Einstein's General Theory of Relativity leads to two remarkable predictions: first, that the ultimate destiny of many massive stars is to undergo gravitational collapse and to disappear from view, leaving behind a 'black hole' in space; and secondly, that there will exist singularities in space-time itself. These singularities are places where space-time begins or ends, and the presently known laws of physics break down. They will occur inside black holes, and in the past are what might be construed as the beginning of the universe. To show how these predictions arise, the authors discuss the General Theory of Relativity in the large. Starting with a precise formulation of the theory and an account of the necessary background of differential geometry, the significance of space-time curvature is discussed and the global properties of a number of exact solutions of Einstein's field equations are examined. The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions. A discussion of the Cauchy problem for General Relativity is also included in this 1973 book.

Durante casi un cuarto de siglo, los paises de la Trilateral han compartido un interes tripartito en la seguridad militar, el desarrollo economico y la democracia politica. Han coordinado sus esfuerzos para procurarse una defensa comun. Han colaborado en tareas de reconstruccion economica, de desarrollo industrial y de promocion del comercio, de inversion y bienestar en un marco comun de instituciones economicas internacionales. Han llevado las comodidades -y las ansiasde la clase media a una creciente mayoria de sus pueblos. De algun modo, tambien han desarrollado y consolidado paralelamente, cada uno a su manera, sus propias formas particulares de politica democratica, incluyendo el sufragio universal, las elecciones periodicas, la competencia entre partidos y la libertad de expresion y de reunion. Tras veinticinco anos, no es de extranar que los supuestos anteriores y las politicas relativas a la seguridad militar necesiten ser revisados y modificados a la luz de las nuevas circunstancias. Tampoco debe sorprendernos que las politicas e instituciones del sistema economico de la posguerra, basadas en la preeminencia del dolar, requieran de una reforma drastica. Los gobiernos, despues de todo, han existido tradicionalmente para tratar los problemas economicos y de seguridad y, de forma individual y colectiva, para adaptar sus politicas en estas areas a entornos cambiantes.

The first edition of this book is recognised as one of the definitive sources on the subject of Computational Geometry. In fact, O'Rourke has a long history in the field, has published many papers on the subject and is responsible for the computer graphics algorithms newsgroup which is where all computer geometers meet to discuss their ideas and problems. Typical problems discussed include how a polygon can be represented, how to calculate its area, how to detect if two polygons intersect and how to calculate the convex hull of a polygon. This leads onto more complex issues such as motion planning and seeing if a robot is able navigate from point x to point y without bumping into objects. The algorithms for these (and other) problems are discussed and many are implemented. In addition, many of the ideas are also discussed from the point of view of three and more dimensions. The only disappointment is that many problems are posed as questions at the end of the chapters and, as far as I could see, you cannot get the answers in the forms of a lecturer's supplement. This is fine in academia but not a lot of use for the commercial world. Due to the range of problems that incorporate computational geometry this book cannot be expected to answer every problem you might have. You will undoubtedly need access to other textbooks but I have been using the first edition of this book for many years and the second edition is a welcome addition to my bookshelf. If I was only allowed one computational geometry book then it would undoubtedly be this one.

Handbook of Physiology. Section 12. Exercise: Regulation and Integration of Multiple Systems Loring B. Rowell and John T. Shepherd (Editors) This section of the Handbook of Physiology, as well as the previous sections, is state-of-the-art in terms of one volume describing a specific aspect of physiology. Here the topic is the control of body function during exercise. The book is organized in three sections: control of the cardiorespiratory system, metabolic control, and motor control during exercise. The objectives of the book are to outline the current knowledge, describe areas where more information is needed, and suggest solutions for gaining more knowledge in each area. Drs. Rowell and Shepherd have accomplished these objectives. Approximately one third of the book is concerned with each of the major topics, and each of them is divided into eight or nine chapters. The chapters are narrow enough in their scope to provide a great deal of new information about specific topics, but broad enough to be of interest to most people concerned with those areas. In the subject areas with which I was familiar, most concepts were review in nature, but there was still enough new material to make the chapters worthwhile. When reading chapters with which I was less familiar, I was sometimes overwhelmed with information, but still learned a great deal. Therefore, it appears that most chapters were written or edited on a similar level. The authors have been careful to include the latest information and still provide some historical background. Along with the presentation of the information in the chapters, the extensive references(average over 300 per chapter) make this book valuable to students and researchers alike. The book covers control of the various systems extensively, but does not deal with many topics common to exercise physiology such as altitude, heat and cold, and nutrition and ergogenic aids. This is not a shortcoming since it was not a purpose of the book. Some of these topics are covered in other sections of the Handbook, while others can be found in other reviews. For that reason, this book is probably not appropriate for a person generally interested in exercise physiology but without a strong desire to learn about the topics specifically covered. With that caveat, however, this is an excellent book for anyone seriously interested in any of the areas covered. It would make a valuable addition to the libraries of doctoral and advanced masters level students, as well as researchers in the field.

