ABSTRACT

This paper employs δ13C and δ15N analysis of bone collagen to explore animal management at large Norse settlement sites in the liminal environments of the Scottish North Atlantic Islands. The Norse period was a time of social, cultural and economic change; the need to feed an expanding population and the demand for trade meant that domestic stock were a crucial resource. Our results indicate that rearing animals in these challenging insular environments required careful management. At all sites, the diet and movement of domestic cattle and sheep were highly similar and carefully controlled and, despite many of the analysed settlements lying close to the coast, there was no use of shorefront grazing or fodder resources. In contrast, pig rearing strategies varied across the island groups. In the Western Isles pig diets were diverse, indicative of household or ad hoc management, whilst on Orkney all pigs consumed a more restricted diet based primarily on terrestrial protein. A comparison of red deer with domestic stock on the Western Isles indicates that both groups were exploiting similar grazing niches.  相似文献

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

山东青州邢氏原是务农的家族,在邢玠科举成功为官之后,转型为官宦之家,成为地方望族。从万历时的邢玠开始,到崇祯时的邢彤庭,邢氏从事宗族建设,制定并实践各种宗族制度,宗族乡约化、组织化。邢氏受到宋代程颐、程灏的宗会思想很大影响,通过"宗会"复兴"宗法"。这是宋以后宗族组织化的一种重要模式,以往的宗族研究重视不够。邢氏也编修了族谱,有家庙或者家堂,将御赐的祭田作为族田,还设置了宗学、义仓,族长实际上就是宗正。邢玠受到苏洵苏氏谱法以及睦族主张的影响较大,邢氏族谱着眼于睦族,收录大量宗族制度的文献,内容非常丰富,面貌大为改观,成为重要的民间文献。晚明不仅再造宗族,也再造了族谱,完成了中国近世宗族与族谱的基本形式。  相似文献

This article examines the evidence that inhabitants of islands with more than one polis (city-state) in the Aegean in the Classical and Hellenistic periods identified with their islands rather than with their individual poleis. Island rather than polis identity is expressed in the use of ethnic names in epigraphic and literary evidence from both the island world and outside it. The use of the island ethnic name indicates that politically fragmented islands had a strong sense of unity. This sense of unity was also expressed in action: practices such as minting coins, engaging in political unifications and forming island federations, participating in pan-island cults, and appearing in the form of group assessments in the Athenian Tribute Lists are seen as examples of the manifestation of a common island identity. Examination of attestations of island identity suggests that, although the ways in which this kind of identity was felt and expressed were probably diverse, the geographical separation of islands allowed for islanders to overcome probable local tensions and individual differentiations and seek ways of self-identification and of expression of political-religious-economic collaborations alternative to the polis.  相似文献

The article here presented focuses on the intellectual development of Fernand Braudel's pre-1949 approach to Ottoman history, tracing its origins in his work undertaken on and in North Africa in the late 1920s, and its subsequent development down to the appearance in 1949 of his major work, La Méditerranée et le monde méditerranéen à l'époque de Philippe II and the immediate post-publication reception of Braudel's epochal work in Turkey. The reaction of contemporary Turkish scholarship to the economic and demographic aspects of La Méditerranée, together with its links with the Annales school, is examined, as is the later, mainly North American, response to the political and diplomatic aspects of Braudel's work. Enquiry is made of common links from both Braudel's and the Ottoman side with the work of Henri Pirenne, together with the significance of Braudel's own work as in instrument for bringing Ottoman history more into the overall history of the Mediterranean world in the early modern period.  相似文献

The INTIMATE (Integration of ice-core, marine and terrestrial records) project, the successor to the North Atlantic Seaboard Programme of International Geological Correlation Programme (IGCP-253) ‘Termination of the Pleistocene’, began in 1995 with the aim of integrating proxy climate records from around the North Atlantic during the Last Termination (18–8?ka BP). The INTIMATE remit has since expanded geographically to include the entire Atlantic basin and Australasia, while an extended temporal framework now covers the early Holocene and the Last Glacial cycle. This short paper outlines the principal achievements of the INTIMATE research community, which include the development of an event stratigraphy for the North Atlantic region; the establishment of protocols for ice–land–ocean correlation; important contributions to geochronology, most notably to tephrochronology, and to palaeoenvironmental and palaeoclimatic reconstructions; and the designation of the Greenland ice-core record as the global stratotype for the Pleistocene–Holocene boundary. Future directions of the INTIMATE programme are also briefly considered.  相似文献

This paper develops the concept of territorial socialisation and explores the process and effect of tourism in China's maritime territorialisation of the South China Sea. The research demonstrates the mutual constitution of tourism and territorialisation and suggests that tourism is playing an increasingly important role in everyday contexts to socialise individuals into national-territorial thinking. However, tourism alone does not decidedly stoke strong territorial nationalism, instead it produces uneven bordering or territorialisation effects at the personal level. Tourism practices, tourist agency, and the distinct wet ontology of the sea complicate the state maritime territorialisation process. The research also shows that the Chinese tourists are pragmatic, calculative geopolitical actors. Their geopolitical experiences through tourism are connected to, and embedded in, the broad geopolitical realities of China's rising and unjust international orders, while informed by official territorial rhetoric and traditional political culture.  相似文献

This paper summarises the current development in the southern Ionian Islands (Kefallinia and Zakynthos) prehistory and places it within the context of seafaring. Archaeological data from the southern Ionian Islands show human habitation since Middle Palaeolithic going back to 110 ka BP yet bathymetry, sea-level changes and the Late Quaternary geology, show that Kefallinia and Zakynthos were insular at that time. Hence, human presence in these islands indicates inter island-mainland seafaring. Seafaring most likely started some time between 110 and 35 ka BP and the seafarers were the Neanderthals. Seafaring was encouraged by the coastal configuration, which offered the right conditions for developing seafaring skills according to the “voyaging nurseries” and “autocatalysis” concepts.  相似文献

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic.  相似文献
