The Deepening Divide: Inequality in the Information Society explains why the digital divide is still widening and, in advanced high-tech societies, deepening. Taken from an international perspective, the book offers full coverage of the literature and research and a theoretical framework from which to analyze and approach the issue. Where most books on the digital divide only describe and analyze the issue, Jan van Dijk presents 26 policy perspectives and instruments designed to close the divide itself.
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.
The refereed proceedings of the 7th European Conference on Symbolic and Quantitative Approaches to Reasoning with Uncertainty, ECSQARU 2003, held in Aalborg, Denmark in July 2003. The 47 revised full papers presented together with 2 invited survey articles were carefully reviewed and selected for inclusion in the book. The papers are organized in topical sections on foundations of uncertainty concepts, Bayesian networks, algorithms for uncertainty inference, learning, decision graphs, belief functions, fuzzy sets, possibility theory, default reasoning, belief revision and inconsistency handling, logics, and tools.
Since Charles Spearman published his seminal paper on factor analysis in 1904 and Karl Joresk ̈ og replaced the observed variables in an econometric structural equation model by latent factors in 1970, causal modelling by means of latent variables has become the standard in the social and behavioural sciences. Indeed, the central va- ables that social and behavioural theories deal with, can hardly ever be identi?ed as observed variables. Statistical modelling has to take account of measurement - rors and invalidities in the observed variables and so address the underlying latent variables. Moreover, during the past decades it has been widely agreed on that serious causal modelling should be based on longitudinal data. It is especially in the ?eld of longitudinal research and analysis, including panel research, that progress has been made in recent years. Many comprehensive panel data sets as, for example, on human development and voting behaviour have become available for analysis. The number of publications based on longitudinal data has increased immensely. Papers with causal claims based on cross-sectional data only experience rejection just for that reason.
This book discusses the new era of modern retinal laser therapy and its clinical applications. While the photocoagulation era universally presupposed the therapeutic necessity of laser-induced retinal damage, the modern retinal laser therapy is equally opposed to this idea. The evidence for this sea-change in the understanding of retinal laser is well presented within this book, and the conceptual and clinical consequences are discussed with particular emphasis on the emergence of retinal laser therapy as the first reasonable preventive and restorative intervention for the most important retinal disorders. Finally, the future of modern retinal laser therapy is highlighted with respect to coming technological advances, remaining challenges, and the place of retinal laser in the management of retinal disease. This book is an essential resource for all ophthalmic residents and clinicians seeking a clear and concise guide to modern retinal laser therapy in their everyday practice.

Increasing attention is being paid to the political uses of the new communication technologies. Digital Democracy offers an invaluable in-depth explanation of what issues of theory and application are most important to the emergence and development of computer-mediated communication systems for political purposes. The book provides a wide-ranging critical examination of the concept of virtual democracy as discussed in theory and as implemented in practice and policy that has been hitherto unavailable. It addresses how the Internet, World Wide Web and computer-mediated political communication are affecting democracy and focuses on the various theoretical and practical issues involved in digital democracy. Using international examples Digital Democracy attempts to connect theoretical analysis to considerations of practice and policy.
