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

Katherine Side 《Gender, place and culture : a journal of feminist geography》2016,23(12):1788-1799
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

In George Orwell’s 1984, the poet Ampleforth observes that “the whole history of English poetry has been determined by the fact that the English language lacks rhymes.” In this article I connect Ampleforth’s observation to Orwell’s many other writings on language and political control and then show how Orwell’s discussion of poetry’s resistance to political manipulation enhances Tocqueville’s and Burke’s accounts of totalitarianism. Specifically, Orwell illustrates how an easily “rhyming” polity is particularly vulnerable to totalitarian politics, while a society containing considerable disorder in its language and politics can be strongly resistant to such tyranny. 相似文献

The Swiss Cantons had no greater admirer in the eighteenth-century than the French political thinker Gabriel Bonnot de Mably. The feeling was mutual, at least to some extent, since the Bernese Patriotic Society awarded its first prize in 1763 to Mably, for his dialogue Entretiens de Phocion. The prize then led to an exchange of letters, stretching across some two decades, with Daniel Fellenberg, founder of the Patriotic society—the most important block of Mably's correspondence to have survived. This essay considers the 1763 prize and the correspondence with Fellenberg for the light they cast both on Mably and on Bernese participation in the wider currents of eighteenth-century thought. 相似文献

The interpretation that a rock has been subjected to cultural utilization is a basic element of hunter-gatherer research. The fracture mechanics of the flaked stone tool production process are well understood and the material residues are routinely identified during fieldwork. Conversely, non-percussion processes such as hot-rock technology, which can result in rock fracture, are less well understood. An experimental study has been developed to examine the fractured gravels observed at a prehistoric site on the Southern Plains (USA). The experiment has sought to determine whether cultural or natural agencies were responsible for the production of the angularly fractured rocks. The positive results of the experiment indicate that not only were humans most likely responsible for the breakages, but also that the fractured rocks often exhibit distinctive morphologies that may be identified during fieldwork. This simple experimental methodology is applicable to other hunter-gatherer sites where the depositional environment is not conducive to the structural preservation of features such as hearths. 相似文献
