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.

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.

Having sold more than 40,000 copies of previous editions, this authoritative climbing guide has been completely revised, updated and redesigned for a whole new generation of mountaineers. The original edition of Scrambles in the Canadian Rockies, published by RMB in 1991, started a scrambling craze in the Canadian Rockies. No longer was reaching the top of those breathtaking peaks limited only to technical climbers; strong hikers with a sense of adventure found that they too could reach the top of many famous and stunning peaks. Armed with first-hand information, Alan Kane describes over 150 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. Most ascents are day trips from a major road; many utilize a hiking trail on approach and include some of the most-photographed Rockies postcard peaks. The scramble areas begin in Waterton Park near the US border and continue north through Crowsnest, Kananaskis, Canmore and into the contiguous mountain parks of Banff, Yoho, Kootenay and Jasper. An overview of facilities, accommodation and climate is provided for each area. Specific hazards from rock quality to wildlife encounters are mentioned, including advice on scrambling safely. Guidebooks can be dry reading, but Kane’s snippets of humour make the book entertaining as well as useful.
