Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method.  相似文献

Abstract: The administrative discretion of civil servants is a central topic in public administration literature. Some authors view it as necessary and beneficial, while other researchers see it is a source of widespread abuse. However, reforms inspired by the “new public management” taking place in a number of public administrations are promoting greater managerial flexibility. In parallel with these modernization initiatives directed at administration, scandals continue to shake politico‐administrative life, and ethical issues are increasingly at the heart of public action. It is within this context that we question the relationship between an increasing managerial discretion and the development of an ethics infrastructure. Which areas are at risk? Can ethics help overcome the potential abuses of power? How do managers perceive their ability to be flexible and the role of ethics in their work? How do you implement the ethical requirements developed in various standards documents? These are the principal themes addressed in this article that presents the findings of a qualitative case study conducted in a Quebec ministry in 2008–2009. Our results show that, contrary to what promoters of the new public management claim, managers have little, if any, discretionary power in matters of financial management. Their actions and decisions are strictly governed by hierarchical control mechanisms or a computer system. This explains in part why taking ownership of general principles and establishing an ethics infrastructure remain a formal process.  相似文献

Abstract

THIS STUDY was set up to investigate the possibility of a relationship between the General Certificate of Education ('G.C.E.’) ‘A’ level qualifications of the entrants on to the law degree courses at Trent Polytechnic and their degree classifications.

Very little evidence was found of any such significant relationships. Further analysis of both G.C.E. ‘A’ and ‘O’ level qualifications similarly showed no significant relationships except in the case of ‘O’ levels. The most clear finding was that significant relationships do exist between being a full‐time female student and obtaining a good honours classification, and that all LL.B. Legal Studies (four‐year sandwich) students have a better chance of obtaining good honours than do LL.B. Law (three‐year full‐time) students.

Various other analyses were also attempted, but no other significant relationships were found, although it is possible that choice of final‐year options may influence degree classifications.

Overall, this study suggests that while G.C.E. results may be suggestive of a basic ability to complete degree courses successfully, they do not predict degree classifications. From this I draw the conclusion that G.C.E. results should not be used to exclude students from these, and possibly other, courses in higher education.

In considering the possible predictive value of the ‘A’ level G.C.E. qualifications of entrants on to the law degree courses at Trent Polytechnic and their degree classifications, other possible predictive relationships and factors were also investigated, in order to examine whether any other (reasonably available) variables were linked to degree classifications. Analyses were therefore carried out in relation to ‘O’ level G.C.E., gender, age of student, course, G.C.E. subject‐groupings and course progress. Other variables were not possible to test because of the quality of the information available.  相似文献
