摘要：We tested several hypotheses derived from an extended version of Shamir, House, and Arthur's (1993) theory of charismatic leadership. We used three different samples of subordinates to assess leader behavior, individual-level correlates, and unit-level correlates, respectively. We also examined the effects of charismatic behaviors and unit-level correlates on superiors' assessments of leaders' performance. The findings provide only Very partial support for the theory and indicate a need for gr...

摘要：This study explored the use of clique analysis for explaining network effectiveness. In data from networks of mental health agencies in three cities, effectiveness, measured as client outcomes, was negatively related to the integration of full networks. In contrast, effectiveness was positively related to integration among small cliques of agencies when these cliques bad overlapping links through both reciprocated referrals and case coordination. The findings have implications for both theory ...

We also investigated the relationship between out comes and the relative frequency of reciprocated contentious communications. Results confirmed the hypotheses, showing that extreme distributive outcomes are related to the relative frequency of reciprocated contentious communications and that conflict spirals can be stopped by various communication strategies. Theoretical and pr...

摘要：Using distinctiveness theory, this research showed that the relative rarity of a group in a social context tended to promote members' use of that group as a basis for shared identity and social interaction. Relative to majority group members, racial minorities and women in a master of business administration cohort were more likely to make identity and friendship choices within-group. The marginalization of racial minorities in the friendship network resulted both from exclusionary pressures a...

Human capital was captured by firm-level proxies for firm tenure, industry experience, and graduate education. The social capital proxy was professionals' ties to potential clients.. Human and social capital strongly predicted firm dissolution, and effects depended an their specificity (uniqueness) and nonappropriability (the ownership ...
