Fifty‐seven glass samples from Carthage dating to the fourth to sixth century ad were analysed using the electron microprobe. The results show that these samples are all soda–lime–silica glass. Their MgO and K2O values, which are below 1.5%, suggest that they were made from natron, a flux that was widely used during the Roman period. The major and minor elements show that these samples can be divided into four groups, three of which correspond to the late Roman period glass groups that were found throughout the Roman Empire: Levantine I, and ‘weak’ and ‘strong’ HIMT. Of particular interest is our Group 2, which is technologically and compositionally similar to HIMT glass and the CaO and Al2O3 values of which are similar to those of Levantine I. Glass of similar composition has been reported by several authors and is predominantly found dating from the late fifth to seventh century. This could represent a ‘new’ glass group; therefore further study is needed to determine its origin. Also, this study suggests that the Vandal invasion in North Africa did not disrupt the glass trade between Carthage and the Levantine coast.  相似文献

This article examines how digital heritage, in the form of 3D digital objects, fits into particular discourses around identity, ancestrality and cultural transmission in Melanesia. Through an ethnographic analysis of digital heritage use amongst the Nalik community in New Ireland (Papua New Guinea), it demonstrates how digital heritage is understood not in terms of deceit and a loss of authenticity, but instead, towards an understanding of authenticity in terms of completeness and integrity. A notion of completeness and integrity, I argue, has the effect of creating an authentic experience of the past for Nalik communities by bringing back museum objects (‘old’ objects) that have been dispersed amongst museums and heritage institutions worldwide. In tracing out the operations and effects of how a Melanesian community engages with 3D digital objects, this article offers unique ethnographic insights into digital heritage in ways that challenge widely-held assumptions about the heightened value placed on the original object over its digital counterpart.  相似文献

Archaeological monitoring of construction in a Windsor city park on the Detroit River led to the discovery of an isolated cemetery containing the remains of eight individuals assigned to the Late Woodland Western Basin Tradition. At the request and consent of the contemporary First Nation community, tissue samples from five individuals were subjected to radiocarbon dating, mtDNA, and stable isotope analysis to confirm cultural affiliation and further understand the subsistence practices of these people. Radiocarbon dating placed the cemetery at the transition from the Younge phase (AD 900–1200) to the Springwells phase (AD 1200–1400). The stable carbon and nitrogen isotope results provide an unexpected but fuller understanding of Late Woodland Western Basin Tradition subsistence. All individuals were as enriched in carbon as those found on Iroquoian horticulturalist sites to the east, suggesting a very high reliance on maize. Nitrogen isotope values indicate that the protein component of the diet was comprised largely of high trophic level food sources, likely fish. An in situ osteological analysis identified a high number of carious lesions in the visible teeth, also suggesting a diet high in carbohydrates. The mtDNA findings support the antiquity of the Western Basin presence in Northeast North America through genetic links with the Hind Site, an Archaic site in southern Ontario. These results underscore the importance of such studies for providing novel insight into the archaeological histories and lifeways of this distinct Late Woodland tradition. This study also emphazises the need to work with descendant communities to provide them with information on the past that reflects their distinct heritage in the lower Great Lakes region.  相似文献

Polynomial Texture Mapping is an image capture and processing technique that was developed by HP Labs in 2000. It enables the recording and representation of subtle surface details using a standard digital camera and lighting, and software that is free for non-commercial use. Cultural heritage applications have been associated with the technology from its earliest stages, including examples in areas such as cuneiform, numismatics, rock art, lithics and Byzantine art. The paper begins by outlining the technical principles involved. It then brings together the extant work in the field. Through examples developed by the University of Southampton in partnership with a range of UK and international bodies it demonstrates the benefits of the technology in the areas of archaeological analysis, conservation and representation. Finally it considers the future possibilities of this technology and ongoing developments.  相似文献

This paper shows that the focus of Australia's ‘declared’ defence policy has oscillated between local and regional defence, whereas its ‘operational’ policy—the views contained in internal planning and guidance documents—has taken a mid‐course, focusing on defending Australia's northern approaches. Australia's two policy domains coincided briefly in the mid‐1980s but have since diverged as we have again begun to emphasise regional defence. This shift could signal the end of ‘defence self‐reliance’. While representing a setback for the Hawke government, such a result is necessary as Australia's ‘operational’ policy is flawed and in need of replacement The danger is that, as in the past, Australian governments and their advisers will continue to adjust their rhetoric rather than their real policies to our changing circumstances.  相似文献

The dominant theme in court reorganization has been to state judiciaries by consolidating trial courts and centralizing their administration in a state level office. This article suggests that the debate over the relative merits of a centralized vs. a decentralized (or fragmented) court system ignores the rich variety of organizational structures used in other fields. The potential judicial implications of three models-franchise, corporate, and federal-are examined in detail. Their underlying assumptions are compared with those of the centralization approach. The argument is made that none of the models is appropriate for all circumstances. Each approach to court organization emphasizes a particular set of objectives at the expense of another set. An effort is made to identify what each approach has to offer.  相似文献

On 27 June 2000, the Howard Government released a public information paper on defence which set in train a process of public consultation in which the people's views were sought on a range of defence and defence-related issues. This paper examines why the Government chose to go to the people, how and by whom the community consultation was conducted, who was consulted and listened to, and how what was heard at the public meetings component of the process was both interpreted and reported. The paper concludes that the public consultation process was more about politics than policy; it is inappropriate for the Government to claim or imply that it has heard from the 'Australian people' or even 'the majority of the community' on the issues raised; and the consultation process and its outcomes are not entirely risk-free for the Government and the defence establishment.  相似文献
