It is a branch of linguistics that looks less at the shape or sound of words--morphology or phonology--and more at how our words and sentences are influenced by the society around us--for instance, how the accent or the dialect we use has been shaped by where we come from or which social class we belong to. In this Very Short Introduction, John Edwards offers the most up-to-date brief overview available of sociolinguistics, with side trips into the sociology of language and psycholinguistics. He considers such topics as the different social evaluations of languages and dialects, the loaded significance of names, and the importance of politically-driven language planning and policy. The relationship between language and gender, sexist language, the language of poverty, and the intertwining of language and religion are also dealt with here. Edwards stresses that, while linguists see all dialects as equally valid, in the wider world powerful attitudes have always placed language varieties in social hierarchies. The author also looks at language more broadly, examining the ways in which languages rise or fall, the attempts to revive flagging or endangered varieties, the reasons why some languages came to dominate others, and the special dynamics that affect contact between "big" and "small" languages. In both its role as our most powerful tool of communication and as the most immediate symbolic marker of human affiliation, language is pre-eminently a social phenomenon. This compact volume offers an invaluable introduction to this vital aspect of language.

    An impassioned critique of K 12 mathematics education, it outlined how we shortchange students by introducing them to math the wrong way. Here Lockhart offers the positive side of the math education story by showing us how math should be done. "Measurement "offers a permanent solution to math phobia by introducing us to mathematics as an artful way of thinking and living.In conversational prose that conveys his passion for the subject, Lockhart makes mathematics accessible without oversimplifying. He makes no more attempt to hide the challenge of mathematics than he does to shield us from its beautiful intensity. Favoring plain English and pictures over jargon and formulas, he succeeds in making complex ideas about the mathematics of shape and motion intuitive and graspable. His elegant discussion of mathematical reasoning and themes in classical geometry offers proof of his conviction that mathematics illuminates art as much as science.Lockhart leads us into a universe where beautiful designs and patterns float through our minds and do surprising, miraculous things. As we turn our thoughts to symmetry, circles, cylinders, and cones, we begin to see that almost anyone can do the math in a way that brings emotional and aesthetic rewards. "Measurement" is an invitation to summon curiosity, courage, and creativity in order to experience firsthand the playful excitement of mathematical work."

    It discusses new results, along with applications of probability theory to a variety of problems. The book contains many exercises and is suitable for use as a textbook on graduate-level courses involving data analysis. Aimed at readers already familiar with applied mathematics at an advanced undergraduate level or higher, it is of interest to scientists concerned with inference from incomplete information.

    Supreme Court and its justices as a correspondent for the New York Times. In this Very Short Introduction, she draws on her deep knowledge of the court's history and of its written and unwritten rules to show readers how the Supreme Court really works.Greenhouse offers a fascinating institutional biography of a place and its people--men and women who exercise great power but whose names and faces are unrecognized by many Americans and whose work often appears cloaked in mystery. How do cases get to the Supreme Court? How do the justices go about deciding them? What special role does the chief justice play? What do the law clerks do? How does the court relate to the other branches of government? Greenhouse answers these questions by depicting the justices as they confront deep constitutional issues or wrestle with the meaning of confusing federal statutes. Throughout, the author examines many individual Supreme Court cases to illustrate points under discussion, ranging from Marbury v. Madison, the seminal case which established judicial review, to the recent District of Columbia v. Heller (2008), which struck down the District of Columbia's gun-control statute and which was, surprisingly, the first time in its history that the Court issued an authoritative interpretation of the Second Amendment. To add perspective, Greenhouse also compares the Court to foreign courts, revealing interesting differences. For instance, no other country in the world has chosen to bestow life tenure on its judges.A superb overview packed with telling details, this volume offers a matchless introduction to one of the pillars of American government.

    These, along with the introduction of the oral contraceptive, have altered all of our lives. There has also been an increase in the recreational use and abuse of drugs in the Western world. This Very Short Introduction gives a non-technical account of how drugs act on the body and how therapeutic drugs are developed and tested, then goes on to review both legal (prescription, alcohol, nicotine, and caffeine) and illegal drugs, and discuss current ideas about why some drugs are addictive, and whether drug laws need reform.

