In this proof-of-concept study, high-resolution melt curve (HRMC) analysis was investigated as a postquantification screening tool to discriminate human CSF1PO and THO1 genotypes amplified with mini-STR primers in the presence of SYBR Green or LCGreen Plus dyes. A total of 12 CSF1PO and 11 HUMTHO1 genotypes were analyzed on the LightScanner HR96 and LS-32 systems and were correctly differentiated based upon their respective melt profiles. Short STR amplicon melt curves were affected by repeat number, and single-source and mixed DNA samples were additionally differentiated by the formation of heteroduplexes. Melting curves were shown to be unique and reproducible from DNA quantities ranging from 20 to 0.4 ng and distinguished identical from nonidentical genotypes from DNA derived from different biological fluids and compromised samples. Thus, a method is described which can assess both the quantity and the possible probative value of samples without full genotyping. 相似文献

Pi Alpha Alpha (PAA) is the national academic honor society for public administration. This study presents the results of a comprehensive survey of PAA Chapter advisors focusing on inductee characteristics, induction requirements, chapter activities, chapter officers, and suggestions for improving PAA chapter effectiveness. NASPAA sponsored the survey and provided relevant logistical support. The results indicate that PAA is meeting its major objectives, but several areas require attention including enhancing the activity mix, improving recruitment practices for chapter officers, and a dedicated means for disseminating information on chapter activities through a newsletter and a chapter directory. 相似文献

This article addresses three questions concerning the legal regulation of the use of race as a category in biomedical research: how does the law currently encourage the use of race in biomedical research?; how might the existing legal framework constrain its use?; and what should be the law's approach to race-based biomedical research? It proposes a social justice approach that aims to promote racial equality by discouraging the use of "race" as a biological category while encouraging its use as a socio-political category to understand and investigate ways to eliminate disparities in health status, access to health care, and medical treatment. 相似文献

Within the past decade, restorative justice has emerged as a truly global phenomenon. Although retributive justice has dominated the penal landscape, more recently, restorative principles at sentencing have attracted increased attention. Restorative sentencing emphasizes the importance of compensation and reconciliation between victims and offenders and pays less attention to establishing proportionality between the seriousness of the offense and the severity of the sentence imposed. Although voluminous (and proliferating), the scholarly literature on restorative justice has to date neglected one critical issue: public opinion with respect to this justice paradigm. Public opinion researchers too, have generally overlooked this topic. The goal of this paper is to determine which elements of the new paradigm generate public approval, and which features are likely to encounter or provoke public opposition, drawing upon related international research published in English over the past 20 years (1982–2002). The review reveals widespread support for restorative sentencing options, such as community service, compensation, and restitution, particularly when applied to young offenders. However, it also seems clear that public support for these alternatives to punitive sentencing options declines as the seriousness of the offence increases, suggesting strong public adherence to the retributive principle of proportionality in sentencing. 相似文献
