Four years ago, I was kidnapped, taken to an isolated sugarcanefield, and raped by a gang of three men. My intention in sharingthis information is not to make you feel sorry for me in a condescendingattitude that would only undermine the seriousness of such adevastating experience rather, I would like to change your wayof feeling and thinking about what that experience representsfor a woman. If ever you are forced to confront a person whohas survived such aggression, this may help you to understandwhat she has gone through and what still awaits her 相似文献

This essay synthesizes the history of the birth control movement in the US and describes changes in sexual behavior, social values, and public policy in order to provide a context for the changes in human reproductive public policy. After an introduction, the essay outlines the history of contraception from the early nineteenth to the early twentieth centuries. Part 3 covers the period of World War I to the Depression when civil libertarians and eugenicists began to question the suppression of contraception and Margaret Sanger organized her clinics. The fourth part of the essay carries the history forward to the end of World War II, a period in which Dr. Clarence J. Gamble began to expose the marketing of defective contraceptive methods and to illustrate the willingness of poor women to accept contraceptives. The social changes which began in the 1950s are the subject of the fifth section of the essay. During this period, Roman Catholic opposition to contraception lessened, and social scientists began to focus world attention on overpopulation. Frank Notestein was appointed the first head of the Office of Population Research at Princeton, and John D. Rockefeller III founded the Population Council which conducted research into the IUD and began to attempt to influence population growth in nonindustrialized countries. This period also saw the development of the oral contraceptive. The changes of this era were institutionalized in 1967 when the federal government took a positive stance towards family planning in its Social Security Amendments. The decade of the 1970s is the subject of the last part of this essay. This period saw the Supreme Court assign a constitutionally protected right to abortion and Congress pass the Helms Amendment which denied the use of foreign aid funds for abortions. Challenges to the right to individual birth control practice continued during this period, and debate centered around the specter of overpopulation, the threat of adolescent pregnancy, and perceptions of "family values." 相似文献

Telepresence-enabled exploration of deep sea environments has developed over the past 30 years, providing access to archaeologists, scientists, and the general public to sites otherwise inaccessible due to depth. Pioneered through the inception of the JASON Project in the late 1980 s, telepresence missions have expanded to two dedicated ships of exploration, NOAA Ship Okeanos Explorer and exploration vessel Nautilus, and has been implemented on a series of opportunistic missions on other vessels. This paper chronicles the history of the use of telepresence for the exploration of shipwrecks in deep water as well as how this capability has allowed the public to engage with such missions. Broadening the scope of who can explore the deep sea, telepresence has also expanded what is observed and documented in the deep, which speaks to humanity’s use of the maritime world and an archaeology of discard through our material disposed of into the deep sea. 相似文献

During late winter and spring, hunter-gatherers in temperate, subarctic, and arctic environments often relied on diets that provided marginal or inadequate caloric intakes. During such periods, particularly when stored food supplies dwindled or were used up entirely, lean meat became the principal source of energy. Nutritional problems associated with high-protein, low-energy diets are discussed. These problems include elevated metabolic rates, with correspondingly higher caloric requirements, and deficiencies in essential fatty acids. The relative benefits of adding fat or carbohydrate to a diet of lean meat are evaluated in light of the protein-sparing capacities of these two nutrients. Experimental data indicate that although both enhance high-protein, low-energy diets, carbohydrate is a more effective supplement than fat. Given the nutritional inadequacies of a lean-meat diet, the paper concludes with a discussion of alternative subsistence strategies that increase the availability of carbohydrate or fat at the critical time of year. 相似文献

Based on two years of participatory video drama (PVD) research with men and women in the city of Hu?, this article explores perspectives on, and experiences of, socio-economic transition and its influence on domestic life in Vietnam. Through a combination of output analysis, group screening sessions and individual interviews, it concentrates on the themes of marriage, parenting and ‘social evils’ which emerged in the PVD. It demonstrates how familial tensions collectively identified in the workshop and told in a single video-narrative are complicated by the more nuanced discourses that emerge from co-produced analysis in the post-production period. These illuminate a greater plurality of voices towards the liberalisation of the Vietnamese economy and the new life choices that this brings. 相似文献

Drawing on three select case studies and feminist engagements with mobility studies, I illustrate the Irish state’s use of a dialectic of gendered and racialized citizenship, and mobility and fixity, in the creation of ‘new geographies of belonging and exclusion’. Using detailed analyses from select cases, I argue for more nuanced feminist engagements with mobility that acknowledge and analyse ‘processes and trajectories’ in relation to a geopolitics of abortion – one that eschews undifferentiated uses of the category migrant and discourses of tourism, in analysing abortion in the Republic of Ireland. I expose how their use constructs limited ideas about gender, nation and Irishness to assure exclusions from Ireland, and from its diaspora. 相似文献
