As a new wave in IT area,cloud computing provides a novel operation mode for e-government since it overcomes shortness of traditional e-government and meets requirements on intensification and opening.Whereas security risk is the major obstacle to develop and apply e-government cloud while related theories are insufficient.This paper introduced current situation of e-government cloud construction and intensive development mode of e-government in cloud environment,then focused on security risk factors the e-government faces up to based on reviewing security risks found by previous researches,and put forward corresponding coping strategies at last.

The Internet has entered the Web 3.0 age.The way of information transmission has a remarkable change.It becomes popular issues to study different ways to facilitate information sharing behavior and the influential factors of sharing behavior.Communication take a research on the effects the effects by metrology modeling while sociology studies certain specific category of information.Those studies lack either practicability or universality.In order to find out rules behind information sharing behavior,this study analyzed the information spreading rule on micro-blog based on conformity behavior perspective of communication theories.It conducted experiments by simulating micro-blog scenarios and asking subjects to choose which posts they want to repost.It turned out that three causes in conformity behavior—clustering scale,clustering cohesion and social status were also applicable in web information spreading.

Consumers make purchase decision based on the utility of merchandise.By perceived utility,the paper demonstrated the model of the attributes of store and product and deeply analyzed the impact of each variables.The research showed that the cost of each utility change trend to accordance for both the risk-appetite and risk-averse consumers while the rate of change varied widely.To be specific,for the risk-averse consumers,the cost of each sensitivity coefficient has impressive impact on the utility.On the contrary,for the risk-appetite consumers,their tolerance of risk dominate the cost of utility.In order to increasing the shops' perceived utility,the store should reduce the risk of shopping,adjustment cost and monitoring cost and lower the difficulty of searching relative commodity information.Inversely,improving the quality and urgent of goods only increase limited perceived utility since it will generate inhibitory effect in the meantime.

Health information is closely related to people's life quality,so the study on characteristics and influencers of health information adoption via SNS is of great significance.However research in this field is still in its infancy.Currently there is a lack of understanding on users' health information adoption behaviors via SNS.Combined with Social Cognitive theory and other research on health informatics,a new structural equation model was constructed to examine the domestic netizens' characteristics and motivations of health information adoption on Social Networking Sites.By exploratory and confirmatory factor analysis,the results showed that users' health self-efficacy,health concerns,perceived risk and perceived information support significantly influence the user adoption intention of SNS health information;meanwhile perceived information support,emotional support,health concerns,and perceived risk significantly affect the users' health self-efficacy;perceived risk was significantly influenced by users' propensity to trust.This study contributed some theoretical model on health information adoption by SNS to the future study,and provided reasonable advice for health related intervention.
