This book offers a novel treatment of one of the most important and long-standing research agendas in critical political economy: the theorizing of stages of capitalist development. Albritton advances the work of Japanese economist, Kozo Uno, to explore capital accumulation and its ideological, legal and political supports, not only in the stages of mercantilism, liberalism and imperialism, but also in the post-World War II capitalist stage of consumerism. The power of Albritton’s adoption of this Japanese approach resides in the crisp clarity it achieves over the way stage theorizing of capitalism draws on both economic theory and historical analysis. In the new, fully revised edition, written with Richard Westra, two new chapters are added. One meticulously examines the tendencies of capitalism euphemized as globalization and financialization which followed the crisis of the stage of consumerism. The other deals with current threats to civilization posed by burgeoning militarism, environmental destruction and climate apocalypse. The concluding chapter argues for the necessity of major social change to ensure a liveable future for humanity. The book will be of interest to researchers and students of political economy and the history of economic thought, as well as a wider audience interested in the transformation and crises of capitalism.
This book offers a critical edition of the petitions in their original Italian language that (Catholic) Jews residing in Italy submitted to the Fascist General Administration for Demography and Race (Demorazza) in order either to be “discriminated,” i.e., not subjected to various provisions of Mussolini’s racial laws.
A proposal for a philosophical foundation and a realistic deliberative mechanism for creating a transnational common law for the environment. In Global Democracy and Sustainable Jurisprudence, Walter Baber and Robert Bartlett explore the necessary characteristics of a meaningful global jurisprudence, a jurisprudence that would underpin international environmental law. Arguing that theories of political deliberation offer useful insights into the current “democratic deficit” in international law, and using this insight as a way to approach the problem of global environmental protection, they offer both a theoretical foundation and a realistic deliberative mechanism for creating effective transnational common law for the environment. Their argument links elements not typically associated: abstract democratic theory and a practical form of deliberative democracy; the legitimacy-imparting value of deliberative democracy and the possibility of legislating through adjudication; common law jurisprudence and the development of transnational environmental law; and conceptual thinking that draws on Deweyan pragmatism, Rawlsian contractarianism, Habermasian critical theory, and the full liberalism of Bohman, Gutmann, and Thompson. Baber and Bartlett offer a democratic method for creating, interpreting, and implementing international environmental norms that involves citizens and bypasses states—an innovation that can be replicated and deployed across a range of policy areas. Transnational environmental consensus would develop through a novel model of juristic democracy that would generate legitimate international environmental law based on processes of hypothetical rule making by citizen juries. This method would translate global environmental norms into international law—law that, unlike all current international law, would be recognized as both fact and norm because of its inherent democratic legitimacy.
In 1906, Sir George Newman's 'Infant Mortality: A Social Problem', one of the most important health studies of the twentieth century, was published. To commemorate this anniversary, this volume brings together an interdisciplinary team of leading academics to evaluate Newman's critical contribution, to review current understandings of the history of infant and early childhood mortality, especially in Britain, and to discuss modern approaches to infant health as a continuing social problem. The volume argues that, even after 100 years of health programmes, scientific advances and medical interventions, early childhood mortality is still a significant social problem and it also proposes new ways of defining and tracking the problem of persistent mortality differentials.
In February 1945, Israele Zolli, chief rabbi of Rome's ancient Jewish community, shocked his co-religionists in Italy and throughout the Jewish world by converting to Catholicism and taking as his baptismal name, Eugenio, to honor Pope Pius XII (Eugenio Pacelli) for what Zolli saw as his great humanitarianism toward the Jews during the Holocaust. Almost a half a century after his conversion, Zolli still evokes anger and embarrassment in Italy's Jewish community. This book is the first authoritative treatment of this astonishing story. What induced Zolli to embrace Catholicism will probably never be known. Nonetheless, by painstaking scholarly detective work, through interviews in Italy and elsewhere, through the unearthing of private papers not previous known to exist, and through the study of previous inaccessible archival materials, the authors have succeeded in explaining why Zolli left the Jewish fold and joined the Catholic Church. Like Zolli's rabbinical career, Pius XII's long pontificate tells us much about the Church of Rome and its relationship to the Jewish people, particularly with reference to the issue of conversion. The authors focus on the pontiff's World War II policies vis-à-vis the Jews, a subject that has been heatedly debated since Rolf Hochhuth's The Deputy was performed in the early 1960s. What Pacelli knew abut the extermination of the Jews and when he knew it, what he said and failed to say, are given special attention in this book. Through the examination of previous scholarship and primary materials (including Pius XI's encyclical on race and anti-Semitism, Pacelli's behavior is evaluated to determine if Zolli accurately gauged the Holy Father's efforts to save Jews. This saga of the two Eugenios will interest historians of the Second World War and the Holocaust and students of history alike.
