The present research examined how narcissism is manifested on a social networking Web site (i.e., Facebook.com). Narcissistic personality self-reports were collected from social networking Web page owners. Then their Web pages were coded for both objective and subjective content features. Finally, strangers viewed the Web pages and rated their impression of the owner on agentictraits, communal …
Social network web sites have become influential factors in how students communicate. In order to examine this phenomenon, HERI added a new item to the “time diary” section of the CIRP Your First College Year (YFCY) survey asking students how much time they typically spent each week on online social networking sites such as MySpace and Facebook.
Social networking sites have gained much popularity in the re- cent years, because of the opportunities they give people to connect to each other in an easy and timely manner, and to exchange and share various kinds of information. However, these sites are architected based on a cen- tralized paradigm, which limits the mobility of their users, and ultimately, their chances for establishing new …
A network is a set of devices (often referred to as nodes) connected by communication links that are built using different physical media. A node can be a computer, telephone, or any other device capable of sending and receiving messages. The communication medium is the physical path by which message travels from sender to receiver. Example media include fiber-optic cable, copper wire, or air c…
Social networking sites such as Facebook, MySpace and Twitter, are very popular with children, even those as young as 8 and 9. These types of sites allow children to be incredibly creative online, keep in touch with their friends and express themselves using a whole range of different media and applications such as video, photos, music, and chat.
An informant once said to us, “Man, you have to be crazy to use a gun to hold up a bank; those credit cards can get you the same thing with no risk.” Whether it be filling out fraudulent applications, stealing cards from the mail, or taking over legitimate accounts, it can be done — “You have to pick them though, watch out for the good banks; they’ve got systems to catch you if you …
Social media constitutes a group of online applications that encourages users to create content and interact with one another. Examples include blogs, social and professional networking sites like Facebook and LinkedIn, micro-blogging sites such as Twitter, media-sharing sites like YouTube and Flickr, social aggregation applications like Pinterest, and location-based sites like Foursquare. Some…
In this book we will propose new interdisciplinary directions for the study of global and regional problems and the interactions between these two scales. Today contemplating and addressing global and regional problems are bread and butter activities for many professionals interested in ‘international’ matters broadly conceived: academic analysts in several disciplines and fields, practisin…
Increased practical individual autonomy has been central to my claims throughout this book. It underlies the efficiency and sustainability of nonproprietary production in the networked information economy. It underlies the improvements I describe in both freedom and justice. Many have raised concerns that this new freedom will fray social ties and fragment social relations. On this view, the n…
In the aftermath of the global financial crisis, the European crisis and the recessions associated with these crises, one tends to think that the risk of deflation is greater than the risk of inflation as things stand at the end of 2012. This is a valid argument insofar as demand-pull factors and cost-push factors are associated with economic booms, when there is unutilized capacity in the econ…
Understanding how users behave when they connect to social networking sites creates opportunities for better interface design, richer studies of social interactions, and improved design of content distribution systems. In this paper, we present a first of a kind analysis of user workloads in on- line social networks. Our study is based on detailed click- stream data, collected over a 12-day pe…
The increasing use of derivatives for risk management of a company lately has led to the need to report on an actual basis as these instruments and regulate these operations accounting. This paper proposes a presentation of hedging transactions and their accounting evaluating the impact, in terms of accounting, risk management derivatives on a company. Hedges are often ineffective. Overcoming t…
The wide-scale financial crisis of recent years has focused attention on the role of central banks in achieving and maintaining financial stability. Indeed, financial stability was the primary reason for the establishment of many of the earliest central banks. But as financial crises diminished in frequency and severity in the post-World War II period, particularly in industrial coun- tries, ce…
Ambient Intelligence (AmI) has recently emerged as a vibrant research endeavor shaping our view of future computing and its role in society. While the inception point of AmI could always be argued about, it becomes apparent today that AmI has emerged and established itself as a result of a vivid synergy between several essential components such as- ubiquitous or pervasive computing, intelligent…
The question may be asked, why is it important to discuss good govern- ance as a prerequisite for sustainable and environmentally friendly development? The answer to the above question lies in the historical experience of failure to achieve economic growth by many countries of Africa, Asia and Latin America in the past several decades. Since the end of World War II, the economic literature o…
European social democracy needs to be shaken out of the defensive posture to which it has shrunk for several years now. It should not be in this position at all. Inequality is again becoming a major issue; the power of large corporations is producing a growing number of problems for consumers, workers and citizens; the neglect of collective needs is producing frightening problems of environment…
Have you watched a blockbuster on Netflix, bought a gadget on Amazon.com, or synced files with Dropbox today? If so, you’ve used Amazon Web Services (AWS) in the background. As of December 2014, AWS operated 1.4 mil- lion servers and therefore is a big player in the cloud computing market. The data centers of AWS are distributed throughout the United States, Europe, Asia, and South America. B…
Wireless networking is widely used in everybody’s daily lives. Nevertheless, not everyone has considered the reasons for such increasing utilization and nor have they understood the consequences. In this introduction, we provide a brief background regarding wireless networking evolution and the main scenarios where these networks are currently deployed.
In this paper, we survey recent work on peer-to-peer systems, and venture some opinions about future requirements for research. The paper is a survey to support the tutorial at the Networks 2002 Conference and is therefore neither complete, nor likely to be up-to-date by the time you are reading this, since the topic was extremely fast- evolving at the time of writing. Instead, we try to bring …
