A 37-year-old Turkish woman was fatally injured by her 65-year-old Turkish husband with a stab to the cervical region. After her death he inflicted a deep cut to his own neck, which he survived thanks to immediate medical assistance. To the authors' knowledge this combination of a homicidal stab to the neck and a suicidal cut to the neck has not been described before. Kosher butchering, which is common in the couple's traditional cultural environment, is discussed as possible reason for the choice of the neck as site for applying sharp violence. It may have induced the perpetrator to choose this anatomical region.  相似文献

This study examines the experience of emerging adult immigrants, a group simultaneously attempting to navigate the developmental period of exploration and experimentation of emerging adulthood, together with the need for re-organization of the self, following immigration. In this study, in-depth interviews were conducted, with 41 emerging adult immigrants from the former Soviet Union in Israel and 42 non-immigrant Israeli emerging adults (all in the age group 21–25), on the subjects of sense of self, family relations, and age-appropriate tasks of emerging adulthood. Results showed that while immigrant emerging adults had a more disorganized sense of self, they also showed higher levels of both autonomy and relatedness in the relationship with their parents. Immigrant emerging adults had fewer social networks, yet more intimate relationships. Emerging adult immigrants' story was one of “relatedness” where level of self-organization was related to closeness, caring, and identification with parents, and closeness in both social and intimate relationships. In contrast, the non-immigrant emerging adults told about a process of “autonomy seeking” where a consolidated sense of self was related to more independent decision-making, emotional independence, and assertiveness in the relationship with parents. The findings of this study point to the complex and unique process that emerging adult immigrants undergo while coping with developmental tasks in their new environment.

This article analyzes some factors underlying the spread ofinsurgent violence in Africa. It focuses on the impact externalfactors have on power struggles on the continent. The firstof these is the unsteady support for democracy from Westerndonors, which has impeded more far-reaching domestic changesin much of Africa. Second are wider changes in the internationalsetting that dramatically enhanced the international standingof armed movements in the post-1989 period. The article arguesthat the interplay of both factors has induced would-be leadersto conquer state power by violent rather than non-violent means.This becomes particularly evident in regard to Western effortsto solve violent conflict through power-sharing agreements.The hypothesis is put forward that the institutionalizationof this practice for the sake of ‘peace’, i.e. providingrebels with a share of state power, has important demonstrationeffects across the continent. It creates an incentive structurewould-be leaders can seize upon by embarking on the insurgentpath as well. As a result, and irrespective of their effectivenessin any given case, power-sharing agreements may contribute tothe reproduction of insurgent violence.  相似文献

In the context of the European project ROSITA, the Institut of Legal Medicine Homburg/Saar has co-operated with the Saarland traffic police in order to assess different roadside drug tests for their functionality and reliability in traffic controls, and for their analytical force of evidence. In 254 cases within the time period from June 1999 to December 1999, police officers performed a (voluntary) roadside drug testing in saliva/sweat, or urine, to confirm or refute their initial suspicion that a driver had used drugs. Whereas in 45 cases the tests gave negative results (which were confirmed by lab urinalysis), in 209 cases the police officers ordered blood samples after a positive outcome of the tests.In 203 of the 209 positive cases, the results could be confirmed by GC/MS analysis. Regarding the prevalence of used drugs, a single consumption was found in 156 cases (113 cannabis, 38 amphetamines/methamphetamines, three opiates, two cocaine), and a consumption of two drugs was found in 44 cases (34 cannabis+amphetamines/methamphetamines, five cannabis+opiates, three cannabis + cocaine, two cocaine+amphetamines/methamphetamines). In three cases, multi-consumption was found.In six cases, the performed tests gave an incorrect prediction to the police officer at the roadside.The roadside tests gave 97.6% correct assistance to the police officers in the right direction (79.9% correct positive predictions and 17.7% correct negative predictions). As a consequence, the performed tests can be seen as a positive and needful tool for the police to get an immediate response to their initial suspicion and to take the right steps concerning a following legal action.  相似文献

This analysis of the change in subjective well-being attempts two aims. On the one hand, the change of subjective well-being over the time period from 1984 to 2002 will be considered. Effects of age, period and cohorts will be analyzed simultaneously. Education and educational expansion are considered as social mechanisms behind these processes of change and therefore introduced into the analyses. Methodologically, a multilevel approach is chosen. To analyze life satisfaction independently from health aspects, satisfaction with health will be controlled for. Hierarchical Linear Models (HLM) will be used for data analysis. Data structure, applicability and parameter estimations of HLM will be considered in detail. The data base is the German Socio-economic Panel data set, although only the West German subsample is used for analysis. Results indicate – beside a strong influence of health satisfaction – robust effects of education, a substantial age effect and a weak negative cohort effect on life satisfaction.  相似文献

Inspired by the need to find lasting solutions to violent conflict, the author stated the research question by asking ‘how can community knowledge be given a new centrality so that it can contribute to innovative conflict resolution?’ In answering this question, the author argues that conflict mapping is a strong influential instrument not only for community research, but also to empower a community to deal with conflict, promote equity of discourse on all dimensions of a conflict, as well as to create a web of equal relationships among peace-builders to resolve conflicts. The conceptual framework addresses conflict mapping; the top-down/bottom-up approach to conflict resolution and introduces the concept ‘innovative conflict resolution’. Examples of centralising community knowledge in some African societies are offered. The conceptual framework and examples from Africa are then applied to practical conflict mapping that was performed as part of a community engaged participatory research project with a San community in South Africa.  相似文献

Machiavelli's 500‐year‐old treatise The Prince outlined the central features of the realist tradition in international relations. His premises led him to question the likelihood of efficacious and stable international law and international courts, a skepticism that has present‐day proponents. Machiavelli's reluctance was due to a combination of features of human nature and a focus on anarchic features of the relations among states. This article challenges these assumptions and implications: Other interpretations of human nature are closer to Machiavelli's text, and current relations among states are significantly different. The revised assumptions should make Machiavelli's followers more optimistic about international law and international courts.  相似文献

Naturally preserved and embalmed bodies from archeological contexts represent a powerful source of information for forensic investigators. They allow one to ascertain pathology, cause of death, to enhance diagnostic methodology, and to improve the analysis of altered remains. We investigated the complete head and lung remnants of a 3,500‐year‐old Egyptian dignitary by radiological, microscopic, and genetic approaches. The individual, a middle‐aged male, suffered from severe periodontitis, mild atherosclerosis, and experienced cardiogenic pulmonary insufficiency with recurrent mini‐bleeds and pulmonary edema. Histology and ancient DNA analyses excluded the presence of Mycobacterium tuberculosis or of any other pathogenic species. Based on our collection of evidence, we propose that acute decompensation complicating chronic cardiac insufficiency was the likely cause of death. The underlying causes for this failure remain unknown although chronic hypertension appears to be the most likely candidate. Our finding represents the earliest reported case of chronic heart failure in ancient mummies.  相似文献
