected in OSS development. To better understand user behaviors in OSS user forums, we carried out an empirical study analyzing about 1.3 million posts from user forums of four popular OSS applications: Zotero, Audacity, VLC, and RStudio. Through analyzing the contribution patterns of three common user types (end-users, developers, and organizers), we observed that end-users not only initiated most of the threads (above 96\\% of threads in three projects, 86\\% in the other), but also acted as the significant contributors for responding to other users' posts, even though they tended to lack confidence in their activities as indicated by psycho-linguistic analyses. Moreover, we found end-users more open, reflecting a more positive emotion in communication than organizers and developers in the forums. Our work contributes new knowledge about end-users' activities and behaviors in OSS user forums that the vital OSS stakeholders can leverage to improve end-user engagement in the OSS development process.",10.1145/3528579.3529178

+1647,Article,Code comment generation based on graph neural network enhanced transformer model for code understanding in open-source software ecosystems,"In open-source software ecosystems, the scale of source code is getting larger and larger, and developers often use various methods (good code comments or method names, etc.) to make the code easier to read and understand. However, high-quality code comments or method names are often unavailable due to tight project schedules or other reasons in open-source software ecosystems such as Github. Therefore, in this work, we try to use deep learning models to generate appropriate code comments or method names to help software development and maintenance, which requires a non-trivial understanding of the code. Therefore, we propose a Graph neural network enhanced Transformer model (GTrans for short) to learn code representation to understand code better. Specifically, GTrans learns code representation from code sequences and graphs. We use a Transformer encoder to capture the global representation from code sequence and a graph neural network (GNN) encoder to focus on the local details in the code graph, and then use a decoder to combine both global and local representations by attention mechanism. We use three public datasets collected from GitHub to evaluate our model. In an extensive evaluation, we show that GTrans outperforms the state-of-the-art models up to 3.8\\% increase in METEOR metrics on code comment generation and outperforms the state-of-the-art models by margins of 5.8\\%-9.4\\% in ROUGE metrics on method name generation after some adjustments on the structure. Empirically, we find the method name generation task depends on more local information than global, and the code comment generation task is in contrast.

We investigated 355 F/OSS software package websites for the presence of codes of conduct and then analyzed these for diversity elements. Qualitative content analysis of the websites shows that less than 10\\% (28) of the analyzed websites had some type of community rules such as CoC. In-depth analysis of the CoCs demonstrated many discrepancies in the terminology, length, enforcement, and adoption of codes of conduct. To investigate the usage of these CoCs, we investigate five women-focused OSS discussion forums. This analysis shows the value of creating/adopting a CoC and the impact CoC can have on the participation of women. We also present the challenges in the usage and enforcement of CoCs as discussed by women of these forums. We conclude with recommendations for better enforcement of CoC and reflection on the ethical underpinnings of CoC as a tool to improve diversity and inclusion in OSS.",10.1007/s11219-020-09543-w

Whether in operating systems, network stacks, or as low-level system drivers, software we encounter daily is permeated with code contributions from open source projects. Decentralized development and open collaboration in open source projects introduce unique challenges: code submissions from unknown entities, limited personpower for commit or dependency reviews, and bringing new contributors up-to-date in projects' best practices \\& processes. In 27 in-depth, semi-structured interviews with owners, maintainers, and contributors from a diverse set of open source projects, we investigate their security and trust practices. For this, we explore projects' behind-the-scene processes, provided guidance \\& policies, as well as incident handling \\& encountered challenges. We find that our participants' projects are highly diverse both in deployed security measures and trust processes, as well as their underlying motivations. Based on our findings, we discuss implications for the open source software ecosystem and how the research community can better support open source projects in trust and security considerations. Overall, we argue for supporting open source projects in ways that consider their individual strengths and limitations, especially in the case of smaller projects with low contributor numbers and limited access to resources.",10.1109/SP46214.2022.00143

These projects are largely created and maintained by unpaid volunteers, presenting a potential vulnerability if the projects cannot recruit and retain new volunteers. At the same time, their development on open collaborative development platforms provides a nearly complete record of the community's interactions; this affords the opportunity to study naturally occurring language dynamics at scale and in a context with massive real-world impact. The present work takes a dynamical systems view of language to understand the ways in which communicative context and community membership shape the emergence and impact of language use-specifically, sentiment and expressions of gratitude. We then present evidence that these language dynamics shape newcomers' likelihood of returning, although the specific impacts of different community responses are crucially modulated by the context of the newcomer's first contact with the community.",10.1111/cogs.13134

Although this data source has weaknesses, this involvement in the research process has considerable pedagogical value in teaching students research methodology. Statement of the Problem Most common software packages used to manage participant pools tend to be expensive, to the extent that it prohibits access for small institutions and departments. Literature Review Highlighting the problem, we cite research related to using undergraduates as participants, pedagogical value of these experiences, and current trends in software distribution. We then provide evidence of successful implementation of open-source software (OSS) in educational settings, and conclude with OSS options capable of addressing the problem of access. Teaching Implications By providing students research experiences, both as a researcher and as a participant, we enhance their understanding of this process.

+1656,Article,Cui Bono: Do Open Source Software Incubator Policies and Procedures Benefit the Projects or the Incubator?,"Open source software (OSS), a form of Digital or Knowledge Commons, underlies much of the technology that we use in our daily lives. The existence and continuation of OSS relies on the contribution of private resources - personal time, volunteer energy, and effort of numerous actors (e.g., software developers' time as a common-pool resource) - to public goods, the benefits of which are enjoyed by everyone. Nonprofit organizations such as the Apache Software Foundation (ASF) attempt to aid this process by providing various collective services to OSS projects, acting as a second-order actor in the production of the public good. To this end, the ASF Incubator has created policies - essentially rules or norms - that serve to protect its interests and, as they say, increase the sustainability of the projects. Each policy requires investment by ASF (in terms of money or the use of volunteer time) or an incubating project (in terms of taking project personnel time), the benefits of which can accrue to either party. Such policies may impose additional costs on incubating projects, leading to a decreased production of the OSS public good. Using the ASF Incubator policy documents, we construct a dataset that records who - ASF or an incubating project - bears the cost and who enjoys the benefit of each policy and procedure. We can code most policy statements as costing one party and benefiting one party. The distribution of costs and benefits according to party indicates whether the second-order actor is contributing to an increase in the public good and if they are doing so sustainably. Through a two-way ANOVA, we characterize the impact of ASF policies on the production of public goods (OSS). Being a part of ASF imposes some costs on projects, but these costs may make projects more sustainable. Our analysis shows that the distribution of costs and benefits is fairly symmetric between the ASF and incubating projects. Thus, the configuration of policies or the ``institutional design{''} of the ASF could aid in producing the OSS public good by providing services that projects require.",10.5334/ijc.1176

This archetype of OSS development is distinct from other types that include organizations, yet is understudied. As organizations increasingly contribute to and rely on OSS as part of their strategy, understanding how they can collaborate to build software holds importance for the future of software development. This study collects a unique dataset of development tasks from a large orgsOSS project spanning over two years and seven releases. Building on existing OSS research, we explore norms with respect to collaboration, i.e., how developers assign, discuss, and complete tasks, in an orgsOSS project. Interestingly, our analysis reveals that developers in orgsOSS do not always adhere to ideals of widespread sharing and participation espoused by traditional OSS, however some developer and task characteristics helped foster these ideals. Based on these and other findings, we develop a set of propositions and associated collaboration mechanisms that are important to future orgsOSS and other similarly structured software development projects.",10.1109/TSE.2021.3108935

+1661,Article,Development of a REDCap-based workflow for high-volume relational data analysis on real-time data in a medical department using open source software,"Background/Aim: The current availability of large volumes of clinical data has provided medical departments with the opportunity for large-scale analyses, but it has also brought forth the need for an effective strategy of data-storage and data-analysis that is both technically feasible and economically sustainable in the context of limited resources and manpower. Therefore, the aim of this study was to develop a widely-usable data-collection and data-analysis workflow that could be applied in medical departments to perform high-volume relational data analysis on real-time data. Methods: A sample project, based on a research database on prostate-specific-membrane-antigen/positron-emission-tomography scans performed in prostate cancer patients at our department, was used to develop a new workflow for data-collection and data-analysis. A checklist of requirements for a successful data-collection/analysis strategy, based on shared clinical research experience, was used as reference standard. Software libraries were selected based on widespread availability, reliability, cost, and technical expertise of the research team (REDCap-v11.0.0 for collaborative data-collection, Python-v3.8.5 for data retrieval and SQLite-v3.31.1 for data storage). The primary objective of this study was to develop and implement a workflow to: a) easily store large volumes of structured data into a relational database, b) perform scripted analyses on relational data retrieved in real-time from the database. The secondary objective was to enhance the strategy cost-effectiveness by using open-source/cost-free software libraries. Results: A fully working data strategy was developed and successfully applied to a sample research project. The REDCap platform provided a remote and secure method to collaboratively collect large volumes of standardized relational data, with low technical difficulty and role-based access-control. A Python software was coded to retrieve live data through the REDCap-API and persist them to an SQLite database, preserving data-relationships. The SQL-language enabled complex datasets retrieval, while Python allowed for scripted data computation and analysis. Only cost-free software libraries were used and the sample code was made available through a GitHub repository. Conclusions: A REDCap-based data-collection and data-analysis workflow, suitable for high-volume relational data-analysis on live data, was developed and successfully implemented using open-source software.

+1665,Article,Dnabarcoder: An open-source software package for analysing and predicting DNA sequence similarity cutoffs for fungal sequence identification,"The accuracy and precision of fungal molecular identification and classification are challenging, particularly in environmental metabarcoding approaches as these often trade accuracy for efficiency given the large data volumes at hand. In most ecological studies, only a single similarity cutoff value is used for sequence identification. This is not sufficient since the most commonly used DNA markers are known to vary widely in terms of inter- and intraspecific variability. We address this problem by presenting a new tool, dnabarcoder, to predict local similarity cutoffs and measure the resolving powers of a biomarker for sequence identification for different clades of fungi. It was shown that the predicted similarity cutoffs varied significantly between the clades of a recently released ITS DNA barcode data set from the CBS culture collection of the Westerdijk Fungal Biodiversity Institute. When classifying a large public fungal ITS data set-the UNITE database-against the barcode data set, the local similarity cutoffs assigned fewer sequences than the traditional cutoffs used in metabarcoding studies. However, the obtained accuracy and precision were significantly improved. Our study showed that it might be better to extract the ITS region from the ITS barcodes to optimize taxonomic assignment accuracy. Furthermore, 15.3, 25.6, and 26.3\\% of the fungal species of the barcode data set were indistinguishable by full-length ITS, ITS1, and ITS2, respectively. Except for these indistinguishable species, the resolving powers of full-length ITS, ITS1, and ITS2 sequences were similar at the species level. Nevertheless, the complete ITS region had a better resolving power at higher taxonomic levels.",10.1111/1755-0998.13651

In this study, our objective was to advance the practicality of drug-coated floss as an intra gum pocket drug delivery system. The initial design of this delivery system has been previously reported by us. Here, we advance the concept further through in vitro and in vivo evaluation. A floss piece was dip coated in the middle section with model molecules leaving free ends for holding. Porcine gum tissues were used ex vivo and in vivo to evaluate the coated floss, including effect of coating thickness on delivery efficiency, ability to deliver more than one type of molecule (one hydrophilic and one hydrophobic), mechanical properties using a scratch test, and finally retention of delivered material in vivo in the porcine model. After reaching a certain coating thickness, the delivery efficiency of the coated floss decreased, indicating the presence of an optimal coating thickness. Hydrophobic and hydrophilic molecules were successfully coated and delivered with high efficiency into gum pockets. The scratch test indicated that the coatings were resilient. Lastly, the in vivo analysis showed that the drug coating was delivered into the porcine gum pocket with about 65\\% efficiency, and the coatings could maintain extended residency within the gum pocket despite the native adverse environment of the oral cavity. Overall, this data shows that drug-coated floss can act as a drug delivery vehicle and has potential to provide a minimally invasive and practical method for the delivery of drugs into the gum pockets.",10.1021/acsami.2c07976

Findings This paper found that FOSS has become an important research area and is playing an important role in the reform and development of education. Meanwhile, the development and application of FOSS have regional imbalances and strong differentiation, including the educational sector. The paper also found that although FOSS has entered the stage of interdisciplinary development, the research and development of FOSS in the field of education is insufficient, which poses a huge challenge to decision-makers, teachers and students. Originality/value Implications for higher education in Hong Kong including: attach importance to and vigorously promote FOSS research and practice to benefit more teachers and students; teachers and students need to be trained for acquiring the awareness and skills of FOSS applications and formulate different strategies; the government should provide greater support to formulate and implement a short and middle-term development plan to facilitate the application of FOSS; and Hong Kong higher education institutions may strengthen exchanges and cooperation with counterparts around the world to jointly promote the development of FOSS. It is hoped that the findings will provide a reference for the study and application of FOSS in higher education in Hong Kong.",10.1108/ITSE-11-2020-0223

Because its code is open to the public, it has been pursued by programming teams all over the world, including those in universities, government agencies and enterprises. In addition to analyzing some famous OSS projects, researchers also studied OSS projects and their functions in GitHub. However, the evolution process and the rules of OSS projects in GitHub have not been widely investigated so we conducted in-depth research on this issue. We use the cellular automata (CA) in the field of system dynamics to model the OSS project, construct the evolution rules of the Gray wolf optimization (GWO) algorithm, define the objective vector, objective function and key optimization operators of GWO for OSS cellular evolution, and realize the intelligent acquisition of OSS project evolution rules in GitHub. In addition, we also selected the data of some OSS projects in GitHub from 2015 to 2020 for the simulation experiment.

+1672,Article,"Evolving collaboration, dependencies, and use in the Rust Open Source Software ecosystem","Open Source Software (OSS) is widely spread in industry, research, and government. OSS represents an effective development model because it harnesses the decentralized efforts of many developers in a way that scales. As OSS developers work independently on interdependent modules, they create a larger cohesive whole in the form of an ecosystem, leaving traces of their contributions and collaborations. Data harvested from these traces enable the study of large-scale decentralized collaborative work. We present curated data on the activity of tens of thousands of developers in the Rust ecosystem and the evolving dependencies between their libraries. The data covers eight years of developer contributions to Rust libraries and can be used to reconstruct the ecosystem's development history, such as growing developer collaboration networks or dependency networks. These are complemented by data on downloads and popularity, tracking dynamics of use, visibility, and success over time. Altogether the data give a comprehensive view of several dimensions of the ecosystem.",10.1038/s41597-022-01819-z

Experimental and, to a lesser extent, rigorous simulation papers concerning these processes have been widely considered and discussed in the literature. Nonetheless, there is still a gap to fill in providing a fast and reliable simulation scheme. In this paper, an efficient simulation strategy, combining the free-software COCO simulator for the bio-waste slow pyrolysis coupled with commercial SimaPro code to carry out the Life Cycle Assessment (LCA), was applied. The pyrolysis product yields at 673, 773, and 873 K were well predicted using mass and energy balances and a proposed reaction scheme from the literature. Simulations were validated using experimental data previously reported. The highest yield was 53.7\\% for biochar (673 K - stalk of white grape), 32\\% for bio-oil (773 K -marc of red grape), and 56.3\\% for gas (873 K -marc of white grape).

However, there has been limited research on developers' abandonment, though it is found to have detrimental effect on quality and sustainability of OSS projects. This paper examines the impact of developer and project-related factors on developer abandonment in OSS projects. Factors include developer attributes: experience, role, coding language, and joining date, and project attributes: change complexity and sentiments in commit logs. The findings are (1) for developer experience, core/non-core member, and joining date; there exists a pattern of developers abandoning the projects. (2) There is no definite answer for coding language. (3) It does not relate to the change profile of a project except a few indicators. Sentiments can also not be linked.

+1677,InProceedings,Exploring trends and practices of forks in open-source software repositories,"Forking a software repository is a popular and recommended practice among developers. A fork is a copy of the original repository that can evolve independently from the parent repository, allowing developers to experiment with a code base or test new features without the danger of affecting the original project. A fork can result in changes that are pushed back to the original project or even evolve into an independent project. Some projects tend to be forked extensively to the point where their forks are also forked and form families of projects. In this work, we explore the motivation, the practices and the culture of forking open-source software repositories. In particular, we study how forks evolve compared to the parent repository, how they are related to pull requests, how they contribute back to the parent, and how dependencies, in terms of libraries or external modules defined in a build script, are shared or differ within project families. Finally, we relate our findings with how communication and collaboration occurs within software families.",NA
+1678,Article,Fabrication and characterization of tea polyphenol W/O microemulsion-based bioactive edible film for sustained release in fish floss preservation,"A coated nanoemulsion (CNE)-based edible film was fabricated on the surface of fish floss (FF) to extend its shelf life during storage. The antioxidant tea polyphenol (TPP) was embedded into W/O microemulsion, which was further encapsulated into multiple emulsion (Multi-E) together with functional soluble dietary fiber (SDF). The physicochemical properties indicated that the nanoemulsion-based edible film (NEF) improved the morphology of FF and reduced the crystallinity of the film by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The water vapor permeability increased gradually and rose to only 0.99\\% after 5 h, resulting in the water activity of FF at a low level (<= 0.51) during the storage period. The TPP inside was released at a constant rate (<= 18.10\\%) on the surface, and such a rate was accelerated in the simulated gastrointestinal environment, especially in intestine reaching 60.12\\% after 5 h of digestion. Besides, the effect of NEF on the flavor was also evaluated and the contents of ketones, phenols, and pyrazines increased, which displayed a regulating effect on the overall flavor of FF by blocking the external moisture and suppressing the microorganism activity. In summary, the NEF effectively enhanced the flavor and taste of FF, controlled the release of TPP, and reduced the water activity during the storage, thereby extending the shelf life.",10.1002/fsn3.2845
+1681,InProceedings,Follow the Leader: Technical and Inspirational Leadership in Open Source Software,"We conduct the first comprehensive study of the behavioral factors which predict leader emergence within open source software (OSS) virtual teams. We leverage the full history of developers' interactions with their teammates and projects at github.com between January 2010 and April 2017 (representing about 133 million interactions) to establish that - contrary to a common narrative describing open source as a pure ``technical meritocracy{''} - developers' communication abilities and community building skills are significant predictors of whether they emerge as team leaders. Inspirational communication therefore appears as central to the process of leader emergence in virtual teams, even in a setting like OSS, where technical contributions have often been conceptualized as the sole pathway to gaining community recognition. Those results should be of interest to researchers and practitioners theorizing about OSS in particular and, more generally, leadership in geographically dispersed virtual teams, as well as to online community managers.",10.1145/3491102.3517516
+1683,Article,Free and open source software for computational chemistry education,"After decades of waiting, computational chemistry for the masses is finally here. Our brief review on free and open source software (FOSS) packages points out the existence of software offering a wide range of functionality, all the way from approximate semiempirical calculations with tight-binding density functional theory to sophisticated ab initio wave function methods such as coupled-cluster theory, covering both molecular and solid-state systems. Combined with the remarkable increase in the computing power of personal devices, which now rivals that of the fastest supercomputers in the world in the 1990s, we demonstrate that a decentralized model for teaching computational chemistry is now possible thanks to FOSS packages, enabling students to perform reasonable modeling on their own computing devices in the bring your own device (BYOD) scheme. FOSS software can be made trivially simple to install and keep up to date, eliminating the need for departmental support, and also enables comprehensive teaching strategies, as various algorithms' actual implementations can be used in teaching. We exemplify what kinds of calculations are feasible with four FOSS electronic structure programs, assuming only extremely modest computational resources, to illustrate how FOSS packages enable decentralized approaches to computational chemistry education within the BYOD scheme. FOSS also has further benefits driving its adoption: the open access to the source code of FOSS packages democratizes the science of computational chemistry, and FOSS packages can be used without limitation also beyond education, in academic and industrial applications, for example.

Although there is a good body of literature on open source participation, there is very little understanding of the participation trajectories and contribution experiences of women developers, and how they compare to those of men developers, in open source software projects. In order to understand their joining and participation trajectories, we conducted interviews with 23 developers (11 men and 12 women) who became core in an open source project. We identify differences in women and men's motivations for initial contributions and joining processes (e.g. women participating in projects that they have been invited to) and sustained involvement in a project. We also describe unique negative experiences faced by women contributors in this setting in each stage of participation.

+1689,Article,HSI-PP: A flexible open-source software for hyperspectral imaging-based plant phenotyping,"Hyperspectral imaging has become one of the most popular techniques for high-throughput plant phenotyping. Extracting and analyzing useful plant phenotypic traits from hyperspectral images represents a major bottleneck for plant science and breeding communities. This study aims to present a stand-alone easy-to-use software platform called HSI-PP to process and analyze hyperspectral images for high-throughput plant phenotyping. The HSI-PP software integrates pre-processing, feature extraction, and modeling functions. The application of HSI-PP is exemplified by investigating the response of different Arabidopsis thaliana genotypes to drought stress, and the impact of various imaging angles on predicting the canopy nitrogen content (CNC) of oilseed rape (Brassica napus L.). The results showed that HSI-PP can process 10 GB on an ordinary PC in time ranging from 30 to 73 min according to image size and the complexity of the pipeline. HSI-PP extracted multiple phenotyping traits (spectral, textural, and morphological) of Arabidopsis thaliana from a large image dataset (104 GB) within five hours. The fusion of these features achieved higher accuracy (94\\%) than only using spectral information (85\\%) as early as day 4 after drought stress treatment. For oilseed rape, about 384 GB image data was processed within eighteen hours, and it was found that the tilted imaging angle of 75 had the optimized PLSR fitting (0.83) to the ground truth. The results demonstrate that HSI-PP is a stand-alone, automated, and open-source hyperspectral image processing platform adapted to various applications in plant phenotyping without requiring professional programming skills to serve the plant research community.",10.1016/j.compag.2022.107248

The empirical corpus selected for this work is built upon a series of interviews with free software activists and records of participant observation in events promoted by the communities of which the interviewees are part. A close look at their experiences allows us to recognize a set of commonalities that converge in a process in which they rewrite and resignify the principles that have historically been assigned to `hacker learning'.

In this context, developers come across various issues they need to handle in order to use and create software responsibly and without causing legal violations. For instance, using open source software that carries a specific license or how contributions to open source software should be handled are among the issues that need to be considered.Objective: As practitioners turn primarily to Q\\&A sites to seek help, it is important to understand which specific open source software issues they face. In this research, our main objective is to provide a categorization of open source software problems present in the user questions of the Open Source Stack Exchange site and perform a meta-analysis on the encountered questions.Method: We have performed a qualitative study analyzing manually 1,500 most popular posts in the Open Source Stack Exchange site and have mapped them to categories and more generic clusters. The coding task was performed in iterations with the participation of three of the authors. Agreement was calculated and cases of disagreement were resolved. Meta-analysis on questions and answers was also performed for discussion purposes.Results: We have created 26 categories of problems discussed in the Open Source Stack Exchange site, and grouped them into 6 clusters. Our results show that posts on license texts/conditions and license/copyright notices are more common, whereas posts on license differences are the most popular in terms of views by other users.Conclusion: The results can assist any participant of the open source software community to understand on which basic issues she should focus on to gain a good understanding of open source software.

However, onboarding to an OSS project brings various challenges, including finding a suitable task among various open issues. Selecting an appropriate starter task requires newcomers to identify the skills needed to solve a project issue and avoiding tasks too far from their skill set. However, little is known about how effective newcomers are in identifying the skills needed to resolve an issue. We asked 154 undergrad students to evaluate issues from OSS projects and infer the skills needed to contribute. Students reported a total of 94 skills, which we classified into 10 categories. We compared the students' answers to those collected from 6 professional developers. In general, students misidentified and missed several skills (f-measure=0.37). Students had results closer to professional developers for skills related to database, operating infrastructure, programming concepts, and programming language, and they had worse results in identifying skills related to debugging and program comprehension.

However, this research has focused mainly on social/cultural factors, neglecting the software tools and infrastructure. To shed light on how OSS tools and infrastructure might factor into OSS barriers to entry, we conducted two studies: (1) a field study with five teams of software professionals, who worked through five use cases to analyze the tools and infrastructure used in their OSS projects; and (2) a diary study with 22 newcomers (9 women and 13 men) to investigate whether the barriers matched the ones identified by the software professionals. The field study produced a bleak result: software professionals found gender biases in 73 percent of all the newcomer barriers they identified. Further, the diary study confirmed these results: Women newcomers encountered gender biases in 63 percent of barriers they faced. Fortunately, many kinds of barriers and biases revealed in these studies could potentially be ameliorated through changes to the OSS software environments and tools.",10.1109/TSE.2020.2984173
+1694,InProceedings,How Long Do Vulnerabilities Live in the Code? A Large-Scale Empirical Measurement Study on FOSS Vulnerability Lifetimes,"How long do vulnerabilities live in the repositories of large, evolving projects? Although the question has been identified as an interesting problem by the software community in online forums, it has not been investigated yet in adequate depth and scale, since the process of identifying the exact point in time when a vulnerability was introduced is particularly cumbersome. In this paper, we provide an automatic approach for accurately estimating how long vulnerabilities remain in the code (their lifetimes). Our method relies on the observation that while it is difficult to pinpoint the exact point of introduction for one vulnerability, it is possible to accurately estimate the average lifetime of a large enough sample of vulnerabilities, via a heuristic approach. With our approach, we perform the first large-scale measurement of Free and Open Source Software vulnerability lifetimes, going beyond approaches estimating lower bounds prevalent in previous research. We find that the average lifetime of a vulnerability is around 4 years, varying significantly between projects (similar to 2 years for Chromium, similar to 7 years for OpenSSL). The distribution of lifetimes can be approximately described by an exponential distribution. There are no statistically significant differences between the lifetimes of different vulnerability types when considering specific projects. Vulnerabilities are getting older, as the average lifetime of fixed vulnerabilities in a given year increases over time, influenced by the overall increase of code age. However, they live less than non-vulnerable code, with an increasing spread over time for some projects, suggesting a notion of maturity that can be considered an indicator of quality. While the introduction of fuzzers does not significantly reduce the lifetimes of memory-related vulnerabilities, further research is needed to better understand and quantify the impact of fuzzers and other tools on vulnerability lifetimes and on the security of codebases.",NA

As knowledge-based firms, COSS companies' success depends heavily on the interplay among intangible resources such as human capital, relational capital, structural capital, and software quality. To observe these relationships, we conducted a hypothesis-testing questionnaire-type survey involving 200 software development experts and professionals working at 60 multinational COSS companies. Accordingly, the study unearthed two different but conjoint ways (i.e., direct and indirect) in which intellectual capital impacts COSS company's success. On the one hand, relational capital one of the intellectual capital components directly affects COSS company's success. On the other hand, relational and structural capital indirectly affect COSS company success through human capital, which, in turn, is itself mediated by software quality in a sequential mediation model. Therefore, COSS companies may need to prioritize software quality as it is the most critical variable impacting the success of COSS companies.",10.1109/ACCESS.2022.3170058
+1697,InProceedings,How to characterize the health of an Open Source Software project? A snowball literature review of an emerging practice,"Motivation: Society's dependence on Open Source Software (OSS) and the communities that maintain the OSS is ever-growing. So are the potential risks of, e.g., vulnerabilities being introduced in projects not actively maintained. By assessing an OSS project's capability to stay viable and maintained over time without interruption or weakening, i.e., the OSS health, users can consider the risk implied by using the OSS as is, and if necessary, decide whether to help improve the health or choose another option. However, such assessment is complex as OSS health covers a wide range of subtopics, and existing support is limited. Aim: We aim to create an overview of characteristics that affect the health of an OSS project and enable the assessment thereof. Method: We conduct a snowball literature review based on a start set of 9 papers, and identify 146 relevant papers over two iterations of forward and backward snowballing. Health characteristics are elicited and coded using structured and axial coding into a framework structure. Results: The final framework consists of 107 health characteristics divided among 15 themes. Characteristics address the socio-technical spectrum of the community of actors maintaining the OSS project, the software and other deliverables being maintained, and the orchestration facilitating the maintenance. Characteristics are further divided based on the level of abstraction they address, i.e., the OSS project-level specifically, or the project's overarching ecosystem of related OSS projects. Conclusion: The framework provides an overview of the wide span of health characteristics that may need to be considered when evaluating OSS health and can serve as a foundation both for research and practice.",10.1145/3555051.3555067

For example, toxic code review comments may raise pushback from an author to complete suggested changes. A toxic communication with another person may hamper future communication and collaboration. Research also suggests that toxicity disproportionately impacts newcomers, women, and other participants from marginalized groups. Therefore, toxicity is a barrier to promote diversity, equity, and inclusion. Since the occurrence of toxic communications is not uncommon among FOSS communities and such communications may have serious repercussions, the primary objective of my proposed dissertation is to automatically identify and mitigate toxicity during developers' textual interactions.

Several vulnerability scanners to detect known-vulnerable dependencies appeared in the last decade, however, there exists no case study investigating the impact of development practices, e.g., forking, patching, re-bundling, on their performance. This paper studies (i) types of modifications that may affect vulnerable open-source dependencies and (ii) their impact on the performance of vulnerability scanners. Through an empirical study on 7,024 Java projects developed at SAP, we identified four types of modifications: re-compilation, re-bundling, metadata-removal and re-packaging. In particular, we found that more than 87 percent (56 percent, resp.) of the vulnerable Java classes considered occur in Maven Central in re-bundled (re-packaged, resp.) form. We assessed the impact of these modifications on the performance of the open-source vulnerability scanners OWASP Dependency-Check (OWASP) and Eclipse Steady, GitHub Security Alerts, and three commercial scanners. The results show that none of the scanners is able to handle all the types of modifications identified. Finally, we present Achilles, a novel test suite with 2,505 test cases that allow replicating the modifications on open-source dependencies.",10.1109/TSE.2021.3101739
+1706,Article,ImShot: An Open-Source Software for Probabilistic Identification of Proteins In Situ and Visualization of Proteomics Data,"Imaging mass spectrometry (IMS) has developed into a powerful tool allowing label-free detection of numerous biomolecules in situ. In contrast to shotgun proteomics, proteins/peptides can be detected directly from biological tissues and correlated to its morphology leading to a gain of crucial clinical information. However, direct identification of the detected molecules is currently challenging for MALDI-IMS, thereby compelling researchers to use complementary techniques and resource intensive experimental setups. Despite these strategies, sufficient information could not be extracted because of lack of an optimum data combination strategy/software. Here, we introduce a new open-source software ImShot that aims at identifying peptides obtained in MALDI-IMS. This is achieved by combining information from IMS and shotgun proteomics (LC-MS) measurements of serial sections of the same tissue. The software takes advantage of a two group comparison to determine the search space of IMS masses after deisotoping the corresponding spectra. Ambiguity in annotations of IMS peptides is eliminated by introduction of a novel scoring system that identifies the most likely parent protein of a detected peptide in the corresponding IMS dataset. Thanks to its modular structure, the software can also handle LC-MS data separately and display interactive enrichment plots and enriched Gene Ontology terms or cellular pathways. The software has been built as a desktop application with a conveniently designed graphic user interface to provide users with a seamless experience in data analysis.

The solver surpasses the capabilities of similar open-source projects by considering a wide range of physical effects, e.g. multiple phases, melting, solidification, evaporation, and laser beam heat sources with an arbitrary intensity distribution and thus makes it an appealing framework, especially for the simulation of the laser powder bed fusion (LPBF) process. Herein, all relevant details and derivation considering the Marangoni effect are provided and validated by means of a benchmark problem by comparing the obtained results with the available analytical solution, with the results obtained from a commercial CFD tool and with the results of other authors. The modified solver is additionally validated by comparing the results from LPBF simulations with experimental data. Furthermore, the influence of the surface tension modeling on the mushy region is investigated. The optimized implementation shows improvements of the simulation results in both the dimensions and shape of the melt pool and the resulting surface with regard to the experimental data.",10.1088/1361-651X/ac4a26

Widely shared reports indicate that gender differences may be specific to each region. However, how complete can these reports be with little to no research reflective of the Open Source Software (OSS) process and communities software is now commonly developed in? Our study presents a multi-region geographical analysis of gender inclusion on GitHub. This mixed-methods approach includes quantitatively investigating differences in gender inclusion in projects across geographic regions and investigate these trends over time using data from contributions to 21,456 project repositories. We also qualitatively understand the unique experiences of developers contributing to these projects through a survey that is strategically targeted to developers in various regions worldwide. Our findings indicate that gender diversity is low across all parts of the world, with no substantial difference across regions. However, there has been statistically significant improvement in diversity worldwide since 2014, with certain regions such as Africa improving at faster pace. We also find that most motivations and barriers to contributions (e.g., lack of resources to contribute and poor working environment) were shared across regions, however, some insightful differences, such as how to make projects more inclusive, did arise. From these findings, we derive and present implications for tools that can foster inclusion in open source software communities and empower contributions from everyone, everywhere.",10.1109/TSE.2021.3092813

Appropriate management tools in free software, in addition to reducing the necessary investments in software, enable the development of new functionalities and also provide for local technological development. An association is made between free software and social technology, due to their mutual characteristics, in which technology is developed and shared by the community, providing autonomy and independence. The objective is to raise knowledge and application of information technology governance using free tools. To achieve this goal, a literature review on IT governance and free software was carried out, with a focus on Gestionnaire Libre de Parc Informatique (GLPI). Then, a research with exploratory-descriptive objective, qualitative-quantitative approach, with field research procedures and case study was carried out. Data were obtained through the application of a questionnaire, being the case unit the Federal Institute of Sao Paulo. It was applied as analysis method: content analysis, comparative analysis and, finally, a descriptive analysis. As a result, it was observed that governance brings the proposal of transparency in the use of technologies, human resources and actions performed in society, by society and for society. It is concluded that the results achieved can contribute to expand the knowledge about the application of information technology governance practices and the use of free software in that institution and other related institutions, improvement in the services rendered to the population.",10.22279/navus.2022.v12.p01-17.1681

By identifying problems before they arise in production, it enhances the quality of the code. Finding the best reviewer for a code change, however, is extremely challenging especially in large scale, especially open source software stacks with cross functioning designs and collaborations among multiple developers and teams. Additionally, a review by someone who lacks knowledge and understanding of the code can result in high resource consumption and technical errors. The reviewers who have the specialty in both functioning (domain knowledge) and non-functioning areas of a commit are considered as the most qualified reviewer to look over any changes to the code. Quality attributes serve as the connection among the user requirements, delivered function description, software architecture and implementation through put the entire software stack cycle. In this study, we target on auto reviewer assignment in large scale software stacks and aim to build a self-learning, and self-correct platform for intelligently matching between a commit based on its quality attributes and the skills sets of reviewers. To achieve this, quality attributes are classified and abstracted from the commit messages and based on which, the commits are assigned to the reviewers with the capability in reviewing the target commits. We first designed machine learning schemes for abstracting quality attributes based on historical data from the OpenStack repository. Two models are built and trained for automating the classification of the commits based on their quality attributes using the manual labeling of commits and multi-class classifiers. We then positioned the reviewers based on their historical data and the quality attributes characteristics. Finally we selected the recommended reviewer based on the distance between a commit and candidate reviewers. In this paper, we demonstrate how the models can choose the best quality attributes and assign the code review to the most qualified reviewers. With a comparatively small training dataset, the models are able to achieve F-1 scores of 77\\% and 85.31\\%, respectively.",10.1145/3551349.3561147

Experiments are conducted to quantify selectivity of fishing gears and how variables such as gear design (e.g., mesh size, mesh shape), environmental parameters (e.g., light, turbidity, substrate) or biological parameters (e.g., fish condition) alter selectivity; the resulting data need to be analyzed using specialized statistical methods in many cases. Here, we present a new tool for analyzing this type of data: an R package named ``selfisher{''}. It allows estimating multiple fixed effects (e.g., fish length, total catch weight, environmental variables) and random effects (e.g, haul). A bootstrapping procedure is also provided. We demonstrate its use via four case studies, including (A) covered codend analyses of four gears, (B) a paired gear study with numerous covariates, (C) a catch comparison study of unpaired hauls of gillnets and (D) a catch comparison study of paired hauls using polynomials and splines.

Importantly, obtained data can be directly used for multiple applications in fields such as fundamental biology, toxicology, or medicine. Particle movement in biorelevant media can be readily monitored using microscopy and converted into time-resolved trajectories using freely available tracking software. However, translation into tangible and meaningful parameters is time consuming and not always intuitive. We developed new software-MPTHub-as an open-access, standalone, user-friendly tool for the rapid and reliable analysis of particle trajectories extracted from video microscopy. The software was programmed using Python and allowed to import and analyze trajectory data, as well as to export relevant data such as individual and ensemble time-averaged mean square displacements and effective diffusivity, and anomalous transport exponent. Data processing was reliable, fast (total processing time of less than 10 s), and required minimal memory resources (up to a maximum of around 150 MB in random access memory). Demonstration of software applicability was conducted by studying the transport of different polystyrene nanoparticles (100-200 nm) in mucus surrogates. Overall, MPTHub represents a freely available software tool that can be used even by inexperienced users for studying the transport of particles in biorelevant media.",10.3390/nano12111899

Thereby, the proposed models will be able to comprehend two characteristics of OSS and network environment. Then, it will be useful to assess the operation effort expenditures with network environment of edge OSS service.

Also, OSS projects will heavily depend the environment of internet network. This paper focuses on the irregular fluctuation of operation performance measures for OSS project management. We apply the double jump diffusion process models to the noisy cases in the operation of OSS. In particular, the maintenance effort is estimated by the stochastic differential equation model in terms of OSS project management. Moreover, we propose the method of maintenance effort management based on the double jump diffusion process model considering the irregular fluctuation of performance for OSS projects. Thereby, it will be helpful for the OSS developers and managers to understand the maintenance effort status of OSS from the standpoint of OSS project management.

+1719,Article,Mapping the Spatial Conditions of Polycentric Urban Development in Europe: An Open-source Software Tool,"Urban polycentricity has become a key concept in urban and regional studies and is increasingly adopted as an organizational framework for conducting empirical research. Within this literature, polycentric urban regions are commonly defined as territories that have multiple, proximately located (sub)centers and are characterized by balanced urban development. However, analytical-operational frameworks to identify and classify PURs are often ad hoc efforts to answer a specific research question and underlying work is often shelved rather than shared and/or made accessible. As a result, challenges associated with generalizability, reproducibility, and replicability clearly loom large in the urban polycentricity literature. Against this backdrop, this article describes the discrepancy between a rich debate on polycentricity and the paucity of tools enabling the disambiguation and reproducibility of results claimed by various authors around this polysemic concept. We present an online and open tool-PURban-that brings together the major analytical-operational frameworks and data sets in urban polycentricity research and allows parametrizing key operational choices. To illustrate the tool, we demonstrate how it facilitates the identification, mapping and analysis of degrees of morphological polycentricity in European urban systems. We conclude by reflecting on how this tool can act as a catalyst for future research on urban polycentricity.",10.1111/gean.12313

This inherent complexity, however, does not mean that the social world is chaotic, random, or unstructured. Rather, structural forms do emerge and co-exist in social settings. It is the emergence, maintenance, and decay of these structures that allows researchers to detect temporary stability and provides them with the means to make predictions about continuity and change in social dynamics. Arguably then, the main challenge in the study of the social world consist of developing robust and consistent strategies or tools capable of tracing, mapping, or retrieving these structural forms in order to ultimately model this social complexity. Accordingly, the overarching purpose of this study consists of addressing this analytic and methodological challenge by proposing a groundbreaking analytic framework, and its corresponding software application, designed to extract temporal and dynamic structures in the social world relying on complex realism, complex systems, dynamic temporal network analyses, and data science and visualization techniques. Together, these frameworks constitute the foundations of Mapping, Organizing, and Visualizing Interdependent Events (MOVIE), an analytic framework [and software application] designed to ease the understanding of, individually-produced or interactively-generated, events and knowledge evolution, by tracing and recreating the processes that may have affected participants' experiences, outcomes, and standpoints. To demonstrate MOVIE's performance and rigor in capturing and recreating the dynamic complexity of micro-level interactions, the analyses relied on publicly available data sources on foreign policy and conflict resolution. All data elements and tools are provided with this study to make these analyses fully transparent and reproducible. MOVIE can trace/recreate the temporal elements embedded in existing qualitative databases (e.g. those generated with NVivo/MAXQDA/Atlas.ti), even if they were created without considering their dynamic time-evolving features, whose meaning-building relevance may help inform policy planning and action.",10.1177/20597991221119012

Such an incorporation of COTS tools into an overall open-source approach completely annihilates the actual open-source advantages and goals. In this tool paper, we demonstrate how we eliminated a COTS tool from the otherwise open-source-based generation and evolution workflow of the domain-specific modeling language East-Adl, used in the automotive industry to describe a variety of interdisciplinary aspects of vehicle systems. By switching to a pure open-source solution, East-Adl becomes easier to inspect, evolve, and develop a community around.

The main idea of this contribution is to review from a practical point of view the open-source software environment that can be useful for the design process of a thermoelectric generator. Our environment consists of the software modules Salome Platform, Gmsh, and FEniCSx. The partial differential equations representing the thermoelectric phenomena are solved using the finite element method.

Due to its stability and robustness, Computational Fluid Dynamics (CFD) commercial software is generally utilized for analyzing complex systems; however, its licensing is expensive. Nowadays, open-source software is a viable substitute for proprietary software. This work presents a CFD analysis of the hydrodynamics of a finned tube using the OpenFOAM and SALOME Meca platforms. The results are compared with experimental data and CFD using the commercial software Fluent, both previously reported in the open literature. This work studies the fluid flow pattern around a tube with six 45-degree-angled fins, and the working fluid, air, is considered as an incompressible fluid. Special attention is paid to calculating the pressure coefficient distribution for the internal and external surfaces of the inclined fins. Open-source platforms allow researchers to visualize how the airflow interacts with the cylinder and the fin surfaces to form a fluid structure, formerly known as a horseshoe vortex system. The findings of the analysis of flow dynamics in the channel between inclined fins and in the wake help explain the results obtained in experimental tests and are relevant for the configuration of a bank of tubes with inclined fins.",10.3390/fluids7080282

Most organizations do not have access to sufficient and reliable forms of such data from past projects. As such, the existing SDEE methods suffer from low usage and accuracy. We propose an efficient SDEE method for open source software, which provides accurate and fast effort estimates. The significant contributions of our article are (i) novel SDEE software metrics derived from developer activity information of various software repositories, (ii) an SDEE dataset comprising the SDEE metrics' values derived from approximately 13,000 GitHub repositories from 150 different software categories, and (iii) an effort estimation tool based on SDEE metrics and a software description similarity model. Our software description similarity model is basically a machine learning model trained using the PVA on the software product descriptions of GitHub repositories. Given the software description of a newly envisioned software, our tool yields an effort estimate for developing it.