Maps capture data expressing the economic complexity of countries from Albania to Zimbabwe, offering current economic measures and as well as a guide to achieving prosperity\n\nWhy do some countries grow and others do not? The authors of The Atlas of Economic Complexity offer readers an explanation based on "Economic Complexity," a measure of a society's productive knowledge. Prosperous societies are those that have the knowledge to make a larger variety of more complex products. The Atlas of Economic Complexity attempts to measure the amount of productive knowledge countries hold and how they can move to accumulate more of it by making more complex products.\n\nThrough the graphical representation of the "Product Space," the authors are able to identify each country's "adjacent possible," or potential new products, making it easier to find paths to economic diversification and growth. In addition, they argue that a country's economic complexity and its position in the product space are better predictors of economic growth than many other well-known development indicators, including measures of competitiveness, governance, finance, and schooling.\n\nUsing innovative visualizations, the book locates each country in the product space, provides complexity and growth potential rankings for 128 countries, and offers individual country pages with detailed information about a country's current capabilities and its diversification options. The maps and visualizations included in the Atlas can be used to find more viable paths to greater productive knowledge and prosperity.

From the Publisher: This book describes the extremely powerful technique of molecular dynamics simulation, which involves solving the classical many-body problem in contexts relevant to the study of matter at the atomic level. The method allows the prediction of the static and dynamic properties of substances directly from the underlying interactions between the molecules. Because there is no alternative approach capable of handling such a broad range of problems at the required level of detail, molecular dynamics methods have proved themselves indispensable in both pure and applied research.

Differences in the ways that men and women use language have long been of interest in the study of discourse. Despite extensive theorizing, actual empirical investigations have yet to converge on a coherent picture of gender differences in language. A significant reason is the lack of agreement over the best way to analyze language. In this research, gender differences in language use were examined using standardized categories to analyze a database of over 14,000 text files from 70 separate studies. Women used more words related to psychological and social processes. Men referred more to object properties and impersonal topics. Although these effects were largely consistent across different contexts, the pattern of variation suggests that gender differences are larger on tasks that place fewer constraints on language use.

Tied sales have a long history of scrutiny under the antitrust laws of the United States. The primary basis for the condemnation of this practice has been the court's belief in what has come to be known as the "leverage theory" of tying: that is, that tying provides a mechanism whereby a firm with monopoly power in one market can use the leverage provided by this power to foreclose sales in, and thereby monopolize, a aecond market, In recent years, however, the leverage theory has come under heavy attack. In this paper, I reconsider the leverage hypothesis.

Abstract Objective: To describe the obstacles encountered when attempting to answer doctors' questions with evidence. Design: Qualitative study. Setting: General practices in Iowa. Participants: 9 academic generalist doctors, 14 family doctors, and 2 medical librarians. Main outcome measure: A taxonomy of obstacles encountered while searching for evidence based answers to doctors' questions. Results: 59 obstacles were encountered and organised according to the five steps in asking and answering questions: recognise a gap in knowledge, formulate a question, search for relevant information, formulate an answer, and use the answer to direct patient care. Six obstacles were considered particularly salient by the investigators and practising doctors: the excessive time required to find information; difficulty modifying the original question, which was often vague and open to interpretation; difficulty selecting an optimal strategy to search for information; failure of a seemingly appropriate resource to cover the topic; uncertainty about how to know when all the relevant evidence has been found so that the search can stop; and inadequate synthesis of multiple bits of evidence into a clinically useful statement. Conclusions: Many obstacles are encountered when asking and answering questions about how to care for patients. Addressing these obstacles could lead to better patient care by improving clinically oriented information resources. What is already known on this topic Doctors are encouraged to search for evidence based answers to their questions about patient care but most go unanswered Studies have not defined the obstacles to answering questions in a systematic manner A comprehensive description of such obstacles has not been presented What this study adds Fifty nine obstacles were found while attempting to answer clinical questions with evidence; six were particularly salient The obstacles were comprehensively described and organised

