Variability of simulants used in recreating stab events

Formic acid (FA) concentration was measured in post-mortem blood and urine samples as methyl formate using a headspace in-tube extraction gas-chromatography-mass-spectrometry method. A total of 113 cases were analyzed, each including a blood and urine sample fortified with 1% sodium fluoride. The cases were divided into three groups: regular (n=59), putrefied (n=30), and methanol-positive (n=22) cases. There was no evidence of ante-mortem methanol consumption in the regular and putrefied cases. In regular cases, the mean (and median) FA concentrations were 0.04 g/l (0.04 g/l) and 0.06 g/l (0.04 g/l) in blood and urine, respectively. In putrefied cases, the mean (and median) FA concentrations were substantially higher, 0.24 g/l (0.22 g/l) and 0.25 g/l (0.15 g/l) in blood and urine, respectively. In three putrefied cases, FA concentration in blood exceeded 0.5 g/l, a level associated with fatal methanol poisoning. Ten putrefied cases were reanalyzed after 3-4 months storage, and no significant changes in FA concentrations were seen. These observations suggest that FA was formed by putrefaction during the post-mortem period, not during sample storage when sodium fluoride was added as a preservative. In methanol-positive cases, the mean (and median) FA concentrations were 0.80 g/l (0.88 g/l) and 3.4 g/l (3.3 g/l) in blood and urine, respectively, and the concentrations ranged from 0.19 to 1.0 g/l in blood and from 1.7 to 5.6 g/l in urine. The mean (and median) methanol concentrations in methanol-positive cases were 3.0 g/l (3.0 g/l) and 4.4 g/l (4.7 g/l) in blood and in urine, respectively. The highest methanol concentrations were 6.0 g/l and 8.7 g/l in blood and urine, respectively. No ethyl alcohol was found in the methanol-positive blood samples. Poor correlation was shown between blood and urine concentrations of FA. Poor correlations were also shown, in both blood and urine, between methanol and FA concentrations.     

Violence during Pregnancy: Investigating Infanticidal Motives

This study aimed to investigate whether potentially infanticidal violence by men toward their pregnant partners’ is motivated by jealousy, and hence paternity uncertainty. It was predicted that men who used potentially infanticidal violence (directing their physical aggression towards their pregnant partners’ abdominal region) would have younger partners as this is associated with greater reproductive value; would be in relationships of shorter duration as this may indicate less stable relationships; and would be more jealous and restrictive of their partner’s movements and friendships than violent men who directed their aggression to other regions of their pregnant partners’ body. Relationship behaviors were provided from 43 women in domestic violence shelters (n?=?43), using measures of the following: (1) partner physical aggression (2) victim fear and injury, (3) areas of bodily assault (when pregnant and when not pregnant), (4) controlling behaviors, and (5) topics of disagreement. Violence directed towards the fetus was associated with shorter relationships where both partners were younger. In such relationships, there was more physical aggression from the male partner, he used more controlling behaviors to isolate his partner, and the partners had more disagreements arising from his jealousy, compared with when physical aggression was not directed towards the fetus. These findings are consistent with an infanticidal motive for men’s aggression directed towards their pregnant partners. If paternity uncertainty is a primary cause of this dangerous form of domestic violence, it should form an important element in any screening instrument.     

The age of risk: risk perception and determination following the Mental Health Act 2007

Reforms to the mental health law framework for England and Wales, which were introduced by the Mental Health Act 2007, are now having a practical effect on day-to-day mental health decision-making. The 2007 Act amends the Mental Health Act 1983, which governs the compulsory hospitalisation and treatment of people with mental disorder; and represents the culmination of a protracted and controversial reform process which has spanned much of the last 15 years. One of the key foci in the 2007 Act is the question of the risk posed by the patient, primarily to others; a result of both the social and political impetus behind the reform process and mounting public anxiety at the management of the mentally disordered. The new Act seeks, as with past legislation, to find the elusive balance between protecting and facilitating the individual's autonomy while also providing an effective framework for the wider public right to protection. The 2007 Act solidifies the dominance of risk by providing a legitimating framework in which risk can be assessed, monitored, and managed. This attitudinal change is demonstrated by the gradual and almost insidious adoption of risk terminology within the practical decision-making setting and the increasing use of risk assessment and management tools. This article is informed by an empirical study which examined individual professional and institutional responses to the mental health legislation in relation to risk. It examines whether the amended legislative framework amplifies risk as an increasingly dominant concern within decision-making. The paper then goes on to consider how decision-makers use risk to assist with their daily roles. Extrapolated from data obtained through the study, several models of risk determination are then discussed. Finally, some thought is given to whether the extension of the risk concept has the potential to become more fundamental within the organisation and legitimisation of mental health care.     

Deaths While under Probation Supervision: What Role for Human Rights Legislation?

Article 3 of the Universal Declaration of Human Rights (UDHR) states that ‘everyone has the right to life’. This right is contained in all human rights treaties that developed from the UDHR, including the European Convention on Human Rights (ECHR). Yet, as we argue, the UK government is failing to protect this right when it comes to certain groups of people under probation supervision. To date, human rights legislation has failed adequately to protect these vulnerable individuals and to hold the state to account. This article explores the greater potential for using human rights legislation to ensure better accountability in this area.     

Social climate within an adolescent medium-secure facility

The objectives of the study were to investigate the social climate of two different types of units (open vs. secure) contained within the same South London adolescent medium-secure facility. Two hypotheses were generated: (a) adolescents would rate the social climate of the whole facility in a more negative direction than staff and (b) adolescents and staff would rate the social climate of the open units in a more positive direction than the social climate of the secure units. 43 adolescents and 49 staff members from the open units and the secure units were recruited and completed the Correctional Institutions Environment Scale (CIES), a measure of social climate. Overall, adolescents tended to rate the facility in a more negative direction. All participants rated the open units in a more positive direction than secure units. However, on selected subscales there were differences. The findings of this study suggest that adolescents and staff may perceive their shared social climate differently. This may have implications for those attempting to develop positive social climates within secure services.     

Possible applications of Y chromosome STRs in examination of abortion tissue

By application of Y-chromosomal STRs, DNA analysis of abortion material can be considerably facilitated since great excess of maternal DNA is tolerated without disturbing the Y-STR amplification. If paternity can't be excluded on the basis of the Y-STR haplotype, further examinations must follow, e.g. autosomal STR analysis. For this purpose, histological preparation of the abortion tissue might still be necessary. Different Y-chromosomal haplotypes of embryo and putative father usually lead to an exclusion from paternity. Based on four case examples, the feasibility of this method is discussed.