+1731,Article,On the Relationship Between the Developer's Perceptible Race and Ethnicity and the Evaluation of Contributions in OSS,"Context: Open Source Software (OSS) projects are typically the result of collective efforts performed by developers with different backgrounds. Although the quality of developers' contributions should be the only factor influencing the evaluation of the contributions to OSS projects, recent studies have shown that diversity issues are correlated with the acceptance or rejection of developers' contributions. Objective: This paper assists this emerging state-of-the-art body on diversity research with the first empirical study that analyzes how developers' perceptible race and ethnicity relates to the evaluation of the contributions in OSS. We also want to create awareness of the racial and ethnic diversity in OSS projects. Methodology: We performed a large-scale quantitative study of OSS projects in GitHub. We extracted the developers' perceptible race and ethnicity from their names in GitHub using the Name-Prism tool and applied regression modeling of contributions (i.e, pull requests) data from GHTorrent and GitHub. Results: We observed that (1) among the developers whose perceptible race and ethnicity was captured by the tool, only 16.56 percent were perceptible as Non-White developers; (2) contributions from perceptible White developers have about 6-10 percent higher odds of being accepted when compared to contributions from perceptible Non-White developers; and (3) submitters with perceptible non-white races and ethnicities are more likely to get their pull requests accepted when the integrator is estimated to be from their same race and ethnicity rather than when the integrator is estimated to be White. Conclusion: Our initial analysis shows a low number of Non-White developers participating in OSS. Furthermore, the results from our regression analysis lead us to believe that there may exist differences between the evaluation of the contributions from different perceptible races and ethnicities. Thus, our findings reinforce the need for further studies on racial and ethnic diversity in software engineering to foster healthier OSS communities.",10.1109/TSE.2021.3073773

These vulnerabilities are introduced by developers, some intentionally or negligently. In this paper, we work to quantify the relative risk that a given developer represents to a software project. We propose using empirical software engineering based analysis on the vast data made available by GitHub to create a Developer Risk Score (DRS) for prolific contributors on GitHub. The DRS can then be aggregated across a project as a derived vulnerability assessment, we call this the Computational Vulnerability Assessment Score (CVAS). The CVAS represents the correlation between the Developer Risk score across projects and vulnerabilities attributed to those projects. We believe this to be a contribution in trying to quantify risk introduced by specific developers across open source projects. Both of the risk scores, those for contributors and projects, are derived from an amalgamation of data, both from GitHub and outside GitHub. We seek to provide this risk metric as a force multiplier for the project maintainers that are responsible for reviewing code contributions.

Using the weighted heterogeneous information network embedding method, extract and use the rich structural and semantic information in the weighted heterogeneous open source information network to learn the node representation of developers and projects, and fuse the personalized nonlinear fusion function into the matrix decomposition model for open source project recommendation. Finally, this paper makes a large number of comparative experiments based on the real GitHub open data set, and compares it with other project recommendation methods to verify the effectiveness of our proposed open source project recommendation model.

+1737,Article,Open Source Software Sustainability: Combining Institutional Analysis and Socio-Technical Networks,"Sustainable Open Source Software (OSS) forms much of the fabric of our digital society, especially successful and sustainable ones. But many OSS projects do not become sustainable, resulting in abandonment and even risks for the world's digital infrastructure. Prior work has looked at the reasons for this mainly from two very different perspectives. In software engineering, the focus has been on understanding success and sustainability from the socio-technical perspective: the OSS programmers' day-to-day activities and the artifacts they create. In institutional analysis, on the other hand, emphasis has been on institutional designs (e.g., policies, rules, and norms) that structure project governance. Even though each is necessary for a comprehensive understanding of OSS projects, the connection and interaction between the two approaches have been barely explored.In this paper, we make the first effort toward understanding OSS project sustainability using a dual-view analysis, by combining institutional analysis with socio-technical systems analysis. In particular, we (i) use linguistic approaches to extract institutional rules and norms from OSS contributors' communications to represent the evolution of their governance systems, and (ii) construct socio-technical networks based on longitudinal collaboration records to represent each project's organizational structure. We combined the two methods and applied them to a dataset of developer digital traces from 253 nascent OSS projects within the Apache Software Foundation (ASF) incubator. We find that the socio-technical and institutional features relate to each other, and provide complimentary views into the progress of the ASF's OSS projects. Refining these combined analyses can help provide a more precise understanding of the synchronization between the evolution of institutional governance and organizational structure.",10.1145/3555129

Driving this growth is the wide-spread availability of libraries and frameworks that provide many functionalities. Developers are saving time and money incorporating this functionality into their applications resulting in faster more feature-rich releases. Despite the growing success and the advantages that open source software provides, there is a dark side. Due to its community construction and largely unregulated distribution, the majority of open source software contains bugs, vulnerabilities and other issues making it highly susceptible to exploits. The lack of oversight in general hinders the quality of this software resulting in a trickle down effect in the applications that use it. Additionally, developers who use open source tend to arbitrarily download the software into their build systems but rarely keep track of what they have downloaded resulting in an excessive amount of open source software in their applications and in their ecosystem. This paper discusses processes and practices that users of open source software can implement into their environments that can safely track and control the introduction and usage of open source software into their applications, and report on some preliminary results obtained in an industrial context.

+1743,Article,Open-source software product line extraction processes: the ArgoUML-SPL and Phaser cases,"Software Product Lines (SPLs) are rarely developed from scratch. Commonly, they emerge from one product when there is a need to create tailored variants, or from existing variants created in an ad-hoc way once their separated maintenance and evolution become challenging. Despite the vast literature about re-engineering systems into SPLs and related technical approaches, there is a lack of detailed analysis of the process itself and the effort involved. In this paper, we provide and analyze empirical data of the extraction processes of two open-source case studies, namely ArgoUML and Phaser. Both cases emerged from the transition of a monolithic system into an SPL. The analysis relies on information mined from the version control history of their respective source-code repositories and the discussion with developers that took part in the process. Unlike previous works that focused mostly on the structural results of the final SPL, the contribution of this study is an in-depth characterization of the processes. With this work, we aimed at providing a deeper understanding of the strategies for SPL extraction and their implications. Our results indicate that the source code changes can range from almost a fourth to over half of the total lines of code. Developers may or may not use branching strategies for feature extraction. Additionally, the problems faced during the extraction process may be due to lack of tool support, complexity on managing feature dependencies and issues with feature constraints. We made publicly available the datasets and the analysis scripts of both case studies to be used as a baseline for extractive SPL adoption research and practice.",10.1007/s10664-021-10104-3
+1744,Article,PING-Mapper: Open-Source Software for Automated Benthic Imaging and Mapping Using Recreation-Grade Sonar,"The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation-grade side-scan sonar systems are increasingly used to aid scientific inquiries in aquatic environments due to their relative low-cost, ease of operation, low-weight, and ease of mounting on a variety of vessels. However, existing procedures and software for post-processing these data are either limited, closed source, or fail on data from new sonar models, limiting the development of reproducible workflows. Here, we present PING-Mapper, an open-source and freely available side-scan sonar post-processing toolset for processing and mapping sonar recordings from popular Humminbird instruments. The modular software automatically: (a) decodes sonar recordings from any Humminbird system, (b) exports ping attributes from every sonar channel, (c) uses sonar sensor depth for water column removal, and (d) exports sonogram tiles and georectified mosaics. Sonar channels are processed in parallel for quick decoding and metadata extraction. Major processing wokflows, including georectification and image export, are optimized to scale with computing resources. The software has been extensively tested using data from several rivers of varying character and distribution of depths, but could also be used in estuarine and lacustrine environments. Usage of PING-Mapper is illustrated in three case studies focused on mapping large woody debris, bathymetric mapping, and visual interpretation and mapping of substrates for selected reaches of the Pearl and Pascagoula river systems in Mississippi. Plain Language Summary Side-scan sonar instruments provide a way to survey and visualize the bottom of rivers, lakes, or oceans. Since the early 2000s, companies catering predominantly to anglers have manufactured recreation-grade side-scan sonar systems to aid fishermen in locating fish and identifying potential hazards. Scientists seeking to understand and manage aquatic habitats used these systems to create grayscale images of water bottoms because they are inexpensive, easy to operate, and require minimal mounting equipment on the boat. Software has been created by companies to process these data, but the underlying processing workflow and computer code are not publicly available, making it difficult to reproduce and compare results across studies. Other publicly available approaches and software are either outdated, not maintained, or not free. That is why we made PING-Mapper, a freely available software developed in an increasingly popular programming language called Python. We designed the software to work on any computer to export the data sets quickly and efficiently. The scientific use of exported data sets is demonstrated with three case studies focused on locating and mapping targets (specifically large trees and branches), creating depth maps, and visually discerning the distributions of common substrates, such as sand and cobble.",10.1029/2022EA002469
+1745,Article,Precision Fertilizer and Irrigation Control System Using Open-Source Software and Loose Communication Architecture,"Agricultural fertilization and irrigation are closely related to the problems of agricultural yield, product quality, and environmental pollution. Precision fertilization and irrigation is an effective method to solve this problem. In order to precisely control plant fertilization and irrigation, a monitoring system is designed and implemented using open-source software, loose communication structure, industrial control computer (IPC), programmable logic controller (PLC), and control and monitoring devices. The control command management subsystem of the system's upper computer is built using GoWin IPC, cloud server, mobile devices, and 4G wireless network. Each application running in the upper computer is developed using open-source software such as PostgreSQL, Smobiler, etc. The fertilization and irrigation monitoring subsystem of the lower computer was built using HollySys PLC model LE5107L and different sensors for various data parameters as control units. The system allows real-time remote monitoring and control of agricultural precision fertilization and irrigation through mobile applications, with an average communication delay of 1.45 s between the upper and lower units, and less than 3 s overall, allowing for longterm stable communication. The current system can adapt to the variable environment in the field and has been operating stably in the field for 2 months. This paper provides a convenient system construction solution for field farmland where network wiring is not possible, and it has low construction and maintenance costs, reliable operation, and a flexible structure for agricultural applications.

Then, we discuss fault severity levels in order to consider the difficulty of fault correction. We use a deep feedforward neural network in order to estimate fault correction times. In particular, we consider the characteristics of fault trends by using three-dimensional graphs. Therefore, we can increase the recognizability of the proposed method based on deep learning for large-scale fault data from the standpoint of fault severity levels under edge OSS operation.",10.3390/math10091572
+1747,Article,"PsiNorm: A Fast, Efficient and Free Open-Source Software for Interpreting, Reporting and Archiving Neuropsychological Test Results","Objective: In many clinics, calculation and interpretation of neuropsychological test results, along with reporting, data organization and archiving of the data are done manually. In this era where most of the similar processes are automated, manual application may result in excessive time consumption, unnecessary use of qualified work-force, and is also open to error. A software that automates these processes for neuropsychological tests used for dementia assessment may overcome these issues. Methods: We aimed to develop a free, open source software not requiring specialized training, which would optimise the calculation, preparation of personal reports and archiving processes of neuropsychological tests, hence would easily be incorporated in to the daily work of psychologists. We've used Python 3.6 as the programming language, and JSON was used as the data interchange format to allow for personal alterations in the content. The tests were selected among those which are in common use for neuropsychological evaluation of adults in Turkey, with available norm values. (Funding: TUBITAK 214S048). Results: PsiNorm was developed, comprising widely used standardized tests for cognitive evaluation of adults in Turkey. The software is lightweight, compatible with most common operating systems, and easy-to-use. We've shown that Psinorm significantly reduced the time required for calculation of percentiles and norms as well as for producing a draft report. The reports are prepared in.txt format and the databases are prepared in MS Excel ve CSV formats. PsiNorm is available freely at psinorm.org. Conclusion: PsiNorm is a free, open-source software which is available for researchers and clinicians who perform neuropsychological tests. PsiNorm provides significant time and labor-force benefits, is easy-to-use and can be customized by the user.",10.5080/u26267

In this article, we introduce PyThea to the scientific community and provide an overview of the main functionality of the core software package and the web application. This package has been fully built in Python, with extensive use of libraries available within this language ecosystem. PyThea package provides a web application that can be used to reconstruct CMEs and shock waves. The application automatically retrieves and processes remote-sensing observations, and visualizes the imaging data that can be used for the analysis. Thanks to PyThea, the three-dimensional reconstruction of CMEs and shock waves is an easy task, with final products ready for publication. The package provides three widely used geometrical models for the reconstruction of CMEs and shocks, namely, the graduated cylindrical shell (GCS) and an ellipsoid/spheroid model. It also provides tools to process the final fittings and calculate the kinematics. The final fitting products can also be exported and reused at any time. The source code of PyThea package can be found in GitHub and Zenodo under the GNU General Public License v3.0.

+1749,Article,Qiber3D-an open-source software package for the quantitative analysis of networks from 3D image stacks,"Background Optical slice microscopy is commonly used to observe cellular morphology in 3D tissue culture, e.g., the formation of cell-derived networks. The morphometric quantification of these networks is essential to study the cellular phenotype. Commonly, the quantitative measurements are performed on 2D projections of the image stack, resulting in the loss of information in the third dimension. Currently available 3D image analysis tools rely on manual interactions with the software and are therefore not feasible for large datasets. Findings Here we present Qiber3D, an open-source image processing toolkit. The software package includes the essential image analysis procedures required for image processing, from the raw image to the quantified data. Optional pre-processing steps can be switched on/off depending on the input data to allow for analyzing networks from a variety of sources. Two reconstruction algorithms are offered to meet the requirements for a wide range of network types. Furthermore, Qiber3D's rendering capabilities enable the user to inspect each step of the image analysis process interactively to ensure the creation of an optimal workflow for each application. Conclusions Qiber3D is implemented as a Python package, and its source code is freely available at https://github.com/theia-dev/Qiber3D. The toolkit was designed using a building block principle to enable the analysis of a variety of structures, such as vascular networks, neuronal structures, or scaffolds from numerous input formats. While Qiber3D can be used interactively in the Python console, it is aimed at unsupervised automation to process large image datasets efficiently.",10.1093/gigascience/giab091
+1750,InProceedings,Recommending Good First Issues in GitHub OSS Projects,"Attracting and retaining newcomers is vital for the sustainability of an open-source software project. However, it is difficult for newcomers to locate suitable development tasks, while existing ``Good First Issues{''} (GFI) in GitHub are often insufficient and inappropriate. In this paper, we propose RecGFI, an effective practical approach for the recommendation of good first issues to newcomers, which can be used to relieve maintainers' burden and help newcomers onboard. RecGFI models an issue with features from multiple dimensions (content, background, and dynamics) and uses an XGBoost classifier to generate its probability of being a GFI. To evaluate RecGFI, we collect 53,510 resolved issues among 100 GitHub projects and carefully restore their historical states to build ground truth datasets. Our evaluation shows that RecGFI can achieve up to 0.853 AUC in the ground truth dataset and outperforms alternative models. Our interpretable analysis of the trained model further reveals interesting observations about GFI characteristics. Finally, we report latest issues (without GFI-signaling labels but recommended as GFI by our approach) to project maintainers among which 16 are confirmed as real GFIs and five have been resolved by a newcomer.",10.1145/3510003.3510196
+1752,Article,"Redundancy, Context, and Preference: An Empirical Study of Duplicate Pull Requests in OSS Projects","OSS projects are being developed by globally distributed contributors, who often collaborate through the pull-based model today. While this model lowers the barrier to entry for OSS developers by synthesizing, automating and optimizing the contribution process, coordination among an increasing number of contributors remains as a challenge due to the asynchronous and self-organized nature of distributed development. In particular, duplicate contributions, where multiple different contributors unintentionally submit duplicate pull requests to achieve the same goal, are an elusive problem that may waste effort in automated testing, code review and software maintenance. While the issue of duplicate pull requests has been highlighted, to what extent duplicate pull requests affect the development in OSS communities has not been well investigated. In this paper, we conduct a mixed-approach study to bridge this gap. Based on a comprehensive dataset constructed from 26 popular GitHub projects, we obtain the following findings: (a) Duplicate pull requests result in redundant human and computing resources, exerting a significant impact on the contribution and evaluation process. (b) Contributors' inappropriate working patterns and the drawbacks of their collaborating environment might result in duplicate pull requests. (c) Compared to non-duplicate pull requests, duplicate pull requests have significantly different features, e.g., being submitted by inexperienced contributors, being fixing bugs, touching cold files, and solving tracked issues. (d) Integrators choosing between duplicate pull requests prefer to accept those with early submission time, accurate and high-quality implementation, broad coverage, test code, high maturity, deep discussion, and active response. Finally, actionable suggestions and implications are proposed for OSS practitioners.",10.1109/TSE.2020.3018726

Herein, we report an open-source software for students and instructors to on-demand simulate optical reflection behaviors of one-dimensional photonic crystals (1D-PCs), a model system for understanding light-matter interactions relevant to materials science and optical physics. Specifically, our MATLAB application, ReflectSim, employs an adapted transfer matrix method simulation and can account for the effects of several critical material design parameters, including interfacial roughness and layer geometry, to determine the reflectance spectrum of user-defined 1D-PCs. By packing our codes into a graphical user interface, this software is simple to use and bypass the requirement of any coding experiences from users, which can be widely used as an education tool in high school/undergraduate classrooms and K-12 outreach activities.

+1755,Article,Reliability model of open source software considering fault introduction with generalized inflection S-shaped distribution,"Recently, the open source software (OSS) reliability has become one of hot issues. Owing to the uncertainty and complexity of OSS development, testing and debugging environments, OSS are completed dynamically. When detected faults are removed for OSS, they are likely to introduce new faults. Moreover, under the different OSS debugging environments, fault introduction will show different changes. For example, the fault introduction rate shows a decrease change, or increasing first and then decreasing change over time. Considering the complex and dynamic changes in fault introduction, an OSS reliability model that fault introduction obeys a generalized inflection S-shaped distribution is proposed in this paper. Experimental results indicate that the fitting and predictive performance of the proposed model is good. The established model in this paper can adapt the dynamical and complicated changes of fault introduction during OSS debugging. Moreover, the established model can accurately forecast the number of remaining faults in OSS, and assist developers to evaluate the actual OSS reliability.",10.1007/s42452-022-05125-6
+1756,Article,Robotic observation pipeline for small bodies in the solar system based on open-source software and commercially available telescope hardware,"The observation of small bodies in the Space Environment is an ongoing important task in astronomy. While nowadays new objects are mostly detected in larger sky surveys, several follow-up observations are usually needed for each object to improve the accuracy of orbit determination. In particular objects orbiting close to Earth, so called Near-Earth Objects (NEOs) are of special concern as a small but not negligible fraction of them can have a non-zero impact probability with Earth. Additionally, the observation of manmade space debris and tracking of satellites falls in the same class measurements. Telescopes for these follow-up observations are mainly in a aperture class between 1 m down to approximately 25 cm. These telescopes are often hosted by amateur observatories or dedicated companies like 6ROADS specialized on this type of observation. With upcoming new NEO search campaigns by very wide field of view telescopes, like the Vera C. Rubin Observatory, NASA's NEO surveyor space mission and ESA's Flyeye telescopes, the number of NEO discoveries will increase dramatically. This will require an increasing number of useful telescopes for follow-up observations at different geographical locations. While well-equipped amateur astronomers often host instruments which might be capable of creating useful measurements, both observation planning and scheduling, and also analysis are still a major challenge for many observers. In this work we present a fully robotic planning, scheduling and observation pipeline that extends the widely used open-source cross-platform software KStars/Ekos for Instrument Neutral Distributed Interface (INDI) devices. The method consists of algorithms which automatically select NEO candidates with priority according to ESA's Near-Earth Object Coordination Centre (NEOCC). It then analyses detectable objects (based on limiting magnitudes, geographical position, and time) with preliminary ephemeris from the Minor Planet Center (MPC). Optimal observing slots during the night are calculated and scheduled. Immediately before the measurement the accurate position of the minor body is recalculated and finally the images are taken. Besides the detailed description of all components, we will show a complete robotic hard- and software solution based on our methods.",10.3389/fspas.2022.895732
+1757,Article,SRBF\\_Soft: a Python-based open-source software for regional gravity field modeling using spherical radial basis functions based on the data-adaptive network design methodology,"This study introduces a novel open-source Python software package called SRBF\\_Soft for the high-resolution regional gravity field determination using various spherical radial basis functions (SBRFs) in terms of point mass, Poisson, and Poisson wavelet kernel. The modeling approach considers residual gravity field functionals generated by the well-known remove-compute-restore (RCR) technique where the long and short wavelength parts of the gravity signal are provided by a global geopotential model (GGM) and digital terrain model (DTM), respectively. A new data-adaptive network design methodology called k-SRBF is used to construct a network of SRBFs. The appropriate bandwidths (depths) are chosen using the generalized cross-validation (GCV) technique. The unknown SRBFs coefficients are estimated by applying the least-squares method where the extended Gauss Markov Model (GMM) with additional prior information is applied if the normal equation matrix is ill-conditioned. In such a case, the optimal regularization parameter is determined by variance component estimation (VCE). By utilizing parallel processing in every stage of the RCR technique, including creating the design matrix, the computational time is remarkably decreased relative to the number of processors used in the modeling. The performance of the software has been tested and validated in the Auvergne test area (France) on the basis of real terrestrial gravity data. The differences between estimated and observed height anomaly points (GNSS/leveling) amount to about 3 cm in terms of standard deviation (STD) for all kernels indicating that the SRBF\\_Soft possesses the capability to be applied in regional gravity field modeling as an efficient and reliable software.",10.1007/s12145-022-00790-y

We retrospectively collected data on advanced NSCLC not receiving a first-line platinum combination, focusing on clinical selection criteria. Up to 30\\% of newly diagnosed advanced EGFR/ALK negative and PD-L1 < 50\\% NSCLC patients do not receive a first-line platinum doublet. Main clinical selection criteria were older age (>70 years), comorbidities and poor performance status. A single agent chemotherapy was offered with the prevalence of oral metronomic vinorelbine. In the whole population, progression-free survival and overall survival ranged from 4.5 to 5 months and from 9 to 10.5 months, respectively. Limited evidence is available concerning the selection criteria and the outcomes of platinum unfit newly diagnosed advanced NSCLC patients receiving single-agent chemotherapy. We retrospectively collected data on consecutive, stage IIIB-IV, EGFR/ALK negative and PD-L1 < 50\\% NSCLC patients treated with first-line single agent chemotherapy. Baseline characteristics, outcome measures and toxicities were recorded, as well as criteria according to which treatment selection was made and what percentage of patients did not receive a first-line platinum-based chemotherapy. Two-hundred and twenty-one patients were included.

However, it is time-consuming because of the bioinformatics processes involved, including sequence trimming, consensus sequence generation, and public database searches. We developed a simple and fully automated software that enabled species-level identification of NTM from trace files, SnackNTM (https://github.com/Young-gonKim/SnackNTM). Methods: JAVA programing language was used for software development. The SnackNTM diagnostic algorithm utilized 16S rRNA gene sequences, according to the Clinical \\& Laboratory Standards Institute guidelines, and an rpoB gene region was adjunctively utilized to narrow down the species. The software performance was validated using trace files of 234 clinical cases, comprising 217 consecutive cases and 17 additionally selected cases of unique species. Results: SnackNTM could analyze multiple cases at once, and all the bioinformatics processes required for sequence-based NTM identification were automatically performed with a single mouse click. SnackNTM successfully identified 95.9\\% (208/217) of consecutive clinical cases, and the results showed 99.0\\% (206/208) agreement with manual classification results. SnackNTM successfully identified all 17 cases of unique species. In a processing time comparison test, the analysis and reporting of 30 cases, which took 150 minutes manually, took only 40 minutes with SnackNTM. Conclusions: SnackNTM is expected to reduce the workload for NTM identification, especially in clinical laboratories that process large numbers of cases.",10.3343/alm.2022.42.2.213

+1768,Article,Software reliability model of open source software based on the decreasing trend of fault introduction,"Open source software (OSS) has become one of the modern software development methods. OSS is mainly developed by developers, volunteers, and users all over the world, but its reliability has been widely questioned. When OSS faults are detected, volunteers or users send them to developers by email or network. After the developer confirms the fault, it will be randomly assigned to the debugger who may be a developer, a volunteer, or a user. These open source community contributors also have the phenomenon of learning when removing faults. When the detected faults are removed, the number of introduced faults decreases gradually. Therefore, this study proposes a software reliability model with the decreasing trend of fault introduction in the process of OSS development and testing. The validity of the proposed model and the accuracy of estimating residual faults are verified by experiments. The proposed model can be used to evaluate the reliability and predict the remaining faults in the actual OSS development and testing process.",10.1371/journal.pone.0267171

Therefore, the use of biomaterials/scaffolds for maxillofacial bone regrowth has been attracting great interest from many surgical specialties and experts. Many approaches have been devised in order to create an optimal bone scaffold capable of achieving desirable degrees of bone integration and osteogenesis. Osteogenesis represents a complex physiological process involving multiple cooperating systems. A tight relationship between the immune and skeletal systems has lately been established using the concept of ``osteoimmunology,{''} since various molecules, particularly those regulating immunological and inflammatory processes, are shared. Inflammatory mediators are now being implicated in bone remodeling, according to new scientific data. In this study, a profiler PCR array was employed to evaluate the expression of cytokines and chemokines in human adipose derived-mesenchymal stem cells (hASCs) cultured on porous hydroxylapatite (HA)/Collagen derived Bio-Oss((R))/Avitene scaffolds, up to day 21. In hASCs grown on the Bio-Oss((R))/Avitene biomaterial, 12 differentially expressed genes (DEGs) were found to be up-regulated, together with 12 DEG down-regulated. Chemokine CCL2, which affects bone metabolism, tested down-regulated. Interestingly, the Bio-Oss((R))/Avitene induced the down-regulation of pro-inflammatory inter-leukin IL-6. In conclusion, our investigation carried out on the Bio-Oss((R))/Avitene scaffold indicates that it could be successfully employed in maxillofacial surgery.

However, research on the structural stability of the evolving developer collaboration network in OSS communities is relatively insufficient. In this paper, according to the software version sequence, we construct the corresponding developer collaboration network of the Angular OSS community and then analyse this network's structural stability during network evolution. The results show that the network always presents an economical modular small-world structure during its evolution. The maintenance of the structure is related to a cohesive core, which is composed of two types of nodes (i.e., hubs and connectors). The hubs organize noncore nodes to form modules, while connectors facilitate the formation of inter-module connections.

This trend, as well as technological advancements in the unmanned aerial vehicle (UAV) industry, have opened blue skies for both researchers and surveyors. In this study, we aimed to assess the quality of the sparse point cloud obtained with a consumer UAV and a FOSS. To achieve this goal, we also process the same image dataset with a commercial software package using its results as a term of comparison. Various analyses were conducted, such as the image residuals analysis, the statistical analysis of GCPs and CPs errors, the relative accuracy assessment, and the Cloud-to-Cloud distance comparison. A support survey was conducted to measure 16 markers identified on the object. In particular, 12 of these were used as ground control points to scale the 3D model, while the remaining 4 were used as check points to assess the quality of the scaling procedure by examining the residuals. Results indicate that the sparse clouds obtained are comparable. MicMac (R) has mean image residuals equal to 0.770 pixels while for Metashape (R) is 0.735 pixels. In addition, the 3D errors on control points are similar: the mean 3D error for MicMac (R) is equal to 0.037 m with a standard deviation of 0.017 m, whereas for Metashape (R), it is 0.031 m with a standard deviation equal to 0.015 m.

Both a qualitative study and a quantitative study are conducted, and data analysis confirms both the Trust -> CCBs and the CCBs -> Trust hypotheses along the time dimension, revealing CCBs-Trust interactions as a mechanism for maintaining sustained community participation. Further, while it is found that CCBs have an accumulative overall positive impact on trust, alternating positive and negative impacts of CCBs on trust over time are identified. In addition, a delayed impact is also identified in the Trust -> CCBs relationship.

This paper analyzes the governance of these organizations from the perspective of their structure and control, considering the development trajectory of three communitybased free software projects in Brazil. Results show that the constant need to produce modern technologies gives rise to external pressures that promote change - albeit temporary - in the governance of these projects, making them resemble a cathedral more than a bazaar. Governance does not follow a cycle of sequential improvement; it changes depending on the external organizational actors present, such as sponsors. This suggests the need for strategic and flexible governance to deal with the acquisition and allocation of organizational resources. Governance of the projects described here varies along a spectrum of (in)formality that allows both production models - cathedral or bazaar - to exist in the same organization at different periods.",10.1590/S0034-759020220104

In recent years, dose-surface maps (DSMs) have become increasingly popular for characterization of spatial dose distributions and identification of radiosensitive subregions for hollow organs. However, methodological variations and lack of open-source, publicly offered code-sharing between research groups have limited reproducibility and wider adoption. Purpose This paper presents rtdsm, an open-source software for DSM calculation with the intent to improve the reproducibility of and the access to DSM-based research in medical physics and radiation oncology. Methods A literature review was conducted to identify essential functionalities and prevailing calculation approaches to guide development. The described software has been designed to calculate DSMs from DICOM data with a high degree of user customizability and to facilitate DSM feature analysis. Core functionalities include DSM calculation, equivalent dose conversions, common DSM feature extraction, and simple DSM accumulation. Results A number of use cases were used to qualitatively and quantitatively demonstrate the use and usefulness of rtdsm. Specifically, two DSM slicing methods, planar and noncoplanar, were implemented and tested, and the effects of method choice on output DSMs were demonstrated. An example comparison of DSMs from two different treatments was used to highlight the use cases of various built-in analysis functions for equivalent dose conversion and DSM feature extraction. Conclusions We developed and implemented rtdsm as a standalone software that provides all essential functionalities required to perform a DSM-based study. It has been made freely accessible under an open-source license on Github to encourage collaboration and community use.",10.1002/mp.15900
+1779,Article,Technical Note: Open-Source Software for Water-Level Measurement in Images With a Calibration Target,"Image-based water level measurements offer data quality assurance through visual verification that no other method can provide. GaugeCam Remote Image Manager-Educational 2 (GRIME2) is a mature, open-source commercial friendly software application that automatically detects and measures water level in laboratory and field settings. The software relies on a dedicated target background for water line detection and image calibration. The system detects the change in pixel gray scale values associated with the intersection of the water level at the target surface. Fiducials on the target background are used to precisely create a pixel to real world coordinate transfer matrix and to correct for camera movement. The presented software package implements the algorithms and automates the water level measurement process, annotation of images with result overlays, creation of animations, and output of results to files that can be further analyzed in a spreadsheet or with R or Python. These GRIME2 features are illustrated using imagery from a coastal marsh field site. Tradeoffs between workflow and algorithm complexity and ease of use are discussed and future improvements are identified with the intention that this Findable, Accessible, Interoperable, and Reusable-inspired software can be adopted, modified and improved by the user community. While image resolution, quality and other factors associated with field deployment (e.g., water surface roughness, sun glare, shadows, and bio-fouling) will have an impact on measurement quality, previous controlled laboratory testing that did not manifest these issues showed potential for accuracy of +/- 3 mm (Gilmore et al., 2013, ).",10.1029/2022WR033203

Funding OSS development requires intentional focus on issues of scholarly credit, unique forms of labor, maintenance, governance, and inclusive community-building. Such issues cut across different scientific disciplines that make them of interest to a variety of funders and institutions but may present challenges in understanding generalized needs. Here we present 10 simple rules for investing in scientific OSS and the teams who build and maintain it. Author summary As funders of scientific research, we have a unique knowledge of the challenges that researchers face in finding support for the many parts of their projects. Scientific software is a central part of the research process and is increasingly in need of investments to ensure continued advancement and progress. Here we draw on our experiences as funders to provide guidance and considerations for funders and other community members interested in supporting scientific software. We address specific issues related to software, including contributor community development, governance, sustainability, and diversity and inclusion.",10.1371/journal.pcbi.1010627
+1783,InProceedings,The Influence of Sponsorship on Open-Source Software Developers' Activities on GitHub,"Studies on the OSS communities have shown that financial supports are critical to OSS developers and projects to maintain their progress and sustainability. However, there were few developers being paid directly for maintaining OSS projects in the past. The GitHub Sponsors program that brings financial supports to the general OSS developers in GitHub-the world's largest OSS platform may make a difference on this situation in the future. In this paper, we present a data set on GitHub Sponsors and conduct a data-driven study to analyze the participants of the program and the impact of sponsorships to developers' activities and their projects' outcomes and qualities. The results of our survey suggest that most developers state they will contribute more with sponsorships and provide some privilege for their sponsors. And through quantitative study, we find that developers make more contributions on GitHub after they got/offered sponsorships. Moreover, gaining sponsorship also has a weakly positive impact on developers' collaborators that did not get sponsorship. And not only developers, but their own or contributed projects also can be motivate by sponsorships. Our findings are useful to the community by understanding the impact of sponsorships on users' activities and projects' progress and sustainability, and helping the managers to improve the current financial support mechanism.",10.1109/COMPSAC54236.2022.00144

The purpose of this paper is to analyse the teachers' motivation to contribute to OSS projects for teaching. A structural equation model (SEM) has been defined under the postulates of the Path-Goal leadership theory and Motivational Behaviour. This model has tried to explain and predict the use of OSS solutions by teachers in an educational context. The findings confirm the positive relationships between transactional and transformational leaderships with extrinsic and intrinsic motivations. Additionally, the findings show the positive relationship between extrinsic and intrinsic motivations and the contributions to the OSS project in teaching. This research suggests several implications for both leaders and members of an OSS project in an educational context. First, the contribution of teachers and instructors to the project is greater when the motivation is fostered by the leader. Second, this study finds that motivating the participants of a project - teachers in this case - is highly recommended, in order to reach a successful adoption of OSS solutions for education.",10.1080/09537325.2021.1963698

Pangandaran Regency, after divided from Ciamis Regency, requires attention from higher education stakeholders in the spatial field to manage its natural and social-economic resources. Free and Open-Source Software-Geographic Information System (FOSS-GIS) training is the appropriate solution through the community service and empowerment program from university. This study aims to determine the effect of FOSS-GIS training on spatial habits, spatial knowledge, and spatial skills. The online training was attended by 24 participants who are officials from the government of Pangandaran Regency. To determine the effect, we used Wilcoxon's Test and Paired Sample T-Test on spatial habits and spatial knowledge. We analyzed the spatial skills of self-paced tasks and presentation of results by the participants. This study shows a positive effect of FOSS-GIS training which can be seen from the increase in scores between pre-test and post-test. The spatial habits increased 5.4 percent, whereas the spatial knowledge increased 6.1 percent. Participants were also able to demonstrate all their spatial skills to make a tsunami hazard map and present it.

+1793,Article,The interplay between volunteers and firm's employees in distributed innovation: emergent architectures and stigmergy in open source software,"This paper focuses on the interplay between firms and open and collaborative innovation communities. We develop a formal model where both volunteers (agents setting their agendas freely) and firm's employees (agents whose agenda is mostly set by their employer) participate in the creation of a common artifact. In this framework, we discuss how firms can influence the architecture of the emerging product to assure fast and performant development and a desirable distribution of innovative labor within the project team. We find that closing the project only to employees implies high speed and performance if employees are given autonomy in certain dimensions and are directed in others. In this case, however, we observe a trade-off in terms of ideal core-periphery division of labor on one side and development speed and performance on the other side. At the opposite extreme, creating a volunteer-only project can ease the trade-off but assures positive results only if the firm is able to set up an entry mechanism that ``surgically{''} selects volunteers with specific preferences. A mixture of both employees and volunteers can strike a good balance, relaxing the two constraints.",10.1093/icc/dtac037

Still, all contributors may find it difficult to assimilate into the OSS community even they are enthusiastic to make contributions. We thus suggest that partner recommendation across different roles may benefit both the users and developers, i.e., once we are able to make successful recommendation for those in need, it may dramatically contribute to the productivity of developers and the enthusiasm of users, thus further boosting OSS projects' development. Motivated by this potential, we model the partner recommendation as link prediction task from email data via network embedding methods. In this article, we introduce time-series snapshot network (TSSN) that is a mixture network to model the interactions among users and developers. Based on the established TSSN, we perform temporal biased walk (TBW) to automatically capture both temporal and structural information of the email network, i.e., the behavioral similarity between individuals in the OSS email network. Experiments on ten Apache data sets demonstrate that the proposed TBW significantly outperforms a number of advanced random walk-based embedding methods, leading to the state-of-the-art recommendation performance.",10.1109/TCSS.2021.3070914

Materials and Methods: Sixty-eight patients who had difficulty in cannulation into the papilla located at the lower, left, or right side of the periampullary diverticulum upon endoscopic retrograde cholangiopancreatography (ERCP) were recruited at Taizhou Hospital from July 2016 to June 2020. A random number table was used to divide the patients into an intervention (with titanium clip-dental floss traction) group and a control group (n=34 in each group). Patients in both groups underwent ERCP. The cannulation time, cannulation success rate, incidence of postprocedural complications after ERCP, hospitalization time, and hospitalization expenses in the 2 groups were compared. Result: The cannulation time was 15.3 +/- 4.1 minutes in the intervention group, which was less than that in the control group (25.7 +/- 6.5 min). The cannulation success rate was 77 +/- 12.1\\% in the intervention group, which was higher than that in the control group (43 +/- 16.7\\%). Postprocedural complications occurred in 2 patients in the intervention group and 6 patients in the control group, with no significant differences.

During their service life, they are subject to deterioration which may reduce their safety and functionality. The detection of bridge damage is necessary for proper maintenance activities. To date, assessing the health status of the bridge and all its elements is carried out by identifying a series of data obtained from visual inspections, which allows the mapping of the deterioration situation of the work and its conservation status. There are, however, situations where visual inspection may be difficult or impossible, especially in critical areas of bridges, such as the ceiling and corners. In this contribution, the authors acquire images using a prototype drone with a low-cost camera mounted upward over the body of the drone. The proposed solution was tested on a bridge in the city of Turin (Italy). The captured data was processed via photogrammetric process using the opensource Micmac solution. Subsequently, a procedure was developed with FOSS tools for the segmentation of the orthophoto of the intrados of the bridge and the automatic classification of some defects found on the analyzed structure.

For example, maintainers help lead the project and promote its longevity, technical writers assist with documentation, bug reporters identify defects in software, and developers program the software. However, it is unknown which skills are used in OSS development as well as OSS contributors' general attitudes towards skills in OSS. In this paper, we address this gap by administering a survey to a diverse set of 455 OSS contributors. Guided by these responses as well as prior literature on software development expertise and social factors of OSS, we develop a model of skills in OSS that considers the many contexts OSS contributors work in. This model has 45 skills in the following 9 categories: technical skills, working styles, problem solving, contribution types, project-specific skills, interpersonal skills, external relations, management, and characteristics. Through a mix of qualitative and quantitative analyses, we find that OSS contributors are actively motivated to improve skills and perceive many benefits in sharing their skills with others. We then use this analysis to derive a set of design implications and best practices for those who incorporate skills into OSS tools and platforms, such as GitHub.",10.1145/3540250.3549082

+1808,InProceedings,Understanding the Practice of Security Patch Management across Multiple Branches in OSS Projects,"Since the users of open source software (OSS) projects may not use the latest version all the time, OSS development teams often support code maintenance for old versions through maintaining multiple stable branches. Typically, the developers create a stable branch for each old stable version, deploy security patches on the branch, and release fixed versions at regular intervals. As such, old-version applications in production environments are protected from the disclosed vulnerabilities in a long time. However, the rapidly growing number of OSS vulnerabilities has greatly strained this patch deployment model, and a critical need has arisen for the security community to understand the practice of security patch management across stable branches. In this work, we conduct a large-scale empirical study of stable branches in OSS projects and the security patches deployed on them via investigating 608 stable branches belonging to 26 popular OSS projects as well as more than 2,000 security fixes for 806 CVEs deployed on stable branches. Our study distills several important findings: (i) more than 80\\% affected CVE-Branch pairs are unpatched; (ii) the unpatched vulnerabilities could pose a serious security risk to applications in use, with 47.39\\% of them achieving a CVSS score over 7 (High or Critical Severity); and (iii) the patch porting process requires great manual efforts and takes an average of 40.46 days, significantly extending the time window for N-day vulnerability attacks. Our results reveal the worrying state of security patch management across stable branches. We hope our study can shed some light on improving the practice of patch management in OSS projects.",10.1145/3485447.3512236

However, most urban indicator frameworks use coarse spatial scales that either only allow between-city comparisons, or require expensive, technical, local spatial analyses for within-city comparisons. This study developed a reusable, open-source urban indicator computational framework using open data to enable consistent local and global comparative analyses. We show this framework by calculating spatial indicators-for 25 diverse cities in 19 countries-of urban design and transport features that support health and sustainability. We link these indicators to cities' policy contexts, and identify populations living above and below critical thresholds for physical activity through walking. Efforts to broaden participation in crowdsourcing data and to calculate globally consistent indicators are essential for planning evidence-informed urban interventions, monitoring policy effects, and learning lessons from peer cities to achieve health, equity, and sustainability goals.",10.1016/S2214-109X(22)00072-9
+1811,Article,Visualization and Quantification of the Unrepaired Complete Atrioventricular Canal Valve Using Open-Source Software,"Background: Repair of complete atrioventricular canal (CAVC) is often complicated by residual left atrioven-tricular valve regurgitation. The structure of the mitral and tricuspid valves in biventricular hearts has previously been shown to be associated with valve dysfunction. However, the three-dimensional (3D) structure of the entire unrepaired CAVC valve has not been quantified. Understanding the 3D structure of the CAVC may inform optimized repair.Methods: Novel open-source work flows were created in SlicerHeart for the modeling and quantification of CAVC valves on the basis of 3D echocardiographic images. These methods were applied to model the annulus, leaflets, and papillary muscle (PM) structure of 35 patients (29 with trisomy 21) with CAVC using trans -thoracic 3D echocardiography. The mean leaflet and annular shapes were calculated and visualized using shape analysis. Metrics of the complete native CAVC valve structure were compared with those of normal mitral valves using the Mann-Whitney U test. Associations between CAVC structure and atrioventricular valve regurgitation were analyzed.Results: CAVC leaflet metrics varied throughout systole. Compared with normal mitral valves, the left CAVC PMs were more acutely angled in relation to the annular plane (P < .001). In addition, the anterolateral PM was laterally and inferiorly rotated in CAVC, while the posteromedial PM was more superiorly and laterally rotated, relative to normal mitral valves (P < .001). Lower native CAVC atrioventricular valve annular height and annular height-to-valve width ratio before repair were both associated with moderate or greater left atrio-ventricular valve regurgitation after repair (P < .01).Conclusions: It is feasible to model and quantify 3D CAVC structure using 3D echocardiographic images. The results demonstrate significant variation in CAVC structure across the cohort and differences in annular, leaflet, and PM structure compared with the mitral valve. These tools may be used in future studies to catalyze future research intended to identify structural associations of valve dysfunction and to optimize repair in this vulnerable and complex population.

