A Method for Estimating Sex Using Metric Analysis of the Scapula*

Abstract: The most accurate and precise methods for the assessment of age and stature often require knowledge of sex. Thus, being able to correctly identify sex from skeletal remains is critical in the forensic context. The presence of the os coxae or skull can never be guaranteed, making the development of reliable methods of sex estimation using other skeletal elements necessary. Using a 724 individual calibration sample from the Hamann‐Todd collection, this study identifies sexual dimorphism in the human scapula, and presents a new five‐variable discriminant function for sex estimation. The overall accuracy of this method proved to be 95.7% on the cross‐validated calibration sample, 92.5% on an 80 individual test sample from the Hamann‐Todd collection, and 84.4% on a 32 individual test sample from the skeletal collection of the Wichita State University Biological Anthropology Laboratory. Additionally, a slightly less accurate two‐variable model was developed and has cross‐validated accuracy of 91.3%.     

The Positive Role of School Climate on School Victimization,Depression, and Suicidal Ideation Among School-Attending Homeless Youth

Although homeless youth face a higher risk of victimization and mental health problems, little is known about school victimization and mental health outcomes for school-attending homeless youth. This study examined the relationship between school climate and school-related victimization and mental health problems among homeless youth. Multivariate analyses were conducted to examine the relationship between school climate factors and school victimization, suicidal ideation, and depression tendency in a representative sample of 1,169 school-attending homeless youth in 9th and 11th grades in California. Findings show that school-attending homeless youth are at high risk of being victimized at school and have high rates of depression tendency and suicidal ideation. Positive school climate, especially perceived high expectations from teachers and safety in school, was associated with lower rates of school victimization and mental health problems. The role of supportive school climate in the lives of school-attending homeless youth is discussed and future implications are suggested.     

Using the role-play at the lectern: developing “work-ready” and confident professionals

As Waters notes, the role-play is not traditionally used as a teaching technique in law schools. Educators utilise role-play in many disciplines, including health, business, psychology, economics and literature; yet apart from clinical settings or for teaching practical legal skills, the role-play seems to be underutilised in legal education. An empirical study of 67 law students from the University of Western Australia (UWA) Law School set out to investigate the utility of the role-play as a device for instilling confidence in students and assisting them to prepare for professional practice. Although the classroom and class size were large and teaching took place in a lecture theatre, the role-play worked effectively. Students reported greater knowledge, understanding, confidence and skill with conducting themselves in a professional practice context. The study shows the need to embrace the role-play as an experiential learning technique that can work as effectively in an intensive, large-class setting as it does in smaller or clinical classrooms. The study revealed that the role-play technique worked very well and that the role-play is a versatile and very much “alive” pedagogical technique of value to any law school.     

The Strictness of Strict Liability

This article conceptualizes what strict liability is in the criminal law. Four properties are found to be individually necessary, only jointly sufficient, for there to be the kind of moral blameworthiness that must underlie any just punishment: prima facie wrongdoing, absence of justification, prima facie culpability, and absence of excuse. Whenever criminal liability is imposed without the presence of one or more of these properties, the liabuility is said to be strict.     

Do a Law’s Policy Implications Affect Beliefs About Its Constitutionality? An Experimental Test

Although a substantial empirical literature has found associations between judges' political orientation and their judicial decisions, the nature of the relationship between policy preferences and constitutional reasoning remains unclear. In this experimental study, law students were asked to determine the constitutionality of a hypothetical law, where the policy implications of the law were manipulated while holding all legal evidence constant. The data indicate that, even with an incentive to select the ruling best supported by the legal evidence, liberal participants were more likely to overturn laws that decreased taxes than laws that increased taxes. The opposite pattern held for conservatives. The experimental manipulation significantly affected even those participants who believed their policy preferences had no influence on their constitutional decisions.

Public Choice - Do informed electorates choose better candidates? While that question is straightforward, its answer often is elusive. Typically, candidate-quality information is neither salient...     

Closing Off Opportunities for Crime: An Evaluation of Alley-Gating

A new situational crime prevention measure recently introduced into Great Britain involves the fitting of gates to alleyways running along the back of terraced properties to restrict access to local residents and reduce opportunities for offenders. A number of quantitative techniques were used to assess the success of the intervention in reducing burglary in the City of Liverpool. The results demonstrate that, relative to a suitable comparison area, burglary was reduced by approximately 37%, there was a diffusion of benefit to properties in the surrounding areas, and the scheme was cost beneficial with a saving of £1.86 for every pound spent. The analyses provide persuasive evidence that these reductions were attributable to the intervention. We argue that the methodological techniques demonstrated here can be applied more widely to crime prevention evaluations.     

Determination of cocaine and its metabolites in brain tissue using high-flow solid-phase extraction columns and high-performance liquid chromatography.

A new solid-phase extraction procedure for the determination of cocaine and some of its metabolites in brain tissue, using high-flow co-polymeric sorbents is reported as a substantial improvement on our recently reported procedure. The recovery of cocaine, norcocaine and cocaethylene was excellent as was the reproducibility of the extraction. The use of high-flow sorbents allowed the easy extraction of tissue without the need for a time-consuming lipase digestion, regardless of sample viscosity or physical nature. The use of these solid-phase columns provided many advantages over the more commonly used solvent extraction, including an increase in extraction speed and efficiency, reduced operator time, reduced solvent use and disposal volumes and exceptional extract quality. The procedure was successfully applied to rabbit brains spiked with cocaine, benzoylecgonine, norcocaine and cocaethylene.
