Social networks, such as virtual communities, permit connections between citizen and government. Integrating consultative and deliberative environments for popular participation in democratic issues and creating virtual communities for warranting better relationship among members make it possible to model decisionmaking processes. For this reason, the Democratic Citizenship Community (DCC) was ...

On behalf of the Technical Program Committee, it is our pleasure to welcome you to the First IEEE Workshop on Performance and Management of Wireless and Mobile Networks. This workshop is held in conjunction with the 30 IEEE Conference on Local Computer Networks, LCN in Sydney, Australia. The co-location of this workshop will provide an excellent opportunity for the workshop participants to exch...

This paper proposes a context approach of social networks and virtual communities in the enterprise area. We point out that making context explicit it is possible to provide a global picture of the main aspects of social networks. A first result of this study is that the explicit consideration of contexts—especially shared contexts—could improve notably the collaborative-work processes in an en...

Modelling the diffusion of information is one of the key areas related to activity within social networks. In this field, there is recent research associated with the use of community detection algorithms and the analysis of how the structure of communities is affecting the spread of information. The purpose of this article is to examine the mechanisms of diffusion of viral content with particu...

This paper proposes a context-based approach of social networks and virtual communities in the enterprise area. We point out that making context explicit it is possible to provide a global picture of the main aspects of social networks. A first result of this study is that the explicit consideration of contexts—especially shared contexts—could improve notably the collaborative-work processes in...

This paper present the state of the art for the task 4 of the Kolflow project. This state of the art focuses on 3 notions: the notion of Traces and Trace Base Management Systems, the notion of Assistance and the notion of Virtual Communities and Social Networks. This state of the art is not a general study of these different concepts. It was done by studying different concepts in the context of...

Most Grid systems rely on their operating systems (OSs) to protect their sensitive files and networks. Unfortunately, modern OSs are very complex and it is difficult to completely avoid intrusions. Once intruders compromise the OS and gain system privilege, they can easily disable or bypass the OS security protections. This paper proposes a secure virtual Grid system, SVGrid, to protect sensiti...