+1812,Article,Wayback Machine: A tool to capture the evolutionary behavior of the bug reports and their triage process in open-source software systems,"The issue tracking system (ITS) is a rich data source for data-driven decision-making. Different characteristics of bugs, such as severity, priority, and time to fix, provide a clear picture of an ITS. Nevertheless, such information may be misleading. For example, the exact time and the effort spent on a bug might be significantly different from the actual reporting time and the fixing time. Similarly, these values may be subjective, e.g., severity and priority values are assigned based on the intuition of a user or a developer rather than a structured and well-defined procedure. Hence, we explore the evolution of the bug dependency graph together with priority and severity levels to explore the actual triage process. Inspired by the idea of the ``Wayback Machine ``for the World Wide Web, we aim to reconstruct the historical decisions made in the ITS. Therefore, any bug prioritization or bug triage algorithms/scenarios can be applied in the same environment using our proposed ITS Wayback Machine. More importantly, we track the evolutionary metrics in the ITS when a custom triage/prioritization strategy is employed. We test the efficiency of the proposed algorithm using data extracted from three open-source projects. Our empirical study sheds light on the overlooked evolutionary metrics - e.g., overdue bugs and developers' loads - which are facilitated via our proposed past-event re-generator.

Treatments to motivate high-skilled developers,"We study how OSS project owners can manage their repositories so as to motivate particularly high-skilled coders to exert continuous effort after joining a project. Drawing on literature from personnel economics, we lay out how coders' skill level affects their selection for a focal project in the first place. In turn, we theorize how projectspecific norms and quality aspirations that developers learn about after joining an OSS project represent treatments that varyingly entice developers to contribute more code conditional on their skill level. Based on a custom-tailored dataset merging GitHub and Stack Overflow data for almost 50,000 contributor-project-month observations, we find that repository owners are able to motivate their most talented volunteer contributors when they (1) show no visible commercial orientation while managing their projects, (2) show generosity in accepting external contributions, and (3) provide fast feedback.

Investigating the inactivity of OSS core developers in GitHub,"Several Open-Source Software (OSS) projects depend on the continuity of their development communities to remain sustainable. Understanding how developers become inactive or why they take breaks can help communities prevent abandonment and incentivize developers to come back. In this paper, we propose a novel method to identify developers' inactive periods by analyzing the individual rhythm of contributions to the projects. Using this method, we quantitatively analyze the inactivity of core developers in 18 OSS organizations hosted on GitHub. We also survey core developers to receive their feedback about the identified breaks and transitions. Our results show that our method was effective for identifying developers' breaks. About 94\\% of the surveyed core developers agreed with our state model of inactivity; 71\\% and 79\\% of them acknowledged their breaks and state transition, respectively. We also show that all core developers take breaks (at least once) and about a half of them (similar to 45\\%) have completely disengaged from a project for at least one year. We also analyzed the probability of transitions to/from inactivity and found that developers who puce their activity have a similar to 35 to similar to 55\\% chance to return to an active state; yet, if the break lasts for a year or longer, then the probability of resuming activities drops to similar to 21-26\\%, with a similar to 54\\% chance of complete disengagement. These results may support the creation of policies and mechanisms to make OSS community managers aware of breaks and potential project abandonment.",10.1007/s10664-021-10012-6

Practitioners and researchers need to understand more about the phenomenon; however, studies about women in open source are spread across multiple fields, including information systems, software engineering, and social science. This article systematically maps, aggregates, and synthesizes the state-of-the-art on women's participation in OSS. It focuses on women contributors' representation and demographics, how they contribute, their motivations and challenges, and strategies employed by communities to attract and retain women. We identified 51 articles (published between 2000 and 2021) that investigated women's participation in OSS. We found evidence in these papers about who are the women who contribute, what motivates them to contribute, what types of contributions they make, challenges they face, and strategies proposed to support their participation. According to these studies, only about 5\\% of projects were reported to have women as core developers, and women authored less than 5\\% of pull-requests, but had similar or even higher rates of pull-request acceptances than men. Women make both code and non-code contributions, and their motivations to contribute include learning new skills, altruism, reciprocity, and kinship. Challenges that women face in OSS are mainly social, including lack of peer parity and non-inclusive communication from a toxic culture.

Often MALDI-MS data do not includetandem MS fragmentation data, and thus the identification of compoundsin samples requires external databases so that the accurate mass ofdetected signals can be matched to known molecular compounds. Mostrelevant MALDI-MS software tools developed to confirm compound identificationsare focused on small molecules (e.g., metabolites,lipids) and cannot be easily adapted to protein data due to theirmore complex isotopic distributions. Here, we present an R packagecalled IsoMatchMS for the automated annotation ofMALDI-MS data for multiple datatypes: intact proteins, peptides, andglycans. This tool accepts already derived molecular formulas or,for proteomics applications, can derive molecular formulas from alist of input peptides or proteins including proteins with post-translationalmodifications. Visualization of all matched isotopic profiles is providedin a highly accessible HTML format called a trelliscope display, whichallows users to filter and sort by several parameters such as matchscores and the number of peaks matched. IsoMatchMS simplifies the annotation and visualization of MALDI-MS data fordownstream analyses.",10.1021/jasms.3c00180

+1827,InProceedings,A Four-Year Study of Student Contributions to OSS vs. OSS4SG with a Lightweight Intervention,"Modern software engineering practice and training increasingly rely on Open Source Software (OSS). The recent growth in demand for professional software engineers has led to increased contributions to, and usage of, OSS. However, there is limited understanding of the factors affecting how developers, and how new or student developers in particular, decide which OSS projects to contribute to, a process critical to OSS sustainability, access, adoption, and growth. To better understand OSS contributions from the developers of tomorrow, we conducted a four-year study with 1,361 students investigating the life cycle of their contributions (from project selection to pull request acceptance). During the study, we also delivered a lightweight intervention to promote the awareness of open source projects for social good (OSS4SG), OSS projects that have positive impacts in other domains. Using both quantitative and qualitative methods, we analyze student experience reports and the pull requests they submit. Compared to general OSS projects, we find significant differences in project selection (p < 0.0001, effect size = 0.84), student motivation (p < 0.01, effect size = 0.13), and increased pull-request acceptance rates for OSS4SG contributions. We also find that our intervention correlates with increased student contributions to OSS4SG (p < 0.0001, effect size = 0.38). Finally, we analyze correlations of factors such as gender or working with a partner. Our findings may help improve the experience for new developers participating in OSS4SG and the quality of their contributions. We also hope our work helps educators, project leaders, and contributors to build a mutually-beneficial framework for the future growth of OSS4SG.",10.1145/3611643.3616250

Its implementation involves three main components: numerical analysis using the Finite Element Method (FEM), sensitivity analysis using an Adjoint method and an optimization solver. In order to allow the automated numerical solution of Partial Differential Equations (PDEs) and perform a sensitivity analysis, FEniCS and Dolfin Adjoint software are used as tools, which are open-source code. For the optimization process, Ipopt (Interior Point OPTimizer) is used, which is a software package for nonlinear optimization scale designed to find (local) solutions of mathematical optimization problems. The topological optimization method used is based on the SIMP-Solid Isotropic Material with Penalization interpolation. The considered problem is the minimization of compliance/maximization of stiffness, considering the examples of recurrent structures in the literature in 2D and 3D. A density filtering algorithm based on Helmholtz formulation is used.

+1833,Article,A Smart Factory Architecture Based on Industry 4.0 Technologies: Open-Source Software Implementation,"The Smart Factory has been a concept studied during the last decade that has not been standardized yet; for this reason, the academy and industry have developed a wide variety of new architectures that describe the integration of elements for digitization and interconnection. The present research aims to introduce a new architecture proposal for migrating traditional (automation) to smart (digitization) factories, implemented through open-source software. The proposed architecture is integrated, for the first time, by the interconnection of six main elements: cyber-physical systems, edge computing, artificial intelligence, cloud computing, data analytics, and cybersecurity; the research describes in detail their definitions, sub-elements, the interconnection between elements, and the minimum requirements for implementation. The test of the proposed smart factory was done through a scale smart factory pilot testing for a pick and place process, where the assembly of wood pieces from the geometric Tangram's puzzle was required; for this reason, the pilot testing includes a six-degree-of-freedom robot arm, a conveyor, a vision system, and a storage area. The case study conducted in this research allowed the assembly of four puzzles (fish, house, rocket, and swan) that were assembled with four different batches of pieces. The implementation allowed testing flexibility and adaptability. The final assembly reports included the status of assembly, the number of pieces assembled, the number of pieces stored, the assembly sequence, and the assembly time. Similarly, the development of the SCADA system allowed asset control as well as asset monitoring. The KPIs of the assembly process measured productivity (OTD) and time tracking (ATCT and TA) of the 16 tests, founding that the interconnection and digitization of the scale manufacturing cell were fully integrated and allowed repeatability; the proposed SF architecture represents an alternative for the small and medium automated factories to achieve interconnection and digitization, and it is ready to be tested in a more complex scenario.",10.1109/ACCESS.2023.3316116
+1834,Article,A novel method for signal labeling and precise location in a variable parameter milling process based on the stacked-BiLSTM-CRF and FLOSS,"Unlabeled time series signals collected during manufacturing typically have low value density and must be labeled and intercepted according to the specific application scenario. During variable-parameter milling, particularly high-precision machining, machining parameters vary, and associated discrepancies in vibration signals are small. In this scenario, signal features that are extracted by hand or via deep learning methods cannot typically distinguish machining states via classification models. To solve this problem, a sequence labeling model developed using a stacked bidirectional long short-term memory network with a conditional random field layer (stacked-BiLSTM-CRF) is proposed in this study to automatically label and intercept vibration signals. The stacked BiLSTM receives the shallow features obtained by the short-time Fourier transform of the vibration signals and then outputs the extracted deep features to capture the before and after dependence of the signals. The stacked BiLSTM is then extended by stacking a CRF layer to explicitly model the dependence of signal labels. In a more accurate labeling scenario, the fast low-cost online semantic segmentation algorithm (FLOSS) is used to acquire more fine-grained signal boundary locations after obtaining the frame-level signal label using the stacked BiLSTM-CRF model. In addition, to evaluate model performance, a novel evaluation index for signal labeling is proposed. The feasibility and effectiveness of the proposed method are verified using the vibration signals collected from variable parameter cutting experiments, and results show that the proposed model achieves the best labeling performance of tested methods in nearly all scenarios.",10.1016/j.aei.2022.101850
+1835,Article,A semantic model to publish open source software on the web of data,"Purpose The purpose of the paper is to propose a semantic model for describing open source software (OSS) in a machine-human understandable format. The model is extracted to support source code reusing and revising as the two primary targets of OSS through a systematic review of related documents. Design/methodology/approach Conducting a systematic review, all the software reusing criteria are identified and introduced to the web of data by an ontology for OSS (O4OSS). The software semantic model introduced in this paper explores OSS through triple expressions in which the O4OSS properties are predicates. Findings This model improves the quality of web data by describing software in a structured machine-human readable profile, which is linked to the related data that was previously published on the web. Evaluating the OSS semantic model is accomplished through comparing it with previous approaches, comparing the software structured metadata with profile index of software in some well-known repositories, calculating the software retrieval rank and surveying domain experts. Originality/value Considering context-specific information and authority levels, the proposed software model would be applicable to any open and close software. Using this model to publish software provides an infrastructure of connected meaningful data and helps developers overcome some specific challenges. By navigating software data, many questions which can be answered only through reading multiple documents can be automatically responded on the web of data.",10.1108/AJIM-09-2021-0280
+1837,Article,A silk-floss tree (Ceiba speciosa) provides an oasis for floral visitors in an otherwise hostile suburban-farmland environment,"Keystone components in green urban spaces can make a big difference in supporting either impoverished or rich animal communities. Trees that produce thousands of flowers at densities higher than that of herbs and produce much more nectar than the latter can be such keystone structures. However, there is a lack of specific information on trees, both native and alien, and their flower visitors in urban/suburban contexts, which blurs the conservation role that such species can perform. In 2019 and 2020, we thoroughly recorded the flower visitors to a silk-floss tree in suburban Guadalajara, Mexico. To our knowledge, this is the first comprehensive inventory of silk-floss tree flower visitors. We documented 79 species/morphospecies of insects; eight of birds, and one of mammals visiting the flowers. All, except two, are native to the region; three are endemic/quasi-endemic to Mexico. Besides direct and indirect floral resources, the silk-floss tree offered perches, resting/hiding cover, nesting substrate, and seed fibres used by several birds, and feeding substrate for gleaning insectivorous birds. Four species are on one or more conservation listings: monarch butterfly (endangered), pink-spotted swallowtail (vulnerable), sparkling-tailed hummingbird (threatened), and lesser long-nosed bat (near-threatened). Our data supports that small patches can enhance the quality of urban green spaces, and that rather than geographic origin, flower output drives visitation. Alien trees can be pollination enhancement `devices' for imperilled pollination networks. Silk-floss trees are a potential option for conservation-oriented urban greening, as well as to contribute to enhancing human enjoyment of nature, and provide opportunities for public outreach.",10.1080/00222933.2023.2284996

+1839,Article,AirSeaFluxCode: Open-source software for calculating turbulent air-sea fluxes from meteorological parameters,"The turbulent exchanges, or fluxes, of heat, moisture and momentum between the atmosphere and the ocean play a crucial role in the Earth's climate system. Direct measurements of turbulent fluxes are very challenging and sparse, and do not span the full range of environmental conditions that exist over the ocean. This means that empirical ``bulk formulae{''} parameterizations that relate direct flux observations to concurrent measurements of the mean meteorological and sea surface variables contain considerable uncertainty. In this paper, we present a Python 3.6 (or higher) open-source software package ``AirSeaFluxCode{''} for the computation of the heat (latent and sensible) and momentum fluxes. Ten different parameterizations are included, each based on published descriptions or code and each derived from a different set of observations, or different assumptions about the turbulent exchange processes. They represent a range of current expert opinion on how the fluxes depend on mean properties and can be used to explore uncertainty in calculated fluxes. AirSeaFluxCode also allows the adjustment of the mean meteorological input parameters (air temperature, humidity and wind speed) from the height at which they are obtained to a user-defined output height. This height adjustment enables the comparison of measurements, or model-derived values, made at different heights above sea-level. The parameterizations calculate the fluxes using input parameters that are relatively easily to measure, or are available as model output: wind speed, air temperature, sea surface temperature, atmospheric pressure and humidity. Where original code is available we have compared its output with that of AirSeaFluxCode. Any changes made to increase consistency across algorithms by standardizing computational methods or calculation of meteorological variables, for example, are discussed and the impacts quantified: these are shown to be insignificant except for a few cases where conditions were extreme, and AirSeaFluxCode is shown to be robust. We also investigate the impact on the fluxes caused by different assumptions about the exchange processes, or the choices inherent in the implementation of the parameterizations. For example, sea surface temperature usually refers to data typically obtained at depths of between 1 and 10 m. However, since some parameterizations require a ``skin{''} sea surface temperature, code that adjusts temperature at depth to skin temperature is included: this has a very significant impact on the fluxes. Selecting a parameterization that is appropriate for the available sea surface temperature will avoid the need to adjust the sea temperature data and the uncertainties associated with that adjustment, and will also avoid the biases due to use of the ``wrong{''} measure of temperature. Significant differences also resulted from assumptions about the size of reduction in sea surface humidity to account for salinity effects: the uncertainty in the reduction factor needs to be quantified in future analyses. Fluxes in extreme conditions are particularly uncertain since the transfer coefficients in the different parameterizations vary most at very high and very low wind speeds. Low wind speeds are also challenging for numerical implementation since choices have to be made regarding: convergence criteria for the iterative calculation, inclusion of a parameterization for convective gustiness, or application of ad hoc limits to various parameters. All of these choices can significantly affect the flux estimates for light winds.",10.3389/fmars.2022.1049168

Managing an e-commerce website used to be challenging, but thanks to advances in technology, it is now feasible to successfully manage an e-commerce website by choosing the right e-commerce platform. Almost every company nowadays has a website, particularly those that cater to digital or internet-based clientele. Starting a modest online store is straightforward, but as the company expands, the expectations get more specialized, and they are not met. Unfortunately, ``ready to go{''} solutions are typically resistive to acceptance, meaning that all individual changes are not warmly welcomed. This study analyzed and compared the two types of software used in building e-commerce websites in the Philippines' popular websites and detected the current web technologies and conducted an online survey using qualitative approach with the participation of experts and familiar with e-commerce system. It also to identified what are the things need to consider when choosing software. As results from the surveys on e-commerce software, the most significant variables to consider when choosing an ecommerce software, whether proprietary or open source, are security and performance, followed by time and budget when establishing an e-commerce website.",10.12720/jait.14.3.426-430
+1841,InProceedings,An Empirical Study of License Conflict in Free and Open Source Software,"Free and Open Source Software (FOSS) has become the fundamental infrastructure of mainstream software projects. FOSS is subject to various legal terms and restrictions, depending on the type of open source license in force. Hence it is important to remain compliant with the FOSS license terms. Identifying the licenses that provide FOSS and understanding the terms of those licenses is not easy, especially when dealing with a large amount of reuse that is common in modern software development. Since reused software is often large, automated license analysis is needed to address these issues and support users in license compliant reuse of FOSS. However, existing license assessment tools can only identify the name and quantity of licenses embedded in software and thus cannot identify whether the licenses are being used safely and correctly. Moreover, they cannot provide a comprehensive analysis of the compatibility and potential risk that come with the term conflicts. In this paper, we propose DIKE, an automated tool that can perform license detection and conflict analysis for FOSS. First, DIKE extracts 12 terms under 3,256 unique open source licenses by manual analysis and Natural Language Processing (NLP) and constructs a license knowledge base containing the responsibilities of the terms. Second, DIKE scans all licenses from the code snippet for the input software and outputs the scan results in a tree structure. Third, the scan results match the license knowledge base to detect license conflicts from terms and conditions. DIKE designs two solutions for software with license conflicts: license replacement and code replacement. To demonstrate the effectiveness of DIKE, we first evaluate with the term extraction and responsibility classification, and the results show that their F1-scores reach 0.816 and 0.948, respectively. In addition, we conduct a measurement study of 16,341 popular projects from GitHub based on our proposed DIKE to explore the conflict of license usage in FOSS. The results show that 1,787 open source licenses are used in the project, and 27.2\\% of licenses conflict. Our new findings suggest that conflicts are prevalent in FOSS, warning the open source community about intellectual property risks.",10.1109/ICSE-SEIP58684.2023.00050

A good understanding of how developers work together could positively impact software development practices. In this paper, we investigate the collaboration habits of developers in project files by leveraging the World of Code (WoC) dataset and GitHub API. We first identify the collaboration level of developers within the project files, such as the source, test, documentation, and build files, using the Author Cross Entropy (ACE). From the results we find out that test files report the highest degree of collaboration among the developers, perhaps because collaboration is critical to ensure convergence of functionality tests. Furthermore, the source code files show the least degree of collaboration, perhaps because of code ownership and the complexity and difficulty in code modification. Secondly, given the widespread usage of the Python programming language, we investigate the Python code tokens that are more prone to change and collaboration. Our findings offer insights into the specific project files and Python code tokens that developers typically collaborate on in the opensource community. This information can be used by researchers and developers to enhance existing collaboration platforms and tools.",10.1109/MSR59073.2023.00054
+1844,InProceedings,An Exploration of Technical Debt over the Lifetime of Open-Source Software,"Technical debt represents unwanted issues that result from decisions made to speed up the design or implementation of software at the expense of resolving existing issues. Like financial debt, it consists of the principal and an interest. Debt is usually paid back through code rewrites, refactoring, or the introduction of test code. When unchecked, interest can accumulate over time and lead to development crises where focus and resources must be shifted to resolve existing debt before the development process can be resumed. Existing software tooling allows practitioners to quantify the level of debt and identify its sources, allowing decision makers to measure and control it. We propose a detailed exploration of the characteristics of source code technical debt over the lifetime of several popular open-source applications. We employed a SonarQube instance configured for longitudinal analysis to study all publicly released versions of the target applications, amounting to over 15 years' worth of releases for each. We found that a small number of issue types were responsible for most of the debt and observed that refactoring reduced debt levels across most application packages. We observed increased variance in technical debt distribution and composition in early application versions, which lessened once applications matured. We addressed concerns regarding the accuracy of SonarQube estimations and illustrated some of its limitations. We aim to continue our research by including additional tools to characterize debt, leverage existing open data sets and extend our exploration to include additional applications and types of software.",10.1007/978-3-031-36597-3\\_14

Clients may struggle to select the best OSS-LMS package from a wide range of options, leading to a complex multi-criteria group decision -making (MCGDM) problem. This evaluates OSS-LMS packages based on several criteria like us-ability, functionality, e-learning standards, reliability, activity tracking, course development, assess-ment, backup and recovery, error reporting, efficiency, operating system compatibility, computer -managed instruction, authentication, authorization, troubleshooting, maintenance, upgrading, and scalability. Handling uncertain data is a vital aspect of OSS-LMS package evaluation. To tackle MCGDM issues, this study presents a consensus weighted sum product (c-WASPAS) method which is applied to an educational OSS-LMS package selection problem to evaluate four OSS-LMS pack-ages, namely ATutor, eFront, Moodle, and Sakai. The findings indicate that the priority order of alternatives is Moodle > Sakai > eFront > ATutor and, therefore, MOODLE is the best OSS-LMS package for the case study. A sensitivity analysis of criteria weights is also conducted, as well as a comparative study, to demonstrate the effectiveness of the proposed method. It is essential to note that proper OSS-LMS package evaluation is crucial to avoid negative impacts on organizational per-formance. By addressing MCGDM issues and dealing with uncertain information, the c-WASPAS method presented in this study can assist clients in selecting the most appropriate OSS-LMS pack-age from multiple alternatives. The findings of this study can benefit educational institutions and other organizations that rely on OSS-LMS packages to run their operations.",10.15388/23-INFOR523

Chemical modification of glycans (derivatization) can enhance ionization, enable semi-quantitation, and assist in linkage identification. However, the mass changes incurred by novel and more recently developed derivatizations are not accommodated by most spectral assignment programs, necessitating manual assignment which increases both the difficultly and the likelihood of error.

This study investigated the potential feasibility of using candy floss spinning (CFS) technique to generate new PLA-clay bionanocomposites with exfoliated morphology. The dispersion of nanoclay in PLA-clay bionanocomposites prepared by internal mixing, with and without candy floss spinning, as a masterbatch (having 20\\%wt nanoclay) and then diluted in twin screw extruder to different percentage of nanoclay loadings (1\\%, 2\\% and 4\\%, w/w), were compared in terms of their structures and properties.

Overall, mechanical, and thermal properties of the bionanocomposites were improved in comparison to the neat PLA. Furthermore, XRD study exposed that bionanocomposites pre -pared by the CFS technique showed the disappearance of d001 basal peak, confirming generation of exfoliated microstructures, whereas the samples prepared solely by the internal mixing technique showed intercalated structure.

+1855,InProceedings,ColEmo: A Flexible Open Source Software Interface for Collecting Emotion Data,"Data collection is a critical challenge in Emotion Recognition (ER), especially as demand grows for in-the-wild data that includes contextual information. The collection of data is continuously needed to investigate new ER modalities, sensors, stimuli, models, and methods. This necessitates the development of tools and frameworks that facilitate emotion data collection. In this paper, we introduce ColEmo, an open-source software interface for collecting emotion data. ColEmo was developed using Flutter allowing it to be compiled for both desktop and mobile devices. The architecture and interface of ColEmo provides a high degree of flexibility to be customized or extended to suit specific experiment requirements. We tested ColEmo in an ER data collection study which was extended to include Voice Activity Detection (VAD) and motion context, demonstrating its effectiveness in lab environments. Further investigation is recommended to evaluate ColEmo's potential for in-the-wild data collection setups.",10.1109/ACIIW59127.2023.10388161
+1856,Article,Comparative Evaluation of Cleaning Efficacy of Interdental Brush and Interdental Floss in Orthodontics Patients From Vidarbha Region: An Interventional Study,"Background Plaque and dental caries are the primary agents causing gingival and periodontal diseases, eventually progressing into tooth loss. If oral hygiene practice is poor, plaque easily accumulates on the tooth surface, especially in interproximal areas. To maintain a good oral environment, it is mandatory to remove or at least reduce the percentage of plaque formation from the oral cavity. To achieve this, interdental aids should be used along with toothbrushes, as cleansing the teeth only with a toothbrush is not effective. Various interdental aids, like interdental brushes, floss, toothpicks, etc., are now available on the market. The objective of the current survey was to rate knowledge as well as make a comparison between the cleaning effectiveness of interdental brushes and interdental floss to determine which was better at reducing plaque accumulation and, subsequently, dental caries. The survey was accessed by measuring individual plaque and gingival index before and after using interdental cleaning aids.Methodology The objective of the survey was to evaluate and analyze the efficiency of interdental brushes and interdental floss in maintaining oral hygiene among orthodontic patients residing in the Vidarbha region. After receiving approval from the Ethical Committee DMIHER(DU)/IEC/2023/721, a study was conducted over a 30-day period, focusing on a group of 100 individuals aged between 15 and 30 years, and their assessments were analyzed. The patient was briefed about the study and asked to make use of an interdental brush and interdental floss. The gingival index and plaque index were calculated on the same patients before and after the use of the interdental brush and interdental floss to determine which was better at reducing plaque accumulation on the surface of teeth. Descriptive analysis, unpaired for intergroup comparison, and paired T-tests for intragroup comparison were used. The software used was SPSS 24.0 (IBM Corp., Armonk, NY) and GraphPad Prism 7.0 (GraphPad Software, Inc., La Jolla, CA).Result Everyone's tooth surfaces naturally develop a thin layer of plaque biofilm, but the presence of heavy plaque deposits on teeth indicates poor dental hygiene, which can lead to various oral health issues. Failure to improve dental hygiene status can result in problems such as halitosis, gingival issues, periodontal disease, and eventually tooth loss. Dentists play a crucial role in raising awareness about these concerns among their patients and providing education on effective oral care practices, including the use of interdental aids in conjunction with toothbrushes. When comparing the effectiveness of interdental brushes and dental floss in removing plaque, interdental brushes have been found to be more efficient. They not only excel in plaque removal but also contribute to a reduction in gingival problems. The statistical analysis supports this, with a significant p-value of less than 0.01 for both the plaque index and gingival index when using interdental brushes, indicating their superior performance in maintaining oral health.Conclusion The study will help every individual improve their oral hygiene status with the help of an interdental aid and a toothbrush. This will reduce the chances of having gingival and periodontal diseases and eventually reduce the risk of tooth loss.",10.7759/cureus.46191
+1857,Article,Comprehensive assessment of open source software ecosystem health,"Recent surveys expose that the use of Open Source Software (OSS) is increasingly becoming a need for organizations in their development projects. However, deciding a proper OSS to be adopted or to contribute to its development is a complex and error-prone task. Analyzing the OSS ecosystem (OSSECO) health may help providing information about: (1) the OSS itself (number of commits, days after the last release, etc.); and (2) their main actors (number of contributors, partners, etc.). There exist proposals that go further and provide aggregated high-level indicators (e.g. visibility as an aggregation of number of community events, number of partners, and other metrics). Nevertheless, there is a lack of useful OSSECO analysis tools to ease the decision making on which OSSECO has the health required by a potential OSS adopter or contributor. In this work, we provide OSS-CARE (OSSeCo heAlthy monitoR and analysEr), an OSS-independent, fully automatic, and real-time framework to assess OSSECO's health. OSS-CARE supports defining the ecosystem health objectives of potential OSS adopters, OSS contributors, and even OSS managers to inspect their provided health. These objectives are defined based on a well-established model characterizing health metrics that can be potentially aggregated by using a Bayesian network technique. Moreover, the integrated monitoring and analysis components perform an automated assessment of OSSECO's health by checking the fulfillment of the required health objectives. Furthermore, the result is shown in an appealing dashboard that may ease the complex decision making of which OSS to choose.",10.1016/j.iot.2023.100808

However, the collaborative structure of these communities largely remains unclear, partly due to the enormous scale of data to be gathered, processed, and analyzed. In this work, we utilize the World Of Code dataset, which contains commit activity data for millions of OSS projects, to build collaboration networks for ten popular programming language ecosystems, containing in total over 290M commits across over 18M projects. We build a collaboration graph representation for each language ecosystem, having authors and projects as nodes, which enables various forms of social network analysis on the scale of language ecosystems. Moreover, we capture the information on the ecosystems' evolution by slicing each network into 30 historical snapshots. Additionally, we calculate multiple collaboration metrics that characterise the ecosystems' states.

+1859,Article,Cross-status communication and project outcomes in OSS development A language style matching perspective,"Context The success of an open source software (OSS) project requires effective communication among its members. Given that OSS projects often have established social status systems, such communication may happen between individuals of different statuses, particularly, elite developers with project management privileges and ordinary project contributors. They communicate with each other onmany essential activities, e.g., bug fixing, code review, etc., thus having profound influences on project outcomes. Objectives We seek to develop an understanding of cross-status communication from a perspective of language stylematching among developers of different status, and its relationships with an OSS project's outcomes in terms of productivity and quality. Method We approach the above research objectives with the language stylematching (LSM) tool, which measures the similarities of cross-status communication inmultiple language style features. We first dynamically identify elite developers having project administration privileges for each sampled project. Then, we capture the cross-status communication between elite and non-elite developers; and calculate the LSM features of these two groups of individuals. The LSM variables, together with project outcomes, were used to fit regression models to analyze potential relationships between cross-status communication's language matching and project outcomes. Results Using over 275,000 collected conversations, our analyses yield rich insights into cross-status communication in open source development. First, our results reveal that the elite and non-elite developers exhibit quite similar linguistic patterns in using certain categories of words. Second, we explore the relationships between linguistic similarity in cross-status communication and project outcomes. The regression results are generally negative, indicating there might be very limited significant relationships between cross-status communication's language matching and project outcomes, with a few exceptions. Limitations The study has several limitations. First, it considers projects hosted on GitHub only. Second, to ensure data availability, our sample is drawn from top projects, thus not representing all projects. Third, we only consider a limited number of linguistic features, and indicators for project outcomes.

+1861,Article,DeepQMC: An open-source software suite for variational optimization of deep-learning molecular wave functions,"Computing accurate yet efficient approximations to the solutions of the electronic Schrodinger equation has been a paramount challenge of computational chemistry for decades. Quantum Monte Carlo methods are a promising avenue of development as their core algorithm exhibits a number of favorable properties: it is highly parallel and scales favorably with the considered system size, with an accuracy that is limited only by the choice of the wave function Ansatz. The recently introduced machine-learned parametrizations of quantum Monte Carlo Ansatze rely on the efficiency of neural networks as universal function approximators to achieve state of the art accuracy on a variety of molecular systems. With interest in the field growing rapidly, there is a clear need for easy to use, modular, and extendable software libraries facilitating the development and adoption of this new class of methods. In this contribution, the DEEPQMC program package is introduced, in an attempt to provide a common framework for future investigations by unifying many of the currently available deep-learning quantum Monte Carlo architectures. Furthermore, the manuscript provides a brief introduction to the methodology of variational quantum Monte Carlo in real space, highlights some technical challenges of optimizing neural network wave functions, and presents example black-box applications of the program package. We thereby intend to make this novel field accessible to a broader class of practitioners from both the quantum chemistry and the machine learning communities.",10.1063/5.0157512
+1862,Article,Development and Implementation of Element Deletion Algorithm into an Open-Source Software Based on the Fracture Locus of Materials,"An accurate fracture simulation is often associated with how reliably the material model is represented. Hence, many models dealing with the calibration of ductile damage of materials have already been developed to predict failure initiation. Nevertheless, the challenge remains in obtaining an accurate representation of the fracture growth. Herein, an element deletion algorithm is developed and implemented into finite element open-source software. The deleted elements are replaced by new cells made of a virtual low-stiffness material. To better visualize the failure progression, the final model excludes these virtual cells from the representation. The functionality of the algorithm is tested through a series of two-dimensional simulations on three different geometries with a well-known behavior under uniaxial tension. Moreover, the failure response of a three-dimensional lattice structure is numerically investigated and compared against experimental data. The results of the two-dimensional simulations showed the capability of the algorithm to predict the onset of failure, crack nucleation, and fracture growth. Similarly, the onset and the initial fracture region were accurately captured in the three-dimensional case, with some convergence issues that prevent the visualization of the fracture growth. Overall, the results are encouraging, and the algorithm can be improved to introduce other computational functionalities.",10.3390/ma16010187

Historically, society's response to a problem is based on funding availability, current threat, and public outcry. Achieving this is largely dependent on the knowledge of the factors that are resulting in compromised water sources. These factors are constantly changing as novel contaminants are introduced into surface water sources. As we are in the information age, the interest in contaminants of emerging concern (CEC) is gaining ground. Whilst research is being conducted to identify contaminants in South African water sources, the research outputs and available information is not collated and presented to the science community and stakeholders in readily available formats and platforms. Current research outcomes need to be made known to regulators in order to develop environmental laws.

This article aims at an analysis of the literature related to LAM institutions on open-source software used in digital curation. The undertaken research was an attempt to check the interest in this issue in publications registered in the BASE multi-search database. The research material collected during library searches was analysed using simple bibliometric methods. Based on literature analysis, this paper indicates a growing interest in digital curation in LAM institutions in the context of open-source software.

+1865,Article,DisGUVery: A Versatile Open-Source Software for High-Throughput Image Analysis of Giant Unilamellar Vesicles,"Giant unilamellar vesicles (GUVs) are cell-sized aqueous compartments enclosed by a phospholipid bilayer. Due to their cell-mimicking properties, GUITs have become a widespread experimental tool in synthetic biology to study membrane properties and cellular processes. In stark contrast to the experimental progress, quantitative analysis of GUV microscopy images has received much less attention. Currently, most analysis is performed either manually or with custom-made scripts, which makes analysis time-consuming and results difficult to compare across studies. To make quantitative GUV analysis accessible and fast, we present DisGUVery, an open-source, versatile software that encapsulates multiple algorithms for automated detection and analysis of GUVs in microscopy images. With a performance analysis, we demonstrate that DisGUVery's three vesicle detection modules successfully identify GUVs in images obtained with a wide range of imaging sources, in various typical GUV experiments. Multiple predefined analysis modules allow the user to extract properties such as membrane fluorescence, veside shape, and internal fluorescence from large populations. A new membrane segmentation algorithm facilitates spatial fluorescence analysis of nonspherical vesicles. Altogether, DisGUVery provides an accessible tool to enable high-throughput automated analysis of GUVs, and thereby to promote quantitative data analysis in synthetic cell research.",10.1021/acssynbio.2c00407

(2021),"Research SummaryWe extend the ownership competence framework by discussing how the features of the institutional environment influence the exercise of ownership competence. Two amendments are proposed. First, we add a new dimension to the framework, institutional competence (“where to own”), which denotes that individuals and firms have heterogeneous abilities to assess how an institutional environment affects the potential uses of a resource. Second, we argue that institutional uncertainty moderates the three original dimensions of the framework, impairing the exercise of ownership competence of some entrepreneurs and firms more than of others. We use examples from the literature to illustrate our arguments. We also discuss the implications of our analysis.Managerial SummaryThe ownership competence framework is built on the idea that business owners have different abilities to deploy resources and create value. Starting from this contribution, we shed light on the specific role that the institutional environment plays in the exercise of ownership competence. We argue that the ownership competence framework must explicitly consider where ownership takes place in order to explain the actions of entrepreneurs and firms. We also claim that institutional uncertainty can influence value creation in more subtle ways than indicated in the original formulation of the ownership competence framework. All in all, this article paves the way for institutional aspects to be considered more explicitly in the strategic analysis of ownership.",10.1002/smj.3462

+1871,InProceedings,Do CONTRIBUTING Files Provide Information about OSS Newcomers' Onboarding Barriers?,"Effectively onboarding newcomers is essential for the success of open source projects. These projects often provide onboarding guidelines in their `CONTRIBUTING' files (e.g., CONTRIBUTING.md on GitHub). These files explain, for example, how to find open tasks, implement solutions, and submit code for review. However, these files often do not follow a standard structure, can be too large, and miss barriers commonly found by newcomers. In this paper, we propose an automated approach to parse these CONTRIBUTING files and assess how they address onboarding barriers. We manually classified a sample of files according to a model of onboarding barriers from the literature, trained a machine learning classifier that automatically predicts the categories of each paragraph (precision: 0.655, recall: 0.662), and surveyed developers to investigate their perspective of the predictions' adequacy (75\\% of the predictions were considered adequate). We found that CONTRIBUTING files typically do not cover the barriers newcomers face (52\\% of the analyzed projects missed at least 3 out of the 6 barriers faced by newcomers; 84\\% missed at least 2). Our analysis also revealed that information about choosing a task and talking with the community, two of the most recurrent barriers newcomers face, are neglected in more than 75\\% of the projects. We made available our classifier as an online service that analyzes the content of a given CONTRIBUTING file. Our approach may help community builders identify missing information in the project ecosystem they maintain and newcomers can understand what to expect in CONTRIBUTING files.",10.1145/3611643.3616288

A family of electronic shooting simulators ``STrIzh{''} of four levels of implementation: initial, basic, professional and special is described. Structural diagrams of different configurations are given, functional purpose and capabilities of each level of simulators are shown. The initial level allows independent assemble the simulator from publicly available elements (laptop, webcam, weapon layouts, IR LEDs), which can contribute to widespread use both in schools and at home, but is low in accuracy and manufacturabili (requires daily calibration). The basic level also allows independent assemble the simulator, and less publicly available elements (laptop, projector, mockup weapons, laser emitters, FHD camera), which allows to be used both in schools and in DOSAAF structures, and has acceptable accuracy and manufacturability (a weekly calibration is enough, but assembling a mock-up weapon with laser emitters requires adjustments). It is recommended to limit the special level to virtual reality simulators, including a helmet with a smartphone and a mockup of a weapon with its smartphone which also contributes to its public availability and widespread use. The simulator software algorithm should fully support all implementation levels with different configurations and include a multimedia shooting training system. Mathematical models of external ballistics of thrown equipment for Kalashnikov assault rifle, Makarov pistol, hand-held anti-tank grenade launcher 7 products are described in detail, taking into account changes in atmospheric factors (temperature, air pressure, wind force) and dispersion of various types of ammunition.

