Electrokinetic injection (EI) is the primary method used in forensic laboratories to load amplified PCR product in capillary electrophoresis for short tandem repeat (STR) fragment separation. Because all samples subjected to capillary electrophoresis use internal lane standard (ILS), this study investigated the consequence of varying the volume of ILS and its effects on allele peak heights and number of alleles detected. Results demonstrated that when the volume of ILS is reduced, the average peak height and number of alleles increased, thereby increasing the sensitivity of the detection method. Sizing anomalies were observed; however, they did not adversely affect accuracy and precision. The method developed in this study offers a simple and universal procedure to increase the alleles detected in forensic STR analysis. Reducing the volume of ILS to achieve greater sensitivity is applicable to all STR amplification kits and capillary electrophoresis instruments currently used in forensic DNA analysis. 相似文献

The number of women in the legal profession has grown tremendously over the last 40 years, with women now representing about half of all law school graduates. Despite the decades‐long pipeline of women into the profession, women's representation among law firm partnerships remains dismally low. One key reason identified for women's minority presence among law firm partners is the high level of attrition of women associates from law firms. This high rate of female attrition undermines efforts to achieve gender equality in the legal profession. Using a survey of 1,270 law graduates, we employ piecewise constant exponential hazard regression models to explore gendered career paths from private law practice. Our analysis reveals that, for both men and women, the time leading up to partnership decisions sees many lawyers exit private practice, but women continue to leave private practice long after partnership decisions are made. Gender differences in leaving private practice also surface with reference to cohorts, areas of law, billable hours, firm sizes, and career gaps. Notably, working in criminal law augmented women's risk of leaving private practice, but not for men, while taking time away from practice for reasons other than parental leaves, hastens both men's and women's exits from private practice. 相似文献

The Coalition government announced, in 2010, that between 2013 and the end of 2017 all existing claims to income-based welfare allowances, including housing benefit, would gradually move to the Universal Credit (DWP 2010). This article evaluates the performance of the Council Tax and Housing Benefits Administration Services under the current system for the delivery of these benefits since they were transferred fully to local authorities in 1993 up until December 2011. During this period the performance of local government has been influenced by four successive national delivery regimes, namely: Compulsory Competitive Tendering (CCT); Best Value; Comprehensive Performance Assessment (CPA) and Comprehensive Area Assessment (CAA). An earlier article (Murphy, P., Greenhalgh, K. and Jones, M., 2011. Comprehensive performance assessment and public services improvement in England – a case study of the benefits administration service in local government. Local Government Studies, 37 (6), pp. 579–599) examined the CPA period in detail and found a significant improvement in performance across all types of authorities in all parts of the country during this period. The current article complements this earlier analysis and provides a longer-term perspective on the performance of the benefits service between 1993 and December 2011. The findings of this article show that under CCT the performance of the system was poor, there were wide variations in individual local authority performance, with many acknowledged inadequacies in the system and unacceptably high levels of fraud. However, towards the end of CCT and in the subsequent Best Value period the antecedents of some of the tools and techniques subsequently used to drive improvement in the CPA era were either put in place or were being developed. The Best Value period itself did not show significant improvements in performance and it was not until many of the initiatives were refined, developed and applied within the CPA framework that sustained and significant improvements became evident. This overall improvement generally continued under the CAA although the previous trend of consistent reductions in the variation between authorities’ performance had changed between 2009–2010 and 2011–2012. It is too early to judge whether these latest trends will be maintained under the Coalition government’s localism regime. 相似文献
