A mixed DNA profile controversy revisited

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.     

Not Dead Yet? Explaining Party Member Activity in Germany

While political parties in Germany have been steadily losing members for more than two decades, there has been no sign of a breakdown in their day-to-day grass-roots activities. Despite many prophecies of doom, the ‘party on the ground’ does not seem to be dead yet. There is some evidence that the declining number of party members is compensated for by an increasing share of party activists. The question is how the erosion of the political parties’ member-ship base affects their levels and types of activity. This paper aims to describe and explain these two dimensions of activity in German political parties, using data from German party membership studies from 1998 and 2009. The analyses show that parties are partly able to compensate for membership losses via an increased activity of the remaining members, but at the same time, it is possible that changes in the social profile and motivations of the most active group of members may lead to future difficulties in coping with party work and canvassing new members.     

New Zealand lawyers and conveyancers disciplinary tribunal cases involving vulnerable clients, 2011–2017*

ABSTRACT

This research analyses disciplinary decisions of the New Zealand Lawyers and Conveyancers Disciplinary Tribunal (NZLCDT) from 2011 to 2017 that involve vulnerable clients. Increasingly, scholarship discusses vulnerability as an ethical concept, including in the legal context. Based on published decisions, the present study inquires whether some legal clients’ vulnerability warrants special attention. Twenty-five of the 193 clients in the NZLCDT decisions qualified as vulnerable based upon age, gender, mental health/neuro-disability or immigrant status. The results may inform disciplinary bodies and inspire preventive strategies by lawyers, educators and regulatory bodies. Ultimately, this evidence-based analysis magnifies the importance of client-centred approaches to risk reduction in legal practice.     

Criticizing the image of the student as consumer: examining legal trends and administrative responses in the US and UK1

There is widespread concern that higher education is being compromised by being turned into a ‘commodity’ to be ‘consumed’. This article represents an initial attempt to explore the trends in both the UK and US, and considers how the law has responded to them. It argues, however, that there is an important distinction to be drawn between ‘commodification’ and ‘consumerism’. Education has always been a commodity to be bought and sold; the true danger lies in the move to a ‘rights-based’ culture where students (and politicians) see education merely as something to be ‘consumed’ rather than as an activity in which to participate. Whilst the law seems thus far to have been something of a bulwark against this movement, it remains an open question as to whether this will continue to be the case if HEIs do not themselves act more proactively in challenging this damaging view of higher education.     

Chapter 2: Pay Now So You Won't Pay Later: The Effectiveness of Prevention Programming in the Fight to Reduce Delinquency

Community-based delinquency prevention programs, designed to work with youth and families before they become involved with the official court process, are relatively rare. Likewise, few studies have been published concerninge valuative research on such programs. This article reviews some background on program concepts, describes the operations of the Oakland County Probate Court Youth Assistance casework services program, and reports the results of a comprehensive program evaluation project. The findings suggest that prevention programming is one effective strategy to aid in reducing the likelihood of more costly court interventions. Recommendations for program development are offered.     

Determination of cocaine and benzoylecgonine in human amniotic fluid using high flow solid-phase extraction columns and HPLC.

A new solid-phase extraction procedure for the determination of cocaine and benzoylecgonine in amniotic fluid, using high flow co-polymeric sorbents is reported. The recoveries of cocaine and benzoylecgonine within the range 0.1-1 mg/l were 95.7% and 50.3%, respectively. The use of high-flow sorbents allowed the easy extraction of amniotic fluid regardless of sample viscosity or physical nature. The use of these solid-phase columns provided many advantages over the more commonly used solvent extraction, including an increase in extraction speed and efficiency, reduced operator time, reduced solvent use and disposal volumes and exceptional extract quality. Further, the determination of amniotic fluid obtained from pregnant cocaine users may provide important information about handling of cocaine by the fetus at various gestational ages. The procedure was successfully applied to amniotic fluid from suspected cocaine abusers.
