Now, in The American Presidency, presidential authority Charles O. Jones provides invaluable background to the current controversy, in a compact, reliable guide to the office of the chief executive.This marvelously concise survey is packed with information about the presidency, some of it quite surprising. We learn, for example, that the Founders adopted the word president over governor and other alternatives because it suggested a light hand, as in one who presides, rather than rules. Indeed, the Constitutional Convention first agreed to a weak chief executive elected by congress for one seven-year term, later calling for independent election and separation of powers. Jones sheds much light on how assertive leaders, such as Andrew Jackson, Theodore Roosevelt, and FDR enhanced the power of the presidency, and illuminating how such factors as philosophy (Reagan's anti-Communist conservatism), the legacy of previous presidencies (Jimmy Carter following Watergate), relations with Congress, and the impact of outside events have all influenced presidential authority. He also explores the rise of federal power and the dramatic expansion of federal agencies, showing how the president takes a direct hand in this vast bureaucracy, and he examines the political process of selecting presidents, from the days of deadlocked conventions to the rise of the primary after World War II.In 200 years, he writes, the presidency had changed from that of a person--Washington followed by Adams, then Jefferson--to a presidential enterprise with a cast of thousands. Jones explains how this remarkable expansion has occurred and where it may lead in the future.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    In this Very Short Introduction, engineer David Muir Wood turns a spotlight on a field that we often take for granted. He sheds light on the nature and importance of civil engineering in the history of civilization and urbanization, outlines its many accomplishments in the modern era, and points to the hurdles that civil engineering will face in the future. Beginning with the task of creating a settlement on a deserted island, Muir Wood sets out the problems that civil engineers face every day, highlighting the social and environmental challenges as well as the grasp of science and technology needed to craft buildings, bridges, tunnels, houses, and areas of recreation. The author also profiles the lives of some of the major civil engineers, such as Isambard Kingdom Brunel, the acclaimed builder of steamships, railways, and tunnels, and Sir Joseph Bazalgette, whose sewer system in central London was instrumental in relieving the city from cholera epidemics. Finally, Muir Wood considers the growing difficulty of managing our water and energy supplies, and he looks at the engineering profession's increased sensitivity to building and the environment.

    Was late antiquity therefore merely a time of decline? In this vibrant and compact introduction, Gillian Clark shedslight on the concept of late antiquity and the events of its time, showing that this was in fact a period of great transformation. Late antiquity saw Roman law codified, Christian creeds formulated, the Talmud compiled, and the Qur'an composed. If the Goths sacked the city of Rome, the Vandalsbuilt churches in Africa and Attila the Hun received an embassy from Constantinople. Anthony of Egypt and Simeon Stylites offered spectacular new models of holiness, while Augustine and Basil and Benedict devised rules for monastic communities. Late antique artists produced the mosaics of Ravennaand the first dome of Hagia Sophia. And it was also the period when emperors Diocletian in the third century and Justinian in the sixth enacted extensive and much-needed reforms of government.

    Discussing not only the main academic theories, but also the practical problems and issues, Wilkinson considers key normative questions, such as how the international state system might be reformed so that international relations are improved.

    From humble beginnings on the seven hills beside the Tiber, the city of Rome grew to dominate the ancient Mediterranean. Led by her senatorial aristocracy, Republican armies defeated Carthage and the successor kingdoms of Alexander the Great, and brought the surrounding peoples to east and west into the Roman sphere. In this Very Short Introduction, David M. Gwynn provides a fascinating introduction to the history of the Roman Republic, ranging from the origins of Rome and the vivid Roman legends that surround the foundations of the city, to the overthrow of the monarchy in 509 BC, the five hundred years of republican rule, the rise of Julius Caesar and Caesar Augustus, and the establishment of the Principate. Gwynn considers the political structure of the Republic, including its unique constitution, and he highlights literary and material sources, bringing to life the culture and society of Republican Rome. He also reflects on the Roman values and beliefs of the time, in order to shed light on the Republic's dramatic rise and fall. Finally, Gwynn reflects on the remarkable legacy of the Roman Republic, including its modern-day resonance and legacy in literature and in film, where it is often presented as a model, a source of inspiration, but also a warning.

    In many European countries, they provided the stimulus for radical social and political change--particularly in Spain, Germany, and Italy--and are frequently viewed in these places as the starting point of their modern histories. In this Very Short Introduction, Mike Rapport provides a compact overview of these pivotal wars. He begins with the French Revolution and the French Revolutionary wars of 1792-1803, which set the stage for the rise of Napoleon, and then examines the Napoleonic Wars in two acts--the years in which the French dominated the European landscape and the years when an allied Europe fought back, leading to Napoleon's final defeat at the Battle of Waterloo. Rapport sheds light on the social, political, and institutional aspects of warfare in the Napoleonic era, and he provides a fascinating discussion of the ways and means with which these wars were fought, looking at the tactics, strategies, and weaponry of the time. Finally, he illuminates the significance of the wars, and their legacy, in both specific national contexts and from a wider global perspective.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.

    But away from shock tactics in the gallery, there are many unanswered questions. Who is really running the art world? What effect has America's growing political and cultural dominance had on art?Here Julian Stallabrass takes us inside the international art world to answer these and other controversial questions, and to argue that behind contemporary art's variety and apparent unpredictability lies a grim uniformity. Its mysteries are all too easily explained, its depths much shallower thanthey seem. Contemporary art seeks to bamboozle its viewers while being the willing slave of business and government. This book is your antidote and will change the way you see contemporary art.About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics.

    During his time as a lawyer in South Africa he developed his strategy of non-violence: the idea of opposing unjust laws bynon-violent protest. He led the Indian National Congress party in three major campaigns against British rule, each culminating in his arrest.In Gandhi, a short introduction to Gandhi's life and thought, Bhikhu Parekh outlines both Gandhi's major philosophical insights and the limitations of his thought. Written with extensive access to Gandhi's writings in Indian languages to which most commentators have little or no access, Parekh looksat Gandhi's cosmocentric anthropology, his spiritual view of politics, and his theories of oppression, non-violent action, and active citizenship. He also considers how the success of Gandhi's principles were limited by his lack of coherent theories of evil, and of state and power. Gandhi's view ofman as ascetic allows no room for expressions of the cultural, artistic, or intellectual. Furthermore, he was so hostile to modern civilization that he was unable to appreciate its complex dialectic or offer a meaningful narrative.Nevertheless, Gandhi's life and thought had an enormous impact on the Indian nation, and he continues to be widely revered--known before and after his assassination as Mahatma, the Great Soul.

    He also looks at philosophical issues in particular sciences, including the problem of classification in biology, and the nature of space and time in physics.

    Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before.In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages.Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.”Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China.An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come.
