Humans have been forming social networks since pre- historic times. The first networks were based around the family, clan, or tribe to ensure the survival of the group. In the Book of Numbers in the Old Testament, God instructs Moses how to organize the Hebrews and thus structure the nomads’ social interactions. Plato and Aristotle described the social structure of ancient Greece, and Alexand…
Models of networked diffusion that are motivated by analogy with the spread of infectious have been applied to a wide range of social and economic adoption processes, including those related to new products, ideas, norms and behaviors.
Social networking forms an important part of online activities of Web users. Web sites such as Facebook, MySpace and Orkut have millions of users using them everyday. However, these sites present two problems. Firstly, these sites form information silos. Information on one site is not usable in the others. Secondly such sites do not allow users much control over how their personal information i…
We present an end-to-end system that extracts a user’s social network and its members’ contact information given the user’s email inbox. The system identifies unique people in email, finds their Web presence, and automatically fills the fields of a contact address book using conditional random fields—a type of probabilistic model well-suited for such information extraction tasks. B…
A digital computer is a useful tool for solving a great variety of problems. A solution to a problem is called an algorithm; it describes the sequence of steps to be performed for the problem to be solved. A simple example of a problem and an algorithm for it would be: Problem: Sort a list of names in ascending lexicographic order. Algorithm: Call the given list list1; create an empty list, li…
The purpose of the networking guidelines are as follows: to assist students in understanding the benefits of networking to help students place in context their current stage of networking development in their school. to assist students in planning the next stage of network development in their school. to provide standard networking ‘models’ and best practice to studen…
I have known and used this book for years and I always found it very valu- able as a textbook for teaching computer networks as well as a reference book for networking professionals. This Fifth Edition maintains the core value of former editions and brings the clarity of explanation of network protocols in the introduction of the most up-to-date techniques, technolo- gies and requirements of ne…
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 …
