We report here a review of the seventh mitochondrial DNA (mtDNA) exercise undertaken by the Spanish and Portuguese working group (GEP) of the International Society for Forensic Genetics (ISFG) corresponding to the period 2003-2004. Five reference bloodstains from five donors (M1-M5), a mixed stain of saliva and semen (M6), and a hair sample (M7) were submitted to each participating laboratory for nuclear DNA (nDNA; autosomal STR and Y-STR) and mtDNA analysis. Laboratories were asked to investigate the contributors of samples M6 and M7 among the reference donors (M1-M5). A total of 34 laboratories reported total or partial mtDNA sequence data from both, the reference bloodstains (M1-M5) and the hair sample (M7) concluding a match between mtDNA profiles of M5 and M7. Autosomal STR and Y-STR profiling was the preferred strategy to investigate the contributors of the semen/saliva mixture (M6). Nuclear DNA profiles were consistent with a mixture of saliva from the donor (female) of M4 and semen from donor M5, being the semen (XY) profile the dominant component of the mixture. Strikingly, and in contradiction to the nuclear DNA analysis, mtDNA sequencing results yield a more simple result: only the saliva contribution (M4) was detected, either after preferential lysis or after complete DNA digestion. Some labs provided with several explanations for this finding and carried out additional experiments to explain this apparent contradictory result. The results pointed to the existence of different relative amounts of nuclear and mtDNAs in saliva and semen. We conclude that this circumstance could strongly influence the interpretation of the mtDNA evidence in unbalanced mixtures and in consequence lead to false exclusions. During the GEP-ISFG annual conference a validation study was planned to progress in the interpretation of mtDNA from different mixtures. 相似文献

This article compares Canadian treatment of corporate criminal liability with that in Brazil, examining whether there are ways in which one system can learn from the other. It is argued that the Canadian model could provide a starting point for revision of Brazilian legal principles in this area that, would encourage the public to recognize that crimes committed by corporations should be taken seriously. However, because criminal liability requires a high burden of proof and is therefore difficult to secure, the Brazilian regime of strict liability may ultimately be useful in encouraging compliance by corporations, assuming sanctions are severe enough and detection of violations by law enforcers is enhanced. The solution may therefore consist in the use of both these regimes, as is currently the case with anticorruption law in the UK. 相似文献

One of the most important contributions of forensic entomology is to assist criminal expertise to determine the postmortem interval, which depends on the duration of the immature stages of insects of forensic interest. On the other hand, the time of development of the different stages varies according to the species; therefore, its identification is essential. Currently, few studies have investigated the use of cuticular hydrocarbons, and none regarding fatty acids, as complementary taxonomic tools to expedite species identification. Therefore, we evaluated whether cuticular hydrocarbons together with fatty acids of eggs of flies of the family Calliphoridae, main group of forensic interest, can be used to distinguish species. The analyses were performed by chromatographic techniques. The results show that there are significant differences between the composition of cuticular hydrocarbons and fatty acids between species and, therefore, they can be used to provide a complementary taxonomic tool to expedite the forensic expertise. 相似文献

This article provides the background to an international project on use of force by the police that was carried out in seven
countries. Force is often considered to be the defining characteristic of policing and much research has been conducted on
the determinants, prevalence and control of the use of force, particularly in the United States. However, little work has
looked at police officers’ own views on the use of force, in particular the way in which they justify it. Using a hypothetical
encounter developed for this project, researchers in each country conducted focus groups with police officers in which they
were encouraged to talk about the use of force. The results show interesting similarities and differences across countries
and demonstrate the value of using this kind of research focus and methodology.

The article explains the Argentine-Chinese economic relations and identifies the interest’s network with the ongoing modernization processes in both countries. It can be observed that harmony is more important than discord when Argentina accepts the new China’s international division of labor, but when Argentina tends to consolidate the process of economic de-primarization, tensions between both countries tend to emerge. The crisis about crude soybean oil in 2010 is the clearest example to illustrate that trade tensions between both countries will be most frequent if Argentine industrialization continues and the process of policy coordination fails. 相似文献

AbstractThe aim of this article is to distinguish between two levels of collective memory in Lebanon: the national memory, which is a very weak and fragile memory, and the communal memory of sectarian groups. Each community in Lebanon enjoys a memory of its own, which it tries to elevate to the national memory, but at the same time intra-sectarian groups contest their internal memories with others. Hence, we see that communities try to force the state to adopt their respective memories, while internally groups tend to eliminate their competitor’s memory and communal narrative. 相似文献

The COVID-19 pandemic has created a crisis that is challenging national and local governments to innovate in their responses to novel problems. Despite similarities to the challenges confronted in developed countries, for Latin American governments, these problems are amplified by structural obstacles such as social inequalities. These countries must respond with capacities and resources that are often limited by spoils systems and by social and political polarization. This essay provides an overview of some innovative practices in Argentina, Brazil, Chile, Colombia, and Mexico. In particular, this essay concentrates on some salient collaborative efforts in the region. To draw lessons from these practices, the authors focus on the formal and informal institutions that facilitate or obstruct collaboration across jurisdictions. The findings are discussed in terms of the transaction costs of collaboration identified in these experiences. 相似文献

This article describes the autopsy findings of a victim of a shark attack that took place off the coast of Pernambuco, Brazil. The victim was rescued and immediately taken to a nearby hospital but did not survive, even though the lapse of time between the attack and verification of death did not exceed 15 minutes. The presence of a single, large, contused and incised, semiarched wound with a serrated aspect was decisive in elucidating the event. Thus, this study discusses aspects related to the aggressor species, to the autopsy, to the type of wound, and to the causes that have led to a significant increase in this type of event in the area. It was concluded that the lesion was produced while the victim was still alive and that it was the cause of death. 相似文献
