The degree distribution of this network model follows P（k） k-γ with y = 1. It means the network model has a power-law distribution. Through calculating the clustering coefficients and average path length （APL）, the result reflects that the model has the properties of high clustering coefficients and low APL.展开更多

Investigated the use intensity and addiction of SNSs among college students, with variables of use behaviors and online social support are relate to their online social skills and offline social skills. Seven point Likert scale, descriptive statistics, One-way ANOVA and logistic regression were used to determine the correlations of different use intensities and levels of addiction. The results explored whether college students＇ online social skills, offline social skills, and online social support are correlated with use intensity and addiction. Long-term or high-frequency use of SNSs does not lead to equivalent social relationships on SNSs, yet addiction to SNSs can reflect the positive support and communication ability of college students in online interpersonal relationships.展开更多

The current college ideological and political education has not paid enough attention to network education based on SNS, the position of network construction is lagging behind, the network Ideological and political education lack scientific planning, lack supervision power of social networking and other issues. This paper briefly introduced the University Network Ideological and political education pattern based on SNS, in order to effectively enhance the influence, attraction and control force of network Ideological and political education.展开更多

Cyworld was one of the most successful SNSs in the world, but its international expansion efforts failed. Facebook＇s open technology has had considerable influence on various sectors of the economy and society and allowed it to become a dominant SNS at the global level, whereas Cyworld has remained a local SNS. Facebook＇s open platform and application programming interface （API） pose a serious challenge to Cyworld＇s walled-garden approach. Cyworld is based on strong ties fostering close relationships, whereas Facebook expands social networks through its open and weak ties and has more network power than Cyworld. Therefore, openness is the main reason behind the rise of Facebook and the fall of Cyworld.展开更多
