The traditional approach to the ecological problem,which heavily relies on the government or the market,fails to fundamentally address the problem. Instead,as the social capital in the countryside,the relationship network,norms and trust can effectively resolve rural ecological environmental crisis by highlighting the method of"social governance"in ecological environment in the countryside. It is thus suggested that in the governance of rural ecological environment,which is based on the social capital,the management space between the government and the community should be appropriately divided,so that the institutional capital can promote and regulate the social capital,enhance the construction of rural cooperative organizations and increase the input of rural human capital,and promote the coupling between administrative boundary and ecological boundary.展开更多

In particular, the existence of malicious node aggravates this contradiction. To resolve this contradiction, social relationship theory and group theory of social psychology were adopted to do an in-depth analysis. The concrete balancing approach which leveraged Nash equilibrium theory of game theory was proposed to resolve this contradiction in reality. Thus, a new congestion control routing algorithm for security defense based on social psychology and game theory (CRSG) was put forward. Through the experiment, this algorithm proves that it can enhance the message successful delivery ratio by more than 15% and reduce the congestion ratio over 15% as well. This algorithm balances the contradiction relationship between the two key performance targets and made all nodes exhibit strong cooperation relationship in DTN.展开更多

They have disputed whether the popular culture is the disaster or the blessedness for human beings and whether the popular culture is ideological or not,exploring the economic benefit and the social benefit of the popular culture,which provides enlightenment for the developm ent of the cultural industry of China. Firstly,we shall develop the cultural industry to satisfy the growing demand of the people for cultural products; secondly,with the development of the cultural industry,we shall balance the social benefit and economic benefit; finally,the socialist core value system is the necessity for the development of the cultural industry.展开更多