Forty healthy patients who met the necessary eligibility criteria were allocated by block randomization to either the test group (20 patients) or control group (20 patients). Cone beam computed tomography scans were obtained at enrolment (T0), immediately after surgery (T1), at delivery of the prosthetic rehabilitation (T2), and 1 year after functional implant loading (T3). Mean differences were expressed with the 95\\% confidence interval; significance was set at P < 0.05. ESBG was significantly increased with Bio-Oss Collagen compared with no grafting material at T1, T2, and T3 (P < 0.001). A gradual decrease in ESBG was observed over time with both treatment modalities (P < 0.001), which diminished the difference between the test and control groups at T2 and T3. ESBG was observed to be positively correlated with implant protrusion length and negatively correlated with the residual bone height. In osteotome-mediated sinus floor elevation, the application of Bio-Oss Collagen underneath the elevated Schneiderian membrane improved ESBG significantly when compared with no grafting material. However, the increased ESBG seems not to have positively improved the treatment outcomes in terms of the implant stability quotient or the survival of the implants or suprastructures.",10.1016/j.ijom.2023.03.009

We describe four active Education-Oriented H/FOSS projects and introduce a framework for illustrating different models of H/FOSS engagement. The framework is used to structure a discussion of the considerations and trade-offs of different engagement models, and highlights particular models that have been used to engage students and faculty in our four Education-Oriented H/FOSS projects. The framework positions projects along dimensions of professor involvement, responsibility for project hosting/management, mode of student knowledge and skill acquisition, and the curricular engagement goals. In doing so it broadly captures trade-offs that exist between the level of institutional resources used and the level of student independence required. It is anticipated this framework and the discussion that it organizes will be useful to faculty a) in evaluating the appropriateness of particular H/FOSS projects for use in their courses and curriculum and b) as guidance to those considering the creation of new Education-Oriented H/FOSS projects.",10.1145/3545945.3569835
+1879,InProceedings,Enhancing OSS Patch Backporting with Semantics,"Keeping open-source software (OSS) up to date is one potential solution to prevent known vulnerabilities. However, it requires frequent and costly testing and may introduce compatibility issues. Consequently, developers often choose to backport security patches to the vulnerable versions instead. Manual backporting is time-consuming, especially for large OSS such as the Linux kernel. Therefore, automating this process is urgently needed to save considerable time. Existing automated approaches for backporting patches involve either automatic patch generation or automatic patch migration. However, these methods are often ineffective and error-prone since they failed to locate the precise patch locations or generate the correct patch, operating only on the syntactic level. In this paper, we propose a patch type-sensitive approach to automatically backport OSS security patches, guided by the patch type and patch semantics. Specifically, our approach identifies patch locations with the aid of program dependency graph-based matching at the semantic level. It further applies fine-grained patch migration and fine-tuning based on patch types. We have implemented our approach in a tool named TSBPORT and evaluated it on a large-scale dataset consisting of 1,815 pairs of real-world security patches for the Linux kernel. The evaluation results show that TSBPORT successfully backported 1,589 (87.59\\%) patches, out of which 587 (32.34\\%) could not be backported by any state-of-the-art approaches, significantly outperforming state-of-the-art approaches. In addition, experiments also show that TSBPORT can be generalized to backport patches in other OSS projects with a success rate of 88.18\\%.",10.1145/3576915.3623188

It is believed that the seed flosses of common milkweed, Asclepias Syriraca, may be a promising reinforcing fiber given its uncommon hollow microstructure that is associated with both high specific properties and outstanding insulating capacities. This study presents an overview of the properties of milkweed floss and its potential use in reinforced-polymer composites. Milkweed flosses from Quebec were analyzed to determine their overall dimensions, density, porosity, coefficient of acoustic absorption, thermal conductivity, thermal resistance, and elastic modulus. In parallel, a portion of milkweed fibers was treated with acetone to modify their surface, and the properties of the treated fibers were measured and compared against the characteristics of the original fibers. Infrared spectroscopy was employed to assess differences between the chemical groups on the surface of treated and native fibers. The treatment with acetone removed fatty acids, waxes, and free sugars from the fibers' surface. The acetone treatment did not affect the fibers' microstructure nor their acoustic absorption capacity. The acetone-treated fibers showed greater thermal resistance and a higher thermal conductivity than native milkweed floss. The elastic modulus of milkweed decreased by nearly 49\\% after the acetone treatment.",10.1080/15440478.2023.2174630

However, users often tend to acquire codes from the community and are reluctant to contribute their knowledge. Integrating the motivational theory and social capital theory, this article intends to explore users' contribution in OSS communities. A mixed method of SEM and fsQCA was used to perform data analysis. We found that intrinsic motivations (flow experience and self-efficacy), extrinsic motivations (perceived reputation and reciprocity), social interaction ties, community identification, and common language positively affect users' contribution intention. Trust has no effect on the contribution intention. The fsQCA results indicated that flow experience, perceived reputation, reciprocity and trust are the common core conditions of four configurations leading to contribution intention.

Although machine learning-based toxicity detection tools trained on domain-specific data have shown promise, their design lacks an understanding of the unique nature and triggers of toxicity in OSS discussions, highlighting the need for further investigation. In this study, we employ Moral Foundations Theory to examine the relationship between moral principles and toxicity in OSS. Specifically, we analyze toxic communications in GitHub issue threads to identify and understand five types of moral principles exhibited in text, and explore their potential association with toxic behavior. Our preliminary findings suggest a possible link between moral principles and toxic comments in OSS communications, with each moral principle associated with at least one type of toxicity.

In this method, the sample collection of strain measurement and deformation change at each measuring point of the flexible thin-walled structure was completed by ANSYS finite element analysis. The outliers were removed by the OCSVM (one-class support vector machine) model, and the unique mapping relationship between the strain value and the deformation variables (three directions of x-, y-, and z-axis) at each point was completed by a neural-network model. The test results show that the maximum error of the measuring point in the direction of the three coordinate axes: the x-axis is 2.01\\%, the y-axis is 29.49\\%, and the z-axis is 15.52\\%. The error of the coordinates in the y and z directions was large, and the deformation variables were small, the reconstructed shape had good consistency with the deformation state of the specimen under the existing test environment. This method provides a new idea with high accuracy for real-time monitoring and shape reconstruction of flexible thin-walled structures such as wings, helicopter blades, and solar panels.",10.3390/mi14040794

Computational intelligence (CI) in general and particle swarm optimization (PSO) algorithms in particular have been shown to accelerate finding optimal printing parameters. Unfortunately, the implementation of CI has been prohibitively complex for noncomputer scientists. To overcome these limitations, this article develops, tests, and validates PSO Experimenter, an easy-to-use open-source platform based around the PSO algorithm and applies it to optimizing recycled materials. Specifically, PSO Experimenter is used to find optimal printing parameters for a relatively unexplored potential distributed recycling and additive manufacturing (DRAM) material that is widely available: low-density polyethylene (LDPE). LDPE has been used to make filament, but in this study for the first time it was used in the open source fused particle fabrication/fused granular fabrication system. PSO Experimenter successfully identified functional printing parameters for this challenging-to-print waste plastic. The results indicate that PSO Experimenter can provide 97\\% reduction in research time for 3D printing parameter optimization. It is concluded that the PSO Experimenter is a user-friendly and effective free software for finding ideal parameters for the burgeoning challenge of DRAM as well as a wide range of other fields and processes.",10.1089/3dp.2022.0012

OSS permits users to access source code for assessment, amendment, and redistribution, which offers low dependency on a vendor without license or maintenance cost. This paper investigates and analyzes OSS adoption factors for ``critical IT infrastructure{''} by conducting a comprehensive review of the relevant literature. Furthermore, this paper proposes a framework that can help the critical IT industry to have increased confidence in OSS. The proposed framework utilizes the organizing logic of the Technology, Organization, and Environment (TOE) framework, recommends factors that were recognized by critically scrutinizing the studies found in the available literature.

+1893,Article,"Free and open-source software for object detection, size, and colour determination for use in plant phenotyping","BackgroundObject detection, size determination, and colour detection of images are tools commonly used in plant science. Key examples of this include identification of ripening stages of fruit such as tomatoes and the determination of chlorophyll content as an indicator of plant health. While methods exist for determining these important phenotypes, they often require proprietary software or require coding knowledge to adapt existing code.ResultsWe provide a set of free and open-source Python scripts that, without any adaptation, are able to perform background correction and colour correction on images using a ColourChecker chart. Further scripts identify objects, use an object of known size to calibrate for size, and extract the average colour of objects in RGB, Lab, and YUV colour spaces. We use two examples to demonstrate the use of these scripts. We show the consistency of these scripts by imaging in four different lighting conditions, and then we use two examples to show how the scripts can be used. In the first example, we estimate the lycopene content in tomatoes (Solanum lycopersicum) var. Tiny Tim using fruit images and an exponential model to predict lycopene content. We demonstrate that three different cameras (a DSLR camera and two separate mobile phones) are all able to model lycopene content. The models that predict lycopene or chlorophyll need to be adjusted depending on the camera used. In the second example, we estimate the chlorophyll content of basil (Ocimum basilicum) using leaf images and an exponential model to predict chlorophyll content.ConclusionA fast, cheap, non-destructive, and inexpensive method is provided for the determination of the size and colour of plant materials using a rig consisting of a lightbox, camera, and colour checker card and using free and open-source scripts that run in Python 3.8. This method accurately predicted the lycopene content in tomato fruit and the chlorophyll content in basil leaves.",10.1186/s13007-023-01103-0

Despite the innovative structures they develop to support the projects, OSS projects and their communities have complex needs and face risks such as getting abandoned. To manage the internal social dynamics and community evolution, OSS developer communities have started relying on written governance documents that assign roles and responsibilities to different community actors. To facilitate the study of the impact and effectiveness of formal governance documents on OSS projects and communities, we present a longitudinal dataset of 710 GitHub-hosted OSS projects with GOVERNANCE.MD governance files.

+1895,InProceedings,Gradient flossing: improving gradient descent through dynamic control of jacobians,"Training recurrent neural networks (RNNs) remains a challenge due to the instability of gradients across long time horizons, which can lead to exploding and vanishing gradients. Recent research has linked these problems to the values of Lyapunov exponents for the forward-dynamics, which describe the growth or shrinkage of infinitesimal perturbations. Here, we propose gradient flossing, a novel approach to tackling gradient instability by pushing Lyapunov exponents of the forward dynamics toward zero during learning. We achieve this by regularizing Lyapunov exponents through backpropagation using differentiable linear algebra. This enables us to ""floss"" the gradients, stabilizing them and thus improving network training. We demonstrate that gradient flossing controls not only the gradient norm but also the condition number of the long-term Jacobian, facilitating multidimensional error feedback propagation. We find that applying gradient flossing prior to training enhances both the success rate and convergence speed for tasks involving long time horizons. For challenging tasks, we show that gradient flossing during training can further increase the time horizon that can be bridged by backpropagation through time. Moreover, we demonstrate the effectiveness of our approach on various RNN architectures and tasks of variable temporal complexity. Additionally, we provide a simple implementation of our gradient flossing algorithm that can be used in practice. Our results indicate that gradient flossing via regularizing Lyapunov exponents can significantly enhance the effectiveness of RNN training and mitigate the exploding and vanishing gradients problem.",NA

+1897,Article,Hierarchical and Hybrid Organizational Structures in Open-source Software Projects: A Longitudinal Study,"Despite the absence of a formal process and a central command-and-control structure, developer organization in open-source software (OSS) projects are far from being a purely random process. Prior work indicates that, over time, highly successful OSS projects develop a hybrid organizational structure that comprises a hierarchical part and a non-hierarchical part. This suggests that hierarchical organization is not necessarily a global organizing principle and that a fundamentally different principle is at play below the lowest positions in the hierarchy. Given the vast proportion of developers are in the non-hierarchical part, we seek to understand the interplay between these two fundamentally differently organized groups, how this hybrid structure evolves, and the trajectory individual developers take through these structures over the course of their participation. We conducted a longitudinal study of the full histories of 20 popular OSS projects, modeling their organizational structures as networks of developers connected by communication ties and characterizing developers' positions in terms of hierarchical (sub)structures in these networks. We observed a number of notable trends and patterns in the subject projects: (1) hierarchy is a pervasive structural feature of developer networks of OSS projects; (2) OSS projects tend to form hybrid organizational structures, consisting of a hierarchical and a non-hierarchical part; and (3) the positional trajectory of a developer starts loosely connected in the non-hierarchical part and then tightly integrate into the hierarchical part, which is associated with the acquisition of experience (tenure), in addition to coordination and coding activities. Our study (a) provides a methodological basis for further investigations of hierarchy formation, (b) suggests a number of hypotheses on prevalent organizational patterns and trends in OSS projects to be addressed in further work, and (c) may ultimately guide the governance of organizational structures.",10.1145/3569949

We start with the construction of 6 categories of leadership behaviors based on existing leadership studies. Then, we manually label leadership behaviors in 10,000 issue comments from 10 OSS projects, and extract 304 heuristic linguistic patterns which represent different types of emergent leadership behaviors in flexible and concise manners. Next, an automated algorithm is developed to merge and consolidate different pattern sets extracted from multiple projects into a final pattern ranking list, which can be applied for the automatic leadership identification.

When packages are large, they often carry maintainability quality issues. In the literature, there is a lack of empirical evidence on the specific maintainability issues that occur when packages become too large. Our study fills this gap by performing relationship analysis of package size with respect to internal maintainability characteristics (coupling, cohesion, and complexity) using package-level metrics collected from 111 open-source Java projects provided in Qualitas Corpus. Our results show significantly higher main-tainability issues in large packages as indicated by the maintainability metrics. We also report strong relationships of package size with cohesion (represented by the number of connected components in a package) and complexity (measured by the number of internal relationships in a package). Based on these strong associations with package size, we show that these cohesion and complexity metrics can be used to identify large package refactoring opportunities. Furthermore, we also discuss why some maintainability metrics (e.g., coupling metrics) may not be useful for refactoring large packages.Editor's note: Open Science material was validated by the Journal of Systems and Software Open Science Board.(c) 2023 Elsevier Inc.

Nowadays, pork floss is known to consumers as a leisure food. It is made from pork through a unique process in which the muscle fibers become flaky or granular and tangled. In this study, a deep learning-based approach is proposed to detect the quality characteristics of pork floss structure. Describe that the experiments were conducted using widely recognized brands of pork floss available in the grocery market, omitting the use of abbreviations. A total of 8000 images of eight commercially available pork flosses were collected and processed using sharpening, image gray coloring, real-time shading correction, and binarization. After the machine learning model learned the features of the pork floss, the images were labeled using a manual mask. The coupling of residual enhancement mask and region-based convolutional neural network (CRE-MRCNN) based deep learning framework was used to segment the images. The results showed that CRE-MRCNN could be used to identify the knot features and pore features of different brands of pork floss to evaluate their quality. The combined results of the models based on the sensory tests and machine vision showed that the pork floss from TC was the best, followed by YJJ, DD and HQ.

We aimed to compare the impact of early palliative care including formal concertation with oncologists on decision for an additional line of chemotherapy compared with usual oncology care. Methods This randomized prospective study enrolled adult women with metastatic breast cancer and visceral metastases with a 3rd- or 4th-line chemotherapy (CT). Patients received usual oncology care with a palliative care consultation only upon patient or oncologist request (standard group, S) or were referred to systematic palliative care consultation including a regular concertation between palliative care team and oncologists (early palliative care group, EPC). The primary endpoint was the rate of an additional CT (4th or 5th line) decision. Quality of life, symptoms, social support and satisfaction were self-evaluated at 6 and 12 months, at treatment discontinuation or 3 months after discontinuation. Results From January 2009 to November 2012, two authorized cancer centers included 98 women (EPC: 50; S: 48). Thirty-seven (77.1\\%, 95\\%CI 62.7-88\\%) patients in the EPC group had a subsequent chemotherapy prescribed and 36 (72.0\\%, 95\\%CI 57.5-83.8\\%) in the S group (p = 0.646).

+1910,Article,Innovating beyond firm boundaries: resource deployment control in open source software development,"Purpose In times of open and distributed innovation, many innovation activities that are important for firms' products and services take place beyond the boundaries of the firm and thus beyond firms' direct control. A prime example for this phenomenon is open source software (OSS) development, where multiple actors contribute to a public good, which is also integrated into company-owned software products. Despite the importance of aligning community work on the public good with own in-house development efforts, firms have limited options to directly control the OSS project or the project's outcome. This research reflects on resource deployment control, a control mode in which firms assign own developers to work for an OSS project to influence the OSS project, and tests hypotheses on individual developer levels. Design/methodology/approach This research tests the effect of perceived resource deployment control on opinion leadership by analyzing employed Linux kernel developers. Findings The findings show that developers who perceive being assigned to an OSS project to enact control also exhibit opinion leadership. This research also investigates boundary conditions such as the OSS business model a firm operates and the reputation developers assign to the developers' employer.

+1918,Article,Large-Scale Identification and Analysis of Factors Impacting Simple Bug Resolution Times in Open Source Software Repositories,"One of the most prominent issues the ever-growing open-source software community faces is the abundance of buggy code. Well-established version control systems and repository hosting services such as GitHub and Maven provide a checks-and-balances structure to minimize the amount of buggy code introduced. Although these platforms are effective in mitigating the problem, it still remains. To further the efforts toward a more effective and quicker response to bugs, we must understand the factors that affect the time it takes to fix one. We apply a custom traversal algorithm to commits made for open source repositories to determine when ``simple stupid bugs{''} were first introduced to projects and explore the factors that drive the time it takes to fix them. Using the commit history from the main development branch, we are able to identify the commit that first introduced 13 different types of simple stupid bugs in 617 of the top Java projects on GitHub. Leveraging a statistical survival model and other non-parametric statistical tests, we found that there were two main categories of categorical variables that affect a bug's life; Time Factors and Author Factors. We find that bugs are fixed quicker if they are introduced and resolved by the same developer. Further, we discuss how the day of the week and time of day a buggy code was written and fixed affects its resolution time. These findings will provide vital insight to help the open-source community mitigate the abundance of code and can be used in future research to aid in bug-finding programs.",10.3390/app13053150

EBA involves the use of psychometric instruments to gather data that can inform clinical decision-making, inform policymakers, and serve as a basis for research and quality management. Despite its potential, EBA is often hindered by barriers such as workload and cost, leading to its underutilization. Regarding low- and middle-income countries (LMIC), the implementation of EBA is recognized as a key strategy to address and close the prevalent mental health treatment gap.To simplify the application of EBA including in LMIC, an international team of researchers and practitioners from Tanzania, Kosovo, Chile, and Switzerland developed the Mental Health Information Reporting Assistant (MHIRA). MHIRA is an open-source electronic health record that streamlines EBA by digitising psychometric instruments and organising patient data in a user-friendly manner. It provides immediate and convenient reports to inform clinical decision-making.The current article provides a comprehensive overview of the features and technical details of MHIRA, as well as insights from four implementation scenarios. The experience gained during the implementations as well as the user-feedback suggests that MHIRA has the potential to be successfully implemented in a variety of clinical contexts and simplify the use of EBA. However, further research is necessary to establish its potential to sustainably transform healthcare services and impact patient outcomes.In conclusion, MHIRA represents an important step in promoting the widespread adoption of EBA in mental health. It offers a promising solution to the barriers that have limited the use of EBA in the past and holds the potential to improve patient outcomes and support the ongoing efforts to address gaps in mental health care.",10.1186/s12888-023-05201-0
+1934,Article,Mission-critical open-source software adoption model validation using Partial Least Square - Structural Equation Modeling,"This paper aims to validate the mission-critical OSS (open-source software) model acceptance process using a third-order formative-formative measuring model. A two-stage formative-formative model was used for partial least square analysis. It includes eight primary mission-critical OSS adoption constructs and three second-order (technological, organizational, and environmental). Although nomological validity was affirmed, the empirical findings show the absence of multicollinearity. This study will give organizations in critical industries enough information to understand the importance and weight of each component/factor of the mission-critical OSS adoption model. The coefficient of determination R-2 exceeds the minimum threshold (0.750), and all the hypotheses are significant. This study also contributed to the existing literature by identifying those factors that influence mission-critical OSS adoption, allowing firms in critical sectors to better understand their mission-critical OSS adoption issues. Cross-cultural validation across a broad community is proposed to increase the validity and generalization of the sample scales.",10.1002/smr.2514
+1935,Article,NUMERICAL ANALYSIS AND DIFFUSER VANE SHAPE OPTIMIZATION OF A RADIAL COMPRESSOR WITH THE OPEN-SOURCE SOFTWARE SU2,"In recent years, the usage of open -source computational fluid dynamics tools is on a rise both in industry and academia. SU2 is one of these open -source tools. Unlike other open -source alternatives, SU2 is equipped with boundary condition types, solvers and methods that are especially developed for the analysis and design of turbomachinery. The aim of this work is to explore and investigate the capabilities of SU2 in the prediction of performance parameters of radial compressors. Two different single stage shrouded compressor geometries, one with a vaneless diffuser and the other with a vaned diffuser have been investigated with steady state CFD. The compressors were designed by MAN Energy Solutions Schweiz AG. Computational results with SU2 showed a satisfactory agreement with both the experimental data and reference CFD solutions obtained with Fidelity Flow, which is formerly known as Numeca Fine TURBO. Only at the relatively higher mass flow rates the difference between references and SU2 were higher compared to other operating points. After performance parameters were successfully calculated with SU2, the optimization tools that come with SU2 were also used. A 2D adjoint optimization study on the vane of the vaned diffuser was carried out. The study was carried out at a single operating point that is close to choke conditions. The loss generated by the large separated flow region at the suction side of the diffuser vane was reduced by 0.55 \\% in the optimized geometry using minimal modifications on the existing vane geometry to keep the performance of the compressor intact at other operating points. However, the resulting modification increased the total pressure loss by 0.86 \\% at one of the design operating points. This performance penalty could be due to the discontinuity in the vane geometry generated by the optimizer. Overall, the study shows that SU2 has the basic numerical schemes and models that are required for the analysis of radial turbomachinery flows and geometry optimization.",10.47480/isibted.1391729

The communities responsible for building this cyberinfrastructure require maintenance and moderation, which is often supported by volunteer efforts. Moderation, as a non-technical form of labor, is a necessary but often overlooked task that maintainers undertake to sustain the community around an OSS project. This study examines the various structures and norms that support community moderation, describes the strategies moderators use to mitigate conflicts, and assesses how bots can play a role in assisting these processes. We interviewed 14 practitioners to uncover existing moderation practices and ways that automation can provide assistance. Our main contributions include a characterization of moderated content in OSS projects, moderation techniques, as well as perceptions of and recommendations for improving the automation of moderation tasks. We hope that these findings will inform the implementation of more effective moderation practices in open source communities.",10.1145/3610092
+1938,Article,Novel Multi-Perspective Usability Evaluation Framework for Selection of Open Source Software Based on BWM and Group VIKOR Techniques,"Increasing demand for open-source software (OSS) has raised the value of efficient selection in terms of quality; usability is an essential quality factor that significantly affects system acceptability and sustainability. Most large and complex software packages partitioned across multiple portals and involve many users - each with their role in the software package; those users have different perspectives on the software package, defined by their knowledge, responsibilities, and commitments. Thus, a multi-perspective approach has been used in usability evaluation to overcome the challenge of inconsistency between users' perspectives; the inconsistency challenge would lead to an ill-advised decision on the selection of a suitable OSS. This study aimed to assist the public and private organizations in evaluating and selecting the most suitable OSS. The evaluation of the OSS software packages to choose the best one is a challenging task owing to (a) multiple evaluation criteria, (b) criteria importance, and (c) data variation; thus, it is considered a sophisticated multi-criteria decision making (MCDM) problem; moreover, the multi-perspective usability evaluation framework for OSS selection lacks in the current literature. Hence, this study proposes a novel multi-perspective usability evaluation framework for the selection of OSS based on the multi-criteria analysis. Integration of best-worst method (BWM) and VIKOR MCDM techniques has been used for weighting and ranking OSS alternatives. BWM is utilized for weighting of evaluation criteria, whereas VIKOR is applied to rank OSS-LMS alternatives. Individual and group decision-making contexts, and the internal and external groups aggregation were used to demonstrate the efficiency of the proposed framework. A well-organized algorithmic procedure is presented in detail, and a case study was examined to illustrate the validity and feasibility of the proposed framework. The results demonstrated that BWM and VIKOR integration works effectively to solve the OSS software package benchmarking/selection problems. Furthermore, the ranks of OSS software packages obtained from the VIKOR internal and external group decision making were similar; the best OSS-LMS based on the two ways was `Moodle' software package. Among the scores of groups in the objective validation, significant differences were identified; this indicated that the ranking results of internal and external VIKOR group decision making were valid, which pointed to the validation of the framework.",10.1142/S0219622021500139

+1943,Article,Off to a Good Start: Dynamic Contribution Patterns and Technical Success in an OSS Newcomer's Early Career,"Attracting and retaining newcomers are critical aspects for OSS projects, as such projects rely on newcomers' sustainable contributions. Considerable effort has been made to help newcomers by identifying and overcoming the barriers during the onboarding process. However, most newcomers eventually fail and drop out of their projects even after successful onboarding. Meanwhile, it has been long known that individuals' early career stages profoundly impact their long-term career success. However, newcomers' early careers are less investigated in SE research. In this paper, we sought to develop an empirical understanding of the relationships between newcomers' dynamic contribution patterns in their early careers and their technical success. To achieve this goal, we compiled a dataset of newcomers' contribution data from 54 large OSS projects under three different ecosystems and analyzed it with time series analysis and other statistical analysis techniques. Our analyses yield rich findings. The correlations between several contribution patterns and technical success were identified. In general, being consistent and persistent in newcomers' early careers is positively associated with their technical success. While these correlations generally hold in all three ecosystems, we observed some differences in detailed contribution patterns correlated with technical success across ecosystems. In addition, we performed a case study to investigate whether another type of contributions, i.e., documentation contribution, could potentially have positive correlations with newcomers' technical success. We discussed the implications and summarized practical recommendations to OSS newcomers. The insights gained from this work demonstrated the necessity of extending the focus of research and practice to newcomers' early careers and hence shed light on future research in this direction.",10.1109/TSE.2022.3156071
+1947,InProceedings,Open Source Software Onboarding as a University Course: An Experience Report,"Without newcomers, open source software (OSS) projects are hardly sustainable. Yet, newcomers face a steep learning curve during OSS onboarding in which they must overcome a multitude of technical, social, and knowledge barriers. To ease the onboarding process, OSS communities are utilizing mentoring, task recommendation (e.g., ``good first issues{''}), and engagement programs (e.g., Google Summer of Code). However, newcomers must first cultivate their motivation for OSS contribution and learn the necessary preliminaries before they can take advantage of these mechanisms. We believe this gap can be filled by a dedicated, practice-oriented OSS onboarding course. In this paper, we present our experience of teaching an OSS onboarding course at Peking University. The course contains a series of lectures, labs, and invited talks to prepare students with the required skills and motivate them to contribute to OSS. In addition, students are required to complete a semester-long course project in which they plan and make actual contributions to OSS projects. They can either contribute to some recommended OSS projects with dedicated mentors, or contribute to any OSS project they prefer. Finally, 16 out of the 19 enrolled students have successfully contributed to OSS projects, and five have retained. However, the onboarding trajectories, final contributions, and retention outcomes differ vastly between the two groups of students with different course project choices, yielding lessons for software engineering education.",10.1109/ICSE-SEET58685.2023.00037
+1951,InProceedings,Open Source Software Tools for Data Management and Deep Model Training Automation,"Designing and optimizing deep models require managing large datasets and conducting carefully designed controlled experiments that depend on large sets of hyper-parameters and problem dependent software/data configurations. These experiments are executed by training the model under observation with varying configurations. Since executing a typical training run can take days even on proven acceleration fabrics such as Graphics Processing Units (GPU), properly managing training data, avoiding human error in configuration preparations and securing the repeatability of the experiments are of utmost importance. In this paper, we present two open source software tools that aim to achieve these goals, namely, a Dataset Manager (DatumAid) tool and a Training Automation Manager (OrchesTrain) tool. DatumAid is a software tool that integrates with Computer Vision Annotation Tool (CVAT) to facilitate the management of annotated datasets. By adding additional functionality, DatumAid allows users to filter labeled data, manipulate datasets, and export datasets for training purposes. The tool adopts a simple code structure while providing flexibility to users through configuration files. OrchesTrain aims to automate model training process by facilitating rapid preparation and training of models in the desired style for the intended tasks. Users can seamlessly integrate their models prepared in the PyTorch library into the system and leverage the full capabilities of OrchesTrain. It enables the simultaneous or separate usage of Wandb, MLflow, and TensorBoard loggers. To ensure reproducibility of the conducted experiments, all configurations and codes are saved to the selected logger in an appropriate structure within a YAML file along with the serialized model files.

This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software. Design/methodology/approach A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76\\%. Findings The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff. Research limitations/implications This study is geographically limited to the university libraries in Islamabad. Practical implications This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries.

+1958,Article,"Optimization of Revision Hip Arthroplasty Workflow by Means of Detailed Pre-Surgical Planning Using Computed Tomography Data, Open-Source Software and Three-Dimensional-Printed Models","Background. In revision hip arthroplasty (RHA), establishing the center of rotation (COR) can be technically challenging due to the acetabular bone destruction that is usually present, particularly in severe cases such as Paprosky type II and III defects. The aim of this study was to demonstrate the use of open-source medical image reconstruction software and low-cost 3D anatomical models in pre-surgical planning of RHA. Methods. A total of 10 patients, underwent RHA and were included in the study. Computed tomography (CT) scans were performed for all cases, before surgery and approximately 1 week after the procedure. The reconstruction of CT data, 3D virtual planning of the COR and positioning of acetabular cups, including their inclination and anteversion angles, was carried out using the free open source software platform 3D Slicer. In addition, anatomical models of the pelvis were built on a desktop 3D printer from polylactic acid (PLA). Preoperative and postoperative reconstructed imaging data were compared for each patient, and the position of the acetabular cups as well as the COR were evaluated for each case. Results. Analysis of the pre- and post-op center of rotation position data indicated statistically insignificant differences for the location of the COR on the X-axis (1.5 mm, t = 0.5741, p = 0.5868) with a fairly strong correlation of the results (r = -0.672, p = 0.0982), whilst for the location of the COR in the Y and Z-axes, there was statistical dependence (Y axis, 4.7 mm, t = 3.168 and p = 0.0194; Z axis, 1.9 mm, t = 1.887 and p = 0.1081). A strong correlation for both axes was also observed (Y and Z) (Y-axis, r = 0.9438 and p = 0.0014; Z-axis, r = 0.8829 and p = 0.0084). Analysis of inclination angle values showed a statistically insignificant difference between mean values (3.9 degrees, t = 1.111, p = 0.3092) and a moderate correlation was found between mean values (r = -0.4042, p = 0.3685). Analysis of the anteversion angle showed a statistically insignificant difference between mean values (1.9 degrees, t = 0.8671, p = 0.4192), while a moderate correlation between mean values was found (r = -0.4782, p = 0.2777). Conclusions. Three-dimensional reconstruction software, together with low-cost anatomical models, are very effective tools for pre-surgical planning, which have great potential use in orthopedic surgery, particularly RHA. In up and in- and up and out-type defects, it is essential to establish a new COR and to identify three support points within the revision acetabulum in order to correctly position acetabular cups.",10.3390/diagnostics13152516

+1960,Article,Perceptions of open-source software developers on collaborations: An interview and survey study,"With the emergence of social coding platforms, collaboration has become a key and dynamic aspect to the success of software projects. In such platforms, developers have to collaborate and deal with issues of collaboration in open-source software development. Although collaboration is challenging, collaborative development produces better software systems than any developer could produce alone. Several approaches have investigated collaboration challenges, for instance, by proposing or evaluating models and tools to support collaborative work. Despite the undeniable importance of the existing efforts in this direction, there are few works on collaboration from perspectives of developers. In this work, we aim to investigate the perceptions of open-source software developers on collaborations, such as motivations, techniques, and tools to support global, productive, and collaborative development. Following an ad hoc literature review, an exploratory interview study with 12 open-source software developers from GitHub, our novel approach for this problem also relies on an extensive survey with 121 developers to confirm or refute the interview results. We found different collaborative contributions, such as managing change requests. Besides, we observed that most collaborators prefer to collaborate with the core team instead of their peers. We also found that most collaboration happens in software development (60\\%) and maintenance (47\\%) tasks. Furthermore, despite personal preferences to work independently, developers still consider collaborating with others in specific task categories, for instance, software development. Finally, developers also expressed the importance of the social coding platforms, such as GitHub, to support maintainers, and contributors in making decisions and developing tasks of the projects. Therefore, these findings may help project leaders optimize the collaborations among developers and reduce entry barriers. Moreover, these findings may support the project collaborators in understanding the collaboration process and engaging others in the project.",10.1002/smr.2393

However, as the provided open-source solutions are managed in all aspects by their designers/engineers, they lack professional evaluation of their security level. The absence of comprehensive security assessment as well as a consolidated and ubiquitous roadmap for vulnerability patching and security hardening, makes open-source solution a risk for widespread enterprise use. This paper introduces a security assurance approach which addresses open-source hardware and software shortcoming in an end-to-end manner, by providing a logical decomposition of any such module into four distinct component layers: device, network, application and cognitive. This allows highly focused security assessment, taking into consideration the specific characteristics of each layer. In addition, the paper provides an approach on how open-source solution security can be improved, through decomposition, layered vulnerability mitigation and specialized security hardening techniques.

State-of-the-art characterization of sample materials related to these fields, deploying high-end instrumentation, allows for gathering large quantities of molecular composition data. One established technological platform is ultrahigh-resolution mass spectrometry, e.g., Fourier-transform mass spectrometry (FT-MS). However, the huge amounts of data acquired in FT-MS often result in tedious data treatment and visualization. FT-MS analysis of complex matrices can easily lead to single mass spectra with more than 10,000 attributed unique molecular formulas. Sophisticated software solutions to conduct these treatment and visualization attempts from commercial and noncommercial origins exist. However, existing applications have distinct drawbacks, such as focusing on only one type of graphic representation, being unable to handle large data sets, or not being publicly available. In this respect, we developed a software, within the international complex matrices molecular characterization joint lab (IC2MC), named ``python tools for complex matrices molecular characterization{''} (PyC2MC). This piece of software will be open-source and free to use. PyC2MC is written under python 3.9.7 and relies on well-known libraries such as pandas, NumPy, or SciPy. It is provided with a graphical user interface developed under PyQt5. The two options for execution, (1) a user-friendly route with a prepacked executable file or (2) running the main python script through a Python interpreter, ensure a high applicability but also an open characteristic for further development by the community.

The transformation of the measured reflection coefficient to complex permittivity is performed based on three different methods. The software library contains the dielectric spectra of common reference liquids, which can be used to transform the reflection coefficient into the dielectric spectra. Several Python routines that are commonly employed (e.g., SciPy and NumPy) in the field of science and engineering are required only so that the users can alter the software structure depending on their needs. The modeling algorithm exploits the Markov Chain Monte Carlo method for the data regression. The discrete relaxation models can be built by a proper combination of well-known relaxation models. In addition to these models, electrode polarization, a typical measurement artifact for interpreting dielectric spectra, can be incorporated into the modeling algorithm. A continuous relaxation model, which solves the Fredholm integral equation of the first kind (a mathematically ill-posed problem), is also included. This open-source software enables users to freely adjust the physical parameters to obtain physical insight into their materials under test and will be consistently updated for more accurate measurement and interpretation of dielectric spectra in an automated manner. This work describes the theoretical and mathematical background of the software, lays out the workflow, and validates the software functionality based on both synthetic and empirical data included in the software.

The obtained dielectric spectra can be useful for understanding the relaxation processes in an arbitrary fluid. Solution method: The reflection coefficient data is obtained as a text format from a Vector Network Analyzer (VNA). This text data is parsed into a Numpy array. Three different modules (Stuchly, Marsland, and Komarov) can be used to transform the parsed reflection coefficient data into complex permittivity as a function of the measurement frequency. The resultant dielectric spectra can be dissected and interpreted by fitting either discrete relaxation model(s) based on the Markov Chain Monte Carlo algorithm or a continuous relaxation model by applying the Zasetsky-Buchner method.

+1968,Article,RESILIENCE IN THE OPEN SOURCE SOFTWARE COMMUNITY: HOW PANDEMIC AND UNEMPLOYMENT SHOCKS INFLUENCE CONTRIBUTIONS TO OTHERS' AND ONE'S OWN PROJECTS,"Contributions by individual open source software (OSS) community members are the lifeblood of the OSS projects that power today's digital economy and are important for the very survival of such communities. Individual contributions by OSS community members to others' projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others' projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others' projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members' contributions to others' projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members' contributions to others' projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings' implications for OSS community resilience.",10.25300/MISQ/2022/17256
+1970,Article,Reconstructing 3D ocean subsurface salinity (OSS) from T-S mapping via a data-driven deep learning model,"Despite the increasing volume of oceanographic data, the available ocean salinity data remains patently insufficient which limits studying ocean dynamics, climate change and the calculation of salinity-related ocean elements. Considering that traditional salinity reconstruction methods often suffer from various factors such as additional constraints, priori physical assumptions and large of specific regression coefficients, a generative adversarial networks (GANs) based deep learning (DL) framework is proposed to directly construct a near real-time, high-resolution daily three-dimensional ocean subsurface salinity (3D OSS) dataset from a data driven perspective in this study. Four models with different structural combinations are designed in the China's marginal seas. Experimental results demonstrate that the models can successfully reconstruct the high-precision and high-resolution 3D OSS on a daily scale in 12 depth levels (from 2 m to 200 m). The asymmetric inception3DGAN model with all enhanced structures has the highest accuracy, the average root-mean-squared error (RMSE) is 0.135psu, the average coefficient of determination (R2) is 0.5641 and the percent bias is 0.436\\%. Comparing with model without enhanced structures, the average RMSE is decreased by 22.41\\% when adding all the enhancement structures. Besides, temporal and spatial error analysis are also conducted to evaluate the models' performance from different aspects. Finally, the model results are used to analyze common ocean elements, such as water mass properties, dynamic fields and geostrophic velocity fields, demonstrating that the 3D OSS dataset construction approach proposed in this study not only provides some new insights into ocean observations, but also has high application values.",10.1016/j.ocemod.2023.102232
+1972,Article,Release conventions of open-source software: An exploratory study,"Software engineering (SE) methodologies are widely used in both academia and industry to manage the software development life cycle. A number of studies of SE methodologies involve interviewing stakeholders to explore the real-world practice. Although these interview-based studies provide us with a user's perspective of an organization's practice, they do not describe the concrete summary of releases in open-source social coding platforms. In particular, no existing studies investigated how releases are evolved in open-source coding platforms, which assist release planners to a large extent. This study explores software development patterns followed in open-source projects to see the overall management's reflection on software release decisions rather than concentrating on a particular methodology. Our experiments on 51 software origins (with 1777k revisions and 12k releases) from the Software Heritage Graph Dataset (SWHGD) and their GitHub project boards (with 23k cards) reveal reasonably active project management with phase simplicity can release software versions more frequently and can follow the small release conventions of Extreme Programming. Additionally, the study also reveals that a combination of development and management activities can be applied to predict the possible number of software releases in a month (rho< 0:05).",10.1002/smr.2499
+1973,Article,Reset and restoration. The looming conservative turn of management theory: An extension of Foss et al.,"This article is a reply to Foss et al.'s (2022) contribution to the special issue of the Scandinavian Journal of Management on The Great Reset of management and organization theory. In their article, the authors make a strong case that ``reset thinking{''} geared towards a more ``sustainable{''} redesign of the global economy promotes extensive state interventionism and cronyism capitalism, and therefore reject the idea of a need for ``a funda-mental rethink of existing management theory{''}. Whereas I do agree with the authors on most points, I am less convinced that ``existing management theory{''} will suffice to address the problem of ``reset thinking{''}. In this article, I demonstrate that the economy-bias of existing theories is a gateway for ``reset thinking{''} geared towards an allegedly necessary re-/socialisation of management and organisation. A research agenda on cronyism must therefore be complemented by one on privilege and hierarchy not only as undesirable side-effects of cronyism, but also as desired outcomes of advocacy for specific minorities or missions. As self-identifications with group interests or calls for missions have become popular in management theory, I conclude that this new appetite for privilege might undermine not only the higher ideals of many management theorists, but also the foundations of modern society.",10.1016/j.scaman.2023.101278
+1977,Article,Risk Factors and Practices for the Development of Open Source Software From Developers' Perspective,"Open source software (OSS) has achieved popularity, however there are various software product quality problems, security issues and certain challenges confronting the OSS growth that need to be identified and addressed. The main focus of this research is to identify the risk factors associated with open-source software and the practices for those risks which will help software development companies and individuals to mitigate the risks. A systematic literature review (SLR) is employed for the identification of potential risk factors in OSS whereas questionnaire survey is used to validate the findings of the SLR from the relevant expert community. In the second round another SLR is carried out to identify the practices for softening the effect of risk-factors in OSS development. A total of 14 risk factors from the developers' perspective are identified via SLR in OSS. Amid the risk factors identified bugs, insufficient product documentation, and lack of communication and coordination among developers are considered the most important Further, we performed a secondary SLR to identify the practices for mitigating the effects of the risk factors in OSS. Therefore, a total of 31 practices for mitigating and addressing the risk factors in OSS were identified. In this work, we identified 14 risk factors and 31 practices for mitigating the critical risk factors, through SLR for adapting OSS development from developers' perspectives. We argue that focusing on the identified risk factors would minimize the risks associated with OSS. We also recommend that OSS developers should diligently consider all the risk factors that have been identified in the study for increased software productivity and distribution of reliable and robust source code.",10.1109/ACCESS.2023.3267048

From large technology companies to startups, companies are participating in the OSS ecosystem by open-sourcing their technology, sponsoring projects through funding or paid developer time. However, our understanding of the OSS ecosystem is rooted in the ``old world{''} model where individual contributors sustain OSS projects. In this work, we create a more comprehensive understanding of the hybrid OSS landscape by investigating what motivates companies to contribute and how they contribute to OSS. We conducted interviews with 20 participants who have different roles (e.g., CEO, OSPO Lead, Ecosystem Strategist) at 17 different companies of different sizes from large companies (e.g. Microsoft, RedHat, Google, Spotify) to startups. Data from semi-structured interviews reveal that company motivations can be categorized into four levels (Founders' Vision, Reputation, Business Advantage, and Reciprocity) and companies participate through different mechanisms (e.g., Developers' Time, Mentoring Time, Advocacy \\& Promotion Time), each of which tie to the different types of motivations. We hope our findings nudge more companies to participate in the OSS ecosystem, helping make it robust, diverse, and sustainable.",10.1109/ICSE48619.2023.00218
+1982,Article,Scrutinizing the available SRGMs in the backdrop of open-source software while offering a way-out,"Software reliability growth models (SRGMs) are more often appropriate for assessing the quality of the closed-source projects including their development lifecycles because they are dependent on underlying assumptions. It is debatable whether they should be used in open-source software (OSS) initiatives. There are studies examining the SRGMs' applicability in the OSS setting, but their scope is constrained by the models and projects they take into account, which could result in inconsistent findings. In this paper, the available SRGMs in the backdrop of OSS have been scrutinized and limitations have been identified. To address these limitations, a modification to the SRGMs using fuzzy neural networks (FNNs) has been proposed. In this paper, various SRGMs have been reviewed and sharp distinction among the same has been made, taking their respective failure intensity and mean value function under consideration. Through the failure intensity of software, it becomes a cakewalk to identify and predict the faults even before they actually arise and necessary and timely action may be initiated. After duly considering the review and contrast between the factors, a FNN model has been suggested for determination of software reliability differing with values of failure intensity and mean value function. First software failure data from a number of open-source software (OSS) projects have been gathered as part of the methodology used to modify traditional SRGMs. The proposed model gives out a high reliability rate and a low failure intensity. The most important factor is that it caters for the faults that are current and are being faced by the users on day to basis currently. It was found that the proposed model has a high success rate with the value of 82.6950937\\% which is considered as a successful result for software. The suggested FNN model may have a potential impact on the field of software reliability since FNN can handle the ambiguity and imprecision in the software failure data that are typical in open-source projects.",10.1007/s00500-023-08761-1

+1984,Article,Seismo-VLAB: An Open-Source Software for Soil-Structure Interaction Analyses,"In the fields of structural and geotechnical engineering, improving the understanding of soil-structure interaction (SSI) effects is critical for earthquake-resistant design. Engineers and practitioners often resort to finite element (FE) software to advance this objective. Unfortunately, the availability of software equipped with boundary representation for absorbing scattered waves and ensuring consistent input ground motion prescriptions, which is necessary for accurately representing SSI effects, is currently limited. To address such limitations, the authors developed Seismo-VLAB (SVL v1.0-stable) an open-source software designed to perform SSI simulations. The methodology considers the integration of advanced techniques, including the domain decomposition method (DDM), perfectly matched layers (PMLs), and domain reduction method (DRM), in addition to parallel computing capabilities to accelerate the solution of large-scale problems. In this work, the authors provide a detailed description of the implementation for addressing SSI modeling, validate some of the SVL's features needed for such purpose, and demonstrate that the coupled DRM-PML technique is a necessary condition for accurately solving SSI problems. It is expected that SVL provides a significant contribution to the SSI research community, offering a self-contained and versatile alternative. The software's practical application in analyzing SSI and directionality effects on 3D structures under seismic loading demonstrates its capability to model real-world earthquake responses in structural engineering.",10.3390/math11214530
+1985,Article,SimpleMind: An open-source software environment that adds thinking to deep neural networks,"Deep neural networks (DNNs) detect patterns in data and have shown versatility and strong performance in many computer vision applications. However, DNNs alone are susceptible to obvious mistakes that violate simple, common sense concepts and are limited in their ability to use explicit knowledge to guide their search and decision making. While overall DNN performance metrics may be good, these obvious errors, coupled with a lack of explainability, have prevented widespread adoption for crucial tasks such as medical image analysis. The purpose of this paper is to introduce SimpleMind, an open-source software environment for Cognitive AI focused on medical image understanding. It allows creation of a knowledge base that describes expected characteristics and relationships between image objects in an intuitive human-readable form. The knowledge base can then be applied to an input image to recognize and understand its content. SimpleMind brings thinking to DNNs by: (1) providing methods for reasoning with the knowledge base about image content, such as spatial inferencing and conditional reasoning to check DNN outputs; (2) applying process knowledge, in the form of general-purpose software agents, that are dynamically chained together to accomplish image preprocessing, DNN prediction, and result post-processing, and (3) performing automatic co-optimization of all knowledge base parameters to adapt agents to specific problems. SimpleMind enables reasoning on multiple detected objects to ensure consistency, providing cross-checking between DNN outputs. This machine reasoning improves the reliability and trustworthiness of DNNs through an interpretable model and explainable decisions. Proof-of-principle example applications are provided that demonstrate how SimpleMind supports and improves deep neural networks by embedding them within a Cognitive AI environment.",10.1371/journal.pone.0283587
+1986,InProceedings,Skill Recommendation for New Contributors in Open-Source Software,"Selecting an appropriate task is challenging for newcomers to Open Source Software (OSS) projects. Therefore, researchers and OSS projects have proposed strategies to label tasks (a.k.a. issues). Several approaches relying on machine learning techniques, historical information, and textual analysis have been submitted. However, the results vary, and these approaches are still far from mainstream adoption, possibly because of a lack of good predictors. Inspired by previous research, we advocate that the prediction models might benefit from leveraging social metrics. In this research, we investigate how to assist the new contributors in finding a task when onboarding a new project. To achieve our goal, we predict the skills needed to solve an open issue by labeling them with the categories of APIs declared in the source code (API-domain labels) that should be updated or implemented. Starting from a case study using one project and an empirical experiment, we found the API-domain labels were relevant to select an issue for a contribution. In the sequence, we investigated employing interviews and a survey of what strategies maintainers the strategies believe the communities have to adopt to assist the new contributors in finding a task. We also studied how maintainers think about new contributors' strategies to pick a task. We found maintainers, frequent contributors, and new contributors diverge about the importance of the communities and new contributors' strategies. The ongoing research works in three directions: 1) generalization of the approach, 2) Use of conversation data metrics for predictions, 3) Demonstration of the approach, and 4) Matching contributors and tasks skills. By addressing the lack of knowledge about the skills in tasks, we hope to assist new contributors in picking tasks with more confidence.",10.1109/ICSE-Companion58688.2023.00084

This work proposes a general taxonomy for attacks on opensource supply chains, independent of specific programming languages or ecosystems, and covering all supply chain stages from code contributions to package distribution.

