The relationship between tool form and function is fundamental to hominin behaviour and evolution. Acheulean handaxes are known for their general consistency across more than a million years and three continents, albeit with some variation in size and shape. However, the influence of this variation on cutting has only rarely been studied, mostly in either butchery or generalized cutting tasks. Yet evidence indicates that handaxes were used for woodworking by at least 1.5 mya. Here, we experimentally tested whether woodworking could have exerted selective pressures on handaxe form. Additionally, these data were compared with a previous experiment that tested flakes during woodworking. For handaxes, no significant relationships were detected in woodworking efficiency. Accordingly, woodworking likely did not exert strong selective pressures on handaxe variability. However, the effectiveness shown by handaxes further demonstrates the functional flexibility of this technology, which is likely a factor contributing to their use over broad temporal, geographical and ecological spans. When comparing handaxes with flakes, only the smallest flakes were found to be significantly less efficient than handaxes. Therefore, the functional demands of woodworking were likely influencing hominin technological decisions about flake morphology, or the selection of flakes for woodworking, more than they were handaxe morphology. 相似文献

This paper examines the historiography of ancient town planning and the Roman city, with particular attention to its origin in the town planning debate of the early twentieth century. It questions the existing dichotomies, ‘civilised'/'uncivilised’, ‘classical'/'barbarian’, ‘urban'/'proto‐urban’, that have characterised this history. Finally, the paper examines the effect of the separation of the academic disciplines of classics and archaeology in Britain upon the history of ancient urbanism. 相似文献

This article analyzes a selection of travel accounts by nine British authors who journeyed across Canada between 1900 and 1914. The monographs, all published in London, purported to present authentic and up-to-date observations of Canada, the eldest Dominion in the Imperial “family,” to British and Canadian audiences. Additional goals of their narratives, and less clearly acknowledged, were to convince English Canadians of the value of strengthening a British–Canadian identity and remaining within the British Empire. To that end, the narratives explore strikingly similar themes, including anxieties surrounding immigration and the United States threat to Canada, while reinforcing notions of Empire as an indissoluble family. The article illustrates how travel narratives reflect psychological as well as physical journeys and are thus valuable windows on complex cultural encounters among the British and Canadians in this period. 相似文献

While scholars have considered the various meanings of roller derby for participants and discussed how roller derby critiques and stabilizes gender and sexuality normativity, their investigation into how a larger public is impacted by roller derby's public performances has received less attention. Here, we begin to address this oversight. Employing both participant and spectator data, we examine facets of publicness in the discursive and material spatial practices associated with roller derby in the US Bible Belt, specifically Oklahoma. While some scholars doubt that there is much social impact from roller derby, we suggest that the specific spatial qualities in roller derby's public performances, in both the sporting and playful senses, contribute to a change in cultural norms – that of greater recognition of diverse genders and sexualities in this region. Such validation increases the social stability of individuals who do not neatly reside within heteronormativity. 相似文献
