Currently, aluminum stub with carbon adhesive devices are used to collect inorganic gunshot residues (GSR) from the hands of a shooter. In an ideal shooting case, the gunshot particles do not persist for more than 2 h in the hands of the shooter, provided that the hands have not been washed. However, for forensic analysis and inference, the extended persistence of GSR would be desirable. This study investigates a novel GSR sampling and detection protocol. Sampling was performed in the nostrils using swab devices impregnated in ethylenediaminetetraacetic acid (EDTA). The GSRs persisted for longer periods in nasal mucus than on the hands, and particles were detected 6 h after shooting occurred. The analytical determination was conducted by scanning laser ablation-inductively coupled plasma-mass spectrometry (SLA-ICPMS) which enable the identification of the number of particles and their elemental composition. Seventeen isotope signals corresponding to 13C, 205Tl and 15 analytes that are usually associated with the composition of GSR residues were monitored: 27Al, 29Si, 31P, 33S, 35Cl, 39K, 44Ca, 57Fe, 60Ni, 63Cu, 66Zn, 118Sn, 121Sb, 137Ba, and 208Pb. The SLA technique enabled the reduction of the swab analysis time to 40 min. The effectiveness of this methodology was evaluated with two types of firearms: a pistol and a shotgun. The results indicated that the methodology proposed for the analysis of the nasal GSR was effective and that it can improve or complement the forensic analyses and inferences presented in a court. 相似文献

ABSTRACTNowadays legislatures are largely based on committee systems. This enables a division of work and specialisation, in the context of highly complex politics and policy development. It seems clear that MP specialisation in the field of the committee they serve on is an important political asset, both for MPs and their parliamentary party group. This paper presents the Committee Parliamentary Specialization Index. This index measures the degree an MP is specialised in the jurisdiction of the committee they serve on. In the second part of the paper, the index is applied to the Spanish Congreso de los Diputados, an interesting case for testing this multi-faceted index, to find institutional, political and individual factors that better explain the degree of MP specialisation. 相似文献

The aim of this paper was to analyze equity market reactions to the mandatory European Union regulation of remuneration policies in financial institutions. Using event study methodology, we investigated market reactions to the first European Directive on compensation policies after the financial crisis using a sample of 124 banks operating in the European Union. We divided the sample into two groups according to bank size considering four criteria: the US Dodd‐Frank Act 2010, the Liikanen Report 2012, Global Systemically Important Banks 2011, and the European Central Bank 2014. We found strong evidence of an average negative market reaction to compensation regulation. Moreover, this negative reaction is stronger for large banks than for small/medium sized banks. 相似文献

This paper attempts to vindicate the part played by certain Spanish aristocratic women in the management, conservation, and transmission of their artistic patrimony in the decades around the turn of the twentieth century by creating art collections and displaying them in their own homes. The works were exhibited in rooms that were decorated and furnished to suggest historical ambiences in which French trends rubbed shoulders with styles that had been developed in Spain throughout its history, turning their homes into devices that recreated past times. Similarly, retrospective views of Spanish art were the focus of leisure and entertainment activities driven by ladies from the upper echelons of society through the performance of tableaux vivants. The focus of this study will be Trinidad Scholtz Hermensdorff, Duchess of Parcent. 相似文献

This study fills a gap in the literature in regards to the effectiveness of youth diversity programs by exploring the sustaining effects of a week-long youth diversity camp program. Using both qualitative and quantitative methods, the study results suggest the camp achieved positive, sustaining impacts. Some of these findings include (1) enhancement of leadership skills; (2) greater understanding of “the other”; and (3) increased communication skills, particularly when oppression was observed. These effects were observed in the respondents who had recently attended the camp, as well as those who had attended a long time prior. Such impact reported in the study reiterates that more diversity programs for youth should be developed, implemented, and evaluated. 相似文献