    They haunt us, we cherish them, and in our lives we collect more of them with each new experience. Without memory, you would not be able to maintain a relationship, drive your car, talk to your children, read a poem, watch television, or do much ofanything at all. Memory: A Very Short Introduction explores the fascinating intricacies of human memory. Is it one thing or many? Why does it seem to work well sometimes and not others? What happens when it goes wrong? Can it be improved or manipulated through techniques such as mnemonic rhymes orbrain implants? How does memory change as we age? And what about so-called recovered memories--can they be relied upon as a record of what actually happened in our personal past? This book brings together our most recent knowledge to address (in a scientifically rigorous but highly accessible way)these and many other important questions about how memory works, and why we can't live without it.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundredsof key topics, from philosophy to Freud, quantum theory to Islam.

    Newspaper column inches have been devoted to murderers with psychopathic features, and we also encounter psychopaths in films and books. Individuals with psychopathy are characterised in particular by lack of empathy and guilt, manipulation of other people and, in the case of criminal psychopathy, premeditated violent behaviour. They are dangerous and can incur immeasurable emotional, psychological, physical, and financial costs to their victims and their families.Despite the public fascination with psychopathy, there is often a very limited understanding of the condition, and several myths about psychopathy abound. For example, people commonly assume that all psychopaths are sadistic serial killers or that all violent and antisocial individuals are psychopaths. Yet, research shows that most psychopaths are not serial killers, and, equally, there are plenty of antisocial and violent offenders who are not psychopaths. This Very Short Introduction gives an overview of how we can identify individuals with or at risk of developing psychopathy, and how they differ from other people who display antisocial behavior. Essi Viding also explores the latest genetic, neuroscience, and psychology evidence in order to illuminate why psychopaths behave and develop the way they do, and considers whether it is possible to prevent or even treat psychopathy.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    The author illustrates important aspects of Africa's history with a range of fascinating historical examples, drawn from over 5 millennia across this vast continent. The multitude of topics that the reader will learn about in this succinct work include the unity and diversity of African cultures, slavery, religion, colonial conquest, the diaspora, and the importance of history in understanding contemporary Africa. The book examines questions such as: Who invented the idea of "Africa"? How is African history pieced together, given such a lack of documentary evidence? How did Africa interact with the world 1,000 years ago? Africa has been known as 'the cradle of mankind', and its recoverable history stretches back to the Pharaohs. But the idea of studying African history is itself new, and the authors show why it is still contested and controversial. This VSI, the first concise work of its kind, will prove essential reading for anyone interested in the African continent and the diversity of human history.

    He solidified his standing as the nation's foremost political forecaster with his near perfect prediction of the 2012 election. Silver is the founder and editor in chief of FiveThirtyEight.com. Drawing on his own groundbreaking work, Silver examines the world of prediction, investigating how we can distinguish a true signal from a universe of noisy data. Most predictions fail, often at great cost to society, because most of us have a poor understanding of probability and uncertainty. Both experts and laypeople mistake more confident predictions for more accurate ones. But overconfidence is often the reason for failure. If our appreciation of uncertainty improves, our predictions can get better too. This is the "prediction paradox": The more humility we have about our ability to make predictions, the more successful we can be in planning for the future.In keeping with his own aim to seek truth from data, Silver visits the most successful forecasters in a range of areas, from hurricanes to baseball, from the poker table to the stock market, from Capitol Hill to the NBA. He explains and evaluates how these forecasters think and what bonds they share. What lies behind their success? Are they good-or just lucky? What patterns have they unraveled? And are their forecasts really right? He explores unanticipated commonalities and exposes unexpected juxtapositions. And sometimes, it is not so much how good a prediction is in an absolute sense that matters but how good it is relative to the competition. In other cases, prediction is still a very rudimentary-and dangerous-science.Silver observes that the most accurate forecasters tend to have a superior command of probability, and they tend to be both humble and hardworking. They distinguish the predictable from the unpredictable, and they notice a thousand little details that lead them closer to the truth. Because of their appreciation of probability, they can distinguish the signal from the noise.

