Individuals are typically members of a variety of web-based social networks (both explicit and implied), but existing trust inference mechanisms typically draw only on a single network in order to calculate trust between any two individuals. This both reduces the likelihood that a trust value can be calculated (as both people have to be members of the same network), and reduces the quality of a...

This study explores the determinants (demographic, personal, behavioural, and social) by which happy and unhappy people differ. The primary sample from which the participants were chosen was a representative sample of Croatian citizens (N = 4000). On the basis of the distribution of overall happiness the sample of the highest (the happy group) and the lowest 10 % of participants (the unhappy gr...

Computing trust between individuals in social networks is important for many intelligent systems that take advantage of reasoning in social situations. There have been many algorithms developed for inferring trust relationships in a variety of ways. These algorithms all work on a snapshot of the network; that is, they do not take into account changes in trust values over time. However, trust be...

Nowadays the effective use of organizational knowledge and sharing it among the staff has become an strategic resource to achieve and maintain competitive advantage. For achieving such Organizations need to have strategies to improve knowledge sharing.

This paper explores the relationship between group membership and trust. Specifically, we examine (1) the importance of trust in the decision to join groups, (2) the subsequent ability of groups to generate trust, and (3) the influence of group membership and trust on a measure of well-being, per capita household income. We use longitudinal data from KwaZulu-Natal Province, South Africa, allowi...

Could the next generation of online communications strengthen civil society by better connecting people to others with whom they share affinities, so they can more effectively exchange information and self-organize? Could such a system help to revitalize democracy in the 21st century? When networked personal computing was first developed, engineers concentrated on extending creativity among ind...

Norms of reciprocity help enforce cooperative agreements in bilateral sequential exchange. We examine the norms that apply in a reciprocal-exchange economy. In our one-shot investment game in a Nairobi slum, people adhered to the norm of “balanced reciprocity,” which obligates quid-pro-quo returns for any level of trust. The norm is gendered, with people more likely to comply when confronted wi...

Social networks based trust is a promising approach to supporting people and software agents to interact with “strangers” on the Web. A necessary condition for trust propagation in social networks is that trust is transitive. However, is trust transitive? What types of trust are transitive and why? There are few theories and models found to answer these fundamental questions in a formal manner....
