A fresh scientific look at transfer and persistence: From a materials science and tribology perspective

Knowledge of the mechanisms governing transfer, persistence, and recovery of trace evidence, together with background prevalence in the population of interest, and other task relevant information, is key for the forensic interpretation and reconstruction of what happened at the activity level. Up to now, this informational “toolkit” has largely been developed through empirical forensic studies on specific trace materials such as glass, textile fibers, and soil. Combined with the identified systemic siloing between disciplines, while valuable, such research tends to be very material-dependent, introducing specific parameters and interpretations that may have actually impeded the recognition of underlying foundational factors applicable to most material types. In Australia, there has been a renewed interest in developing a discipline-independent framework for the interpretation and/or reconstruction of trace evidence to interpret specific circumstances in casework. In this paper, we present a discipline agnostic “way of thinking” that has been anchored in foundational science underpinning the trace evidence discipline. Physical and mechanical material properties such as material geometry and surface topography, strength, stiffness, and hardness collectively influence contact interactions through underlying friction, wear, and lubrication cause and effect mechanisms. We discuss how these fundamental factors and parameters stemming from materials science and tribology may be adopted and adapted by forensic practitioners and researchers to contribute to a better understanding of transfer, persistence, and recovery mechanisms irrespective of evidence discipline and material type. Examples are provided to demonstrate the practical significance to real-life casework and academic research.     

Staging race: Florence Mills,celebrity, identity and performance in 1920s Britain

This article focuses on the time the African American performer Florence Mills spent in Britain in the 1920s. Mills was one of the most popular performers of the period, taking a lead in African American vaudeville productions, she was admired by working class and ‘elite’ black and white audiences. Our paper examines four examples of Mills’ British fan mail alongside newspaper reports of her performances in London. These reveal complex themes of identity, of Britishness, sexuality, gender and class within the context of changing international understandings of race relations in the Inter-war period. We utilise these letters alongside newspaper reports to consider how Mills’ presence in Britain as a performer and anti-racist activist influenced debates and personal reflections on racial identity, sexual desire and belonging to Britain.     

‘Yeah but,no but’ – Pinnock and Powell in the Supreme Court

This note considers the Supreme Court decisions in Manchester CC v Pinnock and Hounslow LBC v Powell. It is argued that there are a number of remaining outstanding questions around proportionality, including: deference; section 89, Housing Act 1980; procedural issues; ‘publicness’; and the future landscape.     

Facial Soft Tissue Thickness Database for Craniofacial Reconstruction in Korean Adults

Abstract: One hundred Korean adults (50 men, 50 women) were scanned in the upright position using a cone‐beam CT (CBCT) scanner. The soft tissue (ST) thicknesses were measured at 31 landmarks, 10 midline and 21 bilateral landmark sites, and the means and standard deviations were obtained for male and female subjects. While 18 of 31 landmarks showed sex differences, the majority showed higher values for male subjects with the exception of a few landmark sites corresponding to the zygoma area, which showed smaller values in men than in women. The mandibular area showed greater differences between the right and left sides. Overall, the ST thickness measurements obtained in this study can be used as a database for the forensic craniofacial reconstruction of Korean adult faces.     

The trust deficit in Sino-Japanese relations

Abstract

Recent years have seen a deterioration in political relations between China and Japan, in particular over the disputed Senkaku/Diaoyu islands and history-related problems. Commentators have noted an attendant decline in trust between the two sides and have stressed the need for confidence-building measures in order to address the trust deficit. This article explores the origins of declining trust between the Chinese and Japanese leaderships. It argues that attempts to build a friendly and trusting relationship in the early post-war and post-normalisation periods began to fail in the 1980s, and have been in a gradual state of decline ever since. Using the concepts of trust and friendship, the article suggests that the lack of trust properties such as empathy, bonding, reliability and predictability have contributed to the deterioration of trust at both elite and popular levels.     

Immigrants,welfare reform,and the economy

The welfare reform bill adopted in the United States in 1996 limited the eligibility of immigrants for several government assistance programs, and early projections estimated that nearly half of the savings associated with the reforms would come from these immigrant restrictions. Several studies have found that subsequent program participation declined more for immigrants relative to natives, seemingly verifying the early projections. However, many of these restrictions were either rescinded by the federal government or superceded by state and local policies. In this paper, we first reproduce earlier findings that show the relative declines in program use among immigrants. We then show that much, but not all, of the relative decline in program use among immigrants can be explained by changing macroeconomic conditions. © 2004 by the Association for Public Policy Analysis and Management.
