Influence of confidence inflation and explanations for changes in confidence on evaluations of eyewitness identification accuracy

Guidelines for conducting police line‐ups typically recommend immediate assessment of eyewitness confidence following identification. This confidence level can presumably be used to estimate accuracy even in the presence of subsequently inflated confidence. In this experiment, we examined students' perceptions of immediate and inflated confidence and whether their reliance on confidence varies as a function of the explanations given by the eyewitness for her inflated confidence. Each of 126 university students viewed one of five versions of a videotaped officer–eyewitness interaction depicting an eyewitness identification and follow‐up interview in which the eyewitness gave a (1) high or (2) moderate level of confidence or inflated her confidence and gave a (3) confidence epiphany, (4) memory contamination, or (5) no explanation for the inflation. The memory contamination and confidence epiphany explanations led to lower ratings of identification accuracy as compared to the high‐confidence control condition, supporting the immediate confidence recommendation but in some ways contradicting previous research on this issue. The results suggest the need for further research to understand the conditions under which confidence inflation influences juror evaluations of eyewitness identification.     

Associations Between Caregiver Support, Bullying, and Depressive Symptomatology Among Sexual Minority and Heterosexual Girls: Results from the 2008 Boston Youth Survey

Although sexual minority (SM) youth are at an increased risk for being bullied and experiencing depression, it is unclear how caregiver support is interrelated with those variables. Therefore, we sought to assess: (a) the prevalence of nonphysical bullying, depressive symptomatology, and caregiver support among heterosexual and SM girls, (b) the association between caregiver support and bullying in both groups, and (c) whether sexual orientation moderates the interactive effect of caregiver support and bullying on depressive symptoms. Data come from a survey of students in 22 Boston public high schools; 99 of the 832 girls in the analytic sample were SM. We used chi-square statistics to examine group differences, and multiple regression to estimate the association between the caregiver support, sexual orientation, being bullied, and depressive symptomatology. SM girls reported similar levels of caregiver support as heterosexual girls, but reported higher levels of depressive symptomatology. They were also more likely to report nonphysical bullying. Tests for interactions were not statistically significant, suggesting that bullying, caregiver support, and sexual orientation are independently associated with depressive symptomatology.     

Accounting for Future Generations: Intergenerational Equity in Australia1

Australian governments have published three intergenerational reports since 2002. In line with a general international trend these reports pointed to a problem said to arise from an ageing population which exposes Australia to the risk of a future major fiscal crisis. In this article we argue that by failing to use a generational accounting framework, the reports privilege the elderly at the expense of young people. Added to this, they fail to engage any discussion of intergenerational equity defined as distributive fairness and justice. In this article we explore the value of various approaches to intergenerational justice, focusing on the Principle of Intergenerational Neutrality derived from Rawls' theory of justice. We argue that this does not work as well from a policy point of view as Sen's freedom‐as‐capabilities approach. We conclude that linking Sen's approach to justice to a generational accounting will enable governments to address future issues of equity.     

Mandated Community Service in High School and Subsequent Civic Engagement: The Case of the “Double Cohort” in Ontario,Canada

In 1999, the Ontario provincial government introduced into its high school curriculum a requirement that students complete 40 h of volunteer community service before graduation. At the same time, the high school curriculum was shortened from five years to four. Consequently, the 2003 graduating class of Ontario high school students contained two cohorts, the first of the 4-year cohorts that was compelled to complete a mandated community service requirement, and the last of the 5-year cohorts that was not. Using a quasi-experimental design, we surveyed 1768 first-year university students in terms of their perceptions and attitudes about the nature and amount of previous volunteering, attitudes towards community service, current service involvement and other measures of civic and political engagement. Comparisons of the two cohorts indicate that, while there were discernible differences between the two cohorts in terms of their past record of community service, there were no differences in current attitudes and civic engagement that might plausibly be attributed to participation in the mandatory service program. Results are discussed with relation to the current debate concerning the impact of mandatory volunteering policies on intrinsic motivation to volunteer.

Recovery of Environmental Human DNA by Insects*,†

Abstract: We tested the hypotheses that foraging insects can acquire human DNA from the environment and that insect‐delivered human DNA is of sufficient quantity and quality to permit standard forensic analyses. Houseflies, German cockroaches, and camel crickets were exposed to dusty surfaces and then assayed for human mitochondrial and nuclear loci by conventional and qPCR, and multiplex STR amplification. Over two experiments, 100% of insect groups and 94% of dust controls tested positive for human DNA. Of 177 individuals, 33–67% tested positive and 13 yielded quantifiable human DNA (mean = 0.022 ± 0.006 ng; mean dust control = 2.448 ± 0.960 ng); four had at least one positive allele call for one or more locus; eight others showed multiple peaks at some loci. Results imply that application to routine forensic casework is limited given current detection methodology yet demonstrate the potential use of insects as environmental samplers for human DNA.     

Effects of Hurricane Katrina and Other Adverse Life Events on Adolescent Female Offenders: A Test of General Strain Theory

This study tested Agnew's General Strain Theory (GST) by examining the roles of anger, anxiety, and maladaptive coping in mediating the relationship between strain and three outcomes (serious delinquency, minor delinquency, and continued involvement in the juvenile justice system) among adolescent female offenders (N = 261). Strains consisted of adverse life events and exposure to Hurricane Katrina. Greater exposure to Hurricane Katrina was directly related to serious delinquency and maladaptive coping. Hurricane Katrina also had an indirect effect on minor delinquency and Post-Katrina juvenile justice involvement mediated through maladaptive coping. Adverse life events were associated with increased anger, anxiety, and maladaptive coping. Anger mediated the relationship between adverse life events and serious delinquency. Anxiety mediated the relationship between adverse life events and minor delinquency. Maladaptive coping strategies were associated with minor delinquency and juvenile justice involvement. Findings lend support to GST.
