An intelligent agent may receive information about its environment from several different sources. How should the agent merge these items of information into a single, consistent piece? Taking our lead from the contraction + expansion approach to belief revision, we envisage a two-stage approach to this problem. The first stage consists of weakening the individual pieces of information into a f...

Building on Posner (Posner, Daniel N. 2005. Institutions and Ethnic Politics in Africa. New York: Cambridge University Press), this article describes a framework for organizing the information about a community’s social cleavage structure so as to identify the incentives that individuals face to adopt particular social identities. The framework is parsimonious but powerful: it generates predict...

This article elaborates on foundational issues in the social sciences and their impact on the contemporary theory of belief revision. Recent work in the foundations of economics has focused on the role external social norms play in choice. Amartya Sen has argued in [Sen93] that the traditional rationalizability approach used in the theory of rational choice has serious problems accommodating th...

Analyzing massive user-generated microblogs is very crucial in many fields, attracting many researchers to study. However, it is very challenging to process such noisy and short microblogs. Most prior works only use texts to identify sentiment polarity and assume that microblogs are independent and identically distributed, which ignore microblogs are networked data. Therefore, their performance...

introduction: diabetes is the most common disease related to metabolism disorders with long term complications. it needs lifelong specific self-care, as it causes a promotion in quality of life and decreases disease costs. the health belief model (hbm) is a psychological model that attempts to explain and predict health behaviors. this is done by focusing on the attitudes and beliefs of individ...

A number of studies in the network science literature have attempted to model the effect of network structure on cognitive state fluctuations in social networks. For the most part, these networks use highly simplified models of both cognitive state and social influence. In order to extend these studies and provide the basis for more complex network science simulations, a model of socially-media...

Intelligent agents have to be able to merge inputs received from different sources in a coherent and rational way. Several proposals have been made for the merging of structures in which it is possible to encode the preferences of sources [5, 4, 12, 16, 17, 1]. Information merging has much in common with the goals of social choice theory: to define operations reflecting the preferences of a soc...

in this study, one basic question will be answered: why were women officially considered being the subject of policy making decisions in reza khan era? the answer should be found in the particular logic of the discourse of that time which was “archeological nationalism”. the discourse is based on racist theory and understands social and cultural issues on the same basis. during the gap emerged ...

We study discrete preference games in heterogeneous social networks. These games model the interplay between a player’s private belief and his/her publicly stated opinion (which could be different from the player’s belief) as a strategic game in which the players’ strategies are the opinions and the cost of an opinion in a state is a convex combination through a parameter α ∈ [0, 1] of two fact...
