In this paper, we examine the use of an online social networking site by Michigan State University undergraduates and its relationship to social capital formation and maintenance, integration into college life, and psychological well-being. Facebook is an online social network software application used by university students to articulate existing offline social connections

Abstract: Keeping in touch with family and friends should be easier now that we have a repertoire of communication tools available to us (e.g. SMS, IM, email, mobile and landline phones). And yet many of us continue to find it difficult to maintain and manage our personal contacts. Why is this so? This paper describes a study that looked at how three different age groups manage their personal networks and what types of technology-mediated communication tools they use. Our findings were that older teenagers have the largest social networks and experience considerable contact management effort; that people around the age of 30 use the greatest variety of communication technology; and that people in their fifties have the smallest social networks consisting mainly of family and very close friends. Using qualitative data representations, we discuss our findings in terms of ways to more effectively support people to manage multiple modes of communication.

(Ghana). The approach taken in the analysis was developed in a series of meetings held at the National Center for Ecological Analysis and Synthesis in Santa Barbara during this same period of time. This group of ‘Bobcows ’ was convened by Edward Hackett to examine the process of scientific collaboration in a variety of forms. We based the present work on similar analyses by Barry Bozeman, Sooho Lee, John Walsh and Nancy Mahoney. However, our gratitude is first and foremost to the outstanding teams of postgraduate interviewers from Loyola College of Social Sciences (Kerala), the

Human-Computer Interaction (HCI) has devised many methods to support usercentred design (Mayhew, 1999; Nielsen, 1993). Nevertheless, there is an increasing need for design methods that support the unique set of requirements found in social software. We identify the key aspects of social software that distinguish it from nonsocial software and go on to describe a design lifecycle that has been successfully implemented in the design of a communication and contact management and visualisation tool prototype. The multidisciplinary team engaged in collaborative user-centred research and design. The techniques used to support this are described. Also discussed are the ways in which collaboration was facilitated, with a focus on the accommodation of the multidisciplinary nature of the team. The research findings suggested differences in social network size between age groups, as well as different methods of social network visualisation in both visual design and structure. The paper describes how each methodology in the lifecycle was conducted and lists the advantages and limitations of each, providing suggestions for improvements where possible. Scope for further work is discussed and a synopsis of the main findings is presented.

Previous research in Kyrgyzstan has demonstrated the importance of close social networks as avenues for gathering and sharing information, assistance and goods in the country. However, the relationship between technology use and social network use has not been investigated; understanding this relationship is important when considering the design of technology applications that support existing social networks. Contrary to Robert Putnam’s hypothesis that technologies have an ”individualizing ” force on populations, we have found that social network patterns do not appear to be negatively associated with higher technology use. In fact, the higher the level of technology use, the more face-to-face social networks were used for multiple types of information seeking. 1.

The fourth generation (4G) network paradigm has long been sought. A user-centric vision for such “always best connected ” next-generation 4G networks is neighborhood Wireless Mesh Networks (WMNs). The vision for WMNs reflects the tradeoff between the immediate selfinterest of the user, and the user’s need for social contacts: Users would pool their resources in order to support the creation and operation of the underlying communication network (participating at all physical, access, and network

During the past decade usage of online social network sites has grown dramatically, now rivaling search engines as the most visited Internet sites (Experian Hitwise, 2010). With the rise of such mega‐sites as Facebook, which by itself now boasts more than 400 million active users around the world (Facebook Press Room, 2010), online social network use has
