Semaan et al. (J Forensic Res, 2020, 11, 453) discuss a mock case “where eight different individuals [P1 through P8] could not be excluded in a mixed DNA analysis. Even though … expert DNA mixture analysis software was used.” Two of these are the true donors. The LRs reported are incorrect due to the incorrect entry of propositions into LRmix Studio. This forced the software to account for most of the alleles as drop-in, resulting in LRs 60–70 orders of magnitude larger than expected. P1, P2, P4, P5, and P8 can be manually excluded using peak heights. This has relevance when using LRmix which does not use peak heights. We extend the work using the same two reference genotypes who were the true contributors as Semaan et al. (J Forensic Res, 2020, 11, 453). We simulate three two-donor mixtures with peak heights using these two genotypes and analyze using STRmix?. For the simulated 1:1 mixture, one of the non-donors’ LRs supported him being a contributor when no conditioning was used. When considered in combination with any other potential donors (i.e., with conditioning), this non-donor was correctly eliminated. For the 3:1 mixture, all results correctly supported that the non-donors were not contributors. The low-template 4:1 mixture LRs with no conditioning showed support for all eight profiles as donors. However, the results from pair-wise conditioning showed that only the two ground truth donors had LRs supporting that they were contributors to the mixture. We recommend the use of peak heights and conditioning profiles, as this allows better sensitivity and specificity even when the persons share many alleles.  相似文献

This paper draws on recent research examining feminist and everyday geopolitics to focus on the relatively neglected domestic sphere as a space where geopolitical events like the Falklands/Malvinas war are learnt, (re)produced, remembered and contested by young people. It presents qualitative data drawn from interviews with young people from Argentina (Río Gallegos) and the Falkland Islands (Stanley), locations with intimate connections to the 1982 war. It argues that research in domestic environments that engages the familial relations, objects and practices that embody geopolitical pasts can help make sense of how young people (are able to) express geopolitical agency.  相似文献

Qualitative interviews with one hundred defendants in Dutch criminal cases examine whether perceived procedural justice is a relevant concern for defendants, and, if so, which procedural justice components they refer to. The study provides a point of epistemological departure from the quantitative studies dominating the field, as it assessed which components of procedural justice (if any) respondents put forward themselves rather than asking about predetermined procedural justice components. The large majority of respondents mentioned procedural justice issues themselves, and six components were at the core of their procedural justice perceptions: (1) information on which decisions are based, (2) interpersonal treatment, (3) due consideration, (4) neutrality, (5) voice, and (6) accuracy. Although these procedural justice components largely correspond with the literature, respondents thus mentioned some components more often, and others less often, than the literature would suggest. In particular, neutrality plays an important role in the Dutch legal context examined here.  相似文献

Professions are granted a form of cartel that enables them to charge more than would arise in a free market on the assumption that they provide better quality and are more trustworthy than free-market actors would be. The theoretical assumption that lawyers are more competent than nonlawyers has given rise to significant formal protections for professions in many jurisdictions. Two testable propositions arise from this theory: (1) lawyers cost more, but (2) they deliver higher quality. It is a testing of these twin propositions that is the subject of this article, with well-triangulated data and a deeper understanding of the theoretical differences between lawyers and nonlawyers.  相似文献

Acute myoglobinuria as a fatal complication of heroin addiction   总被引:3,自引:0,他引:3  
A fatal case of myoglobinuria complicating heroin addiction is described. Clinically the patient had no overt symptoms of rhabdomyolysis. Pathologists should be alerted to this rare complication in heroin addicts who die of no apparent cause. The antimyoglobin immunoperoxidase technique is useful in confirming the diagnosis.  相似文献

Stab wounds were made in parenchymatous organs (e.g. liver, spleen, kidneys, lungs) using a variety of instruments. The shape of the resulting canal was investigated by X-ray analysis after introduction of an X-ray contrast medium. The best contrast was obtained using a contrast medium containing barium. The shape of the canal gave a direct representation of the outline of the instrument used. The width of the canal was however, always several millimeters smaller than the corresponding blade of the instrument. The position of the blade back in single-edged blades could be demonstrated with stronger contrast.  相似文献
