In one of the first quantitative designs, we explore the impact of both legalisation and flexibility on regime effectiveness, using data on international environmental institutions. One of the main implications is that ‘precision’ is an important determinant of regime performance. If the rule and norm system is well defined, well understood and clear, then a regime tends to be more effective in addressing an environmental problem. We do not find evidence, however, that ‘hard law’ is more effective than ‘soft law’ or that delegation mechanisms may be relevant. Second, flexibility in the regime structure increases regime performance – regular instead of subsidiary bodies enhance flexibility and thus have a positive effect on a regime's environmental problem management. Flexibility in states' agenda setting power, membership and decision making do not seem to have a crucial influence, though. 相似文献

Optically stimulated luminescence dating of young fluvial deposits of the Middle Elbe River Flood Plains using different age models 总被引:1,自引:0,他引:1

In the last few decades optically stimulated luminescence (OSL) dating has become an important tool in geochronological studies. The great advantage of the method, i.e. dating the depositional age of sediments directly, can be impaired by incomplete bleaching of grains. This can result in a scattered distribution of equivalent doses (DE), leading to incorrect estimation of the depositional age. Thoroughly tested protocols as well as good data analysis with adequate statistical methods are important to overcome this problem. In this study, samples from young fluvial sand and flood plain deposits from the Elbe River in northern Germany were investigated to compare its depositional ages from different age models with well-known historical dates. Coarse grain quartz (100–200 μm and 150–250 μm) and polymineral fine grains (4–11 μm) were dated using the single aliquot regenerative (SAR) dose protocol. The paleodose (DP) was calculated from the DE data set using different approaches. Results were compared with the development of the Elbe River, which is well-documented by historical records and maps covering the last 1,000 years. Depending on the statistical approach it can be demonstrated that depositional ages significantly differ from the most likely depositional age. For the investigated coarse grain quartz samples all ages calculated from the MAM-3UL, including their uncertainties, are within the historical documented age. Results of the polymineral fine grain samples are overestimating the historically documented depositional age, indicating undetectable incomplete bleaching. This study shows the importance of using an adequate statistical approach to calculate reliable OSL ages from fluvial sediments. 相似文献

This article provides a study of political positions concerning the role of religion in modern society in Sweden between 1920 and 1939. It aims to increase understanding of the Swedish secularization path, with special emphasis on issues related to heritage and national identity, by comparing the dominant perspectives on these issues in the Church of Sweden and in the Social Democratic Party during that period. It addresses how these positions have influenced policies during the period, as well as some of their implications for later path dependence. It explores relations between religious issues and the concept of national heritage, as well as how the fact that both were at that time commonly seen as legitimate tasks of the state came to influence the development of Swedish church-and-state relations and heritage policies. Special attention is given to the positions of the Young Church Movement, a movement within the Church emphasizing its role as a national church with a central position in national identity, as well as to the views of Arthur Engberg, the anti-clerical Social Democratic government minister responsible for church, education, and culture in the 1930s. 相似文献

In Germany and the Netherlands spatial information about the social structure of the inhabitants is used for the coordination of financial and human resources in the local school-system. The aim is to reduce educational inequalities by taking the social context of the schools into account. The article explains two approaches. In North Rhine-Westphalia (Germany) a so called Sozialindex is used to distribute additional teachers to municipalities with difficult social surroundings. The Dutch government uses an instrument to give each pupil a weight (gewichtenregeling) depending on the specific educational background. Combined with an evaluation of the school location an additional budget, if necessary, will be payed. 相似文献

The reviewed books comprise an emerging ethnographic literature on endangered language documentation and revitalization in Native North America. Language loss and preservation are pressing concerns for tribal communities, galvanizing activists and researchers to develop classroom curricula and literacy traditions in hopes of producing new speakers. While the reviewed books show that this goal often goes unrealized, we nevertheless read them as grounds for optimism. Even if language revitalization rarely increases the everyday use of particular lexical and grammatical codes, it may succeed in accomplishing another important goal: facilitating indigenous communities’ efforts to create for themselves more meaningful contemporary cultures. 相似文献
