Archaeological remains can provide concrete cases, making it possible to develop, refine or validate medico-legal techniques.In the case of the so-called ‘Joan of Arc's relics’ (a group of bone and archaeological remains known as the ‘Bottle of Chinon’), 14 specialists analysed the samples such as a cadaver X of carbonised aspect: forensic anthropologist, medical examiners, pathologists, geneticists, radiologist, biochemists, palynologists, zoologist and archaeologist. Materials, methods and results of this study are presented here.This study aims to offer an exploitable methodology for the modern medico-legal cases of small quantities of human bones of carbonised aspect.  相似文献

This study examined whether female-to-male (FTM) psychological aggression predicted men’s relapse of substance use disorder (SUD) 6 months following substance use treatment. Men diagnosed with either a substance abuse or dependence disorder who had recently begun an SUD treatment program participated in the study with their female relationship partners (N = 173). Logistic regression was used to examine the relationship between baseline FTM psychological aggression and SUD relapse when controlling for baseline demographic, dyadic, substance abuse- and treatment-related variables, as well as frequencies of other male- and female-perpetrated aggressive dyadic behaviors. Higher frequencies of severe, but not minor, forms of FTM psychological aggression uniquely predicted an increased risk of relapse at 6 months follow-up. These data add to the developing research program highlighting the negative sequelae of female-perpetrated psychological aggression and also provide an empirical basis for targeting specific dyadic behaviors in the context of SUD treatment and relapse prevention.  相似文献

Several factors influence the reliability of eyewitness identification evidence. Typically, recognition for same-race faces is better than for different-race faces (the own-race bias), and alcohol intoxication decreases overall face recognition accuracy. This research investigated how alcohol intoxication influences the own-race bias. Asian and European participants completed tests of recognition memory for Asian and European faces when either mildly intoxicated (mean breath alcohol concentration of .05) or when sober. Compared to their sober counterparts, intoxicated participants showed a reduced own-race bias. Specifically, alcohol intoxication had a larger negative effect on the recognition of same-race faces compared to different-race faces. The legal and theoretical implications of these results are discussed.  相似文献

This article makes recommendations as to “Best Practices” for the training of mediators in court‐connected settings. The authors’ findings cover issues including the design of training programs, the importance of experiential learning through role‐plays, teaching methods for adult learners, class size and length, training ethical mediators, suggested trainer qualifications, and recommended regulatory practices for administrators. Data comes primarily from an assessment of mediation training and regulation in Florida, but the findings hold insights for court‐connected mediation programs throughout the United States. Additionally, the authors highlight the benefits of a collaborative assessment approach involving all stakeholder groups and facilitating smooth implementation of any needed changes.  相似文献

The advance of reproductive technology, coupled with a legal system that cannot keep up, has had a detrimental effect on posthumously conceived children. There is controversy over whether a child conceived after the death of one parent, by way of reproductive technology, is considered a child of that parent for inheritance purposes. An overwhelming majority of state legislatures have not given consideration to the unique question that posthumously conceived children pose. Legislative inaction has forced state courts to apply antiquated laws in the midst of a technological revolution. The result: children are being denied inheritance rights to their deceased parent's estate solely because of the way they were conceived. This Note advocates that all children should be given the same rights and benefits regardless of how they are conceived. To accomplish that goal, this Note proposes a model state statute to be adopted in all states. The model statute deems a posthumously conceived child to be the child of his or her deceased parent, and thus entitled to inheritance rights, if 1) the posthumously conceived child was provided for by will, or 2) the deceased parent intended to be a parent; there is a genetic relationship between parent and child; the child is born within three years from the death of his or her deceased parent; and the child's best interest, balanced against the state's interests, exceeds the state's interest. The desired effect of the statute is to put posthumously conceived children on equal footing with naturally conceived children.  相似文献

In this study, we randomly assigned 123 sixth and seventh grade classrooms from seven middle schools in the greater Cleveland area to one of two five-session curricula addressing gender violence/sexual harassment (GV/SH) or to a no-treatment control group. A baseline survey and two follow-up surveys were administered immediately after the treatment (Wave 2) and about six months post-treatment (Wave 3). In an earlier paper, we demonstrated the effectiveness of two approaches to youth GV/SH prevention programming (a fact-based, law and justice curriculum and an interaction-based curriculum). In this paper, we explored whether these largely positive findings remain for both girls and boys, including whether girls experience higher levels of GV/SH than boys. Most of our statistical models proved to be non-statistically significant. However, in 2 of our 48 victimization/perpetration (any violence, sexual violence and non-sexual violence) models (across two post-intervention follow-up points), we observed that the interventions reduced peer (male or female, non-dating partner) sexual violence victimization and reduced peer perpetration, but another outcome model indicated that the interventions increased dating perpetration. These mixed findings will need to be explored further in future research. Regarding our primary research question, we observed no statistically significant differences for the treatment multiplied by gender interaction terms for any of the perpetration or victimization outcome models, suggesting that the treatment had similar effects on girls and boys. However, we did observe that boys are more involved in violence than girls: both as victims and perpetrators. Boys experienced significantly more of three types of victimization from peers and dating partners compared to what girls experienced at the hands of their peers and dating partners. As perpetrators, boys committed more sexual victimization against peers (immediately post-intervention only) and more sexual victimization against dating partners than girls. The implications of these results are discussed.  相似文献

According to World Bank policy, countries remain eligible to borrow from the IBRD until they are able to sustain long-term development without further recourse to Bank financing. Graduation from IBRD is not an automatic consequence of reaching a particular income level, but rather is supposed to be based on a determination of whether the country has reached a level of institutional development and capital-market access that enables it to sustain its own development process without recourse to Bank funding. This paper takes a positive approach to IBRD graduation policy, investigating what income and non-income factors appear to have influenced graduation status in recent decades, based on panel data for 1982 through 2009. Explanatory variables include the per-capita income of the country, as well as measures of institutional development and market access that are cited as criteria by the graduation policy, and other plausible explanatory variables that capture the levels of economic development and vulnerability of the country. We find that the observed correlates of Bank graduation status are generally consistent with the stated policy. Countries that are wealthier, more creditworthy, more institutionally developed, and are less vulnerable to trade, financial, and other shocks are more likely to be graduates. Predicted probabilities generated by the model conform closely to the actual graduation and de-graduation experiences of Trinidad and Tobago and Korea, among other countries, and suggest that Hungary and Latvia may have graduated prematurely—a prediction subsequently borne out by the large loans that they later received from the IBRD in the wake of the global financial crisis.  相似文献
