Testing Discriminant Functions for Sex Determination from Deciduous Teeth*,†

Abstract: Three studies have proposed discriminant functions for sex determination from deciduous tooth crown dimensions, and this study tests the existing functions on a sample of 46 Portuguese immature skeletons of known sex, aged from birth to 10 years. Deciduous teeth were measured in their mesiodistal and faciolingual crown dimensions, and percentage of correct allocation accuracy in determining sex using each specific function was determined. Discriminant functions were also calculated from data collected for this study and tested using cross‐validation. Results show poor overall accuracy (33.3–75%) and poor cross‐validation (46.2–60.0%). This is related to low sexual dimorphism in deciduous tooth crown size, as well as differences in degree of sexual dimorphism and in overall tooth size between different samples. For these reasons, deciduous crown size does not seem to show significant forensic value as discriminator of sex, particularly when methods developed on one population are applied to individuals of another population.     

Parallel Proceedings in Investor‐State Treaty Arbitration: Responses for Treaty‐Drafters,Arbitrators and Parties

Parallel investment treaty arbitrations present a demonstrated risk of inconsistent awards. This article examines several ameliorative responses to parallel investment treaty proceedings, executable by treaty‐drafters, arbitrators and parties themselves. The unique jurisdiction mechanics and applicable law in investment treaty disputes frames the responses available. Despite the unique context within which parallel investment arbitrations occur, the challenges they pose to party interests, to principles including legal fairness and to the effective pursuit of dispute resolution closely resemble those posed by parallel proceedings in other domestic and international legal fora.     

The ‘relics of Joan of Arc’: A forensic multidisciplinary analysis

Archaeological remains can provide concrete cases, making it possible to develop, refine or validate medico-legal techniques.In the case of the so-called ‘Joan of Arc's relics’ (a group of bone and archaeological remains known as the ‘Bottle of Chinon’), 14 specialists analysed the samples such as a cadaver X of carbonised aspect: forensic anthropologist, medical examiners, pathologists, geneticists, radiologist, biochemists, palynologists, zoologist and archaeologist. Materials, methods and results of this study are presented here.This study aims to offer an exploitable methodology for the modern medico-legal cases of small quantities of human bones of carbonised aspect.     

Secondary Traumatic Stress and Burnout among Law Enforcement Investigators Exposed to Disturbing Media Images

This study examines the psychological impact of viewing disturbing media on investigators engaged in computer forensics work. Twenty-eight federal law enforcement personnel who investigate Internet child pornography cases completed measures of secondary traumatic stress disorder (STSD) and burnout. Substantial percentages of investigators reported poor psychological well-being. Greater exposure to disturbing media was related to higher levels of STSD and cynicism. STSD and burnout scores were related to increased protectiveness of family, reliance on co-workers, general distrust, and turnover intentions. On a positive note, investigators scored high in professional efficacy, indicating they feel their work makes a difference. Furthermore, personnel with supportive relationships scored lower on both STSD and burnout.     

Now <Emphasis Type="Italic">Everyone</Emphasis> Looks the Same: Alcohol Intoxication Reduces the Own-Race Bias in Face Recognition

Several factors influence the reliability of eyewitness identification evidence. Typically, recognition for same-race faces is better than for different-race faces (the own-race bias), and alcohol intoxication decreases overall face recognition accuracy. This research investigated how alcohol intoxication influences the own-race bias. Asian and European participants completed tests of recognition memory for Asian and European faces when either mildly intoxicated (mean breath alcohol concentration of .05) or when sober. Compared to their sober counterparts, intoxicated participants showed a reduced own-race bias. Specifically, alcohol intoxication had a larger negative effect on the recognition of same-race faces compared to different-race faces. The legal and theoretical implications of these results are discussed.     

Dangerous and severe personality disorder: An investigation of the construct

Introduction of the construct “Dangerous and Severe Personality Disorder” (DSPD) by the UK Home Office and Department of Health has provoked strong debate and opposition. Its aims and that of proposed subsequent legislation was to enhance public protection by identifying and detaining a minority of persons with severe personality disorder who pose a high risk of serious sexual/violent offending. The most serious criticism was the ethical implication of allowing indefinite detention of people without criminal convictions. More recently, policy emphasis has shifted towards treatment. 1396 male prisoners serving sentences of 2+ years for sexual/violent offenses were prospectively interviewed (personality disorders, psychopathy, and risk) at a mean follow-up of 2 years. The prevalence of DSPD was 15%. Significantly more re-offended. Five DSPD offenders would need treatment to prevent one violent act. Based on an estimate of attributable risk, successful treatment of DSPD could reduce violent re-convictions among DSPD offenders by 71% and violent/sexual re-offenses in the prison population by 27%. DSPD criteria correctly identify high risk prisoners but primarily through risk-related demographic features. DSPD does not accurately identify serious sexual/violent re-offenders. The DSPD programme may reduce major violent re-offending if treatment interventions prove effective.     

LIFE AFTER DEATH: THE NEED TO ADDRESS THE LEGAL STATUS OF POSTHUMOUSLY CONCEIVED CHILDREN

The advance of reproductive technology, coupled with a legal system that cannot keep up, has had a detrimental effect on posthumously conceived children. There is controversy over whether a child conceived after the death of one parent, by way of reproductive technology, is considered a child of that parent for inheritance purposes. An overwhelming majority of state legislatures have not given consideration to the unique question that posthumously conceived children pose. Legislative inaction has forced state courts to apply antiquated laws in the midst of a technological revolution. The result: children are being denied inheritance rights to their deceased parent's estate solely because of the way they were conceived. This Note advocates that all children should be given the same rights and benefits regardless of how they are conceived. To accomplish that goal, this Note proposes a model state statute to be adopted in all states. The model statute deems a posthumously conceived child to be the child of his or her deceased parent, and thus entitled to inheritance rights, if 1) the posthumously conceived child was provided for by will, or 2) the deceased parent intended to be a parent; there is a genetic relationship between parent and child; the child is born within three years from the death of his or her deceased parent; and the child's best interest, balanced against the state's interests, exceeds the state's interest. The desired effect of the statute is to put posthumously conceived children on equal footing with naturally conceived children.
