The Internet brings new possibilities to political communication and substantially expands traditional communication borders. Social networking websites, getting more and more popular every day, hold a prominent place in the lives of a large number of people. That is why politicians and parties are trying to use these websites as an additional tool of political communication. This article is dedicated to the analysis of possibilities of the use of social networking websites for political communication. It discusses detailed operation principles and categories of social networks, defines the reasons of their popularity and shortly presents social networking websites with the largest number of users in Lithuania and worldwide. The article explores in detail new possibilities for a spread of political information, speaks about the new ways of segmentation and personalization of political communication, created by virtual social networks. A research of Lithuanian politicians' communication using social networking sites is also presented. The research shows how politicians use social networking websites for election and continuous political communication.

Twitter and other micro-messaging services are catching fire as people realize these lightweight applications can be powerful tools to communicate, connect, and learn. With its potent mix of simplicity, utility, mobility, and sheer human appeal, micro-messaging is poised to become a major communications platform. This new O'Reilly Radar report reveals: - Best practices for micro-messaging in business- Pitfalls to avoid in this instant, very public medium- New methods for customer service and quick market research- How micro-messaging can help you reduce email and eliminate unproductive mee

Information flow during catastrophic events is a critical aspect of disaster management. Modern communication platforms, in particular online social networks, provide an opportunity to study such flow and derive early-warning sensors, thus improving emergency preparedness and response. Performance of the social networks sensor method, based on topological and behavioral properties derived from the "friendship paradox", is studied here for over 50 million Twitter messages posted before, during, and after Hurricane Sandy. We find that differences in users' network centrality effectively translate into moderate awareness advantage (up to 26 hours); and that geo-location of users within or outside of the hurricane-affected area plays a significant role in determining the scale of such an advantage. Emotional response appears to be universal regardless of the position in the network topology, and displays characteristic, easily detectable patterns, opening a possibility to implement a simple "sentiment sensing" technique that can detect and locate disasters. ; Yury Kryvasheyeu, Haohui Chen, Pascal Van Hentenryck and Manuel Cebrian acknowledge the support of the Australian Government represented by the Department of Broadband, Communications and Digital Economy; and the Australian Research Council through the ICT Centre of Excellence program.

Social capital's rise in popularity is a phenomenon many have noted (Kadushin, 2006; Warde and Tampubolon, 2002; Portes, 1998). Although the concept is a relatively old one, it is the works of Bourdieu (1986), Coleman (1988; 1990), and Putnam (1993, 2000) that often get credited for popularizing the concept. These three, while sharing a view that social networks are important for social groups and society, place differing levels of emphasis on the role of networks in building trust or the exchange of various types of resources. In this paper, I briefly revisit these three theorists, and the criticisms each have received, to provide background for discussing recent research on social capital from a social networks approach. The social network approach is then applied to my own case study looking at the relations among not-for-profits, and special attention is given to the unique context of not-for-profits, and how this context might elaborate or challenge current thoughts on social, aka 'network' capital. A final discussion is also given to some measurement problems with the network approach to social capital.
