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

One purpose of the Advocacy Coalition Framework (ACF) is to explain policy change. Previous holistic reviews of the ACF by Weible, Sabatier, and McQueen (2009) and Pierce, Peterson, Jones, Garrard, and Vu (2017) of the framework have not explicitly analyzed all the concepts and their interactions in a systematic manner. To address this gap and inform scholars and practitioners about past findings, strengths, weaknesses, and opportunities for future research, this article analyzes how the ACF's theory of policy change is applied to 148 policy processes among 67 journal articles from 2007 to 2014. Similar to Weible et al. (2009), this research finds the frequent use of multiple primary pathways to policy change, infrequent use of many of the ACF's concepts, a plurality of applications in the environment and energy domain, comparison of subsystems, and a need for greater clarity and transparency among applications. Unlike Weible et al. (2009), this article explores associations between primary pathways and policy domains, the frequency of associations between primary pathways and secondary components, policy change and stasis, and identifies threats to internal validity of key ACF concepts.  相似文献

Noel Pearson is one of Australia's most prominent and influential Indigenous intellectuals. This article examines a major idea in Pearson's writing, the ‘quest for a radical centre’. It examines this idea from the perspective of both its usefulness in understanding the deficiencies in public conversation about Indigenous affairs, and its persuasiveness in legitimating the role that Pearson has played nationally as a champion of the Indigenous responsibility discourse. The article argues that conceptualising public debate as a quest for a radical centre resonates strongly with the theory of deliberative democracy. Similar to Dryzek and Niemeyer's work on ‘discursive representation’, the idea of the radical centre reveals the legitimacy possessed by unelected champions of discourses.

诺艾尔·皮尔森是澳大利亚最杰出的原住民知识分子。本文考察了皮尔森写作的一个主要思想,“探索激进的中心”。在作者看来,这思想有助于理解有关土著事务的公共对话的缺陷,它还让皮尔森在全国扮演的角色——土著人责任话语的捍卫者——富于说服力。将公共辩论理解为对激进中心的探索,这与商议民主的理论非常合拍。与德雷泽克和尼美耶论“话语代表性”的著作相类,激进中心的思想指出了未被选择的话语卫士的合理性。  相似文献