Employing a ``microhistories{''} methodology, we document how actors in the free/open-source movement took steps that enabled an alternate technological niche to form, gain momentum and even-tually infiltrate the extant regime. Our account delineates the key role that actors play in shaping the identity of a niche, amplifying its presence, and finally mainstreaming it. We observe a heterogenous response by incumbents to the emergent niche and highlight the sustained coexistence of a niche and regime as a distinct form of techno-logical transition. Finally, we demonstrate the significant impact that a niche can have, spanning beyond the targeted regime, and becoming part of the landscape. Our insights highlight how tracing the processes involved in the emergence and development of a niche can provide a prospective and generative understanding of technological transition, thereby contributing to and complementing the extant SNM and MLP literatures.",10.1016/j.respol.2022.104672

Design/methodology/approach This study focuses on dependencies using three network metrics - degree centrality, betweenness centrality and closeness centrality - in developer and module networks. A longitudinal analysis from the projects hosted at Sourceforge.net is conducted to examine the effects of social and technical networks on the success of OSS projects. To address our research questions, we have constructed research models to investigate the social network effects in developer networks, the technical network effects in module networks, and the social-technical network effects in both types of networks. Findings The results reveal nonlinear relationships between degree centrality in both social and technical networks and OSS success, highlighting the importance of a moderate level of degree centrality in team structure and software architecture. Meanwhile, a moderate level of betweenness centrality and a lower level of closeness centrality between developers lead to a higher chance of OSS project success.

+1994,Article,Software reliability model for open-source software that considers the number of finite faults and dependent faults,"Software has become a vital factor in the fourth industrial revolution. Owing to the increase in demand for software products in various fields (big data, artificial intelligence, the Internet of Things, etc.), the software industry has expanded more than ever before. Therefore, software reliability has become very important, and efforts are being made to increase it. One of these efforts is the development of software reliability models (SRMs). SRMs have been studied for a long time as a model that predicts software reliability by using the number of software faults. Software failures can occur for several reasons, including independent software faults such as code errors and software hangs, as well as dependent cases where code errors lead to other software faults. Recently, due to the diversity of software operating environments, software faults are more likely to occur in a dependent manner, and, for this reason, they are likely to increase rapidly from the beginning and progress slowly to the maximum number thereafter. In addition, many large companies have focused on open-source software (OSS) development, and OSS is being developed by many users. In this study, we propose a new SRM that considers the number of finite faults and dependent faults, and examine the goodness-of-fit of a new SRM and other existing non-homogeneous Poisson process models based on the OSS datasets. Through numerical examples, the proposed model demonstrated a significantly better goodness-of-fit when compared to other existing models, and it also exhibited better results on the newly proposed integrated criteria.",10.3934/mbe.2023524

+1998,Article,The Cilialyzer - A freely available open-source software for the analysis of mucociliary activity in respiratory cells,"Background and Objective: Primary ciliary dyskinesia (PCD) is a rare genetic disorder causing a defective ciliary structure, which predominantly leads to an impaired mucociliary clearance and associated airway disease. As there is currently no single diagnostic gold standard test, PCD is diagnosed by a combination of several methods comprising genetic testing and the examination of the ciliary structure and function. Among the approved diagnostic methods, only high-speed video microscopy (HSVM) allows to directly observe the ciliary motion and therefore, to directly assess ciliary function. In the present work, we present our recently developed freely available open-source software - termed ``Cilialyzer{''}, which has been specifically designed to support and facilitate the analysis of the mucociliary activity in respiratory epithelial cells captured by high-speed video microscopy.Methods: In its current state, the Cilialyzer software enables clinical PCD analysts to load, preprocess and replay recorded image sequences as well as videos with a feature-rich replaying module facilitating the commonly performed qualitative visual assessment of ciliary function (including the assessment of the ciliary beat pattern). The image processing methods made accessible through an intuitive user interface allow clinical specialists to comfortably compute the ciliary beating frequency (CBF), the activity map and the ``frequency correlation length{''} - an observable getting newly introduced. Furthermore, the Cilialyzer contains a simple-to-use particle tracking interface to determine the mucociliary transport speed.Results: Cilialyzer is fully written in the Python programming language and freely available under the terms of the MIT license. The proper functioning of the computational analysis methods constituting the Cilialyzer software is demonstrated by using simulated and representative sample data from clinical practice. Additionally, the software was used to analyze high-speed videos showing samples obtained from healthy controls and genetically confirmed PCD cases (DNAI1 and DNAH11 mutations) to show its clinical applicability.Conclusions: Cilialyzer serves as a useful clinical tool for PCD analysts and provides new quantitative information awaiting to be clinically evaluated using cohorts of PCD. As Cilialyzer is freely available under the terms of a permissive open-source license, it serves as a ground frame for further development of computational methods aiming at the quantification and automation of the analysis of mucociliary activity captured by HSVM.",10.1016/j.cmpb.2023.107744
+1999,Article,The Nodes Influence Maximization in Open Source Software Community Based on Probability Propagation Model,"It is of great significance to effectively and quickly identify the most influential users in the open source software community, which can be represented by a complex network. Traditional methods of measuring node influence only consider some topology characteristics of the network, so the results are one-sided. Because there are different interactive behaviors among users in the community, it is necessary to mine more interaction information, so as to give a more comprehensive measure of node influence. In view of this, this paper proposes a method to maximize the node influence of open source software community based on a probability propagation model. Firstly, according to the relationship of users and their interactive records on projects, this paper quantifies the feedback of users on the project from three aspects (i.e. approve, save and modify) and establishes a new probability propagation model between users. Secondly, this paper proposes an algorithm(SIUF) to evaluate users' influence in the open source software community based on the probability propagation model. The algorithm fully considers the interaction behavior of users in the community. In the first stage, the user's own activity is taken as the initial ranking. In the second stage, the influence of neighbor nodes is taken into account, and the SIUF value of nodes is accumulated while the rich club effect is weakened. Finally, the proposed theory and method are applied to GitHub, a typical open source software community, and the correctness and effectiveness of this method are verified from influence spread and speed.",10.1109/TNSE.2023.3247485

However, there is often a high turnover among contributors (in some projects as high as 80\\%). The survivability of contributors is influenced by various factors, including their demographics. Research on contributors' survivability must, therefore, consider diversity factors. This study longitudinally analyzed the impact of demographic attributes on survivability in the Flutter community through the lens of gender, region, and compensation. The preliminary analysis reveals that affiliated or Western contributors have a higher survival probability than volunteer or Non-Western contributors. However, no significant difference was found in the survival probability between men and women.",10.1145/3611643.3617848
+1006,Article,The Synthetic Collagen-Binding Peptide NIPEP-OSS Delays Mouse Myeloma Progression,"Multiple myeloma (MM) is the second most common hematological malignancy. It is a clonal B-cell disorder characterized by the proliferation of malignant plasma cells in the bone marrow, the presence of monoclonal serum immunoglobulin, and osteolytic lesions. An increasing amount of evidence shows that the interactions of MM cells and the bone microenvironment play a significant role, suggesting that these interactions may be good targets for therapy. The osteopontin-derived collagen-binding motif-bearing peptide NIPEP-OSS stimulates biomineralization and enhances bone remodeling dynamics. Due to its unique targeted osteogenic activity with a broad safety margin, we evaluated the potential of NIPEP-OSS for anti-myeloma activity using MM bone disease (MMBD) animal models. In a 5TGM1-engrafted NSG model, the survival rates of the control and treated groups were significantly different (p = 0.0014), with median survival times of 45 and 57 days, respectively. The bioluminescence analyses showed that myeloma slowly developed in the treated mice compared to the control mice in both models. NIPEP-OSS enhanced bone formation by increasing biomineralization in the bone. We also tested NIPEP-OSS in a well-established 5TGM1-engrafted C57BL/KaLwRij model. Similar to the previous model, the median survival times of the control and treated groups were significantly different (p = 0.0057), with 46 and 63 days, respectively. In comparison with the control, an increase in p1NP was found in the treated mice. We concluded that NIPEP-OSS delays mouse myeloma progression via bone formation in MMBD mouse models.",10.3390/cancers15092473

However, users often lack the contribution motivation. The purpose of this research is to examine users' contribution in OSS communities from a perceived justice perspective. We adopted a mixed method of structural equation modeling (SEM) and artificial neural network (ANN) to conduct data analysis. The results indicated that perceived justice, which includes distributive justice, procedural justice and interactional justice, has significant effects on trust and satisfaction, both of which further determine contribution intention. The results imply that OSS communities need to improve users' perceived justice in order to facilitate their contribution behavior.",10.1177/02666669231191071
+1009,Article,The impacts of lockdown on open source software contributions during the COVID-19 pandemic,"The COVID-19 pandemic instigated widespread lockdowns, compelling millions to transition to work-from-home (WFH) arrangements and rely heavily on computer-mediated communications (CMC) for collaboration. This study examines the impacts of lockdown on innovation-driven work productivity, focusing on contributions to open source software (OSS) projects on GitHub, the world's largest OSS platform. By leveraging two lockdowns in China as natural experiments, we discover that developers in the 2021 Xi'an lockdown increased OSS contributions by 9.0 \\%, while those in the 2020 Wuhan lockdown reduced their contributions by 10.5 \\%. A subsequent survey study elucidates this divergence, uncovering an adaptation effect wherein Xi'an developers became more accustomed to the new norm of WFH over time, capitalizing on the flexibility and opportunities of remote work. Moreover, our findings across both lockdowns reveal that the lack of face-to-face (F2F) interactions significantly impeded OSS contributions, whereas the increased available time at home positively influenced them. This finding is especially noteworthy as it challenges the assumption that CMC can effortlessly substitute for F2F interactions without negatively affecting productivity. We further examine the impacts of stay-at-home orders in the United States (US) on OSS contributions and find no significant effects. Collectively, our research offers valuable insights into the multifaceted impacts of lockdown on productivity, shedding light on how individuals adapt to remote work norms during protracted disruptions like a pandemic. These insights provide various stakeholders, including individuals, organizations, and policymakers, with vital knowledge to prepare for future disruptions, foster sustainable resilience, and adeptly navigate the evolving landscape of remote work in a postpandemic world.",10.1016/j.respol.2023.104885
+1011,InProceedings,The promises and perils of open source software release and usage by government - evidence from GitHub and literature,"Open Source Software (OSS) is extensively utilized in industry and government because it allows for open access to the source code and allows for external involvement in the software development process. There are several factors driving this movement in a government setting, making it difficult to assess the adoption's success. Through a study of billions of rows of GitHub activity data, this research analyzes the production of OSS by administrations in German-speaking countries in detail and analyses the motivating factors and challenges to OSS adoption through a literature review. Similar studies have been conducted in other nations, with somewhat different approaches, foci, and different ways to identify public GitHub users as well as insiders and outsiders of OSS projects. 16 consequences of OSS usage and development are listed in the paper. On GitHub, we found 1021 OSS projects run by public agencies in largly German-speaking nations. We then compiled a list of the most popular projects based on commits and the most active public agencies in terms of projects. The research also finds automatic contributions by bots, which have not been taken into account in the literature so far, and demonstrates highly substantial positive correlations between commits, forks, and stars as proxy for the popularity of these projects. This research introduces a new method for identifying government organizations in OSS platforms and illuminates the possible positive and negative effects of the public sector's release and adoption of open source software.",10.1145/3598469.3598489

With advances in digital planning, surgical techniques, orthognathic surgery becomes increasingly safe, however, still a physiological factor that challenges the surgeon: bone repair. The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss (R) Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss (R)) and 10\\% collagen fibres in a block form and is sterilized by gamma-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss (R) Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss (R) Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.",10.21037/fomm-21-37

However, the maintenance and sustainability of OSS projects can be challenging. In this paper, we present the CrOSSD project, which aims to build a database of OSS projects and measure their current project ``health{''} status. In the project, we will use both quantitative and qualitative metrics to evaluate the health of OSS projects. The quantitative metrics will be gathered through automated crawling of meta information such as the number of contributors, commits and lines of code. Qualitative metrics will be gathered for selected ``critical{''} projects through manual analysis and automated tools, including aspects such as sustainability, funding, community engagement and adherence to security policies. The results of the analysis will be presented on a user-friendly web platform, which will allow users to view the health of individual OSS projects as well as the overall health of the OSS ecosystem.

In this position paper, we draw attention to another perspective: scientific insight itself is a complex and collaborative artifact under continuous development and in need of continuous quality assurance, and as such, has many parallels to software artifacts. Considering current calls for more open, collaborative and reproducible science; increasing demands for public accountability on matters of scientific integrity and credibility; methodological challenges coming with transdisciplinary science; political and communication tensions when scientific insight on societally relevant topics is to be translated to policy; and struggles to incentivize and reward academics who truly want to move into these directions beyond traditional publishing habits and cultures, we make the parallels between the emerging open science requirements and concepts already well-known in (open-source) software engineering research more explicit. We argue that the societal impact of software engineering expertise can reach far beyond the software engineering research community, and call upon the community members to pro-actively help driving the necessary systems and cultural changes towards more open and accountable research.",10.1109/ICSE-SEIS58686.2023.00020

To assess the foam with a focus on some specific components of its structure, such as hollow struts' cavities and open cells, the generalized characterizations must be overcome. This work presents image analysis methodologies, based on open-source software, tools, and plugins, to achieve the aforementioned characterizations. SiC and ZrO2 foams samples were analyzed and some of the results were compared with those accomplished with pieces of commercial software. The results show good agreement between open-source and commercial software applications, indicating that the presented methodologies can be freely applied by any researcher to analyze their foams.",10.1016/j.oceram.2023.100475

UISCEmod is a new open-source software for modelling water level time series, focused on ephemeral karstic wetlands, that requires minimal input information. UISCEmod contains both experimental and lumped hydrological models, and the calibration process is automated following a Bayesian approach. The main outputs of UISCEmod include volume, stage, inflow and outflow model time series, calibrated model parameters, and the associated uncertainties. UISCEmod was evaluated at 16 representative sites in Ireland obtaining Nash-Sutcliffe Efficiency (NSE) and Kling-Gupta Efficiency (KGE) above 0.85 for both stage and volume time series for most of the sites, showing its potential for covering the need for a simple, pragmatic, and flexible framework for modelling water levels in ephemeral karstic wetlands with relatively limited input data requirements.",10.1016/j.envsoft.2023.105761
+1026,Article,Understanding Mentors' Engagement in OSS Communities via Google Summer of Code,"A constant influx of newcomers is essential for the sustainability and success of open source software (OSS) projects. However, successful onboarding is always challenging because newcomers face various initial contributing barriers. To support newcomer onboarding, OSS communities widely adopt the mentoring approach. Despite its significance, previous mentoring studies tend to focus on the newcomer's perspective, leaving the mentor's perspective relatively under-studied. To better support mentoring, we study the popular Google Summer of Code (GSoC). It is a well-established global program that offers stipends and mentors to students aiming to bring more student developers into OSS development. We combine online data analysis, an email survey, and semi-structured interviews with the GSoC mentors to understand their motivations, challenges, strategies, and gains. We propose a taxonomy of GSoC mentors' engagement with four themes, ten categories, 34 sub-categories, and 118 codes, as well as the mentors' attitudes toward the codes. In particular, we find that mentors participating in GSoC are primarily intrinsically motivated, and some new motivators emerge adapting to the contemporary challenges, e.g., sustainability and advertisement of projects. Forty-one challenges and 52 strategies associated with the program timeline are identified, most of which are first time revealed. Although almost all the challenges are agreed upon by specific mentors, some mentors believe that several challenges are reasonable and even have a positive effect. For example, the cognitive differences between mentors and mentees can stimulate new perspectives. Most of the mentors agreed that they had adopted these strategies during the mentoring process, but a few strategies recommended by the GSoC administration were not agreed upon. Self-satisfaction, different skills, and peer recognition are the main gains of mentors to participate in GSoC. Eventually, we discuss practical implications for mentors, students, OSS communities, GSoC programs, and researchers.",10.1109/TSE.2023.3242415
+1030,Article,Using Modified Diffusion Models for Reliability Estimation of Open Source Software,"Software development is a highly unpredictable process, and ensuring software quality and reliability before releasing it to the market is crucial. One of the common practices during software development is the reuse of code. It can be achieved by utilizing libraries, frameworks, and other reusable components. Practically, when a fault is detected in replicated code, developers must check for similar faults in other copies, as there is a dependency between faults. To prevent recurrence of observed failures, developers must remove the corresponding leading fault and any related dependent faults. Many software reliability growth models (SRGMs) have been proposed and studied in the past, but most SRGMs assume that developers usually detect only one fault causing a failure. In actuality, it is necessary to consider the possibility of detecting multiple faults that may share similarities or dependencies. Additionally, some SRGMs rely on specific assumptions that may not always be valid, such as perfect debugging and/or immediate debugging. In this study, the modified diffusion models are proposed to handle these unrealistic situations, and are expected to better capture the dynamics of open source software (OSS) development. Experiments using real OSS data show that the proposed models can accurately describe the fault correction process of OSS. Finally, an optimal software release policy is proposed and studied. This policy takes into account some factors, including the remaining number of faults in the software, the expenses associated with identifying and rectifying those faults, and the level of market demand for the software. By considering these factors, developers can determine the optimal time to release the software to the market.",10.1109/ACCESS.2023.3279109

Details of educational P-N device models and simulation-based learning scenarios developed for this purpose are provided here. The presented approach allows students to learn the essential concepts related to P-N diodes experientially. These include some frequently observed nonidealities, closely mimicking experimental I-V measurements. Unlike most educational tools in this field, all simulations demonstrated here are performed locally on the student's computer using free and portable software, which eliminates the need for a live internet connection or time-consuming installations, making it easier to implement in a classroom and much more accessible to students. The paper also discusses the implementation of this supplementary tool and reports the results of a survey conducted to measure student satisfaction with it and its implementation approach. The presented method can be adapted to suit the needs of undergraduate and graduate students studying engineering courses that require an introduction to semiconductor devices.

The properties of OSS further complicate product assessment and maintenance for developers. This paper proposes a model for the iterative and multi-release OSS development process. Unlike traditional methods that oversimplify the problem by reducing the multi-decision space into a single-objective optimization problem, our approach suggests employing Multi-objective Evolutionary Algorithms (MOEAs) to solve the Optimal Release Time Planning Problem, enabling the simultaneous maximization of reliability and minimization of cost. We consider testing cost and system reliability, two critical dimensions, as the primary objectives, while also incorporating testing resource consumption as the third objective. The Non-dominated Sorting Genetic Algorithm II (NSGA-II) is chosen as the primary method for its effectiveness in MOEAs, with a special scenario outlined in the paper where NSGA-II may not guarantee optimal solutions. Demonstrating the practicality of our proposed method, we utilize open source data to assess release time and illustrate its superiority to NSGA-II. Numerical examples further showcase the model's effectiveness.",10.1109/ACCESS.2023.3323615

Computed tomography (CT) is commonly used to overcome projection errors in two-dimensional angular measurements of dog hindlimb alignment. Three-dimensional volume rendering (VR) techniques permit virtual positioning and variable projection, but the final CT-image that defines the projection plane for angular measurements remains two-dimensional.Objective We wanted to develop a true three-dimensional open-source technique to measure the alignments of the hind limbs of dogs in CT scanners.Methods We developed an open-source 3D Slicer plug-in, to perform angular measurements using vector calculations in three-dimensional space. In 113 CT-scans of canine pelvic limbs, femoral torsion, femoral varus, femorotibial rotation, tibial torsion, tibial varus and tibiotalar rotation angles were calculated and compared to an already validated technique using VoXim (R).Results Reference points were identified and measurements were possible in the 113 acquisitions. The greatest difference between the two techniques was 1.4 degrees at only one tibial torsion angle. Mean values for all Bland-Altman plots did not show significant differences and were less than 0.07 degrees for all comparisons.Discussion Based on these results we considered angular measurements of canine hind limb alignment in CT scans using the 3D Slicer extension program sufficiently accurate for clinical orthopedic and surgical purposes in veterinary medicine.Conclusion With our open-source 3D Slicer extension software, we provide a free accessible tool for veterinary orthopedic surgeons and thus we hope to improve angular measurements in CT-scans of canine hind limb deformities through true three-dimensionality.",10.1371/journal.pone.0283823

Among the various techniques available, photoplethysmography stands out as particularly promising for assessing vital signs such as heart rate, respiratory rate, oxygen saturation, and blood pressure. Despite the efficacy of this method, many commercially available wearables, bearing Conformit \\& eacute; Europ \\& eacute;enne marks and the approval of the Food and Drug Administration, are often integrated within proprietary, closed data ecosystems and are very expensive. In an effort to democratize access to affordable wearable devices, our research endeavored to develop an open-source photoplethysmographic sensor utilizing off-the-shelf hardware and open-source software components. The primary aim of this investigation was to ascertain whether the combination of off-the-shelf hardware components and open-source software yielded vital-sign measurements (specifically heart rate and respiratory rate) comparable to those obtained from more expensive, commercially endorsed medical devices. Conducted as a prospective, single-center study, the research involved the assessment of fifteen participants for three minutes in four distinct positions, supine, seated, standing, and walking in place. The sensor consisted of four PulseSensors measuring photoplethysmographic signals with green light in reflection mode. Subsequent signal processing utilized various open-source Python packages. The heart rate assessment involved the comparison of three distinct methodologies, while the respiratory rate analysis entailed the evaluation of fifteen different algorithmic combinations. For one-minute average heart rates' determination, the Neurokit process pipeline achieved the best results in a seated position with a Spearman's coefficient of 0.9 and a mean difference of 0.59 BPM. For the respiratory rate, the combined utilization of Neurokit and Charlton algorithms yielded the most favorable outcomes with a Spearman's coefficient of 0.82 and a mean difference of 1.90 BrPM.

The endpoint of the baking process is traditionally determined by subjective human experts and indirect temperature measurements, which can often result in unstandardized production. Current colorimeters are unavailable for onsite measurement due to limitations associated with contact measurement and environmental temperature. Instead of the abovementioned human experts and tabletop colorimeters, a handheld colorimeter was built based on the expertise of human specialists and utilizing a tabletop colorimeter and other optical steps. First, the selected samples were used to determine the upper and lower limits distinguishing light, medium, and heavy baking levels by using a tabletop colorimeter. Second, independent light sources and spectrometers were utilized to choose the characteristic and reference wavelengths at 450 and 830 nm, separately. Third, the handheld colorimeter, instead of human expert observation, was designed with functions such as distance sensing and Internet of Things capabilities. The baked index was derived from the calibration reflection and established statistical models. Here, the calibration reflection was defined by the normalized intensity at 450 nm relative to 830 nm, and statistical models were founded from the determined samples of upper and lower limits at 95-700 mm. The developed handheld colorimeter demonstrated high agreement rates of 96.84\\% and 93.86\\% in separate comparisons with tabletop colorimeters and human experts, respectively.

+1041,Article,A Method of Reliability Assessment Based on Trend Analysis for Open Source Software,"Software reliability growth model (SRGM) is used as one of the reliability assessment methods to assess the software reliability. In SRGM, the degree of reliability growth may fluctuate greatly according to change in the internal state of the software. It is called the change point (CP). Several researchers proposed the SRGM considering CP. In the open source software (OSS), there are many projects that continue development even after the software is released. Therefore, major updates with breaking changes may occur in it. The major updates can be a factor that causes a CP because it greatly changes the internal state of the OSS. This paper focuses on the relationship between CP and software updates. We collect OSS fault data from a bug tracking system. Moreover, we examine the behavior of SRGM before and after software updates. Furthermore, we discuss the applicability of SRGM for CP in OSS. Also, we compare the proposed model based on CP with the model without CP. As a result, we have confirmed that the SRGM can evaluate the reliability in the environment with major updates. Moreover, the proposed method performs better than without considering CP model. Especially, the exponential model's mean value function is the suitable method to assess the OSS reliability for the proposed method.",10.1142/S0218539324500049

Maintaining these versions involves initiating the transfer of changes for reuse. In the context of a pull-based development model, where the development branch remains current, the term ""backporting"" is coined to sustain stable versions. Stability requirements may necessitate fewer changes, compatible modifications, or security checks. Consequently, we conducted an analysis of 37,460 backports from 223,602 pull requests in open-source GitHub projects, aiming to identify types of incompatibilities encountered in real-life scenarios. We manually pinpointed various reasons why pull requests may lack compatibility with other versions, including contextual differences, varying dependencies, and statement-level alterations. This study constitutes the inaugural comprehensive characterization of changesets during the porting process across different versions with incompatibilities. The acquired insights can serve as a foundation for automated slicing and adaptation of changesets in stable software versions.",10.1145/3639478.3643079

However, the complexity and decentralized nature of the laboratory system has resulted in a situation where no one entity even knows about all the open source software projects in this ecosystem, let alone crude metrics of their health. In this article, we do the first external inventory of open source software repositories with a nexus to DOE labs. We posit that a project's need for sustainability support can be determined by comparing measures of active use to measures of active maintenance.",10.1109/MCSE.2024.3414951
+1048,Article,A Tertiary Study on Open-Source Software Research,"Open-source software (OSS) development has become prominent in the software industry over the last 20 years. OSS has transformed how software is developed, distributed, and maintained. This increase in popularity has led to extensive research in various domains of OSS, such as evolution, adoption, community and development processes.With the passage of time the volume of academic studies increased in the area of OSS, including Systematic Literature Reviews (SLRs) and Systematic Mapping Studies (SMS), which have provided valuable insights into specific aspects of OSS. The OSS domain is vast, with many areas that are still under explored. The fragmented nature of the existing studies presents challenges for both researchers and practitioners in identifying comprehensive research trends, gaps, future directions, and the cohesive understanding of the broader trends within the field. The secondary studies synthesize the literature to highlight findings and gaps of an area. The fragmentation of OSS academic literature limits the ability of researchers to identify unexplored or under-researched areas. This also creates challenges for both practitioners and researchers, as they lack awareness of the best practices, tools, technologies, and methodologies in a OSS domain. This study is motivated by the need to consolidate the extensive research conducted in the OSS domain, providing a holistic view that can guide future investigations and practical applications. The rationale for conducting this research lies in the opportunity to aggregate and classify existing OSS research areas, topics, and future directions through a systematic tertiary study. By synthesizing the findings from secondary studies, this research aims to offer a meta-level understanding of the OSS field, uncovering overlooked areas and defining a research agenda. The systematic approach, guided by the established protocol of Kitchenham, ensures that the study is conducted rigorously, with a focus on comprehensiveness and reliability. Ultimately, this research seeks to contribute to the OSS community by highlighting key research areas that require further exploration, thereby advancing the field and supporting the continued growth and innovation within OSS development. A systematic tertiary study is performed to cover all the systematic secondary studies in the area of OSS. The guidelines of Kitchenham are used for designing the protocol. The protocol details the research objectives, scope, search strategy, data extraction, quality assessment and synthesis. The protocol is detailed in section three for transparency. We have identified seventy-four studies that consist of twenty-five SMS and forty-nine SLR. The literature is mapped to a published taxonomy of OSS by Aksulu and Wade, however, the future directions are thematically analyzed. The results of mapping show that the highest number of studies (forty-seven) are in the sub-category of ``OSS categorization/research agenda{''}, whereas eight studies are mapped to the subcategory ``OSS vs Proprietary{''}. Both of these sub-categories fall in the main category of ``Conceptual{''}. The second major work is in the ``OSS Production{''} category in the sub-categories of ``Communities{''} (ten), ``Process{''} (eight), ``User and Developer Motivation{''} (nine), and ``Self-Organization (Product and Community Evolution){''} (six). Seven studies are also mapped to the sub-category of ``Software Quality{''} in the main category of ``Performance Metrics{''}. Other categories have fewer studies mapped to them. The areas identified, thematically, for future directions are ``OSS contributors{''}, ``OSS development process{''}, ``OSS evolution and prediction{''}, ``use of OSS in different domains{''}, and ``OSS adoption/adaptation/integration{''}. The mapping between ``key research areas{''} of systematic secondary studies and ``taxonomy categories{''} shows that there is no or little research in some of the categories of taxonomy, having potential of future research. The future directions thematic analysis will also aid researchers and practitioners.",10.1109/ACCESS.2024.3514075
+1049,Article,A dynamic perspective on software modularity in open source software (OSS) development: A configurational approach,"To reduce technical and task interdependencies, modularization has been considered important in OSS development. However, the existing literature implicitly takes a static view that software structure and organizational structure are established early on and change slowly over time, if at all. Such a view does not fully reflect the complex and dynamic nature of software development and tends to overlook the role played by human agents as they ramp involvement up and down over time. This study considers that coordination practice plays an important role in altering technical interdependencies in OSS development. This study investigates coordination practices that result in changes in software coupling-in particular, increases in software coupling. This study automatically analyzes the code in 72 software releases and 1033 task episodes of three successful OSS projects-GNU grep, IPython, and Scikit-image. This study takes a fine-grained practice-oriented perspective that views the way that the work is done as constituting the organization. In our conceptualization, OSS contributors use a configuration of multiple organizational elements, enacted and varying across specific episodes of practice. In line with this perspective, this study takes a configurational approach, uses fuzzy-set qualitative comparative analysis (fsQCA) to analyze episodes that led to decreases, no changes, and increases in software coupling during the inter-release periods in which the level of software coupling increased significantly, which we call focal period. We find that co-work involving multiple individuals tends to result in code that adds technical dependencies (increases in software coupling) during the focal period. To illustrate this beyond our fuzzy-set analysis, we present and discuss three episodes in narrative detail. The fine-grained, configurational analysis in this study supports the idea that the organizing process is ongoing enactment. In this study, OSS systems are an amalgam of code that builds up in different episodes each possibly different organizational configurations, rather than thinking of the OSS systems or projects as static or singular.",10.1016/j.infoandorg.2023.100499
+1051,Article,A multi-release reliability model of open source software with fault detection obeying three-parameter lifetime distribution,"With the development of open source software (OSS), software reliability has become an important issue. Due to the complexity of OSS development and testing environment, the fault detection rate of OSS will show a variety of changes. The existing OSS reliability models cannot fully adapt to the complex changes of OSS fault detection. In this paper, we proposed a multi-release OSS reliability model based on three-parameter lifetime distribution. The proposed model can effectively adapt to the complicated changes of fault detection in the processes of development and testing of OSS. Experimental results indicate that the proposed model has the better fitting and predictive performance compared with other multi-release OSS reliability models. Moreover, the proposed model can better adapt to the variety of OSS fault detection environment, and assist developers to evaluate the reliability of OSS.",10.1038/s41598-024-70536-x
+1052,Article,A resilience-based framework for assessing the evolution of open source software projects,"Open source software (OSS) has been developing for more than two decades. It originated as a movement with the introduction of the first free/libre OSS operating system, became a popular trend among the developer community, led to enterprise solutions widely embraced by the global market, and began garnering attention from significant players in the software industry (such as IBM's acquisition of RedHat). Throughout the years, numerous software assessment models have been suggested, some of which were created specifically for OSS projects. Most of these assessment models focus on software quality and maintainability. Some models are taking under consideration health aspects of OSS projects. Despite the multitude of these models, there is yet to be a universally accepted model for assessing OSS projects. In this work, we aim to adapt the City Resilience Framework (CRF) for use in OSS projects to establish a strong theoretical foundation for OSS evaluation focusing on the project's resilience as it evolves over time. We would like to highlight that our goal with the proposed assessment model is not to compare two OSS solutions with each other, in terms of resilience, or even do a resilience ranking between the available OSS tools. We are aiming to investigate resilience of an OSS project as it evolves and identify possible opportunities of improvements in the four dimensions we are defining. These dimensions are as follows: source code, business and legal, integration and reuse, and social (community). The CRF is a framework that was introduced to measure urban resilience and most specifically how cities' resilience is changing as they evolve. We believe that a software evaluation model that focuses on resilience can complement the pre-existing models based on software quality and software health. Although concepts that are related to resilience, like sustainability or viability, already appear in literature, to our best knowledge, there is no OSS assessment model that evaluates the resilience of an OSS project. We argue that cities and OSS projects are both dynamically evolving systems with similar characteristics. The proposed framework utilizes both quantitative and qualitative indicators, which is viewed as an advantage. Lastly, we would like to emphasize that the framework has been tested on the enterprise software domain as part of this study, evaluating five major versions of six OSS projects, Laravel, Composer, PHPMyAdmin, OKApi, PatternalPHP, and PHPExcel, the first three of which are intuitively considered resilient and the three latter nonresilient, to provide a preliminary validation of the models' ability to distinguish between resilient and not resilient projects.",10.1002/smr.2597
+1054,Article,"A travel time matrix data set for the Helsinki region 2023 that is sensitive to time, mode and interpersonal differences, and uses open data and novel open-source software","Travel times between different locations form the basis for most contemporary measures of spatial accessibility. Travel times allow to estimate the potential for interaction between people and places, and is therefore a vital measure for understanding the functioning, sustainability, and equity of cities. Here, we provide an open travel time matrix dataset that describes travel times between the centroids of all cells in a grid (N = 13,132) covering the metropolitan area of Helsinki, Finland. The travel times recorded in the dataset follow a door-to-door approach that provides comparable travel times for walking, cycling, public transport and car journeys, including all legs of each trip by each mode, such as the walk to a bus stop, or the search for a parking spot. We used the r5py Python package, that we developed specifically for this computation. The data are sensitive to diurnal variations and to variations between people (e.g. slow and fast walking speed). We validated the data against the Google Directions API and present use cases from a planning practice. The five key principles that guided the data set design and production - comparability, simplicity, reproducibility, transferability, and sensitivity to temporal and interpersonal variations - ensure that urban and transport planners, business and researchers alike can use the data in a wide range of applications.",10.1038/s41597-024-03689-z

+1058,Article,Ambush From All Sides: Understanding Security Threats in Open-Source Software CI/CD Pipelines,"The continuous integration and continuous deployment (CI/CD) pipelines are widely adopted on Internet hosting platforms, such as GitHub. However, current CI/CD pipelines suffer from malicious code and severe vulnerabilities. Even worse, people have not been fully aware of its attack surfaces and the corresponding impacts. Therefore, in this paper, we conduct a large-scale measurement and a systematic analysis to reveal the attack surfaces of the CI/CD pipeline and quantify their security impacts. Specifically, for the measurement, we collect a data set of 320,000+ CI/CD pipeline-configured GitHub repositories and build an analysis tool to parse the CI/CD pipelines and extract security-critical usages. Our measurement reveals that the script runtimes are prone to code hiding while the script usage update is not in time, giving attackers chances to hide malicious code and exploit existing vulnerabilities. Moreover, even the scripts from verified creators may contain severe vulnerabilities. Besides current CI/CD ecosystem heavily relies on several core scripts, which may lead to a single point of failure. While the CI/CD pipelines contain sensitive information/operations, making them the attacker's favorite targets. Inspired by the measurement findings, we abstract the threat model and the attack approach toward CI/CD pipelines, followed by a systematic analysis of attack surfaces, attack strategies, and the corresponding impacts. We further launch case studies on five attacks in real-world CI/CD environments to validate the revealed attack surfaces. Finally, we give suggestions on mitigating attacks on CI/CD scripts, including securing CI/CD configurations, securing CI/CD scripts, and improving CI/CD infrastructure.",10.1109/TDSC.2023.3253572
+1059,InProceedings,An Exploratory Mixed-methods Study on General Data Protection Regulation (GDPR) Compliance in Open-Source Software,"Background: Governments worldwide are considering data privacy regulations. These laws, such as the European Union’s General Data Protection Regulation (GDPR), require software developers to meet privacy-related requirements when interacting with users’ data. Prior research describes the impact of such laws on software development, but only for commercial software. Although open-source software is commonly integrated into regulated software, and thus must be engineered or adapted for compliance, we do not know how such laws impact open-source software development. Aims: To understand how data privacy laws affect open-source software (OSS) development, we focus on the European Union’s GDPR, as it is the most prominent such law. We investigated how GDPR compliance activities influence OSS developer activity (RQ1), how OSS developers perceive fulfilling GDPR requirements (RQ2), the most challenging GDPR requirements to implement (RQ3), and how OSS developers assess GDPR compliance (RQ4). Method: We distributed an online survey to explore perceptions of GDPR implementations from open-source developers (N=56). To augment this analysis, we further conducted a repository mining study to analyze development metrics on pull requests (N=31,462) submitted to open-source GitHub repositories. Results: Our results suggest GDPR policies complicate OSS development and introduce challenges, primarily regarding the management of users’ data, implementation costs and time, and assessments of compliance. Moreover, we observed negative perceptions of the GDPR from OSS developers and significant increases in development activity, in particular metrics related to coding and reviewing, on GitHub pull requests related to GDPR compliance. Conclusions: Our findings provide future research directions and implications for improving data privacy policies, motivating the need for relevant resources and automated tools to support data privacy regulation implementation and compliance efforts in OSS.",10.1145/3674805.3686692
+1060,Article,An Open-Source Software Reliability Model Considering Learning Factors and Stochastically Introduced Faults,"In recent years, software development models have undergone changes. In order to meet user needs and functional changes, open-source software continuously improves its software quality through successive releases. Due to the iterative development process of open-source software, open-source software testing also requires continuous learning to understand the changes in the software. Therefore, the fault detection process of open-source software involves a learning process. Additionally, the complexity and uncertainty of the open-source software development process also lead to stochastically introduced faults when troubleshooting in the open-source software debugging process. Considering the phenomenon of learning factors and the random introduction of faults during the testing process of open-source software, this paper proposes a reliability modeling method for open-source software that considers learning factors and the random introduction of faults. Least square estimation and maximal likelihood estimation are used to determine the model parameters. Four fault data sets from Apache open-source software projects are used to compare the model performances. Experimental results indicate that the proposed model is superior to other models. The proposed model can accurately predict the number of remaining faults in the open-source software and be used for actual open-source software reliability evaluation.",10.3390/app14020708
+1061,Article,An empirical examination of newcomer contribution costs in established OSS communities: a knowledge-based perspective,"PurposeTo remain sustainable, open source software (OSS) projects must attract new members-or newcomers-who make contributions. In this paper, the authors develop a set of hypotheses based on the knowledge barriers framework that examines how OSS communities can encourage contributions from newcomers.Design/methodology/approachEmploying longitudinal data from the source code repositories of 232 OSS projects over a two-year period, the authors employ a Poisson-based mixed model to test how community characteristics, such as the main drivers of knowledge-based costs, relate to newcomers' contributions.FindingsThe results indicate that community characteristics, such as programming language choice, documentation effort and code structure instability, are the main drivers of knowledge-based contribution costs. The findings also suggest that managing these costs can result in more inclusive OSS communities, as evidenced by the number of contributing newcomers; the authors highlight the importance of maintaining documentation efforts for OSS communities.Originality/valueThis paper assumes that motivational factors are a necessary but insufficient condition for newcomer participation in OSS projects and that the cost to participation should be considered. Using the knowledge barriers framework, this paper identifies the main knowledge-based costs that hinder newcomer participation. To the best of the authors' knowledge, this is the first empirical study that does not limit data collection to a single hosting platform (e.g., SourceForge), which improves the generalizability of the findings.",10.1108/INTR-08-2022-0594
+1065,Article,An open GNSS spoofing data repository: characterization and impact analysis with FGI-GSRx open-source software-defined receiver,"Spoofing is becoming a prevalent threat to the users of Global Navigation Satellite Systems (GNSS). It is important to deepen our understanding of spoofing attacks and develop resilient techniques to effectively combat this threat. Detecting and mitigating these attacks requires thorough testing, typically conducted in a laboratory environment through the establishment of a spoofing test-bed. The complexity, cost and resource demands of creating such a test-bed underscore the necessity of utilizing openly available datasets. To address this need, this paper introduces a new GNSS spoofing data repository from Finnish Geospatial Research Institute (FGI) named hereafter as `FGI-SpoofRepo'. This data repository consists of raw In-phase and Quadrature (I/Q) data of live recordings of GPS L1 C/A, Galileo E1, GPS L5, and Galileo E5a signals. These datasets encompass three distinct types of spoofing characteristics (synchronous, asynchronous, and meaconing), making them very useful example candidates of open data for testing the performance of any anti-spoofing techniques (be it detection or mitigation). The inclusion of live signals in multiple GNSS frequencies and the presence of cryptographic signatures in Galileo E1 signal make these datasets potential benchmarks for assessing the resilience performance of multi-frequency multi-constellation receivers. The analysis of the datasets is carried out with an open-source MATLAB-based software-defined receiver, FGI-GSRx. An updated version of FGI-GSRx, equipped with the necessary modifications for processing and analyzing the new datasets, is released alongside the datasets. Therefore, the GNSS research community can utilize the open-source FGI-GSRx or any third-party SDR to process the publicly available raw I/Q data for implementation, testing and validation of any new anti-spoofing technique. The results show that time-synchronous spoofing seamlessly takes over positioning solution, while time-asynchronous spoofing acts as noise or in some cases, completely prevent the receiver from providing a positioning solution. Signal re-acquisition during an ongoing spoofing attack (cold start), the receiver tends to lock onto the spoofing signal with the highest peak, posing a potential threat to GNSS receivers without assisted information. Overall, this research aims to advance the understanding of complex spoofing attacks on GNSS signals, providing insight into enhancing resilience in navigation systems.",10.1007/s10291-024-01719-2

Although designed to archive deduplicated small files thanks to the use of a Merkle tree as the underlying data structure, querying the SWH dataset presents challenges due to the nature of these structures, which organize content based on hash values rather than any locality principle. The magnitude of the repository, coupled with the resource-intensive nature of the download process, highlights the need for specialized infrastructure and computational resources to effectively handle and study the extensive dataset housed within SWH. Currently, there is a lack of infrastructures specifically tailored for running analytics on the SWH dataset, leaving users to handle these issues manually. To address these challenges, we implemented the SWH-Analytics (SWHA) framework, a development environment that transparently runs custom analytic applications on publicly available software data preserved over time by SWH. Specifically, this work shows how SWHA can be effectively exploited to study usage patterns of free and open-source software licenses, highlighting the need to improve license literacy among developers.",10.1007/s11227-024-06069-x

In the context of collaborative software development, producing sound architectural documentation, where architectural views play a central role, is a crucial aspect for effective teamwork. Despite their importance, the use of architectural views in open-source projects to date remains only marginally explored. Goal: We aim at conducting a comprehensive analysis on an extensive corpus of open-source architectural views. The goal is to understand (i) what the ``history{''} of architectural views is, (ii) how architectural views are represented, and (iii) what architectural views are used for in the context of open-source projects. Methods: We leverage a software repository mining process to systematically construct a dataset of 15k architectural views. Then, we perform (i) a quantitative analysis on the metadata of all 15k views and (ii) a qualitative analysis on a statistically-relevant sample of 373 views. Results: Most projects rely on a single architectural view, which is often used to document a medium or high level description of the architecture. Views are usually created at either the beginning or at the end of a project, are rarely updated, and tend to be maintained by a single contributor. Views usually adopt an informal colored notation without a supporting legend and frequently report technologies used.

