By one estimate, 90 percent of all of the data in history was created in the last two years. In 2014, International Data Corporation calculated the data universe at 4.4 zettabytes, or 4.4 trillion gigabytes. That much information, in volume, could fill enough slender iPad Air tablets to create a stack two-thirds of the way to the moon. Now, that's Big Data. Coal, iron ore, and oil were the key productive assets that fueled the Industrial Revolution. The vital raw material of today's information economy is data. In Data-ism, New York Times reporter Steve Lohr explains how big-data technology is ushering in a revolution in proportions that promise to be the basis of the next wave of efficiency and innovation across the economy. But more is at work here than technology. Big data is also the vehicle for a point of view, or philosophy, about how decisions will be—and perhaps should be—made in the future. Lohr investigates the benefits of data while also examining its dark side. Data-ism is about this next phase, in which vast Internet-scale data sets are used for discovery and prediction in virtually every field. It shows how this new revolution will change decision making—by relying more on data and analysis, and less on intuition and experience—and transform the nature of leadership and management. Focusing on young entrepreneurs at the forefront of data science as well as on giant companies such as IBM that are making big bets on data science for the future of their businesses, Data-ism is a field guide to what is ahead, explaining how individuals and institutions will need to exploit, protect, and manage data to stay competitive in the coming years. With rich examples of how the rise of big data is affecting everyday life, Data-ism also raises provocative questions about policy and practice that have wide implications for everyone. The age of data-ism is here. But are we ready to handle its consequences, good and bad?

Cyberspace is one of the major bases of the economic development of industrialized societies and developing. The dependence of modern society in this technological area is also one of its vulnerabilities. Cyberspace allows new power policy and strategy, broadens the scope of the actors of the conflict by offering to both state and non-state new weapons, new ways of offensive and defensive operations. This book deals with the concept of "information war", covering its development over the last two decades and seeks to answer the following questions: is the control of the information space really possible remains or she a utopia? What power would confer such control, what are the benefits?
You can measure practically anything in the age of social media, but if you don’t know what you’re looking for, collecting mountains of data won’t yield a grain of insight. This non-technical guide shows you how to extract significant business value from big data with Ask-Measure-Learn, a system that helps you ask the right questions, measure the right data, and then learn from the results. Authors Lutz Finger and Soumitra Dutta originally devised this system to help governments and NGOs sift through volumes of data. With this book, these two experts provide business managers and analysts with a high-level overview of the Ask-Measure-Learn system, and demonstrate specific ways to apply social media analytics to marketing, sales, public relations, and customer management, using examples and case studies.
The revitalisation of audience studies is not only about new approaches and methods; it entails a crossing of disciplines and a bridging of long-established boundaries in the field. The aim of this volume is to capture the boundary-crossing processes that have begun to emerge across the discipline in the form of innovative, interdisciplinary interventions in the audience research agenda. Contributions to this volume seek to further this process though innovative, audience-oriented perspectives that firmly anchor media engagement within the diversity of contexts and purposes to which people incorporate media in their daily lives, in ways often unanticipated by industries and professionals.
A new approach to investing based on how Wall Street insidersapproach the market The Indomitable Investor deconstructs the stock market asthe public has come to know it and reconstitutes it from the insideout from the perspective of the fortunate few who dominate WallStreet. By revealing how top investors and traders think and actSteven Sears shows the stock market to be an undulating ocean ofmoney, with seasoned investors reading the waves others cannot. Teaching readers to think about the market in radicallydifferent ways, The Indomitable Investor shows how toimprove returns—and, just as importantly, avoidlosses—with disciplines deployed by people who almost alwaysdo exactly the opposite of what Wall Street says to do. Laying bare great fallacies, the book explains thatnon-professional investors wrongly think the stock market is aplace to make money, which is what Wall Street wants them to try todo. The Indomitable Investor says otherwise and shows howWall Street's best investors have a completely different focus. Explains the critical ideas and insights of top traders andinvestors in language anyone can understand and implement Packed with material rarely shared off Wall Street that is usedevery day by professional investors Introduces the 17 most important words on Wall Street Teaches critical skills, including: How to increase returns byfocusing on risk, not potential profits; how to use the stockmarket's historical patterns to optimize investment decisions;understanding key relationships between stocks and the economy thatpredict what will happen to stocks and the broader market; how toincrease mutual fund returns with an easy adjustment that redirectsthe bulk of profits to you—not mutual fund companies, and howto analyze information like seasoned investors to move beyond"statement of the obvious" news reports that turn ordinaryinvestors into Dumb Money Accessible to readers of all backgrounds, including those with alimited understanding of investing, The Indomitable Investorwill change how investors view the stock market, Wall Street, andthemselves.
A new foundation for information system development is required in order to facilitate systems with a better organizational fit, increased user friendliness and improved flexibility. This study describes an integrated approach to business and information system development that permits this. The specification framework developed enables vertical integration of business, user and developer modelling worlds, as well as horizontal integration of data, behaviour and process perspectives. Both forms of integration are addressed on the basis of an object oriented approach, with an underlying mathematical foundation in high level Petri nets. On the basis of this theory, integrated CASE tools can provide new ways of visualizing and manipulating specification models. Model execution permits simulation and testing of business activities, user interface and system design by means of interactive graphical animation.
Data Communication Principles for Fixed and Wireless Networks focuses on the physical and data link layers. Included are examples that apply to a diversified range of higher level protocols such as TCP/IP, OSI and packet based wireless networks. Performance modeling is introduced for beginners requiring basic mathematics. Separate discussion has been included on wireless cellular networks performance and on the simulation of networks. Throughout the book, wireless LANS has been given the same level of treatment as fixed network protocols. It is assumed that readers would be familiar with basic mathematics and have some knowledge of binary number systems. Data Communication Principles for Fixed and Wireless Networks is for students at the senior undergraduate and first year graduate levels. It can also be used as a reference work for professionals working in the areas of data networks, computer networks and internet protocols.
