A high-resolution chronostratigraphy has been established for an eroding Atlantic round house at Sloc Sàbhaidh (North Uist, Scotland), combining detailed OSL profiling and dating of sediments encompassing the main bracketing events associated with the monument, radiocarbon AMS dates on bone recovered from excavated features and fills within it, and TL dates on pottery and burnt clay. Concordant OSL and radiocarbon evidence place construction of the wheelhouse in the first to second centuries AD, contemporary with dates from the primary occupation. Beneath the wheelhouse, clay deposits containing burnt material, attest to cultural activity in vicinity to the monument in the preceding second to first centuries BC. At a later date, the southern wall collapsed, was rebuilt, and the interior spaces to the monument re-structured. The chronology for the later horizons identified from the sediment luminescence dates extends to the second half of the first millennium AD, which goes beyond the range of the radiocarbon dates obtained. The data from ceramics encompass both periods. The juxtaposition of the dating evidence is discussed relative to short and longer chronologies for this Iron Age monument. Corollaries of this research are the implications that based on the long chronology, some of the ecofacts (bone) appear to be residual, and that the temporal duration of Hebridean Coarse Ware may extend into the second half of the first millennium AD.  相似文献

The impacts and activities of international retailers have beenlargely ignored in the globalisation discourse. A possible reasonfor this is the absence, in international retailing, of conceptand theory that does not hang on the coat-tails of internationalproduction. The paper attempts to consider international retailingin its own right. Three linked questions are explored. Has theinternationalisation process of the large retailers resultedin an increase in the global concentration of sales? In whatways does the process of retailer internationalisation differfrom the internationalisation of production? What does the committedinternational retailer transfer to the host country during theinternationalisation process?  相似文献

Recent attempts to develop scientific research strategies for cultural evolution have mostly drawn upon evolutionary biology, but within anthropology there is also an influential tradition of non-biological evolutionary thought whose basic principle is adaptation to the environment. This article is mainly concerned with the "cultural materialist" school of Marvin Harris, but also treats the recent attempt of Jared Diamond to create a more radical model of evolutionary ecology. I argue that the ecological tradition does not represent a real alternative to neo-Darwinism and is in fact a pseudo-Darwinist theory. I also suggest that the bias in favor of materialistic explanation in cultural evolution may not be justified.  相似文献

Tin, as a constituent of bronze, was central to the technological development of early societies, but cassiterite (SnO2) deposits were scarce and located distantly from the centres of Mediterranean civilizations. As Britain had the largest workable ore deposits in the ancient Western world, this has led to much historical speculation and myth regarding the long-distance trading of tin from the Bronze Age onwards. Here we establish the first detailed chronology for tin, along with lead and copper deposition, into undisturbed ombrotrophic (rain-fed) peat bogs located at Bodmin Moor and Dartmoor in the centre of the British tin ore fields. Sustained elevated tin deposition is demonstrated clearly, with peaks occurring at 100–400 and 700–1000 calendar years AD – contemporaneous with the Roman and Anglo-Saxon periods respectively. While pre-Roman Iron Age tin exploitation undoubtedly took place, it was on a scale that did not result in convincingly enhanced deposition of the metal. The deposition of lead in the peat record provides evidence of a pre-Roman metal-based economy in southwest Britain. Emerging in the 4th century BC, this was centred on copper and lead ore processing that expanded exponentially and then collapsed upon Roman colonization during the 1st century AD.  相似文献

Magnetometry has been little used on Arctic archaeological sites, but has great potential to help us understand site structure by identifying buried features and providing additional detail about the construction and use of visible surface features. In the Arctic environment, magnetometer surveys have to deal with the effects of permafrost activity on soils and the potential influence of glacial erratics of varying geological composition. Here, we present the results of magnetometer surveys of a non-cultural site with periglacial features and two archaeological sites located in the Canadian low Arctic. Despite considerable “noise” apparently caused by igneous erratics, the surveys successfully identified several frost features and a range of archaeological feature types. They also appear to have located buried archaeological features and identified activity areas within some dwellings. These preliminary results suggest that the technique is worth pursuing on northern sites.  相似文献
