Böcker av David E. Alexander

"Scientifically accurate, up-to-date, and highly accessible, Nature's Flyers will interest not only amateur and professional ornithologists, ecologists, evolutionary biologists, physiologists, and engineers, but also anyone who is curious about the effects of flight on the evolution and diversity of the natural world." -- Biology Digest"Alexander achieves the difficult feat of explaining intrinsically complex phenomena without using mathematical or entomological jargon. As a result, the book is clear, beautifully written, and suitable for people at all levels." -- Physics Today

The world is becoming more hazardous as natural and social processes combine to create complex situations of increased vulnerability and risk. There is increasing recognition that this trend is creating exigencies that must be dealt with. The common approach is to delegate the task of preparing an emergency plan to someone. Often that person is expected to get on with job but rarely is the means and instruction of how to write such a plan provided to them. There are a host of instances in which the letter of the law, not the spirit, is honoured by providing a token plan of little validity.David Alexander provides, in this book, the assistance needed to write an emergency plan. It is a practical how to manual and guide aimed at managers in business, civil protection officers, civil security officials, civil defence commanders, neighbourhood leaders and disaster managers who have been tasked with writing, reviewing or preparing emergency plans for all kinds of emergency, disaster or catastrophe. He takes the reader through the process of writing an emergency plan, step by step, starting with the rationale and context, before moving on through the stages of writing and activating a basic, generic emergency plan and concludes with information on specific kinds of plan, for example, for hospitals and cultural heritage sites.This practical guide also provides a core for postgraduate training in emergency management and has been written in such a way that it is not tied to the legal constraints of any particular jurisdiction.

On the Wing is the first book to take a comprehensive look at the evolution of flight in all four groups of powered flyers: insects, pterosaurs, birds and bats. David Alexander describes and evaluates both traditional and modern wing-origin theories in light of new fossil and genetic evidence.

David Alexander provides a concise yet comprehensive and systematic primer on how to prepare for a disaster. The book introduces the methods, procedures, protocols and strategies of emergency planning, with an emphasis on situations within industrialized countries. It is designed to be a reference source and manual from which emergency mangers can extract ideas, suggestions and pro-forma methodologies to help them design and implement emergency plans.
