Mock jurors viewed a videotape of a simulated child sexual abuse trial and then deliberated to a unanimous verdict. The complainant was described as either a 13- or 17-year-old female child. Jurors voted to convict more often when the younger complainant was seen, and the younger complainant was rated as more credible than the older complainant. Female jurors voted the defendant guilty more often and rated the complainant as being more credible than male jurors. Jurors voted to convict more often and rated the defendant as less credible when expert psychological testimony was specific to the case than when they were presented with either general expert testimony or no expert testimony. Jurors who saw a psychological expert testify became less accepting of child sexual abuse misconceptions than those in the no expert control condition. The implications of these findings are discussed.Millbrook Correctional Centre 相似文献

The incidence of municipal default is closely related to the business cycles in this country. During national depressions nearly all sectors and regions experience defaults, although not with equal severity. Regional borrowing behavior during the boom years preceding depression determines which regions will be most severely affected by national depression. The history of state and local borrowing is briefly surveyed with attention to four major periods of economic expansion and the national depressions that followed. Regional development cycles are then reviewed with a focus on several cases: special district defaults both at the turn of the century and today; Detroit at the beginning of the automobile industry; and Florida in the 1920s. New York City and Cleveland are analyzed in the context of urban crises. Revenue bond defaults, including toll roads and the Washington Public Power and Supply System (WPPSS) are analyzed for special recurring patterns. 相似文献

The current backlog of casework is among the most significant challenges facing crime laboratories at this time. While the development of next-generation microchip-based technology for expedited forensic casework analysis offers one solution to this problem, this will require the adaptation of manual, large-volume, benchtop chemistry to small volume microfluidic devices. Analysis of evidentiary materials from rape kits where semen or sperm cells are commonly found represents a unique set of challenges for on-chip cell lysis and DNA extraction that must be addressed for successful application. The work presented here details the development of a microdevice capable of DNA extraction directly from sperm cells for application to the analysis of sexual assault evidence. A variety of chemical lysing agents are assessed for inclusion in the extraction protocol and a method for DNA purification from sperm cells is described. Suitability of the extracted DNA for short tandem repeat (STR) analysis is assessed and genetic profiles shown. Finally, on-chip cell lysis methods are evaluated, with results from fluorescence visualization of cell rupture and DNA extraction from an integrated cell lysis and purification with subsequent STR amplification presented. A method for on-chip cell lysis and DNA purification is described, with considerations toward inclusion in an integrated microdevice capable of both differential cell sorting and DNA extraction. The results of this work demonstrate the feasibility of incorporating microchip-based cell lysis and DNA extraction into forensic casework analysis. 相似文献

Drug screening through urinalysis is a widely accepted tool for rapid detection of potential drug use at a relatively low cost. It is, therefore, a potentially useful method for detecting and monitoring drug use in a variety of contexts such as the criminal justice system, pre-employment screening and a variety of treatment centers. This article explores the efficacy of two commercially available drug-screening assays: Online KIMS assay (Roche) and EMIT II assays. First, we evaluate the sensitivity and specificity of two immunoassays. A total of 738 urine samples were collected among adult arrestee populations from Chicago, New Orleans and Seattle through the Arrestee Drug Abuse Monitoring (ADAM) program. Partial samples were split within one laboratory and analyzed by both enzymes multiplied immunoassay technique (EMIT) II and kinetic interaction of microparticle in solution (KIMS) assays for a 10-drug panel (amphetamine, barbiturates, benzodiazepines, marijuana, cocaine, methadone, methaqualone, opiate, phencyclidine and propoxyphene). Gas chromatography-mass spectrometry (GC-MS) was used as a confirmation method for all positives from either EMIT II or KIMS for all experiments. Second, the paper examines whether using different testing laboratories plays a role in the final results. The same experiments were repeated at two different testing locations: one in California and one in London and England. Third, the paper studies whether drug testing results vary between two laboratories when each of them had used their own routine screening method: the Forensic Science Service (FSS) at Birmingham, United Kingdom with KIMS assay and Medscreen Limited at London, United Kingdom with EMIT II. In summary, both EMIT II and KIMS assays generate fairly consistent results. The concordance rate against each of the 10 drugs tested is relatively high (97.4-100%). The discrepancies, in most cases, occurred at drug concentrations near the cut-off levels. There were more discrepant results between two laboratories compared to when specimens were analyzed at the same laboratory using two different assays. 相似文献

Rural Latino immigrant women at risk of family violence may perceive churches as their only source of help. However, immigrant church leaders may be poorly equipped to address family violence in their congregations. This article describes a project designed to stimulate and support appropriate responses to family violence by rural immigrant churches, including those identified with conservative theological views on women. The primary goal was to provide rural Latino church leaders with culturally sensitive materials and resources they were willing to use with their congregations. We collaborated with local service providers who assisted in recruiting the church leaders for the pastors’ workshops where the resource materials were presented. Survey data indicated most of the pastors were receptive to the content and planned to incorporate it into their church work. Suggestions are made for future research on this culturally sensitive approach to addressing family violence in the immigrant community. 相似文献

Forensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri- and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty-seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three-point bending setup and recorded with a high-speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri- versus postmortem fractures. 相似文献

School can be regarded as an important factor in the development of children’s values and attitudes. Given this great importance of justice experiences for students’ development, this study aimed at examining the influence of perceived injustice in school on students’ emotions, well-being, and behavior with an experimental longitudinal design. In total, 196 students participated in this study and came to the university with their classes to receive extra teaching once a week for six consecutive weeks. To manipulate justice perceptions, a scenario of arbitrary privilege was chosen to lead students of the experimental group to experience injustice from a beneficiary perspective. We found that students in the experimental group reported higher well-being and a higher appreciation of the opportunity to learn than the control group did. Additionally, they showed an increase in justice-related negative emotions over time; that is, they expressed more of a bad conscience and stronger feelings of anger the more they became aware of their privilege. This study shows that even subtle experiences of injustice in school can have an impact on students’ outcomes. These results are discussed with regard to practical implications. 相似文献
