An assessment of the accuracy of discriminant function equations for sex determination of the femur and tibia from a South African population

The purpose of this study is to test the accuracy of seven discriminant function equations that have been derived by Steyn and Is?an for sex determination using measurements of the femur and tibia of South Africans of European descent (SAED). While the validity of some of the discriminant functions has been assessed by the authors who derived them, no previous independent study has been carried out to assess the accuracy of these equations. These equations have not been tested on skeletons located outside of the Gauteng province. A suite of measurements were taken on 272 femora and 256 tibiae obtained from four South African skeletal collections. The validity of each of the previously published equations for the femur was confirmed. However, two functions of the tibia showed low accuracy rates, most likely due to difficulties in recording the distal epiphyseal breadth measurement, and thus were found to be poor assessors of sex.     

The Effect of Post-ID Feedback on Retrospective Self-Reports in Showups

This study examined the effects of post-identification feedback on witness retrospective self-reports in showups and lineups, and importantly, focused on guilty and innocent suspect identifications. After viewing a mock crime video, participants were asked to identify the suspect from either a target-present or target-absent photo lineup or showup. Participants were randomly assigned to receive confirming feedback (“Great job, you made the correct decision”) or no feedback about their identification, before self-reporting confidence, view, attention, willingness to testify, and trust of a witness with a similar view. We replicated the typical finding that confirming feedback inflated witness self-reports and resulted in a larger proportion of witnesses meeting the credibility threshold necessary to testify. Importantly, we also found that showups had significantly higher self-reports than lineups, despite the equal discriminability achieved in this study between these two procedures. These data provide yet another reason for the police to restrict use of showups.     

Beliefs about secondary confession evidence: a survey of laypeople and defense attorneys

We surveyed students, community members, and defense attorneys regarding beliefs about secondary confession evidence (i.e. when a third party tells authorities that a person has confessed to him or her) from jailhouse informants and other sources. Results indicated that laypeople perceive secondary confessions as less credible than other types of evidence (e.g. forensics, DNA, eyewitness testimony), and they are knowledgeable about factors that may influence the veracity of secondary confessions, such as incentives or previous testimony. However, they underestimated or were uncertain about how persuasive secondary confessions would be to themselves or other jurors. Compared to laypeople, defense attorneys were more sensitive about issues affecting the reliability of secondary confessions.     

Developmental Markers in Adolescence: Implications for Studies of Pubertal Processes

There is inconsistency in the outcome measures of biological and psychosocial studies using measures of puberty as a predictor. For example, some studies show that maturational timing may have differential influences (positive, negative, or no effect) depending on the specific disorder, dimension of measure, and gender. Other studies have suggested that some effects may be more directly linked to pubertal stage or hormone concentrations rather than timing per se. This study outlines several conceptual and methodological issues that may be relevant to addressing these inconsistencies, in the context of examining data from a study of maturational hormones obtained from a unique longitudinal cohort of 24 girls (age 10.0 ± 1.6 years) and 36 boys (age 10.4 ± 1.6 years) in the early part of puberty, where the developmental trajectory of these hormones were tracked annually in 65% of the sample. We explored the contributions of measures of pubertal growth and sociodemographic factors on hormone concentrations. In brief, it appears that no single measure best captures the maturational processes during puberty and suggests that multiple processes are occurring in parallel. Several conceptual and methodological implications are discussed that may guide investigators in interpreting existing studies of pubertal timing and behavior as well as in conducting future studies.     

Political Science and Prediction: What's Next for U.S. Climate Change Policy?

This article analyzes how U.S. climate change politics and policy making are changing in the public, private and civil society sectors, and how such changes are likely to influence U.S. federal policies. It outlines the current status of U.S. climate change action and explores four overlapping pathways of policy change: (1) the strategic demonstration of the feasibility of climate change action; (2) the creation and expansion of markets; (3) policy diffusion and learning; and (4) the creation and promulgation of norms about the need for more aggressive climate change action. These four pathways seek to fruitfully draw from rationalist and constructivist approaches to policy analysis, without collapsing or confusing the different logics. Building on this analysis, it predicts that future federal U.S. climate policy will include six major components: (1) A national cap on GHG emissions; (2) A national market based cap‐and‐trade GHG emissions trading scheme; (3) Mandatory renewable energy portfolio standards; (4) Increased national product standards for energy efficiency; (5) Increased vehicle fleet energy efficiency standards; and (6) Increased federal incentives for research and development on energy efficiency issues and renewable energy development. In addition, expanding federal climate policy may bring about significant changes in U.S. foreign policy as U.S. international re‐engagement on climate change is likely to occur only after the development of more significant federal policy.     

