Current understanding of the Iron Age polity of Phrygia in Central Anatolia is primarily based on excavations and survey in the region of the Phrygian capital of Gordion. In order to expand our knowledge of the Phrygian polity, we assess the scale and nature of Iron Age communities in the western (Eski?ehir) region of Phrygia. We address the challenge of interpreting ceramics derived from large-scale archaeological survey by utilizing Neutron Activation Analysis (NAA) of ceramics from 12 sites across the region collected by the Eski?ehir archaeological survey project as well as an excavated assemblage from ?ar H?yük. While the uniformity in ceramic technology and styles suggest the region is part of the larger Phrygian community, NAA results reveal that (a) ceramic production was regionally highly localized with limited evidence of standardization during the Iron Age and (b) based on evidence of community interaction it is possible to establish a partial chronological sequence of development. These results have implications not only for understanding the internal dynamics within the Phrygian core but also for developing a methodology for comparing ancient polities using commensurate units of interacting communities. The present study is part of the larger Anatolian Iron Age Ceramics project (http://www.une.edu.au/a-ia). 相似文献

ABSTRACT This study estimates the impact of sea‐level rise on coastal real estate in North Carolina using a unique integration of geospatial and hedonic property data. With rates of sea‐level rise approximately double the global average, North Carolina has one of the most vulnerable coastlines in the United States. A range of modest sea‐level rise scenarios based on the IPCC Fourth Assessment Report projections (2007) are considered for four counties of North Carolina—New Hanover, Dare, Carteret, and Bertie—which represent a cross‐section of the state's coastline in geographical distribution and economic development. High‐resolution topographic LIDAR (light detection and ranging) data are used to provide accurate inundation maps for the properties that will be at risk under six different sea‐level rise scenarios. A simulation approach based on spatial hedonic models is used to provide consistent estimates of the property value losses. Considering just four coastal counties in North Carolina, the value of residential property loss without discounting in 2030 (2080) is estimated to be about $179 ($526) million for the mid‐range sea‐level rise scenarios. Low‐lying and heavily developed areas in the northern coastline are comparatively more vulnerable to the effect of sea‐level rise than the other areas. 相似文献

This article analyzes the mechanisms through which metropolitan governance is established in Montreal's aeronautics sector, one of the most important and innovative industries in the region. The article also examines the role of lead firms, socio‐economic actors, and public agencies from a territorial point of view. It is established that on the one hand the existence of a small number of prime producers at the local level facilitates productive linkages among businesses through subcontracting, and on the other hand, the intensive participation of intermediate socio‐economic agencies and organizations ensures a metropolitan anchoring of the sector and creates a strong territorial identity among the players. 相似文献

In 2003, three proposals were being mediated through the planning system in the peri‐urban environment of St Andrews, Fife: a large housing development, a rail link, and a Green Belt. Using questionnaires and semi‐structured interviews with key stakeholders, we investigate the ways in which diverse conceptions of ‘the environment’ shaped public reactions to these proposals, and evaluate the fit between these and the respondents’ stated environmental perceptions. 98% of local residents surveyed describe themselves as ‘concerned about the environment’. However, large majorities conceive of the environment as a local rather than a global phenomenon, and regard it primarily in terms of personal benefits (such as landscape aesthetics or traffic considerations). By exploring the environmental perceptions in the light of the planning proposals, the study supports the contention that the ‘local environment’ is a socially constructed phenomenon which can be fashioned and re‐fashioned according to local perceptions of threats and opportunities. 相似文献

Anthropologists have persuasively made a case for critical ethnographic engagement with elites in recent years. The most significant risk of such an approach is that it may appear meaningless to powerful actors who claim they want to ‘do good’, such as impact investors and philanthropists. This article suggests that producing intermediary outputs targeted at these powerful actors first would generate the potential for solving contemporary problems, which, in turn, would help develop theory. 相似文献

An alabaster lid with a resinous accretion burnt or stuck next to the handle and on the base was uncovered in the Nabataean rest stop in Moyat Aawad (Moa) in the Arava valley in Israel. The analysis of this resin sample utilising GC‐MS revealed several types of compounds. The chemical analysis revealed compounds typically present in pine tar and plant lipid material (probably oil). The use of pine resin, tar and pitch derived from plant resins is documented in antiquity, not only as a sealant or caulking material but also as medicines, antiseptics and ritual balms. 相似文献
