Political scientists examine Vladimir Putin's efforts to ensure political control within a regime structure that is formally democratic. Methods for managing factional infighting, concentrating political resources in the "party of power," United Russia, and to limit electoral competition are specified. A Monte Carlo electoral simulation leads to counter-intuitive conclusions about the impact of proportional-representation rules on electoral processes and outcomes. Conclusions are drawn about the effectiveness of efforts to institutionalize an authoritarian regime in which shared power is vested in a hegemonic party.  相似文献

In this article, the author deals with the issue of life imprisonment without parole. Life imprisonment represents a new type of penalty in Serbian criminal law, in addition to standard imprisonment. The present state of the Serbian criminal legislation provides the possibility of parole for most criminal offences after 27 years of imprisonment served, while simultaneously explicitly prohibiting the possibility of parole for certain offences. The author elaborates the judgments of the European Court of Human Rights regarding life imprisonment, emphasizing rehabilitation as the primary goal of criminal sanctions. After that, the author explains the legislative solutions outlined in the Criminal Code of Republic of Serbia. Through the analysis of the crucial provisions of the Criminal Code, as well as other important and relevant laws, the author points out the shortcomings of the existing regulations in Serbia regarding life imprisonment, which flagrantly threatens to violate the offenders’ human rights.

ABSTRACT: Pontomedullary lacerations (PMLs) have often been reported in car occupants and pedestrians, are less frequently described in motorcyclists, and are very rarely described in bicyclists. The aim of this study was to determine the frequency of brainstem PMLs among fatally injured motorcyclists and bicyclists as well as the frequency of concomitant cranial, facial, and cervical spine injuries in such cases. A possible underlying mechanism of PML in fatally injured motorcyclists and bicyclists might thus be established. Of 443 cases of fatally injured motorcyclists and bicyclists, a sample of 381 cases of fatally injured motorcyclists and bicyclists with head injury of Abbreviated Injury Scale score of 3 or greater was formed and further analyzed. This group was composed of 345 men and 36 women. The average age was 48.8 ± 20.8 years (range, 15-99 years). In the analyzed sample group, there were 158 motorcyclists and 223 bicyclists. Partial PMLs were present in 44 cases (12%) within the sample of 381 head injuries, which breaks down to 40 men and 4 women. In our study, the impact area on the head and the specific skull base fracture type were good predictors of either PML occurrence or absence (B = -2.036, Wald = 161.312, P < 0.01, for the whole model). Impact to the chin, with or without a skull base fracture, most often led to this fatal injury due to impact force transmission, either through jawbone or vertebral column. Also, lateral head impact, the most frequent in bicyclists, with subsequent hinge fracture, PML, and frontoposterior hyperextension of the head that is associated with upper spine fracture, could be possible mechanisms of brainstem injury in fatally injured motorcyclists or bicyclists. Our study showed that the jawbone, as well as other facial bones, could act as shock absorbers, and their fracture could diminish energy transfer toward the skull and protect the brain and brainstem from injury.  相似文献

Anomaly in the anterior papillary muscle (APM) is known to cause left ventricle outflow tract (LVOT) obstruction, and this rare congenital condition could be a cause of sudden cardiac death. This anomaly and its hemodynamic effects is similar to valvular heart disease. In our two described cases, in which cause of death was, respectively, hypertrophic cardiomyopathy and suicide by hanging, the cephalad portion of the left APM was inserted directly into the ventricular surface of the anterior mitral leaflet and chordae tendineae were absent in the area of the direct anomalous muscle insertion; the aberrant papillary muscle was very large and showed an exaggerated anterior displacement within the left ventricular cavity. The described anomaly is a cause of LVOT obstruction. This condition is considered to be rare, although incidence estimates do not exist. In the absence of other possible causes, this finding may indicate arrhythmia as being the immediate cause of death.  相似文献
