This investigation intends to study materials and techniques used for biological evidence collection in sexual assault cases and is divided into two stages: in stage one, methods for biological evidence collection (the single swab (including three variants) and the “double swab technique”) were compared; in stage two, swabs’ component material was compared. The sampling was composed of 42 heterosexual couples who provided mock samples. The collection methods in which the whole swab is covered by evidence presented significantly better outcomes (p < 0.001), such as the “double swab technique.” Additionally, nylon swabs proved to present significantly better features regarding the capacity of sample elution, providing significantly higher amounts of DNA (p ≤ 0.034). This study provides guidelines for better collection of biological evidence regarding the collection method using a swab and the proper swab material to utilize. 相似文献

Population frequencies for the eight Y-STR loci included in the "minimal haplotype" from Y-STR Haplotype Reference Database (YHRD) plus other eight Y-STRs (DYS434, DYS435, DYS436, DYS437, DYS438, DYS439, GATA H4 and GATA A10) were obtained for a sample of 133 males from four main geographical areas in the Pyrenees (Spain): Vall D'Aran (Lérida), Cerdanya (Gerona), Alt Urgell (Lérida) and Jacetania (Huesca). Haplotype diversities were estimated in the four populations. 相似文献

Despite there having been a positive context for initiating health care reforms in Portugal in the past fifteen years (accompanied by political consensus on the nature of the structural problems within the health care system), there has been a lack of reform initiatives. We use a process-based framework to show how institutional arrangements have influenced Portuguese health care reform. Evidence is presented to demonstrate inertia and nondecision making in three critical areas of Portuguese health policy: clarifying the public-private mix in coverage and provision, creating financial incentives and motivation for human resources, and introducing changes in the pharmaceutical market. Several factors seem to explain these processes, namely, problems in the balance of power within the political system, which have contributed to a lack of proper policy discussion; a lack of pluralism in the formation of health care policies (with low participation from citizens and high mobilization among structural interest groups); and the low priority of health care in public sector reforms. Portuguese politicians should be aware of the pitfalls of the current political system that constrain participatory arrangements and pluralism in policy making. In order to pursue health care reform, future governments will need to counterbalance the strong influence of structural interest groups. 相似文献

Allele frequencies for seventeen STRs included in the AmpF/STR Identifiler (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPOX, and VWA) and Powerplex 16 System (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, TH01, TPOX, and VWA) were estimated from a sample of 110 unrelated individuals from Cabinda, Angola. Comparative analyses between our population data and other African databases, namely Promega's African-Americans, AB Applied Biosystems African-Americans and five other population samples gathered from the literature are also presented. 相似文献

Auf der Grundlage des akteurzentrierten Institutionalismus präsentiert der vorliegende Beitrag eine theoriegeleitete und empirisch angereicherte Analyse von Verhandlungsergebnissen in der EU am Beispiel der Gemeinsamen Fischereipolitik. Dabei fasst das zugrunde liegende Untersuchungsdesign die Verhandlungsergebnisse als die abhängige, die Präferenzen der Mitgliedstaaten, die Präferenzen der Kommission sowie den institutionellen Rahmen als die unabhängigen Variablen auf. Dieses Untersuchungsdesign wird dann empirisch an zwei wichtigen Verhandlungssituationen überprüft, die gleichzeitig mit der Kompetenzübertragung der Fischereipolitik auf die europäische Ebene einhergehen. In der ersten Verhandlungssituation geht es um die Einführung der Strukturpolitik und der Gemeinsamen Marktorganisation für den Fischereisektor im Jahr 1970. Bei der zweiten Verhandlungssituation steht die Einführung der Bestanderhaltungspolitik für die Fischbestände im Jahr 1983 im Mittelpunkt. Zusätzlich zu den Verhandlungspositionen der Regierungen der Mitgliedstaaten wird in diesem Beitrag anhand der Rolle der Kommission und der formellen (Einstimmigkeitsprinzip) und informellen Regeln (Schatten der Zukunft) gezeigt, wie sich diese Variablen auf die Politikergebnisse auswirken. 相似文献

Allele and haplotype frequencies of 17 chromosome STR loci, 15 of them included in the kit PowerPlex 16 System from Promega, were determined in a sample of unrelated males from Madeira and Porto Santo Islands. PowerPlex 16 includes STRs not studied before in the Madeira population. The-kit includes two new allele markers (Penta D and Penta E), which proved to be extremely useful for paternity testing (PD = 0.952 and 0.977, respectively). The study revealed that the Madeira population does not differ from that of the north Portugal. Nevertheless, some loci presented alleles found in sub-Saharan and North European populations which were not reported so far in Portugal. 相似文献

The effectiveness of crime deterrence projects such as increased street lighting in ghetto environments has been questioned. The present study not only examines whether increased street lighting in fact reduces crime, but also investigates the attitudes towards local government of citizens who live within that particular environment. The findings illustrate that it would be advisable for governments to address citizen attitudes before undertaking certain crime prevention projects. 相似文献
