Two hundred prosecuting attorneys completed a survey concerning priorities in taking on animal cruelty cases and the factors that help or hinder prosecuting such cases. Respondents commented on the priority given such cases. Questions also addressed specific kinds of evidence that had been used to decide whether to take on a cruelty case and were used in court. Results showed that prosecutors most frequently relied upon “traditional” sources of evidence, including detailed medical and crime scene reports and good quality photographic evidence. Other sources of forensic evidence such as DNA, computer forensics, forensic accounting, blood, and trace evidence were rarely employed. Veterinary forensic evidence, including forensic necropsies and detailed medical reports, was viewed as an important factor by a majority of prosecutors in deciding whether to accept a case for prosecution and in achieving a successful outcome, but a need for additional training for investigators was indicated.  相似文献

Analysis of subdural hematomata has been used to suggest antemortem drug concentrations, with the assumption that materials within the hematoma are less subject to metabolism or degradation during any survival period and postmortem interval. We report the case of an 87‐year‐old woman whose death had not been reported to the coroner's office until postembalming. Autopsy revealed a traumatic brain injury with subdural hematoma causing a mass effect. Testing of the clot indicated a methanol concentration of 51.8 mg%. No additional analyses were detected. These findings suggest that methanol can be present in a postmortem hematoma sample, yet not represent a poisoning. Our findings also suggest that while the interior of hematomata do not necessarily represent completely “protected space” from postmortem diffusion of some blood constituents, such diffusion is not facile, and analysis may still provide useful indications of antemortem drugs present, if not actual concentrations.  相似文献

Community college (CC) students make up 45% of American undergraduates, but little is known about their experiences of intimate partner violence (IPV), or accompanying service use and needs. The current study used a sequential confirmatory mixed methods design among a simple random sample of female CC students (n?=?435), of whom 112 have experienced IPV in the past 12 months. Of these IPV survivors, 20 participated in qualitative follow-up interviews. The study assess use and perceived usefulness of college and community based resources, extent of social support, and perceived need for and barriers to service access. Campus based resources were rated as more useful than community based resources. Faculty were identified as important supports for survivors. Those experiencing IPV reported lower rates of social support compared to other students. A range of supports and services were endorsed as possibly useful by survivors. Survivors need services to address life generated risks that compound barriers to college completion created by abuse. CC survivors often balance work and parenting with education, and may benefit from different services than survivors in other educational settings.  相似文献

The legal landscape surrounding adoption by lesbian, gay, bisexual, transgender, or questioning/queer (LGBTQ) parents continues to be dynamic and variable across the United States, yet the topic is generally viewed favorably by Americans and increasing numbers of LGBTQ adults are becoming adoptive parents. In this essay, we explore intersections of sexual orientation, gender identity, and adoption law. We discuss connections between parenting (including adoption) and marriage rights, highlight the influence of varying legal contexts and discrimination for LGBTQ adults who pursue adoption (including case examples from Florida after the gay adoption ban was lifted), and incorporating the perspectives of adoption‐agency personnel working with LGBTQ clients.  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
