AbstractGrounded in the main theoretical approaches to the study of electoral volatility, this article examines cross-regional variations in the levels of volatility for United Russia (UR) in Duma elections over the period 2003–2016, which are juxtaposed with the level of volatility for the Kremlin’s candidates in presidential elections. The main finding is that ‘regime type’ or, more precisely, ‘authoritarianism’ is the key explanatory variable. Stronger authoritarian rulers are able to control regional elites and ensure the best results for UR by exerting administrative pressure on voters. This reduces the level of volatility in support for UR. At the same time, economic and institutional explanations have a partial significance. Here, Duma elections differ from presidential elections, which demonstrate a much lower degree of volatility; in addition, economic factors appear insignificant. 相似文献

The article presents an application of the cost-benefit analysis to human sexual behavior. We suggest that an event or occasion which lowers the costs of sex – such as increasing free time, decreasing health risks of sexually transmitted diseases or lowering the probability of parenthood (or costs connected with parenthood) – usually leads to an increase in sexual activity. Although the reviewed studies concerning these effects confirm our predictions, findings are not robust, e.g. a vaccination against STDs does not always lead to an increase in sexual activity. In the conclusion, we make several socioeconomic recommendations resulting from the application of the economics of sex. 相似文献

Norms have been suggested as important characteristics of the social-ecological context for defending victimized peers, but little is known about the contribution of student perceived injunctive norms (regarding the appropriateness of defending) imposed by peers and teachers. To investigate the role of these norms in defending, a sample of 751 early adolescents (51% female; Mage at Time 1:13 years) was assessed at two time points. Defending, as measured by peer- and self-ratings, decreased slightly over a six-month timespan. Three-level models (with time, students, and classrooms as the levels) indicated that both individual- and classroom-level perceived peer injunctive norms (but not teacher injunctive norms) had positive effects on defending over time regardless of the source of the information on defending (peers or self). These findings support programs that encourage defending through peer norms. 相似文献

This study evaluates the role of tactical nuclear weapons (TNWs) for NATO today. Historically, TNWs fulfill five objectives. First, they provide a deterrent by denial capability. Second, TNWs serve to deter TNWs by other countries. Third, as the most ‘useable’ of nuclear weapons, they offer militaries solutions to a small target set of hardened targets. Fourth, they bridge the interface between nuclear and conventional forces, maintaining linkage up the ladder of escalation. Fifth, they serve as a powerful political symbol of an extended deterrent commitment. While the perception is that their utility for NATO in plausible European contingencies is low, we argue that there is variation in the political and military roles of TNWs. We submit that, in general, the first role has lost its significance but the other objectives remain relevant to NATO's present political circumstances, especially as a symbol of the transatlantic relationship and as a safeguard against Russian belligerence. Accordingly, TNWs remain a significant part of NATO's capabilities and should remain deployed in Europe. 相似文献

Abstract: Suicidal decapitation is seldom encountered in forensic medicine practice. This study reports the analysis of a suicide committed by a 31‐year‐old man with a self‐fabricated guillotine. The construction of the guillotine was very interesting and sophisticated. The guillotine‐like blade with additional weight was placed in a large metal frame. The movement of the blade was controlled by the frame rails. The steel blade was triggered by a tensioned rubber band after releasing the safety catch. The cause of death was immediate exsanguination after complete severance of the neck. The suicide motive was most likely emotional distress after the death of his father. In medico‐legal literature, there has been only one similar case of suicidal complete decapitation by a guillotine described. 相似文献
