We study markets with indivisible goods where monetary compensations are not possible. Each individual is endowed with an object and a preference relation over all objects. When preferences are strict, Gale’s top trading cycle algorithm finds the unique core allocation. When preferences are not necessarily strict, we use an exogenous profile of tie-breakers to resolve any ties in individuals’ p...

How do new scientific ideas diffuse? Computational studies reveal how network structures facilitate or obstruct diffusion; qualitative demonstrate that diffusion entails the continuous translation and transformation of ideas. This article bridges these computational approaches to study as a complex process adaptation. As case study, we analyze spread Granovetter's Strength Weak Ties hypothesis,...

The effect of weather on social interaction has been explored through the analysis of a large mobile phone use dataset. Time spent on phone calls, numbers of connected social ties, and tie strength were used as proxies for social interaction; while weather conditions were characterized in terms of temperature, relative humidity, air pressure, and wind speed. Our results are based on the analysi...

U the determinants of creativity at the individual and organizational level has been the focus of a long history of research in various disciplines from the social sciences, but little attention has been devoted to studying creativity at the dyadic level. Why are some dyadic interactions more likely than others to trigger the generation of novel and useful ideas in organizations? As dyads condu...

Network topology and its relationship to tie strengths may hinder or enhance the spreading of information in social networks. We study the correlations between tie strengths and topology in networks of scientific collaboration, and show that these are very different from ordinary social networks. For the latter, it has earlier been shown that strong ties are associated with dense network neighb...

Linear discrepancy and weak discrepancy have been studied as a measure of fairness in giving integer ranks to points of a poset. In linear discrepancy, the points are totally ordered, while in weak discrepancy, ties in rank are permitted. In this paper we study the t-discrepancy of a poset, a hybrid between linear and weak discrepancy, in which at most t points can receive the same rank. Intere...

Ties and social bonds are considered as social capital and assets of the person and the person can be accessed at these links from the resources and support has great importance in sociology. The overall goal of this research was to study social networks and social ties of women and their husbands, living in Babol. Types of social networks(formal relationships, informal relationships) and the s...
