Macrofracture analysis is an experimentally derived method used as an initial step in investigating the hunting function of stone artefacts. Diagnostic impact fractures, which can only develop as a result of longitudinal impact, underpin this method. Macrofracture analysis recently gained favour in Middle Stone Age studies, supporting hypotheses for effective hunting during the late Pleistocene in southern Africa. However, the factors affecting diagnostic impact fracture formation and the interpretation of these fracture frequencies are not yet fully understood. This paper outlines a set of experiments designed to test macrofracture formation under human and cattle trampling and knapping conditions. The results show that: (a) macrofractures occur frequently when stone artefacts are trampled by cattle and humans and in knapping debris; (b) diagnostic impact fractures occur on some of the trampled flakes and knapping debris (≤3%), but significantly less often than in previous hunting experiments; (c) when they do occur, they are likely produced by longitudinal forces similar to those experienced during hunting; (d) considering artefact morphology is important during macrofracture analysis; and (e) macrofracture analysis is not a standalone method, but is most useful as part of a multi-analytical approach to functional analysis. These experiments help to establish a significant baseline diagnostic impact fracture frequency for the interpretation of archaeological macrofracture frequencies. 相似文献

Recent syntheses for the Long Island Sound region argue for long-term cultural continuity amongst Holocene coastal hunter-gatherers. These notions derive primarily from studies of quartz lithic assemblages, which archaeologists argue show structural stasis over time. The remaining variability is explained with a ‘distance to source' model in which near-coastal sites tend to show a lack of quartz conservation while interior sites show quartz recycling. Under this model, technological strategies traditionally associated with raw material conservation (e.g., bipolar reduction) should not occur at near-coastal sites. We test the ‘distance to source’ model by reexamining a quartz lithic assemblage from Eagle's Nest-Long Island's richest Holocene coastal hunter-gatherer site. We find conclusive evidence for bipolar reduction in the site's “block/shatter” materials. Toolmakers used bipolar reduction to conserve raw material. Toolmakers also used anvils and bipolar reduction to open quartz cobbles, to stabilize freehand cores, to efficiently access cutting edges, and possibly to create crushed coarse quartz temper for pottery production. Our results point to previously unrecognized aspects of behavioral variability in the Eagle's Nest lithic assemblage and to possible revision of the ‘distance to source’ model. Similar variability may be present at other North American sites with quartz “block/shatter” material. 相似文献

Recent archaeological studies reveal a growing interest in the relationship between local coastal dynamics and broader currents of Mediterranean seaborne connectivity. Using as a case study the complex harbour site of Burgaz and its maritime landscape of the Datça peninsula in southwest Turkey, this paper considers trajectories of port development in communities that are pre-modern and pre-industrial but increasingly interconnected and interdependent. While the peninsula’s fertile low-lying farmlands made Archaic and early Classical Burgaz an economic backbone and centre of regional exchange in the southeast Aegean, the growth of eastern Mediterranean networks of the late Classical and Hellenistic era eventually favoured Knidos as the better situated hub for maritime activity. Building on the influential “Anyport Model” by geographer James Bird (1963, 1971), this article explores patterns of coastal development at Burgaz as a reflection of local responses to intersecting political, economic and environmental factors. By contextualizing the long-term evolution of one dynamic landscape, the model aims to shed light on how ancient Mediterranean port communities negotiated a constantly shifting place within complex and evolving maritime networks. 相似文献

AbstractChurchill's lifelong meditation on scientific progress led him to search for ways in which its transformative power could be moderated and guided for the preservation of civilization. The increasing role of scientific discovery and technological innovation in maximizing the destructive potential of warfare, Churchill believed, had brought a moment of decision for humanity: Whether to foster and maintain the moral and political principles that formed the foundation of civilized life or to trust wholly in an amoral science. He found guidance in the study of the humanities, Anglo-American constitutionalism, and Christian ethics. 相似文献

In December 1953 Sukumar Sen, an Indian civil servant, bid farewell to Sudan, having just overseen Sudan's ‘self-government’ election. ‘Your election’, he told the people of Sudan in a radio broadcast, ‘can legitimately claim to have been a model of its kind.’ The election had seen determined attempts at manipulation—by Sudanese and by Sudan's rival colonial masters, Egypt and Britain. Much of this manipulation revolved around the mechanics of the election, and there were bitter arguments within the Electoral Commission which oversaw the event. Yet all involved were driven by a concern over representation—over how the election would look, to outsiders and to those involved. This paper will examine the debates over how the election should be conducted, and will suggest that, for those who organised it, the election was concerned not so much with representation of the will of the people, but rather with the representation of process. 相似文献
