In recent years, the impact of new experimental techniques (e.g., nuclear physics methods, availability of high-intensity light sources) as well as an increasing demand for atomic collision data in other fields of physics (e.g., plasma physics, astrophysics, laser physics, surface physics, etc.) have stimulated a renewed, strong interest in atomic collision research. Due to the explosive development of the various fields, scientists often even have dif ficulty in keeping up with their own area of research; as a result, the overlap between different fields tends to remain rather limited. Instead of having access to the full knowledge accumulated in other fields, one uses only the small fraction which at the moment seems to be of immediate importance to one's own area of interest. Clearly, many fruitful and stimulating ideas are lost in this way, causing progress to be made much more slowly than it could be. Atomic col lision physics is no exception to this rule. Although it is of basic interest to many other areas, it is mostly regarded merely as a (nonetheless important) tool by which to gain additional information.

A broad class of accelerators rests on the induction principle whereby the accelerating electrical fields are generated by time-varying magnetic fluxes. Particularly suitable for the transport of bright and high-intensity beams of electrons, protons or heavy ions in any geometry (linear or circular) the research and development of induction accelerators is a thriving subfield of accelerator physics. This text is the first comprehensive account of both the fundamentals and the state of the art about the modern conceptual design and implementation of such devices. Accordingly, the first part of the book is devoted to the essential features of and key technologies used for induction accelerators at a level suitable for postgraduate students and newcomers to the field. Subsequent chapters deal with more specialized and advanced topics.

The Proceedings of the Advanced study Institute on Fundamental Processes in Atomic Collision Physics (Santa Flavia, Italy, September 10-21, 1984) are dedicated to the memory of Sir Harrie r-1assey, whose scientific achievements and life are reviewed herein by Sir David Bates. At the first School on the above topic (Maratea, September 1983, Volume 103 in this series), Harrie Massey presented the introductory lectures, summarized the entire lecture program, and presented an outlook on future developments in atomic collision physics. In an after-dinner speech, Massey recalled personal reminiscences and historical events with regard to atomic collision physics, to which he had contributed by initiating pioneering work and by stimulating and surveying this branch of physics over a period of almost six decades. Participants in the Maratea School will always remember Harrie Massey as a charming and wonderful person who was most pleased to discuss with everyone--students, postdoctorals, and senior scientists--any topic in atomic collision physics. Harrie Massey was a member of the Scientific Advisory Committee of the 1984 Santa Flavia School. Before his death he expressed his interest in attending this second School devoted to the presentation of recent developments and highlights in atomic collision physics. It is the desire of all authors to honor Harrie Massey with their contributions in these Proceedings.

Geographical Information Systems (GIS) have developed rapidly in recent years and now provide powerful tools for the capture, manipulation, integration, interrogation, modelling, analysis and visualisation of data - tools that are already used for policy support in a wide range of areas at almost all geographic and administrative levels. This holds especially for emergency preparedness and health risk reduction, which are all essentially spatial problems. To date, however, many initiatives have remained disconnected and uncoordinated, leading to less powerful, less compatible and less widely implemented systems than might otherwise have been the case.
The important matters discussed here include the probabilistic nature of most environmental hazards and the semi-random factors that influence interactions between these and human exposures; the effects of temporal and spatial scales on hazard assessment and imputed risk; the effects of measurement error in risk estimation and the stratification of risks and their impacts according to socioeconomic characteristics; and the quantification of socioeconomic differences in vulnerability and susceptibility to environmental hazards.
GIS are powerful analytical tools in their own right, but what is needed is much more effective communication between the many disciplines, professions and stakeholders concerned - something which this book helps to achieve.

Accurate assessment of environmental hazards and related risks is a primary prerequisite for effective environmental health protection, at both the individual and collective level. National and regional policies on environmental health need to be guided by knowledge about the risks to the populations involved; as the Environmental Action Plan for Europe notes, 'priority setting requires the comparative assessment of risks to health of different environmental factors against the cost of controlling them.' In recent years this has assumed particular importance, for with the encouragement of the World Health Organisation (WHO), all countries in Europe are committed to producing National Environmental Health Action Plans (NEHAPs), which will define priorities and targets for environmental health and the actions needed to achieve them. Reliable information on risks is clearly fundamantal to this process. Individual risk assessment is no less important in this context. Much of the responsibility and capacity to improve public health lies ultimately in the choices (e.g. about diet, smoking, alcohol consumption, sexual activities, sporting activities, travel mode, place of residence and occupation) which we make as individuals. If we are to improve and protect our own health, therefore, and in so doing play our personal role in achieving the targets set by these Plans, we need to be guided by a clear understanding of the risks involved.

"Murdoch, Briggs, and Nisbet provide the most insightful development of cohesive ecological theory to have appeared in decades. For those who would say ecology is not making progress, this is the book with which to refute such uninspired myopia. In this era of 'applied' and 'relevant ecology, ' a theory book might seem out of place. But we all need to read this book to remind ourselves how hard it is to really understand nature, and to appreciate the discipline of thinking required when deciphering the consequences of those environmental hazards from which we recoil."--Peter Kareiva, Lead Scientist, The Nature Conservancy

"This is a very important, well-written, and well-organized book. Its major contribution is in showing that real consumer-resource dynamics can in fact be understood using a unified theoretical framework. It will appeal to population ecologists but also to applied mathematicians, and will serve as an entree into theoretical ecology for those with less of a theoretical bent."--Alan Hastings, University of California, Davis

""Consumer-Resource Dynamics" is an important book that fills a significant void in the field of theoretical ecology. It brings together the seemingly disparate components of consumer-resource theory under a unifying framework, successfully tackles the challenge of developing models that are both general and testable, and makes complicated mathematical theory accessible to the more empirical minded ecologist. Unlike most books in the field, it presents new theory and new insights, and suggests new empirical directions to pursue. Very well written, it will find a wide audience, from theorists to empiricists, from students to professors, and frombasic scientists to applied researchers. It will provide food for thought even to those who are experts in the field."--Priyanga Amarasekare, University of Chicago
