It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

It is a feature of the twenty-first century that world languages are displacing local languages at an alarming rate, transforming social relations and complicating cultural transmission in the process. This language shift—the gradual abandonment of minority languages in favor of national or international languages—is often in response to inequalities in power, signaling a pressure to conform to the political and economic structures represented by the newly dominant languages. In its most extreme form, language shift can result in language death and thus the permanent loss of traditional knowledge and lifeways. To combat this, indigenous and scholarly communities around the world have undertaken various efforts, from archiving and lexicography to the creation of educational and cultural programs. What works in one community, however, may not work in another. Indeed, while the causes of language endangerment may be familiar, the responses to it depend on “highly specific local conditions and opportunities.” In keeping with this premise, the editors of this volume insist that to understand language endangerment, “researchers and communities must come to understand what is happening to the speakers, not just what is happening to the language.” The eleven case studies assembled here strive to fill a gap in the study of endangered languages by providing much-needed sociohistorical and ethnographic context and thus connecting specific language phenomena to larger national and international issues. The goal is to provide theoretical and methodological tools for researchers and organizers to best address the specific needs of communities facing language endangerment. The case studies here span regions as diverse as Kenya, Siberia, Papua New Guinea, Mexico, Venezuela, the United States, and Germany. The volume includes a foreword by linguistic anthropologist Jane Hill and an afterword by poet and linguist Ofelia Zepeda.
