On June 1st, 2017, President Trump announced that the United States will be withdrawing from the Paris Climate Agreement, a move he has promised to make since his early campaign days. This move came as a shock to many people all over the world. The Paris Agreement is the world's first comprehensive climate agreement that aims to take proactive measures towards global warming. In order to fully understand this withdrawal, we must familiarize ourselves with its parent-treaty, the United Nations Framework Convention on Climate Change, and the constitutional precedent involved with such a change. 相似文献

This article assesses the utility of victim participation in the trials before the Extraordinary Chambers in the Courts of Cambodia, in fostering reconciliation and realizing restorative justice. Specifically, it investigates the parameters of a legal mechanism designed to give ‘victims of atrocity’ a voice, whilst striking a vital balance between rights of victims and rights of defendants to a fair trial. Where participation affords victims the opportunity to present their views and observations, thereby enhancing prospects for retributive and restorative justice, this article submits that participation affords the international community an historic opportunity to meet Rome Statute objectives to ‘not only to bring criminals to justice but also to help the victims themselves obtain justice’ (See Victims Witness Section at the ICC, < www.icc-cpi.int/Menus/ICC/Structure+of+the+Court/Victims>). Indeed while concrete benefits of participation remain to be seen, victim participation in the ECCC's case offers promise for breaking new ground, setting international standards and establishing precedence for other ad hoc and hybrid tribunals as well as the permanent International Criminal Court. 相似文献

Abstract: With <100 pg of template DNA, routine short tandem repeat (STR) analysis often fails, resulting in no or partial profiles and increased stochastic effects. To overcome this, some have investigated preamplification methods that include the addition of proofreading enzymes to the PCR cocktail. This project sought to determine whether adding proofreading polymerases directly in the STR amplification mixture would improve the reaction when little template DNA is available. Platinum Taq High Fidelity and GeneAmp High Fidelity were tested in Profiler Plus? STR reactions alone and in combination with AmpliTaq® Gold. All reactions included the additional step of a post‐PCR purification step. With both pristine low template DNA and casework samples, the addition of these polymerases resulted in comparable or no improvement in the STR amplification signal. Further, stochastic effects and artifacts were observed equally across all enzyme conditions. Based on these studies, the addition of these proofreading enzymes to a multiplex STR amplification is not recommended for low template DNA work. 相似文献

Purpose
Gottfredson and Hirschi, in A General Theory of Crime, argue that the primary source of self-control is parental socialization. Specifically, parents who fail to supervise their children, to recognize their child's deviant behavior, and to punish such behavior are more likely to raise children with lower levels of self-control. Recent empirical research, however, has broadened the explanatory factors to include sources within schools, neighborhoods, and individual factors as significant contributors to the development of self-control. This study proposes that maternal smoking during pregnancy places additional limits on the development of self-control.Methods
Using a subsample of the National Longitudinal Study of Youth (N = 542), we provide a comprehensive investigation of the variety of sources of self-control to include both individual and environmental covariates.Results
Results indicate that maternal smoking during pregnancy significantly impacts the development of self-control net of parental, neighborhood, and school socialization. We also found that individual sources of self-control significantly vary across race and neighborhood context.Conclusions
The sources of self-control are more complex than socialization from parents, schools, and within neighborhoods occurring in childhood and adolescence. 相似文献86.

This study aims to understand if greater severity of maternal posttraumatic stress symptoms (PTSS), related to maternal report of interpersonal violence, mediates the effects of such violence on (a) child PTSS as well as on (b) child externalizing and internalizing symptoms. Study participants were mothers (N = 77) and children 18 to 48 months recruited from community pediatric clinics. Data were analyzed continuously via bivariate correlations and then multiple linear regression. Post hoc Sobel tests were performed to confirm mediation. Paternal violence accounted for 15% of the variance of child PTSS on the PCIP-OR (β = .39, p ≤ .001). While the child's father being violent significantly predicts child PTSS related to domestic violence, as mentioned, when maternal PTSS is included in the multiple regression model, father's being violent becomes less significant, while maternal PTSS remains strongly predictive. Sobel tests confirmed that maternal PTSS severity mediated effects of paternal violence on clinician-assessed child PTSS as well as on maternal report of child externalizing and internalizing symptoms. When presented with a preschool-aged child who is brought to consultation for behavioral difficulties, dysregulated aggression, and/or unexplained fears, clinicians should evaluate maternal psychological functioning as well as assess and treat the effects of interpersonal violence, which otherwise may be avoided during the consultation. 相似文献

Autosomal STR typing alone seems to be no sufficient tool for resolving deficiency cases (e.g. cases of questioned paternity or half-sibships). Therefore, we investigated whether the additional analysis of RFLP single locus probes can improve the solution of such complicated kinship cases. We analyzed 207 children and men from 101 families using the AmpFlSTRIdentifiler multiplex PCR kit and three RFLP single locus probes. A comparison between each child and all unrelated men resulted in 11,023 man / child pairs. Less than three excluding STRs were found in 125 child / unrelated man pairs (1.13%). Additional analysis of RFLP results reduced the number of ambiguous cases to 35. Half-sibling pairs were simulated using STR results from 20 cases with high paternity probabilities (group 1) and relatively low paternity probabilities (group 2). Using a commercially available computer program we calculated probabilities for 778 half-sibling pairs. In 35 pairs (4.49%) half-sibling probabilities over 90.0% could be calculated. Additional investigation of RFLP single locus probes did not lead to a more reliable evaluation of these results. The combined investigation of autosomal STRs and RFLP single locus probes can satisfactorily solve deficient paternities but does not contribute to the solution of questioned half-sibships. 相似文献

Abstract: Several studies have investigated frontal sinus comparison for personal identification. One study addressed the statistical reliability of correct identification using automated digital methods and resulted in a 96% accuracy rate. Missed matches with the digital methods generally involved small, less featured sinuses. This study investigates the hypothesis that human examiners may be able to more accurately identify correct matches than digital methods, even when the comparisons involve small frontal sinuses. Participants were provided two sets of 28 radiographs and were instructed to identify matching radiographs and list the radiographs that did not have a corresponding match. Overall, error rates were low, with correct associations identified at a rate of 0.983. No incorrect associations (“false positives”) were made. Correct association rates were highest among participants “experienced” examining radiographs. Results support previous assertions that frontal sinus radiographs are a reliable means of personal identification even when the frontal sinuses are small. 相似文献

The purpose of this study is to compare a specialized community-oriented policing (COP) unit to a reactive unit on officer perceptions of public contact and officer perceptions of job performance. We also compare bicycle patrol officers to motor vehicle patrol officers within these units. Using a static group comparison design, questionnaires were distributed to officers within the Toronto Police Service (n = 178). Bicycle patrol is associated with more contacts with the public and higher rates of proactive policing when compared to motor vehicle patrol and bicycle officers are more likely to rate higher on several measures of crime control. Officers with a COP mandate engage with the public for a wider variety of reasons compared to those with a reactive mandate, and are more likely to rate higher on perceptions of performing job duties in a procedurally just manner. This study demonstrates the value of a specialized COP unit that includes bicycle patrol in achieving tenets of COP. It contributes to the literature on COP and the use of bicycle patrol in law enforcement by presenting the perspective of the police officer. 相似文献
