Hal Wallis (1898-1986) might not be as well known as David O. Selznick or Samuel Goldwyn, but the films he produced—Casablanca, Jezebel, Now, Voyager, The Life of Emile Zola, Becket, True Grit, and many other classics (as well as scores of Elvis movies)—have certainly endured. As producer of numerous films, Wallis made an indelible mark on the course of America's film industry, but his contributions are often overlooked. Bernard Dick offers the first comprehensive assessment of the producer's incredible career. A former office boy and salesman, Wallis first engaged with the film business as the manager of a Los Angeles movie theater in 1922. He attracted the notice of the Warner brothers, who hired him as a publicity assistant. Within three months he was director of the department, and appointments to studio manager and production executive quickly followed. Wallis went on to oversee dozens of productions and formed his own production company in 1944. Dick draws on numerous sources such as Wallis's personal production files and exclusive interviews with many of his contemporaries to finally tell the full story of his illustrious career. Dick combines his knowledge of behind-the-scenes Hollywood with fascinating anecdotes to create a portrait of one of Hollywood's early power players.

The development and use of medical and dental materials are highly interdisciplinary endeavors which require expertise in chemistry, materials science, medicine and/or dentistry, mechanics and design engineering. The Symposium upon which this treatise is based was organized to bring members from these communities together to explore problems of mutual interest. The biomaterials which are used in medical or dental prostheses must not only exhibit structural stability and provide the desired function, but they must also perform over extended periods of time in the environment of the body. The latter is a very stringent requirement. The oral and other physiological environments are designed by nature to break down many organic substances. Also of importance is the requirement that materials used in the prosthesis not have a deleterious effect on body tissues. Most foreign (to the body) substances are somewhat toxic to human tissues; in fact, few factors are more limiting in the medical prosthesis field than the biocompatibility problem. Some of these problems and the attempts to solve them are discussed in this volume.

Dream Machines is a history of the ways in which machines have been imagined. It considers seven different kinds of speculative, projected or impossible machine: machines for teleportation, dream-production, sexual pleasure and medical treatment and cure, along with 'influencing machines', invisibility machines and perpetual motion machines.

Ecotoxiclogical risk from multiple stressors covers any situation where org- isms are exposed to a combination of environmental stressors. These include physical and chemical pollutants as well as other stressors such as parasites and environmental impact (e. g. , climate change or habitat loss). The combi- tion of stressors can result in increased risk to organisms (either additive or synergistic effects) or decreased effects (protective or antagonistic effects). The multiple stressor challenge is an international, multi-disciplinary problem requiring an international, multi-disciplinary approach. The c- rent approach to multiple stressors is to examine one stressor at a time and assume additivity. Little work has been done on combinations of stressors such that potential interactions can be determined. The problem is very complex. Multiple stressors pose a whole spectrum of challenges that range from basic science to regulation, policy and gove- ance. The challenges raise fundamental questions about our understanding of the basic biological response to stressors, as well as the implications of those uncertainties in environmental risk assessment and management. In addition to the great breadth, there is also great depth in the research ch- lenges, largely due to the complexity of the issues. From a basic science point of view, many of the mechanisms and processes under investigation are at the cutting edge of science — involving new paradigms such as genomic ins- bility and bystander effects.

This is an entirely new edition of the author′s 1984 study (originally published by South End Press) of radical media and movements. The first and second sections are original to this new edition. The first section explores social and cultural theory in order to argue that radical media should be a central part of our understanding of media in history. The second section weaves an historical and international tapestry of radical media to illustrate their centrality and diversity, from dance and graffiti to video and the internet and from satirical prints and street theatre to culture-jamming, subversive song, performance art and underground radio. The section also includes consideration of ultra-rightist media as a key contrast case. The book′s third section provides detailed case-studies of the anti-fascist media explosion of 1974-75 in Portugal, Italy′s long-running radical media, radio and access video in the USA, and illegal media in the dissolution of the former Soviet bloc dictatorships.

Arsenic in drinking water derived from groundwater is arguably the biggest environmental chemical human health risk known at the present time, with well over 100,000,000 people around the world being exposed. Monitoring the hazard, assessing exposure and health risks and implementing effective remediation are therefore key tasks for organisations and individuals with responsibilities related to the supply of safe, clean drinking water. Best Practice Guide on the Control of Arsenic in Drinking Water, covering aspects of hazard distribution, exposure, health impacts, biomonitoring and remediation, including social and economic issues, is therefore a very timely contribution to disseminating useful knowledge in this area. The volume contains 10 short reviews of key aspects of this issue, supplemented by a further 14 case studies, each of which focusses on a particular area or technological or other practice, and written by leading experts in the field. Detailed selective reference lists provide pointers to more detailed guidance on relevant practice. The volume includes coverage of (i) arsenic hazard in groundwater and exposure routes to humans, including case studies in USA, SE Asia and UK; (ii) health impacts arising from exposure to arsenic in drinking water and biomonitoring approaches; (iii) developments in the nature of regulation of arsenic in drinking water; (iv) sampling and monitoring of arsenic, including novel methodologies; (v) approaches to remediation, particularly in the context of water safety planning, and including case studies from the USA, Italy, Poland and Bangladesh; and (vi) socio-economic aspects of remediation, including non-market valuation methods and local community engagement.