    But when people think about economics, they tend to place importance on the bigger picture - macroeconomics - including issues such as unemployment, inflation, and the competitiveness of nations.In this Very Short Introduction, Avinash Dixit argues that the microeconomy has a large impact on the economic world, arguably as much as the issues of macroeconomics.Dixit steers a clear path through the huge number of issues related to microeconomics, explaining what happens when things go well, as well as showing how they fail, why that happens, and what can be done about it. Using real-life examples from around the world, using a minimum of mathematics and including simple graphs, he provides insights into economics from psychology and sociology to explain economic behavior and rational choice.About the Series: Oxford's Very Short Introductions series offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, Literary Theory to History, and Archaeology to the Bible.

    As of 2004 an estimated 40 million people were living with the disease, and about 20 million had died. Despite rapid scientific advances there is still no cure and the drugs are expensive and toxic. In the developing world, especially in parts of Africa, life expectancy has plummeted to below 35 years, causing a serious decline in economic growth, a sharp increase in orphans, and the imminent collapse of health care systems. The news is not all bleak though. There have been unprecedented breakthroughs in understanding diseases and developing drugs. Because the disease is so closely linked to sexual activity and drug use, the need to understand and change behavior has caused us to reassess what it means to be human and how we should operate in the globalizing world. This Very Short Introduction tackles the science, the international and local politics, the fascinating demographics, and the devastating consequences of the disease, and suggests how we must respond.About the Series: Oxford's Very Short Introductions offers concise and original introductions to a wide range of subjects--from Islam to Sociology, Politics to Classics, and Literary Theory to History.

    Wade have on violent crime? Freakonomics will literally redefine the way we view the modern world.These may not sound like typical questions for an economist to ask. But Steven D. Levitt is not a typical economist. He is a much heralded scholar who studies the stuff and riddles of everyday life -- from cheating and crime to sports and child rearing -- and whose conclusions regularly turn the conventional wisdom on its head. He usually begins with a mountain of data and a simple, unasked question. Some of these questions concern life-and-death issues; others have an admittedly freakish quality. Thus the new field of study contained in this book: freakonomics.Through forceful storytelling and wry insight, Levitt and co-author Stephen J. Dubner show that economics is, at root, the study of incentives -- how people get what they want, or need, especially when other people want or need the same thing. In Freakonomics, they set out to explore the hidden side of ... well, everything. The inner workings of a crack gang. The truth about real-estate agents. The myths of campaign finance. The telltale marks of a cheating schoolteacher. The secrets of the Ku Klux Klan.What unites all these stories is a belief that the modern world, despite a surfeit of obfuscation, complication, and downright deceit, is not impenetrable, is not unknowable, and -- if the right questions are asked -- is even more intriguing than we think. All it takes is a new way of looking. Steven Levitt, through devilishly clever and clear-eyed thinking, shows how to see through all the clutter.Freakonomics establishes this unconventional premise: If morality represents how we would like the world to work, then economics represents how it actually does work. It is true that readers of this book will be armed with enough riddles and stories to last a thousand cocktail parties. But Freakonomics can provide more than that. It will literally redefine the way we view the modern world.(front flap)

    This fascinating Very Short Introduction discusses all the aspects of psychology that are relevant to the legal and criminal process as a whole. It includes explanations of criminal behavior and criminality, including the role of mental disorder in crime, and it reveals how forensic psychology contributes to helping investigate the crime and catching the perpetrators. David Canter also explains how psychologists provide guidance to all those involved in civil and criminal court proceedings, including both the police and the accused, and what expert testimony can be provided by a psychologist about the offender at the trial. Finally, Canter describes how forensic psychology is used, particularly in prisons, to help in the management, treatment and rehabilitation of offenders, once they have been convicted.

    The authors introduce the general reader to some of the most important basic findings, concepts, and procedures of evolutionary biology, as it has developed since the first publications of Darwin and Wallace on the subject, over 140 years ago. They show how evolution provides a unifying set of principles for the whole of biology and sheds light on the relation of human beings to the universe and each other.
