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

Lord Cottenham was a significant legal figure in nineteenth-century Britain. He was a Lord Chancellor and Keeper of the Great Seal in both Lord Melbourne's and Lord Russell's administrations. Yet compared with his peers he has faded into obscurity, because his contribution to the reform of the Court of Chancery and the development of the law, particularly equity, has not been fully appreciated. It will be argued that Lord Cottenham was not as successful as his successors in reforming Chancery because his attempts to do so were flawed by the view that incremental reform would redress the problems which beset the Court. However, he made some highly significant contributions to equitable doctrine, sometimes taking a practical approach to judicial decision-making and laying the foundation for some modern doctrines.  相似文献

A rapid and sensitive determination of cannabinoids in urine is important in many fields, from workplace drug testing over toxicology to the fight against doping. The detection of cannabis abuse is normally based on the quantification of the most important metabolite 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid (THCA) in urine. In most fields THCA needs to be present at a concentration of exceeding 15 ng/mL before a positive result can be reported.The method described in this paper, combines a 4 min GC–MS/MS method with a fast sample preparation procedure using microwave assisted derivatisation in order to complete the quantification of THCA in urine in 30 min, using only 1 mL of urine.The method is selective, linear over the range 5–100 ng/mL and shows excellent precision and trueness and hence, the estimated measurement uncertainty at the threshold level is small. The method also complies with applicable criteria for mass spectrometry and chromatography. Therefore the method can be used for rapid screening and confirmatory purposes.  相似文献

This study was conducted to determine the degree of discrimination obtained between non-denim blue cotton fibres using visible–UV range microspectrophotometry alone. To this end, samples of fibres were taken from 100, non-denim, blue cotton, outer garments, including t-shirts, trousers and jumpers and subjected to analysis by both visible and UV range microspectrophotometry. The results obtained from the samples of each garment were compared to determine if they ‘matched’ or not. From an initial visual comparison of the garments it was possible to subdivide the samples into two populations consisting of 73 ‘dark blue’ garments and 27 ‘mid-blue’ garments. It was found that of the 73 ‘dark blue’ garments, 22 distinct sub-populations could be distinguished using visible range MSP, this figure being increased to 43 when the analysis was extended into the UV range. In the case of the 27 ‘mid-blue’ garments, 9 distinct sub-populations were discriminated using visible range MSP, this figure being increased to 17 when the analysis was extended into the UV range. The discriminating power (i.e. the number of discriminated pairs divided by the number of possible pairs) of visible range microspectrophotometry was calculated as 0.89 for ‘mid-blue’ garments and 0.87 for ‘dark blue’ garments. Extending microspectrophotometry into the UV range increased discrimination by 7%, giving a discriminating power of 0.96 for both mid and dark blue cotton fibres which was similar to that reported by a previous study where this method was combined with light and fluorescence microscopy.Intra-garment variation was found to be negligible. The implications of this study for casework are discussed and a revised analytical pathway for the comparison of this fibre type/colour combination using microspectrophotometry as a primary screening tool, is proposed.  相似文献

Introduction: ‘Head banging’ is a common form of self-harm, linked to numerous negative outcomes including significant brain damage. However, little research has investigated head banging behaviour and its correlates in clinical populations. Method: Head banging episodes were identified from the incident records (n = 5417) of two inpatient forensic services (one intellectual disability and one mental health), using relevant search terms. Rates were compared between individual patients, by gender, diagnosis and level of security. Incident accounts were analysed qualitatively using thematic analysis. Results: Head banging incidents occurred approximately every 3 days in each service, with 229 incidents recorded in 1 year. Individual patient rates varied widely, ranging from 1 to 38 incidents within 1 year. Women, and patients in higher levels of therapeutic security, were significantly more likely to engage in head banging. Qualitative incident reports indicated that head banging was associated with mental distress, anger and psychotic experiences. Discussion: Head banging occurs frequently in forensic services, and has documented associations with traumatic brain injury in affected individuals, thus negatively impacting progress through the care pathway and treatment outcomes. Further research should investigate short- and long-term management strategies and treatment approaches, in order to minimise harm.  相似文献

Policy network analysis has been criticized for failing to adopt a sufficiently dynamic approach to the study of policy-making processes. There have been, however, a number of studies illustrating how policy networks change, recognizing that they are not static entities but respond to changes in the policy environment. This article applies policy network analysis to the negotiation of plans to implement the 1994 EC Packaging and Packaging Waste Directive in the UK and provides a further contribution to the literature on the formation and transformation of policy networks. The analysis reveals significant changes in the structure and operation of the policy network during the period studied. The reasons for such changes confirm those put forward by other policy network analysts, such as the power of the actors involved and conflicts between them. Other reasons include the role of the government and the tight schedule laid out by the directive.  相似文献
