Drawing on case studies from Denmark, The Netherlands and the UK, this book discusses new Information and Communication Technologies (ICTs). Contributors argue that ICTs play an important role in the process of restructuring and redefining basic relations within the political systems of Western democracies.

This issue represents a broad synopsis of the past, present, and future of electronic publishing. The contributors explore the opportunities and challenges related to this new distribution channel, and the effect of this change on publishers, authors/editors, distributors, and consumers. Standing with the key to the "new world," publishers will be faced with new opportunities and nagging issues related to new competition, content control, and protection of revenue streams requiring strategies that stress rationalization of distribution systems, cross-promotion, strategic pricing, and leveraging to new revenue sources. In addition, this issue also highlights the objections of consumers to these types of change, the benefits of the new technology for consumers, and the adaptation of the publishing industry as a whole.

We are often told that we are 'living in an information society' or that we are 'information workers'. But what exactly do these claims mean, and how might they be verified? In this important methodological study, Alistair Duff cuts through the rhetoric to get to the bottom of the 'information society thesis'.
Wide-ranging in coverage, this study will be of interest to scholars in information science, communication and media studies and social theory. It is a key text for the newly-unified specialism of information society studies, and an indispensable guide to the future of this discipline.

Heavy tails -extreme events or values more common than expected -emerge everywhere: the economy, natural events, and social and information networks are just a few examples. Yet after decades of progress, they are still treated as mysterious, surprising, and even controversial, primarily because the necessary mathematical models and statistical methods are not widely known. This book, for the first time, provides a rigorous introduction to heavy-tailed distributions accessible to anyone who knows elementary probability. It tackles and tames the zoo of terminology for models and properties, demystifying topics such as the generalized central limit theorem and regular variation. It tracks the natural emergence of heavy-tailed distributions from a wide variety of general processes, building intuition. And it reveals the controversy surrounding heavy tails to be the result of flawed statistics, then equips readers to identify and estimate with confidence. Over 100 exercises complete this engaging package.

This book is devoted to the development of optimal control theory for finite dimensional systems governed by deterministic and stochastic differential equations driven by vector measures. The book deals with a broad class of controls, including regular controls (vector-valued measurable functions), relaxed controls (measure-valued functions) and controls determined by vector measures, where both fully and partially observed control problems are considered. In the past few decades, there have been remarkable advances in the field of systems and control theory thanks to the unprecedented interaction between mathematics and the physical and engineering sciences. Recently, optimal control theory for dynamic systems driven by vector measures has attracted increasing interest. This book presents this theory for dynamic systems governed by both ordinary and stochastic differential equations, including extensive results on the existence of optimal controls and necessary conditions for optimality. Computational algorithms are developed based on the optimality conditions, with numerical results presented to demonstrate the applicability of the theoretical results developed in the book. This book will be of interest to researchers in optimal control or applied functional analysis interested in applications of vector measures to control theory, stochastic systems driven by vector measures, and related topics. In particular, this self-contained account can be a starting point for further advances in the theory and applications of dynamic systems driven and controlled by vector measures.

Following the emergence of quantum computing, the subsequent quantum revolution will be that of interconnecting individual quantum computers at the global level. In the same way that classical computers only realised their full potential with the emergence of the internet, a fully-realised quantum internet is the next stage of evolution for quantum computation. This cutting-edge book examines in detail how the quantum internet would evolve in practise, focusing not only on the technology itself, but also the implications it will have economically and politically, with numerous non-technical sections throughout the text providing broader context to the discussion. The book begins with a description of classical networks before introducing the key concepts behind quantum networks, such as quantum internet protocols, quantum cryptography, and cloud quantum computing. Written in an engaging style and accessible to graduate students in physics, engineering, computer science and mathematics.

