The regulation of scientific and archaeological diving is complex but it is essential that underwater archaeologists are familiar with the requirements placed on them by legal systems. This paper outlines the history and development of current legal systems in four jurisdictions: the UK, USA, EU and Australia. This historical and legal approach informs key discussions facing maritime archaeologists; reference is made to training requirements, safety records and the question of who should be allowed to participate and who should be excluded from archaeological diving. 相似文献

Sulphur isotopes in archaeological bone collagen are not routinely analysed in palaeodietary studies. Here we investigate the potential contribution that sulphur isotope analysis can provide toward the study of ancient human diet and economy, with particular emphasis on the distinction between freshwater and terrestrial consumers. For material from the Late Bronze Age site of Chicha in the south-western Eurasian forest-steppe, sulphur isotopes effectively separate freshwater and terrestrial animal food resources. The sulphur isotope data coupled with nitrogen isotope values from Chicha reflect a dietary reliance upon freshwater animal protein (fish) for the Late Bronze Age inhabitants. In contrast, sulphur isotope values for freshwater and terrestrial potential food species from the Eneolithic site of Bil'shivtsi in western Ukraine were indistinguishable, demonstrating that δ34S values cannot always be relied upon to identify freshwater and terrestrial consumers. The data from this study support the adoption of δ34S analysis as a standard component of palaeodietary studies; apart from its potential to distinguish freshwater from terrestrial consumers, it can provide supplementary dietary information not evident from the carbon and nitrogen isotope data. In addition, certain indices are considered that may be used to assess the validity of sulphur isotope data, as currently exist for carbon and nitrogen. According to the analysis of modern collagen samples, N:S appears to be a broad indicator of collagen sulphur isotope quality. However, more work needs to be done to establish an effective means by which highly-altered sulphur isotope values can be identified and thereby removed from consideration. 相似文献

The science of anthropology obtains data on health, disease and death from ancient populations. Research on the skeletal remains of human teeth and surrounding tissues provides useful information on the evolutionary perspective of dental and periodontal diseases. The aim of this study was to determine the prevalence and severity of periodontal diseases in the skeletal remains of 33 Assos inhabitants of the 4th century BC. Three age groups were constituted for the studied population. Periodontal disease status was determined based on the textural and architectural variations of the interdental septum and the extent of bone loss. It was found that the prevalence of periodontal diseases increased with age. The severity of periodontal bone loss also increased with age and the mean alveolar bone loss between age groups was statistically significant (P = 0.004). This analysis of the dental health of ancient populations provides insights into the aetiology, patterns and distribution of periodontitis, which has a very complex disease pathogenesis.

A fundamental observation of 21st century cities is that they have become great centers of consumption. In this paper, we seek to understand the geographic variation in consumer behavior. Using Consumer Expenditure Survey (CE), we analyze how consumption differs across 21 major U.S. metropolitan areas, and the association between urban characteristics and consumption. We extend previous geographic analysis of consumption to include luxury goods that are socially visible (conspicuous consumption) and luxury goods that are relatively less visible (inconspicuous consumption). Our analysis shows that conspicuous consumption is more sensitive to an urban context than is inconspicuous consumption. 相似文献

“京观”是中国古代战争的产物,贯穿于中国历史的上古和中古时期,为华夏民族和周边兄弟民族所采用,目的是张扬武功。但是,由于“京观”这种形式过于血腥与残酷,故在以后的岁月不被使用;时至现代,演变为纪念碑的形式。 相似文献

The introduction to this special issue of five essays on the historical geography of islands considers the growing interdisciplinary interest in the material and metaphorical condition of islands. It explores how the physical and literal attributes of islands have a range of understandings such as the catalytic role of islands in shaping the modern disciplines of social anthropology and evolutionary biology. Thereafter, the Falkland Islands are used to illustrate how the complex interplay of physical and metaphorical meanings have profound implications for territorial nationalism in this case the South West Atlantic. Long viewed as an abstract territorial space, the history and geography of the Falklands reveals how islands should never be seen as simple or straightforward. The final section of this introduction details the five contributions and highlights how each author not only explores the geographical and cultural diversity of islands but also traces some of the implications for human understandings of these remarkable environments. 相似文献

The oil refinery/petro‐chemical complex at Grangemouth has played an important part in the rise of the United Kingdom petro‐chemical industry which has been one of the most dynamic elements of the nation's manufacturing sector.1 The complex has a special significance within Central Scotland in view of the contrast between its rapid development and the declining fortunes of the traditional industrial base. This paper analyses its structure and development and also examines its role as the focus of official attempts to promote Grangemouth/Falkirk as a ‘growth centre’. 相似文献

Morphological characters for the separation of red and fallow deer remains are described. These encompass antlers, permanent dentition, and postcranial bones. The characters were tested on samples of known red and fallow deer from an array of contexts, thus helping to ensure their validity across different populations. An attempt is made to quantify the reliability of each character, using a simple arithmetic method of scoring and analysing the test data. This forms the basis for a more objective assessment of the identity of an unknown specimen. 相似文献
