How “Standardized” is Standardized? A Validation of Postcranial Landmark Locations

Since the mid‐1990s, osteometrics have been a major aspect in forensic anthropology. However, recent evidence has shown that practitioners have been using differing points to establish certain measurements; namely those involving the clavicle, scapula, ulna, femur, and tibia. Engaging 61 practitioners, this study examined and confirmed how extensive this discord is. The highest consistency rate among practitioners was the scapular breadth (62.3%), followed by the femoral anteroposterior subtrochanteric diameter (55%). All other levels fell below these, particularly the physiological length of the ulna which was the most inconsistently measured bone. Furthermore, these low consistency rates yielded percent mean differences between two and 20% of the measurement length, with ranges averaging 14 mm. In light of these results, it is recommended that the field take steps to improve the standardization of such problematic measurements, including reexamining all measurements currently listed in osteometric texts, reassessing the utility of each, and reissuing a comprehensive guide.     

An Examination of Defendant Sex Disparity in Capital Sentencing: A Propensity Score Matching Approach

Although much prior work has examined the influence of extralegal factors on jury capital sentencing decision-making, the influence of defendant sex has been largely omitted from previous investigations. Using propensity score matching methods, the current study analyzes data from the North Carolina Capital Sentencing Project to examine whether “sex matters” in capital sentencing. Findings demonstrated that prior to matching there was a significant difference in the likelihood of receiving the death penalty for female and male defendant cases; however, after matching cases on an array of legal and extralegal case characteristics, these differences were no longer significant. Further results revealed that male defendants’ cases included different aggravating and mitigating factors than female defendants’ cases and that female defendants had limited “paths” to capital trials. Findings suggest that any apparent sex effects that are observed in capital sentencing stem from real differences in the case characteristics found in female and male defendants’ cases rather than any direct effects of defendant sex on jury decision-making. Study limitations and implications for death penalty research are also discussed.     

Injecting Drug Use and the Performance of Rural Femininity: An Ethnographic Study of Female Injecting Drug Users in Rural North Wales

In this article I explore, through the analysis of ethnographic data, the demands of gender and place as they play themselves out in the lives of female injecting drug users (IDUs) in the rural communities of North Wales. The findings point to the array of role-relationships which women (attempt to) manage whilst also pursuing an IDU career and highlight how living in a rural community of place shapes how women attribute meaning to, and experience, injecting drug use. By incorporating theoretical ideas around gender performativity and gender spatiality, the analysis provides some understanding of how female IDUs construct their ‘risk’ behaviour within their own socially embedded and culturally meaningful discourses. The findings suggest the importance of an understanding of gender and place dynamics in the development of effective intervention strategies.     

The relationship between investigative interviewing experience and open-ended question usage

We present three studies examining the role of prior job experience in interviewing and interviewers' ability to learn open-ended questions during a training program. We predicted a negative relationship such that more experienced interviewers would perform worse after training than less experienced interviewers, and that (irrespective of baseline performance) the more experienced interviewers would improve the least during training. These predictions were made for two reasons. First, specific questions are commonly used in the workplace (i.e. open-ended questioning constitutes new learning). Second, experience in the use of specific questions potentially interferes with newly learned open-ended questions. Overall, our predictions were supported across different participant samples (including police officers specialized in child abuse investigation and social workers from the child protection area), time delays, and modes of training. The results highlight the need for investment in ongoing investigative interviewing training commencing early during professionals' careers, prior to the establishment of long-term habits in the use of specific questions.     

Impact of Intimate Partner Violence on Women’s Mental Health

This study aimed to explore the mental health needs of women residing in domestic violence shelters; more specifically, we aimed to identify commonalities and differences among their mental health needs. For this purpose, qualitative and quantitative data was collected from 35 women from a Midwestern domestic violence shelter. Hierarchical clustering was applied to quantitative data, and the analysis indicated a three-cluster solution. Data from the qualitative analysis also supported the differentiation of women into three distinct groups, which were interpreted as: (A) ready to change, (B) focused on negative symptoms, and (C) focused on feelings of guilt and self-blame.     

Emotional Dysregulation and Negative Affect Mediate the Relationship Between Maternal History of Child Maltreatment and Maternal Child Abuse Potential

Risk for committing child abuse is frequently attributed to an intergenerational “cycle of violence” through which abuse as a child increases risk for committing abuse as a parent. While this hypothesis has support, more research is needed to understand the factors that account for this pattern of risk. Given literature suggesting that adults with a history of child maltreatment have increased risk for a wide range of psychopathology, this study examined the role of two behavioral endophenotypes, emotional dysregulation and negative affect, in the association between maternal experiences of childhood maltreatment and maternal child abuse potential among 83 low-income, primarily African-American mothers of elementary school age children. Results indicate that a mother’s experience of abuse as a child predicts later risk for abusive parenting as measured by child abuse potential scores. However, our data also indicate that the relationship between maternal experience of child abuse and later child abuse potential is mediated by maternal emotional dysregulation and negative affect.     

Should algorithms be regulated by government?

There has been, and continues to be, an explosion in the use of algorithms across the economy and society. There are growing concerns about how algorithms are being used and whether they are accountable. This article reviews the literature on the issue of algorithms in several key areas, such as fairness, accountability, and transparency. The article examines arguments on why algorithms should be regulated, and it explores the available literature to identify how a potential Canadian regulatory framework may be developed.     

Use of laser-scanning confocal microscopy in the detection of diagenesis in bone

This research demonstrates the value of laser scanning confocal microscopy (LSCM) as a research tool in osteological studies, and diagenetic studies in particular. LSCM combines properties of light and scanning electron microscopy using laser light to excite fluorophores throughout the z-axis, developing a 3-D image. Using differential staining and selecting for specific wavelengths of light, one can image targeted materials. This research is divided into two parts: visualizing bone structures such as proteins and their decompositional products and visualizing diagenesis. Part one of this study utilized pig bones as a means of testing the overall ability of LSCM to fluoresce bone. Twenty-three samples were imaged, including 13 samples from a decompositional study conducted 5 years previous, and 10 “fresh” samples collected from a commercial butcher. This part of the study determined that protein and organic components of the bone could be fluoresced and diagenetic alteration could be imaged. The second part of the study used human samples as a means of imaging and mapping diagenetic alterations. The second part of the study used 13 samples, including 4 clinical, 7 ancient, and 2 modern controls. The pig study used Basic Fuchsin and SlowFade Gold stains, while the human study used toluidine blue. Images were also taken with unstained elements. The results of the non-human study found that a fresh bone fluoresced differently than that of a 5-year subset, while the results of the human study confirmed these findings and determined that the bone diagenesis can be mapped using LSCM.     

Packing Heat in the Classroom: Public Support for “Armed Teacher” Policy

ABSTRACT

Recently, states have enacted teacher-carry laws. While controversial, little scholarship has tapped public attitudes toward such reforms. Because public opinion shapes policy, the public is an important stakeholder in this debate. Thus, we investigated three questions. First, how supportive is the public of arming teachers? Second, what demographic and social divides exist, if any, for reform approval? Finally, do crime-related perceptions, concerning views about public safety, and criminogenic influences shape policy preferences? We test these questions using a 2018 poll of Virginia residents (N = 521). Overall, approval for teacher-carry is split. Crime-related perceptions mediate some of the initial social and demographic divides in opinion but other correlates, such as parental status, remain salient predictors of views. Implications are discussed.
