Ron Comer's Abnormal Psychology continues to captivate students with its integrated coverage of theory, diagnosis, and treatment, its inclusive wide-ranging cross-cultural perspective, and its compassionate emphasis on the real impact of mental illness on the lives of patients and their families. Long acclaimed for being well attuned to the evolution of the field and changes in the classroom, Comer's bestselling text returns in a timely new edition, fully updated in anticipation of the DSM-5, and enhanced by powerful new media tools.

Knowledge representation is at the very core of a radical idea for understanding intelligence. Instead of trying to understand or build brains from the bottom up, its goal is to understand and build intelligent behavior from the top down, putting the focus on what an agent needs to know in order to behave intelligently, how this knowledge can be represented symbolically, and how automated reasoning procedures can make this knowledge available as needed. This landmark text takes the central concepts of knowledge representation developed over the last 50 years and illustrates them in a lucid and compelling way. Each of the various styles of representation is presented in a simple and intuitive form, and the basics of reasoning with that representation are explained in detail. This approach gives readers a solid foundation for understanding the more advanced work found in the research literature. The presentation is clear enough to be accessible to a broad audience, including researchers and practitioners in database management, information retrieval, and object-oriented systems as well as artificial intelligence. This book provides the foundation in knowledge representation and reasoning that every AI practitioner needs. - Authors are well-recognized experts in the field who have applied the techniques to real-world problems - Presents the core ideas of KR&R in a simple straight forward approach, independent of the quirks of research systems - Offers the first true synthesis of the field in over a decade

Attachment to host cells or tissues is often the first step in the establishment of bacterial infections. A complex array of recognition, attachment, and virulence factors is involved in this process, which recent research has greatly illuminated. This comprehensive and authoritative volume discusses the specific cell and tissue-specific affinities of pathogenic microorganisms, including bioinorganic surfaces such as teeth, and is an essential reference for researchers and students of host-pathogen interactions.

This book describes an exciting, but unfinished scientific adventure story. It tells of the epic struggle by scientists to wrest the secrets from nature of how to control the force of electromagnetism and how to control aerodynamic forces. Control of the force of gravity has yet to be achieved. Analogies suggest where a breakthrough might be made. Greenglow & the search for gravity control follows the attempts mankind has made over the years to understand gravity as well as looking at more recent experiments to control it. The book is written by an engineer, who worked in the aerospace industry, and who persuaded BAE Systems to sponsor Project Greenglow, a small research programme aimed at investigating some ideas for controlling gravity. Based on analogies in nature, the book provides a road map for scientists, engineers and the general public who want to know more about gravity and our search to control it. Discovering nature’s secrets is an exciting, but unfinished story – there is much we still don’t know. The book describes the quest by scientists to gain control of gravity and electromagnetism, the two long-range forces of nature. Faraday discovered the secret of electromagnetic control. Newton began the search for gravity control, later continued by Einstein, but it eluded them. One day the secret will be discovered either by careful experimentation or, as is often the case, by stumbling across it by chance. In the future it is expected that gravity control will underpin a new method of propulsion and this book concludes with a look at some possible forms. Greenglow is a fascinating read for any aerospace engineers, physicists, experimental research scientists, science journalists, science historians, futurologists, UFO enthusiasts, Star Trekkies and general public interested in the breakthrough in understanding of how to control gravity.

As a result of the industrial revolution, man's technological achievements have been truly great, increasing the quality of life to almost unimagined proportions; but all this progress has not been accomplished without equally un imagined health risks. Sufficiently diagnostic short-term assay procedures have been developed in recent years for us to determine that there are mutagenic agents among thou sands of chemicals to which the human population is exposed today. These chemicals were not significantly present prior to the indus trial revolution. As of today, there are no procedures available which have been adequately demonstrated to assess individual sus ceptibility to genotoxic exposures, and as a result we have had to rely on extrapolating toxicological data from animal model systems. The question is can we afford to allow such an increased environ mental selection pressure via mutagenic exposures to occur without expecting adverse long-term effects on our health. It is apparent from this line of reasoning that what is lacking and immediately needed are test procedures that can be applied to humans to assess genotoxic exposure as well as individual susceptibility to it. There have already been two conferences which have focused at tention on this research area. "Guidelines for studies of human populations exposed to mutagenic and reproductive hazards" (A. D. Bloom, ed., March of Dimes Birth Defects Foundation, White Plains, New York, 1981) and "Indicators of genotoxic exposure in humans" (Banbury Report 13, B. A. Bridges, B. E. Butterworth, and I. B.

How we can create artificial intelligence with broad, robust common sense rather than narrow, specialized expertise. It’s sometime in the not-so-distant future, and you send your fully autonomous self-driving car to the store to pick up your grocery order. The car is endowed with as much capability as an artificial intelligence agent can have, programmed to drive better than you do. But when the car encounters a traffic light stuck on red, it just sits there—indefinitely. Its obstacle-avoidance, lane-following, and route-calculation capacities are all irrelevant; it fails to act because it lacks the common sense of a human driver, who would quickly figure out what’s happening and find a workaround. In Machines like Us, Ron Brachman and Hector Levesque—both leading experts in AI—consider what it would take to create machines with common sense rather than just the specialized expertise of today’s AI systems. Using the stuck traffic light and other relatable examples, Brachman and Levesque offer an accessible account of how common sense might be built into a machine. They analyze common sense in humans, explain how AI over the years has focused mainly on expertise, and suggest ways to endow an AI system with both common sense and effective reasoning. Finally, they consider the critical issue of how we can trust an autonomous machine to make decisions, identifying two fundamental requirements for trustworthy autonomous AI systems: having reasons for doing what they do, and being able to accept advice. Both in the end are dependent on having common sense.

The America of the modern administrative state is not the America of the original Constitution. This transformation comes not only from the ordinary course of historical change and development, but also from a radical, new philosophy of government that was imported into the American political tradition by the Progressives of the late nineteenth century. The new thinking about the principles of government―and open hostility to the American Constitution―led to a host of concrete changes in American political institutions. Our government today reflects these original Progressive innovations, even if they are often unrecognized as such because they have become ingrained in American political culture. This book shows the nature of these changes, both in principles and in the nuts and bolts of governing. It also shows how progressivism was often at the root of critical developments subsequent to the Progressive Era in more recent American political history―how it was different than the New Deal, the liberalism of the 1960s, and today’s liberalism, but also how these subsequent developments could not have transpired without the ground laid by the original Progressives.