This book addresses many of the issues facing new and seasoned communication and media administrators. Though there are business-oriented management and leadership books, there is no handbook--to the editor's knowledge--that emphasizes academic administration. This book fills an important gap in the literature by providing--in one place--interesting, important, and useful information that will help administrators by anticipating problems and suggesting strategies for the variety of challenges they face.
This scholarly, anecdotal, useful, and very readable volume is conceived as an action handbook that contains philosophical, theoretical, and practical information. It is divided into three sections: "background" material, "programmatic" challenges facing administrators, and "specific" challenges facing administrators. It contains information that both the seasoned administrator and those faculty who are thinking about moving into administration will find useful. Although aimed at the communication and media disciplines, administrators in other fields will also find it valuable. In addition, deans and vice presidents outside the discipline who are responsible for communication and media programs will view the book a "must" read.

The Soft Edge is a one-of-a-kind history of the information revolution. In his lucid and direct style, Paul Levinson, historian and philosopher of media and communications, gives us more than just a history of information technologies. The Soft Edge is a book about theories on the evolution of technology, the effects that human choice has on this (r)evolution, and what's in store for us in the future.
Boldly extending and deepening the pathways blazed by McLuhan, Paul Levinson has provided us with a brilliant and exciting study of life with our old media, our new media, and the media still to come.

Going Digital: Strategies for Access, Preservation, and Conversion of Collections to a Digital Format offers you succinct and analytic views of the problems and benefits of digital resources in the traditional academic library. Library administrators, collection managers, and librarians will learn the advantages and disadvantages of traditional and digital collections and the costs of providing local access or implementing remote access to digital collections. Originally presented at a series of five symposiums sponsored by the Research Libraries Group, the articles inGoing Digital will help you decide upon a cost-effective collection method that will meet the needs of your library, your patrons, and your budget.The chapters in this text are written by the nation 's leading librarians who pose and answer questions about hardware and software needed for digital libraries, the costs involved, establishing and maintaining access to digital collections, copyright concerns, and long-term preservation problems. Going Digital gives you insight into factors that will help you decide what will best meet the goals of your library, such as: the advantages and disadvantages of preserving microfilm and digital conversion choosing the correct hardware and software for your digital preservation program the changes required from librarians when shifting from collection development to digital resources examining the selection process for collections from perspectives of access, public service, technological requirements, and preservation ways to improve access to traditional collections cost comparisons between digital and hard copy resources devising a technical plan for successful digital conversion of projects involving the user 's wants when selecting collections for digital conversion and recognizing the central parts patrons play in the selection processIn light of the changing ways we receive and keep our information, Going Digital discusses new collection preservation criteria and suggests that access and informational values, not just deterioration, should be equal factors in selecting materials to be converted to digital form. Proving that digital collections are changing every facet of library operations, Going Digital shows you the most cost-effective way to begin a digital collection and how to choose what materials to digitize in order to provide your patrons with the information they want and need.

Information Theory is studied from the following points of view: (1) the theory of entropy as amount of information; (2) the mathematical structure of information sources (probability measures); and (3) the theory of information channels. Shannon entropy and Kolmogorov-Sinai entropy are defined and their basic properties are examined, where the latter entropy is extended to be a linear functional on a certain set of measures. Ergodic and mixing properties of stationary sources are studied as well as AMS (asymptotically mean stationary) sources.The main purpose of this book is to present information channels in the environment of functional analysis and operator theory as well as probability theory. Ergodic, mixing, and AMS channels are also considered in detail with some illustrations. In this second edition, channel operators are studied in many aspects, which generalize ordinary channels. Also Gaussian channels are considered in detail together with Gaussian measures on a Hilbert space. The Special Topics chapter deals with features such as generalized capacity, channels with an intermediate noncommutative system, and von Neumann algebra method for channels. Finally, quantum (noncommutative) information channels are examined in an independent chapter, which may be regarded as an introduction to quantum information theory. Von Neumann entropy is introduced and its generalization to a C*-algebra setting is given. Basic results on quantum channels and entropy transmission are also considered.