How have global markets and global manufacturing changed the balance of social, economic and political power? With this volume Ross and Trachte challenge existing political-economic theory. In concise terms they show how traditional theories of monopoly capitalism and world systems are not well-suited to analyze the emergence of global capitalism. This book, in a series of case studies of U.S. metropolitan areas, examines the dramatic transformation of the world economy in the last two decades. The book's last section examines political strategy and the political theory implied by the heightened power of capital.
This book presents a quantitative treatment of the theory and natural variations of light stable isotopes. It discusses isotope distribution in the context of fractionation processes, thermodynamics, mass conservation, exchange kinetics, and diffusion theory, and includes more than 100 original equations. The theoretical principles are illustrated with natural examples that emphasize oxygen and hydrogen isotope variations in natural waters, terrestrial and extraterrestrial rocks, and hydrothermal systems. New data on meteoric precipitation, rivers, springs, formation fluids, and hydrothermal systems are included in relation to various natural phenomena. Essentially, this book seeks to reconnect the diverse phenomenological observations of isotope distribution to the quantitative theories of physical chemistry and the language of differential equations. It may serve as a textbook for advanced students, as a research reference, or as a quick source of information. The book is organized into five chapters, each followed by suggested quantitative problems and a short reference list. The three theoretical chapters progress from an elementary review of the physical chemistry of stable isotopes, to the thermodynamics of isotopic compounds, and finally to the calculation of isotope distribution in dynamic systems. The third and fifth chapters emphasize oxygen and hydrogen isotope variations in Earth's hydrosphere and lithosphere, constituting the most important examples of the theoretical principles. Appendices provide data on atomic weights of light elements, physical constants, mathematical relationships, and isotopic fractionation factors.
Our world seems entangled in systems increasingly dominated by power, greed, ignorance, self-deception and denial, with spiralling inequity and injustice. Against a backdrop of climate change, failing ecosystems, poverty, crushing debt and corporate exploitation, the future of our world looks dire and the solutions almost too monumental to consider. Yet all is not lost. Robert Chambers, one of the ?glass is half full? optimists of international development, suggests that the problems can be solved and everyone has the power at a personal level to take action, develop solutions and remake our world as it can and should be. Chambers peels apart and analyses aspects of development that have been neglected or misunderstood. In each chapter, he presents an earlier writing which he then reviews and reflects upon in a contemporary light before harvesting a wealth of powerful conclusions and practical implications for the future. The book draws on experiences from Africa, Asia and elsewhere, covering topics and concepts as wide and varied as irreversibility, continuity and commitment; administrative capacity as a scarce resource; procedures and principles; participation in the past, present and future; scaling up; behaviour and attitudes; responsible wellbeing; and concepts for development in the 21st century.
New York Times Bestselling author! Over a decade ago, following a rise in developmental disorders such as autism and ADHD, the mercury-containing preservative Thimerosal was widely believed to have been eliminated from vaccine supplies. However, dangerous quantities of Thimerosal continue to be used, posing a threat to public health In this groundbreaking book, Robert F. Kennedy, Jr., and Dr. Mark Hyman examine the research literature on Thimerosal and make a very clear statement about its potentially dangerous effects. In the past, the CDC, FDA, NIH, and AAP, as well as the US Congress, the American Academy of Family Physicians, the US Department of Agriculture, the European Medicines Agency, and the California Environmental Protection Agency have expressed concerns over the use of Thimerosal in vaccines. But despite the many voices calling for action, the media and policy makers have repeatedly failed to adequately address the issue. Now, with Thimerosal: Let the Science Speak, the goals are to educate parents, doctors, and health policy makers; to eliminate this toxic chemical from the world’s vaccine supplies; to move toward safer alternatives; and to maintain or increase vaccination rates critical to the United States and developing nations. With safer options available, parents shouldn’t have to worry about the devastating effects of vaccinating their children.