This book looks at the origins, meaning, and uses of Conjure—the African American tradition of healing and harming that evolved from African, European, and American elements—from the slavery period to well into the twentieth century. Illuminating a world that is dimly understood by both scholars and the general public, the author describes Conjure and other related traditions, such as Hoodoo and Rootworking, in a detailed history which presents the voices and experiences of African Americans and shows how magic has informed their culture. Focusing on the relationship between Conjure and Christianity, she shows how these seemingly contradictory traditions have worked together in a complex and complementary fashion to provide spiritual empowerment for African Americans, both slave and free, living in white America. As she explores the role of Conjure for African Americans and looks at the transformations of Conjure over time, the author also rewrites the dichotomy between magic and religion. With its analysis of an often misunderstood tradition, the book helps to explain the myriad dimensions of human spirituality.

Caribbean migration to Britain brought many new things - new musics, new foods, new styles. It brought new ways of thinking too. This lively, innovative book explores the intellectual ideas which the West Indians brought with them to Britain. It shows that for more than a century West Indians living in Britain developed a dazzling intellectual critique of the codes of Imperial Britain. This is the first comprehensive discussion of the major Caribbean thinkers who came to live in twentieth-century Britain. Chapters discuss the influence of, amongst others, C. L. R. James, Una Marson, George Lamming, Jean Rhys, Claude McKay and V. S. Naipaul. The contributors to this fascinating volume draw from many different disciplines to bring alive the thought and personalities of the figures they discuss, providing a dramatic picture of intellectual developments in Britain from which we can still learn much. A lucid introduction argues that the recovery of this Caribbean past, on the home-territory of Britain itself, reveals much about the prospects of multiracial Britain. Written in an accessible manner, undergraduates and general readers interested in relations between the Caribbean and Britain, imperial history, literature, cultural and black studies will all find much of interest in this collection.\nTabel of contents:\nIntroduction: Crossing the seas Bill Schwarz\n1 What is a West Indian?

Abstract “Fat People Don't Go to Heaven!” screamed a headline in the tabloid Globe in November 2000. The story recounted the success of the Weigh Down Workshop, the nation's largest Christian diet corporation and the subject of extensive press coverage from Larry King Live to the New Yorker. In the United States today, hundreds of thousands of people are making diet a religious duty by enrolling in Christian diet programs and reading Christian diet literature such as What Would Jesus Eat? and Fit for God. Far ranging in its implications, and full of stories of real people, this book launches an investigation into Christian fitness and diet culture. Looking closely at both the religious roots of this movement and its present-day incarnations, the author analyzes Christianity's intricate role in America's obsession with the body, diet, and fitness. As she traces the underpinning of modern-day beauty and slimness ideals—as well as the bigotry against people who are overweight—she links seemingly disparate groups in American history including seventeenth-century New England Puritans, Progressive Era New Thought adherents, and late-twentieth-century evangelical diet preachers.

In 1971 Jurgen Habermas delivered the Gauss Lectures at Princeton University. These pivotal lectures, entitled Reflections on the Linguistic Foundation of Sociology, anticipate The Theory of Communicative Action and offer an excellent introduction to it. They show why Habermas considers the linguistic turn in social philosophy to be necessary and contain the first formulation of formal pragmatics, including an important discussion of truth.In these lectures and two additional essays, Habermas outlines an intersubjective approach to social theory that takes the concepts of meaning and communication to be central. In doing so, he situates his project relative to other influential accounts of how meaning is constituted, in particular those of Edmund Husserl, Wilfrid Sellars, and Ludwig Wittgenstein. He examines the nature of social interaction and its connection to communication, developing a linguistic conception of convention and intentionality. He also offers an account of social and individual pathologies using the concept of systematically distorted communication. Taken together, these analyses contribute significantly to current debates in the philosophy of action and language.
