Purple: A Modular System for Developing and Deploying Behavioral Intervention Technologies
by Stephen M Schueller, Mark Begale, Frank J Penedo, David C Mohr
(Published on 30 Jul 2014)
The creation, deployment, and evaluation of Web-based and mobile-based applications for health, mental health, and wellness within research settings has tended to be siloed, with each research group developing their own systems and features. This has led to technological features and products that are not sharable across research teams, thereby limiting collaboration, reducing the speed of dissemination, and raising the bar for entry into this area of research. This paper provides an overview of Purple, an extensible, modular, and repurposable system created for the development of Web-based and mobile-based applications for health behavior change. Purple contains features required to construct applications and to manage and evaluate research trials using these applications. Core...
Virtual Communities of Practice: Overcoming Barriers of Time and Technology
by Kieran Walsh, Stephen Barnett
(Published on 29 Jul 2014)
Barnett et al should be congratulated for their fascinating report into the use of virtual communities of practice for family physician training . It is interesting that the respondents reported time as a barrier to their participation in the community of practice. Undoubtedly, it would have taken them time to take part, but the amount of time needed should be placed in context and compared with the time needed to partake in face-to-face communities of practice. Face-to-face participation would take far more time—not least the time required to travel to the venue of the community of practice meeting. So in truth, virtual communities of practice are far more likely to be time saving. However the feeling that time was a barrier cannot be dismissed out of hand. The fact that...
