Scientists are frequently faced with the important decision to start or terminate a creative partnership. This process can be influenced by strategic motivations, as early career researchers are pursuers, whereas senior researchers are typically attractors, of new collaborative opportunities. Focusing on the longitudinal aspects of scientific collaboration, we analyzed 473 collaboration profile...

What is trust? Should trust be used as a variable or as a process? Is trust in people similar in nature to trust in institutions? These are three main questions I address in this article. I argue that trust is a complex and multi-dimensional phenomenon, which consists of a mix of trust in strong ties, weak ties, and institutions. I explain the need for a new approach to trust, using the Soviet ...

We use variation in wind speeds at sur…ng locations in Switzerland as plausibly exogenous shifters of users’propensity to post content about their sur…ng activity onto an online social network. We exploit this variation to test whether users’online content generation activity a¤ects their social ties, and whether ties in turn a¤ects content generation. Under weak monotonicity assumptions, we al...

There has been a burgeoning literature about interfirm network and innovative performance. However, in reviewing the extant literature we find different interpretations regarding how firms should be tied to one another in networks. The paper employs case study to explore and explain the relative propositions of interfirm network, different organizational learning and technological innovation. I...

What is the dependent variable in social media use? From a research perspective, this is a pertinent question to help explain and understand the behaviors that underpin the widespread adoption and use of social media throughout society. From a practical perspective, the question is relevant for social media technology providers, for businesses that use social media, and community organizations ...

In this paper we examine the influence of strategic technology alliances on organisational learning. From an empirical perspective we examine the preand post-alliance knowledge bases of allying firms. We find that the pre-alliance knowledge base overlap of the allying firms has an inverted U-shaped relationship with the degree of learning taking place in the alliance. Alliances established for ...

This study examines whether there is an association between network social capital and self-rated health after controlling for social support. Moreover, we distinguish between network social capital that emerges from strong ties and weak ties. We used a cross-sectional representative sample of 815 adults from the Belgian population. Social capital is measured with the position generator and per...

In the two studies reported here, we examined the relation among residential mobility, economic conditions, and optimal social-networking strategy. In study 1, a computer simulation showed that regardless of economic conditions, having a broad social network with weak friendship ties is advantageous when friends are likely to move away. By contrast, having a small social network with deep frien...

Driven by the increasing popularity of crowdfunding, academic researchers have examined the impacts of internal social capital accumulated on crowdfunding platforms and external social capital formed through online and offline friend networks on campaign success. However, no research has examined the impacts of social networks from a structural perspective. In the current research, we investiga...