The true pioneers in electronic publishing put their bibliographic databases on tape and online in the 1960s. Nearly all of them had long experience with compiling information for distribution in printed form and a strong market connection. As a result of Soviet advances in science and space technology, American government support for information science and academic libraries flowed freely for a little over a decade, making possible tremendous advances in technology, in retrieval techniques and in sophisticated coverage. Advances in information technology and market conditions have encouraged many more participants to underwrite the development of databases that now extend into the arts, social sciences, business, and popular interests. These essays show how production statistics accompanied by statements of editorial coverage provide a fairly accurate reflection of output of many of the major disciplinary bibliographic databases. The urgent priority of information resources in the 1960s has encouraged comprehensive servicing of the formal research literature as published in journals and monographs. Authors have counted subject words, languages, origins, types of publication, and so on over several decades. This volume also includes articles on some databases that are not strictly bibliographic, such as the CMG database of college courses, which illuminates some of the changes in college textbook publishing. Information seekers will find the many tables of practical use, as guidance to what and how much may be found within each database. Analysts of publishing, of science policy, and of higher education will find information relevant to expenditures, human resources, and other indicators of education, research, and technology activity.

The chapters will benefit a diverse community of researchers. The book is suitable for graduate students, postdoctoral researchers and professors of various disciplines including sociology, physics, mathematics, and computer science.

The last two decades have seen the development of a number of models that have proven particularly important in advancing understanding of message-production processes. Now it appears that a "second generation" of theories is emerging, one that reflects considerable conceptual advances over earlier models. "Message Production: Advances in Communication Theory" focuses on these new developments in theoretical approaches to verbal and nonverbal message production. The chapters reflect a number of characteristics and trends resident in these theories including:
* the nature and source of interaction goals;
* the impact of physiological factors on message behavior;
* the prominence accorded conceptions of goals and planning;
* attempts to apply models of intra-individual processes in illuminating inter-individual phenomena;
* treatments which involve hybrid intentional/design-stance approaches; and
* efforts to incorporate physiological constructs and to meld them with psychological and social terms.
The processes underlying the production of verbal and nonverbal behaviors are exceedingly complex, so much so that they resist the development of unified explanatory schemes. The alternative is the mosaic of emerging theories such as are represented in this book -- each approach according prominence to certain message-production phenomena while obscuring others, and providing a window on some portion of the processes that give rise to those phenomena while remaining mute about other processes. The amalgam of these disparate treatments, then, becomes the most intellectually compelling characterization of message-production processes.

In an earlier era, the communication field was dominated by the study of mediated and unmediated message effects during which considerable research focused on the attitudinal and action consequences of exposure to messages. A more catholic purview of the communication process exists today. This more encompassing perspective does not deny the importance of studying message effects, but raises the additional question of how individuals generate messages in the first place. While the earlier era of communication research was dominated by studies that focused on attitude and behavior change as primary dependent variables, such variables as message comprehension have begun to emerge in this new era. The focus on communication and cognition has led, paradoxically, to a more intense focus on social interaction processes.
The theory and research presented in this volume seeks to strike a balance between the internal workings of the individual cognitive system on the one hand and the outer world of social interaction on the other. Whether or not the theory and research stands the test of time, it is clear that complete cognitive accounts of social interaction cannot confine themselves to mere descriptions of the cognitive structures and processes that are responsible for message production and comprehension. Explicit links must be made between these cognitive structures and processes and the workings of social interaction. This work takes a modest step in that direction.

This volume includes edited and revised versions of the papers delivered and discussed at the recent Advertising and Consumer Psychology Conference. Following the theme of the conference -- "Measuring Advertising Effectiveness" -- the book blends academic psychology, marketing theory, survey methodology, and practical experience, while simultaneously addressing the problems and limitations of advertising.
Acknowledging that advertisements are subtle, diverse, complex phenomena that require detailed investigation, this compilation explores the multidimensional nature of advertising's diverse effects from both academic and applied perspectives. Updates on theories and methods -- along with expert commentaries -- help to make this a valuable collection that will be of interest to advertising and marketing specialists and communications experts alike.
