Investigating Residential History Using Stable Hydrogen and Oxygen Isotopes of Human Hair and Drinking Water

The relationship between isotopic signals in human hair and geographic region has potential forensic applications for identifying unknown individuals' place of recent residence. This study analyzes δ²H and δ¹⁸O isotopes in residential tap water and bulk hair samples from 17 volunteers representing 12 locations in Ontario, Canada. There is a strong correlation (R² = 0.9) between δ²H and δ¹⁸O values of the water samples. In contrast, the δ²H and δ¹⁸O values of the hair samples are weakly correlated (R² = 0.3), and the greater variability in the data is linked to dietary factors. This study demonstrates that the δ²H and δ¹⁸O values of hair and drinking water can be used to help identify potential place of residence in forensic cases, particularly in relation to proximity to large bodies of water such as the Great Lakes, but interpretations are complicated by the contribution of both water and diet to δ²H and δ¹⁸O values in hair.     

Critical Punishment Memorialization in Canada

Recent criminological scholarship on penal history museums has shown how sites of popular culture tend to silence the voices of prisoners and present them in ways that legitimate the deprivation of their liberty. While representations that reinforce the penal status quo are observable at most Canadian penal history sites, there are outliers that situate imprisonment as a form of oppression, and account for prisoners’ struggles and resistance. Drawing on three case studies from a 5-year qualitative research project on Canadian lock-up, jail, prison and penitentiary museums, we discuss what critical punishment memorialization looks like in a context of penal intensification in Canada. We show how such critical representations depend on the historical contextualization of penality as a manifestation of colonialism and/or the incorporation of prisoners’ voices and standpoint. We argue that the critical representations and narratives at these museum sites open up possibilities for the social distance between penal spectators and the incarcerated to be diminished by bringing humanizing prisoner narratives into focus in an otherwise dark tourist space.

A Bayesian Approach to Age‐at‐Death Estimation from Osteoarthritis of the Shoulder in Modern North Americans

Osteoarthritis (OA) is a marker of degeneration within the skeleton, frequently associated with age. This study quantifies the correlation between OA and age‐at‐death and investigates the utility of shoulder OA as a forensic age indicator using a modern North American sample of 206 individuals. Lipping, surface porosity, osteophyte formation, eburnation, and percentage of joint surface affected were recorded on an ordinal scale and summed to create composite scores that were assigned a specific phase. Spearman's correlation indicated a positive relationship between each composite score and age (right shoulder = 0.752; left shoulder = 0.734). Transition analysis revealed a tendency toward earlier degeneration of the right shoulder. Bayesian statistics generated phase‐related age estimates based on highest posterior density regions. Best age estimates were into the seventh decade at the 90th and 50th percentile. The proposed method supplements traditional techniques by providing age estimates beyond a homogenous 50+ age cohort.     

Sugar and spice and everything nice? Exploring institutional misconduct among serious and violent female delinquents

Purpose

Despite an emerging body of research on the institutional behavior and adjustment of delinquent males, there exists little information on the incarceration experiences of female delinquents. The present study explored the incidence, prevalence, and determinants of institutional misconduct among a sample of 139 serious and violent delinquent females sentenced to state juvenile incarceration.

Methods

Secondary data analysis was used for the present study. Data utilized were derived from information originally gathered by correctional staff during intake at a state Youth Correctional System (a pseudonym) and during an offender's entire incarceration through on-site diagnostic processes, staff observations, official records, and offender self-reports.

Results

Members of the study sample engaged in roughly 700 incidents of major misconduct and more than 12,000 instances of minor institutional misconduct during their incarceration. Results from negative binomial regression models examining four different types of institutional misconduct revealed that age at commitment, offense type, mental health status, and gang affiliation were related to the expected rate of misconduct, although this varied by misconduct type.

Conclusions

Institutionalization is not necessarily a period of desistance from offending for all delinquent girls. As institutional misconduct may impact post-release recidivism, it is important to identify and intervene with at-risk juveniles during periods of incarceration.     

An Examination of Authoritarian Personality Traits among Police Officers: The Role of Experience

This study compared authoritarian traits as determined by MMPI-2 scores between inexperienced versus experienced police officers. The purpose of this comparison was to investigate whether experienced police officers possessed higher levels of authoritarian traits which may be related to years on the job. Results found that inexperienced and experienced police officers tend to be psychologically healthy and do not possess high levels of authoritarian traits. Some specific differences emerged with inexperienced police officers demonstrating higher scores on ASP (antisocial practices) but lower scores on HY (emotional reactions to stress). Possible reasons for these results are discussed.     

Early Childhood Trauma Impact on Adolescent Brain Development,Decision Making Abilities,and Delinquent Behaviors: Policy Implications for Juveniles Tried in Adult Court Systems

By examining previous literature on the brain’s developmental process during adolescence, this paper aims to determine how early childhood trauma potentially effects decision making in adolescence through exploring self-regulation theory. Through a self-regulation framework, the hope is to determine the connection, if any, between early childhood trauma, delinquent behavior, and involvement in the juvenile justice system. The author insists that not only do adolescents have less culpability due to their brain developmental stage compared to adults, but also early childhood trauma puts adolescents at a greater risk of impaired self-regulation which allows for more probable delinquent behavior. This paper also considers implications for social policy makers and youth advocates concerned with juvenile offenders tried in adult courts and existing racial disparities in the system.     

(Re)Claiming Our Expertise: Parsing Large Text Corpora With Manually Validated and Organic Dictionaries

Content analysis of large-scale textual data sets poses myriad problems, particularly when researchers seek to analyze content that is both theoretically derived and context dependent. In this piece, we detail the approach we developed to tackle the analysis of the context-dependent content of political incivility. After describing our manually validated organic dictionaries approach, we compare the method to others we could have used and then replicate the method in a different—but still context-dependent—project examining political issue content on social media. We conclude by summarizing the strengths and weaknesses of the approach and offering suggestions for future research that can refine and expand the method.