A total of 2763 Asian Americans aged 20 and older were included in this analysis. The primary predictor, acculturation score, was determined by three questions: (i) language spoken at home (higher score for English), (ii) country of birth (higher score for United States) and (iii) length of time in the United States. Dental floss use, dental visits and unmet dental care needs were included as outcomes in this study. Descriptive statistics and logistic regressions were used to analyse the samples.ResultsAcculturation was significantly associated with dental health behaviours: Individuals with higher levels of acculturation were more likely than less acculturated individuals to use dental floss (81.0\\% vs. 63.9\\%, respectively) and visit the dentist regularly (76.7\\% vs. 66.9\\% respectively). Insurance status moderated the association between acculturation and dental visits: Acculturation was significantly associated with dental visits in the past year among insured individuals (OR = 1.70, 95\\% CI: 1.29-2.23), but not among uninsured individuals. Unmet dental care needs were present in 11.1\\% of participants. While costs and insurance were the top two determinants of access to care, individuals with and without insurance differed with regard to their third major reason for unmet dental care needs: Being `too busy' and not wanting to spend money on dental care.ConclusionsAmong the Asian population in the United States, those with high acculturation scores were more likely to engage in dental flossing and visit the dentist regularly compared to those Asians with lower acculturation scores. To encourage dental flossing and regular dental visits among Asians with lower acculturation scores, cultural adaptation and language accessibility suggests being considered. Future research is necessary to confirm the moderating effect of insurance status on the association between acculturation and regular dental visits. Additionally, our findings emphasize the impact of costs and insurance on access to dental care among Asians in the United States, highlighting the importance of future public health programmes in addressing these barriers.",10.1111/cdoe.12906

In light of these challenges, this study has concentrated on automating cybersecurity processes, particularly those pertaining to continuous vulnerability detection. A cybersecurity vulnerability scanner was developed, which is freely available to the community and does not necessitate any prior expertise from the operator. The effectiveness of this tool was evaluated by IT companies and systems engineers, some of whom had no background in cybersecurity. The findings indicate that the scanner proved to be efficient, precise, and easy to use. It assisted the operators in safeguarding their systems in an automated fashion, as part of their security audit strategy.",10.3390/electronics13050873
+1080,Article,BUSClean: Open-source software for breast ultrasound image pre-processing and knowledge extraction for medical AI,"Development of artificial intelligence (AI) for medical imaging demands curation and cleaning of large-scale clinical datasets comprising hundreds of thousands of images. Some modalities, such as mammography, contain highly standardized imaging. In contrast, breast ultrasound imaging (BUS) can contain many irregularities not indicated by scan metadata, such as enhanced scan modes, sonographer annotations, or additional views. We present an open-source software solution for automatically processing clinical BUS datasets. The algorithm performs BUS scan filtering (flagging of invalid and non-B-mode scans), cleaning (dual-view scan detection, scan area cropping, and caliper detection), and knowledge extraction (BI-RADS Labeling and Measurement fields) from sonographer annotations. Its modular design enables users to adapt it to new settings. Experiments on an internal testing dataset of 430 clinical BUS images achieve >95\\% sensitivity and >98\\% specificity in detecting every type of text annotation, >98\\% sensitivity and specificity in detecting scans with blood flow highlighting, alternative scan modes, or invalid scans. A case study on a completely external, public dataset of BUS scans found that BUSClean identified text annotations and scans with blood flow highlighting with 88.6\\% and 90.9\\% sensitivity and 98.3\\% and 99.9\\% specificity, respectively. Adaptation of the lesion caliper detection method to account for a type of caliper specific to the case study demonstrates the intended use of BUSClean in new data distributions and improved performance in lesion caliper detection from 43.3\\% and 93.3\\% out-of-the-box to 92.1\\% and 92.3\\% sensitivity and specificity, respectively.

They use various technologies to create solutions that boost and advance healthcare systems and healthcare delivery. Open-source software (OSS) technology has become an essential component of startups' toolkits, providing various advantages, such as free access to source codes and opportunities for innovation. Research on OSS in healthcare startups is limited, so our study aims to investigate how healthtech startups perceive the influence of OSS on product development and to identify the challenges they face. To meet this objective, we conducted an empirical study with six health-tech startups, using semi-structured interviews. Thematic analysiswas performed on the collected data to identify common themes and subthemes related to the research objective. The findings showed that health-tech startups benefit from the cost efficiency, scalability, and customization of OSS. Open-source software tools, reshape development and promote efficient code management, provide community support, and reduce costs. However, they demand OSS knowledge, management of updates, regulatory compliance, and heightened cybersecurity. Our study adds to the body of knowledge on OSS and healthcare startups and the connection between them. We provide recommendations for health-tech startups, such as embracing OSS tools for their benefits, investing in education and training, and engaging with the OSS community for comprehensive support in their product development processes.",10.1007/978-3-031-53227-6\\_19

+1083,Article,Biophysical essentials - A full stack open-source software framework for conserved and advanced analysis of patch-clamp recordings,"Background and Objectives: Patch-Clamp recordings allow for in depth electrophysiological characterization of single cells, their general biophysical properties as well as characteristics of voltage- and ligand-gated ionic currents. Different acquisition modes, such as whole-cell patch-clamp recordings in the current or voltage clamp configuration, capacitance measurements or single channel recordings from cultured cells as well as acute brain slices are routinely performed for these purposes. Nevertheless, multipurpose transparent and adaptable software tools to perform reproducible state-of-the-art analysis of multiple experiment types and to manage larger sets of experimental data are currently unavailable. Methods: Biophysical Essentials (BPE) was developed as an open-source full stack python software for transparent and reproducible analysis of electrophysiological recordings. For validation, BPE results were compared with manually analyzed single-cell patch-clamp data acquired from a human in vitro nociceptor-model and mouse dorsal root ganglia neurons. Results: While initially designed to improve time consuming and repetitive analysis steps, BPE was further optimized as a technical software solution for entire workflow processing including data acquisition, data preprocessing, normalization and visualization and of single recordings up to stacked calculations and statistics of multiple experiments. BPE can operate with different file formats from different amplifier systems and producers. An in-process database logs all analysis steps reproducible review and serves as a central storage point for recordings. Statistical testing as well as advanced analysis functions like Boltzmann-fitting and dimensional reduction methods further support the researchers' needs in projects involving electrophysiology techniques. Conclusions: BPE extends beyond available patch-clamp specific, open source - and commercial analysis tools in particular because of reproducible and sharable analysis workflows. BPE enables full analysis from raw data acquisition to publication ready result visualizations - all within one single program. Thereby, BPE significantly enhances transparency in the analytical process of patch-clamp data analysis. BPEs function scope is completely accessible through an easy-to-use graphical user interface eliminating the need for programing language proficiency as required by many community patch-clamp analysis frameworks and algorithms.",10.1016/j.cmpb.2024.108328

Since the co-creation of value involves customers participating in the creation of product offerings voluntarily and actively, this investigation tries to understand what drives customers to participate in these co-creation initiatives. To do so, this study employs a probabilistic sample of 683 users enrolled in Linux forums for open-source software distributions. The path analysis and bootstrap samples revealed that customers who exhibit a high innate innovativeness and feel that they belong in the online community show a greater motivation towards platform exploration and participation in co-creation. Moreover, the effect of this synergic interaction on their co-creation participation was partially mediated by the normative dimension of their intrinsic motivation, while the hedonic dimension was not a strong predictor of co-creation contributions.

The purpose of this study was to radiologically evaluate the efficacy of using Bio-Oss Collagen with Concentrated Growth Factor (CGF) as grafting materials for OSFE with simultaneous implant placement in the atrophic maxilla after one year of functional loading.MethodsA total of 126 implants were placed for 123 patients. Our inclusion criteria were patients with Residual Bone Height (RBH) <= 5 whom underwent OSFE procedure and simultaneous implant placement with different grafting materials: Group A with no grafting materials, Group B with Bio-Oss bone graft, and Group C with Bio-Oss Collagen with CGF. The Implants Survival Rate (ISR) was the primary outcome variable. Secondary outcome variables included radiographic measurements assessed at four follow-up time points, the Implant Stability Quotient (ISQ), and bone density (B). Indicators of bone formation were compared at different time points.

+1089,Article,COBRAPRO: An Open-Source Software for the Doyle-Fuller-Newman Model with Co-Simulation Parameter Optimization Framework,"This paper presents COBRAPRO, a new open-source Doyle-Fuller-Newman (DFN) model software package with an integrated closed-loop parameter optimization routine. A key challenge in DFN model parameterization is that parameters measured from cell tear-down experiments cannot be directly used in simulations, and parameter identification is required to accurately reflect real-world battery dynamics However, existing open-source DFN codes lack the capability to perform parameter identification and operate in open-loop mode. COBRAPRO addresses this gap by implementing a systematic parameterization pipeline to accurately determine parameters using battery current and voltage data. Concepts from structural and practical identifiability are utilized to determine parameters that can be fixed to their experimental values and parameters that are suitable for optimization. In the parameter identification process, particle swarm optimization is used to minimize the error between experimental data and simulation results. Additionally, COBRAPRO incorporates a robust method to determine consistent initial conditions and utilizes a fast numerical solver for improved performance. We demonstrate COBRAPRO's parameter identification framework on reference performance test data obtained from LG INR21700-M50T cells. The parameterized model is validated against driving cycle data, showing good agreement between the experimental and simulation results.",10.1149/1945-7111/ad7292

In this study, OSs in eastern China were investigated to understand their diurnal evolution, source, and volatility using high-resolution mass spectrometry. In polluted days, we identified a total of 5,147 organic molecules, including 1,206 OS molecules. The average molecular weight (m.w.) and carbon chain length of OSs in this study exceeded the commonly recognized range (500 Da). OSs were mostly composed of newly formed low oxidation state compounds as well as aged aliphatic and aromatic ones. The number and abundance of aromatic and aliphatic OSs with low saturation, volatility, O/C-w as well as H/C-w increased greatly with rising PM2.5 concentrations. The daytime photo-oxidation resulted in a large number of high m.w. (HMW, > 500 Da) OSs. OSs with m.w. <500 Da, and many oxygen atoms were newly generated during the nighttime, mainly dominated by liquid-phase oxidation processes. The result of OSs with higher m.w. and lower volatility was due to increased dimerization and oligomerization. During pollution formatting, OSs with small DBE values (between 0 and 6) appeared; meanwhile, the number of highly unsaturated OSs with DBE > 7 (mainly aromatic OSs) increased by about 34\\%. This study is useful for clarifying the secondary formation and properties of HMW OSs in a polluted environment in China.",10.1016/j.atmosres.2024.107258
+1091,Article,Characterizing Usability Issue Discussions in Open Source Software Projects,"Usability is a crucial factor but one of the most neglected concerns in open source software (OSS). While far from an ideal approach, a common practice that OSS communities adopt to collaboratively address usability is through discussions on issue tracking systems (ITSs). However, there is little knowledge about the extent to which OSS community members engage in usability issue discussions, the aspects of usability they frequently target, and the characteristics of their collaboration around usability issue discussions. This knowledge is important for providing practical recommendations and research directions to better support OSS communities in addressing this important topic and improve OSS usability in general. To help achieve this goal, we performed an extensive empirical study on issues discussed in five popular OSS applications: three data science notebook projects (Jupyter Lab, Google Colab, and CoCalc) and two code editor projects (VSCode and Atom). Our results indicated that while usability issues are extensively discussed in the OSS projects, their scope tended to be limited to efficiency and aesthetics. Additionally, these issues are more frequently posted by experienced community members and display distinguishable characteristics, such as involving more visual communication and more participants. Our results provide important implications that can inform the OSS practitioners to better engage the community in usability issue discussion and shed light on future research efforts toward collaboration techniques and tools for discussing niche topics in diverse communities, such as the usability issues in the OSS context.",10.1145/3637307
+1092,Article,Classification of open source software bug report based on transfer learning,"Currently, the feature richness of text encoding vectors in the bug report classification model based on deep learning is limited by the size of the domain dataset and the quality of the text. However, it is difficult to further enrich the features of text encoding vectors. At the same time, most existing bug report classification methods ignore the submitter's personal information. To solve these problems, we construct nine personal information characteristics of bug report submitters in GitHub by survey. Then, we propose a GitHub bug report classification method named personal information fine‐tuning network (PIFTNet) based on transfer learning and the submitter's personal information. PIFTNet transfers the general text feature vectors in bidirectional encoder representation from transformers (BERT) to the domain of bug report classification by fine‐tuning the pre‐training parameters in BERT. It also combines the text characteristics and the characteristics of the submitter's personal information to construct the classification model. In addition, we propose a two‐stage training method to alleviate the catastrophic changes in the pre‐training parameters and loss of the initially learned knowledge caused by direct training of PIFTNet. We verify the proposed PIFTNet on the dataset extracted from GitHub and empirical results prove the effectiveness of PIFTNet.",10.1111/exsy.13184

We examine how projects engage in distinct ``discursive modulation practices{''} to imprint the community's shared core doctrines and design principles onto the software thereby shaping its novelty and complexity. We borrow the concept of modulation from audio synthesis to explain how a preexisting signal-in our case, the ongoing community discourse-is modulated to produce varying sounds-in our case, the novelty and complexity of the software. The concept of modulation offers a lens to understand how emergent, community-wide development activities are influenced by filtering discursive positions and mixing those positions, thereby shaping the artifact's novelty and complexity. Our research shows that the modulation of novelty exhibits a range from ``proximal{''} to ``distal{''} searches for new features, while the modulation of complexity varies between ``integration{''} and ``deprecation.{''} By drawing on these concepts, we formulate a theory that explains how modulation results in alternative OSS community approaches to shaping software novelty and complexity and how this process reflects and is reflected in the resulting software artifact.",10.25300/MISQ/2023/16872

We then investigate the relationship of such behavior to what the formal policies prescribe, through their own governance priorities and how their members internalize them. Our findings indicate that a greater amount of policy over a governed topic doesn't elicit more governed activity on that topic, but does predict greater internalization by community members.

EPIq features include: the adiabatic and non-adiabatic phonon dispersion, superconducting properties (including the superconducting band gap in the Migdal-Eliashberg formulation), double-resonant Raman spectra and lifetime of excited carriers. The possibility to customize most of its input makes EPIq a versatile and interoperable tool. Particularly relevant is the interaction with the Stochastic Self-Consistent Harmonic Approximation (SSCHA) allowing anharmonic effects to be included in the calculation of electron -properties.

Materials and methods Seventy-five adult subjects showing approximately 40\\% proximal gingival bleeding were randomized to receive OHt (1 session weekly over 8 weeks) using toothbrush and dental floss or toothbrush alone. The subjects were then followed over 180 days without professional guidance. Primary outcomes were mean interproximal Gingival Index (GI) and GI = 2 (gingival bleeding). Mixed linear models were used for the comparison between groups (p < 0.05). Results68 subjects received OHt, 48 subjects completed the 180-day follow-up. Subjects maintained adequate oral hygiene routines. Besides a reduction in gingival inflammation, no alterations in gingival status were observed among groups, subjects additionally instructed to use dental floss showing a mean interproximal GI = 2 of 12.8 +/- 2.5 compared with 19.8 +/- 2.2 for subjects limited to tooth brushing alone. Conclusions OHt intensive training promotes gingival health and maintenance lasting at least 6 months without professional supervision reinforcing important principles: (i) dental health professionals should dedicate time training and motivating their patients to reach adequate self-performed plaque control; and (ii) the adjunctive use of dental floss appears essential to reduce interproximal gingival inflammation in subjects with intact interdental papillae. Clinical relevance Dentists need to invest time in training/motivating/engage their patients to achieve adequate OH; adjunct flossing in subjects with papilla filling the interdental space appears essential to reach and maintain gingival health.

This research seeks to address the existing gap in accessible tools for high-throughput analysis of endothelial tube formation and cell invasion in vitro, facilitating the rapid assessment of drug sensitivity.MethodsOur approach involved annotating over 1000 2 mm Z-stacks of cancer and endothelial cell co-culture model and training machine learning models to automatically calculate cell coverage, cancer invasion depth, and microvessel dynamics. Specifically, cell coverage area was computed using focus stacking and Gaussian mixture models to generate thresholded Z-projections. Cancer invasion depth was determined using a ResNet-50 binary classification model, identifying which Z-planes contained invaded cells and measuring the total invasion depth. Lastly, microvessel dynamics were assessed through a U-Net Xception-style segmentation model for vessel prediction, the DisPerSE algorithm to extract an embedded graph, then graph analysis to quantify microvessel length and connectivity. To further validate our software, we reanalyzed an image set from a high-throughput drug screen involving a chemotherapy agent on a 3D cervical and endothelial co-culture model. Lastly, we applied this software to two naive image datasets from coculture lumen and microvascular fragment models.ResultsThe software accurately measured cell coverage, cancer invasion, and microvessel length, yielding drug sensitivity IC50 values with a 95\\% confidence level compared to manual calculations.

Furthermore, the software was able to calculate cell coverage, microvessel length, and invasion depth from two additional microphysiological models that were imaged with confocal microscopy, highlighting the versatility of the software.ConclusionsOur free and open source software offers an automated solution for quantifying 3D cell behavior in microphysiological models assessed using non-confocal microscopy, providing the broader Cellular and Molecular Bioengineering community with an alternative to standard confocal microscopy paired with proprietary software.This software can be found in our GitHub repository: https://github.com/fogg-lab/tissue-model-analysis-tools.",10.1007/s12195-024-00821-2
+1111,Article,Environmental effects on the experimental modal parameters of masonry buildings: experiences from the Italian Seismic Observatory of Structures (OSS) network,"The paper presents an in-depth analysis of the ambient dynamic behavior of nine masonry buildings monitored by the Italian Seismic Observatory of Structures (OSS). Addressing a significant knowledge gap affecting this structural type, the study reveals how daily and seasonal fluctuations in environmental factors have a notable influence on its experimental modal parameters. A robust frequency-domain tracking algorithm is first developed to identify and follow the evolution of modal parameters over time, exploiting ambient vibration recordings acquired at sub-daily intervals on the structures. The procedure is systematically applied to the entire portfolio of case-study buildings and, in the first year of training, integrated with measurements of environmental parameters provided by nearby weather stations. The multivariate regression analysis indicates that temperature variation is the primary driver of the observed wandering of natural frequencies. The frequency-temperature relationship shows a positive correlation above zero degrees and, in several cases, a significant degree of nonlinearity already present in low-frequency global modes. Simple predictive models are proposed to address such nonlinear behavior, including freezing conditions and accounting for internal heating during winter. Leveraging these novel insights, the work develops strategies to improve the efficiency of data acquisition protocols and training periods, enabling the near-future extension of real-time condition assessment methodologies to the entire OSS network.",10.1007/s13349-024-00847-0

The goal was to assess whether the use of open-source software can contribute to improving learning environments in a higher secondary education institution in Mexico. A quantitative, non-experimental, transactional, descriptive, and correlational research method was employed. The results showed that open-source software is a valuable support in developing new didactic strategies. The findings revealed confidence among teachers in using open-source software as a didactic strategy, and students considered starting to use open-source software from the first semesters. This research is original as open-source software supports the development of new didactic strategies. The limitation was that teachers use proprietary software, and it is likely more challenging for them to use opensource software.",10.18421/TEM134-50
+1115,Article,Evaluation of Peri-Implantitis Bone Defect Healing: Comparing the Efficacy of Small-Particle Dentin and Bio-Oss in Bone Density Attenuation,"Introduction: Peri-implantitis is a serious complication in dental implantology that, if left untreated, may lead to implant loss and systemic diseases. Effective regeneration of bone defects resulting from peri-implantitis is crucial to maintaining the functionality of dental implants. Purpose of the Study: The study aimed to compare the effectiveness of fine-particle dentin and Bio-Oss in the reconstruction of bone defects caused by peri-implantitis. Materials and Methods: The study included a comprehensive radiological assessment of changes in bone density over time. Bone density was assessed using Hounsfield Units (HUs) as a measure of bone attenuation, with radiological assessments performed at 8- and 12-week intervals during the healing process. The study included participants ranging in age from 30 to 65 years. Fifty-seven patients were divided into three groups: 22 patients received small-particle dentin, 15 received Bio-Oss, and 20 controls without bone substitute material. Results: The fine-dentin group showed a 20\\% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15\\% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5\\% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95\\% successful integration in the fine dentin group, 85\\% in the Bio-Oss group, and 70\\% in the control group. The fine-dentin group showed a 20\\% increase in bone density after 8 weeks (p < 0.05), while the Bio-Oss group showed a 15\\% increase after 12 weeks (p < 0.05). The control group showed minimal changes in bone density (5\\% after 12 weeks), which was not statistically significant. Clinical evaluations showed 95\\% successful integration in the fine-dentin group, 85\\% in the Bio-Oss group, and 70\\% in the control group. Conclusions: Both fine-particle dentin and Bio-Oss significantly improved bone density compared to the control group. Fine-particle dentin is suitable for immediate bone regeneration due to its rapid initial regeneration, while Bio-Oss provides long-term support, ideal for maintaining implant stability over a longer period of time. The results highlight the importance of selecting appropriate bone replacement materials depending on the clinical scenario to improve patient outcomes after dental implant placement.",10.3390/jcm13164638
+1116,Article,Event-Triggered Adaptive Fuzzy Control for Strict-Feedback Nonlinear FOSs Subjected to Finite-Time Full-State Constraints,"In this article, an event-triggered adaptive fuzzy finite-time dynamic surface control (DSC) is presented for a class of strict-feedback nonlinear fractional-order systems (FOSs) with full-state constraints. The fuzzy logic systems (FLSs) are employed to approximate uncertain nonlinear functions in the backstepping process, the dynamic surface method is applied to overcome the inherent computational complexity from the virtual controller and its fractional-order derivative, and the barrier Lyapunov function (BLF) is used to handle the full-state constraints. By introducing the finite-time stability criteria from fractional-order Lyapunov method, it is verified that the tracking error converges to a small neighborhood near the zero and the full-state constraints are satisfied within a predetermined finite time. Moreover, reducing the communication burden can be guaranteed without the occurrence of Zeno behavior, and the example is given to demonstrate the effectiveness of the proposed controller.",10.3390/fractalfract8030160
+1117,InProceedings,Everyone for Themselves? A Qualitative Study about Individual Security Setups of Open Source Software Contributors,"To increase open-source software supply chain security, protecting the development environment of contributors against attacks is crucial. For example, contributors must protect authentication credentials for software repositories, code-signing keys, and their systems from malware. Previous incidents illustrated that open-source contributors struggle with protecting their development environment. In contrast to companies, open-source software projects cannot easily enforce security guidelines for development environments. Instead, contributors' security setups are likely heterogeneous regarding chosen technologies and strategies. To the best of our knowledge, we perform the first in-depth qualitative investigation of the security of open-source software contributors' individual security setups, their motivation, decision-making, and sentiments, and the potential impact on open-source software supply chain security. Therefore, we conduct 20 semi-structured interviews with a diverse set of experienced contributors to critical open-source software projects. Overall, we find that contributors have a generally high affinity for security. However, security practices are rarely discussed in the community or enforced by projects. Furthermore, we see a strong influence of social mechanisms, such as trust, respect, or politeness, further impeding the sharing of security knowledge and best practices. We conclude our work with a discussion of the impact of our findings on open-source software and supply chain security, and make recommendations for the open-source software community.",10.1109/SP54263.2024.00214

+1119,Article,FOSS: Towards Fine-Grained Unknown Class Detection Against the Open-Set Attack Spectrum With Variable Legitimate Traffic,"Anomaly-based network intrusion detection systems (NIDSs) are essential for ensuring cybersecurity. However, the security communities realize some limitations when they put most existing proposals into practice. The challenges are mainly concerned with (i) fine-grained unknown attack detection and (ii) ever-changing legitimate traffic adaptation. To tackle these problem, we present three key design norms. The core idea is to construct a model to split the data distribution hyperplane and leverage the concept of isolation, as well as advance the incremental model update. We utilize the isolation tree as the backbone to design our model, named FOSS, to echo back three norms. By analyzing the popular dataset of network intrusion traces, we show that FOSS significantly outperforms the state-of-the-art methods. Further, we perform an initial deployment of FOSS by working with the Internet Service Provider (ISP) to detect distributed denial of service (DDoS) attacks. With real-world tests and manual analysis, we demonstrate the effectiveness of FOSS to identify previously-unseen attacks in a fine-grained manner.",10.1109/TNET.2024.3413789
+1120,Article,Financing A Free-for-All: Crowdfunding Open-Source Software,"This paper examines whether open-source software (OSS) provides unique advantages in the entrepreneurial crowdfunding context. The economic model for new ventures with business plans centered on OSS is often counterintuitive to early-stage investors. On the one hand, the non-restrictive OSS approach reduces the barriers to widespread product adoption and collaboration; on the other, OSS is essentially a public good, creating a scenario where anyone can appropriate value from the product without compensating its creators. As such, an OSS approach can dissuade investors primarily concerned with appropriating value for themselves, making it difficult for early-stage OSS ventures to attract investors. However, the rapid rise of crowdfunding has created a communally minded investor base that might instead find OSS projects enticing. We theorize that the attributes of OSS projects align with the communal expectations of crowdfunding investors and thus create supportive environments for OSS-based ventures. We illustrate this alignment through the community-based resource mobilization framework and suggest that the OSS approach yields greater investor trust, leading to superior financing outcomes. Our mixed methods approach blends archival analyses of Kickstarter data with a constructive replication through a randomized experiment, providing consistent support that an OSS approach can be advantageous in the crowdfunding context. Can rewards-based crowdfunding open new doors to finance open-source software (OSS) projects? Our research suggests that crowdfunding backers are more likely to support OSS projects because they are perceived as more trustworthy. While the economic principles of OSS can be counterintuitive, OSS promotes widespread product adoption and collaboration. This allows anyone to benefit from OSS. Our research builds on the notion that crowdfunding, much like OSS, is a communal endeavor. We leverage data from the rewards-based crowdfunding platform Kickstarter.com and a controlled experiment, finding a connection between projects that espouse the OSS approach and crowdfunding success. The culmination of the two studies advances knowledge of the unique preferences of crowdfunding backers and suggests that the crowdfunding context is fertile ground to bring new insights into OSS-focused start-ups.",10.1007/s11187-023-00867-y

Meanwhile, a finite-time adaptive dynamic surface control (DSC) approach based on backstepping technology and approximation principle of radial basis function neural network (RBFNN) is developed. To overcome the problem of inherent computational complexity, a fractional-order filter is applied to approach the virtual controller and its fractional-order derivative in each step of the backstepping procedure. The barrier Lyapunov function (BLF) is employed to handle the state constraints, and finite-time stability criteria on the basis of fractional-order Lyapunov method are introduced to prove the finite-time convergence of the tracking error into a small region around the origin. It is shown that all the solutions of the closed-loop system are bounded, while the state constraints are satisfied within a predetermined finite time. Finally, two examples are provided to demonstrate the effectiveness of the presented control scheme.",10.1080/23307706.2024.2381652

Nowadays, it is becoming challenging to procure bone legally, resulting in medical students' inadequacy of bone. Plaster -of -Paris or resin bone models sold on the market are less detailed than real bones. Aims and objectives This study aims to create a three-dimensional (3D)-printed human bone model with free, open-source software and fused deposition modelling (FDM) 3D printers, compare its accuracy with the original bones and validate it with a textbook description. Methods Scapula and hip bone models were produced using open-source software 3D Slicer from computed tomography (CT) data from the ``New Mexico Decedent Image Database{''}. After automated segmentation, bones were edited manually with tools in a 3D Slicer (https://www.slicer.org/) and Meshmixer software (Autodesk Inc., San Rafael, California, United States) and 3D bone models were printed using polylactic (PLA) filament. Results and discussions 3D digital models of both bones were successfully created with the maximum possible accuracy with an FDM 3D printer. A 3D digital replica of the scapula obtained after segmentation retained most anatomical features except for the glenoid cavity, as the head of the humerus obscured the glenoid cavity. The 3D digital skeleton of the hip bone retained all anatomical features except articulating surfaces, such as the acetabulum and auricular surface ilium, which were obscured by the head of the femur and sacrum. A few morphological features of both bones differed from the original dry bone, and a few finer details were unclear in the iliac fossa and ischium. After manual editing and post -processing, the final physical model obtained has all the features. Conclusions We conclude that it is possible to produce anatomically accurate models with the greatest possible resemblance and accuracy to the original bones using free and open-source data with an FDM 3D printer.",10.7759/cureus.60212

Although multitude of studies have provided effective models for OSS sustainability, their practical implications have been lacking because most identified features are not amenable to direct tuning by developers (e.g., levels of communication, number of commits per project). In this paper, we report on preliminary work toward making models more actionable based on evidence-based findings from prior research. Given a set of identified features of interest to OSS project sustainability, we performed a comprehensive literature review related to those features to uncover practical, evidence-based advice, which we call Researched Actionables (ReACTs). The ReACTs are practical advice with specific steps, found in prior work to associate with tangible results. Starting from a set of sustainability-related features, this study contributes 105 ReACTs to the SE community by analyzing 186 published articles. Moreover, this study introduces a newly developed tool (ReACTive) designed to enhance the exploration of ReACTs through visualization across various facets of the OSS ecosystem.

The analyses reveal that individuals from different backgrounds have distinct migration patterns. Individuals who grew up in rural areas but moved to cities have significantly different political preferences than individuals who grew up and still reside in rural areas. The results indicate that KD and SD mainly attract rural voters, while L, MP, M, and V primarily attract urban residents. Individuals with certain characteristics are likelier to choose specific types of residential areas and have political preferences typical for their area of choice. This suggests a geographical sorting of different groups into rural and urban areas and a geographic political divergence (in support of SD, KD) and convergence (in support of C, S, L, M) in party preferences.",NA

However, the governance of an OSS producing DAO should match the particularities of OSS production while also overcoming the existing challenges of decentralized governance. The existing decentralized governance frameworks do not include all the governance activities of OSS projects. Therefore, this study presents a governance framework for DAOs that produce OSS. The framework is built upon a total of 34 articles on DAO and OSS governance. The framework was evaluated in three leading DAOs that produce OSS. The evaluation underscores the significance of the framework and proves the potential of the systematic categorization of governance mechanisms.

Mentoring allows contributors to improve their technical skills and learn about the protocols and cultural norms of the project. However, mentoring has its challenges: mentors sometimes feel unappreciated, and mentees may have mismatched interests or lack interpersonal skills. Existing research has investigated the different challenges of mentoring in different OSS contexts, but we lack a holistic understanding. Objective: A comprehensive understanding of the current practices and challenges of mentoring in OSS is needed to implement appropriate strategies to facilitate mentoring. Method: This study presents a systematic literature review investigating how literature has characterized mentoring practices in OSS, including their challenges and the strategies to mitigate them. We retrieved 232 studies from four digital libraries. Out of these, 21 were primary studies. Using this, we performed backward and author snowballing, adding another 27 studies. We conducted a completeness check by reviewing the references of the 4 most relevant primary studies, which resulted in us adding 1 additional study. We then conducted a full-text review and evaluated the studies using a set of criteria; as a result, 10 papers were excluded. We then employed an open-coding approach to analyze, aggregate, and synthesize the selected studies. Results: We reviewed 39 studies to investigate the different facets of mentoring in OSS, encompassing motivations, goals, channels, and contributor dynamics. We then identified 13 challenges associated with mentoring in OSS, which fall into three categories: social, process, and technical. We also present a quick-reference strategy catalog to map these strategies to challenges for mitigation.

+1137,Article,How are decisions made in open source software communities? - Uncovering rationale from python email repositories,"Group decision-making (GDM) processes shape the evolution of open source software (OSS) products, thus playing an important role in the governance of open source software communities. While these GDM processes have attracted the attention of researchers, the rationale behind decisions, that is, how decisions are made that enhance the OSS, have not received much attention. This work bridges this gap by extracting these rationales from a large open source repository comprising 1.55 million emails available in Python development archives. This work makes a methodological contribution by presenting a heuristics-based rationale extraction system called Rationale Miner that employs information retrieval, natural language processing, and heuristics-based techniques. Using these techniques, it extracts the rationale behind specific decisions (for example, whether a new module was added based on core developer consensus or a benevolent dictator's pronouncement). This work unearths 11 such rationales behind decisions in the Python community and thus makes a knowledge contribution. It also analyzes the prevalence of these rationales across all PEPs and three sub-types of PEPs: Process, Informational, and Standard Track PEPs. The effectiveness of our contributions has been positively evaluated using quantitative and qualitative approaches (e.g., comparison against baselines for rationale identification showed up to 47\\% improvement in the most conservative case, and feedback from the Python steering committee showed the accurate identification of rationales respectively). The approach proposed in this work can be used and extended to discover the rationale behind decisions that remain hidden in communication repositories of other OSS projects, which will make the decision-making (DM) process transparent to stakeholders and encourage decision-makers to be more accountable.",10.1002/smr.2526

The research highlights the highly transient behavior of fast flood flows, particularly when carrying debris, and their effect on bridge superstructures. Utilizing a Digital Elevation Model to extract cross-sectional and elevation data, the research examined 23 profiles over 800 m of the river. The results indicate that the maximum allowable water depth in front of the bridge is 4.73 m, with a Manning's coefficient of 0.03 and a longitudinal slope of 9 m per kilometer. Therefore, a novel method to identify the risks through HEC-RAS modeling significantly improves the conservation of masonry bridges by providing precise topographical and hydrological data for accurate simulations. Moreover, the detailed information obtained from LIDAR and UAV photogrammetry about the bridge's materials and structures can be incorporated into the conservation models. This comprehensive approach ensures that preservation efforts are not only addressing the immediate hydrodynamic threats but are also informed by a thorough understanding of the bridge's structural and material conditions.

Such SCA tools depend on a vulnerability database to know affected libraries of each vulnerability. However, it is labor-intensive and error prone for a security team to manually maintain the vulnerability database. While several approaches adopt extreme multi-label learning to predict affected libraries for vulnerabilities, they are practically ineffective due to the limited library labels and the unawareness of ecosystems.To address these problems, we first conduct an empirical study to assess the quality of two fields, i.e., affected libraries and their ecosystems, for four vulnerability databases. Our study reveals notable inconsistency and inaccuracy in these two fields. Then, we propose Holmes to identify affected libraries and their ecosystems for vulnerabilities via a learning-to-rank technique. The key idea of Holmes is to gather various evidences about affected libraries and their ecosystems from multiple sources, and learn to rank a pool of libraries based on their relevance to evidences.

Due to this reason, this research focused on the preparation of a biomaterial sheet using natural material and with a low-cost method. Firstly, a silk floss sheet (SFS) was prepared using the waste cocoons by degumming, opening up, and finishing process. Afterward, the biodegradable ss-cyclodextrin (ss-CD) was successfully grafted onto SFS using citric acid (CA) through the pad-dry-cure method. Then, Iranian herbal essential oils (Shirazi thyme and Dermaneh) were loaded into the cavities of ss-CD molecules. Then, the samples were investigated using SEM and elemental analysis. The inclusion complex formed between the herbal essential oils and the ss-CD cavity (HEOs- ss-CD) was also evaluated using high-sensitivity analyses of FTIR, XRD, and UV-Visible. Furthermore, free HEOs and HEOs- ss-CD inclusion complex were assessed for their ability to scavenge the 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) radical, and the results showed that the HEOs- ss-CD inclusion complex can improve antioxidant activity compared to the free HEOs. The antimicrobial activity of the prepared SFS was also determined against Staphylococcus aureus, Escherichia coli, and Candida albicans by quality and quantity methods. The results have shown that the modified SFS has a high resistance against the mentioned microorganisms. In addition, the SFS had no negative effect on the viability of the Vero cell line.

