In the first phase of game, the bounded rationality group players adopt the replicator dynamic behavior. Secondly, the full rationality individual player decides the own response function by the strategies distribution of group players. The shortsighted individual player will take the risk-dominant strategy. This model has some unique characteristics.展开更多

The reliability and accuracy of interpersonal perception in the virtual environment is an intriguing issue. Using the Social relations model (SRM) [1], this paper investigates interpersonal perception in virtual groups from a multilevel perspective. In particular, it examines the following three areas: homophily, identification, and individual attraction, and explores how much of these directional and dyadic relational evaluations can be attributed to the effect of the actor, the partner, and the relationship.展开更多
针对隧道工程施工安全问题,从隧道工人行为角度出发,结合问卷调查数据,建立分层线性模型(hierarchical linear model,HLM),从微观上解释了安全行为关联因素影响过程。利用信效度评价检验了309份有效数据的可靠性,通过假设检验依次分析...针对隧道工程施工安全问题,从隧道工人行为角度出发,结合问卷调查数据,建立分层线性模型(hierarchical linear model,HLM),从微观上解释了安全行为关联因素影响过程。利用信效度评价检验了309份有效数据的可靠性,通过假设检验依次分析了隧道工人群体安全行为对个体安全行为、安全氛围以及团队效能的影响作用。结果表明,群体安全行为对个体安全行为具有显著正向影响;安全氛围在群体安全行为与个体安全行为之间具有中介作用;团队效能在安全氛围与个体安全行为之间具有正向调节作用。以上结果为更好地发挥安全行为在隧道施工安全管理中的作用提供了指导。展开更多

This paper focuses on the social mechanisms of rumor fulfilling. Rumors with important contents related to people’s personal interests win acceptance through changing people’s expected payoffs, misleading people to the belief that acceptance of the rumor would beneficially outperform rejection of it. Nevertheless, it is risky to believe rumors; therefore, people make their decision whether to believe a rumor or not by referring to other people’s choices. An analysis was performed first within a game model that incorporated the variables of an individual’s expectancy and other people’s impact to predict whether the individual would accept or reject a rumor. Another analysis followed to further examine the functions of some dynamic mechanisms in rumor fulfilling when group pressure and network effects were introduced. Finally, an exploratory discussion on how to prevent rumors and erase their effects via information management strategies was presented.展开更多
