New work at Kehf el Hammar Cave provides the first well-dated palaeoenvironmental sequence for the Late Upper Palaeolithic in this region of the northwest Maghreb. The archaeological layers are dated via a combination of AMS radiocarbon and luminescence dating methods. The sequence contains charcoal-rich occupation layers with faunal, human and lithic finds. Local vegetational patterns are reconstructed on the basis of preliminary analysis of the charcoal evidence. Using standard calibration curves the AMS radiocarbon dates are compared with proxy evidence for climatic change from sea core records in the Alborán Sea. These appear to show that the Late Upper Palaeolithic occupation of the region coincides closely with Heinrich Event 1, a period marked by intense aridification and dating to ca. 16,700–17,250 calendar years ago.Les nouvelles recherches dans la grotte de Kehf el Hammar ont permis d’obtenir la première séquence paléoenevironnementale bien datée du Paléolithique supérieur tardif au Nord Ouest du Maghreb. En effet, les niveaux archéologiques ont été datés par le radiocarbone par accélérateur (AMS) et des méthodes radiométriques basées sur la luminescence. En revanche, les paléoenvironnements végétaux ont été partiellement reconstitués à base des premières analyses des charbons de bois. Les dates AMS calibrées ont été comparées aux données climatiques issues des carottes marines dans la mer Alborán. Ainsi, les occupations humaines du Paléolithique supérieur tardif dans la région ont sensiblement coïncidé avec l’événement climatique Heinrich 1. Celui-ci correspond à une période qui a été marquée par une aridification intense entre 16.700 et 17.250 ans (cal.). 相似文献

This article explores a series of tensions inherent in the series of European policies that are designed to improve the competitiveness of regions in the face of globalization. Its focus is the co-existence of interventionist policies intended to overcome problems of lagging regions such as cohesion policies and those, for example competition policy which are designed to remove barriers to market integration and that are anti-interventionist. Moreover, the changing relationship between the European Union (EU), member states and the regions and problems of how regions are defined complicate policy implementation. To review these issues, the article adopts an agent-centred approach to understanding economic behaviour in the face of globalization in particular geographical and sectoral contexts. This methodology is used to highlight five sources of tension relating to the reality of the experience of globalization. These are illustrated by evidence from a recently completed EU Fifth Framework Programme study of regional adjustment strategies and technological change in five European countries. 相似文献

The authors urge a zonal specialization of agriculture within the countries of the Socialist camp, particularly the CEMA grouping. Bulgaria, which supplies tobacco, grapes, early vegetables, and fruits to other countries, in cited as an example. Geographers are urged to work out such a specialization scheme based on a complex of factors, including the physical-geographic base, manpower resources, the present state of agriculture, and the traditional working habits of the population. 相似文献

SUMMARY: In 2014, during construction work at the ex-Civil Hospital in Gibraltar, excavations led by the Gibraltar Museum revealed a major, previously unknown burial ground containing more than 200 skeletons. We present the historical, archaeological and radiometric dating evidence from the site alongside the results of initial osteological analyses. The data indicate that the burials pertain to an earlier 16th-century Spanish hospice, and therefore stand to offer new insights into the functioning of this early modern hospital and the health and movements of people at a time of incipient globalization. 相似文献

A meeting of the Advisory Panel on a major research project entitled “Soviet Environmental Policies and Practices: Most Critical Investment Priorities” was convened in Glasgow, Scotland on March 12 and 13, 1988. More than a dozen specialists from Britain, West Germany, and the United States participated. The meeting was hosted by the Institute of Soviet and East European Studies of Glasgow University. The results are summarized below. 相似文献

The establishment of a new ethnos, or ethnic community, is attributed to a burst of energy or an innate drive that enables members of the community to break with past traditions and behavioral patterns and to begin building a new set of values distinguishing the new ethnic group from others. The ethnos is viewed as both a social and a biological phenomenon, with the social aspect represented by the group's relations with other groups and institutions and the biological by the behavior of the ethnos as a biological population. The innate drive exhibited by ethnic groups in the early stage of ethnogenesis is viewed as a biological feature. In general this drive is fostered by the practice of endogamy, but there are situations in which an ethnically mixed community, resulting from exogamy, also generates the energy required to initiate the process of ethnogenesis. Although the existence of the ethnic drive can be demonstrated by reference to history and historical geography, an explanation of this form of energy must be left to genetics and anthropology. 相似文献

Limiting environmental conditions in the construction of industrial nodes in the new oil district of the Middle Ob' are the rigorous climate, extensive swamp cover and absence of ground transportation. These adverse factors are compensated to some extent by the shallow depth of oil deposits, favorable geology and the availability of groundwater that can be injected to maintain oil-reservoir pressures. The basic problems in the development of the oil district are the shortage of housing, services and local foodproducts and consumer goods as well as the high cost of construction of transport routes. Greater investment in services is urged to help reduce the high turnover of labor as migrants are reluctant to settle permanently in the region. 相似文献

Populonia is commonly regarded as one of the most important iron working centres in Europe in the 1st millennium BC. However, multiple layers of copper slags have been recently discovered at the bottom of the slag deposit occurring along the shoreline of the underlying Baratti Gulf. Copper slag layers have been radiocarbon dated to the 9th–8th centuries BC, i.e. to an early metallurgical stage predating the later large-scale iron production. The overall features of copper slags indicate a single-step smelting process of copper-rich ores containing variable amounts of Zn and Pb. Chemical and textural features of copper slags indicate an optimised, high-efficiency metallurgical process. 相似文献
