The Path to Gay Rights: How Activism and Coming Out Changed Public Opinion
by Jeremiah J. GarretsonAn innovative, data-driven explanation of how public opinion shifted on LGBTQ rights The Path to Gay Rights is the first social science analysis of how and why the LGBTQ movement achieved its most unexpected victory—transforming gay people from a despised group of social deviants into a minority worthy of rights and protections in the eyes of most Americans. The book weaves together a narrative of LGBTQ history with new findings from the field of political psychology to provide an understanding of how social movements affect mass attitudes in the United States and globally. Using data going back to the 1970s, the book argues that the current understanding of how social movements change mass opinion—through sympathetic media coverage and endorsements from political leaders—cannot provide an adequate explanation for the phenomenal success of the LGBTQ movement at changing the public’s views. In The Path to Gay Rights, Jeremiah Garretson argues that the LGBTQ community’s response to the AIDS crisis was a turning point for public support of gay rights. ACT-UP and related AIDS organizations strategically targeted political and media leaders, normalizing news coverage of LGBTQ issues and AIDS and signaled to LGBTQ people across the United States that their lives were valued. The net result was an increase in the number of LGBTQ people who came out and lived their lives openly, and with increased contact with gay people, public attitudes began to warm and change. Garretson goes beyond the story of LGBTQ rights to develop an evidence-based argument for how social movements can alter mass opinion on any contentious topic.

Heavenly Sex: Sexuality and the Jewish Tradition
by Dr. Ruth Westheimer Jonathan MarkCelebrated sex expert and bestselling author Dr. Ruth Westheimer bridges the gap between sex and religion in this provocative exploration of intimacy in the Jewish faithIn this light-hearted, lively tour of Jewish sexuality, Dr. Ruth K. Westheimer and Jonathan Mark team up to reveal how the Jewish tradition is much more progressive than popular wisdom might lead one to believe.Applying Dr. Ruth’s acclaimed brand of couples therapy to such Biblical relationships as Abraham and Sarah, and Joseph and Potiphar’s wife, the authors enlist Biblical lore to explore such topics as surrogacy, incest, and arranged marriages. They offer a clearer understanding of the intertwining relationships between sexuality and spirituality through incisive investigations of the Song of Songs, Ruth, Proverbs, Psalms, and some of the bawdier tales of the Prophets. One chapter provides a provocative new perspective on the Sabbath as a weekly revival, highlighting not only its spiritual nature, but also its marital and sexual aspects.Focusing specifically on Orthodox forms of Judaism and offering Dr. Ruth's singular interpretations, the book answers such questions as: What night of the week is best for making love? How often should couples have sex? Can traditional Jewish notions of sex and sexuality be reconciled with contemporary beliefs? What roles can and do dreams and fantasy play?In Heavenly Sex, America's favorite sex therapist takes readers on a frank and fascinating journey to the heart of Jewish sexuality as she fits twenty-first century sexual mores into an ancient—and lusty—spiritual tradition.

