The current Bronze Age settlement model for the middle and upper Great Ouse valley is based on the distribution of ring ditches from aerial photography, their excavation and the occurrence of stray finds. This settlement study, which is part of a broader survey programme, has initially concentrated on obtaining flint distribution patterns by field walking to see in what ways these could amplify and perhaps solve the problems posed by present evidence. It was also intended to assess its value as a tool for problem solving in the context of landscape archaeology and settlement studies. Although the areas examined were small and selective, the flint distribution patterns, when considered with other evidence suggested that ring ditches were part of complex and extensive settlement locations. However it was evident that the ring ditches were set away from the main habitation foci.  相似文献

Abstract

A survey was carried out of the stone types of the south porch of Gloucester Cathedral, repaired in 1992. Although very little of the medieval fabric remained, much information emerged about the types of stone used in the 19th century, and the building materials of the original south porch could also be established. The work formed the basis of most present knowledge about the past use of stone at Gloucester Cathedral.  相似文献

Abstract

In the 25 years since the dissolution of the Soviet Union, sweeping political, economic, and social changes have profoundly influenced environmental protection in Russia, the world’s largest country and one of global importance with respect to natural resources, biodiversity conservation, wilderness preservation, and climate change mitigation. This paper reviews the state of the environment by assessing post-Soviet era changes to legislation, government regulatory institutions, and civil society. A gulf exists between Russia’s formal environmental laws and state agency capacity and interest in enforcing them. This stems, in part, from repeated bureaucratic reorganizations that have progressively eroded environmental institutions. The Russian environmental movement, which blossomed during Gorbachev’s reforms in the late 1980s, struggled in the 1990s to mobilize the broader public due to economic hardship and political instability. Since then, the Putin administration has labeled many environmental groups “anti-Russian” and used aggressive tactics such as raiding NGO offices, intimidating journalists, and instituting severe legislative measures to quash advocacy and dissent. Post-Soviet environmental successes have been relatively few, with expansion of the protected area system and forest certification notable exceptions. These successes can partially be attributed to efforts by large environmental organizations, but expansion of certification and corporate social responsibility is also tied to Russian business interests dependent on natural resource export to global markets increasingly sensitive to environmental concerns. The paper concludes by illustrating how corruption, poor enforcement, and the muzzling of civil society render the state incapable of resolving arguably its most significant environmental challenge: illegal and unregulated resource use.  相似文献
