Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200. 相似文献

Have New Public Management (NPM) reforms in public organizations improved the quality, efficiency and effectiveness of the delivery of public policies? NPM reforms, understood as a style of organizing public services towards the efficiency and efficacy of outputs, have been controversial. They have been accused of importing practices and norms from the private sector that could collide with core public values, such as impartiality or equity. Yet, with few exceptions, we lack systematic empirical tests of the actual effects that NPM reforms have had on the delivery of public services. In this introductory article, we summarize a special issue devoted to cover this gap. And, overall, we find that neither the catastrophic nor the balsamic effects of NPM reforms are confirmed, but the success (or failure) depends on the administrative, political and policy context those reforms take place. 相似文献

Public administration reforms have propagated the use of private sector management skills in the public sector, and an increased openness to managers with a private sector background. This has created a debate between those who think private sector experience improves public institutions by bringing core managerial values such as results orientation, efficiency, or openness to innovation, and those who argue that private sector experience can damage core public sector values, such as impartiality and equity. Despite the abundant anecdotal evidence, broad empirical evidence on the effects of private sector experience on public managers' values remains limited. Using data from a survey among central government top managers in 18 European countries, we show that public managers with private sector experience have, as expected, more core managerial values. Yet, unlike the conventional view, core public values do not suffer. 相似文献

This study empirically explores the linkage between urbanization and deforestation while controlling for the role of energy consumption, trade openness, and economic growth within recent data from 1971 to 2015. To do this, we employed the vector error correction‐Granger causality approach and Pesaran's autoregressive distributed lag cointegration technique. The Bayer–Hanck cointegration test establishes an equilibrium relationship among the variables. Results reveal that economic growth, energy consumption, and urbanization have a significant impact on deforestation in Nigeria, thereby reducing the quality of the environment. Short‐ and long‐run unidirectional casualty flows from urbanization to deforestation. Therefore, policies for reducing deforestation and enhancing environmental sustainability for growth and development were suggested. 相似文献

The competence of the practicing bar has been subjected to substantial criticism in recent years. Since law schools have a virtual monopoly over access to the bar and licensure is granted without further training, legal education has been a particular focus of attack and reform efforts. Yet there has been little systematic study of what skills and knowledge are important in the actual practice of law or the relevant contributions of legal education. This study of practicing lawyers in Chicago examines the nature of the competencies important to the practice of law and the sources lawyers credit for contributing to their development.
Practitioners cite a broad range of skills, many of them not unique to the practice of law, with their importance varying by the predominant legal specialty practiced. The data further indicate that law schools play but a part in the development of skills and knowledge important to the practice of law and that experience, both prior and subsequent to graduation, plays a significant role. The evaluation of law schools' contributions is related to opportunities for further training, particularly in the context of law firm practice. There is, however, a strong general view that law schools rather uniformly concentrate on some skills to the exclusion of others and that the former are not necessarily those that lawyers think are most important to the practice of law. 相似文献

In an earlier paper we reported that teachers' ratings of child guidance clinic children were associated with the children's global adjustment in young adulthood. Teachers' ratings, especially the peer relations measure, far surpassed other data sources in predicting general adult mental status. Other sources were developmental history, social history, family information, and psychiatric and psychological evaluations. The purposes of the present investigation were to evaluate mother-son reliability on adulthood information, and to determine whether teacher-rated behaviors of clinic boys predicted specific adult behaviors or were only globally related. Interviewed separately when sons were young adults, mothers and sons closely agreed on sons' adult behavior, with mothers somewhat underreporting sons' negative behaviors. The major finding was that one teacher-rated item,fails to get along with other children, was closely associated with a wide spectrum of adult behaviors. This was not due to the peer relations indicator serving as a global statistic reflecting general childhood impairment. It was also found that composite scores of childhood and adulthood bad conduct were significantly related to each other.Data collection was funded by NIMH Grant #MH-23441-02A1, and by the William T.
