Knowledge contribution in virtual communities is an important issue in the field of knowledge management. Based on Ames's theoretical framework on motivation, we propose a model for knowledge contribution in problem-solving virtual communities (PSVCs). The model includes two second-order individual motivations, with four major mechanisms in PSVCs that are associated with these motivations. Results confirm that only egoistic motives affect members' knowledge contribution in PSVCs. Further, knowledge repository and social identity are found to be important mechanisms for promoting knowledge contribution through egoistic motives. This paper concludes with theoretical and practical implications and provides insights for future research. [ABSTRACT FROM PUBLISHER]
In this paper; we explore the emergence of subgroups in global virtual teams and consider the impact that subgroups have on the communication patterns and interactions of these teams. The study presented here takes the case of eight virtual teams that were formed between two universities in two different countries. Our findings reveal that subgroups exert different degrees of impact on the team as a whole. Where the impact was high. boundaries were created between team members in different subgroups while the development of team cohesiveness was restricted. Nevertheless, all teams were able to produce high quality outcomes, suggesting that the emergence of subgroups may not always have a negative influence on team performance. We discuss the implications of these findings for research and practice. [ABSTRACT FROM AUTHOR]
