This study draws on absorptive capacity theory and organizational learning perspective to examine and elaborate the roles of IT in influencing firm innovation in the alliance network context of pharmaceutical industry. We focused on three types of IT-enabled knowledge capabilities and one specific type of alliance network structure structural holes and examine whether and how they interact to j...

Innovation has been a topic of considerable interest to researchers and practitioners. Particularly, the networks within which firms operate and their properties (e.g., structural holes) are suggested to affect firms’ innovation performance. One stream of research finds that structural holes are conducive to firms’ innovation because of the heterogeneous information about alternatives that firm...

We develop a contingency theory for how structural closure in a network, defined as the extent to which an actor’s network contacts are connected to one another, affects the initiation and adoption of change in organizations. Using longitudinal survey data supplemented with eight indepth case studies, we analyze 68 organizational change initiatives undertaken in the United Kingdom’s National He...

An increasing number of students, professionals, and job-recruiters are using Social Network Sites (SNSs) for sharing information. There has been limited research assessing the role of individuals seeking a job and receiving information about job openings in SNSs. In this regard, do students, non-managers, and managers benefit from job offers when they are a member of SNSs such as Facebook or L...

In this paper, the author extends and further develops research and theory on the relationship between cultural taste and social networks by examining the effects of strength of preference in different cultural domains on the relative closure of personal networks. The results show that as the number of strong preferences held by an individual increases, so do the chances that any two of his or ...

However, little has been done to disentangle onemechanism fromanother. This paper empirically tests amediatedmoderationmodel that distinguishes between the five differen...

Through the examination of 11 intact interuniversity research project teams, this study examines the relationship between team leaders, team members, their communication networks (represented as structural holes), and performance. The study shows that in the conduct of their work, the team leaders bridged more structural holes than team members. Although team leaders demonstrated a higher level...

We introduce the concept of the network architect to extend theory explaining how brokers create and manage structural holes in mediated markets. We argue that a broker’s social resources and dependence on the market, along with exogenous deal conditions, influence the broker’s motivations and willingness to make tradeoffs between long-term and short-term considerations when constructing deal n...
