为了开展环境因素对有机质材料色牢度影响的研究,及寻找不同的文物陈列展览与藏品保存所适宜的环境,必需了解文物环境的质量状况,探讨环境因素对文物造成的影响及变化规律。为此,选择故宫博物院有代表性的文物陈列展览与藏品保存的环境为试验场所,对该试验场所环境温湿度进行检测分析,同时在该环境中摆放试验样品,对试验样品的颜色变化进行不定期的检测。经过试验样品色牢度的检测和试验数据的整理分析,得出了相同环境下,丝织品试验样品色牢度变化比绘画颜料色牢度的变化大;三种不同温湿度的环境,对丝织品试验样品色牢度变化影响也不相同,其中,红色样品变化最敏感。相对绘画颜料,不同环境温湿度变化对其造成的影响较小。  相似文献

由于地方各级政府在构建和谐社会的过程中发挥着主导作用,必`须在制度供给方面作出相应的变革以适应构建和谐社会的要求。即由效率主义向正义内核转变、由追求经济收益最大化向最大限度地实现公共利益转变、由非制度化和非规范化的制度供给方式向制度化和规范化的供给方式转变。  相似文献

For every successful megaproject, there are dozens that have failed to launch, left as paper remains, imaginary geographies of development and enterprise. Although most scholarly attention focuses understandably on the projects which have been built, we need to look again at those projects that have been put aside, rejected, and cancelled. Failed projects produce unbuilt environments, and these have their own peculiar effects. This paper interrogates the planning, development, debate and abandonment of a massive infrastructure project in a remote area of northwest British Columbia. BC Hydro’s attempt to build five dams on the Stikine and Iskut Rivers in the late 1970s and early 1980s never materialized. However, in the ten-year attempt to justify the economic and environmental cost of the proposed dams, BC Hydro commissioned several dozen large resource inventories and analyses of biophysical, cultural, socioeconomic and hydrological data in the Stikine Watershed, where this information had been largely absent. In doing so, BC Hydro circumscribed the terms of the debate around dam construction, framed the constituents of the debate and reordered knowledge about the region. Locals and other interested parties began to engage with the river differently. I argue that the apparatuses of scientific, engineering and technological engagement that were implemented by BC Hydro resulted in both material and discursive changes to nature in the Stikine. I develop the concept of ‘unbuilt environments’ to understand the changes that emerge in the wake of failed infrastructure projects.  相似文献

This article tests capture theory by analyzing voting behavior on U.S. Regional Fishery Management Councils. Some seats on the councils are reserved for state and federal agency representatives; others, for political appointees. The political appointees primarily represent special interests (specifically, commercial and recreational fishing interests); a smaller number of appointees represent public interests. We use logistic regression to model the vote of state and federal agency representatives on the councils as a function of the votes of commercial interests, recreational interests, and public interests. We find evidence that some state agencies are captured by special interests from their states, but not systematic evidence across all states. We find that state agency representatives voted with commercial interests from their own state in five of the sixteen states in our sample; with recreational interests in three states; and with both special interests in two states. These ten states support the capture hypothesis; the other six states do not. We find no evidence that federal agencies were captured on the councils. We conclude that the gubernatorial‐driven appointment process leads to capture at the state level by promoting voting blocs among state agency representatives and special interests from those states. Federal agency representatives, by contrast, are better able to maintain their distance from state‐level politics on the councils, and thereby enhance their ability to vote independently on fishery management measures.  相似文献

This study of Middle Palaeolithic assemblages from the Rhone Valley, in the South-East of France, increases our understanding of Neanderthal subsistence strategies and modes of territorial organisation by comparing a wide corpus of human occupations in limited chronological and geographical frameworks. The Neanderthal occupation modes may be examined using sites located in a reduced area, linking medium-altitude territories (Massif Central and the Alpine foothills) to the Rhone corridor. Through the combined analysis of the occupation levels of ten sites, all dated to between Marine Isotopic Stage (MIS) 7 and the beginning of MIS 3, we identify three types of occupation durations: (1) type 1 as long-term residential camps, (2) type 2 as short-term regular hunting camps and (3) type 3 as brief stopover camps. We discuss this variability of habitat types according to various parameters: site age, technical behaviour, environmental conditions, and site localisation and occupation seasons. The aim is to discern the underlying motivations behind Neanderthal group mobility. One of the main features of the Rhone Valley area is the great homogeneity of behaviours reflected within the sequences. This homogeneity, linked to the variability of the site occupations, supports the hypothesis of Neanderthal groups anticipating their land use requirements, and furthermore suggests that another type of circulating model was used in this area.  相似文献

1992年联合国环境与发展大会评析   总被引:1,自引:0,他引:1  
联合国环境与发展大会是继1972年联合国人类环境大会后国际环境保护史上的又一个里程碑事件。大会的召开与20世纪80年代后期世界范围的环保主义高潮有着直接的联系。在预备会议和正式会议上,南北国家代表围绕全球可持续发展的几个主要焦点议题产生了分歧并展开了激烈的辩论。会议取得的主要成果表现在两个方面:一是确立了世界各国在可持续发展和国际合作的一般性原则。二是制订了可持续发展和国际合作的战略措施。  相似文献

Environmental violence and crises of legitimacy in New Caledonia   总被引:1,自引:0,他引:1  
This paper addresses the question of what factors besides resource abundance or scarcity play crucial roles in conditioning resource-related violent conflict, by investigating the responses of residents of villages near a mining project in New Caledonia to Rhéébù Nùù, an indigenous environmental protest group. An overlooked and yet crucial factor in local support for Rhéébù Nùù was a lack of faith in the government and, more fundamentally, in the democratic system through which representatives were elected. Instead, villagers put their faith in a revitalization of customary authority. Thus, environmental violence is not driven simply by resource abundance or scarcity; in this instance, it masked a crisis of political legitimacy, grounded in a history of opposition to the colonial power. This leads to the paper's second question: What constitutes a basis for political legitimacy, and how is this legitimacy – and its contestation – mediated by socio-cultural concerns? This study suggests that legitimacy requires the achievement of three elements: representation of people's interests, coherence with cultural identity, and popular acceptance of methods used to exert power. The protest group was more successful at achieving these elements of legitimacy, and thus the support of the local residents, than was either the government or the mining company. However, not all community members felt that Rhéébù Nùù indeed had the support of customary authority, and many disagreed with the group's violent tactics. Thus, protest groups may be subject to the same criteria of legitimacy as the governments or other bodies that they oppose.  相似文献
