Applying Knowledge of Species‐Typical Scavenging Behavior to the Search and Recovery of Mammalian Skeletal Remains

Forensic investigations involving animal scavenging of human remains require a physical search of the scene and surrounding areas. However, there is currently no standard procedure in the U.K. for physical searches of scavenged human remains. The Winthrop and grid search methods used by police specialist searchers for scavenged remains were examined through the use of mock red fox (Vulpes vulpes) scatter scenes. Forty‐two police specialist searchers from two different regions within the U.K. were divided between those briefed and not briefed with fox‐typical scavenging information. Briefing searchers with scavenging information significantly affected the recovery of scattered bones (χ² = 11.45, df = 1, p = 0.001). Searchers briefed with scavenging information were 2.05 times more likely to recover bones. Adaptions to search methods used by searchers were evident on a regional level, such that searchers more accustom to a peri‐urban to rural region recovered a higher percentage of scattered bones (58.33%, n = 84).     

Sources of injustice among individuals with persistent pain following musculoskeletal injury

Evidence supports the negative impact of perceived injustice on recovery following injury. However, little is known about sources that contribute to injustice perceptions in this context. Therefore, this study systematically investigated sources of injustice following painful musculoskeletal injury. Following completion of the Injustice Experiences Questionnaire (IEQ) and measures of pain, depression, and disability, participants completed a semi-structured interview to discuss reasons underlying their IEQ responses. On average, the sample was experiencing moderate levels of pain, depression, and disability, and clinically meaningful levels of perceived injustice. Participants frequently identified employers/colleagues, other drivers, insurers, healthcare providers, family, significant others, friends, and society as sources of injustice. Common reasons for identifying these sources included their contribution to the injury, inadequate assessment or treatment of pain, and punitive responses toward participants’ pain expression. Sex- and injury-related differences emerged in the identification of injustice sources. Potential strategies for preventing perceived injustice following painful injury are discussed.     

Evaluation of Internal Standards for the Analysis of Ignitable Liquids in Fire Debris

Abstract:  An evaluation of eight compounds for use as an internal standard in fire debris analysis was conducted. Tests were conducted on tetrachloroethylene, chlorobenzene, n-octylbenzene, 3-phenyltolune, and deuterated compounds toluene-d8, styrene-d8, naphthalene-d8, and diphenyl-d10 to measure the extraction efficiency of each compound in the presence of an interfering volatile compound (carbon disulfide). Other tests were conducted to evaluate whether or not the presence of an ignitable liquid or pyrolysis/combustion products from fire debris would interfere with the identification of these compounds when used as an internal standard. The results showed that while any of the eight compounds could be used as an internal standard in fire debris analysis, the more volatile compounds (toluene-d8, tetrachloroethylene, chlorobenzene, and styrene-d8) showed better extraction efficiencies at room temperature than when heated to 60°C. Each of the less volatile compounds (naphthalene-d8, diphenyl-d10, n-octylbenzene, and 3-phenyltolune) performed well during extraction at 60°C, while naphthalene-d8 showed better extraction efficiency in the presence of competing volatiles when extracted at room temperature.     

The PCL: YV and recidivism in male and female juveniles: a follow-up into young adulthood

Adolescents, and most recently, adolescent females, have emerged as an important population in violence risk assessment and have sparked a debate regarding the downward and gendered extension of the Psychopathy Checklist: Youth Version (PCL:YV). This article evaluates the differential prediction of the three and four-factor models of the PCL:YV for male (n=201) and female (n=55) juvenile offenders using a prospective four and one-half year follow-up (M=3 years) study. Both models of the PCL:YV were significant predictors for boys; however, contrary to findings from studies using shorter follow-up periods, the predictive power was due primarily to the behavioral features of psychopathy. The PCL:YV was not a significant predictor of non-violent or violent recidivism for girls. This study does not lend support for the use of the PCL:YV as a risk factor for girl offenders. More research is needed to understand the application of the psychopathy construct in youth, particularly in girls.     

