In this paper, we empirically analyze the effects of social relations on the recommendation of mobile applications in a community of students at a university. We identify three social relations by questionnaires and two relations by students properties, and examine their effects from a wide variety of perspectives in the framework of top-N recommendation by user and item based collaborative fil...

The literature’s analysis has identified three social mechanisms explaining the similarity between people connected in the network of social relations: homophily, confounding and social contagion. The article proposes a model for simulating mechanisms responsible for similarity of attitudes in networks of social relations; along with a measure that is able to indicate which of the three mechani...

Extensive research has investigated societal and behavioral consequences of social group affiliation and identification but has been relatively silent on the role of perception in intergroup relations. We propose the perceptual model of intergroup relations to conceptualize how intergroup relations are grounded in perception. We review the growing literature on how intergroup dynamics shape per...

Certain statistical aspects of social systems are described by appropriately defined quantities named social potentials. Relations between social potentials are postulated by drawing an analogy with thermodynamics relations between thermodynamic potentials, thus obtaining a toy model of some of the statistical properties of social systems. Within this model, an interpretation of a socially rele...

Duffield et al. (2008: 291) identify that ‘Alliances are one of the most significant phenomena in security studies and world politics more generally’, while Modelski (1963: 773) considers them ‘one of a dozen ...
