Effect of Head Position on Facial Soft Tissue Depth Measurements Obtained Using Computed Tomography

Facial soft tissue depth (FSTD) studies employing clinical computed tomography (CT) data frequently rely on depth measurements from raw 2D orthoslices. However, the position of each patient's head was not standardized in this method, potentially decreasing measurement reliability and accuracy. This study measured FSTDs along the original orthoslice plane and compared these measurements to those standardized by the Frankfurt horizontal (FH). Subadult cranial CT scans (n = 115) were used to measure FSTDs at 18 landmarks. Significant differences were observed between the methods at eight of these landmarks (p < 0.05), demonstrating that high‐quality data are not generated simply by employing modern imaging modalities such as CT. Proper technique is crucial to useful results, and maintaining control over head position during FSTD data collection is important. This is easily and most readily achieved in CT techniques by rotating the head to the FH plane after constructing a 3D rendering of the data.     

Postmortem Concentration and Redistribution of Diazepam,Methadone, and Morphine with Subclavian and Femoral Vein Dissection/Clamping

Postmortem redistribution (PMR) concerns blood drug concentration variations after death, depending on many factors such as sampling site and technique. In our study, we focused on sampling method. 30 cases were sampled, each at cardiac, subclavian, femoral, and popliteal sites. Targeted substances were diazepam, methadone, and morphine. Blind stick and dissection/clamping techniques were concomitantly performed at subclavian and femoral sites. Subclavian and femoral concentrations were compared according to technique used. To assess the influence of sampling technique on PMR, central/peripheral ratios were calculated depending on sampling method. Results show that drug concentrations tend to be lower when drawn from a clamped subclavian or femoral vein whereas ratios including subclavian and/or femoral blood concentration are influenced according to the technique used. In conclusion, clamping a subclavian or femoral vessel before sampling tends to result in lower drug concentrations and may influence ratios, suggesting the importance of isolating vessels from thoraco‐abdominal viscera.     

Sexual Citizenship in the European Union

This article examines two different uses of the language of citizenship: in the context of the 'sexual citizen', and the transnational 'European citizen' of European Union politics. It begins with an exploration of how the concept of citizenship has been constitutively built on a set of binary constructs of in/exclusion and can prove a disciplining and regulatory concept. Yet, simultaneously, citizenship can have an active and democratic potentiality. The article interrogates these two faces of citizenship by considering the mobilization of lesbians and gay men through the International Lesbian and Gay Association Europe (ILGA Europe), and the engagement of ILGA with the institutions of the European Union. The article concludes that European and sexual citizenship underscores the tension, not only between active and passive citizenship forms, but more generally, between identity and difference. This tension demands, in turn, a reappraisal of identity-based thinking, in favour of a more coalitional, affinity-based politics .     

The potential to determine a postmortem submersion interval based on algal/diatom diversity on decomposing mammalian carcasses in brackish ponds in Delaware

Recently botanical evidence has been studied to determine if it is useful in forensic investigations. This study was performed to examine stillborn piglet decomposition in a brackish water environment and to semi-quantitatively document stages of decomposition, degree day accumulation per stage as well as the algal/diatom diversity useful in determining a postmortem submersion interval (PMSI). Piglets and ceramic tiles were submerged in brackish ponds and sampled on a regular basis to document algal diversity and succession between substrates and stages of decomposition. Significantly greater weight was lost from piglet carcasses during the early floating and advanced floating decay stages. Seasonal effects were observed in degree-day accumulations. Diatom diversity was significantly greater on piglet carcasses compared to tile substrates. Algal diversity decreased over time on the piglet carcasses as well as the stage of decomposition. A significant relationship and strong correlation between algal diversity found on the piglet substrate with time was observed. Our results indicate that more research is needed to examine the potential to use diatoms in not only determining manner of death but also the duration of time (PMSI) a victim may have been immersed in an aquatic environment.     

Facial soft tissue depths in craniofacial identification (part I): An analytical review of the published adult data

With the ever increasing production of average soft tissue depth studies, data are becoming increasingly complex, less standardized, and more unwieldy. So far, no overarching review has been attempted to determine: the validity of continued data collection; the usefulness of the existing data subcategorizations; or if a synthesis is possible to produce a manageable soft tissue depth library. While a principal components analysis would provide the best foundation for such an assessment, this type of investigation is not currently possible because of a lack of easily accessible raw data (first, many studies are narrow; second, raw data are infrequently published and/or stored and are not always shared by some authors). This paper provides an alternate means of investigation using an hierarchical approach to review and compare the effects of single variables on published mean values for adults whilst acknowledging measurement errors and within-group variation. The results revealed: (i) no clear secular trends at frequently investigated landmarks; (ii) wide variation in soft tissue depth measures between different measurement techniques irrespective of whether living persons or cadavers were considered; (iii) no clear clustering of non-Caucasoid data far from the Caucasoid means; and (iv) minor differences between males and females. Consequently, the data were pooled across studies using weighted means and standard deviations to cancel out random and opposing study-specific errors, and to produce a single soft tissue depth table with increased sample sizes (e.g., 6786 individuals at pogonion).     

