This research examines communities of practice and open source software tools in development of scalable virtual infrastructures for the regional Virtual Health Library of the Latin American and Caribbean Health Sciences System (Bireme) and embedded national cases. Virtual infrastructures refer to an environment characterized by overlapping distribution networks accessible through Internet portals and websites designed to facilitate integrated use of available resources. Case analysis shows engagement of interdisciplinary communities of practice for scalable virtual infrastructure design. This research program considers theory and methods for study of transferability of the Latin American model to large health care systems in other cultures.}, keywords = {Bireme, Communities Of Practice, culture, open source systems, virtual infrastructures}, author = {Seror, Ann} } @article {Fang:2009:USP:1554441.1554443, title = {Understanding Sustained Participation in Open Source Software Projects}, journal = {J.

Sharpe, Inc.}, address = {Armonk, NY, USA}, abstract = {Prior research into open source software (OSS) developer participation has emphasized individuals{\textquoteright} motivations for joining these volunteer communities, but it has failed to explain why people stay or leave in the long run. Building upon Lave and Wenger{\textquoteright}s theory of legitimate peripheral participation (LPP), this paper offers a longitudinal investigation of one OSS community in which sustained participation is hypothesized to be associated with the coevolution of two major elements of LPP theory: "situated learning" (the process of acting knowledgeably and purposefully in the world) and "identity construction" (the process of being identified within the community). To test this hypothesis, data were collected from multiple sources, including online public project documents, electronic mail messages, tracker messages, and log files. Results from qualitative analyses revealed that initial conditions to participate did not effectively predict long-term participation, but that situated learning and identity construction behaviors were positively linked to sustained participation. Furthermore, this study reveals that sustained participants distinguished themselves by consistently engaging in situated learning that both made conceptual (advising others) and practical contributions (improving the code). Implications and future research are discussed.}, keywords = {Communities Of Practice, Legitimate Peripheral Participation, Open Source Projects, Open Source Software Community, Qualitative Study}, issn = {0742-1222}, doi = {10.2753/MIS0742-1222250401}, url = {http://portal.acm.org/citation.cfm?id=1554441.1554443}, author = {Fang, Yulin and Neufeld, Derrick} } @conference {Krogstie:2008:PTB:1368088.1368201, title = {Power through brokering: open source community participation in software engineering student projects}, booktitle = {Proceedings of the 30th international conference on Software engineering}, series = {ICSE {\textquoteright}08}, year = {2008}, pages = {791{\textendash}800}, publisher = {ACM}, organization = {ACM}, address = {New York, NY, USA}, abstract = {Many software engineering projects use open source software tools or components. The project team{\textquoteright}s active participation in the open source community may be necessary for the team to use the technology. Based on an in-depth field study of industry software engineering project students interacting with an open source community, we find that participation in the community may affect the team{\textquoteright}s work and learning by strengthening the power of the broker between the team and the community. We outline pitfalls and benefits of having student teams acquire development-related knowledge from open source communities. The findings are relevant to the organization and supervision of software engineering student projects interacting with open source communities.}, keywords = {Communities Of Practice, computer science education, FLOSS, open source, software engineering, software engineering education}, isbn = {978-1-60558-079-1}, doi = {10.1145/1368088.1368201}, url = {http://doi.acm.org/10.1145/1368088.1368201}, author = {Krogstie, Birgit R.} }
