Conservation of built heritage is a key planning process and goal which shapes urban development outcomes across European cities. In Ireland, conservation of the built heritage is a key part of the planning framework, albeit one that is, in comparative terms, only recently established. While it is widely recognized that the underlying rationale for conservation of built heritage varies considerably (from cultural priorities to place marketing), the literature suggests that heritage and conservation professionals perform a key role in controlling decision-making through an official or “authorized” heritage discourse (AHD), emphasizing expert values and knowledge and based around selective heritage storylines often reflecting elite tastes. Drawing on policy and practice in Ireland, in this paper, we contribute to these debates by further unpacking the AHD, exploring tensions within the heritage policy elite through examination of competing views and representations relating to the purpose of built heritage protection. Based on a discourse analysis following interviews with key national actors, we identify two key narratives—a “museum-curatorial” discourse and an “inclusive heritage” discourse—which in turn frame conservation practices. We argue that subtle variations of heritage meanings have the potential to either reproduce (museum-curatorial discourse) or challenge (inclusive heritage discourse) conventional modes of practice, particularly relating to the relationship between built heritage and identity and the role of public engagement. 相似文献

Offshore submerged sites can retain valuable data concerning many questions of interest to archaeology, including what form coastal occupations may have taken during periods before the establishment of modern coastlines and late Holocene climate and ecological conditions. However, submerged offshore sites experience postdepositional forces entirely unlike those in terrestrial contexts, including erosion/deflation of sediments, and degradation of artifacts and/or features caused by the marine environment. Methodological and theoretical approaches to assessing submerged marine sites, versus terrestrial ones, must be adjusted accordingly to extract valuable data and interpretations from them. This study demonstrates the application of these different approaches at the Econfina Channel site (8TA139) in Apalachee Bay, Florida, USA. The site appears to contain significant evidence for coastally adapted occupation during the final part of the Middle Archaic period (~8600–5000?cal?BP), but we needed to address marine site formation processes before we could assess human activities at the site. Sedimentological and archaeological traces of human activities can be teased out using geoarchaeological methods, which differentiate between nonhuman postdepositional processes and the cultural material remains left behind by those who used the site before it was abandoned and subsequently submerged. 相似文献

The paper presents an algorithm for computing the parameters of an ellipse that fits, in a least-squares sense, the surveyed remains of Roman amphitheatre arena walls. The algorithm is validated using ideal data and the near complete remains of the amphitheatre at Sarmizegetusa in Romania. The technique is then applied to the partial remains of the amphitheatre at the Guildhall in the City of London, in the UK, which cover only the Eastern end of the monument. The underlying mathematical model and method of solution is presented. The method was developed with a view to determining firstly whether or not an ellipse is a feasible model for the actual constructed curve geometry, and secondly, where the Western end of the Guildhall amphitheatre might be located. One single ellipse was found to fit the Guildhall remains, with measurement residuals at the level of 30 mm in the eastings and 26 mm in the northings. The ellipse had a semi-major axis of 28.345 m and a semi-minor axis of 22.775 m. The issues of alternative geometries and the practicalities of their use in construction are considered. 相似文献

This article presents an analysis of the Polish-German scholarlyand public debate of the last decades dedicated to the fateof the German population in Upper Silesia after the ending ofthe Second World War. In the introduction, three determiningfactors of the current discussion are mentioned: first, thepublic debate on this topic, which evolved especially afterthe turning point of the democratization in Poland in 1989,and which created a certain social climate for these scholarlydebates; secondly, the history of the Polish-German conflictin Upper Silesia, which conditioned the post-war situation inthe region; and thirdly, the main historiographical paradigmsto the subject before 1989 in both countries, whose fixationand whose deficits weighed heavily upon the research directionchosen in this period. From among these three aspects—the camps built for theGerman population, their resettlement, and the politics of nationalitytowards former German citizens, who were then recognized asowners of Polish nationality and who could remain in their homes—thearticle concentrates on the first one. The last few years sawthe most fundamental revision concerning the camps for the Germanpopulation, and our knowledge is here relatively complete. Itis worth underlining that most advances here have been achievedby Polish historians from various disciplinary directions. 相似文献
