    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.

    This Very Short Introduction discusses both the history and key debates of postcolonialism, and considers its importance as a means of changing the way we think about the world.Robert J. C. Young examines the key strategies that postcolonial thought has developed to engage with the impact of sometimes centuries of western political and cultural domination. Situating the discussion in a wide cultural and geographical context, he draws on examples such as the status of indigenous peoples, of those dispossessed from their land, Algerian rai music, and global social and ecological movements. In this new edition he also includes updated material on race, slavery, and postcolonial gender politics. Above all, Young argues that postcolonialism offers a political philosophy of activism that contests the current situation of global inequality, which in a new way continues the anti-colonial struggles of the past and enables us to decolonize our own lives in the present.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

    Bill Gates. George W. Bush. Osama bin Laden. Leaders and leadership are perennial topics of debate. What is leadership? How does one become a leader? Do we actually need leaders? In this Very Short Introduction, Keith Grint offers provocative answers to these questions, prompting readers to rethink their assumptions about what leadership is. Indeed, Grint argues that leadership is a very elusive quality, and that there are few definitive answers to be found, which explains why most books on leadership produce so much heat and so little light. But there are important questions to ask, questions which shed light on why leadership so resists definition. Grint looks at the way leadership has evolved from its earliest manifestations in ancient societies, highlights the early ideas about leadership found in Plato, Sun Tzu, Machiavelli and others, considers how social, economic, and political forces can undermine particular modes of leadership, and discusses the practice of management, its history, future, and influence on all aspects of society.

    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.

    Readers meet a people highly skilled in sculpture, astronomy, city planning, poetry, and philosophy, who were also profoundly committed tocosmic regeneration through the thrust of the ceremonial knife and through warfare. Dav�d Carrasco looks beyond Spanish accounts that have colored much of the Western narrative to let Aztec voices speak about their origin stories, the cosmic significance of their capital city, their methods of childrearing, and the contributions women made to daily life and the empire. Carrasco discusses the arrival of the Spaniards, contrasts Aztec mythical traditions about the origins of their city with actual urban life in Mesoamerica, and outlines the rise of the Aztec empire. He also explores Aztecreligion, which provided both justification for and alternatives to warfare, sacrifice, and imperialism, and he sheds light on Aztec poetry, philosophy, painting, and especially monumental sculpture and architecture. He concludes by looking at how the Aztecs have been portrayed in Western thought, art, film, and literature as well as in Latino culture and arts.

    Politicians of all stripes stress its importance, as do church leaders, captains of industry and every kind of campaigning group--from those supporting global causes, such as tackling world poverty, to others with a largely local focus, such as combating neighborhood crime. In this brilliant, compact introduction, Richard Bellamy offers an eye-opening look at an idea that is as important as it is rare--the prospect of influencing government policy according to reasonably fair rules and on a more or less equal basis with others. Bringing together the most recent scholarship, the book sheds light on how ideas of citizenship have changed through time from ancient Greece to the present, looks at concepts such as membership and belonging, and highlights the relation between citizenship, rights, and democracy. Bellamy also examines the challenges confronting the very possibility of citizenship today, the impact of globalization, the desirability of "global citizenship," the teaching of citizenship in schools, citizenship tests for immigrants, and the many different definitions and types of citizenship in modern society.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Atheism: A Very Short Introduction sets out to dispel the myths that surround atheism and show how a life without religious belief can be positive, meaningful, and moral. It also confronts the failure of officially atheist states in the Twentieth Century. The book presents an intellectual case for atheism that rests as much upon positive arguments for its truth as on negative arguments against religion.

    This book gives a succinct explanation of his metaphysical system, concentrating on the original aspects of his thought, which inspired many artists and thinkers including Nietzsche, Wagner, Freud, and Wittgenstein. Schopenhauer's central notion is that of the will--a blind, irrational force that he uses to interpret both the human mind and the whole of nature. Seeing human behavior as that of a natural organism governed by the will to life, Schopenhauer developed radical insights concerning the unconscious and sexuality which influenced both psychologists and philosophers

    It is truly a vital field, central to the health of society, but it is often poorly understood, largely due to misrepresentations in the media. In this Very Short Introduction, an internationally recognized authority on epidemiology, Dr. Rodolfo Saracci, provides a wealth of information on this key field, dispelling some of the myths surrounding the study of epidemiology, and explaining what epidemiology is and how vital it is to the discovery, control, and prevention of disease in world populations. Dr. Saracci provides a general explanation of the principles behind clinical trials, and explains the nature of basic statistics concerning disease. He also looks at the ethical and political issues related to obtaining and using information concerning patients, and trials involving placebos.

    But what exactly is populism? Should everyone who criticizes Wall Street or Washington be called a populist? What precisely is the difference between right-wing and left-wing populism? Does populism bring government closer to the people or is it a threat to democracy? Who are "the people" anyway and who can speak in their name? These questions have never been more pressing.In this groundbreaking volume, Jan-Werner MUller argues that at populism's core is a rejection of pluralism. Populists will always claim that they and they alone represent the people and their true interests. MUller also shows that, contrary to conventional wisdom, populists can govern on the basis of their claim to exclusive moral representation of the people: if populists have enough power, they will end up creating an authoritarian state that excludes all those not considered part of the proper "people." The book proposes a number of concrete strategies for how liberal democrats should best deal with populists and, in particular, how to counter their claims to speak exclusively for "the silent majority" or "the real people."Analytical, accessible, and provocative, What Is Populism? is grounded in history and draws on examples from Latin America, Europe, and the United States to define the characteristics of populism and the deeper causes of its electoral successes in our time.

    Dana Arnold also examines the many different ways of writing about art, and the changing boundaries of the subject of art history.Other topics covered include the canon of art history, the role of the gallery, "blockbuster" exhibitions, the emergence of social histories of art (such as feminist art history or queer art history), and the impact of photography. The development of art history using artifacts such as the altarpiece, the portrait, or pornography to explore social and cultural issues such as consumption, taste, religion, and politics is discussed. And the book also explains how the traditional emphasis on periods and styles originated in western art production and can obscure other approaches.

    Following on the success of his best-selling The Future of Freedom, Zakaria describes with equal prescience a world in which the United States will no longer dominate the global economy, orchestrate geopolitics, or overwhelm cultures. He sees the "rise of the rest"—the growth of countries like China, India, Brazil, Russia, and many others—as the great story of our time, and one that will reshape the world. The tallest buildings, biggest dams, largest-selling movies, and most advanced cell phones are all being built outside the United States. This economic growth is producing political confidence, national pride, and potentially international problems. How should the United States understand and thrive in this rapidly changing international climate? What does it mean to live in a truly global era? Zakaria answers these questions with his customary lucidity, insight, and imagination.

    How closely linked are migrants with terrorist organizations? What factors lie behind the dramatic increase in the number of woman migrating? This Very Short Introduction looks at the global phenomenon of human migration--both legal and illegal-revealing how migration actually presents opportunities that must be taken advantage of in light of the current economic climate. The author debunks myths such as the claim that migrants take jobs away from local workers, or that they take advantage of health care systems. He reveals why society as we now know it could not function without them.Using interviews with migrants from around the world, the author presents the human side of topics such as asylum and refugees, human trafficking, migrant smuggling, development, and the international labor force. His goal throughout is to allow readers to see beyond the negative spin usually given the subject by the media and politicians, and come to their own conclusions on the current international migration situation. It is a valuable reference for students of economics, politics, geography, or sociology, and for anyone interested in taking a deeper look at media coverage of immigration and its effects.
