There are a number of forensic cases in which the identification of the epithelial cell type from which DNA originated would provide important probative evidence. This study aimed to develop a technique using histological staining of fixed cells to distinguish between skin, buccal and vaginal epithelium. First, 11 different stains were screened on formalin-fixed, wax-embedded cells from five women. Samples were analysed qualitatively by examining staining patterns (colour) and morphology (absence or presence of nuclei). Three of the staining methods – Dane's, Csaba's and Ayoub-Shklar – were successful in distinguishing skin epithelial cells from buccal and vaginal. Second, cells were smeared directly onto slides, fixed with one of five fixatives and stained with one of the three stains mentioned above. Methanol fixation, coupled with the Dane's staining method, specific to keratin, was the only technique that distinguished between all three cell types. Skin cells stained magenta, red and orange and lacked nuclei; buccal cells stained predominantly orange–pink with red nuclei; while vaginal cells stained bright orange with orange nuclei and a blue extracellular hue. This staining pattern in vaginal cells was consistent in samples collected from 50 women aged between 18 and 67. Identification of cell type from unlabelled micrographs by 10 trained observers showed a mean success rate of 95%. The results of this study demonstrate that histological staining may provide forensic scientists with a technique for distinguishing between skin, buccal and vaginal epithelial cells and thus would enable more conclusive analyses when investigating sexual assault cases.  相似文献

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR® SGM Plus® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h.  相似文献

On 13 December 2006, the General Assembly of the United Nationsadopted the Convention on the Rights of Persons with Disabilities(CRPD) and an associated Optional Protocol. The formulationof the CRPD has been hailed as a great landmark in the struggleto reframe the needs and concerns of persons with disabilityin terms of human rights. The CRPD is regarded as having finallyempowered the world's largest minority to claim their rights,and to participate in international and national affairs onan equal basis with others who have achieved specific treatyrecognition and protection. This essay interrogates the intellectualantecedents of the CRPD and its continuity and discontinuitywith 25 years of international law and its struggles with disabilityand human rights. It then explores the text of the CRPD, criticallyexamining its potential contribution to the realisation of therights of persons with disability.  相似文献

Performance management has been a focus of scholars and practitioners for more than 25 years, yet the use of performance information has not greatly expanded as a result of this attention. Acknowledging that performance measurement is not an end in itself but rather a means to enhance focus on results and value, this article evaluates the determinants of the use of performance information by local government administrators. An online survey was administered to local government employees involved in the 2015–16 Florida Benchmarking Consortium. Analysis of the data demonstrates that institutionalization of performance measurement has the strongest statistically significant positive association with the use of performance information, followed by the design adequacy of the performance measurement system.  相似文献

Early trauma, especially alleged recollected sexual or ritualistic abuse, has dominated both the clinical and legal systems recently. The clinical/legal challenge is to discern between true abuse and false memories. Modern medical technology has provided new insights into the operation of the brain along with the central and peripheral nervous systems and their relationship to the endocrine system. We now have a better understanding of how our system processes trauma and severe anxiety. An understanding of trauma recollection and client's susceptibility to causal suggestions from the neuropsychological perspective is crucial when these types of abuses are alleged.  相似文献

Governments can intervene to a greater or lesser extent in managing the risks that citizens face. They can adopt a maximal intervention approach (e.g., COVID-19) or a hands-off approach (e.g., unemployment), effectively “responsibilizing” their citizens. To manage the cyber risk, governments publish cyber-related policies. This article examines the intervention stances the governments adopt in supporting individual citizens managing their personal cyber risk. The authors pinpoint the cyber-related responsibilities that several governments espouse, applying a “responsibilization” analysis. Those applying to citizens are identified, thereby revealing the governments' cyber-related intervention stances. The analysis reveals that most governments adopt a minimal cyber-related intervention stance in supporting their citizens. Given the increasing number of successful cyber attacks on individuals, it seems time for the consequences of this stance to be acknowledged and reconsidered. The authors argue that governments should support individual citizens more effectively in dealing with cyber threats.  相似文献
