Get Up!: Why Your Chair Is Killing You and What You Can Do About It
by James A. LevineThat the average adult spends 50 to 70 percent of their day sitting is no surprise to anyone who works in an office environment. But few realize the health consequences they are suffering as a result of modernity's increasingly sedentary lifestyle, or the effects it has had on society at large. In Get Up! , health expert James A. Levine's original scientific research shows that today's chair-based world, where we no longer use our bodies as they evolved to be used, is having negative consequences on our health, and is a leading cause of diabetes, cancer, and heart disease. Over the decades, humans have moved from a primarily active lifestyle to one that is largely sedentary, and this change has reshaped every facet of our lives—from social interaction to classroom design. Levine shows how to throw off the shackles of inertia and reverse these negative trends through simple changes in our daily lives.
Dreamland of Humanists: Warburg, Cassirer, Panofsky, and the Hamburg School
by Emily J. LevineDeemed by Heinrich Heine a city of merchants where poets go to die, Hamburg was an improbable setting for a major intellectual movement. Yet it was there, at the end of World War I, at a new university in this commercial center, that a trio of twentieth-century pioneers in the humanities emerged. Working side by side, Aby Warburg, Ernst Cassirer, and Erwin Panofsky developed new avenues in art history, cultural history, and philosophy, changing the course of cultural and intellectual history in Weimar Germany and throughout the world. In Dreamland of Humanists, Emily J. Levine considers not just these men, but the historical significance of the time and place where their ideas took form. Shedding light on the origins of their work on the Renaissance and the Enlightenment, Levine clarifies the social, political, and economic pressures faced by German-Jewish scholars on the periphery of Germany’s intellectual world. By examining the role that context plays in our analysis of ideas, Levine confirms that great ideas—like great intellectuals—must come from somewhere.

Greater Ethiopia: The Evolution of a Multiethnic Society
by Donald N. LevineGreater Ethiopia combines history, anthropology, and sociology to answer two major questions. Why did Ethiopia remain independent under the onslaught of European expansionism while other African political entities were colonized? And why must Ethiopia be considered a single cultural region despite its political, religious, and linguistic diversity? Donald Levine's interdisciplinary study makes a substantial contribution both to Ethiopian interpretive history and to sociological analysis. In his new preface, Levine examines Ethiopia since the overthrow of the monarchy in the 1970s. "Ethiopian scholarship is in Professor Levine's debt. . . . He has performed an important task with panache, urbanity, and learning."—Edward Ullendorff, Times Literary Supplement "Upon rereading this book, it strikes the reader how broad in scope, how innovative in approach, and how stimulating in arguments this book was when it came out. . . . In the past twenty years it has inspired anthropological and historical research, stimulated theoretical debate about Ethiopia's cultural and historical development, and given the impetus to modern political thinking about the complexities and challenges of Ethiopia as a country. The text thus easily remains an absolute must for any Ethiopianist scholar to read and digest."-J. Abbink, Journal of Modern African Studies
The Future Is Present: Art, Technology, and the Work of Mobile Image (Leonardo)
by Cary Levine Philip GlahnA critical history of the pioneering art and technology group Mobile Image and their prescient work in communications, networking, and information systems.In The Future Is Present, Philip Glahn and Cary Levine tell the fascinating history of the visionary art group Mobile Image—founded by Kit Galloway and Sherrie Rabinowitz in 1977—which appropriated emerging technologies, from satellites to electronic message platforms. Based in Los Angeles, this under-studied collective worked amid urban crisis, a techno-boom, consolidating media power, and ascendant neoliberal politics. Mobile Image challenged fundamental conventions of the public sphere, democracy, communication, and political participation, as well as notions of power, representation, and identity.Glahn and Levine argue not only for the historical importance of Mobile Image, but also for a critical artistic process that is at once analytic and transformative. They weave themes such as embodiment and its mediation, public/private dialectics, and techno-utopian vision throughout the book, binding these projects to discourses around race, gender, and class, as well as margin and center, the local and the global. In today&’s world of ubiquitous digital re/production, networking, and social media, The Future Is Present shows how the work of Mobile Image continues to have profound implications for art, technology, and the politics of public and private experience.

American Covenant: How the Constitution Unified Our Nation—and Could Again
by Yuval Levin&“The most important voice in the political culture&” (Ben Shapiro) reveals the Constitution&’s remarkable power to repair our broken civic culture, rescue our malfunctioning politics, and unify a fractious America Common ground is hard to find in today&’s politics. In a society teeming with irreconcilable political perspectives, many people have grown frustrated under a system of government that constantly demands compromise. More and more on both the right and the left have come to blame the Constitution for the resulting discord. But the Constitution is not the problem we face; it is the solution. Blending engaging history with lucid analysis, conservative scholar Yuval Levin&’s American Covenant recovers the Constitution&’s true genius and reveals how it charts a path to repairing America&’s fault lines. Uncovering the framers&’ sophisticated grasp of political division, Levin showcases the Constitution&’s exceptional power to facilitate constructive disagreement, negotiate resolutions to disputes, and forge unity in a fractured society. Clear-eyed about the ways that contemporary politics have malfunctioned, Levin also offers practical solutions for reforming those aspects of the constitutional order that have gone awry. Hopeful, insightful, and rooted in the best of our political tradition, American Covenant celebrates the Constitution&’s remarkable power to bind together a diverse society, reassuring us that a less divided future is within our grasp.