Inequality, Democracy, and the Environment
by Liam DowneyWinner, American Sociological Association Section on Environment and Technology Allan Schnaiberg Outstanding Publication AwardThe world currently faces several severe social and environmental crises, including economic under-development, widespread poverty and hunger, lack of safe drinking water for one-sixth of the world’s population, deforestation, rapidly increasing levels of pollution and waste, dramatic declines in soil fertility and biodiversity, and global warming. Inequality, Democracy, and the Environment sheds light on the structural causes of these and other social and environmental crises, highlighting in particular the key role that elite-controlled organizations, institutions, and networks play in creating these crises. Liam Downey focuses on four topics—globalization, agriculture, mining, and U.S. energy and military policy—to show how organizational and institutional inequality and elite-controlled organizational networks produce environmental degradation and social harm. He focuses on key institutions like the World Bank, the International Monetary Fund, the U.S. Military and the World Trade Organization to show how specific policies are conceived and enacted in order to further elite goals. Ultimately, Downey lays out a path for environmental social scientists and environmentalists to better understand and help solve the world’s myriad social and environmental crises. Inequality, Democracy and the Environment presents a passionate exposé of the true role inequality, undemocratic institutions and organizational power play in harming people and the environment.
The Filipino Primitive: Accumulation and Resistance in the American Museum
by Sarita Echavez SeeHow museums’ visual culture contributes to knowledge accumulationSarita See argues that collections of stolen artifacts form the foundation of American knowledge production. Nowhere can we appreciate more easily the triple forces of knowledge accumulation—capitalist, colonial, and racial—than in the imperial museum, where the objects of accumulation remain materially, visibly preserved. The Filipino Primitive takes Karl Marx’s concept of “primitive accumulation,” usually conceived of as an economic process for the acquisition of land and the extraction of labor, and argues that we also must understand it as a project of knowledge accumulation.Taking us through the Philippine collections at the University of Michigan Natural History Museum and the Frank Murphy Memorial Museum, also in Michigan, See reveals these exhibits as both allegory and real case of the primitive accumulation that subtends imperial American knowledge, just as the extraction of Filipino labor contributes to American capitalist colonialism. With this understanding of the Filipino foundations of the American drive toward power and knowledge, we can appreciate the value of Filipino American cultural producers like Carlos Bulosan, Stephanie Syjuco, and Ma-Yi Theater Company who have created incisive parodies of this accumulative epistemology, even as they articulate powerful alternative, anti-accumulative social ecologies.

A Search for Origins: Science, history and South Africa's 'Cradle of Humankind'
by Philip Bonner,Amanda Esterhuysen & Trefor JenkinsA study of the 'Cradle of Humanity and its history.The 'Cradle of Humankind' (COH), bordering Gauteng and the North-West Province, was declared a World Heritage Site for the wealth of the human and animal fossils found there. Research based on fossils found in the area as well as signs of early human habitation have shed new light on the evolution of humankind and on the significant role that southern Africa played in the development of modern humans. A Search for Origins aims to provide an overview of the history of the COH, and of the important discoveries that have been made there, for a non-specialist audience. A number of general accounts have been written which have concentrated on the palaeontological discoveries made there. No systematic account written by specialists in their disciplines has, however, been published about the wider history of the COH and surrounding areas. In particular, no overview spanning the evolution of early plant and animal life, human development and recent and colonial history as reflected in discoveries linked to the COH, has been attempted. This edited volume frames the scientific advances that have been made in the COH against the intellectual and political background out of which they emerged. The multi-disciplinary approach - from a wide range of specialists -is innovative and ground-breaking.
Good Intentions in Global Health: Medical Missions, Emotion, and Health Care across Borders (Anthropologies of American Medicine: Culture, Power, and Practice)
by Nicole S. BerryExplores informal global health action and the importance of intentions of those who volunteerIn the past two decades, medical missions have gained popularity among medical professionals, who view these excursions as important ethical interventions. Indeed, the notion of giving back by volunteering in rural or impoverished communities is celebrated as an ideal act of selflessness, one whose effects are unquestionably beneficial to those being served.Good Intentions in Global Health is a groundbreaking exploration of the growing realm of informal global health engagement, shedding light on the intricate interplay between intentions, emotions, and ethical considerations. Drawing on fieldwork in Guatemala, Nicole S. Berry investigates those who volunteer for short-term medical missions, revealing how the intent to do good shapes their everyday understandings of their own actions taken in the global health domain.Berry uncovers how the glorification of medical missions can obscure problems that stem from North American clinicians doctoring in places where they typically do not understand the context. The short-term nature of missions also means that volunteers are not privy to the long-term effects of their actions—the potential harms that may arise from a lack of sustained follow-up care or the utter absence of documentation that they were even there. By relying on gut instincts to reassure themselves that they are doing good, volunteers often bypass a comprehensive assessment of the ethical dimensions underlying their global health work.Good Intentions in Global Health shows why desires and emotions are increasingly important to contemporary global health. She makes the case that we must pay attention to volunteers’ perceptions of their work, however wrongheaded or naïve, in order to truly influence global health on the ground.
