Ethanol stability in unpreserved refrigerated antemortem blood

Ethanol stability in preserved antemortem blood has been widely studied since it is a common practice in cases involving suspected impaired driving to collect antemortem blood in evacuated blood tubes containing sodium fluoride. In some situations, antemortem blood is submitted to a forensic laboratory for ethanol analysis in evacuated blood tubes that contain only an anticoagulant. There has been limited research on ethanol stability in antemortem blood stored without a preservative. On two occasions, antemortem blood was collected from five ethanol-free individuals into 6-ml Vacutainer® tubes containing only 10.8 mg potassium EDTA. The blood tubes were spiked with ethanol to approximately either 0.08 or 0.15 g/dl. Dual-FID headspace gas chromatography was used to analyze 58 blood tubes, 29 from each session, for ethanol 1 day after sample collection and again after 1 year of refrigerated storage (~4°C). Statistically significant decreases in ethanol were detected at the 0.05 level of significance. Mean decreases in ethanol after 1 year of storage for the 0.08 and 0.15 g/dl samples were 0.013 and 0.010 g/dl, respectively. The mean ethanol decrease across all tubes was 0.012 g/dl. The range of decreases for the 58 blood tubes was 0.003–0.018 g/dl. The mean ethanol decreases measured in this unpreserved antemortem blood are comparable in magnitude to those previously observed in antemortem blood containing sodium fluoride after 1 year of refrigerated storage. Ethanol did not increase in the antemortem blood samples despite the absence of sodium fluoride.     

Droplet-based optical trapping for cell separation in mock forensic samples

Optical tweezers have a wide range of uses for mechanical manipulation of objects in the microscopic range. This includes both living and static cells in a variety of biomedical and research applications. Single-focus optical tweezers, formed by focusing a laser beam through a high numerical aperture immersion objective, create a significant force, which enables controlled transport of a variety of different cell types and morphologies in three dimensions. Optical tweezers have been previously reported to capture and separate spermatozoa from a reconstituted simulated postcoital sample. We report herein the development of a simplified, more efficient cell transfer protocol that can separate and isolate both spermatozoa as well as leukocytes, with similar efficiencies as those previously reported. The new cell transfer method was used to separate sperm cells from a reconstituted mixture of spermatozoa and vaginal epithelial cells, with complete STR profiles developed from 50 cells with little evidence of contribution from the female contributor to the mixture. This modified protocol was then used to separate 21 samples of enriched leukocytes, with trapped cells ranging from 5 to 22 cells. Complete STR profiles were developed from as few as 10 leukocytes. Thus, with minimal sample preparation and a short trapping time, this method has the potential to provide an alternative to traditional differential extraction methods for separation of sperm:nonsperm mixtures while also providing versatility for separation of cells with differing morphologies.     

“The savage reduction of the flesh”:1 violence,gender and bodily weaponisation in the 1981 Irish Republican hunger strike protest

This article examines the relationship between performativity, the body and violent identity politics in HMP Maze from 1976 to 1981. In it, I outline a theory of ethnic violence that highlights the exposure of the body to abjection, focusing specifically on the violence against the bodies of Irish Republican hunger strikers during the protest of 1981. I pursue two lines of argument. First, that self-starvation was a means by which the hunger strikers could turn their bodies into weapons, rather than serving as the site of a passive or non-violent protest. Second, while the sexualised abuse of prisoners sought to feminise them, I conclude that the Hunger Strike Protest not only weaponised the bodies of the strikers, but also re-constituted them as masculine.     

Identifying Urban Flashpoints: A Delphi-Derived Model for Scoring Cities’ Vulnerability to Large-Scale Unrest

Although great strides have been made toward forecasting state-level instability, little progress has been made toward the prediction of outbreaks of urban unrest. This article presents a method for the assessment of cities’ vulnerability to large-scale urban unrest. Forty-five factors correlated with urban unrest are identified and weighted by an expert panel. Based on expert elicitation through an iterative Delphi exercise, the explicitly methodological discussion describes both the process and the resulting assessment framework. Results include a tool that will allow users to rank cities on their vulnerability to large-scale urban unrest.     

The emotional intelligence of adult sex offenders: ability based EI assessment

Abstract

Previous research has suggested that sex offenders are deficient in several areas of emotional functioning such as empathy, emotional perception, emotional management and interpersonal functioning. It is unclear, however, whether sex offenders display a general deficit in emotional functioning or whether their emotional deficits are specific to the circumstances in which offences occur. The present study aimed to provide a broad assessment of the emotional functioning of sex offenders by assessing their emotional intelligence (EI) using an abilities-based emotional intelligence test. Nineteen sex offenders, 18 non-sex offending prisoners and 19 controls were administered the Perception, Assimilation and Management branch subtests from the Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT). The results indicated that the sex offenders were not significantly different than the control group, as assessed by these three branches of the MSCEIT. The results lend support to the suggestion that the emotional deficits displayed by sex offenders may be offence-specific. Implications for the use of the MSCEIT in sex offending populations and the role of EI in relapse prevention programmes are discussed.     

Chinese technology transfer policy: the case of the national independent innovation demonstration zone of East Lake

In particular, these technology transfer policies focus on increasing the innovative activity in central China, in order to spur economic development and growth.     

VHA Primary Care Providers’ Perspectives on Screening Female Veterans for Intimate Partner Violence: A Preliminary Assessment

Female Veterans experience intimate partner violence (IPV) at alarming rates. The Veterans Health Administration (VHA) requires foundational research to guide the development of policy and programs to detect IPV among women Veterans and provide interventions. This pilot study reports findings from in-depth qualitative interviews conducted with 12 VHA primary care providers treating female Veterans in the New England region. Although most providers indicated that they were not currently routinely screening for IPV, they expressed positive attitudes and beliefs about screening in VHA primary care settings. Themes also included the importance of a comprehensive health care response to IPV, such as interdisciplinary coordination of care and team-based approaches to detection and intervention. Barriers to routine screening were identified, as well as recommendations for training programs and clinical tools to inform the successful implementation of a standardized IPV screening and response program in VHA. Although preliminary, these findings represent an initial step in an essential line of research.     

An exploratory study of women prisoners’ attitudes towards their self-harm and the use of medical skin camouflage

Self-harm is a growing problem in UK prisons with women self-harming more than men. Self-harm can leave permanent scarring. Research on scarring suggests that living with scars can lead to psychological difficulties; however, there is little research on the specific effects of self-harm scars. Medical skin camouflage (MSC) can be used to cover numerous skin conditions. The use of MSC for women in prison with self-harm scars has not been examined previously. A focus group involving 10 women prisoners aimed to (1) explore feelings about self-harm scars, (2) examine effects that scars have on life in prison and (3) examine thoughts on using MSC in prison. This group formed part of a larger project designed to test the feasibility and acceptability of MSC for women who self-harm in prison. A topic guide was created with two service user researchers with experience of self-harm in prison. The results have been divided into three themes: (1) feelings about self-harm scars, (2) covering self-harm scars and (3) attitudes towards MSC. Our findings indicate that women in prison tend to feel embarrassed and self-conscious about their scars, and the presence of scars affects their relationships within prison. The women were enthusiastic about MSC, suggesting that it has the potential to affect women’s well-being and ability to engage with others.