The Remarkable Education of John Quincy Adams
by Phyllis Lee LevinA patriot by birth, John Quincy Adams's destiny was foreordained. He was not only "The Greatest Traveler of His Age," but his country's most gifted linguist and most experienced diplomat. John Quincy's world encompassed the American Revolution, the War of 1812, and the early and late Napoleonic Age. As his diplomat father's adolescent clerk and secretary, he met everyone who was anyone in Europe, including America's own luminaries and founding fathers, Franklin and Jefferson. All this made coming back to America a great challenge. But though he was determined to make his own career he was soon embarked, at Washington's appointment, on his phenomenal work abroad, as well as on a deeply troubled though loving and enduring marriage. But through all the emotional turmoil, he dedicated his life to serving his country. At 50, he returned to America to serve as Secretary of State to President Monroe. He was inaugurated President in 1824, after which he served as a stirring defender of the slaves of the Amistad rebellion and as a member of the House of Representatives from 1831 until his death in 1848. In The Remarkable Education of John Quincy Adams, Phyllis Lee Levin provides the deeply researched and beautifully written definitive biography of one of the most fascinating and towering early Americans.
Economic Evaluation in Education: Cost-Effectiveness and Benefit-Cost Analysis
by Henry M. Levin Patrick J. McEwan Clive R. Belfield A. Brooks Bowden Robert D. ShandThe past decade has seen increased attention to cost-effectiveness and benefit-cost analysis in education as administrators are being asked to accomplish more with the same or even fewer resources, philanthropists are keen to calculate their "return on investment" in social programs, and the general public is increasingly scrutinizing how resources are allocated to schools and colleges. This text (titled Cost-Effectiveness Analysis in its previous editions) is the only full-length book to provide readers with the step-by-step methods they need to plan and implement a benefit-cost analysis in education. The authors examine a range of issues, including how to identify, measure, and distribute costs; how to measure effectiveness, utility, and benefits; and how to incorporate cost evaluations into the decision-making process. The updates to the Third Edition reflect the considerable methodological development in the evaluation literature, and the greater empiricism practiced by education researchers, to help readers learn to apply more advanced methods to their own analyses. SAGE congratulates author Henry M. Levin, winner of the 2017 AERA Distinguished Contributions to Research in Education Award.

