Genotype and allele frequencies for STR loci D3S1358, vWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820 were investigated in 289 unrelated Italian Caucasian individuals from the North and South regions. After co-amplification by polymerase chain reaction, automatic DNA profiling of these nine STR loci was performed by ABI PRISM((R)) 310 DNA Genetic Analyzer. For each locus, statistical parameters for forensic and paternity purposes were then calculated; the combined power of discrimination and the combined power of exclusion of all nine loci were 0.9999999999917 and 0.99992 for the Northern population and 0.9999999999921 and 0.99991 for the Southern population.  相似文献

How do we think about mass murder? While the principle of responsibilityprovides an effective mechanism for the repression of mass murder(notably through Article 25 ICCSt.), analysis of the ‘actingout’ of mass murder by perpetrators requires a criminologicalperspective. Analysis of criminogenic processes, and of genocidallogic, helps us go some way in understanding how perpetrators‘act out’ mass murder. Such an approach also leadsus to identify a long silence in the social sciences: mass murderhas become a legitimate field of social scientific study onlyrecently; it also has the advantage of exposing the shortcomingsof many concepts. This article deals with works focusing on‘mass murder’ and suggests new research paths inthe social sciences.  相似文献

To date, there is a lack of family interventions for family members of persons with a mental illness who offended (PMIO). With the aim of addressing this issue, a Family Support Group (FSG) has been developed. The current pilot study investigated the impact of two pilot FSGs for family members of PMIO in relation to quality of life, burden, coping strategies, and resilience. Family members completed several questionnaires (i.e. WHOQOL-BREF, ZBI-22, CERQ, RS-nl) both before and after the group intervention. A total of 20 family members participated in both FSGs. The results indicated that participants experienced less self-blame, a decrease in loss of control over their lives, and improved emotional well-being. The findings showed that attending an FSG can be empowering for family members as it offers support in the management of emotional experiences and coping strategies.  相似文献

The aim of this presentation was to share an uncommon form of sudden death, suffered by a 64‐year‐old woman, due to a mechanical obstruction of hypopharynx by an undiagnosed B‐cell lymphoma, infiltrating the inferior pharyngeal constrictor muscle. A forensic approach by means of scene investigation, circumstantial data collection, autopsy, and histological and toxicological investigations led to conclude that the cause of death was asphyxia, correlated with B‐cell lymphoma of the hypopharynx. The autopsy examination highlighted the presence of a wall thickening, infiltrating, and projecting into the hypopharynx lumen. The histological analysis showed the essential finding of a B‐cell lymphoma of the hypopharynx, diffusely infiltrating the inferior pharyngeal constrictor muscle. To conclude, this case demonstrates once more that in the absence of specific data, a thorough forensic investigation including autopsy, histological examination, and circumstantial data collection is mandatory to reach a correct cause of death.  相似文献

Many Western-style democracies have witnessed a general shift in the distribution of crime prevention responsibility, away from the state and increasingly to citizens themselves. Civil society is today more and more often called upon as an additional policing resource. This article explores the phenomenon of voluntary citizen participation in policing in Sweden, based on an analysis of 9280 news-media articles. One state-sanctioned (the Volunteers of the Police) and one autonomous civic (Missing People Sweden) initiative were examined, from their respective start until 2017, to understand the role played by police–citizen partnerships in the establishment and legitimation of voluntary policing forms in Sweden. A high degree of integration between police and volunteer work was found, enabling not only effective citizen participation, but also having an influence on police operations. The more effective and publicly visible the voluntary policing bodies were, the more pressure there was on the police to defend its legitimacy, ally itself with the volunteers and regulate the latter’s activities while holding them responsible for their actions. Arguably, however, with the police–citizen relationship being one of integration and mutual dependence, the division of labour and the accountability of both parties risk becoming blurred or even confused.  相似文献

This paper suggests that smallholder farmers in sub-Saharan Africa (SSA) are well placed to seize the opportunities from expanding global and regional demand for agricultural products but that this will require a shift from extensive to more intensive production systems. The ability of SSA's smallholder farmers to increase on-farm investments in productivity is, however, constrained by their capacity to manage the risk-return trade-offs in moving towards intensified agriculture. While stakeholders are increasing their investments to assist smallholders in SSA to participate in integrated supply chains, the returns in terms of technical and financial results from these investments are generally lower than in other developing regions. This paper suggests that this is, at least in part, a consequence of problems associated with the role of spatial and temporal coordination in program delivery. Hence, much more focus needs to be devoted to delivering goods and services for smallholders at the right place and the right time, and this should be better monitored and evaluated in the context of development programs.  相似文献

Abstract

Few previous studies have explored the characteristics and dynamics of adolescent sibling incest. The objectives of this paper were twofold: first, to conduct a literature review that accounts for earlier research in the area, and secondly, to conduct a clinical study to explore differences regarding the characteristics of a group of adolescent sibling incest offenders (n=21) compared to a group of adolescent non-sibling offenders (n=24). Comparisons were made regarding variables such as family dysfunction, the offenders' prior victimization and offending behaviour. The data were derived from intake assessment files and semi-structured interviews with 45 adolescents who had sexually offended. The sibling incest offender group had grown up more often in dysfunctional families. Moreover, the results indicated that the offending behaviour in the sibling incest group was more severe. The study gives some empirical support for the possibility that sibling incest can be one sign, among others, of maltreatment during childhood.  相似文献

Why do certain ministers remain in their post for years while others have their time in office cut short? Drawing on the broader literature on portfolio allocation, this article argues that the saliency of individual portfolios shapes ministerial turnover. The main argument is that ministerial dismissals are less likely to occur the higher the saliency attributed to the ministerial portfolio since ministers appointed to important posts are more likely to have been through extensive screening before appointment. Importantly, it is also posited in the article that the effect of portfolio salience is conditioned by government approval ratings: when government ratings are on the decline, prime ministers are less likely to reshuffle or fire important ministers than when approval ratings are improving. To test these claims, Cox proportional hazards models are applied to a new dataset on ministerial turnover in Scandinavia during the postwar period. The results strongly support the proposition that portfolio saliency matters for ministerial survival, and that this effect is moderated by government popularity.  相似文献
