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.     

Bringing the Falklands/Malvinas Home: Young People's Everyday Engagements with Geopolitics in Domestic Space

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.     

Speaking of Justice: A Qualitative Interview Study on Perceived Procedural Justice Among Defendants in Dutch Criminal Cases

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.     

Contesting Professionalism: Legal Aid and Nonlawyers in England and Wales

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.     

Acute myoglobinuria as a fatal complication of heroin addiction

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.     

When ADR becomes the law: A review of federal practice

Conclusion With the passage of the Administrative Dispute Resolution Act, the stage was set for innovation and change in federal agencies. Now, part way into the five-year life of the Act, a new administration has the potential to encourage even wider use of ADR at the federal level, providing still more examples from which to develop a clearer sense of best practice. Additional funds, both for ACUS and individual agencies, are vital to providing the level of experimentation, innovation, and documentation needed to ensure success.MIT ProfessorLawrence E.

Correlates of Mortality in a U.S. Cohort of Youth, 1980–98: Implications for Social Justice

This paper reports results of a study based on a nationally representative sample of U.S. youth (N = 11,549) that asked two questions: (1) How does family structure affect the likelihood of adolescent death beyond that of race/ethnicity, sex, socioeconomic status, personal behavior, and other structural factors and (2) under what conditions might appeals for social justice be warranted for relative mortality statuses and for absolute gains in mortality? The study found that marital instability increases the likelihood of dying when controlling for a variety of other factors including class, race/ethnicity, sex, and unemployment rate in area of residence. The author argues that this finding lends support to social justice arguments to redistribute resources in such a way as to ensure the likelihood of absolute gains in mortality. The study also found, however, that race/ethnicity/sex also accounted for the likelihood of dying independently of family structure when controlling for socioeconomic and other factors. The author argues that this finding lends support to social justice arguments to redistribute resources on the basis of relative mortality statuses.     

A LOG‐MULTIPLICATIVE ASSOCIATION MODEL FOR ALLOCATING HOMICIDES WITH UNKNOWN VICTIM‐OFFENDER RELATIONSHIPS*

This research note critically evaluates conventional methods for allocating homicides with an unknown victim/offender relationship to meaningful categories, and it proposes an alternative approach. We argue that conventional methods are based on a problematic assumption, namely, that the missing data mechanism is “ignorable.” As an alternative to these methods, we propose an imputation algorithm derived from a log‐multiplicative model that does not require this assumption. We apply this technique to estimate levels of homicides disaggregated by victim/offender relationship using the Federal Bureau of Investigation's Supplementary Homicide Report (SHR) data for 1996 and 1997, and we compare the resulting estimates with those obtained from the application of conventional procedures. Our results yield a larger proportion of stranger homicides than are obtained from the conventional methods.
