"Google. Facebook. Twitter. Repeat. We live in a world unimaginable even a few decades ago, one like no other in human history. It's a parallel world where we can be on the move in the real world, yet always hooked into an alternative time and place. And although it's a two-dimensional world of sight and sound, it offers instant information, connected identities, and constant novelty. In this world, our screen technologies are increasingly where we work, where we unwind, where we relieve our boredom and where we learn. The subsequent transformation in how we live and think is a vitally important issue, perhaps even the most important issue of our time. When toddlers are given iPads, and adults spend ten hours a day staring at a screen, can we afford to assume that our brave new screen technologies are harmless tools? Blending a wide range of scientific studies, news events, and cultural criticism with brio and verve, Mind Change presents an incisive snapshot of the global 'now.' Greenfield examines how the dawn of the Digital Age has already altered our cultural landscape, fueled an epidemic of oversharing, and transformed how we learn, remember and spread information -- and how these innovations are changing our physical brains. A warning cry, a shot across the bow, and a call to action, Mind Change explores the social, cultural and physiological ramifications of our new digital lifestyle"--

"The media theorist who gave us the concepts of viral media, social currency and screenagers is back with his most far-reaching appraisal yet of digital media" --Cover, p. 4.

In these essays Heinz von Foerster discusses some of the fundamental principles that govern how we know the world and how we process the information from which we derive that knowledge. Included are path- breaking articles concerning the principles of computation in neural nets (1967), the definition of self-organizing systems (1960), the nature of cognition (1970), as well as recent expansions on these themes (e.g. "How recursive is communication," 1993). Working with Norbert Wiener, Warren McCullough, and others in the 1960s and 1970s, von Foerster was one of the founders of the science of cybernetics, which has had profound effects both on modern systems theory and on the philosophy of cognition. At the Biological Computer Laboratory at the University of Illinois he produced the first parallel computers and contributed to many other developments in the theory of computation and cognition.

A struggle is taking place--not just among corporate titans, but among entire industries. At stake is control of the world's fastest-growing industry: communications. The contestants are Hollywood studios, television networks, and cable, telephone, computer, publishing, and consumer-electronics companies. All are vying to collect a toll on the information superhighway. And as they jockey for control, they tread on volatile ground, as one fixation after another (cable, interactive TV) is dumped in favor of the next (satellite, the Internet). There is no better account of this turmoil than the one provided here by Ken Auletta, bestselling author of Three Blind Mice ("the best book ever written on network television"*) and Greed and Glory on Wall Street, who for five years has brilliantly tracked the communications industry for The New Yorker. Auletta's access to the principal players is unparalleled (six days with Rupert Murdoch, summit meetings with John Malone), and his grasp of the issues--from boardroom politics to regulatory and technological pressures--is unmatched by any other journalist. In this riveting collection of his best pieces Auletta takes the reader on a behind-the-scenes tour of such companies as Disney, Viacom, Microsoft, Time Warner, and Telecommunications, Inc., and keenly chronicles the vanities and visions of the new Highwaymen--Rupert Murdoch, Ted Turner, Michael Eisner, Sumner Redstone, Bill Gates, and more. Just as Three Blind Mice was heralded as "the new bible of the broadcasting business," The Highwaymen will be received as an indispensable guide to the future of this explosive new world. * Frank Stanton, former president of CBS

"The goal of this book is to help you better understand the juncture between computer technology and people, the process of creating that technology, and the evolution of those innovations. It does this through the use of essays and annotated case studies of people using technologies such as cell phones, blogs, and personal computer productivity tools"--p. [1]

Needing guidance and seeking insight, the Council of Europe approached Pierre Lévy, one of the world's most important and well-respected theorists of digital culture, for a report on the state (and, frankly, the nature) of cyberspace. The result is this extraordinary document, a perfectly lucid and accessible description of cyberspace-from infrastructure to practical applications-along with an inspired, far-reaching exploration of its ramifications. A window on the digital world for the technologically timid, the book also offers a brilliant vision of the philosophical and social realities and possibilities of cyberspace for the adept and novice alike. In an overview, Lévy discusses the distinguishing features of cyberspace and cyberculture from anthropological, philosophical, cultural, and sociological points of view. An optimist about the future potential of cyberspace, he eloquently argues that technology-and specifically the infrastructure of cyberspace, the Internet-can have a transformative effect on global society. Some of the issues he takes up are new art forms; changes in relationships to knowledge, education, and training; the preservation of linguistic and cultural differences; the emergence and implications of collective intelligence; the problems of social exclusion; and the impact of new technology on the city and democracy in general. In considerable detail, Lévy describes the ways in which cyberspace will help promote the growth of democracy, primarily through the participation of individuals or groups. His analysis is enlivened by his own personal impressions of cyberculture-garnered from bulletin boards, mailing lists, virtual reality demonstrations, andsimulations. Immediate in its details, visionary in its scope, deeply informed yet free of unnecessary technical language, Cyberculture is the book we require in our digital age. --Publisher.

The starting point of this volume was a conference entitled "Progress in Mathematical Programming," held at the Asilomar Conference Center in Pacific Grove, California, March 1-4, 1987. The main topic of the conference was developments in the theory and practice of linear programming since Karmarkar's algorithm. There were thirty presentations and approximately fifty people attended. Presentations included new algorithms, new analyses of algorithms, reports on computational experience, and some other topics related to the practice of mathematical programming. Interestingly, most of the progress reported at the conference was on the theoretical side. Several new polynomial algorithms for linear program- ming were presented (Barnes-Chopra-Jensen, Goldfarb-Mehrotra, Gonzaga, Kojima-Mizuno-Yoshise, Renegar, Todd, Vaidya, and Ye). Other algorithms presented were by Betke-Gritzmann, Blum, Gill-Murray-Saunders-Wright, Nazareth, Vial, and Zikan-Cottle. Efforts in the theoretical analysis of algo- rithms were also reported (Anstreicher, Bayer-Lagarias, Imai, Lagarias, Megiddo-Shub, Lagarias, Smale, and Vanderbei). Computational experiences were reported by Lustig, Tomlin, Todd, Tone, Ye, and Zikan-Cottle. Of special interest, although not in the main direction discussed at the conference, was the report by Rinaldi on the practical solution of some large traveling salesman problems. At the time of the conference, it was still not clear whether the new algorithms developed since Karmarkar's algorithm would replace the simplex method in practice. Alan Hoffman presented results on conditions under which linear programming problems can be solved by greedy algorithms.

Over the past years the author has developed a quantum language going beyond the concepts used by Bohr and Heisenberg. The simple formal algebraic language is designed to be consistent with quantum theory. It differs from natural languages in its epistemology, modal structure, logical connections, and copulatives. Starting from ideas of John von Neumann and in part also as a response to his fundamental work, the author bases his approach on what one really observes when studying quantum processes. This way the new language can be seen as a clue to a deeper understanding of the concepts of quantum physics, at the same time avoiding those paradoxes which arise when using natural languages. The work is organized didactically: The reader learns in fairly concrete form about the language and its structure as well as about its use for physics.
