An Investigation into the Relationship between Human Cranial and Pelvic Sexual Dimorphism

When faced with commingled remains, it might be assumed that a more “masculine” pelvis is associated with a more “masculine” cranium, but this relationship has not been specifically tested. This study uses geometric morphometric analyses of pelvic and cranial landmarks to assess whether there is an intra‐individual relationship between the degrees of sexual expression in these two skeletal regions. Principal component and discriminant function scores were used to assess sexual dimorphism in 113 U.S. Black individuals. Correlation values and partial least squares regression (PLS) were used to evaluate intra‐individual relationships. Results indicate that the os coxae is more sexually dimorphic than the cranium, with element shape being more sexually dimorphic than size. PLS and correlation results suggest no significant intra‐individual relationship between pelvic and cranial sexual size or shape expression. Thus, in commingled situations, associations between these skeletal elements cannot be inferred based on degree of “masculinity.”     

A Validation Study of the Langley et al. (2017) Decision Tree Model for Sex Estimation

Langley et al. (2017) developed a sex estimation decision tree utilizing two traditional cranial traits (glabella and mastoid) and a new trait: zygomatic extension. This study aimed to test the reliability of their zygomatic extension scoring method and validate their sex estimation method. Ordinal score data were collected from 281 male and female U.S. White and Black individuals. The five traditional cranial traits were collected from physical specimens, while zygomatic extension was scored from 3D cranial models. Intra‐ and interobserver analyses carried out on a subsample of 30 individuals indicate good agreement between zygomatic scores. The decision tree correctly sexed 71.5% of the sample, but a strong sex bias (94.2% correct for females, 49.3% correct for males) severely limits the utility of this method. The Walker (2008) and Stevenson et al. (2009) methods produced higher accuracy rates (80.8% and 82.6%, respectively), although these methods also produced sex and ancestry biases.

Female sex offenders who abuse children whilst working in organisational contexts: offending,conviction and sentencing

To date, there has been very little research into the phenomenon of female-perpetrated institutional child sexual abuse (CSA). This study explored 71 cases of CSA perpetrated by women working with children, considered by UK police and courts between 2000 and 2016. Qualitative and quantitative content analysis was employed to examine court reports, professional regulatory body decisions, media reports and an online sentencing database in order to identify perpetrator and victim characteristics, the nature of the offending behaviour, modus operandi and criminal justice system responses. Findings indicate most women offended alone and had no previous criminal or employment records of concern. Victims were typically male and 15–16 years old. Most women received custodial sentences, typically of 2–3 years in length. Implications for policy and practice are also discussed.     

The Static-99R predicts sexual and violent recidivism for individuals with low intellectual functioning*

A current debate is whether actuarial risk assessment tools predict sexual recidivism in sexual offenders with intellectual disabilities (SOIDs). Since intellectual functioning exists on a spectrum, the present study examined the predictive validity of the Static-99R across the range of intellectual functioning. The sample was comprised of 454 adult sexual offenders assessed at an outpatient clinic and followed for an average of 10 years. Offenders in the extremely low/borderline group had higher scores on the Static-99R than other offenders, largely due to their score on the detachment subscale of the Static-99R, but did not have significantly higher recidivism rates. Calibration analyses suggested that the expected and observed recidivism rates did not differ significantly. Intellectual functioning did not add incremental validity to the Static-99R. Further, there was no interaction between intellectual functioning and actuarial risk score. The results suggested that the Static-99R can be used across the range of intellectual functioning, albeit somewhat more cautiously for those at the lowest and highest end of the intellectual functioning distribution.     

