The construction of the Baptistry of Saint John has a debated and uncertain history; the hypothesis on its main construction phases may span from the Roman period to the 13th century, according to different authors. This uncertainty is mainly due to the lack of primary sources and certain dating issues. By combining dendrochronological analysis and radiocarbon dating, some light was shed on the building’s history. Open at least from 897, in 1059 Pope Nicholas II re-consecrated the baptistry after several renovations. Around that period, the octagonal dome was probably built by using chestnut beams to tie the structure together. The dendrochronological analysis dated the silver fir element to 1268. This element possibly represents a replacement coincident with the period, between 1270 and 1300, when a substantial part of the mosaics of the dome was positioned.  相似文献

The paper discusses the potential of a collaborative scheme for the development of a protocol for recording and managing the cultural heritage in Libya. The critical political situation in the country urges the development of cultural heritage management policies in order to protect it more thoroughly and consistently. Moving on from the numerous international initiatives and projects dealing with a mostly “remote” approach to the issue, the project here presented to engages with staff members of the Department of Antiquities (DoA) in the development of a joint strategy for the application of remote sensing and geographical information systems (GIS) to the preservation and monitoring of Libyan cultural heritage. A series of training courses resulted in an initial development of new ways of recording and analysing field data for a better awareness of the full range of threats that the archaeology of the country is subject to. Focussing on the case of the Jebel Nafusa, the training involved the assessment of site visibility on satellite imagery, the analysis of high-resolution satellite datasets for archaeological mapping, the creation of a GIS spatial database of field data, and the mapping of risks and threats to archaeology from remote sensing data. This led to the creation of of a risk map showing the areas that are affected by a number of threats, thus giving the DoA a tool to prioritise future fieldwork to keep the assessment of site damage up to date. Only a collaborative approach can lead to a sustainable strategy for the protection of the invaluable cultural heritage of Libya.  相似文献

Abstract

Youth have been a malleable resource in the fight against hunger, variously conceived as volunteers, political activists, global citizens and financial donors. This article uncovers competing (and sometimes complementary) visions for the participation of British youth in Youth Against Hunger, part of the United Nations Freedom from Hunger Campaign. In doing so, it makes two key contributions to the field. First, by uncovering the professionals and commentators who sought to involve adolescents in humanitarian activity, it accounts for the agency of a more diverse range of non-state participants and experts than are usually included in histories of humanitarianism. Second, in highlighting the pragmatic difficulties in aligning humanitarian and youth-work contexts, it illustrates how domestic concerns about British youth actively shaped the development of the humanitarian sector in this period.  相似文献

This article examines the concepts of democracy and legitimacy in the context of post-Soviet Central Asia. Its first argument is that democratization projects have lived through hard times in five Central Asian countries despite the failure of the institutional expression of democracy to incorporate the values and structures of these societies. The Soviet legacy of cynicism combined with local conservative political culture obstructs the emergence of democratic values and processes crucial for successful institutional development. If democracy does not provide a basis for political legitimacy, should the conclusion be that the ruling regimes are illegitimate? The article’s second argument is that the current sources of legitimacy stem from the fact that the regimes managed to cope with the initial challenges of post-communist transition with relative success and laid the foundation of the new states. Moreover, the populations do not see viable alternatives to the present order. However, there are new problems, such as mounting social tensions, regionalization and criminalization of politics. These challenges are largely a by-product of developments in the post-independence era. The continuing legitimacy of the regimes will depend on their ability to cope with these new, highly problematic issues.  相似文献

There are few described cases of metastatic carcinoma from the prehistoric eastern United States and none primarily differentially diagnosed from the southeast. A mature adult female exhibiting several large lytic cranial lesions suggestive of neoplastic disease was identified in a late prehistoric Mississippian Period (AD 1200–1600) context. Burial 371 is from Ledford Island, a Mouse Creek phase (AD 1400–1500) site from the Chickamauga Reservoir of southeastern Tennessee. It is the only case in this reservoir (total adult n = 843). The radiographs of the otherwise asymptomatic postcranium yielded radiolucencies in both proximal femora, both medial clavicles, the sternum, the surviving humeral metaphysis and fragmentary innominate. The locations are all consistent with metastasized carcinoma. The identity of the possible primary lesion is argumentative. Age, sex and the mixed nature of the osseous response are consistent with carcinoma of the breast but not to the exclusion of bronchogenic, thyroid, or kidney cancers.

An integrated remote-sensing survey was carried out in Navarino Bay, where in 1827 a battle was fought between the allied British, French and Russian navies and the Turkish-Egyptian fleet. Integration and interpretation of the remote-sensing data has shown the presence of shipwreck remains on the sea-floor and possible shipwrecks buried under the sea-bed. It has also shown that the historical remains are under threat from the heavy anchors of tankers which sink into the sea-bed and, when dragged, dig furrows, thus disintegrating the shipwreck remains. To protect the sites the construction of permanent anchoring systems away from the shipwreck remains is recommended.

ABSTRACT This paper surveys recent evidence on the determinants of (national and/or foreign) industrial location. We find that the basic analytical framework has remained essentially unaltered since the early contributions of the early 1980s while, in contrast, there have been advances in the quality of the data (more firm and plant level information, geographical disaggregation, panel structure, etc.) and, to a lesser extent, the econometric modeling. We also identify certain determinants (neoclassical and institutional factors) that tend to provide largely consistent results across the reviewed studies. In light of this evidence, we finally suggest future lines of research.  相似文献
