Some applicants may hold a post initially. These posts may be assigned to other applicants if their holders get another post. By reducing the problem to a sequence of maximum cardinality bipartite matchi...

Granovetter’s theory on the strength of weak ties provides an analysis of processes in interpersonal networks forming a very fruitful micro-macro bridge in sociology. When applied to organizations, theories of weak ties give a basis for understanding the mechanisms of work interoperability and information exchange.

We explore the effects of individualand network-level negative word-of-mouth on the firm’s profits using an agent-based model and specifically, an extended small world analysis. We include both permanent strong ties within the social network, and changing, often random, weak ties with other networks. The effect of negative word-of-mouth on the Net Present Value (NPV) of the firm was found to be...

Weak ties play a significant role in the structures and the dynamics of community networks. Based on the contact process, we study numerically how weak ties influence the predictability of epidemic dynamics. We first investigate the effects of the degree of bridge nodes on the variabilities of both the arrival time and the prevalence of disease, and find out that the bridge node with a small de...
