In our age of media revolutions, Patrick M. Garry offers guidelines for constitutionally redefining the press, and maintains that the First Amendment press clause must broaden the scope of its freedoms to include the communication activities of a much larger public.
Unroped scrambling over so-called easy terrain is one of the most potentially dangerous recreational activities. Every year, scramblers are injured or killed in preventable accidents. "A Hiker's Guide to Scrambling Safely" educates new scramblers in the inherent risks, required climbing skills and mountain knowledge required for safety in the mountains.
Video Scrambling and Descrambling for Satellite & Cable TV provides the "how and why" of encoding and decoding video signals. Most of the currently used methods are discussed, with the necessary technical background. Since digital scrambling methods will undoubtedly supplant analog methods, information on analog/digital conversion, phase-locked loops, digital techniques, and IC data sheets are included. In this new edition the authors incorporate the many developments in this field since 1986. They elaborate the basic information on scrambling given in the first edition, and discuss current scrambling systems such as Tri-mode, SSAVI, and Videocipher II. Looking back at the "gloom and doom" predictions made in the 80s, they discuss which have proven correct, which have yet to be realized, and which have been wrong. Their discussion of basic circuitry now includes some new IC devices, and the section on political, legal and consumer aspects of scrambling has been completely updated. New digitization techniques and construction data, decoder circuitry, audio scrambling techniques, manufacturers' data sheets, US Patents, and current developments such as digital audio are also covered in this updated version.

Scramblers and shift register generators (SRG) have been used for decades in the shaping of digital transmission signals and in generating pseudo-random binary sequences for transmission applications. In recent years more attention has been paid to this area than ever before due to the change of today's telecommunication environment. This publication presents the theory and applications of three scrambling techniques - Frame Synchronous Scrambling (FSS), Distributed Sample Scrambling (DSS) and Self Synchronous Scrambling (SSS) with an emphasis on their application in digital transmission. Based on the authors' research over the past ten years, this is the first book of its kind.
Annotation Armed with first-hand information, Alan Kane describes over 170 scrambles in a clear, concise format. This includes equipment needed, when to go, how to get there, where to park and what to expect as you work your way to the summit. Photos showing the ascent line complement descriptions that include historical trivia, origins of placenames and summit views. Routes range from off-trail hiking suitable for strong hikers to challenging routes at the low end of technical climbing where use of specific handholds is required on steep, airy terrain.

Once marginalized in the world economy, the past decade has seen Africa emerge as a major global supplier of crucial raw materials like oil, uranium and coltan. With its share of world trade and investment now rising and the availability of natural resources falling, the continent finds itself at the centre of a battle to gain access to and control of its valuable natural assets. China's role in Africa has loomed particularly large in recent years, but there is now a new scramble taking place involving a wider range of established and emerging economic powers from the EU and US to Japan, Brazil and Russia. This book explores the nature of resource and market competition in Africa and the strategies adopted by the different actors involved - be they world powers or small companies. Focusing on key commodities, the book examines the dynamics of the new scramble and the impact of current investment and competition on people, the environment, and political and economic development on the continent. New theories, particularly the idea of Chinese "flexigemony" are developed to explain how resources and markets are accessed. While resource access is often the primary motive for increased engagement, the continent also offers a growing market for low-priced goods from Asia and Asian-owned companies. Individual chapters explore old and new economic power interests in Africa; oil, minerals, timber, biofuels, food and fisheries; and the nature and impacts of Asian investment in manufacturing and other sectors. The New Scramble for Africa will be essential reading for students of African studies, international relations, and resource politics as well as anyone interested in current affairs.
The fortunes of the late nineteenth century’s imperial and industrial powers depended on a single raw material—rubber—with only one source: the Amazon basin. And so began the scramble for the Amazon—a decades-long conflict that found Britain, France, Belgium, and the United States fighting with and against the new nations of Peru, Bolivia, and Brazil for the forest’s riches. In the midst of this struggle, Euclides da Cunha, engineer, journalist, geographer, political theorist, and one of Brazil’s most celebrated writers, led a survey expedition to the farthest reaches of the river, among the world’s most valuable, dangerous, and little-known landscapes. The Scramble for the Amazon tells the story of da Cunha’s terrifying journey, the unfinished novel born from it, and the global strife that formed the backdrop for both. Haunted by his broken marriage, da Cunha trekked through a beautiful region thrown into chaos by guerrilla warfare, starving migrants, and native slavery. All the while, he worked on his masterpiece, a nationalist synthesis of geography, philosophy, biology, and journalism he named the Lost Paradise. Da Cunha intended his epic to unveil the Amazon’s explorers, spies, natives, and brutal geopolitics, but, as Susanna B. Hecht recounts, he never completed it—his wife’s lover shot him dead upon his return. At once the biography of an extraordinary writer, a masterly chronicle of the social, political, and environmental history of the Amazon, and a superb translation of the remaining pieces of da Cunha’s project, The Scramble for the Amazon is a work of thrilling intellectual ambition.
Countries in sub-Saharan Africa were once dismissed by Western experts as being too poor and chaotic to benefit from the antiretroviral drugs that transformed the AIDS epidemic in the United States and Europe. Today, however, the region is courted by some of the most prestigious research universities in the world as they search for "resource-poor" hospitals in which to base their international HIV research and global health programs. In Scrambling for Africa, Johanna Tayloe Crane reveals how, in the space of merely a decade, Africa went from being a continent largely excluded from advancements in HIV medicine to an area of central concern and knowledge production within the increasingly popular field of global health science. Drawing on research conducted in the U.S. and Uganda during the mid-2000s, Crane provides a fascinating ethnographic account of the transnational flow of knowledge, politics, and research money—as well as blood samples, viruses, and drugs. She takes readers to underfunded Ugandan HIV clinics as well as to laboratories and conference rooms in wealthy American cities like San Francisco and Seattle where American and Ugandan experts struggle to forge shared knowledge about the AIDS epidemic. The resulting uncomfortable mix of preventable suffering, humanitarian sentiment, and scientific ambition shows how global health research partnerships may paradoxically benefit from the very inequalities they aspire to redress. A work of outstanding interdisciplinary scholarship, Scrambling for Africa will be of interest to audiences in anthropology, science and technology studies, African studies, and the medical humanities.