Remember the pots hammered by spoons from high Manhattan windows, and parades of cars and pick-up trucks holding dear the medical professionals responding to covid-19. This book is part of that chorus, that march, to express appreciation for the giving of care. And beyond doctors and nurses, bless their hearts, to mothers caring for their babies, for captains for their teams, for the soon-to-be widowers for their wives and teachers for their students, but also for the ranchers for their cattle and the contemplative world for our environment. This is a book to think more closely of the support for care, individual as it so often will be, to be woven more closely together in a paradigm of care. Care is always prominent. Care for others, of the family, care for those of the tribe, care for animals and homes and gardens and properties, self-care. And the purse. Even without teaching, compensation, or legislation, care survives, but even with these helpings, it falls short of the need. We live in a crisis of care. Thinking explicitly and beyond health care. There is no mechanism of state and conscience that delivers care to all the venues of need, and seldom in the amounts needed. The reservoirs of care are far from empty, but at a mark that needs topping up. There is need for care advocacy, a care ethic, a paradigm. This book is about that paradigm. A care paradigm may bring comfort and recovery more fully to the people and organic creations of the world. The paradigm hears the moan of indifference. It draws upon the eyes of the heart. The paradigm is about how we see the need for care. The care paradigm, the grand beholding, is manifest in how we provide for others, how we nurture them, give succor, how we are disposed, and are not, to sacrifice to relieve their hurt. It is not only caring for those visibly needing care, unable to care for themselves, but caring for all. It is having a disposition that the hurts, large and small, that all of us carry, arouse concern and appreciation from and for each individual, the community and the world.
Cooter and Schfer provide a thorough introduction to growth economics through the lens of law and economics. They do a masterful job of weaving in historical anecdotes from all over the world, detailed discussions of historical transformations, theoretical literature, empirical studies, and numerous clever hypotheticals. Scholars as well as general readers will find this book to be very useful and informative."--Henry N. Butler, George Mason University -- "This book distills and presents in a lucid and often even entertaining way the main insights and contributions of law and economics to meeting the challenges of growth for developing countries. Cooter and Schfer argue that market freedom is the key to growth, but that it needs to be sustained by the appropriate legal rules and institutions."--Robert Howse, coauthor of "The Regulation of International Trade.
The ongoing financial crisis has raised questions about the underpinnings of development assistance and the role of international financial institutions. A new development assistance framework, grounded in partnership, is emerging. That is the backdrop for this year's review, which--as in past years--tracks the World Bank's operational performance based on the findings of recent evaluations. After the backdrop provided in chapter one, the chapters that follow review recent evidence about the Bank's development effectiveness. Chapter 2 describes project and sector performance trends. Chapter 3 considers recent evaluation lessons at the country level. It draws on OED's (Operations Evaluation Department) country assistance evaluations to help draw out the lessons of the ongoing crisis. Chapter 4 draws lessons that can be inferred from thematic studies. The final chapter discusses the implications for Bank operations and evaluation.

The Holocaust in Italian Culture, 1944–2010 is the first major study of how postwar Italy confronted, or failed to confront, the Holocaust. Fascist Italy was the model for Nazi Germany, and Mussolini was Hitler's prime ally in the Second World War. But Italy also became a theater of war and a victim of Nazi persecution after 1943, as resistance, collaboration, and civil war raged. Many thousands of Italians—Jews and others—were deported to concentration camps throughout Europe. After the war, Italian culture produced a vast array of stories, images, and debate through which it came to terms with the Holocaust's difficult legacy. Gordon probes a rich range of cultural material as he paints a picture of this shared encounter with the darkest moment of twentieth-century history. His book explores aspects of Italian national identity and memory, offering a new model for analyzing the interactions between national and international images of the Holocaust.

A Jewish Heart: A Struggle for Status and Identity in Asia is at once the saga of a modest charitable grant in 1903, an unimagined windfall ninety years later, and a history of Progressive Judaism in Asia. Enriched with profiles of key players, the author rootsthe narratives in the entrepreneurial and philanthropic activities of two legendary Baghdadi families, the Sassoons and the Kadoories, beginning in mid-nineteenth century Bombay, Shanghai, and Hong Kong and unfolding against the backdrop of worldwide waves of Jewish arrivals. The story gains currency when challenges are raised over community funding, facilities, preserving or replacing the aging synagogue, and accommodating Reform Judaism. Robert L. Green provides a thorough and previously undocumented account of the decade-long religious, legal, and public relations battles that follow, engaging the attention of international media and top rabbinical and legal authorities in Hong Kong, Israel, Australia, United States, and United Kingdom. The author focuses on questionable legal gymnastics as trustees, facing China’s impending takeover of Hong Kong, undertake efforts to protect the funds from unknown perils. Concurrently, he chronicles the establishment of a vibrant Reform congregation, braided with Jewish lore, and the struggles of visionaries hoping to make Hong Kong an oasis of Jewish worship, learning, and recreation in Asia.
