Fimag: The United Kingdom Disaster Victim/Forensic Identification Imaging System

Abstract:  Imaging is an integral diagnostic tool in mass fatality investigations undertaken traditionally by plain X-rays, fluoroscopy, and dental radiography. However, little attention has been given to appropriate image reporting, secure data transfer and storage particularly in relation to the need to meet stringent judicial requirements. Notwithstanding these limitations, it is the risk associated with the safe handling and investigation of contaminated fatalities which is providing new challenges for mass fatality radiological imaging. Mobile multi-slice computed tomography is an alternative to these traditional modalities as it provides a greater diagnostic yield and an opportunity to address the requirements of the criminal justice system. We present a new national disaster victim/forensic identification imaging system—Fimag—which is applicable for both contaminated and non-contaminated mass fatality imaging and addresses the issues of judicial reporting. We suggest this system opens a new era in radiological diagnostics for mass fatalities.     

Canine Population Data Generated from a Multiplex STR Kit for Use in Forensic Casework*

Abstract: Canine biological specimens are often part of the physical evidence from crime scenes. Until now, there have been no validated canine‐specific forensic reagent kits available. A multiplex genotyping system, comprising 18 short tandem repeats (STRs) and a sex‐linked zinc finger locus for gender determination, was developed for generating population genetic data assessing the weight of canine forensic DNA profiles. Allele frequencies were estimated for 236 pedigreed and 431 mixed breed dogs residing in the U.S. Average random match probability is 1 in 2 × 10³³ using the regional database and 1 in 4 × 10³⁹ using the breed dataset. Each pedigreed population was genetically distinct and could be differentiated from the mixed breed dog population but genetic variation was not significantly correlated with geographic transition. Results herein support the use of the allele frequency data with the canine STR multiplex for conveying the significance of identity testing for forensic casework, parentage testing, and breed assignments.     

Distribution of 6-monoacetylmorphine and morphine in head and pubic hair from heroin-related deaths

There is limited published data to aid interpretation of analytical findings from hair analysis. The aim of the study was to collate 6-monoacetylmorphine (6-AM) and morphine concentrations in head and pubic hair from heroin users and to propose reference ranges and relate these to the amount of heroin used. The ratio of morphine-to-6-AM was also investigated. A total of 82 head hair samples divided into 173 segments of various lengths and 15 pubic hair samples were collected at postmortem from heroin users. The hair was analysed using a previously published method. A statistical evaluation demonstrated that in head hair, the lower, middle and upper concentration ranges of 6-AM were 0.1–0.9, 0.9–12.5 and 12.5–154.1 ng/mg and those of morphine were 0.1–0.8, 0.8–6.0 and 6.0–36.3 ng/mg. In pubic hair, the lower, middle and upper concentration ranges of 6-AM were 0.2–0.5, 0.5–2.3 and 2.3–18.2 ng/mg and those of morphine were 0.2–0.4, 0.4–2.4 and 2.4–13.3 ng/mg. The morphine-to-6-AM ratio showed a large variation. The ratio tended to decrease from proximal to distal segments. The statistical results suggest low, middle and high concentration ranges which we propose can be used for estimating the amount of heroin consumed into corresponding low or occasional, regular or habitual and heavy or excessive drug use. The ratio of morphine-to-6-AM showed great variation and did not support the proposal that a ratio less than 0.77 is needed to prove ingestion of heroin.     

A Strategic Left? Starmerism,Pluralism and the Soft Left

This article places the Labour Party’s present post‐Corbyn renewal in the context of previous periods of renewal in the party’s recent history, associating with the new leadership of Keir Starmer a potential to rediscover the strategic project of the pluralist soft left as an alternative to the programmatic character of the hard left. After assessing the Corbynist hegemony established in the Labour Party between 2015 and 2019, it considers the current absence of any clearly defined set of principles or values underpinning ‘Starmerism’. It then looks back to the Kinnockite ascendency in the 1980s, and the Blairite ascendency in the 1990s, as possible templates for how the party reassesses its positioning with reference to changing electoral, social and economic circumstances. A critique of Corbynism’s left populism culminates in a consideration of the possible grounds for a new pluralist agenda attuned to the policy and electoral challenges Labour faces today.     

How Cross‐Examination on Subjectivity and Bias Affects Jurors’ Evaluations of Forensic Science Evidence

Contextual bias has been widely discussed as a possible problem in forensic science. The trial simulation experiment reported here examined reactions of jurors at a county courthouse to cross‐examination and arguments about contextual bias in a hypothetical case. We varied whether the key prosecution witness (a forensic odontologist) was cross‐examined about the subjectivity of his interpretations and about his exposure to potentially biasing task‐irrelevant information. Jurors found the expert less credible and were less likely to convict when the expert admitted that his interpretation rested on subjective judgment, and when he admitted having been exposed to potentially biasing task‐irrelevant contextual information (relative to when these issues were not raised by the lawyers). The findings suggest, however, that forensic scientists can immunize themselves against such challenges and maximize the weight jurors give their evidence by adopting context management procedures that blind them to task‐irrelevant information.

Afterword: turning and twisting histories of women’s education: reading reflexively and diffractively

ABSTRACT

The Afterword discusses continuities and differences in how researchers are positioned in feminist themes and emerging feminist perspectives as they play out in debates around researcher reflexivity and diffraction as methodological strategies. The first section of the Afterword highlights the ongoing commitment to reflexivity when generating knowledge in women’s and gender history. The second part focuses on the challenge to reflexivity posed by diffractive methodologies that argue that knowledge is created from being entangled in the world, rather than reflecting on or during the production of historical work. This section discusses two examples of diffractive practice in archival research taken from the special issue. The third section outlines diffractive reading in more detail and provides two examples of diffractive reading of texts. Finally, the Afterword invites readers to undertake a diffractive reading of the articles in the special issue and provides some questions about diffraction for consideration.     

Service providers' reactions to intimate partner violence as a function of victim sexual orientation and type of abuse

In this online vignette study, a national sample of domestic violence shelter service providers (N = 282) completed a 10-item questionnaire about a woman experiencing intimate partner violence (IPV). Scenarios varied in terms of couple sexual orientation (heterosexual or lesbian) and type of abuse (physical or nonphysical). Results indicate that although participants did not overtly discriminate against a woman in a lesbian relationship, they were less likely to perceive her as a victim, and their acceptance of a lesbian as a client was more dependent on their comfort with her than was the case for a woman in a heterosexual relationship. Type of abuse, as expected, had a main effect on many questions, with physical abuse taken more seriously than nonphysical abuse. Scores on the Attitudes Toward Lesbians subscale (Herek) were unrelated to responses. Implications for service providers are discussed.