Using Reentry Simulations to Promote Changes in Attitude toward Offenders: Experiential Learning to Promote Successful Reentry

This research examines the viability of using reentry simulations as a tool for influencing changes in participants’ perspectives about the realities of coming back in the community after a period of incarceration. Using both quantitative and qualitative methodologies, we investigated changes in attitudes toward offenders after participants completed a reentry simulation designed to replicate the experience of the first four weeks in the life of a person attempting to reenter society after incarceration. Participants were 27 students enrolled in a community corrections course that was cross listed and co-taught between criminal justice and social work. Participants completed a quantitative pre- and post-test that assessed attitudes toward prisoners as well as a reflection assignment about the simulation experience. Wilcoxon Signed Rank Test was used to analyze scores from pre- and post-tests. Qualitative analysis of the reflection papers identified and analyzed themes. Both quantitative and qualitative analysis indicate that simulations humanize perspectives toward former offenders and develop a better understanding of their situation. This understanding creates empathetic feelings that can reduce discrimination and stigma, thereby creating an environment more conducive to successful reintegration. Based on the results of this study, use of simulation-based training is recommended with audiences including criminal justice personnel, service providers, court practitioners, judges, and legislators as a way to more clearly articulate the realities faced by this vulnerable population.

     

The Cross-Dresser,the Thief,His Daughter and Her Lover: Queer Desire and Romance in Georgette Heyer’s These Old Shades

When romance fiction consolidated as a genre in the 1920s and 1930s, a series of generic conventions concerning the heterosexual imperatives came about. This article considers how these heterosexual imperatives function as a mask for queer desire in Georgette Heyer’s These Old Shades (1926). Drawing on the work of Eve Kosofsky Sedgwick, the article identifies in the novel a detailed account of male–male desire through arguing that while the romantic narrative is concerned with the Duc of Avon and Léonie, his former cross-dressing page, the substantial sexual tension in the novel occurs in the meetings and exchanges between Avon and Léonie’s biological father, Henri Saint-Vire. While These Old Shades ends with the presentation of Léonie by Avon as his duchess, it is male–male desire which has (queerly) driven this romance plot to its ‘natural’ conclusion of marriage. The article thinks through what happens when the rivalry, explicitly about desiring a woman, is an implicit homosocial bond and how this functions within the heterosexual imperatives of the romance novel. The article questions how desire functions in the romance novel and, more crucially, how romance fiction can be read as resisting, at least in part, that which has been traditionally understood as their raison d’être—the heterosexual imperative.     

Medicolegal death investigator workplace safety hazards: A scoping review of the literature

In the United States, medicolegal death investigation practices and policies pertaining to sudden unexpected deaths are mandated by state government. Practices vary across states, which contributes to inconsistency in job prerequisites and training. In preparation for a study focused on occupational safety and health of medicolegal death investigators in their on-scene and follow-up activities, a scoping review was conducted to document known occupational safety risks and health-related conditions associated with death investigation. Searches used Boolean and subject heading operators both broad and narrow in scope, and search terms included scene responder, hazard, investigator, forensic pathology, injury, and safety. Twenty-five articles met inclusion criteria, which included seventeen survey-mixed method designs, two systematic reviews, five quasi-experimental designs, and one case study. Twelve articles addressed mental health and eleven focused on risks associated with infectious disease. One article addressed the risk of chemical exposure from cyanide among autopsy personnel (including forensic pathologists) and nine included a wide range of employees within the setting of medical examiner or coroner offices. One article, addressing burnout, included employees in a forensic science laboratory setting as well as medicolegal death investigators and two articles included forensic pathologists and medicolegal death investigators. Only one article addressed medicolegal death investigators specifically. Articles addressing occupational and environmental hazards of medicolegal death investigators associated with musculoskeletal, respiratory, cardiovascular, radiological, nuclear, electrical, or explosive threats were not identified. There is little published about safety risks inherent in conducting death investigations. Research is needed to adequately inform health promotion and injury prevention strategies.
