I explore asymmetric equilibria in a Tullock contest of heterogeneous players in the case when the players’ heterogeneity is weak, and the effort optimization problem can be analyzed in the linear approximation. With increasing discriminatory power of the contest, players sequentially drop out. The corresponding threshold values of the discriminatory power are related to those identified earlier for a Tullock contest of identical players. Weak heterogeneity, however, is sufficient to make the players’ behavior strongly asymmetric and qualitatively alter the structure of the equilibria as compared to the homogeneous case. 相似文献

Both China and Russia have undergone dramatic changes in the last 20 years. The Chinese elite have engaged in the changes with the preservation of the repressive aspects of Communist regime. This ensures stability and lead to the rise of China's economy. Russia dismantled the Communist regime with its repressive/controlling aspect and this lead to Russia's steady decline. At the same time Russia could express revival if it would follow the Chinese way. 相似文献

The articles in this issue of Russian Politics and Law examine the role of religion in state-society relations in Russia, with a specific focus on the Russian Orthodox Church. They highlight the role of the Church in modern Russian society and its relationship with the state, showing that as the relationship between Church and state has become closer, hopes that Patriarch Kirill would rejuvenate the Church have proved largely unfounded. 相似文献

Difficulties in the localization of bodies of homicidal or drowning victims in natural water result in their submergence for weeks if not months. Water insects and microbes drastically change the body's appearance, which significantly changes the determination of a victim's identity. DNA analysis is commonly used for identifying the decedent; however, this PCR-based approach is time-consuming and destructive of the evidence. Considering that nearly half of the people in the world dye their hair with a variety of permanent and semi-permanent dyes, one can expect that confirmatory identification of dyes on the body's hair can be used to shed light on the victim's identity. A growing body of evidence suggests that surface-enhanced Raman spectroscopy (SERS) can be used to detect and identify hair dyes. In this study, we investigated the extent to which SERS could be used to detect black and blue, permanent and semi-permanent dyes on hair submerged in hypolimnion water for up to twelve weeks. We found that SERS enabled 100% accurate identification of analyzed dyes on hair submerged in hypolimnion water for up to 8 weeks, whereas, on average, 87% accurate identification of the hair dyes could be achieved on hair exposed for 10 weeks and 50% for hair exposed 12 weeks in hypolimnion water. We also found that the aqueous environment caused progressive fading of some dyes, whereas other dyes showed substantial spectral transformations after prolonged submergence. Finally, we found that changes in the intensity of vibrational bands of dyes could be used to predict the duration of submergence of colored hair in hypolimnion water. 相似文献

Alexander Dugin, influential Russian geo-politician and proponent of Eurasianism, regards Russia as a heartland state that should engage in a web of alliances with various Eurasian powers to confront Russia's natural enemy, the US. While Eurasianism has been quite popular in the late Yeltsin era and Putin regime, it is important for other reasons as well. It demonstrates that, in the wake of the Cold War, the most unexpected combinations could happen. 相似文献
