This issue of Russian Politics and Law concludes our series reviewing the role of religion in state-society relations in the former Soviet Union. This issue examines the role of the Church in Belarus and provides several analytical perspectives on the series' findings. The analytical findings highlight the distinction between the extent of popular identification with Orthodoxy and levels of active practice and belief among the population. 相似文献

Confirmatory identification of hair colorants can be used to establish a connection between a suspect and the crime science or demonstrate the absence of such connections. A growing body of evidence shows that surface-enhanced Raman spectroscopy (SERS) could be a confirmatory, minimally destructive, and fully noninvasive analysis of hair colorants. In SERS, a signal that provide the information about the chemical structure of both permanent and semipermanent dyes present on hair is enhanced by a million-fold using noble metal nanostructures. However, it is unclear whether the information of hair colorants can be revealed if hair was contaminated or exposed to harsh environments such as sunlight and heat. In this work, we determine the effect of a short- and long-term heat exposure on SERS-based analysis of hair colored with blue and red permanent and semipermanent dyes. We found that short and especially long-term heat exposure at 220°C could alter chemical structure, and consequently SERS spectra, of permanent and semipermanent colorants. This thermal degradation of permanent dyes complicates their direct identification using SERS. We also found that partial least squares discriminant analysis can be used to overcome this issue allowing for highly accurate identification of both permanent and semipermanent dyes on colored hair that was exposed to 220°C for 6–12 min. These results show that heat exposure of colored hair should be strongly considered upon their SERS-based examination to avoid both false positive or false negative identification of chemical dyes. 相似文献

This study contributes to the debate on the role of nonnuclear (conventional) deterrence in international security by examining the Israeli practice of this strategy. By analyzing a case outside of Western strategic thought, which traditionally has dominated deterrence theory, it demonstrates how strategic thinking evolves differently in various ideational realms. The article highlights the impact of strategic culture on the Israeli conceptualization of deterrence, explores its deficits, and yields lessons for theoreticians and practitioners from the challenges of intra-war coercion operations. The study introduces the innovative term “culminating point of deterrence,” calls for improving analytical techniques for deterrence evaluation, claims that successful conventional deterrence perpetuates political conflict, stimulates the adversary's dangerous innovations, and argues for a tailored approach not only for formulating deterrence strategy, but also for exploring deterrence policies of different actors. The findings of the study are applicable beyond the Israeli case and are relevant to actors utilizing coercion strategies. 相似文献

From the moment when wide spread of large scale assessments in sociology and economics began, the most commonly used indicators of peoples’ qualifications are the number of years spent in education and the possession of a high school/college/university diploma. But what if these formal indicators are unreliable under certain conditions and do not reflect actual literacy and competency of people? This article, drawing on data from the Programme for the International Assessment of Adult Competencies (PIAAC), questions accuracy of the basic educational indicators in Russia. There is a linear relationship between the possession of a formal graduation diploma and the measurement of PIAAC literacy of the able-bodied population in OECD countries, including the Eastern European ones. However, the analysis shows that in Russia there is an inconsistency between literacy and formal educational status. This fact in itself casts doubt on the effectiveness of formal education indicators in Russia. The social implications resulting from this inconsistency become apparent through an international comparison of research results. These ill effects have been documented in the areas of employment, education and social reproduction and in the social self-awareness of the Russian people. 相似文献
