divThe Internet has changed our social spaces, our political and social realities, our use of language, and the way we communicate, all with breathtaking speed. Almost everyone who deals with the Internet and the new world of cyberspace communication at times feels bewildered, dismayed, or even infuriated. In this clear and helpful book, computer communications scholar Laura J. Gurak takes a close look at the critical issues of online communication and discusses how to become literate in the new mass medium of our era. In cyberspace, Gurak shows us, literacy means much more than knowing how to read. Cyberliteracy means being able to sort fact from fiction, to detect extremism from reasonable debate, and to identify gender bias, commercialism, imitation, parody, and other aspects of written language that are problematic in online communication. Active reading skills are essential in cyberspace, where hoaxes abound, advertising masquerades as product information, privacy is often compromised, and web pages and e-mail messages distort the truth. Gurak analyzes the new language of the Internet, explaining how to prepare for its discourse and protect oneself from its hazards. This book will appeal to anyone with an interest in the impact of the Internet on the practices of reading and writing and on our culture in general./DIV

Brain Theory From A Circuits And Systems Perspective

This book models an idealized neuron as being driven by basic electrical elements, the goal being to systematically characterize the logical properties of neural pulses. In order to constitute a system, neurons as pulsating devices may be represented using novel circuit elements as delineated in this book. A plausible brain system is implied by the delineated elements and logically follows from known and likely properties of a neuron. New to electrical science are novel pulse-related circuit elements involving recursive neurons. A recursive neuron, when properly excited, produces a self-sustaining pulse train that when sampled, provides a true output with a specified probability, and a false output with complementary probability. Because of its similarity to the qubits of quantum mechanics, the recursive pulsating neuron is termed a simulated qubit. Recursive neurons easily function as controlled toggle devices and so are capable of massively parallel calculations, this being a new dimension in brain functioning as described in this book. Simulated qubits and their possibilities are compared to the qubits of quantum physics. Included in the book are suggested neural circuits for associative memory search via a randomized process of cue selection, and neural circuits for priority calculations. These serve to select returns from long term memory, which in turn determines one's next conscious thought or action based on past memorized experiences. The book reports on proposals involving electron tunneling between synapses, and quantum computations within neurons. Although not a textbook, there are easy exercises at the ends of chapters, and in the appendix there are twelve simulation experiments concerning neurons. ​

This thoroughly updated version of the German authoritative work on self-organization has been completely rewritten by internationally renowned experts and experienced book authors to also include a review of more recent literature. It retains the original enthusiasm and fascination surrounding thermodynamic systems far from equilibrium, synergetics, and the origin of life, representing an easily readable book and tutorial on this exciting field. The book is unique in covering in detail the experimental and theoretical fundamentals of self-organizing systems as well as such selected features as random processes, structural networks and multistable systems, while focusing on the physical and theoretical modeling of natural selection and evolution processes. The authors take examples from physics, chemistry, biology and social systems, and include results hitherto unpublished in English. The result is a one-stop resource relevant for students and scientists in physics or related interdisciplinary fields, including mathematical physics, biophysics, information science and nanotechnology.

The concept of temporal networks is an extension of complex networks as a modeling framework to include information on when interactions between nodes happen. Many studies of the last decade examine how the static network structure affect dynamic systems on the network. In this traditional approach the temporal aspects are pre-encoded in the dynamic system model. Temporal-network methods, on the other hand, lift the temporal information from the level of system dynamics to the mathematical representation of the contact network itself. This framework becomes particularly useful for cases where there is a lot of structure and heterogeneity both in the timings of interaction events and the network topology. The advantage compared to common static network approaches is the ability to design more accurate models in order to explain and predict large-scale dynamic phenomena (such as, e.g., epidemic outbreaks and other spreading phenomena). On the other hand, temporal network methods are mathematically and conceptually more challenging. This book is intended as a first introduction and state-of-the art overview of this rapidly emerging field.

The primary purpose of this book is to trace the theoretical methodological foundations of American educational technology. It must be emphasized that this work is essentially as history of the process of educational technology rather than of products in the form of devices or media. Although media have played an important rode in educational technology, the reader should not lose sight of the central process which characterizes and underlies the true historical meaning and function of educational technology. Moreover, the assumption is made that all current theory, methodology, and practice rests upon the heritage of the past. Indeed, a common problem in the field has been the failure, in many instances, to take adequate account of past history in planning for the present or the future. A related purpose of this book is to provide a selective survey of research in educational technology as it relates to the American public schools. Such research reviews are not intended to be comprehensive, but were included because of their historical importance and their relevance in understanding the process of educational technology.

microRNAs (miRNAs) are small non-coding RNAs that regulate various biological phenomena, such as development and homeostasis. The dysregulation of miRNA leads to disease progression, particularly of cancer. In Circulating MicroRNAs: Methods and Protocols, expert researchers in the field detail recent advances in the isolation, purification and analysis of circulating miRNAs from a variety of sources for research. The book is divided into three main topics. The first section involves the study of secretory miRNAs in cell-cell communication, and the second, the study of circulating miRNAs in body fluids. The last describes the novel techniques used to study circulating miRNAs. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Circulating MicroRNAs: Methods and Protocols seeks to aid scientists in dealing with the recent advances of RNAi technology from the bench to the bedside.

Our world is, increasingly, a digital one. Over half of the planet’s adult population now spend more of their waking hours ‘plugged in’ than not, whether to the internet, mobile telephony, or other digital media. To email, text, tweet and blog our way through our careers, relationships and even our family lives is now the status quo. But what effect is this need for constant connection really having? For the first time, Tom Chatfield examines what our wired life is really doing to our minds and our culture - and offers practical advice on how we can hope to prosper in a digital century. One in the new series of books from The School of Life, launched May 2012: How to Stay Sane by Philippa Perry How to Find Fulfilling Work by Roman Krznaric How to Worry Less About Money by John Armstrong How to Change the World by John-Paul Flintoff How to Thrive in the Digital Age by Tom Chatfield How to Think More About Sex by Alain de Botton