The relationship of stress, impulsivity, and beliefs to drug use severity in a sample of women prison inmates

There is a paucity of research examining substance abuse issues among women prisoners. This study explored relationships between perceived stress, impulsivity, and beliefs in the efficacy of drugs as these variables pertain to self-reported drug use severity. Women prisoners (N = 100) participated in structured face-to-face interviews based on established research instruments. Although there was no significant correlation between demographic characteristics and substance use severity, positive relationships were found between substance use severity, perceived stress, impulsivity, and beliefs. A multiple linear model was estimated regressing drug use severity on beliefs, impulsivity, and perceived stress. Only the measures of beliefs and impulsivity were significant correlates of drug use severity. Implications are discussed for prison substance abuse programming and future research.     

Patients as consumers: courts, contracts, and the new medical marketplace

The persistent riddle of health-care policy is how to control the costs while improving the quality of care. The riddle's once promising answer--managed care--has been politically ravaged, and consumerist solutions are now winning favor. This Article examines the legal condition of the patient-as-consumer in today's health-care market. It finds that insurers bargain with some success for rates for the people they insure. The uninsured, however, must contract to pay whatever a provider charges and then are regularly charged prices that are several times insurers' prices and providers' actual costs. Perhaps because they do not understand the healthcare market, courts generally enforce these contracts. This Article proposes legal solutions to the plight of the patient-as-consumer and asks what that plight tells us about market solutions to the health-care quandary.     

Gender-specific factors associated with community substance abuse treatment utilization among incarcerated substance users

This article describes the independent correlates of preincarceration community substance abuse treatment utilization for male and female offenders currently participating in prison-based treatment. As part of the National Institute on Drug Abuse-funded Criminal Justice Drug Abuse Treatment Studies cooperative agreement, this protocol was implemented by four collaborating research centers. Males with a history of treatment utilization were more likely to be older, to have used crack, and to have had a greater number of arrests, and they were less likely to be arrested for a violent charge. Females with previous treatment were more likely to have been hospitalized for a health condition and were significantly more likely to have lived with someone else before prison rather than in their own home. These findings suggest that factors associated with preincarceration treatment utilization differ by gender, which may have important implications for correctional-based treatment assessment, reentry planning, and transitional case management.     

An Evaluation of Differentially Spliced Genes as Markers of Sex for Forensic Entomology,,

Blow flies (Calliphoridae) are important medically and economically and are commonly used in forensics as temporal markers in death investigations. While phenotypic traits in adult flies can be sexually dimorphic, sex identification in immatures is difficult. Consequently, little is known about how sex may result in developmental disparities among sexes even though there are indications that they may be important in some instances. Since genetic mechanisms for sex are well studied in model flies and species of agricultural and medical importance, we exploit the sex-specifically spliced genes transformer (tra) and doublesex (dsx) in the sex determination pathway to optimize a sex identification assay for immatures. Using known primer sets for tra and with a novel one for dsx, we develop PCR assays for identifying sex in four forensically relevant Calliphoridae species: Lucilia sericata (Meigen), Lucilia cuprina (Wiedemann), Cochliomyia macellaria (Fabricius), and Chrysomya rufifacies (Macquart) and evaluated their performance. Band detection rates were found to range from 71 to 100%, call rates ranged from 90 to 100%, and no error was found when bands could be called. Such information is informative for purposes of testimony and in preparation for development studies. The developed assays will assist in further differentiating sexually dimorphic differences in development of the Calliphoridae and aid in more accurately estimating insect age when age predictive markers (size, development time, molecular expression) are sexually dimorphic.     

Red Lines and Compromises: Mapping Underlying Complexities of Brexit Preferences

The political discourse is characterised by two opposing ideals of hard and soft Brexit. In this article, we present evidence of attitudinal types that map neatly onto these archetypal views. The hard Brexit view is defined by issues that eurosceptics prioritise, most prominently sovereignty. By contrast, europhiles prioritise cooperation with Europe in terms of scientific collaboration and market access. However, attitudinal types are not either/or in the minds of the British public, and many prioritise all or none of the issues. Further, the two opposing positions together account for 37 per cent of the public's view. That is, just over one‐third differentiate between the salient issues in ways congruent with political ideals. National identity plays a particular role in the sociodemographic profiles of these attitude types. Older people have a strong stance in any direction (sovereignty, cooperation, or both), but national identity is linked to differentiated positions (sovereignty only or cooperation only).