+1145,Article,Incorporation of small extracellular vesicles in PEG/HA-Bio-Oss hydrogel composite scaffold for bone regeneration,"Stem cell derived small extracellular vesicles (sEVs) have emerged as promising nanomaterials for the repair of bone defects. However, low retention of sEVs affects their therapeutic effects. Clinically used natural substitute inorganic bovine bone mineral (Bio-Oss) bone powder lacks high compactibility and efficient osteo-inductivity that limit its clinical application in repairing large bone defects. In this study, a poly ethylene glycol/hyaluronic acid (PEG/HA) hydrogel was used to stabilize Bio-Oss and incorporate rat bone marrow stem cell-derived sEVs (rBMSCs-sEVs) to engineer a PEG/HA-Bio-Oss (PEG/HA-Bio) composite scaffold. Encapsulation and sustained release of sEVs in hydrogel scaffold can enhance the retention of sEVs in targeted area, achieving long-lasting repair effect. Meanwhile, synergistic administration of sEVs and Bio-Oss in cranial defect can improve therapeutic effects. The PEG/HA-Bio composite scaffold showed good mechanical properties and biocompatibility, supporting the growth of rBMSCs. Furthermore, sEVs enhanced in vitro cell proliferation and osteogenic differentiation of rBMSCs. Implantation of sEVs/PEG/HA-Bio in rat cranial defect model promoted in vivo bone regeneration, suggesting the great potential of sEVs/PEG/HA-Bio composite scaffold for bone repair and regeneration. Overall, this work provides a strategy of combining hydrogel composite scaffold systems and stem cell-derived sEVs for the application of tissue engineering repair.",10.1088/1748-605X/ad7e6c

However, there exist various OSS licenses in the community, written in a formal language, which are typically long and complicated to understand. In this paper, we conducted a 661-participants online survey to investigate the perspectives and practices of developers towards OSS licenses. The user study revealed an indeed need for an automated tool to facilitate license understanding. Motivated by the user study and the fast growth of licenses in the community, we propose the first study towards automated license summarization. Specifically, we released the first high quality text summarization dataset and designed two tasks, i.e., license text summarization (LTS), aiming at generating a relatively short summary for an arbitrary license, and license term classification (LTC), focusing on the attitude inference towards a predefined set of key license terms (e.g., Distribute). Aiming at the two tasks, we present LiSum, a multi-task learning method to help developers overcome the obstacles of understanding OSS licenses. Comprehensive experiments demonstrated that the proposed jointly training objective boosted the performance on both tasks, surpassing state-of-the-art baselines with gains of at least 5 points w.r.t.

The results show that the sensor is capable of providing the joint angle with appreciable accuracy, with a maximum error of about 4 degrees, falling within the mean error of the validation tools, and a larger error only for angles at the extremes of the analyzed range of motion.

However, due to the complexity of geometry description and the absence of a reliable 3D contact algorithm, the development of 3D-NMM still has a long-time challenge. In this study, an opensource software named MEG3D to generate the numerical model for 3D-NMM is developed.

The combination of information from various modalities can contribute to a comprehensive understanding of tissue specimens, aiding in more accurate diagnoses, and improved research insights. Multimodal image registration in histology samples presents a significant challenge due to the inherent differences in characteristics and the need for tailored optimization algorithms for each modality.ResultsWe developed MMIR a cloud-based system for multimodal histological image registration, which consists of three main modules: a project manager, an algorithm manager, and an image visualization system.ConclusionOur software solution aims to simplify image registration tasks with a user-friendly approach.

+1158,Article,MSProfileR: An Open-Source Software for Quality Control of Matrix-Assisted Laser Desorption Ionization-Time of Flight Spectra,"In the early 2000s, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) emerged as a performant and relevant tool for identifying micro-organisms. Since then, it has become practically essential for identifying bacteria in microbiological diagnostic laboratories. In the last decade, it was successfully applied for arthropod identification, allowing researchers to distinguish vectors from non-vectors of infectious diseases. However, identification failures are not rare, hampering its wide use. Failure is generally attributed either to the absence of respective counter species MS spectra in the database or to the insufficient quality of query MS spectra (i.e., lower intensity and diversity of MS peaks detected). To avoid matching errors due to non-compliant spectra, the development of a strategy for detecting and excluding outlier MS profiles became compulsory. To this end, we created MSProfileR, an R package leading to a bioinformatics tool through a simple installation, integrating a control quality system of MS spectra and an analysis pipeline including peak detection and MS spectra comparisons. MSProfileR can also add metadata concerning the sample that the spectra are derived from. MSProfileR has been developed in the R environment and offers a user-friendly web interface using the R Shiny framework. It is available on Microsoft Windows as a web browser application by simple navigation using the link of the package on Github v.3.10.0. MSProfileR is therefore accessible to non-computer specialists and is freely available to the scientific community. We evaluated MSProfileR using two datasets including exclusively MS spectra from arthropods. In addition to coherent sample classification, outlier MS spectra were detected in each dataset confirming the value of MSProfileR.",10.3390/informatics11020039
+1160,Article,MYRIAM: Open-Source Software to Estimate Torque Variations Associated With Plate-Motion Temporal Changes,"Tectonic plate motions are a prime constraint on lithosphere dynamics and on the torques acting upon plates. Researchers typically test hypotheses on the controlling torques via forward computer models, which allow accepting or rejecting hypotheses on the basis of the fit of model-output plate velocities to kinematic reconstructions. Such models typically require a significant amount of input information (e.g., tectonic boundaries, structure of the lithosphere, lateral variations of rheology, among others) to appropriately model the tectonic system, and obtain sufficiently-realistic realizations of plate motions. Alternatively, the inverse problem approach takes the difference between the plate torque-balance at two distinct moments in time. This results in an equation in which (a) torques that have not varied through time are canceled out and (b) torques that instead have varied through time are linked to the resulting plate-motion change through a term that accounts for the plate shape and the rheology of the underlying asthenosphere. This approach sacrifices the capability to describe the different individual forces/torques acting upon a plate. Instead, it focuses on determining torque temporal variations, which significantly reduces the amount of input knowledge required. In this technical note we introduce MYRIAM, an open-source software that implements such an inverse approach. MYRIAM takes plate-motion temporal changes, and outputs an estimate of the torque variation required upon a plate to generate the input kinematic change. MYRIAM is released as an open-source repository hosted at GitHub, complete with source code and executable files for Windows and Unix-based operating systems. Plain Language Summary The outermost layer of the Earth, known as the lithosphere, is fragmented into plates that are in motion relative to each other. Through geological history, the motion of tectonic plates did not remain steady, and in fact important changes are now known to have occurred relatively fast, within a few million years. By virtue of Newton's laws of motion, these changes are all necessarily caused by the variation in one or more forces acting upon the plates, and therefore disrupt their force balance. Changing the motion of a plate is not an easy feat-for plates it requires overcoming the frictional resistance exerted by the underlying asthenosphere, a low-viscosity layer beneath the plates. The resulting motion change will depend on (a) the mechanical properties of the asthenosphere and (b) the amount of plate surface interacting with said asthenosphere (i.e., the basal area of the plate). All these considerations are taken into account by MYRIAM, an open-source, computationally-inexpensive software that estimates the force/torque variations required to produce a given change of plate motion.",10.1029/2023GC011095
+1161,InProceedings,Measuring the Effects of Stack Overflow Code Snippet Evolution on Open-Source Software Security,"This paper assesses the effects of Stack Overflow code snippet evolution on the security of open-source projects. Users on Stack Overflow actively revise posted code snippets, sometimes addressing bugs and vulnerabilities. Accordingly, developers that reuse code from Stack Overflow should treat it like any other evolving code dependency and be vigilant about updates. It is unclear whether developers are doing so, to what extent outdated code snippets from Stack Overflow are present in GitHub projects, and whether developers miss security-relevant updates to reused snippets. To shed light on those questions, we devised a method to 1) detect outdated code snippets versions from 1.5M Stack Overflow snippets in 11,479 popular GitHub projects and 2) detect security-relevant updates to those Stack Overflow code snippets not reflected in those GitHub projects. Our results show that developers did not update dependent code snippets when those evolved on Stack Overflow. We found that 2,405 code snippet versions reused in 2,109 GitHub projects were outdated, with 43 projects missing fixes to bugs and vulnerabilities on Stack Overflow. Those 43 projects containing outdated, insecure snippets were forked on average 1,085 times (max. 16,121), indicating that our results are likely a lower bound for affected code bases. An important insight from our work is that treating Stack Overflow code as purely static code impedes holistic solutions to the problem of copying insecure code from Stack Overflow. Instead, our results suggest that developers need tools that continuously monitor Stack Overflow for security warnings and code fixes for reused code snippets and not only warn during copy-pasting.",10.1109/SP54263.2024.00022

With the aim to investigate the trustworthiness of the Pull Request (PR) process, the common model of collaborative development in OSS community, we exploit process mining to identify and analyze the normal and anomalous patterns of PR processes, and propose our approach to identifying anomalies from both control-flow and semantic aspects, and then to analyze and synthesize the root causes of the identified anomalies. We analyze 17531 PRs of 18 OSS projects on GitHub, extracting 26 root causes of control-flow anomalies and 19 root causes of semantic anomalies. We find that most PRs can hardly contain both semantic anomalies and control-flow anomalies, and the internal custom rules in projects may be the key causes for the identified anomalous PRs. We further discover and analyze the patterns of normal PR processes. We find that PRs in the non-fork model (42%) are far more likely than the fork model (5%) to bypass the review process, indicating a higher potential risk. Besides, we analyzed nine poisoned projects whose PR practices were indeed worse. Given the complex and diverse PR processes in OSS community, the proposed approach can help identify and understand not only anomalous PRs but also normal PRs, which offers early risk indications of suspicious incidents (such as poisoning) to OSS supply chain.",10.1145/3597503.3639196

Constructing simulations to assess the effect of the penetration of distributed generation on electrical distribution networks has become of great importance for Distribution Network Operators (DNOs). This paper proposes a simulation strategy based on open-source platforms and the integration of scripting tools for the rapid modeling of large-scale electrical distribution circuits with distributed renewable generation. The implementation is based on the adaptation of a tool called QGIS2OpenDSS, which creates OpenDSS distribution network models directly from an open-source geographic information system, QGIS. The plugin's capabilities are demonstrated using a real distribution feeder with more than 60\\% penetration of renewable generation based on photovoltaic systems. These simulations are carried out using real data from a circuit provided by a DNO in the Dominican Republic, which is used to demonstrate how this approach provides a more accessible and flexible way to simulate and assess the effect of Distributed Energy Resources (DERs) in medium voltage (MV) and low voltage (LV) networks, enabling utilities to evaluate system performance and identify potential issues. The integration of this open-source tool within the DNO software stack enables users to apply it according to specific project needs, enhancing their capability to analyze and manage high DER penetration levels, aiding in better planning, operation, and decision-making processes related to renewable energy projects.",10.3390/en17122925
+1164,Article,Modeling interconnected social and technical risks in open source software ecosystems,"Open source software ecosystems consist of thousands of interdependent libraries, which users can combine to great effect. Recent work has pointed out two kinds of risks in these systems: that technical problems like bugs and vulnerabilities can spread through dependency links, and that relatively few developers are responsible for maintaining even the most widely used libraries. However, a more holistic diagnosis of systemic risk in software ecosystem should consider how these social and technical sources of risk interact and amplify one another. Motivated by the observation that the same individuals maintain several libraries within dependency networks, we present a methodological framework to measure risk in software ecosystems as a function of both dependencies and developers. In our models, a library’s chance of failure increases as its developers leave and as its upstream dependencies fail. We apply our method to data from the Rust ecosystem, highlighting several systemically important libraries that are overlooked when only considering technical dependencies. We compare potential interventions, seeking better ways to deploy limited developer resources with a view to improving overall ecosystem health and software supply chain resilience.",10.1177/26339137241231912

However, the focus has primarily been on intra-project clones. Our work comprehensively investigates cross-project code clones in open-source software for Internet of Things (IoT) systems across multiple programming languages. This work addresses the prevalence of cross-project code clones in IoT systems and their impact on software maintainability. We collected 122 IoT system repositories in nine languages from GitHub and grouped them according to their primary functionality in IoT systems. We used MSCCD, a multilingual code clone detector to detect Type-3 code clones for each group. The results show that cross-project clones exist in more than 30\\% of the projects, particularly in communication-related functionalities. We tracked the historical evolution of these clones and classified them according to the revision history and changing trend of similarity. The results show that 95\\% cross-project clones are untouched. Moreover, clones with decreasing similarities were over 72\\%. Therefore, the same clone detector may no longer detect these clones. We also investigated whether these cross-project code clones lead to defect propagation by analyzing the commit message to determine the commits that fixed a defect. We identified nine defect propagation instances, of which seven remain unfixed. Our work contributes to understanding cross-project code clones, highlighting the importance of automated clone management tools for improving the quality and security of IoT system software to mitigate the risks associated with unresolved defects and inconsistencies in IoT software development.",10.1109/ACCESS.2024.3506013

These experiments are executed by training the model under observation with varying configurations. Since executing a typical training run can take days even on proven acceleration fabrics such as Graphics Processing Units (GPU), properly managing training data, avoiding human error in configuration preparations and securing the repeatability of the experiments are of utmost importance. In this paper, we present two open source software tools that aim to achieve these goals, namely, a Dataset Manager (DatumAid) tool and a Training Automation Manager (OrchesTrain) tool. DatumAid is a software tool that integrates with Computer Vision Annotation Tool (CVAT) to facilitate the management of annotated datasets. By adding additional functionality, DatumAid allows users to filter labeled data, manipulate datasets, and export datasets for training purposes. The tool adopts a simple code structure while providing flexibility to users through configuration files.

+1176,Article,"Open-Source Software Defined Networking Controllers: State-of-the-Art, Challenges and Solutions for Future Network Providers","Software Defined Networking (SDN) is programmable by separation of forwarding control through the centralization of the controller. The controller plays the role of the `brain' that dictates the intelligent part of SDN technology. Various versions of SDN controllers exist as a response to the diverse demands and functions expected of them. There are several SDN controllers available in the open market besides a large number of commercial controllers; some are developed to meet carrier-grade service levels and one of the recent trends in open-source SDN controllers is the Open Network Operating System (ONOS). This paper presents a comparative study between open source SDN controllers, which are known as Network Controller Platform (NOX), Python-based Network Controller (POX), component-based SDN framework (Ryu), Java-based OpenFlow controller (Floodlight), OpenDayLight (ODL) and ONOS. The discussion is further extended into ONOS architecture, as well as, the evolution of ONOS controllers. This article will review use cases based on ONOS controllers in several application deployments. Moreover, the opportunities and challenges of open source SDN controllers will be discussed, exploring carrier- grade ONOS for future real-world deployments, ONOS unique features and identifying the suitable choice of SDN controller for service providers. In addition, we attempt to provide answers to several critical questions relating to the implications of the open-source nature of SDN controllers regarding vendor lock-in, interoperability, and standards compliance, Similarly, real-world use cases of organizations using open-source SDN are highlighted and how the open-source community contributes to the development of SDN controllers. Furthermore, challenges faced by open-source projects, and considerations when choosing an open-source SDN controller are underscored. Then the role of Artificial Intelligence (AI) and Machine Learning (ML) in the evolution of open-source SDN controllers in light of recent research is indicated. In addition, the challenges and limitations associated with deploying open-source SDN controllers in production networks, how can they be mitigated, and finally how open- source SDN controllers handle network security and ensure that network configurations and policies are robust and resilient are presented. Potential opportunities and challenges for future Open SDN deployment are outlined to conclude the article.",10.32604/cmc.2024.047009

We are dependent on software controlled by global technology giants. The dependence on commonly used services and platforms provided by Microsoft, Google or Amazon must be removed to achieve digital sovereignty. Open-source software has been readily available for a long time, but studies looking into excluding all proprietary software from working life are scarce. This paper investigates the feasibility of replacing proprietary software as a step towards digital sovereignty. The ability to self-host services is key to ensuring independence, and the ability to verify software code is key to ensuring integrity. Therefore open-source code and transparency are transient properties for sovereign software. We present problems by mapping the problematic software used by teachers, researchers and student assistants at Arcada UAS with a varied set of requirements on the digital tools of their daily lives. We research alternatives and deploy a suite of software compatible with EU policies on digital sovereignty. We rely on many services offered by tech giants in our professional lives. There are several open-source software suites that can be self-hosted and that have permissive licenses for business use. Extensive technical knowledge is required for the deployment of software. Most daily tasks can be accomplished by using sovereign software, although not all needs of the test group were met. Companies can deploy sovereign software for most daily tasks, reducing dependency on tech giants. However, software adoption was low. Arcadas IT-support does not host, enforce or endorse the usage of sovereign software. Public code repositories enable independent code verification, in contrast to proprietary software. Some software cannot be easily replaced, and digital habits are hard to change.",10.1007/978-3-031-61891-8\\_10

This paper investigates the contribution of Free/Libre Open-Source Software (FLOSS) towards fair, and conflict-free practices through promoting collaboration, transparency, and resource accessibility. Our study investigates how the adoption of decentralized online social networks (DOSN) like Mastodon (microblogging) and PeerTube (video sharing), which operate on the ActivityPub protocol, contributes to sustainable practices within the electronics sector by fostering a federated universe (Fediverse). It is demonstrated how FLOSS, in the form of Alternative Mobile Operating Systems (AMOS) including Android open-source custom ROMs or mobile Linux systems, gain traction due to enhanced privacy protection, improved usability through tracker-free software and alternative app stores, and adherence to EU directives on the right to self-repair. As AMOS mature for everyday use, they attract consumers, thereby contributing towards sustainable electronics development. Furthermore, the Fediverse's Application Programming Interfaces (APIs) enable seamless information exchange between instances, allowing for nuanced moderation that safeguards user privacy.

This surge in unmanned aerial vehicles has increased attention towards monitoring tasks in vital areas, such as urban spaces for security, surveillance or Internet of the Things applications. In this sense, we propose an open-source software-in-the-loop approach that integrates the complete navigation experience, accounting for potential wind-related effects, and providing realistic 3D modeling of scenarios encompassing open spaces in city landscapes. Our work introduces a wind perturbation estimation strategy, which models the wind effect as an external force along the Zaxis based on altitude variations from real flights. Validation was conducted using real data flights with a quadrotor aiding the navigation with Ardupilot and QgroundControl as a ground station. To complement the experiments we include a small test with a fixed-wing plane to asses the software-in-the-loop accuracy on larger trajectories. Results demonstrate successful tracking of altitude variations, yielding errors below 10\\% relative to the home position in experiments with average trajectory lengths of 150 m in two scenarios in Quito. The software-in-the-loop simulation aimed to replicate wind conditions specific to the date and time of real data acquisition, providing a platform to emulate possible improvements and assess UAV performance before deployment in actual missions. This research not only contributes to the optimization of monitoring capabilities but also serves as a valuable tool for assessing UAV missions in diverse and dynamic environments.",10.1109/ICUAS60882.2024.10556936
+1182,Article,Open-source software for respiratory rate estimation using single-lead electrocardiograms,"Respiratory rate (RR) is a critical vital sign used to assess pulmonary function. Currently, RR estimating instrumentation is specialized and bulky, therefore unsuitable for remote health monitoring. Previously, RR was estimated using proprietary software that extract surface electrocardiogram (ECG) waveform features obtained at several thoracic locations. However, developing a non-proprietary method that uses minimal ECG leads, generally available from mobile cardiac monitors is highly desirable. Here, we introduce an open-source and well-documented Python-based algorithm that estimates RR requiring only single-stream ECG signals. The algorithm was first developed using ECGs from awake, spontaneously breathing adult human subjects. The algorithm-estimated RRs exhibited close linear correlation to the subjects' true RR values demonstrating an R-2 of 0.9092 and root mean square error of 2.2 bpm. The algorithm robustness was then tested using ECGs generated by the ischemic hearts of anesthetized, mechanically ventilated sheep. Although the ECG waveforms during ischemia exhibited severe morphologic changes, the algorithm-determined RRs exhibited high fidelity with a resolution of 1 bpm, an absolute error of 0.07 +/- 0.07 bpm, and a relative error of 0.67 +/- 0.64\\%. This optimized Python-based RR estimation technique will likely be widely adapted for remote lung function assessment in patients with cardiopulmonary disease.",10.1038/s41598-023-50470-0

To date, no SRGM can be applied and implemented in all software development and testing environments. Therefore, how to choose an appropriate SRGM for software reliability evaluation in the current software development and testing environment is an important practical issue. In this study, we proposed a weighted Grey relational analysis method to select the optimal SRGMs, including closed- and open-source SRGMs, as well as perfect and imperfect debugging SRGMs. To effectively validate the effectiveness of the proposed method, we used 12 SRGMs, 11 model evaluation criteria, and 2 successive versions of open-source software fault datasets.

As the ability of the variometric approach to detect short-term dynamic behaviors in real-time mode in applications such as Global Navigation Satellite Systems (GNSS)-seismology and structural health monitoring is demonstrated, the demand for open-source VA software is increasing. However, open-source software that is capable of VA processing in real-time mode based on single- and dual-frequency multi-GNSS observations is scarce. In view of this fact, we have developed an open-source VA processing software called PPPH-VA that can evaluate single- and dual-frequency multi-GNSS observations in real-time mode. PPPH-VA is developed in the MATLAB environment, and it can simultaneously process GPS, GLONASS, Galileo, BeiDou-2, and BeiDou-3 data with the VA technique in real-time mode, employing both single- and dual-frequency observations. We evaluated PPPH-VA using shake table experiments based on real data, and the results demonstrate that it provides high accuracy in terms of detection of dynamic displacements.

The software runs on 64-bit Windows computers. This software allows the extraction of phenotypic traits on a per-microplot basis from orthomosaic and digital surface model (DSM) images generated by Structure-from-Motion/Multi-View-Stereo (SfM-MVS) tools. Moreover, there is no need to acquire skills in geographical information system (GIS) or programming languages for image analysis. Three use cases illustrated the software's functionality. The first involved monitoring the growth of sugar beet varieties in an experimental field using an unmanned aerial vehicle (UAV), where differences among varieties were detected through estimates of crop height, coverage, and volume index. Second, mixed varieties of potato crops were estimated using a UAV and varietal differences were observed from the estimated phenotypic traits. A strong correlation was observed between the manually measured crop height and UAV-estimated crop height. Finally, using a multicamera array attached to a tractor, the height, coverage, and volume index of the 3 potato varieties were precisely estimated.

While there exists a growing body of literature on cisgender women's under-representation in OSS, the experiences of contributors from other marginalized groups are comparatively absent from the literature. Such is the case for trans contributors, a historically influential group in OSS. In this study, we interviewed 21 trans participants to understand and represent their experiences in the OSS literature.

Consequently, software engineers are adopting pre-trained models (PTMs) for their downstream applications. The dynamics of the PTM supply chain remain largely unexplored, signaling a clear need for structured datasets that document not only the metadata but also the subsequent applications of these models. Without such data, the MSR community cannot comprehensively understand the impact of PTM adoption and reuse. This paper presents the PeaTMOSS dataset, which comprises metadata for 281,638 PTMs and detailed snapshots for all PTMs with over 50 monthly downloads (14,296 PTMs), along with 28,575 open-source software repositories from GitHub that utilize these models. Additionally, the dataset includes 44,337 mappings from 15,129 downstream GitHub repositories to the 2,530 PTMs they use. To enhance the dataset's comprehensiveness, we developed prompts for a large language model to automatically extract model metadata, including the model's training datasets, parameters, and evaluation metrics. Our analysis of this dataset provides the first summary statistics for the PTM supply chain, showing the trend of PTM development and common shortcomings of PTM package documentation. Our example application reveals inconsistencies in software licenses across PTMs and their dependent projects. PeaTMOSS lays the foundation for future research, offering rich opportunities to investigate the PTM supply chain.

+1194,InProceedings,Planetary Localization in GPS-Deprived Environments with Open-Source Software and Commercial-Off-the-Shelf Components,"Autonomous unmanned vehicles can perform detailed surveys of planetary surfaces but it is imperative to establish a method for global localization to effectively explore these areas. The absence of GPS in extraplanetary environments prevents surface vehicles from knowing their exact location, which raises the need for an alternative positioning system. Traditional methods, such as visual odometry cross-referenced with digital elevation maps, are limited by their dependence on human input and pre-existing space infrastructure. This paper outlines and characterizes a global position determination algorithm intended for planetary surface vehicles in GPS-denied environments without any prior knowledge. The localization algorithm receives images of the stars from a visible camera and tilt measurements from an inclinometer, derives star locations and a gravity vector, and combines these signals to generate an onboard position determinant. This paper contributes (i) the first open-source planetary global localization algorithm based on stars, (ii) a sensor suite design derived of solely commercial-off-the-shelf (COTS) components, and (iii) an unprecedented physical experiment and characterization from this algorithm on Earth's surface. The resulting position determinant is on average 100km from the testing location, consistent across various time and surface inclines. This result is compared to theoretical performance, state-of-the-art sensor performance, and other global localization methods. This achieved determinant error offers a starting point toward localization improvement with more capable sensors and the incorporation of multiple historical determinants for state estimation.",10.1109/iSpaRo60631.2024.10688190

+1197,Article,Pyrolysis study of moxa floss with different storage years using online photoionization mass spectrometry,"The pyrolysis behaviors of moxa floss with 5-9 storage years were investigated by thermogravimetry (TG) and online synchrotron radiation photoionization mass spectrometry. The online fragment-free mass spectra of moxa floss pyrolysis products were obtained within 300-800degree celsius and characterized as hydrocarbons, nitrogenous and oxygenated compounds. The results indicate that pyrolysis temperature plays a leading role in the lowmolecular-weight product distribution, while the storage year has secondary effects. Controlling the pyrolysis temperature in a lower range (<650degree celsius) can effectively reduce the generation of benzene, toluene and other harmful substances. Aromatics could be released from the break of large molecules with aromatic structures and formed from the aromatization of small unstructured compounds at high temperatures. At the temperature lower than 400 degree celsius, short-year samples exhibit a higher intensity of oxygenated compounds. However, with the increase of storage years, nitrogenous heterocyclics such as pyrrole and pyridine are preferably formed at higher temperatures. In addition, increasing the storage year of moxa floss leads the TG curve to exhibit a lower maximum mass loss rate. These results will enrich the understanding of the storage year effect on the beneficial oxygencontaining components generation and the release of harmful components in the moxa floss pyrolysis.",10.1016/j.jaap.2023.106271

Our software implements the digital generation of various types of error signals, from an analog input through the application of loop filters of high complexity and real-time gain adjustment for multiple analog output signals, including different algorithms for resonance search, lock acquisition sequences, and in-loop gain optimization. Furthermore, all necessary diagnostic instruments, such as an oscilloscope, a network analyzer, and a spectrum analyzer, are integrated into our software. Apart from providing a quickly scalable, automatic feedback controller, the lock performance that can be achieved by using PyRPL with imperfect equipment, such as piezoelectric transducers and noisy amplifiers, is better than the one achievable with standard analog controllers due to the higher complexity of implementable filters and possibilities of nonlinear operations in the FPGA. This drastically reduces the cost of added complexity when introducing additional feedback loops to an experiment. The open-source character also distinguishes PyRPL from commercial solutions, as it allows users to customize functionalities at various levels, ranging from the easy integration of PyRPL-based feedback controllers into existing setups to the modification of the FPGA functionality.

+1199,Article,Quality evaluation meta-model for open-source software: multi-method validation study,"In recent years, open-source software (OSS) has attracted increasing attention due to its easy accessibility via cloud repositories, voluntary community, no vendor lock-in, and low total cost of ownership. In turn, specifying and evaluating OSS quality has become a significant challenge for OSS adoption in organizations that are inclined to use them. Although many OSS quality models have been proposed in the literature, the dynamic and diverse nature of OSS has caused these models to be heterogeneous in terms of structure and content. This has adversely affected the standardization of evaluations and led to the evaluation results obtained from different OSS quality models for the same purpose being incomparable and sometimes unreliable. Therefore, in this study, a meta-model for OSS quality (OSS-QMM), which employs a unified structure from existing quality models and enables the derivation of homogeneous models, has been proposed. For this purpose, a systematic and laborious effort has been spent via a step-based meta-model creation process including review-and-revise iterations. In order to validate the OSS-QMM, case study and expert opinion methods have been applied to answer three research questions (RQs) targeted to investigate practical applicability, results comparability, and effectiveness of using the meta-model. Multiple and embedded case study designs have been employed for evaluating three real ERP systems, and 20 subject matter experts have been interviewed during the validation process. The results of multi-faceted empirical studies have indicated that the OSS-QMM has addressed solving problems in OSS quality evaluation and its adoption with high degrees of confidence.",10.1007/s11219-023-09658-w
+1201,Article,Quantitative Analysis of Fish Morphology Through Landmark and Outline-based Geometric Morphometrics with Free Software,"Morphology underpins key biological and evolutionary processes that remain elusive. This is in part due to the limitations in robustly and quantitatively analyzing shapes within and between groups in an unbiased and high- throughput manner. Geometric morphometrics (GM) has emerged as a widely employed technique for studying shape variation in biology and evolution. This study presents a comprehensive workflow for conducting geometric morphometric analysis of fish morphology. The step-by-step manual provides detailed instructions for using popular free software, such as the TPS series, MorphoJ, ImageJ, and R, to carry out generalized Procrustes analysis (GPA), principal component analysis (PCA), discriminant function analysis (DFA), canonical variate analysis (CVA), mean shape analysis, and thin plate spline analysis (TPS). The Momocs package in R is specifically utilized for in-depth analysis of fish outlines. In addition, selected functions from the dplyr package are used to assist in the analysis. The full process of fish outline analysis is covered, including extracting outline coordinates, converting and scaling data, defining landmarks, creating data objects, analyzing outline differences, and visualizing results. In conclusion, the current protocol compiles a detailed method for evaluating fish shape variation based on landmarks and outlines. As the field of GM continues to evolve and related software develops rapidly, the limitations associated with morphological analysis of fish are expected to decrease. Interoperable data formats and analytical methods may facilitate the sharing of morphological data and help resolve related scientific problems. The convenience of this protocol allows for fast and effective morphological analysis. Furthermore, this detailed protocol could be adapted to assess image-based differences across a broader range of species or to analyze morphological data of the same species from different origins.",10.21769/BioProtoc.5087

+1204,Article,Reading Comprehension on Screen: A Free Software Educational Proposal,"The increasing digitalization of social life has substantially modified everyday practices, including teaching -learning processes. The aim of this article is to analyze digital reading in a free software educational community. The experience was carried out on April 22, 2023 in the city of Cordoba (Argentina) with children of different ages in the Latin American Festival of Free Software Installation. Based on a qualitative methodology, with the incorporation of some ethnographic tools, data were collected from the reading situations observed in the intervention. We used the following theoretical foundations: ludic narratives and video games, digital reading in a hybrid context (coexistence of paper and screen) and free software in education. The data collected were analyzed with grounded theory procedures to construct the following categories of analysis of the digital reading comprehension of children: literal comprehension, inferential comprehension, inferential comprehension of literary elements and comprehension of the ludic structure and. We conclude that reading on screen mediated by free software shows a cognitive complexity that allows the critical review of the influence of GAFAMs in the educational community and that benefits the strengthening of the cultural mesh.",10.15366/reice2024.22.2.008
+1205,Article,Sherlock in OSS: A Novel Approach of Content-Based Searching in Object Storage System,"Cloud-based Object Storage Systems (OSS) are known for their scalability, durability, availability, and concurrency. However, there is a noticable vaccum in open-source OSS for a straightforward way for users and administrators to conduct data searches within object storage without fully utilizing the cloud infrastructure. In our research, we present Sherlock, a novel Content-Based Searching (CoBS) framework. Sherlock enhances search capabilities by using extra information from images and documents, incorporating this information into an Elasticsearch-powered database to enable content-driven searches. The framework operates through a two-stage process. First, it classifies the incoming data by type, directing images to an object detection model and processing documents for keyword extraction. Then, Elasticsearch catalogs the extracted data, facilitating searches based on content. The effectiveness of our searches is largely dependent on the precision of these models, which we improve by training them on large-scale datasets: the Microsoft COCO Dataset for multimedia content and the SemEval2017 Dataset for text documents. We further test our system's performance by integrating it with the open-source OSS, OpenStack Swift, and conducting real-world experiments with image uploads to evaluate how our model performs within Swift's object storage environments.",10.1109/ACCESS.2024.3401074
+1206,InProceedings,Shock! Quantifying the Impact of Core Developers' Dropout on the Productivity of OSS Projects,"Open Source Software (OSS) projects play a critical role in the digital infrastructure of companies and services provided to millions of people. Given their importance, understanding the resilience of OSS projects is paramount. A primary reason for OSS project failure is the shock caused by the dropout of a core developer, which can jeopardize productivity and project survival. Using a difference-in-differences (DiD) analysis, this study investigates the repercussions of this shock on the productivity of 8,234 developers identified among 9,573 OSS GitHub projects. Our findings reveal the indirect impact of the core developer's dropout. The remaining developers experienced a 20% productivity drop. This observation is troubling because it suggests that the shock might push other developers to drop out, putting the collaboration structure of the project at risk. Also, projects with higher productivity before the shock experienced a larger drop-down after the shock. This points to a tradeoff between productivity and resilience, i.e., the ability of OSS projects to recover from the dropout of a core developer. Our findings underscore the importance of a balanced approach in OSS project management, harmonizing productivity goals with resilience considerations.",10.1145/3589335.3651559
+1208,InProceedings,Simulating Imager-Based Sensor Networks for Structural Dynamics Applications with Open-Source Software,"Video-based structural dynamics are becoming increasingly popular on account of their high spatial resolution and relatively low costs. These techniques show promise for applications such as structural health monitoring. However, video-based approaches to measuring structural dynamics are not as sensitive as on-contact sensor-based techniques. Furthermore, because video-based techniques involve capturing a 2D perspective projection of the 3D environment, there is an added complication in extracting calibrated quantitative measurements from these systems. In many applications, it would be advantageous to deploy networks, or arrays of imagers for monitoring large-scale infrastructure from different perspectives. Often, computer vision techniques, such as multi-view stereo, benefit from knowledge of the position and orientation of the cameras. Unfortunately, accurately knowing this information can lead to increased setup costs. Furthermore, it is not always clear what arrangement of cameras would be sufficient for any given infrastructure monitoring applications. In addition, the performance of arrays of imagers is affected by factors such as lighting conditions and weather. There may also be significant restrictions on the physical locations where imagers are allowed to be placed. For these reasons, it is advantageous to have tools to aid in the design and development of imager-based sensor networks for structural dynamics applications. In this work, we demonstrate the use of open-source computer graphics software for simulating the behavior of imagers observing dynamic structures. We demonstrate the ability to use these tools to plan the deployment of imager-based sensor networks to rapidly test and develop algorithms and techniques for video-based structural dynamics.",10.1007/978-3-031-68901-7\\_4
+1209,Article,Singing Ability Assessment: Development and validation of a singing test based on item response theory and a general open-source software environment for singing data,"We describe the development of the Singing Ability Assessment (SAA) open-source test environment. The SAA captures and scores different aspects of human singing ability and melodic memory in the context of item response theory. Taking perspectives from both melodic recall and singing accuracy literature, we present results from two online experiments (N = 247; N = 910). On-the-fly audio transcription is produced via a probabilistic algorithm and scored via latent variable approaches. Measures of the ability to sing long notes indicate a three-dimensional principal components analysis solution representing pitch accuracy, pitch volatility and changes in pitch stability (proportion variance explained: 35\\%; 33\\%; 32\\%). For melody singing, a mixed-effects model uses features of melodic structure (e.g., tonality, melody length) to predict overall sung melodic recall performance via a composite score {[}R(2)c = .42; R(2)m = .16]. Additionally, two separate mixed-effects models were constructed to explain performance in singing back melodies in a rhythmic {[}R(2)c = .42; R(2)m = .13] and an arhythmic {[}R(2)c = .38; R(2)m = .11] condition. Results showed that the yielded SAA melodic scores are significantly associated with previously described measures of singing accuracy, the long note singing accuracy measures, demographic variables, and features of participants' hardware setup. Consequently, we release five R packages which facilitate deploying melodic stimuli online and in laboratory contexts, constructing audio production tests, transcribing audio in the R environment, and deploying the test elements and their supporting models. These are published as open-source, easy to access, and flexible to adapt.",10.3758/s13428-023-02188-0

Each of these quality assurance practices have been studied in depth in isolation, but there is a clear knowledge gap when it comes to our understanding of how these approaches are being used in conjunction, or not. In our study, we broadly investigate whether and how these quality assurance approaches are being used in conjunction in the development of 1454 popular open source software projects on GitHub. Our study indicates that typically projects do not follow all quality assurance practices together with high intensity. In fact, we only observe weak correlation among some quality assurance practices. In general, our study provides a deeper understanding of how existing quality assurance approaches are currently being used in Java-based open source software development. Besides, we specifically zoom in on the more mature projects in our dataset, and generally we observe that more mature projects are more intense in their application of the quality assurance practices, with more focus on their ASAT usage, and code reviewing, but no strong change in their CI usage.",10.1002/spe.3321

The study aims to assist a community of OSS developers in quantifying the product's reliability. This research proposes reliability growth models for OSS by incorporating dynamicity in the debugging process. For this, stochastic differential equation-based analytical models are developed to represent the instantaneous rate of error generation. The fault introduction rate is modeled using exponential and Erlang distribution functions. The empirical applications of the proposed methodology are verified using the real-life failure data of the Open Source Software projects, GNU Network Object Model Environment, and Eclipse. A soft computing technique, Genetic Algorithm, is applied to estimate model parameters. Cross-validation is also performed to examine the forecasting efficacy of the model. The predictive power of the developed models is compared with various benchmark studies. The data analysis is conducted using the R statistical computing software. The results demonstrate the proposed models' efficacy in parameter estimation and predictive performance. In addition, the optimal release time policy based on the proposed mathematical models is presented by formulating the optimization model that intends to minimize the total cost of software development under reliability constraints. The numerical illustration and sensitivity analysis exhibit the proposed problem's practical significance.

We acquired GPR profiles all throughout the area of the internal part of the basement and the outer retaining wall part. The pieces of equipment used were SIR 4000 and a HS 350 MHz center frequency antenna. The data presented a good and consistent signal. High resolution subsoil images of up to 3m in depth of the area below the parking lots were generated through the analysis of information derived from the processing and interpretation of the data. All of these were compared with information from geotechnical and topographic studies of the area. The results obtained show that the trees' roots are causing scour due to a drying effect of the subsoil, which caused damage to the slab in the parking lot and on the retaining wall.",10.15446/esrj.v28n3.97305

+1217,Article,Survivability Prediction of Open Source Software with Polynomial Regression,"In modern software development, OSS (Open Source Software) has become a crucial element. However, if OSS have few contributors and are lacking in maintenance activities, such as bug fixes, are used, it can lead to significant costs and resource allocation due to maintenance discontinuation. Since OSS are developed by a diverse group of contributors, the consistency of their involvement may vary, making continuous support and maintenance unpredictable. Therefore, it is necessary to identify the status of each OSS to avoid increased maintenance costs when selecting OSS for use. To address these issues, we use polynomial regression to predict trends in bug-fixing activities and evaluate the survivability of OSS accordingly. We predict the trend of bug-fixing activities in OSS, using factors such as popularity, number of contributors, and code complexity. A lower trend value indicates more vigorous activity. In this paper, we conduct data collection and extraction, generating model, and model testing and evaluation to predict survivability using these data. After collecting data through various tools, the models of different degrees are generated using K-fold cross-validation. The model with the highest performance is selected based on the RMSE (Root Mean Squared Error) and RSE (Residual Standard Error). Then, the chosen model is employed to predict the survivability of OSS and compare it with actual outcomes. This method is experimented with on OSS used in the KakaoTalk commercial messenger app. As a result, several OSS are predicted to have low survivability, and among them, five are analyzed. It is observed that, in reality, activities such as delayed or discontinued release updates occurred. These findings can support OSS users in selecting OSS for cost-saving purposes and alert OSS administrators to the need for solutions to ensure project survival.",10.3390/app14072812

For the OSS projects to stay sustainable, i.e., viable and maintained over time without interruption or weakening, maintenance labor requires an underlying infrastructure to be supported and secured. Aims: Using the construct of human infrastructure, our study aims to investigate how maintenance labor can be supported and secured to enable the creation and maintenance of sustainable OSS projects, viewed from the maintainers’ perspective. Method: In our exploration, we interviewed ten maintainers from nine well-adopted OSS projects. We coded the data in two steps using investigator-triangulation. Results: We constructed a framework of infrastructure design that provide insight for OSS projects in the design of their human infrastructure. The framework specifically highlight the importance of human factors, e.g., securing a work-life balance and proactively managing social pressure, toxicity, and diversity. We also note both differences and overlaps in how the infrastructure needs to support and secure maintenance labor from maintainers and the wider OSS community, respectively. Funding is specifically highlighted as an important enabler for both types of resources. Conclusions: The study contributes to the qualitative understanding of the importance, sensitivity, and risk for depletion of the maintenance labor required to build and maintain healthy OSS projects.

While past research has proposed strategies for the sustainability of the scientific software or general OSS communities in isolation, it remains unclear when the two scenarios are merged if these approaches are directly applicable to developing scientific OSS. In this research, we propose to investigate the unique challenges in sustaining the scientific OSS ecosystems. We first conduct a case study to empirically understand the interdisciplinary team's collaboration in scientific OSS ecosystems and identify the collaboration challenges.

