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

Environmental Impact Assessments (EIAs) are the pre‐project standard for outlining potential environmental and social risks related to large‐scale mining. Incomplete or disingenuous EIAs mask the potential social, environmental and economic impacts of large projects. To examine the possible misrepresentation of project risks, this article analyses a set of EIAs for the proposed Niyamgiri mine and related Lanjigarh refinery and refinery expansion in Orissa, India. In contrast to their promises of development benefits, it is argued that the project assessments fail to acknowledge the substantial social impacts for project‐affected persons as some face displacement, livelihood change, marginalization and a loss of natural resources. The issues raised here are not unique to these cases, but are representative of a flawed system in which environmental clearance is granted for projects with misleading or mis‐assessed EIAs. This article questions the validation of ‘development’ projects via EIAs which do not thoroughly estimate the social risks and costs of projects. 相似文献

The Scottish writer Robert Louis Stevenson visited the Hawaiian Islands from January–June 1889, in the middle of one of the most turbulent periods in its history. While staying on the islands he became associated with King Kalakaua's royalist faction, which was then involved in a struggle for power against the Reform Party, whose members were responsible for leading Hawai‘i first to republican rule (1893) and then to American takeover in 1898. This article examines Stevenson's encounter with the Reverend Sereno Bishop, author of a pamphlet enquiring into the causes of indigenous depopulation, within the context of significant social and political change on the islands. While evidencing the growing politicisation of Stevenson's later years, his experience also bears witness to the development of Americanism in the Reform Party, who prepared the way for annexation by aligning themselves ideologically with sympathetic elements in the United States. 相似文献

Abstract The concept of ‘social exclusion’ has become central to the UK government's political philosophy. The need to combat the causes and deal with the symptoms of ‘social exclusion’ has become vital to many policy initiatives. The use of heritage resources to help deal with social problems has been practised since the early years of the 19th century and can provide a community with a focus, identity and pride as well as making a contribution to regional economies. This paper traces the use of heritage resources in community regeneration programmes and demonstrates their lack of objectives and unplanned nature. A holistic multi‐agency approach is advocated to tackle social exclusion, with heritage playing a central role. Finally, the paper calls for research which will clarify the contribution that heritage resources can make and identify a framework within which heritage can realise its potential to build communities. 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
