Herbert Schiller, long one of America's leading critics of the communications industry, here offers a salvo in the battle over information. In Information Inequality he explains how privatization and the corporate economy directly affect our most highly prized democratic institutions: schools and libraries, media, and political culture. A master media-watcher, Schiller presents a crisp and far-reaching indictment of the "data deprivation" corporate interests are inflicting on the social fabric.

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.

Beneficial to scholars and students in the fields of media and communication, politics and technology, this book outlines the significant role of search engines in general and Google in particular in widening the digital divide between individuals, organisations and states. It uses innovative methods and research approaches to assess and illustrate the digital divide by comparing the popular search queries in Google and Yahoo in different countries as well as analysing the various biases in Google News and Google Earth. The different studies developed and presented in this book provide various indications of the increasing customisation and popularisation mechanisms employed by popular search engines, which together with "organising the world's information inevitably also intensify information inequalities and reinforce commercial and US-centric priorities and agendas. - Develops an extensive historical investigation of information, power and the digital divide - Provides new social and political perspectives to understand search engines in general and Google in particular - Suggests original methods to study and assess the digital divide as well as the extent of commercialisation and Americanisation worldwide

Who shapes our digital landscapes, and why are so many people excluded from them?

Concentration of Measure Inequalities in Information Theory, Communications, and Coding focuses on some of the key modern mathematical tools that are used for the derivation of concentration inequalities, on their links to information theory, and on their various applications to communications and coding.

TCC 2009, the 6th Theory of Cryptography Conference, was held in San Fr- cisco, CA, USA, March 15–17, 2009. TCC 2009 was sponsored by the Inter- tional Association for Cryptologic Research (IACR) and was organized in - operation with the Applied Crypto Group at Stanford University. The General Chair of the conference was Dan Boneh. The conference received 109 submissions, of which the Program Comm- tee selected 33 for presentation at the conference. These proceedings consist of revised versions of those 33 papers. The revisions were not reviewed, and the authors bear full responsibility for the contents of their papers. The conference program also included two invited talks: “The Di?erential Privacy Frontier,” given by Cynthia Dwork and “Some Recent Progress in Lattice-Based Crypt- raphy,” given by Chris Peikert. I thank the Steering Committee of TCC for entrusting me with the resp- sibility for the TCC 2009 program. I thank the authors of submitted papers for their contributions. The general impression of the Program Committee is that the submissions were of very high quality, and there were many more papers we wanted to accept than we could. The review process was therefore very - warding but the selection was very delicate and challenging. I am grateful for the dedication, thoroughness,and expertise ofthe ProgramCommittee. Obse- ing the way the members of the committee operated makes me as con?dent as possible of the outcome of our selection process.
