Complex suicides are defined as suicides using more than one method, which may sometimes suggest homicide. We present the case of a 27-year-old man who killed himself by using four different methods. The man was known as a loner and sufferd from bipolar psychosis. An eyewitness saw him afire and falling out of a window on the 4th floor of a hotel. He was wearing a judo dress with the belt wound twice around his neck. He died in a hospital about two hours later. The autopsy showed signs of neck compression typical of (self)-strangulation, several stab and cut wounds in the thoracic and abdominal region from sharp force, extensive first- to third-degree burns caused by the effect of heat, contusions of internal organs, serial rib fractures and several bone fractures of the extremities as signs of blunt force. The CO-Hb value in the blood amounted to 7%; the other toxicological tests were negative. Death was found to be due to exsanguination from a deep stab wound in the abdomen and multiple trauma caused by the fall from a great height in the course of a suicide. Homicide could be excluded due to the circumstances of the case, which demonstrated again that both the medical findings and the investigation results of the police are indispensable for the differentiation between suicide and homicide.  相似文献

Abstract: Mitochondrial DNA (mtDNA) analysis has proved useful for forensic identification especially in cases where nuclear DNA is not available, such as with hair evidence. Heteroplasmy, the presence of more than one type of mtDNA in one individual, is a common situation often reported in the first and second mtDNA hypervariable regions (HV1/HV2), particularly in hair samples. However, there is no data about heteroplasmy frequency in the third mtDNA hypervariable region (HV3). To investigate possible heteroplasmy hotspots, HV3 from hair and blood samples of 100 individuals were sequenced and compared. No point heteroplasmy was observed, but length heteroplasmy was, both in C‐stretch and CA repeat. To observe which CA “alleles” were present in each tissue, PCR products were cloned and re‐sequenced. However, no variation among CA alleles was observed. Regarding forensic practice, we conclude that point heteroplasmy in HV3 is not as frequent as in the HV1/HV2.  相似文献

Abstract

This article looks at Russia’s exercise of power politics in Ukraine and Syria as a way of improving its international status. Russia’s recent willingness to use power and coercion is theoretically counterintuitive as it appears to be in dissonance with the prevalent characterisation of the country as a status-overachieving inconsistent power. We argue that this behaviour is not the result of a consistent weighing of status against capabilities, but rather reflective of both internal and external dynamics. We analyse issues of identity, opportunity and costs as factors that influence Russian foreign action, showing that power politics will not solve Russia’s status-inconsistency problem in the long run.  相似文献

This research examined the challenges, enablers and outcomes of organisation transformation in Philippine local governments. We combined a multi-case study research design and backward mapping approach in collecting and analysing narratives from 55 leaders in 9 Filipino local government units (LGUs) that have successfully undergone transformation. Results show that the transformations of the LGUs appear to have been catalysed by three interrelated elements: vision, LGU leadership and citizen engagement. The transformation in the local governments concentrated on multiple foci of reform including structure and systems improvement, culture change, human-resource development as well as policy and programme development. This holistic approach enabled the transformation of bureaucratic and unprofessional government service to transparent, professional and efficient public service that engendered pride, transparency and social equity. Implications of the proposed model for transforming LGUs and in developing LGU leaders for good governance are discussed.  相似文献

Research has shown that early maturation is related to problematic alcohol use, yet the differential effect of early pubertal timing (i.e., younger age at menarche) on the onset of alcohol use and subsequent level of alcohol use has rarely been examined. This distinction is relevant, as younger age at menarche can have differential effects on these outcomes, which in turn can have long-lasting effects. Therefore, the present study examined the relationship between age at menarche and adolescent alcohol use among girls, hereby distinguishing between onset and level of alcohol use. In addition, the moderating effects of alcohol-specific rules, child disclosure and class gender composition were examined. Participants were 430 girls from a Dutch four-wave survey, with a mean age of 12.17 years (SD = 0.50) at the beginning of the study. Results showed that the probability of onset of alcohol use was increased by younger age at menarche, but only when girls were younger than 15. Moderation analyses showed that younger age at menarche increased the risk of alcohol onset only in low risk girls (with high levels of alcohol-specific rules and in classes with a high percentage of girls). Once adolescent girls started drinking alcohol, younger age at menarche was associated positively with alcohol consumption only for girls in classes with a moderate to high percentage of girls. These findings confirm that younger age at menarche is a risk factor for the onset of alcohol use, but strongly suggest that this effect is strongest for girls having restrictive alcohol-specific rules and in classes with a high percentage of girls. Possibly, in the absence of social factors that “push” to alcohol use, biological factors (like age at menarche) become more important. Another possibility is that adolescent girls start drinking alcohol to oppose their parents if they set too strict alcohol-specific rules.  相似文献

We explore the evolution of the Kremlin’s election control strategy in response to the reintroduction of gubernatorial elections in 2012. Our analysis focuses on the evolution of four tools used to engineer electoral competition: auxiliary institutions, subnational punishment regimes, ballot construction, and turnout manipulation. We argue that election managers deploy these mechanisms to maximise victories for state-sponsored candidates while minimising the possibility for post-election protest. The analysis demonstrates that electoral manipulation presents conflicting incentives for the Kremlin and its regional officials. It also shows the critical role that Russia’s systemic opposition plays in the electoral management system and regime stability.  相似文献

The proximity of Ukraine’s Orange Revolution (2004) andEuromaidan Revolution (2014) provides an opportunity to considerwhy some individuals remain active across protest cycles whileothers defect. Many social movement scholars explain differentialparticipation in terms of micro-structural, biographical, or cognitivefactors. Others rely on rational choice theories of collective actionbased on coordination. Testing competing explanations arecomplicated because the variables included in structural andagency-based models are often the same, although the underlyingcausal mechanisms are different. In this article, I argue that thekey to understanding the role of agency and structure in protestparticipation is to relax strong assumptions about the unified natureof society and consider the multiple paths to participation. Thisapproach suggests that both structural and agency-based causalmechanisms can influence political engagement depending onindividual experiences, identities, and perceptions of events.  相似文献
