This study examines critically major theories of information and offers an original treatment of information flows that attempts to remedy weaknesses in earlier treatments and may serve as a basis on which a satisfactory analysis of the concept of information can be developed.

We are surrounded by information. Even the most routine situations in which we find ourselves conceal a hidden information flow. Every step we take, a host of signals meet us, providing information about what is happening in other parts of reality. The cherry tree in bloom reveals that spring has arrived. The footprint left on wet sand indicates that someone has walked along the beach. A red traffic light signals that we must bring our car to a halt. In The Phenomenon of Information, author Mario Pérez-Montoro addresses the problems of providing a theoretical explanation of how a signal carries informational content, how to identify its characteristics, and how to define the mechanisms for describing it. To do this, Pérez-Montoro examines several theoretical approaches to the phenomenon of information: the mathematical theory of communication, Dretske's approach, and the relational theory of meaning. A critique of these efforts leads to the author's definition of informational content, named "the extensional approach," which is designed to overcome the conceptual limitations of the previous theories. The author proposes that his definition might serve as a basis on which a satisfactory analysis of the concept of information can be developed.

Contrary to optimistic visions of a free internet for all, the problem of the ‘digital divide’ – the disparity between those with access to internet technology and those without – has persisted for close to twenty-five years. In this textbook, Jan van Dijk considers the state of digital inequality and what we can do to tackle it. Through an accessible framework based on empirical research, he explores the motivations and challenges of seeking access and the development of requisite digital skills. He addresses key questions such as: Does digital inequality reduce or reinforce existing, traditional inequalities? Does it create new, previously unknown social inequalities? While digital inequality affects all aspects of society and the problem is here to stay, Van Dijk outlines policies we can put in place to mitigate it. The Digital Divide is required reading for students and scholars of media, communication, sociology, and related disciplines, as well as for policymakers.

This book focuses on the development of a theory of info-dynamics to support the theory of info-statics in the general theory of information. It establishes the rational foundations of information dynamics and how these foundations relate to the general socio-natural dynamics from the primary to the derived categories in the universal existence and from the potential to the actual in the ontological space. It also shows how these foundations relate to the general socio-natural dynamics from the potential to the possible to give rise to the possibility space with possibilistic thinking; from the possible to the probable to give rise to possibility space with probabilistic thinking; and from the probable to the actual to give rise to the space of knowledge with paradigms of thought in the epistemological space. The theory is developed to explain the general dynamics through various transformations in quality-quantity space in relation to the nature of information flows at each variety transformation. The theory explains the past-present-future connectivity of the evolving information structure in a manner that illuminates the transformation problem and its solution in the never-ending information production within matter-energy space under socio-natural technologies to connect the theory of info-statics, which in turn presents explanations to the transformation problem and its solution. The theoretical framework is developed with analytical tools based on the principle of opposites, systems of actual-potential polarities, negative-positive dualities under different time-structures with the use of category theory, fuzzy paradigm of thought and game theory in the fuzzy-stochastic cost-benefit space. The rational foundations are enhanced with categorial analytics. The value of the theory of info-dynamics is demonstrated in the explanatory and prescriptive structures of the transformations of varieties and categorial varieties at each point of time and over time from parent–offspring sequences. It constitutes a general explanation of dynamics of information-knowledge production through info-processes and info-processors induced by a socio-natural infinite set of technologies in the construction–destruction space.

Boulding discusses the image as the key to understanding society and human behavior

Do Not Look Outside. No Not Make Noise. Do Not Look At The Sky.The world ends in silence as bizarre entities from outer space descend on the Earth. The survivors must learn to live by three simple rules because to so much as catch a glance of the entities is to die. As they struggle, they're also forced to confront human evil, and another, even more dire threat that has taken the opportunity presented by the apocalypse to take dominion over the Earth.

This book explains how information literacy (IL) is essential to the contemporary workplace and is fundamental to competent, ethical and evidence-based practice. In today’s information-driven workplace, information professionals must know when research evidence or relevant legal, business, personal or other information is required, how to find it, how to critique it and how to integrate it into one’s knowledge base. To fail to do so may result in defective and unethical practice which could have devastating consequences for clients or employers. There is an ethical requirement for information professionals to meet best practice standards to achieve the best outcome possible for the client. This demands highly focused and complex information searching, assessment and critiquing skills. Using a range of new perspectives, Information Literacy in the Workplace demonstrates several aspects of IL’s presence and role in the contemporary workplace, including IL’s role in assuring competent practice, its value to employers as a return on investment, and its function as an ethical safeguard in the duty and responsibilities professionals have to clients, students and employers. Chapters are contributed by a range of international experts, including Christine Bruce, Bonnie Cheuk, Annemaree Lloyd with a foreword from Jane Secker. Content covered includes: examination of the value and impact of IL in the workplace how IL is experienced remotely, beyond workplace boundariesIL’s role in professional development organizational learning and knowledge creationdeveloping information professional competencieshow to unlock and create value using IL in the workplace. Readership: This book will be useful for librarians and LIS students in understanding how information literacy is experienced by professions they support; academics teaching professional courses; professionals (e.g. medical, social care, legal and business based) and their employers in showing that IL is essential to best practice and key to ethical practice.

This book deals with physiological, neurophysiological, and psychological aspects of the mechanisms and treatment of pain. It also provides information on the latest research results regarding the influence of age and gender on the perception of pain. Finally, it presents the basic mechanisms of analgesia in terms of pharmacological and nonpharmacological treatments.

The expanded companion book to the #1 documentary film about 2012! The 2012 meme has evolved beyond any debates about the relevance of the Maya Long Count calendar to the lives of contemporary human beings. 2012 is about us on planet Earth at this time. December 21, 2012: will the world really change forever on this date, the end of a 5,125-year calendar last used over a thousand years ago? Certainly Hollywood would like you to think so. Indeed, a not-so-small industry has arisen around the date, hawking everything from t-shirts to teleseminars. Clearing a path between fantasy and reality, Alexandra Bruce surveys the entire 2012 landscape, asking questions such as: Is the Earth losing its Mojo? How did 2012 come to mean "The End of Time"? Did psychedelics facilitate the Maya "Cosmovision"? Should we worry about Earth Crustal Displacement? What the hell is "Planet X"? Uniquely amongst a vast array of 2012 literature, this book features interviews with the leading experts—including Graham Hancock, John Major Jenkins, Daniel Pinchbeck and many others—and insightful, detailed analysis of the broad spectrum of opinion, debate, research and myth regarding the most compelling "end times" prediction of the 21st century.
