Does Mirror Imaging a Radiograph Affect Reliability of Age Assessment Using the Greulich and Pyle Atlas?*

Abstract: Age estimation is routinely undertaken by comparing radiographs of the individual in question to published reference samples of individuals of known age. This study examines the reliability of age estimation utilizing the Greulich and Pyle atlas in relation to both left‐ and right‐hand/wrist radiographs and explores whether reversing right‐hand/wrist radiographs, so that they are in the same anatomical orientation as those images used in the atlas affects reliability. A total of 403 left‐hand/wrist radiographs and 415 right‐hand/wrist radiographs were age assessed using the Greulich and Pyle atlas. Analysis showed that there is no significant loss in reliability when radiographs of the right hand (women R² = 0.887 and men R² = 0.907) are utilized instead of the left (women R² = 0.939 and men R² = 0.940) or when they are assessed as mirror images to those printed in the reference atlas (reversed female left hand R² = 0.929 and reversed male left hand R² = 0.931).     

The characterisation of two halogenated cathinone analogues: 3,5-difluoromethcathinone and 3,5-dichloromethcathinone

Australia has seen an increase in the importation and use of drugs that are marketed and sold as "Legal Highs". These compounds have largely tended to be various cathinone analogues, with 4-methylmethcathinone the most prominent to date. In January 2009, unknown samples were submitted for analysis along with a large seizure of 3-fluoromethcathinone as part of a police operation. The samples were analysed and determined to be 3,5-difluoromethcathinone and 3,5-dichloromethcathinone. These compounds were synthesised and characterised. The GC-MS data of the samples and their N-acetyl derivatives, NMR, vapour-phase and condensed-phase IR for these previously unreported compounds are presented. This analytical data will enable laboratories to confirm the presence of these compounds in the absence of commercially available reference standards.     

A Cross-cultural Validation of the Brief Child Abuse Potential Inventory (BCAP)

The aim of this study was to provide preliminary findings on the cross-cultural validation and reliability of the Brief Child Abuse Potential Inventory (BCAP) developed by Ondersma et al. (Journal of Clinical Child and Adolescent Psychology, 2005). A community sample of 324 parents was recruited through schools from a range of socioeconomic areas in a large UK city. The BCAP appears to be a reliable instrument that is easy to use and shows promise as a brief screening tool for parental child abuse potential within the UK. Modifications are suggested to the validity scales and the conceptual structure based on this sample, however, detailed testing of the utility of this scale for clinical practice outside the US should be pursued.     

An Examination of the Influence of Strength of Evidence Variables in the Prosecution’s Decision to Dismiss Driving While Intoxicated Cases

The majority of research examining prosecutorial discretion has focused on legal factors such as the seriousness of the offense or the extra-legal characteristics of the accused including race/ethnicity and gender. The amount of variance explained by court researchers, however, remains quite low. The present study extends previous research examining the primary determinants of prosecutor??s decision to dismiss or fully prosecute focusing on driving while intoxicated cases. We focus on the predictive contribution of the strength of evidence relative to legal and extra-legal variables. The data consist of 2,358 driving while intoxicated cases filed in Harris County, Texas during the first 8?months of 1999. The findings strongly support the inclusion of strength of evidence variables in court research and further suggest their past omission may have attributed significance to spurious relationships.     

Judicial use of social science research

American courts use social science research in three distinct ways: to make law, to determine facts, and to provide context. In this article, we review and critique the approaches that courts have traditionally taken to dealing with each form of social research. We also summarize and integrate a body of work offering a different perspective that treats law-making research associal authority, fact-finding research associal fact, and context-providing research associal framework. We end by proposing a coherent sequence of steps that courts should take when confronted with an empirical question about human behavior.This article was prepared under the auspices of the Task Force on Judicial and Regulatory Decisionmaking of the Carnegie Commission on Science, Technology, and Government. The views expressed are those of the authors rather than of the Task Force or the Commission. We are grateful to David Z. Beckler, Associate Director, for his comments.

Trends in City Conditions During the 1970s: A Survey of Demographic and Socioeconomic Changes

Changes in the demographic and socioeconomic conditions of 627cities between 1970 and 1980 are examined using simple comparisonof means and correlational analytic techniques. Cities are groupedaccording to their type (Central city; suburb), regional location,and rate of population growth (decline). Major changes occurredin employment patterns, income levels, economic bases, racialcomposition, and social pathologies (crime rates)—allmeasures of urban stress. These conditions tended to clusterin certain types of cities: large, declining central citiesof the Northeast and Midwest. But population decline and regionallocation were not found to be independent determinants of urbandistress. National and regional economic trends, especiallychanges in the vitality of the metropolitan area in which acity is located. were the primary determinants.     

Citizen-driven reform of local-level basic services: Community-Based Performance Monitoring

Amid growing interest in forms of participatory and decentralised governance, increasing efforts are being made to increase the accountability, responsiveness, and relevance of the state through active citizenship. Drawing on the theoretical basis for social accountability, this article explores bottom–up views of active citizenship which highlight the importance of the intrinsic as well as the instrumental value of participatory social accountability, and thus of active citizenship. One approach to social accountability, Community-Based Performance Monitoring (CBPM), is used to demonstrate these instrumental and intrinsic values in practice, in relation to local public-service delivery.
