Book Description
In the early 1990s, people predicted the death of privacy, an end to the current concept of 'property, ' a paperless society, 500 channels of high-definition interactive television, world peace, and the extinction of the human race after a takeover engineered by intelligent machines. Imagining the Internet zeroes in on predictions about the Internet's future and revisits past predictions--and how they turned out. It gives the history of communications in a nutshell, illustrating the serious impact of pervasive networks and how they will change our lives over the next century.

Book Description
This book is an impressive survey of our collective and cumulative understanding of the evolution of digital communication systems and the Internet. Whilst the information societies of the twenty-first century will develop ever more sophisticated technologies, the Internet is now a familiar and pervasive part of the world in which we live, work, and communicate. As such it is important to take stock of some fundamental questions - whether, for example, it contributes to progress, social cohesion, democracy, and growth - and at the same time to review the rich and varied theories and perspectives developed by thinkers in a range of disciplines over the last fifty years or more. In this remarkably comprehensive but concise and useful book, Robin Mansell summarizes key debates, and reviews the contributions of major thinkers in communication systems, economics, politics, sociology, psychology, and systems theory - from Norbert Wiener to Brian Arthur and Manuel Castells, and from Gregory Bateson to William Davidow and Sherry Turkle. This is an interdisciplinary and critical analysis of the way we experience the Internet in front of the screen, and of the developments behind the screen, all of which have implications for privacy ,security, intellectual property rights, and the overall governance of the Internet. The author presents fairly the ideas of the celebrants and the sceptics, and reminds us of the continuing need for careful, critical, and informed analysis of the paradoxes and challenges of the Internet, offering her own views on how we might move to greater empowerment, and suggesting policy measures and governance approaches that go beyond those commonly debated. This concise book will be essential reading for anyone who wants to understand the challenges the Internet presents in the twenty-first century, and the debates and research that can inform that understanding.

Book Description
Big Digital Humanities has its origins in a series of seminal articles Patrik Svensson published in the Digital Humanities Quarterly between 2009 and 2012. As these articles were coming out, enthusiasm around Digital Humanities was acquiring a great deal of momentum and significant disagreement about what did or didn’t “count” as Digital Humanities work. Svensson’s articles provided a widely sought after omnibus of Digital Humanities history, practice, and theory. They were informative and knowledgeable and tended to foreground reportage and explanation rather than utopianism or territorial contentiousness. In revising his original work for book publication, Svensson has responded to both subsequent feedback and new developments. Svensson’s own unique perspective and special stake in the Digital Humanities conversation comes from his role as director of the HUMlab at Umeå University. HUMlab is a unique collaborative space and Digital Humanities center, which officially opened its doors in 2000. According to its own official description, the HUMlab is an open, creative studio environment where “students, researchers, artists, entrepreneurs and international guests come together to engage in dialogue, experiment with technology, take on challenges and move scholarship forward.” It is this last element “moving scholarship forward” that Svensson argues is the real opportunity in what he terms the “big digital humanities,” or digital humanities as practiced in collaborative spaces like the HUMlab, and he is uniquely positioned to take an account of this evolving dimension of Digital Humanities practice.

Book Description
In Internet for the People, leading tech writer Ben Tarnoff offers an answer. The internet is broken, he argues, because it is owned by private firms and run for profit. Google annihilates your privacy and Facebook amplifies right-wing propaganda because it is profitable to do so. But the internet wasn't always like this-it had to be remade for the purposes of profit maximization, through a years-long process of privatization that turned a small research network into a powerhouse of global capitalism. Tarnoff tells the story of the privatization that made the modern internet, and which set in motion the crises that consume it today. The solution to those crises is straightforward: deprivatize the internet. Deprivatization aims at creating an internet where people, and not profit, rule. It calls for shrinking the space of the market and diminishing the power of the profit motive. It calls for abolishing the walled gardens of Google, Facebook, and the other giants that dominate our digital lives and developing publicly and cooperatively owned alternatives that encode real democratic control. To build a better internet, we need to change how it is owned and organized. Not with an eye towards making markets work better, but towards making them less dominant. Not in order to create a more competitive or more rule-bound version of privatization, but to overturn it. Otherwise, a small number of executives and investors will continue to make choices on everyone's behalf, and these choices will remain tightly bound by the demands of the market. It's time to demand an internet by, and for, the people now.

