It includes the definitions of one-thousand terms.
Описание: Ethical dilemmas have risen in number and intensity with the increasing dependence of contemporary society on computers and computer networks. Despite the proliferation of expert remedies, viable solutions to computer security issues remain too elusive, and society continues to suffer at the hands of cyber criminals, vandals, and hackers.This comprehensive third edition of the successful Ethical and Social Issues in the Information Age takes off where the second ended to examine ethical, social, and policy challenges stemming from the emergence of cyberspace, the convergence of telecommunication and computing technologies, and the miniaturalization of computing, telecommunication, and information-enabling devices. This accessible volume broadly surveys thought-provoking questions about the impact of these new technologies, with particular emphasis on the rapid growth of a multitude of computer networks, including the Internet. It assumes only a very modest familiarity with the basic computer literacy.Topics and features:вЂў Describes how changes in information technology influence morality and the lawвЂў Provides fundamental discussion of network-security system design and operation to reveal vulnerable areas in computer network infrastructure (NEW chapter)вЂў Surveys the history of computing and the evolution of computer crimesвЂў Explores biometric techniques to system access control (NEW chapter)вЂў Incorporates recent requirements for computer curriculaвЂў Introduces and explores techniques in electronic crime investigation (NEW chapter)вЂў Assesses workplace concerns related to privacy, surveillance, and virtual officesвЂў Offers a pertinent discussion on civil liberties, harassment, and discriminationвЂў Contains chapter-ending exercises, and the author provides instructor classroom support materials and teaching guides at his websiteThis newly revised text/reference provides an updated discussion of the ethical and social issues that continue to evolve as computing and information technologies proliferate. Students at all levels who need to learn about computer ethics, the legal aspects of computing, network security, computer crime investigation, and biometrics will find this well documented work an invaluable resource. The book is also highly useful for practitioners needing such insights for their work.Supplementary material can be found at: www.utc.edu/faculty/Joseph-Kizza
Описание: New Directions in Human Information Behavior, co-edited by Drs. Amanda Spink and Charles Cole provides an understanding of the new directions, leading edge theories and models in human information behavior. Information behavior is conceptualized as complex human information related processes that are embedded within an individualвЂ™s everyday social and life processes.The book presents chapters by an interdisciplinary range of scholars who show new directions that often challenge the established views and paradigms of information behavior studies. Beginning with an evolutionary framework, the book examines information behaviors over various epochs of human existence from the Palaeolithic Era and within pre-literate societies, to contemporary behaviors by 21st century humans. Drawing upon social and psychological science theories the book presents a more integrated and holistic approach to the understanding of information behaviors that include multitasking and non-linear longitudinal processes, individualsвЂ™ information ground, information practices and information sharing, digital behaviors and human information organizing behaviors. The final chapter of the book integrates these new approaches and presents an overview of the key trends, theories and models for further research.This book is directly relevant to information scientists, librarians, social and evolutionary psychologists. Undergraduate and graduate students, academics and information professionals interested in human information behavior will find this book of particular benefit.

Описание: This book explains the way in which information and knowledge are treated in contemporary economic theories and, therefore, contributes to our understanding of the importance of the strategic organisation of information and the acquisition of know-how to the behaviour of modern economies. It gathers together contributions of experts on the role of information in the various theories covered: specifically, in system analysis, in game theory, in the 'statistical theory of information', in theories of market pricing, of financial speculation and of bounded rationality decision making, in the evolutionary theory of the firm, in the 'new industrial economics' and in the 'economics of codification'. Economics and Information is divided into three parts. Part One deals with general theories of information. Part Two addresses the role of information in the functioning of markets. Part Three considers the importance of information to the operation of organisations. Conclusions are drawn in Part Four on the implications for the process of economic growth and for economic policies. It, therefore, provides new insights into some of the puzzling features of recent developments in the so called New Economy.
Описание: This book is an introduction to the mathematical description of information in science and engineering. The necessary mathematical theory will be treated in a more vivid way than in the usual theorem-proof structure. This enables the reader to develop an idea of the connections between different information measures and to understand the trains of thought in their derivation. As there exist a great number of different possible ways to describe information, these measures are presented in a coherent manner. Some examples of the information measures examined are: Shannon information, applied in coding theory; Akaike information criterion, used in system identification to determine auto-regressive models and in neural networks to identify the number of neurons; and Cramer-Rao bound or Fisher information, describing the minimal variances achieved by unbiased estimators. This softcover edition addresses researchers and students in electrical engineering, particularly in control and communications, physics, and applied mathematics.
Описание: Provides an introduction to coding theory and information theory for undergraduates of mathematics and computer science. It discusses the topics such as: a review of probability theory; the efficiency of codes, the capacity of communications channels, coding and decoding in the presence of errors, the general theory of linear codes, and more.

Описание: An interdisciplinary discussion of the phenomenon of life, including its origin and evolution (and also human cultural evolution), against the background of
thermodynamics, statistical mechanics, and information theory. Among the central themes is the seeming contradiction between the second law of thermodynamics and the high degree
of order and complexity produced by living systems. This paradox has its resolution in the information content of the Gibbs free energy that enters the biosphere from outside sources, as
the author shows.
The role of information in human cultural evolution is another focus of the text. One of the final chapters discusses the merging of information technology
and biotechnology into a new discipline - bio-information technology.

Автор: Robert McEliece Название: The Theory of Information and Coding ISBN: 0521000955 ISBN-13(EAN): 9780521000956 Издательство: Cambridge Academ Рейтинг: Цена: 17667 р. Наличие на складе: Поставка под заказ.
Описание: This is a revised edition of McEliece’s classic. It is a self-contained introduction to all basic results in the theory of information and coding (invented by Claude Shannon in 1948). This theory was developed to deal with the fundamental problem of communication, that of reproducing at one point, either exactly or approximately, a message selected at another point. There is a short and elementary overview introducing the reader to the concept of coding. Then, following the main results, the channel and source coding theorems, there is a study of specific coding schemes which can be used for channel and source coding. This volume can be used either for self-study, or for a graduate/undergraduate level course at university. It includes dozens of worked examples and several hundred problems for solution. The exposition will be easily comprehensible to readers with some prior knowledge of probability and linear algebra.

Описание: Information Theory, Evolution and the Origin of Life presents a timely introduction to the use of information theory and coding theory in molecular biology. The genetical information system, because it is linear and digital, resembles the algorithmic language of computers. George Gamow pointed out that the application of Shannon's information theory breaks genetics and molecular biology out of the descriptive mode into the quantitative mode and Dr Yockey develops this theme, discussing how information theory and coding theory can be applied to molecular biology. He discusses how these tools for measuring the information in the sequences of the genome and the proteome are essential for our complete understanding of the nature and origin of life. The author writes for the computer competent reader who is interested in evolution and the origins of life.
