Organizations often rely on social networks in order to garner resources for survival, in particular when faced with a crisis. From a resource dependence perspective, this paper addresses two issues regarding the dynamics of inter-organizational ties during crisis situations: (a) what is the usual process organizations use, and (b) how efficient is such a process? Two real world crisis cases sh...

This article contributes to the literature on network strategies and institutional transitions in emerging economies in Asia by identifying a realistic, intermediate phase between the early and late phases of institutional transitions suggested by Peng (2003). Focusing on the intermediate phase, we advance two arguments based on network strength and network content. First, in terms of network s...

Social disorganization theory posits that individuals who live in disadvantaged neighborhoods are more likely to engage in antisocial behavior than are those who live in advantaged neighborhoods and that neighborhood disadvantage asserts this effect through its disruptive impact on social ties. Past research on this framework has been limited in two respects. First, most studies have concentrat...

The problem of aggregating multiple rankings into one consensus ranking is an active research topic especially in the database community. Various studies have implemented methods for rank aggregation and may have come up with contradicting conclusions upon which algorithms work best. Comparing such results is cumbersome, as the original studies mixed different approaches and used very different...

Most of the computational study of election problems has assumed that each voter’s preferences are, or should be extended to, a total order. However in practice voters may have preferences with ties. We study the complexity of manipulative actions on elections where voters can have ties, extending the definitions of the election systems (when necessary) to handle voters with ties. We show that ...

Goldenberg, Libai & Muller (2001) achieved two outcomes: empirical support for a fundamental theory of communications, known as the “strength of weak ties” (Granovetter 1973), and an explication of small-worlds simulations in marketing. Where Goldenberg et al found that weak-ties had as much or more effect on information dissemination than did strong ties, a near-exact replication, reported in ...

Against the background of the changing relationships between trade unions and political parties in Western Europe, this paper examines the nature and outcomes of union–party alliances in East Central Europe. The paper advances two interrelated arguments. First, the nature of union–party ties in postcommunism is significantly different and can be best described as an inverse dependency relations...