Book Description
Based on a series of case studies of globally distributed media and their reception in different parts of the world, Imagining the Global reflects on what contemporary global culture can teach us about transnational cultural dynamics in the 21st century. A focused multisited cultural analysis that reflects on the symbiotic relationship between the local, the national, and the global, it also explores how individuals’ consumption of global media shapes their imagination of both faraway places and their own local lives. Chosen for their continuing influence, historical relationships, and different geopolitical positions, the case sites of France, Japan, and the United States provide opportunities to move beyond common dichotomies between East and West, or United States and “the rest.” From a theoretical point of view, Imagining the Global endeavors to answer the question of how one locale can help us understand another locale. Drawing from a wealth of primary sources—several years of fieldwork; extensive participant observation; more than 80 formal interviews with some 160 media consumers (and occasionally producers) in France, Japan, and the United States; and analyses of media in different languages—author Fabienne Darling-Wolf considers how global culture intersects with other significant identity factors, including gender, race, class, and geography. Imagining the Global investigates who gets to participate in and who gets excluded from global media representation, as well as how and why the distinction matters.

Book Description
A History of the Internet and the Digital Future tells the story of the development of the Internet from the 1950s to the present and examines how the balance of power has shifted between the individual and the state in the areas of censorship, copyright infringement, intellectual freedom, and terrorism and warfare. Johnny Ryan explains how the Internet has revolutionized political campaigns; how the development of the World Wide Web enfranchised a new online population of assertive, niche consumers; and how the dot-com bust taught smarter firms to capitalize on the power of digital artisans. From the government-controlled systems of the Cold War to today’s move towards cloud computing, user-driven content, and the new global commons, this book reveals the trends that are shaping the businesses, politics, and media of the digital future.

Book Description
With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and sharing-control mechanisms used to protect against unauthorized data access and secure dissemination of sensitive information. Image data protection and image-based authentication techniques offer efficient solutions for controlling how private data and images are made available only to select people. Essential to the design of systems used to manage images that contain sensitive data—such as medical records, financial transactions, and electronic voting systems—the methods presented in this book are useful to counter traditional encryption techniques, which do not scale well and are less efficient when applied directly to image files. An exploration of the most prominent topics in digital imaging security, this book discusses: Potential for sharing multiple secrets Visual cryptography schemes—based either on the probabilistic reconstruction of the secret image, or on different logical operations for combining shared images Inclusion of pictures in the distributed shares Contrast enhancement techniques Color-image visual cryptography Cheating prevention Alignment problems for image shares Steganography and authentication In the continually evolving world of secure image sharing, a growing number of people are becoming involved as new applications and business models are being developed all the time. This contributed volume gives academicians, researchers, and professionals the insight of well-known experts on key concepts, issues, trends, and technologies in this emerging field.

Book Description
From Roentgen to Rembrandt, Hounsfield to Hollywood and Vesalius to videogames, Imagining Imaging explores the deeply entwined relationship between art (and visual-based culture) and radiology / medical imaging. Including artworks from numerous historical eras representing varied geographic locations and visual traditions, alongside a diverse range of contemporary artists, Dr Jackson argues that the foundations of medical image construction and interpretation were laid down in artistic innovations dating back hundreds and thousands of years. Since the discovery of X-rays, artists and moviemakers have, in turn, drawn rich inspiration from radiographic imagery and concepts, but the process of cross-pollination between art and science has continued, with creative endeavour continuing to mould medical imaging examinations to this day. Blending a unique mix of art, science and medical history, together with aspects of visual neurophysiology and psychology, Imagining Imaging is essential reading for radiologists, radiographers and artists alike. Peppered with familiar TV and film references, personal insights into the business of image interpretation, and delivered in an accessible and humorous style, the book will also appeal to anyone who enjoys looking at pictures. Key features: Engaging synthesis of art and medical history, combined with anecdotes and experiences from a working clinical radiologist Diverse range of visual reference points including astronomy, botany and cartography, alongside comprehensive discussion of medical imaging modalities including plain radiography, ultrasound, CT and MRI 200 full colour illustrations

Book Description
This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.
