The Internet has enabled online social interaction for scientists that previously happened only in physical meetings and conferences. Yet despite these innovations in communication, dissemination of methods is often relegated to the slow process of academic publishing. Further, these methods remain static, with subsequent advances published elsewhere and unlinked. For communities undergoing fas...

Virtual worlds (VWs) are computer-simulated environments which allow users to create their own virtual character as an avatar. With the rapidly growing user volume in VWs, platform providers launch virtual goods in haste and stampede users to increase sales revenue. However, the rapidity of development incurs virtual unrelated items which will be difficult to remarket. It not only wastes virtua...

Organizations have started to realize the economic value of virtual communities. Unfortunately, traditional management methods of control do not work on virtual communities. Often, group norms are the principal method of virtual community governance. However, it is not clear how group norms are formed in virtual communities, and how managers can shape norm evolution. This research in progress p...

There is debate as to whether chest compression-only cardiopulmonary resuscitation (CC-CPR) or standard 30:2 CPR should be taught to laypersons. Equivalence in outcomes between standard CPR and CC-CPR has been amply demonstrated in communities with short ambulance response times of about five minutes. Depriving oxygen from a collapsed patient beyond six minutes results in poorer outcomes. Commu...

Individuals are increasingly turning to computermediated communication in order to get information on which to base their decisions. For instance, many consumers are using newsgroups, chat rooms, forums, e-mail list servers, and other online formats to share ideas, build communities and contact other consumers who are seen as more objective information sources (Kozinets, 2002). These social gro...

Understanding requirements of mobile communities is challenging because of their geographical distribution and frequent movement. We present a study of backpackers travelling in Australia which utilizes a research method called contextual postcard questionnaires. The method uses brief, openended questions to solicit contextual responses from backpackers that are relevant for development of tour...

This paper deals with the concept of informal learning in virtual communities on the Internet. Initially we discuss the need for continuing education and its relation with informal learning. Virtual communities are next defined and then compared to real communities. Case studies are employed, focused on some specific kinds of virtual communities. We examine how they operate, how their members i...
