Dramatic deterioration of Hellenistic-Roman limestone remains recently excavated at Dülük Baba Tepesi (Southern Turkey) has been observed following the cold, wet winter of 2011/2012. A conceptual model is presented to explain the dramatic deterioration in which case hardening develops and initially strengthens the stone against deterioration, but then makes it more prone to exfoliation and blistering. Data collected using non-destructive techniques (Equotip surface hardness tester and Karsten tube for water uptake) on F?rat and Gaziantep formation limestone time series excavated in 2005, 2007, and 2013 demonstrates the progress of case hardening and deterioration after excavation. In combination with meteorological data from Gaziantep weather station the results are used to test and revise the model taking into account non-linear and threshold effects. Future excavation and conservation efforts should take into account the often-complex interactions between post-excavation case hardening and extreme winter conditions which can cause catastrophic deterioration. 相似文献

ABSTRACT The increase in national earnings inequality in Great Britain over the last two decades has predominantly been a result of increasing earnings inequality within the regions of Great Britain, and not rising inequality between regions. However, there is a severe lack of empirical research exploring the evolution of earnings inequality within regions. This paper investigates the causes of rising within‐region inequality in Great Britain. It examines the changes that have taken place between 1976 and 1995, and regional quantile regressions are estimated to reveal those factors that have contributed to the rise in within‐region inequality. 相似文献

The concept of justice is central to a political activity such as planning. This is reflected in the initial influence of consequentialism, particularly utilitarian conceptualizations, in planning thought and more recently in the application of Rawls' notion of “justice as fairness” and Habermas' “discourse ethics”. However, contemporary normative planning theory has been vigorously criticized by studies which take as their starting point the material realities of planning practices. In this paper it is argued that notwithstanding the crucial contributions of Habermas and Rawls to political philosophy their constitutional level conceptualizations were never intended to be applied to the task of situated judgement associated with the highly contested decisions at the heart of the planning activity. Consequently, the issue for the planning community is not so much can the concepts of justice embodied in Rawls' “justice as fairness” or Habermas' “discourse ethics” be found in practice but could they ever. More generally it has been argued that the inevitable abstraction in liberal theories of justice comes so close to idealization that their ability to help individuals and societies to address the question of “what is to be done?” is seriously called in to doubt. This in turn has led to concern that an adequate account of justice should be able to link abstract principles to context sensitive judgement of particular cases. The paper explores some implications of these debates for the future development of theory and practice in planning. 相似文献

Water stress is becoming a permanent feature of life in Britain and other developed societies, and attempts to change ‘consumer behaviour’ are at the forefront of strategies for sustainability. This paper combines historical, geographical and sociological perspectives on the evolution of drought and water demand in modern England and Wales. Droughts have natural properties but their course, size and distribution is also the result of an interplay between governance, social norms and everyday practices. Focusing on seven significant droughts between 1893 and 2006, this article traces changing understandings of ‘normal’ water consumption and ‘rational’ demand and relates them to the evolving socio-technical management of water and identities of ‘the consumer’. We challenge the idea of a watershed between private supply (associated with passive ‘customers’) and public ownership (associated with active ‘citizens’). While private systems facilitated self-organised civic action more easily than public supply, the ideal of a citizen-contract blinded systems of public provision to the problem of expanding water use. An interdisciplinary analysis of droughts in the past offers lessons for the debate about sustainable consumption today. 相似文献

Guernsey and the other islands in its Bailiwick have been visited and settled by people arriving by sea for thousands of years. Guernsey Museum manages the display and interpretation of this maritime heritage and, in conjunction with the Receiver of Wreck, administers the legal protection of historic wreck. Over the last 25 years a considerable amount of research has been undertaken on many aspects of the islands' maritime past. Museum displays and media presentations have been made to disseminate information about the islands' maritime archaeology to the wider world. This paper will highlight the various aspects of maritime archaeology in Guernsey and illustrate how Guernsey Museum manages this rich archaeological resource.

For over five decades, Pictou Landing First Nation, a small Mi'kmaw community on the northern shore of Nova Scotia, has been told that the health of its community is not impacted by a pulp and paper mill pouring 85 million litres of effluent per day into a lagoon that was once a culturally significant place known as “A'se'k,” and which borders the community. Based on lived experience, the community knows otherwise. Despite countless government‐ and industry‐sponsored studies indicating the mill's pollutants are merely “nuisance” impacts and harmless, the community's concerns have not gone away. Using a “Piktukowaq” (Mi'kmaw) environmental health research framework to guide the interpretation of oral histories coming from the Knowledge Holders in Pictou Landing First Nation, we convey the deep, health‐enhancing relationship with A'se'k that the Piktukowaq enjoyed before it was destroyed, and the health suppression that has occurred since then. Conducting the research using a culturally relevant place‐based interpretive framework has demonstrated the absolute necessity of this kind of approach where Indigenous communities are concerned, particularly those facing health impacts vis‐à‐vis land displacement and environmental dispossession. 相似文献

Much interest-group analysis assumes that producer-group pressures are especially influential. Sometimes business interests conflict; in that case, which producer groups will be most influential? Using data from 54 state telephone rate cases, this paper explores the relative influence of several different intervener types. Estimates indicate that influencing outcomes depends on credible information rather than other resources, and also that business interest groups cannot all be considered homogenous. Some implications for the Telecommunications Act of 1996 are drawn. 相似文献

New evidence is emerging to suggest that climate change mobility is giving effect to changing forms of island identity among Tuvaluans and i-Kiribati. This nascent shift prompts a number of questions addressed in this paper. What, for example, does climate change migration mean for island identity and its geographic performance? How does the spatialization of identity inform shared experiences of climate change, and how does identity assist in the formation of shared positions from which to advocate for change? Drawing on discourses of sedentarism and mobilization among Tuvaluan and i-Kiribati, we explore performances of identity related to climate change being fashioned and refashioned in different contexts. 相似文献
