SummaryWe examined relationships in a model of organizational cognitive complexity (CC) via a ®eld study. Results, based on a sample drawn from six organizations, indicate that problem familiarity r 0X25, p`0X10 and variety of work experience r 0X29, p`0X05 are related to the number of script tracks available for problem solving. In turn, script tracks are related to CC r À0X26, p`0X10. The relationship between CC and job level is statistically, signi®cantly moderated by job complexity. Finally, chisquare analysis indicates that the data ®t the model as proposed. The organizational implications of CC are discussed and suggestions for future research on the model are made. #

Increasingly, managers of global teams are faced with the challenge of how to foster knowledge sharing within a virtual or hybrid community. In this study, we replicate Chiu, Hsu, and Wang's (2006) study of the influence of social capital factors on knowledge sharing in virtual communities and extend it to reveal how both the quantity and quality of knowledge sharing may mediate between social capital factors and network involvement and commitment. The context of our investigation is a professional hybrid community in Central Eurasia. Using singleindicator structural equation modeling (SEM) to test our proposed model, we were able to demonstrate both convergent and discriminant validity among the study variables. Our study also provides partial support for the proposed model. Implications for research and practice are discussed.
