New laser technology has developed a new dye chemistry Development of the gallium-arsenic semiconductor laser (diode laser) that emits laser light at 780-830 nm has made possible development of new opto-electronic systems including laser optical recording systems, thermal writing display systems, laser printing systems, and so on. Medical applications of lasers in photodynamic therapy for the treatment of cancer were also developed. In such systems, the infrared absorbing dyes OR dyes) are currently used as effective photoreceivers for diode lasers, and will become the key materials in high...

This book owes its existence to an ideal, a burning frustration, and a trusted believer. The ideal was the sense that governed my feelings about systematic desensitization during my early introduction to its benefits. It is hard to put into words the initial doubts that pervaded me during my first attempt with desensitization with a seriously phobic client, as I re ligiously worked my way through the procedure: "Will this client really become relaxed? And then what-will the visualization actually occur? And then what-will the fear really vanish, just like that?" And oh, the feeling of...

The phenomenon of catalysis is found in many homogeneous and heterogeneous systems undergoing chemical change, where it effects the rates of approach to the equilibrium state in processes as diverse as those found in the stars, the earth's mantle, living organisms, and the various chemistries utilized by industry. The economies and the living standards of both developed and developing countries depend to varying degrees upon the efficacy of their chemical industries. Con- sequently, this century has seen a wide exploration and expansion of catalytic chemistry together with an intensive...

This book is written for a truly general medical audience. Clinicians, researchers, residents, and students will find Al cohol a direct treatment of the major drug problem in Amer ica. Along with the first volume in this series on marijuana, Alcohol is timely and relevant. The subject is presented with clarity in an effort to provide professionals and interested readers with a basic background in the field of alcohol studies. The emphasis is on what is known and can be coun ted on as fundamental knowledge on the various aspects of history, epidemiology, diagnosis, treatment, and prevention of...

This book is dedicated to all those who love children and their wonderful, often surprising, drawings. This means it addresses all those interested in their devel oping capacity to produce "iconic" signs: parents, teachers, child psychologists, artists, architects (since building drawings are treated here), and semioticians at large-to name but a few potential readers. Because of the broad audience, I tried to keep scientific jargon to a minimum. Whenever this was unavoidable, I tried to explain the terms in such a way that even beginners in psychology could understand my arguments. I...

Having spent more than thirty years in the laboratory studying human behavior under preformatted, controlled conditions, I found myself dissatisfied with my work. It is not that my work produced no new findings on human conduct, or that working almost exclusively with college students gave me little information on other groups of people, but that the study of human beings in the laboratory told me little about the people themselves. Having been born in Europe, socialized in the Middle East, and educated in the United States, I had entered the profession of psychology in order to better...

In the last few years the subject of optical cornmunications has moved rapidly from being a promising research area to a practical reality already being installed and carrying traffic in trunk networks in many countries. At the same time new applications for fibre technology are emerging and are placing new demands on the system components. In telecommunications there is a steady increase of interest in the use of fibres for undersea cables, in local area networks and wideband links, and a little further ahead the possibility of coherent communications systems. With an optical carrier...

Humankind's ever-expanding activities have caused environmental changes that reach beyond localities and regions to become global in scope. Disturbances to the atmosphere, oceans, and land produce changes in the living parts of the planet, while, at the same time, alterations in the biosphere modify the atmosphere, oceans, and land. Understanding this complex web of interactions poses unprecedented intellectual challenges. The atmospheric concentrations of natural trace gases-carbon dioxide (C0 ), methane (CH. ), nitrous oxide (N0), and lower-atmosphere ozone 2 2 (Os)-have increased since the...

This book is a venture in the worlds of modeling and of metamodeling. At this point, I will not reveal to readers what constitutes metamodeling. Suf fice it to say that the pitfalls and shortcomings of modeling can be cured only if we resort to a higher level of inquiry called metainquiry and metadesign. We reach this level by the process of abstraction. The book contains five chapters from my previous work, Applied General Systems Theory (Harper and Row, London and New York, First Edition 1974, Second Edition 1978). More than ten years after its publication, this material still appears...

The origins of this book probably go back to Gordon Allport's seminar in social psychology at Harvard during the late 1940s and to the invitation from Gardner Lindzey, some years later, to contribute a section on "Sympathy and Empathy" to the International Encyclopedia of the Social Sciences (1968). Since those early beginnings, the book has been "in the process of becoming. " During that time I have benefited greatly from the knowledge and assistance of many colleagues, especially the following, who read and commented upon portions of the manuscript: Raymond Gastil, the late Joseph Katz,...
