A sample of 82 anterior teeth from Krapina (Croatia) was studied using a light binocular microscope and a scanning electron microscope to document the presence of non-dietary dental scratches. The patterns of distribution, location and orientation of these marks suggest two different aetiologies: scratches on the labial-occlusal enamel border appear to be related to the action of clenching abrasive materials between teeth, while the scratches primarily in the centre of the labial face correspond to cutmarks as described by other researchers. These scratches may have been produced when flake tools involved in processing materials held between the anterior teeth came into contact with the labial enamel face. Alternatively, they may simply reflect some consistent operation which pulled hard objects across the labial surfaces of the anterior teeth. In either case, the marks on the central face of the labial surface provide evidence for manual dexterity in the Neanderthals. Of the seven Krapina individuals which show a predominant pattern, one shows a pattern of left oblique marks, while six provide evidence of right-handedness. Coupled with other Neanderthal or Upper Pleistocene individuals with these patterns, right-handedness is the dominant pattern in 90 per cent of the documented cases. One complicating factor in the analysis of these scratches in the Krapina hominids is that marks of a similar morphology are found in several anterior teeth of Ursus spelaeus from the site. While resembling the marks on the hominid incisors, the scratches on the bears lack a dominant orientation on the labial face and appear to be more variable in their widths. Despite the occurrence of some similarities in the enamel scratches between ursids and hominids at Krapina, the study of anterior dental marks provides information about manipulative activities which are unique to ancient humans. © 1997 by John Wiley & Sons, Ltd.

The early nineteenth century was transformative of the Supreme Court's practices. Yet understanding those fundamental changes requires some appreciation of practice before the Court in the late eighteenth century, and the developments in the early nineteenth century produced changes in the Court's practices that are still felt today. In this first half-century or so of the Court's existence, more dramatic developments and changes occurred in oral argument practice than in any other period of the Court's history. 1 相似文献

One of the paradoxical effects of the 7 July bombings in London was to expose the ambivalence in the British government's attempt to wage war on terror by forcefully prosecuting war against those who resort to jihad abroad, actively participating in coalitions of the willing whether in Afghanistan or Iraq, while affording some of Islamism's key ideologists and strategists a high degree of latitude in the United Kingdom itself. This indicates a number of contradictions in official policy that simultaneously recognizes the globalized threat from violent Islamic militancy while, under the rubric of multiculturalism, tolerating those very strains of Islamist radicalism, some of which draw upon the interdependent and transnational character of conflict, to render the UK vulnerable to those very same violent forces. Consequently, the British authorities displayed a studied indifference towards this developing transnational phenomenon both during the 1990s and in some respects even after the London bombings. To explore the curious character of the government's response to the Islamist threat requires the examination of the emergence of this radical ideological understanding and what it entails as a reaction to modernization and secularism in both thought and practice. The analysis explores how government policies often facilitated the non-negotiable identity politics of those promoting a pure, authentic and regenerated Islamic order both in the UK and abroad. This reflected a profound misunderstanding of the growing source and appeal of radical Islam that can be interpreted as a consequence of the slow-motion collision between modernity in its recent globalized form and an Islamic social character, which renders standard western modernization theory, and indeed, the notion of a 'social science' itself, deeply questionable. 相似文献

Alfred Marshall believed that, while the benefits of clusters resulted from cooperation between firms, competition was an important driving force. In contrast, contemporary theories of clusters place most emphasis on collective action. This article seeks to distinguish processes of competition and cooperation within clusters, through a critical reading of different theoretical approaches. This distinction has important implications for the scale and nature of public policy. An emphasis on competitive processes implies a more macro-economic role for public agencies in seeking to raise investment in innovation while the fostering of cooperation implies measures to support decentralized public-private research collaborations. 相似文献

Much has been made of completing the Single European Market in Europe. Despite movements towards more advanced levels of integration such as currency union, there remains several grey areas in specific industries that are not allowing for open access to the market. These areas include government activities such as electricity and gas along with other industries such as telecommunications. This article sets out to examine whether there is likely to be a free market in these sectors and assesses the progress being made since the introduction of a number of procurement directives post-1998. This will therefore have an influence on land use planning. The article draws on the literature of regulation and industrial organization as well as European integration in order to demonstrate the complexities of these industries and the problems of full compliance with the single market. 相似文献

Blue Mountains City is a unique urban area of 75 000 people, located along a narrow mountain ridge and within a world heritage national park, between 60 and 120 kilometres west of Sydney, New South Wales, Australia. The Blue Mountains City Council is currently developing a regional city strategy to guide development over the next 25 years. All sections of a very diverse community have been consulted in the public participation process, including children aged between six and 12 years. This paper deals with the analysis of 269 entries for a children's story-writing competition organised by the council. The children had to imagine that they were adults in 2025 and write a story about what their home and city would be like at that time. The paper discusses the complex problems of consulting with children on strategic regional planning matters, and the results from analysis of these competition entries in the light of those problems. The most important issues for the children as a whole were the impact of traffic, the impact of urban development on residential neighbourhoods, places for children to play, protection of the natural environment, for which the city is famous, and the ability to keep domestic pets. One of the most significant impressions emerging from the analysis is that children were far from optimistic about the future. Thirty-five per cent of entries had a negative tone, whereas only 24% were positive. The remaining 41% were written in a matter-of-fact narrative style that indicated neither enthusiasm nor disappointment with the future of the city. The children were more or less evenly divided on whether the future would be strongly based on advances in technology, much the same as now, or based on simpler technology than at present. The technique of story writing, despite some methodological difficulties in this particular case, was a useful tool for consultation with children of this age group. 相似文献

The concept of human security, while much contested in both academic and policy debates, and highly fragmented across different meanings and forms of implementation, offers a potential locus around which global security discourse might converge, particularly in light of current shifts in US security thinking. However, key pioneers of human security, such as the United Nations and Canada, appear to be losing their enthusiasm for the concept, just at the moment when others such as the European Union, are advancing a human security agenda. This article examines the divergence of human security narratives between the UN and the EU. It argues that the UN's use of the concept ran aground owing to a triple problematic of lack of clarity, confusion between previously distinct policy streams on human rights and human development and conceptual overstretch. After assessing the EU experience with the concept to date, the article argues that future use of human security will require greater focus on how it deepens ideas of individual security, rather than treating it as an agenda for broadening security. As well as a need to project clarity on the conceptual definition of human security, there is also a need to associate human security with greater clarity of intent. If successful, this would contribute to establishing second generation human security as a new policy paradigm. 相似文献
