摘要：We propose that performing an independent task alongside a coactor who is an outstanding performer will improve a focal actor's performance. In three studies that ranged from laboratory participants solving anagrams and playing video games to professional golfers competing in the Masters Tournament, performance improved more in the presence of a high-performing coactor than in the presence of a weak-performing coactor. However, when people were asked to compete directly with a strong performer...

摘要：Which comes first-team social networks or emergent team states (e.g., team climate)? We argue that team members' social network ties and team members' climate perceptions coevolve over time as a function of six reciprocal and co-occurring processes. We test our conceptual framework in a 10-month longitudinal study of perceptions of team psychological safety and social network ties in 69 work teams and find considerable support for our hypotheses. Our main results suggest that perceptions of ps...

摘要：This study attempts to reconcile previous findings that show both positive and negative outcomes associated with blended workgroups (i.e., workgroups consisting of both temporary and standard workers). Specifically, we conceptualize temporary and standard work as part of a naturally occurring status hierarchy in organizations and propose that blended workgroups have opposing effects on employees depending on employees' perceptions of their potential for upward mobility in that organization. We...

摘要：This paper builds on Granovetter's distinction between strong and weak ties [Granovetter, M. S. 1973. The strength of weak ties. Amer J. Sociol. 78(6) 1360-1380] in order to respond to recent calls for a more dynamic and processual understanding of networks. The concepts of potential and latent tie are deductively identified, and their implications for understanding how and why networks emerge, evolve, and change are explored. A longitudinal empirical study conducted with companies operating i...

摘要：An extensive body of knowledge exists on network outcomes and on how network structures may contribute to the creation of outcomes at different levels of analysis, but less attention has been paid to understanding how and why organizational networks emerge, evolve, and change. Improved understanding of network dynamics is important for several reasons, perhaps the most critical being that the understanding of network outcomes is only partial without an appreciation of the genesis of the networ...

摘要：We introduce status conflicts-defined as disputes over people's relative status (i.e., respect) positions in their group's social hierarchy-as a key group process that affects task group performance. Using mixed research methods, we qualitatively identify the characteristics of status conflicts, validate a four-item survey scale that distinctly measures status conflict, and investigate the relationship between status conflict and group performance. We determine that status conflict exerts a si...

摘要：This article introduces a model of the development of instrumental networks inside organizational groups. We provide a theoretical framework and empirically test a series of hypotheses pertaining to the relationships between socialized charismatic leadership (SCL) and its consequences in terms of cooperative and sanctioning group behavior. We then examine whether these behaviors predict the density of instrumental networks inside groups and, consequently, their performance. Our findings, based...

摘要：In this paper we focus on the temporal and historical conditions under which bridging ties from the past affect current organizational outcomes. Whereas previous research has shown that bridging ties have high decay rates and short-term effects, we explore the possibility that bridging ties may produce benefits over an extended period of time. In particular, we contrast the conventional view of bridging ties having rapidly decaying effects with two alternative network dynamics suggesting accum...

摘要：This paper develops a concept of a multiplex triad, i.e., a triplet composed of actors playing different roles and interconnected by different kinds of relationships. An example of such triad is a social structure comprising two producers connected via horizontal relationships and a customer connected to producers via vertical ties. Multiplex triads are important drivers of network evolution, but their dynamics remains poorly understood. Although conventional wisdom suggests that horizontal ti...

摘要：Organizations mediate societal cultural belief systems and group-level encounters by filtering, and sometimes transforming, social information regarding which status characteristics are salient during group encounters embedded within organizations. This study uses status characteristics theory to add to our understanding of social status within organizations by explaining why organizations matter in determining which status characteristics will be activated within task groups. By analyzing sta...
