Our perception of trust works as a compass for safe navigation through a world of uncertainty.

On the other hand it helps us steer away from unacceptable risks and potential deceptions. While human intuition about trust often fails, it seems to provide us with guidance very quickly in m...

Based on the model of emotion as social information, this study explores effects facial emotions and trustworthy behavior trust decision-making in game through two experiments. The present used impact players’ emotion, arousal individual results can be summed up follows: (1) repeated interaction with four players, individuals invest more players than untrustworthy players; (2) invested happy em...

Trust is a major aspect of decision making when two parties are involved, and the lack of face to face exchanges of the Internet deeply changes relations and behaviours regarding the available services.

Trust is a social phenomenon that impacts the situation awareness of individuals and indirectly their decision-making. However, most of the existing computational models of situation awareness do not take interpersonal trust into account. Contrary to those models, this study introduces a computational, agent-based situation awareness model incorporating trust to enable building more human-like ...

A theoretical visual interaction framework to model consensus in social network group decision making (SN-GDM) is put forward with following three main components: (1) construction of trust relationship; (2) trust based recommendation mechanism; and (3) visual adoption mechanism. To do that, dual trust propagation is investigated to connect incomplete trust relationship by trusted third partner...

Grid computing enables the sharing of heterogeneous resources within virtual organizations. Since entities in virtual organizations are independently administrated, cross-domain management of access control and intrusion protection is critical for grid services. To provide better protection in grid systems, multiple domains collaborate in making security decisions. Unfortunately, the absence of...