Psychopathy among prisoners in England and Wales

Most research into psychopathy among prisoners is based on selected samples. It remains unclear whether prevalences are lower among European populations. This study aimed to measure the prevalence of psychopathy, and the distribution and correlates of psychopathic traits in a representative national sample of prisoners. Psychopathy was measured using the revised Psychopathy Checklist (PCL-R) in a second stage, cross-sectional survey of prisoners in England and Wales in 1997 (n = 496). Poisson regression analysis was carried out to examine independent associations between correlates and PCL-R total and factor scores. The prevalence of categorically diagnosed psychopathy at a cut off of 30 was 7.7% (95%CI 5.2–10.9) in men and 1.9% (95%CI 0.2–6.9) in women. Psychopathic traits were less prevalent among women. They were correlated with younger age, repeated imprisonment, detention in higher security, disciplinary infractions, antisocial, narcissistic, histrionic, and schizoid personality disorders, and substance misuse, but not neurotic disorders or schizophrenia. The study concluded that psychopathy and psychopathic traits are prevalent among male prisoners in England and Wales but lower than in most previous studies using selected samples. However, most correlates with psychopathic traits were similar to other studies. Psychopathy identifies the extreme of a spectrum of social and behavioral problems among prisoners.     

Who’s Afraid of the Big Bad Methods? Methodological Games and Role Play

In terms of gamification within political science, some fields—particularly international relations and American politics—have received more attention than others. One of the most underserved parts of the discipline is research methods; a course that, coincidentally, is frequently cited as one that instructors hate to teach and students hate to take. Given the well-documented merits of games in promoting student engagement and the key role of methods as a building block to student understanding of political science, this article attempts to rectify this oversight by introducing three games—Zendo, Murder Mystery, and the Archeologist’s Quandary— geared at teaching key concepts and approaches in research methods.     

Foreign aid,democracy, and gender quota laws

Why do so many developing countries have gender quota policies? This article argues that foreign aid programmes influence developing countries to adopt policies aimed at fulfilling international norms regarding gender equality. This relationship is driven by two causal mechanisms. On the one hand, countries may use gender quotas as a signal to improve their standing in the international hierarchy, possibly as an end unto itself, but more likely as a means towards ensuring future aid flows. On the other, countries may adopt gender quotas as a result of successful foreign aid interventions specifically designed to promote women’s empowerment. I test these two causal mechanisms using data on foreign aid commitments to 173 non-OECD countries from 1974 to 2012. The results suggest that while programmes targeting women’s empowerment may have some influence on quota adoption, developing countries dependent on United States foreign aid are also likely to use gender quotas as signalling devices rather than as a result of ongoing liberalization efforts.     

Risk and Outcomes: Are Adolescents Charged with Sex Offenses Different from Other Adolescent Offenders?

Juveniles who have committed sexual offenses are subject to specialized treatment and policies based on their assumed unique dangerousness, despite contradictory evidence. Limited information is available regarding risk factors and their relationships to outcomes in this population. The comparative frequency and predictive utility of empirically supported risk factors for general delinquency were examined using data from the Pathways to Desistance study. Adolescent males who committed sexual offenses (n = 127) were compared to adolescent males who committed non-sexual offenses (n = 1021). At the start of the study, the sample ranged in age from 14 to 18 (M = 16.00, SD = 1.12) and self-identified as primarily African American (44 %), Latino (29 %), or White (25 %). Outcomes were measured over 7 years and included general and sexual recidivism, involvement in school and work, and positive relationships with peers and adults. The results indicated a few small differences in the presence of risk factors and their relationship to outcomes, with many similarities. Juveniles who have committed sexual offenses had equivalent general recidivism but higher sexual recidivism, though this rate was low (7.87 %, or 10 of the 127 adolescents who had committed sexual offenses). New clinical and policy approaches may be needed given the similarities between groups.     

Disrupting (gendered) Islamophobia: the practice of feminist ijtihad to support the agency of young Muslim women

Muslim feminist scholars highlight, and seek to transform, racist, sexist and Islamophobic discourses through feminist interpretations of their religion. This paper reports on data gathered from an interview-based study involving four young Muslim women from the same Brisbane (Queensland) community. The focus is on how these young women are understanding, and finding spaces of agency, within these discourses with reference to their faith. The Islamic principle of ijtihad (jurisprudential interpretation of religious text) and the practice of feminist ijtihad are theorized as powerful tools in supporting the young women to counter the Islamophobia and gendered Islamophobia in their lives. Using these tools, however, as this paper argues, is not unproblematic and can reinscribe disempowering gender and ethno-cultural relations. Amid unprecedented gendered Islamophobia and the clear imperative of supporting Muslim women to access the tools of feminist ijtihad, the paper provides important insight into the possibilities and problematics of these tools.
