The intersection of genes and neuropsychological deficits in the prediction of adolescent delinquency and low self-control

Gottfredson and Hirschi's A General Theory of Crime, Moffitt's developmental taxonomy theory, and Caspi et al.'s Gene x Environment study are three of the most influential pieces of contemporary criminological scholarship. Even so, there has been little attempt to integrate and empirically assess these three perspectives simultaneously. This article addresses this gap in the literature by analyzing phenotypic and genotypic data from the National Longitudinal Study of Adolescent Health (Add Health). The results revealed that all three perspectives have considerable empirical support, where neuropsychological deficits interact with the MAOA genotype to predict adolescent delinquency and levels of self-control for White males. The theoretical implications of the findings are noted.     

Convergence or path dependency in policies to foster the creation of university spin-off firms? A comparison of France and the United Kingdom

This paper examines attempts by French and UK governments to fill the gap between the US and Europe with respect to the creation of academic spin-offs. Analysis of the contrasting cases of the UK and France, shows that there is no convergence of national policies to foster the creation of firms by academics. Rather, the two countries demonstrate different rationales and approaches to policy in this area. In UK, the rationale for spin-off policy is mainly to develop a third stream of financing. Spin-offs are a part of a policy to commercialize technology and knowledge created by universities. Policy is at the university level, leading to the creation of diverse structures. Public schemes bring public money directly to universities. In France, the rationale for policy towards the creation of new ventures by academics is the development of high technology new ventures as part of a technological entrepreneurship policy. The notion of a third stream of financing for universities is an argument that is never advanced. The UK has placed the universities at the heart of policies aimed at the creation of spin-offs, this is not the case in France.

Can Cephalometrics Discriminate Between the Sexes in a Diverse Juvenile Sample?

A critical component of the biological profile is sex estimation. Methods commonly used for sex estimation in adults do not work well for juveniles. Population‐specific studies have used cephalometrics to estimate juvenile sex with 80–90% accuracy. Our study attempts to estimate sex in individuals less than 18 years of age using a sample of 1618 lateral cephalograms incorporating all three Angle Class occlusions as well as population diversity. For the sample as a whole, 10 skeletal cephalometrics were found to have significant differences between the sexes. Males and females classify correctly about 50% of the time. Dividing the sample by age groups and race/ethnicity improves results for older age groups and Native Americans, Hispanics, and Asian Americans. Our results indicate that cephalometrics are not useful in determining sex of unidentified juveniles when age and race are not known.     

A validation study for duct tape end matches

Fracture matches are considered to be the strongest association achievable in forensic examinations of glass, metal, wood, plastic, paint, tape, and other trace evidence. Despite being fairly routine examinations, few publications exist to support their admissibility in court. This study was designed, using duct tape as the fractured medium, to determine the validity and error rate associated with conducting end match (fracture match) examinations on this material. Five test designs, which varied either the source roll of tape or manner of separation (torn or cut) from the roll, were administered to four analysts with instructions to examine the assigned test sets for end matches. If an end match was not identified by the initial analyst, the entire test set was independently evaluated by the remaining three analysts. Results indicated that while tape grade did not hinder end match identification, the manner of separation could affect results.
