Under standard models of expected utility, preferences over stochastic events are assumed to be independent of the source of uncertainty. Thus, in decision-making, an agent should exhibit consistent preferences, regardless of whether the uncertainty derives from the unpredictability of a random process or the unpredictability of a social partner. However, when a social partner is the source of ...

abstract this paper proposes an approach to find an optimum structure for educational levels of human forces. to this end, a linear programming (lp) model integrated with a social accounting matrix (sam) was employed. the integrated model was employed using the sam of golestan province of iran. it was demonstrated that when unemployment is the result of inconsistency between supply and demand f...

Recent studies have begun to elucidate the roles played in social cognition by specific neural structures, genes, and neurotransmitter systems. Cortical regions in the temporal lobe participate in perceiving socially relevant stimuli, whereas the amygdala, right somatosensory cortices, orbitofrontal cortices, and cingulate cortices all participate in linking perception of such stimuli to motiva...

With the rapid growth of the Internet, more and more people interact with their friends in online social networks like Facebook. Currently, the privacy issue of online social networks becomes a hot and dynamic research topic. Though some privacy protecting strategies are implemented, they are not stringent enough. Recently, Semi-Supervised Learning (SSL), which has the advantage of utilizing th...

The ever increasing volume of available social network datasets creates the need to derive anonymization methods that permit useful analysis of such datasets without disclosing any sensitive information regarding their users. In this article, we review the problem of privacy in online social networks focusing on related models and algorithms.

As the popularity of social networks expands, the information users expose to the public has potentially dangerous implications for individual privacy. While social networks allow users to restrict access to their personal data, there is currently no mechanism to enforce privacy concerns over content uploaded by other users. As group photos and stories are shared by friends and family, personal...

A number of web service firms have started to authenticate users via their social knowledge, such as whether they can identify friends from photos. We investigate attacks on such schemes. First, attackers often know a lot about their targets; most people seek to keep sensitive information private from others in their social circle. Against close enemies, social authentication is much less effec...

Mobile social network is essentially relational rather than attribute based on the unit analysis the individual but structures that consist of at least two social entities and the links among them. Search a friend in mobile social network profile matching two users comparing their personal profiles and conflicts with users growing privacy concerns about disclosing the personal profile to comple...
