AbstractThe prehistoric development of food storage represents a major evolutionary transition, one potentially more important than the initial domestication of plants. Researchers, however, have yet to really deal with some of the critical practical questions related to the materiality of food storage and decision-making. Drawing upon experimental research this paper seeks to identify and model some of the critical interconnections between anticipated food loss due to spoilage, storage decision-making and the need for people to store food for multiple years. Building on this foundation, and echoing ethnographic, ethnoarchaeological and archaeological research, this study argues that the concept of storage and surplus is underdeveloped and that in many cases the storage practices of prehistoric sedentary people do not reflect a food surplus so much as normal storage. Turning to a case study of changing Near Eastern Neolithic grain storage practices, this research argues that from the Natufian through Neolithic periods people increasingly relied upon cultivated domesticated plants and food storage. This required people to expand their use of pre-existing technology, such as plaster for lining storage features, to store sufficient amounts of food to overcome seasonal shortages, potential crop failures and minimise food spoilage due to a range of biological agents. Tracking shifts through time, the results of this study suggest that it is only with increased scale of food storage in the later stages of the Neolithic that we may see a materialization of a food surplus. 相似文献

一场甲午战争,使东亚海权格局剧变,由此构成中日两国命运变化的历史拐点。战前,中日两国面对西方殖民扩张的相同遭遇,展开了近30年的海军现代化建设,并在互为敌手的竞争中日益凸显于以英国为主导的东亚海权格局之中。然而,不同的战略选择决定了不同的命运,甲午战争用血与火诠释了海权与海防的本质区别及其决定性影响。正因为战败后的中国已完全置身于东亚海权格局之外,再次陷入有海无防的境地,导致海权得以坐大的日本推行"大陆政策"更加有恃无恐,在列强瓜分中国的狂潮中走上独霸东亚之路。 相似文献

Pursuing Urban Commons: Politics and Alliances in Community Land Trust Activism in East London 总被引:1,自引:0,他引:1 下载免费PDF全文
Susannah Bunce 《对极》2016,48(1):134-150
Community land trust (CLT) practices contribute to analyses of the commons in both conceptual and on‐the‐ground ways. As collective action organizations, CLTs emphasize common land stewardship and resist traditional land speculation and development practices through the mitigation or halting of land value inflation. This paper traces the activist efforts of the East London CLT organization, one of Britain's first urban CLTs, in securing common land in the East London borough of Tower Hamlets, and examines their navigation of political decisions and creation of alliances. Although this process has been challenging as a result of neoliberal governance and private development interests, the East London CLT's trajectory demonstrates the frustrations of activism within these contexts but also the small successes in the pursuit and establishment of urban commons. 相似文献

AbstractIn September 1899, at the annual meeting of the British Association for the Advancement of Science (BAAS) in Dover, Guglielmo Marconi’s wireless telegraphy system was used to transmit messages across the English Channel (and across a national border) for the first time. This achievement represented a highly effective performance of scientific masculinity and constitutes a key turning point in an important struggle between competing interpretations of invention and innovation as masculine practices within British science. The British Association tended to favor a narrative of scientific research as a collectivist, international, gentlemanly-amateur pursuit, largely confined to the laboratory. Marconi, by contrast, explained the development of wireless telegraphy as the achievement of his own genius. Appealing not only to the established scientific elite but to a range of non-traditional audiences, and stressing the possibilities or ‘imagined uses’ of his technology even more so than his actual results, he succeeded in commanding unprecedented influence. 相似文献

Both Canada and the United States have “pivoted” toward Asia in their foreign policy over the past decade, although emphases in those pivots differed between the two countries. The former focuses on an economic pivot initially, the latter on a security one. What factors explain these shifts? What was the magnitude of policy change by both? Utilizing some important theoretical works by Charles Hermann, we discuss the factors that appear to have brought about this policy change toward Asia, outline the actions and activities that both countries have initiated toward Asia in the past decade to illustrate the type and magnitude of policy change that has occurred, and compare some areas of political, economic, and military similarities between Canada and the United States toward this region. Finally, we assess the likely future of these pivots to Asia in light of the change in political leadership within both nations. 相似文献

Constructivism in most of its variants emphasises the creation of circumstances and the social construction of reality. In international relations theory (IR), it also emphasises the establishment of international regimes. The Suez Canal and its governing regime, established at a high point of European nationalism and imperialism in the nineteenth century, are explored as a test case. I argue that, while the early history of the Canal is illuminated by a constructivist approach, maintenance of the regime to govern it involved military intervention and debt restructuring. Military force, balance of power considerations and economic interests all have to be invoked to explain the later history of the Canal, that is, factors usually stressed by the realist school. A combination of realist and constructivist approaches is recommended. The paper is also critical of certain constructivist concepts of national identity. 相似文献

Jerash in northern Jordan was, despite a focus on its classical heritage, also active in the Middle Islamic period, but little is known about actual developments during this period. This study represents the first study on the Middle Islamic glazed pottery from the site using scanning electron microscopy energy‐dispersive spectrometry (SEM‐EDS) and thin‐section petrography. The results show that two production traditions existed, each with different provenances. The local production is characterized by a non‐calcareous ceramic body and the use of a high‐lead glaze coloured with iron and copper oxides, whereas the turquoise‐glazed samples, likely imported from Mesopotamia, have a calcareous ceramic body and alkali or alkali‐lead glaze. 相似文献

AbstractThis article discusses the issue of the Ming army's maritime shipping of supplies during the second stage of the East Asian War of 1597–8. Despite the lack of historical sources and difficulty in finding accurate numbers, Zhang Yangmeng's 張養蒙 memorials include records of maritime transport decisions, implementation, effectiveness, and limitations and are of great help to filling in the blank areas of research in Ming army logistics. 相似文献

AbstractDuring the second stage of the East Asian War, Toyotomi Hideyoshi 豐臣秀吉 hopefully sought to make an honorable exit, but the Choson 朝鮮 formulated a unique diplomatic strategy that brought the Ming to the battlefield, and there was no way for Toyotomi Hideyoshi's retreat and attempts at peace talks to be successful. In the end, the war concluded with Toyotomi Hideyoshi's death from illness and the retreat of the Japanese army in defeat, and the international order established between China and Korea was maintained. 相似文献
