Still fewer understand the role played by political parties in the electoral process or the ironies within the system. Participation in elections in the United States is much lower than in the vast majority of mature democracies. Perhaps this is because of the lack of competition in a country where only two parties have a true chance of winning, despite the fact that a large number of citizens claim allegiance to neither and think badly of both. Or perhaps it is because in the U.S. campaign contributions disproportionately favor incumbents in most legislative elections, or that largely unregulated groups such as the now notorious 527s have as much impact on the outcome of a campaign as do the parties or the candidates' campaign organizations. These factors offer a very clear picture of the problems that underlay our much trumpeted electoral system. The second edition of this Very Short Introduction introduces the reader to these issues and more. Drawing on updated data and new examples from the 2016 presidential nominations, L. Sandy Maisel provides an insider's view of how the system actually works while shining a light on some of its flaws. He also illustrates the growing impact of campaigning through social media, the changes in campaign financing wrought by the Supreme Court recent decisions, and the Tea Party's influence on the sub-presidential nominating process. As the United States enter what is sure to be yet another highly contested election year, it is more important than ever that Americans take the time to learn the system that puts so many in power.

    Not only are galaxies fascinatingastronomical structures in themselves, but their study has revealed much of what we know today about the cosmos, providing a window on the Big Bang and the origins of the Universe. Gribben looks at our own Milky Way Galaxy in detail, from the different kinds of stars that are born within it, tothe origins of its magnificent spiral structure. Perhaps most interesting, Gribben describes the many exciting discoveries have been made about our own galaxy and about those beyond: how a supermassive black hole lurks at the center of every galaxy, how enormous forces are released when galaxiescollide, how distant galaxies provide a window on the early Universe, and how the formation of young galaxies shed needed light on the mysteries of Cold Dark Matter.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    It had a population of sixty million people spread across lands encircling the Mediterranean and stretching from northern England to the sun-baked banks of the Euphrates, and from the Rhine to the North African coast. It was, above all else, anempire of force--employing a mixture of violence, suppression, order, and tactical use of power to develop an astonishingly uniform culture.Here, historian Christopher Kelly covers the history of the Empire from Augustus to Marcus Aurelius, describing the empire's formation, and its political, religious, cultural, and social structures. It looks at the daily lives of the Empire's people: both those in Rome as well as those living in itsfurthest colonies. Romans used astonishing logistical feats, political savvy, and military oppression to rule their vast empire.

    Boyer provides a wide-ranging and authoritative history of America, capturing in a compact space the full story of our nation. Ranging from the earliest Native American settlers to the presidency of Barack Obama, this Very Short Introduction offers anilluminating account of politics, diplomacy, and war as well as the full spectrum of social, cultural, and scientific developments that shaped our country.Here is a masterful picture of America's achievements and failures, large-scale socio-historical forces, and pivotal events. Boyer sheds light on the colonial era, the Revolution and the birth of the new nation; slavery and the Civil War; Reconstruction and the Gilded Age; the Progressive era, theRoaring Twenties and the Great Depression; the two world wars and the Cold War that followed; right up to the tragedy of 9/11, the wars in Iraq and Afghanistan, and the epoch-making election of Barack Obama. Certain broad trends shape much of the narrative--immigration, urbanization, slavery, continental expansion, the global projection of U.S. power, the centrality of religion, the progression from an agrarian to an industrial to a post-industrial economic order. Yet in underscoring such large themes, Boyer also highlights the diversity of the American experience, the importance ofindividual actors, and the crucial role of race, ethnicity, gender, and social class in shaping the contours of specific groups within the nation's larger tapestry. And along the way, he touches upon the cultural milestones of American history, from Tom Paine's The Crisis to Allen Ginsberg's Howl.American History: A Very Short Introduction is a panoramic history of the United States, one that covers virtually every topic of importance--and yet can be read in a single day.

    It asks questions such as: Do animals have moral rights? If so, what does this mean? What sorts of mental lives do animals have, and how should we understand welfare? By presenting models for understanding animals' moral status and rights, and examining their mental lives and welfare, David DeGrazia explores the implications for how we should treat animals in connection with our diet, zoos, and research. Animal Rights distinguishes itself by combining intellectual rigor with accessibility, offering a distinct moral voice with a non-polemical tone.

    Featuring many striking photos, this Very Short Introduction offers a fascinating portrait of the unique world of each planet as well as an illuminating discussion of moons, asteroids, and Trans-Neptunian objects. Leading planetary scientist David A. Rothery, who has chaired the European Space Agency's Mercury surface and composition working group since 2007, gives a stimulating overview of the origin, nature, and evolution of our Solar System, including the controversial issues of what qualifies as a planet, and what conditions are required for a planetary body to support life. He explains how the surfaces of planets and moons have been sculpted by geology, weather, and impacts by meteors and asteroids. Rothery shows how our knowledge has advanced over the centuries, and how it has expanded at a dramatic rate in recent years, going far beyond our Solar System to explore planets orbiting distant stars.

