"Links" are among the most basic---and most unexamined---features of online life. Bringing together a prominent array of thinkers from industry and the academy, The Hyperlinked Society addresses a provocative series of questions about the ways in which hyperlinks organize behavior online. How do media producers' considerations of links change the way they approach their work, and how do these considerations in turn affect the ways that audiences consume news and entertainment? What role do economic and political considerations play in information producers' creation of links? How do links shape the size and scope of the public sphere in the digital age? Are hyperlinks "bridging" mechanisms that encourage people to see beyond their personal beliefs to a broader and more diverse world? Or do they simply reinforce existing bonds by encouraging people to ignore social and political perspectives that conflict with their existing interests and beliefs?

This pathbreaking collection of essays will be valuable to anyone interested in the now taken for granted connections that structure communication, commerce, and civic discourse in the world of digital media.

"This collection provides a broad and deep examination of the social, political, and economic implications of the evolving, web-based media environment. The Hyperlinked Society will be a very useful contribution to the scholarly debate about the role of the internet in modern society, and especially about the interaction between the internet and other media systems in modern society."

The shapes reflect the blogs, and the colors of the shapes reflect political orientation---red for conservative blogs, blue for liberal ones. The size of each blog reflects the number of blogs that link to it.

As the twentieth century draws to a close, it is time to look back on an epoch of widespread turmoil, including two world wars, the end of the colonial era in world history, and a large number of international crises and conflicts. This book is designed to shed light on the causes and consequences of military-security crises since the end of World War I, in every region, across diverse economic and political regimes, and cultures. The primary aim of this volume is to uncover patterns of crises, conflicts and wars and thereby to contribute to the advancement of international peace and world order.
The culmination of more than twenty years of research by Michael Brecher and Jonathan Wilkenfeld, the book analyzes crucial themes about crisis, conflict, and war and presents systematic knowledge about more than 400 crises, thirty-one protracted conflicts and almost 900 state participants. The authors explore many aspects of conflict, including the ethnic dimension, the effect of different kinds of political regimes--notably the question whether democracies are more peaceful than authoritarian regimes, and the role of violence in crisis management. They employ both case studies and aggregate data analysis in a Unified Model of Crisis to focus on two levels of analysis--hostile interactions among states, and the behavior of decision-makers who must cope with the challenge posed by a threat to values, time pressure, and the increased likelihood that military hostilities will engulf them.
This book will appeal to scholars in history, political science, sociology, and economics as well as policy makers interested in the causes and effects of crises in international relations. The rich data sets will serve researchers for years to come as they probe additional aspects of crisis, conflict and war in international relations.
