We have demonstrated that skin viability decreases at a measurable rate following death in an animal model. The decreased skin viability was measured by fluorescein diacetate and ethidium bromide using fluorescence emission spectroscopy. There is significant decrease of the fluorescence intensity of the fluorescein diacetate assay between the 1-4 h, the 6-24 h, and the >40 h time points postmortem. For times between 6-24 h and >40 h postmortem the ethidium bromide assay showed consistent and significant increases in signal. The fluorescence measurements in this study showed that under the experimental conditions the time of death could be determined for <4, 6-24, and >40 hapotmotrem. The application of these assays in the field will require further study of the environmental factors. 相似文献

Reviews the need for and development of expanded school mental health (ESMH) programs, which provide a continuum of mental health promotion and intervention through school–community partnerships. Since ESMH is a relatively new, but increasingly prominent field, countless issues are being addressed in practice and research and in efforts to bridge practice and research. We review particular content and context dimensions of ESMH in need of development including quality assessment and improvement, empirically supported practice, improving assessment and outcome evaluation, involving educators in the work, understanding school environments, and tailoring programs through qualitative research. Summaries of articles that amplify these themes are provided. 相似文献

This study reports findings from an evaluation of a new generation jail in a large southwestern state. The jail is one component
of a complex containing a traditional jail, an indirect supervision facility (barracks), and the new generation jail. Using
survey and operational data, we compare the new generation jail to the other two facilities. The findings provide generally
positive support for the effectiveness of the new generation jail. Inmates and staff were much more satisfied with the physical
facilities. Staff perceived it as more secure, though they reported only limited advantages in safety and security. Violence
and disciplinary problems were substantially lower. However, no savings in staffing levels were noted, nor were there differences
in job satisfaction for staff in the new generation jail. We discuss the implications of the findings and suggest additional
directions for jail evaluations. 相似文献

Abstract: The state of policy capacity within Canada's various levels of government has for some time been the subject of discussion both within the public services themselves and among the academic research community. Drawing on the results of a 2006 survey of deputy and assistant deputy ministers working in Canada's federal, ten provincial and three territorial governments, this article presents assessments made by the most senior leadership. The survey results show that ninety per cent of deputy ministers and assistant deputy ministers agree that policy capacity has changed but that the change is not uni‐directional. Both improvements and decline in policy capacity were observed, although assessments of decline were somewhat more pronounced. Moreover, improvements in policy capacity were found to be associated with a reduced focus on direct service delivery, a greater concern with long‐term planning, and the presence of a political leadership interested in innovation. Conversely, declining policy capacity was found to be linked to centralization of power, the loss of institutional memory, and “churning” within the ranks of the executive leadership. Additionally, level of government was also observed to be linked with change in policy capacity, with provincial deputies reflecting more negatively on policy capacity decline in their government than deputies at other levels. 相似文献

Previous studies have established that repeat victimizations occur more frequently than would be expected if households within a particular area were victimized randomly. This implies that characteristics of the household affect the victimization rate. Even controlling for these characteristics, we find that a Poisson model does not capture the distribution of victimizations because repeat victimizations are more concentrated than it would indicate. This leads us to adopt the negative binomial generalization of the Poisson model. Our analysis uses sociodemographic attributes of the household and community-level characteristics to predict victimizations, with the victimization data being the observed number of property crime victimizations from the 1992 British Crime Survey. The negative binomial generalization is found to be highly statistically significant and the crime concentration it implies becomes much more marked as the predicted number of victimizations increases. 相似文献

The present study involves the development of forensic DNA typing tests and databases for mule deer in the Province of Alberta. Two multiplex PCR reactions interrogating 10 loci were used to analyze samples from three populations of mule deer. Additionally, an amelogenin based sex-typing marker was used to determine the gender of samples. Results show that the tests and databases are appropriate for use in forensic applications. Additionally, the results indicate that there is little population structure in mule deer in Alberta and that no changes to management of this game species are suggested. 相似文献
