Hollenberg, Quantum Inf. Comput. 7 （2007） 111] in the presence of decoherence using different quantum channels such as amplitude damping, depolarizing and phase damping. It is seen that the outcomes of the games for the two damping channels with maximum values of decoherence reduce to same value. However, in comparison to phase damping channel, the payoffs of cooperators are strongly damped under the influence amplitude damping channel for the lower values of decoherence parameter. In the case of depolarizing channel, the game is a no-payoff game irrespective of the degree of entanglement in the initial state for the larger values of decoherence parameter. The deeoherenee gets the cooperators worse off.展开更多

This research, using both quantitative and qualitative data, focused on whether users of the most popular MMOG, World of Warcraft （WOW）, exhibited behaviors of social capital in their online gaming activity and whether there was any correlation to offiine social capital. The findings indicated that cooperation provided the best indicator to make a correlation about a gamer＇s offiine social capital behaviors. One conclusion, stemming from this is that, in virtual worlds, the added social capital can lead to cronyism and help those in power maintain the status quo.展开更多
