Next year marks a quarter century since the end of the Soviet Union. How has power evolved in the region? What might the future hold? What are the implications for the West? Three important works illuminate these questions from different angles. Henry Hale argues that (except for the Baltic states) post‐Soviet regimes are fundamentally similar to one another in being constituted by informal networks that dominate resources and institutions. They converge around, and compete for, influence with a powerful presidency that imposes selective rewards and punishments. Succession is the key weakness, and an unpopular lame duck leader invariably leads to upheaval. Karen Dawisha charts the rise of Vladimir Putin's network of friends and colleagues, and documents allegations of corruption and illegality. She shows how quickly this network, on gaining presidential power, revived state strength and undermined other networks. Peter Pomerantsev vividly portrays a society of simulations ruled by a deft and disorienting ‘post‐modern authoritarianism’. But as systemic popularity has declined this has given way to a harder, shriller anti‐western course, and ultimately to the annexation of Crimea. The future may see the international context play a greater role in regime evolution than before. The compelling anatomy of power laid bare in these three works points to growing tensions and flaws in patronal rule across the post‐Soviet space. 相似文献

One consequence of the expanding road network and its associated traffic is increased levels of traffic noise. While the hedonic literature has consistently found a negative relationship between real estate prices and noise levels, research in the United States has typically relied on crude measures of traffic noise. Here, we reduce the measurement error of traffic noise exposure through a detailed model of noise propagation over the landscape. We then estimate the hedonic relationship between noise and single family house prices using over 40,000 transactions throughout the St. Paul, Minnesota, urban area from 2005 to 2010. We implement spatially and temporally flexible local regression techniques and find significant nonstationarity in the hedonic function over time and space. 相似文献

AbstractIn many countries, rural areas have shown a new spatial-economic dynamics that have meant a contrast with the traditional urban-rural dichotomy. In particular, the need to use economic-ecological sustainability as a guiding principle for new rural development is a prominent feature. But how will rural areas, sometimes suffering from lack of economic development, peripheral positions and relatively low social well-being be able to face new challenges? Can they be attractive, innovative and developed (“hot spots”) while maintaining their sustainability and continuity? This question was the background in conducting our research. Hence, this study aims to answer this question in three steps, namely (i) offering a contemporary overview, (ii) identifying the critical factors for and (iii) developing a set of sustainable development scenarios. In order to reach our aims, we applied the so-called pentagon model and used multi-criteria analysis, namely regime analysis. The data and information deployed in this study were obtained from field surveys conducted in 60 European and 17 Turkish rural areas. The results show that future choices are different among rural users and between European and Turkish villages. European users seem more consistent about their future and their will while the will of Turkish villages are still more concentrated on economic development rather than sustainable development itself. 相似文献

A range of experiments were conducted in an attempt to create tar from the bark of Betula pubescens (downy birch) using an aceramic dry distillation process. Fire structures based on small pits and small kiln-like mounds were explored with a focus on fire intensities and differing burn times under field-based conditions. Heat penetration presented itself as an all-important factor, and the depth of the construction of the structures and features was considered to directly correlate to the impact of the heat. Single variable experiments confirmed that the necessary reducing atmosphere was achievable despite friable soil, but that heat would not penetrate a 50- to 80-mm-deep layer of grass turf. The evolution of structures from pits towards a raised type resulted in kiln-like structures which proved more successful. Though the experiments did not successfully produce tar as a finished product, they did lead to a better understanding of the dry distillation process of the established technology of birch bark tar extraction in aceramic societies. 相似文献

We studied the composition, colour chromaticity and form of application of red pigments in human bone samples from seven Classic period Lowland Maya sites. The samples were analysed by X‐ray diffraction, scanning electron microscopy (SEM) and X‐ray energy‐dispersive spectroscopy (EDS). Colour was measured using conventional colour identification standards (Munsell) and reflectance spectroscopy. Cinnabar and hematite were identified as the pigments used. We conclude that the reflectance method has advantages over conventional visual results, as it provides precise, objective and quantifiable optical data to distinguish the chromaticity, colour saturation and brightness of the pigments. 相似文献
