Recent studies suggest that allowing individuals to choose their partners can help to maintain cooperation in human social networks; this behaviour can supplement behavioural reciprocity, whereby humans are influenced to cooperate by peer pressure. However, it is unknown how the rate of forming and breaking social ties affects our capacity to cooperate. Here we use a series of online experiment...

Social network users connect and interact with one another to fulfil different kinds of social and information needs. When interaction ceases between two users, we say that their tie becomes dormant. While there are different underlying reasons of dormant ties, it is important to find means to revive such ties so as to maintain vibrancy in the relationships. In this work, we thus focus on desig...

In sustainable development projects, as well as other types of projects, knowledge transfer is important for the organisations managing the project. Nevertheless, knowledge transfer among employees does not happen automatically and it has been found that the lack of social networks and the lack of trust among employees are the major barriers to effective knowledge transfer. Social network analy...

This paper investigates the effect of social ties between acquirers and targets on merger performance. Using data on educational background and past employment, we construct a measure of the extent of cross-firm social connection between directors and senior executives at the acquiring and the target firms. We find that between-firm social ties have a significantly negative effect on the abnorm...

Increasing attention is being given to the issue of desistance or cessation in adult criminal careers. We contribute to this research by considering how informal and formal social controls affect recidivism among 556 sex offenders placed on probation in 1992. We conduct an event history analysis of reoffense, based on the predictions of Sampson and Laub's and Gottfredson and Hirschi's control t...

Or does virtuality increase social capital by expanding the range of individuals’ social networks? To address these questions, first, we identify the properties of virtuality, whose definition still varies in a variety of research s...
