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.     

Continuity in Primary School Children’s Eating Problems and the Influence of Parental Feeding Strategies

Eating problems are highly prevalent and seem to show continuity in children. Nevertheless, the effect of different maternal and paternal feeding practices on changes in these problems is not fully understood yet. This study examines short-term continuity in primary school children’s overeating, loss of control (over eating), restraint and concerns (about eating, body shape and weight) and the predictive value of parental feeding strategies on change in these eating problems. Children (8–12 years, n = 613, 46.5 % girls) completed the Child Eating Disorder Examination Questionnaire (ChEDE-Q) twice with the second measurement (T2) taking place 6 months after the first (T1). Parents (n = 714, 57.7 % mothers) completed the Child Feeding Questionnaire (CFQ) at T1 to assess the level of controlling feeding strategies. More overeating, restraint and concerns at T1 predicted higher levels of the same eating problems 6 months later, whereas more of loss of control at T1 predicted lower levels of loss of control 6 months later. Additionally, the interaction between maternal pressure and the gender of the child was predictive for increases in overeating, whereas the interaction between paternal monitoring and gender of the child was a marginally significant predictor for decreases in overeating. These findings point to the possible negative and positive effects of parental feeding practices as well as to the possible larger influence of mothers on their daughters’ and of fathers on their sons’ eating behaviors. The importance of studying mothers and fathers, as well as daughters and sons, and of including different feeding strategies and eating problems is discussed.     

Longitudinal Dynamics of Depressogenic Personality and Attachment Dimensions in Adolescence: An Examination of Associations with Changes in Depressive Symptoms

Depressogenic personality and attachment are two major factors related to the development of adolescents’ depressive symptoms. However, no previous longitudinal studies have examined simultaneously both vulnerability factors in relationship to depressive symptoms. The present study examined associations between intra-individual change in adolescents’ depressogenic personality orientations (i.e., sociotropy and autonomy), dimensions of mother–adolescent attachment (i.e., anxiety and avoidance), and depressive symptoms. The sample of the present research consisted of 289 high school students (mean age = 12.51 years at Time 1, 66 % female) participating in a 3-wave cohort-sequential design. Latent growth curve modeling revealed no significant intra-individual change in depressogenic personality orientations but significant changes in dimensions of attachment and symptoms of depression. Initial levels of sociotropy were not related significantly to changes in attachment dimensions and depressive symptoms. High initial levels of autonomy were associated with increases in attachment anxiety, attachment avoidance, and depressive symptoms. In addition, results suggested that the association between initial levels of autonomy and increases in depressive symptoms was mediated by increases in attachment anxiety and avoidance. The discussion focuses on the status of depressogenic personality and attachment as risk factors for depression.     

Electoral and structural losers and support for a national referendum in the U.S.

The U.S. is one of only a few democracies in the world never to hold a national referendum. Recent national surveys reveal that a majority of respondents approve of a national referendum both cross-nationally and in America is relatively stable. Building on previous work (Bowler and Donovan, 2007), we find public opinion on a reform proposal is fluid and responsive to electoral politics, rather than stable as reported in earlier work. In this paper, we argue that contemporary support for a national referendum in the U.S. is contingent on whether a citizen is a short- or long-term “winner” or a “loser” when it comes to electoral politics. We expect that public support for a national referendum in the U.S., where legislation referred by Congress would be subject to a popular vote, may vary at the individual level because of short-term electoral fortunes as well as long-term structural conditions. Strategic voting as well as losing in candidate races and policy issues may be important, but so might be partisanship, with non-partisans the most likely to benefit from citizen law-making at the national level. Support for a national referendum might also be contingent upon state context, that is, upon use of direct democracy in the state where a person lives, as well as the population of a state. The results based on a natural experiment and 2008 panel survey data provide an important window into understanding public opinion on institutional change more broadly.     

Bringing Home the Bacon or Not? Globalization and Government Respect for Economic and Social Rights

The impact of globalization on human rights has generated substantial debate. On the one hand, those making liberal, free-market arguments assert that globalization has a positive impact on developing countries through the increased generation of wealth (e.g., Garrett 1998; Richards et al. in International Studies Quarterly 45:219–239, 2001; Rodrik in Challenge 41:81–94, 1997). On the other hand, the critical perspective claims that globalization negatively impacts respect for human rights because trading arrangements, while open, are detrimentally uneven (e.g., Carleton 1989; Haggard and Maxfield 1996; Stiglitz and Charlton 2005). However, few have looked at the relationship between globalization and respect for economic and social rights. In order to test this relationship, I examine non-OECD countries utilizing two-stage regression analysis to control for investment-selection factors. I find mixed results for the hypothesis that globalization negatively affects respect for economic and social rights. Consistent with Richards et al. (International Studies Quarterly 45:219–239, 2001), I conclude by arguing for the need to disaggregate globalization in order to determine its true effects.