This paper proposes a system security assessment method that integrates the risk relationships of open source software (OSS). Firstly, an OSS risk propagation relationship graph is constructed, and the Fuzzy Analytic Hierarchy Process (FAHP)-entropy weight method is adopted to allocate weights to the weakness assessment indicators of OSS, thereby improving the accuracy of quantifying OSS propagation risks. Then, on the attack graph, the analysis of threat values to host nodes and the probability of successful attack paths are optimized from three perspectives: vulnerabilities, OSSSC, and hosts. Experimental results demonstrate that this method, by combining open source risk factors and conducting multi-dimensional analysis, can more effectively assess the security threats faced by systems, providing a more accurate basis for security defense.",10.1109/NaNA63151.2024.00011
+1223,Article,THE ENTRAINMENT OF TASK ALLOCATION AND RELEASE CYCLES IN OPEN SOURCE SOFTWARE DEVELOPMENT,"In this study we identify a process of ``entrainment{''} around open source software (OSS) development release cycles to capture patterns of self -organized task allocation among developers. We conducted an abductive, computationally intensive study of eight OSS projects, using relational event modeling to analyze 1,169,489 actions covering 93 major software releases. The process of entrainment that we identify involves three task allocation mechanisms: (1) developer -issue inertia, (2) developer contribution frequency, and (3) issue popularity. Our analysis demonstrates that these mechanisms and the phases of the release cycle entrain each other. Before a major release, developers engage in a concentrated mobilization phase, whereby they democratize development activity and increasingly allocate community contributions to the set of issues related to the release. After a major release, the extended cleanup phase garners a greater share of development work from recently highly active developers and dilutes the activity of these developers across a wider range of issues. Our theorizing suggests that major releases constitute important events around which OSS communities self -organize and we characterize how this occurs. Our research contributes to theorizing on organizing in OSS communities by explaining how selforganizing task allocation interacts with release cycles through the mechanism of entrainment. We also contribute to the literature on entrainment by showing how it may unfold in the context of online peer production communities such as OSS.",10.25300/MISQ/2023/16789

In many urban areas (or agroecosystems), the practice of illegal waste disposing by commercial activities, by abandoning it in the countryside rather than spending economic resources to ensure correct disposal, is widespread. This causes an accumulation of waste in these areas (which can also be protected natural areas), which are then also set on fire to reduce their volume. Obviously, the repercussions of such actions are many. The burning of waste releases contaminants into the environment such as dioxins, polychlorinated biphenyls and furans, and deposits other elements on the soil, such as heavy metals, which, by leaching and percolating, contaminate water resources such as rivers and aquifers. The main objective is the design and implementation of monitoring programs against specific illicit activities that take into account territorial peculiarities. This advanced approach leverages AI and GIS environments to interpret environmental states, providing an understanding of ongoing phenomena. The methodology used is based on the implementation of mathematical and AI algorithms, integrated into a GIS environment to address even large-scale environmental issues, improving the spatial and temporal precision of the analyses and allowing the customization of monitoring programs in urban and peri-urban environments based on territorial characteristics. The results of the application of the methodology show the percentages of the different types of waste found in the agroecosystems of the study area and the degree of concentration, allowing the identification of similar areas with greater criticality. Subsequently, through network and nearest neighbour analysis, it is possible to start targeted checks.",10.3390/urbansci8010021

Best practices suggest employing UX Capability Maturity Models (UXCMMs), which often specify an evolutionary plateau toward developing a UX-matured system and quantify organizational UX maturity into maturity levels ranging from no or ad hoc improvement to integrated continuous improvement. Numerous generically developed UXCMMs exist. However, none is created for the FOSS community, and less information is available to support their perfect match. Thus, raise suspicions if they have proper UX maturity influencing factors (UXMIFs) for the FOSS community or measure the right thing. The FOSS community differs from traditional software-developing communities and may have different dynamics and UXMIFs, necessitating unique and new methodologies for their discovery. This study, therefore, aims to identify the FOSS community's UXMIFs and evaluate the community's knowledge of UX maturity-related concepts. Its findings may help future researchers, practitioners, and other FOSS developers to develop UXCMMs exclusive to the FOSS community. The study's design is both qualitative and quantitative. It adopted a systematic literature review, interviews, fuzzy Delphi Method, and thematic analysis to collect and analyze data and present the findings. The study's sample included sixty-two active FOSS projects, fifteen FOSS stakeholders, and twelve UX experts.

+1228,Article,The vital role of community in open source software development: A framework for assessment and ranking,"Open source software (OSS) follows a software development paradigm whereby self-motivated volunteers scattered all around the globe contribute to the development in the form of code, documentation, feedback, feature recommendations, bug reporting, and bug resolution. These volunteers, commonly referred to as OSS project community, serve as the foundation of the OSS project, fostering its creation and sustenance and providing long-term support. The quality and sustainability of the OSS project is reliant upon the development and structure of the self-governing community. When a business organization plans to acquire an OSS solution, it not only takes into consideration the factors such as reliability, security, and scalability but also attaches significant importance to the likelihood of the OSS project being maintained and supported in the future so that it can rely on it as a stable and secure technology solution. Modern cloud-based software hosting platforms, such as GitHub, offer a range of options for automatically and freely accessing the complete development history of millions of OSS projects. This easy availability of detailed development history has enabled researchers to analyze and draw quantitative and scientific inferences about the quality of an OSS project which generally involves assessing three aspects, namely, software product, development process, and project community. With focus on project community part, a Framework for Assessment and Ranking of OSS Community is being presented in the current research work, following a detailed examination of the largest source code hosting and project collaboration platform, GitHub. Technique for Order of Preference by Similarity to Ideal Solution from Multi-Criteria Decision-Making toolkit has been utilized for assessing the quality of the project community. The framework has been validated by applying it on nine OSS projects and comparing the results with the outcomes obtained through an existing OSS evaluation methodology. The comparative analysis demonstrated that the proposed framework aligns with the aforementioned evaluation methodology while offering an opportunity for in-depth analysis on the dynamics of volunteer communities, which is lacking in previous evaluation methods. These insights can prove valuable for both potential adopters and project maintainers, aiding them in making informed strategic decisions. Framework for Project Community Assessment and Ranking follows a phased approach where first phase involves OSS project identification, second phase defines assessment criteria, in third phase data is fetched, stored and metrics are computed; and the last phase involves final Quality Assessment and Ranking. The framework will aid both corporate entities and individual practitioners in identifying an open source project with a robust volunteer community capable of producing a product of exceptional quality.image",10.1002/smr.2643

Nonwoven mats with a 1-inch thickness were produced by uniformly arranging milkweed fibers within a mold. Various quantities of fiber were employed to obtain nonwoven mats with a fiber content ranging from 5 to 35 kg/m3. Thermal conductivity and thermal diffusivity were measured across diverse relative humidity levels and temperatures. Simultaneously, milkweed floss samples were exposed to identical environmental conditions to assess the moisture regain and specific heat capacities of the fiber. The specific heat capacity of milkweed and thermal conductivity of the nonwovens exhibited a linear increase with temperature. The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content. The thermal insulation properties of the nonwovens remained partially stable below 30\\% relative humidity but substantially deteriorated at higher levels. The nonwovens exhibited optimal thermal insulation properties at a fiber content between 20 and 25 kg/m3.

+1234,InProceedings,Towards Robust Detection of Open Source Software Supply Chain Poisoning Attacks in Industry Environments,"The exponential growth of open-source package ecosystems, particularly NPM and PyPI, has led to an alarming increase in software supply chain poisoning attacks. Existing static analysis methods struggle with high false positive rates and are easily thwarted by obfuscation and dynamic code execution techniques. While dynamic analysis approaches offer improvements, they often suffer from capturing non-package behaviors and employing simplistic testing strategies that fail to trigger sophisticated malicious behaviors. To address these challenges, we present OSCAR, a robust dynamic code poisoning detection pipeline for NPM and PyPI ecosystems. OSCAR fully executes packages in a sandbox environment, employs fuzz testing on exported functions and classes, and implements aspect-based behavior monitoring with tailored API hook points. We evaluate OSCAR against six existing tools using a comprehensive benchmark dataset of real-world malicious and benign packages. OSCAR achieves an F1 score of 0.95 in NPM and 0.91 in PyPI, confirming that OSCAR is as effective as the current state-of-the-art technologies. Furthermore, for benign packages exhibiting characteristics typical of malicious packages, OSCAR reduces the false positive rate by an average of 32.06% in NPM (from 34.63% to 2.57%) and 39.87% in PyPI (from 41.10% to 1.23%), compared to other tools, significantly reducing the workload of manual reviews in real-world deployments. In cooperation with Ant Group, a leading financial technology company, we have deployed OSCAR on its NPM and PyPI mirrors since January 2023, identifying 10,404 malicious NPM packages and 1,235 malicious PyPI packages over 18 months. This work not only bridges the gap between academic research and industrial application in code poisoning detection but also provides a robust and practical solution that has been thoroughly tested in a real-world industrial setting.",10.1145/3691620.3695262

We integrate the results of a qualitative survey and a big data analysis to understand developer perceptions of corporate engagement and its association with gender and geographic diversity. In the qualitative component, we collected responses from 64 FLOSS contributors to elicit their perspectives on corporate engagement. In the quantitative component, we analyzed GitHub data from 38 projects and 9,990 contributors to investigate differences in participation and diversity based on corporate engagement. We find that contributors vary across dimensions that can inform diversity interventions: stances toward corporations and orientation towards individual/collective benefits. Our results suggest that corporate engagement may limit a project's contributor base and geographic diversity. Yet, organizations subsidizing FLOSS have opportunities to increase access to projects which would benefit diversity. This research serves to identify individual and organizational factors which may harm and help diversity initiatives.",10.1016/j.jss.2024.112163

However, the few open-source packages available for processing of spectral images are limited in scope. Here, we present VISION, a stand-alone software based on Python for spectral analysis with improved applicability. In addition to classical intensity-based analysis, our software can batch-process multidimensional images with an advanced single-cell segmentation capability and apply userdefined mathematical operations on spectra to calculate biophysical and metabolic parameters of single cells. VISION allows for 3D and temporal mapping of properties such as membrane fluidity and mitochondrial potential. We demonstrate the broad applicability of VISION by applying it to study the effect of various drugs on cellular biophysical properties. the correlation between membrane fluidity and mitochondrial potential, protein distribution in cell-cell contacts and properties of nanodomains in cell-derived vesicles.

In recent years, this phenomenon has increasingly manifested in virtual collaborative spaces such as open-source software communities because of the advancement in the use of online technologies and the heightened need for distance work. However, it is still unclear which underlying mechanisms foster collaboration in these spaces. By using the Linux kernel open-source software community as a case study, we analyze data from the linux-pci@vger.kernel.org mailing list to model the influence of proximity on the likelihood of collaboration between individuals. Our dataset is composed of 10,513 message replies to the PCI mailing list posted by its 654 active members in the years 2013 to 2015. Our results show that geographical proximity does not have a direct impact on collaboration, while organizational features defined by institutional and organizational proximity do significantly affect collaboration. Cognitive and social proximity also significantly, and positively, affects collaboration, but these relationships show an inverted u-shaped form. Our results confirm the need to develop specific theorizing about virtual spaces, as they present unique features when compared to traditional physical environments.",10.1111/radm.12599
+1241,InProceedings,Vision: Identifying Affected Library Versions for Open Source Software Vulnerabilities,"Vulnerability reports play a crucial role in mitigating open-source software risks. Typically, the vulnerability report contains affected versions of a software. However, despite the validation by security expert who discovers and vendors who review, the affected versions are not always accurate. Especially, the complexity of maintaining its accuracy increases significantly when dealing with multiple versions and their differences. Several advances have been made to identify affected versions. However, they still face limitations. First, some existing approaches identify affected versions based on repository-hosting platforms (i.e., GitHub), but these versions are not always consistent with those in package registries (i.e., Maven). Second, existing approaches fail to distinguish the importance of different vulnerable methods and patched statements in face of vulnerabilities with multiple methods and change hunks.To address these problems, this paper proposes a novel approach, Vision, to accurately identify affected library versions (ALVs) for vulnerabilities. Vision uses library versions from the package registry as inputs. To distinguish the importance of vulnerable methods and patched statements, Vision performs critical method selection and critical statement selection to prioritize important changes and their context. Furthermore, the vulnerability signature is represented by weighted inter-procedural program dependency graphs that incorporate critical methods and statements. Vision determines ALVs based on the similarities between these weighted graphs. Our evaluation demonstrates that Vision outperforms state-of-the-art approaches, achieving a precision of 0.91 and a recall of 0.94. Additionally, our evaluation shows the practical usefulness of Vision in correcting affected versions in existing vulnerability databases.",10.1145/3691620.3695516

Therefore, in this paper, we propose a two-phase based approach for JAVA OSS vulnerability analysis. To reduce underreporting, we construct a comprehensive third-party library and vulnerability association database; to avoid false positives, first, we use a static analysis method to extract the structure-aware call graph (SACG) of oss and locate the information of the vulnerability functions; second, we compare the similarity between the OSS vulnerability functions and the pre-patch and post-patch functions based on the vulnerability patches to determine the existence of the patches in the OSS, and then verify the OSS vulnerability information. We evaluate the method on a dataset of 7 open source projects and 167 vulnerability information, and the F1 value of the method is 0.779, which is higher than the currently available SOTA tools.",10.1145/3677182.3677315

However, this expansion has also brought significant security challenges, particularly introducing and propagating software vulnerabilities. Despite the use of machine learning and formal methods to tackle these issues, there remains a notable gap in comprehensive surveys that summarize and analyze both Vulnerability Detection (VD) and Security Patch Detection (SPD) in OSS. This article seeks to bridge this gap through an extensive survey that evaluates 127 technical studies published between 2014 and 2023, structured around the Vulnerability-Patch lifecycle. We begin by delineating the six critical events that constitute the Vulnerability-Patch lifecycle, leading to an in-depth exploration of the Vulnerability-Patch ecosystem. We then systematically review the databases commonly used in VD and SPD, and analyze their characteristics. Subsequently, we examine existing VD methods, focusing on traditional and deep learning based approaches. Additionally, we organize current security patch identification methods by kernel type and discuss techniques for detecting the presence of security patches. Based on our comprehensive review, we identify open research questions and propose future research directions that merit further exploration.",10.1145/3694782

Henze ``Das Flog der Medusa{''} ({''}The Raft of Medusa{''}), often seen as an example of Henze's political engagement. The author of the article concludes that the oratorio was recognized as a political composition in large part due to the accompanying circumstances of its creation and premiere, but not based on the original idea and its realisation. The author demonstrate ``Das Flog der Medusa{''} like a example of the protest music as a direction that exposes not only fascism, but also any form of social inequality, violence against the person. The study of the features of choral style of ``Das Flog der Medusa{''} reveals parallels in the textural structure between Henze's oratorio and Nono's works of the 1950s ({''}La victoire de Guernica{''}, ``Il canto sospeso{''}, ``Intolleranza 1960{''}). The use of political text resources, the operation of individual syllables and phonemes of a literary text, work with multilingual verbal rows, the active use of diagonal texture - all this brings together the choral works of two contemporaries. At the same time, Henze's composition also reflected the searches in the field of vocal timbre, characteristic of other composers of Darmstadt Summer Course - the use of various modifications of speech singing ( Sprech- gesang ), the latest techniques of vocal articulation (vocal tremolo, prolongation of the anterolingual vibrant). All this together allows us to talk about Henz's oratorio as one of the most peculiar choral compositions of the late 1960s.",10.21638/spbu15.2024.102

However, the traditional powder materials were easy to agglomerate and settle, which led to the decrease of photocatalytic activity. The emergence of floating photocatalyst was important for the practical application of controlling harmful algal blooms. This study was based on the efficient powder photocatalyst bismuth oxide composite copper-metal organic framework (Bi2O3 @Cu-MOF), which was successfully loaded onto melamine sponge (MS) by sodium alginate immobilization to prepare a floating photocatalyst MS/Bi2O3 @Cu-MOF for the inactivation of Microcystis aeruginosa (M. aeruginosa) under visible light. When the capacity was 0.4 g (CA0.4), MS/Bi2O3 @Cu-MOF showed good photocatalytic activity, and the inactivation rate of M. aeruginosa reached 74.462\\% after 120 h. MS/Bi2O3 @Cu-MOF-CA0.4 showed a large specific surface area of 30.490 m2/g and an average pore size of 22.862 nm, belonging to mesoporous materials. After 120 h of treatment, the content of soluble protein in the MS/Bi2O3 @Cu-MOF-CA0.4 treatment group decreased to 0.365 mg/L, the content of chlorophyll a (chla) was 0.023 mg/L, the content of malondialdehyde (MDA) increased to 3.168 nmol/mgprot, and the contents of various antioxidant enzymes experienced drastic changes, first increasing and then decreasing. The photocatalytic process generated center dot OH and center dot O2-, which played key role in inactivating the algae cells.

+1248,Article,A Blockchain-Based Copyright Management Scheme for Open-Source Software and Hardware Designs,"Plagiarism in software code and hardware design threatens the open-source movement and the software and hardware industries. It is essential to differentiate between the unethical act of plagiarism and the legitimate use of open-source resources. Existing copyright protection measures, such as license design, inadequately address copyright ownership and protection issues. Furthermore, they fail to detect plagiarism methods for open-source hardware projects, such as circuit location modification. To address these challenges, this paper proposes a blockchain-based copyright management scheme, which introduces a general originality detection model based on community detection, extracting adjustable granularity digests from code and design files. These digests are stored on a peer-to-peer blockchain, enabling nodes to verify the originality via smart contracts. Additionally, the scheme improves the storage structure, protecting the rights of authors and contributors. Experimental results demonstrate the effectiveness and runtime efficiency of the proposed model in extracting digests for blockchain storage while maintaining verification accuracy. The scheme offers enhanced generality, practical performance, and suitability for distributed development and maintenance, with considerable implications for evidence gathering, fostering innovation and integrity.",10.26599/TST.2023.9010112
+1249,Article,A free method for patient-specific 3D-VR anatomical modeling for presurgical planning using DICOM images and open-source software,"Introduction: Surgeons commonly use cross sectional images to plan and prepare for surgical procedures. However, cognitively translating 2D images to surgical settings can be difficult and lead to sub-optimal resections. Lymph node dissection can be challenging due to the inability to locate small metastatic lesions, and their proximity to at-risk organ(s). 3D volume rendered (3D-VR) patient specific images can help to address these challenges. We created patient-specific 3D-VR images using freely available open-source programs. Methods: This study included patients part of the clinical trial NCT04857502. Patients received a PET/CT prior to radioguided surgery. 3D Slicer was used to segment anatomy of interest (organs and tumor lesion(s)). After segmentation, the data was exported as an .OBJ file with an accompanying .MTL file. Manipulation of the .MTL file to restore model properties to the .OBJ file, were completed and both files were uploaded into Autodesk Viewer. Surgeons then received an email link to access the finished 3D-VR model on their smartphone or laptop for peri-operative preparation and/or guidance. Results: The method was used in a series of 14 patients with prostate cancer undergoing pelvic lymph node dissection with PSMA-radioguided robotic surgery using pre-operative PSMA PET/CT images acquired on average 103 +/- 69 days prior to resection. The creation of the 3D-VR models was successfully conducted in all 14 cases. In all cases, the lesions identified on the pre-operative PET/CT imaging 3D-VR models were successfully removed during surgery. Conclusion: We created patient-specific anatomical 3D-VR models that the surgeons can use for pre-surgical planning and intraoperative tumor localization, by applying free, open-source software that could be used in any procedure requiring careful and strategical planning.",10.1016/j.ymeth.2025.02.006
+1250,Article,A methodology for assessing rooftop solar photovoltaic potential using GIS open-source software and the EROI constraint,"Energy consumption and carbon emissions are concentrated in cities, where 70 \\% of the global population is projected to live by 2050. Urban environments must therefore be at the heart of any global energy transition. Furthermore, land availability is a limiting factor for renewable deployment and rooftop PV thus offers a clear advantage. This research is based on the rooftop photovoltaic potential (RPVP) of the city of Vitoria-Gasteiz; its ultimate goal is to provide stakeholders with a useful and free tool to calculate a highly accurate RPVP (including different tilt and orientation angles, shadowing, temperature effect, energy return on energy investment (EROI) constraint and available surface area) and based exclusively on free-to-use and open-source software. The EROI constraint is a fundamental step towards the net energy analysis being integrated in the RPVP assessment. This paper is a contribution not only to the application of the EROI constraint, but also to the calculation of this indicator. Results improve on estimates commonly found in the literature. With an EROI > 5 (8.83 on average), Vitoria-Gasteiz has a RPVP of 473 GWh/year, able to supply 38 \\% of the total electricity consumption of the city and where 50 \\% of total rooftop area is suitable for PV. Therefore, the rooftop PV performance in Vitoria-Gasteiz is sufficiently good to provide the net energy required to sustain today's industrial societies. Additionally, this article provides valuable information, such as rooftop usability factors, and an overall reduction factor (CT), useful to extend RPVP assessment to larger areas using constant value methods.",10.1016/j.enbuild.2025.115401

For the solution of the two-dimensional flow field, the k-omega SST and Langtry-Menter Transition SST (gamma-(R) over tildee theta(t)) turbulence models were employed, while the Transition SST (gamma-(R) over tildee theta(t)) model was used for three-dimensional analyses. All simulations were time-dependent and solved using pimpleCentralFoam, a pressure-based, semi-implicit hybrid solver. The obtained data were compared with experimental results and examined in detail. The findings revealed that the hybrid solver used, combined with the Transition SST (gamma-(R) over tildee theta(t)) turbulence model-frequently preferred for modeling transition to turbulence-worked efficiently together and produced results closely aligned with experimental data. Additionally, the numerical method employed in this study offered a unique approach compared to other studies in the literature, demonstrating significant success in predicting the characteristics of pre-stall, stall, and post-stall conditions.",10.17341/gazimmfd.1156600
+1253,Article,"An alternative approach to code, store, and regenerate 3D data in dental medicine using open-source software: A scripting-based technique","Purpose: To develop a scripting-based technique for managing three-dimensional (3D) dental data and evaluate the regenerated standard tessellation language (STL) data in terms of file size, accuracy (trueness and precision), and processing time. Materials and Methods: Ten STL dental and maxillofacial models were obtained from various imaging technologies, including intraoral scanners, computer-aided design (CAD) software, and cone-beam computed tomography (CBCT), and saved as STL files. ChatGPT was used to generate Python scripts in Blender for mesh simplification and data compression, which were then saved as .py files. The models were regenerated from these scripts in Blender, and their accuracy was assessed using GOM Inspect software, comparing trueness and precision. Statistical analysis, including Kruskal-Wallis and Mann-Whitney tests, was conducted to evaluate differences in file sizes between the original, Python-generated, and regenerated STL files, with statistical analyses performed at a level of significance alpha=0.05. Results: The scripting-based technique was successfully utilized in ChatGPT to generate Python script code for accessing comprehensive data on STL models, utilizing Blender's scripting functionality. This approach enabled the generation, regeneration, and visualization of STL models, resulting in significantly smaller file sizes for both the Python script and regenerated STL files compared to the original STL files (p < 0.001). No significant differences in trueness were observed, with deviations ranging from 0.0 m to 6.8 mu m, and all regenerated STL models demonstrated perfect precision. Additionally, a proportional relationship was noted between the original STL file sizes and processing times. Conclusions: The scripting-based approach proved to be effective in coding, storing, and regenerating STL dental data with reduced file sizes and efficient processing times without compromising the accuracy. Clinical Significance: Various STL dental models of patients can be coded, stored, and regenerated to be used again within efficient processing time without affecting the accuracy.",10.1016/j.jdent.2025.105652
+1254,Article,Analyzing Key Features of Open Source Software Survivability with Random Forest,"Open source software (OSS) projects rely on voluntary contributions, but their long-term survivability depends on sustained community engagement and effective problem-solving. Survivability, critical for maintaining project quality and trustworthiness, is closely linked to issue activity, as unresolved issues reflect a decline in maintenance capacity and problem-solving ability. Thus, analyzing issue retention rates provides valuable insights into a project's health. This study evaluates OSS survivability by identifying the features that influence issue activity and analyzing their relationships with survivability. Kaplan-Meier survival analysis is employed to quantify issue activity and visualize trends in unresolved issue rates, providing a measure of project maintenance dynamics. A random forest model is used to examine the relationships between project features-such as popularity metrics, community engagement, code complexity, and project age-and issue retention rates. The results show that stars significantly reduce issue retention rates, with rates dropping from 0.62 to 0.52 as stars increase to 4000, while larger codebases, higher cyclomatic complexity, and older project age are associated with unresolved issue rates, rising by up to 15\\%. Forks also have a nonlinear impact, initially stabilizing retention rates but increasing unresolved issues as contributions became unmanageable. By identifying these critical factors and quantifying their impacts, this research offers actionable insights for OSS project managers to enhance project survivability and address key maintenance challenges, ensuring sustainable long-term success.",10.3390/app15020946
+1256,Article,Beyond Dependencies: The Role of Copy-Based Reuse in Open Source Software Development,"In Open Source Software, resources of any project are open for reuse by introducing dependencies or copying the resource itself. In contrast to dependency-based reuse, the infrastructure to systematically support copy-based reuse appears to be entirely missing. Our aim is to enable future research and tool development to increase efficiency and reduce the risks of copy-based reuse. We seek a better understanding of such reuse by measuring its prevalence and identifying factors affecting the propensity to reuse. To identify reused artifacts and trace their origins, our method exploits World of Code infrastructure. We begin with a set of theory-derived factors related to the propensity to reuse, sample instances of different reuse types, and survey developers to better understand their intentions. Our results indicate that copy-based reuse is common, with many developers being aware of it when writing code. The propensity for a file to be reused varies greatly among languages and between source code and binary files, consistently decreasing over time. Files introduced by popular projects are more likely to be reused, but at least half of reused resources originate from “small” and “medium” projects. Developers had various reasons for reuse but were generally positive about using a package manager.",10.1145/3715907

Funding for such databases is, however, insufficient and intermittent, resulting in the data being underutilized. While increased awareness of the importance of funding databases is important, it is practically necessary to find a more efficient way to build a community database. To meet the need for integrated database resources for various crop genomics, genetics, and breeding research communities, we have built five crop databases over the last decade using an open-source database platform and software.

This work introduces Dareplane, a modular and broad technology-agnostic open source software platform for brain-computer interface (BCI) research with an application focus on adaptive deep brain stimulation (aDBS). One difficulty for investigating control approaches for aDBS resides with the complex setups required for aDBS experiments, a challenge Dareplane tries to address. Approach. The key features of the platform are presented and the composition of modules into a full experimental setup is discussed in the context of a Python-based orchestration module. The performance of a typical experimental setup on Dareplane for aDBS is evaluated in three benchtop experiments, covering (a) an easy-to-replicate setup using an Arduino microcontroller, (b) a setup with hardware of an implantable pulse generator, and (c) a setup using an established and CE certified external neurostimulator. The full technical feasibility of the platform in the aDBS context is demonstrated in a first closed-loop session with externalized leads on a patient with Parkinson's disease receiving DBS treatment and further in a non-invasive BCI speller application using code-modulated visual evoked potential (c-VEP). Main results. The platform is implemented and open-source accessible on https://github.com/bsdlab/Dareplane. Benchtop results show that performance of the platform is sufficient for current aDBS latencies, and the platform could successfully be used in the aDBS experiment.

Free and open-source software (FOSS) presents a viable solution for facilitating the transfer of digital archives for permanent preservation. Despite the existence of FOSS policy in South Africa, the public sector has yet to fully use it to engage in the development and implementation of products for records management and archive preservation using open-source software. This study aims to explore the ingestion of digital archives into an approved long-term storage system through FOSS in South Africa with the view of developing a framework.Design/methodology/approachThe study adopted a qualitative research approach to collect data through interviews with purposively selected participants (records managers, archivists and IT officials) from national government departments that have implemented records management systems for digital curation of archives, as well as the National Archives and Records Services of South Africa (NARSSA), which regulates archives and records management, and the State Information Technology Agency, which regulates information technology in government.FindingsThe findings of the study suggest that the systematic transfer of digital materials from public entities to NARSSA, as required by statute, has not taken place.Research limitations/implicationsThe study specifically targeted national government departments that have implemented digital archives and records management systems. Consequently, perspectives from departments that have not implemented these solutions were excluded.Originality/valueA framework is proposed for the transfer of digital archives, using interoperable FOSS, from government agencies responsible for records management to NARSSA for archival preservation.

Herein, the fishery for Antarctic krill (Euphausia superba, Henceforth Krill) was used as a case study to develop the approach. Implementation of a sustainable management strategy for the krill fishery is complicated by a lack of regularly updated krill abundance data on spatiotemporal scales of the fishery. To increase krill biomass data availability, automatic echosounder data processing and swarm detection software was tested against traditional manual scrutinization with LSSS software and agreed with only minor offsets in estimated nautical area scattering coefficients. In addition to automatic processing and data transfer, Krillscan also has a graphical user interface to supervise automatic krill swarm detection. Echogram size can be compressed up to 100 times and raw data are processed faster than generated, thereby enabling near-real time analysis and data transfer.

LAMB leverages the capabilities of large language models and associated generative artificial intelligence technologies to create generative intelligent learning assistants that enhance educational experiences by providing personalized learning support based on clear directions and authoritative fonts of information. Key features of LAMB include its modular architecture, which supports prompt engineering, retrieval-augmented generation, and the creation of extensive knowledge bases from diverse educational content, including video sources. The development and deployment of LAMB were iteratively refined using a minimum viable product approach, exemplified by the learning assistant: ``Macroeconomics Study Coach,{''} which effectively integrated lecture transcriptions and other course materials to support student inquiries. Initial validations in various educational settings demonstrate the potential that learning assistants created with LAMB have to enhance teaching methodologies, increase student engagement, and provide personalized learning experiences. The system's usability, scalability, security, and interoperability with existing LMS platforms make it a robust solution for integrating artificial intelligence into educational environments. LAMB's open-source nature encourages collaboration and innovation among educators, researchers, and developers, fostering a community dedicated to advancing the role of artificial intelligence in education. This paper outlines the system architecture, implementation details, use cases, and the significant benefits and challenges encountered, offering valuable insights for future developments in artificial intelligence assistants for any sector.",10.1016/j.csi.2024.103940
+1265,Article,Multifaceted formal methods and their interdisciplinary role - From the cathedral of `components as coalgebras' to the HCI context and the open source software bazaar,"In this article we revisit the history of formal methods with a focus on important aspects that contribute to their interdisciplinary role. We consider: the variability of mathematical representation techniques on which the theoretical foundations of formal methods are based; formal methods multidisciplinarity; their capability to serve at a meta-level in providing the semantics of programming languages, specification and modelling languages as well as higher- level and domain-specific formal notations; and, finally, how some of these higher-level and domain-specific notations may be lifted at an interdisciplinary level. Within this historical review, we are inspired by Luis Barbosa's ``components as coalgebras{''} approach in seeing that the duality data-process is underlying all those aspects of formal methods. We also see that such a duality may not only be expressed in universal terms within category theory, but may also be characterised in practical terms and focused applications by two distinct logic paradigms, equational logic for the data and rewriting logic for the process, by two modelling directions, forward process definitions and backward data-driven process transformations, and by the distinction between syntax, defined by the data structures, and semantics, provided by rewrite rules. We use the Maude modelling language to illustrate the application of the data- process duality. In fact, Maude use equational logic to define data types and rewriting logic to express system evolution. Illustrative examples are from the areas of cognitive science and human- computer interaction (HCI). We then define a data-driven model transformation, which we call elaborative mining, , which adopts a backward perspective to recover a behaviour that was observed in real life but was not predicted forward by the original model. Finally, we see how the ``open source software bazaar{''}, which is a metaphor for the apparently chaotic open source development process, offers us a big data context to lift the driving process for model transformation from deterministic to statistical.",10.1016/j.jlamp.2024.101006
+1266,Article,Open or closing doors? The influence of `digital sovereignty' in the EU's Cybersecurity Strategy on cybersecurity of open-source software,"`Digital sovereignty' is the geopolitical mantra of the moment. A key agent of that policy shift, the European Union ('EU') has increasingly embraced `digital sovereignty' as both the ideological foundation and impetus for building its digital future in accordance with `European values and principles,' often driven by and intersecting with cybersecurity concerns as articulated in its 2020 Cybersecurity Strategy for the Digital Decade ('Strategy'). Yet it is impossible to consider cybersecurity without open-source software ('OSS'). Increasingly, the EU, USA and other Governments have recognised that fact in the wake of HeartBleed and Log4j incidents. OSS' decentralised governance and ubiquity, underpinning most software worldwide, may amplify vulnerabilities and adverse effects of cyberattacks, whilst its typically collaborative model of development and innovation often fosters valuable, open cybersecurity solutions. In navigating that policy tightrope of OSS as a double-edged sword for cybersecurity, the EU has adopted `closed' language of `digital sovereignty' that is ostensibly contrary to the `open' nature of OSS. That rhetorical duality is particularly pronounced since the EU described OSS as a tool for realising its `digital sovereignty,' in addition to policy support for `a global, open, interoperable cyberspace' alongside the pursuit of `digital sovereignty.' While there is a epistemic gap in understanding the relationship between the EU's rhetoric of `digital sovereignty' and reality, nascent studies indicate that it has a tangible effect on policy change in multiple digital spheres, generally furthering a degree of `control.' However, that relationship within the OSS cybersecurity context has underexplored and poorly understood, although that policy is a priority for the EU and may bear significant implications for OSS globally. Particularly analyzing the Cyber Resilience Act ('CRA') as key means for implementing the EU's Strategy and its first cybersecurity legislation that would comprehensively engage OSS if adopted by the Council, this article argues that the EU's desire to strengthening cybersecurity in OSS is generally welcome. Yet there is an ostensibly a disjunct between `digital sovereignty' that underpins that legislation and OSS cybersecurity, with too much control of OSS potentially proving counterproductive for EU cybersecurity. This paper illustrates that (i) it is imperative for the EU to address OSS cybersecurity; (ii) yet the lens of digital sovereignty is ostensibly a rough fit for that approach, considering OSS' philosophy and practice; and (iii) based on the CRA, EU's practice of translating `digital sovereignty' into policy change is mixed, leaving uncertain ramifications for OSS cybersecurity in the EU and beyond. On the one hand, it moves towards more `control' at least in determining definitional parameters and power dynamics with novel `stewardship' positions for certain OSS entities. That said, the EU generally seeks to leverage OSS to further their regional embrace of OSS rather than to exclude others. Ultimately, the EU has a valuable leadership opportunity to drive forward solutions to OSS cybersecurity in collaboration with others whilst avoiding fragmentation, keeping doors open in recognising that global challenges demand global solutions. That is in its enlightened self-interest.",10.1016/j.clsr.2024.106078
+1267,Article,Optimization based on expanded maintenance model considering OSS edge computing,"We have proposed the maintenance effort assessment model based on two Wiener processes for the operation of open source software (OSS) used in the edge computing in the past. In particular, we consider that this proposed model can assess the reliability by using three dimensional graph. Then, we have proposed two-dimensional modeling based on the effort management in the past. In this paper, we propose new expanded maintenance model considering OSS edge computing by expanding the existing two Wiener processes model in order to consider the network environment under the edge OSS operation. Especially, it is important to control the amount of maintenance effort expense in the long-term phase. Then, we propose the optimization method based on the past two-dimensional Wiener processes model.

+1269,Article,Optimizing fully-efficient two-stage models for genomic selection using open-source software,"Genomic-assisted breeding has transitioned from theoretical concepts to practical applications in breeding. Genomic selection (GS) predicts genomic breeding values (GEBV) using dense genetic markers. Single-stage models predict GEBVs from phenotypic observations in one step, fully accounting for the entire variance-covariance structure among genotypes, but face computational challenges. Two-stage models, preferred for their simplicity and efficiency, first calculate adjusted genotypic means accounting for spatial variation within each environment, then use these means to predict GEBVs. However, unweighted (UNW) two-stage models assume independent errors among adjusted means, neglecting correlations among estimation errors. Here, we show that fully-efficient two-stage models perform similarly to UNW models for randomized complete block designs but substantially better for augmented designs. Our simulation studies demonstrate the impact of the fully-efficient methodology on prediction accuracy across different implementations and scenarios. Incorporating non-additive effects and augmented designs significantly improved accuracy, emphasizing the synergy between design and model strategy. Consistent performance requires the estimation error covariance to be incorporated into a random effect (Full\\_R model) rather than into the residuals. Our results suggest that the fully-efficient methodology, particularly the Full\\_R model, should be more prevalent, especially as GS increases the appeal of sparse designs. We also provide a comprehensive theoretical background and open-source R code, enhancing understanding and facilitating broader adoption of fully-efficient two-stage models in GS. Here, we offer insights into the practical applications of fully-efficient models and their potential to increase genetic gain, demonstrating a 13.80\\%\\textbackslash{}documentclass{[}12pt]\\{minimal\\} \\textbackslash{}usepackage\\{amsmath\\} \\textbackslash{}usepackage\\{wasysym\\} \\textbackslash{}usepackage\\{amsfonts\\} \\textbackslash{}usepackage\\{amssymb\\} \\textbackslash{}usepackage\\{amsbsy\\} \\textbackslash{}usepackage\\{mathrsfs\\} \\textbackslash{}usepackage\\{upgreek\\} \\textbackslash{}setlength\\{\\textbackslash{}oddsidemargin\\}\\{-69pt\\} \\textbackslash{}begin\\{document\\}\\$\\$13.80\\textbackslash{}\\%\\$\\$\\textbac kslash{}end\\{document\\} improvement after five selection cycles when moving from UNW to Full\\_R models.",10.1186/s13007-024-01318-9

In this context, extensive bug reports and feature requests are raised as issues that need to be resolved. This makes issue resolution prediction become more and more important in project management. To address this problem, this paper constructed a multiple feature set from the perspectives of project, issue, and developer, by combining static and dynamic features of issues. Then, we refine a feature set based on the feature's importance. Furthermore, we proposed a method to explore what features and how these features affect the prediction of issue resolution time.

+1271,Article,Quality enhancement in OSS development process: a quantitative framework approach,"Evaluating the quality of Open Source Software (OSS) on the basis of quantitative success indicators is critically important for project maintainers to assess their performance as well as for businesses and individuals to verify that the software meets their unique requirements. Owing to the unrestricted access to source code, version control information, and bug tracking database, a comprehensive study on the Development Process associated with an OSS project is feasible. In the present research study, a comparison framework has been developed to quantitatively assess and compare the quality of the Development Process of a multitude of OSS projects on the basis of various project dimensions. Five multi-criteria decision analysis techniques have been employed to apply the framework on ten OSS projects and the results are compared with an existing quality assessment model. The findings of the comparative analysis reveal that along with conforming to the results produced by the existing assessment model, the proposed framework provides an opportunity for a detailed analysis of the OSS projects, benefiting potential adopters in aligning their needs to the projects and aiding maintainers in strategic resource allocation to weaker areas of the project.",10.1007/s11219-024-09705-0
+1273,Article,Second version of the open-source software GSA for gamma-ray spectrum analysis,"The collaboration among the PRESN team, LaMCScI laboratory and CNESTEN center made it possible to implement the first version of the GSA software. Its first version is already available to the public; it is not only free but also an open source, demonstrating the developers' commitment to promoting the open sharing of scientific knowledge. This first version is characterized by its flexibility and non-commerciality, and it is available without any conditions on the following website: https://www.github.com/LAHCEN-EL-AMRI/Gamma-Spectra-Analysis, allowing users to add personal options, making it a particularly adaptable tool to the different requirements of scientific research. This article deals with the second version of GSA, which focuses on a core and complementary feature: the calculation of isotope activity. In order to accomplish this goal, instead of implementing a single efficiency formula, as is often the case in most software, four formulas were integrated. The users can therefore select the one they want to implement. To ensure the accuracy and reliability of this new feature, a validation was performed on GSA. The results obtained with GSA v2 were carefully studied by comparing them to those obtained with the renowned Genie 2000 software. Owing to this comparison step, it was possible to verify and confirm the accuracy of the results of GSA version 2. This second version of GSA is available as a free and open source software on the following site: https://www.github.com/LAHCEN-EL-AMRI/GSA-v2/tree/master.",10.1039/d4ja00398e
+1274,Article,Systematic Literature Review of Commercial Participation in Open Source Software,"Open source software (OSS) has been playing a fundamental role in not only information technology but also our social lives. Attracted by various advantages of OSS, increasing commercial companies are participating extensively in open source development, and this has had a broad impact. Enormous research efforts have been devoted to understanding this phenomenon and trying to pursue a win-win result. To characterize the current research achievement and identify challenges, this article provides a comprehensive systematic literature review (SLR) of existing research on company participation in OSS. We collected 105 papers and organized them based on their research topics, which cover three main directions, i.e., participation motivation, contribution model, and impact on OSS development. We found that companies have diverse motivations from economic, technological, and social aspects, and no one study covered all the motivation categories. Existing studies categorize five main companies’ contribution models in OSS projects through their objectives and how they shape OSS communities. Researchers also explored how commercial participation affects OSS development, including companies, developers, and OSS projects. This study contributes to a comprehensive understanding of commercial participation in OSS development. Based on our findings, we present a set of research challenges and promising directions for companies’ better participation in OSS.",10.1145/3690632

+1278,Article,Understanding the OSS Communities of Deep Learning Frameworks: A Comparative Case Study of PYTORCH and TENSORFLOW,"Over the past two decades, deep learning has received tremendous success in developing software systems across various domains. Deep learning frameworks have been proposed to facilitate the development of such software systems, among which, PYTORCH and TENSORFLOW stand out as notable examples. Considerable attention focuses on exploring software engineering practices and addressing diverse technical aspects in developing and deploying deep learning frameworks and software systems. Despite these efforts, little is known about the open source software communities involved in the development of deep learning frameworks. In this article, we perform a comparative investigation into the open source software communities of the two representative deep learning frameworks, PYTORCH and TENSORFLOW. To facilitate the investigation, we compile a dataset of 2,792 and 3,288 code commit authors, along with 9,826 and 19,750 participants engaged in issue events on GITHUB, from the two communities, respectively. With the dataset, we first characterize the structures of the two communities by employing four operationalizations to classify contributors into various roles and inspect the contributions made by common contributors across the two communities. We then conduct a longitudinal analysis to characterize the evolution of the two communities across various releases, in terms of the numbers of contributors with various roles and role transitions among contributors. Finally, we explore the causal effects between community characteristics and the popularity of the two frameworks. We find that the TENSORFLOW community harbors a larger base of contributors, encompassing a higher proportion of core developers and a more extensive cohort of active users compared to the PYTORCH community. In terms of the technical background of the developers, 64.4\\% and 56.1\\% developers in the PYTORCH and TENSORFLOW communities are employed by the leading companies of the corresponding open source software projects, Meta and Google, respectively; 25.9\\% and 21.9\\% core developers in the PYTORCH and TENSORFLOW communities possess Ph.D. degrees, while 77.2\\% and 77.7\\% contribute to other machine learning or deep learning open source projects, respectively. Developers contributing to both communities demonstrate spatial and temporal similarities to some extent in their pull requests across the respective projects. The evolution of contributors with various roles exhibits a consistent upward trend over time in the PYTORCH community. Conversely, a noticeable turning point in the growth of contributors characterizes the evolution of the TENSORFLOW community. Both communities show a statistically significant decreasing trend in the inflow rates of core developers. Furthermore, we observe statistically significant causal effects between the expansion of communities and retention of core developers and the popularity of deep learning frameworks. Based on our findings, we discuss implications, provide recommendations for sustaining open source software communities of deep learning frameworks, and outline directions for future research.",10.1145/3705303
