Drug levels in decomposed individuals are difficult to interpret. Concentrations of 16 drugs were monitored in tissues (blood, brain, liver, kidney, muscle, and soil) from decomposing pigs for 1 week. Pigs were divided into groups (n = 5) with each group receiving four drugs. Drug cocktails were prepared from pharmaceutical formulations. Intracardiac pentobarbital sacrifice was 4 h after dosing, with tissue collection at 4, 24, 48, 96, and 168 h postdosing. Samples were frozen until assay. Detection and quantitation of drugs were through solid phase extraction followed by gas chromatograph/mass spectrometer analysis. Brain and kidneys were not available after 48 h; liver and muscle persisted for 1 week. Concentration of drugs increased during decomposition. During 1 week of decomposition, muscle showed average levels increasing but concentrations in liver were increased many fold, compared to muscle. Attempting to interpret drug levels in decomposed bodies may lead to incorrect conclusions about cause and manner of death. 相似文献

The transfer between two-year and four-year colleges is a critical path to baccalaureate attainment. Yet students face a number of barriers in transfer pathways, including a lack of coherent coordination and articulation between their community colleges and four-year institutions, resulting in excess units and increased time to degree. In this paper we evaluate the impact of California's Student Transfer Achievement Reform Act, which aimed to create a more seamless pathway between the California Community Colleges and the California State University. We investigate whether the reform effort met its intended goal of improving baccalaureate receipt, and greater efficiency in earning these degrees, among community college transfer students. We tease out plausibly causal effects of the policy by leveraging the exogenous variation in the timing of the implementation of the reform in different campuses and fields of study. We find an overall positive effect on bachelor's degree attainment. This increase is driven entirely by increased transfer rather than an increased probability of earning a BA/BS conditional on transfer. We find only suggestive evidence that the policy led to greater efficiency (i.e., fewer units at graduation) in BA/BS receipt for transfer students. These findings are broadly consistent across student subgroups. 相似文献

The prevalence of autism spectrum disorder (ASD) in children and adolescents has increased over the past decade. Consequently, the courts and experts are more likely to be exposed to these children whose needs are highly heterogeneous. The present study aims to document judicial decision-making about children with autism spectrum as well as the parenting recommendations made by experts involved in these cases. There were 104 court decisions reviewed in Quebec over the past ten years. The results show that 85.6% of the decisions included a child custody assessment and that judges are more likely to order primary care to mother (56%). However, shared parenting (27%) and primary care to the father (17%) were also ordered in disputes involving an autistic child. Bivariate analyses revealed that challenges with parental monitoring and supervision were associated with court-ordered parenting arrangements. The present study revealed that a child custody assessment as well as father custody are more often observed than in the general population. This study highlights the need for further research to shed light on the best interests of children with ASD following the separation of their parents. 相似文献
