The Ge.F.I. (the Italian Speaking Working Group of ISFG) has launched the first DNA Proficiency Test in 2012. The aim is to increase the external quality controls in forensic genetics in Italy and to drive to the standardizations of methods within the laboratories. Reference and mixed stains typing as well as statistical exercises were proposed and 26 laboratories submitted results.  相似文献

Participation in interlaboratory quality control exercises is one of the main mechanisms currently used for quality assurance and continuous improvement of the trials. The objective of this study was to design, to manage and to evaluate the Colombian Exercise Interlaboratory Quality Control 2012 (CEIQC-2012). The CEIQC-2012 included both practical and theoretical exercises. For practical exercise three samples were provided, two from blood and one from buccal swab, all on FTA cards, participants were requested to process the samples according to the methods and the markers used routinely in their own laboratories. For theoretical section four exercises were sent, and only one was mandatory, the remain have different degrees of difficulty and were optional. In the mandatory exercise, the participants were asked to calculate the partial and total IP of 15 autosomal STRs markers of an alleged father and a son. This exercise involved 28 laboratories from 6 Latin American and Caribbean countries (Brazil, Ecuador, Peru, Panama, Dominican Republic and Colombia), all reported results for the theoretical mandatory and 27 for the practical. Fifty-four STR markers distributed in autosomal, Y and X chromosomes were under consensus. The Proficiency Test conducted through the Colombian National Reference Laboratory has become a useful tool for quality assurance of all Colombian laboratories and some of Latin America and Caribbean that perform DNA testing to establish biological relationships. This exercise is also an excellent opportunity for constant experts training in the region.  相似文献

A new measure of opinion quality that we name "argument repertoire" (AR) is introduced and evaluated. AR refers to the relevant reasons that one has for one's own opinions and the relevant reasons that others with opposite opinions might have. The measure is shown to be reliable and to have construct validity. Those with elevated AR also were more likely to attend on-line deliberative groups during the presidential election and to contribute to those conversations. Those who participated in online deliberations tended to have higher AR scores on particular issues that were discussed. The role of AR in deliberative political groups is explored.  相似文献

Structural equation modelling was utilised to develop and test three models while exploring the causality effect of constructs. The models hypothesised that trust in the government was a result of interactions of several other forces: namely, citizens’ expectation, perception of service quality and satisfaction with these services. The article validates and replicates the findings on the question of causality between performance and trust. The findings were very consistent with the previous ones. The model incorporating citizen's demographic data provided the best fit. According to this model, citizen demographics, expectations and quality of services influence citizen satisfaction; and ultimately, citizen satisfaction influences trust in government. The perceived quality of all services provides significant standardised estimates. However, congestion in streets, parking facilities, parks and recreation and schools are the most salient drivers of citizen satisfaction. The variables of income, education level, years living in Abu Dhabi and marital status exert the highest influence on this satisfaction construct. Perception of quality of services has a significant effect on overall satisfaction; and overall satisfaction drives trust in local government officials. In addition, citizen expectation influences perceptions of the quality of service and overall satisfaction.  相似文献

Abstract

Since the enactment of New Labour's sustainable development agenda in 1999, English local authorities have been placed at the helm of a variety of devolved localism initiatives designed to foster sustainable communities that contribute to a high quality of life for existing and future generations. This paper considers the scale of the challenge that confronts local authorities in terms of attaining these outcomes, by drawing attention to their current quality of life situation. The baseline conditions in question are measured by reference to the Audit Commission's local quality of life indicators dataset, which it compiled in 2005 from a range of existing local government performance indicators. The dataset is subjected to k-means clustering and principal components analysis to assess how far English local authorities measure up to Labour's sustainable communities ideal and to highlight the type and degree of quality of life disparity that exists between them. The results from the analysis are used to evaluate the feasibility of Labour's devolved localism approach to sustainable community formation and to provide important insights to local policy makers responsible for fostering sustainable communities. The implications of the findings for future research are also considered.  相似文献

The relationship between western multinational corporations' perceived commercial interests and democratic quality in developing markets is more varied than habitually argued. While autocratic policy making and low-intensity democracy have been judged to provide benefits to investors, they are also increasingly recognized to generate features prejudicial to commercial operations. Many investment trends reflect the adverse impact of democratic limitations in developing markets. Multinational companies can be faulted less for a uniform effort to frustrate democratic improvements than for a failure to develop a coherent or proactive engagement in relation to the international democracy promotion agenda.  相似文献
