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.     

Legislators and Administrators: Complex Relationships Complicated by Term Limits

State legislators' relationships with administrators have received scant attention in the literature despite the importance of these relationships for delivery of public services. We explored whether or not the legislator‐administrator relationship in one professional state legislature resembles Congress's oversight of federal agencies. We also assessed whether or not term limits changed this relationship. Our findings indicate that monitoring state agencies was a low priority for this legislature, and it dropped even lower after term limits were implemented. More specifically, we found some institutional roles to be associated with legislators placing a higher priority on monitoring, especially before term limits, whereas some individual motives were associated with a lower priority, especially after term limits. Legislators exhibited more confusion about the process of monitoring after term limits.     

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.     

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.     

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.     

Exploring gender differences in dating violence/harassment prevention programming in middle schools: results from a randomized experiment

In this study, we randomly assigned 123 sixth and seventh grade classrooms from seven middle schools in the greater Cleveland area to one of two five-session curricula addressing gender violence/sexual harassment (GV/SH) or to a no-treatment control group. A baseline survey and two follow-up surveys were administered immediately after the treatment (Wave 2) and about six months post-treatment (Wave 3). In an earlier paper, we demonstrated the effectiveness of two approaches to youth GV/SH prevention programming (a fact-based, law and justice curriculum and an interaction-based curriculum). In this paper, we explored whether these largely positive findings remain for both girls and boys, including whether girls experience higher levels of GV/SH than boys. Most of our statistical models proved to be non-statistically significant. However, in 2 of our 48 victimization/perpetration (any violence, sexual violence and non-sexual violence) models (across two post-intervention follow-up points), we observed that the interventions reduced peer (male or female, non-dating partner) sexual violence victimization and reduced peer perpetration, but another outcome model indicated that the interventions increased dating perpetration. These mixed findings will need to be explored further in future research. Regarding our primary research question, we observed no statistically significant differences for the treatment multiplied by gender interaction terms for any of the perpetration or victimization outcome models, suggesting that the treatment had similar effects on girls and boys. However, we did observe that boys are more involved in violence than girls: both as victims and perpetrators. Boys experienced significantly more of three types of victimization from peers and dating partners compared to what girls experienced at the hands of their peers and dating partners. As perpetrators, boys committed more sexual victimization against peers (immediately post-intervention only) and more sexual victimization against dating partners than girls. The implications of these results are discussed.