This book was first published in 2005. Copyright 'exceptions' or 'users' rights' have become a highly controversial aspect of copyright law. Most recently, Member States of the European Union have been forced to amend their systems of exceptions so as to comply with the Information Society Directive. Taking the newly amended UK legislation as a case study, this book examines why copyright exceptions are necessary and the forces that have shaped the present legislative regime in the UK. It seeks to further our understanding of the exceptions by combining detailed doctrinal analysis with insights gained from a range of other sources. The principal argument of the book is that the UK's current system of 'permitted acts' is much too restrictive and hence is in urgent need of reform, but that paradoxically the Information Society Directive points the way towards a much more satisfactory approach.
From the bestselling author of Disconnected Kids, a clear and compassionate explanation of the causes of the autism epidemic—and a scientifically based approach for prevention and treatment. As he travels the country helping parents and children cope with neurological disorders, Dr. Robert Melillo is always asked one question: Why? Why are autism rates exploding? But an equally important question always follows: What can we do about it as a society—and what can I do to help my child? In this candid, research-based, practical book, Dr. Melillo presents the latest scientific explanation for how we got here and proven, drug-free strategies that parents can employ to help prevent, detect, and address the autism epidemic for themselves and their families. With honesty and compassion, Dr. Melillo explains what the latest scientific research tells us about the role of genetic, environmental, and lifestyle factors, dispelling myths and replacing them with the facts. In addition, he presents early warning signs, a prevention plan for parents-to-be, and an intervention program for babies and young children.

Juxtaposes Antonio Gramsci’s work and critical race theory to offer a new understanding of tactics as a transformative practice. While scholars of social and political movements tend to analyze tactics in terms of their effectiveness in achieving specific outcomes, Robert F. Carley argues by contrast that tactics are, above all, what social movements do. They are not mere means to an end so much as they are a public form of expression pointing out injustices and making just demands. Rooted in a highly original analysis of the tactically mediated relationship between race and mobilization in the work of Italian philosopher and revolutionary Antonio Gramsci, Culture and Tactics demonstrates how tactics impact the organizational structures of social movements and expand the affinities of political communities. Carley looks at how Gramsci used innovative tactics to bridge perceptions of racial differences between factory workers and subaltern groups, the latter having been denigrated to the point of subhumanity by a complex Italian national racial economy. Newly envisioning Gramsci as a theorist of race within a broader context of social struggle, Carley connects Gramsci’s insights into the political mobilizations of racialized subaltern groups to contemporary critical race theory and cultural studies of racialization and racism. Speaking across disciplines and drawing on a number of empirical examples, Carleyoffers a battery of original concepts to assist scholars and activists in analyzing the tactical practices of protests in which race is a central factor. “This book provides an excellent rendering of Gramsci’s political perspective applied to race, and usefully extended to broader theoretical and practical applications.” — Lee Artz, coauthor of Cultural Hegemony in the United States
A meeting of great minds at the intersection of the arts and sciences “Enchanting. . . . The Poetic Species is a wonderful read in its entirety, short yet infinitely simulating.” —Maria Popova, Marginalian In this shimmering conversation, Edward O. Wilson, renowned scientist and proponent of “consilience” or the unity of knowledge, finds an ardent interlocutor in Robert Hass, whose credo as United States poet laureate was “imagination makes communities.” As they explore the many ways that poetry and science enhance each other, they travel from anthills to ancient Egypt and to the heights and depths of human potential.A testament to how science and the arts can join forces to educate and inspire, this book is also a passionate plea for conservation of all the planet’s species.

Misanthropoetics explores efforts by Renaissance writers to represent social flight and withdrawal as a fictional escape from the incongruous demands of culture. Through the invented term of its title, this book investigates the literary misanthrope in a number of key examples from Shakespeare, Jonson, Spenser, and the satirical milieu of Marston to exemplify the seemingly unresolvable paradoxes of social life. In Shakespeare’s England a burgeoning urban population and the codification of social controls drove a new imaginary of revolt and flight in the figure of the literary misanthrope. This figure of disillusionment became an experiment in protesting absurd social demands, pitting friendship and family against prudent economies, testimonies of durable love against erosions of historical time, and stable categories of gender against the breakdown and promiscuity of language. Misanthropoetics chronicles the period’s own excoriating critique of the illusion of resolution fostered within a social world beleaguered by myriad pressures and demands. This study interrogates form as a means not toward order but toward the impasse of irresolution, to detecting and declaring the social function of life as inherently incongruous. Robert Darcy applies questions of phenomenology and psychoanalysis, deconstruction and chaos theory to observe how the great deployers of literary form lost confidence that it could adhere to clear and stable rules of engagement, even as they tried desperately to shape and preserve it.
