We think one important reason for this success has been that our book continues to offer a fresh and timely approach to computer networking instruction. We’ve made changes in this fifth edition, but we’ve also kept unchanged what we believe (and the instructors and students who have used our book have confirmed) to be the most important aspects of this book: its top-down approach, its focus…
“Big Data” [1] refers to datasets whose size is beyond the ability of typical database software tools to capture, store, manage, and analyze. There is a convergence of communications, sensing and computing towards the objective of achieving some control. In particular, cloud computing is promising. Sensors become cheaper. A network becomes bigger. In particular, powered by Internet protocol…
This volume, the second in the series produced by the Columbia Program on Indian Economic Policies, turns to the analysis of the reforms from a differ- ent viewpoint than the first. It takes as its starting point the fact that while the reforms have undoubtedly delivered in terms of poverty reduction and associated social objectives, the impact has not been as substantial as it has been in othe…
College students are relying on the Internet to make connections with other people every day (Lukianoff and Creeley, 2007; Verga, 2007; Hodge, 2006). As the Internet has developed and grown, so have the capabilities for inter- action. Social networking sites are a part of college students’ regular daily lives (Bugeja, 2006; Jones and Madden, 2002). With this new technology, questions about et…
"When it comes to looking for a job, it's not what you know, it's who you know." Well, there are a couple of major problems with that nugget of wisdom: If you know a lot of people, but they are not aware of (a) the collection of skills, experience and talent you offer or (b) the types of employment you are seeking, they can’t help you. If you know a lot of people, but you don’t h…
This paper presents the gSOAP stub and skeleton compiler. The compiler provides a unique SOAP-to-C/C++ language binding for deploying C/C++ applications in SOAP Web Services, clients, and peer-to-peer computing networks. gSOAP enables the integratation of (legacy) C/C++/Fortran codes, embedded systems, and real-time software in Web Services, clients, and peers that share computational resources…
Buttons and badges are a simple and cost-effective way to promote campaigns and short health messages to both partner organizations and individuals. By allowing individuals to post a badge or a button on their own site (which would then include a message and URL to the CDC.gov Web site for additional information), they become advocates for your campaign.
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…