Women’s Behavioral Health: A Public Health Perspective
by Bruce Lubotsky Levin Ardis HansonThis book examines women's behavioral health (defined as alcohol, drug use, and mental health) problems from a population or public health perspective. It provides the current state of knowledge for women’s behavioral health and examines the need for behavioral health services and implications for policy. It also reviews major issues in the organization, financing, and provision of women’s behavioral health services. Global and national studies show that women are nearly twice as likely as men to have selected mental disorders. There also has been increasing attention to the social, behavioral, institutional, and economic determinants of health that result in service inequities for women in the United States compared to women in other countries. This textbook highlights mental and substance use disorders of particular concern to women, emphasizes services research issues in women’s behavioral health, incorporates the social determinants of health, and provides a discussion of these critical issues from an interprofessional and interdisciplinary public health perspective. It also presents an overview of the epidemiology of mental and substance use disorders across the lifespan of women and service delivery issues from a population and system-level perspective. Applied services research chapters comprise the book's 14 chapter contributions that are organized into three parts: Part I. Framing Women’s Behavioral Health; Part II. Selected At-Risk Populations; and Part III. Services Delivery issues. Women's Behavioral Health: A Public Health Perspective is a textbook for advanced undergraduate and graduate students in many academic disciplines, including the social and behavioral sciences, public health, women’s studies, medical anthropology, and medical sociology. It also is useful for postdoctoral students in public health, population health, and the health professions. This volume can serve as a reference book for academicians and researchers in community and social psychology, community health, community nursing, community and preventive medicine, and public health; practitioners and policymakers at various levels of government; and behavioral health professionals at mental health and substance use programs in various national and global healthcare organizations.
Insiders' French: Beyond the Dictionary (The\nature Of Human Society Ser.)
by Eleanor Levieux Michel LevieuxIf you had been living in France in the 1990s, the language you would have heard on the radio and television or seen in the newspapers would be far removed from the French language of ten or twenty years ago. The country and its language have changed tremendously in a relatively short period of time, and, as a result, English speakers with a grounding in French can still find themselves struggling to understand terms commonly encountered in contemporary French society. Luckily, Eleanor and Michel Levieux now bring us up to date with their Insiders' French, an utterly entertaining and informative guide to the language of the "new France." This "new France" is a country poised to experience the European single currency but uncertain about being part of Europe. It is hooked on fast food but ambivalent about the country where it originated. France today has record unemployment and an increasingly controversial immigrant population. Clearly, given the rapidly changing conditions and lifestyles, conventional French dictionaries alone cannot completely inform readers and visitors. Insiders' French offers a solution to the incomprehension, a unique handbook in which you'll find the language of European union, the space program, abortion and women's rights, high-tech industries, and health care, among other topics. Entries proceed by association of ideas and related terms, with extensive cross-referencing, while still being alphabetized for easy reference like a standard dictionary. Cartoons from major French journals add to your understanding and enjoyment.Insiders' French opens up the secret territory of French politics and culture that is often not understood by visitors or students, and it does so with wit and verve—qualities that remain in the French language despite its recent changes.
Seductive Journey: American Tourists in France from Jefferson to the Jazz Age
by Harvey LevensteinFor centuries, France has cast an extraordinary spell on travelers. Harvey Levenstein's Seductive Journey explains why so many Americans have visited it, and tells, in colorful detail, what they did when they got there. The result is a highly entertaining examination of the transformation of American attitudes toward French food, sex, and culture, as well as an absorbing exploration of changing notions of class, gender, race, and nationality. Levenstein begins in 1786, when Thomas Jefferson instructed young upper-class American men to travel overseas for self-improvement rather than debauchery. Inspired by these sentiments, many men crossed the Atlantic to develop "taste" and refinement. However, the introduction of the transatlantic steamship in the mid-nineteenth century opened France to people further down the class ladder. As the upper class distanced themselves from the lower-class travelers, tourism in search of culture gave way to the tourism of "conspicuous leisure," sex, and sensuality. Cultural tourism became identified with social-climbing upper-middle-class women. In the 1920s, prohibition in America and a new middle class intent on "having fun" helped make drunken sprees in Paris more enticing than trudging through the Louvre. Bitter outbursts of French anti-Americanism failed to jolt the American ideal of a sensual, happy-go-lucky France, full of joie de vivre. It remained Americans' favorite overseas destination. From Fragonard to foie gras, the delicious details of this story of how American visitors to France responded to changing notions of leisure and blazed the trail for modern mass tourism makes for delightful, thought-provoking reading. "...a thoroughly readable and highly likable book."—Deirdre Blair, New York Times Book Review
Israel’s Day of Light and Joy: The Origin, Development, and Enduring Meaning of the Jewish Sabbath
by Jon D. LevensonThis book begins by exploring the mysterious origins of an institution so familiar that most of us never wonder where it came from—the seven-day week. Jon D. Levenson then focuses on the historical development of the Jewish Sabbath and the rich range of theological and ethical meanings it has acquired over the centuries.Levenson evaluates the theory that the Hebrew word šabbāt derives from Akkadian and that the Sabbath may have begun as a day of ill omen, only later to be reinterpreted as the joyous festival that consummates the seven-day week. He explores the quasi-magical character of the number seven in ancient Near Eastern and Mediterranean compositions and examines the revealing variation of the Sabbath commandment between the two biblical versions of the Decalogue in Exodus and Deuteronomy. He also treats sabbatical law in the Second Temple and rabbinic periods, critiquing contemporary efforts to extract a spirituality from the Sabbath that is divorced from larger questions of communal identity, normative practice, and religious affirmation. Levenson concludes by discussing modern challenges to Sabbath observance and the surprising prospects for its continuation.Written by an eminent scholar in the field, this sophisticated inquiry bridges the gap between studies that explore the spiritual meaning of Jewish Sabbath observance and those that focus strictly on the history of the tradition. It will appeal to a wide audience of academics and lay readers.

Partisan Hostility and American Democracy: Explaining Political Divisions and When They Matter (Chicago Studies in American Politics)
by Matthew Levendusky James N. Druckman John Barry Ryan Samara Klar Yanna KrupnikovAn unflinching examination of the effects and boundaries of partisan animosity. For generations, experts argued that American politics needed cohesive parties to function effectively. Now many fear that strong partisan views, particularly hostility to the opposing party, are damaging democracy. Is partisanship as dangerous as we fear it is? To provide an answer, this book offers a nuanced evaluation of when and how partisan animosity matters in today’s highly charged, dynamic political environment, drawing on panel data from some of the most tumultuous years in recent American history, 2019 through 2021. The authors show that partisanship powerfully shapes political behaviors, but its effects are conditional, not constant. Instead, it is most powerful when politicians send clear signals and when an issue is unlikely to bring direct personal consequences. In the absence of these conditions, other factors often dominate decision-making. The authors argue that while partisan hostility has degraded US politics—for example, politicizing previously non-political issues and undermining compromise—it is not in itself an existential threat. As their research shows, the future of American democracy depends on how politicians, more than ordinary voters, behave.
