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

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane. 相似文献

This article provides a case study of the Victorian Women on Farms Gatherings (WOFG) to redress the lack of attention political historians have paid to farm women. Using materials collected by Museum Victoria, we trace the reasons for farm women's activism during the latter part of the twentieth century, and document the activities and outcomes of the Gatherings held annually since 1990. Our study demonstrates that farm women see politics as multi-faceted and heterogeneous. In short, there are no clear binaries between the political and non-political. This demonstrates the need to avoid masculinist and conventional definitions of politics, which obscure the political activities of women. Politics should not be conceptualised in a manner which associates women as a group with informal and non-traditional political activity. This simply reinscribes the types of binaries that have encouraged the omission of women from political history. 相似文献

Despite the entry into force of the Kyoto Protocol, the US decision not to comply with its Kyoto commitments seems to drastically undermine the effectiveness of the Protocol in controlling GHG emissions. Therefore, it is important to explore whether there are economic incentives that might help the US to modify its current decision and move to a more environmentally effective climate policy. For example, can an increased participation of developing countries induce the US to effectively participate in the effort to reduce GHG emissions? Is a single emission trading market the appropriate policy framework to increase the signatories of the Kyoto Protocol? This paper addresses the above questions by analysing whether the participation of China in the cooperative effort to control GHG emissions can provide adequate incentives for the US to re-join the Kyoto process and eventually ratify the Kyoto Protocol. This paper analyses three different climate regimes in which China could be involved and assesses the economic incentives for the major world countries and regions to participate in these three regimes. The main conclusion is that the participation of the US in a climate regime is not likely, at least in the short run. The US is more likely to adopt unilateral policies than to join the present Kyoto coalition (even when it includes China). However, a two bloc regime would become the most preferred option if both China and the US, for some political or environmental reasons, decide to cooperate on GHG emission control. If the US decides to cooperate, the climate regime that provides the highest economic incentives to the cooperating countries is the one in which China and the US cooperate bilaterally, with the Annex B?US countries remaining within the Kyoto framework. 相似文献

This paper develops an analytical framework tointegrate static and dynamic effects of theoreticallyrelevant and practically applied investment-decisioncriteria on the marginal rate of substitution betweeninvestment and labour. The new propositions are relatedto the ranking of relative present value, Kalecki'sindex of efficiency and the static version ofrecoupment period criteria. Investors in post-communisteconomies have switched from the recoupment period tothe criteria based on discounting. This is aninstitutional change typical for these economies. Itimplies a choice of techniques with lower investmentintensity, which is best supported by government'spolicy to promote labour mobility. 相似文献