During the five full years of his presidency (1964–1968), Lyndon Johnson initiated a breathtaking array of domestic policies and programs, including such landmarks as the Civil Rights Act, Head Start, Food Stamps, Medicare and Medicaid, the Immigration Reform Act, the Water Quality Act, the Voting Rights Act, Social Security reform, and Fair Housing. These and other “Great Society” programs reformed the federal government, reshaped intergovernmental relations, extended the federal government’s role into new public policy arenas, and redefined federally protected rights of individuals to engage in the public sphere. Indeed, to a remarkable but largely unnoticed degree,Johnson’s domestic agenda continues to shape and influence current debates on major issues such as immigration, health care, higher education funding, voting rights, and clean water, even though many of his specific policies and programs have been modified or, in some cases, dismantled since his presidency. LBJ’s Neglected Legacy examines the domestic policy achievements of one of America’s most effective, albeit controversial, leaders. Leading contributors from the fields of history, public administration, economics, environmental engineering, sociology, and urban planning examine twelve of LBJ’s key domestic accomplishments in the areas of citizenship and immigration, social and economic policy, science and technology, and public management. Their findings illustrate the enduring legacy of Johnson’s determination and skill in taking advantage of overwhelming political support in the early years of his presidency to push through an extremely ambitious and innovative legislative agenda, and emphasize the extraordinary range and extent of LBJ’s influence on American public policy and administration.
Aside from the usual updating of material, the major change in this edition is an extensive rewriting of the chapter on memory and learning to emphasize that genes that are involved in behavior are not immutable but their expression can be modified by transcription factors. Thus, with respect to learning, that old question about which is more important, nature or nuture, genetics or environment, should be answered with the question, which leg is more important for walking, the left or the right?
Recently, the Research Triangle Institute completed a 5-year study sponsored by the National Institute on Drug Abuse called The Washington, D.C., Metropolitan Area Drug Study (DC MADS). Drug Use in Metropolitan America describes, relates, and integrates findings from the DC MADS study. More than that, though, this book places the findings in the larger context of our national drug abuse problem. Therefore, while there is some reporting of findings, there is more emphasis on examining the policy, research, and program implications that flow from the studies. This book will be of interest to researchers, practitioners, and policymakers in a number of areas, as well as to academics in sociology courses dealing with drugs, deviance, social problems, and research methodology. It should also appeal to those in the psychology and medical/allied health fields.
The gold standard reference for all those who work with people with mental illness, Kaplan & Sadock's Comprehensive Textbook of Psychiatry, edited by Drs. Robert Boland and Marcia L. Verduin, has consistently kept pace with the rapid growth of research and knowledge in neural science, as well as biological and psychological science. This two-volume eleventh edition offers the expertise of more than 600 renowned contributors who cover the full range of psychiatry and mental health, including neural science, genetics, neuropsychiatry, psychopharmacology, and other key areas.
Each year, millions of people are internally displaced and resettled in the wake of wars and floods or to make way for large-scale development projects, and this number is increasing. Humanitarian and development specialists continue to struggle with designing and executing effective protection strategies and durable solutions. Relocation Failures explains how internal displacement and efforts to engineer resettlement are conceived and practiced by policy makers and practitioners. The author argues that policies for internally displaced peoples are weak and diluted by narrow interpretations of state sovereignty and collective action dilemmas, and in the case of Sri Lanka, unintentionally intensified ethnic segregation and ultimately war. This unique new book considers the origins and parameters of internal displacement and resettlement policy and practice and proposes an explanation for why it often fails. In highlighting the ways that development assistance can exacerbate smoldering conflicts, the volume provides an important caution to the aid community.
Next to air, water is the most essential of human requirements. The hydrosphere-the waters of the Earth, its oceans, rivers and lakes-is vital, constituting a feature unique in the solar system and one responsible for physical and climatic phenomena characteristic of the planet. Water moves through the hydrologic cycle and runs the heat engine of the Earth, approximately 97% of it occurring in the oceans. These contain vast natural resources including abundant plant and animal life and they assist in cleansing the atmosphere by becoming the final repository of air and land pollutants of which many are man-made. Unfortunately their ability to do this is diminishing because of rising pollution by toxicants such as DDT, nuclear by-products such as strontium-90 and oil spills. The oceans contain huge quantities of various substances mostly originating from the atmosphere, biological activity, river transport after rock weathering, groundwater, spreading zones along mid-oceanic ridges and crustal out-gassing. After hydrogen and oxygen, the commonest elements in them are Cl, Na, Mg, S, K, Ca, Br, C and B. The atmosphere and the oceans together cooperate in an energy cycle important in controlling and equalising the Earth's surface temperature.
