Lawfulness of a randomised trial of the new community treatment order regime for England and Wales

This article debates and defends the lawfulness of a randomised controlled trial of compulsory outpatient treatment under the mental health legislation for England and Wales. The trial is designed to compare the outcomes for patients of their treatment under the new Community Treatment Order (CTO) regime with their treatment under the older leave scheme - the two main forms of compulsory care in the community now authorised by the revised Mental Health Act 1983. The methods for the trial involve the random allocation of some patients between the two schemes, when they are considered by their Responsible Clinicians to be eligible for some form of compulsory outpatient care. The main question we consider is the lawfulness of that aspect of the methods. Can a carefully selected group of patients be allocated at random between the two regimes to permit an evaluation to proceed? Or would that involve some departure from the decision-making criteria specified by law? We argue that a group of patients can be identified who meet - simultaneously - the tests for treatment under both the CTO and the leave schemes. Those patients could then be allocated lawfully to treatment under either scheme. This opens the door, we argue, to their random allocation between the two schemes for the purposes of the research. In reaching this conclusion, we explain the methods and aims of the trial and closely compare the respective features of the leave and CTO regimes.     

Evaluation of a Freezer Mill for Bone Pulverization prior to DNA Extraction: An Improved Workflow for STR Analysis

Traditional methods for bone pulverization typically generate heat, risking stability of DNA sample. SPEX? has developed cryogenic grinders which introduce liquid nitrogen to cool the sample and aid in the grinding process. In this study, the Freezer Mill 6970 EFM was used with two DNA extraction methods and routine downstream STR analysis procedures. DNA from as little as 0.1 g of bone powder was used to develop full STR profiles after freezer mill pulverization, and the method was reproducible. Further, no contamination was detected upon cleaning/reuse of the sample vials. There were no significant differences in DNA yield, STR alleles detected, or peak heights using the freezer mill as compared to traditional grinding, and successful DNA profiles were achieved from as low as 0.1 g of bone powder with this method. Overall, this work indicates that this cryogenic mill method may be used as a viable alternative to traditional tissue grinders.     

Female-perpetrated sexual abuse: a review of victim and professional perspectives

Abstract

Professional attitudes towards female-perpetrated sexual abuse (FPSA) reportedly reflect the gender-role expectations found in broader society, which cast males almost exclusively as sexual aggressors or willing sexual recipients, females as sexually non-coercive or victims and male-perpetrated sexual abuse as particularly significant or injurious. Such views, however, appear to stand in contrast to the perspectives of individuals who have experienced FPSA. This paper details a systematic review of peer-reviewed quantitative and qualitative literature examining these different (professional and victim) perspectives. Although the methodological shortcomings of primary papers limit the conclusions that can be drawn, the findings suggest that victim and professional perspectives of FPSA remain discrepant; professionals generally considered FPSA as less serious, less harmful and less deserving of investigation than male-perpetrated abuse; while victims of FPSA felt their experiences influenced significantly their psychological wellbeing and abilities to form and maintain interpersonal relationships. These findings are discussed in relation to professional practice and suggestions for future research.     

A Comparison of Enhancement Techniques for Footwear Impressions on Dark and Patterned Fabrics,

The use of chemical enhancement techniques on porous substrates, such as fabrics, poses several challenges predominantly due to the occurrence of background staining and diffusion as well as visualization difficulties. A range of readily available chemical and lighting techniques were utilized to enhance footwear impressions made in blood, soil, and urine on dark and patterned fabrics. Footwear impressions were all prepared at a set force using a specifically built footwear rig. In most cases, results demonstrated that fluorescent chemical techniques were required for visualization as nonfluorescent techniques provided little or no contrast with the background. Occasionally, this contrast was improved by oblique lighting. Successful results were obtained for the enhancement of footwear impressions in blood; however, the enhancement of footwear impressions in urine and soil on dark and patterned fabrics was much more limited. The results demonstrate that visualization and fluorescent enhancement on porous substrates such as fabrics is possible.     

The ethnic and non-ethnic politics of everyday life in Bulgaria's southern borderland

Ethnicity is found in real-world contexts where non-ethnic forms of identification are available. This conclusion is drawn from an empirical study carried out in the multiethnic town of Kurdzhali in Southern Bulgaria, where members of the Bulgarian majority live alongside the Turkish minority. Drawing on the “everyday nationhood” agenda that aims to provide a methodological toolkit for the study of ethnicity/nationhood without overpredicting its importance, the study involved the collection of survey, interview, and ethnographic data. Against the expectations of some experienced scholars of the Central and Eastern Europe region, ethnic identity was found to be more salient for the majority Bulgarians than for the minority Turks. However, the ethnographic data revealed the importance of a rural–urban cleavage that was not predicted by the research design. On the basis of this finding, I argue that the “everyday nationhood” approach could be improved by including a complementary focus on non-ethnic attachments that have been emphasized by scholarship or journalism relevant to the given context. Rather than assuming the centrality of ethnicity, such an “everyday identifications” approach would start from the assumption that ethnic narratives of identity always have to compete with non-ethnic ones.     

Drug testing in the public sector: The role of unions

Not surprisingly, unions have traditionally played an active role in employee drug testing. And, although the U.S. Supreme Court upheld the constitutionality of drug testing in two 1989 decisions, unions have continued to wage challenges to urinalysis under the U.S. Constitution and in the labor arena. As this research shows, federal as well as state and local government unions have had some success in challenging the categories of employees targeted for testing, good faith bargaining over drug testing, and due process and equity violations around testing.     

microRNA Detection in Blood,Urine, Semen,and Saliva Stains After Compromising Treatments

Evaluation of microRNA (miRNA) expression as a potential method for forensic body fluid identification has been the subject of investigation over the past several years. Because of their size and encapsulation within proteins and lipids, miRNAs are inherently less susceptible to degradation than other RNAs. In this work, blood, urine, semen, and saliva were exposed to environmental and chemical conditions mimicking sample compromise at the crime scene. For many treated samples, including 100% of blood samples, miRNAs remained detectable, comparable to the untreated control. Sample degradation varied by body fluid and treatment, with blood remarkably resistant, while semen and saliva are more susceptible to environmental insult. Body fluid identification using relative miRNA expression of blood and semen of the exposed samples was 100% and 94%, respectively. Given the overall robust results herein, the case is strengthened for the use of miRNAs as a molecular method for body fluid identification.
