The changes, sometimes dramatic, in the size and structure of the ethnic groups of the Russian Federation (RF) raise questions about their possible futures. The paper presents simulations of how ethnic groups of the RF could develop in the future and discusses the demographic aspects of the predicted changes. The simulations cover a 25-year period, from 1 January 2011 to 1 January 2036 and were prepared for the 22 most numerous ethnic groups using a multistate cohort-component population dynamics model. To prepare the assumptions for the simulations, ethnicity-specific data (no longer collected) on fertility, mortality, and international migration were used. The results indicate that in the coming 20 years Russia will face numerous challenges related to the changes in the size, age structure, and ethnic composition of its population. The population of the RF will age and, except in the “Modernization” scenario, will shrink. Non-Slavic and Muslim populations will increase their share in the total population at the expense of Slavic and Orthodox ethnic groups and will age more slowly.  相似文献

This article reviews the ways in which class, status, social mobility and their cultural ramifications have been considered (or failed to be considered) in recent ethnographic studies of the Islamic Republic of Iran. It argues against the trend of privileging “resistance” to an oppressive state as a theoretical frame for documenting social phenomena in Iran: lifestyles and consumption patterns cannot be interpreted merely as signs of political rebellion because they are endowed with symbolic value as status attributes in a society whose class configurations are shifting. I present a number of sources and concepts that help to rethink these phenomena, and show how the experience of Afghan refugees living on the margins of Iranian cities illuminates both the opportunities and constraints created by the Islamic Republic's uneasy mix of political Islam, populism and neoliberalism. A focus on aspiration to upward mobility becomes a useful analytical lens that allows us to sidestep reductive dichotomies such as tradition/modernity or religion/secularism that are in practice blurred by its very pursuit.  相似文献

This study presents the preliminary results of investigation of the lime mortars and plasters from archaeological excavations in Hippos (Israel), using Electron Paramagnetic Resonance (EPR) spectroscopy. The research was conducted in order to characterize the building material and its reaction to ionizing radiation. The ancient settlement Hippos, situated on the east shore of the Sea of Galilee, functioned from the 3rd cent. BC until it was destroyed by the earthquake in 749 AD. Lime mortars and plasters show carbonate and locally gypsum character of binder and different kind of aggregate. Samples were γ-irradiated and measured using X-band EPR spectrometer. Computer Resolution Enhancement Method was applied to the complex spectra. Some of the γ-induced EPR signals were attributed to CO2 ? and CO3 3? paramagnetic centres. Exponential growth of the dose response curve above 1 kGy and saturation for doses above 20 kGy was observed. For doses lower than 1 kGy the dose response curve has a linear character. The presence of γ-sensitive carbonate paramagnetic centres could indicate that, after further studies, well-chosen samples of mortars and plasters might be suitable for EPR dating, assuming the centres have been sufficiently bleached during the manufacturing process.  相似文献
