A social networking phenomenon has emerged over the past five years. In that time, social networking sites (SNS) have grown from a niche to a mass online activity, in which tens of millions of internet users are engaged, both in their leisure time, and at work. However, there has been very little research on the socio-economic impact of these sites in the European context. This report presents…
“Social media is a term used to describe the type of media that is based on conversation and interaction between people online. Social media are media designed to be disseminated through social interaction, using highly accessible and scalable publishing techniques. ” - Wikipedia For almost two decades, the web has changed the world and revolutionized how information is stored, published…
Social networking sites (SNS) affordances for persistent interaction, collective generation of knowledge, and formation of peer-based clusters for knowledge sharing render them useful for developing constructivist knowledge environments. However, notwithstanding their academic value, these environments are not necessarily insulated from the exercise of academic/ power. Despite a growing corpus …
A growing number of kids at increasingly younger ages are engaging in online social networking today—a development that is leading to a surge of news stories, media attention, and economic investment. These shifts in usage and public discussion demand a better understanding of the ways that social networking sites mediate kids’ socializing and the opportunities and limits they place on kids…
Industry experience indicates that the ability to incre- mentally expand data centers is essential. However, ex- isting high-bandwidth network designs have rigid struc- ture that interferes with incremental expansion. We present Jellyfish, a high-capacity network interconnect which, by adopting a random graph topology, yields it- self naturally to incremental expansion. Somewhat sur- prisingly…
This book contains primarily papers presented at the seminar held at the inauguration of the doctoral program in psychology in May 1994, at the University of Tromsø, which is the youngest university in Norway and the northernmost university in the world (if one discounts the university branch on Svalbard at 88 degrees north). In fact, the University of Tromsø is situated on a coastal island i…
The history of humanity is essentially linked to the management of the Earth s surface. In the beginning, unknown variables and the environment controlled the nature of human settlements. Today, as we approach the end of the second millennium, the uncontrolled expansion of human settlements is modifying the environment and seriously threatening the sustainability of the whole planet. Human acti…
In 2006, Lacanians from North America, South America, and Europe, gathered in Georgia, at the University of West Georgia and at Emory University for the seventh annual conference of the Affiliated Psycho- analytic Workgroups (APW) which was devoted to the topic of addictions as approached from a Lacanian psychoanalytic orientation. The conference participants explored the complexity of the prob…
Economic competition is global, focused, and unrelenting; there is no such thing as a “safe” job. Whatever it was that formed the basis of your state’s economy 50, 25, or even 10 years ago is now at risk; and whatever it is that is coming next is hard to see or define, let alone prepare for. This came home to me in the late 1990s when the bloom of the dot com bubble was beginning to fade…

If you have tried to exercise regularly and have failed, then this is your book. Why? Because this …
The success of most IT projects can be boiled down to how well they were planned, test- ed, and piloted. It is critical to the success of any IPv6 rollout to establish a lab and work through the network configurations, application deployment, operating system nuances, and management of the entire environment. The lessons learned from the lab directly translate into a more streamlined pilot. Eve…
This book is about the convergence of the Internet - the 'IP' of our title - with mobile - the '3G', as in 'third generation mobile phones'. The book largely focuses on technology - rather than commercial or user-oriented considerations, for example - and in particular on the network aspects. In other words, in terms of the list above, the book is about the final bullet: about bringing the netw…
As the plan to write this book began to develop, a few central points became immediately apparent. First, the concept of violence represents a vast collection of behaviors and cognitions within a theoretical domain whose parameters are extremely ambiguous. Of course, there are distinctions between the types of violence and their nature, which can be clearly articulated, but the causal and corre…
Bluetooth is a technology for short range wireless data and realtime two-way voice transfer providing data rates up to 3 Mb/s. It can be used to connect almost any device to another device. Bluetooth-enabled devices, such as mobile phones, headsets, PCs, laptops, printers, mice, and keyboards, are widely used all over the world. Already in 2006, the one billionth Bluetooth device was shipped, a…
Information storage is a central pillar of information technology. A large quantity of digital information is being created every moment by individual and corporate consumers of IT. This information needs to be stored, protected, optimized, and managed. Not long ago, information storage was seen as only a bunch of disks or tapes attached to the back of the computer to store data. Even today, o…
Telecommunications has been defined as a technology concerned with communicating from a distance, and we can categorize it in various ways. Figure 1.1 shows one possible view of the different sections of telecommuni- cations. It includes mechanical communication and electrical communica- tion because telecommunications has evolved from a mechanical to an electrical form using increasingly more …
Multimedia – an interactive presentation of speech, audio, video, graphics, and text, has become a major theme in today’s information technology that merges the practices of commications, computing, and information processing into an interdisciplinary field. In recent years, there has been a tremendous amount of activity in the area of multimedia communications: applications, middleware, a…
In this paper, we present a horizontal view of social influence, more specifically a quantitative study of the in- fluence of neighbours on the probability of a particular node to join a group, on four popular Online Social Networks (OSNs), namely Orkut, YouTube, LiveJournal, and Flickr. Neighbours in OSNs have a mutually acknowledged relation, most often defined as friendship, and they are…
The concept. Manufacturing industries worldwide are facing tough challenges as a consequence of the globalization of economy and the openness of the markets. Progress of the economic blocks such as the European Union, NAFTA, and MERCOSUR, and the global agreements such as GATT, in addition to their obvious economic and social consequences, provoke strong paradigm shifts in the way that the manu…

In this paper we produce an algorithm for pre- senting messages to users in social networks that integrates reasoning about the message, the author, the recipient and the social network. Our proposed model was derived on the basis of immersion within three different existing social networking environments, that of Coursera, Reddit, and medical self-help groups such as PatientsLikeMe. We first …
