Stories of long-lived animal species—from thousand-year-old tubeworms to 400-year-old sharks—and what they might teach us about human health and longevity. Opossums in the wild don’t make it to the age of three; our pet cats can live for a decade and a half; cicadas live for seventeen years (spending most of them underground). Whales, however, can live for two centuries and tubeworms for several millennia. Meanwhile, human life expectancy tops out around the mid-eighties, with some outliers living past 100 or even 110. Is there anything humans can learn from the exceptional longevity of some animals in the wild? In Methusaleh’s Zoo, Steven Austad tells the stories of some extraordinary animals, considering why, for example, animal species that fly live longer than earthbound species and why animals found in the ocean live longest of all. Austad—the leading authority on longevity in animals—argues that the best way we will learn from these long-lived animals is by studying them in the wild. Accordingly, he proceeds habitat by habitat, examining animals that spend most of their lives in the air, comparing insects, birds, and bats; animals that live on, and under, the ground—from mole rats to elephants; and animals that live in the sea, including quahogs, carp, and dolphins. Humans have dramatically increased their lifespan with only a limited increase in healthspan; we’re more and more prone to diseases as we grow older. By contrast, these species have successfully avoided both environmental hazards and the depredations of aging. Can we be more like them?
The most comprehensive and authoritative reference available today on colorectal surgery This revised fourth edition of Gordon and Nivatvongs' Principles and Practice of Surgery for the Colon, Rectum, and Anus edited by David Beck, Steven Wexner, and Janice Rafferty strikes a perfect balance between evidence-based medicine, in-depth details, and clinical pearls. The result is a highly engaging and authoritative tome in the grand tradition of Philip Gordon and Santhat Nivatvongs. Building on the widely acclaimed previous editions' reputation for superb quality and reader-friendliness, the fourth edition includes contributions from an expanded cadre of internationally known experts. Significant advances have been made in this field since the third edition was published. The latest diagnostic modalities are highlighted such as MRI, CT angiography, and enterography. The first section covers essentials such as anatomy, physiology, diagnosis, colonoscopy, and patient management. Sections two through four discuss a full spectrum of anorectal diseases, colorectal disorders, trauma, unexpected challenges, and complications. Among the additions are expanded sections on transanal total mesorectal excision, genetics, personalized medicine, "wait and watch" principles, outpatient management of anorectal surgery, and large bowel obstruction. Key Highlights Thirty-seven chapters cover a wide array of gastrointestinal disorders such as fecal incontinence, ulcerative colitis, Crohn's disease, diverticulitis, carcinomas, and other malignant lesions A multidisciplinary team approach to rectal cancer encompasses rectal cancer protocol MRI, synoptic reporting, and various neoadjuvant therapy protocols The use of cutting-edge approaches including laparoscopy, robotics, hyperbaric oxygen, and radiofrequency tissue remodeling Superb full-color plates, illustrations, photographs, diagrams, detailed tables, graphics, and surgical videos elucidate underlying disease and management As the most comprehensive resource on colorectal surgery available on the market today, this is a must-have for every colon and rectal surgeon – from residents to veteran practitioners.
One of the most persistent controversies of modern science has dealt with human visual perception. It erupted in Germany during the 1860s as a dispute between physiologists Hermann von Helmholtz, Ewald Hering, and their schools. Well into the twentieth century these groups warred over the origins of our capacity to perceive space, over the retinal mechanisms that mediate color sensations, and over the role of mind, experience, and inference in vision. Here R. Steven Turner explores the impassioned exchanges of those rival schools, both to illuminate the clash of theory and to explore the larger role of controversy in the development of science. Controversy, he suggests, is constitutive of scientific change, and he uses the Helmholtz-Hering dispute to illustrate how polemics and tacit negotiation shape evolving theoretical stances. Turner focuses on the arguments and issues of the dispute, issues that ranged from the interpretation of color blindness and optical illusions to the therapeutic practices of clinical ophthalmology. As well, he focuses on the personalities, institutions, disciplinary structures, and methodological commitments that shaped the dispute, including the schools' rhetorical strategies. He explores the incommensurability of the protagonists' viewpoints and examines the reception of the theories and the changing fortunes of the schools. Finally, Turner traces the controversy into the twentieth century, where the issues continue to inform the study of vision today. Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
NEW YORK TIMES BESTSELLER • A call to reform our antiquated political institutions before it’s too late—from the authors of How Democracies Die “[Levitsky and Ziblatt] write with terrifying clarity about how the forces of the right have co-opted the enshrined rules to exert their tyranny.”—The Washington Post ONE OF THE CALIFORNIA REVIEW OF BOOKS’ TEN BEST BOOKS OF THE YEAR • A NEWSWEEK BEST BOOK OF THE YEAR America is undergoing a massive experiment: It is moving, in fits and starts, toward a multiracial democracy, something few societies have ever done. But the prospect of change has sparked an authoritarian backlash that threatens the very foundations of our political system. Why is democracy under assault here, and not in other wealthy, diversifying nations? And what can we do to save it? With the clarity and brilliance that made their first book, How Democracies Die, a global bestseller, Harvard professors Steven Levitsky and Daniel Ziblatt offer a coherent framework for understanding these volatile times. They draw on a wealth of examples—from 1930s France to present-day Thailand—to explain why and how political parties turn against democracy. They then show how our Constitution makes us uniquely vulnerable to attacks from within: It is a pernicious enabler of minority rule, allowing partisan minorities to consistently thwart and even rule over popular majorities. Most modern democracies—from Germany and Sweden to Argentina and New Zealand—have eliminated outdated institutions like elite upper chambers, indirect elections, and lifetime tenure for judges. The United States lags dangerously behind. In this revelatory book, Levitsky and Ziblatt issue an urgent call to reform our politics. It’s a daunting task, but we have remade our country before—most notably, after the Civil War and during the Progressive Era. And now we are at a crossroads: America will either become a multiracial democracy or cease to be a democracy at all.
Art, History, and the Historiography of Judaism in Roman Antiquity explores the complex interplay between visual culture, texts, and their interpretations, arguing for an open-ended and self-aware approach to understanding Jewish culture from the first century CE through the rise of Islam. The essays assembled here range from the “thick description” of Josephus’s portrayal of Bezalel son of Uri as a Roman architect through the inscriptions of the Dura Europos synagogue, Jewish reflections on Caligula in color, the polychromy of the Jerusalem temple, new-old approaches to the zodiac, and to the Christian destruction of ancient synagogues. Taken together, these essays suggest a humane approach to the history of the Jews in an age of deep and long-lasting transitions—both in antiquity, and in our own time. "Taken as a whole, Fine’s book exhibits the value of bridging disciplines. The historiographical segments integrated throughout this volume offer essential insights that will inform any student of Roman and late antiquity." Yael Wilfand, Hebrew University, Review of Biblical Literature, 2014.