    Now, in this superb compact history, Eric Rauchway offers an informed account of the New Deal and the Great Depression, illuminating its successes and failures.Rauchway first describes how the roots of the Great Depression lay in America's post-war economic policies--described as laissez-faire with a vengeance--which in effect isolated our nation from the world economy just when the world needed the United States most. He shows how the magnitude of theresulting economic upheaval, and the ineffectiveness of the old ways of dealing with financial hardships, set the stage for Roosevelt's vigorous (and sometimes unconstitutional) Depression-fighting policies. Indeed, Rauchway stresses that the New Deal only makes sense as a response to this globaleconomic disaster. The book examines a key sampling of New Deal programs, ranging from the National Recovery Agency and the Securities and Exchange Commission, to the Public Works Administration and Social Security, revealing why some worked and others did not. In the end, Rauchway concludes, it wasthe coming of World War II that finally generated the political will to spend the massive amounts of public money needed to put Americans back to work. And only the Cold War saw the full implementation of New Deal policies abroad--including the United Nations, the World Bank, and the InternationalMonetary Fund.Today we can look back at the New Deal and, for the first time, see its full complexity. Rauchway captures this complexity in a remarkably short space, making this book an ideal introduction to one of the great policy revolutions in history.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.

    Looking at texts ranging from the Gospels from NagHammadi to the Dialogues with the Risen Savior, Paul Foster shows how the apocryphal gospels reflect the diversity that existed within early Christianity, and considers the extent to which they can be used to reconstruct an accurate portrait of the historical Jesus. Foster demonstrates how closeanalysis of text, contents, and context are vital in assessing the value and authenticity of such ancient documents. Including discussions of controversies and case-studies such as the alleged hoax surrounding the discovery of Secret Mark, Foster concludes that the non-canonical texts, considered inthe correct context, can help us reach a more complete understanding of the multi-faceted nature of early Christianity.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    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.

    In this lively and accessible introduction, Graham Priest shows how wrong this conception is. He explores the philosophical roots of the subject, explaining how modern formal logic deals with issues ranging from the existence of God and the reality of time to paradoxes of probability and decision theory. Along the way, the basics of formal logic are explained in simple, non-technical terms, showing that logic is a powerful and exciting part of modern philosophy.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    Even the simplest system of cause and effect can be subject to chaos, denying us accurate predictions of its behaviour, and sometimes giving rise to astonishing structures of large-scale order. Our growing understanding of Chaos Theory is having fascinating applications in the real world - from technology to global warming, politics, human behaviour, and even gambling on the stock market. Leonard Smith shows that we all have an intuitive understanding of chaotic systems. He uses accessible maths and physics (replacing complex equations with simple examples like pendulums, railway lines, and tossing coins) to explain the theory, and points to numerous examples in philosophy and literature (Edgar Allen Poe, Chang-Tzu, Arthur Conan Doyle) that illuminate the problems. The beauty of fractal patterns and their relation to chaos, as well as the history of chaos, and its uses in the real world and implications for the philosophy of science are all discussed in this Very Short Introduction.

    In The Blues, Wald surveys a genre at the heart of American culture.It is not an easy thing to pin down. As Howlin' Wolf once described it, "When you ain't got no money and can't pay your house rent and can't buy you no food, you've damn sure got the blues." It has been defined by lyrical structure, or as a progression of chords, or as a set of practices reflecting West African "tonal and rhythmic approaches," using a five-note "blues scale." Wald sees blues less as a style than as a broad musical tradition within a constantly evolving pop culture. He traces its roots in work and praise songs, and shows how it was transformed by such professional performers as W. C. Handy, who first popularized the blues a century ago. He follows its evolution from Ma Rainey and Bessie Smith through Bob Dylan and Jimi Hendrix; identifies the impact of rural field recordings of Blind Lemon Jefferson, Charley Patton and others; explores the role of blues in the development of both country music and jazz; and looks at the popular rhythm and blues trends of the 1940s and 1950s, from the uptown West Coast style of T-Bone Walker to the "down home" Chicago sound of Muddy Waters. Wald brings the story up to the present, touching on the effects of blues on American poetry, and its connection to modern styles such as rap.As with all of Oxford's Very Short Introductions, The Blues tells you--with insight, clarity, and wit--everything you need to know to understand this quintessentially American musical genre.
