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

ABSTRACTLike many Republican presidential candidates before him, Donald J. Trump campaigned on a pro-business, anti-regulation platform, and since his election in November 2016, he has directed his administration to move forward with deregulation in many arenas, including consumer financial protections, environmental controls, and workplace safety among others. Past efforts to roll back regulations governing certain industries, such as the savings and loan and the mortgage industries, have had harmful consequences for the general public or for specific interest groups. In this study, we review what the Trump administration has accomplished with regard to deregulation to date. Then, based on past deregulatory fiascos, we theorize the harmful collateral consequences that may result from this most recent swing of the regulatory-deregulatory pendulum. 相似文献

ABSTRACTRecently, “problem-solving” courts have been developed as an alternative to imprisonment. They are often called “specialty” courts because they process and divert into treatment programs offenders who are seen as different from the general criminal population, such as those with mental health or drug problems, those who are homeless or veterans, and those who engage in domestic violence. Based on a 2017 national survey of 1,000 respondents, the current study examines overall public support for rehabilitation as a goal of corrections and then focuses specifically on support for different types of specialty courts. The analysis reveals that the American public endorses not only the rehabilitative ideal but also the use of problem-solving courts. Further, with only minimal variation, strong support for these courts appears to exist regardless of political orientation and sociodemographic characteristics. 相似文献

The decision to go to war in Australia remains the prerogative of the Executive. The lack of parliamentary authorisation of perhaps the most significant decision a democracy can make has seen sustained, but unsuccessful, efforts to reform legislation. In the wake of the costly invasion and occupation of Iraq in 2003, repeated calls for legislative reform of Australia's war powers have failed to find traction amongst Coalition and Australian Labor Party (ALP) leadership. Lamenting the lack of transparency and accountability in the current system, those favouring legislative reform would see authorisation of combat missions placed in the hands of Parliament. However, given the lack of support from either of the major parties, any legislative reform remains unlikely. Given this impasse, this article argues that a compromise option, in the form of a new war-powers convention, may be a small step towards democratising the decision of going to war. While not legally binding, this constitutional convention would represent an agreement by the major parties that overseas combat operations will be properly debated in Parliament. 相似文献

Sport's transformative potential is known to support marginalised children, to deal with traumatic experiences and instil positive values; yet hosting mega sporting events (MSEs) can have negative impacts. Drawing on participatory research with favela‐based children during the 2014 World Cup in Brazil, this article argues that MSEs bring a macro‐securitisation of urban life, which causes considerable harm. This paper also suggests that the inclusion of children's voices in advocacy debates can challenge top‐down securitisation and might allow MSEs to foster further positive social transformation. Therefore, juxtaposed with causing harm, macro‐securitisations can open opportunities for children to take action and have their voices heard. 相似文献