Risk-Need-Responsivity applications of the MMPI-2 in sexual offender assessment

The present investigation examined the risk, need, and responsivity (RNR) correlates of MMPI-2 scores in a Canadian sample of 349 federally incarcerated sex offenders, followed up prospectively 19 years post-release. In terms of responsivity indicators, more serious profile patterns were associated with younger age, single marital status, lower education, and lower cognitive ability; the scales generally had weak associations with sex offender treatment completion or change. With respect to criminogenic risk and need, Scales F, 4, 6, 8, and 9 and combinations therein had significant associations with structured measures of sex offender risk, and in turn, consistently predicted sexual or violent recidivism over 5 and 10-year follow-ups. Several of these predictive associations were maintained even after controlling for static and dynamic risk factors. Finally, model based clustering of the MMPI-2 scales generated three clusters termed disordered, emotionally distressed, and predominantly antisocial (non-disordered) subtypes. Although comparatively higher rates of violent recidivism were found with the disordered subtype, this group did not have higher levels of risk and need, broadly speaking, than the other subtypes. The RNR implications of the results are discussed in terms of forensic applications of MMPI-2 with sex offender populations.     

Trials of Women for Homicide in Nineteenth-Century England

This study examines the rates of trial of women on charges of murder at five yearly intervals from 1845 to 1900. Most women in the nineteenth century were charged with murdering their new-born infants or older children, though few were convicted. Also discussed are the rates of trial for charges of "concealment of birth," a charge frequently used when a jury was reluctant to convict an accused woman of the more serious charge of murder.     

Hot spot trafficking: a theoretical discussion of the potential problems associated with targeted policing and the eradication of sex trafficking in the United States

Throughout the United States, legal professionals and advocates have taken measures to address the access to victims of sex trafficking. A commonly accepted practice has been to advocate for the removal of ‘sex for sale’ advertising in free media such as Craigslist and Backpage. Although this action against the solicitation of prostitution has been celebrated by many advocates and legal professionals, the removal of such advertisements does not directly affect the prevalence of sex trafficking. In fact, displacement theory suggests that the removal of solicitation advertisements and targeted policing forces traffickers to simply advertise elsewhere or become more creative in selling the victims, thereby concealing the act of sex trafficking and making it less identifiable. Although we do not advocate for the maintenance of ‘sex for sale’ advertisements, the process of removing these ads is counterproductive, having little positive impact on the incidence of sex trafficking in the United States. Rather, it forces both traffickers and victims to bury deeper in the already hidden world of sex trafficking. Policy implications derived from criminal displacement theory and research are provided.     

Review of “Creative Subversions: Whiteness,Indigeneity, and the National Imaginary,” by Margot Francis

Narrative is not only entertainment but also a mode of engaging in negotiation with others, and culture is one of the things negotiated thereby. Stories are structured by an internal and external authority in terms of origin, coherence, and effectiveness in the world. Cultural managers will inevitably be involved in situations where narratives diverge, and they will discover that dealing with competing narratives involves a type of diplomatic communication with a range of participants in the arena of culture, from artists to civic authorities to audiences. Historical anecdotes from both classical and modern eras suggest how powerful cultural credit and cultural production can be and how ideas of culture can be deployed in politics. The slow and careful procedures of diplomacy—taken analogously as communication, protection, negotiation, and sovereignty—can prevent even domestic cultural management from provoking hostility or resistance to a perceived attempt to exert control. Ultimately, we are mostly living in a fluid rather than a precisely calibrated world, and cultural managers know that absolute justifications for cultural work are impossible to find.     

Offending histories and offending behaviour: A Ten year follow-up of sex offenders tried by Sheriff and District Courts in Grampian,Scotland

From criminal complaint records all incidents of sexual misbehaviour resulting in charges in three North East Scotland courts during 1981 and 1982 were traced. Of the 80 alleged offenders, 75 were followed up for 10 years using current criminal records.

Offending behaviour ranged from obscene telephone calls to rape. Half the offenders made no physical contact with their victims. These “hands-off” offenders were compared with “hands-on” offenders and were found to show a higher prevalence of sexual convictions both before the index offence and in the follow-up period. Those offenders who removed their victims clothes or had sexual intercourse with their victims were found to have the lowest prevalence of sexual reoffending. Degree of intrusiveness was inversely related to sexual recidivism in this sample and there was no evidence of progression over time to more intrusive offending.
